Description

本発明は、オットマンが付属する椅子式マッサージ機に関するものである。   The present invention relates to a chair type massage machine to which an ottoman is attached.

従来から座部の前端に足載せ用のオットマンを回動自在に連結した椅子式マッサージ機が提供されているが、上記オットマンが足裏を載せる部分を有している場合、オットマンを回動させて足先側を高くした時、膝や下腿部がオットマンから浮き上がってしまうために、下肢をリラックス状態にできない上に、オットマンにマッサージ手段を設けたものでは下肢へのマッサージ手段によるマッサージを効果的に行えなくなる。   Conventionally, a chair type massage machine has been provided in which a foot ottoman is rotatably connected to the front end of the seat, but when the ottoman has a portion on which the sole is placed, the ottoman is rotated. When the toe side is raised, the knees and lower leg parts will rise from the ottoman, so the lower limbs cannot be in a relaxed state, and if the ottoman is provided with massage means, massage by the massage means to the lower limbs is effective Cannot be performed.

このために、オットマンにおける足裏を載せる部分をオットマンの回動時に常にほぼ水平状態を保つようにしたものや、特開２００４−２０１９１６号公報（特許文献１）に示されているように、座部に回動自在に連結された支持フレームを設けて、この支持フレームにオットマンをスライド自在に装着したものが提供されている。   For this reason, as shown in Japanese Patent Application Laid-Open No. 2004-201916 (Patent Document 1), the part on which the sole of the ottoman is placed is always kept almost horizontal when the ottoman rotates. There is provided a support frame that is pivotally connected to a portion and in which an ottoman is slidably mounted on the support frame.

前者の場合は、オットマンを回動させて水平近くまで上げた時にも、オットマンから下肢が浮き上がることがないようにできるが、オットマンに設けたマッサージ手段と下肢とがずれてしまう上に、足裏へのマッサージができないものとなる。   In the former case, the lower limbs can be prevented from lifting from the ottoman even when the ottoman is rotated and raised to near horizontal, but the massage means provided on the ottoman and the lower limbs are displaced, and It will be impossible to massage.

後者であれば、マッサージ手段と下肢とがずれてしまうこともなく、また足裏用のマッサージ手段を設けたものでは足裏へのマッサージをオットマンの回動角度に関係なく行うことができるが、オットマンをスライドさせて引き出した状態のままでオットマンを降ろす方向に回動させた場合、座部の高さの関係からオットマンが床面に接地してしまう。   If it is the latter, the massage means and the lower limb will not be displaced, and in the case where the massage means for the sole is provided, the massage to the sole can be performed regardless of the rotation angle of the ottoman, When the ottoman is slid and pulled out and is rotated in the direction in which the ottoman is lowered, the ottoman contacts the floor due to the height of the seat.

この時、図２に示すように、オットマン４がある傾きを有して上記接地点が椅子１に近い時、オットマン４における足裏を載せる部分４２に体重Ｗをかけると、座部２とオットマン４（支持フレーム２１）との回動連結点２０を持ち上げることになる力Ｆが作用するとともに、上記体重Ｗが椅子１の重さ（マッサージ機構が組み込まれていることからほぼ８０ｋｇ）とほぼ同じであったり重かったりした場合、図２(b)に示すように上記回動連結点２０が持ち上げられることになる。   At this time, as shown in FIG. 2, when the ottoman 4 has a certain inclination and the grounding point is close to the chair 1, when the weight W is applied to the portion 42 where the sole of the ottoman 4 is placed, the seat 2 and the ottoman 4 4 (support frame 21) and a force F that lifts the pivotal connection point 20 acts, and the weight W is substantially the same as the weight of the chair 1 (approximately 80 kg because the massage mechanism is incorporated). If it is heavy or heavy, the pivot connecting point 20 is lifted as shown in FIG.

