Patent attributes
Weight plate locking and lifting systems by which one or more weight plates are detachably connected to a lifting handle bar to enable the weight plates to be removed from or returned to a nearby storage rack without having to lift, transport and handle the weight plates. Each weight plate includes a toggle lever switch arm that is coupled to a locking pin. Each weight plate also includes a radially-extending locking cavity within which to removably receive the lifting handle bar. When the toggle lever switch arm is moved to a locked position, the locking pin slides in a first direction through the weight plate and into engagement with the lifting handle bar within the locking cavity. When the toggle lever switch arm is moved to an unlocked position, the locking pin slides in an opposite direction out of engagement with the lifting handle bar.
