A surgical patient support includes a foundation frame, a support top, and a brake system. The foundation frame includes a first column and a second column. The support top is coupled to the first column and the second column for rotation about a top axis extending along the length of the support top.

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.

An overbed table may have a base support frame with at least three casters and a rechargeable battery. A motor housing with a top wall having an opening may be attached to the base support and a telescoping column that is hollow tubular is attached at a bottom end to the motor housing over the opening to extend upwardly. A linear motor is positioned in the motor housing with a linear motor actuator projecting through the opening and into the telescoping housing wherein an extension member of the linear motor actuator is attached at a top end to a slidable table column member of the telescoping housing. Servo housing is attached at a top end of the slidable table column member with a servomechanism attached in the servo housing positioned for a rotating shaft of the servomechanism to engage a circular bracket attached adjacent to a first end of a table wherein the circular bracket is rotatably engaged with the servo housing. The rechargeable battery is in electrical communication with a control processor of a control panel attached adjacent the first end of the table, to the linear motor and to the servomechanism.

A person support apparatus includes a base frame with a plurality of caster wheel assemblies, each of the caster wheel assemblies including a caster brake actuator movable between a total braking position and a non-braking position. A linkage system is coupled to the caster brake actuators for controlling the caster brake actuators and is operable to move the caster brake actuators between their total braking positions and their non-braking positions. The linkage system is configured to compensate for tolerances in the linkage system wherein the linkage system can control the caster brake actuators to simultaneously move between their total braking positions and their non-braking positions.

A collapsible stroller includes a stroller frame, at least one hinge mechanism, a wheel, and a swivel mechanism. The stroller frame is moveable between a deployed position and a collapsed position. The hinge mechanism allows for movement of the stroller frame between the collapsed position and the deployed position. The swivel mechanism connects the wheel to the stroller frame. The swivel mechanism includes a vertical axle, a cam follower, and a cam. The vertical axle connects with the wheel and is rotatable with respect to the stroller frame about a vertical axis. The cam follower is fixed to the vertical axle. The cam includes a sloped cam surface at least partially surrounding the vertical axle. The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.

A lockable swivelable caster provides for an interaction between a centering element and a locking element to pivotally urge the locking element into a locking notch of the centering element such that the locking element is captured by the locking notch to prevent swiveling of the caster wheel.

The sloped cam surface contacts the cam follower to move the cam follower along the sloped cam surface, which results in rotation of the vertical axle about the vertical axis.

A selectively operable steering locking mechanism includes front and back pivot locks, each respective one selectively movable between: a locked configuration whereat a respective front, or back, caster of the cart is precluded from pivoting about its vertical axis; and an unlocked configuration whereat the respective front, or back, caster is free to pivot its vertical axis. An interconnection mechanism interconnects the front and back pivot locks for synchronized movement between: a front-locked steering configuration whereat the front and back pivot locks are in the locked and unlocked configurations respectively; and a back-locked steering configuration whereat the front and back pivot locks are in the unlocked and locked configurations respectively. A control mechanism connects to the interconnection mechanism for its selected movement between the front-locked and back-locked steering configurations. A cart provided with the selectively operable steering locking mechanism is also disclosed.

The present disclosure in at least one embodiment provides a corner module for a vehicle, including a front-wheel corner module configured to drive a front wheel and including a front-wheel inwheel motor installed on the front wheel to generate a driving force and a friction braking device configured to generate a braking force on the front wheel, a rear-wheel corner module configured to drive a rear wheel and including a rear-wheel inwheel motor installed on the rear wheel to generate a driving force, a driving information detector configured to detect driving information of the vehicle, and an electronic control unit configured to control the front-wheel corner module to form a friction braking force by using the driving information and to control the rear-wheel corner module to form a regenerative braking force, wherein the front-wheel corner module uses the front-wheel inwheel motor that is provided with a lower specification than the rear-wheel inwheel motor to save the manufacturing cost, and the rear-wheel corner module has no friction braking device installed so that the rear-wheel inwheel motor is undamaged by heat.

A support arrangement having an activation mechanism to control the movement of wheels is provided. The support arrangement includes a platform, a chassis attached to the platform, a pair of wheel assemblies movably coupled to the chassis, and the activation mechanism. The pair of wheel assemblies are operable between a first state and a second state. The activation mechanism includes a track having a first stable position and a second stable position spaced along a length of the track, and a pin configured to travel along the track. Wheels are in the first state when the pin is in the first stable position and are in the second state when the pin is in the second stable position.
