Description

この発明は、主として、自立歩行等が困難な要介護者、要支援者、高齢者又は患者等（以下、単に要介護者等という。）の立ち上がり動作を補助する自立式手すりを有効活用できる補助具の技術分野に属し、さらにいえば、間隔をあけて設置された自立式手すり同士をフレキシブルに連絡することが可能な連結用手すり補助具および同補助具を用いた自立式手すりの連結構造に関する。
前記自立式手すりのバリエーションは種々あるが、ここでは特に、ベース板から立ち上がる支柱間（例えば、３０ｃｍ間隔）の上下方向に複数本の横桟を連結してなる構造で、床面はもとより玄関の上がり框に設置される立ち上がり動作補助用の手すりを指す。
ちなみに、前記立ち上がり動作補助用の手すりには、シングルタイプ（特許文献１参照）とダブルタイプ（本願の図１１参照）がある。 The present invention mainly provides assistance that can effectively use a self-supporting handrail that assists the standing-up motion of a care recipient, supporter, elderly person or patient (hereinafter simply referred to as a care recipient) who is difficult to walk independently. More specifically, the present invention relates to a handrail auxiliary tool for connection capable of flexibly connecting self-supporting handrails installed at intervals, and a connection structure of a self-supporting handrail using the auxiliary tool. .
There are various variations of the above-mentioned self-supporting handrail, but here, in particular, it is a structure in which a plurality of horizontal rails are connected in the vertical direction between the columns that stand up from the base plate (for example, at intervals of 30 cm). This refers to a handrail for assisting standing up that is installed on the rising fence.
Incidentally, there are a single type (see Patent Document 1) and a double type (see FIG. 11 of the present application) as the handrails for assisting the rising operation.

自立歩行等が困難な要介護者等には、車椅子等の座った姿勢から立ち上がる動作、又はベッドから降りて立ち上がる動作等を補助する補助具が必要である。そして、立ち上がった後はその立ち姿勢のまま目的の場所へ移動するための補助具も必要である。 A care recipient who is difficult to walk independently needs an assisting tool that assists the user to get up from a sitting posture such as a wheelchair or to get up from a bed. And after standing up, the auxiliary tool for moving to the target place with the standing posture is also required.

例えば、特許文献１には、段差などの高低差がないフロア上に間隔をあけて設置された２つ（一対）の立ち上がり動作補助具（自立式手すり）１、１を連結する横移動用手すり２が開示されている（段落［００１３］、図２等を参照）。
この横移動用手すり２によると、間隔をあけて隣り合う２つの立ち上がり動作補助具１、１を連結して一体化できることはもとより、手すり部を連続的に形成できる。
よって、要介護者等は、座った姿勢から立ち上がる動作を、立ち上がり動作補助具１の助けを借りて立ち上がることができる上に、立ち上がった姿勢になると、連続する横移動用手すり２の助けを借りて歩行することができる（段落［０００９］等を参照）。 For example, Patent Document 1 discloses a handrail for lateral movement that connects two (a pair of) standing-up motion assisting tools (self-supporting handrails) 1 and 1 that are spaced apart on a floor having no level difference such as a step. 2 is disclosed (see paragraph [0013], FIG. 2, etc.).
According to the handrail 2 for lateral movement, a handrail portion can be formed continuously as well as connecting and integrating two rising motion assisting tools 1 and 1 adjacent to each other with a gap therebetween.
Therefore, a care recipient or the like can get up from the sitting posture with the help of the stand-up motion assisting tool 1 and, when in the standing up posture, with the help of the continuous handrail 2 for lateral movement. (See paragraph [0009] etc.).

特開２０１０−２２０８５１号公報JP 2010-220851 A

しかしながら、特許文献１にかかる横移動用手すり２は、横方向長さ（横寸）を調整できる構造になっていないので、立ち上がり動作補助具１、１同士の連結作業を行う際には、一方の立ち上がり動作補助具１を移動させて、横移動用手摺り２の横寸にきっちり合わせる必要があった。この立ち上がり動作補助具は、要介護者等が体重を預けても転倒しない設計が要求される重量物（２０ｋｇ前後が主流）であり、介護者等は、この精緻な位置合わせ作業に難渋していた。
言い換えると、この問題は、立ち上がり動作補助具１、１の設置間隔に応じて、サイズ（横寸）の異なる複数の横移動用手摺りを用意（購入）する必要があり、不経済でもあった。
さらに、前記横移動用手すり２は、上下方向角度を調整できる構造にもなっていないので、段差などの高低差がある場所に設置された立ち上がり動作補助具１、１同士を、手すり部を連続的に形成するように連結することは一切できなかった。 However, since the handrail 2 for lateral movement according to Patent Document 1 does not have a structure in which the lateral length (horizontal dimension) can be adjusted, when connecting the rising motion assisting tools 1 and 1, It was necessary to move the rising motion assisting tool 1 and adjust it to the horizontal dimension of the handrail 2 for lateral movement. This stand-up motion assisting tool is a heavy object (mainly around 20 kg) that is required to be designed so that it does not fall over even if the care recipient needs to leave his / her weight, and the caregiver is having difficulty with this precise alignment work. It was.
In other words, this problem is uneconomical because it is necessary to prepare (purchase) a plurality of handrails for lateral movement having different sizes (horizontal dimensions) according to the installation intervals of the rising motion assisting tools 1 and 1. .
Further, since the handrail 2 for lateral movement is not structured so that the angle in the vertical direction can be adjusted, the standing motion assisting tools 1 and 1 installed in a place where there is a height difference such as a step are connected to the handrail portion continuously. It was not possible to connect them so as to form them.

