Description

Technical Field

[0001] The present invention relates to a fitting part for a building fitting and an attachment structure of the fitting part for a building fitting.

Background Art

[0002] To attach a fitting part for a building fitting to a shaped material such as a frame material or a sash material, there is a method of arranging the fitting part for a building fitting in a mounting groove formed in the shaped material. The fitting part for a building fitting is provided with a base that cannot be inserted into the mounting groove, an insertion part that protrudes from the base and can be inserted into the mounting groove, and a bulging part that protrudes from the insertion part to the periphery. When attaching this fitting part for a building fitting to a shaped material, the insertion part may be moved along the mounting groove with the base positioned on one surface side of the shaped material and the bulging part positioned on the other surface side. That is, in this attachment method, since the sandwiched mounting parts of the shaped material located on both sides of the mounting groove are arranged between the reference surface and the bulging part, movement of the fitting part for a building fitting along the direction orthogonal to the surface of the shaped material can be blocked (see, for example, Patent Document 1).

For convenience, the terms "depth direction" and "face direction" may be used below. The depth direction is the direction along the depth of the joinery to which the joinery component is to be attached, as shown by arrow A in the figure. The surface along the depth direction may be referred to as the depth surface. The face direction is the direction along the vertical direction perpendicular to the depth direction, in the case of components that extend horizontally, such as bottom frames. In the case of components that extend vertically, such as vertical frames, the face direction is the direction along the horizontal direction perpendicular to the depth direction. The surface along the face direction may be referred to as the face surface.

[0013] Figures 1 to 3 show a window with components attached using a mounting structure that is an embodiment of the present invention. The window shown here is called a sliding window and comprises a frame 10, a sash 20 that opens outward from the frame 10, and a fixed screen door 30 mounted on the interior side of the frame 10, beyond the sash 20. The upper frame 11, lower frame 12, and left and right vertical frames 13 that make up the frame 10 are each extruded profiles molded from resin. In the illustrated example, the upper frame 11, lower frame 12, and vertical frames 13, which have the same cross-sectional shape as each other, are used and the frame 10 is constructed by welding them together via 45° joint surfaces formed at each end. The sash 20 is constructed by attaching an upper frame 22, a lower frame 23, and left and right vertical frames 24 around the four sides of a panel 21 made of glass or the like, and is installed in the part of the frame 10 that is on the exterior side. The upper frame 22, lower frame 23, and left and right vertical frames 24 are each extruded profiles molded from resin. The sliding window shown in the figure is configured so that the sash 20 is opened and closed by operating an operating member 1 attached to the reinforcing member 14 of the lower frame 12. The fixed screen door 30 is constructed as shown in Figures 4 to 9 by arranging a mesh body 34 stretched inside the upper screen door frame 31, lower screen door frame 32, and left and right vertical screen door frames 33 which are assembled around the four sides. The upper screen door frame 31, lower screen door frame 32, and left and right vertical screen door frames 33 are extruded profiles molded from metal such as aluminum alloy, and their ends are connected to each other by upper corner members 35 and lower corner members 36 molded from resin. The upper corner members 35, located at both upper corners, have locking holes 35a on their upper surfaces and connect the upper screen door frame 31 to the left and right vertical screen door frames 33, respectively. The lower corner members 36, located at both lower corners, are equipped with stoppers 36a on their outer peripheral sides and connect the lower screen door frame 32 to the left and right vertical screen door frames 33, respectively. The stoppers 36a are movable forward and backward toward the outer periphery and are constantly biased toward the outer periphery by the spring force of the built-in spring 36b. Reference numeral 36c in the figure indicates an operating part for retracting the stopper 36a against the spring force of the built-in spring 36b.This fixed screen door 30 is installed inside the frame 10 in a part that is on the interior side of the shoji screen 20, by engaging upper anti-detachment parts (joinery parts) 40 attached to both ends of the upper frame 11 with locking holes 35a of the upper corner members 35, and by engaging lower anti-detachment parts (joinery parts) 50 provided on the lower part of the left and right vertical frames 13 with stoppers 36a of the lower corner members 36.

[0014] In this embodiment, as casement windows, two types are available as the same product series: one with two glass plates as panel 21A of the sash 20 (hereinafter referred to as the first casement window WA when distinguishing between them), as shown in Figures 2 and 3, and another with three glass plates as panel 21B of the sash 20 (hereinafter referred to as the second casement window WB when distinguishing between them), as shown in Figures 10 and 11. The two types of casement windows WA and WB differ in the dimensions along the depth direction of the upper frame (shaped material) 11A, 11B, lower frame 12A, 12B, and left and right vertical frame (shaped material) 13A, 13B that constitute the frame 10A, 10B, according to the thickness direction dimensions of the panels 21A, 21B, and the dimensions along the depth direction of the upper stile 22A, 22B, lower stile 23A, 23B, and left and right vertical stile 24A, 24B that constitute the sash 20A, 20B. Furthermore, the upper frames 11A, 11B, lower frames 12A, 12B, and left and right vertical frames 13A, 13B have different plate thicknesses. However, the shapes of the frame bodies 10A, 10B as seen from the interior side are configured to be almost identical for the first casement window WA and the second casement window WB. Therefore, the two types of casement windows WA and WB share the same fixed screen door 30, and the upper anti-detachment parts 40 and lower anti-detachment parts 50 for arranging the fixed screen door 30 on the frame bodies 10A, 10B are also of the same shape and are installed at the same positions on the frame bodies 10A, 10B. The detailed configurations of the upper frames 11A, 11B, lower frames 12A, 12B, and vertical frames 13A, 13B that constitute each frame body 10A, 10B, as well as the detailed configurations of the upper anti-detachment parts 40 and lower anti-detachment parts 50, will be described below, along with a description of the characteristic features of the present invention.

