Abstract

A Comfortable Wheelchair would provide a specially designed wheelchair that would be designed to fit over a toilet seat so that the occupant of the wheelchair would not need to move out of the chair in order to use the toilet in a stall. The Comfortable Wheelchair would be constructed from available high quality durable materials of leather, plastic, rubber, wood and metal.
The seat of Comfortable Wheelchair would have an oval hole and can be covered when needed. The cover could be removed by using a tool on both sides of the cover. A Comfortable Wheelchair is disclosed as having two drive wheels and two front castors. The two driving wheels are designed to easily move forward and backward in order that the cover seat be above a toilet seat.

Description

i BACKGROUND AND DESCRIPTION OF' THE INVENTION
Wheelchairs are used by handicapped and disabled persons for a long time ago.
The traditional wheel-chair has a seat with a back, and two large wheels positioned on either side of the seat, which user of the wheelchair can rotate manually in order to drive the wheelchair. The appearance of the Comfortable Wheelchair is similar to existing wheelchairs. The Comfortable Wheelchair would provide greater convenience for users and would be simple to use. It would provide a specially designed wheelchair that would be designed to fit over a toilet seat so that the occupant of the wheelchair would not need to move out of the chair in order to use the toilet in a stall. The wheelchair would measure 22.5 inches to 25 inches in overall height,18 to 20 inches in overall length, 13 to 18 inches in width and three inches in thickness. Other sizes of Comfortable Wheelchair could be made available to consumers. The design of Comfortable Wheelchair calls for leather, plastic, rubber, wood and metal to be utilized as its major components. Comfortable Wheelchair would be blue, black or brown in color.
The wheelchair would have a frame made from sections of stainless steel or aluminum, a seat is suggested to be made from leather in order to provide flexibility during changing position. A backrest is made from wood or plastic and a leather cover. Other features of the wheelchair would include two plastic push handles, four metal wheels with robber tires, push rims and a footrest.
The seat of Comfortable Wheelchair would have a large, oval hole measuring 12.5 inches in overall length and eight and a half inches in overall width. The hole would be kept covered when needed; the cover could be removed by using a tool on both sides of the cover.
The plastic components of Comfortable Wheelchair could be formed with the use of plastic molding techniques such as injection molding or blow molding. Injection molding is a process that has been in use since the 1920s and provides versatility almost unmatched in the mass production of any other material. It requires that melted plastic be forcefully injected into relatively cool molds. As the plastic begins to harden, it takes on the shape of the mold cavity and when cool, requires few post molding operations. Other advantages of this process include its speed of production and its ability to allow multiple parts to be simultaneously molded.
Blow molding in the production of plastic shapes is a form of extrusion, a major technique in the plastics industry. Extrusion is used to push a molten tube, called a parison, into a bottle shaped mold.
Compressed air then forces the parison, into a bottle shaped mold. Compressed air then forces the parison against the cold walls of the mold, hence the teen ''blow molding"
Molds are generally side fed, with the thickness controlled by a tapered mandrel (core) or a variabte-orifice die. Continuous extrusion of the plastic is possible using multiple blow molds.
To use Comfortable Wheelchair, the occupant of the chair would wheel Comfortable Wheelchair into a toilet stall, remove the cover, and use the toilet. Afterwards, the cover could be replaced. The simplicity of the design allows the occupant of the wheelchair to use any public or private toilet since the seat is designed to be above the height of any regular toilet. The wheels are apart enough to go around the toilet seat.
