Appl. No.:

7/770233

Inventors:

Robert L. Day - Sun Valley CA

International Classification:

E06B 104

US Classification:

49504

Abstract:

A prefabricated door frame includes two vertical frame elements and a header element, each of channel shaped configuration with side flanges encompassing the wall at the edges of a wall opening. One of the vertical frame elements is secured by the aid of threaded fasteners passing through the jamb face of the frame element and into the rough frame member. Heads of the fasteners prevent movement of the frame element away from the rough frame member. After appropriate adjustment to plumb the frame element, cover plates are attached to the jamb face and overlie the screw heads thus to secure the frame element in its adjusted position. The header and other vertical frame element are positioned by the aid of registry clips inserted at the ends of the header element and the upper ends of the vertical frame elements. A jack screw captured behind the stop of the other vertical frame element reacts against the rough frame member to clamp the header element in place and thus determine the nominal spacing of the vertical frame elements. Another threaded fastener passes through the jamb face of the other frame element and into the rough frame member.

International Classification:

B25G 300

US Classification:

403 7

Abstract:

A ball joint comprises companion inner and outer hollow ball sections each comprising a major segment of a sphere.
