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.

Abstract: The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having a better contact angle between the ball and the ground. The contact angle of the present improved device is from 62° to 50°, or less. As the contact angle can be smaller, the object supported on the rolling system can be more sloped, for example, a luggage case, without having friction between the main ball involving structure and the ground.
