Description

[Technical Field]

[0001] The present disclosure relates to screen doors. [Background technology]

[0002] When opening a sliding window in a house or similar and using a screen to prevent insects from getting in, the inner screen is moved to the side where it overlaps with the outer screen to open the opening, and the screen is placed in the open area. By doing this, the vertical stile of the screen overlaps with the outdoor side of the vertical stile of the outer screen, reducing the gap between the screen and the screen, preventing insects from getting in through the gap between them.

[0003] Depending on the residential environment, such as the relative position of neighboring houses, the arrangement of indoor furniture, and security, it may be difficult to arrange screen doors as described above. Patent Document 1 discloses a fixture in which multiple sliding screen doors cover the entire opening. Fixtures that cover the entire opening with a single screen door are also known. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-8600 A Summary of the Invention [Problem to be solved by the invention]

[0005] When installing multiple sliding screen doors, multiple screen door rails are required, which makes the frame shape of the fixture more complex and larger. This can lead to a decrease in workability and design. When covering the entire opening with a single screen door, simply enlarging a conventional screen door makes it impossible to fit both ends of the screen door into the vertical frame, requiring special tools and installation methods, which reduces workability.

[0006] The object of the present disclosure is to provide a screen door that can cover the entire opening with one sheet and can be easily attached to a frame. [Means for solving the problem]

[0007] In order to achieve the above-mentioned objectives, the screen door of the present disclosure comprises a frame supported on the frame of a fixture, and a mesh material attached to the frame, the frame having horizontal frames at the upper and lower ends and vertical frames at both ends in the width direction, the vertical frames having a mesh material mounting portion to which the mesh material is attached, an outdoor rib that protrudes outward in the width direction from the mesh material mounting portion, and a locking portion that is switchable between a locked position located on the indoor side of the outdoor rib and protruding outward in the width direction from the mesh material mounting portion, and an unlocked position located inward in the width direction from the mesh material mounting portion.

The mohair 315 and mohairs 325 and 361 described below correspond to gap filling members in the claims.

[0014] The bottom frame 32 has a mesh mounting portion 321, an outdoor rib 322, and an indoor rib 323. The mesh 4 is attached to the mesh mounting portion 321. The outdoor rib 322 extends downward from the outdoor end of the lower end of the mesh mounting portion 321. The indoor rib 323 extends downward from the indoor end of the lower end of the mesh mounting portion 321. The outdoor rib 322 and the indoor rib 323 are arranged parallel to each other and spaced apart in the indoor-outdoor direction. The bottom frame 32 has a recess 324 that opens downward and is surrounded by the upper end surface of the mesh mounting portion 321, the outdoor rib 322, and the indoor rib 323. The screen rail 212a of the bottom frame 212 is inserted into the recess 324. A mohair 325 that protrudes indoors is attached to the tip of the outdoor rib 322. The mohair 325 is provided over the entire length of the lower frame 32, i.e., the entire width of the lower frame 32. The mohair 325 is a member that fills the gap between the lower frame 32 and the lower frame 212.

[0015] As shown in Figures 6 and 7, the first stile 33 has a net mounting portion 35 and an outdoor rib 36. The net 4 is attached to the net mounting portion 35. The outdoor rib 36 extends outward in the width direction from one widthwise side of the net mounting portion 35, i.e., the outdoor end of the outer widthwise end. The first stile 33 does not have an indoor rib corresponding to the indoor ribs 313, 323 of the upper and lower stiles 31 and 32. The outdoor rib 36 is positioned outside the screen rail 213a of the first vertical frame 213. A mohair 361 protruding indoors is attached to the tip of the outdoor rib 36. The mohair 361 is provided along the entire length of the first stile 33, i.e., the entire vertical direction. The mohair 361 is a member that seals the gap between the first stile 33 and the first vertical frame 213. Similarly, the mohair 361 provided on the second vertical frame 34 is provided over the entire length of the second vertical frame 34, i.e., over the entire vertical direction. The mohair 361 provided on the second vertical frame 34 is a member that fills the gap between the second vertical frame 34 and the second vertical frame 214.

[0016] The mesh material mounting portion 35 is formed in a rectangular cylindrical shape. The mesh material mounting portion 35 has an outdoor plate portion 351, an indoor plate portion 352, an inner plate portion 353, and an outer plate portion 354. The outdoor plate portion 351 is provided along the outdoor surface of the mesh material mounting portion 35. The indoor plate portion 352 is provided along the indoor surface of the mesh material mounting portion 35. The inner plate portion 353 is provided along the inner surface in the width direction of the mesh material mounting portion 35. The outer plate portion 354 is provided along the outer surface in the width direction of the mesh material mounting portion 35. The outdoor side rib 36 is provided continuously on the outer side in the width direction of the outdoor plate portion 351.

