Technical Field
[0001] The present invention relates to a furniture system which includes multiple furniture
items such as sofas.
Background Art
[0003] Multiple furniture items such as sofas may be arranged and installed on a floor (for
example, refer to Patent Document 1). In addition, in a case where a table or a cabinet
is installed so as to be adjacent to sofas or the like, furniture items of multiple
kinds may be arranged and installed.
[0004] For example, in a case of a sofa, the surface of the sofa is covered with a soft
cushion. If a user sits on the sofa, the cushion is deformed such that it bulges outside
when the cushion is pressed from the upper portion thereof. Accordingly, in a case
where other sofas or furniture items are installed to be adjacent to the sofa without
a gap therebetween, the adjacent other sofas or furniture items are pressed in a longitudinal
direction by the outwardly bulged cushion, and the positions thereof may deviate.
[0005] Therefore, a method is used, in which a plate is provided on the lower surface of
a sitting portion of a sofa, and the sofa and other sofas or furniture items are connected
to each other by bolt-tightening a connection metal fitting to the plate.
[0006] In addition, Patent Document 1 discloses a configuration in which a belt-shaped connection
member is provided on one sofa, and a connected member to which the connection member
is locked is provided on another sofa.

Summary of Invention
Technical Problem
[0008] However, bolt-tightening the connection metal fitting takes much labor.
[0009] In addition, in a furniture item such as a sofa, there may not be a sufficient gap
below the lower surface of the sitting portion, and it may be difficult to bolt-tighten
the connection metal fitting to the lower surface of the sitting portion. If a furniture
item such as a sofa is dropped down sideways or is vertically inverted, a bolt-fastening
operation is easily performed. However, in a case where the furniture item is heavy
or the furniture item may be damaged if the furniture item is vertically inverted,
it may be difficult to make the furniture item drop down sideways or to vertically
invert the furniture item.
[0010] In addition, in the case where the connection member is locked to the connected member
like in Patent Document 1, when the positions of the sofas have deviated, the locking
between the connection member and the connected member may be released.
[0011] Accordingly, an object of the present invention is to provide a furniture system
in which furniture items may be connected easily and reliably and positional deviation
of the furniture items is prevented.
Solution to Problem
[0012] The present invention adopts the following means in order to solve the above-described
problems.
[0013] According to an aspect of the present invention, a furniture system includes: multiple
furniture items which are disposed to be adjacent to each other; and a connection
member which connects the multiple furniture items to each other, in which at least
one of two furniture items adjacent to each other includes an elastically deformable
cushion portion on an outer surface thereof facing the other of the two furniture
items adjacent to each other, the connection member includes connection portions which
are connected to each of the furniture items on both end portions of the connection
member, and the connection portion of at least a first end portion of the connection
member can engage with and disengage from the furniture items in a state where the
cushion portion is compressively deformed in a direction in which the two furniture
items adjacent to each other approach each other, and an engagement state of the connection
portion with respect to the furniture items is maintained in a state where the compressively
deformed cushion portion is deformed in a direction in which the cushion portion returns
to the original shape.
[0014] In the furniture system, in order to connect the two furniture items adjacent to
each other with the connection member, the two furniture items adjacent to each other
are pressed in a direction in which the two furniture items approach each other and
the cushion portion is compressively deformed. Accordingly, the connection portion
of at least a first end portion of the connection member can engage with the furniture
item.
[0015] In this way, after the connection portion of the connection member engages with the
furniture item, pressing between the furniture items is released. Therefore, the compressively
deformed cushion portion is deformed in the direction in which the cushion portion
returns to the original shape. As a result, the engagement state of the connection
portion with respect to the furniture items is maintained. Accordingly, the two furniture
items are connected to each other.
[0016] In addition, in order to release the connection between the two furniture items,
the two furniture items adjacent to each other are pressed in a direction in which
the two furniture items approach each other and the cushion portion is compressively
deformed. Accordingly, the connection portion of at least the first end portion of
the connection member can be disengaged from one of the furniture item.
[0017] In this way, it is possible to connect the furniture items to each other without
performing a bolt fastening operation.
[0018] In addition, an engagement member with which the connection member engages may be
provided on one of the furniture items adjacent to each other, the connection portion
may include an insertion portion into which the engagement member is inserted in a
state where the cushion portion is compressively deformed in the direction in which
the two furniture items adjacent to each other approach each other, and an engagement
portion which is formed to be continuous to the insertion portion, is open with respect
to the insertion portion in a direction in which the furniture items are separated
from each other, and engages with the engagement member.
[0019] According to this configuration, the engagement member can be inserted into the insertion
portion in the state where the cushion portion is compressively deformed in the direction
in which the two furniture items adjacent to each other approach each other. Accordingly,
the connection member can engage with and disengage from one of the furniture item.
[0020] Moreover, if the compressively deformed cushion portion is deformed in the direction
in which the cushion portion returns to the original shape, the engagement member
engages with the engagement portion, which is open in the direction in which the furniture
items are separated from each other, rather than with the insertion portion. Accordingly,
the engagement state of the connection member with respect to one of the furniture
items is maintained.
[0021] In addition, a second end portion of the connection member may be rotatably connected
to the other of the furniture items which is adjacent thereof.
[0022] According to this configuration, it is possible to connect the two furniture items
adjacent to each other by rotating the connection member.
[0023] In addition, in a state where the connection between the furniture items is released,
since the connection member is connected to the other of the two furniture items which
is adjacent thereof, it is not necessary to prepare a separate connection member.
[0024] The engagement member may include a displacement allowance portion which engages
with the furniture item in a state where the connection member can be displaced in
a height direction of the furniture item.
[0025] According to this configuration, even in a case where the height levels of the furniture
items adjacent to each other are different from each other due to unevenness of a
floor surface, it is possible to connect the furniture items to each other with the
connection member.
[0026] The furniture item may include a furniture main body, and a leg portion by which
the furniture main body stands on a floor surface, and the connection member may be
disposed on a lower surface of the furniture main body.
