JP7748826B2 - Screen doors and building materials with screen doors - Google Patents

Description

This disclosure relates to screen doors and building fixtures with screen doors.

Frameless screen doors with resin attachments on all four edges are known. For example, the screen door described in Patent Document 1 is attached by fitting the attachment into a fitting groove provided in the frame of the fixture.

Patent Document 1 discloses that when removing a screen door for cleaning, replacing, etc., the attachment is rotated within the fitting groove by pushing in the pushing portion of the attachment. Once the attachment has rotated within the fitting groove, the protrusion on the indoor side elastically overcomes the engaging protrusion on the indoor side within the fitting groove, thereby disengaging the attachment and allowing it to be removed from the fitting groove.

Japanese Patent Application Laid-Open No. 2019-148107

Depending on the shape of the frame, it may be impossible to remove the attachment. Specifically, with conventional technology, when the push-in part is pushed in, the bottom plate part of the attachment comes into contact with the bottom surface of the fitting groove, and the arcuate surface is guided by the inclined surface on the outdoor side of the fitting groove, causing the attachment to rotate. However, if the attachment is attached to another product whose bottom surface of the fitting groove is positioned deeper than the bottom plate part, the attachment will sink deep into the fitting groove when the push-in part is pushed in, making it impossible to remove it from the fitting groove.

This disclosure has been made in consideration of the above points, and aims to provide a screen door and a fitting with a screen door that improves the ease of removing attachments regardless of the shape of the frame.

The present disclosure provides a rectangular mesh section having edges extending in a first direction and a second direction perpendicular to each other, a first edge member arranged along the edge extending in the first direction of the mesh section, and attached to a frame body of a fixture when fitted into a fitting groove provided on the frame body, and provided with a first position restricting portion that restricts the position of the mesh section main body in the projection direction when pulled out , and a second edge member arranged along the edge extending in the second direction of the mesh section, and attached to the frame body when fitted into a fitting groove provided on the frame body , and provided with a second position restricting portion that restricts the position of the mesh section main body in the projection direction when pulled out from the fitting groove, wherein the first edge member and the second edge member are positioned on the inside of the fitting groove. a pair of engaging protrusions protruding from the surface to the indoor side and the outdoor side, respectively, each having an inner engaging portion that engages with the inside of the engaging groove, and at least one of the first edge member and the second edge member has a push-in portion that protrudes outside the engaging groove further than the engaging protrusion on the indoor side when fitted into the engaging groove, and a first outer engaging portion that engages with the engaging protrusion on the outdoor side from the outside of the engaging groove when fitted into the engaging groove, and at least one of the first edge member and the second edge member is held within the engaging groove, away from the bottom surface of the engaging groove, and is rotatable around the point of contact between the engaging protrusion on the outdoor side and the inner engaging portion on the outdoor side.

Embodiments of the screen door and fittings with screen door of the present disclosure will be described below with reference to Figures 1-8. The following embodiment shows one aspect of the present disclosure, does not limit the disclosure, and can be modified as desired within the scope of the technical concept of the present disclosure. In the following drawings, the scale and number of components may differ from the actual structure to make each component easier to understand.

The overall structure of the screen door fitting 1 will now be described. As shown in Figure 1, the screen door fitting 1 comprises a frame 2 that is attached to an opening (not shown) formed in the wall of a building, and a screen 4 that is stretched over the frame 2. In the following description, the screen door fitting 1 will be simply referred to as fitting 1. In other words, fitting 1 corresponds to the screen door fitting 1.

Hereinafter, the direction that is up and down when viewing the fitting 1 attached to an opening in a building from the indoor side will be referred to as the up-down direction, and the direction that is left and right will be referred to as the left-right direction. The up-down direction corresponds to the first direction. The left-right direction corresponds to the second direction. In the fitting 1, the direction that is perpendicular to the left-right direction and runs along the indoor-outdoor direction will be referred to as the view direction.

The fitting 1 is, for example, a composite fitting having a frame 2 made of a metal such as aluminum and a resin such as polyvinyl chloride, and has excellent thermal insulation properties. The frame 2 has a pair of upper and lower frames 21 and 22 arranged opposite each other in the vertical direction and extending in the left-right direction, and a pair of vertical frames 23 and 24 arranged opposite each other in the left-right direction and extending in the vertical direction, as shown in Figure 2. The upper and lower frames 21 and 22 correspond to the second frame. The vertical frames 23 and 24 correspond to the first frame. The vertical frame 23 is arranged on the left side. The vertical frame 24 is arranged on the right side. The upper and lower frames 21 and 22 are connected to the vertical frames 23 and 24, respectively, at both left-right ends. In other words, the frame 2 is assembled in a so-called vertical through-hole configuration, where the vertical frames 23 and 24 are connected to the upper and lower frames 21 and 22, respectively. The materials for the pair of upper and lower frames 21 and 22, and the pair of vertical frames 23 and 24 are not particularly limited, and extruded materials such as aluminum and resin can be used.

The screen door 4 is a frameless screen door in which the ends of the mesh portion 41 are directly attached to the frame body 2. The screen door 4 is detachably stretched across the upper frame 21, lower frame 22, and vertical frames 23, 24 of the frame body 2. Specifically, the upper frame 21 and lower frame 22 have mating grooves 26 formed as recessed grooves on their respective visible surfaces 21a, 22a. The mating grooves 26 extend in the left-right direction and penetrate the upper frame 21 and lower frame 22, respectively. The vertical frames 23, 24 have mating grooves 25 formed as recesses on their respective visible surfaces 23a, 24a, respectively. The mating grooves 25 extend in the up-down direction and penetrate the vertical frames 23, 24, respectively. The mating grooves 25 and mating grooves 26 are located at the same position in the visible direction and are connected to each other around the four sides of the frame body 2.

