Description

  TECHNICAL FIELD The present invention relates to a hook-and-loop fastener and a filter structure, and more particularly, to a hook-and-loop fastener used for attaching a filter that is fixed to the outer surface of a screen door frame and covers the entire screen of the screen door, and a filter for preventing contamination of the screen door. The present invention relates to an attached filter structure.

  2. Description of the Related Art Conventionally, there is a screen door filter cover that is detachably attached to a screen door in order to prevent the screen door installed on a house window from being soiled.

  FIG. 6 is a perspective view showing an external appearance of a conventional screen door filter cover disclosed in Patent Document 1. As shown in FIG.

  Referring to the drawing, first, the screen door 74 is provided in a window of a house (not shown), and its periphery is fixed by a frame body 75. The frame body 75 is made of, for example, aluminum and is a rectangular frame with a stable shape in front view. A surface bonding fastener 73a is provided on the entire periphery of the surface (outer surface) facing the screen door filter cover 71 described later. It is attached. The surface bonding fastener 73a is not particularly limited as long as it can be easily attached and detached in surface bonding with the surface bonding fastener 73b described later.

  Next, the screen filter cover 71 is mainly composed of a breathable material 72 and a surface bonding fastener 73b. The breathable material 72 is a filter made of, for example, a non-woven fabric, and is excellent in breathability and difficult to pass dust and dirt. A surface bonding fastener 73b is attached to the periphery of the surface of the screen door filter cover 71 facing the screen door 74 at a position corresponding to the surface bonding fastener 73a. One of the surface bonding fasteners 73a and 73b has a male engagement element, and the other has a female engagement element. Therefore, as shown by the arrow drawn with the dashed-dotted line of a figure, it can attach by pressing the screen door filter cover 71 against the screen door 74. FIG.

  As a method of attaching the filter to the screen door, in addition to the above embodiment using two types of surface bonding fasteners, a method in which a double-sided adhesive tape is applied to the periphery of the filter, a pin-like member is inserted into the screen door screen, and the filter is fixed. There are those that attach a filter by sandwiching a foam material in the end face of the screen door frame (the part that sandwiches the rail), and those that attach the filter using a rubber frame to which the screen door net is attached.

  By attaching the screen filter cover to the screen door in this way, fine dust, dust, insect carcasses and the like are prevented from entering the room from the screen screen while maintaining air permeability.

Registered Utility Model No. 3034455

  In the conventional screen door filter cover described above, in order to achieve the purpose of preventing the screen door from being soiled, it is necessary that the filter is always attached to the screen door when the screen door is used.

  However, here, when a person opens the door inward to enter the room, a strong wind from the indoor side to the outdoor side is generated, and the strong wind from the indoor side may hit the screen door. At this time, in the conventional screen door filter cover, the filter attached to the screen door directly collides with the strong wind, and the air pressure caused by the strong wind cannot be released from the screen door to which the filter is attached. The problem was that the entire screen door was inadvertently detached from the window frame without the filter being peeled off by air pressure. Patent Document 1 discloses other embodiments such as a surface bonding fastener or the like provided on a part rather than the entire periphery of the frame body, but a screen door from the viewpoint of solving the above problem. There is no specific aspect of the filter cover in the prior art.

  Further, in the case where a double-sided adhesive tape is applied to the periphery of the filter, there is a problem that the adhesive strength is remarkably reduced and the filter is peeled off when wet from rain or the like.

  Further, in the case of fixing the filter by inserting a pin-like member into the screen body of the screen door, there is a problem that the filter and the screen door may be broken when continuously used in an environment where wind from the indoor side is generated. .

  In addition, if the filter is attached by sandwiching foam material between the screen door frame end (the part where the rail is sandwiched) or the filter is attached using the rubber frame with the mesh of the screen door, remove the screen door once. The installation method was not easy, such as having to install a filter.

  The present invention has been made to solve the above-described problems, and includes a hook-and-loop fastener that can always stably attach a filter to a screen door during normal use of the screen door, including a case where the screen door is wet. It is an object of the present invention to provide a filter structure that can be easily constructed with little risk of the screen door being inadvertently detached from the window frame when a strong wind is generated from the inside.

