Conventionally (1, 11), the inner part is formed of plastic, and the side plate part is formed by bending the four sides of the outer part, and the four regular sides of the inner plate are bent at several parts on the west side. To prevent screws, the structure was such that a heat insulating material was filled between the outer door panel and the inner panel.-A gasket was installed around the inner panel using the so-called pop-in method.

という問題があった。Since the west side of the door outer panel is bent to form the side (ru) part, a bending mold of a size that matches the size of the door outer panel is required, and the "horizontal" method is the same. If C and vertical = J pay are different, a separate mold must be prepared for that purpose, which increases the cost of manufacturing the door outer panel and, ultimately, the heat insulating door.Also, there is a problem in that the cost of manufacturing the door outer panel and the insulated door increases. (Since the opening width of the J groove is narrower than the width of the depth, it is difficult to mold the inside of the J groove, especially when molding the inner panel of a doll's door.) However, there was a problem in that it was no longer possible to perform the so-called snap-in method C. f = J (j).

。In the present invention, a side plate portion is formed by bending one set of corresponding both sides out of the four sides of a door outer plate, and a side frame is attached to the remaining set of corresponding both sides. When the four sides of the inner plate of a door having four steps are attached to the side plate and side frame, the opening becomes narrower than the back due to the cooperation of the recessed step, the side plate, and the side frame. By covering with the structure that forms one groove, the outer plate has the same dimensions on either the vertical or horizontal side (if available, the usage is 1 or 5' + 5'

いようにしている。Reference numerals 3 and 4 denote two side frames made of Plus Deck, and both of these side frames 3 and 4 are in the shape of a long and narrow rectangular container with one side open. A claw 6 corresponding to the small hole 5 is provided in a protruding manner, and protrusions 7.8 are provided on the inner pallet surface to face each other at a predetermined interval on both sides 13a, 31) and 4a, 4b along the longitudinal direction. It is protruded intermittently. Reference numeral 9 designates an interior plate made of plastic, which has a protrusion 9a for forming and covering a pocket for storing bottles and the like. A flange 11 corresponding to a four-step part is extended through a falling part 10 on the four sides of the door inner plate 9, and two corresponding sides along the longitudinal direction of the four sides of this flange 11 are provided. A rising portion 13 is provided upright between the above-mentioned falling portion 10 (J-concave portion 12 is formed), and this rising portion 13 is
A pressure contact plate portion 14 is provided to extend outward at the tip end edge of the pressure contact plate portion 14 . In this case, both the falling portion 10 and the rising portion 13 are formed so as to be inclined diagonally outward, thereby making it easier to remove the mold from the mold.

間を塞ぐようにする。Next, we will explain the procedure for manufacturing a heat insulating door using each part of the above structure. First, attach the side frame 3 to one side of the set of songs on the door outer panel 1, that is, to the back of both sides in the longitudinal direction.
J and Uniruru block the gap between the two opposite sides. In this case, the side frame 33 is placed over the outside of the stone outer plate 1, and the claws 6 on both sides thereof are elastically engaged with the small holes 5 of the side plate parts 2 on both sides, as shown in FIG. , the side frame 3 is attached in a manner that prevents it from coming off. Thereafter, as shown in FIG. 3, the inner panel 9 is inserted into the outer panel 1 from the other unclosed longitudinal side of the outer panel 1. Of the flanges 11 on both sides in the longitudinal direction of the C1 door inner plate 9, the flange '11 on this side that is inserted first is placed on the projecting piece 7 of the side frame 3. Then, since the height of the rising portion 13 is determined to be larger than the distance dimension 11 between the protruding piece 7 and the holding plate portion 2a, the height of the rising portion 13 is set at two points in FIG. 3 (') It is elastically deformed from the state shown by the I line to the state shown by the solid line C, and the elastic force C presses the pressing plate part 14 against the holding plate part 2a. Of these, attach the side frame 1 to the other side and -C1 both side plate parts 2
Try to close the gap.

The flange on the other side is placed on the protruding piece 7 of the side frame 4, and the flanges 11 on both sides in the longitudinal direction are both supported by the protruding piece 7, so that the pressure contact plate part 14 covers almost its entire length. It comes into pressure contact with the holding plate portion 2a. On the other hand, the retaining plate portion 2a of the door outer panel 1 faces into the concave portion 12 of the door inner panel 9 and partially blocks the opening from the outside, and as a result, the retaining plate portion 2a of the door outer panel 1 side Part 2

And the width of the lower part 21a between the flange '1'1 and the cooperator-C1 is 1. ) A narrow angle gap 21 is formed.

も済む等の優れた効果を奏する。(Effects of the Invention) Is it clear from the above description that the present invention forms side plate parts by bending them only on one set of both sides corresponding to the openings on the west side of the tenon on the outer panel of the door? By making the mold for bending the side plate with the longest side of the back of the side plate of each type of outer plate and placing it in place, you can make the vertical and If one of the side panels has the same door outer panel, the side panels can be bent and formed using the same mold even if the dimensions of the other panel are different. Therefore, the versatility of the bending mold is increased, and the manufacturing cost of the door outer panel and heat door is reduced to 1.
can be reduced. In addition, since the mounting groove is formed by the cooperation between the internal panel, the door outer panel, and the side frame, there is no need to pre-form a narrow mounting groove inside the door, and therefore the doll Gaskets can be easily installed using the so-called snap-in method. Furthermore, after installing the gasket, 1 l Ji
F,! Even if 19 people were inside the room, the sealing action of the retaining part of the cassette l- would prevent it from leaking outside. Do not seal too tightly between the outer panel of the door, the side frame, and the inner panel! It has excellent effects such as being able to use it without any hassle.
