Garage door frame

摘要

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.
