The act which tries to pry up can be prevented.
The hanging rod 32 has an extending piece 42 extending to the outer peripheral side, and the hinge 34 is concealed by the extending piece 42.

  As shown in FIGS. 1-1 and 4-1, a stopper 9 is attached to the middle of the upper surface of the lower frame 14. As shown in FIG. 6, a base portion 15 for attaching the stopper 9 is provided between the outer rail 43 and the inner rail 28 on the upper surface of the lower frame 14. The base portion 15 has a base plate 15a and a protrusion 15b provided on the base plate 15a so as to come into contact with the outdoor side surface of the rail 28 for the inner limb, so that the base plate 15a is fitted between the rails 43 and 28. It is arranged and fixed to the lower frame 14 with screws 44. Dovetail grooves 45 are formed on the left and right side surfaces of the protrusion 15b in the vertical direction, and stopper positioning holes 46 are formed at the left and right sides of the protrusion 15b of the substrate 15a. The stopper 9 is formed of a hard resin in a block shape, and engages an engagement portion 47 formed on one side surface with the dovetail groove 45 of the base portion 15 from above, and a protrusion 48 protruding from the lower surface is formed in the hole 46 of the base portion 15. And is detachably attached. A concave portion 49 is formed on the upper surface of the protruding portion 15b of the base portion 15 so that the stopper 9 can be easily pinched when the stopper 9 is pulled upward.

  As shown in FIGS. 1-1 (a) and 4-1 (a), the window 2 occupies approximately 2/3 of the lateral width of the window frame 1 and the face lattice 5 is inside. Since it is installed only on the outdoor side of the shoji 3, the shoji 2 can ensure a good view. Moreover, as shown in FIGS. 1-1 (b) and 4-1 (b), ventilation can be performed by opening the inner impeller 3, and in this state, the intrusion of a thief or the like can be prevented by the surface lattice 5, and Since the surface lattice 5 also serves as a screen door, insects can be prevented from entering. The inner shuffler 3 is stopped by the stopper 9, and at this time, as shown in FIG. 5 (a), the door toe 8 of the inner shredder 3 is positioned so as to overlap the indoor side of the operation lever 7 of the lock 6 of the face lattice 5. Therefore, even if an operator tries to operate the operation lever 7 by putting his hand through the gap between the cross bars 33 of the surface lattice 5, the operation cannot be performed. Therefore, there is no possibility that the lock 6 of the face lattice 5 is unlocked by a thief or the like. When unlocking the lock 6, the stopper 9 is pulled upward as shown in FIG. 7 (a), and then, as shown in FIGS. 1-2 (c) and 4-2 (c), Move left slightly. Then, as shown in FIG. 5B, since the operation lever 7 of the lock 6 is exposed to the indoor side, the unlocking operation can be easily performed from the indoor side. Even when the stopper 9 is removed, the inner shoji 3 stops at the position where the door-end rod 8 overlaps the indoor side of the calling rod 21 of the shoji 2 by the protrusion 15b of the base portion 15. Further, as shown in FIG. 7B, the removed stopper 9 can be prevented from being lost by being attached to the left side of the protruding portion 15 b of the base portion 15. Thereafter, as shown in FIGS. 1-2 (d) and 4-2 (d), it is possible to escape from the window by pushing and opening the surface lattice 5 outward.

  As described above, this window can secure a good viewability by the outer shoji 2 and can be ventilated by opening the inner shoji 3, and intrusion of a thief or the like by the face lattice 5 with the inner shoji 3 opened. Can be prevented. When the inner shoji 3 is opened, the door toe 8 is stopped by the stopper 9 at the position where the door rod 8 overlaps the indoor side of the operation lever 7 of the lock 6 of the face lattice 5, so that the lock 6 is released from the outdoor side. There is no risk of unlocking operation, and high crime prevention can be exhibited. If you want to open the face grid 5 in the event of an emergency such as a fire, the unlocking operation can be performed simply by pulling out the stopper 9 and opening the inner impeller 3, and the inner impeller 3 is already open when unlocked. You can escape quickly by simply pushing the grid 5 open.

FIG. 10 shows another embodiment of the stopper portion. An arm 51 is attached to the base portion 15 fixed to the lower frame 14 so as to be rotatable about an indoor / outdoor shaft 52, and a stopper 9 is attached to the tip of the arm 51. The stopper 9 engages with a hole 54 formed at the tip of the arm 51 with a pin 53 projecting inward toward the indoor side, is slidable in the indoor and outdoor directions, and is fitted around the pin 53. The spring 55 is biased toward the outdoor side. The stopper 9 has locking portions 56 projecting from the upper and lower portions of the outdoor side surface. The locking portion 56 is locked to a hook-like locked portion 57 provided on the upper surface of the base portion 15. It is fixed.
The function of the stopper 9 is the same as that of the detachable type described above, and when the inner shoji 3 is opened, the door toe 8 of the inner shoji 3 overlaps with the indoor side of the operation lever 7 of the lock 6. Then, the inner impingement 3 collides with the stopper 9 and stops, so that the unlocking operation of the lock 6 becomes impossible. As shown in FIG. 10B, since the shaft 52 of the arm 51 and the pin 53 of the stopper 9 are displaced vertically, the stopper 9 is lifted by the impact when the inner impingement 3 collides with the stopper 9. Can be prevented.
When unlocking the lock 6, the stopper 9 is slightly moved indoors with a finger to remove the locking portion 56 from the locked portion 57, and then the arm 51 is stopped as shown by the phantom line in the figure. Each 9 is rotated 180 ° around the shaft 52. Then, the stopper 9 moves to the left on the base portion 15, the locking portion 56 is locked to the locked portion 57 on the opposite side of the base portion 15, and the stopper 9 is fixed in a released state. According to this embodiment, since the stopper 9 is connected to the base portion 15 by the arm 51, there is no possibility that the stopper 9 is lost.