[0027] According to this configuration, a gap exists between the lower portion of the furniture
main body supported by the leg portion and the floor surface. Therefore, the connection
operation of the furniture items with the connection member can be easily performed
by allowing a hand to enter the gap between the furniture main body and the floor
surface.
[0028] The connection member may be disposed on a base portion of the leg portion.
[0029] Accordingly, it is possible to cause the furniture items adjacent to each other to
approach each other by gripping the leg portions of both furniture items. Therefore,
it is possible to easily perform the connection operation between the furniture items
with the connection member.
[0030] At least one of the furniture items adjacent to each other may be a sofa.
[0031] Accordingly, it is possible to easily and reliably connect a sofa in which the outer
surface has the cushion portion to other sofas or other furniture items.
Advantageous Effects of Invention
[0032] According to the furniture system of the present invention, it is possible to easily
and reliably connect furniture items to each other and prevent positional deviation
of the furniture items.

[0045] As shown in FIG. 4, the panel body 11 includes a panel base material (base material)
12, cushion materials (flexible materials) 13 which are provided on both surfaces
of the panel base material 12, skin materials 14 which cover the panel base material
12 and the cushion materials 13, and fixing members 30.
[0046] The panel body 11 is formed in a flat plate shape, an approximate L shape in which
an intermediate portion is bent or curved when viewed in a plan view or in a side
view, an approximate C shape in a plan view in which the entirety is curved, or the
like according to the shape of an installed appliance or the like. Hereinafter, a
case where the panel body 11 is formed in a flat plate shape is described.
(Panel Base Material)
[0047] The panel base material 12 includes a panel-shaped core material 15, a frame 20 which
is provided along the outer circumferential portion of the core material 15, and a
base sheet 18 which is provided so as to cover both surfaces of the core material
15 and the frame 20.
[0048] For example, the core material 15 is formed of a paper based material, a resin base
material, a wood based material, or the like. Preferably, the core material 15 is
as lightweight as possible. Accordingly, in the present embodiment, the core material
15 is formed of a paper based material, multiple holes 15h penetrating the core material
15 in a plate thickness direction are disposed in parallel, and for example, the core
material 15 has a honeycomb structure in which multiple holes 15h having hexagonal
cross-sections are combined in a staggered manner.
(Frame)
[0049] As shown in FIGS. 4 and 5, the frame 20 is provided on the outer circumferential
portion of the core material 15. The frame 20 includes frame materials 21 A, 21 B,
21 C, and 21 D which are provided along four sides of the core material 15. Each of
the frame materials 21A, 21B, 21C, and 21D is formed of a metal based material, a
resin based material, or the like.
[0050] The frame materials 21A and 21B extend in a vertical direction along two sides facing
each other in the core material 15 and are provided on both sides in the width direction
of the panel body 11. The frame materials 21C and 21 D extends in a horizontal direction
so as to be orthogonal to the frame materials 21A and 21B and are provided on both
sides in the vertical direction of the panel body 11. The frame materials 21 A and
21 B and the frame materials 21C and 21 D are joined to each other via L-shaped brackets
22 by bolts 23, welding, bonding, or the like. The frame 20 having a rectangular shape
as a whole is formed by the frame materials 21A, 21B, 21C, and 21D.
[0051] As shown in FIGS. 6 to 8, each of the frame materials 21A, 21B, 21C, and 21D is formed
in an approximately U-shaped cross-section which includes a base portion 21e which
faces an outer circumferential end surface 15a of the inner circumferential side core
material 15 of the frame 20, and side wall portions 21f which rises from both sides
in the width direction of the base portion 21 e toward the outer circumferential side
of the frame 20. Accordingly, a groove 25 is formed in a portion which is surrounded
by the base portion 21e, and both side wall portions 21f and 21f.
[0052] Meanwhile, the panel base material 12 is continuous along the outer circumferential
end portion thereof, and includes the groove 25 which is recessed toward the inner
portion of the panel base material 12.
[0053] Here, as shown in FIG. 5, in the L-shaped bracket 22, a first plate portion 22a which
is provided on the end portion of the frame material 21A or 21B along the frame material
21 A or 21B, a second plate portion 22b which is orthogonal to the first plate portion
22a and is provided on the end portion of the frame material 21C or 21D along the
frame material 21C or 21 D, and a rib portion 22c which is provided on the inside
in the bending direction of the L-shaped bracket 22 along the first plate portion
22a and the second plate portion 22b are integrally formed.
[0054] Female screw portions 29 are formed on the first plate portion 22a and the second
plate portion 22b of the L-shaped bracket 22. In addition, through holes 28 are formed
on each of the base portion 21e of the frame material 21A or 21B along the first plate
portion 22a of the bracket 22 and the base portion 21e of the frame material 21C or
21D along the second plate portion 22b at positions facing the female screw portions
29. The female screw portions 29 and the through holes 28 are optional member attachment
portions which attach various optional members exemplified below.
[0055] The rib portion 22c is orthogonal to the first plate portion 22a and the second plate
portion 22b from the first plate portion 22a and the second plate portion 22b and
is formed so as to protrude toward the inner circumferential side of the panel body
11. The rib portions 22c is formed on each of both sides in the width direction of
the first plate portion 22a and the second plate portion 22b, that is, each of a first
surface side and a second surface side of the panel body 11.
[0056] The rib portion 22c functions as not only a reinforced member which increases bending
strength of the first plate portion 22a and the second plate portion 22b but also
functions as a pressing member of corners of the core material 15. Accordingly, the
core material 15 is interposed between the rib portions 22c which are provided on
the first surface side and the second surface side of the panel base material 12.
That is, in the panel base material 12, the core material 15 can be held inside the
frame 20 by providing the brackets 22 on the four corners.
[0057] As shown in FIGS. 7 and 8, the sheet-shaped base sheets 18 are provided on both surfaces
of the core material 15 so as to cover the frame 20 and the core material 15. For
example, the base sheet 18 is formed of cardboard or the like. External dimensions
of the base sheet 18 are greater than those of the core material 15, and the outer
circumferential portion 18a of the base sheet 18 is bonded to the surface 20f of the
frame 20 by a bonding agent or the like.
