Description
本発明は、腰掛け構造物のリクライニング機構の改良、詳しくは、リクライニング時における背凭れの後方への飛び出しを抑えることができ、また、着座者の衣服のずり上がりも防止でき、しかも、複数人掛けのソファにも採用できる腰掛け構造物のリクライニング機構に関するものである。 The present invention is an improvement of a reclining mechanism for a stool structure, and more specifically, can prevent the backrest from jumping out backward during reclining, and can prevent a seated person's clothes from rising, and moreover The present invention relates to a reclining mechanism of a stool structure that can also be used for a sofa.
近年、一般住宅やマンションの居住者が、部屋でくつろぐためにリクライニングソファを使用することが多くなっている。そして、部屋にリクライニングソファを配置する際には、倒した背凭れが壁とぶつからないようにソファを壁から離して配置することが多い。 In recent years, occupants of ordinary houses and condominiums use reclining sofas to relax in a room. When a reclining sofa is arranged in a room, the sofa is often arranged away from the wall so that a fallen backrest does not collide with the wall.
しかしながら、上記のようにソファを壁から離して配置すると、背凭れを起こした状態においてソファと壁の隙間がデッドスペースとなるため、ソファ前方のスペースが狭められてしまい、ソファに座った際、部屋が狭苦しい印象となり易い。 However, if the sofa is placed away from the wall as described above, the space between the sofa and the wall becomes a dead space in the state where the back is raised, so the space in front of the sofa is narrowed, and when sitting on the sofa, The room tends to be a narrow impression.
そこで、従来においては、リクライニング時における背凭れの後方への移動をできるだけ抑えてソファを壁際に配置できるように、背凭れの傾倒にしたがって座部を前方に移動させる技術が提案されている(例えば、特許文献１〜３参照)、 Therefore, conventionally, a technique has been proposed in which the seat is moved forward according to the inclination of the backrest so that the backrest of the backrest at the time of reclining can be suppressed as much as possible so that the sofa can be disposed on the wall (for example, , See Patent Documents 1 to 3),
しかしながら、上記従来の座部の移動のみに頼った構造では、座部の前後方向の移動幅が非常に大きくなってしまうため、ソファの前にテーブル等の家具を配置することが難しくなるなど、使用上において多くの不満があった。 However, in the structure that relies only on the movement of the conventional seat, the movement width in the front-rear direction of the seat becomes very large, and it becomes difficult to arrange furniture such as a table in front of the sofa. There were many complaints in use.
一方、リクライニングソファ全般の課題としては、リクライニング時に背凭れ面と座面の相対的な位置関係が変わる(例えば図１０では、背凭れを倒すにしたがって背凭れ面が座面から離れてしまう)ことで、上着がずり上がってしまい着座者が不快な思いをする問題がある。 On the other hand, as a general problem of the reclining sofa, the relative positional relationship between the backrest surface and the seat surface changes during reclining (for example, in FIG. 10, the backrest surface moves away from the seat surface as the backrest is tilted). Therefore, there is a problem that the occupant feels uncomfortable because the outerwear rises.
また、この問題は、文献１に開示されたソファのように、背凭れの回動支点をクッションの表側に移動させることで解決できるものの、この構造を複数人掛けのソファに採用すると、座席の境目に連結部分が突き出た状態となるため、複数の座席を跨いで座ったり横になったりすることができない。 Although this problem can be solved by moving the pivot point of the backrest to the front side of the cushion, as in the sofa disclosed in Document 1, if this structure is adopted for a sofa with multiple seats, Since the connecting portion protrudes at the boundary, it is impossible to sit or lie across a plurality of seats.
そこで本発明は、上記問題を鑑みてなされたものであり、その目的とするところは、リクライニング時における背凭れの後方への移動を抑制してソファなどの腰掛けを壁際に設置することができ、さらに、着座者の上着のずり上がりも防止可能で、しかも、座席ごとにリクライニングを行う複数人掛けのソファにも適用できるソファのリクライニング機構を提供することにある。 Therefore, the present invention has been made in view of the above problems, and the object of the present invention is to suppress the back movement of the backrest during reclining and to install a stool such as a sofa near the wall, It is another object of the present invention to provide a sofa reclining mechanism that can prevent a seated occupant from climbing and that can be applied to a multi-seat sofa that reclines for each seat.
本発明者が上記課題を解決するために採用した手段を添付図面を参照して説明すれば次のとおりである。 Means employed by the present inventor for solving the above-described problems will be described with reference to the accompanying drawings.

