Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a structure for a shutter curtain used for shutters, garages, entrances and exits of buildings, etc. The present invention relates to an improvement in the structure of a shutter curtain that eliminates impact noise between the shutter curtain and the shutter curtain.

[0002]

[Prior art]

 In the conventional shutter, as shown in FIGS. 4 and 5, when the shutter curtain 101 slides when moving up and down, in order to eliminate the impact sound generated between the shutter curtain 101 and the guide rail 102, or when the shutter curtain 101 is closed In order to eliminate the wind noise of the shutter curtain 101 caused by the fanning, the sound deadening band 103 is provided on the inner side surface of the guide rail 102 to prevent the shutter curtain 101 and the guide rail 102 from directly colliding with each other. .

A mohair with a base is often used for the muffling band 103. The back surface of the shutter curtain 101 that comes into contact with this is the connecting portion 101B between the slats 101A that compose the mohair. In contrast, it is point contact.

[0004]

[Problems to be solved by the device]

 Therefore, when the shutter curtain 101 is agitated by an external force such as wind, the elastic holding force of the mohair cannot support the shutter curtain 101 and an impact sound is generated between the shutter curtain 101 and the guide rail 102. I will end up. When the shutter curtain 101 is opened and closed, the slat 101A moves up and down while swinging, so that the slat 101A hits the guide rail 102 and wears the mohair.

[0007] Furthermore, the coated part of each slat 101A of the shutter curtain 101 may be peeled off due to the impact during the ascending / descending, which may cause rusting. Especially in the case of a manual type shutter, when the shutter curtain 101 is opened, it is lifted up vigorously from the middle, and when it is closed, it is pulled down vigorously, so the shutter curtain 101 and the guide rail 102 There is a problem that a strong impact may be applied between the two, causing the above-mentioned impact noise, mohair wear, and rust caused by paint peeling to become remarkable.

Furthermore, since the connecting portion 101B of the slats 101A is in point contact with the mohair, the mohair hair is always in contact with the same position of the mohair when the shutter curtain 101 is closed. There is a problem in that the mohair hair remains in a collapsed state and the silencing effect is lost.

The present invention has been made based on the above circumstances, and maintains the sound deadening effect of the sound deadening band provided between the guide rail and the shutter curtain, so that the contact sound between the guide rail and the slats can be reduced. The purpose is to provide a structure for a shutter curtain that prevents the occurrence.

[0008]

[Means for Solving the Problems]

 For this reason, in the present invention, as clearly shown in the illustrated embodiment, a pair of silencer bands 4 facing each other are provided in the sliding groove 1A of the guide rail 1 to prevent the shutter curtain 3 from sliding. In the structure of the shutter curtain that eliminates the impact sound between the guide rail 1 and the shutter curtain 3, in the slat 3A that constitutes the shutter curtain 3, the front flat portion 5 and the upper end engaging portion 6 are continuously formed. In addition, an upper back flat portion 8 parallel to the front flat portion 5 and a lower end engaging portion 7 are continuously formed, and a lower back flat portion 9 parallel to the front flat portion 5 is a continuous support portion. The front flat portion 5 and the front flat portion 5, which are integrally formed by being connected by 10 and have a cross-sectional shape formed by curving a ridge portion 11 formed by adjacent portions 5, 6, 7, 8, 9, 10. Is characterized in that in correspondence with the lower rear flat portions 8 and 9 in the silencing strip 4 is made to face contact.

[0009]

[Action]

 Therefore, when the shutter curtain 3 is opened and closed, the contact between the silencer band 4 and the shutter curtain 3 is made through the flat portions 5, 8 and 9 on the front and back surfaces of the slat 3A. The surface 4 is in surface contact with the silencing band 4, and the silencing band 4 is brought into contact with the shutter curtain 3 with a sufficient elastic holding force, so that the silencing effect can be sufficiently exerted. Moreover, since the slat 3A has a rounded cross-sectional shape with the ridge 11 curved, the slat 3A moves up and down without damaging the mohair hairs 4B when the slat 3A contacts and abuts the sound deadening band 4.

