[0154] Specifically, when the switch 220 is pressed in a state in which the sliding portion 230 does not protrude outward from the housing 210, the switch 220 is moved upward and the path guide portion 260 is moved downward along one surface 222 of the switch 220.

[0155] When the path guide portion 260 is moved downward along one surface 222 of the switch 220, the path guide portion 260 is moved to the first path 223 along the first upper downward slope 271 of the first path guide projection 270.

[0156] When the path guide portion 260 is moved along the first path 223, the path guide portion 260 comes into contact with the upward slope 281 of the second path guide projection 280 provided below the first path 223 and is disposed at the lower portion between the first lower downward slope 273 and the second lower downward slope 274 of the first path guide projection 270.

[0157] 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 is moved downward and the path guide portion 260 is moved upward, so that the path guide portion 260 is caught between the first lower downward slope 273 and the second lower downward slope 274 of the first path guide projection 270.

[0158] As the path guide portion 260 is caught between the first lower downward slope 273 and the second lower downward slope 274 of the first path guide projection 270, the moving projection 221 of the switch 220 may be maintained in a state of being stopped at the upper point of the moving groove 241. When the moving projection 221 of the switch 220 is maintained in a state of being stopped at the upper point of the moving groove 241, the sliding portion 230 may be in a state of protruding outward from the housing 210.

[0159] Referring to FIGS. 15(b) and (b), when the switch 220 is pressed again in a state in which the sliding portion 230 protrudes outward from the housing 210, the path guide portion 260 is moved along the second path 224.

[0160] Specifically, when the switch 220 is pressed again in a state in which the sliding portion 230 protrudes outward from the housing 210, the switch 220 is moved upward and the path guide portion 260 is moved downward along one surface 222 of the switch 220.

[0161] When the path guide portion 260 is moved downward along one surface 222 of the switch 220, the path guide portion 260 comes into contact with the downward slope 291 of the third path guide projection 290 and is moved to the second path 224 away from between the first lower downward slope 273 and the second lower downward slope 274 of the first path guide projection 270.

[0162] When the force pressing the switch 220 is removed, the switch 220 is moved downward by the force of the spring 250 and the path guide portion 260 is moved upward.

[0163] At this time, since the path guide portion 260 is moved to the second path 224 away from between the first lower downward slope 273 and the second lower downward slope 274 of the first path guide projection 270, the path guide portion 260 is moved upward along the second path 224.

[0164] The path guide portion 260 moved upward along the second path 224 may come into contact with the second upper downward slope 272 of the first path guide projection 270. Accordingly, the path guide portion 260 returns to the initial position in which the sliding portion 230 does not protrude outward from the housing 210.

[0165] As described above, when the switch 220 is pressed once, the moving projection 221 of the switch 220 may be maintained in a state of being stopped at the upper point of the moving groove 241 through the path guide portion 260. In addition, when the switch 220 is pressed again, the moving projection 221 of the switch 220 may be disposed again below the moving groove 241.

[0166] According to an embodiment of the present disclosure, when the moving projection 221 of the switch 220 may be maintained in a state of being stopped at the upper point of the moving groove 241, the sliding portion 230 is maintained in a state of protruding outward from the housing 210. In addition, when the moving projection 221 of the switch 220 is disposed below the moving groove 241, the sliding portion 230 may not protrude outward from the housing 210.

[0167] In this manner, the system furniture provided with the shelf fixing device, according to an embodiment of the present disclosure, may slidingly move the sliding portion 230 in a state of protruding or not protruding outward from the housing 210 by the operations of the path guide portion 260 and the switch 220.

[0168] According to an embodiment of the present disclosure, 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 in which one side of the sliding portion 230 is chamfered.

[0169] When one side of the sliding portion 230 is chamfered, the frictional force generated between the sliding portion 230 and the fixing portion 240 is reduced, and thus, the sliding portion 230 is slidingly moved smoothly.

[0170] Referring to FIGS. 3 and 4, the pillar portion 140 according to an embodiment of the present disclosure may be provided with a wing portion 143 protruding outward from the pillar portion 140.

[0187] On the other hand, embodiments according to other aspects of the present disclosure are presented. In the second and third embodiments presented below, the description of the same or similar configuration as that of the preceding best mode is applied identically or with appropriate changes and a redundant description thereof is omitted.

[0188] The second embodiment relates to a system furniture provided with a rod connection device, which is capable of adjusting the height of a hanger while allowing electrical connection, making it easy to install and dismantle the hanger, and continuously installing a plurality of hangers at the same height. Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to FIGS. 1 to 4 and 18 to 23.

[0189] A system furniture provided with a rod connection device, according to an embodiment of the present disclosure, includes a bottom plate 110, a pillar portion 140, a first rod assembly 360, a second rod assembly 370, and a rod connection device 400.

[0190] Referring to FIGS. 17 and 2, the bottom plate 110 may be formed in a plate shape and the bottom plate 110 may be a lower plate of the system furniture. The bottom plate 110 may be provided in plurality and bottom plate 110 may be installed on the ground.

[0191] The above description of the best mode is applied to the description of FIGS. 2 to 4.

[0192] Referring to FIG. 18, the first rod assembly 360 and the second rod assembly 370 are coupled to the pillar portion 140. The first rod assembly 360 and the second rod assembly 370 may be hangers coupled to the system furniture.

