<< Electrical configuration of signal generator 20 for door >>
The electrical configuration of the door signal generator 20 will be briefly described. The door signal generator 20 includes a control circuit that receives an electric signal generated by the generator 182 as driving power. The control circuit is modularized and mounted on a circuit board 34, and mainly includes a microcontroller, a wireless communication circuit, and an antenna as electrical components. This modularized control circuit is embodied in "radio transmitter module PTM430J" manufactured by EnOcean (registered trademark) GmbH.

When the operating levers 12 and 22 are rotated and the generator 182 generates an electric signal, the wireless communication circuit 208 generates a communication signal indicating that the operating lever has been rotated, and the antenna generates a communication signal. Communicate with an external terminal device (not shown). As the external terminal device, a mobile terminal device such as a smartphone, a personal computer, or the like is used.

<Operation and operation of rotary door opening / closing device 1>
The operation and operation of the rotary door opening / closing device 1 will be described mainly with reference to FIG. FIG. 14 shows the processes (A), (B1) to (D1) in which the operating lever 22 is rotated in the clockwise direction CW1 from the non-rotating operating position that is not operated to the first rotating operating position. It is explanatory drawing which shows the process (A), (B2) to (D2) which the rotation operation is performed in the counterclockwise direction CW2 from the rotation operation position to the second rotation operation position. FIG. 14 schematically shows members such as an operating lever 22, a cam member 28, a coil spring 178, a pinion 220, and a rack 236, and shows a state in which each position of each member changes. For convenience of drawing, the operating lever 22, coil spring 178, pinion 220, and rack 236 differ in shape and placement from those shown in the other drawings, but the functions of the members are the same. For example, as shown in FIG. 3, the operating lever 22 is arranged so as to extend to the right side where the moving member 180 is arranged with respect to the rotating axis AX of the rotating shaft member 26. However, for convenience of drawing, in FIG. 14, the operating lever 22 is arranged so as to extend to the left side, which is the side opposite to the side where the moving member 180 including the rack 236 is arranged.

(Operation when the operation lever 22 is rotated in the clockwise direction CW1)
When the user does not operate the operating lever 22, the operating lever 22 is held at the non-rotating operating position, which is the rotational angle position shown in FIG. 14A, by the elastic force of the torsion coil spring 128. In the non-rotating operation position, as shown in FIG. 10, both extending portions 152 and 154 of the torsion coil spring 128 are connected to both pins 122 and 124 protruding from the pin support pedestals 110 and 112 of the device housing 24 from below. Each abuts. The operating lever 22 is constantly urged to return to the non-rotating operating position by the elastic force of the torsion coil spring 128. Further, in the non-rotating operation position, the large-diameter pin portion 246 of the cam engaging pin 242 attached to the moving member 180 is a cam member due to the elastic force of the coil spring 178 as shown in FIG. 14 (A). Engage with the reference position groove 86 of 28.

When the operating lever 22 is rotated in the clockwise direction CW1 in FIG. 14 to open and close the rotary door 10, the rotating operating member 126 shown in FIG. 10 is accompanied by the rotating operation of the operating lever 22. Rotates in the clockwise direction in FIG. 10 together with the cam member 28. Due to the rotation of the rotation actuating member 126, the spring engaging end portion 146 of the rotation actuating member 126 presses the extending portion 152 of the torsion coil spring 128 downward against the elastic force of the torsion coil spring 128. However, it rotates clockwise. Due to the rotation of the cam member 28, the large-diameter pin portion 246 of the cam engaging pin 242 resists the elastic force of the coil spring 178 and the reference position groove portion of the cam member 28, as shown in FIG. 14 (B1). It moves from 86 along the first lower cam surface 74. The large diameter pin portion 246 moves linearly with respect to the rotation axis AX. With the movement of the large-diameter pin portion 246, the coil spring 178 accumulates elastic energy.

