Abstract: Disclosed is a parawing with an automatic canopy withdrawing mechanism having a canopy, a frame to which the canopy is fastened and on which a pilot can be carried, a propeller mounted on the frame, and a plurality rows of suspension lines interconnecting the canopy and the frame. Also mounted on the frame is an automatic canopy withdrawing mechanism including a reel which may be operated to pull back the suspension lines for withdrawing the canopy. Further, a front pulling rope interconnecting the reel and two rows of suspension lines near the leading edge of the canopy, a rear pulling rope interconnecting the reel and the trailing edge of the canopy, and a plurality of guide rollers for guiding the movement of the front pulling rope and the rear pulling rope are provided so that the suspension lines and the canopy may be withdrawn by the automatic canopy withdrawing mechanism. With the canopy and the suspension lines being withdrawn.

Abstract: A universal physical exercising device includes in combination: a collapsable base supporting frame; a horizontal frame rotatably connected to the base supporting frame through a pair of pivot joints; an adjustable vertical frame structure with a handle member and a pair of vertical sides longitudinally pivoted to a center portion of the horizontal frame; and an elliptical pedal member with foot straps and safety belt fixed at a lower end of the vertical sides of the vertical frame structure. The base supporting frame and the horizontal frame are also provided with a plurality of detachable connecting members for holding the horizontal frame in stationary condition for allowing the vertical frame structure to be operated as a single unit while the vertical frame structure also includes a plurality of anchoring elements for being optionally connected to the horizontal frame so as to be consolidated together for performing either swinging or rotation exercises therewith.

Abstract: A physical training apparatus includes a support frame, a horizontal member pivotally and rotatably mounted to the support frame and a vertical member rotatably mounted on the horizontal member, while on the lower portion of the vertical member there is a revolving disc which is slidable on the vertical member and rotatable about a central axis thereof.
