DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock and a sash structure attached to a screen door and a sash for security of a building.

[0002]

2. Description of the Related Art In a state in which a sash is locked, a reinforced glass or a laminated glass is used as the glass to prevent crime and a burglar cannot be easily entered from the outside. If you go out with the screen door, you can easily enter the empty nest. It is easy to lock the screen, but even if you lock the screen like a crescent, you can easily break into the screen and enter the screen.
Even if you lock the screen door after taking some measures to prevent the screen net from being broken, attaching a lock with a plug-in key other than the crescent to the screen door may result in loss of the plug-in key and sash in case of fire. It is not preferable when the escape of the material is considered.

[0003]

According to the present invention, the screen door and the sash are locked so that the operation portion of the lock is located at a position where operation from the outside is difficult. It can be easily unlocked from inside. Make sure that the screen screen is not easily broken. The purpose of the above is to provide the screen door with the same security performance as a glass shoji.

[0004]

[Means for Solving the Problems] (A) A crescent ♀ is attached to the vertical frame of a shoji screen. (Figs. 1 and 2) (b) Attach Crescent ♂ to the glass screen frame.
(Fig. 1, Fig. 3, Fig. 4, Fig. 2) (c) Attach a protruding plate (11) to the glass screen frame. (Figs. 2 and 1) (d) Attach the bearing (13) to the protruding plate (11). (FIGS. 2 and 1) (c) Attach a rotating shaft supported on both sides by a glass screen frame and a bearing (13) to Crescent. (Fig. 2
(Fig. 3, Fig. 4, Fig. 1) (d) Attach an operation lever to the shaft longer than the distance between each glass of the two glass sashes of the pulling sash (Fig. 2, Fig. 3, Fig. 4, Fig. 1). (E) Attach a spherical roller (12) that rotates around the operation lever to the vicinity of the tip of the operation lever (Figs. 2, 3, 4, and 1) (f) Punching in addition to the insect screen of the screen door A net that is harder to cut than an insect net, such as a net made of metal or a wire. (FIGS. 5 and 1) Alternatively, a grid is attached to the screen door. (Fig. 7) (g) Attach a plate-shaped guide rail (19) to the indoor glass screen frame. (Fig. 1)

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A left hand is inserted through a gap on the left side of a sash as viewed from the indoor side (lower side in FIG. 1), and a vertical frame ′ of a screen door is pressed to a left side (a sash frame). When rotated about 180 degrees in the direction of FIG. 3), the crescent 回 転 also rotates and is locked to the crescent 、, and the screen door frame and the glass screen frame are connected and fixed (FIG. 4). Move the glass screen in front (inside of the room) to the right to measure the ventilation of the screen door and enable the function as a screen door. In this state, if the empty nest tries to enter from the outside (the upper part in FIG. 1), it cannot enter because the screen door and the glass shoji on the outdoor side are fixed. Even if you cut a net containing wires or the like so that you can enter it to unlock it, you cannot put your hands on the operating lever of the lock because it is obstructed by the glass door inside (Fig. 7). In order to break through, it is necessary to cut the net containing the wire of the screen door etc. to a size that allows the body to enter. When a grid is attached as shown in FIG. 6, it is necessary to cut the grid and invade it. In the state of FIG. 8, if the empty nest attempts to unlock by rotating the operation lever by inserting a wire or the like from the gap (20) between the glass screen frame and the glass, the operation lever is longer than the glass interval. The roller cannot be unlocked because the roller (12) attached to the operation lever hits the glass and the operation lever does not rotate. If the glass screen is closed, it can be easily unlocked from inside. When the indoor glass shoji is moved to the left from the state of FIG.
However, a guide rail (19) is attached to the glass frame because it hinders the movement of the glass frame. As shown in FIG. 9, the roller (12) hits the guide rail (19) and rotates, and at the same time, the operating lever is pushed back to prevent the opening and closing of the glass sash. To open the other side (the right side when viewed from the room side) and open the room, move the screen door to the right and the outside glass door to the left as viewed from the room side and operate the other operation lever as shown in FIG. By doing so, it is possible to lock the screen door moved to the right side.

[0006]

FIG. 11, FIG. 12, FIG. 13, and FIG. 14 show an embodiment in which two latches are used in place of the crescent. The gear (14), the gear (15), and the gear (16) mesh and rotate in conjunction with each other. (FIGS. 13, 14, and 12) When the operation lever is rotated in the direction of arrow (10), the gear (14) rotates. (FIG. 13) The gear (15) meshing with the gear (14) rotates in the opposite direction, and the catch (17) attached to the gear (15) is locked to the catch (18). (FIG. 14) Similarly, the gear (16) meshing with the gear (15) also rotates, and the locking lock (17) 'attached to the gear (16) is locked to the locking lock (18)'. (FIG. 14) The screen door and the glass screen are fixed in the same manner as in the case of the crescent. In the case of the type with four draws, the operation method is the same as that of the two draws with the structure in which the two draws are symmetrical. FIG. 15 shows a case in which the center is ventilated with four sliding doors, and the screen door frame becomes a main frame, the two screen doors are integrated, and a bur is inserted between the two screen doors to break. Is preventing things. FIG. 16 shows a case in which both sides are ventilated with four drawer types. A stopper is attached to the center of the glass shoji, and the two glass shojis each have one side (right or left).
Not to move to. If there is no stopper, as shown in FIG. 17, both of the glass sashes can move to the right, so that it is possible to cut a part of the net of the screen door, insert a hand from the outside, and attach a hand to the operation lever. The lifting and lowering type has a structure like two vertically drawn. After locking from the inside (right side) in the state of FIG. 18, if the glass sash is raised as shown in FIG. 19, the operation lever is sandwiched by the glass and cannot be operated.

[0007]

According to the present invention, the screen door has the same security as a glass shoji with the above structure. At least there is no chance of entering the burglar in a moment, and the inside can be easily unlocked.
