Description

LOCK

Technisches GebietTechnical area

The invention relates to a lock for a door or a window comprising a housing, a stulpseitig push-out latch disposed therein and a latching mechanism operatively connected to the latch, which can be actuated by a lock cylinder via a locking lug, for example.

Stand der TechnikState of the art

Conventional cylinder locks have long been known. One object of such locks is to continuously improve the connection between the striking plate and the latch in order to counteract attacks, such as the levering of a door or a window.

One way to achieve an improved connection between latch and strike plate is to provide pliers-shaped latch. Such locks, for example, often used in motor vehicles, wherein for actuating usually a supporting power drive is available or the mechanics of the bolt is constructed according to complicated. Such a lock is disclosed for example in DE 8902505 U1.

Darstellung der ErfindungPresentation of the invention

It is therefore an object of the invention to provide a lock for a door or a window, which eliminates the disadvantages mentioned above and creates a secure connection between a latch and a strike plate. The production costs should be kept as low as possible by using mostly existing components of known mortise locks.

This object is achieved in that the latch has a lockable with the lock mechanism substantially normal to the forend slidable locking plate on which are mounted rotatably on the faceplate end two pawls, wherein the pawls each have guide pins which are guided in corresponding arranged in the housing scenes are, which serve the displacement of the pawl from a retracted position to a closed position, and wherein the pawls have at their free ends facing each other hook-shaped recesses which engage in the closed position with a closed door or window a bolt arranged in a closing piece. By this measure, a bolt can be created in a very simple manner, which provides a much better connection to a striker than conventional latch and thus leveraging a door much more difficult. Compared to a conventional lock, the structure differs only in the provision of the locking plate arranged thereon pawl and arranged in the housing scenes. The production costs can thus be kept low, since only a few parts have to be modified. For the pushing out of the bolt no higher force is necessary than in a conventional latch, the backup can be done in the closed position in the usual way by a backup in the lock mechanism.

It is a further feature of the invention that the pawls are arranged on opposite side surfaces of the locking plate, and that the arranged in the housing associated with the respective pawls scenes are also arranged on opposite sides of the housing. This represents a particularly simple way of latch construction.

It is a further feature of the invention that the pawls are formed around its pivot point around as a two-sided lever, wherein the hook-shaped recesses are arranged on a lever arm and the guide pins are arranged on the respective other lever arm. This makes it possible in a very simple manner, even with a very short movement path of the locking plate ensure that the locking hooks are sufficiently far out of the forend to securely grasp the bolt arranged in the locking piece.

According to a further feature of the invention, it is provided that the lock has a latch assembly which is actuated alternatively via a nut or a lock cylinder, wherein for the operative connection between the lock cylinder and the latch assembly, a displaceable change lever is provided, which pivotally mounted on the closing cylinder end Operating lever has, which is pivoted by cooperation with a bolt on the locking plate, preferably arranged on the locking bolt in the retracted position of the bolt in the direction of the lock cylinder, whereby the free end of the actuating bracket projects into the path of movement of the locking lug of the lock cylinder. Since locks usually not only have a bolt with lock cylinder, but also a trap assembly which can be actuated for example by means of a door handle on a nut, it should also be possible to operate this case arrangement by the lock cylinder by means of a change lever. For multi-speed locks or even with a small amount of space within the lock housing, it is therefore necessary that the change lever has a pivoting actuating bracket, which is correspondingly displaced in the path of movement of the locking lug of the lock cylinder. This shift can be done by the described feature in a very simple manner by the bolt.

Furthermore, it is a feature of the present invention that the latch assembly has a control lever facing the control slope, which is slidably coupled upon actuation of the change lever with the closing cylinder distal end of the change lever, whereby the vertical movement of the change lever in the direction of open position in a horizontal movement of the latch assembly in Direction withdrawn position results. In this way, the movement of the exchange bracket can be translated directly into a return movement of the trap assembly without additional translation and with little effort.

It is also a feature of the invention that the latch assembly comprises a displaceable by a nut tractor unit, in which at least one guided over deflections in the housing pull rope is mounted, which is in operative connection with an additional lock, so by movement of the tractor unit from a starting position in a retracted position on the traction cable a case and / or a bolt of the auxiliary lock from a closed position to an open position is movable. Consequently, the trap arrangement can not only represent a simple trap in the lock housing, but also comprise a latch and / or latch mounted in an auxiliary lock. A construction with traction unit and cable offers over a conventional construction with push rods the advantage that a much lower effort is necessary. It only needs to overcome the forces of the bias of the case or the bolt of the auxiliary lock and no additional forces are expended for lifting a push rod.

