Summary of the Invention

Problems to be Solved by the Invention

[0004] In a sliding window having a screen window and a storm window, for example, as shown in FIG. 1 of Patent Document 1, on the upper frame of the sash frame, there are formed a rail for guiding the upper end of the screen window in the opening and closing direction of the screen window and a rail for guiding the upper end of the storm window in the opening and closing direction of the storm window, and between these two rails, a linear groove, a linear groove, is formed. As shown in FIG. 1 of Patent Document 1, a gap is formed between the upper ends of the screen window and the storm window and the upper surface of the linear groove. Therefore, in this sliding window, when the storm window is open, even if the screen window is closed, there is a possibility that insects may enter the room from between the upper ends of the screen window and the storm window and the upper surface of the linear groove.

[0005] Therefore, the object of the present invention is to provide an insect intrusion prevention device that can prevent insects from entering through the gap between the upper surface of a straight groove formed in the upper frame of the sash frame and the upper end of the screen door and the upper end of the outer sash in a sliding window having a screen door and an outer sash. [Means for solving the problem]

[0006] To solve the above problems, the insect intrusion prevention device of the present invention is formed on the upper frame of the sash frame of a sliding window having a screen door and an outer sash, and is an insect intrusion prevention device for preventing insects from entering between the upper surface of a straight groove formed between a rail for guiding the upper end of the screen door in the opening and closing direction of the screen door and a rail for guiding the upper end of the outer sash in the opening and closing direction of the outer sash, and the upper end of the screen door and the upper end of the outer sash, comprising a flat plate-shaped holding member arranged along the straight groove, an intrusion prevention member attached to the holding member, and a gripping member that is bendably connected to the holding member and fixed to the upper surface of the straight groove, wherein if one side in the thickness direction of the holding member is designated as the first direction side and the opposite side of the first direction side as the second direction side, the surface of the holding member on the first direction side faces the upper surface of the straight groove, the intrusion prevention member is attached to the surface of the holding member on the second direction side, and the gripping member is bendable at least in the second direction side relative to the holding member with the connection portion between the holding member and the gripping member as the boundary.

[0007] The insect intrusion prevention device of the present invention comprises a flat plate-shaped holding member positioned along a straight groove, with its first-direction side facing the upper surface of the straight groove, and an intrusion prevention member attached to the second-direction side of the holding member. Therefore, in the present invention, by installing the insect intrusion prevention device in the straight groove such that the intrusion prevention member is positioned in the central part of the upper frame of the sash frame in the opening and closing direction of the screen door, and above the portion in the straight groove where the vertical frame of the open outer sash overlaps with the vertical frame of the closed screen door, it becomes possible to prevent insects from entering between the upper surface of the straight groove formed in the upper frame of the sash frame and the upper end of the screen door and the upper end of the outer sash.

[0008] Furthermore, the insect intrusion prevention device of the present invention includes a gripping member that is bendably connected to a holding member, and the gripping member is bendable at least in a second direction relative to the holding member, with the connection portion between the holding member and the gripping member as the boundary. Therefore, in the present invention, when installing the insect intrusion prevention device in a straight groove, the gripping member is bent relative to the holding member so that a part of the gripping member is positioned below the straight groove, and while gripping the part of the gripping member positioned below the straight groove, the holding member and the intrusion prevention member are moved within the straight groove, making it possible to install the insect intrusion prevention device at a predetermined location within the straight groove. Thus, in the present invention, even when installing the insect intrusion prevention device in a straight groove of an existing sliding window, it is possible to easily install the insect intrusion prevention device.

[0009] Furthermore, in this invention, when removing the insect intrusion prevention device from a straight groove, the gripped member is bent relative to the holding member so that a portion of the gripped member is positioned below the straight groove. At the same time, while gripping the portion of the gripped member positioned below the straight groove, the holding member and the intrusion prevention member are moved within the straight groove, making it possible to remove the insect intrusion prevention device from the straight groove. Therefore, in this invention, it is possible to easily remove the insect intrusion prevention device placed in a straight groove.

