Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for a refrigerator door in which the door is pivotally supported on the refrigerator body so as to be openable and closable by using adjustable legs that support the refrigerator body on the floor.

In conventional refrigerators, a round bar-shaped hinge pin is fixed by caulking to a mounting bracket fixed to the front of the refrigerator body.
The door is pivoted to this hinge pin so that it can be opened and closed, and support legs separate from the hinge pin are attached to the outer bottom of the refrigerator body.
The support legs supported the refrigerator on the floor.

In this conventional method, it is necessary to separately manufacture and install the hinge pin and the support leg, which requires a large number of parts and is poor in workability. Also, the distance between the rear support leg and the front support leg is narrow, resulting in poor stability. The problem was that it was bad.

To solve this problem, in order to pivot the door so that it can be opened and closed using the adjustable legs that serve as front support legs, the adjustable legs are screwed up and down into a mounting bracket fixed to the front of the refrigerator body. It is conceivable that the upper end of the adjustable leg could support the door so that it can be opened and closed. Also, the weight of the refrigerator body, which has become heavy due to storing a large amount of food, may be applied to the screws, etc. that secure the mounting brackets to the front of the refrigerator body, causing the risk of breakage. This causes a problem.

The present invention was developed in view of the above circumstances, and its purpose is to have the adjustable legs not only have the function of adjusting the height position on the door side of the refrigerator, but also have the function of pivotally supporting the door. Therefore, compared to performing both functions with separate parts, the number of parts can be reduced and the price can be reduced, and the door does not move up and down due to the vertical movement of the adjustable legs, and the screws used to fix the fixtures do not break. To provide a support device for a refrigerator door, which has the effect that there is no risk of damage, the work of installing and removing the door is simple, and the stability of the refrigerator can be improved.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes an entry/exit opening formed on the front surface 2a of the refrigerator body 2, and 3 a door pivotally supported on the peripheral edge of the closing portion 1 by a method described later, which opens and closes the opening 1.

Reference numeral 4 denotes an insertion hole formed at the right corner of the lower surface 3a of the door 3, into which a bushing 5 is fitted from below.

Reference numeral 6 denotes two screw holes formed side by side at the lower right side of the front surface 2a, as shown in FIG.

As shown in FIG. 1, 7 is a substantially U-shaped fixture whose front and left and right sides are open, and the lower surface plate 7a is the lower surface portion of this fixture.
A flange 7b is formed to extend rearward, and a screw hole 8 is formed in the bottom plate 7a and the flange 7b so as to pass through them in common.

In addition, an insertion hole 9 is formed in the upper plate 7C, which is the "-face part, at a position concentric with the screw hole 8, and an insertion hole 10 whose diameter is slightly larger than the screw hole 6 in the rear plate 7a corresponds to the screw hole 6. formed in position.

By tightening the two mounting screws 11 into the screw holes 6 through the insertion holes 10, the mounting tool 7 is attached to the flange 7b.
It is attached to the lower right edge 12 of the opening 1 of the refrigerator main body 2 so as to face the outer bottom surface 2b of the refrigerator main body 2.

Reference numeral 13 denotes an adjustment leg, the lower half of which has a slightly larger diameter than the upper half, and this lower half has a male screw 14 that is screwed into the screw hole 8.
Further, a large-diameter flange portion 15 is formed at the lower end of the adjustment leg 13 as an abutting portion.

Therefore, when supporting the door 3 on the refrigerator main body 2, with the fixture 7 attached to the front surface 2a, the door 3 is supported on the top surface of the top plate 7C of the fixture 7 via the bushing 5. .

Next, insert the upper shaft part 13a of the adjusting leg 13 into the lock nut 16 provided on the screw hole 8 and the bottom plate 7a from below, and then insert the male screw 14 into the screw hole 8 and the lock nut 16. Screw together so that it can be screwed back and forth.

Then, by further screwing in the adjusting leg 13, the adjusting leg 1
3, the shaft portion 13a is caused to protrude above the top plate 7C, and the shaft portion 13a is inserted through the bushing 5 into the insertion hole 4 so as to be vertically movable.

In this state, that is, when the shaft portion 13a is inserted into the door 3, the flange portion 15 of the adjustment leg 13 comes to protrude downward by a predetermined length from the outer bottom surface 2b of the refrigerator main body 2, as shown in FIG. .

Furthermore, although not shown, a simple round bar-shaped hinge pin, unlike the adjustment leg 13, is inserted through a bushing into an insertion hole formed on the top surface of the door 3 to correspond to the insertion hole 4, and as follows. The door 3 is removably pivotally supported on the periphery of the opening 1.

As a result, the opening 1 can be opened and closed by rotating the door 3 laterally.

Finally, a U-shaped cover 17 is fitted onto the fixture 7 from the outside to improve its appearance.

