Description

Closing and opening system for securing a hinged door leaf in a building opening against unauthorized opening

The invention relates to a locking and opening system for securing a hinged door leaf in a building opening against unauthorized opening consisting of a unit both for closing a hinged door by means of a door lock with an automatic locking bolt actuation and the latch bolt release and unlocking the automatically triggering locking bolt Assembly for closing a door leaf via a remote-controlled electromagnetic door opener.

There is no comparable with the subject of the invention comparable and stimulating to the expert acting state of the art. There are only individual devices known that can not solve a technical problem described below and existing. An obvious state of affairs has not arisen because one of ordinary skill in the art has considered a problem underlying this invention intractable. For locking lockable door wings locks are known which have a handle operable by a door latch latch bolt and a by a key or the like. Operable movable locking bolt. Both the latch bolt and the locking latch engage in perforations of a striking plate. The return of the locking bolt in the unlocked position allows opening of the door lock by means of a door handle.

If a not closed by the lock latch, which can be opened only on one side, is to open this lock either mechanically by means of a key directly or by a remote-controlled electromechanical door opener, the electromechanical door opener in a to be closed opening enclosing door frame in the field of Fallenlochung replacement is arranged for this in the strike plate. The known electromagnetic door openers have a pivotable and lockable, provided with a stop bar door latch. The release or blocking of the door opener trap via an electromagnatischen drive in the door opener. By releasing the door latch, the latch bolt of the door lock engaging therewith can move the pivotable stop bar of the door latch latch connected to the door latch case out of the locked position, thereby releasing the latch latch of the door latch and allowing the door to open.

A hinged door leaf can only be opened via an electromagnetic door opener if the lock serving lock has not been locked on the lock bolt. The locking bolt is not engaged with the bolt holes in the strike plate, but the closed and locked only on the latch bolt door can be opened more easily by force. The one forceful opening by the movably arranged door opener trap of the door opener opposable force is too low for this purpose. This disadvantage has the effect that a door lock locked via a latch bolt can only be used for a door in an area without a high security requirement.

There are so-called Fallenriegelschlösser with an automatic latch actuation known. Upon reaching the closed position of a door, a release lever arranged in a latch bolt, which on one side projects beyond the latch bolt on the non-wedge-shaped surface, hits against a blocking edge of a strike plate provided in a door frame or the frame perforation or a strike plate perforation. This leads to the actuation of the release lever in the latch bolt and thus to the actuation of the locking bolt, which is pushed back during the door closing and then locks in the Fallenlochung. The release lever is actuated in the latch bolt and the automatic latch moves into the bolt holes and thus into a locked position. The opening of a closed latch bolt lock takes place by means of a door handle or by means of a lock cylinder or a lock key. It is withdrawn by this mechanical operation of the latch bolt and at the same time tensioned a ejection spring for the automatic latch and fixed in this tensioned position. A disadvantage of these latch bolt locks is that they can only be mechanically operated on site with mecha - A -

can be unlocked, which contributes to the safety of a castle only within limits. Also, an operation of this latch bolt lock by means of an electromagnetic door opener is not possible.

The aim of the invention is on the one hand to increase the degree of security of a lock lock and on the other hand, that this can be unlocked via a remote control means of an electromagnetic door opener.

The invention has for its object to provide a closing and opening system for a hinged door consisting of a unit both for closing a hinged door with an automatic locking latch actuation and latch release and unlocking the automatically triggered locking bolt of the unit for locking a remote-controlled electromagnetic To develop door openers.

According to the invention this object is achieved by the disclosed in claim 1 technical means. The disclosed in the dependent claims technical means serve to further embodiment of the invention.

Fig. 8 shows a structural unit as shown in Figure 2 with a proposed kinematic transmission for actuating a three-point lock.

In one in a door frame 1 pivotally mounted door wing 2, one, one-sided mechanically operable door lock 3 is provided from a direction of an unprotected room, extending from one direction to a sheltered room with the help of a provided in the door frame 1 electromechanically actuated door opener 4 open.

The door lock 3 is designed as a box lock and has an upper latch bolt 5 with a tumbler 6, designed as a second latch latch release element 7 for a locking bolt 8, the locking bolt 8 and an opening latch 9. The upper latch bolt 5 can be actuated together with the tumbler 6 and simultaneously with the locking bolt 8 by means of a door handle, not shown. Upon actuation of the door handle, not shown, the rotational movement of a nut part 10 is connected to a double lever 11 connected thereto; 12, the two at a defined angle to each other extending lever parts 11; 12 has transmitted. The upper lever part 11 serves to act on the latch 6 provided with the latch bolt 5, which is under a force of a compression spring 13. The lower lever part 12, which is under the action of a return spring 14, is for Operation of the locking bolt 8 is provided. The lower lever part 12 acts with its free end 15 on an upper part lever 16 of a two-armed clamping lever 17 for the locking bolt 8 a. As a result, the clamping lever 17 is moved against the force of a torsion spring 18 about a vertical axis 19 and a driver pin 20, which is provided in the lower part lever 21 of the clamping lever 17, slides over a cantilever-shaped stop 22 of a spring-loaded pawl 23 and engages behind this stop 22nd The pawl 23, which is displaceable against a compression spring 24, is arranged within the closing collar 8, specifically in a guide groove 25 running transversely to the latch 8. By a manual tensioning of the clamping lever 17 by means of the door handle, not shown, via the lower lever part 12 of the actuating lever 11; 12, the locking bolt 8 is brought into a release position. In the tensioned state, the upper partial lever 16 of the clamping lever 17 engages behind a stop lug 26 of an angle stop 27 rotatably mounted on the opening latch 9. By closing the door leaf (2), the trigger element 7 and thereby simultaneously the angle stop 27 is actuated. As a result, the stop lug 26 is brought out of the engaged position, whereby the upper part lever 16 of the clamping lever 17 is released. The driver 20 of the clamping lever 17, which engages behind the stop 22 of the pawl 23 in the tensioned state, will now move the locking bolt 8 in the closed position, ie this moves out of the lock case and is in an engagement position within a bolt holes 28 in the face plate 29 in the door frame 1 moved in.

