Abstract
This invention relates to a towable trailer, having an inner and outer frame, that function as levers, to lower the load bed horizontally to ground level. The levers are pivotally attached at the rear of the trailer. The trailer has a hinged tongue portion that when raised, allows cargo such as snowmobiles, to be driven or unloaded off of the front of the load bed while the load bed remains on ground level.
Claims2
A trailer, comprising:
- A. A U-shaped outer frame, having two parallel outer side rails, opened in the rear and joined by a front rail to form a rigid structure;
- B. A rectangular inner frame, positioned inside the outer frame, having side members, a front member and a rear member formed in a rigid structure, with a shaft positioned in the rear member of the inner frame in which the shaft ends are situated within outer frame sleeves, that are fixed to ends of the outer frame side rails, and in which said shaft pivots to effect pivoting of the frames relative to each other;
- C. A hinged forward end portion that pivots around and is attached to pivot pins located on the side rails, and includes means for allowing pivotal raising of the entire hinged forward end portion upwardly away from the inner and outer frames with the exception of the portion of the forward portion attached at the pivot pins to allow the unloading of cargo from the front of the trailer.
