HINGE Filed Jan. 23, 1963 2 Sheets-Sheet 2 United States Patent 3,256,552 HINGE Bernard Sterner, Paris, France, assignor to Societe Fer-mod S.A., Paris, France, a French body corporate Filed Jan. 23, 1963, Ser. No. 253,329 Claims priority, application France, Feb. 6, 1962, 887,101 7 Claims. (Ci. 16128) The present invention relates to hinges for refrigerator doors and other apparatus or installations, this door being adapted to apply against the fixed support face formed on the body of the refrigeratoror on any other frame with interposition between the door and this face of a sealing element that the closed door must compress against said face.

The required compression for providing a seal is easy to obtain on the side corresponding to the closing lock or latch, which comprises for this purpose elasticallyyieldable means biasing the door against the support face. On the other hand, on the side relating to the hinges, this result has heretofore been obtained in an imperfect manner as most of the known hinges comprise no elasticallyyieldable biasing means and those that do are more com plicated in construction and costly.

The object of the present invention is to remedy these drawbacks.

The invention provides an improved hinge which permits elastically applying the door provided therewith against the fixed support face corresponding to the door and thus compressing a sealing element between the face and the door.

In this improved hinge, the moving part thereof adapted to be fixed to the door comprises a slideway whose plane of symmetry is perpendicular to the corresponding fixed support face of the door in the closed door position, and said moving part slides through the medium of the slideway and in opposition to an elastically-yieldable means, on a slide rotatively mounted on a fixed pin which constitutes a hinge hook or pin and is carried by the part of the hinge adapted to be fixed to said fixed support face.

Owing to this feature, the desired elastic biasing is obtained in a particularly strong hinge having massive parts which are capable of being disassembled and in particular permit the hinge to be taken apart.

Further features and advantages of the invention will be apparent from the ensuing description, with reference to the accompanying drawings to which the invention is in no way limited.

In the drawings:

FIG. 1 is a vertical longitudinal sectional view of a hinge according to the invention for a refrigerator door, the section being taken along line 11 of FIG. 2 intersecting the axis of the hinge pin;

FIG. 2 is a horizontal sectional view taken along line 2-2 of FIG. 1;

FIG. 3 is a partial front elevational view corresponding to FIG. 1, and

FIGS. 4 and 5 are views similar to FIGS. 1 and 2 respectively in the case of an overlapping door pivoted to a door frame.

In the embodiment shown in FIGS. l3, the hinge is adapted for securing a door B to the forward face a of the body A of a refrigerator or like apparatus, this door being required to compressin its closed position a sealing element C along the entire periphery of the cavity b of the body A.

This hinge is composed of two parts or leaves I and ice Fateniecl June 21 pin 5 having an axis XX and being parallel with the face a. This pivot pin 5 can be an interference fitted in the two ears 4 and maintained therein, for example by means of knurling 6.

The moving part II of the hinge is attached to the door B by screws 7 (FIG. 2) and has the general shape of a strip preferably stiffened by ribs and/or flanges and terminating in a head 8 whose dimension 1 (FIG. 1) is slightly less than that of the entrance of the fork constituted by the ears 4 of the fixed part I so that this head can be engaged in this fork.

The head 8 is provided with a throughway aperture 9 extending in a direction parallel with the axis XX and having a rectangular cross-sectional shape but a semicylindrical end portion which is adapted to form a slide way which is symmetrical relative to a plane which coincides with the plane of the section 11, perpendicular to the face a of the door frame, when the door B is in its closed position resting against this frame. This slide- Way is adapted to slide relative to a slide generally indicated by the reference character 10 and rotatively mounted on the hook or pin 5.

This slide 10 is in fact composed of two independen parts disposed in end-to-end relation and each consisting of, on the one hand, a longitudinally extending portion 11 provided with a cylindrical aperture 12 through the medium of which it is rotatively mounted on the pin, Whereas its outer face fits in the semi-cylindrical end portion of the slideway 9 and the adjacent portions of the parallel faces of this slideway, and, on the other hand, a flange or lateral cheek portion 13 interposed between the head 3 of the part II of the hinge and the adjacent faces of the ears 4 of the part I, so as to reduce Wear and friction due to the weight of the door.

It will be observed that the two semi-slides are advantageously composed of plastic, for example superpolyamide, polytetrafiuoroethylene or any other material which is wear resistant and has great strength. These elements can be obtained by pressure moulding.

interposed between the half-slides and the end of the slideway 9 adjacent the base 1 are a number of springs 14 centered by pins 15 and bearing, on the one hand, against said end of the slideway 9 adjacent the base 1 and, on the other hand, against a support plate 16 interposed between these springs and the two parts 11 of the slide 10.

During sealing hinge operation the slide 10 does not participate in the rotational movements about the axis XX of the pin 5 and the part II of the hinge slides, through the medium of its slideway 9, on this slide 10.

In the open position of the door, the slide and slideway occupy the relative position shown in FIGS. 1 and 2, and the same is true in the closed position if the force exerted by the springs 14 exceeds the elastic reaction of the sealing element C.

On the other hand, if the sealing element C offers a resistance when the door is being closed which exceeds the force exerted by the springs 14 which are extended to the maximum extent (illustrated position), these springs are compressed and the part II of the hinge moves toward the left (when viewed as in FIGS. 1 and 2) away from the part I, the slideway 9 sliding relative to the slide 10 and compressing the springs 14.

In this way, one is certain that in the closed position there is always equilibrium between the elastic reaction of the sealing element C and the elastic action of the springs 14 which, in bearing against the fixed pin 5, bias the door B toward the support face a in the direction for compressing the sealing element C.

Owing to the elasticity-yieldable hinge obtained, in the closed position of the door the sealing element C is perfectly compressed throughout the periphery of the door.

As can be seen, the hinge is composed of two massive parts. It can be taken apart since it is sutficient to extract the pin 5.

FIGS. 4 and 5 show avariant of a hinge adapted to pivot the leaf B of an overlapping door, to a door frame A a sealing element C being compressed therebetween.

The part I of the hinge is more or less identical to the part I of the first embodiment.

The part II is shorter than the part II of the first embodiment and secured directly through the medium of lateral lugs 17, to the lateral edge d of the leaf B by means of screws extending through countersunk holes 18.

The rest of the arrangement is identical to the first embodiment, the head 8 of the part II comprising a slideway 9 which is, however, narrowed at 9 so as to guide the springs 14 which are centered by the pins 15 and bear through the medium of the bearing. plate 16 against the two parts of the slide generally indicated by the reference character 10 The longitudinal portions 11 of the two parts of the slide have a rectangular cross-sectional shape corresponding to that of the larger part of the slideway 9.

Although specific embodiments of the invention have been described, many modifications and changes may be made therein without departing from the scope of the invention as defined in the appended claims.

It is obvious that the number of springs can be different from that shown and that any other type of spring could be employed, such as a stack of Belleville washers or a stack of spring blades bent in opposite directions and disposed in the longitudinal direction in the slideway 9.
