Further, the side surfaces of the gate 14 and the pillar 16 and the upper surface of the sill 15 are flat so that a side rubber gasket 27 and a lower surface rubber gasket 37 described later are in close contact.

[0008] In the top of the transom 11 of the door lintel 14, out
Two rows of upper row inclined about 45 degrees to the opposite side of entrance 13
Le 24 is provided, <br/> groove portion 2 6 is provided at the closed position of the upper rail 24. On the upper rail 24, left and right suspension wheels 23, 23 attached to the suspension frame 22 are rollably mounted, respectively, and the anti-sway rollers 25
The sliding door 10 is suspended from the lower end of the suspension frame 22. A motor 38 is housed and fixed inside the blind stitch 11, and pulleys 39 are attached to both left and right ends. A toothed belt 40 stretched over the pulley 39 is connected to the suspension frame 22. ing.

The sliding door 10 has an upper frame 17 at an upper end of a door plate 21, a vertical frame 18 on both sides, and a lower frame 19 at a lower end.
Are fitted with door plate fitting grooves 31, respectively. The door plate 21, the upper frame 17, the upright frame 18, and the lower frame 19 constituting the sliding door 10 are made of a material having a soundproofing effect and an electromagnetic wave shielding effect such as a metal material. On the sides of the upper frame 17 and the vertical frame 18, the narrow groove 3 is formed on the surface facing the Kamoi 14 and the pillar 16.
3 and a gasket fitting groove 32 extending to both sides is provided in the inside.

A side rubber gasket 27 is fitted into the narrow groove 33 and the gasket fitting groove 32 of the upper frame 17 and the vertical frames 18 on both sides. In the rubber gasket 27 for the side surface, two rows of hollow pressure contact portions 28 are integrally molded on one side surface, and a locking piece 29 is integrally molded on the other side surface, and a conductive coating 34 is provided on the outer peripheral surface. Have been. As shown in FIG. 3, the conductive coating 34 is formed on the surface of the chemical fiber by copper,
It is made of a woven fabric of flexible metalized fiber coated with one or several kinds of conductive metals such as nickel and carbon black by electroless plating or the like, and is adhered to the rubber gasket 27 for the side surface. Further, as shown in FIG. 5, the conductive film 34 is not a woven fabric, and one or several types of conductive metals such as copper, nickel, and carbon black are applied directly to the surface of the side rubber gasket 27 by electroless plating or the like. May be done. The side rubber gasket 27 having the conductive film 34 formed on such a surface is press-fitted and fixed to the gasket fitting groove 32 from the narrow groove 33 of the upper frame 17 and the vertical frame 18.

On the lower surface of the lower frame 19, a channel material 3 is provided.
5, a rubber gasket 37 for the lower surface is fitted. The lower surface rubber gasket 37 is
A row of hollow pressure contact portions 28 is integrally formed with a locking piece portion 29 on the upper side, and a conductive coating 34 made of a metallized fiber fabric having the same flexibility as described above, as shown in FIG.
Is adhered to the rubber gasket 27 for the side surface, or as shown in FIG. 6, a conductive film such as electroless plating of a conductive metal is applied. The rubber gasket 37 for the lower surface having the conductive film 34 formed on such a surface is sandwiched between the lower frame 19 and the channel material 35, and is prevented from coming off by the retaining projection 36.

The operation of the above configuration will be described.
In the state where the sliding door 10 is open, as shown in FIGS. 8 and 9, since the hanging wheels 23 on both sides are riding on the horizontal portion of the upper rail 24, the sliding door 10 rises slightly more than the threshold 15. In addition, since the upper rail 24 is inclined at about 45 degrees, the entrance 13 and the sliding door 10 are slightly separated from each other, and therefore, the cavity of the rubber gasket 27 for the side surface and the rubber gasket 37 for the lower surface are provided. The press-contact portion 28 includes the Kamoi 14, the pillar 16, the threshold 1
5 is opened and closed by sliding while being guided by the guide rollers 30 on the threshold 15 with a small gap between the sliding door 5 and the sliding door 5.

When the sliding door 10 is moved in the closing direction and reaches a distance P from the completely closed position, the two hanging wheels 23 which have rolled on the horizontal portion of the upper rail 24 until now have a groove 26. Depressed. When the sliding door 10 is lowered by the depth of the groove 26, the lower end of the sliding door 10 is lowered, and the rubber gasket 37 for the lower surface is lowered.
Is pressed against the upper surface of the threshold 15 and slightly crushed. At the same time, since the upper rail 24 is inclined at about 45 degrees, the groove 26 is also inclined.
As a result, the hollow pressure contact portion 28 of the side rubber gasket 27 in the upper frame 17 and the vertical frame 18 is pressed down against the side surfaces of the Kamoi 14 and the pillar 16 and slightly crushed.

As a result, the sliding door 10 includes the door plate 21, the upper frame 17, the vertical frame 18, the lower frame 19, and the conductive film 34.
Is electrically connected to the entrance / exit 13 via the connector and dropped to the ground, and the cavity pressure contact portions 28 of the side rubber gasket 27 and the lower surface rubber gasket 37 are crushed by the entrance / exit 13 so as to be in close contact. It is cut off, and the electromagnetic wave shielding effect and the soundproofing effect are obtained at the same time.

[0015]

According to the present invention, the sliding door 10 and the doorway 13 are made of a soundproof and electromagnetic shielding material, and the conductive coating 34 is formed on the rubber gasket 27. An electromagnetic wave shielding effect can be provided only by adding a simple configuration.
In addition, two rows of blanks are provided on one side of the side rubber gasket 27.
A sinus pressure contact portion 28 is provided, and a rubber gasket 37 for the lower surface is provided.
Are provided with two rows of hollow pressure- contacting portions 28 on the lower side, so that the entrance 13 has excellent adhesion to the gate 14, the pillar 16 and the threshold 15 .
