Abstract
Description
- The present invention relates to a furniture system which includes multiple furniture items such as sofas.
- Priority is claimed on Japanese Patent Application No.
2014-017383, filed January 31, 2014 - 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.
- 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.
- 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.
- 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. - [Patent Document 1] Japanese Unexamined Patent Application, First Publication No.
2013-94405 - However, bolt-tightening the connection metal fitting takes much labor.
- 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.
- 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. - 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.
- The present invention adopts the following means in order to solve the above-described problems.
- 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.
- 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.
- 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.
- 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.
- In this way, it is possible to connect the furniture items to each other without performing a bolt fastening operation.
- 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.
- 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.
- 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.
- 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.
- According to this configuration, it is possible to connect the two furniture items adjacent to each other by rotating the connection member.
- 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.
- 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.
- 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.
- 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.
- 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.
- The connection member may be disposed on a base portion of the leg portion.
- 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.
- At least one of the furniture items adjacent to each other may be a sofa.
- 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.
- 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.
