[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lower frame of a horizontal sliding shoji to which an airtight material that abuts a rail side surface of a lower frame supporting a door roller is attached, The present invention relates to a lower frame structure of a laterally-pulling shoji, which has a simple structure that can be easily replaced and has an anti-flaking effect.

[Conventional technology]

In general, a door frame supported by a rail projecting on the lower frame is attached to the lower frame of the horizontal sliding shoji, and is brought into contact with the lower frame for airtightness and rain finish. Airtight material is attached.

As the airtight material attached to the lower frame of the horizontal sliding shoji, there is one in which the tip of the airtight material is in contact with the upper surface of the lower frame or the stepped outer surface, but it has an improved appearance and exists on the lower frame. For the purpose of preventing damage due to contact with foreign matter, etc., and preventing damage and deterioration due to being always exposed to the outside of the lower frame, it is attached to the inner surface of the lower part of the lower frame and its tip touches the side surface of the rail of the lower frame. It is getting closer to me.

[Problems to be solved by the invention]

In the lower frame of such a horizontal sliding door, the airtight member that is brought into contact with the side surface of the rail has a T-shaped cross section, and the rail contact portion of the airtight member is located on the rail side at the lower inner side surface of the lower frame. The base is inserted into the airtight material mounting part that has an opening groove (usually a lip groove) with a width that can be projected, and the side opposite to the rail from the opening groove forms a space part wider than the width of the opening groove. The rail abutting part has a structure that is attached to the lower frame so that it projects from the opening groove.Beside this airtight material, there is a door roller equipped with tires that run on the rail, so replace the door roller. Then, there is a problem that the door roller cannot be removed without removing the airtight material, and when trying to remove the airtight material, the airtight material is attached over the entire length of the lower frame, so the vertical frame Must be removed It is not possible to remove the fine material problem that can not be performed easily removable airtight material has been made.

[Means for solving problems]

As a result of earnest research to solve this problem, the present inventor found that
An opening groove with a width that allows the rail contact part of the airtight material to protrude to the rail side is provided on the lower part of the inner side surface of the lower frame, and a space part wider than the width of the opening groove is formed on the opposite side of the opening groove from the rail. The airtight material mounting part is provided, and the base of the airtight material is inserted from the end of the lower frame along the airtight material mounting part to stop the structure for mounting the airtight material, making the cross section of the airtight material L-shaped and The lower frame of the shoji does not lock the upper and lower parts of the airtight material on the inner surface of the lower part, but supports only the lower end of the airtight material by the receiving part and prevents the falling of the airtight material, and simply abuts the lower frame contact part. The structure is only provided with the airtight material abutting part, and this airtight material is positioned from the door frame side of the lower frame so that the lower frame abutting part abuts on the airtight material abutting part, and the lower frame rail is placed on the lower surface. It has a groove to straddle, and the lower frame contact part of the airtight material is pressed against the airtight material contact part of the lower frame on the side surface to fix it. If you attach the anti-floating and airtight material stopper that has a protruding part to the lower surface of the lower frame at a predetermined position where there is no door roller by screwing from below, the above-mentioned anti-floating and airtight material can be used when replacing the airtight material. The airtight material can be easily removed from the lower frame by removing it from the lower frame by removing the screw that attaches the material stopper to the lower frame.
Also, when replacing the door roller, if the airtight material is removed by the above operation, the airtight material will not interfere with the removal and installation of the door roller. The inventors of the present invention have completed the present invention by discovering that the concave groove portion that straddles the rail also has the anti-sway effect of the horizontal sliding door, and that it can be a very excellent horizontal sliding door.

That is, according to the present invention, in a lower frame of a horizontal sliding door having an airtight member attached to the side surface of a rail of a lower frame for supporting a door roller, the airtight member does not lock at least an upper portion and has a receiving portion at a lower portion. It has a L-shaped cross-section consisting of a lower frame contact portion which is brought into contact with the lower inner surface of the lower frame and a rail contact portion which is brought into contact with the side surface of the rail of the lower frame, and which crosses the rail on the lower surface. An airtight material stopper having a recessed groove portion and a protrusion for pressing and fixing the lower frame contact portion of the airtight material to the inner side surface of the lower frame is provided at a predetermined position where there is no door roller of the lower frame. The present invention provides a lower frame structure of a horizontal sliding shoji characterized by being more screwed.

〔Example〕

Hereinafter, an embodiment of the lower frame structure of a horizontal sliding door according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view for explaining a lower frame structure of a horizontal sliding shoji according to the present invention, and FIG. 2 is a longitudinal sectional view of the same.

