Description

[Technical field]

[0001] The present invention relates to a threshold positioning support device for positioning a threshold installed at an elevator entrance. [Background technology]

[0002] In Japan, due to the declining birthrate and aging population, people are avoiding work at construction sites, etc., and the decrease in construction workers, especially skilled workers, is an issue. There is a demand for more efficient and labor-saving construction work so that the same number of construction projects can be handled even with a decrease in the number of workers.

[0003] Elevator installation involves a wide variety of tasks, including measuring inside the tower, installing the rails, installing the entrances and exits, installing equipment inside the tower, assembling the car, and wiring. Among these installation tasks, entrance and exit installation involves setting up an openable door at the opening of the elevator shaft. Since entrance and exit installation is a task that is repeated on each floor of the building and involves handling long materials and heavy objects, it is labor-intensive and time-consuming.

[0004] The installation of elevator entrances and exits mainly involves the installation of the sill, jamb, and door pocket to the building. The sill forms the foundation of the entrance and is the part that guides the door when it slides open and closes. The installation work of the sill requires precise adjustment of the position of the sill in each direction of the six degrees of freedom, such as keeping the gap between the car ascending and descending in the elevator shaft and the sill of each floor constant, and installing the sill horizontally to allow the door to open and close smoothly. The six degrees of freedom here refer to the six directions: X-axis, Y-axis, Z-axis, pitch, roll, and yaw.

[0005] When adjusting the position of a threshold with high precision during installation work of the threshold, it is possible to use a device or a jig that helps to make the adjustment work more efficient and reduce the labor required.

[0006] Patent Document 1 proposes a technique relating to an elevator hall threshold adjustment jig and threshold adjustment method.

[0007] Patent Document 1 discloses a technology in which an adjustment jig with centering notches formed on the top and bottom is attached to thresholds near the left and right vertical frames of a jamb, and a piano wire is used to adjust the position of the thresholds, aligning them with the notches of each adjustment jig.

[0008] [Patent Document 1] JP 2014-28672 A Summary of the Invention [Problem to be solved by the invention]

[0009] First, the configuration of the equipment when the threshold 1 is installed at the opening 4 of the building will be described with reference to Figs. 1 to 4. Fig. 1 is a perspective view from the elevator shaft side showing the configuration of the threshold 1 and bracket 2 installed at the opening 4. Here, the coordinate system used in this specification will be described. In Fig. 1, the X-axis direction indicates the direction of entrance and exit of the elevator, the Y-axis direction indicates the width direction of the elevator entrance, and the Z-axis direction indicates the height direction of the elevator. In addition, the roll direction indicates the direction of rotation around the X-axis, the pitch direction indicates the direction of rotation around the Y-axis, and the yaw direction indicates the direction of rotation around the Z-axis. The X-axis and Y-axis directions correspond to two horizontal axes that are two axes parallel to the horizontal plane, and the Z-axis direction corresponds to the vertical direction that is perpendicular to the horizontal plane. In addition, the direction of entrance and exit of the elevator corresponds to the depth (front-back) direction when looking at the elevator shaft from the elevator landing, that is, the direction in which people enter and exit, and the width (left-right) direction of the elevator entrance corresponds to the direction in which the elevator door opens and closes.

[0010] In front of the opening 4 on the hoistway 6 side, two reference cores 3 that serve as positioning references for the threshold 1 are suspended vertically from the top to the bottom of the hoistway 6. A thin wire such as piano wire with a diameter of about 0.5 mm is used for the reference cores 3. The two reference cores 3 are installed so that the distance between them is the opening width of the doorway frame to be installed. The threshold 1 is installed on top of multiple brackets 2 that are attached to the wall surface 11 or steel frame inside the hoistway.

[0011] Fig. 2 is a diagram showing the basic configuration of the threshold 1 and bracket 2. Fig. 3 is an enlarged view of the bracket 2. The bracket 2 consists of two pieces, a wall-side bracket 2a and a threshold-side bracket 2b, and is fastened with a bracket bolt 12. Note that, in order to allow the mounting positions of the wall-side bracket 2a and the threshold-side bracket 2b to be adjusted, oblong holes 17 as shown in Fig. 3 are provided in the wall-side bracket 2a and the threshold-side bracket 2b.

