Description

Technical Field

[0001] The present invention relates to a threshold positioning auxiliary device for positioning a threshold arranged at an elevator entrance or exit. Background Art

[0002] In Japan, with the declining birthrate and aging population, people are staying away from work at construction sites, and the reduction in the number of construction workers has become a problem, especially the reduction in skilled workers. We seek to improve the efficiency and labor saving of construction work so that the number of construction works can be handled as before even with a reduced number of workers.

[0003] Elevator installation work includes various operations such as tower measurement, track installation, door installation, tower equipment installation, car assembly, wiring, etc. Among these installation operations, door installation is the operation of installing a door that can be opened and closed at the opening of the elevator shaft. Door installation is a work that is repeated on each floor of the building, and it is a work that handles long parts and heavy objects, so it requires labor and time.

[0004] The installation of elevator entrances and exits mainly involves setting door thresholds (sills), door frames, and door covers on buildings. The door threshold is the foundation of the entrance and exit, and is a part that guides the sliding of the door. In the installation of the door threshold, it is required to fix the gap between the elevator car that is raised and lowered in the elevator shaft and the door threshold of each floor, or to install the door threshold horizontally in order to smoothly move the door to open and close, and adjust the position of the door threshold with high precision in each direction of the six degrees of freedom. Here, the six degrees of freedom are the six directions of freedom consisting of the X-axis direction, the Y-axis direction, the Z-axis direction, the pitch direction, the roll direction, and the yaw direction.

[0005] In the installation work of the door sill, when the position of the door sill is adjusted with high precision, it is conceivable to use a device or a jig that assists in improving the efficiency of the adjustment work and reducing the labor.

[0006] As a technology related to an elevator hall threshold adjustment jig and a threshold adjustment method, the technology described in Patent Document 1 has been proposed.

[0007] Patent Document 1 discloses a technique in which adjustment jigs having notches formed on the top and bottom for centering are mounted on door sills near left and right vertical frames of a door frame, and piano wires for adjusting the position of the door sills are aligned with the notches of the adjustment jigs.

[0011] Problems to be solved by the invention

[0012] First, use Figure 1 to Figure 4 The structure of the equipment in the case where the threshold 1 is provided at the opening 4 of the building will be described. Figure 1 1 is a perspective view showing the structure of the door sill 1 and the bracket 2 provided in the opening 4, viewed from the side of the elevator passage. Here, the coordinate system used in this specification is explained. Figure 1 In the figure, the X-axis direction indicates the direction of the elevator's entry and exit, the Y-axis direction indicates the width direction of the elevator's entrance and exit, and the Z-axis direction indicates the height direction of the elevator. In addition, the roll direction indicates the rotation direction around the X-axis, the pitch direction indicates the rotation direction around the Y-axis, and the yaw direction indicates the rotation direction around the Z-axis. The X-axis direction and the Y-axis direction are equivalent to the two axial directions parallel to the horizontal plane, namely the horizontal two-axis directions, and the Z-axis direction is equivalent to the direction orthogonal to the horizontal plane, namely the vertical direction. In addition, the elevator's entry and exit direction is equivalent to the depth (front and back) direction when observing the lifting channel from the elevator's lobby, that is, the direction in which people enter and exit, and the width (left and right) direction of the elevator's entrance and exit is equivalent to the direction of the elevator's door switch.

[0013] In front of the opening 4 on the side of the lifting passage 6, two reference cores 3 serving as the positioning reference of the threshold 1 are suspended vertically from the top to the bottom of the lifting passage 6. The reference core 3 uses a thin wire such as a piano wire with a diameter of about 0.5 mm. In addition, it is installed in a manner that the interval between the two reference cores 3 becomes the opening width of the frame of the entrance and exit to be set. The threshold 1 is set on the wall surface 11 in the lifting passage or on a plurality of brackets 2 installed on the steel frame.

