Multi-function pad device with driving mechanism

Claim 1

A multi-function pad device comprising: a pad member; a buoy ring member; a pad sheet member; and a driving mechanism; said pad member being constituted by an inner ring and an outer ring, and the edge portion of said outer ring having several lugs having linking holes therein for use in linking said pad member with other members, and both said inner and outer rings having discrete air chambers therein and inflating valves therefor; said buoy ring member being constituted by a ring-shaped inflatable structure, several lugs mounted around the outer edge thereof, each of said lugs having several linking holes therein for using in linking said buoy ring member with other members, and a linking ring under each lug in which a supporting rod can be mounted, and two symmetrical and parallel auxiliary air chambers on the bottom side of said ring-shaped structure at diametrically opposite positions thereon, oarlocks on the top of said ring-shaped structure at diametrically opposite positions thereon for receiving oars therein, and several projections at spaced intervals around the inside surface of said structure and a bottom ring on the lower inside surface of said ring-shaped structure, said pad member being receivable between said projections and said bottom ring; said pad sheet member being constituted by a polygonal piece of plastic cloth having a suitable toughness and elasticity and having several rope holes along the edge portion thereof for receiving a rope therethrough to convert said pad sheet member into a bag for containing other members of said device for carrying convenience; and said driving mechanism being constituted by a main frame having a front plate and a rear plate having adjacent ends and outer ends, and the outer end of said front plate having a steering member rotatably mounted thereon and which has a handle on the top, a wheel spindle with a wheel on the lower end thereto, and central part of said front plate having a through hole for receiving therethrough an oarlock on said buoy ring member, and the adjacent ends of said front and rear plates having two through holes, and said rear plate having a through hole in the outer end thereof for receiving an oarlock therethrough, a V-shaped pedal seat, both ends of the top of said V-shaped pedal seat having holes, and two inverted U-shaped bolts extending through said plates and the top of said V-shaped pedal seat, and nuts securing said bolts, and the lower end of said V-shaped pedal seat having cranks and pedals at both ends of said cranks, and the front end of each of said pedals having a web-shaped oar plate.