[0010] In the present invention, the gripping member is preferably formed in a flat plate shape, and the surface of the gripping member on the first direction side faces the upper surface of the straight groove. With this configuration, it is possible to reduce the amount of protrusion of the gripping member from the upper surface of the straight groove when it is fixed to the upper surface of the straight groove. Therefore, even when the gripping member is fixed to the upper surface of the straight groove, it becomes possible to open and close the screen door and the outer sliding door smoothly.

[0011] In the present invention, the insect intrusion prevention device preferably includes an adhesive tape connecting a holding member and a gripped member, wherein the adhesive tape comprises a first tape portion attached to the second-direction side surface of the holding member and a second tape portion attached to the second-direction side surface of the gripped member. With this configuration, it becomes possible to smoothly bend the gripped member toward the second direction relative to the holding member while ensuring the connection strength between the holding member and the gripped member.

[0012] In the present invention, the insect intrusion prevention device is provided with double-sided tape for fixing the member to be gripped to the upper surface of the straight groove, and it is preferable that the double-sided tape is attached to the surface of the member to be gripped on the first direction side. With this configuration, it becomes possible to easily fix the member to be gripped to the upper surface of the straight groove by the double-sided tape. Furthermore, with this configuration, since the member to be gripped is fixed to the upper surface of the straight groove by the double-sided tape, it becomes possible to remove the insect intrusion prevention device installed in the straight groove more easily.

[0013] In the present invention, if the direction perpendicular to the direction of formation of the straight groove and the vertical direction is defined as the width direction of the straight groove, it is preferable that the gripped member is composed of two divided gripped members that are divided in the width direction of the straight groove. With this configuration, for example, even if a step is formed on the upper surface of the straight groove and it is difficult to fix the gripped member to the upper surface of the straight groove over the entire width direction of the straight groove, it becomes possible to fix only one of the divided gripped members to the upper surface of the straight groove, and as a result, it becomes possible to fix the gripped member to the upper surface of the straight groove.

[0014] In this invention, for example, the intrusion prevention member is a brush.

[0015] In the present invention, the outer shape of the intrusion prevention member, when viewed from the thickness direction of the retaining member, is preferably rectangular, oval, or elliptical, and the intrusion prevention member is rotatable relative to the retaining member with the thickness direction of the retaining member as the axis of rotation. With this configuration, by rotating the intrusion prevention member relative to the retaining member, it becomes possible to change the width of the intrusion prevention member in the width of the straight groove to which the insect intrusion prevention device is attached. Therefore, even when attaching insect intrusion prevention devices to straight grooves of different widths, it becomes possible to prevent insects from entering from between the upper end of the screen door and the upper end of the outer sash and the upper surface of the straight groove using a common insect intrusion prevention device.

[0016] In the present invention, it is preferable that the insect intrusion prevention device comprises a plurality of intrusion prevention members arranged in the direction in which the straight groove is formed. With this configuration, the plurality of intrusion prevention members can effectively prevent insects from entering between the upper end of the screen door and the upper end of the outer sash and the upper surface of the straight groove. [Effects of the Invention]

[0017] As described above, in the present invention, by attaching the insect intrusion prevention device of the present invention to a predetermined position in a sliding window having a screen door and an outer sash, it becomes possible to prevent insects from entering through the gap between the upper surface of the straight groove formed in the upper frame of the sash frame and the upper end of the screen door and the upper end of the outer sash.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0020] (Configuration of Insect Intrusion Preventer) FIG. 1 is a front view of an insect intrusion preventer 1 according to an embodiment of the present invention. FIG. 2 is a bottom view of the insect intrusion preventer 1 shown in FIG. 1. FIG. 3 is a front view of a sliding window 2 to which the insect intrusion preventer 1 shown in FIG. 1 is attached. FIG. 4 is a cross-sectional view of the E-E cross-section of FIG. 3. FIG. 5 is a cross-sectional view of a state where the insect intrusion preventer 1 is attached to the upper frame 8 shown in FIG. 4. FIG. 6 is a cross-sectional view of the F-F cross-section of FIG. 5.

