Abstract

A cable pull for an air flap or the like in a motor car or similar vehicle comprises a stranded steel cable (1), which is hammered down from a larger diameter to a smaller diameter and in this manner provided with a smooth surface all round. The cable (1) is guided in a plastics material tube (2), which forms a casing of the pull. <IMAGE>

Description

SPECIFICATION Cable pull The present invention relates to a cable pull, especially an actuating pull for an air flap or the like in a motor car or similar vehicle.
It is known to actuate air flaps of that kind and similar smaller components by means of Bowden pulls. However, due to the friction of the stranded steel cable in the guide casing, relatively close limits have been set on the length and arrangement of such Bowden pulls.
The pulls had to be relatively short and they could not, or not readily, be disposed in an arc. Moreover, they operated only in tension, often against a spring force for the return of the pull. There is thus a need for a pull which has less friction and can be disposed in an arc over longer distances.
According to the present invention there is provided a cable pull comprising a plastics material tubular casing, and a stranded steel cable which is guided in the casing and which is hammered down from a larger diameter to a smaller diameter thereby to provide a smooth circumferential surface.
By means of reducing a stranded steel cable in diameter through hammering and in this manner providing it with a smooth surface all around, and guiding this smooth stranded cable in a synthetic material casing, friction is quite substantially reduced and the pull can be arranged very much more easily in an arc. In other words, even in the case of arrangement in one or more arcs, the pull remains actuable easily by reason of the lower friction. Moreover, the stranded cable is stiffened to such an extend that the pull operates in both tension and compression. The combination of a standard cable smoothed through hammering with a plastic material guide casing, in particular in the context of actuation of smaller components, affords unexpected technical advantages.
An embodiment of the present invention will now be more particularly described by way of example with reference to the accompanying drawings, in which: Figure 1 is a crossed section of a hammerdown stranded cable for a cable pull embodying the invention and Figure 2 is a schematic partly sectional view of the pull.
Referring now to the drawings, there is shown in Fig. 1 the cross-section of a sevencore stranded cable which has been hammered down from a larger diameter to the shown diameter and in that case compacted.
The resulting all-round smooth surface of the cable is easily recogniable in Fig. 1.
As Fig. 2 shows, the smooth stranded cable 1 is guided in a flexible plastic material tube 2, which is shown arranged in an arc.
Eyelets la are fastened to the stranded cable 1 and fittings 2a are mounted at the tube 2, and serve for the connection of the cable to the actuating elements and fixing of the tube 2 to walls or the like. The tube 2 can consist of several layers of plastics material of different kinds.
1. A cable pull comprising a plastics material tubular casing, and a standed steel cable which is guided in the casing and which is hammered down from a larger diameter to a smaller diameter thereby to provide a smooth circumferential surface.
2. A cable pull as claimed in claim 1, wherein the casing comprises a plurality of layers of different kinds of plastics material.
3. A cable pull substantially as hereinbefore described with reference to the accompanying drawings.
4. A cable pull as claimed in any one of the preceding claims, the pull being adapted for actuation of a vehicle air flap.
