[0010] The building components of the embodiment of the present invention will now be described with reference to the drawings. Figure 1 is a vertical cross-sectional view of a vertical sliding window 1, which is a building component of the embodiment, and Figure 2 is a horizontal cross-sectional view of the vertical sliding window 1. The vertical sliding window 1 is installed in an opening in a building and comprises a window frame 2, a sash 3 placed inside the window frame 2, a connecting part 4 that connects the window frame 2 to the sash 3 so that it can be opened and closed in a vertical sliding manner, a screen door frame 5 attached to the inner circumference of the window frame 2, and a screen door 6 that is detachably attached to the screen door frame 5. The screen door frame 5 is an example of a screen frame, and the screen door 6 is an example of a screen body. The horizontal direction along the wall surface of the building where the vertical sliding window 1 is installed is defined as the X-axis direction, the vertical direction along the wall surface is defined as the Y-axis direction, and the direction perpendicular to the wall surface (indoor / outdoor) is defined as the Z-axis direction. As shown in Figure 2, in the X-axis direction, the direction to the left when viewing the vertical sliding window 1 from the indoor side is defined as the X1 direction, and the direction to the right is defined as the X2 direction. In the Y-axis direction, the upward direction is defined as the Y1 direction, and the downward direction is defined as the Y2 direction. In the Z-axis direction, the direction from the outdoor side towards the indoor side is defined as the Z1 direction, and the direction towards the outdoor side is defined as the Z2 direction.

[0011] The window frame 2 is composed of a top frame 21, a bottom frame 22, and left and right vertical frames 23, 24 that form a framework. The shoji 3 is composed of a top frame 31, a bottom frame 32, left and right vertical frames 33, 34, and a facing material 35 such as a glass panel. The connecting component 4 is respectively attached between the top frame 21 and the top frame 31, and between the bottom frame 22 and the bottom frame 32, and includes upper and lower stays 41, 42 that support the shoji 3 so that it can be opened and closed on the outdoor side with respect to the window frame 2, an operator handle 43 provided on the bottom frame 22, and an arm 44 that connects the bottom frame 32 and the operator handle 43. Note that the operator handle 43 is only shown in FIG. 1 and is omitted in other figures. The vertical sliding window 1 can open and close the shoji 3 by operating the operator handle 43. Also, since the shoji 3 can be opened and closed by the operator handle 43, there is no need to open and close the screen door 6 arranged on the indoor side of the shoji 3 when the shoji 3 is opened and closed. Therefore, the screen door 6 of this embodiment is a fixed screen door that is only removed from the screen door frame 5 during cleaning or when damaged.

[0012] [Screen door frame] In the window frame 2, a screen door frame 5 is attached on the indoor side of the shoji 3. The screen door frame 5 is provided so as to cover the inner peripheral surface that is exposed on the indoor side when the shoji 3 is closed in the window frame 2. The screen door frame 5 includes an upper frame 51 and a lower frame 52 that are horizontal frames, and left and right vertical frames 53, 54. The upper frame 51, the lower frame 52, the vertical frames 53, 54 are composed of, for example, resin profiles formed by extrusion molding. The upper frame 51 and the lower frame 52 are respectively attached to the upper frame 21 and the lower frame 22 at two hook portions on the indoor and outdoor sides, and are further screwed to an interior finish material 8 such as a picture frame. Similarly, the vertical frames 53, 54 are respectively attached to the vertical frames 23, 24 at two hook portions on the indoor and outdoor sides and are screwed to the interior finish material 8. Then, by framing the upper frame 21, the lower frame 22, the vertical frames 23, 24 to which the upper frame 51, the lower frame 52, the vertical frames 53, 54 are attached, the ends of the upper frame 51 and the lower frame 52 and the vertical frames 53, 54 are connected to each other to form the screen door frame 5.

[0013] A screen door 6 is installed in the opening part inside the screen door frame 5. For this reason, the upper frame 51, the lower frame 52, and the vertical frames 53 and 54 of the screen door frame 5 have upper groove parts 510, lower groove parts 520, vertical groove parts 530, and 540 which are groove parts where the screen door 6 is arranged.

[0014] As shown in FIG. 3, the upper frame 51 has an inner peripheral surface part 511 located on the inner circumference of the screen door frame 5, a groove partitioning part 512 extending upward (Y1 direction) from the inner peripheral surface part 511 and further extending outward (Z2 direction), and an outdoor piece part 513 extending downward (Y2 direction) from the outdoor end of the groove partitioning part 512. And the upper groove part 510 opening downward is partitioned and formed by the groove partitioning part 512 and the outdoor piece part 513. A concave part 515 is formed on the surface of the outdoor piece part 513 of the groove partitioning part 512 facing it, and a locking part 514 protruding outward is formed at the lower end of the groove partitioning part 512.

[0015] As shown in FIG. 4, the lower frame 52 has an inner peripheral surface part 521 located on the inner circumference of the screen door frame 5, a groove partitioning part 522 protruding upward (Y1 direction) from the inner peripheral surface part 521, and an outdoor piece part 523 extending upward from the inner peripheral surface part 521 on the outdoor side of the groove partitioning part 522. And the lower groove part 520 opening upward is partitioned and formed by the groove partitioning part 522 and the outdoor piece part 523. A locking part 525 protruding inward (Z1 direction) is formed in the middle of the outdoor piece part 523 in the height direction. Also, a protruding part 526 protruding inward is formed at the upper end of the outdoor piece part 523. The height position of the upper end of the groove partitioning part 522 is set to a position lower than the lower surface of the outdoor piece part 523. The height dimension of this groove partitioning part 522 is set to be less than or equal to the dimension that allows the screen door 6 to move up and down in the upper groove part 510 as described later, and when the screen door 6 is lifted, the lower end of the screen door 6 can easily cross over the groove partitioning part 522.

