ABSTRACT:
This invention relates to a removable load supporting stand for temporary attachment to a tree trunk or the like for use while hunting for example. According to the invention a stand is provided including a platform extending laterally outwardly from the tree trunk. The platform has a load supporting portion between opposing sides. Engaging means on an inward portion of the platform function to releasably engage an adjacent segment of the tree trunk. A chain at each of it's ends is secured to an opposing side of the platform. The chain releasably encompasses the tree trunk upward of the segment and defines a plane transverse an axis of the tree trunk. The chain is flexible in the plane and resistant to flexure perpendicular to the plane. Biasing means engage the chain and urge the chain in a direction of the plane to disengage the tree trunk. Preferably the chain is comprised of two parallel spaced apart rows of overlapping links transversely interconnected by pins disposed substantially normal to the plane, such that the links and pins define a longitudinal series of apertures therebetween. The biasing means preferably comprise an elongate flexible member having an inherent tendency to assume a selected configuration when unstressed.
