Abstract

The in-line skate has wheels (1 - 5) whose axles are mounted along a curve. The central wheel (3) is lowest, the wheels (2, 4) on either side are mounted on the same level and the end wheels (1, 5) are mounted on a third level.

Description

La présente invention a pour objet un patin à roulettes en ligne autorisant la rotation, pour permettre à tout sportif, même de haut niveau, de pratiquer sur toute surface plane des figures identiques à celles du patinage sur glace (Danse ou Patinage Artistique), ce que l'on ne peut réaliser avec un patin à roulettes en ligne traditionnel. The present invention relates to an inline roller skate allowing rotation, to allow any athlete, even at a high level, to practice on any flat surface figures identical to those of ice skating (Dance or Figure Skating), this that you can't do with a traditional inline skate.

La caractéristique essentielle du dispositif faisant l'objet de cette invention réside dans la courbure de la ligne de roulement qui s'apparente à la courbure d'un patin à glace. The essential characteristic of the device which is the subject of this invention resides in the curvature of the rolling line which is similar to the curvature of an ice skate.

Cette courbure permet une bascule du patin par le déplacement du poids du corps et du centre de gravité, diminuant de ce fait la surface d'appui au sol. Le patin ne prend alors appui que sur une, voire deux roues au maximum, atténuant ainsi la résistance et le frottement et autorisant la rotation. This curvature allows a tilting of the skate by the displacement of the weight of the body and the center of gravity, thereby decreasing the bearing surface on the ground. The skate then only rests on one, or even two wheels at most, thus reducing resistance and friction and allowing rotation.

Cette liberté de mouvement confère la possibilité d'effectuer des figures imposées de patinage telles que : Trois, Dehors, Dedans, Contre-rocking, Rocker, Cross-rolls, Bracket, Twizzle, etc.... This freedom of movement gives the possibility of performing compulsory figures of skating such as: Three, Outside, Inside, Counter-rocking, Rocker, Cross-rolls, Bracket, Twizzle, etc.

Les roues au nombre de cinq, toutes identiques mais pouvant être de diamètre différent de celui proposé (63 mm), sont fixées sur deux montants et disposées à égale distance les unes des autres dans le plan horizontal. The five wheels, all identical but possibly of different diameter from that proposed (63 mm), are fixed on two uprights and arranged at equal distance from each other in the horizontal plane.

La ligne d'axe de ces roues suit la courbure d'une lame de patin à glace. Le décalage des axes de roues s'effectue dans le plan vertical. Il peut varier en fonction de la taille et de l'élasticité des roues. Dans le prototype, il est défini comme suit :

- L'axe de la roue centrale 3 est le plus bas par rapport au sol, - L'axe des roues 2 et 4 est décalé de 1 mm à 4 mm vers le haut, et de préférence 2,5 mm. Ces deux roues sont sur le même plan horizontal. The center line of these wheels follows the curvature of an ice skate blade. The wheel axes are offset in the vertical plane. It can vary depending on the size and elasticity of the wheels. In the prototype, it is defined as follows:

- The axis of the central wheel 3 is the lowest with respect to the ground, - The axis of the wheels 2 and 4 is offset from 1 mm to 4 mm upwards, and preferably 2.5 mm. These two wheels are on the same horizontal plane.

- L'axe des roues 1 et 5 est décalé de 6 mm à 9 mm vers le haut, et de préférence 7,5 mm. Ces deux roues sont sur le même plan horizontal. - The axis of the wheels 1 and 5 is offset from 6 mm to 9 mm upwards, and preferably 7.5 mm. These two wheels are on the same horizontal plane.

Les roues 2,3 et 4 permettent la rotation, alors que les roues 1 et 5 stabilisent l'engin. Wheels 2, 3 and 4 allow rotation, while wheels 1 and 5 stabilize the machine.

Les dessins annexés permettent de mettre en évidence la courbure de la ligne de roulement par rapport à un plan horizontal : Figure 1 : vue d'ensemble du patin Figure 2 : diagramme de la courbure des axes de roues et de la ligne de roulement. The accompanying drawings show the curvature of the running line with respect to a horizontal plane: Figure 1: overview of the shoe Figure 2: diagram of the curvature of the wheel axles and the rolling line.
