DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slat of a shutter installed at an opening of an entrance or the like of a building, and more particularly to a slat of a shutter having a panel member and a connecting member between opposing members. It relates to a shutter slat called a panel shutter.

[0002]

2. Description of the Related Art Japanese Patent Publication No. 4-55186 discloses a shutter slat of this type. A panel member having a fitting edge to be fitted with the fitting groove is supported between the upper and lower crosspieces, and further, a connecting bar fitting groove is formed on one side surface of the upper and lower crosspieces, and the connecting bar materials are fitted at upper and lower ends. A connecting bar formed with a fitting projection that fits with the groove is supported between the upper and lower bars,
A shutter slat is disclosed in which a width determining member for regulating the position of the connecting bar in the left-right direction is fitted in the connecting bar fitting groove adjacent to the connecting bar.

[0003]

However, according to the above prior art, since the panel material fitting groove and the connecting bar material fitting groove are formed separately in the upper and lower rails, the assembling work of the shutter slats can be performed. In addition to being complicated, the cross-sectional shape of the crosspiece is increased due to the complicated shape of the crosspiece, and the area of the panel material cannot be increased to deteriorate the appearance. Furthermore, since the connecting bar is supported on one side surface of the upper and lower bars, the load applied to the shutter slats cannot be effectively received, and it has been difficult to withstand long-term use.

[0004]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve such a problem, and as a result, two bar members are disposed to face each other, and a panel member is provided between the two bar members. In the shutter slat for supporting the connecting bar, a fitting groove is formed on the opposite side of the bar so as to face each other, and a fitting edge for fitting the fitting groove is formed on both side ends between the both bars. A width determining member for fitting a connecting bar having panel material holding portions formed on both side edges into a fitting groove of the bar, and forming a panel holding portion and restricting movement of the connecting bar in the longitudinal direction of the bar. Is fitted in the fitting groove adjacent to the connecting bar, the both ends of the panel material are fitted in the fitting groove, and the panel material is arranged between the connecting bar adjacent to the connecting bar. The intended problem has been solved by being supported by the panel holding portion of the connecting beam and the panel holding portion of the width determining material.

In carrying out the present invention, there are provided a joint member having connecting bars formed with fitting edges on both sides, and a frame member fixed to an intermediate portion of the joint member and having panel material holding portions formed on both side edges. Since the fitting edge of the connecting bar and the panel material holding portion can be manufactured separately, the shapes of the joint material and the frame material can be simplified, and the manufacturing of the connecting bar can be achieved. Becomes easy.

In practicing the present invention, the connecting portion exposed to the outside is formed by making the middle portion of the joint material thinner than the fitting edge and sandwiching the middle portion of the joint material with the frame material divided into two. The thickness of the frame member can be reduced, and a shutter slat with good appearance can be provided.

[0007]

According to the present invention, fitting grooves are formed on opposing side portions of opposed crosspieces, fitting edges for fitting with the fitting grooves are formed on both side ends, and panel materials are formed on both side edges. The connecting bar having the holding portion is supported between the two bars, the width determining member having the panel holding portion is fitted in the fitting groove, and both ends of the panel material are fitted in the fitting groove. Panel materials are arranged between adjacent connecting bars,
Since the periphery of the panel material is supported by the panel holding portion of the connecting bar and the panel holding portion of the width determining member to form the shutter slat, the same fitting groove formed by the panel material and the connecting bar on the bar is provided. Therefore, there is no need to provide a separate fitting groove, so that the shape of the crosspiece can be simplified and the work of assembling the shutter slats can be simplified. Furthermore, since the connecting bar is fitted and supported in the fitting groove formed on the opposite side portion of the facing bar, the load applied to the shutter slat can be effectively received by the connecting bar, and the It can be used.
