  • Patent number: 4168932
    Abstract: A trailer adapted to carrying a plurality of vehicles, such as snowmobiles, includes a plurality of wheels and a pair of vehicle supporting trailer beds normally disposed in a use position in side-by-side relationship on a frame. Each one of the trailer beds is pivotally mounted on the frame at the rear edge thereof forwardly of the mid-point of the bed to enable it to tilt individually and independently backwardly until its rear edge contacts the ground for loading and unloading purposes and to enable the loaded bed to tilt back to its horizontal use position under the weight of the vehicle supported by it. Bumper devices are disposed on the frame for cushioning the movement of the bed under the weight of the vehicle, and latching devices hold the beds releasably in their horizontal position. Camming devices engage the beds as they move into their use positions for moving the latches to their release position, and spring biasing devices enable the latching devices to return to their holding positions.
