[0009] Hereinafter, embodiments of the screen door and fittings with screen door of the present disclosure will be described with reference to Figures 1 to 9. In the following drawings, the scale and number of each structure may differ from the actual structure in order to make each component of the screen door and fittings with screen door easier to understand.

[0010] As shown in Figures 1 and 2, the screen door fitting 1 comprises a rectangular frame body 2 that is attached to an opening (not shown) formed in the wall of a building, and a screen door 3 that is attached to the frame body 2 so as to be able to open and close. In the following description, the screen door fitting 1 will be simply referred to as the fitting 1. In other words, the fitting 1 corresponds to the screen door fitting 1. As an example, the fitting 1 is provided as a fitting having a frame body 2 made of a metal material such as aluminum and a resin material such as polyvinyl chloride.

[0011] When viewing the door 1 attached to the opening of a building from the indoor side, the direction that is up and down is referred to as the up-down direction, and the direction that is left and right is referred to as the left-right direction. In the door 1, the direction perpendicular to the left-right direction and along the indoor-outdoor direction is referred to as the prospective direction.

[0012] The frame body 2 has a pair of upper and lower frames 21 and 22 that are arranged opposite each other in the vertical direction of the frame body 2 and extend in the left-right direction, and a pair of vertical frames 23 and 24 that are arranged opposite each other in the left-right direction and extend in the up-down direction. 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 attached to the vertical frames 23 and 24 at both ends in the left-right direction, respectively, and the frame body 2 is framed in a rectangular shape. The materials of the upper and lower frames 21 and 22 and the vertical frames 23 and 24 are not particularly limited, and extruded materials such as aluminum or resin are used.

[0013] The upper frame 21 and the lower frame 22 each have a horizontal fitting groove 25 formed as a recessed groove in each of their projection surfaces 21a, 22a (not shown). The horizontal fitting groove 25 extends in the left-right direction and is formed over the entire length of each of the upper frame 21 and the lower frame 22. The vertical frames 23, 24 each have a vertical fitting groove 26 formed as a recess in each of their projection surfaces 23a, 24a (not shown). The vertical fitting groove 26 extends in the up-down direction and is formed over the entire length of each of the vertical frames 23, 24. The horizontal fitting groove 25 and the vertical fitting groove 26 are arranged at the same position in the projection direction and are connected to each other around the four periphery of the frame body 2.

[0014] As shown in FIG. 1 , the screen door 3 comprises a rectangular mesh portion 31, tape portions 32 attached to the four peripheral edges 311 of the mesh portion 31, a pair of screen door attachments 33, 33 arranged on the left and right edges of the mesh portion 31, extending vertically and integrally engaged with the mesh portion 31, and a pair of add-on screen door attachments 34, 34 arranged on the top and bottom edges of the mesh portion 31, extending horizontally and attached to the mesh portion 31 when the screen door 3 is installed. The screen door attachment 33 corresponds to the vertical edge member. The add-on screen door attachment 34 corresponds to the horizontal edge member. The four peripheral edges 311 correspond to the outer edges of the mesh portion 31.

[0015] The screen door 3 has screen door attachments 33, 33 that are removably fitted into the vertical fitting grooves 26, 26 of the vertical frames 23, 24. The screen door 3 has retrofit screen door attachments 34, 34 that are removably fitted into the horizontal fitting grooves 25, 25 of the upper frame 21 and the lower frame 22. The screen door 3 is a frameless screen door whose four peripheral edges 311 are removably attached to the frame body 2 and which fits snugly into the frame body 2.

[0016] When the screen door 3 is not attached to the frame 2, the add-on screen door attachment 34 and the other components of the screen door 3 are separate. Because the add-on screen door attachment 34 is separate, the screen door 3 does not have the add-on screen door attachments 34, 34 attached before the screen door 3 is attached to the frame 2 or after the screen door 3 is removed from the frame 2. This allows for less packaging by wrapping the screen door 3 around one of the screen door attachments 33, 33. When not attached to the tape portion 32, the add-on screen door attachment 34 is provided as a rod-shaped member. This allows for space-saving storage and transportation of each component of the screen door 3.

[0017] 3, the tape portion 32 is sewn around the entire four peripheral edges 311 of the mesh portion 31. The tape portion 32 has a fastening portion 321 and a flexible portion 322. As an example, the tape portion 32 is made up of a tape half of a fastener having teeth arranged on the exterior side as the fastening portion 321.

