Abstract

The invention relates to a device for operating locks (16) on doors or hatches of vehicles. A fixed support (10) is arranged on the door. A moving unit (20) is mounted (11, 12), such as to pivot on the support (10), belonging to which is at least one handle (21). Spring loading (25, 26) ensures the unoperated moving unit (20) is held in a flat rest position on the support (10). On operating the handle, the moving unit (20) must be pivoted against said spring loading, whereby the lock (16) is operated. A damping unit (30) ensures that the returning moving unit (20) pivoting action is decelerated. According to the invention, a reliable, economical damping unit (30) is obtained, whereby an elastic body (31) is arranged in at least one position on the moving unit (20) which extends outwards with a projection (32). On the return movement (39) into the rest position the extending projection (32) is deformed against a fixed counter-surface (40), whereupon the movement energy is largely dissipated. On reaching the rest position, the deformed projection (32) is supported against the counter-surface (40).

Description

Device for actuating locks on doors or flaps of vehicles

The invention is directed to a device specified in the preamble of claim 1. The damping device has the task to slow the return movement of the movement unit and thereby dampen the impact noise when the actuated movement unit of the device is released and due to their spring load back into their Resting area returns.

In the known device of this type, a piston-cylinder device is used as damping device, which manages as a cylinder filling with the ambient air, (DE 100 30 331 Al). One end of this device is mitbeweglich with the handle and the other connected to the carrier. Although this damping device has proven itself, but is costly and space consuming.

It is known in other types of devices to provide rubber pads on the stationary outer lining of the door or flap, against which the handle abuts after its operation. However, this rubber liner does not slow down the return pivoting movement, but serves as a paint protection for the outer lining and for sealing purposes.

The invention has for its object to develop a reliable and inexpensive device referred to in the preamble of claim 1 species, which is designed to save space. This is inventively achieved by the measures mentioned in claim 1, which has the following special significance.

The elastomeric element according to the invention is a component of the movement unit and is therefore also moved when the handle is actuated. On the support a stationary counter surface is provided, on which the free piece of the elastomeric member already deformed during the return movement of the movement unit and thereby converts the kinetic energy into deformation work. In the rest position, the free piece on the counterface has been maximally deformed. ,

It is particularly advantageous to form the elastomeric member as a bending beam, which is bent by the counter surface when the moving unit of their Resting position is approaching. The rebound energy to be damped is then consumed in the bending work of the bending beam. By a sufficient beam length and a suitable position of the counter surface, the buckling begins sufficiently early to use up the excess energy to the rest position of the moving unit.

It is advisable to arrange the bending beam in the region of a self-contained in the carrier bell crank, acts on the actuated handle and then forwards the handle movement to the lock.

Further measures and advantages of the invention will become apparent from the dependent claims, the following description and the drawings. In the drawing, the invention is shown in two embodiments. Show it:

Fig. 4, the same device in its working position.

In the diagram of Fig. 1 and Fig. 2, the components of the device according to the invention are indicated only schematically. These include first in the interior of a vehicle door to be fastened carrier 10, which rests after its attachment and is mostly hidden by a dash-dotted line indicated outside door trim. This carrier has at least two pivot bearings 11, 12 for two parts 21, 22 a movable assembly 20, which will be referred to below as "movement unit." This movement unit consists of a handle 21 arranged substantially on the outside of the door 13 in front of the panel 15 and a reversing lever 22 arranged in the door interior 14.

The handle 21 can be mounted from the outside of the door 13. For this purpose, the handle 21 has at one end 23 bearing points, which are accommodated in the one pivot bearing 1 1 of the carrier 10. The other end of the handle 24 has a boom

24, which has the task of cooperating with handle 22 with the lever. The handle 21 is under the action of a spring load 25, the spring members are not shown in detail. This spring load 25 may also be elsewhere, e.g. be generated in the region of the reversing lever 22. The spring load 25 strives to keep the handle 21 in its rest position indicated by the auxiliary line 21.1 in FIG.

Also on the bell crank 22 acts in Fig. 1 by a force arrow 26 illustrated spring load, the cause of which, as I said, may be the same as the spring load 25 of the handle 21. The bell crank 22 is on the already mentioned second pivot bearing 12 from Carrier 10 pivoted. The spring load 26 strives to keep the lever in the apparent from Fig. 1, illustrated by an auxiliary line 22.1 rest position. The rest position may be determined by stop means, which are not shown.

The reversing lever 22 is divided into several arms. There is a first arm 27 with an engagement point 19 for the described boom 24 of the handle. Then there is another arm 29, which has a point of attack for a schematically illustrated in Fig. 2 by an arrow 18 connection to a lock 16, not shown. Finally, the reversing lever 22 still has a in Fig. 1 and 2 marked 17 counterweight, which acts as a third lever arm.

In Fig. 2, the handle is against the effects of the two mentioned spring loads

25, 26 has been manually operated and is in its marked by the auxiliary line 21.2 working position. Because of the coupling between the boom 24 and the engagement point 28 is not only the handle 21 about its pivot bearing 11, but at the same time the lever with respect to the pivot bearing 12 has been pivoted. In Fig. 2, the reversing lever 22 is in its marked by the auxiliary line 22.2 working position.

