Disclosure of Invention

Problems to be solved by the invention

A car operating panel having braille portions for visually impaired people is considered. When a contactless sensor (contactless button) for specifying a destination floor is provided on such a car operating panel, a visually impaired person can know the destination floor indicated by the braille portion by touching the braille portion, or can estimate the approximate position of the contactless sensor corresponding to the known destination floor.

However, the visually impaired person does not necessarily know the position of the proximity sensor accurately. Therefore, the visually impaired may not be able to detect his or her hand or finger with the proximity sensor corresponding to the requested destination floor or may detect a hand or finger with the proximity sensor corresponding to the wrong destination floor.

Means for solving the problems

Detailed Description

Hereinafter, several embodiments of the present invention will be described with reference to the drawings. In the following description, the common reference signs are used when the same kind of elements are not distinguished, and the reference signs may be used when the same kind of elements are distinguished.

[ first embodiment ]

Fig. 1 is a schematic view of the inside of a car of the first embodiment.

A car operating panel 10 is provided on the right side of the car 5 when viewed from the front inside the car of the elevator. The car operating panel 10 may be provided on the left side of the door 5 instead of or in addition to the right side of the door 5. The arrangement described below, that is, the non-contact sensor is arranged on the side opposite to the side of the door 5 (the side farther from the door 5) than the destination floor button, and the braille portion is arranged on the side of the door 5 than the destination floor button, is maintained regardless of whether the car operating panel is provided on the left or right of the door 5.

Fig. 2 is a schematic view of the car operating wheel 10.

The car control panel 10 includes a monitor 30, a plurality of destination floor buttons 20 arranged in the vertical direction and each having a contact type, a plurality of proximity sensors 40 arranged in the vertical direction and corresponding to the plurality of destination floor buttons 20, and a plurality of braille portions 25 arranged in the vertical direction and corresponding to the plurality of destination floor buttons 20. That is, for each floor that can be designated as a destination floor, there are the destination floor button 20 and the contactless sensor 40 and the braille portion 25 (e.g., braille plate). In the present embodiment, since five floors capable of being designated as destination floors are provided, the present embodiment includes destination floor buttons 20a to 20e, proximity sensors 40a to 40e, and braille portions 25a to 25 e. The car operating panel 10 includes a contact-type door closing button 51 that is pressed for operating to close the door 5, and a contact-type door opening button 52 that is pressed for operating to open the door 5. The door closing button 51 and the door opening button 52 may be provided with a non-contact sensor on the car control panel 10 instead of or in addition to the above buttons, but a contact button may be used at least for the door opening button 52, and a non-contact sensor may not be provided instead of or in addition to the above buttons. In the present specification, "contact" of "contact" may be contact in a narrow sense, but may be contact in a broad sense including pressing.

Each of the proximity sensors 40 has a function as a destination floor button 20 corresponding to the proximity sensor 40, registers a floor corresponding to the proximity sensor 40 as a destination floor when triggered, and is disposed on the side (right side) opposite to the door 5 side with respect to the destination floor button 20 corresponding to the proximity sensor 40. The noncontact sensor 40 may be a proximity sensor of an infrared ray, an induction type, an electrostatic capacitance type, an ultrasonic type, a magnetic type, or the like. For example, if a sensor having narrow directivity is used as the proximity sensor 40, it can be expected to avoid the necessity of making the interval between the sensors 40 large. In the present embodiment, the proximity sensor 40 irradiates light and detects reflected light from an object that receives the light, thereby detecting the object.

On the other hand, each braille portion 25 is disposed on the door 5 side of the destination floor buttons 20 corresponding to the braille portion 25. The braille portion 25 has braille indicating at least a destination floor.

In the present embodiment, the non-contact sensor 40 is used for a designated destination floor for one of purposes of coping with infectious diseases and keeping hygiene, but the non-contact sensor 40 is provided in addition to the destination floor button 20. Thus, even if the detection accuracy of any one of the proximity sensors 40 is degraded (or any one of the proximity sensors 40 fails), the destination floor can be specified using the destination floor button 20.

Further, for each floor that can be designated as a destination floor, the destination floor button 20 is disposed between the braille portion 25 and the proximity sensor 40 along the horizontal direction (left-right direction). Therefore, when the visually impaired person gets on the car 5 and extends his or her hand to the car operating panel 10 to specify the destination floor, the finger touches the braille portion 25, and the destination floor indicated by the braille portion 25 can be known. Further, if the visually impaired moves the hand from the position of the braille portion 25 to the right in the horizontal direction while touching the surface of the car operating panel 10, the visually impaired can expect the hand to reach a button capable of designating a destination floor. In the present embodiment, the destination floor button 20 is disposed on the door 5 side (left side) of the non-contact sensor 40, and the destination floor button 20 has a height higher than the surface of the car operating panel 10 because it is a contact type button. Therefore, the button touched by the visually impaired person after touching the braille portion 25 is highly likely to be the destination floor button 20 that the visually impaired person can touch and recognize. Thus, even if the car control panel 10 includes the proximity sensor 40 for specifying the destination floor, it is possible to assist the visually impaired person in accurately specifying the desired destination floor.