The screen door 4 is tensioned by removably fitting its upper and lower edges into the fitting grooves 26 of the upper and lower frames 21 and 22. The screen door 4 is tensioned by removably fitting its left and right edges into the fitting grooves 25 of the vertical frames 23 and 24.

The configuration of the screen door 4 will be explained in more detail using Figure 3. The top and bottom of the screen door 4 shown in Figure 3 correspond to the top and bottom of the fitting 1 shown in Figure 1.

The screen door 4 has a rectangular mesh section 41, a pair of vertical edge members 42, 42, a pair of horizontal edge members 43, 43, and position control members 42A, 43A. The pair of vertical edge members 42, 42 extend in the vertical direction. The pair of vertical edge members 42, 42 are arranged on the left and right edges of the mesh section 41. The vertical edge members 42, 42 correspond to the first edge members. In other words, the pair of vertical edge members 42, 42 are arranged along the left and right edges of the mesh section 41 that extend in the vertical direction.

A pair of horizontal edge members 43, 43 extend in the left-right direction. The pair of horizontal edge members 43, 43 are arranged on the upper and lower edges of the mesh portion 41. The horizontal edge members 43, 43 correspond to second edge members. In other words, the pair of horizontal edge members 43, 43 are arranged along the upper and lower edges extending in the left-right direction of the mesh portion 41. The vertical edge member 42 is an attachment that fits into the fitting groove 25 of the vertical frame 23 or vertical frame 24 of the frame body 2. The horizontal edge member 43 is an attachment that fits into the fitting groove 26 of the upper frame 21 or lower frame 22 of the frame body 2.

The mesh portion 41 has a rectangular mesh main body 411 and a tape portion 412. The tape portion 412 has a locking member 412a and a flexible member 412b. The flexible member 412b is, for example, a flexible cloth material. The flexible member 412b extends from the mesh main body 411 on both sides in the vertical direction and the horizontal direction. The flexible member 412b extends from the four peripheral edges of the mesh main body 411. For example, the flexible member 412b is sewn to the mesh main body 411. The flexible member 412b may also be glued to the mesh main body 411.

Multiple locking members 412a are provided along the outer edge of the flexible member 412b. The locking members 412a are formed thicker than the flexible member 412b. The locking members 412a of the vertical tape portions 412 located on the left and right sides of the mesh portion 41 are formed over the entire vertical length of the mesh portion 41. The locking members 412a of the horizontal tape portions 412 located above and below the mesh portion 41 do not extend over the entire horizontal length of the mesh portion 41, and a predetermined gap is provided between the locking members 412a of the vertical tape portions 412 to allow the vertical tape portions 412 to be inserted into the vertical edge member 42, as described below. As an example, the tape portion 412 is composed of a zipper tape half having teeth as the locking members 412a.

The vertical edge members 42 are attached by engaging with the tape portions 412 on the vertical sides of the mesh portion 41 when the screen door 4 is not attached to the frame 2 of the fitting 1. The horizontal edge members 43 are separate and do not engage with the mesh portion 41 when the screen door 4 is not attached to the frame 2 of the fitting 1. Because the horizontal edge members 43 are separate from the mesh portion 41, the mesh portion 41 can be easily rolled up around one of the vertical edge members 42 before being attached to the frame 2 and after being removed from the frame 2, thereby reducing packaging. This allows for space savings when storing and transporting the mesh portion 41.

The configuration of the fitting grooves 25, 26 will be explained using Figures 4 and 5. As shown in Figure 4, the vertical fitting groove 25 is a recessed groove capable of accommodating the vertical edge member 42. The inner surface 251a, which is located on the indoor side of the fitting groove 25, has an engaging protrusion 252a that extends along the longitudinal direction and protrudes toward the outdoor side. The inner surface 251b, which is located on the outdoor side of the fitting groove 25, has an engaging protrusion 252b that extends along the longitudinal direction and protrudes toward the indoor side. The pair of engaging protrusions 252a, 252b face each other with a gap between them, narrowing the entrance of the fitting groove 25. The tip surfaces 253a, 253b of the engaging protrusions 252a, 252b are tapered and widen toward the outside of the fitting groove 25. The engaging protrusions 252a, 252b are positioned at the same depth in the fitting groove 25, which is the direction in which the vertical edge member 42 is inserted into the fitting groove 25. The bottom surface 254 of the fitting groove 25 is formed as a substantially flat surface.

As shown in Figure 5, the horizontal fitting groove 26 is a recessed groove capable of accommodating the horizontal edge member 43. The inner surface 261a, which is located on the indoor side of the fitting groove 26, has an engaging protrusion 262a that extends longitudinally and protrudes outdoors, similar to the fitting groove 25. The inner surface 261b, which is located on the outdoor side of the fitting groove 26, has an engaging protrusion 262b that extends longitudinally and protrudes indoors. The pair of engaging protrusions 262a, 262b face each other with a gap between them, narrowing the entrance to the fitting groove 26. The tip surfaces 263a, 263b of the engaging protrusions 262a, 262b are tapered and widen toward the outside of the fitting groove 26. The engaging protrusions 262a, 262b are located at the same position in the depth direction of the fitting groove 26, which is the direction in which the horizontal edge member 43 is inserted into the fitting groove 26. The bottom surface 264 of the fitting groove 26 is formed as a substantially flat surface.

The fitting groove 26 shown in Figure 5 is the fitting groove 26 arranged on the lower frame 22 side. The fitting groove 26 arranged on the upper frame 21 side has a pair of engagement protrusions 262a, 262b on the inner surfaces 261a, 261b, similar to the fitting groove 26 shown in Figure 5.

