Description

[Technical field]

[0001] The present disclosure relates to a hall push button protection device used to protect a hall push button of an elevator. [Background technology]

[0002] Patent Document 1 discloses technology related to an elevator inspection work display system. In this technology, when a maintenance worker is performing an inspection work, call registration is prohibited to prohibit elevator users from entering the elevator, and a message is displayed on the hall position indicator indicating that an inspection work is being performed.

[0003] [Patent Document 1] JP 2005-67838 A Summary of the Invention [Problem to be solved by the invention]

[0004] The system of Patent Document 1 is expected to be effective in letting users at the hall know that the elevator is unavailable because it is undergoing inspection or out of order. However, some hall users may overlook the text display. In this case, there is a risk that they may press the inoperable hall button harder than necessary or press it repeatedly, which may result in damage to the hall button.

[0005] The present disclosure has been made to solve the problems described above, and aims to provide an elevator hall push button protection device that can reliably prevent users from operating the hall push button in situations where elevator use is restricted. [Means for solving the problem]

[0006] The elevator landing push button protection device of the present disclosure comprises a rotating body having a landing push button surface on which the elevator landing push button is located and a display surface on which a notation indicating that elevator use is restricted is printed, an actuator that rotates the rotating body to alternatively switch between a first state in which the landing push button surface is exposed to the landing and a second state in which the display surface is exposed to the landing, and a control device that drives the actuator to set the rotating body to the first state in a normal state in which the elevator can be used, and to the second state in a restricted state in which elevator use is restricted. Effect of the Invention

[0007] According to the elevator hall push button protection device of the present disclosure, When the elevator is in a restricted state where use of the elevator is restricted, the rotor is rotated to switch from a state in which the hall push button surface is exposed to the hall to a state in which the display surface is exposed to the hall. This makes it possible to reliably prevent users from operating the hall push button when the elevator is in a restricted state where use of the elevator is restricted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In addition, elements common to the various drawings are given the same reference numerals, and duplicated explanations will be omitted.

[0010] Embodiment 1. Configuration of the elevator according to the embodiment FIG. 1 is a configuration diagram of an elevator 1 according to an embodiment of the present disclosure. The elevator 1 is installed in a building with multiple floors. Each floor is provided with a landing 2. Each landing 2 is provided with a landing door 4 and an indicator 6. The indicator 6 is provided with a display unit 8 that indicates the current car position, and a landing push button 12 for calling the elevator 1. The landing push button protection device of this embodiment is a device that protects the landing push button 12 by storing the landing push button 12 in the indicator 6 during a breakdown or inspection of the elevator 1. The configuration of the landing push button protection device will be described in detail below.

[0011] 2. Configuration of the hall push button protection device 10 Fig. 2 is a schematic diagram for explaining the configuration of the hall push button protection device. In addition, (A) in Fig. 2 is a front view of a part of the indicator 6 in which the hall push button protection device is arranged, as seen from the hall, (B) in Fig. 2 is a plan view showing the inside of the indicator 6 in which the hall push button protection device is arranged, and (C) in Fig. 2 is a side view showing the inside of the indicator 6 in which the hall push button protection device is arranged, with a perspective.

[0012] The main components of the landing push button protection device 10 include a rotating body 20 arranged inside each of the indicators 6 of each floor, an actuator 22 that rotates and moves each of the rotating bodies 20, and a control device 40 that collectively controls the operation of each actuator 22.

[0013] FIG. 3 is a perspective view showing the appearance of the rotating body and the actuator. The configuration of the hall push button protection device 10 will be described below with reference to FIG. 3. The rotating body 20 is a columnar structure configured to be rotatable around a rotating shaft 24. The rotating body 20 includes a hall push button surface 201 on which the hall push button 12 is arranged, a malfunction indication surface 202 on which the characters "out of order" are printed adjacent to one side of the hall push button surface 201, and an inspection indication surface 203 on which the characters "in inspection" are printed adjacent to the other side of the hall push button surface 201. The hall push button surface 201 is configured as a flat surface, and the malfunction indication surface 202 and the inspection indication surface 203 are configured as arc surfaces by arcs centered on the axial center of the rotating shaft 24.

[0014] The hall push button 12 includes an up call button 14 for calling an elevator in the up direction, and a down call button 16 for calling an elevator in the down direction. The push button wiring 18 of the hall push button 12 is pulled out toward the back side of the indicator 6 so as not to impede the rotational movement of the rotor 20, and is connected to an elevator control panel (not shown).

