[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to a storage part drawer structure in which the storage part is constructed as a drawer type.

[0002]

[Prior art]

 In many cases, refrigerators use hinged door type doors, but there are also cases in which the storage part has a drawer type structure and the back part is effectively used. Especially for commercial refrigerators, the tendency is strong. When the storage unit is configured as a drawer, the drawers are put in and taken out with the relatively heavy refrigerated items being put in, so special measures are required to smoothly put the drawers in and out. In addition, when the drawer is pulled out, most of it protrudes to the front of the refrigerator to form a cantilever structure, so that the supporting portion also needs to have appropriate strength. A dual structure rail has been proposed as a drawer rail that meets such requirements. The rail of this structure is basically composed of beam-shaped rails with a U-shaped cross section facing each other, and multiple balls are interposed between the flanges of both, but the drawer is pulled to the outermost position. In this case, the strength is high in the vertical direction, but there is a large amount of rattling in the horizontal direction, which causes a problem in durability. In addition, the above-mentioned double structure rail has a problem that the manufacturing cost is high due to the complicated structure and it is difficult to remove the drawer from the refrigerator body.

An integral rail as shown in FIG. 7 has been proposed as an alternative to the above-mentioned double structure rail. To further explain this, a pair of fixed rails 3 are provided on the inner surface of the refrigerator main body 1, and two rolling support rollers 5 are fixed to the outside of the inlet side end thereof. The movable rail 9 having a pair of rollers 7 rolling on both sides of the lower flange of the fixed rail 3 at the rear end is pulled out through an inlet defined between the lower frame 1a and the middle frame 1b of the main body 1. Although it is pushed or pushed in, the door 6 is fixed to the entrance side thereof, and the pair of movable rails 9 and the door 6 are in a drawer shape as a whole. Then, the refrigerated item is put in the storage case 8 placed on the refrigerated item. When the door 6 and the movable rail 9 are pulled out, the stopper 9a abuts on the rail support plate 1c and is stopped to prevent the door 6 and the movable rail 9 from popping out. The rolling support roller 5 and the roller 7 momentally support the weight of the refrigerated object in the storage case 8 when it is pulled out to the outermost position.

[0004]

[Problems to be solved by the device]

 As described above, the own weight and the weight of the refrigerated article when the door or the like is pulled out to the outermost position are moment-supported. That is, the door or the like tries to rotate counterclockwise with the rolling support roller at the outermost position as a fulcrum, but the roller at the innermost side hits the fixed rail and is stopped. The distance between the rollers tends to be long in order to keep the load of these rollers at an allowable value, and as a result of the restriction on the amount of withdrawal, it is inconvenient to take out the refrigerated items and the storage case. In detail, the storage case cannot be removed unless it is tilted as shown in the figure. Therefore, an object of the present invention is to provide a high-strength storage compartment withdrawing structure that has a large maximum withdrawal amount and can be easily attached to and detached from the refrigerator body so that refrigerated items and storage cases can be easily taken out. It is what

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a pair of horizontal fixed rails provided on the inner surface of the storage part of the refrigerator so as to face each other, and a guide roller which is guided by the fixed rails to roll. And a pair of movable rails extending in parallel with each other, a drawer door fixed to one end of the pair of movable rails to open and close the entrance of the storage unit, and the storage unit adjacent to the inlet side end of the horizontal fixed rail. In a refrigerator having a rolling bearing roller that is rotatably provided on the inner surface of the unit and that bears the movable rail while rotating, a rail that is located below the rolling bearing roller and is installed at the entrance of the storage unit. It is characterized in that it has a support plate and a stop holding plate which is laterally laid across the pair of movable rails via a hinge and engages with the lower side of the rail support plate.

[0006]

In the present invention having the above-described structure, when the door and the movable rail are pulled out, the stop holding plate comes into contact with the rail supporting plate to stop, and the tip of the stop holding plate enters the lower side of the rail supporting plate. . Therefore, the weight of the door, the movable rail, and the refrigerated product that are pulled out are moment-supported at three points: the rolling bearing roller, the guide roller, and the rail support plate.