(Cushion Material)
[0058] The cushion material 13 is provided along the base sheet 18 which forms the surface
of the panel base material 12. The cushion material 13 is provided so as to the entire
core material 15 via the base sheet 18. In addition, the cushion material 13 is provided
such that an outer circumferential end portion 13s of the cushion material 13 covers
a side wall portion 21f of each of the frame materials 21A, 21B, 21C, and 21D which
configure the frame 20. That is, the cushion material 13 is provided so as to cover
the core material 15 and the frame 20.
[0059] For example, the cushion material 13 is formed of a material having flexibility and
elasticity such as a foamed urethane material.
[0060] FIGS. 9A and 9B are sectional views showing the cushion material 13 which is provided
along the surface of the panel base material 12, FIG. 9A is a sectional view of the
cushion material 13 in a state where a skin material 14 is not mounted, and FIG. 9B
is a sectional view of a cushion material 13 in a state where the skin material 14
is mounted.
[0061] As shown in FIG. 4, multiple through holes 16 are formed in the cushion material
13. For example, each of the through holes 16 is formed in an elliptical shape which
has a vertical direction as a longitudinal direction. In addition, the multiple through
holes 16 are arranged on an outer surface 13f of the cushion material 13 at intervals
therebetween in the vertical direction and the horizontal direction orthogonal to
the vertical direction.
[0062] As shown in FIGS. 7, 9A, and 9B, each through hole 16 is formed to penetrate the
cushion material 13 in the thickness direction of the cushion material 13 from the
outer surface 13f facing the side opposite to the panel base material 12 in the cushion
material 13 to an opposing surface 13g facing the panel base material 12 side. As
shown in FIG. 9A, each through hole 16 is formed such that an inner circumferential
surface 16f of the through hole 16 is orthogonal to the outer surface 13f. Accordingly,
corners 16v are formed on the circumferential edges of the through holes 16.
[0063] By providing the cushion material 13 having the through holes 16 formed as described
above on the surface of the panel base material 12, uneven shapes having the corners
16v are formed on the surface of the panel base material 12.
(Skin Material)
[0064] As shown in FIGS. 7, 9A, and 9B, the skin material 14 is provided to cover the entire
cushion material 13. The skin material 14 is bonded along the outer surface 13f of
the cushion material 13, the inner circumferential surface 16f orthogonal to the outer
surface 13f in the through hole 16, and an exposed surface 18f of the base sheet 18
exposed to the bottom portion of the through hole 16. In this way, since the skin
material 14 is provided along the multiple through holes 16 formed in the cushion
material 13, multiple elliptical (uneven portions) recess portions 17 are formed on
the surface of the panel body 11. In addition, in each recess portion 17, the skin
material 14 is bonded to the base sheet 18 which forms the surface of the panel base
material 12 via the through hole 16.
[0065] Here, for example, the skin material 14 is formed of an elastically deformable material
such as polyester, and covers the cushion material 13 and the panel base material
12 in an extended state. In the cushion material 13, the corner 16v which protrudes
toward the outside in the circumferential edge of the through hole 16 on the outer
surface 13f is pressed toward the inside by the skin material 14. Accordingly, the
cushion material 13 is elastically deformed in a compression direction in the corner
16v, and the corner 16v of the through hole 16 has an arc-shaped cross section.
[0066] In addition, as shown in FIGS. 7 and 8, external dimensions of the cushion material
13 and the skin material 14 are greater than the external dimension of the panel base
material 12. In addition, the outer circumferential end portions 13e and 14e of the
cushion material 13 and the skin material 14 wrap around the outer circumferential
edge portion of the panel base material 12, that is, the side wall portion 21f of
each of the frame materials 21A, 21B, 21C, and 21D, and are rolled inside the groove
25. The cushion material 13 is compressed by the skin material 14 by the portion of
the side wall portion 21f of each of the frame materials 21A, 21B, 21C, and 21D wrapped
around by the outer circumferential end portions 13e and 14e of the cushion material
13 and the skin material 14. Accordingly, the panel body 11 is formed such that the
thickness thereof gradually decreases toward the outer circumferential end portion
11s. In addition, the panel body 11 is roundly formed in an arc shape by the portion
of the side wall portion 21f of each of the frame materials 21A, 21B, 21C, and 21D
wrapped around by the cushion material 13 and the skin material 14 in the outer circumferential
end portion 11s.
[0067] The cushion material 13 and the skin material 14 configure a skin structure.
(Fixing Member)
[0068] The fixing member 30 is fitted into the groove 25. The outer circumferential end
portions 13e and 14e of the cushion material 13 and the skin material 14 rolled into
the groove 25 are interposed between the inner circumferential surface of the groove
25 and the outer circumferential surface of the fixing member 30 by the fixing member
30. Accordingly, the outer circumferential end portions 13e and 14e of the cushion
material 13 and the skin material 14 are fixed to the side wall portion 21f of the
frame 20.
[0069] Here, as shown in FIG. 4, the fixing member 30 includes linear portion fixing members
30S which are disposed on linear portions 12S of the outer circumferential portion
of the rectangular panel base material 12, and corner portion fixing members 30C which
are disposed on corner portions 12C of the outer circumferential portion of the rectangular
panel base material 12.
[0070] As shown in FIG. 7, each of the linear portion fixing members 30S includes side plate
portions 31 and 31 in which sectional shapes thereof orthogonal to the direction in
which the linear portion fixing member 30S is continuous are parallel to each other,
and a connection plate portion 32 which integrally connects the side plate portions
31 and 31 to each other.
[0071] The outer circumferential end portions 13e and 14e of the cushion material 13 and
the skin material 14 are interposed between the side wall portions 21f configuring
the groove 25 of the frame 20 by the side plate portions 31 and 31. Accordingly, the
gap between the side plate portions 31 and 31 is formed to be smaller than the gap
of the side wall portions 21f and 21f of the groove 25 by predetermined dimensions.
The side plate portions 31 and 31 are formed such that distal end portions 31a and
31 a come into contact with the base portion 21e of the groove 25 when the linear
portion fixing member 30S is fitted into the groove 25.
