Description

本願発明は、手摺装置に関し、さらに詳しくは展開・収納可能な椅子を備えた椅子付き手摺装置に関するものである。   The present invention relates to a handrail device, and more particularly, to a handrail device with a chair provided with a chair that can be expanded and stored.

手摺は、歩行時に手摺を掴むことで身体を安定させて安全且つ容易に歩行できるように補助することを主たる目的とするが、これに止まらず、例えば、人が立った姿勢から腰を下ろすときとか、腰を下ろした姿勢から立ち上がるときに、手摺を掴んでこれに体重の一部を預けることで腰に掛かる負担を軽減させることも目的の一つとしている。   The main purpose of the handrail is to stabilize the body by grabbing the handrail while walking and to help it walk safely and easily, but this does not stop, for example, when a person sits down from a standing posture One of the purposes is to reduce the burden on the waist by grabbing a handrail and depositing a part of the weight when standing up from a posture where the waist is lowered.

このような手摺の使用態様に鑑みれば、単に手摺を備えるのみではなく、該手摺に椅子が付設されていれば、歩行時あるいは腰の上げ下げ時に、例え一時的にであっても椅子に腰掛けて休むことができれば、進退疲労の軽減という点において有効であり、特に手すりを使用する者が高齢者等の身体的弱者である場合には、その効果は極めて顕著なものと考えられる。このような観点から、椅子付きの手摺が提案されている（特許文献１参照）。   In view of the manner of use of such handrails, it is not only provided with handrails, but if a handrail is attached to the handrail, it is possible to sit on the chair even when walking, or when raising and lowering the waist. If it is possible to take a rest, it is effective in reducing advancing and retreating fatigue, and the effect is considered to be extremely remarkable particularly when the person using the handrail is a physically weak person such as an elderly person. From such a viewpoint, a handrail with a chair has been proposed (see Patent Document 1).

特許文献１に記載された椅子付き手摺は、屋内において、土間から框に上がる場合とか、框側から土間側へ下りる場合等の段差の有る場所での移動を補助することを主目的とするものであって、段差部分の異動に際して、その手摺部分を掴んで身体の移動を補助させるという手摺本来の目的に沿った使用態様の他に、例えば、土間から框に上がるときに、先ず椅子に腰掛けて体を安定させ、しかる後、手摺部分を掴んで体を引き上げることで框側での立ち上がり動作を容易にするとか、逆に框側から土間に下りるときに、先ず框側において椅子に腰掛けて体を安定させ、しかる後、手摺部分を掴んで体重を手摺側に預けながら体を移動させることで土間側での立ち上がりを容易にせんとするものである。   The main purpose of the handrail with a chair described in Patent Document 1 is to assist movement in a place where there is a step, such as when going up from the dirt to the fence or when going down from the fence to the dirt side. However, when the step portion is changed, in addition to the usage mode in accordance with the original purpose of the handrail to assist the movement of the body by grasping the handrail portion, for example, when going up from the dirt to the heel, first sit on the chair Stabilize the body and then lift the body by grabbing the handrail part to make it easier to stand up on the heel side, or conversely when sitting down from the heel side to the soil, first sit on the chair on the heel side Stabilize the body and then move the body while grabbing the handrail part and depositing the weight on the handrail side, so that it is easy to get up on the dirt side.

特開２００６−３０５２１０号公報JP 2006-305210 A

ところで、上掲の特許文献１に記載された椅子付き手摺は、土間に設置した左右一対の支柱と該一対の支柱の上端間に跨る手摺笠木でなる手摺部分と、該左右一対の支柱の中段部に取付けられた座面で構成されるとともに、該座面の先端側には支持脚が備えられている。そして、座面の非使用時には、座面側に上記支持脚を折り畳んだ状態でこれを上記支柱側へ収納する一方、座面の使用時には、収納状態にある座面を上記支持脚と一体に前方側へ回動降下させ、該座面が略水平となった時点で該座面側から振り出された上記支持脚の先端を土間に接地させ、該支持脚によって座面に座った人の体重を支えるようにしている。   By the way, the handrail with a chair described in the above-mentioned Patent Document 1 includes a pair of left and right columns installed between soils, a handrail portion made of handrails straddling between the upper ends of the pair of columns, and a middle stage of the pair of left and right columns. It comprises a seat surface attached to the part, and a support leg is provided on the tip side of the seat surface. When the seat surface is not used, the support leg is folded into the seat surface side and stored in the support column side.When the seat surface is used, the seat surface in the stored state is integrated with the support leg. The front end of the support leg swung out from the seat surface side is grounded between the earth when the seat surface is substantially horizontal when the seat surface becomes substantially horizontal, and the person sitting on the seat surface by the support leg I try to support my weight.

