Description

The invention relates to gate locking devices according to the preambles of attached claims 1 and 29, respectively.

Such gate locking devices are from DE 296 17 597 U1 and from known to many single-leaf overhead doors sold by the applicant. These be Known gate locking devices have in the previous normal version tion a hand-operated lock with outer and inner handle and one Square pin as a handle shaft, which engages in a square nut in the lock. The outer handle is formed by a knob and the inner one by T-handle. The distance between the handles is different to adapt to length of door leaf (sheet metal, wood etc.) can be adjusted. For length adjustment and for the respective locking is a screw connection acting on the square pin provided. On both sides of the castle protrude as part of a movement transmission transmission device for transmitting the rotational movement of the handles in a translational movement of the drive bolt, which occurs when the square pin is turned - Closing and opening process - retract and extend. To enable these inputs and extension movement is the square nut within the lock housing with two Provide flanges on the driving pins of the displaceably held drive engage latch. Locking rods are connected to the drive bolts to side locking elements - mostly spring-loaded catch or similar locking links - and pull them open to the lock. The locking elements or locking elements are on the side, mostly in the lower sides end areas of the door leaf attached and thus reach behind the ver closing space facing mirror side of the side frames. So they work Side frames themselves as counter bearing devices for the locking elements.

The known gate locking devices are quite inexpensive adjustable, but offer little resistance to a break-in. For example the door leaf in particular in the area around the castle cylin which will be pierced, allowing you to get inside the lock case and an existing slide on the inside of the lock for opening and  Close the lock by hand. Such a slide is in the be Known locks provided to the lock from the inside of the garage without being able to lock it by hand. Except through an attack in the castle Attempts to break in are often also rich in the latch elements. B. on the snap. To pry open the well-known gates, it is sufficient that Attack points of the frame between this and the door leaf to stem a gap until the catches leave the frame attack. On the other hand, you can Snap also easily through a gap against their feet force are pushed into the open position.

Attempts have already been made to increase security against burglary by increasing the number the locking elements - such as locking links, catches or the like - and in particular especially by locking on the upper horizontal frame area. But it has been shown that just a lock on the upper horizontal Frame area is particularly at risk because there is a gap between the upper door leaf edge and the frame the lightest or furthest possible can be achieved.

From document DE 87 17 999 U1 is a door for shelters, in which Chen documents or the like are to be protected in particular from fire, be known. It should primarily be a door to lock the safe clear out. This known door has a door locking device, with a multiple transmission rods having motion transmission direction for transferring one to be carried out for locking or unlocking Rotational movement of a lockable preferably by locking a lock Handle in a translational movement of at least two on the edge of the door the engagement with respective counterlaid provided on the reveal of the door opening locking devices to be arranged. The well-known Be movement transmission device on the inside of the door section of the Handle shaft in manual operation for joint rotation with it set disc element with at least a first and a second connection or driver device for connecting the ends on the lock side in this way the locking rods with a radial distance from the axis of rotation of the disc element elements on the same, that the locking rods when turning the discs elements with component tangential to this rotation becomes. The known doors naturally have a high level as shelter doors Burglar resistance, but are also designed to be expensive Overhead gates would be neither economical nor sensible.  

US-A-17 468 49 and DE-OS 22 30 232 each relate to door locks Dovetail-like training for just jamming closing of doors without locking them.

Starting from the prior art according to DE 296 17 597 U1 mentioned at the beginning It is an object of the invention to provide a gate locking device in the The preamble of appended claim 1 and appended claim 29, respectively given type with the lowest possible burglary security costs to improve.

This task is accomplished by a gate locking device with the features of the appended claims 1 and 29, respectively.

Advantageous embodiments of the invention are given in the subclaims ben.

According to the invention, therefore, a gate locking device, in particular for a one-leaf overhead door, proposed, with at least two Movement transmission device having locking rods for transferring carry a rotary movement to be carried out for the locking or unlocking nes preferably lockable by locking a lock handle in a translatory movement of at least two on the edge of the door leaf for engagement with respective Ge provided on the frame or the edge of the gate opening gene bearing devices to be arranged locking elements, the movement Transmission device on the inside of the door leaf section of the handle shaft - at least in manual operation - to rotate together with it plug-in or attachable disc element with at least one first and one second connection or take-along device for connecting the lock-side ends of the locking rods 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 also moved.

