[Operation and Action of the Sliding Door Opener 1]
The operation and action of the sliding door opening and closing device 1 will be described with reference to FIG. FIG. 10 is an explanatory view showing a lock process in which the operation lever 17 is turned from the release position to the lock position, and a release process in which the operation lever 17 is turned from the lock position to the release position. In FIG. 10, the locking process is indicated by a dashed arrow, and the unlocking process is indicated by a solid arrow. FIGS. 10A to 10J show the abutting of the operating lever 17, the coil spring 34, the spring mounting portion 94, the ends 68A and 68B of the protrusion 68, and the notch groove 96 of the rotating body 30. The state where each position with the end parts 98 and 100 changes is shown. For convenience of description in the drawings, 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 cylindrical portion 82 is used instead of the cutout groove 96. Is illustrated.

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

  When the operation lever 17 is rotated clockwise in FIG. 10, the projection 68 is rotated with the rotation of the operation lever 17. Since the end 68 </ b> B of the projection 68 is in contact with the contact end 100, the rotating body 30 rotates together with the rotation of the operation lever 17 and the projection 68 as shown in FIG. Be moved. As the rotating body 30 rotates, the spring mounting portion 94 moves upward and gradually separates from the spring mounting pin 118. Due to the movement of the spring mounting portion 94, the coil spring 34 gradually expands and accumulates elastic energy.

  When the spring mounting portion 94 reaches a position farthest from the spring mounting pin 118 as shown in FIG. 10C in accordance with the rotation of the rotating body 30, the coil spring 34 is in the most expanded state. When the operation lever 17 is further rotated as shown in FIG. 10D, the spring mounting portion 94 starts moving downward according to the rotation of the rotating body 30. At the time when the spring mounting portion 94 starts to move downward, the rotating body 30 is in a state where it can be relatively rotated with respect to the projection 68 of the operation portion 28.

  Since the coil spring 34 urges the spring mounting portion 94 downward by the elastic force, the downward movement of the spring mounting portion 94 depends on the relative rotation of the rotating body 30 and the rotation of the operation lever 17. It is performed at a higher speed than the speed. According to the relative rotation of the rotating body 30, the end 68B of the projection 68 is separated from the contact end 100 of the notch groove 96, while the end 68A of the projection 68 is positioned at (E) in FIG. As shown in ()), it comes into contact with the contact end 98 of the notch groove 96. 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 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 electric signal. The polarity of the electric 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 operate using relatively large electric signals as power supply voltages. The microcontroller 204 controls the wireless communication circuit 208 according to the determination result from the comparator 206 and communicates a detection signal for detecting that the operation lever 17 has been turned from the release position to the lock position to the external terminal device.

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

(Operation in the release process)
When the operation lever 17 is rotated counterclockwise from the lock position shown in FIG. 10F, the projection 68 is rotated with the rotation 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 as the operation lever 17 and the protrusion 68 rotate, as shown in FIG. Be moved. As the rotating body 30 rotates, the spring mounting portion 94 moves upward and gradually separates from the spring mounting pin 118. Due to the movement of the spring mounting portion 94, the coil spring 34 gradually expands and accumulates elastic energy.

  When the spring mounting portion 94 reaches the position farthest from the spring mounting pin 118 as shown in FIG. 10H in accordance with the rotation of the rotating body 30, the coil spring 34 is in the most extended state. When the operation lever 17 is further rotated as shown in FIG. 10 (I), the spring mounting portion 94 starts moving downward according to the rotation of the rotating body 30. At the time when the spring mounting portion 94 starts to move downward, the rotating body 30 is in a state where it can be relatively rotated with respect to the projection 68 of the operation portion 28.

