Definitions
- the invention relates to the field of playing balls, in particular balls courttanque or game of Lyonnaise. It relates more particularly to the balls made by assembling two hemispherical shells. It aims more precisely the geometry of the internal surface of these shells allowing a firstly, to improve the behavior of the ball during the game, and secondly, to facilitate its manufacture.
- Document FR-A-2 638 375 proposes as a solution to carry out at inside the ball a network of circular streaks intended to influence the propagation of the shock wave inside the ball.
- results obtained with such streaks are insufficient from a point of view of the behavior of the ball.
- realization of these streaks requires the complex machining operations to be carried out and which significantly increase the price cost of such a ball.
- connection of all the ribs between them facilitates the propagation of the shock wave on the internal surface of the ball and ensures no attenuation of it. It follows that the rebound phenomena are only very partially reduced.
- complex tools namely in particular a punch on which must be hollowed out the complementary network of the ribs sought on the final ball. The machining and more precisely the milling of these hollow areas is complex and therefore costly.
- the problem which the invention therefore proposes to solve is to allow the production of a ball whose structure ensures good attenuation of the propagation of the shock wave, which is easy to perform and does not require a complex tools.
- the invention therefore relates to a ball for a game of balls, in particular for the courttanque, made by assembling, at its equatorial plane of two hemispherical shells produced in particular by stamping and stamping, forming, foundry or machining, each shell comprising on its internal face protruding patterns.
- This ball is characterized in that the patterns consist of independent ribs arranged only on all or part of the meridians.
- the invention consists in individualizing the patterns arranged on the inside of the ball and arrange them in such a way that the tools allowing them to be obtained is easy to carry out.
- the invention consists in distributing on the inner face of the ball, independent outgrowth zones, inside which operates the attenuation of the shock wave, these protruding portions corresponding, to the tooling level, in hollow areas easily achievable by milling "in rolling".
- the different ribs can for example be continuous and then occupy the entire length of the meridians on which they are placed, excluding the pole area, to avoid any mechanical connection. They can also be discontinuous and made up of a plurality of segments occupying a fraction of the length of the meridians on which they are arranged.
- the ribs are of length different and distributed in an alternating and regular manner on the internal surface of each shell.
- the number of ribs is even to avoid the appearance of imbalances.
- the excess thickness of each rib is gradually decreasing at the end of each rib.
- each half-shell has on its outer face a means provided for this purpose.
- each rib typically is between 1.5 and 3 millimeters and the maximum allowance for each rib is between 1 and 3 mm. Indeed, below a millimeter, we see that the attenuation of the wave shock is not enough.
- the invention consists in making a ball, in particular for the courttanque game which has patterns on its inner surface allowing to mitigate the propagation of shock waves, and that is as easy as possible to achieve.
- This type of ball is obtained by the association of two shells hemispherical obtained by stamping-forging, by foundry or by machining. With regard to forging, one can proceed by cold deformation, hot or half hot.
- the inner face of such hemispherical shell (1) has a plurality of ribs (2, 3) distributed over the whole surface. According to an essential characteristic of the invention, these ribs (2, 3) are arranged along the meridians (M) of the shell (1).
- each of the ribs makes it possible to obtain attenuation characteristics of the specific shock wave.
- the ribs (2,3) are even in number, which allows to maintain symmetry by relation to the axis (OP) connecting the center of the ball to one of the poles, and therefore to limit the imbalances.
- each rib (2, 3) extends over a part of the meridian (M) which it occupies without discontinuity.
- the ribs (2, 3) break down into two groups, interspersed alternately.
- a first half of the ribs (3) have a length substantially equal to 80% of a half-meridian (M3) while the other half (2) occupies approximately 60% of the interposed meridians (M2).
- M3 half-meridian
- M2 interposed meridians
- the maximum excess thickness of a rib (2, 3) is included between 1 and 3 millimeters, preferably around 2.5 mm, while the width of the same rib (2, 3) is also between 1.5 and 3 millimeters.
- the invention is in no way limited to the mode of illustrated realization but on the contrary embraces all the variants of number of shapes and dimensions compatible with an essential principle of meridian distribution and the absence of connection of such ribs.
- connection area between the rib and the spherical surface interior forms an angle as pronounced as possible, close to 90 °.
- each of the ribs (22, 23) occupy only a portion of the meridian (M22, M23) on which they are located.
- these ribs (22, 23) are broken down into two groups arranged between different parallels (24, 25) drawn in dotted lines.
- a first group of about twenty short ribs (23) are made at level of proximity to the equatorial plane (E) while the second group includes a dozen longer ribs (22) converging toward the pole (P).
- the ribs of the two groups are present on four common meridians, which facilitates the operation of machining the punch.
- the profile and the thickness variation of the ribs (22, 23) must be compatible with good clearance of the punch (10), as observed for the end (26) the rib (23) of FIG. 4.
- the ribs interior can advantageously be arranged to correspond to the external distribution of the studs.
- each half-shell (20) may include an indexing lug (30) making it possible to compare the internal ribs (22, 23) during assembly of the two hemispherical shells (20).
- the geometry according to the invention allows not only to improve the performance of the ball, but also facilitates its manufacture.
- the punch (10) which makes it possible to create the ribs (22, 23) of Figure 3
- characteristics of the invention is obtained by relatively machining simple.
- the grooves (12, 13) of the punch (10) corresponding to the ribs (22, 23) of the inner face of the ball are produced by milling "in rolling "from a milling cutter pivoting about an axis perpendicular to its displacement.
- This strawberry moves along the meridians (M12, M13) and digs the grooves (12, 13) according to a profile allowing easy release of the half-shell.
- the extra thickness of the rib (2, 3) of the shell (1) or additionally the depth of the groove (12, 13) is variable at the level of the end (4, 5, 6, 7; 14, 15, 16, 17) thereof.
- the geometry obtained allows an improvement in the flow of the metal during stamping and stamping which results in a doubling the number of balls made from the same tool.
