DETAILED DESCRIPTION
Referring to Figure 1, the improved counter weight door is shown generally at 10. The improved counter weight door 10 is for use in an opening 12 in the wall 14 of a building. The improved counter weight door 10 comprises a pair of spaced apart guide rail members 18, a plurality of door panels 20, a plurality of pivot connection 22, and a plurality of guide rail followers 24.
Referring to Figure 1, 10 and 11 the pair of spaced apart guide rail members 18 are arranged with one on each side of the opening 12 in the wall 14.
Each one of the pair of rail members 18 includes a substantially vertical portion 28 which extends upwards from a bottom end 30 to a top end 32 and which is fixed to the wall 14 adjacent sides of the opening. A substantially horizontal portion 34 is arranged adjacent the top end 32 of the substantially vertical portion 28 and extends rearwards into the building from a front end 36 to a rear end 38. A curved portion 40 extends upwardly and rearwardly between the top end 32 of the substantially vertical portion 28 and the front end 36 of the substantially horizontal portion 34.
The plurality of door panels 20 each extend from a top end 42 to a bottom end 44 and from a first side 46 adjacent a first one of the pair of rail members 18 to a second side 48 adjacent a second one of the pair of rail members 18.
The plurality of door panels 20 are arranged in end to end alignment with the top and bottom edges 42 and 44 of adjacent door panels 20 adjacent one another.
The plurality of pivot connections 22 are arranged to pivotally connect each one of the plurality of door panels 20 to the door panels lying adjacent.
Each one of the plurality of pivot connection 22 is pivotal about an axis of rotation 50 extending substantially perpendicular to and between the two spaced rail members 18.
The plurality of guide rail followers 24 comprise a guide roller for engaging a respective one of the spaced apart guide members 18 and an axle member 54 for rotatably mounting the guide roller 52 at the pivot connection 22.
In order to accommodate the additional weight of a large counter weight door 10 the arrangement of the pivot connections 22 and the guide rail followers 24 has been modified. A pair of pivot connections 22 comprises a pair of hinge members 56 mounted side by side at the joint between adjacent top and bottom edges 42 and 44 of adjacent ones of the plurality of door panels 20.
