Description

The present invention relates to an elevator operating device that takes hygiene into consideration, and the elevator operating device.

Conventionally, an illuminated push button switch described in Patent Document 1 has been used as an operating device for an elevator.

On the other hand, due to sanitary demands, non-contact elevator registration buttons are known that allow users to operate the elevator without touching the elevator operating device (for example, Patent Documents 2, 3, and 4). These non-contact elevator registration buttons detect call registration operations by passengers in a non-contact manner using distance sensors and photoelectric sensors.

Incidentally, for visually impaired users, etc., an elevator operation device composed of push buttons is easier to use than the non-contact elevator registration button as described above because there is less risk of erroneous operation.

Due to these circumstances, when installing both contactless elevator registration button and push button elevator operating devices in the landing or car, it is more expensive than installing only one of the elevator operating devices. Installation may be difficult as it requires a large installation space.

Therefore, we have developed a contact-type elevator push button that is equipped with a registration notification section that accepts an operation for registering a destination floor in the elevator car and landing, and also notifies that the destination floor has been registered by pressing the button. In some cases, an elevator operating device is installed, which includes a non-contact detection means that is arranged adjacent to a contact-type elevator push button and accepts destination floor registration by non-contact detection of a predetermined operation. For example, Patent Document 5).

However, even with conventional contact-type elevator push-button switches and elevators equipped with non-contact detection means placed adjacent to the contact-type elevator push-button switches, there are limits to how much space can be saved. For example, in cases where there are a large number of stops, there are cases where a contact type elevator push button switch and a non-contact type detection means cannot be arranged due to space constraints.

Therefore, a movable push button, a movable mechanism that moves the push button, and a switch body that is operated in conjunction with the operation of the push button are provided, and the switch body is placed at a predetermined position facing the back of the push button and spaced apart from the push button. In some cases, the elevator operation device is equipped with a non-contact type detection means for detecting when a customer's fingertip reaches a point.

However, it is equipped with a movable push button, a movable mechanism that moves the push button, and a switch body that is operated in accordance with the operation of the push button. In the case of an elevator operation device equipped with a non-contact detection means for detecting when a passenger's fingertip reaches a point, a passenger who wants to make a car call or a hall call using the non-contact detection means can push the button The user may hold his or her fingertip toward numbers, marks, etc. displayed on the display, and the fingertip may come off the detection area of the detection means formed on a part of the surface different from the display, and the fingertip may not be detected by the detection means.

A display section 22 is provided on the surface of the push button 13 on which a destination floor, an open mark, a close mark, and an emergency call mark (telephone, bell, SOS, etc.) are displayed. Further, the push button 13 has a detection area for detecting a user's finger or the like located a predetermined distance away from the push button 13. The detection area is a part of the surface of the push button 13.

FIG. 5 is an end view of the elevator push button switch 7 with a part of the structure omitted. The elevator push button switch 7 includes a button guide 14 fitted into an opening in a top plate 21 and a push button 13 operated by a user.

Further, the elevator push button switch 7 has a printed circuit board 16 at a position facing the back surface of the push button 13. The printed circuit board 16 is fixed to the inner bottom of the case 15 of the elevator push button switch 7 with screws or resin hooks (not shown). On the surface of the printed circuit board 16 facing the back surface of the push button 13, there is a switch body 17 that is turned on when the push button 13 is operated, and a detection means that detects a user's finger or the like located a predetermined distance away from the push button 13. 18, and a plurality of LEDs 19 that emit light to notify that the switch body 17 has been turned on or that the detection means 18 has detected it.

Further, the elevator push button switch 7 includes a prism 23 at a position facing the detection means 18 on the back surface of the push button 13. The prism 23 redirects the beam B (double-dashed line in FIG. 5) emitted from the detection means 18 toward the horizontal direction of the back surface of the push button 13 at an angle of refraction θ ₁ to the upper side of the vertical direction Y (center side of the push button). refract towards.

The refraction angle θ ₁ is determined by setting a detection area P, which will be described later, in front of the center of the display unit 22 in the horizontal direction It is preferable to set the angle to

According to such a configuration, in the elevator operation device 2 equipped with the push button switch 7 integrally provided with the non-contact type detection means 18, the detection area P is set in the horizontal direction X forward from the center of the display section 22. Therefore, it is possible to provide the elevator operating device 2 in which detection failure by the detection means 18 is suppressed.

In the present embodiment (FIG. 5), the prism 23 is provided at a position that is in contact with the back surface of the push button 13 and faces the detection means 18; Alternatively, they may be provided on the printed circuit board 16 at a distance.

FIG. 8 is a schematic circuit diagram of an elevator push button switch used in an elevator operating device according to an embodiment of the present invention. The switch body 17 and the detection means 18 are connected in parallel.

According to such a configuration, since the switch body 17 and the detection means 18 are connected in parallel, it is possible to output a signal in which either one is conductive, and the number of signal wires can be reduced.

