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 running wheel for a patient positioning device (30) is provided. The running wheel has a wheel (1) and a receiving device (4) for rotatably receiving the wheel (1) around a first rotational axis (5), which is arranged centrally with respect to a circumference of the wheel (1). The wheel (1) has a wheel body (3), and multiple circumferential castors (7), each having a second rotational axis (8) arranged in a direction tangential to a circumference of the wheel (1), wherein the circumferential castors (7) form a bearing surface of the wheel (1).

A caster may include a shaft, a first elastic ring, a C-shaped ring, and a second elastic ring. The shaft has one end inserted and secured in a wheel, and a first rod is extended from the other end of the shaft, and a second rod protrudes from an end of the first rod. The diameter of the first rod is larger than that of the second rod, and an end of the second rod comprises a flexible portion. The shaft only needs to be processed to form the second rod and the flexible portion, and the first elastic ring and the second elastic ring which are identical are adapted to be formed through the same mold so as to save the manufacturing cost.

An article of furniture has retractable and extendable wheels secured beneath each leg. The mechanism for retraction and extension is accomplished by an activation means in mechanical communication with each wheel.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arranged to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

Provided are a truckle structure and a cabinet. The truckle structure comprises: a truckle and a support, wherein the truckle includes a mounting base and a wheel rotatably mounted on the mounting base; the support is composed of a mounting portion located at a lower middle position as well as two connecting portions respectively located on two sides of the mounting portion; the two connecting portions are formed in a manner that the left side and the right side of the mounting portion are upwards bent towards the middle, the support is rotatably connected to the mounting base through the two connecting portions, and the mounting base is located between the two connecting portions; and a mounting hole is formed in the mounting portion, center of the mounting hole and center of gravity of the truckle are on a same straight line, and center of gravity of the support deviates from the straight line. The truckle structure can be directly mounted on the ground and is firmer and more durable.

In a heavy duty orbital caster assembly that includes a rotatable wheel unit joined to a transfer plate that pivots about a mounting post extending from a mounting plate adapted to be secured to the bottom surface of an object, the improvement comprising a pair of roller bearing assemblies that extend upwardly from the upper surface of the transfer plate adjacent to the caster wheel post as it extends through its bearing. The rollers impinge on the lower surface of the mounting plate, and serve to transfer some of the load of the supported object directly to the caster wheel, enabling the support of very heavy loads.

A castor with a brake pad is disclosed, wherein the fixing sections and the pressing sections of the brake pad press against the two wheel-side portions of the wheel body, so in addition to providing friction, it can also provide clamping function, as a result, the braking effect can be achieved more easily, and the braking force tends to be even. Furthermore, because the fixing sections and the pressing sections of the brake pad press against the two wheel-side portions instead of pressing against the center of the wheel body, so no extra resistance is generated, and there is no excess wear, thereby extending the service life of the wheel body.

A sterilization cabinet, comprising a top panel, at least two side panels, and a floor panel forming a part of a chamber of the sterilization cabinet; at least one door connected to at least one of the at least two side panels of the sterilization cabinet; a vent formed in at least one of the two side panels; at least one first filter covering the vent and a filter cover configured to hold the first filter against the vent; a drain positioned in the floor panel, wherein the floor panel has a slope configured to cause condensate within the chamber to flow into the drain and wherein the drain is the only outlet for the condensate along the floor panel; and a second filter covering the drain such that condensate flowing into the drain passes through the second filter.
