Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a manual or electric storm shutter device, which can be used for openings such as windows of houses.

[Background technology]

FIG. 3 shows a conventional electric storm shutter device installed at openings such as windows of houses.

In this conventional device, one slat 50 is formed by bending a strip-shaped plate member into an S-shaped cross section and curling the upper and lower ends thereof to provide an engaging portion 50A. 50 engaging portions 50A are rotatably connected one after another to form a shutter curtain 51. In addition, a pair of left and right shutter rails 52 integrally formed on a sash such as a window are provided at the opening 60A of the house 60.
A shutter curtain 51 can be moved up and down along this shutter rail 52.

The upper end of the shutter curtain 51 is coupled to a drum 55 provided on one winding shaft 54 that is rotationally driven by a motor 53. The motor 53 is connected to this drum 5.
The winding shaft 54 is mounted on the opposite side of the house 60 across the winding shaft 54, and rotates the winding shaft 54 via a transmission 57 made of gears or the like. When the motor 53 is rotated forward or backward by operating a switch, the shutter curtain 51 is wound onto the drum 55 by the winding shaft 54 and unrolled, thereby opening and shielding the front surface of the opening 60A. The motor 53, the winding shaft 54, etc. constitute a shutter curtain winding and unwinding means for winding and unwinding the shutter curtain 51.

Motor 539 winding shaft 54. Drum 55, transmission 57
is arranged inside a shutter cover 58, and this shutter cover 58 has bolts 59A attached to the frame 59 of the house 60 at the outer wall 56 above the opening 60A such as a window.
It's stopped.

[Problem to be solved by the invention]

In a house where the vertical dimension of the opening 60A is large, the vertical dimension of the shutter curtain 51 is also large, and accordingly, the winding diameter of the shutter curtain 51 when wound around the drum 55 becomes large.

Further, in order for the shutter curtain 51 to be able to sufficiently withstand large wind pressure, the width dimension W of the slat 50 must be increased in order to increase the rigidity of the slat 50. The winding diameter becomes larger.

When the winding diameter of the shutter curtain 51 increases in this way, the shutter cover 58 must be made larger not only in the front-rear direction but also in the up-down direction.
According to this, a problem arises in that the shutter cover 58 is out of proportion to the house 60.

The purpose of the present invention is to prevent the vertical dimensions of the shutter and ivy cover from increasing even if the vertical dimensions of the shutter curtain and the width of the slats increase, and to maintain the front and rear dimensions almost the same as conventional ones. We provide storm door shutter devices that can.

[Means to solve the problem]

A rain shutter device according to the present invention includes a shutter cover attached to an upper outer wall of an opening in a house, and a shutter curtain roll that winds up and unwinds a shutter curtain that is placed inside the shutter cover and blocks the front surface of the opening. A rain door shutter device equipped with a take-out means, characterized in that the shutter curtain take-up and pay-out means includes two horizontal winding shafts arranged in parallel in the front-rear direction of the house. It is.

The winding and unwinding of the shutter curtain onto the winding shaft may be performed by a motor (or may be performed by a balance spring).

Further, in the rain shutter device according to the present invention, the shutter curtain winding and feeding means includes the two winding shafts and a motor disposed between these winding shafts and rotating the winding shafts. It is composed of:

[Effect]

By rotating the winding shaft forward and backward, the shutter curtain is wound and unwound by the winding shaft, as in the conventional case.

Since the shutter curtain is rolled up using two winding shafts arranged in parallel in the front and back direction of the house, there is no need to increase the vertical dimensions of the shutter cover.
When the motor is disposed between these winding shafts, the front and rear dimensions of the shutter cover are not much different from those of conventional shutter covers.

〔Example〕

An embodiment of the present invention will be described below based on the accompanying drawings.

1 and 2 show a side sectional view and a perspective view of essential parts of a rain shutter device according to the present embodiment.

In FIG. 1, the upper end of the shutter curtain 20 is coupled to a shutter curtain winding and feeding means 30 disposed within the shutter cover IO. The shutter curtain winding and feeding means 30 includes two horizontal winding shafts 31 arranged in parallel in the front-rear direction of the house 60, and is arranged between these two winding shafts 31. It is configured to include a motor 32 for rotating the.

The shutter curtain 20 is similar to the conventional example described above,
By curling the upper and lower end portions of a rectangular plate member bent into an S-shaped cross section, a plurality of slats 21 having upper and lower engaging portions 21A are formed, and the retaining portions 21
It is formed by sequentially arranging the respective slats 21 in a rotatable manner at A. The vertical length of the shutter curtain 20 is determined by the vertical dimensions of an opening 60A such as a window or a doorway of the house 60. The shutter curtain 20 can move up and down along a shutter rail 40 into which a stopper 22 at the lower end is inserted and engaged, and the shutter rail 40 is integrally formed with a sash such as a window.

