Abstract

The present invention consists of a novel ball making it possible to play outdoors and indoors. In order to facilitate the description of the shape of the ball, although it is manufactured in a single piece by moulding and not by the assembly of several parts, we are able to describe it in detail and to state that it is characterised by two truncated cones a and a1 adhering via their base to the two sides of a wheel b whose periphery is a bead which looks like a tyre c having a plane surface outside the latter; it also has two grooves g and g1, one on each side of the ball. A particular feature of the ball is that it converts its horizontal position when thrown into a vertical position on catching and vice versa, the movement being caused by the shape of the ball and not being the product of the thrower's initiative.

Description

La présente invention concerne les articles de sport et de loisir, une balle nouvelle pemettant le feu en plein aix et en salle et la pratique d'un sport nouveau qui lui est propre : "le DEXTRY" (nom de la balle et nom du sport). Une balle qui, de par sa nouveauté et son originalité, présente tous les avantages du loisin et du sport modernes. The present invention relates to sporting and leisure articles, a new ball allowing fire in the open air and indoors and the practice of a new sport of its own: "DEXTRY" (name of the ball and name of the sport ). A ball which, by its novelty and originality, has all the advantages of modern leisure and sport.

Cette balle peut être pleine ou creuse ; fabriquée en un seul tenant, elle n'est pas le résultat d'un assemblage. Son mode de fabrication est le moulage. This ball can be full or hollow; made in one piece, it is not the result of an assembly. Its manufacturing method is molding.

La description de l'invention et les dessins mettant en évidence la for -me de celle-ci sont donnés à titre indicatif et non limittatif. The description of the invention and the drawings showing the form thereof are given for information and are not limiting.

En serélérant F/6. 1 et pour laciliter la description de la forme exacte de la balle, bien que comme nous l'avons précisé un peu plus haut elle soit fasniquée d'un seul terant par moulage et non par assenblage de plusieurs parties, nous pouvons la détailler et dire que cet e balle se ra -mène à la forme de deux cônes tronqués (a et al) qui adhàreraient par leur base aux deux côtés d'une roue (b) dont le pourtour est un bourrelet à l'ima -ge d'un pneu (c) présentant une surface plane à l'extérieur de celui-ci- (d). By serélérering F / 6. 1 and to facilitate the description of the exact shape of the ball, although as we specified a little above it is made in a single terant by molding and not by assembling several parts, we can detail it and say that this e ball is brought back in the form of two truncated cones (a et al) which would adhere by their base to the two sides of a wheel (b) whose periphery is a bead in the image of a tire (c) having a flat surface on the outside thereof (d).

Cette balle pouvant être creuse, ses paxois sont d6signées F/6. 2 et 3 par (i et il) et (j et jl) et (m et ml) et (d); elle présente aussi deux canne -rures (g et gl), une de chaque côté de la balle.This ball can be hollow, its paxois are designated F / 6. 2 and 3 by (i and it) and (j and jl) and (m and ml) and (d); it also has two rods (g and gl), one on each side of the ball.

En se référant F16. 2 et 1, les deux cannelures (b et gl), situées de part et d'autre de la balle, sont tnès étroites, peu profondes, aux bords évasés et constantes, situées à la base des deux troncs de cônes (a et al) et laissant entre elles une épaisseur constante (h) d'environ la moitié de l'épais -seur centrale et saximale de la balle (e). Referring to F16. 2 and 1, the two grooves (b and gl), located on either side of the ball, are very narrow, shallow, with flared and constant edges, located at the base of the two trunks of cones (a et al ) and leaving between them a constant thickness (h) of about half of the central and saximal thickness of the bale (e).

En se référant F/6. 2 et 3 et 1, cette balle présente, de part et d'autre, une section plane (i et il) dont le diamètre est le cinquième du diomètre total de la balle (L), et qui correspond à l'épaisseur du bourrelet (f) dont la lar -geur (k) est le huitième du diomètre total de la balle (L) ; ces deux sections planes délimitent l'épaisseur centrale et marimale de la balle. Referring to F / 6. 2 and 3 and 1, this ball has, on both sides, a flat section (i and it) whose diameter is one fifth of the total diameter of the ball (L), and which corresponds to the thickness of the bead (f) whose width (k) is one-eighth of the total diameter of the ball (L); these two flat sections delimit the central and marital thickness of the ball.

Cette balle peut être fabriquée en mousses, en caoutchouc, en cuir, et dans toute matière pouvant faire l'objet d'un moulage thermocomorimé ou roto -moulage par injection. This ball can be made of foam, rubber, leather, and any other material that can be thermocomorimated or rotational molding by injection molding.

Aprés le lancement de la balle dans l'air, elle a pour spécificité de convertin ensuite sa position hori@ontale au lancement en une position verti -cale à la réception et vice versa ; ce mouvement est essentiellement provo -qué par la forme et la légèreté de la balle et ne relève pas de l'initiative du lanceur. After launching the ball into the air, it has the specificity of converting its horizontal position at launch to a vertical position at reception and vice versa; this movement is mainly caused by the shape and lightness of the ball and is not the initiative of the pitcher.

La légèreté de la balle importe effectivement pour son bon fonctionnement mais son poids peut varier suivant la force de lancer des joueurs, dans le do -maine sportif notamment. En effet, à la balle connespond un sport avec une fon -me de terrain propre et rapportée par la F/6. 4 où deux équipes de trois joueu -rs peuvent se livrer à une compétition suivant des règles déterminées. The lightness of the ball does indeed matter for its proper functioning, but its weight can vary depending on the strength of the throwing of the players, in the sports field in particular. Indeed, to the ball connespond a sport with a clean ground fun and reported by the F / 6. 4 where two teams of three players can participate in a competition according to determined rules.

Claims

11 A new ball allowing outdoor and indoor play characterized in that it can be full or hollow and the exact shape of which, although it is made in one piece by molding and not by an assem -wiring of several parts, boils down to that of two truncated cones (a and al) which would form by their base at the two sides of a wheel (b) whose periphery is a bead like a tire (c ) having a flat surface outside of it (d); this ball can be hollow, its walls are designated F / 6. 2 and 3 by (i and it) and (j and jl) and (m and m /) and (d); it has two piping lines (g and g /), one on each side of the ball.

2) Ball according to claim / characterized in that the two cones -lures (g and gl) on either side of the ball are very narrow, not very deep, with flared and constant edges, located at the base of the two trunks of cones (a et al), leaving between them a constant thickness (h) slightly less than that of the bead (f) and about half of the central and maximum thickness of the ball (e ).

3) A ball according to claim 1 characterized in that it presents, on both sides, a flat section (i and it) whose diometer is the cin-diene of the total diometer of the ball (L) and which corresponds the thickness of the bead (f) whose width (k) is one-eighth of the total diameter of the ball (L); these two planar sections delimit the central and ma -ximale thickness of the ball (e).

4) Ball according to claim / characterized in that after its launch -ment in the air it has the specificity of converting its horifontale position or launch into a vertical position on reception and vice versa; this movement being mainly caused by the shape and lightness of the ball and not falling under the initiative of the launcher.
