An embodiment in which the present invention is applied to a refrigerator will be described below with reference to the drawings.

First, in Figure 1, 1 is the refrigerator body,
Inside this, a freezer compartment 2, a refrigerator compartment 3, and a storage compartment 4 for refrigerating vegetables, fruits, etc. are formed in order from the top so that the front side of each compartment is open.
Reference numerals 5 and 6 denote doors for the freezer compartment and the refrigerator compartment, respectively, which are provided at the front openings of the freezer compartment 2 and the refrigerator compartment 3 so as to be rotatable to open and close. Reference numeral 7 designates a substantially rectangular door that opens and closes the front opening of the storage chamber 4 by moving back and forth, as will be described later. A storage container 8 is housed in the storage chamber 4, and is held between movable rails 9, which will be described later, to which a door 7 is attached to the front end. In FIGS. 2 and 3, reference numeral 10 denotes a fixed rail attached to the left and right inner walls of the storage chamber 4. This rail is made of metal plate material and is formed into a substantially U-shape, and the bottom surface is open at the top. The letter-shaped concave portion 11 is formed by bending, and its inner surface serves as a guide surface 11a. 12 and 1
Reference numeral 3 denotes a rear stopper and a front stopper which are attached to the outer surface of the grooved portion 11 with a gap between them. Reference numeral 14 denotes an intermediate rail, which is formed by bending a metal plate into a substantially U-shape. 15 is a plurality of first rollers rotatably pivoted near the lower end of the intermediate rail 14;
Reference numeral 16 denotes a second roller rotatably mounted near the rear/upper end of the intermediate rail 14; 17 is a movable roller provided at the upper end of the intermediate rail 14 so as to be movable back and forth; A guide member 19 with a rotating shaft 18 attached to the upper part of the intermediate rail 14
It is configured to be able to move in the longitudinal direction within the long groove 20 of. This intermediate rail 14 has a first roller 15 that rolls on the guide surface 11a of the fixed rail 10 to move back and forth within the concave portion 11, and the lower surface of this intermediate rail 14 has the front stopper 13 and the a first stop portion 2 constituting a first stopper means;
1 is provided, and when this first stop portion 21 hits the front stopper 13, the intermediate rail 14 is at the maximum extended position A. The movable rail 9 is formed into a substantially U-shape by bending both ends of a vertical surface 9a of a metal plate at substantially right angles, and furthermore, the movable rail 9 has a horizontally oriented bent portion 9b at the lower end thereof. The shape is formed by bending a concave portion 22 which is substantially U-shaped and is open downward at a predetermined distance from the vertical surface 9a, and the inner surface of the concave portion 22 serves as a guide surface 22a. Both falling portions 23 of this grooved portion 22,
23 is formed wider than the width dimension of the first roller 15, and the movable rail 9 has a guide surface 22a such that both falling portions 23, 23 of the grooved portion 22 sandwich the first roller 15. first roller 1
5 is placed on the upper edge of the concave portion 22, and the concave portion 22 is placed between the first roller 15 and the movable roller 17, and the first roller 15 rolls on the guide surface 22a of the concave portion 22. By moving, the movable rail 9 is guided by the intermediate rail 14 and moves back and forth. Reference numeral 24 denotes a protrusion that protrudes downward in a chevron shape from the concave portion 22 of the movable rail 9, which contacts the first roller 15 when the intermediate rail 14 is pulled out to the maximum pull-out position A, and This is the restriction means B that restricts movement of the object further forward than this point. When the intermediate rail 14 is pulled out to the maximum pull-out position A and the door 7 is pulled out until the protrusion 24 of the movable rail 9 contacts the first roller 15, the rear end of the storage container 8 is placed in the storage chamber. 4, and this state is defined as the stored goods removal position C.
25 and 26 are second blocking parts and blocking parts provided on the lower surface of the movable rail 9 and the intermediate rail 14, respectively, so that a predetermined distance D exists when the protrusion 24 contacts the first roller 15. , these second blocking portions 25 and blocking portions 26 constitute a second stopper means, and the movable rail 9 pushes the protrusion 24 into the first stopper means.
When pulled out forward past the roller 15 of the second
The blocking part 25 hits the blocking part 26 to determine the maximum pull-out position of the movable rail 9, and this state is the container attachment/detachment position E, and the rear end of the storage container 8 is lower than the front part of the storage chamber 4. It is located a distance D ahead. 27 is an elastic pawl attached to the front end of the movable rail 9; 28 is a chevron-shaped engagement protrusion formed on the front end of the fixed rail 10 that corresponds to the elastic pawl 27 when the door 7 is closed; A first sloped portion 30 with a gentle slope angle is formed on the front side, and a horizontal first guide surface 31 is formed continuously from the first sloped portion 30. Reference numeral 32 designates a second sloped portion with a steep slope formed from the top portion 29 toward the storage chamber 4;
A second guide surface 33 is formed continuously from the inclined portion 32 of the guide surface 32 . The horizontal distance of the first inclined part 30 is formed to be sufficiently longer than the horizontal distance of the second inclined part 32, and the height difference from the top part 29 to the first guide surface 31 is the same as that of the second inclined part 32. It is set to be larger than the height difference up to the guide surface 32. Therefore, elastic claw 2
7 slides on the first guide surface 31 and the first sloped part 30 when the door 7 is closed, crosses the top part 29 and engages with the second sloped part 33, and is elastic. The structure is such that when the claw 27 matches the top 29 of the engagement projection 28, there is a slight gap between the door 7 and the front surface of the storage chamber 4.