[0017] As shown in FIG. 8, an indoor panel cutout 352a is formed in the indoor panel 352. As shown in FIG. 5, two indoor panel cutouts 352a are formed at a vertically spaced interval in the vertically central portion of the indoor panel 352. As shown in FIG. 8, an outer panel cutout 354a is formed in the outer panel 354. Two outer panel cutouts 354a are formed at a vertically spaced interval in the vertically central portion of the outer panel 354. The indoor panel cutout 352a and the outer panel cutout 354a are formed contiguously at the same height. As shown in FIG. 8, the indoor panel cutout 352a and the outer panel cutout 354a, which are formed contiguously at the same height, are collectively referred to as cutout 355. The cutout 355 of the mesh mounting portion 35 opens to the indoor side and to the outside in the width direction.

[0018] As shown in Figures 4 to 7, a locking portion 5 is provided on the first vertical stile 33. As shown in Figures 4 and 5, two locking portions 5 are provided on the first vertical stile 33 with a gap between them in the vertical direction. The locking portion 5 is provided at a position where the notch 355 is formed in the mesh material mounting portion 35 of the first vertical stile 33. As shown in Figures 6 to 9, the locking portion 5 has an mounting portion 51, a locking piece 52, and an operating portion 53. The mounting portion 51 is attached to the mesh material mounting portion 35. The locking piece 52 is rotatably attached to the mounting portion 51. The operating portion 53 is connected to the mounting portion 51. The user operates the operating portion 53 to rotate the locking piece 52.

[0019] As shown in Figures 7 to 9, the mounting portion 51 is fitted into the cutout 355 of the net mounting portion 35. The mounting portion 51 has a front plate 511, an inner plate 512, an upper plate 513, a lower plate 514, an upper rear plate 515, a lower rear plate 516, an upper outer plate 517, and a lower outer plate 518. The front plate 511 is located on the indoor side and is exposed to the indoor side from the indoor plate cutout 352a of the net mounting portion 35. The front plate 511 is located on the indoor side of the outdoor plate 351 of the net mounting portion 35 with a gap therebetween. A lock piece 52 is located in this gap. A hole 511a that penetrates from indoor to outdoor is formed in the vertical middle of the mounting portion 51. An operating portion 53 is located in the hole 511a. A front panel protrusion 511b that protrudes toward the outside is formed at the middle portion in the up-down direction of the outer edge in the width direction of the front panel 511.

[0020] The inner plate portion 512 extends from the other widthwise side of the front plate portion 511, i.e., from the inner edge portion in the widthwise direction, toward the outdoor side. A hole portion 512a penetrating in the widthwise direction is formed in the vertical middle portion of the inner plate portion 512. The front plate portion 511 extends from the upper edge portion of the front plate portion 511 toward the indoor side. An upper protrusion portion 513a protruding downward is formed in the widthwise middle portion of the front plate portion 511. The upper plate portion 513 extends from the upper edge portion of the front plate portion 511 toward the indoor side. An upper protrusion portion 513a protruding downward is formed in the widthwise middle portion of the upper plate portion 513. The lower plate portion 514 extends from the lower edge portion of the front plate portion 511 toward the indoor side. A lower protrusion portion 514a protruding upward is formed in the widthwise middle portion of the lower plate portion 514.

[0021] The upper rear plate portion 515 extends upward from the outdoor-side edge of the upper plate portion 513. The lower rear plate portion 516 extends downward from the outdoor-side edge of the lower plate portion 514. The upper outer plate portion 517 extends indoors from the outer edge of the upper rear plate portion 515 in the width direction. The lower edge of the upper outer plate portion 517 is connected to the outer edge of the upper plate portion 513 in the width direction. The lower outer plate portion 518 extends indoors from the outer edge of the lower rear plate portion 516 in the width direction. The upper edge of the lower outer plate portion 518 is connected to the outer edge of the lower plate portion 514 in the width direction. The rear side of the front plate portion 511 of the mounting portion 51 opens outward in the width direction.

