Call attention to the behavior of.

  As shown in FIGS. 2, 3, 5, and 6, the surface plate 20 has a trapezoidal cross-sectional shape orthogonal to the length direction, and has an opening on the lower bottom side of the cross-sectional trapezoidal shape. The cover portion 21 having a covering shape, the stopper 22 that is arranged on one side in the length direction in the cover portion 21 and orthogonal to the length direction of the cover portion 21, are spaced apart in the width direction of the cover portion 21, respectively. A pair of release jig guide portions 23 extending from the stopper 22 to one side in the length direction of the cover portion 21 in parallel to each other and orthogonal to the width direction of the cover portion 21, and the claw portion 13 on one end side of the peripheral wall of the cover portion 21 Corresponding to each of the plurality of guide grooves 14 on the side of the opening edge on both inner side surfaces in the width direction of the peripheral wall of the cover portion 21. And an engaging protrusion 25 formed on the surface. Further, the surface plate 20 is provided with a light transmission part 26 that transmits light from the light emitting part 7. The light transmitting portion 26 is made of, for example, an acrylic plate and is transparent or translucent.

  Here, the opposing surfaces of the stopper 22, the pair of release jig guide portions 23, and the base portion 11 of the opening 24 are flush with each other as shown in FIG. The thickness in the length direction of the cover portion 21 of the stopper 22 is slightly smaller than the gap between the slide guide portion 12 and the claw portion 13. With respect to the width direction of the cover portion 21, the pair of release jig guide portions 23 are arranged inside the opening 24, and the claw portion 13 is arranged inside the pair of release jig guide portions 23. The amount of protrusion from the surface of the base 11 at the tip of the claw 13 is larger than the depth of the opening 24, that is, the gap between the stopper 22 and the base 11. The engagement protrusion 25 is formed to be slidable in the first guide groove 14 a in a direction perpendicular to the surface of the base 11 and to be slidable in the length direction of the base 11 in the second guide groove 14 b. Further, as shown in FIG. 7, the release jig 30 is made into a flat plate having a rectangular cross section in which a steel plate can be inserted into the opening 24.

  In order to attach the door signal device 100 configured as described above to the lower surface of the upper plate 3, first, the back surface of the base 11 is in contact with the lower surface of the upper plate 3, and is arranged along the length direction of the upper plate 3, The base 10 is fastened and fixed to the upper plate 3 with screws or the like, and the base 10 is attached to the upper plate 3. Next, the engaging projections 25 are aligned from below so as to face each of the first guide grooves 14a, and the surface plate 20 is pushed up. As a result, the engagement protrusion 25 is inserted into the first guide groove 14 a to the base 11 side, and the cover portion 21 is in contact with the surface of the base 11.

  Next, the surface plate 20 is moved to the other side in the length direction of the base 10. Therefore, the engaging protrusion 25 moves from the first guide groove 14 a into the second guide groove 14 b and slides inside the second guide groove 14 b to the other side in the length direction of the base 10. At this time, the stopper 22 moves while pressing the claw portion 13 along with the movement of the surface plate 20 to the other side in the length direction. Thereby, the nail | claw part 13 is elastically deformed so that the front end side may approach the surface side of the base part 11. FIG. When the stopper 22 exceeds the tip of the claw portion 13, the claw portion 13 is restored, and the stopper 22 is inserted between the claw portion 13 and the pair of slide guide portions 12. Thereby, the movement of the base part 11 of the surface plate 20 in the length direction is restricted. Further, the engagement protrusion 25 is fitted into the second guide groove 14b, and movement in the direction orthogonal to the surface of the base 11 of the surface plate 20 and the width of the base 11 is restricted. Thereby, the surface plate 20 is attached to the base 10, and the door signal device 100 is attached to the upper plate 3.