例えば、本願の図１１は、玄関の上がり框部に設けたダブルタイプの自立式手すり１０、１１を示している。一方の自立式手すり１０は上がり框用であり、他方の自立式手すり１１は平置き用である。
玄関は、要介護者等（および介護者等）が通院等で出入りする際、最も注意を払う部位であるが、従来の連結用手すり補助具（横移動用手すり２）は、如何様にしても、自立式手すり１０、１１の手すり部を連続的に形成するように連結することはできず、よって、要介護者等の安全性が損なわれ、また介護者等に重労働を強いていた。 For example, FIG. 11 of the present application shows double-type self-supporting handrails 10 and 11 provided on the rising ridges of the entrance. One self-supporting handrail 10 is used for raising heels, and the other self-supporting handrail 11 is used for flat placement.
The entrance is the part that pays the most attention when care recipients etc. (and caregivers etc.) go out and go to the hospital etc., but how to use the conventional handrail aid for connecting (handrail 2 for lateral movement) However, the handrails of the self-supporting handrails 10 and 11 cannot be connected so as to be continuously formed. Therefore, the safety of care recipients is impaired, and the caregivers are forced to work hard.

このように、従来の連結用手すり補助具（横移動用手すり２）は、自在性（柔軟性）、作業性、汎用性、および経済性の点において種々の問題があり、解決すべき課題となっている。 As described above, the conventional handrail auxiliary tool for connection (handrail 2 for lateral movement) has various problems in terms of flexibility (flexibility), workability, versatility, and economy, and problems to be solved. It has become.

本発明に係る連結用手すり補助具および同補助具を用いて連結した自立式手すりの連結構造によれば、以下の効果を奏する。
（１）本発明にかかる連結用手すり補助具によれば、手すり部が伸縮可能な構成を備え、かつ手すり部を上下方向に回動可能で、水平方向にも回動可能な機構を備えているので、間隔をあけて設置された自立式手すり同士をフレキシブルに連結できる。
すなわち、連結用手すり補助具は所謂３次元的な挙動を実現できるので、連結対象物たる２つの自立式手すりの配置を所定の部位にきっちり位置決めしておく必要はなく、ラフな設置態様でも誤差（位置ずれ）を吸収し、良好な連結構造を実現することができる。
言い換えると、ユーザー側が希望する自立式手すりの設置態様に可能な限り対応できる連結用手すり補助具を提供できる。例えば、段差などの高低差がある場所にそれぞれ設置した自立式手すりであっても、上下方向の角度を自在に可変する等してフレキシブルな連結構造を実現できる。
したがって、１本の連結用手すり補助具で、多様な連結バリエーションを実現できるので、自在性（柔軟性）、作業性、汎用性、および経済性に優れた連結用手すり補助具および同補助具を用いて連結した自立式手すりの連結構造を実現できる。
（２）請求項４記載の連結用手すり補助具によれば、上記効果に加え、補助具自体の強度・剛性を高めることはもとより、連結構造全体の強度・剛性を高めることができ、より安定性を増した連結構造を実現することができる。また、手すり部を上下２段に設けたことにより、要介護者等が手すり部を掴むバリエーションが増大し、より良好な歩行（掴まり歩き）を実現することができる。 According to the connecting handrail assisting device and the connecting structure of the self-supporting handrail connected using the assisting device according to the present invention, the following effects can be obtained.
(1) According to the handrail auxiliary tool for connection according to the present invention, the handrail portion has a configuration that can be expanded and contracted, and the handrail portion can be rotated in the vertical direction, and can be rotated in the horizontal direction. Therefore, it is possible to flexibly connect the self-supporting handrails installed at intervals.
That is, since the handrail assisting tool for connection can realize a so-called three-dimensional behavior, it is not necessary to position the two self-supporting handrails that are the objects to be connected exactly at a predetermined portion, and errors can occur even in rough installation modes. (Position shift) can be absorbed and a good connection structure can be realized.
In other words, it is possible to provide a handrail auxiliary tool for connection that can correspond as much as possible to the installation mode of the self-supporting handrail desired by the user. For example, even in the case of a self-supporting handrail installed in a place with a difference in height such as a step, a flexible connection structure can be realized by freely changing the angle in the vertical direction.
Therefore, since a variety of connection variations can be realized with a single handrail auxiliary tool for connection, the handrail auxiliary tool for connection and the auxiliary tool with excellent flexibility (flexibility), workability, versatility, and economy are provided. It is possible to realize a connection structure of self-supporting handrails connected by using.

以下、本発明に係る連結用手すり補助具および同補助具を用いた自立式手すりの連結構造の実施例を図面に基づいて説明する。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a handrail assisting tool for connection according to the present invention and a connection structure of a self-supporting handrail using the assisting tool will be described with reference to the drawings.

