Abstract
A weight horn is supported on a bearing housing that slides along two vertical guide rails. The upper and lower ends of the vertical guide rails are connected to tubular sleeves that slide along horizontal guide rails, which are enclosed by a rectangular frame. A roller pad extends from the opposite side of the weight horn, perpendicular to the horizontal guide rails and over a platform containing an adjustable seat, calf support and foot pads. The weight lifter performs the movement by standing upright with his/her legs positioned between the calf support and foot pads, wrapping his/her arms around the roller pad, and squatting onto the seat. The combination of vertical and horizontal guide rails allows the weighted roller pad to travel a curved path downward and backward as the lifter descends into the squat position. The dual rail configuration for both the vertical and horizontal guide rails prevents jamming of the mechanisms if the weight lifter twists his/her torso during the squat.
Description
- The present invention generally relates to the field of exercise equipment, and more particularly to weighted exercise machines.
- In doing a conventional front squat movement, a barbell is typically supported against the chest/shoulder area of the front torso. As currently performed, the front squat movement demands that the weight lifter manually grip and hold the barbell against his/her body, typically in the cross-armed fashion, as depicted in U.S. Pat. No. 6,135,932. While a shoulder harness, such as that described in U.S. Pat. No. 5,472,398, can also be used, it still requires that the barbell be manually gripped. In both cases, a slip of the lifter's hands can cause him/her to lose control of the barbell, resulting in potential injury. A principal objective of the present invention is to provide a safer, more efficient means for doing front squat exercises.
- In the present invention, a weight horn is supported on a bearing housing that slides along two vertical guide rails. The upper and lower ends of the vertical guide rails are connected to tubular sleeves that slide along horizontal guide rails, which are enclosed by a rectangular frame. A roller pad extends from the opposite side of the weight horn, perpendicular to the horizontal guide rails and over a platform containing an adjustable seat, calf support and foot restraints. The weight lifter performs the movement by standing upright with his/her legs positioned between the calf support and foot pads, wrapping his/her arms around the roller pad, and squatting onto the seat.
- The combination of vertical and horizontal guide rails in the present invention allows the weighted roller pad to travel a curved path downward and backward as the weight lifter descends into the squat position. As shown in
FIG. 1 , in order for theroller pad 42 to follow a curved path as the lifter squats and stands, theroller pad 42 must be free to move horizontally and vertically at the same time, which the orthogonal combination rail configuration of the present invention enables. Furthermore, the dual rail configuration for both the vertical and horizontal guide rails prevents jamming of the mechanisms if the weight lifter twists his/her torso during the squat. Optionally, the roller pad can also be made to rotate axially and/or to revolve around a swivel arm for additional multi-directional movement. - The foregoing summarizes the general design features of the present invention. In the following sections, specific embodiments of the present invention will be described in some detail. These specific embodiments are intended to demonstrate the feasibility of implementing the present invention in accordance with the general design features discussed above. Therefore, the detailed descriptions of these embodiments are offered for illustrative and exemplary purposes only, and they are not intended to limit the scope either of the foregoing summary description or of the claims which follow.

Thestanchions 18 19 and the cross braces 20 21 comprising theupright frame 17 are preferably tubular steel. As depicted inFIG. 2B , thelower cross brace 21, which can include an uprightlower panel 22, connects theinterior side 12 of theupright section 11 to theinner base side 15 of thebase section 14 at a right angle. - The
upright section 11 also comprises a dynamicweight carriage assembly 23, comprising a pair of parallel, rigid, generally horizontal,transverse guide rods 24 25, consisting of a toptransverse guide rod 24 and a bottomtransverse guide rod 25. Thetransverse guide rods 24 25 are preferably stainless steel, and they can extend from thefront stanchion 18 to therear stanchion 19. Alternatively, as depicted inFIG. 2B , thetransverse guide rods 24 25 can extend from thefront stanchion 18 to amedial beam 19A located between thefront stanchion 18 and therear stanchion 19 and extending generally vertically from theupper cross brace 10 to thelower cross brace 21. - Slidably mounted on the

FIG. 9 . Instead of locating the racking pegs 57 on a dedicated racking beam, the racking pegs 57, in the form of generally horizontal hooks, are located on thefront stanchion 18, so that the weight housing can be racked up by putting theweight bar 37 over one of the hooked racking pegs 57, as indicated by the arrow. - As depicted in
FIGS. 3A-3C , thebase section 14 comprises a generally horizontal, planar base frame orbase platform 36. Thebase section 14 further comprises an adjustable, generallyhorizontal seat 53, an adjustable, generallyvertical calf support 54, and two adjustable, generallyhorizontal foot restraints 55. The user of theexercise machine 10 stands with his/her two feet in thefoot restraints 55 and his/her two calves against the calf supports 54, and from this standing position squats down onto theseat 53 while grasping the weight handling means 35, so as to perform a front squat. - As depicted in
FIGS. 10A-10C , anergonomic padding sleeve 61 can optionally be substituted for the substantially cylindrical padding sleeve shown inFIG. 2A andFIGS. 6-9 , and its mounting to theweight bar 37 in substantially the same as shown in the latter figures. Theergonomic padding sleeve 61 comprises a generally horizontal, convex,upper sleeve 62, which transitions in the forward direction into a generally vertical,grip flange 63. Thegrip flange 63, in turn, transitions in the rear direction into a central generally horizontal, bulbous, arcuate,sternum support 64, which projects generally downward between two concave arm recesses 65. The user would insert his/her arms under thesleeve 61 into therecesses 65 and grasp thegrip flange 63 with his/her hands in order to lift theweight bar 37 in performing the front squat exercise. - Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that many additions, modifications and substitutions are possible, without departing from the scope and spirit of the present invention as defined by the accompanying claims.
