Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a door that can be opened to the left and right in a refrigerator.

(Prior Art) Conventionally, a single-door refrigerator door has been generally provided on the market, but in recent years, a door that can be opened on both sides has been provided to meet various needs of users. Is becoming.

However, the door that can be opened on both the left and right sides may be tilted slightly when viewed from the front due to its own weight when opened. Therefore, in order to close the door in a slightly tilted state in a normal horizontal state with respect to the refrigerator body, there is a door provided with a posture correction roller at a predetermined position. This is because when the door is closed, this roller is rotatably slid on the partition in the refrigerator to correct the door so that it is in a horizontal state, and the door is closed in a normal horizontal state with respect to the refrigerator body. It was done like this.

Examples thereof are shown in FIGS. 3 and 4. The roller a, which is rotatably slid on the partition H of the refrigerator, is rotatably attached to the tip arms c and c of the roller mounting body b by using the connecting pin d. A support plate g having a U-shape in plan view in which pin insertion holes f, f are formed in the lower part of the side pieces e, e whose both edges are raised in the forward direction, and a screw hole h which is L-shape in side view and is drawn at the bottom. And the reinforcing plate j having the rising side pieces i, i provided on both side edges are the back portions k, 1 and the rising side pieces e, e,
i and i were fixed by spot welding at a total of 3 places.

Further, the support plate g and the roller mounting body b are mounted on their side portions by the connecting pins m, and the reinforcing plate j and the roller mounting body are mounted by the two adjusting screws n and p for adjusting the vertical position of the roller a. It was fixed with b.

The support plate g and the reinforcing plate j were fixed to the door body q with screws r and r.

(Problems to be solved by the invention) However, as described above, the supporting plate g and the reinforcing plate j are welded and fixed at three points, the roller mounting body b is mounted on the supporting plate g, and the roller is moved up and down with two adjusting screws. Since the position adjustment and the fixing of the reinforcing plate j and the roller mounting body b are performed, there is a problem that it takes time to mount each component. Further, since spot welding is required and a reinforcing plate j is required in addition to the support plate g and the roller mounting body b, there is a problem that the cost becomes high.

An object of this invention is to solve the above-mentioned conventional problems. That is, the reinforcing plate can be eliminated as compared with the conventional one described above, further, spot welding is not required, and the fixing of the support plate and the roller mounting body can be simplified, which contributes to cost reduction. It is intended to provide a door that can be opened to the left and right in a refrigerator that can operate.

(Means for Solving the Problem) In order to solve the above problems, the present invention makes a door horizontal by rotating and sliding a roller provided at a predetermined position of a door on a partition part in a refrigerator. The roller is rotatably attached to an arm protruding from one end of the roller mounting body by means of a pivot pin so that the roller can be supported from a position near the back of the bottom of the L-shaped side view support plate. An arm protruding from the other end of the roller mounting body is pivotally supported by a connecting pin on the hanging protruding piece, and the roller mounting body is mounted on the bottom portion of the support plate by a screw with a nut. Is fixed to a predetermined position of the door body.

(Operation) Therefore, the reinforcing plate in the above-mentioned conventional one is eliminated, spot welding is not required, and the fixing of the support plate and the roller mounting body is simplified.

The operation will be described. The roller provided on the door is rotatably slid on the partition of the refrigerator, and when the door is closed, the posture of the door is corrected to a horizontal state.

(Embodiment) An embodiment of a door that can be opened to the left and right in a refrigerator according to the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a main part of a refrigerator according to the present invention after the doors that can be opened to the left and right sides are assembled, and FIG. 2 is an exploded perspective view of the main part.

The left and right doors of the refrigerator according to the present invention can be opened,
A refrigerator (not shown) is provided with a row 2 provided at a predetermined position of the door body 1.
It is supported in a horizontal state by rotating and sliding on the inner partition H.

The roller 2 is rotatably pivoted by a pivot pin 4 to both forearm portions 32, 32 which are vertically projected horizontally at one end of a U-shaped body portion 31 of the roller mounting body 3 in a front view. It is worn.
Numerals 321 and 321 are provided in both forearm portions 32 and 32, and are through holes for inserting the pivot pins 4.

On the other hand, a protruding piece 54 hangs down from a portion near the back portion 53 in the bottom portion 52 of the L-shaped support plate 5 having the reinforcing pieces 51, 51 erected on both side lines in a small size.

By the connecting pin 6, both rear arm portions 33, 33 vertically projecting horizontally with the tip end squeezed to the other end of the body portion 31 of the roller mounting plate 3 are connected to the projecting piece 54 of the support plate 5 by the connecting pin 6. It is pivotally supported.
Reference numerals 331 and 331 are pin insertion holes provided in both rear arm portions 33 and 33,
541 is a pin insertion hole provided in the protruding piece 54, and the connecting pin 6 is inserted into these pin insertion holes 331, 331, 541.

The roller mounting body 3 has a nut 52 on the bottom 52 of the support plate 5.
Mounted by. That is, the nut-equipped screw 7 is inserted into the through hole 311 provided in the substantially central portion of the body 31 of the roller mounting body 3, and the drawn screw hole 521 provided in the bottom portion 52 of the support plate 5 is provided with the nut-equipped screw 521. The screw portion of 7 is screwed together, and the vertical position of the roller 2 can be adjusted by advancing and retracting the screw 7 with nut.

Then, as shown in FIG. 1, the back portion 53 of the support plate 5 is fixed to a predetermined position of the door body 1 (a position at substantially the same height as the partition H in the refrigerator) with mounting pins 8 and 8. .

With the above configuration, when the door is closed, the roller 2 provided on the door body is rotatably slid on the partition H in the refrigerator, and the posture of the door is corrected to a horizontal state.

(Effect of the Invention) As described above, according to the present invention, the roller is rotatably attached to the arm portion protruding from one end of the roller mounting body by the pivot pin, and the roller is attached to the bottom portion of the L-shaped support plate in a side view. An arm protruding from the other end of the roller mounting body is pivotally supported by a connecting pin on a projecting piece hanging from a portion near the back portion, and the roller mounting body is attached to the bottom of the support plate by a screw with a nut. Since the back part of the support plate is fixed to a predetermined position of the door body, the following effects can be obtained.

That is, the reinforcing plate can be eliminated as compared with the conventional one described above, further, spot welding is not required, the fixing of the support plate and the roller mounting body can be simplified, and it contributes to cost reduction. be able to.
