ABSTRACT:
The safety frame comprises a rigid, free-standing frame which is held by the hands hanging straight down from the shoulders. The center of gravity of the open space in the center of the frame defined by the frame is occupied by the user and extends through the user's parafrontal plane. The space inside the frame is of sufficient size to provide knee and hip clearance during the entire squatting motion. The lifter's hands grip the frame on either side of the body at points lying in the parafrontal plane and the weights are attached to the frame on either side of the hands, also on points lying in the parafrontal plane, with the weights in close proximity to the user's body.
The frame is rectangular in configuration and includes parallel front and rear bar elements and at least one straight left bar element and at least one straight right bar element extending perpendicular to the parafrontal plane and interconnecting the front and rear bar elements. The right and left bar elements support rods that extend outwardly for support weights. Within the rectangular frame there are two handgripping members with the midpoints thereof being closer to the user than the rods that support the weights. The handgripping members are parallel to the left and right bar elements.
