The first locking element has a slot (112) and the associated thrust bearing device has an engaging element for engaging in this slot, or vice versa. The slot narrows in the direction of the lock and the engaging element has a head (122) for engaging behind a wall defining the narrow region (115). The engaging element and the slot are arranged so that during movement of the door leaf out of its open position into a closed position and when the first locking element is in the unlocked position the head is introduced into the wide region (114) and on movement of the locking element out of the unlocked position into the locked position the head is moved into its engaging position in the narrow region. An independent claim is also included for a door, especially a garage door, comprising the above door-locking device.

Description

The invention relates to gate locking devices according to the preamble of appended claim 1 and with such a gate locking device provided gate, especially garage door.

Examples of such gate locking devices can be found in DE 296 17 597 U1 as well as many single-leaf overhead doors sold by the applicant. This Gate locking devices have been in the previous normal version manually operated lock with outer and inner handle and a square pin as Handle shaft, which engages in a square nut in the lock. The outer handle is formed by a knob and the inner one by a knob. The distance between the handles is to adapt to different door leaf thicknesses (sheet metal, wood etc.) adjustable in length. One is on for length adjustment and for the respective locking provided for the square pin attacking screw connection. On both sides of the Lock protrude as part of a motion transmission device for transmitting the Rotary movement of the handles in a translational motion from the deadbolt when turning of the square pin - closing and opening process - extend and retract. To the The square nut is inside the Lock housing provided with two flanges that can be moved on the driving pins of the engage the latch. Locking rods are on the drive bolts connected to the laterally arranged locking elements - mostly spring-loaded Snap or similar locking elements - and lead them to the lock to open them drag. The locking elements or locking elements are on the sides, mostly in the lower ones Side end areas of the door leaf attached and thus reach behind closing space facing mirror side of the side frames. This is how they work Side frames themselves as counter bearing devices for the locking elements.

The known gate locking devices can be manufactured quite inexpensively, offer little resistance to a break-in. For example, that in particular door leaf made of sheet metal in the area around the lock cylinder be pierced, which means that one inside the lock housing and one at the Inside of the lock existing slide for opening and closing the The lock. Such a slide is in the known locks provided to lock the lock from the inside of the garage by hand to be able to block. In addition to being attacked in the castle area, attempts to break in are frequent also on the locking elements - e.g. performed on the catches. To the Pry up the known gates, it is enough to attack the frame between this and to open a gap in the door leaf until the catches leave the frame attack. On the other hand, catches can easily pass through a gap be pushed into the open position against their spring force.

Attempts have already been made to increase security against burglary by increasing the number of Latch elements - such as locking links, catches or the like - and in particular by To increase locking on the upper horizontal frame area. But it has been shown that locking at the upper horizontal frame area is particularly dangerous is because there is a gap between the upper edge of the door leaf and the frame easiest or most feasible.

The object of the invention is to provide a gate locking device in the preamble of attached claim 1 specified type with the lowest possible cost in terms of Improve security against break-ins.

This task is accomplished by a gate locking device with the features of attached claim 1 solved.

Advantageous embodiments of the invention are specified in the subclaims.

To make locking elements that are particularly at risk more secure in a cost-effective manner, is according to the invention in a gate locking device, in particular for a Single-leaf overhead door, with a movement transmission device having at least one locking rod for transferring one for locking or unlocking rotary movement to be performed, in particular by locking a lock lockable handle in a translational movement of at least one Door leaf edge for engaging with a frame or the edge of the door opening proposed locking element proposed to be arranged locking element, that the locking element, in particular on the upper horizontal edge of the door leaf is arranged in the rotary movement of the handle to be carried out for locking from an extended unlocking position to the lock in a retracted position Locking position is pulled that this locking element has an elongated opening and the associated counter bearing device an engaging element for engaging in it Has opening - or vice versa, the locking element, the engaging element and associated counter-bearing device has the elongated opening -, the elongated Opening in the direction of movement from a wide area to a narrow area narrowed and the engaging element a head to reach behind the narrow area has and wherein the engaging element and the opening are arranged such that the Head when the door leaf moves from its open to the closed position and at Unlocking located locking element is insertable in the wide range and by moving the locking element from the unlocking position into the locking position got into the narrow area. In this embodiment of the invention, the in particular for locking elements arranged at the top on the horizontal edge of the door leaf is thought - whereby, of course, lateral locking elements can also be arranged can - the locking element for locking is not extended but retracted. It thus comes from the area of the upper gate gap. The locking itself then takes place about engagement between opening and engagement element.

