Description

Technical area

The invention relates to a lock comprising a housing, a spring-loaded latch, a movable by an actuable push rod latch and cooperating with a strike plate triggering element which protrudes in the starting position with a projection in the path of movement of the push rod and blocks it in the unlocked position.

State of the art

Panic locks of this kind, in which the bolt automatically extends together with the latch when a door is slammed, have been known for a long time. A trigger element, in the form of a slider or a lever, often serves to block the push rod in the lock mechanism until the trigger element is pressed by the strike plate into the housing of the lock and thereby releases the push rod, which pushes out the bolt in a row.

In another known variant, the release levers are not slidable into the housing slides or levers, but have outside on the forend protruding laterally pivotable projections, which cooperate with corresponding recesses in the strike plate. An example of such a castle is in the EP 2287426 A shown. In this case, the triggering element has a laterally projecting beyond the forend bracket, which cooperates with a corresponding recess in the strike plate. A disadvantage of this design is that the trigger element is elaborately constructed of different parts and the protruding bracket must be rebuilt depending on the use of a left or right hinged door.

The DE 8902476 U shows a variant in which the projecting beyond the forend part is a displaceable in a transverse slot in the forend pin, which cooperates with a corresponding lever mechanism in the lock housing. Although this variant can be used without conversion on the left and on the right hinged doors, but the structure is still complicated and error-prone. The provision of the pin exactly to a middle position in the hole via a tension spring on the inner lever leads in practice to a very inaccurate restoring behavior, whereby the locking security of the castle is impaired. Also, this variant can easily be misdirected in an accidental passing the release lever.

Presentation of the invention

The aim of the present invention is thus to provide a lock which eliminates the above-mentioned disadvantages, and in which the protruding from the forehead part of the release lever is simple, which has a high locking security and used without modification for left and right hinged doors can be.

This object is achieved in that the trigger element is pivotally mounted by means of a perpendicular to the forehead standing in the forend held axis, wherein an inner lying in the housing end portion of the trigger element has the projection which blocks or releases the push rod, and wherein an outer over the Stulp protruding end portion is designed as a two-armed lever whose lever arms are inclined in the starting position of the trigger element substantially away from the axis of rotation in the direction of the respective side edges of the forend and in the end position, in which one of the most laterally projecting portions of the lever arms with a corresponding recess cooperates in the strike plate, are substantially as far pivoted in the direction of Stulpmitte out that the projection on the inner end portion is out of engagement with the push rod. It is thereby possible to provide a very simple triggering element, which converts the lateral linear force, which acts on the trigger element on the striking element when the outer end portion strikes, into a rotational movement which causes the push rod to release inside the lock housing. As a result, the latch is automatically moved by the downwardly moving push rod in its extended position. The push rod can be biased in the direction of the blocking position by means of a spring, or be acted upon only by gravity.

According to a further feature of the invention, it is provided that the initial position of the triggering element corresponds to an end position of the pivoting path of the triggering element. This ensures that the triggering element can always assume a specifically defined starting position, in which blocking of the push rod is possible. The locking security is thereby increased significantly.

It is a further feature of the invention that the lever arms of the outer end portion of the trigger element are formed around the axis of rotation point-symmetrical. The concrete geometric design of the lever arms can be arbitrary, it being important to ensure that the respective acting ends of the lever arms are seen from the axis of rotation from point symmetry, so that the lock is equally actuated both in a left as well as a right stop. Depending on the stop, either the upper or the lower lever arm strikes the recess in the striking plate, as a result of which the triggering element is actuated.

Furthermore, it is a feature of the present invention that the triggering element is integrally formed. This embodiment is preferred, as this allows a very cost-effective design, wherein the trigger element is simply inserted into a corresponding hole in the forend.

According to a further feature of the invention, it is provided that between the outer end portion of the trigger element and a bearing section located in the forend a distance portion is provided whose thickness corresponds at least to the thickness of the forend and serves as a guide of the triggering element in the forend.

