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 system includes (i) a caster having a first stem portion with a first stem portion connection configuration; and (ii) a set of second stem portions having an identical second stem portion connection configuration but having outer dimensions differing from outer dimensions of another second stem portion in the set of second stem portions. The caster first stem portion connection configuration is adapted to mate with the second stem portion connection configuration of the second stem portions in the set of second stem portions.

A multi-functional active container (e.g., luggage or suitcase) with a plurality of sensors and actuators is described. The container may include a body defining an enclosure and having at least one opening. The container may include a processor, a wireless receiver, and an electronically controllable lock. The processor can selectively lock or unlock the electronically controllable lock based on signals received via a wireless receiver (e.g., via Wi-Fi or BLUETOOTH connections). In some examples, a distance between the active container and a remote device (e.g., a smart phone) can be determined (e.g., based on relative GPS signals or connection strength) and if the distance exceeds a threshold, the electronically controllable lock can be activated to secure the container. Further, the container may include a rechargeable power source for powering external devices and an integrated weight sensor for detecting the weight of the container.

A transportable carton assembly is disclosed that includes a carton defining a bottom rear corner edge portion having a pair of longitudinally spaced apart apertures formed therein, and an elongated shield retained within the bottom rear corner edge portion of the carton and including a pair of longitudinally spaced apart wheels positioned to extend through the longitudinally spaced apart apertures formed in the bottom rear corner edge portion of the carton for transporting the carton over a surface.

Particular embodiments disclosed herein provide a retractable guard assembly coupled to a caster of a mobile equipment, comprising a housing and one or more guards at least partially disposed in the housing. The one or more guards are independently movably coupled to the housing. The retractable guard assembly further comprises corresponding one or more biasing elements coupled to the one or more guards and to the housing for biasing the one or more guards towards a fully deployed state. When the one or more guards are in the fully deployed state, contact between a fixed object and a portion of the one or more guards disposed outside the housing causes the one or more guards to transition into a retracted state, and when the contact is removed, the corresponding one or more biasing elements cause the one or more guards to transition into the fully deployed state.

It is described herein a table which may comprise a panel (100), a first extendable leg (200), a second extendable leg (300), a first foot (400), a second foot (500), and a control assembly (600). The first extendable leg may be connected at a first end to a bottom surface of the panel adjacent to a first edge of the panel. The second extendable leg may be connected at a first end to the bottom surface of the panel adjacent to a second edge of the panel opposite the first edge of the panel. The first extendable leg may be connected at a second end to a top surface of the first foot. The second extendable leg may be connected at a second end to a top surface of the second foot. The first foot may further comprise a pair of first casters connected to a bottom surface of the first foot. The second foot may further comprise a pair of second casters connected to a bottom surface of the second foot. At least one of the first extendable leg and the second extendable leg may further comprise a linear actuator electrically connected to a battery of the control assembly.

A smart wheel is provided, including a main body, at least one wheel body and a GPS module. The main body includes a pin and a wheel seat, and the wheel seat is connected with the pin. The at least one wheel body is pivoted to the wheel seat along an axial direction. The GPS module is arranged on the main body and includes a GPS chip.

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 pallet with wheels and breaking system, that can be interlocked with other pallets. The pallet has five sets of wheels that can be locked or unlocked using the fork rubber or pressing a switch. The wheel breaking system includes a fork breaking rod, wheel transfer gear wheel, wheel transfer rod, wheel braking pin, wheel transfer gear wheel bearing, wheel rotating bearing, and wheel breaking pin springs. The pallet has locking rings around the perimeter, allowing the pallet to interlock with other pallets by pressing a switch. The locking ring locking system includes a locking ring transfer gear wheel, locking ring transfer rod guide, locking ring transfer rod, locking ring ball engaging rod, locking ring ball guide, locking ring ball pusher, and locking ring ball. The pallet further includes corner bumpers, load stabilizers, wheel insets, and shelf rack bars that can be extended for additional support and shelving units.
