SUMMARY OF INVENTION

Technical Problem

However, in the above-described configurations, in a case where the top plate is long in one direction and a gap between the support legs is wide, or the like, if a load acting on the top plate is large, the top plate and the frame member may be bent downward, and the lower end portions of the support legs may be deformed in a direction in which a gap between the lower end portions is widened.

In order to prevent this phenomenon, it is considered that the top plate or the frame member is thickened in up and down directions to increase the strength thereof. However, in this method, the space below the top plate is narrowed, and thus, an interference with a user's lower limbs may occur.

An object of the present invention is to provide a tabletop-equipped article of furniture capable of suppressing an interference with a user' lower limbs while increasing strength thereof.

However, in the configuration disclosed in Patent Document 2, the horizontal member which connects the legs to each other is provided below the top plate, a user's lower limbs interfere with the horizontal member, and a lower limb accommodation space cannot be sufficiently secured.

In addition, in the configuration disclosed in Patent Document 1, if the top plate is long in one direction and the gap between the support legs is wide, the top plate and the frame member may be bent downward by the load acting on the top plate, and the lower end portions of the support legs may be deformed in the direction in which the gap between the lower end portions is widened. In order to prevent this phenomenon, it is considered that the top plate or the frame member is thickened in the up and down directions to increase the strength thereof. However, in this method, the space below the top plate is narrowed, and thus, a lower limb accommodation space cannot be sufficiently secured.

Moreover, as shown in Patent Documents 1 and 2, in order to insert the wire into the inside of the support legs, the wire is exposed along the floor surface from a power source or the like provided on the floor surface to the lower end portions of the support legs. Accordingly, the appearance is likely to be impaired or a user is likely to step on the wire along the floor surface below the top plate.

Therefore, another object of the present invention is to provide a tabletop-equipped article of furniture capable of suppressing an interference with a user's lower limb while increasing strength thereof, suppressing an exposure of the wire, and improving the appearance thereof.

Each groove 262 is continuously formed over the entire length of the long side of the beam material 260 along the long side of the beam material 260. Each groove 262 is formed in a so-called dovetail groove shape in which an opening width 2s2 on a groove bottom portion 262b side in the up and down directions is wider than an opening width 2s1 on the side surface 260a of the beam material 260 in the up and down directions.

In the beam material 260 configuring the first beams 243 and the second beams 244, the side surface 260a on which the groove 262 is formed is disposed toward the inside of the table 210. In a state where an upper surface 260t of the beam material 260 abuts a lower surface 230b of the top plate 230, the beam material 260 is fixed to the top plate 230 via attachment brackets 271.

In the way, the first beams 243 and the second beams 244 are fixed to the lower surface 230b of the top plate 230 via the plurality of attachment brackets 271, and thus, the upper connection member 240 is connected to the lower surface 230b of the top plate 230.

For example, the top plate 230 is configured of a panel-shaped core material 231 and skin materials 232 and 233 which cover upper and lower surfaces 231f and 231g of the panel-shaped core material 231. The core material 231 is formed of an aluminum alloy, cardboard such as fiberboard or corrugated fiberboard, or the like, and has a honeycomb structure in which a plurality of holes 231h which penetrate the core material 231 in the up and down directions and have hexagonal cross-sections are arranged in planes along the surfaces 231f and 231g. The skin materials 232 and 233 are formed of a resin based material, a wood based material, or the like, and are adhered to the upper and lower surfaces 231f and 231g of the core material 231.

In the connection bracket 272, an insertion hole 272h which penetrates the connection bracket 272 perpendicularly to the first flat surface portion 272a and an insertion hole 272j which penetrates the connection bracket 272 perpendicularly to the second flat surface portion 272b are formed. The connection bracket 272 can be used by changing the orientation of the attachment bracket 271.

In the connection bracket 272, a bolt 283 is inserted into the insertion hole 272h, a tip portion of the bolt 283 is screwed into the seat member 282 inserted into the upper groove 262 of the beam material 260 configuring the second beam 244, and thus, the connection bracket 272 and the second beam 244 (beam material 260) are connected to each other. Moreover, the seat member 282 is inserted into the upper groove 262 of the beam material 260 configuring the connection beam 249, a bolt 284 is screwed into the seat member 282 in the groove 262 through insertion hole 272j, and thus, the connection bracket 272 and the connection beam 249 (beam material 260) are connected to each other.