[0018] The locking portions 321 are formed to have a greater thickness in the front direction than the flexible portions 322. The locking portions 321 arranged on the left and right sides of the net portion 31 are formed over the entire length of the net portion 31 in the vertical direction. The locking portions 321 arranged on the upper and lower sides of the net portion 31 do not extend over the entire length of the net portion 31 in the horizontal direction, and a predetermined gap is provided between the locking portions 321 in the vertical direction so that the vertical tape portion 32 can be inserted into the screen attachment 33, as will be described later.

[0019] The flexible portion 322 is provided, for example, as a flexible cloth material. The flexible portion 322 extends from the mesh portion 31 on both sides in the up-down direction and both sides in the left-right direction. The flexible portion 322 extends to the four peripheral edges of the mesh portion 31. The flexible portion 322 is sewn to the mesh portion 31. The flexible portion 322 may be glued to the mesh portion 31 or may be welded to the mesh portion 31.

[0020] The configuration of the vertical fitting groove 26 will be described with reference to Figure 4. The vertical fitting groove 26 is formed as a recessed groove capable of accommodating the screen door attachment 33. An inner surface 261a disposed on the indoor side of the vertical fitting groove 26 has an engaging protrusion 262a extending along the longitudinal direction and protruding toward the outdoor side. An inner surface 261b disposed on the outdoor side of the vertical fitting groove 26 has an engaging protrusion 262b extending along the longitudinal direction and protruding toward the indoor side. The pair of engaging protrusions 262a, 262b are formed to protrude facing each other with a gap between them, narrowing the entrance 263 of the vertical fitting groove 26. Tip surfaces 264a, 264b of the engaging protrusions 262a, 262b are formed in a tapered shape that widens toward the outside of the vertical fitting groove 26. The engaging protrusions 262a and 262b are arranged so that their positions are approximately aligned in the depth direction (left-right direction in FIG. 4) of the vertical fitting groove 26, which is the insertion direction of the screen door attachment 33 into the vertical fitting groove 26. A bottom surface 265 within the vertical fitting groove 26 is formed into a substantially flat surface.

[0021] The vertical fitting groove 26 shown in Fig. 4 is the vertical fitting groove 26 arranged on the vertical frame 23 side. The vertical fitting groove 26 arranged on the vertical frame 24 side has a pair of engaging protrusions 262a, 262b on inner surfaces 261a, 261b, similar to Fig. 4.

[0022] As shown in FIG. 5 , the horizontal fitting groove 25 is formed as a recessed groove capable of accommodating the retrofit screen attachment 34 and a temporary fastening member (described later). Similar to the vertical fitting groove 26, the inner surface 251a, which is located on the outdoor side of the horizontal fitting groove 25, has an engaging protrusion 252a that extends along the longitudinal direction and protrudes toward the indoor side. The inner surface 251b, which is located on the indoor side of the horizontal fitting groove 25, has an engaging protrusion 252b that extends along the longitudinal direction and protrudes toward the outdoor side. The pair of engaging protrusions 252a, 252b are formed to protrude facing each other with a gap between them, narrowing the entrance 253 of the horizontal fitting groove 25. The tip surfaces 254a, 254b of the engaging protrusions 252a, 252b are formed in a tapered shape that widens toward the outside of the horizontal fitting groove 25. The engaging protrusions 252a and 252b are arranged so that their positions are approximately aligned in the depth direction (vertical direction in FIG. 5) of the horizontal fitting groove 25, which is the insertion direction of the retrofit screen door attachment 34 into the horizontal fitting groove 25. The bottom surface 255 within the horizontal fitting groove 25 is formed into a substantially flat surface.

[0023] The horizontal fitting groove 25 shown in Fig. 5 is the horizontal fitting groove 25 arranged on the upper frame 21 side. The horizontal fitting groove 25 arranged on the lower frame 22 side has a pair of engaging protrusions 252a, 252b on inner surfaces 251a, 251b, similar to the horizontal fitting groove 25 shown in Fig. 5.

[0024] The positions of the inner side surface 251a and the engaging protrusion 252a in the horizontal fitting groove 25 in the front direction are the same as the positions of the inner side surface 261b and the engaging protrusion 262b in the vertical fitting groove 26 in the front direction. The cross-sectional shape of the engaging protrusion 252a in the horizontal fitting groove 25 is the same as the cross-sectional shape of the engaging protrusion 262b in the vertical fitting groove 26. The positions of the inner side surface 251b and the engaging protrusion 252b in the horizontal fitting groove 25 in the front direction are the same as the positions of the inner side surface 261a and the engaging protrusion 262a in the vertical fitting groove 26. The cross-sectional shape of the engaging protrusion 252b in the horizontal fitting groove 25 is the same as the cross-sectional shape of the engaging protrusion 262a in the vertical fitting groove 26.

