Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shutter that can open and close an opening of a building.
[0002]
[Prior art]
In addition to the basic function of crime prevention, a shutter having a slat that opens and closes an opening of a building is also required to have ventilation, lighting, or dimming functions when the opening of the building is closed by a slat.
Shutters that are expected to perform these functions can be broadly classified into fold-up type shutters and roll-up type shutters, depending on the difference in the method of storing the slats in the shutter box.
The folding shutter has a structure in which each slat can be easily swung in a state in which the opening is closed by the slat, and exhibits sufficient functions such as ventilation and lighting.
[0003]
[Problems to be solved by the invention]
However, the mechanism for ventilation, etc. in the roll-up type shutter is often due to, for example, through holes provided between the slats continuous in the vertical direction, and functions such as sufficient ventilation, lighting, dimming have not been demonstrated. .
Further, even if there is one that can swing each slat, there is a troublesome operability.
[0004]
Accordingly, the present invention provides a roll-up type shutter that can provide not only crime prevention but also functions such as sufficient ventilation, lighting, and dimming by making the swinging operability of each slat comfortable. The main purpose is to provide
It is another object of the present invention to provide a slat having a new configuration and to provide a shutter that can be easily maintained.
[0005]
[Means for Solving the Problems]
  In order to achieve the above object, a plurality of slats, a hoisting and unwinding mechanism for winding and unwinding these slats, and a guide mechanism for guiding the slats wound up or unwound by the hoisting and unwinding mechanism In the shutter having a swinging mechanism for swinging the slat whose opening is closed through the guide mechanism, the swinging mechanism is rewound in a state in which the slat can swing by the hoisting and unwinding mechanism. The bottom slat at the bottom is lockedThe first and second telescopic means that are in the extended state when theThe slats are wound by the hoisting / unwinding mechanism,The second telescopic meansThe shutter is characterized in that the slat is rocked (the invention according to claim 1).
  According to the shutter, the opening / closing operation of the slat and the swinging operation of the slat can be performed by the same device. In addition, the slat can be swung and opened only by the slat hoisting operation. Sex can be made comfortable.
[0006]
In order to achieve the above object, the present invention provides a plurality of slats, a hoisting / rewinding mechanism for winding and unwinding these slats, and a guide for the slats wound or unwound by the hoisting / unwinding mechanism. And a swing mechanism that swings a slat that closes the opening of the building via the guide mechanism, the swing mechanism is from the next slat of the bottom slat to the slat at a predetermined position. First and second shaft means fixed to both ends of each slat, first mounting means for rotatably mounting the first shaft means, and second for rotatably mounting the second shaft means. And the lower end is fixed to both ends of the bottom slat, and the upper end is mounted at a predetermined position, and the first mounting means is disposed between the lower end and the upper end. A first telescopic means for connecting the slats, a lock means for locking the bottom slat to the guide mechanism side, and a lower end attached to the next-stage slat via the second attachment means. The upper ends are respectively attached to the slats at predetermined positions via the second attaching means, and the slats are connected via the second attaching means between the lower ends and the upper ends, and the locking means In the state where the bottom slat is locked, the slat is composed of second extendable means for swinging each slat around the first shaft means by operating the hoisting and rewinding mechanism. Invention described in 1.).
[0007]
Here, each of the first and second extendable / contractible means has an extension / contraction function that extends or shortens between the upper and lower ends.
In the shutter having the above-described configuration, when the slat is rewound by the hoisting / rewinding mechanism and the opening is closed by the slat via the guide mechanism, the bottom slat is locked by the locking means. The
At this time, the weight of the bottom slat or each slat is transmitted to the first and second extendable means via the first and second shaft means and the first and second attachment means, The second telescopic means are in an extended state, and each slat is in a swingable state.
Therefore, contrary to the slat unwinding, when the slat is wound up by operating the hoisting / unwinding mechanism, the lower end of the first telescopic means is moved through the bottom slat locked as described above. Since it is fixed, the first telescopic means cannot be wound up while maintaining the extended state.
On the other hand, the hoisting force of the slats winds up the second telescopic means, and as a result, the second shaft means is centered on the first shaft means rotatably attached to the first attachment means. It can be rotated like a fan to swing each slat.
Therefore, the opening / closing operation of the slats and the swinging operation of the slats can be performed by the same device. In addition, the slats can be swung and opened only by the slat hoisting operation. Can be a thing.
[0008]
It is desirable to provide a holding device for holding the lock of the locking means (the shutter according to claim 3).
Even if the slat is in an open state rotated in the horizontal direction due to the swinging of the slat, the lock means is held by the holding device, so that the security function can be fully implemented.
