It has become. And when the upper part of the 1st structure A1 and the 2nd structure A2 shifts up and down by the load which a ship receives, and the shake of a ship in the closed lock state concerned, via the door main body 1 on the 1st structure A1 side. The horizontal roller 81 connected in this manner slides between the guide members 70 and 71 connected to the second structure A2 side, and the support shaft 80 and the door body 1 move up and down with respect to the bearing member 7. Further, the upper guide 4 connected to the first structure A1 side via the door body 1 moves up and down with respect to the second rail body 2B connected to the second structure A2 side. That is, since the bearing member 7 and the door main body 1, and the second rail body 2B and the upper guide 4 are allowed to move up and down, the relative movement of the first structure A1 and the second structure A2 is allowed. Can absorb vertical shift.

  Further, in the closed lock state, when the upper portions of the first structure A1 and the second structure A2 are shifted to the left and right and these distances change, the horizontal roller 81 connected to the first structure A1 side is The support shaft 80 and the door body 1 are shifted to the left and right (traveling direction) with respect to the bearing member 7 by moving forward and backward in the guide members 70 and 71 connected to the two-structure A2 side. Further, the upper guide 4 connected to the first structure A1 side moves to the left and right with respect to the second rail body 2B connected to the second structure A2 side. That is, since the bearing member 7, the door main body 1, and the second rail body 2B and the upper guide 4 are allowed to move in the left and right directions, the relative movement of the first structure A1 and the second structure A2 Can absorb left and right shifts.

  Furthermore, in the closed lock state, when the upper parts of the first structure A1 and the second structure A2 are displaced inward and outward, the support shaft 80 and the door body 1 connected to the first structure A1 side are The guide members 70 and 71 connected to the A2 side swing inward and outward about the rotation axis of the horizontal roller 81. Furthermore, the upper guide 4 connected to the first structure A1 side moves in and out between the upper side rails 20 and 21 in the second rail body 2B connected to the second structure A2 side. That is, the inner and outer swings of the bearing member 7 and the door body 1 are allowed, and the inner and outer relative movements of the second rail body 2B and the upper guide 4 are allowed. A shift between the inside and outside of the structure A1 and the second structure A2 can be absorbed.

  That is, even when the door body 1 is connected to the first structure A1 via the lock pin 60 and the right wall member B1 in the closed lock state, the door body 1 moves together with the first structure A1. The shaft member 8 is allowed to move the door body 1 vertically and horizontally relative to the bearing member 7 connected to the structure A2 side, and the shaft member 8 allows the second rail body 2B and the upper guide 4 to move vertically and horizontally. Since the internal and external relative movements are allowed, the force applied to the door body 1 from the first structure A1 and the second structure A2 can be released, and the load on the door body 1 can be suppressed.

  On the contrary, after moving the door body 1 to the right side and opening the entrance / exit O, when the lock pin 60 is inserted into the socket 61 by the operation of a hydraulic cylinder (not shown), the holding means 6 causes the door body 1 to move to the first structure A1. The door body 1 can be held in a state where the doorway O is opened.

In addition, while allowing the door body 1 to swing in the inner and outer directions and the vertical and horizontal movements with respect to the bearing member 7, the second structural body A <b> 2 side of the door body 1 is provided via the shaft member 8 and the bearing member 7. Since the end can be maintained in the state supported by the second structure A2, the load on the holding means 6 in the closed lock state can be reduced. The configuration of the bearing member 7 and the shaft member 8 is as long as the door body 1 is swingable in the inner and outer directions, moved in the left-right direction (traveling direction), and moved in the up-down direction with respect to the bearing member 7. It can be changed as appropriate.

  Further, in the present embodiment, the slide door D is arranged vertically with respect to the door body 1 that opens and closes the entrance / exit O of the gap formed between the first structure A1 and the second structure A2 and the entrance / exit O. A pair of upper and lower guide rails 2 and 3 that are arranged and extend in the frontage direction of the entrance / exit O, one or more upper guides 4 that are attached to the door body 1 and guided by the upper guide rail 2, and the door body 1 One or more lower guides 5 attached to the lower guide rail 3 and a lock device for holding the door body 1 in a state where the doorway O is closed.

  The locking device includes a holding means 6 for restricting the movement of the door body 1 relative to the first structure A1, a bearing member 7, and the door body 1 with respect to the bearing member 7 while being inserted into the bearing member 7. A shaft member 8 that permits swinging in the inner and outer directions, movement in the traveling direction, and movement in the vertical direction is provided, and the bearing member 7 is connected to the second structure A2 side, and the shaft member 8 is It is connected to the door body 1 side.

  Furthermore, the upper guide rail 2 includes a first rail body 2A that is connected to the first structure A1 and has a gap between the guide rail 2 and the second structure A2.

  According to the above configuration, in the closed lock state, the first structure A1 and the second structure A2 are displaced in any direction, up and down, right and left, inside and outside, and the door body 1 moves together with the first structure A1. In addition, since the movement of the door body 1 with respect to the bearing member 7 is allowed by the shaft member 8, the above-described deviation can be absorbed. Accordingly, when the portion to which the slide door D is attached is deformed, even if the door main body 1 is held in a state where the entrance / exit O is closed, the load on the door main body 1 can be reduced.

  In the present embodiment, the first structure A1 is disposed on the right side and the second structure A2 is disposed on the left side, but the opposite may be possible. Moreover, in this Embodiment, although the bearing member 7 is connected with the 2nd structure A2 side and the shaft member 8 is connected with the door main body 1 side, the reverse may be sufficient. Moreover, in this Embodiment, when closing the entrance / exit O with the door main body 1, although the bearing member 7 and the shaft member 8 are arrange | positioned at the front side of the advancing direction of the door main body 1, it is good also as arrange | positioning at the rear side. .

  Although preferred embodiments of the present invention have been described in detail above, it should be understood that modifications, variations and changes may be made without departing from the scope of the claims.
