A safety hook includes a hook body having an opening, a pivoting portion and a latching portion. A composite link includes a fixing rod and a guiding post. The fixing rod is pivoted at the pivoting portion, and the guiding post has a positioning portion, a sliding groove and a fastening portion. The guiding post encloses the opening through the fastening portion fastened with the latching portion. A rotating kit includes a sleeve and a pin, and the sleeve sheathes the guiding post and coupled to the composite link. A resilience component is sleeved outside the fixing rod and abutted the sleeve. The composite link is restricted when the sleeve is pushed by the resilience component.

An avalanche shovel has a shaft and a grip section that is formed and/or arranged at one shaft end The avalanche shovel has an avalanche probe which can be arranged in the shaft of the avalanche shovel, wherein the grip section exhibits a grip area for gripping and/or holding the avalanche shovel and/or such a grip area is formed on the grip section. The grip section exhibits an insertion and/or removal opening for removal from and/or for insertion of the avalanche probe into the shaft along an insertion axis. A tent can have the avalanche shovel as a tent pole.

A climbing action structure includes a support structure having a plurality of columns configured to be fixed relative to an underlying surface and support at least one header of a plurality of headers above the underlying surface. A climbing action space is defined between the columns, the headers, and the underlying surface that is devoid of intruding structure. The headers define a plurality of action element mounts, each defining a longitudinal axis substantially parallel to the underlying surface. At least one action element is removably coupled to the support structure at a respective action element mount. The action element includes a top end having a header connection member. The header connection member being coupled to the respective action element mount and adjustably positionable along the longitudinal axis, and the action element is disposed within the climbing action space and a participant has 360° access to the action element therein.

System for physical mobility activity of a person, comprising at least one fixed support member and at least one contact member to be worn by the person In motion, wherein the support member and the contact member comprise at least one support surface and at least one contact surface, respectively, wherein the support surface and the contact surface constitute the respective components of a hook-and-loop fastening connection consisting of hooks and loops, wherein the hooks have hook stems and hook openings, wherein the hook openings on the support surface or contact surface in question are at least substantially all situated at the same side of the hook stems in question, when considered in a first direction parallel to the support surface or contact surface in question.

A descender is for work at height, climbing, mountaineering, speleology or other practices using a rope. The descender device for a textile rope (F) includes a casing in which a cam mechanism (10) and an actuating lever (3) for the cam mechanism (10) are housed. The casing (2) includes a return element (13) for the rope (F). The cam mechanism (10) includes a lever pin (29) rotatably actuated by the actuation lever (3) and a movable cam (25) which is rotatably movable between a deactivation position and a locked position in which the movable cam (25) presses on the rope (F) against the return element (13). The lever pin (29) acts on a rocker member (32) which is integral with the movable cam (25) during a first rotation step of the lever pin (29) in a direction opposite to the activation direction of the movable cam (25).

Disclosed are embodiments of rope designs and making and manufacturing of such ropes. In some embodiments, a rope comprises a set of first rope cores, each first rope core of the set of first rope cores comprising a first material; a set of second rope cores, each second rope core of the set of second rope cores comprising a second material, the second material being different from the first material; and a rope sheath configured to encompass the set of first rope cores and the second rope core. In some cases, the rope sheath is braided from a plurality of rope sheath strands.

A clutch assembly for a climbing rope including a tether component pivotally supporting a plate, the plate in turn supporting a pair of pivotal clutch members defining a first pinch point of the rope. A carabiner pivotally attachable to the tether component through an aligning support aperture in the plate. A lever is pivotally attached to the tether component and slidably attached to the plate which permits at least one of sliding displacement or pivoting of the plate relative to the tether component to establish each of a sliding configuration of the rope relative to the clutch members during either of a normal ascent or normal descent condition, as well as a locked configuration of the clutch members against the rope to establish a free-fall preventing condition.
