Description

The invention relates to a lock having a rotatably mounted rotary member, a linearly displaceable sliding element and a transmission device. The transmission device is connected to the rotary element and to the sliding element.

From document EP 2 264 265 B1 a lock with a lock housing and a rotatably mounted in the lock housing lock nut is known. The lock nut is in this case geared connected to a linearly displaceable mounted in the lock housing drawbar. For this purpose, a suspension eye is formed on the pull rod, which engages on a radially projecting hook of the lock nut. A rotation of the lock nut causes a linear displacement of the drawbar. The pull rod is connected to a compression spring, which acts as a return spring for the lock nut.

The lock 1 according to the invention is in the Figures 1 and 2 shown. The lock 1 has a lock housing 1a, in which a lock mechanism is mounted. The lock mechanism comprises a latch 2, a lock bolt 3, a lock nut 4 and a gear slide 5, which are movably mounted in the lock housing 1 a, further, the lock 1 has a receptacle for a lock cylinder.

The lock nut 4 is provided with a receiving opening for receiving a mandrel of an actuating handle. The actuating handle is not shown in the figures. Upon actuation of the actuating handle, the lock nut 4 from the position in FIG. 1 counterclockwise by an angle of about 30 ° in the position in Fig. 2 turned. The lock nut 4 is in this case connected via the gear slide 5 with the latch bolt 2 and the lock bolt 3 geared.

The lock nut 4 is connected to a return spring device 6, which locks the lock nut 4 after the end of the actuation from the actuated position in FIG Fig. 2 into the unconfirmed basic position in Fig. 1 resets.

The lock nut 4 is designed as a multi-part nut, see Fig. 1b . 1c . 2 B . 2c , The lock nut 4 comprises in the illustrated embodiment, a rotatable outer Nussteil 4a, a rotatable inner Nussteil 4i and a Intermediate middle nut part 4m. The outer Nussteil 4a and the inner Nussteil 4i each have a receiving opening 4aa, 4ia for the positive insertion of a dome of an actuating handle. The actuating handles with the mandrel are not shown in the figures. The center nut 4m has a passage portion 4d formed coaxially with the receiving opening 4aa of the outer nut part 4a and the receiving opening 4ia of the inner nut part 4i. In the passage area 4d of the middle part 4m, a partition member 7 is arranged, which blocks the passage area for the passage of a dome of the actuating handle. The center nut part 4m interacts with the gear slide 5 of the lock mechanism.

The lock 1 shown in the figures is designed as a so-called panic lock. In the panic lock, the inner Nussteil 4i is permanently coupled with the Mittennussteil 4m mechanically. Upon actuation of the operating handle connected to the inner Nussteil 4i the lock 1 can be unlocked manually at any time. In this case, upon actuation of the operating handle connected to the inner Nussteil 4i the lock bolt 3 is pulled into the lock housing 1 a and repealed the blocking of the lock latch 2 against retraction into the lock housing 1a. The lock 1 is then unlocked. This unlocked position of the lock with retracted lock bolt 3 is in FIG. 1b shown.

The outer Nussteil 4a and the inner Nussteil 4i are connected to a return spring means 6, namely the outer Nussteil 4a with a return spring 6a and the inner Nussteil 4i with a return spring 6i. The return spring 6a and the return spring 6i are designed as helical springs which form the associated slider designed as a pull rod surrounded coaxially. They are each supported at one end on the lock housing 1a on a housing-fixed bearing and supported with its other end to the slider designed as a pull. Like from the Figures 1b and 2b recognizable, the return spring 6a is supported on a slider 8a and the return spring 6i on a slide 8i. The slide 8a is guided linearly displaceable in a sliding bearing 80a and the slide 8i in a sliding bearing 80i.

Trained as a pull rod slide 8a is connected to the outer Nussteil 4a via a connecting rod 9a. Trained as a pull rod slide 8i is connected to the inner Nussteil 4i via a connecting rod 9i. The connecting rod 9a, 9i is in each case designed as a rigid link, which is articulated with its one end at the free end of the slide 8a, 8i and with its other end eccentrically on the outer Nussteil 4a and on the inner Nussteil 4i. As articulation, a pin is provided in each case, which engages in an eye in the manner of a pivot bearing. For this purpose, at the free end of the slide 8a, 8i, a transverse pin is formed and at the associated free end of the connecting rod 9a, 9i a complementary eye. At the other end of the link, an eye is also formed in each case, which is pivotally mounted on a pin arranged eccentrically on the outer Nussteil 4a and the inner Nussteil 4i.

