Description

  Embodiments of the present invention relate to a refrigerator.

  In general, some refrigerators are provided with a drawer-type container in a vegetable room or a freezer room. In this case, the drawer-type container is realized by, for example, a slide rail that expands and contracts in the front-rear direction as the door moves in the front-rear direction. Such a slide rail generally has a ball retainer type guide roller. In this case, since the ball-retainer type guide roller has a plurality of balls, the structure thereof is complicated, and the work such as removal is difficult. Furthermore, since a slide rail having a ball retainer type guide roller moves while a plurality of balls are simultaneously in contact with the rail, each member constituting the rail is required to have a relatively high accuracy. For this reason, the conventional configuration has such a situation that manufacturability and workability are not good.

  Next, assembly of the fixing member 40, the intermediate member 50, and the container side member 60 will be described. First, the user attaches the intermediate member 50 to the fixing member 40. Specifically, the user first inserts the distal end portion of the intermediate member 50 into the fixing member 40 from the rear end portion of the fixing member 40 with the locking block 44 removed from the fixing member 40. At this time, as shown in FIGS. 6 and 7, the second piece 404 of the fixing member 40 enters the second groove 531 of the second auxiliary member 53 provided in the intermediate member 50. As a result, the second piece 404 of the fixing member 40 is inserted into the second groove 531 of the second auxiliary member 53 provided in the intermediate member 50.

  Thereafter, the user inserts the second pulley 51 of the intermediate member 50 between the second rail portion 43 of the fixing member 40, that is, the second rail upper surface portion 402 and the second rail lower surface portion 431. The member 50 is moved to the front side of the fixing member 40. At this time, as shown in FIG. 6, the first rail portion 501 of the intermediate member 50 is positioned above the first pulley 41 of the fixing member 40. Further, as shown in FIG. 7, the first piece 504 of the intermediate member 50 is inserted into the first groove 421 of the first auxiliary member 42 provided in the fixing member 40. As a result, the first piece 504 of the intermediate member 50 is inserted into the first groove 421 of the first auxiliary member 42 provided on the fixing member 40. Then, the locking block 44 is attached to the fixing member 40.

  In this state, the first rail portion 501 of the intermediate member 50 is supported by the first pulley 41 provided at the front portion of the fixing member 40. In addition, the second rail lower surface portion 431 of the second rail portion 43 of the fixing member 40 supports the second pulley 51 provided at the rear portion of the intermediate member 50. Accordingly, the intermediate member 50 is configured to be movable in the front-rear direction with respect to the fixed member 40. In this case, the second piece portion 404 of the fixing member 40 slides in the front-rear direction along the second groove portion 531 of the second auxiliary member 53 provided in the intermediate member 50. Further, the first piece 504 of the intermediate member 50 slides in the front-rear direction along the first groove 421 of the first auxiliary member 42 provided in the fixing member 40.

  As shown in FIGS. 3 and 4, the first pulley 41 and the second pulley 51, and the third pulley 52 and the fourth pulley 61 are arranged so as to overlap each other. Moreover, as shown in FIG. 6, the 1st pulley 41 and the 3rd pulley 52 are arrange | positioned so that it may overlap up and down.

  Next, the user attaches the container side member 60 to the intermediate member 50. Specifically, first, the user moves the fourth pulley 61 of the container side member 60 in the front-rear direction of the intermediate member 50 and the front end of the third pulley 52 and the fourth rail upper surface portion 502 provided on the intermediate member 50. It is located between the part 507. In this state, the locking portion 602 of the container side member 60 is located in front of the third pulley 52.

  Then, the user tilts the front end portion of the container-side member 60 slightly upward, for example, and avoids the locking between the locking portion 602 and the third pulley 52, and moves the fourth pulley 61 to the top surface of the fourth rail. The container side member 60 is moved rearward along the fourth rail portion 56 while entering between the portion 502 and the fourth rail lower surface portion 503. At this time, as shown in FIG. 7, the third piece 505 of the intermediate member 50 enters the third groove 621 of the third auxiliary member 62 provided on the container side member 60.

  Thereafter, the container side member 60 is further moved to the rear, and thereby the container side member 60 is attached to the intermediate member 50. In this state, the third rail portion 601 of the container side member 60 is positioned above the fixing member 40 and the intermediate member 50 as shown in FIG. The third rail portion 601 is supported by a third pulley 52 provided at the front portion of the intermediate member 50. The fourth rail lower surface portion 503 among the fourth rail portions 56 provided in the intermediate member 50 supports the fourth pulley 61 provided in the rear portion of the container side member 60. Accordingly, the container side member 60 is configured to be movable in the front-rear direction with respect to the intermediate member 50.

