I claim
1. For use in mounting a door on a cabinet stile, a hinge including a mounting plate having a central portion with a single hole therein for receiving a fastening extending into the edge of the stile, a clamping portion extending generally normal to said central portion for tightly engaging the inner surface of the stile over a substantial area of contact, and a bifurcated portion defining a pair of leg portions extending generally normal to said central portion for tightly engaging the outer surface of the stile; a pintle mounted upon the rearward ends of the legs of the bifurcated portion and a door-supporting plate pivotally mounted on said pintle, said door-supporting plate including a flat portion disposed in the plane of said bifurcated portion when the door is closed and having holes therein for receiving fastenings extending into the inner surface of the door, said door-supporting plate having an outwardly offset portion as an extension of said flat portion engageable with said pintle, the flat portion of said door-supporting plate immediately forward of said offset portion being adapted to contact the outer face of the stile in the area between the legs of the bifurcated portion of the mounting plate when the door is closed.
2. A hinge as defined in claim 1 wherein the location of said pintle and the location of said offset portion of the door-supporting plate is such as to dispose the edge of the mounted door in overlapping relation to the edge of the stile.

Description:
BACKGROUND OF THE INVENTION
Conventional hinges for mounting of doors on cabinets and having a plurality of fastenings entering the stile of the cabinet are generally unsuitable when the stile is formed of material subject to splitting by the entry of those fastenings. If the number of such fastenings is reduced to a minimum, however, the hinge-mounting plate, or leaf, must engage the stile in such manner that the hinge and attached door, as a whole, will not shift with respect to the stile. This then, requires stile-engaging shoulders on the mounting plate and, when the door is to close substantially flush with the outer surface of the cabinet stile, such a plate shoulder may interfere with the other hinge plate, or leaf, attached to the door.
It is a purpose of this invention to provide an improved hinge by means of which disadvantage of this nature may be overcome when mounting a cabinet door on a stile formed of folded material.
SUMMARY
The present hinge comprises a mounting plate using a single mounting screw for attaching the hinge to the stile of the cabinet, and a door-supporting plate which may use any number of screws entering the inner surface of the door. A pintle joins the two plates and is positioned to allow an interleafing of portions of the two plates so as to dispose the plane of the door in its closed position closely adjacent the plane of the outer surface of the stile.
Among the objects of the invention are the provision of an improved hinge suitable for use with cabinets having stiles formed of folded material; a hinge which can be accurately assembled in place, upon both the door and the stile; and a hinge which requires no pretreatment of the door in mounting the door on the cabinet stile.
These and other objects and advantages of the invention will become more apparent as the description proceeds and when considered in conjunction with the accompanying drawings in which:
FIG. 1 is an elevation view showing a portion of a door mounted on a stile of a cabinet and employing the hinge of the invention.
FIG. 2 is a sectional view taken on line 2-2 of FIG. 1, and
FIG. 3 is an elevation view showing the interior of the door of FIG. 1, when opened to a position normal to its position in FIG. 1.
Referring first to FIG. 2, a typical use of the hinge involves the mounting of a door 10 upon the stile of a cabinet which is formed of grooved and folded laminated panels as more fully disclosed in my copending applications Ser. No. 662,936 and 678,935. Such a cabinet includes a sidewall comprising a thin outer lamination 11 of vinyl or other plastic bonded to a thicker lamination 12 of fiberwood, composition board or the like and which upon being suitably grooved, folded, and adhesively secured forms the stile portion of the cabinet.
The hinge is intended to permit the door to be mounted in substantially flush overlapping relation to the stile and with the plane of the inner surface of the door separated from the plane of the outer surface of the stile by only the thickness of the legs of the mounting plate now to be described. Moreover, the hinge assembly and its method of mounting serves to avoid splitting or separation of the folded stile material.
Accordingly, there is provided a hinge-mounting plate having a central portion 13 which closely embraces the edge of the stile and has an integral clamping portion 14 extending normally thereto and tightly engaging the adjacent inner surface of the stile. An integral clamping portion which is bifurcated with an upper leg 15 and a lower leg 16 extending normally to and rearwardly from the central portion engages the outer surface of the stile. The space 25 between these legs is occupied by the rearwardly extending central portion of the door-supporting plate with the corresponding parts interleaved when the door is closed. The clamping portions of the hinge-mounting plate contact the folded stile material over a substantial area and compresses the material to a certain extent when the fastening screw 17 enters the stile. With this arrangement it has been found that the single screw 17 passed through a corresponding hole in the described plate suffices to provide the necessary mounting and at the same time will not cause splitting of the folded stile material. This use of a single screw and the avoidance of screws passed into the stile from the clamping portions, as exemplified by the Collins U.S. Pat. No. 936,090 and the Bommer U.S. Pat. No. 1,904,120, for example, forms an important feature of the invention.
Projecting outwardly from and attached to the rearward ends of legs 15 and 16 are pintle housings 18, 19 with a pin 20 extending therebetween. As seen in FIG. 3, the curved distal end 21 of the rearwardly extending central portion 22 of the door-supporting plate embraces the pin 20. This central portion, moreover, has an offset section 23 which, when the door is closed, will fit between the housings 18, 19 of the pintle and will dispose the section 24 of that central portion in the space 25 between legs 15 and 16, as indicated in FIG. 3.
An enlarged flat portion 26 of the door-supporting plate is located at the forward end of the hinge assembly and is provided with a plurality of holes through which short fastening screws 27, 28 and 29 are passed into the inner surface of door 10. As will be noted, the rear edge 30 of that door is disposed forwardly of the offset section 23, but as seen in FIGS. 1 and 2 will be well outboard of the edge of the cabinet stile and will hide the legs 15, 16 and the major area of the central portion 24 when the door is closed. An attractive door mounting is thus presented. The door, which may be of any suitable material, does not require any work thereon preparatory to being mounted on the stile in the manner above-described.
Having thus described a preferred form of hinge, it will be understood that the invention may be embodied in other forms than that described as being the preferred form.
