Batten riser

Abstract

A batten riser ( 10 ) is inserted into the overlap ( 11 ) between a batten ( 3 ) and a supporting member which can be a rafter ( 4 ), or a sheet of plywood ( 8 ) which covers the rafters. The battens support tiles ( 2 ) of a roof ( 1 ). The batten riser ( 10 ) has a flange ( 16 ) to assist maintaining the batten riser in position prior to securing the batten to the rafter by means of a nail ( 6 ). In addition, the batten riser has a series of ribs ( 20 ) on its underside. The spaces ( 21 ) between adjacent pairs of ribs both break water retaining capillary attractions and constitute drainage channels to permit water to drain away.

1 . A batten riser for a roof having a slope, said riser being of substantially planar conformation and sized for insertion between a supporting member and a roof batten which extends above said supporting member, which extends across the slope, and which supports a plurality of tiles arranged in rows to form said roof, wherein said batten riser includes an upwardly extending flange shaped to abut an upslope edge of said batten and said batten riser further includes a base having a plurality of spaced apart downwardly directed ribs with an opening between each pair of adjacent ribs forming a corresponding water drainage passage.  
   
   
       2 . The batten riser as claimed in  claim 1  and including a substantially centrally located aperture through which can pass a fastener shank, which extends from said batten into said support member.  
   
   
       3 . The batten riser as claimed in  claim 2  wherein said aperture divides said ribs into two groups, one located upslope of said aperture and the other located downslope of said aperture.  
   
   
       4 . The batten riser as claimed in  claim 3  wherein the number of ribs in said first group equals the number of ribs in said other group.  
   
   
       5 . The batten riser as claimed in  claim 4  wherein each said rib has a substantially rectangular transverse cross-section.  
   
   
       6 . The batten riser as claimed in claim I wherein said support member comprises a rafter.  
   
   
       7 . The batten riser as claimed in claim I where said support member comprises a sheet covering at least one rafter.  
   
   
       8 . A method of draining condensation from between battens and a support member therefor, supporting a roof having a slope, and extending across the slope, said method comprising the step of: 
 (i) inserting a batten riser of substantially planar configuration between the batten and said support member,    (ii) abutting an upwardly extending flange of said batten riser with an upslope edge of said batten, and    (iii) forming at least one water drainage passage between said batten and support member by a plurality of spaced apart ribs which are directed downwardly from a base of said batten riser.    
   
   
       9 . The method as claimed in  claim 8  including the further steps of: 
 (iv) forming a substantially centrally located aperture in said batten riser, and    (v) driving a fastener shank through said batten, through said aperture and into said support member.    
   
   
       10 . The method as claimed in  claim 9  including the further step of: 
 (vi) positioning said aperture to divide said ribs into two groups.    
   
   
       11 . The method as claimed in  claim 10  including the further step of: 
 (vii) forming each said rib with a substantially rectangular transverse cross-section.    
   
   
       12 . The method as claimed in claimed in  claim 8  including the further step of: 
 (viii) inserting said batten riser between said batten and a rafter.    
   
   
       13 . The method as claimed in  claim 8  including the further step of: 
 (ix) inserting said batten riser between said batten and a sheet covering at least one rafter.
