Abstract

PURPOSE:To prevent a door from hanging-down by providing a roller at the lower end of a grip side of an upper door so that it is capable of moving forward and backward, and providing a recess fitting to the roller to a hinge for opening and closing the lower door. CONSTITUTION:In the case of closing of an upper door 8, when a grip side of the door 8 is hung down, a roller 16 guided by an inclination to that side formed in the front end of a hinge 12 is pushed up against a coil spring 15. After that, when the door 8 is closed, the roller 16 pushed up falls in a recess 18a provided on the top of a hinge shaft 18 of the hinge 12 pivoted on the lower door.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a refrigerator in which the free end of a wide upper door is supported by a hinge of a narrow lower door arranged directly below the free end of the wide upper door. This invention relates to a door support device.

[Prior Art] FIG. 6 is a perspective view of a refrigerator shown in Japanese Utility Model Application Publication No. 55-59285, and FIG. 7 is an exploded perspective view of the main parts of FIG. 6. In these figures, (1) is the refrigerator body, (2
) is the upper door, (3) is the lower door, (4) is the front plate located between these two doors, (5) is the periphery of the refrigerator body, (6)
is the hinge attached to the right end in the front panel diagram above, (6
a) is a hinge shaft, (6b) is a hinge seat, and (7) is a hinge mounting screw.

That is, the upper half of the hinge shaft (6a) is inserted into the upper part B (2), and similarly the hinge shaft (6a) is inserted into the lower door (3).
By inserting the lower half of both doors (2) (3
) is rotatably supported.

[Problems to be Solved by the Invention] As described above, conventional door support devices are supported on a cantilever by the hinge shaft, so they tend to sag especially on the handle side due to the load. ,
As the number of wide doors increases, the sagging of these doors becomes more noticeable.

This invention was made to solve the above problems, and its purpose is to suppress the drooping of the door.

[Means for Solving the Problems] As an embodiment of the refrigerator door support device according to the present invention, a roller is embedded in the lower end surface of the handle side of a wide upper door so that it can move forward and backward, and the lower half of the roller is embedded. is elastically inserted and locked into a recess provided on the top surface of the hinge of the lower door arranged directly below the upper door when the upper door is closed.

[Function] In the embodiment of the present invention, on the handle side of the upper door, the lower half of the roller embedded in the lower end face thereof so as to be able to advance and retreat freely is supported by the hinge of the lower door directly below it, so that the upper door is In the closed state, it is supported at both ends, so that the free end on the handle side does not sag.

[Example] An example of the present invention will be described below. That is, in Figure 1, (8) is a wide upper door, (9) (10
) is a narrow lower door installed directly below it, (11) is a hinge for supporting the upper door (8) and one of the lower doors (10) at the same time, and (12) is the other lower door ( 9), (13) is the rotating handle of the upper door. 3 In Figures 2 to 4, (14) is the four parts provided on the lower end surface of the upper door (8) on the handle side. Then, a coil spring (15) and a roller (16) are placed inside it, and these are covered by a box (17) from below, and the lower half of the roller (16) is inserted through a round hole (17a) on the bottom of the bracket box. stands out.

FIG. 5 is a sectional view taken along the line ■-■ in FIG.
The above roller (
A recess (18a) into which the lower half of 16) is elastically inserted and locked.
) is formed.

Next, the operation will be explained. The rotation support end side of the upper door (8) is pivotally supported by a hinge (11), and a box (17) is provided in the recess (14) on the lower end surface of the handle side on the opposite side.
The roller (1) resists the coil spring (15).
6) is provided to move forward and backward, and the lower half of this roller (16) protrudes from the bottom round hole (17a) of the box (17), and when the upper part N (8) is closed, the lower half of the roller (16) ) is fitted and locked into the recess (18a).

Therefore, when the door is closed, if the handle side (1
3) is lowered, the roller (1
6) is pushed up against the coil spring (15). And the pushed up roller (16) is the upper door (8)
When closed, it falls into the recess Cl8a) provided on the top surface of the hinge shaft (18) of the hinge (12), thereby positioning the upper door (8) at that position.

In the above embodiment, the roller is embedded in the lower end of the upper door on the handle side, but the roller may be embedded in the hinge side, and the coil spring may be housed in the hinge shaft.

[Effects of the Invention] Since the refrigerator door support device of the present invention is configured as described above, it is possible to suppress the hanging of the wide upper door in the closed state, and the refrigerator door support device of the present invention can be prevented from sagging when the wide upper door is closed. Does not spoil the appearance
