Amphibious motor bike

Claim 2

An amphibious motor bike including: a. a collapsible pontoon removably mounted on each side of the bike, each pontoon comprising: b. a plurality of top flat rigid members arranged in a linear direction and extending from end to end of the pontoon, the opposed edges of adjacent flat members being spaced a slight distance apart; c. an inflatable member extending from end to end of the linearly aligned members and being secured to the undersurfaces of said members so as to act as hinges between adjacent flat members for permitting the flat members to be folded into parallel arrangement with respect to each other when the inflatable member is deflated; and d. means for removably securing said pontoons to the sides of the motor bike for supporting the bike on a body of water when the inflatable member is inflated.

Claim 3

The combination as set forth in claim 1: and in which a. said pontoon securing means including: b. a first pair of elongated tubular members, non-circular in cross section, one tubular member being secured to each side of the motor bike and extending lengthwise thereof; c. a pair of U-shaped members, non-circular in cross section, for each elongated tubular member; one leg of each U-shaped member being removably mounted in each end of said elongated tubular member so that each elongated tubular member will support a pair of U-shaped members with the free leg of each pair extending toward the free leg of its associate U-shaped member; d. a sleeve, non-circular in cross section mounted on the rigid member disposed at each end of each pontoon, said sleeves removably receiving the free legs of said U-shaped members with the ends of the free legs projecting beyond said sleeves; and e. a second pair of elongated tubular members, each one overlying the flat rigid members of one of said pontoons and having its ends receiving the ends of the free legs that extend beyond said sleeves; f. whereby the non-circular cross sections of the first pair of elongated tubular members and the two pairs of U-shaped members will rigidly hold said U-shaped members against any relative movement with respect to said first pair of elongated tubular members and said second pair of elongated tubular members will add greater rigidity to the flat rigid pontoon members over which the second pair of elongated tubular members extend.

Claim 4

The combination as set forth in claim 2: and in which a. said motor bike has a pontoon carrier disposed on each side of the bike and each one adapted to hold one of the pontoons when the inflatable member has been deflated and when the flat rigid members of the pontoon have been folded into parallel arrangement with respect to each other.

Claim 5

An amphibious motor bike including a rear drive wheel and tire for the bike; a. a water paddle removably mounted on the tire of said drive wheel and comprising: b. a plurality of links hingedly connected together to form a row of links that can encircle the tire so that each link is substantially the same distance from the center of the wheel; c. each link having a pair of side members designed to grip the sides of the tire; and d. each link having an outwardly and radially extending paddle portion that will extend transversely across the tire, the end links of the water paddle being removably connected together; e. whereby a rotation of said drive wheel will rotate said water paddle therewith.

Claim 6

An amphibious motor bike including a rear drive wheel and tire for the bike; a. a water paddle removably mounted on the tire of said drive wheel and comprising: b. a plurality of links hingedly connected together to form a row of links that can encircle the tire so that each link is substantially the same distance from the center of the wheel; c. each link having a pair of side members designed to grip the sides of the tire; and d. each link having an outwardly and radially extending paddle portion that will extend transversely across the tire, the end links of the water paddle being removably connected together; e. whereby a rotation of said drive wheel will rotate said water paddle therewith.

Claim 7

The combination as set forth in claim 4: and in which a. each link is made from a single blank that has an oval opening and a transverse edge spaced from one end of the oval opening to provide a water paddle area, the opposite end of the blank being formed into a tongue portion; b. said blank also having parallel edges that are spaced from the sides of the oval opening, the blank being folded along transverse lines to provide the link with side members that can grip the sides of a tire, the tongue being bent on a transverse fold line and having its outer edge secured to said water paddle area at a spaced distance from said transVerse edge; and c. a pair of cables secured to the undersurfaces of the tongues for the adjacent links, said cables extending through openings in the water paddle area of each link.
