Abstract: Two generally triangular segments of metal or plastic are rigidly or pivotably connected at an angle of about 45 degrees. A flexible strap extends through vertical slots formed in each segment. A strap connector, such as a double bar buckle, is positioned between the two segments. The strap extends through the first slot and around a portion of the strap connector, back out the first slot and around the joint between the segments and into the second slot. The strap passes from the second slot, around a portion of the strap connector, back out the second slot and then around the tree. The free ends of the strap are releasably connected. The edges of the segments may have upwardly angled teeth, such that when the tree step is secured against the tree by downward pressure, the upwardly angled teeth restrain the upward return of the tree step in response to the tension in the strap. Installed, strap tension restricts opening of the two segments, while the strap connector restricts collapse of the two segments.

Abstract: Adjustable upper straps extend from the four corners of a collapsible seat assembly and terminate at a central O-ring. A groin strap extends from the central ring to a portion of the seat assembly. A tree ascender strap is also connected to the central ring, and has a latchable hook which can be used to encircle the trunk of a tree and secure the climber as he climbs. A back strap and shoulder strap extend from the central ring and help to restrain a hunter within the assembly both while climbing and while in an elevated position in the tree. A main lead securing strap extends from an extension strap connected to the central ring and has a buckle which allows it to be secured around a tree above the head of the hunter. The main lead securing strap is looped through itself in such a way that the strap chokes the tree trunk within itself to prevent slipping on trees with smooth bark.
