Definitions
- the invention relates to an inflatable ball for ball games, in particular football, comprising an outer ball having interconnected parts consisting of twelve equilateral pentagons and twenty equiangular hexagons, each pentagon being enclosed by five hexagons and, at the location of the connection between a pentagon and a hexagon, the sides connected to one another being of equal length.
- the hexagons are equilateral. It has been found that, in the inflated state, the stress in the material of the hexagons is markedly greater than the stress in the material of the pentagons. If the ball is kicked, the path through which the ball travels, the speed of the ball and the so-called spin will depend on the spot where the ball is struck. The behaviour of the ball when it bounces is also dependent on whether the ball strikes the ground with a hexagon or a pentagon. It will be obvious that such uncertainty is undesirable, in particular with top sportsmen.
- the object of the invention is to avoid the abovementioned disadvantages and to provide an inflatable ball as indicated in the preamble, whose hexagons and pentagons - in the inflated state of the ball - are subjected to essentially equal material stresses and degrees of stretch and whose spherical shape is improved.
- the ball is characterised in that each of the hexagons has three sides of relatively great length connected to a pentagon and three sides of relatively small length connected to a hexagon, and the length of the short sides is at least 0.69 times the length of the long sides.
- the length of the short sides of each hexagon will have to be 0.839 times the length of the long sides.
- the ball according to the invention does not necessarily have to comprise an inner ball, and if the ball according to the invention does have an inner ball, said inner ball will usually be glued to the outer ball consisting of pentagons and hexagons.
- Figure 1 shows a perspective view - not to scale - of a part of the ball according to the invention.
- Figures 2 and 3 show a view of a hexagonal part and a pentagonal part, respectively, used in the ball according to the invention.
- the ball according to the invention is composed of twelve equilateral pentagonal parts 1 and twenty hexagonal parts 2, each pentagon being connected to five hexagons and each hexagon being connected to three other hexagons and three pentagons.
- the hexagons are equiangular, but not equilateral, the ratio between the length of the relatively short cathetuses b and the length of the relatively long cathetuses a being at least 0.69 and preferably 0.839•
- the length of the long cathetuses a corresponds to the length of a side of a pentagon. It has been established that by choosing 0.69 a ⁇ b ⁇ a, the difference in material stress and material stretch in the pentagons and hexagons of an inflated ball is smaller than when b is smaller than O.69 a or greater than a.
