[Background technology]

[0004] Generally, lighting devices are installed on furniture such as beds, desks, showcases, dressing tables, etc., to improve interior design and illuminate specific spaces. The lighting devices installed on the furniture can enhance aesthetic effects, and the lighting devices can also brighten specific spaces, providing functional effects.

[0005] A lighting device equipped with a diffusion plate may be installed in an internal shelf such as a showcase or built-in shelf equipped with shelves and hangers. By installing a lighting device in the internal shelf, the interior effect of the internal shelf can be improved and a specific point of the internal shelf can be brightened. The lighting device installed in the internal shelf may be installed in the shelf or hanger equipped in the internal shelf. However, installing a lighting device in a shelf or hanger has the following problems.

[0006] When installing a lighting device on a shelf or hanger, a point on the shelf or hanger where the lighting device is installed must be electrically connected to the outside.

[0069] 2 and 3, the first electrode 130 is provided on the connection bracket 120 and is connected to an electrical connection line 121 extending to the outside. The electrical connection line 121 can be connected to an external source, and the electrical connection line 121 includes an electric wire extending to the outside.

[0070] The first electrode 130 is electrically connected to the electrical connection wire 121 and is provided on the connecting bracket 120. The first electrode 130 may be a pair of electrodes including a cathode and an anode. The pair of electrodes may be electrically connected to the pair of electrical connection wires 121.

[0071] The pillar 140 may be fitted into an internal space of the connection bracket 120 and may be coupled to the connection bracket 120, and the pillar 140 may be coupled perpendicularly to the connection bracket 120. By coupling the connection bracket 120 to the bottom plate 110 and coupling the pillar 140 to the connection bracket 120, the pillar 140 can be installed perpendicularly to the bottom plate 110.

[0072] The second electrode 150 extends along the height direction of the pillar 140. The second electrode 150 may be a pair of electrodes including a cathode and an anode.

[0073] The second electrode 150 may come into contact with the first electrode 130 when the pillar 140 is coupled to the connecting bracket 120. When the pillar 140 is coupled to the connecting bracket 120 and the second electrode 150 comes into contact with the first electrode 130, the cathode of the second electrode 150 may come into contact with the cathode of the first electrode 130 and the anode of the second electrode 150 may come into contact with the anode of the first electrode 130. Thus, the first electrode 130 and the second electrode 150 may be electrically connected to each other.

[0074] The first electrode 130 according to an embodiment of the present invention includes a first electrode connection part 131 that protrudes from an upper part of the connecting bracket 120 and bends outward. The second electrode 150 according to an embodiment of the present invention may be formed of a thin film provided on the inner side of the pillar 140 and extending along the height direction of the pillar 140.

[0075] 3 and 4, when the pillar portion 140 is coupled to the connecting bracket 120, the first electrode connection portion 131 comes into contact with the second electrode 150 made of a thin film, so that the first electrode 130 and the second electrode 150 are electrically connected to each other.

[0076] Here, the first electrode connector 131 may include a cathode and an anode. When the first electrode connector 131 is in contact with the second electrode 150 made of a thin film, the cathode of the second electrode 150 may be in contact with the cathode of the first electrode connector 131, and the anode of the second electrode 150 may be in contact with the anode of the first electrode connector 131.

[0077] In this manner, in a system furniture equipped with a shelf fixing device according to an embodiment of the present invention, the first electrode 130 and the second electrode 150 can be brought into contact with each other and electrically connected simply by connecting or assembling the pillar portion 140 to the connecting bracket 120.

[0078] According to an embodiment of the present invention, the first electrode connection portion 131 may be made of an elastic material, and the first electrode connection portion 131 may be in an outwardly expanded state before the pillar portion 140 is coupled to the connecting bracket 120.

[0079] 4, when the pillar 140 is coupled to the connecting bracket 120, the first electrode connection parts 131 that are spread outward are gathered inward by the pillar 140. That is, the pillar 140 may be pressed into the connecting bracket 120 by gathering the first electrode connection parts 131 that are spread outward inward.

[0080] When the first electrode connection parts 131 are gathered inward by the pillar parts 140, an elastic restoring force is generated from the first electrode connection parts 131 made of an elastic material. When the pillar parts 140 are coupled to the connecting bracket 120, the first electrode connection parts 131 may be elastically pressed to spread outward due to the elastic restoring force.

[0081] In this manner, when the pillar portion 140 is coupled to the connecting bracket 120, the first electrode connection portion 131 is elastically pressed to expand outward, thereby allowing the first electrode connection portion 131 to be firmly in contact with the second electrode 150.

[0082] According to an embodiment of the present invention, the pillar 140 includes a rail 141 having a plurality of coupling holes 142 formed along a height direction of the pillar 140. The coupling holes 142 are holes to which hooks 162, which will be described later, are coupled, and may be holes penetrating the rail 141.

[0083] The rail 141 may have a plurality of the coupling holes 142 along the height direction of the pillar 140. The rail 141 may be a member that is fitted and coupled to the pillar 140, but is not limited thereto. The rail 141 may be manufactured integrally with the pillar 140.

[0084] Referring to FIG. 5, the shelf 160 includes a connecting portion 161 having a plurality of hook portions 162 each having a hook shape so as to fit into the connecting hole 142 of the rail 141, and a support portion 163 provided between the two connecting portions 161.

[0085] The connecting portion 161 of the shelf 160 may be a cantilever beam, and one side of the connecting portion 161 may be provided with a plurality of hook-shaped hook portions 162. The connecting portion 161 may be provided on both sides of the shelf 160.

[0086] 3 and 6, the hook portion 162 having a hook shape is fitted into the coupling hole 142, thereby coupling the connecting portion 161 to the post portion 140. The hook portion 162 may be coupled to one or more of the coupling holes 142.

[0087] According to an embodiment of the present invention, the height at which the connecting portion 161 is connected to the column 140 can be adjusted by changing the positions at which the hook portion 162 is connected to the plurality of connecting holes 142. Thus, the height at which the shelf 160 is connected to the column 140 can be adjusted.

[0088] 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 provided on the hook portion 162 of the connecting portion 161, and when the connecting portion 161 is coupled to the pillar portion 140, the second electrode 150 and the third electrode 170 may be in contact with each other. The third electrode 170 may be a pair of electrodes including a cathode and an anode.

[0089] When the connection portion 161 is coupled to the pillar portion 140, the cathode of the third electrode 170 may be in contact with the cathode of the second electrode 150, and the anode of the third electrode 170 may be in contact with the anode of the second electrode 150. Thus, the second electrode 150 and the third electrode 170 are electrically connected to each other.

[0090] As described above, the second electrode 150 is made of a thin film and extends along the height direction of the pillar 140. Therefore, no matter at what height the shelf 160 is coupled to the pillar 140, the second electrode 150 and the third electrode 170 can come into contact with each other and be electrically connected to each other.

[0091] According to an embodiment of the present invention, the third electrode 170 may include a third electrode connection portion 171 that is curved and protrudes outward from the hook portion 162. Referring to FIG 6, the third electrode connection portion 171 may be curved and protrude outward from the hook portion 162.

[0092] When the hook portion 162 is fitted into the connecting hole 142 of the rail 141, the third electrode connection portion 171 protruding from the hook portion 162 comes into contact with the second electrode 150, so that the third electrode 170 and the second electrode 150 are electrically connected to each other.

[0093] Here, the third electrode connector 171 may include a cathode and an anode. When the third electrode connector 171 is in contact with the second electrode 150 made of a thin film, the cathode of the second electrode 150 may be in contact with the cathode of the third electrode connector 171, and the anode of the second electrode 150 may be in contact with the anode of the third electrode connector 171.

[0094] In this manner, the system furniture equipped with the shelf fixing device according to an embodiment of the present invention can electrically connect the second electrode 150 and the third electrode 170 simply by connecting or assembling the hook portion 162 of the shelf 160 to the pillar portion 140.

[0095] According to an embodiment of the present invention, the second electrode 150 is made of a thin film extending along the height direction of the pillar portion 140, so that the third electrode 170 and the second electrode 150 can be brought into contact with each other and electrically connected regardless of the height at which the hook portion 162 is coupled to the pillar portion 140.

[0096] That is, regardless of which position the hook portion 162 is fitted into and coupled to among the coupling holes 142, the second electrode 150 and the third electrode 170 come into contact with each other and are electrically connected to each other. As a result, even if the height at which the shelf 160 is installed relative to the column portion 140 is adjusted, the second electrode 150 and the third electrode 170 come into contact with each other and are electrically connected to each other.

