Description

  The present invention relates to a floor joint device for communicating passages of left and right buildings provided through joint portions.

  Conventionally, this kind of floor joint device covers both sides of the opening for the cross passage formed in the outer wall of the external passage of one building, and is attached to the outer wall so as to be slidable in both directions. One end is fixedly or pivotably attached to the slide side wall and the opening end side of this external passage side slide side wall, and the other end communicates with the transition passage opening via the joint. A side wall of the crossing passage side slidably attached to both sides of the crossing passage provided so as to protrude from the other building, and one end portion is slidably supported on the floor surface of the crossing passage, and the other end portion The joint plate is slidably supported on the floor surface of the external passage, and one end portion is pivotally supported in a substantially central portion of the slide passage side wall on the external passage side so as to be turnable in the left-right direction, and the other end portion is the crossover. Almost the floor of the passage The joint is provided with an operating shaft attached to the center so as to be slidable in the front-rear direction, and a pivot pin at one end attached to the slide side wall of the external passage and the other end attached to the floor of the transition passage. The joint plate which pivotally supports the substantially central portion of the plate so as to be pivotable is constituted by a central maintaining mechanism which can always be positioned at the substantially central portion.

The floor joint device constructed in this way has a complicated structure, increases costs, and has the disadvantage that the cover plate becomes large when the amount of movement of the joint plate is set large, and the rigidity of the cover plate must be increased. there were.
