Description

The present invention relates to a storage, particularly to a storage provided with a drawer-type container.

(B) Conventional technology Conventional storages, especially refrigerators, for example,
As shown in JP-A-55-3280, a container having an upper opening is supported by a sliding plate attached to a door, a roller on the main body side abuts on the sliding plate, and a sliding plate on a rail on the main body side. The rollers engage to allow the door to be pulled out with the container.

(C) Problems to be Solved by the Invention In the configuration described in the above publication, the lower end of the sliding plate is bent outward, and the roller on the main body side is slidable on the overhanging piece formed by bending downward. Is in contact with Therefore, in such a configuration, there is only a position regulating piece outside the roller, so that the sliding plate cannot be restricted from moving outward, and the sliding plate and the door are pulled out obliquely, and each roller slides smoothly. Not
There was a problem that the drawer was troublesome. Also, in order to prevent this, when it is attempted to form regulating pieces positioned on both sides of the roller on the main body side, in the configuration of the above publication, the lower end of the sliding plate is folded upward, bent outward, and further downward. There was a drawback that it had to be bent in a complicated manner such as bending.

The present invention has been made to solve such a problem.

(D) Means for Solving the Problems The present invention provides a main body side rail attached to both side walls of a heat insulating box main body that opens forward, a main body side roller mounted front of the main body side rail, and an opening of the heat insulating box main body. A container-side rail that is mounted to extend rearward from the back surface of the door that closes the container, and that is disposed apart from the inside of the main-body-side roller, a container that is supported by the container-side rail, and a lower rear portion of the container-side rail. A container-side roller attached thereto, wherein the container-side rail has, at an upper edge thereof, an inner piece bent and formed close to an upper portion of an inner side surface of the main-body-side roller, and an outer piece from the inner piece. A horizontal piece bent substantially at right angles to the direction, and a downwardly-opening groove formed from an outer piece bent downward along the outer surface of the body-side roller from the horizontal piece. The width of the bottom of the concave groove is larger than the width of the main body side roller. A little bigger,
The container-side roller is mounted on the main-body-side rail, and the container-side rail is mounted on the main-body-side roller with a horizontal piece of the concave groove, so that the container can be pulled out of the heat-insulating box main body. This is the configuration of the storage.

(E) Function According to the present invention, the movement of the container-side rail to the left and right can be restricted by a simple structure.

(F) Example Next, an example will be described with reference to the drawings. FIG. 1 is a schematic longitudinal sectional view of a refrigerator (1) to which the present invention is applied.
An inner box (3) is engaged at an interval in the outer box (2) opening forward, and a foamed heat insulating material (4) such as polyurethane is filled in the interval by an in-situ foaming method. A heat-insulating box main body (5) that opens to the inside is formed. The inside of the main body (5) is vertically divided by a heat insulating partition wall (6), and a freezing compartment (7) is formed above. The lower part of the heat insulating partition wall (6) is further partitioned into three chambers by partition plates (8) and (9), and the uppermost chamber is a refrigerated chamber (10). A cooler (11) is provided in the heat-insulating partition (6), and cool air cooled by the cooler (11) is blown into the freezing room (7) by the blower (12) from the discharge port (13).
Further, each of the chambers (7) and (10) is cooled to a predetermined temperature by discharging from a discharge port (not shown) to the refrigerating chamber (10). (14),
(15) is a door that opens and closes each of the rooms (7) and (10).

Between the partition plates (8) and (9), an upwardly opening ice temperature container (17) is disposed, and below the partition plate (9), an upwardly opening vegetable container (18) is disposed. Ice greenhouse (20)
And vegetable room (21). (22) and (23) are doors for closing the space front opening between the partition plates (8) and (9) and below the partition plate (9). Container-side rails (24) and (24) extending rearward are attached, and each of the containers (17) and (18) is a container-side rail (24).
Supported by (24). Container-side rollers (26) and (26) are attached to the rear of the container-side rails (24) and (24). In addition, the inner box (3) has both sides of the main body rail (2
7) and (27) are mounted, and the main body side rollers (28) and (28) are further mounted on the inner box (3) in front of them. Part of the cool air from the blower (12) is the outlet (29)
And is supplied to the lower part of the partition plate (8) through the duct (30). The amount of air blown out from the discharge port (29) is adjusted by opening and closing the discharge port (29) with a damper (31) that detects the temperature in the ice greenhouse (20). ° C
To maintain. Further, the inside of the vegetable room (21) is cooled by cold air descending from the partition plate (9).

FIG. 2 is an enlarged cross-sectional view of the container-side rail (24) of the door (22) (the same applies to the container-side rail (24) of the door (23) hereinafter). The inner box (3) has a substantially U-shaped cross section open to the front and the inner box (3).
And is held between the convex portions (33) and (33) formed in the above. The body-side roller (28) is attached to the inner box (3) above the body-side rail (27) at a horizontal position by a shaft screw (28a). Also, the container side roller (26) is also a shaft screw (26a).
Is fixed to the lower rear part of the container side rail (24). The container-side rail (24) is made of a relatively thick long steel plate, and the upper edge of the container-side rail (24) is slightly shifted in parallel to the outside,
Then, a horizontal piece (36) bent outward at a substantially right angle and an outer piece (37) bent further downward are formed, and these pieces (35), (36) and (37) form a lower part. A concave groove (38) that opens to the outside is formed. The width of the lower surface of the horizontal piece (36), that is, the width of the bottom of the concave groove (38) is slightly larger than the width of the body-side roller (28). The container (17) is supported by placing the rib (40a) at the lower end of the upper edge flange (40) on the horizontal piece (36).
In this state, the container side roller (26) is slidably engaged with the main body side rail (27), while the main body side roller (28) is engaged in the concave groove (38) on the upper edge of the container side rail (24). Then, it is slidable by contacting the bottom. This allows the door (22) to be
It can be pulled out from the body (5) together with 7).

At this time, the positional deviation between the container-side rail (24) and the body-side roller (28) in the left-right direction is restricted within the width of the concave groove (38), so that the container-side rail (24) and the door (22) are inclined. The rollers (26) and (28) slide smoothly on the base rail (27) and the bottom of the concave groove (38).

(G) Effects of the Invention According to the present invention, the container-side rail has, at its upper edge, an inner piece bent to approach the upper part of the inner side surface of the main body-side roller, and an outer piece from the inner piece. A horizontal piece bent substantially at right angles to the direction, and a downwardly-opening groove formed from an outer piece bent downward along the outer surface of the body-side roller from the horizontal piece. Since the width of the bottom of the concave groove is slightly larger than the width of the main body side roller, stable mounting is possible, and even if the container side rail is inclined with respect to the main body side roller, There is no locked state of the main body side roller due to the engagement between the side roller and the container side rail, and a configuration with low pull-out resistance can be achieved.

Further, since the formation of the concave groove is achieved by simple bending, the assembling workability is improved, and the cost can be reduced.