The positions of the inner surface 251a and engaging protrusion 252a in the fitting groove 25 in the front view direction are the same as the positions of the inner surface 261a and engaging protrusion 262a in the fitting groove 26 in the front view direction. The cross-sectional shape of the engaging protrusion 252a in the fitting groove 25 is the same as the cross-sectional shape of the engaging protrusion 262a in the fitting groove 26. The positions of the inner surface 251b and engaging protrusion 252b in the fitting groove 25 in the front view direction are the same as the positions of the inner surface 261b and engaging protrusion 262b in the fitting groove 26 in the front view direction. The cross-sectional shape of the engaging protrusion 252b in the fitting groove 25 is the same as the cross-sectional shape of the engaging protrusion 262b in the fitting groove 26.

The structure of the vertical edge members 42 will be explained using Figure 4. The left and right vertical edge members 42 on the vertical side have the same structure except that their cross-sectional shapes perpendicular to the longitudinal direction are symmetrical about an axis extending in the projection direction. Therefore, the following explanation will focus on the vertical edge member 42 on the vertical frame 23 side shown in Figure 4.

The vertical edge members 42 are attached to the frame 2 by fitting into the fitting grooves 25. All of the vertical edge members 42 are made of a hard material. For example, the vertical edge members 42 are made of hard polyvinyl chloride. For example, the vertical edge members 42 have a Shore hardness D of 65 to 85. The vertical edge members 42 have a pair of side plate portions 421a, 421b, a bottom plate portion 422, arcuate surfaces 423a, 423b, a push-in portion 424, a first protruding plate portion 425, a second protruding plate portion 426, a pair of inner engaging portions 428a, 428b, a first outer engaging portion 429b, and a second outer engaging portion 429a.

The side plate portion 421a extends in the left-right direction and is positioned on the indoor side of the screen door 4. The side plate portion 421b extends in the left-right direction and is positioned on the outdoor side of the screen door 4. The pair of side plate portions 421a, 421b are positioned parallel to each other and separated by a gap in the front direction. The gap between the pair of side plate portions 421a, 421b extends along the entire length of the vertical edge member 42. The bottom plate portion 422 extends in the front direction and connects the left ends of the pair of side plate portions 421a, 421b. The vertical edge member 42, which includes the pair of side plate portions 421a, 421b and the bottom plate portion 422, is formed into a roughly U-shape in side view that opens to the right. The outer surface from the side plate portion 421a to the bottom plate portion 422 is a smooth arc surface 423a. The outer surface from the side plate portion 421b to the bottom plate portion 422 is a smooth arc surface 423b.

The pushing portion 424 is used when removing the vertical edge member 42 that has been fitted into the fitting groove 25 from the fitting groove 25. The pushing portion 424 protrudes to the right from the right end of the side plate portion 421a. When the vertical edge member 42 is fitted into the fitting groove 25, the pushing portion 424 protrudes outside the fitting groove 25 further than the engaging protrusion 252a. The pushing portion 424 has a first portion 424a, a second portion 424b, and a third portion 424c. The first portion 424a slopes toward the exterior as it moves from the right end of the side plate portion 421a toward the outside of the fitting groove 25. When the vertical edge member 42 is fitted into the fitting groove 25, the first portion 424a slopes toward the engaging protrusion 252b as it moves further outside the fitting groove 25 than the engaging protrusion 252a. The second portion 424b extends from the tip of the first portion 424a in a direction toward the outside of the fitting groove 25. The third portion 424c extends from the tip of the second portion 424b at least toward the indoor side. In this embodiment, the third portion 424c extends from the tip of the second portion 424b toward both the indoor and outdoor sides.

Because the pushing portion 424 has the first portion 424a, the area facing the indoor side is longer than if the first portion 424a were not present and the second portion 424b extended from the right end of the side panel portion 421a toward the outside of the fitting groove 25. When pushing the pushing portion 424 toward the outdoors from the indoor side, the contact length between the finger and the pushing portion 424 is increased, allowing the pushing portion 424 to be firmly pushed outdoors. The third portion 424c, which extends indoors from the tip of the second portion 424b, is longer, increasing the area facing the inside of the fitting groove 25. When removing the vertical edge member 42 from the inside to the outside of the fitting groove 25, the contact length between the finger and the pushing portion 424 is increased, allowing the finger to firmly hook onto the pushing portion 424 and easily apply force in the removal direction.

The horizontal length of the pushing portion 424, i.e., the horizontal length from the left end of the first portion 424a to the right end of the third portion 424c, is preferably 3 mm or more, and more preferably 5 mm or more. If the horizontal length of the pushing portion 424 is 3 mm or more, the pushing portion 424 can be firmly pushed into the outdoor side from the indoor side.

The first protruding plate portion 425 extends from the inner surface of the indoor side plate portion 421a toward the outdoor side plate portion 421b, forming a first gap 430 along the longitudinal direction between it and the side plate portion 421b. The second protruding plate portion 426 extends from the inner surface of the bottom plate portion 422 toward the first protruding plate portion 425, forming a second gap 431 along the longitudinal direction between it and the first protruding plate portion 425. A space 432 is formed inside the vertical edge member 42, surrounded by the indoor side plate portion 421a, the bottom plate portion 422, the first protruding plate portion 425, and the second protruding plate portion 426.

