Flexible pull and push cable

The! Firing betefft a displaceably guided in a pipe or hose means arranged in ball cages balls _s "flexible pull and push cable" Such cables are known, cf. "zobo British Patent Specification 336 347 and the US Patent 1,930,272 ο

For cables of the type mentioned, the problem is to make the rolling in your hose or pipe balls in the ball cage AUOH relative to the cable itself limited rollable _s lim, in particular with a curved installation, to facilitate the operation ^ to the other, the ball cages not all of them are collected in one place, as proper guidance is then not guaranteed at the places free of Eugel cages »The known pull and push cables do not meet this requirement! at a certain place, then there is a relative movement between cables

and ball not given ^ or the Eugel cages can move axially arranged on the cable, then there is a risk of that collect the cages in one place »

The hiring is based on the task, the two seemingly each other to realize contradicting! demands = according to! inflation the object is achieved in that the ball cage is fixedly arranged on the cable and several distributed on the circumference Has axial slots in which the balls are slidably arranged sind5 or in that the ball cages are axially displaceable are arranged on the cable and that between two ball cages a limit stop is provided in each case »in both Sufficient relative movement is ensured between the cable and the balls, which is in the length of the slots or in the position of the attacks finds its limit »

The German patent specification 610 080 describes a pull and push cable became known in which the balls are not in a ball cage are arranged, rather freely in the spaces between adjacent cores of one consisting of several cores Cables are routed = here, too, there is a risk that all the balls will collect in one place ! Price increases will be transferred this ball guide to ball cages of limit stops having cables »

Detailed examples of the inflation are shown in the drawing. and are described in more detail below »It shows =

! ig- 1 a section through a pipe with a piece of cable j Pig. 2 shows a cross section through a ball holder in strong

enlarged scale $
3 shows a longitudinal section through a cable in a modified embodiment;

3? Igo 4 a cross section through a ball cage and ü'igo 5 the top view of a ball cage with in the longitudinal direction cut pipe in a modified embodiment.

In the embodiment according to 3? Ig. 1 and 2 a flexible pull and push cable 1 is used, which through a pipe or through a hose 2 is guided. This hose 2 can be made of plastic, for example, so that it bends easily can be relocated =

At a certain distance 1 ball holders 3 are arranged on the cable, according to Pig. 2 z "B" with four wedge-shaped in cross section Butes 4 are equipped »A ball 5 is inserted into each groove, which rests with two points on the planks of the groove 4, while with a third point the inner surface of the pipe or hose 2 touches »In order to hold the balls in the ball holder, a sleeve 6 is pushed on with the corresponding Slits 7 are provided for the passage of the balls.

Such a pull-and-push cable is simple in construction because the Cable can be formed from simple wires by the fact that

between the cable and the inner surface of the hose 2 balls available? there is a strong reduction in friction, of the cable in the hose »Because the balls with two points rest on the ball holder 3, when the cable is actuated, the balls move by half the way of the Ball holder 3 °

In the illustrative example according to Pig. 3 to 5, a cable 8 is used, which consists, for example, of a core wire 8a and six outer cores 8b. A ball cage 9 _S is used here, which in the exemplary embodiment shown holds six balls 5. Each of these balls runs in the space between two cable cores 8b and rests against the inner surface of the tube or hose 2 at a further point. In this embodiment, the ball cage 9 rotates with the balls 5 when the cable is axially displaced. If, however, the cable should be rotated at the same time during this axial displacement, the ball cage 9 remains in its radial position and is only displaced axially. In Pig. 3 is also indicated that lie between the individual that the ball cage 9 can perform, Eegrensungsanlagen 10 are arranged on the cable 8, so that, especially during assembly, the ball cages 9 are arranged at a certain distance. These stops can consist, for example, of Metallhüls.en which are clamped onto the cable 8.

In Pig. 5 it is finally indicated that the spherical

cage 9a can also embed in the tube 2 to reduce the axial displacement of the ball cage to avoid »With this version, of course, the cable S must be in a longitudinal displacement can also rotate as the balls 5 in this 3? all have to slide through the spiral grooves between two cable cores 8b »
