JPH11193676A - Face lattice provided with opening/closing mechanism - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent illegal invasion from the outside by providing face lattice main body constituted of vertical bars, horizontal frames, and rings, and an upper horizontal bar detachably holding the upper part of the face lattice while setting a lower horizontal bar rotationally movably holding the lower part of the face lattice main body, and providing a warning device on the upper horizontal bar. SOLUTION: At opening a face lattice, a thumbscrew 25 threadedly provided on one end of an upper horizontal bar 2 is detached or loosened, a fastening bolt on the center part of the upper horizontal bar 2 is loosened, and the upper horizontal bar 2 is separated from the face lattice 1a. Next, when the optional position of vertical bars 1a is pushed outward by hand or the like, the face latice main body 1a is rotated outward centering around the axis of a lower horizontal bar, and the hole face of the face lattice is opened. Even if an illegal invader from the outside intends to loosen the fastening bolt, the fastening bolt is positioned in a receiving box, and it is difficult to loosen from the outside. Even if it can be loosened, a warning device 41 is actuated to generate alarm. Hence an illegal invader can be previously prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface grid suitable for evacuation and crime prevention in a disaster or the like.

[0002]

2. Description of the Related Art A conventional screen grid has a main purpose of crime prevention, and is made so that an illegal intruder from outside cannot remove it. However, due to changes in architectural styles, in recent years, it has been required that the grid can be removed with a simple operation for emergency escape in the event of a fire or earthquake, and that it cannot be removed from the outside illegally. Became. To meet such demands, Japanese Utility Model Publication No. 6-19754 and Japanese Patent Application Laid-Open No. 8-303145 have been disclosed.

[0003]

SUMMARY OF THE INVENTION
The structure disclosed in Japanese Patent No. 754 is a surface grid used for construction or the like, particularly a surface grid configured so that the upper end of the surface grid is horizontally supported and the lower end of the surface grid can be pushed outward. The upper and lower ribs projecting inwardly from the upper and lower walls of the lower horizontal rail are sandwiched between the outer and inner fixing plates at substantially the center in the longitudinal direction, so that the outer and inner fixing plates are held inside the lower horizontal rail. The rotating plate is placed outside the outer fixing plate, and the rotating shaft is projected inward from the center of the rotating plate. A rod is pivotally mounted on the pivot shaft so that it can be turned upside down, and on a plate symmetrical with respect to the center of the pivot plate,
The inner ends of the left and right sliding rods are each axially mounted, and the outer ends of the sliding rods are axially mounted on the right and left sliding rods, respectively. The lower grid metal fixture fixed to the building frame has a hook claw protruding outward from its face plate, and a hook groove provided on the hook claw engages with a hook hole of the sliding plate. As a result, the lower horizontal rail of the surface lattice and the lower lattice stopper are engaged and held, the push rod is twisted, the rotating plate is rotated, the sliding plate is pulled, and the latch hole and the latch groove are formed. By releasing the engagement of the lower grid and the lower grid fastener, the outer cylinder is rotatably fitted to the rotating rod. However, there is a problem that escape in an emergency is difficult due to insufficient openness of the plane grid. In addition, the surface grid opening / closing mechanism is in the way, and cannot be installed outside the screen door or the glass door.

Further, the structure disclosed in Japanese Patent Application Laid-Open No. 8-303145 discloses a surface lattice in which a surface lattice body is openably and closably mounted in a surrounding frame composed of upper and lower frames and left and right vertical frames.
The surface lattice body has engaging pins or guide grooves at upper and lower ends of one side, while the surface lattice body has guide grooves or engaging pins at one side of the upper and lower frames, and the surface lattice body has a longitudinal direction with respect to the upper and lower frames. , And the surface lattice body is provided so as to rotate in a direction perpendicular to the longitudinal direction of the upper and lower frames with one side as a fulcrum. However, because of the structure in which the surface lattice body is incorporated in the surrounding frame, the structure is complicated and the cost is high. Further, when the surface grid is partially damaged or deformed due to an earthquake or the like, it is extremely difficult to push the surface grid body out of the surrounding frame.
