  Hereinafter, preferred embodiments of a fitting according to the present invention will be described in detail with reference to the accompanying drawings.

  1 to 4 show a joinery that is an embodiment of the present invention. As shown in FIGS. 3 and 4, the joinery illustrated here includes an opening frame 10 and a glass window (movable shoji) 20, and is operated with respect to the opening frame 10 by operating an operator handle 30 provided on the opening frame 10. The glass window 20 is configured to be openable and closable. The opening frame 10 is configured by a four-round framework of an upper frame 11, a lower frame 12, and left and right vertical frames 13. The glass window 20 is configured by attaching an upper window ridge 22, a lower window ridge 23, and left and right window ridges 24 around a rectangular glass plate 21.

  The frames 11, 12, and 13 constituting the opening frame 10 are extruded shapes formed by resin, and are configured to have the same cross-sectional shape. As shown in FIGS. 1 and 2, each of the frames 11, 12, and 13 is formed so that both end surfaces are inclined at 45 °, and the opening frame 10 is formed by joining these inclined surfaces to each other. Is configured. The end surfaces of the frames 11, 12, and 13 are joined to each other by, for example, heat welding. As apparent from FIGS. 3 and 4, the frames 11, 12, and 13 applied in the present embodiment are provided with ridges 11 a, 12 a, and 13 a at the edges located on the indoor side in the prospective surface. is there. The protrusions 11a, 12a, and 13a are protrusions that have a small width dimension along the prospective direction and a small amount of protrusion from the prospective surface, and project from the entire length of the frames 11, 12, and 13 along the longitudinal direction. ing.

  Although not shown in the drawing, the window rods 22, 23, and 24 constituting the glass window 20 are extruded shapes formed of resin, respectively, like the frames 11, 12, and 13 of the opening frame 10. The end surfaces having a cross-sectional shape and inclined at 45 ° are joined to each other by heat welding.

  As shown in FIG. 3, vertical sliding windows are provided between the opening frame 10 and the glass window 20 between the upper frame 11 and the upper window ridge 22 and between the lower frame 12 and the lower window ridge 23, respectively. A support link mechanism 25 for configuring is provided. That is, the support link mechanism 25 has a window shaft (hereinafter referred to as “window door”) positioned on the right side with respect to the longitudinal direction of the window shaft (hereinafter referred to as “window door bottom wall 24”) positioned on the left side in FIG. The glass window 20 is supported with respect to the opening frame 10 so that the front edge 24 can be rotated and the window door bottom edge 24 can slide to the left and right along the upper frame 11 and the lower frame 12. .

  According to this support link mechanism 25, when the window door rod 24 is arranged so as to overlap the vertical frame 13 located on the left side of the opening frame 10 in FIG. 4, the four rounds of the window rods 22, 23, 24 are opened. The opening frame 10 can be closed by bringing it into contact with the frame 10. From this state, the glass window 20 is rotated so that the window door ridge 24 protrudes outward from the window door ridge 24 and the window door ridge 24 is slid to the right. As indicated by a two-dot chain line, the glass window 20 protrudes toward the outdoor side along the prospective direction, and the opening frame 10 can be opened. If the glass window 20 is rotated so that the window door toe 24 moves toward the indoor side from the state in which the opening frame 10 is opened, and the window door bottom wall 24 is slid to the left, the opening frame 10 is again moved. It can be returned to the closed state.

  When the operator handle 30 is rotated, the operator handle 30 operates an opening / closing mechanism 31 provided between the glass window 20 and the lower window rod 23 to increase or decrease the distance between the window door rod 24 of the glass window 20 and the opening frame 10. Is. The operator handle 30 according to the present embodiment is attached to the attachment member 40 so as to protrude from the finding surface facing the room side of the attachment member 40 provided on the lower frame 12. As shown in FIG. 5, the attachment member 40 extends between the lower end portions of the left and right vertical frames 13 along the longitudinal direction of the lower frame 12, and is provided on the prospective surfaces of the left and right vertical frames 13 facing each other. The length is shorter than the mutual interval. In the present embodiment, the length of the mounting member 40 is set so that, for example, a gap of 1.5 to 2.0 mm is provided between both ends of the mounting member 40 and each vertical frame 13.

