ABSTRACT:
FIELD OF THE INVENTION
This invention is directed to the field of portable exercising devices, more particularly to a personal exercising device that may be readily assembled and disassembled, and placed in a kit or convenient carrying case for easy transport.
BACKGROUND OF THE INVENTION
The present invention relates to a personal and portable exercising device that may be conveniently transported to different sites by the easy disassembly thereof and placed in a carrying case. As is known, various types of exercising devices are popular in today's society. In recent decades, as the awareness of the importance of cardiovascular and muscle training has risen, so too has the demand for increased and improved excercise equipment. While gyms and health clubs typically offer a variety of sophisticated and expensive equipment, such clubs are often undesirable because of distance from the user or high membership fees. And, even those who are members of such a facility do not always have the time or energy to visit the club, even when a workout is desired or needed. Further, the public has become more aware that consistent and intelligently applied exercise can lengthen life span, overcome physical dysfunction and provide other related advantages.
Exercising the muscles of the body to increase the strength, muscle size and fitness of an individual by lifting free weights or by using a system of cables and pulleys to lift weights is one of the types of known portable exercising devices. It was found that free weights were cumbersome, created storage problems, can be noisy, damaging to floors and walls, and are heavy limiting portability and increasing shipping cost. The development of devices that used springs or elastic bands to provide the resistance to muscle contraction eliminated the problems inherent with handling heavy weights, but created new problems and were limited to one point of resistance further limiting versatility in types of exercises capable of being performed.
The prior art, as reflected in the following U.S. patents, illustrate and describe a number or personal or portable exercising devices, namely:
a.) U.S. Pat. No. 5,871,424, to Connor, teaches an exercise apparatus having a clamping means for securing the apparatus to a conventional door, at least one elastic resistance band and a flexible resistance harness. The resistance harness includes a pair of arm slings made of a thin, relatively wide fabric material formed in a closed loop and defining an opening therethrough. The resistance harness further includes a connecting strap made of a thin, relatively narrow fabric material and having opposed ends. The opposed ends of the connecting strap are attached to the pair of arm slings such that the arm slings are connected by the connecting strap. The resistance harness further includes a chest strap made of a thin, relatively narrow fabric material and having opposed ends. The opposed ends of the chest strap are attached to the pair of arm slings opposite the connecting strap. The exercise apparatus is compact and lightweight and thus is convenient for individuals who travel frequently to use, transport and store. In a preferred method of using the exercise apparatus, a user extends the upper arms through the arm slings of the resistance harness and pulls the resistance harness using the abdominal muscles in the direction of the pelvis while bowing the lower back outwardly to extend the resistance band. Thus, the spine is elongated and all of the abdominal muscle groups are contracted without placing undue stress on the muscles in the lower back.
b.) U.S. Pat. No. 5,820,529, to Weintraub, relates to a dual operational exercise resistance device that is usable in the home or fitness center by attachment to a supporting structure. The supporting structure can be a freestanding platform base, a wall, or a door. The device can be utilized to replace the weight stack in a universal gym or any exercise machine. The device can be utilized to provide resistance from more than one point of attachment for standard exercise grips. In addition the resistance provided by the device is easily adjustable, providing the appropriate resistance for the particular muscle group being exercised. The device comprises a base that is configured for attachment to a support or exercise machine, a lever arm member having a peripheral edge being pivotally attached to the base having a pulley on end, two pulleys on opposite ends of the base being pivotally mounted on a horizontal axis within vertically orientated mounted brackets and a pulley being pivotally attached to an intermediate point on the base. One end of the lever arm member is attached to a pivotally mounted pulley to which a portion is engaged by a cable and extends therefrom in two directions for attachment to a grip at two alternate locations. To the other end of the bar attached a resistance mechanism that attaches pivotally to an intermediate point on the base. This structure reduces the resistance force produced by the resistance mechanism as the exerciser approaches full contraction of the muscle group being exercised to insure a completely full contraction is made. The device also compensates for the use of a non-linear resistance mechanism.
c.) U.S. Pat. No. 5,766,118, to Connor, describes an exercise apparatus that includes a clamping means for fixing the apparatus to a vertical surface such as a door or a wall, an elastic resistance band and a resistance harness. In a preferred embodiment, the clamping means includes a lag screw having a hook portion adjacent one end. One end of the resistance band is attached to the hook portion of the lag screw and the other end is attached to the resistance harness. In another preferred embodiment, the exercise apparatus further includes an adjustment means for adjusting the vertical location of the resistance harness relative to the clamping means, and the clamping means includes a U-shaped Bracket. The adjustment means includes a belt having one end attached to the U-shaped bracket, and the free end threaded first through an adjustment buckle and then through a hook attached to one end of the resistance band. The other end of the resistance band is attached to the resistance harness. In a preferred method of using the exercise apparatus, a user extends the upper arms through an opening defined by the resistance harness and rotates the upper body about the pelvis while pulling the resistance harness in the direction of the pelvis using the abdominal muscles to extend the resistance band. In another preferred method, the user pulls on the resistance harness in the direction of the pelvis using the abdominal muscles to extend the resistance band without rotating the upper body about the pelvis. Thus, the spine is elongated and all of the abdominal muscle groups are contracted without placing undue stress on the muscles in the lower back.
d.) U.S. Pat. No. 5,468,205, to McFall et al., discloses an exercise apparatus having a pair of pulley support units mounted on a door by straps which vertically encircle the door. The support units are interconnected by a series of elastic bands, such as bungee cords that run vertical paths between the support units. The ends of the bands or cords are wrapped around pulleys and terminated such that a handle may be attached to each of the cords at either the top unit or the bottom unit. Various exercises are possible with one or two arms or legs by pulling on the cords with the handle. The apparatus is easily mounted or dismounted from any door or other vertically oriented and fixed-in-place partition and is small enough to fold and store in a small carrying case.
e.) U.S. Pat. No. 4,747,594, to Houde, is directed to a portable exercise device for use in a doorway, and includes a base with a pair of arms pivotally connected thereto for rotation between a vertical storage position and a horizontal position in which they engage the sides of the opening. Additionally, adjustable brackets on the outer ends of the arms are provided for centering and se
