SUMMARY OF INVENTION
Technical Problem
[0012] 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.
[0013] 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.
[0014] 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.
[0015] However, in the configuration disclosed in Patent Document

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.
[0016] 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.
[0017] 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.
[0018] 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

top plate 130 configured of all the legs 120, the lower connection
member 150, and the upper connection member 140.
[0080] In addition, the portions 1100A and 1100B recessed toward
the inside of the top plate 130 are formed between the adjacent
legs 120 by the lower connection member 150 and the upper
connection member 140, and thus, a user's lower limbs can be
accommodated in the recessed portions 1100A and 1100B.
[0081] As a result, it is possible to increase the strength of the
legs 120, to suppress an interference with a user's lower limbs
below the top plate 130, and to secure a wide lower limbs
accommodation space.
[0082] In addition, in the lower connection member 150 and the
upper connection member 140, the adjacent legs 120 in the first
direction X are connected to each other by the end connection
portions 141 and the end plates 151. Moreover, in the lower
connection member 150 and the upper connection member 140, the end
connection portions 141 facing each other in the second direction Y
are connected to each other by the second beams 144 and the end
plates 151 facing each other in the second direction Y are
connected to each other by the connection beam 152. According to
this configuration, wide gaps are provided between one side and the
other side of the top plate 130 along the second direction Y, and
thus, even when the plurality of legs 120 are provided, the upper
end portions 120t and the lower end portions 120b of all the legs
120 can be rigidly and integrally connected to each other.
[0083] In addition, the lower connection member 150 is formed in a
plate shape positioned to be parallel to the floor surface F.
According to this configuration, it is possible to decrease the
dimension of the lower connection member 150 protruding upward from
the floor surface F. Accordingly, it is possible to suppress the
interference between the lower connection member 150 and a user's
lower limbs while rigidly connecting together the lower end
portions 120b of the plurality of legs 120.
[0084] Moreover, the upper connection member 140 is fixed along the
lower surface of the top plate 130. Accordingly, the upper
connection member 140 can reinforce the top plate 130, and thus, it
is possible to increase the strength of the top plate 130.
Other Embodiments
[0085] In addition, the tabletop-equipped article of furniture of
the present invention is not limited to the embodiment described
with reference to the drawings, and various modified examples are
considered within a technical scope thereof.
FIRST MODIFIED EXAMPLE
[0086] FIG. 3 is a perspective view showing a first modification
example of the table 110.
[0087] In the above-described embodiment, the upper connection
member 140 and the lower connection member 150 have different
shapes from each other in a plan view. However, the present
invention is not limited to this.
[0088] For example, as shown in FIG. 3, an upper connection member
140A may be formed to have a shape similar to that of a lower
connection member 150 in a plan view, may extend in a V shape, and
may include end beams (first leg connection portions) 145 and 145
which connect the upper end portions 120t of the adjacent legs 120
in the first direction X to each other and a connection beam
(second leg connection portion) 146 which extends in the second
direction Y along the center portion in the first direction X of
the top plate 130 connects the end beams 145 and 145 to each
other.
SECOND MODIFICATION EXAMPLE
[0089] FIG. 4 is a perspective view showing a second modified
example of the table.
[0090] As shown in FIG. 4, hanging walls 145w, 145w, and 146w which
perpendicularly hang downward from the lower surface of the top
plate 130 and are positioned in a plane orthogonal to the lower
surface of the top plate 130 may be integrally formed with the end
beams 145 and 145 and the connection beam 146 configuring the upper
connection member 140B.
[0091] According to this configuration, the hanging walls 145w,
145w, and 146w partition a portion below the top plate 130 to
user's lower limbs spaces facing each other in a state where the
top plate 130 is interposed therebetween and can function as a
curtain plate which hides at least a portion of the lower limbs of
users facing each other in a state where the top plate 130 is
interposed therebetween. In addition, the upper connection member
140B can increase strength with respect to a force in the up and
down directions and can increase reinforcement effects of the top
plate 130.
[0092] Accordingly, as shown in FIG. 4, the upper connection member
140B may be formed in a curtain plate shape which is positioned in
a plane orthogonal to the lower surface of the top plate 130.

and the second direction Y. However, the present invention is not
limited to this and the longitudinal direction of each leg 120 may
be disposed to extend along the first direction X or the second
direction Y.
[0098] In addition, the shape of each leg 120 is not limited to the
approximately rectangular shape in a plan view and may be a
circular shape in a plan view, a polygonal shape in a plan view, or
the like.
[0099] In addition, the upper end portions 120t and the lower end

[0105] In the table 210 of this embodiment, for example, the top
plate 230 has an elliptical shape in a plan view. The top plate 230
is formed to be short in the first direction X along an upper
surface 230f of the top plate 230 and to be long in the second
direction Y orthogonal to the first direction X in a plane along
the upper surface 230f The shape of the top plate 230 is not
limited to the elliptical shape in a plan view and may be an oval
shape in a plan view, a rectangular shape in a plan view, or the
like.
[0106] As shown in FIG. 8, two legs 220 are provided in each of one
side and the other side of the top plate 230 in the second
direction Y. Each leg 220 has an approximately rectangular shape in
a plan view. A longitudinal direction of each leg 220 having an
approximately rectangular shape in a plan view is disposed to be
inclined in the first direction X and the second direction Y and to
extend outward in the second direction Y as being away from a
center portion in the first direction X of the top plate 230.
[0107] The upper connection member 240 connects upper end portions
220t of the plurality of legs 220 to each other. The upper
connection member 240 includes upper beams 242, first beams 243,