[0021] The insect intrusion preventer 1 of this embodiment is used by being attached to the sliding window 2. As shown in FIGS. 3 and 4, the sliding window 2 includes an inner shutter 3 arranged on the indoor side, an outer shutter 4 arranged on the outdoor side, a screen door 5 arranged outside the outer shutter 4, and a sash frame 6 to which the inner shutter 3, the outer shutter 4, and the screen door 5 are attached so as to be openable and closable. In FIGS. 3 and 4, a state where the outer shutter 4 is open and the screen door 5 is closed is illustrated. The inner shutter 3 and the outer shutter 4 include a rectangular window glass, an upper frame (upper rail), a lower frame (lower rail), and vertical frames surrounding the periphery of the window glass. The screen door 5 includes a rectangular net, an upper frame, a lower frame, and vertical frames surrounding the periphery of the net. The sash frame 6 includes an upper frame 8, a lower frame 9, and vertical frames 10 surrounding the peripheries of the inner shutter 3, the outer shutter 4, and the screen door 5.

[0022] For convenience, in the following explanation, the Y1 direction side in Figure 3, etc., which is one side in the opening and closing direction of the inner sash 3, outer sash 4, and screen door 5, will be referred to as the "right" side, and the opposite side (the other side in the opening and closing direction of the inner sash 3, outer sash 4, and screen door 5), the Y2 direction side in Figure 3, etc., will be referred to as the "left" side. Furthermore, the X1 direction side in Figure 4, etc., which is one side in the direction perpendicular to the vertical and left-right directions, will be referred to as the "front" side, and the opposite side in Figure 4, etc., the X2 direction side, will be referred to as the "rear" side. In this configuration, the front side is the exterior side, and the rear side is the interior side.

[0023] The upper frame 8 of the sash frame 6 has a rail 8a for guiding the upper end of the screen door 5 in the left-right direction, a rail 8b for guiding the upper end of the outer sash 4 in the left-right direction, and a rail 8c for guiding the upper end of the inner sash 3 in the left-right direction. A straight groove 8d is formed between rail 8a and rail 8b. A straight groove 8e is formed between rail 8b and rail 8c. In other words, the upper frame 8 has straight grooves 8d and 8e.

[0024] The straight grooves 8d and 8e are rectangular grooves that are recessed upwards and extend horizontally. That is, the horizontal direction is the direction in which the straight grooves 8d and 8e are formed. The front-to-back direction is the width direction of the straight grooves 8d and 8e. The upper surface 8f of the straight groove 8d and the upper surface 8g of the straight groove 8e are planes perpendicular to the vertical direction. Note that steps may be formed on the upper surface 8f of the straight groove 8d and the upper surface 8g of the straight groove 8e.

[0025] A straight guide groove 5a is formed at the upper end of the screen door 5, into which the lower end of the rail 8a fits. A straight guide groove 4a is formed at the upper end of the outer sash 4, into which the lower end of the rail 8b fits. A straight guide groove 3a is formed at the upper end of the inner sash 3, into which the lower end of the rail 8c fits. The portion of the upper end of the screen door 5 behind the guide groove 5a and the portion of the upper end of the outer sash 4 in front of the guide groove 4a fit into the straight groove 8d. The portion of the upper end of the outer sash 4 behind the guide groove 4a and the portion of the upper end of the inner sash 3 in front of the guide groove 3a fit into the straight groove 8e.

[0026] As shown in Figure 4, a gap S1 is formed between the upper end of the screen door 5 and the upper end of the outer sash 4 and the upper surface 8f of the straight groove 8d. Also, a gap S2 is formed between the upper end of the outer sash 4 and the upper end of the inner sash 3 and the upper surface 8g of the straight groove 8e. The vertical width of gaps S1 and S2 is, for example, about 15 mm. The insect intrusion prevention device 1 is attached to the sliding window 2 to prevent insects from entering through the gap S1. The insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d and is positioned within the straight groove 8d.

