LOCKING DEVICE FOR A GATE AND THE THEREOF MISSED GATE

The invention relates to a locking device for a gate, in particular a garage or industrial gate and more particularly a single-leaf overhead gate, which is arranged or is to be arranged on the gate leaf at a distance from the edge of the gate leaf for actuating and/or locking at least two locking rods or similar motion transmission devices or at least two groups of locking rods or similar motion transmission devices, each of which is connected at the other end to locking or latch devices arranged on the edge of the gate leaf for opening and closing and/or locking the gate.

In such a locking device, which is now common in many garage doors, a lock is located at an ergonomically accessible location away from the edge of the door leaf, for example in the middle or on the side in the lower third of the door leaf. The usual locking devices also have an outside handle and an inside handle, which are used to operate the lock to open and close the door.

A locking device is also provided, which usually has a locking cylinder that can be operated from the outside using a key and a pin that can be operated by hand from the inside, as well as a locking mechanism inside the lock that can be operated via the locking cylinder or the pin. The lock can be locked using the locking device, i.e. a handle operation for opening and closing the gate is blocked. In order to transfer the movements required to release the opening movement and close the gate from the lock to a bolt or catch arranged on the edge of the gate leaf and not accessible from the outside, locking rods are provided, which are connected at one end to parts of the lock that can be moved using the handles and locked by the locking device, and at the other end are either designed as a bolt or catch themselves or are connected to one.

The known locking devices and the doors equipped with them do have the advantage that they can be operated quickly and easily by authorized persons. The disadvantage, however, is that they offer little resistance to break-ins. For example, many conventional industrial and garage doors can be broken open with a crowbar with some skill by pushing the lock into its open position by attacking the locking bar or a locking bar.

The object of the invention is to create a locking device of the type mentioned above which is easy to operate, but nevertheless offers greater security against break-ins

11 I...

&igr;* ·

Furthermore, a gate equipped with such a locking device that is easy to operate but secure should be created.

To achieve this object, a locking device of the type mentioned at the outset is characterized in that it has a first lock for actuating and/or locking a first locking rod or locking rod group or similar first movement transmission device and at least one second lock for actuating and/or locking the second or further locking rod or locking rod group or similar second movement transmission device.

This means that a second additional locking device is not simply provided, which would complicate operation and installation compared to gates with only one locking device. Rather, the one locking device has two or more locks, each of which operates or locks different locking rods. In order to break in, both or all of the locks would then have to be overcome, i.e. they would have to be levered open one after the other.

Advantageous embodiments of the invention are the subject of the subclaims.

Preferably, both or all locks are each provided with a locking device, preferably having a locking cylinder or the like, by means of which they can be operated and/or locked separately from one another from the outside by means of a key, code entry or the like.

can be locked. The authorised person can therefore decide whether to secure the gate once or twice. For example, daytime operation is possible in which only one of the locks can be conveniently unlocked and/or operated from the outside, e.g. by turning a key for a quarter of a turn, entering a short code or similar identification, while the other remains completely free or can be operated manually. Both locks can then be locked at night. If the locking device of the second or each additional lock includes a locking cylinder with a round profile at the key insertion end, the second lock or the additional locks can be retrofitted more easily. Round holes can simply be drilled and are therefore easier for gate owners to create later than an opening required for a profile cylinder.

It is also preferred that both or all locks are provided with an internal operating device, in particular comprising an internal handle, e.g. a rotary handle or the like, for operating and/or locking or unlocking from the inside. The locks can therefore also be operated separately from the inside, even though they belong to the same locking device and are therefore assigned to one another. This can happen, for example, by simultaneously grabbing the handles or the like with both hands. This hardly affects the convenience of operation from the inside; nevertheless, separate systems are created that are more difficult for unauthorized persons to overcome.

The way in which the locking device, i.e. the locks it comprises, can be operated from the outside can be different. In a preferred embodiment of the invention, only the first lock has an external handle or similar external operating device for operating the lock from the outside. The first lock can therefore be easily operated by hand to open and close the gate, and it can also be locked and unlocked using a key if necessary. In one version of this embodiment of the invention, the second lock can only be operated from the outside using a key, i.e. the gate is automatically locked again after it has slammed shut. Opening is then carried out by briefly turning the key in the second lock and manually operating the first lock. The second lock can be limited to this simple function, but like the first lock it can also have an additional locking function, e.g. by turning the key further. Another advantageous version of the design with only one external handle includes a coupling of the operation of the locks so that they can be operated together via the single external handle to open and close the door leaf. The two locks are preferably locked separately.

