Abstract

FIELD: transportation.

SUBSTANCE: self-propelled underwater wheelchair including a wheelchair frame, a seat, a backrest, footsteps, front wheels, rear wheels, hoops of the rear wheels, characterized in that it contains on both sides mirror-symmetrically located supporting frames fixed on the hoops of the rear wheels by means of quick-detachable retaining hooks, as well as vertical guides, wherein on the supporting frames wings are installed, made of composite material and equipped with cutouts for installing propellers fixed on the vertical guides of the supporting frame.

EFFECT: creating a wheelchair, the design of which would allow a disabled person to move under water, while making all the necessary movements with the complete controllability of the wheelchair.

Description

The invention relates to personal vehicles specifically designed for people with disabilities in motion.

In connection with the increasing public attention to the fate of people with disabilities, there is a need to expand their areas of activity, including in areas such as sports and entertainment.

One of these areas is scuba diving. However, the sphere of scuba diving for the disabled with leg injuries remains undeveloped.

There are a large number of wheelchairs of a traditional design that allow a disabled person to travel by land with both manual and mechanical drives.

(Source: http://gradusnik.pro/tipy-invalidnyh-kolyasok.html).

So, the wheelchair adopted by the authors for the prototype is known, including a stroller frame, seat, backrest, armrests, two rear wheels with external hoops, two front wheels, footboards (Source: http://www.medinvalid.ru/index.php?categoryID = 557).

The disadvantage of this device is its limited capabilities, not allowing the stroller to move under water.

The objective of the invention is the creation of a wheelchair, the design of which would allow the disabled person to move under water, making all the necessary movements (turns, turns, turns 360 degrees, swimming down and up) with full control of the stroller.

This problem is solved in that the self-propelled underwater wheelchair, including the stroller frame, seat, backrest, footrests, front wheels, rear wheels, rear wheel hoops, contains on both sides mirror-symmetrically supported load-bearing frames fixed to the rear wheel hoops with quick-release hooks -fixers, as well as vertical guides, while wings are made on composite frames made of composite material and equipped with cutouts for installing propulsors mounted on vertical guides constituents of the base frame.

The invention is illustrated by drawings, which show:

FIG. 1 - General view of a self-propelled underwater wheelchair.

FIG. 2 - The same as in FIG. 1, with the mover removed.

FIG. 3 - Mover with mounting straps.

Figure 4 - Bearing frames of the movers with landing slots and vertical guides.

FIG. 5 - Locking hooks.

FIG. 6 - Wings assembly with hooks and latches.

FIG. 7 - The angle of inclination of the carrier frame with propulsors relative to the stroller.

Self-propelled underwater wheelchair is made on the basis of a standard (walking, room) wheelchair with manual control.

A self-propelled underwater wheelchair (Figs. 1 and 2) includes a frame 1, a seat 2, a backrest 3, a step 4, two front wheels 5, two rear wheels 6, hoops of the rear wheels 7. To provide the possibility of movement under water, the carriage from two the sides is equipped with supporting frames 8 with hooks-clamps 9 and vertical guides 10, propellers 11.

On the supporting frames 8, wings 12 are installed, equipped with cutouts A for mounting the propulsors 11 (Fig. 6). Movers 11 are fixed to the supporting frames 8 using rubber slings 13 to the vertical guides 10.

Bearing frames 8 and vertical guides 10 are made of alloy, durable stainless metal by argon-arc welding. (Fig. 4 and 5). Two wings 12 are made of composite material on which movers 11 are mounted.

As propellers, submarine towing vehicles such as the Sea Doo Seascooter GTI can be used.

The whole structure can be made both non-separable and collapsible, which allows to reduce its dimensions during transportation.

Assembling a self-propelled underwater wheelchair is as follows.

The wings 12 are mounted on top of the supporting frames 8 and secured with screws along the perimeter. On the hoops 7 of the rear wheels 6 of the stroller, the hooks-clamps 9 are hooked in the shape of an asterisk, and simultaneously between them and in the center of their connection, the supporting frame 8 is installed in the landing slots 14, tightened with a fixing bolt 15.

From above, movers 11 are mounted on wings 12 into cutout A, which are fixed with hooks of rubber slings 13 (Fig. 3) to the vertical guides 10 of the supporting frames 8 (Fig. 4).

Self-propelled underwater wheelchair is used as follows.

Before diving, for training in scuba diving (diving), a special wetsuit and mask are put on the disabled pilot. The pilot is secured with a special waist belt to the wheelchair. His legs are fixed with a special belt to the steps 4. When immersed, the disabled person applies a mouthpiece inserted into the mouth, through which oxygen from the scuba gear suspended by the straps from the backrest 3 is supplied.

A disabled pilot holds onto the handles of the propulsors, on which the triggering mechanism of the propulsors is located. Already in the water, the stroller pilot at the right time starts the propulsion mechanism of the propulsion, thereby providing movement in the aquatic environment. To sail straight, it simultaneously includes two movers 11.

If you need to turn right, it turns on the left mover, if left, then - right. In the case of moving up or down, the disabled pilot includes alternately or simultaneously the triggering mechanism of the movers, while making lever movements, directing the movers up or down (Fig. 7) by scrolling the rear wheels 6, on which the movers 11 are fixed (Fig. 1, 2).

The rear wheels of the wheelchair act as controls.

An underwater wheelchair will allow people with disabilities to travel under water, regardless of their limited motor capabilities. It can be controlled even by a person who does not have legs!

A self-propelled underwater wheelchair can be used for the rehabilitation of disabled people with impaired musculoskeletal system, as well as for water activities on the surface of the water, in shallow water.

Technical characteristics depending on the model of towing vehicles (propulsors):

1. Depth of immersion - up to 50 m

2. Weight - 30-60 kg

3. Speed - 4-7 km / h

4. Operating time - 60-90 minutes

5. Modes - up to 3 speeds

6. Dimensions - 900 × 900 × 1000 (1500) cm

Claims (1)

A self-propelled underwater wheelchair including a stroller frame, seat, backrest, footrests, front wheels, rear wheels, rear wheel hoops, characterized in that it contains mirror-symmetrically supported load-bearing frames fixed on both sides of the rear wheel hoops with quick-release hooks - retainers, as well as vertical guides, while wings are made on composite frames made of composite material and equipped with cutouts for installing propulsors mounted on vertical guides conductive frame.