  Since the coil spring 34 urges the spring mounting portion 94 downward by the elastic force, the downward movement of the spring mounting portion 94 depends on the relative rotation of the rotating body 30 and the rotation of the operation lever 17. It is performed at a higher speed than the speed. According to the relative rotation of the rotating body 30, the end 68A of the projection 68 is separated from the contact end 98 of the notch groove 96, while the end 68B of the projection 68 is moved to the position (J in FIG. 10). As shown in ()), the notch groove 96 comes into contact with the contact end portion 100. 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 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 electric signal. The polarity of the electric 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 operate using relatively large electric signals as power supply voltages. The microcontroller 204 controls the wireless communication circuit 208 according to the determination result from the comparator 206, and communicates a detection signal for detecting that the operation lever 17 has been turned from the lock position to the release position to the external terminal device.

  When the end 68 </ b> B of the protrusion 68 contacts the contact end 100, the rotating body 30 moves in the counterclockwise direction together with the operation lever 17 and the protrusion 68 of the operation unit 28 by the elastic force of the coil spring 34. Is rotated. The operation lever 17 is rotated to the release position shown in FIG.

The door signal generation device 20 of the present embodiment can communicate a detection signal indicating a rotation operation of the operation lever 17 to an external terminal device.

  Even when the operation of rotating the operation lever 17 is performed slowly, the door signal generator 20 of the present embodiment can generate a relatively large electric signal in the signal generator 32 by the action of the coil spring 34. it can. In addition, no special operation other than the turning operation of the operation lever 17 is required to store the elastic energy in the coil spring 34.

  In the present embodiment, the signal generating unit 32, the coil spring 34, and the circuit board 36 are housed in the housing body 22 so as to be arranged on opposite sides with respect to the arrangement position of the rotating body 30. As a result, the dimension 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 a sliding door frame such as the vertical frame 12 of the inner door 3. The amount can be reduced.

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

  In the present embodiment, the notch groove portion 96 is formed in the cylindrical portion 82 formed so as to protrude from the left side surface of the rotating main body 80, and the spring mounting portion 94 is arranged so as to protrude from the right side surface of the rotating main body 80. You. As a result, it is possible to prevent the protrusion 68 of the operation unit 28 and the upper mounting portion 114 of the coil spring 34 from interfering with each other while the rotating body 30 is rotating.

  In this embodiment, as shown in FIG. 7, the spring mounting hole 84 is disposed radially away from the notch groove 412 from the center of the rotating main body 398, and close to the outer peripheral portion of the rotating main body 398. Placed. 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. Therefore, the elastic energy stored in the coil spring 34 can be increased. For this reason, the signal generator 32 can generate a relatively large electric signal.

[Operation and Function of Revolving Door Opening and Closing Device 300]
The operation and action of the revolving door opening and 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 non-operated first rotation operation position to the second rotation operation position. FIGS. 16A to 16E show abutment of the operating lever 306, the coil spring 370, the spring mounting portion 410, the ends 396A and 396B of the protrusion 396, and the notch groove 412 of the rotating body 366. The state where each position with the ends 414 and 416 changes is shown. For convenience of description in the drawings, the reference numbers of each member are shown only in the state shown in FIG. 16A and the state shown in FIG. 16E, and the cylindrical portion 400 is replaced with the cutout groove 412. Is illustrated.

(Operation when opening the revolving door 302)
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. In the first rotation operation position, the end 396 </ b> B of the protrusion 396 is in contact with the contact end 416 of the notch groove 412, and until the elastic force of the coil spring 370 balances the elastic force of the return spring 322. The coil spring 370 is contracted.

  When the operation lever 306 is rotated in the clockwise direction DS in FIG. 16 to open the revolving door 302, the projection 396 is rotated with the rotation 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 as the operation lever 306 and the protrusion 396 rotate, as shown in FIG. Be moved. As the rotating body 366 rotates, the spring mounting portion 410 moves upward and gradually separates from the spring mounting pin 434. The movement of the spring mounting portion 410 causes the coil spring 370 to gradually expand and store elastic energy.

  When the spring mounting portion 410 reaches a position farthest from the spring mounting pin 434 as shown in FIG. 16C in accordance with the rotation of the rotating body 366, the coil spring 370 becomes the most extended state. When the operation lever 306 is further rotated as shown in FIG. 16D, the spring mounting portion 410 starts moving downward according to the rotation of the rotating body 366. At the point in time when the spring mounting portion 410 starts moving downward, the rotating body 366 can rotate relative to the protrusion 396 of the operation portion 364.