As an alternative to the design with only a single external operating device, it can also be provided that both or several or all of the locks are each provided with an external handle or similar external operating device for operation from the outside. The respective lock can then be operated via the individual external handles. The external handles are preferably

arranged in such a way that they can be grasped with the hands at the same time. Here too, however, there is the possibility of coupling, so that only one of the external handles needs to be moved to operate several locks together. Instead of "external handles" or "internal handles", in principle any manual operating device suitable for operating locks can be used, ie rotary handles, pull handles, push buttons, latches, folding handles or the like can be used. Rotary handles are preferably provided which also offer a pulling option for raising the door leaf.

As already indicated, a design of the lock device according to the invention is particularly preferred which has a coupling device for coupling the actuation of the two or several or all locks. This means that when only one of the locks is actuated, the other can also be actuated at the same time, so that, as with a gate with only one lock, one-hand operation can in principle be achieved. The coupling device preferably comprises a coupling of the inner actuation devices of the locks, i.e., for example, the inner handles are connected to one another via a rod or other gear for joint rotation. The coupling could comprise the inner and outer actuation, but it can also be limited to the inner actuation, for example. The latter is possible if the inner and outer actuation devices of each lock are decoupled from one another. With such a decoupling, for example, the inner and outer rotary handles of each lock can be rotated independently of one another. To easily implement the coupling

·

·

It is preferred that it has on each of the locks to be coupled together a lever device which pivots when the lock is actuated and which preferably comprises a Z-shaped tab engaging the handle shaft, and that the lever devices of the locks to be coupled are connected to one another for joint pivoting via at least one connecting rod.

In order to facilitate convenient joint operation of the locks and yet still offer a high level of security, it is further preferred that the locks are arranged in close proximity to one another and preferably lie one above the other, with a first lock, preferably arranged at the top, having one or more upper locking rods for actuating and/or locking latch or catch devices arranged in the upper region or upper side region of the gate leaf, and a second lock, preferably arranged at the bottom, having one or more lower locking rods for actuating and/or locking latch or catch devices arranged in the lower region or lower side region of the gate leaf.

A particularly easy-to-retrofit design of the lock device according to the invention, which nevertheless offers good support, comprises an additional U-shaped strut as a base for the second or further lock, which can be clamped to the first lock and screwed to the door leaf frame. This strut creates a reinforcement of the door leaf area, which is located in the middle or offset to the side of the middle, depending on the arrangement of the lock device, and to which the second lock is to be attached. At the same time

Because it is clamped to the first lock, which is permanently attached to the gate leaf, it only needs to be screwed to the edge of the gate leaf, so that it is easy to install.

A gate provided with a locking device according to the invention, in particular a garage or industrial gate and more particularly a single-leaf overhead gate, is characterized by a high level of burglary protection combined with ease of operation.

Fig. 1 shows an external view of a door leaf 10 of a single-leaf tilting or swinging door for a garage that can be moved overhead. The door leaf 10 is provided with a first embodiment of a locking device 12. By operating the locking device 12, the door leaf 10 can be released from its closed position for opening. For operation from the outside, the locking device 12 is provided with an external actuating device in the form of a round handle 14. The round handle 14 can be rotated about an axis that runs essentially perpendicular to the plane of the door leaf. A handle recess 16 on the round handle 14 also offers a grip by means of which the door leaf 10 can be more easily pulled out of its closed position for opening after the locking device 12 has been operated. The key inserts of two locking cylinders 18 and 20 can also be seen. The locking cylinders 18, 20 are each part of two locking devices, by means of which the locking device 12 can be locked twice, so that the operation of the same is blocked via the round handle 14. The key insertion end of the

&iacgr;&ogr;

The end of the first locking cylinder 18 has a "keyhole" profile that is usual for gate leaf key cylinders, while the key insertion end of the second key cylinder 20 has a round cross-section. The locking cylinders 18, 20 are each seated in matching openings in the gate leaf, i.e. a "keyhole" profile opening or a round hole.

Fig. 2 and Fig. 6 show an interior view of the first embodiment of the locking device 12. The locking device 12 has a first lock 22 and a second lock 24 arranged directly below the first lock 22. The two locks 22, 24 are constructed identically (apart from their design explained above, which is visible from the outside).