図１は、前記連結用手すり補助具１を用いて連結した自立式手すり１０、１１の連結構造を示している。
前記連結用手すり補助具１は、図２、図３にも示したように、間隔をあけて設置された自立式手すり同士１０、１１の間を連絡する伸縮可能な手すり部２と、前記手すり部２を、前記自立式手すり１０、１１を構成する支柱１０ａ、１１ａに対し上下方向および水平方向に回動可能に保持する保持機構３とからなり、当該支柱１０ａ、１１ａ間に連結される構成である。
ちなみに、図示例にかかる連結用手すり補助具１は、段差などの高低差がある部位、具体的には上がり框部に設置した上がり框用の自立式手すり１０と、平置き用の自立式手すり１１とを連結する態様で実施している。図中の符号１２はベース板であり、符号１３は補助台（ステップ台）である。 FIG. 1 shows a connecting structure of self-supporting handrails 10 and 11 connected using the connecting handrail assisting tool 1.
As shown in FIGS. 2 and 3, the connecting handrail assisting tool 1 includes an extendable handrail portion 2 that communicates between the self-supporting handrails 10 and 11 that are installed at intervals, and the handrail. The structure which consists of the holding mechanism 3 which hold | maintains the part 2 so that rotation to an up-down direction and a horizontal direction with respect to the support | pillars 10a and 11a which comprise the said self-supporting handrail 10 and 11 is connected between the said support | pillars 10a and 11a. It is.
Incidentally, the handrail assisting tool 1 for connection according to the illustrated example includes a self-supporting handrail 10 for a rising saddle installed on a part having a level difference such as a step, specifically a rising saddle, and a self-supporting handrail 11 for flat placement. Are implemented in a manner to connect them. Reference numeral 12 in the figure denotes a base plate, and reference numeral 13 denotes an auxiliary base (step base).

要するに、本発明にかかる連結用手すり補助具１は、前記手すり部２が伸縮可能な構成を備え、かつ手すり部２を上下方向に回動可能で、水平方向にも回動可能な機構を備えていることを大きな特徴としている。以下、この点について具体的に説明する。 In short, the handrail auxiliary tool 1 for connection according to the present invention has a structure in which the handrail portion 2 can be expanded and contracted, and a mechanism that can turn the handrail portion 2 in the vertical direction and also in the horizontal direction. It is a great feature. Hereinafter, this point will be specifically described.

（手すり部２が伸縮可能な構成であることの説明）
前記手すり部２は、太管２ａと、この太管２ａ内の中心軸方向に摺動可能な細管２ｂとを嵌め合わせて伸縮可能な構成としている。具体的には、太管２ａ（φ３２ｍｍ）の両端部内へそれぞれ嵌め合わせた２本（例えば一対）の細管（φ２８ｍｍ）２ｂ、２ｂが伸縮する構成で実施している。もちろん、１本の太管２ａに対して１本の細管２ｂを伸縮可能な構成で実施することもできる（図示略）。 (Explanation that the handrail portion 2 has an extendable structure)
The handrail portion 2 is configured to be able to expand and contract by fitting a thick tube 2a and a thin tube 2b slidable in the central axis direction in the thick tube 2a. Specifically, two thin tubes (φ28 mm) 2b and 2b (for example, a pair) fitted into both ends of the thick tube 2a (φ32 mm) are expanded and contracted. Of course, one thin tube 2b can be expanded and contracted with respect to one thick tube 2a (not shown).

ここでいう伸縮可能な構成とは、図２（Ｂ）、（Ｃ）に例示したように、太管２ａに対して細管２ｂ、２ｂを摺動させて任意の位置で簡易に位置決め固定できる構成（クイックロック機構）をいう。
このクイックロック機構には種々のバリエーションがあるが、本実施例では、一例として、図４に示したように、所謂フレアレス管継手（くい込み継手）の要領で実施している。すなわち、太管２ａの端部のねじ山にねじ込まれる締付ナット４に、各々の端部が各先端へ向かって漸次縮径する縮径部を備えたスリーブ５が内接しており、太管２ａのねじ山に徐々に該締付ナット４をねじ込むことで、細管２ｂが挿通したスリーブ５の両端部が圧迫され、これにより該スリーブ５がすぼまって細管２ｂを徐々に挟圧して固定する構成で実施している。
なお、前記スリーブ５は、すぼまり易くするために円周の一部をカットした有端リングが好適に用いられる。また、前記太管２ａと細管２ｂの径（φ）は前記寸法に限定されず、適宜設計変更可能である。 The structure which can be expanded and contracted here is a structure which can be easily positioned and fixed at an arbitrary position by sliding the thin tubes 2b and 2b with respect to the thick tube 2a, as illustrated in FIGS. 2B and 2C. (Quick lock mechanism).
Although there are various variations in this quick lock mechanism, in this embodiment, as an example, as shown in FIG. 4, a so-called flareless pipe joint (bite joint) is used. In other words, a sleeve 5 having a reduced diameter portion in which each end portion is gradually reduced in diameter toward each tip end is inscribed in the tightening nut 4 screwed into the thread of the end portion of the thick tube 2a. By gradually screwing the tightening nut 4 into the screw thread 2a, both ends of the sleeve 5 through which the thin tube 2b is inserted are pressed, whereby the sleeve 5 is squeezed and gradually pinched and fixed to the thin tube 2b. It is implemented in a configuration that
The sleeve 5 is preferably an end ring with a part of the circumference cut to make it easier to shrink. The diameters (φ) of the thick tube 2a and the thin tube 2b are not limited to the above dimensions, and the design can be changed as appropriate.