  In order to achieve the above object, the invention according to claim 1 is a hook-and-loop fastener used for attaching a filter made of a non-woven fabric that is fixed to the outer surface of the screen door frame and covers the entire screen door screen.

  Invention of Claim 3 is a filter structure, Comprising: A screen door attached to a window frame, a plurality of hook-and-loop fasteners affixed to the outer surface of the screen door frame at predetermined intervals, and attached via a hook-and-loop fastener And a filter made of non-woven fabric covering the entire outer surface of the screen door, and when the air pressure applied to the filter from the screen door increases to a specific amount, the screen door is positioned between each of the adjacent hook-and-loop fasteners before coming off the window frame. The predetermined interval is set so that the filter portion is bent by a predetermined amount of floating width to suppress the action of air pressure.

  If comprised in this way, the force added to the screen door by the increase in the air pressure from the room side will be reduced.

  According to a fourth aspect of the invention, in the configuration of the third aspect of the invention, the minimum value of the predetermined interval is set such that the floating width is 5 mm or more when a specific amount of air pressure is applied.

  If comprised in this way, air will be discharged | emitted from the bent part of a filter.

  According to a fifth aspect of the invention, in the configuration of the fourth aspect of the invention, the maximum value of the predetermined interval is set such that the floating width is 40 mm or less when a specific amount of air pressure is applied.

Can be reduced.

It is a schematic front view which shows the whole structure of the filter structure by embodiment of this invention. FIG. 2 is an enlarged schematic perspective view of an X portion shown in FIG. 1. It is an expansion schematic sectional drawing of the III-III line shown in FIG. It is a schematic perspective view which shows the mode of Example 1 by the filter structure of this invention. It is a schematic front view which shows the mode of Example 2 and Example 3 by the filter structure of this invention, Comprising: (1) is a thing with a comparatively large space | interval, (2) is a thing with a comparatively small space | interval. It is. It is a perspective view which shows the external appearance of the conventional screen door filter cover.

  FIG. 1 is a schematic front view showing the overall structure of a filter structure according to an embodiment of the present invention. FIG. 2 is an enlarged schematic perspective view of a portion X shown in FIG.

  First, referring to FIG. 1, a filter structure 1 includes a screen door 4 attached to a window frame of a house (not shown), and a plurality of hook-and-loop fasteners 3 attached to an outer surface of a frame body 5 of the screen door 4 at a predetermined interval. And a filter 2 made of a nonwoven fabric that is attached via a hook-and-loop fastener 3 and covers the entire outer surface of the screen door 4.

The filter 2 is, for example, a non-woven fabric of polyester fiber, and has approximately the same size as the outer extension of the frame 5 of the screen door 4 to be attached. The air flow rate in the JIS L 1096 A method (fragile type method) (cc / cm ² · sec) Is preferably 800 or more and 3500 or less. If the air flow rate is within the above range, it is possible to achieve both a filter effect for preventing dirt on the screen door and an appropriate bending effect against strong winds while maintaining air permeability.

  Moreover, the manufacturing method of the filter 2 is more preferably a cross web than a parallel one. The cross web is relatively high in durability when the filter 2 is attached to and detached from the hook-and-loop fastener 3 a plurality of times.

  Since the screen door 4 and the frame body 5 are the same as the screen door 74 and the frame body 75 shown in FIG. 6, description thereof will not be repeated. The screen door uses a standard 18 mesh.

  Next, referring to FIG. 2, the hook-and-loop fastener 3 is provided on one side of the base body 8 on which a large number of male engagement elements 9 to which the filter 2 is attached are formed, and on the other side of the base body 8. A smooth sheet 11 fixed via the first high weather-resistant pressure-sensitive adhesive 10 and a second high weather resistance applied to the entire surface of the sheet 11 opposite to the surface fixed to the base body 8. It is comprised from the adhesive 12.