[0072] The connection plate portion 32 is formed to be offset in a direction of being further
separated from the base portion 21e of the groove 25 relative to the distal end portions
31 a and 31 a of the side plate portions 31 and 31. Accordingly, the linear portion
fixing member 30S has an approximately H-shaped cross section formed by the side plate
portions 31 and 31 and the connection plate portion 32. In addition, in a state where
the linear portion fixing member 30S is fitted into the groove 25, a space S1 is formed
in a portion which is surrounded by the distal end portions 31a and 31a sides of the
side plate portions 31 and 31, the connection plate portion 32, and the base portion
21e of the groove 25. The space S1 functions as an accommodation space which can accommodate
surplus portions of the outer circumferential end portions 13e and 14e of the cushion
material 13 and the skin material 14 rolled into the groove 25, that is, distal end
portions (not shown) rather than the portions which come into contact with the base
portion 21e of the frame 20 in the outer circumferential end portions 13e and 14e.
[0073] In addition, protrusions 33 and 33 are formed on sides facing the side wall portions
21f and 21f of the groove 25 in the side plate portions 31 and 31. The protrusions
33 and 33 are bitten into the outer circumferential end portions 13e and 14e of the
cushion material 13 and the skin material 14 which are interposed between the side
plate portions 31 and 31 and the side wall portions 21f and 21f. Accordingly, the
linear portion fixing member 30S prevents the cushion material 13 and the skin material
14 from being extracted from the groove 25.
[0074] In addition, in the side plate portions 31 and 31, protrusion pieces 34 and 34 which
protrude inside from the side plate portions 31 and 31 are formed on sides further
separated from the base portion 21e of the groove 25 relative to the connection plate
portion 32. In addition, a holding groove 35 is formed, which is surround by the protrusion
pieces 34 and 34, the side plate portions 31 and 31, and the connection plate portion
32 and serves as an optional member attachment portion.
[0075] As shown in FIG. 5, the corner portion fixing member 30C which is disposed on the
upper corner portion of the panel body 11 is formed in an approximately L shape which
includes a first linear portion 38A which vertically extends, and a second linear
portion 38B which is bent from the upper end of the first linear portion 38A and horizontally
extends.
[0076] The first linear portion 38A is fitted into the groove 25 on the upper end portion
of the frame material 21A or the frame material 21B which vertically extends. The
second linear portion 38B is formed so as to be continuous from one end of the first
linear portion 38A, and is fitted into the groove 25 on both end portions of the frame
material 21C or the frame material 21 D. In this way, the groove 25 is continuously
formed on the upper surface and both side surfaces of the base material 21, and the
corner portion fixing member 30C is provided on the portion in which the upper surface
groove 25 and both side surface grooves 25 are continuous to each other.
[0077] As shown in FIG. 8, each of the first linear portion 38A and the second linear portion
38B includes side plate portions 36 and 36 in which sectional shapes thereof orthogonal
to the directions in which the first and second linear portions 38A and 38B are continuous
are parallel to each other, and a connection plate portion 37 which integrally connects
the side plate portions 36 and 36 to each other.
[0078] The outer circumferential end portions 13e and 14e of the cushion material 13 and
the skin material 14 are interposed between the side wall portions 21 f and 21f configuring
the groove 25 of the frame 20 by the side plate portions 36 and 36. Accordingly, the
gap between the side plate portions 36 and 36 is formed to be smaller than the gap
of the side wall portions 21f and 21f of the groove 25 by predetermined dimensions.
The side plate portions 36 and 36 are formed such that distal end portions 36a and
36a come into contact with the base portion 21e of the groove 25 when the corner portion
fixing member 30C is fitted into the groove 25.
[0079] Herein, in the side plate portions 36 and 36, protrusion portions 36t and 36t are
formed on the sides facing the side wall portions 21f and 21f of the groove 25. The
outer circumferential end portions 13e and 14e of the cushion material 13 and the
skin material 14 are interposed between the side plate portions 31 and 31 and the
side wall portions 21f and 21f by the protrusion portions 36t and 36t.
[0080] The connection plate portion 37 is formed to be offset in a direction of being further
separated from the base portion 21e of the groove 25 relative to the distal end portions
36a and 36a of the side plate portions 36 and 36. Accordingly, the corner portion
fixing member 30C has an approximately H-shaped cross section formed by the side plate
portions 36 and 36 and the connection plate portion 37. In addition, in a state where
the linear portion fixing member 30S is fitted into the groove 25, a space S2 is formed
in a portion which is surrounded by the distal end portions 36a and 36a sides of the
side plate portions 36 and 36, the connection plate portion 37, and the base portion
21e of the groove 25. The space S2 functions as an accommodation space which can accommodate
surplus portions of the outer circumferential end portions 13e and 14e of the cushion
material 13 and the skin material 14 rolled into the groove 25, that is, distal end
portions (not shown) rather than the portions which come into contact with the base
portion 21e of the frame 20 in the outer circumferential end portions 13e and 14e.
In addition, here, the connection plate portion 37 is closer to the base portion 21e
in the linear portion fixing member 30S relative to the connection plate portion 32,
and thus, the space S2 is formed to be smaller than the space S 1.
[0081] As shown in FIG. 5, the corner portion fixing member 30C is fixed to the groove 25
by a corner cap 40. The corner cap 40 is formed in an approximately L shape which
includes a first linear portion 41 A, and a second linear portion 41 B which is continuous
to one end of the first linear portion 41A and extends so as to be orthogonal to the
first linear portion 41A. As shown in FIG. 8, the first linear portion 41A and the
second linear portion 41B are inserted into a portion between the side plate portions
36 and 36 with respect to the first linear portion 38A and the second linear portion
38B of the corner portion fixing member 30C, and come into contact with the connection
plate portion 37.
[0082] In addition, as shown in FIG. 5, a protrusion piece 43 is formed on the lower end
portion of the first linear portion 41A so as to protrude toward the lower portion.
The protrusion piece 43 is inserted into the holding groove 35 (refer to FIG. 7) between
the connection plate portion 32 and the protrusion piece 34 on the upper end portion
of the linear portion fixing member 30S.
