Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface lattice that can be opened from the inside, and its purpose is usually to function as a crime prevention surface lattice. In the event of a fire or the like, the surface lattice is released from the room to escape to the outside. It is possible to provide a surface lattice that can be opened from the inside of a room that can be easily retrofitted using an outermost sash wing in an opening where a sash frame is already formed in an existing building or the like.

[0002]

BACKGROUND OF THE INVENTION Generally, a screen lattice is often provided outside a window of a building such as a house for the purpose of crime prevention or decoration. This area lattice is firmly fixed to the outside of the window so that it cannot be easily opened from the outside. However, this area lattice is effective for crime prevention or decoration, but on the contrary, when a person left behind in a room during a disaster such as a fire escapes from the window to the outside and evacuates, this area lattice is used. Since it is attached to the outside of the window in a fixed state, it is not possible to escape to the outside through the window and evacuate, and people left behind inside the room may suffer disasters.

Further, in order to install the main body of the surface lattice, it is conceivable to open one side of a frame body provided on the upper, lower, left and right portions outside the window portion and remove the main body of the surface lattice. However, if the surface lattice main body is thus opened from the open portion provided on one side of the frame, the surface lattice main body can be easily removed not only from the indoor side but also from the outdoor side. There was a problem that the original role of crime prevention of the lattice was not exerted.

[0004]

2. Description of the Related Art Therefore, as a surface lattice which normally functions as a surface lattice for crime prevention and can be escaped to the outside by opening the surface lattice from the room in the event of a fire or the like, there is one already disclosed by the present inventor. . This area lattice will be described with reference to FIG. In a surface lattice attached to the outside of a sash (A) in a building, a vertical frame (C) is fitted to the left and right sash wings (B) on the outermost side of the sash (A), and the vertical frame (C) ) Above and below the horizontal lattice body (D) having at least one row of rails on which the plane lattice body (D) can slide, respectively, and these vertical frame bodies (C) and horizontal frame bodies are provided with screws (not shown). No. 5), the through holes (E) in the wall width direction are provided in the play space of the sash (A) in the inner side of the frame body, and the through holes (E) are locked in the wall width direction. A bar (F) is provided, and the length of the locking bar (F) is longer than that of a person's arm. The locking bar (F) is directed toward the indoor side of the sash (A). The vertical frame body (C) is provided with an operating means (G) for moving and is close to the sash (A). When the stop bar (F) moves toward the outside of the room by the operation of the operating means (G), the tip of the stop bar is inserted and locked, and when the stop bar (F) moves toward the indoor side, the insertion locked state is released. The insertion locking hole (H) was provided.

[0005]

The above-mentioned surface lattice is excellent in that the surface lattice can be opened from the room to escape outdoors in the event of a disaster such as a fire, and the outdoor lattice cannot be removed from the outdoors. Although it was a device, it had the following problems. A through hole must be provided in the frame of the sash in order to provide a locking bar in the play space in the depth direction on the frame side of the sash. It has been too difficult and time-consuming to attach the surface lattice to the frame body of the sash having the sash attached to its part. Further, since the operating means is provided on the indoor side of the sash, there is a problem in that the operating means can be seen from the room and the operation is performed by a child's mischief.

The present invention has been made in view of the above-mentioned conventional circumstances, and in the event of a disaster such as a fire, the plane lattice main body is provided on one side or the left or right side of the frame body provided on the upper, lower, left and right portions of the window portion It can be opened on both sides, so that you can easily escape to the outside and evacuate, and it can be locked and locked so that it can not be opened by operation from the outside, By operating the provided operating rod from the inside of the room, the above-mentioned locked and fixed state can be easily released to open the main body of the surface lattice, and the surface lattice that can perform the function of crime prevention can be released from the interior. The present invention has continued to earnestly investigate a surface lattice that can be opened from the room and can be easily attached later to the opening where the sash is already formed.

[0007]

That is, according to the present invention, in a plane lattice attached to the outside of a sash in a building, a vertical frame is fitted to the left and right sash wings on the outermost sides of the sash. Horizontal frame bodies each having at least one row of rails on which the plane lattice main body can slide are provided, and these vertical frame bodies and horizontal frame bodies are mutually fixed by screws, and the vicinity of the frame body of the sash Is provided with a locking bar in the wall width direction, operating means for moving the locking bar toward the indoor side is provided on the inner side of the vertical frame, and the vertical frame is provided near the sash. When the locking bar moves toward the outdoor side by the operation of the operating means, the tip is inserted and locked, and when the locking bar moves toward the indoor side, the insertion locking state is released. What is provided A surface lattice that can be opened from the interior, and a surface lattice that is attached to the outside of the sash in a building, in which the left and right sash wings on the outermost sides of the sash are fitted with a substantially U-shaped vertical frame body, Horizontal frames each having at least one row of rails on which the plane lattice main body can slide are provided above and below the vertical frame body, and the vertical frame body and the horizontal frame body are fixed to each other by screws. An insertion hole is provided in a contact surface of the body with the main body of the surface lattice, and an operation means is provided in at least one of the vertical frame bodies, and the operation means is movable only when the operation means is tilted toward the indoor side. And a tip of the locking member inserted through the insertion hole when the locking member moves toward the outdoor side by the operation of the operating means at the side end portion of the surface lattice main body. Stopped and turned toward the interior An object of the present invention is to solve the above problems by providing a surface lattice that can be released from a room, characterized in that a locking piece having an insertion locking hole that releases the insertion locking state when moved is provided. It is what

[0008]

Since the operating means is provided inside the vertical frame body of the plane lattice or in the vertical frame body formed in a substantially U-shape, a hole for inserting the locking bar is formed in the wall body or the frame body of the sash. It does not need to be opened, so work efficiency is good, and since no holes are made in the wall or frame of the sash, it is easy to rain. Since it is attached later using the outermost sash blade, the area lattice can be easily attached. Normally, a bar insertion locking hole is provided in the vertical frame near the left and right sides of the surface lattice body that is installed in the sash frame so that it can be opened on both sides. The locking members are respectively inserted into the insertion locking holes of the locking pieces, and these surface lattice main bodies are fixed so that they cannot be moved from outside. As a result, the area lattice serves as a crime prevention function. If a disaster such as a fire occurs inside the room, the locking bar is moved toward the room by operating the operating means so that the tip of the locking bar is the frame body of each plane lattice main body. When pulled out from the bar insertion locking hole of, or by moving the locking member toward the indoor side by operating the operating means,
Since this locking member is pulled out from the insertion locking hole of the locking piece and the locked state is released, by moving one surface lattice main body to the other side in this state, one side of the frame body of the sash is moved. Since it is opened, it is possible for a person inside the room to escape to the outside through this open part and evacuate. As a result, a person who is inside the room at the time of a disaster such as a fire can be spared from this disaster. In this way, it is possible to escape from the indoor side to the outside without removing the surface lattice main body.
