Definitions

  • the present invention relates to a hinge for French doors in a refrigerator. More precisely, the invention relates to a hinge according to the preamble of Claim 1.
  • French doors are opposite doors covering the opening, without a post between them.
  • the seals of the doors must not rub against each other during the opening of both of the doors, or only one of the doors. Rubbing would cause wear of the seals and would make the opening of the doors more difficult.
  • the hinge should be of small dimensions and in particular such that the hinge will not protrude beyond the - side-wall plane.
  • the hinge should be easy to use and reliable in such a manner that the door will open and close easily and, beyond a certain angle of opening, it will remain open by it ⁇ self and, respectively, will close rapidly when the opening angle has reached a sufficiently small angle.
  • the hinge should be durable, allowing the door to be opened completely, i.e. through almost 270°.
  • This hinge is a relatively large- sized structure and therefore esthetically poor. It extends in the lateral direction of the refrigerator beyond the plane of the side wall and also protrudes from the frontal plane of the refrigerator.
  • the yielding movement i.e. the lateral com ⁇ ponent of the movement, is effected with the aid of a notch in the swiveling part of the hinge so that the notch will guide the path of movement of the door, a guide roller in the hinge frame sliding in this notch.
  • the swiveling part turns about a pin which is at the end of an arm attached to a spring.
  • the object of the present invention is to provide for French doors in a refrigerator a hinge from which the above dis ⁇ advantages have been eliminated.
  • the hinge structure according to the invention is small- dimensioned and esthetically pleasing. When installed in place it does not protrude beyond the side plane or the frontal plane of the refrigerator. It is strong and enables the doors to be opened through an angle ranging from 0 to 270° without the hinge giving in, or yielding, and thereby straining the structure.
  • the hinge is easy to open and close. The first, primarily lateral opening phase is rapid. After the first opening phase the hinge is stationary and the door pivots only about the hinge pin. The last, primarily lateral closing phase occurs rapidly with the additional effect produced by the spring. The opposite door remains closed, if so desired, while one door is being opened.
  • Figure 1 depicts a top plan view of the hinge frame for the lower edge of the door.
  • Figure 2 depicts, from the side turning to face the hinge frame, the swiveling part which attaches the door and con ⁇ stitutes part of the hinge frame depicted in Figure 1
  • Figure 3 depicts the hinge parts depicted in Figure 1 and Fig ⁇ ure 2, interconnected in the operating position.
  • Figure 4 depicts a front view of the combination according to Figure 3,
  • Figure 5 depicts the frame and swiveling part of a hinge for the upper edge of the door, interconnected in the operating position.
  • Figures 6a, 6b and 6c depict a hinge according to Figure 3, attached to the lower edge of a door, in operation, i.e. a) in the closed position, b) slightly before the extreme position of the phase of lateral movement, and c) with the lateral movement locked, the door opening freely.
  • Figure 7 depicts a separate latch part made of thermosetting plastic
  • Figure 8 depicts a separate slide made of thermosetting plastic.
  • the frame and swiveling part of the hinge are preferably made of a pressure-casting mix and the separate parts, such as the latch, the slide and the roller, of thermosetting plastic.
  • the frame of the lower-edge hinge depicted in Figure 1, is indicated by reference numeral 1.
  • the notch which renders to the roller in the door a lateral component of movement is in ⁇ dicated by numeral 2,
  • the said roller is indicated by 3.
  • the pin 6 of the swiveling part 21 is fitted in a hole 5 in the hinge frame and serves as the pivot axis for the swiveling part.
  • the P-shaped groove 7 in the frame is intended for re ⁇ closing the load-lightening spring 8 of the hinge.
  • the frame has a lower surface and an upper surface, between which the notch 2 is formed. In the end receiving the swiveling part there is only the lower surface, the swiveling part forming a surface in the same plane as the upper surface.
  • the swiveling part is attached to the frame by means of the pin 6 and to the door by means of a pin 22.
