Abstract
Abstract The tree stand has a notch which receives a tree trunk and has a flexible steel band encircling and engaging the tree. The band is positioned at an angle extending upwardly and rearwardly from the platform. The band is supported by means at each side of the platform including front and rear legs pivoted on the platform and slideably interconnected. When the legs are raised from their storage position against the platform, they are automatically locked together when they reach their operative position. One leg carries a guide which receives the band. A cylindrical member fixed on the guide supports a plunger which is biased to engage holes in the band. A cam-type actuator bears against the cylindrical member and is moved relative to the plunger between a lock position (plunger engaging the band) and a retracted position (plunger withdrawn from the band). A lock screw can fix the actuator relative to the plunger to prevent accidental movement of the actuator to the released position. This lock is independent of the lock for the legs and the locks can be operated separately. The legs are made of flat flexible metal so the legs can move sideways without need for universal joints.
