(Configuration-shutter fire prevention structure)
Next, the fire prevention structure of the shutter 1 will be described. The shutter 1 includes a fireproof case 70 inside the shutter housing portion 20 in order to prevent the fire from spreading through the receiver 40 when the receiver 40 is burned or melted by the heat of fire. . 4 is a side view of the fireproof case 70, FIG. 5 is a view showing a first storage portion 80 to be described later of the fireproof case 70, (a) is a rear view, (b) is a bottom view, and (c) is a bottom view. FIG. 6 is a right side view, and FIG. 6 is a view showing a second storage portion 90 to be described later of the fireproof case 70, (a) is a rear view, (b) is a bottom view, and (c) is a right side view.

(Configuration-Shutter fire prevention structure-Fire prevention case)
The fireproof case 70 is a storage means for storing the receiver 40, and a storage means for suppressing the fire from spreading through the receiver 40 when the receiver 40 is burned or melted by the heat of a fire. It is. The fireproof case 70 is a long, substantially box-like body, and is installed so that the longitudinal direction of the casing 41 is substantially along the left-right direction. Specifically, the fireproof case 70 is configured by combining a first storage unit 80 and a second storage unit 90 with each other.

  Among these, the 1st accommodating part 80 is an inner-shaped hollow box-like body one size larger than the external shape of the receiver 40, One side surface (In this Embodiment, it is a rear surface. The surface shown) is open. The second storage portion 90 is a hollow box-like body having an inner shape that is slightly larger than the outer shape of the first storage portion 80, and one side surface thereof (in the present embodiment, the front surface is shown as a reference numeral 90a in FIG. 6). Surface) is open. Then, in a state where the receiver 40 is housed in the first housing portion 80, the side surface on the open side (the rear surface in the present embodiment) of the first housing portion 80 and the open side surface of the second housing portion 90. The fireproof case 70 is configured by covering the first storage unit 80 with the second storage unit 90 in such a direction that the side surfaces (the front surface in the present embodiment) face each other. In this state, the first storage unit 80 and the second storage unit 90 are fixed to each other. A specific structure for the fixing is arbitrary, and a known fitting structure or a fixing structure using a fixing tool can be applied. However, it is preferable to use a fixing structure having a fireproof property. In the embodiment, the mounting screw 71 is moved from the second storage portion 90 to the first storage through the screw hole 91 formed in the lower surface of the second storage portion 90 and the screw hole 81 formed in the lower surface of the first storage portion 80. By screwing into the part 80, the first storage part 80 and the second storage part 90 are fixed to each other.

  In addition, the fireproof case 70 can be made of any material. For example, when the receiver 40 is burned or melted by the heat of a fire, the fire is prevented from spreading through the receiver 40. From this viewpoint, it is preferable that the material has fire resistance, and further, from the general manufacturing needs, it is preferable that the material can reduce the manufacturing cost. For this reason, in the embodiment, steel is adopted as the material of the fireproof case 70. Or it is not restricted to this, For example, materials, such as a gypsum material and a fireproof fiber, may be employ | adopted.

  The fireproof case 70 can be manufactured by an arbitrary method. For example, the fireproof case 70 can be manufactured by bending a steel plate-like body.

  Since the receiver 40 is housed inside the fireproof case 70 configured in this manner, it is possible to prevent the fire from spreading even if the receiver 40 is burned or melted by the heat of the fire. Therefore, it is possible to improve the fire performance of the shutter 1 including the receiver 40. For this reason, it becomes possible to employ | adopt the shutter 1 provided with the receiver 40 as a shutter for fire prevention. Thus, for example, in the case where a plurality of shutters are installed in the same building, conventionally, a shutter equipped with the receiver 40 can be installed in a place where fire prevention is unnecessary, but fire prevention is necessary. Whereas it is necessary to install a shutter that does not include the receiver 40 at the place, and the specification and operation method of the shutter could not be unified, according to the present invention, the receiver 40 can be installed at any place. It becomes possible to install the shutter 1 equipped with this, and it becomes possible to unify the specification and operation method of the shutter.

(Configuration-Shutter fire prevention structure-Fire prevention case fixing structure)
Next, the fixing structure of the fireproof case 70 will be described. As the fixing structure of the fireproof case 70, any structure can be adopted as long as the fireproof case 70 can be installed inside the shutter housing portion 20. In the present embodiment, the following fixing structure is adopted. Has been.

