15 Claims. (Cl. 20-46) This invention relates to a self-closing door and interior door hinge assembly.

The invention contemplates the provision of special bracket means between the face plies of a builtup door and desirably fixed to one or both such plies independently of the filler. Further contemplated is a special gravity type hinge mounted, desirably by a single screw, upon one portion of such bracket means and in interlocking engagement with another to be confined in the interior of the door between the face plies thereof and to provide an exceptionally rigid and exceptionally neat means of supporting the door for free hinged movement in either direction from the central position to which it returns by gravity when displaced therefrom.

Cooperating with the portion of the hinge which brings about gravity return of the door, there is provided a remote hinge element likewise positioned between the planes of the exterior faces of the door and providing a pintle aligned with that of the gravity hinge.

In the drawings:

Fig. 1 is a view in side elevation of the door and hinge assembly embodying the invention.

Fig. 2 is a view illustrating in separated positions the component parts of a builtup door such as that used in the assembly of Fig. 1.

Fig. 3 is an enlarged detail view in vertical axial section through the gravity hinge device and associated parts of the door.

Fig. 4 is an enlarged detail view in vertical axial section through the upper hinge of the door shown in Fig. 1.

Fig. 5 is a view fragmentarily illustrating in side elevation and partly broken away to vertical section the several component parts of the gravity hinge used in the lower corner of the door. I

Fig. 6 is a view taken in horizontal section through the gravity hinge in the plane indicated at 6-6 in Fig. 3.

The door 7 is of a type best illustrated in the exploded drawing of Fig. 2. It comprises

pan-shaped face panels

8 and 9 having mating complementary marginal flanges 10 and 11, respectively. These pan-shaped panels are laminated together upon intervening multiple plies 12 of sound deadening material such as fiberboard to make a socalled flush type door, the margins of which are finished by the application of finishing strips 13 as best shown in Fig. 6.

In the past, where hinges have been applied externally to such doors, they have generally been connected to the weakest portions of such doors, at the edges thereof. According to the present invention, the filler plies 12 are deeply notched at 14 and 15 at the upper and lower inner corners of the door and the

panels

8 and 9 are connected within the aforesaid notches of the filler by hinge mounting and panel reenforcing brackets, each of which is desirably made in one piece as clearly appears in Figs. 2, 3 and 4.

The lower corner bracket 16 comprises a strap having a horizontal portion 17 and a vertical portion 18 connected by an integral angle at 19. Each of the aforeaten t said horizontal and vertical portions has relatively broad flanges fastened to the face ply 9 of the door. These flanges appear at 20 and 21, respectively, in Figs. 2 and 3.

Similarly, the upper bracket 23 as shown in Figs. 2 and 4 comprises integrally a pair of vertically spaced

horizontal portions

24 and 25 connected by an integral vertical portion 26. The several portions aforesaid are respectively provided with broad flanges at 27, 28 and 29, all of which are fastened to the face ply 9 of the door. Thus, in the fabrication of the door proper, the hinge mounting brackets are all initially fastened to face ply 9 to be handled unitarily therewith as the respective panels 3 and 9 are assembled to each other about the filler 14. In the final assembly operation, the

shorter flanges

30 and 31 of

bracket portions

17 and 18 are fastened to the face ply panel 8, this being possible after the door is otherwise assembled, by reaching into the notches at the corners of the door. Similarly, the

shorter flanges

32, 33 and 34 of

bracket portions

24, 26 and 25 at the top corner of the door are fastened to the inner panel 8 of the door at such corner.

