- The present invention relates to a refrigertile member 6 and entering the wooden frame ator construction and more particularly to A the construction of refrigerator doors wherelin an enameled sheet is used for covering 6 said doors.
An object of the present invention is to improve the construction of refrigerator doors. i
In order to attain this object there is pro- 0 vided, in accordance with one feature of the invention, a refrigerator door having an inner frame with an enameled sheet metal outer sheathing member, said sheathing member having openings therein to register with the screw openings in hardware fittingsk to be mounted thereon, and hardware fittings having bosses extending downwardly from the under surfaces thereof and adapted to enter the openings in the sheathing member and rest upon the door framework positioned beneath the metal sheathing member. These bosses are aperturedvto receive screws by means of which the hardware fittings are secured to the inner framework, the mainl bot-- tom surfaces of the hardware fittings engag- -ing the enameled sheet to hold it in position. Y These and other features of the invention will be more fully brought out in the following description and the accompanying drawings, wherein:
Figure l is a view intransverse section through the edge of a refrigerator door and door opening vshowing a hinge embodying the present invention mounted to secure the door in position; and p Figure 2 is a view in top elevation of the hinge.
Referring to the drawings in detail, a rectangular wooden door frame A is constructed in awell known manner, having an outer frame portion 1 andan inner frame portion 2 permanently secured to each other so as to form' a unitary frame structure. The outer edge of this frame is beveled, as at 3, and is provided with a llaterally extending flange 4 at the outer edge thereof. The frame is grooved as at 5 to receive an angularly bent sheet metal facing member 6 which is secured in position by staples 7 penetrating lwardly projecting members An enameled outer sheathing member 8 is bent downwardly and inwardly around its outer4 edge to provide an extension to the 55 flange 4 of the frame. This enameled sheathing member is provided with openings 9 therein, the openlngs being sufficiently larger than downwardly extending projections 1() on a hinge 11 so as to permit these 60 projecting portions to freely enter these openings 9. A plate 12 is secured over the sloping outer face 3 of the frame A and this plate may be of phenolic condensation material, or other impervious substance.
An inner enameled sheet metal sheathing member 14 may be mounted over the inner side of the door frame, the sheathing member as illustrated, having a perpendicularly positioned flange l5 around the outer edge 70 thereof, which is adapted to fit into a recess 16 in the frame and may be held in position by screws 17 which pass through the plate 12, the flange 15, and into the frame A to hold the parts securely together. The con-.76 struction of the door opening in the refrigerator comprises a wooden lintel -18 having a wedge-shaped strip 19 secured thereto to give the proper slope to the door opening. A second plate 20, similar to the plate 12, iss@ secured in position thereon as by means of screws 21. This platexengages an inner lining member 22 which'may be of enameled sheet metal to form a tight joint between this lining member 22 and the plate 20.
An outer enameled sheathing plate 23 is secured to the outer surface of the refrigerator and has a perpendicularly positioned flange 24 adapted to fit in a rabbeted depression in the lintel 18 and engaged by the outer edge a@ of the plate 20. f i
The hinge 11 is of a conventional type of construction, with the exception of the down- 10 which extend a suiicient distance below the lower surface ne of the hinge to pass `through the openings 9 in the enameled sheathing'plates 8 and 23 and to rest upon the frame A or the lintel 18. l Screws '28 are inserted in openings in the 'bottom of depressed portions 10,'.tlniev openings being of a size to freely receive the screws therein and the screws are screwed into the framework A or the lintel 18 to firmly hold the hinge in position. In this manner the screws may be drawn up as tightly as desired with no danger of cracking the enameled coating on the sheathing plates 8 and 23 since the lower surface of the hinge is held in vertically spaced position from the adjacent surface of the framework. The length of these downwardly projecting members'l() beneath the lower surface of the hinge member is determined by the normal distance from the outer surface of the framework to the outer surface of the enameled sheathing plate and is such that the lower surface of the hinge or other fitting will exert a sufcient downward pressure upon the sheathing plate to hold it securely in position without exerting any downward bending moment upon the enameled sheathing members.
While the illustration shows the invention incorporated in a hinge it is to be understood that the invention is not limited to use with a hinge but may be used with any other fitting which it is desired to secure on the outer surface of the refrigerator by means of screws engaging the inner frame structure of the refrigerator.
A metal plate 26 is shown secured to the outer face of the framework so that machine screws 27 may be used to attach the fittings at a point near the outer edge of the frame,
but this feature of the construction is not intended to be included in the present invention, but is the subject of a separate application for Letters Patent, Serial No. 450,433, filed May 7 1930.
In use the present invention eliminates eX- cessive downward strain on the enameled outer sheathing member adjacent the screw openings which is present in ordinary types of fitting construction and greatly lessens the possibility of fracture to t e enameled coating on the sheathing members.
1. In a refrigerator, an inner frame, a sheathing member having apertures therein adapted to receive projections 011 'a tting member, a fitting member adapted to seat on said sheathing member, and having apertured projections extending downwardly below the lower surface thereof and adapted to enter the openings in said sheathing member and to rest upon said inner framework.
2. In a refrigerator'construction having a wooden framework and a sheathing member having apertures therein adapted to receive projections on a. fitting member, a fitting member having a main body portion adapted to rest upon said sheathing member and having projections extending downwardly from the lower surface thereof to enter said openings and to rest upon said inner framework, said projections being apertured to freely receive screws adapted to threadedly engage said framework.
3. In a refrigerator construction having a sub-framework and a sheathing over said framework, said sheathing having apertures therein adapted to receiveprojections on a fitting member, a fitting member having a main body portion adapted to overlie said sheathing member and having projections extending downwardly from the lower surface thereof to enter said openings and to rest upon said sub-framework. said projections being apertured to receive screws adapted to threadedly engage said framework.
4. In a refrigerator construction having a sub-framework and a sheathing over said framework, said sheathing having apertures therein adapted to receive projections on a fit-ting member, a fitting member having a main body portion adapted to overlie said sheathing member and having projections extending downwardly' from the lower surface thereof to enter said openings and to rest upon said sub-framework, said projections being apertured to receive screws adapted to threadedly engage said sub-framework, said projections extending below the lower surface of said fitting member a distance equal to the required distance between the surface of said sub-framework and the outer surface of said sheathing member.
