Fitness Bar

Abstract

A weight attachment mechanism for a barbell; the attachment mechanism may include: a base including a receiving end and a mounting end; a fixed arm; an opening arm; and a sheath having an inner surface and an outer surface. The fixed arm and the opening arm may be configured to be mounted to the mounting end of the base. The opening arm may be movable relative to the fixed arm in order to receive a weight between the fixed arm and the opening arm. The inner surface of the sheath may be configured to fittingly engage at least a portion of the base. The receiving end of the base may be configured to attach to an end of the barbell.

The invention claimed is: 
     
         1 . A weight attachment mechanism for a barbell, the attachment mechanism comprising:
 a base comprising a receiving end and a mounting end;   a fixed arm;   an opening arm; and   a sheath having an inner surface and an outer surface,   wherein the fixed arm and the opening arm are configured to be mounted to the mounting end of the base,   wherein the opening arm is movable relative to the fixed arm in order to receive a weight between the fixed arm and the opening arm,   wherein the inner surface of the sheath is configured to fittingly engage at least a portion of the base, and   wherein the receiving end of the base is configured to attach to an end of the barbell.   
     
     
         2 . The weight attachment mechanism of  claim 1 , wherein the fixed arm and the opening arm each comprise a body portion and a mounting portion extending from the body portion in the direction of the base, wherein the body portions of the fixed arm and the opening arm define a first space configured to receive the weight therein, and wherein the mounting portions of the fixed arm and the opening arm are configured to be mounted to the mounting end of the base. 
     
     
         3 . The weight attachment mechanism of  claim 2 , wherein the mounting end comprises a first tab and a second tab defining a second space therebetween, and wherein the second space is configured to receive the mounting portions of the fixed arm and the opening arm therein. 
     
     
         4 . The weight attachment mechanism of  claim 3 , wherein the first tab and the second tab each have a pair of apertures, the pair of apertures on the first tab corresponding with the pair of apertures on the second tab. 
     
     
         5 . The weight attachment mechanism of  claim 4 , wherein the mounting portions of the opening arm and the fixed arm each comprise an aperture, each aperture aligning with one of the apertures of both the first and second tabs. 
     
     
         6 . The weight attachment mechanism of  claim 5 , wherein pins extend through each of the aligned apertures, fastening the opening arm and the fixed arm to the mounting end of the base. 
     
     
         7 . The weight attachment mechanism of  claim 2 , wherein an outer surface of the mounting portion of the opening arm is rounded so as to permit the rotation of the opening arm relative to the fixed arm. 
     
     
         8 . The weight attachment mechanism of  claim 2 , wherein the mounting portion of the opening arm extends a first length from the body portion of the opening arm and the mounting portion of the fixed arm extends a second length from the body portion of the fixed arm, and wherein the second length is longer than the first length. 
     
     
         9 . The weight attachment mechanism of  claim 8 , wherein the mounting end of the base comprises a slot configured to receive at least a portion of the mounting portion of the fixed arm therein. 
     
     
         10 . The weight attachment mechanism of  claim 1 , wherein the base further comprises a threaded portion between the receiving end and the mounting end. 
     
     
         11 . The weight attachment mechanism of  claim 10 , wherein at least a portion of the inner surface of the sheath is threaded, corresponding to the first threaded portion of the base. 
     
     
         12 . The weight attachment mechanism of  claim 1 , wherein the weight is a dumbbell. 
     
     
         13 . The weight attachment mechanism of  claim 1 , wherein the weight is a fitness ball. 
     
     
         14 . A weightlifting assembly comprising:
 a first bar having a first end and a second end and a second bar having a first end and a second end; and   at least one weight attachment mechanism comprising:
 an attachment portion having a connecting end and a weighted end; and 
 a locking sheath, 
   wherein the connecting end of the attachment portion is configured to be mounted to the first end of the first bar or the first end of the second bar,   wherein the weighted end is configured to receive a weight therein,   wherein the locking sheath is configured to lock the weight within at least a portion of the weighted end, and   wherein the second end of the first bar and the second end of the second bar are configured to be attached to one another.   
     
     
         15 . The weightlifting assembly of  claim 14 , wherein the weighted end comprises a fixed arm and an opening arm movable relative to the fixed arm in order to receive the weight therebetween. 
     
     
         16 . The weightlifting assembly of  claim 15 , wherein the locking sheath is configured to be rotatably mounted to the attachment portion so as to cover at least a portion of the fixed arm and the opening arm so as to prevent the opening arm from moving. 
     
     
         17 . The weightlifting assembly of  claim 15 , wherein the at least one weight attachment mechanism further comprises a pair of locking pins configured to be received through at least a pair of corresponding apertures located on the attachment portions of the fixed arm and the opening arm. 
     
     
         18 . The weightlifting assembly of  claim 15 , wherein a surface of the opening arm is rounded so as to permit the opening arm to rotate relative to the fixed arm. 
     
     
         19 . The weightlifting assembly of  claim 14 , wherein the weight is a dumbbell. 
     
     
         20 . The weightlifting assembly of  claim 14 , wherein the weight is a fitness ball.
