Description

The invention relates to a device for automatic locking of the passive leaf of a two-leaf door, in particular a glass door.

Two-leaf doors in general, as well as double-leaf glass doors in particular from the prior art are known per se, which is why it does not require a separate documentary proof at this point.

In a conventional manner, a two-leaf door has a so-called passive wing on the one hand and a walking leaf on the other. In this case, the active leaf is locked relative to the fixed leaf and the inactive leaf relative to the frame enclosing the two wings of the door in the rule. For locking the inactive leaf relative to the frame, automatically acting systems are known which lead to an automatic locking of the inactive leaf when the active leaf is locked relative to the inactive leaf.

They are from the state of the art, eg document GB 19745 A , Automatic pawl locks have become known, wherein the latch of the lock is housed in the passive leaf itself and can be moved out of this or into this. If the active leaf is opened, the inactive leaf must also be opened at the same time. A follower ensures that the inactive leaf closes and then the active leaf closes first. Preferably, anti-panic locks are used, in particular for smoke protection doors. It can then be opened with a handle of the active leaf, which at the same time the inactive leaf is unlocked and can be opened.

The above-mentioned and known from the prior art in-wing locks have proven themselves in everyday practical use, but are not suitable for double-leaf glass doors, since the latch of the lock in a passive leaf provided recess is guided longitudinally displaceable, which is not possible with all-glass doors.

For automatic locking of double-leaf all-glass doors, closing rockers can usually be used. A closing rocker makes use - as the name implies - the Wippfunktion advantage, wherein a passing of the one part of the rocker through the active leaf leads to a lifting of the other part of the closing rocker, which then has a locking of the passive leaf result. In this case, the closing rocker is spring-loaded, so that when a reopening of the active leaf the closing rocker is moved back to its original position, in which the inactive leaf is unlocked.

Although the above-described closing rockers are frequently used, their use and application is not without problems. A particular disadvantage of previously known closing rockers is that they have to be very accurately formed in their geometrical dimensions and, in particular, must be positioned and mounted very precisely in position in relation to the moving leaf on the one hand and the stationary leaf on the other hand. As a result, in particular, the assembly work proves to be complicated and thus costly in previously known closing rockers. If an assembly is inaccurate, for example with regard to the locking points provided by a rocker, proper functioning and thus proper closing by means of the rocker can no longer be guaranteed. In this context, the wear is to be seen in a disadvantageous manner, resulting in a permanent use of the permanent provided with a closing rocker door. Over time, it may result in a no longer functional operation of the closing rocker as a result of wear-related wear, which is particularly of great disadvantage if the actually desired anti-panic automatic, d. H. the automatic locking or unlocking of the inactive leaf is no longer in proper working order.

Based on the above, it is therefore the object of the invention to propose a new device for automatic Verrieglung the passive leaf of a double-wing glass door, which is easy to assemble and wear-resistant wear is less sensitive.

To solve this problem, the invention proposes a device for automatic locking of the inactive leaf of a two-leaf glass door, in particular an all-glass smoke door, arranged with a frame side of the two-leaf glass door lock element which is formed pivotable in a plane lying transversely to the door leaf level of the inactive leaf.

The device according to the invention has an automatic locking of the inactive leaf via a locking element. This is arranged on the frame side, for example in a recess provided by the frame surrounding the wings of the door. In this case, the locking element is designed to be pivotable and / or movable, and indeed in a direction transverse to the door leaf level of the passive leaf level. The locking element can thus be pivoted to the inactive leaf and / or away from this and / or moved.

The peculiarity of the device according to the invention is in contrast to a closing rocker in that the locking element is not pivotally arranged in the manner of a rocker within the door leaf level of the inactive leaf, but the frame side is arranged pivotably in a lying transverse to the door leaf plane of the inactive plane. This embodiment has several advantages. On the one hand, the construction according to the invention, in contrast to a previously known from the prior art locking rocker allows more generous tolerances, both in the production and in the assembly. Proper functioning is therefore ensured in a wear-related wear of the individual components of the construction according to the invention in an improved manner. On the other hand, the construction according to the invention allows the entire locking mechanism to be able to accommodate a comparatively small amount of space, for example in the context of the all-glass door, because a movement of the locking element takes place transversely to the door leaf plane of the inactive leaf. In addition, the more extensive adjustment options and easier Zulaufen advantageous.

