Description

The invention relates to a storage device for motor vehicles, goods or the like. It has several parking spaces, with at least one parking space is on a liftable or lowerable platform, wherein the platform at least a pedestal is guided and a movement drive for the platform is provided, wherein the movement drive on a movable rod has a Zugumlenkung for a traction means, wherein one end of the traction means engages the platform and wherein the traction means comprises a length compensating piece.

The aforementioned parking facilities are often used to increase the number of available parking spaces, for example in underground garages, garages, parking garages and so on. The advantage of such generic parking devices is that not only one vehicle but two or more vehicles can be parked on the same base.

There are concepts in which are set from a higher driveway vehicles on a mobile platform and then the platform is lowered all the way down, thus opening up space for another storage option, as well as concepts in which the lowest parking space at ground level with the driveway and above this lowest parking space at least one more movable platform parking facilities provides. The invention basically relates to these different variants. The invention relates predominantly to parking devices for motor vehicles, without wishing to restrict the scope to this particular case. The subject invention is generally suitable to be used as a storage device for other goods, no matter what kind. Thus, when speaking of motor vehicles below, this does not limit the scope of the invention thereto, this is to be understood as an example.

The aforementioned parking devices for motor vehicles are constructed with respect to the respective conditions in the building but also due to different load, different vehicle heights to be set or other dimensions in a large variety of types and built. The individual lot sizes are therefore relatively small, which is why the production is expensive.

The document GB 11 25 083 A shows a lifting device for motor vehicles with the feature combination of the preamble of claim 1, wherein a cable is provided with pulleys to lift a platform.

The invention has therefore taken on the task of further developing the prior art, as described above, and make the shutdown as variable as possible and therefore inexpensive to produce.

To solve this problem, the invention proceeds from a storage device for motor vehicles or goods or the like, as described above, and proposes, as already mentioned, in an embodiment according to the invention, that the movement drive on a movable rod has a tension deflection for a traction means and an end of the traction means engages the platform and the traction means has a length compensating piece.

The concept proposed here according to the invention uses the cable pull principle with the advantage of a "moving roller". The movement path of the movable rod is arbitrarily adjustable, resulting in a high variability in the adjustment of the lifting height of the platform, whereby the lifting height is easily adaptable to the respective conditions. At least it is possible, with an embodiment of the movement drive, as described, to realize a plurality of different lifting heights, whereby the type variety is reduced accordingly and the variability of the storage device is increased accordingly. However, the advantage according to the invention is not limited to this alone. The movement length of the movable rod is not only in the structure of the storage device, ie in their construction or the production or Mounting an advantage, it must also be observed when operating the storage device. The concept according to the invention is suitable in that the movement length of the movable rod is changed accordingly, for example by the user or during maintenance, if, for example, the heights of the vehicles to be parked change accordingly.

Furthermore, by the modified drive concept of the movable roller (in this case, a movable tension diversion), a fast and constant running drive is provided without correspondingly more rapid movement drives, such as with telescopic cylinders and so forth, for a correspondingly fast lowering or lifting movement. to have to make available. The speed of movement of the thus raised platform is twice as high as the speed of movement of the moving train deflection or the moving rod.

Through the use of the length compensation piece, the effective length of the traction means can be varied accordingly. Preferably, the length compensation piece is not designed as a traction device to save costs. As a traction means often finds a joint chain or similar use. However, it has been found that in certain areas of the storage device on the articulation of the traction means is of no value, since this flexibility is not used in certain sections. For this purpose, a length compensation piece is then used in the alternative according to the invention, which is connected to the traction means. If, for example, the setting heights or the end positions of the movable platform change, this results in a correspondingly changed length of the traction means, which is compensated by the corresponding adjustability of the length compensation piece.

According to the invention, it is provided that the adjustment range of the length compensation piece is far more than 10 cm. This allows easy adaptation to different vehicle heights. Cleverly doing this is the length compensation piece at the end of the traction means and connects the traction means, for example, with a corresponding storage of traction means on the storage device or the foundation or the wall or the column base of the building surrounding the storage device.

In addition to the use of a link chain as traction means is of course to be noted that any other traction means can be used here. Since the traction means is often to lead over a tension deflection, a corresponding flexibility or flexibility of advantage, which is why suitable as traction means in addition to joint chains or other chains and wire ropes, ropes and the like.

Furthermore, it can be provided that, in particular below the platform between the two pillars, a Ausgleichszugelement is arranged, wherein the first end of Ausgleichszugelementes on the first pillar and the second end of Ausgleichszugelementes is arranged on the second pedestal and the Ausgleichszugelement by at the Platform arranged deflections is deflected, wherein a pedestal has a plurality of connection points for the Ausgleichszugelement and the platform width is adjustable by the choice of the connection point with the same overall length of the Ausgleichszugelementes.

This approach opens up a high variability in the realization of platforms of different widths with the storage device according to the invention. The compensating tension elements can be prepared in large batches of constant length and then, according to the platform width actually realized at different connection points on the pedestal used become. Since the Ausgleichszugelement runs transversely below the platform, the width of the platform directly affects the length of the Ausgleichszugelementes, which is always adapt according to the prior art.

The proposal that a plurality of connection points is provided on the pillar for the Ausgleichszugelement, it is achieved that it does not arrive in the production of Ausgleichszugelementes or the pillar on the actual platform width, this is, depending on the actual platform width, through considers the selection of the appropriate connection point.

In addition, it can also be provided that on the pedestal a trained as an independent pillar component, optionally interchangeable Ständeräulenfuß is provided.

In the solution according to the prior art, the Standsäulenfuß is always formed integrally fixed to the pedestal. Often, however, the choice of Standsäulenfußes depends on the actual on the construction site soil properties. The variability of the storage device according to the invention is therefore considerably increased when the pedestal is formed as a separate component of the Standsäulenfuß and several Standsäulenfüße, similar to a modular principle, with the then in larger lots pre-producible uprights are connectable.

The solutions according to the prior art know a one-piece connection of pedestal column with Standsäulenfuß (for example, welded), which is very cumbersome to transport, since these variants require a large storage space or a large transport volume. By the solution described herein, however, not only a modular system for the pillar is realized, which adapted to the particular circumstances in the short term can be, there are also significantly lower transport costs generated because the expansive design of Standsäulenfuß stand column combination only really when setting up the storage is necessary, but they can be transported very compactly.

The individual aforementioned measures solve the task initially posed in a convincing manner. The use of the length compensation piece makes it possible to realize a variety of different platform distances with a storage device according to the invention, this advantage has a double effect, namely firstly when setting up the storage device according to the invention, in which only shortly before the actual assembly must be determined, which height or which Type is needed. But even in the operation of the storage device according to the invention then the distance of the individual platforms is easily adaptable to the different vehicle heights, without requiring a completely new storage device. The increase in flexibility and ease of use is surprisingly accompanied by a reduction of storage costs, since a larger lot size of the individual elements can be manufactured and thus the cost price, but also the stockkeeping costs for this are then lower. Since a variety of different types of the prior art are ultimately covered with a type of storage device according to the invention, rarely used, but then available at short notice to be provided components no longer be kept. It should be noted that the increase in comfort both when setting up the storage device according to the invention as well as during their use, ie in use, usually not accompanied by a reduction in the type variety, but usually increases the cost price. However, this is just avoided by the invention.

