Technical Field

[0001] This utility model relates to a system furniture with a shelf fixing device, and more specifically to a system furniture with a shelf fixing device that allows for adjustment of shelf height while permitting electrical connection, facilitates shelf installation and disassembly, and prevents shelf base from detaching from the connection part.

[0002] Another aspect of this utility model discloses a system furniture with a rod connection device. More specifically, it relates to a system furniture with a rod connection device that allows for height adjustment of the hangers while permitting electrical connection, facilitates easy installation and disassembly of the hangers, and allows for the continuous installation of multiple hangers at the same height.

[0003] Another aspect of this utility model discloses a system furniture with an electrode support device. More specifically, it relates to a system furniture with an electrode support device that allows for adjustable shelf height, easy installation and removal of hangers, and permits electrical connection via the electrode support device without the use of electrical wires. Background Technology

[0004] Typically, lighting fixtures are installed in furniture such as beds, desks, display cabinets, and dressing tables to enhance the aesthetics or illuminate specific spaces. Lighting fixtures installed on furniture can improve the visual appeal and provide functional benefits while illuminating a particular area.

[0005] Lighting fixtures with diffusers can be installed in interior cabinets, such as display cases or built-in cabinets with shelves or hanging racks. Installing lighting fixtures in interior cabinets can enhance their aesthetic appeal and illuminate specific areas. These fixtures can be mounted on shelves or hanging racks within the cabinet. However, installing lighting fixtures on shelves or hanging racks presents the following problems.

[0006] When installing lighting fixtures on shelves or hangers, one point on the shelf or hanger where the lighting fixture is installed must be connected to an external power source. One point on the shelf where the lighting fixture is installed can be connected to an external power source via an electrical wire.

[0007] However, when a shelf is connected to the outside via a wire, there is a problem that the shelf height is difficult to adjust due to the wire. Specifically, if the wire is too short, it is difficult to increase the shelf height; if the wire is too long compared to the shelf height, it is unsightly.

[0008] Additionally, when a point on the shelf is connected to the outside via an electrical wire, it can be difficult to locate the short circuit. If a lighting fixture installed on the shelf malfunctions, the short circuit must be found, but because a point on the shelf is connected to the outside via a single electrical wire, it can be challenging to locate the short circuit.

[0009] In addition, if the modular shelves do not have a fixing device, there is a risk that they may accidentally fall off during use.

[0010] In addition, when multiple hangers are installed, there is a problem that they cannot be installed continuously at the same height. Utility Model Content

By coupling the connecting bracket 120 to the base plate 110 and coupling the support column 140 to the connecting bracket 120, the support column 140 can be installed vertically relative to the base plate 110.

[0096] The second electrode 150 extends along the height direction of the support portion 140. The second electrode 150 includes a cathode and an anode, and may consist of a pair of electrodes.

[0097] When the support portion 140 is attached to the connecting bracket 120, the second electrode 150 can contact the first electrode 130. When the support portion 140 is attached to the connecting bracket 120 and the second electrode 150 is in contact with the first electrode 130, the cathode of the second electrode 150 can contact the cathode of the first electrode 130, and the anode of the second electrode 150 can contact the anode of the first electrode 130. Thus, the first electrode 130 and the second electrode 150 can be electrically connected.

[0098] According to an embodiment of the present invention, the first electrode 130 includes a first electrode connecting portion 131, which protrudes upward from the connecting bracket 120 and bends outward. According to an embodiment of the present invention, the second electrode 150 may be disposed inside the support portion 140 and is composed of a thin film extending along the height direction of the support portion 140.

[0099] Reference Figure 3 and Figure 4 When the support portion 140 is attached to the connecting bracket 120, the first electrode connection portion 131 contacts the second electrode 150 composed of a thin film, so that the first electrode 130 and the second electrode 150 can be electrically connected.

[0100] The first electrode connection portion 131 may include a cathode and an anode. When the second electrode 150, which is composed of a thin film, comes into contact with the first electrode connection portion 131, the cathode of the second electrode 150 may come into contact with the cathode of the first electrode connection portion 131, and the anode of the second electrode 150 may come into contact with the anode of the first electrode connection portion 131.

[0101] Thus, according to the present invention, the system furniture equipped with a shelf fixing device can be electrically connected by simply combining or assembling the support column 140 to the connecting bracket 120, thereby bringing the first electrode 130 and the second electrode 150 into contact.

[0102] According to an embodiment of the present invention, the first electrode connection portion 131 may be composed of an elastic component, and before the support portion 140 is coupled to the connecting bracket 120, the first electrode connection portion 131 may be in an open state to the outside.

[0103] Reference Figure 4 When the support portion 140 is attached to the connecting bracket 120, the first electrode connection portion 131, which is open to the outside, can be gathered inward through the support portion 140. That is, the support portion 140 can gather the first electrode connection portion 131, which is open to the outside, to the inside and can be pressed into the connecting bracket 120.

[0104] When the first electrode connection portion 131 converges inward through the support portion 140, an elastic restoring force occurs in the first electrode connection portion 131, which is composed of an elastic member. When the support portion 140 is attached to the connecting bracket 120, the first electrode connection portion 131 is elastically compressed to open outward by the elastic restoring force.

[0105] Thus, when the support portion 140 is connected to the connecting bracket 120, the first electrode connection portion 131 is elastically compressed to open outward, so that the first electrode connection portion 131 is firmly in contact with the second electrode 150.

[0106] According to an embodiment of the present invention, the support portion 140 is provided with a track 141 having a plurality of connecting holes 142 along the height direction of the support portion 140. The connecting holes 142 are holes for engaging the hook portion 162 (described later), and may be holes passing through the track 141.

[0107] The track 141 may have a plurality of connecting holes 142 along the height direction of the support portion 140. The track 141 may be, but is not limited to, a component that is inserted into and connected to the support portion 140. The track 141 may also be integrally manufactured with the support portion 140.

[0108] Reference Figure 5 The shelf 160 includes: a connecting portion 161 having a plurality of hook portions 162 formed in the shape of hooks for insertion into the connecting holes 142 of the track 141; and a base portion 163 disposed between two of the connecting portions 161.

[0109] The connecting portion 161 of the shelf 160 may be composed of a cantilever, and one side of the connecting portion 161 may be provided with a plurality of hook portions 162 formed in a hook shape. The connecting portion 161 may be respectively provided on both sides of the shelf 160.

[0110] Reference Figure 3 and Figure 6 The connecting portion 161 can be coupled to the support portion 140 by inserting the hook portion 162, which is formed in a hook shape, into the coupling hole 142. The hook portion 162 can be coupled to any one or more of the plurality of coupling holes 142.

[0111] According to an embodiment of this utility model, the height at which the connecting part 161 engages with the support part 140 is adjusted by changing the position of the hook part 162 engaging with the plurality of engaging holes 142. Thus, the height at which the shelf 160 engages with the support part 140 can be adjusted.

[0112] According to an embodiment of the present invention, the connecting portion 161 may be provided with a third electrode 170. Specifically, the third electrode 170 is disposed on the hook portion 162 of the connecting portion 161, and when the connecting portion 161 is connected to the support portion 140, the second electrode 150 can contact the third electrode 170. The third electrode 170 includes a cathode and an anode, and is composed of a pair of electrodes.

[0113] When the connecting portion 161 is attached to the support portion 140, the cathode of the third electrode 170 can contact the cathode of the second electrode 150, and the anode of the third electrode 170 can contact the anode of the second electrode 150. Thus, the second electrode 150 and the third electrode 170 can be electrically connected.

[0114] As described above, the second electrode 150 is composed of a thin film and extends along the height direction of the support portion 140. Therefore, even at any height at which the shelf 160 is attached to the support portion 140, the second electrode 150 can contact and electrically connect with the third electrode 170.

[0115] According to an embodiment of the present invention, the third electrode 170 may include a third electrode connecting portion 171 that is bent and protrudes outward from the hook portion 162. (See also...) Figure 6 The third electrode connection portion 171 can be bent and protrude outward from the hook portion 162.

[0116] When the hook 162 is inserted into the connecting hole 142 of the track 141, the third electrode connecting part 171 protruding from the hook 162 contacts the second electrode 150, and the third electrode 170 and the second electrode 150 can be electrically connected.

[0117] The third electrode connection portion 171 may include a cathode and an anode. When the second electrode 150, which is composed of a thin film, contacts the third electrode connection portion 171, the cathode of the second electrode 150 may contact the cathode of the third electrode connection portion 171, and the anode of the second electrode 150 may contact the anode of the third electrode connection portion 171.

[0118] Thus, according to the present invention, the system furniture equipped with a shelf fixing device can electrically connect the second electrode 150 and the third electrode 170 by simply joining or assembling the hook portion 162 of the shelf 160 to the support portion 140.

[0119] Since the second electrode 150 of this embodiment is composed of a thin film extending along the height direction of the support portion 140, the third electrode 170 and the second electrode 150 can be contacted and electrically connected even if the hook portion 162 is attached to any height of the support portion 140.