[0012] Figure 4 is a top view of the threshold 1. The threshold 1 is formed with a groove 18 that serves as a guide when the entrance door is opened and closed, and the groove 18 is provided with garbage holes 14 at several points. In addition, two opening marking lines 13 are drawn on the top surface of the threshold 1. These opening marking lines 13 are used when positioning the horizontal surface of the threshold 1, and the position of the threshold 1 is adjusted so that the two reference centers 3 mentioned above are on the extension lines of the opening marking lines 13. Furthermore, the height of the threshold 1 is adjusted so that the top surface of the threshold 1 coincides with a position a specified distance below the return mark set by the architect near the opening.

[0013] As described above, in the conventional threshold position adjustment work, the threshold 1 is temporarily fixed on the bracket 2 that is fixed in advance to the wall surface 11 in the elevator, and the worker adjusts the posture and position of the threshold by hitting the bracket 2 or the threshold 1 with a hammer using two reference axes 3 and a level in front of the opening as references. However, in this method, the movement direction, angle, and movement amount of the threshold 1 change depending on the tightening of the bolt when the threshold 1 is temporarily fixed, the hitting position of the hammer, the hitting angle, and the strength of the hitting force. For this reason, it is difficult for the worker to adjust the position of the threshold 1 as intended, and skilled skills and know-how are required. In addition, there is a problem that an inexperienced worker has to hit the threshold with a hammer many times before completing the position adjustment of the threshold 1, which takes a long time to work.

[0014] Regarding such a problem, the elevator hall threshold adjustment jig described in Patent Document 1 is merely an indicator plate for easily visually checking the positional relationship between the piano wire hanging from the top of the elevator shaft and the notches of the upper and lower adjustment pieces of the threshold adjustment jig. Therefore, even when using the elevator hall threshold adjustment jig described in Patent Document 1, the worker needs to strike the threshold with a hammer while visually checking the positional relationship between the piano wire and the notch. Therefore, skilled techniques are required to adjust the position of the threshold. In addition, when the device that adjusts the position of the threshold is driven by electricity, a storage battery is required to supply power to the device, but if the device consumes a lot of power, the remaining charge of the storage battery decreases and the device cannot be operated.

[0015] An object of the present invention is to provide a threshold positioning assistance device that simplifies the adjustment of the threshold position and reduces power consumption when the device is in operation. [Means for solving the problem]

[0016] In order to achieve the above-mentioned object, the present invention provides a threshold positioning assistance device for adjusting the position of a threshold installed at the entrance / exit of an elevator shaft, comprising an adjustment mechanism for supporting the threshold and adjusting the height and inclination of the threshold, and an operation controller installed at the threshold and controlling the adjustment mechanism, the operation controller comprising a sensor for measuring the inclination of the threshold, a calculation means for calculating a control amount based on inclination information measured by the sensor, a wireless communication means for wirelessly transmitting the calculation result of the calculation means to the adjustment mechanism, and a power source for supplying power to the wireless communication means, wherein the calculation means stops wireless transmission from the wireless communication means when the inclination information measured by the sensor is within a predetermined inclination range, and wirelessly transmits a control signal from the wireless communication means to the adjustment mechanism when the inclination information measured by the sensor is outside the predetermined inclination range. Effect of the Invention

[0017] According to the present invention, it is possible to provide a threshold positioning support device that simplifies the position adjustment of the threshold and reduces the power consumption when the device is in operation. Problems, configurations, and effects other than those described above will become clear from the description of the following embodiments. [Brief description of the drawings]

[0019] The following describes a threshold positioning support device according to an embodiment. The drawings referred to in the following description are schematic diagrams of the embodiment, so the scale, intervals, and positional relationships of each component may be exaggerated, or some components may not be shown. In the following description, the same names and symbols generally indicate the same or similar components, and detailed descriptions will be omitted as appropriate. One embodiment of the present invention will be described.

