A quick-release ratcheting mechanism for a weight lifting bar system. The present invention utilizes a ratcheting device in conjunction with ratchet teeth which are located on the inside surface of an aperture of individual weight components. As such, when the individual weight components are placed onto the present invention, the present invention ratcheting system engages the weight component teeth, subsequently creating a fixed and secure engagement. If the user desires to remove the individual weight component, a quick-release handle disengages the ratchet mechanism and allows free removal of an individual weight component. As a further feature the present invention, the preferred embodiment incorporates a unique passive interlocking means between each adjacently placed individual weight component and a unique geometric configuration which enhances the stability of the present invention.

1. A quick-release mechanism apparatus for a weight lifting bar, said weight lifting bar having at least two ends, said apparatus comprising: a receiving end, said receiving end being fixedly attached to said end of said weight lifting bar; a keyed protrusion member, said keyed protrusion member having a geometric cross-section, a hollowed portion therein, a channel, a front end and a back end, said hollowed portion having a hollowed back end and a hollowed front end, said front end being fixedly attached to said receiving end with an attachment means; a plurality of individual weight components, said individual weight components having an aperture located approximately in the center thereof, said aperture having a geometric configuration approximately the same as said geometric cross-section and a plurality of aperture teeth on at least one internal surface, wherein said aperture can readily receive said keyed protrusion member; a quick-release handle, said quick-release handle being pivotally mounted within said receiving end; and a ratchet mechanism, said ratchet mechanism being attached to said hollowed portion of said keyed protrusion member.2. An apparatus as claimed in claim 1 wherein said attachment means is a threaded screw.3. An apparatus as claimed in claim 1 wherein said geometric cross-section is triangular.4. An apparatus as claimed in claim 1 wherein said keyed protrusion member further comprises a unique protrusion extending from the exterior surface of said keyed protrusion member.5. An apparatus as claimed in claim 1 wherein said quick-release handle is a lever.6. An apparatus as claimed in claim 1 wherein said hollowed portion comprises at least one compression spring fixedly attached to said hollowed back end.7. An apparatus as claimed in claim 1 wherein said ratchet mechanism comprises, in combination: a plurality of wheel members, said wheel members having a plurality of teeth-like structures on the periphery of said wheel members, said wheel members being rotatably attached to said hollowed portion whereby said teeth-like structures are accessible from the outside of said hollowed portion through said channel when said wheel members are attached thereto and further engage said aperture teeth when said individual weight components are placed over said keyed protrusion member; and a ratchet locking device, said ratchet locking device having a front end, a back end and a plurality of recessed areas to readily receive said wheel members, said front end having a quick-release handle contact point, said back end having a compression spring contact point, said recessed areas having at least one protrusion protruding toward said wheel member whereby said protrusion engages said teeth-like structures when said ratchet locking device is engaged and said wheel members can only rotate in one direction.8. An apparatus as claimed in claim 1 wherein said ratchet mechanism comprises a ratcheting member, said ratcheting member having a top side, a bottom side, a front end and a back end, said top side having a plurality of angled slots to readily receive attachment pins, said back end having a compression spring contact point, said front end having a quick-release handle contact point, said bottom side having a plurality of teeth whereby when said ratcheting member is attached to said hollowed portion, said teeth are accessible through said channel.
