Abstract

The invention relates to an automatic lock for doors or the like, having a latch (2) which is subject to the action of a latch spring, and an arresting element (12) for arresting a driving-rod slide (13) which is forced into its arresting position, wherein the driving-rod slide (13) controls at least one bolt (3) in the locked and unlocked position of the same, and wherein the driving-rod slide (13) is released, and the bolts (3) pass into the locked position, by virtue of a trigger (8) of the arresting element (12), said trigger projecting on the lock-case-front side and striking against the striking plate. In order to achieve a safe release with low production outlay, it is provided that the trigger (8) is a two-armed pivot lever, whose first arm (9) is formed by a sensing arm (10) and whose second arm (11) forms an arresting element (12) for the driving-rod slide (13) and is received in the slotted latch bolt (14).

Description

lock

The invention relates to a lock according to the preamble of claim 1.

Such locks are already known. DE 2417322 A shows a latch bolt which has a locking lever and a trigger slide. The locking lever is urged along with the latch in the direction of the strike plate and thereby carries the

Shutter release with it. If this comes into contact with the strike plate, the locking lever can be pivoted to a sliding angle of the trigger slide effective in a position in which it no longer engages behind the edge of the passage opening in the face plate and the trap continues to occur. The embodiment provides that the case is rotatably guided in a tube and therefore can be used left and right.

EP 0431369 A2 shows a case in which the locking element is pivotally mounted in the case and has two locking lugs, which engage behind the face-plate. The release of the first latching lug takes place by applying a triggering projection on the striking plate, whereby the blocking element is pivoted and allows the latch to protrude into the first position. As a result, the trap is further preconnected by the action of the latch spring and the second latch is effective.

From DE 10201 1089418 A1 a trap corresponding to the function of

EP 0431369 A2 is known, in which it is provided that a bump is attached to the pivotable trigger, which is to complicate a manipulation. DE 20201 1001842 U1 shows a latch bolt according to the aforementioned DE 10201 1089418 A1. Here is the use of a reversible trap in the

Foreground.

DE 202012009802 U1 discloses a mortise lock with a lock housing, a latch cooperating with a latch and a latch. On the case is a triggering device for cooperation with the strike plate intended. The triggering device is coupled to the latch in such a manner that when the triggering device interacts with the strike plate, a latch release lever for releasing the latch and for subsequently extending the latch out of the lock housing is actuated. The triggering device has a displaceable strike plate release lever for cooperation with the

Strike plate and a toggle lever on. The striker release lever causes a displacement due to the interaction with the striker plate

Pivoting the articulated lever and leads to a linear adjustment of the latch release lever and the extension of the bolt.

A disadvantage of the aforementioned prior art is that the release mechanism is comparatively small and the assembly is therefore complicated. In addition, the filigree designs after a period of time and concomitant use in their function inaccuracies and errors arise.

From DE 202015000106 U1 an automatic lock according to the preamble of the main claim has become known in which a trigger located on the back of the case is part of a coaxial to the direction of rotation shaft which engages with a locking element on a drive rod slide and releases it in the activated position of the trigger , Due to this configuration, the design of the case is expensive. For that is the use at one

Multiple locking possible.

A disadvantage of all mentioned embodiments, it is also that with the

Meeting the trap on the strike plate the bolt regardless of the

To anticipate the need situation. As far as only the case occurs according to their case function, the door can be opened remotely, for example via an electric door opener. However, if the lock is constructed in the manner of a latch bolt lock, the latch, after actuation of the trigger, enters its locked position and is secured against being pressed back. Therefore, the combination of an electric door opener and a latch bolt lock is not possible. If, in addition to the case, further latches are actuated, eg in secondary lock cases, remote operation is only possible with an electric lock drive. Therefore, there is a need for a lock whose automatic function can be selectively switched on or off. For this purpose, a change is provided in EP 0682167 B1, which has a

Coupling on the pusher nut acts on the trap. For this purpose, the pusher has a separate lever, which shifts the trap, as soon as the pusher is set in motion over the change, in its retracted position. Thus, the case can be permanently held in their retracted position, this mortise lock on a Fallenarretiereinrichtung, which consists of pairing a return path on the change with an associated mounted on the lock case lock stop, the lock stop moves against the movement possibilities of the change in the return path of the return path lock, to prevent the change on his way back to the base position can go back. The barrier stop consists of a two-armed lever which is mounted as a rocker stationary on the lock case and is offset by the cam of the lock cylinder in rotation in the closing direction in its locking position. In this mortise, the setting of the trap is done via a

Twist the pusher nut until the latch is in its retracted position and then activate the lock stopper via the key. For this purpose, the key must be turned in the closing direction, so that the barrier stop is shifted with the associated arm in the return path of the return path barrier. Although such a mortise lock has a complicated structure, and can not be used for doors with increased safety requirements, since only one bolt and the trap are provided.

