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.
2S 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.

The axle supporting means comprises an elongate tubular member 58 mounted on the hinge member 56 arranged to extend substantially parallel to an axis of rotation extending substantially perpendicular to and between the rail members 18. The axle 54 of the guide rail follower 24 has been lengthened to allow it to extend through both of the elongate tubular members 58 of the paired pivot connectors 22.
This gives each pivot connection 22 additional strength and yet allows standard hinged members to be used thereby keeping costs down and allowing a door manufacturer or installer to stock fewer types of hinge.
Each one of the door panels 20 comprises a plurality of door panel sections 26 each of which includes a top edge 60 and a bottom edge 62 and extends from the first side 46 of the door panel 20 to the second side 48 of the door panel 20. Each door panel section is arranged in end to end alignment like the door panels 20 with the top and bottom edges 60 and 62 of adjacent door panel sections 26 lying adjacent one another.
The door panels 20 comprise two or more standard sized overhead door panel sections 26 which are joined together by a pair of J-shaped channel members 66 one being arranged along each of the first and second sides 46 and of the respective door panel 20. Using standard sized door sections allows the door manufacturer or installer to build custom sized door panels 20 from standard sized components thereby reducing costs and reducing the required number of different parts.
The J-shaped channel members 66 are arranged to hold the plurality of door panel sections 26 in alignment relative to each other such that each of the _ $ _ door panel sections 26 is supported vertically by the J-channel 66 when the door 10 is in a fully closed position.

Each one of the pair of J-shaped channel members 66 is arranged at a respective one of the first and second sides of the door panel 20, and is arranged such that the plurality of door panel sections 26 is supported vertically by the bottom plate 82 when the door 10 is in the fully closed position, and such that the plurality of door panel sections 26 are held in alignment relative to each other by the leg and foot members 70 and 76 of the J-shaped panel 66.
Each door panel 20 includes fixing means 84 for fixing the top and bottom edges 60 and 62 of adjacent ones of the plurality of door panel sections 26 to one another. The fixing means comprise a plurality of plate or hinge members arranged to extend across the joint between adjacent door panel sections 26 and fasteners for fastening the hinge or plate members in place. The plurality of fixing means 84 are spaced apart across the door panel 20 between the first side 46 and the second side 48.
Referring to Figures 1 and 2 the counter weight door 10 also includes a first guide pulley 88 mounted adjacent the fist side 46 of the door, a first guide pulley mount 90 for mounting the first guide pulley 88 adjacent the first side of the _g_ door. A second guide pulley 92 is mounted adjacent the second side 48 of the door 10, and a second guide pulley mount 94 is provided for mounting the second guide pulley 92 adjacent said second side 48 of the door 10. A plurality of counter weights 96 are arranged adjacent the second side of the door 48 and provide a counter balancing force to the weight of the door. Connection means 97 are provided for connecting the plurality of counter weights 96 to each other and to the door 10.
First and second elongate members 98 and 100 are each fixed at a first end to the door 10 adjacent first and second sides thereof. The first elongate member 98 extends from the first side 46 of the door 10 over the first guide pulley 88 laterally across the door 10 and over the second guide pulley 90 to a second end 102. The second elongate member 100 extends from the second side 48 of the door 10 and over the second pulley 90 to a second end 104. The first and second elongate members 98 and 100 are connected to the connection means 97 adjacent the respective second ends 102 and 104 such that movement of the door 10 causes counter movement of the counter weights 96.
The door 10 when in the fully closed position lies in a plane extending substantially perpendicular to and between the substantially vertical guide rails 18.
Referring to 2, 10, and 11 the first mounting plate 106 is fixed to an outer edge 108 of the first guide rail member 18 adjacent to curved portion 40 of the guide rail 18 and parallel to the vertical and horizontal portions 32 and 34 of the guide rail 18.

The attachment plate 118 extends past one of the plate members 112 and includes a plurality of holes arranged therethrough. The holes 120 in the first pulley mount 90 are arranged to cooperate with holes in the first mounting plate 106 to receive fasteners therethrough thereby fixing the first pulley mount 90 on the guide rail 18.
Mounting the first pulley mount 90 on the guide rail 18 eliminates the need for mounting the pulley on the wall 14 of the building, and allows the pulley 89 to be more consistently and accurately aligned such that the cable 98 lies as close to the plane of the door 10 as possible.
Referring to 2, 8, 9, and 10 the door 10 also includes a mounting member 130 fixed to an outer edge of the second guide rail 18 adjacent to curved portion 40 of the guide rail member 18 and parallel to vertical and horizontal guide rails 32 and 34. The mounting member 130 extends forwards of the guide rail 18b towards the wall 14 of the building 16.
The second pulley mount 94 comprises a elongate attachment arm 132 which extends from a first end 134 to a second end 136 and has a plurality of holes 138 extending therethrough. The holes 138 are arranged along the attachment arm 132 to cooperate with holes arranged in the top of the mounting member 130. The holes 138 are arranged to receive fastener means 142 which fix the attachment arm to the guide rail 18. The attachment arm 132 as it extends from the first end 134 to the second 136 angles forwards and upwards from a point spaced rearwards from the second end 136. To a point 146 located nearer the second end 136.
A pair of parallel spaced apart members 148 and 149 each extending downwards from a first end 150 to a second end 152 or fixed to the attachment arm 132 at their first ends 150. The plate member 149 is fixed to the attachment arm 132 adjacent the second end 136 thereof. An axle member 154 extends between the plate members 148 and 149 and is arranged to lie parallel to the attachment arm 132. The second pulley 92 is mounted on the axle 154 perpendicular to the attachment arm 132 and such that it lies substantially in the plane of the door 10.
The pulley 92 is a double pulley for receiving both the elongate members 98 and 100. The plate member 149 arranged at the end of the attachment arm 132 includes at least one hole 156 therethrough. The hole 156 is arranged for cooperation with the fastener means which fix the spaced apart plate member to the wall 14 of the building.
The second pulley mount 94 is mounted on the mounting member 130 securing it to guide rail 18 such that the second pulley 92 and the cable 100 lie as close to the plane of the door as possible.
The pulley mounts 90 and 94 allow the pulleys to be easily arranged and secured above and to the side of the opening 12 in the wall 14 and to lie in line with the substantially horizontal guide rails 18. Mounting the pulleys 88 and directly on the guide rails helps the installer mount the pulleys such that their axis of rotation lies substantially perpendicular to the plane of the door 10. This helps ensure smooth operation of the pulleys 90 and 94 as the door 10 is opened and closed.
In an alternative arrangement the second pulley mount 94 may be mounted directly on the guide rail 18 securing it in line with the guide rail and allowing the second pulley 92 and the elongate cable 100 to lie as close to the plane of the door as possible. Further more the second pulley mount 94 may be fixed only to the guide rail or may be fixed to the guide wall and to the wall of the building to provide additional support.
While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
