Vehicle for Carrying a Disabled Person

Many disabled persons use wheelchairs to travel from one place to another and to serve as a platform in order to accomplish work tasks, Unfortunately, constant pressure on the buttocks area of the users causes decubitus sores which require medical treatment. Certain support frames have been devised to place a disabled person in a standing position in order to eliminate the disadvantages of a wheelchair, prior discussed. For example, standing frames such as the Grandstand manufactured by Prime Engineering of Fresno, California, the Lifestand manufactured by L.D.C. Corporation of Folcroft, Pa., and a similar device manufactured by Altimate Medical, Inc., are exemplar of such devices. Although relieving pressure on the buttocks area, the standing frames heretofore described can only be employed for a limited time period before the user tires.

Many support frames have been devised to perform work which are not necessarily intended to be used by disabled persons. For example, U.S. Pat. No. 4,863,178 shows a movable support frame which permits a mechanic to stand on a platform and rest their mid-section on a cushion in order to work on items below the cushion.

U.S. Pat. No. 4,397,374 includes a T-shaped mobile frame with a standing platform and a chest support platform which may be used together to permit the mechanic to work on an engine compartment.

U.S. Pat. Nos. 3,037,570 and 4,832,407 show seats which are used in conjunction with chest supports to permit the user to remain in a sitting position and leaned forward to perform work beyond the chest support area.

U.S. Pat. Nos. 3,976,155 and 4,394,049 depict kneeling platforms used in conjunction with chest supports and work platforms for gardening and tiling.

A vehicle for carrying a disabled person in a kneeling position in order to perform work tasks would be a notable advance in the medical field.

In accordance with the present invention a novel and useful vehicle for carrying disabled persons along a surface is herein provided.

The vehicle includes as one of its elements, a base member linked to transporting means for permitting the base member to move along a surface. The transporting means may take the form of wheels, skids, skis, and the like. The base member may also be formed of any rigid or semi-rigid material and include a padded surface to permit the person using the vehicle to kneel on the same.

A torso support is also provided for in the present invention and is connected or linked to the base member. The torso support extends upwardly and outwardly from the base member and may be provided with adjustment means for determining the particular angle of orientation relative to the base member. The torso support may be constructed with a padded surface to render comfort to the chest area of the user.

The vehicle of the present invention is also provided with a thigh support which is positioned intermediate the base member and the torso support. The thigh support includes a first portion and an opposing second portion which are intended to constrain the thigh of the user and maintain a comfortable kneeling position of the user of the vehicle. The thigh support may be adjustably positioned relative to the base member and may be rotated into position against the thigh of the user.

Transporting means may be provided with an axle extending transversely relative to the base member. A pair of wheels in certain instances may be rotatably connected to the axle and sized to allow manual turning of the same by the disabled person resting on the torso support. In certain embodiments, a caster may also be employed beneath the base member and spaced from the pair of wheels to form a tricycle transporting means.

A tray may also be found in the present invention and extend from a pair of uprights which connect the base member to the torso support. The tray would extend horizontally at a level lower to the surface than the torso support in order to permit the user of the vehicle to conveniently access the tray during the performance of work tasks.

It may be apparent that a novel and useful vehicle for carrying a disabled person along a surface has been herein described.

It is therefore an object of the present invention to provide a vehicle for carrying a disabled person which easily and comfortably supports a disabled person in an upright kneeling position in order to perform work tasks.

Another object of the present invention is to provide a vehicle for carrying a disabled person which includes transporting means that is manually manipulated by the user, such as a pair of wheels located along an axle.

Yet another object of the present invention is to provide a vehicle for carrying a disabled person which eliminates the need for the disabled person to assume a sitting position and, thus, avoids the development of sores on the buttocks area.

Yet another object of the present invention is to provide a vehicle for carrying a disabled person which easily manufactured and transported to a place of work.
