Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a storage, and more particularly to a storage provided with a pull-out container.

(B) Conventional technology In conventional storages of this kind (especially refrigerators), as shown in, for example, Japanese Utility Model Publication No. 60-55981 (Japanese Utility Model Publication No. 63-26714), a container rail with a container having an upper opening attached to a door is used. It is supported by a member, the roller on the main body side abuts on the rail portion provided at the lower portion of the rail member, and the roller on the container side engages with the rail member on the main body side, so that the door and the container can be drawn out.

Furthermore, in order to prevent the door and the container from falling off when pulling out the door vigorously, a stop piece is formed at the rear end of the container rail member, and when the door is pulled out after overcoming the stopper of the container rail member, the stop piece is pulled out. The door contacts the roller on the main body side to prevent the door from falling off due to an inadvertent pulling operation of the door.

(C) Problem to be Solved by the Invention In the above publication, since the rail portion is formed in the lower portion of the container rail member, the stop piece located at the rear end of the container rail member is an extension line of the rear end of the rail portion. If the container rail member is pulled out to the rear end, the main body side roller and the stop piece can be reliably brought into contact with each other when the container rail member is pulled out. The vertical dimension must be larger than the roller diameter. On the other hand, when attaching or removing the container rail member to the refrigerator, the stop piece must pass above the roller on the main body side, but the longer the vertical dimension of the stop piece is, the more this installation or removal work is performed. It gets harder. On the other hand, if the vertical dimension of the stop piece is made shorter than the radius of the roller in consideration of workability, the roller easily gets over the stop piece due to the momentum when pulling out the container rail member, and the container rail member is separated from the roller on the main body side. There was a problem that it was easily dropped. Further, since the main body side roller is provided below the two convex portions, the portion supporting the opening edge of the container of the upper surface opening of the container side rail member and the portion mounted on the main body side roller are vertically arranged. Since the vertical dimension of the container-side rail member is increased as a result, the material area required to form the container-side rail member is increased, and waste of materials and material costs cannot be suppressed, and the volume of the container is reduced. There was a problem that it became smaller.

Therefore, it is an object of the present invention to provide a storage cabinet in which the vertical dimension of the container side rail can be reduced, the shaft length of the main body side roller can be shortened, and the width dimension of the container can be increased.

(D) Means for Solving the Problems The present invention is directed to a main body side rail mounted between two protrusions formed on both side walls of a heat insulating box main body having a front opening, and in the vicinity of the opening of the heat insulating box body, The main body side roller mounted above the convex portion of the strip, the container side rail extending rearward from the back surface of the door that closes the opening of the heat insulating box, and the container side rail mounted on the lower rear part of the container side rail. A container-side roller that slidably engages with the body-side rail, a rail portion that is formed in the front-rear direction in the upper portion of the container-side rail, and on which the lower surface of the body-side roller slides, and a rear end of the rail portion. A storage provided with a stop piece which is positioned rearward and extends vertically and is formed on the container-side rail, wherein the rail portion supports an opening edge of the container having an upper surface opening at its upper surface and a rear end thereof. Between the main body side roller and the stop piece Is larger than the radius and smaller than the diameter, and when the container-side rail is pulled out to the rear end, the container-side roller disengages from the main-body-side rail and the main-body-side roller enters into this interval. It was done like this.