In addition, it can be provided that in a parking device for motor vehicles, goods or the like as cooperating with the movement drive traction means and /, as running on, in particular under the platform, on the pedestal end Ausgleichszugelement a joint chain is provided, which consists of a plurality of chain links , which are each connected by bolts articulated to each other and each chain link between one and nine tabs, preferably between four and eight tabs.

Cleverly be parked for the various Zugaufgaben in the storage device according to the invention also on a uniformly designed tension member as traction means or Aushilfszugelement. It should be noted that the platform has a minimum load capacity of 19 kN (equivalent to approx. 2000 kg). But since the platforms are also intended for vehicles or goods that can be significantly heavier, the traction device is cleverly designed so that it also easily meets these increased requirements and meets them. The tension member therefore certainly has sufficient strength to easily cope with a platform with a traffic load of more than 25 kN and to meet these requirements. The tension member therefore also has sufficient strength to support and hold a platform with a traffic load of more than 25 kN. Accordingly, such a tension member then has a much higher minimum breaking load.

It has been found that a joint chain, which has each other by bolts hingedly connected chain links and each chain link between one and nine tabs, preferably between four and eight tabs meet these requirements, where it is through the use of a suitably shaped joint chain, as this is also claimed, for example, as Ausgleichszugelement a corresponding manufacturing advantage reach. If, in fact, the storage device is removed and, in particular, the platform's minimum carrying capacity is increased, then the correspondingly designed articulated chain is already aligned therewith and does not need to be additionally replaced.

Cleverly, therefore, not all the traction elements used, ie traction means and Zugausgleichselemente be similar, the effect is already achieved when one of these Zugorgange is designed as described.

By using an identical pulling element as traction means and Ausgleichszugelement, of course, the cost price for this tension member, which is designed as a joint chain as described, lowered accordingly, since then this articulated chain can be prepared in larger lots. Of course, then the storage and spare parts system are simplified accordingly.

It can also be provided a joint chain, in particular for use as traction means and / or as Ausgleichszugelement in a storage device for motor vehicles, goods or the like. The articulated chain consists of a plurality of chain links, which are each connected by bolts articulated to each other, wherein the articulated chain has at least four tabs per chain link and a breaking force of at least 60 kN, preferably at least 100 kN. A so-formed joint chain is characterized in particular by the fact that it can be used variably in aforementioned parking devices and due to the high breaking force, the joint chain can be used either as Ausgleichszugelement and / or as a traction device. The breaking force is of course in a certain safety ratio to the load capacity of the platform and its own weight.

Often, a minimum breaking load of 100 kN for platform load capacities of up to 2 t (equivalent to idealized 20 kN) is considered sufficient for parking devices for motor vehicles. But it is also possible to achieve, for example, by a lighter construction of the platform to a lower minimum breaking load.

The aforementioned objects are described in the description as each independent embodiments. But this does not exclude their common application to a storage device according to the invention.

According to the invention, by changing the effective length of the length compensating piece, the end position of the raised platform can be adapted to the height of the material to be parked on the platform, for example the motor vehicle. The adjustment range of the length compensation piece is far more than 10 cm, it comprises a multiple of the height or the thickness of the platform. The length compensating piece is not to be confused with a setting device for a tight fit of the guided over the movable roller chain, in which a correspondingly large adjustability is not possible. With the aid of the length compensation piece proposed according to the invention, it is achieved that the end position of the raised platform can be varied and adjusted by several 10 cm.

An essential advantage of the invention lies in a variant also in that on the pedestal a releasable locking device is provided, which causes the platform remains independent of the movement drive or traction means in a desired locking position on the pedestal. First, the locking device proposed here has a safety task. In the event that the movement drive, so for example a Hydraulic cylinder or its drive fails, or the traction means, for example, a link chain or the like, ruptures, is not to be expected with an uncontrolled crash of parked on the platform vehicle, because then the proposed locking device acts.

In a preferred embodiment of the invention is further proposed that each indicated by the change in the effective length of the length compensation piece end position of the raised platform is also associated with a locking position of the locking device. Since the locking device is arranged anyway for safety purposes over a larger height range on the pedestal, thus, of course, corresponding locking positions are offered in the possible end positions of the platform in a larger interval. The thus already made available anyway locking device, which otherwise only in these situations auxiliary, namely, when a corresponding defect occurs during the movement, must act, is additionally used by the proposal according to the invention without any additional effort.

In a further variant, it is proposed that the storage device, in particular the in-use storage device, the raised platform is in a first end position, can be brought by a change in the effective length of the length compensation piece in a second, new (upper) end position, said Platform can be loaded in both end positions. It is a merit of the invention that the storage device according to the invention also during operation (not only during assembly), ie in use (but unloaded), with respect to the distances of the platforms, so the available platform distances or their end positions, highly variable is. The storage device can be adjusted, for example, by the user to the respective vehicle height to be set. The adjustment process itself preferably takes place in the unloaded state. For example, the two end positions differ by about 10 cm, but this can only be 2 cm. The difference of the end positions is therefore for example between 2 cm and 20 cm, preferably between 5 cm and 15 cm variable, a grid of 10 cm in this area has proved to be beneficial.

In a preferred variant of the invention it is provided that the lowest parking space is located below the lowermost, movable platform. This variant results in a very simple storage device. For the lowest parking space while no separate platform is used, but for example, the bottom plate on which the storage device is set up. Of course, it should be noted that a vehicle that is on the ramped up platform is not available until the vehicle below is removed. Optionally, this can also be monitored with a corresponding monitoring unit.

Alternatively, of course, it should be noted that even on the lowest parking space, a platform may be provided, for example, if the ground is not passable. This platform is then rigid, for example, not liftable.

Of course, it should also be noted that the invention also includes such storage devices in which the lowest parking space is on a movably arranged platform. Such a variant is conceivable, for example, in pits and so forth, in which by the start-up of the lowermost platform a connection possibility to an access road, which serves for several platforms and is located above the lowest parking space, is provided.

Cleverly, it is provided that the parking spaces are arranged one above the other. Cleverly, the platforms are guided one above the other at a common location, which simplifies the statics accordingly. In addition to this basic arrangement of the parking spaces one above the other, it is of course possible to provide two or more parking spaces, for example, on a correspondingly larger platform next to each other. Such an arrangement is part of the solution according to the invention.

Preferably, the platform comprises a sliding piece, wherein the sliding piece is guided on the pedestal and engages the traction means on the sliding piece. The sliding piece has the task of being slidably displaceable on the pedestal serving as a guide. This will guide the platform to the pedestal. The guides used for this purpose are well known. The arrangement of the traction means on the sliding piece, the lifting force is introduced as close to the bearing point of the platform on the pillar in this and the risk of tilting or tilting is greatly reduced. Moreover, the sliding piece adjoins the platform laterally and a connection of the platform via the sliding piece with the traction means in this lateral area in no way hinders the free accessibility or navigability of the platform.

In order to take into account the static requirements, it is provided that the sliding piece is possibly significantly longer than the height of the cheek or the side support in order to achieve the most stable possible leadership of the platform on the pedestal. The sliding piece is therefore sleeve-like or half-sleeve-like side over the platform upwards. This is especially for example off Fig. 1 and will be described again there.

As a very advantageous it has been found that a preferably hydraulically acting working cylinder is provided as a movement drive, the piston rod serves as a movable rod. Hydraulically acting working cylinders are well known as drive means or lifting means. They are available in large numbers and the technique is very well controlled. They serve as an ideal motion propulsion system because they are capable of providing sufficient lift forces for lifting the vehicle-loaded or two-vehicle loaded platform (s).

