手动轮椅 - NSL980LA41

A self-propelled manual Wheel Chair incorporates a frame, seat, one or two footplates (footrests) and four wheels: usually two caster wheels at the front and two large wheels at the back. There will generally also be a separate seat cushion. The larger rear wheels usually have push-rims of slightly smaller diameter projecting just beyond the tyre; these allow the user to manouevre the chair by pushing on them without requiring them to grasp the tyres. Manual wheelchairs generally have brakes that bear on the tyres of the rear wheels, however these are solely a parking brake and in-motion braking is provided by the user’s palms bearing directly on the push-rims.

As this causes friction and heat build-up, particularly on long downslopes, many Wheel Chair users will choose to wear padded wheelchair gloves. Manual Wheel Chair often have two push handles at the upper rear of the frame to allow for manual propulsion by a second person, however many active wheelchair users will remove these to prevent unwanted pushing from people who believe they are being helpful.

每天的手动轮椅有两个主要品种，折叠或刚性。折叠椅通常是低端设计，其主要优势是能够折叠，通常是通过将两侧融合在一起。但是，对于兼职用户来说，这在很大程度上是一个优势，他们可能需要比使用它更频繁地存放轮椅。

Rigid wheel chairs, which are increasingly preferred by full-time and active users, have permanently welded joints and many fewer moving parts. This reduces the energy required to push the chair by eliminating many points where the chair would flex and absorb energy as it moves. Welded rather than folding joints also reduce the overall weight of the chair. Rigid chairs typically feature instant-release rear wheels and backrests that fold down flat, allowing the user to dismantle the chair quickly for storage in a car. A few wheelchairs attempt to combine the features of both designs by providing a fold-to-rigid mechanism in which the joints are mechanically locked when the Wheel Chair is in use.
