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.

Powered patient support apparatusessuch as beds, cots, stretchers, or the likeinclude a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.

Systems and methods for facilitating movement of a patient transport apparatus. The patient transport apparatus has a support structure and a patient support surface. Caster assemblies are coupled to the support structure to roll about a roll axis and swivel about a swivel axis. A control system is configured to control brake mechanisms, steer-lock mechanisms, and pre-swivel mechanisms of the caster assemblies based on one or more inputs.

Systems for facilitating movement of a patient transport apparatus are provided and include user input control device that includes a mode switch selectable between a longitudinal transport mode and a multidirectional mode and a driving assist device actuatable between at least one engaged state and a non-engaged state. The mode switch generates signals based on the selected mode and the driving assist device generates engaged or non-engaged signals which are received by a controller. The controller is configured to generate an output signal sent to a lift actuator, swivel actuator, and/or a powered drive system to assist a user in propelling the apparatus in a desired manner.

A mobile support such as a stretcher includes a left rear rolling element and a right rear rolling element. The support also includes a sensor system adapted to sense displacement force applied to the support, and a deceleration system. Provided the bed is moving in a forward direction, machine readable instructions executed by a processor cause the deceleration system to apply a decelerating influence to selected members of the set of rolling elements in response to the sensed displacement force in order to assist braking and steering maneuvers.

An occupant support system includes a base frame, an upper frame raisable relative to the base frame, and a deck supported by the upper frame configured to support an occupant. A plurality of casters including left and right side casters supports the base frame and are configured to facilitate movement of the occupant support system. Electrically-driven deceleration systems are configured to provide a force to the left and right side casters. Left and right push handles that each have a grip portion are configured to be gripped by a caregiver to provide the movement. A control system is configured to cause the electrically-driven deceleration systems to apply forces selectively to the left and right side casters. The control system includes a processor and a memory that includes instructions, which, when executed by the processor, cause the control system to selectively apply the forces to the electrically-driven deceleration systems.