[0025] The structure of the screen door attachment 33 will be explained using Figures 2 and 4. As shown in Figure 2, the left and right screen door attachments 33, 33 on the vertical side are pre-attached to the left and right edges of the screen part 31, respectively, and are integrated with the screen part 31. The screen door attachments 33, 33 are fitted into the vertical fitting grooves 26, 26 and attached to the frame body 2. The screen door attachments 33, 33 have the same structure except that their cross-sectional shapes perpendicular to the longitudinal direction are line-symmetrical about an axis extending in the forward direction, and therefore, the following explanation will focus on the screen door attachment 33 on the vertical frame 23 side shown in Figure 4.

[0026] The screen door attachment 33 has a pair of side plate portions 331a, 331b, a bottom plate portion 332, arcuate surfaces 333a, 333b, a push-in portion 334, a first protruding plate portion 335, a second protruding plate portion 336, a pair of protrusions 337a, 337b, a first engaging portion 338a, and a second engaging portion 338b. The screen door attachment 33 is made entirely of a hard material. For example, the screen door attachment 33 is made of hard polyvinyl chloride.

[0027] The side plate 331a extends in the left-right direction and is located on the indoor side of the screen door 3. The side plate 331b extends in the left-right direction and is located on the outdoor side of the screen door 3. The pair of side plates 331a, 331b are arranged parallel to each other and separated by a gap in the front direction. The gap between the pair of side plates 331a, 331b spans the entire length of the screen door attachment 33. The bottom plate 332 extends in the front direction and connects the left ends of the pair of side plates 331a, 331b. The screen door attachment 33, which includes the pair of side plates 331a, 331b and the bottom plate 332, is formed into a generally U-shape in side view, opening to the right. The outer surface from the side plate 331a to the bottom plate 332 forms a smoothly arcuate surface 333a. The outer surface from the side plate 331b to the bottom plate 332 forms a smoothly arcuate surface 333b.

[0028] The push-in portion 334 is used when attaching and detaching the screen door attachment 33 fitted into the vertical fitting groove 26. The push-in portion 334 protrudes to the right from the right end portion of the side plate portion 331a. When the screen door attachment 33 is fitted into the vertical fitting groove 26, the push-in portion 334 protrudes outside the vertical fitting groove 26 further than the engaging protrusion 262a.

[0029] The first protruding plate portion 335 extends from the inner surface of the indoor-side side plate portion 331a toward the outdoor-side side plate portion 331b, forming a first gap 335a along the longitudinal direction between it and the side plate portion 331b. The second protruding plate portion 336 extends from the inner surface of the bottom plate portion 332 toward the first protruding plate portion 335, forming a second gap 336a along the longitudinal direction between it and the first protruding plate portion 335. A space 339 is formed inside the screen door attachment 33, surrounded by the indoor-side side plate portion 331a, the bottom plate portion 332, the first protruding plate portion 335, and the second protruding plate portion 336.

[0030] The width of the second gap 336a between the first projecting plate portion 335 and the second projecting plate portion 336 is such that the flexible portion 322 of the tape portion 32 can be inserted but the locking portion 321 cannot pass through. The locking portion 321 of the tape portion 32 on the vertical side of the mesh portion 31 is accommodated in the space 339 from one longitudinal end side of the screen door attachment 33. The locking portion 321 is locked to the second projecting plate portion 336 from the indoor side. The flexible portion 322 is inserted sequentially through the second gap 336a and the first gap 335a and pulled out to the outside of the screen door attachment 33. The screen door attachment 33 is attached in an engaged state to the vertical side edge of the mesh portion 31.

[0031] The protrusion 337a is located on the outer surface of the intersection between the side plate portion 331a and the arcuate surface 333a and extends along the longitudinal direction. The protrusion 337b is located on the outer surface of the intersection between the side plate portion 331b and the arcuate surface 333b and extends along the longitudinal direction. The left-right positions of the protrusions 337a and 337b are the same. The maximum distance in the front direction between the protrusions 337a and 337b is longer than the minimum distance in the front direction between the engaging protrusions 262a and 262b in the vertical fitting groove 26. The distance between the indoor side surface of the side plate portion 331a and the outdoor side surface of the side plate portion 331b is equal to or less than the minimum distance in the front direction between the engaging protrusions 262a and 262b in the vertical fitting groove 26. When the screen door attachment 33 is fitted into the vertical fitting groove 26, the protrusions 337a, 337b elastically overcome the engaging protrusions 262a, 262b in the vertical fitting groove 26, and when they engage with the engaging protrusions 262a, 262b from the inside of the vertical fitting groove 26, the screen door attachment 33 is held in the vertical fitting groove 26.

