Description

  The present invention provides a window frame capable of electromagnetic shielding and an electromagnetic shielding film affixed to a plate glass when an electromagnetic shielding film having a specification in which a conductive layer is exposed on a surface facing the plate glass side is used for an electromagnetic shielding window. The present invention relates to an electromagnetic shielding film mounting tool for an electromagnetic shielding window that is suitable for obtaining electrical continuity, an electromagnetic shielding window using the same, and a method for constructing an electromagnetic shielding window.

In recent years, an electromagnetic shielding film with a conductive layer has been applied to the window glass to prevent leakage of external radio waves from the space inside the building and to prevent external radio waves from entering the space inside the building as noise. In addition, various electromagnetic shielding windows that electromagnetically shield the space in the building have been proposed (see, for example, Patent Document 1).
In the technique described in Patent Document 1, an electromagnetic shielding window is constructed by attaching an electromagnetic shielding film consisting only of a conductive layer to a plate glass. However, as in the technique described in Patent Document 1, an electromagnetic shielding film consisting only of a conductive layer has no problem in conducting electricity, but the conductive layer is exposed on the plate glass surface of the window. There is room for improvement in preventing performance deterioration of the conductive layer, such as scratches.

  On the other hand, like the electromagnetic shielding film 110 shown in FIG. 4, an electromagnetic wave having a conductive layer 11 and an insulating protective layer (PET layer or the like) 12 attached so as to cover the front and back surfaces of the conductive layer 11. Shielding films have also been proposed. When an electromagnetic shielding window is constructed with the electromagnetic shielding film 110, the adhesive 13 is applied to one surface of the protective layer 12 and attached to the surface of the plate glass. Thereby, electromagnetic shielding can be performed by the conductive layer 11 and deterioration of the conductive layer 11 can be prevented by the protective layer 12.

  However, since the front and back surfaces of the conductive layer 11 are covered with the protective layer 12 in the electromagnetic shielding film 110 shown in FIG. 4, the electromagnetic shielding film 110 is pasted like the electromagnetic shielding window 111 shown in FIG. When the plate glass 2 is attached to the window frame 3 via the conductive gasket 5, the protective layer 12 interferes with the conduction between the conductive layer 11 and the window frame 3 and causes conduction failure. Therefore, the shield layer S (the bold line portion shown in the figure (hereinafter the same)) shown in the figure is discontinuous as it is, and there is a problem in ensuring reliable conduction between the conductive layer 11 and the window frame 3.

  Therefore, a film provided with a protective layer 12 only on one surface of the conductive layer 11 like the electromagnetic shielding film 10 shown in FIG. 6 is used directly on the conductive layer 11 like the electromagnetic shielding window 101 shown in FIG. It is effective to apply the adhesive 13 and apply it to the surface of the plate glass 2. When performing such construction, it is preferable to use a conductive mounting tool 120 such as a sealing tape as shown in FIG.

  And it attaches to the edge part of the plate glass 2 so that the surface of the mounting tool 120 may follow the surface of the plate glass 2, and the electromagnetic shielding film 10 is affixed on the surface of the plate glass 2 so that it may overlap with the surface of this mounting tool 120. If it is such construction, since the protective layer 12 is provided in the surface on the opposite side to the plate glass side of the electromagnetic shielding film 10, the performance degradation of the electromagnetic shielding film 10 can be prevented or suppressed. Moreover, the conductive layer 11 of the electromagnetic shielding film 10 and the window frame 3 can be conducted through the conductive mounting tool 120.

Japanese Patent Laying-Open No. 2001-274584 (FIG. 1)

  However, even in the construction shown in FIG. 7, when the electromagnetic shielding film 10 is attached to the surface of the plate glass 2, an adhesive is applied to the surface of the conductive layer 11. Therefore, in practice, as shown in FIG. 4B, the adhesive layer (adhesive layer) 13 becomes a dielectric and enters between the conductive layer 11 and the mounting tool 120 (reference t in the same figure). (See the portion), the mutual conduction is hindered and the conduction is insufficient, and there is a problem in continuously forming the shield layer S. In other words, even in the construction as shown in FIG. 7, there is still room for improvement in reliably connecting the conductive layer 11 and the window frame 3 through the mounting tool 120.

  Therefore, the present invention has been made paying attention to such problems, and when an electromagnetic shielding film in which its conductive layer is directly attached to the surface of a plate glass with an adhesive is used for an electromagnetic shielding window, An object of the present invention is to provide an electromagnetic shielding film mounting tool for an electromagnetic shielding window capable of reliably conducting a layer and a window frame, an electromagnetic shielding window using the same, and a method for constructing the electromagnetic shielding window.