[0014] Figure 2 1 is a diagram showing the basic structure of the door sill 1 and the bracket 2 . Figure 3 1 is an enlarged view of the bracket 2. The bracket 2 is composed of two parts, the wall side bracket 2a and the door sill side bracket 2b, which are fastened by the bracket bolts 12. In addition, in order to adjust the installation positions of the wall side bracket 2a and the door sill side bracket 2b, Figure 3 The elongated holes 17 shown are provided on the wall-side bracket 2a and the door-sill-side bracket 2b.

[0015] Figure 4 This is a top view of the threshold 1. The threshold 1 is formed with a groove 18 that serves as a guide for the door when opening and closing the entrance, and trash drop holes 14 are provided at multiple locations of the groove 18. In addition, two opening lines 13 are drawn on the upper surface of the threshold 1. The opening lines 13 are used when positioning the horizontal plane of the threshold 1, and the position of the threshold 1 is adjusted so that the two reference cores 3 mentioned above come to the extension line of the opening lines 13. In addition, the height of the threshold 1 is adjusted so that the upper surface of the threshold 1 coincides with the position below the predetermined distance from the mark set by the building near the opening.

[0016] As described above, in the existing threshold position adjustment operation, the threshold 1 is temporarily fixed on the bracket 2 which is previously fixed to the wall 11 in the lifting passage, and the operator uses the two reference cores 3 or the level meter located in front of the opening as a reference to hit the bracket 2 or the threshold 1 with a hammer, thereby adjusting the posture and position of the threshold. However, in this method, the moving direction, angle, and movement amount of the threshold 1 change according to the degree of tightening of the bolts when the threshold 1 is temporarily fixed, the hitting position of the hammer, the hitting angle, the increase or decrease of the hitting force, etc. Therefore, it is difficult for the operator to adjust the position of the threshold 1 as intended, and skilled skills and techniques are required. In addition, for unskilled operators, there is a problem that the operation takes a long time to hit the threshold with a hammer many times before the position adjustment of the threshold 1 is completed.

[0017] Regarding such a problem, the elevator lobby threshold adjustment fixture described in Patent Document 1 is nothing more than an identification plate for easily visually confirming the positional relationship between the piano wire hanging from the top of the lifting channel and the notches of the upper and lower adjustment pieces of the threshold adjustment fixture. Therefore, even when using the elevator lobby threshold adjustment fixture described in Patent Document 1, the operator needs to hit the threshold with a hammer while visually confirming the positional relationship between the piano wire and the notch. Therefore, the position adjustment of the threshold requires skilled skills. In addition, in the case of a device that is driven by electricity to adjust the position of the threshold, a battery is required to supply power to the device, but if the power consumption of the device is large, the remaining battery power is reduced and the device cannot be operated.

[0018] The object of the present invention is to provide a door sill positioning auxiliary device, which can simplify the position adjustment of the door sill and reduce the power consumption of the device when it is working.

[0019] Solutions to Solve Problems

[0020] In order to achieve the above-mentioned purpose, the present invention is a threshold positioning auxiliary device, which adjusts the position of the threshold of the entrance and exit of the elevator's lifting passage, and is characterized in that it comprises: an adjustment mechanism, which supports the threshold and adjusts the height and inclination of the threshold; and an operation controller, which is arranged on the threshold and controls the adjustment mechanism, and the operation controller comprises: a sensor, which measures the inclination of the threshold; a calculation unit, which calculates a control amount based on the inclination information measured by the sensor; a wireless communication unit, which wirelessly sends the calculation result of the calculation unit to the adjustment mechanism; and a power supply, which supplies power to the wireless communication unit, and the calculation unit stops the wireless transmission from the wireless communication unit when the inclination information measured by the sensor is within a predetermined inclination range, and wirelessly sends a control signal from the wireless communication unit to the adjustment mechanism when the inclination information measured by the sensor is outside the predetermined inclination range.