ちなみに本実施例にかかる太管２ａ、細管２ｂは、一例として、薄肉鋼管の外周面に接着剤を塗布しその上にＡＡＳ樹脂等を薄く均一な層状に被覆した、安全で手触りのよい樹脂被覆接着鋼管が好適に用いられる。後述する縦棒３２についても同様の技術的思想とする。 Incidentally, the thick tube 2a and the thin tube 2b according to the present embodiment are, as an example, a safe and easy-to-touch resin coating in which an adhesive is applied to the outer peripheral surface of a thin steel tube and an AAS resin or the like is coated in a thin and uniform layer shape thereon. An adhesive steel pipe is preferably used. The same technical idea applies to a vertical bar 32 described later.

（手すり部２を上下方向に回動させる機構の説明）
また、前記手すり部２（細管２ｂ）は、図３、図５等に示したように、その両端部が、角度調整可能な自在継手（角度可変継手）３１と接続されることにより、上下方向に回動可能な構成とされている。本実施例では、一例として、細管２ｂの端部へ外嵌めして接続する第１セグメント３１ａと、前記縦棒３２の上端部へ外嵌めして接続する第２セグメント３１ｂとを、該第１セグメント３１ａの一端部に形成した凹溝部（抉部）３１ａ’に、第２セグメント３１ｂの側面に連設した（係合部位が半円板状の）連結部３１ｂ’を挿入して係合し、共通する連結ピン（例えばスプリングピン）３１ｃを介して上下方向に回動可能に連結した構成で実施されている。 (Description of mechanism for rotating handrail portion 2 in the vertical direction)
Further, as shown in FIGS. 3 and 5 and the like, the handrail portion 2 (the thin tube 2b) is connected to a universal joint (angle variable joint) 31 whose angle can be adjusted, so that the vertical direction It is set as the structure which can be rotated. In the present embodiment, as an example, the first segment 31a that is externally fitted and connected to the end of the thin tube 2b and the second segment 31b that is externally fitted and connected to the upper end of the vertical bar 32 are connected to the first segment 31a. A connecting portion 31b ′ (engagement site is semicircular) connected to the side surface of the second segment 31b is inserted into and engaged with a concave groove portion (ridge portion) 31a ′ formed at one end portion of the segment 31a. This is implemented by a configuration in which a common connection pin (for example, a spring pin) 31c is connected to be rotatable in the vertical direction.

なお、前記細管２ｂと第１セグメント３１ａ、および縦棒３２と第２セグメント３１ｂは、例えば、端面のつぶれを防止する接続仲介具を介し、側面部に六角孔付き止めねじをねじ込んで固定される。本実施例にかかる自在継手３１の材質は金属製で実施しているがこれに限定されず、アルミニウム製でも合成樹脂製でもよい。また、本実施例にかかる自在継手３１の可変角度はほぼ０〜１８０度に設定しているがこれに限定されず、第１、２セグメント３１ａ、３１ｂの係合部位の形状に応じて適宜設計変更可能である。 The thin tube 2b and the first segment 31a, and the vertical bar 32 and the second segment 31b are fixed by screwing a hexagon socket set screw into the side surface portion via a connection mediator that prevents the end surface from being crushed, for example. . The material of the universal joint 31 according to the present embodiment is made of metal, but is not limited thereto, and may be made of aluminum or synthetic resin. In addition, the variable angle of the universal joint 31 according to the present embodiment is set to approximately 0 to 180 degrees, but is not limited to this, and is appropriately designed according to the shape of the engaging portion of the first and second segments 31a and 31b. It can be changed.

（手すり部２を水平方向に回動させる機構の説明）
さらに、前記手すり部２は、図３、図６等に示したように、前記自在継手３１を介して直角方向に連続する前記縦棒３２が垂直方向に延びた丸管状のソケットに挿入されているから水平方向に回動でき、これに連動する前記手すり部２が水平方向に回動可能な構成とされている。具体的には、前記縦棒３２が、二つのソケット部２０、２１を平行に形成した棒材連結具３３の一方のソケット部２０へ挿入されてその外周を抱持されることにより、他方のソケット部２１へ通された支柱１０ａ（又は１１ａ）に対し、縦棒３２、ひいては手すり部２が水平方向に回動可能な構成とされている。 (Description of the mechanism for rotating the handrail 2 horizontally)
Further, as shown in FIGS. 3 and 6, the handrail portion 2 is inserted into a round tubular socket in which the vertical bar 32 continuous in a perpendicular direction extends through the universal joint 31 and extends in the vertical direction. Therefore, the handrail portion 2 that can be rotated in the horizontal direction and interlocked therewith can be rotated in the horizontal direction. Specifically, the vertical bar 32 is inserted into one socket part 20 of a bar connecting member 33 in which two socket parts 20 and 21 are formed in parallel, and the outer periphery thereof is held, whereby the other The vertical bar 32 and, by extension, the handrail portion 2 are configured to be rotatable in the horizontal direction with respect to the column 10a (or 11a) passed through the socket portion 21.