The connecting rod 9a, 9i is in this case formed as an arcuately curved body, as in the FIGS. 1a and 2a can be seen. The design of the connecting rod 9a, 9i as an arcuately curved body has the advantage that it is avoided that the connecting rod 9a, 9i passes during the rotation of the nut part 4a, 4i in the region of the receiving opening of the nut part 4a, 4i, thereby covering the receiving opening , This results in a collision of the connecting rod 9a, 9i excluded with the mandrel an attached to the receiving opening of the nut part actuating handle. The curvature of the connecting rod 9a, 9i is in this case chosen so that in the entire rotational range of the nut part 4a, 4i from the basic position to the end position of the rotation, the receiving opening is released and the connecting rod 9a, 9i does not cover the receiving opening of the nut part 4a, 4i.

The inner Nussteil 4i is firmly connected via a coupling screw with the central nut 4m, so that upon rotation of the inner Nußil 4i the central nut 4m is also rotated. The connecting rod 9a, 9i has at the apex of its arcuate curvature on a recess portion in the region of the coupling screw during the rotation of the nut part 4a, 4i passes. This situation, in which the coupling screw enters the recess area of the connecting rod 9a, 9i, is in the FIGS. 2a and 2 B shown. The curvature of the connecting rod 9a, 9i is thus dimensioned such that the coupling screw does not come into collision with the connecting rod 9a, 9i in the entire rotational range of the nut part 4i.

As already described above, an eye is formed at one end of the connecting rod 9a, 9i, which is mounted pivotably on a pin arranged eccentrically on the outer nut part 4a or the inner nut part 4i. As regards the arrangement of the pin on the nut part 4a, 4i, it is essential that upon rotation of the nut part 4a, 4i, starting from its basic position, the pin moves away from the return spring 6a, 6i and the sliders 8a, 8i on its circular path of movement Passing through a section of a circle. This arrangement of the pin on the Nussteil 4a, 4i allows a space-saving design of the castle.

Trained as tie rods slide 8a, 8i are arranged together with their associated coil springs 6a, 6i in a supported in the lock housing storage rack. The storage rack comprises a bearing plate 80p in which a linear slot is formed, in which the slider 8a and 8i is linearly guided by engagement of a follower arranged on the slider 8a, 8i. The slides 8a, 8i are arranged on opposite sides of the bearing plate 80p. The bearing plate 80p further comprises a transverse plate 80q in which a guide hole is formed for additional guidance of the slider 8a, 8i.

Fig. 1 shows the lock 1 according to the invention in the basic position with unconfirmed handle. As already mentioned above, the handle is not shown in the figures. The operation of the handle causes a rotation of the coupled with the handle nut part 4a and 4b in a clockwise direction. As a result of this rotation of the nut part 4a, 4i, the pin arranged eccentrically on the nut part 4a, 4i is moved, as a result of which the connecting rod 9a, 9i connected to the pin is displaced. The displacement of the connecting rod causes a linear movement 9a, 9i of the pull rod designed as a puller in the illustration in the figures down, whereby the coil spring is compressed. As soon as the nut part 4a, 4i impinges on the bearing plate, the in Fig. 2 reached position shown.

If now, starting from the in Fig. 2 shown position, the actuating handle is released, the coil spring for resetting the nut part 4a, 4a is released. The provision is made by relaxing the coil spring. In this case, the coil spring presses the associated pull rod 8a, 8i in the illustration in the figures when relaxing up, wherein also connected to the coil spring connecting rod 9a, 9i is relocated. The displacement of the connecting rod 9a, 9i causes a rotation of the associated nut part 4a, 4i in the counterclockwise direction in the sense of a provision. As soon as the pull rod 9a, 9i has reached its end position, the lock 1 is again in the in Fig. 2 illustrated basic position.