[0039] The following is a description of a threshold positioning assisting device according to an embodiment. In addition, the drawings referred to in the following description are diagrams schematically showing the embodiment, so the scales, intervals, positional relationships, etc. of each component are sometimes exaggerated, or the illustration of a part of the component is omitted. In addition, in the following description, the same names and figure numbers represent the same or homogeneous components in principle, and detailed descriptions are appropriately omitted. An embodiment of the present invention is described.

[0040] <First Embodiment>

[0041] (Device Structure)

[0042] Figure 5 is a perspective view showing the structure of the door sill positioning assisting device 100 according to the first embodiment of the present invention. Figure 1 The coordinate system is the same as defined in .

[0043] The threshold positioning auxiliary device 100 is a device used when the threshold 1 is installed at the entrance and exit of the elevator. Figure 1 As shown, the door sill positioning assisting device 100 is mainly composed of a pair of adjustment mechanisms 101 arranged side by side on the left and right opening side surfaces 7 of the opening portion 4 and a control device 113 for controlling the adjustment mechanisms 101 .

[0044] Next, the adjustment mechanism 101 will be described in detail. Figure 6 It is a perspective view of the adjustment mechanism 101 . Figure 7 This is a diagram of the adjustment mechanism 101 as viewed from the Y direction. Figure 8 This is a diagram of the adjustment mechanism 101 as viewed from the X direction (the entrance hall side).

[0045] The adjustment mechanism 101 is mainly composed of a support arm 102 for placing the door sill 1, a horizontal position adjustment unit 103 for adjusting the position of the entrance and exit of the support arm 102 relative to the width direction (Y axis), a height adjustment unit 104 for adjusting the height (Z axis) of the support arm 102, a front and rear tilt adjustment unit 105 for adjusting the tilt of the entrance and exit of the support arm 102 relative to the depth direction (Pitch axis), and a base plate 106.

[0046] like Figure 5 As shown, the adjustment mechanism 101 is installed by clamping the wall of the opening side surface 7 and the base plate 106 with the clamp 8 in a state where the base plate 106 is in close contact with the opening side surface 7 .

[0047] 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 bracket 112 is fixed to the base plate 106 by two bolts 98, and the long hole 118 of the parallel bracket 112 is used as a guide to change the Y-direction position of the support arm 102, the height adjustment unit 104, and the front-rear tilt adjustment unit 105. The position in the Y direction can be changed by loosening the upper and lower horizontal position fixing knobs 99, and the horizontal position fixing knobs 99 can be tightened to fix the position in the Y direction.

[0048] The height adjustment unit 104 is provided between the upper and lower parallel brackets 112 of the horizontal position adjustment unit 103, and is mainly composed of an actuator 107, a sliding bracket 108, a control device 113 of the actuator 107, two guide shafts 115, a back plate 114, and a fixed plate 119. In this embodiment, it is assumed that the actuator 107 is an electric linear actuator. The sliding bracket 108 is connected to the front end of the actuator 107, and the sliding bracket 108 is movable in the up and down (Z-axis) direction along the two guide shafts 115 provided between the upper and lower fixed plates 119. The back plate 114 is provided with a support leg 111. This is to stabilize the adjustment mechanism 101 by placing its own weight on the support leg 111 when the base plate 106 is to be installed in a floating manner without contacting the building floor 5. Therefore, the support leg 111 can be moved up and down by loosening the thumb screw 150, and can be fixed by contacting the building floor 5 and tightening the thumb screw 150.

[0049] The front-rear tilt adjustment unit 105 is mainly composed of an arm support bracket 121, a rotation shaft 109, and an adjustment screw support bracket 122. By rotating two front-rear tilt adjustment screws 110 about the rotation shaft 109 to push up the arm support bracket 121, the front-rear tilt (Pitch axis: pitch angle) angle of the support arm 102 fixed to the arm support bracket 121 can be changed.

[0050] The support arm 102 is fixed to the arm support bracket 121 by 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 the position of the support arm 102 is moved along the front-back (X-axis) direction. The threshold fixing fitting 155 and the threshold fixing knob 157 are provided on the support arm 102 so as to penetrate the support arm 102.