In FIG. 5, the switch body 17 is a tact switch, but it may be other known switches such as a micro switch, a rubber contact, or a leaf switch. In addition, in FIG. 5, the detection means 18 is a photoelectric sensor (PHS), but a distance sensor, a super Other known sensors such as a sonic sensor or a millimeter wave sensor may also be used.

Further, the elevator push button switch 7 has a movable mechanism 20 on the back side of the push button 13 that moves the push button 13 in the horizontal direction X. In FIG. 5, the movable mechanism 20 is a plurality of compression springs. A compression spring is arranged between the push button 13 and the case 15. Furthermore, when the push button 13 is not operated, the compression spring is compressed to a predetermined length and applies force to the push button 13 in a horizontal direction X forward. The movable mechanism 20 may be any other known mechanism, such as a link mechanism or rubber, as long as it can move the push button 13 in the X direction.

Further, when the detection means 18 in FIG. 5 is an infrared photoelectric sensor, a part of the surface of the push button 13 is configured to be able to transmit infrared rays.

In this embodiment, the sensitivity of the sensor is adjusted so that objects in a preset detection area P can be detected. Here, FIG. 5 is a schematic diagram showing the positional relationship between the push button 13 and the detection area P. Moreover, in FIG. 5, the detection area P is illustrated with hatching.

As shown in FIG. 5, the detection area P is set to a spatial area that includes a position away from the top plate 21 by a first predetermined distance L1 in the horizontal direction X to a position separated by a second predetermined distance L2 in the horizontal direction X. be done. Further, the detection area P is a spatial area that falls within the range of the projection plane of the push button 13 in the horizontal direction X, and is a space away from the front of the detection means 18 in the horizontal direction X. Thereby, even when the plurality of push button switches 7 of the elevator operation device 2 are installed with narrower intervals between them, erroneous reactions of the detection means 18 can be reduced.

The first predetermined distance L1 is preferably set to 2 cm≦L1≦3 cm. This can prevent the destination floor from being erroneously registered due to the sensor reacting to the user's finger or the like when a visually impaired user gropes for the location of the push button.

Further, it is preferable that the second predetermined distance L2 is set so that 4 cm≦L2≦10 cm. This makes it difficult for the detection means 18 to erroneously detect a part of the passenger's body or belongings when the elevator car 5 is crowded. As a result, when the inside of the elevator car 5 is crowded, it is possible to prevent a passenger's body part or belongings from coming close to the detection area P and erroneously registering the destination floor.

When the detection means 18 detects light shading for a preset time by the user performing a predetermined action such as placing a fingertip over the detection area P , a detection signal is transmitted to the control device 110 (see FIG. 1), The destination floor is registered. Then, when the destination floor is registered, the LED 19 lights up. Thereby, it is possible to notify the user that the destination floor has been registered.

The control device 110 is a computer that performs overall operation control of the elevator 1, and includes a CPU (not shown), a memory, and a storage device (not shown) such as an HDD. The storage device stores various control programs for controlling the drive of the hoist 160, controlling the opening and closing of the car doors 3, 3, etc., for example. When the CPU reads and executes these programs, smooth operation of the elevator 1 by the control device 110 is realized.

In the elevator 1 having the above configuration, the control device 110 also controls the registration of the destination floor of the elevator car 5. A control program related to destination floor registration of the elevator car 5 is stored in the memory of the control device 110, and the CPU reads the control program from the memory to control the destination floor registration of the car 22.

As described above, the elevator operating device 2 according to the present invention includes a movable push button 13, a movable mechanism 20 that moves the push button 13, a switch body 17 that is operated in accordance with the operation of the push button 13, , and a non-contact detection means 18 for detecting when a customer's fingertip reaches a predetermined position spaced from the push button 13 is provided at a position opposite to the back surface of the push button 13, and the detection means 18 detects a direction inclined toward the center of the push button 13 with respect to a direction perpendicular to the surface of the push button 13.

According to such a configuration, in the elevator operating device 2 equipped with the push button switch 7, 107, or 207 that is integrally provided with a non-contact detection means, it is possible to prevent the passenger's finger or the like from touching the center side of the push button 13. Even in the case where the elevator is detected, it can be easily detected by the detection means 18 and 28, and it is possible to provide an elevator operating device 2 in which omission of detection by the detection means 18 and 28 is suppressed.

Further, in the elevator operation device 2 according to the present invention, the detection means 18 and 28 may be photoelectric sensors.

According to such a configuration, the user can reliably detect that infrared rays etc. that have passed through a part of the detection area on the surface of the push button 13 are blocked, and can register the destination floor. It is possible to provide an elevator push button switch 7 that can improve user convenience while suppressing the increase in size of the operating device 2.

