Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an opening/closing device for a screen 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 outdoors in the event of an emergency such as a fire or earthquake.

[Problem that the invention aims to solve] However, in times of emergency, people are often distracted, and opening the grid using complicated operations may not be enough in time, which could lead to a disaster. This is the reality.

In view of these circumstances, the present invention is designed to open with a simple operation in the event of an emergency such as a fire or earthquake, allowing escape from indoors to outdoors, and also ensures promptness and safety during evacuation. In addition, it is an object of the present invention to provide an opening/closing device for a panel lattice which maintains robustness, achieves the purpose of crime prevention, and can be easily applied to existing windows.

[Means for Solving the Problems] The present invention includes a cylindrical case that rotatably incorporates an operating shaft having a rotary operating section at the indoor end, and a peripheral wall of the case at the end opposite to the rotating operating section. To,
A locking device having a long hole drilled from the top position to the side position, and a lock pin provided on the operation shaft passing through the long hole and protruding outside the case, is attached to the lower building of the lower frame part of the window frame. A lock hole is formed in the lower side of the face grating to be inserted and fixed into a hole formed in the wall part and to engage with the lock pin when the lock pin protrudes upward from the case. A support for supporting the upper side is provided at the top,
Moreover, a locking mechanism is provided between the screen grid and the window frame to restrict the falling position when the screen grid is detached.

[Function] Therefore, when the rotary operation part is operated, the lock pin rotates through the rotation of the operation shaft and is removed from the lock hole, so that the surface grating is easily removed from the mounting position and is also positioned by the locking mechanism. Fall down to where it is. In addition, installation of grids on existing windows,
It can be easily implemented without complicating the structure.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

In FIGS. 1 to 3, 1 is formed into a rectangle including an upper side 1a, a lower side 1b, and left and right side parts 1c, 1c, and a lattice member 1 is placed in the rectangular space as appropriate.
2 is a glass door; 3 is a window frame pre-installed in a window opening 5 formed in the building wall 4 to hold the glass door 2; 6 is a lower frame of the window frame 3; A draining plate 7 connected to the part 3a is a device for attaching and detaching the surface lattice 1 by inserting and fixing it into a pre-formed or newly formed hole 7' in the building wall part 4, as shown in FIG. The figure shows a state in which the grid 1 is placed in a window opening 5 so as to fit within a wall 4 of a building.

The locking device 7 has an operation knob 8 on the indoor end.
An operating shaft 9 having a cylindrical case 10 is rotatably housed in the cylindrical case 10, and a long hole 11 is bored around the end of the case 10 on the side opposite to the knob 8 from the top position to the side position, A lock pin 12 that penetrates the elongated hole 11 and protrudes to the outside of the case 10 is provided on the operating shaft 9 by, for example, a screw-in method. With the lock pin 12 removed, the lock pin 12 is inserted and fixed into the hole 7' which is provided to the lower part of the drain plate 6. In addition, a through hole 15 for allowing rotation of the lock pin 12 is formed in the draining plate 6 located above the elongated hole 11 formed in the case 10, and a through hole 15 is formed at a position corresponding to the through hole 15. A storage groove 16 that similarly allows the lock pin 12 to rotate and stores the lock pin 12 in a lateral position is recessed in the building wall 4, and these through holes 15 and storage grooves 1
Using the space 6, the lock pin 12 is screwed into the operating shaft 9 and fixed.

A lock hole 17 is provided on the lower surface of the lower side portion 1b of the surface grating 1 at a position corresponding to the through hole 15, and when the lock pin 12 protrudes above the draining plate 6, the lock hole 17 and the lock pin 12 are connected to each other. A suitable number of locking pins 18 are formed on the upper surface of the upper side portion 1a, and a locking hole slightly larger than the locking pin 18 is formed so that the locking pin 18 can be removably locked. A required number of supports 20 having 19 are attached to the upper frame part 3b of the window frame 3 so as to accommodate and support the surface lattice 1 within the window opening 5 of the building wall part 4. In addition, the state in which the surface grid 1 is attached to the opening 5,
That is, when the locking pin 18 is inserted into the locking hole 19 and the locking pin 12 and the locking hole 17 are engaged, a required gap S is formed between the support 20 and the upper side 1a of the surface grid 1. to be done.