At the lower inner corner of the door, the

panels

8 and 9 have shallow notches at 35 and 36, respectively. The hinge supporting arm 37 of the jamb mounting plate 38 projects into the resulting notch in the door corner. The tapered bushing 39 carried by such arm receives the complementarily tapered lower end of the cam stud 40, which is fixed therein by nut 41. The cam 42 encircles the upper end portion 43 of the stud and is seated upon a shoulder at 44. Within portion 43 is a bearing 45 for the pintle 46. Extending transversely through the pintle, and fixed to project laterally therefrom, is a shoulder rivet 47 which provides a ball race for hearing 48 of the cam roller 49. A bracket 50 supports the outer end of shoulder rivet 47 and is secured by a screw 51 to the upper end of pintle 46. When the bracket 50 is connected with a door and the cam sleeve 42 is properly oriented with respect to the jamb, the roller 49 will ride on the curved cam margin 52 at the upper end of sleeve 42 to return the door to its normally centered position whenever the door is displaced therefrom.

The bracket generically designated by reference character 16, and permanently fixed within the door between the

face panels

8 and 9 thereof, as above described, carries an attached nut 54 attached to its portion 18 as best shown in Figs. 3, 5 and 6. The horizontal arm 17 of this bracket has an aperture at 55 into which the head of screw 51 is received as a dowel, no fastening being necessary at this point. To assemble the hinge organization in the door, it is only necessary to thrust the head of screw 51 into the opening at 55 in the bracket and to thread the single retaining screw 56 through the bracket 59 and into the fixed nut 54. t

A. closure 57 apertured to receive screw 56 is also held by this screw in a position to close the lower side of the chamber thus formed within the door to receive the hinge. The closure 57 has horizontal and vertical portions as best shown in Fig. 3 and Fig. 5 and has external flanges 58 to embrace the outer faces of

panels

8 and 9, as best shown in Fig. 1 and indicated in dotted lines in Fig. 3.

Ordinarily the hinge will be entirely assembled in the door when supplied by the manufacturer with the exception that the stud 40 will not necessarily be assembled to the bushing 39 in arm 37 of the jamb mounting clamp 38. After the jamb mounting clamp is fixed to the jamb, the stud 40 will be dropped into the tapered bushing 39 and drawn tight with nut 41 to complete the hinge at the lower corner of the door.

At the upper corner of the door, the jamb clamp 60 carries an arm 61 which has a bearing 62 both rotatably and slidably engaged with the upper pintle 65. Since the notch in the 'door at the upper corner does not open to the top thereof, the trimming closure 66 is C-shaped as best shown in Fig. 1. It has upper and lower apertures through which the pintle 65 extends into engagement with the upper and lower horizontal portions 24 'andf25 of the door reenforcing bracket. At its lower .end, pintle 65 is :threaded at 68 and it is engaged in a f'thr'ea'ded aperture of a nut element 69 welded to the bra'ck'et \portion 25, as best shown in Fig. 4. It may be introduced through an opening provided at '70 in the :top of the door and it is provided with a screwdriver slot :at 71 to enable it to be turned down into nut 69 .asshown and described.

Within the notch of the door, the pintle 65 passes througha fiat-faced barrel 75, the surfaces of which are ordinarily-flush with

door panels

8 and 9. The barrel 75 has a slot-at 76 through which the jamb-supported arm 61 enters to provide a'bearing for pintle 65. As the door turns and moves vertically in response to the cam action of the roller 49 riding on the cam surface 1 52 of the cam sleeve 42, the barrel 75 partakes of its vertical movement but is held by arm 61 against oscillation withthe door. The length of slot 76 accommodates the relative movement of arm 61 as the door rises and falls.

-It will be evident from the foregoing that our hinge and door assembly .provides an unusually neat organization in which both the upper and lower hinge elements operate within and between the faces of the door, the pintles, in each case, being housed between portions of the face panels of the flush door. Yet the construction is an'unusually sturdy one, the hinge being mounted on :brackets which are fastened across the interior of the door to both of the face panels thereof. A very substantial advantage is the ease with which the hinge assemblies may be mounted to the door. A single screw suffices in each instance, the screw comprising the pintle itself in the case of the upper hinge assembly.

In the assembly of the door and the connection of the hinge brackets to the door parts, any approved means of connection may beused, screwing, bolting and welding being conventional for the purpose. Such details form no part of the present invention and we do not wish to limit ourselves to particulars given merely by way of exemplification but have defined our invention in the appended claims.