According to one embodiment, it is provided that the piston rod of the hydraulically acting working cylinder or of the other working cylinder also acts alternatively on another rod.

Furthermore, it is possible that a spindle drive with a motor, in particular an electric motor, is provided as the motion drive. In this case, a spindle is provided longitudinally movable and the motor, which is fixed, drives a nut, due to which the spindle is axially offset. In this case, for example, a region of the spindle or the entire spindle serve as a movable rod or the spindle acts on a movable rod, which is designed as a separate component.

In principle, however, the invention can also be implemented with a pneumatically operated working cylinder, for example, or else with a ball screw or a toothed rack drive or a linear drive. Advantageously, the drives are designed so that a movable rod is provided, via which the lifting force is transmitted to the platform by means of the traction means.

In a preferred embodiment of the invention it is provided that the Zugumlenkung is designed as a rotatable roller. The use of a rotatable roller as Zugumlenkung is as smooth and known inexpensively. The diameter of the role is skillfully chosen just so that a rich concern of the traction means is guaranteed at the Zugumlenkung bestmöglichst. According to one embodiment, it is in particular proposed that a link chain is used as traction means. The diameter of the rotatable roller is determined in this application to the dimensions of the chain, so their pitch and thickness. Cleverly, the diameter is not too small, so that instead of a rolling movement does not result in grinding on the roller, which can lead to increased wear on the roller and possibly also on the chain.

Cleverly, care is taken to ensure that all Zugumlenkungen or elements that is as identical as possible with the traction elements (be it the traction means or Ausgleichszugelement), ie the same diameter and width has the same width to increase the lot sizes accordingly and the spare parts storage accordingly facilitate.

Thus it turns out that in one variant, the deflection is a deflection roller. The deflection is preferably located on both sides of the respective sides of the platform and causes a deflection of the Ausgleichszugelementes of the vertical in the horizontal or from the horizontal to the vertical.

The following variant has proven to be particularly favorable. Thereafter, a diameter of the deflection roller of 50 mm to 75 mm is proposed, preferably from 55 mm to 65 mm. The requirements of the pulley, and in the same way to the rotatable roller as Zugumlenkung, are correspondingly high. It should be noted that a considerable force acts on the respective deflection and loads the roller bearing accordingly. A sufficiently easy rotation of the roll must be ensured, but at the same time the roll or deflection roll must not be too large, so that this is not visible as possible, especially in the edge region of the platform. Of course, the diameter of the deflection roller also depends on the geometric data of the traction mechanism designed as a link chain. In the specified diameter interval of 50 mm to 75 mm for the deflection roller or the roller, but sufficiently satisfactory results have been achieved. In particular, it has also been found that a further restriction to 55 mm to 65 mm for the diameter of the guide roller or roller represents a very good compromise between the Abrolleigenschaften and the space requirement of the entire deflection at the platform.

As far as is spoken in this context of a diameter of the guide roller or the roller, this is understood to mean the outer diameter or the effective diameter, ie the diameter of the deflection roller on its support surface bounding lateral surface.

Since the deflection roller cooperates with the traction means, in particular the articulated chain, it has been found according to the articulated chain, that a division of the members of at least 13 mm, preferably from 14 mm to 17 mm, in particular from 15.6 mm to 16 mm is very has proved favorable. As a division of the distance of the bolt is considered, which connects the individual chain links articulated. In particular, it should be noted that the articulated chain has a high breaking force of at least 60 kN, preferably at least 100 kN or even 150 kN and more, in the specific field of application. Of course, this very high tensile force must be absorbed by appropriate material in the chain and the chain design, on the other hand, the manufacturability of the chain must remain simple, that is, if possible, a mechanical chain production must be possible and of course the use of the joint chain in a specific application remains possible, that is, the deflection radii or deflection diameter sufficient stay small so you do not need to build large bends. In this particular application, joint chains have been distinguished, the division of the limbs is at least 13 mm, with very good results were achieved in particular in the interval of 14 mm to 17 mm for the application mentioned. Especially in the particularly preferred interval of 15.6 mm to 16 mm for the division of the members, in cooperation with the preferred diameter of the guide roller or the roller of 50 mm to 75 mm, in particular from 55 mm to 65 mm, an effectively cooperating system realized.

It follows, for example, further that the ratio of the diameter of the deflection roller to the division of the chain is less than 5, in particular less than 4.7, preferably between 3.5 and 4. In the specified ratio range results in an optimal load capacity of the chain in relation to deflectability over the role, with sufficiently small diameters of the role.

In a further possible embodiment, it is proposed that the articulated chain has a thickness of at least 11 mm, preferably from 12 mm to 18 mm, in particular from 14.8 mm to 15.3 mm. In addition to the size of the individual members, which is defined by the division, the maximum breaking force of the joint chain also determines the width of the individual tabs but also the thickness of the chain or individual tabs. It has been found that for the application, in particular in a storage device according to the invention, the thickness of the chain is at least 11 mm, preferably 12 mm to 18 mm. Surprisingly, however, a constitution has emerged in the particularly preferred interval of 14.8 mm to 15.3 mm, which can still be used for the necessary deflections and otherwise has a sufficiently high breaking load or carrying capacity. It should be noted that even too thick a chain with too narrow radii reliable power transmission no longer guaranteed and possibly a one-sided load on the chain and the tendency to break increases accordingly.

In this context, it has proved to be favorable that the ratio of diameter of the deflection roller to the thickness of the chain is less than 6, in particular less than 5.5, preferably within the interval of 3.7 to 4.3.

In addition to the respective dimensions of the individual tabs of the chain or the chain link, which is defined by the pitch and the thickness of the chain or tabs, of course, the bolt that connects the individual chain links together, important in the question of stability of the link chain. In the application case discussed here, in which a joint chain with at least a breaking force of 60 kN, preferably at least 100 kN is provided and is defined in particular in connection with the other geometric data of the articulated chain or the ratios to the circumference of the roller, results for the thickness the bolt has a value of at least 4.5 mm, preferably from 5 mm to 7 mm. In particular, a variant of the bolt diameter of 5.8 mm to 6.2 mm in conjunction with a thickness of the chain of 14.8 mm to 15.3 mm has proven to be favorable, since here an optimum of flexibility, bendability and load capacity and total thickness the chain is realized and in particular the use of the articulated chain optimally satisfied in the load range of interest here.

This results according to a variant, a ratio of the thickness of the chain to the diameter of the bolt of at least 2.4, in particular from 2.41 to 2.7, preferably 2.47 to 2.60.

An essential advantage of the invention lies in the fact that the storage device according to the invention is designed to be very variable in order to use as few components as possible, However, they are very flexible to provide a large variety of types, at the same time large lot sizes of the individual elements available. In particular, the adjustability of the lifting height of the platform by the movement drive of interest, since the lifting height is not only set during initial installation, but may also be varied later in the operation of users, if, for example, in winter a small building Caprio on the upper platform is parked and below a larger-building van is set and this use is then reversed in the summer. It is therefore not only important to provide the highest possible variability in the installation of the storage device according to the invention in order to keep the cost price low, it is also an essential part of the invention, the storage device as variable as possible during use to adapt them very easily to the different fields of application and purposes.

It has proved to be very favorable that in a variant, a limiting device for the movement length of the movable rod is provided. The lifting height of the movable rod, in particular if this is realized, for example, as a piston rod of a working cylinder, experiences a corresponding adjustability or limitation or limitation with the aid of the proposed limiting device. The design of this limiting device is very variable and varied.

