Sports ground, in particular tennis court or mini court formed by using removable panels

Claim 1

An articulated modular athletic playing surface comprising: (a) a plurality of flexible closely aligned horizontal panels of rectangular configuration; (b) multiple plates of isolating material, each slightly smaller than its respective panel and having a lower surface bearing on the ground and an upper surface reslilently supporting the lower surface of its respective panel so as to maintain the proper height of the panels from the ground, give flexibility to the playing surface, and isolate the panels from the ground whereby differences in temperature and hygrometry between the lower and upper surfaces of the panels are reduced; and (c) a plurality of similar connecting element means, each having horizontal means and vertical means wherein some of the connecting means join the longitudinal edges of adjacent panels with the other connecting means joining the corners of adjacent panels, said some connecting means having the horizontal means fixed to the undersurfaces of the opposite longitudinal edges of two adjacent panels and said other connecting means having the horizontal means fixed to the undersurfaces of the corner of four adjacent panels, where the vertical means is of the same approximate height of said isolating plates so that the bottom of said vertical means bears on the ground.
