## Title
Exercise apparatus, methods of using, and method of manufacture

## Abstract

A variable resistance-type exerciser has pivotally interconnected arms with a longer pair of padded handle forming ends and a shorter pair of padded handle forming ends. An elastomeric band is interchangeably fitted to the arms through integral slots in each arm forcing the longer handles apart and the shorter handles together. The elastomeric band can easily be replaced or additional bands added to vary the resistance and resulting weight bearing equivalent load of the device. A pin interconnects the arms forming a device that pivots about an axis perpendicular to the plane of the device and in such a fashion as to allow for pushing and/or pulling motions. The exerciser is used by pushing or pulling the longer ends toward one another and/or by pushing or pulling the shorter ends apart. A multitude of exercises results from applying the above described motions to various upper or lower body muscle groups.

## Background
DATA SOURCES
This application claims the benefit of U.S. Provisional Patent Application No. 61/457,637, filed Apr. 14, 2011, which is incorporated by reference herein in its entirety.


TECHNICAL FIELD
This disclosure relates to the use of exercise equipment and, more particularly, to the use of lightweight portable exercise devices, which provide numerous versatile exercises that target a multiplicity of muscle groups within either the upper or lower body.
BACKGROUND ART
The present invention is in the technical field of exercise. More particularly, the present invention is in the technical field of exercise devices. More particularly, the present invention is in the technical field of lightweight, portable exercise devices.
Conventional exercise devices, such as weights including those of the type of bar bells and dumb bells, stationary exercise machines of either weight bearing or other forms of mechanical or other resistance in nature and the like, are typically either immovable or exceedingly difficult to transport. It is difficult to use these devices in a house, office, or facility outside of a traditional gym because they are large and heavy. Moving such devices typically requires several strong persons, or a sturdy wheeled vehicle such as a reinforced wagon or handcart. The difficulties of bringing such a device into a house or office are multiplied when stairs must be climbed. Further, it is not an uncommon desire to afford such exercise devices as portable rendering them capable of transport on a trip or excursion. Devices as those described, which are heavy and bulky in nature, do not lend themselves to the concept of portability and transport for a journey or use outside of the gym.
Further, exercise devices as heretofore described are most often developed to train specific muscle groups requiring a multiplicity of devices to exercise the entire muscular system of the human body. Such devices are dedicated in task to exercising limited muscle groups requiring unique devices to be maintained for the purpose of providing whole body workout routines. Such equipment is not only numerous due to exercise specificity; but, by nature it is bulky and requires significant space for setup and use, rendering them inappropriate to compact, portable use.
It is in the simplicity of this invention that makes it novel. It is lightweight, portable and versatile in its application rendering it ideal for transport and use both in the home, on trips, and at other locations outside of the traditional gym. The uniqueness of the device also renders the need for heavy, dedicated workout devices unnecessary, eliminating the need for multiple, complex workout equipment in the exercise of the whole body including multiple muscle groups.
SUMMARY OF INVENTION
The present invention is an exercise device for users that is compact, lightweight and portable. Current devices are either too complicated to manufacture, too limited in the number and quality of exercises that can be performed with them, or both. This device has been designed to be very simple and cost-effective to manufacture, to be extremely portable and usable by the widest variety of people, from senior citizens to body builders and athletes. This invention allows a person to perform numerous exercises with varying degrees of resistance, is fully self-contained, and extremely lightweight and portable.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of an exercise device of the present invention;
FIG. 2 is a side view of an exercise device of FIG. 1;
FIG. 3 is a section view of the exercise device of FIG. 1 taken along line 3-3 detailing the pivotal joining mechanism.



