Description

[Detailed description of the invention] This invention relates to the improvement of window lattices.More specifically, the security lattice installed on the window can be unlocked by opening the sliding door fitted into the sash from inside the room as necessary. To provide an opening/closing window lattice which can be opened around a bearing part by doing so.

Generally, window grilles are installed to cover the entire window from the outside and are effective for crime prevention.

Therefore, although it is perfect for crime prevention, it is inconvenient in the event of an emergency, such as a fire outbreak, because it is impossible to escape and evacuate through the window by closing the window.

In view of the above points, the present invention is intended to deal with these problems, and is designed to be able to be opened and closed as needed.

An embodiment of the operable window lattice according to the present invention will be described in detail below with reference to the drawings.

1 is a window frame, and this window frame 1 has a sliding door 2 that can be opened and closed.

Further, a lattice body 3 is fitted into the window frame 1.

The lattice body 3 is composed of a large number of vertical rods 4 and a plurality of horizontal rods 5.
are connected to form a lattice.

A bearing fitting 7 is attached to the upper side of the lattice body 3 so as to face the wall of the window frame 1 or the upper part of the vertical frame 1'.
Insert the nut 8 into the screw 5' provided at the end of the horizontal rod 5.
screw them together, open the split groove 9 at the end of the horizontal rod 5, and tighten the nut 8.
The grid body 3 is supported by a bearing fitting 7 so as to be able to swing around the horizontal rods 5 without loosening.

The lower end of each vertical rod 4 of the lattice body 3 is bent inward in an L shape, and the proximal end of the locking rod 10, which has a notched engagement groove 10', is integrally attached to the tip of the bent portion. It is fitted so that.

An insertion hole 13 bored in the hollow receiving member 12 is provided at a position facing the locking rod 10.

The receiving member 12 is supported at both ends by fixing fittings 11 mounted opposite to the vertical frame 1'.

Furthermore, a locking plate 14 that engages with the engagement groove 10' of the locking rod 10 inserted through the insertion hole 13 is built into the receiving member 12 so as to be movable in the lateral direction, with both ends supported vertically. Furthermore, this locking plate 14 is provided with groove wheels 16 as appropriate for smooth movement.

Further, the locking plate 14 is connected to the tip operating portion 15' of an L-shaped operating lever 15 provided with a bent portion pivoted on the indoor side of the receiving member 12, and is locked by swinging the operating lever 15 from side to side. The plate 14 is moved, and this movement engages and disengages the locking plate 14 from the engagement groove 10' provided at the tip of the locking rod 10.

The locking plate 14 is provided with a plurality of notched recesses 14' at the same pitch as the vertical rods 4, and when the recesses 14' and the locking rods 10 are aligned, the locking of the lattice body 3 is released and the locking plate 14 When the inner edge 14' of the recess moves and the inner edge 14' of the recess fits into the engagement groove 10', the locked state is achieved.

The operating lever 15 has the above-mentioned bent portion pivoted on the receiving member 12, and is provided in a position where the end of the operating lever 15 hits the sliding door and is prevented from swinging when the sliding door 2 is closed, thereby maintaining the locked state. When the sliding door 2 is open, it can be locked and unlocked.

As is clear from the above configuration, the present invention connects the upper end to the bearing fitting 7.
The locking rod 10 is inserted into the receiving member 12 through the insertion hole 13 of the receiving member 12, which is opposite to the locking rod 10 provided integrally at the lower part of the vertical rod 4 of the lattice body 3 which is pivotally supported, and the sliding door 2 is opened. At this position, the actuating part 15 is connected to the locking plate 14 by swinging the operating lever 15, which is provided with a bent part supported on the indoor side of the receiving member 12.
When the locking plate 14 is moved through the locking plate 14 and the inner edge 14'' of the recess provided on the locking plate 14 is fitted into the engagement groove 10' of the locking rod 10, the locking rod 10 is locked with the locking plate 14. This prevents removal and locks the door.

Therefore, when the sliding door 2 is closed in this state, the end of the operating lever 15 hits the sliding door and is prevented from rotating, thus maintaining the locked state and serving as a security measure.

Furthermore, when opening the lattice body 3 as required for evacuation, etc., when the sliding door 2 is opened and the operating lever 15 is swung, the locking plate 14 in the receiving member 12 moves in the opposite direction and locks the locking rod 10. Matching groove 1
Since the engagement with 0' is released, the lattice body 3 can be opened by swinging around the bearing fitting 7, and it is possible to easily evacuate through the window, which is effective in the event of a disaster.

Further, the vertical rods 4 of the lattice body 3 are provided with locking rods 10 having engagement grooves 10' at each tip, which are inserted through insertion holes 13 drilled in the receiving member 12, and locking rods 10 that move within the receiving member 12 are provided. This is reliable because the inner edge 14'' of the recessed portion of the plate 14 and the engaging groove 10'' are all engaged and locked at once.

Furthermore, the recess 14 of the locking plate 14 can be freely provided in accordance with the position of the vertical rod 4, and since both ends are supported vertically, the locking plate 14 can move smoothly.

Also, if the lattice body 3 is supported in an open state with a support rod, etc.
It is convenient to attach a cover over the lattice body 3 so that it can be used as a field fence.
