  • the protrusion 18 may be a portion that protrudes vertically downward from the edge 14 of the slit 12.
  • the sliding portion 11 may have an inclination that descends from the upper surface toward the end portion in the opening / closing direction. That is, the force that the sliding portion 11 presses against the protrusion 18 may be converted into a force that pushes the protrusion 18 upward due to the inclination of the sliding portion 11.
  • FIGS. 10 and 11 are vertical cross-sectional views of the gap shielding portion according to the modified example of the second embodiment.
  • FIG. 10 shows the sill groove cover 9 of the gap shielding portion 7 when the door panel 2 is fully closed.
  • the sill groove cover 9 has an insertion portion 19.
  • the insertion portion 19 is a portion to be inserted into the threshold groove 5.
  • the cross-sectional shape of the insertion portion 19 in the plane perpendicular to the opening / closing direction of the door panel 2 is, for example, a U-shape along the side wall 5a and the bottom surface 5b of the threshold groove 5.
  • the insertion portion 19 connects, for example, the first cover 13a and the second cover 13b. At this time, the insertion portion 19, the first cover 13a, and the second cover 13b may be integrally formed.
  • the insertion portion 19 may be provided over the entire length of the threshold groove cover 9 in the opening / closing direction of the door panel 2. Alternatively, the insertion portion 19 may be provided in a part of the threshold groove cover 9 in the opening / closing direction of the door panel 2. The insertion portion 19 may be provided, for example, at the end of the threshold groove cover 9. The insertion portion 19 contacts at least one of the side wall 5a or the bottom surface 5b of the threshold groove 5. In this example, the insertion portion 19 contacts both the side wall 5a and the bottom surface 5b of the sill groove 5. Further, the insertion portion 19 is arranged between the lower surface of the sliding portion 11 and the bottom surface 5b of the threshold groove 5.
  • the cross-sectional shape of the insertion portion 19 may be, for example, a semi-oval shape or a semi-elliptical shape.
  • FIG. 11 the sill groove cover 9 of the gap shielding portion 7 when the door panel 2 is opened is shown.
  • the edge 14 of the slit 12 of the sill groove cover 9 is in contact with the opposite edge 14 so as to be pressed from above to below by elasticity or the like. At this time, the slit 12 is closed.
  • the height of the edge 14 of the slit 12 is lower than the height of the upper end of the threshold groove cover 9.
  • the sill groove cover 9 receives a frictional force due to contact between the insertion portion 19 and the side wall 5a or the bottom surface 5b of the sill groove 5.
  • the frictional force makes it difficult for the threshold groove cover 9 to move in the horizontal direction and the vertical direction.
  • the sill groove cover 9 is inserted inside the sill groove 5.
  • the position of the slit 12 of the sill groove cover 9 becomes difficult to move with respect to the sill groove 5.
  • the sill groove cover 9 becomes difficult to move in the vertical direction due to the contact between the insertion portion 19 and the side wall 5a or the bottom surface 5b of the sill groove 5.
  • the sill groove cover 9 is fixed to the sill groove 5 without being fastened with screws or bonded with an adhesive, for example.
  • the sill groove cover 9 is less likely to come off from the sill groove 5 in the vertical direction due to contact with the lower surface of the sliding portion 11.
  • the sill groove cover 9 may be fixed to the bottom surface 5b of the sill groove 5.
  • the sill groove cover 9 may be fastened to the bottom surface 5b of the sill groove 5 with screws, for example.
  • the sill groove cover 9 may be adhered to the bottom surface 5b of the sill groove 5 with, for example, an adhesive. As a result, the sill groove cover 9 is more securely fixed to the sill groove 5.

Abstract

L'invention fournit une porte d'ascenseur permettant de concilier prévention de pénétration de matières étrangères dans une rainure de seuil, et blindage contre les fumées dans une partie inférieure de la porte, et fournit également une pièce de maintenance pour porte d'ascenseur. La porte (1) d'ascenseur est équipée d'une partie blindage d'interstice (7). Une partie ou l'ensemble de la partie blindage d'interstice (7) consiste en une pièce de maintenance. La partie blindage d'interstice (7) recouvre par le dessus la rainure (5) d'un seuil (4) lorsqu'un panneau de porte (2) est complètement ouvert. La partie blindage d'interstice (7) obstrue un interstice entre une extrémité inférieure du panneau de porte (2) et le seuil (4) lorsque le panneau de porte (2) est complètement fermé.
