Description

CLAIM OF PRIORITY

This patent application claims priority under 35 USC 119 (e) (1) from U.S. Provisional Patent Application Ser. No. 62/129,704 filed Mar. 6, 2015, of common inventorship herewith entitled, “Pull Up 360,” which is incorporated herein by reference as though the same were set forth in its entirety.

FIELD OF THE INVENTION

The present invention pertains to the field of exercise equipment, and more specifically to the field of pull up devices.

BACKGROUND OF THE INVENTION

Being physically active is one of the most effective tools in increasing one's health of mind, body and spirit. Reducing risk of heart disease and stroke, physical activity also helps to lower or control other risk factors such as high blood pressure, high blood cholesterol, excess body weight and diabetes. A regular exercise regimen helps an individual look and feel better, become stronger and more flexible, possess more energy, and reduce stress and tension.
More than an approximated five billion dollars is spent on exercise equipment each year. Exercise and fitness are a big business and a major concern to a great many people. Exercise equipment ranges from stair climbing machines and elliptical trainers to rowing machines, free weights, cable guided weight training machines, treadmills and stationary bicycles. The biggest difference between various machines and various forms of training equipment has far less to do with the configuration of the equipment than with how often and how effectively that piece of equipment is used.
If the equipment is too complicated or takes too long to set up and break down, the exerciser is less likely to use it for very long. Some of the most effective fitness products are the simplest ones. An essential and effective exercise, when performed consistently, is the simple pull up. Many-exercisers equip a door frame in their home with an extendable tensioning pull up bar.
The prior art has put forth several designs for pull up devices. Among these are:
U.S. Pat. No. 7,540,831 to Stephen G. Hauser, Mark B. Friedman and Alden M. Mills describes an exercise assembly for performing a wide array of exercises including pull ups and chin ups. The exercise assembly includes a bar connected between rotatable swing arm assemblies. The swing arm assemblies extend along vertical faces of a frame and are adapted to rotate the bar from one position between the vertical faces to another position. The exercise assembly includes at least one handle assembly removably grasping the central bar and having a handle adapted to rotate approximately three hundred sixty degrees during exercise.
U.S. Pat. No. 7,066,866 to Mitch T. Mobley describes a chin up bar assembly with a cross bar and a pair of handles slidably mounted on the cross bar. The handles are pivotally mounted for movement between locked and unlocked positions. When a user hangs from the handles, the handles automatically pivot to the locked position to frictionally engage the cross bar and prevent sliding movement of the handles along the cross bar. The handles also are swiveled during use to exercise different muscles in the user's arms, chest and back.
U.S. Pat. No. 5,776,033 to William R. Brown describes a removable chin up bar arrangement that includes spaced body members situated at opposite ends of a chin up bar extending there between, the bar being rotatable with respect to the body members. Opposed pincher members are swingably attached to each of the body members and are adapted to extend about and hang the body members and the chin up bar from an overhead support such as the framing extending about an interior doorway. A gear tooth lock mechanism extends between the ends of the chin up bar and each of the pincher members. The lock mechanism moves the pincher members in unison toward each other and causes the chin up bar to rotate in a first direction. Upon rotation of the bar in the opposite direction, the pincher members open away from each other, permitting removal of the chin up bar arrangement from the doorway.
None of these prior art references describe the present invention.
