Definitions

  • the invention relates to a bowling ball, in particular for petanque, the Provencal game, the long and the lyonnaise, such ball being of the type having a spherical surface comprising, on the one hand, a large circle forming a meridian of departure having two diametrically opposite points forming two poles and, secondly, equidistant from these two poles, an equatorial circle delimiting two hemispheres, said spherical surface further comprising at least one pattern consisting of a groove having a first end, located on said meridian of departure and on a first parallel of said spherical surface adjacent the pole of a first hemisphere, and a second end.
  • the invention aims to provide a ball that offers the advantage of being even more technical than all the balls currently used, including by professional players, in that the person who will launch, pointer or shooter, may give said ball according to the invention an effect of a magnitude never reached so far.
  • such a ball is characterized in that said groove has, starting from said first end, an S-shape similar to a sinusoidal shape and comprises two sections, of opposite curvatures, connected to one another.
  • an inflection point located on an inflection meridian, at least a portion of a first stretch from said first end being located on said first hemisphere between the starting meridian and the inflection meridian and having a first curvature of which the concavity is turned towards said inflection meridian
  • at least a portion of the second section is situated on the side opposite to that where said part of the first section is located in relation to meridian inflexion audit and extends to said second end of the groove, which second end is located on a parallel of said spherical surface adjacent the pole of the second hemisphere, said portion of the second section having a curvature whose concavity is turned towards said inflection meridian.
  • the concavity of the first curvature of said portion of the first section may also be turned towards said starting meridian. But also, said concavity can be only turned towards said inflection meridian.
  • said second end of the groove may also be located on said starting meridian. But also, said second end of the groove may be located on a meridian other than said starting meridian.
  • said inflection point may be located on said equatorial circle. But also, said inflection point may be located between said equatorial circle and one of said parallels.
  • all of said first section starts from said first end, can be located on said first hemisphere, between the starting meridian and the inflection meridian, and has said first curvature.
  • all of said second section may be located on said opposite side with respect to said inflection meridian and extend to said second end of the groove and have said second curvature.
  • said starting meridian and said inflection meridian may be one and the same meridian.
  • the second end of the first section of the groove may be located on said first meridian. But also, the second end of the first section of the groove may be located on a different meridian and neighbor of the first meridian.
  • the angle made by the planes respectively containing the starting meridian and the inflection meridian and the axis joining the two poles may be between 0 ° and 30 °.
  • the concavity of the curvature of the first section can be directed in projection on the equatorial circle in the clockwise direction.
  • the concavity of the curvature of the first section can be directed in projection on the equatorial circle in the anti-clockwise direction.
  • the ball according to the invention can thus be used by both left-handed and right-handed players.
  • said pattern may consist of multiple grooves. It is of course essentially with these multiple designs that the ball according to the invention, with consequent multiple forms, will be marketed.
  • first ends of the first sections of at least two grooves may be located at points different from the said parallel of the first hemisphere and the second ends of the second sections of the said grooves may be located at points different from the said second parallel. hemisphere.
  • the multiple grooves can be divided into at least two assemblies, the first ends of the first sections and the second ends of the second sections of the grooves of two sets being located, respectively, on different parallel neighbors of the first pole. and on different parallel neighbors of the second pole.
  • the number n of the multiple grooves can be between 3 and 40.
  • the groove or each groove may be discontinuous or interrupted.
  • the number of discontinuities, or interruptions can be between 2 and 10.
  • the interrupts of the two sets can be shifted to different parallels.
  • said interruptions may be formed of portions of the spherical surface, which spherical surface is smooth outside the groove or each groove.
  • the groove or each groove may have a section V or U.
  • the sphere may be hollow and the groove or each groove may be located on the outer spherical surface of said sphere.
  • the ratio of the area of said groove or the cumulative area of the grooves to the total area of said spherical surface may be between 5% and 30%.
  • the diameter of said sphere may be about 75 mm.
  • the depth of the groove or each groove may be between 0.10 mm and 0.20 mm and more preferably equal to 0.15 mm. More preferably, the width of the groove or each groove may be between 1 mm and 1.5 mm.
  • Each of the balls A and B of FIGS. 1a, 1b and 2a, 2b is formed by a hollow sphere having an outer spherical surface 1 comprising, on the one hand, a large circle forming a first meridian 2 which has two diametrically opposite points forming two Poles North 3 and South 4, and, secondly, equidistant from these two poles 3 and 4, an equatorial circle 5 delimiting two hemispheres North 6 and South 7.
  • the spherical surface 1 comprises at least one pattern constituted by a groove 8 formed on the spherical surface of the ball, this groove having a first end 8a 'located on the meridian 2 and on a parallel 9' of the spherical surface 1 adjacent the pole 3 of a first hemisphere 6, and a second end 8b 'located on another meridian, different from the meridian 2 , and on a parallel 9 "of the spherical surface 1 close to the pole 4 of the second hemisphere 7.
  • the groove 8 has, starting from the first end 8a ', an S shape similar to a sinusoidal shape.
  • first section 8 ' It comprises, on the first hemisphere 6, a first section 8 ', all of which extends from the first end 8a' to the second end 8b "which is located on the equatorial circle 5.
  • the entire first section 8 ' has a first curvature whose concavity C' is turned towards another meridian 10, different from the meridian 2, called the inflection meridian, and is situated on a first side with respect to this inflection meridian.
  • the groove 8 further comprises, on the second hemisphere 7, a second section 8 '' which is connected to the first section 8 'and extends from a first end 8a "situated on the equatorial circle 5, coinciding with the second end 8b "of the first section 8 ', to said second end 8b' of the groove which is located on the parallel 9" of the second hemisphere 7.
