TECHNICAL FIELD
This invention relates generally to exercise equipment. More specifically this invention relates to portable, collapsing, and adjustable exercise equipment.
BACKGROUND OF THE INVENTION
In the current art exercise equipment comes in various forms. Most typically exercise equipment commonly referred to in the industry as “home gyms” comprise large machines that allow a user to perform a multitude of exercises. Often these home gyms are systems which incorporate a large metal frame and house weight plates, bars, and benches thereupon. A user of a current home gym system engages the home gym by selecting weight or resistance as indicated by a desired exercise and then grasping a bar, handle or sitting upon a seat. The user then performs the desired exercise as needed. These systems are usually expensive, require large spaces to house, and are very heavy and immobile once assembled. In the alternative, athletes must join a gym and pay a monthly membership for the privilege of access to similar exercise equipment. This of course is unfavorable as it incurs ongoing expense, and has limited access to the equipment while in use by another member or when the gym is closed for business.
In the applicant's experience there is a deficiency in the existing and prior art wherein there are no sufficiently lightweight, inexpensive, portable, adjustable and collapsible multi-purpose exercise devices. Further, there is a problem in the current art where there are no dependable and adjustable exercise devices that utilize the user's bodyweight to provide resistance during a workout routine. If there is a device that does so, for example a pull-up bar that attaches to a home door frame, the device is often limited to only a few exercises or only one part of the body.
In the applicant's experience, there is a need for an exercise device which is i) portable, ii) adjustable, iii) collapsible when not in use, iv) relatively inexpensive, v) allows for a multitude of exercises to be performed for every major part of the body, and vi) focuses on exercises which implement the user's bodyweight as resistance. The device of the present invention is believed to accomplish all of the foregoing objectives.
SUMMARY OF THE INVENTION
The present invention provides a new and useful portable adjustable multi-purpose exercise device which is collapsible when not in use, relatively inexpensive, allows for a multitude of exercises to be performed for every major part of the body and focuses on exercises which implement the user's body weight as resistance. This device is believed to be useful in the home setting, whereby the individual user may obtain a full work-out without the need for current home gym systems. A device according to the invention is also believed to be favorable for use in large gym environments, hospital therapy rooms, classes and other fitness-related facilities.
In one of its basic embodiments, the basic invention comprises two support frames which are generally triangular and made from a substantially rigid and weight bearing material such as extruded aluminum with a rectangular cross-section. These support frames resemble isosceles triangles having two sides joined at an apex and a base running below, attached to the sides and running approximately parallel to the ground when the device is assembled. In this embodiment, four receiving grooves are cut into the support frame along the length of each side of the triangle. These support grooves comprise a geometry that allows for the insertion of a grip bar into the groove. The geometry of the groove also includes a narrower notch wherein the threaded male screw end of a knob can be inserted and tightened to affix the grip bar to the frame when in use. The orientation, elevation, and orientation of the grip bar when connected to the support frames is dictated by the exercise sought and periodically adjusted by the user.
In this embodiment, the support frame also has a base receiving groove along the base of the support frames. This base receiving groove exhibits a geometry that is unique and complimentary to a tab on either end of a stabilizer bar. The stabilizer bar is used to firmly hold the support frames in a vertical position when the device is assembled, has a generally flat cross section and is made from similar materials as the support frames. This stabilizer bar is oriented and attached to both support frames at a perpendicular angle. This is accomplished by insertion of the tabs into the base receiving grooves of the support frames. Like the grip bar, the stabilizer bar is rigidly fastened to the support frames by use of knobs. These knobs exhibit a male threaded screw at one end which is complimentary and unique to the female threaded screw channels on the support bar. When assembled the knobs can be sufficiently tightened by the user of the device in order to yield a rigid structure on which to perform exercises.
In this embodiment the exercise grip bar has a generally circular cross section, and has two grips along the length of the bar. The grips are made from a spongy material such as foam rubber. Also, this embodiment features four rubberized feet attached to the underside of the base sides of the support frames. The feet act to cushion the device while in use, protect the floor or surface underneath and also attenuate any shaking or movement when in use.
When the device is in use, the user places the support frames on a flat and stable floor with ample room that allows for performance of varied exercise routines. The user then attaches the stabilizer bar to the support frames of the device by inserting the stabilizer bar tabs into the base receiving grooves of the support frames. The user then firmly and rigidly affixes the stabilizer bar to the support frames by inserting the male threaded screw end of a fastening knob through support frame and into a receiving female threaded screw channel in either end of the stabilizer bar. The user then tightens the knobs completely. Once tightened, the device is considered to be assembled and generally represents a pyramidal prismatic shape, with the support frames oriented vertically and perpendicular from the ground; the stabilizer bar oriented perpendicularly between the support frames and running parallel and flush to the ground.
When in use, the user then elects an exercise and places the exercise grip bar into a series of receiving grooves along the front or back side of the support frames. The user then rigidly affixes the exercise grip bar to the frames by use of threaded knobs.
Once the exercise grip bar is firmly in place, the user performs the exercise as directed. This is usually accomplished by pushing or pulling her body weight against the bar and device for a series of repetitions. One example of an exercise is an inverted row where the user pulls herself up towards the recently affixed exercise grip bar on the assembled device.
Thus the present invention provides a new and useful exercise device which is i) portable, ii) adjustable, iii) collapsible when not in use, iv) relatively inexpensive, v) allows for a multitude of exercises to be performed for every major part of the body, and vi) focuses on exercises which implement the user's bodyweight as resistance. The device of the present invention is believed to accomplish all of the foregoing objectives.
Further features and objectives of the present invention will become apparent form the following detailed description and the accompanying drawings.
