Abstract
Description
Technical Field
[0001] The present invention relates to a power supply device in the form described in the superordinate concept of claim 1, at least one extraction element, preferably a drawer or a shelf board, and an assembly comprising at least one such power supply device, and a method for assembling such an assembly into at least one furniture cabinet.
[0002] WO 2022 / 051786 discloses a power supply device for an extraction element.
[0003] In this solution, a socket is arranged on the rear wall of the drawer. This has several drawbacks: First, the extraction element always needs to have a rear wall, which limits the configuration shape of the extraction element. Furthermore, it is necessary to conduct the power to the socket by means of a technically laborious deflection device. At the same time, the deflection device makes the assembly of the drawer difficult because assembly steps are required behind the rear wall of the drawer. And finally, both the deflection device and the socket require a construction space between the rear wall of the drawer and the wall of the furniture cabinet facing the drawer, which reduces the nominal length available for the drawer.
[0004] The object of the present invention is to provide a power supply device that at least partially eliminates the known drawbacks of the prior art, is improved over the prior art, enables a space-saving and at the same time flexible structural form, especially for extraction elements, and can be easily assembled. Furthermore, it is desirable to provide an assembly comprising at least one extraction element and at least one such improved power supply device, and a method for assembling such an assembly into at least one furniture cabinet.
[0005] This object is solved by the features described in claims 1, 13 and 14.
[0006] Therefore, the power supply device has at least one conductive device that is mounted in contact with and / or within an opening provided at the bottom of the drawer element, which is horizontally oriented at the position in which the drawer element is used, and which is formed to pass power from the bottom opening to the power extraction device.
[0007] This eliminates the need for a power deflector known from the prior art, and allows at least one power extraction device to be positioned, for example, at the bottom of the drawer element and / or above the bottom, without relying on the back wall. This effectively limits the configuration shape of the drawer element; it simply needs to have a bottom.
[0008] Furthermore, the conductive device facilitates the assembly of the drawer element, as it is easier for the assembler to perform the assembly steps on the upper or lower side of the bottom of the drawer element than on the rear side of the back wall.
[0009] An assembly according to the present invention comprising at least one drawer element, preferably a drawer or shelf, comprises at least one power supply device according to the present invention, wherein the drawer element is coupled to a drawer rail of at least one drawer guide, preferably in the longitudinal direction, in the position of use, the drawer element has at least one bottom oriented horizontally in the position of use of the drawer element, the bottom having at least one, preferably cylindrical, opening, and at least one conductive device is mounted in contact with and / or within the bottom opening to pass power from the bottom opening to the power supply device.
[0010] A method according to the present invention for assembling at least one assembly according to the present invention into at least one furniture cabinet includes the following method steps, preferably in the order described, namely, the steps of assembling at least one drawer guide to the furniture cabinet via cabinet rails; mounting at least one conductive device adjacent to and / or inside the bottom opening; coupling at least one power extraction device to a drawer element; and coupling at least one drawer element to the drawer rail of the drawer guide.
[0011] Preferred embodiments are provided in the dependent claims.
[0012] Further details and advantages of the present invention will be described below in more detail with reference to the drawings, based on the description of the drawings. [Brief explanation of the drawing]

[0014] Figures 1 and 2 show an assembly 36 with at least one drawer element 2 formed as a shelf board in the illustrated embodiment.
[0015] This assembly 36 includes at least one power supply device 1, the details of which are shown in FIGS. 2 to 6 below.
[0016] The power supply device 1 serves to supply power, preferably 230V, to at least one drawer element 2 and includes at least one drawer guide 4 for movably supporting the drawer element 2 in the furniture cabinet 5. In this case, the drawer guide 4 has a cabinet rail 6 to be assembled to the furniture cabinet 5 and a drawer rail 7 to be coupled to the drawer element 2. In this case, the cabinet rail 6 and the drawer rail 7 are movably supported relative to each other, and preferably, at least one intermediate rail 8 is arranged between the cabinet rail 6 and the drawer rail 7 (see also FIG. 5).
