Description

[0022] The invention will now be explained below on the basis of an exemplary embodiment, with reference to the figures. Here, additional advantages, features and designs of the invention are described.

[0023] In the figures:

[0024] FIG. 1 and FIG. 2 show a cable holder according to the invention with an arranged running element,

[0025] FIG. 3 shows a cable holder according to the invention with an arranged running element in a diagonal perspective with cable.

[0026] In FIGS. 1 to 3, a cable holder 1 according to the invention is shown interacting with a running element 9 according to the invention.

[0027] In the exemplary embodiment, the cable holder 1 for an anti-fall device has a console 4 for the secure functional arrangement on a building structure and a cable retainer 5.

[0028] The cable retainer 5 and the console 4 are here connected to each other. The cable retainer 5 is reversibly rotatably supported on the console 4. The axis of rotation 2 of the cable holder 4 or the cable retainer 5 is laid offset parallel to a cable 3 as shown in FIG. 3. In order to ensure reversibility, the cable retainer and/or the console 4 has one spring element 6.

[0029] Further, the cable retainer 5 has a cable guide 7 and a connecting piece 8, wherein the cable guide 7 connects to the connecting piece 8 as shown in the figures. The connecting piece 8 has a curved section 10 with a running element 9 as a separate component, offset parallel in the cable direction. The curved section 10 of the connecting piece 8 points in the direction of rotation of the cable holder 1 in relation to an initial position of the cable holder 1. The initial position is shown in FIG. 1.

[0030] The curved section 10 is elevated in the direction of rotation, as a result of which a spring effect of the connecting piece 8 and thus of the cable retainer 5 is guaranteedeven when this is generally lower in relation to a rotatable support. Thus, in addition to the reversible rotatable support of the cable retainer 5, a spring effect of said retainer is provided.

[0031] Furthermore, the curved section 10 of the connecting piece 8 forms a chamfer 11 as the first guide 13 for the running element 9, so that this can glide over the cable holder 1 in a largely jolt-free manner.

[0032] Further, the cable guide 7in the direction of rotation of the cable holder 1, more precisely its cable retainer 5, in relation to the known initial position according to FIG. 1has, at a transition point to the connecting piece 8 with its curved section 10 and opposite the chamfer 11, an elevation, which is designed in the exemplary embodiment as a cam 12. Thus, together with the curved section 10 of the connecting piece 8, a second guide 14 is formed, which further supports the largely jolt-free gliding of the running element 9 over the cable holder 1.

[0033] The first guide 13 and the second guide 14 are here formed differently with regard to their cross-section profile.

[0034] In the exemplary embodiment, the running element 9 that is arranged or arrangeable on the cable holder 1 has, as is known, a longitudinal slit 15 running parallel to the cable 3 of the cable holder 1, FIG. 3. Here, the longitudinal slit 15 is laid in a defined angular position of approx. 125 in relation to a retainer 16 for a known carabiner of a fall arrest device. The running element 9 has a first longitudinal slit edge 17 and a further longitudinal slit edge 18. The first longitudinal slit edge 17 is designed with regard to its form to correspond with the first guide 13 of the cable holder 1, and the second longitudinal slit edge 18 is designed with regard to its form to correspond to the second guide 14 of the cable holder 1. Due to the different form of the first guide 13 and the second guide 14, the first longitudinal slit edge 17 and a further longitudinal slit edge 18 also have a different design.

[0035] Here, it is provided that the first longitudinal slit edge 17 interacts with the first guide 13 and the second longitudinal slit edge 18 interacts with the second guide 14 in an easy clearance fit, when the running element 9 lies on the cable holder 1, as it does for a gliding over of the cable holder 1 and thus also of its cable guide 7 by the running element 9.

[0036] This design of the components, which corresponds to the form, means, as already explained above, that a form fit of the running element 9 with the cable holder 1 with a clearance fit is ensured when the running element 9 lies on the cable holder 1. The form fit prevents or minimizes canting. If tensile forces from a cable 3 of a fall arrest device laid on the retainer 16 are then emitted in the direction of rotation of the cable retainer 1, this leads to the rotation of the cable retainer 5, and if due to the design the reversible rotation is limited at a stop or other element, in other words, by the design of the spring element 6, this enables the described spring effect of the curved section 10 or the connecting piece 8 to have an additional effect after such a stop has been reached. This provides a reduction of the risk of canting of the running element 9 at an angle to its running direction. Thus, a reversibly movable, rotatable guide is created, which simplifies a guiding of the running element 9 over the cable holder 1.