[0010]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 is a guide rail attached to a building frame (not shown), and both sides of the shutter curtain 3 pulled out from the shutter case 2 are placed in the sliding groove (guide groove) 1A. I'm guiding you.

Inside the sliding groove 1A of the guide rail 1, there are formed dovetail grooves 1B facing the guide surface of the shutter curtain 3 as shown in FIG. Then, in order to eliminate the impact sound between the guide rail 1 and the shutter curtain 3 when the shutter curtain 3 slides, a muffling band 4 is partially attached to each dovetail groove 1B. There is.

In this embodiment, the sound deadening band 4 is composed of a band-shaped base 4A mounted in the dovetail groove 1B and a mohair 4B raised therein, and the facing mohairs 4B form the shutter curtain 3. Is supported through the sliding surface of.

As shown in FIG. 3, each slat 3 A that constitutes the shutter curtain 3 has a front flat portion 5 and a curl-shaped upper end engaging portion 6 which are continuously formed and is parallel to the front flat portion 5. An upper back flat portion 8 and a curl-shaped lower end engaging portion 7 are continuously formed, and a front flat portion 5 and a lower back flat portion 9 parallel to each other are connected by slanted continuous support portions 10 to be integrally formed. While being formed, each ridge portion 11 formed by the adjacent portions 5, 6, 7, 8, 9, 10 has a sectional shape formed by being curved with a predetermined curvature.

Then, the shutter curtain 3 is configured by engaging the other slats 3A with the respective engaging portions 6 and 7 at the upper end and the lower end and continuing them in the vertical direction. The upper and lower engaging portions 6 and 7 that engage and connect the respective slats 3A are located inside the upper and lower rear flat portions 8 and 9, that is, between the front flat portion 5 and the rear flat portions 8 and 9. It is like this.

Therefore, when the shutter curtain 3 is opened and closed, each slat 3A of the shutter curtain 3 moves up and down between the sound deadening zones 4 of the guide rail 1 facing each other, and the flat portions 5, 8, 9 of each slat 3A are moved. However, it comes into contact with the mohairs 4B of both silencing zones 4 and receives sufficient elastic support of the mohairs 4B. In other words, since the slats 3A are in surface contact with the mohairs 4B by the flat portions 5, 8 and 9, the mohairs 4B can exhibit a sufficient elastic holding force without being crushed.

In addition, the slat 3A has a curved ridge portion 11 formed by the respective portions 5, 6, 7, 8, 9, and 10 instead of a square shape due to bending, and therefore, the silencing band is moved when the slat 3A is moved up and down. It is possible to move smoothly without damaging the mohair 4B of No. 4, the mohair 4B does not wear, and it is possible to prevent the generation of contact noise.

[0017]

[Effect of device]

 As described in detail above, in the structure of the shutter curtain according to the present invention, the slat is formed by connecting the front flat portion and the upper end engaging portion in a continuous manner, the upper flat portion parallel to the front flat portion, and the lower end engaging portion. The joining part is formed continuously, and the front flat part and the lower back flat part parallel to each other are connected integrally by the continuous support part and are integrally formed, and the ridge part of each adjacent part is curved and formed. Since the front flat part and the upper and lower back flat parts are in surface contact with each other in correspondence with the sound deadening zone, the shutter curtain will be damaged when it is fanned by external force such as wind. No impact noise or contact noise is generated between the shutter curtain and the guide rail when moving up and down, and each slat can receive sufficient elastic support of the mohair in the sound deadening zone. The mohair with wear is reduced by the surface contact can be maintained at all times sufficient elastic holding force without or falling or being ulcers, there is an effect that the wind striking noise is reduced at the time of closing of the shutter over the curtain. Further, from this, there is an effect that the painted portion of the slat surface is not peeled off and the risk of rusting is eliminated.

Moreover, according to this slat, since the ridge part formed by each of the above-mentioned parts has a curved shape rather than a rectangular shape by bending, it can move smoothly without damaging the mohair of the muffling band when the slat moves up and down. As a result, the wear of mohair is reduced, and contact noise can be prevented.
