That is, guide rails 2 extending in the front-rear direction are provided on the left and right side wall portions (only the left side wall is shown in the figure) of the storage chamber 1 such as a freezer compartment, and above the front portions of these guide rails 2. The support roller 3 is provided at the site in a state of protruding into the storage chamber 1.

  A support member 5 is attached to the back surface of the door 4 that opens and closes the front opening of the storage chamber 1. The support member 5 has a substantially U-shape in which the rear end portions of a pair of support plate portions 5a extending along the guide rail 2 are connected by a connecting portion 5b, and the upper edge of each support plate portion 5a. A projecting portion 5c projecting outward is integrally provided at the portion, and a guide roller 6 is provided at the rear portion of each support plate portion 5a so as to project outward. The storage container 7 is detachably supported by the support member 5.

  The support member 5 is guided in the front-rear direction along with the opening and closing of the door 4 by inserting each guide roller 6 into each guide rail 2 and hooking each overhanging portion 5 c to each support roller 3 to be supported. The storage container 7 is inserted into and removed from the storage chamber 1 by causing the support member 5 to support the storage container 7.

  However, in the above-described conventional configuration, since the guide rollers 3 attached to the left and right side walls of the storage chamber 1 protrude into the storage chamber 1, the width of the storage container 7 supported by the support member 5 in the left-right direction. There is a drawback that the size cannot be increased, and consequently the volume of the storage container 7 cannot be increased.

  This invention is made | formed in view of the said situation, The objective is providing the storage which can enlarge the width dimension of the left-right direction of a storage container as much as possible, and can enlarge the capacity | capacitance of a storage container as much as possible by extension. It is in.

  In order to achieve the above-mentioned object, the invention of claim 1 includes a storage chamber having an opening on the front surface, a guide portion provided on the left and right side walls of the storage chamber so as to extend in the front-rear direction, and a front-rear direction. A door that opens and closes the front opening of the storage chamber by the movement of the storage chamber, a support member that is provided on the back surface of the door and has support plate portions extending along the guide portions on the left and right sides, and a left and right side of the support member.

A fixture having a support roller, a stopper provided at a rear portion of the support member, abutting against the support roller or the fixture and restricting the forward movement of the support member, and supported by the support member In state, A storage container that is taken in and out of the storage chamber as the door is opened and closed, and the fixture is fitted into a recess provided at the front edge of the bottom of the storage chamber via a nail fitting. The front part of the fixture is characterized in that it is configured to abut on the concave part.

  According to the above means, since the support roller for receiving and supporting the support plate portion of the support member is provided on the bottom side of the storage chamber, compared to the support roller provided on the side wall of the storage chamber, It becomes possible to enlarge the width dimension of the storage container in the left-right direction as much as possible. In addition, since the fixture having the support roller is fitted into the recess provided at the bottom of the storage chamber, the amount of support roller protruding into the storage chamber can be suppressed, and the height of the storage container can be reduced. The size can be increased as much as possible, and this also makes it possible to increase the volume of the storage container as much as possible. Furthermore, since a support roller or a fixture is used to restrict the forward movement of the support member, there is an advantage that it is not necessary to provide a dedicated stopper or the like on the storage chamber side.

  Hereinafter, an embodiment in which the present invention is applied to a refrigerator will be described with reference to FIGS. First, in FIG. 6 showing the entire refrigerator as a storage, inside the refrigerator main body 11, the refrigerator compartment 12, the ice making room 13, the specification switching room 14, the freezer compartment 15, and the vegetable compartment 16 are arranged in order from the top. Each chamber 12-16 is opened and closed by independent doors 17-21. Of the doors 17 to 21, the door 17 of the refrigerator compartment 12 is a rotary type that opens forward with the right side as a fulcrum, and the other doors 18 to 21 are of a drawer type that pulls forward.

  In this case, although not shown in detail, the chambers 12, 13, 15, 16 except for the specification switching chamber 14 among the chambers 12 to 16 are provided in the inner box 22 (see FIG. 5) of the main body 11. Although it forms integrally, about the specification switching chamber 14, the storage chamber formation box 23 formed by injection molding is attached to the inner box 22 separately from the inner box 22, and the inside of this storage chamber formation box 23 is specified. The switching chamber 14 is formed.

  A damper device 24 that controls the amount of cool air supplied into the specification switching chamber 14 is provided at the rear of the specification switching chamber 14. In this case, the specification switching chamber 14 can switch the cooling temperature in a wide range. By switching, the specification switching chamber 14 can be one of a freezing chamber, a partial freezing chamber, a chilled chamber, a refrigerated chamber, and a vegetable chamber. It can be selected and used. In addition, although not shown, an automatic ice making device is disposed in the ice making chamber 13.

  The ice making chamber 13 and the freezing chamber 15 below the ice making chamber 13 may be in the same temperature range. As shown in FIG. 1, a partition cover 25 made of a member different from the inner box 22 of the main body 11 is provided in front of the ice making chamber 13 and the specification switching chamber 14. The partition cover 25 is integrally provided with a frame portion 26 corresponding to the peripheral edge portion of the ice making chamber 13 and a frame portion 27 corresponding to the peripheral edge portion of the specification switching chamber 14. The lower part 26a of the frame part 26 corresponding to the peripheral part of the ice making room 13 partitions the ice making room 13 and the freezing room 15 at the front part.

  Accordingly, in this case, the front opening 13a of the ice making chamber 13 is formed by the frame portion 26, and the front opening 14a of the specification switching chamber 14 is formed by the frame portion 27. These front opening portions 13a and 14a correspond to each other. The doors 18 and 19 are opened and closed.

