Description

  The present invention relates to a shutter, and more specifically, it is a versatile shutter that can be attached to an existing sash or window without processing, and prevents wind and rain, and reduces the daylighting function of a glass window. The present invention relates to a shutter that allows ventilation indoors and outdoors.

  In addition to preventing wind and rain, the shutters are usually used on the most outdoor side of the window frame to prevent crimes and fires, and prevent the window glass and shoji from being damaged by strong winds such as typhoons. The material is often made of a hard material such as a wooden board, a lightweight iron plate, or an aluminum plate for shading, shading, sound insulation, or heat insulation.

  Therefore, when the conventional shutter is closed, the light is blocked, the outside cannot be seen from the room, and the air permeability is shut out. In addition, there exists a screen door as a fitting which has air permeability, and according to the screen door, natural lighting and the visibility to the outdoors can also be ensured, aiming at ventilation | gas_flowing indoors and outdoors. However, the problem remains that wind and rain cannot be prevented only with ordinary screen doors.

  As described above, in the case of wind and rain, the conventional joinery has not been able to prevent indoor entry of wind and rain and ensure indoor and outdoor air permeability while ensuring the same outdoor visibility as a glass window. . As a joinery for solving such a problem, there is a glass louver window that can adjust the angle of the louver by arranging a plurality of glass louvers and turning an operator handle, and has both lighting and air permeability. However, since the glass louver window has a complicated structure, has a large number of parts, and is expensive, in general houses, it is used only for relatively small windows for daylighting and ventilation in some parts of toilets and bathrooms. It is in the present situation. In addition, when it is made of glass, it is easily broken when an impact is applied, and the broken piece may cause injury. But in the present invention. Even if it breaks, it is safe because it doesn't scatter large pieces like glass. .

  In view of the problems of such shutters, various techniques have been proposed in the past. For example, “Transparent or semi-transparent, lightweight, rigid, flat plastic resin shielding plate body has a rectangular shape, and the surface of the shielding plate body is provided with a plurality of elongated straight ventilation holes for introducing outside air and for ventilation. To prevent rain from flowing in, a small plate that acts as an elongate plate-like ridge is installed at the top of the vent hole, does not block the ventilation, is attached obliquely downward to prevent rain inflow, and hooked to hook on the existing screen door outer frame Two hooks are installed at the upper end of the shield plate body, and hooked on the screen door frame outside and at the top end to close the screen door frame. Hook-shaped metal fittings are tightly attached to the upper and lower ends of the coil springs that are installed and expanded as appropriate, and these are inserted into the small holes for adjusting the mounting position of the shield plate body. Technology called. "To fix contact the shielding plate body hook under the bottom of the outer screen door frame pulls down the hook-like fitting in has been proposed (see Patent Document 1). Such a technique shares a common problem with the present invention, and has many common points in its configuration. However, in such a technique, two hook-shaped clasps that are attached to the window outer frame by attaching to the window screen outer frame are installed at the upper end of the shielding plate body wife side, and hooked on the screen door outer side and upper end. Because it is configured to be in close contact with the screen door frame and suspended, it looks like a bay window on the second floor or above without a veranda. Installation on windows that cannot be operated from the outside is difficult and cannot be slid. On the other hand, since the present invention is slidably sandwiched between the upper and lower grooves on the indoor side of the sash frame, it can be easily attached from the indoor side and can slide. Moreover, the point which considers the rigidity by integral molding etc. is also greatly different.

  In addition, a technique relating to “a hooded screen door aluminum sash joinery that prevents rain / snow from entering the room even on days of strong winds, raining or snowstorms by attaching a hood to the screen door” has been proposed (see Patent Document 2). Such a technique also has a common problem to be solved with the present invention, and has many common points in its configuration. However, in such a technique, as in the above-mentioned Patent Document 1, since the attaching means to the window is fixed to the existing screen door outer frame, like a bay window on the second floor or more without a veranda. Installation on a window that cannot be operated from the outdoor side is difficult, and it cannot slide alone. On the other hand, since the present invention is slidably sandwiched between the upper and lower grooves on the indoor side of the sash frame, it can be easily attached from the indoor side and can be slid alone. Moreover, the point which considers the rigidity by integral molding etc. is also greatly different.

