HINGE STRUCTURE 7 This is a continuation-in-part of my application, Ser.
No. 454,013, filed Mar. 22, 1974.
BACKGROUND OF THE INVENTION 1. Field of the Invention I H 1 This invention relates to hinge structures as usedfor example with door and window frames and doors and windows hingedly mounted therein and wherein the frames and doors and windows are generally formed with aluminum extrusions. V
2. Description of the Prior Art Prior structures of this type have employed -doo r frames with hinge forming components and hinge leaves registrable therewith and springs positioning pintles in operative relation thereto, as for examplein US. Pat. No. 2,903,735. Still other arrangements of spring urged pintles in hinge constructions may be seen in US. Pat. Nos. 3,375,546, 367l,99 8' and 3,673,636.
This invention is a substantial improvement over the prior art structures as for example that set for th in US. Pat. No. 2,903,735 in that the hinge leaf, the pintles and the spring which will hold them in operativerelation between the hinge leaf and the matching configurations in the door or window frame are pre-asseinbled and arranged to be manually moved to temporary inoperative position when the door or window is actually installed in the frame at the point of use.
SUMMARY OF THE INVENTION A hinge structure comprises a hinge leaf having a pintle receiving knuckle thereon, a pair of pintles therein, a coil spring positioned between the pintles and a large cutaway area in the knuckle so that a portion of the coil spring can be temporarily moved out of the knuckle to re-position the pintles within the knuckle whereby the hinge leaf may be moved into a cutaway section of a pintle receiving configuration in a mounting frame so that release of the spring permits it to assume its normal position and move the pintles into hinged relation between the hinge leaf and the pintle receiving configuration of the frame.
DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a hinge leaf with parts broken away and parts in cross section and illustrating pintles disposed in the knuckle portion thereof and spring means engaging the pintles, broken lines illustrate a position to which the spring may be moved and temporarily held in inoperative relation;
FIG. 2 is an end elevation of the hinge leaf seen in FIG. 1, broken lines illustrate the spring moved from its normal position; and
FIG. 3 is a horizontal cross section through a construction including a door frame and a door and illustrating the hinge leaf of FIG. 1 in operative position in a cut-out section of the door frame.
DESCRIPTION OF THE PREFERRED EMBODIMENT In its simplest form the hinge structure disclosed herein consists of a hinge leaf 10 apertured at 11 so that it can be attached to a door or window frame or the like and having one longitudinal edge thereof formed in a continuous cross sectionally circular knuckle 12 with a portion of the knuckle 12 between the ends thereof .beingcutawayas at 13 to'form" an elongated, wide access opening therein. A pair of pintles 14 are slidably positioned in the opposite end portions of the knuckle IZ andare partiallyretained within the knuckle 12 by small dimples ,15 formed inthe walls of the knuckle 12 adjacent the endsthereof. Each'of the pintles 14 has a central portion, an outerend extension 16 of smaller diameter than the ,central portion and a tapered inner end portion 17. The tapered inner end portions 17 of thepintles are frictionally engaged in the ends of a coil spring 18. V I s The pintles. 14 are thus normally held in the position shown in solid lines in FIGS. 1 and 2 of the drawings by the coil spring 18 which is normally on an axial center line therebetween. g n,
In FIGS 1 and 2 of the drawings the coil spring18 is illustrated in its normal straightlin e position in the knuckle 12 of the'hinge leaf '10 and broken lines show it temporarily held in bowed position as it may be moved'by the thumb of awor'kman holding the spring 18 so as'to partially retract the; pintles 14 to enable the hinge leaf 10 and the pintles 14 to be positioned in a cutaway section of a knuckle configurationin 'a frame.
By referring'n'ow to FIG. 3 of the drawingspthe complete hinge structure of the invention may be'seen to include the hinge leaf 10 heretofore described and a mounting'fram'e'19 which includes a continuous'longitudinally extending, cross s'ectionally circular"pintle'receiving knuckle configuration 20. Two or more areas of the pintles receiving knuckle configuration 20 are cutaway, the length of the cutaway areas being slightly greater than the length of the knuckle 12 of the hinge leaf l0 heretofore described so that the knuckle 12 on the hinge leaf 10 may be positioned in the cutaway area of the frame 19. When the knuckle 12 of the hinge leaf 10 is so positioned, the outer end extensions 16 of the pintles 14 will move outwardly of the ends of the knuckle l2 and into the pintle receiving knuckle configuration 20 of the mounting frame 19 as urged by the coil spring 18 when the same is permitted to assume its normal position.
Bushings may be positioned between the pintle receiving knuckle configuration 20 and the ends of the knuckle 12 in the hinge leaf 10 if desired as will occur to those skilled in the art.
It will thus be seen that the hinge structure disclosed herein provides for the pre-assembly of the hinge leaf 10 to include the pintles 14 in the knuckle 12 thereof and the coil spring 18 therebetween with the small dimples 15 in the knuckle 12 holding the pintles 14 in the knuckle 12 to insure a complete and useable hinge leaf assembly which may be attached as by fasteners 21 to a door or a window 22 as seen in FIG. 3 of the drawmgs.
Those skilled in the art will observe that when a door and a door frame or a window or window frame are installed in a building, a frame such as the mounting frame 19 disclosed herein is cut to fit the opening and installed therein by fasteners all as known in the art. Each assemblied hinge leaf 10 to be used may then be positioned in the respective cutaway portion of the pintle receiving knuckle configuration 20 of the mounting frame 19 when the spring 18 is partially withdrawn from the knuckle 12 by the workman so as to permit the pintles 14 to move into the ends of the knuckle 12. Release of the spring 18 positions the end extensions 16 of the pintles 14 in the pintle receiving knuckle configuration 20 of the frame 19 to movably attach the hinge 3 leaf l thereto. The door or window may then be attached to the hinge leaf 10.
If desired, the procedure may be reversed with the hinge leaf attached to the door or window at the proper locations thereon and then positioned in registry with the cutaway section of the pintle receiving configuration of the mounting frame 19.
The above-described structure provides a relatively easy and fast assembly of doors and windows in mounting frames at their point of use and is versatile in that it can be used on windows and doors of various sizes and shapes.
Although but one embodiment of the present invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention.
Having thus described my invention, what I claim is:
l. A hinge structure for mounting a closure in an opening comprising a mounting frame secured in said opening, an elongated knuckle configuration on said mounting frame, a plurality of cutaway sections in said knuckle configuration, a hinge leaf for each of said cutaway sections, an elongated secondary knuckle on said hinge leaf of substantially the same cross sectional configuration as said first mentioned knuckle configuration, a cut-out section in said secondary knuckle inwardly of the ends thereof, a pair of pintles movable longitudinally within said secondary knuckle on either side of said cut-out section therein, a spring positioned in said secondary knuckle between said pintles normally urging said pintles outwardly of the ends of said secondary knuckle, at least a portion of said spring being manually movable through and outwardly of said cut-out section of said secondary knuckle and distorted areas in the opposite ends of said secondary knuckle engaging said pintles to hold the same partially within said secondary knuckle and wherein said cut-out section in said secondary knuckle is large enough to permit a major portion of said spring to be moved outwardly of the secondary knuckle therethrough.
2. The structure set forth in claim 1 and wherein said spring is a coil spring and the end convolutions thereof are frictionally engaged on the innermost opposite ends of said pintles so as to be attached thereto and be movable therewith.
3. The structure set forth in claim 1 and wherein said pintles have extensions on their innermost opposite ends with respect to said secondary knuckle in which they are positioned, said extensions being of relatively smaller diameter than the remainder of said pintles and wherein the ends of said spring are engaged on said extensions.
