 of supporting objects for gripping and/or climbing purposes. In addition, the geometry of the device must accommodate the non-parallel walls.
Using the tangential relationship for the minimum friction requirement and assuming a reasonably high friction coefficient for metal on rock of 0.3 to 0.5, the maximum angle between walls is about 30 to 55 degrees respectively (not including the reduction in angle required to perform any useful function). These angles, however, are far from the 90-degree angle of typical corners. The designs used in the prior art are not suited to angles of 30 degrees or more between walls. The present invention is.
In practice, the angle required to produce sufficient grip based on the prior art is much less than 30 degrees. Thus, it is generally acknowledged that the walls of a crack must be nearly parallel to provide a secure anchor. The inability of the prior art to accommodate an angle of more than 30 degrees is due to both the choice of materials that do not achieve a high coefficient of friction and designs that cannot accommodate non-parallel geometries well. To achieve a useful grip on surfaces at angles on the order of 90 degrees, a geometry that can accommodate such angles and a friction coefficient that is greater than one (1) are required. The use of high friction materials and the ability to grip surfaces at angles substantially near 90 degrees to each other has not been previously illustrated in the prior art.
Previously-disclosed climbing systems generally fall into two categories: those which can be used to climb natural objects (such as mountains, cliffs, caves and rocks) and those which can be used to climb man-made objects (such as buildings, scaffolding, towers and poles).
Many clamping and climbing devices have been devised for climbing on rock. Many are designed to grip by applying a force between nearly parallel adjacent surfaces (cracks) in rock. Small blocks, wedges, rods, and chocks have been jammed in cracks and used to secure ropes for climbing protection and securing or hauling loads. The rod-jamming system in Bohn, U.S. Pat. No. 5,934,635 (hereinafter “the '635 patent”) and specially-shaped block devices such as Prohaska, Austrian Pat. No. 395945B (hereinafter “the '945B patent”) are examples. However, they are limited in use to jamming in cracks in which the walls of the crack are nearly parallel.
The '635 patent discloses a self-adjusting rock climber anchor device
of supporting objects for gripping and/or climbing determination. In accession, the geometry of the device must accommodate the non - parallel walls. 
 Using the digressive relationship for the minimum friction requirement and assume a reasonably high clash coefficient for metallic element on rock of 0.3 to 0.5, the maximal angle between walls is about 30 to 55 degrees respectively (not include the reduction in angle required to perform any useful affair). These angles, however, are far from the 90 - degree angle of distinctive corners. The designs practice in the prior artwork are not suited to slant of 30 degrees or more between walls. The present invention is. 
 In practice, the slant required to produce sufficient grip based on the prior art is much less than 30 degrees. Thus, it is generally acknowledged that the walls of a crack must be nearly parallel to provide a secure anchor. The inability of the prior artwork to suit an angle of more than 30 degree is due to both the choice of materials that do not achieve a high coefficient of clash and designs that cannot lodge non - parallel geometries well. To achieve a useful bag on surfaces at angles on the order of 90 degrees, a geometry that can accommodate such angles and a clash coefficient that is greater than one (1) are required. The use of high friction materials and the ability to grip open at angles substantially near 90 degrees to each other has not been previously illustrated in the anterior art.
