RELATED APPLICATIONSThis application claims the benefit of US Provisional Patent Application 61309792 filed on Mar. 2, 2010.
BACKGROUND OF THE INVENTIONThe present invention generally relates to weightlifting and training equipment and methods and, more particularly, to machines and methods for enhancing gluteus muscle groups.
Training of athletes may include certain exercises performed in a weight room or workout room. In some instances, specialized machines may be provided to allow athletes to develop and enhance particular muscle groups. One particularly important muscle group is the gluteus group. However, most athletic training rooms do not have machines which may be used to specifically develop and enhance gluteus muscles.
As can be seen, there is a need for an effective machine-oriented training system for developing and enhancing gluteus muscles.
SUMMARY OF THE INVENTIONIn one aspect of the present invention, weightlifting apparatus for use by a person in a standing position to exercise gluteus muscles may comprise a pivoting exercise assembly configured to be positioned at hip level of the person and to be pivoted by a leg of the person; a shoulder brace assembly is configured to provide constraint against a shoulder of the person; and chest brace assembly is configured to provide constraint against a chest of the person.
In another aspect of the present invention, a weightlifting apparatus may comprise weights; a pivoting exercise assembly; a cable interconnecting the weights and the pivoting exercise assembly; and a force-equalizing crescent attached to the pivoting exercise assembly, wherein a portion of the cable passes over the force-equalizing crescent so that force applied to the pivoting exercise assembly by the weights is equalized as the pivoting exercise assembly is pivoted.
In still another aspect of the present invention, a method for exercising gluteus muscles may comprise the steps of bracing a shoulder of an exercising person against a shoulder brace assembly; raising a knee of the exercising person to hip level; placing the knee over a pad of a pivoting exercise assembly; pushing the pad downwardly against resistance of weights attached to the pivoting exercise assembly; and continuing downward pushing until a leg of the exercising person is straight and is extended behind the person.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is perspective view of a weightlifting machine in accordance with an embodiment of the invention;
FIG. 2 is an elevation view of a pivoting exercise assembly of the machine ofFIG. 1 in accordance with an embodiment of the invention;
FIGS. 3 and 4 are side views of a person using the machine ofFIG. 1; and
FIGS. 5 and 6 are rear views of a person using the machine ofFIG. 1.
DETAILED DESCRIPTION OF THE INVENTIONThe following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Various inventive features are described below that can each be used independently of one another or in combination with other features.
Broadly, embodiments of the present invention generally provide an exercise machine in which a user may exercise gluteus muscles while remaining in an erect standing position.
Referring now to the Figures, an exemplary embodiment of a gluteus-isolatingweightlifting machine10 may comprise aframe12,hand grips13, aweight stack14,variable weight adjustments15,guide bars16, apulley18, acable20, ashoulder brace assembly22, anadjustment24 for theassembly22,shoulder braces25, achest brace assembly26, anadjustment28 for theassembly26,chest support pads30 for theassembly26, apivoting exercise assembly32, anadjustment34 for theassembly32,pads36 for theassembly32, a force-equalizing crescent38 and apivot40.
In operation, a user may adjust weights and positions of components of the machine as desired and then approach either a left side or a right side of themachine10. Upon approaching the left side, for example, the user may perform motions as illustrated inFIGS. 3 and 4. The user's right leg may be placed over thepad36 of theassembly32. The user may grasp one of thehand grips13 with his or her left hand. The user's right shoulder may be positioned against theshoulder brace assembly22 and ahand grip42 may be grasped with the user's right hand. The user may then press downwardly with his or her right leg to force thepad36 to move on an ark-like path from a relaxed-starting position shown inFIG. 3 to an extended- force-exertion position shown inFIG. 4. As thepivoting exercise assembly32 pivots about thepivot40, a portion of thecable20 may engage with the crescent38. Interaction between thecable20 and the crescent38 may result in equalization of force applied to thepad36 by theweights14 as the pad moves though its ark motion.
Referring now toFIGS. 5 and 6 it may be seem that the user may exercise his or her left leg by entering the right side of the machine using motions corresponding to those described above.
The machine may be provided with various adjustment features so that it may be properly fitted to the size of a user. For example, a starting location of thepad36 of thepivoting exercise assembly32 may be positioned at a hip height of the user so that the user's hamstring may transfer resistance to the user's gluteus muscles. Also, positioning of theshoulder brace assembly22 and thechest brace assembly26 may be adjusted to provide a stable working position for the user.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
