6 Claims. 1

This invention relates generally to hinges, and more particularly to hinges suitable for the mounting of hollow metal doors on sheet metal cabinets or the like.

One of the purposes of my present invention is to provide a hinge which will serve, in addition to its hinging function, to reinforce and strengthen the sheet metal door which it supports. With this object in view, the door wing of the hinge is designed to be located within the hollow door where it is concealed from view and serves both as a door support and a door reinforcement.

Another object of my invention is to provide a hinge by which a door may be supported so that no portion of the hinge or the hinged edge of the door will project beyond the plane of the side of the cabinet during any of the opening or closing movements thereof. A cabinet may accordingly be placed in a corner of a room or with its side against a wall, or two cabinets may be abutted together, without interfering with the opening of the doors.

A further advantageous feature is that th hinge also serves as a stop to limit the openand attached to the door of a cabinet by permanent spot welding.

Other objects and advantages of my invention should be readily appreciated as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawings.

Referring to the drawings,

Referring more specifically to the structural details included in the preferred embodiment of the invention disclosed on the drawings, one end wall of a container or cabinet, such as a kitchen cabinet, locker or the like, is designated on the drawings by reference character iii. The wall, as will be obvious, is of sheet metal formation with its margin bent to form a channel-shaped stile l4 presenting a door frame wall I5 upon which the door I6 of sheet metal hollow construction is adapted to be mounted.

While two or more hinges are customarily employed for the mounting of each door, I have herein shown, for illustrative purposes merely, one of such hinges constructed in accordance with my invention. The hinge, generally speaking, is of three-piece construction, comprising a cabinet wing I l, a door wing 18, and a pintle I9 by which said wings are pivotally connected together.

The cabinet wing, which is formed of sheet metal, consists of a base portion 2| adapted to be mounted on the stile M by means of a plurality of screws or bolts 22, an outwardly extending arm 23 projecting at an incline from the portion 2|, as will be apparent from Fig. 5, and an extension 24 of said arm bent to project therefrom in a plane substantially perpendicular to the plane of the base portion 2|. The free margin of the extension 24 is rolled back to form a journal 25 for the pintle I9. The wall 15 of the cabinet is provided with an opening 3!] for each cabinet wing.

The door wing is also formed from a single sheet of metal, the fabrication of which into the completed wing will be readily apparent from a consideration of Figs. 8 to 12, inclusive. As shown in Fig. 8, a metal sheet is cut or stamped to form a blank shaped as shown having an elongated cen- Qtral notch 26 along one edge disposed between stantially parallel with the wall 3 i, thus providing a channel-shaped member consisting of the base or bottom wall 33, the marginal wall 3| carrying the journals 2'! and 28, and the main body wall extending parallel with the wall 3 l. The central portions of this body wall are now bent at right angles to the plane of the body on the lines34 and 35 (Fig. 11) to provide the flanges 36 and 31 projecting outwardly from the attaching portions 38 and 39 remaining in the plane of the original blank. It will be apparent, particularly from Figs. 1 and 4, that the flanges 36 and 3: are respectively notched, as indicated at ii and 42, to underlie and accommodate the journals 21 and 28, respectively, and that they extend outwardly substantially the depth of the door, that is, from the inner wall 43 to the outer wall fil -l thereof, so as to strengthen andreinforce the door and prevent inward bending or collapsing of the outer wall under stress. The reinforcing flangesare spaced apart sufficiently to accommodate between them the projecting 'arm of the cabinet wing.

Similarly, the journals. 27' and 28 on the 'door' The opening is formed by 1 cutting the door wall and bending inwardly the wall material around three sides of whic the cuts have been made to thereby'form the inwardly pro jecting flange it which, as will be apparent from Fig. 1, extends between the reinforcing flanges 36 and 3? and also extends to the outer wall M of the door to further strengthen and rigidify'ihe struc-.

ture. The transversely extending. flanges 36, 3! and surround the hingeopening 65 so as to preclude the insulation or silencing material 'customarily placed within the door'from working out through said hinge opening.

When the hinge has been positioned within the E door, as illustrated, with the arm 23 projecting through the opening the door wing is spot welded to the door, particularly along the base wall 33, thereby securely mounting the hinge and For the purpose of providing addition-.

It will be apparent that the axis about which the door will pivot in its opening and closing movements is spaced a substantial distance outwardly from the face of the cabinet. In fact, the pivot pin or pintle is located adjacent to the plane of the outer face of the door. The hinged edge of the door will during the opening and closing movements of the door swing in an arc which never intersects the plane of the side wall of the cabinet. The cabinet may, therefore, be located in a corner of a room close against the wall without interfering with the movements of the door, or two cabinets may be mounted in juxtaposition, as illustrated in Fig. 7, without the adjacent doors interfering with each other during their opening and closing movements.

From Fig. '7 wherein the door of the left-hand cabinet is shown as fully open, it will be manifest that the cabinet wing of the hinge presents a surface in the path of the reinforced wall at the inner side of the hinge opening, which serves as a stop or abutment to limit the extent of the opening movement of the door. The abutting surfaces forming the stop are concealed so that the chipping or marring of an exposed surface or" the door by contact with a stop is obviated.

From the foregoing .it will bemanifest that I have provided a cabinet hinge which can be economically. manufactured and easily installed, and which, inaddition to its hinge function as a pivotal door support, also serves to strengthen and reinforce the door structure. The hinge is mounted within the door, instead of on the outside, and is therefore not visible, and its pivot pin is. so located that a wall or another cabinet abutting the side wall of the cabinet on which the door is mounted in no wise interferes with the opening and closingof the door.

The structural details illustrated and described may be varied within considerable limits without exceeding the scope of the invention as defined in the following claims.
