STACKABLE FASTENER

摘要

A stackable fastener is provided for mounting to a substrate having a non-threaded hole or for affixing to similar fasteners. The stackable fastener includes a body having a central bore, and a force member rotatable within the body's central bore. In addition, the fastener includes a plurality of fingers which extend axially from the fastener's body. Rotation of the force member causes the fingers to extend radially outward to lock within a substrate hole or within the central bore of a similar stackable fastener.

1. A stackable fastener comprising:
a body having a central bore defining a central axis, said bore having a distal end and a proximal end with said central bore being tapered to have a diameter smaller at the bore's proximal end than the bore's distal end; a plurality of flexible fingers extending axially and distally from said body at said bore's distal extremity; a force member within said bore and fingers and rotatable about said body's central axis, said force member forcing said fingers radially outward when said force member is rotated to a first rotational position to push said fingers outward, and said fingers retracting inward when said force member is rotated to a second rotational position to not push said fingers outward in said central bore; and said fingers and bore constructed so that the stackable fastener is stackable upon like stackable fasteners wherein said fingers are sized to slide into a stackable fastener's central bore when said force member is positioned in a first position and said fingers are positioned inward, and said fingers are sized to lock within a stackable fastener's central bore when said force member is positioned in a second position and said fingers are positioned outward.
