Anti-slip device to be used for securing loaded goods, comprising several layers lifted or lowered for revealing holding structure

摘要

The anti-slip device is assembled of at least two layers, the upper layer (1) provided with several rows of holes (4), the lower layer (2) with spikes (5) protruding from its upper surface. For loading the spikes (5) are accommodated inside holes (4), creating a plane upper surface. When an air cushion is inflated the spikes (5) are put under pressure and are lifted above the surface of the upper layer (1), resulting in a slip-preventing structure.