[0020] First Embodiment (Device configuration) 5 is a perspective view showing the configuration of a threshold positioning support device 100 according to the first embodiment of the present invention. The coordinate system is the same as that defined in FIG.

[0021] The threshold positioning support device 100 is a device used when installing a threshold 1 at the entrance / exit portion of an elevator. As shown in Fig. 1, the threshold positioning support device 100 is mainly composed of a pair of adjustment mechanisms 101 installed side by side on the left and right opening side surfaces 7 of the opening 4, and a control device 113 that controls the adjustment mechanisms 101.

[0022] Next, details of the adjustment mechanism 101 will be described. Fig. 6 is a perspective view of the adjustment mechanism 101. Fig. 7 is a view of the adjustment mechanism 101 seen from the Y direction. Fig. 8 is a view of the adjustment mechanism 101 seen from the X direction (the platform side).

[0023] The adjustment mechanism 101 mainly consists of a support arm 102 on which the threshold 1 is placed, a horizontal position adjustment unit 103 that adjusts the position of the support arm 102 in the width direction of the entrance (Y axis), a height adjustment unit 104 that adjusts the height (Z axis) of the support arm 102, a fore-aft inclination adjustment unit 105 that adjusts the inclination of the support arm 102 in the depth direction of the entrance (Pitch axis), and a base plate 106.

[0024] As shown in FIG. 5, the adjustment mechanism 101 is attached by clamping the wall of the opening side surface 7 and the base plate 106 with a clamp 8 while the base plate 106 is in close contact with the opening side surface 7 .

[0025] The horizontal position adjustment unit 103 is composed of two upper and lower parallel brackets 112 and a horizontal position fixing knob 99. The parallel brackets 112 are fixed to the base plate 106 with two bolts 98, and are structured so that the Y-direction positions of the support arm 102, height adjustment unit 104, and front-rear tilt adjustment unit 105 can be changed using the long holes 118 of the parallel brackets 112 as guides. The Y-direction positions can be changed by loosening the two upper and lower horizontal position fixing knobs 99, and the Y-direction positions can be fixed by tightening the horizontal position fixing knob 99.

[0026] The height adjustment unit 104 is installed between two parallel brackets 112, one above and one below, of the horizontal position adjustment unit 103, and is mainly composed of an actuator 107, a sliding bracket 108, a control device 113 for the actuator 107, two guide shafts 115, a back plate 114, and a fixed plate 119. In this embodiment, the actuator 107 is assumed to be an electric linear actuator. A sliding bracket 108 is connected to the tip of the actuator 107, and the sliding bracket 108 moves in the vertical (Z-axis) direction along two guide shafts 115 installed between two fixed plates 119, one above and one below. A support leg 111 is installed on the back plate 114. This is for stabilizing the adjustment mechanism 101 by placing its own weight on the support leg 111 when it is desired to mount the base plate 106 floating without contacting the building floor 5. Therefore, the support leg 111 can be moved up and down by loosening the thumbscrew 150, and is fixed in place by contacting it with the building floor 5 and tightening the thumbscrew 150.

[0027] The longitudinal tilt adjustment unit 105 is mainly composed of an arm support bracket 121, a rotating shaft 109, and an adjustment screw support bracket 122. By rotating the two longitudinal tilt adjustment screws 110 about the rotating shaft 109 to push up the arm support bracket 121, the longitudinal tilt (pitch axis) angle of the support arm 102 fixed to the arm support bracket 121 can be changed.

[0028] The support arm 102 is fixed to the arm support bracket 121 with a support arm position adjustment knob 116. The support arm 102 is provided with a support arm upper long hole 117, which is used when moving the position of the support arm 102 in the front-back (X-axis) direction. A threshold fixing bracket 155 and a threshold fixing knob 157 are installed on the support arm 102, penetrating the support arm 102.

