Abstract

The roller skates have two spheres (2) mounted on a chassis (1), one at the front and one at the back. Only two points are in contact with the ground giving greater manoeuvrability. The spheres are made in synthetic material that can be varied according to the surface on which they are used. The spheres are mounted on parallel axles (3). They are striated (7) to prevent the skate sliding sideways and the striations are pref. parallel to the longitudinal axis (X-X) of the skate. They can be regularly or irregularly spaced apart.

Description

La présente invention se rapporte à un patin d'un type nouveau permettant d'évoluer sur le sol d'une manière comparable à celle d'un patin à glace. Sa mania bilité permet d'effectuer toutes les figures possibles de patin à glace ainsi que des figures de danse. The present invention relates to a skate of a new type making it possible to evolve on the ground in a manner comparable to that of an ice skate. Its maneuverability allows you to perform all possible ice skating figures as well as dance figures.

Conformément à l'invention, le patin comprend deux sphères montées sur un chassis, une sphère avant et une sphère arrière, de sorte que seuls deux points sont en contact avec le sol ce qui donne au patin une possi bilité d'évolution excellente. According to the invention, the skate comprises two spheres mounted on a frame, a front sphere and a rear sphere, so that only two points are in contact with the ground which gives the skate an excellent possibility of evolution.

Suivant une forme de réalisation, les sphères sont montées sur des axes parallèles supportés par des étriers du châssis. According to one embodiment, the spheres are mounted on parallel axes supported by stirrups of the chassis.

Suivant une variante, les sphères sont striées de manière à pouvoir offrir une résistance au glissement latéral possible du patin. According to a variant, the spheres are striated so as to be able to offer resistance to possible lateral sliding of the skate.

Le châssis du patin reçoit une chaussure du type "basket1, ou du type cuir laquelle est vissée sur le châssis ou fixée par tout autre moyen tel que des courroies. The frame of the skate receives a shoe of the "basket1" type, or of the leather type which is screwed to the frame or fixed by any other means such as belts.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui va suivre faite en regard du dessin annexé sur lequel
- la figure 1 est une vue en élévation latérale d'un patin conforme à l'invention ;
- la figure 2 est une vue en plan du dessous de ce patin conforme à l'invention
- la figure 3 représente en bout et en coupe partielle ce même patin selon l'invention.
Other characteristics and advantages of the present invention will emerge from the description which follows, given with reference to the appended drawing in which
- Figure 1 is a side elevational view of a shoe according to the invention;
- Figure 2 is a bottom plan view of this skate according to the invention
- Figure 3 shows at the end and in partial section this same shoe according to the invention.

Dans la forme de réalisation représentée, un patin selon l'invention comprend un châssis (1), de préférence métallique, en particulier en t'duralumin", et deux sphères (2) montées en rotation sur deux axes (3) parallèles entre eux et supportés par des étriers (1A) du châssis. In the embodiment shown, a shoe according to the invention comprises a chassis (1), preferably metallic, in particular made of t'duralumin ", and two spheres (2) mounted in rotation on two axes (3) parallel to each other and supported by stirrups (1A) of the chassis.

La partie plane (4) supérieure du châssis reçoit une chaussure (5) qui peut être vissée sur le châssis et être ainsi entièrement solidaire du patin. La fixation de cette chaussure d'un type "basket" ou d'un type cuir peut également se faire par tout autre moyen approprié, en particulier par des courroies (non représentées). The upper flat part (4) of the chassis receives a shoe (5) which can be screwed onto the chassis and thus be entirely secured to the skate. The attachment of this shoe of a "basketball" type or of a leather type can also be done by any other appropriate means, in particular by straps (not shown).

Le patin peut être équipé d'un. système de freinage classique à plot (6). The skate can be equipped with a. conventional stud braking system (6).

I1 ressort de cette conception nouvelle de patin que seuls deux points (A) et (B) sont en contact avec le sol ce qui limite le frottement et permet une grande maniabilité dans l'évolution. C'est ainsi, par exemple, qu'une rotation sur place peut être effectuée, soit sur la sphère avant, soit sur la sphère arrière, pour obtenir un changement de direction instantané. I1 emerges from this new skate design that only two points (A) and (B) are in contact with the ground, which limits friction and allows great maneuverability in evolution. Thus, for example, a rotation on the spot can be carried out, either on the front sphere, or on the rear sphere, to obtain an instantaneous change of direction.

Le basculement du corps fait bien entendu changer le point d'application de chaque sphère sur le sol comme le montre la figure 3 mais, de toute manière, quelle que soit la position sur la sphère de cette application, celle-ci se résume toujours à un point. The tilting of the body of course changes the point of application of each sphere on the ground as shown in Figure 3 but, anyway, whatever the position on the sphere of this application, it always comes down to a point.

Pour contrarier le glissement latéral du patin qui peut avoir lieu, en particulier dans ce cas de basculement, les sphères peuvent être striées, comme représenté sur les figures 2 et 3; ces stries (7) sont de préférence parallèles à l'axe longitudinal (X-X) du patin. Les stries parallèles (7) peuvent être d'un écart constant entre elles ou.non et peuvent être limitées à un ou plusieurs segments sphériques. To counter the lateral sliding of the pad which can take place, in particular in this case of tilting, the spheres can be striated, as shown in FIGS. 2 and 3; these ridges (7) are preferably parallel to the longitudinal axis (X-X) of the pad. The parallel streaks (7) can be of a constant distance between them or not and can be limited to one or more spherical segments.

Le matériau composant les sphères (2) peut être différent suivant le revêtement du sol ou l'utilisation du patin et, suivant un exemple de réalisation, ce matériau est une matière synthétique moulée. The material making up the spheres (2) may be different depending on the floor covering or the use of the pad and, according to an exemplary embodiment, this material is a molded synthetic material.

Dans la forme de réalisation représentée, les sphères présentent des faces polaires planes ou méplats (8) du fait du montage sur roulements (9) de ces sphères avec rondelles (10) et écrous (11). In the embodiment shown, the spheres have flat or flat pole faces (8) due to the mounting on bearings (9) of these spheres with washers (10) and nuts (11).

D'une façon générale, l'invention apporte un progrès important dans l'évolution sur patin de sol en rendant son évolution comparable à celle d'un patin à glace. La maniabilité apportée par l'invention permet 11 exécution de toutes figures de patin à glace ou des figures de danse, l'une des possibilités d'évolution apportée par l'invention étant, par exemple, le virage en parallèle. In general, the invention provides significant progress in the evolution of a skate by making its evolution comparable to that of an ice skate. The maneuverability provided by the invention allows 11 execution of all ice skating figures or dance figures, one of the possibilities of evolution provided by the invention being, for example, the turn in parallel.

I1 est bien entendu, enfin, que la présente invention n'a été décrite et représentée qu'à titre d'exemple préférentiel et qu'on pourra apporter des équi- valences dans ses éléments constitutifs sans, pour autant sortir du cadre de l'invention. C'est ainsi, par exemple que le patin peut comporter plus de deux sphères de contact avec le sol.  Finally, it is clearly understood that the present invention has only been described and shown as a preferred example and that equivalences may be made in its constituent elements without, however, departing from the scope of the invention. Thus, for example, the skate can have more than two spheres of contact with the ground.
