Hinge having varied height offset leafs

Abstract

A hinge structure includes two sections, each of which incorporates a flange structure attached to a cylindrical pin holding part. The pin is secured in one of the cylindrical parts and the other cylindrical part removably receives the pin. The flange structures for attaching the hinge to a door and to a door jamb include parts of L-shaped cross section extending tangentially from the cylindrical parts with the attaching flanges either forming part of the outboard section or forming part of an additional L-shaped part attached to the outboard edges of the first L-shaped parts. One embodiment includes an additional bend for attachment to a grooved or notched door jamb. Another embodiment includes an elongated rod with eyebolts affixed in grooves near its ends for attachment to a jamb and having flanges located adjacent the eyebolts for attachment to the door. This embodiment leaves the decorated rod exposed along the height of the door.

Description

SUMMARY OF THE INVENTION

This invention relates to a hinge assembly and more particularly to a hinge assembly having application for use in cabinets and the like where such hinges need to be both functional and aesthetically pleasing.

In one embodiment of my invention the hinge structure is formed of two sections with a separate cylindrical pin holding part in each section and with the attaching flanges tangentially attached to the cylindrical posts. The attaching flanges which attach to the door and to the door jamb are offset from the tangential position by means of parts of L-shaped cross section. Fastened to the outboard edges of these parts are the screw holding flanges. In one embodiment which is designed for attachment to a door having a longitudinal groove or offset, a double L-shaped flange structure is employed to provide a hinge which is almost entirely invisible when the door is closed except for the cylindrical pin holding parts. Another embodiment includes an elongated decorative rod having a finial at each end and which includes a pair of grooves holding an eyebolt for attachment to a door jamb. Inboard of the eyebolt and groove are a pair of flats to which are fastened offset mounting flanges for attachment to a cabinet door. In some embodiments the cylindrical parts and the pin are arranged so that the door may be easily removed if desired by simply lifting the door off of the pin of the corresponding cylindrical part attached to the door jamb.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a cabinet door 10 is shown mounted in a cabinet 12 and supported on a pair of hinges 14 which are so designed that only the cylindrical pivot structure is visible. Details of this hinge will become apparent from consideration of FIGS. 2, 3 and 4. The hinge structure 14 includes a jamb member 16 having a first hollow cylindrical part 18 which has one end closed and to which is attached a finial 20. A flange structure is tangentially attached to cylindrical part 18 which includes a first offset section 22 of L-shaped cross section which is approximately the same length as the height of cylindrical part 18, and an additional section 24 attached at a right angle to the outboard edge of section 22 and which is approximately twice the height of section 22. Secured in the interior of cylindrical part 18 is a cylindrical pin 19 which is fitted into cylindrical part 28 when the hinge is assembled. The door member 26 also includes a hollow cylindrical part 28 having one closed end to which is attached a finial 30. Tangentially attached to cylindrical part 28 is a support member 34 having an L-shaped cross section and having an L-shaped extension including an elongated flange 36 attached at right angles at its outboard end. The length of flange 36 is approximately twice the height of cylindrical part 28. FIG. 3 shows the door jamb member 16 attached to a jamb 38 and door member 26 fastened to a door 40 formed with an offset by means of screws 37.

A second embodiment is shown in FIGS. 5, 6 and 7 and is designed for use where the door is not offset as shown in FIG. 3 at numeral 42. In this application the hinge structure is almost as unobtrusive as is the first embodiment discussed above. This hinge includes a jamb member 44 having a cylindrical part 46 and a flange 48 attached tangentially to the cylindrical part having an L-shaped cross section, with the outboard part of the flange including an elongated portion 50 which is approximately twice as long as the height of the cylindrical part 46, and which is turned ninety degrees at its line of attachment to flange structure 48. A door member 52 includes a cylindrical part 54, a flange structure 56 having an L-shaped cross section and an elongated portion 58. A pin 60 is secured in the hollow interior of cylindrical part 46 and extends a significant distance such that when parts 44 and 52 are put together, pin 60 is inserted into cylindrical part 54. Finials 62 and 64 are fastened at the closed ends of cylindrical parts 54 and 46 respectively.

The manner of attaching the hinge described above is most clearly shown in FIG. 6 where the door 66 and its jamb 68 are shown in section and the hinge members 44 and 52 partly in section. The flange 48, 50 is fastened to jamb 68 by means of a plurality of screws 70, only one of which is shown. Flange 56, 58 is attached to an edge of door 66 by means of screws 72, one of which is shown. With the members 44 and 52 in the positions shown, the door is open somewhat more than ninety degrees. As the door is moved counter-clockwise, it carries member 56 until it closes against member 44 leaving the hinge parts as shown in FIG. 5.

An additional embodiment of my invention is shown in FIGS. 8 and 9. FIG. 8 is a partial plan view of a hinge structure which includes an elongated rod 76 which is turned to provide a decorative finial 78 and a groove 80 (see FIG. 9). An eye bolt 82 including a long threaded arm with a threaded nut 84 is attached to rod 76 with the eye part located in groove 80 having clearance to permit the eye bolt to rotate freely on the groove, but not permitting axial movement along the rod. Displaced a short distance toward the center of the rod is a flange structure 86 which is rigidly attached to the rod in any suitable manner to provide a mounting means for carrying a door. One such means is to provide a flat on the rod and to provide its flange structure with a mounting surface 88 against the flat which can be pinned or welded to the rod. An intermediate connecting section 90 connects this mounting surface 88 to the flat flange member 86 to which the door 92 is attached. The height of this connecting section may vary depending upon the thickness of the door 92. The eye bolt 82 is fed through a drilled passage in jamb 94. The structure at the upper end of rod 76 is essentially a mirror image of that described and the length of rod 76 between flange members 86 will vary with the height of the door 92. If door 92 were very long (such as over four feet long) a third intermediate flange member 86 and/or eyebolt might be affixed to the center of the rod. With this arrangement, the rather large decorative rod having a finial at each end is prominently displayed along the entire edge of the door.

FIG. 10 and 11 show a simplified version of my hinge useful for doors which incorporates the feature of forming the hinge into two easily separable parts. In this embodiment the cylindrical part 96 is formed of one piece with the flange 100 by cutting the part to size and rolling the cylindric part. It is then notched longitudinally a short distance and the parts rolled inwardly to close the end. A pin 98 is secured within the cylindrical part 96 for attachment to a door jamb. The mating section includes a cylindrical part 102 rolled in a similar manner having a flange 104. Each of the cylindrical parts 96 and 102 are formed as described and are closed at their outboard ends. FIG. 11 is a top view of the hinge of FIG. 10 and shows cylindrical part 102 and flanges 100 and 104. This design is simple but effective because, unlike the usual door hinges, the pin cannot be removed with the door locked.

From the foregoing it will be recognized that I have provided a plurality of hinge designs which are highly functional, convenient to install and use and which may be installed in such a way as to be very pleasing in appearance. Two embodiments are almost invisible with the door closed except for the cylindrical parts. With particular attachment means and decorative features have been shown and described, those skilled in the art will be aware of modification within the scope of the attached claims.