  Then, at the time of maintenance and inspection of the door signal device 100, a rectangular flat plate-like release jig 30 is inserted from the opening 24, as shown in FIG. As shown in FIG. 7B, the release jig 30 is guided to the surface of the release jig guide portion 23 that faces the base portion 11, and presses the claw portion 13 to elastically deform the base portion 11. Move to the other side of the length direction. When the release jig 30 approaches the stopper 22, the tip of the claw portion 13 is displaced toward the base 11, and the restriction on the movement of the stopper 22 to one side in the length direction is released. Therefore, as shown in FIG. 7C, the surface plate 20 is moved to one side in the length direction of the base 11. Thereby, the engagement protrusion 25 moves from the second guide groove 14b into the first guide groove 14a. Next, the surface plate 20 is moved downward and removed from the base 10. Therefore, maintenance inspection of the door signal device 100 is performed.

  As described above, according to the first embodiment, since the claw portion 13 is integrally formed with the base portion 11, the claw portion 13 is moved to the base portion 11 at a position off the insertion path of the release jig 30 using screws or the like. There is no need to install. Therefore, an increase in the width dimension of the base 10 is suppressed, the door signal device 100 can be attached without protruding from the upper plate 3, and the design is improved.

  The stopper 22 moves while elastically deforming the claw portion 13 as the surface plate 20 slides. When the stopper 22 exceeds the claw portion 13, the claw portion 13 is restored, the stopper 22 is inserted between the claw portion 13 and the slide guide portion 12, and the surface plate 20 is restricted from moving in the length direction. Mounted on the base 10. Further, the release jig 30 is inserted from the opening 24, the claw portion 13 is elastically deformed, the restriction of the movement of the stopper 22 is released, the surface plate 20 is moved to one side in the length direction, and the base 10 Can be removed from. Therefore, the operator can reach the upper plate 3 side from the inside of the landing doorway 1 and attach / detach the surface plate 20 to / from the base 10, so that the maintenance and inspection workability of the door signal device 100 is improved.

  The door signal device 100 can be attached by fixing the base 10 to the upper plate 3 with screws or the like. Further, the release jig 30 is inserted through the opening 24 formed in the surface plate 20 to release the restriction on the movement of the stopper 22. Therefore, when the door signal device 100 is attached to the existing elevator platform, there is no additional installation work involving cutting of the upper plate 3 or the wall, and the installation cost can be reduced.

  A pair of slide guide portions 12 are arranged at a predetermined distance from the claw portions 13 to the other side, and end surfaces on one end side of the pair of slide guide portions 12 cooperate with the claw portions 13 to restrict the movement of the stopper 22 Therefore, it is not necessary to newly provide a wall portion for restricting the movement of the stopper 22 in cooperation with the claw portion 13, and the configuration of the base 10 can be simplified.

  A fixing component such as a screw for fixing the base 10 is covered with the surface plate 20 and cannot be seen from the outside. Moreover, the release jig | tool 30 is inserted from the opening part 24, and the restriction | limiting of the movement of the stopper 22 is cancelled | released. Therefore, since the front plate 20 cannot be easily removed, theft and mischief can be suppressed.

  With respect to the width direction of the cover portion 21, the pair of release jig guide portions 23 are arranged inside the opening 24, and the claw portion 13 is arranged inside the pair of release jig guide portions 23. Therefore, when the width of the release jig is smaller than the distance between the pair of release jig guide portions 23, even if the release jig is inserted from the opening 24, such a release jig is not the inclined surface of the claw portion 13. The claw portion 13 cannot be elastically deformed by moving in a direction away from the base portion 11 while being guided by the movement. That is, when the width dimension of the release jig 30 is larger than the interval between the pair of release jig guide portions 23 and equal to or less than the width of the opening 24, the release jig 30 is moved by the pair of release jig guide portions 23. A force for pressing the claw portion 13 can be generated. Therefore, unless the dedicated release jig 30 is used, the surface plate 20 cannot be removed, and the occurrence of theft or mischief can be suppressed.

  Here, by making the opening shape of the opening 24 substantially coincide with the cross-sectional shape of the release jig 30, the release jig 30 can be further specialized. For example, if the groove is formed on one surface of the release jig so as to extend in the length direction, and a protrusion that engages with the groove is formed in the opening 24, the release jig having a simple rectangular cross section can be inserted from the opening 24. Therefore, theft and mischief can be suppressed.