  The reason why the dimension along the longitudinal direction of the mounting member 40 is shorter than the mutual distance between the prospective surfaces of the vertical frame 13 is that manufacturing errors and assembly errors are caused between the vertical frame 13 and the end of the mounting member 40. This is to ensure a gap to be absorbed. Further, by moving the operator handle 30 attached to the attachment member 40 along the left-right direction, alignment and adjustment with the opening / closing mechanism 31 provided between the glass window 20 and the lower window rod 23 are easily performed. Because. Moreover, if the dimension along the longitudinal direction of the mounting member 40 is configured to be shorter than the distance between the prospective surfaces of the vertical frame 13, when the opening frame 10 formed of resin or a cover plate 43 described later is hot-extended. However, mutual interference can be prevented in advance. As shown in FIG. 3, in the present embodiment, the attachment member 40 includes the reference plate 41, the reinforcing plate 42, and the cover plate 43.

  The reference plate 41 includes a reference base portion (base portion) 41a, a reference mounting wall portion 41b, and a reference cover wall portion 41c, and is integrally formed of a metal such as aluminum or an aluminum alloy. The reference base portion 41 a is a plate-like portion that is disposed to face the upper surface of the lower frame 12, and has two support ribs 41 d at a portion that faces the upper surface of the lower frame 12. The support rib 41d is set so that the protrusion amount of the support rib 41d is larger than that of the support rib 41d. When the reference base portion 41a is disposed on the upper surface of the lower frame 12 via the support ribs 41d, the reference base portion 41a is inclined so that the distance from the upper surface of the lower frame 12 gradually increases toward the indoor side. Will do. The reference mounting wall portion 41b is a plate-like portion extending vertically upward from an edge portion located on the indoor side of the reference base portion 41a when the reference base portion 41a is disposed on the upper surface of the lower frame 12. The reference cover wall portion 41c is a plate-like portion that bends and extends substantially horizontally from the upper end portion of the reference mounting wall portion 41b toward the outdoor side.

  The reinforcing plate 42 is used to reinforce the reference plate 41 and is formed of a material having rigidity greater than that of the reference plate 41, such as a steel material having a thickness greater than that of the reference plate 41. The reinforcing plate 42 is integrally provided with a lower reinforcing portion 42a that is overlaid on the upper surface of the reference base portion 41a and an upper reinforcing portion 42b that is overlaid on the finding surface that faces the outdoor side of the reference mounting wall portion 41b.

  The cover plate 43 is for covering the outer surface of the reference plate 41 and is formed of resin. The cover plate 43 is integrally provided with a side cover portion 43a, an upper cover portion 43b, and a lower engagement fin portion 43c. The side cover portion 43a covers the finding surface facing the indoor side of the reference mounting wall portion 41b, and the upper cover portion 43b covers the upper surface of the reference cover wall portion 41c. The lower engaging fin portion 43c protrudes upward from the edge located on the indoor side in the prospective surface of the upper cover portion 43b, and extends upward along the direction of finding from the portion extending over the entire length along the longitudinal direction of the cover plate 43. Protruding.

  The attachment member 40 having the above-described configuration is configured so that the reference base portion 41a of the reference plate 41 is placed in a state where the outer surface of the side cover portion 43a is located on the outer side of the protrusion 12a of the lower frame 12 in the cover plate 43. And a screw (not shown) is screwed into the lower frame 12 via the lower reinforcing portion 42a of the reinforcing plate 42 and the reference base portion 41a of the reference plate 41. 12 is fixed. A screw (not shown) screwed into the lower frame 12 reaches the steel lower frame reinforcing member 12A provided at the tip portion inside the hollow of the lower frame 12, and the reinforcing plate 42 of the mounting member 40 and the lower frame The reinforcing material 12A is connected. The operator handle 30 is screwed into the side cover portion 43a of the cover plate 43, the reference mounting wall portion 41b of the reference plate 41, and the upper reinforcing portion 42b of the reinforcing plate 42 through the handle base 32, The lower frame 12 is connected to the lower frame reinforcement member 12 </ b> A via the attachment member 40.

  As described above, the attachment member 40 to be attached to the operator handle 30 is attached to the lower frame 12 in a state where the finding surface facing the indoor side is on the outdoor side of the protruding portion 12a of the lower frame 12. . Therefore, it becomes possible to attach the operator handle 30 without enlarging the lower frame 12, and even when the opening frame 10 is made of resin, the design of the joinery is not impaired at all. When the glass window 20 is opened and closed, the operator handle 30 may be operated, so that the opening and closing operation can be easily performed.

