BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer type door of a refrigerator.

[0002]

2. Description of the Related Art A refrigerator of this type will be described with reference to FIGS. Reference numeral 1 is a refrigerator main body, 2 is a freezing room, and 3 is a refrigerating room.
Reference numeral 5 is a freezer compartment door, and 6 is a refrigeration compartment door, which is pivotally fixed to the refrigerator body 1 by an upper hinge 7, a middle hinge 8 and a lower hinge 9. A vegetable compartment 4 is partitioned from the refrigerating compartment 3 by a partition member 10 and a partition plate 11. Reference numeral 12 denotes a fixed rail having a U-shaped cross section, which is mounted on the inner surfaces of the left and right heat insulating walls of the refrigerator body 1. Numeral 13 is a fixed roller which is located near the front end of the fixed rail 12 and is rotatably fixed to the inner surfaces of the left and right heat insulating walls of the refrigerator body 1. Reference numeral 21 is a door that closes the front surface of the vegetable compartment 4 and is formed into a rectangular thin container shape, and further has an inward flange 21b formed on the entire circumference thereof.
c, the heat insulating material 21d is foamed and hardened inside, and the heat insulating material 21d is hidden by the door inner plate 21e.
Reference numeral 22 denotes a frame body, which is a movable rail member 2 in which an iron plate having a substantially U-shaped cross section is formed in an L shape and the movable roller 16 is axially fixed at one end.
2a, 22b, and a rod member 22c that connects the movable rail members 22a and 22b. The frame 22 having such a structure is fixed to the reinforcing iron plate 21c with the screw 23 with the door inner plate 21e interposed. Reference numeral 24 denotes a vegetable compartment container made of plastic which has an upper opening and is placed on the frame 22. The lower surface of the U-shaped flange of the movable rail members 22a and 22b of the frame body 22 slides on the fixed roller 13, and the movable roller 16 slides on the fixed rail 12 so that the door 21 and the vegetable compartment container 24 are interlocked. Then, it could be freely withdrawn. However, in the above-mentioned conventional technique, the cost of the reinforcing iron plate 21c, the frame 22 and the like is high, and the door inner plate 21e and the front wall of the vegetable compartment container 24 are double walls, which is expensive.
As a means for eliminating the high cost, a method of integrally forming the movable rail member with the vegetable compartment container and attaching the movable roller to the vegetable compartment container and then directly attaching the vegetable compartment container to the door can be considered. It has not been implemented for some reason.
For example, there is a case where a child who is short and out of reach gets out of the vegetable compartment and rides on the drawer door in an attempt to open the door of the freezer compartment. At this time, the distance between the door and the fixed roller is maximum, and the weight of the child becomes a force to push up the movable roller portion by the action of the lever with the fixed roller as a fulcrum. However, since the movable roller is restricted from moving up and down by the fixed rail, the weight of the child riding on the door is concentrated as a bending moment on the fixed roller, and the vegetable compartment container is damaged. It should be noted that, as an analogy to the present invention,

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problem that the vegetable compartment container is damaged when a child rides on it, and the movable rail member is formed integrally with the vegetable compartment container and is movable. By mounting the roller on the vegetable compartment container and then directly attaching the vegetable compartment container to the door, it is intended to eliminate the high cost of the prior art.

[0004]

According to the present invention, a fixed rail is provided on the refrigerator body side, a fixed roller is provided near the tip of the fixed rail, a vegetable compartment container having an upper surface opening on the door side, a movable rail member, and a movable rail portion seating material. In a drawer-type door of a refrigerator in which a movable roller is provided at a substantially rear end of the refrigerator, the movable roller slides on the fixed rail, and the movable rail member slides on the fixed roller, the movable roller is integrally movable with the vegetable compartment container. A rail member is formed, and an intermediate portion of a flexible member having movable rollers attached to both ends is attached to a rear wall of the vegetable compartment container.

[0005]

According to the above means, when the door is pulled out and an excessive force is applied to the upper surface of the door by a child or the like, the excessive force serves to deform the flexible member with the fixed roller as a fulcrum. It is possible to avoid stress concentration on the fixed roller in the conventional structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to FIGS. For 1 to 13, the same product, the same structure,
Since the operation is the same, the description is omitted.