  In addition, “a rain door that can be stored and pulled out of the window for protection from wind and rain and crime prevention, and is made of a synthetic resin having translucency and transparency. A technology related to “Amito” has also been proposed (see Patent Document 3). Such a technique also has a common problem in terms of daylighting and the like, and has a common configuration such as the use of a transparent resin. The transparent shutter according to No. 3 is constructed by attaching a transparent resin shutter body made of light-transmitting synthetic resin to, for example, a wooden or aluminum frame, and by making the frame correspond to an existing shutter rail. This is retrofitted to an existing house, etc. Therefore, the structure is more complex than that of the present invention, and the structure of the present invention is not significantly different from that of the present invention which does not secure rigidity with a frame.

Utility Model Registration No. 3170509 Japanese Utility Model S63-25795 Japanese Patent Laid-Open No. 10-339080

  In view of the above problems, the present invention is a highly versatile shutter capable of being mounted on an existing sash or window without processing, and prevents wind and rain, and reduces the daylighting function of a glass window. To provide technology for shutters that allow ventilation indoors and outdoors.

  In order to achieve the above object, the present invention is a shutter that can be attached to an existing sliding window type sash, and the entire shape is integrally formed from a single sheet of a thermoplastic resin sheet having permeability. The thin plate member is formed to have a thickness of 3 mm or less, and a plurality of substantially louver-like protrusions extending in the lateral direction are provided on the indoor side surface of the shutter, In addition, the size of the projecting width of the protruding portion and the thickness of the thin plate material does not exceed the thickness of the window frame of the sliding window of the sash to be used.

Therefore, the integrally formed transparent resin rain door according to claim 1 or 2, wherein the bending strength in the horizontal direction is improved.

  In the present invention, the thin plate member may be made of a resin having a transmittance of 80% or more, and may be an integrally molded transparent resin shutter according to any one of claims 1 to 3. .

  Further, in the present invention, the thin plate member is translucent or made of a resin that shields electromagnetic waves in a region corresponding to visible light. It can also be set as an integrally molded transparent resin shutter.

  Further, in the transparent resin shutter according to the present invention, a coating for shielding ultraviolet rays is applied to the whole, or the plate material contains an ultraviolet absorber. Any one of the integrally formed transparent resin shutters can be used.

In the present invention, the transparent thermoplastic resin may be an acrylic resin (PMMA: Poly Methyl Methacrylate) or polycarbonate.
It can also be set as the integrally-molded transparent resin shutter according to any one of claims 1 to 6, which is either (PC: Polycarbonate) or PET resin (PET: Poly Ethylene Terephthalate). .

  In order to adjust the indoor environment of the building, the introduction of natural light from the outside is indispensable for maintaining the indoor hygienic environment. However, according to the integrally formed transparent resin shutter according to the present invention, the thermoplastic having transparency is used. Since the resin is used, there is an excellent effect that the light of the glass window can be adjusted for daylighting, and at the same time, indoor and outdoor ventilation is possible. In addition, regarding the transparency, a resin thin plate material having a transmittance of 80% or more is used in claim 4 to enable daylighting substantially the same as that of a window glass. In claim 5, the resin thin plate material is translucent. Since it is made of a resin that shields electromagnetic waves in a region corresponding to visible light, it is possible to obtain a certain degree of daylighting while exhibiting an excellent effect of ensuring privateness.

  In addition, according to the integrally formed transparent resin shutter according to the present invention, it is easy to attach and detach because there is a configuration that uses an existing sliding window type sash groove, and there is no veranda or the like. Even when attached to an existing sash that cannot be operated from the outside, such as a bay window, there is an excellent effect that it is possible to easily attach without installing a scaffold.

  In addition, according to the integrally molded transparent resin shutter according to the present invention, the entire shape is integrally formed from a single sheet material, and furthermore, there are no other components, so productivity is excellent and mass production is possible at low cost. It has an excellent effect of becoming.

  Moreover, according to the integrally molded transparent resin shutter according to the present invention, the overall shape is integrally formed from a single sheet material, and a plurality of substantially louver-shaped protrusions are provided to increase the rigidity, so that the sash is attached to the sash. Also has an excellent effect that it does not fall off due to bending deformation, and in particular, according to the integrally formed transparent resin shutters according to claim 2 and claim 3, the reinforcing ribs and the protruding portions are arranged in phase in the lateral direction. Therefore, an excellent effect is obtained in that higher rigidity can be obtained.