As shown in FIGS. 8 and 9, the lower connection member 250 is provided along the floor surface F and connects lower end portions (lower portions) 220b of the plurality of legs 220 to each other.

As shown in FIGS. 12, 13, and 14, each of the base portions 251a (refer to FIG. 12) and the extension portions 251b and 251b of the end plates 251 and the connection beams 252 (refer to FIG. 12) configuring the lower connection member 250 includes a plate-shaped plate portion (connection portion) 255 which is thin in the up and down directions and extension wall portions 256 which are integrally formed with a lower surface 255b of the plate portion 255 and extend downward from the lower surface 255b. The extension wall portions 256 are continuously formed on both sides in a width direction (a horizontal direction orthogonal to the direction in which the plate portion 255 is continued) of the plate portion 255 along the longitudinal direction of the plate portion 255. As shown in FIGS. 12 and 14, each of the extension wall portions 256 is formed to be offset with respect to an end portion 255s of the plate portion 255 in the width direction by a predetermined dimension toward the inside in the width direction. The extension wall portion 256 functions as a rib which increases the stiffness of the plate portion 255.

In this way, a downward C-shaped wire accommodation portion Cs, which is surrounded by the lower surface 255b of the plate portion 255 and the extension wall portions 256 and 256 on both sides in the width direction, is formed below the lower connection member 250.

As shown in FIGS. 13 and 14, the leg 220 is provided on each extension portion 251b of each end plate 251 of the lower connection member 250. The end plate 251 of the lower connection member 250 abuts on the lower end portion 220b of the leg 220 from below. In the extension portion 251b, a thickness 2T1 of the plate portion 255 in the up and down directions of a leg support portion 251c positioned below the lower end portion 220b of the leg 220 is set to be larger than a thickness 2T2 of the plate portion 255 in a portion except for the leg support portion 251c (a portion in which the leg 220 is not installed).

Moreover, as shown in FIGS. 12 and 14, wire insertion holes (opening portions) 257 and 257 which penetrate the plate portion 255 in the up and down directions are formed in the leg support portion 251c.

In addition, in the leg support portion 251c, bolt insertion holes 258 and 258 which penetrate the plate portion 255 in the up and down directions are formed on both sides of the extension portion 251b in the longitudinal direction with respect to the wire insertion holes 257 and 257. In addition, in the leg support portion 251c, a female screw hole 259 which penetrates the plate portion 255 in the up and down directions is formed between the wire insertion holes 257 and 257.

The wire insertion holes 257, the bolt insertion holes 258 and 258, and the female screw hole 259 are formed between the extension wall portions 256 and 256 on both sides of the plate portion 255 in the width direction.

As shown in FIG. 12, each of the leg 220 includes a hollow tubular body 221 which has a rectangular shape in a plan view and forms an outer shell of the leg 220 and partition walls 222 and fixing plate portions 223 provided inside the tubular body 221. Two partition walls 222 are provided inside the tubular body 221 with a gap therebetween along a longitudinal direction Q of the leg 220 in a plan view. The partition walls 222 are each provided with a gap therebetween in the longitudinal direction Q to face side wall portions 221a and 221a positioned on both end portions of the tubular body 221 in the longitudinal direction Q. Accordingly, a wire insertion space Sh which is continued in the up and down directions is formed between the partition walls 222 and 222 inside the tubular body 221 of the leg 220. A communication portion 229 which is open downward and communicates with the wire insertion space Sh is formed at the lower end portion 220b of the leg 220. In addition, the upper end portion 220t (refer to FIG. 8) of the leg 220 is open upward and communicates with the wire insertion space Sh.

Each of the fixing plate portions 223 is provided to connect the side wall portion 221a and the partition wall 222 to each other in each of the both end portions of the tubular body 221 in the longitudinal direction Q. The fixing plate portion 223 faces the leg support portion 251c of the end plate 251 of the lower connection member 250 with a gap therebetween above the leg support portion 251c and is provided above the lowest end 220s of the leg 220 by a predetermined dimension. In addition, in the fixing plate portion 223, a bolt insertion hole 223h which penetrates the fixing plate portion 223 in the up and down directions is formed.