  Moreover, in order to solve the said subject, the electromagnetic shielding window which concerns on 1 aspect of this invention is the plate glass, the electromagnetic shielding film by which an electroconductive layer is directly affixed on the surface of this plate glass with an adhesive agent, and the said plate glass. A window frame capable of electromagnetic shielding supported via a setting block, a conductive gasket interposed between the window frame and the front and back surfaces of the plate glass, the conductive gasket, and affixed to the plate glass An electromagnetic shielding window comprising: the electromagnetic shielding film; and an attachment device attached to an edge of the plate glass so as to establish mutual conduction with the window frame, and the attachment device is an aspect of the present invention. The electromagnetic shielding film mounting tool for an electromagnetic shielding window is mounted.

  Moreover, in order to solve the said subject, the construction method of the electromagnetic shielding window which concerns on 1 aspect of this invention constructs an electromagnetic shielding window with the electromagnetic shielding film by which an electroconductive layer is directly affixed on the surface of a plate glass with an adhesive agent. The electromagnetic shielding film mounting device according to one aspect of the present invention is used, the edge portion of the plate glass is pointed outward with the pointed convex portion of the mounting device, and the body portion is A mounting device mounting step for mounting at a position having a surface overlapping with the facing surface of the electromagnetic shielding film, a film pasting step for bonding the electromagnetic shielding film to the plate glass after the mounting device is mounted, and upper and lower sides of the plate glass The end face is supported by a window frame that can be electromagnetically shielded by a setting block, and a conductive gasket is attached to the front and back surfaces of the plate glass, and the conductive gasket, the fitting, and the electromagnetic shielding are attached. Characterized in that it comprises a glass sheet mounting step of taking a mutual continuity of the film and the window frame.

When the upper and lower end surfaces are supported by the setting block To, by interposing a conductive gasket to the front and back surfaces of the glass sheet, it may be applied to electromagnetic shielding windows.

  That is, if an electromagnetic shielding window is constructed using this wearing tool, the pointed convex portion of the wearing tool protrudes on the opposite surface of the electromagnetic shielding film toward the side opposite to the plate glass side. The pointed convex portion penetrates the thin and soft adhesive layer of the electromagnetic shielding film, and thereby the tip of the convex portion can be brought into direct contact with the conductive layer.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings as appropriate. In addition, about the structure similar to the example shown to FIGS. 4-7 mentioned above, the same code | symbol is attached | subjected and demonstrated.
In FIG. 1, one Embodiment of the electromagnetic shielding window which concerns on this invention constructed | assembled using the mounting tool which concerns on this invention is shown. As shown in the figure, the electromagnetic shielding window 1 has a window frame 3 capable of electromagnetic shielding, and a plate glass 2 is supported on the window frame 3 via upper and lower setting blocks 4. As the window frame 3 capable of electromagnetic shielding, for example, an aluminum sash can be used. The electromagnetic shielding film 10 shown in FIG. 6 is affixed to the plate glass 2 on the surface facing the room side of the plate glass 2 (the surface on the right side of the drawing). In this example, in the electromagnetic shielding film 10, the conductive layer 11 is directly attached with the adhesive 13 over the entire surface on the indoor side of the plate glass 2, and the protective layer 12 is provided on the indoor surface. Further, a conductive gasket 5 is interposed between the window frame 3 and the front and back surfaces of the plate glass 2.

Here, a mounting tool 20 is mounted on the upper and lower edges of the glass sheet 2 so that the electromagnetic shielding film 10 and the window frame 3 are mutually connected to the electromagnetic shielding window 1.
Specifically, as shown in FIG. 2, the wearing tool 20 includes a thin plate-like main body portion 21 and a pointed convex portion 22. The main body 21 is made of a flexible material having electrical conductivity such as a sealing tape, and is formed in a rectangular shape in a plan view in the unfolded state (see FIG. 5B). The convex portion 22 is made of a conductive material such as metal, and a plurality of convex portions 22 are formed on one surface of the main body portion 21. In the example of the figure, each convex portion 22 is formed from a conical protrusion having a base end portion on the main body portion 21 side (see FIG. 10C), and a plurality of convex portions 22 are formed on one side of the main body portion 21. Are arbitrarily arranged over the entire surface (see FIG. 4B).

  Since the main body portion 21 is made of a thin plate-like flexible member, the wearing tool 20 is in an unfolded state as shown in FIG. 2B when the wearing tool 20 is not used. On the other hand, when the mounting tool 20 is used, the flat surface side on which the convex portion 22 is not formed is set inward at the positions of the two folded portions β shown in FIG. As shown in FIG. 2 (a), it is folded back into a substantially U shape, and is attached to the edge of the glass sheet 2 in the folded back substantially U shape (see FIG. 1 (b)). An adhesive can be used to attach the edge of the plate glass 2.

