Abstract

A crack climbing unit is provided and comprises a body having an inwardly facing jamming surface. The surface is provided with a compliant liner.

1 . A crack climbing unit comprising a body having an inwardly facing jamming surface, the surface being provided with a compliant liner. 
     
     
         2 . A unit as claimed in  claim 1 , in which the body is formed from a material selected from: fibreglass; wood; metal; plastics. 
     
     
         3 . A unit as claimed in  claim 1 , in which the unit comprises a generally flat jamming surface and an inclined back. 
     
     
         4 . A unit as claimed in  claim 1 , in which the unit is generally wedge shape in section. 
     
     
         5 . A unit as claimed in any preceding claim, in which the unit comprises a fixing flange. 
     
     
         6 . A unit as claimed in  claim 1 , in which the liner comprises a rippled or corrugated inner face. 
     
     
         7 . A unit as claimed in  claim 1 , in which the liner is textured. 
     
     
         8 . A system as claimed in  claim 1 , in which the liner provides an undulating inner jamming surface. 
     
     
         9 . A unit as claimed in  claim 1 , in which the liner is formed separately from and is attachable to the jamming surface. 
     
     
         10 . A unit as claimed in  claim 1 , in which the liner is bonded to the body. 
     
     
         11 . A unit as claimed in  claim 1 , in which the unit includes a flange for fixing to a climbing wall. 
     
     
         12 . A unit as claimed in  claim 1 , in which the unit comprises or can be associated with an end cap at either or both ends thereof. 
     
     
         13 . A crack climbing system comprising separate first and second units according to  claim 1 , the units are arrangeable with the inner jamming surface opposed to define a desired crack width. 
     
     
         14 . A climbing crack system according to  claim 13 , comprising: one or more central sections, the or each central section comprising separate first and second central units each including an inner jamming surface, the central units are arrangeable with the inner jamming surface opposed; a first end cap section comprising separate first and second end cap parts each including an inner jamming surface; and a second end cap section comprising separate first and second end cap parts each including an inner jamming surface. 
     
     
         15 . A climbing wall provided with one or more units according to  claim 1 .
