Description

この発明は、たとえば薄肉鋼管の外周面に合成樹脂を薄肉の均等厚さに被覆した、外径が２８ｍｍ〜３５ｍｍ程度の軽量構造用の樹脂被覆鋼管（以下、単に樹脂被覆鋼管という。）又は樹脂被覆等の無い鋼管、又はアルミニウムや合成樹脂その他の材質による軽量構造用管材、更には各種材質による中実の軽量構造用棒材（以上の各材をまとめて管材と総称する。）をそれぞれ相互に連結等して組み立てる手段である連結用継手と、及び前記の各軽量構造用管材を相互に連結して組み立てられた二種以上の管材構造物、具体的にはいわゆる介助用具を相互に連結して機能複合化した管材構造物（介助用具）の技術分野に属する。 In the present invention, for example, a resin-coated steel pipe (hereinafter simply referred to as a resin-coated steel pipe) or a resin for light-weight structures having an outer diameter of about 28 mm to 35 mm, in which a synthetic resin is coated on the outer peripheral surface of a thin-walled steel pipe to a uniform thickness. Non-coated steel pipes, lightweight structural pipes made of aluminum, synthetic resin, or other materials, and solid lightweight structural bars made of various materials (the above materials are collectively referred to as pipes). A coupling joint, which is a means for assembling and connecting to each other, and two or more kinds of pipe structures constructed by coupling the light-weight structural pipes to each other, specifically, so-called aids As such, it belongs to the technical field of functionally-combined pipe structures (assisting tools).

従来、上記した軽量構造用管材は種々公知、周知である。また、同前の管材を用いて組み立てられた管材構造物（介助用具）も各種のものが知られ、それぞれ用途に応じた産業分野で実用に供されている。
例えば、下記の特許文献１に開示された「立ち上がり動作補助具」も、上記の管材を用いて組み立てられた管材構造物の有用な一種として知られている。すなわち、介護、介助が必要とされる病弱者、要介護者らのベッド脇に設置して、ベッドから下りて歩行する際に、自助動作の目的で掴まり立ちをするため、又は逆に歩行してきた要介護者らがベッドへ横たわる際などに掴まり、自助動作として姿勢、体勢を変換する際の補助具として便利に使用されている。 Conventionally, various lightweight structural pipes as described above are known and well known. Various types of tube structures (assisting tools) assembled using the previous tube materials are also known and are put to practical use in industrial fields according to their use.
For example, the “rise operation assisting tool” disclosed in the following Patent Document 1 is also known as a useful type of tube structure assembled using the above-described tube material. In other words, it is installed beside the beds of sick people who need care or assistance, and those who need care, and when walking down from the bed, to grab and stand for the purpose of self-help operation, or in reverse It is used conveniently as an auxiliary tool for changing posture and body posture as a self-help operation.

実用新案登録第３１２７５４２号公報Utility Model Registration No. 3127542

上記特許文献１に開示された「立ち上がり動作補助具」の実用性、機能性及び有用性は、それぞれ既に実証済みである。
しかし、更なる改善、改良の余地があることも、現状で色々知得されている。
例えば上記の「立ち上がり動作補助具」を、介護や介助が必要とされる病弱者、要介護者らのベッド脇に設置して、要介護者らがベッドから下りて歩行する際に掴まり、自助動作として床上に立ったり、又は逆に床を歩行してきた要介護者らがベッドへ座ったり横たわる目的で掴まり、姿勢、体勢を変える動作の際にも、上記「立ち上がり動作補助具」は、単に垂直に立っている補助具として静止しているだけにすぎない。
そのため病弱者、要介護者らにとっては、使用上になお物足りないものがあり、要介護者らの自助動作の助けに更なる改良、改善の余地があると考えられている。
例えば利用者たる要介護者らが掴まり立ちを行いつつ、ベッドから立ち上がって、更に水平方向へ回りつつ歩行動作へ移る際に、「立ち上がり動作補助具」が、水平２次元方向へ掴まり歩く動作を助ける「補助手すり」を備えて、しかも前記動作を助けるのに好ましい高さ、向きに付属していると、一層、要介護者らの自助動作を助ける補助具として、要介護者らの利用意欲、意気込みを高め、要介護者らによる「立ち上がり動作補助具」の利用頻度が高まる。ひいては要介護者らの機能回復に作用、効果が高いものになると考えられる。 The practicality, functionality, and usefulness of the “rising motion assisting tool” disclosed in Patent Document 1 have already been proven.
However, it is well known that there is room for further improvement and improvement.
For example, the above-mentioned “stand-up motion assisting device” is installed beside the bed of a sick person or care recipient who needs care or assistance, and when the care recipient descends from the bed and walks, self-help The above-mentioned “stand-up motion assisting device” is also used when the care recipients who are standing on the floor as an operation or conversely walking for the purpose of sitting or lying on the bed and changing their posture and posture are simply It is just stationary as an auxiliary tool standing vertically.
For this reason, there are things that are still unsatisfactory in use for the sick and those who need care, and it is considered that there is room for further improvement and improvement in helping the self-help operations of those requiring care.
For example, when a care recipient who is a user grabs and stands, when standing up from the bed and moving to a walking motion while turning further in the horizontal direction, the “rising motion assisting device” grabs and walks in the horizontal two-dimensional direction. If it is equipped with an "auxiliary handrail" to assist and is attached to a height and orientation that is favorable for assisting the above-mentioned movement, it will further increase the willingness of the care recipients to use as an auxiliary device to assist the self-help movement of the care recipients. Increases enthusiasm and increases the frequency of use of “start-up assisting devices” by care recipients. Eventually, it will be effective and effective in restoring the functions of the care recipients.

