Jorgensen, 116 2nd Ave. S., Edmonds, Wash. 98020 Filed May 2, 1967, Ser. No. 635,576 Int. Cl. Ed /00, 11/04 US. Cl. 16-128 7 Claims ABSTRACT OF THE DISCLOSURE This invention relates to hinges, particularly to cabinet door hinges.

The hinge of the present invention is designed to replace pin-and-knuckle type hinges over which it has the following advantages:

(1) Eliminates the pin.

(2) Requires but one screw for mounting.

(3) Is silent and non-squeaking in operation.

(4) Includes as a component a conventional low cost door leaf member.

(5) Includes a low cost plastic base member which makes possible interesting decorative arrangements.

(6) Is easily and positively assembled.

(7) Is adaptable to various types of doors such as olfset, full-overlay, and flush-surface mount doors.

(8) Eliminates necessity of precision alignment and bore diameters of the leaf knuckles.

(9) Is installed rapidly and easily.

Broadly considered, the hinge of my invention comprises a leaf part and a base part. The leaf part comprises a conventional door leaf member having spaced apart barrel or knuckle extensions. The base part comprises a body, preferably made of plastic, dimensioned for insertion in the space between the barrels. It is secured to a structural member by suitable means, as by a single screw.

Bearing-forming means, for example, recesses dimensioned to receive the hinge barrels, are positioned one on each side of the base and arranged for bearing connection between the base and the adjacent hinge barrels. In this manner the hinge barrels replace the conventional hinge pin in forming bearings which support the door and permit its angular movement.

Considering the foregoing in greater detail and with particular reference to the drawing, wherein:

FIG. 1 is an exploded view of the presently described hinge in one of its embodiments;

FIGS. 2, 3 and 4 are views in plan, elevation and longitudinal section, respectively, of the hinge of FIG. 1, FIG. 4 being taken along line 4-4 of FIG. 2;

FIG. 5 is an exploded view of the hinge of the invention in a second embodiment;

FIGS. 6, 7 and 8 are views in end elevation, transverse section, and longitudinal section, respectively, of the hinge of FIG. 5, FIGS. 7 and 8 being taken along lines 77 of FIG. 8 and 8-8 of FIG. 6;

FIG. 9 is a perspective view of the hinge of the invention in a third embodiment; and

FIG. 10 is a perspective view of a base part employed in the hinge of FIG. 9.

The hinge of FIGS. 1-4 essentially comprises a leaf part, indicated generally at 20, and a base part, indicated generally at 22. The leaf part is intended normally to overlie the door and the base part normally to be afiixed to the door jamb, the cabinet side wall, or other structural member. However these usual positions of the parts may be reversed, if desired, in particular installations.

Leaf part 20 may comprise a metal hinge leaf such as is employed in a conventional pin and knuckle hinge. It comprises a leaf section 24 adapted to be secured by means of screws inserted through screw holes 26 to the cabinet door 27, which it overlies.

Leaf section 24 is formed in various shapes and configurations as required for adaptation to various types of door mounting, for example, surface mountings, full overlays, and offset mountings.

It is provided in the usual manner with knuckle or barrel extensions 28. These have aligned openings which normally receive the hinge pin. The barrels are spaced apart a predetermined distance and are formed with inwardly directed extensions 30.

Base part 22 replaces the conventional pin and plate fiounting components of the conventional pin and knuckle mge.

The base part comprises a body 32 which is made of a suitable material, preferably a deformable plastic such as nylon or polyethylene. It also may be fabricated from zinc, diecast metals or pressed, powdered metals.

Body 32 is dimensioned for insertion in the space between hinge knuckles or barrels 28. It is provided with means for attachment to a framing member 34. To this end it is formed with a tapered central opening 36 dimensioned to receive a signal wood screw 38 by means of which the hinge is attached to the structural member.

Bearing forming means are positioned one on each side of base part 22 for forming bearing connections between the base and the adjacent projecting ends 30 of hinge barrels 28.

In the FIGS. l-4 form of the invention, the bearingfor-ming means comprise bearing recesses 40 arranged diametrically opposite each other and dimensioned to receive the inwardly projecting ends 30 of binge barrels 28. These elements are retained to their assembled position by means of locking burrs 42.

