Claims
- 1. A variable mode abdominal exercise device comprising:(a) a base seating member having a forward edge and a rearward edge; (b) an elongated rigid first member which is secured lengthwise of the undersurface of the seating member and having one longitudinal free end thereof extending beyond the forward edge of the seating member terminating in an acute angle configuration; (c) an elongate resilient member having a longitudinal lower end and a longitudinal upper end, such resilient member extending generally upwardly and outwardly from the forward edge of the seating member; (d) means for pinning the lower end of the resilient member to the longitudinal free end of the rigid first member; (e) a collar-like member mounted proximal to the upper longitudinal end of the resilient member and adapted to provide means for the interlocking support thereof with other components; (f) a bracket means having inner and outer longitudinal ends operatively engaging the collar-like member in a reciprocal slidable mode, and being adapted for variable positioning along the elongate length of the collar-like member; (g) a first locking means proximal the inner longitudinal end of the bracket means adapted for fixing the position thereof relative to the collar-like member; and, (h) a grippable bars assembly mounted to and adapted for axial rotation about the outer longitudinal end of the bracket means.
- 2. The device of claim 1 wherein the collar-like member is provided with a pair of diametrically opposing elongate linear slots located along the outer surface thereof, which slots track the variable bracket means movement upwardly and downwardly for user height adjustment.
- 3. The device of claim 1 wherein the bracket means is provided with a pair of opposing linear elongate ridges adapted for tracking within the opposing pair of elongate linear slots provided in the outer periphery of opposing collar-like means.
- 4. The device of claim 1 wherein the bracket means is provided with a transverse linear bore proximal to the outer end thereof adapted for pivotally engaging a central shaft segment of the handle bar assembly.
- 5. The device of claim 1 wherein the means for pinning the resilient member lower end to the longitudinal end of the first member is a sleeve-like fixture adapted to receive the lower end of the resilient member at its upper end and secured fixedly to the outer free end of the first elongate member.
- 6. The device of claim 1 wherein the bracket means is interuptably secured to the collar-like member by a thumb screw which transverses the inner end thereof and compresses the split ends of the bracket means about the upper end of the collar.
- 7. The device of claim 1 wherein the outer end of the bracket means is axially traversed by a second locking means that contacts the central segment of the handle bar assembly serving to retain any preset juxtaposition of the bars assembly relative to the normally set orientation of the resilient member and the bracket means.
- 8. The device of claim 1 wherein first member free end terminates in an acute angle configuration which supports and anchors the fastening means for anchoring the elongate resilient member to the rigid first member.
- 9. The device of claim 1 wherein the first locking means includes a grippable feature that provides for interruptible locking engagement with the engaged collar-like member.
- 10. The device of claim 1 wherein the resilient member is pitched forwardly from the vertical orientation so as to facilitate both vertical and horizontal deflection from the at rest orientation.