[0032] The distance between the leftmost end of screen door attachment 33 and protrusions 337a, 337b is shorter than the distance from bottom surface 265 of vertical fitting groove 26 to engaging protrusions 262a, 262b. When screen door attachment 33 is fitted into vertical fitting groove 26 and protrusions 337a, 337b engage with engaging protrusions 262a, 262b from the inside of vertical fitting groove 26, screen door attachment 33 does not come into contact with bottom surface 265, and screen door attachment 33 is held within vertical fitting groove 26 away from bottom surface 265.

[0033] The first engagement portion 338a protrudes indoors from the right end of the side plate portion 331a. The first engagement portion 338a extends indoors. The front end of the first engagement portion 338a is located closer to the indoor side than the indoor side surface of the side plate portion 331a. When the screen door attachment 33 is fitted into the vertical fitting groove 26, the indoor-side tip of the first engagement portion 338a is located closer to the indoor side than the tip surface 264a of the engagement protrusion 262a. When the screen door attachment 33 is fitted into the vertical fitting groove 26, the first engagement portion 338a abuts against the outside of the engagement protrusion 262a.

[0034] The second engagement portion 338b protrudes toward the outdoor side from the right end of the side plate portion 331b. The left-right position of the second engagement portion 338b is the same as the left-right position of the first engagement portion 338a. The second engagement portion 338b extends toward the outdoor side. The front end of the second engagement portion 338b is located closer to the outdoor side than the outdoor-facing side surface of the side plate portion 331b. When the screen door attachment 33 is fitted into the vertical fitting groove 26, the outdoor-side tip of the second engagement portion 338b is located closer to the outdoor side than the tip surface 264b of the engagement protrusion 262b. When the screen door attachment 33 is fitted into the vertical fitting groove 26, the second engagement portion 338b abuts against the outside of the engagement protrusion 262b. The entire screen door attachment 33 is formed from a hard material.

[0035] The structure of the after-market screen door attachment 34 will be explained using Figure 5. The upper and lower after-market screen door attachments 34, 34 have the same structure except that the cross-sectional shapes perpendicular to the longitudinal direction are symmetrical about an axis extending in the forward direction, so the following will explain the after-market screen door attachment 34 on the upper frame 21 side shown in Figure 5.

[0036] 4, the locking portion 321 is locked onto the second projecting plate portion 336 from the indoor side, and the flexible portion 322 is pulled outward through the second gap 336a and the first gap 335a. The left and right end faces of the add-on screen attachment 34 face the screen attachment 33 fitted into the vertical fitting groove 26.

[0037] As shown in Figure 5, the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25 and attached to the frame body 2. The retrofit screen door attachment 34 is made entirely of a hard material. As an example, the retrofit screen door attachment 34 is made of the same hard polyvinyl chloride as the screen door attachment 33. The retrofit screen door attachment 34 has a pair of side plate portions 341a, 341b, a bottom plate portion 342, arcuate surfaces 343a, 343b, a push-in portion 344, a first protruding plate portion 345, a second protruding plate portion 346, a pair of protrusions 347a, 347b, a first engaging portion 348a, and a second engaging portion 348b.

[0038] The side plate 341a extends vertically and is disposed on the outdoor side of the screen door 3. The side plate 341b extends vertically and is disposed on the indoor side of the screen door 3. The pair of side plates 341a, 341b are disposed parallel to each other and separated by a gap in the front direction. The gap between the pair of side plates 341a, 341b is provided over the entire length of the retrofit screen door attachment 34. The bottom plate 342 extends vertically and connects the upper ends of the pair of side plates 341a, 341b. The retrofit screen door attachment 34, which includes the pair of side plates 341a, 341b and the bottom plate 342, is formed into a generally U-shape in side view that opens downward. The outer surface from the side plate 341a to the bottom plate 342 forms a smooth arc surface 343a. The outer surface from the side plate portion 341b to the bottom plate portion 342 is a smooth arcuate surface 343b.

[0039] The push-in portion 344 is used when attaching and removing the retrofit screen door attachment 34 that is fitted into the horizontal fitting groove 25. The push-in portion 344 protrudes downward from the lower end of the side plate portion 341b. When the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25, the push-in portion 344 protrudes outside the horizontal fitting groove 25 further than the engaging protrusion 252b.

