Abstract

(57) [Summary] [Purpose] In general chairs, especially office or study chairs, the buttrest where people sit is usually horizontal, and the backrest is almost vertical. However, when this chair is used for a long time, the entire body weight of the upper body is hung on the buttocks of the chair, which often causes fatigue and pain in the lower back. [Constitution] The chair of the present invention tilts the buttocks against the front about 5 °
By tilting the back support plate backward by about 12 ° and attaching the shin support plate to the height and angle freely in order to prevent the inversion of both legs due to the backward tilt of the upper body, the body weight of the upper body when sitting is reduced And the backrest plate and the shin receiving plate are distributed and weighted, so that the burden on the waist is extremely reduced, and the user does not feel tired or pain.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a chair that disperses the weight of the upper body when sitting and places no burden on the lower back. .

[0002]

[Prior art]

 Ordinary chairs, particularly office or study chairs, usually have a horizontal buttocks on which people sit, and a nearly vertical backrest. Often, the entire upper body weight rests on the buttocks of the chair, causing tiredness and pain in the lower back.

[0003] The present invention is intended to improve the above-mentioned difficulties of the conventional chair and to provide a chair which does not burden the waist.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, the hip rest of the chair on which the buttocks are to be tilted forward by about 5 °, the backrest plate is tilted backward by about 12 ° with respect to the hip rest, and the rear leg (6) is further tilted by about 12 °. It is designed to hold the shin abutment plate for receiving the shin with a support plate attached to a part of the chair in order to prevent the legs from reversing due to the backward tilt of the upper body when sitting and sitting 10 degrees backward. is there.

[0005]

[Action]

 When sitting in a chair configured as described above, the weight of the upper body is distributed and weighted to the backrest plate and the shin receiving plate outside the buttocks, so that the burden on the waist is greatly reduced.

[0006]

【Example】

 An embodiment shown in the drawings will be described. FIG. 1 shows the case of a chair having four legs. That is, in this case, the buttocks 4 on which the buttocks are placed are inclined forward by about 5 ° from the horizontal plane, and the backrest plate 1 is inclined backward by about 12 ° from the vertical plane. Here, the shin receiving plate 2 which receives the reversing force of the shin of both feet due to the backward tilt of the upper body is held by the support plate 3 attached to the pair of front and rear legs 6 and 7 on the left side. As shown in FIG. 2, the support plate 3 has a support portion 3b inserted into a sheath portion 3a so as to be able to expand and contract, and the sheath portion 3a and the support portion 3b have a large number of through holes c and d, respectively. Are provided at equal intervals, and a U-shaped boat is inserted into each and the height and angle can be freely set. The support plate (3) can be attached to a pair of front and rear legs on the right side of the chair as necessary.

FIG. 3 shows the case of a swivel chair that supports the hip backing plate 4 rotatably with one column. That is, in this case, a pair of “shaped fittings 5, 5 having a plurality of through-holes e is fixedly suspended from either the left or right side edge of the bottom surface of the buttocks 4, and this is attached to the shin receiving plate 2. The support plate 3 is mounted at a position maintaining an appropriate height and angle by using an upper bolt and a nut in which the respective through holes e and f of the support plate 3 for supporting the support plate 3 are aligned. It is more preferable that an appropriate elastic material such as cloth is attached to the surface of the shin receiving plate 2 and the backing plate 1 outside the buttocks 4.

[0008]

[Effect of the invention]

 As described above, the chair according to the present invention has a butt pad that is tilted forward by about 5 ° and a back plate that is tilted backward by about 12 °. The upper body is weighted approximately 50% on the buttocks and approximately 25% each on the back and shin receiving plates when sitting down. The burden is greatly reduced and fatigue and pain are hardly felt.