  • the maximum dimensions of the as ⁇ Sild hinge are: approx. 35 mm deep, approx. 105 mm wide, and approx. 17.5 mm high. In the height dimension, the attach ⁇ ing height of the attaching wall makes up approx. 4.5 mm.
  • the hinge structure has as its essential parts a separate slide 9 and a spring 10 acting on it, as well as a latch 11 with its spring 11a.
  • the slide 9 is in a location fitted in the lower surface of the frame, between one of the vertical walls and the guides 12 and 13 opposite that wall, and is cap ⁇ able of reciprocating in its own longitudinal direction, guid ⁇ ed by the guides.
  • the lower surface of the frame also has a pin 14, which serves as a limiter and mates with an opening 15 in the slide.
  • the latch 11 with its spring is located in the swiveling part 21, in the vertical partition wall 16 of which there is a notch corresponding to the latch end and a concave arch corresponding to the spring 11a of the latch.
  • the slide has a bore 17, parallel to the direction of movement of the slide, into which bore one end of the spring 10 loading the slide is fitted.
  • the length and rigidity of the spring have been adjusted so that the spring will be compress between the slide bore 17 and the stop 12 meeting the other end of the spring.
  • the other end of the latch has been fitted to extend, in the closed position of the door, somewhat beyond the said stop 12; see Figures 3 and 6a.
  • That end 18 of the slide which faces the notch is cam-shaped and protrudes in the closed position of the door so much into the notch area that the roller 3 will touch the ob ⁇ lique surface inside the cam. Simultaneously the roller 3 will touch the opposite wall of the notch 2, which wall forms an ⁇ other cam 19, but in the opposite direction.
  • the door is free to open through up to 270°, and owing to the said latch solution, moving even a heavily loaded door within the opening range 0 - 270° will not strain the hinge detri ⁇ mentally.
  • the slide 9 will be pushed to the left (from the situation of Figure 6c), the front end 20 of the slide sliding along the shaped arm of the latch.
  • the roller is at the cam peaks 18 and 19 the slide has detached the latch end from the stop 12 by pushing, whereupon the swiveling part is free to pivot counterclockwise under the effect of the closing movement.
  • the closing movement is enhanced and sped up by the slide 9, which pushes out to behind the roller and closes the door in a moment, thereby increasing the closing force.
  • the rapid closing is also promoted by the magnet generally used in the seals. The closing, of course, takes place primarily from the side, as does the opening, and so no rubbing of the seals will occur in connection with the closing.
  • the spring 8 depicted in Figure 3 is used only in the lower hinge of the door, where the weight of the door loads the hinge. It is intended for lightening the load, but is not in ⁇ dispensable. It is not used in the upper hinge of the door, as is evident from Figure 5.
  • the lower and upper hinges function in principle in exactly the same manner. However, there are nonessential additional differences between their structures, mainly owing to their different locations.
  • the openings in the upper and lower sur ⁇ faces of the hinge are covered with cover plates.
  • Figure 5 depicts a limiter plate 23, which is fastened to the swiveling part by means of a screw.
  • the cover plate 24, covering the latch, the slide and the spring, is attached to the frame by means of a screw.

Abstract

Articulation pour portes à deux battants de réfrigérateur. Le problème avec une articulation de ce genre est que les portes opposées devraient, sans support intermédiaire, ouvrir en s'écartant afin que les éléments d'étanchéité des portes ne frottent pas l'un contre l'autre. L'articulation prévue rend un tel écartement possible, tout en étant résistante et de petites dimensions, et rend possible un mouvement d'ouverture rapide et un mouvement de fermeture rapide et amélioré. L'articulation comprend une encoche (2) et un rouleau (3) qui coopèrent afin d'assurer un mouvement latéral dirigé. L'encoche est située dans le cadre (1) de l'articulation et le rouleau est situé aux bords supérieur et inférieur de la porte. L'articulation comprend également une glissière (9) à ressort qui reçoit son mouvement de va-et-vient du rouleau, ainsi qu'un élément (11) de verrouillage guidé par glissement destiné à caler l'articulation dans le sens latéral pendant que la porte pivote librement.