[0097] According to an embodiment of the present invention, the third electrode connection portion 171 may be made of an elastic material, and the third electrode connection portion 171 may be in an outwardly expanded state before the hook portion 162 is fitted into the coupling hole 142.

[0098] When the hook portion 162 is fitted into the coupling hole 142, the third electrode connection portion 171 spreading outward is gathered inward by the pillar portion 140. That is, the hook portion 162 may be forcibly fitted into the inner side of the pillar portion 140 through the coupling hole 142 while gathering the third electrode connection portion 171 spreading outward inward.

[0099] When the third electrode connection parts 171 are gathered inward by the pillar parts 140, an elastic restoring force is generated in the third electrode connection parts 171 made of an elastic material. When the hook parts 162 are fitted into the coupling holes 142, the third electrode connection parts 171 may be elastically pressed to expand outward by the elastic restoring force.

[0100] In this manner, when the hook portion 162 is engaged with the coupling hole 142, the third electrode connection portion 171 is elastically pressed to expand outward, thereby allowing the third electrode connection portion 171 to be firmly in contact with the second electrode 150.

[0101] The support portion 163 of the shelf 160 is provided between the two connecting portions 161. The support portion 163 may have a plate shape, and the support portion 163 may be a support plate of the shelf 160.

[0102] A furniture system equipped with a shelf fixing device according to an embodiment of the present invention may include a light 180 provided on the shelf 160 and connected to the third electrode 170. The light 180 is electrically connected to the third electrode 170, and the light 180 may be provided at various points on the shelf 160.

[0103] The light 180 may be connected to the third electrode 170 via an electric wire or other electrical connection device, and may be in the form of a diffusion plate. However, the light 180 is not limited thereto, and may be provided on the shelf 160 in various forms. As can be expected from the shape of the light 180, the light 180 can also be used as a hanger rod.

[0104] The first electrode 130 provided on the connecting bracket 120 is supplied with electricity through the electrical connection line 121, and the electricity supplied to the first electrode 130 is transferred to the second electrode 150. The electricity transferred to the second electrode 150 is transferred to the third electrode 170, and the electricity transferred to the third electrode 170 is transferred to the light 180, so that light is emitted from the light 180.

[0105] The connecting portion 161 and the support portion 163 of the shelf 160 according to the embodiment of the present invention may be separate members. The connecting portion 161 is first connected to the column portion 140, and the support portion 163 is then placed between the two connecting portions 161, whereby the shelf 160 can be installed in the system furniture.

[0106] When the support part 163 is installed between the two connecting parts 161, the support part 163 may be lifted and installed between the two connecting parts 161. At this time, if there is no separate device for fixing the support part 163, there is a risk that the support part 163 may be lifted and separated from the connecting part 161.

[0107] The shelf fixing device 200 and the locking member 164 are for fixing the support part 163 to the connecting part 161 while preventing the support part 163 from being lifted and separated from the connecting part 161. Referring to FIG. 7, the shelf fixing device 200 may be provided on the connecting part 161, and referring to FIG. 8, the locking member 164 may be provided on the support part 163.

[0108] According to an embodiment of the present invention, the shelf fixing device 200 includes a housing 210, a switch 220, and a slider 230. The housing 210 has an internal space and is coupled to the connecting portion 161.

[0109] 7, the housing 210 may be coupled to the inner surface of the connecting part 161 via a screw or the like. The switch 220 is provided in the housing 210, and the slider 230 protrudes outward from the housing 210 when the switch 220 is actuated.

[0110] 9(a), the slider 230 may be disposed inside the housing 210 and not protruding outside the housing 210. This state may be an unlocked state of the shelf fixing device 200.

[0111] 9(b), the slider 230 may be protruded outward from the housing 210. In this state, the shelf fixing device 200 may be in an unlocked state.

[0112] Also, when the switch 220 is pressed again, the slider 230 may re-enter the interior of the housing 210 and no longer protrude outside the housing 210 .

[0113] 8 and 10, the locking member 164 is provided on the side of the support portion 163, and the locking member 164 includes an insertion space 165 into which the shelf fixing device 200 is inserted and a locking protrusion 166 provided at the bottom of the insertion space 165.

[0114] 11(a) and 11(b), when the support part 163 is raised and installed between the two connecting parts 161, the shelf fixing device 200 may be inserted into the insertion space of the locking member 164. At this time, the sliding part 230 of the shelf fixing device 200 may not protrude outside the housing 210 as shown in FIG.

[0115] When the support part 163 is raised and installed between the two connecting parts 161, the slider 230 is operated via the switch 220. The slider 230 may be protruded to the outside of the housing 210 by the operation of the switch 220.

[0116] When the sliding part 230 protrudes outward from the housing 210, the sliding part 230 may be disposed on the upper part of the locking protrusion 166 as shown in Fig. 11(b). By disposing the sliding part 230 on the upper part of the locking protrusion 166 as shown in Fig. 11(b), it is possible to prevent the support part 163 from being lifted up and separated from the connecting part 161.

[0117] Specifically, when the support portion 163 is lifted, the locking protrusion 166 provided on the locking member 164 of the support portion 163 comes into contact with the sliding portion 230, thereby preventing the support portion 163 from being lifted and coming off the connecting portion 161.

[0118] According to an embodiment of the present invention, the locking member 164 may be coupled to the support portion 163, or the locking member 164 may be formed integrally with the support portion 163.

[0119] When the support part 163 is made of wood, the locking member 164 can be separately manufactured and connected to the side of the support part 163. When the support part 163 is made of a material having hardness such as iron, the locking member 164 can be formed integrally with the support part 163.

[0120] Specifically, when the support portion 163 is made of a material having hardness such as iron, the locking member 164 may be formed integrally with the support portion 163, and the structure of the locking member 164 may be formed on the side of the support portion 163.

[0121] Hereinafter, a method for moving the slider 230 by operating the switch 220 of the shelf fixing device 200 according to an embodiment of the present invention will be described in detail.

[0122] 12(a) and 12(b), the switch 220 according to the embodiment of the present invention may include a moving protrusion 221 protruding outward from the switch 220. The moving protrusion 221 may be a bar-shaped protrusion protruding from both sides of the switch 220.

[0123] The shelf fixing device 200 according to the embodiment of the present invention may include a fixing part 240 that is inserted into the housing 210 and has a moving groove 241 extending in one direction so that the moving protrusion 221 can be inserted therein.

[0124] The fixing part 240 is inserted into the housing 210, and has a space inside in which the switch 220 can move. The fixing part 240 has on both sides thereof the moving grooves 241 into which the moving protrusions 221 can be inserted, and when the switch 220 is inserted into the fixing part 240, the moving protrusions 221 can be inserted into the moving grooves 241.

[0125] The moving groove 241 extends in one direction, and may be a groove extending in a vertical direction or in a straight line. Referring to Figures 13(a) and 13(b), the moving protrusion 221 can move up and down along the moving groove 241, so that the switch 220 moves in a direction parallel to the one direction in which the moving groove 241 extends.

[0126] 13(a), 13(b), 14(a) and 14(b), a spring 250 may be provided between the fixed part 240 and the switch 220. One side of the spring 250 may be in contact with the fixed part 240, and the other side of the spring 250 may be in contact with the switch 220. The spring 250 may apply an elastic restoring force to the switch 220.

[0127] 14(a) and 14(b), the sliding part 230 may be provided with a sliding groove 231 extending obliquely with respect to the moving groove 241. The sliding groove 231 is a groove provided on a side surface of the sliding part 230, and the sliding groove 231 may be provided on both side surfaces of the sliding part 230.

[0128] 12(a) and 12(b), the moving protrusion 221 of the switch 220 may be inserted into the sliding groove 231 and the moving groove 241 at the same time. Specifically, the switch 220 is fitted into the fixed part 240 while the moving protrusion 221 is inserted into the moving groove 241. Then, the sliding part 230 is fitted to the outside of the fixed part 240 while the moving protrusion 221 is inserted into the sliding groove 231.

[0129] Here, the fixing part 240 may be inserted into the housing 210 and fixedly coupled to the housing 210 , and the switch 220 and the sliding part 230 may be allowed to move relative to the housing 210 .

[0130] The moving protrusion 221 of the switch 220 is inserted into the sliding groove 231 and the moving groove 241 at the same time, so that the sliding part 230 slides and moves according to the operation of the switch 220 .

