Description

description

The invention relates to a revolving gate with the features of the umbrella term of claim 1.

Such gates are primarily intended for the closure of courtyard entrances and should take into account the given structural and traffic-related conditions on the one hand fully correspond and on the other hand be inexpensive to manufacture.

The structural conditions are very different and then difficult if only a limited space is available for the movement of the gate or the open position of the sash obstructs access or passage.

With regard to the traffic situation is between homogeneous Traffic, vehicles or people, and mixed traffic with each different Differentiating between interests.

For doors with a motor drive, especially those with remote control without visual contact, numerous safety regulations must also be observed, which increase the construction costs considerably. Manual emergency operation must be possible.

In addition, there are architectural requirements, especially the design affect the formwork and require time-consuming individual production.

The known motorized swing gates differ mainly regarding the type of drive.

DE-GbmS 79 06 466.7 discloses a revolving gate, the wing of which is from a drive lever pivoting about a vertical axis is actuated, which is shown in engages a guide rail attached to the wing.

DE-GmbH 79 07 558 describes a swing gate with a telescopic Acting drive that is self-locking at least in the open position of the gate leaf held wid. Similar designs based on the hydraulic principle are widespread.

The end positions of the sash are mostly determined by the drive unit determined or it is driven against stops. The lock in the closed position due to the frictional connection of the drive, in particular due to the large leverage with wide wings, high reaction forces. It is therefore often on the Opposite closing edge an electromagnetically operated bolt is required, which is in front of at the beginning of the opening movement of the sash is switched on by the drive control will. The individual installation of such a bolt and the laying of the However, control lines are complex.

The most decisive cost factor is the drive unit, which is usually the case more expensive than the wing is included in the calculation. A double-leaf swing gate costs therefore around twice as much as a single-leaf gate of the same width. on the other hand wide gates require a correspondingly large swivel space and longer travel times. In addition, they are unwieldy for people to pass through.

Another problem arises from the control of motor-driven ones Entrance gates in mixed traffic. Although the (trunk) users using the driveway are Vehicles equipped with transmitters, but not pedestrians and cyclists. It surrendered thus two conflicting interests arise. The vehicle driver wants an automatic The gate to be operated is as wide as possible and the pedestrians (think to a residential building for several families with children) the unproblematic manual operable small revolving door. If such a revolving door is installed in addition to the gate, then their width is no longer available for the vehicle entrance. The vehicle must then, assuming the usual space conditions, with regard to the turning circle be steered before entering the opposite lane.

The optimal use of the structurally feasible entry width is of interest even on roads with heavy stationary traffic.

Most of the time, the driveway is kept free, but parked across from it. In such cases, the width of the passenger wing is particularly important to be able to use for the Pahrverkehr.

The industrial (inexpensive) production of swing gates sets a As high as possible partial equality ahead, so that these in economic numbers can be manufactured.

The invention is based on the object of the revolving gate with a motor Further develop the drive so that it takes into account the safety regulations meets the requirements of mixed traffic, with only one drive unit even with larger widths, can be installed even with limited swivel space can and is inexpensive to manufacture with individual formwork.

voruasHieise This object is achieved according to the invention by GaRYim Area under the face of the (main) wing, a stationary holding part is arranged is, in which, in the closed position of the gate, a fixing element moved with the wing releasably engages, which is mechanically connected to the drive via connecting means or that is equipped with electrical or hydraulic movement elements which are controlled by the drive device.

This gives the sash a stable stop in the closed position at the level of the front side, which is independent of the stationary, vertical counter-closing edge is.

This fixation makes it possible that in the area of the front side of the main wing a second wing rotatable about a vertical axis II or slidable in guides is arranged, which in its mobility or its movement from the drive of the Sash directly mechanically or indirectly electrically or hydraulically or in combination is controlled.

The agility control includes manual handling of the Wing with simultaneous motorized actuation. The movement of the second leaf by the drive of the main leaf saves the 2nd drive.

The open position of the sash must also be guaranteed in the event of a storm, whereby in unfavorable cases purely force-locking fixing devices are not sufficient. A further holding part is therefore assigned to the fixing element in the open position.