上記のような思考過程を経て上記「補助手すり」の基本概念ないし設計思想は生まれたが、さてこの「補助手すり」を、既存の「立ち上がり動作補助具」に対して、どのような手段、構成で、上記の使用、利用に最適な構成・態様で付設するかの点で、本発明の新たな解決課題が生まれた。
すなわち、「補助手すり」を如何様に構成し、既存の「立ち上がり動作補助具」に対して如何なる態様で付設するかということである。付設する手段が容易で、実用性と自在性に既往の技術で対応が可能であることが望まれる。そして、要介護者らに自助動作の意識向上を促し、その使用に至便な構成を実現することが望まれるからである。 The basic concept or design philosophy of the “auxiliary handrail” was born through the above thinking process. Now, what kind of means and configuration is used for this “auxiliary handrail” with respect to the existing “stand-up assisting device”? Thus, a new problem to be solved of the present invention has been born in terms of whether or not it is attached in a configuration / mode optimal for the use and utilization described above.
That is, how the “auxiliary handrail” is configured and how it is attached to the existing “stand-up motion assisting tool”. It is desirable that the means to be attached is easy, and that practicality and flexibility can be handled by existing techniques. And it is because it is desired to raise the awareness of self-help operation to care recipients and to realize a convenient configuration for its use.

よって、本発明の目的は、既存の「立ち上がり動作補助具」に対して、「補助手すり」を付設する手段と作業工程が容易で、付設した「補助手すり」の使い勝手と機能性に優れ、要介護者らの自助動作を補助する機能に十分な構成で、しかも「補助手すり」の存在が「立ち上がり動作補助具」の利用、使用の利便性を高め、要介護者らに自助動作の意識向上を促すこと、及び「補助手すり」を「立ち上がり動作補助具」へ付設する上で必要・十分な条件と機能を備えた管材構造物相互の連結用継手及び管材構造物を提供することである。 Therefore, the object of the present invention is that the means and work process for attaching the “auxiliary handrail” to the existing “stand-up motion assisting tool” are easy, the usability and functionality of the attached “auxiliary handrail” are excellent, and it is necessary. Constructed enough to support the caregivers' self-help movements, and the presence of the “auxiliary handrail” improves the convenience of using and using the “stand-up movement aids”, and raises the awareness of self-help movements for the care recipients. And providing a joint for connecting pipe structures and a pipe structure having the necessary and sufficient conditions and functions for attaching an “auxiliary handrail” to a “stand-up motion assisting tool”.

