Embodiment 1 FIG.
FIG. 1 is an overall view showing an in-car hall of an elevator equipped with an emergency call button device according to Embodiment 1 of the present invention. In FIG. 1, an elevator door 2 is provided in an elevator hall 1. In addition, a plurality of (two in this example) operation panels 3a and 3b that can be called and registered are installed on the wall surface of the car hall 1. Here, the operation panels 3a and 3b indicate in-car operation panels installed in the car.

  In this example, the operation panel 3 a is installed on the side of the door 2 on the surface where the door 2 is provided in the car. Further, the operation panel 3b is installed on a wall different from the surface on which the door 2 is provided in the car. The operation panels 3a and 3b are respectively provided with a display board 4 for displaying the operation status of the car, a call registration unit 5 for a user to perform call registration, and an emergency call button device 10 operated when the elevator is abnormal. .

  FIG. 2 is an enlarged view showing the emergency call button device 10 of FIG. FIG. 3 is a side view showing the emergency call button device 10 of FIG. FIG. 4 is a cross-sectional view taken along line IV-IV of the emergency call button 10 of FIG. Hereinafter, the configuration of the emergency call button 10 will be described with reference to FIGS.

  As shown in FIGS. 2 to 4, the emergency call button device 10 includes an emergency button unit 20, a cover 30 that prevents the emergency button unit 20 from being abused and erroneously operated, and the cover 30 between a closed state and an open state. And an opening / closing mechanism 40 that can be displaced.

  The emergency button portion 20 is inserted into a button hole provided in the operation panels 3a and 3b. Here, the button holes provided in the operation panels 3 a and 3 b are made in accordance with the size of the emergency button portion 20.

  Further, the emergency button portion 20 includes an emergency button body 21 partially protruding from the surface of the operation panels 3a and 3b facing the car landing 1, and a button frame 22 that supports the emergency button body 21. ing.

  A part of the emergency button body 21 is provided so as to be exposed to the car landing 1. Thus, the user can notify the abnormality of the elevator to the outside by pressing the emergency button body 21 exposed to the car landing 1 with a finger.

  The button frame 22 includes a fixed frame portion 22a provided on the back side of the operation panels 3a and 3b not facing the car landing 1, and a guide frame portion 22b protruding from the fixed frame 22a toward the car landing 1 side. have.

  The guide frame portion 22b protrudes from the fixed frame portion 22a so that the emergency button body 21 surrounds the portion exposed to the car landing 1. That is, a part of the guide frame portion 22b protrudes from the surfaces of the operation panels 3a and 3b. Thereby, when the emergency button main body 21 is pushed by the user, it is guided in the direction away from the car landing 1 along the guide frame portion 22b.

  Further, with respect to the direction in which the emergency button body 21 protrudes into the car landing 1 (the direction of arrow A in FIG. 4), the position of the end of the guide frame portion 22b on the car landing 1 side is within the car of the emergency button main body 21. It is arrange | positioned rather than the position of the edge part at the landing 1 side in the car landing 1 side. This prevents an erroneous operation such as pressing the emergency button body 21 when the user hits the emergency call button device 10.

  Furthermore, in order to prevent erroneous operation with certainty, a cover 30 is provided closer to the car landing 1 side than the emergency button portion 20. The cover 30 is a plate having a shape that can cover the entire surface of the emergency button portion 20.

  Since the cover 30 is in a closed state that covers the entire surface of the emergency button portion 20 at a normal time when no abnormality has occurred in the elevator, the user cannot press the emergency button body 21. Therefore, in order to press the emergency button body 21 in an emergency, the cover 30 needs to be moved to an open state in which the emergency button body 21 can be operated by the opening / closing mechanism 40.

  The opening / closing mechanism 40 is provided on the upper portion of the cover 30 in the cage height direction (the arrow B direction in FIGS. 1 to 4). The opening / closing mechanism 40 includes a vertical rotation mechanism (first rotation mechanism) 50 that allows the cover 30 to rotate in the first rotation direction, and a left-right rotation mechanism that enables the cover 30 to rotate in the second rotation direction. (Second rotation mechanism part) 60.

  The vertical rotation mechanism unit 50 applies an external force that lifts the cover 30 to displace the cover 30 from the closed position corresponding to the closed state to the open position corresponding to the open state. That is, the first rotation direction is a direction in which the cover 30 moves from the closed position to the open position when an external force that lifts the cover 30 is applied. The vertical rotation mechanism unit 50 includes a bearing 51 attached to the operation panels 3 a and 3 b and a rotating unit main body 52 supported by the bearing 51.

