ABSTRACT:
A portable trailer movable over a surface, includes a frame and a support leg connected to the frame. The support leg has a flexible joint including a first support member, a second support member separate from the first support member and a flexible member spanning a gap between the first and second support members. The flexible member preferably joins the first and second support members so that said first and second support members are capable of moving into one or more non-parallel orientations relative to one another for preventing damage to the support leg when the support leg comes in contact with the surface or an object on the surface. The support leg may also include a second flexible joint.
