Abstract
A wheelchair with the automatic regulation of center of gravity relates to a chair or wheelbases vehicle that is specially applied to the weak and sick people, in particular to a wheelchair with the automatic regulation of center of gravity. The utility model provides a wheelchair with the automatic regulation of center of gravity, thus keeping the balance of the seat cushion. The utility model is provided with a frame, a seat cushion, a back cushion, a side board, a handrail, a handle, a small wheel and its bracket, a big wheel, a hinge chain, a pushing circle, a brake device, a pedal plate and a foot pipe, wherein the left and right sides at the bottom of the seat cushion are provided with at least two wheels, on the brackets which connect with the left and right sides at the bottom of the seat cushion are provided with concave arc sliding grooves respectively, and the wheels on the left and right sides at the bottom of the seat cushion can be placed in the arc sliding grooves for rolling at ease. The seat cushion can slide easily along the lower concave arc sliding grooves on the brackets, when meeting with the up-and-down hills, obstacles, getting into and getting out of the cars or parking, the utility model can regulate the center of gravity within a certain scope stably at any time, thereby preventing the phenomena of lean back, lean forward or sloshing of the body to a large extent and keeping the physical balance better, which is safe and comfortable.
Description
Technical field
This utility model relates to a kind of weakling's of being specially adapted for chair or many wheelspans car, especially relates to a kind of wheel Wheel-chair that can regulate center of gravity automatically.
Background technology
The wheel Wheel-chair is the old,weak,sick and disabled and handicapped person's an important walking-replacing tool, and publication number has been for the patent of invention of CN1185311A provides a kind of wheel Wheel-chair that can stair activity, takes off formation carriage such as nut with speed and makes Wheel-chair can keep accurate level; Being obstructed in longfoot wheel (chain shoe) front can be smooth with wheel (chain shoe), oppositely is subjected to resistance to increase the cat ladder contact surface again, contact height, length and increase retardance downslide dynamics.Publication number provides a kind of accessible Wheel-chair of taking turns voluntarily for the utility model patent of CN2580934Y, is fit to level walking and climbs minor grade, and it also has four spider wheels, is fit to climb step.The power of right-hand man's rocking handle, by about three chain rings and the transmission of four axle side rings power is reached left and right sides rubber tire.Left and right sides chain is a separate transmission, and rubber tire advances or turns operation freely.The moving pull bar of plate lifts left and right sides rubber tire and universal guide wheel by connecting rod and leverage, simultaneously seat inclination semireclining shape when climbing step.Publication number provides a kind of multipurpose combined Wheel-chair of taking turns for the patent of invention of CN1511507A, is made up of cantilever chair, trailing wheel molectron, front wheel assembly, pull bar, screw; Cantilever chair includes seat support, the chair back, handrail and chair support and forms, the trailing wheel molectron includes the wheel that a pair of correspondence has minor axis, a pair of correspondence is led the rosette of pipe sleeve, front wheel assembly includes pedal, front-wheel, front fork, the slotting frame of pedal, and pull bar is designed to the walking stick shape.
According to manual pulley Wheel-chair standard GB/T13800-92, general its static stability of wheel Wheel-chair is vertically 〉=10, and slope stability 〉=8 are stayed in side direction 〉=15, be applicable to that the room is inside and outside, lawn and flat road surface, when user gets on and off or stops, utilize brake to play stability action.And existing seat cushion (or seat support), backing cushion and other plate of taking turns Wheel-chair is general and vehicle frame fuses, because during actual the use, can not satisfy its service condition fully, when user runs into upward slope, descending, barrier, gets on the bus, gets off and when stopping, center of gravity changes, cause health significantly to swing back, lean forward or rock, cause dangerous and uncomfortable easily.
Summary of the invention
The purpose of this utility model is to fuse at existing seat cushion (or seat support), backing cushion and other plate and vehicle frame of taking turns Wheel-chair, when the wheel Wheel-chair runs into that upward slope, descending, barrier and user are got on or off the bus and when stopping, cause mass centre changing, health is swung back significantly, is leaned forward or rocks, user is caused danger and uncomfortable defective easily, provide a kind of and can regulate center of gravity automatically, make seat cushion keep the equilibrated Wheel-chair of taking turns.
This utility model is provided with vehicle frame, seat cushion (or seat support), backing cushion, other plate, handrail, handle, steamboat and little wheel support, bull wheel, hinge, promoting ring, brake gear, pedal and step pipe, present rebasing left and right sides is respectively equipped with at least 2 rollers, be respectively equipped with arcs of recesses sliding tray down on the support that the left and right sides is connected bottom seat cushion, the roller of the left and right sides, seat cushion bottom places in the arc sliding tray and can roll freely.
The rear and front end of infra arcs of recesses sliding tray preferably is provided with locating part, so as the rolling scope of restriction seat cushion, roller, the safety of assurance user.The set roller in described present rebasing the left and right sides respectively is 3 about preferably.
Because seat cushion can roll freely along the following arcs of recesses sliding tray on the support, therefore running into upward slope, descending, barrier, getting on the bus, get off or when stopping when user, can in certain scope, adjust center of gravity reposefully at any time, the phenomenon that health is swung back significantly, leaned forward or rocks can not take place, keep one's balance preferably, both safety was comfortable again.And other structures of taking turns Wheel-chair can change, and still keep other functions of use of existing wheel Wheel-chair, for example take turns the expansion of Wheel-chair and fold the adjusting of pedal, the use that push handle pipe folding turns over, the adjusting of headrest, backrest angle, hanging feet pipe etc.Obviously, compare, the utlity model has outstanding substantive distinguishing features and practical function with the existing Wheel-chair of taking turns.