[0120] That is, even if the hook 162 is inserted into any of the plurality of engagement holes 142 for engagement, the second electrode 150 and the third electrode 170 can contact and be electrically connected. Thus, even if the height of the shelf 160 relative to the support 140 is adjusted, the second electrode 150 and the third electrode 170 will contact and be electrically connected.

[0121] According to an embodiment of the present invention, the third electrode connection portion 171 may be composed of an elastic component, and the third electrode connection portion 171 may be in an open state before the hook portion 162 is inserted into the connecting hole 142.

[0122] When the hook portion 162 is inserted into the connecting hole 142, the outwardly open third electrode connection portion 171 can be gathered inward through the support portion 140. That is, the hook portion 162 can gather the outwardly open third electrode connection portion 171 inward and press it into the inside of the support portion 140 through the connecting hole 142.

[0123] When the third electrode connection portion 171 converges inward through the support portion 140, an elastic restoring force occurs in the third electrode connection portion 171, which is composed of an elastic member. When the hook portion 162 is inserted into the connecting hole 142, the third electrode connection portion 171 is elastically compressed to open outward by the elastic restoring force.

[0124] Thus, when the hook portion 162 is inserted into the connecting hole 142, the third electrode connection portion 171 is elastically compressed to open outward, firmly contacting the second electrode 150.

[0125] The base portion 163 of the shelf 160 is disposed between the two connecting portions 161. The base portion 163 may be plate-shaped and may be the base plate of the shelf 160.

[0126] According to an embodiment of the present invention, a system furniture equipped with a shelf fixing device may include a light source 180 disposed on the shelf 160 and connected to the third electrode 170. The light source 180 is electrically connected to the third electrode 170, and the light source 180 may be disposed at various points on the shelf 160.

[0127] The lighting 180 can be connected to the third electrode 170 via wires or other electrical connection devices, and the lighting 180 can be composed of a diffuser plate. However, it is not limited to this, and the lighting 180 can be arranged on the shelf 160 in various forms. And as can be predicted from its shape, the lighting 180 can also be used as a clothes hanger rod.

[0128] The first electrode 130, located on the connecting bracket 120, receives power through the electrical connection line 121, and the power supplied to the first electrode 130 is transferred to the second electrode 150. The power transferred to the second electrode 150 is transferred to the third electrode 170, and the power transferred to the third electrode 170 is transferred to the illumination 180, from which light can be emitted.

[0129] According to an embodiment of the present invention, the connecting portion 161 and the base portion 163 of the shelf 160 can be separate components. First, the connecting portion 161 is attached to the support portion 140, and the base portion 163 is installed between the two connecting portions 161, allowing the shelf 160 to be installed in system furniture.

[0130] When the base portion 163 is installed between the two connecting portions 161, the base portion 163 can be lifted and installed between the two connecting portions 161. At this time, without a separate device to secure the base portion 163, there is a risk that the base portion 163 may be lifted and detached from the connecting portion 161.

[0131] The shelf fixing device 200 and the locking member 164 are used to lift the base portion 163 and prevent it from falling off the connecting portion 161, and to fix the base portion 163 to the connecting portion 161. (Refer to...) Figure 7 The shelf fixing device 200 can be disposed on the connecting part 161, as shown in the figure. Figure 8 The locking component 164 may be disposed on the base portion 163.

[0132] According to an embodiment of the present invention, the shelf fixing device 200 includes a housing 210, a switch 220, and a sliding part 230. The housing 210 has an internal space and is connected to the connecting part 161.

[0133] Reference Figure 7 The housing 210 can be attached to the inner side of the connecting part 161 by screws or the like. The switch 220 is disposed in the housing 210, and by operating the switch 220, the sliding part 230 protrudes outward from the housing 210.

[0134] Reference Figure 9(a) The sliding part 230 may be disposed inside the housing 210 and configured not to protrude outside the housing 210. This state may be that the shelf fixing device 200 is in an unlocked state.

[0135] Subsequently, when the switch 220 is pressed, the sliding part 230 can protrude outward from the housing 210, as... Figure 9 As shown in (b). This state can be that the shelf fixing device 200 is in a locked state.

[0136] Furthermore, when the switch 220 is pressed again, the sliding part 230 can be reintroduced into the housing 210 and achieve a state where it does not protrude out of the housing 210.

[0137] like Figure 8 and Figure 10 As shown, the locking component 164 is disposed on the side of the base portion 163, and the locking component 164 includes an insertion space 165 into which the shelf fixing device 200 is inserted and a locking protrusion 166 disposed below the insertion space 165.

[0138] Reference Figure 11 (a) and Figure 11 (b) When the base portion 163 is lifted and installed between the two connecting portions 161, the shelf fixing device 200 can be inserted into the insertion space of the locking member 164. At this time, as Figure 11 As shown in (a), the sliding part 230 of the shelf fixing device 200 may not protrude to the outside of the housing 210.

[0139] When the base portion 163 is lifted and installed between the two connecting portions 161, the sliding portion 230 is operated by the switch 220. By operating the switch 220, the sliding portion 230 can protrude outward from the housing 210.

[0140] When the sliding part 230 protrudes outward from the housing 210, the sliding part 230 can be positioned above the locking protrusion 166, such as... Figure 11 As shown in (b). Figure 11 As shown in (b), since the sliding part 230 is positioned above the locking protrusion 166, the base part 163 can be lifted and prevented from falling off the connecting part 161.

[0141] Specifically, when the base portion 163 is lifted, the locking protrusion 166 of the locking member 164 provided on the base portion 163 contacts the sliding portion 230, so that the base portion 163 can be lifted and prevented from disengaging from the connecting portion 161.

[0142] According to an embodiment of the present invention, the locking member 164 can be combined with the base portion 163, and the locking member 164 can also be integrally formed with the base portion 163.

[0143] When the base portion 163 is made of wood, the locking member 164 can be manufactured separately and attached to the side of the base portion 163. When the base portion 163 is made of a component with hardness such as iron, the locking member 164 can be integrally formed with the base portion 163.

[0144] Specifically, when the base portion 163 is composed of a component with a hardness such as iron, the locking component 164 is integrally formed with the base portion 163 and the structure of the locking component 164 is formed on the side of the base portion 163.

[0145] In the following text, the method of moving the sliding part 230 is described in detail according to the operation of the switch 220 of the shelf fixing device 200 based on an embodiment of the present invention.

[0146] Reference Figure 12 (a) and Figure 12 (b) According to the embodiment of the present invention, the switch 220 may be provided with a movable protrusion 221 protruding outward from the switch 220. The movable protrusion 221 may be a rod-shaped protrusion protruding to both sides of the switch 220.

[0147] According to an embodiment of the present invention, the shelf fixing device 200 may include a fixing part 240 inserted into the housing 210 and provided with a moving groove 241 extending in one direction to insert the moving protrusion 221.

[0148] The fixing part 240 is inserted into the housing 210, and its interior has space for the switch 220 to move. The fixing part 240 has moving slots 241 on both sides, and the moving protrusion 221 can be inserted into the moving slots 241. When the switch 220 is inserted into the fixing part 240, the moving protrusion 221 can be inserted into the moving slot 241.

[0149] The movable groove 241 extends in one direction, and the movable groove 241 can be a groove extending in a vertical direction or in a straight line. (Refer to...) Figure 13 (a) and Figure 13(b) The movable protrusion 221 can move up and down along the movable groove 241, thereby the switch 220 moves in a direction parallel to the direction in which the movable groove 241 extends.

[0150] Reference Figure 13 (a) Figure 13 (b) Figure 14 (a) Figure 14 (b) A spring 250 may be provided between the fixing part 240 and the switch 220. One side of the spring 250 may contact the fixing part 240, and the other side of the spring 250 may contact the switch 220. The spring 250 may apply an elastic restoring force to the switch 220.

[0151] Reference Figure 14 (a) and Figure 14 (b) The sliding part 230 may be provided with a sliding groove 231 extending obliquely relative to the moving groove 241. The sliding groove 231 is a groove provided on the side of the sliding part 230, and the sliding groove 231 may be provided on both sides of the sliding part 230.

[0152] Reference Figure 12 (a) and Figure 12 (b) The movable protrusion 221 of the switch 220 can be simultaneously inserted into the sliding groove 231 and the moving groove 241. Specifically, the movable protrusion 221 is inserted into the moving groove 241, and the switch 220 is inserted into the interior of the fixing part 240. Thereafter, the movable protrusion 221 is inserted into the sliding groove 231, and the sliding part 230 is inserted into the outside of the fixing part 240.

[0153] The fixing part 240 can be inserted into the housing 210 and fixedly connected to the housing 210, and can allow the switch 220 and the sliding part 230 to move relative to the housing 210.

[0154] When the movable protrusion 221 of the switch 220 is simultaneously inserted into the sliding groove 231 and the moving groove 241, the sliding part 230 slides and moves by the operation of the switch 220.