[0015] As shown in Figures 2, 12(a), and 13(a), the first upper frame 11A, first lower frame 12A, and first vertical frame 13A that constitute the first frame body 10A of the first sliding window WA each have a first frame body 11Aa, 12Aa, 13Aa and a first door-stop wall portion 11Ab, 12Ab, 13Ab, respectively. The first frame body 11Aa, 12Aa, 13Aa are roughly rectangular cylindrical shapes with their longitudinal side running along the depth direction. On the exterior-facing surfaces of the first frame body 11Aa, 12Aa, 13Aa, first outer peripheral wall portions 11Ac, 12Ac, 13Ac, which are hollow and protrude outwards from the outer peripheral side. The first frame bodies 11Aa, 12Aa, 13Aa have first visible mounting fin portions 11Ad, 12Ad, 13Ad that protrude outward from the outer surface of the outer surface. The first frame bodies 11Aa, 12Aa, 13Aa have first visible mounting fin portions 11Ae, 12Ae, 13Ae that are on the outer edge of the visible surface facing the interior, and these protrude inward from the interior edge. The first door-end wall portions 11Ab, 12Ab, 13Ab are hollow in shape that protrude inward from the portion located on the interior side of the inner surface of the first frame bodies 11Aa, 12Aa, 13Aa. The inner surface of the first door-end wall portions 11Ab, 12Ab, 13Ab has first visible surfaces 11Af, 12Af, 13Af that are flat along the width direction. A first sealing member C1 is attached to the inner circumference portion of the exterior-facing visible surface of the first door-type wall section 11Ab, 12Ab, and 13Ab. The first sealing member C1 is intended to ensure watertightness and airtightness between the sliding door 20 and the visible surface of the sliding door 20 that faces the interior.

[0016] As shown in Figures 10, 12(b), and 13(b), the second upper frame (shaped material) 11B, second lower frame 12B, and second vertical frame 13B that constitute the second frame body 10B of the second sliding window WB each have a second frame body 11Ba, 12Ba, 13Ba and a second door-end wall portion 11Bb, 12Bb, 13Bb, respectively. The second frame body 11Ba, 12Ba, 13Ba are roughly rectangular tubular shapes with their longitudinal side running along the depth direction. On the exterior-facing surfaces of the second frame body 11Ba, 12Ba, 13Ba, second outer peripheral wall portions 11Bc, 12Bc, 13Bc protrude outwards from the outer peripheral portion, forming a hollow structure. The outer-circumferential faces of the second frame bodies 11Ba, 12Ba, and 13Ba have second visible mounting fin portions 11Bd, 12Bd, and 13Bd protruding outwards. The outer-circumferential edges of the visible faces of the second frame bodies 11Ba, 12Ba, and 13Ba facing the interior have second visible mounting fin portions 11Be, 12Be, and 13Be provided facing inwards. The second door-end wall portions 11Bb, 12Bb, and 13Bb are hollow in shape, protruding inwards from the portion located on the interior side of the inner-circumferential faces of the second frame bodies 11Ba, 12Ba, and 13Ba. The inner-circumferential sides of the second door-end wall portions 11Bb, 12Bb, and 13Bb have second visible surfaces 11Bf, 12Bf, and 13Bf that are flat along the width direction. A second sealing member C2 is attached to the inner circumference portion of the exterior-facing visible surface of the wall sections 11Bb, 12Bb, and 13Bb for the second door. The second sealing member C2 is intended to ensure watertightness and airtightness between the sliding door 20 and the visible surface of the sliding door 20 that faces the interior.

[0017] As is clear from the diagram, the second upper frame 11B, second lower frame 12B, and second vertical frame 13B are configured to have larger dimensions along the depth direction than the first upper frame 11A, first lower frame 12A, and first vertical frame 13A. Furthermore, the respective plate thicknesses of the second upper frame 11B, second lower frame 12B, and second vertical frame 13B are configured to be larger than those of the first upper frame 11A, first lower frame 12A, and first vertical frame 13A. To give specific examples, the second upper frame 11B, second lower frame 12B, and second vertical frame 13B are configured to have a plate thickness of 2.4 mm, while the first upper frame 11A, first lower frame 12A, and first vertical frame 13A are configured to have a plate thickness of 1.8 mm. Furthermore, the dimensions along the depth direction from the outer surface of the second outer peripheral wall portions 11Bc, 12Bc, 13Bc to the second visible mounting fin portions 11Bd, 12Bd, 13Bd are the same as the dimensions along the depth direction from the outer surface of the first outer peripheral wall portions 11Ac, 12Ac, 13Ac to the first visible mounting fin portions 11Ad, 12Ad, 13Ad. Also, the dimensions along the depth direction of the second visible surfaces 11Bf, 12Bf, 13Bf are the same as the dimensions along the depth direction of the first visible surfaces 11Af, 12Af, 13Af.