  Further, according to the integrally molded transparent resin shutter according to the present invention, in the attachment means to the sash, the attachment is made removable by sandwiching the upper and lower sides of the shutter in the sliding window type sash groove. It has the means, and there exists an outstanding effect that attachment and removal are easy.

  Also, according to the integrally formed transparent resin shutter according to the present invention, when the window glass is closed, the airtightness is increased, and since a further space is formed between the indoor and the outdoor, the heat insulating performance is improved. As a result, energy saving is achieved by reducing the cost of air conditioning and heating, and an excellent effect of increasing the soundproofing effect and the anti-condensation effect is achieved.

  In addition, in order to prevent rainwater from being blown by the conventional window equipment, it was necessary to close the window or use a shutter. Therefore, particularly in summer, electrical air conditioning equipment such as air conditioners are often used to adjust indoor temperature and humidity, and it can be said that there was a waste of electric energy resources. However, according to the integrally formed transparent resin shutter according to the present invention, it can be used with the window open, and therefore it can ventilate indoors and outdoors. It has excellent effects of high ecology and economy, such as reducing the amount of air-conditioner used and contributing to the effective use of electricity.

  Further, according to the integrally molded transparent resin shutter according to the present invention, rigidity is achieved by integral molding, thereby enabling formation of a thin plate material of 3.0 mm or less with acrylic or polycarbonate. Therefore, for example, even if it is produced in the standard size of MM (meter module), the edge can be easily cut with an acrylic cutter or a normal cutter knife, so the size can be changed between Kanto and Kansai, Even when the frame body is distorted due to sash deformation over time, an excellent effect is obtained in that the shape can be easily corrected to cope with the distortion.

  In addition, if a coating for increasing the transmittance is applied to the entire integrally molded transparent resin shutter according to the present invention, the surface reflection and the like can be reduced, and the transmittance can be increased, and the daylighting property of the glass window is not impaired. The effect can also be demonstrated. The coating is not particularly limited as long as it enhances the transparency. However, when the resin material is polycarbonate, when it receives ultraviolet rays, it causes a chemical reaction and yellows, and the transparency is easily lost. It is desirable to apply an absorbent layer coating. For example, coating with a fluororesin can be considered.

  In addition, according to the transparent resin shutter according to claim 5, a coating for shielding ultraviolet rays is applied to the whole, or the plate material contains an ultraviolet absorber (UVA: Ultra Violet Absorber). In addition to being able to prevent ultraviolet rays from entering, it has an excellent effect of being able to prevent early deterioration. In particular, due to the nature of an article called a shutter, it takes a long time to be exposed to sunlight. Therefore, it is desirable to employ such a configuration because the transparency of a transparent resin product tends to decrease due to deterioration. For the same reason, it is also effective to use a hindered amine light stabilizer (HALS) in combination. This is because radicals generated by ultraviolet rays are captured and the effect of preventing coloring and maintaining gloss is exhibited.

  In addition, according to the integrally formed transparent resin shutter according to the present invention, the type of transparent resin used as a material is not a thermosetting resin but a thermoplastic resin. This eliminates the need for a large number of molds according to the requirements, and makes it possible to reduce the risk and cost of upfront investment. Moreover, according to the said integrally molded transparent resin shutter according to claim 5, by specifying the enumerated resins, depending on the purpose of emphasizing cost, durability, or productivity from the characteristics of each material. The effect that it can be selected is demonstrated.

  In addition, according to the integrally formed transparent resin shutter according to the present invention, although a thin material of 3.0 mm or less is used, since it is integrally formed including the protruding portion, the overall rigidity is high, Even in bad weather conditions that can be said, it is difficult to come off. Therefore, even if it is not used together with a screen door, there is an excellent effect that it is not skipped.

  Further, according to the integrally molded transparent resin shutter according to the present invention, by adjusting the width of the opening within the dimension that can prevent the invasion of insects by suppressing the protrusion width of the protrusion, in the sash window without the screen door, It has an excellent effect of functioning as a substitute for screen doors.

It is attachment state explanatory drawing of the integrally-molded transparent resin rain shutter which concerns on this invention. It is attachment explanatory drawing which shows the example of attachment application of this invention.