[0027] The insect intrusion prevention device 1 comprises a flat plate-shaped holding member 13 positioned along a straight groove 8d, a brush 14 attached to the holding member 13 as an intrusion prevention member, a gripping member 15 that the user grasps when installing the insect intrusion prevention member 1 into the straight groove 8d and which is fixed to the upper surface 8f of the straight groove 8d, and double-sided tape 16 for fixing the gripping member 15 to the upper surface 8f of the straight groove 8d. In this embodiment, two brushes 14 are attached to the holding member 13. That is, the insect intrusion prevention device 1 comprises two brushes 14. The gripping member 15 is formed separately from the holding member 13. The gripping member 15 is flexibly connected to the holding member 13. The insect intrusion prevention device 1 comprises adhesive tape 17 connecting the holding member 13 and the gripping member 15.

[0028] The retaining member 13 is formed in a substantially rectangular, flat plate shape. The retaining member 13 is made of, for example, resin. When the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the retaining member 13 is positioned such that its thickness direction and vertical direction are substantially the same. If we consider the side in the W1 direction of Figure 1, which is one side in the thickness direction of the retaining member 13, as the first direction side, and the side in the W2 direction of Figure 1, which is the opposite side of the first direction side, as the second direction side, then when the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the surface 13a of the retaining member 13 on the first direction side faces upward, and the surface 13b of the retaining member 13 on the second direction side faces downward.

[0029] Furthermore, when the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the surface 13a of the retaining member 13 on the first direction side faces the upper surface 8f of the straight groove 8d. Also, when the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the direction of the long side of the retaining member 13, which is formed in a roughly rectangular flat plate shape, is roughly the same as the left-right direction, and the direction of the short side of the retaining member 13 is roughly the same as the front-back direction. The member to be gripped 15 is connected to one end of the retaining member 13 in the direction of its long side. The other end face of the retaining member 13 in the direction of its long side is chamfered in a curved shape.

[0030] The brush 14 is attached to the second-direction side surface 13b of the retaining member 13. When the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the two brushes 14 are arranged in the left-right direction. The brush 14 consists of a bristle bundle portion 18 made up of multiple bristle bundles and a base 19 to which the base portion of the bristle bundle is fixed. The bristle bundle is made up of, for example, many bristles made of resin with excellent elasticity. The base 19 is attached to the second-direction side surface 13b of the retaining member 13.

[0031] The bristle bundle portion 18 protrudes from the base 19 in the second direction. When the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the lower end of the bristle bundle portion 18 is in light contact with the upper end of the screen door 5 and the upper end of the outer sash 4, or a small gap is formed between the upper end of the screen door 5 and the upper end of the outer sash 4 and the lower end of the bristle bundle portion 18. The outer shape of the brush 14 when viewed from the thickness direction of the holding member 13 is rectangular. The length of the long side of the rectangular brush 14 is longer than the width of the short side of the holding member 13.

[0032] The brush 14 is rotatable relative to the retaining member 13, with the thickness direction of the retaining member 13 as the axis of rotation. The brush 14 is also rotatable relative to the retaining member 13 with its center as the pivot point. For example, the retaining member 13 and the base 19 have screw holes into which a screw 20 engages. By loosening the screw 20, the brush 14 becomes rotatable relative to the retaining member 13. When the screw 20 is tightened, the brush 14 is fixed to the retaining member 13. The screw 20 is, for example, a countersunk screw, with its head positioned on the first-direction side of the retaining member 13. By rotating the brush 14 relative to the retaining member 13, the fixing position of the brush 14 relative to the retaining member 13 can be changed, thereby altering the width of the brush 14 in the front-rear direction. The fixing position of the brush 14 relative to the retaining member 13 is adjusted according to the width of the straight groove 8d (width in the front-rear direction).

[0033] The gripped member 15 is formed in a flat plate shape. The gripped member 15 is made of the same material as the holding member 13, for example, resin. As described above, the gripped member 15 is connected to one end of the holding member 13 in the direction of its long side. When the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the thickness direction of the gripped member 15 coincides with the vertical direction. That is, when the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the surface 15a of the gripped member 15 on the first direction side faces upward, and the surface 15b of the gripped member 15 on the second direction side faces downward. Also, when the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the surface 15a of the gripped member 15 on the first direction side faces the upper surface 8f of the straight groove 8d.

