[0007]

An embodiment of the present invention will be described below with reference to the drawings.

The building shutter shown in FIGS. 1 to 5 shows an example in which the shutter is applied to an entrance of a wide frontage, and has three sets of shutter units 1C, 1R, and 1L.

A frame-like frame 4 is mounted on the ceiling surface 3 at the center of the entrance 2 and a shutter unit 1C at the center is supported by the frame 4. Shutter units 1R and 1L located at both ends are connected to one end of the frame 4. And the other end is supported by side walls 5R and 5L.

Hereinafter, the central shutter unit 1C will be described with reference to FIGS.

The frame 4 includes a flat rectangular frame 6 and vertical members 7, 8, 9, 10 provided at appropriate positions in the vertical direction, and vertical members 7, 9, 10 and frame members 6 located near both ends. It is composed of a right substrate 11 and a left substrate 12 which are provided to extend.

Horizontal support beams 13 and 14 are attached to lower end positions of the right substrate 11 and the left substrate 12, respectively, and the shutter curtain take-up shaft 16C is rotatable on both support beams 13 and 14 via bearings 15 and 15, respectively. Attach.

At both ends of the winding shaft 16C, flanges 18 for preventing turbulence of the shutter curtain 17C are fixed. Also, one rotating shaft 19C of the winding shaft 16C
Is fitted with a driven sprocket 20C.

Brackets 21 and 21 are attached to the tips of the support beams 13 and 14, and guide rolls 23C are rotatably attached via bearings 22 and 22 fixed to the brackets 21 and 21, respectively.

A motor support 24C is fixed to the longitudinal member 10 on the side opposite to the take-up shaft, and a take-up motor 25C for taking up a shutter curtain is mounted on the motor support 24C. A drive sprocket 26C is fixed to the output shaft. A chain 27C is looped between the driving sprocket 26C and the driven sprocket 20C.

A net-shaped shutter curtain 17C is engaged with the winding shaft 16C by a shutter curtain engaging device 28C which will be described later.
Is hung around the guide roll 23C.
At the lower end of the shutter curtain 17C, a seat plate unit 29C described later is attached.

By driving the take-up motor 25C, the shutter curtain 17C is fed out or taken up, the entrance is opened and closed, and the shutter curtain 17C has transparency when closed. Further, since the shutter curtain is made of a net-like material, the inside is hard to be seen from the outside, and the outside is easily seen from the inside.

Next, the right shutter unit 1R will be described with reference to FIG.

The support beam 30 is located at a middle position of the right substrate 11.
And a shelf 31 is fixed to the right side wall 5R. A right take-up shaft 16R is rotatably attached to the support beam 30 and the shelf 31 via bearings 32,32.

At both ends of the right take-up shaft 16R, a shutter curtain 17R is provided similarly to the take-up shaft 16C.
Is provided with a flange 18 for preventing turbulence. A driven sprocket 20R is fitted to one rotating shaft 19R of the right winding shaft 16R.

Brackets 21 and 21 are attached to the ends of the support beam 30 and the shelf 31, respectively.
The right guide roll 23R is rotatably mounted via the bearings 22, 22 fixed to 1, 21.

A motor support 24R is fixed to the side of the vertical member 7 opposite to the right winding shaft, and a right winding motor 25R for winding the shutter curtain is mounted on the motor support 24R. A drive sprocket 26R is fixed to the output shaft of the motor 25R. The driving sprocket 26R and the driven sprocket 20R are connected via a chain 27R, and driven by the right winding motor 25R, the right winding shaft 16R moves the right shutter curtain 17R.
In the winding direction or in the feeding direction.

The right shutter curtain 17R has a net shape similarly to the above-described shutter curtain 17C. The right shutter curtain 17R is engaged with the right winding shaft 16R by a shutter curtain engaging device 28R which will be described later, and has a seat at its lower end. A plate unit 29R is mounted.

Next, the left shutter unit 1L has the same configuration except for the symmetric arrangement with respect to the right shutter unit 1R, and a description thereof will be omitted.

In the left shutter unit 1L,
16L is a left take-up shaft, 23L is a left guide roll, 25L is a left take-up motor, and 17L is a left shutter curtain.