  The integrally molded transparent resin shutter 10 according to the present invention is a shutter that can be attached to an existing sash 40, and has a substantially louver-like projecting portion 20 whose longitudinal direction is the lateral direction on the interior X side surface of the shutter. Are provided, and the upper side portion of the projecting portion 20 has an opening portion 21 for ventilating the indoor X and the outdoor Y, and is a transparent thermoplastic resin having a thickness. These entire shapes are formed by integral molding from a single thin plate material 11 of 3 mm or less, and the upper side and lower side of the shutter 10 are located sideways of the outdoor Y-side glass door frame 41 in the sliding window type sash 40. The outdoor Y side glass window frame 41 located on the outdoor Y side of the indoor X side glass door frame body 41 is inserted into the gap 42 of the sash groove for sliding, and is attached and detached. And it is the maximum that sliding door 10 is free to slide It is characterized. Embodiments will be described below with reference to the drawings.

  FIG. 1 is an overall explanatory view of an integrally molded transparent resin shutter 10 according to claim 1. The integrally molded transparent resin shutter 10 is a shutter that can be attached to an existing sash 40, and a plurality of substantially louver-like protrusions 20 extending in the lateral direction are provided on the interior X side of the shutter. . The protrusion 20 is specified in that it protrudes toward the room X side, but the number, size, or shape shown is not particularly limited. However, an opening 21 that is opened to ventilate the room X and the outdoor Y is formed on the upper side of the protrusion 20, and as a forming means in manufacturing, a position that becomes the upper side of the opening 21 Then, the thin plate material 11 is cut, heated to a temperature at which plastic deformation is likely to occur, and molded by stamping or the like.

  Further, the width of the integrally molded transparent resin shutter 10 is a size that is combined with the protruding width H of the substantially louver-shaped protruding portion 20 and the thickness t of the thin plate material 11, but the sliding window of the sash 40 to be used is used. It is necessary that the dimensions are in a range not exceeding the thickness of the window frame. This is to avoid interference with existing shutters and screen doors 50, and because the thickness t of the thin plate material 11 is as thin as 3.0 mm or less, it is embossed with acrylic resin that has an elongation of only 2 to 10%. This is because cracks are likely to occur at the time of molding, and a polycarbonate having an elongation of 60 to 100% and a PET resin having an elongation of 70 to 130% are capable of being molded but become too thin and lack rigidity. .

  Therefore, the opening width of the vent hole 21 is a value obtained by subtracting the thickness t from the protrusion width H. When the sash 40 that does not have the screen door 50 is used for both the function of the rain door and the function of the screen door 50 according to the present invention, the opening width is set to a width that does not allow insects such as mosquitoes and flies to enter. . Further, in the case of such a configuration, it is difficult to ensure rigidity. Therefore, it is desirable to employ the arrangement configuration of the reinforcing rib portion 30 of claim 2 and the protruding portion 20 of claim 3.

  Moreover, the integrally molded transparent resin shutter 10 according to the present invention employs a configuration in which the entire shape is integrally formed from a single sheet 11 of a thermoplastic resin having permeability. The reason why the transparency is an essential requirement for the material in such a configuration is to avoid losing the daylighting property of the general window glass 43. In addition, in claim 4, the resin having the transmittance of 80% or more is limited to the sliding door in which the glass 43 on the indoor X side and the outdoor Y side is slid so as to overlap one side of the sash 40. The transmittance is about 80%, so that the same level of daylighting can be ensured even when the integrally formed transparent resin shutter 10 according to the present invention is disposed next to the transmittance. That is, it is a specific matter for making the configuration in which the brightness of the indoor X and the visibility to the outdoor Y are not lowered as compared with the glass 43. Here, the transmittance of acrylic is about 93%, which exceeds even glass, and the polycarbonate and PET resin are about 90% less, and the lighting performance is excellent.

  Further, in the integrally formed transparent resin shutter 10 according to the present invention, a thermoplastic resin is used as the material, but the reason for excluding the thermosetting resin is to reduce the cost and to reduce the durability due to deterioration. And so on.

  Moreover, in the integrally molded transparent resin shutter 10 according to the present invention, a configuration is adopted in which the entire shape is formed by integral molding from a single sheet material 11 having a thickness t of 3 mm or less. Even if it is a thin and light resin material, by providing a plurality of the substantially louver-shaped protrusions 20, the rigidity becomes high, and even if attached to the sash 40, it exhibits an excellent effect that it does not fall off due to bending deformation, and the raw material and This is because it can be manufactured without requiring any members other than the thin plate material 11.