[0018] On the other hand, the dimensions of the second upper frame 11B, second lower frame 12B, and second vertical frame 13B along the visible direction are the same as those of the first upper frame 11A, first lower frame 12A, and first vertical frame 13A. The dimensions along the visible direction from the inner surface of the second frame body 11Ba, 12Ba, 13Ba to the second visible surfaces 11Bf, 12Bf, 13Bf of the second door-end wall section 11Bb, 12Bb, 13Bb are also the same as the dimensions along the visible direction from the inner surface of the first frame body 11Aa, 12Aa, 13Aa to the first visible surfaces 11Af, 12Af, 13Af of the first door-end wall section 11Ab, 12Ab, 13Ab.

[0019] The upper anti-detachment component 40 restricts the movement of the upper end of the fixed screen door 30 relative to the frame 10 by being inserted into the locking hole 35a of the upper corner member 35. As shown in Figures 14 and 15, the upper anti-detachment component 40 of this embodiment has an upper base (base) 41, an upper insertion projection 42, an upper insertion part (insertion part) 43, two upper bulging parts (bulging parts) 44, a first restricting part (restricting part) 45, and a second restricting part (restricting part) 46, and is integrally molded from resin.

[0020] The upper base 41 has a plate-like shape with a roughly rectangular outer form. In this embodiment, the portion of the upper base 41 that is on one end side of the central plane that bisects the longitudinal side is configured to be roughly horizontal, while the portion that is on the other end side of the central plane is configured to be slightly inclined toward the outer circumference. The upper insertion projection 42 is the portion that is inserted into the locking hole 35a of the upper corner member 35, and protrudes toward the inner circumference from the inner surface of the upper base 41. As is clear from the figure, the upper insertion projection 42 is provided off-center on the one end side of the upper base 41 that is horizontal. The upper insertion portion 43 protrudes toward the outer circumference from the outer surface (reference plane) 41a of the upper base 41, and, like the upper insertion projection 42, is provided off-center on the one end side of the upper base 41. The upper insertion portion 43 has a cross-sectional shape in which the dimension along the short side of the upper base 41 is smaller than the dimension along the long side of the upper base 41, and is positioned on a central plane that bisects the short side of the upper base 41. The projection dimension of the upper insertion portion 43 from the outer peripheral surface 41a of the upper base 41 is greater than the plate thickness of the second upper flat plate portion 11Bg that constitutes the second visible surface 11Bf in the second upper frame 11B described above.

[0021] The upper bulge portion 44 protrudes from both sides of the protruding end of the upper insertion portion 43. The width of the upper bulge portion 44 is smaller than that of the upper base 41. The upper bulge portion 44 forms upper opposing surfaces 47 on both sides of the upper insertion portion 43. The upper opposing surfaces 47 face the outer peripheral surface 41a of the upper base 41 and have a first upper opposing surface portion (first clamping portion) 47a, an upper guide surface portion (guide surface) 47b, a second upper opposing surface portion (second clamping portion) 47c, and an upper introduction surface portion 47d. The first upper opposing surface portion 47a and the second upper opposing surface portion 47c are planes along the outer peripheral surface 41a of the upper base 41, and the upper guide surface portion 47b is a plane that is inclined to be continuous between the first upper opposing surface portion 47a and the second upper opposing surface portion 47c. The upper introduction surface portion 47d is a plane continuous with the end of the second upper opposing surface portion 47c, and is inclined so as it moves away from the second upper opposing surface portion 47c, it gradually becomes more peripheral. The distance between the first upper opposing surface portion 47a and the peripheral surface 41a of the upper base 41 is set such that the first upper flat plate portion 11Ag, which constitutes the first visible surface 11Af of the first upper frame 11A, can be inserted through it, but the second upper flat plate portion 11Bg of the second upper frame 11B cannot be inserted through it. The distance between the second upper opposing surface portion 47c and the peripheral surface 41a of the upper base 41 is set such that the second upper flat plate portion 11Bg of the second upper frame 11B can be inserted through it. To give specific numerical examples, the distance between the first upper opposing surface portion 47a and the outer peripheral surface 41a of the upper base 41 is configured to be 2.1 mm, and the distance between the second upper opposing surface portion 47c and the outer peripheral surface 41a of the upper base 41 is configured to be 2.7 mm. These upper opposing surfaces 47 are provided such that the first upper opposing surface portion 47a is on the central side of the upper base 41, and the upper introduction surface portion 47d is on one end side of the upper base 41.

[0022] The first restricting portion 45 and the second restricting portion 46 each protrude outward from the outer peripheral surface 41a of the upper base 41. The first restricting portion 45 has a first restricting surface 45a perpendicular to the outer peripheral surface 41a and is located approximately in the center of the other end edge on the outer peripheral surface 41a. The second restricting portion 46 extends along the shorter side of the upper base 41 and has second restricting portions 46a at both ends and is located slightly closer to one end than the first restricting portion 45 on the outer peripheral surface.