The lock described in DE 19748444 A1 has a latch which is mounted in a latch window of a face-plate rail. The trap can be of one

Fallenvortrittsstellung in which the largest part of the case head is located in front of the faceplate, are retracted into a Fallenrückzugsstellung in which the case is completely retracted into the trap window. On the back of the faceplate is a trap lock in the form of a pitch disc, which can be switched back and forth by turning on an axis of rotation between a locking position and a release position, this case lock can hold the case in the back-closed position.

From DE 4015881 C2 a lock is known in which the trap in a

Fallenvortrittsstellung is blocked by means of a lever arm. DE-PS 691398 discloses a latch lock in which the case via a knob is retractable so far that a connected to the knob pin, which acts on the latch on the tail tail in a control slot spring loaded behind a

Locking projection occurs, so that the trap can occur again only by pressing the knob.

DE 89091 19 U1 shows a lock in which the case by the change by means of a key operation by a differential range is further retractable than by means of a handle operation. Within this difference range is a

Locking device for the trap in lock-engageable and holds the trap in

withdrawn position.

DE 102007044324 B3 has the subject of a lock which, for the purpose of catch locking, provides a locking member which provides an actuating section to be actuated from the forend rail and a locking section engaging the latch tail.

EP 0801 193 B1 shows a mortise lock with a latch which has a locking latch in the latch head. The locking bolt can be moved in retracted case behind the faceplate and thereby prevents the passage of the case.

In contrast, the operation of the mortise lock according to EP 0410122 B1 is relatively simple, since there the retracted over the change case by simply pressing an accessible from the face side of the mortise ago

Pressure bolt is locked. However, this mortise has a relatively complex structure, since in particular the change must be made in two parts. This mortise lock is incompatible with the requirements for a secure locking of a multi-point lock. It is an object of the invention to achieve a safe release with low production costs and to remedy the aforementioned deficiencies.

To solve the invention provides that the trigger is a two-armed pivot lever whose first arm is formed by a sensing arm and the second arm a Locking element forms for the espagnolette and in the slotted

Trap tail is added.

A further development provides that the vertical extension of the probe arm corresponds to about 50% of the trap height. By the measure, the probe reaches a

comparatively large dimension with respect to the trap and therefore also cooperates with a frame-side trap inlet opening when it is dirty, has a not exactly seated insert or has a Feilnase. A Feilnase is a centric projection in the trap opening, in which the trap in

supporting position and which can be adapted to adapt a desired pressure by means of a file. These Feilnasen are centrally mounted in the trap opening, which in particular after a certain time and thus related positional shift of the trap within the trap opening can cause the trigger passes by the Feilnase. In addition, the trigger can be easily integrated into the trap and stored by this feature combination.

A particular embodiment provides that the espagnolette is fixable in its unlocked position on the Steckrad. By this measure, the case can be fixed in a retracted position on the key and remains ineffective, for example, if the door equipped with it should remain unlocked in a daytime operation. This function can only be performed by an authorized person by means of a key provided to him.

It is advantageous if the pressure piece can be fixed in a determined via the pin wheel Fallenrückzugslage.

It can still be provided that the Steckrad engages under a latched back over a pusher case the pressure piece locking. A further embodiment provides that the pressure piece acts on the latch tail via a pivotable latch lever.

Further advantageous embodiments will be apparent from the drawings. 1 shows the main lock case from above in the unlocked state, Fig. 2 shows the main lock case, as shown in Fig. 2 without espagnolette from below, Fig. 3 shows the main lock case of FIG. 1 in an isometric view in

Espagnolette and

Fig. 9 is a detail of the Steckrades and the pressure piece according to the position shown in Fig. 8.

In the case of FIG. 1 to 3 illustrated main lock box 1, a latch 2 and a latch 3 is provided. To operate the lock next to a follower 4, a non-illustrated lock cylinder is provided, which is seated in a lock cylinder receptacle 5 and cooperates with a pinwheel 6, 7.

The trap 2 includes a trigger 8. The trigger 8 is two-armed

Swivel lever designed whose first arm 9 is formed by a sensing arm 10 and the second arm 1 1 forms a locking element 12 for a drive rod slide 13 and is received in the slotted latch tail 14. The pivot lever is pivotally mounted about an axis 15 and a spring 16 generates a restoring force. It can be seen that the vertical extent of the sensing arm 10, designated as dimension 17 in FIG. 7, corresponds to more than 50% of the trap height 18. The slot 19 for receiving the arm 1 1 is dimensionally closely matched in width 20 to the arm 1 1. The interaction is in conjunction with FIGS. 3 and 4 can be seen. Starting from an unlocked and partially opened wing, the lock shown in Fig. 4 with the trigger 8 comes to rest against a locking plate edge of the associated frame. This can also be an AT piece or an electric door opener. If the trigger 8 is pivoted counterclockwise in FIG. 7, then the arm 11 completely plunges into the slot 19. As a result, the blocking element 12 is displaced out of the displacement region of the end edge 21 of the blocking tab 22 of the espagnolette 13 and releases it. The end of the espagnolette 13 is, as shown in FIG. 5 U-shaped and the latch tail engages in the space of the Espagnolette 13 and the locking tab 22 which is spaced from the planar control surface 23 of the espagnolette 13 via a projection 24. The control flap is attached as a rectangular sheet metal section on the opposite of the control surface 23 sublime executed approach 24. The espagnolette 13 has a further locking edge 25 which, relative to the longitudinal edges, along the

