A system comprising a movable device including front wheels and rear wheels configured to swivel and roll, a braking system configured to lock the front wheels and the rear wheels to keep the front wheels and the rear wheels from rolling, a directionally locking system configured to keep the rear wheels from swiveling, first and second rear pedals configured to control the front and rear wheels to be in one of a locked state, a directionally locked state, or a released state, and first and second front pedals configured to control the front and rear wheels to be in one of a locked state or a released state.

An actuation assembly includes a torque input element, a torque output element, and a transfer linkage assembly comprising a connector assembly which connects the input element to the output element. The connector assembly includes a first connector having a proximate end and a connector portion. The proximate end of the first connector is the end closer to either the input element or the output element, and the connector portion is further from that same element. The connector assembly also includes a second connector having a proximate end closer to the other of the input element and the output element. The connector portion is further from that same element. The connector portions are selectively joinable to either permit or resist relative longitudinal translation of the first and second connectors. One example application for the actuation assembly is as an actuation assembly for a braking system on a hospital bed.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.

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.

A brake module (1) of a wheel module (2) has an anchor plate (20) adjacent to a wheel (10) and is indefinitely rotatable about the steering axis (L) with the wheel (10). A lifting unit (30) is fixed adjacent to the anchor plate (20) and fixed about the steering axis (L). A brake wheel (21) is arranged on the wheel shaft (11) and is rotatable about the wheel axis (R) with the wheel (10). At least one transfer element (22, 22) extends from the anchor plate (20) towards the brake wheel (21). The lifting unit (30) is configured to move the anchor plate (20) from a first state to a second state. In the first state, the elements (20, 30, 22, 22) are spaced apart without any contact. In the second state, the at least one transfer element (22, 22) abuts against the brake wheel (21) generating a brake force at the brake wheel (21).

To be self-propelled in a simple configuration and to perform manual operation smoothly and briskly. A driving wheel includes: a base portion; a rotating shaft (first shaft) rotatably provided with respect to the base portion; a rotation member rotatably provided around the rotating shaft; a drive shaft (second shaft) provided on the rotation member orthogonally to the rotating shaft; a drive wheel provided on the rotation member and rotatable around the drive shaft; a drive unit provided on the rotation member and configured to rotationally drive the drive wheel; and a lock mechanism configured to permit rotation of the rotation member with respect to the base portion, and meanwhile, to deter the rotation of the rotation member with respect to the base portion.

A brake device for a swivel caster has high durability with a simple power transmission structure, wherein a brake shoe is disposed so as to face a peripheral surface of a wheel of the swivel caster, a cable connected to an operation lever is inserted into a pivot shaft of the caster to be connected to the brake shoe, and a ball chain is interposed at least in a part of the cable inserted into the pivot shaft.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.

A piece of luggage including a main body and a power supplying module is disclosed. The main body includes a moving module including a plurality of wheels and a main motor and a power unit electrically connected to the moving module. The wheels include an active wheel electrically connected to the main motor. The power supplying module includes a power supplying unit including a power supplying box and a battery and a connecting unit including a connecting part, a holding part and a conducting wire. The power supplying box has an output port. The battery is disposed in the power supplying box and electrically connected to the output port. The connecting part has a power port corresponding to the output port. The holding part and the conducting wire are connected to the connecting part. The conducting wire is electrically connected to the power port and the power unit.

A chassis of a transportable device including a base structure, four casters arranged thereon, four lowerable and raiseable support feet also mounted on the base structure, and a hydraulic support foot actuating device. The hydraulic support foot actuating device has a reservoir (1), a pump (2) manually operable by hand or foot, four support foot linear actuators (3) and a purely hydro-mechanical pipe and valve arrangement (4) which connects the reservoir (1), the pump (2) and the linear actuators (3) to one another. Therein, by means of hydraulic fluid delivered by the pump (2) from the reservoir (1) the two support feet assigned to two primary linear actuators (3a) can be fully extended until a mechanical stop is reached while raising the base structure by first applying pressure to the two primary linear actuators (3a) before applying pressure to the two other, secondary linear actuators (3b).