In a first variant, it is provided, for example, that the limiting device determines at least one end point of the movement of the moving rod. Depending on the design of the motion drive, this may be the upper or lower position of the movable rod. Of course it is possible that both end points, ie the upper and the lower one, are used to limit the movement of the moving rod. By an appropriate arrangement Of course, the entire travel length of the movable rod is also lmitiert and set the end point.

A particular advantage lies in the fact that the limiting device is easy to operate even during operation and, if necessary, can also be operated by the users themselves in reliable and secure form without corresponding maintenance or customer service. Again, this is provided within the scope of the large number of variants of the limiting device and therefore allows a very user-friendly implementation and large variability of the resulting storage device according to the invention.

For this reason, an adjustable limiting device can be provided, by means of which the movement length or the position of the end point or of the end points can be set.

In a first variant, it is provided that the limiting device is designed as a stop, which is variable in particular in its position and / or length, for the rod. The movement of the movable rod is monitored by an appropriate control. If the rod moves against a corresponding stop, that is, the movement space of the rod is limited by a stop, this is detected by a corresponding force-displacement monitoring and the movement drive then turned off, as a further movement, although more energy in the movement drive invested, not done. This can be realized for example by appropriate pressure switch in a hydraulic solution or with contact switches on the stop. It is clear that the end position and / or the effective length, ie the movement length, can be adjusted by the position of the stop. The use of a stop is conceivable for both the upper and the lower end point, if appropriate, two separate stops are then provided for this purpose or it is a stop rail used, each of which has a stop for the upper and the lower end point. In addition to a purely manual design, of course, a corresponding automatic realization is possible, in which electric actuators position the stops accordingly and then hold on to the desired positions.

Alternatively, it is provided in a further variant that the limiting device is designed as a pushed onto the rod sleeve. According to one embodiment, at least one sleeve is provided, it can of course also find an entire set of sleeves use to realize different heights or end positions. Such an embodiment of the limiting device is particularly advantageous for the lower end point, ie for the retracted or retracted rod.

Optionally, the length or position is realized by a plurality of sleeves of the same or different height one above the other or with a kit of sleeves of different heights.

As a further possibility to influence the end points or to influence the movement length of the movable rod, it is provided according to an embodiment to adjust the position of the tension deflection on the rod. For example, the movable rod, for example the piston rod, has a threaded rod which is variable in position or effective length and which is guided in a corresponding threaded bore of the rod and the rod carries the tension deflection at its front end. By a corresponding extension or shortening of the effective length of this threaded rod, the relative position of the Zugumlenkung on the rod is variable and thus can be influenced on the position of the end point or the movement length of the moving or movable rod.

Thus, in a variant, it also follows that the limiting device also acts on the position of the tension deflection and thus increases the variability of a correspondingly configured parking device.

Preferably, a manually adjustable or operable limiting device is provided. The realization as a manually adjustable limiting device has the advantage that it is mechanically easy to implement and yet very reliable.

As an alternative to the manually adjustable limiting device, it is further proposed that the limiting device has an actuating drive (for example electrical) which can be positioned at selectable positions. In such, for example, supported by an electric motor configuration, a desired position is selected and then the actuator, which carries the stop, for example, automatically positioned and so reaches a corresponding restriction or change in the movement length of the movable rod.

It has already been stated that it is favorable that the traction means is connected to the length compensation piece. It is favorable that the length compensating piece has no articulation, since this is usually unnecessary in the application provided here. Conveniently, but the traction means is pivotally connected to the length compensating piece to use the entire length of the traction means, which is indeed articulated or movable, for a deflection, for example, a deflection and so on.

In one embodiment, it is provided that the length compensating piece on the pedestal, on the floor or a wall or on the fixed part of the movement drive (for example on the cylinder the working cylinder) is stored. For the highest possible degree of prefabrication, it is advantageous if the length compensating piece is mounted on an element of the storage device itself, so it is advantageous that the length compensating piece on the pedestal or on any other fixed part of the storage device, such as the motion drive stored is. Alternatively, it is of course possible to attach the length compensating piece to the floor on which the storage device is set up, or to a wall adjacent to the storage device. Although such storage is labor-intensive, since a separate anchor for the length compensation is provided, but nevertheless possible. In particular, the accessibility of the length compensating piece can be changed or improved by such an arrangement, which is just of interest for installations in pits and so on.

Furthermore, it is proposed that the length compensating piece is mounted on the pedestal base. Such an embodiment also allows a corresponding prefabrication and makes optimum use of the space in particular.

In a preferred variant is cleverly proposed that the movement drive, in particular the working cylinder is supported on the Standsäulenfuß. Even so, a correspondingly favorable prefabrication is possible, the assembly is facilitated. In a preferred embodiment of the invention, it is proposed that the smallest possible distance between the bearing mounted on Standsäulenfuß length compensation piece and supported on Standsäulenfuß motion drive is provided. Optionally, the Standsäulenfuß in the region of the support of the movement drive or the storage of the length compensation piece on a corresponding gain. Since the forces that occur are of course limited by a corresponding short distance, the bending moments. A corresponding reinforcement can be welded, for example, as iron or steel piece on the consisting of iron or steel Stand column foot.

In a preferred embodiment of the invention it is provided that the length compensating piece is designed as a turnbuckle. The turnbuckle consists, for example, of a threaded sleeve with threaded studs screwed in at the end. Turnbuckles are well known as a component and as a standardized component in a large variety of lengths (20 cm to 80 cm) with sufficient resistance to breakage available. A significant advantage of the use of turnbuckles is in the invention, in particular, that a high adjustment range due to the length or height of the threaded sleeve and due to the screw drive, a relatively precise adjustment is possible. Also, the turnbuckle for the adjustment activities is easy to operate.

It is favorable that the length compensating piece has a length adjusting device, by means of which the essentially actually rigidly formed length compensating piece can be finely adjusted in its effective length.

According to one embodiment, it is provided that the length compensation piece is rigid in itself, in particular rod-like or similar and has been cut to length, for example from a corresponding rod material and so on. Of course, the material has sufficient strength, which is as possible over the strength of the adjoining the length compensation piece traction means to safely avoid the risk of breakage of the length compensation piece. It will therefore find the typical materials used for this, such as iron, steel and so on.

In a variant, it is provided that the length compensating piece is designed as a threaded rod and a variable in their position on the threaded rod nut the Längeneinstellvorrichtung forms. This is a very simple but at the same time efficient way of realizing the proposed length adjustment device. In particular, a high accuracy can be realized, since the rotation of the nut on the threaded rod can be made stepless and so any necessary measure or length of the length compensation piece can be realized.

In a further variant, it is provided that the length compensating piece is designed as a latching rod, wherein the latching rod has a plurality of detents, which is firmly connected to a stationary with respect to the device storage in the desired length.

In contrast to the aforementioned variant, this variant has only one division into a few predetermined detents, this can of course be supported by a correspondingly short trained, special fine adjustment, for example by a correspondingly rotatable element such as a threaded rod or the like. Cleverly while the distances of the detents are chosen so that the desired Hubhöhenveränderungen the platform is taken into account.

Similar to the embodiment of the limiting device, which can be realized both manually and also by motor or automatically assisted, a length adjustment device supported by an actuator is also proposed. Cleverly, then, for example, a coupling of the control of the two actuators (the length adjustment and the limiting device) may be provided with a selection process to change these two parameters accordingly and set.

