Abstract
A support platform includes a notch for engaging an upright member, such as a tree or utility pole, and further includes a flexible steel band that encircles the upright member and supports the platform. The band is positioned at an angle extending upwardly and rearwardly from the platform and further supported at either side of the platform with adjustment means to lengthen or shorten the band to accommodate the periphery of the upright member. There is further provided a flexible strap contacting the steel band and which is of sufficient length to be wrapped around the upright member and to serve as a stabilizer for the platform, and which in its preferred embodiment is in the form of an elongated webbing having a buckle member at one of its free ends to releaseably and adjustably engage the other free end after the strap has been wrapped around the upright member and wherein the strap is threaded through an elastomeric sleeve arranged to receive the metal band and thereby retain the webbing or strap against the band when both the band and the strap have been secured in place relative to the upright member.
