Abstract
Abstract A manually self transfer device for the unaided self-transfer of an invalid or patient from a bed to a chair, or the like, by sliding along the top surface of the device. A rigid planar surface structure supports the surface in a horizontal plane. The structure is supported at either end by bed, chair, or car seat. Two downhanging members connected to the surface structure snugly fit against a chair side and a bed side to secure the device in place so that the patient may slide unaided from bed to chair.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
161 words
A patient self-transfer device comprising: a. a rigid, planar surface structure to support the surface thereof in a horizontal plane between two juxtaposed objects such as bed and wheelchair; b. two downhanging members each of which is attached rigidly and normal to the supporting surface structure, said members being arranged to contact said objects to secure the structure in position for self-transfer of a patient over said surface from one object to the other object; c. wherein the width of the planar surface is equal to onefourth its length; d. wherein the included angle between the planes of the downhanging members is 40*, and the angle formed on either side of said 40* angle by the major axis of the planar surface structure is 70*; and e. wherein a compression strut is secured to the middle lower portions respectively of the downhanging members therebetween to strengthen the structure because the forces against the outside faces of said members force them inwardly.
