Description

[Detailed Description of the Invention] This invention relates to a guide rail equipped with a shutter locking device.

In the general configuration of a shutter locking device, a lock bar is guided and held horizontally on the back side of a slat curtain, and extends to the side of the curtain by sliding strokes, and the lock bar is guided and held vertically along the side edges of the curtain. A method is adopted in which the slat curtain is locked by fitting it into an engaging part of a locking hole or a locking recess provided at a required height in the guide rail of the shutter.

However, in the specific structure of the conventional locking device, a separate frame plate is installed in the depth part of the guide rail, and the engaging part of the lock hole or lock recess is formed. However, such a conventional structure requires construction work on site, and as a result, there is a problem in that it is troublesome to install the locking device.

The present invention has been made to solve the above-mentioned problems, and the purpose of the present invention is to provide a shutter guide rail with a locking function that is easy to manufacture and easy to install on-site. It's about doing.

As a means to achieve this purpose, the guide rail of the present invention consists of a vertical frame whose cross section is approximately U-shaped, and furthermore, a partition plate is integrally formed in the middle of the depth of the frame, and the required length of the partition plate is The shutter guide rail is characterized by an engaging portion formed at the height.

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

The guide rail of the embodiment has the function of a locking device, and as shown in FIGS. 1 to 11,
A locking slat 2 is installed in the middle of the slat curtain 1.
The slat 2 has a flat plate part 2a with a flat intermediate part in the vertical direction, and a downwardly facing upper flange plate 2b on the upper and lower back sides of the flat plate part 2a, respectively. , upward facing lower brim plate 2c
is formed with a branched overhang, and the flat plate part 2
The thickness between a and the upper flange plate 2b is approximately equal to the thickness of the other slats 3.

Therefore, a flange 4a having a U-shaped cross section is suspended from the lower end of approximately 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 rail 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, and this edge plate 4b is a knob plate to be described later. 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 includes a finger hook part 6c near the center C of the slat 2, an intermediate retraction step part 6a, and a side overlap part 6.
b.

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 ends of the slat curtain 1 are inserted into the opening grooves of the guide rail 9 of the shutter which constitutes one embodiment of the present invention.
consists of a vertical frame whose cross section is approximately U-shaped,
A partition plate 9a is integrally formed in the middle of the depth of the inner space of the rail. Further, at a required height of this partition plate 9a, that is, in the illustrated case, the height at which the curtain 1 is closed (FIG. 1), a lock hole formed in a square shape is provided at a height opposite to the lock bar 5. The joining part 9b is perforated.

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 device thus configured 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 protruding part of the lock bar 5 touches the engaging part 9b.
At the same time, the peaks 7a of the click spring 7 are fitted into the second and fourth click holes 5a from the side, and the lock bar 5 is securely in the locked position. Click held.

In such a guide rail, the engaging portion 9b with which the lock bar 5 engages is connected to the shutter rail 9.
Since the engaging part 9b is integrally formed in the middle of the inner part of the building, there is no risk of the mounting width of the shutter being expanded unnecessarily. Since there is no need to apply pressure, the work is as simple as installing a guide rail.

The engaging portion 9b may be provided in a plurality of stages above and below, or may be formed into an uneven shape by pressing or the like.

As described above, according to the guide rail of the shutter according to the present invention, the partition plate is integrally formed on the deep side of the inner space of the guide rail, and the engaging portion is formed on the partition plate. Therefore, the above-mentioned engaging part does not have any influence on the attachment part of the structure.
The installation work is easy, and the engagement length of the lock bar can be made sufficiently long, which has the effect of improving the practicality of the guide rail with a locking function.
