Description

本発明は、ソファーに係わり、更に詳しくは使用シーンに応じて形態を変化させるソファーに関するものである。 The present invention relates to a sofa, and more particularly to a sofa that changes its form in accordance with a use scene.

従来から応接間や待合室、ロビーといった場所に、それぞれ最適な形態のソファーが設置されている。また、使用シーンに応じて形態を変化させることが可能なソファーも各種提供されている。 Traditionally, sofas with optimal forms have been installed in places such as reception rooms, waiting rooms, and lobbies. There are also various sofas that can change their form according to the scene of use.

例えば、特許文献１には、座部を前後スライド移動可能とし、座部の後部を背凭れ部の下方に設けた収容空間に侵入させて、座部の奥行幅を変更できるソファーが開示されている。このソファーは、座部の後部を背凭れ部下方に押し込んだ通常の使用状態では、座部が極端に前方へ突出することがないので、通常の着座姿勢をとることができ、また座部を引き出せば奥行幅が広くなるので、座部の上で胡座をかいたり、横になったりする姿勢を余裕でとることができる。また、横方向に長い背凭れ部を有するとともに、座部を左右に分割し、分割座部をそれぞれ前後スライド移動できる構造としたソファーも開示されている。 For example, Patent Document 1 discloses a sofa that can change the depth of the seat by allowing the seat to slide back and forth and allowing the rear portion of the seat to enter a housing space provided below the backrest. Yes. In the normal use state where the rear part of the seat part is pushed below the backrest part, the sofa does not protrude extremely forward, so that the normal sitting posture can be taken. If you pull it out, the depth is widened, so you can take the posture of sitting on the seat or lying down. There is also disclosed a sofa having a backrest portion that is long in the lateral direction, a structure in which the seat portion is divided into left and right portions, and each of the divided seat portions can be slid back and forth.

また、特許文献２には、背凭れ部と座部を左右に分割し、それぞれ背凭れ部と座部が連動して姿勢を変化させることが可能なソファーが開示されている。つまり、背凭れ部の前後傾動動作に連動して座部が前後移動する構造のソファーであり、左右に座る使用者の好みに応じて背凭れ部と座部の姿勢を変化させることができるのである。 Patent Document 2 discloses a sofa in which a backrest part and a seat part are divided into left and right parts, and the backrest part and the seat part can change the posture in conjunction with each other. In other words, it is a sofa with a structure that the seat moves back and forth in conjunction with the back and forth tilting movement of the backrest, and the posture of the backrest and seat can be changed according to the preference of the user sitting left and right is there.

しかし、何れのソファーも大人と子供のように使用者の体格差が大きく異なる場合、あるいは妊婦や高齢者のように深く座ると立ち上がるのに苦労する場合、大人と子供が並んで座る場合などのように、使用シーンに応じて形態を変化させるものではない。 However, if the sofas have a large difference in physique between adults and children, or if you are struggling to get up when sitting deeply like a pregnant woman or an elderly person, adults and children sit side by side Thus, the form is not changed according to the use scene.

また、待合室やロビー等のように多数の利用者がいる場所には、三人掛けの横幅を有するソファーを設置している場合が多い。しかし、人間の行動心理的に他人と接近して並んで座ることに抵抗感があるため、通常はソファーの両端に座って二人掛けとなることが多い。また、知り合い同士の二人が座る場合には、ソファーの一側に寄って並んで座り、反対側は空いていることが通常である。そして、一人分だけ空いているファーに後で座るには抵抗感がある。また、体格が通常よりも大きな使用者が一人座ると、物理的にあと二人座ることは不可能である。このように、三人掛けのソファーであっても事実上、二人掛けのソファーになっていることが殆どである。これではスペースの有効利用が図れない。 In many places where there are a large number of users such as waiting rooms and lobbies, a sofa having a three-seat width is installed. However, because there is a sense of resistance to sitting side by side with other people in terms of human behavioral psychology, usually sitting on both ends of the sofa often takes two people. In addition, when two people of acquaintances sit down, they usually sit side by side on the sofa and the other side is vacant. And I feel reluctant to sit down on a fur that's free for one person later. Also, if one user with a larger physique sits normally, it is impossible to physically sit two more. As described above, even a three-seat sofa is practically a two-seat sofa. This makes it impossible to use the space effectively.

