(Embodiment 1)
Hereinafter, a vibration generator 10 according to an embodiment of the present invention will be described with reference to FIGS. 1A to 1C. The vibration generating device 10 is provided in a trolley (strike box) c that covers a space in which the dead bolt a and the latch bolt b are inserted when, for example, an entrance door having a dead bolt type lock is closed. The dead bolt a, the latch bolt b, and the trolley c are made of metal.

The vibration generator 10 generates a specific vibration when a specific movement is caused by a specific operation of the operator. In the present embodiment, the dead bolt a before the lock is displaced from the unlocked position (first position) to the locked position (second position) by the operation (locking operation) of locking the lock of the operator (locking operation). That is, the dead bolt a moves forward in the direction of the trolley c (from the unlocked position to the locked position).
In the present embodiment, when the dead bolt a is displaced from the unlocked position to the locked position, the vibration generating device 10 generates vibration at a predetermined specific frequency using energy generated by the displacement from the unlocked position to the locked position. Occur. As shown in FIG. 1A, the vibration generator 10 includes a contact portion 11, a support base 12, and a contact vibration portion 13.

  The contact portion 11 is connected to the inner surface of the troyoke c. The abutting portion 11 abuts against the dead bolt a when the dead bolt a is displaced from the unlocked position to the locked position by the locking operation. The abutting portion 11 is preferably formed of a highly rigid member in order to transmit energy due to the displacement of the dead bolt a to the trolley c. In addition, the abutting portion 11 may include a damper or the like that attenuates energy in a frequency region that deviates from the specific frequency in order to easily generate vibration at a predetermined specific frequency.

  The support base 12 has an annular shape as shown in FIGS. 1B and 1C. The support base 12 supports the contact vibration part 13. The support base 12 is connected to the outer surface of the troyoke c. The support base 12 is made of, for example, a metal or permanent magnet having a plate thickness of 0.1 mm, an outer diameter of 22.0 mm, and an inner diameter of 20.0 mm.

  The contact vibration part 13 has a circular shape. The contact vibration part 13 is connected to the surface of the support 12 that faces the surface to which the trolley c is connected. In other words, the contact vibration part 13 is attached to the trolley c via the support base 12. The contact vibration part 13 is made of, for example, a disc-shaped phosphor bronze having a plate thickness of 0.1 mm and a diameter of 22.0 mm. With this configuration, the contact vibration unit 13 generates a vibration having a predetermined natural vibration frequency (specific frequency, for example, 550 Hz) using energy transmitted when the dead bolt a hits the contact unit 11. . That is, when the dead bolt a hits the contact portion 11, the contact vibration portion 13 resonates with the excitation caused by the contact, and generates a vibration with a predetermined natural vibration frequency. It is preferable that the surface of the contact vibration part 13 that contacts the dead bolt a is formed in a curved surface so that the contact vibration part 13 makes point contact with the dead bolt a. In addition, the contact vibration part 13 may be formed integrally with the support base 12.

  When the dead bolt a is displaced from the unlocked position to the locked position by the locking operation, the dead bolt a hits the contact portion 11. In this case, impulse vibration is generated in the abutting portion 11 and the trolley c. The contact vibration unit 13 resonates with the impulse excitation, thereby generating a vibration of, for example, 550 Hz (specific frequency).

  By measuring the vibration generated by the contact vibration part 13, the locking operation to the entrance door can be determined. For example, the vibration generated by the contact vibration unit 13 is measured by a vibrometer. The measured vibration data is output from the vibrometer to the computer. The computer determines that it is locked when the measured vibration generated by the contact vibration unit 13 has a frequency of, for example, 530 Hz to 570 Hz and exceeds a predetermined amplitude. Thereby, it is possible to determine the operation of locking the entrance door by the computer.

  In the present embodiment, when the contact vibration part 13 vibrates due to the vibration generated when the dead bolt a and the contact part 11 abut (for example, knocking to the entrance door), the contact vibration part 13 is Does not resonate with vibration. In this case, for example, the contact vibration unit 13 generates vibration having a frequency outside the frequency range of 530 Hz to 570 Hz, or vibration having a frequency of 530 Hz to 570 Hz and a small amplitude.

  As described above, in the present embodiment, the contact vibration part 13 resonates with the impulse excitation generated when the dead bolt a hits the contact part 11, and therefore the vibration generator 10 has the dead bolt a When it abuts against the contact portion 11, a specific vibration (a vibration having a predetermined frequency and exceeding a predetermined amplitude) can be generated. In other words, the vibration generator 10 does not generate a specific vibration except that the dead bolt a hits the contact portion 11. Therefore, the vibration generator 10 makes it easy to determine whether the vibration is generated by performing a locking operation (operation) or the vibration generated by an operation (operation) other than locking.