[0034] As shown in Figure 2, the gripping member 15 in this embodiment is composed of two divided gripping members 21 that are divided in the front-rear direction. The divided gripping members 21 are formed in a substantially rectangular flat plate shape. When the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the direction of the long side of the substantially rectangular flat plate-shaped divided gripping member 21 is substantially the same as the left-right direction, and the direction of the short side of the divided gripping member 21 is substantially the same as the front-rear direction. The two divided gripping members 21 are adjacent in the front-rear direction. A small gap is formed between the two divided gripping members 21 in the front-rear direction.

[0035] The adhesive tape 17 comprises a first tape portion 17a that is attached to the second-direction side surface 13b of the holding member 13, and a second tape portion 17b that is attached to the second-direction side surface 15b of the gripped member 15. In this embodiment, the adhesive tape 17 is composed of the first tape portion 17a and the second tape portion 17b. Furthermore, the second tape portion 17b is composed of two divided tape portions 17c that are attached to the second-direction side surfaces of each of the two divided gripped members 21.

[0036] As described above, the gripped member 15 is bendably connected to the holding member 13. The gripped member 15 is bendable at least in a second direction relative to the holding member 13, with the connection between the holding member 13 and the gripped member 15 as the boundary. Specifically, the gripped member 15 is bendable at least 90° in the second direction relative to the holding member 13. In addition, the gripped member 15 is slightly bendable in the first direction relative to the holding member 13. Note that the gripped member 15 does not necessarily have to bend in the first direction relative to the holding member 13.

[0037] The double-sided tape 16 is attached to the first-direction side surface of each of the two divided gripping members 21. That is, the double-sided tape 16 is attached to the first-direction side surface 15a of the gripping member 15. Release paper is attached to the first-direction side surface of the double-sided tape 16. When fixing the gripping member 15 to the upper surface 8f of the straight groove 8d with the double-sided tape 16, the release paper on the first-direction side surface of the double-sided tape 16 is peeled off and the double-sided tape 16 is attached to the upper surface 8f.

[0038] (How to install insect intrusion prevention devices) Figure 7 is a cross-sectional view illustrating the method of attaching the insect intrusion prevention device 1 to the upper frame 8 shown in Figure 4. In Figure 7, a cross-section corresponding to the FF cross-section in Figure 5 is shown.

[0039] The insect intrusion prevention device 1 is installed in the straight groove 8d such that the brush 14 is positioned in the center of the upper frame 8 in the left-right direction, and above the part (part G in Figure 3) where the vertical frame of the open outer sash 4 and the vertical frame of the closed screen door 5 overlap in the front-to-back direction. The insect intrusion prevention device 1 is installed in the straight groove 8d such that, for example, the holding member 13 is positioned on the left side and the gripped member 15 is positioned on the right side. When installing the insect intrusion prevention device 1 in the straight groove 8d, for example, first move the outer sash 4 and screen door 5 so that they overlap on the left side of the sash frame 6 (see Figure 7).

[0040] Next, the retaining member 13 and brush 14 are inserted from the right side of the outer sash 4 and screen door 5 between the upper ends of the screen door 5 and outer sash 4 and the upper surface 8f of the straight groove 8d (see Figure 7). At this time, the person performing the installation bends the gripped member 15 with respect to the retaining member 13 so that the lower end of the gripped member 15 is below the straight groove 8d, and while gripping the lower end of the gripped member 15 which is positioned below the straight groove 8d, the retaining member 13 and brush 14 are moved to the left in the straight groove 8d so that the brush 14 is positioned in part G in Figure 3. After that, double-sided tape 16 is attached to the upper surface 8f of the straight groove 8d to fix the gripped member 15 to the upper surface 8f (see Figure 6).

