Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an architectural shutter, and more particularly to a shutter slat having a hollow portion on the back surface of the slat.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, this type of shutter slat forms a hollow portion H by fixing a back plate 7 having a substantially handle-shaped cross section to the back surface of the slat main body 6 and a sound insulating material in the hollow portion H. The interior material 8 such as a heat insulating material is loaded to prevent propagation of heat and sound indoors and outdoors.
[0003]
[Problems to be solved by the invention]
According to the shutter slat 5 in the above conventional example, the slat main body 6 and the back plate 7 are fixed by welding, so that the assembling work is complicated, and a welding mark W is exposed on the indoor side or by welding heat. There was concern that the slats would be deformed. In addition, because it is not possible to use materials such as colored steel plates with high designability as the material for slats (not suitable for welding), there is a problem such as a monotonous and tasteless design that damages the exterior of the building. . Furthermore, in the operation of welding the back plate 7 to the slat body 6, a space X in which the welding rod S can be inserted between the slat coupling piece 6b and the back plate 7 must be ensured. As a result, a sufficient heat insulation (heat insulation) performance could not be maintained.
[0004]
[Means for Solving the Problems]
The present invention has been made in view of the above-described circumstances, and has been created to eliminate the conventional problems, and includes a slat body having coupling pieces connectable to upper and lower edges of the slat surface, and a back surface of the slat body. In a building shirt slat composed of a back plate fixed so as to form a hollow part, the slat body has a folded shape toward one of the upper and lower edges of the slat surface toward the inside of the slat. A retaining groove having a substantially U-shaped cross-section that can form the hollow portion on the back plate, and bent from one end side of the housing groove toward the inner side of the housing groove. The formed first flange piece and the second flange piece projecting outward from the receiving groove from the other end side are formed, the second flange piece is engaged with the locking groove and the first flange piece is bonded. To adhere to the back of the slats It was.
[0005]
Moreover, it can be set as the shutter slat excellent in sound-insulation property or heat insulation property by loading the interior part of the sound insulation material or the heat insulating material in the said hollow part.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an architectural shutter slat according to the present invention will be described with reference to FIGS. In FIG. 1, a building shutter apparatus 1 is wound or unwound based on a winding shaft 2 horizontally mounted on the ceiling of a housing and forward / reverse rotation of the winding shaft 2 to raise and lower an opening. The shutter curtain 3 moves and the guide rail 4 guides both ends of the shutter curtain 3. In addition, it is needless to say that various member devices such as an opening / closing device are provided. However, since these are the same as known shutter devices for construction, description thereof is omitted.
[0007]
The shutter curtain 3 is formed by continuously binding a plurality of slats 5 and is wound around the outer periphery of the take-up shaft 2 when fully opened and stored in the ceiling, while being fully closed, the vertical surface extends over the entire opening. Is configured to be deployed.
The slat 5 includes a slat body 6, a back plate 7 attached to the back surface of the slat body, and an interior material 8 loaded between the slat body and the back plate.
[0008]
The slat main body 6 has a flat slat surface 6a at the center, a hook-shaped coupling piece 6b is obliquely upward on the back surface side at the upper end of the slat surface 6a, and is directed upward on the back surface side at the lower end. A folded portion 6c that is bent and a curled connecting piece 6d that is formed continuously with the folded portion 6c. Further, a locking groove 6e formed by the folded portion 6c is formed on the back surface of the lower end of the slat surface 6a.
The slat main body 6 configured as described above forms a series of swingable shutter curtains 3 by sequentially connecting the coupling pieces 6b to the coupling pieces 6d of the other slat main bodies.
[0009]
The back plate 7 is made of metal bending member has the leading end of a substantially U-shaped receiving groove 7a and the housing groove 7a and the first flange piece 7b and a second flange members 7c, respectively . The housing groove 7a forms a hollow portion H between the back surface of the slat main body 6 and can be loaded with an interior material 8 to be described later. The first flange piece 7b is bent from the front end of the receiving groove 7a toward the inside of the receiving groove of the back plate 7, while the second flange piece 7c is formed from the front end of the receiving groove 7a to the outside of the receiving groove. It is formed to protrude. The back plate 7 has a function as a container for the interior material 8, and also has a function as a reinforcing material for the slat 5 by forming a hollow portion H on the back surface of the slat body 6. The interior material 8 comprises an elastic material 8a made of rock wool, glass wool or the like and a vibration control rubber 8b. The elastic material 8a is fixed to the groove bottom of the receiving groove 7a of the back plate 7, while the vibration control rubber. 8b is fixed to the back surface of the slat body.
[0010]
Next, a procedure for assembling the slat 5 according to the present embodiment will be described. First, the damping rubber 8b is fixed to the back surface of the slat body 6 with an adhesive or the like in advance. Next, the elastic material 8a is fixed to the accommodation groove 7a of the back plate 7 by a known means such as an adhesive, and an adhesive 9 (a double-sided tape may be used) is applied to the outer surface of the first flange piece 7b. . Then, the second flange piece 7c is inserted into the locking groove 6e formed on the back surface of the slat body 6 to engage the lower end, and the adhesive surface of the first flange piece 7b is attached to the back surface of the slat surface 6a. . The assembling work of the slat 5 is completed by the above work.
[0011]
In this embodiment, the sound insulating material is adopted as the interior material to be loaded in the hollow portion H of the slat. However, the present invention is not limited to this, and a heat insulating material or the like is loaded into the heat insulating slat, or A simple hollow slat may be used without loading the interior material. Further, even if the slat of the present embodiment is used upside down, it can be used without any problem.
[0012]
【The invention's effect】
As described above, according to the present invention, since no welding work is required when assembling the slats, workability can be greatly improved, and welding marks are exposed on the indoor side. The material of the slat is not limited, and a shutter slat excellent in design can be provided.
[0013]
Further, since it is not necessary to form a space for inserting a welding rod, the non-sound insulation (heat insulation) portion can be made as small as possible, and a structure with better sound insulation or heat insulation can be obtained.