According to a further feature of the invention, a cooperating with the locking element actuator is provided, which is designed to be movable transversely to the door leaf level of the inactive leaf. This actuator is inventively provided to initiate the closing movement in the inventively provided locking element. The actuator is designed to be operable with the active leaf of the double-leaf all-glass door and is displaceably guided, for example, in a housing provided for this purpose. Thus, when the active leaf is closed, this results in an actuation of the actuator, which in turn acts on the locking element and thereby causes an automatic locking of the inactive leaf. Preferably, it may be provided in this context to form the actuator as a crank trap. In this way, a light and, above all, low-noise operation of the actuator and thus also of the locking element can be effected.

The locking element is arranged according to a further feature of the invention pivotable on an articulated arm, wherein the articulated arm interacts with the actuator. The construction according to the invention therefore consists of an actuator, an articulated arm and a locking element, wherein the actuator on the articulated arm and the articulated arm on the locking element acts. The locking element is pivotally mounted on the articulated arm, which advantageously allows a reduced size of the entire arrangement. For a further simplification of the overall construction, it can be provided according to a further feature to arrange the articulated arm pivotably on the housing for the actuator.

The locking element is formed according to a further feature of the invention as a curved lever. In the closed position, the locking element designed as an arcuate lever engages in a corresponding recess formed on the inactive leaf, wherein due to the arcuate configuration of the locking element, an undercut is created which ensures the locking of the inactive leaf.

The locking element is guided for a positionally accurate guide preferably in its movement of a guide element, which may be formed for example in the manner of a guide block, which provides a corresponding recess for guiding the locking element.

To reduce the wear-related wear, a sliding body may be provided on the articulated arm, which is formed on the actuator side and cooperates with the actuator.

With the device according to the invention an overall automatic locking of the inactive leaf of a double-leaf glass door is achieved, which is easy to install and easy to handle. Wear-related wear and tear interfere with proper functioning far less than with prior art devices.

Fig. 1 is to be taken from a known from the prior art per se two-leaf glass door 1. This serves to close a passage 16 formed in a wall 16. The all-glass door 1 has a moving leaf 3 and a passive leaf 2. These two wings are supported by a frame 17, wherein the active leaf 3 by means of corresponding hinges 18 and the inactive leaf 2 by means of corresponding hinges 19 are rotatably mounted on the frame 17.

Frame side of the two wings 2 and 3, a device according to the invention for automatic locking of the inactive leaf relative to the frame 17 is provided in a recess 20 thereof. This device according to the invention is in the FIGS. 2 to 8 shown in detail.

The inventive device for automatic locking of the inactive leaf 2 of the double-leaf glass door 1 has a locking element 5. This is in particular in the Figures 2 and 3 shown. The locking element 5 is formed in the manner of an arc and arranged in the final assembled state about an axis of rotation 11 pivotally mounted on an articulated arm 7, as this particular the Figures 2 and 3 can be removed. The articulated arm 7 is in turn arranged pivotably about a rotational axis 10 on a component to be designated as a holder 8, which relationship is likewise evident in particular from FIGS Figures 2 and 3 results.

The articulated arm 7 has two sections, wherein the first section may be referred to as a sliding body 12 and the second section as a lever arm 21. The lever arm 21 serves for the articulated arrangement of the locking element 5 on the holder 8, whereas the slider 12 cooperates with an actuator 6, which is formed in the preferred embodiment of the invention paging wing side as a crank trap. The actuator 6 is with respect to the plane of the drawing after the Figures 2 and 3 slidably formed in the longitudinal direction 22 and guided by the holder 8.

The holder 8 is mounted on the back side of a cuff plate 15, which closes in the finished-assembled state of the device according to the invention provided in the frame 17 for receiving the construction according to the invention recess 20 on the door leaf side. In the illustration after Fig. 2 this is best seen.

For a proper guidance of the locking element 5 in a transverse to the door leaf level 4 of the passive leaf 2 level, that is, with reference to Fig. 2 in sheet plane designed as a guide block guide member 9, which is also supported by the cuff plate 15. The guide element 9 has a recess 13 which receives the side of the wing-side part of the locking element 5 positionally reliable and displaceable. The recess 13 opposite also a recess 14 is provided for the locking element 5 in the cuff plate 15, which is penetrated in particular by the locking element 5 when the door is closed, such as Fig. 2 shows.