[0009]
  The slat is composed of a slat body and slat holders attached to both ends of the slat body, and the slat body is a hollow extrusion mold material, and is attached to a fixing hole provided near both ends of the back surface on the indoor side. Desirably, the slat holder is attached by fitting the fixing protrusion of the slat holder.That's right.
  The conventional attachment part which comprises the both ends of a slat was being fixed to the slat main body with the screw | thread etc. In the slat according to the present invention, the slat main body is made of a hollow extruded mold material and has sufficient rigidity, and the fixing projection of the slat holder is formed in the fixing hole provided near both ends of the indoor side surface of the slat main body. Since the slat holder is attached to the slat main body, the manufacturing process can be simplified and the cost can be reduced.
[0010]
  In each of the above-mentioned inventions, it is desirable that the slat take-up drive unit is separated from the slat take-up unit with respect to a hoisting and rewinding mechanism comprising a slat take-up unit and a slat take-up drive unit that drives the slat take-up unit.Good.
  In a conventional roll-up type shutter, the slat take-up portion and the slat take-up drive portion are coaxially attached. However, in this conventional structure, when a trouble occurs in the drive unit, the place where the trouble occurs is hindered by the slats, and it may be difficult to find out. On the other hand, in the present invention, the slat take-up drive unit can be separated from the slat take-up unit, and can be separated from each other so that each part can be easily seen, thereby facilitating maintenance of the hoisting and unwinding mechanism.
[0011]
In the above invention, the slat take-up drive unit is preferably disposed between the building frame and the slat.That's right.
  Since the conventional roll-up shutter has a shaft or the like interposed between the slat take-up drive unit and the operation means provided on the indoor side, it has been necessary to make a hole or the like on the wall on the indoor side. In some cases, the design of the inner wall was damaged by the construction. On the other hand, in the present invention provided with the slat take-up drive unit separated from the slat take-up unit, the slat take-up drive unit can be disposed between the building frame and the slat. Thus, it is not necessary to make a special internal wall, and the interior design is excellent, and the ease of maintenance can be enhanced.

The locking projections 662 and 662 pull the connecting rods 667 and 667, respectively.
As a result, the engaging portions 60, 60 are separated from the engaging pins 63, 63 against the urging force of the springs 61, 61, and the lock is released.
[0028]
A stop claw 663a is formed in the lower part of the rotating body 663, and the stop claw 663a can maintain the unlocked state by climbing over the peak of the leaf spring 665a fixed to the main body 665. ing.
Thus, by providing the lock release device 66, even if the opening O is closed by the slat 1, the lock can be released by a simple operation of turning the turning lever 660. Therefore, it is possible to quickly cope with an emergency such as a fire.
[0029]
It is preferable that the locked state of the locking means can be maintained even when the slats 1 are opened. A configuration example of the holding device will be described with reference to FIGS.
This holding device includes a restricting device 67 that makes the rotating lever 660 detachable from the rotating body 663 and restricts the rotation of the rotating lever 660 at the lock position.
[0030]

The regulating device 67 includes a rail groove 670 provided on the back surface of the next-stage slat 11 of the bottom slat 10 and a slide plate 671 that slides on the rail groove 670.
[0031]
The method of using the holding device is as follows.
First, the rotating lever 660 in the locked state is pulled out from the pocket 660 a of the rotating body 663.
Next, the slide plate 671 is slid along the rail groove 670 from the right position to the left position in the drawing.
Thereafter, the pulled rotation lever 660 is returned to the pocket 660a, and the slat 1 is swung to the open state.
[0032]
According to this holding device, as shown in FIG. 17, the rotation of the rotation lever 660 is restricted by the slide plate 671, the locked state is maintained, and the security can be maintained even when the slat is opened.
Of course, even in the closed state before the slats are opened, that is, in the state where each slat 1 is shown in FIG. 16, the security can be improved by causing the holding device to act similarly.
[0033]
Next, a preferred configuration example of the slat 1 will be described with reference to FIGS.
The slat 1 includes a slat main body 100 and a slat holder 110 fitted to both ends of the main body 100 in the longitudinal direction.
[0034]
The slat body 100 is formed by, for example, extrusion molding of a metal material such as aluminum, and has a hollow body portion 101, an upper end portion 1a formed above the body portion 101, and a lower end portion formed below. It consists of 1b.
[0035]
The back surface 105 facing the indoor side of the body portion 101 is provided with fixing hole portions 102 and 102 at positions near the both ends along the center line in the longitudinal direction. 102, the slat holders 110, 110 are inserted and attached through the hollow openings 103, 103 at both ends of the body 101.
[0036]
The slat body 100 having such a configuration is formed with a plate thickness of about 0.6 mm. Since it is extrusion molding, sufficient rigidity can be obtained even in a hollow shape with a thickness of 0.6 mm, so that the manufacturing cost can be reduced and the weight of the product itself can also be reduced.
