Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for reinforcing a shutter, and more particularly, to a GORE-TEX (Japan Gore-Tex Co., Ltd.) composite film made of a special material on either the back or front surface or both the front and back surfaces of the shutter. (Product name of company)
In particular, the present invention relates to a shutter reinforcing device suitable for use in a shutter.

[0002]

2. Description of the Related Art Conventionally, a shutter is formed in an armor shape by locking both ends of a steel plate or aluminum, which are bent at both ends, so as to conform to an installation location, for example, the size of a doorway or a window. In addition, the cutting device is cut into an appropriate length and width, and is formed so as to be automatically or manually wound or unwound on a winding drum by power or manually or by the accumulating force of a spring as a lifting device.

[0003]

In the conventional shutter, a gap is formed even when the locking portions at both ends of the slat are firmly locked to each other. There is a problem that noise such as metal noise is generated due to friction with the frame when the shutter is opened and closed, especially when the shutter is opened and closed, and this cannot be prevented.

[0004] Therefore, the invention according to claim 1 or 2 of the present invention is to apply a reinforcing material to either the back or front surface of the shutter or both the front and back surfaces so that the winding or unwinding operation of the shutter can be smoothly performed. It is an object of the present invention to provide a shutter reinforcing device capable of performing the above operations. According to the third aspect of the present invention, in addition to the object of the first aspect of the present invention, at the time of winding or unwinding, at the locking portion of the shutter, internal and external pressures can be reduced and the shutter can be smoothly bent and extended. It is intended to provide a device.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 or 2 of the present invention is characterized in that one of the back and front surfaces of the shutter and the front and back surfaces can be made of a special material. Characterized in that a thin piece of the composite film is attached as a reinforcing means.

Here, the means for reinforcing the shutter is a means for enhancing the function of the shutter by preventing wind and water from entering the room and preventing noise when the shutter is opened and closed. In addition to preventing water, humidity, wind from entering and noise from the locking part,
All means that can improve the wear resistance.

[0007] With this structure, when the door is closed or the window is closed by the shutter, for example, wind and water do not enter the room due to the external pressure and do not hinder the goods or articles in the room. In addition, the humidity in the room passes through the composite membrane and dissipates outside through the gap between the locking portions of the shutter, and the noise and abrasion caused by the contact between the shutter and other metals such as the frame due to the soundproofing and abrasion resistance of the shutter. Opening and closing operation can be performed smoothly.

Here, the composite membrane is a membrane made of a special material having mechanical and chemical stability, and generally uses a Gore-Tex membrane (trade name of Japan Gore-Tex Corporation). In addition, almost all other Gore-Tex membranes (trade names of Japan Gore-Tex Co., Ltd.) and uniform microtex (trade names of Nitto Denko Co., Ltd.) can be used to provide this windproof, waterproof and transparent properties. The shutter can be reinforced by using the wetness.

Further, as in the third aspect of the present invention, a bulging portion is formed by a thin piece of the composite film at each locking portion of the slat of the shutter. When formed in this manner, bending and stretching between the shutter and the metal frame, which occur when the shutter is wound or unwound on the winding drum, is easily performed to provide a margin for the locking portion, thereby causing wear and noise of the shutter and noise. And the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In each of the drawings, FIG. 1 is a front view showing a mounted state of a shutter, FIGS. 2 and 3 are cross-sectional views of a main part showing a state where a composite film is adhered to a back surface of the shutter, and FIG. 4 is a back surface of a slat. 5 is a cross-sectional view of a main part showing a state where the composite film is adhered to the locking portion of FIG. 5. FIG. 5 is a cross-sectional view of a main part showing a state where the composite film is bonded to both the front and back surfaces of the shutter. FIG. 4 is a cross-sectional view of a main part showing a state in which a swelling portion of a composite film is formed on the front surface and no swelling portion is formed on the back surface.

First, referring to FIG. 1, an entire shutter reinforcing device will be described. However, the embodiment shown here shows a case where the present invention is used for a general entrance or a window, etc., and when this is used for a fire engine or the like, there is a slight difference in a winding device. It is considered something.

At right intervals, a right and left cross-shaped frame 1
a and 1b are erected, and both ends of the shutter slats 2 are inserted into the U-shaped cross-section frames 1a and 1b, and the slats 2 are moved along the frames 1a and 1b by manual or power operation. Raising and lowering can be easily accomplished.
In the case of manual operation, a cue hole 3 is opened on the left and right of the lower part of the slat 2, a hand is inserted into the cue hole 3, lifted upward and opened, and a hook with a hook is inserted into the cue hole 3. The slats 2 are lowered and closed by hooking. In both cases of automatic and manual operations, both ends of the slat 2 move up and down along the grooves of the frames 1a and 1b, so that the operation is performed extremely smoothly. A composite film 4 made of a special material is adhered to the back surface of the slat 2 as shown in FIG.