  On the other hand, the left and right vertical frames 13 of the opening frame 10 are respectively provided with vertical frame components 50 at portions corresponding to both ends of the mounting member 40. As shown in FIGS. 6A and 6B, the vertical frame component 50 is bent from the surface at the engagement plate portion 51 that forms a rectangular flat plate shape and the edge portion of the engagement plate portion 51. The holding piece portion 52 and the supporting cover portion 53 that are present, and a hook portion 54 provided on the back surface of the engaging plate portion 51 are formed integrally with resin. As shown in FIG. 7C, the engagement plate portion 51 is configured to have a length that protrudes higher than the attachment member 40 when the lower end surface is in contact with the prospective surface of the lower frame 12. For example, the plate thickness of the engaging plate portion 51 is substantially the same as the protruding height of the ridge portion 13 a protruding from the prospective surface of the vertical frame 13. As shown in FIG. 6A and FIG. 7B, the sandwiching piece portion 52 is a portion that is bent and extends from a portion that becomes the lower edge on the surface of the engagement plate portion 51, and is substantially at the center of the lower edge. It is provided in the part which becomes. The support cover portion 53 is a thin plate-like portion that extends from a portion serving as one side edge of the engagement plate portion 51 in a direction substantially perpendicular to the same direction as the sandwiching piece portion 52, and the mounting member 40 and the vertical frame 13. It is comprised so that it may have a larger width dimension than the clearance gap between. As shown in FIGS. 5, 7-2, 7-3, and 7-5, the support cover portion 53, when the lower end surface of the engagement plate portion 51 is in contact with the prospective surface of the lower frame 12, It is provided from the lower end of the engaging plate portion 51 to a position protruding upward beyond the upper surface of the mounting member 40. The hook portion 54 is a flat plate-like portion that protrudes at a substantially right angle along the horizontal direction from a substantially central portion on the back surface of the engagement plate portion 51. The hook portion 54 is configured such that the hook base portion 54a serving as a connecting portion with the engaging plate portion 51 is narrow and the protruding end portion 54b is wide.

  The vertical frame component 50 is attached to the vertical frame 13 in advance by the following procedure before attaching the attachment member 40 to the lower frame 12. That is, first, the hook plate 54 is inserted into the hook hole 13 </ b> A formed on the prospective surface of the vertical frame 13, and the rear surface of the engagement plate portion 51 is brought into contact with the prospective surface of the vertical frame 13. The lower end surface is brought into contact with the prospective surface of the lower frame 12. As shown in FIG. 7A, the hook hole 13 </ b> A of the vertical frame 13 has a width that allows the upper half portion 13 </ b> Aa to be inserted through the protruding end portion 54 b of the hook portion 54, and the lower half portion 13 </ b> Ab is the hook portion 54. The hook base portion 54a is formed so as to have a width that allows the protruding end portion 54b to not be inserted. Accordingly, after the protruding end portion 54b of the hook portion 54 is inserted into the upper half portion 13Aa of the hook hole 13A, the vertical frame component 50 is moved downward so that the hook base portion 54a is positioned at the lower half portion 13Ab of the hook hole 13A. Then, the protruding end portion 54b of the hook portion 54 is locked to the back surface of the vertical frame 13, and the movement of the vertical frame 13 away from the prospective surface and the movement in the left-right direction along the prospective surface are restricted. Become.

  After the vertical frame component 50 is locked to the left and right vertical frames 13, if the attachment member 40 is attached to the upper surface of the lower frame 12, the sandwiching piece portion 52 protruding from the engagement plate portion 51 becomes the upper surface of the lower frame 12. Since it is sandwiched between the reference base 41a of the reference plate 41, the vertical frame component 50 is prevented from moving upward with respect to the vertical frame 13. Therefore, it is possible to attach the vertical frame component 50 to the vertical frame 13 without requiring components such as screws.