[0193] The first rod assembly 360 includes a first rod 361 formed in a rod shape and a first connecting portion 362 provided on one side of the first rod 361 and provided with a plurality of hook portions 380 formed in a hook shape so as to be fitted into the coupling holes 142 of the rail 141.

[0194] The second rod assembly 370 includes a second rod 371 formed in a rod shape and a second connecting portion 372 provided on one side of the second rod 371 and provided with a plurality of hook portions 380 formed in a hook shape so as to be fitted into the coupling holes 142 of the rail 141.

[0195] The first rod 361 and the second rod 371 may be rods on which clothes hangers, clothes, etc. may be hung. The first connecting portion 362 and the second connecting portion 372 may be coupled to the pillar portion 140 so as to install the first rod 361 and the second rod 371.

[0196] The first connecting portion 362 and the second connecting portion 372 may be formed as cantilevers, and the plurality of hook portions 380 formed in a hook shape may be provided on one side of each of the first connecting portion 362 and the second connecting portion 372.

[0197] Referring to FIGS. 3 and 19, the first connecting portion 362 and the second connecting portion 372 may be coupled to the pillar portion 140 by fitting the hook portion 380 formed in a hook shape into the coupling hole 142. The hook portion 380 may be coupled to one or more of the plurality of coupling holes 142.

[0198] According to an embodiment of the present disclosure, the heights at which the first connecting portion 362 and the second connecting portion 372 are coupled to the pillar portion 140 may be adjusted by changing the position at which the hook portion 380 is coupled to the plurality of coupling holes 142. In this manner, the heights at which the first rod assembly 360 and the second rod assembly 370 are coupled to the pillar portion 140 may be adjusted.

[0199] The system furniture provided with the rod connection device, according to an embodiment of the present disclosure, may further include a third electrode 381. The third electrode 381 is provided in the first connecting portion 362 and the second connecting portion 372. When the first connecting portion 362 and the second connecting portion 372 are connected to the pillar portion 140, the third electrode 381 comes into contact with the second electrode 150. The third electrode 381 may include a pair of electrodes including a negative electrode and a positive electrode.

[0200] When the first connecting portion 362 and the second connecting portion 372 are coupled to the pillar portion 140, the negative electrode of the third electrode 381 may come into contact with the negative electrode of the second electrode 150 and the positive electrode of the third electrode 381 may come into contact with the positive electrode of the second electrode 150. In this manner, the second electrode 150 and the third electrode 381 may be electrically connected to each other.

[0201] As described above, the second electrode 150 is made of a thin-film and extends along the height direction of the pillar portion 140. Accordingly, regardless of the height at which the first rod assembly 360 and the second rod assembly 370 are coupled to the pillar portion 140, the second electrode 150 and the third electrode 381 may be electrically connected to each other by coming into contact with each other.

[0202] According to an embodiment of the present disclosure, the third electrode 381 may be provided in the first connecting portion 362 and the second connecting portion 372. The third electrode 381 may be provided in the hook portions 380 of the first connecting portion 362 and the second connecting portion 372.

[0203] The third electrode 381 may include a third electrode connecting portion 382 that protrudes outward from the hook portion 380 while being bent. Referring to FIG. 7, the third electrode connecting portion 382 may protrude outward from the hook portion 380 while being bent.

[0204] As described above, the second electrode 150 may be made of a thin-film that is provided inside the pillar portion 140 and extends along the height direction of the pillar portion 140. When the hook portion 380 is fitted into the coupling hole 142 of the rail 141, the third electrode connecting portion 382 protruding from the hook portion 380 may come into contact with the second electrode 150, so that the third electrode 381 and the second electrode 150 may be electrically connected to each other.

[0205] Here, the third electrode connecting portion 382 may include a negative electrode and a positive electrode. When the third electrode connecting portion 382 comes into contact with the second electrode 150 made of the thin-film, the negative electrode of the second electrode 150 may come into contact with the negative electrode of the third electrode connecting portion 382 and the positive electrode of the second electrode 150 may come into contact with the positive electrode of the third electrode connecting portion 382.

[0206] In this manner, the system furniture provided with the rod connection device, according to an embodiment of the present disclosure, may electrically connect the second electrode 150 to the third electrode 381 simply by a process of coupling or assembling the hook portions 380 of the first connecting portion 362 and the second connecting portion 372 to the pillar portion 140.

[0207] Referring to FIGS. 4 and 20, since the second electrode 150 according to an embodiment of the present disclosure is made of a thin-film extending along the height direction of the pillar portion 140, the third electrode 381 and the second electrode 150 may be electrically connected to each other by coming into contact with each other, regardless of the height at which the hook portion 380 is coupled to the pillar portion 140.

[0208] That is, regardless of the position at which the hook portion 380 is fitted into and coupled to the plurality of coupling holes 142, the second electrode 150 and the third electrode 381 may be electrically connected to each other by coming into contact with each other. In this manner, even when the height at which the first rod assembly 360 and the second rod assembly 370 are installed is adjusted with respect to the pillar portion 140, the second electrode 150 and the third electrode 381 may be electrically connected to each other by coming into contact with each other.

[0209] According to an embodiment of the present disclosure, the third electrode connecting portion 382 may be made of an elastic member and, before the hook portion 162 is fitted into the coupling hole 142, the third electrode connecting portion 382 may be in a state of being spread outward.