前記棒材連結具３３は、平行に配置された２本の棒材（縦棒３２と支柱１０ａ又は１１ａと）を連結する連結具であり、前記棒材連結具３３の二つのソケット部２０、２１は、平面方向からみて、その約半分を平行な配置に形成したＳ字形状の主部３３ａと、残り半分を分担して形成する２個の分割片３３ｂ、３３ｂとを抱き合わせて円形に形成される。
よって、前記２本の棒材は、二つの湾曲面部を備えた前記主部３３ａで外周の約半周が抱持され、該棒材を挟んで相対峙させた分割片３３ｂ、３３ｂを、前記主部３３ａの両端部に形成した掛止部へ組み合わせ（噛み合わせ）た上で、主部３３ａと分割片３３ｂ、３３ｂとに穿設した一致するボルト孔へボルト３３ｃおよびツマミ付きボルト３３ｄをねじ込み締結することで、平行状態に連結される。
なお、図示例にかかる棒材連結具３３は、図３の左側の棒材連結具３３を示しており、右側の棒材連結具３３は、前記主部３３ａが反転した平面視Ｓ字形状にする等、全体を反転させ、上述した手法と同様に２本の棒材を平行状態に連結する。 The bar connecting tool 33 is a connecting tool for connecting two bar members (vertical bar 32 and the support column 10a or 11a) arranged in parallel, and the two socket portions 20 of the bar connecting tool 33, 21 is formed in a circular shape by tying together an S-shaped main part 33a formed in a parallel arrangement with about half of the half and two divided pieces 33b and 33b formed by sharing the other half when viewed from the plane direction. Is done.
Therefore, the two bar members are held by the main part 33a having two curved surface parts about half of the outer periphery, and the divided pieces 33b and 33b, which are relatively bent with the bar member interposed therebetween, are divided into the main bars 33a. After being combined (engaged) with the latching portions formed at both ends of the portion 33a, the bolt 33c and the bolt 33d with knob are screwed into the matching bolt holes formed in the main portion 33a and the split pieces 33b and 33b. By doing so, they are connected in a parallel state.
The bar connecting tool 33 according to the illustrated example shows the left bar connecting tool 33 in FIG. 3, and the right bar connecting tool 33 has an S-shape in plan view with the main portion 33a inverted. The whole is inverted, and the two bars are connected in parallel in the same manner as described above.

かくして、前記棒材連結具３３は、前記ボルト３３ｃとツマミ付きボルト３３ｄとをねじ込み締結することで、自立式手すり１０（１１）の支柱１０ａ（１１ａ）と、縦棒３２とを平行状態に連結できる。前記ボルト３３ｃ、３３ｄを緩めて抜き外せば、分割片３３ｂ、３３ｂを分離して前記の連結を解くことも自在にできる。
すなわち、棒材連結具３３は、縦棒３２を連結する側のソケット部２０のツマミ付きボルト３３ｄによる締め付け力を、その縦棒３２が回転自在となる弱めの締め付け力に一旦緩めておく一方、支柱１０ａ（又は１１ｂ）を連結する側のソケット部２１のボルト３３ｃによる締め付け力を回転不可となるように強く締結しておくと、当該縦棒３２、ひいては手すり部２が、支柱１０ａ（又は１１ｂ）に対して水平方向に回動可能な構成となるのである。その後、望ましい回転位置を決めた上で再びツマミ付きボルト３３ｄの締結力を高めて本締め状態にする。
なお、棒材連結具３３は、縦棒３２を連結する側のソケット部２０のツマミ付きボルト３３ｄによる締め付け力が、その縦棒３２が回転自在となる弱めの締め付け力となるように予め設計しておいてもよい。縦棒３２（手すり部２）は常時回転自在の状態であっても、自在式手すり１０、１１と連結してなる連結構造への影響はないに等しいからである。また、前記棒材連結具３３は、図６に示した構成に限定されず、縦棒３２と支柱１０ａ（又は１１ａ）とを平行状態に連結できる構成であれば、適宜設計変更可能である。 Thus, the bar connecting tool 33 connects the column 10a (11a) of the self-supporting handrail 10 (11) and the vertical bar 32 in a parallel state by screwing and fastening the bolt 33c and the bolt 33d with knob. it can. If the bolts 33c and 33d are loosened and removed, the divided pieces 33b and 33b can be separated to release the connection.
That is, the bar connecting tool 33 temporarily loosens the tightening force by the bolt 33d with the knob of the socket portion 20 on the side where the vertical bar 32 is connected to a weak tightening force that allows the vertical bar 32 to rotate, If the tightening force by the bolt 33c of the socket portion 21 on the side to which the support column 10a (or 11b) is connected is strongly tightened so that it cannot be rotated, the vertical bar 32, and thus the handrail portion 2 is connected to the support column 10a (or 11b). ) In the horizontal direction. Then, after determining a desirable rotational position, the fastening force of the bolt 33d with the knob is increased again to be in the final tightening state.
The bar connector 33 is designed in advance so that the tightening force by the knob-attached bolt 33d of the socket portion 20 on the side to which the vertical bar 32 is coupled becomes a weak tightening force that allows the vertical bar 32 to rotate. You may keep it. This is because, even if the vertical bar 32 (handrail portion 2) is always rotatable, it does not affect the connection structure formed by connecting to the free handrails 10 and 11. Further, the bar connecting tool 33 is not limited to the configuration shown in FIG. 6, and can be appropriately changed in design as long as the vertical bar 32 and the column 10 a (or 11 a) can be connected in parallel.

以上説明したように、本発明にかかる連結用手すり補助具１によれば、その手すり部２が伸縮可能な構成で、その棒材連結具３３の一方のソケット部２１に連結した支柱１０ａ（又は１１ａ）に対し、上下方向に回動可能で、水平方向にも回動可能な機構を備えているので、間隔をあけて設置された２つの自立式手すり１０、１１に対し、段差などの高低差がある場所であっても、自在に連結することができる。 As described above, according to the handrail assisting tool 1 for connection according to the present invention, the handrail part 2 can be expanded and contracted, and the column 10a (or the one connected to one socket part 21 of the bar connecting tool 33 (or 11a) is provided with a mechanism that can be rotated in the vertical direction and also in the horizontal direction, so that the level of a step or the like is higher than that of the two self-supporting handrails 10 and 11 that are installed at intervals. Even where there is a difference, they can be connected freely.

