9 Claims. (Cl. -119 The present invention relates to a novel sliding door frame structure, and more particularly to a novel pockettype firameestructure.

An .object vof the present ,inventionis to provide a novel pocket-type sliding door frame structure which .may be essentially prefabricated at a factory (and shipped to .a building site in a knocked \down condition and which is constructed to facilitate easier and faster installation in a previously prepared rough opening in a wall structure of a building or the like.

.A more specific object .of the present invention is to provide a novel door frame structure having a header member and a plurality of jjamb members, which structure is adapted to enable thejamb members to be quickly, easily and securely connected to the header member without need for a workman doing the'installation work to apply or tighten fastening devices .such as screws, rivets, bolts or the like.

Another object of the present invention is to provide a novel pocket-type door frame structure of the above described type wherein thejjamb members are "secured to the header in a manner which provides 'arigid connection so as to improve rigidity of the u'ltimatewall structure and to obtain support for intermediate portions of the header member.

A Lfurtherob'jec't of the present invention is to provide a novel pocket-type door frame structure of the above described type,which is constructed so that upon assembly of individual 'jamb members with a previously installed horizontal header member, the ja'rnb members are automatically brought substantially into vertical plumb positions.

Still another object of the present invention "is to provide a novel 'door frame s'trucuire of the above described type which may easily be adapted for installation in'walls' of various thicknesses and/or for accommodating doors of various thicknesses.

Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings wherein:

Fig. "1 is an elevational view showing a pocket-type sliding door frame structure embodying the features of the present invention installed within a rough opening in a fram'ed wall'structure;

Fig. 2 is an enlarged fragmentary perspective view showing the manner in which the jamb meni'bersrarezconnected with the header member in accordance with the present invention;

Fig. .8 is a fragmentary sectional view showing the manner of assembling the modified jamb members of Fig. 7; and

Fig. 9 .is a fragmentary perspective view showing another modified form of the present invention.

Referring now more specifically to the drawings wherein like parts are designated by .the same numerals throughout the various figures, a door frame structure 10 incorporating the features of the present invention is shown fully installed within a rough opening 12 .in a wall structure 14 which is formed in the usual manner. The door frame structure 10 comprises a header member 16 which is adapted .to be secured in a horizontal position to upstanding studs 18 and 20 defining opposite sides of the rough opening 12. The frame also includes pairs of separate and cooperable jamb members 22-24 and '2628 which are detachably connectable to the header member in the manner described below so that the frame structure may be shipped to the buildingsite in a knocked down condition and then quickly and easily installed in the rough opening.

In the embodiment shown, .the header member 16 is in the form of an inverted steel channel having a length similar to but less than the distance between the studs 13 and 20 defining the opposite sides of the rough opening. Bracket members '30 and 32 are connected with opposite ends of the "header member '16 and have flanges adapted to be secured to the studs 18 and 20 by a plurality of nails 34 and 36 or the like. Preferably, these brackets are axially adjustably connected to the header member to adapt the header member "for installation in rough openings of various widths. This is accomplished by providing the bracket '30, for "example, with elongated slots 38 in its opposite sides through which connecting screws '40 extend. As will be understood, the header may be easily installed in a proper horizontal position by nailing one of the end bracketsto a stud at a previously marked height above the floor 42 and then levelling the header andina'iling the opposite end bracket to its associated stud. The end brackets are provided with sufficient holes for accommodating 'severalnails, and, if desired, the header may be initially secured by a single nail through each bracket .80 that any slight deviation from the proper horizontal position may be corrected by tapping one end of the header with a h'ammerprior to final securing by additional nails.

A depending track member 44 is secured within the header member by a plurality of screws 46. A door 48 is supported from this track member by apairof hangers 50 secured to the top edge of the door and having rollers '52 riding 'onthe track member.

The jamb members 22 and .24 respectively comprise similar elongated steel channels 54 and 56 which, in the embodiment shown, combine :with the header member 16 to provide the frame structure with an over-all thickness substantially equal :to .the Width of the studs 18 and Inorder to facilitate attachment of wall covering material such .as wallboard, plaster .l-ath or the like to the :jamb members, na-ilin g strips .58 and 60 of wood or the like are disposed within .the channels. A plurality of detents 62 and 64 are preferably struck inwardly from the sides of the channels 54 and.5.6 .for preventing .axial displacement of the nailing strips.

In accordance with a feature .of the present invention, a bracket 66 is secured to and preferably presassembled with the header 16 whereby the jamb members 22 and 24 may be easily, quickly and securely connected with the header. The metal bracket 66 comprises a base portion 63 adapted to be connected to the header by a plurality of screws '70, and a pair of end portions 72 and '74 which extend upwardly and outwardly from opposite sides of the header member. These end portions are respectfully provided with rectangular openings 75 and 76 adapted to receive upper end portions of the jamb members 22 and 24. The upper end portions '78 and of the jamb members respectfully have their opposite sides cut away as at 82 and 84 so that they may be inserted through the openings in the attachment plate or bracket while at the same time the terminal ends of the attachment plate do not project laterally beyond the outer surfaces of the main portions of the jamb members. Thus, the terminal ends of the attachment bracket will not interfere with the wall covering material secured to the jamb members.

It should be noted that the end portions 72 and 74 of the attachment bracket extend upwardly at a substantial angle from the horizontal, which angle, for example, may initially be about 45 as shown by the position of the end portion 74 in Fig. 3. Furthermore, the major length of each of the openings is such. that the opposite sides or flanges of the jamb member upper end portions 78 and 80 are closely retained by portions of the bracket defining opposite ends of the opening. These features tend to prevent the jamb members from shifting in planes parallel to the longitudinal axis of the header when the jamb members are fully assembled with the header. Thus. when the jamb members are applied to a horizontally positioned header member, they will automatically assume approximately vertical positions.