In a further variant, it has been proposed that the first end of the Ausgleichszugelementes is arranged on the first pedestal, the central part of the Ausgleichszugelementes transverse to the platform runs and the second end of the Ausgleichszugelementes ends at the second pedestal. Cleverly, the first end of the Ausgleichszugelementes is disposed in the upper region of the first pedestal, preferably above the raised position of the platform. The Ausgleichszugelement has the task of ensuring a synchronization of the platform between the two pillars. The length of the Ausgleichszugelementes is not changed, the Ausgleichszugelement but Z-or double-L-like (opposite directions angled) performed under the platform. Due to the use of this Ausgleichszugelementes a separate synchronous guide on the second pillar, on which usually no drive (especially for cost reasons) is provided, saved. The proposed arrangement ensures that tilting or tilting of the platform, in particular in the area of the first pedestal is avoided, since the constant overall length of the Ausgleichszugelementes, but the variable sections on the first or second pedestal (the length below the platform does not change ), the movement of the platform on the second pedestal (where usually also the motion drive is located) is transmitted to the movement of the platform on the first pedestal.

Since the first end is above the platform, in particular above the raised position of the platform, the compensating tension member receives at least a portion of the load on the platform and directs it directly into the pedestal. It is therefore convenient to arrange this bearing point on the side of the platform remote from the movement drive. The static concept is very simple in such a storage device, the production cost of a storage device according to the invention are low.

Due to the very good accessibility of the first end of Ausgleichszugelementes, which is conveniently always located above the platform, the connection points are provided here at the first pillar, which is achieved by a constant length of Ausgleichszugelementes (for example, as part of a larger lot equal length link chains) and different platform widths can be realized with the same pillars and also the same other elements of the drive. If a slightly wider platform is realized, then a lower connection point is to be chosen, with a slightly narrower platform, a connection point higher up is used.

It has already been mentioned that it is clever for the traction means in the area of the guidance of the platform to act on the second pedestal on the platform. The Ausgleichszugelement is used for synchronism of movement in the first pillar, where actually a traction device attacks only one side, is carried out by the proposal no tilting or wedging of the platforms on the two serving as guides pillars.

Therefore, it is also proposed that the second end of the Ausgleichszugelementes is connected to the second column in the lower region of the second pillar. The adjustability no longer plays a role here, since the good accessibility is provided on the first pillar.

Furthermore, it is proposed in a variant that along the pedestal a Verriegelungsrasterung is provided, in which a locking element of the locking device engages holding. Such an embodiment is simple but effective to implement.

Cleverly, it is further provided that the locking device is formed by a row of holes in the pedestal into which an actuable locking pawl engages. The arrangement is chosen so that the pawl, for example when pulling the platform from grid to grid, ie from hole to hole on the row of holes rises automatically, but in the event that a problem with the motion drive or a chain break occurs, the pawl firmly engages in the respective hole and holds the platform in the locked position. For a controlled lowering of course, the locking pawl is to operate accordingly, that is, retract, so that the locking function is canceled. This is done, for example, by a correspondingly monitored drive, for example an electromagnet which, without current, stretches the latch into the row of holes and retracts the latch only when energized. But there are also other concepts possible.

A further advantage lies in the fact that a standing pillar foot designed as a component independent of the pedestal pillar is provided on the pedestal. It is thereby achieved that the storage device for the construction on a variety of foundations, floor panels, substrates and so on is used variably, without having to hold the entire pedestal according to the different variants. Cleverly, a single or Mehrfachschraubverbindung is provided for the connection of the pedestal with the Standsäulenfuß to reliably dissipate the forces occurring in the pedestal in the foot.

There is a modular principle in this area. A pedestal which can be manufactured in larger lots can be connected with two or four different variants of pedestal base via the single or multiple screw connection, whereby skillfully the stability of the arrangement is increased by a positively locking in the assembled state of pedestal base and pedestal Interaction of pedestal and Stand column foot is provided. This is achieved by appropriate undercuts or recordings either on Standsäulenfuß and / or on the pedestal, through which appropriate Verwindung- or Verkippungskräfte not only via the screw but in addition by the positively cooperating elements from the pedestal are derived in the Standsäulenfuß.

Depending on the field of application, a substantially symmetrical or even asymmetrical structure of the pedestal base can be provided. A symmetrical design makes it possible to realize a relatively small-sized Ständeräulenfuß, which is then screwed for example by appropriate anchoring elements, such as screw anchors and so on in the bottom plate on which the storage device is constructed. As a result of an asymmetrical construction of the pedestal base foot, the longer area of the pedestal base being arranged in the direction of the drive-up area of the platform on the pedestal, a parking stand even under load can be realized. An additional anchoring on the ground is then no longer necessary. Of course it is possible to mix both variants mutatis mutandis.

Cleverly it is provided that the Ständeräulenfuß has mounting holes to durchzustecken fasteners such as screw anchors, screws, dowels and so on for attachment to the ground.

In a further embodiment it is provided that the two opposing, together the platform supporting pillars and the sliding pieces movable thereon are similar. In the design of the storage device care was taken with a minimum number of components all variants or a variety of variants but also application and use cases cover. Thus, the arrangement is particularly chosen so that the vertical columns, which face each other and are formed, for example, C-like, are of similar design. The same applies to the slidable on the pedestals sliding pieces that have to cooperate on one side with the working cylinder and on the other hand only have the carriage task. In this case, an arrangement has been found, as described for example in the drawing, which is very universally applicable, resulting in correspondingly large Losstücken and cost-effective production.

In Fig. 1 a storage device according to the invention is shown in an exemplary embodiment.

The storage device 1 consists essentially of two spaced-apart standing columns 3, 3 'on which the platform 2 is guided. For better guidance of the platform 2 on the uprights 3, the platform 2 has slide-like sliding pieces 25, 25 '.

As in Fig. 1 can be clearly seen, the height of the sliding pieces 25 is greater than the thickness of the platform 2. This results in a good guidance of the platform 2 on serving as guide rails pillars. 3

The platform 2 consists of a frame (not shown), which is bounded laterally by cheeks 29, 29 ', the platform bottom is covered with a plurality of parallel laid, panel-like segment profiles. According to the stability achieved by the segment profiles 28, it is possible to make the frame of the platform 2 easier.

For raising or lowering the platform 2 to the vertical columns 3, a movement drive 4 is provided. In the in Fig. 1 or in Fig. 2 In the embodiment shown, the movement drive 4 is preferably designed as a hydraulically acting working cylinder 43.

If the inventively provided working cylinder 43 is pressurized, the piston rod 40 is moved along the upward part of the double arrow 45. The movable rod 40 or piston rod 40 is therefore movable along the double arrow 45, a lowering movement takes place, for example, by a corresponding reduction in pressure.

An essential advantage of this concept for the motion drive is that with the single-acting, so not telescopically designed working cylinder a relatively high and over the entire height constant speed of movement of the platform when lifting or when discharging is achieved.

The movement drive 4 comprises a movable rod 40 at the upper end of a tension deflection 41 is provided for the traction means 42. The Zugumlenkung 41 is formed for example as a rotatable roller.