The width of the second gap 431 between the first protruding plate portion 425 and the second protruding plate portion 426 is large enough to allow the flexible member 412b of the tape portion 412 to be inserted, but not allowing the locking member 412a to pass through. The locking member 412a of the tape portion 412 on the vertical side of the mesh portion 41 is accommodated in the space 432 from one longitudinal end side of the vertical edge member 42. The locking member 412a locks onto the second protruding plate portion 426 from the indoor side. The flexible member 412b is inserted sequentially through the second gap 431 and the first gap 430 and pulled out to the outside of the vertical edge member 42. The vertical edge member 42 is attached in an engaged state to the vertical side edge portion of the mesh portion 41.

The inner engagement portion 428a is located on the outer surface of the intersection between the side plate portion 421a and the arc surface 423a, and extends along the longitudinal direction. The inner engagement portion 428b is located on the outer surface of the intersection between the side plate portion 421b and the arc surface 423b, and extends along the longitudinal direction. The inner engagement portion 428a and the inner engagement portion 428b are located at the same position in the left-right direction. The maximum distance in the prospective direction between the inner engagement portion 428a and the inner engagement portion 428b is longer than the minimum distance in the prospective direction between the engagement protrusions 252a and 252b within the fitting groove 25. The distance between the indoor side surface of the side plate portion 421a and the outdoor side surface of the side plate portion 421b is less than the minimum distance in the prospective direction between the engagement protrusions 252a and 252b within the fitting groove 25. When the vertical edge member 42 is inserted into the fitting groove 25, the inner engagement portions 428a, 428b elastically overcome the engagement protrusions 252a, 252b inside the fitting groove 25, and when they engage with the engagement protrusions 252a, 252b from the inside of the fitting groove 25, the vertical edge member 42 is held within the fitting groove 25.

The distance between the leftmost end of the vertical edge member 42 and the inner engagement portions 428a, 428b is shorter than the distance from the bottom surface 254 of the fitting groove 25 to the engagement protrusions 252a, 252b. When the vertical edge member 42 is inserted into the fitting groove 25 and the inner engagement portions 428a, 428b engage with the engagement protrusions 252a, 252b from the inside of the fitting groove 25, the vertical edge member 42 does not come into contact with the bottom surface 254, and is held within the fitting groove 25 away from the bottom surface 254.

The second outer engagement portion 429a protrudes indoors from the intersection of the side plate portion 421a and the first portion 424a. The second outer engagement portion 429a extends indoors. The forward position of the tip of the second outer engagement portion 429a is closer to the indoor side than the indoor side surface of the side plate portion 421a. When the vertical edge member 42 is fitted into the fitting groove 25, the indoor-side tip of the second outer engagement portion 429a is located indoors than the tip surface 253a of the engagement protrusion 252a. When the vertical edge member 42 is fitted into the fitting groove 25, the second outer engagement portion 429a can engage with the engagement protrusion 252a from outside the fitting groove 25.

The first outer engagement portion 429b protrudes toward the exterior from the right end of the side plate portion 421b. The left-right position of the first outer engagement portion 429b is the same as the left-right position of the second outer engagement portion 429a. The first outer engagement portion 429b extends toward the exterior. The forward position of the tip of the first outer engagement portion 429b is closer to the exterior than the exterior side surface of the side plate portion 421b. When the vertical edge member 42 is fitted into the fitting groove 25, the outdoor-side tip of the first outer engagement portion 429b is located closer to the exterior than the tip surface 253b of the engagement protrusion 252b. When the vertical edge member 42 is fitted into the fitting groove 25, the first outer engagement portion 429b can engage with the engagement protrusion 252b from outside the fitting groove 25. The entire vertical edge member 42 is formed from a hard material. The vertical edge member 42 is easily fitted into and removed from the fitting groove 25 while minimizing the effects of temperature, such as hardening at low temperatures.

The position regulating portion 42A regulates the front-view position of the mesh portion main body 411 of the mesh portion 41 pulled out from the vertical edge member 42. The position regulating portion 42A is provided on the right end side of the third portion 424c of the vertical edge member 42. The position regulating portion 42A extends from the third portion 424c toward the outdoor side. The outdoor-side tip of the position regulating portion 42A is located further outdoors than the first outer engagement portion 429b of the vertical edge member 42, and further indoors than the inner surface 251b of the vertical frame 23 when the vertical edge member 42 is fitted into the fitting groove 25. When the vertical edge member 42 is fitted into the fitting groove 25, the position regulating portion 42A regulates the indoor-side front-view position of the entire vertical side relative to the left and right edges of the mesh portion main body 411, as shown in FIG. 2. When the vertical edge member 42 is fitted into the fitting groove 25, the inner surface 251b restricts the position of the entire vertical side relative to the left and right edges of the mesh main body 411 in the view direction toward the outdoors. The position of the left and right edges of the mesh main body 411 is restricted in the view direction between the position restricting portion 42A and the inner surface 251b.

The structure of the horizontal edge member 43 will be explained using Figure 5. The upper and lower horizontal edge members 43 have the same structure except that their cross-sectional shapes perpendicular to the longitudinal direction are symmetrical about an axis extending in the projection direction. Therefore, the following explanation will focus on the horizontal edge member 43 on the lower frame 22 side shown in Figure 5.

As shown in Figure 4, the locking member 412a is locked onto the second protruding plate portion 426 from the indoor side, and the flexible member 412b is pulled outward through the second gap 431 and the first gap 430. The left and right end faces of the horizontal edge member 43 face the vertical edge member 42 fitted into the fitting groove 25.

The cross-sectional shape of the horizontal edge member 43 perpendicular to the left-right direction is the same dimensions and identical to the cross-sectional shape of the vertical edge member 42 shown in Figure 4 perpendicular to the up-down direction. Because the cross-sectional shape of the horizontal edge member 43 perpendicular to the left-right direction is the same dimensions and identical to the cross-sectional shape of the vertical edge member 42 perpendicular to the up-down direction, management work is reduced, contributing to cost reductions.

