Abstract:
A snap fastener with an interlocking tab, comprising:an operative component and a securing component;the operative component having a deformable cantilever beam rigidly affixed to a base, the cantilever beam deforming to receive a catch member on the securing component when the operative component and the securing component are mated to form a snap fastener, such that the cantilever beam and the catch member constrain the relative movement of the two components in two directions that are orthogonal to each other;a cavity under the operative component, one wall of the cavity comprising the base and an opposite wall of the cavity comprising the deformable cantilever beam;the securing component having a protrusion adapted to fit into an open end of the cavity, so that when the operative component and the securing component are mated the relative movement of the two components is constrained by the two cavity walls in a third direction that is orthogonal to said two directions that are orthogonal to each other.
