Description

本発明は、バランスボール等のボールを配した座椅子に関する。The present invention relates to a seat chair provided with a ball such as a balance ball.

従来より、和室等で使用される座椅子においては、一般に緩衝性を有する座面と背もたれとで構成され、通常背もたれが角度調節金具により座面と起伏自在に連結されており、これを使用する場合、使用目的に応じて背もたれは最も快適な状態に角度調節される。例えば、読書等においては背もたれを起立状態とし、また仮眠や休息をとる場合には、背もたれを倒した状態に角度調節される。Conventionally, seat chairs used in Japanese-style rooms, etc. are generally composed of a cushioning seat surface and a backrest, and the backrest is usually connected to the seat surface with an angle adjustment bracket so that it can be raised and lowered. When doing so, the backrest is angled to the most comfortable state according to the purpose of use. For example, in reading or the like, when the backrest is in an upright state, and when taking a nap or rest, the angle is adjusted so that the backrest is tilted down.

座椅子は、両足を前方に投げ出したり胡坐をかいたりした状態で使用するため、長時間そのままの姿勢で着座している為、腰に負担がかかり、腰痛を惹き起こす原因になった。Since the sitting chair is used with both feet thrown forward or crossed, it sits in a posture for a long time, which puts a burden on the waist and causes back pain.

Means to solve the problem

上記問題点を解決するために、本発明の請求項１に係わる座椅子は、背もたれが座面に対し、起伏自在に連結された緩衝材を有する座椅子において、薄型緩衝材入り連結部、緩衝材入り補助具、中空状の取付具等、ボール、フック付きのゴムバンドから成る。In order to solve the above-mentioned problems, a seat chair according to claim 1 of the present invention is a seat chair having a cushioning material whose backrest is coupled to the seat surface so as to be able to be raised and lowered. It consists of a rubber band with a ball and a hook, such as an auxiliary tool with a cushioning material and a hollow fitting.

緩衝材入り補助具が、折り曲げ可能な薄型緩衝材入り連結部をはさんで座面に接続されており、また、座椅子の適当な位置、例えば、背もたれの左右両側の上下に中空状の取付具等を設け、そこにフック付きゴムバンドが取り付けられ、このフック付きゴムバンドによりボールを配置可能としたことを特徴とする。A cushioning auxiliary tool is connected to the seating surface with a foldable thin cushioning coupling part in between, and a suitable position of the seating chair, for example, a hollow shape at the top and bottom of the left and right sides of the backrest. An attachment tool or the like is provided, and a rubber band with a hook is attached thereto, and the ball can be arranged by the rubber band with a hook.

ボールを背もたれと座面に当接させ、座椅子の適当な位置、例えば、背もたれの左右両側の上下に設けた中空状の取付具等にフック付きゴムバンドを、ボールの中央で交差して取り付ける。The ball is brought into contact with the backrest and the seating surface, and a rubber band with a hook is crossed at the center of the ball at an appropriate position of the seat, for example, a hollow fitting provided on the upper and lower sides of the backrest. Install.

座椅子にボールを配置可能とすることにより、腰への負担が減るため、長時間快適に着座することができる。また、使用者の背中をボールに寄りかかり臨ませ、うでを左右に振ることにより、おなか周り等の運動が出来、両手を上方に挙げ、上体をボールにもたれ掛ける事により、着座しながら背筋を伸ばすことができ、心地よい刺激を得るストレッチ運動を行うことができるので、さらに腰痛になりにくくすることが出来る。By making it possible to place the ball on the seat, the burden on the waist is reduced, so that the user can sit comfortably for a long time. In addition, the user's back leans against the ball, swings his / her left and right, and exercises around the tummy, raises both hands upwards, leans the upper body against the ball, sits down while sitting Can be stretched, and a stretching exercise that obtains a pleasant stimulus can be performed, which can further reduce back pain.

なお、本発明の座椅子は前記補助具が、薄型緩衝材入り連結部をはさんで接続されているので該連結部等に臀部を当接させ、補助具により体を安定させることにより、体を崩しリラックスする等、使用範囲の拡大を図ることが可能となる。In the seat chair of the present invention, the auxiliary tool is connected with the thin buffer member-containing connecting part interposed therebetween, so that the buttocks abut against the connecting part and the like, and the body is stabilized by the auxiliary tool. It is possible to expand the range of use, such as breaking down and relaxing.

