Abstract: 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.

Abstract: A driving device for a carriage includes a motor, a speed reducer, and a first mecanum wheel and a second mecanum wheel. The speed reducer decelerates the rotation input from the motor and outputs decelerated rotation. The first and second mecanum wheels are arranged in the axial direction parallel to the rotation axis of the decelerated rotation output from the speed reducer and are rotated by the decelerated rotation output from the speed reducer. In the axial direction, the center of the speed reducer is positioned between an outer end of the first mecanum wheel opposite to the second mecanum wheel and an outer end of the second mecanum wheel opposite to the first mecanum wheel.

Abstract: The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having an increased slope, which means a smaller angular slope level, or a more acute inclination angle between the central vertical axis of the device and the surface upon which it rolls. The slope, or inclination angle of the present improved device is from 62° to 50°, or less. As the inclinations angle can be more acute, the object supported on the rolling system, e.g. a luggage case, can be more sloped without having friction between the main ball involving structure and the ground.
