Abstract

The utility model belongs to a wheeled vehicle driven by a person sitting on the chair, and provides a wheelchair for a disabled person, which is mainly composed of a vehicle body, a seat chair and a transmission mechanism. The utility model is characterized in that the rear end of the main skeleton frame of the vehicle body is provided with a telescopic skeleton frame, and an adjusting screw rod which can adjust the length of the vehicle body is arranged between the main skeleton frame and the telescopic skeleton frame; both sides of the telescopic skeleton frame are provided with folding support frames; a rear wheel frame and a rear wheel are moved forwards following the support frame to lean on both sides of the vehicle body. The volume of the wheelchair is reduced; the seat chair is designed as a folding seat chair, a chair seat and a chair back can be attached together, and the chair seat can be separated from the vehicle body. Thus the utility model is convenient for collection and conveyance, and the length of the vehicle body can be adjusted according to the height of a user.

Description

Wheelchair capable of folding and adjusting vehicle's body length

The utility model belongs to the wheeled car that rider drives.

It is the requisite walking-replacing tool of lower limb the disabled that the disabled person takes turns car, the wheel car only can be applicable to in-plant use, if meet the long journey of long distance, then still need by means of other vehicle carryings, and taking turns car, existing disabled person all is designed to fixed sturcture, can't fold, cause collection or carrying very inconvenient.Moreover everyone stature height is also inequality, is designed to fixed and the disabled person takes turns the car bassinet structure.Therefore, can't cooperate the people of different heights to use.

Existing folding tricycle (Chinese patent 87211756) provides a kind of folding three-wheel vehicle configuration, it is provided with a folding stand that can reduce body width, the fold mechanism of this vehicle frame is made up of edge-on bar (01), middle vertical rod (02), lower link (03) and (04) four connecting rod of top rod, is a vertical direction fold mechanism.When four connecting rods shrink downwards, vehicle body and trailing wheel closing to the inside (referring to Figure 11).When this folding mode disadvantage is folding tricycle, must lift vehicle body, four connecting rods could fold downwards, otherwise can't finish jackknife action.In addition, this folding tricycle is not suitable for disabled person's use.Must improve the structure that existing disabled person takes turns car, design the three-wheel vehicle that is suitable for disabled person's use.

The purpose of this utility model is to provide a kind of wheel car of folding disabled person's use, and the bodywork length of this car can be adjusted, and uses with the disabled person who is adapted to different heights.

Below in conjunction with embodiment shown in the drawings, the technological means and the structure thereof of this creation described.

As Fig. 1, shown in Figure 4, embodiment of the present utility model---a kind of disabled person who mainly is made of car body, seat and transmission device takes turns car, wherein, the main framing of this car body (1) front end is provided with a front wheel carrier (11), is equipped with a front-wheel (12) and a handlebar (13) on the front wheel carrier; Seat is a framework frame made from steel pipe, outer again coating canvas is formed, it contains the chair back (6) and seat support (6A), the chair back and seat support can fold, the bottom surface of seat support respectively is provided with an intubate (64) for four jiaos, and seat can be integrated as an integral body with car body, it is characterized in that: there is a flexible skeleton (2) main framing of this car body (1) rear end, between main framing and flexible skeleton, be provided with one and adjust screw rod (21) and nut (22), be used for adjusting the length of car body; Front and back ends in the both sides of flexible skeleton respectively has one (3) to be connected a support (4), and this support is connected with the rear wheel frame that has trailing wheel (51) (5) with axle (31), rear wheel frame and trailing wheel with support (4) do move forward and closing in the car body both sides.Wherein handlebar is used for the hand wheel car direction of travelling.

Referring to Fig. 2 structure of car body as can be known.Fig. 3 represents that support (4) is passed the drive rear wheel frame forward and trailing wheel closing car body both sides are that car body is finished contractive action.As seen from Figure 4, the adjustment of length over ends of body realizes by adjusting screw rod (21) and nut (22).

Referring to Fig. 4, Fig. 9 as can be known, the chair back of seat (6) is provided with handrail (63), and handrail is connected with angle Support (65) with the chair back, and handrail can rotate up, and closing is in chair back both sides.

Referring to Figure 10 as can be known, the chair back (6) and seat support (6A) are engaged togather through a bonding pad (61), are connected with rivet (62) between this bonding pad and seat support, and seat support is axially to rotate with chair back closing from rivet.

The bottom surface of seat support (6A) respectively is provided with an intubate (64) in the axle (31) that inserts same support (4) linking for four jiaos, is combined as a whole with fixing flexible skeleton with seat and car body.

Referring to Fig. 1, Fig. 5, Fig. 6 as can be known, joystick (55) upper end in order to the transmission trailing wheel is provided with a sleeve-like handle (54), it borrows an axle (59) with inflection point to be connected with joystick, handle inner spring (58) joins with axle (59), when collection or travelling wheel car, bending downwards again can make handle be attached on the joystick after handle drawn outward.

Drive wheel disc (57) rotation when manpower drives joystick (55), drive trailing wheel (51) rotation, the wheel car is advanced by chain (56).

From Fig. 7, Fig. 8 as can be known, the front end of rear wheel frame (5) is extended with a foot-driven lever (53) downwards, there is a stretcher (52) this foot-driven lever lower end, stretcher can be according to foot-driven lever rotation transformation position, and utilize the spring (531) that is provided with in the foot-driven lever to come in the hole (533) of clip on stretcher with clip pin (532), and fixed the stretcher after shifting one's position.

Reach embodiment shown in the drawings in sum and show that the purpose of this creation reaches, provide a kind of can the folding reduced volume, convenient collection or carrying, and can take turns the car structure by the disabled person of user's stature height adjustment length over ends of body.
