Description

【0001】
【発明の属する技術分野】
本発明は安全を優先とする手摺り装置に関する。
【0002】
【従来の技術】
転倒防止や体位保持に有効な手摺り装置は、手指を用いて手摺り部を把握することにより、その効果が活用される。したがって把握の滑りが転倒等による大きな事故因となる。近時社会の高齢化と共に手摺り設置場所(廊下・階段・風呂場等)での事故が増加している。また楕円・扁平形状手摺りは強度に問題がある。
【0003】
【発明が解決しようとする課題】
手摺り利用の実態調査によれば、利用者のほとんどが手摺り上面に5指を並べて近接または軽く接触させて移動(手を摺らす)している。したがって突然的に足が滑ったりつまづいたりして体位のバランスが崩れた場合、瞬時に親指を手摺り上面部から下面部に移動させ親指と他の4指間で強力な把握(掌握)を行なうには短いながら時間を要するので、その間に生ずる身体側からの腕引き応力に対応するには先ず親指以外の4指で支えようと4指の反射的曲げ運動(反応)が生ずる。したがってこの短時間内(瞬時)に4指と手摺り部との間に滑り作用が生ずれば把握に到るまでに手指が脱離し体位を支持することができなく転倒することにもなる。この場合手摺り面に水分、石鹸分等が付着している場合は滑り性は更に大となり危険度も増加することから、より安全な手摺り構造が求められる。
【0004】
【課題を解決するための手段】
本発明は体位保持に有効な手摺り構造として、先ず体位の崩れが生じた場合(足の滑りやつまづき転倒等)、脳よりの危険指示に最も敏感に反応する指先の捕まり曲げ握り行為動作を利用し、手摺り部の指先方向端に曲げた4指部が鉤の手状に掛かり得るよう指掛部を形成することにある。この瞬時的4指の指曲げ握り動作と手摺り部への指掛け作用によれば、4指が滑りによって手摺りより脱離する現象を指関節の曲げ作用によって一時的に抑止し得るので、次に親指を下部に廻し確実な・強力な把握の条件が短時系で構成され、体位保持の目的を達成することができる。更に長手方向の滑り止め対策として手摺り表面の一部または全部に突状部を鍔状・節状に設けることや、指掛用凹凸部を区画的に構成することにより手摺り利用者が掌掛かり・指掛かりを接触感によって認識せしめることとしている。また別の例では指掛部を下部方向としリハビリ用平行棒に用いた場合、上部よりの腕の支えと応力に対し従来の円曲面より平面部を有する図2の構造が手掌部の加圧分布に無理なく4指の運動も行ないやすいことからリハビリ用に適した構造である。
【0005】
【発明の実施の形態】
本発明の実施例を図について説明すると次のごとくである。図1に示すごとくに構成された手摺りによれば体位確保に必要な手摺りの把握条件である親指を活用した握り作用に到るまでの間に他の4指が滑り把握の機会を失うことのないように先ず本能的な脳よりの危険指示に最も速く反応する4指の曲げ作用を利用し、この滑りを抑制する鉤状指関節形状と指掛部形状との相関によって瞬時的に指滑りを防止するものである。したがってその間に親指での把握条件(親指が手摺り上面から下面まで移動する時間的条件)が成立し、体位保持のために必要な確実な親指活用の把握が咄嗟の場合でも行ない得るのである。手摺り設置場所における転倒事故は年々増加しており、その原因のほとんどは手摺りが滑ったり、そのため把まり損なって転倒したり、いずれも把握行動の遅れによる結果が原因で事故因となることが多い。また転倒による事故は骨折等に繋がる場合が多く、本人の苦痛は当然ながらそれが寝たきり患者へと進行し、治療費のみならず本人・家族の経済的精神的負担は想像を遥かに越える結果ともなり、周辺関係者の人生をも変えてしまう結果を招くのである。
特に高齢社会では手摺りは生活の安全を保守するためには絶対的・常識の範疇で必需設備であるが、現商品の機能はマンネリ化した形状が多く、真の役割目的を重視研究されたものは皆無である。因って今日の手摺り技術を見直し万人の安全を向上すべきより有効有益なる手摺りの新技術が必要である。
【0006】
【作 用】
このことは手摺りパイプ円径が大きい程また水分や石鹸分が付いていることでも滑り作用の大きくなることが理解できる。本発明においては図1に示すごとき外郭線断面構造によりバランスの崩れる咄嗟の場合、最も速く反応しうる4指の指掛け作用で先ず手の離脱を防ぎ、更に親指を活用した確実な把握動作に移行しうる安全な手摺り構造とその作用過程を説明し対応技術を提示したものである。
【0007】
【発明の効果】
本発明の手摺り構造によれば多発している手摺りの握り損ない(遅れ)と滑りにより手離れ(滑落)原因の事故が抜本的に改善され、転倒により怪我や事故が減少することになる。したがって国民の健康と介護・医療等経済に資すること絶大な技術である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a handrail device that gives priority to safety.
