DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof sash for pulling out a sliding door and closing the sliding door, such as a sliding door, a sliding door, and the like, so as to increase the adhesion with a sealing material to thereby prevent sound in the room.

[0002]

2. Description of the Related Art In a sliding shoji, after closing an indoor shoji and an outdoor shoji, a crescent (drawing fitting) is used.
There is known a soundproof sash in which both are pulled toward each other and pressed, and both shojis are pressed against a sealing material provided on a frame to enhance hermeticity and thereby provide soundproofing in a room. In such a soundproof sash, for example, Japanese Utility Model 3-49024
As disclosed in Japanese Unexamined Patent Publication (Kokai) No. H07-163, a sealing material (airtight block) is provided in a vertical frame of a sash frame, in a concave portion for receiving a door frame of a closed shoji screen, in contact with a side surface of the door frame to achieve airtightness. When the crescent fitting is locked, the shoji is drawn to the concave side wall of the sash frame, and the sealing material is pressed against the door frame.

[0003]

However, in the pulling apparatus disclosed in the above-mentioned publication, the soundproofing effect can be achieved by tightening the shoji with the crescent metal fittings, but the crescent when opening the shoji is required. Even if you loosen the bracket, the shoji will be in close contact with the sealing material, and after unlocking the crescent bracket, it will require force to remove the sealing material when pulling and opening the shoji, making it difficult to open the shoji. There is a point.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and has as its object to provide a soundproof sash capable of easily opening and closing a shoji by releasing the close contact of a sealing material after releasing a pull-in fitting. And

[0005]

In order to achieve the above object, the present invention according to claim 1 is provided with a sash frame, a shoji that can run in the sash frame and a door frame of the shoji. A recess provided in the vertical frame of the sash frame to receive the protrusion when the shoji is closed, a seal provided in the recess and abutting against the door frame when the shoji is closed, and a sealing material for closing the shoji when the shoji is closed Side, and a pulling tool that presses the protrusion of the sash (shoji) and the sealing material against each other.The sealing material includes a pressing contact portion that is positioned obliquely from the side wall forming the concave portion to the bottom wall .
The side that can receive the protrusion forms an open angle, and the protrusion
The part has a tapered angle, which is different from the opening angle of the sealing material.
The angle of the protruding portion is larger, and when the shoji is drawn by the pulling tool, the pressing portion is pressed by the protruding portion and is elastically deformed.

According to the first aspect of the present invention, when closing the sliding door in the sash frame, the door frame of the shoji is brought into contact with the vertical frame of the sash frame to close the window. At this time, the projection of the door frame fits into the recess of the vertical frame, and then, when the sliding door is locked to draw the shoji to the sash frame, the projection of the door frame becomes
It is drawn to the side wall side of the concave portion, and presses the press-contact portion of the seal material to elastically deform. On the other hand, when the pulling fitting is released, the press-contact portion is elastically restored, and the projection is pushed back by the elastic restoring force, whereby the close contact of the sealing material between the door frame and the vertical frame is released. Therefore, when the shoji is opened after the pull-in fitting is released, there is almost no sticking of the sealing material, so that no force is required for opening and closing the shoji and the window can be easily opened. Also, the angle of the projection is better than the opening angle of the sealing material.
The projections should press the sealing material sufficiently.
The elastic deformation can be large and sufficient
it can. Therefore, when the pulling bracket is released,
Return can be large.

According to a second aspect of the present invention, in the first aspect of the present invention, the base member is attached to the side wall of the concave portion, and the distal end portion is located on the bottom wall. A pressure contact portion is formed between the pressure contact portion and the space, and a space is formed on the back surface of the pressure contact portion.

According to the second aspect of the present invention, since the seal member is arranged so as to form a space behind the press contact portion, the press contact portion of the seal material can be largely elastically deformed by utilizing the space. After the release fitting is released, the push-back of the protrusion by elastic return can be increased, and the close contact of the sealing material can be easily released.

According to a third aspect of the present invention, in the second aspect of the present invention, the seal member is a block having a substantially triangular cross section from the side wall to the bottom wall of the recess, and the space of the press contact portion is formed by the seal member. It is characterized by being formed hollow.

According to the third aspect of the present invention, since the seal member is a block having a substantially triangular cross section, it can be easily installed in the concave portion.
