Function and Effect of the Invention

<Invention of Claim 1> The tray is supported so as to be able to be taken in and out by receiving both side edges thereof at the tips of the inclined support plates of both rails. Since the tray is received in a line contact state, the sliding resistance is suppressed and the tray can be smoothly taken in and out. When moisture adheres to the support plate of the rail, the moisture flows down along the inclination of the support plate and is discharged from the opening at the base of the substrate to the rear side. As water is prevented from accumulating on the rails,
Freezing between the support plate and the tray is prevented, so that the tray can be taken out smoothly. Also, since water does not collect on the rails,
There is an effect that it is possible to prevent water from spilling and hitting the storage.

<Invention of Claim 2> The water flowing down to the opening along the inclination of the support plate is discharged to the back side of the substrate through the drainage guide plate. The moisture can be more reliably discharged to the back side of the substrate, and the water adhering to the lower surface side of the support plate can be discharged to the back side of the substrate by transmitting the water drainage guide plate. <Invention of claim 3> By bending the leading edge of the support plate downward, the torsional rigidity of the support plate is enhanced, the shape is maintained well, and the smooth insertion and removal of the tray is ensured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
A description will be given based on FIG. In FIG.
Is a refrigerator main body formed by a heat insulating box body, in which a storage room 2 is formed, and a tray 3 on which storage items are placed is placed on a rail 5 from an entrance (not shown) provided on the front surface.
It is put in and out along, and is designed to be stored in multiple stages. The tray 3 is formed in a planar rectangular shallow dish shape.

Next, the rail 5 according to the present embodiment will be described. The rail 5 is formed by press-forming a stainless steel plate. As shown in FIG. 2, the rail 5 has an elongated shape in the depth direction of the storage chamber 2 as a whole, and The support plate 7 is bent inward at a predetermined acute angle θ (see FIG. 1).
Are formed. Therefore, when the substrate 6 takes a vertical posture, the support plate 7 takes an inclined posture having a downward slope from the front end toward the base end side.

At the base of the substrate 6, the substrate 6
The four openings 8 shown in the figure are formed at intervals in the longitudinal direction by cutting and raising, and the cut and raised portions constitute the same surface as the inclined support plate 7 so that the rear surface is formed. Side, which forms a drainer guide plate 9. The opening area of the opening 8 is set to such an extent that a predetermined bending rigidity can be secured at a bent portion in accordance with the material of the plate material, the overall shape, and the like.

The front edge of the support plate 7 is further bent obliquely downward to form a mountain shape, and the top of the mountain forms a support portion 10 of the tray 3. By providing the bent portion 10a in this manner, the torsional rigidity of the support plate 7 is increased, and the support plate 7 is prevented from being distorted. Further, at both ends in the length direction of the substrate 6, there are provided extending pieces extending upward, and the extending pieces are formed in a shape which is bent to the rear side in the middle and then extends upward again. , So that the insert 1
1 is formed.

On the other hand, in the storage room 2, two front and rear shelf receiving columns 13 are attached to left and right wall surfaces 1a sandwiching the entrance. As shown in FIG. 3, the shelf receiving column 13 is formed by press-forming an elongated metal plate and forming a convex surface 14 at a central portion in the width direction.
The left and right side edges are mounting portions 16, and a plurality of mounting holes 15 on the convex surface 14, into which the insertion piece 11 of the rail 5 can be inserted and hooked, are formed vertically. It is formed at a predetermined pitch in the direction. Such shelf receiving columns 13 are erected on the entrance and exit sides of the left and right wall surfaces 1a, respectively, and are fixed by fixing the mounting portions 16 with screws 17 or the like.

This embodiment has the above structure,
Subsequently, the operation will be described. First, the rail 5 is the shelf support 13
Attached to. The pair of rails 5 are inserted with the support plates 7 facing inward, and the insertion pieces 11 at both ends are inserted obliquely upward into the mounting holes 15 of the corresponding front and rear shelf receiving columns 13, and then the rails 5 are lowered. The bent portion 11a of the insertion piece 11 is attached to the mounting hole 1 while the substrate 6 is in contact with the convex surface 14.
5, and the tip of the insertion piece 11 is hooked on the back surface of the upper edge of the mounting hole 15 so that the insertion piece 11 is attached in a retaining state. The pair of left and right rails 5 are mounted at the same height and in a facing position with the support plate 7 facing inward, and a plurality of rails 5 are provided at arbitrary heights as shown in FIG. Then, the tray 3 on which the stored matter is placed is supported so as to be able to be taken in and out over the support plates 7 of the pair of left and right rails 5.

In this case, the left and right side edges of the tray 3 are received by the support portion 10 which is the top of the tip of the support plate 7, but as described above, the support plate 7 has a tip with a chevron shape. Since the torsional rigidity is increased by bending, the support portion 10 is accurately linearly arranged without being distorted, and the tray 3 comes into line contact with the support portion 10, so that the sliding resistance is suppressed to a small value. Can be put in and out smoothly.

In addition, when water drops on the support plate 7 of the rail 5 or when the tray 3 is put into the tray 3 and water adheres to the tray 3 and the water adheres to the support plate 7, the water is removed from the support plate 7. It flows down along the slope to reach the openings 8 at the base of the substrate 6, flows down along the drainage guide plate 9 provided in each opening 8, and is discharged to the back side of the rail 5. Also, if the upper surface or the lower surface of the support plate 7 is frozen and melts, the upper surface side also travels along the upper surface of the drainage guide plate 9 from the opening 8 in the same manner as described above, and the lower surface side also has the lower surface , And is dropped and discharged from the tip.

As described above, according to the present embodiment,
A number of advantages are obtained, including: Since water is prevented from accumulating on the support plate 7 of the rail 5, icing between the supporting plate 7 and the tray 3 is prevented. The tray 3 is limited to a small area between the tray 3 and the tray 3, so that the tray 3 is prevented from freezing and hindering removal. In order to more reliably prevent the accumulation of water between the support portion 10 of the support plate 7 and the tray 3 due to surface tension and the occurrence of icing there, the support portion 10 has a sharper shape. do it.

Further, all the water discharged from the rail 5 is discharged to the rear side of the rail 5 through the drainage guide plate 9, so that the water drains on the lower rail 5 or is placed on the lower tray 3. It doesn't hang on the placed storage.
Since water does not accumulate on the rail 5 as described above, when the tray 3 is taken in and out, the water does not spill and hang on the stored items, which is sanitary. There is no hang over.

The tray 3 is received in a line contact state by the support portion 10 of the support plate 7, that is, since the sliding resistance is suppressed because the contact area is small, a heavy stock is placed on the tray 3. Even in this case, it can be smoothly put in and out. Furthermore, when cool air is circulated and supplied along the wall surface 1a of the storage room 2, the opening 8 is formed in the substrate 6 of the rail 5, so that the rail 5 is prevented from becoming a flow resistance. In addition, smooth circulation of cold air can be expected.