The first lock 22 has a first locking device which comprises the first locking cylinder 18 and can be locked or unlocked from the outside via the first locking cylinder 18 by means of this. The second lock 24 has a second locking device which comprises the second locking cylinder 20 and can be locked and unlocked from the outside via the second locking cylinder 20 independently of the first lock 22. Both locks 22, 24 are also provided with a locking pin 26 or 28 which can be accessed from the inside for locking and unlocking from the inside without using a key. For operation from the inside, the locks 22, 26 also have an internal actuating device in the form of an internal handle 30 or 32. Lock tabs 33 protrude from the sides of the housings of the locks 22, 24 and which can be turned against a pre-tension in an

can be retracted in a known manner. The first lock 22 is connected to a first group of locking rods, namely three first locking rods 34, 36, 38, at its two lock tabs 33 and at a Z-shaped tab 35 which engages the handle shaft of the inner handle 30. The first locking rods 34, 36, 38 are actuated by operating the first lock 22 and moved accordingly via the retraction movement of the lock tabs 33. They transfer this movement to bolts or catches or similar first locking or latch devices (not shown) arranged at the other end of the first locking rods 34, 36, 38. The first locking or latch devices are arranged in the upper region or upper side region of the door leaf 10 on the edge of the door leaf and engage in corresponding openings in the frame (also not shown) to hold the door leaf 10 in its closed position. In addition, the round handle 14 shown in Fig. 1 sits together with the first inner handle 30 provided on the first lock 22 on a common shaft, so that the handles 14, 30 move together.

The second lock 24 is also connected via a group of locking rods 40, 42 to latch or locking devices arranged on the edge of the door leaf in the form of bolts or catches or the like for the purpose of actuating the same. The second latch or locking devices (also not shown) to be actuated by the second lock via the second locking rods 40, 42 are, however, located in the lower area or lower side area of the door leaf 12. The second lock 24 is mounted on a short U-shaped central strut 43 which is located under

the first lock 22 and is screwed to the lower edge of the gate leaf in a manner not shown in detail.

Actuating devices of the locks 22, 24, i.e. in the example shown here the inner handles 30 and 32 or their shafts, are coupled by means of a coupling device 44 for joint movement. The coupling device has a rod with a first Z-shaped tab 46, a second Z-shaped tab 48 and a connecting rod 50 between the tabs 46, 48. The tabs 46, 48 act as lever devices that pivot with a rotation of the handle shafts. For this purpose, like the tab 35 (see Fig. 7, which shows one of the tabs 46, 48, 35 in a detailed view), they have a square opening 54 at one end 52, with which they are placed on a square pin (not explicitly shown) serving as a handle shaft. At the other end 56, the tabs 46, 48, 35 have a fastening section 58. In the case of the tabs 46, 48, the two ends of the connecting rod 50 and, in the case of the tab 35, the lock-side end of the locking rod 36 are each rotatably fastened to this.

The locking device 12 according to the first embodiment is operated in the following way: It can be operated from the outside by turning the round handle 14. The rotation of the round handle 14, with which the first inner handle 30 turns, causes a movement of the first group of locking rods 34, 36, 38, which transmit the movement to the first locking and/or latch devices arranged in the upper area of the door leaf. The latter release

This releases it from its grip on the frame and the upper section of the door leaf 10 is released. The rotation of the first inside handle 30 is also transmitted to the second inside handle 32 via the coupling device 44 and the second lock 24 is operated. This operates the second group of locking rods 40, 42 so that the door leaf 10 is also released at its second latch and/or locking devices arranged in the lower section. The door leaf 10 can then be pulled out of its closed position at the recessed handle 16 and brought into its open position upside down. The door leaf 10 is closed in a similar way, only in reverse, although if the locking or latch devices have catches, it is not absolutely necessary to operate the locks. The locking device 12 can be operated from the inside using either of the two inside handles 30, 32.

The two locks 22 and 24 can be locked separately from one another by means of their locking devices, which can be operated from the outside via the locking cylinders 18 and 20 or from the inside via the locking pins 26, 28, so that it is not possible to open the door leaf 10. The locking mechanisms which can be actuated by the locking cylinders 18, 20 have the following functions: With a complete key turn (alternatively moving the locking pin 26 or 28 into the unlocking position), the lock 22 or 24 can be operated continuously without a key. If both locking mechanisms are brought into this release state, the door can also be opened and closed from the outside without a key. The locking mechanisms

but in addition to the locking function, they also have an operating function: the respective lock can be operated with a quarter turn of the key, but is locked again after the gate is closed again. This makes it possible, for example, to operate the gate with only the locking mechanism of the first lock 22 in the release position. To open the gate from the outside, the second lock 24 can then be operated by turning the key a quarter turn. After slamming shut, the gate leaf 10 is then locked again with the second lock 24, i.e. opening from the outside is not possible without a key. Both locks 22, 24 can then be locked at night.

