Description

Storage

The present invention relates to a storage provided with a storage chamber for storing a drawer container.

Some conventional storages have a self-closing structure in which plate-like springs are provided on one or both sides of the drawer container and the drawer container is pulled into the storage chamber by the force of the spring. However, in the self-closing structure of the drawer container using a spring, when the drawer container is pulled in, the drawer container is positioned by hitting a stopper provided in a peripheral part. At this time, when the drawer container is pulled strongly, a loud contact sound is generated.

Also, as a self-closing structure of the drawer container, there are also storages provided with rollers and rails in the drawer container and the heat insulating box. In such a self-closing structure, a downward bending shape is applied to the rail, and the drawer container is closed by its own weight. However, in such a structure, the roller of the drawer container vigorously rolls on the inclined portion on the rail of the heat insulation box, so that the drawer container hits the stopper at the time of positioning and a contact sound is generated.

Therefore, in order to alleviate the contact sound, a storage is known in which a gasket is provided on a door interlocked with a drawer container (see, for example, Patent Document 1). The storage of Patent Document 1 has a pair of frames that support a door with a gasket and a drawer container, and the guide on the side of the heat insulation box has a rear end of a movable range in which a roller provided on the frame rolls. It is bent downward. When the door is closed, the roller rolls down the last part of the guide, so that the drawer container is accommodated in the storage chamber by its own weight.

The operation state of the drawer container 32 will be described with reference to FIGS. 5 to 8, some of the detailed reference numerals are omitted to avoid complication of the drawings.

When the drawer door 31 and the drawer container 32 are set again in the freezer compartment 30 from the removed state as shown in FIG. 3, the moving roller 5 and the rail part 6 are replaced with the guide rail part 8 and the upper rail as shown in FIG. 9 is inserted between. The moving roller 5 moves horizontally while passing over the guide horizontal portion 81. During this time, the movement of the drawer container 32 in the front-rear direction is not affected by its own weight. Therefore, if the user does not apply force to the drawer door 31, the drawer container 32 does not move. That is, the drawer container 32 moves according to the force applied to the drawer door 31 by the user. In the state of FIG. 5, the fixed roller 7 is in contact with the horizontal portion 61.

FIG. 6 shows a state in which the drawer container 32 is drawn into the freezer compartment 30. When the moving roller 5 is on the guide inclined portion 88 as shown in FIG. 6, the moving roller 5 rolls down toward the guide convex portion 8 b due to the inclination of the guide inclined portion 88. That is, the drawer container 32 is drawn into the freezer compartment 30 by its own weight. While the moving roller 5 passes over the guide horizontal portion 82, the drawer container 32 moves rearward with little deceleration unless the user applies any force. In the state of FIG. 6, the fixed roller 7 is in contact with the inclined portion 66.

As shown in FIG. 7, when the moving roller 5 comes into contact with the guide convex portion 8b and gets over the guide convex portion 8b, the moving roller 5 has an R shape extending over the guide horizontal portion 82 of the guide convex portion 8b, and the guide convex portion. Deceleration is caused by the shape of the protrusions extending on the guide support portion 8a of the portion 8b. That is, the speed at which the drawer container 32 is drawn into the freezer compartment 30 is decelerated when the moving roller 5 passes over the guide protrusion 8b. Then, after moving over the guide convex portion 8b, the moving roller 5 is positioned by being fitted to the guide support portion 8a. In the state of FIG. 7, the fixed roller 7 is in contact with the convex portion 6b. Moreover, in the state of FIG. 8, the fixed roller 7 is fitted in the holding part 6a.

That is, in the state shown in FIG. 5, when a backward force is applied to the drawer door 31, the drawer container 32 is pulled into the freezer compartment 30 by its own weight, and the drawer door 31 closes the front of the freezer compartment 30. As described above, the storage 10 employs a self-closing structure that draws the drawer container 32 into the freezer compartment 30 and closes the drawer door 31 by using the weight of the object to be stored in the drawer container 32. In the state shown in FIG. 8, when the drawer container 32 is pulled out from the freezer compartment 30, the user may pull the drawer door 31 forward so that the moving roller 5 gets over the guide convex portion 8b.

Further, in the first embodiment, the guide base portion 8c and the base portion 6c have corresponding shapes. That is, the guide horizontal portion 81 has a length in the front-rear direction, and the horizontal portion 62 is equal to. The guide inclined portion 88 is equal in length and inclination angle to the inclined portion 66. The guide horizontal portion 82 has a length in the front-rear direction equal to that of the horizontal portion 61. Accordingly, as shown in FIGS. 5 to 8, the drawer container 32 is kept horizontal with the moving roller 5 in contact with the upper surface of the guide base portion 8c and the fixed roller 7 in contact with the lower surface of the base portion 6c. It can be stably moved in the front-rear direction.