In the aforementioned training according to the invention, the Locking rods are not, as in the prior art, by means of driving bolts, but by a disc element - a kind of traction sheave - driven. This is on the handle shaft, e.g. B. a square pin, attachable or attachable.  The disc selector then rotates, particularly in manual operation ment together with the handle or handles. So the disc element is like this trained that it can rotate with the handle shaft and in manual Operation can be driven by this, for. B. via direct square engagement. on the other hand can also be used for automatic operation via a door operator an optional decoupling can be provided. With such a disc element ment is a general increase in stroke for the locking rods and thus possible for the locking elements or similar locking elements. At the same time with egg nem such disc element, the connection of different numbers and under locking rods to be arranged differently and accordingly very different locking elements possible. The locking elements no longer only have to be on the side be arranged at the edge of the door leaf, there are also arrangements at the top and bottom conceivable door leaf edge. The disk element can be centrically round and vie le Connection options for locking or locking bars offer. The connection Possibilities are through at least a first and a second connection or Driving device created, such on the disc element are arranged so that the locking rods can be moved tangentially when rotating - i.e. pulled or pressed - are.

A particular advantage of the disk element according to the invention consists in retrofittability. For this purpose, the disk element is preferably not in the lock housed, but outside the same and is from Lock housing seen from further inside in the room to be locked. before is preferably the disc element between the lock housing and the Inside handle arranged. This also has the advantage that the traction sheave with ent speaking large radius can be formed. By the radial distance the connecting or driving devices to the axis of rotation is the respective stroke the locking element connected to it can be selected. In particular, it can a particularly large stroke on the endangered upper horizontal edge orderly locking element can be created.

In the case of the disc element which is plugged onto the handle shaft according to the invention is accordingly particularly advantageous that different strokes can be generated. To be in particular a locking element arranged in the upper door leaf area To make it particularly safe is accordingly further provided according to the invention, that the first and the second connection or driver device differ Chen radial distance from the axis of rotation of the disc element.  

According to an advantageous embodiment, the one for connecting a first locking element to be arranged on the upper horizontal edge of the door leaf first connecting or driving device a greater radial distance than the second or further one, in particular for connecting lateral and / or lower ones Locking element serving connecting or driving device. To be able to do this factory, without the disk element unwieldy in its dimensions or making it wasteful of material is another preferred Embodiment provided that the disc element protrude radially the approach area for attacking the first connection or driver device having.

Another option, particularly vulnerable latch elements in less expensive To make way safer is according to the invention with a gate lock direction, in particular for a single-leaf overhead door, with at least one Locking rod having motion transmission device for transmission against a rotary movement to be carried out for the locking or unlocking by locking a lock lockable handle in a translational Be movement of at least one on the edge of the door leaf for engagement with one on the frame or the edge of the counter bearing device provided for the gate opening ordering locking element given that the locking element, the ins is arranged in particular at the upper horizontal edge of the door leaf, at which Locking rotary movement of the handle to be executed Open unlocking position towards the lock in a retracted locking position is drawn that this locking element an elongated opening and the associated counter bearing device an engaging element for engaging in this 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 in one narrow area and the engaging element has a head for reaching behind of the narrow area and wherein the engaging element and the opening of the are arranged so that the head when moving the door leaf from its opening in the closed position and in the unlocked position element can be inserted in the wide range and by the movement of the bolt elements from the unlocked position to the locked position in the narrow Area reached. In this embodiment of the invention, particularly for above locking elements arranged on the horizontal edge of the door leaf is intended - lateral locking elements can of course also be arranged - the locking element is not extended but retracted for locking. It arrives  thus from the area of the upper gate gap. The locking itself takes place then via engagement between the opening and the engagement element.

A preferred embodiment is characterized by an - in particular resistance of several millimeters - solid metal or the like capable material made of a protective shield - preferably - from the inside Fastened to the outside of the door leaf above the lock area. So that is in addition to the measures provided to secure the locking elements Lich the castle area protected. Both measures together result in a be particularly burglar-proof gate without significantly increasing costs.

To securely attach the protective shield and further strengthen the lock area ken, a counter plate is preferably provided, which can be placed on the Protective shield fixed and protruding from the outside inaccessible towards the inside, with Screw threads, cotter pin slots or cotter pin holes or any other form fastening bolt provided with conclusive attack training formations zen is provided with corresponding mounting holes. This counter plate is So with their holes fixed and not accessible from the outside on the steel plate the door leaf can be placed in between. In addition, the counter plate serve as a template for their drilling on site. This is particularly so when retrofitting an existing or built-in gate with the erfin gate locking device according to the invention very helpful. Through the combination of the protective shield, in particular made of steel, and the counterplate a widening or fraying of openings in the lock area and thus the Zu Accessibility made significantly more difficult by such openings.