  When the attachment member 40 is attached to the lower frame 12 with the vertical frame part 50 being engaged with the vertical frame 13, the opening frame 10 is laid flat with the surface on the indoor side facing downward, whereby the attachment member 40 mounting operations can be facilitated. In other words, in a state where the vertical frame component 50 is locked to the vertical frame 13, the support cover portions 53 of the vertical frame component 50 are in a state of protruding toward the inner peripheral side. As described above, even when the vertical frame part 50 is locked to the vertical frame 13, the vertical frame part 50 is restricted from moving away from the prospective surface of the vertical frame 13 and moving in the left-right direction along the prospective surface. Therefore, even if the mounting member 40 is configured to have a length shorter than the distance between the prospective surfaces of the left and right vertical frames 13 facing each other, the both ends of the mounting member 40 are mounted on the support cover portion 53. Both hands can be released from the member 40, and the screwing operation of the screw can be facilitated. Further, after the attachment member 40 is attached to the lower frame 12, the support cover portion 53 of the vertical frame component 50 is in a state of covering the finding surface facing the indoor side of the attachment member 40. Accordingly, there is no possibility that external light leaks from the gap between the vertical frame 13 and the mounting member 40 and enters the room.

  As shown in FIG. 3 to FIG. 5, in the joinery to which the attachment member 40 is attached, the indoor opening frame 10 </ b> A is provided at a portion that is on the indoor side of the glass window 20 by the attachment member 40, the upper frame 11, and the left and right vertical frames 13.

The fixed screen 60 is configured by stretching a sheet-like net 64 inside a fixed upper rod 61, a fixed lower rod 62, and left and right fixed vertical rods 63 that are assembled around four sides.

  Each of the fixing rods 61, 62, 63 constituting the fixed screen 60 is an extruded shape member formed of a metal such as aluminum or aluminum alloy. The fixed upper rod 61 and the left and right fixed vertical rods 63 are configured to have the same cross-sectional shape. Specifically, as shown in FIGS. 3 and 4, the flange bases 61a and 63a having a hollow rectangular tube shape, and the outer peripheral side of the fixed rods 61 and 63 from the finding surface facing the indoor side of the flange bases 61a and 63a. A fixed upper rod 61 and left and right fixed vertical rods 63 are configured with cover fin portions 61b and 63b extending toward the front. On the other hand, the fixed lower collar 62 has a deformed hollow shape in which the prospective dimension of the part on the outer peripheral side is smaller than the part on the inner peripheral side. An engagement groove 62a having a width capable of accommodating the lower engagement fin portion 43c of the attachment member 40 is formed in the prospective surface on the outer peripheral side of the fixed lower collar 62 along the longitudinal direction. The hollow portion 62b on the inner peripheral side of the fixed lower rod 62 is configured to have substantially the same cross section as the flange base portion 63a of the fixed vertical rod 63. Beat fixing grooves 61c, 62c, and 63c are formed on the fixing surfaces 61, 62, and 63 that constitute the fixed screen 60 on the surface that faces the outdoor side. The beat mounting grooves 61c, 62c, and 63c are for press-fitting the peripheral edge of the net 64 together with the elastic beat 65 such as rubber.

  As shown in FIGS. 8A and 8B, the fixing rods 61, 62, and 63 are formed so that the respective end faces are orthogonal to the longitudinal direction, and the corner parts 70 are interposed between each other. Are joined together. As shown in FIGS. 9-1 to 9-5 and FIGS. 10-1 to 10-5, the corner component 70 has a square base plate 71 and two sides adjacent to the base plate 71 at right angles. It has an extended press-fit portion 72 and is integrally formed of resin.

  A corner mounting groove 73 is formed in a portion corresponding to the beat mounting grooves 61c, 62c, and 63c of the fixing rods 61, 62, and 63 on the surface that faces the outdoor side of the base plate 71. The corner mounting groove 73 has a relay groove portion 73a that extends linearly and two continuous groove portions 73b that are bent and extended from both ends of the relay groove portion 73a. The two continuous groove portions 73b are provided so as to be continuous with the beat mounting grooves 61c, 62c, 63c of the respective fixing rods 61, 62, 63 when the fixing rods 61, 62, 63 are joined by the corner part 70. Thus, the extension lines extend so as to intersect at approximately 90 °. The bending angles of the continuous groove portion 73b and the relay groove portion 73a are set so that the angle of entry is 135 °.

