Description




FIELD OF THE INVENTION




The present invention relates to a coupling for mounting a door frame in a wall opening including anchoring clips mounted on one of the frame and wall and retaining clips mounted on the other of the frame and wall. The anchoring and retaining clips engage to secure the frame in the wall opening. More particularly, the present invention relates to a coupling wherein the anchoring clips are identical and have resilient cantilever portions and wherein the retaining clips are identical and have angled sections engaged by the cantilever portions.




BACKGROUND OF THE INVENTION




Conventional building industry practice uses prefabricated door frame assemblies which are manufactured at a manufacturing facility and then transported to a remote location for installation. This assembly includes a frame as well as a pre-hung door. The door frame includes a header jamb assembly for the top of the doorway opening in a wall and latch and hinge jamb assemblies for the sides of the doorway opening in the wall. To accommodate for variations in the thickness of the wall in which a door is located, the frame is adjustable to accommodate these wall thicknesses. Additionally, the frame should be adaptable to wide variety of uses, including the addition of a screen or storm door and the addition or omission of exterior trim.




A typical frame of this type is disclosed in U.S. Pat. No. 5,187,898 to McKann, entitled Adjustable Door Frame, the subject matter of which is hereby incorporated by reference. This frame is secured to the wall in the doorway opening by screws passing through the frame outside of and adjacent to the opening, as well as by screws passing through the portion of the frame inside the doorway opening and into the wall part defining the doorway opening. To provide a secure connection, the screws are within the normal field of vision and provide an unsightly appearance. Additionally, such screws require the use of considerable labor time by skilled installers.




Clip systems have been used for securing door frames in position. Typical clip systems are disclosed in U.S. Pat. No. 3,788,019 to Kiselewski, U.S. Pat. No. 3,545,135 to Lieber, U.S. Pat. No. 3,320,705 to Downing and U.S. Pat. No. 4,510,722 to van Wieringen.




However, these conventional clip mounting systems for door frames are not adequately simple and inexpensive to use and manufacture.




SUMMARY OF THE INVENTION




Accordingly, an object of the present invention is to provide a coupling for mounting a door frame in an opening and a door frame assembly including a mounting coupling which can be easily and economically manufactured and installed.




Another object of the present invention is to provide a coupling for mounting a door frame in an opening in a wall and a door frame assembly which eliminates screws in the normal field of vision.




Yet another object of the present invention is to provide a coupling for mounting a door frame and a door frame assembly which is rugged and of sturdy construction, and facilitates rapid installation.




The foregoing objects are basically obtained by a coupling for mounting a door in an opening in a wall, comprising substantially identical first and second anchoring clips and substantially identical first and second retaining clips. Each anchoring clip includes a base mounting portion and a resilient cantilever portion extending at a non-perpendicular angle from the base mounting portion. The two anchoring clips are oriented opposite to one another. Each retaining clip has a base mounting section and an angled section extending in a cantilever manner from its base mounting section. The two retaining clips are oriented in mirror image to one another such that the cantilever portions respectively engage the angled portions of the first and second retaining clips.




By forming the coupling in this manner, the anchoring clips and retaining clips can be inexpensively and easily formed from sheet metal. The manufacturing costs are substantially reduced by the two anchoring clips being identical and the two retaining clips being identical. In this manner, only two, relatively simple parts need to be manufactured and supplied for forming the coupling. The simple forms and identical constructions of the two anchoring clips and of the two retaining clips also simplify and facilitate the installation.




With these clips, the door frame can be retained and located simply within the doorway opening by snapping it into place. Any additional screws which may be necessary would be located at the bottom and/or top ends of the hinge and latch jambs, well away from the normal field of vision. Further, the clips greatly simplify the installation by eliminating the number of screws that would otherwise be necessary for securing the door frame within the doorway opening in a wall.




Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to FIGS.


1





4


, frame assembly


10


according to a first embodiment of the present invention comprises a door frame


12


, a door


14


pre-hung within frame


12


, and two snap-in couplings


16


. Each snap-in coupling comprises two wall anchoring clips


18


and


20


and two steel frame retaining clips


22


and


24


.




Door frame


12


includes a hinge jamb


26


, a latch jamb


28


and a header jamb


30


. The header jamb extends between and connects the hinge jamb and the latch jam. This frame assembly is mounted within doorway opening


32


in a wall


34


.




Wall


34


, door


14


and door frame


12


can be of any conventional form. For example, the wall can include wood studs


36


on which dry wall panels


38


and


40


mounted. Dimensional variations in the studs and dry walls, as well as the assembly thereof, produce variations in the thickness of the entire wall, i.e., between the oppositely directed surfaces of the two dry wall panels.




