  • Patent number: 5375383
    Abstract: A garage door frame has a pair of vertical frame members attached to each lateral end of a horizontal frame member. The door frame components can be transported to the construction or job site and assembled there to avoid the expense of welding at the manufacturer and to better accommodate job site specification and design changes. Alternatively, the components can be pre-assembled at the factory. Each vertical frame member is joined to the horizontal frame member with a unique connector which slidably inserts within the horizontal frame member and between side walls of a U-shaped portion of the vertical frame member. A combination of interlocking ribs and grooves formed in the frame members secures them together. First and second preferred embodiments of the invention are adapted for use with extension spring garage doors and torsion spring garage doors, respectively.

  • Patent number: 5240216
    Abstract: Novel angled flag brackets for use with tracks for sectional overhead garage doors are disclosed. The novel angled flag brackets of the present invention are uniquely designed to permit the vertical and horizontal tracks to be uniquely adjusted in both vertical and horizontal directions at the time of assembly and installation so that the assembled and installed tracks will be plumb, level or square. The novel angled flag brackets further permit end bearing plates of torsion spring systems to be directly mounted thereto when door jambs are too short so that the end bearing plates will not remain free-standing following installation.
