The hook member 40 has a common configuration on the left and right sides, and as shown in FIG. 7, the hook mounting plate portion 41 having a substantially rectangular flat plate shape and the hook member 40 are bent in a direction substantially perpendicular to one end of the hook mounting plate portion 41. Alternatively, the hook portion 42 that is curved and extended and the hook contact portion (curved end portion) 43 that is bent or curved and extends in a direction substantially perpendicular to the extended end portion of the hook portion 42 are integrally molded. Is. In the illustrated example, the hook mounting plate portion 41, the hook portion 42, and the hook contact portion 43 are all configured to have the same width. The extending direction of the hook contact portion 43 is opposite to the extending direction of the hook mounting plate portion 41 with respect to the hook portion 42.

As shown in FIGS. 2 to 5, the hook member 40 is hooked in a state where the hook portion 42 is located below the hook mounting plate portion 41 and the hook portion 42 extends substantially horizontally along the prospective direction. It is fixed to the finding surface 24a facing the outside of the screen door vertical frame 24 via the mounting plate portion 41. As a method of fixing the hook member 40 to the screen door vertical frame 24, for example, a mounting screw may be screwed into the screen door vertical frame 24 via the hook mounting plate portion 41. A metal plate 44 is arranged as a back plate in a portion where the mounting screws are screwed inside the screen door vertical frame 24.

The hook receiving member 50 has a symmetrical shape on the left and right sides, and as shown in FIG. 7, the hook receiving member 50 is bent or curved in a direction substantially perpendicular to the flat plate-shaped receiving mounting plate portion 51 and one end of the receiving mounting plate portion 51. The extending receiving surface plate portion (hook receiving surface) 52 is integrally molded. The receiving surface plate portion 52 is formed with a square hole (notch) 52a having a size through which the hook portion 42 and the hook contact portion 43 of the hook member 40 can be inserted. The square hole 52a is a horizontally long rectangular through hole, and is formed at a position substantially at the center of the receiving surface plate portion 52. More specifically, the square hole 52a is configured such that the dimension along the longitudinal direction is larger than the width along the left and right sides of the hook portion 42. The dimension of the square hole 52a along the short side is formed so as to be substantially the same as the extending length of the hook contact portion 43.

As shown in FIGS. 2 to 5, the hook receiving member 50 is inside the vertical frame 13 via the receiving mounting plate portion 51 in a state where the receiving surface plate portion 52 is inclined so as to be gradually upward toward the outside of the room. It is fixed to the veneer 10e, and the hook receiving portion 52A is configured in the portion below the square hole 52a, and the upward movement restricting portion 52B is configured in the portion above the square hole 52a. As a method of fixing the hook receiving member 50 to the vertical frame 13, for example, a mounting screw may be screwed into the vertical frame 13 via the hook mounting plate portion 41. A metal plate 53 is arranged as a back plate in a portion of the hollow portion 10c of the vertical frame 13 where the mounting screws are screwed. The position for fixing the hook receiving member 50 is when the screen door 20 is arranged along the substantially vertical direction with the lower engaging member 25c engaged with the engaging piece portion 10j of the lower frame 12 (hereinafter, this state). The hook receiving portion 52A located below the square hole 52a in the receiving surface plate portion 52 is positioned to face the hook contact portion 43 of the hook member 40. It is set as.

Here, in the square hole 52a formed in the receiving surface plate portion 52 of the hook receiving member 50, the distance from the upward movement restricting portion 52B to the hook receiving portion 52A is substantially the same as the dimension along the upper and lower sides of the hook contact portion 43. It is formed like this. However, the hook receiving member 50 is fixed to the vertical frame 13 in a state where the receiving surface plate portion 52 is tilted. Therefore, in the state of being fixed to the vertical frame 13, the vertical dimension between the upward movement restricting portion 52B and the hook receiving portion 52A is slightly shorter than the dimension of the hook contact portion 43. In the first embodiment, when the screen door 20 is arranged at the mounting position, as shown in FIG. 7B, the upper movement restricting portion 52B is located slightly above the upper surface of the hook portion 42 and receives the hook. The fixed positions of the hook member 40 and the hook receiving member 50 are set in advance so that the hook portion 42 penetrates the receiving surface plate portion 52 in a state where the portion 52A is located slightly above the lower end of the hook contact portion 43. It has been adjusted.