[0041] Furthermore, when removing the insect intrusion prevention device 1 from the straight groove 8d, the worker moves the outer shoji screen 4 and the screen door 5 so that they overlap on the left side of the sash frame 6, for example, and then peels off the double-sided tape 16 from the upper surface 8f. After that, the worker bends the gripped member 15 with respect to the holding member 13 so that the lower end of the gripped member 15 is positioned below the straight groove 8d, and while gripping the lower end of the gripped member 15 positioned below the straight groove 8d, moves the holding member 13 and the brush 14 to the right in the straight groove 8d to remove the insect intrusion prevention device 1 from the straight groove 8d.

[0042] The insect intrusion prevention device 1 may also be installed in the straight groove 8d such that the holding member 13 is positioned on the right side and the gripped member 15 is positioned on the left side. In this case, when installing the insect intrusion prevention device 1 in the straight groove 8d, first, the outer sash 4 and the screen door 5 are moved so that they overlap on the right side of the sash frame 6. Then, from the left side of the outer sash 4 and the screen door 5, the holding member 13 and the brush 14 are inserted between the upper ends of the screen door 5 and the outer sash 4 and the upper surface 8f of the straight groove 8d to install the insect intrusion prevention device 1 in the straight groove 8d.

[0043] (Main effects of this form) As described above, in this embodiment, the insect intrusion prevention device 1 comprises a flat plate-shaped holding member 13 which is arranged along the straight groove 8d and whose first-direction side surface 13a faces the upper surface 8f of the straight groove 8d, and a brush 14 which is attached to the second-direction side surface 13b of the holding member 13. Therefore, in this embodiment, as described above, by installing the insect intrusion prevention device 1 in the straight groove 8d so that the brush 14 is arranged in part G of Figure 3, it becomes possible to prevent insects from entering between the upper end of the screen door 5 and the upper end of the outer sash 4 and the upper surface 8f of the straight groove 8d.

[0044] In particular, in this embodiment, since the two brushes 14 are arranged in the left-right direction which is the direction in which the straight groove 8d is formed, the two brushes 14 can effectively prevent insects from entering through the gap between the upper end of the screen door 5 and the upper end of the outer sash 4 and the upper surface 8f of the straight groove 8d.

[0045] In this embodiment, the outer shape of the brush 14 when viewed from the thickness direction of the retaining member 13 is rectangular. Furthermore, in this embodiment, the brush 14 is rotatable relative to the retaining member 13 with the thickness direction of the retaining member 13 as the axis of rotation, and the width of the brush 14 in the front-to-back direction can be changed by changing the fixing position of the brush 14 relative to the retaining member 13 according to the front-to-back width of the straight groove 8d to which the insect intrusion prevention device 1 is attached.Therefore, in this embodiment, even when the insect intrusion prevention device 1 is attached to a straight groove 8d with a different front-to-back width, it is possible to prevent insects from entering from between the upper end of the screen door 5 and the upper end of the outer sash 4 and the upper surface 8f of the straight groove 8d using a common insect intrusion prevention device 1.

[0046] In this embodiment, the insect intrusion prevention device 1 includes a gripping member 15 that is bendably connected to the holding member 13, and the gripping member 15 is bendable at least in a second direction relative to the holding member 13, with the connection portion between the holding member 13 and the gripping member 15 as the boundary. Therefore, in this embodiment, as described above, when installing the insect intrusion prevention device 1 in the straight groove 8d, it is possible to move the holding member 13 and the brush 14 in the straight groove 8d while gripping the lower end of the gripping member 15 which is positioned below the straight groove 8d, and to install the insect intrusion prevention device 1 at a predetermined location in the straight groove 8d. Thus, in this embodiment, even when installing the insect intrusion prevention device 1 in the straight groove 8d of an existing sliding window 2, it is possible to easily install the insect intrusion prevention device 1.

[0047] Furthermore, in this embodiment, when removing the insect intrusion prevention device 1 from the straight groove 8d, as described above, the lower end of the gripped member 15, which is positioned below the straight groove 8d, is gripped while the holding member 13 and brush 14 are moved within the straight groove 8d, making it possible to remove the insect intrusion prevention device 1 from the straight groove 8d. Therefore, in this embodiment, the insect intrusion prevention device 1 positioned within the straight groove 8d can be easily removed.

