Definitions

This invention relates to an inflatable ball (1) for footballing and recreational activities, and therefore hollow, that can be used in any area where balls are used: sports, culture and science.
This invention relates to an inflatable ball (1) for footballing and recreational activities. It is based on a new geometric model suitable for building spherical three-dimensional structures. Even though it has potential for use in areas such as the building industry, this invention has been developed with a view to producing inflatable balls for footballing and recreational purposes.
the geometry of the balls made from tanned leather and ox bladder, resembled that of the Earth. They consisted of panels stitched together. They were wider at the equator and narrowed towards the poles.
the first major improvement was a geometric adjustment to the shape. As the inflation system improved, with a rubber air chamber, it could keep its round shape for longer. This model to some extent resembled today's volleyball balls. It was basically composed of 18 faces or panels and was officially in use until 1966 when it was replaced by a ball of similar geometry, but better made, to comply with the strict requirements of FIFA to be considered the 'official ball'.
the football-making process is today divided into two, duly patented, aspects: materials, and geometry.
This invention relates to an inflatable ball (1) for footballing and recreational activities. It is based on a new geometric model. It considers the use of unrolled folding curved surfaces - cylindrical surfaces - to create spherical three-dimensional structures - domes and geoids - to replace the current structures that make use of plane geometrical figures such as the truncated icosahedron.
This invention is a ball (1) suitable for footballing and recreational activities, composed of 12 faces or panels (2), which are reflected on the surface of the ball (1), each corresponding to sections of cylindrical surfaces, that is, unrolled folding curved surfaces.
the ball (1) may thus be described as a geometric figure, a Non-polyhedron, composed of 12 faces or panels (2), 24 edges (3) and 14 vertices, six of type (A) and eight of type (B),
the advantage of adapting this geometric figure to a sphere is that, because it has fewer cylindrical faces or panels, and a smaller number of vertices (compared with the previous model - inflated truncated icosahedrons), there are fewer areas that have to be inflated, and it is easier to achieve the desired outcome: the ball (1).
the cumulative stress in the vertices can be distributed along the edges and thence it is transmitted equally to all the faces or panels.
the invention thus comprises of an inflatable ball for footballing and recreational activities composed of an inner air chamber and outer covering formed by 12 all equal quadrilateral faces or panels (2), with each panel (2) bounded by 4 edges (3) of equal length by which the panels are joined to one another. Each panel (2) is bounded on its circumference by four other panels (2).
the panels (2) are bounded by 4 edges (3) which, since they result from the intersection of three cylinders with orthonormal axes of equal diameter, correspond to sections of an ellipse, whose smaller axis is r (radius of the cylinder), 11 cm, and larger axis is r 2 , dimension between 15,55 cm and 15,56 cm, when converted to decimals, since the intersection between each pair of cylinders is 45°.
the panels (2) are doubly symmetrical plane geometric figures, both in relation to segment nr/2 (5), which corresponds to one quarter of the circumference of the base of the cylinder, and in relation to the segment r 2 (4) which corresponds to the portion of the generating line that passes through the mid-point of the previous segment, which intersects it also at its mid-point, and which corresponds to the maximum moment of this magnitude, equal to twice the cosine of 45°, angle at which each pair of cylinders intersects.
Each panel has four opposing vertices, two type (A), ends of the segment nr/2 (5), and two type (B), ends of the segment r 2 (4).
each panel (2) is between 160,70 cm 2 and 160,80 cm 2 , its perimeter is between 47,00 linear cm and 47,30 linear cm, making between 1928,40 cm 2 and 1929,60 cm 2 of material; and between 2256,00 cm and 2270,40 cm of outline necessary for joining according to the vertices of each end of the ellipse portion: (A) to (A) and (B) to (B).
the panels (2) thus correspond to the joining of four faces or panels on vertex (A), with tessellation [4,4,4,4], and the joining of three faces or panels on vertex (B), with tessellation [4,4,4], seeing tessellation as the splitting of the area into regions.
Each edge (3) is delimited at 45°, with the least pronounced curve prevailing, and it is supported on a vertex that corresponds to the ends of two orthogonal segments which intersect at the mid-point, where the first (4) measures r 2 , a dimension between 15,55 cm and 15,56 cm, and the second (5), given by the unrolling of the circumference portion, measures nr/2, a dimension between 17,27 cm and 17,28 cm, after the surface development of each panel.
Each edge (3) thus corresponds to a portion of an ellipse that is supported on two vertices, where the end of the ellipse portion corresponding to the point above the smaller axis is supported on the vertex (A) of the segment nr/2 (5), and the end of the ellipse sectioned by the planes at 45° corresponds to the vertex (B) of the segment r 2 (4).
Each edge (3) is between 11,80 cm and 11,85 cm long, and when joined two by two they yield a stitched area of 283,20 cm to 284,40 cm, which joins all the panels (2).
