Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide rail structure for a shutter curtain, and more particularly, to a guide rail and a shutter curtain which are located in a guide groove of the shutter curtain in a sliding groove of the guide rail when the shutter curtain slides. The guide rail structure of the shutter curtain is equipped with a sound deadening band to eliminate the impact sound between the two.

[0002]

[Prior art]

 Conventional shutter curtains have a sound deadening band that has a substantially tubular structure that uses a material that slides well against frictional sliding, such as hard vinyl chloride, or a structure that has mohair raised on a band-shaped base. By fixing this muffling band to the mounting groove formed inside the sliding groove of the aluminum or steel guide rail, the impact between the guide rail and the shutter curtain when the shutter curtain moves up and down. It works to turn off the sound.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional sound deadening band is fixed by caulking a predetermined part of the mounting groove formed on the guide rail in order to prevent it from moving in the opening and closing direction by making sliding contact when opening and closing the shutter curtain. Or, it is fixed by means such as adhesion.

Therefore, in the process of repeating the opening and closing of the shutter curtain, in the case of a silencing band having a mohair structure, the mohair is worn or deformed, that is, “sag” occurs, and a sufficient silencing effect is maintained. If it becomes impossible, the guide rail and the shutter slats may come into direct contact with each other, which may cause a metallic noise, so it is necessary to replace this silence band.

However, as described above, the sound deadening band is fixed in the mounting groove inside the guide rail, and in order to replace this sound deadening band, the guide rail must be removed from the building frame. There is a problem that it cannot be easily replaced.

Therefore, the present invention has been made based on the above-mentioned circumstances, and it is easy to replace a deadening band caused by wear or the like, even if the guide rail is fixed to the building frame, in that state. The purpose is to provide an improved shutter curtain guide rail structure that can be replaced.

[0007]

The sliding surface of the shutter curtain 3 on the open side 1d of the moving groove 1a is projected over substantially the entire length of the guide rail main body 1, and the rear side 1e of the sliding groove 1a is extended to the long side ( 6) a pair of long and short locking claws 6, 7, and a short claw 10 that engages the long locking claw 6 of the pair of long and short locking claws 6, 7 and a short locking claw 7 With long nail 11 The long and short claws 10 and 11 are connected to each other by a flexible contact portion 12, and a sound deadening band 13 having a substantially U-shaped cross section is provided.

Further, a curved concave portion 14 may be formed in the contact portion 12 connecting the long claw 11 and the short claw 10 of the muffling band 13.

[0009]

[Action]

 When the sound deadening band 13 deteriorates in function due to wear and needs to be replaced, with the shutter curtain 3 open, the long claw 11 of the sound deadening band 13 is pulled out from the short locking claw 7. When the engagement between the short claw 10 and the long engagement claw 6 is released in the inward direction 1e of the sliding groove 1a with the engagement position of the short claw 10 and the long engagement claw 6 as the center of rotation, the sound is silenced from the engagement claws 6, 7. Since the band 13 is removed, it can be taken out from the opening 1d side of the sliding groove 1a. Also, when the muffling band 13 is attached to the guide rail 1 side, the short claw 10 is located at the inner side of the sliding groove 1a. The long pawl 11 is elastically restored by the elastic locking force of the long pawl 11 of FIG. Is engaged with the short locking claws 7 and is engaged with and attached to the respective locking claws 6, 7.

Further, by forming the curved concave portion 14 in the contact portion 12 of the sound deadening band 13, the flexibility is increased in the concave portion 14, and the attachment and detachment on the guide rail 1 side becomes easy. .
