Abstract
Abstract An apparatus for loading, unloading and storing a jet propelled water vehicle comprising a first pair of tubes made of relatively smooth surfaced plastic plumbing pipe or the like, a second pair of tubes of similar construction which telescope within and extend from the first pair of tubes and devices to adjustably support and space the first pair of tubes on a truck bed, mini-van floor, trailer frame, elevated rack or the like. When the first pair of tubes are mounted in a pickup truck bed for example and the second pair of tubes are drawn out as an extension of the first pair of tubes, a jet propelled vehicle can be loaded directly from the water by applying the weight of the vehicle to bend the second pair of tubes and after a short jet burst propelling the vehicle along the tubes with the grooves in the hull of the vehicle engaging the tubes. In another mode the vehicle slides on the tubes onto a storage rack directly from the water or from the bed of a pickup truck or the like.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
324 words
An apparatus for loading, unloading and storing a jet propelled water vehicle of the type having a pair of parallel grooves formed in its hull and extending for substantially the length thereof comprising: (a) a first pair of horizontal parallel hollow tubes having substantially smooth external surfaces and of a shape and size suited to serving as supporting tracks for sliding the jet propelled water vehicle thereon between leading and trailing ends thereof with the hull grooves thereof resting on said tubes; (b) a second pair of parallel hollow tubes having substantially smooth external surfaces slidably mounted within said first pair of tubes and extendable therefrom to provide an extension of the supporting tracks formed by said first pair of tubes, said second pair of tubes having leading and trailing ends and in one mode being bendable such that when the leading ends of each of the second pair of tubes are nested in respective trailing ends of said first pair of tubes, said second pair of tubes tend to bend when the weight of the jet propelled water vehicle is received by the trailing ends of said second pair of tubes in transferring the vehicle from the second to the first pair of tubes and in another mode when said second pair of tubes rest on a support located at substantially the same elevation as said first pair of tubes, said second pair of tubes provide horizontal supporting tracks for storing said vehicle; (c) first support means for adjustably spacing and supporting the said leading and trailing ends of said first pair of tubes; and (d) spacer means joining the trailing ends of said second pair of tubes and operative to maintain said trailing ends of said second pair of tubes spaced apart a distance substantially equal to the distance said first pair of tubes are spaced apart and mating the spacing of the hull grooves of the vehicle to be transported thereon.
Claim 2
Independent Claim
324 words
An apparatus for loading, unloading and storing a jet propelled water vehicle of the type having a pair of parallel grooves formed in its hull and extending for substantially the length thereof comprising: (a) a first pair of horizontal parallel hollow tubes having substantially smooth external surfaces and of a shape and size suited to serving as supporting tracks for sliding the jet propelled water vehicle thereon between leading and trailing ends thereof with the hull grooves thereof resting on said tubes; (b) a second pair of parallel hollow tubes having substantially smooth external surfaces slidably mounted within said first pair of tubes and extendable therefrom to provide an extension of the supporting tracks formed by said first pair of tubes, said second pair of tubes having leading and trailing ends and in one mode being bendable such that when the leading ends of each of the second pair of tubes are nested in respective trailing ends of said first pair of tubes, said second pair of tubes tend to bend when the weight of the jet propelled water vehicle is received by the trailing ends of said second pair of tubes in transferring the vehicle from the second to the first pair of tubes and in another mode when said second pair of tubes rest on a support located at substantially the same elevation as said first pair of tubes, said second pair of tubes provide horizontal supporting tracks for storing said vehicle; (c) first support means for adjustably spacing and supporting the said leading and trailing ends of said first pair of tubes; and (d) spacer means joining the trailing ends of said second pair of tubes and operative to maintain said trailing ends of said second pair of tubes spaced apart a distance substantially equal to the distance said first pair of tubes are spaced apart and mating the spacing of the hull grooves of the vehicle to be transported thereon.
Claim 3
Dependent Claim
38 words
An apparatus for loading, unloading and storing a jet propelled vehicle as claimed in claim 1 including means detachably mounting said first support means in the bed of a second vehicle used for transporting said jet propelled vehicle.
Claim 4
Dependent Claim
35 words
An apparatus for loading, unloading and storing a jet propelled vehicle as claimed in claim 1 including a rack providing an elevated support and means detachably mounting said first support means on said elevated support.
Claim 5
Dependent Claim
38 words
An apparatus for loading, unloading and storing a jet propelled vehicle as claimed in claim 1 including means detachably mounting said first support means on a trailer frame forming part of a trailer towed by a second vehicle.
Claim 6
Dependent Claim
28 words
An apparatus for loading, unloading and storing a jet propelled vehicle as claimed in claim 1 including means detachably mounting said first support means on a second support.
Claim 7
Dependent Claim
122 words
An apparatus for loading, unloading and storing a jet propelled vehicle as claimed in claim 1 wherein said first support means includes a first pair of support blocks for supporting and fitted to the shape of the leading ends of said first pair of tubes, a second pair of support blocks for supporting and fitted to the shape of the trailing ends of said first pair of tubes, a first channel for adjustably supporting said first pair of blocks, a second channel for adjustably supporting said second pair of blocks, means for detachably mounting said channels on a second support such as a truck bed, elevated rack, towed trailer or the like and means for adjustably positioning said blocks on said channels.