[0155] Specifically, such as Figure 12 As shown in (a), when the sliding part 230 does not protrude outward from the housing 210, pressing the switch 220 will move the switch 220 to the moving slot 241 and move upward.

[0156] At this time, since the sliding groove 231 extends obliquely relative to the moving groove 241, the moving protrusion 221 inserted into the sliding groove 231 pushes the sliding part 230 to the outside of the housing 210 and causes it to slide, as shown. Figure 12 As shown in (b).

[0157] Among them, such as Figure 12 As shown in (a), when the sliding part 230 does not protrude outward from the housing 210, pressing the switch 220 causes the moving protrusion 221 of the switch 220 to stop above the moving groove 241 via the path guide part 260 (described later). Figure 12 As shown in (b).

[0158] like Figure 12 As shown in (b), when the sliding part 230 protrudes outward from the housing 210, pressing the switch 220 again causes the moving protrusion 221 of the switch 220 to move downward along the moving groove 241 by the force of the spring 250. Figure 12 As shown in (a), the sliding part 230 is in a state where it does not protrude to the outside of the housing 210.

[0159] According to an embodiment of the present invention, the sliding part 230 may be provided with an extension groove 232 extending in one direction. The extension groove 232 is disposed above the sliding groove 231. When the moving protrusion 221 of the switch 220 is stopped at a point above the moving groove 241 via the path guide part 260 (described later), the extension groove 232 may be a groove for arranging the moving protrusion 221.

[0160] According to an embodiment of the present invention, the shelf fixing device 200 may include a path guide portion 260, which is formed in the shape of a strip and attached to the fixing portion 240, and contacts one side 222 of the switch 220.

[0161] Reference Figure 15 (a) and Figure 15 (b) The path guide 260 is composed of strips and is fixedly attached to the fixing part 240. By operating the switch 220, the path guide 260 can move along one side 222 of the switch 220.

[0162] Specifically, one side of the path guide 260 can be fixedly connected to the fixing part 240, and the other side of the path guide 260 can contact one side 222 of the switch 220.

[0163] According to an embodiment of the present invention, when the movable protrusion 221 of the switch 220 remains stationary above the movable groove 241, the sliding portion 230 remains protruding outward from the housing 210. Furthermore, when the movable protrusion 221 of the switch 220 is positioned below the movable groove 241, the sliding portion 230 may not protrude outward from the housing 210.

[0164] The path guide 260 can be a component for adjusting the movement of the switch 220, so that the moving protrusion 221 of the switch 220 remains stationary above the moving groove 241.

[0165] When the path guide 260 moves downward, a first path 223 may be provided on one side 222 of the switch 220, contacting one side of the switch 220. And when the path guide 260 moves upward, a second path 224 may be provided on one side of the switch 220, contacting one side 222 of the switch 220.

[0166] The first path 223 and the second path 224 can be points on one side 222 of the switch 220 that contact the path guide 260. When the switch 220 moves upward along the moving groove 241, the path guide 260 moves downward along the first path 223; when the switch 220 moves downward along the moving groove 241, the path guide 260 moves upward along the second path 224.

[0167] Reference Figure 16 (a) and Figure 16 (b) A first path guide protrusion 270, a second path guide protrusion 280, and a third path guide protrusion 290 may be provided on one side 222 of the switch 220, protruding outward from one side 222 of the switch 220.

[0168] Reference Figure 16 (a) and Figure 16 (b) The first path guide protrusion 270 is disposed inside one side 222 of the switch 220. Specifically, the first path guide protrusion 270 may be disposed at the center of one side 222 of the switch 220.

[0169] Above the first path guide protrusion 270, there may be a first upward downward tilt 271 and a second upward downward tilt 272. The first upward downward tilt 271 tilts downward from the central axis 225 of one side 222 of the switch 220 toward the first path 223, and the second upward downward tilt 272 tilts downward from the central axis 225 of one side 222 of the switch 220 toward the second path 224.

[0170] Reference Figure 16 (a) and Figure 16 (b) A first downward slope 273 and a second downward slope 274 may be provided below the first path guide protrusion 270. The first downward slope 273 slopes downward from the central axis 225 of one side 222 of the switch 220 toward the first path 223, and the second downward slope 274 slopes downward from the central axis 225 of one side 222 of the switch 220 toward the second path 224.

[0171] The upper part of one side 222 of the switch 220 refers to Figure 16 (a) and Figure 16 (b) The direction in which the movable protrusion 221 is set, the lower part of one side 222 of the switch 220 refers to Figure 16 (a) and Figure 16 (b) is set in the opposite direction of the movable protrusion 221.

[0172] Reference Figure 16 (a) and Figure 16 (b) The second path guide protrusion 280 is disposed below the first path 223. The second path guide protrusion 280 may be inclined upward 281 from the central axis 225 of one side 222 of the switch 220 toward the first path 223.

[0173] Reference Figure 16 (a) and Figure 16 (b) The third path guide protrusion 290 is disposed below the second downward slope 274. The third path guide protrusion 290 may form a downward slope 291 from the central axis 225 of one side 222 of the switch 220 toward the second path 224.

[0174] Reference Figure 15 (a) and Figure 16 (b) When the sliding part 230 does not protrude outside the housing 210, the path guide part 260 can be configured in the initial position.

[0175] When the switch 220 is pressed, the path guide 260 moves along the first path 223, and the moving protrusion 221 of the switch 220 can remain stationary above the moving slot 241.

[0176] Specifically, when the switch 220 is pressed while the sliding part 230 is not protruding outside the housing 210, the switch 220 moves upward and the path guide part 260 moves downward along one side 222 of the switch 220.

[0177] When the path guide 260 moves downward along one side 222 of the switch 220, the path guide 260 moves downward along the first path guide protrusion 270 at a downward tilt 271 toward the first path 223.

[0178] When the path guide 260 moves along the first path 223, the path guide 260 contacts the upward tilt 281 of the second path guide protrusion 280 disposed below the first path 223, and is disposed below the first downward tilt 273 and the second downward tilt 274 of the first path guide protrusion 270.

[0179] When the force applied to the switch 220 is removed, the switch 220 is pushed outward by the force of the spring 250. At this time, the switch 220 moves downward and the path guide 260 moves upward, causing the path guide 260 to be engaged between the first downward tilt 273 and the second downward tilt 274 of the first path guide protrusion 270.

[0180] When the path guide portion 260 is engaged between the first downward tilt 273 and the second downward tilt 274 of the first path guide protrusion 270, the movable protrusion 221 of the switch 220 can remain stationary at the point above the movable groove 241. When the movable protrusion 221 of the switch 220 remains stationary at the point above the movable groove 241, the sliding portion 230 can protrude outside the housing 210.

[0181] Reference Figure 15 (b) and Figure 16 (b) When the sliding part 230 is protruding outward from the housing 210, the switch 220 is pressed again, and the path guide part 260 moves along the second path 224.

[0182] Specifically, when the sliding part 230 is protruding outward from the housing 210, pressing the switch 220 again causes the switch 220 to move upward, and the path guide part 260 moves downward along one side 222 of the switch 220.

[0183] When the path guide 260 moves downward along one side 222 of the switch 220, the path guide 260 contacts the downward tilt 291 of the third path guide protrusion 290 and moves away from the first downward tilt 273 and the second downward tilt 274 of the first path guide protrusion 270, and moves to the second path 224.

[0184] When the force pressing the switch 220 is removed, the switch 220 moves downward by the force of the spring 250, and the path guide 260 moves upward.

[0185] At this time, the path guide 260 disengages from the first downward tilt 273 and the second downward tilt 274 of the first path guide protrusion 270 and moves to the second path 224, so the path guide 260 moves upward along the second path 224.

[0186] The path guide 260, which moves upward along the second path 224, can contact the second downward tilt 272 of the first path guide protrusion 270, so that the path guide 260 returns to the initial position in which the sliding part 230 does not protrude to the outside of the housing 210.

[0187] As described above, when the switch 220 is pressed once, the moving protrusion 221 of the switch 220 can remain stationary above the moving slot 241 via the path guide 260. Furthermore, when the switch 220 is pressed again, the moving protrusion 221 of the switch 220 can be repositioned below the moving slot 241.

[0188] According to an embodiment of the present invention, when the movable protrusion 221 of the switch 220 remains stationary above the movable groove 241, the sliding portion 230 can remain protruding outward from the housing 210. Furthermore, when the movable protrusion 221 of the switch 220 is positioned below the movable groove 241, the sliding portion 230 can remain in a state where it does not protrude outward from the housing 210.

[0189] Thus, according to the present invention, the system furniture equipped with a shelf fixing device can slide the sliding part 230 outward from the housing 210 or not, through the operation of the path guide part 260 and the switch 220.

[0190] According to an embodiment of the present invention, a chamfered portion 233 may be provided on one side of the sliding portion 230 protruding outward from the housing 210. The chamfered portion 233 may be a portion of the sliding portion 230 that has been chamfered.

