ABSTRACT:

This invention pertains generally to kayaks and, more particularly, to an inflatable kayak which can be rolled up and folded for transportation and storage.
Heretofore, kayaks have been constructed in a number different ways. Older kayaks typically had rigid frames covered with skins, while newer ones have been molded of fiberglass or other rigid plastic materials. Others have been made of buoyant materials such as plastic foam as described in U.S. Pat. No. 3,150,386. A foldable kayak having a hinged frame with inflatable tubes for tightening a skin on the frame is disclosed in U.S. Pat. No. 4,057,865.
An inflatable boat having rigid bow and stern sections attached to an inflatable tube to form a canoe-like structure is shown in U.S. Pat. Nos. 1,555,080, 1,631,047. Other examples of inflatable boats are found in U.S. Pat. Nos. 1,419,545, 3,359,579, 3,935,607 4,057,865, 5,046,978, and 5,564,357. Inflatable boats having multiple chambers for added safety are shown in U.S. Pat. Nos. 4,750,446, 4,782,777 and 5,304,082.
Some inflatable kayaks have also been available commercially from companies such as Aire Inflatables in Boise, Id. Such kayaks have been relatively expensive and have also had other limitations and disadvantages.
It is in general an object of the invention to provide a new and improved inflatable kayak.
Another object of the invention is to provide an inflatable kayak of the above character which overcomes the limitations and disadvantages of the kayaks and other inflatable boats heretofore provided.
These and other objects are achieved in accordance with the invention by providing an inflatable kayak having a pneumatically inflatable peripheral tube with elongated side sections which come together fore and aft to form a passenger compartment, a cover of flexible material encasing the tube and forming a substantially inelastic skin against which the tube can be inflated to form a relatively rigid structure, and a sheet of material more durable than the cover spanning beneath the passenger compartment and extending along the lower and outer sides of the tube and cover to form a floor for the passenger compartment and a protective sheath for the tube and cover. A splash skirt of flexible material is attached to the cover and extends between the side sections of the tube over the forward portion of the passenger compartment.