このため、座面の使用に際しては、上記支持脚の接地操作が必要であって、その取扱が煩雑であり、特に使用者が高齢者等の身体的弱者であるような場合には、その接地操作が難しく、使用勝手が悪いという問題があった。また、座面の他に支持脚が備えられた構成であることから、その構造が複雑化するとともに、製造コストが高くつくという問題もあった。さらに、座面の振り出し状態においてはその前端側において上記支持脚が立設した状態となっていることから、手摺の近くを人が通る場合に、この支持脚に足を引っ掛けるということも考えられ、使用上の安全性の確保という点において好ましくない。   For this reason, when using the seating surface, it is necessary to perform the grounding operation of the support leg, and the handling is complicated, especially when the user is a physically weak person such as an elderly person. There was a problem that operation was difficult and usage was bad. In addition, since the supporting leg is provided in addition to the seating surface, the structure is complicated and the manufacturing cost is high. Furthermore, in the swinging state of the seating surface, since the support leg is standing on the front end side, when a person passes near the handrail, it is conceivable that the leg is caught on the support leg. This is not preferable in terms of ensuring safety in use.

一方、特許文献１に記載された椅子付き手摺は、座面を支柱側へ収納した状態においては、上記一対の支柱の内面と上記座面の側部が近接した構成となっていることから、上記座面を振り出し状態から支柱側へ収納するとき、支柱の内面と座面の側部の間に指先等が挟まれる恐れがあり、操作の安全性の確保という点において問題となり、特に目視での状態確認が困難な視覚障害者とか、動作が緩慢で且つ注意力も散漫になり易い高齢者等の操作に際しては、上記問題は看過できないものとなる。   On the other hand, the handrail with a chair described in Patent Document 1 has a configuration in which the inner surface of the pair of support columns and the side portion of the seat surface are close to each other in a state where the seat surface is stored on the support column side. When the seating surface is stowed from the swing-out state to the support column side, there is a risk that a fingertip or the like may be caught between the inner surface of the support column and the side of the seating surface, which is problematic in terms of ensuring the safety of operation, The above problems cannot be overlooked when operating visually impaired persons who are difficult to check their status, or elderly persons whose movements are slow and their attention tends to be distracted.

そこで本願発明は、操作が簡単で且つ使用上の安全性の高い椅子付き手摺装置を提供することを目的としてなされたものである。   Accordingly, the present invention has been made for the purpose of providing a handrail device with a chair that is easy to operate and highly safe in use.

That is, in the present invention, the storage posture of the chair body 2 is tilted rearward with respect to the surface through which the chair body 2 passes through the axis of the pair of column portions 11 and 11 of the handrail body 1 and the rotation. Since the rearward tilt of the support portion 3 is restricted, the chair body 2 may be inadvertently rotated from the stored position to the deployed position in the state where the chair body 2 is set to the stored position. It is blocked as much as possible, and further improvement in safety in use can be expected.

（ｅ）本願の第５の発明に係る椅子付き手摺装置によれば、上記（ｂ）に記載の効果に加えて、以下のような特有の効果が得られる。即ち、この発明では、上記回転支持部３に、該回転支持部３の軸方向に作用する付勢力を受けて、上記手摺体１と上記椅子体２の相対回動方向に摩擦抵抗を発生する制動部４０を備えているが、この制動部４０による制動作用は上記椅子体２が展開姿勢と収納姿勢の間で相対回動する場合における回動範囲の全域において一定に維持されることから、例えば、上記椅子体２の姿勢変更に伴う回動操作に際して該椅子体２に対する操作力をどの時点で解除しても（即ち、どの時点で椅子体２から手を離しても）該椅子体２はその位置で位置保持され、これによって操作上における安全性が更に向上することになる。   (E) According to the handrail device with chair according to the fifth invention of the present application, in addition to the effect described in (b) above, the following specific effect is obtained. That is, in the present invention, the rotational support portion 3 receives a biasing force acting in the axial direction of the rotational support portion 3 to generate a frictional resistance in the relative rotational direction of the handrail body 1 and the chair body 2. Although provided with a braking portion 40, the braking action by the braking portion 40 is maintained constant over the entire rotation range when the chair body 2 is relatively rotated between the deployed posture and the retracted posture. For example, the chair body 2 can be released at any point in time when the operation force applied to the chair body 2 is released during the rotation operation associated with the posture change of the chair body 2 (that is, at any point when the hand is released from the chair body 2). Is held in that position, which further improves operational safety.

