BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to physical exercising equipment, and more particularly to physical exercising equipment used for performing different callisthenic exercises.
2. Description of the Related Art
Many individuals prefer doing calisthenics rather than running or walking or working out using a treadmill, an elliptical machine, or a stationary bicycle. Calisthenics are types of exercises comprising a variety of simple, often rhythmical, movements of specific body parts or movements of the entire body against the force of gravity. They typically include push-ups, sit-ups, jumping jacks, and various leg, back and abdominal stretches. They are normally performed when standing upright, when sitting or when laying in a prone position or in a supine position. An important aspect of most callisthenic exercises is that every individual has a unique autonomy, different athletic skills and different medical and health conditions that allow or prevent the performance some calisthenics exercises.
Most individuals have a particular style or technique when performing callisthenic exercises For example, woman usually perform push-ups slowly with their legs bent so their knees touch the ground while men usually perform push-ups quickly with their legs straight so their toes touch the ground. Some individuals prefer performing push-ups with their hands spaced shoulder width apart while others prefer performing push-ups with their hands spaced outside their shoulders.
Handicapped individuals restricted to a wheelchair often benefit from calisthenics exercises. These individuals find it difficult to move back and forth from the wheelchair to the floor. Also, because elevated exercise bars and weight benches are usually fixed objects that are difficult to access when sitting in a wheelchair.
What is needed is a portable device that can be used by individuals to perform different callisthenic exercises and can be used by individuals with different athletic skills, different autonomies, and have different physical and medical conditions.
SUMMARY OF THE INVENTION
An important aspect of the invention disclosed there is the discovery that a device is needed that is adjustable so that different individuals may perform different callisthenic exercises best suited for them. Such a device should be easily adjustable so it may be used by both advanced and beginning exercisers and by handicapped and non-handicapped individuals.
Disclosed is a portable device designed for performing different callisthenic exercises, such as stretching, bending, twisting, pushups, leg lifts, dips, etc. The device allows the exerciser to increase his body movement without using a back support or a neck support, such as a padded board, or when lying on the floor. The device challenges strength training to all extremes using only muscle movement and flexibility of every exercise being performed for every person, along with the development for increasing flexibility of muscle tissues by the stretching movements for the muscle groups being used during the persons exercise fitness training being performed.
The device includes a right frame support and a left frame support linked by an intermediately located fork assembly. The right and left frame supports are slight angled inward so they converge to provide greater stability and support when used. The front sections of the two frame supports are pivotally connected to the fork assembly. In one embodiment, the fork assembly includes a length adjustable upper connector bar and a length adjustable lower connector bar that allows the spacing between the two front sections to be adjusted.
Each frame support includes an upper support bar and a lower support bar. In one embodiment, the upper support bar is curved upward over a straight lower support bar. Each frame support includes a front bar that is pivotally connected to the front fork. The rear sections of the two frame supports are detached from each other thereby allowing them to be selectively spaced apart and form a V-shaped exercise space between the two frame supports. When exercising, the exerciser adjusts the angles of the two frame supports so they may support the exerciser's hands, arms, legs, and feet at a desired position required for the exercise. Sometimes, the frame supports are moved to allow a wheelchair to be positioned in the V-shaped space. When exercising, the exerciser positions himself partially or entirely inside the V-shaped exercise space and uses the two frame supports to support his hands, arms, legs, and the upper and lower torsos. By moving the two rear sections inward or outward, the exerciser can adjust size and shape of the V-shaped exercise space.
Each frame support may include a length adjustable front leg and a length adjustable rear leg that allow the exerciser to selectively lower or raise the front section and rear section respectively.
Attached to upper support bar and the lower bar are optional collars made of soft foam that may be used as hand grips or shoulder protection pads. Also, attached to each frame support is a first handle. In one embodiment, the first handle is L-shaped and can be selectively rotated and locked in a fixed position for a desired exercise. The device may also includes a pair of second handles attached to the two frame supports, a suspended seat, and one or two horizontal bars that selectively attach to the two frame supports and extend across the exercise area.
When performing a callisthenic exercise, the exerciser may stand upright or lay in a supine or prone position. The exerciser may use the suspension seat and positioned himself in a sitting position between the two frame supports. The exerciser may grip the upper curved bars, the lower curved bars, the set of first handles, the set of second handles. When one or both horizontal bars are used, the exerciser may use them as support structures for bending around. After performing a callisthenic exercise, the exerciser can easily adjust the spacing of the front fork assembly, the lengths of the front and rear legs, and the angles of the handles, and remove the suspension seat or horizontal bars to perform the next desired exercise.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
Referring to the accompanying FIGS. 1-12, there is shown a portable device 100 designed for performing different callisthenic exercises, such as stretching, bending, twisting, push ups, leg lifts, dips, etc. More specifically, FIGS. 1-6 is a front perspective view of the portable physical exercise device 100 that includes a rigid, right frame support 102 and a rigid left frame support 102′ connected to an intermediate front fort assembly 150.