[0051] Here, a method for temporarily fixing the door sill 1 to the support arm 102 is described. In the state where the door sill fixing knob 157 is loosened in advance, that is, in the state where the gap between the upper surface of the support arm 102 and the upper lower surface of the U-shaped door sill fixing fitting 155 is increased, the door sill 1 is placed on the support arm 102 and clamped by the door sill fixing fitting 155 ( Figure 5Then, by tightening the door sill fixing knob 157, the door sill 1 is sandwiched between the support arm 102 and the door sill fixing fitting 155 and is temporarily fixed. In the state before tightening the door sill fixing knob 157, the door sill 1 can move on the support arm 102 in the XY direction.

[0052] like Figure 5 As shown, a plate 190 having a U-shape when viewed from the Y direction is placed above the door sill 1. An operation controller 160 and a height index scale 161 are mounted above the plate 190. Here, the operation controller 160 will be described in detail.

[0053] Fig. 9 1 is a front view of the operation controller 160. The operation controller 160 is provided with a power switch 159, an automatic / manual switching button 163, an operation button 164, a zero point setting button 167, and an LED 169. The automatic / manual switching button 163 is set to the manual mode, and the operator operates the operation button 164, so that the actuator 107 can be controlled by human operation. The zero point setting button 167 can set the zero point of the tilt sensor. The details are described in the system structure described later. The above is the basic mechanical structure of the threshold positioning auxiliary device 100.

[0054] (System Structure)

[0055] Next, use Fig.10 The structure of the door sill positioning assisting device 100 will be described. Fig.10 is a block diagram of the door sill positioning assisting device 100 .

[0056] The operation controller 160 includes a microcomputer 162 (microcomputer), an operation button 164, a power supply 166 for supplying power to the microcomputer 162, a sensor (tilt sensor 168) for measuring the inclination of the door sill 1, and an LED 169. In this embodiment, a storage battery (battery) is used as the power supply 166. The storage battery (battery) may be a rechargeable type or a disposable type.

[0057] The control device 113 includes a microcomputer 170 (microcomputer) for controlling the actuator 107 and a power source 172 for supplying power to the microcomputer 170 and the actuator 107. In this embodiment, a storage battery (battery) is used as the power source 172. The storage battery (battery) may be rechargeable or disposable.

[0058] 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 that receives the control signal controls the actuator.

[0059] Next, the control mode is described. The door sill positioning assisting device has two control modes, one is a manual mode and the other is an automatic level control mode. The switching between these modes is performed by the automatic / manual switching button 163.

[0060] In the manual mode, the operator operates the operation button 164 to input the operation information of the operation button into the microcomputer 162, calculates the command value based on the operation information, and sends it wirelessly to the microcomputer 170 to control the actuator 107 mounted on the left and right adjustment mechanisms 101.

[0061] Next, use Fig.11 The automatic level control mode is described. Fig.11 2 is a flowchart of the automatic horizontal control, which shows, as an example, a state in which the right adjustment mechanism 101 is controlled as the master and the left adjustment mechanism is controlled as the slave so that the value of the tilt sensor 168 becomes 0 degrees (horizontal).

[0062] The right adjustment mechanism 101 imports the operation information of the operation button 164 corresponding to the right adjustment mechanism into the microcomputer 162 in the same manner as in the aforementioned manual control (step S1).

[0063] Next, the microcomputer 162 obtains the value of the tilt sensor 168 and measures the tilt angle (step S2).

[0064] The microcomputer 162 changes the increment to be added to the current command value of the left actuator 107 based on the data of the tilt angle, and adds or subtracts the increment to the command value (step S3).

[0065] Next, the microcomputer 162 determines the data of the measured tilt angle (step S4), and turns off the wireless when the tilt angle is within ±0.08 degrees (step S5).

