Abstract: An airplane with an enlarged safety door in the lower middle part of the fuselage which can be opened during mid-flight emergencies so as to let emergency exit stairs be hydraulically lowered down therefrom. The stairs have a hydraulically operated slideway on the lower end thereof. Chair assemblies which are slidable on rails and which are normally retained by a flip-up board. The chair assemblies can be moved either manually or by means of a motor driven draw cord. A user propelled water safety device comprising an inflatable chest support, two handlebars two inflatable paddlewheels and two floatation devices. A bouyant, collapsible carry-all which can be used to carry survival and safety items upon exit of the plane and which has holes in the bottom thereof for easy draining. An air-flow system comprising an air exhaust shield, a plurality of fans, air vents distributed at even intervals along the ceiling of the plane.

Abstract: It is a multi-function pad device with driving mechanism; particularly, it is a device including a pad, a buoy ring, a pad sheet and a driving mechanism. Upon different elemental members being assembled in different manners, different functions can be provided for recreation activities. The various assemblies not only can be used on water or ground for recreation activities, but also can be used on snow ground, beach or lawn. Further, the device may also be used as a lifeguard on water and transportation for the aquatic product raiser.

Abstract: A manually propelled personal watecraft has a nose portion (12) of rigid, thin plastic material and a frame assembly (14) extending rearwardly therefrom. An inflatable body portion (16) is fastened to the frame assembly. Stabilizers including keel fins (34, 36) extend downwardly from the craft and function to keep the craft upright and to guide the craft straight in the water. A paddle assembly (38) includes a shaft (39) journalled for rotation in the nose portion. U-shaped portions (40, 42) which serve as manual cranks. Paddles (56, 58) are attached to both ends of the shaft outboard of the U-shaped portions. A rider lies in the prone position and propels the craft by rotating the shaft with his arms.

Abstract: A water bicycle comprising two relatively parallel, elongated floating bodies and a frame supported by said floating bodies provided with a seat whereby each of the floating bodies is provided with a frame part supported by the associated floating body and a spacing member is releasably arranged between the two frame parts for maintaining the frame parts at a given distance from the other and the floating bodies connected therewith, the seat being supported by an auxiliary frame provided with two guides cooperating with guides forming part of the frame parts on the floating bodies so that in the longitudinal direction of the floating bodies the guide parts are slidable over or in one another, while bolt are provided for fixing the guides in a desired position relative to one another.

Abstract: A manually powered boat for use as desired by one, two, three or more operators is disclosed. Balanced floatation is maintained regardless of the number of occupants/operators. The boat includes a buoyant hull, a centered, rotatable propulsion assembly enclosed in a housing, and a seat for at least three persons. Cranks for operating the propulsion assembly are included on each side of the housing. Foot pedals are arranged on the cranks to enable operation by a single operator/occupant while sitting in the center of the boat and straddling the housing. Alternately, two persons may sit on either side of the boat. For a three or more person operation, the pedals are positioned to allow adjacent legs and feet of persons seated side-by-side and immediately adjacent one another to be extended and moved in unison for comfort and coordination.

Abstract: A seatless pedal operated vehicular sports device capable of moving our firm surfaces, soft surfaces or liquid surfaces, comprises a seatless frame, a fork having downwardly extending prongs secured for pivotal movement on a forward portion of the frame, the fork having handlebars at its upper end and a front wheel in the form of a hollow cylinder rotatable between its tines. The frame at its lower rear end rotatably carries a cranked pedal assembly disposed between and secured rigidly to two rear wheels in the form of hollow cylinders. The parts are so arranged that the user's weight is borne jointly by the pedal assembly and the handlebars.

Abstract: A small watercraft comprised of a main floatation body having a seat portion. A pair of spaced apart side booms or a continuous U-shaped boom extend forwardly of the main floatation body one to each side of the main floatation body. An open area is defined between the side booms. A crank axle is retained transversely across the side booms over the open area. The crank axle has crank formations formed therein to impart axial rotation of opposed end portions of the axle. Water propelling means are secured to each opposed end portions of the axle to propel the floatation body on a water surface.

Abstract: A conventional bicycle has its frame rigidly supported by a base framework held by adjustable length outrigger arms, whose outer ends are connected with bearings mounted on two spaced floats. The rear bicycle traction wheel frictionally engages and drives a propulsion wheel connected through gearing with a propeller. A tubular arm pivoted at its forward end to the base framework extends rearwardly beneath the bicycle traction wheel and supports the propulsion wheel, gearing and propeller. A pivoted rudder on the rear end of tubular arm is operated by cables extending through such arm and leading to the axle of the front steering wheel of the bicycle. The device possesses windsurfing and rowing capabilities.

Abstract: An aquatic craft for a swimmer; including a pair of pontoons, a frame therebetween on which the swimmer reclines, and a paddle wheel powered by the swimmer.

Abstract: An amphibious vehicle comprises a bicycle wherein the ends of the front wheel shaft and the rear wheel hub shaft are laterally outwardly projected; a water-surface floating apparatus composed of floats each being provided with a foldable air-tight bag and float mounting members therefor loosely rotatable on each of the opposite sides of the bicycle on the front wheel shaft and the rear wheel shaft; a water-surface propulsion apparatus driven through rotation of the rear wheel; and a water-surface steering apparatus mounted on the front wheel.

Abstract: An inflatable boat includes a mechanical propulsion assembly operable by the legs of the user. The inflatable boat has three independent air chambers inflatable to give the boat an operative fork shape. A throw-like shaft mounted in bushes on the branches of the fork shape receives propulsive force from the user's feet. A pair of paddles keyed to the throw-like shaft propel the boat. Shoe-like sheaths may be included on the throw-like shaft for resting the user's feet. When dismantled, the boat does not occupy much space, is easily transportable and is inexpensive.

Abstract: A craft for travel upon a water surface, the craft including a frame mounted upon two spaced apart pontoons, a windshield, a two passenger seat, and a foot powered mechanism mounted on the frame, the mechanism including propellers mounted on foreward-rearwardly and upon sidewardly shafts so that the craft can travel in any direct or any combination of directions.