The locking bolt 8 is fixed in this closed position by a bolt lock 30 in the door lock 3 in its position and thus protected against violent opening out of the closed position. In the closed position, a blocking stop 31 of the bolt lock 30, caused by the force of a compression spring 32, falls behind a sliding guide 33 of the locking bolt 8, whereby the sliding guide 33 engages behind the locking catch 31.

In a triggered by an external actuation of the opening bolt 9 return of the locking bolt 8, the locking bolt 30 is acted upon by a release arm 34 of a two-sided release lever 35, whereby the bolt lock 30 is actuated and the catch 31 is brought out of engagement with the slide 31. After release of the bolt lock 30 of the locking bolt 8 is guided by the force of a tensioned compression spring 36 in an initial position of the unlocked door lock 3 back.

The same effect achieved by operating the opening riegeis 9 is also effected by the operation of a door handle, not shown. By the with the

Nut part 10 connected upper actuating lever 11, the upper latch bolt 5 is brought into the open position and thereby actuated by the return of the latch bolt 5, a stop arm 37 of the two-armed release lever 35.

The tumbler 6 is rotatably mounted within the latch bolt 5 and a pivot axis 38 extends transversely, d. H. perpendicular to the direction of movement of the latch bolt 5. The

Tumbler 6 is within a recess 39 of the trap The tumbler 6 consists of a two-armed lever which is arranged tiltable about an axis of rotation 38 within the latch bolt 5. The tumbler 6 has a hook nose 40, which terminates flush with a front boundary surface 41 of the upper latch bolt 5 in the direction of movement towards the door opener 4. In the closed position of the door 2, the hook nose 40 of the tumbler 6 projects beyond a lower sliding surface 42 of the upper latch bolt 5 and the hook nose 40 of the tumbler 6 is located in the door frame 1 and provided with a hook receptacle 43 stop bar 44 a door latch of an electromagnetically actuated door opener 4 engaged.

With this, the latch bolt 5 is withdrawn while the hook-shaped tumbler 6 is actuated at the same time, ie provided with a hook nose 40 tumbler 6 is raised and disengaged from the Hook receptacle 43 of the stop bar 44 of the door opener 4 brought. Trained as a double lever tumbler 6 has on its hook nose 40 remote from the lever side 45 on a wedge-shaped actuating surface. With actuation of the upper lever part 11 by a door handle, not shown, on the nut part 10, the tumbler 6 is raised with the return of the nut part 10 connected to the upper lever part 11 and thus the tumbler 6 against the force of a compression spring 46 and thus out of engagement brought the hook receptacle 43 on the stop bar 40. Subsequently, the upper latch bolt 5 can be moved. An external opening of the locked door lock 3 of the inventively designed closing and opening device by means of remotely operated door opener 4, by releasing, ie unlocking the Anschlagleise 44. After release of the stop bar 44 of the door latch latch it is pivoted about a vertical axis, not shown. In the stop bar of the door opener trap is a squeezer 47. This moves with the stop bar 44 of the door opener latch out of its position and indeed on a circular path. In this case, this actuates the opening latch 9 of the door lock 3, which is positioned in opposition to the squeezer 47 in the door opener 4. After contact between the squeezer 47 and the opening latch 9, the latter actuates the stop arm 37 of the release lever 35 designed as a double lever and the bolt lock 30 is actuated via the release arm 34. Thereafter, the locking bolt 8 moves by the force of the compression spring 36 in the locking bolt 8 in the starting position and the door can be opened without the use of mechanical actuation means.

The door opener used here in the closing and opening device designed according to the invention is an electromagnetic door opener 4 provided according to the invention with a squeezer 47, in which the position of a pivot axis, not shown, for the door opener latch for receiving the stop bar 44 has been changed.

Both by the formation of the door lock 3 and the door opener 4, a locked door lock 3 of the inventively designed closing and opening device by a remote control without using a door key or by the use of a lock cylinder are opened. However, it is also possible with slight changes to provide the door lock 3 with a lock cylinder, not shown, so as to correspond to the habits of the user of such door locks 3. If a lock cylinder is used, deleted in the door lock 3 of the release lever 35, since the lock bolt 8 is acted upon by the lock cylinder.

If the inventively designed closing and opening system is used in conjunction with a triple locking of the door leaf 2, not shown, with respect to the door frame 1, the locking bolt 8 of the door lock is provided with a drive member 48. This drive member 48 is part of a wedge thruster with perpendicular to each other linear guides of the drive member 48 and an output member 52 for the actuators 49 of the three-point lock. The drive member 48 engages with a sliding block 50 connected thereto in a positive guide 51 of the output member 52 a. The output member 52 is connected to the actuators 49 of the three-point lock and is arranged in the lock case 53 below the locking bolt 8. The positive guide 51 consists of a recess with a defined sliding angle 54, which is based on experience 45 °. With the automatic operation of the locking bolt 8 during the closing operation of the door leaf 2, the output member 52 and thus the actuators 49 are actuated for the three-point locking by the moving in the Zangsführung 51 sliding block 50 of the drive member 48.
