Abstract: An improved bolt hanger defines a hanger that exerts an outward force on the bolt that secures the hanger to a rock wall, urging the bolt outwardly under tension, and thereby helping to prevent the bolt from coming loose over time. The improved bolt hanger has a concave shape formed into it centered around the bolt hole. As the bolt is tightened into the bore in the rock, the head of the bolt (and/or an underlying washer) causes the concave portion to compress. This compression causes the concave portion of the hanger to exert an outward force on the bolt, which makes loosening the bolt more difficult. Furthermore, the hanger according to the present invention has a complex geometry on the rock-contacting surface that aids in the prevention of rotation of the hanger when under load. The bolt hanger may be used with a modified bolt adapted for use with the improved hanger.

Abstract: A climbing quickdraw is defined by first and second carabiners interconnected by looped webbing that has been overlapped and stitched to define a central, interconnecting portion that has four layers, and carabiner openings that are double layered. The length of webbing is formed in a loop such that the webbing is doubled over on itself until the ends are almost even with each other but not overlapping. The loop is then pressed flat so that the splice is near the center of the flattened loop and the webbing is four layers thick. The webbing is then securely sewn through all four layers on both sides of the splice, leaving an open loop at each end for attaching a carabiner. The new quickdraw can be made from woven webbing or from braided webbing. Braided webbing can be made of stretchy, energy absorbing nylon, giving the quickdraw energy absorbing properties. The braided webbing will also have mechanical properties that will allow it to stretch and absorb energy.

Abstract: A climbing cam having opposed asymmetrically sized cam members to eliminate the interference that limits the expansion range of climbing aids of the cam type. An optional cam member provides an opposing force to assist in maintaining the placement of the cam in the rock.

Abstract: A climbing nut is generally trapezoidal and has planar upper and lower faces and paired adjacent faces that are convex and concave, respectively. Opposed faces of the nut are therefore convex and concave, respectively. The convex faces have lateral longitudinally extending leg segments that assist in triangulation and strengthen the nut. The geometry of the faces allows for greater placement options. The nut alternately has one or more asymmetric curved faces. The nut is milled from stock extrusion material.

Abstract: A rope hook comprises a length of tubular fabric webbing into which a pair of loops has been formed. The first loop serves to attach the hook to an object. A resilient U-shaped member is contained within the tubular webbing to define a U-shaped member for holding a coil of rope. An adjustable fastener spans the opening into the hook for engagement with the second loop.

Abstract: A pair of pants includes a closure system in which the first end of a belt is fixed to the waistband of the pants at the first flap of the fly opening. The belt extends circumferentially around the waistband and is adjustably connected to the second end of the waistband near the underlapping flap of the fly opening, without spanning the fly opening between the overlapping and underlapping flaps. The belt length may be adjusted. Because the belt does not span the fly opening the fly may be opened and closed in a standard fashion without the need to disconnect or reconnect the belt each time the fly is opened. The belt length need be set only once.

Abstract: A climbing chock includes a chock body which has an irregular tubular configuration with multiple bearing surfaces thereon. At least two of the surfaces are convex in shape and at least one of the surfaces is flat. The chock includes a sling which is attached to the chock body for supporting a climber.
