Abstract: A portable ladder has two stiles interconnected by rungs. The ladder is provided with a stand off device, including two stand off arm assemblies, each being telescopically inserted into a receiving space. Each stand off arm assembly has a base part and a stand off arm interconnected by a hinge that allows the stand off arm to be pivoted between a position in alignment with the base part and an angled stand off position. The stand off arm assemblies are each configured such that—in extended position—the hinge is located outside the receiving space with the base part being located within said receiving space, and also such that—in retracted position—the base part, the hinge, as well as at least a portion of the stand off arm are located within the receiving space.

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.

Abstract: Apparatus and associated methods relate to a fall-protection safety harness having breathable padding structures located at harness pressure points, including dorsal and shoulder regions, the lumbar region, and leg regions. The padding structures may be constructed to provide air-flow both through and around comfort pads. To provide air-flow through the comfort pads, the padding structures may be made of a sandwich of breathable materials. For example, the padding structures may be made by sandwiching reticulated foam pads between mesh fabric materials. The foam pads may be captured by the two mesh fabrics by a circumferential stitching. Circumferential stitching may permit the reticulated foam to retain its uncompressed form which may facilitate airflow therethrough. Separate and symmetric pads may be located on both sides of a wearer's spine, both at the lumbar region and at the dorsal region of the back, permitting airflow between pads and along the wearer's spine.
