  • Patent number: 4061202
    Abstract: An improved hunting stand which is vertically displaceable from a ground surface and is adapted to be mounted to a supporting element such as a tree. The improved hunting stand includes a platform area where the user may position himself for extended periods of time. Additionally, a sectional ladder is provided which is inserted into the ground and the platform on opposing ends thereof. A stand securing device is mounted to the platform and lockingly engages the supporting element in discrete segmental areas. The stand securing mechanism is adapted to grip the supporting member in a load bearing and frictional interface and not impale the surface of the support element. Additionally, the stand securing mechanism can be attached above or below impeding tree limbs without having to remove the limbs. In this manner, the stand securing device provides for advantageous ecological consequences wherein the external environment is not harmed by the user.