前記座クッションＣ 2 を背凭れ枠１に固定することなく座枠２のみに固定し、更に背凭れ枠１と座枠２を、背凭れ枠１の本体部11を起立させた状態で座枠２の側方に背凭れ枠１の突出し部12が隣接並行するように両者を連結したことにより、
前記突出し部12の長さ分だけ背凭れ枠の回動支点Ｐを座枠２の前側にずらして、傾倒時における背凭れ頂部の後方への移動を抑制可能とした点に特徴がある。
That is, the present invention, the reclining mechanism, the lower side of the main body portion 11 of the back cushion C 1 is disposed, the backrest frame 1 projecting portions 12, 12 which are bent forwardly is provided on both sides; A seat frame 2 in which a seat cushion C 2 can be disposed on the upper side, and the projecting end portions 12 a of the backrest frame 12 are rotatably connected to both sides; While including a base 3 that is installed so as to be able to advance and retreat and is provided with a support portion 32 for supporting the backrest frame 1 on the rear side,
The seat frame in a state only fixed seat frame 2, which further backrest frame 1 and the seat frame 2, is raised to the body portion 11 of the backrest frame 1 without fixing the seat cushion C 2 to the backrest frame 1 By connecting the two so that the protruding part 12 of the backrest frame 1 is adjacent and parallel to the side of 2,
The feature is that the pivot point P of the backrest frame is shifted to the front side of the seat frame 2 by the length of the protruding portion 12 so that the backward movement of the backrest top portion during tilting can be suppressed.
また本発明は、上記背凭れ枠１の本体部11の上側にショルダーサポート13、若しくはヘッドレストを前後方向に回動自在に設けることにより、背凭れを倒した際、ショルダーサポート13またはヘッドレストを前方に傾けて背凭れ頂部の後方への飛び出しを抑制することもできる。 Further, the present invention provides a shoulder support 13 or a headrest that can be pivoted in the front-rear direction on the upper side of the main body 11 of the backrest frame 1 so that the shoulder support 13 or the headrest can be moved forward when the backrest is tilted. It can also be tilted to suppress the rearward jumping out of the top of the backrest.
そしてまた、本発明においては、上記基台３の支持部32を、基台３両側の側板間を架け渡したバー部材32aと、このバー部材32aに揺動自在に取り付けたスリット付きのスライドガイド32bとから構成し、更に背凭れ枠１の背面に固定した取付け金具14を前記スライドガイド32bのスリットに装着して、背凭れ枠１を支持部32に上下スライド可能に取り付けることもできる。 In the present invention, the support portion 32 of the base 3 is provided with a bar member 32a that spans between the side plates on both sides of the base 3, and a slide guide with a slit that is swingably attached to the bar member 32a. It is also possible to attach the backrest frame 1 to the support portion 32 so as to be vertically slidable by attaching a mounting bracket 14 constituted by 32b and fixed to the back surface of the backrest frame 1 to the slit of the slide guide 32b.
また本発明は、上記リクライニング機構の構成に代えて、背クッションＣ1が配設される本体部11の上下中間位置の後側に、下方に所要角度で突出したステー部15・15が両サイドに設けられた背凭れ枠１と；上側に座クッションＣ2が配設可能である座枠２と；この座枠２が前後に進退可能に装着されるスライド部を備え、かつ、後側に背凭れ枠11の上下中央寄りの部位を支えるための支持部32が設けられた基台３と；固定端側に基台３の枢支部34が連結され、遊端側に背凭れ枠１のステー端部15aが枢支部34よりも低い位置で回転自在に連結されると共に、背凭れ枠１のステー端部15aの連結位置よりも基台３の枢支部34の連結位置に近く、かつ、前記ステー端部15aの連結位置よりも前側の位置に座枠２の後端部21が連結された揺動リンク５とを含んで構成し、
前記背凭れ枠１の傾倒時における基台３の枢支部34を支点Ｒとした揺動リンク５の下回り方向への回転により、背凭れ枠１の回動支点Ｐ’を座枠２の後端Ｑ’よりも大きく前方に移動せしめて、背凭れ頂部の後方への移動を抑制することもできる。
Further, in the present invention, instead of the above reclining mechanism, stay portions 15 and 15 projecting downward at a required angle are provided on both sides on the rear side of the upper and lower intermediate positions of the main body portion 11 where the back cushion C 1 is disposed. A back frame 1 provided on the seat; a seat frame 2 on which the seat cushion C 2 can be disposed; and a slide portion on which the seat frame 2 is mounted so as to be able to move forward and backward, and on the rear side. A base 3 provided with a support portion 32 for supporting a portion near the center of the backrest frame 11; a pivot portion 34 of the base 3 is connected to the fixed end side, and the backrest frame 1 is connected to the free end side. The stay end 15a is rotatably connected at a position lower than the pivot support 34, is closer to the connection position of the pivot support 34 of the base 3 than the connection position of the stay end 15a of the backrest frame 1, and And a swing link 5 in which the rear end portion 21 of the seat frame 2 is connected to a position in front of the connecting position of the stay end portion 15a. Configure
When the backrest frame 1 is tilted, the pivoting support point P ′ of the backrest frame 1 is set to the rear end of the seat frame 2 by the downward rotation of the swing link 5 with the pivotal support 34 of the base 3 as the fulcrum R. It is also possible to suppress the movement of the backrest to the rear by moving it forward larger than Q ′.
