Invalid chair wheel with diametrically rolling carriage segments having thrust support in form of corrugated rimmed disk

FIELD: medicine.

SUBSTANCE: invalid chair wheel is provided with diametrically rolling carriage segments having a thrust support in the form of a corrugated rimmed disk. Wheel carriage consists of segments rolling by guided pins fastened with its one end on a disk of the smaller diameter arranged on an axis of the presented wheel on the side and fulfilling a function of a concentrator of all these pins. The carriage represents separate segments of one-piece rubber tires reinforced with reinforcing bars attached with one end to a wheel rim, while the other end of each segment is attached to a free end of each pin fulfilling a function of a segment rolling drive. The above segments are rolled by means of a lever handle scrolling the disk concentrating the pins whereto it is attached.

The level of technology

Wheel to wheel chairs with diametrically drop-down segments chassis having a power base in the form of a corrugated disc rim, is structurally modified wheel to wheel chairs and flat-disc wheel (with the well-known constructive form [1]) and differs from it in the following design features: corrugated disk with the rim [2] - (horowimi dents converging towards the center from the edges of the disc divides the disk, in turn, into segments (different from the flat-disc wheel [12] that has greater horizontal tensile swinging)) - which gives him the strength the Foundation of its design, and the spokes [3] (fixed by its end on the disk of small diameter, located on the axis of the proposed wheel (side) and serves as the hub of all such spokes, as well as fulfilling the role of amp wiring segments chassis, representing individual segments of rubber solid tyres [4] reinforced pieces of rebar rods [5], and an attached end (which is the axis) to the wheel rim [6], and the other end of each such segment attached on the axis to the free end of each of the spokes (which serves as the drive mechanism of rscr is of segments), and from this side of themselves pieces of rebar rods are steel welding [10] - height flush with the outer diameter of the rubber part of the segment, the disclosure of these segments is, in turn, by means of the handle - lever [7]scrolling concentrating the spokes of the disk, which, in turn, permanently attached, and hold the segments of the undercarriage wheels in the open and closed condition specified spokes carried out or the outside of the wheel rim or the wheel rim through the holes in it, and by fixing specified handle by means of steel pins - built on the basis of the corrugated disk carrier of the wheel, and this invention is directed to facilitating the transportation of a disabled person sitting in this chair) on the stairs of the buildings (in the absence of them in the Elevator), and to achieve the claimed ability to be due to the opening segments of the undercarriage wheels in order to neutralize the differences of height between steps, turning movement on the stairs in an almost smooth ascent/descent of the chair with a disability. Moreover, the very basis of this wheel: corrugated disc rim - can be used to build Bicycle wheels - for picking their rental [11] for the army.

Disclosure of inventions

1. The proposed invention: a wheel for a disabled person who's chairs with diametrically drop-down segments of the chassis, with the basis of: corrugated disk with the rim [2] (with horowimi dents, converging towards the center from the edges of the disk, which divides the disk, in turn, into segments), which gives him strength to the Foundation of its design.

2. Equipped with corrugated disk: a disk of small diameter, provided with spokes (located on the axis of the proposed wheel (side)) and serves as the hub of all such spokes, and also acts as a amplifier wiring segments chassis, while the disk rotates freely on the axle of the wheel.

3. Suspension consists of segments of rubber solid tyres, reinforced with pieces of rebar rods.

4. Pieces of rebar rods, (curved under the radius of the wheel) is attached to the end (which is the axis) to the wheel rim and the other end of each such segment is attached on the axis to a free end of each spoke (acts as a drive mechanism for opening segments).

Waskita these segments is, in turn, by means of the handle-levers attached to concentrating spokes disk of small diameter.

6. Fixation of the handle and in the separated position of the wheel, and normal is due to the steel pins mounted in the bearing surface of the wheel disc, experimentally selected distance from each friend is, but to do so it is necessary to find the height of the opening segments of the undercarriage wheels, height of steps of different buildings in the same pen, which must be in the form of a thick steel strip, it is necessary to make a hole for the pins, which should be slightly curved in the direction opposite to the force of the folding segments undercarriage wheels.

7. Hold the segments of the undercarriage wheels in the open and closed condition specified spokes carried out or the outside of the wheel rim or the wheel rim through the holes in it.

8. From the drop - down segments to avoid punching shear rubber on their ends (in the open state which is the fulcrum on the floor) - on the back of pieces of rebar rods, the role of load-bearing foundations of rubber segments undercarriage wheels made surfacing steel with a height flush with the outer diameter of the undercarriage wheels.

9. This invention is directed: to facilitate the movement of a disabled person sitting in this chair) on the stairs of the buildings (in the absence of them in the Elevator), and to achieve the claimed ability to be due to the opening segments of the undercarriage wheels in order to neutralize the differences of height between steps, turning movement on the stairs in an almost smooth ascent/descent of the chair with a disability is m, situated therein, and the assistant, who was katyal would/have lowered the indicated chair, you will need as you move regular wheelchair in similar conditions.

10. Also the power from this invention: corrugated disc rim, can be used for the manufacture of Bicycle wheels - for picking these wheels rental for the army.

Brief description of drawings

1. In FIG. 1 shows the invented wheel Assembly (planar projection), the numbers indicate the following structural elements: 1 - pen turning concentrating spokes disc 2 - corrugated host drive, 3 - needle, 4 - drop-down segment of the undercarriage wheels, 5 - rim wheels, 6 - concentrating the spokes of the turning disc, 7 - steel pin fixing handles, 8 - standard Hoop rotation of the wheels by the hands of the disabled 9 axis of the wheel.

2. In FIG. 2 depicts invented the wheel (view the profile in cross-section)10 - cut reinforcement rod.

3. 2 of FIG. 3 shows the design of fastening the spokes on the side of the wheel rim (in the manufacture of such a variant of the attachment of the spokes to the drop down segments wheels).

The implementation of the invention:

1. This invention is planned to produce in metallurgical workshops, and running segments (in the role of a tire wheel) should be made on plants re the Ino-technical products.

2. It features making themselves the drop-down segments of the wheel should be attributed to the fact that the part which will be the mainstay in the open position (flat floor), must have steel cladding, navarova method of electric welding on the tip of a piece of reinforcing rod (which is a monolithic valve rubber segment) so that the cladding is flush with the outer diameter of the rubber segment to avoid punching shear rubber and damage drop-down segments, created at the end of the high pressure caused by the weight of the disabled person, coupled with the weight of the chair.

3. To produce corrugated disk coupled with the wheel rim preferably made of carbon fiber [8], however the high cost of manufacturing can be duralumin [9].

4. The drive is small in size, role concentrating spokes disk: can be produced from carbon or aluminium.