[0023] As shown in Figure 16(a), the first upper frame 11A to which the above-mentioned upper anti-detachment component 40 is attached is provided with a first upper mounting groove (through groove) 2Aa and a first upper insertion hole (through hole) 2Ab in the first upper flat plate portion 11Ag which constitutes the first visible surface 11Af of the first door stop wall portion 11Ab. The first upper mounting groove 2Aa is a through hole with a width that allows the upper insertion portion 43 of the upper anti-detachment component 40 to be inserted, but prevents the two upper bulging portions 44 from being inserted, and is formed to be an elongated hole along the longitudinal side of the first upper frame 11A. This first upper mounting groove 2Aa extends toward the center with its closed end face aligned at a distance d1 from the first visible surface 13Af of the first door stop wall portion 13Ab provided on the first vertical frame 13A. This distance d1 is the position in which the upper insertion projection 42 can be inserted into the locking hole 35a of the upper corner member 35 provided on the fixed screen door 30 when the upper insertion portion 43 of the upper anti-detachment component 40 is placed in the first upper mounting groove 2Aa. The first upper insertion hole 2Ab is a through hole with a width that allows the two upper bulging portions 44 and the second limiting portion 46 of the upper anti-detachment component 40 to be inserted, but prevents the upper base 41 from being inserted, and is formed in a part that is closer to the center than the first upper mounting groove 2Aa. The first upper mounting groove 2Aa and the first upper insertion hole 2Ab are in communication with each other, and the distance d2 between the closed end face of the first upper mounting groove 2Aa and the closed end face of the first upper insertion hole 2Ab is formed to allow the upper insertion portion 43 and the first limiting portion 45 of the upper anti-detachment component 40 to be inserted. The distance d3 from the closed end face of the first upper mounting groove 2Aa to the first upper insertion hole 2Ab is configured to be greater than the total length of the upper opposing surface 47 provided on the upper detachment prevention component 40, that is, the sum of the dimensions of the upper introduction surface portion 47d, the second upper opposing surface portion 47c, the upper guide surface portion 47b, and the first upper opposing surface portion 47a.

[0024] On the other hand, the second upper frame 11B to which the upper anti-detachment component 40 is attached is provided with a second upper mounting groove (insertion groove) 2Ba and a second upper insertion hole (insertion hole) 2Bb in the second upper flat plate portion 11Bg which constitutes the second visible surface 11Bf of the second door stop wall portion 11Bb, as shown in Figure 16(b). The second upper mounting groove 2Ba is a through hole with a width that allows the upper insertion portion 43 of the upper anti-detachment component 40 to be inserted, but prevents the two upper bulging portions 44 from being inserted, and is formed to be an elongated hole along the longitudinal side of the second upper frame 11B. This second upper mounting groove 2Ba extends toward the center with its closed end face aligned at a distance d1 from the second visible surface 13Bf of the second door stop wall portion 13Bb provided on the second vertical frame 13B. The second upper insertion hole 2Bb is a through hole with a width that allows the two upper bulges 44 and the second limiting portion 46 of the upper anti-detachment component 40 to be inserted, but prevents the upper base 41 from being inserted. It is formed as an elongated hole along the longitudinal side of the second upper frame 11B in a portion that is closer to the center than the second upper mounting groove 2Ba. The second upper mounting groove 2Ba and the second upper insertion hole 2Bb are in communication with each other, and the distance d2 between the closed end face of the second upper mounting groove 2Ba and the closed end face of the second upper insertion hole 2Bb is formed to allow the upper insertion portion 43 and the first limiting portion 45 of the upper anti-detachment component 40 to be inserted. The distance d4 from the closed end face of the second upper mounting groove 2Ba to the second upper insertion hole 2Bb is configured to match the sum of the dimensions of the upper introduction surface portion 47d and the second upper opposing surface portion 47c provided on the upper anti-detachment component 40. In other words, the second upper mounting groove 2Ba provided in the second upper frame 11B is configured such that the position from the second visible surface 13Bf of the second vertical frame 13B to the closed end surface coincides with the position from the first visible surface 13Af of the first vertical frame 13A to the closed end surface in the first upper mounting groove 2Aa provided in the first upper frame 11A, while the distance d4 from the closed end surface to the second upper insertion hole 2Bb is shorter than the distance d3 from the closed end surface to the first upper insertion hole 2Ab of the first upper mounting groove 2Aa.

[0025] In other words, in the second upper frame 11B, the distance d4 along the longitudinal axis of the portions located on both sides of the second upper mounting groove 2Ba (the clamped portions, hereinafter referred to as the second upper clamped portions 2Bc) is set to be approximately equal to the sum of the dimensions of the upper introduction surface portion 47d and the second upper opposing surface portion 47c provided on the upper anti-detachment component 40. In contrast, in the first upper frame 11A, the distance d3 along the longitudinal axis of the portions located on both sides of the first upper mounting groove 2Aa (the clamped portions, hereinafter referred to as the first upper clamped portions 2Ac) is set to be greater than the sum of the dimensions of the upper introduction surface portion 47d, the second upper opposing surface portion 47c, the upper guide surface portion 47b, and the first upper opposing surface portion 47a provided on the upper anti-detachment component 40.

[0026] Therefore, when attaching the upper anti-detachment component 40 to the first upper frame 11A, inserting the first upper clamped portion 2Ac from the upper introduction surface portion 47d between the upper base 41 and the upper opposing surface 47 and positioning the upper insertion portion 43 in the first upper mounting groove 2Aa will result in the first upper clamped portion 2Ac being positioned between the outer peripheral surface 41a of the upper base 41 and the first upper opposing surface portion 47a, as shown in Figure 17(a), thus preventing the upper anti-detachment component 40 from moving along the viewing direction relative to the first upper frame 11A. Furthermore, when the upper insertion portion 43 of the upper anti-detachment component 40 is positioned in the first upper mounting groove 2Aa, the first restricting portion 45 and the second restricting portion 46 are positioned in the first upper insertion hole 2Ab. This prevents the upper anti-detachment component 40 from moving along the viewing direction relative to the first upper frame 11A.