  Now, guide rails 30 constituting guide portions extending in the front-rear direction are provided at the lower portions of the left and right side wall portions of the specification switching chamber 14. As shown in FIG. 2, the guide rail 30 has a U-shaped cross section. Support rollers 31 are attached to the left and right sides of the lower side portion 27a of the frame portion 27 constituting the front edge portion of the bottom portion of the specification switching chamber 14. As shown in FIG. 3, the support rollers 31 are partially inserted into the groove portion 34 of the fixture 33 attached to the frame portion 27 by inserting the pin 32 inserted therethrough from above. In the state embedded in 27, it is rotatably supported by the fixture 33.

  On the other hand, a support member 35 is attached to the back surface of the door 19 that opens and closes the front opening 14 a of the specification switching chamber 14. The support member 35 has a pair of support plate portions 36 extending along the guide rails 30 on the left and right sides, and a connecting portion 37 that connects the rear end portions of the pair of support plate portions 36 as a whole. It has a letter shape. Each support plate portion 36 includes a side plate portion 36a and a horizontal plate portion 36b projecting inward from the lower end portion of the side plate portion 36a, and the cross-section is substantially L-shaped. A guide roller 38 is attached to the rear portion 36a so as to protrude outward.

  As shown in FIGS. 2 and 5, the storage member 39 is detachably supported by the support member 35 such that the bottom of the storage container 39 is received by the horizontal plate portion 36 b of the support plate portion 36. It has become.

  Thus, the support member 35 inserts the guide rollers 38 into the guide rails 30, and receives and supports the horizontal plate portions 36 b of the support plate portions 36 on the support rollers 31, thereby opening and closing the door 19. The storage container 39 is guided in the front-rear direction, and the storage container 39 is inserted into and removed from the specification switching chamber 14 by the support member 35 supporting the storage container 39.

  A stopper 40 that protrudes downward is provided at the rear part of each horizontal plate portion 36b. When the support member 35 is fully pulled forward, the stopper 40 contacts the support roller 31 (see FIG. 4). Therefore, the stopper 40 and the support roller 31 cooperate to restrict the support member 35 and thus the storage container 39 from moving further forward.

  Although not illustrated, the ice making chamber 13 side also employs a drawer structure similar to the specification switching chamber 14 side, and as a storage container supported by a support member (not shown) as the door 18 opens and closes. This ice storage container is configured to be taken in and out of the ice making chamber 13.

  According to the embodiment described above, in the specification switching chamber 14, the support roller 31 that receives and supports the support plate portion 36 of the support member 35 provided on the back surface of the door 18 is provided on the bottom side of the specification switching chamber 14. As a result, the support roller 31 does not protrude laterally with respect to the specification switching chamber 14. Therefore, in the conventional configuration, it is possible to make the width dimension in the left-right direction of the storage container 39 as large as possible as compared with the support roller 3 provided on the side wall of the storage chamber 1. The volume can be increased as much as possible.

  Further, each support roller 31 is provided so as to be partially embedded in the lower side portion 27a of the frame portion 27 of the partition cover 25 that constitutes the bottom portion of the specification switching chamber 14, so that the upward protrusion amount And the height dimension of the storage container 39 can be increased as much as possible, and this also makes it possible to increase the volume of the storage container 39 as much as possible.

  Furthermore, each support roller 31 is configured to be attached to a partition cover 25 which is a separate member from the inner box 22 of the main body 11, so that a portion to which the support roller 31 is attached can be manufactured relatively easily, and the support roller. 31 can be easily attached. In particular, in the present embodiment, the support roller 31 is mounted by inserting the pin 32 inserted through the support roller 31 into the groove 34 of the fixture 33 from above, so that the mounting can be further simplified, and if necessary. Can be easily removed. Since the shaft of the support roller 31 may be a simple rod-shaped pin 32, it is easy to manufacture and the cost can be reduced.

  Further, since the stopper 40 provided on the support plate portion 36 of the support member 35 is applied to the support roller 31 so as to restrict the forward movement of the support member 35, the forward movement of the support member 35 is prevented. In order to regulate, there is an advantage that it is not necessary to provide a dedicated stopper on the specification switching chamber 14 side.

  FIG. 7 shows a modified example of the stopper 41. The stopper 41 protrudes largely downward from the stopper 40 on the horizontal plate portion 36b of the support plate portion 36 of the support member 35, and when the support member 35 is fully pulled forward, the frame portion 27 In this case, the support member 35 is restricted from moving forward by abutting against the upper end portion of the lower side portion 27a, in this case, the upper end portion of the fixture 33.

  FIG. 8 shows a modification of the support roller 42. The support roller 42 has a configuration in which a convex portion 43 is provided on the entire outer periphery. In such a configuration, the horizontal plate portion 36b in the support member 35 comes into contact with the outer peripheral surface of the convex portion 43, and the contact area between the horizontal plate portion 36b and the support roller 42 is reduced. As a result, the noise generated at the support roller 42 is reduced.

The present invention is not limited to the above-described embodiments, and can be modified or expanded as follows.
For example, the width of the storage container 39 in the left-right direction can be further increased by deeply embedding the guide rail 30 constituting the guide portion in the side wall portion of the specification switching chamber 14.

  The drawer configuration described above can also be applied to the freezer compartment 15 and the vegetable compartment 16. Furthermore, the present invention is not limited to a household refrigerator, and can be applied to various storages.