[0016] As shown in Figure 5, the vertical frame 53 has an inner circumferential surface portion 531 located on the inner circumference of the screen door frame 5, and includes a groove compartment portion 532 extending from the inner circumferential surface portion 531 in the X1 direction and further extending outwards (in the Z2 direction), and an outdoor piece portion 533 extending in the X2 direction from the outdoor end of the groove compartment portion 532. The groove compartment portion 532 and the outdoor piece portion 533 then compartmentalize a vertical groove portion 530 that opens in the X2 direction. A recess 535 is formed on the surface of the groove compartment 532 facing the outdoor side portion 533, and a locking portion 534 is formed on the inner circumference end of the groove compartment 532, projecting toward the outdoor side.

[0017] As shown in Figure 6, the vertical frame 54 has an inner circumferential surface portion 541 located on the inner circumference of the screen door frame 5, and includes a groove compartment portion 542 extending in the X2 direction from the inner circumferential surface portion 541 and further extending outwards, and an outdoor piece portion 543 extending in the X1 direction from the outdoor end of the groove compartment portion 542. The groove compartment portion 542 and the outdoor piece portion 543 divide and form a vertical groove portion 540 that opens in the X1 direction. A recess 545 is formed on the surface of the groove compartment 542 facing the outdoor side portion 543, and a locking portion 544 is formed on the inner circumference end of the groove compartment 542, projecting toward the outdoor side.

[0018] [Screen door] Next, we will explain the screen door 6. Figure 7 is a perspective view showing the screen door 6. The screen door 6 has a rectangular frame 60 and a rectangular net 80 held by the frame 60. The net 80 is an example of a screen. The frame 60 comprises upper and lower horizontal members, upper member 61 and lower member 62, left and right vertical members 63 and 64, and corner members 70. The corner members 70 comprises an upper corner member 70A fixed to the upper member 61 and a lower corner member 70B fixed to the lower member 62. The upper member 61, lower member 62, and vertical members 63 and 64 are elastically deformable frame materials and are made of resin profiles or the like with the same cross-sectional shape. Specifically, as shown in Figure 3, the upper member 61 is formed in an L-shape in cross-section, comprising a plate-shaped mounting piece 611 that extends along the X-axis direction (left-right direction) and a guide piece 612 that protrudes outward from the upper end (outer circumference end) of the mounting piece 611. As shown in Figure 4, the lower member 62, like the upper member 61, is formed in an L-shape in cross-section and includes a plate-shaped mounting piece 621 and a guide piece 622 that protrudes outward from the lower end (outer circumference end) of the mounting piece 621. As shown in Figure 5, the vertical member 63, like the upper member 61 and the lower member 62, is formed in an L-shape in cross-section, comprising a plate-shaped mounting piece 631 and a guide piece 632 that protrudes outward from the X1 end (outer circumference end) of the mounting piece 631. As shown in Figure 6, the vertical member 64, like the vertical member 63, is formed in an L-shape in cross-section, comprising a plate-shaped mounting piece 641 and a guide piece 642 that protrudes outward from the X2 end (outer circumference end) of the mounting piece 641.

[0019] The exterior surface of each mounting piece 611, 621, 631, and 641 is the mounting surface to which the outer edge of the net 80 is fixed with the single-sided tape 85 described later, and the interior surface is the fixing surface to which it is fixed to the corner material 70. Furthermore, as shown in Figure 3, the extension dimension L1 of the guide piece 612 extending from the outdoor surface of the mounting piece 611 in the depth direction, i.e., the outdoor direction (Z2 direction), is greater than the thickness dimension L2 in the depth direction (Z2 direction) of the net 80 and single-sided tape 85 attached to the outdoor surface of the mounting piece 611. In other words, the thickness dimension L2 is the thickness dimension from the outdoor surface of the mounting piece 611 to the outdoor surface of the single-sided tape 85, and is equivalent to the sum of the thickness dimension of the net 80 and the thickness dimension of the single-sided tape 85. The dimensional difference L1-L2 between the outer surface of the guide piece 612 and the outer surface of the single-sided tape 85 is, for example, about 0.5 to 1.0 mm. That is, the dimension L3 = L1-L2 in the projection direction between the outer piece 513 and the single-sided tape 85 is about 0.5 to 1.0 mm, and by ensuring this gap dimension L3, it is prevented that the single-sided tape 85 will come into contact with the outer piece 513 and peel off when inserting the upper material 61 of the screen door 6 into the upper groove 510 or removing it from the upper groove 510. In the vertical members 63 and 64, the extension dimensions of the guide pieces 632 and 642 are made larger than the thickness dimensions of the net 80 and the single-sided tape 85, thereby securing a gap between the outdoor pieces 533 and 543 and the single-sided tape 85 and preventing the single-sided tape 85 from peeling off. In the lower member 62, the extension dimension of the guide piece 622 is greater than the thickness dimension of the net 80 and the single-sided tape 85. As shown in Figure 4, when the handle component 95 is in contact with the outdoor surface of the groove section 522, the guide piece 622 does not come into contact with the outdoor section 523, ensuring a gap between the locking portion 525 and the single-sided tape 85, thereby preventing the single-sided tape 85 from peeling off. The gap dimension between the locking portion 525 and the single-sided tape 85 is set to be less than or equal to the gap dimension between the guide piece 622 and the outdoor section 523, so that even when the lower member 62 moves to the outdoor side and the guide piece 622 comes into contact with the outdoor section 523, the locking portion 525 does not come into contact with the single-sided tape 85, or if it does, peeling does not occur. Furthermore, in the state shown in Figure 4, the position of the Z-axis direction of the indoor surface of the locking portion 525 is set to be on the indoor side (towards the Z1 direction) than the position of the Z-axis direction of the outdoor surface of the guide piece 622. This is configured so that if the lower member 62 moves upward unintentionally, the guide piece 622 will come into contact with the lower surface of the locking portion 525 and lock in place.