[0027] Similarly, when attaching the upper anti-detachment component 40 to the second upper frame 11B, as shown in Figure 17(b), by inserting the second upper clamped portion 2Bc between the upper base 41 and the upper opposing surface 47 from the upper introduction surface portion 47d and positioning the upper insertion portion 43 in the second upper mounting groove 2Ba, the second upper clamped portion 2Bc is positioned between the outer peripheral surface 41a of the upper base 41 and the second upper opposing surface portion 47c, thereby preventing the upper anti-detachment component 40 from moving along the viewing direction relative to the second upper frame 11B. Furthermore, when the upper insertion portion 43 of the upper anti-detachment component 40 is positioned in the second upper mounting groove 2Ba, the first limiting portion 45 and the second limiting portion 46 are positioned in the second upper insertion hole 2Bb. This prevents the upper anti-detachment component 40 from moving along the viewing direction relative to the second upper frame 11B.

[0028] As described above, the closed end face of the first upper mounting groove 2Aa provided on the first upper frame 11A coincides with a distance d1 from the first visible surface 13Af of the first door stop wall portion 13Ab, and the closed end face of the second upper mounting groove 2Ba provided on the second upper frame 11B coincides with a distance d1 from the second visible surface 13Bf of the second door stop wall portion 13Bb. Therefore, if fixed screen doors 30 of the same shape are arranged, the upper insertion projection 42 of the upper detachment prevention part 40 can be inserted into the locking hole 35a of the upper corner member 35 in either the first frame body 10A or the second frame body 10B.

[0029] The lower anti-detachment component 50 restricts the movement of the lower end of the fixed screen door 30 relative to the frame 10 by engaging with the stopper 36a of the lower corner member 36. As shown in Figures 18 to 20, the lower anti-detachment component 50 of this embodiment has a lower base (base) 51, a support cover portion 52, two lower insertion portions (insertion portions) 53, and two lower bulging portions (bulging portions) 54, and is integrally molded from resin. The lower base 51 is a flat plate with a rectangular shape that is longitudinal along the vertical axis. The upper edge of the lower base 51, located on the indoor side, has a square-shaped engagement notch 51a. The engagement notch 51a is sized to allow the tip of the stopper 36a provided on the lower corner member 36 to be inserted, and opens on the edge of the lower base 51 located on the indoor side. The support cover portion 52 extends in the visible direction from the edge located on the indoor side of the lower base 51 toward the inner circumference, and is provided at a position that constitutes the lower half of the lower base 51. The upper end of the support cover portion 52 is provided with a support surface portion 52a that can be contacted by the lower surface of the lower corner member 36. The lower insertion portion 53 is a flat plate shape that protrudes outward from a position approximately in the center in the height direction on the outer peripheral surface (reference surface) 51b of the lower base 51, extends along the visible direction, and is arranged side by side in the depth direction. The protrusion dimension of the lower insertion portion 53 from the outer peripheral surface 51b of the lower base 51 is set to be greater than the plate thickness of the second vertical flat plate portion 13Bg that constitutes the second depth surface 13Bf of the second vertical frame 13B. The lower bulge portion 54 protrudes in directions away from each other from the protruding end of each lower insertion portion 53. The total width of the two lower bulges 54 is smaller than that of the lower base 51. Each lower bulge 54 constitutes a lower opposing surface 55. The lower opposing surface 55 faces the outer peripheral surface 51b of the lower base 51 and has a first lower opposing surface portion (first clamping portion) 55a, a lower guide surface portion (guide surface) 55b, a second lower opposing surface portion (second clamping portion) 55c, and a lower introduction surface portion 55d. The first lower opposing surface portion 55a and the second lower opposing surface portion 55c are planes that are aligned with the outer peripheral surface 51b of the lower base 51, and the lower guide surface portion 55b is a plane that is inclined to be continuous between the first lower opposing surface portion 55a and the second lower opposing surface portion 55c.The lower introduction surface portion 55d is a plane continuous with the end of the second lower opposing surface portion 55c, and is inclined so as it moves away from the second lower opposing surface portion 55c, it gradually becomes more peripheral. The distance between the first lower opposing surface portion 55a and the peripheral surface 51b of the lower base 51 is set such that the first vertical flat plate portion 13Ag, which constitutes the first visible surface 13Af in the first vertical frame 13A, can be inserted through it, but the second vertical flat plate portion 13Bg of the second vertical frame 13B cannot be inserted through it. The distance between the second lower opposing surface portion 55c and the peripheral surface 51b of the lower base 51 is set such that the second vertical flat plate portion 13Bg of the second vertical frame 13B can be inserted through it. To give specific numerical examples, the distance between the first lower opposing surface 55a and the outer peripheral surface 51b of the lower base 51 is configured to be 2.1 mm, and the distance between the second lower opposing surface 55c and the outer peripheral surface 51b of the lower base 51 is configured to be 2.7 mm. These lower opposing surfaces 55 are provided such that the lower introduction surface 55d is on the lower side.

