Abstract:
1. Physical fitness apparatus, comprising: a first weight plate having a bore hole formed vertically therethrough and an internal bore running transversely therein and communicating with said bore hole; a second weight plate to be detachably connected to said first weight plate and having a bore hole formed vertically therethrough and an internal bore running transversely therein and communicating with said bore hole; a first connector located in the bore hole through said first weight plate and a second connector located in the bore hole through said second weight plate; each of the first and second connectors of said first and second weight plates having a hollow head at one end thereof and an aperture formed in said hollow head and axially aligned with a respective one of the internal bores in said first and second weight plates, each of said first and second connectors also having a coupling tail located at the opposite end thereof and a coupling hole formed in said coupling tail, the coupling tail of the first connector located in the bore hole of said first weight plate extending below said first weight plate for receipt within the hollow head of the second connector located in the bore hole of said second weight plate; a locking pin mounted for reciprocal movement between unlocked and locked positions within the internal bore of each one of said first and second weight plates, said locking pin having a locking slot formed therein; and a lever arm communicating with each locking pin of each one of said first and second weight plates at the locking slot formed in said locking pin, each lever arm moving between a first position and a second position to correspondingly apply one of a pushing force or a pulling force to said locking pin, the lever arm which communicates with the locking pin of said second weight plate moving from the first position to the second position to exert the pushing force on said locking pin at said locking slot thereof and thereby cause said locking pin to move from said unlocked position to said locked position and ride through the internal bore in said second weight plate for receipt by the aperture formed in the hollow head of said second connector and the coupling hole formed in the coupling tail of said first connector received by the hollow head of said second connector, whereby said first weight plate is detachably connected to said second weight plate.