[0131] Specifically, as shown in FIG. 12(a), when the switch 220 is pressed in a state in which the sliding portion 230 does not protrude outside the housing 210, the switch 220 moves upward along the moving groove 241.

[0132] 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 causes the sliding portion 230 to slide while pushing it toward the outside of the housing 210 as shown in Figure 12 (b).

[0133] Here, when the switch 220 is pressed in a state in which the sliding portion 230 does not protrude outside the housing 210 as shown in FIG. 12(a), the moving protrusion 221 of the switch 220 will stop at a point at the upper part of the moving groove 241 due to the path guide portion 260 described later as shown in FIG. 12(b).

[0134] When the switch 220 is pressed again with the sliding portion 230 protruding outside the housing 210 as shown in FIG. 12(b), the force of the spring 250 causes the moving protrusion 221 of the switch 220 to move downward along the moving groove 241, so that the sliding portion 230 no longer protrudes outside the housing 210 as shown in FIG. 12(a).

[0135] According to an embodiment of the present invention, the sliding part 230 may have an extension groove 232 extending in one direction. The extension groove 232 is provided on an upper part of the sliding groove 231. The extension groove 232 may be a groove in which the moving protrusion 221 is disposed when the moving protrusion 221 of the switch 220 is stopped at a point on the upper part of the moving groove 241 by a path guide part 260 described later.

[0136] The shelf fixing device 200 according to the embodiment of the present invention may include a path guide portion 260 coupled to the fixing portion 240 having a rod shape and in contact with one surface 222 of the switch 220 .

[0137] 15(a) and 15(b), the path guiding unit 260 has a bar shape and is fixedly connected to the fixed unit 240. The path guiding unit 260 is movable along one surface 222 of the switch 220 according to the operation of the switch 220.

[0138] In particular, one side of the route guiding unit 260 may be fixedly coupled to the fixed unit 240 , and the other side of the route guiding unit 260 may be in contact with one surface 222 of the switch 220 .

[0139] According to an embodiment of the present invention, when the moving protrusion 221 of the switch 220 is maintained in a stopped state at an upper point of the moving groove 241, the sliding part 230 is maintained in a protruding state outside the housing 210. Also, when the moving protrusion 221 of the switch 220 is disposed in a lower part of the moving groove 241, the sliding part 230 may not protrude outside the housing 210.

[0140] The path guide unit 260 may be a member that adjusts the movement of the switch 220 so that the moving protrusion 221 of the switch 220 is maintained in a stopped state at an upper point of the moving groove 241 .

[0141] A first path 223 may be provided on one surface 222 of the switch 220, which contacts the one surface of the switch 220 when the route guide unit 260 moves downward. Also, a second path 224 may be provided on one surface of the switch 220, which contacts the one surface 222 of the switch 220 when the route guide unit 260 moves upward.

[0142] The first path 223 and the second path 224 may be points where the path guide unit 260 contacts one surface 222 of the switch 220. When the switch 220 moves upward along the movement groove 241, the path guide unit 260 moves downward along the first path 223, and when the switch 220 moves, it moves downward along the movement groove 241, and the path guide unit 260 moves upward along the second path 224.

[0143] 16(a) and 16(b), one surface 222 of the switch 220 may be provided with a first path guiding protrusion 270, a second path guiding protrusion 280, and a third path guiding protrusion 290 protruding outward from one surface 222 of the switch 220.

[0144] 16(a) and 16(b), the first path guiding protrusion 270 is provided inside one surface 222 of the switch 220. Specifically, the first path guiding protrusion 270 may be provided in a center portion of one surface 222 of the switch 220.

[0145] An upper portion of the first path guiding protrusion 270 may be provided with a first upper downward incline 271 that forms a downward incline from a central axis 225 of one surface 222 of the switch 220 toward the first path 223, and a second upper downward incline 272 that forms a downward incline from the central axis 225 of one surface 222 of the switch 220 toward the second path 224.

[0146] 16(a) and 16(b), a lower portion of the first path guiding protrusion 270 may be provided with a first lower downward incline 273 that forms a downward incline from a central axis 225 of one face 222 of the switch 220 toward the first path 223, and a second lower downward incline 274 that forms a downward incline from the central axis 225 of one face 222 of the switch 220 toward the second path 224.

[0147] Here, the upper portion on one surface 222 of the switch 220 may be the direction in which the movable protrusion 221 is provided in Figures 16(a) and 16(b), and the lower portion on one surface 222 of the switch 220 may be the opposite direction in which the movable protrusion 221 is provided in Figures 16(a) and 16(b).

[0148] 16(a) and 16(b), the second path guiding protrusion 280 is provided at a lower portion of the first path 223. The second path guiding protrusion 280 may have an upward inclination 281 formed from a central axis 225 of one surface 222 of the switch 220 toward the first path 223.

[0149] 16(a) and 16(b), the third path guiding protrusion 290 is provided at a lower part of the second lower downward inclination 274. The third path guiding protrusion 290 may have a downward inclination 291 formed from a central axis 225 of one surface 222 of the switch 220 toward the second path 224.

[0150] 15(a) and 16(a), when the sliding part 230 does not protrude outside the housing 210, the path guide part 260 may be disposed in an initial position.

[0151] When the switch 220 is pressed, the path guide unit 260 moves along the first path 223, so that the moving protrusion 221 of the switch 220 may be maintained in a stopped state at an upper point of the moving groove 241.

[0152] Specifically, when the switch 220 is pressed while the sliding portion 230 is not protruding outside the housing 210, the switch 220 moves upward and the path guidance portion 260 moves downward along one surface 222 of the switch 220.

[0153] When the path guide portion 260 moves downward along one surface 222 of the switch 220 , the path guide portion 260 moves to the first path 223 along the first upper downward inclination 271 of the first path guide protrusion 270 .

[0154] When the path guide unit 260 moves along the first path 223, the path guide unit 260 comes into contact with the upward incline 281 of the second path guide protrusion 280 provided at the lower part of the first path 223, and is thereby positioned at the lower part between the first lower downward incline 273 and the second lower downward incline 274 of the first path guide protrusion 270.

[0155] When the force pressing 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 guiding part 260 moves upward, so that the path guiding part 260 is caught between the first lower downward incline 273 and the second lower downward incline 274 of the first path guiding protrusion 270.

[0156] As the path guiding portion 260 is engaged between the first lower downward inclination 273 and the second lower downward inclination 274 of the first path guiding protrusion 270, the moving protrusion 221 of the switch 220 is maintained in a stopped state at an upper point of the moving groove 241. When the moving protrusion 221 of the switch 220 is maintained in a stopped state at an upper point of the moving groove 241, the sliding portion 230 may be in a protruding state outside the housing 210.

[0157] 15(b) and 16(b), when the switch 220 is pressed again with the sliding portion 230 protruding outside the housing 210, the path guide portion 260 moves along the second path 224.

[0158] Specifically, when the switch 220 is pressed again with the sliding portion 230 protruding outside the housing 210, the switch 220 moves upward and the path guidance portion 260 moves downward along one surface 222 of the switch 220.

[0159] When the path guiding part 260 moves downward along one surface 222 of the switch 220, the path guiding part 260 comes into contact with the downward incline 291 of the third path guiding protrusion 290, leaves between the first lower downward incline 273 and the second lower downward incline 274 of the first path guiding protrusion 270, and moves to the second path 224.

[0160] When the force pressing the switch 220 is removed, the force of the spring 250 causes the switch 220 to move downward, and the path guide unit 260 to move upward.

[0161] At this time, since the path guide portion 260 moves away from between the first lower downward incline 273 and the second lower downward incline 274 of the first path guide protrusion 270 and moves to the second path 224, the path guide portion 260 moves upward along the second path 224.

[0162] The path guide portion 260, which has moved upward along the second path 224, may come into contact with the second upper downward incline 272 of the first path guide protrusion 270, thereby causing the path guide portion 260 to return to its initial position in which the sliding portion 230 does not protrude outside the housing 210.

[0163] As described above, when the switch 220 is pressed once, the moving protrusion 221 of the switch 220 can be maintained in a stopped state at the upper point of the moving groove 241 via the path guide unit 260. When the switch 220 is pressed again, the moving protrusion 221 of the switch 220 can be repositioned to the lower part of the moving groove 241.