[0022] As shown in FIG. 8 , the locking piece 52 has an elongated shape. When viewed from the indoor / outdoor direction, the locking piece 52 has a substantially oval shape. The locking piece 52 is molded from an elastically deformable material such as resin. One longitudinal end of the locking piece 52 is referred to as a first end 52a, and the other longitudinal end is referred to as a second end 52b. The first end 52a and the second end 52b of the locking piece 52 are formed in a convex shape that protrudes in the longitudinal direction. The locking piece 52 rotates around a rotation axis 521 extending in the indoor / outdoor direction. The rotation axis 521 is located on one side of the locking piece 52 in the longitudinal direction, not in the center. The locking piece 52 is positioned behind the front plate 511 of the mounting portion 51 so that the rotation axis 521 is located in the center of the hole 511a of the front plate 511 of the mounting portion 51. The locking piece 52 can be switched by rotating about the rotation axis 521 between a locked position in which the second end 52b is positioned outward in the width direction relative to the first end 52a as shown in Figures 6 and 7, and an unlocked position in which the second end 52b is positioned above the first end 52a as shown in Figures 10 and 11. When the locking piece 52 in the unlocked position rotates about the rotation axis 521 so that the second end 52b faces downward and outward in the width direction, it assumes the locked position.

[0023] As described above, the operating unit 53 is disposed in the hole 511a of the front panel 511. The operating unit 53 is connected to the locking piece 52. A user can rotate the operating unit 53 from the indoor side of the first vertical frame 33 to rotate the locking piece 52. The operating unit 53 has a slit 531 formed therein into which, for example, the edge of a coin can be inserted. A user can insert the edge of a coin into this slit 531 and rotate the coin to rotate the locking piece 52.

[0024] The second end 52b of the locking piece 52 in the locked position protrudes outward in the width direction beyond the front plate 511 of the mounting part 51, and protrudes outward in the width direction from the outer plate cutout 354a of the net mounting part 35. The first end 52a of the locking piece 52 is inserted into the hole 512a of the inner plate 512. The entire locking piece 52 in the unlocked position is positioned on the outdoor side of the front plate 511 of the mounting part 51. The locking piece 52 in the unlocked position is positioned inside the net mounting part 35. The first end 52a of the locking piece 52 is positioned above and spaced from the lower protrusion 514a of the lower plate 514. The second end 52b of the locking piece 52 is positioned below the upper protrusion 513a of the upper plate 513 and in contact with the upper protrusion 513a.

[0025] A first elongated hole 522 penetrating in the indoor / outdoor direction is formed near the first end 52a of the locking piece 52. A second elongated hole 523 penetrating in the indoor / outdoor direction is formed near the second end 52b of the locking piece 52. The first elongated hole 522 and the second elongated hole 523 extend in a direction intersecting the longitudinal direction of the locking piece 52. When the locking piece 52 changes from the unlocked position to the locked position, the first end 52a of the locking piece 52 rotating around the rotation axis 521 comes into contact with the inner plate portion 512, causing the locking piece 52 to elastically deform and crush the first elongated hole 522. When the locking piece 52 changes to the locked position, the first end 52a of the locking piece 52 is inserted into the hole 512a of the inner plate portion 512, and the elastic deformation is restored. This allows the user to feel a clicking sensation when the locking piece 52 changes to the locked position. When the locking piece 52 assumes the unlocked position and the second end 52b of the locking piece 52 comes into contact with the upper protrusion 513a of the upper plate portion 513, the locking piece 52 elastically deforms and the second elongated hole portion 523 collapses. The restoring force of the elastic deformation causes the second end 52b to press upward against the upper protrusion 513a of the upper plate portion 513. This allows the user to feel a click when the locking piece 52 assumes the unlocked position.

[0026] A guide groove 524 is formed on the indoor-facing surface of the locking piece 52. A front plate protrusion 511b that protrudes to the outdoor side from the front plate 511 of the mounting part 51 is inserted into the guide groove 524. When the locking piece 52 rotates, the rotation of the locking piece 52 is guided by the front plate protrusion 511b being inserted into the guide groove 524. When the locking piece 52 is in the locked position, the front plate protrusion 511b comes into contact with an upper end surface 524a of the guide groove 524 from above, and downward rotation is restricted.

[0027] The second vertical frame 34 has a shape symmetrical in the width direction to the first vertical frame 33. The second vertical frame 34 is also provided with a locking portion 5 similar to the locking portion 5 of the first vertical frame 33.

[0028] We will now explain how to attach the screen door 1 to the frame body 21. The locking pieces 52 of the locking portions 5 of the first vertical frame 33 and the second vertical frame 34 are placed in the unlocked position. The screen door 1 is moved up and down in a knock-on manner, and the screen door rail of the upper frame is inserted into the recess in the upper frame, and the screen door rail of the lower frame is inserted into the recess in the lower frame. The outdoor side rib 36 of the first vertical frame 33 is positioned on the outdoor side of the screen door rail 213a of the first vertical frame 213. The outdoor side rib 36 of the second vertical frame 34 is positioned on the outdoor side of the screen door rail 214a of the second vertical frame 214.