このように構成された上記椅子体２は、上記一対の側フレーム部２１ａ，２１ａの端部にそれぞれ取り付けられた後述の回転支持部３，３を介して、上記手摺体１の左右一対の支柱部１１，１１の中段部に取り付けられ、該回転支持部３，３の枢支機能によって、図１に示すように上記椅子体２が上記手摺体１からその前方側へ延出した展開姿勢と、図２に示すように上記椅子体２が上方に跳ね上げられて上記手摺体１の左右の支柱部１１，１１の間を通ってその上部（即ち、上記椅子体２の前端部）が該支柱部１１、１１よりも僅かに後方側へ傾倒した収納姿勢に択一的に位置設定される。   The chair body 2 configured in this manner is provided with a pair of left and right columns of the handrail body 1 through rotation support portions 3 and 3 which will be described later attached to the ends of the pair of side frame portions 21a and 21a. 1 and 11, the chair body 2 is extended from the handrail body 1 to the front side thereof as shown in FIG. 2, the chair body 2 is flipped upward and passes between the left and right support pillars 11, 11 of the handrail body 1 so that the upper portion thereof (that is, the front end portion of the chair body 2) is The position is alternatively set to the storage posture tilted slightly rearward from the support columns 11 and 11.

また、図２に示すように上記椅子体２が収納姿勢に設定された状態においては、図３に示すように、上記手摺体１の各支柱部１１及び手摺部１２の内面と上記椅子体２の椅子フレーム２１の外面との間に、少なくとも手の甲が進入し得るような間隔をもつ隙間６が形成されるように、上記手摺体１と上記椅子体２の形状が相対的に設定されている。   In the state where the chair body 2 is set to the storage posture as shown in FIG. 2, as shown in FIG. 3, the inner surfaces of the column portions 11 and the handrail portion 12 of the handrail body 1 and the chair body 2. The shape of the handrail body 1 and the chair body 2 is relatively set so that a gap 6 is formed between the outer surface of the chair frame 21 and a space 6 at which at least the back of the hand can enter. .

「回転支持部３」
上記回転支持部３は、上述のように、上記手摺体１に対して上記椅子体２を上下方向に回動自在に枢支することを主たる機能（即ち、枢支機能）とするものであるが、係る枢支機能の他に、上記椅子体２の回動範囲の規制機能と、上記椅子体２の展開姿勢での回動規制機能（荷重支持機能）と、上記椅子体２の回動動作に所定の制動力を付与する制動力付与機能を併せもつものである。 "Rotating support 3"
As described above, the rotation support portion 3 has a main function (that is, a pivot function) for pivotally supporting the chair body 2 so as to be rotatable in the vertical direction with respect to the handrail body 1. However, in addition to the pivot function, the function of restricting the rotation range of the chair body 2, the function of restricting the rotation of the chair body 2 in the deployed posture (load support function), and the rotation of the chair body 2 It also has a braking force applying function for applying a predetermined braking force to the operation.

即ち、上記回転支持部３は、図４〜図６に示すように、次述の固定軸体３１と回転軸体３２及びブッシュ３３を備えている。   That is, as shown in FIGS. 4 to 6, the rotation support portion 3 includes a fixed shaft body 31, a rotation shaft body 32, and a bush 33 described below.

上記固定軸体３１は、図４及び図５に示すように、取付軸部３９を介して上記手摺体１の支柱部１１に固定されるものであって、鍔部３１ａと軸部３１ｂからなる異形軸体とされる。また、上記軸部３１ｂは、図６（イ）、（ロ）に示すように、その周方向の一部を小径部４１とし、他の一部を大径部４２とした構成とされ、且つこの小径部４１と大径部４２の間の段差部は軸方向に延びる係合面４３，４４とされている。   As shown in FIGS. 4 and 5, the fixed shaft body 31 is fixed to the support column portion 11 of the handrail body 1 through an attachment shaft portion 39, and includes a collar portion 31 a and a shaft portion 31 b. It is a deformed shaft. Further, as shown in FIGS. 6A and 6B, the shaft portion 31b has a configuration in which a part in the circumferential direction is a small diameter part 41 and the other part is a large diameter part 42, and Step portions between the small diameter portion 41 and the large diameter portion 42 are engaging surfaces 43 and 44 extending in the axial direction.

