Abstract
The utility model relates to a folding wheelchair for going upstairs, which not only is suitable for going upstairs, but also is suitable for walking in the level road. The folding wheelchair for going upstairs comprises a main frame, an inclined frame, a chair seat and the like which are hinged, wherein the lower portion of the main frame is provided with a planetary gear group, and the lower portion of the inclined frame is provided with a universal wheel. When going upstairs, the universal wheel departs the ground surface, and the planetary gear group is only used, so the wheelchair can very stably going upstairs. When walking in the level road, the planetary gear group and the universal wheel get to the ground at the same time, which can evenly bear the weight and flexibly steering. The wheelchair has simple structure, small volume and light weight. The folding can be completed only by transferring the chair seat, so the carrying is very convenient.
Description
Technical field:
This utility model relates to a kind of collapsible stair-climbing wheel chair.
Background technology:
The kind of stair-climbing wheel chair is a lot, but there is following deficiency in majority:
General crawler belt or the walking elevating mechanism of adopting used motor-driven, again by reductor or pump, drives wheelchair.As seen, complex structure, volume is big, and heavy walks to the stair turning point, turns to difficulty, more is not easy to fold and carry.The building is climbed in only being good at of having, and is bad at away level road.
Summary of the invention:
The purpose of this utility model is exactly at above-mentioned deficiency, provides a kind of portable folding, promptly is suitable for climbing the wheelchair that the building is suitable for level road again.
This utility model is a kind of folding stair-climbing wheel chair, it mainly by body frame, tiltedly frame, seat, planetary gear set, etc. several parts form, it is characterized in that:
1, the body frame of this wheelchair, its main body is the rectangular frame that a straight-bar is formed, backrest is equipped with on its top, and recedes.Axletree is equipped with in its bottom.Its both sides have chute.
2, the oblique frame of this wheelchair, its main body is the U-shaped framework that a straight-bar is formed, and handrail is housed about it, in its bottom vertical rod universal wheel is housed.Axostylus axostyle is equipped with on its top, and tiltedly frame is bumped in the chute of body frame by axostylus axostyle, and is hinged with body frame.
3, the seat of this wheelchair, the chair axle is equipped with at the rear portion, and little axle is equipped with at the middle part, and seat is hinged by chair axle and body frame, and is hinged with oblique frame by little axle.
4, the planetary gear set of this wheelchair is made up of wheel plate and star-wheel, and planetary gear set is contained on the axletree by the centre bore of wheel plate, and star-wheel is contained between two wheel plates, and is the heart with the axletree, and annular is uniform, and the spacing of star-wheel is consistent with the step pitch of stair.
Compare with existing similar technology, the utlity model has following good effect:
1, when climbing the building, planetary gear set revolves round the sun around axletree, and star-wheel enters the stair recess successively, owing to got around projection, makes wheelchair climb following time upstairs, and is very steady.
2, when walking level road, two star-wheels at forward universal wheel of wheelchair and rear portion land simultaneously, and carrying is evenly advanced steadily, turns to flexibly.
3, simple in structure, volume is little, and is in light weight, as long as move seat, just collapsible, carry very convenient.
Description of drawings:
Fig. 1 looks sketch map for master of the present utility model.
Fig. 2 is a schematic side view of the present utility model.
Fig. 3 is the sketch map of this utility model after folding.
The specific embodiment:
Below in conjunction with accompanying drawing, this utility model is done more detailed description:
The master of shown in Figure 1 is this stair-climbing wheel chair looks sketch map.
From Fig. 1 as seen: this stair-climbing wheel chair mainly by: body frame 2, tiltedly frame 12, seat 14, planetary gear set 5, etc. part form.
From Fig. 1 as seen: body frame 2 is equipped with backrest 1 and axletree 6, and both sides have chute 7.
From Fig. 1 as seen: about oblique frame 12 handrail 11 is housed, in its bottom vertical rod 9 universal wheel 15 is housed.Axostylus axostyle 8 is equipped with on its top, and by axostylus axostyle 8, iron chains are gone in the chute 7 of body frame 2, and can slide and rotation in groove 7, thereby hinged with body frame 2.
From Fig. 1 as seen: chair axle 3 is equipped with at the rear portion of seat 14, and little axle 13 is equipped with at the middle part, and by chair axle 3, and is hinged with body frame 2, by little axle 13, hinged with oblique frame 12.
From Fig. 1 as seen: planetary gear set 5, to form by wheel plate 10 and star-wheel 4, planetary gear set 5 by the centre bore of wheel plate 10, is contained on the axletree 6 of body frame 2 bottoms.Star-wheel 4 is that thimble shape is uniform with the axletree, like this, star-wheel 4 can rotations also can be around axletree 6 revolution, the spacing of star-wheel 4 is consistent with the step pitch of stair.When climbing the building, grasp the cross bar on the body frame 2, the pulling wheelchair, this moment, wheelchair receded, universal wheel 15 built on stilts, center of gravity moves on the planetary gear set 5, under the stopping of stair, forces star-wheel group 5 around axletree 6 revolution, star-wheel 4 enters the stair recess successively, since avoided the step projection, when making wheelchair climb the building, very steady.When walking level road, promote wheelchair forward, at this moment, two star-wheels 4 at forward universal wheel 15 and rear portion land simultaneously, and carrying is evenly advanced steadily, turns to flexibly.
Shown in Figure 2 is the schematic side view of this stair-climbing wheel chair.
From Fig. 2 as seen: grasp the cross bar on the body frame 2, can implement push-and-pull to wheelchair.
From Fig. 2 as seen: both feet can be placed on the cross bar of oblique frame 12.
From Fig. 2 as seen: star-wheel 5 is contained between two wheel plates 10.
Sketch map after shown in Figure 3 is this stair-climbing wheel chair is folding.
From Fig. 3 as seen: when upwards lifting seat 14, seat 14 is the heart with chair axle 3, clockwise rotates, and upwards lifts by the oblique frame 12 of little axle 13 drives, forces axostylus axostyle 8 to move up along chute 7, and oblique frame 12 is drawn in, and it is folding to finish wheelchair.
