  However, when a maintenance worker who has moved from the landing to the car pulls out the elevator door movement restrictor that is press-fitted into the sill groove from the sill groove, the maintenance worker reaches out from the sill toward the sill. Because there is a need to grasp the landing door movement restriction tool, it is difficult for the maintenance worker who has moved from the landing to the car to release the restriction on the movement of the landing door in the door closing direction.

  According to the present invention, the maintenance worker who has moved from the landing onto the car can easily release the restriction of the movement of the landing door in the door closing direction, and when it is press-fitted into the sill groove, the maintenance worker moves away from the sill groove. The present invention provides an elevator hall door movement restricting tool that can suppress the occurrence of such a situation.

  The elevator door movement restrictor according to the present invention restricts the landing door from moving in the door closing direction by being press-fitted into the sill groove, and is press-fitted between the landing door and the vertical frame of the three-way frame. The stopper body that restricts the movement of the landing door in the door closing direction and the stopper body are provided integrally with the stopper body, and when the stopper body is press-fitted into the sill groove, it is positioned below the landing door in the sill groove. And a disengagement preventing portion for restricting the stopper main body from moving upward.

  According to the elevator landing door movement restrictor according to the present invention, the maintenance worker who moves from the landing onto the car can press the stopper main body between the landing door and the vertical frame of the three-sided frame from above the car. The elevator movement restricting tool can be easily grasped. Thereby, the maintenance worker who moved to the car from the landing can easily release the restriction on the movement of the landing door in the door closing direction. In addition, when the stopper body is press-fitted into the sill groove, the stopper body is restricted from moving upward by the detachment prevention part, so it is possible to prevent the elevator landing door movement restrictor from coming off the sill groove. can do.

Embodiment 1 FIG.
1 is a perspective view showing a landing door movement restricting tool for an elevator according to Embodiment 1 of the present invention, FIG. 2 is a front view showing the landing door movement restricting tool for the elevator shown in FIG. 1, and FIG. 3 is a perspective view of the elevator shown in FIG. It is a side view which shows a landing door movement control tool. In the figure, an elevator hall door movement restricting tool 1 includes a stopper main body 11 and a detachment preventing portion 12 formed integrally with the stopper main body 11.

  The stopper main body 11 has a first press-fit portion 111 having a trapezoidal cross section and a second press-fit portion 112 having a triangular cross section. The first press-fit portion 111 and the second press-fit portion 112 are integrally formed. The first press-fit portion 111 is formed so that the dimension in the width direction decreases as the distance from the second press-fit portion 112 increases. The second press-fit portion 112 is formed so that the dimension in the width direction decreases as the distance from the first press-fit portion 111 increases. In this example, the width direction is the width direction of the elevator landing door movement restricting tool 1 and is the direction of arrow A in FIG.

  The detachment preventing portion 12 is formed in the same trapezoidal shape as the first press-fit portion 111 in cross section. The detachment preventing portion 12 is formed to extend from the first press-fit portion 111 in the longitudinal direction. In this example, the longitudinal direction is the longitudinal direction of the elevator landing door movement restricting tool 1 and is the direction of arrow B in FIG.

  Next, a method for restricting the landing door 200 in the door open position from moving in the door closing direction using the elevator hall door movement restricting tool 1 will be described. First, the case where the elevator hall door movement restricting tool 1 is press-fitted into the threshold groove 301 of the hall threshold 300 to restrict the movement of the hall door 200 in the door closing direction will be described. 4 is a front view showing a state where the landing door movement restricting tool 1 of the elevator of FIG. 1 is press-fitted into the sill groove 301, and FIG. 5 is a state where the landing door movement restricting tool 1 of the elevator of FIG. FIG. The width direction dimension of the front end portion of the first press-fit portion 111 is smaller than the width direction dimension of the sill groove 301 of the landing sill 300. The dimension in the width direction of the base end portion that is the end portion on the second press-fit portion 112 side in the first press-fit portion 111 is slightly larger than the dimension in the width direction of the sill groove 301.

  When it is necessary to maintain the landing door 200 in the door open position for a long time, such as when a maintenance worker performs work in the pit, the first press-fitting portion 111 is press-fitted into the sill groove 301. At this time, the first press-fit portion 111 is elastically deformed so that the entire first press-fit portion 111 is disposed in the sill groove 301. The width direction dimension of the base end portion of the first press-fit portion 111 is such that the first press-fit portion 111 has a frictional force that cannot be easily pulled out when the first press-fit portion 111 is disposed in the sill groove 301. And the threshold 300.

  When the first press-fit portion 111 is press-fitted into the sill groove 301, the elevator landing door movement restricting tool 1 is fixed to the sill 300, and is a second part of the stopper body 11 that protrudes upward from the sill groove 301. The press-fitting part 112 hits the door closing direction end of the landing door 200. This restricts the landing door 200 in the door open position from moving in the door closing direction.

  When the first press-fitting part 111 is press-fitted into the sill groove 301, the detachment prevention part 12 is press-fitted into the sill groove 301 so that the entire detachment prevention part 12 enters the sill groove 301. Thereby, the detachment prevention unit 12 is disposed below the landing door 200. By disposing the detachment prevention unit 12 below the landing door 200, the detachment prevention unit 12 hits the landing door 200 from below when the stopper main body 11 moves upward. This restricts the stopper body 11 from moving upward.

  Next, a case will be described in which the elevator hall door movement restricting tool 1 is press-fitted between the hall door 200 and the three-way vertical frame 400 to restrict the movement of the hall door 200 in the door closing direction. FIG. 6 is a plan view showing a state where the landing door movement restricting tool 1 of the elevator of FIG. 1 is press-fitted between the landing door 200 and the three-way vertical frame 400. When the maintenance worker performs work on the car, the second press-fitting portion 112 is press-fitted between the landing door 200 and the three-way vertical frame 400 above the threshold 300. Specifically, the second press-fitting part 112 is press-fitted between the height direction intermediate part or the height direction upper part of the landing door 200 and the vertical frame 400. This restricts the landing door 200 in the door open position from moving in the door closing direction.

  As described above, according to the elevator landing door movement restricting tool 1 according to the first embodiment of the present invention, the maintenance worker who moves from the landing to the car moves the stopper main body 11 between the landing door 200 and the three-way frame. By press-fitting with the vertical frame 400, the elevator landing door movement restricting tool 1 can be easily grasped from above the car. Thereby, the maintenance worker who moved to the car from the landing can easily release the restriction on the movement of the landing door 200 in the door closing direction.

  Further, when the stopper main body 11 is press-fitted into the sill groove 301, the disengagement preventing portion 12 is positioned below the landing door 200 in the sill groove 301, and the stopper main body 11 is restricted from moving upward. Therefore, it can suppress that the landing door movement control tool 1 of an elevator remove | deviates from the threshold groove 301. FIG.

  In the first embodiment, the configuration in which the cross section of the detachment preventing portion 12 is formed in the same trapezoid shape as the first press-fit portion 111 has been described, but the shape of the detachment preventing portion 12 may be other shapes. Good.
