It is attached to the frame material 33. In this state, the side wall portion of the side frame member 33 and the side wall constituting portion 34a of the side wall member 34 face each other, and the housing groove 33a is formed between them.

  As shown in FIGS. 3 and 4, the net body 40 is configured by supporting four sides of a net-like part 41 having a rectangular shape by frame parts 42. In the first embodiment, the net 41 is configured by knitting a resin yarn such as polypropylene. The frame portion 42 includes a frame base portion 42a having a probable dimension that can be received in the receiving grooves 31a, 32a, and 33a provided in the frame materials 31, 32, and 33, and a prospective surface that is the inner peripheral side of the frame base portion 42a. It has a rectangular frame shape having a pair of support pieces 42b projecting on the inner peripheral side, and can be inserted into the receiving grooves 31a, 32a, 33a of the frame members 31, 32, 33 respectively. The dimensions are configured. The support piece 42b is a thin plate-like portion protruding so as to be juxtaposed in the expected direction in the frame base portion 42a, and is formed integrally with the frame base portion 42a. However, in the first embodiment, the frame base portion 42a is molded from semi-rigid polyvinyl chloride, and the support piece 42b is molded from soft polyvinyl chloride. As is apparent from the drawing, the pair of support pieces 42b are configured such that the protruding lengths from the frame base 42a are different from each other.

  The frame base portion 42a of the frame portion 42 is provided with an engaging portion 42c and a tapered portion 42d. The engaging portion 42c is a portion that protrudes from the both-side finding surface of the frame base portion 42a. These engaging portions 42c are formed in such a size that when the frame portion 42 is inserted into the receiving grooves 31a, 32a, 33a of the upper frame member 32 and the side frame member 33, they can simultaneously abut against the inner surfaces facing each other. It is. The tapered portion 42d is configured by providing inclined surfaces 42e on both sides of the frame base portion 42a. Specifically, the probable dimensions of the portions extending from the respective engaging portions 42c provided on the frame base 42a to the outer peripheral edge of the frame base 42a are inclined on both sides of the frame base 42a so as to gradually decrease toward the outer peripheral side. A tapered portion 42d is formed by providing the surface 42e.

  Furthermore, the frame base portion 42a of the frame portion 42 includes a core member 43 therein. The core material 43 is a steel material (for example, spring steel, hard steel wire, piano wire) called a flat wire having a flat rectangular cross section whose thickness is smaller than the plate width, and the flat surface has a prospective direction. Are arranged along the longitudinal direction of each side in the frame base 42a. The core member 43 may be disposed inside the frame base portion 42a by, for example, co-extrusion with the frame base portion 42a, or may be inserted later into the preformed frame base portion 42a. It doesn't matter. In any case, the frame portion 42 and the core material 43 are once formed into a linear shape, and then formed into a rectangular frame shape by being deformed into a rectangular shape along the outer shape of the mesh portion 41. Both end portions of the frame portion 42 are connected to each other by bonding or welding. The core members 43 are also connected to each other inside the frame base portion 42a so as to have an endless rectangular shape. As a method of connecting both end portions of the core material 43, for example, both end portions of the core material 43 are inserted into the cylinder body 43a, and external force is applied from the outer periphery of the cylinder body 43a to crush the cylinder body 43a (clamping). ). Further, the end portions may be connected to each other by bonding or welding the both ends of the core material 43 to each other. In addition, the core material 43 does not necessarily need to be endless, and even if the end part is somewhat apart, there is no functional problem. Moreover, you may make it comprise the core material 43 combining several steel materials. For example, an outer shape in which the upper side of the frame part 42 is integrated with the left and right sides is a U-shaped steel material, and an outer shape in which the lower side of the frame part 42 is integrated with the left and right sides is a U-shape. It is also possible to form a rectangular core material 43 by combining these steel materials.

  As shown in FIGS. 5 (a) and 5 (b), the edge of the mesh portion 41 is inserted between the support pieces 42b, and the frame portion 42 is thermally welded or bonded from this state. The edge portion of the mesh portion 41 is supported between the support pieces 42b. In this case, since the protruding lengths of the support pieces 42b from the frame base portion 42a are different from each other, the support pieces 42b having a large protruding length function as a guide when the mesh portion 41 is inserted between the support pieces 42b. Thus, the operation of inserting the mesh portion 41 can be facilitated.

