The door closer 30 incorporates a spiral spring and is connected to the connecting plate 26a via a wire 32 having one end connected to the spiral spring, and always biases the door panels 12 and 14 in the door closing direction.

  As shown in FIG. 1, door shoes 40, 41 are attached to the left and right ends of the door panel 12 via support plates 60, 62, as shown in FIG. 1. The door shoes 40 and 41 slide in the threshold groove G when the door panel 12 moves in the door closing direction or the door opening direction. This reduces the shaking of the door panel 12 when the door is opened or closed, and prevents the door panel 12 from coming off the sill.

  The left door shoe 41 as viewed from the hoistway is a door shoe with a stopper function according to an embodiment of the present invention. Subsequently, the door shoe 41 will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view showing the overall configuration of the door shoe 41. FIG. 3 is a partially enlarged view showing a state in which the door shoe 41 is viewed from the direction A shown in FIG. As shown in FIGS. 2 and 3, the door shoe 41 includes a shoe main body 42, and a stopper 44 that is provided at a lower portion of the shoe main body 42 and is pivotally supported on the shoe main body 42 so as to be rotatable in the sill groove G. ing. The above-described support plate 60 is fixed to the shoe main body 42 in a state where the support plate 60 is inserted into the central portion. Fixing holes 60 a and 60 b for fixing to the door panel 12 are provided on the upper portion of the support plate 60.

  As shown in FIG. 2, the shoe main body 42 is formed in a boat shape and is provided with a shaft hole 42 a through which a support shaft 46 described later is inserted. The door shoe 41 includes a support shaft 46 that pivotally supports the stopper 44 on the door shoe 41. The lower end of the support shaft 46 is fixed to the stopper 44, and the upper end of the support shaft 46 passes through the shaft hole 42 a of the shoe main body 42 and protrudes from the upper portion of the shoe main body 42.

  With the above configuration, the stopper 44 is rotated relative to the shoe main body 42 from the non-locking position shown in FIGS. Moves to the locked position where it contacts the inner wall of the sill groove G. Thus, the slide of the door shoe 41 can be locked by moving the stopper 44 to the lock position. In this locked position, the lock end 44 a of the stopper 44 abuts against the inner wall of the sill groove G to prevent the door shoe 41 from moving.

  An operation arm 48 extending in the horizontal direction is provided at the upper end of the support shaft 46 described above. Accordingly, the maintenance staff can turn the stopper 44 to the unlocked position or the locked position. Further, a substantially columnar fixing portion 49 protruding downward is provided at the tip of the operation arm 48. As shown in FIG. 3, the operation arm 48 is disposed so as to be slightly inclined with respect to the sliding direction. The door shoe 41 can be fixed at the lock position by engaging the fixing portion 49 with the fixing hole 42b formed on the upper surface of the shoe main body 42. Instead of providing the fixing portion 49 in the shoe main body 42, a magnet is built in the lock end 44a, and the stopper 44 is fixed to the inner wall of the sill groove G by the attractive force of the magnet.

  The stopper 44 described above is provided with engaging claws 51 and 52 at both ends in the sliding direction. Here, since the structures of the engaging claws 51 and 52 are the same, only the engaging claws 52 will be described. The engaging claw 52 is a plate-like member having a window portion 52a formed on the upper side. On the other hand, the bulging part 54 which has elasticity is provided in the end surface in the sliding direction of the shoe main body 42. The stoppers 44 can be fixed to the shoe main body 42 in an aligned state by engaging the window portions 52a of the engaging claws 52 with the bulging portions 54. Instead of providing the engaging claws 51 and 52, when the stopper 44 is fixed to the shoe main body 42 in an aligned state, the support shaft 46 penetrates in the radial direction at a position slightly above the upper surface of the shoe main body 42. A through hole may be provided, and a stopper pin may be inserted into the through hole so that the stopper 44 does not fall downward.

  Here, FIG. 4 is a perspective view showing a state in which the engagement between the shoe main body 42 and the stopper 44 is released and the stopper 44 is moved downward. As shown in FIG. 4, the lower end portion of the above-described support plate 60 protrudes downward from the shoe main body 42. On the other hand, a long groove 44 b into which the lower end portion of the support plate 60 is fitted is provided on the upper surface of the stopper 44. In this way, the lower end portion of the support plate 60 is fitted into the long groove 44b, so that the stopper 44 can be positioned in an aligned state with the shoe main body 42. When the support shaft 46 is pushed down, the window portion 52a is disengaged from the bulging portion 54, the stopper 44 is lowered from the shoe main body 42, and the stopper 44 can be rotated around the axis of the support shaft 46.
