1. Field of the Invention
The present invention relates to exercise machines and more particularly pertains to a new exercise device for strengthening of the arms and back.
2. Description of the Prior Art
The use of exercise machines is known in the prior art. U.S. Pat. No. 641,519 describes an exercise device which is mounted on a vertical surface and uses a pulling motion for exercise. Another type of exercise machine is U.S. Pat. No. 5,496,234 which again uses a vertical mounted orientation for a pulling device.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that allows a pulling motion where there person is in a seated position and pulling towards themselves.
The present invention meets the needs presented above by using a wheel mounted on a frame which extends vertically upwards from a base wall.
Still yet another object of the present invention is to provide a new exercise device that, unlike the previous art which is mounted on a wall, is positioned on a floor and may be stored after use.
To this end, the present invention generally comprises a frame having a base wall and a forked member that is attached to and extends upward from an upper side of the base wall. The forked member includes a pair of arms. A wheel is positioned between the arms and is rotatably coupled to the frame. An elastic band is positioned on and extending around a periphery of the wheel. A tension adjuster adjusts rotation of the wheel. The tension adjuster is attached to the frame for adjusting the rotation of the wheel. Pulling on the elastic band provides exercise and rotates the wheel.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A tension adjuster 26 is attached to the frame 12 for adjusting rotation of the wheel 20. The tension adjuster 26 includes a first bracket 28 with a pair of legs 30 and a middle section 32 is attached to ends of the legs 30 such that the first bracket 28 generally has a U-shape. The first bracket 28 is attached to the frame 12 and extends away from the frame 12 such that each of the legs 30 is positioned on an opposite side of the wheel 12. The elastic band 22 is positioned between the middle section 32 and the wheel 22.
A rod 34 extends through and is threadably coupled to the middle section 32. The rod 34 has an inner end 36 extending toward the wheel 20 and an outer end 38. A handle 40 is attached to the outer end 38.
A second bracket 42 is attached to the inner end 36 of the rod 34 such that the second bracket 42 may be selectively moved toward or away from the wheel 20. A pair of stabilizers 44 is attached to the second bracket 42 and extend through elongated slots 46 in the legs 30.
A cylinder 48 is rotatably attached to the second bracket 42 and has an axis of rotation orientated parallel to an axis of rotation of the wheel 20. The cylinder 48 has a concave outer surface 50 in abutment with the elastic band 22. The cylinder 48 may be selectively positioned nearer the wheel 20 for placing tension on the wheel 20.
A first guide member 52 retains the elastic band 22 on the wheel 20 and is attached to an upper end of the forked member 16 such that the first guide member 52 extends over the wheel 20.
A second guide member 54 retains the elastic band 22 on the wheel 20 and is attached to the frame 12. The second guide member 54 includes a pair of rollers 56 each rotatably attached to the frame 12 and positioned generally adjacent to the base wall 14. Each of the rollers 56 is attached to one of the arms 18 and is in abutment with the elastic band 22. The rollers 56 have a rotational axis generally orientated perpendicular to the rotational axis of the wheel 20.
In use, the elastic band 22 is pulled and the wheel 20 rotated to provide exercise. Usually a user will do this sitting down and pull on a slack portion 58 of the band 22 shown in
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
