DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof sash in which a sliding door on the indoor side can be inserted and removed, and the sliding door is pulled back from the closed position to the indoor side to improve the adhesion with the airtight material. The present invention relates to a drawer for a shoji in a soundproof sash for internal and external use.

[0002]

2. Description of the Related Art A soundproof sash in which shojis are housed in a sliding manner is such that when the shojis are closed, each shoji comes into close contact with the airtight material laid on the horizontal frame and the vertical frame.
Soundproofing performance and watertightness are ensured by the sealing frame of one of the sliding doors being in close contact with the sealing material laid on the sliding door of one of the sliding doors. Since it is necessary to avoid the both sashes in the open position, they are located closer to the outside of the airtight material than they are in close contact with each other.

[0003] The attraction of the shoji is more advantageous as the distance between the open shoji and the airtight material is smaller. However, when the shojis approach each other, one of the shojis comes into contact with the other shoji and co-pulling occurs. It is necessary to keep a certain distance between the sliding doors in the expected direction because it becomes easier.To ensure airtightness at the time of closing while performing opening and closing operations without hindrance, there is not enough co-pulling between the sliding doors It is required to increase the amount of pulling at the time of closing while maintaining the interval.

[0004] In Japanese Patent Publication No. 2-48718, the amount of pulling is increased by using a gremone tablet that allows the lock to enter and exit from the upper and lower frames by rotating the handle. However, the gremone tablet has a complicated structure, so the size of the shoji increases. In order to perform pulling, a complicated mechanism must be used, such as arranging members interlocking with the handle around the inside of the frame.

The present invention has been made in view of such a background, and it is an object of the present invention to propose an apparatus which has a simple structure and performs pulling while preventing co-pulling.

[0006]

According to the present invention, a sliding block and a sliding block on the side of the door are fixed to each of the sliding frames of the inner sliding door and the outer sliding door, respectively. The rail-side pulling piece and the vertical frame-side pulling piece that are in contact with the mating-side sliding block and the door-side sliding block, respectively, are fixed to the rail and vertical frame at the position corresponding to each sliding block. A hook pulling piece that contacts the hook of the inner sliding door is fixed to the sliding door of the sliding door, and at least one of a sliding block and a pulling strip and a pulling hook and a hook that contact each other. On the other hand, with the sliding of the sliding door to the closed side, each pulling piece is inclined to push the sliding block or hook toward the indoor side, but it has a simple structure, but prevents co-pulling during opening and closing operation The shoji is drawn into the room until it reaches the closed position. .

The sliding block on the mating side is fixed to the rail side of the upper frame and the lower frame, and contacts at least the indoor side surface of the rail to regulate the out-of-plane movement of the shoji during the opening / closing operation. The rail-side pulling piece that contacts the sliding block on the mating side is fixed to the indoor side surface of the rail at the position corresponding to the mating frame when the sliding door is closed, and is attached to the sliding block on the sliding side while the sliding door is closed. Contact.

The sliding block on the door end side is fixed to the vertical frame side,
The vertical frame-side pulling piece that contacts the door-side sliding block protrudes from the surface of the vertical frame on the side of the sliding door at a position corresponding to the door frame when the sliding door is closed. Contact the side sliding block.

The hook piece attracting piece is fixed to the indoor side of the outer sliding door frame, and when the door-side sliding block comes into contact with the vertical frame side attracting piece, the inner side of the inner sliding door hanging frame is closed. Contact the hook formed on the

[0010] At least one of the contact surface of the sliding block on the mating side and the contact surface of the pulling piece on the rail side, and the contact surface of the sliding block on the doorside side and the contact face on the vertical frame side. And at least one of the contact surface of the hook piece pulling piece and the contact surface of the hook piece is inclined from the outdoor side to the indoor side from the open position to the closed position of the shoji.

As a result of this inclination, the shoji moves from the open position to the closed position, the sliding block on the mating side contacts the pulling piece on the rail side, and the sliding block on the door end side contacts the pulling piece on the vertical frame side. When the rail-side pulling piece and the vertical frame-side pulling piece are pushed toward the indoor side, the shoji is drawn indoors, and the close contact between the shoji and the airtight material is ensured.

When the inner and outer sashes are in the open position, the distance between the sliding block on the side of the door and the piece on the vertical frame side is determined by the distance between the sliding block on the mating side and the piece on the rail side. When the inner and outer shojis move from the open position to the closed position when the distance between the hook piece and the hook piece is large, first pull the sliding block on the mating side and the rail side. After the pieces come into contact with each other, the door end side sliding block and the vertical frame side drawing piece come into contact with each other. The hook piece of the outer sliding door and the hook piece of the inner sliding door come into contact at the same time when the sliding block on the door end side and the vertical frame side pulling piece come into contact with each other, and the outer sliding door moves indoors at the final pulling. Translate in parallel.

When the sliding block is brought into contact with the sliding block on the mating side and the pulling piece on the rail side, the sliding door moves toward the indoor side by an amount of the projecting piece from the rail toward the indoor side from the rail. Due to the contact between the moving block and the vertical frame-side attracting piece, the contact surface of the vertical frame-side attracting piece moves toward the indoor side by a distance in the expected direction, and both the inner sash and the outer sash are attracted in two stages.

The contact between the sliding block on the mating side and the pulling piece on the rail side and the contact between the sliding block on the door end side and the pulling piece on the vertical frame side are independent, so that the inner and outer shojis can be assembled. The distance corresponding to the sum of the distance drawn when the mating side sliding block contacts the rail side drawing piece and the distance drawn when the doorside side sliding block contacts the vertical frame side drawing piece is closed. Since it moves from the position to the indoor side, the amount of pulling the shoji is increased.

By increasing the amount of pulling of the shoji, it is possible to maintain a sufficient space between each shoji and the airtight material when the shutter is opened and between the two shojis when the door is opened and closed. Co-pulling is prevented.

In particular, with regard to the shoji, after contact between the sliding block on the mating side and the pulling piece on the rail side, the contact between the sliding block on the door end side and the pulling piece on the vertical frame side, and the hook piece pulling piece, Since the contact with the hooks occurs at the same time, the door frame and the mating frame are evenly drawn to the indoor side, and the airtightness between the door frame and the vertical frame, and the mating frame and the inner sliding door are formed. Ensuring airtightness with the mating frame is ensured.
