Abstract

The invention relates to a device whose body (1) is intended to receive a spherical roller (2) moving under a cap (3) via a sheet of balls (4), characterized in that the cap ( 3) is profiled so that its thickness (7) at the base of the stud (8) for attachment to the body (1) is less than the thickness of its edge (9) forming the zone (5) in order to obtain a range (6) for spreading the balls (4) having a sufficiently small angle of inclination to prevent their pyramidal accumulation under the thrust exerted by the wheel (2) and to promote their spreading in a constant flow towards the zone (5) supply of roulette (2). The device according to the invention is intended for all objects that can be moved manually, towed, motorized, remote-controlled or robotic.

Description

TITLE: OMNIDIRECTIONAL SPHERICAL ROULETTE DEVICE

The present invention relates to a device making it possible to operate an omnidirectional spherical wheel by converting its motion into rational mechanical kinetics.

We know by the documents cited below the spherical wheel but we know that the documents for never having seen a single run (except perhaps the wheel Peugeot Citroen which seems of a different nature for others uses) whereas if that had been the case it will long ago have invaded our daily life.

Indeed, for a spherical roller to operate it is imperative that the cap portion opposite to the direction of rolling is constantly and sufficiently supplied with balls that none of the cited patents is able to claim all having a zone d expansion and spreading balls too vertical so that they pile up pyramid under the thrust generated by the rotation of the sphere and too slow to detach themselves they can not supply the sphere in good conditions .

OBJECT OF THE INVENTION The object of the invention is to provide by its technical and novel methods in kinetics a considerable progress in the known methods of moving objects, to make them easier to adapt, more precise, more stable, more aesthetic, more economical etc ... The invention uses separately known material and technical bodies which in combination with new design shapes and methods give it the requirement of novelty by its real inventive contribution.

DESCRIPTION OF THE INVENTION

Device according to the invention illustrated by the appended drawings:

Figure 1 shows a section of the device positioned under an object Figure 2 shows another section of the cap.

With reference to these drawings:

The device according to Fig.1-2 relates to a structure whose body (1) is intended to receive a spherical roller (2) omnidirectional displacements moving under a spherical cap (3) concave via a web of balls (4) circulating in anarchic trajectories under the impulse generated by the rotation of the wheel (2) via an expansion zone (5) to a spreading range (6) and concentration zone (5) opposite to the running direction for the supply of balls (4) of a new cycle.

The cap (3) according to the device is profiled so that its thickness (7) at the base of the stud (8) for attachment to the body (1) is less than the thickness of its edge (9) forming the zone d expansion (5) regardless of the form fig.2 to obtain a range (6) for spreading the balls (4) having a sufficiently small angle of inclination to prevent their pyramidal accumulation under the pressure exerted by the wheel (2) and promote their spreading in a constant flow on either side of the stud (8) to the zone (5) of concentration and supply of the wheel (2).

The device according to fig.1-2 may or may not comprise between the body (1) and the range (6) around the stud (8) a reducer / accelerator balls (4) - not shown consisting of a cylindrical ring d a diameter substantially equal to the dimension obtained between the external base of the stud (8) and the priming of the range (6) in the concentration zone (5) - moving according to the movements of the wheel (2) intended to reduce them quantitatively and accelerate the flow by channeling them on both sides of the pad (8).

The body (1) of the device according to Fig.1 will include at least one channel (15) for injecting detergents and drying the interior of the device.

The body (1) of the device according to fig.1 is designed to be associated and dissociated instantly without the aid of tools to / from the object (10) that will receive it, it has on the same side on the one hand a relief (11) intended to be positioned in a cavity (12) reserved under the object (10) and secondly a zone (13) magnetized or adhesive repositionable or not corresponding to a zone (14) receiving arranged under the object (10)

The device according to the invention may be arranged so that it can receive a so-called fixed wheel that is to say unidirectional while retaining for aesthetic reasons the appearance of the spherical wheel.

The device according to the invention may be motorized.

The device according to the invention may be equipped with brakes, bumpers, brushes, electrostatic skirt or any other system tending to make room for the passage of the wheel.

The components constituting the device may be made of any material, multi molded materials, overmoulded or machined.

This device is intended for all objects likely to be moved manually, motorized tows, remote control or robotic.