[0210] Referring to FIG. 20, when the hook portion 380 is fitted into the coupling hole 142, the third electrode connecting portion 382 spread outward may be gathered inward by the pillar portion 140. That is, the hook portion 380 may be press-fitted to the inner side of the pillar portion 140 through the coupling hole 142 while the third electrode connecting portion 382 spread outward is gathered inward.

[0211] When the third electrode connecting portion 382 is gathered inward by the pillar portion 140, an elastic restoring force is generated in the third electrode connecting portion 382 made of an elastic member. When the hook portion 380 is fitted into the coupling hole 142, the third electrode connecting portion 382 may be elastically pressurized to be spread outward by the elastic restoring force.

[0212] In this manner, when the hook portion 380 is fitted into the coupling hole 142, the third electrode connecting portion 382 may be brought into firm contact with the second electrode 150 by elastically pressurizing the third electrode connecting portion 382 to be spread outward.

[0213] The system furniture provided with the rod connection device, according to an embodiment of the present disclosure, may include a lamp 392 provided on at least one of the first rod 361 and the second rod 371.

[0214] The lamp 392 is electrically connected to the third electrode 381. The lamp 392 may be provided at various points of the first rod 361 and the second rod 371. The lamp 392 may be connected to the third electrode 381 through a wire or other electrical connection device and the lamp 392 may be formed in the form of a diffusion plate. However, the present disclosure is not limited thereto and the lamp 392 may be provided on the first rod 361 and the second rod 371 in various forms.

[0215] The first electrode 130 provided in the connecting bracket 120 is supplied with electricity through the electrical connection line 121 and the electricity supplied to the first electrode 130 is transmitted to the second electrode 150. The electricity transmitted to the second electrode 150 is transmitted to the third electrode 381 and the electricity transmitted to the third electrode 381 is transmitted to the lamp 392, so that light may be emitted from the lamp 392.

[0216] According to an embodiment of the present disclosure, the first connecting portion 362 may be provided on both one side and the other side of the first rod assembly 360, or the first connecting portion 362 may be provided on only one side of the first rod assembly 360.

[0217] According to an embodiment of the present disclosure, the second connecting portion 372 may be provided on only one side of the second rod assembly 370, and the other side of the second connecting portion 372 may be opened in a state in which the second connecting portion 372 is not provided.

[0218] In a case where the first rod assembly 360 and the second rod assembly 370 are coupled to the pillar portion 140, when the second connecting portion 372 is provided on both one side and the other side of the second rod assembly 370, the first rod assembly 360 and the second rod assembly 370 may not be installed continuously at the same height.

[0219] Specifically, in a case where the first rod assembly 360 and the second rod assembly 370 are installed continuously at the same height in the system furniture, when the second connecting portion 372 is provided on both one side and the other side of the second rod assembly 370, interference occurs between the first connecting portion 362 provided on one side of the first rod assembly 360 and the second connecting portion 372 provided on the other side of the second rod assembly 370.

[0220] More specifically, only one of the first connecting portion 362 provided on one side of the first rod assembly 360 and the second connecting portion 372 provided on the other side of the second rod assembly 370 is fitted into the rail 141 provided on the pillar portion 140. Accordingly, when the second connecting portion 372 is provided on both one side and the other side of the second rod assembly 370, the first rod assembly 360 and the second rod assembly 370 may not be installed continuously at the same height.

[0221] Of course, a plurality of rails 141 may be installed on the pillar portion 140 so that the first connecting portion 362 provided on one side of the first rod assembly 360 and the second connecting portion 372 provided on the other side of the second rod assembly 370 may be respectively coupled to the rails 141. However, when the plurality of rails 141 are installed on the pillar portion 140 as described above, the volume of the system furniture increases, which is not aesthetically pleasing.

[0222] To solve this problem, the system furniture provided with the rod connection device, according to an embodiment of the present disclosure, may use the rod connection device 400. The rod connection device 400 connects the first connecting portion 362 of the first rod assembly 360 to the other side of the second rod 371 of the second rod assembly 370.

[0223] The rod connection device 400 includes a first connecting member 410 and a second connecting member 420. Referring to FIGS. 19 and 20, a coupling member 363 having a coupling groove 364 extending in the longitudinal direction may be provided on one side of the first connecting portion 362 of the first rod assembly 360.

[0224] The coupling member 363 is coupled to the 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 the longitudinal direction or in one direction and a coupling projection 411 to be described below may be inserted into the coupling groove 364.

[0225] According to an embodiment of the present disclosure, the coupling member 363 may be formed as a member separate from the first connecting portion 362 and may be coupled to the side surface of the first connecting portion 362, and the coupling member 363 may also be integrally formed with the first connecting portion 362.

[0226] The first connecting member 410 is provided with the coupling projection 411 that extends in the longitudinal direction and is inserted into the coupling groove 364. The coupling projection 411 is a projection extending in the longitudinal direction or in one direction and the coupling projection 411 may protrude outward from the first connecting member 410.

[0227] The coupling projection 411 may be formed in 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 disclosure, when the coupling projection 411 is inserted into the coupling groove 364 and the first connecting member 410 is rotated, the coupling projection 411 may not be released from the coupling groove 364.

