従来、バネ機構を用いずに発泡ポリウレタンなどのクッション性を有する合成樹脂やゴム素材を用いて座部及び背もたれを構成したソファーは知られている。
しかしながら、クッション性を有する素材のみでソファーを構成した場合、特に背もたれ部分の保形成に難があり、長期間の使用により背もたれ部分が変形し易いという問題点がある。
However, when the sofa is made of only a material having cushioning properties, there is a problem in that it is difficult to form the backrest part in particular, and the backrest part is easily deformed by long-term use.
上記特許文献に開示された発明は、上記問題点を解決するための提案であって、クッション体の背もたれ部の裏面近傍に補強板を挿入したものである。
しかしながら、この発明においては補強板を立設保持するための配慮が払われておらず、長期間の使用に適したものとはいえない。また、クッション体の座部と背もたれ部とは一体成型されるものであって、成型用の型が大型となりコストも嵩む。
The invention disclosed in the above-mentioned patent document is a proposal for solving the above-mentioned problems, and is a structure in which a reinforcing plate is inserted in the vicinity of the back surface of the backrest portion of the cushion body.
However, in the present invention, no consideration is given to standing and holding the reinforcing plate, and it cannot be said that it is suitable for long-term use. Further, the seat portion and the backrest portion of the cushion body are integrally molded, and the molding die becomes large and the cost increases.
この発明は、上記発明における補強板を立設保持するための構成を備え、長期間の使用においてもクッション体の背もたれ部が変形しないようにすることを第一の課題とし、クッション体の座部と背もたれ部とを別部材として製造コストを軽減することを第二の課題とするものである。 This invention is provided with the structure for standingly holding the reinforcing plate in the above invention, and a first object is to prevent the backrest portion of the cushion body from being deformed even after long-term use. The second problem is to reduce the manufacturing cost by using the backrest and the backrest as separate members.

The support 1 is made of polypropylene, and is configured by attaching a back support 3 to a seat support 2.
The seat support 2 is provided with three receiving grooves 5 for mounting the back support 3 along two adjacent edges of a base 4 that is a flat rectangular parallelepiped. A flange 6 is formed on the lower peripheral edge of the pedestal 4 over the entire circumference, and a rising portion 7 is formed on the outer edge of the flange 6 over the entire circumference.
The backrest support portion 2 has a slightly curved flat plate shape, and three convex portions 8 that fit into the receiving grooves 5 are formed in the lower portion. Further, reinforcing ribs 9 are formed in the vertical direction.
The support 1 is configured by fitting the convex portion 8 of the backrest support portion 3 into the receiving groove 5 of the seat support portion 2 configured as described above.
In the case of obtaining a corner sofa, by attaching the back support portion 3 to the receiving groove 5 formed on the unused edge of the pedestal 4, the sofa can be provided with a backrest in a bowl shape.
クッション体１１は発泡ポリウレタン製であって、一人用の座部１２と背もたれ部１３とで構成してある。
前記座部１２は底部に前記座部支持部２の台座３に嵌る凹部１４が形成してあり、この凹部１４の後部に前記背もたれ支持部３に嵌る横長の溝１５が上下貫通して形成してある。また、座部１２の底面外周部には、前記座部支持部１２に形成された立ち上がり部６が装着される細溝１６が環状に形成してある。
座部１２の表面後部は背もたれ部１３と安定して当接するように水平な平面としてある。図中符号１８はアームレストである。
前記背もたれ部１３の幅ほぼ中央部には、下面から上部に亘り、前記背もたれ支持部３に嵌る溝１７が形成してある。
The cushion body 11 is made of polyurethane foam, and is composed of a seat 12 for one person and a backrest 13.
The seat portion 12 is formed with a recess 14 that fits in the base 3 of the seat support portion 2 at the bottom, and a laterally long groove 15 that fits in the back support portion 3 is formed in the rear portion of the recess 14 so as to penetrate vertically. It is. In addition, a narrow groove 16 in which the rising portion 6 formed on the seat support portion 12 is mounted is formed in an annular shape on the outer peripheral portion of the bottom surface of the seat portion 12.
The rear surface portion of the seat portion 12 is a horizontal plane so as to come into stable contact with the backrest portion 13. Reference numeral 18 in the figure denotes an armrest.
A groove 17 that fits into the backrest support portion 3 is formed in a substantially central portion of the width of the backrest portion 13 from the lower surface to the upper portion.
上記のように構成された支持体１とクッション体１１を用いてソファーを組み立てる手順は以下のとおりである。
初めに 座部支持部２の台座４に形成された受け溝５に背もたれ支持部３の凸部８を嵌装して支持体１を構成する。次いで、クッション体１１の座部１２を、その溝１５を前記背もたれ支持部３に嵌め込みつつ下方に押し込み、座部１２の下面に形成された凹部１４を台座４に嵌装し、更に座部１２の下面に形成された細溝１６を座部支持部２に形成された立ち上がり部７に押し込む。
次いで、背もたれ部１３をその溝１７を前記背もたれ支持部３に嵌め込みつつ下方に押し込み、その下面を前記座部１２の後部表面に当接させる。
The procedure for assembling the sofa using the support body 1 and the cushion body 11 configured as described above is as follows.
First, the support 1 is configured by fitting the convex portion 8 of the backrest support portion 3 into the receiving groove 5 formed in the base 4 of the seat support portion 2. Next, the seat portion 12 of the cushion body 11 is pushed downward while fitting the groove 15 into the backrest support portion 3, and the concave portion 14 formed on the lower surface of the seat portion 12 is fitted into the pedestal 4. The narrow groove 16 formed on the lower surface of the head is pushed into the rising portion 7 formed on the seat support portion 2.
Next, the backrest portion 13 is pushed downward while fitting the groove 17 into the backrest support portion 3, and its lower surface is brought into contact with the rear surface of the seat portion 12.
上記のように構成されたソファーは、支持体１の台座３にクッション体１１の座部裏面の凹部１４が密に嵌合しており、かつ支持体１の立ち上がり部７に座部裏面の細溝１６が密に嵌合しており、加えて支持体１の背もたれ支持部３に背もたれ部１３が密に嵌合しているので、全体が強く結合して一体化され、一度組み立てた後には容易に分解することがない。 In the sofa configured as described above, the recess 14 on the back surface of the cushion body 11 is closely fitted to the pedestal 3 of the support body 1, and the back surface of the seat 1 is narrowly fitted to the rising portion 7 of the support body 1. Since the groove 16 is closely fitted, and the backrest 13 is tightly fitted to the backrest support 3 of the support 1, the whole is strongly coupled and integrated. It does not decompose easily.
上記においては一人用のソファーとして構成したが、支持体１を複数並列させ、クッション体１１を複数人用の大きさのものとすることにより、二人がけないし数人がけ用のソファーとすることができる。 In the above, it is configured as a sofa for one person, but by arranging a plurality of supports 1 and a cushion body 11 having a size for a plurality of persons, a sofa for two persons or several persons can be formed. Can do.
この発明は、座部支持部と背もたれ支持部とを一体化してあるので、背もたれ支持部が安定する。したがって、クッション体の背もたれの変形を未然に防止することができる。そして、支持体にクッション体を嵌め込むだけで組立が完了するので、組み立て作業は極めて容易なものであり、産業上の利用可能性を有するものである。 In the present invention, since the seat support part and the back support part are integrated, the back support part is stabilized. Therefore, deformation of the backrest of the cushion body can be prevented in advance. And since an assembly is completed only by fitting a cushion body in a support body, an assembly operation is very easy and has industrial applicability.
