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.

     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.

     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  16   a  and  16   b  fitted with padded rubber grips  19   a  and  19   b  respectively and a lower half of two (2) longer handles  15   a  and  15   b  fitted with padded rubber grips  18   a  and  18   b  respectively. A resistance band  14  of a type of an elastomeric or other resistive material is replaceably fitted into the slots  17   a  and  17   b  in the arms causing the shorter ends of the arms  16   a  and  16   b  to be drawn toward one another, and the longer ends of the arms  15   a  and  15   b  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  26   a  and  26   b  and a longer end  25   a  and  25   b . Notably, the shorter ends of the arms  26   a  and  26   b  are fitted with padded material  29   a  and  29   b  to provide comfortable grips and to add a friction surface to the device. In a similar manner, the longer ends of the arms,  25   a  and  25   b , are also equipped with similar padding  28   a  and  28   b  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  27   a  and  27   b  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  26   a  and  26   b  to be drawn toward one another while at the same time causing the opposite ends of the arms namely  25   a  and  25   b  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  26   a  and  26   b  being forced together and the lower, longer, less closely spaced arms namely  25   a  and  25   b  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  35   a  and  35   b . 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. 1-15   a  and  15   b  while exercises requiring an extension or pulling motion can be accomplished using the shorter ends of the arms  FIGS. 1-16   a  and  16   b.    
     Alternatively, it will be appreciated that the location of the slots  17   a  and  17   b  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  25   a  and  25   b  being forced together and the shorter arms  26   a  and  26   b  being forced apart. In yet another alternative embodiment, it will be appreciated that the locations of the longer arms  25   a  and  25   b  and the shorter arms  26   a  and  26   b  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 points outstretched arms in front with the exerciser held out horizontally, parallel to the floor in front of the user 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;
