  • Climbing device
    Patent number: 9474938
    Abstract: A device for a removable attachment to a column member, such as a tree, includes a body having a pair of spaced contact surfaces. The body also includes a pair of spaced and elongated retention apertures that are configured to receive a flexible retention member, such as a strap, therethrough. The retention member initially retains the device to the column member, such that the contact surfaces are urged against the column member. In addition, the retention members are spaced apart such that their top portions are spaced further apart than their bottom portions. Thus, as the body is forced downward along the column member, the distance between the spaced retention apertures increases, causing the circumferential distance traversed by the retention member to increase, thus drawing the retention member taut.

  • Angle configuring stabilizing assembly for extension ladders
    Patent number: 9187954
    Abstract: A ladder stabilizing assembly for extension ladders has two length adjustable legs attached to opposing sides of the ladder at substantially the midpoint of the working distance of the ladder and two length adjustable braces attached to opposing sides of the ladder near the bottom and are securely attached to the legs. Rods through the hollow rungs attach the legs and braces to the ladder. Heim joints at one end of each leg and brace attach securely to the rods and enable the legs and braces to pivot and swivel for optimum stability placement. The ladder and stabilizer function as a single unit with a wide four point base. The legs and braces are calibrated to assist in setting the ladder at the standard angle for safe use. The stabilizing assembly prevents the ladder from sliding, tipping or other movement and enables the user to work wearing a safety harness.