[0020] The corner members 70 (upper corner member 70A, lower corner member 70B) are connecting members that connect the upper and lower horizontal members, upper member 61 and lower member 62, and the left and right vertical members 63 and 64. As shown in Figures 7, 8, and 9, the corner member 70 has a horizontal member fixing part 71 to which the ends of the horizontal members, upper member 61 and lower member 62, are fixed, a vertical member fixing part 72 to which the ends of the vertical members 63 and 64 are fixed, and a connecting part 73 that connects the horizontal member fixing part 71 and the vertical member fixing part 72. The corner member 70 is made of an elastically deformable resin material and is manufactured by injection molding or the like. Figure 8(A) shows the exterior surface of the corner member 70, and Figure 8(B) shows the interior surface of the corner member 70.

[0021] The exterior surface of the horizontal member fixing section 71 includes a fixing surface 711 to which the upper member 61 or lower member 62 is fixed with double-sided tape or the like, and wall sections 712 and 713 that demarcate the fixing surface 711. The wall section 712 is formed along the inner circumferential surface of the horizontal member fixing section 71, and the wall section 713 is formed along the corner end of the horizontal member fixing section 71, that is, the end on the vertical member fixing section 72 side. In other words, the wall section 712 is formed along the X-axis direction, which is the longitudinal direction of the horizontal member fixing section 71, and the wall section 713 is formed along the Y-axis direction, which is the short-side direction of the horizontal member fixing section 71. Similarly, the exterior surface of the vertical member fixing section 72 also includes a fixing surface 721 to which the vertical member 63 or vertical member 64 is fixed with double-sided tape or the like, and wall sections 722 and 723 that demarcate the fixing surface 721. The wall section 722 is formed along the inner circumferential surface of the vertical member fixing section 72, and the wall section 723 is formed along the corner end of the vertical member fixing section 72, that is, the end on the horizontal member fixing section 71 side. In other words, the wall section 722 is formed along the Y-axis direction, which is the longitudinal direction of the vertical member fixing section 72, and the wall section 723 is formed along the X-axis direction, which is the short-side direction of the vertical member fixing section 72.

[0022] The connecting portion 73 connects the horizontal member fixing portion 71 and the vertical member fixing portion 72 so that their respective longitudinal directions are perpendicular to each other and are at reference positions. Furthermore, as shown in Figure 10, the connecting portion 73 is configured to be elastically deformable in the proximity direction (direction of the arrow in Figure 10) as the horizontal member fixing portion 71 and the vertical member fixing portion 72 move closer to each other. The connecting portion 73 is composed of an inner circumferential connecting portion 74 and an outer circumferential connecting portion 75. As shown in Figure 8, the inner circumference connecting portion 74 includes a first inner circumference piece 741 extending from the corner end of the horizontal member fixing portion 71, a second inner circumference piece 742 extending from the corner end of the vertical member fixing portion 72, and an inner circumference curved piece 743 connecting the first inner circumference piece 741 and the second inner circumference piece 742. The first inner circumferential piece 741 and the second inner circumferential piece 742 extend from the inner circumferential portions of the horizontal member fixing portion 71 and the vertical member fixing portion 72 toward the outer corners of the frame 60 at an angle of approximately 45° with respect to the X and Y axes. For this reason, the first inner circumferential piece 741 and the second inner circumferential piece 742 are arranged approximately parallel to each other. The inner circumferential curved portion 743 is connected to the ends of the first inner circumferential portion 741 and the second inner circumferential portion 742, and is formed in a substantially arc shape in the plan view shown in Figure 8. Therefore, the first inner circumferential portion 741 and the second inner circumferential portion 742 and the inner circumferential curved portion 743 are continuous in a curved surface. The inner circumferential connecting portion 74 is formed in a roughly U-shape when viewed from the outside or inside of the room, and the corner member 70 has a slit 76 that opens to the inner surface side of the frame 60, surrounded by a first inner circumferential piece 741, a second inner circumferential piece 742, and an inner curved piece 743. The width dimension of the slit 76, that is, the distance between the first inner circumferential piece 741 and the second inner circumferential piece 742, is, for example, 2 mm. The thickness dimension of the inner circumferential connecting portion 74 in the Z-axis direction is the same as that of the wall portions 713 and 723. Therefore, on the exterior surface of the corner material 70, the exterior surfaces of the wall portions 713 and 723 and the inner circumferential connecting portion 74 are continuous and on the same plane.