Further, in the elevator operation device 2 according to the present invention, the beam B irradiated from the photoelectric sensor (detection means 18) is transmitted to a prism 23 provided between the photoelectric sensor (detection means 18) and the push button 13. Accordingly, it may be bent in a direction inclined toward the center of the push button 13 with respect to a direction perpendicular to the surface of the push button 13 (horizontal direction X).

According to such a configuration, it is possible to reliably irradiate the beam B emitted from the photoelectric sensor (detection means 18) onto the center of the push button 13, and prevent the passenger's finger or the like from touching the center of the push button 13. Even in the case where the elevator is detected, it is easily detected by the detection means 18, and it is possible to provide an elevator operation device 2 in which failure of detection by the detection means 18 is suppressed.

Moreover, the elevator 1 according to the present invention includes the elevator operating device 2.

Note that the elevator operating device 2 including the elevator push button switch according to the present invention and the elevator 1 including the elevator operating device are not limited to the configuration of the above-described embodiments, and may have the above-described effects. It is not limited to effects. Further, it goes without saying that the elevator operating device 2 including the elevator push button switch and the elevator 1 including the elevator operating device may be modified in various ways without departing from the gist of the present invention. For example, it goes without saying that one or more of the configurations, methods, etc. according to the various modification examples described below may be arbitrarily selected and adopted as the configurations, methods, etc. according to the above-described embodiments.

(1) Although the elevator operation device 2 according to the above embodiment has been described as a car operation panel, it goes without saying that the same effect can be obtained even if it is a hall operation panel.

(2) Moreover, although the elevator 1 according to the above embodiment has been described as an elevator with a machine room, it is of course possible to obtain the same effect even if it is an elevator without a machine room.

(3) Furthermore, the elevator operating device 2 according to the above embodiment is configured such that the display section 22 is shown at the same height as the surface of the push button 13. However, the elevator operating device 2 is not limited to such a configuration. For example, the display section 22 may be a raised character (mark).

(4) Further, in the elevator push button switches 7, 107, 207 used in the elevator registration device 2 according to the above embodiment, the switch body 17 and the detection means 18, 28 are connected in parallel. However, the elevator operating device 2 is not limited to such a configuration. For example, the elevator push button switches 7, 107, and 207 may each have an independent circuit configuration in which the switch body 17 and the detection means 18, 28 are independent, and one of them may output a signal indicating conduction.

(5) Furthermore, the elevator operating device 2 according to the above embodiment has a beam B (in FIG. 5 This is a configuration in which the two-dot chain line) is bent toward the upper side in the vertical direction Y (towards the center of the push button) at a refraction angle θ ₁ . However, the elevator operating device 2 is not limited to such a configuration.

For example, in FIG. 6, the detection means 28 may be provided so as to be inclined toward the center of the push button 13 with respect to the direction perpendicular to the surface of the push button 13. Specifically, the detection means 28 irradiates the beam B (two-dot chain line in FIG. 6) on the upper side in the vertical direction Y (the center side of the push button) at an inclination angle θ ₂ toward the back surface of the push button 13. Therefore, the detection means 28 is fixed to the surface of the printed circuit board 16 on the push button 13 side via a spacer 29 for installing the detection means 28 at an angle. The spacer 29 is inclined so as to widen at an angle θ ₂ from above to below in the vertical direction Y.

The inclination angle θ ₂ is the angle at which the beam B passes from the first predetermined distance L1 portion to the second predetermined distance L2 portion of the detection area P set from the center of the display unit 22 toward the front in the horizontal direction X. It is preferable.

According to such a configuration, in the elevator operation device 2 equipped with the push button switch 107 integrally provided with the non-contact detection means 28, the detection area P is set in the horizontal direction X forward from the center of the display section 22. Therefore, it is possible to provide an elevator operation device in which failure of detection by the detection means 28 is suppressed.

Specifically, the reflection plate 30 directs the beam B (double-dashed line in FIG. 7) vertically (including substantially vertically) irradiated from the detection means 18 toward the back surface of the push button 13 up and down at a reflection angle θ ₃ . It is reflected toward the upper side in direction Y (towards the center of the push button). The reflecting plate 30 includes a reflecting part 31 inclined so as to reflect the beam B at a reflection angle θ ₃ and a fixing part 32 for fixing it to the printed circuit board 16 . The reflecting section 31 is arranged in front of the detecting means 18 in the horizontal direction X so as to be inclined toward the center of the push button 13 . The reflective surface of the reflective section 31 is, for example, a mirror surface.

The reflection angle θ ₃ is the angle at which the beam B passes from the first predetermined distance L1 portion to the second predetermined distance L2 portion of the detection area P set toward the front in the horizontal direction X from the center of the display unit 22. It is preferable.

According to such a configuration, in the elevator operation device equipped with a push button switch integrally provided with the non-contact detection means 18, the detection area P is set in the horizontal direction X forward from the center of the display section 22. , it is possible to provide an elevator operating device in which omission of detection by the detection means 18 is suppressed.