  In addition, when the integrally formed transparent resin shutter 10 according to the present invention is attached to the sash 40, the upper and lower sides of the present invention can be slid by inserting them into the gap 42 of the sash 40 as shown in FIG. A configuration is adopted in which the upper side and the lower side are sandwiched.

  FIG. 2 is an overall explanatory view of the integrally formed transparent resin shutter 10 according to claim 2. As illustrated in FIG. 2, the reinforcing rib 30 is a reinforcing portion that extends in the vertical direction, such as providing the reinforcing rib portion 30 in the vertical direction between the protruding portions 20 from both sides of the thin plate member 11, and in the horizontal direction. Prevents bending. By adopting such a configuration, both the protruding portion 21 having the longitudinal direction as the longitudinal direction and the reinforcing rib portion 30 having the longitudinal direction as the longitudinal direction are integrally formed, thereby further increasing the overall rigidity and causing the bending. This prevents falling off the sash 40 and flapping when the wind is strong.

  FIG. 3 is an explanatory diagram of the state of use according to the present invention. FIG. 3 does not show a shutter such as an aluminum shutter, and the window glass 43 and the glass door frame 41 on the outdoor Y side are also made of an integrally molded transparent resin. It is omitted to clearly show the arrangement position of the shutter 10. FIG. 3A shows a state in which the screen door 50, the integrally molded transparent resin shutter 10, the window glass window 43 on the outdoor Y side, and the window glass window 43 on the indoor X side are arranged in this order from the outdoor Y to the indoor X. In FIG. 3B, from the outdoor Y toward the indoor X, the screen door 50, the integrally-formed transparent resin shutter 10, the outdoor Y-side window glass window 43, and the indoor X-side window glass window 43 are arranged in this order. Indicates the state. Further, in FIG. 3, the rainwater S is prevented from entering the indoor X even during wind and rain, and the ventilation air Z that has passed through the mesh of the screen door 50 flows into the indoor X from the opening 21 and can take in outside air. Show. Although there is no room for explanation, the ventilation direction is not limited to this, and ventilation is performed from the indoor X side to the outdoor Y side.

  FIG. 4 is an explanatory view of attachment for attaching the integrally formed transparent resin shutter 10 according to the present invention to the sash 40. The outdoor Y-side glass window frame 42 located on the outdoor Y side of the indoor X-side glass door frame 41 and at the lateral position of the outdoor Y-side glass door frame 41 in the sliding window sash 40 is provided. The upper and lower sides of the present invention can be detachably attached to the sash groove 42 for sliding. 4A shows a state where the outdoor Y side glass door frame 41 is attached to the gap 42 of the sash groove between the slide rail of the glass door frame 41 and the guide rail of the screen door, and FIG. 4B shows the glass on the outdoor Y side. The state attached to the clearance 42 of the sash groove between the slide rail of the door frame body 41 and the slide rail of the glass door frame body 41 of the indoor X side is shown.

  FIG. 5 is another explanatory diagram of the arrangement configuration of the substantially louver-shaped protrusion 20 according to the third aspect. FIG. 5A illustrates an arrangement state in which the positional relationship between the adjacent protrusions 20 is vertically aligned by adopting a three-row configuration in which the protrusions 20 are arranged in the vertical direction. FIG. 5B illustrates an arrangement state in which the positional relationship between the adjacent protrusions 20 is vertically aligned by adopting a two-row configuration in which the protrusions 20 are arranged in the vertical direction. By adopting such a configuration, the bending strength in the horizontal direction is improved, the falling off of the sash 40 due to bending is prevented, and the fluttering due to strong winds and the like is prevented.

  FIG. 6 is an explanatory view of an attached state of the integrally molded transparent resin shutter 10 according to the present invention. As shown in FIG. 6, the present invention is a shutter that can be attached to an existing sash 40, a lateral position of an outdoor Y-side glass door frame 41 in an existing sliding window type sash 40, and Detachment by sandwiching the upper side and lower side of the present invention in the gap 42 of the sash groove for sliding the outdoor Y side glass window frame 41 located on the outdoor Y side of the indoor X side glass door frame 41 Can be attached freely.

