Description

[Detailed explanation of the idea] [Technical field] The present invention relates to gaskets.

[Conventional technology]

Conventionally, as shown in FIG. 1, a gasket 3 inserted into a joint 2 of an external wall member 1 of a building, etc., has been used, as shown in Japanese Utility Model Application No. 58-64713.
A device in which a main body portion 4 having a sealing function and a T-shaped wedge-shaped protective body portion having weather resistance are constructed as separate parts is used. This gasket 3
After inserting the main body part 4 into the joint part 2, the locking part 5A of the protector part 5 is inserted into the engaging part 4A of the main body part 4, thereby sealing the joint part 2 with the main body part 4. The protector section 5 protects the main body section 4 from the external space and also makes it possible to improve the external appearance.

However, in the conventional gasket 3 described above, the main body portion 4 and the protector portion 5 are constructed as separate parts, so the insertion work of the gasket 3 is laborious twice as described above, and the insertion work is also complicated. Only one type of jig is required. In addition, when the joint width is relatively wide, the locking part 5 of the protector part 5
There is a possibility that the protector portion 5 may separate from the main body portion 4 without being reliably engaged with the engaging portion 4A of the main body portion 4. Further, storage of the gasket 3 also requires complicated handling of the two parts and a large storage space.

[Purpose of the invention] The object of the invention is to make the insertion of the gasket easy and reliable, and to improve the storage property of the gasket.

[Summary of the invention] In order to achieve the above object, the gasket according to the invention includes a gasket protector part made of a hard material having weather resistance and having an approximately T-shaped cross section, which is integrally formed on the gasket body part provided with the seal part. The seal portion includes a first seal portion made of a soft material and a second seal portion whose base portion is made of a soft material and whose end portion is made of a weather-resistant hard material. Abbreviation T for gasket protector
The second seal part is located at the lower end of the letter-shaped shaft part, the second seal part is located above the first seal part, and the end thereof is the substantially T-shaped horizontal part of the gasket protector part. It is located near the area.

[Structure of the invention] Hereinafter, embodiments of the invention will be described with reference to the drawings.

Figure 2 shows a gasket 1 according to an embodiment of the present invention.
2, the gasket 10 has a main body portion 11 and a protector portion 12 integrally formed, and is an elongated object having a continuous cross-sectional shape as shown in FIG.

The protective body part 12 is attached to the front part 1 in a T-shape.
3 and a shaft portion 14, and is made of a weather-resistant material such as high hard rubber or hard vinyl chloride resin.

The main body part 11 uses the shaft part 14 of the protector part 12 as a core material, and is integrally molded at the same time as the protector part 12,
Alternatively, it is integrally formed with the protective body portion 12 after molding. This main body portion 11 includes a shaft portion 1 of a protector portion 12.
A first seal portion 15 is provided on both sides of the tip portion of the protector portion 12, and a second seal portion 16 is provided on both sides of the intermediate portion of the shaft portion 14 of the protector portion 12. The first seal portion 15 and the base portion 16A of the second seal portion 16 are made of a material with good sealing properties such as low hardness rubber or soft synthetic resin,
The end portion 16B of the second seal portion 16 is connected to the protector portion 12.
It is made of the same color and made of materials with similar weather resistance. In addition, the first seal portion 15
and the second seal portion 16 are hollow portions 17 and 1, respectively.
It is a hollow body that forms a shape of 8, and is capable of having appropriate deformation and elasticity functions.

Note that the end portion 16B of the second seal portion 16 can come into contact with the back surface of the front portion 13 of the protector portion 12 when the gasket 10 is in use. Immediately after molding, the surface of the front part 13 of the protector part 12 is provided with a grain pattern or the like that matches the surface condition of the outer wall member to which the gasket 10 is applied, so that a desired appearance can be obtained. be done.

Next, the operation of the above embodiment will be explained.

FIG. 3 is a sectional view showing the gasket 10 inserted into the joint 2 of the outer wall member 1 of a building. The gasket 10 inserted into the joint part 2 is
The first seal part 15 and the second seal part 16 of the main body part 11 are deformed and perform a sufficient sealing function under the condition that they are pressed against the side surface of the outer wall member 1, and the front part 13 of the protector part 12 is This makes it possible to protect the main body part 11 from deterioration while facing a space and to improve the appearance. Note that if there is a gap between the front surface part 13 of the protector part 12 and the joint part 2, the weather-resistant end part 16B of the second seal part 16 also faces the external space, and the main body part 11
This makes it possible to protect the exterior of the vehicle and improve its appearance.

Therefore, to insert the gasket 10, it is sufficient to simply insert the entire gasket 10 into the joint 2, thus reducing the number of work steps and requiring only one type of jig for the insertion work. This makes the insertion work easier. In particular, in this embodiment, the shaft portion 14 of the hard protective body portion 12 is disposed at the center of the cross section of the gasket 10, and the first seal portion 15 and the second seal portion 16 are formed of hollow bodies. Therefore, the insertion work into the joint part 2 can be easily performed by simply applying pressure for insertion to the front part 13 of the protector part 12.

In addition, since the gasket 10 has the main body part 11 and the protector part 12 integrated, the protector part 12 can be attached to the main body part 1 even when the joint width is relatively large.
1, and a secure and stable insertion state into the joint part 2 is maintained. Further, the end portion 16B of the second seal portion 16 can always come into contact with the back surface of the front surface portion 13 of the protector portion 12, and the outer space and the first
The contact between the seal part 15 and the second seal part 16 with the base part 16A is cut off, so that they can be reliably protected from the external space.

Further, since the gasket 10 is made entirely of one component, it is easy to handle for storage, and the storage space can be made relatively small, thereby improving storage efficiency.

[Effects of the invention] As described above, in the gasket according to the invention, the gasket protector part made of a hard material and having a substantially T-shaped cross section is integrally formed with the gasket main body part provided with the sealing part. The fitting does not come off, making it easy to insert the fitting into the joint, and maintain a secure and stable fitting condition.

Also, since the entire device is made of one component, storage efficiency is improved.

Further, since the seal portion includes the first seal portion and the second seal portion made of a soft material, a sufficient sealing function is exhibited.

In addition, the gasket protector protects the seal portion and improves the appearance.Moreover, the end of the second seal portion is made of a weather-resistant hard material, and the approximately T-shaped horizontal portion of the gasket protector protects the seal portion. Since it is located near the rear end of the front part, this end further protects the seal part and makes it possible to improve the appearance.