In the case where there are many floors that can be designated as destination floors, the rows of destination floor buttons along the vertical direction are generally two or more rows arranged in the left-right direction, and in the present embodiment, the car operating panel 10 is extended in the vertical direction, and the rows of the braille portions 25, the rows of the destination floor buttons 20, and the rows of the proximity sensors 40 are maintained in one row. Thus, even in the case where the elevator is installed in a tall building or where many floors can be designated as destination floors in one car for other reasons, it is expected that the improvement in the operability described above will be maintained.

For each destination floor button 20, a convex portion is provided between the destination floor button 20 and the proximity sensor 40 corresponding to the destination floor button 20. The convex portion is a member having a height higher than that of the car operating panel 10. The visually impaired person touches the convex portion when the hand is further moved in the right direction without touching the destination floor button 20 or while passing over the destination floor button 20. The convex portion indicates that the noncontact sensor 40 is present at a farther position (a farther side from the door 5) than the convex portion. Therefore, the convex portion prompts the visually impaired person who touches the convex portion to stop moving the hand farther than the convex portion, thereby avoiding the non-contact sensor 40 corresponding to the wrong floor from detecting the hand or finger.

The convex portion may be provided for each destination floor button 20 (for example, a plurality of convex portions spaced apart from each other in the vertical direction may be provided), but in the present embodiment, the convex portion is a partition wall 110 that is an example of a member that is located between the row of destination floor buttons 20 and the row of proximity sensors 40 and is continuous in the vertical direction. Thus, even if the finger of the visually impaired person moves rightward beyond the position of the destination floor button 20 after touching the braille portion 25 (for example, even if the finger passes through the gap between the destination floor buttons 20 or the like so that the finger moves rightward without touching the destination floor button 20), the finger reaches the partition wall 110 because the partition wall 110 is continuous in the up-down direction (does not have a gap in the up-down direction). Therefore, it is avoided that the reliability of detecting the hand or finger by the proximity sensor 40 corresponding to the wrong floor is improved.

Fig. 3 is a sectional view a-a of fig. 2. In the explanation of fig. 3, it is assumed that the destination floor of the visually impaired person is 5 floors.

The braille portion 25e, the destination floor button 20e, the partition wall 110, and the noncontact sensor 40e are arranged in the horizontal direction from the left side (door side) to the right side (opposite side to the door side).

As shown in the drawing, in the case where the non-contact sensor 40e is on the same plane as the surface of the car operating panel 10, if there is no destination floor button 20e (if the non-contact sensor 40e is employed instead of the destination floor button 20e as a button for specifying the destination floor (5 floors)), it is difficult for the visually impaired person to accurately estimate the position of the non-contact sensor 40e even if the braille portion 25e is touched, but in the present embodiment, because there is a destination floor button 20e between the braille portion 25e and the non-contact sensor 40e, the visually impaired person can be expected to accurately specify 5 floors as the destination floor.

Even if the position of the finger beyond destination floor button 20e is moved to the right side because the finger of the visually impaired person does not touch destination floor button 20e, the finger collides with partition wall 110, and therefore, it is possible to avoid that the finger passes over partition wall 110 and non-contact sensor 40 corresponding to a floor other than floor 5 detects a hand or finger. The height of the partition wall 110 (an example of the convex portion) may be any height. For example, the partition wall 110 is higher than the destination floor buttons 20.

Fig. 4 is a schematic configuration diagram of a system including an operating device having the car operating panel 10.

The operating device 300 has at least a car operating panel 10. The operating device 300 may further have a non-contact sensor controller 60, a destination floor display controller 70, a monitor controller 80 connected to the monitor 30 and controlling the display on the monitor 30, and an in-car operating control device 90. An elevator control device 100 that controls the raising and lowering of the car 5 is connected to the manipulator 300. The elevator may include the car 5 itself, an elevator mechanism of the car 5, and the like, in addition to the operating device 300 and the elevator control device 100.