[0017] The drawer element 2 is preferably coupled to the drawer rail 7 of at least one drawer guide 4 on its longitudinal surface 37 in the position of use. In the illustrated embodiment, one drawer guide 4 is positioned on each of the two longitudinal surfaces 37 of the drawer element 2 that are facing each other.
[0018] The power supply device 1 includes at least one power extraction device 9, preferably an outlet, coupled to the drawer element 2. A consumer appliance, such as a kitchen appliance, hair dryer, or charging cable, can be connected to this outlet.
[0019] The drawer element 2 has at least one bottom portion 29 that is oriented horizontally in the position where the drawer element 2 is used, and at least one, preferably cylindrical, opening 28 is formed in this bottom portion.
[0020] In the illustrated embodiment, at least one power extraction device 9 is located at least partially inside the bottom opening 28, meaning the power extraction device is a "recessed outlet".
[0021] The power extraction device 9 can be supplied with energy as follows:
[0022] At least one conductive device 27 is mounted in contact with and / or inside the bottom opening 28 in order to pass power from the bottom opening 28 to the power extraction device 9.
[0023] The conductive device 27 includes at least one holder 46 to be coupled to the lower surface 45 of the bottom 29 of the drawer element 2, and a bridging device 48 to be positioned within the bottom opening 28. In this case, the spacing 51 of the upper surfaces of the bridging device 48 relative to the holder 46 can be adjusted to accommodate the conductive device 27 with different thicknesses of the bottom 29 of the drawer element 2, preferably 5 mm to 30 mm.
[0024] In the illustrated embodiment, the bridging device 48 has at least one cylindrical body having male threads 53, and a holder 46 formed as a rotating member having female threads is rotatably supported on this cylindrical body.
[0025] Preferably, at least one cable guide 12 is provided to be connected to the pull-out guide 4, and this cable guide is formed to guide at least one power cable 13 to the power extraction device 9 (see also Figure 6).
[0026] The cable guide 12 may have, as shown in the illustrated example, at least one groove 25 into which at least one power cable 13 to be guided can be inserted, and at least one deflection device 26 that deflects the at least one power cable 13 to be guided by at least 90°.
[0027] Advantageously, at least one drag chain 33 is positioned between the cable guide 12 and the conductive device 27, and this drag chain is formed to guide at least one power cable 13 in the plane below the lead element 2 as the lead element 2 moves between a closed position and an open position. The concept of “drag chain” should be broadly interpreted to mean an energy guide that guides and protects the flexible cable and / or line. However, the drag chain does not necessarily have to consist of chain members.
[0028] The drag chain 33 may be connected to the conductive device 27 at connection point 38.
[0029] The stationary unit may be provided with at least one plug-in device 34, preferably located on a cabinet rail 6, through which the power supply unit 1 can be connected to the stationary power supply 35. In the illustrated example, the plug-in device 34 is located on a cable guide 12.
[0030] The plugging device 34 may be an adapter with specifications that differ from country to country.
[0031] The plug-in device 34 and the stationary power supply 35 can be connected via at least one power cable 89, which may be a cable with specifications that differ from country to country (see Figure 4).
[0032] Furthermore, the power supply device 1 may have at least one cable holder 32 that is removable and / or can be coupled to the cabinet rail 6 at its end face. For this purpose, for example, a plug-in connector may be provided.
[0033] Alternatively or supplementally, the power supply device 1 may have at least one circuit breaker, which includes at least one sensor for detecting the closed position of the drawer guide 4 or drawer elements 2,3, and at least one switching element that can interrupt the power supply in response to the signal from the sensor.
[0034] Preferably, the components of the power supply device 1 can be attached to the drawer guide 4 and / or drawer elements 2, 3 without tools, thereby providing retrofitting capability.
