[Operation and Action of Sliding Door Opening / Closing Device 1]
The operation and action of the sliding door opening / closing device 1 will be described with reference to FIG. FIG. 10 is an explanatory diagram illustrating a lock process in which the operation lever 17 is rotated from the release position to the lock position, and a release process in which the operation lever 17 is rotated from the lock position to the release position. In FIG. 10, the locking process is indicated by a dashed arrow, and the releasing process is indicated by a solid arrow. 10A to 10J show the contact of the operation lever 17, the coil spring 34, the spring mounting portion 94, the end portions 68 </ b> A and 68 </ b> B of the projection portion 68, and the notch groove portion 96 of the rotating body 30. A state in which the positions of the end portions 98 and 100 change is shown. For convenience of drawing, the reference numbers of the respective members are shown only in the state shown in FIG. 10A and the state shown in FIG. 10F, and the tubular portion 82 is substituted for the notch groove 96. Is illustrated.

(Operation of lock process)
The state shown in FIG. 10A shows a state where the operation lever 17 is located at a release position where the crescent 15 is separated from the crescent receiver 16. At the release position, the coil spring 34 is contracted to a state close to a natural state, and the end 68B of the protrusion 68 is in contact with the contact end 100 of the notch groove 96.

  When the operation lever 17 is rotated in the clockwise direction in FIG. 10, the protrusion 68 is rotated in accordance with the rotation operation of the operation lever 17. Since the end 68B of the protrusion 68 is in contact with the contact end 100, the rotating body 30 rotates with the rotation of the operation lever 17 and the protrusion 68 as shown in FIG. Moved. As the rotating body 30 rotates, the spring mounting portion 94 moves upward and gradually leaves the spring mounting pin 118. As the spring mounting portion 94 moves, the coil spring 34 gradually expands and accumulates elastic energy.

  As the rotating body 30 rotates, when the spring mounting portion 94 reaches the position farthest from the spring mounting pin 118 as shown in FIG. 10C, the coil spring 34 is in the most extended state. When the operation lever 17 is further rotated as shown in FIG. 10D, the spring mounting portion 94 starts to move downward as the rotating body 30 rotates. When the spring mounting portion 94 starts to move downward, the rotating body 30 is in a state in which it can rotate relative to the protrusion 68 of the operation portion 28.

  Since the coil spring 34 biases the spring mounting portion 94 downward by an elastic force, the downward movement of the spring mounting portion 94 is caused by the rotation operation of the operation lever 17 in accordance with the relative rotation of the rotary body 30. It is performed at a speed higher than the speed. In accordance with the relative rotation of the rotating body 30, the end 68B of the protrusion 68 is separated from the contact end 100 of the notch groove 96, while the end 68A of the protrusion 68 is shown in FIG. As shown in FIG. 4A, the abutting end portion 98 of the notch groove portion 96 abuts. Due to the relative rotation of the rotating body 30, the elastic energy of the coil spring 34 is rapidly released.

  When the rotating body 30 is relatively rotated, the gear 110 meshes with a large number of teeth 102 on the rotating body 30 and rotates at a high speed. Due to the high-speed rotation of the gear 110, the signal generator 32 can generate a relatively large electrical signal. The polarity of the electrical signal is a polarity corresponding to the rotating direction of the rotating body 30, for example, a positive polarity. The microcontroller 204, the comparator 206, and the wireless communication circuit 208 each operate using a relatively large electrical signal as a power supply voltage. The microcontroller 204 controls the wireless communication circuit 208 in accordance with the determination result from the comparator 206, and communicates a detection signal for detecting that the operation lever 17 is turned from the release position to the lock position to the external terminal device.

  When the end 68 </ b> A of the protrusion 68 contacts the contact end 98, the rotating body 30 is rotated clockwise together with the operation lever 17 and the protrusion 68 of the operation section 28 by the elastic force of the coil spring 34. It is rotated. FIG. 10F shows a state in which the operation lever 17 is turned to the lock position. In the locked position, the coil spring 34 is contracted to a state close to the natural state, and the end 68 </ b> A of the protrusion 68 is in contact with the contact end 98 of the notch groove 96.