  In this state, the third groove portion 621 of the third auxiliary member 62 provided in the container side member 60 includes the third piece portion 505 of the intermediate member 50. In this case, the third groove portion 621 of the third auxiliary member 62 provided on the container side member 60 slides relatively in the front-rear direction along the third piece portion 505 of the intermediate member 50. The fourth pulley 61 of the container side member 60 is located between the fourth rail portion 56 of the intermediate member 50, that is, between the fourth rail upper surface portion 502 and the fourth rail lower surface portion 503. Therefore, the container side member 60 is restricted from moving upward. And as shown also in FIG. 7, the 2nd pulley 51 of the intermediate member 50 and the 4th pulley 61 of the container side member 60 are arrange | positioned so that it may overlap with an up-down direction.

  When the door 25 is pulled in a state where the door 25 is attached to the container side member 60, the container side member 60 moves forward. In this case, the distance between the third pulley 52 and the fourth pulley 61 decreases as the container-side member 60 moves forward. However, regardless of the position of the container-side member 60, the container-side member 60 has two locations: a third pulley 52 at the front of the intermediate member 50 and a fourth pulley 61 at the rear of the container-side member 60. It is supported.

  Here, when the fourth pulley 61 of the container-side member 60 is located behind the intermediate member 50, the fourth pulley 61 includes the fourth rail lower surface portion 503 among the fourth rail portions 56 of the intermediate member 50. It is supported by. On the other hand, when the container side member 60 is pulled out and the fourth pulley 61 is positioned in front of the intermediate member 50, that is, when the third pulley 52 and the fourth pulley 61 are close to each other, When the weight in the storage container 161 is relatively heavy, the front end portion of the container side member 60 is rotated downward and the rear end portion is rotated upward with the third pulley 52 as a fulcrum with respect to the container side member 60. Force to act. In this case, the fourth pulley 61 of the container side member 60 is supported by the fourth rail upper surface portion 502 among the fourth rail portions 56 of the intermediate member 50. Thereby, even if the weight in the storage container 161 is comparatively heavy and the force of the front lower direction acts with respect to the container side member 60, the container side member 60 does not remove | deviate from the intermediate member 50. .

  Thereafter, when the container side member 60 is further pulled forward and the locking portion 602 of the container side member 60 is locked to the third pulley 52 of the intermediate member 50, the forward movement of the container side member 60 is the intermediate member. 50. Thereby, the intermediate member 50 is pulled out together with the container side member 60. Then, when the intermediate member 50 and the container side member 60 move further forward, the front side retaining portion 54 provided on the intermediate member 50 is engaged with the engaging claw portion 403 of the fixing member 40. Thereby, the intermediate member 50 and the container side member 60 are restricted from moving forward from the locking claw portion 403.

  In this case, the relationship between the intermediate member 50 and the fixing member 40 is the same as the relationship between the container side member 60 and the intermediate member 50. That is, as the intermediate member 50 moves forward, the distance between the first pulley 41 and the second pulley 51 decreases. However, regardless of the position of the intermediate member 50, the intermediate member 50 is supported at two locations, the first pulley 41 at the front of the fixing member 40 and the second pulley 51 at the rear of the intermediate member 50. Yes.

  Here, when the second pulley 51 of the intermediate member 50 is positioned behind the fixing member 40, the second pulley 51 is placed on the second rail lower surface portion 431 among the second rail portions 43 of the fixing member 40. It is supported. On the other hand, when the intermediate member 50 is pulled out and the second pulley 51 is positioned in front of the fixing member 40, that is, when the first pulley 41 and the second pulley 51 are close to each other, further storage is performed. When the weight in the container 161 is relatively large, the intermediate member 50 has a force that rotates the front end portion of the intermediate member 50 downward and the rear end portion upward with the first pulley 41 as a fulcrum. Works. In this case, the second pulley 51 of the intermediate member 50 is supported by the second rail upper surface portion 402 of the second rail portion 43 of the fixing member 40. Thereby, even if the weight in the storage container 161 is comparatively heavy and the force of the front lower direction acts on the intermediate member 50, the intermediate member 50 does not remove | deviate from the fixing member 40. FIG.

  The user can remove the door 25 and the storage container 161 from the refrigerator 10 by a procedure reverse to the case where the container side member 60 is attached to the intermediate member 50. That is, the user pulls out the door 25, and after the locking portion 602 of the container side member 60 is locked to the third pulley 52 of the intermediate member 50, the user lifts the door 25 slightly upward, etc. Tilt the front end upward. Then, when the door 25 is further pulled out with the front end portion of the container side member 60 tilted upward, the locking portion 602 gets over the third pulley 52. Thereby, the container side member 60 becomes movable further forward.

  Thereafter, the door 25 is further pulled out, and the container side member 60 is moved forward until the fourth pulley 61 is positioned in front of the front end portion 507 of the fourth rail upper surface portion 502. Then, the fourth rail upper surface portion 502 of the intermediate member 50 does not exist above the fourth pulley 61. Therefore, the container-side member 60 can be moved upward as the fourth pulley 61 is locked to the fourth rail upper surface portion 502 of the intermediate member 50. Therefore, the container side member 60 can be detached from the intermediate member 50. Thereby, the user can remove the door 25 and the storage container 161 from the refrigerator 10.

