Abstract
Abstract The chair of a transfer bench includes hooks for selectively engaging and disengaging the seat from supporting tracks. Rollers attached to the chair allow the chair to move on the tracks. The bench portion comprises a pair of parallel tubular tracks supported by legs. A pair of safety hooks attached to the underside of the chair loosely engage the tracks and keep the chair from tipping. The legs are normally locked in the open position. For storage purposes it is possible to unlock the legs and fold them up against the track unit. A genital guard is provided on the underside of the seat to insure patient comfort and protection. The apparatus allows the user to transfer into and out of a bathtub or shower with a minimum of inconvenience and a maximum of security.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
A transfer bench apparatus comprising: a chair; at least four roller means attached to the underside of said chair; a bench including track means comprising at least two substantially parallel and substantially equally long tubular tracks for supporting said roller means attached to said chair, said two tracks defining a space therebetween, said bench further including leg means for supporting said track means; and, releasable means attached to said chair for loosely engaging at least one of said tubular tracks thereby preventing said chair from falling off of said bench, wherein said chair faces away from the space between said two tubular tracks and wherein said releasable means can be disengaged from at least one of said tubular tracks thereby completely disengaging said chair from said bench and allowing said chair to be rotated by 180° in a plane parallel to said tubular tracks and re-engaged with said tubular tracks facing in the opposite direction from its previous engagement.
Claim 2
Dependent Claim
159 words
A transfer bench apparatus comprising: a chair; at least four roller means attached to the underside of said chair; a bench including track means comprising at least two substantially parallel and substantially equally long tubular tracks for supporting said roller means attached to said chair, said two tracks defining a space therebetween, said bench further including leg means for supporting said track means; and, releasable means attached to said chair for loosely engaging at least one of said tubular tracks thereby preventing said chair from falling off of said bench, wherein said chair faces away from the space between said two tubular tracks and wherein said releasable means can be disengaged from at least one of said tubular tracks thereby completely disengaging said chair from said bench and allowing said chair to be rotated by 180° in a plane parallel to said tubular tracks and re-engaged with said tubular tracks facing in the opposite direction from its previous engagement.
Claim 3
Dependent Claim
37 words
