Total Claims: 11
Claim 1
Independent Claim
136 words
A trailer structure providing for convenient transport Of snowmobiles, said trailer structure comprising, a wheel supported frame, a tiltable framework supported by said frame, hinge means interconnecting said frame and framework permitting movement of the latter about a horizontal axis into an inclined tilted position relative to said frame, a tiltable trailer bed carried by said framework and movable therewith into an inclined position for receiving and discharging a load, turntable means mounted on said tiltable framework and tiltable therewith, said turntable means supporting said tiltable trailer bed permitting rotation of the latter for reversing the position of the tiltable bed to facilitate loading and unloading operations, bed-retention means interengageable with said trailer bed and framework to restrain the trailer bed against rotational movement, and locking means for retaining the bed against tilting movement during transport.
