[0002]

2. Description of the Related Art A shutter curtain, which is provided at an opening of a building and is opened and closed by moving up and down with respect to the opening, has a substantially U-shaped cross section which is disposed opposite to both right and left edges of the opening. Left and right side edges are inserted into the guide rails, and the vertical movement is guided.

[0003] This shutter curtain is composed of a plurality of slats formed in, for example, a strip shape elongated in the left-right direction, and is connected to each other by curls formed on upper and lower edges of the slats. In this way, a shutter curtain is constituted by being connected in the vertical direction, and a locking slat provided with a locking device is connected at a substantially intermediate position in the height direction of the shutter curtain.

This locking device is provided with a locking bar projecting from both ends of the locking slat, and an operating section arranged on the indoor side surface of the locking slat is operated to move the locking bar forward and backward. I have.

[0005] Locking of the shutter curtain in a closed state is performed by engaging a locking bar of a locking device with a hook-shaped engaging piece projecting into a groove of each guide rail. I have.

However, according to the structure of the conventional guide rail described above, the substantially U-shaped cross section into which the side edge of the shutter curtain is inserted is designed to be small in size to save space. Due to the manufacture, the amount of protrusion of the engagement piece with which the locking bar of the locking device engages is limited. That is, since the insertion length of the side edge of the shutter curtain is made sufficient, the inside of the groove portion of the guide rail is reduced. There is a disadvantage that the engaging piece projecting to the locking bar cannot be made large, and the engagement amount with the locking bar may not be sufficient due to the small amount of projection of the engaging piece. There is a disadvantage that the reliability of the state cannot be obtained.

Further, the size of the guide rail itself is reduced in the guide rail as described above, and it is impossible to provide the engagement piece outside the guide rail for security. It becomes impossible to protrude the locking bar in a long length, and from this, the engagement state between the engagement piece and the locking bar is not sufficient, and the locking state may not be sufficient. .

Further, the insertion length of the side edge of the shutter curtain in the groove portion of the guide rail is set to a sufficient length,
Even when the shutter curtain is designed in consideration of the amount of protrusion of the engagement piece, the side edge of the shutter curtain does not always move in the vertical direction in the vertical movement, and may slightly swing in the left-right width direction. Also, since the connection state between the slats is configured to have a certain degree of freedom, the connection state between the slats may be deviated to the left or right. However, there is a problem that contact or collision occurs with the engaging pieces, the shutter curtain cannot be moved smoothly, abnormal noise is generated, and the shutter curtains are damaged.

In order to solve the above-mentioned problems, the present invention saves space without deteriorating the function as a guide rail for smoothly guiding the movement of the shutter curtain, and relates to a lock bar for a locking device. It is an object of the present invention to provide a guide rail structure capable of securing the locking state and obtaining the reliability of locking.
