Guide track assemblies and mounting brackets for upward acting doors

In an upward acting door, opposed guide track assemblies for guiding movement of said door between open and closed positions, and opposed mounting brackets for supporting at least portions of said guide track assemblies, respectively, said brackets each including:

• a first flange for mounting said bracket on a vertical wall adjacent a guide track assembly;
• an integral support part extending substantially normal to said first flange and including a distal flag portion having plural elongated slots formed therein for receiving fasteners for connecting first and second track sections of said guide track assembly to said bracket, respectively;
• and
• plural spaced apart mounting tabs extending from one side of and coplanar with said first flange and operable to be engaged by fastener means for securing said bracket to said wall.

In an upward acting door, opposed multisection guide track assemblies for guiding movement of said door between open and closed positions, and opposed mounting brackets for supporting at least portions of at least two separate sections of said guide track assemblies, respectively, said brackets each including:

• a first flange for mounting said bracket on a vertical wall adjacent a guide track assembly;
• an integral support part extending substantially normal to said first flange and including a bearing bore formed therein for supporting bearing means for a shaft of a counterbalance mechanism for said door, and a distal flag portion having plural openings formed therein for receiving fasteners for connecting said two separate sections of said guide track assembly to said bracket, respectively;
• plural mounting tabs formed integral with and coplanar with said first flange for connecting said bracket to support structure;
• a second flange formed integral with said first flange and extending substantially normal thereto and spaced from said support part for connection to a counterbalance mechanism for said door;
• and
• said bracket is formed from a metal plate which is folded along a first fold region to form said first flange and said support part and is folded along a second fold region to form said second flange integral with said first flange.
