The present invention is directed to fitness equipment, more particularly to a system designed to help a user stretch and maintain a stretched position without straining.
Stretching, while an important part of fitness, can be very difficult for some individuals. For example, many people have difficulty maintaining a stretched position without straining. The present invention features a stretching assistance system designed to help a user to easily stretch areas including but not limited to the calves, hamstrings, lower back, and groin muscles. The system of the present invention helps a user maintain a static stretch and allows for a quick release if necessary.
The stretching assistance system helps provides mechanical assistance in stretching the hamstrings, lower back, calf muscles, and groin muscles by allowing the user to control the intensity of different stretch positions (e.g., five positions, e.g., toe touch, right leg toe touch, left leg toe touch, spread eagle and butterfly stretch) and “locking” them into place so that the user can relax and quickly release when finished. In some embodiments, the system adjusts for heights between about 3 feet to 6.5 feet. The footrest has a support flap used for some stretches, for example a spread eagle stretch and butterfly groin/lower back stretches. The system can fold to a storage position (e.g., generally flat) for easy storage under a bed or in a closet.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
The present invention features a stretching assistance system. In some embodiments, the stretching assistance system comprises a generally elongated base having a front end and a back end, the base functions as a seat for a user; a generally elongated pivoting platform pivotally attached to the back end of the base via a first hinge, the pivoting platform functions to contact a user's back, the pivoting platform can pivot between multiple positions including a folded position wherein the pivoting platform is folded inwardly and positioned atop the base and generally flush with the base, and an extended position wherein the pivoting platform is at an angle (e.g., 120 degrees) with respect to the base, in the extended position a user can comfortably sit on the base; a footrest assembly disposed atop the base, the footrest assembly comprises a footrest base disposed atop the base at or near the front end of the base and a footrest platform pivotally attached to the footrest base via a footrest hinge, the footrest platform faces the back end of the base and can pivot about the footrest hinge between at least an extended position wherein the footrest hinge extends upwardly and generally perpendicularly from the footrest base and a storage position wherein the footrest platform is pivoted toward the footrest base such that it is atop and generally flush with the footrest base, the footrest assembly functions to support a user's feet when the user is sitting on the base with his back to the pivoting platform; an adjustment means for adjusting a position of the footrest assembly with respect to the front end of the base, the adjustment means functions to allow the stretching assistance system to accommodate users of various heights; a first pulley component disposed in the pivoting platform at or near a top end of the pivoting platform, and a second pulley component disposed in the footrest platform at or near a top end of the footrest platform; a rope having a first end and a second end, the first end of the rope is attached to the footrest assembly, the rope extends from the footrest assembly to the first pulley component and wraps around the first pulley component and further extends to the second pulley component and wraps around the second pulley component, the second end of the rope extends outwardly from the second pulley component; and a handle attached to the second end of the rope; and a locking cleat disposed on the footrest platform.
When the second end of the rope is pulled, the pivoting panel pivots toward the footrest. The locking cleat functions to temporarily hold the rope in a fixed position so that the user does not have to continue to pull on the rope during a stretch. Excess rope can be coiled around handle as it is rotated to keep handle in comfortable position for pulling.
In some embodiments, the stretching assistance system further comprises a first padding material (e.g., foam, rubber, or a combination thereof) disposed on a top surface of the base to provide comfort to the user. In some embodiments, the stretching assistance system further comprises a second padding material (e.g., foam, rubber, or a combination thereof) disposed on an inside surface of the pivoting platform (the inside surface faces the users back) for comfort. In some embodiments, the stretching assistance system further comprises a third padding material (e.g., foam, rubber, or a combination thereof) disposed on the inside surface of the footrest platform (the inside surface faces the users feet).
In some embodiments, the adjustment means comprises a plurality of adjustment holes disposed in the base at and near the front end of the base and hardware temporarily disposed in the footrest assembly and engaged in the adjustment holes. In some embodiments, the handle is a dowel handle for coiling up excess rope. In some embodiments, the stretching assistance system further comprises a side panel pivotally attached to a first side edge of the footrest platform via a side panel hinge to support the footrest platform when the users feet are not touching nor supporting the footrest platform in a vertical position (e.g., in the spread eagle and butterfly stretches).
Referring now to
The system 100 of the present invention comprises a generally flat and elongated base 110 having a top surface, a bottom surface, a front end 115, and a back end 116. The base 110 functions as a seat for a user. In some embodiments, the top surface (or a portion thereof) of the base 110 is covered with a first padding material 118a, for example foam, rubber, the like, or a combination thereof. The first padding material 118a may provide comfort to the user when he/she sits on the base 110.
Pivotally attached to the back end 116 of the base 110 (via a first hinge 120a) is a pivoting platform 120. The pivoting platform 120 may function to provide back support (e.g., see
In some embodiments, the angle 105a is about 120 degrees. In some embodiments, the angle 105a is between about 30 to 60 degrees. In some embodiments, the angle 105a is between about 45 to 90 degrees. In some embodiments, the angle 105a is between about 60 to 90 degrees. In some embodiments, the angle 105a is between about 90 to 120 degrees. In some embodiments, the angle 105a is between about 120 to 150 degrees.
