In FIG. 1, a storage body 1 of a commercial refrigerator as a storage installed in a kitchen such as a restaurant.
Is a heat-insulating box having an opening on one side and has a storage chamber 2 inside. A front door 3, which is a heat insulating door, closes the opening of the heat insulating box. The front doors 3 are of a double door type and are provided vertically and horizontally and are rotatably attached to the storage body 1 by upper and lower hinge devices 4 and 5, respectively. A compressor 6, a condenser 7, an electrical equipment box 8 and a control box 9 are arranged on the upper surface of the storage main body 1.

In FIG. 2, the upper hinge device 4 for rotatably supporting the front door 3 has a general structure,
Cylindrical hinge shaft 11 and this hinge shaft 1
1 comprises a cylindrical shaft receiver 13 having a circular hole 12 into which 1 is inserted. The hinge shaft 11 is fixed to the storage body 1 via a bracket 16. on the other hand,
The shaft receiver 13 made of synthetic resin is embedded in the upper surface of the front door 3.

In FIGS. 3 and 4, the lower hinge device 5 that rotatably supports the front door 3 is composed of a prismatic hinge shaft 21 and a prismatic shaft receiver 23 that receives the hinge shaft 21. ing. The hinge shaft 21 is fixed to the storage body 1 via a bracket 26. On the other hand, the shaft receiver 23 made of synthetic resin is embedded in the lower surface of the front door 3, and comprises a collar 27 and a rotor 28 rotatably supported by the collar. The rotor 28 is composed of a columnar portion 29 and a collar portion 30, and the collar portion 30 is integrally formed at a lower end portion which is one end portion of the columnar portion 29. A notch 31 having a substantially rectangular cross section is formed in the rotor 28 in parallel with the axial direction, and the notch 31 has a cross section slightly larger than the cross section of the hinge shaft 21.
Can be fitted into the notch 31.

On the other hand, the collar 27 is formed with a circular hole portion 33 for supporting the rotor 28 in a rotatable manner, and an elongated groove portion 34 is formed in a substantially L shape so as to be continuous with the circular hole portion 33. ing. As shown in FIG. 5A, the groove 34 is a groove 3 for lateral movement substantially parallel to the lateral direction of the front door 3.
4a and a groove 34b for initial movement, which is formed by bending the end of the groove 34a at a substantially right angle. The groove portion 34b for initial movement is arranged substantially parallel to the depth direction of the front door 3. Further, the groove portion 34 for lateral movement
The corners of a and the groove 34b for initial movement are rounded, and the hinge shaft 21 inserted in the groove 34 is
Is configured to move smoothly.

The front door 3 is attached to the storage main body 1 by the upper and lower hinge devices 4 and 5 constructed as described above. The front door 3 closes the opening of the storage main body 1 and the storage. It is movable between a fully open position in which the opening of the main body 1 is largely opened. Then, as described above, the upper hinge device 4 rotatably supports the front door 3. On the other hand, the lower hinge device 5 operates as shown in FIG. When the front door 3 is in the closed position,
As shown in FIG. 5A, the hinge shaft 21 fixed to the storage body 1 is inserted into the groove portion 34 b for initial movement of the collar 27. When rotating the front door 3 to the fully open position, first, the lower side of the front door 3 is moved to the position shown in FIG.
Pull it toward you as indicated by the arrow in (a). Then, the hinge shaft 21 moves in the groove 34b for initial movement,
As shown in FIG. 5B, it is located at a corner portion that is a connecting portion between the groove portion 34a for lateral movement and the groove portion 34b for initial movement. At the time of this initial movement, the lower portion of the front door 3 moves toward the front side and also rotates a little. Although it is described that the hinge shaft 21 is moving in the groove 34,
Actually, the groove portion 34 is fixed to the hinge shaft 2
Moved to 1.