[0029] Here, a method for temporarily fixing the threshold 1 to the support arm 102 will be described. With the threshold fixing knob 157 loosened in advance, i.e. with the gap between the top surface of the support arm 102 and the upper lower surface of the U-shape of the threshold fixing bracket 155 large, the threshold 1 is placed on the support arm 102 and clamped by the threshold fixing bracket 155 (the state shown in FIG. 5). Thereafter, by tightening the threshold fixing knob 157, the threshold 1 is clamped between the support arm 102 and the threshold fixing bracket 155 and temporarily fixed. Before the threshold fixing knob 157 is tightened, the threshold 1 can be moved in the XY directions on the support arm 102.

[0030] 5, a plate 190 having a U-shape as viewed from the Y direction is placed above the threshold 1. An operation controller 160 and a height indicator scale 161 are mounted above the plate 190. Here, the operation controller 160 will be described in detail.

[0031] 9 is a front view of the operation controller 160. The operation controller 160 is provided with a power switch 159, an automatic / manual changeover button 163, an operation button 164, a zero point setting button 167, and an LED 169. The actuator 107 can be controlled manually by switching to manual mode with the automatic / manual changeover button 163 and having an operator operate the operation button 164. The zero point setting button 167 makes it possible to set the zero point of the tilt sensor. Details will be explained in the system configuration below. The above is the basic mechanical configuration of the threshold positioning support device 100.

[0032] (System Configuration) Next, the configuration of threshold positioning support device 100 will be described with reference to Fig. 10. Fig. 10 is a block diagram of threshold positioning support device 100.

[0033] The operation controller 160 includes a microcomputer 162, an operation button 164, a power source 166 that supplies power to the microcomputer 162, a sensor (tilt sensor 168) that measures the inclination of the threshold 1, and an LED 169. In this embodiment, a storage battery is used as the power source 166. The storage battery may be of a rechargeable type or a disposable type.

[0034] The control device 113 includes a microcomputer 170 that controls the actuator 107, and a power source 172 that supplies power to the microcomputer 170 and the actuator 107. In this embodiment, a storage battery is used as the power source 172. The storage battery may be of a rechargeable type or a disposable type.

[0035] When the operation button 164 of the operation controller 160 is operated, the microcomputer 162 of the operation controller 160 wirelessly transmits a control signal corresponding to the input to the control device 113 of the actuator 107, and the microcomputer 170 of the control device 113 receiving the control signal controls the actuator.

[0036] Next, the control mode will be described. The threshold positioning assistance device has two control modes, one is a manual mode and the other is an automatic horizontal control mode. These modes are switched by the automatic / manual switching button 163.

[0037] In the manual mode, the operator operates the operation button 164, and the operation information of the operation button is input into the microcomputer 162, which calculates a command value based on the operation information and transmits it wirelessly to the microcomputer 170 to control the actuators 107 mounted on the left and right adjustment mechanisms 101.

[0038] Next, the automatic horizontal control mode will be described with reference to Fig. 11. Fig. 11 is a flowchart of the automatic horizontal control. As an example, the right-side adjustment mechanism 101 is set as the master, and the left-side adjustment mechanism is controlled as the slave so that the value of the tilt sensor 168 becomes 0 degrees (horizontal).

[0039] Right-side adjustment mechanism 101 inputs operation information of operation button 164 corresponding to the right-side adjustment mechanism into microcomputer 162, similar to the above-mentioned manual control (step S1).

[0040] Next, the microcomputer 162 obtains the value of the tilt sensor 168 and measures the tilt angle (step S2).

[0041] Based on the data on the tilt angle, the microcomputer 162 changes the increment to be added to the current command value for the left actuator 107, and adds or subtracts the increment to the command value (step S3).

[0042] Thereafter, the microcomputer 162 judges the measured tilt angle data (step S4), and if the tilt angle is within ±0.08 degrees, turns off the wireless communication (step S5).