本発明では、座枠に対する背凭れ枠の連結部位を前方に屈曲させたことにより、背凭れの回動支点を前側に移動させることができるため、リクライニング時に背凭れを下方に沈みこませながら傾倒させることが可能となり、それによって背凭れの後方への移動を抑制することができる。 In the present invention, the connecting portion of the back frame with respect to the seat frame is bent forward, so that the pivot point of the backrest can be moved to the front side, so that the backrest is tilted while sinking downward during reclining. This makes it possible to suppress the back movement of the backrest.
一方、背凭れ枠の下端と座枠の後端、基台の枢支部を所定の位置・間隔で揺動リンクによって連結した場合においても、背凭れの回動支点を座部後端よりも大きく前方に移動させることができるため、上記と同様の効果を得ることができる。 On the other hand, even when the lower end of the backrest frame, the rear end of the seat frame, and the pivotal support portion of the base are connected by a swing link at a predetermined position and interval, the pivot point of the backrest is larger than the rear end of the seat portion. Since it can be moved forward, the same effect as described above can be obtained.
また、上記構造を利用して背凭れの後方への移動を抑制すれば、同じ抑制手段として併用する座部の前後移動を小さく抑えることもできるため、ソファ前方にテーブル等の家具を配置し易くなる効果も得られる。 In addition, if the back movement of the backrest is suppressed using the above structure, it is possible to suppress the back-and-forth movement of the seat used together as the same suppression means, so it is easy to place furniture such as a table in front of the sofa The effect becomes.
そしてまた、上記のように背凭れの回動支点を背クッションの前側に移動させることによって、リクライニング時における座クッションと背クッションの相対的な位置ズレも抑制できるため、上着のずり上がり防止にも一定の効果を奏する。 Also, by moving the pivot point of the backrest to the front side of the back cushion as described above, the relative displacement between the seat cushion and the back cushion at the time of reclining can be suppressed, thus preventing the upper cover from rising. Also has a certain effect.
他方また、上記背凭れ枠と座枠の連結は、枠体がクッション上に表れないように行っているため、本発明に係る技術を複数人掛けのソファに採用した場合でも、座り心地に影響はなく、座席間を跨いでの着座や横臥を問題なく行うことができる。 On the other hand, since the back frame and the seat frame are connected so that the frame body does not appear on the cushion, even when the technique according to the present invention is applied to a sofa for a plurality of persons, it affects the sitting comfort. No, you can sit and lie down between the seats without problems.
したがって、本発明により、リクライニングソファを壁際に配置することができ、しかも、ソファの座り心地も改善できる腰掛け構造物のリクライニング機構を提供できることから、本発明の実用的利用価値は頗る高い。 Therefore, according to the present invention, the reclining sofa can be disposed on the wall, and the reclining mechanism of the seat structure that can improve the sitting comfort of the sofa can be provided. Therefore, the practical utility value of the present invention is very high.

本発明の実施例１について、図１から図５に基いて説明する。同図において、符号１で指示するものは背凭れ枠であり、符号２で指示するものは座枠である。また、符号３で指示するものは基台であり、符号４で指示するものは、スプリング(引きバネ)である。
“Example 1”
A first embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a backrest frame, and what is indicated by reference numeral 2 is a seat frame. Also, what is indicated by reference numeral 3 is a base, and what is indicated by reference numeral 4 is a spring (pull spring).