[0015] FIG. 4 is a diagram showing an example of a rotating body displayed on an indicator. In the reference position, the rotating body 20 exposes the landing push button surface 201 to the landing 2 through the rectangular opening 6a of the indicator 6. This state is realized in a normal state in which the elevator 1 can be used, and is hereinafter referred to as the "first state". In contrast, the rotating body 20 rotates clockwise or counterclockwise from the reference position to expose the inspection indication surface 203 or the malfunction indication surface 202 to the landing 2 through the rectangular opening 6a. This state is realized in a restricted state in which the use of the elevator 1 is restricted, and is hereinafter referred to as the "second state". In the second state, the state in which the malfunction indication surface 202 is exposed to the landing 2 through the rectangular opening 6a is also called the "third state", and the state in which the inspection indication surface 203 is exposed to the landing 2 through the rectangular opening 6a is also called the "fourth state".

[0016] The actuator 22, which is, for example, an electric motor, is for selectively switching between a first state and a second state by rotationally moving a rotation shaft 24 of the rotor 20. An actuator wiring 26 of the actuator 22 is drawn toward the back side of the indicator 6 so as not to impede the rotational movement of the rotor 20, and is connected to the control device 40.

[0017] 3. Functional configuration of the hall push button protection device 10 FIG. 5 is a block diagram showing an example of the functional configuration of the landing push button protection device. The landing push button protection device 10 includes, as main components related to the functions, a control device 40, an actuator 22 arranged in the indicator 6 of each floor, and an alarm device 52 installed on each floor. The control device 40 has a function of a processing device as a computer. Typically, the control device 40 includes at least one processor 42 and at least one memory 44 coupled to the processor 42. The memory 44 stores at least one program 441 executable by the processor 42 and various data 442 related thereto. The processor 42 executes the program 441, thereby realizing various processes by the processor 42.

[0018] 6 is a functional block diagram showing functions realized by the processor 42 of the control device 40 executing the program 441. As shown in FIG. 6, the processor 42 includes an acquisition unit 421, an in-failure display processing unit 422, an in-inspection display processing unit 423, a recovery processing unit 424, and an alarm processing unit 425.

[0019] The acquisition unit 421 is a functional block for receiving from the elevator 1 a fault signal, an inspection signal, or a switching signal that is issued when the use of the elevator 1 is restricted. This process is hereinafter referred to as the "acquisition process." The fault signal is a signal transmitted from the control panel when a fault occurs while the normal power supplied to the elevator 1 is ON. The inspection signal is a signal transmitted from the control panel when an inspection switch provided in the car operation panel is turned ON during inspection of the elevator 1. The switching signal is a signal transmitted when the normal power supplied to the elevator 1 is turned OFF due to a fault or the like, and the power supplied to the elevator 1 is switched from the normal power to the emergency power by a switching device.

[0020] When the acquisition unit 421 receives a fault signal or a switching signal, the fault display processing unit 422 generates an operation command for rotating the rotating body 20 counterclockwise from the reference position to display the fault display surface 202 in the rectangular opening 6a of the indicator 6, and transmits the operation command to the actuator 22. This process will be referred to as "fault display process" hereinafter.

[0021] When the acquisition unit 421 receives an inspection signal, the inspection-in-progress display processing unit 423 generates an operation command for rotating the rotating body 20 clockwise from the reference position to display the inspection-in-progress display surface 203 in the rectangular opening 6a of the indicator 6, and transmits the operation command to the actuator 22. This process will be referred to as "inspection-in-progress display process" hereinafter.

[0022] When the inspection switch is returned from ON to OFF, when the fault signal is reset, or when the power supplied to the elevator 1 is returned from the emergency power supply to the normal power supply, the return processing unit 424 generates an operation command for returning the rotor 20 to the reference position and displaying the hall push button face 201 in the rectangular opening 6a of the indicator 6, and transmits the operation command to the actuator 22. This process will be referred to as "return processing" hereinafter.

[0023] Furthermore, the alarm issuing processing unit 425 transmits an operation command to the alarm issuing device 52 to issue a warning to users present at the hall 2 while the actuator 22 is being driven. This processing is hereinafter referred to as "alarm issuing processing." The alarm issuing device 52 is, for example, a hall unusable buzzer provided in the elevator 1, and issues a buzzer sound as a warning sound in the alarm issuing processing. Alternatively, the alarm issuing device 52 is, for example, a speaker installed in each hall 2, and issues a warning announcement to call attention in the alarm issuing processing.

[0024] 4. Specific processing executed in the hall push button protection device 10 Hereinafter, with reference to a flowchart, an operation of the control device 40 to protect each of the hall push buttons 12 on each floor during inspection or during a breakdown of the elevator 1 will be described. Fig. 7 is a flowchart of a routine executed by the control device 40. The routine shown in Fig. 7 is repeatedly executed by the processor 42 of the control device 40 at a predetermined control period.

[0025] The process of step S100 corresponds to an acquisition process executed by acquisition unit 421. Specifically, in step S100, it is determined whether or not a failure signal or a switching signal has been received. If the determination is found to be true, the process proceeds to step S102, and if the determination is not found to be true, the process skips step S102 and proceeds to step S104.

