  An object of the present invention made in view of the above is to make it possible to suitably conceal cords dropped onto the floor without impairing workability during wiring.

  In the present invention, a predetermined furniture member that embodies the function of furniture, and a column that supports the furniture member and includes a wiring passage that extends vertically from the floor to the furniture member. And an upper wall that is coupled to the lower end portion of the support column, surrounds the outer periphery of the support column over substantially the entire periphery, and shields the floor around the support column, and at least a part of the upper wall is removable. A furniture comprising a base that is a member and is exposed to the floor when the cover member is removed is communicated with the wiring passage. According to this, after the cover member is detached and the cords are arranged in the space above the floor, the cover members can be remounted to shield the cords. That is, the cords dropped onto the floor via the wiring path of the support can be preferably concealed under the upper wall of the base.

  The base includes a plurality of leg blades that extend in the radial direction from the lower end of the support and are grounded, and a substantially partial gap in plan view between the leg blades is used as the space above the floor. For example, the structure for supporting the column is stabilized, and the gap between the leg blades can be effectively used as a wiring space.

  If the inner end portion of the cover member is in contact with or very close to the lower end portion of the support column, in other words, if the floor space that can be wired extends to the outer periphery of the support column, the support column extends from the floor space to the support column. The other part (the upper wall of the base or the like) is not obstructed between the entrance and exit of the wiring path, and the wiring work for introducing the cords on the floor into the wiring path is facilitated.

  An upper end surface of the inner end portion of the cover member is in contact with or very close to a lower end surface of the outer wall of the support column, and retaining means for holding the cover member inserted from the outside directly under the outer wall of the support column. If it is provided between the base and the cover member, it is difficult to see the gap between the cover member and the outer wall of the support column, and the quality of the furniture can be enhanced.

  If the wiring passage is open to the outer wall of the support column facing the floor space, the intermediate portion of the cords to be wired can be inserted from the outside into the wiring passage of the support column, making wiring work easier. It becomes.

  If a cap is detachably attached to the opening of the wiring passage, it is possible to improve the appearance by shielding the wiring passage at times other than during wiring work. Moreover, it is possible to prevent the cords wired in the wiring path from spilling.

  The present invention can be applied to furniture with a top board, a rack, and the like. In that case, the top plate or shelf on which the article can be placed corresponds to the furniture member.

An adjuster 213 is attached to the lower surface of the bottom wall 211 at the outer end of the leg blade 21, and the leg blade 21 is grounded to the floor via the adjuster 213.

  In addition, a receiving tool 214 into which a fastening tool 243 on the cover member 24 side described later is inserted is provided. The support 214 is a resin molded product that covers the base of the leg blade 21 from above, and engages a notch 216 formed at a corner where the bottom wall 211 and the side wall 212 intersect with a claw 217 at the lower end thereof. To attach to the substrate. The receiving tool 214 has an insertion port 218 that opens in a direction intersecting the extending direction of the leg blades 21, in other words, the normal direction of the side wall 212. The insertion port 218 exists in a pair on both sides of the leg blade 21. The opening directions of the two insertion ports 218 (in the separate receivers 214) located in the gap between the two adjacent leg blades 21 are substantially parallel. In the illustrated example in which a gap of about 60 ° is formed between the six leg blades 21, the extending direction of the leg blades 21 and the opening direction of the insertion port 218 of the receiving member 214 attached to the leg blades 21. Is at an angle of about 30 °.

  The side wall 212 of the leg blade 21 gradually increases in height from the outer end toward the inner end, and has an upper edge that rises rapidly in the vicinity of the inner end, and the lower edge is the lower plate. Recessed by being recessed upward by about 22 thicknesses. An upper wall 215 is attached to the upper edge of the side wall 212 by welding, screwing or the like, and the base of the leg blade 21 is closed from above.

At this time, the lower plate 22 is accommodated in a recess in the lower edge near the inner end of the side wall 212 of the leg blade 21 facing in the radial direction, and the upper plate 23 is placed near the inner end of the side wall 212 of the leg blade 21.

  The lower plate 22 is a disk member having an outer diameter substantially equal to the outer periphery of the support column 1, and has a plurality of (six in the illustrated example) screw insertion holes 221 intermittently along the circumferential direction. The screw insertion hole 221 is for passing the shaft portion of the male screw member 25. Each screw insertion hole 221 is located inward from the inner end of the bottom wall 211 so as not to overlap the bottom wall 211 of the leg blade 21 in plan view.