以下に、先ず図１と図３及び図４に基づいて、管材連結用継手３の構成及び機能を説明する。
図示した連結用継手３は、図１と図４に組み立て完成の状態を例示し、図３に各構成要素を関係配置に分離して示したとおり、管材を用いて組み立てられた床置き型手すり１の垂直な支柱用管材１０へ、補助手すり２の縦管材２０を、事後的に相互に一定の取り付け姿勢に連結することが可能に構成されている。
因みに、補助手すり２は、四隅位置のＬ型継手２２で縦辺の管材２０及び２４と横辺の管材２３とをそれぞれ連結して構成されている。
また、床置き型手すり１は、図１Ｃに例示し、上記特許文献１に開示されたとおり、平行に相対峙する配置とした２本の支柱管材１０、１０を、平板形状のベース板１１の上に垂直に固定して立て、前記支柱管材１０、１０の上下方向に間隔をあけて配置した複数本の横桟１２をエルボ型継手１３、及びＴ型継手１４を使用して接合し組み立てられている。 Below, based on FIG.1, FIG3 and FIG.4, the structure and function of the coupling 3 for pipe connection are demonstrated first.
The illustrated coupling joint 3 is illustrated in FIGS. 1 and 4 assembling completed, and as shown in FIG. 3 with each component separated into a relative arrangement, a floor-standing handrail assembled using pipes. The vertical pipe member 20 of the auxiliary handrail 2 can be connected to the vertical support pipe member 10 of one vertical post-installation with each other in a fixed posture.
Incidentally, the auxiliary handrail 2 is configured by connecting the vertical side pipe materials 20 and 24 and the horizontal side pipe material 23 with L-shaped joints 22 at the four corner positions.
Moreover, the floor-standing handrail 1 is illustrated in FIG. 1C, and as disclosed in the above-mentioned Patent Document 1, the two support pipe members 10, 10 arranged so as to face each other in parallel are arranged on the flat base plate 11. A plurality of horizontal rails 12 which are vertically fixed and are vertically spaced apart from each other in the vertical direction of the support pipe members 10 and 10 are joined and assembled using an elbow joint 13 and a T joint 14. ing.

本発明の管材連結用継手３は、上記した二つの管材構造物、即ち床置き型手すり１と補助手すり２それぞれの連結するべき２本の管材１０と２０を、図２に例示した態様で、略平行に相対峙する配置に並べて接近させ、これら２本の管材１０と２０の外周部を個別に、平行状態に抱持した形に連結する構成とされている。
その故に、管材連結用継手３を構成する主部材３１には、図３に示したとおり、前記連結するべき２本の管材１０と２０の外周部を、個別に平行状態に抱持することが可能な２条の半割り形状の凹溝部３１１と３１２が形成されている。よって、この主部材３１は、図３、図４に示したとおり、前記２条の半割り形状の凹溝部３１１と３１２が形成された結果として、管材の横断面方向に見た平面形状がＳ字形状に形成されている。
この連結用継手３は、上記主部材３１の２条の凹溝部３１１、３１２のうち、一方（中央寄り）の凹溝部３１２のみを筒状に補完する半割り形状の凹溝部３２１を備えた副部材３２と、前記主部材３１の残る他方（端寄り）の凹溝部３１１を筒状に補完する半割り形状の凹溝部３３１を備えた第三の部材３３との組み合わせとして構成されている。
従って、管材１０と管材２０とを個別に抱持する構成となり、管材２０は個別に着脱自在であり、ひいては補助手すり２の取り付け、取り外しは一元的な手間で自在に可能となっている。 In the embodiment illustrated in FIG. 2, the pipe connection joint 3 of the present invention includes two pipe structures 10 and 20 to be connected to the above-described two pipe structures, that is, the floor-standing handrail 1 and the auxiliary handrail 2, respectively. The two pipe members 10 and 20 are arranged so as to approach each other in parallel and relatively close to each other, and the outer peripheral portions of the two pipe members 10 and 20 are individually connected in a shape held in parallel.
Therefore, as shown in FIG. 3, the main member 31 constituting the pipe connection joint 3 can individually hold the outer peripheral portions of the two pipes 10 and 20 to be connected in a parallel state. Two possible half-grooves 311 and 312 are formed. Therefore, as shown in FIGS. 3 and 4, the main member 31 has a planar shape viewed in the cross-sectional direction of the tube material as a result of the formation of the two half-divided concave grooves 311 and 312. It is formed in a letter shape.
The coupling joint 3 includes a sub-divided groove portion 321 that complements only one of the two groove portions 311 and 312 of the main member 31 in a cylindrical shape. It is configured as a combination of the member 32 and a third member 33 provided with a half-grooved groove portion 331 that complements the remaining (end-side) groove portion 311 of the main member 31 in a cylindrical shape.
Accordingly, the tubular material 10 and the tubular material 20 are individually held, and the tubular material 20 can be individually attached and detached. As a result, attachment and removal of the auxiliary handrail 2 can be freely performed in a unified manner.