When the operation lever 22 is further rotated in the clockwise direction CW1 in FIG. 14, the upper regulation arm portion 136 and the lower regulation arm portion 138 of the rotation actuating member 126 are subjected to the rotation regulation collision of the device housing 24. It comes into contact with the regulated ends 114A and 116B of the portions 114 and 116, respectively. By this contact, the maximum rotation angle at which the operating lever 22 and the cam member 28 rotate in the clockwise direction in FIG. 10 is regulated. When the operating lever 22 is rotated clockwise to the maximum rotation angle, the large-diameter pin portion 246 of the cam engaging pin 242 has an elastic force of the coil spring 178 as shown in FIG. 14 (C1). The cam member 28 moves from the first lower cam surface 74 to the first lower connecting portion 78.

When the large-diameter pin portion 246 of the cam engaging pin 242 reaches the first lower connecting portion 78, the large-diameter pin portion 246 is seconded by the elastic force of the coil spring 178 as shown in FIG. 14 (D1). It moves toward the second lower connecting portion 80 while engaging with the lower cam surface 76. When the large diameter pin portion 246 moves toward the second lower connecting portion 80, the coil spring 178 releases the accumulated elastic energy. The rotation position of the operation lever 22 shown in FIGS. 14 (C1) and 14 (D1) is the first rotation operation position in which the operation lever 22 is rotated by the maximum rotation angle in the clockwise direction CW1.

By releasing the elastic energy of the coil spring 178, the generator 182 generates an electric signal and supplies it to the control circuit of the circuit board 34. The control circuit operates using the supplied electric signal as driving power, and detects that the operation lever 22 has been rotated from the non-rotation operation position to the first rotation operation position through the wireless communication circuit. Communicate the detection signal to the external terminal device.

In the state shown in FIG. 14 (D1), when the user releases the rotation operation of the operating lever 22, the rotation operating member 126 and the cam member 28 are counterclockwise in FIG. 10 due to the elastic force of the torsion coil spring 128. Rotate clockwise. When the extending portion 152 of the torsion coil spring 128 abuts on the pin 122 protruding from the pin support pedestal 110 from below, the rotation actuating member 126 and the cam member 28 stop rotating and are shown in FIG. It is held in the indicated rotation position.

When the cam member 28 returns from the first rotation operation position shown in FIG. 14 (D1) to the non-rotation operation position shown in FIG. 14 (A), the large-diameter pin portion 246 of the cam engagement pin 242 becomes , Engage with the second lower connecting portion 80 and move to the reference position groove portion 86. Specifically, in FIG. 7, the large-diameter pin portion 246 first moves while engaging with the downwardly inclined connecting portion 82. After that, the large-diameter pin portion 246 passes through the lower step portion 84 and moves to the reference position groove portion 86. When the large-diameter pin portion 246 moves while engaging with the downwardly inclined connecting portion 82, the large-diameter pin portion 246 moves while retracting inside the moving member 180 against the elastic force of the coil spring 244. ..

(Operation when the operation lever 22 is rotated in the counterclockwise direction CW2)
When the user does not operate the operating lever 22, the operating lever 22 is held at the non-rotating operating position, which is the rotational angle position shown in FIG. 14A, by the elastic force of the torsion coil spring 128. Further, in the non-rotating operation position, the large-diameter pin portion 246 of the cam engaging pin 242 attached to the moving member 180 is a cam member due to the elastic force of the coil spring 178 as shown in FIG. 14 (A). Engage with the reference position groove 86 of 28.

When the operating lever 22 is rotated in the counterclockwise direction CW2 in FIG. 14 to open and close the rotary door 10, the rotating operating member shown in FIG. 10 is accompanied by the rotating operation of the operating lever 22. 126, together with the cam member 28, rotates counterclockwise in FIG. Due to the rotation of the rotation actuating member 126, the spring engaging end portion 148 of the rotation actuating member 126 presses the extending portion 154 of the torsion coil spring 128 downward against the elastic force of the torsion coil spring 128. However, it rotates counterclockwise. Due to the rotation of the cam member 28, the large-diameter pin portion 246 of the cam engaging pin 242 resists the elastic force of the coil spring 178 and the reference position groove portion of the cam member 28, as shown in FIG. 14 (B2). It moves from 86 along the first upper cam surface 62. The large diameter pin portion 246 moves linearly with respect to the rotation axis AX. With the movement of the large-diameter pin portion 246, the coil spring 178 accumulates elastic energy.

