Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a surface lattice installed on the outside of a window primarily for security purposes.

[Prior Art] Screen lattices used on the outside of windows in low-rise buildings and general residential buildings are usually installed for security purposes and are required to be robust above all else. However, recently, while there is a demand for robustness, there has also been a demand for a function that allows escape from indoors to the outside in the event of an emergency such as a fire or earthquake.

[Problem that the invention aims to solve] Therefore, in times of emergency, people are often upset, so
Opening the surface lattice through complicated operations is not enough.
The reality is that this can lead to disaster.

In view of these circumstances, the present invention is designed to be opened with a simple operation in the event of an emergency such as a fire or an earthquake, allowing escape from indoors to the outside, while maintaining its robustness during non-emergencies to achieve the purpose of crime prevention. This is an attempt to provide a surface lattice that makes it possible to

[Means for Solving the Problems] The present invention provides an inner frame that includes an outer frame that is attached to a building, and a surface lattice member that is housed within the outer frame and is configured to be slidable in the vertical direction together with the lower frame section. and a locking mechanism in which a lock pin is moved in and out of a lock hole provided in a vertical frame portion by operating a handle incorporated in the lower frame portion of the outer frame and disposed outside the lower frame portion of the outer frame. , and has a structure in which a locking mechanism for regulating the handle position is provided in the handle portion, and further, in place of the locking mechanism, a cover covering the handle is provided on the window frame side or the outer frame lower frame side. .

[Function] Therefore, when the handle is operated, the lock pin fitted into the lock hole in the lower frame portion of the outer frame comes off, the inner frame slides downward, and an opening is formed in the outer frame.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the surface lattice of the present invention includes an outer frame 4 that is attached to the outside of a building 1 such as a window frame with auxiliary members 2 and screws 3, etc.; In normal times, the inner frame 6 is equipped with a suitable surface grid member 5, and in an emergency, the required part of the inner frame 6 is slid downward to move the inner frame 6 inside the outer frame 4 as shown in FIG. It mainly consists of a lock 8 for forming an opening 7 for escape.

In addition, 11 is covered with window glass.

The inner frame 6 is divided into upper and lower parts at an arbitrary height position X, the upper part is fixed to the outer frame 4 as a fixed part 6a with screws 9 etc., and the lower part is fixed to the vertical frame part 4a of the outer frame 4 as a movable part 6b. However, it is configured to be slidable in the vertical direction. Such a slide mechanism is as shown in FIG. 3, and the inner frame movable portion 6b and the outer frame vertical beam portion 4a are configured as an engagement guide mechanism 10 of, for example, a dovetail groove type. In addition, when the inner frame movable part 6b slides, the lower frame part 4b of the outer frame 4 also slides together, and the inner frame movable part 6b is fitted with an appropriate stopper ( As shown in FIG. 5, the slide position is regulated by the slider (not shown).

Further, as shown in FIG. 4, a pin 12 projecting upward is appropriately provided at the upper end of the inner frame movable portion 6b.
is stored in the outer frame 4, the inner frame fixing part 6
It can be fitted into a fitting hole 13 provided corresponding to the lower end of a.

The details of the locking mechanism 8 are as shown in FIGS. 6 and 7. That is, lock pin storage cases 14 are fixedly installed at both ends (only the left end is shown in the figure) of the outer frame lower crosspiece 4b, and the front side of the case 14 is inserted into the case 14. A lock pin (barrel) 16 is disposed to go in and out of a lock hole 15 that penetrates and is bored at the lower end of the outer frame vertical beam 4a.
A shaft 17 whose sliding movement is guided by the rear surface of the case 14 is integrally fixed to the rear end of the lock pin 16, and a compression spring 18 is attached to the shaft 17 at a position inside the case 14.
The force of the spring 18 always applies a protruding force to the lock pin 16 in the direction of the lock hole 15. Shang 19
is closed by the auxiliary plate of lock hole 15.

Moreover, the longitudinal direction middle part-side part (window side) of the outer frame lower crosspiece part 4b
An operating handle 20 for operating the lock pin 16 in and out of the lock hole 15 is arranged, and a handle shaft 21 to which the handle 20 is fixed is rotatable within the outer frame lower crosspiece 4b. It is provided. Furthermore, a bracket 22 is fixed to the middle part of the handle shaft 21 and protrudes so as to face each other in the circumferential direction. A wire 23 is stretched between them, and by rotating the handle 20, the shaft 17 can be slid through the wire 23, and the lock pin 16 can be removed from the lock hole 15. Further, a cylinder lock 24 is incorporated into the handle shaft 21, so that the handle 20 can be moved freely by inserting a key 25, and the position of the handle 20 can be fixed by removing the key 25. In order to assemble the lock device 1B, it is convenient to have a structure in which the bottom plate portion 4b' of the outer frame lower crosspiece portion 4b can be slid in the longitudinal direction and removed as shown in FIG.