Here, the shutter curtain 17C described above is used.
, 17R, and 17L are made of a net-like material. Examples of the net-like material include a stainless steel wire used for a belt conveyor and a finely woven steel wire. Such a net-like material is lightweight and has high strength.

As is apparent from the above configuration, the shutter in this embodiment has no guide for raising and lowering the shutter curtain, and the shutter curtains 17C, 17R and 17L are moved in the horizontal direction by the flanges 18 and 18 of the hanging base. Positioning is performed.

The winding motors 25C, 25R
, 25L to drive the shutter curtain 17C, 1
7R and 17L can be opened and closed. Also, the winding motor 25C,
The shutters 25R and 25L are preferably driven synchronously. However, since each shutter unit has a completely independent structure, it is not necessary to synchronize them strictly, and it is of course possible to open and close individually.

The shutter curtain engaging device 2 described above
8C, 28R, 28L, seat plate units 29C, 29R,
29L have the same configuration.

Next, the engaging device 28 of the shutter curtain 17 will be described with reference to FIGS.

A net-like material is easily deformed by a local load. Therefore, a local load does not act on the anchoring device 28 described below.

At the upper end of the shutter curtain 17, an end plate holder 33 in which a large-diameter coil is formed flat is attached, and the end plate 34 is inserted into the end plate holder 33.

The upper end of the shutter curtain 17 is attached to a hanging bracket 35 via the end plate 34 and the end plate holder 33.

The hanging bracket 35 comprises a shutter curtain gripping portion 36 folded back so that the gap corresponding to the thickness of the shutter curtain 17 is clear, and a joint portion 38 connectable to a slat 37 of a general shutter curtain. Gripper 36
And the joint portion 38 are connected by a required fastener 39 such as a bolt and a nut. Of course, the grip 36
The joint 38 and the joint 38 may be formed integrally.

The shutter curtain 17 is connected to the hanging bracket 35.
In order to mount the end plate holder 33, the end plate holder 33 is inserted into the grip portion 36 together with the end plate 34, and the end plate holder 33 is folded back.

A slat 37 is connected to the joint 38 so that the slat 37 substantially corresponds to one winding of the winding shaft 16.

The shutter curtain 17 is mounted on the winding shaft 16.
Is carried out via the above-described engaging device 28.

The endmost slat 37 is fixed to the winding shaft 16 with a bolt 40. Next, shutter curtain 1
7 is involved. Here, the reason why the slats 37 for approximately one turn are connected to the hanging bracket 35 is that the cross-sectional shape becomes substantially circular when wound.

After one turn of the slats 37, about two more turns of the shutter curtain 17 are wound, and the engagement of the shutter curtain 17 with the winding shaft 16 is completed. Although the end of the shutter curtain 17 is simply inserted into the hanging bracket 35 and turned over, the shutter curtain 17 is further wound, and the tightening force of the shutter curtain 17 causes the shutter shaft 17 to be wound onto the winding shaft 16. Is secured.

The seat plate unit 29 is shown in FIGS.
Will be described.

The shutter curtain 1 of the seat plate unit 19
7, the shutter curtain 17 is made of a net-like material in the same manner as the engagement device 28,
No local forces are applied.

At the lower end of the shutter curtain 17, an end plate holder 33 in which a large-diameter coil is formed flat is attached, and the end plate 34 is inserted into the end plate holder 33. The attachment to the seat plate unit 29 is performed via the end plate 34.

The seat plate unit 29 mainly includes a seat plate main body 41 and a seat plate cover 42.

The seat plate body 41 is formed by bending a plate material such as a stainless steel plate so as to have a substantially hollow L-shape. More specifically, the folded portion 43 facing the shutter curtain 17
From top surface 44, front side surface 45, bottom surface 46, bottom side surface 4
7. The shelf 48 is bent 90 ° in the same direction as the shelf 48, and then the bracket 49 is bent 90 ° in the opposite direction.

The seat plate cover 42 is formed so as to make up a rectangular section as a whole by compensating for the missing portion of the seat plate body 41.

More specifically, the upper surface 51, the back side surface 52, and the bottom portion 53 mounted on the shelf 48 are formed by being sequentially bent by 90 ° from the folded portion 50 facing the shutter curtain 17.

