- the vertical portion 13b of the second shielding plate 13 does not block the first optical axis 16a.
- the protruding portion 13d of the second shielding plate 13 maintains a state where the second optical axis 16b is blocked.
- the vertical portion 13b of the second shielding plate 13 blocks the first optical axis 16a. In this case, both the lower light receiver 15a and the upper light receiver 15b do not receive light. In this state, the door control device determines that the door panel 6 is fully closed.
- the light receiving state of the position switch 11 differs between when the door panel 6 is fully opened and when it is fully closed. For this reason, with one position switch 11, it is possible to determine whether the elevator door is fully open or fully closed. That is, it is possible to determine whether the elevator door is fully open or fully closed with an inexpensive system.
- the protruding portion 13d of the second shielding plate 13 is formed wider in the opening / closing direction of the door panel 6 than the vertical portion 13b. For this reason, even if the second shielding plate 13 is attached somewhat obliquely, the protruding portion 13d always blocks the second optical axis 16b when the vertical portion 13b blocks the first optical axis 16a. For this reason, a highly reliable system that prevents erroneous determination of the position of the door panel 6 can be obtained.
- the protruding portion 13 d of the second shielding plate 13 protrudes to the center side of the door panel 6. For this reason, the distance between the outer sides of the first shielding plate 12 and the second shielding plate 13 can be minimized. Thereby, even if it is the structure which the 2nd shielding board 13 protrudes from the door pocket side of a door apparatus at the time of fully opening the door panel 6, the protrusion amount can be minimized. That is, the influence of the second shielding plate 13 on the required frontage dimension of the hoistway can be reduced.
- the light receivers 15a and 15b direct the light receiving surface toward the cage side. That is, the light receiving surfaces of the light receivers 15a and 15b face the opposite side of the hole. For this reason, disturbance light, such as sunlight, can be prevented from entering the light receivers 15a and 15b directly. Thereby, the erroneous determination of the position of the door panel 6 can be prevented.
- the position of the first shielding plate 12 and the position of the second shielding plate 13 may be reversed.
- the second shielding plate 13 blocks the first optical axis 16a and the second optical axis 16b.
- the first shielding plate 12 blocks only the first optical axis 16a. Even with such an arrangement of the first shielding plate 12 and the second shielding plate 13, the same effect as in the first embodiment can be obtained.
- the position switch 11 may be a projector / receiver using light reflection.
- the projector and the light receiver are disposed on the same side with respect to the shielding plate. The light emitted from the projector is reflected by the shielding plate and accepted by the light receiver. If the door control device determines the position of the panel door 6 based on the light receiving state of the light receiver, the same effect as in the first embodiment can be obtained.
- FIG. 6 is a perspective view of a position switch used in an elevator door device according to Embodiment 2 of the present invention.
- FIG. 7 is a cross-sectional view of a position switch used in an elevator door device according to Embodiment 2 of the present invention.
- symbol is attached
- the first holding part 11a is formed wider in the opening / closing direction of the door panel 6 than the second holding part 11b. At least the first holding part 11 a is formed with a property that suppresses the reflection of the disturbance light 18.
- the surface of the first holding unit 11a is colored black.
- a concave portion is formed on the inner surface of the second holding portion 11b.
- the light receivers 15a and 15b are attached to the bottom surface of the recess. Thereby, the light receivers 15a and 15b are disposed so as to be retracted from the inner surface of the second holding portion 11b.
- the light receivers 15a and 15b are arranged so as to be retracted from the inner surface of the second holding part 11b. For this reason, disturbance light 18 such as sunlight can be prevented from directly entering the light receivers 15a and 15b. For this reason, erroneous determination of the arrangement of the door panel 6 due to the disturbance light 18 can be prevented.
- the first holding portion 11a of the position switch 11 is formed wider in the opening / closing direction of the door panel 6 than the second holding portion 11b. For this reason, the disturbance light 18 reflected by the digit 1 or the like can be blocked by the side edge portion of the first holding portion 11a from entering the light receivers 15a and 15b. Furthermore, at least the first holding portion 11 a is formed with a property that suppresses the reflection of the disturbance light 18. That is, the reflection of the disturbance light 18 at the first holding unit 11a is suppressed. For this reason, erroneous determination of the position of the door panel 6 can be prevented.
- FIG. FIG. 8 is a perspective view of a position switch used in an elevator door device according to Embodiment 3 of the present invention.
- symbol is attached
- the display device 19 is provided on the outer surface of the cage of the second holding portion 11b of the position switch 11.
- the display device 19 displays the light receiving state of the lower light receiver 15a. For example, the display device 19 lights up or blinks when the first optical axis 16a is blocked.
- the display device 19 displays the light receiving state of the lower light receiver 15a. For this reason, when the door panel 6 is fully opened, the position adjustment between the position switch 11 and the first shielding plate 12 can be easily performed. Further, when the door panel 6 is fully closed, the position adjustment between the position switch 11 and the second shielding plate 13 can be easily performed.
- the operator when adjusting the position of the position switch 11, the first shielding plate 12, and the second shielding plate 13, the operator can easily determine whether the door panel 6 is fully opened or fully closed. For this reason, it is not necessary to distinguish and display whether the door panel 6 is fully open or fully closed. That is, the number of display states and the number of display devices 19 themselves can be reduced as compared with the case where the light receiving states of the lower light receiver 15a and the upper light receiver 15b are determined and displayed. For this reason, the position of the position switch 11, the first shielding plate 12, and the second shielding plate 13 can be adjusted using an inexpensive display device 19.
- the elevator door device can be used for an elevator for determining whether the door is fully open or fully closed.