According to the invention, the driving forces are generated via a one on the main wing arranged force transmitter initiated, which has a part moved by the drive, that via lanyards with is connected to the fixing element. This enables the end position locking with simple mechanical components and regardless of the structural conditions.

For a preferred embodiment of the force introduction into the wing provided that a force transmitter is arranged on the main wing, which consists of a There is a backdrop in which a power arm is guided. Since the axis of rotation I of the main wing and those of the power arm are offset in parallel, moves when opening or when Closing a part attached to the power arm, e.g.

a role along the backdrop. This movement is used to control the Fixation in the end positions, to control the mobility of the second sash and to Movement of the second wing used.

With a rocker-like mounting of the backdrop and its coupling The functional link to the connecting means of the fixing element is achieved the end position locking with the rotary movement. When opening the power arm presses first the gate from its closed position Z to the open position A and releases thus the fixation of the closed position. In the course of the rotary movement, the Role of the power arm the center position of the backdrop and rotates it in reverse Sense of direction. The fixing element can thus be in one of the open positions Hold part into place. This additional pixel ensures that during storms or other disruptive forces the open position is secured.

The closing process is analogous in reverse order.

The same effect can be achieved with a firmly connected to the wing A backdrop in which the moving organs are located, which are coupled with the connecting means are.

Instead of being used as a backdrop, the power transmitter can also be used as a lever mechanism train to which the connecting means is connected.

According to the invention, the second wing can be like a conventional one Revolving door operate and also lock. This becomes functional with the lock Associated lock causes that holds the secondary sash in the closed position. Presses If you pull the doorknob, the lock is activated by means of connecting means (e.g.

a linkage) and the second wing can be rotated around the axis of rotation II move. When the lock is locked, the latch is blocked. The motor operation and manual operation, however, must be mutually exclusive.

For this purpose, according to the invention, the lock is equipped with a blocking element, the release of the fixing element from the stationary holding part when the pawl is actuated prevented.

If you switch on the drive in this situation, it will through its overload device switched off again immediately.

An alternative or additional option is provided by electrical contacts, which are operated by the lock of the lock or parts, their location from the position from the main wing to the secondary wing. The thus controlled circuit prevents the start of the motor when the secondary leaf is not closed.

So that the second wing is not open due to negligence f ~ or door closer ~ ~~.

remains, a spring is provided that pulls it back into the closed position.

In the event of a drive failure or a power failure, the secondary leaf remains operational anyway; the opening or closing of the main wing depends on the Drive type from. On the door side, it is provided that, for example, one when open Second wing accessible opening the fixing element can be operated by hand. It is advantageous to design the fixing element as a vertically arranged rod.

This rod is robust and heavy enough to hold the lanyard to be pulled into the end position without additional spring force.

The two leaves must be aligned with sufficient accuracy in the closed position, because the eye of critical customers easily recognizes misalignments. A preferably adjustable one The stop therefore limits the closed position of the second sash.

According to the invention, the frames of the wings are generally made of tubes manufactured, which enclose the connecting means. This means that they are weatherproof housed and at the same time withdrawn from unauthorized access. With differently designed Sash, separate profiles are applied to the outside of the sash.

In the design described so far, the second sash moves with the motor Drive in closed position with the main leaf with. Another variant provides that the second wing is connected to the power transmission via a power train. The drive of the secondary wing is thus derived inexpensively from that of the main wing. This is preferably done with a pulling device, e.g. a round bar, and several Articulated rods that are supported on stops. The relative movement of the secondary wing to the main wing is effected by spring force.

However, this movement is controlled by the power train so that the end face of the second wing is the closing level of the wing, which can be the property boundary, does not exceed. The movement in the closing direction is positive; the Springs are tensioned again in the process.

There is an additional fixing element with a holding part for the closed position the secondary sash the necessary stability against horizontally acting forces. This fixing element is at least in the closed position with that of the main wing via connecting means coupled.

