実施例1について図1及び図2を用いて説明する(特に請求項1、請求項3及び請求項5に対応)。
図1(a)は本発明の実施の形態に係る起立補助装置の実施例1の斜視図であり、(b)及び(c)は実施例1の起立補助装置の側面図である。
図1(a)に示すように、本実施例の起立補助装置1aは、断面コの字状の平板からなる上面板2及び基底板3と、上面板側面2bの後部にその端部4b,4bが回動自在に軸支される掛止手段4と、基底板3の後端から一部を突出するように基底板平面3aに設置される止具5とを備えるものである。そして、上面板側面2bの前部は基底板側面3bの前部に設置された軸6に回動可能に取り付けられ、基底板側面3bには掛止手段4の端部4bより大きな径の半円状の切欠部7が設けられ、止具5には掛止手段4の掛止部4aが滑動するスライド部8aと、そのスライド部8aの前部に掛止部4aが掛止可能な突出部8が設けられている。
The first embodiment will be described with reference to FIGS. 1 and 2 (particularly corresponding to claims 1, 3 and 5).
Fig.1 (a) is a perspective view of Example 1 of the standing assistance apparatus which concerns on embodiment of this invention, (b) and (c) are side views of the standing assistance apparatus of Example 1. FIG.
As shown in FIG. 1A, the standing assisting device 1a of the present embodiment includes an upper surface plate 2 and a base plate 3 made of a U-shaped flat plate, and an end portion 4b at the rear portion of the upper surface plate side surface 2b, A latching means 4 on which 4b is pivotally supported and a stopper 5 installed on the base plate plane 3a so as to partially protrude from the rear end of the base plate 3 are provided. The front portion of the top plate side surface 2b is rotatably attached to a shaft 6 installed at the front portion of the base plate side surface 3b, and the base plate side surface 3b has a half diameter larger than that of the end portion 4b of the latching means 4. A circular notch 7 is provided, the stopper 5 has a slide part 8a on which the latching part 4a of the latching means 4 slides, and a protrusion on which the latching part 4a can be latched at the front part of the slide part 8a. A part 8 is provided.

このような構造の起立補助装置1aにおいては、基底板平面3aと上面板平面2aのなす角度が0度の場合(以下、上面板2を閉じた状態という。)、図1(b)に示すように、掛止手段4の端部4b,4bは基底板側面3bの切欠部7に嵌合し、また、掛止部4aは止具5のスライド部8aの最後方に位置しており、上面板平面2aは基底板平面3aと略平行になる。そして、上面板2を閉じた状態から方向Aで示す向きに徐々に開いていくと、掛止部4aは止具5のスライド部8aの上面を方向Bで示す向きに滑動し、やがて、図1(c)に示すように、止具5の突出部8に掛止する。従って、上面板2は所定の角度以上に傾動することがない。   In the standing assist device 1a having such a structure, when the angle formed by the base plate plane 3a and the upper plate plane 2a is 0 degree (hereinafter referred to as a state in which the upper plate 2 is closed), it is shown in FIG. Thus, the end portions 4b and 4b of the latching means 4 are fitted into the notch portion 7 of the base plate side surface 3b, and the latching portion 4a is located at the end of the slide portion 8a of the stopper 5.

Then, when the upper surface plate 2 is gradually opened from the closed state in the direction indicated by the direction A, the latching portion 4a slides in the direction indicated by the direction B in the upper surface of the slide portion 8a of the stopper 5, and eventually, FIG. As shown to 1 (c), it latches on the protrusion part 8 of the fastener 5. FIG. Therefore, the upper surface plate 2 does not tilt beyond a predetermined angle.