The thickness of the outer end portion of the trigger element is dimensioned so that the gap width between faceplate and frame is bridged in the closed position and a secure actuation of the trigger element is ensured by the recess in the strike plate. Since a gap of a few millimeters between forend and frame remains in each door even when closed, it makes sense to provide this outer end portion with this thickness to safely Make sure that the trigger element can always engage in the strike plate.

Finally, it is a feature of the invention that at least one additional blocking element is provided for blocking the bolt in the extended position, which can be actuated, for example via a lock cylinder. Thus, the unwanted retraction of the bolt by pressing the trigger, which acts on the push rod, can be prevented.

Way (s) for carrying out the invention

That in the Fig. 1 to 6 The lock shown has a housing 1, which is shown open in the illustrations. On one side of the housing 1 is the face plate 2, which is provided with different openings for the case 3, the latch 4, and the trigger element 5. The latch 3 can be retracted against the force of a spring via a nut 7 and a door handle (not shown) attached thereto. On the nut 7 is further a driver 14, which in a corresponding opening 15 in the Push rod 6 engages, whereby the push rod can be moved by means of the door handle on the nut 7 in the unlocked upper position. The push rod 7 is further connected via a slotted guide 20 with the latch 4, whereby it can be pushed out or retracted during movement of the push rod. In addition, a recess 8 is provided for receiving a lock cylinder, which actuates a locking element 9, which can block the latch 4 in its extended position.

In the Fig. 1 and 2 the lock is shown in that position, in which the nut 7 is in neutral position, the latch 3 is extended and the latch 4 is in the retracted position. A trigger element 5 has at its inner end portion 11 on a projection 16 which projects into the path of movement of the push rod 6 and prevents them from moving downward. The trigger element 5 extends through the face plate 2, wherein the outer end portion 10 is formed as a two-armed lever. In the position according to Fig. 1 and 2 is the trigger element 5 in its initial position, in which position the two lever arms 12,13 are pivoted in the direction of the respective Stulpseitenkante 21, 22 out. The upper lever arm 12 is the first Stulpseitenkante 21 and the lower lever arm 13 of the second Stulpseitenkante 22 inclined.

If the door is now closed, then the outer end portion 10 of the trigger element 5 enters a corresponding recess of the strike plate, whereby the trigger element is pivoted about its axis of rotation 18 perpendicular to the forend. Depending on how the door is struck, either the upper lever arm 12 or the lower lever arm 13 strikes the rear wall of a corresponding recess in the strike plate and causes the triggering element to pivot. As in Fig. 2 this corresponds to a counterclockwise rotation of both left and right hinged doors.

As soon as the door is completely closed, the release element assumes the position according to Fig. 4 a, whereby the projection 16 of the inner end portion 11 with the push rod 6 is disengaged and the Push rod, which is biased by a spring towards the locking position, can move down. As a result, the latch 4 is pushed out of the push rod due to the link guide 20 and takes the position according to Fig. 3 one.

If the push rod 6 is moved back into the upper position by the door handle, both the latch and the latch is retracted and the trigger member can move back to the starting position, where the projection 16 of the inner end portion 11 again enters the path of movement of the push rod 6 ( Fig. 5 and 6 ).

In the FIGS. 7 and 8 a trigger element is shown in detail view. At the inner end portion 11 is the projection 16 which blocks the push rod 6 in the upper position. Furthermore, a recess is provided in which the spring 17 is mounted, which biases the trigger element 5 against its initial position. The starting position is an edge-side stop of the movement path of the trigger element 5. The outer end portion 10 is formed as a two-sided lever with two point-symmetrical lever arms 12,13. To guide the forend 2, a spacer portion 19 is provided.

The thickness of the outer end portion 10 of the trigger element 5 is dimensioned so that the gap width between face plate 2 and frame is bridged in the closed position and a safe operation of the trigger element 5 is ensured by the strike plate.
