Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a surface lattice to be attached to the outside of a window, more specifically, an openable surface that can be opened and evacuated in the event of a fire, earthquake or other emergency. Regarding the lattice.

[Conventional technology]

In a normal surface lattice, a plurality of vertical ledges are attached to the upper and lower ridges to form a lattice unit, and the lattice unit is attached to the outside of the window.

Such a plane lattice is firmly fixed to the wall of the building for the purpose of crime prevention or danger prevention, and cannot be easily removed.

Therefore, in the event of an emergency such as a fire or an earthquake, it is impossible for people in the room to evacuate from the window to which the screen lattice is attached.

Therefore, as shown in Japanese Utility Model Application Laid-Open No. 58-134589, a plane lattice has been proposed in which a part of the lattice unit can be easily opened from the indoor side.

In other words, a part of the lattice unit is allowed to swing inward, the shoji of the window is opened, and a part of the lattice unit is swung inward through the opening to open a part of the surface lattice, and then the opening. Area grid that allows people to evacuate from the department.

[Problems to be Solved by the Invention]

In such a surface lattice, it is not preferable in terms of crime prevention to be able to swing a part of the lattice unit from the outdoor side to the indoor side.
A movable stopper that stops the shoji of the window at a predetermined open position is provided, and the width of the opening when stopped by the movable stopper is made narrower than the width of a part of the swinging lattice unit to make the movable stopper. Is set to a position where the movement of the shoji is not restricted, the shoji is fully opened and the width of the opening is made narrower than the width of part of the lattice unit that swings, and the movable stopper can be operated only from the indoor side. , From the indoor side, you can swing part of the lattice unit to the room side from the opening by operating the movable stopper to fully open the shoji, but from the outdoor side you can not operate the movable stopper and you can not fully open the shoji Therefore, a part of the lattice unit interferes with the shoji screen so that the lattice unit cannot swing inside.

Therefore, in order to swing a part of the lattice unit to the room side from the opening to open a part of the lattice unit, operate the movable stopper to fully open the shoji, and then raise part of the lattice unit upward. The operation procedure is very troublesome and troublesome.Therefore, in an emergency, sometimes the operation procedure may be forgotten, or the operation sequence may be incorrect so that a part of the lattice unit cannot be opened. Since it is provided on the shoji side, it is difficult to understand that it is used when opening a part of the lattice unit, and it is not preferable for a person who does not know the above-mentioned operation procedure because the part of the lattice unit cannot be opened.

Further, the movable stopper prevents the shoji from being fully opened, and in order to fully open the shoji in normal times, the movable stopper must be operated, and it is troublesome to fully open the shoji in normal times.

Therefore, it is an object of the present invention to provide a surface grating capable of solving the above problems.

And Shimotsuki 13 are now in a free state, and under that condition Shimo Yokoso
By moving the indoor unit 15 upward to the indoor side, the movable lattice unit can be swung upwards to the indoor side to open a part of the lattice unit D, and in an emergency, people in the room can evacuate to the outside.

In addition, the shoji screen can be fully opened without any operation during normal operation.

If the sixth shoji screen is opened and the window 6 is opened, the movable lattice unit can be swung upward in the room through the opening 6a.

In addition, when the movable lattice unit is rocked upward in the room to open a part of the lattice unit, the holding mechanism 40 moves the upper horizontal shaft.
The movable grid unit can be held so that the movable grid unit does not swing downward due to its own weight by holding 14 on the upper casing 11.

〔The invention's effect〕

When the grips 26, 56 of the engaging member 22 of the lock mechanism 20 are held and detached from the receiving member 23, the lower horizontal shaft 15 and the lower horizontal shaft 13 are in a free state, and the lower horizontal shaft 15 is moved upward in the room as it is. By moving, the movable lattice unit can be swung upwards toward the inside of the room to open a part of the lattice unit D, and a person inside the room can evacuate to the outside in an emergency.

Therefore, the engaging member 22 of the lock mechanism 20 is locked by the handles 26, 56.
After unlocking and holding the lock, you can move it upward without changing it, and the operation procedure is extremely simple and easy, and you can not forget the operation procedure in an emergency or swing the movable grid unit by mistake in the operation sequence. In addition, the lock mechanism 20 is provided on the lower horizontal shaft 15 of the movable grid unit and is easy to understand when used when rocking the movable grid unit, and even a person who does not know the above operation procedure can rock the movable grid unit. You can open a part of the lattice unit.

Further, since the opening stroke of the shoji screen is not restricted at all, the shoji screen can be fully opened without any operation during normal operation, which facilitates the operation.

Further, since the width of the movable lattice unit is narrower than the width of the opening 6a of the window 6, if the shoji of the window 6 is opened and the window 6 is opened, the movable lattice unit swings upward from the inside of the opening 6a. It is safe because it does not require dangerous operations such as breaking the glass of the shoji.

In addition, when the upper horizontal shaft 14 is rotated around the upper horizontal shaft 11 toward the upper side of the room by a predetermined angle, the upper horizontal shaft 14 is prevented from being rotated downward by the weight of the movable shoji unit. By providing a holding mechanism 40 for holding the upper grid 11 on the upper shell 11, when the movable grid unit is rocked upward in the room to open a part of the grid unit, the upper horizontal shell 14 is held by the holding mechanism 40 on the upper shell 11. Since the movable lattice unit can be held so as not to swing downward by the weight of the movable lattice unit under its own weight, it is not necessary to hold the movable lattice unit by hand when escaping in an emergency, and the movable lattice unit can be easily escaped.
