Portable exercise machine

Abstract

A portable exercise machine is provided for rotator cuff exercise. The portable exercise machine includes a flat board having an upper surface and a U-shaped cutout for receiving a torso of a user. A pair of opposing, rotatable arms are affixed to the upper surface of the flat board. The distal end of each arm includes a handle adapted to be grasped by a user and the proximal end of each arm is pivotally coupled to a steel coil. The steel coil provides resistance against the rotation of the distal end of the arms. The steel coil can be removably affixed to an inner connection region or an outer connection region of the flat board. The outer connection region provides resistance for inward movement of the arms and the inner connection region provides resistance for outward movement of the arms.

DETAILED DESCRIPTION OF THE INVENTION

(7) Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the portable exercise machine. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for exercising a user's arms. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

(8) Referring now to FIGS. 1 and 2, there are shown perspective views of the portable exercise machine providing resistance for inward and outward movement of the arms, respectively. The present invention provides an apparatus for exercising, conditioning, and strengthening various hand, wrist, forearm, and rotator cuff muscles. The portable exercise machine 100 comprises a pair of arms 108 that provide resistance when a user rotates the arms in an inward or outward motion. The exercise primarily serves to strengthen the rotator cuff muscles by providing resistance for inward and outward movement. The portable exercise machine 100 comprises a flat board 102 that is substantially rectangular in configuration. The flat board 102 includes a U-shaped cutout 106 that is adapted to receive the torso of a user. The U-shaped cutout 106 is preferably along the bottom edge of flat board 102 and is centrally positioned thereon.

(9) A proximal end 116 of the each arm 108 is pivotally affixed to the upper surface of the flat board 102 on the bottom edge thereof. The arms 108 include an arm pad 118 configured to receive the forearms of a user. Each arm 108 comprises a proximal end 116 and a distal end 110. The distal end 110 includes a handle 112 adapted to be grasped by a user. The proximal end 116 of each arm 108 is coupled to a steel coil 114. The steel coil 114 is a circular coil which has two ends, a first end and a second end. The first end of the steel coil 114 is coupled to the proximal end 116 of the each arm 108 and the second end is removably attached to the flat board 102 via a plurality of fasteners. The steel coil 114 is wound around into a circle several times to provide a desired resistance.

(10) Referring now to FIG. 3, there is shown an overhead view of the portable exercise machine. The distal end 110 of the arms 108 further comprises a roller assembly 126 including a wheel thereon for allowing the arms 108 to roll across the upper surface 104 of the flat board 102. In some embodiments, the flat board 102 further includes a guide track disposed on the upper surface 104 to allow the roller assembly 126 to rotate in a guided path on the upper surface 104.

(11) The upper surface 104 includes an inner connection region 120 and an outer connection region 122, wherein each connection region 120, 122 comprises a plurality of apertures 124. The apertures 124 are adapted to receive the fasteners disposed on the steel coil 114. The steel coil 114 is removably affixed to the upper surface 104 via a plurality of fasteners, such bolts, screws, and nuts, among others. When the steel coil 114 is affixed to the inner connection region 120, the arms 108 provide resistance against outward movement of the arms. When the steel coil 114 is affixed to the outer connection region 122, the arms 108 provide resistance against inward movement of the arms.

(12) Referring now to FIGS. 4 and 5, there are shown the portable exercise machine in use. The flat board 102 is positioned so that the U-shaped cutout 106 is flush against the user's torso. The portable exercise machine 100 may be used while the user is in a seated position with the user's arms placed over the arms 108 on the upper surface 104 the flat board 102 and grasping the handles 112 thereon. In this way, the flat board 102 can rest directly atop the user's lap. In a first position, the arms 108 are biased toward each other so that the handles are pointed toward the center of the flat board 102. In this configuration, the arms 108 provide resistance for outward movement, thereby working the front head of the rotator cuff muscle.

(13) The user can rotate the arms 108 of the device into a second position in which the arms 108 are biased away from each other. In the second position, the steel coil 114 is affixed to the outer connection region 122. The arms 108 are biased away from each other towards the outer edges of the flat board 102. In this configuration, the arms 108 provide resistance for inward movement, thereby working the rear head of the rotator cuff muscle.

(14) It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. 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.

(15) 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.
