Abstract: The present invention relates to a via ferrata safety system that improves user safety by increasing the reliable activation of the energy absorption system. The via ferrata system includes a harness coupling member, two fixed cable coupling members, and an energy absorption system. The energy absorption system is coupled to both the harness coupling member and the two fixed cable coupling members. The two fixed cable coupling members are independently coupled to the energy absorption system and to one another. The coupling between the two fixed cable coupling members is proportionally weaker than the independent coupling between the two fixed cable coupling members and the energy absorption system. This proportional weakness of the coupling between the fixed cable coupling members allows each of the fixed cable coupling members to act independently in the event that one of the cable coupling members is coupled to a point between the user and the energy absorption system.

Abstract: A climbing 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 climbing 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 climbing 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: Self-locking bi-foldable load bearing segments are disclosed that can be used in applications such as ladders or ramp. First and second sections of the segment are foldably coupled to transition between an open configuration and a folded configuration. The first and second sections can include rungs pivotally attached to rails that can be further transitioned from the folded configuration to a collapsed configuration, but not transitioned from the open configuration to the collapsed configuration.