(E) Action Since the lower surface of the rail portion 38 is placed on the main body side roller 28 and the upper surface thereof supports the opening edge of the container 18, the rail portion 38 is placed on the portion supporting the opening edge of the container and the main body side roller as in the conventional case. The vertical dimension of the container side rail 24 becomes smaller than before, and the waste of material of the container side rail can be suppressed and the material cost can be reduced, while the main body side rail 27 is attached. It is possible to reduce the distance between the upper convex portion of the convex portion 33 of the strip and the lower end of the stop piece 42 formed on the container side rail, shorten the shaft length of the main body side roller 28, and reduce the container 18 The width of the container can be increased to increase the volume of the container, and the material cost of the main body side roller can be reduced. Further, a space 43 having a size larger than the radius of the main body side roller 28 and smaller than the diameter is formed between the rear end of the rail portion 38 and the stop piece 42, and when the container side rail 24 is pulled out to the rear end. Since the container side roller 26 is disengaged from the main body side rail 27 and the main body side roller 28 is inserted into this space 43, the container side rail 24 is relative to the main body side roller as much as the main body side roller 28 is in the space. While moving downward, the stop piece with the main body side roller entering the gap
As it abuts against 42, the main body side roller and the container side rail are reliably stopped, and further pulling out operation of the door is prevented. At this time, the main body side roller 28 is prevented from moving (rotating) in the front direction of the container side rail 24 at the rear end of the rail portion 38, and is prevented from moving (rotating) in the rear side direction by the stop piece 42. Therefore, the front-rear movement of the container-side rail 24 is reliably prevented by this interval. Especially the container side rail 24 is the main body side roller
Since it moves downward with respect to 28, the vertical size of the stop piece 42 can be reduced by at least the distance moved downward, and the material cost of the container-side rail is further reduced.

On both side walls of the inner box (3), front and rear body side rails (27), (2
7) is attached and the inner box (3) in front of it
Body side rollers (28), (28) are attached near the opening. Part of the cool air from the blower (12) is the discharge port (29)
It is discharged and is supplied below the partition plate (8) through the duct (30). The amount discharged from the discharge port (29) is adjusted by opening and closing the discharge port (29) with a damper (31) that detects the temperature inside the ice greenhouse (20), and the ice greenhouse (20) is kept at 0 ° C to -3. ℃
To maintain. In addition, the inside of the vegetable compartment (21) is cooled by the cold air falling from the partition plate (9).

FIG. 2 shows an enlarged cross-sectional view of the container-side rail (24) portion of the door (23) (hereinafter, the container-side rail (24) portion of the door (22) is also the same.) The main body-side rail (27) is The inner box (3) has a substantially U-shaped cross section that is open to the front and the inner box (3).
It is held between the convex portions (33) and (33) formed on the. The body side roller (28) is attached to the inner box (3) above the body side rail (27) at a horizontal position by means of a shaft screw (28a). In addition, the container side roller (26) also has a shaft screw (26a)
It 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 has an inner piece (35) on its upper edge with a slight parallel movement outward.
Then, a horizontal piece (36) bent outward at a substantially right angle and an outer piece (37) bent further downward are formed by bending, and these pieces (35), (36) and (37) are used to make downward movement. A rail portion (38) in the form of a groove that opens to the inside is formed. Horizontal piece (3
6) The width of the bottom surface, that is, the bottom of the groove (38) is
Make it a little larger than the width of 8). The container (18) 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 with the rail part (38) at the upper edge of the container side rail (24). Then, it is slidable by contacting the bottom side. As a result, the door (23) can be pulled out together with the container (18) from the inside of the main body (5).

At this time, the lateral displacement of the container side rail (24) and the main body side roller (28) is restricted within the width of the concave groove (38), so the container side rail (24) and the door (22) are slanted. It is prevented that the rollers (26) and (28) are smoothly slid on the body side rail (27) and the bottom of the rail portion (38).

FIG. 3 shows a perspective view excluding the container (18) with the door (23) fully pulled out, and FIG. 4 shows a side view of the rear portion of the container side rail (24) at that time. Horizontal piece (36) of the rail part (38) located slightly forward from the rear end of the container side rail (24).
A substantially triangular locking portion (41) having front and back inclined surfaces is formed so as to project downward. The rear end (38a) of the rail portion (38) ends before the rear end of the container side rail (24), and is further cut out at the upper part of the rear end of the container side rail (24). Further, there is provided a stop piece (42) which is further bent outward and is formed so as to be located behind the rail portion (38). Furthermore, this stop piece (42) and rail part (38)
A space (43) is formed between the rear ends (38a). The width of this space (43) is 20 mm in the embodiment, while the radius of the rollers (26), (28) is 11 mm (thus the diameter is 22 mm). Further, (44) is a support member for supporting the rear part of the container (18). The support member (44) has both ends of the rod crushed into a flat plate shape to form a fixed portion (44a), and the fixed portion (44a) is used as the roller (2).
It is fixed by tightening together with the shaft screw (26a) of 6).
The fixing portion (44a) extends upward and is bent backward, and the horizontal portion is fixed by the screw (45) and the shaft screw (26a), whereby the central portion of the support member (44) is fixed. The container (18) is supported in front of the roller (26).

