A fastener member is disclosed, having a plurality of headed stems adjoining and projecting from a base. The headed stems are arranged in a pattern on the base, which pattern tends to increase the disengagement force in the shear direction.
Claims5
An interengaging fastener member comprising a base and a plurality of headed stems arranged on the base, each of the headed stems including a stem projecting from the base, and a head connected to a distal end of the stem, the arrangement of headed stems comprising:
- a first set of headed stems arranged in a predetermined spaced relationship, adjacent headed stems in the first set being separated by a first distance, a plurality of headed stems from the first set defining at least two adjacent polygonal patterns;
- and
- a second set of headed stems not in the first set of headed stems, headed stems in the second set being separated from adjacent headed stems in the first set by a distance not equal to the first distance, at least one of the headed stems in the second set located within each of the polygonal patterns.
An interengaging fastener member comprising a base, and a plurality of headed stems arranged on the base in a predetermined spaced relationship, each of the headed stems including a stem projecting from the base, and a head connected to a distal end of the stem, wherein the headed stems include:
- (a) a plurality of first rows of headed stems arranged in a straight line across the base;
- and
- (b) a plurality of second rows of headed stems alternating with the plurality of first rows of headed stems adjacent and substantially parallel to the first rows, the second rows of headed stems having a sinusoidal pattern relative to the first rows.
