In addition, the shutter curtain 101 wound in the shutter case has a problem that a rolling sound (contact sound) is generated between the overlapping slat 101A and the connection portion 101B at the time of winding and rewinding.

The present invention has been made on the basis of the above circumstances, and has an auxiliary function of maintaining a silencing effect of a silencing zone provided between a guide rail and a shutter curtain.
Moreover, it is an object of the present invention to provide a shutter curtain structure capable of preventing generation of a contact sound between a slat and a connection portion thereof when winding and rewinding the shutter curtain.

[0006]

Therefore, in the present invention,
As is apparent from the illustrated embodiment, the silencing band 4 is provided in the sliding groove 1A of the guide rail 1, and the impact sound between the guide rail and the shutter curtain when the shutter curtain 3 slides. In the structure of the shutter curtain in which the shutter curtain is turned off, the shutter curtain 3
Is a silencing auxiliary member 5 having a sliding contact portion 5A on the back surface of the curled connection portion 3B between the slats 3A constituting the slat 3A.
The pivotal support portion 5B having a C-shaped cross-section is externally fitted and pivotably pivoted, and at least the sliding contact portion 5A is brought into surface contact with the silencing band 4.

Further, in the shutter curtain structure of the present invention, the structure of the noise reduction auxiliary member 5 is such that the sliding contact portion 5A for contacting the noise reduction band 4 is formed of a hard material, and the sliding contact portion 5A is formed. And the connecting portion 3B of the slat 3A
It is characterized in that a buffer portion made of a soft elastic material and a pivot portion 5 pivotally attached to the back surface are formed in layers.

[0008]

[Function] Therefore, when opening and closing the shutter curtain,
The contact between the sound deadening band 4 and the shutter curtain 3 is made via the sound deadening auxiliary member 5, and as described above, the surface contact with the sound deadening band allows the sound deadening band 4 to be brought into contact with a sufficient elastic holding force. Since the shutter curtain 3 is brought into contact with the shutter curtain 3, the silencing effect can be sufficiently exhibited. In addition, when the shutter curtain is wound or unwound in the shutter case, the silencing auxiliary member prevents direct contact between the slat and the connection portion, and exhibits a buffering effect, thereby preventing generation of rattling noise. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a guide rail attached to a building frame (not shown), and guides both sides of a shutter curtain 3 drawn out of a shutter case 2 into a sliding groove (guide groove) 1A. are doing.

In the sliding groove 1A of the guide rail 1, a dovetail groove 1B as shown in FIG. 2 is formed facing the guide surface of the shutter curtain 3. In order to suppress an impact sound between the guide rail 1 and the shutter curtain 3 when the shutter curtain 3 slides, a part of a silence band 4 is attached to the dovetail groove 1B.

In this embodiment, the muffling band 4 comprises a band-like base 4A mounted in the dovetail groove 1B and a mohair 4B raised thereon, and the mohair 4B slides the shutter curtain 3. The surface is supported via the silencing auxiliary member 5 according to the present invention.

The silencing auxiliary member 5 is provided with a sliding contact portion 5A so that the back surface is in surface contact with the silencing band 4, and the slats 3A constituting the shutter curtain 3 and the mutual curled connection portions 3B of the slats 3A. On the back, at least the silence band 4
, I.e., near the left and right ends of the slat 3A, pivotally support the C-shaped cross-section 5B.

In this embodiment, as shown in FIG. 3, the silencing auxiliary member 5 includes, for example, a sliding contact portion 5A made of hard vinyl chloride and serving as a back surface, and a sliding contact portion 5A.
A cushioning portion 5C made of soft vinyl chloride having elasticity is integrally formed in a layer shape between a pivot portion 5B made of the same hard vinyl chloride as that of A, and a C-shaped cross section. Are connected to each other via the fixed part 6.

Therefore, when the shutter curtain 3 is opened and closed, the silencer 4 does not directly contact the sliding surface of the shutter curtain 3 side, that is, the back surface of the connecting portion 3B of the slat 3A. Since the mohair 4B is elastically supported via the contact portion 5A, the mohair 4B and the sliding contact portion 5A are in surface contact, and the mohair 4B can exhibit a sufficient elasticity retaining force.

In addition, when the shutter silencing auxiliary member 5 is wound or unwound, the slats 3 can be used even when the shutter curtain 3 is wound inside or outside as shown in FIG.
Since the contact between A and the connection portion 3B is made via the noise reduction auxiliary member 5, it is possible to prevent the generation of a contact sound such as a squeak sound in the shutter case 2.

In the above-described embodiment, the noise reduction auxiliary member 5 is used.
In addition, since the buffer portion 5C made of soft vinyl chloride is provided, it is possible to maintain some flexibility, which is more advantageous in eliminating impact noise and wind impact noise.

The auxiliary member 5 may be provided in an elongated shape over the width and the entire length of the slat 3A, or may be provided partially at a plurality of positions. In this case, the slats 3A of the shutter curtain 3 wound in the shutter case 2 do not directly contact each other, and the painted surface of the slat 3A is not damaged. The auxiliary member 5 may be provided at least at a position corresponding to the muffling band 4.

[0018]

According to the present invention, as described in detail above, a silence band is provided in the slide groove of the guide rail to reduce the impact sound between the guide rail and the shutter curtain when the shutter curtain slides. In the shutter structure, the shutter curtain is configured such that the shutter curtain pivotally pivots a noise-suppression auxiliary member having a sliding contact portion on a back surface of a connection portion of a slat constituting the shutter curtain. Since the surface contact is made correspondingly, when the shutter curtain is blown by external force such as wind, it does not generate an impact sound between the shutter curtain and the guide rail, and the painted part of the slat surface Does not peel off. And, without making the mohair of the silence band wear, the auxiliary effect of maintaining the silencing effect of this silence band is made,
In addition, when the shutter curtain is wound or unwound, the effect of preventing the generation of a contact sound such as a squeaking sound between the slat and the connection portion can be obtained.

Further, by forming a buffer portion on the noise-reduction assisting member, it is possible to further prevent the generation of impact noise, contact noise, and the like.