A pedestal fitting 55 to which a bolt 54 is fixed in advance is fixed inside the front side surface 45 of the seat plate body 41.

The bolt 54 pierced through the collar is inserted through the end plate 34, and an auxiliary metal fitting 56 formed in a step shape is inserted through the bolt 54. The auxiliary metal fitting 56 and the end plate 34 are fixed to the pedestal metal fitting 55 together with the nut 57.

The seat plate cover 42 is mounted on the shelf portion 48 and fastened to the auxiliary fitting 56 and the bracket portion 49 by a decorative screw 58 such as a countersunk screw, so that the seat plate body 41 is mounted. Attach to

Thus, the lower end of the shutter curtain 17 and the mounting structure at the lower end are all covered by the seat plate body 41 and the seat plate cover 42.

Next, the seat plate cover 42 is provided with a U-shaped hook fitting 60 which is paired with a fixing device 59 at the lower end of the shutter curtain, which will be described below, so as to be movable up and down.

The shutter curtain lower end fixing device 59 is shown in FIG.
This will be described with reference to FIG.

The key case 62 is embedded in the floor 61. The key case 62 has a flat boot-shaped space 64 into which a key plate 63 to be described later is inserted. The space 64 is formed in a plane perpendicular to the shutter curtain 17, and has a length of an upper end opening. Is sufficiently longer than the protruding length of the protrusion 65 at the bottom of the gap.

At the lower part of the key plate 63, there is formed a foot 66 which engages with the protruding portion 65.
A hook 67 projecting toward the shutter curtain is formed on the upper part of the shutter 3, and a recess 68 into which the hook metal fitting 60 is fitted is formed in the hook 67 from above.

In FIG. 11, reference numeral 69 denotes a lock plate for restricting the movement of the key plate 63 in the key case 62.

The lower end of the shutter curtain 17 may be fixed as follows.

First, the shutter curtain 17 is lowered and the seat plate unit 29 is grounded on the floor. The hook fitting 60 is pulled up, and the key plate 63 is inserted into the key case 62. After the insertion, the key plate 63 is slid to the shutter curtain 17 side. The foot 66 of the key plate 63 is
And a gap is formed on the key plate 63 on the side opposite to the shutter curtain 17. The lock plate 6 is inserted into the gap.
The key plate 63 is fixed by fitting the key plate 9.

Next, when the hook fitting 60 is lowered and fitted into the recess 68, the lower end of the shutter curtain 17 is fixed by the fixing device 59.

If a leaf spring or the like is provided along the recess 68 and the hook fitting 60 is brought into sliding contact with the recess 68 so as to be fitted into the recess 68, the friction between the leaf spring and the recess 68 causes the hook 68 to slide. And the hook fitting 60 is more stable.

When the shutter curtain is open, the key plate 63 and the lock plate 69 are in a detached state. The gap for inserting the key plate 63 and the lock plate 69 may be left in a slit shape without any particular problem in practical use, but a dummy plate 70 as shown in FIG. 13 may be fitted. A hook 71 is formed at a corner of the dummy plate 70 to facilitate removal.

In this embodiment, three sets of shutter units 1C, 1R, 1L are provided, but it is needless to say that two sets, one set, or four or more sets can be provided.

[0062]

As described above, according to the present invention , since the net-shaped shutter curtain is lightweight and has high strength, it has a high crime-prevention effect and can prevent the passage of small flying objects. In addition, since it is a net-shaped member, it has good transparency from the inside, but also has the effect that the inside is difficult to see from the outside. Further, since the shutter curtain is made of a net-like material, the winding diameter when winding is small, the space occupied by the winding section and the curtain storage section can be reduced, and the size of the apparatus can be reduced. Since the take-up shafts are arranged at different levels, they can be prevented from interfering with the adjacent take-up shafts, drive systems, etc., and a desired number of shutter units can be arranged, so that they can cope with the entrance of the main entrance. It is possible. Furthermore, since a guide rail is not used as a guide for the shutter curtain, the design is excellent, and a guide rail at the joint between the shutter curtains when a plurality of shutter units are arranged is not required, thereby greatly improving the workability. Further, since the net-shaped shutter curtain is securely fixed at the upper end and the lower end, the entrance can be safely closed without rigidity, and sufficient strength is exhibited.
