ABSTRACT:
BACKGROUND OF THE INVENTION
There presently exists a great variety of apparatus usable by individuals to perform a plurality of exercises. Although most of the known apparatus is useful for the purposes intended, many of them are heavy, cumbersome, difficult to adjust, and limited in the applications in which they may be used. In addition, many of the known devices which are capable of enabling the user to perform a variety of exercises have a plurality of components which, in many instances, must be substituted for one another or rearranged. In some cases the substitution of some parts for others or the rearrangement of parts requires considerable dismantling and reassembling of parts of the apparatus which not only is technically complex, but also time consuming.
To obtain optimum results from an exercise regimen it is necessary that a program be developed and followed and requires the user to perform specific exercises periodically. However, many persons who wish to obtain the benefits of specific programs cannot do so due to their having to travel or otherwise be away from their homes or local gymnasiums where their exercise apparatus is housed.
A principal object of the invention is to provide exercise apparatus which overcomes or minimizes the foregoing disadvantages of currently available exercise equipment.
SUMMARY OF THE INVENTION
Exercise apparatus constructed in accordance with preferred embodiments of the invention is lightweight, portable, easily assembled and disassembled, and capable of enabling the user to perform a plurality of specific exercises without significant modification or rearrangement of component parts of the apparatus.
The portability of the apparatus enables it easily to be packed and carried in a gym bag or case and its size is such as to enable it to be accommodated in carry-on luggage space provided in aircraft.
The component parts of the invention are so constructed that, with very simple adjustments requiring the use of no tools, the user may perform exercises that require the imposition of resistance in upward, downward, or substantially horizontal directions.
Apparatus constructed in accordance with the invention also enables an exceptionally large range of movement of the user-held actuator while still enabling the components of the apparatus to be sufficiently compact to accommodate portability requirements.
The apparatus is so constructed that the user may perform exercises that require the application of both positive and negative resistances of selected values and wherein a selected resistance value may remain substantially constant over the full range of a selected exercise.
In one embodiment of the apparatus variations in the resistance associated with movements of movable components are compensated for automatically so as to enable the resistance level to be substantially uniform throughout the movements.
