Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a gasket used for refrigerator doors and the like.

[Technical background of the invention]

For example, in a refrigerated vehicle, the door is equipped with a gasket, and this gasket is fixed to the door by pressure detection between the outer door panel and the inner door panel, by adhesive fixation to the door inner panel, or by fixing it with screws. It is designed to be installed on.

[Problems with background technology]

However, in the above-mentioned gasket, the gasket is fixedly installed, so when the gasket deteriorates and it becomes necessary to replace the gasket, as in the case of 9, it is difficult to remove the gasket. Even if it could be removed temporarily, the process was troublesome, and furthermore, installing a new spare gasket F afterward required troublesome work such as pressure detection fixing, gluing, or screwing.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a gasket that allows all operations from removal to attachment of a spare gasket to be easily performed.

[Summary of the invention]

The present invention is characterized in that a hard mounting base portion and an elastic, soft gasket main body portion are integrally molded, and a hole portion for fitting a spare gasket is formed in the mounting base portion.

[Embodiments of the invention]

Hereinafter, a first embodiment of the present invention applied to a door side gasket of a refrigerated vehicle will be described with reference to FIGS. 1 to 5.

First, in Fig. 1, 1 is the door of the cold storage, 2 is the outer panel of the door, 5 is the inner panel of the door, 4 is the foam insulation material filled between the outer door panel 2 and the inner door panel 3, and 5 is the door of the cold storage. This is a sheet that crushes the surface of the foam insulation material 4 in the door inner panel SS. Now, 6 is the gasket,
This is constructed by integrally molding a mounting base part 7 made of a hard plastic snack and a gasket body part 8 made of an elastic soft plastic by co-extrusion molding. The mounting base 7 is formed with a groove-shaped hole 9 whose opening end is narrow, and slit-shaped fitting recesses 10 and 11 are formed on the left and right sides of the groove-shaped hole 9. ing. A curved portion 81 and fin portions 8b and 8e are formed in the gasket main body portion 8, and a magnet 12 made by KM is embedded therein by co-extrusion molding. Such a gasket 6 has a fitting recess 10
is attached to the end of the door outer plate 2, and the fitting recess 11 is fitted to the end of the door inner plate 3, thereby being attached to the door 1.

For example, if the gasket main body 8 deteriorates and needs to be replaced, the boundary between the soft gasket main body 8 and the hard mounting base 7 is cut with a cutter or the like. . In this case, the soft gasket main body part 8 can be cut while using the hard mounting base part 7 as a guide for the cutter, so the cutting operation can be easily performed, and the gasket main body part 8 can be neatly cut off from its edge. can.

Then, the gasket main body 8 is removed by cutting off the gasket main body 8. This state is shown in Figure 2. After that, as shown in Figure 5, the spare gasket 15 having the insertion protrusion 14 on the gasket main body 15 is fitted by inserting the insertion protrusion 14 into the hole 9 of the mounting base 7. Attach it to the mounting base part 7.

According to this embodiment, the gasket can be removed by cutting off the gasket main body 8, which makes it difficult to remove the gasket and can be removed temporarily. Unlike the conventional case, removal work is easy. Moreover, since the mounting base part 7 is made hard and the gasket body part 8 is made elastic and soft, the soft gasket body part 8 can be cut while using the hard mounting base part 7 as a guide for the cutter. The gasket main body 8 can be cut off easily and the gasket main body 8 can be cut off cleanly.
Since it is cut, it does not require much force. In addition, the mounting base part 7
Since #IK is left in place, when removing the mounting base 7, there is a risk that the foam insulation material 4 inside the door 1 may fall off or the edges of the door outer panel 2 and the door inner panel 5 may bend. On the other hand, no such problem occurs. Furthermore, a hole 9 for fitting the spare gasket 15 is formed in the mounting base 7 so that the spare gasket 15 can be mounted with one touch.
The installation of the spare gasket 15 is also easy in the dormitory, and all the work from removal to installation of the spare gasket 15 can be easily performed in one dormitory.

Next, FIG. 4 shows a second example of the present invention. In the second example, the mounting base portion 16 also serves as a decorative frame, and together with the door outer panel 2 and the refrigerator inner panel 3, Although this embodiment differs from the first embodiment in that the outer shell of the second embodiment is configured, the same effects as those of the first embodiment can be achieved.

In each of the above embodiments, the present invention was applied to a gasket on the door side of a refrigerator, but the present invention is not limited to this and can be widely applied to other gaskets in general, and may be applied to other gaskets without departing from the scope of the invention. It can be implemented with various modifications.

〔Effect of the invention〕

As explained above, the present invention has the advantage that all operations from removal to spare gasket attachment can be easily performed in the dormitory.