(Operation of release process)
When the operation lever 17 is rotated counterclockwise from the lock position shown in FIG. 10F, the protrusion 68 is rotated in accordance with the rotation operation of the operation lever 17. Since the end 68A of the protrusion 68 is in contact with the contact end 98, the rotating body 30 rotates with the rotation of the operation lever 17 and the protrusion 68 as shown in FIG. Moved. As the rotating body 30 rotates, the spring mounting portion 94 moves upward and gradually leaves the spring mounting pin 118. As the spring mounting portion 94 moves, the coil spring 34 gradually expands and accumulates elastic energy.

  As the rotating body 30 rotates, when the spring mounting portion 94 reaches the position farthest from the spring mounting pin 118 as shown in FIG. 10H, the coil spring 34 is in the most extended state. When the operation lever 17 is further rotated as shown in FIG. 10I, the spring mounting portion 94 starts to move downward as the rotating body 30 rotates. When the spring mounting portion 94 starts to move downward, the rotating body 30 is in a state in which it can rotate relative to the protrusion 68 of the operation portion 28.

  Since the coil spring 34 biases the spring mounting portion 94 downward by an elastic force, the downward movement of the spring mounting portion 94 is caused by the rotation operation of the operation lever 17 in accordance with the relative rotation of the rotary body 30. It is performed at a speed higher than the speed. According to the relative rotation of the rotating body 30, the end 68A of the protrusion 68 is separated from the contact end 98 of the notch groove 96, while the end 68B of the protrusion 68 is As shown in FIG. 5A, the abutting end 100 of the notch groove 96 abuts. Due to the relative rotation of the rotating body 30, the elastic energy of the coil spring 34 is rapidly released.

  When the rotating body 30 is relatively rotated, the gear 110 meshes with a large number of teeth 102 on the rotating body 30 and rotates at a high speed. Due to the high-speed rotation of the gear 110, the signal generator 32 can generate a relatively large electrical signal. The polarity of the electrical signal is a polarity corresponding to the rotating direction of the rotating body 30, for example, a negative polarity. The microcontroller 204, the comparator 206, and the wireless communication circuit 208 each operate using a relatively large electrical signal as a power supply voltage. The microcontroller 204 controls the wireless communication circuit 208 in accordance with the determination result from the comparator 206, and communicates a detection signal for detecting that the operation lever 17 is turned from the lock position to the release position to the external terminal device.

  When the end 68B of the projection 68 abuts against the abutment end 100, the rotating body 30 moves in the counterclockwise direction together with the operation lever 17 and the projection 68 of the operation unit 28 by the elastic force of the coil spring 34. Is rotated. The operation lever 17 is turned to the release position shown in FIG.

In addition, no special operation other than the turning operation of the operation lever 17 is required to store elastic energy in the coil spring 34.

  In the present embodiment, the signal generator 32, the coil spring 34, and the circuit board 36 are accommodated in the housing body 22 so as to be arranged on the opposite sides with respect to the arrangement position of the rotating body 30. As a result, the size of the housing body 22 can be reduced in the direction in which the rotation axis of the rotating body 30 extends, and the housing body 22 protrudes from the sliding door cage such as the vertical rod 12 of the inner door 3. The amount can be reduced.

  In this embodiment, as shown in FIG. 10A, when the operation lever 17 is located at the release position, the contact end portion 100 of the notch groove portion 96 contacts the end portion 68B of the projection portion 68. Therefore, the elastic energy can be accumulated in the coil spring 34 from the time when the turning operation of the operation lever 17 is started from the release position. Further, as shown in FIG. 10F, when the operation lever 17 is positioned at the lock position, the contact end portion 98 of the notch groove portion 96 is in contact with the end portion 68A of the projection portion 68. The elastic energy can be accumulated in the coil spring 34 from the time when the turning operation of the operation lever 17 is started from the lock position.

