DETAILED DESCRIPTION OF THE INVENTION

A piece of furniture 100, which can comprise different component parts, for example several compartments inside the piece of furniture 100, is represented schematically in a perspective view in FIG. 1. The stationary furniture part 3 is formed by a furniture carcass.

At the side of the piece of furniture 100, a cavity 101 is provided which is formed of two furniture walls 101a spaced apart from each other. A movable furniture part 2 in the form of a folding sliding door can be concealed in the cavity 101 in the folded-up state. If the folding sliding door is spread open, it conceals the interior of the piece of furniture 100.

The folding sliding door is composed of two partial flaps, which are folded up in the position according to FIG. 1. From this folded-up position, the folding sliding doors 2 can be transferred to a spread-open position, in which the partial flaps form an angle which is greater than 0°.

A further part of the piece of furniture 100 is arranged adjoining the cavity 101, for example a cupboard. If the folding sliding door is in a spread-open position and the further part of the piece of furniture 100 is closed, the folding sliding door and the further part of the piece of furniture 100 form a continuous furniture front.

FIG. 2 shows an exploded representation of a piece of furniture 100 with an assembly 1 according to the invention in a perspective view. For better understanding the second furniture wall 101a of the cavity 101 is not represented. It is evident that the folding sliding door is in a fully spread-open position. Furthermore, two guide systems 4, 5 and a furniture wall 3 can be seen. A support 6 is also evident.

FIG. 3 shows a part of a piece of furniture 100 with an assembly 1 according to the invention. A support 6 can again be seen, which is mounted displaceable on the two guide systems 1, 5.

A compensation device 7 consisting of a cable pull device 8 and a pivot lever mechanism 12 is also represented. The pivot lever mechanism consists of a first 12a and a second pivot lever 12b. The first pivot lever 12a is arranged on the guide system 4 and displaceable on the support 6. The second pivot lever 12b is arranged on the support 6 and centrally on the first pivot lever 12a. The cable pull device 8 comprises a cable 8a and guide pulleys 8b, which are arranged on the furniture wall 101a and/or on one of the two guide systems 1, 5.

The cable tensioning device 9 is arranged on the rear side of the support 6 and therefore not evident.

FIG. 4 shows an exploded representation of a cable tensioning device 9 according to the invention. A main body 9c can be seen, on which a display element 11 is rotatably mounted.

The display element 11 has an indicator 11a, a tensioning element 11b as well as an actuating lever 11c. In the present embodiment, the display element is formed in one piece. However, a multi-part display element can also be provided.

In the present embodiment, the one-piece display element 11 is implemented in the color which the indicator 11a is also to have. However, it can also be provided that the indicator 11a is specially colored or else has stickers or the like.

A force is applied to the display element 11 via a tension spring 10a. The display element 11 can be twisted by hand via the actuating lever 11c.

Furthermore, a housing 9d can be seen, which has a recess 10b. The indicator 11a is visible in the recess 10b in the assembled state with sufficient cable tension.

A fixing element 9a is furthermore formed on the main body 9a. The second fixing element 9a is arranged on the first fixing element 9a via actuating elements 9b in the form of screws. The cable can be clamped and thus fixed between the fixing elements 9a.

FIGS. 5a to 5h show a cable tensioning device according to the invention in a perspective front view and FIGS. 6a to 6h in a perspective rear view during a step of a method according to the invention.

FIGS. 5a to 5f and 6a to 6f show how a cable 8a is inserted into the cable tensioning device 9. The cable 8a is first guided through an opening in the housing 9d and then inserted into the housing 9d (FIGS. 5a to 5c and 6a to 6c respectively). The housing 9d also serves as a cable guide for the cable 8a.

The main body 9c is in each case not represented in FIGS. 6a to 6c. It can be seen that the display element 11 is not moved.

In a next step, the display element 11 is twisted against the force applied by the energy storage mechanism 10 via the actuating lever 11c. The cable 8a can then be guided through between the indicator 11a and the tensioning element 11b (FIGS. 5d and 6d).

Then the cable 8a is guided through between the clamping elements 9a and out of the housing 9d (FIGS. 5e/f and 6e/f). Meanwhile, the display element 11 is held in the twisted position via the actuating lever 11c.

If the cable 8a is arranged in the cable tensioning device 9 in such a way, the actuating lever 11c can be released. The display element 11 is twisted in the direction of the original position because of the energy storage mechanism 10a. In the process, the tensioning element 11b presses against the cable 8a and thus represents an operative connection between the display element 11 and the cable 8a. The cable 8a is thereby lightly clamped at the same time, which prevents the cable 8a from slipping out of the cable tensioning device 9, for example during a transport process.

If the cable 8a is now tensioned, the cable presses against the tensioning element 11b because of the tension and in the process twists the display element 11 against the force applied by the energy storage mechanism 10a. If the cable tension is large enough, the display element 11 is twisted to the extent that the indicator 11a can be seen through the recess 10b. The display device 10 indicates a sufficient cable tension.

The cable can now be fixed via the clamping elements 9a while maintaining the cable tension, by actuating the actuating elements 9b (FIGS. 5g/6g). In the last step, a cable end of the cable 8a can be stowed in an opening of the support 6 (FIGS. 5h/6h).

FIG. 7 shows a flow diagram of a preferred method 200 for installing an assembly 1 according to the invention on a furniture wall 3. The order of the method steps 201 to 204 of the method 200 can be seen.
