Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a locking device for an architectural shutter with a daylight window, in which each slat is detachably connected to allow daylight to enter.

[Problems to be solved by the prior art and the invention] In general, this type of architectural shutter with daylighting window has slats arranged side by side at a predetermined interval.
They are connected via a connecting body such as a string or belt, and when the connecting body is tense, the adjacent slats separate and the lighting window opens, and when the connecting body is relaxed, the adjacent slats come into contact with each other. It is configured to block the lighting window. Even in such architectural shutters with daylight windows, it is necessary to install a locking device for security reasons, but in the past, even architectural shutters with daylight windows were not equipped with normal architectural shutters without daylight windows. Since the locking device is simply installed, the locking device must be operated separately from the opening/closing operation of the slats, which is troublesome, especially when installing architectural shutters with daylight windows to window frames, etc. When a window shutter is used as a window shutter, locking and unlocking operations are extremely troublesome as the window must be opened and closed each time. However, this has caused problems such as forgetting to open the lock and accidentally raising the shutter slat while the lock is in the locked state, resulting in damage to the architectural shutter and the locking device.

[Means for Solving the Problems] The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation. Through a connecting body whose upper end is connected to the winding wheel side, when the connecting body is in tension, adjacent slats separate to open the lighting window, and when the connecting body is relaxed, they come into contact and close the lighting window. At the same time, the lower end of the connecting body is connected to a latch body which is biased and attached to the seat plate so as to be always operated in the locked position side, and the latch body is connected between the slat and the seat plate. When they are separated and the connecting body is under tension, it is moved to the unlocked position against the biasing force, and when the slat and seat plate come into contact with each other and the connecting body is relaxed, it is moved to the locked position. It is characterized in that it is configured to be engaged with a latch.

With this structure, the present invention enables a locking device provided in a building shutter to be automatically locked and unlocked by being connected to the raising and lowering operation of the shutter curtain.

[Example] Next, the present invention will be described in more detail based on an example shown in the drawings. In the drawing, 1 is a window shutter installed outside the window frame of a house, building, etc., and the shutter curtain that constitutes the window shutter 1 is made by connecting a plurality of slats 3 that are long in the left and right direction. They are connected vertically at a predetermined interval by means of bodies (corresponding to the connecting body of the present invention) 5 to form a continuous configuration. That is,
In this embodiment, the slat 3 is made of a hollow extruded aluminum section, and the slat 3 is provided with a through hole 4 in the vertical direction. 5 is slidably penetrated therethrough.
Locking claws 6 that lock onto the edges of the through holes 4 in the slats 3 from the inside are protruded from the connecting band 5 at a predetermined interval larger than the vertical width of the slats 3. They are locked and held at a predetermined interval, respectively. Therefore, when the slat 3 is suspended by the connecting band 5, that is, when the connecting body is in tension, the upper end edge of the slat 3 and the lower end edge of the upper slat 3 adjacent thereto exist for a predetermined distance. They are separated from each other, and the space between them serves as a daylighting window 7. Furthermore, the upper end of the connecting band 5 is fixed to the winding wheel 8 side, and the lower end is connected to a latch body 10 provided on a seat plate 9, which will be described later. A tar curtain 11 is configured. and,
By rotating the winding wheel 8 by operating the operating handle 12 provided on the indoor side, the connecting band 5 is wound up on the winding wheel 8 together with the slat 3.
Alternatively, if the shutter curtain 11 is sequentially lowered from the open state along the guide rail 13 by operating the operating handle 12 to rotate the winding wheel 8 back, the shutter curtain In the curtain 11, when the seat plate 9 is just in contact with the lower frame 14 of the window frame, each slat 3 is suspended by the connecting band 5 and separated, and the curtain 11 is in a lighting state with the lighting window 7 opened. There is. Then, from this lighting condition, the shutter curtain 1
When 1 is lowered, slat 3 (or seat plate 9)
The lighting windows 7 formed between the upper slat 3 and the adjacent upper slat 3 are sequentially closed from the lower one,
The window is configured to be in a fully closed state when the uppermost daylighting window 7 is closed.

As described above, the latch body 10 to which the lower end of the connecting band 5 is connected is rotatably biased to the seat plate 9 via the pivot 10a so as to be displaced by its own weight into the locked position protruding toward the guide rail 13. However, when the upper slat 3 contacts the seat plate 9 with the seat plate 9 in contact with the lower frame 14 and the connecting band 5 loosens, the latch body 10 will move under its own weight to the guide rail. 1
The locking device 16 of the present invention is configured such that the locking device 16 of the present invention is configured such that the locking device 16 rotates downward to the 3 side and protrudes, and is displaced to the locking position side where it automatically latches onto the latch 15 provided on the guide rail 13. has been done. still,
In the figure, 17 is a window body installed in the window frame.