  The base body 8 is made of, for example, polyester and has, for example, a rectangular sheet shape with a length of 10 mm and a width of 20 mm.

  The male engagement element 9 is, for example, a bowl shape and engages with the filter 2. This engagement is physical and does not weaken even when the filter 2 and the male engagement element 9 are wet due to rain or the like.

  The high weather-resistant pressure-sensitive adhesives 10 and 12 are acrylic pressure-sensitive adhesives, for example, and hardly cause quality deterioration such as deformation and alteration even when used outdoors. Further, the adhesive strength allows the hook-and-loop fastener 3 to be easily attached to and detached from the frame 5 by a human hand. The first high weathering pressure-sensitive adhesive 10 preferably has higher adhesive strength than the second high weathering pressure-sensitive adhesive 12. If it is so, when attaching and detaching the hook-and-loop fastener 3 with respect to the frame body 5, a possibility that the base body 8 and the sheet | seat 11 will peel carelessly reduces.

  The sheet 11 is made of, for example, polyethylene terephthalate (PET), and has a higher rigidity and a smooth shape than the base body 8, so that the adhesion to the outer surface of the smooth frame body 5 is increased. The stability of the mounting state is improved and the usability during handling is improved. Further, by making the seat 11 slightly larger than the base body 8, the positioning of the base body 8 with respect to the seat 11 is facilitated, and the stability of the mounting state of the hook-and-loop fastener 3 is further improved.

  The hook-and-loop fastener 3 configured as described above does not weaken the engagement with the filter 2 even when wetted by rain or the like, and the stability of the attached state is improved.

  Next, referring back to FIG. 1, a plurality of hook-and-loop fasteners 3 are attached to the outer surface of the frame 5 at predetermined intervals. Here, the interval means the shortest distance in the direction parallel to the direction in which the frame 5 of the screen door 4 runs at the end of each of the adjacent surface fasteners. The predetermined interval means an interval within a predetermined range described later. When strong wind from the indoor side (screen door side) hits the filter structure 1 between the adjacent hook-and-loop fasteners, the filter 2 is bent outward to generate a floating width. Part is discharged. In addition, when adjacent surface fasteners are extremely close to each other, it is assumed that there is no interval and the surface fasteners are continuous.

  Here, the floating width will be described.

  FIG. 3 is an enlarged schematic cross-sectional view taken along the line III-III shown in FIG. 1 and shows a state in which strong wind from the indoor side is hit.

  With reference to the figure, the filter 2 bends outward except for the portion engaged with the hook-and-loop fastener 3 by the strong wind from the indoor side as indicated by the arrow. At this time, the maximum distance (H in the figure) in the vertical direction from the frame body 5 of the bent portion is the filter's floating width with respect to the state in which the normal filter 2 is attached as shown by the one-dot chain line. .

  And the float of a filter becomes large, so that the space | interval of a hook_and_loop | surface fastener is large. Therefore, in order to solve the problem of the filter structure 1 corresponding to the strong wind, the set predetermined interval is important.

  When the distance between the adjacent surface fasteners is less than 0.5 cm at the closest distance, the filter 2 has a floating width of less than 5 mm when the strong wind from the indoor side hits the filter structure 1, and the wind is The screen door 4 is difficult to be discharged from the floating width and directly collides with the filter 2, so that the screen door 4 may be carelessly detached from the window frame. In addition, if the surface fasteners adjacent to each other are more than 75 cm at the farthest point as the maximum value, after the strong wind from the indoor side hits the filter structure 1, the float width of the filter 2 exceeds 40 mm and the strong wind disappears. Deflection remains in the filter 2, and outside air directly enters from the gap of the deflection, and the filter effect is deteriorated.

  Therefore, it is preferable that the predetermined interval has a minimum value of 0.5 cm and a maximum value of 75 cm. If the predetermined interval is set within the above range, the filter 2 bends outside the engagement portion with the surface fastener 3 with respect to the specific amount of air pressure, and air is discharged from the bent portion. The increase in air pressure with respect to the filter 2 can be mitigated. Further, since the amount of air passing between the filter 2 and the frame body 5 is limited, the filter effect can be maintained without the bending of the filter 2 remaining.

