ABSTRACT:
A portable tree stand is provided for use by a person to climb to and descend from an elevated position next to an upright object. The stand comprises a pole, a clamping assembly attached to the pole near its top end for securing the pole to the upright object, a device on the bottom end of the pole for anchoring it to the ground and upper and lower foot supports for use by the person to climb and descend the pole. Each foot support is slidably mounted on the pole but has a friction device that locks the foot support in a fixed position on the pole in response to a downwardly applied force.