[0007]

【Example】

 Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which the same reference numerals indicate the same or corresponding parts. FIG. 1 is an overall perspective view of a refrigerator 10 according to the present invention, in which a main body 11 is supported by four legs 13 and an upper portion is covered with a top plate 15. The refrigerating device and the like are provided behind the front panel 19 having the air filter 17. The refrigerating compartment is configured as six drawers 20. Of course, the number of drawers 20 is not limited to this, and may be appropriately selected according to the purpose of use. 2 is a perspective view showing a state in which the drawer 20 is pulled out, and FIG. 3 is a vertical sectional view of the pulled out portion. 2 and 3, the front surface of the drawer 20 is a door 21 having a heat insulating structure (drawer door), a door packing 23 is attached around the inside thereof, and a pair of movable rails 25 and 26 are further connected. There is. A guide roller (rolling roller) 28 is rotatably supported at the inner ends of the movable rails 25 and 26 via a fixed frame described later. The proposed roller 28 rolls on a fixed rail described later.

Referring to FIG. 4 showing an overall perspective view of the drawer 20, a handle 21a is provided on the front surface of the door 21, and the rear ends of the movable rails 25 and 26 are connected by a fixed frame 31, and the side surfaces thereof are connected to each other. A roller 28 is pivotally supported. The upper part of the fixed frame 31 is connected to the upper part of the inner surface of the door 21 via the storage case frames 33 and 34, and the drawer 20 is made solid. A box-shaped storage case a (see FIG. 3) is placed on the storage case frames 33 and 34, and stoppers 25a and 26a for restricting movement of the storage case a to the inner side are provided on the movable rails 25 and 26, respectively. There is. Further, a stop holding plate or stopper 38 is pivotally provided on the lower portion of the fixed frame 31 via a hinge 36.

The fixed rail and the rolling bearing rollers provided in the storage portion of the refrigerator body 11 are configured as a rail body assembly 40 in consideration of manufacturability (FIG. 5). In FIG. 5, the fixed rails (horizontal fixed rails) 41 and 42 that face each other extend in parallel, and the rear ends are connected to each other by a connection fixing frame 44. The connection fixing frame 44 is fixed to the inner rear end surface of the refrigerator main body 11 by an appropriate fastener. Rail mounting plates 46 and 47 are respectively fixed to the entrance side ends of the fixed rails 41 and 42, and these are connected by a rail supporting plate 49. Rolling bearing rollers 51 are rotatably supported on the inner surfaces of the rail mounting plates 46 and 47. Further, the rail mounting plates 46 and 47 are connected at their lower portions by a rail supporting plate 49, and the rail body assembly 40 is constructed as a rigid four-frame frame.

FIG. 6 shows a state in which the drawer 20 and the rail body assembly 40 are assembled. FIG. 6 shows a case where the drawer 20 is pulled out as shown in FIGS. 2 and 3, and when the door 21 is pushed all the way to the right side in FIG. The part (the part excluding the door 21) is retracted. In FIG. 6, the stopper 38 is in contact with the rail support plate 49, but if the drawer 20 is returned slightly to the right and the hinge 36 is rotated clockwise around its rotation axis, the stopper 38 will be Comes above board 49. In this state, if the drawer 20 is pulled out again, the stopper 38 does not operate and the drawer 20 can be separated from the rail main body assembly 40 and thus the main body 11.

In the above description, considering the manufacturability (assemblability) as described above, the fixed rails 41, 42, the rolling bearings 51, etc. are the rail body assembly 40 as a sub-assembly, but of course, The fixed rails 41 and 42 have the same function even if the roller 51 and the rail support plate 49 are individually attached and fixed to the inner surface of the refrigerator main body 11.

Returning to FIG. 3 again, a description will be given of how the load is applied when the drawer 20 is pulled out to the outermost position (the stopper 38 hits the rail support plate 49). The weight of the refrigerating material in the drawer 20 and the storage case a acts about the roller 51 as a counterclockwise moment. The roller 28 hits the fixed rails 41, 42 and bears part of the aforementioned moment. Further, since the stopper 38 is inserted into the lower side of the rail support plate 49, this portion also supports the moment.

[0013]

[Effect of device]

 As described above, since the weight of the drawer and the weight of the refrigerated product when the drawer is pulled out are supported by the three points of the rollers 28, 51 and the stopper 38, the horizontal distance between the roller 28 and the roller 51 can be shortened. By doing so, the maximum withdrawal amount can be increased compared to the conventional one, and the refrigerated items can be taken out easily. Furthermore, since the stopper can be easily rotated to the inoperative position by turning the hinge, the drawer can be easily removed and the inside can be easily cleaned.
