Abstract:
1. A folding collapsible exercising machine comprising: a base frame, said base frame comprising a front frame bar, two side frame bars respectively extending from two distal ends of said front frame bar at right angles and arranged in parallel, said side frame bars each having a respective free end terminating in a smoothly arched endpiece for enabling said base frame to rock on the floor, a rear frame bar connected between said two side frame bars, two rails respectively fastened to said side frame bars in flush with a bottom side of each of said side frame bars for supporting the folding collapsible exercising machine on a floor, said rails each having a sliding groove, and an upright support upwardly extending from a middle part of said front frame bar, said upright support having two sidewalls, a front wall connected between said two sidewalls, and a screw hole formed in said front wall; a seat pad, said seat pad having a rear bottom side thereof fixedly fastened to said rear frame bar of said base frame and a front bottom side connected to said front frame bar of said base frame; two angle plates respectively connected between the front bottom side of said seat pad and said front frame bar of said base frame to support said seat pad in a sloping position; two damping spring members respectively slidably mounted in the sliding grooves of said rails and adapted to impart a damping resistance to said base frame when rocking said base frame on the floor, said damping spring members each having a handle fixedly fastened to a front end thereof for grasping with the hand to move the respective damping spring member in and out of the respective sliding groove to adjust the damping resistance; a leg extension bar, said leg extension bar comprising a horizontal shaft, two cylindrical cushions wrapped about the periphery of said horizontal shaft, said horizontal shaft having a front lug on the middle, and a vertical shaft perpendicularly extending from a middle part of said horizontal shaft and pivotally connected to said upright support of said base frame for enabling said leg extension bar to be turned relative to said base frame between a first position where said vertical shaft is in vertical alignment with said upright support of said base frame and a second position where said leg extension bar is closely attached to said seat pad, said vertical shaft having a locating hole in a bottom end thereof; a lock screw for threading into the screw hole in the front wall of said upright support of said base frame and the locating hole of the vertical shaft of said leg extension bar to lock said leg extension bar in said first position; and a handlebar, said handlebar comprising a transverse rod, and a longitudinal rod perpendicularly extending from a middle part of said transverse rod and pivotally connected to the front lug of said horizontal shaft of said leg extension bar for enabling said handlebar to be turned relative to said leg extension bar between an extended position where said longitudinal rod is supported on said horizontal shaft of said leg extension bar and a received position where said handlebar is closely attached to the vertical shaft of said leg extension bar.
