Weight plate with detachable locking cartridge
First Claim
1. A weight plate to be releasably attached to a weight plate lifting element of physical fitness weight lifting equipment, said weight plate comprising:
- a plate body having a hole formed therein for receipt of the weight plate lifting element;
an external locking cartridge located entirely outside said plate body, said locking cartridge detachably connected to one side of said plate body; and
a locking pin sliding reciprocally through each of said external locking cartridge and said plate body so as to be displaced relative to the hole in said plate body,said external locking cartridge including a housing, a pivot located within said housing, and a pivotal lever switch arm that is connected to said pivot and coupled to said locking pin within said housing, said pivotal lever switch arm being surrounded by and projecting outside said housing at which to receive a force so that said pivotal lever switch arm rotates within said housing at said pivot and moves within said housing between an on position for causing said locking pin to slide in a first direction into the hole in said plate body at which to be attached to the weight plate lifting element and an off position for causing said locking pin to slide in an opposite direction out of the hole in said plate body so as to be detached from the weight plate lifting element.

Abstract
A weight plate having a detachable locking cartridge by which the weight plate is releasably connected to a lifting element (e.g., a center post) whereby one or more weight plates carried by the lifting element may be lifted by a user. The weight plate also has a plate body with a central bore in which to receive the lifting element. In one embodiment, the detachable locking cartridge is mounted flush against one side (e.g., the bottom) of the weight plate body so as to lie entirely external to the plate body. In an alternate embodiment, the detachable locking cartridge includes a stabilizer extension that is received within a cavity recessed in the one side of the plate body. The detachable locking cartridge includes a manually-accessible toggle lever switch arm that is adapted to rotate within a housing of the cartridge between locked and unlocked positions to thereby control the displacement of a locking pin relative to the lifting element within the central bore of the plate body.

11. A weight plate to be releasably attached to a weight plate lifting element of physical fitness weight lifting equipment, said weight plate comprising:
-
a plate body having a hole formed therein for receipt of the weight plate lifting element, a cavity formed in one side of said plate body, and a stud hole formed in said cavity; a locking cartridge having a first portion lying flush against the one side of said plate body and a second portion received inwardly of the cavity in said one side, said locking cartridge also having an anchor stud projecting therefrom for receipt by the stud hole formed in the cavity of said plate body; at least one fastener removably attached to the one side of said plate body by way of the first portion of said locking cartridge by which said locking cartridge is detachably connected to said plate body; and a locking pin disposed in perpendicular alignment with the one side of said plate body, said locking pin sliding reciprocally through each of said locking cartridge and said plate body so as to be displaced relative to the hole in said plate body, said locking cartridge including a pivot and a pivotal lever switch arm that is connected to said pivot and coupled to said locking pin within said detachable locking cartridge, said pivotal lever switch arm being surrounded by and projecting outside said locking cartridge at which to receive a force so that said pivotal lever switch arm rotates at said pivot and moves within said locking cartridge between an on position for causing said locking pin to slide in a first direction into the hole in said plate body at which to be attached to the weight plate lifting element and an off position for causing said locking pin to slide in an opposite direction out of the hole in said plate body so as to be detached from the weight plate lifting element. - View Dependent Claims (12)