  In the present embodiment, the notch groove portion 96 is formed in the cylindrical portion 82 formed to protrude from the left side surface of the rotating body 80, and the spring mounting portion 94 is disposed to protrude from the right side surface of the rotating body 80. The As a result, it is possible to prevent the protrusion 68 of the operation portion 28 and the upper mounting portion 114 of the coil spring 34 from interfering during the rotation of the rotating body 30.

  In the present embodiment, as shown in FIG. 7, the spring mounting hole 84 is disposed away from the center of the rotating body 398 in the radial direction from the notch groove portion 412, and is close to the outer peripheral portion of the rotating body 398. Arranged. As a result, as shown in FIGS. 10C and 10H, when the spring mounting portion 94 is farthest from the spring mounting pin 118, the length of extension of the coil spring 34 is made relatively large. The elastic energy stored in the coil spring 34 can be increased. For this reason, the signal generator 32 can generate a relatively large electrical signal.

[Operation and Action of Revolving Door Opening and Closing Device 300]
The operation and action of the rotary door opening / closing device 300 will be described with reference to FIG. FIG. 16 is an explanatory diagram showing a process in which the operation lever 306 is rotated in the arrow direction DS from the first rotation operation position where it is not operated to the second rotation operation position. 16A to 16E show the contact of the operation lever 306, the coil spring 370, the spring mounting portion 410, the end portions 396A and 396B of the projection portion 396, and the notch groove portion 412 of the rotating body 366. The state where each position with the edge parts 414 and 416 changes is shown. For convenience of drawing, the reference numbers of the respective members are shown only in the state shown in FIG. 16A and the state shown in FIG. 16E, and the tubular portion 400 is substituted for the notch groove portion 412. Is illustrated.

(Operation when the revolving door 302 is opened)
When the user does not operate the operation lever 306, the operation lever 306 is held at the first rotation operation position which is the rotation angle position shown in FIG. 16A by the elastic force of the return spring 322. In the first rotation operation position, the end 396B of the protrusion 396 is in contact with the contact end 416 of the notch groove 412 until the elastic force of the coil spring 370 balances with the elastic force of the return spring 322. The coil spring 370 is contracted.

  In order to open the revolving door 302, when the operation lever 306 is rotated in the arrow direction DS which is the clockwise direction in FIG. 16, the protrusion 396 is rotated in accordance with the rotation operation of the operation lever 306. Is done. Since the end 396B of the protrusion 396 is in contact with the contact end 416, the rotating body 366 rotates with the rotation of the operation lever 306 and the protrusion 396, as shown in FIG. Moved. As the rotating body 366 rotates, the spring mounting portion 410 moves upward and gradually leaves the spring mounting pin 434. Due to the movement of the spring mounting portion 410, the coil spring 370 gradually expands and accumulates elastic energy.

  As the rotating body 366 rotates, when the spring mounting portion 410 reaches the position farthest from the spring mounting pin 434 as shown in FIG. 16C, the coil spring 370 is in the most extended state. When the operating lever 306 is further rotated as shown in FIG. 16D, the spring mounting portion 410 starts to move downward as the rotating body 366 rotates. When the spring mounting portion 410 starts to move downward, the rotating body 366 can rotate relative to the protrusion 396 of the operation portion 364.

  Since the coil spring 370 biases the spring mounting portion 410 downward by an elastic force, the downward movement of the spring mounting portion 410 is caused by the rotation operation of the operation lever 306 according to the relative rotation of the rotating body 366. It is performed at a speed higher than the speed. In accordance with the relative rotation of the rotating body 366, the end 396B of the protrusion 396 is separated from the abutting end 416 of the notch groove 412, while the end 396A of the protrusion 396 is shown in FIG. As shown in FIG. 4A, the abutting end portion 414 of the notch groove portion 412 abuts. By the relative rotation of the rotating body 366, the elastic energy of the coil spring 370 is rapidly released.

