The door container 13 is attached to the engaging projection 18 of the door inner plate 15 by engaging the engaging portion 20. Here, in the door container 13, the pressing part 19 (point B in FIG. 5) from the position (point A in FIG. 5) which the engaging part 20 and the locking protrusion 18 contact | connects. )] To L2. Moreover, the position (point D in FIG. 5) which the engaging projection 18 and the engaging part 20 contact | connect from the upper part (point C in FIG. 5) of the protrusion part 16 on the door inner board 15 side. )] Is set to L3. In that case, L1 and L2 are provided so that it may become substantially the same dimension. Exactly L2> L3.

Assisting this coupling relationship is the shape of the locking projection 18 which has the above-mentioned relationship of D1 <D. That is, even when the dimensions of L2 and L3 substantially coincide, when the locking projections 18 have a relationship of D1 < D, the coupling relationship of the coupling portion 20 becomes possible. Moreover, it is preferable to comprise so that L2> L3 may be correct. Moreover, the pressing part 19 is provided over the full length of the height direction of the door container 13, and contacts the upper surface 16a of the protrusion part 16. As shown in FIG.

Reference numeral 21 is an upper portion of the door container 13 and is a flange provided to protrude outward in accordance with the projecting dimension of the engaging portion 20. When the flange 21 mounts the door container 13 to the protrusion 16, the flange 21 contacts the door inner plate 15 and between the outer side surface of the door container 13 and the inner side 16b of the protrusion 16.

In addition, the engaging portion 20 has a key shape (approximately L-shaped), and two surfaces contact the locking projections 18 when engaging the locking projections 18. By the above structure, the movement below and the front of the door container 13 is restrict | limited by the engagement relationship of the key-shaped engagement part 20 and the locking projection 18. As shown in FIG. In addition, the movement which the door container 13 tries to rotate to an up-down direction is regulated by combining the relationship of the press part 19 and the protrusion part 16, and the relationship of the engaging part 20 and the locking protrusion 18. As shown in FIG.

Next, the lock apparatus of the door container 13 is demonstrated using FIG. 6 thru | or FIG. 6 is a view showing a state in which the slide lock portion of the lock device protrudes in the lock direction. FIG. 7A is a diagram illustrating a state in which the slide lock portion of the lock device does not protrude in the lock direction. FIG. 7B is a view showing that the slide lock inclined surface touches the locking projection and slides. FIG. 8 is a view showing a state in which the cover of the lock device is removed in the state of FIG. 6.

The lock apparatus 22 shown in FIGS. 6-8 is a slide lock part located in the space which the operation part 23 attached to the outer side surface of the door container 13 shown in FIG. 4, and the flange 21 make. 24 is provided. Moreover, this operation part 23 and the slide lock part 24 are integrally provided. And the operation part 23 moves integrally using the coil spring 25, as shown also in FIG. That is, one end of the coil spring 25 is fixed to the door container 13 side, and the other end is fixed to the mounting part 23a of the operation part 23 (FIG. 8 state). And the lock apparatus 22 moves the inside of the recessed part 26 made in the outer side surface of the door container 13 to the front-back direction (left-right direction in FIG. 7). At this time, the rail is formed on the lock device 22 side and the rail groove is formed on the recess 26 side, and both of them can be smoothly moved left and right by the operation unit 23 of the lock device.

In the state of FIG. 6, the slide lock part 24 located in space is located in the position which approached the locking protrusion 18. As shown in FIG. This position is a position where a part of the slide lock portion 24 is in contact with or close to the bottom of the locking projection 18 when the door container 13 is attached to the door inner plate 15. This is a reduced state. And when the operation part 23 is moved to P4 direction like FIG.7 (a), it is set so that the slide lock part 24 may be in contact with or not close to the locking projection 18. As shown in FIG.

In the state where the coil spring 25 is extended, in other words, the lock device 22 is not displaced from the state of FIG. 6 to the state of FIG. 7A, the door container 13 is locked by the slide lock part 24. It becomes the structure which is caught by the projection 18 and does not come out from the door inner board 15. FIG. That is, when the locking projection 18 and the engaging portion 20 are coupled by the elastic force of the coil spring 25, the slide lock portion 24 is restricted to be located below the locking projection 18.

Therefore, when removing the door container 13 attached to the door inner board 15, if the operation part 23 of the lock apparatus 22 is moved to arrow P4 direction, the slide lock part 24 may be caught. ), The door container 13 is easily pulled upward. By setting it as such a structure, it is not necessary to make the engagement relationship of the engagement protrusion 18 and the engagement part 20 into the fitting state (press-in state) as before. Moreover, the protrusion 27 provided in the upper part of the slide lock part 24 shown in FIGS. 6-8 is a guide pin which regulates the movement of the slide lock part 24. As shown in FIG. Here, the slide lock portion 24 is restricted from moving in the direction of the arrow P3.

Reference numeral 28 is an inclined surface formed on the slide lock portion 24. By forming the inclined surface 28, the engaging portion 20 on the side of the door container 13 can be coupled to the locking projection 18 even without operating the operation portion 23. That is, when it does not have the inclined surface 28, the slide lock part 24 touches the latching protrusion 18, and the door container 13 cannot enter the door inner board 15 any more. By the way, the inclined surface 28 is formed in the slide lock part 24 as shown in FIG.7 (b), and when the door container 13 presses slightly strongly downward, the inclined surface 28 will catch | engage the projection 18. The slide lock part 24 slides out (slides) in the direction of arrow P4 of FIG. That is, when the inclined surface 28 is in contact with the upper portion of the locking projection 18, the slide lock portion 24 moves forward in response to the elastic force of the coil spring 25, and rides over the locking projection 18. . As a result, the resistance force of the coil spring 25 that is tensioning the slide lock portion 24 is overcome, and the coil spring 25 is extended to move the slide lock portion 24 in the direction of Fig. 6 to Fig. 7A. Displacement is to be coupled to the engaging projection 18 of the coupling portion 20.