次に、添付図面に示した実施形態に基づき、本発明を更に詳細に説明する。図１及び図２は本発明に係るソファーを示し、図３及び図４は本発明のソファーの代表的な実施形態を示し、図５及び図６は１単位ソファーを示し、図７及び図８は１．５単位ソファーを示し、図中符号Ａは１単位ソファー、Ｂは１．５単位ソファー、１は脚部、２は座部、３は背凭れ部、４は袖部をそれぞれ示している。 Next, the present invention will be described in more detail based on the embodiments shown in the accompanying drawings. 1 and 2 show a sofa according to the present invention, FIGS. 3 and 4 show a typical embodiment of the sofa of the present invention, FIGS. 5 and 6 show a one-unit sofa, and FIGS. Indicates a 1.5 unit sofa, in which A is a 1 unit sofa, B is a 1.5 unit sofa, 1 is a leg, 2 is a seat, 3 is a backrest, and 4 is a sleeve. Yes.

本発明のソファーは、図１に示すように、脚部１に固定した座部２の後部上位に、背凭れ部３を偏心位置で前後回動可能に設けるとともに、該背凭れ部３を立起させた第１姿勢と、該背凭れ部３を前側に倒した第２姿勢をとることが可能であり、第１姿勢では座部２の実効奥行幅が広く、第２姿勢では座部２の実効奥行幅が狭く且つ背凭れ部３の上部が略水平な載置面となるものであり、前記座部２の後部と背凭れ部３の下端との間に、該背凭れ部３の姿勢に依らず常に一定の空間Ｓを有してなるものである。図１において、前記背凭れ部３の第１姿勢を実線で、第２姿勢を想像線で示している。 As shown in FIG. 1, the sofa of the present invention is provided with a backrest portion 3 that can be pivoted back and forth in an eccentric position above the rear portion of the seat portion 2 fixed to the leg portion 1, and the backrest portion 3 is raised. The raised first posture and the second posture in which the backrest portion 3 is tilted forward can be taken, and the effective depth of the seat portion 2 is wide in the first posture, and the seat portion 2 in the second posture. The effective depth width of the backrest portion 3 is narrow and the upper portion of the backrest portion 3 is a substantially horizontal mounting surface, and between the rear portion of the seat portion 2 and the lower end of the backrest portion 3, It always has a constant space S regardless of the posture. In FIG. 1, the first posture of the backrest 3 is indicated by a solid line, and the second posture is indicated by an imaginary line.

本発明に係るソファーは、座部２の両側前部を脚部１を構成する前脚杆１Ａ，１Ａで支持するとともに、両側後部を後脚杆１Ｂ，１Ｂで支持し、前記後脚杆１Ｂ，１Ｂの上部は前記座部２の座面より上方へ延びて支持杆５となり、該支持杆５の上端部に受け部材６を固定し、両側の受け部材６，６で背凭れ部３の両側が偏心位置で回動可能に支持されている。また、座部２の側部に袖部４を設けた場合には、前記受け部材６は該袖部４の後部が受け部６Ａとなってその機能を有する。この場合、前記支持杆５の上端部に肘掛け機能を有する袖部４の後部が固定されている。 The sofa according to the present invention supports both front portions of the seat portion 2 with front leg rods 1A and 1A constituting the leg portion 1, and supports both rear portions with rear leg rods 1B and 1B. The upper portion of 1B extends upward from the seating surface of the seat portion 2 to become a support rod 5, and a receiving member 6 is fixed to the upper end portion of the support rod 5, and both sides of the backrest portion 3 are fixed by the receiving members 6 and 6 on both sides. Is supported rotatably at an eccentric position. Moreover, when the sleeve part 4 is provided in the side part of the seat part 2, the rear part of this sleeve part 4 serves as the receiving part 6A, and has the function. In this case, the rear portion of the sleeve portion 4 having an armrest function is fixed to the upper end portion of the support rod 5.

