Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a correction device for a horizontal pull shutter.

[Conventional technology]

In a conventional horizontal pulling shutter, as shown in FIG. 4, winding portions 2 and 3 are formed on both side edges of a plurality of plate-like slats 1, and the winding portions are arranged in the longitudinal direction. A few
Are rotatably fitted to each other so that the slats 1 can be bent with respect to each other. Wheels are attached to the upper ends of all or part of these slats 1, and the wheels are fixed to the ceiling. At the lower end of all or part of the slat 1, there is a horizontal pull shutter in which a guide wheel is attached and each of the guide wheels is accommodated in a guide groove fixed to a sill.

[Problems to be solved by the device]

In the above conventional horizontal pull shutter, the shutter 4A is the fourth
In the case of pulling as shown in the drawing, the pulling force is transmitted to each slat 1 without loss, so that each slat 1 moves smoothly. On the contrary, when the shutter 4 is pushed as shown in FIG. Tries to escape in the directions 4 and 5 which are orthogonal to the direction in which they are pushed, and there is rattling between the engaged winding parts of each slat 1, so the pushing force is 100% in the direction in which they push each slat. There was a problem that each slat did not move smoothly without being transmitted.

An object of the present invention is to provide a correction device for a horizontal pull shutter that can solve the above problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention arranges a plurality of plate-like slats in a longitudinal direction and rotatably fits the winding portions formed on the adjacent side edges thereof so that the slats are mutually connected. The upper and lower ends of all or a part of the slats are connected to each other by bending, and the wheels are attached to the hanger rails fixed to the ceiling. In a horizontal pull shutter in which a guide wheel is attached and each of the guide wheels is housed in a guide groove fixed to a sill, a shaft rod is inserted into the rotatably fitted winding portion of each slat, and each slat is inserted. A groove is provided near one of the front and back sides of the groove, and the groove and the other side of the slat are wound at appropriate points such as the upper end, the lower end, and the middle of the surface where the groove is provided. The fixing plate that is fixed to the flat part between the Tsu bets is the other one formed by providing the engaging piece which projects to engage into the groove provided on the slats adjacent with rolling portion fitted to the winding unit.

[Action]

In the state where the straightening device having the above configuration is attached to each slat of the horizontal pulling shutter, when pulling the shutter, the pulling force is transmitted to each slat without loss similarly to when pulling the shutter without the straightening device attached, On the contrary, when pushing the shutter, the engaging pieces protruding from the adjacent slats are engaged with the groove of each slat, and the force for pushing the shutter is applied to each engaging piece. Act like a stake that holds the slat away in the directions 4 and 5 orthogonal to the direction in which they are pushed, and by means of the shaft rods inserted into the interlocking engaging parts of each slat. Since the rattling between the winding parts is prevented, the pushing force is transmitted to each slat in the pushing direction by almost 100%, and each slat moves smoothly.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 6 denotes a plate-like slat having winding portions 7 and 8 formed on both side edges thereof. A groove 9 which is recessed from the front surface to the back surface is provided at a position closer to 8. A plurality of the slats 6 are arranged in the longitudinal direction, the winding portions 7 and 8 formed on the adjacent side edges are rotatably fitted, and the shaft rod 10 is inserted into each fitting portion. The slats 6 are flexibly connected to each other. At the upper end and the lower end of the surface of each slat 6 connected in this way, the groove 9 and the other winding portion 7
The fixing plates 11 and 12 are fixed to the flat portion between them by the rivets 13 and 14, and the adjacent slats 6 each having the winding portion 8 that fits into the other winding portion 7 are fixed to the fixing plates 11 and 12. The engaging pieces 15 and 16 are provided so as to project so as to engage with the groove 9 provided in the. Reference numeral 17 denotes a wheel mounted on the upper end of each slat 6 by a support plate 18, which is suspended on a hanger rail fixed to the ceiling. Reference numeral 19 is a guide wheel attached to the lower end of each slat 6 by a support plate 20, and is accommodated in a guide groove fixed to the sill. Reference numeral 21 indicates a horizontal pull shutter assembled by the above parts.

The present invention is not limited to the above embodiment, but the groove 9
The slat may be recessed from the back surface to the front surface, and the fixing plate and the engaging piece may be attached to the back surface of each slat 6, and the fixing plate and the engaging piece may be attached to the middle portion of each slat 6 and other appropriate places. There is also.

[Effect of device]

Since the present invention is configured as described above, the force of pushing the horizontal pull shutter formed by connecting the plate-shaped slats in the vertical direction can be transmitted to each slat in the pushing direction in nearly 100%. (EN) It is possible to provide a straightening shutter straightening device capable of smoothly opening and closing by eliminating rattling between winding parts that are rotatably fitted together.
