A stopper is strengthened so that the backrest is not tilted from the vertical state to an angle of 45° or more, and fixing of elongation and contraction of the energizing device is released to take exercise for back muscle, abdominal muscle, and quadriceps muscle of thigh without load on the waist. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【産業上の利用分野】
この発明は、高齢者や病弱者を含む一般人のための座椅子および座椅子状の運動機器に関する。
【0002】
【従来の技術】
従来の座椅子は、単に背当ての段階的リクライニングならびに折り畳みができるだけで、背筋、腹筋、大腿四頭筋などの運動による身体の機能回復や、筋力訓練およびシェープアップに役立つものではなく、また座椅子を利用した運動機器はこれまで例がなかった。
【0003】
【発明が解決しようとする課題】
従来の座椅子ではできなかった、身体の機能回復や、筋力訓練およびシェープアップ効果を持たせることができ、併せて背当てをフルリクライニングまでの任意の角度に固定し、且つ折り畳みが可能な座椅子を提供することを課題とする。
【0004】
背筋、腹筋、大腿四頭筋などの運動の際には、大腿部と体幹との間の角度が約130°の時に最も腰に負担が掛からないことが知られている。従って座面の迎角を5°とした時、運動時の背当ての最大傾斜角度が垂直から約45°後方へ倒した状態となるように、ストッパーを設ける必要がある。
【0005】
また、一般用の座椅子としては、背当てを後方へほぼ水平までの任意の角度で固定できる必要があり、また収納のためには、どの角度からも背当てを前方に倒して折り畳むことが求められる。
【0006】
【課題を解決するための手段】
ベースフレームに保持されて背当てを傾動できる座椅子において、座面フレームに対する背当てフレームの回転軸に揺動部材を枢着し、この揺動部材の下端部と座面フレームまたはベースフレームとの間に、伸縮行程の任意の位置に固定でき、且つ固定を解除できる付勢装置を取り付け、背当てフレームの下端部を該揺動部材で支えるようにし、この付勢装置の最長状態の時に背当てがほぼ垂直に立つようにし、また付勢装置の最短状態の時に背当てがほぼ水平に後方に倒れるようにし、且つ、背当てを任意の角度から前方に折り畳むことができるように構成する。
【0007】
座面フレームに対する背当てフレームの回転軸に枢着された揺動部材の、該回転軸の後方に設けた支持軸を、ベースフレームに設けた支持ブラケットに枢着し、座面フレームの前部をベースフレームとの間に設けた斜め方向のリンクまたは案内機構で支持し、背当ての傾動に伴なう該揺動部材の回転と連動して座面フレームを昇降させるように構成する。
【0008】
この揺動部材の回転軸と、座面フレームの前部とベースフレームとの間に設けた斜め方向のリンクまたは案内機構を適切に設定することによって、背当ての角度が垂直から後方約45°までの間は、座面の迎角をほぼ5°に保ち、傾動中の人体の姿勢を安定させることができる。またさらに、体重の加わった状態での座面フレームの昇降により、付勢装置の反発力を補助する効果がある。
【0009】
ベースフレームと背当ての下部との間にストッパーを設け、背当てが後方へ垂直から約45°以上倒れないようにし、該ストッパーを移動または反転させて背当てをほぼ水平状態まで後方に倒れるようにすることができるように構成する。
付勢装置の固定を解除した状態で、このストッパーを設けた時、背筋、腹筋、大腿四頭筋などの運動の際には、座面と背当ての角度が最大約130°となって、運動時の腰への負担が少なくなり、従来の座椅子ではできなかった身体の機能回復や、筋力訓練およびシェープアップ効果を持たせることができる。
【0010】
【実施例】
以下、本発明の具体的な実施例について、図面に沿って詳述する。
図1は、本発明の座椅子の、背当てを最も立てた状態を示す側面図である。
図2は、背当てを後方へ約45°倒した状態を示す側面図である。
図3は、背当てを後方へほぼ水平まで倒した状態を示す側面図である。
図4は、背当てを前方へ倒した状態を示す側面図である。
【0011】
床面1によって支えられるベースフレーム2の後部には、支持ブラケット3が設けられ、この上部に揺動部材4を枢着する支持軸5が設けられる。揺動部材4の一端には、背当てフレーム6のブラケット7および、座面フレーム8のブラケット9を枢着する支持軸10が設けられ、揺動部材4の他端には、付勢装置11の後端部12が取り付けられる。付勢装置11の前端部13は、座面フレーム8に設けられた支持軸14が取り付けられる。
【0012】
付勢装置11の前端部13にはまた、操作レバー15が設けられ、カム16によって伸縮行程の任意の位置に固定または解除することができる。揺動部材4には、クロスメンバー17が設けられ、背当てフレーム6の下端部18を支持する。ベースフレーム2の後部にはまた、背当てフレーム6が後方へ45°以上倒れないように、可倒式のストッパー19が設けられ、背当てフレーム6の下部を支持するようになっており、ストパーが必要ない時には、折り畳むことによって背当てを後方へ水平状態まで倒すことができる。
【0013】
ベースフレーム2の前部に設けられた支持軸20と、座面フレームの前部に設けられた支持軸21には、支持リンク22が取り付けられ、背当ての傾動によって揺動部材4の揺動と連動して座面を昇降させる。
【0014】
このように構成することによって、操作レバー15を回転させて付勢装置11の伸縮の固定を解除すると、付勢装置11の反発力によって、背当てが垂直付近まで立つことになるために、可倒式のストッパー19によって背当てを後方へ45°以上倒れないようにすると、座面の迎角をほぼ5°に保ちながら大腿部と体幹との間の角度が約130°の範囲で、座面に加わる体重と、付勢装置11の反発力を併せて利用して屈伸運動を行うことができる。
【0015】
可倒式のストッパー19を解除し、背当てを水平状態までの任意の角度で、操作レバー15を回転させて付勢装置11の伸縮を固定することによって、通常の座椅子として使用することができ、また背当てを任意の角度から前方に折り畳むことができる。なお、背当てを後方へ水平状態まで倒した時には、座面の迎角もほぼ0°となり、簡易なベッドとしても使用できる。
【0016】
【発明の効果】
本発明の座椅子は、背当ての角度を無段階で調節することができる、通常の座椅子として使用することができるばかりでなく、ストッパーを利かせることによって、背当ての傾動の範囲を、座面と背当ての角度がほぼ90°から130°の範囲に限定した屈伸運動を行うことができ、腰に負担を掛けずに、背筋、腹筋、大腿四頭筋などの筋力の回復、機能訓練、シェイプアップに役立つ効果がある。
【0017】
背当てを後方へ水平状態まで倒した時には、座面の迎角もほぼ0°となって、連続した水平面を構成することになり、簡易なベッドとしても使用できる。また背当てを任意の角度から前方に折り畳むことによって間単に収納できる効果がある。
【0018】
背当てを傾動させて屈伸運動を行う時、連動して座面を昇降させるため、付勢装置の反発力に座面に加わる体重が加わって背当ての復元力が増すため、付勢装置に掛かる負荷を減らして小型化することができるとともに、付勢装置の揺動スペースも確保しやすい構成とすることができる効果がある。

[0007]
