JPS6019915Y2 - Airtight material for sliding shoji at Satsushi - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an airtight material for sliding shoji in Satsushi.

Airtight materials are installed between the frame and the door frame and the door frame that require airtightness in the satsushi.

Conventional airtight materials have a structure with one or two fins protruding from the mounting part.

To explain this in detail based on FIG. 1, the mounting parts of the airtight material A made of an elastic material are attached to the mounting members 2 formed in the shape of grooves with lips at the ends of the inner and outer door front frames 1 and 1'. 3
is fixed so that it will not come off, and two straight fins 4, 4 are provided protruding from this mounting part 3, and these fins 4.4 are attached to the vertical frame 5,
It is constructed so as to be in contact with sealing pieces 6, 6, respectively, which are provided protruding from 5' toward the opening side.

Note that the same airtight material A is used for the 6 inner and outer frames.

Conventionally, because of the above-mentioned configuration, opening and closing resistance was large, especially in the connecting stile, and when the fins 4, 4 were bent into a dogleg shape in order to reduce the resistance, they would catch on the crescent holder and break. There was a drawback that

The object of the present invention is to eliminate the above-mentioned conventional drawbacks and to provide an airtight material for a sliding shoji in a sash that has reliable airtightness and no opening/closing resistance.

The structure of the present invention will be explained in detail based on the case where it is implemented on the connecting frame shown in the drawings.
', and a protruding S-shaped tri-shaped surface 9 is provided so as to form a hollow part 8 at the center side of the mounting parts 3, 3'.

This wall surface 9 is formed with a curved surface 10 on the door edge stile side (closed side), and a straight fin 4' is provided to protrude outward at the joint between the curved surface 10 and a straight outer wall surface 11.

Further, on the side wall 12 located on the opposite side of the curved surface 10 of the wall surface 9, a tape-shaped fin 4# is provided protruding outward from the side surface and shorter than the fin 4', so that when the shoji is closed, it can be used to draw a crescent or the like. Airtight material A' is placed so that it comes into contact only when the stile is pulled together using the pulling device.
Configure.

The airtight material A' configured as described above is attached to the inner 6 mating frame 13.
The mounting portions 3', 3' are fitted into the mounting grooves 14.degree.14 of the mounting member 2' provided in the mounting member 2' so as not to come off, and the fins 4' are brought into contact with the opposing outer mating frame 13'.

Incidentally, the tip of the fin 4' is formed to be longer by S so as to be located outside the contact surface of the outer joining frame 13'.

Note that 15 in the figure is a lower frame. The present invention is constructed as in the above-mentioned embodiment, and when the shoji is closed, the fins 4' contact the outer housing frame 13' and are in an inclined state, as shown by the chain lines in Fig. 2, to maintain airtightness. do.

In addition, when the crescent is closed, the inner and outer housing frames 13.1
3' is spaced narrower, and the fin 4'' is also brought into contact with the outer accommodation frame 13'.

Conversely, when opening the shoji, the fins 4' try to stand up straight as shown by the solid line.At this time, the wall surface 9 on which the fins 4' are provided is shaped with a hollow part 8 on the inside, And fin 4
Since the wall surface 9 is composed of a curved surface 10 from the protruding part of the fin 4', the fin 4' deforms the wall surface 9, dents it in the hollow part 8, stands upright, and returns to its original shape when separated from the outer accommodation frame 13'. to return to.

In the above embodiment, the airtight material attached to the connecting frame was explained, but in FIG.
The airtight material A' of the present invention may be attached in place of the airtight material A attached to '.

In some cases, the front stile of the inside and outside doors is also pulled toward the frame side by the pulling device.

Since the present invention has the above-mentioned structure and operation, the long fins 4' are tilted and drawn into the hollow part 8 when opening and closing the shoji, so the resistance is small, and the shoji can be pulled by the pulling device. Only when they are brought together, both the long and short fins 4', 4'' can reliably abut against the opposing surfaces to maintain airtightness.

Also, there is no risk of it getting caught in the crescent holder and breaking.

[Brief explanation of the drawing]

The figures show an example of an airtight material for a sliding shoji in a sash according to the present invention.
The figure is an enlarged cross-sectional plan view of the airtight material. In addition, in the figure, 1, 1' and 14, 14' are vertical stiles (inner and outer door front stile, inner and outer door opening stile), 4' is the fin, 7 is the base, 8 is the hollow part, 9 is the wall surface, and 10 is the curved part. It is a surface.

Claims (1)

[Scope of utility model registration request] A U-shaped wall surface 9 is provided protruding from the base 7 to be attached to the vertical stile, and a curved surface 10 is provided with the open side facing the shoji closing side to form a hollow portion 8. A protruding length fin 4' (from the position) is provided to protrude straight, and a short fin 4" is provided to protrude from the opposite side of the curved surface 10 of the wall surface 9 to come into contact with the opposing surface when the shoji is pulled.