上記主部材３１と副部材３２は更に、上記床置き型手すり１における垂直な支柱用管材１０へ一定の傾斜角度（図示例では約９０度。但し、この限りではない。）で連なる第二の管材１２（図示例では横桟に該当）の外周を相互に合一に抱持する半割り形状の凹溝部３１３’と３２３’をそれぞれ形成された一対の半割りソケット３１３と３２３が、繋ぎ腕部３１４と３２４を介して一体的に設けられている。
そして、前記主部材３１の残る他方の凹溝部３１１を筒状に補完する半割り形状の凹溝部３３１を備えた第三の部材３３と組み合わせる構成とされている。 The main member 31 and the sub member 32 are further connected to the vertical support pipe 10 in the floor-type handrail 1 at a constant inclination angle (about 90 degrees in the illustrated example, but not limited to this). A pair of half-sockets 313 and 323 formed with half-grooves 313 'and 323' each holding the outer periphery of the tube material 12 (corresponding to a horizontal rail in the illustrated example) together are connected arms. They are provided integrally via the portions 314 and 324.
And it is set as the structure combined with the 3rd member 33 provided with the half-groove-shaped groove part 331 which complements the other groove part 311 with which the said main member 31 remains in a cylinder shape.

その上で、上記の主部材３１と副部材３２及び第三の部材３３は、各々の凹溝部３１２と３２１及び３１１と３３１で抱持した上記２本の管材１０と２０を強固に支持し連結する手段として、上記主部材３１の繋ぎ腕部３１４の半割ソケット３１３の先端部には一例としてダブテール形状の凹部３１６が形成されている。他方、副部材３２の繋ぎ腕部３２４の半割ソケット３２３の先端部には同じダブテール形状の凸部３２５がちょうど前記凹部３１６へ結合する仕様で形成されている。
更に、双方の繋ぎ腕部３１４と３２４には、各半割ソケット３１３、３２３のおよそ付け根の位置に、一方には通孔３２６を、他方にはねじ孔３１６が形成されている。従って、ねじ３６を通孔３２６の側からねじ孔３１６へ向けてねじ込み締結することにより、双方の繋ぎ腕部３１４と３２４を一体的に緊結できる構成とされている。 In addition, the main member 31, the sub member 32, and the third member 33 firmly support and connect the two pipe members 10 and 20 held by the respective recessed groove portions 312 and 321 and 311 and 331, respectively. For example, a dovetail recess 316 is formed at the tip of the half socket 313 of the connecting arm 314 of the main member 31 as an example. On the other hand, the same dovetail-shaped convex portion 325 is formed at the front end portion of the half socket 323 of the connecting arm portion 324 of the sub member 32 so as to be coupled to the concave portion 316.
Further, both connecting arm portions 314 and 324 are formed with through holes 326 on one side and screw holes 316 on the other side at the positions of the roots of the respective half sockets 313 and 323. Therefore, both the connecting arm portions 314 and 324 can be integrally fastened by screwing and fastening the screw 36 from the side of the through hole 326 toward the screw hole 316.

つまり、上記床置き型手すり１へ補助手すり２を連結して付設する手順としては、先ず副部材３２の半割ソケット３２３が有する先端部のダブテール形状の凸部３２５を、主部材３１の繋ぎ腕部３１４の先端の半割ソケット３１３の前記ダブテール形状の凹部３１６へ嵌め合わせつつ双方の半割ソケット３１３と３２３を結合させ、第二の管材１２を抱持させる。
そして、主部材３１の一方の凹溝部３１２へ、床置き型手すり１の垂直な支柱用管材１０を横方向から嵌め込み、同時に反対側から副部材３２の凹溝部３２１を前記凹溝部３１２へ組み合わせて支柱用管材１０を支持させる。
その上で、上記ねじ３６を繋ぎ腕部３２４の通孔３２６の側から、主部材３１の繋ぎ腕部３１４のネジ孔３１６へねじ込み締結することにより、双方の半割ソケット３１３と３２３同士を仮に緊結して、第二の管材１２との結合を先ずは達成する。 That is, as a procedure for connecting and attaching the auxiliary handrail 2 to the floor-type handrail 1, first, the dovetail-shaped convex portion 325 at the tip end of the half socket 323 of the sub member 32 is connected to the connecting arm of the main member 31. The two half sockets 313 and 323 are joined together while being fitted into the dovetail-shaped recess 316 of the half socket 313 at the tip of the portion 314, and the second pipe member 12 is held.
Then, the vertical support pipe 10 of the floor-standing handrail 1 is fitted from one side to the other groove portion 312 of the main member 31, and at the same time, the groove portion 321 of the sub member 32 is combined with the groove portion 312 from the opposite side. The support pipe 10 is supported.
Then, by screwing the screw 36 from the through hole 326 side of the connecting arm portion 324 into the screw hole 316 of the connecting arm portion 314 of the main member 31, both the half sockets 313 and 323 are temporarily connected. Tightly, the connection with the second pipe 12 is first achieved.