When the operating lever 22 is further rotated in the counterclockwise direction CW2 in FIG. 14, the upper regulating arm portion 136 and the lower regulating arm portion 138 of the rotation operating member 126 restrict the rotation of the device housing 24. It abuts on the regulated ends 114B and 116A of the protrusions 114 and 116, respectively. This contact regulates the maximum rotation angle at which the operating lever 22 and the cam member 28 rotate in the counterclockwise direction in FIG. When the operating lever 22 is rotated counterclockwise to the maximum rotation angle, the large diameter pin portion 246 of the cam engaging pin 242 becomes elastic of the coil spring 178 as shown in FIG. 14 (C2). It moves from the first upper cam surface 62 of the cam member 28 to the first upper connecting portion 66 against the force.

When the large-diameter pin portion 246 of the cam engaging pin 242 reaches the first upper connecting portion 66, the large-diameter pin portion 246 becomes the second due to the elastic force of the coil spring 178 as shown in FIG. 14 (D2). It moves toward the second upper connecting portion 68 while engaging with the upper cam surface 64. When the large diameter pin portion 246 moves toward the second upper connecting portion 68, the coil spring 178 releases the accumulated elastic energy. The rotation position of the operation lever 22 shown in FIGS. 14 (C2) and (D2) is the second rotation operation position in which the operation lever 22 is rotated by the maximum rotation angle in the counterclockwise direction CW2.

By releasing the elastic energy of the coil spring 178, the generator 182 generates an electric signal and supplies it to the control circuit of the circuit board 34. The control circuit operates using the supplied electric signal as driving power, and detects that the operation lever 22 has been rotated from the non-rotation operation position to the second rotation operation position through the wireless communication circuit. Communicate the detection signal to the external terminal device.

In the state shown in FIG. 14 (D2), when the user releases the rotation operation of the operating lever 22, the rotation operating member 126 and the cam member 28 are affected by the elastic force of the torsion coil spring 128, and the clock in FIG. It rotates in the clockwise direction. When the extending portion 154 of the torsion coil spring 128 abuts on the pin 124 protruding from the pin support pedestal 112 from below, the rotation actuating member 126 and the cam member 28 stop rotating and are shown in FIG. It is held in the indicated rotation position.

When the cam member 28 returns from the second rotation operation position shown in FIG. 14 (D2) to the non-rotation operation position shown in FIG. 14 (A), the large-diameter pin portion 246 of the cam engagement pin 242 becomes , Engage with the second upper connecting portion 68 and move to the reference position groove portion 86. Specifically, in FIG. 7, the large-diameter pin portion 246 first moves while engaging with the upwardly inclined connecting portion 70. After that, the large-diameter pin portion 246 passes through the lower step portion 72 and moves to the reference position groove portion 86. When the large-diameter pin portion 246 moves while engaging with the upwardly inclined connecting portion 70, the large-diameter pin portion 246 moves while retracting inside the moving member 180 against the elastic force of the coil spring 244. ..

<Effect of embodiment>
When someone rotates the operation levers 12 and 22 while the user locks the door and goes out, or when the elderly person goes out without permission, the operation levers 12 and 22 are rotated. When operated, the door signal generator 20 of the present embodiment can communicate the rotation operation detection signal representing the rotation operation of the operation levers 12 and 22 to the external terminal device.

Even when the operating levers 12 and 22 are rotated slowly, the door signal generator 20 of the present embodiment generates a relatively large electric signal in the generator 182 by the action of the coil spring 178. Can be done. Moreover, in order to store elastic energy in the coil spring 178, no special operation other than the rotation operation of the operation levers 12 and 22 is required.

Since the moving member 180 is arranged so as to linearly move toward the rotating axis AX of the rotating shaft member 26 to which the cam member 28 is attached, the moving direction of the moving member 180 is separated from the rotating axis AX. The moving stroke of the moving member 180 can be lengthened as compared with the arrangement configuration. By lengthening this movement stroke, the generator 182 can generate a relatively large electric signal.