[0030] As shown in Figure 21(a), the first vertical frame 13A to which the aforementioned lower detachment prevention part 50 is attached is provided with a first vertical mounting groove (mounting groove) 3Aa and a first vertical insertion hole (insertion hole) 3Ab in the first vertical flat plate portion 13Ag which constitutes the first visible surface 13Af of the first door stop wall portion 13Ab. The first vertical mounting groove 3Aa is a through hole with a width that allows the lower insertion portion 53 of the lower detachment prevention part 50 to be inserted, but prevents the two lower bulging portions 54 from being inserted, and is formed to be an elongated hole along the longitudinal side of the first vertical frame 13A. This first vertical mounting groove 3Aa extends upward with its closed end face aligned at a distance d5 from the first visible surface (positioning contact surface) 12Af of the first door stop wall portion 12Ab provided on the first lower frame 12A. This distance d5 is the position in which, when the lower insertion portion 53 of the lower anti-detachment component 50 is placed in the first vertical mounting groove 3Aa, the lower end surface (restricting portion) 51c of the lower base 51 abuts against the first visible surface 12Af, and the stopper 36a of the lower corner member 36 provided on the fixed screen door 30 can be inserted into the engagement notch 51a. The first vertical insertion hole 3Ab is a through hole having a width and length through which the two lower bulging portions 54 of the lower anti-detachment component 50 can be inserted, but through which the lower base 51 cannot be inserted, and is formed in a portion above the first vertical mounting groove 3Aa. The first vertical mounting groove 3Aa and the first vertical insertion hole 3Ab are in communication with each other. The distance d6 from the closed end face of the first vertical mounting groove 3Aa to the first vertical insertion hole 3Ab is configured to be greater than the total length of the lower opposing surface 55 provided on the lower anti-detachment component 50, that is, the sum of the dimensions of the lower introduction surface portion 55d, the second lower opposing surface portion 55c, the lower guide surface portion 55b, and the first lower opposing surface portion 55a.

[0031] On the other hand, the second vertical frame 13B to which the lower anti-detachment component 50 is attached is provided with a second vertical mounting groove (mounting groove) 3Ba and a second vertical insertion hole (insertion hole) 3Bb in the second vertical flat plate portion 13Bg which constitutes the second visible surface 13Bf of the second door stop wall portion 13Bb, as shown in Figure 21(b). The second vertical mounting groove 3Ba is a through hole with a width that allows the lower insertion portion 53 of the lower anti-detachment component 50 to be inserted, but prevents the two lower bulging portions 54 from being inserted, and is formed along the longitudinal side of the second vertical frame 13B. This second vertical mounting groove 3Ba extends upward with its closed end face aligned at a distance d5 from the second visible surface (positioning contact surface) 12Bf of the second door stop wall portion 12Bb provided on the second lower frame 12B. The second vertical insertion hole 3Bb is a through hole having a width and length that allows the two lower bulges 54 of the lower anti-detachment component 50 to be inserted, but prevents the lower base 51 from being inserted, and is formed in a portion above the second vertical mounting groove 3Ba. The second vertical mounting groove 3Ba and the second vertical insertion hole 3Bb are in communication with each other. The distance d7 from the closed end face of the second vertical mounting groove 3Ba to the second vertical insertion hole 3Bb is configured to match the sum of the dimensions of the lower introduction surface portion 55d and the second lower opposing surface portion 55c provided on the lower anti-detachment component 50. In other words, the second vertical mounting groove 3Ba provided in the second vertical frame 13B is configured such that the position from the second visible surface 12Bf of the second lower frame 12B to the closed end surface coincides with the position from the first visible surface 12Af of the first lower frame 12A to the closed end surface in the first vertical mounting groove 3Aa provided in the first vertical frame 13A, while the distance d7 from the closed end surface to the second vertical insertion hole 3Bb is shorter than the distance d6 from the closed end surface to the first vertical insertion hole 3Ab of the first vertical mounting groove 3Aa.

[0032] In other words, in the second vertical frame 13B, the distance d7 along the longitudinal side of the portions located on both sides of the second vertical mounting groove 3Ba (the clamped portions, hereinafter referred to as the second vertical clamped portions 3Bc) is set to be approximately equal to the sum of the dimensions of the lower introduction surface portion 55d and the second lower opposing surface portion 55c provided on the lower anti-detachment component 50. In contrast, in the first vertical frame 13A, the distance d6 along the longitudinal side of the portions located on both sides of the first vertical mounting groove 3Aa (the clamped portions, hereinafter referred to as the first vertical clamped portions 3Ac) is set to be larger than the sum of the dimensions of the lower introduction surface portion 55d, the second lower opposing surface portion 55c, the lower guide surface portion 55b, and the first lower opposing surface portion 55a provided on the lower anti-detachment component 50.

[0033] Therefore, when attaching the lower anti-detachment component 50 to the first vertical frame 13A, as shown in Figure 22(a), if the first vertical clamping portion 3Ac is inserted from the lower introduction surface portion 55d between the lower base 51 and the lower opposing surface 55 and the lower insertion portion 53 is positioned in the first vertical mounting groove 3Aa, the first vertical clamping portion 3Ac will be positioned between the outer peripheral surface 51b of the lower base 51 and the first lower opposing surface portion 55a, thereby preventing the lower anti-detachment component 50 from moving along the facing direction relative to the first vertical frame 13A. Furthermore, when the lower insertion portion 53 is positioned in the first vertical mounting groove 3Aa, the lower end surface 51c of the lower base 51 will be in contact with the first facing surface 12Af of the first lower frame 12A, thus preventing the lower anti-detachment component 50 from moving along the facing direction relative to the first vertical frame 13A.