The lock itself can be according to a preferred embodiment on the Be fixing bolt of the protective shield with between the lock and the door leaf inserted counter plate.

To beautify the look and / or to confuse burglars or The protective shield can make access to the lock even more difficult a cover may be hidden. In a preferred embodiment, the cover comprises a convertible top shield that is placed over the outer surface of the protective shield becomes. This convertible top sign is preferably attached directly to the protective sign tigt, in particular clipped with the same via a locking device.  

In a further preferred embodiment, the disk element has an arcuate the annular flat region on which one or preferably several ins special the second or the second - connecting or driving devices attack and / or are trained. The disc element has to put on on the handle shaft a central, flat, especially circular, loading rich with an attachment opening with which the disc element on the handle shaft is put on.

According to a version mainly intended for manual operation only The shape of the attachment is for the form-fitting attack with the handle wave trained. Is the handle shaft, for example, by a square pin formed, the attachment opening can be designed as a square opening.

It is particularly advantageous if a ge initially only for manual operation roof can later be retrofitted for automatic operation. For this is provided according to a particularly advantageous embodiment of the invention, that the gate locking device either for manual operation or for the with the help of moving the gate from the open to the closed position and vice versa suitable automatic operation is adjustable. This is preferably done by a coupling device by means of which the Disc element for rotating together with the handle shaft optionally can be coupled for manual operation or if automatic operation is required is decoupled for free rotation. So in the decoupled state turn the disc element freely on the handle shaft, the handles can then without influencing the Rie to be driven by the gate locking device gel elements are rotated. This is possible because door drives are mostly in self-locking manner are formed, so that under certain circumstances even no additional locking is necessary. The disc element is be preferably freely rotatable on the handle shaft, the coupling being direction for coupling the disc element to the handle shaft positive both with the handle shaft and with the disc element in engagement is feasible. To this end, the gate locking device according to the invention is shown in FIG preferred embodiment designed such that the coupling device in particular a form-fit coupling that can be plugged into the handle shaft in a rotationally fixed manner tion element with at least one engagement element - in particular with slave pin - has, which or for coupling the disc element to the Handle shaft can be brought into engagement with the disc element. The clutch element is preferably provided with a through opening. The passage opening  is designed such that the coupling element either around Can be placed on the handle shaft rotated by 180 °. The coupling element has further on a radially projecting flange area, with one of the axially Directionally facing surfaces of the flange area, the engagement element forms is. Depending on the orientation of the coupling element, either then formed without an engaging element in the axial direction facing the Flange area on the disc element and holds it in the axial direction position in which it can be freely rotated around the handle shaft, or the on Handle element is brought into engagement with the disc element, whereby the Disc element becomes rotatable to the handle shaft.

The coupling element is also preferably the same as a bearing element for the Disc element formed so that the disc element with its Aufsetzöff not sitting directly on the handle shaft, but indirectly on that on the Handle shaft mounted bearing element. Depending on the material selection for the La gerelement - z. B. plastic or the like - the disc element is light rotatable relative to the handle shaft. The disc element sits with a - preferably circular - top opening on a - preferably cylinder jacket migen - storage area.

As mentioned above, it can be sufficient for automatic operation be decoupling the locking elements from the handle shafts and then determine in an unlocked position by suitable locking elements, because yes, many door drive devices are designed to be self-locking. To increase Burglary security is, however, in addition or as an alternative to self-locking function of a drive also a locking via the locking elements - too in automatic mode - desired. This is particularly preferred Embodiment of the invention achieved by a door drive connection device for coupling the door operator, especially when activated or decoupled th disc element preferably via one of the locking rods to the disc benelement in such a way that the door drive over the disc element before opening of the gate moves the locking elements in the unlocked position or after closing the gate moves the locking elements in the locked position. The coupling of the Gate drive to the disc element can be done in many ways. It would be for example a rope device or the like additional arrangement bar on the door leaf from the point of application of the door operator to the window element leads. At the point of attack of the door operator, the beginning of an opening or the end of a closing movement is detected, the preferably decoupled disk element  is rotated to lock or unlock. The rope device device or other additional arrangements can be saved if one the door drive - especially near its point of attack - directly on one of the Locking rods couple. This can be done using a suitable gear. If the door leaf is in its locked position, when the Door drive first starts the gearbox, the locking rod is brought from their locked position into the unlocked position. Through the Coupling of the locking rods on the disc element are thereby unlocked all locking elements. Then takes place in a known per se Way the opening movement of the door leaf. The reverse is done accordingly Locking and locking the gate. This special arrangement is otherwise even with a purely automatic door that does not have the lock and the handles and the handle shaft get along, advantageous. With a sol Chen gate it would be sufficient, on the door leaf, preferably at a central point, to mount the disc element rotatably. Except for this special training ren with such training all not related to the castle Features same.