Next, the operation will be described. When the inside of the door (23) is in contact with the refrigerator (1) and the opening is closed, the container (18) is stored in the refrigerator (1) as shown in FIG. From this state, the door (23) is opened by pulling it toward you, and eventually the main body side roller (28) comes into contact with the locking portion (41). In this state, the container (18) is substantially pulled out, and the opening is opened to the outside of the refrigerator so that articles can be delivered. Next, for example, when it is desired to remove the container (18) in order to clean the inside of the container (18), the door (23) can be pulled further forward, so that the locking portion (41) can get over the main body side roller (28) and the roller ( 28) eventually comes into contact with the stop piece (42), and the upper part thereof enters the space (43) as shown in FIG. At this time, the rear end (38a) of the rail (38) is
In the embodiment, the position in contact with 8) is about 36 ° from the horizontal centering on the shaft screw (28a). As a result, the container side rail (24) side surely matches the main body side roller (28) and does not come off. Further, since the lower end of the stop piece (42) moves relatively downward, the stop piece (42) is positioned in a range including at least the rear of the shaft screw (28a) even if the vertical dimension of the stop piece (42) is short. be able to. Therefore, when the container-side rail (24) is removed from the refrigerator (1), the distance for lifting the roller (28) upward in order to escape is short, and therefore the removal is easy.

If the width of the gap (43) is larger than the radius of the main body side roller (28) and smaller than the diameter, the intended purpose can be achieved, but it will surely stop when pulling out, and when it is pushed back. In order to make it easier for the end (38a) to get over the roller (28), the rear end (38a) is located within the range of 45 ° ± 10 ° from the horizontal centering on the shaft screw (28a) in the state as shown in FIG. It is desirable to have such dimensions.

In the state shown in FIG. 3 or 4, all the containers (18) go out of the refrigerator and can be removed. The above operation is the same for the door (22).

(G) Effect of the Invention According to the present invention, since the lower surface of the rail portion is placed on the main body side roller and the upper surface thereof supports the opening edge of the container, the portion supporting the opening edge of the container and the main body as in the conventional case. Since it is not necessary to vertically separate the part mounted on the side roller, the vertical dimension of the container side rail becomes smaller than before, and it is possible to suppress material waste of the container side rail and reduce material cost,
It is possible to set a small distance between the upper convex part of the two convex parts to which the main body side rail is attached and the lower end of the stop piece formed on the container side rail, and shorten the length of the main body side rail shaft. In addition, the width of the container can be increased to increase the volume of the container and the material cost of the main body side roller can be reduced. In addition, a gap larger than the radius of the body-side roller and smaller than the diameter is formed between the rear end of the rail portion and the stop piece so that the body-side roller can be inserted within this gap. The container side rail moves downward with respect to the main body side roller as much as the distance between the main body side roller and the main body side roller comes into contact with the stop piece with the main body side roller entering the gap, and the main body side roller and the container side rail. Can be reliably stopped to prevent further door pulling operations. At this time, the main body side roller is prevented from moving (rotating) in the front direction of the container side rail at the rear end of the rail portion, and is prevented from moving (rotating) in the rear direction by the stop piece. The gap can reliably prevent the container-side rail from moving forward and backward. In particular, since the container side rail moves downward with respect to the main body side roller, it is possible to reduce the vertical dimension of the stop piece by at least the distance moved downward, further reducing the material cost of the container side rail. Can be achieved.
