Abstract: A portable shelter for a tree blind including an upper tree gripping bracket and a tension member extending from the upper tree gripping bracket and operatively connecting to an overhead frame. A vertical spacing member maintains a vertical distance between the upper tree gripping bracket and a lower tree gripping bracket. A compressive member extends between the vertical spacing member and the overhead frame and the compressive member is adjustable relative to the vertical member. A rain fly covers the overhead frame.

Abstract: A adjustable bed extender which is attachable to the receiver orifice of a standard receiver hitch is disclosed. The device provides support for loads which extend beyond the bed of a truck or any vehicle having a bed. The device includes a drawbar which fits into the receiver orifice of the hitch already permanently to the vehicle, a support assembly which supports the load, and an adjustable connection between the support assembly and drawbar for adjusting the height of the support assembly for different vehicle models and tailgate configuration.