In the embodiment of the present invention constructed as described above, when the shutter curtain 11, which is currently wound up by the winding wheel 8 and is in the open state, is lowered by operating the operating handle 12, the shutter curtain In the curtain 11, each slat 3 is held suspended by the connecting band 5 while the connecting band 5 is under tension until the seat plate 9 comes into contact with the lower frame 14.
A lighting window 7 with a predetermined distance is formed between adjacent slats 3 (or between the slats 3 and the seat plate 9), and therefore, lighting and ventilation are provided from this lighting window 7. I can do it. Then, when the shutter curtain 11 is further lowered, the upper slats 3 adjacent to the lower slats 3 (or the seat plate 9) are brought into contact with and placed on the lower slats 3 (or the seat plate 9). The windows are closed one after another from the side, and by closing all the lighting windows 7, the windows are completely closed.

As described above, in the present invention, the window can be placed in an appropriate state such as fully closed, daylighting, or fully open, depending on the resident's selective engagement, and in the daylighting state, Light and ventilation can be brought in through the lighting window 7, but at this time, the locking device 16 remains closed without opening and closing the window body 17 each time, and the operating handle for opening and closing the shutter curtain 11 is used. The locking/unlocking operation can be automatically performed by only a series of 12 operations.

That is, in the lowering operation of the shutter curtain 11, until the seat plate 9 comes into contact with the lower frame 14,
Since the connecting band 5 suspends the slat 3 and is in a tensioned state, the latch body 10 is oriented upward as shown in FIG. 3 and is in the unlocked state. However, when the connecting band 5, which had been tensed due to the contact of the seat plate 9 with the lower frame 14, is relaxed, the latch body 10 rotates downward under its own weight and protrudes to the outside locking position and guides the latch body 10. Latch hook 15 provided on the rail 13 side
When the locking device 16 is locked, the locking device 16 is automatically locked. On the other hand, during opening operation,
The latch body 10, which has been in the locked position due to the loosening of the connecting band 5, has the slat 3 immediately above it separated from the seat plate 9 and is suspended by the connecting band 5, contrary to the above-mentioned closing operation. When the latch 5 is tensed, it automatically rotates upward against the biasing force of its own weight and enters the unlocked position, and the lock with the latch 15 is released and the lock is automatically opened. becomes. Therefore,
In the present invention, the locking/unlocking operation of the locking device is performed completely automatically in conjunction with the opening/closing operation of the shutter curtain 11, as in the conventional method. Not only does it not require a separate and troublesome operation such as opening the window body 17 each time, it also eliminates the need to forget to operate the locking and unlocking operations, which is excellent in terms of security, and also improves security. There is no possibility that the locking device or the like will be damaged due to forgetting to unlock the door when the door curtain 11 is raised.

Further, in the present invention, the latch body 10 is directly connected to the connecting band 5, and the unlocking and locking operations are performed by tensioning and relaxing the connecting band 5. By connecting and fixing the seat plate 9
The latch body 10 can also be used as a member forming the shutter curtain 11.
Since the latch body 10 automatically moves in and out using the tightening action of the connecting band 5, there is no need for any special member to move the latch body 10 in and out, and the overall structure can be improved. It has the advantage of being extremely simple.

Furthermore, in this case, in order to change the latch body 10 from the locked position to the unlocking position, the connecting band 5 must be raised and tensioned, instead of lifting the slat that is in contact with the upper side. In the half-open state where the door is opened, there is no problem in which an unscrupulous person could lift the slat directly above the seat plate and unlock it, making it excellent in crime prevention.

It goes without saying that the present invention is not limited to the above-mentioned embodiment, but the point is that the latch body is attached to the lower end of the connecting body of the connecting band 5 that connects the slats at a predetermined interval. The latch body may be such that when the connecting band is relaxed or tensed, the locking or unlocking operation is performed using the bias of the bullet rather than the latch body's own weight. Good too. Furthermore, the latch body 10 may be pivoted so as to be rotatable in the front and rear directions as in the second embodiment shown in FIGS. 4 and 5.

[Operations and Effects] In summary, the present invention is constructed as described above, and the shutter curtain can be used not only in the fully open state and the fully closed state, but also in the daylighting state where a daylighting window is opened between each slat. However, the latch body moves in and out of the latch side in conjunction with the up-and-down movement of the shutter curtain to automatically lock and unlock the door. Therefore, the troublesome locking and unlocking operations of the latch body as in the prior art are completely unnecessary, and the operability can be extremely improved. In addition, the latch body is connected to the lower end of the connecting body, and the latch is moved in and out of the latch using the tightening and loosening operations of the connection body. There is no need to provide a separate member, and the seat plate can be attached by connecting the latch body to the connecting body, making the structure simple.

Moreover, the latch body in the locking position does not have to be moved to the unlocking position simply by lifting the slat directly above the seat plate, and the connecting body must be pulled and tensed, so that the latch body is excellent in security.