[0029] The locking piece 52 of the locking portion 5 of the first stile 33 and the locking piece 52 of the locking portion 5 of the second stile 34 are rotated around the rotation axis 521 to assume a locked position. The first end 52a of the locking piece 52 of the first stile 33 is positioned on the indoor side of the screen door rail 213a of the first vertical frame 213. The first end 52a of the locking piece 52 of the second stile 34 is positioned on the indoor side of the screen door rail 214a of the second vertical frame 214. The outdoor-side rib 36 of the first stile 33 and the locking piece 52 sandwich the screen door rail 213a of the first vertical frame 213 from the indoor / outdoor direction. The outdoor-side rib 36 of the second stile 34 and the locking piece 52 sandwich the screen door rail 214a of the second vertical frame 214 from the indoor / outdoor direction. The locking pieces 52 are in contact with the screen door rails 213a and 214a from the indoor side.

[0030] When the screen door 1 is attached to the frame body 21 and the locking piece 52 of the locking portion 5 is in the locked position, the outdoor-side rib 36 of the first vertical frame 33 and the second vertical frame 34 and the locking piece 52 sandwich the screen door rail 213a of the first vertical frame 213 and the screen door rail 214a of the second vertical frame 214 from the indoor / outdoor direction. Therefore, even if the screen door 1 attached to the frame body 21 is about to lift up and the bottom frame 32 is about to come off the screen door rail 212a of the bottom frame 212, the screen door 1 is prevented from moving in the indoor / outdoor direction, preventing the screen door 1 from coming off the frame body 21. When attached to the frame body 21 and in the locked position, the locking piece 52 is in contact with the indoor-side surfaces of the screen door rails 213a and 214a. This prevents the screen door 1 from rattling or being lifted up by wind.

[0031] The locking piece 52 can be switched between a locked position and an unlocked position. Therefore, by setting the locking piece 52 in the unlocked position, the screen door 1 can be fitted into the frame body 21 in a snap-on manner. Because the locking piece 52 can be set to the locked position after the screen door 1 has been fitted into the frame body 21, the locking piece 52 does not interfere with the screen door rails 213a, 214a when fitting the screen door 1 into the frame body 21. As a result, the screen door 1 can be easily attached to the frame body 21.

[0032] The locking portion 5 can easily switch the locking piece 52 between the unlocked position and the locked position by operating the operating portion 53 from inside the room.

[0033] Mohair 315, 325, 361 is provided along the entire length of each of the upper frame 31, lower frame 32, first vertical frame 33, and second vertical frame 34 of the screen door 1. As a result, the mohair 315, 325, 361 can seal the gap between the frame 3 of the screen door 1 and the frame body 21. This improves the insect-proofing properties of the screen door 1, which covers the entire opening 12 with a single sheet.

[0034] Because the screen door 1 shown in this embodiment covers the entire opening 12, the opening can be covered by the screen door 1 not only when the outer and inner screens 22 and 23 are all moved to one side in the width direction to open it, but also when the outer and inner screens 22 and 23 are moved toward each other so that they are completely overlapping, or when they are opened with only a partial overlap as shown in Figures 1 and 4. Because the screen door 1 shown in this embodiment covers the entire opening 12, insects and other insects cannot get in between the outer and inner screens 22 and 23 and the screen door 1, regardless of their positions. As a result, the fitting 2 shown in this embodiment can efficiently ventilate from the outside by positioning the outer and inner screens 22 and 23 as desired. If the screen door 1 shown in this embodiment is used in a window installed in a bathroom or toilet, for example, it can prevent insects from entering the room when one or both sides of the width of the window are slightly opened for ventilation to block views from outside.

[0035] The present disclosure is not limited to the above-described embodiment and can be modified as appropriate. For example, in the above-described embodiment, two locking units 5 are provided on each of the first and second vertical frames 33 and 34, spaced apart in the vertical direction, but the positions and number of locking units 5 provided on the first and second vertical frames 33 and 34 may be set as appropriate. The locking unit 5 may have a configuration other than the above as long as it can be switched between a locked position in which it is positioned on the indoor side of the screen door rails 213a, 214a of the first and second vertical frames 213 and 214, and an unlocked position in which it is not positioned on the indoor side of the screen door rails 213a, 214a.

[0036] Mohair 315, 325, 361 is provided along the entire length of each of the upper stile 31, lower stile 32, first vertical stile 33, and second vertical stile 34 of the screen door 1. The position at which the mohair is provided relative to the stile 3 of the screen door 1 may be set as appropriate. Instead of the mohair 315, 325, 361, the stile 3 of the screen door 1 may be provided with packing, fin-shaped rubber material, sponge, etc. as a gap-closing member that closes the gap between the stile 3 and the frame body 21. The screen door 1 does not necessarily have to be provided with a gap-closing member that closes the gap between the stile 3 and the frame body 21.