[0066] When the tilt angle is larger than ±0.08 degrees, the command values ​​(control signals) of the left and right actuators 107 are wirelessly transmitted to the microcomputer 170 to control the actuators 107 (step S6). By repeating this control, the door sill is controlled to be horizontal.

[0067] The microcomputer 162 determines whether the automatic / manual switching button 163 is pressed (step S7). If the automatic / manual switching button 163 is pressed ("Yes" in step S7), the processing from step S1 is repeated. If the automatic / manual switching button 163 is not pressed ("No" in step S7), the processing ends.

[0068] Among them, use Fig.12 The details of data processing by the tilt sensor 168 will be described. Fig.12This is a block diagram of the microcomputer 162 showing the flow of processing of data (tilt information) from the tilt sensor 168 .

[0069] The data (tilt information) of the tilt sensor 168 is filtered by the filtering unit 180. The filtering process uses, for example, a Madgwick filter. The filtered tilt information is averaged by the averaging unit 182 (so far, Fig.11 Step S2).

[0070] Regarding the averaged data, the attitude angle determination unit 184 determines whether it is within the attitude angle adjustment target range ( Fig.11 Step S4). If the position is within the range, the attitude angle determination unit 184 instructs the wireless control unit 186 to stop the function of the wireless communication unit 188 ( Fig.11 Step S5). When it is out of the range, the attitude angle determination unit 184 instructs the wireless control unit 186 to operate the wireless communication unit 188 and send the instruction value to the microcomputer 170 ( Fig.11 Step S6). The attitude angle determination unit 184 operates as a calculation unit that calculates the control amount based on the tilt information measured by the tilt sensor 168. And the attitude angle determination unit 184 operates as follows: when the tilt information measured by the tilt sensor 168 is within a predetermined tilt range, the wireless transmission from the wireless communication unit 188 is stopped, and when the tilt information measured by the tilt sensor 168 is outside the predetermined tilt range, the control signal is wirelessly sent from the wireless communication unit 188 to the adjustment mechanism 101. The wireless communication unit 188 uses the power supplied from the power supply 166 to operate, so if the wireless communication unit 188 is always operating, the remaining power of the power supply 166 is reduced. Therefore, in the present embodiment, when the tilt information measured by the tilt sensor 168 is within a predetermined tilt range, the wireless transmission from the wireless communication unit 188 is stopped to reduce the power consumption of the power supply 166.

[0071] (Threshold installation method)

[0072] Next, use Fig.13 , Fig.14 A method for installing a side sill using the side sill positioning assisting device according to the present embodiment will be described. Fig.13 The present invention is a flow chart of a method for installing a threshold using a threshold positioning aid. Fig.14 This is a diagram showing the opening 4 as viewed from the entrance hall side before the door threshold is installed.

[0073] First, if Fig.14As shown, the operator draws the finishing line 16 at a position away from the previously applied avoidance ink 15 by a predetermined dimension downward (step S11). The avoidance ink 15 is a line drawn horizontally on the wall surface next to the opening 4, and is usually drawn upward about 1m from the surface that becomes the floor after the construction is completed. In this case, the operator draws the finishing line 16 horizontally 1m downward from the avoidance ink 15.

[0074] Then, if Fig.14 As shown, the operator places the laser marking device 9 on the building floor 5 in front of the opening 4 and irradiates the horizontal laser line 10 toward the opening 4 (step S12).

[0075] After that, the distance H between the finish line 16 and the horizontal laser line 10 is measured and recorded in advance with a ruler (step S13). This distance H is used when adjusting the height of the threshold 1. Figure 2 The standard distance from the center of the anchor bolt hole of the wall side bracket 2a to the upper surface of the threshold (the distance when the bracket bolt 12 is located at the center of the long hole 17) is marked horizontally on the wall surface of the lifting channel below the completion line 16 to Figure 2 Holes are drilled at the bracket intervals and anchor bolts are installed (step S14).

