Abstract: A coupling device includes base and plate members that are connectable to one another. The base member has a body with a coupling face, a stopper connected to the body and moveable between neutral and locked positions, and an actuation mechanism for moving the stopper. In a connected mode of the coupling device, a contact portion of the coupling face contacts a contact face of the plate member, and an alignment area of the contact portion corresponds to a position of an opening of the plate member. In the neutral position, the stopper is aligned with the alignment area and can be received in the opening thereby permitting removal of the plate member from the base member. In the locked position, the stopper is misaligned with the alignment area, and extends over a part of the plate member to restrict movement of the plate member away from the base member.

Abstract: The invention relates to a wheel assembly for a patient support apparatus comprising a fixed portion, a pivoting portion attached to the fixed portion and a wheel operatively connected to the pivoting portion, the wheel, which can be motorized, being movable between a first deployed position and a second retracted position. The wheel assembly has a spring assembly for urging the wheel in the first deployed position and an actuator to raise the wheel in the second retracted position. The invention also relates to a control handle for a motorized bed comprising a handle member having an actuatable trigger for controlling propelling of the bed, the handle member further comprising a user interface configured for providing bed information to the operator.