[0040] The protrusion 347a is located on the outer surface of the intersection between the side plate portion 341a and the arcuate surface 343a and extends along the longitudinal direction. The protrusion 347b is located on the outer surface of the intersection between the side plate portion 341b and the arcuate surface 343b and extends along the longitudinal direction. The protrusions 347a and 347b are positioned at the same vertical position. The maximum distance between the protrusions 347a and 347b in the front direction is longer than the minimum distance between the engaging protrusions 252a and 252b in the lateral fitting groove 25 in the front direction. The distance between the indoor side surface of the side plate portion 341a and the outdoor side surface of the side plate portion 341b is equal to or less than the minimum distance between the engaging protrusions 252a and 252b in the front direction in the lateral fitting groove 25. Therefore, when the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25, the protrusions 347a, 347b elastically overcome the engaging protrusions 252a, 252b in the horizontal fitting groove 25, and when they engage with the engaging protrusions 252a, 252b from the inside of the horizontal fitting groove 25, the retrofit screen door attachment 34 is held within the horizontal fitting groove 25.

[0041] The distance between the uppermost end of the retrofit screen door attachment 34 and the protrusions 347a, 347b is shorter than the distance from the bottom surface 255 of the horizontal fitting groove 25 to the engaging protrusions 252a, 252b. Therefore, when the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25 and the protrusions 347a, 347b engage with the engaging protrusions 252a, 252b from the inside of the horizontal fitting groove 25, the retrofit screen door attachment 34 does not come into contact with the bottom surface 255, and the retrofit screen door attachment 34 is held within the horizontal fitting groove 25 away from the bottom surface 255.

[0042] The first engagement portion 348a protrudes outdoors from the lower end of the side plate portion 341a. The first engagement portion 348a extends outdoors. The forward position of the tip of the first engagement portion 348a is closer to the outdoors than the outdoor side surface of the side plate portion 341a. When the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25, the outdoor-side tip of the first engagement portion 348a is positioned closer to the outdoors than the tip surface 254a of the engagement protrusion 252a. Therefore, when the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25, the first engagement portion 348a engages with the engagement protrusion 252a from the outside of the horizontal fitting groove 25.

[0043] The second engagement portion 348b protrudes indoors from the lower end of the side plate portion 341b. The vertical position of the second engagement portion 348b is the same as the vertical position of the first engagement portion 348a. The second engagement portion 348b extends indoors. The front end of the second engagement portion 348b is located closer to the indoor side than the indoor side surface of the side plate portion 341b. When the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25, the indoor-side tip of the second engagement portion 348b is located closer to the indoor side than the tip surface 254b of the engagement protrusion 252b. Therefore, when the retrofit screen door attachment 34 is fitted into the horizontal fitting groove 25, the second engagement portion 348b engages with the engagement protrusion 252b from the outside of the horizontal fitting groove 25.

[0044] The cross-sectional shape of the retrofit screen door attachment 34 perpendicular to the left-right direction is the same dimensions as the cross-sectional shape of the screen door attachment 33 perpendicular to the up-down direction shown in Figure 4. Because the cross-sectional shape of the retrofit screen door attachment 34 perpendicular to the left-right direction is the same dimensions as the cross-sectional shape of the screen door attachment 33 perpendicular to the up-down direction, management work is reduced, which contributes to cost reduction.

[0045] 5, the horizontal tape portion 323 sewn to the upper edge of the mesh portion 31 has a temporary fastening portion 35 that temporarily fastens the mesh portion 31 to the horizontal fitting groove 25 before fitting the retrofit screen attachment 34 into the horizontal fitting groove 25. The horizontal tape portion sewn to the lower edge of the mesh portion 31 has the same configuration as the horizontal tape portion 323, so the following will describe the temporary fastening portion 35 provided on the horizontal tape portion 323. The temporary fastening portion 35 corresponds to a temporary fastening member.

[0046] The temporary fastening portion 35 has a band-like shape with the left-right direction as the longitudinal direction, and its length in the left-right direction is approximately the same as that of the horizontal fitting groove 25. The temporary fastening portion 35 is composed of a tape half of a fastener, similar to the tape portion 32. The temporary fastening portion 35 has a fixed portion 352 attached to the horizontal tape portion 323 at one end 351 in the short side direction, a free end 354 engaged with the horizontal fitting groove 25 at the other end 353 in the short side direction, and a sewn portion 356 at a boundary 355 between the fixed portion 352 and the free end 354, where the horizontal tape portion 323 and the temporary fastening portion 35 are sewn together.

