Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for connecting a hanger rail such as a partition panel.

[0002]

2. Description of the Related Art A partition panel is a panel for appropriately partitioning an indoor space by pulling out a large number of panels along a hanger rail arranged on a ceiling surface and calling them together.

A hanger rail for such a partition panel is constructed by connecting a plurality of rail members with a connecting device. The connection device includes the following. FIG.
In the connecting device shown in (1), in the connecting portion of the hanger rail 1, the connecting pins 3 are fitted and inserted into the connecting holes 2 provided on both sides of the opening of the hanger rail 1 to position each hanger rail 1 in the sectional direction. .

In the connecting device shown in FIG. 14, a flat plate 6 is fitted between the upper side and a locking piece 5 formed below the connecting part of the hanger rail 4 so that each hanger rail 4 cross-sections. Be positioned at.

In the connecting device shown in FIG. 15, a spring member 8 to be crimped is fitted into the inner surface of the hanger rail 7 at the connecting portion of the hanger rail 7, and each hanger rail 7 is positioned in the sectional direction.

[0006]

In the connection device shown in FIG. 13, the work of inserting the two connecting pins 3 into the connecting holes 2 is complicated, and the connecting pins 3 are easily inserted into the connecting holes 2. Therefore, a predetermined clearance is required between the connecting pin 3 and the connecting hole 2. Then, the clearance causes the connected hanger rail 1 to shift in the cross-sectional direction. Therefore, there is a problem that the runner cannot be smoothly guided in the hanger rail 1 due to the displacement at the connecting portion of the hanger rail 1.

The connection device shown in FIG. 14 also has a similar problem because a predetermined clearance is required to insert the flat plate 6 above the locking piece 5. In the connection device shown in FIG. 15, the spring pressure of the spring member 8 needs to be increased in order to reduce the displacement of the hanger rail 7 in the cross-sectional direction, but the spring member 8 can be easily inserted into the hanger rail 7. In order to do so, the spring pressure cannot be made sufficiently strong. Then, when fixing the hanger rail 7 to the mounting surface with screws,
The spring member 8 loses the tightening force of the screw, and the connected hanger rail 7 is displaced. Therefore, there is a problem similar to that of the connecting device shown in FIGS. 13 and 14.

An object of the present invention is to provide a hanger rail connecting device which can easily connect the hanger rails and can prevent the displacement in the sectional direction.