この実施例１では、背クッションＣ1が固定される本体部11の下側に、前方に屈曲した突出し部12・12が両サイドに設けられた背凭れ枠１に、背クッションＣ1を取り付けてリクライニングソファＳの背凭れを形成している(図１参照)。 In Example 1, the lower side of the main body portion 11 of the back cushion C 1 is fixed to the backrest frame 1 projecting portions 12, 12 which are bent forwardly is provided on both sides, attaching the back cushion C 1 This forms the backrest of the reclining sofa S (see FIG. 1).
また、上記背凭れの背凭れ枠１については、図２(a)に示すように本体部11を形成する金属パイプの下部を屈曲して突出し部12・12を設けている(図２参照)。そして、上記背凭れ枠１の本体部11の上側には、ショルダーサポート13を前後方向に回動自在に連結している。 Further, the backrest frame 1 of the backrest is provided with protruding portions 12 and 12 by bending the lower part of the metal pipe forming the main body portion 11 as shown in FIG. 2 (a) (see FIG. 2). . And the shoulder support 13 is connected with the upper side of the main-body part 11 of the said backrest frame 1 so that rotation in the front-back direction is possible.
一方、リクライニングソファＳの座部については、座枠２の上側に座クッションＣ2を取り付けて形成している。そして、座枠２と背凭れ枠１は、背凭れ枠１の突端部12aを座枠２の中域部に回動自在に連結している。 On the other hand, the seat portion of the reclining sofa S is formed by attaching a seat cushion C 2 on the upper side of the seat frame 2. And the seat frame 2 and the backrest frame 1 have connected the protrusion part 12a of the backrest frame 1 to the middle area part of the seat frame 2 so that rotation is possible.
また、上記背凭れ枠１と座枠２の連結は、背凭れ枠１を起立させた状態で突出し部12が座枠２の側方に隣接並行するように行っている。そしてまた、背クッションＣ1と座クッションＣ2の形状も、背凭れ枠１を傾倒させた際、背クッションＣ1の下部と座クッションＣ2の後部が干渉しないように設計してある。 The backrest frame 1 and the seat frame 2 are connected such that the protruding portion 12 is adjacent and parallel to the side of the seat frame 2 in a state where the backrest frame 1 is raised. The shapes of the back cushion C 1 and the seat cushion C 2 are also designed so that the lower part of the back cushion C 1 and the rear part of the seat cushion C 2 do not interfere when the backrest frame 1 is tilted.
一方、上記背凭れと座部は、リクライニングソファＳの基台３上に配設している。具体的には、図２(b)に示すように基台３の側板内側に設けたスライド部31・31に対し、座枠２を前後に進退可能に装着している。また、基台３の後部に設けた支持部32には背凭れ枠１を取り付けている。 On the other hand, the backrest and the seat are disposed on the base 3 of the reclining sofa S. Specifically, as shown in FIG. 2 (b), the seat frame 2 is attached to slide portions 31 and 31 provided inside the side plate of the base 3 so as to be able to move forward and backward. A backrest frame 1 is attached to a support portion 32 provided at the rear portion of the base 3.
ちなみに実施例１では、上記基台３の支持部32を、基台３両側の側板を架け渡したバー部材32aと、このバー部材32aに揺動自在に取り付けたスリット付きのスライドガイド32bとから構成すると共に、スライドガイド32bのスリットに背凭れ枠１の裏側に固定したコ字状の取付け金具14を装着して、背凭れ枠１を支持部32に上下スライド可能に取り付けている(図３参照)。 Incidentally, in the first embodiment, the support portion 32 of the base 3 is composed of a bar member 32a that spans side plates on both sides of the base 3, and a slide guide 32b with a slit that is swingably attached to the bar member 32a. In addition, a U-shaped mounting bracket 14 fixed to the back side of the backrest frame 1 is attached to the slit of the slide guide 32b, and the backrest frame 1 is slidably attached to the support portion 32 (FIG. 3). reference).
そして、リクライニングソファＳを上記のように構成したことにより、背凭れ枠１の突出し部12の分だけ、背凭れ部１の回動支点Ｐを座枠２の前側にずらすことができるため、図４に示すように座枠２の後端部Ｑを支点とする場合よりも、背凭れ傾倒時における背凭れ頂部の後方への移動を抑制することができる。 Since the reclining sofa S is configured as described above, the pivot point P of the backrest 1 can be shifted to the front side of the seat frame 2 by the protruding portion 12 of the backrest 1. As shown in FIG. 4, the rearward movement of the backrest top portion when the backrest is tilted can be suppressed as compared with the case where the rear end portion Q of the seat frame 2 is a fulcrum.
