Abstract

A spacemesh structure for shoe making includes an upper mesh-texture layer, a lower mesh-texture layer and a reinforced structure in between. The reinforced structure comprises a plurality of supporting lumps arranged as a two dimensional array with gaps between two supporting lumps. A plurality of girders are disposed in the gaps in one direction leaving some gaps between every two adjacent lumps located between two adjacent girders.

Claims

1. A spacemesh structure for shoemaking comprising:

an upper mesh-texture layer,

a lower mesh-texture layer; and

a reinforced intermediate layer between said upper and lower mesh-texture layers,

said reinforced intermediate layer comprising;

a plurality of supporting lumps arranged as a two-dimensional array with gaps between every two adjacent supporting lumps, said gaps forming a plurality of streets in two orthogonal directions; and

a plurality of elongated supporting girders filling streets in one direction and leaving a plurality of gaps between adjacent supporting lumps disposed between two adjacent elongated supporting girders.

2. The spacermesh structure for shoemaking as claimed in claim 1, wherein said elongated supporting girders are ropes, flexible bands, foam plastic strips, plastic strips, spring coils or metallic bars.
