Description

The invention relates to a cable duct for furniture, comprising a bracket and a cable rail that can be pivoted to the bracket, wherein at least two guide elements are formed between the bracket and the cable rail and the cable rail has at least four end positions through the guide element, namely a horizontal upper position, a horizontal lower position, a first inclined position and a second inclined position. Cable channels are commonly used for managing cables in office furniture. These channels are used, for example, for electrical wiring, power strips, or connecting devices. They prevent cable tangling and overall clutter, making it easy to keep things tidy around desks and office furniture. Currently, only cable channels are known that can be positioned using two snap-fit connections in the plastic holder. The cable channel remains in one snap-fit connection. It is removed from the other for pivoting and then rotates around the first snap-fit connection. This is how the DE 10 2011 011 645 A1 A piece of office furniture with a worktop and a cable duct, which has a cable duct cover flap that can be switched from a closed position covering the cable duct at least partially to an open position allowing access to the cable duct. These cable channels typically have three positions: a horizontal position, a first inclined position, and a second inclined position. These snap connections usually also allow the cable channel to be removed from the bracket. The disadvantage is that the cable tray, when pivoted, is freely movable around a pivot axis. When attempting to arrange cables in the tray, the user must hold them in place or secure them separately, otherwise they will slip out. Additionally, the tray itself must be held in position to prevent further pivoting (and emptying). This makes arranging cables in the cable channel complicated and cumbersome. In the DE 10 2010 048 002 A1 A junction box with at least one socket and/or a switch for recessing into a tabletop or floor is described, wherein a container is provided which is accessible via a container opening. This container opening can be closed with a lid. Furthermore, snap connections formed by plastic components are prone to breakage. This is primarily exacerbated by the aging of the plastic. The object of the present invention is to provide a cable duct which facilitates the arrangement of cables. This problem is solved according to the invention by the cable channel described above, in that the guide elements each have at least two cam guides and at least two guide pins that are slidable in slots of the cam guides, and that the guide pins are arranged in detent areas of the cam guide in all end positions. This makes it easy for a single user to install cables in the cable channel. No additional person or fixings are required, as the cable channel remains stable in its end positions solely due to its own weight. Because the guide elements each have at least two cam guides and at least two guide pins that can be moved in slots in the cam guides, a particularly durable and robust cable duct is obtained. The cam guides and the guide pins can be made of any durable material, for example, wood, metal, or plastic, and can therefore withstand even greater loads, such as the pressure exerted when plugs are inserted into the connector strip. Unlike conventional cable ducts, this load is not a problem for the cable duct according to the invention. This is advantageous in terms of safety and robustness. In a well-designed desktop, the cable channel beneath which is located has a cover. When the cover is removed—either by taking it off, sliding it, or pivoting it—the cable channel is freely accessible from above. Because the cable channel is more securely attached to the desktop, plugs can be easily inserted into power strips without the risk of the cable channel breaking. A particularly simple shape and smooth movement to and from the end positions result when the slots of the cam guides are essentially L-shaped. It is especially advantageous if the two elongated extensions of the L-shape are curved. The bracket and cable rail are particularly easy to connect during assembly if the slots of the guide rails are arranged in the cable rail and if the guide pins are arranged on the bracket. A possible alternative arises when the slots of the guide rails are arranged in the bracket and when the guide pins are arranged on the cable rail. To fix the end positions in a particularly simple way and to further increase stability, it is advantageous if the slots of the cam guides each have a detent area in their end area to receive the guide pin. This advantage also arises for another end position if the slots of the cam guides have a detent area in a central section to receive the guide pin. In the case of an L-shaped slot, the central section corresponds to its angle. To facilitate rotation into the inclined end positions and to largely prevent tilting, it is advantageous