  Since the coil spring 370 urges the spring mounting portion 410 downward by an elastic force, the downward movement of the spring mounting portion 410 depends on the relative rotation of the rotating body 366 and the rotation of the operation lever 306. It is performed at a higher speed 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 contact end 416 of the notch groove 412, while the end 396A of the protrusion 396 is positioned at (E) in FIG. As shown in (), the contact ends come into contact with the contact ends 414 of the notch grooves 412. Due to 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 a number of teeth 418 on the rotating body 366 and rotates at high speed. The high-speed rotation of the gear 426 allows the signal generator 368 to generate a relatively large electric signal. The polarity of the electric 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 operate using relatively large electric signals as power supply voltages. The microcontroller 204 controls the wireless communication circuit 208 according to the determination result from the comparator 206, and outputs a detection signal for detecting that the operation lever 306 has been turned from the first turning operation position to the second turning operation position. Communicate to an external terminal device.

  When the operation lever 306 is rotated to the second rotation operation position shown in FIG. 16E, the protruding piece 338 comes into contact with the front rotation restricting projection 328A, and the protruding piece 340 restricts the rear rotation. It contacts the projection 330B. By these abutments, the rotational 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 is retracted from the latch housing portion, and the rotating door 302 can be opened. In the second rotation operation position shown in FIG. 16E, the coil spring 370 has contracted from the most extended state shown in FIG. 16C.

(Operation when closing the revolving door 302)
When the rotation operation force is released from the operation lever 306 in the second rotation operation position shown in FIG. 16E, the operation lever 306 is moved to the second rotation operation position by the elastic force of the return spring 322 larger than the coil spring 370. It turns in the direction opposite to the arrow direction DS from the two turning operation position to the first turning 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 is in the most extended state, the resilient force of the coil spring 370 causes the rotating body 366 to move in the direction of the arrow. The elastic force of the return spring 322 is set such that the elastic force of the return spring 322 causes the force of rotating the rotating body 366 in the direction opposite to the arrow direction DS to be greater than the force of rotating the return spring 322 through the protrusion 396. The return spring 322 is configured to be larger than the elastic force of the coil spring 370 when the coil spring 370 is in the most extended state.

  In accordance with the return rotation of the operation lever 306, the protrusion 396 rotates the rotating body 366 in a 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 becomes the most expanded state. The coil spring 370 stores elastic energy from the contracted state shown in FIG. 16E to the most extended state.

  When the operating lever 306 is further returned and rotated from the state where the coil spring 370 is most extended, the coil spring 370 urges the spring mounting portion 410 downward by an elastic force. 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. According to the relative rotation of the rotating body 366, the end 396A of the protrusion 396 is separated from the abutting end 414 of the notch groove 412, while the end 396B of the protrusion 396 is connected to the notch groove 412. It contacts the contact end 416. Due to 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 a number of teeth 418 on the rotating body 366 and rotates at high speed. The high-speed rotation of the gear 426 allows the signal generator 368 to generate a relatively large electric signal. The polarity of the electric 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 operate using relatively large electric signals as power supply voltages. The microcontroller 204 controls the wireless communication circuit 208 according to the determination result from the comparator 206, and outputs a detection signal for detecting that the operation lever 306 has been turned from the second turning operation position to the first turning operation position. Communicate to an external terminal device.

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

[Effect of Second Embodiment]
The user turns the operation levers 304 and 307 while the door is locked and goes out, or the elderly people turn the operation levers 304 and 306 to go out without permission. When operated, the door signal generation device 360 of the present embodiment can communicate a detection signal indicating a rotation operation of the operation levers 304 and 306 to an external terminal device.

  Even when the operation of operating the levers 304 and 306 is performed slowly, the door signal generator 360 of the present embodiment generates a relatively large electric signal to the signal generator 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 to store the elastic energy in the coil spring 370.