そして、主部材３１の凹溝部３１２と副部材３２の凹溝部３２１とで抱持した床置き型手すり１の支柱用管材１０は、副部材３２の凹溝部３２１よりも端側（先端側）部分に形成した厚肉条の段部３２８に設けてある通孔３２７を通じて、主部材３１の対応位置に設けたねじ孔３１０へ止めボルト３５をねじ込み強固に締め付けることで、主部材３１と副部材３２とは、各々の半割り形状の凹溝部３１２と３２１で床置き型手すり１の支柱用管材１０を強力に挟持させ一体化結合した形に組み立てられる。最終的には、前記ねじ３６も強固に締結して第二の管材１２との結合を本締め状態にしておく。 The support pipe member 10 of the floor-standing handrail 1 held by the concave groove portion 312 of the main member 31 and the concave groove portion 321 of the sub member 32 is an end side (front end side) portion from the concave groove portion 321 of the sub member 32. The fixing bolt 35 is screwed into the screw hole 310 provided at the corresponding position of the main member 31 through the through-hole 327 provided in the thick-walled step 328 formed on the main member 31, and is firmly tightened. Is assembled into a form in which the strut pipes 10 of the floor-type handrail 1 are strongly sandwiched and integrally joined by the half-grooved concave groove portions 312 and 321. Eventually, the screw 36 is also firmly fastened, and the connection with the second pipe member 12 is in a final tightening state.

次に、第三の部材３３を、上記主部材３１の外寄りに位置する半割り形状の凹溝部３１１の位置へ取り付ける手段として、主部材３１の凹溝部３１１の外寄り縁部に、一例としてダブテール形状の凸部３１７が形成されている。また、同半割り形状の凹溝部３１１よりも中央側部分は厚肉に形成して階段形状の受け段部３１８が形成されている。
他方、第三の部材３３における外側縁部には、上記主部材３１の外寄り縁部に位置するダブテール形状の凸部３１７へ嵌まり結合されるダブテール形状の凹部３３２が形成されている。
そして、図４で類推可能なように、第三の部材３３の中央側端部は、主部材３１の上記中間部に形成された受け段部３１８へ密接する形態とされ、更に手動操作用のハンドル３４０をねじ込む止めボルト３４を通す通孔３３３が設けられている。これに対応して、前記主部材３１の中央部位には、上述した副部材３２を主部材３１の前記受け段部３１８へ固定する止めボルト３５用に設けた上下２箇のねじ孔３１０の中間部位に、１箇の貫通孔
３１９を設けて、この貫通孔３１９へ止めボルト３４を外側から通して、その先端のねじ部へハンドル３４０（ナット部材）のネジ孔をねじ込むことで、強固に締結する構成とされている。止めボルト３４の頭３４’は六角形状で、差し込む貫通孔３１９の入り口３１９’も同形状とされ、ボルト３４の頭３４’が同所に嵌まって収まり、止めボルト３４の回転止め作用を働く構成とされている。 Next, as a means for attaching the third member 33 to the position of the half-grooved groove 311 located on the outer side of the main member 31, as an example, on the outer edge of the groove 311 of the main member 31. A dovetail-shaped convex portion 317 is formed. Further, the center side portion of the half-divided groove portion 311 is formed thicker so that a stepped receiving portion 318 is formed.
On the other hand, a dovetail-shaped concave portion 332 is formed on the outer edge portion of the third member 33 and is fitted into and coupled to the dovetail-shaped convex portion 317 located at the outer edge portion of the main member 31.
Then, as can be inferred from FIG. 4, the center side end portion of the third member 33 is in close contact with the receiving step portion 318 formed in the intermediate portion of the main member 31, and further for manual operation. A through hole 333 is provided through which a set bolt 34 into which the handle 340 is screwed is passed. Correspondingly, at the central portion of the main member 31, an intermediate portion between two upper and lower screw holes 310 provided for the set bolt 35 for fixing the above-described sub member 32 to the receiving step portion 318 of the main member 31. A single through hole 319 is provided at the site, and a fastening bolt 34 is passed through the through hole 319 from the outside, and the screw hole of the handle 340 (nut member) is screwed into the threaded portion of the tip, thereby tightening firmly. It is supposed to be configured. The head 34 ′ of the set bolt 34 has a hexagonal shape, and the entrance 319 ′ of the through-hole 319 to be inserted has the same shape. The head 34 ′ of the bolt 34 fits and fits in the same place, and the rotation stop function of the set bolt 34 works. It is configured.

