  • Patent number: 4775030
    Abstract: An inexpensive tree step is provided that permits a hunter to climb a tree and then remove a portion of the assembly so that the hunters tree stand or steps cannot be stolen.This is accomplished by using a conical pointed screw with a threaded countersunk head which can receive another screw which can easily be connected and disconnected. The unit can also be made of special type treads and special type head.To use the tree step, the hunter merely turns the screw portion into the tree. This conical screw is left in the tree for the duration of the hunting season or until the hunter no longer desired this location. The step portion of the tree step is carried into and out of the woods each day. The threads can be made special so that no other hunter could use a lag bolt or other commercial bolts to attach to the screws in the tree. The step portion also has a handle on the end to act as a stop for the hunter's foot and as a handle to insert and remove the step from the screw.
