Therefore, it is possible to attach the operator handle 30 without increasing the size of the lower frame 12, and the design of the joinery is not impaired at all even when the frame 10 is made of resin. 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 frame 10 are provided with vertical frame components 50 at portions corresponding to both ends of the mounting member 40, respectively. 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. 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.

  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, 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. As shown in FIGS. 8A and 8B, in the present embodiment, the corner part 70 provided between the upper fixing rod 61 and the vertical fixing rod 63 and the lower fixing rod 62 and the vertical fixing rod 63 are provided.

And attached to the upper frame 11 via the mounting substrate 81. The insertion protrusion piece 80 is provided with a contact rib 82 at a portion of the pressing protrusion piece 76 that faces the pressing portion 76a. As shown in FIGS. 12-1 to 12-4, the abutment rib 82 protrudes from the support surface 80a facing the pressing protrusion 76 in the insertion protrusion piece 80 toward the outdoor side. 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 lower fixing rod 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 operation member 91a is disposed on a finding surface facing the room side of the base plate 71, and the base plate The connecting portion 91 b is connected to the stopper member 90 through the notch groove 71 a formed in the 71 and is disposed on the base plate 71. 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 lower fixing rod 62, and the operating member 91 can be moved in the longitudinal direction of the lower fixing rod 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 lower fixing rod 62 of the fixed screen 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 inclined so that the upper fixing 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 lower fixing rod 61 is maintained in a state where the height position of the upper fixing rod 61 is 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. Therefore, the vehicle goes over the protrusion 13a of the vertical frame 13 and comes into contact with the installation surface 56 above the notch 55 of the vertical frame component 50.

  Finally, if the fixed screen 60 is moved downward relative to the indoor opening frame 10 </ b> A and the lower engagement fin portion 43 c of the attachment member 40 is accommodated in the engagement groove 62 a of the lower fixing 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 upper fixing rod 61, the support surface 80a of the insertion projecting piece 80 and the pressing projecting piece 76 are provided. The surface (support surface) of the support portion 76b comes into contact with 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 vertical fixing rod 63 extending upward from the lower corner part 70L, the flange base portion 63a continues upward in the portion where the flange base portion 63a is arranged, so that the above-described gap does not become a problem. However, in the portion where the cover fin portion 63b is disposed in the vertical fixing 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 attachment member 40 extends from the engagement groove 62a of the lower fixing rod 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 hand is released from the operation member 91, the lower fixing rod 62 can be moved indoors with respect to the indoor opening frame 10A, and the fixed screen 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 opening frame 10A is configured on the indoor side of the frame body 10 provided with the glass window 20, and the joinery in which the fixed screen door 60 is mounted on the opening frame 10A is exemplified. Is not limited to these. That is, in the present invention, the glass window 20 is not necessarily provided, and the shoji is not limited to the screen door.

  Moreover, in embodiment mentioned above, although a press member is provided by forming a slit in a press protrusion piece part, this invention is not limited to this. For example, a coil spring or a leaf spring may be separately prepared, and when the shoji is attached to the opening frame by the pressing force of these springs, the opposing protruding piece portion may be brought into contact with one of the other finding surfaces. . In the above-described embodiment, when the pressing member is formed on the pressing protrusion, the pressing protrusion is provided on the shoji, while the insertion protruding piece is provided on the frame. A pressing protrusion may be provided on the frame.
