Abstract

An auxiliary ring structure for a hand propelled wheelchair (Figure 4) includes a ring 1 made of plastic material. A number of grip sections 11 protrude inwardly from the ring, are spaced from each other, and have outer diameters larger than that of said ring. Each grip section may be wrapped and secured with a pad 2, held in place by means of fixtures 22 and corresponding holes 13, for the user to grasp in a comfortable way. The ring is easy to hold, light in weight, and cost-effective.

Description

AUXILLARY RING STRUCTURE FOR A WHEELCHAIR
The present invention relates to an auxiliary ring structure for a wheelchair, and more particularly to a ring made of plasc material and provided with a number of grip sections protruded inwardly from the ring and equally spaced each other for the user to grasp securely and comfortably.
A conventional wheelchair in the market comprises a hand rail attached to a wheel for the user to hold the hand rail and control the wheelchair to move in an easy way. However, the hand rail is made of metal material which is slippery and may sometimes cause the user to loose control of the wheelchair.
In order to make improvement in the above-mentioned shortcoming, US Patent No.7,040,642 disdosed a cover for a wheel chair grip ring, which is provided with a sleeve on the ring. The sleeve comprises an inner pad and an outer layer attached to the inner pad for convenient grip ad anti-skip.
This design has made some improvement on the above shortcoming.
However, when the wheelchair is rolling on a downhill, the wheel will roll fast, which makes the ring hard to control and also may bum the user's hand.
The other shortcoming of the prior art is that the wrapping of the ring requires more material and man power, thus it is not cost-effective.
According to the present invention, there is provided an auxiliary ring structure for a wheelchair comprising a ring made of plastic material, a number of grip sections being inwardly protruded from said ring and spaced each other, each said grip section having an outer diameter larger than that of said ring and an enlarged middle portion.
Preferably, each of said grip sections is provided with a pad.
Preferably, said pad is made of soft material.
Preferably, each of said grip sections is formed with a dent facing ) outward, and said pad is formed with a wrapping section to cover said dent.
Preferably, said dent is provided with holes thereon, and said wrapping section is provided with fixtures to engage with said holes of said dent.
Preferably, said holes of said dent and said fixtures of said pad are corresponding insertion holes and bolts, threaded holes and screws, or through holes and rivets.
Preferably, said ring comprises a number of securing sections thereon.
Preferably, said ring is a hollow tube.
It is the primary object of the present invention to provide an awaliary ring Jo structure for a wheelchair, which comprises a number of grip sections equally spaced on the ring for the user to hold and control moving and turning of the wheelchair.
lt is another obiect of the prcent invert!on to provide n xarj ring structure for a wheelchair, which provides a ring made of plastic material.
It is a further object of the present invention to provide an auxiliary ring structure for a wheelchair, which is provided with pads on the grip sections to provide the user with comfortable grasping and preventing the user from injury.
It is still a fUrther object of the present invention to provide an auxiliary ring structure for a wheelchair, which is cost-effective because the pads are provided independently on the ring.
There now follows a description of preferred embodiments of the invention, by way of non-limiting example, with reference being made to the accompanying drawings in which: Figure 1 is an exploded view of a first embodiment of the present invention; Figure 2 is a partially perspective view of the first embodiment of the present invention;
J
Figure 3 is a cross-sectional view of the first embodiment of the present invention; Figure 4 is a perspective view of the first embodiment of the present invention mounted to a wheelchair; and Figure 5 is a perspective view of a second embodiment of the present invention.
As shown in Figure 1, a preferred embodiment of the present invention comprises a ring I and a number of pads 2.
The ring 1 is a hollow tube made of plastic material. A number of grip sections 11 are inwardly protruded from the ring I and equally spaced each other. Each grip section 11 has an outer diameter larger than that of the ring 1 and an enlarged middle portion. Each grip section 1 is formed with a dent 12 facing outward. A number of holes 13 are formed on the dent 12 which may be insertion holes, threaded holes or through holes. In this embodiment, the holes 13 are insertion holes. A number of securing sections 14 are provided on the ring 1.
The pads 2 are made of soft material and shaped to cover the dents 12 of the ring 1. Each pad 2 comprises a wrapping section 21 and a number of fIxtures 22 therein. The fixtures 22 may be bolts, screws or rivets. In this embodiment, the fixtures 22 are bolts.
To assemble the present invention, as shown in Figures 2 and 3, each pad 2 is secured to the ring I with the wrapping section 21 covering the dent 12 of the grip section 11 of the ring 1 and the fIxtures 22 inserted into the holes 13.
To use the present invention, as shown in Figure 4, the securing sections 14 of the ring 1 are secured to a wheel Al of a wheelchair A so that the user may grasp the grip sections 11 to control the wheel Al through the ring 1 to
J
move or to stop. The grip sections 11 of the ring 1 provide an anti-skip effect so that even the wheelchair A is rolling along a down slope in a faster speed, the user can still control the wheel Al easily.
As shown in Figure 5, another embodiment of the present invention comprises a ring 1A which is a hollow tube made of plastic material. A number of grip sections ilA equally spaced each other are inwardly protruded from the ring IA Each grip section ilA has an outer diameter larger than that of the ring 1A, which provides the user an easy way to grasp and to operate the ring IA