As a possible embodiment of the invention, it is provided that two traction cables are connected to the tractor unit, wherein the two traction cables are led out on opposite sides of the housing and are connected to at least one additional lock. In this way, additional locks can be operated in a simple manner on both sides of the lock, which can serve as a main lock.

According to a further feature of the invention, it is provided that a slide mounted in the forend is provided, which is displaceable between a starting position and end position via a stülpseitige handle, and which blocks the traction unit in the retracted position in an end position. Such a known as "day position" setting a lock is often provided in many applications, especially in doors to public buildings or the like. In the present invention, this can also be achieved by the described feature in a simple manner for the traps and / or latches of the trap arrangement mounted outside the lock in auxiliary locks.

Finally, it is a feature of the invention that the nut has a control extension which engages in a corresponding control link of the tractor unit, wherein the control extension is kinematically coupled to the tractor in the retracted position and remains in the forward home position the traction unit in the retracted position is kinematically decoupled with the tractor unit, and that a parallel to the traction unit is provided by a spring prestressed in Stulprichtung nut slider which is kinematically coupled to the nut and by means of which the nut in the unloaded state in neutral position can be brought. Even with an activated day position of the castle, it is desired that the nut and thus the door handle located therein in a mostly horizontal neutral position returns. By the proposed feature, this can be accomplished in a very simple manner.

Weg(e) zur Ausführung der ErfindungWay (s) for carrying out the invention

The lock shown in Fig. 1 has a housing 1, which is shown for better view with the housing cover removed. Normally displaceable to the forend a latch 2 is arranged, which comprises a locking plate 5, and two, connected via a common pivot point 10 with the locking plate 5, pawl 6. The locking hooks 6 are designed as two-sided levers, the cowl-side free ends of the locking hooks 6 having mutually facing hook-shaped recesses 9. At the opposite lever arm, the locking hooks 6 guide pin 7, which are guided in scenes 8 in the housing. In the illustrated embodiment, a locking hook 6 is arranged on each side of the locking plate 5 respectively. Accordingly, the scenes 8 are associated with the guide pin 7 of the respective pawl 6 in the housing at the bottom or in the upper plate of the housing, not shown.

The bolt is actuated by a lock mechanism, which is actuated by a lock cylinder 3 via a locking lug 4. When locking the lock cylinder 3 moves it, as shown in Fig. 2, the locking lug 4 in a recess of the blocking link 34 and moves it in Stulprichtung. At the same time, the non-return lever 37 is raised against the force of a spring 39 via a control surface 40 by the locking lug 4. As a result, a locking pin 36 from a rear recess 41 of the backup lever 37, whereby the latch 2 is released. During the forward movement of the Sperrkulisse 34 this takes over a projection which engages in a recess in the locking segment 35, the blocking segment with and moves this also in the forend. A arranged on the locking plate 5 control pin 29 engages in a further recess in the locking segment 35, whereby the bolt during the forward movement of the locking segment 35 is also ejected. In the figures, only the arranged on the underside of housing housing 8 is shown, which is circular arc-shaped and when pushing out of the locking plate 5 leads to a rotation of a pawl 6 respectively. The opposite backdrop in the top plate leads to a rotation of the second pawl 6, wherein the two hook-shaped recesses 9 move towards each other.

Subsequently, the lock reaches the closed position shown in FIG. 3, in which the bolt 2 is completely pushed out and the two pawls 6 with their hook-shaped recesses 9 engage around a bolt located in the striker (not shown). In the locked position, the return lever 37 is again in its lower position by the force of the associated spring 39 and the locking pin 36 of the locking plate 5 engages in a front recess 38 of the backup lever 37, whereby the bolt is secured against reverse pressure in this position. Furthermore, the rotatably mounted actuating bow 13 of the change lever 12 was pivoted by a projection of the blocking gate 34 from the path of movement of the locking lug 4 of the lock cylinder 3.

When moving the bolt in the extended position, the locking segment 35 slides over a control slope 32 of a pusher lock 30, which is thereby raised against the force of a spring 31 and gets into the path of movement of the trap assembly. In the locked state, therefore, the trap assembly is blocked and can not be withdrawn, whereby the trap assembly serves as an additional lock.