  The bearing 51 includes a pair of bearing main bodies 51 a and 51 b arranged at a distance from each other, and a pair of studs 510 provided on the bearing main bodies 51 a and 51 b and serving as the rotation shaft of the rotating portion main body 52. ing. The stud 510 is provided so as to protrude from the surfaces where the bearing bodies 51a and 51b face each other.

  With respect to the axial direction of bearing main bodies 51a and 51b (the direction of arrow C in FIG. 2), the distance between the ends of bearing bodies 51a and 51b farthest away from each other is longer than the diameter of guide frame 221. . The bearing bodies 51a and 51b are arranged on the operation panel 3a so that the cover 30 can cover the emergency button portion 20, that is, the stud 510 is positioned closer to the car landing 1 side than the emergency button portion 20. 3b. Furthermore, the bearing main bodies 51a and 51b are disposed above the emergency button portion 20 in the height direction of the car.

  The rotating portion main body 52 includes a rotating body 521 that is rotatably provided around the stud 510, and a cover mounting plate portion 522 that is provided on the rotating body 521 and extends along a tangent line of the rotating body 521. Yes.

  The rotating body 521 has a columnar shape having fitting holes that can be fitted to the studs 510 at both ends, and the rotating body 521 can rotate to the studs 510 by fitting the fitting holes and the studs 510 together. Is attached. The length of the rotating body 521 is slightly shorter than the distance between the opposing surfaces between the bearing bodies 51a and 51b. Here, the term “slightly” refers to a size such that the rotating body 521 has a rotatable clearance in the bearing bodies 51a and 51b during rotation.

  The cover attaching plate portion 522 is a plate extending along the lower side of the car 2 from the end portion away from the operation panels 3a and 3b of the rotating body 521 in a normal state. At this time, the cover mounting plate portion 522 has such a length that the lower end portion of the cover mounting plate portion 522 does not cover the upper end portion of the emergency button portion 20 in the height direction of the car.

  The cover mounting plate 522 has a mounting hole 523 in which the cover 30 can be mounted. Corresponding to the mounting hole 523, the mounting hole 31 is also formed in the cover 30. The attachment hole 31 of the cover 30 is provided in the upper part of the cover 30.

  Further, the mounting hole 31 is opened at a position where the position of the upper end of the cover 30 is higher than the position of the stud 510 in the height direction of the car when the cover 30 is mounted on the cover mounting plate 522. Yes. This is because when the cover 30 is lifted and displaced from the closed position to the open position, the upper end portion of the cover 30 interferes with the bearing 51 so that the cover 30 does not exceed a desired movable range. The desired range of motion will be described later.

  The cover 30 is attached to the cover attachment plate part 522 via the left / right rotation mechanism part 60. The left-right rotation mechanism 60 uses a rod-like member (for example, a bolt or a screw) that is passed through the attachment hole 31 of the cover 30 and the attachment hole 523 of the cover attachment plate 522. That is, the left / right rotation mechanism 60 is provided at an attachment position where the cover 30 is attached to the cover attachment plate 522. Here, the left and right rotation mechanism 60 has the cover 30 and the cover mounting plate 522 attached so that the cover 30 can slide along the cover mounting plate 522.

  As a result, the user can apply an external force that causes the cover 30 to slide in the width direction of the cover 30 (the direction of the arrow C in FIG. 2 that coincides with the axial direction of the bearing bodies 51a and 51b) by the user. It is possible to rotate left and right around the mounting hole 31. Here, the left and right are the left and right directions when the user views the operation panels 3a and 3b from the front, and correspond to the direction of arrow E in FIG.

  Accordingly, the cover 30 is rotated left and right around the mounting hole 31 provided in the upper part of the cover 30 by the left and right rotation mechanism 60, so that the cover 30 is supported from the closed position corresponding to the closed state to the open state. It can be displaced to the closed position. That is, the second rotation direction is a direction in which the cover 30 moves from the closed position to the open position when an external force that slides in the width direction of the cover 30 is applied.

  Next, the operation of the emergency call button device 10 will be described. FIG. 5 is a front view showing a state in which the cover 30 is displaced from the closed position to the open position using the vertical rotation mechanism unit 50. FIG. 6 is a side view showing the emergency call button device 10 of FIG.

