Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a door gas care holding structure attached to a refrigerator door.

Conventional Structure and Problems Conventionally, for example, the structure shown in FIG. 3 is known as a holding structure for a door gasket of a refrigerator. That is, in this figure, the door gasket 1 has a contact part 9 housing a magnet 8 to be brought into close contact with the opening edge 2 of the refrigerator, a buffer part 1o, and a buffer part 1o.
It is composed of a base part 12 and an insertion part 11 that is inserted into a substantially trapezoidal mounting end formed on the inner surface of h3, and the insertion part 11 is inserted into the inner wall surface of the mounting groove 7. The opening of the mounting groove 7 is sandwiched in between, thereby preventing the mounting groove from falling off or coming off. However, in the above conventional example, the mounting groove 7. Errors during molding of the insertion portion 11;
Inner plate 5 or heat insulating material 6 for cooling during use of the refrigerator
There was a risk that the mounting groove 7 would easily fall off due to dimensional errors caused by movement of the mounting groove 7 due to expansion and contraction. Further, when inserting the insertion portion 11 into the mounting groove 7, the insertion portion 11 has a shape that is already equal to the inner wall surface shape of the mounting groove 7, so that the insertion work is difficult.

OBJECTS OF THE INVENTION The present invention has been made to solve these drawbacks, and its object is to prevent the door gasket from coming off.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention forms a gasket insertion portion in the shape of a bag, and forms the bottom of the bag and the convex portion formed on the bottom with a hard material. The dimensions are set to the opening width of the gasket mounting groove, and the height of the convex portion is smaller than the opening width to strengthen the tight contact between the bag-shaped portion and the gasket receiving groove. 0 Description of an Embodiment Below, an embodiment of the present invention will be described with reference to FIGS. do. In the figure, 23 is a door gasket formed by extrusion molding of soft vinyl chloride or the like.

2 is a refrigerator that is sealed by this door gasket 23, and 22 is a door that is attached to the refrigerator 2 so as to be openable and closable. The door gasket 23 is attached to the periphery of the door 22. As is well known, h22 includes an outer plate 21 made of steel plate or the like;
An inner plate 20 made of synthetic resin or the like, and both of these plates 21.20
It is composed of a heat insulating material 6 filled in between. Inside the door 22 θ) On the other hand, the door gasket 23 is connected to the close contact portion 17 that houses the magnet 18 so that the door 2 is in close contact with the opening 2 of the refrigerator 2.
2. Consisting of a buffer section 16 that acts as a buffer when opening and closing, a seal section 15 formed by a fin to abut against the inner surface plate 20, a base section 14, and an insertion section 13 that is inserted into the bottomed mounting groove 19. has been done.

Furthermore, the insertion part 13 is formed of a bag-like part 13a having a shape almost the same as the size of the inner wall surface of the bottomed mounting groove 19, a bottom part 13b of the bag-like part 13a of the casting, and convex parts t and 113C of the bottom part. Bottom part 13b and bottom convex part 1 phantom.

130 is a hard material, the buffer part 16, the seal part 16 and the base 1
4, the bottom part 13b of the insertion part 13, and the convex part 130 at the bottom are made of a soft material f co-extruded.
] B is formed so that rlJ is wider than rlJ8 of the opening, and the convex part 130 at the bottom abuts the bottom side 19' of the bottomed mounting groove and pushes up the bottom part 13b and comes into close contact with the side wall of the bottomed mounting groove 19. It is formed like this. In addition, the height C of the convex portion 13C+ at the bottom is dimensioned to be smaller than i]A of the opening.

Next, the operation of the above embodiment will be explained. In the figure, when the insertion part 13 is inserted into the bottomed mounting groove 19, the bottom part 13b is lifted up by the convex part 13c on the bottom and comes into contact with the inclined wall surface of the bottomed mounting groove 19, as shown in FIG. It becomes a stop. In this embodiment, it goes without saying that removal is prevented due to the relationship between the width B of the bottom 13b and the width A of the opening;
is pressed to lift the bottom portion 13b, and the insertion portion 13 is fixed within the bottomed mounting groove 19 by being pressed against the inclined side surface of the bottomed mounting groove 19.

Further, when inserting the insertion part 13 into the bottomed mounting groove 19, the insertion part 13 is inserted in an inclined state so that it can be inserted into the opening of the width, as shown in FIG. Convex part 1 on the bottom
Since the height C of 3c is smaller than the opening A, it can be easily inserted into the opening.

Effects of the Invention As described above, the present invention forms the insertion portion of the gasket into a bag shape, and the bottom of the bag and the convex portion formed at the bottom are made of a hard material. The width is set to p, and the height of the convex portion is smaller than the width of the opening mentioned above, so insertion of the gasket is easy, and the size of the bottomed mounting groove does not change in the inserted state. Or, even if there is an error between the bottomed mounting groove and the insertion part, the material at the bottom of the insertion part is harder than conventional ones, so it is difficult for the bottom part to become smaller than the width of the opening. Since the bottom is pressed and brought into close contact with the bottomed mounting groove, the possibility of it falling off is extremely reduced.

Claims (1)

[Claims] It consists of a close contact part that comes into close contact with the refrigerator body, a buffer part, a base part, and an insertion part that is inserted into a bottomed mounting groove whose opening side is narrow in a part of the door, and the insertion part is inserted into the inner wall of the bottomed mounting groove. A bag-like portion that is in close contact with the bag-like portion and a convex portion formed at the bottom of the bag-like portion are molded from a hard material, and the bottom of the bag-like portion is made larger than the opening width of the bottomed mounting groove to increase the height of the convex portion. A refrigerator door gasket holding structure in which the width is smaller than the opening width of the bottomed mounting groove and the bottom is locked in the bottomed mounting groove.