The secondary sash with its vertical main closing edge is designed in such a way that that it has a continuous free space to the stationary counter-closing edge. In order to there are no clamping effects due to thermal expansion or changes in inclination (caused by frost). This free space can be dimensioned so that it is the safety distance for fingers enough. In addition, there is no need for expensive electromagnetic locking devices in the area of the opposing closing edge.

The sash frame or sashes consist of tubes, the frame corners of which are on the inside are reinforced with perforated corner pieces. The perforation is used to attach more variably horizontal and / or vertical screw bases of the formwork. This makes it possible individually designed formwork fields corresponding to the fencing to hang in or to remove for later coats of paint.

Diagonal bars are provided to absorb the diagonal tensile load, which connect the corner parts lying in the direction of the tensile load. One of those built frame is easy to manufacture, due to the tubes sufficiently torsionally stiff, Rigid due to the diagonal bars, offers space for internal fasteners and the possibility of variable formwork.

An essential feature of the present invention is the high degree of equality of parts with all variants of the gate family.

In the following, embodiments of the invention are based on Drawings described in more detail.

They show: FIG. 1 a view of the gate in the variant with a manually operated one Second leaf in the closed position Figure 2 is a plan view of the door according to Figure 1 Figure 3 shows a longitudinal section of the side view through the lower casement Figure 4 shows a plan view of FIG. 3; FIG. 5 shows a cross section of the lower frame in the area of a force transmitter in rocker design; FIG. 6 shows a longitudinal section through a second wing for manual actuation, FIG. 7 shows a plan view of FIG. 6, FIG. 8 shows a detailed cross-section FIG. 6 FIG. 9 a view of the door in the variant with a motor-driven one Second leaf, FIG. 10, a top view of the door according to FIG. 9, FIG. 11, a longitudinal section in plan view of the power train Figure 12 construction variants of various components In FIG. 1 shows the main wing 2 with the secondary wing 3 in the closed position see. The main pivot bearings 28 form the axis of rotation I. They are at a fixed location Item 29 attached. The secondary rotary bearings 38 form the axis of rotation II around that of the Second wing 3 swivels. The drive unit 1 drives the power arm 16, which in the force transmitter 12 engages. The frames of both wings are made of tubes 21 or 31 composed in a rectangular shape. In the holding part embedded in the roadway 41 the fixing element 42 engages. The lock 51 is on the front side on the second wing 3 attached inside. If there is only one wing, then it is in the Position 51 '.

The formwork to be hung on the corner parts 26 was for the sake of clarity not drawn for the sake of

Figure 2 shows the door of Figure 1 in plan view.

A preferred embodiment of the fixing element can be seen from FIG 42, whose drive is anchored via the connecting means 45 and is anchored in the roadway Holding part 41. When the movement begins, the fixing element 42 is secured by means of the connecting means 45 (a linkage with deflection) lifted out of the holding part 41. In manual mode this unlocking takes place via the pawl of the lock 51 ', which jch only in the unlocked State is possible.

FIG. 4, a schematic representation of the force transmitter 12 in longitudinal section, explains how it works.

The power arm 16 presses on its roller 15 at the start of movement the rocker-like mounted gate 14 and thus first actuates the connecting means 45, which unlocks the wing. Then the backdrop 14 hits its end position and transmits the drive force to the main wing 2.

As the rotary movement progresses, the roller 15 moves in the backdrop along and swivels it towards the end of the rotary movement in the opposite direction of rotation. The fixing element 42 thus moves into the closed position and can be in the open position of the wing 2 snap into the holding part 41 '.

When closing, this process is reversed away.

Figure 5 shows the force transmitter in cross section at the level of the roller 15th

FIG. 6 illustrates the design of the second wing in a longitudinal section 3 in the version for manual operation in a schematic representation.

In the closed position, the secondary leaf 3 is locked by the lock 53 held, which can be released via the lock 51 and connecting means 45 '. Of the Release 54 prevents unauthorized squeezing of the lock 53 in the closed position. When the second wing is opened, the blocking element 56 remains, which is already in place has pushed over the fixing element when operating the lock, in the blocking position. The fixing element 42 can thus no longer be lifted out of the holding part 41 by a motor will. The drive unit provided for this purpose then switches via a force balance away.