As shown in Figure 5, the horizontal edge members 43 are attached to the frame 2 by fitting into the fitting grooves 26. All of the horizontal edge members 43 are made of a hard material. For example, the horizontal edge members 43 are made of the same hard polyvinyl chloride material as the vertical edge members 42. For example, the horizontal edge members 43 have a Shore hardness D of 65 to 85. The horizontal edge members 43 have a pair of side plate portions 521a, 521b, a bottom plate portion 522, arcuate surfaces 523a, 523b, a push-in portion 524, a first protruding plate portion 525, a second protruding plate portion 526, a pair of inner engaging portions 528a, 528b, a first outer engaging portion 529b, and a second outer engaging portion 529a.

The side plate portion 521a extends vertically and is positioned on the indoor side of the screen door 4. The side plate portion 521b extends vertically and is positioned on the outdoor side of the screen door 4. The pair of side plate portions 521a, 521b are positioned parallel to each other and separated by a gap in the front direction. The gap between the pair of side plate portions 521a, 521b extends along the entire length of the horizontal edge member 43. The bottom plate portion 522 extends vertically and connects the lower ends of the pair of side plate portions 521a, 521b. The horizontal edge member 43, which includes the pair of side plate portions 521a, 521b and the bottom plate portion 522, is formed into a roughly U-shape in side view that opens upward. The outer surface from the side plate portion 521a to the bottom plate portion 522 is a smooth arc surface 523a. The outer surface from the side plate portion 521b to the bottom plate portion 522 is a smooth arc surface 523b.

The push-in portion 524 is used when removing the horizontal edge member 43 that has been fitted into the fitting groove 26 from the fitting groove 26. The push-in portion 524 protrudes upward from the upper end of the side plate portion 521a. When the horizontal edge member 43 is fitted into the fitting groove 26, the push-in portion 524 protrudes outside the fitting groove 26 further than the engaging protrusion 262a. The push-in portion 524 has a first portion 524a, a second portion 524b, and a third portion 524c. The first portion 524a slopes toward the exterior as it moves from the upper end of the side plate portion 521a toward the outside of the fitting groove 26. When the horizontal edge member 43 is fitted into the fitting groove 26, the first portion 524a slopes toward the exterior as it moves toward the outside of the fitting groove 26 further than the engaging protrusion 262a. The second portion 524b extends from the tip of the first portion 524a in a direction toward the outside of the fitting groove 25. The third portion 524c extends from the tip of the second portion 524b at least toward the indoor side. In this embodiment, the third portion 524c extends from the tip of the second portion 524b toward both the indoor and outdoor sides.

When the pushing portion 524 has the first portion 524a, the area facing the indoor side is longer than when the first portion 524a is not present and the second portion 524b extends from the upper end of the side panel portion 521a in a direction toward the outside of the fitting groove 26. When pushing the pushing portion 524 toward the outdoors from the indoor side, the contact length between the finger and the pushing portion 524 is increased, allowing the pushing portion 524 to be firmly pushed outdoors. The third portion 524c extending indoors from the tip of the second portion 524b is longer, and the area facing the inside of the fitting groove 26 is longer. When removing the horizontal edge member 43 from the inside to the outside of the fitting groove 26, the contact length between the finger and the pushing portion 524 is increased, allowing force to be firmly applied to the pushing portion 524 in the removal direction. The vertical length of the pushing portion 524, that is, the vertical length from the lower end of the first portion 524a to the upper end of the third portion 524c, is preferably 3 mm or more, and more preferably 5 mm or more. If the vertical length of the pushing portion 524 is 3 mm or more, the pushing portion 524 can be firmly pushed into the outdoor side from the indoor side.

The first protruding plate portion 525 extends from the inner surface of the indoor side plate portion 521a toward the outdoor side plate portion 521b, forming a first gap 530 along the longitudinal direction between it and the side plate portion 521b. The second protruding plate portion 526 extends from the inner surface of the bottom plate portion 522 toward the first protruding plate portion 525, forming a second gap 531 along the longitudinal direction between it and the first protruding plate portion 525. A space 532 is formed inside the horizontal edge member 43, surrounded by the indoor side plate portion 521a, the bottom plate portion 522, the first protruding plate portion 525, and the second protruding plate portion 526.

The inner engagement portion 528a is located on the outer surface of the intersection between the side plate portion 521a and the arc surface 523a, and extends along the longitudinal direction. The inner engagement portion 528b is located on the outer surface of the intersection between the side plate portion 521b and the arc surface 523b, and extends along the longitudinal direction. The inner engagement portion 528a and the inner engagement portion 528b are located at the same position in the up-down direction. The maximum distance in the prospective direction between the inner engagement portion 528a and the inner engagement portion 528b is longer than the minimum distance in the prospective direction between the engagement protrusions 262a and 262b in the fitting groove 26. The distance between the indoor side surface of the side plate portion 521a and the outdoor side surface of the side plate portion 521b is equal to or less than the minimum distance in the prospective direction between the engagement protrusions 262a and 262b in the fitting groove 26. When the horizontal edge member 43 is inserted into the fitting groove 26, the inner engagement portions 528a, 528b elastically overcome the engagement protrusions 262a, 262b inside the fitting groove 26, and when they engage with the engagement protrusions 262a, 262b from the inside of the fitting groove 26, the horizontal edge member 43 is held within the fitting groove 26.

