The present application claims priority to U.S. provisional application Ser. No. 60/575,676 filed on May 28, 2004.
The present invention relates to exercising devices, and particularly to an adjustable hand grip system adapted for use with treadmills.
Treadmill exercising machines are well known and basically consist of an endless belt mounted in a base. By walking or running on this belt, one may obtain an aerobic level of exercise. Treadmill machines come in wide variety of configurations with most modern models now being powered by electric motors and providing a variety of controls to set the speed and perhaps incline of the belt at a desired position for exercise. Less expensive models have fewer features and may even be manually powered. The general objective of treadmill devices is to provide the cardiopulmonary benefits of walking, jogging or running. The walking, jogging or running exercise on a treadmill works the large gludimous maximus and deltoid muscle groups, thereby providing aerobic level exercise and corresponding cardiovascular benefits.
While it is possible to exercise on a treadmill machine without utilizing hand grips, hand grips are usually provided for exercisers who prefer or require such grips. Perhaps the most common grip position is that of a horizontal crossbar located directly in front of the exerciser toward the forward end of the treadmill as typified by bars shown in Lynch, U.S. Pat. No. 5,000,440, and in Fisher, et al., U.S. Pat. No. 5,110,117 in phantom. A common alternative position is a side grip such as that shown
While the aforementioned grip configurations have proved suitable for most treadmill users, there remain inadequacies for the use of treadmills in cardiac rehabilitation. After open heart surgery, the recovering patients are instructed to engage in light exercise as a part of their cardiac rehabilitation, and treadmill exercise devices are well suited for this purpose. However, patients are instructed to tuck their arms close to their body with hands positioned directly against the frontal lower chest wall directly beneath their pectoral muscles. When utilizing a horizontal crossbar, the exerciser's hands are necessarily rotated to a horizontal position and in the best case, hands extend somewhat forward from the exerciser's abdomen. Obviously, the use of side grips or pivoting grips moves the exerciser's hands even further away from the desired position, and also causes the arms to be moved away from the sides of the body.
Accordingly, it is a general object of the invention to provide a hand grip assembly that may be adapted for use by exercisers engaged in cardiac rehabilitation, or who need or desire aid with stability and balance while exercising.
It is another object of the invention to provide a hand grip assembly suitable for use in cardiac rehabilitation that when not needed for such purpose may be easily moved out of the way so that traditional grip locations are available.
It is yet a further object of the present invention to provide a hand rail that supplies vertical grips that may be positioned immediately forward of the exerciser's lower chest wall and that also provides grips in the location of a horizontal crossbar.
The above recited objects of the invention and others which will become apparent upon a reading of the following specification and claims are achieved by the present invention which provides for two pivotably mounted hand rails that are rotatable into position, such that each hand rail provides both a horizontal section and a vertical section for gripping immediately forward of the exerciser and that may be adjusted vertically to the desired height for a particular individual. When not in use, the hand rails may be pivoted out of position so that the treadmill may be utilized with its ordinary hand rail configuration.
The invention may be described with greater clarity and particularity by reference to the accompanying drawings in which like reference numerals are used to indicate like parts in the various views.
Referring now to the drawings in more detail, a treadmill exercise device 10 is illustrated comprised generally of base 11 in which an endless belt 12 is supported longitudinally and upon which the exerciser 17 jogs or walks. Also shown is a display 15 set at the top of display support 14 extending upward from base 11. The display 15 typically provides user controls to adjust speed and incline of the belt 12 and may also provide visual readouts of elapsed time, estimated caloric consumption, heart rate and other information. The features of treadmills vary widely, and the present invention is not restricted to use on any particular model or features other than as set forth in the claims. Of principal interest in the present invention is the support frame, in the illustrated embodiment of
As better shown in
It will be understood that there are numerous methods that may be utilized to provide mounting brackets on the frame of a treadmill and to pivotably attach a hand rail assembly to such mounting points, and similarly that there are many alternatives for lockingly engaging a hand rail assembly in a selected vertical and rotational position.
Although preferred embodiments of the present invention have been disclosed in detail herein, it will be understood that various substitutions and modifications may be made to the disclosed embodiment described herein without departing from the scope and spirit of the present invention as recited in the appended claims.