  Further, the difference between the natural vibration frequency of the contact vibration part 13 and the resonance frequency of the path through which energy due to the contact between the dead bolt a and the contact part 11 is propagated to the contact vibration part 13 is within a predetermined range. (For example, within ± 20 Hz) is preferable. In other words, when the dead bolt a hits the contact portion 11, it is preferable that the contact vibration portion 13 resonates with vibration in the propagation path from the contact portion 11 to the contact vibration portion 13. Thereby, in the vibration generator 10, when the dead bolt a hits the contact part 11, the vibration which has a frequency of 530 Hz-570 Hz, for example is excited.

(Embodiment 2)
A vibration generator 20 according to Embodiment 2 of the present invention will be described with reference to FIGS. 2A to 2C. As shown in FIG. 2A, the vibration generator 20 includes a rectangular support base 22 instead of the support base 12 in the first embodiment. The vibration generator 20 includes a rectangular contact vibration unit 23 instead of the contact vibration unit 13 in the first embodiment. In the present embodiment, the same configurations and the same processes as those of the vibration generator 10 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The rectangular support base 22 has a rectangular shape as shown in FIGS. 2B and 2C. The rectangular support base 22 supports the rectangular contact vibration part 23. The rectangular support base 22 is connected to the outer surface of the troyoke c. The rectangular support base 22 is made of a metal or a permanent magnet, like the support base 12 of the first embodiment. For example, the plate thickness of the rectangular support base 22 is 0.1 mm. Moreover, the external dimension La in the longitudinal direction of the rectangular support base 22 is 30.0 mm. The inner dimension in the longitudinal direction of the rectangular support base 22 is 28.0 mm. Furthermore, the external dimension Lb in the short direction of the rectangular support base 22 is 10.0 mm. The inner dimension of the rectangular support base 22 in the short direction is 8.0 mm.

  The rectangular contact vibration part 23 has a rectangular shape. The rectangular contact vibration part 23 is connected to the rectangular support base 22 as shown in FIG. 2A. For example, the plate thickness of the rectangular contact vibration part 23 is 0.1 mm. Moreover, the dimension La of the longitudinal direction of the rectangular contact vibration part 23 is 30.0 mm. Further, the dimension Lb in the short direction of the rectangular abutting vibration part 23 is 10.0 mm. The rectangular abutment vibration part 23 is made of phosphor bronze, like the abutment vibration part 13 of the first embodiment. With this configuration, the rectangular abutting vibration part 23 generates a vibration having a predetermined natural vibration frequency (for example, 550 Hz) using energy transmitted when the dead bolt a hits the abutting part 11. That is, when the dead bolt a hits the contact portion 11, the rectangular contact vibration portion 23 resonates with the vibration caused by the contact and generates a vibration having a predetermined natural vibration frequency. The rectangular abutment vibration part 23 may be formed integrally with the rectangular support base 22.

  When the dead bolt a is displaced from the unlocked position to the locked position by the locking operation, the dead bolt a hits the contact portion 11. In this case, impulse vibration is generated in the abutting portion 11 and the trolley c. The rectangular abutting vibration part 23 generates vibration of, for example, 550 Hz by resonating with the impulse excitation. Here, when the rectangular abutment vibration part 23 vibrates due to the vibration generated by the dead bolt a being abutted against the abutment part 11 (for example, knocking to the entrance door), the rectangular abutment vibration part 23 is Does not resonate with vibration. Therefore, the rectangular abutting vibration part 23 generates vibrations having a frequency outside the frequency range of 530 Hz to 570 Hz, or vibrations having a frequency of 530 Hz to 570 Hz with a small amplitude.

  As described above, in the present embodiment, the rectangular abutting vibration part 23 resonates with the impulse vibration generated when the dead bolt a hits the abutting part 11. When it hits against the contact part 11, a specific vibration (a vibration having a predetermined frequency and exceeding a predetermined amplitude) can be generated. Therefore, the vibration generator 20 makes it easy to determine whether the vibration is generated by performing a locking operation (operation) or the vibration generated by an operation (operation) other than locking.

  In FIGS. 1A to 1C and FIGS. 2A to 2C, the contact vibration part 13 and the rectangular contact vibration part 23 are connected to a position facing the contact part 11 in Troyoke c. 13. The position of the rectangular contact vibration part 23 is not limited to this. The contact vibration part 13 and the rectangular contact vibration part 23 may be connected to the upper and lower surfaces and side surfaces of the troyoke c. Moreover, the contact vibration part 13 and the rectangular contact vibration part 23 may be connected to a position not in contact with the dead bolt a on the inner surface of the trolley c.

(Embodiment 3)
A vibration generator 30 according to Embodiment 3 of the present invention will be described with reference to FIGS. 3A and 3B. Similarly to the first and second embodiments, the vibration generating device 30 is provided in a trolley (strike box) c that covers a space in which the dead bolt a and the latch bolt b provided in the entrance door are inserted.