In a state where the leg 220 is placed on the leg support portion 251c of the end plate 251 of the lower connection member 250, a bolt (connector) 290 is inserted into each of the bolt insertion holes 258 and 258 from the lower side of the plate portion 255, and a tip portion 290s of the bolt 290 protrudes upward through the bolt insertion hole 223h of the fixing plate portion 223. A nut 291 is screwed into the tip portion 290s of the bolt 290, and thus, the leg 220 is connected to the leg support portion 251c of the end plate 251 of the lower connection member 250. Here, a head portion 290b of the bolt 290 is set to be lower than a protrusion height of the bolt 290 toward the lower portions of the extension wall portions 256 and 256 such that the head portion 290b does not come into contact with the floor surface F in a state of abutting the lower surface 255b of the plate portion 255.

In the leg support portion 251c of the end plate 251 to which the lower end portion 220b of the leg 220 is joined as described above, the wire insertion holes 257 and 257 communicates with the wire insertion space Sh between the partition walls 222 and 222 of the leg 220.

In addition, in the leg support portion 251c of the end plate 251 of the lower connection member 250, a screw shaft portion 292n of an adjuster 292 is screwed into the female screw hole 259 between the wire insertion holes 257 and 257 from below the plate portion 255. The adjuster 292 rotates around an axis of the screw shaft portion 292n, the adjuster 292 protrudes or contracts downward, and thus, a disk-shaped ground portion 292a which is formed on a lower end of the adjuster 292 can come into contact with the floor surface F. Accordingly, it is possible to adjust a level of the table 210 by absorbing unevenness of the floor surface F.

In the table 210 configured as described above, wires 2200 along the floor surface F are accommodated in the wire accommodation portion Cs formed to be surrounded by the lower surface 255b of the plate portion 255 and the extension wall portions 256 and 256 on both sides in the width direction below the lower connection member 250, and thus, the wires 2200 can be introduced to the lower portion of the leg 220 along the connection beam 252 and the end plate 251 of the lower connection member 250. The wires 2200 pass through the wire insertion holes 257 formed in the leg support portion 251c of the end plate 251 below the leg 220 and is inserted into the wire insertion space Sh formed in the leg 220. The wires 2200 are introduced to the upper portion of the leg 220 through the wire insertion space Sh and are guided to the top plate 230 through an opening (not shown) formed in the upper end portion of the leg 220.

In the table 210 configured as described above, the plurality of legs 220 which uprightly stand on the floor surface F, the top plate 230 which is supported on the plurality of legs 220, and the lower connection member 250 which is provided along the floor surface F and connects the lower end portions 220b of the plurality of legs 220 to each other are provided, and the wire accommodation portion Cs continued along the direction in which the lower end portions 220b of the leg 220 are connected to each other is formed on the lower surface of the lower connection member 250.

In this way, the lower end portions 220b of the adjacent legs 220 in the plurality of legs 220 are connected to each other by the lower connection member 250, and thus, each leg 220 is rigidly fixed. Accordingly, it is possible to prevent the legs 220 from being thickened, and it is possible to increase strength of a structure configured of the plurality of legs 220 and the lower connection member 250.

Moreover, the lower connection member 250 is provided along the floor surface F, and thus, it is possible to prevent the lower connection member 250 from interfering with a user's lower limbs. In addition, the wires 2200 along the floor surface F can be accommodated in the wire accommodation portion Cs formed on the lower surface of the lower connection member 250, and thus, it is possible to suppress the exposure of the wires 2200 below the top plate 230, and it is possible to suppress the interference between a user's lower limbs and the wires. Accordingly, it is possible to secure the lower limbs accommodation space below the top plate 230.

Therefore, according to the table 210, it is possible to suppress the interference with a user' lower limbs while increasing the strength of each leg 220, to suppress the exposures of the wires 2200, and to improve the appearance and usability of the table 210.

Moreover, the lower connection member 250 includes the plate portion 255 which is continued in the direction in which the lower end portions 220b of the legs 220 are connected to each other and the extension wall portions 256 which protrude downward from the lower surface of the plate portion 255 and are formed with a gap therebetween on both sides of the plate portion 255 in the width direction, and the space surrounded by the plate portion 255 and the extension wall portions 256 becomes the wire accommodation portion Cs. According to this configuration, it is possible to easily form the downward C-shaped wire accommodation portion Cs by the plate portion 255 and the extension wall portions 256 on both sides.