[0023] The outer peripheral connecting portion 75 comprises a first outer peripheral piece 751 extending from the corner end of the horizontal member fixing portion 71, a second outer peripheral piece 752 extending from the corner end of the vertical member fixing portion 72, and an outer peripheral curved piece 753 connecting the first outer peripheral piece 751 and the second outer peripheral piece 752. The first outer peripheral piece 751 and the second outer peripheral piece 752 extend from the outer peripheral portions of the horizontal member fixing portion 71 and the vertical member fixing portion 72, along the respective longitudinal directions of the horizontal member fixing portion 71 and the vertical member fixing portion 72. Therefore, the first outer peripheral piece 751 and the second outer peripheral piece 752 extend in directions perpendicular to each other (the X-axis direction and the Y-axis direction). The outer curved portion 753 is connected to the ends of the first outer curved portion 751 and the second outer curved portion 752, and is formed in a substantially arc shape in the plan view shown in Figure 8. The thickness dimension of the outer peripheral connecting portion 75 in the Z-axis direction is greater than that of the inner peripheral connecting portion 74 and the wall portions 713 and 723. Therefore, on the exterior surface of the corner material 70, the outer peripheral connecting portion 75 protrudes further outward than the inner peripheral connecting portion 74 and the wall portions 713 and 723. Consequently, the outer peripheral connecting portion 75 has a protruding portion that extends from the surface on which the net 80 is placed. As shown in Figure 9, the outer peripheral connecting portion 75 is provided to be continuous with the guide pieces 612, 622, 632, and 642 of the upper member 61, lower member 62, and vertical members 63 and 64 fixed to the corner member 70. Thus, the outer peripheral connecting portion 75 constitutes the corner guide piece.

[0024] As shown in Figure 8, a space 77 is formed between the outer peripheral connecting portion 75 and the inner peripheral connecting portion 74, extending in the Z-axis direction. The connection portion between the wall portions 713 and 723 and the outer peripheral connecting portion 75 is formed to be an arcuate surface, and the surface that demarcates the periphery of the space 77 is configured to be a continuous curved surface. Furthermore, a retaining piece 754 is formed on the outer curved portion 753 of the outer peripheral connecting portion 75, projecting toward the space portion 77. The outer surface of the retaining piece 754 is on the same plane as the inner peripheral connecting portion 74 and the wall portions 713 and 723, but the thickness dimension of the retaining piece 754 in the Z-axis direction is smaller than that of the inner peripheral connecting portion 74 and the wall portions 713 and 723. For this reason, the retaining piece 754 is formed in a thin plate shape.

[0025] Such corner members 70 are made of an elastically deformable synthetic resin material. Furthermore, the connecting portion 73 that connects the horizontal member fixing portion 71 and the vertical member fixing portion 72 is formed by an inner circumferential connecting portion 74 which is formed in a substantially U-shape in plan view so as to form a slit 76, and an outer circumferential connecting portion 75 which is formed with a space 77 in between the inner circumferential connecting portion 74 and has an outer curved piece portion 753 which is substantially arc-shaped in plan view. As shown in Figure 10, the horizontal member fixing portion 71 and the vertical member fixing portion 72 can be elastically deformed in the direction in which they move closer to each other, that is, in the in-plane direction along the X axis and Y axis. The corner member 70 can be elastically deformed to a position where the corners 714 and 724 facing the slits 76 of the horizontal member fixing portion 71 and the vertical member fixing portion 72 come into contact with each other. Corner 714 is also the end of the first inner circumferential piece 741 on the inner circumferential surface side of the frame frame 60, and corner 724 is also the end of the second inner circumferential piece 742 on the inner circumferential surface side of the frame frame 60. Each corner 714 and 724 is a restricting portion of the present invention that comes into contact with each other when the connecting portion 73 is elastically deformed, thereby restricting further deformation.

[0026] As shown in Figure 9, the frame 60 is constructed by fixing the upper and lower horizontal members 61 and 62 to the fixing surface 711 of the horizontal member fixing part 71 of the corner member 70 using double-sided tape or the like, and fixing the vertical members 63 and 64 to the fixing surface 721 of the vertical member fixing part 72 using double-sided tape or the like. The net 80 is formed in a planar rectangular shape, and its outer edges (upper edge, lower edge, and left and right vertical edges) are attached to the upper member 61, lower member 62, and vertical members 63 and 64 of the frame 60. Specifically, the net 80 is placed on the exterior surface of the mounting pieces 611, 621, 631, and 641 of the upper member 61, lower member 62, and vertical members 63 and 64, and is attached to the frame 60 by applying single-sided tape 85 to the surface of the net 80 at the placement points. That is, one side of the single-sided tape 85 that faces the net 80, i.e., the interior side, is an adhesive layer, and this adhesive layer is fixed to the mounting pieces 611, 621, 631, and 641 through the mesh of the net 80, thereby fixing the net 80 to the mounting pieces 611, 621, 631, and 641. Therefore, the outer edge of the net 80 forms a net that is placed between the mounting pieces 611, 621, 631, and 641 and the single-sided tape 85. After attaching the net 80 to the frame 60 with the single-sided tape 85, any net 80 that extends beyond the frame 60 can be cut off using a cutter or similar tool. Specifically, by moving the cutter along the inner surface of the guide pieces 612, 622, 632, 642 and the outer peripheral connecting portion 75, the net 80 that extends beyond the single-sided tape 85 to the outer peripheral side can be easily cut off. The four corners of the net 80 are inserted into the space 77. Therefore, the corners of the net 80 are positioned on the interior side of the retaining piece 754 of the outer peripheral connecting portion 75, making it difficult for them to come loose from the space 77.