  First, a fireproof case 70 and an opening / closing device 50 are arranged in parallel inside the shutter storage unit 20 along the longitudinal direction of the shutter storage unit 20. Specifically, in the present embodiment, as shown in FIGS. 1 and 2, the shutter storage portion 20 is formed in a longitudinal shape along the left-right direction. 50 are juxtaposed along the left-right direction. The mutual positional relationship between the fireproof case 70 and the opening / closing device 50 is arbitrary. However, for example, since the opening / closing device 50 is preferably disposed at a position close to the connection point of the winding shaft 60 with the opening / closing device 50, It is preferable that the connecting part of the take-up shaft 60 connected to the switch 50 (in the present embodiment, the vicinity of the right end of the take-up shaft 60), the switch 50, and the fireproof case 70 are arranged in this order. Thus, the reason why the fireproof case 70 and the switch 50 are arranged in parallel is as follows. That is, for example, it is conceivable that the fireproof case 70 and the opening / closing device 50 are juxtaposed along a direction (short direction) perpendicular to the longitudinal direction of the shutter storage unit 20. However, in such a case, since the length of the shutter storage unit 20 in the short direction is shorter than the length of the shutter storage unit 20 in the longitudinal direction, fire prevention is performed along the longitudinal direction of the shutter storage unit 20. Compared with the case 70 and the switch 50 arranged side by side, the use efficiency of the internal space of the shutter storage unit 20 is reduced, so that there is a space restriction in installing the fireproof case 70 and the switch 50. The possibility may arise, or it may be necessary to enlarge the shutter housing portion 20 as compared with the conventional case. Therefore, in order to solve such a problem, in the embodiment, the fireproof case 70 and the opening / closing device 50 are arranged in parallel along the longitudinal direction of the shutter storage unit 20, so that the inside of the shutter storage unit 20 is arranged. The fireproof case 70 and the opening / closing device 50 can be arranged along the space shape, and the use efficiency of the internal space of the shutter storage unit 20 can be improved.

  Moreover, the fireproof case 70 and the opening / closing machine 50 are fixed to each other. Specifically, as shown in FIG. 2, a contact portion 92 is integrally formed on the second connection piece 24. The contact portion 92 is a fixing means for fixing the opening / closing device 50 to the fireproof case 70, and protrudes toward the opening / closing device 50 from the end surface of the second connection piece 24 on the opening / closing device 50 side. Has been placed. The abutment portion 92 is formed in a substantially L-shaped side surface by a pair of abutment pieces 92a and 92b, and one abutment piece 92a abuts against the upper surface of the end portion on the fireproof case 70 side of the switch 50. The other abutment piece 92b is disposed along the vertical direction at a position that abuts against the front surface of the end of the switch case 50 on the fireproof case 70 side. The abutting portion 92 and the end portion of the opening / closing device 50 on the fireproof case 70 side are fixed to each other by a binding band 94, whereby the fireproof case 70 and the switch 50 are fixed to each other. The contact pieces 92a and 92b of the contact portion 92 are formed with groove portions (not shown) into which the binding band 94 is fitted. By binding the binding band 94 so as to fit into the groove portion, The binding band 94 can be more firmly fixed to the contact portion 92. Since the fireproof case 70 and the switch 50 are thus fixed to each other, the fireproof case 70 and the switch 50 can be handled integrally with each other, and the installation work can be performed. Property can be further improved.

  Further, the fireproof case 70 and the receiver 40 are fixed to the shutter housing portion 20 by a common fixing structure. That is, the second connection piece 24 is provided on the inner side surface of the front side portion of the shutter storage portion 20. As shown in FIG. 3, the second connection piece 24 is formed in a substantially S-shaped side surface, and is fixed to the shutter storage portion 20 by a mounting screw 25 at its lower end portion. The upper end extends to the front side of the fireproof case 70. On the other hand, a plurality of screw holes 44 are formed in the housing 41 of the receiver 40, and screw holes 82 are formed at positions corresponding to the plurality of screw holes 44 on the front surface of the first storage portion 80 of the fireproof case 70. The fireproof case 70 and the receiver 40 are attached to the shutter housing portion 20 by screwing a common mounting screw 72 through which the screw hole 44 and the screw hole 82 are sequentially inserted into the second connection piece 24. It is fixed. Thus, by fixing the fireproof case 70 and the receiver 40 to the shutter storage unit 20 by screwing the common mounting screw 72 into the second connection piece 24, the fireproof case 70 and the receiver 40 are fixed. As compared with the case where the two are individually fixed to the shutter storage unit 20, the fixing structure can be simplified.

(Configuration-Shutter fire prevention structure-Wiring structure)
Next, the wiring structure of the fireproof case 70 will be described. As the wiring structure of the fireproof case 70, an arbitrary structure is adopted as long as the fireproof case 70 and the receiver 40 can be connected to each other via the first power line 5, the second power line 6, and the signal line 7 described above. However, in the present embodiment, the following wiring structure is employed.