次に、前記連結用手すり補助具１を用いた自立式手すりの連結構造について説明する。
例えば図１は、前記連結用手すり補助具１を用いて連結してなる自立式手すり１０、１１の連結構造を示している。一方の自立式手すり１０は上がり框用であり、他方の自立式手すり１１は平置き用であり、両者の間には段差（高低差）が形成されている。
この連結構造を実現するにあたり、先ず準備段階として、前記棒材連結具３３の支柱１０ａ、１１ａ側のボルト３３ｃを抜き外して分割片３３ｂを分離させておく。一方、棒材連結具３３の縦棒３２側のツマミ付きボルト３３ｄを該縦棒３２が回転自在となる弱めの締め付け力に緩めておく。 Next, a self-supporting handrail connection structure using the connection handrail assisting tool 1 will be described.
For example, FIG. 1 shows a connection structure of self-supporting handrails 10 and 11 connected by using the connection handrail auxiliary tool 1. One self-supporting handrail 10 is used for raising heels, and the other self-supporting handrail 11 is used for flat placement, and a step (height difference) is formed between them.
In realizing this connection structure, first, as a preparation stage, the bolts 33c on the pillars 10a, 11a side of the bar connecting member 33 are removed to separate the divided pieces 33b. On the other hand, the knob-attached bolt 33d on the vertical bar 32 side of the bar connector 33 is loosened to a weak tightening force that allows the vertical bar 32 to rotate.

次に、作業員は、その手すり部２の横方向の伸縮長さを調整しながら、該手すり部２が自立式手すり１０、１１の手すり部（上辺部）と連続的に形成できるように傾斜に合わせた位置決めをする。そして、前記棒材連結具３３、３３の主部３３ａ、３３ａの湾曲面部を、対応する支柱１０ａ、１１ａの外周面に押し当てる。作業員は１人よりも２人の方が作業上好ましい。
次に、分離しておいた分割片３３ｂを、対応する主部３３ａと組み合わせ（噛み合わせ）てボルト３３ｃを仮締めし、もって、当該連結用手すり補助具１を支柱１０ａ、１１ａ間に架け渡す。
最後に、架設された前記連結用手すり補助具１について、手すり部２の長さ、傾斜角度、および水平角度の微調整等の点検を行った後、作業員は、前記ボルト３３ｃとツマミ付きボルト３３ｄを本締めすると共に、前記クイックロック機構により手すり部２の細管２ｂを固定する。 Next, the worker is inclined so that the handrail portion 2 can be continuously formed with the handrail portions (upper side portions) of the self-supporting handrails 10 and 11 while adjusting the lateral extension length of the handrail portion 2. Position it according to. Then, the curved surface portions of the main portions 33a and 33a of the bar connecting members 33 and 33 are pressed against the outer peripheral surfaces of the corresponding columns 10a and 11a. In terms of work, two workers are preferable to one.
Next, the divided pieces 33b that have been separated are combined (engaged) with the corresponding main portions 33a, and the bolts 33c are temporarily tightened, so that the connecting handrail assisting tool 1 is bridged between the columns 10a and 11a. .
Finally, after checking the length, inclination angle, and horizontal angle of the handrail portion 2 for the linking handrail assisting tool 1 installed, the operator can check the bolt 33c and the bolt with knob. 33d is finally tightened, and the thin tube 2b of the handrail portion 2 is fixed by the quick lock mechanism.

かくして、隣り合う自立式手すり１０、１１について、一方の自立式手すり１０の支柱１０ａに前記連結用手すり補助具１の一端（の棒材連結具３３）を連結し、他方の自立式手すり１１の支柱１１ａに前記連結用手すり補助具１の他端（の棒材連結具３３）を連結して一体化した自立式手すりの連結構造を実現することができる。
ちなみに、棒材連結具３３が万が一にも下方へずり下がることを防止する手段として、図１の横桟７の上端を棒材連結具３３のソケット２１の下端部に当て、棒材連結具３３のソケット部２１の全長がぴったり嵌まる間隔に、自立式手すりの継手と当該横桟７とが設定されて支柱１１ａに連結されている。 Thus, with respect to the adjacent self-supporting handrails 10 and 11, one end (the bar connection tool 33) of the handrail auxiliary tool 1 for connection is connected to the column 10 a of one self-supporting handrail 10, and the other self-supporting handrail 11 is connected. It is possible to realize a self-supporting handrail connecting structure in which the other end (the bar connecting member 33) of the connecting handrail auxiliary tool 1 is connected to the support column 11a and integrated.
Incidentally, as a means for preventing the bar connecting member 33 from sliding down in the unlikely event, the upper end of the crosspiece 7 in FIG. 1 is applied to the lower end portion of the socket 21 of the bar connecting member 33, and the bar connecting member 33. The joint of the self-supporting handrail and the horizontal rail 7 are set at an interval at which the entire length of the socket portion 21 fits tightly and is connected to the column 11a.

