Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an auxiliary case support device for a refrigerator that is provided so that an auxiliary case such as a meat plate can be pulled out via a rail.

(Prior Art) Conventionally, some refrigerators have an auxiliary case, for example, a meat plate, which is removably disposed above the refrigerator compartment. In this device, rails facing left and right are provided on the lower surface of the shelf board arranged below the cooler so as to protrude downward, and the meat plate is engaged and supported by the rails so that the meat plate can be pulled out, and the limits of the drawer are determined. A stopper is fixed to the bottom surface of the shelf with multiple screws to prevent it from falling off due to over-drawing.

(Problems to be Solved by the Invention) However, according to the above structure, since the stopper is fixed with screws, there is a problem in that the number of assembly steps is large.

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to provide an auxiliary case support device for a refrigerator that does not require or eliminate screws for attaching a stopper.

[Structure of the invention] (Means for solving the problem) The auxiliary case support device for a refrigerator of the present invention is integrally molded with a running part so as to protrude in a substantially horizontal direction so that the auxiliary case can be supported on the rail part in a freely running manner. A protrusion having an engagement hole opening in the direction in which the running portion protrudes is integrally formed on the shelf board together with the rail portion,
By supporting the stopper using the engagement hole of this protrusion, the number of screws can be eliminated or eliminated.

(Function) According to the auxiliary case supporting device for a refrigerator of the present invention, when the auxiliary case is pulled out to its drawer limit by the engaging protrusion of the auxiliary case moving on the running part of the rail, a part of the auxiliary case comes into contact with the stopper.

(Example) An example of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a refrigerator main body, and a refrigerating compartment 2a with a door 2 above it.
A refrigerating room 3 is formed below, which also has a door (not shown). The top of the refrigerator compartment 3 is a cooler arrangement room 4, and a shelf board 5 is arranged below it.
An auxiliary case, that is, a meat plate 6 is disposed on the lower surface of the shelf board 5 so as to be able to be pulled out forward. A large number of cold air passage holes 7 are formed in the right half of the shelf board 5, and a pair of rails 8, 9 facing left and right are provided on the lower surface of the left half by integral molding so as to protrude downward. ing. The rails 8 and 9 have running portions 8a and 9a oriented in the front-rear direction by forming their lower ends to protrude substantially horizontally so as to approach each other. That is, the running portion 8a,
The rails 8 and 9 having 9a are formed by a mold that integrally molds the shelf board 5 in the vertical direction (in FIG. 3) and a movable mold placed inside the mold. It is integrally molded with. The meat plate 6 is made of plastic and has a shallow container shape with an open top, and has engaging protrusions 10 on both side walls.
a, 10b, and these engaging protrusions 10a, 10
b is slidably placed on the running parts 8a, 9a, that is, movably, so that the meat plate 6 is placed on the rails 8, 9.
It is attached to the shelf board 5 via a drawer. In the lower surface of such a shelf board 5, each of the running portions 8a, 9
A pair of protrusions 12 having engagement holes 11 are integrally molded in the portion facing a. These projections 12 are formed by the movable molds that form the rails 8 and 9, and the engagement holes 11 are formed so that the movable molds can escape from the undercut shapes of the running parts 8a and 9a of the rails 8 and 9. Since the mold structure is such that the mold is removed by sliding in the direction of the arrow 13 (only one is shown), the structure is opened in the direction in which the running portions 8a and 9a protrude. 14 is a boss, which is formed on the shelf board 5 by integral molding with the mold at a position facing the engagement hole 11 of each protrusion 12; in this case,
The molding portion of the boss 14 in the mold is located inward (in the direction of arrow 13) from the movable mold. 15
is a hollow plastic stopper, which has an insertion protrusion 16 inserted into the engagement hole 11 of the protrusion 12 at one end, and a screw insertion hole 17 at the other end. is forming. Here, in the stopper shown in FIG. 5, reference numeral 18 is a clearance space, and reference numeral 19 is a groove in which the boss 14 can move relative to each other. The stopper 15 has its insertion protrusion 16 inserted into the engagement hole 11 of the protrusion 12 to be in an engaged state, and after the boss 14 is inserted into the groove 19, the screw 20 is inserted into the screw insertion hole 11.
7 into the boss 14, and thereby the stopper 15 is attached to the lower surface of the shelf board 5. As a result, when the meat plate 6 is pulled out forward, the inner surface of the rear wall of the meat plate 6 finally hits the stopper 15, thus setting the limit of the draw-out and preventing it from falling off the rails 8, 9.

According to the above structure, the insertion protrusion 16, which is a part of the stopper 15, is engaged with the engagement hole 11 of the protrusion 12 by insertion, thereby providing a holding action.
Only one screw 20 is needed to prevent the stopper 15 from rattling and from rotating. Of course, depending on the length of the engagement hole and the size of the stopper, it is possible to eliminate the need for a screw.

By the way, it is also conceivable to integrally mold the stopper 15 on the lower surface of the shelf board 5. In this case, the stopper 15 comes into contact with the inner surface of the rear wall of the meat tray 6 in order to determine the limit for pulling out the meat tray 6, so it is necessary to increase the mechanical strength and the rear wall of the meat tray 6 needs to be strong. Since the area of contact with the inner surface needs to be relatively large, it is necessary to make it larger than the boss 14. When such a large stopper 15 is integrally molded on the lower surface of the shelf board 5, the shelf board 5
There is a problem in that a sink mark occurs on the upper surface of the stopper 15 corresponding to the stopper 15, resulting in an unsightly appearance. In order to prevent this kind of sinkage from occurring, the stopper 15 can be hollowed out, but if this is done, the holes (18 and 19 in FIG. (equivalent) will be formed, which will also make it look unsightly. Therefore, conventionally,
The stopper is not integrally molded to the shelf board, but a separate piece of stopper is used. Conventionally, a plurality of bosses similar to the boss 14 are integrally molded on the lower surface of the shelf board, and stoppers are screwed to these bosses.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and fasteners may be used instead of screws for fixing the stopper.

[Effects of the Invention] As described above, the present invention can provide an auxiliary case support device for a refrigerator that does not require or eliminate screws for attaching a stopper that prevents the auxiliary case from being pulled out too much.