  In the filter structure 1 according to this embodiment, when the air pressure applied to the filter 2 from the screen door 4 side increases to a specific amount, before the screen door 4 comes off the window frame, between the adjacent surface fasteners 3. The predetermined interval is set so that the portion of the filter 2 that is positioned is bent by a predetermined amount of floating width to suppress the action of air pressure. As a result, the force applied to the screen door due to an increase in air pressure from the indoor side is reduced, so that the risk of the screen door being inadvertently detached from the window frame is reduced. In addition, the specific amount means that the wind from the indoor side is strong enough to remove the screen door from the window frame in the case of a conventional screen door filter cover (with the filter fixed around the entire periphery of the screen door frame). It means the amount of air pressure applied to the filter 2 when hitting 1. Also, the predetermined amount of floating width of the filter 2 is the floating width of the portion of the filter 2 located between each of the hook-and-loop fasteners 3 when a specific amount of air pressure is applied to the filter 2 from the screen door 4 side as described above. And is determined mainly by the interval between the hook-and-loop fasteners 3.

  Next, a method for constructing the filter structure 1 will be described.

  First, the hook-and-loop fastener 3 is attached to the four corners of the outer surface of the frame 5 of the screen door 4 with the high weather-resistant adhesive 12. Next, each of the hook-and-loop fasteners 3 is pasted at the predetermined interval. And the filter structure 1 can be simply comprised by attaching the filter 2 with the male type | mold engagement element 9 of the surface fastener 3 so that the outer surface whole surface of the screen door 4 may be covered.

  In the filter structure 1 configured as described above, since the filter 2 is attached by the hook-and-loop fastener 3, the stability of the attachment state of the filter 2 is improved even when wet in the rain. In addition, when strong wind is generated from the indoor side, the filter 2 is bent and the air is discharged, so that the possibility that the screen door 4 is inadvertently detached from the window frame is reduced.

  In the above embodiment, the filter is made of polyester fiber, but may be made of other materials. For example, rayon, acrylic, PET, or a mixed material thereof can be used.

  In the above embodiment, the hook-and-loop fastener is composed of the male engagement element, the base body, the first high weather resistance adhesive, the sheet, and the second high weather resistance adhesive. Even if it is composed of an element, a base body and a highly weather-resistant adhesive, the stability of the filter mounting state when wet with rain is improved.

  Further, in the above embodiment, the sheet is made of PET, but may be made of other materials. The sheet is slightly larger than the base body, but may be approximately the same size as the base body or smaller than the base body.

  Furthermore, in the above embodiment, the high weather-resistant pressure-sensitive adhesive is an acrylic pressure-sensitive adhesive, but any other material can be used as long as it adheres easily by hand pressing and does not peel off when a specific amount of air pressure is applied to the filter. It may be made of any material.

  Furthermore, in the above embodiment, the hook-and-loop fastener has a rectangular sheet shape with a length of 10 mm and a width of 20 mm, but may have other sizes or other shapes. For example, a circular sheet shape having a diameter of 10 mm can be mentioned.

  Further, in the above-described embodiment, the high weather resistance adhesive is applied to all of the specific surfaces of the base body and the sheet, but the high weather resistance adhesive may be partially applied.

  Further, in the above embodiment, the male engagement element is a saddle type, but other shapes may be used. For example, an arrowhead type and a mushroom type are mentioned.

  Furthermore, in the above-described embodiment, the plurality of hook-and-loop fasteners are attached at equal intervals, but may not be at equal intervals. That is, each of the intervals may be within a predetermined range.

  Furthermore, in the above embodiment, a specific surface fastener is used for the filter structure, but another surface fastener may be used.

  Further, in the above-described embodiment, the 18-mesh standard product is used as the screen door, but other mesh screen doors can be similarly applied in consideration of the ventilation resistance.