[0035] Another important advantage of the illustrated power supply device 1 is that most of its components are located in a space-saving manner beneath the bottom 29 of the drawer elements 2 and 3, which enables an inexpensive structural form.
[0036] The cable guide 12 may be attached to the pull-out guide 4 as follows.
[0037] The power supply device 1 is at least one drive device 14 to be connected to the drawer guide 4 or drawer elements 2, 3, and the drive device may have at least one attachment body 15 that is removably attached to the drawer guide 4 via at least one interface 16, and is configured to cooperate with the drive device 14 to transmit the force of the drive device 14 to one of the rails of the drawer guide 4 or to the drawer elements 2, 3, in which case the cable guide 12 and the attachment body 15 form a common component unit that is removably attached to the interface 16 of the drawer guide 4.
[0038] The interface 16 is positioned on the underside 19 of the cabinet rail 6, facing downward in the position where the drawer guide 4 is used, and / or has at least one locking device 20 and / or suspension device 21, which may enable a common component unit to be locked to and / or suspended from the drawer guide 4.
[0039] In the embodiment shown in Figure 6, a suspension device 21 is provided that can suspend a common component unit from a cabinet rail 6, and a locking device 20 is provided that can lock this component unit to the cabinet rail 6, preferably during rotational motion around a vertical axis.
[0040] The connecting body 15 has at least one protruding pin 22 or bolt that can be inserted into the opening 23 of the drive unit 14 (see also Figure 7).
[0041] A common component unit may include a substantially flat retaining metal sheet 24, which is connectable to or connected to the interface 16 of the connecting body 15, the cable guide 12, and / or the pull-out guide 4.
[0042] In this illustrated embodiment and in other embodiments, assembly 36 can be assembled to at least one furniture cabinet 5 (as schematically shown in Figure 1) as follows: at least one drawer guide 4 is assembled to the furniture cabinet 5 via a cabinet rail 6, preferably to a retaining web 70 of the cabinet rail 6; at least one power take-off device 9, 10, 11 is coupled to the drawer elements 2, 3; and at least one drawer element 2, 3 is coupled to the drawer rail 7 of the drawer guide 4.
[0043] Optionally, the following method steps may be provided individually or in combination: at least one connecting body 15 and at least one cable guide 12 are removably attached to the interface 16 of the pull-out guide 4; at least one drive unit 14 is connected to the pull-out guide 4 or the pull-out elements 2,3; at least one conductive device 27 is mounted in contact with and / or inside the bottom opening 28; and / or at least one power take-off device 9,10,11 is coupled to the pull-out elements 2,3 using at least one retaining device 30,31 in contact with and / or inside the bottom opening 28 and / or above the bottom opening 28.
[0044] Figure 7 shows a significantly simplified schematic diagram of the drive unit 14.
[0045] The drive unit 14 includes at least one energy accumulator 17, preferably at least one spring device, and at least one drive element 18 that can be driven by the energy accumulator, the drive element being connectable to the train 15.
[0046] The drive unit 14 may be formed as an ejector device for pushing the drawer rail 7 or the drawer elements 2, 3 to be coupled to the drawer rail from the closed position to the open position relative to the cabinet rail 6.
[0047] The drive unit 14 may be formed as an alternative or supplementary retraction device 71 that works in cooperation with the actuator 72.
[0048] In the embodiment shown in Figure 3, both the ejector device 14 and the retraction device 71 are provided. These can be formed modularly or within a single common component unit.
[0049] The cable guide 12 can form a single common component unit together with the traction unit 15 and / or the actuator 72.
[0050] Figures 8 to 13 show another embodiment of the conductive device 27.
[0051] The conductive device 27 has at least one connection point 38 for at least one power cable 13 and / or at least one drag chain 33, preferably at least one connection point 38 having at least one plug-in connection 39 and / or being arranged in a plane parallel to the bottom 29 of the lead-out elements 2,3.
