Description

  The present invention attaches a case or sheet containing an insecticide, for example, to the screen surface of the screen door, and prevents insects from approaching the screen door with an insecticide attached to the screen door, together with blocking insects from entering the screen door. To attach a case or sheet containing a fragrance to the screen surface of the screen door to give fragrance to the wind coming into the room from the outside, or to decorate the screen surface of the screen door The present invention relates to a fixture used for attaching a decorative article to a screen door to give a pattern to the screen door, that is, for attaching a drug-containing case, a sheet, or a decorative product to the screen surface of the screen door.

  Conventionally, it is known to attach a sheet or case containing an insect repellent to a screen surface of a screen using a hook-and-loop fastener. This attachment method involves attaching one hook-and-loop fastener (for example, a hook-and-loop fastener having a hook-like engagement element) to the insect repellent-containing sheet or the back of the case, pressing it against the screen of the screen door, and the surface opposite to the screen The other hook-and-loop fastener (for example, a hook-and-loop fastener having a loop-like engagement element) is pressed, and both hook-and-loop fasteners are engaged with the mesh face interposed therebetween to attach the insecticide-containing sheet or case to the screen door ( Patent Document 1). Insect repellents for fixing screen doors using such a known technique are now on the market.

  However, in the case of the technique of engaging both hook fasteners with this mesh face sandwiched and fixing to the mesh door, the mesh face existing between the hook hook fastener and the loop hook fastener attached to the back surface of the functional object It is difficult to get both hook-and-loop fasteners close enough because they are blocked, and the engagement force cannot be obtained as expected, and the engagement is released naturally or due to vibrations caused by opening and closing the screen door or vibrations caused by wind. And has the disadvantage that the case falls off.

  More specifically, in order for the hook-and-loop fasteners existing on both sides of the mesh surface to engage, one engaging element passes through the mesh surface of the screen door and reaches the engaging element surface of the other hook-and-loop fastener. However, in the conventional surface fasteners that are generally commercially available, the mesh surface is blocked, and it is difficult for a sufficient number of engagement elements to penetrate the mesh surface, and high engagement force is obtained. I can't get it. If a high engagement force cannot be obtained, a heavy object cannot be attached to the screen surface of the screen door, or even if it is attached, it will be affected by the passage of time or vibration when opening and closing the screen door or glass door. It will happen that the attached object falls off and the attached object falls off.

  Further, as an attachment for attaching an insecticide-containing case or the like to the screen surface of the screen door, it consists of a substrate and a pair of rod-shaped elements protruding from the surface, and the interval between the rod-shaped elements is once widened at the intermediate portion, and the root portion and There is a known attachment that is narrow at the tip or has the opposite interval (Patent Document 2).

  In the case of this fixture, there is no need to clamp the screen door, so there is no problem as in the case of the above-mentioned Patent Document 1, but on the other hand, one of the pair of rod-shaped body elements has sufficient screen surface. When it cannot penetrate, almost no locking force is obtained, and furthermore, a hard, thick and long rod is often used, and it protrudes perpendicularly from the net surface to the tip of the penetrating rod. When the human body comes into contact with the tip, there is a problem that the human body may be damaged in some cases.

In this case, the engaging protrusions are arranged side by side, and the engaging protrusions do not protrude in the engaging element array direction, and the engaging elements have two or more engaging protrusions in the stem height direction. In addition, the protruding lengths of the engaging protrusions of each step protruding from the stem are substantially the same, and the stem width of the stem becomes narrower at each step where the engaging protrusion exists as it goes from the substrate surface to the topmost part. Is the case.

Preferably, in the mounting tool for mounting the object described above, the distance (Z) between the engaging projections in the stem height direction is 0.2 to 1.5 mm, and each stage protruding from the stem The protrusion length (S1) of the engagement protrusion is 0.05 to 0.3 mm, and the height (H) of the stem is 1.0 to 3.5 mm. The stem width (D1) of the portion where the engaging protrusion is present is 0.3 to 0.7 mm, and the stem width of the portion where the second and subsequent engaging protrusions is present is smaller than the stem width immediately below. This is a case where it is narrowed by 0.05 to 0.2 mm, and a case where engaging elements are present at a density of 10 to 40 pieces / cm ² .