  According to the fixed screen door 60 in which the beat mounting grooves 61c, 62c, 63c of the fixing rods 61, 62, 63 are made continuous by the corner mounting groove 73 as described above, the net 64 is stretched on the fixing rods 61, 62, 63. The work at the time can be facilitated. That is, in the fixed screen 60, a net 64 having an outer dimension larger than that of the fixed rods 61, 62, 63 is prepared, and the four circumferences of the net 64 are press-fitted into the beat mounting grooves 61c, 62c, 63c and the corner mounting groove 73 together with the beat 65. By doing so, the net 64 is stretched on the fixing rods 61, 62, 63. The extra net 64 that protrudes to the outer peripheral side from the beat mounting grooves 61 c, 62 c, 63 c and the corner mounting groove 73 causes a cutting tool such as a cutter to travel along the beat mounting grooves 61 c, 62 c, 63 c and the corner mounting groove 73. I try to remove it. Here, when the corner mounting groove 73 of the corner part 70 is bent at an angle of 90 ° or less, the cutting tool cannot be accurately traveled along the corner mounting groove 73, and the net 64 may be cut. It becomes difficult. However, when the corner mounting groove 73 is configured to bend at an obtuse angle (135 °) as described above, it is also easy to accurately run the cutting tool along the corner mounting groove 73, and the protruding net 64 Can be reliably cut.

  The press-fit portions 72 of the corner parts 70 are each formed in an H shape having flanges 72b at both ends of the web 72a, and have outer dimensions that can be inserted with a gap in the hollow portions of the fixing rods 61, 62, and 63. It is formed. The extending end of the flange 72b is provided with a chamfered portion that serves as a guide when inserted into the hollow portions of the fixing rods 61, 62, and 63, respectively.

  The flange 72b of the press-fit portion 72 is provided with a positioning projection 74 and a crimping projection 75 that are paired with each other. The positioning projection 74 and the crimping projection 75 are projecting portions formed along the extending direction of the press-fit portion 72, and are formed corresponding to the surfaces of the flange 72b that are opposite to each other. The positioning protrusion 74 has a flat surface facing the inner surface of the fixing rods 61, 62, 63 when it is inserted into the hollow portions of the fixing rods 61, 62, 63 and is parallel to the inner surfaces of the fixing rods 61, 62, 63. (Hereinafter referred to as “positioning surface”). Each positioning protrusion 74 is provided continuously from the extending end of the press-fit portion 72 to a position beyond the majority of the press-fit portion 72. On the other hand, when the crimping protrusion 75 is inserted into the hollow portion of the fixing rod 61, 62, 63, the portion facing the inner surface of the fixing rod 61, 62, 63 is a semi-cylindrical outer peripheral surface (hereinafter referred to as “crimping portion”). ”). Each crimping protrusion 75 comes into contact with the inner surface of the fixing rod 61, 62, 63 at a later stage than the positioning projection 74 when the press-fit portion 72 is inserted into the hollow portion of the fixing rod 61, 62, 63. In addition, two are provided in the middle portion of the press-fit portion 72. The distance from the positioning surface of the positioning projection 74 to the crimping portion of the paired crimping projection 75 is slightly larger than the distance between the inner surfaces facing each other in the hollow portions of the fixing rods 61, 62, 63. It is set. A chamfered portion serving as an insertion guide to the hollow portion of the fixing rods 61, 62, and 63 is provided at a portion on the extending end side with respect to each of the positioning projection 74 and the crimping projection 75.

  When the corner component 70 configured as described above is inserted into the hollow portion of the fixing rod 61, 62, 63, only the positioning projection 74 having a flat positioning surface from the beginning of the insertion is the fixing rod 61, 62, 63. It will contact | abut to the inner surface. Accordingly, the press-fit portion 72 of the corner part 70 is sequentially inserted into the hollow portions of the fixing rods 61, 62, and 63 while being positioned by the positioning surface.

  As the insertion of the press-fit portion 72 into the hollow portion of the fixing rod 61, 62, 63 progresses, the crimping protrusion 75 eventually reaches the inner surface of the fixing rod 61, 62, 63. As described above, the distance from the positioning surface of the positioning projection 74 to the crimping portion of the paired crimping projection 75 is slightly larger than the distance between the inner surfaces of the hollow portions of the fixing rods 61, 62, 63. It is set as follows. For this reason, after the crimping protrusion 75 reaches the inner surface of the fixing rods 61, 62, 63, any one of the protrusions 74, 75 is deformed and the press-fitting portion 72 is brought into the hollow portion of the fixing rods 61, 62, 63. Will be inserted.

