Abstract
Elements for forming a frame such as a metal door frame having spring clips by which a head rail and side members are connected, and a spacer or tie bar by which the elements can be stabilized during erection of the frame in a door way.
Claims11
A metal door frame for defining a doorway through an opening in a wall, comprising:
- a pair of door jambs and a head rail, each of said jambs and said head rail having a substantially identical channel-shaped cross-section comprising opposed flanges connected by a web, said flanges being directed away from said opening towards the body of said wall;
- and
- a bracket secured to the free end of the head rail, said bracket having a body of L-shaped cross-section, one limb of said L-shaped body being secured to the head rail and the other limb of said L-shaped body extending upwardly from the end edge of the web of said head rail in a plane at substantially right angles to the length axis of the head rail, said bracket further incorporating a spring clip leg having an upper portion integrally continuing from the upper end of said upward extending bracket limb, said spring clip leg extending convergently downward from the upper edge of said upward extending bracket limb close along the outboard face of latter for snugly receiving and resiliently gripping therebetween the upper edge portion of the web of the adjacent jamb, thereby securing said head rail on said jamb, said upward extending limb and spring clip leg including opposed portions spaced not more than the thickness of the web of the adjacent jamb, said spring clip leg being resiliently bendable away from said outboard face of said upward extending body limb.
A metal door frame for defining a doorway through an opening in a wall, comprising:
- a pair of door jambs and a head rail, each of said jambs and said head rail having a substantially identical channel-shaped cross-section comprising opposed flanges connected by a web, said flanges being directed away from said opening towards the body of said wall;
- and
- securing means secured to the head rail and including a bracket at the free end thereof, said bracket having a body of L-shaped cross-section, one limb of said L-shaped body being secured to the head rail and the other limb of said L-shaped body extending upwardly from the end edge of the web of said head rail in a plane at substantially right angles to the length axis of the head rail, said upward extending bracket limb fixedly supporting a spring clip leg extending convergently downward from the upper edge of said upward extending bracket limb close along the outboard face of the latter for snugly receiving and resiliently gripping therebetween the upper edge portion of the web of the adjacent jamb, thereby securing said head rail on said jamb, the end edge of the head rail being contoured to the cross section of said jamb to snugly receive the jamb, the jamb extending substantially to the tops of the flanges of the head rail, said head rail flanges having an inturned lip at the upper end of said jamb, said upward extending limb of said bracket being the height of said head rail flanges.
A metal door frame for defining a dorway through an opening in a wall, comprising:
- a pair of door jambs and a head rail, each of said jambs and said head rail having a substantially identical channel-shaped cross-section comprising opposed flanges connected by a web, said flanges being directed away from said opening towards the body of said wall;
- and
- securing means secured to the head rail and including a bracket at the free end thereof, said bracket having a body of L-shaped cross-section, one limb of said L-shaped body being secured to the head rail and the other limb of said L-shaped body extending upwardly from the end edge of the web of said head rail in a plane at substantially right angles to the length axis of the head rail, said upward extending bracket limb fixedly supporting a spring clip leg extending convergently downward from the upper edge of said upward extending bracket limb close along the outboard face of the latter for snugly receiving and resiliently gripping therebetween the upper edge portion of the web of the adjacent jamb, thereby securing said head rail on said jamb, said spring clip leg being the outboard one of two opposed, and upper edge joined, legs of a U-cross-section spring clip which straddles said upward extending bracket limb and including a snap fit connection means securing the inboard one of said spring clip legs to said upward extending bracket limb for positively preventing separation therebetween upon insertion of said jamb web upward between said bracket and outboard spring clip leg.
