Device adapted to mount a metal jamb or frame, more particularly a door jamb, into a wall opening

A device adapted to mount a metal jamb or frame, more particularly a door jamb 3 having a U-shaped cross-section into a wall opening, said device comprising a fixing plate 6 to be mounted against the reveal 2 of a wall opening and an adjustable bracket 8, connected to the fixing plate in a slidable and fixable manner. The fixing plate 6 consists of an oblong plate extending over almost the entire width of the reveal and comprises at each end relatively short side flanges 9 projecting from the wall, while the adjustable bracket 8 has a U-shape with two legs 14 embracing the wall in a mounted position said legs being engageable with the side flanges of the fixing plate, while said legs are also provided with means 16, 20 for receiving end flanges of a frame to be mounted.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a device adapted to mount a metal jamb or 
frame, more particularly a door jamb into a wall opening. 
2. Description of the Prior Art 
Various devices have been used in the art for mounting a jamb or frame with 
a substantially U-shaped cross-section, into a wall opening, that said 
jamb can be set on the reveal of said wall opening into an accurately 
vertical position. 
Such known devices frequently have a complicated construction, making 
mounting very time-consuming. 
SUMMARY OF THE INVENTION 
It is a main object of the present invention to overcome this shortcoming 
and to provide a device enabling a jamb or frame to be mounted and 
adjusted in a simple manner such a device can be manufactured 
inexpensively due to its simple construction. 
This is achieved according to the present invention. In the present 
invention the fixing plate of the respective device is formed by a oblong 
strip-shaped plate extending over almost the entire width of the reveal. 
At each end, relatively short side flanges project from the wall, each 
side flange being provided with a bore hole. The adjustable bracket is 
connected to said fixing plate in a slidable and fixable relation, having 
a U-shape with two legs embracing the wall in the mounted position. The 
legs are provided with slot-shaped openings for adjustably mounting the 
bracket to the side flanges of the fixing plate. The legs are further 
provided with receiving members for the receipt of a frame to be mounted. 
This type of construction has the advantage that the adjustable bracket can 
be easily mounted and positioned, so that the frame to be subsequently 
secured thereto assumes directly its proper position. 
According to the invention, the receiving members consist of an outwardly 
flanged lip formed on each free end of the legs. Outwardly directed 
pressed-in portions are provided in the legs at a certain distance from 
each lip, so that an end flange of a frame to be mounted can be locked 
between the lip and the pressed-in portions. 
Thus, a frame to be mounted can be pushed upon the adjustable bracket(s) as 
set, until its (their) end flanges snap into the space between the lip and 
the pressed-in portions. The frame is tightly connected to the adjustable 
bracket, due to its own resilient action. 
The features of the present invention which are believed to be novel are 
set forth with particularity in the appended claims. 
Many attendant advantages will be more readily appreciated as the same 
becomes better understood by reference to the following detailed 
description when considered in connection with the accompanying drawings 
in which like reference symbols designate like parts throughout the 
figures.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Referring now to FIG. 1 a wall 1 with a reveal 2 of a door opening is 
illustrated. In the opening there is a jamb 3 provided for a door 4 and 
mounted by means of a device 5 located on the reveal 2. The jamb 3 has a 
substantially U-shaped cross-section and comprises end flanges directed 
toward one another. 
Referring now to FIG. 2, as is particularly evident, the device according 
to the invention consists of a fixing plate 6 which can be mounted on the 
reveal 2 of a wall opening by means of screws 7, and of a U-shape 
adjustable bracket 8 connected to the fixing plate 6 in a slidable and 
fixable manner. 
The fixing plate 6 comprises an oblong strip-shaped element the length of 
which practically corresponds to the thickness of the wall 1, at each end 
comprising relatively short side flanges 9 projecting from the wall, each 
flange being provided with a bore hole 10. The central portion of the 
fixing plate 6 is provided with two slot-shaped openings 11, 11' extending 
in the longitudinal direction of the plate, provided for the screws 7. The 
fixing plate may also be provided with reinforcement ribs 12. 
The U-shaped adjustable bracket 8 likewise has the form of a strip and 
consists of a body 13 and two side legs 14, embracing the wall in the 
mounted position. Said body 13 is provided with openings 15, 15' roughly 
corresponding to the openings 11, 11' in the fixing plate 6, so that the 
screws 7 can be fitted without having to loosen the adjustable bracket 
from the fixing plate. The side legs 14 of the adjustable bracket 8 are 
provided on their free ends with an outwardly flanged lip 16. Both legs 14 
are also provided with a slot-shaped opening 17 extending in the 
longitudinal direction thereof, the surface along said opening being 
provided with a roughening 18 both on the outer and on the inner sides of 
said legs. The outside portions of the flanges 9 of the fixing plate 6 
which engage the inner side of the legs 14, are also provided with a 
corresponding roughening 1. The upper and lower longitudinal edges of the 
adjustable bracket 8 comprise reinforcement ribs 20 extending over the 
entire length of the bracket. The end portions of these ribs form, in 
conjunction with the lips 16, the receiving members on which the end 
flanges of a jamb 3 are to be mounted. 
Mounting jamb 3 proceeds in the following manner. Several fixing plates 6, 
properly spaced from one another, are secured to the reveal 2 of the wall 
opening by means of screws 7. Thereupon, the U-shaped adjustable 
bracket(s) 8 is or are connected to the fixing plates 6; secured thereto 
for instance by means of self-tapping screws 21 which engage the side 
flanges 9 through the bore holes 10 and successively pass through the 
slots 17 provided in the legs 14. Subsequently, the adjustable brackets of 
the various devices are secured after being properly positioned in 
relation to one another by means of the slots 17. The roughened portions 
18, 19 ensure that the U-shaped adjustable brackets 8 are tightly secured 
in relation to the fixing plates 6, so that they cannot move when the jamb 
3 is being mounted. The jamb 3 is pushed over the U-shaped adjustable 
bracket(s) 8 until the end flanges of the jamb 3 snap into the space 
provided between the lip 16 and the end portions of the reinforcement ribs 
20. Due to the resilient action of the frame itself, said end flanges 
remain solidly locked, thus precluding the need for additional fastening 
means. 
Both the fixing plate 6 and the U-shaped adjustable bracket 8 have a 
particularly simple construction and can be made from sheet iron in an 
easy and inexpensive manner. 
Although the present invention has been shown and described in connection 
with a preferred embodiment thereof, it will be apparent to those skilled 
in the art that many variations and modifications may be made without 
departing from the invention in its broader aspects. It is therefore 
intended to have the appended claims cover all such variations and 
modifications as fall within the true spirit and scope of the invention.
