DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevator door open/close confirmation device (hereinafter referred to as an open/close confirmation device) according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The open/close confirmation device is for confirming the open/close state of the elevator door. As shown in FIG. 1, the open/close confirmation device of the present embodiment is configured to confirm the open/closed state of a hall door (hall door) D, and is installed above a hall entrance O in a hoistway. there is

The landing door D includes a door panel D1 and a door hanger D2 attached to the upper end of the door panel D1.

As shown in FIGS. 2 and 3, the open/close confirmation device 1 according to the present embodiment is a switch that can be switched between an ON state in which the electric circuit is closed while being connected to the electric circuit, and an OFF state in which the electric circuit is open. A device 2 and an on/off switching mechanism 3 for switching the open/close state of the switch device 2 are provided.

The switch device 2 includes a pair of fixed terminals 20 whose installation position is fixed, and is arranged in a state in which the pair of fixed terminals 20 electrically connected to the electric circuit and the pair of fixed terminals 20 are arranged at positions facing the pair of fixed terminals 20 . A movable terminal 21 that moves in a contact-separation direction to contact and separate from a pair of fixed terminals 20 , closes an electric circuit by contacting each of the pair of fixed terminals 20 , and separates from at least one of the pair of fixed terminals 20 . a movable terminal 21 configured to open an electric circuit by doing so; a movable portion 22 to which the movable terminal 21 is attached and which moves in the same direction as the direction in which the movable terminal 21 contacts and separates from the pair of fixed terminals 20; It has a case 23 in which the fixed terminal 20 and the movable terminal 21 are housed.

In this embodiment, the direction in which the movable terminal 21 contacts and separates from the fixed terminal 20 is referred to as the contact-separation direction. A direction away from is referred to as a separation direction. Also, the direction corresponding to the direction in which the landing door D opens and closes is referred to as the opening/closing direction.

The fixed terminal 20 has conductivity. Further, the fixed terminal 20 is restricted from moving in the horizontal direction within the case 23 .

The movable terminal 21 has conductivity. Therefore, when the movable terminal 21 comes into contact with each of the pair of fixed terminals 20, the movable terminal 21 is in a conductive connection state in which each of the pair of fixed terminals 20 is electrically connected, and is separated from at least one of the pair of fixed terminals 20. , the pair of fixed terminals 20 are electrically disconnected from each other. When the movable terminal 21 switches to the disconnected state, the switch device 2 opens the electric circuit (off state), and when the movable terminal 21 switches to the conductive connection state, the switch device 2 closes the electric circuit (on state). )become.

The movable portion 22 includes an accommodated portion 220 accommodated in the case 23 and an exposed portion 221 exposed outside the case 23, and is configured such that the exposed portion 221 can be pushed. there is

Although not shown in the present embodiment, the switch device 2 has an urging portion that urges the movable portion 22 in the separating direction. Therefore, when the movable portion 22 receives an external force (pressing force in the direction of approach) exceeding the biasing force, the movable portion 22 moves in the direction of approach, and the movable terminal 21 contacts the pair of fixed terminals 20, thereby moving the movable portion 22. When the external force is removed from the portion 22 , the movable portion 22 moves in the separating direction, and the movable terminal 21 separates from the pair of fixed terminals 20 .

Note that the switch device 2 may be composed of, for example, a microswitch.

The on/off switching mechanism 3 moves the movable portion 22 in the approach direction to approach the fixed terminal 20 as the landing door D closes, and moves the movable portion 22 in the separation direction as the landing door D opens. It is configured to be moved to separate from the fixed terminal 20 .

The on/off switching mechanism 3 of the present embodiment includes a lever 30 disposed so as to face the movable portion 22 in the contact/separation direction (aligned with the movable portion 22 in the contact/separation direction), and the lever 30 is rotatable. a rotation holding portion 31 that holds the platform, a biasing means 32 that biases the lever 30 in the direction of approach, an operating mechanism 33 that operates the lever 30 in accordance with the opening/closing operation of the landing door D, and a base 34. , has

The lever 30 includes a front portion 300 on one end side of the rotation center position C in the longitudinal direction and a rear portion 301 on the other end side of the rotation center position C in the longitudinal direction, and the front portion 300 is movable. It is arranged to overlap the portion 22 (see FIG. 4).