また、上記効果によって、図５(a)に示すように背凭れの飛び出し抑制手段として併用する座枠２の前後移動も小さく抑えることもできる。また更に、背凭れのショルダーサポート13を前方に起こせば、図５(b)に示すように、背凭れの後方への移動を一層小さくすることができる。 Further, as a result of the above effect, as shown in FIG. 5 (a), the back-and-forth movement of the seat frame 2 that is used together as a back-out jumping-inhibiting means can also be suppressed. Furthermore, if the shoulder support 13 of the backrest is raised forward, the backward movement of the backrest can be further reduced as shown in FIG. 5 (b).
そしてまた、この実施例１では、座枠２の後端部21と基台３の後壁部33とをスプリング４で連結しているため、上半身の体重を後方にかけて背凭れを傾した後、上半身を軽く起こせばスプリング４の付勢力によって背凭れ部１を簡単に起こすことができる。 In the first embodiment, since the rear end portion 21 of the seat frame 2 and the rear wall portion 33 of the base 3 are connected by the spring 4, the upper body weight is applied to the rear and the backrest is inclined. If the upper body is raised slightly, the backrest 1 can be easily raised by the urging force of the spring 4.
『実施例２』
次に実施例２について図６〜図８に基いて以下に説明する。なお同図において、符号５で指示するものは、揺動リンクである。この実施例２では、背凭れ枠１の本体部11の後側に所定角度で突き出したロッド状のステー部15・15を両サイドに設けている(図６、図７参照)。また基台３の側板には、揺動リンク５を連結するための枢支部34・34を設けている。
“Example 2”
Next, Example 2 will be described below with reference to FIGS. In the figure, what is indicated by reference numeral 5 is a swing link. In the second embodiment, rod-like stay portions 15 and 15 projecting at a predetermined angle on the back side of the main body portion 11 of the backrest frame 1 are provided on both sides (see FIGS. 6 and 7). Further, the side plates of the base 3 are provided with pivot portions 34 and 34 for connecting the swing link 5.
そして、上記背凭れ枠１のステー端部15aと、座枠２の後端部21、基台３の枢支部32は板状の揺動リンク５によって連結している。具体的には、揺動リンク５の固定端側に基台３の枢支部34を連結し、遊端側に背凭れ枠１のステー端部15aを連結する一方、背凭れ枠１のステー端部15aの連結位置よりも基台３の枢支部34の連結位置に近く、かつ、前記ステー端部15aの連結位置よりも前側の位置に座枠２の後端部21を連結している。 The stay end 15 a of the back frame 1, the rear end 21 of the seat frame 2, and the pivotal support 32 of the base 3 are connected by a plate-like swing link 5. Specifically, the pivot portion 34 of the base 3 is connected to the fixed end side of the swing link 5 and the stay end portion 15a of the backrest frame 1 is connected to the free end side, while the stay end of the backrest frame 1 is connected. The rear end portion 21 of the seat frame 2 is connected to a position closer to the connection position of the pivot portion 34 of the base 3 than the connection position of the portion 15a and to the front side of the connection position of the stay end portion 15a.
ちなみに実施例２では、上記揺動リンク５に形状が緩いＶ字状の金属板を使用し、Ｖ字の両端部に基台３の枢支部34と背凭れ枠１のステー端部15aを連結し、頂点部に座枠２の後端部21を連結している。また、座枠２の後端部の形状は上向きに屈曲した形状としている。 Incidentally, in the second embodiment, a loosely V-shaped metal plate is used for the swing link 5, and the pivotal support 34 of the base 3 and the stay end 15 a of the backrest frame 1 are connected to both ends of the V-shape. The rear end 21 of the seat frame 2 is connected to the apex. Further, the shape of the rear end portion of the seat frame 2 is a shape bent upward.
