Description

The invention relates to a door handle set, in particular for vehicle doors, with one of the handles supporting square shaft and a nut arranged on this shaft, which triggers the door lock Joint piece acts.

From the patent specification GB 2 27 112 is a door locking device has become known for vehicle doors in which a square shaft has an eccentric disk actuated, which actuates a claw bolt via a ring and a connecting link. The movement of the on the The eccentric sliding ring is limited by a stop on which the ring has a flattened surface runs up. The eccentric sets a door handle rotation in a pivoting movement via the connecting link of the claw bar.

Door handle sets have the task of operating a linkage that unlocks the door so that they are mechanical is to be opened, and actuates a switch that switches an auxiliary drive. In certain operating states it is necessary that any doors can be locked, so that the function of the door handle set will be annulled.

A cancellation of the function is not provided in the known locking device.

There is a risk of mechanical blocking of the handles would bring about their violent damage, one breaks the functional chain, so that one can operate the door handles without this having any effect.

The invention has for its object to be a particularly To create a simple handle set consisting of a few parts that does not require any additional space is required and that by means of a special key from a or can be locked from both sides

This object is achieved according to the invention in that the joint piece on an eccentric in such a way is adjustably mounted that the nut in a latching position of the eccentric is frictionally engaged on the joint rests, while in the other locking position it remains out of engagement with the joint piece

An embodiment of the invention is explained with reference to FIGS. 1-4 of the drawing. It shows
F i g. 1 a door handle set from the front,

F i g. 2 this set from the side,
F i g. 3 a view from above,
F i g. 4 a section

Corresponding parts are provided with the same reference symbols.

In Fig. 1 is denoted by 1 of a handle plate on which all other parts are functional. In A square shaft 2, which carries a nut 3, is mounted on the handle plate. A second wave 4 that is on both Ends with triangular actuating pins 5 is equipped, has an eccentric 6 in which a joint piece 7 is mounted On the square shaft 2 sits a handle 8, which via the nut 3 on a compression spring 9 and the Joint piece 7 acts. The movement of the nut 3 is limited in both directions by a pin 10. Of the In the illustration, the eccentric 6 is in the end position in which the joint piece 7 is in contact with the nut 3. So if the handle 8 is moved clockwise, the joint piece 7 rotates counterclockwise, so that the door can be unlocked via a linkage (not shown).

If the shaft 4 is rotated 180 ° so that the eccentric 6 assumes the other extreme position, the short lever arm Ta of the joint 7 is out of engagement with the nut 3. The handle 8 can therefore be operated as desired without the joint 7 moves and the door is triggered. The arms of the joint piece 7 form an angle <90 °.

The eccentric shaft 4, 6 has two locking positions. In both positions, the eccentric 4 lies on the bisector of the joint 7 which coincides with the cutting plane BB and which at the same time corresponds to the resultant of the forces occurring. This means that the joint piece 7 does not load the latching device of the shaft 4.

The bearing bore of the joint piece 7 is open in the direction of the bisector, so that the joint piece 7 can be mounted on the eccentric shaft 4, 6 at any time without changes. The force resultant holds that Joint piece 7 firmly in its storage.

FIG. 2 shows a section along the line AA in FIG. 1. The complete door handle set can be seen from the side. The handle plates 1 and 11 are connected to one another by screws 12, 13. The handles 8, 14 are attached to the square shaft 2 by means of two-hole screws 15, 16. One can clearly see the eccentric 6 on the shaft 4 and the triangular mandrels 5 and 17. The design of the joint piece 7 has the great advantage that the shaft 4 and the eccentric 6 are made from one piece.

let the assembly time be very short.

; t the arrangement from above. Between the 1, 11 with the two-hole screws 15, 16 3 and the joint piece 7.
It is a section along the line BB in FIG. 5 ie shows above all the locking device, the screw 18, a spring 19 and a ball ie the ball engages alternatively in bores 4 a in the shaft 4.

Claims (5)

Patent claims: 1. Door handle set, especially for vehicle doors, with a square shaft supporting the handles and a nut arranged on this shaft which acts on a joint piece that triggers the door lock acts, characterized in that the joint piece (7) on an eccentric (6) in such a way is adjustably mounted that the nut (3) in a locking position of the eccentric (6) frictionally on the Joint piece (7) rests, while in the other locking position it is out of engagement with the joint piece (7) remain. 2. Door handle set according to claim 1, characterized in that the joint piece (7) is angled at its bearing point and that the bearing bracket is open in the direction of the bisecting line coinciding with the cutting plane (BB) , so that the joint piece (7) without changes on the Eccentric shaft (4,6) can be mounted. 3. Door handle set according to claim 1, characterized in that the nut (3) one on the joint piece (7) attacking nose, a second nose connected to a return spring (9) and a sector-shaped one Has cutout, which in connection with a fixed bolt (10) as a two-sided stop works. 4. Door handle set according to claim 1, characterized in that the two shafts (4, 2), the nut (3) the joint piece (7), the spring (9) and the stop bolt (10) on the one handle plate (1) are functional are mounted and a second handle plate (11) only carries the counter bearing. 5. Door handle set according to claim 1 and 2, characterized in that the upper and lower Dead center of the eccentric (6) lies on the bisector of the joint piece (7), so that the built-in Latching device (18,19,20) is not loaded by the resulting forces on the joint piece (7).
