Description

AN APPARATUS AND METHOD FOR IMPROVED MOBILITY
FIELD
The present invention relates to an apparatus and method for improved mobility, and in particular to a wheelchair for use in both built up locations and heavy terrain.
BACKGROUND
Wheelchairs have been used for over one hundred years by people with limited or no walking ability, to move from one place to another. This form of transport is convenient, as it is low cost, can be used by the individual with or without assistance, and is compact.
There have been many improvements in design over the years such as the addition of motors and controls to improve the independence of users. Additionally sports designs have allowed for greater stability when playing sports, and waterproof wheelchairs have allowed users to go into water and over sand.
It is more common to see wheelchairs in the workplace, university, schools and shops, with many such locations improving wheelchair access to allow more independence and freedom for wheelchair bound people. The basic design of the wheelchair however, is not conducive to easy access. Stairs, uneven ground, grass, rocks, and gravel create barriers to movement, limiting the wheel chair to be used in built up locations and on wheelchair paths. Often this means pathways with stairs must be avoided, increasing the time to move around a location.
The simple freedoms of traversing stairs, moving across a lawn, crossing a patch of gravel or dirt are unassailable barriers for some current wheelchair designs. Dirt, shale, gravel, rocky terrain, and sand are difficult terrains for conventional wheelchairs to navigate. This means outdoor activities such as a picnic in the park, going to visit a friend with stairs, or spending time countryside are out of reach of many wheelchair bound people. Spontaneity is lost, as outings must be made to known venues having wheelchair access, to avoid unknown barriers.
Additionally, weather conditions such as mud, snow, hail, rain are difficult to travail with conventional wheelchairs making out door locations hard to access especially in bad weather.
Thus it is an object of the invention to provide an apparatus for improved mobility, and in particular to a wheelchair for use in both built up locations and heavy terrain, or to overcome any of the abovementioned problems or at least provide the consumer with a useful commercial alternative.

According to another broad form of the invention there is provided a method of improving mobility including the steps of: providing a wheelchair having a frame, a seat with a back portion and a base portion mounted on said frame, said frame supported on two rear wheels and an interchangeable front wheel section; and removing the seat from the wheelchair to act as a car seat.
BRIEF DESCRIPTION OF DRAWINGS
The invention will now be described in reference to the following drawings in which: FIG 1 shows a side view of an embodiment of the invention with a heavy terrain front wheel section;
FIG 2 shows a side view of an embodiment of the invention with two small front wheels section;
FIG 3 shows a front view of an embodiment of the invention with a front wheel section having two small front wheels;
FIG 4 shows a back view of an embodiment of the invention with a front wheel section having a heavy front wheel; and
FIG 5 shows a side view of an embodiment of the invention with a front wheel section having a heavy front wheel on a sports wheelchair.
DESCRIPTION
As seen in FIG 1, a preferred embodiment of the invention comprises a wheelchair having a frame (10) suspended on wheels (20) by at least one wheel axel (21) a seat (30) having a back portion (31) and a base portion (32), mounted on said frame (10) to support a user therein.
As best shown in FIG 3 and FIG 4, a first (23) and second (24) rear wheel are rotatably mounted to a rear axle (21) attached to said frame (10) to allow the wheelchair to roll.
FIG 1 and FIG 2 show the front wheel section attachable to said frame. Additionally, the seat (30) is removable and attachable to the frame (10). The seat is formed from fiberglass and can be installed in the back seat of a car to form a car seat. Different seat sizes can be fitted to the wheelchair so that it can accommodate the growth of a child. The seat (30) is formed from a fiberglass base covered in foam and fabric. The seat (30) can be formed to contour to fit the specific user (child). The contour and dimensions of the seat can be changed as the user grows.
As shown in FIG 2 and FIG 3 a first front wheel section (40) has two small wheels (41, 42) attachable to the front and sides of the wheelchair, hi contrast; FIG 1 and FIG 4 show a second front wheel section (50) having a heavy terrain wheel (51) attachable in the centre of the front of the wheelchair.
A user can alternate between the first front wheel section (40) and the second front wheel section (50) to suit the terrain. The front wheels sections (40, 50) can be interchanged by either detaching the section not desired and attaching the desired section or switching between a stowed section in a non-use condition while the other section is in use.
The heavy terrain section (50) includes a heavy terrain tyre attached to a v- frame extending from under the front seat base. The heavy terrain tyre (51) includes deep tread for better fraction in loose surfaces and better handling in wet conditions. The heavy terrain tyre (51) is a fat tyre so that the air acts as a cushion to improve suspension. This allows air pressure to be changed so it can be reduced for travelling over sand or increased for travelling over hard surfaces.
Alternatively a plastic tyre, or solid tyre could be used to reduce the likelihood of punctures and flat tyres in outdoor terrain. As shown in FIG 4, the wheelchair includes a foot rest. This foot rest holds the adductors apart to hold the legs in a posturally desirable position. The foot rest is formed from fiberglass or vacuum formed thermosetting plastic such as low density polyethylene or high density polyethylene.
The embodiment shown is a collapsible, hand driven wheelchair with detachable front wheel sections that can be stowed in a car boot, when transporting the wheelchair, and the seat removed from the wheelchair frame and used as a car seat. This could be adapted to motorised wheelchairs as would be understood by a person skilled in the art.
FIGS 1 to 5 show a handle bar (60) so the wheelchair can be pushed from behind. Thus the wheelchair can be propelled more easily across rough terrain with the heavy terrain arrangement in place.
It will be evident to a person skilled in the art that numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore understood the invention may be practiced otherwise than as specifically described herein.
