Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the assembly structure of a shutter curtain, and in particular, the present invention is an assembly structure for a shutter curtain. The present invention relates to an assembly structure of a shutter curtain equipped with an auxiliary weight to which a weight can be attached.

[Prior Art] Conventionally, a shutter curtain constructed by connecting a plurality of slats in the vertical direction through an interlock part lowers due to the weight of each slat and seat plate during winding and unwinding operations, and closes the building opening. However, in the case of a shutter curtain installed in a building opening with a narrow opening width, the weight of the shutter curtain itself is insufficient. A structure in which an auxiliary weight is added to the slat has been proposed.

The method for attaching the auxiliary weight is as shown in FIGS. 5 and 6.
Directly weld the flat bar-shaped auxiliary weight 2 to the
Alternatively, a method is used in which the mounting member 3 to which the auxiliary weight 2 is welded is further welded to the slat 1.

However, each of the above mounting methods requires a welding process to add the auxiliary weights in addition to the shutter curtain assembly process, which not only reduces production efficiency but also leaves welding marks on the slats. This, combined with the fact that the attachment part of the auxiliary weight is exposed on the back side of the slat, has the disadvantage that the appearance of the assembled shutter curtain is significantly impaired.

[Problem to be solved by the invention] In view of the above-mentioned actual situation, the present invention was devised to eliminate the drawbacks of the conventional technology, and its purpose is to avoid spoiling the beauty of the shutter curtain. without the need for welding,
It is an object of the present invention to provide an assembly structure for a shutter curtain equipped with an auxiliary weight that allows the auxiliary weight to be easily attached to slats forming the shutter curtain.

[Means for Solving the Problems] In order to solve the problems, the technical means adopted by the present invention is to connect a plurality of slats in the vertical direction, each having an interlock portion curved at the upper and lower edges of the shaft. The engaging portions are curved at the upper and lower edges of a sub-panel that forms a tar curtain and has auxiliary weights provided inside, and the engaging portion of the sub-panel is engaged between the interlock portions of the slats. This is a characteristic feature.

[Operation of the invention] Therefore, according to the invention, the auxiliary weights can be easily attached by simply inserting the sub-panel to which the auxiliary weights are welded into each slat of the assembled shutter curtain.

[Example] The configuration of the present invention will be described in detail with reference to an example shown in the drawings.

In FIGS. 1 and 2, 1, 1, . . . are slats having interlock portions 1a, 1a curved on the upper and lower edges; The shutter curtains are connected in the vertical direction via the shutter curtains.

Further, 3, 3... are sub-panels in which flat bar-shaped auxiliary weights 2 are welded to the inner plane parts, and the upper and lower edges of the sub-panels 3, 3... are provided with engaging parts 3a,
3a are each bent.

Since the present invention is constructed as described above, in order to assemble a shutter curtain using the slats 1, 1, etc., flat bar-shaped auxiliary weights 2 are welded to the sub-panels 3, 3, respectively. , 3... are inserted horizontally between the interlock portions 1a, 1a of the vertically connected slats 1, 1..., the engagement parts 3a of the sub-panels 3, 3... ,3
a... are reliably engaged with the interlock portions 1a, 1a, and the auxiliary weights 2 can be attached to the slats 1, 1... extremely easily without using any welding means.

Therefore, the shutter curtain to which the above sub-panels 3, 3... are attached has an appropriate weight added by the auxiliary weights 2 installed in the sub-panels 3, 3..., and the shutter curtain can be stably driven up and down. At the same time, each slat 1, 1...
Since the interlock portions 1a, 1a... of the sub-panels 3, 3... are in a double engagement state with the engaging portions 3a, 3a... of the sub-panels 3, 3..., the interlock portions 1a, 1a... of the interlock portions 1a, 1a... will not affect the bending operation of the interlock portions 1a, 1a... There isn't.

Furthermore, as shown in FIGS. 3 and 4, the slats 1 are used to form a sub-panel 3' of the same shape, and the auxiliary weights 2 are welded to the inside of the sub-panel 3' to form slats 1, which are connected vertically. The interlock portions 1a, 1a, . . . may be configured to engage between the interlock portions 1a, 1a, .

[Effects of the invention] In short, the present invention forms a shutter curtain by vertically connecting a plurality of slats each having interlock portions curved at the upper and lower edges.
Furthermore, since the engaging portions are curved at the upper and lower edges of the sub-panel with auxiliary weights provided on the inside, and the engaging portions of the sub-panel are engaged between the interlock portions of the slats, the shutter curtain has an appropriate weight. It is possible to stabilize the raising and lowering operation of the shutter curtain by giving the shutter curtain, and it is also possible to omit the welding process of welding the auxiliary weight to the slats from the assembly process of the shutter curtain. Not only does this make it easier to improve production efficiency, but since no processing is required on the slats themselves during assembly, there are no welding marks caused by conventional welding, and even the mating sub-panels The slats have a double-wall structure, which improves the texture of the shutter curtain without making people aware of the existence of auxiliary weights, and produces extremely useful practical effects such as making it possible to create a shutter curtain with excellent aesthetics. It is something.

[Brief explanation of the drawing]
