Abstract

PROBLEM TO BE SOLVED: To provide a legless chair which can reduce force loaded on the knees by raising its seat surface height though it is hard particularly for an aged person or a person with weak legs to stand up when having meal sitting on a legless chair or warming him-/her-self up in a kotatsu (Japanese foot warmer).SOLUTION: A pantograph type jack 5 is set on an inside space of armrests 3 in both sides of a seat surface of the legless chair. The jack is driven by a motor 4 to raise the legless chair body 1 high.

Description

本発明は、立ち上がることを楽にするために、座椅子本体を持ち上げて、結果として人が座る座面を高くするようにしたものである。In the present invention, in order to make it easy to stand up, the seat body is lifted, and as a result, the seat surface on which a person sits is made higher.

従来は座面を高くすることが出来る座椅子はなかった。Previously, there was no seat chair that could raise the seat surface.

座椅子に長く座っていると、足の弱い人や年寄りなどは立ち上がるのが苦痛であった。
本発明は、この課題を解消するためになされたものである。When sitting on a chair for a long time, people with weak legs and elderly people had difficulty getting up.
The present invention has been made to solve this problem.

座椅子の座面を高くすれば立ち上がるとき膝にかかる力が軽減するので、そのためには、油圧ポンプや種々の歯車の組合わせも考えられるが、本発明では、座椅子の本体と底板（土台板）を分離して、パンタグラフ式の電動ジャッキを座面左右の肘掛けの内部に設置して、座椅子本体を容易に持ち上げるようにした。Since the force applied to the knee when standing up is reduced if the seat surface of the seat chair is raised, a combination of a hydraulic pump and various gears can be considered for this purpose. The base plate was separated, and a pantograph-type electric jack was installed inside the armrests on the left and right sides of the seat so that the seat body could be easily lifted.

本発明によって、座椅子から立ち上がる際の膝にかかる力を軽減することが出来て、足の弱い人や老人でも座椅子から楽に立ち上がることが出来るようになった。According to the present invention, it is possible to reduce the force applied to the knee when standing up from a seat chair, and even a person with weak legs or an elderly person can easily stand up from the seat chair.

本発明に関わる座椅子の斜面図である。It is a slope view of the seat chair in connection with this invention. 本発明に関わる座椅子の俯瞰図である。It is an overhead view of the seat chair in connection with this invention. 本発明の座椅子本体が下がっている状態を示す断面図である。It is sectional drawing which shows the state which the seat main body of this invention is falling. 本発明の座椅子本体が上がっている状態を示す断面図である。It is sectional drawing which shows the state which the seat main body of this invention has gone up.

以下、本発明の実施の形態について説明する。
（イ） 座椅子を座面と底板（土台板）とに分けて、座面の左右にある肘掛けの内部のスペースにパンタグラフ式のジャッキを収納する。
（ロ） ジャッキの中心のねじ棒が回ってジャッキが上に動いたときに、底板を起点にして座椅子本体が持ち上がるように工作する。下げるときはモーターを逆回転させればよい。なおジャッキのねじ棒を回すモーターは、共回りをしないように工夫されなくてはならない。Embodiments of the present invention will be described below.
(B) Divide the seat chair into a seat and a bottom plate (base plate), and store pantograph jacks in the space inside the armrests on the left and right sides of the seat.
(B) When the screw rod at the center of the jack rotates and the jack moves up, work so that the seat body rises from the bottom plate. When lowering the motor, reverse the motor. The motor that turns the screw rod of the jack must be devised so as not to rotate together.
