Description

  This invention is installed outside the building with respect to the window of the building, etc., and not only adjusts the ventilation and lighting in the room, but also prevents the intrusion of suspicious people from the outside and opens it when a fire etc. occurs. The present invention relates to a louvered surface lattice that can be escaped.

  In general, a conventional escape plane lattice attached to a building window or the like has two sets of obstacles for opening and closing the outer frame in an outer frame fixed to the outside of the building window. The two types of shojis are incorporated so that they can be moved in a movable manner.The two shoji bodies are formed by fixing the crosspieces in the shoji frame at regular intervals. Ventilation and daylighting can be obtained, and safety during going out and sleeping is ensured.When escaped, the locking mechanism is unlocked, while the shoji body is moved to the open position, and the inner peripheral opening of the outer frame is halved. It is structured so that it can escape from the open part to the outside.

  In addition, apart from the escape lattice by the shoji frame fixed with the above-mentioned crosspieces fixed at regular intervals, a large number of louver blades are rotatably mounted in the shoji frame in parallel with regular intervals. There has also been proposed a louver plane lattice fixed on the outdoor side of a window, and each louver vane plate can be opened and closed in synchronization by an operating portion provided on a shoji frame, thereby adjusting ventilation and lighting.

  By the way, the escape face lattice as described above has a role of crime prevention to fix the two shoji bodies normally closed by the locking mechanism and prevent intrusion from the outside. There is a risk that an operation of unlocking the locking means by inserting a hand or tool from the outside of the room from the gap or the gap between the louver slats will cause a risk that the escape face grid has sufficient security function There is a problem that it cannot be obtained.

  Also, the former face grid with the shoji frame, which is fixed at regular intervals, has the inconvenience that ventilation and lighting cannot be adjusted, whereas the latter louver face grid is a louver blade. By adjusting the angle, there is an advantage that ventilation and daylighting can be adjusted freely from complete sealing.

  Therefore, an object of the present invention is to provide an escape louver surface lattice that can sufficiently secure a crime prevention function by taking advantage of the louver surface lattice and making it impossible to unlock from the outside. .

  In order to solve the problems as described above, the invention of claim 1 is incorporated in an outer frame fixed to a building and an inner peripheral opening of the outer frame in the outer frame, and at least one of them can be opened and closed. The outer frame or the louver obstacle is provided with a locking mechanism capable of fixing and releasing the louver obstacle in a closed position with respect to the outer frame or the other louver obstacle, Covering the louver block that moves to open and close so that the locking mechanism cannot be operated when the louver block of the louver block is in a closed position with respect to the outer frame and the louver blade of the louver block is in an open phase. A configuration in which a cover member that opens so that the locking mechanism can be operated in a state in phase is employed.

  Here, as the locking mechanism, a crescent lock, a push lock, a lever-type lock, a bar-type lock, or the like is used, and these locking mechanisms are accommodated in a vertical shaft of the outer frame, or can be opened and closed. The louver shoddle is attached to the louver shoddle frame, and the louver shodder that can be opened and closed is locked in the closed position, so that the louver shodder cannot be opened and the louver blade is in the open phase. On the other hand, the vertical wall, the opening surface facing the indoor side, and the surface facing the indoor side of the locking mechanism are concealed so that the locking mechanism cannot be unlocked from both inside and outside the room.

  In addition, when the louver blade plate of the louver shoji frame that can be opened and closed in the closed position is set to the closed phase, the covering member also moves simultaneously with the louver blade plate so that the surface facing the downside or the indoor side of the locking mechanism When the door is opened and the unlocking operation of the locking mechanism can be performed from the indoor side, and the louver shoji frame that can be opened and closed is moved to the open position, it is possible to escape from the window.

  The invention according to claim 2 employs a configuration in which the outer frame fixed to the building is fixed to the outside of the outdoor room with respect to a sash attached to the opening of the building.

  The invention of claim 3 employs a configuration in which the outer frame fixed to the building is fixed to the building frame at a position outside the room with respect to the sash attached to the opening of the building.

