Abstract
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.
Claims7
A hand climber for supporting a person climbing a tree trunk or similar substantially vertical generally cylindrical member, comprising:
- a. a flexible strap having first and second ends and length greater than the circumference of the tree trunk or similar member, the strap being formed from extruded nylon 6 with yield tensile strength between about 10,000 and about 15,000 psi;
- b. a rigid elongated cylindrical support bar having first and second ends;
- c. first attachment means for attaching the first end of the strap to the support bar at a first attachment point on the support bar inboard from the first end of the support bar by a distance sufficient to allow the person climbing to grip the portion of the support bar between the strap and the first end of the support bar, said first attachment means comprising a hole formed in the strap at the first end of the strap and receiving the support bar, and two collars attached to the support bar, one on either side of the first end of the strap, whereby the strap is retained at the first attachment point;
- and
- d. second attachment means for removably attaching the strap to the support bar at a second attachment point on the support bar inboard from the second end of the support bar by a distance sufficient to allow the person climbing to grip the portion of the support bar between the strap and the second end of the support bar, said second attachment means providing for attachment at any of a series of predetermined locations along the length of the strap beginning at the second end of the strap, said second attachment means comprising a longitudinal series of holes formed in the strap beginning at the second end of the strap, said holes being adapted for receiving the second end of the support bar, and removable retention means for retaining the strap at the second attachment point when the second end of the support bar engages a selected one of the longitudinal series of holes formed in the strap.
