    FIELD OF INVENTION
    [01] The present invention concerns a switch, without contact used in elevators or automatic doors in general. BRIEF DESCRIPTION OF THE INVENTION
    [02] Mechanical push-button switches, touch pad, beam switches that use the optical sensor, and the like are generally used as up, down, and pavement selection buttons.
    [03] The state of the art describes touch switches in which the human finger comes into direct contact with the surface of a button, such as a touch pad (figure 1A) or pressure button (figure 1B), including, in this case Of the optical sensor-type switches, shown in Figure 1C, since the human finger needs to press deep enough for the sensor to detect the finger, there is a high possibility that the finger will come into contact with the inside of the switch.
    [04] The contact switch can be unsanitary because there is a high risk that a human being could be infected with bacteria or viruses through contact. Furthermore, when people with disabilities, including those who are blind or visually impaired, unconsciously press the switch with their fingers while looking for it, it can be turned on; therefore, the contact switch may be unsuitable for use by people with disabilities.
    [05] In addition, in modern elevators, switches with raised letters must be installed separately, in a significantly lower position, so that the visually or physically impaired can use them separately from ordinary switches that are used by people without disabilities. The reason for installing switches for people with disabilities at large intervals from common switches is to reduce the risk of a disabled person using the elevator improperly by touching common switches by mistake. For this, there is a need for wires for two types of switches: switches for people with disabilities and common switches.
    [06] Switches that do not require contact are described in several patent documents.
    [07] EP1995610 describes an arrangement that includes light transmitters to transmit light to a monitored area, having photoreceptors with receiving segments and photodiode array to generate signals using light. The segments are arranged parallel to each other across the direction, and the transmitters and receivers are arranged across the direction. The evaluation unit has a device to determine the direction and/or speed of movement of the signals.
    [08] The document US6161655 describes an elevator call button that transmits infrared radiation to the space adjacent to an elevator, and a call request is recognized by the infrared radiation reflected from a potential passenger to an infrared receiver, not requiring use of a finger or similar sized object to make a call.
    [09] Document JP2005255260 describes an elevator button composed of an input piece of the floor number stop using a non-contact sensor, such that the non-contact sensor switch is connected to the inner wall of a large hole enough to allow the insertion of a finger without contacting the inner wall.
    [010] The document US4716992 describes an operation panel of an elevator that has a plurality of indication marks described therein; a plurality of first light-emitting elements for emitting light signals which pass along a surface of the indicator panel through the indication marks; and a plurality of light receiving elements for receiving the light signals from the first light emitting elements, whereby when at least one of the light signals emitted by the first light emitting elements passes through one of the indicator marks on the indicator panel it is selectively interrupted , the light receiving elements detect a selective interruption of at least one light signal and send to an appropriate control system an operating command signal corresponding to the specific indication mark.
    [011] The document KR20100083938 describes a non-contact interface equipment that replaces the push button of the elevator call button, featuring a non-contact sensor illumination emission area and the photodiode that detect motion. The sensor signal processor processes the passenger motion detection signal that crosses the light emitting area of the non-contact sensor/photodiode and the processing unit moves the elevator with the control signal from the processor.
    [012] Still, the state of the art describes bifunctional buttons, that is, that can be activated by touch or not, such as document CN2619415 which describes a bifunctional elevator button switch comprising a button switch panel, a contact button, an infrared launch tube and an infrared receiver tube. A pair or a plurality of pairs of infrared launch tubes and infrared receiving tubes are arranged on the periphery of the concave portion in front of the pushbutton switch and are connected in parallel.
    [013] However, the solutions described in the prior art do not prevent the accidental activation of the non-contact switch and/or the contact switch, even more when the user is visually impaired or a child. The proximity of the switches and the sensitivity of the sensing elements can trigger an elevator or door in a more abrupt movement of the user's finger, or due to touch for the identification of the interface.
    [014] Thus, the present invention patent describes a bifunctional interface, where buttons that require the contact of the user's finger are provided and assigned to non-contact switches in the form of a pair of sensor blocks arranged spaced apart by a space 3 to 6 centimeters (equivalent to two or three fingers), with the surface of the sensor blocks having a plurality of sensors for detecting the direction, length and speed of displacement of the human finger in space. Thus, the sensor block, being a projecting structure, constitutes an obstacle that prevents, inadvertently, a disabled user or a child from activating the contact switch or accessing the area of a contactless switch disposed adjacently, providing a structure that restricts the user's finger movement while conducting this movement, in an intuitive way, to ensure that in fact the signal obtained by the sensor is surely an action of the user for the proper purpose, without the risk of triggering promoted by mistake or by proximity TECHNICAL PROBLEM
    [015] It is, therefore, an objective of the present invention to simplify installation and wiring in addition to significantly reducing the installation cost when installing switches for people with and without disabilities in a panel.