Espagnolette 13 is displaceable according to the end edge 21 is arranged. Due to this arrangement, the locking element 12 can be locked in a rotated by 180 ° case 2 with the locking edge 25 instead of the end edge 21

interact.

Is the fixation of the espagnolette 13 repealed, this is through

Gravity or Federkraftbeaufschlagt shifted in Fig. 2 down. An engaging in the oblique slot 26 pin 27 of the bolt 3 displaces this from the lock case 1 in its locking position of FIG .. 3

In order to unlock the lock again, it can be pivoted clockwise (FIGS. 1 and 3) via a pusher which engages in the pusher, whereby the nut arm 28 engages under an edge 13 'of the espagnolette 13 and displaces it upwards. As a result of this upward movement, the latch 3 is retracted into the lock case 1. The case 2 is moved back over a latch lever 29 which is pivotally mounted about an axis 30 on the castle ceiling. To this end, the nut arm 28 engages the latch lever 29 on the underside of the latch lever 29 and pivots clockwise when it moves upward (FIG. 1). Alternatively, the lock can be unlocked via a cylinder operation. In this case, the inner pinwheel 6 of the two-part pinwheel executed engages under the drive rod slide 13 and moves it upwards. The espagnolette 13 engages with a rivet in a Langlochausnehmung the pressure piece 31 and takes this in the upward movement with upwards. The pressure piece 31 comes into abutment against the latch lever 29, the position of which was determined by the stop on the latch tail 14 and a latch spring attached thereto. The latch lever 29 pulls the case 2 back. If the key operation is completed, the latch lever 29 is pivoted counterclockwise again, which is done by the nut springs 32 acting on the pusher 4. The trap 4 enters the ready position before and the espagnolette 13 is on the blocking element 12 in his

Open position held.

In addition to the above-described functions for locking and unlocking further operating conditions are adjustable due to the arrangement. For a first variant, the unlocked lock with the door open, so pressed without contact of the trigger 8 with a strike plate with the key. The key operation takes place in Fig. 2 in the clockwise direction and corresponds to a non-automatic lock one

Pre-closing the bolt. In the embodiment shown in Fig. 2, the lower pinion 7 is pivoted clockwise under the espagnolette 13 on the cylinder actuation with the key. This has to a projecting support projection 33, as illustrated in Fig. 8. At the Steckrad 7 a radius 34 is mounted, which engages under the support lug 33. The radius 34 merges into a flat 35. Due to this measure, the espagnolette 13 can not be displaced downwards and upon actuation of the trigger 8 remains in consequence of

Undergrip the Steckrades without effect, since the espagnolette 13 is fixed in its unlocked position on the pin wheel 7. The lock having the door can therefore reach the plant to the frame and is locked only on the case 2. Therefore, by using an electric door opener, the door can be operated remotely. FIG. 9 shows the position of the alternating pressure piece 31 in FIG

Position of the lock cylinder according to FIG. 8. The alternating pressure piece 31 is located in the swivel range of the upper plug wheel 6 and can slide along an edge 36 past it. A change operation is still possible. Another function of the lock arises when unlocked and

Partially open door, that is actuated without contact of the trigger 8 with a strike plate or the like of the pushers and at the same time a key operation takes place. This has the consequence that the apparent in Fig. 1 position of the pressure piece 31 and the latch lever 29 can be achieved. Fig. 1 shows the pusher in the unactuated state, in which the pawl 6 engages in retracted trap over the cylinder by precluding the raised over the pusher 4 pressure piece. If the pressure piece 31 is fixed on the pinwheel 6, the pusher nut 4 can again their

Normal position. Due to the fact that the Steckrad 6 at one over a

Pusher 4 withdrawn case the pressure piece 31 engages locking, the case 2 can no longer protrude over the Stülp and remains in the retracted position. Thus, the trigger 8 is ineffective. This switching position may be advantageous if the door should remain unlocked for a short period and / or is pressed by a door closer anyway to the frame.

A method of actuation therefore comprises establishing an unlocked position of the espagnolette, actuating the lock by means of the cylinder with or without actuation of the trigger.
