Portable and effective wrist, arm and shoulder exercise device

Description

BACKGROUND

Prior Art

The following is a list of prior art that appears relevant to our application:

Wrist, arm and shoulder exercises comprise a major part of general physical exercise routines. These three parts of human body are involved in activities that are carried out on a daily basis. Weakness in any of these parts directly affects the daily activities of a human body. Many different exercise devices have been designed for one or more of the above muscle groups. Some of the prior art devices are very complex while others are comparatively simple.

Lear invented a cord-winding exercise apparatus for wrist and forearm that requires mounting on a door frame, limiting its utility to indoor use only. Gorczyca invented a wrist and forearm exerciser where a straight handle holds a weight on a rope that is wound on the handle when the handle is rotated. This device though simple and handy has limited potential, being useful for only wrist and forearm. The wrist exerciser invented by Fox, and the wrist and hand exercisers invented by Veillette, and John have the fundamentals and limitations similar to the invention by Gorczyca, mostly useful for wrist and hand exercises.

The invention by Sarich uses a bottle as a weight source in an essentially similar device to exercise the wrist and hand. Moss invented a portable exercise device that claims to be a forearm exerciser and developer with limited use for exercising other parts of the body. The arm exerciser invented by Hoff is claimed to be useful in developing and strengthening wrist and arm muscles, and is designed to duplicate the activity of arm wrestling. Cedro invented a wrist and arm exercise device that has multiple components but is aimed at strengthening and exercising only the wrist and hand. The arm muscle exerciser invented by Lee, with a stand and handle design different from the above, provides the basic utility for exercising the wrist and arm muscles. The foregoing citations of prior art have many similar capabilities and uses. Even though they are mostly designed to be simple, they have the fundamental limitation that their applicability is for wrist, hand and/or arm exercises.

Simple and affordable exercise devices are preferred over complex and more expensive devices. The treadmill invented by Moon, Trulaske and Goldfader, the rowing machine invented by Chung-Ting, and the rowing exercise machine invented by Fan are much more complex and less affordable compared to the various foregoing prior art. Even though these complex exercise devices are meant for more than just the wrist, hand and the arm, their complexity, weight and affordability are considerable disadvantages. Simple but effective exercise devices designed to cover a wider range of muscle groups in the body while being affordable, portable and easy to use have definitive advantages and merits.

SUMMARY

The primary objective of the present invention is to provide a simple, easy to use, but effective and portable wrist, arm and shoulder exercise device that covers a wide range of muscle groups. According to one embodiment, our exercise device comprises a hand cycling crank, at the middle of which is attached a rope that is coupled to a means to carry a load at the other end.

In accordance with another embodiment the means on one end of the rope that carries the load allows adding, removing and switching loads. Another objective is to provide an exercise device that is economical and easy to manufacture.

ADVANTAGES

In accordance with the embodiments of one or more aspects, the advantages claimed herein are: a simple, easy to use, portable and effective exercise device for multiple muscle groups associated with the wrist, arm and shoulder. The device has the capability to strengthen and develop muscles, and in addition reduce excess body weight with prolonged daily use. The broad array of muscle groups this exerciser helps to strengthen and/or develop provides an advantage over prior art in its class. The present invention is designed to be a simple and effective device, that its manufacture is economical. Further features and advantages of one or more aspects will become apparent from the accompanying drawings and ensuing description.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

As illustrated in FIGS. 1A-C the embodiments of our present invention comprise a portable exercise device made up primarily of a hand cycling crank 16, a rope 20 and a weight support member 24. The upper end 22A of rope 20 is inserted into the axle hole 18 of the hand cycling crank 16 (FIGS. 1A-B) to couple it by making thick and strong knot 32 at the terminal part of the rope (FIGS. 1A-B, 2A). The lower end 22B of the rope as shown in FIGS. 1B-C is mounted to the weight support member 24 by making a loop 36 around the middle bar 28. The loop 36 is tightly and securely tied using a metallic tie down sleeve 38 leaving a protruding end 40 out of the sleeve 38 as shown in FIG. 2A. The weight support member 24 is structured to position the middle bar 28 in the middle of its embodiment (FIGS. 1C, 2A). The weight support member 24 that hangs from the rope 34 is loaded with one or more weight discs 42 as needed for exercising, by inserting the terminal part 26 of the weight support member 24 and drawing it through the center aperture 46 as depicted in FIGS. 2A-B. Once loaded, weight disc 42 stays flat on the weight support member 24 and both hang from the attached rope 34 in a near horizontal plane as in FIG. 3. In the configuration depicted in FIGS. 1A, 3 the embodiment of the hand cycling crank 16 is preferably constructed of a non-corrosive, cylindrical, rigid material of sufficient strength and temper to withstand the stresses and strains in the purposes served. The rope 20, 34 used in the embodiments as in FIGS. 1B, 2A, 3 is selected for strength and durability. The embodiment of the weight support member 24 is preferably constructed of a metallic material that is non-corrosive and sufficiently strong (FIGS. 1C, 2A, 3).

The loaded embodiment of our present invention as in FIG. 3 is now assembled for use. The embodiment of the hand cycling crank 16 as in FIGS. 1A, 3 comprises a middle axle 10, two crank arms 12 one on either side at right angles to the axle 10 and parallel to each other, and two terminal handles 14 one on either side at right angles to the crank arms 12 and parallel to each other. In use, the two handles 14 of the loaded hand cycling crank 16 are grasped by both hands with the arms outstretched. The device is hand cycled as shown by arrows 48, keeping the axle 10 generally horizontal (FIG. 3). The said hand cycling causes the rope 34 which is coupled to the axle 10, to wind and form wraps 50 around the axle 10, thereby lifting the weight disc 42 that hangs from the taut rope 34. When the weight disc 42 moves up close to the handle 14, the hand cycling motion is briefly paused to reverse the cycling direction while continuing to keep the arms outstretched, thereby slowly bringing the weight disc 42 downwards and unwrapping the rope from the axle 10. This process is repeated as many times as desired with appropriate load.

In addition to exercising with horizontally outstretched arms, hand cycling can also be carried out with the arms outstretched at 30 or 45 degrees above or below horizontality. Such variations will engage a wider range of muscle groups in the arms and shoulders.