上記のようにして、床置き型手すり１の垂直な支柱用管材１０へ、上述の手順で主部材３１と副部材３２を取り付けた上で、次に、同じ主部材３１の残る凹溝部３１１と、第３の部材３３の半割り形状の凹溝部３３１とを利用して、補助手すり２の同じく縦辺である管材２０を連結する作業を進める。
その手順としては、まず前記床置き型手すり１の垂直な支柱用管材１０へ、補助手すり２の縦辺である管材２０を略平行な配置に相対峙させる。
そして、主部材３１の半割形状の凹溝部３１１の外側縁部に設けた、一例としてのダブテール形状の凸部３１７へ、第三の部材３３の一側縁に設けたダブテール形状の凹部３３２を嵌め付けて結合する。と同時に、前記主部材３１の凹溝部３１１へ嵌めた管材２０の残り半周分を第三の部材３３の半割形状の凹溝部３３１で抱持させる。
そして、前記主部材３１の半割形状の凹溝部３１１が形成された部分よりも中央側の中間部位３１８に設けた貫通孔３１９へ、更に副部材３２の該貫通孔３１９と共通する孔３２９を通って、第三の部材３３の通孔３３３を通じて挿入したボルト３４の先端側へハンドル３４０のネジ孔をねじ込み強固に締め付けることで、床置き型手すり１の支柱用管材１０へ補助手すり２を連結して複合化した介助用具を実現することができる。又は、ネジを切った貫通孔３１９にして、それに第三の部材３３の通孔３３３に通して挿入したボルトをねじ込んで、補助手すり２を固定する形態にも出来る。
もとより、上記の作業手順を逆に進めることで、床置き型手すり１から補助手すり２を分離すること、或いは補助手すり２の連結位置や連結態様(向き)を変更すること、その他の調節を自在に行うことができる。 As described above, the main member 31 and the sub member 32 are attached to the vertical column tube 10 of the floor-standing handrail 1 in the above-described procedure, and then the remaining groove 311 of the same main member 31 Using the half-shaped concave groove 331 of the third member 33, the work of connecting the pipe material 20 which is also the vertical side of the auxiliary handrail 2 is advanced.
As the procedure, first, the pipe material 20 which is the vertical side of the auxiliary handrail 2 is made to face the vertical support pipe material 10 of the floor-standing handrail 1 in a substantially parallel arrangement.
Then, a dovetail-shaped concave portion 332 provided on one side edge of the third member 33 is provided on an outer side edge portion of the half-shaped concave groove portion 311 of the main member 31, as an example of the dovetail-shaped convex portion 317. Fit and join. At the same time, the remaining half circumference of the tube material 20 fitted in the concave groove portion 311 of the main member 31 is held by the half-shaped concave groove portion 331 of the third member 33.
Then, a hole 329 common to the through hole 319 of the sub member 32 is further formed in the through hole 319 provided in the intermediate portion 318 on the center side of the part where the half-shaped concave groove portion 311 of the main member 31 is formed. The auxiliary handrail 2 is connected to the column tube 10 of the floor-type handrail 1 by screwing the screw hole of the handle 340 into the tip side of the bolt 34 inserted through the through-hole 333 of the third member 33 and tightening firmly. Thus, a composite assisting device can be realized. Alternatively, the auxiliary handrail 2 can be fixed by screwing a bolt inserted through the through hole 333 of the third member 33 into the threaded through hole 319.
Of course, by moving the above procedure in reverse, the auxiliary handrail 2 can be separated from the floor-type handrail 1 or the connection position and connection mode (orientation) of the auxiliary handrail 2 can be changed, and other adjustments can be made freely. Can be done.