  Here, in this embodiment, the positioning surface of the positioning projection 74 is configured to be flat, while the crimping portion of the crimping projection 75 is configured to be the outer peripheral surface of the cylinder. Accordingly, the pressure acting on the crimping portion is larger than the pressure acting on the positioning surface, and the insertion of the press-fit portion 72 proceeds only when the crimping portion is deformed exclusively. That is, even after the press-fitting portion 72 reaches the inner surfaces of the fixing rods 61, 62, 63, the positioning surface of the positioning projection 74 continues to function as a guide as in the initial insertion, and the press-fitting portion 72 functions as the fixing rod 61. , 62, 63 are inserted into the hollow portions. As a result, the fixing rods 61, 62, 63 and the corner part 70 can be joined to each other in an accurately positioned state, in other words, the four-round fixing rods 61, 62, 63 can be accurately positioned. It becomes.

The entire length of the piece 80 extends from the upper end to the lower end. A chamfered portion serving as an insertion guide is provided at each of the protruding end portion of the insertion protrusion piece 80 and the lower end portion of the contact rib 82. The insertion protrusion piece 80 of the embodiment is provided with a contact rib 82 on the surface facing the base plate 71. The abutment rib 82 on the surface facing the base plate 71 is provided to share the left and right parts, and is not necessary when the left and right are configured as individual parts.

  As shown in (a) of FIG. 13, the insertion projecting piece 80 has a surface facing the outdoor side of the base plate 71 on the indoor side of the upper frame 11 when the fixed screen 60 is attached to the indoor opening frame 10 </ b> A. The abutment rib 82 is configured to abut against the pressing portion 76a of the pressing protrusion 76 in a state where it abuts the facing surface.

  The lower corner part 70L is for preventing the fixed screen door 60 attached to the indoor opening frame 10A from falling off in cooperation with the vertical frame part 50 provided on the vertical frame 13. 7-6 and FIGS. 10-1 to 10-5, the lower corner part 70L includes a stopper member 90 and an operation member 91.

  The stopper member 90 is disposed so as to be movable along the longitudinal direction of the fixed lower collar 62 in the accommodating portion 79 provided on the finding surface facing the outdoor side of the base plate 71. The accommodating portion 79 is opened only at a portion facing the prospective surface of the vertical frame 13 when the fixed screen 60 is attached to the indoor opening frame 10A. The stopper member 90 is disposed in the accommodating portion 79 with a protruding spring 92 interposed between the stopper member 90 and the inner end surface of the accommodating portion 79, and is urged in a direction in which it always protrudes by the urging force of the protruding spring 92. Is in a state of being

  The operation member 91 includes an operation portion 91a having a rectangular parallelepiped shape and a connection portion 91b protruding from the operation portion 91a.

The cutout groove 71 a of the base plate 71 through which the connecting portion 91 b passes is formed along the longitudinal direction of the fixed lower collar 62, and the operating member 91 can be moved in the longitudinal direction of the stationary lower collar 62 together with the stopper member 90. Is possible. The end surface of the notch groove 71a through which the connection portion 91b of the operation member 91 passes is brought into contact with the connection portion 91b when the stopper member 90 and the operation member 91 are moved with respect to the base plate 71. It has a function to specify.

  At the tip of the stopper member 90, a mounting guide surface 90a, a release guide surface 90b, and an erroneous mounting detection gap 90c are provided. The mounting guide surface 90a is a flat surface provided at a portion on the outdoor side of the stopper member 90, and is inclined so as to gradually protrude outward (to the left in FIG. 10-4) toward the base plate 71. The release guide surface 90b is a flat surface provided at a portion of the stopper member 90 on the indoor side, and is inclined so as to gradually recede inward (to the right in FIG. 10-4) toward the base plate 71. The erroneous mounting detection gap 90c is a flat surface extending from the innermost portion of the release guide surface 90b toward the base plate 71 at a substantially right angle, and the thickness of the protrusion 13a provided on the vertical frame 13 is The size is larger than that. The stopper member 90 is configured such that when the lower corner parts 70L are provided at both ends of the lower fixing rod 62, the respective mounting guide surfaces 90a face the finding surface of the vertical frame 13, and When moved into the accommodating portion 79 against the urging force of the spring 92, the distance between the projecting end faces is made smaller than the distance between the prospective faces of the vertical frame 13.