次に、起立補助装置1aを備えた椅子について図2を用いて説明する。
図2(a)及び(b)は実施例1の起立補助装置を備えた椅子の側面図である。なお、図1の構成要素と同じものについては、同一の符号を付してその説明を省略する。また、以下の説明において、椅子9aは略水平状態の床の上に設置されて使用されるものとする。
図2(a)に示すように、起立補助装置1aを備えた椅子9aは、キャスター10と支柱11からなる脚部12と、起立補助装置1aを介して脚部12の上部に設置される座部13と、フレーム14によって座部13に取り付けられる背もたれ15とから構成される。脚部12の上端には基底板平面3aが略水平に取り付けられ、座部13の下面には上面板平面2aが略水平に取り付けられている。従って、通常の使用状態では、座部13は略水平となっている。
これに対し、椅子9aに座っている利用者が前傾姿勢になって座部13の前端に方向Cで示す向きに体重をかけると、座部13は上面板2と一体となって軸6を中心として方向Aで示す向きに傾動する。
座部13の傾動に伴い、掛止手段4の掛止部4aは止具5のスライド部8aの上面を方向Bで示す向きに滑動するが、やがて、図2(b)に示すように、止具5の突出部8に掛止する。これにより、座部13の傾動は停止する。利用者が起立した後には、座部13や背もたれ15の自重によって掛止部4aは、止具5のスライド部8aを符号Bで示される矢印の方向とは逆に滑動して図2(a)に示される状態に復帰する。
Next, the chair provided with the standing assistance apparatus 1a is demonstrated using FIG.
FIGS. 2A and 2B are side views of a chair provided with the standing assistance device of the first embodiment. The same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted. In the following description, it is assumed that the chair 9a is installed and used on a substantially horizontal floor.
As shown in FIG. 2 (a), the chair 9a provided with the standing assistance device 1a includes a leg portion 12 including a caster 10 and a column 11, and a seat installed on the upper portion of the leg portion 12 through the standing assistance device 1a. It comprises a portion 13 and a backrest 15 attached to the seat portion 13 by a frame 14. A base plate plane 3 a is attached substantially horizontally to the upper end of the leg portion 12, and an upper plate plane 2 a is attached substantially horizontally to the lower surface of the seat portion 13. Therefore, in a normal use state, the seat portion 13 is substantially horizontal.
On the other hand, when the user sitting on the chair 9a leans forward and puts his weight on the front end of the seat 13 in the direction indicated by the direction C, the seat 13 is integrated with the top plate 2 and the shaft 6 Is tilted in the direction indicated by the direction A.
As the seat portion 13 tilts, the latching portion 4a of the latching means 4 slides in the direction indicated by the direction B on the upper surface of the slide portion 8a of the stopper 5, but eventually, as shown in FIG. It hooks on the protrusion 8 of the stopper 5. Thereby, tilting of the seat part 13 stops. After the user stands up, the latching portion 4a slides on the slide portion 8a of the fastener 5 in the direction opposite to the direction of the arrow B by the weight of the seat portion 13 and the backrest 15 as shown in FIG. ).

以上説明したように、本実施例の起立補助装置1aとそれを備えた椅子9aにおいては、座部13が前方を低くして後方を高くするように傾斜するため、利用者の起立動作が補助される。また、利用者の体重移動によって座部13が容易に傾斜し、その傾斜角度は利用者の体重移動によって調節できるため、操作性が良い。さらに、座部13が所望の角度以上傾斜しないため、利用者が誤って椅子9aから落ちる危険性が低い。そして、軽量構造であるため、持ち運びや収納が容易である。また、簡単な構造であり、既存の椅子に対しても容易に取り付けることができるため、製造コストを安くすることが可能である。   As described above, in the standing assist device 1a of this embodiment and the chair 9a including the standing assist device 1a, the seat 13 is inclined so as to lower the front and raise the rear, so that the user's standing motion is assisted. Is done. Further, the seat 13 is easily tilted by the user's weight shift, and the tilt angle can be adjusted by the user's weight shift, so that the operability is good. Furthermore, since the seat part 13 does not incline more than a desired angle, there is a low risk that the user will accidentally fall off the chair 9a. And since it is a lightweight structure, carrying and storing are easy. Moreover, since it is a simple structure and can be easily attached to an existing chair, the manufacturing cost can be reduced.

