Description

本発明は玄関の段差部等に設置する介護用手摺りに関するものである。   The present invention relates to a handrail for nursing care installed at a stepped portion or the like of an entrance.
介護用手摺りは、一般の家庭用住宅における玄関の上がりカマチ等に、身体障害者や高齢者などの入居者の必要に応じて配置したり撤去することができるものであり、上がりカマチの高さ(段差)は住宅によってまちまちであるので、下記特許文献1、2等に示された介護用手摺りは、支柱が伸縮可能に構成され、該支柱を上がりカマチの高さに応じて伸縮させることにより、上がりカマチの高さがまちまちであっても配置し得るように構成したものであった。   Handrails for nursing care can be placed and removed as needed by residents such as the physically disabled and elderly people, etc. on the rising doors of ordinary homes. Since the length (step) varies depending on the house, the handrails for nursing care shown in the following Patent Documents 1 and 2, etc. are configured such that the support column can be extended and contracted, and the support column is raised and expanded according to the height of the kamachi. Thus, even if the height of the raised gusset varies, it can be arranged.
特開2012−87507号公報JP 2012-87507 A 特開2012−219613号公報JP 2012-219613 A
しかしながらこれら従来の介護用手摺りは、手摺バー(使用者が手を握る部分)の長手方向の傾斜角度を調節できるものではない。即ち、これらの特許文献に示された従来の介護用手摺りは、一体的な手摺バー全体の設定高さを上下に調節し得るだけであって、手摺バーの長手方向の傾斜角度を調節し得るものではなかったので、例えば段差が非常に大きい上がりカマチに設置した場合、上がりカマチに登ろうとする使用者は高い位置にある手摺バーを手で掴まければならず、反対に上がりカマチを降りようとする使用者は低い位置にある手摺バーを掴まければならないようになるなど、使い勝手が悪くなるという問題があった。なお、特許文献2に示された介護用手摺りでは、上がりカマチの平均的な高さに合わせて手摺バーを屈折した形状にしているが、段差の大きさは上記のように一定でないので、このような問題は未だ解消されていない。   However, these conventional handrails for care cannot adjust the inclination angle in the longitudinal direction of the handrail bar (the part where the user holds the hand). That is, the conventional handrails for care shown in these patent documents can only adjust the set height of the whole handrail bar up and down, and adjust the inclination angle of the handrail bar in the longitudinal direction. For example, when installing in a raised kerchief with a very large step, a user who wants to climb the raised gusset must grasp the handrail bar in a high position by hand, There is a problem in that the user who tries to use the handrail bar at a low position has to use the handrail, and the usability is deteriorated. In addition, in the handrail for nursing care shown in Patent Document 2, the handrail bar is refracted in accordance with the average height of the raised gusset, but the size of the step is not constant as described above. Such a problem has not been solved yet.
本発明は介護用手摺りのこのような問題点を解消しようとするもので、基板の前後位置に伸縮自在なる中間部支柱と後部支柱とを垂設し、該中間部支柱の上端に手摺バーの長手方向略中間部を第1継手を介在させることにより傾動可能に枢支し、該手摺バーの後方部と前記後側支柱の上端とを第2継手および第3継手を介して屈折可能に連結するとともに、該手摺バーの前方部に第4継手を介して伸縮自在なる前部支柱を垂下状に設けてなることを特徴とする。
また、本発明は上記介護用手摺りにおいて、手摺バーの後端部が下方にU字状に折り曲げられているとともに、該手摺バーの前方にU字形の延長手摺バーが第4継手を介して連結され、該延長手摺バーに前部支柱を垂下状に設けてなることを特徴とする。
The present invention is intended to solve such a problem of a handrail for care, and an intermediate column and a rear column that can be extended and contracted at the front and rear positions of the substrate are suspended, and a handrail bar is provided at the upper end of the intermediate column. The middle part of the rail is pivotably supported by interposing the first joint so that the rear part of the handrail bar and the upper end of the rear column can be refracted through the second joint and the third joint. In addition to being connected, a front support column that is extendable and contractible via a fourth joint is provided in a hanging shape at the front portion of the handrail bar.
According to the present invention, in the handrail for care, the rear end portion of the handrail bar is bent downward in a U shape, and a U-shaped extension handrail bar is provided in front of the handrail bar via a fourth joint. The extension handrail bar is connected and a front support column is provided in a hanging shape.
