A diamond type cam for rock climbing is provided, which includes a body having an operating member provided thereon, a slide member slidably coupled to the body, a plurality of extension cams each of which has one end that is rotatably coupled to the body and the slide member and an extended end portion that is rotatably hinge-coupled, and a plurality of wires each of which has one end that is coupled to a predetermined position of a lower portion of the extension cam and the other end that is rotatably coupled to a predetermined position of the slide member.

Components, methods, and apparatuses are provided that may be comprise a climbing performance measurement device to measure and/or report climbing-related parameters. In embodiments, the climbing performance measurement device may be worn at a climber's midsection and may include one or more of an accelerometer, a magnetometer, and altimeter, a vibration motor, a gyroscope, one or more computer processors. A climbing performance measurement device may cooperate with other devices, such as a wrist-worn computer or a chest strap to monitor and/or report a climber's heart rate.

In a pole climbing fall prevention assembly having a pole strap, lanyard, and cam assembly that permits adjustment of the pole strap, a lever is attached to the sidewall of a cam assembly to ease the task of a climber needing to adjust the pole strap. A second lever can be attached to the second sidewall of the cam assembly to provide easier access to the lever regardless of the orientation of the cam assembly relative to the climber.

The present invention is a novel device for climbing inside corners, outside corners, and a variety of surfaces. The technology presented herein relies on high friction materials, suction devices, adhesive materials, pneumatic devices, etc. Specifically, embodiments of the present invention are designed to clamp onto inside or outside corners such that the devices weight, and an optional load, can be supported. Further embodiments allow the device to climb up, down, and across corners. Moreover, embodiments that can scale flat, rough, or jagged surfaces are also disclosed.

A power ice screw system including an ice screw and screw adapter configured to engage the ice screw, thus enabling use of a power drill to install the ice screw in an ice feature, is described. The ice screw includes a drive head configured to engage the screw adapter. The screw adapter includes clearing ports that enable the adapter to expel ice that enters the adapter from within the ice screw hollow core. The ice screw core extends through the drive head to permit ice to flow through the ice screw and into the adapter. A cutting member resides within the screw adapter, typically disposed between two clearing ports. The cutting member can be flanked by two flanges configured to direct ice that has been disrupted by the cutting member outwardly through the clearing ports. The power drill is typically a lightweight battery powered electric driver.

The protective overgarment is intended for use by persons who engage in potentially hazardous activities, such as motorcycling and mountaineering. The overgarment is formed of generally circumferential elements that extend around the legs, torso, and arms of the wearer. The circumferential elements are connected by a plurality of connecting elements that extend along the sides of the torso and limbs of the wearer. The elements define corresponding open ventilation passages therebetween, providing greater comfort for the wearer during warm weather. Each of the elements is formed of at least one distinct layer. One layer may be a sheet of resilient rubber or the like. Another layer may be pneumatically inflated or filled with foam plastic material. Yet another layer may also be foam-filled and covered with a stretch fabric for comfort. Additional knee, shoulder, and chest protection is provided by removable rigid plates.

A camming clamping device comprising: a head sub-assembly including a head provided with a cam and a rod sub-assembly having a rod and at least one wire element. The wire element passes through the rod. The rod delineates a through hole designed to receive a connector. The wire element delineates the through hole. The wire element defines at least one loop that is attached to head to constitute a mechanical continuity between the head and the attachment point. The at least one loop is passed through by a tube. The tube and the at least one loop are passed through by an anchorage fixed to the head to constitute the mechanical continuity between the head and the attachment point.
