Inherently thin single width chain

摘要

An invention is disclosed comprising a cutting chain of links that pivot without longitudinal disarticulation, yet are connected without reliance on separate connections. Lateral dislocation of the links of the cutting chain is prevented by placement of the cutting chain in a channel, which guides the cutting chain along its operational path and provides resistance against normal load. The channel may be retractable and/or comprised of lubricious, heat absorbing materials. The blade may be flexible in order to cut a variable kerf. The invention further comprises a power train and drive train, designed to optimize the cutting chain for one of many applications.

主权项

1. A chain saw blade link comprising
(i) a top part having a blade; (ii) a bottom part having a drive cog engagement notch; (iii) a first side; (iv) a second side; (v) a round feature extending downward from the top part and inward from the first side towards the center of the link; (vi) a hook feature extending upward from the bottom part and outwards from the second side; and (vii) a complementary recess shaped to receive an adjacent hook feature, wherein when an adjacent link articulates away from the chain saw blade link on a convex path, the complementary recess receives the adjacent hook feature a complementary recess shaped to receive an adjacent hook feature, wherein when an adjacent link pivots away from the chain saw blade link on a convex path, the complementary recess receives the adjacent hook feature and is completely filled by the adjacent hook feature when the link and the adjacent link are at maximum degree of pivot.