The rotation holding portion 31 is erected on the base 34 . The lever 30 is rotatably attached to the tip of the rotation holding portion 31 .

The biasing means 32 is configured to bias the front portion 300 of the lever 30 toward the approach direction. Further, the position where the biasing means 32 biases the lever 30 is farther from the rotation center position C than the position where the movable portion 22 contacts the lever 30 .

The biasing means 32 of this embodiment is composed of an extension coil spring, one end of which is connected to the rear surface of the front portion 300 of the lever 30 in the direction of expansion and contraction, and the other end of which is connected to the base 34 in the direction of expansion and contraction. It is connected.

Therefore, unless an external force other than the biasing force of the biasing means 32 is applied to the lever 30 , the front part 300 is arranged below the rear part 301 , and the rear part 300 is in a state where the biasing means 32 is applied. When the front portion 300 is pushed downward with a force stronger than the biasing force, the front portion 300 moves upward, and when the pushing operation on the rear portion 301 is released, the front portion 300 moves downward and returns to its original position. ing.

Since the front portion 300 of the lever 30 is arranged to face the movable portion 22 as described above, when no external force is applied to the rear portion 301, the movable portion 22 is pushed in the direction of approach, and the rear portion 301 is pushed. When an external force stronger than the urging force is applied to the movable portion 22, the push operation to the movable portion 22 is released.

Therefore, in the present embodiment, the state in which the movable portion 22 is pushed by the front portion 300 of the lever 30 and the closed state of the switch device 2 are interlocked, and the front portion 300 of the lever 30 pushes the movable portion 22 . is released and the open state of the switch device 2 is interlocked.

A signal flowing through the electric circuit when the switch device 2 is in the on state is treated as a signal indicating that the hall door D is closed.

The operating mechanism 33 pushes the rear portion 301 of the lever 30 downward as the landing door D opens, and releases the lever 30 from pushing the rear portion 301 as the landing door D opens and closes. is configured to

More specifically, the actuation mechanism 33 includes a moving contact portion 330 which is arranged in a position parallel to the rear portion 301 of the lever 30 in the opening/closing direction and is movable in the opening/closing direction. to the rear portion 301 side of the lever 30 in the opening/closing direction, and a second movement operation portion 332 (see FIG. 1) that moves the movement contact portion 330 to the front portion 300 side of the lever 30 in the opening/closing direction. ) and

The moving abutting portion 330 is arranged at a position in which it is horizontally aligned in the opening/closing direction with the rear portion 301 of the lever 30 in a state in which it is not subjected to an external force other than the biasing force of the biasing means 32 . Therefore, when the moving contact portion 330 moves toward the rear portion 301 of the lever 30 relative to the rotation center position C in the opening/closing direction, the movement contact portion 330 interferes with the rear portion 301 of the lever 30, and the front portion of the lever 30 moves toward the front portion of the lever 30 relative to the rotation center position C in the opening/closing direction. It is configured to move away from the rear portion 301 of the lever 30 when moved to the 300 side.

The first movement operation portion 331 is configured to bias the movement contact portion 330 toward the rear portion 301 side of the lever 30 in the opening/closing direction.

