Passive Climbing Protection Device Comprised Of Multiple Components Confined To A Single Stem Which Nest To Create Chocks Of Differing Sizes

Abstract

A passive climbing protection device can be comprised of multiple components that are confined to a single stem which nest to create chocks of differing sizes. The multiple components are sized to enable each smaller component to be nested within the next largest component. Different sized chocks can be formed by simply sliding one or more larger components away from one or more smaller components leaving the smaller components to form a chock of the desired size. Accordingly, the passive climbing protection device provides multiple differently sized chocks on a single stem to enable a large range of placements to be covered with a single device.

What is claimed: 
     
         1 . A passive climbing protection device comprising:
 a stem; and   multiple components secured to the stem which nest to form chocks of differing sizes.   
     
     
         2 . The passive climbing protection device of  claim 1 , wherein larger components are configured to slide along the stem to allow smaller components to form a chock of a desired size. 
     
     
         3 . The passive climbing protection device of  claim 1 , wherein the components have a polygonal shape. 
     
     
         4 . The passive climbing protection device of  claim 3 , wherein the components have one of a four-sided shape or a six-sided shape. 
     
     
         5 . The passive climbing protection device of  claim 1 , wherein one or more of the larger components has one or more sides that are not enclosed. 
     
     
         6 . The passive climbing protection device of  claim 5 , wherein the one or more larger components have two sides that are not enclosed. 
     
     
         7 . The passive climbing protection device of  claim 5 , wherein the one or more larger components have one side that is enclosed. 
     
     
         8 . The passive climbing protection device of  claim 7 , wherein the one or more larger components having one side that is enclosed include one of a groove or a protrusion that corresponds to a protrusion or groove respectively on a smaller component to restrain movement of the one or more larger components with respect to the smaller component. 
     
     
         9 . A passive climbing protection device comprising:
 a stem;   multiple components attached to the stem, the multiple components including a smallest component and a largest component, the largest component having a cavity within which the smallest component can be inserted when the largest component is used to secure the device to a climbing surface.   
     
     
         10 . The passive climbing protection device of  claim 9 , wherein the largest component is configured to slide along the stem to expose the smallest component to allow the smallest component to be used to secure the device to a climbing surface. 
     
     
         11 . The passive climbing protection device of  claim 9 , wherein the largest component includes one or more sides that are not enclosed. 
     
     
         12 . The passive climbing protection device of  claim 11 , wherein the smallest component includes a groove or protrusion that corresponds to a protrusion or groove respectively formed on the largest component to restrain movement between the largest and smallest component. 
     
     
         13 . The passive climbing protection device of  claim 9 , wherein the largest component comprises a single side having a protrusion that inserts into a corresponding groove formed in the smallest component to lock the largest component overtop the smallest component. 
     
     
         14 . The passive climbing protection device of  claim 9 , further comprising:
 one or more intermediate components that are each configured to be nested within the largest component.   
     
     
         15 . The passive climbing protection device of  claim 11 , wherein one or more of the intermediate components has one or more sides that are not enclosed. 
     
     
         16 . A passive climbing protection device comprising:
 a stem;   a first component secured to the stem;   a second component secured to the stem, the second component having a cavity into which the first component inserts when the second component is slid overtop the first component to thereby enable the second component to be used to secure the device to a climbing surface, the second component being slidable along the stem to expose the first component to allow the first component to be used to secure the device to the climbing surface.   
     
     
         17 . The passive climbing protection device of  claim 16 , wherein the second component includes one or more sides that are not enclosed. 
     
     
         18 . The passive climbing protection device of  claim 16 , further comprising:
 a third component secured to the stem, the third component having a cavity into which the second component inserts when the third component is slid overtop the second component to thereby enable the third component to be used to secure the device to the climbing surface, the third component being slidable along the stem to expose the second component.   
     
     
         19 . The passive climbing protection device of  claim 18 , further comprising:
 one or more additional components, each additional component having a cavity into which another of the components inserts when the additional component is slid overtop the other component to thereby enable the additional component to be used to secure the device to the climbing surface.   
     
     
         20 . The passive climbing protection device of  claim 16 , wherein the first and second components have one of four sides or six sides.