A support shaft of a swing member pivotally mounted on a rotation shaft of the backrest frame with respect to the seat frame is pivotally mounted on a support bracket provided on the base frame, and a front portion of the seat frame is provided. Is supported by an oblique link or a guide mechanism provided between the base frame and the base frame, and the seat frame is moved up and down in conjunction with the rotation of the swinging member accompanying the tilt of the backrest.
[0008]
By appropriately setting the rotation axis of the rocking member and the diagonal link or guide mechanism provided between the front portion of the seat frame and the base frame, the angle of the backrest is approximately 45 ° rearward from vertical. In the meantime, the angle of attack of the seat surface is maintained at approximately 5 °, and the posture of the tilting human body can be stabilized. Further, the lifting and lowering of the seat frame with the weight applied has an effect of assisting the repulsive force of the urging device.
[0009]

[0014]
With this configuration, when the operation lever 15 is rotated to release the fixed expansion and contraction of the urging device 11, the repulsive force of the urging device 11 causes the backrest to stand up to near a vertical position. When the backrest is prevented from falling over 45 ° by the fall-down stopper 19, the angle between the thigh and the trunk is about 130 ° while maintaining the angle of attack of the seat surface at about 5 °. In addition, it is possible to perform the bending and stretching exercise by using the weight applied to the seat surface and the repulsive force of the urging device 11 together.
[0015]
By releasing the retractable stopper 19 and rotating the operating lever 15 at an arbitrary angle up to the horizontal state to fix the expansion and contraction of the biasing device 11, it can be used as a normal chair. And the backrest can be folded forward from any angle. When the backrest is tilted rearward to the horizontal state, the angle of attack of the seat surface is almost 0 °, and the seat can be used as a simple bed.
[0016]
【The invention's effect】
The seat chair of the present invention can be used as a normal seat chair in which the angle of the backrest can be adjusted steplessly, as well as the tilting range of the backrest by using the stopper. Can perform flexion and extension exercises with the angle between the seat and backrest limited to approximately 90 ° to 130 °, restoring muscle strength of the back, abdominals, quadriceps, etc. without straining the lower back , Functional training, has the effect of helping shape up.
[0017]
When the backrest is tilted rearward to a horizontal state, the angle of attack of the seat surface is also substantially 0 °, and a continuous horizontal surface is formed, so that the seat can be used as a simple bed. Further, there is an effect that the backrest can be easily stored by folding the backrest forward from an arbitrary angle.
[0018]
When tilting the backrest to perform bending and stretching movements, the seat surface is raised and lowered in conjunction with it, so the weight added to the seat surface is added to the repulsive force of the biasing device and the restoring force of the backrest increases, so the It is possible to reduce the size of the load by reducing the applied load, and to provide a configuration in which a swing space for the urging device can be easily secured.
