Description

[Detailed Description of the Invention] This invention relates to a shutter locking device mainly used for residential shutter shutters.

Currently, the locking mechanism of this type of shutter rain door is usually attached to the drain at the bottom of the slat curtain. If the position is low, you will have to bend down to operate the lock, making it difficult to handle the lock.Furthermore, if the window is fitted at the bottom, the locking mechanism may be difficult to handle. There is a problem that even if it is installed, it cannot be operated.

For this reason, it is desirable for shutter rain shutters to have a locking mechanism on the middle slat of the slat curtain. It is rare to find shutter shutters that use the same method as they are and use an intermediate locking system.

However, according to the structure of conventional shutter storm shutters with an intermediate locking method, the span of the shutter is short and the locking mechanism protrudes from the back side of the intermediate slats, so when the curtains are rolled up, the intermediate slats are closed. The locking mechanism collides with the slat that is wound up earlier, causing damage to other slats or deforming the same slat.

The present invention has been made in order to solve the above-mentioned problems. In other words, the purpose of the present invention is to prevent the locking slat connected to the middle of the slat curtain from damaging other slats. An object of the present invention is to provide a shutter locking device that prevents the shutter from being damaged.

As a means for achieving the object, the locking device of the present invention includes a locking slat whose vertically intermediate portion is a flat plate, which is connected to the middle of the slat curtain, and the locking slat has the flat plate. A downward flange plate and an upward flange plate are branched and overhang molded on each of the upper and lower back sides of the part, and furthermore, a guide cover for guiding and holding a bar-shaped lock bar that slides in a horizontal stroke is provided. It is characterized in that it is fixed to the locking slat while being sandwiched between the flat plate portion and the two flange plates.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

In the locking device of the embodiment, as shown in FIGS. 1 to 11, a locking slat 2 is connected to the middle of a slat curtain 1, and the slat 2 has a vertical middle portion. A flat plate part 2a is formed, and a downwardly facing upper brim plate 2b and an upwardly facing lower brim plate 2c are branched and overhang molded on the upper and lower back sides of the flat plate part 2a, respectively. The thickness between the portion 2a and the upper flange plate 2b is approximately equal to the thickness of the other slats 3.

Thus, a flange 4a having a U-shaped cross section is suspended from the lower end of almost each half of the left and right sides of the back side of the locking slat 2 (in the drawing, the left half from the center C is shown). A guide cover 4 is attached, and the upper end of the cover 4 is sandwiched between the flat plate part 2a and the upper flange plate 2b, and the flange 4a is sandwiched between the flat plate part 2a and the lower flange plate 2c. Then, the lower flange plate 2c is caulked to prevent it from coming off.

The opening at the end of the guide cover 4 near the center C of the slat 2 is partially closed by an edge plate 4b formed by folding the back plate. It has the effect of regulating the stroke of 6.

Further, on the side of the inner surface of the U-shaped section of the guide cover 4, a click spring 7 consisting of a spring plate fixed to the cover 4 by rivets 8 at two intermediate bases is attached. Both sides of 7 float from the inner surface of the cover 5, and
A crest 7a is formed by bending, and the distance between the two ridges 7a is twice as long as the distance between the lock holes 5a of the lock bar 5, which will be described below.

Next, in the inner space of the U-shaped cross section of the guide cover 4,
A long body formed by welding and connecting a lock bar 5 and a knob plate 6, each of which is a long plate, is inserted through the lock bar 5.
The knob plate 6 is formed by a finger hook part 6c near the center C of the slat 2, an intermediate retracting step part 6a, and a side overlap part 6b.

Therefore, this knob plate 6 has an overlapping portion 6b.
is welded to the back surface of the lock bar 5, and the edge plate 4b of the guide cover 4 is fitted into the retractable stepped portion 6a.

In addition, at four locations in the longitudinal direction of the lock bar 5,
Click holes 5a are bored into which the respective peaks 7a of the above-mentioned click spring 7 fit.

By the way, the side end of the slat curtain 1 is inserted into the opening groove of the shutter rail 9, and the shutter rail 9 is composed of a vertical frame having a substantially U-shaped cross section, and there is a vertical frame in the middle of the depth of the rail interior. When a partition plate 9a is formed and the partition plate 9a is at a required height, that is, in the illustrated case, at the height when the curtain 1 is closed (FIG. 1), the lock bar 5
A rectangular lock hole 9b is bored at a height opposite to .

The right half of the locking slat 2 and the shutter rail on the right side of the shutter are formed symmetrically and in the same manner as described above.

Next, the operation and operation of the locking device according to the embodiment configured as described above will be described.

The locking and unlocking operations are performed by manually pushing and pulling the finger hook 6c of the knob plate 6 near the center C of the slat in the longitudinal direction. 3), the lock bar 5 is located at the end of the stroke on the slat center C side, and each peak 7a of the click spring 7 is located in the first and third clicks from the side among the four click holes 5a. It is fitted into the hole 5a to lock the lock bar 5 in the retracted position within the slat 2.

Furthermore, push the knob plate 6 to the side to remove the retracting step portion 6a.
At the stroke end position in FIG. 4, where the inner end of the lock bar 5 touches the edge plate 4b, the protrusion of the lock bar 5 is in the lock hole 9.
b to lock its vertical movement,
The ridges 7a of the click spring 7 fit into the second and fourth click holes 5a from the side, and the lock bar 5 is reliably clicked into the locked position.

In the locking device of this embodiment, since the thickness of the locking slat 1 is almost equal to the thickness of the other slat 3, the guide cover 4 does not touch the other slat 3 when the slat curtain 1 is rolled up. There is no risk of collision.

As described above, according to the shutter locking device of the present invention, a guide cover is attached to the back side of the locking slat in the middle of the slat curtain, and a locking bar is guided and held between the locking slat and the locking slat. Therefore, the guide cover does not collide with other slats when the curtain is rolled up, thereby preventing damage to other slats and providing a safety effect.