[0228] Specifically, referring to FIGS. 20 and 21, an empty space is formed inside the coupling member 363. When the coupling projection 411 is inserted into the coupling groove 364 of the coupling member 363, the coupling projection 411 may be rotated through the empty space inside the coupling member 363.

[0229] Since the coupling projection 411 is formed in a shape corresponding to the shape of the coupling groove 364 so as to be fitted into the coupling groove 364, the coupling projection 411 is caught on the outside of the coupling groove 364 the coupling projection 411 is rotated, and thus, the coupling projection 411 may not be released from the coupling groove 364.

[0230] 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.

[0231] Referring to FIGS. 21, 22(a), and 22(b), a circular through hole 421 passing through the second connecting member 420 may be provided inside the second connecting member 420. A rotating projection 415 corresponding to the shape of the through hole 421 may be provided inside the first connecting member 410 so as to be fitted into the through hole 421.

[0232] A first screw coupling hole 416 into which a screw 430 is inserted may be provided inside the rotating projection 415 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.

[0233] When the screw 430 is coupled to the first screw coupling hole 416 in a state in which the rotating projection 415 of the first connecting member 410 is inserted into the through hole 421 of the second connecting member 420, the first connecting member 410 may be rotatably coupled to the second connecting member 420.

[0234] At this time, a bearing 431 may be provided between the screw 430 and the through hole 421. The bearing 431 is intended to prevent the screw 430 from coming into contact with and being fixed to the second connecting member 420.

[0235] When the bearing 431 is not present, the screw 430 may come into contact with the second connecting member 420. When the screw 430 comes into contact with the second connecting member 420 and the first connecting member 410 is rotated, a frictional force is generated between the screw 430 and the second connecting member 420 and the rotation of the first connecting member 410 may be limited by the frictional force.

[0236] Here, since the screw 430 is coupled to the first screw coupling hole 416 of the first connecting member 410, the screw 430 is rotated together with the first connecting member 410.

[0237] When the bearing 431 is provided between the screw 430 and the through hole 421, the screw 430 may be prevented from coming into contact with the second connecting member 420, and thus, the first connecting member 410 may be smoothly rotated with respect to the second connecting member 420.

[0238] According to an embodiment of the present disclosure, the first connecting member 410 may be provided with a handle 414 protruding outward from the first connecting member 410. Referring to FIGS. 22(a) and 22(b), the handle 414 protrudes outward from the first connecting member 410, and the first connecting member 410 may be rotated with respect to the second connecting member 420 by applying a force to the first connecting member 410 through the handle 414.

[0239] According to an embodiment of the present disclosure, a rotation limiting projection 423 protruding outward while extending along the circumferential direction of the second connecting member 420 may be provided on one surface of the second connecting member 420. The rotation limiting projection 423 may extend along the circumferential direction of the second connecting member 420 by a specified angle, based on the center of the second connecting member 420.

[0240] The rotation limiting projection 423 may limit the rotation of the first connecting member 410. Referring to FIGS. 22(a) and 22(b), the handle 414 of the first connecting member 410 may protrude outward at a point where the rotation limiting projection 423 is not provided. The handle 414 may be rotated only at the point where the rotation limiting projection 423 is not provided.

[0241] Specifically, a point where the rotation limiting projection 423 is provided along the circumferential direction and a point where the rotation limiting projection 423 is not provided are present on one surface of the second connecting member 420. The handle 414 of the first connecting member 410 may protrude outward at the point where the rotation limiting projection 423 is not provided. When the handle 414 is rotated, the handle 414 may come into contact with the rotation limiting projection 423.

[0242] When the handle 414 comes into contact with the rotation limiting projection 423, the rotation of the handle 414 may be limited by the rotation limiting projection 423. That is, the first connecting member 410 may be rotated only at the point of the second connecting member 420 where the rotation limiting projection 423 is not provided and the rotation angle of the first connecting member 410 may be limited by the rotation limiting projection 423.

[0243] The rod connection device 400 according to an embodiment of the present disclosure may be installed in the following method.

[0244] Referring to FIGS. 22(a) and 22(b), the first connecting member 410 and the second connecting member 420 may be first coupled to each other through the screw 430 and the bearing 431. The second connecting member 420 may be coupled to the other side of the second rod 371. When 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 may be blocked by the second rod 371.

[0245] The screw 430 has to be connected to the first connecting member 410 by passing through the through hole 421 on one side of the second connecting member 420. However, when the second connecting member 420 is first connected to the other side of the second rod 371, there is no space for inserting the screw 430 due to the second rod 371. Therefore, it is preferable to first couple the first connecting member 410 to the second connecting member 420 through the screw 430 and the bearing 431.

[0246] After the first connecting member 410 is coupled to the second connecting member 420, 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 passing through the second connecting member 420, and a screw coupling hole 373 into which a screw may be fitted is provided inside the second rod 371.

[0247] When the screw is inserted into the screw coupling hole 373 of the second rod 371 by passing through the second screw coupling hole 422 on the other side of the second connecting member 420, the second connecting member 420 is coupled to the other side of the second rod 371 in a state in which the first connecting member 410 is coupled to the second connecting member 420, as illustrated in FIG. 23.

[0248] Thereafter, when the coupling projection 411 provided in the first connecting member 410 is inserted into the coupling groove 364 and the first connecting member 410 is rotated through the handle 414, the coupling projection 411 may be prevented from being released from the coupling groove 364.