Note that the gap between the lower surface of the first guide surface 31 and the upper end of the intermediate rail 14 is formed to be extremely small.

Next, the operation of the above configuration will be explained.

Pull the door 7 forward and move the elastic claw 27 to the second inclined part 3
3 and over the top 29. When the door 7 is pulled out, the movable rail 9 connected to the door 7 rotates the first roller 15 of the intermediate rail 14 that is in contact with the grooved portion 22 of the movable rail 9, and the rotation of the first roller 15 causes the intermediate rail to move. 14 is fixed rail 1
0 on the guide surface 11a of the concave portion 11.
Therefore, the moving distance between the movable rail 9 and the fixed rail 10 is twice the moving distance between the movable rail 9 and the intermediate rail 14. Then, the front stopper 13 of the fixed rail 10 contacts the first stop 21 of the intermediate rail 14, and the first roller 15 contacts the convex portion 24 of the movable rail 9, preventing the movable rail 9 from moving forward. The door 7 is placed in the stored goods removal position C (see FIG. 7). Thus, the intermediate rail 14 is supported between the fixed rails 10 by the first roller 15 and the second roller 16, and the movable rail 9 is supported by the intermediate rail 14 by the first roller 15 and the movable roller 17. The storage container 8 is supported in a protruding state from the fixed rail 10 and the intermediate rail 14, respectively, and is fully pulled out to the front end of the storage chamber 4. When removing the storage container 8, when the door 7 is further pulled forward, the convex portion 24 of the movable rail 9 moves over the first roller 15, and connects the blocking portion 26 and the second collision. The stop portion 25 is brought into contact with the door 7, and the door 7 is placed in the container attachment/detachment position E (see FIG. 8). Here, since the storage container 8 is located ahead of the storage chamber 4 by a predetermined distance D, the storage container 8 can be easily attached to and removed from the movable rail 9. Next, the closed door state will be explained. Normally, when loading and unloading stored goods, the door 7 is opened to the stored goods retrieval position C, but if the door 7 is pushed in the direction of the main body 1 from this stored goods retrieval position C, the inertia of the door 7 moves the movable rail 9 and the middle rail 1
4 move to the storage main body 1 side. Then, when the elastic claw 27 of the movable rail 9 passes over the top 29 of the engagement convex portion 28 of the fixed rail 10, the elastic claw 27 uses its elastic force to move the door 7 along the second inclined portion 32 into the storage body. 1 side to ensure door closing. Furthermore, if the elastic claw 27 does not go over the top 29 of the engaging protrusion 28 and stops before it, that is, when the door 7 is in a half-open state (see Fig. 9), the elastic claw 27 will move to the first position due to its elastic force. The movable rail 9 is moved backward by sliding along the inclined part 30, and the distance between the door 7 and the front part of the storage room 4 is expanded.

According to the above embodiment, when the door 7 is opened, the intermediate rail 14 can be projected from the fixed rail 10 and supported, and the movable rail 9 can be further projected from the intermediate rail 14 and supported, so that the storage container 8 can be Since the storage container 8 can be positioned at the front of the storage chamber 4 to facilitate loading and unloading of stored items, and the storage container 8 can be positioned sufficiently forward at the container attachment/detachment position E, the door 7 can be removed as in the conventional case. The storage container 8 can be easily removed without it.

In particular, in the above embodiment, the intermediate rail 14
Since the vertical distance between the fixed rail 10 and the fixed rail 10 is extremely small, even if a heavy object or the like accidentally falls onto the door 7 while the door 7 is open, and the main body 1 is tilted ( (See Figure 10) The cabinet body 1 is supported by the door 7, movable rail 9, and intermediate rail 14.
can be prevented from falling over.

[Effect of idea]

As is clear from the above description, the present invention provides a first stopper means on the fixed rail and the movable rail so as to stop the intermediate rail at the maximum extended position, so that the intermediate rail is at the maximum extended position. A regulating means is provided for regulating the movable rail from the normal withdrawing position of the intermediate rail to position the storage container at the stored goods retrieval position in a state in which the intermediate rail is pulled out, and the door moves further forward beyond the regulation by the regulating means. When the movable rail is further pulled out by being moved, the movable rail is stopped at a maximum pullout position with respect to the intermediate rail, and the storage container is located at a container attachment/detachment position where the storage container can be attached to and detached from the movable rail. By providing the second stopper means on the intermediate rail and the movable rail so as to allow the storage container to move in and out of the storage container, the storage container can be easily attached and removed.