本実施例では、掛止手段4及び軸6を中実構造としているが、中空構造としても良い。また、掛止手段4と止具5の個数は1個に限らず、2個以上としても良い。さらに、上面板2が開いた後に基底板3となす角度の最大値が所望の値となるように、掛止部4aと突出部8との掛止位置は適宜調整することが望ましい。
また、切欠部7を浅く形成する、あるいは切欠部7そのものを設けないようにすることによって、利用者が着座している状態で上面板2と基底板3とが5〜15度の範囲内の角度をなすようにしても良い。この場合、利用者は着座している状態で座部13が予め前方に傾斜しているため、体重移動による座部13の傾動をより容易に行うことができる。なお、上記角度が5度よりも小さい場合には、上述の座部13の傾動を容易にする効果が小さく、上記角度が15度より大きい場合には、着座している状態の利用者が常に傾斜を感じて不安になったり、あるいは着座中に徐々に座部13からずれ落ちるなどのおそれがある。
さらに、止具5を基底板上面3aに設置する際に、基底板3の後端から止具5の一部を突出させないようにしても良い。この場合、基底板3によって止具5の強度が高められるため、利用者の体重が掛止手段4を介してスライド部8aに加えられた場合でも、止具5は変形することがない。
In this embodiment, the latching means 4 and the shaft 6 have a solid structure, but may have a hollow structure. Further, the number of the hooking means 4 and the stoppers 5 is not limited to one and may be two or more. Furthermore, it is desirable to appropriately adjust the latching position of the latching portion 4a and the protruding portion 8 so that the maximum value of the angle formed with the base plate 3 after the upper surface plate 2 is opened becomes a desired value.
Further, by forming the notch portion 7 shallowly or not providing the notch portion 7 itself, the upper surface plate 2 and the base plate 3 are within a range of 5 to 15 degrees while the user is seated. You may make it make an angle. In this case, since the seat portion 13 is inclined forward in advance while the user is seated, the seat portion 13 can be tilted more easily due to weight shift. When the angle is smaller than 5 degrees, the effect of facilitating the tilting of the seat portion 13 is small. When the angle is larger than 15 degrees, the seated user is always present. There is a risk that the user may feel an inclination and become uneasy or may gradually fall off the seat 13 while sitting.
Further, when the stopper 5 is installed on the base plate upper surface 3 a, a part of the stopper 5 may not be protruded from the rear end of the base plate 3. In this case, since the strength of the stopper 5 is increased by the base plate 3, the stopper 5 is not deformed even when the weight of the user is applied to the slide portion 8 a via the latching means 4.

実施例2について図3を用いて説明する(特に請求項4に対応)。
図3(a)は本発明の実施の形態に係る起立補助装置の実施例2の斜視図であり、(b)は突起部の拡大図であり、(c)は実施例2の起立補助装置を備えた椅子の側面図である。なお、図1及び図2の構成要素と同じものについては、同一の符号を付してその説明を省略する。
図3(a)に示すように、本実施例の起立補助装置1bは、実施例1の起立補助装置1aにおいて、掛止手段4の掛止部4aにレバー16が延設され、止具5に傾斜面17aと凹状の立面17bを有する突起部17が設けられた構造となっている。また、基底板側面3bには、レバー16と干渉しないように切欠部7aが設けられている。
上面板2の傾動に伴う掛止手段4の移動状態について図3(b)を用いて詳細に説明する。なお、突起部17の両側に位置する掛止手段4を区別するため、それぞれ掛止手段4x及び掛止手段4yと表すものとする。上面板2を開く方向に傾動させた場合、図3(b)に示すように、掛止手段4xは全体として方向Bで示す向きに引っ張られる。これにより、掛止手段4xはその掛止部4aを傾斜面17aに当接させながら方向Dで示す向きに摺動して容易に乗り越えることができる。そして、突起部17を乗り越えて掛止手段4yの状態となる。
これに対し、上面板2を閉じる方向に傾動させようとすると、掛止手段4yには方向Bと逆向きの力が加わる。しかし、掛止手段4yは掛止部4aが立面17bに係合し、方向Bと逆の向きには移動できないため、上面板2の閉じる方向への傾動が阻止される。すなわち、突起部17は上面板2の位置を保持する保持手段として作用する。
なお、レバー16を方向Eで示す向きに引き上げると、凹面17bに対して掛止手段4yの掛止部4aを係合させないようにすることができる。これにより、突起部17による保持動作を解除して、上面板2を閉じる方向に傾動させることが可能となる。
図3(c)に示すように、起立補助装置1bを備えた椅子9bは、脚部12と座部13の間に起立補助装置1bが介装された構造となっている。通常の使用状態では、座部13は略水平であるが、椅子9bに座った利用者が前傾姿勢になって座部13の前端に方向Cで示す向きに体重をかけると、座部13は上面板2と一体となって軸6を中心として方向Aで示す向きに傾動する。
座部13の傾動に伴い、掛止手段4の下端部は突起部17を順次乗り越えて、掛止手段4は全体として方向Bで示す向きに移動する。しかし、掛止手段4は掛止部4aが突起部17の立面17bと係合する場合には、方向Bと逆の向きには移動できない構造となっている。
このような構造の起立補助装置1bを備えた椅子9bにおいては、傾動後の座部13の傾斜状態が数段階に分けて保持されるという作用を有する。
Example 2 will be described with reference to FIG. 3 (corresponding to claim 4 in particular).
3A is a perspective view of Example 2 of the stand-up assisting apparatus according to the embodiment of the present invention, FIG. 3B is an enlarged view of the protrusion, and FIG. 3C is the stand-up assisting apparatus of Example 2.