[0047] The fixing portion 352 is formed by adhering the end portion 351 and the mesh portion 31 facing the end portion 351 with double-sided tape 357 in the range up to the boundary 355. The mesh portion 31 adhered to the fixing portion 352 follows the deformation of the temporary fastening portion 35, with the point facing the boundary 355 as the boundary.

[0048] The free end 354 has a protruding hook portion 358 formed thereon that protrudes from the free end 354 toward the mesh portion 31 in a direction facing the mesh portion 31. The hook portion 358 is made up of a tape half of the fastener, similar to the temporary fastening portion 35.

[0049] The stitching portion 356 is formed by sewing the fixing portion 352 and the mesh portion 31 together in the longitudinal direction of the temporary fastening portion 35 at the boundary 355. The longitudinal length of the fixing portion 352 is formed to be greater than the length of the engaging protrusion 252a in the projection direction (left and right direction in FIG. 5) on the inside side of the horizontal fitting groove 25. When the screen door 3 is pushed upward so as to rotate in the counterclockwise direction of arrow T1 (see FIG. 7) around the opposing surface 354a of the free end portion 354 that faces the mesh portion 31, the mesh portion 31 hangs straight down from the stitching portion 356.

[0050] The method of attaching the screen door 3 to the frame body 2 will be described with reference to Figures 1 and 2 and Figures 4 to 9. Before attaching the screen door 3 to the frame body 2, as shown in Figure 1, the screen door attachments 33, 33 are engaged with and attached to the mesh part 31, and the add-on screen door attachments 34, 34 are separate from the mesh part 31.

[0051] From this state, first, the screen door attachments 33, 33 are attached to the vertical fitting grooves 26, 26 of the vertical frames 23, 24. Since the method of attaching the screen door attachments 33, 33 to the vertical frames 23, 24 is the same, the method of attaching them to the vertical frame 23 will be explained below.

[0052] As shown in FIG. 2, the screen door attachment 33 that fits into the vertical frame 23 is tilted relative to the frame 2 to store the screen door 3 inside the frame 2. As shown in FIGS. 4 and 6, the screen door attachment 33 is fitted into the vertical fitting groove 26 of the vertical frame 23 with the side panel 331a, which has the push-in portion 334, positioned on the indoor side. While FIGS. 4 and 6 only show the vertical frame 23 side, the same applies to the vertical frame 24. When fitting the screen door attachment 33 into the vertical fitting groove 26, the screen door attachment 33 is inserted in the direction of arrow T2 with the push-in portion 334 tilted toward the outdoor side, and the outdoor-side protrusion 337b engages with the engaging protrusion 262b from the inside of the vertical fitting groove 26. The protrusion 337a contacts the tip surface 264a of the engaging protrusion 262a. In this state, push-in portion 334 is pushed toward vertical fitting groove 26, and screen door attachment 33 is rotated clockwise in the direction of arrow T3 around the point of contact between protrusion 337b and engaging protrusion 262b. Protrusion 337a of screen door attachment 33 elastically climbs over engaging protrusion 262a. Protrusion 337a and engaging protrusion 262a, and protrusions 337b and 262b, engage inside vertical fitting groove 26, completing the installation of screen door attachment 33 into vertical fitting groove 26 as shown in FIG. 6.

[0053] The screen door attachments 33, 33 that fit into the vertical frames 23, 24 are combined vertically with the add-on screen door attachments 34, 34 that fit into the upper frame 21 and lower frame 22, respectively. This prevents the add-on screen door attachments 34, 34 from becoming difficult to fit into the horizontal fitting grooves 25, 25 of the upper frame 21 and lower frame 22. In other words, by attaching the screen door attachments 33, 33 to the mesh part 31 in advance, it is possible to prevent the attachment position of the add-on screen door attachments 34, 34 from shifting.

[0054] When the push-in portion 334 arranged on the indoor side is pushed in, the momentum released from the resistance caused when the protrusion 337a elastically overcomes the engaging protrusion 262a may cause the bottom plate portion 332 to reach the bottom surface 265 of the frame body 2, resulting in deformation, etc. A first engaging portion 338a is provided at the base of the push-in portion 334, which can prevent the bottom plate portion 332 from reaching the bottom surface 265 of the frame body 2 when the push-in portion 334 engages with the engaging protrusion 262a from the outside of the vertical fitting groove 26.