This in Fig. 1 . 2 shown principle of the movement drive 4 is derived from that of a simple cable. The arrangement has with the rotatable roller or Zugumlenkung 41 a moving through the movable rod 40 with the corresponding advantages of pulley. The traction means 42 has two ends, wherein one end is preferably connected to the platform 2 in the region of the sliding piece 25. As a result, the lifting force is impressed in the platform 2 to raise the platform 2 accordingly.

Starting from the platform 2, first the traction means 42 extends vertically upwards, in order then to be deflected in a semicircle via the tension deflection 41. At the other end, so the platform 2 remote from the end of the traction means 42, a length compensating piece 5 is provided. Also, the length compensating piece 5 is claimed as the traction means 42 to train. The length compensation piece 5 is then fixed in the embodiment shown here on the fixed part of the movement drive, for example, the fixed cylinder 44 of the working cylinder 43, but it can also be another fixed element on the storage device 1 or the storage device 1 receiving building.

In Fig. 1 but better still in Fig. 2 , the principle two-part construction of pedestal 3 and pedestal base 30 is shown. In the embodiment shown here a Mehrfachschraubverbindung 39, in this case a total of six screw connections per Standsäulenfuß 30 is provided to connect this with the pedestal 3.

Such a variant according to the invention makes it possible, as in a modular system, to provide arbitrarily designed pedestal columns / pedestal base combinations, wherein at the same time large batch sizes for the pedestal column 3 can be realized.

The particular advantages of the invention will be explained later.

In the Fig. 3 to 8 Different variants with different details of the pedestal 3 of the storage device 1 according to the invention are shown.

The embodiments shown here differ in particular with regard to the different design of a limiting device 7 for the movement length of the movable rod 40. Furthermore, the FIGS. 3 to 8 Various variants of a length adjustment 8 of the length compensation piece. 5

Since the structure of the pillar 3 in the Fig. 3 to 8 Incidentally, this is no longer referred to separately here. He corresponds to the structure as for example in Fig. 1 or 2 already explained.

In the Fig. 3 to 5 different embodiments of a limiting device 7 are each shown in combination with a respective constant length adjustment 8.

In the in Fig. 3 In the embodiment shown, the limiting device 7 is designed as a rod which has a stop 70 at its upper end, which then blocks the lowering movement (double arrow 45 downwards) of the movable rod 40 when the receptacle 46 of the tension guide 41 bears against the stop 70.

In the example shown here, as well as in the other examples, the lowering device or retraction movement of the movable rod 40 or piston rod 40 is often limited in its end point by the limiting device 7. Of course, it is possible to choose a different arrangement, namely that the upper end point of the movement is correspondingly limited by a stop. In principle, both variants (individually or jointly) are possible according to the invention.

The storage device 1 according to the invention is designed so that in the lower or retracted position of the movable rod 40 and the lowered position of the platform 2 corresponds. Depending on the position of the stop 70 then remains more or less space for lifting, that is, the resulting lifting height is adjusted by the position of the stopper 70.

The setup takes place in such a way that the platform 2 is initially in the lowered position. The traction means 42 is posted or at least the Längeneinstellvorrichtung 8 is opened so far, so that the movable rod can be raised accordingly, to the desired position of the lower end point, with completely lowered platform 2. This position is then the stop 70 calibrated accordingly and Traction means 42 again firmly mounted or the length adjustment device 8 stretched. For example, although another stop position for the stop 70 is now selected, the platform 2 is still in the lower position, the remaining travel of the movable rod leads to a corresponding lifting height of the platform 2.

This procedure is favorable in that the lower end point can be kept depressurized and thus no additional effort is required for securing.

It should be noted that the upper position of the platform 2, so in the raised position may not be secured only by the hydraulic drive, but additional mechanical security are provided to ensure a passive secure support of the raised platform 2 here.

The limiting device 7 is adjustable. For this purpose, the in Fig. 3 provided limiting rod 71 in the lower region a plurality of locking holes 72 which cooperate with corresponding counterparts to effect adjustment of the position of the stopper 70. In this case, the stop 70 is located on the end of the limiting rod 71 facing away from the locking bores 72. The position of the limiting rod 71 can, of course, be fixed again.

In Fig. 4 another variant of the present invention preferably arranged limiting device 7 is shown. The structure of the movement drive 4 is again basically similar to that in Fig. 3 , as a movement drive 4 here is a working cylinder 43 with a piston rod 40 as a movable rod. In the position shown here, the piston rod or movable rod 40 is completely lowered or lowered, the receptacle 46 rests on a package of several sleeves 73 and is fixed stop-wise in its other position. In this case, the uppermost sleeve 73 'acts. as a stop, since this comes into concrete contact with the receptacle 46 in the lowering movement of the movable rod 40. The sleeves 73, 73 'are attached to the rod.

According to the invention it is provided that either only a sleeve 73 or a kit (as in Fig. 4 shown) is used. Again, the procedure for mounting similar to Fig. 3 explained, of course, the sleeves 73 are preferably in two parts to avoid disassembly of the working cylinder for installation of the sleeves. The sleeves are then designed, for example, as half shells and correspondingly complete with a simple screw connection or clamping connection, can also be mounted or plugged onto the rod. Such an embodiment is of course also easy to install for the user and therefore also easy to use.

This in Fig. 5 shown realization example of the limiting device 7 is the in Fig. 3 relatively similar. Again, a limiting rod 71 is formed with a stop 70, wherein the stopper 70 cooperates with the underside of the receptacle 46 and forms the lower end point of the movement.

In this embodiment, a finer adjustment is shown. Finally, a continuous adjustment of the limiting device 7 is possible because the limiting rod 71 is formed as a threaded rod and can be fixed with one or more adjusting nuts 75 on the holder 74 in its axial position. The holder 74 also acts in this case as a receptacle for the length compensation piece 5. The limiting rod 71 is adjustable in the direction of movement of the rod 40.

As already explained, a change in the movement length of the movable rod 40 is accompanied by a corresponding change in the effective length of the traction means 42.

It should be noted that not the entire length of the traction means 42 is to be guided over the trained as a roller train deflection 41, but a certain part needs to have in any case no flexibility. This relatively rigid portion is summarized in the length compensating piece 5, which cleverly this length compensating piece 5 also has a length adjustment device 8 in order to reduce the effective length of the traction means 42 for adjustment purposes.

In the Fig. 3 to 5 or 6 to 8, two different variants are shown for this purpose, wherein in the variants of Fig. 6 to 8 the length adjustment device 8 are formed by a plurality of locking bores 80 which are fixedly connected to a holder 81 in the corresponding stages (corresponding distances between the locking bores 80). It is clear that the lifting forces are to be derived via this connection, which is why it depends on a sufficiently mechanically stable design.

In addition to this variant show the FIGS. 3 to 5 another possible variant of the length adjustment 8 of the length compensation piece 5. In this embodiment, an adjustment rod 82 is provided which is designed as a threaded rod and can be fixed with the corresponding adjusting nuts 83 on the bracket 81 in the desired height.

The traction means 42 connects in a connector 50 hingedly. This can be realized by a corresponding bolt fastening. The traction means 42 can be realized, for example, as a steel cable, rope, chain or the like. Optionally, it is provided that the connecting piece 50 about the longitudinal axis of the adjusting rod 82 is rotatable so as not to impose unnecessary torsion in the pulling means 42. The rotatable position can optionally be determined by a lock nut.

The invention is in no way limited with respect to the combination of the various limiting devices 7 and the different variants of the length adjustment device 8 of the length compensation piece 5. In this application, several variants are shown without wishing to give an exhaustive list. It should be noted that the limiting device 7 after Fig. 6 the of Fig. 3 , one after Fig. 7 the of Fig. 4 and those of Fig. 8 those after Fig. 5 equivalent.