  In the net body 40 configured as described above, the metal core member 43 disposed along the longitudinal direction of each side constituting the frame portion 42 functions to maintain the outer shape of the frame portion 42. , Handling alone is easy. In particular, when the core member 43 is configured in an endless manner as in the first embodiment, the above-described function becomes more remarkable. In addition, as shown in FIGS. 1 and 2, the core member 43 disposed in the frame portion 42 has a flat flat surface extending along the prospective direction of the frame base portion 42a, and thus the frame base portion 42a from the outer peripheral side. If an external force is applied to, it can be elastically deformed relatively easily. Furthermore, a tapered portion 42d is provided on the outer peripheral side edge of the frame base portion 42a. Therefore, according to this net | network body 40, the insertion operation | work of the frame part 42 with respect to the accommodation groove | channels 31a, 32a, 33a of the frame materials 31,32,33 can be made easy.

  Further, after the frame portion 42 of the mesh body 40 is inserted into the receiving grooves 31a, 32a, 33a of the frame members 31, 32, 33, the engaging portion 42c contacts the inner surface of the receiving grooves 31a, 32a, 33a. In this state, since the core member 43 functions to maintain the outer shape of the frame portion 42, there is no risk of inadvertently falling off the frame members 31, 32, 33.

  Even in the above-described state, if the engaging wall portion 33d is detached from the side frame member 33, the frame portions 42 located on both sides of the mesh body 40 are exposed to the indoor side. Therefore, even when it is necessary to remove the mesh body 40 from the support frame 30 such as maintenance or replacement of the mesh body 40 or cleaning of the joinery, the work can be easily performed.

  In the net body 140 configured as described above, the metal core member 143 disposed along the longitudinal direction of each side constituting the frame portion 142 functions so as to maintain the outer shape of the frame portion 142. , Handling alone is easy. In particular, when the core member 143 is configured in an endless manner as in the second embodiment, the above-described function becomes more remarkable. In addition, as shown in FIGS. 6 and 7, the core member 143 disposed in the frame portion 142 has a flat flat surface extending along the prospective direction of the frame base portion 142 a, and thus the frame base portion 142 a from the outer peripheral side. If an external force is applied to, it can be elastically deformed relatively easily. Further, a tapered portion 142c is provided on the outer peripheral side edge portion of the frame base portion 142a. Further, as shown in FIG. 13, with respect to the frame material 133 disposed on one vertical frame 113, the protruding side wall from the frame base portion 133b is larger in the outdoor side wall portion 133c than the indoor side wall portion 133c. Therefore, if the frame 142 is brought into contact with the outdoor side wall 133c, it functions as a guide to the accommodation groove 133a. Therefore, according to the mesh body 140, the operation of inserting the frame portion 142 into the housing grooves 131a, 132a, 133a of the frame members 131, 132, 133 can be facilitated.

  Further, after the frame portion 142 of the mesh body 140 is inserted into the receiving grooves 131a, 132a, and 133a of the frame members 131, 132, and 133, the engaging portion 142b is engaged with the engaging strip 133e of the receiving grooves 131a, 132a, and 133a. Since the core member 143 functions so as to maintain the outer shape of the frame portion 142 in a state of being opposed to the frame member 142, there is no possibility that the frame member 131, 132, 133 is accidentally dropped off.

  Even in the above-described state, if the pulling handle 144 is operated, the frame portion 142 is appropriately deformed to the inner peripheral side and comes out of the housing groove 131a of the frame member 131. Therefore, even when it becomes necessary to remove the mesh body 140 from the support frame body 130, for example, when maintenance or replacement of the mesh body 140 or cleaning of the joinery is performed, the work can be easily performed.

  In addition, although Embodiment 1 and Embodiment 2 mentioned above have illustrated about the net | network body provided as a fixed screen door in the room interior side of a vertical sliding window, this invention is not limited to these. For example, in a fitting that opens to the indoor side of the shoji, it may be provided as a fixed screen in a part that is on the outdoor side of the shoji. The present invention can also be applied to a net body provided as a screen door. In the case of the movable screen door, the net body is provided on the bag which is the support frame body, and is supported so as to be slidable with respect to the opening frame.

  Further, in Embodiment 1 and Embodiment 2 described above, a net having a rectangular outer shape is illustrated, but the outer shape of the net is not necessarily limited to a rectangular shape, and may be a polygon other than a rectangle or a circle. There may be.

  Furthermore, in Embodiment 1 and Embodiment 2 described above, the accommodation groove is formed on the prospective surface of the frame material, but the accommodation groove may be provided on the finding surface of the frame material.

  Furthermore, in Embodiment 1 and Embodiment 2 described above, a rectangular wire is applied as the core material, but the cross section of the core material may be circular or polygonal other than square. The core material need not be solid, and a hollow material may be applied.