The system 100 further comprises a footrest assembly 130 positioned at or near the front end 115 of the base 110. For example, the footrest assembly 130 comprises a footrest base 130b disposed atop the base 110 at or near the front end 115 of the base 110. The footrest assembly 130 further comprises a footrest platform 130a that is pivotally attached to the footrest base 130b via a footrest hinge 130c. For the purposes of describing orientation, the footrest platform 130a is closer to the back end 116 of the base 110 than is the footrest base 130b and the footrest hinge 130c faces the front end 115 of the base 110. The footrest platform 130b can pivot about the footrest hinge 130c between an extended position (wherein the footrest hinge 130c extends upwardly and generally perpendicularly from the base 100, e.g., when in use) and a storage position wherein the footrest platform 130a is pivoted toward the footrest base 130b such that it is atop (and touching) the footrest base 130b.
The footrest platform 130a may be a generally flat panel, however the footrest platform 130a is not limited to this configuration. The footrest platform 130a provides a platform for a user to place his/her feet (e.g., see
In some embodiments, the position of the footrest assembly 130 can be adjusted. For example, in some embodiments, a plurality of adjustment holes 170 are disposed in the base 110 (e.g., in the top surface at and near the front end 115), wherein the footrest base 130b (and effectively the footrest hinge 130b and footrest platform 130a) can be attached to the adjustment holes 170 (e.g., via hardware 172 such as two sets of bolts, screws, washers and wing nuts). In some embodiments the footrest assembly 130 adjusts along a track disposed on the base 110 (at the front end 115). With the hardware 172 removed, the track allows the footrest assembly 130 to slide forwardly (toward the front end 115 of the base 110) and backwardly (toward the back end 116 of the base) along the track until the appropriate position is achieved for the user. Then, the hardware 172 can be reinstalled to secure the footrest assembly 130 in place. The adjustability of the footrest assembly 130 allows the system 100 to accommodate users of various heights. The present invention is not limited to an adjustment hole system or a track system of adjusting the footrest assembly 130 into different positions.
A first pulley component 140a is disposed in the pivoting platform 120 at or near the front end. A second pulley component 140b is disposed in the footrest platform 130a at or near the top end of the footrest platform 130a. A rope 150 engages the first pulley component 140a and the second pulley component 140b (e.g., the rope 150 connects the two pulley components 140 together). Generally, the rope 150 has a first end 151 that is attached to the footrest platform 130a (e.g., near the second pulley component 140b). From the footrest platform 130a, the rope 150 extends to the first pulley component 140a and wraps around the first pulley component 140a. From the first pulley component 140a, the rope 150 extends to the second pulley component 140b and wraps around the second pulley component 140b. The second end 152 of the rope 150 extends outwardly from the second pulley component 140b (e.g., see
When the second end 152 of the rope 150 is pulled (e.g., via the handle 180), the pivoting panel 120 pivots toward the footrest assembly 130. This movement can help press slightly upon the user's back, helping the user achieve a stretch without having to strain and allows the stretch to be held as long as desired. As the user continues to pull on the handle 180, excess rope can be coiled up on the handle 180 to maintain a comfortable position for the user. When the user releases the rope 150 (for moving the rope upward), the pivoting panel 120 is no longer pulled toward the footrest assembly 130 and the pressure on the user's back is relieved, thereby ending the stretch.
A locking cleat 190 is disposed on the footrest platform 130a, for example below the second pulley component 140b (e.g., see
In some embodiments, a side panel 160 is pivotally attached to a first side edge of the footrest platform 130a (e.g., via a side panel hinge 160a). The side panel 160 functions to support the footrest platform 130a in a generally vertical position. For example, the side panel 160 may be used for stretches including but not limited to a spread eagle stretch and butterfly stretch (e.g., when the user's feet are not in contact with the footrest platform 130a to support it vertically). Generally, the footrest assembly 130 must be in a vertical position for the locking cleat 190 to function properly.
The system 100 of the present invention may be constructed in a variety of sizes. For example, in some embodiments, the base 110 is about 54.5 inches in length as measured from the front end 115 to the back end 116. In some embodiments, the base 110 is between about 50 to 60 inches in length as measured from the front end 115 to the back end 116. In some embodiments, the base 110 is between about 60 to 70 inches in length as measured from the front end 115 to the back end 116. In some embodiments, the base 110 is more than about 70 inches in length. In some embodiments, the pivoting platform 120 is about 41.5 inches in length as measured from the top end to the bottom end. In some embodiments, the pivoting platform 120 is between about 40 to 50 inches in length as measured from the front end to the back end. In some embodiments, the pivoting platform 120 is between about 50 to 60 inches in length as measured from the front end to the back end. In some embodiments, the pivoting platform 120 is more than about 60 inches in length. The present invention is not limited to the aforementioned dimensions.
As used herein, the term “about” refers to plus or minus 10% of the referenced number. For example, an embodiment wherein the base 110 is about 54 inches in length includes a base 110 that is between 48.6 and 59.4 inches in length.