上記回転軸体３２は、図４及び図５に示すように、軸穴５１を備えた穴付き軸体で構成される。上記軸穴５１は、図６（イ）、（ロ）に示すように、その周方向の一部を大径穴５２とし、他の一部を小径穴５３とした構成とされ、且つこの大径穴５２と小径穴５３の間の段差部は軸方向に延びる係合面５４、５５とされている。   As shown in FIGS. 4 and 5, the rotary shaft body 32 is configured by a shaft body with a hole provided with a shaft hole 51. As shown in FIGS. 6 (a) and 6 (b), the shaft hole 51 has a configuration in which a part in the circumferential direction is a large diameter hole 52 and the other part is a small diameter hole 53. Step portions between the diameter hole 52 and the small diameter hole 53 are engaging surfaces 54 and 55 extending in the axial direction.

そして、図５に示すように、上記固定軸体３１の軸部３１ｂ部分は上記回転軸体３２の軸穴５１内に嵌入される。この嵌入状態においては、図６（イ）、（ロ）に示すように、上記固定軸体３１の上記軸部３１ｂに設けられた上記大径部４２が、上記回転軸体３２の軸穴５１に設けられた上記大径穴５２内に位置している。この場合、上記大径穴５２の周方向長さが上記大径部４２の周方向長さよりもの長くなるようにこれら両者の寸法が相対的に設定されているので、上記固定軸体３１に対して上記回転軸体３２は、図６（イ）に示すように該回転軸体３２側の係合面５５が上記固定軸体３１側の係合面４４に係合して該回転軸体３２がそれ以上に矢印ｂ方向へ回動するのが規制された位置と、図６（ロ）に示すように該回転軸体３２側の係合面５４が上記固定軸体３１側の係合面４３に係合して該回転軸体３２がそれ以上に矢印ａ方向へ回動するのが規制された位置との間で相対回動し得るようになっている。   As shown in FIG. 5, the shaft portion 31 b portion of the fixed shaft body 31 is fitted into the shaft hole 51 of the rotating shaft body 32. In this inserted state, as shown in FIGS. 6A and 6B, the large diameter portion 42 provided in the shaft portion 31 b of the fixed shaft body 31 is connected to the shaft hole 51 of the rotating shaft body 32. It is located in the large-diameter hole 52 provided in. In this case, since the dimension of both of these is set relatively so that the circumferential direction length of the said large diameter hole 52 may become longer than the circumferential direction length of the said large diameter part 42, with respect to the said fixed shaft 31 As shown in FIG. 6 (a), the rotary shaft body 32 has an engaging surface 55 on the rotating shaft body 32 side engaged with an engaging surface 44 on the fixed shaft body 31 side. And the engagement surface 54 on the rotating shaft 32 side is the engagement surface on the fixed shaft 31 side as shown in FIG. The rotary shaft body 32 can be rotated relative to the position where the rotation shaft body 32 is restricted from further rotating in the direction of the arrow a.

また、上述のように、上記回転支持部３の上記固定軸体３１は上記手摺体１の支柱部１１に固定され、上記回転軸体３２は上記椅子体２の椅子フレーム２１に固定されていることから、上記回転軸体３２が上記固定軸体３１に対して相対回動することで、上記椅子体２は上記回転支持部３を中心として上記手摺体１に対して上下方向に相対回動することになる。   Further, as described above, the fixed shaft body 31 of the rotation support portion 3 is fixed to the support column portion 11 of the handrail body 1, and the rotation shaft body 32 is fixed to the chair frame 21 of the chair body 2. Therefore, when the rotary shaft 32 rotates relative to the fixed shaft 31, the chair 2 rotates relative to the handrail 1 in the vertical direction around the rotation support 3. Will do.

