ABSTRACT:
BACKGROUND OF THE INVENTION
There are many varied complex exercise units shown in the patent literature indicating there is a perceived need. The objectives of the subject invention include:
a light weight unit
a unit that may be easily carried in a briefcase or suitcase
a unit that may be easily assembled
a unit that may be placed in various positions or shapes and will stay in said position or shape.
a unit particularly suited for arm, wrist and shoulder muscle and joint rehabilitation.
The major components in this invention are essentially hollow dumbbell plastic shapes with one male end and one female that with considerable force may be snapped together to make a flexible joints so that a series snapped together may be bent or shaped using the force necessary to move each joint. With a handle connected on either end of a one to two foot series of these dumbbell plastic shapes the resistance to movement of the handles is sufficient to give a reasonable work out in a few minutes. Depending upon the use smaller diameter or fewer of the dumbell shaped connectors may be used. Plastic shapes manufactured by LOC-LINE® are suitable for this use.
SUMMARY OF THE INVENTION
The invention includes three somewhat different embodiments of an exercise unit formed with hollow plastic dumbbell shaped components that have a male end and a female end with the female end being sized to forcibly snap over a male end of a separate connector. A group or series of these connectors may be forcibly snapped together and fastened at each end to a handle that may be straight or curved. A one to two foot series of the dumbbell connectors or units has sufficient resistance to movement that a one to two foot segment may be twisted and curled and bent to give a reasonable upper body exercise in a few minutes.