[0052] The plug-in connector 39 (see Figure 9) facilitates the assembly of the drawer elements 2 and 3 by allowing the drawer element 2 to be mounted on the drawer rail 7, and then the conductive device 27 to be connected to the power cable 13 and / or drag chain 33.
[0053] At least one adjustment device 40 is provided that can adjust the position of the connection points 38 relative to the base 42 of the conductive device 27 and / or the spacing 44 of the connection points 38 relative to the lower surface 45 of the bottom 29 of the drawer elements 2,3.
[0054] This has the advantageous technical effect that the conductive device 27 can be adjusted to each different drawer guide 4. Different drawer guides 4 may differ from one another in their structural height, particularly in the distance between the underside of the cabinet rail 6 and the mounting web of the drawer rail 7.
[0055] In the illustrated embodiment, the adjustment device 40 has an adjustment screw that allows the connection point 38 to be displaced vertically relative to the base 42 (see Figure 9). To facilitate adjustment, markings including, for example, at least two arrows may be provided.
[0056] The power extraction device 9 is provided with at least one retaining device 30 that is formed to contact and hold within an opening 28 provided in the bottom 29 of the drawer elements 2 and 3, which is oriented horizontally at the usage position of the drawer elements 2 and 3.
[0057] At least one retaining device 30 is located on or can be located on the conductive device 27, as in the illustrated example, preferably the retaining device 30 is slidably located on the conductive device 27.
[0058] A groove 81 can be provided for sliding support.
[0059] The holding device 30 facilitates the assembly of the conductive device 27 by holding the conductive device 27, which has been introduced into the bottom opening 28 from above, so as not to slide further down.
[0060] The retaining device 30 includes at least one retaining yoke, which is preferably screw-fixed, to be coupled to the upper surface 55 of the bottom 29 of the drawer elements 2,3.
[0061] The holding device 30 is formed in a fork shape at least partially and at least partially surrounds the bottom opening 28 in the assembly position.
[0062] The power extraction device 9 may be connectable to and / or fitted over the retaining device 30 via at least one locking connection portion 58 and / or at least one screw connection portion 59.
[0063] In the illustrated embodiment, a locking connection portion 58 is provided that functions between the frame 78 of the power extraction device 9 and the holding device 30. The central body 90, which is located inside the frame 78 in the assembled position, can be fitted over the holding device 30 and the bridging device 49 which is connectable to or connected to the holding device from above, and can be fixed by the snap connection portion 79.
[0064] The conductive device 27 includes at least one holder 47 to be coupled to the lower surface 45 of the bottom 29 of the drawer elements 2,3, preferably screw-fixed, and a bridging device 49 to be positioned within the bottom opening 28. In this case, the spacing 51 of the upper surfaces 52 of the bridging device 49 can be adjusted relative to the holder 47 to accommodate the conductive device 27 with different thicknesses of the bottom 29 of the drawer elements 2,3, preferably 5mm to 30mm.
[0065] The bridging device 49 may be slidably supported within and / or in contact with the holder 47. Figures 10 and 12 show, exemplarily, two different positions of the bridging device 49 relative to the holder 47, depending on two different thicknesses 88 of the base 29.
[0066] To prevent the holder 47, or the base 42 on which the holder 47 is formed, from sliding downward during assembly, the bridging device 49 may have at least one restraining device 80, for example, having a spring-elastic hook.
[0067] A corresponding holder 56 is positioned or can be positioned on the upper surface 52 of the bridging device 49, which is to be coupled to the upper surface 55 of the bottom 29 of the draw-out elements 2 and 3.
[0068] In the illustrated embodiment, the conductive device 27 is fixed to the bottom 29 from below via a holder 47 and from above via a corresponding holder 56, preferably by screw fixing.
[0069] For ease of viewing, electrical wiring is not shown in the diagrams. As a representative example, a conductor 83 is roughly shown in Figures 10 and 24, and this conductor makes a conductive connection at connection point 38 to the power extraction device 9 or plug-in device 57.
