DETAILED DESCRIPTION

[0014] While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that are embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention. Those of ordinary skill in the art will recognize numerous equivalents to the specific apparatus and methods described herein. Such equivalents are considered to be within the scope of this invention and are covered by the claims.

[0015] In the drawings, not all reference numbers are included in each drawing, for the sake of clarity. In addition, positional terms such as “upper,” “lower,” “side,” “top,” “bottom,” etc. refer to the apparatus when in the orientation shown in the drawing. A person of skill in the art will recognize that the apparatus can assume different orientations when in use.

[0016] Referring to FIGS. 1-6, one embodiment of the adjustable sledgehammer workout apparatus 10 of the present invention may include a handle 12, a pair of supporting brackets 14 connected to an upper portion of the handle 12, and a clamping assembly 16 connected to the supporting brackets 14. The handle 12 may be 3 feet long but may vary in length in other embodiments. The handle 12 may be manufactured out of steel or any other material suitable for supporting the loads applied to the handle 12. The handle 12 may be hollow and may include end caps 18 (FIG. 4).

[0017] The supporting brackets 14 may be welded to the upper portion of the handle 12 and may be rectangular in shape with beveled or rounded edges 20 (FIG. 3). The supporting brackets 14 may also be manufactured out of steel or another suitable material. The supporting brackets 14 may be u-shaped as shown in FIG. 5 or solid blocks of material.

[0018] The clamping assembly 16 (FIG. 3) may include a pair of lower c-shaped portions 22 connected to a pair of upper c-shaped portion 24 using a hinge assembly 26, all of which may be manufactured out of steel or another suitable material. The clamping assembly 16 may be welded to the supporting brackets 14. The lower c-shaped portions 22 may include threaded openings 28 (FIG. 5) for receiving threaded bolts 30 (FIG. 7). The threaded openings 28 may extend through the lower c-shaped portions 22.

[0019] The upper c-shaped portions 24 may be connected together using an elongated, u-shaped support 32, which may be welded to the upper c-shaped portions 24. The upper c-shaped portions 24 may include threaded openings 34 for receiving the threaded bolts 30. The threaded openings 34 may extend through the upper c-shaped portions 24.

[0020] The hinge assembly 26 may include a pair of hinge pins 36 (FIG. 6) disposed in the upper and lower c-shaped portions, 24 and 22, and three hinge arms 38 (FIG. 5) connected to the upper and lower c-shaped portions, 24 and 22, using the hinge pins 36. The upper and lower c-shaped portions, 24 and 22, may include notches 40 and the hinge arms 38 may be disposed in the notches 40. The hinge assembly 26 may allow the upper c-shaped portion 24 to pivot up, back, and down with respect to the lower c-shaped portion 22.

[0021] The apparatus 10 may include different sized rubber pads, 42, 44, and 46, (FIG. 7) which may be wrapped around dumbbells before they are placed in the clamping assembly 16.

[0022] The workout apparatus 10 may be used by removing threaded bolts 30 (which may be hex bolts), lifting the upper c-shaped portion 24 up (FIG. 3), placing a dumbbell in the lower c-shaped portion 22 (optionally wrapping the dumbbell with one or more rubber pads to ensure the dumbbell fits securely in the clamping assembly 16), closing the upper c-shaped portion 24 so that the threaded openings 28 and 34 are aligned, and then securing the upper and lower c-shaped portions, 24 and 22, together using the threaded bolts 30. A user can then exercise by swinging the workout apparatus 10 like a sledgehammer against a large tire.

[0023] The workout apparatus 10 may include any one of a number of different clamping assemblies. For example, as shown in FIGS. 8 and 9, the clamping assembly 16 may be replaced with clamping assembly 48, which is identical to clamping assembly 16 expect that the threaded bolts 30 have been replaced with tightening fasteners 50. In FIGS. 10-13, clamping assembly 16 has been replaced with clamping assembly 52, which may include v-shaped lower portion 54, L-shaped upper portion 56, and multiple jack screw fasteners 58. Lower portion 54 and upper portion 56 may be welded to the upper portion of handle 12. The upper portion of the handle 12 may be modified to include a v-shaped notch 60 for receiving the v-shaped lower portion 54 in one embodiment (FIG. 11). A similar version without v-shaped notch 60 is shown in FIG. 12. The upper portion of handle 12 may also been modified to include smaller v-shaped notch 62 as shown in FIG. 13. The clamping assembly 16 may be replaced with draw clamp 64 as shown in FIG. 14 or toggle clamp 66 as shown in FIG. 15.

[0024] FIGS. 16-19 show a cable pull version of the workout apparatus 10. In this embodiment, the handle 12 includes a rotatable lower portion 68, a cable 70 disposed in the handle 12, a tension rod 72 having one end connected to the cable 70 and an opposite threaded end 74 connected the rotatable lower portion 68. When the rotatable lower portion 68 is rotated in one direction, the tension rod 72 and the cable 70 are pulled in one direction and, when the rotatable lower portion 68 is rotated in an opposite direction, the tension rod 72 and cable 70 are pulled in the opposite direction.

[0025] Thus, although there have been described particular embodiments of the present invention of a new and useful ADJUSTABLE SLEDGEHAMMER WORKOUT APPARATUS, it is not intended that such references be construed as limitations upon the scope of this invention.
