Abstract:
An inflatable line includes strands, at least one being an inflatable bladder adapted to receive a fluid or a gas for making the line firm and less flexible. The strands form a rope of natural or synthetic fibers and the bladder is of a natural material, a synthetic material, rubber, nylon, plastic, or KEVLAR<(R)>. A line system is also provided and includes the line and a pump fluidically connected to the bladder. The pump can be a hand pump having a bulb, a connecting tube fluidically connected to the bladder, and a valve fluidically connecting the bulb to the connecting tube for controlling inflation and deflation of the bladder. The connecting tube can be removably connected to the bladder and/or to the valve. The bulb can transmit air or fluid. The pump can be a compressed air pump with a compressed air container, for example, a CO2 cartridge.