[0164] According to an embodiment of the present invention, when the moving protrusion 221 of the switch 220 is maintained in a stopped state at an upper point of the moving groove 241, the sliding part 230 may be maintained in a protruding state to the outside of the housing 210. Also, when the moving protrusion 221 of the switch 220 is disposed in a lower part of the moving groove 241, the sliding part 230 may not be protruding to the outside of the housing 210.

[0165] In this manner, the system furniture equipped with the shelf fixing device according to an embodiment of the present invention can slide and move the sliding part 230 in a state where it is protruding or not protruding outside the housing 210 depending on the operation of the path guide part 260 and the switch 220.

[0166] 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 obtained by chamfering one side of the sliding portion 230.

[0167] When one side of the sliding part 230 is chamfered, the frictional force generated between the sliding part 230 and the fixed part 240 is reduced, so that the sliding part 230 can slide smoothly.

[0168] 3 and 4, the pillar 140 according to the embodiment of the present invention may be provided with wings 143 protruding outward from the pillar 140. A block 190 having a hexahedral shape may be coupled to the wings 143. The wings 143 may be protrusions protruding outward from the pillar 140, and the block 190 may be fixedly coupled to the wings 143.

[0169] The system furniture equipped with the shelf fixing device according to the embodiment of the present invention may further include a back panel 191 provided between the two pillars 140. The back panel 191 may have a plate shape and may be a plate provided between the two pillars 140.

[0170] The back plate 191 may be installed via the block 190. Specifically, the back plate 191 can be connected to the block 190 by fixing the contact points between the back plate 191 and the block 190 via a pin or a tacker. By fixing and connecting the back plate 191 via the block 190, the back plate 191 can be easily installed between the two pillars 140.

[0171] The system furniture equipped with the shelf fixing device according to the embodiment of the present invention may be a built-in shelf. When the system furniture equipped with the shelf fixing device according to the embodiment of the present invention is a built-in shelf, the system furniture can be installed on a wall via the block 190.

[0172] Specifically, the bottom plate 110 and the pillars 140 are connected via the connecting brackets 120, and the block 190 is fixed to the wall. Then, the back plate 191 is connected to the block 190 using pins, tackers, etc., so that the system furniture can be installed on the wall.

[0173] The system furniture equipped with the shelf fastening device according to the embodiment of the present invention has an advantage that the system furniture having a built-in shelf can be easily installed on the wall by fastening the system furniture to the wall via the block 190. Furthermore, when dismantling the system furniture equipped with the shelf fastening device according to the embodiment of the present invention, the system furniture can be easily dismantled from the wall by removing the block 190 from the wall.

[0174] As described above, the system furniture equipped with the shelf fixing device according to the embodiment of the present invention has an advantage that the system furniture having a built-in shelf can be easily installed, dismantled, and reinstalled by installing and dismantling the system furniture via the block 190.

[0175] The shelf fixing device 200 used in the system furniture according to an embodiment of the present invention is provided in the connecting portion 161 in the system furniture having a shelf 160 including a connecting portion 161 having a plurality of hook portions 162 and a support portion 163 provided between the two connecting portions 161.

[0176] The support portion 163 is provided with a locking member 164 including an insertion space 165 into which the shelf fixing device 200 is inserted and a locking protrusion 166 provided at the bottom of the insertion space 165. The shelf fixing device 200 used in the system furniture according to an embodiment of the present invention includes a housing 210 having an internal space and connected to the connecting portion 161, a switch 220 provided in the housing 210, and a sliding portion 230 that protrudes outward from the housing 210 upon activation of the switch 220. When the sliding portion 230 protrudes outward from the housing 210 upon activation of the switch 220, the sliding portion 230 can be positioned on the top of the locking protrusion 210.

[0177] The shelf fixing device 200 used in the system furniture according to the embodiment of the present invention is the same as the shelf fixing device 200 included in the system furniture equipped with the shelf fixing device according to the embodiment of the present invention described above, so a detailed description will be omitted.

[0184] As described above, the present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will appreciate that various modifications and variations of the embodiments are possible. Therefore, the true technical scope of the present invention should be determined by the technical ideas of the appended claims.

[0185] Meanwhile, embodiments according to other aspects of the present invention will be presented. In the second and third embodiments presented below, the explanations of the same or similar configurations as those of the above-mentioned best mode are applied in the same manner or with appropriate modifications, and duplicate explanations will be omitted.

[0186] The second embodiment relates to a system furniture equipped with a rod connecting device, which allows electrical connection, adjusts the height of the hanger, is easy to install and disassemble, and allows multiple hangers to be installed consecutively at the same height. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to Figures 1 to 4 and 18 to 23.

[0187] The system furniture equipped with the rod connector according to the embodiment of the present invention includes a base plate 110, a column portion 140, a first rod connector 360, a second rod connector 370, and a rod connector 400.

[0188] 17 and 2, the base plate 110 has a plate shape, and may be a lower plate of a system furniture. A plurality of base plates 110 may be provided, and the base plate 110 may be installed on the ground.

[0189] The explanation regarding FIGS. 2 to 4 applies to the above-mentioned best mode.

[0190] Referring to FIG. 18, the first rod connector 360 and the second rod connector 370 are connected to the column 140, and the first rod connector 360 and the second rod connector 370 may be hangers connected to a system furniture.

[0191] The first rod connector 360 includes a rod-shaped first rod 361 and a first connecting portion 362 provided on one side of the first rod 361 and having a plurality of hook portions 380 shaped like hooks to fit into the connecting holes 142 of the rail 141.

[0192] The second rod connector 370 includes a rod-shaped second rod 371 and a second connecting portion 372 provided on one side of the first rod 361 and having a plurality of hook portions 380 shaped like hooks to fit into the connecting holes 142 of the rail 141.

[0193] The first rod 361 and the second rod 371 may be rods on which hangers, clothes, etc. can be hung. The first connecting part 362 and the second connecting part 372 may be coupled to the column part 140 to install the first rod 361 and the second rod 371.

[0194] The first connecting portion 362 and the second connecting portion 372 may be formed as a cantilever beam, 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 having a hook shape.

[0195] 3 and 19, the hook portion 380 having a hook shape is fitted into the coupling hole 142, thereby coupling the first coupling portion 362 and the second coupling portion 372 to the pillar portion 140. The hook portion 380 may be coupled to one or more of the coupling holes 142.

[0196] According to an embodiment of the present invention, the height at which the first connecting part 362 and the second connecting part 372 are connected to the pillar part 140 can be adjusted by changing the position at which the hook part 380 is connected to the plurality of connecting holes 142. Thus, the height at which the first rod coupler 360 and the second rod coupler 370 are connected to the pillar part 140 can be adjusted.

[0197] The system furniture including the rod connector according to the embodiment of the present invention may further include a third electrode 381. The third electrode 381 is provided on the first connecting part 362 and the second connecting part 372, and contacts the second electrode 150 when the first connecting part 362 and the second connecting part 372 are coupled to the pillar part 140. The third electrode 381 may be a pair of electrodes including a cathode and an anode.

[0198] When the first connecting portion 362 and the second connecting portion 372 are coupled to the pillar portion 140, the cathode of the third electrode 381 may be in contact with the cathode of the second electrode 150, and the anode of the third electrode 381 may be in contact with the anode of the second electrode 150. Thus, the second electrode 150 and the third electrode 381 are electrically connected to each other.

[0199] As described above, the second electrode 150 is made of a thin film and extends along the height direction of the pillar 140. Therefore, no matter at what height the first rod coupler 360 and the second rod coupler 370 are coupled to the pillar 140, the second electrode 150 and the third electrode 381 can be brought into contact with each other and electrically connected to each other.

[0200] According to an embodiment of the present invention, the third electrode 381 may be provided on the first connecting portion 362 and the second connecting portion 372, and the third electrode 381 may be provided on the hook portion 380 of the first connecting portion 362 and the second connecting portion 372.

[0201] The third electrode 381 may include a third electrode connection portion 382 that is curved and protrudes outward from the hook portion 380. Referring to FIG 7, the third electrode connection portion 382 may be curved and protrude outward from the hook portion 380.

[0202] As described above, the second electrode 150 may be formed of a thin film provided inside the pillar 140 and extending along the height direction of the pillar 140. When the hook portion 380 is fitted into the coupling hole 142 of the rail 141, the third electrode connection portion 382 protruding from the hook portion 380 comes into contact with the second electrode 150, so that the third electrode 381 and the second electrode 150 are electrically connected to each other.

