Abstract

Provided is a wheelchair assisting people disabled in lower limbs in moving. Members of the wheelchair such as a seat and a backrest are unfolded or folded through variable geometric structures connected with each other so as to achieve the goal of minimizing an occupied space when the wheelchair is carried. Besides, a manual driving device and an electric driving device can be added to frames of the structures so as to facilitate long-distance walking of the people disabled in the lower limbs. The people disabled in the lower limbs can go out or ride in various vehicles conveniently.

Description

Portable foldable wheelchair

Technical field

The present invention has related to the auxiliary wheelchair of taking action of a kind of lower limb disabled.This wheelchair can fold with it, and volume is small and exquisite, can make lower limb disabled trip, perhaps carries the various vehicles more convenient.

Background technology

Present generally popular fully collapsible invalid's chair in the life, although by folding can reduced volume, when the various vehicles of lift-launch, pack up and place the restriction that still is subject to vehicle space.Particularly rely on arm paddling wheel as type of drive, can not apply continuous continual power to wheel, therefore be not easy to long distance walking; Disabled's activity space is greatly limited.Because the wheel diameter of arm paddling is larger, it is also the biggest obstacle of dwindling the wheelchair volume.

Electric wheelchair although alleviated the disabled's physical exertion intensity, can satisfy the needs of long distance walking; But when carrying other vehicles, volume and weight is met difficulty equally.Wheelchair moving up and down during to equipped vehicle neither can be completed with manpower.Present way is to configure mechanical hand on vehicle, slings as crane and puts down.The convenient feature flexibly of same shortage.

The lower limb disabled that particularly possess the ability of driving a car have had the condition of oneself long journey, but when using traditional push chairs, or are getting on or off the bus, and more highlight difficulty during exchange device (wheelchair).If at this moment there is one one, small volume and less weight, energy is the long wheelchair apart from walking of muscle power gently, and facilitates people with disability oneself to move, the wheelchair of (put down from car, bring up), the change that can bring quality to lower limb disabled's life undoubtedly.

Summary of the invention

The present invention is by interconnected variable-geometry, and by clockwise expansion, counterclockwise closed mode is with the structural member developments or folding such as seat of wheelchair.Reach wheelchair when carrying with it, minimized purpose takes up room.And can install manual rocking bar additional on the framework of this structure, Vidacare corp facilitates the long distance walking of lower limb disabled.While also makes the space below the seat, more easily puts darker Excreta container.

Embodiment:

Purpose of the present invention is to be achieved by the following technical programs.

1, the main structure body of this wheelchair as shown in Figure 3, when wheelchair uses, with seat (4) take fulcrum (131) as axle, clockwise rotate, when making locating hole (132) on support bar (3) overlap to the same axis with locating hole (126) on main support (5), locating hole (132) and locating hole (126) is locked with positioner, wheelchair namely enters the steady statue when using, this moment, the transport condition of wheel-chair was completed, can use motorized motions or manual rocking bar, reach the purpose of walking.

2, when completing walking, when needing to place, the positioner of removing between locating hole (132) and locating hole (126) is locked, and sliding seats (4) rotates counterclockwise take fulcrum (131) as axle, draws in to backrest (1) direction; Fore-stock (6) and main support (5) and support bar (3) are take the fulcrum (127) of backrest (1) other end as axle, draw in to backrest (1) direction with seat (4), this moment main support (5) also under the pulling of seat (4) take fulcrum (124) as axle, and under the support of after-poppet (10) two ends fulcrums (129) and fulcrum (128), close up to backrest (1) direction simultaneously.This moment, handrail upper support (8) and handrail lower support (9) were when also rotate (4) at the seat, transfer rounding state to by deployed condition, pull simultaneously handrail (2) parallel with backrest (1), at this moment body construction has namely reached the order ground of foldable integral; As shown in Figure 1, realize the minimized purpose of wheelchair.

Claims