Furthermore, a fourth
As shown in the figure, a guide link 22 having a guide groove 21 in the longitudinal direction (vertical direction) is arranged between the side part 1c of the grid 1 and the building wall part 4 forming the side edge of the window opening 5. The upper end of the guide link 22 is rotatably attached to the building wall 4 with a mounting pin 23, and the guide pin 24 is fixed to the side portion 1c by loosely fitting it into the guide groove 21 so as not to come off. This constitutes a locking mechanism for the surface grating 1.

Because of this configuration, normally, as shown in FIG.
8 into the locking hole 19, and the locking pin 12 is engaged with the locking hole 17 to be in a locked state.
Although the locking device 7 is provided at only one location in the drawing, it may be provided at multiple locations. As a result, the screen grid 1 has a robust structure, and since the knob 8 cannot be operated from the outside 14 side, the purpose of crime prevention can be achieved.

On the other hand, in the event of an emergency, that is, when it is necessary to escape from the indoor 13 side through the surface grid 1 to the outdoor 14, the knob 8 at the lower part of the indoor 13 side is rotated in a predetermined direction. By rotating the operating shaft 9, the lock pin 12, which has been engaged with the lock hole 17 of the surface grating 1, is rotated toward the storage groove 16 as shown by the two-dot chain line in FIG. As a result, the engagement between the lock pin 12 and the lock hole 17 is released, so when the glass door 2 is opened and the lower part of the screen grille 1 is pushed toward the outdoor 14 side, the lock hole 19 will be disengaged from the lock pin 1.
Since it is slightly larger than 8 and a gap S is formed between the upper side 1a and the support 20,
The grid 1 easily separates from the window opening 5 under its own weight, is positioned by the locking mechanism, and falls, forming an escape opening. Therefore, it is possible to escape from the indoor room 13 to the outdoor room 14 using this opening.

Note that when the surface grid 1 is installed in the opening 5, the guide pin 24 is located at the upper part of the guide groove 21 of the guide link 22, as shown in FIG. When detached from the window opening 5, the surface grid 1 falls through sliding between the guide pin 24 and the guide groove 21, and as shown in FIG. 4B, when the guide pin 24 reaches the end of the guide groove 21, Its falling position is regulated. Therefore, even if the surface grid 1 is installed on the second or third floor,
This prevents the danger of falling into the passageway, etc. below.

In the above, the operation for forming the escape opening is simply by rotating the knob 8 and moving the surface grating 1 to the outside 14.
Since it can be obtained by simply pressing the button, it can be done in a short time, making it extremely convenient and highly useful in emergencies.

FIG. 5 shows another embodiment of the present invention. In the case of the above-mentioned embodiment, the locking pin 12 at the tip is attached to the drain plate 6 in order to install the screen grid 1 in the upper position of the drain plate 6 in the window opening 5. To be located at the bottom of plate 6,
Although the locking device 7 is inserted and fixed into the building wall 4, this embodiment is an example of installation in a case where the size of the existing draining plate 6 is small and there is no draining plate. That is, the locking device 7 is installed so that the locking pin 12 at the tip protrudes to the outside 14, passing through the building wall 4 located at the lower part of the lower frame portion 3a of the window frame 3. The load of the surface lattice 1 is received by the tip portion protruding to the outside 14, and the upper part of the surface lattice 1 is secured by a support 20 attached to the building wall 4 located at the upper edge of the window opening 5. This is the configuration. Further, in this case, it is convenient to use a guide link 22 having a shape as shown by a two-dot chain line. Note that 25 is an auxiliary metal fitting for supporting the load.

In the case of this method, by simply providing a through hole in the building wall 4 and attaching the support 20 to the building wall 4 located at the upper edge of the window opening 5, the through hole 15 in the drain plate 6 and the building Since it is not necessary to provide the storage groove 16 in the wall portion 4, the installation work is easier than in the case of the previous embodiment.

It should be noted that the present invention is not limited to the above-mentioned embodiment; for example, a lever or a handle may be attached to the end of the operating shaft 9 on the indoor 13 side instead of the knob 8, and the drop position of the surface grating 1 may be changed. In order to regulate
Surface grid 1 with wire sent out from spring reel
Of course, it is possible to hang it, and various other changes can be made without departing from the gist of the present invention.
