Patent ID: 7340784

Claim:
A patient transfer device for pull-up, rollover and transfer of a patient disposed on a sheet, comprising: a base assembly including one or more wheels for movement of the base assembly; a power train mounted within the base assembly; a clamping and strap assembly including at least one strap attachable to the power train, a retractor bar attachable to the at least one strap and at least one clamping device pivotally attached to the retractor bar and releasably attachable to the sheet, the at least one clamping device including a clamp receiver, a clamp bar, a clamp handle pivotally connected to the clamp receiver and pivotal between a clamping position and a non-clamping position, wherein the receiver includes a concave surface for engagement by the clamp bar, and a compression assembly eccentrically pivotally connected to the clamp handle and pivotal between a clamping position and a non-clamping position, the compression assembly including a bight portion for engaging a clamping face of the clamp receiver and a pair of arm portions for pivotally connecting to the clamp handle, wherein the compression assembly is adapted to movably engage the clamp bar with the clamp receiver; a power and switching system in electrical communication with the power train; a vertical adjustment assembly operably adjoined between the base assembly and the clamping and strap assembly for adjusting the vertical position of the clamping and strap assembly, the vertical adjustment assembly including a pair of upstanding rails and a pair of upstanding sleeves slidably receiving the rails, the rails including a plurality of spaced indentations defining a plurality of vertical positions of the clamping and strap assembly, and at least one of the sleeves including a positioning mechanism for releasably locking the clamping and strap assembly at one of the plurality of vertical positions; and wherein the vertical adjustment assembly further comprises a standoff assembly, the standoff assembly projecting outwardly from the upstanding rails to thereby increase the travel distance off the clamping and strap assembly.