In a preferred variant of the invention, it is provided that, seen in section, the pedestal is preferably formed from a C-shaped or U-shaped profile. Such a profile is characterized by a high static load capacity.

In Fig. 9 the storage device 1 according to the invention is shown schematically in use. On the raised platform 2 is a vehicle 19. Below the defined by the platform 2 first parking space 10 thus results in a second parking space 11 in which a vehicle, for example, needed for daily trips can be parked.

The platform 2 is held and guided by two standing columns 3 respectively arranged on the side. For lifting the platform 2 is the movement drive 4, which is provided on the right side, on the second pedestal 32. The movement drive 4 is, as for example in the Fig. 2 to 8 described, executed.

Two deflections 23, 24 are provided on the platform 2, wherein the left deflector 23 is located in the region of the first pedestal 31 and the right, second deflector 24 is in the area of the right, second pedestal 32.

The Ausgleichszugelement 20 is skilfully guided over the deflections and extends from its first end 21 (in the upper region of the left, first pillar 31) vertically downwards to the first deflection 23, then progressing in a horizontal direction below the platform 2 to to the second deflection 24 in the region of the second pedestal 32, from there again perpendicular to run down parallel to the pedestal 32 and to be stored at the second end 22.

It should be noted that the fulcrum of the roller designed as second deflection 24 is below the horizontally extending portion of the Ausgleichszugelementes 20, wohingehen the axis of rotation of the likewise designed as a rotatable roller, the first deflection 23 is above the Ausgleichszugelementes 20.

As in Fig. 9 shown, the Ausgleichszugelement 20 extends below the platform 2, without limiting thereto the invention. It is of course possible, the Ausgleichszugelement suitably housed on the top of the platform 2 or in the platform 2, so to arrange protected. All the above variants are part of the invention.

The operation of the storage device according to the invention is as follows.

First, the platform 2 is in the lowered position (in Fig. 9 not shown, better in here Fig. 1 ) to park the front platform end 27 on the ground so that a vehicle or other good can drive onto the platform.

The movement drive 4 is then activated, for example, the hydraulically acting working cylinder 43 is pressurized in such a way that the piston rod 40 is moved upwards. The movable rod 40 does not engage directly on the platform 2, but instead a separate traction means 42 is provided for this purpose.

It will be described how this traction means 42 is formed in a preferred manner.

The piston rod 40 carries at its upper end, held in a receptacle 46, the trained as a deflection pulley 41. The principle of the moving roller leads to a corresponding deflection of the traction means 42 with appropriate consequences, as they are known from the cable. The length of the traction means 42 is constant, the speed of the lifting platform 2 is twice as large as that of the ausschiebenden piston rod 40th

The traction means 42 engages the platform, preferably on the sliding piece 25 of the platform, as close as possible in the vicinity of the deflection 24, whereby possible tilting moments and so on are kept very low.

It is an object of the invention to provide a reliable drive with as little effort as possible for the motion drive, that is to say a drive which does not lead to jamming or tilting of the platforms loaded with up to 2.5 t or more. Tilting or tilting of the platform 2 is especially risked if the synchronous properties of the platform 2 at the two parallel arranged pillars 31, 32 are different. To avoid this, the Ausgleichszugelement 20 is provided. In this case, the load of the platform 2 is supported via the left-hand deflecting 23 on the compensating tension element 20 and is discharged via the first end in the left-hand first pedestal 31. At the right end of the platform, the tension element 42 engages directly on the platform and transfers the forces into the structure, here into the right, second pedestal 32.

The advantage of the Ausgleichszugelementes is in particular that it is a cost manufacturable element that is maintenance-free and reliable.

In Fig. 10 is the principle of the storage device 1 according to the invention Fig. 9 again shown schematically. Due to the flexibility of the Ausgleichszugelementes 20, which allows a corresponding articulated bend (double L-like, opposite to the respective deflections 23, 24) at each point, the synchronization properties of the platform 2 over the entire lifting height are guaranteed.

An essential aim of the present invention is the high variability of the storage device according to the invention, in order to realize advantages in the production costs by means of large batch sizes.

A parameter in stopping devices is the width of the platform 2. Due to the width of the platform 2, of course, the distance between the two vertical columns 31, 32 changed and thus the respective length of the Ausgleichszugelementes 20 changes.

Here, however, the invention proposes a new concept, which leads to the fact that a plurality of different width types of the storage device can be realized with a compensation tension element. This is for example in Fig. 11, 12th , or in addition thereto also in Fig. 3 or 1 shown.

Reference is made at this point to the connection points 300, which are arranged in the upper region, preferably the first pedestal 31. Of course, the connection points 300 can also be at the second Standing column 32, here preferably in the lower area, are provided.

It should be noted that cleverly the Ausgleichszugelement 20 ends in the region of the right, second pillar 32 in the lower region and next to this second pillar 32 and the movement drive 4 is provided.

Cleverly the Ausgleichszugelement 20 is posted on the pedestal below, at which also the traction means 42 connects to the platform.

The series of connection points 300 are in Fig. 11, 12th shown in an enlarged detail. The distance between the individual connection points 300 with one another corresponds to the distance between the different width variants of the platform 2.

In order to easily perform the width adjustment, the Ausgleichszugelement 20 has at its first end 21 a correspondingly equipped fitting 26, which can be introduced in a more appropriate manner in the connection point 300 and fixed there. Optionally, the connector 26 is held securely and firmly by a screw in the connection point 300.

Below the connection piece adjoins an adjustment range 200 for a fine length adjustment. Below there is a coupling piece 201 for an articulated connection with the Ausgleichszugelement 20th

In the embodiment shown here, the connection points 300 are realized in the upper region of the pedestal 31, but according to the invention it is also possible that the connection points 300 are also provided in the lower region of the pedestal 3, for example on the second pedestal 32. Of course, the arrangement is in the upper Area for mounting purposes cheaper. Basically, both variants can also be combined with each other.

In Fig. 13, 14th Two different variants of the pillar base 30 according to the invention are shown.

The invention is characterized in that also by a high variability in the design of the Standsäulenfußes 30 with otherwise the same structure of the pedestal 3. Instead of the otherwise known one-piece design of Standsäulenfußes 30 with the pedestal 3 is now proposed according to the invention that the Standsäulenfuß 30 is designed as a separate, separate component and is selected according to the specific requirements, then connected to an otherwise producible in large numbers stand column 3 to become.

For stable, statically resilient connection of the pedestal 3 with the Standsäulenfuß 30 a single or as shown here Mehrfachverschraubung 39 vorgesehen. Is provided.

It is clear that over this connection, the entire load of the arrangement is derived with the vehicle up and here is to achieve a corresponding stability.

In Fig. 13, 14th Two different variants are shown, in Fig. 13 an asymmetrical shape of the Ständeräulenfußes 30 is shown, wherein the right part 33 of the Ständeräulenfußes 30 is significantly longer than the left part 34. Of course, this results in a higher stability, since the footprint of the stand 30 is greater than for example in the variant according to Fig. 14 , In this case, the right part 33 extends in the direction of the front end 27 of the platform 2 is passable.

Due to the increased footprint according to the variant according to Fig. 13 If such a standing pillar 3 or parking device 1 is suitable to be set up with minimal additional installation or anchoring effort. Of course, this is useful if the ground is created accordingly.