  According to the invention of claim 4, the louver body can be pushed out or pushed up to the outdoor side from a state parallel to the sash with a mounting bracket at a position on the outdoor side with respect to the sash attached to the opening of the building. A locking mechanism is provided between the louver obstacle body and the mounting bracket so that the louver obstacle body in a closed position can be fixed to and released from the mounting bracket, and the louver obstacle body is closed to the sash. And the louver blade of the louver body is covered so that the locking mechanism cannot be operated in the open phase, and the louver blade is opened so that the locking mechanism can be operated in the closed phase. A configuration in which members are provided is adopted.

  According to a fifth aspect of the present invention, the louver shoji body is mounted in a shoji frame so that a large number of louver vanes can be rotated in a parallel arrangement at regular intervals, and the louver vanes are adjacent to each other in a closed phase. The louver blade plates are configured to be opened and closed in synchronization with each other by an operating portion provided on the shoji frame so that the end portions of the lap wrap each other and form a gap between adjacent louver blade plates in the open phase. Is adopted.

  Here, the open / close movement of the louver body with respect to the outer frame can be performed by using a two-rail type sliding structure provided on the outer frame or two louver bodies arranged on a single rail. On the other hand, adopting a sliding structure that moves so that it overlaps the room side of the louvered body, unlocks the louvered body in the closed position and moves it to the other side, opening the half in the outer frame and from the room Allows escape.

  In addition, since the locking mechanism is concealed by a covering member with the louver blade plate in the open phase, the locking mechanism cannot be operated even if a hand or a tool is inserted between the louver blade plates from the outdoor side, and the louver obstacle Since the body cannot be opened, the louver blades arranged at regular intervals prevent intrusion from the outside.

  In addition, when trying to operate the locking mechanism, the louver blade must be in the closed phase, so when the louver blade is in the closed phase, there is no gap between the louver blades where a hand can be inserted from the outside. Therefore, the locking mechanism cannot be unlocked from the outdoor side, and when the louver blade plate is in the closed phase, there is no concealment of the locking mechanism by the covering member, and the locking mechanism is unlocked from the indoor side, If you open the louver shoji, you can escape from the room.

  According to the present invention, since the two louver obstacles can be opened and closed to form a plane lattice, the advantage of the louver plane lattice is obtained by fixing and arranging the louver plane on the outdoor side of the window, and by adjusting the angle of the louver blade plate, The locking mechanism that can freely adjust the ventilation and lighting in the fully closed state and ventilation, and the locking mechanism to fix the two louvered obstacles, the operating surface side is concealed by the cover member in the ventilation and lighting conditions of the louver blades, either inside or outside Because the door cannot be unlocked, the two louver doors cannot be opened.This prevents intrusion from the outside and unlocks the locking mechanism from the indoor side only when the louver blade is in the closed phase. The louver shoji can be opened, and the security function can be fully achieved by making it impossible to unlock from the outside while maintaining the escape function of the two louver shojis. It can be coercive.

  In addition, if the louver plane lattice is fixed to the exterior of the sash attached to the outside of the building or fixed to the building frame, the window becomes a double structure inside and outside the sash and louver plane lattice. Security functions can be added while maintaining ventilation and daylighting functions, and in an emergency, two louver doors can be opened to escape from the indoor side, always unlocking from the outside. By eliminating, it can contribute to the improvement of crime prevention while maintaining the escape function with respect to the existing window.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The louvered surface lattice 1 of the first embodiment shown in FIGS. 1A to 1C is an example in which the sash b attached to the opening serving as the window of the building housing a is fixed to the outside of the room by retrofitting. An L-shaped mounting bracket is fitted to both sides of the outdoor side of the sash b, and the bent end of the L-shaped mounting bracket is fitted into the outer blade of the sash b and fixed. The outer frame 2 is fixed, and two louver shoji bodies 3 and 3 are incorporated in the outer frame 2 so as to be able to move in a sliding manner, and in the vertical rail 2a of the outer frame 2 by an operation from the indoor side, A locking mechanism 4 is provided that can fix and release the louver obstacles 3, 3 in the closed position with respect to the outer frame 2.

