Description

[Detailed description of the invention] [Industrial application field] This invention is a shutter curtain that prevents a shutter curtain, which moves up and down guided by guide rails on both the left and right sides, from falling off the guide rails due to wind pressure, external force, etc. This invention relates to a mechanism for preventing the tar curtain from coming off.

[Conventional technology]

Generally, due to wind pressure or external force caused by typhoons, etc.
Conventionally, there are the following so-called slip-off prevention mechanisms that prevent the shutter curtain from bending and slipping off from the guide rail.

B. There are some that use roughly L-shaped wind-resistant hooks. In this system, a plurality of windproof hooks are attached to both ends of the shutter curtain, and a guide rail is formed into an L-shaped cross section to be engaged with the windproof hooks, and the shutter curtain is fitted into the guide rail. . When wind pressure or the like acts on the shutter curtain, even if the shutter curtain bends in the front-rear direction in plan view, the wind-resistant hooks are locked within the guide rail to prevent the shutter curtain from coming off.

(b) There is also a type of shutter curtain in which a reinforcing column is attached to the center. This involves forming set holes in the floor and fixing holes in the ceiling side lintel, attaching reinforcing columns, and then fixing the reinforcing columns and the shutter curtain with fixtures. Therefore, even if the shutter curtain tries to bend due to wind pressure or the like, since it is fixed integrally with the reinforcing column, the shutter curtain does not bend and is prevented from falling off.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional technology has the following problems.

B. When winding up the shutter curtain using wind-resistant hooks, the hooks overlapped each other on the winding drum, causing the winding to collapse.

(b) Even when the shutter curtain was bent due to wind pressure, etc., the wind-resistant hooks were sometimes not locked to the guide rails, causing the shutter curtain to come off. In addition, when the shutter curtain was bent and the windproof hook was locked to the guide rail, it made an abnormal noise, causing noise.

(c) For models that use reinforcing columns, dedicated holes are formed in the floor and lintel, and mounting holes are formed on the shutter curtain side for fixing devices to fix the reinforcing columns to the shutter curtain. In order to attach the reinforcing pillars, various processing was required.

D. Also, when installing reinforcing columns, it is difficult to lift and operate the heavy reinforcing columns every time you need them.
In addition to being time-consuming and complicated, storage space is also required after the reinforcing pillars are removed when the frontage is opened when the shutter curtain is raised.
It was inconvenient to handle the reinforcing columns.

This idea was made in view of the above problems, and it does not cause the shutter curtain to collapse or make noise, is easy to handle and operate, and is reliable by suppressing the deflection of the shutter curtain. It is an object of the present invention to provide a shutter curtain retaining mechanism that prevents the shutter curtain from coming off.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention involves drilling locking holes at both ends of the shutter curtain, which moves up and down while being fitted into guide rails installed on both sides of a frontage opening, etc. A stopper is configured to be freely inserted into and removed from a locking hole through an insertion hole formed in a guide rail, and constitutes a shutter curtain slip-off prevention mechanism that prevents the shutter curtain from slipping off from the guide rail. It is.

[Effect]

According to the locking mechanism of this invention, when the shutter curtain is moved down to close the frontage opening, etc., the locking hole drilled in the shutter curtain is located facing the side surface of the guide rail, so that If you operate the locking body attached to the side of the guide rail and insert the locking body through the locking hole, the shutter curtain will be fixed on both sides with the locking body, so wind pressure etc. will not be applied to the shutter curtain. Even if the shutter curtain tries to bend under the influence of the guide rail, the shutter curtain is restrained by the locking body, and the shutter curtain is prevented from coming off the guide rail.

In addition, when moving the shutter curtain upward to open a frontage opening, etc., the locking body is removed from the locking hole of the shutter curtain, thereby locking the shutter curtain and the locking body. Since the relationship is released, the shutter curtain can be moved up.

[Effect of idea]

Since this invention is constructed as described above, it has the following effects.

Since members such as windproof hooks are not attached to the shutter curtain, the windproof hooks do not overlap each other even when the shutter curtain is rolled up, and the winding does not collapse.

Since the locking body is inserted into the locking hole of the shutter curtain and locks the shutter curtain, the deflection of the shutter curtain is suppressed and it is reliably prevented from falling off the guide rail. Unlike the use of wind-resistant hooks, there is no noise or slip-off.

C. Unlike the use of conventional reinforcing columns, there is no need to attach and remove a separate heavy object each time the shutter curtain is opened or closed, and the locking body is inserted into the locking hole by operating the locking body when the shutter curtain is closed. By doing so, you can prevent the shutter curtain from coming off the guide rail, and by operating the locking body and pulling it out from the locking hole, the shutter curtain can be moved upward, making it easier to handle the locking mechanism. It is simple and convenient and has good operability.