[0249] Since the coupling projection 411 is not released from the coupling groove 364, the first connecting portion 362 of the first rod assembly 360 may be coupled to the other side of the second rod 371.

[0250] In this manner, in the system furniture provided with the rod connection device, according to the embodiment of the present disclosure, the first rod assembly 360 and the second rod assembly 370 may be installed at the same height through the rod connection device 400 even when the second connecting portion 372 is not provided on the other side of the second rod 371.

[0251] According to an embodiment of the present disclosure, a side groove 417 recessed inward from the first connecting member 410 may be provided on the side surface of the first connecting member 410. After the first connecting member 410 is first coupled to the second connecting member 420 as described above, the second connecting member 420 is coupled to the second rod 371.

[0252] Referring to FIGS. 22(a), 22(b), and 23, since the first connecting member 410 is disposed on the other side of the second connecting member 420, the second screw coupling hole 422 of the second connecting member 420 may be blocked by the first connecting member 410.

[0253] To solve this problem, the side groove 417 recessed inward from the first connecting member 410 may be provided on the side surface of the first connecting member 410. When the first connecting member 410 is coupled to the second connecting member 420, the side groove 417 may be a groove that may expose the second screw coupling hole 422 of the second connecting member 420 to the outside.

[0254] Since the side groove 417 is provided on the side surface of the first connecting member 410, the second screw coupling hole 422 is prevented from being blocked even when the first connecting member 410 is coupled to the second connecting member 420, and the second connecting member 420 may be coupled to the second rod 371 through the second screw coupling hole 422.

[0255] The coupling groove 364 according to an embodiment of the present disclosure includes a circular groove 365 formed in a circular shape and an extension groove 366 extending outward from the side surface of the circular groove 365. In addition, the coupling projection 411 according to the embodiment of the present disclosure includes a circular projection 412 fitted into the circular groove 365 and an extension projection 413 extending outward from the side surface of the circular projection 412 and fitted into the extension groove 366.

[0256] The circular groove 365 and the circular projection 412 are formed in a circular shape. When the circular projection 412 is fitted into the circular groove 365, the central axes of the circular groove 365 and the circular projection 412 may coincide with each other. The circular projection 412 may be formed in a shape corresponding to the shape of the circular groove 365 so as to be fitted into the circular groove 365.

[0257] The extension groove 366 extends outward from the side surface of the circular groove 365 and the extension projection 413 extends outward from the side surface of the circular projection 412. The extension projection 413 may be formed in a shape corresponding to the shape of the extension groove 366 so as to be fitted into the extension groove 366.

[0258] By fitting the circular projection 412 into the circular groove 365 and fitting the extension projection 413 into the extension groove 366, the coupling projection 411 may be fitted into the coupling groove 364.

[0259] When the coupling projection 411 is fitted into the coupling groove 364 and the first connecting member 410 is rotated, the circular projection 412 may be maintained in a state of being inserted into the circular groove 365 and the extension projection 413 may be released from the extension groove 366.

[0260] Since the circular groove 365 and the circular projection 412 are formed in a circular shape and the central axes thereof coincide with each other, the first connecting member 410 may be rotated with respect to the central axes of the circular groove 365 and the circular projection 412.

[0261] When the first connecting member 410 is rotated with respect to the central axes of the circular groove 365 and the circular projection 412, the extension projection 413 is released from the extension groove 366 and the extension projection 413 is caught inside the coupling groove 364. This prevents the coupling projection 411 from being released the coupling groove 364.

[0262] That is, the coupling groove 364 and the coupling projection 411 according to an embodiment of the present disclosure may smoothly rotate the first connecting member 410 through the circular groove 365 and the circular projection 412 formed in a circular shape, and the coupling projection 411 may be prevented from being released from the coupling groove 364 through the extension projection 413 that is released from the extension groove 366 when the first connecting member 410 is rotated.

[0263] According to an embodiment of the present disclosure, a third rod assembly may be coupled to one side of the second connecting portion 372 through the rod connection device 400. When the third rod assembly is coupled to one side of the second connecting portion 372 through the rod connection device 400, the second connecting portion 372 may have the same structure as the first connecting portion 362 and the other side of the third rod may have the same structure as the other side of the second rod 371.

[0264] In the system furniture provided with the rod connection device, according to an embodiment of the present disclosure, another rod assembly in addition to the third rod assembly may be coupled through the rod connection device 400. As described above, in the system furniture provided with the rod connection device, according to an embodiment of the present disclosure, a plurality of rod assemblies may be installed continuously at the same height through the rod connection device 400.

[0265] The rod connection device 400 for use in the system furniture according to an embodiment of the present disclosure connects the first connecting portion 362 of the first rod assembly 360 to the other side of the second rod 371 of the second rod assembly 370 in the system furniture provided with the first rod assembly 360 including the first rod 361 and the first connecting portion 362 and the second rod assembly 370 including the second rod 371 and the second connecting portion 372.

[0266] The coupling member 363 provided with the coupling groove 364 extending in the longitudinal direction is provided on one side of the first connecting portion 362 of the first rod assembly 360. The rod connection device 400 for use in the system furniture according to an embodiment of the present disclosure includes the first connecting member 410 provided with the coupling projection 411 extending in the longitudinal direction and inserted into the coupling groove 364, and the second connecting member 420 coupled to the other side of the second rod 371 of the second rod assembly 370 and to which the first connecting member 410 is rotatably coupled. When the coupling projection 411 is inserted into the coupling groove 364 and the first connecting member 410 is rotated, the coupling projection 411 may not be released from the coupling groove 364.