A preferred embodiment relates to such a gate locking device, in particular for a one-leaf overhead door, with at least two locking bars having motion transmission device for transmitting one for the Ver or Unlocking rotary movement to be performed preferably by locking a Lockable lockable handle in a translational movement of at least two Door leaf edge for engagement with each on the frame or the edges of the Bolt elements to be arranged in the gate opening provided counter support devices, wherein the movement transmission device is on the inside of the door leaf section the handle shaft - at least in manual operation - for joint rotation with it clip-on or attachable disc element with at least one first and one second connection or take-along device for connecting the ends of the locking rods on the lock side with a radial distance from the axis of rotation of the Disc element on the same that the locking rods when turning the Disc element with a component tangential to this rotation translational is moved.

In the aforementioned advantageous embodiment, the locking rods are not as in the prior art by means of drive bolts, but by means of a disk element - that is a kind of traction sheave - driven. This is on the handle shaft, e.g. e.g. a square pin, attachable or attachable. Especially with manual ones Operation then turns the traction sheave together with the handle or handles. The Disc element is thus designed so that it can rotate with the handle shaft and can be driven by it in manual operation, e.g. via direct square engagement. On the other hand, the can also for automatic operation via a door operator Possibility of optional decoupling may be provided. With one Disc element is a general increase in stroke for the locking rods and thus also possible for the locking elements or similar locking elements. At the same time with one such disk element the connection of different numbers and different locking rods to be arranged and therefore very different Bolt elements possible. The locking elements no longer only have to be on the side of the door leaf edge be arranged, there are also arrangements on the upper and lower edge of the door leaf conceivable. The disc element can be centrally round and many connection options offer for locking or locking bars. The connection options are through created at least a first and a second connection or take-along device, which are arranged on the disc element such that the locking rods at Rotation can be moved tangentially - i.e. pulled or pressed -.

A particular advantage of the advantageous disc element is its Retrofitting. For this purpose, the disk element is preferably not in the lock housing housed, but outside of it and is located from the lock housing seen further inside in the room to be locked. This is preferably Disc element arranged between the lock housing and the inner handle. this has also the advantage that the traction sheave is designed with a correspondingly large radius can be. Due to the radial distance between the connection or driving devices The respective stroke of the locking element connected to it can be selected as the axis of rotation. In particular, a particularly large stroke of one at the end at risk can thus be achieved horizontal edge arranged locking element can be created.

A preferred embodiment is characterized by an - in particular, several millimeters thick - solid metal or the like resistant Material-formed protective shield for - preferably - being attached from the inside on the outside of the door leaf above the lock area. In addition to the Securing the locking elements provided additional measures the lock area protected. Both measures together result in a particularly burglar-proof gate, without significantly increasing costs.

In order to securely attach the protective shield and further strengthen the lock area preferably a counter plate is provided, which is fixed on the protective shield for placement and protruding from the outside inaccessible towards the inside, with screw threads, Splint grooves or pin holes or other offering a positive attack Attack training provided fastening bolts with appropriate Location holes is provided. This counter plate is therefore fixed with its holes and not accessible from the outside on the steel plate, holding the door leaf in between placed. In addition, the counter plate can be used as on-site holes Serve stencil. This is especially true when retrofitting an existing one or built-in gate with the gate locking device according to the invention very much helpful. By combining the protective shield, which is made of steel in particular and the counter plate is a widening or fraying of openings in the lock area making access through such openings much more difficult.

According to a preferred embodiment, the lock itself can be attached to the Fastening bolt of the protective shield with between the lock and the door leaf inserted counter plate.

To beautify the optics and / or to confuse burglars or others The protective shield can be difficult to access due to a cover be hidden. In a preferred embodiment, the cover comprises a convertible top sign that is placed over the outer surface of the protective shield. This is preferred Hood attached directly to the protective shield, especially via a Snap device clipped to the same.

