Claims
- 1. A portable abdominal muscles and hip fitness exercise device adapted to be positioned during use on a conventional chair support, while being temporarily anchored thereto by the weight of a user seated upon the chair-seating component of the device, comprising:(a) a generally rectangular rigid frame having a first and a second transverse members, with the frame adapted to be positioned firmly upon planar element of a conventional chair support with the second member axially mounted so as to permit axial rotation; (b) a generally planar seating means sized to overlie the rectangular frame, being secured along its rearward edge to the rearward second transverse member, and secured along its forward edge to the forward first transverse member of the rigid frame; (c) a pair of spaced-apart, elongate handles anchored at the inner longitudinal ends thereof, conjoined to the longitudinal ends of the second transverse member of the rigid frame, forming rearward corners with such handles projecting forwardly at an angle relative to the rigid frame; (d) a third transverse member bridging the space between the paired elongate handles and being positioned therebetween, being spaced apart from and below the second transverse member, and being journal-mounted so as to permit the axial rotation thereof; (e) a single L-shaped, lever arm secured pivotally at the one proximal elongate segment thereof to one longitudinal end of the third member, with the lever arm having its distal longitudinal segment aligned both transversely and horizontally, and spaced apart substantially from and above the level of the associated underlying seating means; and, (f) a tensioning means positioned under the seating means and being anchored thereto, which tensioning means is operatively associated with the proximal elongate segment of the single transverse lever arm, with such tensioning means being adapted to provide a variable resistance to the upward motion of the transversely positioned distal segment of the lever arm, the arcuate motion of which is induced by a drawing in, thigh action of the device-seated user.
- 2. The device of claim 1 wherein the tensioning means comprises at least one pair of longitudinally-aligned tensioning bands spaced apart, and located so as to operatively linked the tensioning means to the transverse third member, thus being adapted to provide a counterforce to the rotation being induced in the third member by its functionally associated lever arm.
- 3. The tensioning means of claim 2 wherein the rigging of the tensioning bands further comprises a moment arm anchored to the third transverse member and moving therewith, and an opposing detent means for interruptibly securing the first pair of longitudinal ends to an anchor point located on the rigid frame.
- 4. The device of claim 1 wherein at least an added first pair of tensioning bands are disposed between an anchoring point on the rigid frame and a first retention point on the moment arm so as to provide a first increased minimal level of counterforce to the user-induced rotation of the third transverse member.
- 5. The device of claim 4 wherein the moment arm comprises a rigid plate secured along one edge thereof, to the rotatable third member, also having peripheral slots adapted to engage the paired longitudinal ends of a third or higher number of tensioning bands and arrayed parallel to the first pair of bands.
- 6. The device of claim 1 wherein an added second pair of tensioning bands are disposed between an anchoring point on the rigid frame and a retention point on the moment arm so as to provide a second increased level of counterforce to the user-induced rotation of the third transverse member.
- 7. The device of claim 1 wherein the rearward second transverse member of the rigid frame is provided with a pair of spaced apart, depending posts that are adapted to receive and support the third transverse members and so to provide a journal box arrangement for the axial rotation of the moment arm as induced by a device user.
- 8. The device of claim 1 wherein the tensioning means comprises a single elongate tensioning band having its longitudinal ends anchored laterally to the moment arm periphery and its intermediate band segments interruptably anchored to the upper edge of the moment arm.
- 9. A portable abdominal muscles and hip fitness exercise device adapted to be positioned during use on a conventional chair support, while being temporarily anchored thereto by the weight of a user seated upon the chair-seating component of the device, comprising:(a) a generally rectangular rigid frame having a first and a second transverse members and opposing left and right hand members conjoined to the transverse member, with the frame adapted to be positioned firmly upon planar element of a conventional chair support; (b) a generally planar seating means sized to overlie the rectangular frame, being secured along its rearward edge to the rearward second transverse member, and secured along its forward edge to the forward first transverse member of the rigid frame; (c) a pair of spaced-apart, elongate handles anchored at the inner longitudinal ends thereof, each conjoined to the longitudinal ends of the second transverse member of the rigid frame, forming rearward corners, with such handles projecting forwardly at an angle relative to the rigid frame; (d) a third transverse member bridging the space between the paired elongate handles and being positioned therebetween, being spaced apart from and below the second transverse member, and being journal-mounted so as to permit the axial rotation thereof; (e) a single L-shaped, lever arm secured pivotally at the one proximal elongate segment thereof to one longitudinal end of the third member, with the lever arm having its distal longitudinal segment aligned both transversely and horizontally, and spaced apart substantially from and above the level of the associated underlying seating means; and, (f) a tensioning means positioned on the same lateral side as the single lever arm, and being operatively associated with such arm, and further comprising: (i) a single horizontal pin fixed intermediate the longitudinal ends of one the right hand member of the rigid frame member; (ii) a plurality of spaced apart, protruding pins which are fixed along the middle of the proximal elongate segment of the forwardly oriented, lever arm; and, (iii) at least one closed loop, extensible band mounted straddling the single pin on the right hand member and concurrently on one of the plurality of protruding pins affixed upon the lever arm.
- 10. The device of claim 9 wherein the plurality of pins are arrayed upon the bowed proximal segment of the lever arm so as to provide progressively larger spans relative to the underlying, single pin from one longitudinal end of the pin array to the other longitudinal end thereof, and being adapted to be conjoined with the lower pin by the alternative selective linking employing the single extensible band.
