Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter curtain for a building to be built on a building such as a house or a building.

[Problems to be Solved by the Related Art and the Invention] Generally, a shutter curtain for a building of this type is wound around a winding drum disposed above an opening, and is provided on both left and right sides of the opening. It is common to use a guide rail formed to open and close vertically. By the way, it is necessary that the shutter curtain used for this product be formed so as to be transformed into a straight posture along the guide rail and a spiral posture wound on the winding drum. The slats thus formed are interlocked with each other to form a shutter curtain. However, in this case, since there is a play in the interlock connecting portion due to the gap, there is a problem that noise is generated when the air is blown when the door is opened or closed or when the door is closed.

Therefore, there have been attempts to eliminate the gap in the interlocking connection portion, but these methods have a problem that the structure of the interlocking connection portion becomes complicated, and are poor in reality.

Means for Solving the Problems In view of the above-mentioned circumstances, the present invention has been made with the object of providing a building shutter curtain capable of eliminating these drawbacks. In a shutter curtain for a building that is guided to open and close, the shutter curtain is formed by using a main slit formed of a rigid material and a sub-slat formed of an elastic material. At the upper and lower side edges, connecting portions projecting toward the indoor side are formed, these connecting portions are superimposed and connected integrally, and the shutter curtain is curved by the elastic deformation of the sub-slat. At the same time, the connecting portion of the main slide is further provided with a locking side extending to the sub-slat portion, and these adjacent locking sides can be freely bent at the sub-slat portion. It is characterized by being locked.

According to the present invention, the gap and the noise between the slats generated by the interlocking connection portion can be avoided by this configuration.

Example Next, an example of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a shutter curtain of a building shutter. The shutter curtain 1 is wound around a winding drum 2 built above an opening, and guide rails provided on the left and right of the opening. It is configured to be vertically opened and closed by being guided by 3.

The shutter curtain 1 includes a main slat 4 formed of a rigid material such as a metal material such as steel or aluminum or a synthetic resin material used for an existing shutter curtain, and a spring steel or a synthetic resin. It is constructed by alternately connecting sub-slats 5 formed of an elastic material such as a material.

In other words, in this embodiment, the main slat 4 is formed in a substantially U-shape toward the indoor side, and both legs are further folded back toward the outdoor side to form a hairpin groove-shaped opening with the outdoor side open. A mating portion composed of mating grooves 4a and 4b (for convenience, the upper portion is distinguished as an upper fitting groove portion 4a, and the lower portion is distinguished as a lower fitting groove portion 4b. This corresponds to a connecting portion of the present invention). Although formed, the fitting grooves 4a and 4b are inclined so as to be high on the indoor side and low on the outdoor side. An engaging hole 4c is formed on the outer side of each of the fitting grooves 4a and 4b at intervals of the pitch A. The length of the engaging hole 4c in the left-right direction (in the pitch A direction). Length) is set to B.
Further, locking edges 4d and 4e (from the present embodiment, extending from the leading edge of each of the fitting grooves 4a and 4b to five sub-slats to be fitted and connected to the fitting grooves 4a and 4b described later). Is an interlock type lock.) Is extended,
These upper and lower locking sides 4d and 4e are connected and locked so as to be freely bent.

On the other hand, the sub-slat 5 is formed by bending an arrow-shaped approximately U-shape, and the fitting sides 5a and 5b (for convenience, the upper one is the upper fitting side 5a and the lower one is the lower side. Is distinguished as the lower fitting side 5b.) Is the fitting groove of the main slide 4.
Like 4a and 4b, it is inclined so that the indoor side is high and the outdoor side is low. Further, an engagement piece 5c is formed by stamping so that the tip is on the crotch side and protrudes toward the opposite sides of both fitting sides. The engagement piece 5c is set so that the pitch is substantially half (B / 2) the length of the engagement hole 4c.