本発明に係る介護用手摺りによれば、手摺バーの傾斜角度を段差の大きさや使用者に合わせて自在に調節できるので、特に身体障害者や高齢者などにとって使い勝手が大幅に向上し、介護用品として優れたものとなる。   According to the handrail for nursing according to the present invention, the inclination angle of the handrail bar can be freely adjusted according to the size of the step and the user, so that the usability is greatly improved especially for the handicapped person and the elderly. It will be an excellent product.

次に本発明に係る介護用手摺りを図面とともに説明する。図1、図2に示すように、10は鉄板11の上面に滑止用のゴムシート12を張設してなる基板である。なお、該基板の前縁部には該鉄板を上向に折曲することによりリブ13が一体に形成されている。また、該基板10上の前方位置に左右一対の伸縮自在なる中間部支柱20が垂設され、該基板10上の後方位置に左右一対の伸縮自在なる後部支柱30が垂設される。該中間部支柱20は、伸縮自在に構成するために太径筒部材21と細径筒部材22とからなり、該太径筒部材21は、下端部を基板10上にボルト23によって固定され、該太径筒部材21の相対する側壁の下方部であって高さ方向に適宜間隔を離して複数の止孔24が開設され、摘子25が一端に形成された支軸26を該止孔24に貫挿している。また、該太径筒部材21の上方部にナット27が固着され、摘子28が一端に形成されたネジ軸29を該ナットに螺合してなる。一方、細径筒部材22は、該太径筒部材21の上端開口に摺動自在に貫挿され、前記支軸26によって該細径筒部材22の下端が支持されているとともに、前記ネジ軸29の先端を該細径筒部材22の側面に圧着することにより、該細径筒部材22の自在摺動が制止される。このため、ネジ軸29を緩めて該細径筒部材22を上下動し、複数の止孔24から支軸26を貫挿するものを適宜選択し、ネジ軸29を締めなおすことにより、該細径筒部材22の高さが自在に調節されるようになる。また、後部支柱30についても、伸縮自在に構成するために太径筒部材31中に細径筒部材32が摺動自在に貫挿され、摘子35が一端に形成された支軸を止孔34に貫挿するとともに、摘子38が一端に形成されたネジ軸をナット37に螺合してなり、中間部支柱20と同様に細径筒部材32の高さを自在に調節し得るように構成されている。   Next, the nursing handrail according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, reference numeral 10 denotes a substrate in which an anti-slip rubber sheet 12 is stretched on the upper surface of an iron plate 11. A rib 13 is integrally formed at the front edge of the substrate by bending the iron plate upward. In addition, a pair of left and right telescopic intermediate struts 20 are vertically suspended at a front position on the substrate 10, and a pair of left and right telescopic rear struts 30 are vertically suspended at a rear position on the substrate 10. The intermediate strut 20 is composed of a large-diameter cylindrical member 21 and a small-diameter cylindrical member 22 so as to be extendable and contractible, and the large-diameter cylindrical member 21 is fixed on the substrate 10 with bolts 23 at its lower end. A plurality of stop holes 24 are formed in the lower part of the opposite side walls of the large-diameter cylindrical member 21 and spaced at an appropriate interval in the height direction, and a support shaft 26 having a knob 25 formed at one end is connected to the stop hole. 24 is inserted. Further, a nut 27 is fixed to an upper portion of the large-diameter cylindrical member 21, and a screw shaft 29 having a knob 28 formed at one end is screwed into the nut. On the other hand, the small diameter cylindrical member 22 is slidably inserted into the upper end opening of the large diameter cylindrical member 21, the lower end of the small diameter cylindrical member 22 is supported by the support shaft 26, and the screw shaft By crimping the tip of 29 to the side surface of the small diameter cylindrical member 22, the free sliding of the small diameter cylindrical member 22 is stopped. For this reason, by loosening the screw shaft 29 and moving the small-diameter cylindrical member 22 up and down, appropriately selecting one through which the support shaft 26 is inserted from the plurality of stop holes 24, and retightening the screw shaft 29, The height of the diameter cylindrical member 22 can be freely adjusted. Further, the rear column 30 is also configured to be extendable and retractable, and a small-diameter cylindrical member 32 is slidably inserted into a large-diameter cylindrical member 31, and a support shaft having a knob 35 formed at one end is provided as a hole. 34, and a screw shaft having a knob 38 formed at one end thereof is screwed into the nut 37 so that the height of the small-diameter cylindrical member 32 can be freely adjusted in the same manner as the intermediate column 20.

