Abstract
The present invention relates to the field of utility trailers, in particular, utility trailers with rear pivotable gates. The utility trailer includes a trailer bed supported on wheels for rolling motion on the ground. The trailer bed has a floor on which cargo may be placed and a support frame for carrying the floor. The support frame includes a front end; a rear end; and a pair of spaced apart, upper and lower, bent U-shaped members extending between the front and rear ends of the support frame. Each U-shaped member is fabricated from a hollow section having one of a square cross-section and a rectangular cross-section. The support frame further includes a plurality of spaced apart, substantially upright struts extending between, and connecting the upper and lower bent U-shaped members to each other and a plurality of spaced apart cross-members connecting portions of the lower bent U-shaped member to each other. The utility trailer is also provided with a gate pivotally mounted to rear end of the support frame. The gate is movable between a substantially upright position relative to the floor of the trailer bed and a lowered, in-use position.