上記の動きは、椅子１側の接地部の動きを伴うために、この接地部に滑り止め部材２６を貼り付けておくことで、持ち上がりにくくすることができるが、床面の摩擦係数が低い場合など、それでも図２(b)に示す動きが生じることがある。
特開２００４−２０１９１６号公報 Since the above movement is accompanied by the movement of the grounding part on the chair 1 side, it is possible to make it difficult to lift by attaching the anti-slip member 26 to this grounding part, but when the friction coefficient of the floor surface is low However, the movement shown in FIG. 2 (b) may still occur.
JP 2004-201916 A

本発明は上記の従来の問題点に鑑みて発明したものであって、オットマンにおける足裏を載せる部分を踏みつけてしまっても椅子が不用意に動いたりすることがない椅子式マッサージ機を提供することを課題とするものである。   The present invention was invented in view of the above-described conventional problems, and provides a chair-type massage machine in which a chair does not move inadvertently even if a foot on a foot of an ottoman is stepped on. This is a problem.

上記課題を解決するために本発明に係る椅子式マッサージ機は、座部を有する椅子と、座部の前端に回動自在に連結された支持フレームと、この支持フレームにスライド自在に装着されたオットマンとを備えるとともに、該オットマンが人体の足裏を支える支持部をその端部に備え、上記支持フレームの回動に伴い、上記支持フレームに対して引き出されたオットマンの上記足裏を支える支持部の底部における先端側が床面から離れた状態で上記底部における椅子側の端部が床面に接地する椅子式マッサージ機において、上記支持部の底部における椅子側の端部よりも支持部の先端寄りにおいて床面と接地する突部を支持部の底部に設けていることに特徴を有している。接地点が支持部の椅子側の端部よりも支持部の先端寄りに突部によってずらされていることで、座部とオットマン側との回動連結点を持ち上げる力が作用しにくくなるようにしたものである。 In order to solve the above problems, a chair type massage machine according to the present invention is a chair having a seat, a support frame rotatably connected to the front end of the seat, and slidably attached to the support frame. An ottoman and a support portion that supports the sole of the human body at the end thereof, and supports the sole of the ottoman that is pulled out with respect to the support frame as the support frame rotates. In the chair type massage machine in which the end on the chair side in the bottom is grounded to the floor in a state where the front end side in the bottom of the part is separated from the floor , the tip of the support part is more than the end on the chair side in the bottom of the support It is characterized in that a projecting portion that contacts the floor surface is provided at the bottom of the support portion. The grounding point is shifted by the protrusion closer to the tip of the support part than the chair side end of the support part, so that the force to lift the rotation connection point between the seat part and the ottoman side is less likely to act It is a thing.

上記突部は弾性体で形成されていることが好ましい。荷重が加わった時に弾性変形によって接地面積が広がるために、上記の持ち上げる力が作用しにくくなるものである。   The protrusion is preferably formed of an elastic body. When the load is applied, the ground contact area is expanded due to elastic deformation, so that the lifting force is difficult to act.

本発明は、オットマンの足裏を支持する支持部の先端を踏んだ場合にも、オットマンの接地点を支点としてオットマン側と座部との回動連結点を持ち上げようとする力がさほど大きくならないために、上記回動連結点が持ち上がってしまうようなことがないものである。   In the present invention, even when the tip of the support portion that supports the sole of the ottoman is stepped on, the force to lift the rotational connection point between the ottoman side and the seat portion with the ottoman's grounding point as a fulcrum is not so great. For this reason, the rotation connecting point is not lifted up.

以下、本発明を添付図面に示す実施形態に基いて説明すると、図示例の椅子式マッサージ機は、座部２とマッサージ機構が組み込まれた背もたれ３とを有する椅子１における座部２の前端部に、支持フレーム２１を回動自在に連結するとともに、この支持フレーム２１にオットマン４をスライド自在に装着したもので、上記支持フレーム２１は椅子１側との間に設けられた伸縮式アクチュエータ（図示せず）による駆動で回動を行う。   Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. A chair type massage machine in the illustrated example is a front end portion of a seat portion 2 in a chair 1 having a seat portion 2 and a backrest 3 incorporating a massage mechanism. Further, the support frame 21 is rotatably connected, and the ottoman 4 is slidably mounted on the support frame 21, and the support frame 21 is provided with a telescopic actuator (see FIG. Rotation is performed by driving by (not shown).

