Description
The present invention relates to a kind of wheelchair, particularly a kind of double-purpose simple wheelchair for sleeping or sitting on it.
Along with aging society is arrived, the wheelchair demand increases, and simultaneously its technical functionality is also had new requirement.Old man's wheelchair time is long slightly, and is tired drowsy, if wheelchair also becomes bed, just more convenient; In hospital or the nursing house,, just can save many time of nursing staff if wheelchair can arbitrarily be with the people to be transformed to doss.
Existing sitting-lying double-purpose type wheelchair, complex structure, part are many, troublesome poeration, effort, the flat comfort level that crouches is relatively poor, fails to adapt to the requirement of social reality.
Purpose of the present invention is according to real needs, and it is simple especially to propose a kind of structure, rapid operation, the action single, the sitting-lying double-purpose wheelchair of better performances.This wheelchair only need shake a crank, just can arbitrarily be with people's conversion to sit up straight, lean to or the flat state that crouches, and can make doss and use, and makes us comforting conveniently, and improves nursery work efficient, reduces labor intensity.
Purpose of the present invention can reach by adopting following measure:
Double-purpose simple wheelchair for sleeping or sitting on it comprises seat portion and is installed on the four wheels of its below, also have with seat portion after go up the hinged back-rest in angle, handrail, its construction features is, goes up the hinged legs and feet portion in angle before also comprising its middle part and seat portion; The handrail two ends are hinged with back-rest and legs and feet portion upper end respectively; The back bracket hinged with the portion that leans against; Also comprise the support pull bar, the one end is hinged with the sheer pole that is connected in seat portion, and the other end is hinged with the movable cross bar that is connected in back bracket; Also comprise flexible screw rod, the one end is hinged with the cross tube that is connected in seat portion, and the other end passes the through hole at movable cross bar middle part, and is connected with a crank; The lining that also comprises steady rest and support human body.
Construction features also has:
The hinged place at legs and feet portion middle part is to 15 °-35 ° of front curve.
The side projection of this wheelchair shows, constitutes triangle by hypomere after the support pull bar in the member, flexible screw rod and the seat portion.
Constitute first four-bar mechanism by hypomere, support pull bar, back bracket and back-rest after the seat portion.Constitute second four-bar mechanism by seat portion, back-rest, handrail and legs and feet portion epimere.And in fact integral body constitute a six-bar mechanism.
Compared with prior art, the present invention has following advantage:
When 1, being transformed to flat crouching, be equivalent to the plain sail bed, comfortable convenience.
2, operation only needs a crank, move single, laborsaving, motion steadily, back-rest and the interlock of legs and feet portion, also energy self-locking of stepless adjustment.
3, simple in structure, part is few, and is cheap, is suitable for and implements and popularization.
Fig. 1 is double-purpose simple wheelchair for sleeping or sitting on it embodiment, and its composition comprises wheel 1, seat portion 2, back-rest 3, legs and feet portion 4, handrail 5, back bracket 6, cross tube 7, sheer pole 8, movable cross bar 9, support pull bar 10, flexible screw rod 11, crank 12, steady rest 13 and lining 14.
Shown in Figure 2, from top to bottom be respectively the state of sitting up straight of this double-purpose simple wheelchair for sleeping or sitting on it embodiment, a certain angle and lean to the flat state that crouches that doss is made in state and change.
Referring to Fig. 1 and Fig. 2, when shaking crank 12 counterclockwise, in this wheelchair side projection, constitute triangle flexible screw rod 11 elongations on one side, and make support pull bar 10 bottoms that constitute the triangle another side; In first four-bar mechanism, support pull bar 10 bottoms make the back bracket 6 of the connecting rod effect of having held concurrently drive back-rest 3 again to fall; In second four-bar mechanism, handrail 5 drive legs and feet portions 4 risings of falling and make the connecting rod effect of having held concurrently of back-rest 3.Back-rest 3 links by handrail 5 with legs and feet portion 4.Fall and in the legs and feet portion 4 ascending motion processes state that leans to that adapts with human body natural's bending that promptly presents various angles at back-rest 3.When continuing to move to back-rest 3, seat portion 2 and legs and feet portion 4 when being in same plane, this wheelchair promptly becomes the crouch bed of state of a Zhang Ping.At this moment, back bracket 6 lands, and two back wheels 1 play braking action simultaneously, and guardrail are made in handrail 5 changes slightly from sky.Otherwise,, can be returned to the state of sitting up straight originally again as shaking crank 12 more clockwise.
Because motion is to be initial member with the screw rod that rotates, it is steady, laborsaving to move, the stepless adjustment of lifting angle, and screw rod itself has self-locking action, need not ad hoc locking member, can make the locking at any time under any state of this double-purpose simple wheelchair for sleeping or sitting on it, safe and reliable.
For making things convenient for user on wheelchair, oneself to adjust conversion, can set up a flexible axle, in order to the flexible screw rod 11 of transmission, and the crank of flexible axle can be placed on the position that user is convenient to operate.