  And this invention is the said fixture which is a functional object which consists of a case or a sheet | seat in which the object attached to a mesh surface contains at least any one of an insect repellent, a deodorizing agent, and a fragrance | flavor, In the above attachment, the object attached to the mesh surface is a functional object made of a decorative sheet or a decorative device.

It is the figure which looked at another suitable example of the engagement element which comprises the screen door fixture of this invention from the X direction shown in FIG.

Next, the present invention will be described with reference to the drawings.
As shown in FIG. 1, the screen door fixture of the present invention comprises a substrate (1) made of a thermoplastic resin and a plurality of engaging elements (2) made of the same resin projecting on the surface thereof. The thickness of the substrate (1) is preferably 0.1 to 1.0 mm.

  Examples of the thermoplastic resin forming the substrate and the engaging element include polyolefin resins such as polyethylene and polypropylene, nylon resins such as nylon 6 and nylon 66, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, and polylactic acid, ethylene -A stretchable resin such as a vinyl alcohol copolymer is a suitable example.

  As shown in FIG. 1, the engaging element (2) includes a stem protruding from the substrate surface, an engaging protrusion protruding from the stem to the side, and present in a plurality of stages along the stem height direction. Preferably, as shown in FIG. 1, a large number of engagement elements are formed on the substrate (1) in a direction intersecting with the direction in which the engagement protrusions of the engagement elements protrude (X direction in FIG. 1). Are arranged in parallel, and there are a plurality of such engagement element rows in parallel on the substrate (two rows in FIG. 1). However, the upper limit is not particularly limited as long as an engagement protrusion can be formed. However, the upper limit is preferably 5 or less, more preferably 4 or less, and still more preferably as shown in FIG. 3 or FIG. The number of protrusions is a two-stage or three-stage structure (three stages in FIG. 3 and two stages in FIG. 5), and has a so-called Christmas tree shape.

  For example, as shown in FIG. 4, an insect repellent or a fragrance is formed on the back surface (surface opposite to the stem) of the screen door fixture of the present invention (the surface opposite to the stem) or the surface fastener having the loop-like engagement element. An agent or a functional object (3) such as a box or a package having these is integrated. FIG. 4 shows an example of the screen door fixture of the present invention and a state in which a hook-and-loop fastener having a loop-shaped engagement element is attached, sandwiching the monofilament constituting the screen door screen of (4), It is sectional drawing in the surface (Y direction) orthogonal to the engagement element row | line | column direction (X direction) of the fixture for screen doors.

  The functional object (as described above) on the back surface (surface opposite to the stem) of the screen door fixture of the present invention (the surface opposite to the stem) or the back surface of the hook-and-loop fastener base fabric (5) having loop-like engagement elements ( As a method of attaching 3), any method such as bonding an adhesive, an adhesive, a hook-and-loop fastener, a stapler, sewing, a hook attached to the back surface of the substrate, or the like, may be inserted into a hole or the like attached to the back surface of the object.

  As functional objects (3) to be attached, in addition to the above-mentioned insect repellents, fragrances, deodorants, cases such as sheets, bottles, cans, boxes, etc. in which these are contained, decorations for interior decoration ( Decorations such as decorations for Christmas trees), decorative sheets such as decorative sheets represented by electrical decorations, etc. The daily necessities represented by etc. are mentioned.

  With respect to the size of the engaging element constituting the fixture of the present invention, the distance between the top of the engaging element and the substrate surface, that is, the stem height (H) shown in FIGS. The range is preferable, and if it is shorter than this range, it is difficult to obtain sufficient engagement even if it penetrates the network surface, and if it is longer than this range, it will also be difficult for the stem to fall down and penetrate the network surface. Sexual objects are easily detached. More preferably, it is the range of 1.2-3.0 mm.

  In addition, the distance between the engagement protrusion tips in the height direction of the stem (Z shown in FIGS. 3 and 5) is preferably in the range of 0.2 to 1.5 mm in terms of engagement force. More preferably, it is the range of 0.3-1.1 mm.

  As described above, it is preferable that the protrusion lengths of the engagement protrusions protruding from the stem to the side face have substantially the same dimensions, since the monofilaments constituting the net are not damaged when removed, and the protrusion lengths of the engagement protrusions (FIG. 3). Or S1) shown in FIG. 5 is preferably in the range of 0.05 to 0.3 mm. More preferably, it is the range of 0.07 mm-0.25 mm, More preferably, it is the range of 0.09-0.2 mm.