Furthermore, in the first embodiment, the guide support portion 8a and the holding portion 6a, the guide convex portion 8b and the convex portion 6b, and the guide concave portion 8d and the concave portion 6d have the same shape. Therefore, the operation until the movable roller 5 is fitted to the guide support portion 8a, the fixed roller 7 is fitted to the holding portion 6a, and the drawer container 32 is positioned can be stably performed.

As described above, in the storage 10 according to the first embodiment, the guide support portion 8a into which the moving roller 5 is fitted from above is provided behind the guide inclined portion 88 of the guide rail portion 8. Therefore, the impact due to positioning when the drawer container 32 is stored can be alleviated without using an impact absorbing member such as a gasket. Therefore, according to the store | warehouse | chamber 10, generation | occurrence | production of the contact sound at the time of accommodation of the drawer | drawing-out container 32 can be suppressed, and the self-closing structure excellent in durability can be implement | achieved. In addition, since the contact sound when the drawer container 32 is stored can be suppressed, a high-class feeling can be enhanced. Moreover, the rail part 6 is provided in the front-end part, and has the holding | maintenance part 6a in which the fixed roller 7 fits from the bottom. Therefore, since the drawer container 32 can be supported on both the front side and the rear side, it can be stored in the freezer compartment 30 in a stable state.

Furthermore, the guide rail portion 8 is connected to the front end portion of the guide support portion 8a and has a guide convex portion 8b protruding upward. Accordingly, since the moving roller 5 can be decelerated before the moving roller 5 is fitted to the guide support portion 8a, an impact when the moving roller 5 is fitted to the guide support portion 8a can be weakened. Similarly, the rail portion 6 has a convex portion 6b that is connected to the rear end portion of the holding portion 6a and protrudes downward. Therefore, since the fixed roller 7 can be decelerated before the fixed roller 7 is fitted to the holding portion 6a, an impact when the fixed roller 7 is fitted to the holding portion 6a can be weakened.

Further, the rail portion 6 has a recess 6 d connected to the moving roller 5. Therefore, when the moving roller 5 is fitted into the guide support portion 8a from above, the guide convex portion 8b is fitted into the concave portion 6d from below. Therefore, it is possible to prevent the moving roller 5 from rolling to the rear of the guide support portion 8a and to stably position the drawer container 32. Further, the guide rail portion 8 has a guide recess 8 d connected to the fixed roller 7. Therefore, when the fixed roller 7 is fitted into the holding portion 6a from below, the convex portion 6b is fitted into the guide concave portion 8d from below, so that the drawer container 32 can be positioned more stably.

In addition, the guide base 8c is provided between the fixed roller 7 and the guide inclined portion 88, and has a guide horizontal portion 81 having a constant upper surface height. Therefore, the state where the drawer container 32 is pulled out as shown in FIG. 5 can be maintained. Further, the main body 11 is provided with an upper rail 9 on the inner side surface 13a above the guide rail portion 8. Therefore, even when the arrangement balance of the objects to be stored in the drawer container 32 is poor, or when a vertical force is applied to the drawer door 31, the upward movement of the moving roller 5 and the rail portion 6 can be limited. it can. Therefore, the drawer door 31 and the drawer container 32 can be stably supported.

That is, the storage 10 draws the drawer container 32 into the freezer compartment 30 by the self-closing structure as described above. Even when the user applies a relatively strong force to the drawer door 31 in the rear, the drawer container 32 depends on the shape of the rail portion 6 and the guide rail portion 8 and the arrangement of the moving roller 5 and the fixed roller 7. It is possible to absorb an impact during storage. Therefore, contact between the drawer container 32 and peripheral components can be prevented.

Embodiment 2. FIG.

In the storage 10 of the second embodiment, the drawer door 31 is provided with a gasket 50 that absorbs an impact on at least one of an upper end portion and a lower end portion on the drawer container 32 side, that is, the rear side surface. In FIG. 9, the case where the gasket 50 is provided in both the upper end part and lower end part in the back side surface of the drawer door 31 is illustrated. When the drawer door 31 is closed, the gasket 50 at the upper end contacts the front end surface of the partition member 40, and the gasket 50 at the lower end contacts the front end surface of the bottom wall 11 a of the main body 11. Thereby, the impact when the drawer container 32 is positioned is further alleviated.

As described above, in the storage 10 according to the second embodiment, the gasket 50 is attached to the rear side surface of the drawer door 31. Therefore, when the drawer door 31 is closed by the self-closing structure of the drawer container 32, the impact is absorbed by the gasket 50, so that the contact between the drawer container 32 and peripheral parts can be avoided. Furthermore, since the storage according to the second embodiment has the same self-closing structure as the storage according to the first embodiment, the burden on the gasket 50 is reduced as compared with the conventional storage. Therefore, since the deterioration rate of the gasket 50 becomes slow, it can be used for a longer period of time than before.
