起立補助車椅子乃至起立椅子の操作及び利用者の作業性と起立補助乃至横臥可変式昇降装置に関するものである。  The present invention relates to an operation of a standing auxiliary wheelchair or a standing chair and workability of a user and standing assistance or a recumbent variable lifting device.

従前の車椅子は、主として前後左右の移動に関しての利便性乃至その安全性を主体に考案され、電動走行及び着座の昇降など改良が行われているが、着座の状態で座位を上下昇降させ目線の位置をやや換える程度で、横臥することも間々ならず従前にある基本的な構造となっていた。  Conventional wheelchairs have been devised mainly for convenience and safety related to forward / backward and left / right movements, and improvements such as electric running and raising / lowering seating have been made. The position was slightly changed, and lying on the floor was a basic structure.

従前の起立椅子は、利用する者の体形及び不自由度による、利用者の姿勢に応じて適した補助が成されておらず、最も適当な高さへの変更、若しくは前倒れを抑える装備が、潤沢になされていない等、課題を残していた。（例えば、特許文献１参照）  Conventional standing chairs are not equipped with appropriate assistance according to the posture of the user, depending on the user's body shape and degree of inconvenience, and are equipped with equipment that suppresses the change to the most appropriate height or forward tilt There were still problems, such as not being made abundantly. (For example, see Patent Document 1)

介護者乃至介助者にとって、車椅子から降ろしてベットに寝かせたりするのは、介護者乃至介助者にとって体力的負担のきわめて大きい作業となっているにも拘わらず、搭乗者の負担も大きく、特に上肢に負担が大きくかかるなど、課題を残していた。（例えば、実用新案文献１参照）  For a caregiver or caregiver, getting off a wheelchair and laying it in a bed is a work that places a heavy physical burden on the caregiver or caregiver, but the burden on the passenger is particularly high. There were still issues such as a heavy burden on the company. (For example, see Utility Model Document 1)

福祉や介護の分野では、従来より介護者乃至介助者の体力的負担を、軽減するための種々の装置や道具が考案されているが、下肢不自由者が社会生活するうえで、家庭内、或いは、職場の高い所のものに手が届かないなど、限界があり起立位状態によっては、滑り落ちることや前倒れしてしまうことなど、真に利用者の要求を満たすには至っていない。（例えば、特許文献２参照）  In the field of welfare and nursing care, various devices and tools have been devised to reduce the physical burden on caregivers or caregivers. Or, there is a limit such as not being able to reach high places in the workplace, and depending on the standing position, it does not really meet the user's request such as sliding down or falling forward. (For example, see Patent Document 2)

前述した、従前の車椅子は、主として自力走行のできる搭乗者の使用に利便性が配慮された機構の車椅子で、体力の弱い人や、下肢不自由者乃至脊椎損傷事故による下半身麻痺障害者など、家庭や職場の、高い位置にある必要な物をとること等、適宜それに応じた介助をする必要があった。又、要介護者の、移行作業は介護者の大きな労力を必要とし腰痛乃至ギックリ腰などは、深刻で家庭での介護乃至介助は、すこぶる困難となっていた。  The above-mentioned conventional wheelchair is a wheelchair with a mechanism that considers convenience mainly for passengers who can run on their own, such as those with weak physical fitness, lower limbs disabled persons or persons with lower body paralysis due to spinal injury accidents, etc. It was necessary to provide appropriate assistance, such as taking necessary items at a high position in the home or workplace. In addition, the shift work of the care recipient requires a large amount of labor of the caregiver, and back pain or back pain is serious and care or assistance at home has been extremely difficult.

従前の起立補助車椅子は、座板を起立させてゆく場合、座板に対する着座者の着座位置は、固定的なものではなく、座板の傾きが増すに連れて臀部の前方向に重心は移動し、臀部を前方へ押し出されるようになるので、やがて滑りが起こるので、そのため着座者は後ずさり乃至立ち上がり動作と共に、前方へ歩み出る必要があるということであるので、慣れない者にとっては、一層危険性を増すものであった。  In the conventional stand-up support wheelchair, when the seat plate is raised, the seating position of the seated person with respect to the seat plate is not fixed, and the center of gravity moves in the forward direction of the buttocks as the tilt of the seat plate increases. However, since the buttock will be pushed forward, slipping will eventually occur, which means that it is necessary for the seated person to step forward with back-and-forth movement, which is more dangerous for those who are not used to it. It was an increase in the nature.

この起立補助椅子においては、使用者が姿勢変化の過程において前方へ、ずり落ちることなく、より安心して使用できることが要求されている。  In this standing assistance chair, it is required that the user can use it more safely without sliding down forward in the process of posture change.
