Description

BRIEF DESCRIPTION OF THE FIGURES

(1) The detailed description of some embodiments of the invention will be made below with reference to the accompanying figures, wherein the figures disclose one or more embodiments of the present invention.

(2) FIG. 1 depicts a top perspective view of certain embodiments of the exercise apparatus;

(3) FIG. 2 depicts a bottom perspective view of certain embodiments of the exercise apparatus;

(4) FIG. 3 depicts an exploded view of certain embodiments of the exercise apparatus; and

(5) FIG. 4 depicts a section view of certain embodiments of the exercise apparatus taken along line 4-4 in FIG. 1.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

(6) As depicted in FIGS. 1-3, the exercise apparatus is a portable tool configured for use by a user to perform a variety of exercises. The exercise apparatus is configured to rock laterally on a surface such as the ground to enable the user to perform the variety of exercises in variable positions. This helps the user to improve strength and endurance in different muscle groups including, but not limited to, the chest, shoulders, abs, core and stability muscles. The variety of exercises performed using the exercise apparatus include push-ups, planks, and the like. In certain embodiments, the exercise apparatus is used to perform other exercises such as curls or overhead presses. It shall be appreciated that the exercise apparatus has a weight of approximately 15 lbs and is configured to support a user with a weight of up to approximately 400 lbs.

(7) In certain embodiments, the exercise apparatus generally comprises a pair of side plates 10 oriented generally parallel to each other and coupled together by rods 20 and fasteners 26. The exercise apparatus preferably is made from aluminum. However, alternative metals or other materials known in the field may be used instead.

(8) Each side plate 10 comprises upper concave surface 28, lower convex surface 30, lower fins 32 and a plurality of holes. Each hole in side plate 10 is formed by countersunk hole 16 and slot 14. In a preferred embodiment, each side plate 10 comprises approximate dimensions of a 8 height, 24 length and thickness. However, side plate 10 may have alternative dimensions.

(9) The center of lower convex surface 30 comprises rocker surface 18, which is configured to contact the ground (not shown) and permit lateral rocking movement of side plate 10 on the ground. Lower fins 32 extend from opposing ends of the lower surface of side plate 10 toward the ground. Each lower fin 32 is configured to contact the ground upon continued lateral rocking of side plate 10 in a particular direction. This limits the range of lateral rocking movement permitted by side plate 10. In one embodiment, the entire outer edge of side plate 10 comprises beveled edge 12.

(10) The pair of side plates 10 are oriented generally parallel to each other to align corresponding slots 14 and countersunk holes 16 of both side plates 10 together. As depicted in FIGS. 3-4, the ends of each rod 20 are disposed in slots 14 of side plates 10. For each side plate 10, fastener 20 is inserted within countersunk hole 16 of side plate 10 and threaded hole 22 of rod 20. This secures the end of rod 20 to side plate 10. Fastener 20 is preferably a stainless steel screw that comprises a head portion that rests against countersunk hole 16 of side plate 10. This permits each rod 20 to be securely fastened to both side plates 10. In one embodiment, fastener 20 is a screw that comprises approximate dimensions of 1 in length and in diameter.

(11) In one embodiment, each rod 20 comprises knurled outer surface 24 that enhances grip between the user's hand and rod 20. In a preferred embodiment, each rod 20 comprises an approximate length of 7 and diameter of 1. Although the figures depict six rods 20 coupled to side plates 10, it shall be appreciated that any alternative number of rods 20 may be used instead.

(12) In operation, the user disposes the exercise apparatus on the ground so that rocker surfaces 18 of side plates 10 contact the ground. The user grabs any number of rods 20 to rock the exercise apparatus 10 laterally on the ground to perform exercises such as push-ups, planks, or other movements. The user can grab different rods 20 and rock the exercise apparatus to a desired position to vary the engagement of muscles used when performing the exercises. If the user grabs any one of the outer rods 20, the corresponding lower fins 32 of side plates 10 are configured to contact the ground to limit lateral rocking of the exercise apparatus. This prevents the user's knuckles or hand from contacting the ground, thereby enhancing user safety. In an alternative embodiment, the user can perform alternative movements with the exercise apparatus such as arm curls or overhead presses.

(13) It shall be appreciated that the components of the exercise apparatus described in several embodiments herein may comprise any alternative known materials in the field and be of any color, size and/or dimensions. It shall be appreciated that the components of the exercise apparatus described herein may be manufactured and assembled using any known techniques in the field.

(14) Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
