However, the filament is smaller than the known insect net. The net for screen doors, which has a fine mesh and a fine surface, can be fixed to the screen door frame easily, reliably, and stably. When fixing to the frame, it is possible to perform fixing so that the external force from the pressing member does not concentrate on the net.

1 to 4 show a first embodiment in which a screen door net fixing structure according to the present invention is applied to a screen door frame of an insect screen. This insect screen door is fixedly or slidably disposed in a building opening such as a window frame.
In the screen door, a screen door frame 11 formed in a rectangular shape by an aluminum horizontal frame member and a vertical frame member forming four sides, an insect repellent net 12 stretched on the frame body 11, and the net 12 And a pressing member 14 made of synthetic resin for fixing the frame 11 to the frame 11. The insect repellent net 12 uses a filament such as polyester fiber or polypropylene fiber having a fineness smaller than that of the known insect repellent net, and is woven in plain weave or Russell weave to form a finer mesh than the known insect repellent net. It is a thing.

  As shown in FIGS. 1 and 2, the horizontal frame member and the vertical frame member constituting the frame body 11 are provided with a locking groove in a concave step formed on the inner peripheral side of one surface along the net extending surface. 18 is formed. As clearly shown in FIG. 2, the locking groove 18 has a mouth narrowed by a pair of left and right inward protruding edges 19. The insect repellent net 12 is the synthetic resin pressing member in a state where the insect repellent net 12 is placed on one surface along the net extending surface provided with the locking groove 18 of the frame 11. 14 is inserted into the locking groove 18 and stretched and fixed to the frame body 11 in the manner described in detail below.

  The pressing member 14 is formed by extrusion molding of a synthetic resin. As clearly shown in FIGS. 2 and 3, the pressing member 14 is formed on the cover plate 15 that covers the locking groove 18 of the frame body 11. On the other hand, an elastically deformable leg portion that fits in an inward protruding edge 19 on both sides of the mouth portion via a net 12 is provided, that is, a pair of elastically deformable leg strips 16 are integrally provided. It is constituted by. Further, projecting portions 15 a made of a soft synthetic resin are integrally connected to both outer portions of the leg portions of the cover plate 15 in such a manner that the cover plate 15 is extended.

  On the other hand, the inward projecting edge 19 on the stretched side (left side in FIG. 2) of the net 12 in the locking groove 18 of the screen frame 11 is substantially parallel to the inward projecting edge 19 on the outer surface side. By providing the outer projecting wall 20 having a portion to be pressed, the soft projecting portion 15a is press-fitted together with the net 12, and a recess 21 is formed to sandwich and fix the net 12 between the projecting portion 15a. The inner surface shape of the concave portion 21 avoids damage to the net 12 by, for example, conforming to the outer surface shape of the projecting portion 15a or having an uneven shape in order to ensure the holding of the net 12 by the projecting portion 15a. Appropriate shape can be achieved. Further, the surface of the protrusion 15a of the cover plate 15 has streak-like irregularities that elastically bite into the eyes of the net 12 sandwiched between the protrusion 15a and the recess 21 along the longitudinal direction of the protrusion 15a. Or the surface of the protrusion 15a can be a rough surface that bites into the eyes of the net 12.

In the first embodiment shown in FIG. 2, the outer projection wall 20 is provided only on the outer surface side of the inward projecting edge 19 on the side where the net 12 is stretched in the locking groove 18 of the screen door frame 11. Thus, the concave portion 21 into which the soft protrusion 15a of the cover plate 15 is press-fitted is formed, but the concave portion 21 can also be provided on the inward protruding edge 19 on the opposite side. However, the recess 21 needs to be shallow enough to allow the soft protrusion 15a fitted therein to be inserted by deformation due to the pressing.

When the entire pair of legs 16 passes through the inside of the inward protruding edge 19 of the locking groove 18, the leg 16 returns to its original shape, and the locking edge 16 b is inward of the locking groove 18. Locking inside the protruding edge 19 via the net 12 prevents the pressing member 14 from coming off. In this state, the state in which the soft protrusion 15a of the cover plate 15 is press-fitted together with the net 12 in the recess 21 on the inward protrusion edge 19 of the locking groove 18 is held, and the soft protrusion 15a The net 12 is stably clamped and fixed between the concave portion 21 and the software.

In addition, when the net 12 is stretched on the frame 11 using the pressing member 14 for the screen door net, the net 12 is first inserted into the locking groove 18 of the frame 11 in the manner described above, contrary to the above operation. The pair of legs 16 of the pressing member 14 is pushed in via the step, and at the stage where final fixing is almost completed, the soft protrusion 15a of the cover plate 15 of the pressing member 14 is connected to the net in the locking groove 18. It is also possible to press fit into the recess 21 on the inward projecting edge 19 on the twelve tension side. In this case, the net 12 is temporarily fixed to the locking groove 18 by the pair of legs 16 in the pressing member 14, but the net stretched on the frame body 11 by the press-fitting of the protrusion 15 a to the concave portion 21 thereafter. If the protrusion 15 a is pushed into the recess 21 while the 12 is pulled in and the opposite side of the net 12 is already fixed to the frame 11, an appropriate tension can be applied to the net 12.
In this way, after the net 12 is fixed by the pressing member 14 about the four circumferences of the frame 11, the end work of the net 12 outside the pressing member 14 is excised, so that the tensioning work is performed. Complete.

  In the screen door net fixing structure having the above-described configuration, the soft protrusion 15 a continuously provided at the tip of the cover plate 15 is provided in the recess 21 provided on the outer surface side of the inward protrusion edge 16 of the screen frame 11. It is press-fitted together with the net 12, and the main net is clamped and fixed at this portion, that is, the soft protrusion 15a is press-fitted into the concave portion 21 to clamp the net 12 between them, so that the net 12 is soft On the other hand, the leg portion of the pressing member 14 also has a holding action of the net 12, but when the pressing member 14 is pushed into the locking groove 18 of the screen door frame body 11, 12 is slid moderately so as not to damage the net 12, and the leg portion causes the net 12 to be placed inside the inward protruding edge 16 when the pressing member 14 has been pushed into the locking groove 18.
