Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight device for fittings such as windows and doors.

[0002]

2. Description of the Related Art In fittings such as windows and doors made of aluminum profile or the like, the airtightness between the frame fixed to the building side and the frame of the shoji is the same as the frame or the frame of the shoji. An airtight material such as an attached airtight pile of vinyl chloride type, synthetic rubber type, wool type, polypropylene type, commonly called mohair, is pressed against the frame or frame of the shoji. The airtight material is inserted into an airtight material mounting groove provided in the longitudinal direction of the frame or the frame, and conventionally fixed by an adhesive, or fixed by caulking the frame or the frame after inserting the airtight material.

However, in fixing the airtight material with an adhesive,
It takes a long time to adhere, the work efficiency is poor, and there is a risk of seal failure due to unevenness and deviation of the adhesive force.In addition, the adhesive may stick out or adhere to other parts, resulting in poor appearance. Further, there is a problem that it is difficult to peel off the airtight material after it is fixed once, and it is difficult to replace it with a new one.

Further, in fixing the airtight material by caulking, it takes time to set it on the caulking jig and finely adjust it, and since the airtight material inserting step and the caulking step are separate steps, it takes time to move the members, resulting in poor work efficiency. In addition, there are problems that a caulking mark remains on the surface of the frame and a poor appearance occurs, and it is difficult to replace the caulking once with a new one. Furthermore, various kinds of caulking jigs or equipment such as equipment are required depending on the cross-sectional shape of the airtight material mounting groove, and the installation location and maintenance inspection are also required.

In view of the above problems, the present invention is an airtight fitting for a fitting in which the airtight material can be easily and surely fixed to the frame or the frame, the appearance is not deteriorated, and the airtight material can be easily replaced. The purpose is to provide a device.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an airtight material in an airtight material mounting groove formed in a longitudinal direction of a frame fixed to a building side or a frame of a shoji attached to the frame. In the airtightness device for fittings, the airtight material is composed of a base portion inserted into the airtight material attachment groove and a protrusion protruding outside the airtight material attachment groove, and the groove bottom portion of the airtight material attachment groove and the It is characterized in that a fixture is press-fitted between the base of the airtight material. The fixture is preferably plate-shaped, and has a structure having a projection on at least one surface and a flange on the end.

[0007]

Since the present invention has the above structure, the fixing member is fixed between the base portion of the airtight material and the bottom portion of the airtight material mounting groove to fix the airtight material mounted in the airtight material mounting groove. .

A perspective view of the end of the airtight material mounting groove of the lower frame and the airtight material, the same (D) is a perspective view showing a state in the middle of press-fitting the fixture, and the same (E) is a perspective view showing a state where the fixture is press-fitted. , (F) is a sectional view taken along line EE of (E). FIG. 2 is a vertical sectional view showing a window frame to which the airtight device for fittings according to the present invention is applied.

As shown in FIG. 2, a window frame 1 of this example is a rail 2 formed on a lower frame 2 made of an aluminum extruded frame.
The door wheels 6a and 6b of the indoor and outdoor shoji 3 are rotatably mounted on a and 2b, respectively. In the window frame 1, the lower frame 2 and the left and right vertical frames are used to ensure airtightness between the outdoors and the room. This is performed by inserting the airtight material 4 into the airtight material mounting groove 2c formed in the longitudinal direction (not shown) and the upper frame (not shown) and pressing the airtight material 4 against the frame 3a of the shoji 3. Further, in the present invention, as described below, the fixing of the airtight member 4 is performed by press fitting the fixing member 5 into the groove 2c.

Further, as shown in FIG. 1C, the airtight material 4
Is produced by extrusion molding or the like, and in this example, an eave-shaped protrusion 4b is formed over the entire length in the longitudinal direction of the plate surface of the plate-shaped base 4a. FIG. 1 (A),
As shown in (B), the fixture 5 is formed by pressing a thin metal plate such as stainless steel, and one end 5e of the substrate 5a is formed in an arc shape for easy insertion. Then
A flange portion 5b is formed on the other side, and claw-shaped projections 5c and 5d are formed by cutting and raising on the front and back surfaces of the substrate 5a.

To install the airtight material 4 in the airtight material mounting groove 2c, as shown in FIGS. 1C to 1E, first, from the end of the airtight material mounting groove 2c, move the airtight material 4 in the arrow Z direction. And slide it into the airtight material mounting groove 2c. Next, the fixture 5 is inserted into the gap between the groove bottom portion of the airtight material mounting groove 2c and the base portion 4a of the inserted airtight material 4, and the flange portion 5b of the fixture 5 is lightly tapped with a hammer or the like to press the flange portion. 5b is made flush with the end of the airtight material mounting groove 2c.

As described above, when the airtight material 4 is attached, the fixture 5 is fitted between the airtight material 4 and the groove 2c, and the airtight material 4 is compressed, so that the airtight material 4 is placed in the groove 2c. Fixed. Further, as shown in FIG. 1 (F), while the protrusion 5d of the fixture 5 is caught by the base 4a of the airtight material 4,
Since the protrusion 5c is pressed against the groove bottom of the airtight material mounting groove 2c, the airtight material 4 and the fixture 5 are firmly fixed to each other and the fixture 5 is firmly fixed to the airtight material attachment groove 2c.

In this way, the fixture 5 is attached to the airtight material mounting groove 2c.
By press-fitting into the lower frame 2, the airtight material 4 can be easily and reliably fixed to the lower frame 2 without causing a defective appearance. Further, by removing the fixing tool 5, the airtight material 4 can be easily removed from the airtight material mounting groove 2c. The flange 5b facilitates removal of the fixture 5 with a screwdriver or the like.

In the above description, the example in which the airtight material 4 is attached to the frame side is shown, but the airtight material 4 may be attached to the frame of the shoji screen 3. Other than the above embodiments, various changes and additions can be made to the structure and combination of the airtight material mounting groove, the airtight material, and the fixing tool without departing from the scope of the present invention.

[0015]

According to the first aspect of the present invention, the fixing of the airtight material to the airtight material mounting groove formed in the frame can be easily and firmly performed without causing a defective appearance, and the airtight material can be removed by removing the fixing tool. The airtight material can be easily replaced.

According to the second aspect of the present invention, the protrusion provided on the fixture is pressed against or bites into the airtight material or the groove or both, whereby the airtight material can be firmly fixed to the groove.

According to the third aspect of the present invention, the rigidity of the fixture is improved, and the flange portion serves as a seat surface when hammered in by a hammer or the like, so that the fixture can be easily press-fitted. Further, when removing the fixing tool, a tool such as a screwdriver can be hooked on the flange portion for easy removal.