なお、図２のように、補助手すり２の縦辺である管材２０の管軸方向の上部の一部分にだけ平面部２１を設け（図１Ａ参照）、この平面部２１へ合致させる第三の部材３３の平面部３３５を形成して（図３を参照）その余の部分は円管形状とし、補助手すり２の連結態様（向き）を特定する構成で実施することができる。前記の向きを変更する場合には、ハンドル３４０を回してボルト３４をゆるめ、管材２０を滑らせることが可能な位にまで抱持強度を緩めて、第三の部材３３の抱持を一旦解き、管材２０の平面部２１を形成していない部位にまで位置をずらせ、その位置で補助手すり２を所望の角度位置まで回転し、その後に元位置まで戻して同位置の平面部に合致させ、その上で前記ハンドル３４０を再び締め込むと、第三の部材３３を完全に分離させないで補助手すり２を回転し角度位置を回転させることができ、例えば図６Ａ、Ｂをはじめ、図７Ａ〜Ｃのように変更することができるし、作業性に優れる。
また、図１Ｃに例示したようにベッド１００に対してセットした使用状態の床置き型手すり１に対して、上記のハンドル３４０を突き出した向きが悪く、使用者の邪魔になることもあるが、この場合には上記第三の部材３３を貫通させる止めボルトの頭３４’の向き（図２を参照）を反対側に変えた構成でも同様に実施できる。 As shown in FIG. 2, a flat portion 21 is provided only at a portion of the upper portion in the tube axis direction of the pipe material 20 that is the vertical side of the auxiliary handrail 2 (see FIG. 1A), and a third member that matches the flat portion 21. The flat part 335 of 33 is formed (refer FIG. 3), and the other part is made into a circular pipe shape, and it can implement by the structure which specifies the connection aspect (direction) of the auxiliary handrail 2. FIG. In the case of changing the direction, the handle 340 is turned to loosen the bolt 34, loosen the holding strength to such an extent that the tube material 20 can be slid, and temporarily unholds the third member 33. , Shift the position to the portion of the tube material 20 where the flat portion 21 is not formed, rotate the auxiliary handrail 2 to a desired angular position at that position, and then return to the original position to match the flat portion of the same position, When the handle 340 is tightened again, the auxiliary handrail 2 can be rotated and the angular position can be rotated without completely separating the third member 33. For example, FIGS. 6A and 7C and FIGS. It can be changed like this, and it is excellent in workability.
In addition, as shown in FIG. 1C, the floor handle type handrail 1 in the use state set with respect to the bed 100 is poorly protruded from the handle 340 and may interfere with the user. In this case, a configuration in which the direction of the head 34 ′ of the stop bolt that penetrates the third member 33 (see FIG. 2) is changed to the opposite side can be implemented in the same manner.

