Such a second engagement member 50 can be easily attached to the receiving frame 13 without using a tool, like the first engagement member 30.

  When the movable frame 12 and the receiving frame 13 are joined to each other, the movable frame 12 and the receiving frame 13 having the hooking device constituted by the first and second engaging members 30 and 50 are covered with the cover 27 of the movable frame 12. The protrusion 29 and the protrusion 33 of the first engaging member 30 are inserted into the receiving groove 41 along the longitudinal direction of the receiving frame 13 to which the second engaging member 50 is attached. The gap at the time of joining of the receiving frame 13 can be eliminated, which is preferable in terms of insect prevention and aesthetics.

  In the above-described embodiment, the first engagement member 30 is attached to the movable frame 12 and the second engagement member 50 is attached to the receiving frame 13. It is also possible to attach two engaging members 50 and attach the first engaging member 30 to the receiving frame 13. The same applies to the second embodiment described below.

10 to 11 show a second embodiment of the present invention. In the second embodiment, portions common to the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted below.
The movable frame 112 in the second embodiment has substantially the same configuration as the movable frame 12 in the first embodiment, and the first engagement member 130 of the latching device in the second embodiment is Except for the configuration corresponding to the locking piece 37 in the first embodiment, it has substantially the same configuration as the first engagement member 30 in the first embodiment.

As shown in FIG. 10A, the first engagement member 130 is a position spaced apart in the longitudinal direction of the back surface as a locking portion piece 137 provided on the back surface opposite to the side on which the protruding portion 33 is provided. Thus, the first engaging member 130 has locking walls 137a protruding outward at positions that are point-symmetric with respect to one point on the center line.
The pair of locking walls 137a are inserted into the opening between the opposing mounting edges 26 (the state shown in FIG. 10A), and the longitudinal direction of the first engaging member 130 is inserted. Is directed to the longitudinal direction of the opening (the state shown in FIG. 10B), the pair of locking walls 137a are engaged with the mounting edge 26, and from this state, the pair of locking walls 137a are moved. When the first engaging member 130 is tilted in the direction away from the mounting edge 26, both the locking walls 137a are within the width of the opening between the mounting edges 26 so that they can be inserted into and removed from the opening. It is configured.

Further, in the first engaging member 130, as shown in FIG. 10A, when the locking wall 137a is engaged with one of the mounting edges 26, the first engaging member 130 is elastically slightly protruded and mounted on the opposite side. A pair of elastic locking pieces 139 that engage with the edge 26 are provided. When the first engaging member is rotated in a direction to disengage the engaging wall 137a from the mounting edge 26 in order to release the first engaging member 130, the elastic engaging piece 139 is somewhat It is necessary that the engagement with the mounting edge 26 is disengaged by applying this force.
Note that, as shown in FIG. 10C, the tilt of the first engagement member 130 is suppressed by the cover 27 attached to the movable frame 112, as in the first embodiment.

On the other hand, in the second embodiment, the receiving frame 113 for attaching the second engaging member is the same shape as the movable frame 112, and therefore has the same shape as the movable frame 12 of the first embodiment. Therefore, the same reference numerals as those of the movable frame 112 are given and description thereof is omitted.
As shown in FIG. 11A, the second engaging member 150 attached to the receiving frame 113 has a receiving groove 152 extending in the longitudinal direction where the protruding portion 33 of the first engaging member 130 is inserted. An iron plate 164 facing the magnet 61 and the yoke 62 in the protruding portion 33 of the first engagement member 130 is accommodated in the case 151 provided, and the iron plate 164 is formed on the inner bottom of the receiving groove 152 in the case 151. An exposure hole 153 is provided. When the iron plate 164 is accommodated in the case 151, the iron plate 164 is inserted into the inside through a hole provided at the end of the case and is fixed by an appropriate means, or when the case 151 is molded with a synthetic resin, An appropriate means such as embedding the iron plate 164 can be adopted.

  The case 151 of the second engaging member 150 has a locking piece 137 in the first locking member 130 as a means for locking the opposite mounting edge 26 in the receiving frame 113 on the back side thereof. Although a configuration in which a pair of locking portion pieces 177 having substantially the same configuration is provided is shown, the second engagement member 150 is used as a means for locking to the mounting edge 26. In the state inclined from the mounting posture, the locking to the mounting edge 26 is released, but in the final mounting posture, the configuration in which it is locked to the mounting edge 26, for example, as described above with reference to FIGS. Such locking means for the first engaging member 30 can also be employed.

A pair of locking part pieces 177 provided on the back side of the case 151 of the second engaging member 150 shown in FIG. 11 is substantially the same as the locking part piece 137 in the first locking member 130. Specifically, in the case 151, on both sides of the central convex portion 154 on the back surface of the case 151, at one point on the center line of the second engagement member 150 at positions spaced apart in the longitudinal direction of the back surface. It is configured as a locking part piece 177 having a locking wall 177a projecting outwards with point symmetry. The locking wall 177a is engaged with and disengaged from the opposing mounting edge 26 in the receiving frame 113. In the state where the locking wall 177a is inclined from the final mounting posture as shown in FIG. The engaging pieces 177 can be inserted into and removed from the space 26, but in the mounting posture as shown in FIG. 11B, the locking wall 177 a is locked to the mounting edge 26.
Similarly to the first locking member 130, when the locking wall 177 a is engaged with one mounting edge 26, a pair of elastic members that protrude slightly elastically and engage with the opposite mounting edge 26. A locking piece 179 is provided.

  Further, as shown in FIG. 11 (c), the tilt of the engaging member 150 can be suppressed above and below the engaging member 150 in the receiving frame 113 that locks the second engaging member 150. Specifically, a cover 127 having an outer shape substantially the same shape as that of the engaging member 150 is attached to the mounting edge 26 in a state in which the second engaging member 150 is in close contact with the end face. Thereby, even if some external force acts on the second engagement member 150, it can be prevented from tilting.

  When the movable frame 112 and the receiving frame 113 having the above-described configuration are joined, the first engagement member 130 and the protrusions 33 and 29 of the cover 27 in the movable frame to which the first engagement member 130 is attached are the second engagement member 150 and The receiving frame 113 to which the movable frame 112 and the receiving frame 113 are attached is fitted into the receiving grooves 152 and 129 along the longitudinal direction of the cover 127 so that a gap at the time of joining the movable frame 112 and the receiving frame 113 can be eliminated.