The shutter curtain winding and unwinding means 30 that winds up and unwinds the shutter curtain 20 includes a shutter cover I.
It is attached to the inner surface of the two left and right side plates 11 of O. The two horizontal winding shafts 31, which are part of this shutter curtain winding and feeding means 30,
It is rotatably supported by bearings 11A on two left and right side plates 11 at a predetermined interval in the front-rear direction of the house 60. Drums 33 are fixed to these winding shafts 31 near both ends thereof, and a chain band 34 is wound between these drums 33. And this chain belt 3
4 is connected to the upper end of the shutter curtain 20.

Also, two winding shafts 3 are attached to one bracket 11.
A motor 32 is fixed between the winding shafts 1 and 1, and this motor 32 is connected to one of the two winding shafts 31 via a transmission 35 such as a gear.

The shutter cover 10 has a flat box-shaped cross section and includes a shutter curtain winding and feeding means 30 including a motor 32, a transmission 35, a winding shaft 31, a drum 33, and a chain band 34. The rear surface of this shutter cover 10 on the house 60 side serves as a mounting base plate 12. Further, a slit 13 through which the shutter curtain 20 enters and exits is provided on the lower surface of the shutter cover 10. The shutter cover IO is attached to the base plate 12
is attached to the outer wall 56 at the top of the opening 60A, and is attached to the frame 59 of the house 60 with bolts 59A.

Next, the operation of the shutter device according to this embodiment will be explained.

When opening the shutter curtain 20, the motor 32 is rotated in the forward direction by operating a switch.
The winding shaft 31 to which 5 is connected is rotated in one direction, and the other winding shafts 31 are also rotated in the same direction via the chain band 34. As a result, the shutter curtain 20 is wound up into an oval shape around the winding shaft 31 and the chain band 34, and also rises and opens along the shutter rail 40.

When closing the shutter curtain 20, the motor 32 is rotated in the opposite direction, thereby rotating the winding shaft 31 and the chain band 34 in the opposite direction, and the shutter curtain 20 is let out from the chain band 34.

According to this embodiment, the following effects can be obtained.

Since the vertical dimensions of the opening 60A are large, the vertical dimensions of the shutter curtain 20 are large, and the slats 21
Even if the width dimension W of the slat 21 is increased to increase the rigidity against wind pressure, the shutter curtain 20 is wound in an elliptical shape around two winding shafts 31 arranged in parallel in the front and back direction of the house 60. Therefore, the vertical winding space can be reduced compared to the case of winding around a single winding shaft as shown in the conventional example.

Further, since the motor 32 is disposed between the two winding shafts 31, there is no need to increase the winding space in the front and back direction as compared to the conventional shutter device. Therefore, the vertical dimension of the shutter cover 10 does not increase, and the longitudinal dimension is almost the same as that of the conventional example, so that when attached to the house 60, the appearance of the house 60 is not impaired.

In addition, the shutter cover 10 having such dimensions can have an opening 60 such as a window by sloping its top surface.
It can also be used as a canopy for A.

Note that the present invention is not limited to the above embodiments,
It also includes the following modified embodiments.

That is, in the embodiment described above, the two winding shafts 31 are equipped with the drums 33, and the chain belt 34 is looped between the drums 33. , for example, pulleys and belts may be used.

Also, a winding shaft 3 rotationally driven by a motor 32
In the embodiment described above, either one of the winding shafts is used, but the two winding shafts may be rotated at the same time.

Furthermore, in the embodiment, the drum 33 is connected to each winding shaft 3.
Although the chain belt 34 is fixed only near both ends of the drum and wrapped around it, the number of these is not limited to this, and the drum and chain belt can be wound continuously over the entire length of the shaft. It may be provided.

Furthermore, although the cross-sectional shape of the slat was S-shaped in the above embodiment, this cross-sectional shape is not limited to this either.

Further, a spiral spring is provided on one or both of the winding shafts 31, and this spring is configured to accumulate pressure when the shutter curtain 20 is unrolled.
The output of the motor 32 may be reduced by utilizing this accumulated pressure when winding up the material.

Furthermore, although the motor 32 was used in the above embodiments, instead of using a motor, a balance spring in the form of a coil is provided on one or both of the winding shafts, which accumulates pressure when manually unwinding the shutter curtain. The shutter curtain may be wound up using this accumulated force.

〔Effect of the invention〕

As explained above, according to the rain shutter device of the present invention, since the shutter curtain is wound up and let out by two winding shafts arranged in parallel in the front and back direction of the house, the vertical dimension of the shutter cover is Furthermore, if the motor is disposed between two take-up shafts, the front and rear dimensions of the shutter cover can be made almost the same as in the conventional example even if there are two take-up shafts.