Each of the jambs is formed of two members forming a jamb part


42


and a closure part


44


. The parts of each jamb are constructed as disclosed in U.S. Pat. No. 5,187,898 incorporated by reference hereinabove. Thus, the details of the form of each of the jambs and parts thereof are not further described in detail.




In the jambs, the flange sections


46


can be planar as illustrated, or can be suitably contoured to provide an ornamental appearance (e.g., of wood moldings).




Since each of the wall anchoring clips


18


and


20


are identical, only one will be described in detail. Wall anchoring clip


18


comprises a base mounting portion


48


and a resilient cantilever portion


50


. The base mounting portion includes two substantially perpendicular segments


52


and


54


coupled along a bend


56


. Segment


54


is essentially planar and is mounted on wall


34


outside of doorway opening


32


, but adjacent to the doorway opening. Base segment


52


comprises an inner part


58


adjacent bend


56


and an outer part


60


remote from the bend. The inner and outer parts are offset in parallel planes in direction of base segment


54


, and are connected by a joining part


62


extending generally parallel to but spaced from base segment


54


. Joining part


62


is connected to the inner and outer parts along substantially 90 degree bends.




Cantilever portion


50


is formed from a section of base segment


52


by being cut and bent therefrom. The outer periphery of the cantilever portion is generally rectangular. One of its longer edges is connected to a segment


52


along a bend line


64


. The cantilever portion is bent relative to the base segment


52


along bend or hinge line


64


, such that the cantilever portion extends in a plane which is at a non-perpendicular, acute angle relative to the base segment


52


and at a non-perpendicular, obtuse angle relative to base segment


54


.




With the offsetting of the inner and outer parts


58


and


60


, bend


56


and bend line


64


will be spaced from the wall by the same distance as the offset, when outer part


60


is engaged with the wall surface defining doorway opening


32


. In this manner, the entire cantilever portion is spaced from the wall to allow greater movement thereof, and is spaced closer to the respective retaining clip on the frame to facilitate and to ensure proper engagement therewith. The proper placement of the cantilever portion within the doorway opening is set by the engagement of base segment


54


with the wall outer surface outside of but adjacent to the doorway opening.




Holes


66


extend through base segment


54


and outer part


60


. These holes receive fasteners, preferably in the form of nails


68


. The nails extend through the holes and into the walls to secure the wall anchoring clips in position.




Since each of the wall anchoring clips is identical, clip


18


is inverted and opposite relative to clip


20


. Cantilever portions


50


of clips


18


and


20


are both located in and extend into doorway opening


32


. In this manner, the two wall anchoring clips


18


and


20


can be identically configured so that only one part need be manufactured, with the installer only arranging them in opposed and inverted manners, such that each anchoring clip performs properly.




Each of retaining clips


22


and


24


are identical. Each retaining clip comprises a base mounting section


70


and an angled section


72


. Sections


70


and


72


are connected along a 90 degree bend


74


such that the two sections are substantially perpendicular.




The base mounting sections of each retaining clip are affixed to an outer surface (i.e., a surface facing the wall) of an inside section


76


of jamb part


42


or closure part


44


of each of the latch jamb and hinge jamb. Preferably, this attachment is accomplished by spot welding. With base mounting sections fixed on the outer surfaces of the jamb part inside sections, the angled section


72


extend parallel to the longitudinally axis of the jamb and perpendicular to the door frame insertion directions.




Door


14


is pre-hung on hinge jamb


26


by hinges


78


. The hinges allow the door to open and close in a pivotal and conventional manner. Suitable and conventional latches are provided on the door and the latch jamb.




The door assembly is manufactured at a manufacturing facility with the retaining clips affixed to the jambs as described above. The wall anchoring clips are provided with the assembly but are separable therefrom. At the remote, door installation site, the retaining clips are mounted in the doorway opening, as illustrated and described above. Once the wall anchoring clips are in place, the jamb parts and closure parts of the hinge jamb, the latch jamb and header jamb are installed from opposite sides of the doorway opening to engage in an adjustable manner.




As the jamb parts and closure parts are installed, the angled sections of the retaining clips engage the cantilever portions of the wall anchoring clips causing them to be pivoted or moved in an outward direction as the angled sections ride up toward the free ends of the cantilever portions. Once the angled sections pass the beyond the free ends of the cantilever portions, the cantilever portions will snap back outwardly to engage the angled sections adjacent the base mounting sections of the retaining clips, locking the jamb and closure parts in position.




Suitable fasteners, such as screws, can be mounted out of the normal line of sight of the door i.e., adjacent the top and bottom ends of the latch jamb and hinge jamb, particularly through the member extending into the doorway opening to further secure frame assembly in place. Locating the screws in this manner, out of the normal line of sight, will provide a secure connection, while minimizing the number of screws that need to be installed and without adversely affecting the overall appearance of the door frame assembly.