In the drawings, reference numeral 1 is a lower frame of a sash, and a rail 1a is provided at a predetermined position on the upper surface of the sash in a longitudinal direction thereof. Reference numeral 2 denotes a lower frame of a horizontal sliding door shovel to which a door roller 3 supported by a rail 1a of a lower frame 1 is attached at a predetermined position, and an airtight member is provided on at least an upper part of an inner surface of a lower part of the lower frame 2. There is provided an airtight material contact surface 2a against which the surface of the airtight material opposite to the rail is abutted without being stopped, and the airtight material contact surface 2a is provided at the lower end thereof as in the illustrated embodiment. The receiving portion 2b is provided so as to prevent it from falling. Reference numeral 4 is a cross section composed of a lower frame contact portion 4a which is brought into contact with the airtight material contact surface 2a on the lower inner surface of the lower frame 2 and a rail contact portion 4b which is brought into contact with the side surface of the rail 1a of the lower frame 1. The airtight material has an L shape. Reference numeral 5 has a concave groove portion 5a on the lower surface for straddling the rail 1a of the lower frame 1 and a side surface of the airtight member 4 having a lower frame contact portion 4a.

[Action]

In the lower frame structure of the horizontal sliding door according to the present invention composed of such constituent members, when the airtight material 4 is to be replaced, the horizontal sliding door is removed, and the screw 6 is loosened from below to prevent the anti-flaking / airtight material stopper 5. When the lower frame 2 is removed, the airtight material 4 that has been brought into contact with the airtight material contact surface 2a on the lower inner surface of the lower frame 2 is released from the pressing and fixing by the protruding portion 5b of the airtight material stopper 5 which also serves as the anti-flare member. Because it is done, it can be easily removed. When the old airtight material 4 is removed from the lower frame 2 in this way, the lower end of the lower frame contact portion 4a of the new airtight material 4 is brought into contact with the receiving portion 2b of the lower frame 2 and the lower frame contact portion 4a is moved to the lower frame. When the airtight material contacting surface 2a of the lower frame 2 is brought into contact with the lower frame 2, the anti-flaking / airtight material stopper 5 is positioned at a predetermined position on the lower inner surface of the lower frame 2 and the screw 6 is screwed from below to the lower frame. When fixed to 2, the airtight member 4 has a lower frame contact portion 4a which prevents the airtight member 5 from being frayed.
The replacement of the airtight material 4 is completed by being pressed and fixed to the airtight material contact surface 2a of the lower frame 2 by the protruding portion 5b.

When replacing the door roller 3, the airtight material 4 is used.
By removing the anti-flaking / airtight material stopper 5 and the airtight material 4 in the same manner as when replacing the door, the doortight material 4 which is an obstacle when the door roller 3 is removed from the lower frame 2 does not exist, so the door roller 3 can be easily installed. After removing and attaching a new door roller 3, the removed airtight material 4 is fixed in the same manner as the fixing of the new airtight material 4 at the time of replacement of the airtight material 4 with the airtight material stopper 5 for preventing the airtightness of the lower frame 2. It suffices to press and fix the contact surface 2a.

〔effect〕

As described above in detail, in the lower frame structure of the horizontal sliding door according to the present invention, the cross-sectional shape of the airtight material is changed from the conventional T-shape to the L-shape, and the airtight material mounted on the lower inner surface of the lower frame is mounted. The part can be inserted only from the side edge of the lower frame, and it can not be easily removed after inserting it.The conventional structure was changed so that it can be simply applied from the lower inside of the lower frame and abutted. Therefore, in order to prevent the airtight material from falling off easily, there is a push groove on the lower surface that straddles the rail of the lower frame, and the lower frame contact part of the airtight material is pressed to the inner surface of the lower frame on the side surface. It is only necessary to screw the anti-floating and airtight material stopper having the protruding portion to be fixed to the lower frame at a predetermined position where there is no door roller from below, and the lower frame has a member more than that of the conventional airtight material mounting portion. It has the advantage of saving, and the horizontal sliding screen has a lower frame. It has the advantage that it can be prevented from coming off from the roll and meandering by the anti-flipping effect of the concave groove part provided on the bottom surface of the airtight material stopper that also functions as the airtightness stopper. It has various advantages such as no need for the complicated work of removing the horizontal frame of the horizontal sliding shoji when exchanging doors and doors, and its practical value is extremely large.