支持フレーム２１と共に回動することになるオットマン４は、使用者のふくらはぎを支えることになる支持部４１と、使用者の足裏を支えることになる支持部４２とを備えたもので、これら支持部４１，４２には夫々エアポンプに接続されて膨張収縮することでふくらはぎや足裏に対してマッサージを行う空気袋（図示せず）が配設されているとともに、これらの外面を覆うカバー４０を備えたものとなっている。   The ottoman 4 that rotates together with the support frame 21 includes a support portion 41 that supports the user's calf and a support portion 42 that supports the sole of the user. Each of the portions 41 and 42 is provided with an air bag (not shown) that is connected to an air pump and expands and contracts to massage the calves and soles, and a cover 40 that covers these outer surfaces is provided. It has become a preparation.

合成樹脂などで形成された剛性を有している上記カバー４０における底面には、突部４４が設けられている。カバー４０底面における椅子１側の角部に設けられた上記突部４４は、オットマン４における床面との接地点を椅子１から遠くなる方にずらすためのもので、支持フレーム２１に対してオットマン４を少しだけ引き出した状態でカバー４０を接地させた時、本来ならば、座部２と支持フレーム２１との回動連結点２０からカバー４０における接地点までの水平距離をＬ２、カバー４０における接地点から上記支持部４２の先端までの水平距離をＬ１とする時、Ｌ１＞Ｌ２となるために、支持部４２の先端に体重Ｗを加えた場合、てこ比の関係で上記回動連結点２０が持ち上げられてしまうのに対して、上記突部４４は床面との接地点を椅子１から遠ざけて、支持部４２の先端側にずらすために、上記Ｌ１とＬ２とがほぼ等しい値、もしくはＬ１＜Ｌ２となるものであり、椅子側の重量にもよるものの、突部４４を設けていない場合に比して、回動連結点２０が持ち上げられてしまうことが殆ど無いものとなる。   A protrusion 44 is provided on the bottom surface of the cover 40 having rigidity formed of synthetic resin or the like. The protrusions 44 provided at the corners on the chair 1 side on the bottom surface of the cover 40 are for shifting the ground contact point with the floor surface of the ottoman 4 away from the chair 1. When the cover 40 is grounded with 4 slightly pulled out, the horizontal distance from the pivotal connection point 20 between the seat portion 2 and the support frame 21 to the grounding point in the cover 40 is originally L2. When the horizontal distance from the contact point to the tip of the support portion 42 is L1, L1> L2, so that when the weight W is added to the tip of the support portion 42, the pivot connection point is related to the lever ratio. 20 is lifted, while the protrusion 44 moves the grounding point with the floor surface away from the chair 1 and shifts to the front end side of the support portion 42, the L1 and L2 are substantially equal values, Or L <Is intended to be L2, although it depends on the weight of the chair-side, in comparison with the case provided with no projection 44, it becomes it is seldom pivotal connecting point 20 will be lifted.

なお、オットマン４を支持フレーム２１に対してかなり引き出している状態では、カバー４０が接地する時は図中の角度αが大きく、上記Ｌ１，Ｌ２の値が元々Ｌ１＜Ｌ２であるために、突部４４が機能しなくてもよい。   In the state where the ottoman 4 is considerably pulled out with respect to the support frame 21, when the cover 40 is grounded, the angle α in the drawing is large, and the values of L1 and L2 are originally L1 <L2. The part 44 may not function.

また、ここでは突部４４を弾性体で形成するとともに、加重が加わった時の弾性変形で突部４４における接地面が椅子１から遠ざかる方向において、線接触もしくは複数箇所で接地するような形状とすることで、より安定した状態を保つことができるようにしている。   Further, here, the protrusion 44 is formed of an elastic body, and has a shape such that the grounding surface of the protrusion 44 moves away from the chair 1 due to elastic deformation when a load is applied, and is in line contact or grounded at a plurality of locations. By doing so, it is possible to maintain a more stable state.