[0267] Since the rod connection device 400 for use in the system furniture according to the embodiment of the present disclosure is the same as the rod connection device 400 included in the system furniture provided with the rod connection device, according to the embodiment of the present disclosure, a detailed description thereof is omitted.

[0268] The system furniture provided with the rod connection device, according to the embodiment of the present disclosure, has the following effects. Since the configuration that is the same as or similar to the configuration of the best mode has the same or similar effects, a redundant description thereof is omitted.

[0269] The system furniture provided with the rod connection device, according to an embodiment of the present disclosure, has an advantage in that the height of the hanger may be adjusted while allowing electrical connection by selectively coupling the connecting portion of the rod assembly to the plurality of coupling holes provided in the rail of the pillar portion and bringing the second electrode provided in the pillar portion into contact with the third electrode provided in the connecting portion of the rod assembly.

[0270] In addition, the system furniture provided with the rod connection device, according to an embodiment of the present disclosure has an advantage in that the plurality of rod assemblies may be installed continuously at the same height by connecting the first connecting portion provided on one side of the first rod assembly to the other side of the second rod assembly through the rod connection device.

[0271] The system furniture provided with the rod connection device, according to an embodiment of the present disclosure, has an advantage in that, without using wires, the first electrode and the second electrode may be electrically connected to each other through the process of installing, coupling, and assembling the pillar portion to the connecting bracket and the second electrode and the third electrode may be connected to each other through the process of installing, coupling, and assembling the first connecting portion of the first rod assembly and the second connecting portion of the second rod assembly to the pillar portion.

[0272] The system furniture provided with the rod connection device, according to an embodiment of the present disclosure, has an advantage in that the heights of the first rod assembly and the second rod assembly may be adjusted while allowing electrical connection by selectively connecting the first connecting portion of the first rod assembly and the second connecting portion of the second rod assembly to the plurality of coupling holes provided in the rail of the pillar portion and bringing the second electrode provided in the pillar portion into contact with the third electrodes provided in the first connecting portion and the second connecting portion.

[0273] In addition, the system furniture provided with the rod connection device, according to an embodiment of the present disclosure, has an advantage that may be easy to install and dismantle the hanger and may easily find an electrical short circuit point by electrically separating the bottom plate, the pillar portion, and the hanger from each other and bringing the first electrode provided in the bottom plate, the second electrode provided in the pillar portion, and the third electrode provided in the connecting portion of the rod assembly into contact with each other so that electricity is supplied thereto.

[0274] A third embodiment according to another aspect of the present disclosure relates to system furniture provided with an electrode bracket device, which is capable of making it easy to install and dismantle a shelf while allowing the height of the shelf to be adjusted, and allowing electrical connection through the electrode bracket device without using wires. Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to FIGS. 1 to 4 and 18 to 23.

[0275] The system furniture provided with the electrode bracket device, according to an embodiment of the present disclosure, includes a bottom plate 110, a pillar portion 140, a shelf 160, and an electrode bracket device 600.

[0276] The above description of the best mode is applied to the description of FIGS. 1 to 5.

[0277] Referring to FIGS. 5 and 24, the connecting portion 161 may be coupled to the pillar portion 140 by fitting the hook portion 162 formed in a hook shape into the coupling hole 142. The hook portion 162 may be coupled to one or more of the plurality of coupling holes 142.

[0278] According to an embodiment of the present disclosure, the height at which the connecting portion 161 is coupled to the pillar portion 140 may be adjusted by changing the position at which the hook portion 162 is coupled to the plurality of coupling holes 142. In this manner, the height at which the shelf 160 is coupled to the pillar portion 140 may be adjusted.

[0279] The support portion 163 of the shelf 160 is provided between the two connecting portions 161. The support portion 163 may be formed in a plate shape and the support portion 163 may be a support plate of the shelf 160.

[0280] Referring to FIG. 25, the electrode bracket device 600 is provided in the connecting portion 161 and the electrode bracket device 600 may be a bracket for installing a connection electrode 630 in the connecting portion 161.

[0281] The electrode bracket device 600 includes a housing 610, a substrate 620, the connection electrode 630, and a pogo pin 640.

[0282] Referring to FIGS. 25 and 26, the housing 610 is provided with a hook housing 611 protruding outward from the connecting portion 161 so as to be fitted into the coupling hole 142 of the rail 141 and is coupled to the connecting portion 161.

[0283] The housing 610 may be coupled to the connecting portion 161. 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.

[0284] The hook housing 611 may be formed in a shape corresponding to the shape of the hook portion 162. The hook housing 611 may be fitted into the coupling hole 142 of the rail 141.

[0285] As described above, by fitting the hook portion 162 of the connecting portion 161 into the coupling hole 142, the connecting portion 161 may be coupled to the pillar portion 140.

[0286] The hook housing 611 may replace any one of the plurality of hook portions 162 provided in the connecting portion 161. According to an embodiment of the present disclosure, any one of the plurality of hook portions 162 provided so as to connect the connecting portion 161 to the pillar portion 140 may be replaced with the hook housing 611.