そして、中間部支柱20の上端、即ち、細径筒部材22の上端部に第1継手41を設け、該第1継手を介して手摺バー50の長手方向略中間部51を枢着することにより該手摺バー50が傾動可能に支持される。なお、該第1継手41は、図3に示したように、一対の継手部材40a,40bの相対する半円柱状部分に枢軸40cを貫挿することにより該継手部材40a,40bを該枢軸40cと直交する方向に回転可能に連結してなるもので、該各継手部材40a,40bの基部を細径筒部材22の上端部および手摺バー50に形成された連結部52に嵌着固定することにより該手摺バー50を傾動可能に支持し得る。   And the 1st coupling 41 is provided in the upper end of the intermediate | middle part support | pillar 20, ie, the upper end part of the small diameter cylindrical member 22, and the longitudinal direction substantially intermediate part 51 of the handrail bar 50 is pivoted through this 1st coupling. The handrail bar 50 is supported to be tiltable. As shown in FIG. 3, the first joint 41 inserts the pivot 40c into the opposing semi-cylindrical portions of the pair of joint members 40a and 40b, thereby connecting the joint members 40a and 40b to the pivot 40c. The bases of the joint members 40a and 40b are fitted and fixed to the upper end of the small-diameter cylindrical member 22 and the connecting portion 52 formed on the handrail bar 50. Thus, the handrail bar 50 can be supported to be tiltable.
また、手摺バー50の後方部と後側支柱30の上端とを図3に示した第1継手41と同じ構造の第2継手42および第3継手43を介して屈折可能に連結している。即ち、後部支柱30の上端である細径筒部材32の上端部に第2継手42の一方の継手部材を嵌着固定し、該第2継手42の他方の継手部材に筒状の短支柱53を嵌着固定し、該短支柱53の上端部にさらに第3継手43の一方の継手部材を嵌着固定し、該第3継手43の他方の継手部材に手摺バー50に形成された連結部54に嵌着固定している。これにより手摺バー50の後部を後部支柱30の上端部に第2継手42および第3継手43を介して屈折可能に連結してなる。なお、手摺バー50の後端部55は、手で掴み易いように下方にU字状に折り曲げられている。57はエンドキャップである。   Further, the rear portion of the handrail bar 50 and the upper end of the rear column 30 are connected to be able to be bent through the second joint 42 and the third joint 43 having the same structure as the first joint 41 shown in FIG. That is, one joint member of the second joint 42 is fitted and fixed to the upper end portion of the small-diameter cylindrical member 32 that is the upper end of the rear column 30, and the cylindrical short column 53 is fixed to the other joint member of the second joint 42. And a joint member formed on the handrail bar 50 on the other joint member of the third joint 43. 54 is fixedly fitted. Thus, the rear portion of the handrail bar 50 is connected to the upper end portion of the rear column 30 so as to be able to be refracted through the second joint 42 and the third joint 43. The rear end portion 55 of the handrail bar 50 is bent downward in a U shape so that it can be easily grasped by hand. 57 is an end cap.
一方、手摺バー50の前方にはU字形の延長手摺バー56が図3に示した第1継手41と同じ構造の第4継手44を介して連結され、該延長手摺バー56の端部に伸縮自在なる前部支柱60が垂下状に連結される。該前部支柱60は、該延長手摺バー56の下端部に固設された太径筒部材61と、該太径筒部材の下端開口に摺動自在に貫挿された細径筒部材62とからなり、該太径筒部材の一側壁にナット63が固着され、摘子64が一端に形成されたネジ軸65を該ナットに螺合することにより該ネジ軸65の先端で該細径筒部材62を圧着し該細径筒部材62が支持されるようにしている。66は該細径筒部材62の下端部に止着された弾性覆部材である。   On the other hand, a U-shaped extension handrail bar 56 is connected to the front of the handrail bar 50 via a fourth joint 44 having the same structure as the first joint 41 shown in FIG. A free front strut 60 is connected in a drooping manner. The front column 60 includes a large-diameter cylindrical member 61 fixed to the lower end of the extension handrail bar 56, and a small-diameter cylindrical member 62 slidably inserted into the lower end opening of the large-diameter cylindrical member. A nut 63 is fixed to one side wall of the large-diameter cylindrical member, and a screw shaft 65 having a knob 64 formed at one end is screwed into the nut, whereby the small-diameter cylinder is formed at the tip of the screw shaft 65. The member 62 is pressure-bonded so that the small-diameter cylindrical member 62 is supported. Reference numeral 66 denotes an elastic covering member fixed to the lower end portion of the small diameter cylindrical member 62.