  In the present embodiment, the signal generator 368, the coil spring 370, and the circuit board 372 are housed in the housing body 362 so as to be arranged on 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 rotation body 366 extends, and the door signal generator 360 can be easily incorporated into the rotation door 302.

  In the present 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 moved to the end 396B of the projection 396. , 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. 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 protrusion 396. Therefore, 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 the present embodiment, the notch groove portion 412 is formed on the cylindrical portion 400 formed so as to protrude from the left side surface of the rotating main body 398, and the spring mounting portion 410 is arranged so as to protrude from the right side surface of the rotating main body 398. You. As a result, it is possible to prevent the protrusion 396 of the operation unit 364 and the upper attachment 430 of the coil spring 370 from interfering with each other while the rotating body 366 is rotating.

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

The right guide mechanism 518 is mounted on the left side of the right support 514 and guides the right rail 514 in the front-rear direction. A left guide mechanism 520 is mounted on the right side of the left support 516 and guides the left rail in the front-rear direction.

  An operation leaf spring 522 is fixed close to a connection portion between the left side plate portion 508 and the back plate portion 510. The operation leaf spring 522 has an operation engagement portion 522A. The operation engagement portion 522A is formed by bending a central portion of the operation leaf spring 522 to project upward. When the operation engagement portion 522A is pressed from above, the operation leaf spring 522 is elastically deformed, and the operation engagement portion 522A is displaced downward. The operating leaf spring 522 moves in the front-rear direction with the opening and closing movement of the drawer 502 in the front-rear direction.

  The left support 516 includes a mounting pedestal 524. The mounting pedestal 524 is disposed near the left side plate 508 and has a mounting plane extending in the front-rear direction. The pullout signal generator 530 is mounted on a mounting plane of the mounting base 524 by a pair of mounting screws 532A and 532B.

(When the drawer 502 can be opened)
When the drawer 502 is in the closed state, the operating lever 534 is positioned with the tip of the operating lever 534 facing rearward as shown in FIG. When someone pulls the drawer 502 forward to move the drawer 502 from the closed state shown in FIG. 17 to the open state shown in FIG. The portion 522A is engaged with the distal end portion of the operation lever 534, and rotates the operation lever 534 in the direction DF indicated by the arrow in FIG. The rotation of the operating lever 534 is performed against the elastic force of the coil spring corresponding to the coil spring 34 of the first embodiment, and causes the coil spring to store elastic energy.

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 forward as shown in FIG.

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

  When the operating lever 534 is pulled out from the closed state shown in FIG. 17 to the opened state shown in FIG. 18, the microcontroller of the pull-out signal generating device 530 controls the wireless communication circuit, Thus, a detection signal indicating that the drawer 502 has been opened is communicated to the external terminal device.

The rotation of the operating lever 534 is performed against the elastic force of the coil spring corresponding to the coil spring 34 of the first embodiment, and causes the coil spring to store elastic energy.

  When the rotation operation position of the operation lever 534 reaches a predetermined rotation position, as in the first embodiment, the rotation body of the extraction signal generation device 530 moves relative to the operation unit by the elastic force of the coil spring. 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, so that the operation plate spring 522 is elastically deformed. Due to this elastic deformation, the operating leaf spring 522 passes below the distal end of the operating lever 534 and moves rearward from the distal end of the operating lever 534 as shown in FIG.

  When the operating lever 534 is pushed from the opened state shown in FIG. 18 to the closed state shown in FIG. 17, the microcontroller of the pull-out signal generator 530 controls the wireless communication circuit, Thus, a detection signal indicating that the drawer 502 has been closed is communicated to the external terminal device.

[Effects of Third Embodiment]
Generally, when storing important documents and the like in the drawer 502, a lock device is provided in the drawer 502. When someone breaks the locking device and opens and closes the drawer 502, the withdrawal signal generator 530 of this embodiment can communicate a detection signal indicating the opening and closing of the drawer 502 to an external terminal device.

  Even when the drawer 502 is opened and closed slowly, the drawer signal generator 530 of the present embodiment can generate a relatively large electric signal in the signal generator by the action of the coil spring.