An embodiment of the gate locks according to the invention is particularly advantageous lungsvorrichtung, in which the disc element over three each other extends parallel spaced planes, with the central one being plugged on the handle shaft formed area in the first, particularly close to the lock oriented plane, the arc-shaped or ring-shaped area in a second, therefrom inward to the plane spaced away from the door leaf and the extension richly lies in the even further spaced third level. Between these three areas are in particular inclined connection areas or ver connectors provided. This training has the advantage that Locking rods can also be guided in different levels and on the windows element can be enclosed and could therefore simply cross over. On the other hand, it is advantageous that the locking rods are particularly at risk Bolt elements are guided further away from the door leaf than those of others Bolt elements, which makes it more difficult to attack them in the event of a break-in is.

One, some or all of the locking elements of the gate locks according to the invention lungs device are in a particularly inexpensive and yet burglary safe execution as locking rod tips 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 bars themselves are made of weight and / or material for reasons of economy formed from tubes or from tubular sheets, in This tube or tubular sheet is the bar made of solid material plugged in, adjustable in length. The side counter ger devices are preferably designed for attachment in the floor corner area formed angular striking plates, which on the wall or Bottom bracket provided an elongated hole for adjustable loading consolidation - 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 the above ren horizontal edge of the door leaf arranged first locking element (or egg nes of several such locking elements) for locking and retractable the engagement between the elongated opening and the engaging element can be locked. This retraction movement can also be carried out via the disc element. For this purpose, it is preferred that the locking rod of the at least one first strap gelelements on the first connection or take-along device on the Schei benelement is connected. With appropriate connection to the panes element is also a combination of extending and retracting locking elements possible. For this purpose, according to a development of the invention, it is provided that at least one gate different from the upper horizontal edge sheet edge at least a second locking element is provided, the Ver connecting rod via one or the second connecting or driving device the disc element is connected, the second connection or with take device in comparison to the first connection or take-away device with respect to an imaginary connecting line between the axis of rotation of the shit benelements and the respective locking element on the opposite side lies, so that when turning the handle in one direction one of the connected NEN 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 by torsionally placed on the handle shaft - square Traction sheave reached, which at the same time connecting different numbers and under different locking bars, locking rods, locking members and / or Bolt elements allowed. A steel shield from is preferred in front of the castle several millimeters, with a counter plate behind the door leaf  to be arranged on the steel plate firmly and not from the outside protruding screw bolts with corresponding holes is settable. The counter plate can simultaneously with respect to its holes on site serve as a template, which is particularly advantageous for retrofitting. The screw thread bolts and matching screws are used for fastening the lock body. The counter plate is said to be called "Aufprokeln" - Auf wide, fraying - the openings in the door leaf area or the accessibility prevent through such openings.

The disk element acting as a traction sheave can be centrically round and many connection options for locking bars or the like locking bar gene. The traction sheave can also be asymmetrical, in particular can they a special connection option for an up to the horizontal czar have genholm working rod to separate the closing or opening increase the stroke of this rod. So it will be in a first simple out leadership extends the length of engagement of the locking bar working upwards to compensate for the increased gap width formation in this area. I.e. the engaging depth of the bar working upwards is greater than that due to the force same gap formation forced retreat distance. The locking bar is before trains formed from tube or tubular shaped sheet, in this is ververlen changeable lock a bolt - locking rod tip - made of solid material plugged. An angle with an oblong hole is preferred in the bottom corner area Appropriate opening for the associated bar bolt provided. The on receiving opening is elongated vertically and thus both in front presence of a threshold in the floor area as well as in the absence thereof settable. This is also advantageous for a possible retrofit.