[0043] If the inclination angle is greater than ±0.08 degrees, command values ​​(control signals) for the left and right actuators 107 are wirelessly transmitted to the microcomputer 170 to control the actuators 107 (step S6). This control is repeated to keep the threshold horizontal.

[0044] The microcomputer 162 determines whether the automatic / manual switching button 163 has been pressed (step S7), and if the automatic / manual switching button 163 has been pressed (Yes in step S7), the microcomputer 162 repeats the process from step S1. If the automatic / manual switching button 163 has not been pressed (No in step S7), the microcomputer 162 ends the process.

[0045] Here, details of the processing of data from tilt sensor 168 will be described with reference to Fig. 12. Fig. 12 is a block diagram of microcomputer 162 showing the flow of processing data (tilt information) from tilt sensor 168.

[0046] The data (tilt information) from the tilt sensor 168 is filtered by a filter processing means 180. For example, a Madgwick filter is used for this filtering process. The filtered tilt information is averaged by an averaging processing means 182 (up to this point is step S2 in FIG. 11).

[0047] The attitude angle determination means 184 determines whether the averaged data is within the range of the attitude angle adjustment target (step S4 in FIG. 11). If it is within the range, the attitude angle determination means 184 issues a command to the wireless control means 186 to stop the function of the wireless communication means 188 (step S5 in FIG. 11). If it is outside the range, the attitude angle determination means 184 issues a command to the wireless control means 186 to operate the wireless communication means 188 and transmit a command value to the microcomputer 170 (step S6 in FIG. 11). The attitude angle determination means 184 operates as a calculation means that calculates a control amount based on the tilt information measured by the tilt sensor 168. Furthermore, if the tilt information measured by the tilt sensor 168 is within a predetermined tilt range, the attitude angle determination means 184 operates to stop wireless transmission from the wireless communication means 188, and if the tilt information measured by the tilt sensor 168 is outside the predetermined tilt range, it operates to wirelessly transmit a control signal from the wireless communication means 188 to the adjustment mechanism 101. Since the wireless communication means 188 operates using power supplied from the power source 166, if the wireless communication means 188 is constantly operating, the remaining power of the power source 166 will decrease. Therefore, in this embodiment, when the tilt information measured by the tilt sensor 168 is within a predetermined range of tilt, wireless transmission from the wireless communication means 188 is stopped, thereby reducing the power consumption of the power source 166.

[0048] (Threshold installation method) Next, a threshold installation method using the threshold positioning support device according to this embodiment will be described with reference to Figures 13 and 14. Figure 13 is a flowchart of the threshold installation method using the threshold positioning support device. Figure 14 is a view of the opening 4 seen from the landing side before the threshold is installed.

[0049] First, as shown in Fig. 14, the worker draws the finishing line 16 at a position a specified distance below the relief mark 15 that has been previously marked (step S11). The relief mark 15 is a line drawn horizontally on the wall surface beside the opening 4, and is often drawn about 1 m above the surface that will become the floor after construction is completed. In this case, the worker draws the finishing line 16 horizontally 1 m below the relief mark 15.

[0050] Next, as shown in FIG. 14, the worker places a laser marking tool 9 on the building floor 5 in front of the opening 4, and irradiates a horizontal laser line 10 toward the opening 4 (step S12).

[0051] After that, the distance H between the finishing line 16 and the horizontal laser line 10 is measured with a ruler and recorded (step S13). This distance H is used when adjusting the height of the threshold 1. Next, the standard distance from the center position of the anchor bolt hole of the wall-side bracket 2a in Fig. 2 to the upper surface of the threshold (the distance when the bracket bolt 12 is at the center of the elongated hole 17) is marked horizontally on the wall surface inside the elevator shaft below the finishing line 16, holes are drilled at the bracket intervals in Fig. 2, and the anchor bolts are installed (step S14).

[0052] Next, the worker takes the assembled sill 1 and bracket 2 as shown in Fig. 2 into the hoistway and temporarily fixes it to the wall with anchor bolts (step S15). A gondola or a work platform that can be raised and lowered is provided in the hoistway.