Each frame support 102, 102′ includes an upper support bar 110 and a lower support bar 120. The upper support bar 110 is U-shaped and configured to curve upward over the straight lower support bar 120. The upper support bar 110 includes a front tube 116 that connects to the front end of the lower support bar 120.
Extending forward from the upper support bar 110 and the lower support bar 120 is a front extension 111. Each front extension 111 includes upper and lower extension arm 112, 113, respectively, and a vertical arm 114 disposed between the two extension arms 112, 113.
The fork assembly 150 links the two front sections of the frame supports 102, 102′ together. As discussed further below, the fork assembly 150 is adjustable in length and allows each front frame 110 to rotate independently.
The fork assembly 150 includes two outer tubes 151 that are coaxially aligned and extend over the vertical arms 114 on the front extensions 11. Attached to each outer tube 151 are two stubs 157, 167 and 159, 169. A tube 155 and 165 is extended between the stubs 157, 159 and 167, 169, respectively, on the adjoining outer tube tubes 151. The tubes 155, 165 and the stubs 155, 165 may have holes and pins that allow the exerciser to adjust the length of the fork assembly 150. Mounted on each upper support bar 110 is a hinge 162 with a plurality of holes 163 formed therein that receives an upward extending pin 164 with a laterally extending handle 166. The pin 164 extends upward from the outer tube 151 and engages one of the holes 163 as shown FIG. 6.
The rear sections of the two frame supports 102, 102′ are both detached allowing them to be selectively spaced apart and forming a V-shaped exercise space 20 between the two frame supports 102, 102′. When exercising, the exerciser 300 adjusts the angles of the two frame supports 102, 102′ so they may support the exerciser's hands, arms, legs, and feet at a desired position required for a particular exercise. Sometimes, the frame supports 102, 102′ are moved to allow a wheelchair to be positioned in the V-shaped exercise space 20. When exercising, the exerciser 300 positions himself partially or entirely inside the V-shaped exercise space 20 and uses the two frame supports 102, 102′ to support his hands, arms, legs, and the upper and lower torsos. By moving the two rear sections of each frame support 102, 102′ inward or outward, the exerciser 300 can easily adjust size and shape of the V-shaped exercise space 20.
Attached to upper support bar and the lower bar are optional collars 142, 144, respectively, made of soft foam that may be used as hand grips or shoulder protection pads.
Each frame support 102, 102′ includes an optional front adjustable leg 134 and an optional rear adjustable leg 138. In the embodiment shown herein, the upper frame bar 110 is hollow and the leg 116 is hollow thereby allowing the legs 134, 138 to extend. Suitable holes and pins are formed on the legs and on the bar 110 and the leg 116 that allows the exerciser 300 to adjust their lengths and elevate the front and rear sections of the device 100.
As shown in FIGS. 2 and 3, each frame support 102, 102′ is angled inward so the device 100 securely supports the full weight of the exercising 300. Attached to the lower end of each front and rear leg 134, 138 is a pivoting foot pad 132, 136, respectively. Attached or formed on the bottom of each foot pad 132, 136 is an optional layer made of fiction enhancing material, i.e. rubber.
When setup, the two frame supports 102, 102′ are vertically aligned and slightly angled inward to provide support. The device 100 is made of lightweight material and designed to be setup in a semi-collapsed configuration, as shown in FIG. 10, or in one of two fully collapsed configuration as shown in FIGS. 11 and 12.
The device 100 is designed so the exerciser 300 may perform different callisthenic exercises. Representative exercises that may be used with the device are illustrated in FIGS. 13-34. For any exercise, the exerciser 300 may adjust the length of the connector bars so that the front sections of the two frame supports 102, 102′ are sufficiently spaced apart for a desired exercise. Each frame support 102, 102′ can be easily rotated so the rear section of the device 100 is at the desired spacing apart. The angle of each frame support 102, 102′ can be independently adjusted so the rear section of each frame support 102, 102′ may be spaced apart a sufficient distance to accommodate a specific exercise. The lengths of the front and rear legs 134, 138′ may be independently adjusted so each frame support 102. 102′ is disposed at an angle desired for the exercise. When performing a callisthenic exercise, the exerciser 300 may use the upper support bar 110, the lower support bar 120, or the two handles 170. After performing the callisthenic exercise, the exerciser 300 can easily adjust the spacing of the front and rear sections, and the lengths of the front and rear legs 134, 138, respectively, and the angles of the two handles 170 to perform the next desired exercise. In the embodiment shown, the handles 170 attached to each frame support 102, 102′ are L-shaped and may be rotated and locked in different positions for use with different exercises. In one embodiment, a handle plate 186 may be attached to the frame supports 102, 102′, and holes may be formed in the handle plate 186 and pins and are inserted to hold the handle in the desired position on the handle plate 186.
