Wheelchair Wheelchair for Poor

The wheelchair for indoor use is intended for use as a hand-held vehicle for people with disabilities, as well as for people who, for some reason, have restrictions on the use of the musculoskeletal system indoors.

There are known designs of wheelchairs intended for outdoor use indoors, containing a base on which the seat and backrest, armrests, footrest, support wheels are fixed: two leading rear wheels equipped with hoops for their manual rotation and two supporting self-orientating wheels in front. The seat is located between the drive wheels, therefore the wheelchair has a width of more than 600 mm (see the catalog of the company Shyra, Germany, 1982). The wheelchair of this type also requires significant turning space, since the turning center when turning in place is on the axis of the drive wheels, which are located behind. It is also inconvenient from this wheelchair to transplant the disabled person to another place: location, you can only transfer from it forward. Especially these shortcomings of these wheelchairs are manifested in small rooms, with narrow openings for toilet, bathroom, elevator, in rooms with narrow passages, lined with furniture.

Known for the design of a wheelchair, in which this is decided. problem (AS I796I73 MKI A 61 5/06) by disconnecting the mounted on separate parts from the left I / right from the seat-chair pairs, ;; the support wheels, so that the person remains disconnected after disconnecting them | on a chair with additional small wheels on the legs of the chair and moves in a narrow place, pushing hands off walls and furniture. Although the problem is solved, it is inconvenient to move on such a stroller after disconnecting the drive wheels. In the design of a wheelchair for rooms RS / 2038064 RF MKI A 6 G- 5 / 0.2, 5/06, the closest analogue to the claimed one, the widths due to the placement of the seat above the wheels do not exceed the width of the seat, the drive wheels located in front, closer to the middle. This arrangement provides the best opportunity

displacement. in small spaces, this wheelchair also makes it possible to transplant a person not only forward, but also sideways, left and right. A positive factor is also a brake actuator acting on the drive wheels from one handle.

The disadvantages of this coystruktsiya following:

-complexity of the structural base containing the longitudinal beam and telescopic stand, on which the seat is fixed,

 lack of handles for moving the disabled person when it is impossible to move independently,

- the complexity of the device of the brake mechanism, as well as the inconvenience of using the handle located under the front light, especially for the disabled, wearing a dress or bathrobe,

- uncomfortable ps) to the wheelchair in front, where the base beam and the footboard with the front support wheel come out.

The purpose of the claimed utility model of the wheelchair for the premises is to significantly simplify the design and ensure the convenience of using the wheelchair in small-sized conditions. rooms with narrow aisles, and doorways by making the base of the stroller made of e with handles for transporting wheelchairs, with the footrests extending to the sides to ensure a comfortable approach when riding, and making the brake handle in the form of one, for airway: at the same time on two rims of the drive wheels of the handle, but e two levers brought out on the sides of the wheelchair, - At the same time in the device of the wheelchair, the possibility of using the product in a small-sized room, namely: : The drive wheels under the seat, the presence otkidy shschihsya armrests.

The prizash described below provide ease of use when landing a disabled person, when transplanting to another place, when driving in cramped conditions :, C | ® using brake devices, footrests and UNDERGROUND, at the same time, the design of the wheelchair is simpler and more technol®E1ganee,

On representations of graftsesky materials shown in Fig.1 side view, in Fig. 2 "ЩЦ from above on a wheelchair.

casting wheels 7, steps 8, auxiliary rollers 9, handles 10, brakes 11, levers 12 of the brake mechanisms mounted on a common shaft G with crank brakes of the NSC mechanisms. Driving kilos removed under the ode-nv creole wheelchair, so the size

When a person is landing, the steps of the footboard 8 can be folded to the sides and both pedals can be folded: ® the bow can also be folded so that you can move on either side. The levers 12 are located on the sides of the stroller, which can be braked using the brake mechanisms II. When the levers 12 are acted upon simultaneously with two hands or one Q on either side. A wheelchair with a person who can be transported using the handles 10, when independently moving, a person with a disability uses handrails 6, while due to the front arrangement of the driving wheels, closer to c, the middle of the size of the wheelchair in length, it is possible to deploy in a limited space.

The proposed utility model of the wheelchair is simple in design, technologically advanced and does not present difficulties with industrial implementation. The enterprise has developed design documentation, made an experimental batch of products, tested it, and is preparing mass production.