[0053] Next, the worker installs the adjustment mechanism 101 of the threshold positioning support device 100 by fixing it to the opening side surface 7 with the clamp 8 as shown in Fig. 5 (step S16). When installing the adjustment mechanism 101, the horizontal position adjustment part 103 of the adjustment mechanism 101 is used to adjust the position of the height adjustment part 104 so that the reference center 3 and the support arm 102 of the adjustment mechanism 101 do not come into contact with each other. In addition, the support arm position adjustment knob 116 is loosened to pull the support arm 102 out toward the elevator shaft so that it does not interfere with the threshold 1.

[0054] Next, the worker loosens the bracket bolt 12 between the wall-side bracket 2a and the threshold-side bracket 2b to make the threshold 1 adjustable, and places the threshold 1 on the support arm 102 of the adjustment mechanism 101 as shown in Fig. 5 (step S17). When placing the threshold 1, the worker loosens the support arm position adjustment knob 116, lifts the threshold 1, and pushes in the support arm 102 that has been pulled out to the hoistway side with the other hand to place the threshold 1 on the support arm 102. This operation is performed for both the left and right adjustment mechanisms. After placing, the threshold 1 is temporarily fixed by being sandwiched between the support arm 102 and the threshold fixing bracket 155 by tightening the threshold fixing knob 157.

[0055] Next, the worker installs the operation controller 160 on the upper surface of the threshold 1 (step S18). This completes the installation of the threshold positioning support device, resulting in the equipment layout shown in Fig. 5. Next, the positioning work for the threshold 1 will be performed.

[0056] First, the front-to-rear inclination of the threshold 1 is adjusted to be horizontal (step S19). To adjust the front-to-rear inclination, a level is placed on the top surface of the threshold 1, and the angle is adjusted with the front-to-rear inclination adjustment screw 110 while checking the position of the air bubble so that it is horizontal.

[0057] Next, the threshold positioning assistance device 100 is powered on, the automatic horizontal control mode is enabled, and the left and right inclination (Roll axis) of the threshold is made horizontal (step S20).

[0058] Next, the installation height of the threshold 1 is adjusted. The actuator of the right-side adjustment mechanism 101 is operated with the operation button 164 of the operation controller 160, and the height of the threshold 1 is adjusted so that the horizontal laser line 10 emitted from the laser mark 9 projected on the height index scale 161 is at a distance H from the upper surface of the threshold. At this time, since the threshold positioning support device 100 is in the automatic horizontal control mode, the height is adjusted while maintaining the left-right horizontality of the threshold 1. Once the height of the threshold 1 has been determined, the command value is held by operating the switch, and the movement of the actuator 107 is stopped (step S21).

[0059] Next, the bracket bolts 12 between the wall-side bracket 2a and the threshold-side bracket 2b are temporarily tightened (step S22). This completes the adjustment of the inclination of the threshold 1 in the front-back (pitch axis) and left-right (roll axis) directions and the adjustment of the installation height (Z axis).

[0060] Next, the bolt between the threshold 1 and the threshold-side bracket 2b is loosened (step S23). Furthermore, the threshold fixing knob 157 is loosened to release the temporary fixation of the threshold 1. This allows the threshold 1 to be adjusted in the horizontal plane (X-axis, Y-axis, Yaw-axis) on the threshold-side bracket 2b.

[0061] Thereafter, the position of the punch stamped on the side of the threshold 1 placed on the support arm 102 is aligned with the reference core 3, and at the same time, the distance between the reference core 3 and the threshold 1 is adjusted to a predetermined distance, thereby completing the positioning of the threshold 1 on the horizontal plane (step S24).

[0062] Next, the threshold 1 is temporarily fixed by tightening the threshold fixing knob 157 again so that the positioned threshold 1 does not shift, and the bolt between the threshold 1 and the threshold side bracket 2b is temporarily tightened (step S25).

