Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight structure for a sliding door.

[0002]

2. Description of the Related Art Conventionally, as an airtight structure of a sliding door, for example, in a gap closing device for a sliding door, which comprises a door roller rail attached to a groove of a sill or the like and an obturator attached to a lower end surface of the sliding door, the door rail has a substantially sectional shape. A door groove is provided in the center and receiving grooves are provided on both sides of the door groove, and the obturator has two protrusions that are inserted into the receiving groove, respectively, and between the lower end surface of the sliding door and the upper surface of the sill. There is known an airtight structure of a sliding door that seals the generated gap (see Japanese Utility Model Laid-Open No. 5-77490).

[0003]

However, in the above structure, since the obturator is provided only on the lower end surface of the sliding door, the gap between the lower end surface of the sliding door and the upper surface of the sill can be sealed. However, there is a problem that the gaps formed in the door contact portion, the kamoi portion, and the door pocket portion cannot be hermetically sealed.

Further, when the sealing material is always in contact with the sliding door when opening and closing the sliding door, problems such as damage of the sheet material due to rubbing and increase of opening / closing resistance of the sliding door due to frictional resistance of the sealing material occur. .

The present invention has been made in view of the above problems, and provides an airtight structure for a sliding door which can hermetically seal an opening such as a wall when closing the door, which can be opened and closed easily and the sealing material can be prevented from being damaged. The purpose is to provide.

[0006]

An airtight structure for a sliding door according to the present invention is an airtight structure for a sliding door capable of airtightly sealing an opening such as a wall, the upper and lower edges of a front portion of the sliding door, and a door closing member. Occasionally, the upper and lower edges of the sliding door are in contact with the duck and sill portions of the opening, which are formed at an angle of approximately the same gradient with respect to the reciprocating direction of the sliding door. It is characterized in that a sealing material is provided.

In the airtight structure of the sliding door according to the present invention, examples of the sealing material include elastic airtight materials having a cushioning property such as synthetic resin and rubber.

The sealing material is not the peripheral edge of the opening but
It may be provided on the peripheral portion of the sliding door. Further, if the structure is such that the edge of the sliding door is sandwiched by the sealing material when the door is fastened, it can serve as a cushioning material for hitting the door from the side and prevent the door from opening without permission. Further, the sealing material may be provided so as to wrap around the upper and lower sides of the sliding door.

[0009]

In the airtight structure of the sliding door of the present invention, the sealing material is provided at the peripheral edge of the opening which the sliding door comes into contact with when closing the door. Therefore, all the gaps formed around the sliding door when closing the door are airtightly sealed.

Further, the upper and lower edges of the front portion of the sliding door and the duck and sill portions of the opening where the upper and lower edges of the sliding door come into contact with each other at the time of closing the door have substantially the same gradient with respect to the reciprocating direction of the sliding door. Since it is formed obliquely, when the sliding door is opened and closed, a gap is formed between the sliding door and the duck and sill portions of the opening, and the sliding door is opened and closed. Accordingly, when the sliding door is opened and closed, the sheet material provided on the peripheral portion of the opening is not rubbed by the sliding door, and damage to the sheet is prevented. Further, since the opening / closing resistance of the sliding door is reduced, opening / closing of the sliding door is facilitated.