図１中、Ｐは前記背凭れ部３の回転中心を示している。前記背凭れ部３は、側面視において略長方形状であり、その一側部を回転中心Ｐとして前後方向の回動するようになっている。図１の実線は背凭れ部３の第１姿勢を示し、この姿勢で背凭れ部３は回転中心Ｐより上方へ延びやや後傾した形状となっている。図中符号７は第１姿勢における背凭れ面であり、符号８は第１姿勢では上面部となるが第２姿勢における背凭れ面であり、後面側の符号９は第２姿勢では上面となる略水平な載置面である。ここで、第１姿勢の前記背凭れ部３における背凭れ面７と第２姿勢の前記背凭れ部３における背凭れ面８がそれぞれ同じ角度で若干後傾姿勢にされ、着座時に背中や腰部を安定に支持できるようにしている。 In FIG. 1, P indicates the rotation center of the backrest 3. The backrest 3 has a substantially rectangular shape in a side view, and rotates in the front-rear direction with the one side as a rotation center P. A solid line in FIG. 1 shows a first posture of the backrest portion 3, and in this posture, the backrest portion 3 extends upward from the rotation center P and has a slightly inclined shape. In the figure, reference numeral 7 is a backrest surface in the first posture, reference numeral 8 is an upper surface portion in the first posture, but a backrest surface in the second posture, and reference symbol 9 on the rear surface side is an upper surface in the second posture. It is a substantially horizontal mounting surface. Here, the backrest surface 7 in the backrest portion 3 in the first posture and the backrest surface 8 in the backrest portion 3 in the second posture are each slightly tilted backward at the same angle, and the back and waist are seated when sitting. We are trying to support it stably.

前記背凭れ部３を偏心位置で前後回動可能に設けるとは、図１において回転中心Ｐから背凭れ面７までの距離より、背凭れ面８までの距離が長いことを意味している。つまり、前記背凭れ部３が第１姿勢のときの背凭れ面７より、第２姿勢のときの背凭れ面８の位置が、回転中心Ｐを基準としてより前方にせり出すのである。それにより、前記背凭れ部３が第１姿勢では座部２の実効奥行幅が広く、第２姿勢では座部２の実効奥行幅が狭くなるのである。また、前記座部２の後部と背凭れ部３の下端との間に、該背凭れ部３の姿勢に依らず常に一定の空間Ｓを有しているので、図２に示すように、前記背凭れ部３が第２姿勢をとったときにも、座面から十分に高い位置で着座者を支持でき、体格の大きい着座者の腰部を支持することができ、また体格の小さい着座者の背中を支持することができるのである。尚、図２中の符号Ｈ１は妊婦、Ｈ２は子供を示している。 Providing the backrest portion 3 so as to be able to rotate back and forth at an eccentric position means that the distance from the rotation center P to the backrest surface 7 in FIG. That is, the position of the backrest surface 8 when the backrest portion 3 is in the second posture protrudes further forward with respect to the rotation center P than the backrest surface 7 when the backrest portion 3 is in the first posture. Thereby, when the backrest 3 is in the first posture, the effective depth width of the seat portion 2 is wide, and in the second posture, the effective depth width of the seat portion 2 is narrowed. Further, since a constant space S is always provided between the rear portion of the seat portion 2 and the lower end of the backrest portion 3 regardless of the posture of the backrest portion 3, as shown in FIG. Even when the backrest 3 takes the second posture, it can support the seated person at a sufficiently high position from the seating surface, can support the waist of the seated person with a large physique, and the seated person with a small physique You can support your back.