[0027] As shown in Figure 7, the screen door 6 is fitted with three pull tabs 90 and a handle tab 95. The pull tabs 90 are fixed to the interior surfaces of the upper member 61 and the left and right vertical members 63 and 64 with double-sided tape or the like. The handle tabs 95 are fixed to the interior surface of the lower member 62 with double-sided tape or the like. The pull handle component 90 is composed of a base portion 91, a pair of arm portions 92, and a handle portion 93. The base portion 91 is a plate-like portion that is fixed to the upper material 61, vertical materials 63, 64 with double-sided tape or the like. The arm portion 92 is positioned on either side of the base portion 91, and the outer peripheral end of the frame 60 is connected to the base portion 91. A claw portion 920 is formed on the arm portion 92. As shown in Figures 3, 5, and 6, the claw portion 920 has an inclined surface 921 that slopes inward toward the interior as it moves from the outer peripheral side to the inner peripheral side of the frame 60, and a contact surface 922 formed along the Z-axis direction toward the exterior side from the inner peripheral edge of the inclined surface 921, and is formed in a substantially triangular cross-section. The handle portion 93 is provided spanning between the inner circumferential ends of a pair of arm portions 92. The handle portion 93 is formed in a plate shape that protrudes inward, and is configured so that a user can grasp it with their hand.

[0028] As shown in Figure 4, the handle component 95 is composed of a base portion 96 and a handle portion 97. The base portion 96 is a plate-shaped part that is fixed to the arm portion 92 with double-sided tape or the like. The handle portion 97 is formed in a plate shape that protrudes inward and is configured so that a user can grasp it with their hand.

[0029] Next, the procedure for attaching and detaching the screen door 6 to the screen door frame 5 will be described. The screen door 6 is attached to and removed from the screen door frame 5 by elastically deforming the upper member 61, lower member 62, vertical members 63, 64 and corner members 70 (upper corner member 70A, lower corner member 70B) of the frame 60. The net 80 deforms in accordance with the elastic deformation of the frame 60. For example, the screen door 6 can be attached to the screen door frame 5 using the following procedure. As shown in Figure 11, the upper member 61 is bent, for example, inward to narrow the gap between the upper corner member 70A and the upper end of the vertical member 63 on the left side and the upper corner member 70A and the upper end of the vertical member 64 on the right side, and inserted into the vertical grooves 530 and 540 of the vertical frames 53 and 54 of the screen door frame 5. The dashed lines in Figure 11 indicate the inner circumferential surfaces 511, 521, 531, and 541 of the screen door frame 5 where the upper groove 510, lower groove 520, and vertical grooves 530 and 540 are opened. Also, the net 80, pull tab 90, and handle 95 are omitted in Figure 11. The horizontal fixing portion 71 and vertical fixing portion 72 of the upper corner member 70A are connected by elastically deformable inner circumferential connecting portion 74 and outer circumferential connecting portion 75. Therefore, in addition to the upper member 61, the upper corner member 70A and vertical members 63 and 64 can also bend, allowing the frame 60 to be deformed three-dimensionally, and the upper portions of the upper corner member 70A and vertical members 63 and 64 can be inserted into the vertical grooves 530 and 540 of the vertical frames 53 and 54. At this time, the lower portions of the vertical members 63 and 64, as well as the lower corner member 70B and lower member 62, are located on the indoor side of the screen door frame 5. In this case, the lower corner member 70B and lower member 62 also deform elastically in conjunction with the elastic deformation of the vertical members 63 and 64.

[0030] Next, the screen door 6 is lifted upwards and the upper member 61 is inserted into the upper groove 510 of the upper frame 51. For example, the handle part 90 attached to the upper member 61 is grasped by hand and lifted, and the upper member 61 and the handle part 90 are inserted into the upper groove 510. At this time, the arm part 92 of the handle part 90 elastically deforms outwards as the inclined surface 921 of the claw part 920 comes into contact with the locking part 514 of the upper frame 51. Then, when the claw part 920 overcomes the locking part 514 and is positioned in the recess 515, the arm part 92 returns to its original state as shown in Figure 3. Therefore, if the upper member 61 moves downwards and tries to come out of the upper groove 510, the contact surface 922 of the claw part 920 comes into contact with the locking part 514, thus preventing the upper member 61 from coming out of the upper groove 510. Next, the lower member 62 is bent to allow it to pass over the operator handle 43, and the gap between the lower left corner member 70B and the lower side of the vertical member 63, and the lower right corner member 70B and the lower side of the vertical member 64 is narrowed, allowing it to be inserted into the vertical grooves 530 and 540 of the vertical frames 53 and 54 of the screen door frame 5. At this time, the lower member 62 also passes over the groove section 522 of the lower frame 52 and is positioned above the lower groove 520.