[0083] In addition, as shown in FIG. 5, a bolt insertion hole 44 into which a bolt 45 is
inserted is formed on the second linear portion 41B. The corner cap 40, the corner
portion fixing member 30C, the frame material 21C, and the second plate portion 22b
of the bracket 22 are integrally fastened to each other by the bolt 45 inserted into
the bolt insertion hole 44.
(Support Leg Body)
[0084] As shown in FIG. 5, as described above, each support leg body 50 is provided on each
corner portion of both end portions of the lower portion of the panel body 11. Since
the support leg body 50 is in contact with a floor surface, the panel body 11 is erected
on the floor surface.
[0085] The support leg body 50 integrally includes a lower support portion 51 which is accommodated
in the groove 25 by a lower end portion 12P of the panel base material 12, a side
support portion 52 which extends upward from the one end of the lower support portion
51 and is accommodated in the groove 25 by a side lower end portion 12Q of the panel
base material 12, and a support leg portion 53 which further extends downward relative
to the lower support portion 51.
[0086] The lower support portion 51 comes into contact with the base portion 21e which forms
the lower surface of the groove 25 on the lower end portion of the frame 20 and is
fixed to the base portion 21e. In addition, the side support portion 52 comes into
contact with the base portion 21 e which forms the bottom surface of the groove 25
on the side end portion of the frame 20 and is fixed to the base portion 21e.
[0087] Bolt insertion holes 54 into which bolts 48 are inserted are formed in the lower
support portion 51 and the side support portion 52. The bolts 48 which are inserted
into the bolt insertion holes 54 are screwed into the female screw portions 29 and
the through holes 28. Accordingly, the support leg body 50 is fixed to the panel body
11.
[0088] The support leg portion 53 extends further downward relative to the lower support
portion 51, and a height adjustment screw 49 can be screwed into the lower end portion
of the support leg portion 53.
(Connection Structure between Sofa and Panel Body)
[0089] FIG. 10 is a side view showing a connection portion of the panel body 11 with respect
to the upper portion of the back rest plate 108 of the sofa. FIG. 11 is a sectional
view showing a structure of a connection portion between the sofa 101 and the panel

[0093] A bolt 179, which is inserted from the through hole 172A, is screwed with a base
portion 178 which is provided inside the holding groove 35 of the linear portion fixing
member 30S fixed to the frame material 21A (or frame material 21B) of the panel body
11 and in which a female screw is formed. In this way, in a state where the appliance
upper connection bracket 171 is attached to the panel body 11, the upper portion of
the back rest plate 108 of the sofa 101 is interposed between the holding wall portion
175 and the front wall portion 177 of the appliance upper connection bracket 171.
[0094] At this time, the cushion material 13P of the side, on which the outer wall portion
174 of the appliance upper connection bracket 171 is disposed in the panel body 11,
is pressed by the outer wall portion 174. Accordingly, the width dimension of the
cushion material 13P of the side on which the appliance upper connection bracket 171
is disposed is smaller than the width dimension of the cushion material 13Q of the
side on which the appliance upper connection bracket 171 is not disposed. In addition,
the end portion of the cushion material 13Q is flush with the end surface of the outer
wall portion 174 of the appliance upper connection bracket 171 which is disposed along
the cushion material 13P.
[0095] As shown in FIGS. 3 and 13, the upper portion of the sofa 101 and the lower portion
of the panel body 11 are connected to each other via the appliance lower connection
bracket 181.
[0096] The appliance lower connection bracket 181 includes a support wall portion 182 which
is fixed to the base plate 105 of the leg portion 103 attached to the lower surface
of the seat surface portion 102 of the sofa 101 by the bolt (not shown), and a bending
wall portion 183 which is bent downward from the end portion of the support wall portion
182. The appliance lower connection bracket 181 includes a vertical wall portion 184
which is bent from the end portion of the bending wall portion 183 and is disposed
along the skin material 14 of the panel body 11, a lower wall portion 185 which is
bent from the lower end of the vertical wall portion 184 and extends toward the bent
panel body 11 side, and a lock portion 186 which extends upward from the end portion
of the lower wall portion 185. A rib 186A, which has a width corresponding to the
gap between the side plate portions 31 and 31 of the linear portion fixing member
30S of the lower end portion of the panel body 11, is formed on the lock portion 186.
[0097] The lock portion 186 of the appliance lower connection bracket 181 is inserted into
the portion between the side plate portions 31 and 31 of the linear portion fixing
member 30S of the lower end portion of the panel body 11so as to be locked.
[0098] In this way, the panel body 11 is mounted to the rear of the back rest plate 108
via the appliance upper connection bracket 171 and the appliance lower connection
bracket 181.
(Connection between Sofas)
[0099] Next, in the above-described sofa system 100, in the sofas 101 and 101 adjacent to
each other, all the leg portions 103 and 103, and all the panel bodies 11 and 11 of
the sofas 101 are connected to each other according to the following manner.
(Connection between Panel Body Lower Portions by Support Leg Bodies)
[0100] FIG. 14 is a perspective view showing an example of a connection structure in a support
leg bodies 50 which are provided on corners of the lower portions of the panel bodies
11. FIG. 15 is a sectional view showing a connection structure of the lower portions
of the panel bodies 11 and 11.
[0101] As shown in FIGS. 14 and 15, one end of a lower connection member 55 for connecting
the panel body 11 and another panel body 11 disposed to be adjacent to the panel body
can be locked to the support leg body 50. Accordingly, a bulged portion 56 which is
bulged further downward relative to the lower support portion 51 is integrally formed
in the support leg body 50.
[0102] In the bulged portion 56, a slit 57 into which one end of the plate-shaped lower
connection member 55 can be inserted is formed on the intermediate portion of the
support leg body 50 along the thickness direction of the panel body 11.
[0103] The slit 57 is open to the side surface 56a and the lower surface 56b on the side
of the bulged portion 56 adjacent to another panel body 11.
[0104] As shown in FIG. 15, an insertion recess portion 57a, into which a protrusion portion
58A of the lower connection member 55 described below is inserted, is formed on the
upper portion of the slit 57 to be recessed upward. In addition, in the upper portion
of the slit 57, a protrusion portion 57b which is adjacent to the insertion recess
portion 57a and protrudes downward is formed on the side surface 56a side of the bulged
portion 56.