[0055] When the screen door 3 is subjected to an external force such as wind pressure from the outdoors, a force is applied to the screen door attachment 33 on the vertical frame 23 side, which rotates the pushing portion 334 side in a direction that moves it toward the indoors within the vertical fitting groove 26. Even in this case, when the first engagement portion 338a engages with the engagement protrusion 262a from the outside of the vertical fitting groove 26, the rotation of the pushing portion 334 side can be prevented. The outdoor-side protrusion 337b immediately moves over the outdoor-side engagement protrusion 262b of the vertical fitting groove 26 due to an external force such as wind pressure, preventing the screen door attachment 33 from unintentionally coming off the vertical fitting groove 26.

[0056] At this stage, the screen part 31 does not have the add-on screen attachment 34 attached, so the screen attachment 33 can be easily and stably attached to the vertical fitting groove 26. The screen attachment 33 fits firmly into the vertical fitting groove 26, which prevents the screen attachment 33 from floating up and becoming unintentionally detached, or the screen 3 from becoming loose.

[0057] After the screen door attachments 33, 33 are attached to the vertical fitting grooves 26, 26, respectively, the add-on screen door attachments 34, 34 are attached to the horizontal fitting grooves 25, 25 of the upper frame 21 and the lower frame 22. The method for attaching the add-on screen door attachments 34, 34 to the upper frame 21 and the lower frame 22 is the same, so the method for attaching them to the upper frame 21 will be explained below. Because the screen door attachments 33, 33 are attached to the vertical frames 23, 24 of the screen door 3, the work of attaching the add-on screen door attachment 34 can be carried out without the need for support by the worker's hands, etc.

[0058] The screen door attachments 33, 33 that fit into the vertical frames 23, 24 are combined vertically with the add-on screen door attachments 34, 34 that fit into the upper frame 21 and lower frame 22, respectively, so the horizontal fitting groove 25 into which the add-on screen door attachment 34 fits is open and exposed in the vertical direction to the inside of the fixture 1 without interfering with the vertical frames 23, 24. As a result, when the add-on screen door attachment 34 is fitted into the horizontal fitting groove 25, it can be easily installed without interfering with the vertical frames 23, 24.

[0059] When the retrofit screen attachment 34 is fitted into the horizontal fitting groove 25, as shown in FIG. 5, the temporary fastening portion 35 is positioned in the horizontal fitting groove 25 with the fixing portion 352 facing upward and close to the engaging protrusion 252a. As shown in FIG. 7, the worker places a finger F on the opposing surface 354a of the free end 354 of the temporary fastening portion 35 and pushes the free end 354 upward so as to rotate counterclockwise around the sewn portion 356 in the direction of arrow T1. The tip 352a of the fixing portion 352 of the temporary fastening portion 35 is close to the outdoor-side corner 255a of the bottom surface 255. Because the mesh portion 31 hangs downward from the sewn portion 356, the temporary fastening portion 35 can be pushed in without getting caught on the engaging protrusions 252a, 252b. When the free end 354 is further pressed in so as to rotate in the direction of arrow T1, the free end 354 abuts against the engaging protrusion 252b, and the temporary fastening portion 35 elastically deforms around the tip 352a of the fixing portion 352 as a fulcrum, thereby elastically climbing over the engaging protrusion 252b. As shown in FIG. 8 , when the tip 352a of the fixing portion 352 and the hook portion 358 engage with the engaging protrusions 252a, 252b from the inside of the lateral fitting groove 25, the temporary fastening portion 35 is held in the lateral fitting groove 25 in a convexly elastically deformed state. The engagement between the engaging protrusion 252b and the hook portion 358 prevents the temporary fastening portion 35 from easily falling out of the lateral fitting groove 25.

[0060] The temporary fastening portion 35 is pushed into the horizontal fitting groove 25 in a direction that spreads it outward both to the indoor side and to the outdoor side, and the pushing finger F is slid several times left and right across the horizontal fitting groove 25. The task of pushing the temporary fastening portion 35 left and right across the screen door 3 with the finger F is a simple action, so the force that pushes in the temporary fastening portion 35 is easy to apply, and if the opening 253 of the horizontal fitting groove 25 is formed large enough for the worker's finger F to enter, the temporary fastening portion 35 can be easily attached without having to pinch it with the finger F.

