Abstract
A weight holder device for use in combination with a weight lifting exercise apparatus that includes a stack of several plates of equal size and weight and each having a vertical central through hole to receive a vertical lifting rod with a horizontal through bore and a horizontal hole extending from the central hole to a side of the plate. The device includes a shear pin removably inserted through both the horizontal hole and the through bore and supporting a variable number of upper plates of the stack. A protruding end of the pin has an axially adjustable holder mounted thereon for releasably and tightly suspending a fractional weight therefrom, between two spaced flanges secured to and radially extending from the pin. At least one of the flanges has a locking member and is axially adjustable relative to the other flange and along the pin to releasably engage and tightly retain the weight between them via the locking member in unlocking and locking configuration respectively.
