Abstract
Abstract A trailer to be towed by a vehicle for transporting a car and a boat having a first support assembly adapted to carry the car. A second support assembly is adapted to carry the boat and is movable between a lower and raised position. Two pairs of pivoted scissor arms are slidably secured to opposite sides of the first and second support assemblies. Hydraulic actuators are used to actuate the scissor arm pairs thereby to move the second support assembly between its raised and lowered positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
A trailer for transporting a single car and a single boat comprising a first support assembly adapted to carrying said car, a second support assembly adapted to carrying a boat movable from a lower position immediately above said first support assembly to a raised position above said first support assembly to provide clearance for said single car, a first and a second pair only of pivoted scissor arms slidably secured to opposing sides of said first and second support assemblies, hydraulic means coupled only to said first and second scissor arm pairs for actuating said scissor arm pairs to move said second support assembly between the raised and lowered position whereby solely said hydraulic means and said first and second scissor arm pairs are effective to move said second support assembly between said positions, an upright support releasably secured to said second support assembly when in the raised position to provide support to said second support assembly, said upright support being fixedly secured to said first support assembly adjacent one end of said trailer, and said first and second pair of scissor arms being disposed adjacent the opposing end of said trailer thereby to provide support for the raised second support assembly at said ends of said trailer.
Claim 2
Dependent Claim
208 words
A trailer for transporting a single car and a single boat comprising a first support assembly adapted to carrying said car, a second support assembly adapted to carrying a boat movable from a lower position immediately above said first support assembly to a raised position above said first support assembly to provide clearance for said single car, a first and a second pair only of pivoted scissor arms slidably secured to opposing sides of said first and second support assemblies, hydraulic means coupled only to said first and second scissor arm pairs for actuating said scissor arm pairs to move said second support assembly between the raised and lowered position whereby solely said hydraulic means and said first and second scissor arm pairs are effective to move said second support assembly between said positions, an upright support releasably secured to said second support assembly when in the raised position to provide support to said second support assembly, said upright support being fixedly secured to said first support assembly adjacent one end of said trailer, and said first and second pair of scissor arms being disposed adjacent the opposing end of said trailer thereby to provide support for the raised second support assembly at said ends of said trailer.
Claim 3
Dependent Claim
31 words
The trailer of claim 1 in which said hydraulic means comprises only first and second horizontally disposed hydraulic assemblies coupled respectively only to said first and second pairs of scissor arms.
Claim 4
Dependent Claim
40 words
The trailer of claim 1 in which there are provided further support members releasably coupled between said first and second support assemblies with the second support assembly in the raised position to provide further support for towing of said boat.
Claim 5
Dependent Claim
26 words
