UNITED STATES PATENT OFFICE DOOR HINGE Richard T. Keating, Ghicago, Ill.
Application June I0, 1950,'Y Serial No. 167,319
6 Claims.v (Cl. 16a-,135)
This invention relates to hinges and" hasV particular reference to a novel concealed hinge having means for holding a door closed or open at will; in the preferred embodiment of the invention, the several' component parts of the hinge are sor designed that it is particularly well suited to useA in connection With the doors oi sheet' metal cabinets.
'It is a primary object of 'the invention to providea hingev oi the concealed type which, while entirely out of View, is adapted to hold the door tlrmly closed, or to hold' itY fully open when once moved' to' the open position, and to limit its swinging movement to prevent itv from swinging beyond fully opened position.
A iurther objeetof theinvention` is to provide a: concealed hinge of more simplified' constructiongthan those'heretofore used, yet'k of greaterphysical strength and so designed that it is long lasting'and not subject to mechanical difliculties, particularly diioulties arising from minor misal'ignment of the parts, which cause so much trouble with conventional hinges.
It is a further object of the invention to pro vide a concealed door hinge having spring means to hold the door either open or closed, wherein thefeiective force exerted by the spring is easilyand conveniently adjusted as required.
A further object isto provide an improved and simplied concealed hinge wherein the several partsy employed are simple in construction and x'rnary bev economically manufactured' by ordinary factory methods, so that the hinge maybe pro duced in large quantities in a convenient 'and economical manner.
Further objects will appear in the disclosurel hereinafter, wherein the invention is described in a4 preferred-embodiment illustrated inthe present drawings, of which;
Figure 1 is a perspective view of' a deep fryer having a* sheet metal housing and a door thereonhinged in accordance with the present teachings: Figure 2 is a fragmental detail' sectional view takensubstantially onA theA plane ofthe. line 2-2 ot'Figure I and illustrating a hinge as contemplatedby this disclosure; Y
Figure 3 is a view similar to Figure 2, but showing the parts of the hinge in the positions they assume when the door is in fully open position; and
Figure 4 is a fragmental perspective view of the'inside of the door and a portion of the corner post -of the cabinet. showing the several parts inV fullyv open position.
Asl illustrated, the hinges III comprising; the subject matter of" the present invention are shown as applied to the door- II of a deep fryer having a tank I 2-', heatl transfer tube I3 and splash shield I4, all surrounded by and enclosed in a sheet metal cabinet I5 mounted on a base portion i6. As shown, the door has a center perforation I'l through which a regulating dial I8 of' the gas burner of the device may be` adjusted', but'this is of course a matter of choice and forms no part of the present invention'.
It is contemplated, however, that the door II shall be mounted on the hinges I tol provide unrestricted-access to the gas burner and tothe other interior parts of the unit, and it is in the construction of these hinges thatv the novelty of the present invention resides.
With reference now to Figures 2 and 3, it will be seen that the cabinet I includes a corner post 2I. which, as' shown, is in the form of a square metal tube, over which the sheet metal oi?l the cabinet I5 is folded' tor form a front-harige 22' surrounding the open doorway' 23 ofthe unit. The door II comprises a single integral metal plate or sheet having its top, bottom and side edges shaped inwardly in gradually curved portions` 24 terminating in a right angle bend 25 and inwardly extending ilanges 26. The flanges '26 (which extend around the top, bottom and both sides of the door) dene the inner plane of the doonwhich isy spacedv from the outer sheet II a distance sufficient-to give an appearance of adequate thickness to the door structure. Also, the` contoured surfaces 24 give considerable rigidity to the entire door member; The door may beprovided, however, with a vertical reinforcing member 21 havingA` its outer edge 28; secured to the'v inwardly extending flange 26` on the hinge side of the door and being'oiset at 29 so that its innerr flange 30 extends to and. may be welded on the inner surface of the outer metal sheet I I of the door structure. y
The hinge mechanism with which the present invention is concerned comprises a pair of brackets 3| secured to the inner surface of the re@ iniorcing member 21 and spaced apart from each other, but joined by a vertical hinge pin 32'. The hinge pin 32 extends through an aperture in a right angled oiset portion 33 of av hinge slide or mounting rod 34, which extends inwardly through apertures 35 and 36 in the corner post 2'I of the cabinet and is provided at its inner end with a coiled compression spring 31, an adjusts ing nut 38 threaded on the end of the rod 34 and a lock nut 39 to secure the adjustir" nut against accidental loosening. 'I'he rod` 34v is thus con'- nected to the offset portion 33 by a right angle bend 4|, and the reinforcing member 21 is cut away with an oversize aperture t2 to clear the rod and permit the hinge to swing between the closed position illustrated in Figure 2 and the fully opened position illustrated in Figures 3 and 4.
It will be seen from examination of these figures that as the door is opened, it will tend to pivot on the extreme edge 25 and will draw the hinge pin 32 outwardly to shift the slide 3A longitudinally in the apertures 35 and 36, compressing the coil spring 3l. Thus, the force exerted by the spring 3'! will normally tend to hold the door closed and will offer controlled resistance to opening m-ovement until the parts have moved to a position approaching the fully open position of Figure 3. As the parts assume this position, the edge portion 25 of the door will have moved to the right beyond the center of the hinge pin 32 and to a point where it comes into abutting relation with the slide rod 34. The slide rod 34 thus acts as a limiting stop for the hinge and limits the Iopening movement thereof, without the necessity of any additional auxiliary devices as are customarily employed in other hinged structures. Moreover, the door, when once opened to the right angle position illustrated in Figure 3, will maintain itself in open position, since the point of contact between the inner edge 25 of the door and the front flange 22 of the cabinet is now to the right of the center of the hinge pin 32, so that the inward force exerted on the hinge pin by the compression spring 31 tends to swing the door further open and is restrained by the contact between the inner edge of the door and the surfaces of the slides 34 on both the upper and lower hinges. It will be understood, of course, that while only one hinge of the door has been illustrated in detail, it is contemplated that both of the hinges I0 will be identical, and that they will be positioned above each other and with the hinge pins in substantial alignment.
It is to be noted, however, that the functioning of this form of hinge will not be materially affected by slight misalignments of the two or more hinge pins 32 which may be employed, since the axis of the cylindrical slide rods 34 is at right angles to the axis of the hinge pins, so that if anyv minor misalignments exist between these pins, the slide rods 34 may rotate slightly in the apertures 35 and 36 and give adequate compensation therefor without imposing undue strains on the door or making it diicult to open andv close. This is accomplished, moreover, without any detrimental effect on the eniciency of the hinges in holding the door in its closed position, since in the closed position illustrated in Figure 2, the center of the hinge pins 32 is spaced considerably inwardly from the extreme edge 25 of the door panel so that the combined effects of both of the springs 3'! of the hinges draw the door panel inwardly to hold it in firmly closed position.
