Abstract

PURPOSE:To provide a guide member with sufficient endurance against the force acting axially and turning force about the axis by firmly sticking a sleeve and a working cable to each other. CONSTITUTION:A working cable 1 provided with a core 3 which is made up by sequentially bundling associated independent steel wires or steel fibers, and said core 3 is provided with a spiral coil 4, made of a single relatively thick wire. The spiral coil is wound around the core with equal intervals thereon. One end of the wire of the coil 4 is connected to the core 3 in form of seal. The firm connection of the core 3 to the wire of the coil 4 is ensured by the end seal 5 which is mechanically wedged. The end seal 5 also functions as a fixing point for the locking and fitting of a roke into which the guide member is inserted. A part 6 of the core 3 freeing from the coil 4 thereon and having a free length is engaged into a sleeve 7 which is molded integrally with the main body 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for forming a connection between a guide body and an actuation cable that resists axial and/or rotational loads, as well as The present invention relates to a guide member for a movable opening/closing part of a vehicle, and a method for producing the same.

In the case of such a type of guide element for an assembled opening/closing movable part, the actuating cable must be connected to the guide body without any play. Such members are particularly described in, for example, U.S. Pat. No. 4,056.27.
No. 4, U.S. Patent No. 9084926 and British Patent Jl.
No. 1,184,246 is used in the known wind lifter and sliding roof of automobiles. While the guide body is generally formed of planar material.

The actuation cable has a core that is preferably a plurality of strands of polyamide hair.

A helical coil formed of a single relatively thick and stiff wire is wound onto the core with uniform spacing between adjacent turns of wire.

At the end of the actuation cable, a length of the core is free of wire coils and is rigidly connected to the guide body. A drive pinion engages the void between the windings of the wire. The pinion is rotated by one, for example a sliding roof crank, or a motor, especially an electric motor. The pinion is guided in the cavity between the windings of the wire, as in a screw or spindle. The actuation cable of the assembly guide device is moved in the axial direction by the rotation of the pinion,
As a result, a guide body, which is attached, for example, to the frame of a sliding roof or a windshield, is pulled or pushed. Therefore, the connection between the core of the actuation cable and the guide body must be subjected to the tensile and compressive axial forces required for the movement of the sliding roof or windshield.

However, in addition to the axial force, the rotation of the pinion transmits a tangential force to the actuating cable, which likewise acts between the core of one actuating cable and the guide body. Therefore, such a connection must be able to withstand this dual axial and radial load.

Movement of a sliding roof generally requires a pair of parallel guide members in which tension or compression is simultaneously applied to the sliding roof.

In order to avoid tilting of the sliding roof, the guide element must be manufactured in such a way as to ensure high dimensional accuracy and small tolerances for the connection between the core of the actuating cable and the guide body.

However, hitherto such manufacturing has been extremely difficult and conventional connections have been unsatisfactory, particularly when subjected to radial torques.

According to the prior art, the aforementioned connection is made by inserting the cylindrical sleeve of the guide body into the core of one actuating cable and providing a seal at the protruding end of the core. This seal is approximately eight cod long and is mechanically wedged to the core of the actuating cable and serves as a joint subject to the tensile forces acting on the cable. Although the fixation of the end seal to the core will often result in a certain amount of axial play between the actuating cable and the sleeve, the dimensional accuracy required for the connection must be met mechanically and You can receive tensile deer.

However, the use of such an end vole is not sufficient to prevent rotational movement about the axis of the actuation cable within the sleeve of the guide body.

So far to counteract the radial torque.

In addition to providing end seals, the ends of one actuation cable were glued into the sleeve to make the connection sufficiently rigid to receive the transmitted tangential forces.

In view of the fact that the adhesive surfaces are subjected to continuous mechanical alternating loads, special adhesives of high quality and cost, such as cyan adhesives, must be used. Furthermore, surface preparation and very careful handling are required to obtain a proper connection. however.

Even the best adhesive connections may come loose.

Finally, a precisely controlled multi-step operation can be achieved by double fastening with different connecting media, namely adhesives, seals and K.

An important object of the present invention is to receive a high load between the core of the actuating cable and the thick body of the Buchstick guide.
Provided is a guide member for a movable opening/closing part of a vehicle's shaft provided with a connection that resists axial and/or rotational loads such as tension when tension, compression, and rotational forces act on the core. It is to be. Dimensional tolerances must be minimal. Furthermore, the aim is to provide a method for producing such a component. The method additionally saves materials and can be carried out even in a single operation. j! ! 10 Partial objects are achieved by means of a guide member in which the core of the actuating cable resists axial and/or axially rotational loads, such as tension, and the guide body is fixed to the sleeve by welding.

How to achieve the connection between the branutics guide body and the wires in one operating cable core.

It is characterized in that the two members are connected to each other by ultrasonic bonding. According to a particularly advantageous embodiment of the method:
The guide body is ultrasonically bonded to the actuating cable core and at the same time mechanically pressed against the core. The method of the invention provides a secure connection that is axially and laterally pressurized to an extent that is superior to previous guide members. This method does not require expensive adhesives and possibly additionally saves on the previously required edge seals. An absolutely rigid connection is obtained between the actuation cable and the guide body, which resists all thrust, tensile and radial forces between the actuation cable and the guide body.

Further, the invention will be explained with reference to two embodiments shown in the drawings. FIG. 1 is a side view of a guide member connected to a movable opening/closing part such as a sliding roof of a window for a vehicle such as a vehicle, that is, a sliding glass that opens and closes the window by sliding, and the guide member is regulated according to the present invention.