[0034] Similarly, when attaching the lower anti-detachment component 50 to the second vertical frame 13B, as shown in Figure 22(b), by inserting the second vertical clamping portion 3Bc from the lower introduction surface portion 55d between the lower base 51 and the lower opposing surface 55 and positioning the lower insertion portion 53 in the second vertical mounting groove 3Ba, the second vertical clamping portion 3Bc will be positioned between the outer peripheral surface 51b of the lower base 51 and the second lower opposing surface portion 55c, thereby preventing the lower anti-detachment component 50 from moving along the viewing direction relative to the second vertical frame 13B. Furthermore, when the lower insertion portion 53 is positioned in the second vertical mounting groove 3Ba, the lower end surface 51c of the lower base 51 will be in contact with the second viewing surface 12Bf of the second lower frame 12B, thus preventing the lower anti-detachment component 50 from moving along the viewing direction relative to the second vertical frame 13B.

[0035] As described above, when the lower anti-detachment component 50 is attached to the first vertical frame 13A, the lower end surface 51c of the lower base 51 abuts against the first visible surface 12Af of the first lower frame 12A, and when the lower anti-detachment component 50 is attached to the second vertical frame 13B, the lower end surface 51c of the lower base 51 abuts against the second visible surface 12Bf of the second lower frame 12B. Therefore, if fixed screen doors 30 of the same shape are arranged, the stopper 36a of the lower corner member 36 can be inserted into the engagement notch 51a of the lower anti-detachment component 50 in either the first frame body 10A or the second frame body 10B.

[0036] As explained above, the upper anti-detachment component 40 is provided with a first upper opposing surface portion 47a and a second upper opposing surface portion 47c, which are at different distances from the outer peripheral surface 41a of the upper base 41. Therefore, it can be used in common with the first upper frame 11A and the second upper frame 11B, which have different plate thicknesses. Similarly, the lower anti-detachment component 50 is provided with a first lower opposing surface portion 55a and a second lower opposing surface portion 55c, which are at different distances from the outer peripheral surface 51b of the lower base 51. Therefore, it can be used in common with the first vertical frame 13A and the second vertical frame 13B, which have different plate thicknesses.

[0037] Furthermore, in the first upper frame 11A, the closed end face of the first upper mounting groove 2Aa, where the upper insertion portion 43 is located, is formed at a distance d1 from the first visible surface 13Af of the first vertical frame 13A, and its extension length is set to a distance d3 corresponding to the first upper clamped portion 2Ac. On the other hand, in the second upper frame 11B, the closed end face of the second upper mounting groove 2Ba, where the upper insertion portion 43 is located, is formed at a distance d1 from the second visible surface 13Bf of the second vertical frame 13B, and its extension length is set to a distance d4 corresponding to the second upper clamped portion 2Bc. Therefore, it is possible to attach the upper detachment prevention component 40 to a position common to both the first upper frame 11A and the second upper frame 11B. Similarly, in the first vertical frame 13A, the extension length of the first lower mounting groove where the lower insertion portion 53 is located is set to a distance d6 corresponding to the first vertical clamped portion 3Ac, and the closed end face of the first lower mounting groove is positioned so that the lower base 51 abuts against the first visible surface 12Af of the first lower frame 12A. On the other hand, in the second vertical frame 13B, the extension length of the second vertical mounting groove 3Ba where the lower insertion portion 53 is located is set to a distance d7 corresponding to the second vertical clamped portion 3Bc, and the closed end face of the second vertical mounting groove 3Ba is positioned so that the lower base 51 abuts against the second visible surface 12Bf of the second lower frame 12B. Therefore, the lower detachment prevention component 50 can be attached to a position common to both the first vertical frame 13A and the second vertical frame 13B. Therefore, if the same fixed screen door 30 is placed in the first frame 10A and the second frame 10B, the upper insertion projections 42 of each can be inserted into the locking holes 35a of the upper corner member 35, and the stopper 36a of the lower corner member 36 can be inserted into the engagement notch 51a.

[0038] In the embodiments described above, a component for preventing a fixed screen door from coming off a frame is illustrated, but the present invention is not necessarily limited to this, and can be applied to other components for building fixtures. In this case, the component that is common to profiles with different plate thicknesses does not necessarily need to be located in the same position. Also, the profile to which the component is attached does not need to be molded from resin. Furthermore, although two clamping portions are provided in the bulging portion at different distances from the reference surface, it is also possible to configure it to provide three or more clamping portions at different distances from the reference surface. Moreover, although a clamping portion that is planar is illustrated, it does not necessarily have to be planar, and it may have any other shape as long as the part to be clamped is positioned between it and the reference surface.

[0039] As described above, the joinery component according to the present invention comprises a base having a reference surface, an insertion portion protruding from the reference surface, and a bulging portion protruding outward from the insertion portion, wherein the base is positioned on one surface side and the bulging portion is positioned on the other surface side of a profile provided with a mounting groove, and the insertion portion is moved along the mounting groove so that the clamped portions of the profile located on both sides of the mounting groove are positioned between the reference surface and the bulging portion, wherein the bulging portion is provided with a first clamping portion set at a first distance from the reference surface, and a second clamping portion set at a second distance greater than the first distance from the reference surface. According to this invention, since a first clamping portion and a second clamping portion are provided between the reference surface and the bulging portion at different distances from each other, it becomes possible to share building component parts even for profiles with different plate thicknesses.

