JOSEPH RASKIN ATZUENEY Patented Mar. 18, 1952 UNITED STATES PATENT OFFICE DOORFRAME Joseph Ra'skin, Brooklyn, Y. Application May 29, 1948, Serial No. 3 .5119
This invention relates to aperture frames and more particularly to prefabricated metallic door frames.
I One object of the invention is a simple prefabricated aperture frame suitable for. industrial applications.
A further object of the invention is to provide a simple prefabricated aperture frame which may be readily assembled without the aid of special tools or machinery.
Still another object of the invention is a prefabricated aperture frame which may be installed with a minimum of alignment checks.
v The invention also has for an object a method of producing and assembling the aperture frame.
To these and other ends, the invention consists in the construction, arrangement, and usage for the attainment of the above stated objects.
These and other objects of the invention and the means of their attainment will be more apparent from the following detailed description taken in connection with the accompanying drawings illustrating one embodiment by which the invention may be realized and in which:
Fig. 1 is a view in front elevation showing the door frame of this invention and the relationship of the structural members.
Fig. 2 is a view in side elevation showing the door frame and the relationship of the structural members.
Fig. 3 is a section view in side elevation in the plane indicated by the line 3-3 of Fig. 2 looking in the direction of the arrows.
Fig. 4 is a fragmentary isometric View showing a typical member joint in the assembled but unlocked position.
Fig. 5 is a fragmentary isometric view showing an alternative construction, in unlocked and disassembled condition.
Fig. dis a fragmentary isometric view of the alternative construction shown in Fig. 5, assembled but unlocked.
With reference to the drawings, similar reference characters refer to similar parts throughout.
Referring now to Figs. 1, 2, 3, and 4, a formed sheet metal structural member I0 is supported by two vertical formed sheet metal structural member jambs i2 and I3. Supporting plates M and i5, each provided with two formed slots it, are rigidly fastened by spot welds, screws, bolts, rivets, or other means, to the inside of the upper end of surfaces l1 and it of the vertical member .jambs l2 and E3. The vertical member jamb I2 is cut at an angle of forty-five degrees from the surface i8, as at IE, to form one half of the door frame corner joint.
The structural member l0 containsinsert tabs it which are. fitted into the formed slots 16 of the supporting plate IA. The ends of the formed structural member I'll, with the exception of the insert tabs 20, are cutsquare and butt up against the supporting plates. [4, and 15 for additional strength and rigidity-when assembled.
The vertical member jamb l2 contains insert tabs '22 which are positioned for alignment with the formed slots 24, which are located in surface 33 of the structuraljmemb'ejr H1, After locating the four insert tabs '20 and 22 in their respective formed slots l6 and 24, the insert,tabIS. 20 are deformed upward against the supporting. plate is thereby effectin a tight, joint, betweenthe square end of the structural member ['0 and the supportingplate M, The insert tabs 22 are then deformed downward and outwardja'gainstsurface 38 of the structural member It! thus effecting a tight joint between the upper inner portion I!) of the vertical member jamb l2 and the, formed structural member It. The vertical member jamb i3 is fastened to the structural member Ill in a like manner.
A tread spacer 26 is employed to effect parallelism of the two member jambs I2 and I3. An angle plate 28 is positioned and firmly secured as by spot welds, bolts, screws, or other suitable means to surface 40 of the vertical member jamb 2. The horizontal portion 36 of the angle plate 28 extends inwardly and contains a cutout insert tab 39 which is mutually perpendicular to the two surfaces of the angle plate 28. A similar angle plate 29 is fastened to the vertical member jamb l3. An angle bar 32, located in an inverted position (see Fig. 2), is formed with slots 34 which are located along the angle edge and are positioned for alignment with the cutout insert tabs 36. After assembly of the angle plates 28 and 29 and the angle bar 32, the cutout insert tabs 30 which extend through the formed slots 34, are deformed downward over the angle bar 32. The angle bar 32, if desired, may be removed after the door frame has been properly positioned.
Referring now to Figs. 5 and 6, an alternative method of joining the structural members I I0 and H2 is illustrated. Insert tabs 44 are positioned on the structural member I Ill for alignment with the formed slots 46 which are located in the upper surface 4| of the member jamb I [2. In like manner, insert tabs 42 are located on the upper end of the vertical member jamb H2 for alignment with the formed slots 48 which are located in surface 55) of the structural member H0.
With the exception of the insert tabs 44, the
ends of the structural member I H] are cut square and butt up against the inner surface of the vertical member jamb H2 when assembled. The upper inner portion of the vertical member jamb I I2 is cut at a forty-five degree angle to form the fitted joint.
Once again, the insert tabs t2 and 54 are inserted in their respective formed slots 46 and 48. The insert tabs 42 are then deformed downwardly and outwardly against surface 50 while the insert tabs 44 are deformed upwardly and inwardly against the outside of surface 4|. In this manner, an efiective joint of the formed structural members H9 and 1 I2 is produced.
By means of either of these two unique methods of forming an aperture frame corner joint, a considerable misalignment of members cannot cause a clear unsightly'space to appear at the joint. At the same time, this construction affords the maximum of rigidity and strength while still retaining the simplicity of assembly.
Various modifications will occur to those skilled in the art in. the structural features of the aperture frames as well as the disposition and configuration 0f the various members going to make up this invention as a whole as well as in its several parts and no limitation is intended by the foregoing description, specification, or illustrations in the accompanying drawings, except as indicated in the appended claim.
What is claimed is:
A prefabricated aperture frame of sheet metal assembled without the aid of special tools, including in combination, a lintel, including a top wall, side walls and a lower wall including a door stop formed with square ends and tabs projecting longitudinally from the ends, and further formed with slots in its lower wall adapted to receive tabs, two side members, each formed with mutually facing walls including door stops, a front side wall, a rear side wall and a back wall, the facing walls and door stop at the top terminating short of the top of the side walls, the ends of the lintel lying between the front and rear side walls of the members, said facing walls formed with tabs at their upper ends lying in the slots of the lower wall of the lintel, plates, one positioned between the front side Wall and the rearside wall of each of the members and attached to the back walls thereof, said plate formed with slots in which lie the tabs of the lintel, all of said tabs being bent over against adjacent surfaces whereby the lintel and the side members may be shipped disassembled and assembled at the place of use, and means for retaining the lower ends of the side members in spaced relation.