  When the protruding length of each engaging protrusion protruding from the stem (S shown in FIG. 3 or S1 shown in FIG. 5) is shorter than 0.05 mm, a high engaging force can be obtained with a hook-and-loop fastener having a loop-like engaging element. When the length is longer than this range, it is difficult to penetrate the mesh surface, and the functional object is easily detached.

  Further, in the fixture of the present invention, the stem width of the stem (D1 to D3 shown in FIGS. 3 and 5) is narrowed for each step where the engagement protrusion is present from the substrate surface to the top. Preferably, the stem width at the position where the second and subsequent engagement protrusions are present is less than the stem width immediately below the stem width at the position where the first-stage engagement protrusion near the substrate is present. When the number of engagement protrusions is three, the stem width (D1) where the first-stage engagement protrusion closest to the substrate is present is 0. The stem width (D2) of the portion where the second-stage engagement protrusion is present is 0.05 to 0.2 mm narrower than D1, and the third-stage engagement protrusion is present. It is preferable that the stem width (D3) of the portion to be narrowed is 0.05 to 0.2 mm narrower than D2.

  When the first-stage stem width (D1) is narrower than the above range, a sufficient engagement force cannot be obtained, and when it is larger than this range, it is difficult to penetrate the mesh surface, and the functional object comes off. It becomes easy. Further, when the widths of D2 and D3 are in the above range, the engaging element is difficult to fall or the ability to penetrate through various mesh screens is improved, and the engaging force is also improved.

  In addition, as shown in the figure, the engaging protrusions protrude in the target direction across the stem (stem), and the engaging elements are arranged in a row in a direction intersecting with the protruding direction of the engaging protrusion. Further, it is preferable that the engagement protrusions do not protrude in the direction of the engagement element row because it is easy to insert into the mesh of the screen door and does not damage the monofilament and the engagement element forming the mesh when removed. Further, since the engaging elements are arranged in a line, a high engaging force can be obtained with the hook-and-loop fastener having the loop-shaped engaging elements, and it is possible to attach even if the functional object is heavy.

  The thickness in the row direction of the stem (W shown in FIG. 2) is preferably 0.1 to 0.5 mm. When the thickness is smaller than this range, the strength of the engaging element is low, and when the thickness is larger than this range, This makes it difficult for the engaging element to penetrate the mesh.

  As described above, the fixture for a screen door according to the present invention has an engaging element in which the engaging element protrudes from the substrate surface, and the engaging protrusion protrudes from the stem to the side and is arranged in a plurality of stages in the stem height direction. Since there are a plurality of stages, the engaging force after penetrating the screen door is remarkably improved, and it is possible to cope with screen doors having different meshes. Preferably, there are two or more stages, and the upper limit is not particularly limited as long as the engagement protrusion can be formed, but it is preferably 5 stages or less, more preferably 4 stages or less, and still more preferably as shown in FIG. 3 or FIG. This is a case where the number of steps of the engaging protrusion is a two-step or three-step structure.

  The distance between the engagement elements in the direction of the engagement element row (S2 shown in FIG. 2) is preferably 0.1 to 2.0 mm. When the distance is smaller than this range, the engagement elements hardly penetrate the mesh, and the reverse If the distance is larger than this distance, the engaging element density is low, and a high engaging force with the surface fastener having the loop-shaped engaging element cannot be obtained.

  Furthermore, in the present invention, it is preferable that a plurality of stem rows exist on the substrate in parallel. Due to the presence of multiple rows in parallel, more loops of the hook-and-loop fastener having loop-like engagement elements are engaged, a high engagement force is obtained, the mounting state is stable, and the weight of the functional object is dispersed to form a network. Can be held on the surface.

Further, the engaging element density is preferably 10 to 40 per 1 cm ^{2 of the} substrate portion where the engaging element is present. When the engaging element density is less than this range, sufficient engaging force with the loop-shaped engaging element is obtained. It is necessary to use a mounting tool with a large area, and it is unnatural when the functional object is a small container or the like. It will be difficult to penetrate and will hurt the mesh. More preferably, the engaging element density is in the range of 15 to 35 / cm ² .