The first movement operation portion 331 of the present embodiment includes a housing 3310 provided on the base 34 and an operation shaft portion 3311 inserted so as to be horizontally slidable with respect to the housing 3310. and an operating shaft portion 3311 whose one end in the direction is joined to the moving abutting portion 330, and a shaft portion 3311 protruding outward (outward in the radial direction of the operating shaft portion 3311) from the outer peripheral surface of the operating shaft portion 3311. and an internal biasing means 3313 that is disposed in the housing 3310 and applies a biasing force acting toward the rear portion 301 side of the lever 30 in the horizontal direction to the protrusion 3312 . , has

The operating shaft portion 3311 is biased toward the rear portion 301 by the biasing force of the internal biasing means 3313 via the projecting portion 3312 . Therefore, when the distal end portion (one end portion disposed closer to the lever 30 than the housing 3310) of the operating shaft portion 3311 is pushed in the axial direction (the axial direction of the operating shaft portion 3311), the distal end portion of the operating shaft portion 3311 moves toward the housing. 3310, and when the push operation to the tip is released, the tip automatically moves away from the housing 3310. As shown in FIG.

The second movement operation portion 332 is arranged at a position that is horizontally aligned with the movement contact portion 330 in the horizontal direction. In addition, the second movement operation portion 332 is movable in the horizontal direction in accordance with the opening/closing operation of the hall door D, and is configured to contact the movement contact portion 330 on the side opposite to the operation shaft portion 3311. there is

As shown in FIGS. 1, 5, and 6, the second movement operation portion 332 of the present embodiment comes into contact with the movement contact portion 330 as the landing door D closes, causing the landing door D to close. It is configured to move away from the moving contact portion 330 with the opening operation.

Therefore, when the landing door D is closed, the moving contact part 330 is pushed by the second moving operation part 332 to move toward the front part 300 from the rotation center position C of the lever 30. It is configured to be pushed back by the shaft portion 3311 and move toward the rear portion 301 side of the rotation center position C of the lever 30 .

The configuration of the open/close confirmation device 1 according to this embodiment is as described above. Next, the operation of the open/close confirmation device 1 will be described.

As shown in FIG. 5, when the landing door D is closed, since the rear portion 301 of the lever 30 is not pushed, the front portion 301 of the lever 30 is moved in the approach direction by the biasing force of the biasing means 32 . attracted.

At this time, since the movable portion 22 is pushed by the front portion 300 of the lever 30, the switch device 2 is switched to the ON state.

As shown in FIG. 6 , when the hall door D opens, the second movement operation part 332 moves together with the hall door D and separates from the movement contact part 330 , and the movement contact part 330 pushes the first movement operation part 331 . It is operated and moves toward the rear portion 301 side of the lever 30 .

As a result, when the moving contact portion 330 moves toward the rear portion 301 of the lever 30 from the rotation center position C of the lever 30, the rear portion 301 of the lever 30 is pushed down by the moving contact portion 330, and the front portion 300 of the lever 30 moves. It moves toward the separation direction.

Then, when the pressing operation of the movable portion 22 by the lever 30 is released, the switch device 2 is switched to the OFF state.

When the hall door D is closed again, the second movement operation part 332 moves together with the hall door D and pushes the movement contact part 330, so that the movement contact part 330 moves toward the front part 300 of the lever 30. Moving.

As a result, when the moving contact portion 330 moves toward the front portion 300 of the lever 30 from the rotation center position C of the lever 30 , the pressing operation of the moving contact portion 330 toward the rear portion 301 of the lever 30 is released, and the lever 30 is pulled toward the approach direction.

Then, when the lever 30 pushes the movable portion 22, the switch device 2 is switched to the ON state.

As described above, according to the opening/closing confirmation device 1 of the present embodiment, the movable terminal 21 of the switch device 2 is configured to contact and separate from the fixed terminal 20 while being arranged at a position facing the fixed terminal 20. Therefore, the movable terminal 21 is configured to contact and separate from the fixed terminal 20 without moving in the opening/closing direction of the hall door D. As shown in FIG.

As a result, in the open/close confirmation device 1, when the on/off switching mechanism 3 moves the movable terminal 21 in the contact/separate direction in accordance with the opening/closing operation of the hall door D to open/close the electric circuit, the movable terminal 21 opens/closes the hall door D. Since sliding on the fixed terminal 20 in the direction is suppressed, wear of the movable terminal 21 and the fixed terminal 20 is also suppressed.

