Abstract
A camming device is provided that has a superior range of operation, is lighter and has lower internal compressive forces. The improvement is a result of using a composition having a co-efficient of friction ranging between 0.35-0.55 affixed to the contact area, for example, a semi-metallic composition. An improved method of fall protection is also provided, as is a method of manufacture.
Claims23
In a camming device for use as protection in cracks during rock climbing, comprising at least one pair of lobes, one axle per pair of lobes, a stem, a loop and a release mechanism, said lobes comprising:
- a face having a contact area;
- an inside edge;
- an apical end;
- and a basal end, to define an inner surface and an outer surface, wherein the improvement comprises:
- a composition comprising at least one metal affixed to said contact area.
In a camming device for use as protection in cracks during rock climbing, comprising at least one pair of lobes, one axle per pair of lobes, a stem, a loop and a release mechanism, said lobes comprising:
- a face having a contact area;
- an inside edge;
- an apical end;
- and a basal end, to define an inner surface and an outer surface, wherein the improvement comprises:
- a composition having a co-efficient of friction ranging between 0.35-0.55 affixed to said contact area.
In a rack of camming devices, for use as protection in cracks during rock climbing, wherein each camming device in the rack comprises at least one pair of lobes, one axle per pair of lobes, a stem, a loop and a release mechanism, said lobes comprising:
- a face having a contact area;
- an inside edge;
- an apical end;
- and a basal end, to define an inner surface and an outer surface, wherein the improvement comprises:
- five camming devices providing an operational range of approximately 4.0 inches.
