産業上の利用分野
本考案は、座者が背部の局部的押圧を得ること
ができる椅子に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a chair that allows the sitter to obtain localized pressure on the back.
従来の技術及びその問題点
椅子への座者は、着座姿勢において背部、特に
背中の下部に適度な局部的押圧を受けることによ

ことが知られている。しかしながら、このような
快さは必要な時に一時的に求められる性質のもの
であり、座者は通常の着座状態においては、より
均等な圧力のものに背部を支持されることを望
む。したがつて、通常は座者の背部を比較的均等
な圧力をもつて支持でき、必要に応じて該背部を
局部的に押圧しうる椅子があれば便利である。PRIOR TECHNOLOGIES AND THEIR PROBLEMS A person sitting on a chair can feel physical comfort accompanied by acupressure effects by receiving moderate local pressure on the back, especially the lower part of the back, in a sitting position. Are known. However, such comfort is of a nature that is only temporarily sought when necessary, and in a normal sitting state, the seater desires to have his or her back supported by something with more even pressure. Therefore, it would be convenient to have a chair that can normally support the back of the sitter with relatively even pressure and that can press the back locally if necessary.
しかし、従来のこの種の椅子は、単に一方の面
の略上下全体に亘つて、指圧的効果を得るための
突部を設け、他方の面を通常の背もたれ面として
双方を使用し得るように回動可能に支持したもの
に過ぎなかつた。したがつて、突部のある面を使
用する場合、座者が後傾すると、背中の略全面に
突部による押圧を受けるのみで力が全体に分散
し、特に効果のある背中下部に集中した押圧を受
けることができなかつた。 However, conventional chairs of this type simply have protrusions covering almost the entire top and bottom of one surface to obtain an acupressure effect, and the other surface can be used as a normal backrest surface. It was nothing more than a rotatable support. Therefore, when using a surface with protrusions, when the seater leans back, almost the entire back is pressed by the protrusions, and the force is distributed throughout the body, concentrating on the lower back where it is particularly effective. I couldn't take pressure.

の作用線を第3図に矢印Aで示す。 1 and 2 show a base 1 having a seat 2 and legs 3, and a backrest 4 supported by the base 1.
It shows a reception chair with a Seat part 2
The legs 3 are constructed in the same manner as a normal reception chair. The backrest portion 4 includes a pair of backrest plate support portions 40 that are integrally formed with the leg portions 3 and extend upward from both left and right sides of the leg portions 3, and a support that extends horizontally from the top of the backrest plate support portions 40. a shaft 41;
A backrest plate 42 is rotatably supported between backrest plate support parts 40 by the support shaft 41. The backrest plate 42 has a core having an appropriate strength necessary to maintain a flat plate shape, and is covered with a cushioning member and an outer skin. This backrest plate 42
is supported by a support shaft 41 at a position offset from the center in the longitudinal direction of the side. Hereinafter, from the support shaft 41 to the backrest plate 4 in the backrest plate 42,
2. The longer distance to the upper and lower ends is called the long side, and the shorter side is called the short side. Due to such eccentric support, the backrest plate 42 has a surface located in front when the long side is at the bottom, which extends from the vicinity of the upper surface of the seat part 2 to the upper back of the sitter (slightly below the shoulders) as in a normal reception chair. The surface that lies forward when the short side is down is the lower back of the seater (slightly above the waist).
It extends from to near the shoulder. The edge, which becomes the front lower end when the short side is on the bottom, constitutes a pressing portion 44 that is adjusted to have an appropriate hardness by a combination of the rigidity of the core and the flexibility of the cushioning member. Furthermore, when the short side of the backrest plate 42 is at the bottom, the pressing portion 44 moves forward as the seater rotates around the support shaft 41 as the seater leans back, and presses against the lower back of the seater. ing. The line of action of this pressing force is indicated by arrow A in FIG.

囲内において適宜決められる。 Therefore, by holding the backrest plate 42 with the pins 43 with the long side facing down and using this chair, the sitter can obtain back support with relatively even pressure. If necessary, remove the pin 43 and rotate it so that the short side faces down, and use it in a rotatable state, as shown in FIG. It is possible to obtain physical pressure with the effect of acupressure. In particular, the edge of the short side of the backrest plate 42 constitutes a pressing portion 44 . Therefore, when the seater leans back with the short side facing down, the load due to the backward lean is applied to the long side, and the distance from the support shaft 41 to the load point becomes long and the distance to the pressing part becomes short. As a result, due to moment balance, a force larger than the load at the load point is obtained at the pressing portion. This results in
The seater can receive a strong pressing force concentrated on the lower part of the back, and can obtain great physical pleasure accompanied by an acupressure effect. In this way, in order to obtain intensive pressure from the pressing part 44 with the forward movement of the backrest plate 42, in a chair intended for an average adult, it is necessary to It is desirable that the distance be between 14 cm and 38 cm. If this distance is larger than 38 cm, it is difficult to obtain appropriate rotation of the backrest plate 42 as the seater leans back, and if this distance is smaller than 14cm, the forward distance of the pressing portion when the backrest plate is rotated becomes too small. When a seated person leans back from a seated position, the seater takes a backward posture and at the same time receives concentrated pressure on the lower back, thereby obtaining a particularly strong acupressure effect or physical pleasure. In order to obtain this effect, the distance from the upper surface of the seat to the lower end of the pressing part 44 when sitting is 8 cm.
15cm or less, preferably 10cm or more and 12cm or more
It is more desirable to set it to the following. The position of the upper end of the pressing portion is appropriately determined within the body range of the sitting person according to the desired pressing form.

逆の面を前方にして使用される。 Of course, the present invention can be applied to various chairs other than the above-mentioned reception chairs. In addition, the pressing part is formed by the edge of the backrest plate, and also by the part of the back of the seater.
Alternatively, various forms can be used in which two or more parts can be pressed intensively. FIG. 4 shows the pressing part 44A.
5 shows a chair in which two protrusions are formed on one side of the backrest plate 42, and FIG. 5 shows the backrest plate 42. In the drawings, parts and parts that are similar to the previous example are designated by the same numbers. This pressing portion 44A allows the sitting person to intensively press both sides of the spine in the lower back. Normally, this backrest plate 42 is used with the reverse side facing forward.

ものと同様である。 The position of the pressing portion 44A at this time is shown in FIG. 4 by a chain line. The heights of the lower end of the press and the support shaft from the seat are appropriately determined as necessary, but their desirable dimensions are the same as those described for the reception chair.

を提供することができる。Effects of the invention As is clear from the above, according to the invention, the surface of the backrest plate provided with the pressing portion and the surface that contacts the seater's back with relatively equal pressure can be selected by rotating around the support axis. The back of the seater can usually be supported with relatively even pressure, and if necessary, the back can be pressed locally, and the pressure is applied even when the seater is leaning backwards. It is possible to provide a chair that can exhibit an excellent effect that is extremely effective because the pressing part is moved forward as the pressing part moves forward.

きく得られる。 In particular, the backrest plate is supported by the support shaft such that the distance from the support shaft to the upper end of the backrest plate is longer than the distance from the support shaft to the lower end of the press when the surface provided with the pressing portion is located forward. ing. Therefore, if the seater leans back in that state,
The load due to the backward tilt is applied to the upper part, which is located at a longer distance from the support shaft, and the lower pressing end, which is located at a shorter distance, presses against the lower back of the seater. As a result, due to the balance of the mohement, a force larger than the load at the load point is obtained at the pressing portion. As a result, the sitting person can receive a particularly strong pressing force concentrated on the lower part of the back, and can obtain great physical comfort accompanied by an acupressure effect.
