Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 477 words
A safety device for use in weightlifting exercise wherein the user squats and rises to lift weights with both hands, said device comprising the following characteristics simultaneously: a. a rigid, free standing, quadrilaterally symmetrical frame, b. said frame defining an open space of sufficient size so that the user's body can be positioned in it without interferring with the frame, and without any part of the frame being above any part of the user's body at any time during the squat exercise, c. said frame is rectangular in configuration and includes front and rear bar elements extending parallel to said parafrontal plane and at least one straight left side bar element and at least one straight right side bar element extending perpendicular to said parafrontal plane and interconnecting said front and rear bar elements, d. said frame having mounted horizontally thereon a left side weight attaching member and a right side weight attaching member, both for the purpose of attaching weights to the frame horizontally, e. said left side weight attaching member and said right side weight attaching member are rigidly fixed to the respective midpoints of said left side bar element and said right side bar element, f. said left and right side weight attaching member extend horizontally out on their respective sides, extending perpendicularly to the left and right side bar elements to which they are fixed, g. said frame further having mounted thereon a left side handgripping member and a right side handgripping member with the midpoints of said handgripping members being closer to the user's body then the weight attaching members, h. said left and right side weight attaching members, the midpoints of said left and right side handgripping members, the midpoints of said straight left and right side bar elements, and the center of gravity of said entire device lying in the parafrontal plane of the user's body when the user is standing fully erect holding the device down at his sides at arms's length, i. when weights are attached to said left and right side weight attaching members, the center of gravity of each of the attached weights will lie in the parafrontal plane of the user's body when the user is standing fully erect holding the device down at his sides at arms's length, j. the center of gravity of said entire device remaining in the same vertical plane as the center of gravity of the user's body during the squatting movement, k. furthermore in the preferred form said left side handgripping member and right side handgripping member are located respectively at midpoints of an inner left side bar element and an inner right side bar element, said inner left and right side bar elements being closer to the user's body than said left and right side bar elements and extending parallel to said left and right side bar elements.
Claim 2
Dependent Claim 477 words
A safety device for use in weightlifting exercise wherein the user squats and rises to lift weights with both hands, said device comprising the following characteristics simultaneously: a. a rigid, free standing, quadrilaterally symmetrical frame, b. said frame defining an open space of sufficient size so that the user's body can be positioned in it without interferring with the frame, and without any part of the frame being above any part of the user's body at any time during the squat exercise, c. said frame is rectangular in configuration and includes front and rear bar elements extending parallel to said parafrontal plane and at least one straight left side bar element and at least one straight right side bar element extending perpendicular to said parafrontal plane and interconnecting said front and rear bar elements, d. said frame having mounted horizontally thereon a left side weight attaching member and a right side weight attaching member, both for the purpose of attaching weights to the frame horizontally, e. said left side weight attaching member and said right side weight attaching member are rigidly fixed to the respective midpoints of said left side bar element and said right side bar element, f. said left and right side weight attaching member extend horizontally out on their respective sides, extending perpendicularly to the left and right side bar elements to which they are fixed, g. said frame further having mounted thereon a left side handgripping member and a right side handgripping member with the midpoints of said handgripping members being closer to the user's body then the weight attaching members, h. said left and right side weight attaching members, the midpoints of said left and right side handgripping members, the midpoints of said straight left and right side bar elements, and the center of gravity of said entire device lying in the parafrontal plane of the user's body when the user is standing fully erect holding the device down at his sides at arms's length, i. when weights are attached to said left and right side weight attaching members, the center of gravity of each of the attached weights will lie in the parafrontal plane of the user's body when the user is standing fully erect holding the device down at his sides at arms's length, j. the center of gravity of said entire device remaining in the same vertical plane as the center of gravity of the user's body during the squatting movement, k. furthermore in the preferred form said left side handgripping member and right side handgripping member are located respectively at midpoints of an inner left side bar element and an inner right side bar element, said inner left and right side bar elements being closer to the user's body than said left and right side bar elements and extending parallel to said left and right side bar elements.
Claim 3
Dependent Claim 29 words
The safety device of claim 1 further characterized in that: a. furthermore in the preferred form the underside of each weight attaching member is reinforced by a plate fillet.
Claim 4
Dependent Claim 93 words
The safety device of claim 1 further characterized in that: a. furthermore in the preferred form the left side weight attaching member is fixed to the said left side bar element such that weight plates can be attached both on the left side and on the right side of said left side bar element, and likewise the right side weight attaching member is fixed to said right side bar element such that weight plates can be attached both on the left side and on the right side of said right side bar element.