  FIG. 11 shows still another embodiment of the stopper portion, which can be moved left and right by horizontally rotating the stopper 9 around the axis 52 in the vertical direction via the arm 51. It is. The stopper 9 is biased downward by a spring 55, and a locking portion 56 protruding from the lower surface is locked to a locked portion 57 on the upper surface of the base portion 15. When releasing the stopper 9, the stopper 9 is slightly lifted upward, and the arm 51 and the stopper 9 are rotated 180 ° around the shaft 52 from the indoor side and moved to the left side as indicated by the phantom line in the figure.

12 and 13 show still another embodiment of the stopper portion, in which the stopper 9 is slidable in the left-right direction. The base portion 15 includes a case 15a and a guide rail 15b provided in the case 15a. The guide rail 15b is formed with a guide groove 57 opened upward in the left-right direction, and slide restricting portions 58a, 58b having wide opening widths are provided at two places on the left and right. The stopper 9 has a protrusion 59 provided on the upper surface protruding from a left and right elongated hole 60 formed on the upper surface of the case 15 a, and is biased upward by a spring 55. Further, as shown in FIGS. 12C and 13, the stopper 9 has a constricted portion 61 at the intermediate portion in the vertical direction, and the stopper lower portion 62 is fitted to the slide regulating portion 58a on the right side of the guide rail 15b. Slides are regulated.
When the inner pouch is opened, the door bottom of the inner peg 3 collides with the protrusion 59 protruding from the case 15 a of the stopper 9, and the door rod 8 of the inner pouch 3 overlaps the indoor side of the operation lever 7 of the lock 6. Then, the inner impingement 3 stops, and the unlocking operation of the lock 6 becomes impossible.
When releasing the stopper 9, as shown in FIG. 14 (a), the stopper 9 is pushed down with a finger, so that the stopper lower part 62 comes out below the slide restricting portion 58a, so as shown in FIG. 14 (b). Slide the stopper 9 to the left. When the stopper 9 is slid to the end of the long hole 60 and the finger is released, as shown in FIG. 14C, the stopper 9 is moved upward by the urging force of the spring 55, and the stopper lower portion 62 is moved to the left slide restricting portion. The stopper 9 is fixed in a state where the stopper 9 is released. According to the present embodiment, the operation of using or releasing the stopper 9 can be performed more easily, and there is no possibility of losing the stopper 9.

  The external shoji 2 may be fixed to the window frame 1 but slides to the right along the rails 50 and 43 (see FIG. 2) of the upper frame 17 and the lower frame 14 when the surface lattice 5 is opened. It can also be opened. The width of the external shoji 2 can be made substantially the same as that of the internal shoji 3.

  FIG. 9 shows another embodiment of the window according to the present invention, in which the inner impeller 3 and the face lattice 5 are installed on the left and right sides in the window frame 1. In this case, as shown in FIG. 7C, the stoppers 9 are attached to the left and right sides of the protrusion 15b of the base portion 15. According to this embodiment, as shown in FIG. 9 (b), the left and right inner limbs 3, 3 can be opened at the same time, so that more efficient ventilation can be performed. When the inner shoji 3 is opened, the door toe 8 is stopped by the stopper 9 at a position overlapping the indoor side of the operation lever 7 of the lock 6 of the face lattice 5, so that the lock 6 is unlocked from the outdoor side. There is no fear.

  The present invention is not limited to the embodiments described above. The intrusion restricting door has only to be ventilated and can be controlled from entering and exiting from the opening, in addition to the surface lattice as shown in the embodiment, in the frame formed by the reed ridge, punching metal, A wire mesh attached may be used. Further, the intrusion restricting door may extend and contract like a folding door or a telescopic gate. The operation part of the lock can be a rotary or slide type knob. However, when the French drop-type operation lever shown in the embodiment is used, the operation lever does not protrude from the lock case in the locked state. In addition, since it protrudes indoors during the unlocking operation, it is more preferable because the unlocking operation can be surely prevented by the door toe of the inner shoji. The means for stopping the inner impingement at the position where the door tip of the inner impingement overlaps the indoor side of the lock operating unit when the inner impeller is opened does not necessarily have to be a stopper attached to the lower frame. Moreover, a stopper can also be installed in an upper frame or a shoji. The form of the stopper and the base part is arbitrary, and by releasing the stopper, the stopper may be retracted from the inner rail running rail so that the inner shoulder can run on the rail.