  The louver shoji bodies 3 and 3 have a size that allows the inside of the outer frame 2 to be fully closed with two louver shoji bodies 3 and 3. Thus, a rectangular shoji frame 5 that can be opened and closed in the lateral direction in the outer frame 2 and a large number of louver blades 6 attached in the shoji frame 5 are formed.

  In the first embodiment, an example in which the louver blade plates 6 are arranged vertically is shown, and each louver blade plate 6 is formed as a belt plate having a length that fits within a predetermined horizontal width and vertical vertical width in the shoji frame 5. The center shaft 7 that protrudes from the center in the width direction at both ends in the axial direction is supported by the upper and lower rails of the shoji frame 5 so as to be rotatable around the shaft 7, and each louver blade 6 is a plate. When the surface is in a closed phase along the opening / closing direction of the shoji frame 5, the ends of the louver blades 6 adjacent to the left and right wrap around each other, and in an open phase other than the closing phase along the opening / closing direction of the shoji frame 5, The louver blades 6 are attached to the left and right at regular intervals so as to form a gap between the adjacent louver blades 6, and each louver blade 6 is housed in the upper and lower rails of the shoji frame 5 as is well known. Rotating synchronously using a rack and pinion mechanism or link mechanism Are interlocked, by sliding the operating portion provided on a surface facing the interior side of the vertical bar of the sash frame 5 in the vertical or rotated, are formed a louvers slats 6 at the same time so as to opened and closed.

  Therefore, when each louver blade plate 6 is in a closed phase along the opening / closing direction of the shoji frame 5, the end portions on both sides wrap to each other to be in a fully closed shutter state, and ventilation and lighting are shut off, and at the same time from the outdoor side. When it is impossible to insert a hand and each louver blade plate 6 is oriented perpendicularly to the opening / closing direction of the shoji frame 5, an open phase is formed in which a gap is formed between both louver blade plates 6, and each louver blade plate By changing the opening angle of 6, ventilation and lighting can be adjusted.

  The louver blade 6 is formed using various metals such as aluminum and hard resin, and the end of each louver blade 6 in the width direction overlaps with the adjacent louver blade 6 when closed. The surface can be provided with a sealing means for sealing the overlapping surface of both.

  A locking mechanism 4 is provided in the vertical beam 2a of the outer frame 2 so that the louver shoji 3 and 3 in the closed position can be fixed and opened with respect to the outer frame 2 by operation from the indoor side, and the louver blade body 6, the locking mechanism 4 cannot be operated as shown in FIG. 2A when the louver obstacles 3 and 3 are in the closed position with respect to the outer frame 2 and the louver blade body 6 is in the open phase. A cover member 8 for opening and closing the opening portion of the vertical beam 2a is provided so as to cover the opening portion facing the room side of the vertical beam 2a and to operate the locking mechanism 4 by setting the louver blade 6 to the open phase. It has been.

  The covering member 8 may be a short member that covers only a portion of the locking mechanism 4 or a long member that covers the entire vertical length of the opening of the vertical rail 2a.

  The opening / closing movement of the two louver obstacles 3 and 3 relative to the outer frame 2 can be performed by using a two-rail type sliding structure provided on the upper and lower sides of the outer frame 2 or two louver obstacles 3 on one rail. 3 can be arranged in the same plane, and when the door is opened, a sliding structure can be adopted in which one louver body 3 is moved so as to overlap the indoor side of the other louver body 3, and one louver body 3 is placed in the open position. When moved, substantially half of the inner peripheral opening of the outer frame 2 can be opened.

  The outer frame 2 is attached to the outdoor side of the sash b fixed to the window hole of the building frame using a mounting bracket, by assembling the vertical rods 2a on both sides and the upper and lower horizontal rails into a rectangular frame shape.

  The locking mechanism 4 can use a mechanism such as a crescent lock, a push lock, a lever-type lock, a bar-type lock, or a rotation method using a gear. The lock mechanism main body is housed in the vertical beam 2a of the outer frame 2, for example The louver obstacle 3, 3 is engaged with the outer frame 2 by engaging the locking member provided on a part of the louver obstacle 3, 3 in the closed position with the locking mechanism body in the locking position. It can be fixed.