[0037]
The slat holder 110 includes an insertion portion 111 inserted from the hollow openings 103 and 103 and a flange portion 112 that closes the hollow openings 103 and 103.
Since the left and right slat holders 110, 110 have the same configuration, one slat holder 110 is shown in FIG.
[0038]
The insertion portion 111 is tapered from a base portion 111a having substantially the same shape as the hollow shape of the body portion 101 in the direction of the distal end 111b, and is formed in a wedge shape.
A notch 111c is formed at substantially the center of the insertion portion 111, and a fixing protrusion 111d having a stepped cross section provided with elasticity by the notch 111c is provided.
[0039]
The flange portion 112 has a shape similar to the cross-sectional shape of the slat main body 100, and is engaged with the upper engagement portion 112a and the lower engagement so as to correspond to the upper end portion 1a and the lower end portion 1b of the slat main body 100, respectively. A portion 112b is formed.
[0040]
When the insertion portion 111 of the slat holder 110 configured as described above is inserted until the collar portion 112 contacts the hollow opening 107 of the slat body 100, the fixing hole portion 106 of the slat body 100 is The fixing projection 111 d of the slat holder 110 is fitted, and the slat holder 110 is fixed to the slat body 100.
[0041]
Since the slat 1 having the above-described configuration is an extruded aluminum hollow material, the slat 1 has high rigidity and wind resistance. Therefore, it is possible to prevent the slats from vibrating due to an external force such as wind pressure.
In addition, since the surface 104 of the slat 1 swells outward, dust or the like on the slat surface 104 is easily washed away by rain or the like.
Further, since the slat holder 110 is fitted to the slat body 100, the slat 1 can be assembled with one touch.
[0042]
Next, a preferred configuration example of the hoisting / rewinding mechanism will be described.

A drive unit is composed of a drive shaft 311 and a pulley 312 fixed to the shaft 311, and a ball chain 313 as slat operating means for applying a rotational driving force to the pulley 312.
[0045]
As described above, in the shutter according to the present invention, when the slat take-up drive unit 31 is separated from the slat take-up unit 30, when a trouble occurs in the drive unit, the location where the trouble occurs prevents the slat 1. Therefore, the discovery becomes easy, and the maintenance of the hoisting / rewinding mechanism 3 can be facilitated.
[0046]
The slat take-up drive unit 31 is disposed below the slat take-up unit 30 and between the building case K and the slat 1 via an attachment frame 314 fixed to the building case side.
Therefore, the construction of the inner wall as in the conventional example is not required, the interior design is excellent, and the ease of maintenance is increased.
The pulley 312 and the ball chain 313 that applies a rotational force to the pulley 312 are covered by a cover 315 fixed to the mounting frame 314 and are fed out from the feed port 316 of the box 2. .
[0047]
Next, the holder 317 for the ball chain fixed to the feeding opening 316 will be described with reference to FIGS.

The holder 317 has a plate body 317b continuous to the feeding port 316 and is cut to correspond to the diameter of the connection portion 313a of the indoor ball chain 313c. It is configured by providing a notch 317d.
Therefore, the structure of the holder 317 for restricting the movement of the slat 1 can be simplified.
[0048]
As shown in FIGS. 26 and 27, the shutter box 2 that accommodates the hoisting / rewinding mechanism 3 is divided into a cover main body 20 and a housing-side mounting portion 21, and the cover main body 20 includes the slats. A guide piece 22 is provided to guide the winding and unwinding of 1, 1, 1.
The housing side attachment portion 21 is a portion fixed to the housing side before finishing the wall around the opening O, and is composed of an upper piece 210 and left and right side pieces 211.
In addition, even if the slat 1 in which the front side 104 and the back surface 105 are respectively inflated outward by the guide piece 22 is wound inward from the outside to the indoor side, the travel width of the shutter can be reduced as much as possible. It has become.
[0049]
The procedure for attaching the shutter having the above structure to the housing side is as follows.
First, before finishing the wall, the housing side mounting portion 21 of the shutter box 2 is fixed to the upper portion of the opening O, and the lower frame 41 (see FIG. 1) and the guide frames 40 and 40 are fixed to the lower portion of the opening O. . Then, finish the wall.
In this case, only the housing-side mounting portion 21 of the shutter box 2 is fixed to the housing side, so that the wall finishing work is easy.
Finally, a shutter main body such as a hoisting and rewinding mechanism is incorporated in the left and right side pieces 211, and the cover main body 20 is fixed to the housing side mounting portion 21.
Therefore, the workability of wall finishing is improved by attaching only the housing side attaching part 21 to the housing side before the wall finishing.
