In the following, the invention will be explained in more detail by means of graphical representations. In this regard, FIG. 1 shows an embodiment according to the invention of the locking device 1 mounted on a single-acting revolving door. Figure 2 shows the construction of the locking device 1 in an enlarged representation.

In the exemplary embodiment in FIG. 1, the single-action sliding door comprises a frame 5 and a leaf 6, which is housed in bolts 2 so that it can rotate about the vertical axis of the door. The locking device 1 mounted on the frame comprises a pin module 3 and a pin receiving device 4. In the case shown, the pin module 3 is laterally mounted on the frame 5. The mounting is preferably carried out inside the frame 5. The pin receiving device 4 is mounted on the side of the leaf of the pin module 3 in an opposite way, also preferably from the inside.

The pin module 3 has a housing 31 with a pin element 32 housed in a displaceable manner therein in a vertical direction, which is biased by a first spring 33 into the unlocking position. In the unlocked position the pin element 32 is inserted into the housing 31 and does not protrude with its free end from the housing 31 (Figures 2 and 2a). In the case shown, the first spring 33 is designed as an arm spring, which is rotatably mounted on a fixed bearing point 33d on the housing and is supported by its first arm 33a on a housing stop and with its second arm 33b in a drive element 32m of the pin element 32.

An electrically switchable release-hold device 34 is arranged in the housing 31 as an additional component. This has an electromagnet 34m which acts in conjunction with a pin 32s arranged in the pin element 32. The electromagnet 34m comprises a coil 34s which acts in conjunction with an armature 34a pivotally housed in the housing 31. Armature 34a is housed in a pivoting as a single-arm lever with respect to an axis of rotation 34d in such a way that it can adopt a release position (figure 2) adjacent to the electromagnet 34m and a closed position (figure 2a) which, in the case shown, is pivoted clockwise. Between the electromagnet 34m and the armature 34a is arranged a helical compression spring that urges the armature 34a into its closed position (figure 2a). The armature 34a has a projecting stop with which, in the closed position of the armature 34a, it engages the pin 32s from behind and thus keeps the pin element 32 in its unlocked position. In the release position of armature 34a, armature 34a has pivoted counterclockwise and thus disengaged from pin 32s.

As an additional component in the housing 31, a locking-retention device 35 is arranged. It comprises a first single-arm lever 35h. This first lever 35h is pivotally housed in a bearing 32d in the pin element 32 and has in the center a retaining bolt 35n and at its free end a pulley 35r (Figures 2 and 2a). A second spring 35f is arranged on the pin element, which is housed in the bearing 32d, and which with its first bearing arm rests on the pin element 32 and with its second bearing arm rests on the retaining bolt. 35n of the first lever 35h. The first lever 35h is urged by removing the pin element 32 through the second spring 35f in such a way that the pulley 35r of the first lever 35h runs along a linear guide on the inner side of the housing 31, opposite the front plate (Figures 2b and 2c), in the representation in Figure 2 the first lever 35h rotates clockwise. Additionally, the locking device 35 comprises a second single-arm lever 35i, which is rotatably housed in the housing 31 at the fulcrum 33d. The second lever 35i has a notch 35k in the center and a retaining plate 35p at its free end. In the case shown, the second lever 35i, to secure the first lever 35h, pivots counterclockwise (figure 2b) and is held by the second electromagnet 35m of the locking device 35 when acting on the retention plate 35p in this pivoted position. (figure 2c). In this position, engagement of the retaining bolt 35n of the first lever 35h occurs in the notch 35k of the second lever 35i. The lock-hold device 35 can be configured such that it can be operated with quiescent current or working current. For quiescent current operation, voltage is supplied to the second electromagnet 35m, to pivot the second lever 35i to secure the first lever 35h. In operating current operation, the second electromagnet 35m, by feeding its coil, moves the second lever 35i to stop securing the first lever 35h, the second lever 35i being configured in operating current operation in such a way which by means of a spring bias secures the first lever 35h permanently. In operating current operation, for an emergency release, for example, a profile cylinder can be arranged below the second electromagnet 35m in the casing 31, which through a slide or a linkage acts on the second lever 35i to release the first lever 35h.

The pin receiving device 4 housed in the blade has a pin housing 41 arranged on the front plate, in which the pin element is hooked in the locking position (Figures 2b and 2c). A magnetic device 42 is arranged in the pin housing (Figures 2 to 2c). The latter has, in the case shown, a permanent magnet which is configured in such a way that in the closing position of the door it brings the pin element 32 to the locking position, once the unlocking-retaining device 34 of the element of pin 32 has been activated and thus the pin element 32 can be released (FIG. 2b). To secure the pin member 32 in the locked position, the lock-retainer 35 holds the pin member 32 in the locked position (FIG. 2c). For this, the locking-holding device 35 is electrically switched accordingly.

For the unlocking operation the lock-retention device 35 must first be electrically activated. The unlocking stroke of the pin element 32 is achieved in the exemplary embodiment shown because the pin element 32 is disengaged with the manual opening of the leaf 6 through an outlet chamfer configured at the free end of the pin element 32 (Figures 4 to 4d). The exemplary embodiment shown involves use in a single-action revolving door.

