ABSTRACT:
A patient transfer device comprises a belt connected at its ends to first and second reels and in its extension from the first reel to the second reel defines in turn an upper patient supporting portion and a lower ground engaging portion. Each of said reels is selectively rotatable so that in a first mode of operation of the transfer device with said first reel driven the belt is taken-up by the first reel and let out by the second reel and in a second mode of operation the belt is taken up by the second reel and let out by the first reel. An auxiliary belt take-up and let-out device is connected to the belt at a position between its upper patient supporting portion and its lower ground engaging portion and is selectively lockable to enable the first and second modes of operation to be performed. With said first reel locked said auxiliary device can be driven so that in a third mode of operation the belt is taken up by the auxiliary device and let out by the second reel and in a fourth mode of operation rotation of said second reel with said auxiliary device unlocked the belt is taken up by the second reel and let out by the auxiliary device. The first and second reels and the auxiliary device are provided with driving shafts to which a manually operable driving handle can be individually fitted. The locking and unlocking of the first reel and the auxiliary device is effected automatically by the fitting of the handle to respective driving shafts for effecting a take-up operation of the second reel in the second and fourth modes of operation.