The distance between the lowest end of the horizontal edge member 43 and the inner engagement portions 528a, 528b is shorter than the distance from the bottom surface 264 of the fitting groove 26 to the engagement protrusions 262a, 262b. When the horizontal edge member 43 is inserted into the fitting groove 26 and the inner engagement portions 528a, 528b engage with the engagement protrusions 262a, 262b from the inside of the fitting groove 26, the horizontal edge member 43 does not come into contact with the bottom surface 264, and is held within the fitting groove 26 away from the bottom surface 264.

The second outer engagement portion 529a protrudes indoors from the intersection of the side plate portion 521a and the first portion 524a. The second outer engagement portion 529a extends indoors. The forward position of the tip of the second outer engagement portion 529a is closer to the indoor side than the indoor side surface of the side plate portion 521a. When the horizontal edge member 43 is fitted into the fitting groove 26, the indoor-side tip of the second outer engagement portion 529a is located indoors than the tip surface 263a of the engagement protrusion 262a. When the horizontal edge member 43 is fitted into the fitting groove 26, the second outer engagement portion 529a can engage with the engagement protrusion 262a from outside the fitting groove 26.

The first outer engagement portion 529b protrudes toward the exterior from the upper end of the side plate portion 521b. The vertical position of the first outer engagement portion 529b is the same as the vertical position of the second outer engagement portion 529a. The first outer engagement portion 529b extends toward the exterior. The forward position of the tip of the first outer engagement portion 529b is closer to the exterior than the exterior side surface of the side plate portion 521b. When the horizontal edge member 43 is fitted into the fitting groove 26, the outdoor tip of the first outer engagement portion 529b is located closer to the exterior than the tip surface 263b of the engagement protrusion 262b. When the horizontal edge member 43 is fitted into the fitting groove 26, the first outer engagement portion 529b engages with the engagement protrusion 262b from outside the fitting groove 26. The entire horizontal edge member 43 is formed from a hard material. The horizontal edge member 43 is easily fitted into and removed from the fitting groove 26 while being less susceptible to the effects of temperature, such as hardening at low temperatures.

The position regulating portion 43A regulates the front-facing position of the mesh portion main body 411 of the mesh portion 41 pulled out of the fitting groove 26. The position regulating portion 43A is provided on the upper end side of the third portion 524c of the horizontal edge member 43. The position regulating portion 43A extends from the third portion 524c toward the outdoor side. The outdoor-side tip of the position regulating portion 43A is located outdoors relative to the first outer engagement portion 529b of the horizontal edge member 43, and indoors relative to the inner surface 261b of the lower frame 22 when the horizontal edge member 43 is fitted into the fitting groove 26. The outdoor-side tip of the position regulating portion 43A is located the same as the outdoor-side tip of the position regulating portion 42A. When the horizontal edge member 43 is fitted into the fitting groove 26, the position regulating portion 43A regulates the indoor-side front-facing position of the entire lateral side relative to the vicinity of the vertical edges of the mesh portion main body 411, as shown in FIG. 1. When the horizontal edge member 43 is fitted into the fitting groove 26, the inner surface 261b restricts the position of the entire lateral side relative to the vertical edge of the mesh main body 411 in the forward direction toward the outdoors. The position of the vertical edge of the mesh main body 411 in the forward direction is restricted between the position restricting portion 43A and the inner surface 261b.

The positions of the inner surface 251b and the inner surface 261b in the front view direction are the same. The position of the outdoor-facing tip of the position restriction portion 43A is the same as the position of the outdoor-facing tip of the position restriction portion 42A. The inner surface 251b, the inner surface 261b, the position restriction portion 42A, and the position restriction portion 43A make it possible to align the position of the mesh portion main body 411 in the front view direction across the entire vertical and horizontal sides.

The method for attaching the screen door 4 to the frame body 2 will be explained with reference to Figures 1 to 7. Before attaching the screen door 4 to the frame body 2, as shown in Figure 3, the vertical edge members 42 are engaged with and attached to the mesh portion 41, and the horizontal edge members 43 are separate from the mesh portion 41.

From this state, the vertical edge member 42 is attached to the fitting grooves 25 of the vertical frames 23, 24. The method for attaching the vertical edge member 42 to the vertical frames 23, 24 is similar, so the method for attaching it to the vertical frame 23 will be explained below using Figure 6.

As shown in Figure 6, the vertical edge members 42 attached to the mesh portion 41 are inserted into the mating grooves 25 of the vertical frames 23, with the side panel portions 421a having the push-in portions 424 positioned on the indoor side. While Figure 6 only shows the vertical frame 23 side, the same applies to the vertical frame 24. When inserting the vertical edge members 42 into the mating grooves 25, the vertical edge members 42 are inserted in the direction of arrow T1 with the push-in portions 424 tilted toward the outdoor side, and the outdoor-side inner engagement portion 428b engages with the engagement protrusion 252b from the inside of the mating groove 25. The inner engagement portion 428a contacts the tip surface 253a of the engagement protrusion 252a. The push-in portions 424 are then pushed toward the mating groove 25, and the vertical edge member 42 is rotated in the direction of arrow T2, which is clockwise, around the point of contact between the inner engagement portion 428b and the engagement protrusion 252b. The inner engaging portion 428a of the vertical edge member 42 elastically moves over the engaging protrusion 252a and engages with the engaging protrusion 252a from the inside of the fitting groove 25, completing the attachment of the vertical edge member 42 to the fitting groove 25 as shown in Figure 2.