  The upper plate 23 is a disk material having an outer diameter smaller than the outer periphery of the support column 1 by the thickness of the cover member 24 (upper wall 241), and is intermittently provided in the circumferential direction (six in the illustrated example). The screw insertion opening 231 is cut out. Similarly to the screw insertion hole 221 of the lower plate 22, the screw insertion opening 231 is for passing the shaft portion of the male screw member 25, and each overlaps with each screw insertion hole 221 in plan view.

  In order to fix the leg blade 21 to the column 1, the upper plate 23 is brought into contact with the lower end surface of the column 1, and the male screw member 25 is inserted from below into the screw insertion hole 221 and the screw insertion opening 231. What is necessary is just to be screwed together in the internal thread formed in the lower end part of 16.

  In the present embodiment, when the leg blades 21 are fixed to the support column 1, the floor space, which is a gap between the two specific leg blades 21, communicates directly with the wiring passage 14. For this purpose, the side wall 212 (on the side facing the gap) of the two leg blades 21 is refracted at the inner end portion to ensure the width of the gap, and the upper plate 23 is provided with the two leg blades 21. A wiring opening 232 is cut out along the side wall 212. The outer edge of the wiring opening 232 overlaps the opening 15 of the outer wall 13 of the pillar 1 in plan view, and the opening width is substantially equal to the opening width of the outer wall 13 of the pillar 1. As a result, the space above the floor between the two leg blades 21 continues to the wiring passage 14 via the wiring opening 232. The floor space, the wiring opening 232 and the wiring passage 14 are consistently opened to the side of the furniture.

  The cover member 24 as a whole surrounds the outer periphery of the support column 1 over substantially the entire periphery, shields the floor around the support column 1, and is detachable from the leg blade 21.

Similar to the tray 34, the shelf 7 is below the top plate 4, and forms a wiring device arrangement space with the top plate 4. As shown in FIG. 12, the shelf 7 includes a shelf plate 71 and a support bracket 72 that supports each shelf plate 71.

  The shelf board 71 has a donut plate shape as a whole and is detachable from the arm 31. The shelf plate 71 is also divided into the same number (four in the illustrated example) as the number of gaps between the arms 31. Each shelf plate 71 is a thin plate having a substantially sector shape in plan view, and a reinforcing frame 711 having a substantially partial arc shape in plan view is integrally formed on the inner peripheral edge and the outer peripheral edge thereof.

  The support bracket 72 is a member that can be hooked on the top plate support portion 313 of the arm 31. The support bracket 72 has a substantially horizontal support surface and supports both sides of the shelf 71 in the circumferential direction from below, a standing wall 722 standing from the inner end of the support 721, and a support 721. And a side wall 723 joined to the side edge of the upright wall 722, and a latching portion 724 extending further inward from the upright wall 722. The latching portion 724 is biased toward the support body 721 with respect to the side wall 723 in plan view. An attachment claw 725 is formed on the latching portion 724. The mounting claw 725 protrudes substantially horizontally toward the side wall 723 side. The distal end portion of the mounting claw 725 extends in the radial direction so that the width dimension is larger than the proximal end portion.

  To attach the support bracket 72 to the arm 31, the attachment claw 725 is inserted into the upper portion of the attachment hole 316 formed in the top plate support portion 313, and the inner end of the side wall 723 is brought into contact with the side surface of the top plate support portion 313. After the contact, the support bracket 72 is dropped downward, and the attachment claw 725 may be engaged with the lower part of the attachment hole 316.

  The support brackets 72 are respectively attached to the top plate support portions 313 of the two adjacent arms 31, and the both sides in the circumferential direction of the shelf plate 71 are placed on the support bodies 721 of the support brackets 72, whereby the shelf plate 71 is placed in the tray 34. It can be mounted on the outer peripheral side of the. In a state in which each shelf plate 71 is mounted, the side end surface of one shelf plate 71 is in contact with or in close proximity to the side end surface of another adjacent shelf plate 71.