[0203] Here, the third electrode connector 382 may include a cathode and an anode. When the third electrode connector 382 is in contact with the second electrode 150 made of a thin film, the cathode of the second electrode 150 may be in contact with the cathode of the third electrode connector 382, ​​and the anode of the second electrode 150 may be in contact with the anode of the third electrode connector 382.

[0204] In this manner, the system furniture equipped with the rod connecting device according to an embodiment of the present invention can electrically connect the second electrode 150 and the third electrode 381 simply by coupling or assembling the hook portions 380 of the first connecting portion 362 and the second connecting portion 372 to the pillar portion 140.

[0205] 4 and 20, the second electrode 150 according to an embodiment of the present invention is formed of a thin film extending along the height direction of the pillar portion 140, so that the third electrode 381 and the second electrode 150 can be in contact with each other and electrically connected regardless of the height at which the hook portion 380 is connected to the pillar portion 140.

[0206] That is, the second electrode 150 and the third electrode 381 come into contact with each other and are electrically connected to each other regardless of where the hook portion 380 is fitted into and coupled to the coupling holes 142. As a result, even if the height at which the first rod coupler 360 and the second rod coupler 370 are installed relative to the pillar portion 140 is adjusted, the second electrode 150 and the third electrode 381 come into contact with each other and are electrically connected to each other.

[0207] According to an embodiment of the present invention, the third electrode connection portion 382 may be made of an elastic material, and the third electrode connection portion 382 may be in an outwardly expanded state before the hook portion 380 is engaged with the coupling hole 142.

[0208] 20, when the hook portion 380 is fitted into the coupling hole 142, the outwardly extending third electrode connection portion 382 is gathered inward by the pillar portion 140. That is, the hook portion 380 may be forcibly fitted into the inner side of the pillar portion 140 through the coupling hole 142 while gathering the outwardly extending third electrode connection portion 382 inward.

[0209] When the third electrode connection parts 382 are gathered inward by the pillar parts 140, an elastic restoring force is generated in the third electrode connection parts 382 made of an elastic member. When the hook parts 380 are fitted into the coupling holes 142, the third electrode connection parts 382 may be elastically pressed to expand outward by the elastic restoring force.

[0210] In this manner, when the hook portion 380 is engaged with the coupling hole 142, the third electrode connection portion 382 is elastically pressed to expand outward, thereby allowing the third electrode connection portion 382 to be firmly in contact with the second electrode 150.

[0211] A system furniture including the rod connecting device according to an embodiment of the present invention may include a light 392 provided on at least one of the first rod 361 and the second rod 371.

[0212] The light 392 is electrically connected to the third electrode 381, and may be provided at various points on the first rod 361 and the second rod 371. The light 392 may be connected to the third electrode 381 via an electric wire or other electrical connection device, and the light 392 may be in the form of a diffusion plate. However, the light 392 is not limited thereto, and may be provided on the first rod 361 and the second rod 371 in various forms.

[0213] The first electrode 130 provided on the connecting bracket 120 is supplied with electricity through the electrical connection line 121, and the electricity supplied to the first electrode 130 is transferred to the second electrode 150. The electricity transferred to the second electrode 150 is transferred to a third electrode 381, and the electricity transferred to the third electrode 381 is transferred to the light 392, so that light is emitted from the light 392.

[0214] According to an embodiment of the present invention, the first rod coupler 360 may have the first connecting portion 362 on both sides, or the first rod coupler 360 may have the first connecting portion 362 on only one side.

[0215] According to an embodiment of the present invention, the second rod connector 370 may be provided with the second connecting portion 372 only on one side, and the other side of the second connecting portion 372 may be open with no second connecting portion 372 provided.

[0216] When the first rod coupler 360 and the second rod coupler 370 are coupled to the column portion 140, if the second connecting portion 372 is provided on both one and the other sides of the second rod coupler 370, the first rod coupler 360 and the second rod coupler 370 cannot be installed continuously at the same height.

[0217] Specifically, when the first rod connector 360 and the second rod connector 370 are installed consecutively at the same height in a system furniture, if the second connecting part 372 is provided on both one and the other sides of the second rod connector 370, interference will occur between the first connecting part 362 provided on one side of the first rod connector 360 and the second connecting part 372 provided on the other side of the second rod connector 370.

[0218] More specifically, only one of the first connecting portion 362 provided on one side of the first rod coupler 360 and the second connecting portion 372 provided on the other side of the second rod coupler 370 is fitted into the rail 141 provided on the pillar portion 140. Therefore, if the second connecting portion 372 is provided on both one and the other sides of the second rod coupler 370, the first rod coupler 360 and the second rod coupler 370 cannot be installed continuously at the same height.

[0219] Of course, a plurality of rails 141 may be installed on the pillar 140, and the first connecting part 362 provided on one side of the first rod connecting body 360 and the second connecting part 372 provided on the other side of the second rod connecting body 370 may be respectively connected to the rails 141. However, when a plurality of rails 141 are installed on the pillar 140, the volume of the system furniture increases and the aesthetic appearance is not good.

[0220] In order to solve this problem, the system furniture equipped with the rod connecting device according to the embodiment of the present invention may use the rod connecting device 400. The rod connecting device 400 connects the first connecting portion 362 of the first rod connecting body 360 and the other side of the second rod 371 of the second rod connecting body 370.

[0221] The rod connecting device 400 includes a first connecting member 410 and a second connecting member 420. Referring to Figures 19 and 20, one side of the first connecting portion 362 of the first rod connecting body 360 may be provided with a connecting member 363 having a connecting groove 364 extending in a longitudinal direction.

[0222] The coupling member 363 is coupled to a side surface of the first connecting portion 362, and the coupling groove 364 is formed in the coupling member 363. The coupling groove 364 is a groove extending in a longitudinal direction or in one direction, and a coupling protrusion 411, which will be described later, may be inserted into the coupling groove 364.

[0223] According to an embodiment of the present invention, the connecting member 363 may be a member separate from the first connecting portion 362 and may be connected to a side of the first connecting portion 362, or the connecting member 363 may be integral with the first connecting portion 362.

[0224] The first connecting member 410 includes a connecting protrusion 411 extending in a longitudinal direction and inserted into the connecting groove 364. The connecting protrusion 411 is a protrusion extending in a longitudinal direction or in one direction, and the connecting protrusion 411 may protrude outward from the first connecting member 410.

[0225] The coupling protrusion 411 may have a shape corresponding to the shape of the coupling groove 364 so as to be fitted into the coupling groove 364. According to an embodiment of the present invention, when the coupling protrusion 411 is inserted into the coupling groove 364 and the first connection member 410 is rotated, the coupling protrusion 411 may not come off from the coupling groove 364.

[0226] 20 and 21, an empty space is formed inside the coupling member 363. When the coupling protrusion 411 is inserted into the coupling groove 364 of the coupling member 363, the coupling protrusion 411 may rotate through the empty space of the coupling member 363.

[0227] The coupling protrusion 411 has a shape corresponding to the shape of the coupling groove 364 so that it can fit into the coupling groove 364. Therefore, when the coupling protrusion 411 is rotated, the coupling protrusion 411 gets caught on the outside of the coupling groove 364, and the coupling protrusion 411 does not come off the coupling groove 364.

[0228] The second connecting member 420 is coupled to the other side of the second rod 371 , and the first connecting member 410 may be rotatably coupled to the second connecting member 420 .

[0229] 21, 22(a) and 22(b), the second connecting member 420 may have a circular through-hole 421 penetrating the second connecting member 420. The first connecting member 410 may have a rotation protrusion 415 formed in a shape corresponding to the through-hole 421 so as to be fitted into the through-hole 421.

[0230] The inside of the rotation protrusion 415 may be provided with a first screw coupling hole 416 into which a screw 430 is inserted, and the screw 430 may pass through the through hole 421 on one side of the second connecting member 420 and be inserted into the first screw coupling hole 416.

[0231] When the rotation protrusion 415 of the first connecting member 410 is inserted into the through hole 421 of the second connecting member 420 and the screw 430 is engaged with the first screw engagement hole 416, the first connecting member 410 may be rotatably engaged with the second connecting member 420.

[0232] At this time, a bearing 431 may be provided between the screw 430 and the through hole 421. The bearing 431 prevents the screw 430 from contacting the second connecting member 420 and being fixed thereto.