[0287] Referring to FIGS. 26 and 27, the hook housing 611 may be provided with the connection electrode 630. The hook housing 611 may be provided with a pair of the connection electrodes 630. The hook housing 611 may be provided with the connection electrode 630 formed as a positive electrode and the connection electrode 630 formed as a negative electrode.

[0288] The hook housing 611 according to an embodiment of the present disclosure is provided with both the pair of connection electrodes 630 formed as the negative electrode and the positive electrode. By providing both the pair of connection electrodes 630 formed as the negative electrode and the positive electrode in the hook housing 611, the connection electrode 630 and the second electrode 150 may be electrically connected to each other while minimizing the electrode exposure point.

[0289] Specifically, when the connecting portion 161 is coupled to the pillar portion 140, the hook housing 611 is fitted into the coupling hole 142 of the rail 141, and the second electrode 150 and the connection electrode 630 may come into contact with each other. The connection electrode 630 may be formed as the pair of electrodes including the negative electrode and the positive electrode, and the pair of connection electrodes 630 may be provided in one hook housing 611.

[0290] When the hook housing 611 is fitted into the coupling hole 142 of the rail 141, the negative electrode of the connection electrode 630 may come into contact with the negative electrode of the second electrode 150 and the positive electrode of the connection electrode 630 may come into contact with the positive electrode of the second electrode 150. In this manner, the second electrode 150 and the connection electrode 630 may be electrically connected to each other.

[0291] As described above, the second electrode 150 is made of a thin-film and extends along the height direction of the pillar portion 140. Accordingly, regardless of the height at which the shelf 160 is coupled to the pillar portion 140, the second electrode 150 and the connection electrode 630 may come into contact with each other so as to be electrically connected to each other.

[0292] According to an embodiment of the present disclosure, the connection electrode 630 may include a connection electrode connecting portion 631 that protrudes outward from the hook housing 611 while being bent. Referring to FIG. 28, the connection electrode connecting portion 631 may protrude outward from the hook portion 162 while being bent.

[0293] When the hook housing 611 is fitted into the coupling hole 142 of the rail 141, the connection electrode connecting portion 631 protruding from the hook housing 611 may come into contact with the second electrode 150, so that the connection electrode 630 and the second electrode 150 may be electrically connected to each other.

[0294] Here, the connection electrode connecting portion 631 may include a negative electrode and a positive electrode. When the connection electrode connecting portion 631 comes into contact with the second electrode 150 made of the thin-film, the negative electrode of the second electrode 150 may come into contact with the negative electrode of the connection electrode connecting portion 631 and the positive electrode of the second electrode 150 may come into contact with the positive electrode of the connection electrode connecting portion 631.

[0295] In this manner, the system furniture provided with the electrode bracket device, according to an embodiment of the present disclosure, may electrically connect the second electrode 150 to the connection electrode 630 simply by a process of coupling or assembling the hook portion 162 and the hook housing 611 of the shelf 160 to the pillar portion 140.

[0296] Since the second electrode 150 according to the embodiment of the present disclosure is made of a thin-film extending along the height direction of the pillar portion 140, the connection electrode 630 and the second electrode 150 may be electrically connected by coming into contact with each other, regardless of the height at which the hook housing 611 is coupled to the pillar portion 140.

[0297] That is, regardless of the position at which the hook portion 162 and the hook housing 611 are fitted into and coupled to the plurality of coupling holes 142, the second electrode 150 and the connection electrode 630 may be electrically connected by coming into contact with each other. In this manner, even when the height at which the shelf 160 is installed is adjusted with respect to the pillar portion 140, the second electrode 150 and the connection electrode 630 may be electrically connected to each other by coming into contact with each other.

[0298] According to an embodiment of the present disclosure, the connection electrode connecting portion 631 may be made of an elastic member and, before the hook housing 611 is fitted into the coupling hole 142, the connection electrode connecting portion 631 may be in a state of being spread outward.

[0299] When the hook housing 611 is fitted into the coupling hole 142, the connection electrode connecting portion 631 spread outward may be gathered inward by the pillar portion 140. That is, the connection electrode connecting portion 631 may be press-fitted to the inner side of the pillar portion 140 through the coupling hole 142 while the connection electrode connecting portion 631 spread to the outside of the hook housing 611 is gathered inward.

[0300] When the connection electrode connecting portion 631 is gathered inward by the pillar portion 140, an elastic restoring force is generated in the connection electrode connecting portion 631 made of an elastic member. When the hook housing 2110 is fitted into the coupling hole 142, the connection electrode connecting portion 631 may be elastically pressurized to be spread outward by the elastic restoring force.

[0301] In this manner, when the hook housing 611 is fitted into the coupling hole 142, the connection electrode connecting portion 631 may be brought into firm contact with the second electrode 150 by elastically pressurizing the connection electrode connecting portion 631 to be spread outward.

[0302] Referring to FIGS. 26 and 28, the substrate 620 is provided inside the housing 610. The connection electrode 630 may be connected to one side of the substrate 620. An electric circuit is provided inside the substrate 620. The pogo pin 640 may be provided on the other side of the substrate 620.

[0303] The pogo pin 640 protrudes outward from the housing 610 and is provided on the other side of the substrate 620. The pogo pin 640 may be provided in a pair and protrude outward from the housing 610.