  When installing the shelf 7, the auxiliary bracket 73 may be used together with the support bracket 72. The auxiliary bracket 73 includes a support body 731 having a substantially horizontal support surface and supporting a circumferential intermediate portion of the shelf board 71 from below, and a side wall 732 joined to a side edge of the support body 731. The upper end of the refracted substantially horizontally. The auxiliary bracket 73 is attached to the lower surface of the top plate 4 by screwing or welding or the like with the side wall 732 passing through the slot hole 712 formed in the shelf plate 71.

  In this embodiment, the shelf 71 and the brackets 72 and 73 that support the shelf 71 are separated from each other, but the side wall 723 of the support bracket 72 and / or the side wall 732 of the auxiliary bracket 73 is provided integrally with the shelf 71. Not disturb.

  The procedure for wiring the cords to the furniture with the top plate of the present embodiment will be described. First, the cap 17 is removed from the opening 15 of the leg column 1 to open the wiring passage 14 in the leg column 1 to the outside. Next, the cover member 24 of the base 2 located below the wiring path 14 and the tray 34 positioned above the wiring path 14 are removed, and the floor 34, which is covered by the cover member 24, is shielded. Expose the wiring arrangement space. Then, an intermediate portion of the cords rising from the floor space is inserted and arranged in the wiring passage 14 from the side. Thereafter, the cap 17, the cover member 24, and the tray 34 are reattached to conceal the wiring passage 14, the floor space, and the wiring device arrangement space. The cords are pulled out on the top plate 4 through the opening 41 of the top plate 4 or connected to a wiring tool or the like placed on the tray 34 as necessary.

  According to the present embodiment, the predetermined furniture member 4 that functions as furniture, and the wiring passage 14 that supports the furniture member 4 and extends vertically from the floor toward the furniture member 4. And the upper wall 241 that is coupled to the lower end portion of the support column 1 and surrounds the outer periphery of the support column 1 over almost the entire periphery to shield the floor around the support column 1. At least a part of the upper wall 241 is a detachable cover member 24, and the floor space exposed when the cover member 24 is removed constitutes the furniture including the base 2 communicating with the wiring passage 14. Therefore, after the cover member 24 is detached and the cords are disposed in the space above the floor, the cover member 24 can be remounted to shield the cords. That is, the cords dropped onto the floor via the wiring passage 14 of the support column 1 can be preferably hidden under the upper wall 241 of the base 2.

  The base 2 includes a plurality of leg blades 21 that extend in the radial direction from the lower end of the support column 1 and come into contact with the ground, and a substantially partial gap in plan view between the leg blades 21 is used as the floor space. Therefore, the structure for supporting the support column 1 is stabilized, and the gap between the leg blades 21 can be effectively used as a wiring space.

  Since the inner end portion of the cover member 24 is in contact with or very close to the lower end portion of the support column 1, in other words, the floor space that can be wired extends to the outer periphery of the support column 1. From the door to the entrance / exit of the wiring passage 14 of the support column 1 is not obstructed by other members (such as the upper wall 241 of the base 2), and wiring work for introducing the cords on the floor into the wiring passage 14 is facilitated. .

  The upper end surface of the inner end portion of the cover member 24 is in contact with or very close to the lower end surface of the outer wall 13 of the support column 1, and the cover member 24 is inserted from the outside directly under the outer wall 13 of the support column 1. Since the holding means for holding is provided between the base 2 and the cover member 24, it is difficult to see the gap between the cover member 24 and the outer wall 13 of the support column 1, and the quality of the furniture can be improved.

  Since the wiring passage 14 opens in the outer wall 13 of the support column 1 facing the floor space, an intermediate portion of the cords to be wired can be inserted into the wiring passage 14 of the support column 1 from the outside. Work becomes easier.

  Since the cap 17 is detachably attached to the opening 15 of the wiring passage 14, the wiring passage 14 can be shielded at times other than during wiring work to improve the appearance. Further, it is possible to prevent the cords wired in the wiring passage 14 from spilling.

  Note that the present invention is not limited to the embodiment described in detail above. In particular, the application target of the present invention is not limited to furniture with a top plate, and can be applied to a rack or the like. In that case, a shelf board of the rack corresponds to the furniture member.

  Further, the top plate may have a square shape in plan view.

  Other specific configurations of each part can be variously modified without departing from the spirit of the present invention.

  The present invention can be applied to, for example, a single column table.