When the handle 21 actuated in FIG. 2 is released, the spring loads 25, 26 ensure that both components 21, 22 of the movement unit 20 are pivoted back into their rest position 21.1 or rest position 22.1 of FIG. Because the springs in Fig. 2 are even further tensioned with respect to Fig. 1, the moving unit 20 would rebound with great force and thereby cause a very unpleasant impact noise. The rebound can also damage paint or the components involved.

To exclude this, the invention proposes a damping device 30, which is inexpensive and only takes up little space to complete. For this it is sufficient to connect an elastomeric member 31 on the one hand firmly with one of the components 21, 22, of which it protrudes at the other end with a free piece 32 for deformation purposes. This deformation is caused by mating surfaces 40, which are the resting part of the carrier 10. In the present case, the damping device 30 is formed in the following, as best seen in FIG. 2 manner.

As the elastomeric member, a bending beam 31 is used, which sits in the present case on the lever. For this purpose, the previously mentioned ballast arm 28 formed by the counterweight 17 is used. For this purpose, two lateral projections 35 are provided on the counterweight 17, which enclose a slot 36 between them. In this slot 36 is serving for beam attachment inner mounting piece 33, which ends with a beam head 34. The beam head 34 protrudes out of the slot 36 and bears against a contact surface of the two projections 35. After its assembly according to FIG. 2, the bending beam 31 protrudes with a free beam piece 32 according to FIG.

The belonging to the damping device 30 according to the invention mating surface 40 is angled in an L-shape, as shown in FIG. 2. The L counter surface 40 consists of a seated on the carrier 10 stop leg 41 and an angled extending bending leg 42. The damping device 30 is effective when after its manual actuation of the handle 21 is released and due to its Spring load 25 or 26 is moved back to its rest position 21.1 or rest position 22.1 along the dash-dotted lines in Fig. 2 illustrated return route. The result can be seen in FIG.

On the way back 39 first encounters the bending beam 21 with its free end of the beam 37 against the upper edge of the bending leg 42, whereby a bending operation in the free beam piece 32 is initiated. By this deformation of the bending beam 31, the kinetic energy of the jointly retrograde moving parts 21, 22 of the moving unit 20 is consumed. The bending beam 31 is bent over around the outer projection 35 around, whereby in the final phase of the deformation, a kink crest 38 is formed. In the rest position 22.1 comes the Knickscheitel 38 for support on the aforementioned stop leg 41 of this L-shaped counter surface 40th

The length of the projecting beam piece 32 from the bending beam 31 is coordinated with the position of the L-shaped mating surface 40 such that upon reaching the rest position, the kinetic energy of the unit 21, 22 is substantially used up. The return movement 39 is thus slowed down so much that upon reaching the rest position 22.1, the movement of the unit 21, 22 is largely completed. The bending beam 31 touches with a Knickscheitel 38 the stop leg 41 very gently. The impact sound is virtually eliminated. The cooperating with the L-shaped counter surface 40 bar piece 32 surrounds the abutting end of the ballast arm 28 in the region of the projection 35. The Ballastarmende is "wrapped" by the bending beam.

The concrete embodiment of the device according to the invention is, as already mentioned, illustrated in FIGS. 3 and 4. Dash-dotted the position of the pivot bearing axis 12 is shown by the lever 22. A leg spring 43 is placed around the axis 12, which generates the two spring loads 25, 26 explained in connection with FIGS. 1 and 2. In the carrier of Fig. 3 and 4, but a handle is not mounted. Therefore, one sees a free passage 44 at that location of the carrier 10 where the aforementioned boom 24 of the handle of Figs. 1 and 2 comes to rest. Such a boom 24 would cooperate with the visible in Fig. 3 attack surface 19 of the actuating arm 27. As far as the previous ones Reference signs are registered, the previous description applies. It is sufficient only to the further, not yet explained details to enter.

On the carrier, a shell part 45 is formed, the shell interior forms the above-described L-shaped counter surface. Thus, the tray bottom recognizable in FIG. 4 fulfills the task of the described stop leg 41, while the outer tray edge acts as a bending leg 42. The side wall is provided with a cutout 46, which is adapted to the rectangular profile of the bending beam 31. In this section 46 comes in the deformation case, as shown in FIG. 3, the bent free beam end 37 to lie.

If the deformation work of the bending beam 31 to exhaust the return energy should not be sufficient, one can increase the length of the projecting beam piece 32 and provide the mating surface 40 with numerous part walls, which lead to a multiple buckling. It is also possible by means of a suitable beam profile in the direction of the beam length to ensure that the right amount of kinetic energy is used up in each phase of the return movement 39.

Finally, it would be conceivable to use the elastomer member or the bending beam 31 also at a moderate stop position of the movement unit 20 in the working position 21.2 or working position 28.2. For this purpose, it is sufficient to arrange a suitable, not shown in detail, counter surface on the support on which the elastomeric member or the bending beam comes to rest.
