ABSTRACT:
The tensioning device of a tree stand has a tension lever, a ratchet wheel and a tensioning body coaxial therewith, and a lever catch that is movably guided on the tension lever like a ratchet or one-way coupling and that is detachably mechanically linked to the ratchet wheel and that when the tension lever is actuated to create tension engages the teeth of the ratchet wheel such that a part connected to elements for retaining the tree is wound on the tensioning body, thus securely clamping the tree. The tensioning device furthermore has a first catch for engaging the teeth of the ratchet wheel and blocks the latter's rotation in the sense of unwinding of the tensioning body. For each release actuation of the tension lever, the first catch disengages from the teeth of the ratchet wheel, whereby thereupon a second catch blocks the release when the second catch strikes the blocking flank of the tooth of the ratchet wheel in the release direction.