そして、図６（イ）に示す上記回転軸体３２の回動位置では、上記椅子体２は図１に示すように上記手摺体１から前方へ跳ね出した展開姿勢とされる。また、この展開姿勢では、上記椅子体２には人の着座によってその体重が掛かるが、この体重による上記回転軸体３２に作用する回転モーメントは、上記固定軸体３１の係合面４４と上記回転軸体３２の係合面５５の係合による回動規制作用を介して上記手摺体１によって支持され、従来のように上記回転軸体３２に支持脚を設ける必要はない。   And in the rotation position of the said rotating shaft body 32 shown to FIG. 6 (A), the said chair body 2 is made into the unfolding attitude | position which protruded ahead from the said handrail body 1 as shown in FIG. In this unfolded posture, the chair body 2 is weighted by the seating of a person, and the rotational moment acting on the rotating shaft body 32 due to the weight is caused by the engagement surface 44 of the fixed shaft body 31 and the It is supported by the handrail body 1 through the rotation restricting action by the engagement of the engaging surface 55 of the rotating shaft body 32, and there is no need to provide a supporting leg on the rotating shaft body 32 as in the prior art.

これに対して、図６（ロ）に示す上記回転軸体３２の回動位置では、上記椅子体２は図２に示すように上記手摺体１側に側手摺体１よりもやや後傾状態で収納された収納姿勢とされる。   On the other hand, in the rotation position of the rotary shaft body 32 shown in FIG. 6B, the chair body 2 is tilted slightly rearward from the side handrail body 1 on the handrail body 1 side as shown in FIG. The storage posture is stored in the storage position.

以上が上記回転支持部３の「枢支機能」と「回動範囲規制機能」及び「回動規制機能（荷重支持機能）」である。   The above is the “pivot support function”, “rotation range restriction function”, and “turn restriction function (load support function)” of the rotation support part 3.

一方、図５に示すように、上記回転軸体３２はカラー３５を介してその一方の端面が上記固定軸体３１の鍔部３１ａに当接される。また、上記回転軸体３２の他方の端面側には、一対の皿バネ３６，３６を介してブッシュ３３が配置され、しかもこのブッシュ３３はボルト３８によって上記固定軸体３１側に締結されている。   On the other hand, as shown in FIG. 5, one end surface of the rotary shaft body 32 is brought into contact with the flange portion 31 a of the fixed shaft body 31 via a collar 35. A bush 33 is disposed on the other end face side of the rotary shaft 32 via a pair of disc springs 36, 36, and the bush 33 is fastened to the fixed shaft 31 by a bolt 38. .

従って、上記皿バネ３６，３６の撓曲変形により生じた軸力によって上記回転軸体３２は上記カラー３５を介して上記固定軸体３１の鍔部３１ａに押圧付勢され、該固定軸体３１と回転軸体３２の接触部（即ち、上記カラー３５の一方の面と上記固定軸体３１の鍔部３１ａの面、及び上記カラー３５の他方の面と上記回転軸体３２の一方の端面）には、上記固定軸体３１と上記回転軸体３２の相対回転方向に摩擦力が発生し、これが上記固定軸体３１と回転軸体３２の相対回転に対して摩擦抵抗として作用する。   Therefore, the rotary shaft body 32 is pressed and urged to the flange portion 31a of the fixed shaft body 31 through the collar 35 by the axial force generated by the bending deformation of the disc springs 36, 36, and the fixed shaft body 31 is pressed. And the contact portion of the rotating shaft 32 (that is, one surface of the collar 35 and the surface of the flange 31a of the fixed shaft 31 and the other surface of the collar 35 and one end surface of the rotating shaft 32). Then, a frictional force is generated in the relative rotation direction of the fixed shaft body 31 and the rotary shaft body 32, and this acts as a frictional resistance against the relative rotation of the fixed shaft body 31 and the rotary shaft body 32.

しかも、この摩擦抵抗は、上記固定軸体３１と回転軸体３２の相対回転位置によって変化することなく常時一定に保持される。このため、上記皿バネ３６の撓曲変形量、即ち、上記ボルト３８の締め込み量を適宜調整して摩擦抵抗のように大きさを適正に設定することで、上記椅子体２を収納姿勢と展開姿勢の間で回動操作する場合に過大な操作抵抗を生じることなく容易に操作することができるとともに、上記椅子体２に対する回動操作力をその操作範囲のどの位置で解除しても上記椅子体２の姿勢をその位置で保持させることができることになる。これが上記回転支持部３の「制動力付与機能」であり、この実施形態では、上記固定軸体３１と回転軸体３２と上記皿バネ３６及びボルト３８によって特許請求の範囲中の「制動部４０」が構成される。   Moreover, this frictional resistance is always kept constant without changing depending on the relative rotational position of the fixed shaft body 31 and the rotating shaft body 32. For this reason, the chair body 2 is set in the stowed posture by appropriately adjusting the amount of bending deformation of the disc spring 36, that is, the amount of tightening of the bolt 38 and appropriately setting the size such as frictional resistance. When rotating between unfolded postures, it can be easily operated without causing excessive operating resistance, and the position of the rotating operation force on the chair body 2 can be released at any position within the operating range. The posture of the chair body 2 can be held at that position. This is the “braking force applying function” of the rotation support portion 3. In this embodiment, the “braking portion 40” in the claims is defined by the fixed shaft body 31, the rotation shaft body 32, the disc spring 36, and the bolt 38. Is configured.