The same effect is achieved with the contact 57 resulting from the opening movement the lock 53 derives a signal that prevents the drive from starting.

The relatively weakly dimensioned spring 55 pulls the opened secondary wing 3, if you let go of it, back into the closed position. Otherwise it would be motor Drive hampered by the negligence of passers-by. The adjustable stop 59, which is preferably designed to be elastic, defines the closed position of the second sash 3 to main wing 2.

FIG. 7 shows a plan view in longitudinal section through the upper one Frame tube the arrangement of the lock to the secondary pivot bearing 38 with the axis of rotation II. The second leaf 3 opens inwards in manual mode.

In FIG. 8, a cross-sectional detail of FIG. 6 is schematized to recognize the release 54 with its locking effect in the closed position.

Figure 9 describes the revolving gate in the version with a motorized movement Second wing in the view.

The power train 6 described in FIG. 11 is via a transmission 62 connected to the wing 3. When opening the fixing elements 42 and 42 'through the interconnected connecting means 45 and 45' from the holding parts 41 and 41 ″. The main wing 2 then pivots driven by the power arm 16 in its closed position SL. The spring 63, designed here as a torsion spring, rotates the secondary wing 3, supported by its inertia, clockwise around 1800 to the main wing 2. This rotary movement is controlled by the power train 6, the closing edge of the Second wing 3 roughly follows the path marked SK. This path remains within the closed position; the secondary wing 3 therefore does not run over the in any movement phase Property line.

In the closed position, the wings are parallel to each other and need therefore only about half the swivel space of a single-leaf gate of the same width. The closing movement runs in the opposite direction on the same tracks. Of the The power train pulls the secondary sash depending on the angle of rotation of the main sash 2 back into its closed position, thereby tensioning the spring 63.

In emergency manual operation after disengaging the drive 1 with the Lock 51 'unlocked and the main wing 2 opened. The second wing follows this Movement as with motorized drive.

This version is for vehicles with larger entry widths and / or limited pivoting space provided. For additional passenger passage Instead of the opposing closing edge 58, a further one that can be rotated about a fixed axis can be used Wing 72 are installed, which in turn consists of the same components.

FIG. 10 shows the door described with FIG. 9 in a top view.

The further wing 72 can also be #, analogously to that shown in FIG Type of construction that can be arranged on the second wing 3 to move with light formwork.

Figure 11 shows a schematic longitudinal section of the power train 6 and the gear 62 above in the open position and down in the Closing position of the wings. The traction means 61 1 'connects the roller pin of the power arm 16 with the gear, which is designed here as a joint polygon. It consists of the rods 64, on the one hand on the wing lever 68, on the other hand on the straight guide 66 are stored. At least one stop 65 enables the closing edge path to be corrected SK. The cover 67 protects the power train from damage and the weather.

The invention is not limited to those shown here Working examples.

For example, it is possible to design the second wing 3 as a sliding gate, which, according to FIG. 12a, is mounted longitudinally displaceably with guides 25 on the main wing 2 is.

The intended use corresponds to that of Figures 1 and 2 with almost same components for actuating the lock on the lock.

It is also possible, see FIG. 12b, the straight guidance of the backdrop 14 to be exchanged by a lever mechanism 18 to which the connecting means 45 or the Traction means 61 are articulated.

Instead of a power arm 16 that rotates about a vertical axis also a telescopic shortening movement element (e.g. a hydraulic Stamp) 17 can be installed.

It is also possible to use the power arm 16 or the drive 1 according to FIG 12c to be installed above. In the case of gates for house passages - the holding part 41, in the the fixing element 42 engages, be attached to the ceiling.

It is also possible to close the joint rods 64 by means of a cam replace, over which the traction mechanism 61 is guided.

It is also possible to rigidly attach the backdrop 14 to the wing 2 and to build in it movable members 44 which operate the connecting means 45 (Figure 12d).