    [016] It is still the aim of the present invention to provide a hygienic switch without risk of infection by allowing people without disabilities to use the switch in non-contact mode.
    [017] It is a further objective of the present invention to provide a safe switch that is not improperly used by wrong contact which can occur while the visually impaired or any other disabled person is looking for it. TECHNICAL SOLUTION
    [018] To achieve the objectives of the present invention, a switch installed next to the elevator door in the entrance hall of the building to select the up movement, the down movement of the elevator or the destination floor, or installed next to an automatic door that opens and closes automatically, to open the same.
    [019] The non-contact switch comprises a pair of sets of long sensor blocks arranged to face each other, with a space (F) between them 3 to 6 centimeters wide (equivalent to two or three fingers) , and a plurality of sensors (S) installed in line on the surface of the sensor blocks facing each other, whereby, when the finger moves in space (12), the sensors (S) detect the direction, the length and the speed of the finger (F) that moves. Therefore, the elevator can go up, or the destination floor can be selected, or the automatic door can be opened using the detected information in the manner described above.
    [020] The buttons (B), including the push button or button with optical sensor, which activate the elevator or the automatic door when pressed by the finger, can be arranged around, that is, on the side, above or below of the sets of sensor blocks (10).
    [021] In this case, a plurality of buttons (B) is provided and the sets of sensor blocks (10) are arranged next to the respective buttons (B), one by one; furthermore, each set of sensor blocks (10) is not arranged parallel to the set of sensor blocks facing the set of sensor blocks (10), but forms a V-shaped angle. ADVANTAGEOUS EFFECTS
    [022] According to the non-contact selector switch of the present invention, configured as described above, switches for people with and without disabilities can be incorporated into a panel, significantly reducing its installation cost, with the switch being operated without need to touch it and so it is hygienic; the possibility of malfunction that can occur when people with disabilities look for the switch can be significantly reduced.

    [033] Figure 11A shows a state in which the non-contact switch is activated and is arranged next to the elevator buttons, and figure 11B shows a state in which the up button is pressed by the finger. DETAILED DESCRIPTION OF THE INVENTION
    [034] As shown in figure 2, the non-contact switch is installed on the side of the elevator to select the up or down movement of the elevator, but it can be used to select the destination floor. Therefore, the switch can be installed next to an automatic door that opens and closes automatically, which will be described in detail below.
    [035] The non-contact switch, according to the present invention, comprises a button (B), a set of sensor blocks (10) and a sensor (S).
    [036] The button (B) is a button used to operate the elevator, that is, select the ascent or the destination floor, pressing the button by hand, and it can be a push button (BP) or button with sensor optical (SO) described in the prior art. The set of sensor blocks (10) is installed beside or above the button (B), including a pair of blocks arranged to face each other, with a space (12) 3 to 6 centimeters wide ( the equivalent of two or three human fingers). The sensor (S) is installed in-line on the surface of the sensor blocks (10), said sensor (S) selected from an optical sensor or a photoelectric sensor.
    [037] As shown in Figures 3A and 3B, the finger moves in the space (12) formed between the set of sensor blocks (10), and only when the finger is bent with respect to the space (12), in the form of a broken line, the lower button (B) is activated and, conversely, when the finger moves up, the upper button (B) is activated. Therefore, as shown in figure 3B, button (B) can be pressed directly with your finger. The switch works with only one of the two methods.
    [038] In the case of the switch, since the set of sensor blocks (10) protrude, there is no risk that the visually impaired person can cause malfunction through a wrong contact. The drive (up or down movement) of the elevator can be selected taking into account the distance, speed and direction in which the finger moves in space (12), and since the method of operation is obvious to the experts in the field, the more detailed description will be omitted. For example, only when the finger moves 2/3 or more of the total length of the space (12), it is possible to configure the elevator to trigger or go up or down depending on the direction of the finger. The method of operation will be described in detail below.
    [039] Figures 4A, 4B and 4C show an example in which the set of sensor blocks (10) is arranged horizontally, being composed of three sensor blocks, to configure a total of two sets, with the same operation as in the example of Figures 3A and 3B. For example, as shown in figure 4B, the elevator is activated when the finger moves or the button (B) is pressed in the space of the sets of sensor blocks (10).
