DETAIL DESCRIPTIONS OF THE INVENTION
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention is an abdominal strengthening apparatus. The present invention allows a user to properly perform crunches from a seated position and enhances the strengthening effect of core abdominal muscles through resistance. The core abdominal muscles targeted through the use of the present invention are the upper abdominal muscles, lower abdominal muscles, and oblique muscles.
In accordance to FIG. 1, the present invention comprises a stationary base 1, a tilting arm 2, a supporting member 3, a handlebar 4, and a foot-supporting bar 5. The stationary base 1 supports the present invention on a level ground or floor surface. The tilting arm 2 is pivotably connected to the stationary base 1. The pivotable connection is a fulcrum in order to allow the tilting arm 2 to move as a lever above the stationary base 1 during implementation of the present invention. The supporting member 3 allows the user to use their arms and shoulders to transfer force from the handlebar 4 to the tilting arm 2. The tilting arm 2 lifts the user's legs, therefore forcing the user's upper abdominal muscles and lower abdominal muscles to be engaged. The supporting member 3
comprises a mounting rod 20 and an adjustable tube 21. The mounting rod 20 connects the handlebar 4 to the tilting arm 2 through the adjustable tube 21. The mounting rod 20 is pivotably connected to the tilting arm 2 such that the orientation of the mounting rod 20 is maintained as the tilting arm 2 is depressed local to the mounting rod 20.
The adjustable tube 21 allows the user to change the length of the supporting member 3 to accommodate the height of the user. The adjustable tube 21 is telescopically engaged with the mounting rod 20 such that the user is able to adjust the length of the supporting member 3 between discrete heights. The adjustable tube 21 is positioned opposite to the tilting arm 2, along the mounting rod 20, such that the handlebar 4 is able to be conveniently accessed by the user. The handlebar 4 is adjacently connected to the adjustable tube 21 in order to allow the user to grasp the present invention and make use
of the user's own body weight to provide a downward force on the supporting member 3. The handlebar 4 is positioned opposite to the tilting arm 2 along the adjustable tube 21 in order to transfer the downward force along the supporting member 3. The foot-supporting bar 5 supports the user's feet during implementation of the present invention. The foot- supporting bar 5 is perpendicularly and adjacently connected to the tilting arm 2. The mounting rod 20 and the foot-supporting bar 5 are positioned opposite to each other along the tilting arm 2. As the downward force from the user is placed on the supporting member 3, the tilting arm 2 rotates about the pivotable connection with the stationary base 1 in order to simultaneously raise the foot-supporting bar 5. Thus, through the downward force from the user's weight, the user's knees are forced towards the user's chest while the user's chest is motioned towards the user's knees, engaging the user in a abdominal crunching motion to engage the user's core muscles.
In one embodiment of the present invention, the present invention comprises a rotation mechanism 6, as shown in FIG. 2. The rotation mechanism 6 allows the handlebar 4 to be rotated about the mounting rod 20, such that the user is able to engage the oblique muscles effectively by rotating the user's torso during the abdominal crunching motion. The rotation mechanism 6 is mechanically integrated along the adjustable tube 21. The rotation mechanism 6 is positioned between the mounting rod 20 and the handlebar 4. A rotation axis 22 of the rotation mechanism 6 is collinear to the mounting rod 20. As the user grasps the handlebar 4 and presents the downward force onto the supporting member 3, the user is able to rotate the user's torso from side to side in order to engage the oblique muscles during the abdominal crunching motion, strengthening the oblique muscles.
In another embodiment of the present invention, the present invention comprises a rotation mechanism 6, as shown in FIG. 9. The rotation mechanism 6 allows the supporting member 3 to be rotated, such that the user is able to engage the oblique muscles effectively by rotating the user's torso during the abdominal crunching motion. The mounting rod 20 is pivotably connected to the tilting arm 2 through the rotation mechanism 6. The rotation mechanism 6 is positioned opposite to the adjustable tube along the mounting rod. A rotation axis 22 of the rotation mechanism 6 is collinear to the mounting rod 20. As the user grasps the handlebar 4 and presents the downward force
onto the supporting member 3, the user is able to rotate the user's torso from side to side in order to engage the oblique muscles during the abdominal crunching motion, strengthening the oblique muscles as the supporting member 3 rotates along with the user's motion.
In another embodiment of the present invention, the adjustable tube 21 comprises a first tubular portion 27 and a second tubular portion 28, as shown in FIG. 3, FIG. 4, FIG. 7, and FIG. 8.

The first base member 17 and the second base member 18 provide structural support for the present invention. The mounting bracket 19 supports the tilting arm 2. In accordance to FIG. 3, the first base member 17 is perpendicularly connected to the second base member 18. The second base member 18 is terminally positioned to the first base member 17, such that the first base member 17 and the second base member 18 form a stable base for the present invention. The mounting bracket 19 is centrally connected along the first base member 17. The tilting arm 2 is pivotably connected to the mounting bracket 19, such that the mounting rod 20 is able to translate towards or away from the stationary base 1 in order to allow the user to perform sitting crunches. The tilting arm 2 is positioned coplanar to the first base member 17 such that the tilting arm 2 is positioned above the first base member 17. The tilting arm 2 is connected to the mounting bracket 19 between the foot-supporting bar 5 and the mounting bracket 19, such that the mounting bracket 19 is a fulcrum for the tilting arm 2. In one embodiment of the mounting bracket 19, the mounting bracket 19 is permanently connected to the first base member 17, as shown in FIG. 3 and FIG. 5. The mounting bracket 19 is welded onto the first base member 17 in order to retain the connection between the mounting bracket 19 and the first base member 17.
In accordance to FIG. 8 and FIG. 9, another embodiment of the mounting bracket
19 is removably connected to the first base member 17. The removable connection
between the mounting bracket 19 and the first base member 17 allows for the stationary base 1 to be disassembled and stored more conveniently. The configuration also allows the stationary base 1 to be modular such that the mounting bracket 19 is able to be replaced if the mounting bracket 19 were to fracture or otherwise inoperable. The mounting bracket 19 comprises a first bracket member, a second bracket member. The first bracket member engages the second bracket member about the first base member 17.