Therefore, when the refrigerator 2 is installed on the floor surface 18, the flange portion 15 of the adjustment leg 13 that protrudes downward by a predetermined distance from the aforementioned outer bottom surface 2b comes into contact with the floor surface 18 as shown in FIG. , that is, the length dimension of the adjusting leg 13 is
The adjustment leg 13 has a length that reaches the floor surface 18 from a to the floor surface 18, and thus the adjustment leg 13 fulfills the supporting function of supporting the refrigerator body 2 in the same way as the support legs conventionally attached to the outer bottom surface 2b of the refrigerator body 2. .

If the refrigerator main body 2 is even slightly inclined with respect to the floor surface 18, after loosening the lock nut 16, by rotating the collar 15 of the adjusting leg 13, the male screw 14
The height of the refrigerator main body 2 on the door 3 side is adjusted by screwing it forward and backward into the screw hole 8 of the fixture 7.

When the refrigerator main body 2 is now in a horizontal state with respect to the floor surface 18, the lock nut 16 is tightened until it comes into contact with the upper surface of the lower surface plate 7a, thereby completing the installation of the refrigerator main body 2.

In this way, according to this embodiment, the refrigerator main body 2 is placed on the floor surface 18.
When the refrigerator is installed at an angle, the refrigerator can be opened by simply rotating the flange 15 of the adjustable leg 13 that pivotally supports the door 3 from side to side and screwing the male screw 14 forward and backward into the screw hole 8. The height position of the main body 2 on the side of the door 3 can be adjusted arbitrarily, so that the refrigerator main body 2 can always be installed horizontally with respect to the floor surface 18.

In this case, the door 3 is supported by the two-face plate 7C of the fixture 7, and the shaft portion 13a of the adjusting leg 13 is inserted into the insertion hole 4 of the door 3 via the bushing 5 so that it can move up and down. As the adjusting leg 13 moves up and down by screwing forward and backward, the door 3 moves toward the refrigerator body 2.
It does not go up or down.

In addition, the adjustable legs 13 support both the door 3 and the refrigerator body 2.
The number of parts can be reduced and the parts can be easily managed, and the work of installing the parts can also be done easily, greatly improving work efficiency compared to the conventional method in which each part is made as a separate part. can be improved.

Furthermore, since the adjustment legs 13 are located below the door 3, the distance between them and the rear support legs can be made longer than in the past, and the stability of the refrigerator main body 2 can therefore be increased.

Therefore, even if a large amount of beer bottles or other extremely heavy items are stored in the inner pocket of the door 3, the refrigerator body 2 will not tilt and will remain in a horizontal state even if the door 3 is opened all at once. keep.

Furthermore, since the flange portion 15 of the adjusting leg 13 directly supports the heavy object, it is possible to prevent the support device of the door 3 from being damaged.

Moreover, since the flange 7b that protrudes backward is formed on the fixture 7, and this flange 7b is directed against the outer bottom surface 2b of the refrigerator main body 2, the heavy refrigerator main body 2 can be directly supported by the flange 7b. It is possible to prevent inconveniences such as a large load being applied to the mounting screws 11 for fixing the mounting tool 7 and causing them to break.

In addition, in this embodiment, even if the door 3 is damaged and needs to be replaced, for example, it is not possible to replace the door 3 due to the fact that it is attached by caulking the hinge pin. In comparison, the door 3 can be removed from the refrigerator body 2 by simply loosening the lock nut 16, screwing back the adjusting leg 13, and pulling it out from the insertion hole 4.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the invention.

As explained above, the present invention has a substantially U-shape, and has an insertion hole corresponding to the insertion hole of the door formed on the upper surface, and a screw hole concentrically with this insertion hole on the lower surface, and a screw hole at the rear. A fixture is formed by forming a protruding flange, and is attached to the main body so that the flange faces the outer bottom surface of the main body and receives the door at the top surface, and a fixture is attached to the bottom end to face the floor surface. The shaft part of the upper part has an abutment part and is vertically movably inserted into the insertion hole of the door through the insertion hole of the fixture, so that the male screw of the lower part is pivotally supported so that the iron door can be opened and closed. By providing an adjustable leg that is screwed into the screw hole of the fixture so that it can be screwed forward and backward, the adjustable leg not only has the function of adjusting the height position on the door side of the refrigerator, but also has the ability to pivot the door. It has a support function, and therefore the number of parts can be reduced and the price can be reduced compared to the case where both functions are performed by separate parts.In addition, the door can be moved up and down with respect to the main body by the vertical movement of the adjustable legs. There is no risk that the screws for fixing the mounting bracket will break due to the load of the heavy refrigerator. The space between the support legs is also widened, which has the effect of improving the stability of the refrigerator.