[0105] In addition, in the bulged portion 56, a locking hole 56h for locking the lower connection
member 55 inserted into the slit 57 is formed to penetrate the panel body 11 in the
thickness direction of the panel body 11.
[0106] Through holes 55h are formed on both end portions of the lower connection member
55. In addition, the protrusion portions 58A protruding upward are formed on both
end portions of the lower connection member 55. Moreover, in the lower connection
member 55, a center protrusion portion 58B protruding upward is formed between the
protrusion portions 58A and 58A of both end portions. In addition, engagement recess
portions 58C which is recessed downward are formed between the center protrusion portion
58B and both protrusion portions 58A.
[0107] In the protrusion portion 57b and the engagement recess portion 58C, the side surface
56a side of the bulged portion 56 and the center protrusion portion 58B side become
vertical surfaces 57f and 58f which vertically extend, and the opposite sides becomes
inclined surfaces 57g and 58g which are separated from the vertical surfaces 57f and
58f toward the upper portion. Accordingly, each of the protrusion portions 57b and
the engagement recess portions 58C has a taper shape in which the width dimension
gradually decreases toward the lower portion.
[0108] By fitting the protrusion portions 57b of the slits 57 into the engagement recess
portions 58C, the lower connection member 55 and the support leg bodies 50 easily
positioned in the direction in which the panel bodies 11 and 11 are adjacent to each
other.
[0109] In order to connect the panel bodies 11 and 11 adjacent to each other, both end portions
of the lower connection member 55 in which through holes 55h are formed are inserted
into the slits 57 of the support leg bodies 50. The protrusion portions 57b of the
support leg bodies 50 which are provided on both panel bodies 11 are fitted into the
engagement recess portions 58C on both end portions of the lower connection member
55. Here, each of the protrusion portions 57b and the engagement recess portions 58C
has a taper shape in which the width dimension gradually decreases toward the lower
portion. Accordingly, the protrusion portions 57b are inserted into the engagement
recess portions 58C, and thus, the lower connection member 55 and the support leg
bodies 50 easily positioned in the direction in which the panel bodies 11 and 11 are
adjacent to each other. Therefore, the through holes 55h formed on both end portions
of the lower connection member 55 communicate with the locking holes 56h of the support
leg bodies 50. Thus, the connection bolts 59 are inserted into the through holes 55h
and the locking holes 56h so as to be fastened. Accordingly, the lower end portions
of the panel bodies 11 and 11 are connected to each other by the lower connection
member 55.
(Connection between Panel Body Upper Portions)
[0110] FIG. 16 is a perspective view showing an example of the connection structure of the
upper portions of the panel bodies 11 and 11.
[0111] As shown in FIG 16, it is possible to connect the upper end portions of the panel
bodies 11 and 11 adjacent to each other by an upper connection member 61 serving as
an optional member.
[0112] Instead of the corner caps 40, the upper connection member 61 is attached to the
corner portion fixing member 30C. Bolt insertion holes 62 are formed on both end portions
61 a and 61a of the upper connection member 61.
[0113] In addition, a gap regulation portion 63 is formed so as to protrude downward on
the lower surface side of an intermediate portion 61b of the upper connection member
61, and the gap regulation portion 63 regulates the gap between the corner portion
fixing members 30C and 30C disposed on the upper portions of the panel bodies 11 and
11 adjacent to each other. The gap regulation portion 63 is inserted into the portion
between the corner portion fixing members 30C and 30C which are disposed on the upper
portions of the panel bodies 11 and 11 adjacent to each other, and thus, it is possible
to regulate the gap between the panel bodies 11 and 11.
[0114] In order to connect the upper end portions of the panel bodies 11 and 11 to each
other with the upper connection member 61, the following manner is performed.
[0115] First, the upper connection member 61 is placed on the corner portion fixing members
30C and 30C which are disposed on the upper portions of the panel bodies 11 and 11
adjacent to each other. At this time, the lower surfaces of both end portions 61 a
and 61a of the upper connection member 61 are inserted into the portion between the
side plate portions 36 and 36 with respect to the second linear portion 38B of the
corner portion fixing member 30C, and come into contact with the connection plate
portions 37. In addition, since the gap regulation portion 63 can be inserted into
the portion between the corner portion fixing members 30C and 30C disposed on the
upper portions of the panel bodies 11 and 11 adjacent to each other, it is possible
to regulate the gap between the panel bodies 11 and 11. More specifically, since the
connection plate portions 37 of the first linear portions 38A of the corner portion
fixing members 30C come into contact with both side surfaces 63a and 63a of the gap
regulation portion 63, it is possible to appropriately position the gap between the
panel bodies 11 and 11. In this state, bolts 64 inserted into the bolt insertion holes
62 are fastened to the female screw portions 29 through the through holes 28, and
thus, the upper connection member 61, the corner portion fixing members 30C, the frame
material 21C (refer to FIG. 5), and the second plate portions 22b (refer to FIG. 5)
of the bracket 22 are integrally fixed. Accordingly, the upper end portions of the
panel bodies 11 and 11 adjacent to each other are connected to each other.
(Connection between Leg Portions on Front Portion of Sofa)
[0116] FIG. 17 is a front view showing a connection portion of the leg portions 103 and
103 on the front portions of the sofas 101 and 101 adjacent to each other. FIG. 18
is a plane view showing a connection plate 200.
[0117] FIG. 19 is a side view showing an engagement member 210. FIGS. 20A and 20B is a view
showing a flow when the leg portions 103 and 103 of the sofas 101 and 101 adjacent
to each other are connected to each other, FIG. 20A is a view showing a state before
the connection plate 200 is rotated, and FIG. 20B is a view showing a state immediately
before a connection portion 201 of the connection plate 200 engages with the engagement
member 210. FIG. 21 is a view showing a state where the connection portion 201 of
the connection plate 200 engages with the engagement member 210 so as to connect the
sofas 101 and 101 to each other.