[0076] Next, the operator places the threshold 1 and the bracket 2 as Figure 2 The object in the state after the assembly is sent into the lifting channel and temporarily fixed to the wall surface by anchor bolts (step S15). In addition, a hanging basket or a work platform that can be lifted and moved is provided in the lifting channel.

[0077] Then, if Figure 5 As shown, the operator uses the clamping member 8 to fix the adjustment mechanism 101 of the threshold positioning auxiliary device 100 to the opening side 7 (step S16). When setting 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 core 3 does not contact the support arm 102 of the adjustment mechanism 101. In addition, the support arm position adjustment knob 116 is loosened, and the support arm 102 is pulled out to the lifting channel side so that it does not interfere with the threshold 1.

[0078] Next, the operator loosens the bracket bolts 12 between the wall side bracket 2a and the door sill side bracket 2b to make the door sill 1 adjustable. Figure 5As shown in FIG. 1 , the door sill 1 is placed on the support arm 102 of the adjustment mechanism 101 (step S17). When placing, the door sill 1 is lifted while the support arm position adjustment knob 116 is loosened, and the support arm 102 pulled out to the lifting channel side is pushed in with the other hand to place the door sill 1 on the support arm 102. This operation is performed on the left and right adjustment mechanisms. After placing, the door sill 1 is temporarily fixed by being sandwiched between the support arm 102 and the door sill fixing fitting 155 by tightening the door sill fixing knob 157.

[0079] Next, the operator sets the operation controller 160 on the upper surface of the door sill 1 (step S18). The above completes the setting of the door sill positioning auxiliary device. Figure 5 The following is the equipment configuration shown. Next, we move on to the positioning operation of the threshold 1.

[0080] First, the front-rear tilt of the threshold 1 is adjusted to be horizontal (step S19). When adjusting the front-rear tilt, a level is placed on the upper surface of the threshold 1, and the angle is adjusted using the front-rear tilt adjustment screw 110 to make it horizontal while confirming the position of the bubble.

[0081] Next, the door sill positioning assisting device 100 is powered on, and the automatic leveling control mode is enabled to make the left and right inclinations (Roll axis) of the door sill level (step S20).

[0082] Next, the setting height of the threshold 1 is adjusted. The actuator of the right adjustment mechanism 101 is operated by operating 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 projected from the laser line marker 9 onto the height index scale 161 is at a distance H from the upper surface of the threshold. At this time, the threshold positioning auxiliary device 100 is in the automatic level control mode, so the height is adjusted while maintaining the horizontal state of the threshold 1. After the height of the threshold 1 is determined, the switch operation is used to maintain the command value, and the operation of the actuator 107 is stopped (step S21).

[0083] Next, the bracket bolts 12 between the wall bracket 2a and the door sill bracket 2b are temporarily tightened (step S22). The door sill 1 is adjusted in the front and rear directions (with the pitch axis) and in the left and right directions (with the roll axis) and in the height (with the Z axis).

[0084] Next, the bolts between the door sill 1 and the door sill side bracket 2b are loosened (step S23). Furthermore, the door sill fixing knob 157 is loosened to release the temporary fixing of the door sill 1. As a result, the door sill 1 is adjusted on the door sill side bracket 2b in the horizontal plane (X axis, Y axis, Yaw axis).

[0085] Afterwards, while aligning the position of the punched hole engraved on the side of the threshold 1 carried on the support arm 102 with the reference core 3, the distance between the reference core 3 and the threshold 1 is made consistent with the predetermined distance, thereby completing the positioning of the threshold 1 on the horizontal plane (step S24).

[0086] Next, in order to prevent the positioned door sill 1 from shifting, the door sill fixing knob 157 is tightened again to temporarily fix the door sill 1, and the bolts between the door sill 1 and the door sill side bracket 2b are temporarily tightened (step S25).