[0233] Without the bearing 431, the screw 430 may come into contact with the second connecting member 420. If the screw 430 comes into contact with the second connecting member 420, frictional force may be generated between the screw 430 and the second connecting member 420 when the first connecting member 410 rotates, and the rotation of the first connecting member 410 may be restricted.

[0234] Here, since the screw 430 is coupled to the first screw coupling hole 416 of the first connecting member 410 , the screw 430 rotates together with the first connecting member 410 .

[0235] When the bearing 431 is provided between the screw 430 and the through hole 421, the screw 430 is prevented from contacting the second connecting member 420, so that the first connecting member 410 can rotate smoothly relative to the second connecting member 420.

[0236] 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. Referring to Fig. 22(a) and Fig. 22(b), the handle 414 protrudes outward from the first connecting member 410, and a force can be applied to the first connecting member 410 via the handle 414 to rotate the first connecting member 410 relative to the second connecting member 420.

[0237] According to an embodiment of the present invention, a rotation limiting protrusion 423 extending in a circumferential direction of the second connecting member 420 and protruding outward may be provided on one surface of the second connecting member 420. The rotation limiting protrusion 423 may extend in a circumferential direction of the second connecting member 420 by a specified angle based on the center of the second connecting member 420.

[0238] The rotation limiting protrusion 423 can limit the rotation of the first connecting member 410. Referring to Fig. 22(a) and Fig. 22(b), the handle 414 of the first connecting member 410 can protrude outward at a point where the rotation limiting protrusion 423 is not provided, and the handle 414 can be rotatable only at a point where the rotation limiting protrusion 423 is not provided.

[0239] Specifically, one surface of the second connecting member 420 has points along a circumferential direction where the rotation limiting protrusion 423 is provided and points where the rotation limiting protrusion 423 is not provided. The handle 414 of the first connecting member 410 may protrude outward at the points where the rotation limiting protrusion 423 is not provided, and when the handle 414 rotates, the handle 414 may come into contact with the rotation limiting protrusion 423.

[0240] When the handle 414 comes into contact with the rotation limiting protrusion 423, the rotation of the handle 414 may be limited by the rotation limiting protrusion 423. That is, the first connecting member 410 is rotatable only at points of 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 via the rotation limiting protrusion 423.

[0241] The rod coupling 400 according to an embodiment of the present invention can be installed in the following manner.

[0242] 22(a) and 22(b), the first connecting member 410 and the second connecting member 420 may be first coupled to each other via the screw 430 and the bearing 431. The second connecting member 420 may be coupled to the other side of the second rod 371, but if the second connecting member 420 is first coupled to the other side of the second rod 371, one side of the second connecting member 420 is blocked by the second rod 371.

[0243] The screw 430 must be coupled to the first connecting member 410 by passing through the through hole 421 at one side of the second connecting member 420, but if the second connecting member 420 is coupled to the other side of the second rod 371 first, the second rod 371 will cause a space for inserting the screw 430 to be eliminated. Therefore, it is preferable to couple the first connecting member 410 and the second connecting member 420 first via the screw 430 and the bearing 431.

[0244] After the first connecting member 410 and the second connecting member 420 are coupled together, the second connecting member 420 is coupled to the other side of the second rod 371. The second connecting member 420 is provided with a second screw coupling hole 422 penetrating the second connecting member 420, and the second rod 371 is provided with a screw coupling hole 373 into which a screw is fitted.

[0245] When a screw is inserted into the screw connection hole 373 of the second rod 371 through the second screw connection hole 422 from the other side of the second connecting member 420, the second connecting member 420 is connected to the other side of the second rod 371 with the first connecting member 410 connected to the second connecting member 420 as shown in FIG. 23.

[0246] Thereafter, when the coupling protrusion 411 of the first coupling member 410 is inserted into the coupling groove 364 and the first coupling member 410 is rotated via the handle 414, the coupling protrusion 411 does not come out of the coupling groove 364.

[0247] Since the coupling protrusion 411 is not removed from the coupling groove 364, the first connecting portion 362 of the first rod coupler 360 and the other side of the second rod 371 can be coupled to each other.

[0248] In this way, in a system furniture equipped with a rod connecting device according to an embodiment of the present invention, even if the second connecting part 372 is not provided on the other side of the second rod 371, the first rod connecting body 360 and the second rod connecting body 370 can be installed at the same height via the rod connecting device 400.

[0249] According to an embodiment of the present invention, a side of the first connecting member 410 may be provided with a side groove 417 that is dug into the inside of the first connecting member 410. As described above, the first connecting member 410 and the second connecting member 420 may be first coupled to each other, and then the second connecting member 420 may be coupled to the second rod 371.

[0250] 22(a), 22(b), and 23, the first connecting member 410 is disposed on the other side of the second connecting member 420, so that the second screw connection hole 422 of the second connecting member 420 is blocked by the first connecting member 410.

[0251] In order to prevent this, a side groove 417 may be provided on a side of the first connecting member 410, which is dug into the inside of the first connecting member 410. The side groove 417 may be a groove that can expose the second screw coupling hole 422 of the second connecting member 420 to the outside when the second connecting member 420 is coupled to the first connecting member 410.

[0252] Since the side groove 417 is provided on the side of the first connecting member 410, even when the first connecting member 410 is connected to the second connecting member 420, the second screw connection hole 422 is prevented from being blocked, and the second connecting member 420 can be connected to the second rod 371 through the second screw connection hole 422.

[0253] The coupling groove 364 according to an embodiment of the present invention includes a circular groove 365 having a circular shape, and an extension groove 366 extending outward from a side surface of the circular groove 365. Also, the coupling protrusion 411 according to an embodiment of the present invention includes a circular protrusion 412 fitted into the circular groove 365, and an extension protrusion 413 extending outward from a side surface of the circular protrusion 412 and fitted into the extension groove 366.

[0254] The circular groove 365 and the circular protrusion 412 are circular in shape, and when the circular protrusion 412 is fitted into the circular groove 365, the central axes of the circular groove 365 and the circular protrusion 412 may coincide. The circular protrusion 412 may have a shape corresponding to the circular groove 365 so as to be fitted into the circular groove 365.

[0255] The extension groove 366 extends outward from a side surface of the circular groove 365, and the extension protrusion 413 extends outward from a side surface of the circular protrusion 412. The extension protrusion 413 may have a shape corresponding to a shape of the extension groove 366 so as to be fitted into the extension groove 366.

[0256] The circular protrusion 412 is sandwiched and fitted into the circular groove 365 , and the extension protrusion 413 is fitted into the extension groove 366 , so that the coupling protrusion 411 can be fitted into the coupling groove 364 .

[0257] When the coupling protrusion 411 is fitted into the coupling 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 removed from the extension groove 366.

[0258] The circular groove 365 and the circular protrusion 412 are circular and have the same central axis, so that the first connecting member 410 can rotate based on the central axis of the circular groove 365 and the circular protrusion 412 .

[0259] 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 is released from the extension groove 366 and the extension protrusion 413 is engaged with the inner side of the coupling groove 364. As a result, the coupling protrusion 411 is prevented from being released from the coupling groove 364.

[0260] That is, the coupling groove 364 and the coupling protrusion 411 according to an embodiment of the present invention allow the first connecting member 410 to rotate smoothly through the circular groove 365 and the circular protrusion 412, which are circular in shape, and when the first connecting member 410 rotates, the coupling protrusion 411 does not come off the coupling groove 364 through the extension protrusion 413 which comes off the extension groove 366.

[0261] According to an embodiment of the present invention, a third rod combination may be coupled to one side of the second connecting part 372 via a rod coupling device 400. When the third rod combination is coupled to one side of the second connecting part 372 via the rod coupling device 400, the second connecting part 372 may have the same structure as the first connecting part 362, and the other side of the third rod may have the same structure as the other side of the second rod 371.

[0262] The system furniture equipped with the rod connector according to the embodiment of the present invention can connect other rod connectors in addition to the third rod connector through the rod connector 400. In this way, the system furniture equipped with the rod connector according to the embodiment of the present invention can install a plurality of rod connectors continuously at the same height through the rod connector 400.

[0263] The rod connecting device 400 used in the system furniture according to an embodiment of the present invention connects the first connecting portion 362 of the first rod connecting body 360 to the other side of the second rod 371 of the second rod connecting body 370 in the system furniture provided with a first rod connecting body 360 including a first rod 361 and a first connecting portion 362, and a second rod connecting body 370 including a second rod 371 and a second connecting portion 372.

