4 Claims. (Cl. 16-172) The present invention relates generally to a hinge construction and more particularly to a novel hinge assembly primarily adapted for pivotally mounting a metal door or closure on a sheet metal cabinet and the like.

An important object of the present invention is the provision of a novel snap-on hinge adapted to be mounted in a metal cabinet in such manner that the body of the cabinet and the door or closure therefor may be completely nished as separate units, after which the hinge wing on the door or closure may be snapped into position to complete assembly of the door or closure in the body of the cabinet.

The present invention further comprehends a novel snap-on hinge which greatly facilitates assembly or disassembly of the door or closure and whereby the hinged connection may be disengaged by simply inserting. the end of a screw driver or other instrument into the cabinet hinge wing and spreading the adjacent end of the spring clip to permit removal of the door hinge wing and its pintle or hinge pin together with the door or closure.

Another object of the present invention is to provide a novel hinge assembly concealed when the door is closed, and comprising a hinge wing axed to the cabinet, a hinge wing aixed to the door or. closure, and, a novel spring clip for connecting the wings in assembled relation but permittingV ready removal of the door or closure when required or desired.

By reason of the present novel hinge construction whereby Ilthe door or closure may beA easily and. readily removed from its hinged position in the body of the cabinet, any relinishing of the assembled door or closure which may be required and which frequently occurs in the metal industry may be most etectively accomplished.

Another and important object of the present invention is the provision of a novel snap-on hinge in the form of a spring clip adapted to pivotally connect a door Wing carried by the door or closure and a cabinet wing carried by the body of the cabinet, and permitting disconnection of these wings should the door or closure require removal for any reason.

Further objects are to provide a construction of maximum simplicity, efliciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

Referring more particularly to the disclosure in the drawing and -to the novel embodiment of a snap-oil hinge therein selected to illustrate the present invention, there is disclosed a novel snap-on metal hinge assembljI for hingedly or pivotally mounting a metal door or closure 10 upon a metal cabinet body 11 comprising a door wing 12 aihxed to the door or closure and pro'- Vided with a headed pin 13, a cabinet wing 14 and a spring clip 15.

The door wing 12 is provided at one end with a flange 16 which is preferably spot welded at 17 or otherwise rigidly allixed to an inturned ilange or, lip 18 on the door or closure 10. This flange 16 is shown in Figs. 2 and 3 as projecting through a slot in the edge 19 of the door or closure 10, and so contoured as to provide a complementary abutting surface with the inturned flange or lip 18, and when spot welded or aixed thereto proi vides a rigid assembly. The door wing 12 is provided at its other end with spaced legs or bifurcations 21 and 22 each bent or rolled back at 23 to conformably receive and anchor in its opening an end of the headed pivot pin or pintle 13', and is curved or contoured inter` mediate its flanged end 16 and these spaced bifurcations or legs 21, 22.

The cabinet wing 14 is provided with a base 24 having an elevated central portion 25, and spaced inwardly projecting flanges 26 extending at substantially a right.- angle to the base 24,. the wing 14 having an intermediate cut-out or notch 27 aligned with a cut-out or notch 28 in an inturned flange 29 of the cabinet body 11, per mitting rotation of the door wing 12- into the aligned cut-outs when the door or closure 10 is partially or fully opened (Fig. 3). By this construction and arrange'- ment, the door or closure may be opened through an arc A of substantially The cabinet Wing 14 is secured to the body 11 of the cabinet' in thel manner shown in Figs.. 2 and 3, in which the base 24 andV the spaced; anges 26 seat within and conform to the interior walls at the corner 31 of the cabinet body 11 with the flanges 26 preferably spot welded or otherwise allxed to the inturned ange 29 of the cabinet body.

The spring clip 15 is preferably formed of sheet spring metal and so contoured that the separate door wing 12 and cabinet wing 14 may be quickly and positively joined by a snapon hinge connection. To anchor this spring clip onto the cabinet wing 12, the clip is provided with spaced resilient arms or projections 32 and 33 so spaced apart and of such length as to tensionally receive therebetween the edge 35 and the elevated or raised central portion 25 of the cabinet wing 14, and with the free end 34 of the arm or projection 33 being bent inwardly to engage over the opposite edge of the raised portion 25 and anchor the yspring clip 15 to the cabinet wing 14. The other end of the spring clip provides a recess at 36 to conformably receive in the recess between this end and the arm or projection 32 the intermediate, exposed portion of the pivot pin or pintle 13, with the free end of the clip provided with an outwardly bent lip 37.

By reason of this novel snap-on hinge construction and its novel manner of assembly, the body 11 of the metal cabinet can be completely processed through the finishing department separately from the door or closure 10, and at a subsequent assembly line the door or closure can be inserted and its hinge wing lzsnapped into posiu tion to complete the assembly. With the spring clip 15 forming the hinge or connecting element being mounted upon the elevated 'or raised 'centralportion' 25 ofthe .base 24 of the cabinet Wing 14, and' with the ang'e'l ofthe door wing 12 spt'welded or rigidlyaxed to 'the flange 18 on the door or closure, inthe assembly of the door or closure 10 each pivot pin or pintle 13 may be readily aligned with its spring clip 15 and with the intermediate, expbsed portion of each pin or pintle 13 atv38 being' .guided into the recess 36 by the outwardly bent lip :37 of the spring clip when a lateral force is applied to .the pin or pintle 13.

To dis'engage the hinge elements, all that is required is the insertion of a screw driver or the like 38' (shown lin dotted outline in Fig. 3) into the cabinet wing'14 and manipulating the screw driver to spread the outwardly bent lip 37 of the spring clip 15 sufficiently to permit the `pin y'or pintle 13 to be lifted out of or disengaged from the recess 36 in the clip, whereupon the door or closure of the cabinet may be disengaged for reiinishing, repair or replacement. The hinge wings 12 and 14 may be formed of any relatively thin or sheet metal suitable for the purpose. Y
