A hospital bed, trolley or lifter includes a steering wheel mounted on a wheel support arm extending from which is a ratchet mechanism which can co-operate with a tooth of an adjustment mechanism. When the tooth is engaged in the ratchet teeth of the ratchet mechanism the wheel can be raised and held in the raised position until the tooth is disengaged. The wheel adjustment mechanism also includes an eccentric wheel for raising the tooth in a periodic manner to cause periodic raising of the wheel. A damper is attached to the support arm for dampening the drop of the wheel when the tooth is disengaged. A mechanism provides a steering wheel which can be held at intermediate positions between its uppermost and lowermost positions and which can be held in an engaged position in a plurality of different positions relative to casters of the bed or trolley. The system can also make use of a small capacity drive motor whilst still retaining speed of operation.

Wheel drive mechanism for patient handling equipment

Patient handling equipment, such as a hospital bed, is provided with a propulsion system and a status indicator light system incorporated in the propulsion system and operable to generate at least two light beams beyond a perimeter of the bed. The light indicator, which may have different colors, shapes or intensities, can indicate the state of propulsion of the system and generates light beams which are visible all around the equipment so as to be visible to a carer from any angle. The apparatus may include an ambient light sensor disposed to detect floor level lighting conditions rather than general ambient light.

Status light assembly for patient handling equipment

A brake assist system for patient handling equipment such as a patient bed includes a drive wheel. The wheel includes a brake assist system operated by control of a controlled unit which is operable to sense tilt of the handling equipment and to apply partial breaking to the wheel when it is detected that the equipment is on a slope. The control unit controls a maximum speed of the equipment down the slope, in order to protect the patient and to assist a care worker. The control unit disengages the brake assist mechanism when it is detected that the equipment is on a horizontal surface.

Brake assistance system for patient handling equipment

An assisted propulsion system, method and chassis for conveying a payload along a surface are described. A plurality of wheels disposed about the chassis support it on the surface. A drive provides at least assisted propulsion to the chassis along the surface. At least a driving part of the drive is connected to the chassis via a mount having a resiliently sprung link. At least the driving part of the drive has a fixed orientation and is moveable independently of the chassis and the plurality of wheels in a direction towards the surface. The resiliently sprung link is arranged to direct at least the driving part onto the surface during provision of the assisted propulsion. A sensor is arranged to monitor acceleration of the drive and to communicate data on acceleration to a controller, which controls operation of the drive in dependence on the data received from the sensor.