In the shutter curtain 1, the lower fitting side 5 b of the sub-slat 5 is engaged with the engaging piece 5 c in the upper fitting groove 4 a of the main slit 4 to which the locking sides 4 d and 4 e are locked in advance. It is formed by pushing and fitting until it engages with 4c, and pushing and fitting the upper fitting side 5a of the sub-slat 5 in the same manner into the lower fitting groove 4b to form a series. The shutter curtain 1 thus formed in a series is
The connection by the sub-slat 5 is the locking side 4d, 4e of the main
The priority is given to the engagement of the comrades, and at this time, the engagement of the locking sides 4d and 4e is in a loose state. The shutter curtain 1 is curved by the elastic deformation of the sub-slat 5 and wound around the winding drum 2.

In the embodiment of the present invention configured as described above, the opening and closing of the opening is performed by setting the shutter curtain 1 to the guide rail 3.
The shutter curtain 1 is formed by moving the rigid slats together by a conventional interlock connection such that the rigid slats can be bent freely. Is not present,
As a result, at the time of the opening / closing operation or when the wind is received, it is possible to reliably avoid the generation of noise due to the collision of the slats, and it is possible to provide a quiet low-noise building shutter. Further, since there is no gap between the connecting portions of the slats, there is an advantage that the fire prevention, the smoke prevention and the sound insulation are excellent.

In addition, in the case of winding on the take-up drum 2, not the rigid main slide 4 but the elastic and flexible auxiliary slide 5 is curved, so that only the conventional interlock connection is provided. Similarly to the above, it can be wound spirally without any problem.

In addition, in the event of a fire or the like, even if the auxiliary slide 5 made of a material having elasticity weak at high temperatures is burned and damaged, the main slide 4 made of a rigid material is locked. Since the engagement by the sides 4d and 4e still remains, the shutter curtain 1 will not be cut off and fall down, so that reliable fire protection can be achieved. Needless to say, security is very convenient.

Further, in this embodiment, each of the slats 4, 5
Since the connecting end portions of the competitors are not exposed to the outside, they are not only preferable in appearance but also very advantageous in rust prevention. In addition, there is an advantage that the rain closing when closing is excellent, and in addition, since the engaging piece 5c is fitted and engaged with the engaging hole 4c and the lateral displacement is restricted, the conventional interlocking connection is performed. There is also an advantage that there is no need to attach end fittings so that the slats do not shift left and right as in the case of the above.

The present invention is, of course, not limited to the above-described embodiment, and is, for example, a pattern diagram shown in FIG. 6 (where a solid line represents a main slit and a broken line represents a subslat). It may be hot. That is, the bent side has the same pattern as that of the first embodiment, but has a horizontal protruding shape (FIG. 6A), and a main slat 4 having a substantially Σ shape (FIG. 6B). The main slat 4 has a substantially semicircular arc shape (FIG. 6C), the main slat 4 has a substantially corrugated slat surface (FIG. 6D), the main slat surface Can be adopted, such as those having a zigzag shape (FIG. 6E), those having various patterns on the slat surface, and those having these patterns on the sub-slat 5 side. It is.

Further, as shown in the pattern diagram of FIG. 7, the storage of the shutter curtain is not limited to the one wound spirally around the winding drum as in the first embodiment described above. 7 (A in FIG. 7) and those housed in a horizontal storage rail 8 from the guide rail 3 via a curved rail (FIG. 7B).

[Effects] In summary, since the present invention is configured as described above, the shutter curtain is formed of a connecting portion of the main slat formed of a rigid material and an elastic material. Since there is no gap between adjacent slats, the slats are rubbed or abutted when opening or closing or receiving wind. The generation of unpleasant noise caused by the noise can be avoided, the noise can be significantly reduced, and the noise can be reduced. Further, since there is no gap between the adjacent slats, it can greatly contribute to the improvement of fire prevention, smoke prevention and sound insulation.

In addition, the connecting ends of these main and sub-slats are not exposed to the outside and are not only preferable in appearance but also very advantageous in security and rust prevention.

In addition, in this case, since the locking sides extending to the sub-slat part of the main sled are connected, the sub-slat made of a material having elasticity weak to temporary light heat burns in case of fire, etc. Even if it does, the shutter curtain will not be cut and dropped by the engagement of the locking edges of the main slats made of a rigid material, thus ensuring reliable fire protection. Can be achieved.