[0191] When one side of the sliding part 230 is chamfered, the friction between the sliding part 230 and the fixed part 240 is reduced, thereby allowing the sliding part 230 to slide smoothly.

[0192] Reference Figure 3 and Figure 4 In the support portion 140 according to the embodiment of the present invention, a wing portion 143 protruding outward from the support portion 140 may be provided. A block 190 composed of a hexahedral shape may be incorporated into the wing portion 143. The wing portion 143 may be a protrusion protruding outward from the support portion 140, and the block 190 may be fixedly incorporated into the wing portion 143.

[0193] According to an embodiment of the present invention, the system furniture equipped with a shelf fixing device may further include a back panel 191 disposed between the two support columns 140. The back panel 191 may be a board composed of a plate and installed between the two support columns 140.

[0194] The back plate 191 can be installed via the block 190. Specifically, the back plate 191 is attached to the block 190 by fixing the contact point between the back plate 191 and the block 190 with a pin or a tacker. By fixing the back plate 191 to the block 190, the back plate 191 can be easily installed between the two support sections 140.

[0195] The system furniture with shelf fixing device according to the present utility model embodiment can be a built-in cabinet. If the system furniture with shelf fixing device according to the present utility model embodiment is a built-in cabinet, the system furniture can be installed on the wall through the block 190.

[0196] Specifically, the base plate 110 and the support column 140 are joined together via the connecting bracket 120, and the block 190 is fixed to the wall. Subsequently, the back plate 191 is attached to the block 190 using pins or a tacker, thus installing the system furniture onto the wall.

[0197] The advantage of the system furniture with shelf fixing device according to the present invention is that the system furniture is fixed to the wall by the block 190, so the system furniture composed of built-in cabinets can be easily installed on the wall. Furthermore, when disassembling the system furniture with shelf fixing device according to the present invention, the block 190 can be removed from the wall, and the system furniture can be easily detached from the wall.

[0198] Therefore, the advantage of the system furniture with shelf fixing device according to the present utility model embodiment is that when the system furniture is installed and disassembled to the wall by the block 190, it is easy to install, disassemble, and reconstruct the system furniture composed of embedded cabinets.

[0199] According to the embodiment of the present utility model, the shelf fixing device 200 used in the system furniture is provided in the connecting part 161 of the system furniture having a shelf 160 having a plurality of connecting parts 161 having hooks 162 and a base part 163 disposed between two of the connecting parts 161.

[0200] The base portion 163 is provided with an insertion space 165 for inserting the shelf fixing device 200 and a locking member 164 provided below the insertion space 165. The shelf fixing device 200 for system furniture according to an embodiment of the present invention includes: a housing 210 having an internal space and being connected to the connecting portion 161, a switch 220 provided in the housing 210, and a sliding portion 230 protruding outward from the housing 210 by operation of the switch 220. When the sliding portion 230 protrudes outward from the housing 210 by operation of the switch 220, the sliding portion 230 can be positioned above the locking protrusion 210.

[0201] The shelf fixing device 200 used in the system furniture of this utility model embodiment is the same as the shelf fixing device 200 included in the system furniture with shelf fixing device according to the above-described embodiment of this utility model, therefore, detailed description is omitted.

[0202] The system furniture with shelf fixing device according to the above-described embodiment of the present utility model has the following effects.

[0208] Therefore, the present invention has been described with reference to the embodiments shown in the accompanying drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and variations can be made to the embodiments therefrom. Thus, the true scope of protection of the present invention should be determined by the technical concept of the appended claims. Detailed Implementation

[0210] On the one hand, embodiments according to other aspects of the present invention are proposed. In the second and third embodiments presented below, descriptions of configurations that are the same or similar to those of the foregoing preferred embodiments are applied with the same or appropriate modifications, and repeated descriptions are omitted.

[0211] The second embodiment relates to a Nippon Furniture system equipped with a rod connecting device, which allows for adjustment of the height of the hanging brackets while permitting electrical connection, facilitates easy installation and disassembly of the hanging brackets, and allows for the continuous installation of multiple hanging brackets at the same height. Referring below... Figures 1 to 4 and Figures 18 to 23 The preferred embodiments of this utility model are described in detail below.

[0212] According to an embodiment of the present invention, a system furniture with a rod connecting device includes a base plate 110, a support column 140, a first rod assembly 360, a second rod assembly 370, and a rod connecting device 400.

[0213] Reference Figure 17 and Figure 2 The base plate 110 is composed of plates and can be the lower plate of a system furniture. Multiple base plates 110 can be provided, and the base plates 110 can be installed on the ground.

[0214] Figures 2 to 4 The description applies to the description of the foregoing preferred embodiment.

[0215] Reference Figure 18 The first rod assembly 360 and the second rod assembly 370 are coupled to the support column 140, and the first rod assembly 360 and the second rod assembly 370 may be coupled to the hanger of the system furniture.

[0216] The first rod assembly 360 includes: a first rod 361, which is rod-shaped, and a first connecting part 362, which is disposed on one side of the first rod 361 and has a plurality of hooks 380 formed in the shape of hooks to be inserted into the connecting hole 142 of the track 141.

[0217] The second rod assembly 370 includes: a second rod 371, which is rod-shaped, and a second connecting part 372, which is provided on one side of the second rod 371 and has a plurality of hooks 380 formed in the shape of hooks to be inserted into the connecting hole 142 of the track 141.

[0218] The first rod 361 and the second rod 371 can be rods for hanging clothes, clothes, etc. The first connecting part 362 and the second connecting part 372 can be connected to the shown support part 140 to install the first rod 361 and the second rod 371.

[0219] The first connecting portion 362 and the second connecting portion 372 may be composed of cantilever arms, and one side of the first connecting portion 362 and the second connecting portion 372 may be provided with a plurality of hook portions 380 formed in a hook shape.

[0220] Reference Figure 3 and Figure 19 By inserting the hook portion 380, which is formed in a hook shape, into the connecting hole 142, the first connecting portion 362 and the second connecting portion 372 can be connected to the support portion 140. The hook portion 380 can be connected to any one or more of the plurality of connecting holes 142.

[0221] According to an embodiment of this utility model, the height at which the first connecting part 362 and the second connecting part 372 are attached to the support part 140 is adjusted by changing the position of the hook part 380 attached to the plurality of connecting holes 142. Thus, the height at which the first rod assembly 360 and the second rod assembly 370 are attached to the support part 140 can be adjusted.

[0222] The furniture system with a rod connecting device according to an embodiment of the present invention may further include a third electrode 381. The third electrode 381 is disposed on the first connecting portion 362 and the second connecting portion 372, and when the first connecting portion 362 and the second connecting portion 372 are connected to the support portion 140, it contacts the second electrode 150. The third electrode 381 includes a cathode and an anode, and is composed of a pair of electrodes.

[0223] When the first connecting portion 362 and the second connecting portion 372 are connected to the support portion 140, the cathode of the third electrode 381 can contact the cathode of the second electrode 150, and the anode of the third electrode 381 can contact the anode of the second electrode 150. Thus, the second electrode 150 and the third electrode 381 can be electrically connected.

[0224] As described above, the second electrode 150 is composed of a thin film and extends along the height direction of the support portion 140. Therefore, even if the first rod assembly 360 and the second rod assembly 370 are attached to the support portion 140 at any height, the second electrode 150 can contact and electrically connect with the third electrode 381.

[0225] According to an embodiment of the present invention, the third electrode 381 may be disposed in the first connecting portion 362 and the second connecting portion 372, and the third electrode 381 may be disposed in the hook portion 380 of the first connecting portion 362 and the second connecting portion.

[0226] The third electrode 381 may include a third electrode connection portion 382 that is bent and protrudes outward from the hook portion 380. (See reference...) Figure 7 The third electrode connection portion 382 can be bent and protrude outward from the hook portion 380.

[0227] As described above, the second electrode 150 can be disposed inside the support portion 140 and can be composed of a thin film extending along the height direction of the support portion 140. When the hook portion 380 is inserted into the connecting hole 142 of the track 141, the third electrode connecting portion 382 protruding from the hook portion 380 contacts the second electrode 150, and the third electrode 381 and the second electrode 150 can be electrically connected.

[0228] The third electrode connection portion 382 may include a cathode and an anode. When the second electrode 150, which is composed of a thin film, contacts the third electrode connection portion 382, ​​the cathode of the second electrode 150 may contact the cathode of the third electrode connection portion 382, ​​and the anode of the second electrode 150 may contact the anode of the third electrode connection portion 382.

[0229] Thus, according to the present invention, the furniture system equipped with the rod connection device can electrically connect the second electrode 150 and the third electrode 381 by simply combining or assembling the hook portion 380 of the first connecting portion 362 and the second connecting portion 372 to the support portion 140.

[0230] Reference Figure 4 and Figure 20 Since the second electrode 150 according to this embodiment of the present invention is composed of a thin film extending along the height direction of the support portion 140, the third electrode 381 and the second electrode 150 can be contacted and electrically connected even if the hook portion 380 is attached to any height of the support portion 140.

