Pull-out element with power supply unit

Description

[0001] The invention relates to an arrangement according to the preamble of claim 1, comprising at least one pull-out element, preferably a drawer or a shelf, and at least one power supply device. The invention further relates to a method for mounting such an arrangement on at least one furniture carcass.

[0002] WO 2022 / 051786 A1 discloses a power supply device for extension elements. US 2022 / 216012 A1 also discloses a power supply device for extension elements.

[0003] This solution involves integrating a power outlet into the back panel of the drawer. This has several disadvantages: firstly, the drawer unit must always have a back panel, which limits its design. Secondly, the current needs to be routed to the outlet via a technically complex redirection device. This device also complicates drawer installation, as it requires work behind the drawer's back panel. Finally, both the redirection device and the outlet occupy space between the drawer's back panel and a wall of the cabinet facing the drawer, resulting in a shorter overall drawer length.

[0004] The object of the present invention is to at least partially overcome the disadvantages known from the prior art and to provide an arrangement with at least one extension element and at least one power supply device that is improved compared to the prior art, which in particular enables a space-saving and at the same time flexible design of the extension element and is associated with simplified assembly. Furthermore, a method for mounting such an arrangement on at least one furniture carcass is to be provided.

[0005] This problem is solved by the features of claims 1 and 13.

[0006] Accordingly, the at least one power supply device of the arrangement comprises at least one holding device which is designed to hold the power extraction device on and / or in and / or above an opening in a base of the extension element which is horizontally oriented in the operating position of the extension element.

[0007] This makes it possible to dispense with the known current deflection device and to arrange at least one current extraction device independently of a rear wall, e.g., in the base of the pull-out element and / or above the base. The design of the pull-out element is thus practically unrestricted. Only a base is required.

[0008] Furthermore, the at least one holding device facilitates the assembly of the pull-out element, as it is easier for an installer to carry out assembly steps above or below the base of the pull-out element than behind the back panel.

[0009] The arrangement according to the invention comprises, in addition to at least one power supply device, at least one extension element, preferably a drawer or a shelf, wherein the extension element is connected in a use position, preferably on a longitudinal side, to the drawer rail of the at least one extension guide, the extension element has at least one base which is horizontally oriented in the use position of the extension element, in which at least one, preferably cylindrical, opening is formed, wherein the power extraction device is held by means of the at least one holding device on and / or in and / or above the base opening.

[0010] The inventive method for mounting at least one inventive arrangement on at least one furniture carcass comprises the following process steps, preferably in the specified chronological order: the at least one extension guide is mounted on the furniture carcass via the carcass rail, the at least one current extraction device is connected to the extension element by means of the at least one holding device on and / or in and / or above the bottom opening, and the at least one extension element is connected to the drawer rail of the extension guide.