  In the screen door fixture of the present invention, there are 3 to 20 engagement elements per cm of the engagement element row, and such engagement element rows are 3 to 8 rows per cm of the fixture length. The presence is preferable in terms of the insertion property of the screen door into the mesh and the engaging force with the loop-shaped engaging element. More preferably, there are 5 to 15 engaging elements per cm of the engaging element row, and 4 to 7 rows of such engaging element rows per cm of the fixture.

Next, the manufacturing method of the screen door fixture of this invention is demonstrated.
1, 3, and 5, a known method for manufacturing a surface fastener with a male engagement element can be employed. However, a preferred example is as follows. A thermoplastic resin is melt-extruded from a nozzle having a slit as shown in the seen shape or in a state where a plurality of cross sections of the engaging elements shown in FIGS. A tape having a plurality of rows of engaging element rows that are continuous with each other is formed. Next, the line existing on the surface of the obtained tape is cut in a direction intersecting with the tape length direction from the tip of the line to the vicinity of the root at small intervals. A suitable interval between the cuts is 0.1 to 2.0 mm.

Next, the tape is stretched in the length direction. The stretching ratio is preferably such that the tape length after stretching is 2.0 to 5.0 times the length of the original tape. By this stretching, the cuts formed in the rows are expanded, and the rows become engagement element rows made up of a large number of independent engagement elements.
When the stretched tape thus obtained is cut at right angles to the length direction, the screen door fixture of the present invention is obtained.

  Next, a description will be given of a hook-and-loop fastener having a loop-like engagement element used as a set with the screen door fixture according to the present invention. As the hook-and-loop fastener having such a loop-like engagement element, a multifilament yarn is used on the base fabric. A hook-and-loop fastener that forms a loop is preferable. At the stage of weaving the base fabric, a loop-like lift made of the multifilament yarn is formed on the base fabric so that the multifilament yarn constituting the loop is woven into the base fabric and at the same time the loop is formed. The loop-shaped engagement element has a structure in which the surface of the loop hook-and-loop fastener has a structure in which a part of the filament of the multifilament yarn constituting the loop-shaped engagement element is pulled out of the loop or the multifilament bundle is disturbed. Preferably it is disturbed.

The general mesh having 18 to 30 mesh is preferable. And the thing whose diameter of the monofilament which comprises the mesh | network of the screen door is 0.12-0.35mm is suitable.

  The monofilament may be a synthetic fiber or a resin-coated surface of a metal fiber or glass fiber. In general, as the mesh constituting the screen door, a plain weave structure having the same warp weave density and weft weave density is used.

  When the functional object is attached to the screen surface of the screen door using the fixture of the present invention, it is preferable to attach the functional object to the indoor side in order to reduce the wetness of the functional object due to rain. Moreover, when importance is attached to the vision from the outside, it may be attached to the outdoor side. In that case, it is preferable that the total thickness of the attachment is within 20 mm so that the opening and closing of the glass door is not hindered by the attachment.

  As the size of the fixture of the present invention, a size of 1.0 cm × 1.0 cm to 5 cm × 5 cm in length × width is appropriate. Of course, a plurality of attachments for attachment depending on the size or weight of the attachment may be used.

  As described above, the screen door fixture of the present invention is used to attach a functional object to the screen surface of the screen door, specifically, a case or a sheet containing an insecticide or an insect repellent, It is used to attach functional objects represented by cases and sheets containing deodorizers and fragrances, decorative articles and electrical accessories to screen doors.

As a result of sensory evaluation of the ease of removal, the engagement element was pushed during attachment or removal, and the mesh was displaced, but it was easy to remove without being interrupted by the mesh. In addition, as an evaluation of durability, an attachment was attached to the screen surface of the screen door and left for one month. However, since there was only one stage of engagement element and the engagement force was low, it frequently dropped due to rain, wind and vibration.

  From the above results, when the number of engagement protrusions of the engagement element protruding from the surface of the substrate is one, it is very easy to attach to the screen door mesh, but the engagement force is weak and the functional object is likely to fall off. It can be seen that when the number of steps of the engaging protrusions is 2 to 3, the engaging force is high, the object is difficult to drop off, and the object is easy to attach.

  Moreover, the mesh door constituting monofilament was not damaged by the engagement and separation of these fixtures, and there was no hindrance to opening and closing the glass door existing inside the screen door.
