Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to exercise equipment and more particularly pertains to a new and improved arm exercising apparatus that may be readily and easily secured about a user&#39;s forearm and provided with adjustable plates symmetrically oriented to an overlying gripping bar and an associated user&#39;s hand. 
     2. Description of the Prior Art 
     The use of exercising apparatus is well known in the prior art. As may be appreciated, these devices have normally been of elaborate construction or have been of complex and cumbersome organization that have enjoyed limited acceptance and application by individuals. In this connection, there have been several attempts to develop exercising apparatus which may be easily and efficiently utilized when desired. For example, U.S. Pat. No. 3,759,510 to Jackson, Jr. sets forth a complete exercising body garment that is worn by a user that completely encompasses a user from a user&#39;s feet to head wherein various pockets are positioned about the garment for positioning of weights for exercising various muscles of a user. The Jackson patent is of a relatively complex and cumbersome structure, as is typical of the prior art, and an organization remote to that of the instant invention, but of interest relative to the teaching of an exercising apparatus. 
     U.S. Pat. No. 4,039,183 to Sakurada sets forth a wrist exercising apparatus wherein a wrist securable band has positioned thereto a spring biased handle by which a user may strengthen a desired wrist by pivoting the handle relative to the band against the force of the associated springs. The apparatus to Sakurada is of interest relative to a wrist secured exercising device, but is of a relatively limited applicability as to that of the instant invention. 
     U.S. Pat. No. 4,247,097 to Schwartz teaches the use of an exercising weighted glove that totally encompasses a user&#39;s wrist and hand and included with packets for securement of weights for the purpose of exercise of the individual&#39;s arm and associated body part. The Schwartz patent is of a relatively cumbersome organization and furthermore is resistant to use by individuals due to the enclosed organization and associated heat generated by enclosing a body part during an exercise procedure. 
     U.S. Pat. No. 4,330,120 to Netti sets forth another enclosing exercising device that is securable about a user&#39;s hand, wrist, and forearm wherein variously oriented pockets are secured about the device for insertion of various weights that is consistent with a normal swing motion, as in running or jogging. The Netti patent, while of interest relative to a weighted glove organization, fails to provide the means for exercising a user&#39;s wrist, forearm, and associated shoulder and body parts by means of a properly aligned and oriented adjustable weight organization, as of the instant invention. 
     U.S. Pat. No. 4,337,937 to Lopez sets forth an adjustable wrist exercising device wherein torsional gripping sleeves are adjustable to vary resistance to the gripping sleeves and thereby vary the effort required by a user in twisting the sleeves relative to a central bar. The Lopez patent is of interest merely to note the prior art in setting forth wrist and hand exercising apparatus. 
     U.S. Pat. No. 4,368,883 to Tiktin sets forth a glove provided with a dangling flaccid chain organization whereby various weights may secured, but the glove as opposed to the instant invention will vary the orientation of a suspended weight relative to the glove for securement organization and thereby limit the concentration of exercising effort at a pre-desired orientation relative to a user. 
     As such, it may be appreciated that there is a continuing need for a new and improved weighted exercising apparatus which addresses both the problem of ease of use, adjustability, and predetermined and aligned orientation of weighted means relative to a user&#39;s body part to focus exercise concentration at that part wherein this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of exercising apparatus now present in the prior art, the present invention provides an weighted exercise apparatus wherein the same is readily securable to a user and may be further easily and efficiently adjusted by means of axially aligned and oriented weights relative to a user&#39;s hand and an associated securable grasping bar.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 16 thereof, a new and improved weighted exercise apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the weighted exercise apparatus 10 essentially comprises a platform 11 associated with a forearm strap 12, a grasp bar 20, and an aligned underlying series of weights to said grasp bar. 
     As illustrated in FIG. 2, the platform 11 is formed with an upper surface 15 and a lower surface 14, as illustrated in FIG. 4 for example, wherein forearm strap 12 is captured within a rectangular sleeve 13 integrally secured to lower surface 14. The strap 12 is provided with a first end 16a that may be adhesively secured to strap 13 or sewn thereover to thereby form a loop and secure a strap loop therein. The strap loop cooperates with second end 17 that has formed proximate thereto a hook and loop securement organization formed with hooks 18 about a surface adjacent second end 17 with a series of securement loops formed about a surface adjacent the hook surface 18. Accordingly, as illustrated in FIG. 1, the second end 17 may be passed through the strap loop 16 and thereupon the hooks 18 secured to loops 19 and thereby securely maintained in a selectively releasable manner the apparatus to a user&#39;s forearm. 
     As the forearm strap organization 12 is secured proximate a rear terminal end of the platform 11, a grasp bar 20 is secured proximate a forward terminal end of the platform 11, as illustrated. Reference to FIG. 8 illustrates the grasp bar 20 has formed with a resilient rubber-like covering 21 for the extended use of the apparatus due to the repetitive type nature of an exercising procedure wherein the covering 21 is formed about a rigid core 22 that is preferably formed of a metallic material, but may be in fact formed of any suitable material such as plastics and the like. The grasp bar 20 extends generally transversely of platform 11 and parallel to the sleeve 13 and associated strap 12. A plurality of vertical support stanchions are integrally formed to terminal forward sides of the platform 11 to position the grasp bar 20 at an elevated distance above the upper surface 15. It should also be noted that the forward surface of platform 11 where grasp bar 20 is secured is of a generally wider configuration, as opposed to the rearward portion of the platform 11 upon which the forearm rests due to the need to accommodate a user&#39;s hand and thereby the width of the surface underlying grasp bar 20 is accordingly wider. Illustrated in FIGS. 2, 4, 5, 7, and 8 is a boss 24 orthogonally and integrally formed to the platform 11 and aligned with grasp bar 20 and positioned medially of grasp bar 20&#39;s length, as best illustrated in FIG. 7. This orientation of the boss 24 is significant to properly orient and align the center of gravity of weights positioned about the boss 24. 
     A clamp 25, as illustrated in FIGS. 2, 13, and 14, is formed with a ring 26 and an associated lock handle 27 formed with a threaded end 28 on a distal end of lock handle 27 to cooperate with a threaded radial bore 29 within ring 26 to secure an association of weights between surface 15 and the clamp 25 about boss 24. 
     As illustrated in FIGS. 1, 2, 9, 10, 11, 12, 15, and 16 are the associated weights, as utilized with the instant invention. Essentially, an outer cup-shaped weight 30 is formed with an interior and an axially formed opening to slidingly cooperate with boss 24. Either an individual weight 34, as illustrated in FIG. 11, is utilized and positioned within the interior of the cup-shaped weight 30, as illustrated in FIG. 9, or alternatively a series of weights, such as first weight 31, second weight 32, and third weight 33, are positionable within the interior of cup-shaped weight 30 to provide a greater latitude of adjustment of the amount of weight utilized by an individual. As illustrated in FIG. 16, the series of weights 31 through 33 are completely nestable within the cup-shaped weight 30 and are formed with progressively decreasing heights to position themselves within the interior of the cup-shaped weight 30 and not protrude therefrom. Accordingly, a series of cup-shaped weights 30 through 32 are utilized with a final interior weight 33 of generally cylindrical configuration to fill the remaining void within the second cup-shaped weight 32. It may be understand that an even greater number of cup-shaped weights may be utilized dependent upon the needs of an individual and the series of four weights, as illustrated in FIG. 16 for example, are merely illustrative. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relative to the manner of usage and operation will be provided. 
     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.
