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.
Claims7
Multi-directional ball caster-type device (1), characterized in that it comprises:
- a housing (1a);
- at least one lower ring of rolling balls (1.2);
- at least one upper ring of rolling balls (1.3);
- and
- a main rolling ball (1.1), said main rolling ball (1.1), the at least one lower ring of rolling balls (1.2), and the at least one upper ring of rolling balls (1.3) being enclosed by the housing, wherein the at least one lower ring of rolling balls (1.2), and the at least one upper ring of rolling balls (1.3) are spaced from each other by 50° or less, allowing an inclination angle of the housing of 62° or less.
Multi-directional ball caster-type device (1), according to at least one of the preceding claims, characterized in that it is possible to have a slope of the device (1) at an angle of 60°, or less, and preferably 50°, or less.
