Description

The present invention relates to a joint device that closes a joint portion between skeletons provided via a joint portion.

Conventionally, a joint device that closes joints between wall surfaces and ceilings of a skeleton can, for example, connect joint plates in a folding screen shape with connecting metal fittings, and the left and right skeletons swing in the left-right direction to absorb changes in the width of the joints. A joint device is known (Patent Document 1).
However, in such a joint device, if the joint portion becomes narrow enough that the connection fittings come into substantially contact with each other, the bearing portion of the connection fitting interferes with the joint plate, so that the joint plate and the connection fitting are damaged. There was a risk of deformation.

Further, in such a connection fitting, the shaft portion of the joint plate must be inserted from the upper end of the joint fitting, and the shaft portion of the joint plate and the bearing portion of the connection fitting must be engaged. Since the metal fittings are formed long in the vertical direction, it was not possible to easily attach / detach the joint plate and the connection metal fittings.