DETAILED DESCRIPTION OF THE INVENTION
Referring now to the invention in more detail, in FIG. 1 is shown an exercise device 10 comprised of two arms 11 and 12 secured in the center through a slot FIG. 3-36 by pin halves 33 and 34 allowing arms 11 and 12 to pivot about this connection point 13 and in the plane of the two arms. The resulting device configuration being comprised of an upper half of two (2) shorter handles 16a and 16b fitted with padded rubber grips 19a and 19b respectively and a lower half of two (2) longer handles 15a and 15b fitted with padded rubber grips 18a and 18b respectively. A resistance band 14 of a type of an elastomeric or other resistive material is replaceably fitted into the slots 17a and 17b in the arms causing the shorter ends of the arms 16a and 16b to be drawn toward one another, and the longer ends of the arms 15a and 15b to be forced apart from one another.
In more detail, and now referring to the invention of FIG. 2, the exerciser 20 as shown includes two arms 21 and 22 each having a shorter end 26a and 26b and a longer end 25a and 25b. Notably, the shorter ends of the arms 26a and 26b are fitted with padded material 29a and 29b to provide comfortable grips and to add a friction surface to the device. In a similar manner, the longer ends of the arms, 25a and 25b, are also equipped with similar padding 28a and 28b for the same purpose of providing comfort and a friction like surface.
In further detail, the arms 21 and 22, having been joined through the central slot FIGS. 3-36 with a pin comprised of pin halves 33 and 34, can now pivot about this joint 23 freely. A replaceable band of elastic material 24 is fitted in slots 27a and 27b in such a fashion as to cause the band 24 to be placed in tension. The tension in band 24 causes the ends of arms 21 and 22 namely 26a and 26b to be drawn toward one another while at the same time causing the opposite ends of the arms namely 25a and 25b to be forced apart from one another. The tension in band 24, or a plethora of such bands similarly configured, provides the resistance against which exercise is performed. Tension and thus the resistance against which exercise is performed can be controlled by adding multiple bands 24 or by adding bands of varying tension, weight, and alternate materials allowing the device to be used for a variety of exercises and with any number of resistance factors. In an alternative embodiment, one or more replaceable bands of elastic material 24 may be attached to the exercise device 10 through hooks or other suitable methods of attaching the band 24 to the device 10.
In its resting or static state, the device is maintained in a closed configuration by tension in the elastic band FIG. 2-24 resulting in the upper, shorter, more closely spaced arms namely 26a and 26b being forced together and the lower, longer, less closely spaced arms namely 25a and 25b being forced apart. From this configuration and using the resistance within the device caused by the elastic band, results in exercises of a nature where the upper, shorter arms are pulled apart against the resistance or the lower, longer arms are pushed together against the resistance.
The construction details of the invention as shown in the section view of FIG. 3 depict arms 31 and 32 joined by pin halves 33 and 34 through slot 36. This connection forms a frictionless joint about which arms 31 and 32 pivot on bearing sections 35a and 35b. The device provides lateral movement about this pivot point of the joint providing both push and pull resistance exercises. When the exercise device is equipped with a resistance band as described, exercises requiring a pushing or compressing movement can be accomplished using the longer ends of the arms FIGS. 1-15a and 15b while exercises requiring an extension or pulling motion can be accomplished using the shorter ends of the arms FIGS. 1-16a and 16b. 
Alternatively, it will be appreciated that the location of the slots 17a and 17b and the resistance band 14 could be changed to the opposite side of the pin halves 33 and 34 so that the resistance band 14 causes the device 10 to maintain a closed condition with the longer arms 25a and 25b being forced together and the shorter arms 26a and 26b being forced apart. In yet another alternative embodiment, it will be appreciated that the locations of the longer arms 25a and 25b and the shorter arms 26a and 26b could be reversed. In each of these alternative embodiments, exercises are provided of a nature where the upper, shorter arms are pushed together against the resistance and the lower, longer arms are pulled apart against the resistance.
Using the exercise device 10 of the present invention, a user may perform one or more of the following exercises:
the user holds the exerciser with outstretched arms, and presses or pulls either set of the first and second gripping handles either inward or outward respectively against the resistance provided by the elastomeric band;
the user points outstretched arms vertically in an overhead direction and presses or pulls either set of the first and second gripping handles either inward or outward against the resistance provided by the elastomeric band;

the user grips the exerciser and holds it in a manner with the exerciser lateral to one side of the body of the user with one of the interconnected arms being braced against the body in such a manner as to allow the other of the interconnected arms to be pulled toward the body in a lateral motion, against the resistance provided by the elastomeric band;
the user holds the first and second gripping handles at one end of the exerciser that can be laterally expanded outward, holds the exerciser with outstretched arms, and pushes the first and second gripping handles apart against the resistance provided by the elastomeric band;
the user grips the exerciser and holds the exerciser in a manner either in front of, above, or behind the torso or head of the body of the user and pulls the first and second gripping handles apart against the resistance provided by the elastomeric band;
the user sits in a sitting position and places the exerciser on the lap of the user with one of the first and second gripping handles pointing laterally outward toward either side of the body of the user, holds the exerciser with the other of the first and second gripping handles, and bends at the torso in the direction of one of the first and second gripping handles thereby compressing the first and second gripping handles together against the resistance provided by the elastomeric band;
the user sits in a sitting position and places the first and second gripping handles laterally compressed inward between the left and right thighs of the user, holds the exerciser with outstretched arms for stability, and compresses the first and second gripping handles inward together against the resistance provided by the elastomeric band;
the user holds the first and second gripping handles laterally compressed inward, and places the opposite ends of the first and second gripping handles firmly against the outside of the thighs of the user, and presses the first and second gripping handles outward against the resistance provided by the elastomeric band; and/or
the user sits in a sitting position and places the exerciser on the lap of the user with one of the first and second gripping handles pointing laterally outward toward the side of the body, holding one of the first and second gripping handles that can be compressed downward and rotating one of user's arms downward such that the shoulder muscles of the user are stressed against the resistance provided by the elastomeric band.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