  In this configuration, the first pulley 41 functions as a first support portion, the second pulley 51 functions as a second support portion, the third pulley 52 functions as a third support portion, and the fourth pulley 61 functions as a fourth support portion. To do. In this case, each of the support portions 41, 51, 52, 61 may be a low-friction sliding member that does not rotate but has excellent slidability instead of a pulley.

  According to this, the slide rail 30 used for the drawer-type storage container 161 can have a simple structure as compared with, for example, a ball retainer type, and as a result, improvement in manufacturability and assemblability is achieved.

  The parts 40, 50, 60 of the slide rail 30 are not required to have much precision as compared with, for example, a ball retainer type. Therefore, even when each component 40, 50, 60 is painted, the influence of the dimensional change due to the coating on the operation of the slide rail 30 is small. Therefore, the coating of each component 40, 50, 60 becomes easy, and as a result, the design of the appearance of the slide rail 30 can be improved.

  The first pulley 41 and the second pulley 51, and the third pulley 52 and the fourth pulley 61 are arranged so as to overlap each other. Further, the first pulley 41 and the third pulley 52, and the second pulley 51 and the fourth pulley 61 are arranged so as to overlap each other. According to this, the slide rail 30 as a whole can be configured to be thin in the left-right direction. As a result, the storage container 161 attached to the slide rail 30 can have a large capacity.

  The fixing member 40, the intermediate member 50, and the container side member 60 are each made of metal. The fixing member 40 is provided with a resinous first auxiliary member 42. The first groove portion 421 of the first auxiliary member 42 includes the first piece portion 504 of the intermediate member 50. The intermediate member 50 is provided with a resinous second auxiliary member 53. The second groove portion 531 of the second auxiliary member 53 includes the second piece portion 404 of the fixing member 40. Thereby, the intermediate member 50 can move to the front-back direction stably, without removing from the fixed member 40 to the inner side of the warehouse.

  Similarly, the container side member 60 is provided with a resinous third auxiliary member 62. The third groove portion 621 of the third auxiliary member 62 includes the third piece portion 505 of the intermediate member 50. Thereby, the container side member 60 can move to the front-back direction stably, without removing from the intermediate | middle member 50 to the warehouse inner side.

  Further, since the fixing member 40 and the first auxiliary member 42, and the intermediate member 50 and the second auxiliary member 53 are configured separately, the metal fixing member 40 and the intermediate member 50 are directly connected to each other. There is no need to include it. Similarly, since the container side member 60 and the third auxiliary member 62 are configured separately, it is not necessary for the metal container side member 60 and the intermediate member 50 to directly hold each other. Therefore, the fixing member 40, the intermediate member 50, and the container side member 60 which are metal increase the freedom degree of the shape. As a result, the slide rail 30 as a whole can be reduced in size and thickness.

  Further, when the door 25 is pulled out, the container side member 60 can be detached from the intermediate member 50 in a state where the locking portion 602 has moved over the third pulley 52 of the intermediate member 50 and moved forward of the third pulley 52. . According to this, even after the fixing member 40 and the intermediate member 50 are attached to the inner wall 101, the container side member 60 to which the door 25 is attached can be easily attached to and detached from the intermediate member 50. . As a result, the assembly and workability can be further improved.

  The first rail portion 501 that receives the first pulley 41 provided at the front portion of the fixing member 40 is configured by a metal intermediate member 50. The third rail portion 601 that receives the third pulley 52 provided in the front portion of the intermediate member 50 is configured by a metal container-side member 60. Therefore, the first rail part 501 and the third rail part 601 can be made relatively durable. According to this, even when a large load is applied to the first rail portion 501 and the third rail portion 601, the sliding operation can be performed stably even when the accommodation weight in the storage container 161 is heavy.

  Moreover, the 1st pulley 41 and the 2nd pulley 51 are provided in the substantially same height position in the up-down direction. A second pulley 51 is provided behind the first pulley 41. The third pulley 52 and the fourth pulley 61 are provided at substantially the same height in the vertical direction. A fourth pulley 61 is provided behind the third pulley 52. According to this, the slide rail 30 can reduce the thickness in the left-right direction while suppressing the height dimension in the up-down direction as a whole.

  A third rail portion 601 that receives the third pulley 52 provided at the front portion of the intermediate member 50 is provided at the uppermost portion of the container side member 60. The third rail portion 601 is located above the intermediate member 50 and the fixing member 40. According to this, when the door 25 is pulled out and the storage container 161 is removed, the fixing member 40 and the intermediate member 50 do not interfere with the removal of the container side member 60. Therefore, the container side member 60 can be easily detached from the intermediate member 50 together with the door 25 and the storage container 161.

  As mentioned above, according to the refrigerator of embodiment, the slide rail used for a drawer-type storage container can be made into a simple structure compared with the thing of a ball retainer type, for example. As a result, improvement in manufacturability and assemblability is achieved. Furthermore, it becomes easy to paint each part of the slide rail, and the design of the appearance of the slide rail can be improved.