  Furthermore, in the above embodiment, a specific filter is used, but other filters may be used. In that case, since the flexural rigidity changes depending on the material, basis weight, etc. of the filter, the same effect can be obtained if a predetermined interval is set so as to ensure the same floating width.

  Hereinafter, the filter structure according to the present invention will be specifically described. In addition, this invention is not limited to the Example ([Examples 1-3]) shown below.

  FIG. 4 is a schematic perspective view showing the state of [Example 1] by the filter structure of the present invention.

  Referring to the drawing, the size of the frame 5 of the screen door 4 of the filter structure 1 is 180 cm in the vertical direction (longitudinal direction) and 90 cm in the horizontal direction (short direction). On the inner surface (the surface opposite to the direction in which the filter 2 is pasted), plastic cardboard partition plates 15a and 15b (vertical 180 cm, horizontal 90 cm, thickness 4 mm) are placed one by one on the right and left, The partition plate 15c (length 45cm, 90cm) was installed so that it might span two sheets. The partition plate 15 and the filter structure, and the partition plates 15 were fixed using vinyl tape.

  In the filter structure 1, four types of examples (Examples 1-1 and 1-2 and Comparative Examples 1-1 and 1-2) in which the configuration for attaching the filter 2 is changed are prepared. Experiments A to D were performed in which the fixing force of the filter was measured by applying wind under four conditions.

  The mounting structure of the four types of filter structures used in each experiment is shown in the following table.

表１に示す通り、実施例１−１は、ベース体の一方面に形成された鉤型の雄型係合素子によってフィルターと係合され、ベース体の他方面に塗布されたアクリル系粘着剤によって網戸の枠体に貼着される面ファスナーを用いたものである。この面ファスナーの大きさは、枠体の長手方向を縦として、縦１０ｍｍ、横２０ｍｍである。この面ファスナーを、枠体の四隅と、枠体の外方面の長手方向に５個（各４５ｃｍ間隔）、短手方向に３個（各４５ｃｍ間隔）存在するように全周に貼り付け（計１２個）、この上にフィルターを取り付けることで実施例１−１のフィルター構造体を構成した。

As shown in Table 1, Example 1-1 is an acrylic pressure-sensitive adhesive that is engaged with a filter by a hook-shaped male engagement element formed on one surface of a base body and applied to the other surface of the base body. A hook-and-loop fastener attached to the frame of the screen door is used. The size of the hook-and-loop fastener is 10 mm in length and 20 mm in width with the longitudinal direction of the frame body as the length. This hook-and-loop fastener is affixed to the entire circumference so that there are five (45 cm each) in the longitudinal direction of the four corners of the frame and the outer surface of the frame (each 45 cm apart) and three in the short direction (45 cm each). 12), a filter structure of Example 1-1 was configured by attaching a filter thereon.

  In Example 1-2, the filter is engaged by a hook-shaped male engagement element formed on one surface of the base body, and is fixed to a smooth sheet by an acrylic adhesive applied to the other surface of the base body. Then, a hook-and-loop fastener that is attached to the frame of the screen door by an acrylic pressure-sensitive adhesive applied to the surface of the smooth sheet opposite to the direction in which the base body exists is used. The size of the hook-and-loop fastener and the installation interval were the same as in Example 1-1, and the filter structure of Example 1-2 was configured.

  In Comparative Example 1-1, the filter structure is configured by being attached to the frame of the screen door with a urethane-based adhesive applied to the entire periphery of the peripheral edge of one side of the filter.

  Comparative Example 1-2 uses a smooth sheet with an acrylic adhesive applied on both sides. It is affixed to the filter on one side of the sheet and affixed to the screen door frame on the other side. The filter structure of Comparative Example 1-2 was configured by attaching the sheet to the entire periphery of the outer periphery of the frame and attaching the filter.

A filter having an air flow rate (cc / cm ² · sec) of 808 in each experiment was used.

In Experiments A to D, a fan “100 cm big fan” (part number: BF-100V) manufactured by Nakatomi Co., Ltd. was used. A wind having a wind speed of 171 m / min and an air volume of 516 m ³ / min was generated 1 m away from the filter structure in each direction shown in FIG. 4, and the wind was applied to the filter structure for 1 minute.