[0304] According to an embodiment of the present disclosure, the connection electrode 630 and the pogo pin 640 may be electrically connected to each other through the substrate 620. Specifically, the connection electrode 630 and the pogo pin 640 may be electrically connected to each other through the electric circuit provided on the substrate 620.

[0305] The electrode bracket device 600 may be provided with the pair of connection electrodes 630 and the pogo pin 640. The connection electrode 630 formed as the positive electrode is connected to one pogo pin 640 through the substrate 620 and the connection electrode 630 formed as the negative electrode is connected to another pogo pin 640 through the substrate 620.

[0306] Referring to FIG. 29, the electrode bracket device 600 according to an embodiment of the present disclosure may allow electrical connection between the connection electrode 630 and the pogo pin 640 without using wires by connecting the connection electrode 630 to the pogo pin 640 through the substrate 620.

[0307] When the connection electrode 630 is connected to the pogo pin 640 by using a wire, there is a risk of a wire breakage occurring inside the connecting portion 161. When an electrical short circuit occurs due to a wire breakage inside the connecting portion 161, there is a problem that it is difficult to find an electrical short circuit point and that it is difficult to repair a wire breakage.

[0308] The electrode bracket device 600 according to an embodiment of the present disclosure may connect the connection electrode 630 to the pogo pin 640 through the substrate 620 without using wires, thereby preventing a wire breakage from occurring and easily finding an electrical short circuit point.

[0309] Referring to FIG. 30, the pogo pin 640 may come into contact with a contact terminal 564 provided on the side surface of the support portion 163 of the shelf 160. The contact terminal 564 is electrically connected to the pogo pin 640 by coming into contact with the pogo pin 640. As the pogo pin 640 and the contact terminal 564 are connected to each other, electricity supplied through the connection electrode 630 is transferred to the contact terminal 564.

[0310] The contact terminal 564 may be connected to various electric devices, such as the lamp 180 provided inside the shelf 160, and may supply electricity to various electric devices provided inside the shelf 160 through the contact terminal 564.

[0311] The system furniture provided with the electrode bracket device, according to an embodiment of the present disclosure, may include the lamp 180 provided on the shelf 160 and connected to the connection electrode 630. The lamp 180 is electrically connected to the connection electrode 630 and the lamp 180 may be provided at various points of the shelf 160.

[0312] The lamp 180 is electrically connected to the contact terminal 564. The lamp 180 may be electrically connected to the connection electrode 630 through the pogo pin 640. The lamp 180 may be formed in the form of a diffusion plate. However, the present disclosure is not limited thereto and the lamp 180 may be provided on the shelf 160 in various forms.

[0313] The first electrode 130 provided in the connecting bracket 120 is supplied with electricity through the electrical connection line 121 and the electricity supplied to the first electrode 130 is transmitted to the second electrode 150. The electricity transmitted to the second electrode 150 is transmitted to the connection electrode 630, and the electricity transmitted to the connection electrode 630 is transmitted to the contact terminal 564 through the substrate 620 and the pogo pin 640. The electricity transmitted to the contact terminal 564 is transmitted to the lamp 180, so that light is emitted from the lamp 180.

[0314] Referring to FIGS. 29 and 31, the electrode bracket device 600 according to an embodiment of the present disclosure includes a first support portion 650 and a second support portion 660 that are provided inside the hook housing 611 and support one connection electrode connecting portion 631.

[0315] As described above, the connection electrode connecting portion 631 protrudes outward from the hook housing 611. The connection electrode connecting portion 631 may be in a state of being spread outward before the hook housing 611 is fitted into the coupling hole 142.

[0316] As the connection electrode connecting portion 631 spread to the outside of the hook housing 611 is gathered inward and the connection electrode connecting portion 631 is press-fitted through the coupling hole 142, the connection electrode connecting portion 631 and the second electrode 150 may be brought into firm contact with each other.

[0317] According to an embodiment of the present disclosure, since the connection electrode connecting portion 631 is made of an elastic member, the connection electrode connecting portion 631 returns to the form protruding outward from the hook housing 611 when the hook housing 611 is separated from the coupling hole 142.

[0318] However, when the connection electrode connecting portion 631 is used repeatedly or when the connection electrode connecting portion 631 is press-fitted into the coupling hole 142 for a long period of time, there is a risk that elastic deformation may occur in the connection electrode connecting portion 631.

[0319] In case where elastic deformation occurs in the connection electrode connecting portion 631, even when the hook housing 611 is separated from the coupling hole 142, the connection electrode connecting portion 631 may not return to the form protruding outward from the hook housing 611. Accordingly, there is a risk that the connection electrode connecting portion 631 and the second electrode 150 may not be brought into firm contact with each other when the connecting portion 161 is reused.

[0320] The first support portion 650 and the second support portion 660 may be members to prevent this problem. Referring to FIG. 31, the first support portion 650 includes a first upward slope portion 651 that forms an upward slope from the substrate 620 in the direction of the hook housing 611 and a first downward slope portion 652 that forms a downward slope from the substrate 620 in the direction of the hook housing 611.

[0321] Referring to FIG. 29, one of the pair of connection electrode connecting portions 631 may include an upward slope and a downward slope, and a point where the upward slope and the downward slope meet may protrude outward from the hook housing 611.
