Description

Portable folding wheel Wheel-chair

Technical field

This utility model relates to a kind of Wheel-chair of taking turns, but especially a kind of fast folding or open, can be with carrying the hand push lightweight wheel Wheel-chair of taking on the body.

Background technology

Society goes up general fully collapsible invalid's chair and all adopts plane gathering form at present, though the wheelchair of this form uses extensively, but because of reasons such as its corresponding floor space and weight, use the wheelchair person for need, go out or take various vehicles aspect still to have many inconvenience whenever and wherever possible, this utility model will solve above-mentioned deficiency exactly.

Summary of the invention

The purpose of this utility model provides a kind of vertical centre gathering to the wheel chair seating face and is folded into pencil, and floor space is littler, and novel structure is light, and the portable folding that thing is gone, travels and pushed away to convenient seat to be needed is taken turns Wheel-chair.

The novel technical scheme of taking of this utility model is:

By two every group, totally four groups of each vertical planes at the hinged support beam tube of interstitial chiasma and eight beam tube seats are hinged respectively, and form the supporting frame of fully collapsible invalid's chair jointly with the fastening formula foot-driven lever of the locating rod of forward and backward vertical rod, rear lower, preceding bottom;

Article two, preceding vertical rod is the empty boasting formula structure that rod tube is nested, the wheel chair handle that the upper end of vertical rod fixedly turns to for the radial type sleeve pipe after two;

The seat and back cushion of high strength cloth is sleeved on four the beam tube seat surfaces and forward and backward vertical rod above the supporting frame.

Four base insteps of supporting frame are equipped with two universal front-wheels and two directed trailing wheels respectively.

The whole Wheel-chair of taking turns collapses with the vertical center line of seat cushion face or opens.

This utility model and common folding seat different good effects be: 1. whole wheelchair draws in to the vertical centre of seat and is folded into pencil, and floor space is littler, convenient little spatial placement and go out to carry; 2. advance and deflecting roller is steamboat footpath for four, weight is lighter, and the implementation that is suitable for various uses is used; 3. adopt the bundle pipes folding mode, folding rate is faster, use is more easy and convenient.

The specific embodiment

This utility model primary structure and operation principle are:

Eight folding beam tubes are by four groups of every group of two branches, and at separately the central point cross-articulation four sides that is placed in, the cross point, center of per two pipes connects with rivet to be made it freely to rotate mutually, four ends of two pipes are hinged with a vertical plane of four beam tube seats (each two up and down) respectively, make it all to rotate on tube seat plane; Each beam tube seat has orthogonal two planes, hinged with a coordination end (last or following) of two beam combination pipes respectively with rivet, each plane of each termination of four groups of cross-articulation beam tubes 9,14,18,19 and 8 beam tube seats (each 4 up and down) is hinged respectively, forms a positive sphenoid that can freely actuate.Four bases of tetrahedron lower end are loaded onto two groups of different wheels in wheel footpath respectively by the two sides, front and back, two universal steamboat footpath front-wheels 13 capable of free rotation are contained on the base 11 and front fork 12 of below, beam tube tetrahedron front, the bull wheel footpath trailing wheel 7 of two orientations (front and back rectilinear direction) is contained on the base 6 of below, beam tube tetrahedron back the hinged respectively back that is contained in two trailing wheel bases 6, the two ends of locating rod 8.When beam tube drew in, two sections hinged rivets around the center of locating rod 8 collapsed, and when beam tube opened, two sections of locating rod 8 around hinged rivet flare up linear and self-locking, kept the location of beam tube tetrahedron and wheelspan.Fastening formula pedal stroke 15 is worn by the bayonet lock at its two ends on the clamp 17 that is stuck in preceding bottom nozzle front, and the stage casing of pedal stroke 15 links to each other with high-intensity nylon cloth seat cushion 2 with drawstring 16.Two preceding vertical rods 10 of wheel Wheel-chair are the empty boasting formula, promptly two sections rod tubes are nested, see Fig. 2, wherein, article two, seat bar 24 usefulness locking nuts 25 are installed on respectively on two bottom nozzles 26 in front of front-wheel fork shaft 27, and two 22 of oriented tube are installed on two of fronts respectively and go up on the base 21, and two seat bars 24 are in guide pin bushing 23 is inserted in two oriented tube 22 respectively, when the wheel Wheel-chair actuated, the seat bar moved up and down in oriented tube.Article two, after vertical rod 4,35 separately an end pass next two respectively and go up bases and assemble with the bottom nozzles of back are fixing, the upper end of vertical rod 4 is left and right handle 3,1 after every, be fixedly connected with rivet 34 with handgrip elbow 33 1 ends respectively, the elbow other end and handle stem 30 1 ends are 32 hinged with shipping and reselling on another market, when handle stem goes to back vertical rod vertical direction, push sleeve pipe 29 to the elbow end by handle stem 30 ends and by hoodle 28 location, making hand-pushing handle and elbow fastening is working condition; When wheel Wheel-chair when collapsing, only need head into hoodle the sleeve pipe pusher is removed constraint to handle stem 30 to grip 31 positions, Fig. 3 is seen in 30 foldings downwards of handle stem.

Nylon cloth seat, back cushion comprise direct seat cushion 2 and handrail back cushion 5,20, directly four angles of the seat face of seat cushion 2 are processed with four holes (one hole, every angle), the both sides of back cushion back respectively are processed with a logical cover, cover for seat pad two holes in front are fixedly connected in front two with preceding gland and go up bases, latter two hole is then passed vertical rod 4 after two respectively and is leaned against on next two faces of going up bases, and the logical cover of seat cushion posterior dorsal then is set in the vertical rod 4 of back and is screwed; The front of two handrail back cushions 5,20 is inserted in positive two upper ends that beam tube stretches out of wheelchair respectively, and is screwed, after the back then is inserted in two respectively in the vertical rod 4; When the intersection beam tube at four sides opened, nylon cloth formed seat cushion 2, can sit the people, can hold in the palm thing; When beam tube drew in, nylon cloth then drew in gesture is flexible.See Fig. 4.With the wheelchair that draws fasciculation in the haversack of packing into, can carry on the back easily and take or place.