Therefore, the opening/closing confirmation device 1 can produce an excellent effect that poor contact is less likely to occur.

In addition, the on/off switching mechanism 3 operates the movable terminal 21 by means of a lever 30 configured to move in the contact/separate direction with the opening/closing operation of the hall door D (in the present embodiment, the movable terminal 21 is operated via the movable portion 22). The lever 30 for moving the movable terminal 21 in the contact/separation direction is also arranged at a fixed position in the opening/closing direction of the landing door D. .

Therefore, when the lever 30 moves, an external force acting in the opening/closing direction of the landing door D is less likely to be applied to the movable terminal 21 . Therefore, in the open/close confirmation device 1, the movement of the movable terminal 21 in the opening/closing direction of the hall door D accompanying the movement of the lever 30 can be suppressed, and wear of the movable terminal 21 and the fixed terminal 20 can be easily suppressed.

Furthermore, in the opening/closing confirmation device 1 of the present embodiment, the lever 30 that moves so as to move the movable terminal 21 toward and away from the fixed terminal 20 is biased toward the approach direction by the biasing means 32 . 21 and the fixed terminal 20 can be easily maintained in contact (a state in which the electric circuit is closed).

In addition, since the opening/closing confirmation device 1 of the present embodiment is configured such that the movable portion 22 can be pushed by the lever 30 simply by releasing the first movement operation portion 331 from the lever 30, the first movement operation portion 331 Even if there is variation in the momentum (movement amount), variation in the pushing amount of the movable portion 22 by the lever 30 is less likely to occur.

It should be noted that the elevator door open/close confirmation device according to the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the present invention.

In the above-described embodiment, the opening/closing confirmation device 1 is configured to confirm the opening/closing state of the landing door D as an example, but the configuration is not limited to this. For example, the open/close confirmation device may be configured to confirm the open/close state of the car door.

In the above embodiment, the biasing means 32 is configured to bias the front portion 300 of the lever 30 in the approaching direction, but is not limited to this configuration. For example, as shown in FIGS. 7 and 8, the biasing means 32 may be configured to bias the front portion 300 of the lever 30 in the separating direction.

As described above, if the biasing means 32 is configured to bias the front portion 300 of the lever 30 in the separation direction, the state in which the movable terminal 21 and the fixed terminal 20 are separated (the electric circuit is open) state) is easier to maintain.

In this case, the operating mechanism 33 operates to move the lever 30 in the approach direction in accordance with one of the closing operation and the opening operation of the landing door D, thereby closing the landing door D. It is sufficient that the operation on the lever 30 is released in accordance with the other operation of the operation or the opening operation.

In the opening/closing confirmation device 1 shown in FIGS. 7 and 8, the operating mechanism 33 operates to move the lever 30 in the approaching direction in accordance with the closing operation of the landing door D, and the other side of the opening operation of the landing door D is operated. The operation of the lever 30 is released with the operation of .

More specifically, the operating mechanism 33 shown in FIGS. 7 and 8 pushes the front portion 300 of the lever 30 from the surface side (upper surface side) as the landing door D closes, thereby opening the landing door D. It is configured to have a moving push-in portion 333 that releases the pushing of the lever 30 into the front portion 300 as the lever 30 moves.

In the opening/closing confirmation device 1 having such an actuation operation mechanism 33, even if the pushing position of the lever 30 by the moving pushing portion 333 (the pushing position in the longitudinal direction) varies, the lever 30 can be reliably pushed to move the movable portion 22. Can be operated by pushing.

7 and 8, the on/off switching mechanism 3 of the open/close confirmation device 1 switches the switch device 2 to the ON state when the landing door D is closed, and switches the switch device 2 to the ON state when the landing door D is open. Since the switch device 2 is configured to switch to the off state, the signal flowing when the switch device 2 is on is treated as a signal indicating that the hall door D is closed.
