Portable Inversion Apparatus
A portable support system that utilizes a doorway frame to allow a person to perform various inversion exercises without any modification or marring to the doorway frame and also without the use of gravity boots (ankle device U.S. Pat. No. 3,380,447 granted to Martin). Previous patented door frame support systems (U.S. Pat. No. 3,738,650 granted to Ossenkop et al, and U.S. Pat. No. 4,458,894 granted to Dudley) have required modifications to the door frame, such as mounting brackets screwed into the frame. The person also has to possess gravity boots (ankle device U.S. Pat. No. 3,380,447 granted to Martin) in order to perform inverted exercises. This invention eliminates both of these problems.
1. Field of the Invention This invention relates to inversion exercise support bar assemblies and more particularly to a portable support bar assembly for mounting onto a door frame.
2. Description of the Prior Art The use of a door frame has become very popular with exercise equipment due to the fact that most everybody has access to a door. Prior inversion devices such as U.S. Pat. No. 3,738,650 and No. 4,458,894 have required the use of mounting brackets that have to be screwed into the door frame. These prior devices also require the use of an ankle device U.S. Pat. No. 3,380,447. These two problems needed to be eliminated for a greater appeal to the general population. There is a demand for an invention that can be installed onto a door frame with out any modifications which would allow the user to perform inverted exercises without the use of ankle supports.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a portable support structure that allows a person to perform various inversion exercises without the use of gravity boots (ankle device patent U.S. Pat. No. 3,380,447 granted to Martin).
It is a further object that the invention can be mounted without any modification performed to the doorway frame.
It is a further object that the invention can be dismantled and re-assembled without the use of any tools.
It is a further object that the invention can be dismantled into smaller, portable parts for easier transportation of the device.
It is a further object that the invention causes no damage or marring to the doorway frame.
It is a further object that the invention has separate leg pads and hand pads which allows the person to be able to get into an inverted position.
It is a further object that the invention provides a place to perform various upright exercises also, such as a pull-up.
It is a further object that the invention provides a safe, user-friendly, and economical to manufacture structure a person could use on a daily basis.
These and other objects and advantages with become present after having read the following detailed description and diagrams.
A 6 inch long, ¾ inch pipe (6) can be screwed onto the end of the ¾ inch, 90 degree pipe (2) which is for the user's hands to pull up their lower body and place their legs into the pads (3). The 6 inch long, ¾ inch pipe (6) can be removed when the person is performing pull-ups to avoid interference.
Two, 7 inch long, ¾ inch pipes (12) are screwed into the ¾ inch coupling (10). A 7 inch long, 3 inch diameter foam tube (3) is placed over the 7 inch long, ¾ inch pipe (12).
Every piece of bare metal is covered with a vinyl, rubber tubing to prevent damage or marring of the doorway frame. This vinyl coving protects the person's hands and legs, as well as provides a gripping surface.
After use, the user can remove the invention from the doorway frame.
Although the invention has been described and diagramed in the current preferred embodiment, it should be understood that certain alterations and modifications will become apparent to such individuals skilled in the art. It is intended that the description and diagrams be left open to include certain alterations and modifications.
Claims