[0031] Then, by pushing down the handle part 95 of the lower member 62, the screen door 6 is moved downward and the lower member 62 is inserted into the lower groove 520 of the lower frame 52, as shown in Figure 4. At this time, the lower end of the base part 96 of the handle part 95 is also positioned in the lower groove 520. Since a locking part 525 is formed on the outdoor piece 523 of the lower frame 52, the lower member 62 and the handle part 95 should be tilted diagonally and pushed between the groove compartment 522 and the locking part 525, and the lower member 62 should be inserted into the lower groove 520 while slightly curving the outdoor piece 523 and the groove compartment 522. This prevents the lower member 62 from coming out of the lower groove 520 even if the lower member 62 moves upward unintentionally, as the guide piece 622 will lock into the locking part 525. Furthermore, the pull handle parts 90 of the vertical members 63 and 64 are also inserted into the vertical grooves 530 and 540 of the vertical frames 53 and 54. In this case as well, the arm portion 92 of the pull handle part 90 elastically deforms, and the claw portion 920 moves over the locking portions 534 and 544 of the vertical frames 53 and 54 and into the recesses 535 and 545. As a result, when the vertical members 63 and 64 try to come out of the vertical grooves 530 and 540, the contact surface 922 comes into contact with the locking portions 534 and 544, thus preventing the vertical members 63 and 64 from coming out of the vertical grooves 530 and 540. The above procedure is just one example of how to attach the screen door 6 to the screen door frame 5. Alternatively, the handle parts 90 of the vertical members 63 and 64 may be inserted into the vertical grooves 530 and 540 of the vertical frames 53 and 54, and then the screen door 6 may be moved downwards to insert the bottom member 62 and the handle part 95 into the bottom groove 520.

[0032] On the other hand, when removing the screen door 6 from the screen door frame 5, such as when cleaning the screen door 6 or when the net 80 is damaged, the procedure should be the reverse of the installation procedure. For example, grasp the handle part 95 of the bottom member 62 with your hand and move it upward, then pull it inward to flex the bottom member 62, allowing it to move over the groove section 522 and into the room. Alternatively, push the handle part 93 of the pull parts 90 of the vertical members 63 and 64 outward to release the locking of the claw part 920 and the locking parts 534 and 544. Next, the lower member 62 and the lower corner member 70B are elastically deformed to detach the lower corner member 70B and the lower sides of the vertical members 63 and 64 from the vertical grooves 530 and 540 of the vertical frames 53 and 54, and the lower member 62 is moved towards the interior side, overcoming the operator handle 43. Furthermore, the handle portion 93 of the pull handle part 90 of the upper member 61 is pushed outwards to release the locking of the claw portion 920 and the locking portion 514, and the upper member 61 is moved downward. Then, the upper material 61 and upper corner material 70A are elastically deformed to separate the upper corner material 70A and the upper sides of the vertical materials 63 and 64 from the vertical grooves 530 and 540 of the vertical frames 53 and 54, and the screen door 6 is removed from the screen door frame 5.

[0033] [Effects of the Embodiment] Since the corner members 70 of the frame 60 are configured to be elastically deformable in the direction in which the horizontal member fixing part 71 and the vertical member fixing part 72 are close together, the corner members 70 can also be elastically deformed in addition to the upper member 61, lower member 62, and vertical members 63 and 64. As a result, when attaching or detaching the screen door 6 to the screen door frame 5, the frame 60 of the screen door 6 becomes more flexible, making it easier to attach and detach the screen door 6.

[0034] The corner member 70 is equipped with corner portions 714 and 724, which are restricting portions that come into contact with each other and restrict further elastic deformation when the horizontal member fixing portion 71 and the vertical member fixing portion 72 deform in a direction that brings them closer together. Therefore, the amount of deformation of the corner member 70 can be restricted to below a predetermined amount, and plastic deformation or breakage of the corner member 70 can be reliably prevented.

[0035] Since the connecting portion 73 includes an inner circumferential connecting portion 74 and an outer circumferential connecting portion 75, it is possible to realize a structure that ensures appropriate rigidity as a connecting portion 73 while also allowing for elastic deformation. The inner circumferential connecting portion 74 is formed in a substantially U-shape in plan view, comprising a first inner circumferential piece 741, a second inner circumferential piece 742, and an inner circumferential curved piece 743, and has an open slit 76 on the inner circumferential side. Therefore, during elastic deformation, the first inner circumferential piece 741 and the second inner circumferential piece 742 can be brought into contact to form a restricting portion, allowing the connecting portion 73 with a restricting portion to be realized with a simple structure and reducing costs. Furthermore, since the inner circumference connecting portion 74 connects the inner circumference of the horizontal fixing portion 71 and vertical fixing portion 72 of the corner member 70, if it is formed along the inner circumference surface of the corner member 70, it is not possible to secure the required length, and it would be necessary to deform it significantly, making it difficult to secure both rigidity and deformation. In contrast, the inner circumference connecting portion 74 of this embodiment is equipped with a first inner circumference piece 741 and a second inner circumference piece 742 that extend from the inner circumference to the outer circumference of the corner member 70. When deforming to the restricted position where the corners 714 and 724 abut, the inner circumference curved piece 743, which is located away from the corners 714 and 724 towards the outer circumference, is deformed, thus suppressing the amount of deformation of the inner circumference curved piece 743. Therefore, the inner circumference connecting portion 74 can maintain rigidity while also securing the necessary amount of deformation.

[0036] The outer peripheral connecting portion 75 comprises a first outer peripheral piece 751, a second outer peripheral piece 752, and an outer peripheral curved piece 753, allowing for a simple structure and reduced costs. Furthermore, since the outer peripheral connecting portion 75 is formed along the outer circumference of the corner material 70, its length can be increased, allowing for the distribution of stress during elastic deformation, thus ensuring rigidity while also ensuring sufficient deformation. Furthermore, since the outer surface of the corner portion of the corner material 70 is formed in an arc shape by the outer curved piece 753 rather than by a perpendicular corner, it is possible to prevent the frame frame 60 from damaging the screen door frame 5 when inserting the frame frame 60 into the upper groove 510, lower groove 520, vertical groove 530, 540 of the screen door frame 5.