[0002]
[Prior art]
A handrail device that is effective in preventing a fall and maintaining a body position utilizes its effect by grasping a handrail portion using fingers. Therefore, slippage in grasping may cause a large accident due to a fall or the like. With the recent aging of society, accidents at handrail installation locations (corridors, stairs, bathrooms, etc.) are increasing. Elliptical / flat handrails have a problem in strength.
[0003]
[Problems to be solved by the invention]
According to a survey on the use of handrails, most of the users move (slide their hands) by arranging five fingers on the upper surface of the handrail and making close or light contact. Therefore, if your feet suddenly slip or stumble, and your balance is lost, you can instantly move your thumb from the top to the bottom of the handrail to obtain a strong grip between your thumb and the other four fingers. Since it takes a short time to perform, a reflex bending movement (reaction) of the four fingers occurs to support the four fingers other than the thumb first in order to cope with the arm pulling stress generated from the body side during that time. Therefore, if a sliding action is generated between the four fingers and the handrail portion within this short time (instantaneous), the fingers are detached and the body cannot be supported and fall down before grasping. In this case, if moisture, soap, or the like is attached to the handrail surface, the slipperiness is further increased and the risk is increased, so that a safer handrail structure is required.
[0004]
[Means for Solving the Problems]
The present invention provides a handrail structure that is effective for holding the body position. First, when the body loses its position (eg, slipping of the foot or stumbling over), the fingertip is most sensitive to the danger instruction from the brain. The finger hook is formed so that the four fingers bent to the fingertip direction end of the handrail can be hooked in the shape of a hook. According to the instant four-finger finger bending and gripping operation and the finger-holding action on the handrail portion, the phenomenon that the four fingers detach from the handrail due to slippage can be temporarily suppressed by the bending action of the finger joint. The thumb is turned to the lower part, and the conditions for reliable and strong grasping are configured in a short time system, and the purpose of maintaining the posture can be achieved. Further, as a measure to prevent slippage in the longitudinal direction, a protrusion is provided in a part or the whole of the handrail surface in a flange shape or a knot shape, and a handhold user can control the handrail by forming a finger-shaped uneven portion in a partitioned manner. It is designed to make it possible to recognize hooking and finger hooking based on a sense of contact. In another example, when the finger hook portion is directed downward and used as a parallel bar for rehabilitation, the structure of FIG. The structure is suitable for rehabilitation because it is easy to move four fingers easily.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings as follows. According to the handrail configured as shown in FIG. 1, the other four fingers lose the opportunity to grasp the handrail before reaching the gripping action utilizing the thumb, which is the condition for grasping the handrail necessary for securing the body position. First, use the four-finger bending action that responds fastest to danger instructions from the instinct brain, and instantaneously uses the correlation between the hook-like finger joint shape and finger hook shape that suppresses this slip. It prevents finger slippage. Therefore, the condition for grasping with the thumb (the time condition for the thumb to move from the upper surface to the lower surface of the handrail) is established in the meantime, and it is possible to reliably grasp the utilization of the thumb necessary for maintaining the body position even in an immediate case. Fall accidents at handrail installation locations are increasing year by year, and most of the causes are that the handrails slip or fall off due to poor grasping, and both are the causes of accidents due to delays in grasping behavior There are many. In addition, accidents due to falls often lead to fractures, etc., and the suffering of the patient naturally progresses to bedridden patients, and not only the cost of treatment but also the financial and psychological burden of the patient and his family far exceeds imagination. It can also change the lives of those involved.
Especially in an aging society, handrails are essential equipment in the category of absolute and common sense in order to maintain the safety of life, but the functions of current products are often in the form of a rut, and research was conducted with emphasis on the true role purpose Is nothing. Therefore, there is a need for new and more effective handrail technology that should review today's handrail technology and improve the safety of all.
[0006]
[Operation]
It can be understood that the larger the diameter of the handrail pipe is, the greater the sliding action is due to the presence of moisture and soap. In the present invention, in the case of imbalance due to the outline cross-sectional structure as shown in FIG. 1, the quickest reaction of the four fingers can prevent the detachment of the hand and shift to the reliable grasping operation utilizing the thumb. It describes a safe handrail structure that can be used and its working process, and presents a corresponding technology.
[0007]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the handrail structure of this invention, the accident of the handrail (sliding down) caused by frequent gripping loss (delay) and slippage of the handrail is drastically improved, and injuries and accidents due to falling are reduced. . Therefore, it is an enormous technology that contributes to the health of the people and the economy such as nursing care and medical care.