The invention's effect

本発明は以上のように、座椅子に半固定されたボールに腰部が当接されるので長時間座っていても腰への負担が軽減され、また、体を崩して座る場合には、連結部等に臀部を置き、補助具により、体を安定させることが出来る。さらにストレッチやボール運動が座って行なえる為、腰痛を起こしにくくさせることが出来る。The present invention, as described above, reduces the burden on the waist even when sitting for a long time because the waist is in contact with the ball semi-fixed to the seat chair, The body can be stabilized by placing an eaves part on the connecting part or the like and using an auxiliary tool. In addition, stretching and ball exercises can be performed while sitting, making it difficult to cause back pain.

以下、本発明の一実施例を図面に基づき説明する。図１は本発明の平面図で、図２は本発明の正面図、図３は本発明の側面図、図４は本発明の斜視図、図５は本発明に肘掛を追加させ使用している状態を示す側面図である。本発明の座椅子（１）は、緩衝性に優れた座面（２）と背もたれ（３）とを備えており、背もたれ（３）は、角度調節金具（図示せず）により座面（２）に対して１８０℃起伏自在に連結されている。かかる座椅子（１）の構造自体は既知のものを採用することができ、特に改良を要するものではない。Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a plan view of the present invention, FIG. 2 is a front view of the present invention, FIG. 3 is a side view of the present invention, FIG. 4 is a perspective view of the present invention, and FIG. It is a side view which shows the state which exists. The seat chair (1) of the present invention includes a seat surface (2) and a backrest (3) excellent in shock-absorbing properties, and the backrest (3) is mounted on the seat surface (not shown) by an angle adjusting bracket (not shown). 2) is connected to be freely raised and lowered at 180 ° C. As the structure of the seat chair (1), a known structure can be adopted, and no particular improvement is required.

座椅子（１）の座面（３）に、折り曲げ可能な薄型緩衝材入り連結部（４）に続き、緩衝材入り補助具（５）が接続されている。A cushioning material-containing auxiliary tool (5) is connected to the seat surface (3) of the seat chair (1), following the connecting portion (4) with a thin cushioning material that can be bent.

また、座椅子（１）の適当な位置、例えば背もたれ（２）の左右両側の上下に中空状の取付具（６）等を設け、そこにフック付きゴムバンド（７）が取り付けられる様になっている。In addition, hollow fittings (6) and the like are provided at appropriate positions of the seat (1), for example, on the left and right sides of the backrest (2), and a rubber band (7) with a hook is attached thereto. It has become.

本発明を使用するときは、座椅子（１）の背もたれ（２）と座面（３）にボール（８）を当接させ、座椅子（１）の適当な位置、例えば、背もたれ（２）の左右両側の上下に設けた中空状の取り付け具（６）等にフック付きのゴムバンド（７）をボール（８）の中央で交差させて取り付け、ボール（８）を半固定させる。When using the present invention, the ball (8) is brought into contact with the backrest (2) and the seating surface (3) of the seat (1), and the seat (1) is placed at an appropriate position, for example, the backrest ( 2) A rubber band (7) with a hook is crossed at the center of the ball (8) and attached to hollow fittings (6) provided on the upper and lower sides of the left and right sides, and the ball (8) is semi-fixed.

運動時には、使用者の背中をボール（８）に寄りかかり臨ませ、両うでを左右に振る事により、おなか周りの運動が、また、両腕を上方に挙げ、上体をボール（８）にもたれ掛ける事により、着座しながら背筋を伸ばすことができ、心地よい刺激を得るストレッチ運動を行うことができるので、さらに腰痛を妨げることが出来る。（図示せず）。When exercising, lean the user's back against the ball (8), swing both arms to the left and right to move around the tummy, raise both arms upwards, and raise the upper body to the ball (8) By leaning, the back muscles can be stretched while sitting, and a stretching exercise that obtains a pleasant stimulus can be performed, further preventing back pain. (Not shown).

運動しないときには、ボール（８）が座椅子（１）の一部になりエアークッションの役目をはたし、長時間着座していても腰への負担が軽減され、また、体を崩しリラックスして座る場合には、薄型の緩衝材入りの連結部（４）等に臀部を当接させ、緩衝材入りの補助具（５）により、体を安定させることで、座り心地の良い座椅子（１）を提供することが出来る。When not exercising, the ball (8) becomes a part of the chair (1) and acts as an air cushion, reducing the burden on the hips even when sitting for a long time, and also breaking down and relaxing When sitting in a comfortable position, the heel part is brought into contact with the thin connecting part (4) containing a cushioning material and the body is stabilized by the auxiliary tool (5) containing the cushioning material.
