Claim 1

Independent Claim 269 words

An integrated boat-trailer apparatus movable on land and on water, comprising: a. vessel means for floating the apparatus when the apparatus is in a body of water; b. support arm means for supporting the apparatus when attached to the transporting vehicle; c. means for pivotally mounting said support arm means with said vessel means at a prow thereof; d. an upper pivot arm; e. means for movably mounting said upper pivot arm at an upper portion thereof with the prow of said vessel means; f. a lower pivot arm; g. means for movably mounting said lower pivot arm at an upper portion thereof with a lower portion of said upper pivot arm. h. means for movably mounting said lower pivot arm at a lower poriton thereof with said support arm means; i. means for moving said upper pivot arm with respect to the prow of said vessel means; j. said upper pivot arm and said lower pivot arm folding and unfolding with respect to each other about said means for movably mounting same in response to said means for moving, wherein said support arm means is moved between an extended position supporting said vessel means on land and a retracted position adjacent the prow of said vessel means when the apparatus is in water; k. channel member means for receiving said support arm means, said upper pivot arm, and said lower pivot arm adjacent the prow of said vessel means when said support arm means is in the retracted position; and l. spring means for holding said support arm means in the retracted position within said channel member means.

Claim 2

Dependent Claim 269 words

An integrated boat-trailer apparatus movable on land and on water, comprising: a. vessel means for floating the apparatus when the apparatus is in a body of water; b. support arm means for supporting the apparatus when attached to the transporting vehicle; c. means for pivotally mounting said support arm means with said vessel means at a prow thereof; d. an upper pivot arm; e. means for movably mounting said upper pivot arm at an upper portion thereof with the prow of said vessel means; f. a lower pivot arm; g. means for movably mounting said lower pivot arm at an upper portion thereof with a lower portion of said upper pivot arm. h. means for movably mounting said lower pivot arm at a lower poriton thereof with said support arm means; i. means for moving said upper pivot arm with respect to the prow of said vessel means; j. said upper pivot arm and said lower pivot arm folding and unfolding with respect to each other about said means for movably mounting same in response to said means for moving, wherein said support arm means is moved between an extended position supporting said vessel means on land and a retracted position adjacent the prow of said vessel means when the apparatus is in water; k. channel member means for receiving said support arm means, said upper pivot arm, and said lower pivot arm adjacent the prow of said vessel means when said support arm means is in the retracted position; and l. spring means for holding said support arm means in the retracted position within said channel member means.

Claim 3

Dependent Claim 31 words

The structure of claim 1, further including; support wheel means mounted with said support arm means for permitting movement of the apparatus when the apparatus is detached from the transporting vehicle.

Claim 4

Dependent Claim 97 words

The structure of claim 1, further including: a. retractable wheel means movable to and from an extended position for supporting the apparatus when the apparatus is on land; b. said vessel means having receiving wheel wells formed therein to receive said retractable wheel means when said wheel means is retracted from the extended position; c. piston means for moving said retractable wheel means to and from the extended position; and d. means for energizing said piston means to move said wheel means, wherein the apparatus may be easily and quickly moved into and out of the water.

Claim 5

Dependent Claim 34 words