  In Experiment A, with the filter dried, wind was applied from the screen door side of the filter structure as indicated by arrows (A, D) shown in FIG. This is the state when the air pressure applied to the filter from the screen door side has increased to a specific amount, that is, if the screen door filter cover is conventional (the filter is fixed all around the screen door frame) Corresponds to wind from the indoor side with such a strong strength.

  In Experiment B, with the filter dried, wind was applied from the left and right sides of the filter structure as indicated by the arrows in FIG. 4 (B).

  In Experiment C, with the filter dried, wind was applied from the filter side of the filter structure as indicated by the arrow in (C) of FIG.

  In Experiment D, water is sprayed from outside on the entire periphery of the filter so that the filter is wet. As shown by the arrows (A, D) shown in FIG. Wind was applied from the side. This corresponds to a state when the air pressure applied to the filter from the screen door side increases to a specific amount when the filter structure is wet with rain.

  The results are shown in the table below.

尚、表データ中の○はフィルターが剥がれなかったことを示し、×はフィルターの一部に剥がれが生じたことを示す。又、総合評価中の○は実験Ａ〜Ｄの全てにおいてフィルターが剥がれず優秀であったことを示し、×は実験Ａ〜Ｄのいずれかにおいてフィルターに剥がれが生じ不適であったことを示す。

In the table data, “◯” indicates that the filter was not peeled off, and “X” indicates that a part of the filter was peeled off. Moreover, (circle) in comprehensive evaluation shows that the filter did not peel in all the experiments AD, and it was excellent, and x shows that the filter peeled off in any of the experiments AD, and was unsuitable.

  As shown in Table 2, in Example 1-1 and Example 1-2 (using the surface fasteners of each configuration), the screen includes a wet state of the filter (corresponding to a wet state of rain). It was found that the filter does not peel off even with strong winds from the side (inside the room).

  FIG. 5 (1) is a schematic front view showing a state of [Example 2] by the filter structure of the present invention.

  In [Example 2], eight types of conditions (Examples 2-1 to 2-3, Comparative Example 2-1 and Reference Examples 2-1 to 2-4) for the combination of the type of filter and the number of hook-and-loop fasteners are prepared. Then, the preferred conditions for the strong wind from the indoor side were examined.

  The filters in each example are as shown in the following table.

尚、材質について、実施例２−１〜２−３、比較例２−１及び参考例２−１、２−２は、ポリエステル繊維からなる不織布である。参考例２−３は、レーヨン及びアクリルからなる不織布である。参考例２−４は、ＰＥＴとポリエチレンの混合不織布である。

Regarding materials, Examples 2-1 to 2-3, Comparative Example 2-1, and Reference Examples 2-1 and 2-2 are nonwoven fabrics made of polyester fibers. Reference Example 2-3 is a nonwoven fabric made of rayon and acrylic. Reference Example 2-4 is a mixed nonwoven fabric of PET and polyethylene.

  The screen door, the frame, and the hook-and-loop fastener used the same thing as Example 1-2 in [Example 1].

  A strong wind from the screen door was applied to the filter structure in each example under the same conditions as in Experiment A of [Example 1].

  The conditions and results for each example are shown in the table below.

面ファスナーの個数は、枠体の長手方向の一方における面ファスナーの個数を示す。５個の場合は、枠体の長手方向に５個（各４５ｃｍ間隔）、短手方向に３個（各４５ｃｍ）設置した。４個の場合は、図５の（１）に示すように、枠体の長手方向に４個（約５０ｃｍ、７５ｃｍ及び約５０ｃｍ間隔）、短手方向に３個（各４５ｃｍ間隔）設置した。即ち、複数の面ファスナー同士の間隔の最大値は図のＷ_１で示す部分であり７５ｃｍであった。３個の場合は、枠体の長手方向に３個（各９０ｃｍ間隔）、短手方向に３個（各４５ｃｍ間隔）設置した。