Next, the lower side of the front door 3 is moved to the lateral side as shown by the arrow in FIG. 5 (b). Then, the hinge shaft 21 moves in the groove 34a for lateral movement, and
After the state shown in FIG. 5C, as shown in FIG. 5D, the rotor 28 is fitted into the notch 31. When the lower hinge device 5 operates in this manner, the upper hinge device 4 hardly operates, and the upper part of the front door 3 rotates only slightly with respect to the hinge shaft 11. Is. Further, since the hinge shaft 21 has a prismatic shape, it slightly rotates while moving in the groove 34, but does not rotate largely. That is, the width of the groove portion 34 is formed to be substantially the same as the width of the hinge shaft 21 (strictly speaking, slightly larger), and the hinge shaft 21 can be largely rotated while being inserted into the groove portion 34. There is no.

Furthermore, when the front door 3 is pulled to the front side,
As shown in FIG. 5D, the collar 27 rotates with respect to the rotor 28 that receives the hinge shaft 21. That is, the lower portion of the front door 3 that is integrally formed with the collar 27 rotates with respect to the hinge shaft 21. At the same time, the upper part of the front door 3 can also rotate with respect to the hinge shaft 11 and can also rotate to the fully open position.

Since the lower hinge device 5 operates in this way, the front door 3 is in a substantially upright state as shown in FIG. 7A in the closed position, that is, the lower surface of the front door 3 is substantially horizontal. However, when the front door 3 is rotated, as shown in FIG.
As shown in (b), it is inclined so that the side far from the hinge devices 4 and 5 faces upward. The two-dot chain line L indicates the hinge shaft 11 of the upper hinge device 4 and the lower hinge device 5
A substantially vertical line connecting the hinge shaft 21 of FIG. In the state shown in FIG. 7B, the front door 3
The front door 3 is about to rotate counterclockwise due to its own weight, and the lower part of the front door 3 is about to move to the right side in the figure. By the way, when the front door 3 is rotated from the fully opened position toward the closed position and is almost closed, the notch 31 of the rotor 28 and the groove 34 for lateral movement of the collar 27.
matches a. Then, FIG. 5 (c) and FIG. 5 (d)
In the above, since the lower portion of the front door 3 is about to move to the right side as described above, the hinge shaft 21 does not move to the rotor 2.
It is possible to naturally shift from the notch 31 of 8 to the groove 34a for lateral movement. Then, when the front door 3 is pushed toward the storage body 1, the hinge shaft 21 moves along the groove 34 of the collar 27, and the front door 3 can be brought to the closed position shown in FIG. 5A.

As described above, in the embodiment, the front door 3
When rotating from the closed position to the fully open position, the lower part of the first first moves a little while moving to the front side, then laterally moves,
Then, it makes a large turn. By this first movement toward the front side and minute rotation, the end portion (left end portion in FIG. 5) of the front door 3 on the side far from the lower hinge device 5 is a distance substantially equivalent to the thickness of the front door 3. Only the front side is displaced. Therefore, the lower portion of the front door 3 that opens and closes is on the front side of the adjacent front door 3, and does not abut the side surface of the adjacent front door 3 when moving laterally, and the front side of the adjacent front door 3 It can be partially overlapped. By the way, when the front door 3 does not first move to the front side but moves laterally, the laterally moving front door 3 comes into contact with the side surface of the adjacent front door 3,
Lateral movement is hindered. Therefore, when there is the adjacent front door 3, it is necessary to move to the front side first. If the front doors 3 adjacent to each other do not exist, it is not necessary to move the front door 3 to the front side first, and it is possible to move the door first laterally.

Further, since the front door 3 is laterally moved in the middle of the rotation or at the beginning of the rotation, the stored items in the storage chamber 2, that is, the storage is shaken by the earthquake. Even if the front door 3 is hit from the inside of the refrigerator, the impact does not cause the front door 3 to be fully opened. Therefore, the stored items in the storage are less likely to jump out, and it is less necessary to clean up the stored products that have jumped out of the storage into the storage again after the earthquake has subsided.

