Benefits of technology

[0011] Therefore an object of the present invention is to provide fitness equipment combining free-weights and stack-weights to expand the types of fitness training available.
[0012] Another object of the present invention is to reduce time required to change the weights associated with free-weight training.
[0013] Another object of the present invention is to provide automatic support of a combined free-weight and stack-weight apparatus upon loss of control of the free-weight.

Problems solved by technology

One disadvantage limiting use of free-weights is the need for one or more spotters, especially in strength regimens that push the strength and endurance limits of the user.
This is a safety concern if spotters are not immediately available since the user may be unable to safely lift the weight to a support device.
Even when spotters are available, they may not recognize an unsafe condition, or, their response may not be quick enough to prevent injury.
Another limitation of free-weight equipment is the time required to add or remove free-weights to the free-weight assembly.
The freedom of motion of stack-weight apparatus is limited unless cables are used, and even then no overhead support is provided.

Embodiment Construction

[0039] The following is a description of the preferred embodiments of fitness apparatus combining free-weight and stack-weights to provide improved functionality and performance for weight-training equipment.

[0040]FIGS. 1, 2 and 3 show the front elevation, side elevation and top views respectively of embodiment 101 of the fitness apparatus. The apparatus provides at least two means of providing lift resistance; free-weight assembly or barbell 102 comprising free-weights 103A, 103B mountable on free-weight bar 105 and adjustable resistance means 107 comprising stack-weight cables 109A, 109B connected between bar 105 and stack-weight assemblies 111A, 111B. The apparatus also provides an overhead conditional support means 113 such as support cable assemblies 115A, 115B connected between bar 105 and weight-responsive engagement assemblies 117A, 117B engageable to support stands 119A, 119B of the frame 145.

[0041] Bar 105 of free-weight assembly 102 provides a means for an operator (not...

Abstract

A combined free and stack-weight fitness apparatus utilizes a combination of free-weights and stack-weight assemblies to provide multi-mode fitness training. The total training resistance is a combination of free-weights attached to a barbell and stack-weight resistance transmitted to the barbell by cables. A pair of overhead cables attached to the barbell provide vertical support until a substantial portion of the weight on the barbell is borne by the operator.

Description

[0001] This application claims the benefits of US Provisional Application No. 60 / 492,925 filed Aug. 06, 2003 and PCT application No. PCT / US2004 / 025063 filed 04 Aug. 2004.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to the field of fitness equipment and, more particularly, to a fitness equipment utilizing both free-weights and stack-weights. [0004] 2. Description of the Related Art [0005] Despite the variety of exercise and muscle-building equipment and activities available, free-weight lifting continues to be the workout method of choice for many athletes. Free-weight lifting allows unrestrained motion during lifting, closely approximating application of human strength in many recreation and sporting activities. Selection of weights utilized in free-weight lifting is highly repeatable as compared to machines employing levers, cams, and resistance elements such as springs and hydraulic or pneumatic cylinders. Also, free-weights pro...
