  • Patent number: 5000414
    Abstract: A tree stand comprising an open receptacle shaped to define inner and outer walls on which fastening means are provided to fasten a tree to the receptacle, the fastening means comprising a plurality of pins extending radially about the axis of the tree and slidable within a number of corresponding apertures in the walls of the receptacle. Locking assemblies to interfere with such sliding movement are characterized by a lever having an aperture between its ends for location on the pin between the inner and outer walls of the receptacle, the diameter of the aperture being sufficiently greater than the diameter of the pin to allow the pin to move freely when the lever is in a release position perpendicular to the axis of the pin, while being sufficiently small to interfere with such movement of the pin when the lever is in a lock position, inclined relative to the axis of the pin and in abutment with the pin.