Fig. 4 shows the lock of Fig. 1 with retracted latch 2 and on the change lever 12 retracted latch assembly. In the exemplary embodiment shown, the trapping arrangement comprises a traction unit 18 with traction cables arranged thereon and traps and / or latches (not shown) arranged in additional locks and connected to the traction cables. The tractor is biased by a spring 28 against its initial position. When the bolt 2 is retracted, a change bolt 14 arranged on the locking plate 5 presses against the pivotable actuating bow 13 of the change lever 12 and pivots it in the direction of the lock cylinder 3, so that the free end 15 of the actuating bracket projects into the movement path of the locking nose 4. When lifting the change lever 12 via the locking lug 4, the closing cylinder remote end 17 of the change lever 12 slides over a control slope 16 of the tractor unit 18, whereby it is moved against the force of its spring 28 in the retracted position. The traction cables (not shown), which are held with their ends in bearing recesses 20 in the tractor unit 18 and guided in guide grooves 21 via deflections 19 out of the housing 1, are also drawn into the housing 1, whereby the traps located in the additional locks or latch are actuated.

The traction unit 18 can also be retracted via the nut 11 via a control extension 24, which engages in a control link 25 of the tractor unit 18, as shown in Fig. 5. In the retracted position, the daytime position slider 22 can be displaced by means of the handle 23, as shown in FIG. The slider 22 is held in the activated and deactivated position by a spring-loaded catch 33. In activated day position, as shown in Fig. 7, the slider 22 blocks the tractor unit 18 in the retracted position. Thus, the nut 11 returns to neutral position, a biased by a spring 26 nut slider 27 is provided, which acts on a control extension on the nut 11 and presses it in the neutral position. The coupling between control extension 24 of the nut 11 and control link 25 of the tractor unit 18 is thus released by the nut slider 27 and the nut 11 can be moved independently of the tractor unit 18. As a particularly simple solution, with a low susceptibility to errors, the nut slider 27 is formed as a linearly moving part, which is movable in the same direction as the tractor unit 18.

8 and 9, the bolt 2 is shown in a perspective view from both sides. On each side of the locking plate 5, a respective pawl 6 is arranged with hook-shaped recesses 9 via a common pivot point 10. At the end facing away from the hook-shaped recesses 9 end of the pawl 6 guide pins 7 are provided, which engage in the respective scenes 8 in the housing 1. On the locking plate 5, the locking pin 36 are further arranged on one side, which engages in the front 38 and rear recess 41 of the backup lever 37. On the other side of the locking plate 5, the change pin 14 for displacement of the actuating arm 13 of the change lever 12 and the control pin 29, which engages in the locking segment 35, respectively.

Fig. 10 shows the change lever 12 with the pivotally mounted thereto actuating bracket 13, the free end 15 is pivotable in the path of movement of the locking lug 4. The closing cylinder remote end 17 of the change lever 12 is slidably coupled to the tractor unit 18 via the control slope 16.

In Fig. 11, the nut 11 is shown, which has a recess for a square of a handle, such as a doorknob. Furthermore, the nut has a control extension 24, with which it engages in a control link 25 of the tractor unit 18. Further, an attack surface 42, designed here for example as a shoulder, for the control extension 43 of the nut slider 27 is provided. The nut slider 27, which is shown in FIG. 12, has, in addition to the control extension 43, a receptacle 44 for the spring 26.

FIGS. 13 and 14 respectively show perspective views of the tractor unit 18 from both sides. On one side of the traction unit 18, two bearing recesses 20 are provided for the suspension of traction cables. On the other side is the control slope 16, which is coupled to the change lever 12, the control link 25 for the control extension 24 of the nut 11 and a receptacle 45 for the spring 28 of the tractor unit 18th

In Fig. 15, a possible embodiment of a pusher lock 30 is shown, which is pushed over a control slope 32 during ejection of the bolt 2 in the path of movement of the tractor unit 18 and thus blocked against retraction. The pusher lock 30 can be guided in a simple manner by a guide web 46 in a corresponding groove in the housing.

Fig. 16 shows the slider 22 for the day position. The slider projects with a handle 23 from the forend and is thus displaceable between activated and deactivated position. Thus, the slider 22 is held securely in two positions, a spring-loaded detent 33 is provided, which engages in corresponding recesses in the housing.

In Fig. 17, the return lever 37 is shown. The return lever is lifted by the control surface 40 of the locking lug 4 when locking and unlocking against the force of a spring, whereby the locking pin 36 of the locking plate 5 from the front 38 to the rear recess 41 and vice versa is movable.

FIG. 18 shows the blocking segment 35, which is pivotably mounted around the lock cylinder 3. The control pin 29 of the locking plate 5 is guided in the recess 47 of the locking segment 35. In a further recess 48, the blocking gate 34 shown in FIG. 19 is guided. This has a recess 49 for the locking lug 4 and is linearly displaceable by this in the direction of movement of the bolt. At the front end, a projection 50 is arranged, which serves for the displacement of the actuating bracket 13.