[0063] Next, a spirit level is placed on the threshold 1 to check the position of the threshold 1, and the height index scale 161 is used to recheck the distance to the reference center 3 and the matching state with the finishing line 16 (step S26). After the check is completed, the anchor bolts, the bolts between the brackets, and the bolts between the sill and the brackets, which were temporarily tightened, are tightened and fixed (step S27). This completes the work of fixing the sill.

[0064] Finally, the threshold fixing knob 157 is loosened to release the fixation between the threshold 1 and the support arm 102, the support arm position adjustment knob 116 is loosened to pull out the support arm 102 to the elevator shaft side, and the clamp 8 is released in this state, and the left and right adjustment devices 101 and the operation controller 160 of the threshold positioning support device 100 are removed (step S28).

[0065] (effect) By filtering and averaging the information from the tilt sensor, it is possible to reduce the variation in tilt data, which has a large variance, and to control it to be stable and level. This allows the tilt angle to be stably within a specified range, and by turning off the wireless function, it is possible to reduce the power consumption of the microcontroller. In addition, by reducing the power consumption of the microcontroller, the battery (power source) life can be extended. Furthermore, by extending the battery life, the time required for maintenance work such as battery replacement and charging can be shortened.

[0066] Furthermore, the worker performing the threshold installation work does not need to support the weight of the threshold 1 when adjusting the threshold 1. Also, by using the threshold positioning support device 100, it is possible to adjust the position and orientation of the threshold 1, which was previously difficult to do during the installation work of the threshold 1, and it is now possible to adjust the inclination angle and position of the threshold 1 without having to strike the threshold 1 with a hammer as in the past. This makes the threshold installation work easier and shortens the work time compared to conventional methods.

[0067] Furthermore, since the operation controller 160 and the control device 113 are configured to communicate wirelessly, control cables and the like are not required, and by positioning the support arm as close as possible to the opening side 7, the area through which workers can pass can be kept wide and safe.

[0068] <Second embodiment> In the first embodiment, the control device 113 and the operation controller 160 are directly connected wirelessly, but in the second embodiment, for example, a wireless LAN access point connected to a server may be installed, and the control device 113 and the operation controller 160 may be connected via the wireless LAN access point. When a wireless LAN access point is installed, data on the inclination angle of the threshold 1 held by the microcomputer 162, for example, posture information when the inclination angle falls within a predetermined range, can be wirelessly transmitted to the access point, so that data during construction can be stored in the server. This can be used for evaluation of installation quality, etc.

[0069] <Modifications, etc.> The present invention is not limited to the above-described embodiment, but includes various modified examples. For example, the above-described embodiment has been described in detail to facilitate understanding of the contents of the present invention, but the present invention is not necessarily limited to having all the configurations described in the above-described embodiment. It is also possible to replace a part of the configuration of one embodiment with the configuration of another embodiment. It is also possible to add the configuration of another embodiment to the configuration of one embodiment. It is also possible to delete a part of the configuration of each embodiment, add another configuration, or replace it with another configuration.

[0070] In addition, the above-mentioned configurations, functions, processing units, processing means, etc. may be realized in part or in whole by hardware, for example, by designing them as integrated circuits. In addition, the above-mentioned configurations, functions, etc. may be realized in software by a processor interpreting and executing a program that realizes each function. Information such as the program, table, file, etc. that realizes each function can be stored in a memory, a recording device such as a hard disk or SSD (Solid State Drive), or a recording medium such as an IC card, SD card, or DVD.

[0071] In addition, the control lines and information lines shown are those that are considered necessary for the explanation, and not all control lines and information lines in the product are necessarily shown. In reality, it can be considered that almost all components are connected to each other.

[0072] For example, in the above embodiment, the height adjustment unit 104 of the adjustment mechanism 101 uses an electric actuator 107, but this may be replaced with a manual operation, and the actuator 107 may be configured so that the sliding bracket 108 moves up and down using a ball screw with an adjustment knob. Conversely, the mechanism of the front-rear tilt adjustment screw 110, which has been manually operated, may be motorized. [Explanation of symbols]
