Hinge Pivot Mount Assembly

Abstract

A parallel opening hinge includes tracks pivotally connected crossing links, wherein each pair of crossing links is mounted to the tracks via a fixed pivot and a movable pivot in each track. A connector joins two movable pivots in a track such that the movable pivots move together. Improved opening of a parallel opening vent can thereby result. A pivot mount for a link of the hinge includes a support block and a pivot pin engaging the support block, wherein the pivot pin includes a cam surface for abutting a link of a hinge in use to move the link relative to the support block.

1 . A pivot mount for a link of a hinge, the pivot mount comprising a support block and a pivot pin engaging the support block, wherein the pivot pin includes a cam surface for abutting a link of a hinge in use to move the link relative to the support block. 
     
     
         2 . A pivot mount as claimed in  claim 1 , wherein the pivot pin has a shaft for engaging the support block. 
     
     
         3 . A pivot mount as claimed in  claim 2 , wherein the cam surface is circular and offset from the axis of the shaft. 
     
     
         4 . A pivot mount as claimed in  claim 3 , wherein the diameter of the circle defining the cam surface is larger than the diameter of the shaft. 
     
     
         5 . A pivot mount as claimed in  claim 1 , wherein the pivot pin includes a head for retaining a link on the block, in use. 
     
     
         6 . A pivot mount as claimed in  claim 5 , wherein the head is shaped to receive a tool to rotate the pivot pin. 
     
     
         7 . A hinge comprising:
 a track;   a link;   a pivot mount connecting the link to the track, wherein the pivot mount includes a support block and a pivot pin engaging the support block, and wherein the pivot pin includes a cam surface for abutting the link operable therewith to move the link relative to the support block.   
     
     
         8 . The hinge as claimed in  claim 7 , wherein the hinge is operable with a vent.
