## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of Provisional Patent Application Ser. No. U.S. 60/670,765, filed 2005 Apr. 13 by the present inventor.


BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a multi-party, multi-purpose and collapsible fitness machine geared towards usage by three or more persons simultaneously performing various types of muscle building and toning as well as cardiovascular exercises.
2. Discussion of Prior Art
It is a well documented fact that there exist multitudes of exercise apparatus which in unison or individually can be used to perform various types of muscle building and toning as well as cardiovascular exercises. However, acquiring a selection of a multitude of individual exercise apparatus to perform all types of exercises requires a lot of floor space and a lot of money. This is beyond the means of most users of exercise machines. The multi-party, multi-purpose fitness machine is designed with this in mind and is geared towards the family unit where members of a family can work out together simultaneously on one simple efficient machine offering a wide range of exercises for building and toning various muscles of the body as well as for performing cardiovascular exercises to condition the heart. This invention advocates that a family that works out together stays fit and united forever.
If one were to examine many of the brochures and infomercials for fitness machines and if one were to visit sporting equipment outlets as well as most gyms, one would find that most multi-station exercise apparatus available on the market today are complicated as they all invariably use a set of complex cable and pulley systems for generating forces and securing variable weights to provide resistance. This complexity makes such fitness machines difficult to manufacture, set up and maintain and quite expensive as a result. In the present invention, the design bypasses this approach thereby completely eliminating the need for cables and pulleys. This in turn translates into reduced cost for manufacturing, set up and maintenance thus making the present invention much more affordable.
Most multi-station fitness machines require large floor areas and bigger headroom as a result of their complex makeup. This limits their acceptance by many users who cannot spare prime floor areas for such machines as gym space utilization efficiency (GSUE) of such machines gets excessively high. Gym space utilization efficiency or GSUE as it applies to multi-station fitness machines having capabilities for a variety of exercises is the ratio of the projected floor area occupied by such fitness machine divided by the maximum number of simultaneous users. For instance, if a multi-station fitness equipment occupies a projected floor area of 7 feet by 8 feet (56 sq. ft.) and a maximum of two people can use the equipment simultaneously, the GSUE then becomes 28 sq. ft. per user. If on the other hand, the multi-station fitness equipment can only be used by one person at any given time, the GSUE becomes 56 sq. ft. per person which basically limits the cost effectiveness of such multi-station fitness machine. My present invention occupies a projected floor area of approximately 6 ft. by 9 ft (54 sq. ft.) under maximum usage. It has capability for over thirty different exercises. It is designed to accommodate three or more users working on it simultaneously. A maximum of five users can work on it at the same time which gives it a GSUE of 11 sq. ft. per user thus ranking it among the top cost effective fitness machines to own.
Most multi-station exercise machines are not built for simultaneous use by multiple users. The fact that a fitness machine is multi-station does not necessarily translate into multi-usage where three or more people can simultaneously work on it. The multi-station capability is only for the variety of exercises that one individual can perform on the machine at any given time by changing the type of exercise to develop a specific set of muscles. Most do not have the capability for three or more people to simultaneously work out on the same machine. As explained above, the present invention is specifically designed to accommodate three or more users and as many as five users working on it simultaneously.
Most multi-station exercise machines are geared towards building and toning the different superficial muscles of the body with no accommodation for cardiovascular exercises to benefit the heart. This invention combines a stepper mechanism to simulate stair climbing for purposes of cardiovascular workout.
Most multi-station fitness machines are not built to be collapsible in some form to reduce the projected floor area they occupy when they are not being used. The present invention is designed to be collapsible. This gives the present invention the capability to be placed in a small room where it can interchangeably share floor space with other small furniture. During exercise session, the small furniture can be moved out of the way temporarily allowing the fitness machine to be unfolded and/or extended into the freed space. When the exercise session is over, the machine is retracted and/or folded back for stowage thus freeing up needed space for the furniture.
Most multi-station fitness machines have limited capability for the user to change the positions of the levers to suit his/her physical stature to comfortably perform the various exercises. The present invention has flexibility built into it whereby adjustments in the force application levers and resistance mechanisms can be made with minimal effort to suit the specific needs and physical stature of the user. Short, tall, small or big people can use the machine without being encumbered.
SUMMARY OF THE INVENTION
In the present invention, a fitness machine comprises upper body workout unit, leg curl/extension workout unit, leg press workout unit and cardiovascular workout unit with all the units being structured and combined to form a complete fitness machine to enable three or more users to exercise simultaneously to build and tone various muscles of their bodies.

