DETAILED DESCRIPTION OF THE INVENTION

(11) FIG. 1 shows a perspective front side view of an article of furniture 100. That article of furniture 100 has two moveable furniture parts 2 which each include two furniture fronts 24. It is also possible to see a stationary furniture part 3 in the form of a furniture carcass as well as hollow spaces or cavities 101 arranged at that stationary furniture part 3 for accommodating the moveable furniture parts 2. The moveable furniture parts 2 can be folded together by the carriages 25 and the rail system 26, and are moveable by the arrangements 1 (not visible) according to the invention at least region-wise (partially) into the hollow space 101.

(12) FIG. 2a shows an embodiment by way of example of the present invention including two arrangements 1 according to the invention and a moveable furniture part 2 and a stationary furniture part 3 as a diagrammatic side view.

(13) The cables 6, 19 of the arrangements 1 are coupled to the guide devices 5, 18 by coupling devices 27, and are fixed to the stationary furniture part 3 by the fixing devices 7, 20 by way of the guide rails 4, 17.

(14) In this respect, a first fixing device 7 is arranged at an end 16 of the first guide rail 4, and a second fixing device 20 is arranged at an end 21 of the second guide rail 17. No fixing device is arranged at the ends 160, 210 of the guide rails 4, 17.

(15) It is further possible to see a synchronization device (synchronization rod) 23 which synchronizes the movements of the guide devices 5, 18.

(16) It is also possible to see the longitudinal direction L of the guide rails 4, 17.

(17) FIG. 2b shows an embodiment of the present invention including two arrangements 1 according to the invention and a moveable furniture part 2 and a stationary furniture part 3 as a diagrammatic side view in an overload situation (i.e., a situation in which the force applied to the cable is greater than the force applied to the cable during normal operation).

(18) It is possible to see an obstacle 28 which the moveable furniture part 2 has encountered. As a result, the moveable furniture part 2 and thus also the carrier 22, the synchronization device 23 as well as the two arrangements 1 according to the invention are no longer in a position normal to the longitudinal direction L of the guide rails 4, 17. The cables 6, 19 are thereby subjected to a tensile stress.

(19) There is an overload (excessive force) at the cables 6, 19, that is compensated for by the fixing devices 7, 20. Without the fixing devices 7, 20, damage could occur to the cables 6, 19.

(20) FIG. 3 shows a diagrammatic side view of a further embodiment of the present invention.

(21) In this case, fixing devices 7, 20 are arranged at all ends 16, 160, 21, of the guide rails 4, 17.

(22) The cables 6, 19 are respectively fixed to the stationary furniture part 3 at both sides by the associated fixing devices 7, 20 and by the guide rails 4, 17.

(23) The cables 6, 19 are further coupled to the guide devices 5, 18 by the coupling devices 27.

(24) FIG. 4 shows a diagrammatic side view of a further embodiment of the present invention.

(25) This embodiment differs from the embodiment of FIG. 3 by the provision of two cables 6, 60 and 19, 190 per guide device. Those cables 6, 60, 19, 190 are in turn fixed at the ends 16, 160, 21, 210 of the guide rails 4, by the associated fixing devices 7, 20 and by the guide rails 4, 17 at the stationary furniture part 3.

(26) In addition, the cables 6, 60, 19, 190 are coupled by the coupling devices 27 to the respective guide devices 5, 18.

(27) FIG. 5 shows a perspective view of an arrangement according to the invention.

(28) It is possible to see a guide device 5, 18 mounted moveably to the guide rail 4, 17, to an end of the fixing device 7, 20, and to the carrier 22.

(29) FIG. 5 further shows the at least one first cable 6, 19 mounted by the incision 12 to the mounting device 8. As shown in FIGS. 5 and 6, the mounting device 8 is mounted inside the guide rail 4, 17, and the guide rail 4, 17 has a recess to allow the cable 6, 19 to pass through the guide rail 4, 17 to the mounting device 8.

(30) FIG. 6 shows an exploded perspective view of an arrangement according to the invention.

(31) In particular, the structure of the fixing device 7, 20 can be clearly seen in this Figure.

(32) In this embodiment, the elastic member 9 which is in the form of a compression spring is arranged in a main body 10 of the fixing device 7, 20. It is also conceivable that the main body 10 is at least partially enclosed by the elastic member 9.

(33) The mounting device 8 and the slide 13 are assembled in one component in this embodiment. However, it is also possible for the mounting device 8 and the slide 13 to have a mutually separate structure.

(34) In this embodiment, the mounting device 8 has a slot-shaped incision for mounting the cable 6, 19. The shape of the incision 12, however, can be of any desired configuration.

(35) It is further possible to see the guide rail 4, 17 as well as the guide device 5, 18 and the carrier 22.

(36) FIG. 7 shows a side view of an embodiment of an arrangement 1 according to the invention. A part of the fixing device 7, 20 has been cut away for better understanding of the invention.

(37) The cable 6, 19 is coupled by the coupling device 27 to the guide device which is concealed by the guide rail 4, 17.

(38) In addition, the cable 6, 19 is connected to the fixing device 7, 20 by the slide 13 and the mounting device 8.

(39) In this embodiment, the cable 6, 19 is not arranged region-wise (partially) within the elastic member 9 which is in the form of a spring. However, the cable 6, 19 can be at least partially arranged within the spring 9 (i.e., within the coils of the spring) to minimize space requirements (i.e., promote a space-saving structure).

(40) The main body 10 of the fixing device 7, 20 is connected to the guide rail 4, 17 by the interfaces 15.

(41) It is further possible to see the carrier 22 connected to the guide device 5, 18 (not visible).

(42) FIG. 8 shows a side view of an embodiment of an arrangement 1 according to the invention in an overload situation (i.e., when force applied to the cables is greater than during normal operation). A part of the fixing device 7, 20 has been cut out for better understanding of the invention.

(43) In the overload situation, the cable 6, 19 is acted upon with a tensile force. That tensile force moves the mounting device 8 and thus the slide 13 against a force actuation afforded by the elastic member 9 in the form of the spring, parallel to a longitudinal direction of the guide device 4, 17.

(44) The overload occurring is therefore compensated for by the movement of the mounting device 8 and in addition by the elastic member 9.

(45) This, therefore, ensures that the cable 6, 19 is not damaged in the overload situation, and a connection of the cable 6, 19 to the stationary furniture part 3 is also not detached.
