Description

[Detailed description of the invention] Industrial application field The present invention is intended to prevent damage caused by the front and back surfaces of a shutter curtain coming into contact with each other when the shutter curtain is rolled up, in a shutter installed in an opening in a building, etc. This relates to a shutter curtain protection device for preventing accidents.

2. Description of the Related Art Shutters having a construction in which a shutter curtain formed by connecting a large number of slats in a flexible manner and wound around a winding drum were well known prior to the filing of this application, and are widely used in many buildings.

Problems to be Solved by the Invention In the conventional shutter with the above configuration, when the shutter curtain is wound onto the winding drum in order to open and close the shutter, the front and back surfaces of the shutter curtain come into contact with each other. The paint film is easily damaged by friction and scratching, and there are problems such as unpleasant contact sounds.

In view of these problems, the present invention prevents the front and back surfaces of the shutter curtain wound on the winding drum from coming into direct contact, thereby eliminating damage to the paint film and preventing the generation of unpleasant contact sounds. It is an object of the present invention to provide a protection device for a shutter curtain that can prevent such damage.

Means for Solving the Problems The present invention has the following technical means for achieving the above object. That is, in a shutter configured to wind up a shutter curtain formed by connecting a number of slats in a flexible manner onto a winding drum, a fitting recess is formed on the back side of each slat constituting the shutter curtain, and the connected slats are A protection device for a shutter curtain characterized in that a large number of elastic protection plates are fitted in the vertical direction of the slats between the fitting recesses of adjacent slats or an arbitrary number of slats, spanning the interlock part.

That is.

Function: The shutter curtain can be raised and lowered, and when it goes up, it is wound around the winding drum, and when it goes down, it is sequentially pulled out from the winding drum.

As mentioned above, the shutter curtain that is wound up on the winding drum is in a polymerized state. On the slats of the shutter curtain, a large number of elastic protection plates are arranged in the length direction of the shutter. Since each slat is fitted across the interlock part, an elastic protection plate is interposed between the front and back surfaces of the shutter curtain when it is wound up on the winding drum, preventing direct contact between each slat. There is no. This prevents the paint film on the shutter curtain from being damaged by friction or scratches.
Moreover, no unpleasant contact noise is generated when the shutter curtain is rolled up.

Example An embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a shutter curtain, and this shutter curtain 1 is constructed by connecting a number of slats 2 so as to be bendable by interlock portions 3 above and below the slats. Each slat 2 constituting the shutter curtain 1 has an integral fitting recess 4 formed in the longitudinal direction on its back side, and this fitting recess 4 has locking edges formed at the top and bottom. There is. Reference numeral 5 denotes an elastic protection plate, and the elastic protection plate 5 is formed with bent legs 6 on the upper and lower sides, and the bent legs 6 are formed with locking portions 7 that are fitted and locked into the fitting recesses 4. has been done. The elastic protection plate 5 is formed in such a length that it can be fitted into the fitting recesses 4 of the slats 2 for each appropriate number of shutter curtains 1, spanning the interlock. It is fitted by fitting the locking part 7 of the bent leg 6. Here, a large number of elastic protection plates 5 are fitted near both ends of the shutter curtain 1 in the vertical direction and width direction at appropriate intervals. The elastic protection plate 5 is a molded body of rubber, synthetic resin, or the like.

2 and 3 respectively illustrate the winding structure of the shutter curtain 1.
The figure shows a forward winding mode, and FIG. 3 shows a reverse winding mode. In these figures, 8 is a winding drum, and the shutter curtain 1 is wound up in a polymerized state one after another. In the case of forward winding, the front surface of the shutter curtain 1 is on the outside, and in the case of reverse winding, the back surface is on the outside. It is rolled up so that it is on the outside. However, in either case, the elastic protection plate 5 is interposed between the overlapping parts of the shutter curtains 1 that are sequentially wound up, so that the overlapping parts do not come into direct contact with each other. Therefore, when the shutter curtain is rolled up and pulled out, there is no damage to the coating film due to friction, scratches, etc., and no unpleasant contact noise is generated.

The elastic protection plates 5 are fitted on the back side of the shutter curtain 1 at appropriate intervals as described above, but this is done, for example, between the upper and lower slats 2 that are connected as shown in FIG. It may be fitted continuously in the direction, or it may be fitted sequentially to every other connected slat 2, as shown in FIG.
Since the elastic protection plate 5 is flexible and can be attached to and detached from the fitting recess 4 of the slat 2, it may be fitted after the shutter is installed.

Effects of the invention Since the present invention is constructed and operates as described above, it prevents the front and back surfaces of the shutter curtain wound on the winding drum from coming into direct contact with each other, and prevents the painting from being caused by friction, scratching, etc. This has extremely useful practical effects, such as eliminating damage to the membrane and preventing the generation of unpleasant contact sounds.