[0061] As shown in FIG. 9, the retrofit screen door attachment 34 is attached with the temporary fastening portion 35 held within the horizontal fitting groove 25. Similar to the screen door attachment 33, the retrofit screen door attachment 34 is first fitted into the horizontal fitting groove 25 with the push-in portion 344 tilted toward the exterior, and the outdoor-side protrusion 347a is engaged with the engaging protrusion 252a from the inside of the horizontal fitting groove 25. The mesh portion 31 hanging downward from the horizontal fitting groove 25 is positioned between the engaging protrusion 252a and the retrofit screen door attachment 34. The protrusion 347b comes into contact with the tip surface 254b of the engaging protrusion 252b. The push-in portion 344 is then further pushed toward the horizontal fitting groove 25 so that the retrofit screen door attachment 34 rotates counterclockwise around the point of contact between the protrusion 347a and the engaging protrusion 252a. The protrusion 347b of the retrofit screen door attachment 34 elastically overcomes the engaging protrusion 252b and engages with it from the inside of the horizontal fitting groove 25, completing the attachment of the retrofit screen door attachment 34 to the horizontal fitting groove 25, as shown in Figure 9. At this time, the temporary fastening portion 35 is held in the horizontal fitting groove 25 in a convex, elastically deformed state, so the mesh portion 31 does not sag downward. Therefore, the retrofit screen door attachment 34 can be easily attached regardless of the flexibility of the mesh portion 31.

[0062] When the push-in portion 344 arranged on the indoor side is pushed in, the momentum released from the resistance caused when the protrusion 347b elastically overcomes the engaging protrusion 252b may cause the bottom plate portion 342 to reach the bottom surface 255 of the frame body 2, resulting in deformation, etc. A second engaging portion 348b is provided at the base of the push-in portion 344, and when the push-in portion 344 engages with the engaging protrusion 252b from outside the lateral fitting groove 25, it is possible to prevent the bottom plate portion 342 from reaching the bottom surface 255 of the frame body 2.

[0063] When the screen door 3 is subjected to an external force such as wind pressure from the outdoors, a force is applied to the retrofit screen door attachment 34 in a direction that causes the push-in portion 344 to move indoors within the horizontal fitting groove 25. Even in this case, rotation of the push-in portion 344 can be prevented when the second engagement portion 348b engages with the engagement protrusion 252b from the outside of the horizontal fitting groove 25. This prevents the outdoor-side protrusion 347a from immediately climbing over the outdoor-side engagement protrusion 252a of the horizontal fitting groove 25 due to an external force such as wind pressure, thereby preventing the retrofit screen door attachment 34 from unintentionally coming off the horizontal fitting groove 25.

[0064] As explained above, the screen door attachments 33, 33 and the add-on screen door attachments 34, 34 are attached to the frame body 2, and the screen door 3 is attached to the frame body 2. By attaching the temporary fastening parts 35 to the horizontal fitting grooves 25 of the screen door 3 before fitting the add-on screen door attachment 34 into the horizontal fitting grooves 25, the add-on screen door attachment 34 can be easily attached without affecting the tension of the mesh part 31 due to sagging of the mesh part 31 when the add-on screen door attachment 34 is attached.

[0065] The preferred embodiments of the present disclosure have been described above with reference to the drawings. 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 can be appropriately changed or replaced based on design requirements, etc., without departing from the spirit and scope of the present disclosure.

[0066] For example, in the above embodiment, the tape portion 32 and the temporary fastening portion 35 are configured as half tapes of a fastener. However, the present invention is not limited to this configuration, and the tape portion 32 and the temporary fastening portion 35 may be configured as an elastic plate member such as a thin plastic material.

[0067] In the above embodiment, the orientation of the screen door 3 is defined as either the indoor or outdoor side. However, this is not limiting, and each component of the screen door 3, such as the add-on screen door attachment 34, may be provided with a mark or the like clearly indicating whether it is the indoor or outdoor side.

[0068] In the above embodiment, the temporary fastening portion 35 is pushed upward with the finger F, and the temporary fastening portion 35 is stored in the horizontal fitting groove 25. However, the present invention is not limited to this configuration, and the temporary fastening portion 35 may be pushed in with a rod-shaped material or the like.

[0069] In the above embodiment, a configuration has been exemplified in which, before the screen door 3 is attached to the frame 2, the screen door attachment 33 is engaged with and attached to the mesh part 31, and the add-on screen door attachment 34 is separate from the mesh part 31. However, this configuration is not limited to this, and a configuration may also be used in which, before the screen door 3 is attached to the frame 2, the attachments to be attached to the upper and lower edges of the mesh part 31 are engaged with and attached in advance, and the attachments to be attached to the left and right edges of the mesh part 31 are separate from the mesh part 31. In this case, it is preferable that the attachments to be attached to the upper and lower edges of the mesh part 31 override the attachments to be attached to the left and right edges of the mesh part 31, respectively, so that the screen door 3 is assembled in a so-called horizontally passing configuration.