[0118] As shown in FIG. 17, in the soft system 100, in the sofas 101 and 101 adjacent to
each other, the leg portions 103 and 103 provided on the front end sides of the seat
surface portions 102 are connected to each other by the connection plate 200.
[0119] As shown in FIG. 18, the connection plate 200 is formed of an elliptical metal plate.
[0120] The connection plate 200 includes the connection portion 201 and a connection hole
(connection portion) 205 serving as connection portions connected to the sofas 101
on both end portions of the connection plate 200. The connection portion 201 is formed
on the first end portion of the connection plate 200 and is connected to one sofa
101. The connection hole 205 is formed to penetrate the connection plate 200 on the
second end portion of the connection plate 200, and is rotatably connected to the
other sofa 101.
[0121] The connection portion 201 includes an insertion portion 202 which is open to a side
200s extending in the longitudinal direction of the connection plate 200, and an engagement
portion 203 which is formed so as to be continuous to the insertion portion 202.
[0122] The insertion portion 202 has an opening width which is greater than an outer diameter
of a shaft portion 210c (refer to FIG. 17) described below of the engagement member
210. The insertion portion 202 extends along a lateral direction of the connection
plate 200 from the side 200s of the connection plate 200.
[0123] The engagement portion 203 is formed in the intermediate portion in the lateral direction
of the connection plate 200. The engagement portion 203 has an inner diameter which
is greater than the shaft portion 210c of the engagement member 210. The engagement
portion 203 is formed so as to be offset toward the side separated from the connection
hole 205 with respect to the insertion portion 202. Accordingly, in the engagement
portion 203, an engagement recess portion 203a is formed, which is enlarged toward
the side separated from the connection hole 205 with respect to the insertion portion
202.
[0124] As shown in FIG. 17, by fastening a screw 206 penetrating the connection hole 205
to the base plate 105 of the leg portion 103, the connection plate 200 is rotatable
in the inner surface along the lower surface 102f of the seat surface portion 102
with the screw 206 as a center.
[0125] The engagement member 210 which engages with the connection plate 200 is provided
on one of the sofas 101 adjacent to each other. As shown in FIG. 19, the engagement
member 210 is a so-called stepped screw, and includes a screw head portion 210a which
is provided on a first end side, a male screw portion 210b which is provided on a
second end side, and a shaft portion 210c which is formed between the screw head portion
210a and the male screw portion 210b and has an grater outer diameter than that of
the male screw portion 210b.
[0126] As shown in FIG. 17, in the engagement member 210, the male screw portion 210b is
screwed into the base plate 105 of the leg portion 103 which is provided on the lower
surface of the seat surface portion 102 of the sofa 101. Accordingly, the shaft portion
210c of the engagement member 210 comes into contact with the base plate 105, and
the screw head portion 210a is positioned at a gap below the base plate 105 by the
length in the axial direction of the shaft portion 210c.
[0127] In the connection plate 200, the shaft portion (displacement allowance portion) 210c
of the engagement member 210 enters the insertion portion 202 of the connection portion
201 and engages with the engagement portion 203, and thus, the sofas 101 and 101 adjacent
to each other are connected to each other.
[0128] Here, the engagement member 210 can be inserted into the insertion portion 202 of
the connection portion 201 in a state where the cushion portion 102c is compressively
deformed in the direction in which two sofas 101 and 101 adjacent to each other approach
each other.
[0129] Accordingly, in the sofa system 100, in order to connect the sofas 101 and 101 adjacent
to each other with the connection plate 200, as shown in FIGS. 20A and 20B, the connection
member 200 rotates about the screw 206, and the shaft portion 210c of the engagement
member 210 is received into the connection portion 201. At this time, even in a state
where the sofas 101 and 101 only come into contact with each other, as shown in FIG.
20B, the insertion portion 202 of the connection portion 201 interferes with the shaft
portion 210c of the engagement member 210. Accordingly, as shown in FIG. 21, the cushion
portions 102c are compressively deformed in the direction in which two sofas 101 and
101 adjacent to each other approach each other. Preferably, the cushion portions 102c
are pressed in the direction two sofas 101 and 101 adjacent to each other approach
each other. Therefore, the engagement member 210 can be inserted into the engagement
portion 203 through the insertion portion 202 of the connection portion 201 on the
first end portion of the connection plate 200.
[0130] In addition, after the connection portion 201 of the connection plate 200 engages
with the sofa 101, the pressing between sofas 101 and 101 is released. Accordingly,
the cushion portions 102c are deformed in a direction in which the cushion portions
102c return to the original shapes by repulsive forces of the compressively deformed
cushion portions 102c. As a result, the engagement member 210 engages with the engagement
recess portion 203a of the engagement portion 203 of the connection portion 201. Accordingly,
in the connection portion 201 on first end side of the connection plate 200, the engagement
state with respect to the sofa 101 is maintained. In this way, two sofas 101 and 101
adjacent to each other are connected.
[0131] In addition, as shown in FIG. 20B, in order to release the connection between the
two sofas 101 and 101 performed by the connection plate 200, the cushion portions
102c which are pressed in the direction in which the two sofas 101 and 101 adjacent
to each other approach each other are compressively deformed. Accordingly, the shaft
portion 210c of the engagement member 210 is displaced from the state of entering
the engagement recess portion 203a of the engagement portion 203 so as to engage with
the engagement portion 203 to a position at which the shaft portion 210c communicates
with the insertion portion 202. In this state, as shown in FIG. 20A, if the connection
plate 200 rotates about the connection hole 205, the shaft portion 210c of the engagement
member 210 is extracted from the insertion portion 202. In this way, it is possible
to disengage the connection portion 201 on the first end portion of the connection
plate 200 from the sofas 101.
[0132] Here, as shown in FIG. 17, the length in the axial direction of the shaft portion
210c of the engagement member 210 is set so as to be greater than the thickness of
the connection plate 200. Accordingly, the connection portion 201 of the connection
plate 200 can engage with the shaft portion 210c of the engagement member 210 in a
state capable of being displaced in the height direction of the sofa 101.