[0037] Since a space 77 is formed between the outer peripheral connecting portion 75 and the inner peripheral connecting portion 74, the outer peripheral connecting portion 75 and the inner peripheral connecting portion 74 can be easily deformed. Since a space 77 is formed in the corner material 70, the corner portion of the net 80 can be inserted into the space 77 and held in place. Furthermore, since a retaining piece 754 is formed in the outer peripheral connecting portion 75, the net 80 pushed into the space 77 can be held down by the retaining piece 754, preventing the net 80 from lifting up.

[0038] The extension dimension L1 in the depth direction of the guide pieces 612, 622, 632, and 642 of the upper material 61, lower material 62, and vertical material 63 and 64 of the frame 60 is made larger than the thickness dimension L2 in the depth direction of the net 80 and the single-sided tape 85. This prevents the single-sided tape 85 from coming into contact with the screen door frame 5 and peeling off when attaching or detaching the screen door 6 to the upper groove 510, lower groove 520, and vertical groove 530 and 540. Since the net 80 is fixed to the frame 60 with single-sided tape 85, the workability of attaching the net 80 to the frame 60 can be improved compared to when the net 80 is attached with adhesive, and the productivity of the screen door 6 can be improved. Furthermore, if the net 80 is attached to the frame 60 with adhesive, when the screen door 6 is removed from the screen door frame 5, the adhesive will be exposed on the surface of the screen door 6, reducing its aesthetic appeal. In contrast, in this embodiment, the net 80 is attached to the frame 60 with single-sided tape 85, so when the screen door 6 is removed, the adhesive layer of the single-sided tape 85 is not exposed, and the support layer that supports the adhesive layer, i.e., the base material of the single-sided tape 85, is exposed, thus improving the aesthetic appeal of the screen door 6.

[0039] Guide pieces 612, 622, 632, and 642 of the upper material 61, lower material 62, and vertical material 63 and 64, as well as the outer peripheral connecting portion 75 of the corner material 70, are provided along the outer circumference of the frame 60. These can be used as guides when cutting the outer edge of the net 80 with a cutter or the like. This improves the ease of cutting the net 80 and further increases the productivity of the screen door 6.

[0040] Since the net 80 is attached to the exterior surface of the frame 60, the pull handle 90 and handle 95 can be attached to the interior surface of the frame 60 without interfering with the net 80.

[0041] [Differentiation] The corner member 70 is not limited to the structure of the embodiment described above. For example, the restricting portion that restricts the amount of elastic deformation of the corner member 70 may be formed on the upper member 61, lower member 62, vertical member 63, 64 instead of the corner member 70, or the restricting portion may not be provided at all. Furthermore, the connecting portion 73 is not limited to being composed of an inner circumferential connecting portion 74 and an outer circumferential connecting portion 75, but may be composed of only one of the inner circumferential connecting portion 74 or the outer circumferential connecting portion 75. Also, the connecting portion may be composed of an intermediate connecting portion that connects the intermediate portions of the inner and outer circumferences of the corner ends of the horizontal member fixing portion 71 and the vertical member fixing portion 72. Furthermore, the specific structures of the inner circumferential connecting portion 74 and the outer circumferential connecting portion 75 are not limited to the above embodiment. For example, the inner circumferential connecting portion 74 is not limited to being formed in a substantially U-shape when viewed from the front in the direction of depth, but may be formed in an arc shape when viewed from the front. Similarly, the outer circumferential connecting portion 75 may be formed in a quarter-circumferential shape when viewed from the front. In other words, the connecting portion 73 of the corner member 70 is configured to be elastically deformable in the direction of proximity, where the horizontal member fixing portion 71 and the vertical member fixing portion 72 move closer to each other from a reference position where the horizontal member fixing portion 71 and the vertical member fixing portion 72 are arranged orthogonally, and when the force that deforms the corner member 70 is released, it is sufficient that the horizontal member fixing portion 71 and the vertical member fixing portion 72 can be returned to and maintained in the reference position. Furthermore, the frame may use corner members that do not elastically deform in the direction of proximity, with the horizontal member fixing part 71 and the vertical member fixing part 72 directly connected, or it may be constructed by directly connecting the upper and lower horizontal members and the left and right vertical members without providing corner members 70.

[0042] The upper and lower horizontal members and left and right vertical members of the frame 60 of the screen door 6 are not limited to the structure of the embodiment described above. For example, a structure with a U-shaped cross-section, comprising a mounting piece 631, an outer peripheral guide piece 632, and an inner peripheral guide piece 633, may be adopted, as shown in Figure 12 for the vertical member 63B. Alternatively, a structure with an L-shaped cross-section, comprising a mounting piece 631 and an inner peripheral guide piece 633, may be adopted, as shown in Figure 13 for the vertical member 63C. If guide pieces 632 and 633 are formed on the outer and inner sides, respectively, as in the case of the vertical member 63B, it is possible to more reliably prevent the single-sided tape 85 adhered to the mounting piece 631 from coming into contact with the screen door frame 5. Therefore, when inserting the screen door 6 into the groove of the screen door frame 5, it is possible to reliably prevent the single-sided tape 85 from coming into contact with the screen door frame 5 and peeling off. Furthermore, if the vertical members 63B and 63C are equipped with guide pieces 633 on the inner circumference side, the inner circumference side of the single-sided tape 85 can be covered with the guide pieces 633, preventing the single-sided tape 85 from being visible from the inner surface of the screen door 6.