以上のように、上記手摺体１に上記回転支持部３を介して上記椅子体２を展開・収納可能に取付けて構成される椅子付き手摺装置Ｚ１においては、以下のような作用効果が得られる。   As described above, in the handrail device with chair Z1 configured by attaching the chair body 2 to the handrail body 1 via the rotation support portion 3 so that the chair body 2 can be unfolded and stored, the following effects can be obtained. .

この実施形態の椅子付き手摺装置Ｚ１では、上記手摺体１の中段部に上記回転支持部３を介して上記椅子体２を上下方向に回動可能に取付けて構成され、上記椅子体２が展開姿勢に設定された状態では該椅子体２に人が着座することができ、また該椅子体２が収納姿勢に設定された状態では該椅子体２が上記手摺体１側に収納されるようにしているので、この椅子付き手摺装置Ｚ１の使用者は、
（イ）上記椅子体２を収納姿勢とした状態で、上記手摺体１の上記手摺部１２を掴んで歩行等の動作を容易且つ安全に行う本来的な機能である「手摺機能」と、
（ロ）上記椅子体２を展開姿勢として使用者の着座に供する「椅子機能」と、
（ハ）上記椅子体２を展開姿勢とした状態で該椅子体２に着座した使用者が上記手摺部１２を掴んで自己の姿勢変更を補助する「手摺・椅子複合機能」を、
必要に応じて選択することができ、椅子付き手摺装置Ｚ１の使用価値の多様化が図れるとともに、使用者側における利便性も向上することになる。 In the handrail device with chair Z1 of this embodiment, the chair body 2 is attached to the middle part of the handrail body 1 via the rotation support part 3 so as to be rotatable in the vertical direction, and the chair body 2 is developed. A person can sit on the chair body 2 in the state set to the posture, and the chair body 2 is stored on the handrail body 1 side in the state where the chair body 2 is set to the storage position. Therefore, the user of this handrail device with chair Z1 is
(A) In the state where the chair body 2 is in the storage posture, the “handrail function” which is an original function for grasping the handrail portion 12 of the handrail body 1 and performing an operation such as walking easily and safely;
(B) “Chair function” for seating the user with the chair body 2 in the unfolded posture;
(C) A “handrail / chair combined function” in which a user sitting on the chair body 2 in the state where the chair body 2 is in the deployed posture grasps the handrail portion 12 and assists in changing his / her posture.
It can be selected as necessary, and the use value of the handrail device with chair Z1 can be diversified, and convenience on the user side is also improved.

この実施形態の椅子付き手摺装置Ｚ１では、上記手摺体１と上記椅子体２を、上記回転支持部３を介して回動可能としているが、この回転支持部３は、椅子体２が展開姿勢に設定され該椅子体２に人が着座してここに体重が掛かってもこれを支持することができる構成となっていることから、上記椅子体２を収納姿勢から展開姿勢に姿勢変更させる場合、単に上記椅子体２の回動操作のみを行えばよく、例えば、例えば、従来のように、座面の張出操作を行うとともに支持脚の接地操作を行う必要がある場合に比して、構造の簡略化、低コスト化及び操作性の向上が図れる。   In the handrail device with chair Z1 of this embodiment, the handrail body 1 and the chair body 2 can be rotated via the rotation support portion 3. The rotation support portion 3 is configured such that the chair body 2 is deployed. When the chair body 2 is changed from the stowed position to the deployed position, the chair body 2 can be supported even when a person is seated on the chair body 2 and the body weight is applied to the chair body 2. For example, as compared with the conventional case where it is necessary to perform the operation of extending the seating surface and the operation of grounding the support leg, for example, The structure can be simplified, the cost can be reduced, and the operability can be improved.

