  • Patent number: 11871742
    Abstract: A portable and foldable hunting stand comprises a rigid frame for temporary attachment to a tree that supports a selectively deployable platform adapted to be folded between a generally vertical transportation orientation and a generally horizontal, deployed position. A first platform strut is pivoted with an axis of rotation forming an acute angle relative to the frame. A second platform strut is pivoted relative to said frame with an axis of rotation forming a similar acute angle relative to the frame, but which extends away from the first strut. The platform struts outwardly diverge when the stand is foldably deployed, forming an obtuse angle between them, yielding a generally trapezoidal configuration. A selectively deployable traversing strut may extend between the platform struts in deployment. When the stand is folded for transportation, the platform struts are retracted to assume a parallel vertical, orientation.

  • Patent number: 11859397
    Abstract: An exemplary embodiment of the invention includes a locking mechanism for use with the adjustable toe board to retain the toe board in its retracted position when necessary for transport, storage, or when the size of the portion of the platform the toe board will be used in requires the toe board to be in its fully collapsible state. The locking mechanism may be comprised of a latching member that is capable of automatic locking when the adjustable toe board is moved into its substantially retracted position. Further, the instant invention may be provided in any number of varying adjustable lengths to accommodate the various platform sizing through the use of a uniquely shaped wedge pin that is used with a fork to couple adjustable or non-adjustable toe boards to scaffolds and the like.
