Pontoon log body and method for producing same

Claim 3

A method for manufacturing a flotation device as set forth in claim 1, further including the step of: (i) applying a sealing tape intermediate opposing connection portions to provide the sealing means.

Claim 4

A method for manufacturing a sectional flotation device as set forth in claim 1, further including the step of: (i) fastening a structural member to the device with fastening means placed through the securing means, opposing connection portions and intermediate sealing means without destroying the waterproof seal formed by opposing connection portions and intermediate sealing means.

Claim 5

A flotation device comprising: (a) a pair of water impervious sections including a generally hull-shaped body section and an adjoining top plate section, (b) at least one connection portion on each section, the generally hull-shaped body including a perimeter flange and the top plate section including a flange portion, (c) adjoining sections having their respective connection portion in opposition, (d) sealing means intermediate opposing connection portions, (e) elongate securing means forced over opposing connection portions and intermediate sealing means, thereby reducing the thickness of the combination of opposing connection portions and intermediate sealing means, (f) the elongate securing means including gripping means for holding the elongate securing means in positions over opposing connection portions and intermediate sealing means, the elongate securing means further including a generally U-shaped clip having a gripping sawtooth surface engaging the opposing connection portions, whereby the clip, forced over the opposing connection portions and intermediate sealing means generally parallel to the perimeter flange and the flange portion, tends to grip the opposing connection portions and hold the generally U-shaped clip in place, and (g) fastening means placed through securing means, opposing connection portions and intermediate sealing means, whereby the waterproof seal formed by the opposing connection portions and intermediate sealing means is not destroyed even though the fastening means pierce.

Claim 6

A flotation device comprising: (a) a pair of water impervious sections including a generally hull-shaped body section and an adjoining top plate section, (b) at least one connection portion on each section, the generally hull-shaped body including a perimeter flange and the top plate section including a flange portion, (c) adjoining sections having their respective connection portion in opposition, (d) sealing means intermediate opposing connection portions, (e) elongate securing means forced over opposing connection portions and intermediate sealing means, thereby reducing the thickness of the combination of opposing connection portions and intermediate sealing means, (f) the elongate securing means including gripping means for holding the elongate securing means in positions over opposing connection portions and intermediate sealing means, the elongate securing means further including a generally U-shaped clip having a gripping sawtooth surface engaging the opposing connection portions, whereby the clip, forced over the opposing connection portions and intermediate sealing means generally parallel to the perimeter flange and the flange portion, tends to grip the opposing connection portions and hold the generally U-shaped clip in place, and (g) fastening means placed through securing means, opposing connection portions and intermediate sealing means, whereby the waterproof seal formed by the opposing connection portions and intermediate sealing means is not destroyed even though the fastening means pierce.

Claim 7

A flotation device as set forth in claim 4, further including: (h) a structural member attached to the device with attachment means placed through the securing means, opposing connection portions and intermediate sealing means without destroying the waterproof seal formed by the opposing connection portions and intermediate sealing means.

Claim 8

A flotation device as set forth in claim 4, wherein the sealing means comprises: (h) a compressible sealing tape, having an adhesive on at least one surface.

Claim 9

A pontoon boat formed from a pair of flotation devices, each device comprising: (a) a hull-shaped body having an outwardly extending peripheral flange, (b) a top plate having a peripheral flange disposed adjacent the flange of the hull-shaped body, (c) compressible foam sealing tape disposed substantially continuously intermediate the adjacent flanges, (d) an elongate U-shaped securing clip having opposed sawtooth flanges spaced apart at distance less than the combined thickness of the adjacent flanges and the uncompressed foam sealing tape prior to engagement with the adjacent flanges, said sawtooth flanges having backward facing teeth to facilitate driving said clip generally parallel to the adjacent flanges into securing engagement and retaining said clip in position, and (e) a plurality of rivets disposed at spaced intervals along the flanges to fasten the clip in position.

Claim 10

A pontoon boat formed from a pair of flotation devices, each device comprising: (a) a hull-shaped body having an outwardly extending peripheral flange, (b) a top plate having a peripheral flange disposed adjacent the flange of the hull-shaped body, (c) compressible foam sealing tape disposed substantially continuously intermediate the adjacent flanges, (d) an elongate U-shaped securing clip having opposed sawtooth flanges spaced apart at distance less than the combined thickness of the adjacent flanges and the uncompressed foam sealing tape prior to engagement with the adjacent flanges, said sawtooth flanges having backward facing teeth to facilitate driving said clip generally parallel to the adjacent flanges into securing engagement and retaining said clip in position, and (e) a plurality of rivets disposed at spaced intervals along the flanges to fasten the clip in position.

Claim 11

A pontoon boat as set forth in claim 7, wherein: (f) a nose member is provided for each prow section, (g) the clip extends substantially to the nose member and the sealing tape is longitudinally spaced from the nose member and the top plate is welded to the flange along the tapeless space.

Claim 12

A pontoon boat formed from a pair of flotation devices, each device comprising: (a) a hull-shaped body having an outwardly extending peripheral flange, (b) a top plate having a peripheral flange disposed adjacent the flange of the hull-shaped body, (c) compressible foam sealing tape disposed substantially continuously intermediate the adjacent flanges, (d) an elongate U-shaped securing clip having opposed sawtooth flanges spaced apart a distance less than the combined thickness of the adjacent flanges and the uncompressed foam sealing tape, said sawtooth flanges having backward facing teeth to facilitate driving said clip into securing engagement and retaining said clip in position. (e) a plurality of rivets disposed at spaced intervals along the flanges to fasten the clip in position, (f) the assembled flanges, sealing the tape and clip of each flotation device include a plurality of openings extending therethrough, (g) a plurality of transverse members having corresponding openings extend between the flotation devices, and (h) a plurality of bolt fasteners connect said transverse members to said flotation device.

Claim 13

A pontoon boat formed from a pair of flotation devices, each device comprising: (a) a hull-shaped body having an outwardly extending peripheral flange, (b) a top plate having a peripheral flange disposed adjacent the flange of the hull-shaped body, (c) compressible foam sealing tape disposed substantially continuously intermediate the adjacent flanges, (d) an elongate U-shaped securing clip having opposed sawtooth flanges spaced apart a distance less than the combined thickness of the adjacent flanges and the uncompressed foam sealing tape, said sawtooth flanges having backward facing teeth to facilitate driving said clip into securing engagement and retaining said clip in position. (e) a plurality of rivets disposed at spaced intervals along the flanges to fasten the clip in position, (f) the assembled flanges, sealing the tape and clip of each flotation device include a plurality of openings extending therethrough, (g) a plurality of transverse members having corresponding openings extend between the flotation devices, and (h) a plurality of bolt fasteners connect said transverse members to said flotation device.
