Description

Description: FIELD OF THE INVENTION The present invention relates to a surface lattice to be installed on the outside of a window, and more particularly to an area lattice to be installed on the outside of a window facing a common corridor of an apartment house or a school corridor.

[Conventional technology]

The area lattice shown in Japanese Utility Model Laid-Open No. 58-134589 is known.

That is, a part of the surface lattice main body fixed to the outdoor side of the window is opened and closed to form an opening / closing portion, and a fixing metal fitting for fixing the opening / closing portion to the surface lattice main body is provided to regulate the opening position of the shoji constituting the window. A stopper is provided, and the width of the opening and closing part is narrower than the width of the opening when the shoji is fully opened, and wider than the opening when it is regulated by the stopper. This is a surface lattice in which the opening / closing portion of the surface lattice main body can be opened by releasing the fixing of the opening / closing portion with a metal fitting.

With this area lattice, you can evacuate from the area by opening part of the area lattice in the event of a fire, earthquake or other emergency.

[Problems to be Solved by the Invention]

With such a surface lattice, in order to open the opening / closing part of the surface lattice main body, the stopper that regulates the opening position of the shoji is operated to fully open the shoji, and the fixing metal fitting is operated to release the fixation of the opening / closing part. It is necessary to perform the opening operation, which is very troublesome and cannot be opened by a person who does not know the aforementioned troublesome opening operation.

Because of this, in the event of an emergency, it would be necessary to use a surface lattice in a place where a large number of unspecified people or children who do not know the aforementioned troublesome opening and closing operations pass through, such as in corridors for apartments and schools. Sometimes it can't be released.

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

[Means and Actions for Solving the Problems]

And becomes a long member having a hollow shape 31e and a downward concave portion 31f in a sectional shape, and the lower mounting frame 32 has a horizontal plate 32a, an intermediate vertical plate 32b, and an outdoor side vertical plate 32c, and has a sectional shape having an upward concave portion 32d. The downwardly extending hook piece 33 is integrally provided on the upper part of the outdoor side vertical plate 32c to form the locking portion 34.

The upper bar 11 is one side of the horizontal plate 1a and the other side vertical plates 11b, 11c and has a substantially U-shaped cross section, and is fitted in the downward recess 31f of the upper mounting frame 31 by the opening prevention mechanism 35. It is held so that it does not fall downward.

The lower bar 13 has a substantially U-shaped cross section in one side with the horizontal plate 13a and the other vertical plates 13b and 13c, and an upward hook piece 36 is integrally provided on the other vertical plate 13c. The stopper 37 is configured, and the lower rail 13 is pushed up by the push-up mechanism 38 so that the locked portion 37 is the locking portion of the lower mounting frame 32.
The push-up mechanism 38 connects the base portion 39 and the movable portion 40 slidably up and down, and biases the movable portion 40 upward by a spring 41. Side plate 32 of mounting frame 32
The movable portion 40 is attached to a and the movable portion 40 is in contact with the lateral plate 13a of the lower rail 13.

The release blocking mechanism 35 includes the receiving member 42, the engaging member 43, and the sliding plate 4.

Is screwed to the sliding plate 44 and has an engaging portion 43a, and the sliding plate 44 is slidable along a guide plate 47 screwed to the connecting lateral plate 31d of the upper mounting frame 31 and is guided. A long guide hole 49 facing the slider 48 provided on the plate 47 is formed, and the engaging member 43 is formed.
Is projected toward the upper crosspiece 11 side from the notched elongated hole 47a of the guide plate 47 and the notched elongated hole 50 of the connecting lateral plate 31d.

The oscillating plate 44 is supported by the connecting horizontal plate 31d so as to be horizontally oscillatable by a support shaft 51 and a block 52, and a pin 54 provided on the sliding plate 44 is engaged with a notch 53 formed at one end thereof. And an engaging recess 55 is formed at the other end, and the engaging recess 55 has a substantially v shape, the cam 46 is screwed to the upper part of the shoji 5 on the outdoor side, and the end has a substantially mountain shape. It is shaped so that it can be engaged with and disengaged from the engaging recess 55, and when the shoji 5 is closed, the cam 46 engages with the engaging recess 55 as shown in FIG.
Is swung in the direction of the arrow, whereby the sliding plate 44 is slid in the direction of the arrow via the pin 54 engaged with the notch recess 53, and the engaging portion 43a of the engaging member 43 receives the receiving portion of the receiving member 42. As shown in FIG. 3, the upper crosspiece 11 is engaged with and held by the upper mounting frame 31 and the open portion D ₁ of the lattice unit D is supported so as not to move downward.

〔The invention's effect〕

When the shoji 5 is released, the locking member 43 moves to a position where it is separated from the receiving member 42 and the open portion D ₁ can be moved downward. Therefore, the open portion D ₁ is moved downward against the push-up mechanism 38. Then, the opening portion D ₁ can be removed by pulling it toward the inside of the room to open a part of the lattice unit D.

Therefore, a part of the lattice unit D can be opened by a simple operation of opening the shoji 5 to lower the open portion D ₁ and pulling it, and the open portion D ₁ is held at the upper position by the push-up mechanism 38. When opening the shoji screen 5, this open part D ₁
It will not come off unless you pull it.

Further, when the shoji 5 is closed, the locking member 43 moves to the engaging position and engages with the receiving member 42 so that the open portion D ₁ cannot move downward, which is preferable for crime prevention.
