发明名称 Hand climber
摘要 A hand climber for use in climbing trees or similar vertical members includes a rigid cylindrical support bar and a flexible strap. One end of the strap is attached to the support bar at a fixed location on the strap and the other end of the strap is removably attachable to the support bar at any of a series of locations along the length of the strap. The strap is formed from extruded nylon 6 with yield tensile strength between about 10,000 and about 15,000 psi. An extruded rubber sleeve may optionally be slidably positioned on the strap for improved frictional contact with the vertical member being climbed. The hand climber may also optionally include a seat assembly hingedly mounted on the support bar.