With this configuration, under normal conditions, the inner frame movable portion 6b is housed within the outer frame 4 as shown in FIG. 1, and the lock pin 16 is inserted into the lock hole 15 as shown in FIG. The position of the handle 20 is fixed in a locked state. This provides a robust structure and allows the handle 2 to be seen from the outside.
Since 0 cannot be manipulated, the purpose of crime prevention can be achieved.

On the other hand, in case of an emergency, that is, when it is necessary to escape from the room to the outside by passing through the grid, insert the key 25, which has been kept in a conspicuous place in the room in advance, into the cylinder lock 24. Rotate the handle 20 as shown in the figure. By operating this handle 20, the bracket on the handle shaft 21? 2 is displaced, the shaft 17 is pulled through the wire 23, and the lock pin 16 integrated with the shaft 17 slides toward the handle 21 shaft against the force of the spring 18. As a result, the lock pin 16 disengages from the lock hole 15, and the inner frame movable portion 6b slides downward under its own weight (or by pressing down lightly by hand) into the outer frame 4 as shown in FIG. An opening 7 is formed. Therefore, it is possible to escape from the room to the outside using this opening 7.

In the above, since the operation for forming the escape opening 7 can be performed by simply inserting the key 25 and rotating the handle 20, it can be performed in a short time and is extremely convenient and useful in an emergency. is high.

The height position X of the inner frame movable part 6b is selected depending on the size of the surface lattice itself. For example, in the case of a surface lattice compatible with a small window, the height position X is determined by the height of the inner frame 6 body. It also includes cases where

10 to 13 show another embodiment of the present invention, in which the operation of the key 25 in the previous embodiment is not necessary. That is, when the lock pin 16 is inserted into the lock hole 15 in the locked state, the handle 20 is set to be in a horizontal position, and the cover 26 is installed to cover the handle 20 in the horizontal state.
wo, the outer window glass 11 when the outer window glass 11 is closed
When the window glass 11 is closed, the cover 26 hides the handle 208, making it impossible to operate the handle 20 from the outside, and when the window glass 11 is opened, the cover 26 also hides the handle 208@. The handle 20 is exposed by moving together, and the handle 20 can be operated.

Therefore, in the case of this method, there is no need to insert the key 25 in an emergency, and the handle 20 can be operated simply by opening the window glass 11, making it possible to form the escape opening 7 extremely easily and in a short time. can do.

14 and 15 show still another embodiment of the present invention, in which the cover 26 is normally attached to the lower frame portion 4b regardless of whether the window glass 11 is opened or closed, and the cover 26 is removed in an emergency. It is made to be removable.

That is, the cover substrate 28 is fixed to the handle 20 arrangement portion of the outer frame lower crosspiece 4b, and the cover 268 is attached to the cover substrate 28.
The cover 26 is engaged so as to be slidable in the longitudinal direction, and the sliding position of the cover 26 in the left direction (window glass closing direction) in FIG. The stopper plate 30 attached to the frame 27 of the window glass 11 is configured to restrict when the window glass 11 is closed, and when the window glass 11 is closed, the cover 26 is prevented from sliding in the left and right direction. When the handle 20 is made inoperable and the window glass 11 is opened, the stopper plate 3
Since the cover 26 can be removed to the right by moving together with the window glass 11, the handle 20 can be operated.

Therefore, in the case of this method, the handle 20 can be exposed only when necessary, and since it is always covered with the cover 26, it can be prevented from being exposed to rainwater.

Note that the present invention is not limited to the above-mentioned embodiments; for example, the handle shaft 21 and the lock pin 16 may be connected by a link mechanism, and various other changes may be made without departing from the gist of the present invention. Of course, there are many things that can be added.

[Effects of the Invention] As explained above, according to the surface lattice of the present invention, the purpose of crime prevention can be achieved by maintaining a robust structure at all times, and in an emergency, an opening for escape can be formed with a simple operation. It is possible to achieve excellent effects.
