Barbell Lock Collar

Abstract

The present example provides a barbell lock collar that installs axially on a barbell bar. Axially directed pressure on the barbell lock collar causes curved shoes on the interior of the barbell lock collar to engage or disengage through radial motion of the curved shoes. Axial motion also causes a visual indicator to show if the barbell lock collar is engaged or disengaged, as little force is required to operate the barbell lock collar.

1 . A barbell lock collar for securing a weight on a barbell comprising:
 a first hub including:
 at least one first hub brake pocket; 
 at least one magnet disposed in the first hub brake pocket; 
   a second hub attached to the first hub including:
 at least one second hub brake pocket; 
 at least one magnet disposed in the second hub brake pocket; 
   at least one brake assembly disposed in the first hub brake pocket, and the second brake pocket;   a sleeve encircling the first and second hub, and including at least three protrusions positioned to actuate the brake assembly.   
     
     
         2 . The barbell lock collar for securing a weight on a barbell of  claim 1 , further comprising a green band disposed in a groove of the first hub 
     
     
         3 . The barbell lock collar for securing a weight on a barbell of  claim 1 , further comprising a red band disposed in a groove of the second hub 
     
     
         4 . The barbell lock collar for securing a weight on a barbell of  claim 1 , further comprising a label disposed on a flat surface of the second hub 
     
     
         5 . The barbell lock collar for securing a weight on a barbell of  claim 1 , further comprising a base pad disposed on a flat surface of the first hub 
     
     
         6 . The barbell lock collar for securing a weight on a barbell of  claim 1 , in which there are three brake assemblies, three first hub brake pockets, and three second hub brake pockets. 
     
     
         7 . The barbell lock collar for securing a weight on a barbell of  claim 1 , in which the brake assembly includes:
 a mount having top and bottom guide tabs, and an aperture including a toggle with a pin pivotally coupled to the mount, the toggle protruding through an aperture;   a shoe having an aperture for receiving an end of the toggle   a first hinge coupling the mount to the shoe   a second hinge parallel to the first hinge coupling the mount to the shoe   a first magnet disposed in the shoe   a second magnet disposed in the shoe   a pad attached to the shoe   
     
     
         8 . A barbell lock collar that installs axially on a barbell bar comprising:
 a sleeve for applying an axially directed pressure;   a hub and brake assembly including:
 a hub including actuators for converting an axial force to a radial force; 
 a plurality of curved shoes on the interior of the hub engage or disengage through radial motion of the curved shoes. 
   
     
     
         9 . The barbell lock collar that installs axially on a barbell bar of  claim 8  further comprising a visual indicator to show if the barbell lock collar is engaged or disengaged.