次に、上記のようにして床置き型手すり１の支柱用管材１０へ補助手すり２を連結して複合化した介助用具を実現するにあたり、補助手すり２が支柱用管材１０を中心として回転（旋回）することは、ある程度健常な利用者にとっては使い勝手の良い場合もある。しかし、逆に足取りがおぼつかないほど重症の利用者にとっては、補助手すり２が支柱用管材１０を中心として回転（旋回）すると、掴まり状態の安定性を欠き、危険な場合さえも生じる。
そこで、本発明では、上記の不具合の対策手段として、二つの管材構造物の略平行に相対峙する位置の管材同士を合一に抱き込むべく、二つ平行に並んだ各ソケット部に挿入することで二つの構造物の連結を達成する構成であるが、凹溝部の形状が丸管形なので容易に管軸回りに回転し、連結した側の管材構造物１が容易に回転してしまう不具合を生ずる。
そこで、そのソケット部から繋ぎ腕部を延ばし、同繋ぎ腕部の先端部にもソケット部を設けて、前記一定の傾斜角で連なる第二の管材１２（例えば図２を参照）を、その繋ぎ腕部先端のソケットで抱持させる構成（例えば図５Ａ、Ｂなど参照）に管材連結用継手を構成したから、前記支柱支持管材１０（図２）が挿入されるソケット部の管軸回りの回転は止められる。
そして、もう一方の抱持部に連結された管材構造物２の回転を止める手段として、そのソケット部の抱持部内周面に管軸方向への平面部３１５（図３、図４参照）を設け、管材構造物２を構成する管材の外周面にも前記ソケット部の平面部３１５と合致する管軸方向への平面部２１（図１Ａ参照）が形成されている。
そして、管材構造物２を前記管材の平面部２１へ、ソケット部の抱持部内周面に形成した前記平面部３１５の位置を合わせて、この管材連結用継手３を組み付けることにより、床置き型手すり１の支柱用管材１０に対して、補助手すり２の水平方向の向きが回転しないように固定した構成で連結することができる。
こうして補助手すり２の水平方向の向きを異ならせて連結した実施態様を、図７Ａ〜Ｃに例示している。
もとより、補助手すり２の連結は、１個の限りではない。必要に応じて２個を適宜の態様で連結し組み合わせても良い。
上記の構成であるから、図８に示したように、第二の管材１２に対して並行する配置に補助手すり２を所望する水平角度、又は一定の傾斜角度に取り付けて使用の便利に供することも容易に可能である。 Next, when the auxiliary handrail 2 is connected to the support pipe 10 of the floor-type handrail 1 as described above to realize a composite aid, the auxiliary handrail 2 rotates (swivels) around the support pipe 10. ) May be convenient for some healthy users. However, on the contrary, for users who are so severe that the gait is not rough, if the auxiliary handrail 2 rotates (turns) around the support pipe 10, the gripped state is not stable and even dangerous.
Therefore, in the present invention, as a measure against the above-described problems, the pipe members at the positions where the two pipe material structures are opposed to each other in parallel are inserted into the socket parts arranged in parallel to each other so as to embrace together. This is a configuration that achieves the connection of two structures, but because the shape of the groove is a round tube, it easily rotates around the tube axis, and the connected tube structure 1 easily rotates. Is produced.
Therefore, the connecting arm portion is extended from the socket portion, a socket portion is also provided at the tip of the connecting arm portion, and the second pipe member 12 (see, for example, FIG. 2) connected at the constant inclination angle is connected to the connecting portion. Since the joint for connecting the pipe material is configured to be held by the socket at the tip of the arm part (see, for example, FIGS. 5A and 5B), the socket part into which the support column pipe material 10 (FIG. 2) is inserted is rotated around the pipe axis. Is stopped.
As a means for stopping the rotation of the tube structure 2 connected to the other holding portion, a flat portion 315 (see FIGS. 3 and 4) in the tube axis direction is provided on the holding portion inner peripheral surface of the socket portion. A flat portion 21 (see FIG. 1A) in the tube axis direction that matches the flat portion 315 of the socket portion is also formed on the outer peripheral surface of the pipe material that is provided and constitutes the pipe material structure 2.
Then, the pipe structure 2 is assembled to the flat part 21 of the pipe, the flat part 315 formed on the inner peripheral surface of the holding part of the socket part is aligned, and the pipe connection joint 3 is assembled to thereby install the floor structure type. It can be connected to the supporting pipe material 10 of the handrail 1 in a configuration fixed so that the horizontal direction of the auxiliary handrail 2 does not rotate.
An embodiment in which the horizontal directions of the auxiliary handrails 2 are connected in this manner is illustrated in FIGS.
Of course, the connection of the auxiliary handrail 2 is not limited to one. If necessary, the two may be connected and combined in an appropriate manner.
Since it is the above configuration, as shown in FIG. 8, the auxiliary handrail 2 is attached at a desired horizontal angle or a fixed inclination angle in a parallel arrangement with respect to the second pipe member 12 and provided for convenient use. Is also possible easily.

以上に図面に示した実施形態に基づいて本発明を説明したが、本発明は、図示例の実施形態の限りではない。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。
例えば、半割形状の抱持部（半割ソケット）を相互に結合する手段としては、上述したダブテール形状の凸部と凹部の組み合わせには限らない。意匠登録第１４０６１８１号に示されたような鍵型の凹凸の組み合わせ、その他の適宜な構成を採用して実施することも好ましい。 Although the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the illustrated embodiments. It should be noted that it includes a range of design changes and application variations that are usually made by those skilled in the art without departing from the technical idea thereof.
For example, the means for mutually connecting the half-shaped holding portions (half sockets) is not limited to the combination of the above-described dovetail-shaped convex portions and concave portions. It is also preferable to implement by adopting a combination of key-shaped irregularities as shown in Design Registration No. 1406181, and other appropriate configurations.