  As shown in FIGS. 7-3 and 14-1, the vertical frame component 50 attached to the prospective surface of the vertical frame 13 has a notch 55 at a portion of the engagement plate portion 51 facing the stopper member 90 of the lower corner component 70 </ b> L. And the installation surface 56 is provided. The cutout 55 of the vertical frame component 50 has a rectangular shape in which a portion located on the indoor side is opened, and is formed in a size that can accommodate the tip of the stopper member 90. In the cutout 55 of the vertical frame component 50, the end surface constituting the upper edge forms a stopper surface 55a. The stopper surface 55a is a flat surface extending in the horizontal direction and facing the lower side. As shown in FIG. 7-4, the stopper surface 55a is below the attachment member 40 in the engagement groove 62a provided in the fixed lower collar 62 of the fixed screen door 60. When the engagement fin portion 43 c is accommodated, it is formed so as to face the upper surface of the stopper member 90 slightly above the upper surface of the stopper member 90. The installation surface 56 is a plane parallel to the prospective surface secured above the notch 55 and has an area where the tip of the stopper member 90 can abut when the fixed screen door 60 is attached.

  In order to attach the fixed screen 60 configured as described above to the indoor opening frame 10A, first, the fixed screen 60 is set in an oblique posture so that the fixed upper rod 61 is close to the indoor opening frame 10A. From the state, the insertion protrusions 80 of the upper frame 11 are respectively inserted between the base plate 71 and the pressing protrusions 76 of the upper corner part 70U.

  At this time, since the positioning guide member 77 having the positioning guide surface 77a is provided in the upper corner part 70U, the position of the fixed screen 60 is displaced along the left-right direction with respect to the indoor opening frame 10A. The positional deviation of the fixed screen door 60 is corrected by the positioning guide surface 77a coming into contact with the vertical frame 13. Therefore, even when the upper end portion of the fixed screen 60 is roughly attached to the indoor opening frame 10A, the insertion protrusion piece 80 of the upper frame 11 is securely inserted into the base plate 71 and the pressing protrusion piece 76 of the upper corner part 70U. It will be possible to guide between. Moreover, as shown in FIG. 13B, when the pressing portion 76 a comes into contact with the contact rib 82 of the insertion protrusion piece 80, the pressing portion 76 a that enlarges the clearance with the base plate 71 is provided. Since it is elastically deformed, it is possible to easily perform the operation when inserting the insertion protrusion piece 80.

  After the insertion projecting piece 80 of the upper frame 11 is inserted between the base plate 71 and the pressing projecting piece 76 of the upper corner part 70U, the fixed lower collar 61 is maintained with the height position of the fixed upper collar 61 maintained. 62 is moved so as to be close to the indoor opening frame 10A, and the fixed screen 60 is set in a vertical posture. Meanwhile, as shown in FIG. 14A, the stopper member 90 provided on the lower corner part 70L has the mounting guide surfaces 90a abutting against the locating surface of the vertical frame 13 and resists the urging force of the protruding spring 92. In order to retreat, it will be in the state which got over the protrusion 13a of the vertical frame 13, and contact | abutted to the installation surface 56 above the notch 55 of the vertical frame component 50. FIG.

  Finally, if the fixed screen 60 is moved downward with respect to the indoor opening frame 10A and the lower engagement fin portion 43c of the mounting member 40 is accommodated in the engagement groove 62a of the fixed lower rod 62, the indoor opening frame The fixed screen 60 can be attached to 10A. In this state, as shown in FIG. 14B, when the stopper member 90 faces the notch 55 of the vertical frame component 50, the leading end of the stopper member 90 is formed in the notch groove 71a by the urging force of the protruding spring 92. It protrudes inside, and its upper surface is at a position facing the stopper surface 55a. Therefore, even when an external force that moves the fixed screen 60 upward is applied to the indoor opening frame 10A, the upper surface of the stopper member 90 abuts against the stopper surface 55a, so that the fixed screen 60 opens to the indoor opening. It does not move upward relative to the frame 10A. As a result, it is possible to prevent the fixed screen 60 from being inadvertently dropped from the indoor opening frame 10A.