If further preferred on the handle shaft on its outer edge area a thread for a length adjusting nut, which is on the inner wall of the Supports the lock housing, the outer handle can be made of destructible Be plastic, because the handle shaft accessible after destruction - z. B. square pin - because of the support of the length adjustment nut on the lock housing and / or because the same is supported on one for receiving the hand Handle shaft provided in the lock nut - square nut - not inwards from the Lock can be pushed out.

A second solution to the special danger in the upper horizontal area exists in a separate latch flap that can be moved vertically on the upper edge of the door leaf  is stored. In the outside of the door leaf in the mirror area of the horizontal Zargenholmes located latch tab area is a narrowing elongated Recess provided - z. B. T-shaped recess -, such that the erwei area facing the castle. In this area the head can turn on engage the frame fixed screw or similar fastening. Different as with normal bars, the upward-facing bar is used here push the open position upwards so that the screw head can reach into the extended opening area of the latch flap. For the Closing the bolt is pulled towards the lock, so that the shaft of the Screw or the like engages in the narrowed area while the head engages behind the side border of this area. A slump due to gap width tion between the upper edge of the door leaf and the horizontal frame spar pulls in this version, the locking tab only more firmly in the locking position. Selbstver this version with the protective shield - possibly with counter plate - combinable.

The one-leaf overhead door shown in FIGS. 1 to 3, designed as a garage door 10 , has a one-piece door leaf 12 that can be moved overhead from its shown closed position into the open position with a door leaf frame 14 and a door leaf filling 16 and a frame 18 made of sheet metal. The frame 18 consists of two side frame spars, of which only the right side frame spar 20 is shown in FIG. 1, and an upper horizontal frame spar 22nd

The door leaf 12 has a centrally located on the inside of the room to be turned inside 23 arranged conventional lock 24 with here not be necessary driving bolts 25 and a lockable square nut 26 into which the handle shaft designed as a square pin two handles, namely an outer handle 28 and of an inner handle 30 , engages in a rotationally fixed manner. The outside handle 28 is (see FIGS . 3 and 2) formed by a handle knob, while the inner handle 30 is designed as a toggle handle. The frame 18 is anchored via frame anchor 32 to the masonry 34 surrounding the gate opening to be closed.

From the area of the lock 24 , a first locking rod 36 leads upwards and two second locking rods 38 to the side. On the locking rods 36 , 38 is a coupling rod 40 each acting as a bolt or locking element made of solid material - the first locking rod tip acting as the first locking element 42 and the second locking rod tips acting as the second locking element 44 - Kopelt. The locking rod tips 42 , 44 each engage in counter bearing devices 46 fastened to the frame 18 , the masonry 34 or the floor. In the example shown, the lateral counter-bearing devices 46 are formed by shortened running rail wall anchors 48 , which preferably also serve at the same time for anchoring a running rail (not shown), which is guided laterally along the side rails 20 and which also serves as door leaf rollers (also not shown). The upper counter bearing device 46 for the first locking rod tip 42 is formed by a locking bracket 50 which acts as a striking plate and is fastened to the upper frame beam 22 . The track wall anchor 48 is attached to the floor.

The door leaf 12, the locking bars 36, guided on guide angles 52 38 by means of screw - countersunk screw 53 and nut with locking tooth 54 - allow and intermediate pieces 56, the approach angle a displaceable selectable setting the Füh 52, fixed to the door leaf frame fourteenth

In the floor area, a lower stop bracket 58 with a clamping anchor 60 to be anchored in the floor is provided as a stop for the door leaf 12 . The exact structure of the lateral counter-bearing devices 46 is clear from FIGS. 4 to 6.

In the following, the upper counter bearing device 46 will now be explained in more detail with reference to FIGS. 9 and 10.

FIG. 10 shows the detail X from FIG. 1 in an illustration viewed from the inside. The closure angle 50 is also shown in detail in FIG. 9. It can be seen that the locking bracket 50 with its engaging openings 62 , 63 designed as elongated holes for guiding the first locking rod tip 42 both as a guide element 50 a to be fastened to the upper door leaf frame 14 for the first locking rod 36 and as on the frame 18 , ie on the Upper frame member 22 to be fixed counter-bearing element 50 b can be used to hold the first locking rod tip 42 in its locking position. In addition, the closure 50 can also angle c as Zargenbefestigungselement 50 for DOWNVinD the vertical Zargenholmes be used 22nd The formation of elongated holes as engaging openings 62 and 63 is particularly useful when upgrading existing gates with the first locking rod 36 , since the locking rod guide is thus better adaptable to the circumstances. At the gate leaf filling 16 , the nend shutter angle 50 a is fastened by means of self-tapping screws 64 as a guide element for the first locking rod 42 .