When the vertical edge member 42 is attached to the fitting groove 25, as shown in Figure 5, the horizontal edge of the mesh section 41 is inserted into the fitting groove 26. Specifically, the locking member 412a is positioned on the indoor side of the bottom surface 264 of the fitting groove 26, the flexible member 412b is positioned on the outdoor side of the bottom surface 264, and the mesh section main body 411 is pulled out from the fitting groove 26 toward the indoor side, that is, the indoor side, 261b, along the tip surface 263b of the outdoor-side engaging protrusion 262b and the inner surface 261b.

The vertical edge members 42 that fit into the vertical frames 23, 24 are combined vertically relative to the horizontal edge members 43 that fit into the upper frame 21 and lower frame 22, so the fitting grooves 26 of the upper frame 21 and lower frame 22 restrict the position where the horizontal edge members 43 fit between the vertical frames 23, 24. Because the fitting position of the horizontal edge members 43 is restricted between the vertical frames 23, 24, it is possible to prevent difficulty in fitting the horizontal edge members 43 into the fitting grooves 26 of the upper frame 21 and lower frame 22.

When inserting the vertical edge member 42 into the fitting groove 25, for example, the third portion 424c of the push-in portion 424 is pushed in from the outside. Because the third portion 424c extends from the tip of the second portion 424b toward both the outdoor and indoor sides, it has a large contact area, allowing the vertical edge member 42 to be pushed in stably. Because the first portion 424a of the push-in portion 424 is inclined toward the outdoor side, the second portion 424b and the third portion 424c are closer to the center in the projection direction, allowing the vertical edge member 42 to be pushed in more stably. When the push-in portion 424, located on the indoor side, is pushed in, the momentum released from the resistance caused by the inner engaging portion 428a elastically overcoming the engaging protrusion 252a may cause the bottom plate portion 422 to reach the bottom surface 254 of the frame body 2, potentially resulting in deformation. A second outer engagement portion 429a is provided at the base of the push-in portion 424, which prevents the bottom plate portion 422 from reaching the bottom surface 254 of the frame body 2 when it engages with the engagement protrusion 252a from the outside of the fitting groove 25.

When the screen door 4 is subjected to wind pressure from the outdoors, a force is applied to the vertical edge member 42 on the vertical frame 23 side, causing the push-in portion 424 to rotate in a direction that moves the push-in portion 424 toward the inside of the fitting groove 25 within the fitting groove 25. Even in this case, when the second outer engagement portion 429a engages with the engagement protrusion 252a from the outside of the fitting groove 25, the push-in portion 424 side can be prevented from rotating. The wind pressure causes the outdoor-side inner engagement portion 428b to immediately climb over the outdoor-side engagement protrusion 252b of the fitting groove 25, preventing the vertical edge member 42 from unintentionally coming out of the fitting groove 25.

At this stage, the horizontal edge members 43 are not attached to the mesh portion 41, so the horizontal edge members 43 do not impede workability and the vertical edge members 42 can be easily and stably attached to the fitting grooves 25. The hard vertical edge members 42 fit firmly into the fitting grooves 25, preventing the vertical edge members 42 from lifting up and becoming detached unintentionally or causing slack in the screen door 4.

After the vertical edge members 42 are attached to the fitting grooves 25, the horizontal edge members 43 are attached to the fitting grooves 26 of the upper frame 21 and lower frame 22, as shown in Figure 5. The method for attaching the horizontal edge members 43 to the upper frame 21 and lower frame 22 is similar, so the method for attaching them to the lower frame 22 will be explained below using Figure 5.

The vertical frames 23, 24 into which the vertical edge member 42 fits are combined vertically with the upper and lower frames 21, 22, with the horizontal edges of the mesh portion 41 inserted into the fitting grooves 26. This means that the fitting grooves 26 of the horizontal edge member 43 are open and exposed to the inside of the fitting 1 in the vertical direction without interfering with the vertical frames 23, 24. As a result, when the horizontal edge member 43 is inserted into the fitting grooves 26, it can be easily installed without interfering with the vertical frames 23, 24.

When inserting the horizontal edge member 43 into the fitting groove 26, as shown in Figure 7, similar to the vertical edge member 42, the pushing portion 524 is first tilted toward the exterior and the horizontal edge member 43 is inserted toward the fitting groove 26 in the direction of arrow T3, so that the exterior-side inner engaging portion 528b engages with the engaging protrusion 262b from the inside of the fitting groove 26. The inner engaging portion 528a contacts the tip surface 263a of the engaging protrusion 262a. The pushing portion 524 is then further pushed toward the fitting groove 26, and the horizontal edge member 43 is rotated clockwise in the direction of arrow T4 around the point of contact between the inner engaging portion 528b and the engaging protrusion 262b. The inner engaging portion 528a of the horizontal edge member 43 elastically moves over the engaging protrusion 262a and engages with the engaging protrusion 262a from the inside of the fitting groove 26, completing the attachment of the horizontal edge member 43 to the fitting groove 26 as shown in Figure 1.

When inserting the horizontal edge member 43 into the fitting groove 26, for example, the third portion 524c of the pushing portion 524 is pushed into the fitting groove 26 from the outside. The third portion 524c extends from the tip of the second portion 524b toward both the indoor and outdoor sides, providing a large contact area and allowing the horizontal edge member 43 to be pushed in stably. The first portion 524a of the pushing portion 524 is tilted toward the outdoor side, so the second portion 524b and the third portion 524c are closer to the center in the projection direction, allowing the horizontal edge member 43 to be pushed in more stably. When the pushing portion 524, located on the indoor side, is pushed in, the momentum released from the resistance caused by the inner engaging portion 528a elastically overcoming the engaging protrusion 262a may cause the bottom plate portion 522 to reach the bottom surface 264 of the frame body 2, potentially resulting in deformation. A second outer engagement portion 529a is provided at the base of the push-in portion 524, which prevents the bottom plate portion 522 from reaching the bottom surface 264 of the frame body 2 when it engages with the engagement protrusion 262a from the outside of the fitting groove 26.