The minor width of the openings 75 and 76 is similar to but slightly greater than the width of the jamb member upper end portion side flanges. As a result the jamb members must be arranged in inclined positions as indicated by the jamb member 24 in Fig. 3 before their upper end portions can be inserted through the openings. Then when the jarnb members are swung by toward the header member and toward vertical positions, their upper end portions bind between inner and outer edges of the openings. Furthermore, the end portions of the attachment bracket or plate will be flexed downwardly as shown by the end portion '72 in Fig. 3 so that the inner and outer edges of the openings aggressively engage the iamb members and resist any axial movement of the jamb members to the opening. Thus. the connection between the iamb members and the header member is sufiiciently rigid and secure so that any force such as the weight of the door tending to bow the header member downwardly is transmitted to and at least partially supported by the jamb members whereby the header member may be formed from lighter weight and more economical material. Freferably, the inner edges of the openings 75 and 76 are located substantially in vertical alignment with the outer side surfaces of the header member as shown best in Figs. 3 and 4. Thus, the opposite sides of the header member serve as abutments limiting inward movement of the jamb members so that when the jamb mem bers are swung inwardly during assembly thereof, they are automatically located in substantially vertical positions.

Associated with the lower end of the jamb member 22 is a foot member 82 having a base plate 84 and upstanding tab 86 welded or otherwise secured to the iamb member. Apertures 88 are provided in the base plate through which nails or the like may be driven for securing the foot member and, thus, the lower end of the jamb 22 to the floor. A separate foot member 90 is connected with the lower end of the jamb member 24, which foot member has a base plate 92 provided with nail receiving apertures 94 and an upstanding tab 96 welded or other wise secured to the jamb members. A slot 98 is formed in the inner edge of the base plate 84 and a complementary tongue 100 projects from the inner edge of the base plate 92 and is adapted to enter the slot as shown in Fig. 6. Thus, after one of the jamb members has been properly located in a vertically plumb position and secured to the floor, the other jamb member may be automatically properly positioned by relatively moving the foot members 82 and 90 into abutting relationship with the tongue extending into the slot as shown in Fig. 6.

The above mentioned jamb members 26 and 28 are identical to the jamb members 22 and 24 and are adapted to be connected to the header by a bracket or plate member 102 which is identical to the attachment plate 66. It is also to be understood that the jamb members 26 and 28 are provided with separate foot members respectively identical to the foot members 82 and 90.

In order to adapt the frame structure for defining door openings of various widths, a plurality of sets of apertures 104 is provided in the header member for receiving the connecting bracket securing screws 70 at locations spaced along the header member. The bracket 66 will normally be assembled at the factory in the position shown adjacent nailing plates 106 and 108 of wood or the like which are secured to opposite sides of the header by a plurality of screws. This is the proper location for the majority of the door openings, but in the event a wider opening is desired, a workman may easily remove and relocate the attachment plate or bracket 66. The nailing plates 106 and 108 each have a thickness substantially equal to the thickness of the jamb members 22 and 24 respectively and are provided for enabling wall covering material to be nailed or otherwise secured to the header above the door opening.

Figs. 7 and 8 show a modified door frame structure which is similar to the construction described above as indicated by the application of identical reference numerals with the suflix a added to corresponding elements. This embodiment differs in that the opposite side flanges of the upper iamb member portions 78a and 80a are respectively provided with series of notches 110 and 112. These notches are adapted to receive outer terminal end sections of the attachment bracket or plate 66a when the upper ends of the jamb members are inserted through the openings and swung toward vertical positions so that the jamb members and the attachment plate or bracket are positively interlocked to restrain movement of the jamb members out of vertical positions and to provide an even more positive support for the intermediate portions of the header member.

Another advantage of the structure of this invention is illustrated in Figs. 7 and 8. More specifically, the frame structure is adapted easily to be modified for installation in a wall having a thickness greater than the usual thickness when the wall is framed with standard two-by-four studs. This may be accomplished by replacing the standard bracket or plate 66 with a longer plate 66a so that the jamb members are spaced the desired distance laterally from the header member to mcrease the overall thickness of the wall. Of course, the lower ends of the jamb members will also be spaced farther apart, but it should be noted, that the interlocking tongue and slot of the foot members will still enable the lower ends of the jamb members to be quickly and easily aligned as shown in Fig. 7. The nailing plates on the header member above the door opening may be easily adapted for a thicker wall' structure merely by securing wooden shim members or the like thereto. It is to be understood that the embodiment of Figs. 1 through 6 may be adapted for various wall thicknesses by substituting attachment brackets or plates of different lengths and that the embodiment of Figs. 7 and 8 may be adapted for a wall having a standard thickness by substituting a shorter attachment bracket or plate.

In Fig. 9 there is shown another modified form of the present invention which is essentially identical to the structures described above as indicated by the application of identical reference numerals with the suffix b added to corresponding elements. In this embodiment pairs of spaced tabs 114 and 116 are respectively struck from opposite sides of the header member 16b. The tabs 114 are disposed for snugly embracing the jamb member 22b when it is moved into its vertical position for even more securely retaining the jamb member against movement out of the proper vertical position in a plane parallel to the longitudinal axis of the header member. The tabs 116 are disposed for snugly embracing and similarly restraining the jamb member 24s. It will be appreciated that the header member 16b may be provided with similar tabs for restraining jamb members, not shown, corresponding to the above described jamb members 26 and 28.

While the preferred embodiments of the present invention have been shown and described herein, it is obvious that many structural details may be changed without departing from the spirit and scope of the appended claims.
