Embodiment Construction

[0048] The following is a description of a preferred embodiment of a barbell positioning device that provides the user with unrestrained "free weights", but provides dynamic positioning and "walk-away" safety locking features.

[0049] figure 1 It is the isometric projection diagram of the right front quadrant of embodiment 101 of the barbell protection device. The apparatus includes a support frame 102 having a frame 103, a tower shell 137 and pivoting weight support booms 105A and 105B. Rope assemblies 107A and 107B supported by pulleys 109A and 111A of boom 105A and pulleys 109B and 111B of boom 105B are secured to barbell ends 113A and 113B of a free weight assembly (eg, barbell 115 ). Releasable attachments, such as cable connection assemblies 117A and 117B (best shown in FIG. 7), connect respective cable assembly end portions 119A and 119B to barbell ends 113A and 113B.

[0050] Opposite cable assembly end portions 121A and 121B (121B best shown in FIG. 6) are connecte...

Abstract

A self-spotting apparatus for free-weights (101) provides two cable assemblies (107A, 107B) with one end of each cable assembly attached to a free-weight assembly (115) and the opposite end attached to respective linear weight-support assemblies (123A, 123B) via respective weight-responsive engagement blocks (125A, 125B). Guide rods (127A, 127B) allow vertical motion of the engagement blocks and maintain engagement orientation relative to the support assemblies. The engagement blocks engage the respective support assemblies for static support of the free-weight assembly. Lifting of the substantial weight of the free-weight assembly and activation of disengagement bias is required to disengage the engagement blocks from the respective support assemblies to allow free motion of the free-weight assembly. The apparatus provides self-spotting for barbells (115) and dumbbells (247A).

Description

technical field [0001] The present invention relates to the field of sports equipment and, more particularly, to self-spotting devices for free weights. Background technique [0002] Despite the variety of sports and muscle-building machines and activities available, free weight lifting has always been the workout of choice for many athletes. In weightlifting, free weights are lifted without restraint of motion, very close to the use of human strength in many recreational and sporting activities. The choice of weights used in free weight lifting is highly repeatable when compared to machines that use levers, cams, and resistance elements such as springs, hydraulic cylinders, or air cylinders. Additionally, the consistent resistance provided by free weights is independent of mechanical and other wear and tear. [0003] One disadvantage of limiting the use of free weights is the need for one or more supervisors, especially in strength training situations...