[0231] That is, even if the hook 380 is inserted into any of the plurality of engagement holes 142 for engagement, the second electrode 150 and the third electrode 381 can contact and be electrically connected. Thus, even if the installation height of the first rod assembly 360 and the second rod assembly 370 relative to the support portion 140 is adjusted, the second electrode 150 and the third electrode 381 will contact and be electrically connected.

[0232] According to an embodiment of the present invention, the third electrode connection portion 382 may be composed of an elastic component, and the third electrode connection portion 382 may be in an open state to the outside before the hook portion 380 is inserted into the connecting hole 142.

[0233] Reference Figure 20 When the hook portion 380 is inserted into the connecting hole 142, the outwardly open third electrode connection portion 382 can be gathered inward through the support portion 140. That is, the hook portion 380 can gather the outwardly open third electrode connection portion 382 inward and be pressed into the inside of the support portion 140 through the connecting hole 142.

[0234] When the third electrode connection portion 382 converges inward through the support portion 140, an elastic restoring force occurs in the third electrode connection portion 382, ​​which is composed of an elastic member. When the hook portion 380 is inserted into the connecting hole 142, the third electrode connection portion 382 is elastically compressed to open outward by the elastic restoring force.

[0235] Thus, when the hook portion 380 is inserted into the connecting hole 142, the third electrode connection portion 382 is elastically compressed to open outward, firmly contacting the second electrode 150.

[0236] According to an embodiment of the present invention, a furniture system equipped with a rod connection device may include lighting 392 provided on any one or more of the first rod 361 and the second rod 371.

[0237] The illumination 392 is electrically connected to the third electrode 381, and the illumination 392 can be disposed at various points on the first rod 361 and the second rod 371. The illumination 392 can be connected to the third electrode 381 via wires or other electrical connection devices, and the illumination 392 can be composed of a diffuser plate. However, it is not limited to this, and the illumination 392 can be disposed on the first rod 361 and the second rod 371 in various forms.

[0238] The first electrode 130, located on the connecting bracket 120, receives power through the electrical connection line 121, and the power supplied to the first electrode 130 is transferred to the second electrode 150. The power transferred to the second electrode 150 is transferred to the third electrode 381, and the power transferred to the third electrode 381 is transferred to the illumination 392, from which light can be emitted.

[0239] According to an embodiment of the present invention, the first rod assembly 360 may have the first connecting portion 362 on both one side and the other side, or the first connecting portion 362 may be provided only on one side of the first rod assembly 360.

[0240] According to an embodiment of the present invention, the second rod assembly 370 may have the second connecting portion 372 on only one side, and may be opened on the other side of the second rod connecting portion 372 without the second connecting portion 372 being provided.

[0241] When the first rod assembly 360 and the second rod assembly 370 are joined to the support column 140, the connecting part 372 is provided on one side and the other side of the second rod assembly 370, so the first rod assembly 360 and the second rod assembly 370 cannot be continuously installed at the same height.

[0242] Specifically, when the first rod assembly 360 and the second rod assembly 370 are continuously installed at the same height in the system furniture, and the second rod assembly 370 is provided with the second connecting part 372 on both one side and the other side, interference will occur between the first connecting part 362 provided on one side of the first rod assembly 360 and the second connecting part 372 provided on the other side of the second rod assembly 370.

[0243] More specifically, only one of the first connecting part 362 provided on one side of the first rod assembly 360 and the second connecting part 372 provided on the other side of the second rod assembly 370 can be inserted into the track 141 provided in the support part 140. Therefore, since the second rod assembly 370 is provided on both one side and the other side, it is not possible to continuously install the first rod assembly 360 and the second rod assembly 370 at the same height.

[0244] Of course, multiple tracks 141 are installed on the support column 140, and the first connecting portion 362 located on one side of the first rod assembly 360 and the second connecting portion 372 located on the other side of the second rod assembly 370 can be respectively connected to the tracks 141. However, when multiple tracks 141 are installed on the support column 140 in this way, the size of the system furniture increases, and it is also aesthetically unappealing.

[0245] To address this issue, the system furniture according to this utility model embodiment, which includes a rod connecting device, can utilize a rod connecting device 400. The rod connecting device 400 connects the first connecting portion 362 of the first rod assembly 360 and the other side of the second rod 371 of the second rod assembly 370.

[0246] The rod connecting device 400 includes a first connecting component 410 and a second connecting component 420. (Refer to...) Figure 19 and Figure 20 A connecting component 363 may be provided on one side of the first connecting portion 362 of the first rod assembly 360, and the connecting component 363 is provided with a connecting groove 364 extending along the length direction.

[0247] The connecting member 363 is attached to the side of the first connecting portion 362, and the connecting member 363 has a connecting groove 364 formed therein. The connecting groove 364 is a groove extending along the length direction or in one direction, and the connecting protrusion 411 described later can be inserted into the connecting groove 364.

[0248] According to an embodiment of the present invention, the connecting component 363 is composed of a component separate from the first connecting portion 362 and can be connected to the side of the first connecting portion 362, and the connecting component 363 can be integrally formed with the first connecting portion 362.

[0249] The first connecting member 410 extends along its length and is provided with a connecting protrusion 411 that is inserted into the connecting groove 364. The connecting protrusion 411 is a protrusion that extends along its length or in one direction, and the connecting protrusion 411 can protrude outward from the first connecting member 410.

[0250] The connecting protrusion 411 may be formed in a shape corresponding to the shape of the connecting groove 364 so as to be inserted into the connecting groove 364. According to an embodiment of the present invention, when the connecting protrusion 411 is inserted into the connecting groove 364, the connecting protrusion 411 will not fall off the connecting groove 364 when the first connecting member 410 is rotated.

[0251] Specifically, refer to Figure 20 and Figure 21 A blank space is formed inside the connecting member 363. When the connecting protrusion 411 is inserted into the connecting groove 364 of the connecting member 363, the connecting protrusion 411 can rotate through the blank space inside the connecting member 363.

[0252] Since the connecting protrusion 411 is formed in a shape corresponding to the shape of the connecting groove 364 so as to be inserted into the connecting groove 364, when the connecting protrusion 411 is rotated, the connecting protrusion 411 is stuck on the outside of the connecting groove 364, so that the connecting protrusion 411 will not fall off the connecting groove 364.

[0253] The second connecting member 420 is attached to the other side of the second rod 371, and the first connecting member 410 is rotatably attached to the second connecting member 420.

[0254] Reference Figure 21 , Figure 22 (a) and Figure 22 (b) A circular through hole 421 may be provided inside the second connecting member 420. A rotating protrusion 415 corresponding to the shape of the through hole 421 may be provided inside the first connecting member 410 to be inserted into the through hole 421.

[0255] The interior of the rotating protrusion 415 may be provided with a first screw engagement hole 416 for inserting a screw 430, and the screw 430 may pass through the through hole 421 in one side of the second connecting member 420 and enter the first screw engagement hole 416.

[0256] With the rotating protrusion 415 of the first connecting member 410 inserted into the through hole 421 of the second connecting member 420, and the screw 430 engaged with the first screw engagement hole 416, the first connecting member 410 can be rotatably engaged with the second connecting member 420.

[0257] At this time, a bearing 431 may be provided between the screw 430 and the through hole 421. The bearing 431 is used to prevent the screw 430 from contacting and fixing to the second connecting member 420.

[0258] Without the bearing 431, the screw 430 can contact the second connecting member 420. When the screw 430 contacts the second connecting member 420, friction occurs between the screw 430 and the second connecting member 420 when the first connecting member 410 rotates, thus limiting the rotation of the first connecting member 410.

[0259] Since the screw 430 is engaged with the first screw engagement hole 416 of the first connecting member 410, the screw 430 rotates together with the first connecting member 410.

[0260] When the bearing 431 is provided between the screw 430 and the through hole 421, it prevents the screw 430 from contacting the second connecting member 420, and allows the first connecting member 410 to rotate smoothly relative to the second connecting member 420.

[0261] According to an embodiment of the present invention, the first connecting member 410 may be provided with a handle 414 protruding outward from the first connecting member 410. (See also...) Figure 22 (a) and Figure 22 (b) The handle 414 protrudes outward from the first connecting member 410, and force is applied to the first connecting member 410 through the handle 414, which can cause the first connecting member 410 to rotate relative to the second connecting member 420.

[0262] According to an embodiment of the present invention, one side of the second connecting member 420 may be provided with a rotation-limiting protrusion 423 extending along the circumferential direction of the second connecting member 420 and protruding outward. The rotation-limiting protrusion 423 may extend along the circumferential direction of the second connecting member 420 at a specified angle based on the center of the second connecting member 420.

[0263] The rotation-limiting protrusion 423 can limit the rotation of the first connecting member 410. (See reference...) Figure 22 (a) and Figure 22 (b) The handle 414 of the first connecting member 410 can protrude outward at the point where the rotation limiting protrusion 423 is not provided, and the handle 414 can only rotate at the point where the rotation limiting protrusion 423 is not provided.