このように構成した介護用手摺りは、図4に示したように、前記リブ13が上がりカマチ70の起立部に当たるように基板10を玄関に置いて、手摺バー50の後端部55が使用者の身長に合わせて使い易い高さに調整されるように後部支柱30を前述のように伸縮させるとともに、手摺バー50の中間部および前方の手摺バー56も使用者の身長に合わせて使い易い高さに調整されるように中間部支柱20を伸縮させる。このとき、手摺バー50は第1継手41を介して中間部支柱20に支持されているとともに第2継手42および第3継手43を介して後部支柱30に支持されているので、図5に例示したように、これらの継手により屈折が自由になることから、該手摺バー50の長手方向の傾斜角度を必要に応じて自由に設定することができる。そして、該手摺バー50の傾斜角度をこのように変えても、手摺バー56を第4継手44で屈折させることで前部支柱60を上がりカマチ70の上に常に垂直に垂下させられ、該細径筒部材62の下端部弾性覆部材66を該上がりカマチ70上に接触させた状態で摘子64を締めてネジ軸65により該細径筒部材62を不動に圧着することにより、手摺バー50および延長手摺バー56を前部支柱60に安定的に支持することができる。このようにこの介護用手摺りは、使用者にとって常に使い勝手が良いように傾斜角度を自由に設定することができる。   As shown in FIG. 4, the nursing handrail constructed in this way is used with the rear end portion 55 of the handrail bar 50, with the substrate 10 placed at the entrance so that the rib 13 rises and hits the standing portion of the kerchief 70.

The middle support column 20 is expanded and contracted so as to be adjusted to the height. At this time, the handrail bar 50 is supported by the intermediate column 20 through the first joint 41 and supported by the rear column 30 through the second joint 42 and the third joint 43. As described above, since refraction is freed by these joints, the inclination angle in the longitudinal direction of the handrail bar 50 can be freely set as necessary. Even if the inclination angle of the handrail bar 50 is changed in this way, the front column 60 can be lifted by the fourth joint 44 to refract the handrail bar 56 so that the handrail bar 56 is always vertically hung down on the kerchief 70. By tightening the knob 64 with the lower end elastic covering member 66 of the diameter cylindrical member 62 being in contact with the raised gusset 70, the small diameter cylindrical member 62 is fixedly crimped by the screw shaft 65, whereby the handrail bar 50 In addition, the extended handrail bar 56 can be stably supported by the front column 60. As described above, the care handrail can freely set the inclination angle so that it is always convenient for the user.
そして、この介護用手摺りは、中間部支柱20と後部支柱30と前部支柱60とによって手摺バー50、延長手摺バー56が安定的に支持されるので、十分な強度が得られ、安全に使用できるとともに、該手摺バー50の傾斜角度を自由に設定することができるので、上がりカマチ等の段差の大小に応じて常に的確な対処ができ、身体障害者や高齢者など使用者が使い易いものとなる。また、この介護用手摺りは、中間部支柱20および後部支柱30が基板10上に支持されているので、必要に応じて設置や撤去を極めて容易に行うことができる。   In this handrail for care, the handrail bar 50 and the extended handrail bar 56 are stably supported by the intermediate column 20, the rear column 30 and the front column 60, so that sufficient strength can be obtained and it can be safely performed. In addition to being usable, the inclination angle of the handrail bar 50 can be freely set, so that it is possible to always deal accurately with the level of the stepped portion such as a raised gusset, and it is easy to use for users such as the physically handicapped and the elderly It will be a thing. Moreover, since the intermediate | middle part support | pillar 20 and the rear part support | pillar 30 are supported on the board | substrate 10, this nursing handrail can be installed and removed very easily as needed.
また、この介護用手摺りは、手摺バー50の後端部が下方にU字状に折り曲げられているとともに、該手摺バーの前方にU字形の延長手摺バー56が第4継手44を介して連結されているので、手摺バー50の後端部および前方端部を手で掴み易くすることができ、この点でも使い勝手が良い。
なお、この実施形態は、左右一対の手摺バーからなる両側手摺りについて説明したが、本発明の機構は片側手摺りにもそのまま適用することができる。
The nursing handrail has a rear end portion of the handrail bar 50 bent downward in a U-shape, and a U-shaped extension handrail bar 56 is provided in front of the handrail bar via a fourth joint 44. Since they are connected, the rear end portion and the front end portion of the handrail bar 50 can be easily grasped by hand, and this is also convenient for use.
In addition, although this embodiment demonstrated the both-sides handrail which consists of a pair of left and right handrail bars, the mechanism of the present invention can be applied to a one-side handrail as it is.