[0026] Step S102 corresponds to the out-of-order display process executed by the out-of-order display processing unit 422. Specifically, in step S102, an operation command is transmitted to the actuator 22 to rotate the rotor 20 counterclockwise from the reference position and display the out-of-order display surface 202 in the rectangular opening 6a of the indicator 6. The actuator 22 operates in accordance with the received operation command, whereby the landing push buttons 12 on each floor are stored inside the indicator 6, and the "out-of-order" notation printed on the out-of-order display surface 202 is displayed on the indicator 6.

[0027] The process of step S104 corresponds to an acquisition process executed by the acquisition unit 421. Specifically, in step S104, it is determined whether or not an inspection signal has been received. If the determination is found to be true, the process proceeds to step S106, and if the determination is not found to be true, the process skips step S106 and proceeds to step S108.

[0028] Step S106 corresponds to an inspection-in-progress display process executed by the inspection-in-progress display processing unit 423. Specifically, in step S106, an operation command is transmitted to the actuator 22 to rotate the rotating body 20 clockwise from the reference position and display the inspection-in-progress display surface 203 in the rectangular opening 6a of the indicator 6. The actuator 22 operates in accordance with the received operation command, whereby the landing push buttons 12 on each floor are stored inside the indicator 6, and the "inspection-in-progress" notation printed on the inspection-in-progress display surface 203 is displayed on the indicator 6.

[0029] The processes of steps S108 and S110 correspond to the alarm process executed by the alarm processing unit 425. Specifically, in step S108, it is determined whether the actuator 22 is being driven. If the determination is found to be true, the process proceeds to step S110, and if the determination is not found to be true, the process proceeds to step S112.

[0030] In step S110, an alarm is issued from each alarm issuing device 52 on each floor. After the process of step S110 is performed, the process returns to step S108 again. As a result, the alarm issuing device 52 continues to issue an alarm while the actuator 22 is being driven.

[0031] Steps S112 and S114 correspond to the recovery process executed in the recovery processing unit 424. Specifically, in step S112, it is determined whether the elevator 1 has recovered from inspection or from a malfunction. As a result, if the determination is not found to be true, this routine is terminated, and if the determination is found to be true, the process proceeds to step S114. In step S114, an operation command is transmitted to the actuator 22 to return the rotating body 20 to the reference position and display the hall push button face 201 on the indicator 6. The actuator 22 operates in accordance with the received operation command, causing the rotating body 20 to rotate and move, and the hall push button 12 stored inside the indicator 6 is displayed on the indicator 6 again.

[0032] According to the operation of the hall push button protection device 10 as described above, when the elevator 1 is inspected or broken, the hall push button 12 is stored inside the indicator 6. This reliably prevents the hall push button 12 from being operated by a user, and therefore reliably prevents damage to the hall push button 12.

[0033] According to the operation of the hall push button protection device 10, when the elevator 1 is being inspected or broken, the indicator 6 can display "under inspection" or "out of order." This allows users at the hall 2 to be aware of the situation in which the elevator 1 cannot be used.

[0034] In addition, since the indications "under inspection" or "out of order" on the rotating body 20 are printed, no power source is required as in the case of using an LED or the like. Therefore, even if the power supply is temporarily cut off due to inspection or an outage, it is possible to maintain the indications "under inspection" or "out of order."

[0035] Since the out-of-order indication surface 202 and the under-inspection indication surface 203 of the rotating body 20 are configured with arc surfaces, gaps are unlikely to occur between the rectangular opening 6a and the out-of-order indication surface 202 and the under-inspection indication surface 203 during rotational movement. This makes it possible to prevent the fingers, etc., of users at the boarding area 2 from being pinched.

[0036] When the elevator 1 is being inspected or broken down, the rotational movement of the rotating bodies 20 on each floor is performed simultaneously, so that users on all floors can be informed that the elevator is "inspecting" or "broken down" at the same time.

[0037] 6. Variations The hall push button protection device 10 of this embodiment may be modified as follows.

[0038] 6-1.Control device 40 Fig. 8 is a diagram showing a modified example of the hardware resources of the control device. In the example shown in Fig. 8, the control device 40 includes a processing circuit 48 including, for example, a processor 42, a memory 44, and dedicated hardware 46. Fig. 8 shows an example in which a part of the functions of the control device 40 is realized by the dedicated hardware 46. All of the functions of the control device 40 may be realized by the dedicated hardware 46. As the dedicated hardware 46, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof can be adopted.

Furthermore, the characters displayed on the out-of-order display surface 202 and the under-inspection display surface 203 are not limited to being printed, but may be displayed using a light source such as an LED. Furthermore, the characters displayed on the out-of-order display surface 202 and the under-inspection display surface 203 are not limited to "out-of-order" and "under inspection", but may be other display indicating that the use of the elevator 1 is restricted.
