An electronic gaming machine includes a cabinet having an internal frame and a pair of retractable wheel assemblies mechanically coupled to the internal frame. Each retractable wheel assembly includes a first retractable wheel, and a second retractable wheel. The first retractable wheel and the second retractable wheel are movable between a retracted position and an extended position. The first and second retractable wheels of each of the pair of retractable wheel assemblies support the cabinet above an external surface when each are in the extended position, thereby facilitating movement of the cabinet across the external surface. Further, the first and second retractable wheels of each of the pair of retractable wheel assemblies allow the cabinet to contact the external surface when each are in the retracted position.

A foot pedal assembly and method of moving a wheel assembly from a stowed configuration to a deployed configuration is provided. The foot pedal assembly can be moved to a locked configuration, thereby securing the wheel assembly in a deployed configuration, by allowing a foot pedal of the foot pedal assembly to move away from a second position after moving the foot pedal from a first position to the second position. When in the locked configuration, the foot pedal assembly can be moved to an unlocked configuration by moving the foot pedal assembly back to the second position, thereby allowing the foot pedal assembly and the wheel assembly to move towards the first configuration and the stowed configuration, respectively. A pin extending from a cam assembly into a raceway of a raceway body travels through the raceway as the foot pedal assembly is moved between configurations.

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support frame to influence motion of the patient transport apparatus over a floor surface. The auxiliary wheel is movable to a deployed position with the auxiliary wheel engaging the floor surface and a stowed position with the auxiliary wheel spaced a distance from the floor surface. An actuator assembly including a lift actuator a biasing device, and a biasing load adjustment assembly. The lift actuator is operable to move the auxiliary wheel to the deployed position and to the stowed position. The biasing device configured to bias the auxiliary wheel towards the deployed position. The biasing load adjustment assembly configured to adjust a biasing force being applied by the biasing device to the auxiliary wheel.

A stand for a touch screen device, including a base including at least two wheels, wherein the wheels are retractable within the base. The stand also includes a frame including a first end and a second end, attached by its first end to the base. Furthermore, the stand includes a support for the touch screen device, attachable to the frame at the proximity of the second end of the frame. The support includes means for rotating the support with respect to the frame and means for locking the support with respect to the frame. The stand also includes a battery and means for connecting the battery to the touch screen device.

A foldable bicycle contains: a front frame, a rear frame, and a folding device. The front frame includes a front fork connected on a front wheel, and the rear frame includes a rear fork connected on a rear wheel and includes a seatpost coupled with a connection post and a saddle. The folding device is rotatably connected between the front frame and the second frame. The front fork has a sole column, the front wheel is inserted through a hub by using a hollow hub shaft to connect with the sole column, and the hollow hub shaft has a first connection element defined in a central portion thereof The rear wheel has a second connection element extending outward from a central portion thereof so as to fit with the first connection element after folding the front wheel and the second wheel.

A caster wheel assembly includes a frame configured to pivotally couple to a tool bar, a sub-frame rotatably coupled to the frame, and a connecting linkage configured to control movement of the frame relative to the tool bar. The caster wheel assembly also includes a locking assembly, which includes a lock lever movably coupled to the frame, wherein the lock lever includes a locking element and a release element, a locking structure fixedly coupled to the sub-frame, and a driving element fixedly coupled to the connecting linkage. The locking element is configured to block rotation of the sub-frame relative to the frame while the locking element is engaged with the locking structure, and the driving element is configured to contact the release element as the connecting linkage moves the frame downwardly relative to the tool bar to drive the locking element to disengage the locking structure.

A wheel dolly for raising a vehicle wheel off the floor is disclosed. The dolly has at least two wheel straddle bars, each straddle bar having a non-swing caster assembly. A swing caster assembly is connected to each straddle bar. The assembly includes a stationary frame supporting a swing axle, a swing frame that rotates about the swing axle, and a swing caster connected to swing frame. The swing caster defines a swivel plane. A lift bar connects the two wheel straddle bars. The dolly can transition between two configurations: a lowered configuration, wherein the swivel plane is not parallel to the floor, and a raised configuration, wherein the swivel plane is substantially parallel to the floor.

A telescoping wheel assembly includes a base body, a wheel set and an elastic member. The base body includes a receiving groove. The wheel set is connected to the receiving groove and selectively positioned at an outward position or an inward position relative to the receiving groove. The wheel set includes a wheel axle and a wheel body. The wheel body is connected to an outside of the wheel axle. The elastic member is disposed in the receiving groove and abutted against the base body and the wheel set. When the wheel set is positioned at the outward position, the elastic member provides a buffering elastic force to the wheel set. When the wheel set is positioned at the inward position, the elastic member provides a pushing elastic force to the wheel set.

An electronic gaming machine includes a cabinet having an internal frame and a pair of retractable wheel assemblies mechanically coupled to the internal frame. Each retractable wheel assembly includes a first retractable wheel, and a second retractable wheel. The first retractable wheel and the second retractable wheel are movable between a retracted position and an extended position. The first and second retractable wheels of each of the pair of retractable wheel assemblies support the cabinet above an external surface when each are in the extended position, thereby facilitating movement of the cabinet across the external surface. Further, the first and second retractable wheels of each of the pair of retractable wheel assemblies allow the cabinet to contact the external surface when each are in the retracted position.

A mobile imaging device includes a base having at least one caster, a first drive mechanism that moves the system in a transport mode and translates an imaging component relative to the base in a scan mode, and a second drive mechanism that extends caster relative to the base to raise the base off the ground in the transport mode, and retracts the caster relative to the base to lower the base to the ground in the scan mode. A caster system for a mobile apparatus includes a base containing a housing and a caster, attached to the base, the caster having a wheel defining a wheel axis and a swivel joint defining a swivel axis and a pivot point defining a pivot axis, wherein the caster pivots on the pivot axis as the caster is retracted into the housing and extended out of the housing.