  Here, since the main body portion 21 is folded at the two folded portions β, three surfaces 21a, 21b, and 21c are formed at the time of mounting, but the mounting tool 20 is the edge of the plate glass 2. The three surfaces 21 a, 21 b, 21 c of the main body 21 have a central surface 21 c facing the end surface 2 c of the plate glass 2, and the left and right side surfaces 21 a, 21 b are on the front and back of the plate glass 2. It is mounted so as to face the surfaces 2a and 2b.

  In this example, the first side surface 21a of the main body portion 21 is the facing surface of the electromagnetic shielding film 10 attached to the plate glass 2 (that is, the surface to which the adhesive 13 is applied (hereinafter also referred to as “adhesive layer 13”)). It is supposed to overlap with the surface. Then, by the folding back of the main body portion 21, the pointed convex portion 22 is projected toward the adhesive layer 13 of the electromagnetic shielding film 10. In addition, it is desirable that the height of the convex portion 22 be formed sufficiently higher than the thickness of the adhesive layer 13. In the example of this embodiment, the height of the convex portion 22 is set to a dimension higher than the thickness of the adhesive layer 13.

Next, the construction method of this electromagnetic shielding window 1 is demonstrated.
When constructing the electromagnetic shielding window 1, first, the mounting tool 20 is mounted on the edge of the plate glass 2. The mounting tool 20 is turned back at the two folded portions β with the convex portion 22 of the mounting tool 20 facing outward, and the positions of the two folded portions β are adjusted to adjust the first side surface 21a of the main body portion 21. Is mounted so as to be a surface overlapping the adhesive layer 13 which is the facing surface of the electromagnetic shielding film 10 (mounting device mounting step). In the example of this embodiment, the mounting tool 20 is mounted on each of the upper, lower, left and right sides of the plate glass 2 as the edge of the plate glass 2. In addition, in order to stabilize the attachment position of the mounting tool 20 and improve workability, it is preferable to apply a small amount of adhesive on the flat surface side that is the inner side of the mounting tool 20.

  Subsequently, after attaching the mounting tool 20 to the edge of the plate glass 2, the electromagnetic shielding film 10 is bonded to the plate glass 2 with an adhesive (film bonding step). At this time, it is preferable to firmly press the adhesive layer 13 of the electromagnetic shielding film 10 in a portion overlapping the first side surface 21 a of the main body 21. Thereby, the pointed convex part 22 penetrates the thin and soft adhesive layer 13 of the electromagnetic shielding film 10, and the convex part tip can be brought into direct contact with the conductive layer 11. In particular, in the example of the present embodiment, the height of the convex portion 22 is set to a dimension higher than the thickness of the adhesive layer 13, which is suitable for bringing the tip of the convex portion into direct contact with the conductive layer 11.

  Next, the upper and lower end surfaces of the plate glass 2 are supported on the window frame 3 by the setting block 4 and conductive gaskets (backup members) 5 are mounted on the front and back surfaces of the plate glass 2 (plate glass mounting step). Here, each conductive gasket 5 is disposed at a position facing the two left and right side surfaces 21 a and 21 b of the mounting tool 20. Thereby, the plate glass 2 is installed at a predetermined position with respect to the window frame 3. Moreover, the convex part 22 of the 2nd side surface 21b contact | abuts the conductive gasket 5 arrange | positioned in the opposing position among the two side surfaces 21a and 21b of the right and left of the main-body part 21. FIG.

  Therefore, a pressing action due to the elastic force of the conductive gasket 5 is also applied, so that the pointed convex portion 22 comes into contact with the conductive layer 11 more reliably. Thereby, as shown in FIG.1 (b), the window frame 3-the conductive gasket 5 (the left side of the figure)-the mounting tool 20-the conductive layer 11 will be in an electrical communication state. Since the structure of the upper and lower end surfaces of the plate glass 2 is the same, the electromagnetic shielding film 10 having the conductive layer 11 is attached to the window frame 3 in a conductive state over the entire surface of the plate glass 2 as shown in FIG. Therefore, the shield layer S is continuously formed by the electromagnetic shielding window 1, and the space in the building is reliably shielded electromagnetically.

