Rehabilitation booster wheel chair
Technical field
The present invention relates to a kind of wheelchair, especially relate to a kind of simple and practical, flexible and convenient to use, function is many, safety is good rehabilitation booster wheel chair.
Background technology
Existing wheel-chair is various in style, and function also has varied, is more electric wheelchair, flexibly and easily;But electric wheelchair flexible is more also ridden instead of walk, the people used relies on a lifetime possibly, and the existing multifunctional wheelchair walked can only be push by wheelchair passively or hang and walk, so the RI of patient is had adverse effect on, and rehabilitation booster wheel chair is likely to work hard when using, but can effectively take exercise and rehabilitation health, it is possible to provide many convenience for trip, movement, life etc.;
The utility model that application number is CN200820085124.4 discloses a kind of Manual arising multifunctional wheel chair, including main support and mounting hinged successively, back rest and lower limb frame, mounting is hinged to be positioned on main support, main support arranges front and rear rolling wheel, mounting is connected with hinge-rod, the rear end of hinge-rod is hinged with back rest, locating slot and the hinged bar of leg support on front end and main support are hinged, front end pin joint is provided with locking device, one end of hinged bar is hinged with main support and mounting, the other end is hinged by toggle and leg support, one end of telescoping mechanism is hinged on main support, the other end is matched by the hinge between drive mechanism with hinge-rod, hinge end arranges attitude-adjusting system, main support is provided with lying posture controlling organization ..., the utility model that application number is CN201120404280.4 discloses a kind of multifunctional electric wheelchair, particularly relate to a kind of electric wheelchair realizing the sleeping three kinds of postures of sitting, it includes chair with back, described chair with back bottom is hinged with seat support by the first rotating shaft, described seat support bottom is hinged with gripper shoe by the second rotating shaft, described gripper shoe is hinged with by lower limb by the 3rd rotating shaft, described gripper shoe bottom is fixedly connected with chassis overhang, described chassis overhang bottom is provided with driving wheel and driven pulley;Described first rotating shaft is connected to the first angle adjustment motor, and described second rotating shaft is connected to the second adjustment motor, and described 3rd rotating shaft is connected to third angle and adjusts motor;Described chair with back and seat support, seat support and be provided with fixing plate by between lower limb ...;Although the seat that they solve patient, the translation function lain, stand, but the same with the existing wheel-chair stood is people integrally held up, rather than allow people stand up and sit down, and handrail is all in upper end (oxter people), so that the rehabilitation of both hands is also unfavorable, the forward and backward space of lower end foot is also little, and during walking, health and foot can be inconvenient, and structure is complicated;When can independently stand such as patient, electric wheel-chair vehicle when not driving motor patient because wheel-chair has a resistance cannot oneself walking, driven motor, push by wheel-chair again and can not autonomous;
I am through long-term thinking and look through a great amount of information and retrieve, and finally designs a kind of simple and practical, flexible and convenient to use, function is many, safety is good rehabilitation booster wheel chair.