In addition, the lower connection member 250 is formed in the downward C shape by the plate portion 255 and the extension wall portions 256 on both sides, and thus, the plate portion 255 is reinforced by the extension wall portions 256 on both sides to be strengthened.

It is possible to rigidly connect the lower end portions 220b of the plurality of legs 220 to each other by the lower connection member 250.

Moreover, the upper surface of the lower connection member 250 becomes the plate portion 255, and thus, it is possible to decrease the dimension of the lower connection member 250 protruding upward from the floor surface F.

In addition, the extension wall portions 256 and 256 are formed to be offset toward the inside in the width direction with respect to both end portion 255s and 255s of the plate portion 255 in the width direction. Accordingly, the plate portion 255 appears to float upward from the floor surface F, the plate portion 255 appears thin, and the appearance improves.

In addition, each of the extension wall portions 256 is a rib extending along the direction in which the plate portion 255 is continued, and thus, the extension wall portion 256 functions as a reinforcing element of the plate portion 255. Accordingly, it is possible to increase the strength of the lower connection member 250.

Moreover, the bolts 290 which connect the legs 220 and the lower connection member 250 to each other and the adjusters 292 which come into contact with the floor surface F and adjust the heights of the legs 220 are provided between the extension wall portion 256 provided on both sides of the plate portion 255 in the width direction. Accordingly, it is possible to prevent the bolts 290 such as bolts or the adjusters 292 from being exposed to the outside, and it is possible to improve the appearance.

In addition, the wire insertion space Sh continued in the up and down directions is formed in each leg 220, and the communication portion 229 which communicates with the wire accommodation portion Cs and the wire insertion space Sh is formed on the lower surface of the leg 220. According to this configuration, the wires 2200 which are accommodated in the wire accommodation portion Cs below the lower connection member 250 and are disposed along the floor surface F are introduced into the wire insertion space Sh inside the leg 220 through the communication portion 229. Therefore, it is possible to further suppress the exposures of the wires 2200.

In addition, the lower connection member 250 is provided to abut the lower end portion 220b of each leg 220 from below, and the wire insertion holes 257 which communicate with the wire accommodation portion Cs below the lower connection member 250 and the wire insertion space Sh of the leg 220 are formed at the portion of lower connection member 250 abutting the lower end portion 220b of each leg 220. According to this configuration, the wires 2200 which are accommodated in the wire accommodation portion Cs below the lower connection member 250 and are disposed along the floor surface F are introduced into the wire insertion space Sh inside the leg 220 through the wire insertion holes 257 formed in the lower connection member 250. Therefore, it is possible to suppress the exposure of the wires 2200.

Moreover, in the plurality of legs 220 of the table 210, the adjacent legs 220 are connected to each other by the lower connection member 250 and the upper connection member 240, and thus, each leg 220 is rigidly fixed by the upper end portion 220t and the lower end portion 220b. Accordingly, it is possible to prevent the legs 220 from being thickened, and thus, it is possible to increase the strength of a support structure of the top plate 230 configured of the plurality of the legs 220, the lower connection member 250, and the upper connection member 240.

In addition, the portions 2100A and 2100B recessed toward the inside of the top plate 230 are formed between the adjacent legs 220 by the lower connection member 250 and the upper connection member 240, and thus, a user's lower limbs can be accommodated in the recessed portions 2100A and 2100B.

As a result, it is possible to increase strength of the legs 220, to suppress an interference with a user's lower limb below the top plate 230, and to secure a wide lower limbs accommodation space.

In addition, in the lower connection member 250 and the upper connection member 240, the adjacent legs 220 in the first direction X are connected to each other by the end connection portions 241 and the end plates 251. Moreover, in the lower connection member 250 and the upper connection member 240, the end connection portions 241 facing each other in the second direction Y are connected to each other by the second beams 244 and the end plates 251 facing each other in the second direction Y are connected to each other by the connection beam 252. According to this configuration, wide gaps are provided between one side and the other side of the top plate 230 along the second direction Y, and thus, even when the plurality of legs 220 are provided, the upper end portions 220t and the lower end portions 220b of the plurality of legs 220 can be rigidly and integrally connected to each other.
