Definitions

  • Ball cases of this known type are know from DE 37 26 830 C1 and EP 0 773 045 B1, for instance.
  • the seams are in many respects the weak points of the ball case which usually is made from leather, artificial leather, plastic laminates or textile composite materials:
  • Each seam represents a deviation from the ideal spherical shape, i.e. causes an impairment of the roundness of the ball surface, which on the one hand results in an anisotropic wear behavior (the wear rate in the region of the seams is higher than in regions which are further away from the seams).
  • the seams of a ball have an effect on the spin of a “kicked” ball during free flight, comparable with the dimples of a golf ball which likewise have an effect on the flight behavior thereof.
  • the invention is based on the object to provide a ball case which is suited for lowering the number of the panels to less than 13 and thus reduce the overall seam length, and with which one can concomitantly manage to approach the ideal spherical shape and improve the flight behavior and the wear resistance of the ball or ball case.
  • the second group of polygons consists of polygons which are integrally formed from partial areas of one equilateral triangle and of three equilateral pentagons in such a manner that the pentagonal areas are situated at the points of the corners of the triangle and an imaginary corner and/or the centre of each of the pentagons lies on the perpendicular bisector of the opposite side of the triangle, which polygons are configured as separate, two-dimensional blanks.
  • the ball case consists of 8, 6 or only 5 two-dimensional blanks, namely 4 identical polygons of the second group in each case, and 4 or 2 identical one-piece blanks, most preferably, however, only one single one-piece blank, the blank(s) being composed of three-armed star-shaped areas.
  • the most advantageous embodiment of the ball case according to the invention is the “5 panel ball case” according to claim 5 , which consists of 4 identical polygons of the second group and one single one-piece blank which is composed of 16 three-armed star-shaped areas.
  • the one-piece blank which is composed of 16 three-armed star-shaped areas, has 6 terminal edges which are sewn, bonded or welded with each other in pairs such that the envelope of the blank (in the state connected with itself) is a sphere or has a three-dimensional shape which approaches the spherical shape as good as possible.
  • terminal edges which are sewn, bonded or welded with each other in pairs, preferably have a right-angled contour, with the associated corners being not rounded so that the contours of the three-armed star-shaped areas, adjoining by connecting these edges, will have a continuous extension.
  • the corners of the equilateral pentagons and the corners, complementarily assigned thereto, of the three-armed star-shaped areas are rounded, because this will facilitate the connecting of the edges; such rounding, however, is not compulsory.
  • All two-dimensional blanks (panels) can be punched-out leather or artificial leather pieces; it is preferred, however, that they are cut-outs punched out from a multi-layered laminate or composite material which may include 4 layers or sheets permanently fixed to each other, in fact advantageously
  • the waterproof plastic coating layer may be a film of polyolefin or polyurethane, and also the first foamed plastic layer preferably consists of at least one thermoplastic polyolefin or polyurethane. It would also be possible that the waterproof plastic coating layer and the first foamed plastic layer are jointly introduced in the composite in the form of an integral foam film.
  • the second foamed plastic layer preferably consists of at least one elastomer which may be an elastomer on the basis of natural rubber or isoprene or silicone; such elastomer may also be a thermoplastic elastomer or thermoplast-elastomer-copolymerisate.
  • the ball case according to the invention is preferably used as ball case for soccer balls; it may also be used for other sport and game balls, however.
  • FIG. 1 shows in a planar development a top view of 5 individual blanks or panels which, when they are connected with each other at their edges, form a spherical or almost spherical ball case according to the invention for use in a soccer ball;
  • FIG. 2 is an enlarged top view of a one-piece two-dimensional blank in the form of a polygon P 2 of FIG. 1 .
  • the ball case according to the invention consists of 5 two-dimensional blanks or panels which have been punched out from a suitable composite material.
  • the 5 panels pertain to two different groups of polygons, of which the first group of polygons generally is referenced by P 1 and consists of three-armed star-shaped areas 11 , 12 .
  • the first group of polygons generally is referenced by P 1 and consists of three-armed star-shaped areas 11 , 12 .
  • 16 three-armed star-shaped areas 11 , 12 contiguously form one single two-dimensional blank 10 made in one piece and having 6 terminal edges 4 , 5 , 6 , 7 , 8 , 9 which have a right-angled contour and the associated corners of which, contrary to all other corners of the polygon blank 10 , are not rounded.
  • edges 4 to 9 are sewn or bonded with each other in pairs, i.e. edge 4 with edge 7 , edge 6 with edge 8 and edge 5 with edge 9 . If edges 4 to 9 are sewn or bonded with each other in pairs in the aforementioned fashion, then all three-armed star-shaped areas 11 , 12 will be convexly curved in such a manner that the envelope of all three-armed star-shaped areas 11 , 12 and, with this, of the one-piece blank 10 is a sphere or virtually spherically shaped.
  • the one-piece blank 10 thus defines a skeleton of a spherical surface with 4 through-holes which will be closed by sewing on or sticking in a second group of polygons P 2 .
  • the polygons P 2 are integrally formed from partial areas of one equilateral triangle 20 ( FIG. 2 ) and of three equilateral pentagons 21 in such a manner that the pentagonal areas are situated at the points of the (imaginary) corners of the triangle and an imaginary corner E and/or the centre M of each of the pentagons 21 lies on the perpendicular bisector 22 of the opposite side of the triangle.
  • the polygons P 2 of the second group of polygons are likewise shaped as separate, two-dimensional blanks as the polygon(s) of the first group P 1 , the polygon(s) being realized in the drawn embodiment by the single one-piece blank 10 .
  • the corners of the equilateral pentagons 21 are rounded, just as the corners, complementarily assigned thereto, of the three-armed star-shaped areas 11 , 12 .
  • the one-piece and two-dimensional blank 10 formed from the three-armed star-shaped areas 11 , 12 can be cut into 2 or 4 congruent parts which, however, will have to be connected with each other again for manufacturing the ball case according to the invention, in fact along the cutting lines 1 , 2 and/or 3 .
  • the one-piece blank 10 is severed along cutting line 1 , one obtains 2 two-dimensional blanks (A+B) and (C+D) which can be brought to congruence by rotating one of the two sections, i.e. they are congruent.
  • a lower energy dissipation during kicking off a ball means that the amount of kinetic energy available for the free flight of the ball is larger, and that the spin which has been given to the ball during kicking off remains unchanged for a longer period. The latter, in turn, enhances the unerringness of a kicked-off ball and reduces the risk of any unwanted drifting of a kicked-off ball.
  • the particular geometry of the two different groups of polygons allows the use of sewing machines for a portion of the overall seam length to be sewn which is larger than was the case with the conventional ball case with 13 or even 32 panels, with the rounding of the corners of the panels particularly complying with the use of sewing machines.
