EASY COVER IMSTALLATION WHEELCHAIR

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cover-mounted wheelchair which can be used by a person with a disability or an elderly person.

Wheelchairs are being used as a means of transportation for people with mobility problems such as the elderly or the disabled, and a variety of auxiliary means for more convenient use of wheelchairs are being developed. Such a wheelchair is used both indoors and outdoors, and when used indoors after outdoor use, there is a problem of contamination of the room due to contaminants on wheels. Therefore, wheelchair wheels must be cleaned before taking them outdoors after use outdoors. However, there was a problem that it was very inconvenient to clean it every time it was brought into the room. Therefore, a cover for wheelchair wheels was designed so that the wheel does not need to be cleaned when bringing the wheelchair into the room.

FIG. 1 is a view showing a conventional wheelchair wheel cover. The cover body portion 100 having the abdomen portion 110 made of cloth can be put on the wheels of the wheelchair before the wheelchair is used outdoors and then brought into the room. Further, after the cover body portion 100 is mounted, it can be firmly fixed by the fixing jig 220 when necessary. Therefore, there is an advantage that the wheelchair can be used indoors without cleaning the wheel after outdoor use of the wheelchair.

However, in this case, it is very difficult for the disabled person who has a disability to perform the operation to cover the cover body 100 while lifting the wheelchair from the ground or moving from the ground, and it may be impossible when the degree of disability is severe. There is a problem.

The cover-mounted wheelchair according to an embodiment of the present invention includes a main body, a lifting portion, and a cover mounting portion 400.

The main body includes a chair 110, and a pair of supporting beams 140 extend from the front end of the chair 110 to the ground. Small wheels 141 are rotatably attached to the lower ends of the support beams 140 to support the support beams 140.

The seat frame 210 is coupled to the lower portion of the support beam 140 such that the seat frame 210 is supported at a lower portion of the seat 110 so as to support the seat 110 when the wheel 120 is lifted upward, Is disposed between the pair of wheels (120).

The pair of wheels 120 are connected by a rotating shaft 130 and the rotating shaft 130 is connected to a chair 110. The pair of wheels 120 are rotatably connected to a pair of main beams 310 extending downward from the chair 110 . At this time, a slit-shaped through hole is formed in the main beam 310 so as to penetrate the main beam 310 along the longitudinal direction of the main beam 310. Accordingly, the rotating shaft 130 is slidable with respect to the main beam 310 along the slit-shaped through-hole.

A horizontal support plate 211 is fixedly coupled between the support beam 140 and the seat frame 210. A slit-shaped through-hole is formed in the horizontal support plate 211 so as to be slender along the longitudinal direction of the horizontal support plate 211 do.

The horizontal support plate 211 and the chair 110 are connected by a cross beam 320. The upper end of the cross beam 320 is rotatably connected to the chair 110 and the lower end of the cross beam 320 is linked to a slit-shaped through hole formed in the horizontal support plate 211. Therefore, the lower end of the cross beam 320 is slidable along the through hole of the horizontal support plate 211.

The cross beam 320 is connected to one end of the sub cross beam 330 and the other end of the sub cross beam 330 is connected to the rotation axis 130 so as to be rotatable.

A slit-shaped through-hole is formed in the lower portion of the cross beam 320 along the cross beam 320 and one end of the drive beam 340 is linked to the slit-shaped through hole of the cross beam 320 . Accordingly, one end of the driving beam 340 is slidable along the through-hole of the cross beam 320.

A foot plate 341 is fixedly coupled to the other end of the driving beam 340 and one point between both ends of the driving beam 340 is rotatably coupled to the supporting beam 140.
