Abstract

A ball structure (1) is disclosed which comprises three panels (2, 3, 4) of identical shape which can be joined to form a spherical ball. The panels (2, 3, 4) can be cut from a template and their shape is adapted to minimize wastage of a substrate material cut according to a pattern provided by the template.

Claims

1. A ball comprising three substantially identically shaped panels joined together to form a substantially spherical surface, wherein each said panel, if laid flat prior to joining, is substantially rectangular in shape and comprises a pair of substantially straight and substantially parallel elongate edges, two diagonally opposed curved corner sections, and two diagonally opposed obtuse corner sections.

2. A ball as claimed in claim 1, wherein said panels are joined such that corresponding first obtuse corner sections of each said panel contact each other at a first point, and that corresponding second obtuse corner sections of each said panel contact each other at a second point diametrically opposed to said first point, said points representing poles of said ball.

3. A ball as claimed in claim 1, wherein said panels are differently colored in a predetermined hue sequence adapted to provide a pulsating visual effect when the ball is spun.

4. A ball as claimed in claim 1, wherein each said obtuse corner section comprises an intersection between two straight edges extending from adjacent curved corner section and elongate edges.

5. A ball as claimed in claim 1, wherein each said obtuse corner section comprises an intersection between a straight edge extending from an adjacent curved corner section and a curved edge extending from an adjacent elongate edge.
