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 tubular portion 27 telescopically engages the mounting rod 20. The second tubular portion 28 is connected to the handlebar 4. In one embodiment of the adjustable tube 21, the first tubular portion 27 is hingedly and adjacently connected to the second tubular portion 28 such that the second tubular portion 28 is able to be positioned between the mounting rod 20 and the stationary base 1. The first tubular portion 27 and the second tubular portion 28 allow the adjustable tube 21 to be foldable for storage or transportation by allowing the handlebar 4 to be positioned between the stationary base 1 and the mounting rod 20.
In another embodiment of the adjustable tube 21, the present invention comprises a tension cord 12, as detailed in FIG. 7. The tension cord 12 tethers the first tubular portion 27 to the second tubular portion 28 to prevent the second tubular portion 28 from being disconnected from first tubular portion 27 as the second tubular portion 28 is pulled away from the first tubular portion 27. The tension cord 12 comprises a first cord end 23 and a second cord end 24. The first cord end 23 is internally mounted to the first tubular portion 27. The second cord end 24 is internally mounted to the second tubular portion 28. Thus, the tension cord 12 allows the second tubular portion 28 to be dislodged from the first tubular portion 27 while preventing the second tubular portion 28 from being disconnected from the first tubular portion 27.
In accordance to the preferred embodiment of the present invention, the present invention comprises a pair of handgrips 7.

Still further in accordance to the preferred embodiment of the present invention, the stationary base 1 comprises a first base member 17, a second base member 18, and a mounting bracket 19, as exemplified in FIG. 2. 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.

The elastic resistance mechanism 9 provides tension between the stationary base 1 and the foot-supporting bar 5. The elastic resistance mechanism 9 is mounted to the stationary base 1. The elastic resistance mechanism 9 is selectively tethered to the foot-supporting bar 5. In a more specific embodiment of the present invention, the elastic resistance mechanism 9 is mounted onto the first base member 17, as shown in FIG. 3, FIG. 7, and FIG. 8. As an example of this embodiment, the elastic resistance mechanism 9 is an elastic cord and a hook. The hook is adjacently connected to the first base member 17 opposite to the mounting bracket 19. The elastic cord is selectively tethered between the hook and the foot-supporting bar 5, such that the user is able to add or remove the resistance in accordance to their preference. In some embodiments, the elastic resistance mechanism 9 comprises a pulley. The pulley is mounted onto the second base member 18. The pulley rotatably engages the elastic cord in order to reduce friction and to redirect the direction of force along the elastic cord. As the foot-supporting bar 5 is forced away from the stationary base 1 as the user forces weight onto the mounting rod 20, the elastic cord resists the force from the user's weight in order to engage the user's core abdominal muscles to a greater extent than the user's weight alone.
In another specific embodiment of the elastic resistance mechanism 9, the elastic resistance mechanism 9 is an elastic ring, as shown in FIG. 1, FIG. 2 and FIG. 9. The elastic resistance mechanism 9 is mounted across the second base member 18, such that the elastic ring is oriented parallel to the foot-supporting bar 5. A hook is centrally mounted onto the foot-supporting bar 5 and the hook is oriented towards the stationary base 1. The elastic ring is selectively engaged with the hook such that the user is able to add or subtract resistance in accordance to their preference by tethering the elastic ring to the hook or removing the elastic ring from the hook.
As an additional means of providing resistance to the user, one embodiment of the present invention allows the user to adjust the fulcrum point of the mounting bracket 19 onto the tilting arm 2.
