Abstract
Abstract The present invention relates to an elastomeric support surface having a network of sculptures. According to the invention, the support surface is formed with a transverse network of narrow channels (2) having periodical widened portions (3) in each channel, a tong (4) of a width less than the width of the walls defining the channel and of a height equal to the depth of the channel being provided axially in each widened portion (3). Such a support surface is notably designed for forming the treading surface of so-called marine shoes in order to drain-off the water which can accumulate inside the sculptures.

An elastomeric support surface with a network of sculptures formed in known manner by a transverse network of narrow channels leaving therebetween protruding ribs the free edges of which form the bearing surface, wherein the network of channels is formed with periodical widened portions of each channel, a tong, having a width less than the width of the walls defining the channel and a height equal to the depth of the channel, being provided axially in each widened portion.
Claim 2
Dependent Claim
79 words
An elastomeric support surface with a network of sculptures formed in known manner by a transverse network of narrow channels leaving therebetween protruding ribs the free edges of which form the bearing surface, wherein the network of channels is formed with periodical widened portions of each channel, a tong, having a width less than the width of the walls defining the channel and a height equal to the depth of the channel, being provided axially in each widened portion.
Claim 3
Dependent Claim
28 words
