Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint type fixed gasket that fits into joints of an outer wall of a building, the tip of which is inserted into the gap between the bodies so as not to tilt (roll over) to either the left or right side during insertion. It is a thing.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 1 and FIG. 2, the joint portion 2 formed at the connection portion of the outer walls 1, 1 stretched outside the building is provided with, for example, the joint portion 2 outside in order to prevent water from entering the building. A central leg portion 5 is joined to the cover portion 4 covering from the side in a T-shape, and a plurality of steps of main seal lips 6, 6 extending toward the end faces of the outer walls 1, 1 are provided on both sides of the central leg portion 5 so as to project. The auxiliary seal lips 7 and 7 for closing the gap between the precursors 3 and 3 are provided on both sides of the inner leg side of the main seal lip 6 of the central leg portion 5 so as not to incline to either the right or the left when being inserted (rolling). As shown in the figure, a standard gasket formed by projecting rolling prevention lips 8 and 8 extending toward the driving bodies 3 and 3 is fitted on both sides of the tip of the central leg portion 5 (actual flat 2-1 25127). (See the official gazette).

However, when the conventional standard gasket is inserted into the joint portion 2 of the outer walls 1 and 1, there is a variation in the gap between the precursors 3 and 3, and the standard gasket has an internal structure as shown in FIG. There is a problem that the appearance may be impaired because it may fall into the back side or, on the contrary, it may float up toward the front side (not shown) due to difficulty in insertion.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that when the conventional standard gasket is inserted into the joint part 2, the standard gasket falls into the inner depth side, or conversely, it floats to the front side because it is difficult to insert. May be impaired.

[0005]

Means for Solving the Problem An explanation will be given with reference to FIGS. 3 and 4. The present invention is directed to the inner inner side of the main seal lips 6 and 6 projecting on both sides of the central leg portion 5 which is fitted to the joint portion 2 formed at the connecting portion of the outer walls 1 and 1 stretched outside the building. It is a standard gasket that has auxiliary seal lips 7 and 7 that close the gap between the precursors 3 and 3 on both sides of the Positioning projections 9, 9 are provided on both sides of the central leg portion between the lip 6 and the auxiliary seal lip 7.

[0006]

【Example】

 Explaining an example, 1, 1 is an outer wall of a building, and an outer wall stretched over an L-shaped cross section of a vehicle 3, 3, and 2 is a joint portion formed at a connection portion of the outer wall 1, 1. is there. The gap W between the precursors 3 and 3 is smaller than the gap in the joint portion 2. A standard gasket made of rubber or rubber-like elastic material that is fitted to prevent water from entering the building is constructed as follows. 4 is a cover portion that covers the joint portion 2 from the outside, 5 is a central leg portion joined to the cover portion 4 in a T-shape, and 6 is a branch from both sides of the central leg portion 5 toward the end faces of the outer walls 1, 1. A plurality of projecting main seal lips, 7 are auxiliary seal lips that close the gap W between the propulsion bodies 3, 3 when projecting on both inner inner sides of the main seal lip 6, and 8 are both sides of the central leg portion 5. The anti-rolling lip 9 projecting from the tip is a positioning projection provided on both sides of the central leg portion 5 between the main seal lip 6 and the sub seal lip 7. The standard gasket is made of black rubber or rubber-like elastic material, but the surface layer 4a of the cover portion 4 and the tip surface layer portion 6a of the main seal lip 6 on the side closer to the cover portion 4 have the same color as the outer wall 1. Or consist of rubber-like elastic body.

[0007]

[Action]

 To explain the operation, the fall prevention lip 8 and the tip of the central leg portion 5 of the standard gasket are inserted into the gaps between the bodies 3 and 3, and then the sub seal lip 7 and the main seal lips 6 of a plurality of stages are attached to the outer wall 1. , 1 into the joint portion 2. Then, the auxiliary seal lip 7 is supported from the back side by the positioning projection 9 and is compressed without being squeezed and comes into contact with the outer surfaces of the propulsion bodies 3 and 3, so that the insertion depth becomes constant and It does not fall into the back side, and if the gap between the bodies 3, 3 is made slightly larger, it does not float up, the appearance is significantly improved, and the waterproofness is secured.

[0008]

[Effect of the device]

 Since the present invention is configured as described above, the positioning projection 9 makes the insertion depth constant, does not fall inward, and does not float up, and the appearance is significantly improved. Water resistance is also ensured.