  When the rotating body 366 is relatively rotated, the gear 426 meshes with the numerous teeth 418 on the rotating body 366 and rotates at a high speed. Due to the high-speed rotation of the gear 426, the signal generator 368 can generate a relatively large electrical signal. The polarity of the electrical signal is a polarity corresponding to the rotating direction of the rotating body 366, for example, a positive polarity. The microcontroller 204, the comparator 206, and the wireless communication circuit 208 each operate using a relatively large electrical signal as a power supply voltage. The microcontroller 204 controls the wireless communication circuit 208 according to the determination result from the comparator 206, and generates a detection signal for detecting that the operation lever 306 has been rotated from the first rotation operation position to the second rotation operation position. Communicate to an external terminal device.

  When the operation lever 306 is turned to the second turning operation position shown in FIG. 16E, the protruding piece 338 comes into contact with the forward turning restricting projection 328A and the protruding piece 340 is restricted from turning backward. It contacts the protrusion 330B. By these contact, the rotation operation position of the operation lever 306 in the arrow direction DS is regulated. By positioning the operation lever 306 at the second rotation operation position, the latch portion 314 can be retracted from the latch housing portion and the revolving door 302 can be opened. In the second rotation operation position shown in FIG. 16E, the coil spring 370 contracts from the most extended state shown in FIG.

(Operation when the revolving door 302 is closed)
In the second rotation operation position shown in FIG. 16E, when the rotation operation force is released from the operation lever 306, the operation lever 306 is moved by the elastic force of the return spring 322 larger than the coil spring 370. It is rotated in the direction opposite to the arrow direction DS from the second rotation operation position toward the first rotation operation position. In the present embodiment, immediately before the spring mounting portion 410 reaches the position farthest from the spring mounting pin 434 and the coil spring 370 reaches the most extended state, the rotating body 366 is moved in the direction of the arrow by the elastic force of the coil spring 370. The elastic force of the return spring 322 is larger than the force of rotating the rotating body 366 in the direction opposite to the arrow direction DS through the protrusion 396 by the elastic force of the return spring 322, rather than the force rotating the DS. The return spring 322 is configured so as to be larger than the elastic force of the coil spring 370 when the coil spring 370 is most extended.

  In accordance with the return rotation of the operation lever 306, the protrusion 396 rotates the rotating body 366 in the direction opposite to the arrow direction DS in a state of being in contact with the contact end 414. When the spring mounting portion 410 reaches a position farthest from the spring mounting pin 434, the coil spring 370 is in the most extended state. The coil spring 370 accumulates elastic energy from the contracted state shown in FIG. 16E until it reaches the most extended state.

  When the operation lever 306 is further returned and rotated from the state in which the coil spring 370 is most extended, the coil spring 370 biases the spring mounting portion 410 downward by an elastic force. This movement is performed at a speed higher than the speed of the rotation operation of the operation lever 306 according to the relative rotation of the rotating body 366. In accordance with the relative rotation of the rotating body 366, the end 396A of the protrusion 396 is separated from the contact end 414 of the notch groove 412 while the end 396B of the protrusion 396 is separated from the notch groove 412. It abuts against the abutting end 416. By the relative rotation of the rotating body 366, the elastic energy of the coil spring 370 is rapidly released.

  When the rotating body 366 is relatively rotated, the gear 426 meshes with the numerous teeth 418 on the rotating body 366 and rotates at a high speed. Due to the high-speed rotation of the gear 426, the signal generator 368 can generate a relatively large electrical signal. The polarity of the electrical signal is a polarity corresponding to the rotating direction of the rotating body 366, for example, a negative polarity. The microcontroller 204, the comparator 206, and the wireless communication circuit 208 each operate using a relatively large electrical signal as a power supply voltage. The microcontroller 204 controls the wireless communication circuit 208 in accordance with the determination result from the comparator 206, and generates a detection signal for detecting that the operation lever 306 has been rotated from the second rotation operation position to the first rotation operation position. Communicate to an external terminal device.

