BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail structure of a shutter curtain, and more particularly, to a guide rail structure located in a slide groove of a guide rail and located on a guide surface of a shutter curtain.
TECHNICAL FIELD The present invention relates to a guide rail structure of a shutter curtain provided with a sound deadening band for suppressing an impact sound between the guide rail and the shutter curtain when the shutter curtain slides.

[0002]

2. Description of the Related Art The sound deadening band of a conventional shutter curtain employs a structure in which mohair is raised on a band-shaped base. The base of the sound deadening band is formed by sliding grooves of guide rails made of aluminum or steel. It is fixed to the mounting groove etc. formed inside, and when sliding the shutter curtain,
The mohair works to eliminate the impact sound between the guide rail and the shutter curtain.

[0003]

However, the above-described conventional silence belt is formed on a guide rail so as not to move in the opening / closing direction by sliding contact when the shutter curtain is opened / closed. A predetermined portion of the mounting groove is fixed by caulking, or is fixed by means such as bonding. For this reason, in the process of repeatedly opening and closing the shutter curtain, when the mohair is worn or the mohair deforms, that is, causes `` set '', and it is not possible to maintain a sufficient noise reduction effect, it is necessary to replace the noise reduction band. is there.
However, as described above, the sound deadening zone is fixed inside the guide rail, and for replacement of the sound deadening zone, the guide rail must be removed from the building frame, and the sound deadening zone cannot be easily replaced. There is a defect.

The present invention has been made on the basis of the above circumstances, and it is possible to replace a noise-reducing band caused by wear or the like while the guide rail is fixed to the building frame. It is an object of the present invention to provide an improved shutter curtain guide rail structure.

[0005]

For this reason, the guide rail structure of the shutter curtain of the present invention has a sliding groove 1A of the guide rail, as is apparent from the illustrated embodiment.
And a guide rail of a shutter curtain provided with a sound deadening zone 5 for suppressing an impact sound between the guide rail and the shutter curtain 3 at the time of sliding of the shutter curtain. In the structure, a dovetail groove 4A is opposed to a sliding surface of the shutter curtain 3 on a guide rail main body 1 having a channel-shaped cross section having a sliding groove 1A and an open side of the sliding groove 1A of the guide rail main body 1. And a band-shaped base 5A is removably inserted into a dovetail groove 4A formed in the band-shaped mounting member 4, and the band-shaped mounting member 4 is fixed to the band-shaped mounting member 4. And a muffling band 5 fixed between the screws 6 for fixing the muffler to the guide rail main body 1.

[0006]

Accordingly, the silencer 5 is, for example, the mohair 5B
In the case where the function is deteriorated due to the "set" and the need for replacement occurs, the screw 6 is removed with the shutter curtain 3 opened, and the muffling band 5 is opened together with the band-shaped mounting member 4 to open the sliding groove 1A. Can be taken out from the section, and the replacement of the muffling band 5 becomes easy. Moreover, with the above screw function,
The sliding direction of the sound deadening band 5 with respect to the band-shaped mounting member 4 can also be fixed, and the sound deadening band 5 with respect to the mounting member 4 can be replaced by caulking the guide rail 1 side or using an adhesive as in the related art. In comparison, it becomes simple.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on the illustrated embodiment. In the drawing, reference numeral 1 denotes a guide rail body 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. doing.

As shown in FIG. 2, the guide rail main body 1 has mounting edges 1B on both sides of the opening of the sliding groove 1A.
1B, a band-shaped mounting member 4 having a dovetail groove 4A is arranged inside the guide rail 1 and mounted on the guide rail main body 1 by means of screws 6. . The screws 6 for fixing the belt-shaped mounting member 4 to the guide rail 1 are located at least at both upper and lower ends of the mounting member 4 and are fixed.

As shown in FIG. 3, the band-shaped mounting member 4 has a muffling band 5 in which a mohair 5B is implanted in a band-shaped base 5A, with the band-shaped base 5A being fitted into the dovetail groove 4A. , Is installed. As shown in FIG. 4, the sound deadening band 5 is mounted between screws 6 for fixing the mounting member 4 to the guide rail 1.

The tip of the mohair 5B of the sound deadening band 5 extends inward from the opening of the dovetail groove 4A into the guide rail 1, and elastically contacts and slides on the front and rear surfaces of the shutter curtain 3 as shown in FIG. It is supposed to be.

Therefore, when the silencing band 5 is deteriorated due to, for example, "moistening" or wear of the mohair 5B and needs to be replaced, the screw 6 is removed with the shutter curtain opened. Along with the band-shaped mounting member 4, a muffling band 5
Can be taken out from the open portion of the sliding groove 1A, so that the muffler band 5 can be easily replaced.

In the above embodiment, when the band-shaped mounting member 4 is mounted on the guide rail main body 1 by means of the screw 6 at a predetermined position in the longitudinal direction of the band-shaped base 5A of the sound deadening band 5, Since it is configured to be fixed to the band-shaped mounting member 4, the mounting and dismounting can be easily performed without particularly requiring screwing of the muffling band 5. Also,
Inexpensive replacement means such as using an adhesive for fixing do not have to be adopted.

[0013]

[Effects of the Invention] The present invention has been described in detail above. The present invention is located in the guide groove of the shutter curtain in the slide groove of the guide rail. In the guide rail structure of the shutter curtain equipped with a sound deadening band for suppressing the impact sound between the guide rail, the guide rail is provided with a channel type cross-section guide rail body and the above-mentioned sound deadening band on the shutter curtain sliding surface. It is composed of a band-shaped mounting member to be opposed, and the band-shaped mounting member is screwed to the guide rail on the open side of the sliding groove, so that the muffler band for the guide rail is exchanged, and the guide rail is fixed to the building side. In this case, a practical effect is obtained that the replacement can be executed in that state.

The band-shaped base of the sound deadening band is fixed to the band-shaped mounting member at the same time when the band-shaped mounting member is mounted on the guide rail main body by means of a screw at a predetermined position in the longitudinal direction. With such a configuration, there is no need for a fixing means such as a screw for fixing the muffling band, and there is an effect that the attachment and detachment can be easily performed.