In the embodiment with the disc element attached to the handle shaft it is particularly advantageous that different strokes can be generated. To in particular to design a locking element arranged in the upper door leaf area particularly securely is accordingly provided according to a preferred embodiment that the first and the second connecting or driving device has a different radial distance from Have axis of rotation of the disc element, in particular those for connecting a first locking element to be arranged on the upper horizontal edge of the door leaf first connecting or driving device has a greater radial distance than that second or further ones, in particular for connecting lateral and / or lower ones Locking element serving connection or driving device. To do this accomplish without the disc element in its dimensions or unwieldy To waste material is according to another preferred Embodiment provided that the disc element protrudes radially Has attachment area for attacking the first connection or driver device.

The disc element further preferably has an arcuate or annular plane Area on which one or preferably several - in particular the second or the second - attack connecting or driving devices and / or are trained. The disc element has a central, for placement on the handle shaft flat, in particular circular, area with an attachment opening with which the Disc element is placed on the handle shaft.

According to an embodiment intended primarily for manual operation only the top opening is designed for positive engagement with the handle shaft. Is the Handle shaft formed for example by a square pin, so the Attachment opening can be designed as a square opening.

It is particularly advantageous if a gate initially intended only for manual operation can later be retrofitted for automatic operation. This is after a particularly advantageous embodiment of the invention provided that the Gate locking device either for manual operation or for using a for transferring the door from the open to the closed position and vice versa suitable door drive automatic operation is adjustable. this happens preferably by a coupling device, by means of which the disk element for joint rotation with the handle shaft can optionally be coupled for manual operation or, if automatic operation is desired, can be decoupled for free rotation. In the decoupled state, the disc element can freely on the handle shaft turn, the handles can then affect the through the Locking elements to be driven are locked. This is possible because door drives are usually designed in a self-locking manner are, so that under certain circumstances no additional locking is necessary. The Disk element is preferably freely rotatable on the handle shaft, wherein the coupling device for coupling the disc element to the handle shaft form-fitting with both the handle shaft and the disc element in Intervention can be brought. For this purpose, the gate locking device according to the invention is shown in FIG preferred embodiment formed such that the coupling device in particular a coupling element which can be plugged into the handle shaft in a form-fitting manner with at least one engagement element - in particular a driver pin - that for coupling the disc element to the handle shaft with the Disc element can be brought into engagement. The coupling element is preferably with provided with a through opening. The through opening is designed such that the coupling element can be placed on the handle shaft, optionally rotated by 180 °. The coupling element also has a radially projecting flange region, wherein on one of the surfaces of the flange area pointing in the axial direction Engagement element is formed. Then, depending on the orientation of the coupling element either the surface of the non-engaging element in the axial direction Flange area on the disc element and holds it in the axial direction Position in which it is freely rotatable about the handle shaft, or the engaging element brought into engagement with the disc element, whereby the disc element rotatably to Handle shaft will.

The coupling element is also preferably the same as a bearing element for the Disc element formed so that the disc element with its attachment opening not sitting directly on the handle shaft, but indirectly on that on the handle shaft attached bearing element. Depending on the material selection for the bearing element - e.g. B. Plastic or the like - the disc element is light relative to the handle shaft rotatable. The disc element sits with a - preferably circular - Top opening on a - preferably cylindrical-shaped - bearing surface.

As mentioned above, it may already be sufficient for automatic operation to decouple the locking elements from the handle shafts and then in an unlocked Determine the position using suitable locking elements, as there are many Door drive devices are designed to be self-locking. To increase the Burglar resistance is, however, an additional or alternative to a self-locking function The drive also locks via the locking elements - also in the automatic Operation - desired. In a particularly preferred embodiment of the Invention achieved by a door drive connection device for coupling the Door drive especially when the window element is activated or decoupled preferably via one of the locking rods to the disc element in such a way that the Gate drive via the window element before opening the gate Unlocking position moves or after the gate closes the locking elements Locked position moves. The coupling of the door drive to the window element can done in a variety of ways. For example, it would be a rope device or the like additional arrangement conceivable on the door leaf from the point of attack of the door operator leads to the disc element. At the point of attack of the door operator, the beginning of a Opening or the end of a closing movement is detected, preferably decoupled disc element is rotated for locking or unlocking. The Rope device or other additional arrangements can be saved if you the door drive - especially near its point of attack - directly at one of the Locking rods couple. This can be done using a suitable gear. is the door leaf is in its locked position, when the door drive is initiated First the gearbox is started, the locking rod is removed from it Locked position brought into the unlocked position. By coupling the Locking bars over the disc element are thereby all the same Locking elements unlocked. This is then carried out in a manner known per se Opening movement of the door leaf. Conversely, closing and Lock the gate. This special arrangement is also purely for one Automatically operated gate, that without the lock and the handles as well as the Handle shaft gets along, advantageous. With such a goal, it would be sufficient to Door leaf, preferably at a central location, to rotatably support the window element. To with this kind of training, everyone would not be on the same level with such training Lock related features alike.