In the following, the structure of the Torverriege treatment device in the castle area will now be explained in more detail with reference to FIGS . 7 and 8. The lock area is covered by a short shield 66 made of 5 mm thick steel, which is shown in detail in FIG. 12. The protective shield 66 is held on the inside 23 by means of an intermediate plate acting as a counter plate 68 , which is shown in detail in FIG. 11. On the inside of the protective shield 66 , fastening bolts 70 , 70 'are formed as bolts. The body of the lock 24 is fastened to the lower fastening bolt 70 ′, which is longer than the other fastening bolts 70 , by means of a further nut 54 with a locking tooth. The counter plate 68 has the mounting bolts 70 , 70 'ent speaking locations on holes 69 for receiving the same and is fastened to the same by means of nuts 55 without a ratchet tooth.

The square pin forming the handle shaft 72 is held in the housing of the lock 24 by means of a hexagon nut 74 . This hexagonal nut 74 which is screwed onto a on the outer edges of the square pin 72 with a threading, the length of the main handle shaft 72 to the door leaf is adjustable. At the same time, the engagement of this hexagon nut 74, which thus serves as a length adjustment nut, prevents the handle shaft 72 from being unauthorizedly pressed out of the detection with the square nut 26 in the event of the outer handle 28 being destroyed and manipulation from the outside. The outer handle 28 is rotatably placed on the outer portion of the handle shaft 72 via a square 76 .

A disc element 78 in the form of a traction sheave is placed on the inner portion of the handle shaft 72 between the lock 24 and the inner handle 30 in a rotationally fixed manner. This disc element 78 is an essential element of a movement transmission device 80 , by means of which a rotary movement initiated by turning one of the handles 28 , 30 is transmitted as a translational movement to the locking rod tips 42 , 44 acting as locking elements. To transmit this movement, the disk element 78 is placed on the one hand in a torsion-proof manner on the handle shaft 72 and thus also rotates when the handles 28 , 30 are rotated. The disk element 78 is also provided with connecting or driving devices 82 , 83 , via which the lock-side ends of the locking rods 36 , 38 are connected to the disk element 78 . The connection or driving devices 82 , 83 are formed in the first embodiment by a screw 84 with a self-locking nut 86 , the corre sponding openings in the lock ends of the locking rods 36 , 38 and the traction sheave 78 .

The disk element 78 is explained in more detail below with reference to FIGS. 13 to 15. As can be seen from these figures, the disk element 78 has three planar areas 88 , 90 and 92 , which run in each case in parallel with the axis of rotation as normal, but spaced apart by distances A and B from E planes. The first flat area is a central flat area 88 , which has the attachment opening 94 designed as a square opening for placement on the handle shaft 72 . The second flat area is a substantially arcuate or ring-shaped flat area 90 which , at a first specific radial distance from the axis of rotation running through the attachment opening 94 , has two openings 96 and 97 designed as bores. Through these openings 96 and 97 , the disk element 78 is penetrated by the above-mentioned screw 84 to form a second connecting or driving device 82 for the lateral, second locking rods 38 . At a greater distance C from the axis of rotation running through the attachment opening 94 there is a further opening 98 designed as a bore. This opening 98 is located in the third flat area designed as the protruding attachment area 92 , which is attached to the curved or annular flat area 90 at one point and strives radially outward. Through the opening 98 an engagement point for the first connection or driving device 83 for the first locking rod 36 is defined.

Between the flat areas 88 , 90 , 92 there are continuous inclined connection areas 100 , so that the traction sheave 78 overall plate-shaped with a circular arc edge (second, arc-shaped or annular flat loading area 90 ) and the radially projecting flat attachment area 92 ) is trained.

By this design of the disc member 78 can be for the first United connecting rod 36 and thus for the first locking element acting as the first locking rod tip 42 a larger stroke than for the second locking rods 38 and the attached, acting as a second, lateral Riegelele elements acting second Lock rod tips 44 . Thus, the garage gate 10 burglary attempts a great resistance.