この実施形態の椅子付き手摺装置Ｚ１では、上記椅子体２を展開姿勢に設定した状態にあっては、該椅子体２の下方側には歩行の障害となるような部材は存在しないので、例えば、座面の下側に支持脚が立設状態で存在する場合のようにこの支持脚に歩行者が足を引っ掛けるという恐れが皆無であり、使用上の安全性がより一層促進され、特に使用者が歩行に支障がある高齢者等である場合には、その効果はより顕著なものとなる。   In the handrail device with chair Z1 of this embodiment, in the state where the chair body 2 is set in the unfolded posture, there is no member that hinders walking on the lower side of the chair body 2, for example, , There is no fear that pedestrians will be caught on this support leg as in the case where the support leg is standing upside down on the seating surface, and the safety in use is further promoted, especially in use When the person is an elderly person or the like who has difficulty in walking, the effect becomes more remarkable.

この実施形態の椅子付き手摺装置Ｚ１では、上記椅子体２が収納姿勢に設定された状態において、上記手摺体１の周縁に位置する上記一対の支柱部１１，１１及び手摺部１２と、上記椅子体２の上記椅子フレーム２１との間に、少なくとも人の手の甲が通過し得る大きさの隙間６が形成されるように、上記手摺体１と上記椅子体２の形状が相対的に設定されているので、上記椅子体２を展開姿勢から跳ね上げて収納姿勢に姿勢変更するような場合に、例え使用者が上記椅子体２の側部を持って操作を行ったような場合であっても、使用者の手が上記椅子体２の側部と上記手摺体１の間に挟まれるということが未然に且つ確実に防止され、使用に際しての操作上の安全性が確保される。   In the handrail device with chair Z1 of this embodiment, in the state where the chair body 2 is set in the storage position, the pair of column portions 11 and 11 and the handrail portion 12 positioned on the periphery of the handrail body 1, and the chair The shape of the handrail body 1 and the chair body 2 is relatively set so that a gap 6 having a size that allows at least the back of a human hand to pass through is formed between the chair frame 21 of the body 2. Therefore, when the chair body 2 is flipped up from the deployed position and changed to the stowed position, even if the user performs an operation while holding the side of the chair body 2, for example. In addition, it is possible to prevent the user's hand from being sandwiched between the side portion of the chair body 2 and the handrail body 1 in advance and to ensure operational safety during use.

この実施形態の椅子付き手摺装置Ｚ１では、上記椅子体２が収納姿勢に設定された状態においては、該椅子体２が上記手摺体１よりも後方側へ傾倒し且つ上記回転支持部３によってそれ以上の後傾が規制されるようになっているので、上記椅子体２が収納姿勢から展開姿勢側へ不用意に回動することが可及的に阻止され、使用上の安全性の更なる向上が期待できる。   In the handrail device with chair Z1 of this embodiment, in a state where the chair body 2 is set in the storage position, the chair body 2 is tilted rearward from the handrail body 1 and is rotated by the rotation support portion 3. Since the above rearward tilt is regulated, the chair body 2 is prevented from being inadvertently rotated from the stowed posture to the deployed posture side as much as possible, thereby further improving the safety in use. Improvement can be expected.

この実施形態の椅子付き手摺装置Ｚ１では、上記回転支持部３が、上記皿バネ３６の付勢力を受けて、上記手摺体１と上記椅子体２の相対回動方向に接触抵抗を発生するように構成されており、しかもその制動作用は上記椅子体２が展開姿勢と収納姿勢の間で姿勢変更される場合の回動範囲の全域において一定に維持されるものであることから、上記椅子体２の回動操作に際して該椅子体２に対する操作力をどの時点で解除しても（即ち、どの時点で椅子体２から手を離しても）該椅子体２はその位置で位置保持されるので、操作上の安全性が更に向上することになる。   In the handrail device with chair Z1 of this embodiment, the rotation support portion 3 receives a biasing force of the disc spring 36 and generates a contact resistance in the relative rotation direction of the handrail body 1 and the chair body 2. Further, the braking action is maintained constant over the entire rotation range when the chair body 2 is changed between the deployed posture and the stowed posture. 2. When the operating force on the chair body 2 is released at any time (ie, at any time the hand is released from the chair body 2), the chair body 2 is held in that position. Therefore, operational safety is further improved.
