BELTS, CABLES, OR ROPES, PREDOMINANTLY USED FOR DRIVING PURPOSES; CHAINS; FITTINGS PREDOMINANTLY USED THEREFOR
Definition statement

This place covers:

Belts, e.g. V-belts, cables, ropes or chains that are specially adapted for transferring power/force from an input point to an output point to move or drive at least one mechanical part.

The belts, cables, ropes or chains being either

formed into a loop that is intended to travel around an endless path and engage two or more pulleys, sprockets or similar rotating elements and transfer power/force while travelling along its path; or

an elongated element that is intended to travel backward or forward along a path to transfer power/force between one point along its length to another point along its length, e.g. from a drum to a load.

Chains, e.g. hauling- or hoisting-chains, that are not specially adapted for transferring power/force.

Fittings and attachments primarily intended to be connected to or used with the above types of belts, cables, ropes or chains. These include:

means for fastening ends of belts together to form closed loops, e.g. fastenings for conveyor belts or V-belts;

means for fastening cables or ropes to one another or to other objects;

caps or sleeves for fixing on cables or ropes;

means for coupling chains;

components of chains, e.g. shackles, swivels, chain joints, chain links or chain bushes;

hooks as integral parts of chains.

Driving-belts (V-belts F16G 5/00; conveyor belt B65G)

Although this belt looks like a chain, it is considered and classified as being a V-Belt because of the interaction of the chain with the pulley. The engagement of the pins with the pulley is made on the extrimity of the pins and is similar with the side contact engagement that a V-Belt has with a pulley.