なお、図示例にかかる連結構造は、２本の細管２ｂのうち、一方だけ突き出して実施しているが勿論これに限定されず、自立式手すり１０、１１の間隔が大きく離れている場合等、２本の細管２ｂ、２ｂをそれぞれ適宜突き出して実施する。また、自立式手すり１０、１１は、平面方向からみて、ほぼ同幅で手すり部（上辺部）が直線状に揃った配置で設置しているがこれに限定されない。幅寸が異なったり、いずれかの自立式手すり１０、１１の配置が左方又は右方にずれていたとしても、前記連結用手すり補助具１の手すり部２の長さ、及び水平方向の角度等を適宜調整することにより、支柱１０、１１と一体化した連結構造をフレキシブルに実現することができる。 In addition, the connection structure according to the illustrated example is implemented by protruding only one of the two thin tubes 2b, but of course not limited thereto, and when the interval between the self-supporting handrails 10 and 11 is greatly separated, etc. The two thin tubes 2b and 2b are appropriately protruded and carried out. Moreover, although the self-supporting handrails 10 and 11 are installed in an arrangement in which the handrail portions (upper side portions) are arranged in a straight line with substantially the same width when viewed from the plane direction, the present invention is not limited to this. Even if the width dimension is different or the arrangement of any of the self-supporting handrails 10 and 11 is shifted to the left or right, the length of the handrail part 2 of the connecting handrail assisting tool 1 and the horizontal angle The connection structure integrated with the columns 10 and 11 can be flexibly realized by appropriately adjusting the above.

図７は、連結用手すり補助具の異なる実施例を示している。この連結用手すり補助具１’は、実施例１にかかる連結用手すり補助具１と比し、手すり部２を１本増加して強度・剛性を高めている点が主に相違する。なお、上記実施例１と同一の部材は同一の符号を付してその説明を省略する。
すなわち、図７にかかる連結用手すり補助具１’は、前記手すり部２が上下一対に配置され、該手すり部２の各両端部に前記自在継手３１が設けられ、上下に対応する自在継手３１、３１間に前記棒材連結具３３を備えた縦棒３２を連結して枠状に形成されている。自在継手３１、３１間の縦棒３２の露出寸法は、棒材連結具３３のソケット部２０の全長と合致させることにより、縦棒３２のずり動きを防止する構成としている。
図８は、この連結用手すり補助具１’を用いた連結構造を示している。該連結用手すり補助具１’を自立式手すり１０、１１（の支柱１０ａ、１１ａ）に連結する手法等は、上述した手法等と同様である（前記段落［００２８〜００３１］参照）。 FIG. 7 shows a different embodiment of the handrail aid for connection. The connecting handrail assisting tool 1 'is mainly different from the connecting handrail assisting tool 1 according to the first embodiment in that the handrail part 2 is increased by one to increase the strength and rigidity. In addition, the same member as the said Example 1 attaches | subjects the same code | symbol, and abbreviate | omits the description.
That is, in the connecting handrail auxiliary tool 1 ′ according to FIG. 7, the handrail portion 2 is arranged in a pair of upper and lower portions, the universal joints 31 are provided at both ends of the handrail portion 2, and the universal joint 31 corresponding to the upper and lower sides. , 31 is formed in a frame shape by connecting a vertical bar 32 provided with the bar connector 33. The exposed dimension of the vertical bar 32 between the universal joints 31 and 31 is configured to prevent the vertical bar 32 from sliding, by matching the overall length of the socket portion 20 of the bar connecting member 33.
FIG. 8 shows a connecting structure using the connecting handrail auxiliary tool 1 ′. The method of connecting the handrail auxiliary tool 1 ′ for connection to the self-supporting handrails 10 and 11 (the support columns 10a and 11a) is the same as the method described above (see paragraphs [0028 to 0031] above).

この連結用手すり補助具１’を用いて自立式手すり１０、１１を連結した連結構造によれば、上記実施例１にかかる連結構造と比し、補助具１’自体の強度・剛性を高めることはもとより、連結構造全体の強度・剛性を高めることができ、より安定性を増した連結構造を実現することができる。また、手すり部２を上下２段に設けたことにより、要介護者等が手すり部２を掴むバリエーションが増大し、より良好な歩行（掴まり歩き）を実現することができる。 According to the connecting structure in which the self-supporting handrails 10 and 11 are connected using the connecting handrail auxiliary tool 1 ′, the strength and rigidity of the auxiliary tool 1 ′ itself are increased as compared with the connecting structure according to the first embodiment. Needless to say, the strength and rigidity of the entire connection structure can be increased, and a connection structure with improved stability can be realized. In addition, by providing the handrail portion 2 in two upper and lower stages, a variation in which a care recipient or the like needs to grab the handrail portion 2 is increased, and better walking (gripping and walking) can be realized.

図８は、連結用手すり補助具の異なる実施例を示している。この連結用手すり補助具は、実施例１にかかる連結用手すり補助具１と比し、その自在継手３１の形態に工夫を施している点が相違する。なお、上記実施例１と同一の部材は同一の符号を付してその説明を省略する。 FIG. 8 shows a different embodiment of the handrail aid for connection. This connecting handrail assisting tool is different from the connecting handrail assisting tool 1 according to the first embodiment in that the form of the universal joint 31 is devised. In addition, the same member as the said Example 1 attaches | subjects the same code | symbol, and abbreviate | omits the description.

