Abstract
A multiple link transmission chain composed of interconnected identical links, having identical ends which are angularly disposed with respect to each other by 90 degrees in relation to the longitudinal axis.
Claims8
A multiple link chain composed of a plurality of identical links, each comprising:
- a link body having a longitudinal axis and first and second link ends spaced along the axis, each identical to the other and each angularly disposed with respect to the other about the axis by 90 degrees;
- each link end having a plurality of spaced members extending along the axis;
- an opening in each of said members aligned along an axis orthogonal to the longitudinal axis, the orthogonal axis of one link end being orthogonal to the axis of the other link end;
- `said aligned openings through said members accepting a pivot pin;
- a protrusion at each link end and each outwardly extending from the outer one of the associated spaced members, each symmetrically disposed about the associated orthogonal axis and adapted for driving engagement with a sprocket wheel;
- and
- each of said link ends being mateable to either link end of adjacent links by interdigitated connection of the spaced members of the adjacent links.