The number of hook-and-loop fasteners indicates the number of hook-and-loop fasteners on one side in the longitudinal direction of the frame. In the case of five, five (45 cm each) were installed in the longitudinal direction of the frame, and three (45 cm each) in the short direction. In the case of four, as shown in (1) of FIG. 5, four (about 50 cm, 75 cm, and about 50 cm intervals) were installed in the longitudinal direction of the frame, and three (45 cm each) were installed in the short direction. That is, the maximum value of a plurality of surface fasteners each other spacing of 75cm and a portion shown by W ₁ in FIG. In the case of three, three (each 90 cm interval) were installed in the longitudinal direction of the frame, and three (45 cm each) were installed in the short direction.

  The floating width (mm) is the maximum of the floating widths of the respective filters at the interval between the surface fasteners when the strong wind from the screen door is applied.

  In the evaluation of the floating width, ○ is that the screen door is not likely to come off the partition plate (corresponding to the window frame) due to air being discharged from the bent part of the filter, and the bending remains even after the strong wind is stopped Since the outside air directly enters through the gap of the bending, the case where the filter effect has deteriorated is indicated as x.

  The durability of attachment / removal was evaluated as ○ when the surface fastener was attached to and removed from the filter a plurality of times, and ○ when the surface of the filter was not torn, and x when the surface fastener was torn.

  From the results shown in Table 4, the float width of the filter greatly changed depending on the number (space) of the hook-and-loop fasteners than the air flow rate of the filter, and the float width became larger as the number of hook-and-loop fasteners (the gap was larger). .

  Further, if the interval was 75 cm (Example 2-2) or less, the floating width was 40 mm or less, and no residual bending occurred.

  Furthermore, the durability of attachment and removal was better for the cross web than for the parallel web.

  Furthermore, Reference Examples 2-1 to 2-4 are excellent in evaluating the floating width.

  An experiment was conducted to examine the effect of the spacing between the plurality of hook-and-loop fasteners on the discharge of air and the remaining deflection.

  FIG. 5 is a schematic front view showing a state of [Embodiment 3] by the filter structure of the present invention, and (2) shows 100 hook-and-loop fasteners.

  In this example, the screen door and the frame body were 200 cm long (longitudinal direction) and 90 cm wide (short direction).

  The hook-and-loop fastener used was the same as in Example 1-2 in [Example 1].

  The same filter as in Example 2-1 in [Example 2] was used.

  A strong wind from the screen door was applied to the filter structure in each example under the same conditions as in Experiment A of [Example 1].

  The conditions and results in each example are shown in the following table.

面ファスナーの個数は、枠体の長手方向の一方における面ファスナーの個数を示す。［実施例３］においては、面ファスナーは長手方向と短手方向において共に一定間隔に設置した。即ち、複数の面ファスナーの各々の間隔を示す間隔（ｃｍ）は、面ファスナーの個数に対応しており、表中の数字となる。

The number of hook-and-loop fasteners indicates the number of hook-and-loop fasteners on one side in the longitudinal direction of the frame. In [Example 3], the hook-and-loop fasteners were installed at regular intervals in both the long and short directions. That is, the interval (cm) indicating the interval between the plurality of hook-and-loop fasteners corresponds to the number of hook-and-loop fasteners, and is a number in the table.

  The wind was discharged from the bent part of the filter with respect to the wind from the screen door side.

  As for the remaining deflection, the case where the deflection did not remain on the filter after the wind was stopped was indicated as ◯, and the case where the deflection remained was indicated as x.

  From the results of Table 5, if the distance is 0.5 cm or more and 65.3 cm or less, air is discharged from the bent part of the filter against strong wind, and the possibility that the screen door is detached from the partition plate (window frame) is reduced. Further, it has been found that no residual bending occurs and deterioration of the filter effect can be prevented. In [Example 2], it is known that the same effect can be obtained even when the interval is 75 cm. Accordingly, the predetermined interval for attaching the plurality of hook-and-loop fasteners may be a minimum value of 0.5 cm and a maximum value of 75 cm.