[0043] The tape used to secure the net 80 to the frame 60 is not limited to single-sided tape; double-sided tape may be used, which is placed between the net 80 and the mounting pieces 611, 621, 631, and 641. In this case, decorative tape may be applied to the surface of the net 80 to cover the adhesive surface of the double-sided tape to which the net 80 is secured.

[0044] The screen door frame 5 may be framed independently of the window frame 2. Furthermore, the screen door frame 5 is not limited to being a separate structure from the window frame 2; the window frame 2 may also be provided with a structure that effectively functions as a screen door frame. The building component of the present invention is not limited to vertical sliding windows 1, but may also be a casement window or an outward-opening window. Furthermore, the fixed screen door is not limited to one installed on the interior side of the shoji screen, but may also be installed on the exterior side of the shoji screen in building components having shoji screens that open and close inward, such as inward-opening windows or tilt-and-turn windows. The screen body is not limited to insect screens. For example, the screen of the screen body may be a screen other than Net 80. For example, it may be a sheet-like light-blocking screen, or any screen such as net, cloth, or film that can follow the deformation of the rectangular frame when the frame is deformed. The sheet-like screen may be fixed to the frame with double-sided tape, or the outer edge of the screen may be formed into a net-like structure and fixed to the frame with single-sided tape.

[0045] [Summary of the invention] The present invention provides a screen body comprising a rectangular frame and a screen held by the frame, wherein the frame comprises upper and lower horizontal members and left and right vertical members, and the horizontal members and vertical members each comprise a mounting piece to which the screen is fixed by tape and a guide piece extending in the depth direction from the mounting piece, wherein the extension dimension of the guide piece in the depth direction is greater than the thickness dimension of the screen and the tape in the depth direction. By making the extension dimensions of the guide pieces on the horizontal and vertical members of the frame larger than the thickness dimensions of the screen and tape in the same direction, it is possible to prevent the screen and tape from coming into contact with the screen frame and peeling off when inserting or removing the screen into or from the groove of the screen frame. Since the screen is secured to the frame with tape, the ease of attaching the screen to the frame is improved compared to when the screen is attached with adhesive, thus increasing the productivity of the screen assembly. When a net-like screen, such as a window screen, is attached to a frame with adhesive, the adhesive is exposed on the surface of the screen when it is removed from the frame, reducing its aesthetic appeal. In contrast, attaching the screen to the frame with tape improves the aesthetic appeal of the screen.

[0046] In the screen body of the present invention, the screen preferably comprises a net disposed between the mounting piece and the tape, and the tape is preferably a single-sided tape with an adhesive layer on the side facing the net. By placing the net, which is provided on the outer edge of the screen, on the surface of the mounting piece of the frame and applying single-sided tape over it, the adhesive layer of the single-sided tape adheres to the mounting piece through the mesh of the net, making it easy to attach the screen net to the frame. Furthermore, the adhesive layer of the single-sided tape is not exposed on the surface of the screen body, but the support layer that supports the adhesive layer, i.e., the base material of the single-sided tape, is exposed, thus improving the aesthetic appearance of the screen body.

[0047] In the screen body of the present invention, it is preferable that the guide piece extends in the depth direction from the outer peripheral end of the frame at the mounting piece. Since the guide piece extends in the depth direction from the outer edge of the mounting piece, it can be used as a guide when cutting the outer edge of the screen with a cutter or similar tool. This improves the ease of cutting the screen and further increases the productivity of the screen body.

[0048] In the screen body of the present invention, the frame comprises upper and lower horizontal members, left and right vertical members, and corner members connecting the horizontal members and the vertical members, and preferably the corner members have corner-side guide pieces that are continuous with the guide pieces. Since the corner piece has a corner-side guide piece that is continuous with the guide piece, when cutting the outer edge of the screen along the guide piece, it is possible to cut continuously from the guide piece of the horizontal member through the corner-side guide piece to the guide piece of the vertical member, improving the cutting workability of the screen and further improving the productivity of the screen body.

[0049] In the screen body of the present invention, it is preferable that the guide piece extends in the depth direction from the inner circumference end of the frame at the mounting piece. If the mounting piece is provided with an inner-circumferential guide piece extending in the depth direction from the inner-circumferential end of the frame, the inner side of the tape that secures the screen can be covered with the guide piece, preventing the tape from being visible from the inner surface of the screen body.

[0050] In the screen body of the present invention, it is preferable that the screen is an insect-proof net and the screen body is a screen door. This invention provides a screen body that can be easily attached to and detached from a screen frame, and is particularly suitable for use as a fixed screen door.

[0051] The present invention relates to a joinery comprising a joinery frame, a sliding door attached to the joinery frame so as to be openable and closable, a screen frame attached to the joinery frame, and a screen body detachably attached to the screen frame, wherein the screen frame is formed in a rectangular shape by comprising upper and lower horizontal frames and left and right vertical frames, the horizontal frames and the vertical frames are provided with grooves that open to the inner circumferential surface of the screen frame, and the frame of the screen body is inserted into and held in the grooves of the screen frame. Because the screen body is provided, when inserting or removing the screen body from the groove of the screen frame, it is possible to prevent the screen or tape from coming into contact with the screen frame and peeling off. In addition, since the screen is fixed to the frame with tape, the workability of attaching the screen to the frame can be improved, and the productivity of the screen body can be increased. Furthermore, since the screen is attached to the frame with tape, the aesthetic design of the screen door can be improved. [Explanation of Symbols]