The cuff plate 15 is in a detailed view Fig. 4 removable. Fig. 4 further reveals a particular embodiment of the invention, according to which a Andruckeinstellung is realized. As the representation after Fig. 4 can be seen, the recess 14 in the cuff plate 15 for a passage of the locking element 5 is designed like a circle sector. This configuration makes it possible for the locking element 5 to guide the guiding element 9, which guides the edge of the wing, for adjusting the relative position of the locking element 5 relative to the inactive leaf 2, namely about the axis of rotation 23, like this Fig. 4 can be seen. For positionally secure positioning of the guide element 9 relative to the cuff plate 15, the guide element 9 with its axis of rotation 23 opposite end portion relative to the cuff plate 15 is fixed. This is used in the embodiment according to Fig. 4 a screw 25 which engages in a provided by the cuff plate 15 slot 26. As can be seen from the above illustration, the guide element 9 is pivotable in the direction of movement 27 about the axis of rotation 23, whereby a relative adjustment of the locking element 5 relative to the inactive leaf 2 is possible.

On the cuff plate 15 can otherwise according to the illustration according to Fig. 2 be formed in two parts. There are then preferably provided a first cuff plate for the holder 8 and a second cuff plate for the guide element 9. These two Stulpbleche are connected to each other in the pivot point 23 for the guide member 9 to the common cuff plate 15, optionally pivotally connected.

The actuator 6 preferably has - as already stated above - paging wing side over a crank trap. In particular, for reasons of noise insulation, this is an advantage. Articulated arm side, the actuator 6, as in the FIGS. 2 and 3 shown, have a sloping stop surface 28, against which the sliding body 12 of the articulated arm 7 slidably. For improved guidance of the slider 12 relative to the actuator 6 can also gelenkarmseitig the actuator 6, a cam 29 may be provided which protrudes from the stop surface 28 and engages in the ready-assembled state in a correspondingly shaped guide groove of the slider 12. Thanks to this cam-guide groove training an unintentional displacement of the slider 12 is prevented relative to the actuator 6 in a direction transverse to the rotational movement direction of the articulated arm 7 about the pivot point 10 direction.

The operation of the device according to the invention is the following:

In the open state of the active leaf 3 and passive leaf 2, the construction according to the invention is in its open position as in Fig. 3 is shown. This open position can be positively trained, for example, by means of corresponding spring elements, for example by a spring element on the holder 8 on the one hand and is arranged on the hinge arm 7 on the other hand and strives as a tension-spring element, the articulated arm 7 with respect to the plane of the drawing Fig. 3 to turn to the left about the pivot point 10, so that the locking element 5 from the closed position to Fig. 2 in the open position after Fig. 3 is transferred.

Now if the inactive leaf 2 on the frame 17 is properly connected and the active leaf 3 is closed, this leads to the active leaf 3 ascending against the pitch side, for example, as a crank trap actuator 6, as in Fig. 2 is shown. This driving leads to the fact that the actuator 6 shifts in a provided by the holder 8 guide in a direction transverse to the door leaf level 4 of the passive leaf 2 level, ie with respect to the plane of the drawing Fig. 3 moved away from the moving leaf 3 upwards. This displacement movement of the actuator 6 causes the articulated arm 7 is rotated about the axis of rotation 10, which in turn leads to a rotational movement of the locking element 5 about the joint axis 7 and the locking element 5 common axis of rotation 11. As a result of this twisting movement, the locking element 5 pivots in an in Fig. 2 not in detail shown recess of the inactive leaf 2, which leads to a locking of the same by means of the locking element 5 relative to the frame 17. <U> REFERENCE LIST: </ u> 1 Glass door 21 lever arm 2 Fixed leaf 22 longitudinal direction 3 leaf 23 axis of rotation 4 Door leaf plane 24 end 5 locking element 25 screw 6 actuator 26 Long hole 7 articulated arm 27 movement direction 8th holder 28 stop surface 9 guide element 29 cam 10 axis of rotation 11 axis of rotation 12 sliding 13 recess 14 recess 15 retaining plate 16 wall 17 frame 18 hinge 19 hinge 20 recess