[0110] An end connection portion 241 is formed by the upper beams
242 and the first beam 243, and the end connection portion 241
connects together the upper end portions 220t of the legs 220
adjacent to each other in the first direction X along the upper
surface of the top plate 230.
[0111] A pair of second beams 244 is provided with a gap
therebetween in the first direction X. Each of the second beams 244
extends along the second direction Y and connects together the
upper beams 242 and 242 adjacent to each other in the second

[0112] FIG. 9 is a sectional view when the table is viewed in the
first direction. FIG. 10 is a sectional view showing a connection
structure between the upper connection member 240 and the top plate
230.
[0113] In addition, as shown in FIGS. 8 and 9, a plurality of
connection beams 249 are provided between the second beams 244 and
244 with gaps therebetween along the second direction Y. Each
connection beam 249 extends in the first direction X and both end
portions of the connection beam 249 are connected to the second
beams 244 and 244 via connection brackets 272 described later.
Accordingly, two second beams 244 and 244 and the plurality of
connection beams 249 are connected to each other in a ladder shape
in a plan view.
[0114] The first beams 243, the second beams 244, and the
connection beams 249 are formed by beam materials 260 as described
below.
[0115] As shown in FIG. 10, a cross section orthogonal to a long
side of each beam material 260 has an approximately rectangular
shape which is long in up and down directions, and two grooves 262
are formed on one side surface 260a of the beam material 260 with a
gap therebetween up and down.
[0116] 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.
[0117] 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.
[0118] Each attachment bracket 271 includes a first flat surface
portion 271a which abuts the lower surface 230b of the top plate
230 and a second flat surface portion 271b which is orthogonal to
the first flat surface portion 271a and abuts the side surface 260a
of the beam material 260. In the attachment bracket 271 used in the
second beam 244, a surface in the second direction Y is formed in
an approximately right triangle shape. In the attachment bracket
271, an insertion hole 271h which penetrates the attachment bracket
271 perpendicularly to the first flat surface portion 271a and an
insertion hole 271j which penetrates the attachment bracket 271
perpendicularly to the second flat surface portion 271b are
formed.
[0119] In the attachment bracket 271, a bolt 280 is screwed into a
screw hole 230h formed on the lower surface 230b of the top plate
230 in advance through the insertion hole 271h, and thus, the
attachment bracket 271 and the top plate 230 are connected to each
other. In addition, a seat member 282 in which a female screw hole
282n is formed is inserted into the upper groove 262 of the beam
material 260 configuring the first beams 243 and the second beams
244, a bolt 281 is screwed into the seat member 282 in the groove
262 through the insertion hole 271j, and thus, the attachment
bracket 271 and the first beam 243 and the second beams 244
configured of the beam material 260 are connected to each
other.
[0120] 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.
[0121] 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.
[0122] FIG. 11 is a planar sectional view showing a connection
structure between the upper connection member 240 and the
connection beam 249.
[0123] As shown in FIGS. 8 and 11, both end portions of the
connection beams 249 are connected to the beam materials 260 and
260 configuring the second beams 244 and 244 via the connection
brackets 272.
[0124] As shown in FIG. 11, each of the connection brackets 272
includes a first flat surface portion 272a which abuts the side
surface 260a of the beam material 260 of the second beam 244 and a
second flat surface portion 272b which is orthogonal to the first
flat surface portion 272a and abuts the side surface 260a of the
beam material 260 of the connection beam 249, and the connection
bracket 272 is formed in an approximately right triangular shape in
a plan view. 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.
[0125] 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.
[0126] 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.
[0127] FIG. 12 is a view when the lower connection member 250 is
viewed from below.
[0128] As shown in FIGS. 8 and 12, the lower connection member 250
includes end plates 251 and 251 which are provided on the one side
and the other side of the top plate 230 in the second direction Y
and a connection beam 252 which connects the end plates 251 and 251
to each other.
[0129] Each end plate 251 includes a base portion 251a which is
positioned at the center portion of the top plate 230 in the first
direction X, and extension portions 251b and 251b formed to extend
toward both sides in the first direction X from the base portion
251a toward the outside of the top plate 230 along the second
direction Y. The base portion 251a and the extension portions 251b
and 251b form a V shape.
[0130] The connection beam 252 is formed to extend along the second
direction Y at the center portion of the top plate 230 in the first
direction X. As shown in FIG. 12, both end portions 252a and 252a
of the connection beam 252 are each connected to the base portion
251a of one side end plate 251 and the base portion 251a of the
other side end plate 251 in the second direction Y via bolts and
nuts 253.
[0131] As shown in FIG. 8, in the upper connection member 240 and
the lower connection member 250, the second beams 244 and 244 and
the connection beam 252 are disposed inside an outer peripheral end
portion 230s of the top plate 230 in the first direction X. In
addition, in the upper connection member 240 and the lower
connection member 250, the first beams 243 and 243 and the
extension portions 251b and 251b of the end plate 251 are disposed
inside the outer peripheral end portion 230s of the top plate 230
in the first direction X in a plan view. Accordingly, when the
upper connection member 240 is viewed in plan, portions (recesses)
2100A which are recessed toward the inside of the top plate 230 are
formed between the adjacent legs 220. In addition, when the lower
connection member 250 is viewed in plan, portions (recesses) 2100B
which are recessed toward the inside of the top plate 230 are
formed between the adjacent legs 220.
[0132] FIG. 13 is a sectional view showing a connection structure
between the lower connection member 250 and the lower end portion
220b of each leg 220. FIG. 14 is a sectional view taken along line
D-D in FIG. 13.
[0133] 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.
[0134] 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.
[0135] 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).
[0136] 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.
[0137] 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.
[0138] 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.
[0139] 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.
[0140] 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.
[0141] 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.
[0142] 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.
[0143] 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.
[0144] 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.
[0145] 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.
[0146] 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.
[0147] 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.
[0148] 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.
[0149] 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.
[0150] 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.
[0151] 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.
[0152] 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.
[0153] 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.
[0154] 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.
[0155] 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.
[0156] 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.
[0157] 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.
[0158] 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.
[0159] 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.
[0160] 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.
[0161] 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.
Other Embodiments
[0162] In addition, the tabletop-equipped article of furniture of
the present invention is not limited to the embodiments described

