spaced from the intersection of plates 82 84 and forms an acute angle with plate 82 in this embodiment the third elongated flat member 86 is resilient and defines a biasing member the word u201c bias u201d is used to denote the force that arises when a resilient member at rest is forcibly displaced a u201c biasing member u201d is one that is made of resilient material in whole or in part that when deflected will apply a restoring force against the source of deflection when a biasing member is spaced from a fixed member or another biasing member and an object is placed between such member that displaces or alters the position of the biasing member at rest the biasing member or members will clamp the object with a force that resists removal of the object the word plate means a substantially flat elongated member that relative to a biasing member has more resistance to elastic deformation thus providing structural strength to the post the resistance may be due to the thickness of the member s type of material or other factors that affect the modules of elasticity the distal edge 90 of biasing member 86 is spaced from the elongated substantially flat structural plate 84 at a pre determined dimension distance or space shown at 92 at least a portion of biasing member 86 is resilient and biases the distal edge.
