DEFINITION

Classification: 242/608.6

Snap fit:

(under subclass 608.2) Subject matter wherein the joining means connecting the rim to a winding surface or another rim includes an element on one of the spool components adapted to be compressed during an initial stage of assembly until the joint is nearly completed whereupon the compression is released, often with an audible sound.

(1) Note. This type of joint may be temporary or permanent and is usually formed as a deflected tongue or biased ball detent having a surface transverse to the direction of assembly of the components, which surface induces stress until the transverse surface is accommodated.