examples are considered within the technical scope of the present
invention.
[0163] For example, in the above-described embodiments, the upper
connection member 240 is provided. However, the upper connection
member 240 is not an essential configuration. Moreover, in a case
where the upper connection member 240 is provided, the
configuration thereof is not particularly limited.
[0164] Moreover, the shape of the lower connection member 250 in a
plan view may be appropriately changed according to the number or
disposition of the legs, or the like.
[0165] Moreover, the shape of the wire accommodation portion Cs
formed in the lower connection member 250 is not limited to the
downward C shape and may be a semicircular shape or a
semi-elliptical shape which is open downward, or the like.
[0166] In addition, the lower connection member 250 integrally
connects four legs 220 to each other. However, the number, the
direction, or the like of the connected legs 220 can be
appropriately selected. For example, the lower connection member
250 may connect the adjacent legs 220 in the first direction X to
each other or may connect the adjacent legs 220 in the second
direction Y to each other. In addition, the lower connection member
may connect the legs 220, which face each other in an inclination
direction intersecting the first direction X and the second
direction Y, to each other.
[0167] In addition, the lower connection member 250 is provided to

However, the lower connection member 250 may abut on the side
surface of the lower end portion 220b of each leg 220 as long as
connection strength between the lower connection member 250 and the
lower end portion 220b of each leg 220 can be secured. In this
case, the wires 2200 accommodated in the wire accommodation portion
Cs of the lower connection member 250 are introduced into the wire
insertion space Sh of each leg 220, and thus, the communication
portion which communicates with the wire accommodation portion Cs
and the wire insertion space Sh may be formed on the side surface
of the lower end portion 220b of each leg 220.
[0168] In addition, in the lower connection member 250, the
extension wall portion 256 is formed in a rib shape which is
continued along the longitudinal direction of the plate portion
255. However, the present invention is not limited to this. The
extension wall portion 256 may be discontinuously formed along the
longitudinal direction of the plate portion 255. In this case, the
space between the extension wall portions 256 and 256 is
intermittently formed along the longitudinal direction of the plate
portion 255, and the wire accommodation portion continued along the
longitudinal direction is formed so as to connect the spaces
between the extension wall portions 256 and 256. In addition, the
wires 2200 along the floor surface F can be introduced into the
wire accommodation portion Cs through a gap between the adjacent
extension wall portions 256 and 256 in the longitudinal direction
of the plate portion 255.
[0169] In addition, the lower connection member 250 is formed in
the downward C shape configured of the plate portion 255 and the
extension wall portions 256. However, the shape of the lower
connection member 250 is not limited to this. For example, the
lower connection member 250 may be formed in a rectangular tubular
shape continued along the floor surface F, and the inside of the
lower connection member 250 may be a completely sealed wire
accommodation portion Cs.
[0170] Moreover, materials of the members such as the legs 220, the
top plate 230, the upper connection member 240, the lower
connection member 250, or the like configuring the table 210 shown
in the above-described embodiment are not particularly limited.
That is, the materials may be wood based materials, metallic based
materials, resin based materials, or a combination thereof.
[0171] In addition, the present invention is not limited to the
table 210 and can be similarly applied to other tabletop-equipped
articles of furniture.
[0172] Moreover, the configurations described in the above
embodiment can be selected or can be appropriately changed to other
configurations as long as it does not deviate from the gist of the
present invention.