すなわち、図８にかかる連結用手すり補助具は、その自在継手３１の第１セグメント３１ａの凹溝部（抉部）３１ａ’と第２セグメント３１ｂの半円板状の連結部３１ｂ’とに、この両セグメントを共通に貫通する、手すり中心軸方向が長径の貫通孔３１ｃ’に連結ピン３１ｃを挿入し、当該凹溝部３１ａ’と連結部３１ｂ’とに、互いに嵌め合うダボ９とダボ穴８とが形成されている。より具体的には、前記凹溝部３１ａ’の中央部に突き出したダボ９を形成し、前記ダボ９の先端部は、前記略半円板状の連結部３１ｂ’の先端外周に当たりながらその外周上を進む形で、一端部がフリーとなった手すり部２を上方向に回動させて跳ね上げると、図８（Ｂ）に示したように、前記連結部３１ｂ’側に設けたダボ穴８に、貫通孔３１ｃ’が長径の分、前記凹溝部３１ａ’側に設けたダボ９が落ち込んで嵌まり、当該手すり部２の起立した姿勢を保持することができる。 That is, the handrail auxiliary tool for connection according to FIG. 8 includes the concave groove portion (saddle portion) 31a ′ of the first segment 31a of the universal joint 31 and the semicircular plate-like connection portion 31b ′ of the second segment 31b. A dowel 9 and a dowel hole 8 are inserted into the through-hole 31c ′ having a long axis in the handrail central axis direction and penetrating both segments in common, and fitted into the recessed groove portion 31a ′ and the connecting portion 31b ′. Is formed. More specifically, a dowel 9 protruding from the central portion of the concave groove portion 31a ′ is formed, and the tip portion of the dowel 9 is on the outer periphery of the substantially semi-disc-shaped connecting portion 31b ′ while hitting the outer periphery of the tip portion. When the handrail portion 2 with one end free is turned up and flipped up, as shown in FIG. 8 (B), the dowel hole 8 provided on the connecting portion 31b ′ side is formed. In addition, the dowel 9 provided on the concave groove portion 31a ′ side is lowered and fitted by the length of the through-hole 31c ′, so that the handrail portion 2 can be held upright.

また、一端部がフリーとなった手すり部２を下方向に回動させて折り畳むと、図９（Ｂ）に示したように、自立式手すり１１の支柱１１ａと平行状態となるが、この点においては、実施例１にかかる連結用手すり補助具１と同様である。 Further, when the handrail portion 2 with one end free is turned downward and folded, as shown in FIG. 9 (B), the handrail portion 11 becomes parallel to the column 11a of the self-supporting handrail 11. Is the same as the handrail assisting tool 1 for connection according to the first embodiment.

これらは、前記手すり部２を一時的に外しておきたい場合のバリエーションであるが、前記図９（Ａ）にかかる跳ね上げ式によれば、図９（Ｂ）にかかる折り畳み式と比し、自立式手すりの設置間隔が大きい等、手すり部２の長さ寸法を自立式手すり１１の支柱１１ａの高さ寸法よりも長く伸ばして連結している場合に、手すり部２の長さを縮めることなくそのままの長さで起立させておくことができる。よって、再度連結する際には、手すり部２を伸ばす等の手間をかけることなくそのまま下ろして即座に連結構造を実現できる利点がある。
なお、前記連結部３１ｂ’側にダボ９を設け、凹溝部３１ａ’側にダボ穴８を設けても同様に実施できる。 These are variations when it is desired to temporarily remove the handrail portion 2, but according to the flip-up type according to FIG. 9 (A), compared to the folding type according to FIG. 9 (B), When the length of the handrail 2 is extended longer than the height of the column 11a of the self-supporting handrail 11 such as when the installation distance of the self-supporting handrail is large, the length of the handrail 2 is reduced. It can stand upright as it is. Therefore, when connecting again, there exists an advantage which can implement | achieve a connection structure immediately without taking down time, such as extending the handrail part 2, as it is.
In addition, it can implement similarly even if the dowel 9 is provided in the said connection part 31b 'side, and the dowel hole 8 is provided in the ditch | groove part 31a' side.

図１０のように自立式手すりの支柱１１’の上端の継手が、本出願人が所有している特許第４４７５００５号の様な継手の場合、支柱に対し上下方向および水平方向に回動可能な自在継手であるから、上下方向および水平方向に回動可能に保持する保持機構が構築できて、同様な連結用手すり補助具の構成が可能である。尚、両端を自在継手で実施する場合も考えられるが、一方は自在継手３１と棒材連結具３３との保持機構で構成する方が、一方の端の連結を外し易く跳ね上げたい場合等に好ましい。 As shown in FIG. 10, in the case where the joint at the upper end of the pillar 11 'of the self-supporting handrail is a joint such as Japanese Patent No. 4475005 owned by the present applicant, the joint can be rotated vertically and horizontally with respect to the pillar. Since it is a universal joint, it is possible to construct a holding mechanism that holds it pivotably in the vertical direction and the horizontal direction, and a similar construction of a handrail assisting tool for connection is possible. In addition, although the case where both ends are implemented with a universal joint is also conceivable, when one side is configured by a holding mechanism of the universal joint 31 and the bar connecting member 33, it is easier to disconnect the one end and jump up. preferable.

以上、実施例１〜４を図面に基づいて説明したが、本発明はこの限りではなく、その技術的思想を逸脱しない範囲において、当業者が通常に行う設計変更、応用のバリエーションの範囲を含むことを念のために言及する。 As mentioned above, although Example 1-4 was demonstrated based on drawing, this invention is not this limitation, In the range which does not deviate from the technical idea, the range of the design change normally performed by those skilled in the art and the variation of application is included.