  Further, in the fixed screen 60 attached to the indoor opening frame 10A as described above, the pressing portion 76a always faces the indoor side of the upper frame 11 relatively via the contact rib 82 of the insertion protrusion piece 80. It functions so that the finding surface comes into contact with the finding surface facing the outdoor side of the base plate 71. Therefore, there is no possibility of causing a situation in which the fixed screen 60 attached to the indoor opening frame 10A is loose. Further, when a large external force is applied to the fixed screen 60 and the locating surface of the base plate 71 is separated from the locating surface of the fixed upper collar 61, the support surface 80 a of the insertion protrusion piece 80 and the support portion of the pressing protrusion piece 76. 76b abut against each other. Therefore, the pressing portion 76a does not deform beyond the elastic limit, and there is no possibility that the fixed screen 60 will be loose or fall off due to damage to the pressing portion 76a. When the external force applied to the fixed screen 60 is removed, the finding surface that faces the indoor side of the upper frame 11 again comes into contact with the finding surface that faces the outdoor side of the base plate 71 by the elastic restoring force of the pressing portion 76a. Therefore, the situation that the fixed screen 60 is rattled is prevented.

  When the stopper member 90 is disposed in the notch 55 of the vertical frame part 50 without the insertion protrusion part 80 of the upper frame 11 being inserted between the base plate 71 and the pressing protrusion part 76 of the upper corner part 70U. In the (erroneous mounting), since the upper end part of the fixed screen door 60 which is not restrained moves toward the indoor side, the fixed screen door 60 is inclined with respect to the indoor side opening frame 10A. In particular, in the present embodiment, since the gap 90c for detecting erroneous mounting having a size larger than the plate thickness of the protrusion 13a is provided at the tip of the stopper member 90, the lower end of the fixed screen 60 is a chamber corresponding to the gap. Will move inward. For this reason, the upper end portion of the fixed screen 60 is inclined more toward the indoor side, and it can be surely recognized that the fixed screen 60 is not correctly mounted.

  By the way, in the joinery mentioned above, as shown to FIGS. 7-2 and 15-2, the finding surface which faces the indoor side of the attachment member 40 with respect to the finding surface which faces the indoor side of the vertical frame 13 of the lower frame 12 is shown. The protrusion 12a is positioned outside the room. For this reason, even when the fixed screen 60 is attached to the indoor opening frame 10A, the base plate 71 of the lower corner part 70L only abuts on the locating surface facing the indoor side of the vertical frame 13, and the mounting member 40 A gap is formed between the facing surface facing the room.

  In the fixed vertical rod 63 extending upward from the lower corner part 70L, the above-mentioned gap does not become a problem since the flange base portion 63a continues upward in the portion where the flange base portion 63a is disposed. However, in the portion where the cover fin portion 63b is arranged in the fixed vertical rod 63, since the attachment member 40 is only located on the outdoor side, the above-described gap penetrates obliquely upward from the indoor side toward the outdoor side. There is a risk that external light may travel obliquely and reach the room.

  For this reason, in the joinery of the present embodiment, as shown in FIG. 15A, the support cover portion 53 of the vertical frame component 50 that covers both ends of the mounting member 40 protrudes beyond the upper surface of the mounting member 40. Is provided. Therefore, by appropriately adjusting the protruding height of the support cover portion 53, it is possible to reliably prevent a situation in which external light enters the room.

  When removing the fixed screen 60 from the indoor opening frame 10A, the stopper 91 is accommodated by operating the operating member 91 against the urging force of the projecting spring 92 as shown in FIG. 79, and when the fixed screen door 60 is moved upward with respect to the indoor side opening frame 10A from this state, the lower engagement fin portion 43c of the mounting member 40 extends from the engagement groove 62a of the fixed lower collar 62. It will deviate and the tip part of stopper member 90 will be in the state contacted to engagement board part 51 of vertical frame component 50. FIG. Therefore, in this state, even when the operation member 91 is released, the fixed lower rod 62 can be moved indoors relative to the indoor opening frame 10A, and the fixed screen door 60 is further moved downward. If the insertion protrusion piece 80 of the upper frame 11 is deviated from between the base plate 71 and the pressing protrusion piece 76 of the upper corner part 70U, the fixed screen door 60 can be removed from the indoor opening frame 10A.

  In the above-described embodiment, the indoor side opening frame 10A having the mounting member 40 as the lower edge is configured on the indoor side of the opening frame 10 provided with the glass window 20, and the fixed screen door 60 is provided on the indoor side opening frame 10A. Although the attached fitting is illustrated, this invention is not limited to these, The fixed screen door does not necessarily need to be provided, and the glass window does not need to be a vertical sliding window. Further, in the case where the fixed shoji is provided in the indoor opening frame, the screen door is exemplified in the above-described embodiment, but other shoji may be used.
