Abstract

A guide body for mechanically-flexible remote controls for guiding a pulling body, in particular a cable pull (4), is described. By a modular construction of the individual mutually movable members (2, 3) a guide body is given, which is easy to configure, has a low weight and allows easy installation.

Description

The The invention relates to a guide body for mechanically-flexible remote operations to the leadership a pulling body, in particular a cable, with a modular structure of individual against each other movable members, by means of a locking or Snap connection detachable with each other are connected, wherein each member has a latching head and a latching pan having.

such remote controls for the transmission of Tensile and / or compressive forces find, for example, in the automotive industry in many ways Application, such as fuel cap unlocking, throttle cable, switching and Wählzug, Belt tensioners and the like.

mechanical Control cables for transmission of tensile and / or compressive forces consist in principle of two functional components, the outer flexible one Guide body and the flexible tensile body, the free in the guide body is slidably mounted. The guide body consists in simplest case of an ordinary Coil spring or a hose, the flexible tensile body a wire. Regarding the management body there it varied Embodiments, For example, as a round wire spiral with or without plastic inner tube, as plastic coated round wire spiral, flat wire spiral and the like

adversely in the known guide bodies, that she to the respective length the later control cable have to be coordinated. If the guide body once cut is, is an afterthought renewal not possible anymore. Other disadvantages are the relatively high weight and sometimes elaborate manufacturing process.

From the post-published DE 100 23 670 A1 a cable with an inner cable and a surrounding the inner cable guide body is known, which is formed of a plurality of interconnected joint parts. The existing plastic hinge parts have at one end a spherical cap-shaped extension and at the opposite ends a corresponding receptacle for the spherical cap extension of the adjacent hinge part.

From the DE 195 34 643 A1 a comparable, also modular construction of the guide body is known, wherein the individual members made of plastic on one side have a hemispherical recess and on the opposite side a hemispherical fitting for insertion into the receptacle of the adjacent member. A problem with these known guide bodies is the connection of the individual members with each other.

task The present invention is therefore the disadvantages described to avoid the prior art and to provide a guide body, which is simple is to configure, has a low weight and a simple Assembly allowed.

to solution the object it is provided according to the invention that the locking head each limb has a latching lock, whereby an unintentional Solve each other lockable limbs is difficult. The lock is as formed the locking head circumferential bead. By this measure is the risk of unintentional loosening in each other locked Limbs considerably reduced.

To In a first embodiment of the invention, the members are mutually opposed formed pivotable. This is a laying in bows with optimal wrap angle and thus low frictional resistance or high efficiency allows.

Preferably has each member in its interior a guide for the train body, so that damage to the displaceable pull body or the rope or the rope strand, if necessary protruding edges of the links are avoided.

Prefers are therefore the guides at least to one end, preferably to both ends of each link as funnel-shaped expandable channel, which also reduces the friction losses in or pressure movements of the tension body considerably reduced. Because the tensile body not on the entire leadership is also lesser due to the improved leverage effect Force required for operation the mechanically-flexible remote control is necessary.

In a particularly advantageous embodiment of the invention the locking head and the Rastpfanne adjacent links to each other adapted contact surfaces on, by the degree of pivotability is set. hereby is a laying in bows with different wrap angles possible. This measure leads to another Reduction of the frictional resistance of the tensile body within the guide and thus to a higher one Efficiency.

According to a further aspect of the invention, the links are at least in the region of the latching or snap connections made of an elastic material, in particular polymeric materials. As a result, the weight of the guide body according to the invention over conventional guide bodies can be reduced to one third.

From It is particularly advantageous if a member, preferably the end-side Links of the guide body end fittings, Connection elements, sockets and the like. Because the connection of the end fittings supporting end links in the same way as the connection of the other links of the management body, deleted so that required in the known guide bodies separate operation for the attachment of the end fittings.

Further Advantages and applications The present invention will become apparent from the following description an embodiment based on the drawing.

It demonstrate:

1 a view of a possible embodiment of a guide body according to the invention for a mechanical control cable in a schematic diagram,

2 a section through the control cable according to 1 along the section line AA,

3 the member of an embodiment of a guide body according to the invention for a mechanical control cable,

4 the limb according to 3 along the section line CC and

5 two locked together limbs according to 4 ,

The guide body 1 for a mechanical-flexible remote control according to 1 has several articulated links 2 . 3 made of plastic. The articulation between the limbs 2 . 3 takes place, as in particular 3 visible, by means of a ball joint connection. The locking head engages 5 of the one limb 2 . 3 under widening of the detent pan 6 of the associated member 3 respectively 2 in the manner of a snap connection. By using such snap connections, a modular construction of the guide body is realized. Of course, other releasable connections for the link chain are conceivable.

In the selected embodiment according to 1 and 2 are intermediate links 3 in a straight version. It is also conceivable that at the ends of the guide body 1 Links with corresponding fittings, also by means of ball joint or snap connection einbeziehungsweise are attached.

In the 3 to 5 is an embodiment of the individual members 2 . 3 of the leadership body 1 shown. The connection of the individual limbs 2 . 3 takes place, as in particular 5 can be seen by means of matched contact surfaces 10 . 11 the Rastpfanne 6 of the one limb 2 . 3 and the locking head 5 the correspondingly assigned member 2 . 3 , As with a ball joint connection engages the locking head 5 of the one limb 2 . 3 under elastic expansion of the latching pan 6 the correspondingly assigned member 2 . 3 in the manner of a snap connection. After the catch pan 6 a detent 9 has overcome, is a secure fit of the Rastpfanne 6 on the locking head 5 guaranteed.

In the embodiment according to 3 to 5 is the pivotability of individual members 2 . 3 not limited by stops. The degree of pivoting is in this case by the mating contact surfaces 10 . 11 of the locking head 5 and the detent pan 6 established. Once the pivoting limit has been reached, the latching pan becomes 6 of the one limb 2 . 3 through the locking mechanism 9 the correspondingly assigned member 2 . 3 widened, and the linked limbs 2 . 3 dissolve from each other.

By the appropriate choice of contact surfaces 10 . 11 of the locking head 5 and the detent pan 6 the minimum laying radius of the guide body is determined. At the same time minimizing the frictional resistance or maximizing the efficiency of the mechanical-flexible remote control with improved mobility of adjacent members 2 . 3 against each other. Advantage of this embodiment is in particular that align the members under load within the respective laying track without kinks or the like occur.
