DESCRIPTION:
BRIEF SUMMARY
This invention relates to a refrigerator door having a frame of joined parts, an outer shell, an inner door lining and a heat insulation.
Doors which have been in existence for a long time usually have several metal members which are, for example, fabricated of aluminum, as well as various attachment means and special fittings for the door hinges. Many refrigerators are provided with hinge fittings at both vertical sides of the door so that the buyer can choose whether the hinges should be at the right or at the left side of the door. Therefore, special fittings have to be attached to the four corners of the door. Further included are an outer shell, an inner door lining and possibly also special door handles. Such a door calls for much work in assembling all the parts included and in some cases also laquering of the frame in a special device for the purpose. In the latter case additional costs for transport to and from the laquering device and through it are involved. As a result, the door will be comparatively expensive in manufacture.
The object of the invention is to provide a refrigerator door at a lower cost than earlier. This can be achieved according to the invention in a door whose top and bottom frame parts at their ends have a bushing for a pivot pin of a hinge, the bushing being insertible in a sleeve on a side part of the frame.
The invention will be described in detail below with reference to a refrigerator door shown in the drawings.
FIG. 1 is a front view of the door.
FIG. 2 is a vertical section through the door on the line II--II of FIG. 1.
FIG. 3 is a similar vertical section on the line III--III of FIG. 1.
FIG. 4 is a horizontal section through a part of the handle on the line IV--IV of FIG. 1.
FIG. 5 is a horizontal section through the door frame on the line V--V of FIG. 1.
FIGS. 6 and 7 are two different perspective views of one end of a lower or an upper frame part.
FIGS. 8 and 9 are perspective views of each end of a side part of the frame.
FIG. 10 shows an upper frame corner, seen from the front, and
FIG. 11 shows the same frame corner, seen from behind, in both cases without outer shell and inner door lining.
The refrigerator door shown in the Figures comprises a frame with a top part 10, an inverted bottom part 11 of equal shape, a side part 12 to the left and an inverted side part 13 of equal shape to the right. Before these parts are joined a front plate 14 and a handle part 15 are inserted in the frame.
In the vertical section of FIG. 2 the top part 10, the side part 13, the front plate 14 and the handle part 15 are seen. The latter is shown separately in FIG. 4 in which it can be seen that it has a recess 16, 17 which extends obliquely inwards and has a grip edge 18, 19. When the hinges of the door are on the right side, the edge 19 is used to open and close the door and when the hinges are on the left side of the door the edge 18 is used.
On the inner face of the frame a sealing strip 20 is arranged with a flange 21 between an inner frame flange 22 and an inner door lining 23. The sealing strip 20 is elastic and includes in a known manner a magnetic strip 24. The parts are joined, for example by polyurethane which is foamed in situ in the door.
FIG. 3 shows the same parts as FIG. 1 but in another section which extends through the recess 16 in the handle part 15 with grip edge 18.
In FIGS. 6-9 the corners of the door are shown in different views. Thus, FIG. 6 is a perspective view interiorly of the lower left corner or the upper right corner of the door of FIG. 1, and FIG. 7 is the same corner seen from the exterior. Thus it appears from FIG. 7 that the top and bottom frame parts have holes 25 in the frame part 10 or 11 in a part formed as a bearing bushing 26 interiorly of the frame. The bushing 26 is in the shape of a cylinder, the hole 25 being intended to receive a bearing pin. The cylinder has a bottom 27 with an aperture 28. The frame parts are die-casted of a suitable plastics material and are so shaped that the top and the bottom frame parts 10, 11, extend around the
