Coping Cleat and System for Roof Blocking Unit

Abstract

A cleat for use with a roof blocking unit has an integral leaf spring formed as a bend in a web intermediate its front and rear ends with a front side extending downward from the front end and a rear side extending downward from the rear end. In a coping unit, a diverter component defines a channel and is mounted over the cleat. The channel is disposed at an acute angle relative to the cleat web. In a coping assembly installation, a fluid impermeable membrane is disposed over the top of a roof blocking unit with the cleat mounted over the membrane and the diverter component mounted over the cleat. A pair of coping caps is disposed over the cleat and diverter in an offset arrangement with the channel beneath adjacent coping cap edges. The spring leaf biases the caps with a hook-like flange in engagement with a cleat flange.

What is claimed is: 
     
         1 . A cleat for a coping assembly for use with a roof blocking unit, comprising:
 a web having opposed front and rear ends;   a front side integrally extending from the front end to an outwardly extending distal flange;   a rear side integrally extending from the rear end to an outwardly extending distal flange; and   a first integral spring leaf formed from a bend in and extending from said web intermediate the front and rear ends in a direction opposite from the front and rear sides.   
     
     
         2 . The cleat of  claim 1 , wherein said spring leaf defines a plane that lies at an acute angle relative to the web. 
     
     
         3 . The cleat of  claim 2 , wherein the spring leaf includes a bend at the distal portion of the leaf. 
     
     
         4 . The cleat of  claim 2 , wherein the plane defined by the spring leaf lies at an angle of between approximately 15° and approximately 60° relative to the web. 
     
     
         5 . The cleat of  claim 1 , comprising a second integral spring leaf extending from said web at the same approximate angle relative to the web as the first spring leaf. 
     
     
         6 . The cleat of  claim 5 , wherein the second integral spring leaf extends from the web in the same relative direction as the first integral spring leaf. 
     
     
         7 . The cleat of  claim 5 , wherein the second integral spring leaf extends from the web in the opposite relative direction from the first integral spring leaf. 
     
     
         8 . The cleat of  claim 1 , wherein said spring leaf is formed as a cut in a portion of said web and upward bending of said portion. 
     
     
         9 . The cleat of  claim 8 , wherein said leaf is substantially rectilinear formed by a substantially U-shaped cut in the web defining an open end and bending along a substantially linear portion of the web at the open end. 
     
     
         10 . The cleat of  claim 1 , wherein the front end of the web transitions to the front side in a compound bend defining a vertex opposite the front side distal flange. 
     
     
         11 . The cleat of  claim 1 , wherein the web defines a plane that is substantially perpendicular to the front and rear sides. 
     
     
         12 . The cleat of  claim 1 , wherein said spring leaf defines a plane that lies at an angle of approximately 30° relative to the web. 
     
     
         13 . A coping unit for a roof blocking unit comprising:
 a cleat comprising a web having opposed first and second ends, a front side integrally extending from the first end to an outwardly extending distal flange, a rear side integrally extending from the second end, and an integral spring leaf extending from said web in a direction opposite from the front and rear sides; and   a diverter component comprising a central panel forming a diverter channel with a front end and a rear end, a front panel integrally extending from said front end, a rear panel integrally extending from said rear end; wherein   said diverter component is mounted over said cleat and said front panel engages said front side in a substantially surface-to-surface relationship, said rear panel engages said rear side in a substantially surface-to-surface relationship with the spring leaf biasing the central panel in the direction opposite from the front and rear sides, and said channel is disposed at an acute angle relative to said web.   
     
     
         14 . The coping unit of  claim 13 , wherein the channel is angled downward toward the rear side of the web. 
     
     
         15 . The coping unit of  claim 13 , wherein the first end transitions to the front side via a compound bend defining a vertex opposite the distal flange. 
     
     
         16 . The coping unit of  claim 15 , wherein the front panel extends from said front end via a bend that mates substantially with the vertex. 
     
     
         17 . The coping unit of  claim 13 , wherein the diverter channel is defined by a central web extending between opposite lateral edges, each lateral edge being bent in the direction opposite from the rear and front panels. 
     
     
         18 . The coping unit of  claim 13 , wherein the diverter component is substantially rigidly attached to the cleat in the mounted configuration without an external fastener. 
     
     
         19 . The coping unit of  claim 13 , wherein the diverter component front panel includes a distal flange disposed and angled to substantially abut the cleat first end flange. 
     
     
         20 . A coping assembly installation comprising:
 a roof blocking unit having a top surface extending between front and rear faces;   a fluid impermeable membrane disposed over said top surface;   a cleat mounted over said membrane and secured to said wall, the cleat having an integral spring leaf extending away from said top surface and a lower flange;   a diverter component mounted over said cleat and forming a drain recess disposed at an acute angle relative to said top surface; and   a pair of coping caps each having a lower hook-like flange and extending transversely between opposite edges disposed over said cleat and said diverter component in an offset arrangement, such that said drain recess is disposed substantially beneath adjacent edges of the coping caps, said spring leaf biasing said caps away from said top surface to urge the lower hook-like flange in each cap into engagement with the cleat flange.