[0040] Furthermore, the joinery component according to the present invention is a joinery component that is mounted on a profile having a mounting groove with one end being an open end, and an insertion hole that is continuous with the mounting groove via the open end and has a wider opening than the mounting groove, and comprises a base having a reference surface, an insertion portion protruding from the reference surface, and a bulging portion protruding outward from the insertion portion, wherein the bulging portion and the insertion portion are inserted into the insertion hole, and from this state the insertion portion is inserted into the mounting groove, thereby positioning the clamped portions of the profile located on both sides of the mounting groove between the reference surface and the bulging portion, wherein the bulging portion is provided with a first clamping portion set at a first distance from the reference surface, and a second clamping portion set at a second distance greater than the first distance from the reference surface. According to this invention, since a first clamping portion and a second clamping portion are provided between the reference surface and the bulging portion at different distances from each other, it becomes possible to share building component parts even for profiles with different plate thicknesses.

[0041] Furthermore, the present invention is characterized in that, in the above-described building component, the base is provided with a limiting portion which is positioned inside the insertion hole when the clamped portion is positioned between the reference surface and the bulging portion, and which faces the opening circumferential surface of the insertion hole, thereby restricting the movement of the base relative to the profile in the direction along the reference surface. According to this invention, the limiting portion can prevent misalignment of the joinery components relative to the profile.

[0042] Furthermore, the present invention is characterized in that, in the above-described building component, the restricting portion intersects with respect to a first direction in which the clamped portion deviates from the mounting groove, and restricts movement in a second direction along the reference plane. According to this invention, the limiting portion can prevent the door and window components from shifting laterally.

[0043] Furthermore, the present invention is characterized in that, in the above-described building component, a guide surface is provided between the first clamping portion and the second clamping portion to connect the first clamping portion and the second clamping portion. According to this invention, the guide surface facilitates the movement of the part to be clamped from the second clamping portion to the first clamping portion.

[0044] Furthermore, the mounting structure for joinery parts according to the present invention is a mounting structure for joinery parts for attaching common joinery parts to a first profile and a second profile having a greater plate thickness than the first profile, wherein each of the first profile and the second profile is provided with a mounting groove and an insertion hole that is continuous with the open end of the mounting groove and has a wider opening than the mounting groove, the joinery part comprises a base having a reference surface, an insertion portion protruding from the reference surface and a bulging portion protruding outward from the insertion portion, the bulging portion is provided with a first clamping portion and a second clamping portion which are at different distances from the reference surface, and the first clamping portion is provided with the base The distance from the reference surface is set to a dimension that allows the first profile to be placed but prevents the second profile from being placed, the distance of the second clamping portion from the reference surface is set to a dimension that allows the second profile to be placed, the mounting groove provided in the first profile is formed such that the distance from the closed end face to the insertion hole is longer than the distance from the closed end face to the insertion hole of the mounting groove provided in the second profile, and after inserting the bulging portion and the insertion portion into the insertion hole, the clamped portions located on both sides of the mounting groove are inserted from between the reference surface and the second clamping portion, and the insertion portion is inserted into the mounting groove. According to this invention, since a first clamping portion and a second clamping portion are provided between the reference surface and the bulging portion at different distances from each other, it becomes possible to share building component parts even for profiles with different plate thicknesses.

[0045] Furthermore, the present invention is characterized in that, in the above-described mounting structure for building components, the building component is provided with a limiting portion that faces the closed end face of the insertion hole when the clamped portion is positioned between the reference surface and the bulging portion, and the dimensions from the closed end face of the insertion hole to the closed end face of the mounting groove are the same for both the first profile and the second profile. According to this invention, by positioning the limiting portion opposite the closed end face of the insertion hole, it becomes possible to attach building components to profiles with different plate thicknesses in the same position using the closed end face as a reference.

[0046] Furthermore, the mounting structure for joinery parts according to the present invention is a mounting structure for joinery parts that attaches a common joinery part to a first profile and a second profile having a greater plate thickness than the first profile, wherein each of the first profile and the second profile is provided with a mounting groove having an open end, the joinery part comprises a base having a reference surface, an insertion portion protruding from the reference surface, and a bulging portion protruding outward from the insertion portion, the bulging portion is provided with a first clamping portion and a second clamping portion having different distances from the reference surface, and the first clamping portion is provided with the reference The distance from the surface is set to a dimension that allows the first profile to be placed but prevents the second profile from being placed, the distance of the second clamping portion from the reference surface is set to a dimension that allows the second profile to be placed, the mounting groove provided in the first profile is formed such that the distance from the closed end face to the open end is longer than the distance from the closed end face to the open end of the mounting groove provided in the second profile, the clamped portions located on both sides of the mounting groove are inserted from between the reference surface and the second clamping portion, and the insertion portion is inserted into the mounting groove. According to this invention, since a first clamping portion and a second clamping portion are provided between the reference surface and the bulging portion at different distances from each other, it becomes possible to share building component parts even for profiles with different plate thicknesses.

[0047] Furthermore, in the above-described mounting structure for building components, the present invention provides a positioning contact surface for each of the first and second profiles that contacts the building component when the clamped portion is positioned between the reference surface and the bulging portion, and the dimensions from the positioning contact surface to the closed end face of the mounting groove are the same for both the first and second profiles. According to this invention, by bringing the joinery parts into contact with the positioning contact surface, it becomes possible to attach the joinery parts to the same position using the positioning contact surface as a reference, even for profiles with different plate thicknesses.
