Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a winding body structure for a building shutter provided in an opening of a building.

[Problems to be Solved by Prior Art and Invention] Generally, in this type of architectural shutter, panel-shaped slats are connected in series to form a shutter curtain, and the shutter curtain is provided with the shutter curtain. Some of them are configured to be wound up and stored in an inner winding cylinder. However, in such a building shutter,
Due to the irregular winding, there were problems such as the slats being damaged by each other, and the winding center being eccentric to prevent smooth opening and closing. Therefore, as in the Japanese Utility Model Publication No. 57-29040, which was previously proposed by the applicant, panel-shaped slats each having a width of n sheets are successively connected to form a shutter curtain, and the shutter curtain is formed. Although there is a system in which the tar curtain is wound and stored in an n-sided winding cylinder, orderly winding is realized. However, since this uses a polygonal winding cylinder that is not easy to manufacture, the manufacturing cost is a problem. Was there.

[Means for Solving the Problems] The present invention was conceived with the object of providing a winding body structure for a building shutter which can eliminate these drawbacks in view of the above-mentioned circumstances. A shutter curtain formed by connecting a series of panel-shaped slats in a series, in a building shutter for winding and storing in a polygonal shape on a winding drum in a shutter case, while forming the winding drum in a cylindrical shape, On the outer peripheral surface of the winding drum, a winding piece for contacting with the first-roll slat or its connecting portion to position the first-roll slat is fixed for each connecting portion or each slat. Is.

According to the present invention, the winding cylinder for winding and storing the shutter curtain in a polygonal shape can be constructed very simply.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 is a shutter curtain of a building shutter, and the shutter curtain 1 is erected on both left and right sides of an opening by a winding operation and a rewinding operation of a winding drum 3 accompanied by driving of an electric motor 2. The basic structure such as moving up and down along the guide rail 4 is the same as the conventional one.

S is a slat that constitutes the shutter curtain 1. The slat S is a frame part 6 having an interlock part 6a integrally fixed to both upper and lower edges of the panel part 5 by concave and convex fitting. Is configured. And S
Are connected in series by interlocking connection with the adjacent slats S to form the shutter curtain 1, but in the embodiment, the slats S which are sequentially widened (up and down width) every six sheets from the suspension base side. The shutter curtain 1 is formed by connecting the two. That is, the shutter curtain 1 forms a hexagonal winding layer, and is wound up and housed in a layered manner on the winding drum 3 so that each interlock coupling portion is positioned on the radiation.

E is a final slat of each winding layer connecting the winding layers, but the final slat E is formed to have a width dimension different from that of the slat S constituting the same winding layer. That is, in the shutter curtain 1 constituted by the slats S which are simply formed to be wider every six sheets, some winding deviation occurs. Therefore, in this embodiment, the final slats E of the winding layers are formed.
Is configured as a width adjusting slat whose width dimension is set so as to absorb the winding deviation of each winding layer. As a result, each slat S, E causes the slats S, E to be superposed in the stored state,
It is formed so as to form a layer completely parallel to E.

On the other hand, the winding drum 3 provided in the shutter case 7
Is a cylindrical shape, and the shutter curtain 1 to which the suspension element is connected is wound into a hexagonal shape as described above. A winding piece 8 for contacting the central portions of the slats S1 and E1 to position the winding position thereof is fixed at a predetermined interval in the circumferential direction, and is set to abut each slats S1 and E1. It has become. In addition, the winding piece 8 is slats S1,
It is made of rubber elastic material so as not to damage E1.

In the embodiment of the present invention constructed as described above, the winding drum 3 is formed by fixing the winding piece 8 on the outer peripheral surface of the cylindrical winding portion, and at the time of winding, each slat S1 of the first winding is wound. ,
The shutter curtain 1 is placed in contact with the center of each E1 to position the winding position, and the shutter curtain 1 is wound and stored in an orderly hexagonal shape.

As described above, in the embodiment of the present invention, the shutter curtain 1 formed of the panel-shaped slat S is used.
Is to be wound and stored in a polygonal shape, the winding cylinder 3 for winding the same does not have a polygonal shape as in the conventional case, but the winding piece 8 is fixed to a general-purpose cylindrical shape. You can shape with. Therefore, the manufacturing of the winding drum 3 is significantly simplified, and as a result, the manufacturing cost of the winding drum 3 can be significantly reduced.

Moreover, since the winding piece 8 is formed of an elastic member so as not to damage the slat S by the contact during winding, the coating of the slat S and the like can be sufficiently protected.

The present invention is not limited to the above-mentioned embodiment, but the winding piece 8 is abutted to each connecting portion of the slat S as in the second embodiment shown in FIG. 4, for example. It is also possible to mount it on the outer peripheral surface of the winding drum 3, and in the case where the slat S is connected via the connecting member 9 as in the third embodiment shown in FIG. It can also be used as a take piece.

[Advantages] In short, since the present invention is constructed as described above, the outer circumference of the winding cylinder has one roll while the shutter curtain is wound and stored in a polygonal shape on the winding cylinder. A plurality of winding pieces that contact the eye slats or their connecting portions to position the first winding slats are fixed to each of the connecting portions or to each of the slats. Therefore, it is possible to form a winding cylinder for winding and storing the shutter curtain in a polygonal shape without using a polygonal shape as in the conventional case, and use a highly versatile cylindrical shape. It is possible to reduce the cost by significantly simplifying the manufacturing of the.