The non-contact sensor controller 60 is electrically connected to each non-contact sensor 40. For example, when the non-contact sensor 40 detects an object, the signal from each non-contact sensor 40 is equal to or higher than a predetermined level. The non-contact sensor controller 60 identifies the non-contact sensor 40 whose signal is equal to or higher than a predetermined level, and outputs the floor number corresponding to the non-contact sensor 40 to the in-car steering control device 90.

The destination floor display control 70 is electrically connected to the destination floor buttons 20. When the destination floor button 20 is touched (e.g., pressed), the destination floor indication controller 70 lights the destination floor button 20 and outputs the floor number of the destination floor button 20 to the in-car operation control device 90.

The monitor controller 80 is electrically connected to the monitor 30, and displays information (for example, a destination floor, an advertisement, and the like) from the in-car operation control device 90 on the monitor 30.

When a floor number is input (that is, when a destination floor is designated), the in-car operation control device 90 outputs the floor number to the monitor controller 80 and the elevator control device 100. The elevator control device 100 registers the inputted floor number as a destination floor, and controls the raising and lowering (operation) of the car.

When the input source of the floor number is the non-contact sensor controller 60, the in-car operation control device 90 outputs the floor number to the destination floor indication controller 70. The destination floor indication controller 70 receives an input of a floor number from the in-car operation control device 90, and lights the destination floor button 20 corresponding to the floor number when the destination floor button 20 is not lighted.

[ second embodiment ]

A second embodiment will be explained. In this case, differences from the first embodiment will be mainly described, and common features to the first embodiment will be omitted or simplified.

In the second embodiment, a predetermined event, which is at least one of a touch of the partition wall 110 by a hand or a finger and a crossing of the partition wall 110 by the hand or the finger to the opposite side of the door 5 side, is detected, and when the predetermined event is detected, at least a part of the proximity sensors 40 is temporarily deactivated.

For example, the manipulator 300A further has a convex portion checker 130. The convex portion checker 130 may detect the above-described prescribed event by employing at least one of the following.

The convex portion checker 130 is electrically connected to the partition wall 110, and detects that a hand or a finger touches the partition wall 110 from the level of an electrical signal when the hand or the finger touches the partition wall 110. For example, a signal line extending from a plurality of positions of the partition wall 110 in the vertical direction may be connected to each of the protrusion inspectors 130, and the protrusion inspectors 130 may be able to detect which position of the plurality of positions of the partition wall 110 in the vertical direction is touched by a hand or a finger.

A detection device (not shown) for detecting that an object such as a hand or a finger has passed over (crossed over) to the right at a position higher than the partition wall 110 is provided, and the convex portion checker 130 is electrically connected or communicably connected to the detection device. The detection device may be a camera (for example, a camera provided in the car), or may be a plurality of sensors (each of which may be a type that emits light and detects an object from reflected light of the object) that are provided between the row of the destination floor buttons 20 and the row of the proximity sensors 40 at a plurality of positions arranged in the vertical direction along the partition wall 110. Any of these apparatuses is used as the detection apparatus, and detects that an object such as a hand or a finger has passed right over the position higher than partition wall 110, and convex part checker 130 can detect that the object has passed right over the position higher than partition wall 110 and the position over which the object has passed, based on an input from the apparatus.

When the predetermined event and the position thereof are detected as described above, the convex portion checker 130 notifies the non-contact sensor controller 60A of the detection of the predetermined event and the detected position via the in-car steering control device 90A. When receiving the detection of the predetermined event, the proximity sensor controller 60A temporarily deactivates at least some of the proximity sensors 40 among the plurality of proximity sensors 40. The "temporary" may be a fixed time or may be a time until a specific event different from the above-described predetermined event is detected. The "invalid" may be a state in which the noncontact sensor 40 cannot detect an object, or may be a state in which the detection is ignored even if the noncontact sensor 40 detects an object.

According to the present embodiment, the detection of a predetermined event is regarded as a sign that a hand or a finger is detected by the wrong proximity sensor 40, and in such a case, the proximity sensor 40 is deactivated, so that it is possible to avoid registration of a wrong destination floor. Further, since the invalid proximity sensor 40 is a part of the proximity sensor 40, the passenger other than the visually impaired can continue to use the proximity sensor 40.

In addition, "at least a part of the proximity sensors 40" may be proximity sensors located within a predetermined range from the position of the above-described predetermined event. This makes it possible to maintain the effectiveness of the proximity sensor 40 located at a position distant from the position of the predetermined event, in other words, the proximity sensor 40 having a low possibility of the hand or finger being erroneously extended.

The above description has been made of several embodiments, but these are examples for illustrating the present invention, and the scope of the present invention is not limited to these embodiments. The present invention can be implemented in various other embodiments.