Moreover, the cover 23C of the operation part 23 protrudes outward in the position of the coil spring 25, as shown in FIG. 4, and the upper and lower sides have 23d of recessed parts. That is, the cover part 23C which has a convex part is provided in the operation part 23 near the center, and the coil spring 25 is provided in the said convex part. As a result, the user's finger is likely to be spread across the recess 23d with the coil spring 25 interposed therebetween, and the user's finger sufficiently contacts the operation unit. Thereby, a user can operate the operation part 23 by lifting the door container 13, and the position of the door container 13 can be changed easily.

Next, FIG. 9: is a figure which shows the relationship between the rotation part R1 of the operation part 23 of the lock apparatus 22, and the refrigerating compartment door 2a. In FIG. 9, when the refrigerating compartment door 2a is opened and closed, the operation unit 23 of the lock device 22 provided on the opposite side of the hinge of the door container 13 enters the inside of the rotation trajectory R1 of the refrigerating compartment door 2a. . That is, when the rotational trajectory R2 of the operation part 23 accompanying the opening / closing operation of the refrigerating compartment door 2a is not located inside the rotational trajectory R1 of the refrigerating compartment door 3, the refrigerating compartment door 2a and the refrigerating compartment door 2b ), The dimension W should be as large as that dimension. In this way, it is not necessary to enlarge the gap dimension W between the refrigerating compartment door 2a and the refrigerating compartment door 2b by letting the rotational trajectory R2 of the operation part 23 enter the inside of the rotational trajectory R1. In addition, this is an example in the case of installing the rotating partition part 34 in the refrigerator compartment door 2a side. In the case where the rotary partition 34 is provided on the refrigerating compartment door 2b side, it is necessary to set the rotation trajectory R2 to the inside of the trajectory R3 passing through the end of the refrigerating compartment door 2a side of the rotary compartment 34.

Next, with reference to FIGS. 10-12, the Example of the lock apparatus 29 different from the lock apparatus 22 shown in FIG. 7 is demonstrated. FIG. 10: is a figure explaining the lock apparatus different from the lock apparatus shown in FIG. 11 is a diagram illustrating a state in which the lock device of FIG. 10 is not rotated. It is a figure which shows the state which rotated the lock apparatus of FIG.

Unlike the lock device 29 described with reference to FIGS. 6 to 8, the rotation lock part 30 is configured to rotate around the support point 31. As a result, the door container 13 in contact with or close to the locking projection 18 can be prevented from falling out of the door inner plate 15.

This lock apparatus 29 has an operation part 32 and the rotation lock part 30 linked with the said operation part 32. As shown in FIG. The engaging portion 20 has a key shape (approximately L-shaped) as in the above-described configuration. The support point 31 is provided on the outer side surface of the door container 13, and is located in front of the door container (left side in FIGS. 11 and 12) rather than the engaging portion 20. FIG. Here, the front means the direction toward the inside of the refrigerator compartment 2 from the door inner plate 15 in the state which closed the refrigerator compartment door 2a. In addition, in the state of FIG. 11 in which the locking projection 18 engages with the engaging portion 20, the support point 31 is located in front of the locking projection 18 (left side in FIG. 11). In addition, when the door container 13 is attached, it is provided so that the locking projection 18 may be located in the rotation trace of the rotation lock part 30. As shown in FIG. Thereby, even if the force of the lifting direction to the door container 13 is applied, since the rotation lock part 30 abuts on the lower part of the locking projection 18, it can prevent that the door container 13 falls out.

As shown in FIGS. 11 and 12, when the operation unit 32 is not operated to resist the torsion spring 33, the rotational lock unit 30 contacts with or close to the locking projection 18. There is no relationship drop. That is, when the door container 13 is attached to the door inner plate 15, the rotation lock part 30, the coupling part 20, the torsion spring 33, and the locking protrusion so that the door container 13 may not be easily pulled out. The operation of the door container 13 is regulated by the relationship of (18). On the other hand, when the user operates the operation unit 32 as described above, the rotation lock unit 30 rotates in response to the torsion spring 33. In doing so, the locking projection 18 and the rotation lock portion 30 fall as shown in FIG. In this state, the user can also easily remove the door container 13 from the door inner plate 15 by lifting the door container 13 upward.

In other words, the lock apparatus 29 of the door container 13 is in the state of FIG. 11 before mounting to the door inner board 15, and when mounting this to the door inner board 15, the position of the rotation lock part 30 is changed. As shown in FIG. 12, the locking projection 18 is passed in the state where the operation unit 32 is displaced so as to be in the state of FIG. 11. Moreover, using the inclined surface 30a of the rotation lock part 30, the inclined surface 30a of the rotation lock part 30 contacts the locking projection 18, and presses the door container 13 to the locking projection 18 side. The islands door container 13 can be attached to the door inner plate 15.

By setting it as such a structure, even when the external force of the direction pushing up against the door container 13 is applied, the door container 13 can be prevented from falling out from the door inner board 15. As shown in FIG.

Moreover, by operating the operation part 23 provided in the door container 13 by the user, the slide lock part 24 which contacts or comes close to the engaging protrusion 18 can be easily released, and the The mounting position can be easily changed.

In addition, when the door container 13 is attached to the door inner plate 15, the slide lock portion 24 can be simply attached to the locking projection 18 by simply pushing the door container 13 downward. The user can easily and reliably mount the door container 13 to the door inner plate 15.