    [040] Figure 5 shows a button switch installed in the elevator car, and not in the entrance hall, with several buttons being provided, such as the button that selects the floor (floor button) and the buttons for opening and closing the elevator. In this case, the set of sensor blocks (10) can be assigned to each button. That is, the sets of sensor blocks (10) are arranged next to the respective buttons (B), one by one, and when the finger moves on each sensor block (10), according to a pre-established rule , you can choose the desired floor or open or close the elevator door. That is, as shown in the enlarged diagram, it is possible to select a floor by moving your finger on the set of sensor blocks (10) corresponding to the first floor.
    [041] Therefore, in this configuration, it is preferable that each of the multiple sets of sensor blocks (10) is not arranged parallel or in-line with respect to the set of sensor blocks that is opposite each set of sensor blocks.
    [042] For example, as shown in Figure 5, both sets of sensor blocks (10) corresponding to the third floor and the sixth floor are not arranged in line, but are arranged to form an angle. This is because, when both sets of sensor blocks (10) are arranged in a row, visually impaired people or children may mistakenly trigger both sets of third and sixth floor sensor blocks at the same time with their finger. However, when the sets of sensor blocks (10), facing each other, form a predetermined angle, being arranged in a V-shape, there is no risk of the two floors being selected at the same time by mistake, as described above.
    [043] Figure 6 is a perspective view demonstrating an example where the present invention is applied to a common automatic door switch. In this configuration, the set of sensor blocks (10) is installed above the button (B) installed next to the common automatic door. The finger moves in the middle of the space of the set of sensor blocks (10) to trigger the automatic door in a similar way to the modality shown in figure 5. That is, when the finger moves, as shown by the broken line, the door automatic opens even though button (B) is not pressed.
    [044] Figure 7 shows the block diagram showing the operation of the set of sensor blocks (10) when the non-contact switch is configured by the photoelectric sensor, with the right sensor block consisting of a plurality of light-emitting units (nine) and the left sensor block also consists of the same number of light receiving units. The light receiving unit is connected to a sensor switch controller of the light receiving unit, and both the up and down switches are connected to said controller. The finger (F) is marked with an oval between the light receiving unit and the light emitting unit, while the finger (F) moves up and down in the direction of an arrow, the light received by the unit light receiving unit from the light emitting unit is blocked
    [045] Figures 8 and 9 are flowcharts of an operational state of the set of sensor blocks (10), and figure 9 shows the flowchart of an upper floor and a lower floor that only need a switch, and the figure 8 is the flowchart of a floor with both up and down switches.
    [046] In the case of floors other than the upper and lower floors (as shown in figure 8), when both the up and down switches are in the off position, it is decided whether the sequential detection occurs unidirectionally in the sensors (S) enter, in this case, nine sensors, by the movement of the finger. In the present mode, S is set to five. When sequential detection occurs, it is decided whether the time difference between the first and the last sensor, detected in the next step, is within R. In the present mode, R is set to 0.5 seconds.
    [047] When detection takes place within the set time, in the next step it is decided whether the sensor detection order is ascending order. When the detection order is descending order, the down switch is in the on position, and when the detection order is not ascending, the up switch is in the on position. In general, when the detection order is ascending, the finger moves down, otherwise the finger moves up.
    [048] Therefore, in the case of the upper floor and the lower floor, only the up switch or the down switch, respectively, is provided. In other words, in this case, as shown in figure 9, it is not necessary to decide whether the sensor detection order is ascending, and when the detection occurs within a pre-established period of time, it is assumed that the switch is activated.
    [048] As described above, when both the up and down switches or one of the two switches and the non-contact switch are provided together, a contactless switch actuation relationship is described, but even when only the non-contact switch is provided without the rise switch, it is possible to apply the drive ratio. Furthermore, the non-contact switch according to the present invention can be applied even to a common on/off switch and added to the elevator.
    [049] Figure 10 is a schematic view demonstrating the relationship between an elevator common button switch and a non-contact switch, according to the present invention, when the common button switch and the non-contact switch are used simultaneously.
    [050] In this case, the common pushbutton switch and the non-contact switch, according to the present invention, are arranged parallel to each other. In other words, the elevator can be activated by any of the switches.
    [051] Figure 11 is a perspective view demonstrating another example of the non-contact switch, according to the present invention, and illustrates a state in which the non-contact switch is arranged not between the rise buttons, but beside the up buttons, the non-contact switch works when actuated by the finger. Figure 11A shows a state where the non-contact switch is actuated, and figure 11B shows a state where the raise button is pressed directly. Therefore, the non-contact switch according to the present invention can be used in various combinations with the existing raise button.
    [052] The non-contact switch described above is just an example, and it can be included in the scope of the invention even when any of the light receiving and emitting units consists of a plurality of sensors. In addition, the sequential detection number and detection time can also be adjusted as needed.