An embodiment of the invention is particularly advantageous Gate locking device, in which the disc element over three each mutually parallel spaced planes extends, the central, for plugging area formed on the handle shaft in the first, particularly close to the lock oriented plane, the arcuate or annular area in a second, thereof inward to the plane spaced away from the door leaf and the attachment area in the still further inwardly spaced third level. Between these three areas are in particular inclined connecting areas or connecting pieces are provided. This On the one hand, training has the advantage that locking bars are also available in different Levels are feasible and can be enclosed on the disc element and thus also could just cross over. On the other hand, it is advantageous that the locking rods particularly vulnerable locking elements are guided further away from the door leaf than those of other bolt elements, which is why the attack on it in the event of a break-in worse is possible.

One, some or all of the locking elements of the gate locking device according to the invention are in a particularly inexpensive yet burglar-proof design as locking rod tips which preferably in their Length adjustable locking rods formed, the associated Counter bearing devices, in particular angularly designed striking plates with Open door openings for receiving the locking rod tips exhibit. The locking rods themselves are for reasons of weight and / or material savings formed from tubes or from tubular sheets, in this The bar made of solid material is preferably tubular or tubular sheet metal insertable adjustable in length. The lateral counter bearing devices are preferably with angular striking plates designed for attachment in the bottom corner area provided, being provided on the wall or floor mounting Elbow an elongated hole for adjustable fastening - retrofitting - is provided.

A combination of the two according to the invention is also particularly advantageous Basic versions. With such a combination, this is preferably at the top horizontal edge of the door leaf arranged first locking element (or one of several such locking elements) retractable for locking and via the engagement lockable between the elongated opening and the engaging element. This retraction movement too can be carried out via the disc element. For this it is preferred that the locking rod of the at least one first locking element over the first Connection or entrainment device is connected to the disc element. at The corresponding connection to the pane element is also a combination of ausund retractable locking elements possible. According to a further development, the Invention provided that on at least one of the upper horizontal edge distinguishing at least one second locking element is provided, whose locking rod via one or the second connection or take-along device is connected to the disc element, the second connection or Driving device in comparison to the first connection or driving device with respect to an imaginary connecting line between the axis of rotation of the Disc element and the respective locking element on the opposite side lies so that when the handle is turned in one direction one of the connected locking rods pulled and the other is pressed at the same time.

According to the invention is a general increase in stroke for the locking members or Bolt elements due to traction sheave fixed on the handle shaft - square achieved that at the same time connecting different numbers and different Locking bolts to be arranged, locking rods, locking members and / or locking elements allowed. A steel shield of several millimeters is preferred in front of the castle provided, a counter plate is to be arranged behind the door leaf, which on the protruding from the steel plate and not accessible from the outside Screw thread bolt with corresponding holes can be placed. The counter plate can also serve as a template with regard to their holes on site, what is particularly advantageous for retrofitting. The threaded bolts and more suitable screws are used to fasten the lock body. The counter plate should so-called "flaring up" - widening, fraying - of the openings in the door leaf area or prevent access through such openings.

The pulley element acting as a traction sheave can be centrically round and many Form connection options for locking bars or similar locking bars. The traction sheave can also be asymmetrical, in particular it can be a special one Connection option for a rod working upwards to the horizontal frame beam have to separately increase the closing or opening stroke of this rod. It So in a first simple version, the length of engagement of the top working locking bolt extended to the increased gap width formation in this area compensate. That the depth of engagement of the bar working upwards is greater than the retreat distance forced by the violent gap formation. The Locking rod is preferably formed from a tube or tubular sheet, in this can be determined by changing the length of a bolt - locking rod tip Solid material inserted. An angle at the side in the bottom corner region is preferred slot-shaped receiving opening provided for the associated bar bolt. The Receiving opening is vertically elongated and thus both at The presence of a threshold in the floor area can also be used in the absence of the same. This is also advantageous for a possible retrofit.