The cam member 28 is a first lower cam surface 74 and a first lower cam surface 74 used when the operation lever 22 rotates clockwise CW1 as a cam surface on which the large-diameter pin portion 246 of the cam engagement pin 242 engages. 2 It has a lower cam surface 76, a first upper cam surface 62 used when the operating lever 22 rotates in the counterclockwise direction CW2, and a second lower cam surface 64. As a result, the generator 182 can generate an electric signal even when the operating lever 22 is rotated in either the forward or reverse direction. Moreover, since the moving member 180 moves in the same direction even when the operating lever 22 is rotated in either the forward or reverse direction, the generator 182 can generate an electric signal having a constant polarity, and the circuit. The control circuit of the substrate 34 does not need to include a rectifier circuit.

The cam member 28 has an upper step portion 72, a lower step portion 74, and a reference position groove portion 86. The reference position groove portion 86 is formed in the vicinity of both the step portions 72 and 74. As a result, when the cam member 28 rotates, in both step portions 72 and 74, the large diameter pin portion 246 of the cam engaging pin 242 is connected to the reference position groove portion 86 to the second upper connecting portion 68 and the second lower connecting portion. Since the movement toward the 80 is restricted, the large-diameter pin portion 246 is the first upper cam surface 62 or the first lower cam surface 74 from the reference position groove portion 86 according to the rotation direction of the cam member 28. Can be reliably moved towards.

Since the operation lever 22 and the cam member 28 are attached to the common rotation shaft member 26, the cam member 28 as large as possible is arranged inside the accommodation space SP1 having a limited size of the device housing 24. can do. Since the cam member 28 is large, a relatively gentle cam surface can be formed, and the frictional resistance between the large diameter pin portion 246 of the cam engaging pin 242 and the cam surface can be reduced.

In the non-rotating operating position, the tip of the operating lever 22 extends to the right from the rotating shaft member 26. As shown in FIG. 3, the device housing 24 is formed long in the right direction in which the tip end portion of the operating lever 22 extends. The power generation operation unit 32 is arranged in the accommodation space SP1 of the apparatus housing 24 in the accommodation space existing on the right side of the rotation shaft member 26. As a result, the accommodation space SP1 of the device housing 24 does not expand significantly in a direction different from the direction in which the tip end portion of the operating lever 22 extends, so that the door signal generator 20 can be compactly configured. Further, since the moving member 180 is arranged so as to move in the left-right direction in which the tip end portion of the operating lever 22 extends in the non-rotating operation position, in the accommodation space SP1 having a limited size of the device housing 24, The door signal generator 20 can be compactly configured while ensuring a long moving stroke of the moving member 180.

In addition, it is possible to smoothly perform linear motion in the left-right direction without fluctuating in the front-back direction.

The generator 182 is accommodated in the lower accommodating recess 190 of the base support member 170 so that the rotating shaft 182A is parallel to the vertical direction, which is a direction on a plane perpendicular to the horizontal direction in which the moving member 180 moves. Will be done. The plane perpendicular to the left-right direction, which is the direction in which the moving member 180 moves, is a plane parallel to the front and rear door surfaces of the rotary door 10. As a result, as compared with the configuration in which the rotating shaft 182A of the generator 182 is arranged in the direction perpendicular to the door surface, the device housing 24 does not protrude in the direction perpendicular to the door surface and is in the direction parallel to the door surface. A relatively long generator can be accommodated, and a relatively large electric signal can be generated in the generator while the door signal generator 20 is compactly configured.

As shown in FIGS. 3 and 8, the device housing 24 is opened to the rear side, which is the side facing the door surface of the rotary door 10, and the cam member 28 and the power generation operating unit 32 are devices from the rear side. It is assembled to the housing 24, and the circuit board 34 is also mounted on the device housing 24 from the rear side. As a result, the cam member 28, the power generation operation unit 32, the circuit board 34, and the like can be easily assembled, and the maintenance and inspection of these parts can be facilitated.