Select one of the composite membrane 4, ie, GORE-TEX (trade name of Japan Gore-Tex Corporation) or MICRO-TEX (trade name of Nitto Denko Corporation) or the like. The most distinctive feature of Gore-Tex among the composite membranes 4 made of special materials is an extremely thin membrane in which two types of special resin material layers are compounded. It is a film made by specially stretching polytetrachloroethylene (PTFE), and the other side is a special polymer that blocks pollutants such as oil, and is formed by combining the two. The specially stretched PTFE has 1.4 billion extremely fine holes (0.2 micron) in 1 cm ² ,
One pore size is (5,000-20,000) smaller than a water droplet, which is much smaller than a water droplet, but larger than a water vapor molecule (700 times the size of a water vapor molecule). Because of this property, it has a property of allowing water vapor to pass but not water, and not allowing air or pollutants to pass. As a result, it shuts out the wind, prevents the penetration of contaminants such as oils, cosmetics, insect repellents, detergents, foods, etc., enhances waterproofness, hardly changes moisture permeability, and retains excellent stain resistance. ing. GORE-TEX® membrane composite structure prevents clogging by contaminants and maintains excellent waterproof, breathable and windproof properties over a long period of time, and has excellent durability even after repeated washing. is there.

A microtex or the like having the same quality as Gore-Tex is also used as a reinforcing member of the shutter in the same manner as Gore-Tex.

Although it does not matter which of the above two materials is used,
When the synthetic resin is used, it is lightweight, prevents noise when the shutter is moved up and down, can operate the shutter smoothly without wear due to friction, and has the effect of improving the strength of the shutter.

The composite film 4 which is a thin piece is adhered to the back surface of the shutter, and the slats 2 and the adjacent slats 2 are swelled at each of the locking portions 5 which lock the slats 2 to form a swelling portion 6. ing. Then, a shutter slidably supported in the grooves of the frame bodies 1a and 1b is wound on a winding drum 8 via a guide roll 7, or is fed out to open and close an entrance or a window.

In the embodiment shown in FIG. 3, the composite film 4 described with reference to FIG. 2 is adhered to the back surface of the shutter. The difference from FIG. Part 6
Is not formed.

In the embodiment shown in FIG. 4, the composite membrane 4 is adhered along the back surface of each locking portion 5 of the plurality of slats 2. When formed in this manner, the composite film 4 made of a special material is not required on the entire back surface of the shutter. In addition, the composite film 4 is stuck along the locking portions 5 in a strip shape, so that attachment is extremely easy. .

In the embodiments shown in FIGS. 2 to 4 described above, the composite film is adhered to the back surface of the shutter. However, the composite film is adhered to the shutter surface in the same configuration. Is also included.

In the embodiment shown in FIG. 5, composite films 4 and 4 made of a special material are adhered to the entire surface of the front and back surfaces of the shutter in a sandwich shape. When formed in this manner, winding and unwinding of the shutter are smoothly performed.

The embodiment shown in FIG.
The bulging portion 6 is formed on the surface of the locking portion 5 and the bulging portion 6 is not formed on the back surface of the locking portion 5.

In the embodiment shown in FIG. 5, the composite film is stuck on the front and back surfaces of the shutter, and the bulging portions are formed on both the front and back surfaces of the locking portion. In the embodiments described above, the bulging portion is formed only on the front surface of the locking portion. However, the present invention provides a case where no bulging portion is formed on the front and back surfaces of the locking portion and a case where the bulging portion is formed only on the back surface of the locking portion. The case where the protruding portion is formed and the bulging portion is not formed on the surface of the locking portion is also included. In addition, when the composite film is not attached to the entire front and back surfaces of the shutter, but is attached only to the front and back surfaces of the locking portion, the configuration of the bulging portion is formed on both the front and back surfaces of the locking portion, or is formed on either one side It is conceivable that a composite film is not formed on both sides, or a composite film is alternately attached to the front and back of the locking portion.

[0024]

Since the present invention is configured as described above, it has the following effects.

Since a composite film made of a special material is attached to the shutter and used, water, wind, and humidity can be prevented from entering from the locking portion of the shutter by the composite film. Has an effect of preventing a failure of the corrosive member or the like and maintaining durability.

Since the composite film is formed so as to bulge so as to form a space between the locking portion and the composite film, it flexibly bends and expands when the shutter is moved in and out, the operation is extremely good, and the locking portion is formed by the composite film. Even if the film is indirectly contacted with the frame by the film, there is no damage due to frictional resistance, and the noise of metal noise is prevented before going up and down, and there is an effect that the reinforcing force of the shutter is increased.

When the composite film is adhered to the front and back surfaces of the shutter, the waterproofness, windproofness, and moisture permeability from the locking portion are increased, and there is an effect that the shutter can be smoothly wound and extended.