Next, the operation and effect of the mounting tool 20, the electromagnetic shielding window 1 using the same, and the construction method of the electromagnetic shielding window 1 will be described.
As described above, the mounting tool 20 of the present embodiment is formed of a conductive material, and is formed on a flexible thin plate-like main body 21 and one surface of the main body 21. When the mounting tool 20 is mounted on the edge of the plate glass 2, the thin plate-shaped main body portion 21 becomes the facing surface of the electromagnetic shielding film 10 attached to the plate glass 2. While having the surface which overlaps with the contact bonding layer 13, the peak-shaped convex part 22 protrudes toward the contact bonding layer 13, Therefore Construction of the electromagnetic shielding window 1 is carried out using this mounting tool 20 When performing, on the edge of the plate glass 2 with the pointed convex portion 22 facing outward, the main body portion 21 is mounted at a position having the first side surface 21a overlapping the adhesive layer 13 of the electromagnetic shielding film 10, and thereafter Attaching the electromagnetic shielding film 10 to the plate glass 2 with an adhesive By supporting the upper and lower end surfaces of the plate glass 2 with the setting block 4 and interposing the conductive gasket 5 on the front and back surfaces of the plate glass 2 at positions facing the convex portions 22 of the second side surface 21b of the mounting tool 20. The electromagnetic shielding window 1 in which the shield layer S is continuously formed can be applied.

  That is, when the electromagnetic shielding window 1 is constructed using the mounting tool 20, the pointed convex portion 22 of the mounting tool 20 faces the side opposite to the plate glass 2 side and the adhesive layer of the electromagnetic shielding film 10. 13, the pointed convex portion 22 penetrates the thin and soft adhesive layer 13 of the electromagnetic shielding film 10, and thus the tip of the convex portion can be brought into direct contact with the conductive layer 11. Therefore, electrical conduction between the conductive layer 11 and the window frame 3 can be ensured. Moreover, since the electromagnetic shielding film 10 shown in FIG. 6 is used, since the protective layer (PET layer or the like) 12 is provided on the surface of the film (inner side), the electromagnetic shielding film 10 is damaged due to damage after construction. Performance degradation can be prevented or suppressed.

The electromagnetic shielding film mounting tool for an electromagnetic shielding window according to the present invention, the electromagnetic shielding window using the same, and the method of constructing the electromagnetic shielding window are not limited to the above-described embodiments, and depart from the spirit of the present invention. Otherwise, various modifications are possible.
For example, in the electromagnetic shielding film 10, the conductive layer 11 is directly attached to the surface of the plate glass 2 with an adhesive. In the above embodiment, the adhesive layer 13 is formed by applying an adhesive to the conductive layer 11. Although described with the example formed, it is not limited to this, The contact bonding layer 13 which covers the conductive layer 11 can also be formed previously.

Further, for example, in the above-described embodiment, as an example of the pointed convex portion 22 formed on one surface of the main body portion 21, the example in which the convex portion 22 is formed from a plurality of conical protrusions has been described. However, the present invention is not limited to this.
For example, as shown in FIG. 3, the peak-shaped convex portion 22 may be formed by a mountain-shaped protrusion with a continuous peak shape (see FIGS. 3A and 3B). . In the example shown in FIGS. 4A and 4B, a plurality of protrusions are provided in a lattice shape on one surface of the main body portion 21 as the pointed convex portion 22. Further, the protrusion of this modification has a triangular prism shape with the longitudinal direction as an axis, and one surface along the axial direction of the triangular prism shape is fixed to the main body portion 21 so as to face the one surface. The side on the side is a pointed convex portion. Also in this modification, the height of the convex portion 22 is set to a dimension higher than the thickness of the adhesive layer 13.

  Moreover, also when arrange | positioning arbitrarily the some convex part 22 over the whole surface of one surface of the main-body part 21, the convex part 22 is not limited to a several cone-shaped protrusion, For example, FIG. As in the modification shown in (d), the plurality of convex portions 22 are formed by semispherical protrusions (see FIG. 10C), or the plurality of convex portions 22 are formed by square columnar protrusions ( Further, the plurality of convex portions 22 can be formed by triangular pyramidal columnar protrusions (see FIG. 5E).

  Even if the convex portion 22 is configured as in these modifications, the thin plate-shaped main body portion 21 is attached to the plate glass 2 when the mounting tool 20 is mounted on the edge portion of the plate glass 2. The convex part 22 which is folded back so as to have a surface (first side surface 21 a) overlapping the adhesive layer 13 of the film 10 and the protrusions are provided in a lattice shape can be provided protruding toward the adhesive layer 13. Therefore, similarly to the mounting tool 20 of the above-described embodiment, the adhesive layer 13 of the electromagnetic shielding film 10 can be penetrated by the pointed convex portion 22 and the tip of the convex portion can be brought into direct contact with the conductive layer 11. .