  When the operation lever 306 is rotated to the first rotation operation position shown in FIG. 16A, the latch portion 314 enters the inside of the latch housing portion, and the rotary door 302 can be closed.

[Effects of Second Embodiment]
When a user locks the door and goes out, when someone turns the operating levers 304 and 307, or when an elderly person goes out without permission, the operating levers 304 and 306 are turned. When operated, the door signal generation device 360 of the present embodiment can communicate a detection signal representing the turning operation of the operation levers 304 and 306 to the external terminal device.

  Even when the operation levers 304 and 306 are rotated slowly, the door signal generation device 360 of the present embodiment generates a relatively large electric signal in the signal generation unit 368 by the action of the coil spring 370. be able to. In addition, no special operation other than the rotation operation of the operation levers 304 and 306 is required in order to accumulate elastic energy in the coil spring 370.

  In the present embodiment, the signal generation unit 368, the coil spring 370, and the circuit board 372 are accommodated in the housing body 362 so as to be arranged on the opposite sides with respect to the arrangement position of the rotating body 366. As a result, the size of the housing body 362 can be reduced in the direction in which the rotation axis of the rotating body 366 extends, and the door signal generator 360 can be easily incorporated into the rotating door 302.

  In this embodiment, as shown in FIG. 16A, when the operation lever 306 is located at the first rotation operation position, the contact end 416 of the notch groove 412 is the end 396B of the projection 396. Therefore, the elastic energy can be accumulated in the coil spring 370 from the time when the rotation operation of the operation lever 306 is started from the first rotation operation position. Further, as shown in FIG. 16E, when the operation lever 306 is located at the second rotation operation position, the contact end 414 of the notch groove 412 contacts the end 396A of the projection 396. Therefore, the elastic energy can be accumulated in the coil spring 370 from the time when the rotation operation of the operation lever 306 is started from the second rotation operation position.

  In this embodiment, the notch groove portion 412 is formed in the cylindrical portion 400 formed to protrude from the left side surface of the rotating body 398, and the spring mounting portion 410 is disposed to protrude from the right side surface of the rotating body 398. The As a result, it is possible to prevent the protrusion 396 of the operation portion 364 and the upper mounting portion 430 of the coil spring 370 from interfering during the rotation of the rotating body 366.

  In the present embodiment, as shown in FIG. 13, the spring mounting portion 410 fixed to the spring mounting hole is disposed away from the center of the rotation main body 398 in the radial direction from the notch groove portion 412, and the rotation main body. 398 is disposed close to the outer peripheral portion. As a result, as shown in FIG. 16C, the length of extension of the coil spring 370 when the spring mounting portion 410 is farthest from the spring mounting pin 434 can be made relatively large. The accumulated elastic energy can be increased. For this reason, the signal generator 368 can generate a relatively large electrical signal.

<Third Embodiment>

And the elastic energy of the coil spring is released. When the elastic energy is released, the operation lever 534 stops in a posture in which the distal end portion of the operation lever 534 faces rearward as shown in FIG.

  When the drawer 502 is further pushed rearward, the distal end portion of the operation lever 534 presses the operation engagement portion 522A downward, and the operation leaf spring 522 is elastically deformed. Due to this elastic deformation, the actuating leaf spring 522 passes below the tip portion of the actuating lever 534 and moves rearward from the tip portion of the actuating lever 534 as shown in FIG.

  When the actuating lever 534 is pushed from the opened state shown in FIG. 18 to the closed state shown in FIG. 17, the microcontroller of the signal generator 530 for pulling out controls the wireless communication circuit to A detection signal indicating that the drawer 502 is closed is communicated to the external terminal device.