[0264] Specifically, on one side of the second connecting member 420, there are points where the rotation limiting protrusion 423 is provided along the circumferential direction and points where the rotation limiting protrusion 423 is not provided. The handle 414 of the first connecting member 410 can protrude outward at the point where the rotation limiting protrusion 423 is not provided, and when the handle 414 is rotated, the handle 414 can contact the rotation limiting protrusion 423.

[0265] When the handle 414 contacts the rotation limiting protrusion 423, the rotation of the handle 414 can be limited by the rotation limiting protrusion 423. That is, the first connecting member 410 can rotate only at the point in the second connecting member 420 where the rotation limiting protrusion 423 is not provided, and the rotation angle of the first connecting member 410 can be limited by the rotation limiting protrusion 423.

[0266] The rod connecting device 400 according to the embodiment of the present utility model can be installed in the following manner.

[0267] See Figure 22 (a) and Figure 22 (b) The first connecting member 410 and the second connecting member 420 can be first connected by the screw 430 and the bearing 431. The second connecting member 420 can be connected to the other side of the second rod 371. If the second connecting member 420 is first connected to the other side of the second rod 371, one side of the second connecting member 420 can be blocked by the second rod 371.

[0268] The screw 430 must pass through the through hole 421 on one side of the second connecting member 420 and be engaged with the first connecting member 410. If the second connecting member 420 is engaged with the other side of the second rod 371 first, there will be no space for inserting the screw 430 due to the second rod 371. Therefore, preferably, the first connecting member 410 and the second connecting member 420 are engaged first by the screw 430 and the bearing 431.

[0269] After the first connecting member 410 and the second connecting member 420 are joined, the second connecting member 420 is joined to the other side of the second rod 371. The second connecting member 420 is provided with a second screw engagement hole 422 through which a screw passes, and the interior of the second rod 371 is provided with a screw engagement hole 373 into which a screw can be inserted.

[0270] If a screw is inserted into the screw engagement hole 373 of the second rod 371 from the other side of the second connecting member 420 through the second screw engagement hole 422, as Figure 23 As shown, with the first connecting member incorporated in the second connecting member 420, the second connecting member 420 is attached to the other side of the second rod 371.

[0271] Subsequently, the connecting protrusion 411 of the first connecting member 410 is inserted into the connecting groove 364. When the first connecting member 410 is rotated by the handle 414, the connecting protrusion 411 will not fall out of the connecting groove 364.

[0272] Since the connecting protrusion 411 does not fall off from the connecting groove 364, the first connecting portion 362 of the first rod assembly 360 and the other side of the second rod 371 can be connected.

[0273] Thus, in the furniture system with rod connecting device according to the present utility model embodiment, even if the second connecting part 372 is not provided on the other side of the second rod 371, the first rod assembly 360 and the second rod assembly 370 can be installed at the same height through the rod connecting device 400.

[0274] According to an embodiment of the present invention, the side of the first connecting member 410 may be provided with a side groove 417 that is recessed towards the outside of the first connecting member 410. As described above, after the first connecting member 410 and the second connecting member 420 are first joined together, the second connecting member 420 can be joined to the second rod 371.

[0275] Reference Figure 22 (a) Figure 22(b) Figure 23 Since the first connecting member 410 is disposed on the other side of the second connecting member 420, the second screw engagement hole 422 of the second connecting member 420 can be blocked by the first connecting member 410.

[0276] To prevent this, the side of the first connecting member 410 may be provided with a side groove 417 that is recessed outward from the side of the first connecting member 410. When the first connecting member 410 is engaged with the second connecting member 420, the side groove 417 may be a groove that exposes the second screw engagement hole 422 of the second connecting member 420 to the outside.

[0277] The first connecting member 410 has a side groove 417 on its side, which can prevent the second screw connection hole 422 from being blocked even if the first connecting member 410 is connected to the second connecting member 420, and the second connecting member 420 can be connected to the second rod 371 through the second screw connection hole 422.

[0278] The connecting groove 364 according to an embodiment of the present invention includes a circular groove 365 composed of circles and an extension groove 366 extending outward from the side of the circular groove 365. Furthermore, the connecting protrusion 411 according to an embodiment of the present invention includes a circular protrusion 412 inserted into the circular groove 365 and an extension protrusion 413 extending outward from the side of the circular protrusion 412 and inserted into the extension groove 366.

[0279] The circular groove 365 and the circular protrusion 412 are both circular in shape. When the circular protrusion 412 is inserted into the circular groove 365, the central axes of the circular groove 365 and the circular protrusion 412 can coincide. The circular protrusion 412 can be formed in a shape corresponding to the circular groove 365 so that it can be inserted into the circular groove 365.

[0280] The extension groove 366 extends outward from the side of the circular groove 365, and the extension protrusion 413 extends outward from the side of the circular protrusion 412. The extension protrusion 413 may be formed in a shape corresponding to the shape of the extension groove 366 so as to be inserted into the extension groove 366.

[0281] The circular protrusion 412 is inserted into the circular groove 365, and the extended protrusion 413 is inserted into the extended groove 366, so that the connecting protrusion 411 can be inserted into the connecting groove 364.

[0282] When the connecting protrusion 411 is inserted into the connecting groove 364 and the first connecting member 410 is rotated, the circular protrusion 412 remains inserted into the circular groove 365, and the extension protrusion 413 can be dislodged from the extension groove 366.

[0283] Since the circular groove 365 and the circular protrusion 412 are circular and coincide with each other's central axis, the first connecting member 410 can rotate based on the central axis of the circular groove 365 and the circular protrusion 412.

[0284] When the first connecting member 410 rotates based on the central axis of the circular groove 365 and the circular protrusion 412, the extension protrusion 413 disengages from the extension groove 366 and is locked inside the engagement groove 364. Therefore, the engagement protrusion 411 will not disengage from the engagement groove 364.

[0285] That is, according to the embodiment of the present invention, the connecting groove 364 and the connecting protrusion 411 can smoothly rotate the first connecting member 410 through the circular groove 365 and the circular protrusion 412 composed of circles, and when the first connecting member 410 rotates, the connecting protrusion 411 will not fall off from the connecting groove 364 through the extension protrusion 413 that falls off from the extension groove 411.

[0286] According to an embodiment of the present invention, one side of the second connecting portion 372 can also be connected to a third rod assembly via a rod connecting device 400. When the third rod assembly is connected to one side of the second connecting portion 372 via the rod connecting device 400, the second connecting portion 372 can be composed of the same structure as the first connecting portion 362, and the other side of the third rod can be composed of the same structure as the other side of the second rod 371.

[0287] According to an embodiment of the present invention, the furniture system equipped with a rod connecting device can also be connected to another rod assembly other than the third rod assembly via the rod connecting device 400. Thus, according to an embodiment of the present invention, the furniture system equipped with a rod connecting device can continuously install multiple rod assemblies at the same height via the rod connecting device 400.

[0288] According to the system furniture of the present utility model, the rod connecting device 400 used in the system furniture provides a first rod assembly 360 including a first rod 361 and a first connecting part 362, and a second assembly 370 including a second rod 371 and a second rod connecting part 372, to connect the first connecting part of the first rod assembly 360 and the other side of the second rod 371 of the second rod assembly 370.

[0289] A connecting member 363 is provided on one side of the first connecting portion 362 of the first rod assembly 360. The connecting member 363 is provided with a connecting groove 364 extending along the length direction. The rod connecting device 400 used in the system furniture according to the embodiment of the present utility model includes a first connecting member 410 having a connecting protrusion 411 extending along the length direction and inserted into the connecting groove 364, and a second connecting member connected to the other side of the second rod 371 of the second rod assembly 370 and the first connecting member 410 being rotatably connected. The connecting protrusion 411 is inserted into the connecting groove 364. When the first connecting member 410 is rotated, the connecting protrusion 411 will not disengage from the connecting groove 364.

[0290] The rod connecting device 400 used in the system furniture of this utility model embodiment is the same as the rod connecting device 400 included in the system furniture with rod connecting device according to the above-described embodiment of this utility model, therefore, detailed description is omitted.

[0291] The system furniture with a rod connecting device according to the above-described embodiment of the present invention has the following effects. Since it has the same or similar configuration and effects as the aforementioned preferred embodiment, repeated descriptions are omitted.

[0292] The furniture system with a rod connection device according to the present invention has the advantage that the connecting part of the rod assembly is selectively connected to a plurality of connecting holes provided in the track of the support column, and electrical connection is allowed by contacting the second electrode provided in the support column with the third electrode provided in the connecting part of the rod assembly, and the height of the hanger can be adjusted.

[0293] Furthermore, the system furniture with a rod connecting device according to the present utility model has the advantage that by connecting the first connecting part on one side of the first rod assembly to the other side of the second rod assembly through the rod connecting device, multiple rod assemblies can be continuously installed at the same height.