Variations of the first embodiment not shown include omitting one of the inner handles 30, 32 or modifications to the coupling device 44, which can also include toothed or chain gears or the like instead of the lever-connecting rod gear. In addition, the round handle 14 could be decoupled from the first inner handle 40, so that external operation can only be carried out decoupled via the round handle 14 (operation of the first lock 22) and key (operation of the second lock 24), but the internal operation can be carried out coupled via an inner handle 30 or 32.

Instead of the purely mechanical locking mechanisms to be operated by means of the locking cylinders 18, 20, other locking devices such as those with code entry devices or other electrical or electronic devices for checking user authorization can also be used.

In further modifications, the dual function (locking and actuation) is not implemented in one or both of the locking devices. In this case, one or both of the locking cylinders 18 and 20 only serve to lock, i.e. it is not possible to operate the respective lock 22, 24 using a key. To open the door leaf, one of the coupled actuation devices, i.e. one of the handles 14, 30, 32, must always be operated.

A further modification of the first embodiment, not shown, contains more than two locks. These can be fully or only partially coupled to one another.

A second embodiment of a locking device 62 for a single-leaf overhead garage door is explained below with reference to Figs. 3 and 4. Fig. 3 shows the external view, Fig. 4 the corresponding internal view of the area of the door leaf 10 provided with the locking device 62. In contrast to the locking device 12, the locking device 62 has no coupling device, but instead a second round handle 64.

Otherwise, the structure is essentially the same as in the first embodiment. The same parts are designated with the same reference numbers and for a description thereof, reference is made to the above explanations. The second round handle 64 has a common handle shaft with the second inner handle 32, via which the second lock 24 can be actuated.

In the second embodiment 62, the gate can be locked by two separate systems that are spatially close to each other and operate different locking bar groups. Each lock 22, 24 has its own outside handle 14 or 64 and its own locking cylinder 18 or 22.

A third embodiment of the locking device 66 has the shape shown in Fig. 1 from the outside and the shape shown in Fig. 4 from the inside. In the third embodiment 66, the second lock 24 therefore has no external handle and is also not coupled to the first lock 22. It can therefore only be operated from the outside by turning the key (1/4 turn). From the inside, it can be operated via the second internal handle 32. The second lock 24 of the locking device 66 is locked or unlocked from the outside by a complete turn of the key, and from the inside by moving the second locking pin 28. In a modification of the locking device 66 of the third embodiment, the second locking rods 40, 42 to be actuated by the second lock 24 can be brought completely into a retracted position by a turn of the key (e.g. opposite to the locking direction of rotation), so that the door can subsequently only be opened and closed by actuating the first lock 22 via the handles 14, 30.

Fig. 5 shows an interior view of a locking device 68 in a fourth embodiment. It corresponds essentially to the second embodiment 62 (two external handles 14, 64) or alternatively to the third embodiment (one external handle 14, but dual function of the locking

locking mechanism of the lock 24 not provided with an external handle, i.e. operation and locking via key), whereby the first group of locking rods 34, 36, 38 also has two further locking rods 70 and 72. The other first locking rods 70 and 72 are also operated via the first lock 22. The locking rods 70 and 72 do not, however, lead to locking or latch devices arranged at the top of the door leaf 10. Rather, the locking device 68 provides additional latch or latch devices just above the latch and latch devices to be operated by the second lock 24. These additional latch or latch devices, which are also not shown, can also be operated by means of the first lock 22. The first lock 22 thus operates five latch or latch devices distributed around the edge of the door leaf.

Further embodiments or modifications can be obtained by any combination of the individual features of the first to fourth embodiments or their modifications with one another. In the second to fourth embodiments, all of the modifications explained in the first embodiment that do not directly relate to the coupling device are thus conceivable in principle.

Of course, the coupling device can also be provided in the locking device 62 with two external handles 14, 64. Instead of locking rods, other movement transmission devices could in principle also be provided between the locks 22, 24 and the latch or bolt devices.

Important aspects of the locking device described here are summarized below using the illustration in Fig. 2:

In order to increase the burglary security of a garage or industrial door, in particular a single-leaf overhead door, without restricting the ease of use too much, a locking device (12) with at least two locks (22, 24) is proposed, which are preferably arranged spatially close to one another at an ergonomically favorable location on the door leaf 10, but each actuate separate groups of locking rods (34, 36, 38; 40, 42) or similar connections to locking or latch devices. The locks (22, 24) can be locked and unlocked separately from one another via their own locking devices, which comprise, for example, locking cylinders (18, 20). In a preferred embodiment, a coupling device (44) is provided for coupling individual actuating devices (30, 32) of the at least two locks (22, 24) so that they can be actuated together in the unlocked state.