In the in Fig. 14 shown second variant, a symmetrical Standsäulenfuß 30 is proposed, the footprint is smaller than the variant according to Fig. 13 and preferably with additional anchoring means, for example, ground anchors, screw anchors, screw-dowel combinations and so on to attach to the foundation or the bottom plate. Of course, a symmetrical foot can also be realized larger than the suggestion Fig. 13 ,

In Fig. 15 this is shown schematically again, the Ständeräulenfuß 30 is formed substantially in view L-like, wherein the upstanding leg has the openings (holes) for the screw 39. Accordingly, the pedestal has 3 cooperating openings 39 'for inserting the screws or other connection means

In order to produce a stable connection between the pedestal 3 and the Standsäulenfuß 30, an arrangement is additionally chosen to avoid twisting as possible. This is achieved by a positive cooperation of the pedestal 3 with the Standsäulenfuß 30, for which purpose the pedestal 3 in the lower region has a projection or shoulder 38 which can be inserted into corresponding slots 37 in the horizontally extending legs of Standsäulenfußes 30. Furthermore, attachment openings 301 for anchoring elements and the like are also provided on this leg.

Another interlocking interaction is effected by the umgebörtelten edge 36 in the central region of the Ständeräulenfußes 30, which is formed positively engaging in a corresponding recess 35 in the lower region of the pedestal 3.

Furthermore, the invention also includes a link chain, which is used in particular for a parking device for motor vehicles as described. It should be noted that this articulated chain is not only distinguished for this particular application, but is also to protect itself independently and the Applicant intends this. The articulated chain described below finds use in the above-described parking device as traction means cooperating with the movement drive and / or as compensation element running below or on the platform and ending on the pedestal.

The joint chain 6 according to the invention is in the view in Fig. 16 shown.

FIGS. 17 and 18 each show in a plan view two different variants of this hinge chain 6 according to the invention.

In this case, the link chain 6 consists of a plurality of chain links 60, 60 ', which are each connected by bolts 61 to each other articulated.

The individual chain links 60 consist of a plurality of tabs 62 arranged parallel to one another, wherein the tabs 62 are preferably identical to each other.

To increase the stability of the joint chain according to the invention, the tabs are arranged twice as double tabs, as for example in Fig. 18 can be clearly seen in the region of the end chain link 63. There are just two identical tabs 62nd arranged side by side over the entire surface, these two tabs 62 belonging to the same chain link 60.

For connection purposes of the articulated chain, the tabs 64 of the end chain link 63 are formed larger or longer than the tabs 62 of the remaining chain links 60th

The difference between the variant after Fig. 18 and the variant Fig. 17 is that in Fig. 17 eight tabs 62 (four double tabs) per chain link 60 and at Fig. 18 six tabs (three double tabs) are provided.

In addition to a division of the six tabs per chain link in three double tabs, of course, the variant is realized that centrally two double tabs are provided, which are covered on the outside by a respective outer tab. In the variant with eight tabs then three double tabs are arranged in the middle, which are each covered by a simple outer flap.

The joint chain 6 according to the invention shown here, which is also referred to as a flyer chain, is characterized by a very high breaking strength with a small thickness and small pitch (spacing of the bolts 61).

Preferably, it has been provided according to the invention that the pitch of the chain links is 14 mm to 17 mm. In particular, an interval of 15.6 mm to 16 mm is provided in the in FIGS. 16, 17 and 18 In the embodiments shown, the pitch is approximately 15.87 mm.

The thickness of the joint chain is preferably at least 11 mm, particularly preferably 12 mm to 18 mm. In the in Fig. 18 shown embodiment, the thickness d of the articulated chain is about 15 mm or 15.1 mm.

According to the invention it has been found that it is favorable that the ratio of width of the chain to the thickness of the chain is less than 3, in particular a ratio of 1.9 to 2.8 is proposed. Such a chain is characterized by high stability, that is, high tensile forces at the same time small dimensions and small Abwinkelradien. The width of the chain varies, for example, from about 28 to about 42 mm.

A bolt diameter or a bolt thickness of at least 4.5 mm is preferred. Preference is given to 5 mm to 7 mm, particularly preferably 5.8 mm to 6.2 mm proposed in Fig. 17, 18 shown bolts have a diameter of about 5.95 mm.

So-formed hinge or leaf chains have a breaking load of at least 100 kN (according to the embodiment of FIG Fig. 18 ) or at least 156 kN for the embodiment according to Fig. 17 , at a width of the articulated chain of only about 31.5 mm ( Fig. 18 ), or approx. 41.1 mm ( Fig. 17 ).

In the Fig. 19 The arrangement shown corresponds largely to that of Fig. 1 only with the difference that here two shut-off devices 1a and 1b are arranged side by side. The movement drives 4a, 4b of the two shut-off devices 1a, 1b are located in the middle "back to back". This figure shows the high flexibility of the construction and manufacture, since it is immaterial according to the configuration of the columns 3a, 3b or the sliding pieces 25a, 25b, whether the movement drive is arranged on a platform or storage device on the left or on the right column. So it is easily possible to adapt the storage device according to the invention, for example, for left or right-hand drive vehicles, the whole takes place without additional components.

Furthermore, the invention with respect to the arrangement of the movement drive 4, 4a, 4b in front of or behind the column 3, 3a, 3b (relative to the retraction direction 202) free. In the variant after Fig. 1 is the movement drive 4 in this regard arranged on the back of the pedestal 3, in the variant according to Fig. 19 before. The movement drive 4, in particular the working cylinder 43, is thus provided between the entrance area 202 of the platform 2 and the pedestal 3.

In Fig. 20 the combination of the pedestal 3 with the pedestal base 30 is shown. In the example shown here, it should be pointed out in particular that both the movement drive 4, realized by the working cylinder 43, and the length compensation piece 5, realized by the turnbuckle 51, are supported on the horizontally extending part of the L-shaped standing pillar base. If necessary, a corresponding reinforcing plate is arranged, a minimum distance between these two elements reduces the occurrence of bending moments, the minimum distance results from the respective width of these components.

In a preferred variant of the invention it is provided that the limiting device 7 is indicated by the self-locking of the working cylinder 43. On a separate arrangement of a limiting device 7, it comes as in Fig. 20 shown, not on, this is achieved by an appropriate dimensioning of the working cylinder.

Fig. 21 shows in the detail circle XXII, where the locking device 9 is basically arranged, this is in Fig. 22a . 22b explained in more detail. In the pillar 3 (compare also Fig. 20 ), a locking catch 90 is provided.

This locking catch extends over a wide range of height of the pedestal. 3

In Fig. 22a is the locking catch 90 also noted, which is realized here by a row of holes 92. In the in Fig. 22a As shown locking position 91 formed locking element is retracted by the push rod 93 such that the front portion 94 does not engage in the hole 92. In this position, the push rod 93 and the pawl 91, which is rotatably mounted about a horizontal axis 95, the platform 2 can be lowered. The position of the push rod shown here is achieved by an energized magnet.

In Fig. 22b the lock case is shown. The push rod 93 is offset to the left, such that the front portion 94 of the pawl 91 is in the hole 92 and a lowering movement at the edge 96 prevents (the magnet is de-energized, the lock engages!). Thus, the locking position is defined, a correspondingly solid support bracket 97 holds the locking pawl 91 in the locking position, since the pawl 91 abuts against the angle 97.