  In the integrally molded transparent resin shutter according to claim 4, a resin material having a transmittance of 80% or more is used for the thin plate material 11. By adopting such a configuration, it is possible to perform lighting substantially the same as that of the window glass 43. It is also effective to apply a coating for increasing the transmittance to the whole. If such a configuration is adopted, the daylighting is further enhanced, natural light such as sunlight is taken into the indoor X, contributing to the maintenance of the sanitary environment in the room of the building, and the refraction of light from the residual stress of the deformed portion due to the embossing. It is possible to suppress the visibility from being lowered. Specific types of coating include coating with a fluorine-based resin and a treatment for forming a titanium oxide film.

  In claim 5, the thin plate material 11 is translucent or a resin material that shields electromagnetic waves in a region corresponding to visible light is used. By adopting such a configuration, it is possible to obtain a certain degree of daylighting while ensuring privateness. Specifically, a translucent resin with milky white or a transmitted light control plate (for example, an acrylic plate such as Sumipex (registered trademark)) that can control the transmission amount of light having a specific wavelength in the visible light region is used. It is conceivable.

  According to the sixth aspect, a coating for shielding ultraviolet rays is applied to the whole, or the thin plate material 11 contains an ultraviolet absorber. By adopting such a configuration, it is possible to prevent ultraviolet rays from entering the room and to prevent early deterioration. In particular, due to the nature of an article called a shutter, it takes a long time to be exposed to sunlight. Therefore, it is desirable to employ such a configuration because the transparency of a transparent resin product tends to decrease due to deterioration. Specifically, there are benzotriazole, benzophenone, salicylate, cyanoacrylate, nickel, and triazine types. In particular, benzotriazole ultraviolet absorbers have an absorption range over the entire ultraviolet range. It is desirable to use the benzotriazole-based ultraviolet absorber because it has the best absorption ability. For the same reason, it is also effective to use a hindered amine light stabilizer (HALS) in combination. This is because radicals generated by ultraviolet rays are captured and the effect of preventing coloring and maintaining gloss is exhibited.

  When the thin plate material 11 which is the material of the integrally formed transparent resin shutter 10 according to the present invention is specified as an acrylic resin, the transmittance (90% or more) surpassing that of the glass, high lighting performance and low cost are achieved. In addition, it can be easily processed even when cutting or the like is required. However, since it is weak against impact and easily cracked, an extremely thin material cannot be used, and it is somewhat unsuitable for a large sash 40 such as a 6-scale system or a 9-scale system in the sash 40 standard.

  Moreover, when the thin plate material 11 used as the raw material of the integrally formed transparent resin shutter 10 according to the present invention is specified as polycarbonate, the stretchability is high and the spreadability is good. It can be said that it is a material suitable for. Moreover, the impact strength is ten times as strong as that of the acrylic resin (PMMA), and it is strong and hard to break. However, when it receives ultraviolet rays, it causes a chemical reaction to turn yellow and loses transparency, so that the coating of the ultraviolet absorbing layer and the addition of an ultraviolet absorber as claimed in claim 4 are desirable.

  In addition, when the thin plate material 11 which is the material of the integrally formed transparent resin shutter 10 according to the present invention is specified as a PET resin, the production cost is the largest among the thermoplastic resins, so that the raw material cost can be suppressed. It becomes. In addition, PET resin can be recycled into fiber because of the widespread use of PET bottles, and environmental considerations can be achieved through reuse.

  FIG. 7 is an explanatory view of attachment showing an application example of attachment of the present invention. FIG. 7A shows a case where the upper side and lower side chambers of the integrally formed transparent resin shutter 10 according to the present invention are sandwiched by the gap 42 between the groove on the room X side of the sash 40 and the glass door frame 41. An application example is shown, and FIG. 7B and FIG. 7C are enlarged views in which the respective clamping portions are enlarged separately before and after mounting on the sash 40. Depending on the type of sash 40, there are many cases in which there is a gap 42 for flowing water droplets due to condensation between the angle cover 44 that forms a floor mounting member and the window frame. Therefore, it is also effective to attach the present invention to the gap 42. When installed in such an arrangement, from the outdoor Y to the indoor X, the screen door 50, the outdoor Y side window glass window 43, the indoor X side window glass window 43, and the integrally formed transparent resin shutter 10 are arranged in this order. become.
