A system for supporting or positioning a patient before, during, or after a medical procedure can include a platform configured to support at least a portion of a patient. A support column can be positioned beneath the platform. A base can be positioned beneath the support column and configured to support the support column. The base can include at least one drive wheel configured to contact a ground surface and move the platform with respect to the ground surface. A drive assist user interface module can be operatively connected to the at least one drive wheel. The drive assist user interface module can be configured to permit an operator of the system to selectively control movement of the at least one drive wheel. The drive assist user interface module can be part of or be attached to an attachment that includes a plate having a top surface. In one configuration, the top surface of the plate can be configured to extend parallel with a top surface of the platform when the attachment is attached to the platform.

A coupling mechanism is provided for coupling a supporting element to a frame, and includes a base member and a C-shaped retainer. The frame includes a frame body and a leg member that has a leg body extending downwardly from the frame body to terminate at an enlarged leg end. The base member defines therein a recess for the enlarged leg end therein. The supporting element is coupled to a lower major surface of the base wall. The C-shaped retainer extends to be disposed about the leg body, and is configured to be detachably coupled to a surrounding wall of the base member for retaining the enlarged leg end in the recess.

Embodiments of the present application disclose a universal wheel assembly and a smart cleaning device having the same. The universal wheel assembly includes a rotating shaft support and a universal wheel support. The rotating shaft support is configured to be fixed to a predetermined mounting position. The universal wheel support is connected to the rotating shaft support and is rotatable relative to the rotating shaft support. The universal wheel support is provided with a through hole, and the through hole is used for a mounting tool to pass through to fix the rotating shaft support to the predetermined mounting position.

A movable lifting device has a lifting and fixing device (10) and a moving device (20). One end of the lifting and fixing device is connected to the moving device, and the other end thereof is connected to a cargo to be shifted (30). The free rotation of the lifting and fixing device converts rotary motion into linear motion for lifting the cargo to-be-shifted. The movable lifting device has a simple and flexible structure, is easy to operate, and combines the functions of shifting and lifting. It can be operated anytime and anywhere, and is suitable for a wide range of applications. The movable lifting device reduces labor intensity, saves manpower and material resources, is cheaper to build, and easy to operate.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A roller has a wheel, a wheel axle and a pin which protrudes upward from a housing of the roller. A sleeve sits on the pin and is spaced apart from the pin radially and axially upward by a damping material arranged between the sleeve and the pin, the damping material being arranged so that all axial and/or radial contact between the pin and the sleeve is prevented. Alternatively, an attachment damping part can be arranged on a pin of the roller in overlap with the pin, wherein the attachment damping part has an inner sleeve and an outer sleeve, the inner sleeve being spaced apart radially and axially upward by a damping material arranged between the inner sleeve and the outer sleeve. The damping material is arranged in such a way that all axial and/or radial contact between the inner sleeve and the outer sleeve is prevented.

In one configuration, the top surface of the plate can be configured to extend parallel with a top surface of the platform when the attachment is attached to the platform.

A rough terrain cart for a wheel chair includes a frame operable to support a wheel chair and a wheel chair user. A pair of cart drive wheels are rotationally mounted to the frame. A locking mechanism is engaged with the frame. The locking mechanism is operable to secure the wheel chair to the cart. A rotational mechanism is engaged with the frame. The rotational mechanism is configured to support a pair of wheel chair drive wheels of the wheel chair and is operable to enable the wheel chair drive wheels to rotate when the wheel chair is secured to the cart by the locking mechanism. A transmission system is engaged with the frame. The transmission system is connectable to the wheel chair drive wheels. The transmission system is operable to transmit torque from the wheel chair drive wheels to the cart drive wheels.

A caster device includes a caster wheel configured to rotate around a horizontal rotation axis; and a case configured to expose a lower surface of the caster wheel, cover the caster wheel and have an inclined surface from a top of the horizontal rotation axis toward a bottom of the horizontal rotation axis.