In order to allow the hook portion 42 to penetrate the square hole 52a of the hook receiving member 50, first, as shown on the right side of FIG. 5, the engaging member 25c of the two corner blocks 25 provided in the lower corner of the screen door 20 is projected. On the other hand, the engaging member (upper engaging member) 25c of the two corner blocks 25 provided in the upper corner of the screen door 20 is regressed. From this state, as shown on the left side in FIG. 5, for example, with the screen door 20 in an oblique posture, the engaging member 25c in the lower corner is first engaged with the engaging piece portion 10j of the lower frame 12. In a state where the engaging member 25c in the lower corner is engaged with the engaging piece portion 10j of the lower frame 12, as described above, the screen door lower stile 23 moves downward with respect to the lower frame 12 and is out of the plane along the prospective direction. Since movement in the direction is restricted, if the posture is changed so that the upper portion of the screen door 20 is brought close to the frame body 10, the hook portion 42 of the hook member 40 provided in the screen door 20 becomes the hook receiving member of the frame body 10. The hook portion 42 will move in the prospective direction with respect to the 50, and the hook portion 42 will be penetrated through the square hole 52a of the hook receiving member 50. At that time, since the receiving surface plate portion 52 provided with the square hole 52a is inclined, even if the heights of the hook portion 42 and the square hole 52a are slightly different, the receiving surface plate portion 52 serves as a guide and the hook portion. 42 can be inserted into the square hole 52a. After the hook portion 42 has penetrated the square hole 52a of the hook receiving member 50, if the engaging member 25c of the two corner blocks 25 provided in the upper corner of the screen door 20 is moved upward, the upper frame 11 is engaged. It is in a state of being fitted into the joint hole 10k, and the screen door 20 is in a state of being supported by the frame body 10.

Although not clearly shown in the figure, the hook portion 42 can also be moved in the prospective direction while keeping the screen door 20 in the vertical direction with all the upper and lower engaging members 25c retracted. It is possible to penetrate the square hole 52a. The screen door 20 can be supported by the frame body 10 by operating the engaging member 25c in a protruding state after the hook portion 42 has penetrated the square hole 52a of the hook receiving member 50.

In any case, in the above-mentioned fittings, if the screen door 20 is moved along the extending direction of the hook portion 42 with respect to the frame body 10, in other words, if the screen door 20 is moved in the prospective direction, the hook hit. The contact portion 43 penetrates the square hole 52a and comes into contact with the hook receiving portion 52A. Therefore, even in a situation where the frame G is arranged so as to protrude from the indoor side of the frame body 10, the screen door 20 can be easily attached to and detached from the frame body 10 by operating the screen door 20 from the indoor side. It becomes.

As described above, when the hook portion 42 penetrates the square hole 52a of the hook receiving member 50, the hook receiving portion 52A is positioned slightly above the lower end of the hook contact portion 43. Therefore, when the screen door 20 is supported by the frame body 10, even if the operation of moving the upper engaging member 25c upward is forgotten, or the engaging member 25c in a state of protruding upward is impacted or vibrated. Even if the screen door 20 moves downward due to the above, the hook contact portion 43 of the hook portion 42 abuts on the hook receiving portion 52A, so that the screen door 20 moves downward with respect to the frame body 10 or faces toward the indoor side. It does not move outward, and it is possible to prevent the screen door 20 from falling off. Further, since the upper movement restricting portion 52B is located slightly above the upper surface of the hook portion 42, the upward movement of the screen door 20 with respect to the frame body 10 is restricted. As a result, for example, it is possible to prevent a situation in which the upper engaging member 25c is pushed downward by moving the screen door 20 upward with respect to the frame body 10.
