Abstract: A structure and apparatus for engaging and disengaging an electric motor for a power assisted patient transporter. The motor is allowed to slide, along a guide (in one embodiment an elongated slot) on a unitary structure installed on the transporter, to be engaged or disengaged from a lead screw. A key mechanism is provided to lock the motor in either an engage position or a disengage position.

Abstract: A compact, lightweight, power lifting unit assists the operator of a mobile patient transporter in raising or lowering the patient bed to the desired height required in transporting or transferring a patient. The power lifting unit may also be used to "collapse" the transporter to its lowest height. The power lifting unit is adaptable and may be installed on virtually any existing "X" frame transporter. Electronic controls allow a single operator to raise or lower the patient bed or allow the patient bed to coast gently to a rest position. In particular, in one embodiment the power lifting unit includes a jog pulse circuit that prevents operators from jamming the transporter. In another embodiment, the power lifting unit includes a jog-off high limit circuit that prevents operators from attempting to raise the transporter beyond its maximum height. In yet another embodiment, a power lifting unit includes a low battery detection circuit that provides both an audible and a physical indication (i.e.

Abstract: A compact, lightweight, power lifting unit assists the operator of a mobile patient transporter in raising or lowering the patient bed to the desired height required in transporting or transferring a patient. The power lifting unit may also be used to "collapse" the transporter. The power lifting unit uses a ball screw and ball nut to convert the rotary motion of an electric motor to the linear motion necessary to drive a tension arm and raise or lower the transporter. The power lifting unit is adaptable and may be installed on virtually any existing transporter.

Abstract: A lightweight, compact power lifting unit has one or more tension arms for applying the force required to adjust the height of a "gurney" or mobile patient transporter. In one embodiment, a ball screw and nut are used to drive the tension arms, reducing both the weight and the power requirements of the power lifting unit. The power lifting unit is adaptable to being installed on existing transporters.
