[Problems to be Solved by the Invention] However, in this type of shutter, when the shutter curtain is opened and closed, the engaging portions of the interlock portions generate noise due to relative movement, rotation, and the like. Further, in the panel slat, when the panel is wound on the winding shaft, the panel comes into contact with the shutter curtain wound up earlier, so that the generation of this noise is also a disadvantage.

[Means for Solving the Problems] In view of the above situation, the present invention has been created to eliminate these disadvantages, and a completely new structure has been added to the interlock portion itself in the prior art. In order to form a shutter curtain continuous in a vertical direction by connecting a plurality of slats vertically arranged vertically through a connecting member and forming a shutter curtain continuous in a vertical direction, the connecting member is formed on the lower side of the upper slat. An upper engaging portion for locking the upper slat and a lower engaging portion for locking the upper side of the lower slat adjacent to the upper slat are formed of a hard synthetic resin, and a bend made of a soft synthetic resin is provided between the respective engaging portions. A flexible connecting member is integrally connected, and is located inside the connecting member which is bent at the time of winding, and a side portion of the same quality as the connecting member is provided between the upper and lower engaging portions with a predetermined space therebetween. Articulated, shutter car When the ten is wound around the winding shaft, the side portion is bulged toward the center of the winding. With this structure, it is an object of the present invention to provide a structure of a connecting portion of a shutter slat which does not generate metallic noise during a raising / lowering operation of a shutter curtain.

[Embodiment] The configuration of the present invention will be described based on an embodiment shown in the drawings. First, a front view of a shutter employing the present invention, 1 is a shutter curtain, 2 is a shutter curtain 1 Is a horizontal connecting portion of the vertically adjacent slats 2, 2, and 4 is a winding shaft. In addition, 5 is a shutter case, and 6 is a guide rail.

As shown in FIG. 2, each of the slats 2 of the present invention comprises a main body 21 and upper and lower engaging portions 22 formed integrally with the main body 21 and bent to be engaged with the connecting portion 3. Has become.

Further, in the present invention, a synthetic resin interlock member 30 is employed as a connecting member in the connecting portion 3, and the interlock member 30 is provided with engaging portions 31 on both upper and lower edges.
And an intermediate portion 32 between these,
An engaging groove 31 having the same cross section as the engaging portion 22 of the slat 2 is provided at 31.
33 are formed, and the entire engaging portion 31 is molded using a hard synthetic resin.

Next, the interposition part 32 has a connecting member 34 located at the center in the thickness direction, and thin side parts 35, 35 connecting the upper and lower engaging parts 31, 31 at the front and back positions sandwiching the connecting member 34, Spaces 36, 36 separating the connecting member 34 and the side surface 35 are provided.
Are formed integrally with each other.

A soft synthetic resin is used for the interposition part 32, and is synthesized and molded as the connecting member 30 integrated with the fastening part 31 of the soft synthetic resin.

FIG. 3 shows another embodiment of the interlock member 30. In this example, the above configuration is exactly the same,
A reinforcing steel plate 40 penetrating through the connecting member 34 is formed integrally with the engaging portion 31 and the interposition portion 32 over the entire length in the longitudinal direction. The reinforcing steel plate 40 is a thin flexible steel plate,
The main part located at the center of the thickness of the connecting member 34 of the interposition part 32
41 and a reinforcing portion 42 that extends up and down and is buried around the engaging groove 33 inside the engaging portion 31 and is bent and formed corresponding to the shape of the engaging portion 22 of the slat 2. That is, the engaging portion 31 of the interlock member 30 is mainly reinforced.

[Operation] In order to form the shutter curtain 12 by the configuration of each part as described above, the engagement groove of the interlock member 30 is formed at the end of one engagement part 22 of the slat 2 in FIG.
33, and then slide in the longitudinal direction to engage the engaging portion 22 with the engaging portion 31 of the interlock member 30.