なお、揺動リンク５の三つの連結点については、クッション部材の相対的な位置関係が殆ど変わらない最適なレバー比によって各連結点の位置を決定しており、またこの連結点の位置に応じて揺動リンク５の形状や座枠２の後端部21の形状を設計している。また、基台３には、座枠２が前後に進退可能に装着されるスライド部を備えると共に、後側に背凭れ枠11の上下中央寄りの部位を支えるための支持部32を設けている。 In addition, about the three connection points of the rocking | fluctuation link 5, the position of each connection point is determined by the optimal lever ratio with which the relative positional relationship of a cushion member does not change almost, and according to the position of this connection point Thus, the shape of the swing link 5 and the shape of the rear end portion 21 of the seat frame 2 are designed. In addition, the base 3 includes a slide portion on which the seat frame 2 is mounted so that the seat frame 2 can be moved back and forth, and a support portion 32 for supporting a portion near the vertical center of the backrest frame 11 is provided on the rear side. .
そして、上記のようにリクライニングソファＳを構成したことにより、図８に示すように、背凭れ枠１の傾倒に伴う基台３の枢支部34を支点Ｒとした揺動リンク５の回転によって、背凭れ枠１の回動支点Ｐ’を座枠の後端Ｑ’よりも大きく前方に移動させることができるため、傾倒時における背凭れ部１の後方への移動を抑制することが可能となる。 Then, by configuring the reclining sofa S as described above, as shown in FIG. 8, by the rotation of the swing link 5 with the pivotal support portion 34 of the base 3 accompanying the tilt of the backrest frame 1 as the fulcrum R, Since the pivot fulcrum P ′ of the backrest frame 1 can be moved forward more greatly than the rear end Q ′ of the seat frame, it is possible to suppress the rearward movement of the backrest portion 1 when tilting. .
本発明は、概ね上記のように構成されるが、本発明は図示の実施形態に限定されるものではなく、「特許請求の範囲」の記載内において種々の変更が可能であって、例えば、実施例１における背凭れ枠１の突出し部12の長さは、座枠２の長さの範囲で自由に変更することができる。 The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of “Claims”. The length of the protruding portion 12 of the backrest frame 1 in the first embodiment can be freely changed within the range of the length of the seat frame 2.
但し、背凭れ枠１の突出し部12を長くすると、背凭れ頂部の飛び出し抑制効果は高まるが、背凭れ枠１の落ち込み量も同時に大きくなるため、背凭れ枠１の屈曲部位が床にぶつからないように長さを調整する必要がある。 However, if the protruding portion 12 of the backrest frame 1 is lengthened, the effect of suppressing the protrusion of the backrest top portion is enhanced. However, since the amount of the backrest frame 1 is also increased, the bent portion of the backrest frame 1 does not hit the floor. It is necessary to adjust the length.
また、実施例２における揺動リンク５の形状に関しても、Ｖ字型でなくＴ字型や三角型等の形状としてもよく、また座枠２の後端部21の形状に関しても、上向きに持出し部を設けた形状であってもよい(図９参照)。 Further, the shape of the swing link 5 in the second embodiment may be a T shape or a triangular shape instead of the V shape, and the shape of the rear end portion 21 of the seat frame 2 is taken upward. The shape may be provided with a portion (see FIG. 9).
そしてまた、背凭れのショルダーサポート13は、前後に角度調節が可能なヘッドレストであってもよく、また本発明に係るリクライニング機構は、電動アクチュエータ等を用いて電動化することもでき、何れのものも本発明の技術的範囲に属する。 Further, the backrest shoulder support 13 may be a headrest capable of adjusting the angle in the front-rear direction, and the reclining mechanism according to the present invention may be electrified using an electric actuator or the like. Are also within the technical scope of the present invention.
近年、個人や一般家庭においてもリクライニングソファの需要は大きくなっており、特に一般住宅やマンションでは部屋の間取りに充分な余裕がないことも多いため、できるだけ室内空間を有効に利用できるソファが望まれている。 In recent years, the demand for reclining sofas has increased in individuals and general households. Especially, in general houses and condominiums, there is often no room for room layout, so a sofa that can effectively use indoor space as much as possible is desired. ing.
そのような中で、本発明の腰掛け構造物のリクライニング機構は、ソファ等の腰掛け具を壁際に配置可能とすることで背凭れ起立時においてソファ前方の空間を広くとることができ、また複数人が腰掛けるロングソファにも適用できる有用な技術であるため、その産業上の利用価値は非常に高い。 Under such circumstances, the reclining mechanism of the stool structure of the present invention allows a space in front of the sofa to be widened when standing on the back by allowing a stool such as a sofa to be arranged on the wall, and also allows multiple people Because it is a useful technology that can be applied to long sofas, the industrial utility value is very high.