The first spring 33 urges the pin element 32 in the unlocking direction. Once the pin element 32, due to the opening position of the leaf 6, is disengaged from the magnetic device 42, the action of the first spring 33 causes the complete entry movement of the pin element 32 to its position of unlocking. In the unlocking position, with the pin element 32 fully engaged, the pin element 32 with the pin 32s engages with the armature 34a of the unlocking-retaining device 34. The unlocking-retaining device 34, in the locked position. closure of the armature 34a, holds the pin element 32s (figure 2a).

In a modified embodiment, the locking device 1 can also be used on a swing door. In this case, the pin element 32, in addition to the exit chamfer, must also have an entrance chamfer (FIG. 4). The pin element 32 then has a symmetrical configuration at its end, so that the door leaf 6 as an oscillating door leaf can be rotated from the locking position both to the left and to the right. The latch element 32, with the unlocking-retention device 34 activated, acts as a spring latch, which centers the door leaf 6 in the closed position, because the latch element 32 is extracted in the closed position through through the magnetic device 42. In particular embodiments of the swing door application, in addition to the pin element 3, a spring-loaded latch may be provided, so that the swing door can be operated without the release device having been released. release-retention 34 acting on the pin element. The centering of the swing door in the zero position then takes place exclusively via the spring loaded latch with the pin element clamped in the unlocked position.

In modified embodiments the pin module 3 can also be mounted on the horizontal spar of the frame 5 and the pin receiving device 4 can be mounted in the corresponding position on the sash side.

Furthermore, the locking device 1 can be installed with a reverse mounting, specifically the pin module 3 on the side of the sash and the pin receiving device 4 on the side of the frame.

Furthermore, modified embodiments are possible in which the magnetic device 41 is configured as an electromagnetic device. In these embodiments, the pin element 32 can also be configured without an exit chamfer or without an entrance chamfer.

Further application possibilities of modified embodiments are in sliding doors, as shown in figure 3. In this case the pin element 32 will be realized with an exit chamfer or entrance chamfer arranged on the front side. Figures 4b, 4c, 4d show these embodiments. Also in this case the pin module 3 can be arranged on the frame side on the upper side member preferably in the sliding guide of the sliding sash and the pin receiving device 4 on the sash side. In this case too, reverse mounting is possible. The direction of movement of the sliding door is represented in Figure 3 by an arrow.

Figure 4d shows an exemplary embodiment of a pin element 32, which can be used universally for both swing gates and sliding gates, because it has an exit chamfer and / or an entry chamfer for a sliding door and a chamfer exit and / or entry chamfer for a revolving door.

The pin elements 32 shown with entry chamfers and exit chamfers can also be used with conventional locking devices and conventional electric door openers. This applies in particular also for universal pin elements of FIG. 4d, which can be used both for sliding doors as well as for revolving doors. Furthermore, this also applies to modified pin elements, which only have entry chamfers or exit chamfers, in particular in each case for revolving doors or for sliding doors. These conventional locking devices can have a lock box that can be mounted on or in the frame or on or in the leaf, in which a preferably conventional locking mechanism is housed. In this type of embodiment, the lock box can be configured as a lock box of a mortise lock for internal mounting. In all these different embodiments, the locking mechanism can control a pin and / or a latch, the pin and / or latch being removable in the closed position of the door to the pin housing and / or having been removed thereto. and the bolt and / or latch in the lock box having been pushed into the door open position. Preferred embodiments provide that at least the pin is inserted in the lock box. The pin and / or latch may co-operate with the magnetic device 42 arranged in the pin housing 41.

In the case of embodiments as a conventional locking device with a locking mechanism in a lock box, the locking mechanism can be provided with an electrically switchable locking-retaining device 35 and with an electrically switchable unlocking-retaining device 34, preferably arranged in the lock box. In modified embodiments the electrically switchable locking-retaining device 35 and / or the electrically switchable unlocking-retaining device 34 may also be arranged outside the lock case at or adjacent to the locking device. pin housing 4.

In the various embodiments, it is particularly advantageous if the pin element 32 is designed with an exit chamfer and / or an entrance chamfer and that in the case of the exit chamfer, the door can be pushed and / or pushed open. door traction acting in conjunction with the pin housing, without it being necessary to actively drive the pin member through a separate actuator.

The embodiments according to the invention can be configured for single-action doors, swing doors or sliding doors. In this sense, in preferred embodiments, the leaf can be made of glass, so that they are so-called glass doors. In the embodiments according to the invention, the release-retention device 34 as well as the entry chamfer and exit chamfer of the pin element 32 described in the previous description of the figures in connection with the exemplary embodiments are optional. In the embodiments according to the invention, it is essential that an electrical locking-retaining device and a magnetic device are provided, the magnetic device being configured in such a way that in order to reach the locking position of the pin element 32 the device for receiving the pin 4 and pin module 3 are associated with each other such that pin element 32 by the magnetic force of magnetic device 42 can move to the locked position and can engage with the pin housing to produce a lock. In order to reach the unlock position of the pin element 32, with the electrical locking-retention device turned off, the pin element 32 can be disengaged from the magnetic device 42, because the pin element 32 and / or the magnetic device 42 can be actuated. This actuation of the magnetic device, as the magnetic device has an electromagnet, can occur by electrical switching of the electromagnet. However, it can also be produced by displacing the magnetic device by means of a corresponding manual or electrical actuating device, configured as an actuating device that brings the magnetic device to the unlocked position. In a corresponding manner, in addition, a manual or electrical actuating device can also be configured for the pin element.