[0294] The system furniture with a rod connection device according to an embodiment of the present invention has the advantage that, without using wires, the first electrode and the second electrode are electrically connected by installing, combining and assembling the support column on the connecting bracket, and the second electrode and the third electrode are connected by installing, combining and assembling the first connecting part of the first rod assembly and the second connecting part of the second rod assembly to the support column.

[0295] The furniture system with a rod connecting device according to the present utility model has the advantage that the first connecting part of the first rod assembly and the second connecting part of the second rod assembly are selectively connected to a plurality of connecting holes provided in the track of the support column, and electrical connection is allowed by contacting the second electrode provided in the support column with the third electrode provided in the first connecting part and the second connecting part, and the height of the first rod assembly and the second rod assembly can be adjusted.

[0296] Meanwhile, the system furniture with a rod connection device according to the present utility model has the advantage of being easy to install and disassemble the hanger, electrically separating the base plate, the support column and the hanger, and energizing the system by contacting the first electrode on the base plate, the second electrode on the support column and the third electrode on the connecting part of the rod assembly, thereby making it easy to find the electrical short circuit point.

[0297] A third embodiment of this utility model relates to a system furniture with an electrode support device, which allows for adjustable shelf height, easy installation and disassembly of hangers, and permits electrical connection via the electrode support device without the use of electrical wires. Referring below... Figures 1 to 4 and Figures 18 to 23 The preferred embodiments of this utility model are described in detail below.

[0298] According to an embodiment of the present invention, the system furniture equipped with an electrode support device includes a base plate 110, a support column 140, a shelf 160, and an electrode support device 200.

[0299] Figures 1 to 5 The description applies to the description of the foregoing preferred embodiment.

[0300] Reference Figure 5 and Figure 24 The connecting portion 161 can be coupled to the support portion 140 by inserting the hook portion 162, which is formed in a hook shape, into the coupling hole 142. The hook portion 162 can be coupled to any one or more of the plurality of coupling holes 142.

[0301] According to an embodiment of this utility model, the height at which the connecting part 161 engages with the support part 140 is adjusted by changing the position of the hook part 162 engaging with the plurality of engaging holes 142. Thus, the height at which the shelf 160 engages with the support part 140 can be adjusted.

[0302] The base portion 163 of the shelf 160 is disposed between the two connecting portions 161. The base portion 163 may be plate-shaped and may be the base plate of the shelf 160.

[0303] Reference Figure 25 The electrode support device 600 is disposed on the connecting part 161. The electrode support device 600 may be a support for mounting the connecting electrode 630 on the connecting part 161.

[0304] The electrode support device 600 includes a housing 610, a base plate 620, a connecting electrode 630, and a spring pin 640.

[0305] Reference Figure 25 and Figure 26 The housing 610 is provided with a hook housing 611 protruding outward from the connecting part 161 and is attached to the connecting part 161 so as to be inserted into the connecting hole 142 of the track 141.

[0306] The housing 610 can be attached to the connecting part 161. When the housing 610 is attached to the connecting part 161, the portion protruding to the outside of the connecting part 161 can be the hook housing 611.

[0307] The hook housing 611 may be composed of a shape corresponding to the hook portion 162, and the hook housing 611 may be inserted into the engagement hole 142 of the track 141.

[0308] As described above, by inserting the hook portion 162 of the connecting portion 161 into the connecting hole 142, the connecting portion 161 can be connected to the support portion 140.

[0309] The hook housing 611 can replace any one of the plurality of hooks 162 provided in the connecting portion 161. According to an embodiment of the present invention, any one of the plurality of hooks 162 can be replaced by the hook housing 611, which is used to connect the connecting portion 161 to the support portion 140.

[0310] Reference Figure 26 and Figure 27 The hook housing 611 may be provided with a connecting electrode 630. The hook housing 611 may be provided with a pair of connecting electrodes 630, and the hook housing 611 may be provided with a connecting electrode 630 composed of an anode and a connecting electrode 630 composed of a cathode.

[0311] According to an embodiment of the present invention, the hook housing 611 may simultaneously provide a pair of connecting electrodes 630, consisting of a cathode and an anode. By providing a pair of connecting electrodes 630, consisting of a cathode and an anode, the electrode exposure points can be minimized, and the connecting electrodes 630 and the second electrode 150 can be electrically connected.

[0312] Specifically, when the connecting part 161 is attached to the support part 140, the hook housing 611 is inserted into the connecting hole 142 of the track 141, and the second electrode 150 can contact the connecting electrode 630. The connecting electrode 630 may include a cathode and an anode and may consist of a pair of electrodes, and the pair of connecting electrodes 630 may be disposed in one hook housing 611.

[0313] When the hook housing 611 is inserted into the engagement hole 142 of the track 141, the cathode of the connecting electrode 630 can contact the cathode of the second electrode 150, and the anode of the connecting electrode 630 can contact the anode of the second electrode 150. Thus, the second electrode 150 and the connecting electrode 630 can be electrically connected.

[0314] As described above, the second electrode 150 is composed of a thin film and extends along the height direction of the support portion 140. Therefore, even at any height at which the shelf 160 is attached to the support portion 140, it can contact and be electrically connected to the connection electrode 630 through the second electrode 150.

[0315] According to an embodiment of the present invention, the connecting electrode 630 may include a connecting electrode connecting portion 631 that is bent and protrudes outward from the hook housing 611. (See references...) Figure 28 The connecting electrode connection portion 631 can be bent and protrude outward from the hook portion 162.

[0316] When the hook housing 611 is inserted into the connecting hole 142 of the track 141, the connecting electrode connecting part 631 protruding from the hook housing 611 contacts the second electrode 150, and the connecting electrode 630 and the second electrode 150 can be electrically connected.

[0317] The connecting electrode connection portion 631 may include a cathode and an anode. When the second electrode 150, which is composed of a thin film, contacts the connecting electrode connection portion 631, the cathode of the second electrode 150 may contact the cathode of the connecting electrode connection portion 631, and the anode of the second electrode 150 may contact the anode of the connecting electrode connection portion 631.

[0318] Thus, according to the present invention, the system furniture equipped with an electrode support device can electrically connect the second electrode 150 and the connecting electrode 630 by simply combining or assembling the hook portion 162 and the hook housing 611 of the shelf 160 to the support portion 140.

[0319] Since the second electrode 150 according to this embodiment of the present invention is composed of a thin film extending along the height direction of the support portion 140, the connecting electrode 630 and the second electrode 150 can be contacted and electrically connected even if the hook housing 611 is attached to any height of the support portion 140.

[0320] That is, even if the hook portion 162 and the hook housing 611 are inserted into any of the plurality of engagement holes 142 for engagement, the second electrode 150 can contact and be electrically connected to the connecting electrode 630. Thus, even if the height of the shelf 160 relative to the support portion 140 is adjusted, the second electrode 150 and the connecting electrode 630 will contact and be electrically connected.

[0321] According to an embodiment of the present invention, the connecting electrode connection part 631 may be composed of an elastic component, and the connecting electrode connection part 631 may be in an open state before the hook housing 611 is inserted into the connecting hole 142.

[0322] When the hook housing 611 is inserted into the connecting hole 142, the outwardly open connecting electrode connection portion 631 can be gathered inward through the support portion 140. That is, the hook housing 611 can gather the outwardly open connecting electrode connection portion 631 inward and press the connecting electrode connection portion 631 into the inside of the support portion 140 through the connecting hole 142.

[0323] When the connecting electrode connection portion 631 converges inward through the support portion 140, an elastic restoring force occurs in the connecting electrode connection portion 631, which is composed of an elastic member. When the hook housing 611 is inserted into the connecting hole 142, the connecting electrode connection portion 631 is elastically compressed to open outward by the elastic restoring force.

[0324] Thus, when the hook housing 611 is inserted into the connecting hole 142, the connecting electrode connection portion 631 is elastically compressed to open outward, firmly contacting the connecting electrode connection portion 631 with the second electrode 150.

[0325] Reference Figure 26 and Figure 28 The substrate 620 is disposed inside the housing 610, and the connecting electrode 630 can be connected to one side of the substrate 620. The substrate 620 has a circuit inside, and the spring pin 640 can be disposed on the other side of the substrate 620.

[0326] The spring pin 640 protrudes outward from the housing 610 and is disposed on the other side of the base plate 620. The spring pin may consist of a pair of spring pins 640 protruding to the outside of the housing 610.

[0327] According to an embodiment of the present invention, the connecting electrode 630 and the spring pin 640 can be electrically connected via the substrate 620. Specifically, the connecting electrode 630 and the spring pin 640 can be electrically connected via a circuit disposed on the substrate 620.

[0328] The electrode support device 600 may include a pair of connecting electrodes 630 and spring pins 640. The connecting electrode 630, which is composed of an anode, is connected to one of the spring pins 640 through the substrate 620, and the connecting electrode 630, which is composed of a cathode, is connected to the other spring pin 640 through the substrate 620.

