Linear load e.g. rope, launching device for use in e.g. military field, has shock absorber unit constituted of elastic strap folded in accordion, where loops of accordion are transversally stitched together using stitches

摘要

The device has a shock absorber unit (4) constituted of an elastic strap (20) folded in accordion, where loops of the accordion are transversally stitched together using stitches (21). The stitches are tearable or destructible so that kinetic energy of a projectile (2) is absorbed in order to avoid rupture of the strap or connection between a rope (3) and a grapnel (5) that is integrated to the projectile.