[0087] Next, a level is placed on the threshold 1 to confirm the position of the threshold 1, and the distance from the reference core 3 and the consistency with the completion line 16 are confirmed again by the height indicator scale 161 (step S26). After the confirmation is completed, the anchor bolts in the temporary tightening state, the bolts between the brackets, and the bolts between the threshold (sill) and the bracket are further tightened and fixed (step S27). The above completes the fixing operation of the threshold.

[0088] Finally, the door sill fixing knob 157 is loosened to release the fixing of the door sill 1 and the support arm 102, and the clamping member 8 is released while the support arm position adjustment knob 116 is loosened and the support arm 102 is pulled out to the lifting channel side, and the left and right adjustment devices 101 and the operation controller 160 of the door sill positioning auxiliary device 100 are removed (step S28). The above is a series of processes of the method for installing the door sill 1.

[0089] (Effect)

[0090] By filtering and averaging the information of the tilt sensor, the deviation of the tilt data with large deviation can be reduced, and it can be stably controlled to be horizontal. As a result, the tilt angle stably enters the predetermined range, so the power consumption of the microcomputer can be reduced by turning off the wireless function. In addition, by suppressing the power consumption of the microcomputer, the duration of the battery (power supply) can be extended. Furthermore, by extending the battery duration, the maintenance operation time such as battery replacement and charging can be shortened.

[0091] Furthermore, the operator who performs the door sill installation operation does not need to support the weight of the door sill 1 when adjusting the door sill 1. In addition, by using the door sill positioning auxiliary device 100 to adjust the position and posture of the door sill, which is difficult in the door sill installation operation, the inclination angle and position of the door sill 1 can be adjusted without hitting the door sill 1 with a hammer as in the past. As a result, the door sill installation operation can be facilitated and the operation time can be shortened compared with the past.

[0092] Moreover, since the operation controller 160 is configured to communicate wirelessly with the control device 113, there is no need for control cables, etc., and the area for operators to pass can be kept wider and safer by setting the position of the support arm as close to the opening side 7 as possible.

[0093] <Second Embodiment>

[0094] In the first embodiment, the control device 113 and the operation controller 160 are directly connected wirelessly, but as a second embodiment, for example, a wireless LAN access point connected to a server may be provided, 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 provided, the data of the inclination angle of the threshold 1 stored in the microcomputer 162, such as the posture information when the inclination angle enters a predetermined range, may be wirelessly transmitted to the access point, and the data during construction may be stored in the server. This may be used for evaluation of installation quality, etc.

[0095] <Modifications, etc.>

[0096] In addition, the present invention is not limited to the above-mentioned embodiments, and includes various modifications. For example, in the above-mentioned embodiments, the contents of the present invention are described in detail to facilitate understanding, but the present invention is not limited to having all the structures described in the above-mentioned embodiments. In addition, a part of the structure of a certain embodiment can be replaced with the structure of other embodiments. In addition, the structure of other embodiments can also be added to the structure of a certain embodiment. In addition, a part of the structure of each embodiment can also be deleted, or other structures can be added, or replaced with other structures.

[0097] In addition, part or all of the above-mentioned structures, functions, processing parts, processing units, etc. can also be implemented by hardware, such as by designing with integrated circuits. In addition, the above-mentioned structures, functions, etc. can also be implemented by software by interpreting and executing programs that implement each function through a processor. Information such as programs, tables, files, etc. that implement each function can be stored in a recording device such as a memory, a hard disk, an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, or a DVD.

[0098] In addition, the control lines and information lines are considered to be necessary for the description, and may not necessarily represent all the control lines and information lines in the product. In fact, it can be considered that almost all the structures are connected to each other.

[0099] For example, in the above embodiment, the electric actuator 107 is used in the height adjustment part 104 of the adjustment mechanism 101, but it can also be replaced with a manual operation, and the actuator 107 can also be configured as a sliding bracket 108 that moves up and down using a ball screw with an adjustment knob. In addition, the mechanism of the front and rear tilt adjustment screw 110 that is manually operated can also be motorized.