The design and construction of unit 20 being modular, its components will be described in detail starting from the base module and moving upward. FIG. 2 shows the right side elevation of unit 20. FIGS. 3, 3A, 3B, 3C and 3D show details of the support base module. The support base is comprised of two oppositely disposed parallel horizontal tubes 21 and 23 transversely connected adjacent their distal ends to a third horizontal tube 22 at locations 24 and 25 respectively. Tube 21 has a bushing 21A at its proximal end, a second bushing 21B at its distal end and a pair of parallel transverse through holes 21C adjacent its proximal end. Tube 22 has a pair of parallel transverse through holes 22A centered on its lengthwise center location. Tube 23 has a bushing 23A at its proximal end, a second bushing 23B at its distal end and a pair of parallel transverse through holes 23C and 23D adjacent its proximal and distal ends respectively.
FIGS. 4A, 4B and 4C show the details of the rear support frame module. The rear support is comprised of a pair of oppositely disposed parallel upright tubes 28 and 29 transversely connected adjacent their top ends to a top horizontal tube 30 at locations 32 and 33 respectively. Upright tube 28 has a bushing 28A at its top end, a pair of parallel transverse through holes 28B adjacent its bottom end and a single transverse through hole 28C adjacent its top end in line with the horizontal axis of tube 30. Upright tube 29 has a bushing 29A at its top end, a pair of parallel transverse through holes 29B adjacent its bottom end and a single transverse through hole 29C adjacent its top end in line with hole 28C of upright tube 28. Horizontal tube 30 has a pair of parallel transverse through holes 30A centered on its lengthwise center location.

The multi-party multi-purpose fitness machine 10 has capabilities for over thirty different types of exercises for building and toning various muscles of the body from the neck all the way down to the legs. The upper body workout unit 20 is used to develop the arm muscles, muscles of the neck, upper back, lower back, shoulders and the chest. The leg curl/extension workout unit 80 is used to build and tone the leg muscles specifically the quadriceps, the hamstrings and the muscles lying on the front of the lower legs. Additionally, unit 80 can be used to perform arm curl exercises to strengthen the arm muscles. The leg press unit 100 is used to develop the leg muscles specifically the quadriceps, the calves, the muscles lying on the front of the lower legs and the two muscles that connect part of the lower spine and hip bone to the top of the thigh. In this inventor's humble opinion that the most important exercise is the one that involves the heart. One of the exercises that has been determined to raise heart rate faster and excite the heart the most is stair climbing. The purpose of unit 200 is basically to simulate stair climbing for intense cardiovascular workout benefiting the heart. Additionally, unit 200 is used to develop the leg muscles specifically the quadriceps, the calves, the muscles lying on the front of the lower legs, the two muscles which connect part of the lower spine and hip bone to the top of the thigh and most importantly the gluteus maximus, the muscles of the buttock. For firming up the rear end, unit 200 is as good as one can get.
For all its simplicity, the multi-party multi-purpose fitness machine 10 packs a punch in terms of exercises one can perform on it and the number of users who can use it simultaneously. This fitness machine can accommodate at a minimum three users to exercise on it simultaneously to build and tone various muscles of their bodies. A maximum of five users can work on it simultaneously. The fitness machine has flexibility built into it for users to readily adjust the force application levers and the positions of the resistance mechanisms to suit the specific stature of any user and the type of exercise desired. This fitness machine has built-in stepper for the purpose of performing cardiovascular exercises to benefit the heart. The design of the machine has been simplified to eliminate complexities in manufacturing, set-up and maintenance. One of the benefits of this simplified design is the machine's capability to be collapsible when it is not operational.
In conclusion, there are all types of fitness machines in existence for any type of exercise desired. However, the goal of this invention is not to add one more, but to create a uniquely built affordable and efficient fitness machine that offers the most variety of exercises benefiting the entire human body for the least floor space and headroom requirements and the maximum number of simultaneous users and the least complexity in its ease of use, manufacturability, set-up and maintenance. It is this inventor's humble opinion that the multi-party multi-purpose fitness machine is it.