  The user can push the emergency button body 21 as shown in FIGS. 5 and 6 by lifting the cover 30 in the direction of arrow D in FIG. 6 corresponding to the first rotation direction. At this time, as shown in FIG. 6, the upper end portion of the cover 30 interferes with the bearing 51 (not shown, but actually, the bearing main bodies 51a and 51b). Hereinafter, this position is referred to as an interference position.

  Therefore, the movable range in which the cover 30 can be rotated by the vertical rotation mechanism unit 50 is from the closed position to the interference position. In this example, when the closed position of the cover 30 is 0 degree, the interference position is 90 degrees, and the cover 30 cannot be lifted beyond an angle greater than 90 degrees. Thereby, the cover 30 lifted to the interference position returns to the closed position by its own weight. That is, the desired range of motion described above is a range in which the cover 30 can return from the open position to the closed position by its own weight.

  In this example, the cover 30 cannot be lifted by an angle greater than 90 degrees, but may be an angle greater than 90 degrees as long as the cover 30 can return from the open position to the closed position by its own weight. .

  FIG. 7 is a front view showing a state in which the cover 30 is displaced from the closed position to the open position using the left-right rotation mechanism 60. As shown in FIG. 7, the user can push the emergency button body 21 by rotating the cover 30 in the direction of arrow E in FIG. 7 corresponding to the second rotation direction.

  At this time, since the position of the left-right rotation mechanism 60 serving as the rotation center is provided in the upper part of the cover 30, the cover 30 is moved from the open position to the closed position by its own weight regardless of the open position where the cover 30 is rotated. To come back.

  In the above-described operation, the individual operations of the vertical rotation mechanism unit 50 and the left-right rotation mechanism unit 60 have been described. However, the cover 30 can be combined with the operations of the vertical rotation mechanism unit 50 and the left-right rotation mechanism unit 60 to obtain a plurality of operations. Operation in the direction is possible. That is, the cover 30 is rotatable along the cover mounting plate portion 522 while being lifted.

  In such an emergency call button device for an elevator according to the first embodiment, when the user applies an external force such as lifting to the cover that covers the emergency button portion, the cover can be rotated in the first rotation direction. It has a mechanism part. In addition, in the emergency call button device of the elevator, when the user applies an external force that slides in the width direction of the cover, the cover can be rotated in the second rotation direction. The left-right rotation mechanism 60 is provided.

  By providing such a configuration, even when a user's belongings, in particular, a leash string, is hooked on the cover, the cover can be moved in a plurality of directions combining up, down, left and right. Therefore, even if the user forcibly pulls the belongings caught on the cover, the belongings can be easily removed from the cover. As a result, the effect that the risk of breakage of the cover can be reduced can be obtained.

  Further, in the case of an emergency, a conventional cover that can only rotate in a certain direction has a problem that the user cannot immediately determine how to remove the cover and the operability of the emergency call button device is poor. On the other hand, the emergency call button device for an elevator according to the present invention has a configuration in which the cover can rotate in a plurality of directions. Therefore, the abuse of the emergency button, the prevention of erroneous operation, and the improvement of operability can be achieved at the same time, and the convenience can be improved. As a result, an effect that the abnormality of the elevator can be notified to the outside earlier can be obtained.

  The movable range of the cover by the vertical rotation mechanism is set from the closed position to an interference position that can always return to the closed position due to the weight of the cover. Further, the left-right rotation mechanism is provided on the upper part of the cover, and can always return to the closed position by its own weight regardless of the open position of the cover. As a result, even if the cover is moved to the open position due to mischief, it immediately returns to the closed position, so that an erroneous operation by another user can be prevented.

  In the first embodiment, the emergency call button device 10 is configured integrally with the operation panels 3a and 3b. However, after the emergency call button device 10 is provided separately from the operation panels 3a and 3b, the emergency call button device 10 is provided. The button device 10 may be attached to the operation panels 3a and 3b. At this time, in the emergency call button device 10, the call device fixing plate to which the emergency button portion 20, the cover 30, and the opening / closing mechanism portion 40 are attached is attached to the operation panels 3a and 3b with a fixture.

  In the first embodiment, a plurality of operation panels 3 are provided in the car hall 1, but one operation panel 3 may be provided.

  Further, in the first embodiment, the cover 30 can cover the entire surface of the emergency button unit 20, but the cover 30 may cover a range in which an erroneous operation of the emergency button unit 20 can be prevented. It is not always necessary to cover the entire surface.
