  The panel moving means M1 includes a hinge H that connects adjacent upper surface panels so as to be foldable, a shaft (shaft bar) 11 held by the upper surface panels P1 to P4, and a guide means G1 that guides the shaft 11. . Each of the shafts 11 is disposed at the center in the longitudinal direction of the side edge PE of the top panel P perpendicular to the rotation axis of the hinge H (described later).

  In the present embodiment, the top panel P is composed of four top panels P1 to P4. The upper panel P1 and the upper panel P2 that are adjacent to each other are connected to a hinge H so as to be rotatable. The same applies to the top panel P3 and the top panel P4 adjacent to each other.

  Moreover, in each upper surface panel P1-P4, as shown in FIG. 7, the honeycomb-shaped reinforcement material 22 is accommodated inside the steel plate panel 20 and the flat plate-shaped steel plate panel 21 in side view, and the steel plate The panel 20 and the steel plate panel 21 are fixed by spot welding. That is, the periphery of the reinforcing material 22 is covered with the steel plate panels 20 and 21.

  And as shown in FIG. 6, the rotation mechanism 17 which comprises the hinge H is each adhesive-fixed to the plate-shaped steel plate panel 21 adjacent to each other, and the L-shaped bracket 19 is each adhere | attached on each rotation mechanism 17, A U-shaped steel plate 18 is fixed to the two L-shaped brackets 19 with screws so as to connect the L-shaped brackets 19 to each other. With this configuration, as described above, the top panel P1 and the top panel P2, and the top panel P3 and the top panel P4 are rotatable around the hinge H.

  With this configuration, when the shaft 11 is guided by the guide rail 7 and the upper surface side of the car exterior K is opened, each upper panel P is folded by the hinge H and is laterally (direction perpendicular to the vertical direction of the car). Can be brought close to one end side of the guide rail 7.

(Function, effect)
FIGS. 8A to 8D are side views for each process illustrating the car exterior opening and closing process in the first embodiment. Hereinafter, with reference to FIG. 8, the operation | movement and effect which open the upper surface side of the car exterior K by moving the upper surface panels P1-P4 and ensure the inspection space S1 on a car are demonstrated.

  For the upper panels P1 to P4 (see FIG. 8A) in the closed state, a folding force is applied to the upper panels P1 and P2 and a folding force is applied to the upper panels P3 and P4 (FIG. 8B). reference). As a result, as shown in FIG. 8C, the top panels P1 and P2 are folded and overlapped in the lateral direction (longitudinal direction of the guide rail 7). The same applies to the top panels P3 and P4.

  Then, the folded upper surface panels P1 and P2 and upper surface panels P3 and P4 are moved to one end side E1 (for example, the depth direction side) of the guide rail 7 (see FIG. 8D). As a result, a worker can perform an inspection while ensuring a wide inspection space S1 on the car. Moreover, when the upper panel P is opened, as shown in FIG. 8D, the four upper panels P1 to P4 are overlapped in the horizontal direction. Therefore, the upper end position of the upper panel when the upper panel P is opened is significantly lower than that of the conventional example in which the upper panel is composed of one sheet. Therefore, the possibility that the top panel P interferes with a member outside the panel (such as a car-mounted device) can be greatly reduced.

  In the present embodiment, the shaft 11 is disposed at the center in the longitudinal direction of the top panel P. Accordingly, the center of rotation of the top panels P1 to P4 when the top panels P1 to P4 are folded or spread around the hinge H is the longitudinal center of the side edge PE of the top panels P1 to P4. Therefore, the configuration is such that the guide rail 7 is not provided and the hinge H is folded, and the pivot radius of the top panels P1 to P4 is halved compared to the case where the pivot center of the top panel is the longitudinal end of the top panel. The possibility that the upper panel interferes with members outside the panel can be further reduced.

  After moving to one end E1 to secure the car inspection space S1 and finishing the inspection, the top panels P1 to P4 are moved to the other end E2 (for example, the entrance / exit direction side) to widen the car. Of course, it is possible for an operator to check the inspection space S2 (see FIG. 8D).

  Moreover, according to the dimension and arrangement position of the member outside a panel, deciding the direction which the upper surface panels P1-P4 move along the guide rail 7 to one side, or changing the arrangement direction of the guide rail 7 ( For example, the direction may be changed in a direction orthogonal to the guide rail 7 of the present embodiment. Thereby, a possibility that an upper surface panel may interfere with the member outside a panel can be reduced efficiently.

And a coupling means C for coupling the upper panel P3 and the upper panel P4. In the present embodiment, as the coupling means C, butterfly bolts 24 (bolts that can be rotated by a finger with an operator) attached to one upper panel P (P1, P3) and formed with a male screw, and the other upper panel P (P2, P4) and a screw hole portion N to which the butterfly bolt 24 is screwed.

  The butterfly bolt 24 is attached to one upper panel P (P1, P3) at the end opposite to the hinge H, and the screw hole N is opposite the hinge H to the other upper panel P (P2, P4). It is formed at the end of the side. And the C bending steel plate reinforcement part 29 is formed in the edge part of one upper surface panel P (P1, P3), and the butterfly volt | bolt 24 has penetrated the insertion hole formed in the C bending steel plate reinforcement part 29. Yes. Further, cushion rubber 23 is provided as a cushioning material at the end of the other upper panel P (P2, P4), and the upper panels are prevented from colliding with each other when the upper panels are folded. .

  Thus, in this embodiment, after folding one upper surface panel P1 and the other upper surface panel P2, and one upper surface panel P3 and the other upper surface panel P4, the two panels are joined so as not to open carelessly. Both panels are connected to each other by means C. Therefore, even if an operator accidentally touches the upper panel P, the connected two panels do not open. In addition to the effects achieved in the first embodiment, the worker performs a more safe and reliable inspection on the car. There is also an effect that it is possible.