[0048] In particular, in this embodiment, since the gripping member 15 is fixed to the upper surface 8f of the straight groove 8d by double-sided tape 16, it becomes easier to remove the insect intrusion prevention device 1 when it is installed in the straight groove 8d. Also, in this embodiment, since the gripping member 15 is fixed to the upper surface 8f of the straight groove 8d by double-sided tape 16, it becomes easier to fix the gripping member 15 to the upper surface 8f.

[0049] In this embodiment, the gripping member 15 is formed in a flat plate shape, and the surface 15a of the gripping member 15 on the first direction side faces the upper surface 8f of the straight groove 8d. Therefore, in this embodiment, it is possible to reduce the amount of protrusion of the gripping member 15 from the upper surface 8f when it is fixed to the upper surface 8f by double-sided tape 16. Consequently, in this embodiment, even when the gripping member 15 is fixed to the upper surface 8f, it is possible to open and close the screen door 5 and the outer sliding door 4 smoothly.

[0050] In this embodiment, the holding member 13 and the member to be gripped 15 are connected by an adhesive tape 17, which consists of a first tape portion 17a attached to the second-direction side surface 13b of the holding member 13 and a second tape portion 17b attached to the second-direction side surface 15b of the member to be gripped 15. Therefore, in this embodiment, it is possible to smoothly bend the member to be gripped 15 toward the second direction relative to the holding member 13 while ensuring the connection strength between the holding member 13 and the member to be gripped 15.

[0051] In this embodiment, the gripped member 15 is composed of two divided gripped members 21 that are divided in the front-rear direction. Therefore, in this embodiment, for example, even if a step is formed on the upper surface 8f of the straight groove 8d, making it difficult to fix the gripped member 15 to the upper surface 8f of the straight groove 8d over the entire width of the straight groove 8d, it becomes possible to fix only one of the divided gripped members 21 to the upper surface 8f, and as a result, it becomes possible to fix the gripped member 15 to the upper surface 8f.

[0052] (Other embodiments) In the above-described embodiment, the gripped member 15 may be formed integrally with the holding member 13. In this case, for example, a half-cut is made from the first direction side at the boundary between the holding member 13 and the gripped member 15, so that the thickness of the boundary between the holding member 13 and the gripped member 15 is reduced. Even in this case, the gripped member 15 is still bendable at least in the second direction relative to the holding member 13.

[0053] In the above-described embodiment, the number of brushes 14 attached to the holding member 13 may be three or more, or it may be just one. Also, in the above-described embodiment, the brush 14 may be rotatable relative to the holding member 13 with a pivot point offset from the center of the brush 14. Furthermore, in the above-described embodiment, the outer shape of the brush 14 when viewed from the thickness direction of the holding member 13 may be an oval or an ellipse. Also, in the above-described embodiment, the brush 14 does not have to be rotatable relative to the holding member 13. In this case, for example, the outer shape of the brush 14 when viewed from the thickness direction of the holding member 13 may be circular or square.

[0054] In the above-described embodiment, the gripped member 15 may be composed of three or more divided gripped members 21 that are divided in the front-to-back direction, or it may not be divided in the front-to-back direction. Also, in the above-described embodiment, the insect intrusion prevention device 1 may not be provided with double-sided tape 16. In this case, for example, the gripped member 15 is fixed to the upper surface 8f of the straight groove 8d by a screw. Furthermore, in the above-described embodiment, the gripped member 15 may not be formed in a flat plate shape.

[0055] In the above-described embodiment, the insect intrusion prevention device 1 may be equipped with, for example, a spatula plate as an intrusion prevention member instead of the brush 14. In this case, the spatula plate is formed in the shape of a rectangular flat plate from, for example, rubber or resin, and when the insect intrusion prevention device 1 is attached to the upper surface 8f of the straight groove 8d, the thickness direction and the left-right direction of the spatula plate are substantially coincide. Alternatively, in the above-described embodiment, the insect intrusion prevention device 1 may be equipped with, for example, an intrusion prevention member formed in the shape of a rectangular parallelepiped instead of the brush 14. In this case, the intrusion prevention member is formed from, for example, rubber or resin. [Explanation of Symbols]