Numeral 14 is a vegetable compartment container which is formed of plastic at the top opening and is horizontally formed outside the left and right walls 14a, a movable rail member 14d, a flange 14e formed on the outer periphery of the front wall 14b, and a rear wall 14c. A substantially inverted L-shaped support member 14f, reinforcing ribs 14g located at the lower ends of both ends of the support member 14f, and a screw boss 14h are integrally formed at the center of the upper portion of the support member 14f. Reference numeral 15 is a flexible member formed of an elastic body such as a round bar steel material, and fixed to both ends with screws (not shown), or by caulking (not shown) or the like, the movable roller 16 is rotatably axially fixed.

Reference numeral 17 denotes a metal fitting having an L-shaped cross section, which has a hole (not shown).
have. Reference numeral 18 is a vegetable compartment door that closes the front of the vegetable compartment, and is composed of a rectangular thin container-shaped door plate material 18a formed with an inwardly facing flange 18b and a heat insulating material 18c foamed and hardened inside. ing. Then, the flexible member 15 is provided between the rear wall 14c and the substantially inverted L-shaped support member 14f formed on the rear wall 14c of the vegetable compartment container 14,
The flexible member 15 is attached to the support member 1 by the L-shaped piece of the metal fitting 17.
The metal fitting 17 is pressed against the 4f side and the metal fitting 17 is tightened and fixed to the screw boss 14h by the screw 19. Thereafter, the terrange 14e formed on the outer periphery of the front wall of the vegetable compartment container is fixed to the flange 18b of the vegetable compartment door with a screw (not shown) or the like.

Above, the vegetable compartment door 18, the vegetable compartment container 14, the flexible member 15, and the movable roller 16 are integrally connected, and then the movable roller 16 is placed inside the fixed rail 12 and the movable rail member 14d is placed above the fixed roller 13. It becomes a door that can be pulled out by sliding. Next, the action of the movable rail member when an excessive force (for example, a child gets on) is applied to the upper surface of the vegetable compartment door with the vegetable compartment door pulled out will be described. The weights of the vegetable compartment door, the vegetable compartment container, etc., and the weight of the food stored in the vegetable compartment container shall be ignored. Vegetable room door 18
If the force applied to the upper surface of G is G, and the distance between the action point of G and the fixed roller 13 is 5 times the distance between the fixed roller 13 and the movable roller 16, the force of G is that of the lever with the fixed roller 13 as a fulcrum. According to the principle, the rear wall 14 of the vegetable compartment container 14
It acts on c as 5 G and as an upward force. At this time, the movable roller 16 is restricted in vertical movement by the fixed rail 12, but the rear wall 14 of the vegetable compartment container 14 is restricted.
Since the flexible member 15 is formed as a cantilever having a movable roller 16 at its tip between the flexible member 15 and c, the flexible member 1
5 bends and deforms as shown by the alternate long and short dash line in FIGS. That is, the rear wall 14c of the vegetable compartment container 14 rotates about the fixed roller 13 as a fulcrum to a force equilibrium point. As described above, the bending moment, which has been concentrated on the movable rail member 14d of the vegetable compartment container 14 located on the fixed roller 13 in the related art, can be relaxed, so that the vegetable container can be prevented from being damaged. The flexible deformation of the flexible member 15 is caused by the normal use condition, that is, by the weight of the drawer vegetable door and the weight of the food stored in the vegetable chamber container. Since it is a cantilever, it can be freely set by changing the material, sectional shape, and length from the fixed end to the tip of the free end of the flexible member 15. If the force of G is extremely large, the vegetable compartment door 18
It is also possible to prevent the vegetable compartment container 14 from being damaged by bringing the lower surface of the container into contact with the floor surface (shown by the one-dot chain line in FIG. 1). Still another method is to integrally form the flexible member 15 on the rear wall 14c of the vegetable compartment container 14.

[0010]

As described above, the flexible rail member having the movable rollers at both ends is fixed to the rear wall of the vegetable compartment container and the movable rail member is horizontally extended outside the left and right walls of the vegetable compartment container. After being integrally formed with plastic,
Since the vegetable compartment container is directly screwed to the flange of the door, the reinforcing iron plate, door inner plate, and frame of the prior art are not required, and the structure is simple, the resource is saved, and the cost is low.