A number of the slats 2 prepared as described above are prepared, and the other engaging portion 31 of the interlock member 30 attached to the adjacent slat 2 is slid on the engaging portion 22 on which the interlock member 30 is not engaged. When the slats 2 are moved and engaged, the slats 2 are sequentially bound with the interlock member 30 as the connecting portion 3, and the shutter curtain 1 can be formed. Of course, the formation of the shutter curtain 1 is not limited to the procedure of the above embodiment, and the connection of the slats 2 and the interlock member 30 may be repeated alternately.

The shutter curtain 1 is formed by connecting a hanging slat to an upper end edge and attaching a seat plate to a lower end, and is wound around the winding shaft 4, but is also limited to assembling from above and assembling from below. There is no. Further, the shutter curtain 1 can be freely formed by continuously binding the shutter curtain 1 while winding it around the winding shaft 4 or by winding the continuously bound shutter curtain 1. Also, in the example having the reinforcing steel plate 40, the connection mode is the same.

The shutter curtain 1 thus configured is
Opening and closing by a switch (not shown) or a balance spring corresponding to the weight of the curtain is performed by a normal operation, but the operation at the connecting portion 3 is realized by the interlock member 30, particularly when bent. That is, the fastening portion 31 made of a hard synthetic resin transmits a force between the slats 2, and the interposition portion 32 made of a soft synthetic resin is provided between the slats 2 of the shutter curtain 1 in accordance with a normal interlock structure. Corresponds to the bending of

When the shutter curtain 1 is wound on the winding shaft 4, as shown in FIG. 4, the connecting member 34 of the soft synthetic resin interposed portion 32 is curved, and the side portion 35 on the outer peripheral side is slightly elongated. The connecting member 34 is separated from the connecting member 34 in the space 36 by the presence of the ridge 37 on the inner surface side. Although the inner side surface portion 35 is on the compression side, it does not shrink and bends out of the plane under the force. At this time, due to the presence of the ridge 37 on the inner surface side,
The inner peripheral side portion 35 bulges in the separating direction from the connecting member 34,
Slat 2 of shutter curtain 1 wound up earlier
By forming a constant gap in the wound state, the slats 2, 2 or the connecting portion 3, the interlock member 30, and the slats 2, which bulge, also overlap the inner side surface 35 itself at the inner and outer positions. And has a buffer function between them.

In addition, even in the interlock member 30 in which the reinforcing steel plate 40 is built in the interposition portion 32, the function of the interposition portion 32 at the time of bending is the same, except that the strength of the engagement portion 31 is increased.

[Effects of the Invention] In short, in the present invention, a plurality of slats arranged vertically one above the other are connected by a connecting member to form a shutter curtain that is continuous in the vertical direction. An upper engaging portion for engaging the lower side and a lower engaging portion for engaging the upper side of the lower slat adjacent to the upper slat are formed of a hard synthetic resin, and are formed of a soft synthetic resin between the above-mentioned respective engaging portions. A bendable connecting member is integrally connected, and is located inside the connecting member that is bent at the time of winding, and a side portion of the same quality as the connecting member is interposed between the upper and lower engaging portions with a predetermined space therebetween. When the shutter curtain is wound on the take-up shaft, the side portions are bulged in the direction of the center of the winding, so there is no loose fitting portion at the connection portion of the slat, and the shutter curtain Impact of lifting operation on the floor It is possible to provide a connection structure that is excellent in sound insulation and water tightness without any risk of metallic noise even when wind pressure is applied to the shutter surface, as well as during winding and winding. However, when the shutter curtain is wound around the winding shaft, the side surface portion located inside the connecting member on the outer periphery of the shutter curtain wound in advance faces the winding center direction. Since it bulges out, in addition to the basic function of the connecting member for binding the upper and lower slats, it also has a function as a cushioning material, and forms an appropriate gap between the preceding slat and the slat overlapping at the outer peripheral position. Thus, it is possible to prevent the noise and damage caused by the collision of the slats.