[0329] Reference Figure 29 According to an embodiment of the present invention, the electrode support device 600 connects the connecting electrode 630 and the spring pin 640 through the substrate 620, allowing electrical connection between the connecting electrode 630 and the spring pin 640 without the use of wires.

[0330] Using a wire to connect the connecting electrode 630 and the spring pin 640 poses a risk of the wire breaking inside the connecting portion 161. If a short circuit occurs due to the wire breaking inside the connecting portion 161, it becomes difficult to locate the short circuit point and repair the short circuit.

[0331] The electrode support device 600 according to an embodiment of the present invention has the advantage that the connecting electrode 630 and the spring pin 640 can be connected by the substrate 620 without the use of wires, thereby preventing the occurrence of short circuits and making it easy to find the point of electrical short circuit.

[0332] Reference Figure 30 The spring pin 640 can contact a contact terminal 564 disposed on the side of the base portion 163 of the shelf 160. The contact terminal 564 contacts the spring pin 640 and is electrically connected. When the spring pin 640 and the contact terminal 564 are connected, the power supplied through the connecting electrode 630 moves to the contact terminal 564.

[0333] The contact terminal 564 can be connected to various electrical devices, such as lighting 180 installed inside the shelf 160, and power can be supplied to various electrical devices installed inside the shelf 160 through the contact terminal 564.

[0334] According to an embodiment of the present invention, a system furniture equipped with an electrode support device may include a light fixture 180 disposed on the shelf 160 and connected to the connecting electrode 630. The light fixture 180 is electrically connected to the connecting electrode 630, and the light fixture 180 may be disposed at various points on the shelf 160.

[0335] The lighting 180 is electrically connected to the contact terminal 564, and the lighting 180 can be electrically connected to the connecting electrode 630 via the spring pin 640. The lighting 180 may be in the form of a diffuser plate. However, it is not limited to this, and the lighting 180 may be arranged on the shelf 160 in various forms.

[0336] The first electrode 130, disposed on the connecting bracket 120, receives power through the electrical connection line 121, and the power supplied to the first electrode 130 is transferred to the second electrode 150. The power transferred to the second electrode 150 is transferred to the connecting electrode 630, and the power transferred to the connecting electrode 630 is transferred to the contact terminal 564 through the substrate 620 and the spring pin 640. The power supplied to the contact terminal 564 is transferred to the illumination 180, thereby allowing light to be emitted from the illumination 180.

[0337] Reference Figure 29 and Figure 31 According to an embodiment of the present invention, the electrode support device 600 is disposed inside the hook housing 611 and includes a first support portion 650 and a second support portion 660 supporting a connecting electrode connection portion 631.

[0338] As described above, the connecting electrode connection portion 631 protrudes from the outside of the hook housing 611, and the connecting electrode connection portion 631 can be in an open state before the hook housing 611 is inserted into the connecting hole 142.

[0339] The hook housing 611 can gather the outwardly open connecting electrode connection part 631 to the inside and press the connecting electrode connection part 631 into the connecting hole 142, so that the connecting electrode connection part 631 and the second electrode 150 are in firm contact.

[0340] According to an embodiment of the present invention, since the connecting electrode connection portion 631 is composed of an elastic component, when the hook housing 611 is separated in the connecting hole 142, the connecting electrode connection portion 631 will return to the shape of the hook housing 611 protruding outward.

[0341] However, if the connecting electrode connection portion 631 is reused repeatedly, or if the connecting electrode connection portion 631 is pressed into the connection hole 142 for an extended period of time, there is a risk that elastic deformation may occur in the connecting electrode connection portion 631.

[0342] When elastic deformation occurs in the connecting electrode connection portion 631, even if the hook housing 611 is separated in the connecting hole 142, the connecting electrode connection portion 631 will not return to its outward protruding shape. Therefore, when the connection portion 161 is reused, there is a risk that the connecting electrode connection portion 631 and the second electrode 150 may not make secure contact.

[0343] The first support portion 650 and the second support portion 660 may be components used to prevent this situation. (See reference...) Figure 31 The first support portion 650 includes a first upwardly inclined portion 651 that is formed in the direction of the substrate 620 toward the hook housing 611, and a first downwardly inclined portion 652 that is formed in the direction of the substrate 620 toward the hook housing 611.

[0344] Reference Figure 29 One of the pair of connecting electrode connection portions 631 includes an upwardly inclined and a downwardly inclined point where the upwardly inclined and downwardly inclined points intersect and can protrude outward from the hook housing 611.

[0345] The first support portion 650 may be composed of a shape corresponding to the shape of the connecting electrode connection portion 631. (Refer to...) Figure 29 The first upward tilting portion 651 of the first support portion 650 supports the upward tilt of the connecting electrode connection portion 631, and the first downward tilting portion 652 of the first support portion 650 supports the downward tilt of the connecting electrode connection portion 631.

[0346] According to an embodiment of the present invention, since the connecting electrode connection part 631 is supported by the first support part 650, even if elastic deformation occurs in the connecting electrode connection part 631, the connecting electrode connection part 631 can still protrude to the outside of the hook housing 611.

[0347] Specifically, the first support portion 650 may be composed of a shape corresponding to one of the connecting electrode connection portions 631, so that even if elastic deformation occurs in the connecting electrode connection portion 631, the connecting electrode connection portion 631 protrudes outward from the hook housing 611 according to the shape of the first support portion 650.

[0348] Therefore, when the hook housing 611 is separated in the connecting hole 142, the connecting electrode connection portion 631 can be restored to the shape of the hook housing 611 protruding outward.

[0349] Reference Figure 31 The second support portion 660 includes a second downwardly inclined portion 661 formed in the direction from the base plate 620 toward the hook housing 611. (See reference...) Figure 29 One of the pair of connecting electrode connection portions 631 includes a point where the downward tilting and downward tilting meet, which can protrude outward from the hook housing 611.

[0350] The second support portion 660 may be composed of a shape corresponding to the downward inclination of the connecting electrode connection portion 631, as shown in the figure. Figure 29 The second downward tilting portion 661 of the second support portion 660 supports the downward tilt of the connecting electrode connection portion 631.

[0351] According to an embodiment of the present invention, since the connecting electrode connection part 631 is supported by the second support part 660, even if elastic deformation occurs in the connecting electrode connection part 631, the connecting electrode connection part 631 can still protrude to the outside of the hook housing 611.

[0352] Specifically, the second support portion 660 may be composed of a shape corresponding to the connecting electrode connection portion 631, so that even if elastic deformation occurs in the connecting electrode connection portion 631, the connecting electrode connection portion 631 protrudes outward from the hook housing 611 according to the shape of the second support portion 660.

[0353] Therefore, when the hook housing 611 is separated in the connecting hole 142, the connecting electrode connection portion 631 can be restored to the shape of the hook housing 611 protruding outward.

[0354] Reference Figure 28 and Figure 29 The first support portion 650 and the second support portion 660 are disposed in the housing 610 and fixedly installed to the connecting housing 612 which is connected to the housing 610.

[0355] At this time, the first support portion 650 and the second support portion 660 can be disposed inside the hook housing 611 protruding outward from the connecting portion 161, and can be fixedly connected to the housing 610 by the connecting housing 612.

[0356] According to an embodiment of the present invention, the first support portion 650 and the second support portion 660 may be composed of a single component. (See also...) Figure 31 The first support portion 650 and the second support portion 660 may be composed of a single component, and the first support portion 650 may be disposed on one side of the component, while the second support portion 660 may be disposed on the other side of the component.

[0357] However, it is not limited to this. The first support 650 and the second support 660 may be composed of separate components and may also be installed separately in the connecting housing 612.

[0358] The electrode support device 600 used in the system furniture according to an embodiment of the present invention is provided with a hook housing 611 protruding outward from the connecting portion 161 to be inserted into the connecting hole 142 of the track 141, and includes: a housing 610, which is connected to the connecting portion; a base plate 620, which is disposed inside the housing 610; a connecting electrode 630, which is disposed in the hook housing 611 and connected to one side of the base plate 620; and a spring pin 640, which protrudes outward from the housing 610 and is connected to the other side of the base plate 620.

[0359] The electrode support device 600 used in the system furniture of this utility model embodiment is the same as the electrode support device 600 included in the system furniture with electrode support device according to the above-described embodiment of this utility model, therefore, detailed description is omitted.

[0360] The system furniture with electrode support device according to the above-described embodiment of the present invention has the following effects. Since it has the same or similar configuration and effects as the foregoing preferred embodiment, repeated descriptions are omitted.

[0361] The system furniture with an electrode support device according to an embodiment of the present invention has the advantage that, by providing a base plate and mounting the connecting electrodes to the connecting part of the electrode support device, electrical connection can be allowed without the use of wires.

[0362] According to an embodiment of the present invention, the system furniture with an electrode support device has the advantage that a pair of connecting electrodes are installed in a hook housing in the insertion hole of the track, thereby minimizing the electrode exposure point and electrically connecting the connecting electrode to the second electrode.
