The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.

A caster system, including a housing portion, which includes first and second side walls defining an operational space therebetween and an upper wall including a central bore. A rolling assembly is disposed in the operational space, and is rotatable relative to the housing. The rolling assembly includes an exterior rim formed of a resilient material having at least one coloring agent embedded therein. A vertical connection assembly includes a shaft adapted to be fixed to a furniture article and to extend through the central bore in the upper wall. The housing portion is rotatable about the shaft of the vertical connection assembly. The coloring agent is adapted to be luminescent or phosphorescent in a dark environment.

In a method for monitoring an electromagnetically actuable brake, which has an energizable coil that interacts with a tractive electromagnet situated so as to be linearly movable, and a vehicle having an electromagnetically actuable brake, the current flowing through the coil is acquired, the acquired current value in particular being conveyed to an evaluation unit, the voltage applied at the coil is intermittently increased, and a relative position of the tractive electromagnet with respect to the coil is determined from the thereby induced current characteristic, in particular the characteristic of the current rise, it is particularly determined from the ascertained position whether the brake is in the applied state or in the released state, the tractive electromagnet in particular is arranged as a permanent magnet or has a permanent magnet.

An offset caster is described. The offset caster includes a wheel, an axle connected to the wheel, and an offset base connected to the axle. The offset base is offset by a distance. The offset base includes a connection to a computing device support. Computing device supports that include at least one offset caster are described. Systems for moving a computing device that include a computing device and a computing device support with at least one offset caster are described.

A hollow caster structure includes a base, a caster body pivotally connected with the base, a first wheel unit mounted on the caster body, and a second wheel unit mounted on the caster body. Each of the first wheel unit and the second wheel unit forms a viewing space. Thus, the viewing space of each of the first wheel unit and the second wheel unit provides a visible effect. In addition, the hollow caster structure has a lighter weight by provision of the viewing space. Further, the parts of the hollow caster structure have different colors which are visible from the viewing space.

A caster includes a caster unit and at least one braking unit. The caster unit includes a receptacle, a wheel shaft disposed through the receptacle, a wheel assembly sleeved on the wheel shaft and rotatable relative to the receptacle, and a spring assembly which acts on the receptacle and the wheel shaft. The receptacle is movable relative to the wheel assembly in a vertical direction. The braking unit includes a surrounding teeth structure formed on the wheel assembly and having a hardness ranging from 65 to 75 on a Shore D scale, and a braking piece mounted on the receptacle. The braking piece includes a braking surface in form of a curve surface having a hardness ranging from 40 to 46 on the Shore D scale to be engaged with the surrounding teeth structure to retard rotation of the wheel assembly.

A subject support lift includes a mast portion, a base portion, and a lockable wheel assembly coupled to the base portion. The lockable wheel assembly includes an axle member, a lockable wheel coupled to the axle member, and a pivot member pivotally coupled to the lockable wheel and defining an axis extending in a vertical direction, where the lockable wheel is rotatable about the axis defined by the pivot member. A locking member is coupled to one of the pivot member or the lockable wheel, the locking member being repositionable between a locked position, in which the locking member engages the other of the pivot member or the lockable wheel, and an unlocked position, in which the locking member is spaced apart from the other of the pivot member or the lockable wheel.

A wheel shock absorption structure and a child carrier having the wheel shock absorption structure, including a wheel shaft and a wheel seat connected with a frame, and a lower end of the wheel seat is rotatably connected with a wheel through the wheel shaft. Further including a shock absorber with an elastic structure, an upper end of the shock absorber is removably connected with an upper end of the wheel seat, and the shock absorber rotates synchronously along with the wheel seat; a lower end of the shock absorber is rotatably connected with the wheel shaft which is slidably connected with the lower end of the wheel seat. The shock absorber is driven by sliding of the wheel shaft to generate recoverable elastic deformation to provide damping and buffering. The bending deformation of the shock absorber ensures that the wheel shock absorption structure has a better shock absorbing effect.

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 arraigned 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.