[0133] As described above, in the sofa system 100, the sofas 101 and 101 adjacent to each
other are connected by the connection plate 200. In addition, the connection portion
201 on the first end portion of the connection plate 200 can engage with and disengage
from the sofa 101 in the state where the cushion portions 102c are compressively deformed
in the direction in which the two sofas 101 and 101 adjacent to each other approach
each other, and the engagement state of the connection portion 201 with respect to
the sofa 101 is maintained in which the compressively deformed cushion portions 102c
are deformed in the direction in which the cushion portions 102c return to the original
shapes.
[0134] Accordingly, in the case where the two sofas 101 and 101 adjacent to each other are
connected to each other by the connection plate 200, it is possible to allow the connection
portion 201 to engage with the sofa 101 in the state where the cushion portion 102c
is compressively deformed in the direction in which the two sofas 101 and 101 adjacent
to each other approach each other. In addition, after the connection portion 201 engages
with the sofa 101, the pressing between the sofas 101 and 101 is released. Accordingly,
the compressively deformed cushion portions 102c are deformed in the direction in
which the cushion portions 102c return to the original shapes, and the engagement
state of the connection portion 201 with respect to the sofa 101 is maintained. Therefore,
the two sofas 101 and 101 are connected to each other.
[0135] In addition, in order to release the connection between the two sofas 101 and 101,
if the two sofas 101 and 101 adjacent to each other are pressed in the direction in
which the sofas 101 and 101 approach each other and the cushion portion 102c is compressively
deformed, it is possible to disengage the connection portion 201 of the connection
plate 200 from the sofa 101.
[0136] In this way, it is possible to easily and reliably connect the sofas 101 and 101
to each other and prevent the positional deviation of the sofa 101.
[0137] Moreover, the engagement member 210 with which the connection plate 200 engages is
provided in one of the sofas 101 adjacent to each other, and the connection portion
201 includes the insertion portion 202 into which the engagement member 210 is inserted
in the state where the cushion portions 102c are compressively deformed in the direction
in which the two sofas 101 and 101 adjacent to each other approach each other, and
the engagement portion 203 which is formed so as to be continuous to the insertion
portion 202, is further enlarged in the direction, in which the cushion portions 102c
returns to the original shapes, relative to the insertion portion 202, and with which
the engagement member 210 engages.
[0138] According to this configuration, since the engagement member 210 is inserted into
the insertion portion 202 in the state where the cushion portions 102c are compressively
deformed in the direction in which the two sofas 101 and 101 adjacent to each other
approach each other, the connection portion 201 can engage with and disengage from
one of the sofa 101.
[0139] In addition, if the compressively deformed cushion portions 102c are deformed in
the direction in which the cushion portions 102c return to the original shapes, the
engagement member 210 engages with the engagement portion 203 which is further enlarged
in the direction in which the cushion portions 102c return to the original shapes
relative to the insertion portion 202. Accordingly, the engagement state with respect
to one of the sofa 101 is maintained.
[0140] In addition, the connection hole 205 on the second end portion of the connection
plate 200 is rotatably connected to the other of the sofas 101 which is adjacent thereof.
[0141] According to this configuration, by rotating the connection plate 200, it is possible
to easily connect the two sofas 101 and 101 adjacent to each other.
[0142] In addition, even in the state where the connection between the sofas 101 and 101
is released, since the connection plate 200 is connected to the other of the sofas
101 which is adjacent thereof, it is not necessary to prepare the separate connection
plate 200.
[0143] In addition, in the engagement member 210, the shaft portion 210c has a constant
length in the vertical direction, and the connection plate 200 engages with the shaft
portion 210c in the state where the connection plate 200 can be displaced in the height
direction of the sofa 101. According to this configuration, even in a case where the
height levels of the sofas 101 and 101 adjacent to each other are different from each
other due to unevenness of the floor surface, it is possible to connect sofas 101
and 101 to each other by the connection plate 200.
[0144] Moreover, the sofa 101 includes the seat surface portion 102, and the leg portion
103 by which the seat surface portion 102 stands on the floor surface, and the connection
plate 200 is provided on the lower surface of the seat surface portion 102.
[0145] According to this configuration, a gap exists between the lower portion of the seat
surface portion 102 supported by the leg portion 103 and the floor surface. Therefore,
the connection operation between the sofas 101 and 101 with the connection plate 200
can be easily performed by allowing a hand to enter the gap between the seat surface
portion 102 and the floor surface.
[0146] In addition, the connection member 200 is disposed on the base portion of the leg
portion 103. Accordingly, it is possible to approach the sofas 101 and 101 adjacent
to each other by gripping both leg portions 103 and 103. Therefore, it is possible
to easily perform the connection operation between the sofas 101 and 101 with the
connection plate 200.
[0147] Moreover, the seat surface portions 102 and 102 of the sofas 101 and 101 adjacent
to each other are connected to each other by the connection plate 200 in the state
where the cushion portions 102c and 102c are pressed to each other.
[0148] Accordingly, the seat surface portions 102 and 102 come into close contact with each
other without deviation therebetween, and it is possible to improve the appearance.
[0149] Moreover, since the seat surface portions 102 and 102 come into close contact with
each other, it is possible to prevent an article or the like from falling on the gap
between the seat surface portions 102 and 102.
[0150] In addition, in the above-described sofa system 100, the panel bodies 11 and 11 mounted
on the back rest plates 108 and 108 are connected to each other between the sofas
101 and 101 adjacent to each other.
[0151] Accordingly, it is possible to connect the rear portions of the sofas 101 and 101
to each other.
[0152] Here, according to the above-described panel body 11, the skin material 14 covering
the panel base material 12 and the cushion material 13 wraps around the outer circumferential
edge portion of the panel base material 12 on the outer circumferential portion of
the panel body 11 and is rolled into the groove 25. Therefore, the outer circumferential
portion of the panel body 11 is covered with the skin material 14 in the state where
the panel base material 12 is not exposed.
[0153] In addition, since the skin material 14 is fixed into the groove 25 by the fixing
member 30, it is possible to prevent the fixing member 30 from being exposed to the
outer circumferential portion of the panel body 11.
[0154] Accordingly, the outline of the panel body 11 can be a soft and systematic impression.
