[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a handrail which is attached to the outside of a window glass in a window part mainly for crime prevention and a handrail provided along the edge of a rooftop of a building for the purpose of preventing a fall accident or the like.

[0002]

[Prior art]

 Generally, outside the window of a building such as a house, a plane lattice (100) as shown in FIG. 20 is provided for the purpose of crime prevention or decoration. In order to attach the conventional surface lattice (100), for example, a mounting metal fitting (103) screwed or welded to a horizontal lattice bar (102) connecting a plurality of vertical lattice bars (101) is used to attach the sash. A means to fix the duck attached to the outside with a screw (104) is used. That is, it is firmly fixed to the outside of the window so that it cannot be easily removed. On the other hand, the handrail for safety on the roof of the building is firmly installed by welding.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional surface lattice (100) is effective for crime prevention or decoration, but conversely, a person left behind in a room when a disaster such as a fire tries to blame the outside from the window. In this case, since the area lattice (100) is attached to the outside of the window in a fixed state, it is impossible to escape from the window to the outside and blame it. I sometimes wore it. In addition, when trying to rescue a person accused on the roof of a building due to a fire, etc. by a ladder car, especially for the elderly and children, it is difficult to get over the handrail, and it takes time to rescue and sometimes rescue. There is a fear that things that cannot be done will occur.

Therefore, the present invention provides a surface lattice / handrail structure that can be easily removed from the indoor side or the front side in the event of a disaster such as a fire and can be easily evacuated to the outside. It is a specific subject.

[0005]

[Means for Solving the Problems]

 In this invention, as a technical means for achieving the above-mentioned subject, the surface lattice / handrail structure is configured as follows. That is, in the structure of a surface lattice / handrail provided on the outside of the window of the building or on the edge of the roof, the surface lattice main body or handrail main body with a rectangular outer shape and the rotary operation handle inside or inside On the other hand, the attachment / detachment bar protruding in the orthogonal direction is rotatably attached with both ends thereof protruding sideways, and the engagement members are integrally provided at both ends of the attachment / detachment bar. The surface lattice main body or the handrail main body is locked by rotating the sash or the pillar by inserting the engaging member in a fixed receiver provided on the sash or the pillar in a specific direction and then rotating the engaging member. It is characterized in that the member is formed in such a shape that it can be engaged and disengaged only when it opposes the fixed receiver in a specific direction by rotation of the attachment / detachment bar.

[0006] Furthermore, an engaging pin is provided on a frame or a terminal crosspiece in a direction orthogonal to the attaching / detaching bar of the surface lattice main body so as to project outward, and the engaging pin engages with the sash. It is inserted into and removed from the hole.

Further, the length of the rotary operation handle is made longer than the distance between the surface lattice main body attached to the sash and the window glass inside thereof, and the sash frame chamber is located from the rotation center of the rotary operation handle. The distance to the outermost edge is shortened.

[0008]

[Action]

 When attaching the surface lattice main body or the handrail, rotate the attachment / detachment bar with the rotating handle to orient the engaging member in a specific direction so that the engaging member can be engaged with the fixed receiving member. When the attachment / detachment bar is rotated by the rotation operation handle after that, the rotation operation handle can rotate without hitting the sash frame. In contrast to the specified orientation, the main surface of the lattice or the handrail is attached to the sash or pillar without falling off. Here, in the case of a surface lattice, if the rotation operating handle is made longer than the distance between the surface lattice main body attached to the sash and the window glass inside this, the rotation operating handle will contact the window glass. It does not rotate more than a certain angle, the engaging member does not have a specific orientation that can be engaged with and disengaged from the fixed receiver, and the handle for rotation can only be rotated inward, so it can be operated from the outside. There is no fear of being involved in crime, and it can fully fulfill the role of crime prevention.

In addition, when a disaster such as a fire occurs, the window glass is removed from the room or the window glass is broken, and the handle for rotation is turned to bring the engaging member into a specific direction in which it can be engaged with and disengaged from the fixed receiver. When fitted together, the engagement between the engagement member and the fixed receiver can be released, and the main body of the surface lattice can be easily removed, and it is possible to escape to the place where the surface lattice was located and escape to the outdoors. .