When the screen door 4 is subjected to wind pressure from the outdoors, a force is applied to the horizontal edge member 43 that rotates the push-in portion 524 side in a direction that moves it indoors within the fitting groove 26. Even in this case, when the second outer engagement portion 529a engages with the engagement protrusion 262a from the outside of the fitting groove 26, the rotation of the push-in portion 524 side can be prevented. The wind pressure causes the outdoor-side inner engagement portion 528b to immediately climb over the outdoor-side engagement protrusion 262b of the fitting groove 26, preventing the horizontal edge member 43 from unintentionally coming out of the fitting groove 26.

As explained above, the vertical edge members 42 and horizontal edge members 43 are attached to the frame body 2, and the screen door 4 is then stretched. The horizontal edge members 43 are separate from the mesh portion 41 and can be easily fitted into the fitting groove 26. Therefore, after the vertical edge members 42 are attached to the fitting groove 25, the mesh portion 41 can be easily fitted into the fitting groove 26.

The method for removing the screen door 4 from the fitting groove 26 of the frame body 2 will be explained with reference to Figures 1 and 8. The vertical edge members 42 and horizontal edge members 43 have the same cross-sectional shape, and the method for removing the vertical edge members 42 from the vertical frames 23, 24 is similar to the method for removing the horizontal edge members 43 from the upper frame 21 and lower frame 22. Therefore, the method for removing the horizontal edge member 43 from the lower frame 22 will be explained.

As shown in Figure 1, the pushing portion 524 of the horizontal edge member 43 is pushed in the direction of arrow T5 from the indoor side to the outdoor side. It is preferable that the pushing portion 524 be pushed in from either the left or right end. When the pushing portion 524 is pushed in toward the outdoor side, as shown in Figure 8, the horizontal edge member 43 is rotated counterclockwise in the figure so that the pushing portion 524 tilts toward the outdoor side, and the indoor inner engagement portion 528a disengages from the engagement protrusion 262a.

If the horizontal edge member 43 does not have a first outer engagement portion 529b on the outdoor side, the arcuate surface 523b and side plate portion 521b may sink toward the bottom surface 264 of the fitting groove 26 when the push-in portion 524 is pushed toward the outdoor side and the horizontal edge member 43 is rotated counterclockwise. In this case, the tip of the side plate portion 521b may engage with the engagement protrusion 262b from the inside of the fitting groove 26, making it impossible to remove the horizontal edge member 43 from the fitting groove 26. In this embodiment, when the push-in portion 524 is pushed toward the outdoor side, the first outer engagement portion 529b on the outdoor side engages with the engagement protrusion 262b from the outside of the fitting groove 26, thereby preventing the horizontal edge member 43 from sinking toward the bottom surface 264 of the fitting groove 26. When the first outer engagement portion 529b engages with the engagement protrusion 262b from the outside of the fitting groove 26, the first outer engagement portion 529b acts as a fulcrum, making it easier for the horizontal edge member 43 to rotate counterclockwise, effectively transmitting a force in the direction of disengagement of the inner engagement portion 528a from the engagement protrusion 262a.

When the inner engaging portion 528a is disengaged from the engaging protrusion 262a, the pushing portion 524 is further rotated toward the exterior while the horizontal edge member 43 is pulled up in the direction of arrow T6 outside the fitting groove 26. When the horizontal edge member 43 is pulled up into the fitting groove 26, either the left or right end of the horizontal edge member 43 disengages from the fitting groove 26. By pulling the horizontal edge member 43 that has been released from the fitting groove 26 up to either the right or left, the entire horizontal edge member 43 can be removed from the fitting groove 26.

As explained above, according to the fitting 1 of this embodiment, the vertical edge members 42 and horizontal edge members 43 have push-in portions 424, 524 that protrude further outward from the mating grooves 25, 26 than the indoor-side engaging protrusions 252a, 262a, and first outer engaging portions 429b, 529b that engage with the outdoor-side engaging protrusions 252b, 262b from the outside of the mating grooves 25, 26. This improves the ease of removal of the attachments, i.e., the vertical edge members 42 and horizontal edge members 43, regardless of the shape of the frame body 2.

Preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings. It goes without saying that the present disclosure is not limited to these examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

For example, in the above embodiment, the vertical edge member 42 and the horizontal edge member 43 have the same cross-sectional shape, and both the vertical edge member 42 and the horizontal edge member 43 have push-in portions 424, 524 that protrude further outward from the mating grooves 25, 26 than the indoor-side engaging protrusions 252a, 262a, and first outer engaging portions 429b, 529b that engage with the outdoor-side engaging protrusions 252b, 262b from the outside of the mating grooves 25, 26. However, this configuration is not limited to this, and only one of the vertical edge member 42 and the horizontal edge member 43 may have a push-in portion and a first outer engaging portion.

In the above embodiment, an example was given of a configuration in which, before the screen door 4 is attached to the frame body 2, the vertical edge members 42 are engaged with and attached to the mesh portion 41, and the horizontal edge members 43 are separate from the mesh portion 41. However, this configuration is not limited to this, and a configuration in which, before the screen door 4 is attached to the frame body 2, the horizontal edge members 43 are engaged with and attached to the mesh portion 41, and the vertical edge members 42 are separate from the mesh portion 41, may also be used. In this case, it is preferable that the frame body 2 be assembled in a so-called horizontal-through horizontal manner, in which the upper frame 21 and lower frame 22 are attached to the vertical frame 23 and vertical frame 24, respectively.