If more preferred on the handle shaft on its outer edge area Thread for a length adjustment nut, which is on the inner wall of the lock housing supports, is provided, the outer handle can be made of destructible plastic, because the handle shaft accessible after destruction - e.g. Square pin - because of the support of the Length adjustment nut on the lock housing and / or because of a support the same on a nut provided for receiving the handle shaft in the lock - Square nut - cannot be pushed out of the lock.

A second solution to the special danger in the upper horizontal area is one separate latch, which is vertically slidably mounted on the upper edge of the door leaf. In the outside of the door leaf in the mirror area of the horizontal frame spar There is a narrowing elongated recess in the latch plate area - e.g. T-shaped recess - such that the extended area faces the lock. In this area, the head of a screw or screw attached to the frame engage the same attachment. In contrast to normal bars, this is used here latches pushed upwards to bring about the opening position, so that the screw head in the extended opening area of the latch flap can intervene. For closing, the bolt is pulled towards the lock so that the shaft of the screw or the like engages in the narrowed area during the Head engages behind the side border of this area. A slump through Widen the gap between the top edge of the door leaf and the horizontal frame spar in this version, the locking tab only more firmly in the locking position. Of course, this version is also with the protective shield - possibly with Counter plate - combinable.

In the following, the structure of the. With reference to FIGS. 7 and 8 Gate locking device in the lock area explained in more detail. The castle area is by a short plate 66 made of 5 mm thick steel, which is shown in detail in FIG. 12, covered. The short plate 66 is on the inside 23 by means of a counter plate acting intermediate plate 68, which is shown in detail in Fig. 11, held. On the Threaded bolts 70, 70 'are attached to the inside of the protective shield. At the bottom, The body is longer than the other threaded bolts 70 ′ which are embodied the lock 24 attached by means of a further nut 54 with ratchet tooth. The The intermediate plate 68 points at the points corresponding to the threaded bolts 70, 70 ' Bores 69 for receiving the same and is by means of nuts 55 without a ratchet tooth attached to the same.

The square pin 72 forming the handle shaft is in the housing of the lock 24 held by a hex nut 74. About this hex nut 74 that on a on the outer edges of the square pin 72 screwed thread is applied Length of the square pin 72 adaptable to the door leaf thickness. At the same time, the Engagement of this so as a length adjusting nut 74 hexagon nut unauthorized pressing out of the square pin 72 from the detection with the Square nut 26 when the outer handle 28 is destroyed and manipulated from the outside. The Outer handle 28 is rotatably connected to the outer portion of the Square pin 72 set.

On the inner portion of the square pin 72 is between the lock 24 and the Inner handle 30 a disc element in the form of a traction sheave 78 is placed against rotation. This traction sheave 78 is an essential element of one Motion transmission device 80, by means of which by turning one of the handles 28, 30 initiated rotary movement as a translational movement on the as locking elements acting locking rod tips 42, 44 is transmitted. To transfer this On the one hand, the traction sheave 78 is non-rotatably on the square pin 72 attached and thus also rotates when the handles 28, 30 are rotated. The Traction sheave 78 is also provided with connecting or driving devices 82, via which the lock-side ends of the locking rods 36, 38 connected to the traction sheave 78 are. The connection or driver devices 82 are in the first Embodiment formed by a screw 84 with self-locking nut 86, the corresponding openings in the lock-side ends of the locking rods 36, 38 and reach through the traction sheave 78.

The traction sheave 78 is explained in more detail below with reference to FIGS. 13 to 15. As can be seen from these figures, the traction sheave 78 has three flat regions 88, 90 and 92, which have the axis of rotation as normal in parallel, but with Distances A and B are spaced apart planes. The first level Area 88 is a central area that the square opening 94 for placing on the Has square pin 72. The second flat region 90 is substantially arcuate and is at a first certain radial distance from through the square opening 94 extending axis of rotation two bores 96 and 97.
