DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction gasket, and more particularly to a construction gasket excellent in installation workability and prevention of falling out.

[0002]

2. Description of the Related Art Gaskets conventionally used in buildings include, for example, a gasket interposed between a sash for a window frame of a house and a wall surface of a building and a gasket interposed between a sash and glass, panels, and the like. For example, there is known an embodiment in which a gasket is pushed into a panel having a substantially U-shaped cross section.

[0003]

In the above-mentioned embodiment in which the gasket is pushed into the panel having a substantially U-shaped cross section, there is a problem that it is difficult to mount the sash or panel for a window frame. There is a drawback that the gasket is easily detached when installing. The present invention in view of their circumstances, good attachment workability, Pas
It has been developed with the aim of providing an architectural gasket that is difficult to remove once it is attached to the flannel .

[0004]

The present invention employs the following technical means to solve the above-mentioned problems.

[0005] An elongated extruded body, the cross-section of which
Along the length between the front base and the rear sub-section
The fitting groove is formed and the engaging part is formed in a substantially U-shaped cross section.
The main contact portion is integrally formed on the front surface of the base of the engagement portion.
In each of the opposed wall surfaces of the base and the sub-portion in the fitting groove,
Several parallel relief grooves are formed deeper from the opposite wall along the length
Made is, the base and the opposing wall partitioned by relief grooves of the secondary portion
At each base end of the surface , a press contact ridge is
An architectural gasket protruding along each side wall toward each opposing wall .

[0006] An elongated extruded body, the cross-section of which is
The fitting groove is opened between the front base and the rear sub-section.
With the mouth facing down, it is formed along the length and has a substantially U-shaped cross section
An engaging portion is formed on the main body, and a main contact portion is integrated with the upper portion of the engaging portion.
Is formed on the upper surface of the contact main portion, and a foreign material is fitted on the upper surface of the contact main portion.
The compound is buried, and each pair of the base and the sub-portion in the fitting groove is provided.
On the facing wall, there are multiple parallel relief grooves along the length
Formed deep from the surface and separated by the relief grooves of the base and sub-portions.
The base end of each opposing wall
A ridge is provided along the side wall of the escape groove toward each opposing wall.
Building gasket .

The engaging portion faces the base with the fitting groove interposed therebetween.
Sub part, the tip is inclined about 10 degrees closer to the base.
Can be formed.

[0008]

According to the present invention constructed as described above, the following operations are provided. That is, the substantially U-shaped engaging portion can fit the fitting groove outside the sash, the panel, or the like, but easily comes out of the sash, the panel, or the like as it is. However, in this invention, the opposing wall surface of the base portion and the secondary portion of the substantially U-shaped engaging portion, each of a plurality of relief grooves pressure
Since the contact ridges are formed long and parallel to the longitudinal direction, when a sash, a panel, etc. are pushed into the fitting groove, each pressure contact ridge falls down from the root and sinks in the escape groove, so that Since the panel is strongly pressed by the repulsive force, it is difficult for the panel to come out. Also when trying to pull out the panel,
The repulsive force of each press-contact ridge increases the frictional resistance with the panel, and a force is exerted to wind the tip of each press-contact ridge.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a building gasket. The building gasket 1 is an elongated member mainly formed by extrusion molding made of silicone rubber, and an engaging portion 3 having a substantially U-shaped cross section is integrally formed on the back side (lower side in the figure) of the contact main portion 2 having a substantially dome-shaped hollow cross section . Then, a fitting groove 4 is formed in the engaging portion 3. A pair of a main part 3A and a sub part 3B constituting the fitting groove 4
The width between the facing walls is at the base end as shown in FIG.
Slightly wider than the width of the panel 5 to be fitted
But the secondary portion 3B mouth portion of the fitting groove 4 tip about 10 degrees with respect to (the lower side in the figure) rear surface of the inner surface of base portion 3A is in <br/> inclination of the engaging portion 3 is The width is set smaller than the width of the panel 5 . Base portion 3A and the secondary portion 3B of the opposed walls face each of the plurality of relief grooves 3C on ..., 3D ... is longer parallel to the longitudinal
Formed deeper from the opposite wall,該逃up groove 3C ..., 3D ... outer portion pressing protrusion is protruded into the fitting groove 4 in the direction from the opposite wall along the 3E of ..., 3F ... are formed. .., 3F... In the depth direction of the fitting groove 4 (the base end portion).
Direction) . Also in the figure
As described above, the escape grooves 3C, 3D are formed by pressing projections 3E, 3E.
It is set larger than the cross-sectional area of F ...

In the above embodiment, when the fitting groove 4 is externally fitted to a panel 5 previously fixed to a building, FIG.
Each pressure contact projections 3E as shown in ..., 3F ... has a base portion 3A
Since the panel 5 protrudes from the opposing wall surface of the sub part 3B into the fitting groove 4 at a position smaller than the width of the panel 5, the panel 5 is
When it enters, the tip of each of the pressing projections 3E, 3F sinks into each of the escape grooves 3C, 3D, and the pressing force against the panel 5 is excellent due to the repulsive force. And panel 5
When trying to pull out from the fitting groove 4, each press contact ridge 3E
, 3F, the frictional resistance with the panel 5 increases, and a force is exerted to wind the leading end of each of the pressing projections 3E, 3F. Getting out becomes difficult. Thus, the building gasket 1 can be mounted on the panel 5 with one touch, and there is an effect that there is no fear of detachment after the mounting. Further, a window frame or the like is pressed against the contact main portion 2 to maintain airtightness and watertightness.

The overall shape of the gasket 1 of the present application is not limited to this shape. For example, as shown in FIG. 3, the shape of the contact main portion 2 and the connection between the engaging portion 3 and the contact main portion 2 are determined. The morphology can be changed. Symbol 2 in FIG.
A indicates a fitting having a material different from that of the surroundings (for example, soft raw rubber).

[0012]

The present invention configured as described above has the following excellent effects.

A. In the fitting groove of the substantially U-shaped engagement portion,
Panel since for pressure ridges have clearance groove respectively formed on the opposing wall surface of the base portion and the secondary portion are projected, when mounting the panel to the fitting groove is sinking into the groove escape pressure ridges There is an effect that can be attached with one touch.

B. In the fitting groove of the substantially U-shaped engagement portion,
Pressure ridges have clearance groove respectively formed on the opposing wall surface of the base portion and the secondary portion is projected, when mounting the panel in the fitting groove in order to sink into the groove escape pressure ridges, and will pull out the panel Then, since the pressing projection presses the panel by the repulsive force and acts to be involved, the frictional force is increased and there is an effect that it is difficult to remove the panel.

C. Since the shape is simple and extrusion molding can be performed, there is an effect that the production cost is not burdened.

D. In the case where the substantially U-shaped engagement portion is a side fitting type,
When the window frame sash is mounted from the side, there is an effect that the building gasket does not come off.