[0264] A connecting member 363 having a connecting groove 364 extending in the longitudinal direction is provided on one side of the first connecting portion 362 of the first rod connecting body 360, and the rod connecting device 400 used in the system furniture according to an embodiment of the present invention includes a first connecting member 410 having a connecting protrusion 411 extending in the longitudinal direction and inserted into the connecting groove 364, and a second connecting member 420 connected to the other side of the second rod 371 of the second rod connecting body 370 and to which the first connecting member 410 is rotatably connected, and when the connecting protrusion 411 is inserted into the connecting groove 364 and the first connecting member 410 is rotated, the connecting protrusion 411 may not come off the connecting groove 364.

[0265] The rod connector 400 used in the system furniture according to the embodiment of the present invention is the same as the rod connector 400 included in the system furniture equipped with the rod connector according to the embodiment of the present invention described above, so detailed description will be omitted.

[0266] The system furniture equipped with the rod connecting device according to the embodiment of the present invention described above has the following effects. Since the same or similar configuration as the above-mentioned best embodiment has the same or similar effects, the duplicated description will be omitted.

[0267] The system furniture equipped with the rod connecting device according to the embodiment of the present invention has an advantage that the height of the hanger can be adjusted by selectively connecting the connecting parts of the rod connecting body to a plurality of connecting holes provided in the rail of the pillar and contacting the second electrode provided in the pillar with the third electrode provided in the connecting part of the rod connecting body, thereby enabling electrical connection.

[0268] In addition, the system furniture equipped with the rod connecting device according to the embodiment of the present invention has the advantage that a plurality of rod connecting bodies can be installed continuously at the same height by connecting the first connecting part provided on one side of the first rod connecting body to the other side of the second rod connecting body via the rod connecting device.

[0272] A third embodiment according to yet another aspect of the present invention relates to a system furniture equipped with an electrode bracket device, which allows the height of the shelf to be adjusted, is easy to install and disassemble, and enables electrical connection without using electric wires via the electrode bracket device. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to Figures 1 to 4 and 18 to 23.

[0273] The system furniture equipped with the electrode bracket device according to the embodiment of the present invention includes a base plate 110 , a column 140 , a shelf 160 , and an electrode bracket device 600 .

[0274] The explanation regarding Figs. 1 to 5 applies to the above-mentioned best mode.

[0275] 5 and 24, the hook portion 162 having a hook shape is fitted into the coupling hole 142, thereby coupling the connecting portion 161 to the pillar portion 140. The hook portion 162 may be coupled to one or more of the coupling holes 142.

[0276] According to an embodiment of the present invention, the height at which the connecting portion 161 is connected to the column 140 can be adjusted by changing the positions at which the hook portion 162 is connected to the plurality of connecting holes 142. Thus, the height at which the shelf 160 is connected to the column 140 can be adjusted.

[0277] The support portion 163 of the shelf 160 is provided between the two connecting portions 161. The support portion 163 may have a plate shape, and the support portion 163 may be a support plate of the shelf 160.

[0278] Referring to FIG. 25, the electrode bracket device 600 is provided on the connecting portion 161 , and the electrode bracket device 600 is a bracket for mounting a connection electrode 630 on the connecting portion 161 .

[0279] The electrode bracket device 600 includes a housing 610 , a substrate 620 , a connecting electrode 630 , and a pogo pin 640 .

[0280] 25 and 26, the housing 610 is provided with a hook housing 611 that protrudes outward from the connecting portion 161 so as to be fitted into the connecting hole 142 of the rail 141, and is connected to the connecting portion 161.

[0281] The housing 610 may be coupled to the connecting portion 161 , and when the housing 610 is coupled to the connecting portion 161 , a portion protruding outward from the connecting portion 161 may be the hook housing 611 .

[0282] The hook housing 611 may have a shape corresponding to the hook portion 162 , and the hook housing 611 may be fitted into the coupling hole 142 of the rail 141 .

[0283] As described above, the hook portion 162 of the connecting portion 161 can be fitted into the coupling hole 142 to connect the connecting portion 161 to the column portion 140 .

[0284] The hook housing 611 may be substituted for any one of the plurality of hook portions 162 provided on the connecting portion 161. According to an embodiment of the present invention, any one of the plurality of hook portions 162 provided for connecting the connecting portion 161 to the pillar portion 140 may be substituted for the hook housing 611.

[0285] 26 and 27, the hook housing 611 may be provided with a connection electrode 630. The hook housing 611 may be provided with a pair of the connection electrodes 630, and the hook housing 611 may be provided with the connection electrode 630 consisting of an anode and the connection electrode 630 consisting of a cathode.

[0286] The hook housing 611 according to the embodiment of the present invention is provided with a pair of connection electrodes 630 each consisting of a cathode and an anode. By providing the pair of connection electrodes 630 each consisting of a cathode and an anode in the hook housing 611, the connection electrodes 630 and the second electrode 150 can be electrically connected to each other while minimizing electrode exposure.

[0287] Specifically, when the connection part 161 is coupled to the column part 140, the hook housing 611 is fitted into the coupling hole 142 of the rail 141 to bring the second electrode 150 into contact with the connection electrode 630. The connection electrode 630 may be a pair of electrodes including a cathode and an anode, and the pair of connection electrodes 630 may be provided on one hook housing 611.

[0288] When the hook housing 611 is fitted into the coupling hole 142 of the rail 141, the cathode of the connection electrode 630 may be in contact with the cathode of the second electrode 150, and the anode of the connection electrode 630 may be in contact with the anode of the second electrode 150. Thus, the second electrode 150 and the connection electrode 630 are electrically connected to each other.

[0289] As described above, the second electrode 150 is made of a thin film and extends along the height direction of the pillar 140. Therefore, no matter at what height the shelf 160 is coupled to the pillar 140, the second electrode 150 and the connection electrode 630 can come into contact with each other and be electrically connected to each other.

[0290] According to an embodiment of the present invention, the connection electrode 630 may include a connection electrode connection portion 171 that is bent and protrudes outward from the hook housing 611. Referring to FIG 28, the connection electrode connection portion 631 may be bent and protrude outward from the hook portion 162.

[0291] When the hook housing 611 is fitted into the connection hole 142 of the rail 141, the connection electrode connection portion 631 protruding from the hook housing 611 comes into contact with the second electrode 150, so that the connection electrode 630 and the second electrode 150 are electrically connected.

[0292] Here, the connection electrode connector 631 may include a cathode and an anode. When the connection electrode connector 631 is in contact with the second electrode 150 made of a thin film, the cathode of the second electrode 150 may be in contact with the cathode of the connection electrode connector 631, and the anode of the second electrode 150 may be in contact with the anode of the connection electrode connector 631.

[0293] In this manner, the system furniture equipped with the electrode bracket device according to an embodiment of the present invention can electrically connect the second electrode 150 and the connection electrode 630 simply by connecting or assembling the hook portion 162 and the hook housing 611 of the shelf 160 to the pillar portion 140.

[0294] According to an embodiment of the present invention, the second electrode 150 is made of a thin film extending along the height direction of the pillar 140, so that the connection electrode 630 and the second electrode 150 can come into contact with each other and be electrically connected regardless of the height at which the hook housing 611 is attached to the pillar 140.

[0295] That is, the second electrode 150 and the connection electrode 630 come into contact with each other and are electrically connected to each other regardless of where the hook portion 162 and the hook housing 611 are fitted and coupled to each other in the coupling holes 142. As a result, even if the height at which the shelf 160 is installed with respect to the column portion 140 is adjusted, the second electrode 150 and the connection electrode 630 come into contact with each other and are electrically connected to each other.

[0296] According to an embodiment of the present invention, the connection electrode connection portion 631 may be made of an elastic material, and the connection electrode connection portion 631 may be in an outwardly expanded state before the hook housing 611 is fitted into the coupling hole 142.

[0297] When the hook housing 611 is fitted into the coupling hole 142, the connection electrode connection portion 631 extending outward is gathered inward by the pillar portion 140. That is, the connection electrode connection portion 631 extending outward of the hook housing 611 can be forcibly fitted into the inner side of the pillar portion 140 through the coupling hole 142 while gathering the connection electrode connection portion 631 extending outward of the hook housing 611 inward.

[0298] When the connection electrode connection portion 631 is gathered inward by the pillar portion 140, an elastic restoring force is generated in the connection electrode connection portion 631 made of an elastic member. When the hook housing 2110 is fitted into the coupling hole 142, the connection electrode connection portion 631 may be elastically pressed to expand outward by the elastic restoring force.