As shown in FIG. 3A, in the standing assistance device 1b according to the present embodiment, a lever 16 extends from the latching portion 4a of the latching means 4 in the standing assistance device 1a according to the first embodiment. The projection portion 17 having the inclined surface 17a and the concave standing surface 17b is provided. The base plate side surface 3b is provided with a notch 7a so as not to interfere with the lever 16.
The movement state of the latching means 4 accompanying the tilting of the upper surface plate 2 will be described in detail with reference to FIG. In addition, in order to distinguish the latching means 4 located in the both sides of the projection part 17, it shall represent as the latching means 4x and the latching means 4y, respectively. When the top plate 2 is tilted in the opening direction, the latching means 4x is pulled in the direction indicated by the direction B as a whole, as shown in FIG. Thereby, the latching means 4x can easily get over by sliding in the direction indicated by the direction D while the latching portion 4a is in contact with the inclined surface 17a. And it gets over the projection part 17 and will be in the state of the latching means 4y.
On the other hand, when the upper plate 2 is tilted in the closing direction, a force opposite to the direction B is applied to the hooking means 4y. However, in the latching means 4y, the latching portion 4a is engaged with the upright surface 17b and cannot move in the direction opposite to the direction B, so that the top plate 2 is prevented from tilting in the closing direction. That is, the protrusion 17 acts as a holding unit that holds the position of the top plate 2.
When the lever 16 is pulled up in the direction indicated by the direction E, the latching portion 4a of the latching means 4y can be prevented from being engaged with the concave surface 17b. Thereby, it is possible to release the holding operation by the protrusion 17 and to tilt the top plate 2 in the closing direction.
As shown in FIG. 3C, the chair 9 b provided with the standing assistance device 1 b has a structure in which the standing assistance device 1 b is interposed between the leg portion 12 and the seat portion 13. In a normal use state, the seat portion 13 is substantially horizontal. However, when the user sitting on the chair 9b takes a forward leaning posture and puts his / her weight in the direction indicated by the direction C on the front end of the seat portion 13, the seat portion 13 is placed. Is tilted integrally with the top plate 2 in the direction indicated by the direction A about the shaft 6.
As the seat portion 13 is tilted, the lower end portion of the latching means 4 sequentially passes over the protrusions 17 and the latching means 4 moves as a whole in the direction indicated by the direction B. However, the latching means 4 has a structure that cannot move in the direction opposite to the direction B when the latching portion 4a is engaged with the vertical surface 17b of the projection portion 17.
In the chair 9b provided with the standing assist device 1b having such a structure, the tilted state of the seat 13 after tilting has an action of being held in several stages.

In the unlikely event that the user cannot stand up and puts weight on the seat again, it is safe. Moreover, since the seat part 13 can be inclined little by little in steps, even a powerless user can easily operate it.

なお、突起部17の個数は2個に限定されるものではなく、適宜変更可能である。また、掛止手段4の下端部と係合する突起部17の立面17bの形状は、凹状に限定されるものではなく、掛止手段4の掛止部4aの摺動を抑制する形状であれば良く、例えば、摩擦が大きくなるように微小な凹凸を形成した面や鉤状に形成した面としても良い。   The number of protrusions 17 is not limited to two, and can be changed as appropriate. Further, the shape of the rising surface 17b of the projection 17 that engages with the lower end portion of the latching means 4 is not limited to a concave shape, and is a shape that suppresses the sliding of the latching part 4a of the latching means 4. For example, it may be a surface formed with minute irregularities so as to increase friction or a surface formed in a bowl shape.