To mount and assemble the hinge, leaf part 20 is secured to the door member. Base part 22 is snapped over barrel extensions 30 in the manner illustrated in FIG. 1. This is made possible by deformation of the plastic body of the base, which adjusts sufiiciently to permit the barrel extensions to pass locking burr 42 and seat in recesses 40. There thus is formed a journal bearing in which the hinge barrels themselves provide the mounting shafts. The door then is hung on the structural member by inserting screw 38 which not only supports the door, but also holds together the two hinge parts in working relation.

The embodiment of the invention illustrated in FIGS. 5-8 inclusive is similar except that the base part is divided longitudinally into two sections adapted to be placed on opposite sides of the hinge barrels. One of the sections is provided with barrel supports which underlie the barrels and absorb the thrust created during operation of the door.

To this end there is provided a leaf part indicated generally at 50 and a base part, indicated generally at 52.

As before, leaf part 50 may be of conventional design and provided in a plurality of configurations to conform to various door designs. It includes a leaf 56 provided with screw hole openings 58 dimensioned to receive the mounting screws by means of which the leaf is attached to the underlying door 59.

Leaf part 50 also is provided with integral barrels or knuckles 60. These have inwardly directed extensions 62 j and are provided with aligned, central bores which normally receive a hinge pin.

Base part 52 is divided longitudinally into two sections, one of which is indicated generally at 64 and the other at 66. Both of the sections of the base part are made of deformable plastic. Section 64 has a cross sectional area which is substantially greater than that of section 66 and is recessed to receive section 66 in nesting relation, as is particularly apparent in FIG. 7.

Base part section 64 includes a body 68, FIG. 8, dimensioned to be received in the space between hinge barrels 60. It also is provided with a central screw hole 70, and a pair of recesses 72 positioned on opposite sides of the body and extending in diametrically opposed directions. These correspond to recesses 40 of the embodiment of FIG. 1-4. They are dimensioned to receive the projecting ends 62 of hinge barrels 60 in bearing forming relation.

Base part section 66 includes a body 74 formed with terminal sections 76, the upper surfaces 78 of which are arcuate in configuration to conform to the contour of hinge barrels 60. The central portion of the body is provided with a screw hole 80.

Base part sections

64, 66 are designed for placement on opposite sides of hinge barrels 60. When they are brought together, the body 68 of section 64 enters the space between barrels 60 and abuts against the surface of body 74 of component 66.

In this position, screw holes 78, 80 align with each other so that they can receive a wood screw 82 by means of which the assembly may be secured to a door jamb, a cabinet side wall or other structural member 84. Also, component 66 nests within component 64, recesses 72 in the latter forming with arcuate surfaces 78 of the former a bearing housing which receives hinge barrel extensions 62 in bearing-forming relation.

The two

components

64, 66 are interlocked by suitable means, for example, by a snap lock including recesses 86 in component 64, and flanges 88 in component 66. When the three parts are assembled in the manner illustrated in FIG. 5, the plastic deforms sufliciently to permit flanges 88 to snap into recesses 86, thus holding the parts together. In use they are further secured by means of screw 82 which penetrates both components as well as structural member 84.

In the form of the invention illustrated in FIGS. 9 and 10, the arrangement of the bearing parts is reversed, i.e. the hinge leaf barrels or knuckles form the bearing component and the base part supplies the shaft.

Thus the hinge again comprises a leaf part, indicated generally at 90, and a base part, indicated generally at 92.

The leaf part 90 again is of conventional construction, being comprised of a leaf 94 with screw holes 96 for reception of the attaching screws. The leaf is provided with integral barrel extensions 98, which normally receive the hinge pin, the barrel extensions are aligned with each other and separated by a space which receives the base part of the hinge.

The base part 92 again preferably is made of plastic and is provided with a central screw hole 100 dimensioned to receive a wood screw 102 by means of which the hinge is fastened to the structural support.

The base part is provided further with a pair of oppositely-extending, short shafts 104. These extend diametrically opposite from each other and are dimensioned for reception in the aligned bores of hinge barrels 98. This may be accomplished during manufacture simply by wrapping the leaf extensions about the shafts. The desired journal bearing relation thus is created.

To mount the hinge of FIGS. 9 and 10, it merely is necessary to attach the leaf part to the door and the base part to the supporting structural member by running screw 102 through opening 100 and driving it into the underlying support.

It is to be understood that the form of my invention herein shown and described is to be taken as an illustrative example of the same and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.