[0299] In this manner, when the hook housing 611 is fitted into the coupling hole 142, the connection electrode connection portion 631 is elastically pressed to expand outward, thereby allowing the connection electrode connection portion 631 to be firmly in contact with the second electrode 150.

[0300] 26 and 28, the substrate 620 is provided inside the housing 610, and the connection electrode 630 may be connected to one side of the substrate 620. An electric circuit may be provided inside the substrate 620, and the pogo pin 640 may be provided on the other side of the substrate 620.

[0301] The pogo pins 640 are protruded to the outside of the housing 610 and provided on the other side of the board 620. The pogo pins 640 may be provided in pairs and may protrude to the outside of the housing 610.

[0302] According to an embodiment of the present invention, the connection electrode 630 and the pogo pin 640 may be electrically connected to each other via the substrate 620. Specifically, the connection electrode 630 and the pogo pin 640 may be electrically connected to each other via an electric circuit provided on the substrate 620.

[0303] The electrode bracket device 600 may be provided with a pair of the connection electrodes 630 and the pogo pins 640, and the connection electrode 630 consisting of an anode is connected to one of the pogo pins 640 via the substrate 620, and the connection electrode 630 consisting of a cathode is connected to the other pogo pin 640 via the substrate 620.

[0304] Referring to FIG. 29, an electrode bracket device 600 according to an embodiment of the present invention enables electrical connection between the connection electrode 630 and the pogo pin 640 without using wires by connecting the connection electrode 630 and the pogo pin 640 via the substrate 620.

[0305] If an electric wire is used to connect the connection electrode 630 and the pogo pin 640, there is a risk that the electric wire may break inside the connecting part 161. If the electric wire breaks inside the connecting part 161, causing an electrical short circuit, there is a problem that it is difficult to find the location of the electrical short circuit, and it is difficult to repair the broken electric wire.

[0306] The electrode bracket device 600 according to an embodiment of the present invention does not require wires by connecting the connection electrode 630 and the pogo pin 640 via the substrate 620, which has the advantage of preventing disconnection and making it easy to find electrical shorts.

[0307] 30, the pogo pin 640 may be in contact with a contact terminal 564 provided on a side surface of the support portion 163 of the shelf 160. The contact terminal 564 is in contact with the pogo pin 640 to be electrically connected. When the pogo pin 640 and the contact terminal 564 are connected, electricity supplied via the connection electrode 630 is transferred to the contact terminal 564.

[0308] The contact terminal 564 is connected to various electrical devices such as the lighting 180 provided inside the shelf 160, and electricity can be supplied to the various electrical devices provided inside the shelf 160 via the contact terminal 564.

[0309] A system furniture equipped with an electrode bracket device according to an embodiment of the present invention may include a light 180 provided on the shelf 160 and connected to the connection electrode 630. The light 180 is electrically connected to the connection electrode 630, and the light 180 may be provided at various points on the shelf 160.

[0310] The light 180 is electrically connected to the contact terminal 564, and may be electrically connected to the connection electrode 630 via the pogo pin 640. The light 180 may be in the form of a diffusion plate. However, the light 180 is not limited thereto, and may be provided on the shelf 160 in various forms.

[0311] The first electrode 130 provided on the connecting bracket 120 is supplied with electricity through the electrical connection line 121, and the electricity supplied to the first electrode 130 is transferred to the second electrode 150. The electricity transferred to the second electrode 150 is transferred to a connection electrode 630, and the electricity transferred to the connection electrode 630 is transferred to the contact terminal 564 via the substrate 620 and the pogo pin 640. The electricity transferred to the contact terminal 564 is transferred to the light 180, and light is emitted from the light 180.

[0312] 29 and 31, the electrode bracket device 600 according to an embodiment of the present invention is provided inside the hook housing 611 and includes a first support part 650 and a second support part 660 for supporting one of the connection electrode connection parts 631.

[0313] As described above, the connection electrode connection portion 631 protrudes outward from the hook housing 611, and the connection electrode connection portion 631 may be in an outwardly expanded state before the hook housing 611 is fitted into the coupling hole 142.

[0314] The connection electrode connection portion 631, which spreads out outside the hook housing 611, is gathered inward and the connection electrode connection portion 631 is forcibly fitted through the coupling hole 142, thereby making firm contact between the connection electrode connection portion 631 and the second electrode 150.

[0315] According to an embodiment of the present invention, since the connection electrode connection portion 631 is made of an elastic material, when the hook housing 611 is separated from the coupling hole 142, the connection electrode connection portion 631 returns to a shape protruding outside the hook housing 611.

[0316] However, if the connection electrode connection portion 631 is used repeatedly or if the connection electrode connection portion 631 is forcibly fitted into the connection hole 142 and coupled for a long period of time, there is a risk that elastic deformation will occur in the connection electrode connection portion 631.

[0317] If elastic deformation occurs in the connection electrode connection part 631, even if the hook housing 611 is separated from the coupling hole 142, the connection electrode connection part 631 may not return to a shape protruding outward from the hook housing 611. As a result, there is a risk that the connection electrode connection part 631 and the second electrode 150 may not be firmly in contact with each other when the connecting part 161 is reused.

[0318] The first supporting part 650 and the second supporting part 660 may be members for preventing this. Referring to Fig. 31, the first supporting part 650 includes a first upward inclined part 651 formed on the substrate 620 with an upward inclination toward the hook housing 611, and a first downward inclined part 652 formed on the substrate 620 with a downward inclination toward the hook housing 611.

[0319] Referring to FIG. 29, one of the pair of connection electrode connection portions 631 includes an upward inclination and a downward inclination, and the point where the upward inclination and the downward inclination intersect may protrude outside the hook housing 611.

[0320] The first supporting portion 650 may have a shape corresponding to a shape of the connection electrode connecting portion 631. Referring to Fig. 29, the first upwardly inclined portion 651 of the first supporting portion 650 supports the upward inclination of the connection electrode connecting portion 631, and the first downwardly inclined portion 652 of the first supporting portion 650 supports the downward inclination of the connection electrode connecting portion 631.

[0321] According to an embodiment of the present invention, by supporting the connection electrode connection portion 631 via the first support portion 650, even if elastic deformation occurs in the connection electrode connection portion 631, the connection electrode connection portion 631 can be protruded outside the hook housing 611.

[0322] Specifically, since the first support portion 650 has a shape corresponding to one of the connection electrode connection portions 631, even if elastic deformation occurs in the connection electrode connection portion 631, the shape of the first support portion 650 may cause the connection electrode connection portion 631 to protrude outside the hook housing 611.

[0323] Therefore, when the hook housing 611 is separated from the coupling hole 142 , the connection electrode connecting portion 631 returns to a state in which it protrudes outward from the hook housing 611 .

[0324] 31, the second support part 660 includes a second downwardly inclined part 661 that is inclined downward toward the hook housing 611 on the substrate 620. Referring to FIG. 29, the other of the pair of connection electrode connection parts 631 includes a downward inclination and an upward inclination, and a point where the downward inclination and the upward inclination intersect may protrude outside the hook housing 611.

[0325] The second support portion 660 may have a shape corresponding to the downward inclination of the connection electrode connection portion 631, and referring to FIG. 29, the second downward inclination portion 661 of the second support portion 660 supports the downward inclination of the connection electrode connection portion 631.

[0326] According to an embodiment of the present invention, by supporting the connection electrode connection portion 631 via the second support portion 660, even if elastic deformation occurs in the connection electrode connection portion 631, the connection electrode connection portion 631 can be protruded outside the hook housing 611.

[0327] Specifically, since the second support portion 660 has a shape corresponding to the connection electrode connection portion 631, even if elastic deformation occurs in the connection electrode connection portion 631, the shape of the second support portion 660 may cause the connection electrode connection portion 631 to protrude outside the hook housing 611.

[0328] Therefore, when the hook housing 611 is separated from the coupling hole 142 , the connection electrode connecting portion 631 returns to a state in which it protrudes outward from the hook housing 611 .

[0329] 28 and 29, the first support 650 and the second support 660 are provided on the housing 610 and may be fixedly installed on a connection housing 612 coupled to the housing 610 .

[0330] In this case, the first support part 650 and the second support part 660 may be disposed inside the hook housing 611 protruding outward from the connecting part 161, or may be fixedly coupled to the housing 610 via the connecting housing 612.