Next, the second embodiment of the storage according to the present invention
Will be described with reference to FIG. FIG. 8 is an exploded perspective view of the lower hinge device according to the second embodiment. In the description of the second embodiment, constituent elements corresponding to the constituent elements of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In the first embodiment, the hinge shaft 2
1 is attached to the storage body 1 via the bracket 26, but in the second embodiment, the hinge shaft 2
1 is attached to the lower surface of the front door 3. On the other hand, the shaft receiver 23 is the storage main body 1 in the second embodiment.
It is provided directly on the bracket 41 which is attached with screws. The groove 34 and the circular hole 33 of the shaft receiver 23 are formed in a metal bracket 41, and the rotor 28 is rotatably provided in the circular hole 33. As described above, the arrangement position of the hinge shaft 21 is different between the first form and the second form, but regarding the operation, the second form is also substantially the same as the first form.

The embodiment of the present invention has been described above in detail.
The present invention is not limited to the above embodiment,
Within the gist of the present invention described in the claims,
Various changes can be made. Modification examples of the present invention are exemplified below. (1) In the embodiment, the hinge shaft 11 of the upper hinge device 4 is attached to the storage body 1 via the bracket 16, but it is also possible to attach the hinge shaft 11 to the front door 3 side. . In that case, the shaft receiver 13 is provided on the bracket 16 side.

(2) In the embodiment, the hinge device including the prismatic hinge shaft 21, the collar 27 and the rotor 28 is used only under the door.
It can be used both above and below the door, or only above the door. (3) In the embodiment, a pair of doors are arranged on the left and right sides to form a double door type, but in a left-right direction, a single-opening type storage having only one door is provided. The present invention can be adopted.

(4) In the embodiment, the shaft receiver 13 is formed separately from the front door 3, but the shaft receiver may be directly formed on the door. For example, it is possible to construct by forming a circular hole in the top plate of the door. (5) The groove 34a for lateral movement need only be arranged substantially parallel to the lateral direction of the front door 3, and does not necessarily have to be perfectly parallel, and may be slightly inclined. Similarly, the groove portion 34b for initial movement does not necessarily need to be completely parallel to the depth direction of the front door 3 and may be slightly inclined.

[0024]

According to the present invention, since the door of the storage is laterally moved when the door is rotated from the closed position or while the door is being rotated from the closed position to the fully opened position, the door is stored in the storage. Even if the stored items are shaken by an earthquake and hit the door from the inside of the refrigerator, the impact does not cause the door to fully open. That is, although the stored item pushes the door toward the front side, almost no force is generated to move the door laterally. Therefore, the door rarely opens, and the stored items in the refrigerator are prevented from popping out. As a result, it is not necessary to clean up the stored materials that have jumped out of the storage room again after the earthquake has subsided.

Further, the hinge device includes a hinge shaft,
The hinge shaft has a prism shape, and the hinge shaft has a prism shape, and the shaft holder includes a collar and a rotor rotatably supported by the collar. A notch is formed in the rotor to receive the hinge shaft, and the collar has a circular hole for rotatably supporting the rotor, and a groove formed continuously from the circular hole. Then
In addition, the groove extends substantially parallel to the lateral direction of the door. Therefore, when the door is rotated from the state where the hinge shaft is located at the end of the groove, the door needs to move laterally once, and even if the stored item pushes the door toward the front side, the door is not moved. It does not rotate. As a result, even if an earthquake occurs, the number of doors that rotate and open is reduced.

Further, the upper hinge device comprises a cylindrical hinge shaft and a shaft receiver having a circular hole for receiving the hinge shaft, while the lower hinge device has the prismatic hinge shaft. And the shaft receiver for receiving the hinge shaft. In this case, when the door is opened, the lower side of the door moves laterally and then rotates. Therefore, when the door in the closed position pivots to the fully open position, the door tilts. On the contrary, when the door is rotated from the fully open position to the closed position, when the door is returned from the tilted state to the closed position at the end of the rotation, the hinge shaft causes the notch portion of the rotor. It is possible to smoothly transition from the groove to the groove.