The vibration generating device 30 generates a specific vibration when a specific movement is caused by a specific operation of the operator. In the present embodiment, the deadbolt a before the lock is displaced from the lock position (second position) to the unlock position (first position) by unlocking the lock of the operator (unlocking operation) (unlocking). Operation). In other words, the dead bolt a moves backward in the direction opposite to the trolley c (from the locked position to the unlocked position).
Specifically, the vibration generating device 30 uses energy generated when the dead bolt a is displaced from the locked position to the unlocked position (unlocking operation) when the dead bolt a is displaced from the locked position to the unlocked position. Thus, vibration of a predetermined specific frequency is generated.

  As shown in FIGS. 3A and 3B, the vibration generating device 30 includes a bullet-like contact portion 31, a movable plate 32, a winding spring 33, a fixed plate 34, and a fastener 35. The bullet-like contact portion 31 is a bullet-like magnet inserted in a through hole formed in the troyoke c. When the dead bolt a is positioned at the locked position (locked state), the bullet-like contact portion 31 is in a state of abutting against the dead bolt a as shown in FIG. 3A.

  The movable plate 32 is connected to the surface opposite to the tip of the bullet-like contact portion 31 that abuts against the dead bolt a, perpendicular to the axis of the bullet-like contact portion 31.

  The winding spring 33 is fixed to the movable plate 32 at one end and the outer surface of the trolley c with one end in a state where the bullet-like contact portion 31 is inserted. The winding spring 33 applies a biasing force (restoring force) to the bullet-like contact portion 31 in a state where the dead bolt a and the bullet-like contact portion 31 are in contact with each other.

  The fixed plate 34 is composed of a dish-shaped metal plate. The fixed plate 34 limits the displacement of the bullet-like contact portion 31 and the movable plate 32.

  The fastener 35 fixes one end of the fixing plate 34 to the trolley c. Since the other end of the fixed plate 34 is not fixed, the force transmitted to the movable plate 32 can be released by the fixed plate 34 when the dead bolt a hits the bullet contact portion 31 with a strong force. However, the fixed plate 34 is not limited to a plate that is fixed only at one end, and both ends of the fixed plate 34 may be fixed to the trolley c.

  When the unlocking operation is performed in a state where the dead bolt a and the bullet-like contact portion 31 are in contact with each other (locked state) shown in FIG. 3A, the dead bolt a is, as shown in FIG. It is displaced from the locked position to the unlocked position. That is, the dead bolt a is displaced in a direction away from the bullet-like contact portion 31. When the biasing force (restoring force) of the winding spring 33 becomes larger than the attractive force of the bullet-shaped contact portion 31 and the dead bolt a by the magnet due to the displacement of the dead bolt a, the bullet-shaped contact portion 31 Move away from the dead bolt a. The coil spring 33 expands and contracts by the urging force (elastic energy) of the coil spring 33. The expansion and contraction of the winding spring 33 causes the bullet-like contact portion 31 to vibrate at a predetermined frequency (system natural vibration frequency, for example, 100 Hz).

  By measuring the vibration generated by the bullet-like contact portion 31, the unlocking operation to the entrance door can be detected. For example, the vibration generated by the bullet-like contact vibration unit 31 is measured by a vibrometer. The measured vibration data is output from the vibrometer to the computer. When the vibration generated by the measured bullet-like contact portion 31 has a frequency of, for example, 90 Hz to 110 Hz and exceeds a predetermined amplitude, the computer determines that the lock is unlocked. Thereby, it is possible to determine the unlocking operation of the entrance door by the computer.

  As described above, when the dead bolt a and the bullet-like contact portion 31 are separated from each other, the vibration generating device 30 can be identified by expanding and contracting the winding spring 33 using the elastic energy stored in the winding spring 33. Vibration (vibration having a predetermined frequency and exceeding a predetermined amplitude) can be generated. In other words, the vibration generating device 30 does not generate a specific vibration except when the dead bolt a and the bullet contact portion 31 are separated. Therefore, the vibration generating device 30 makes it easy to determine whether the vibration is generated by performing an unlocking operation (operation) or is generated by an operation (operation) other than unlocking.

  In the present embodiment, when the dead bolt a is in a locked state, the winding spring 33 may be in a state of being contracted from the natural state or a state of being extended from the natural state.

(Embodiment 4)
A vibration generator 40 according to Embodiment 4 of the present invention will be described with reference to FIGS. 4A and 4B. Similarly to the vibration generator 30 of the third embodiment, the vibration generator 40 is provided in a trolley (strike box) c that covers a space in which the dead bolt a and the latch bolt b provided in the entrance door are inserted.

  The vibration generator 40 generates a specific vibration when a specific movement is caused by a specific operation of the operator. Specifically, as in the vibration generator 30 of the third embodiment, when the dead bolt a is displaced from the locked position to the unlocked position, the vibration generator 40 is moved from the locked position to the unlocked position. The vibration of a predetermined specific frequency is generated using the energy generated by the displacement (unlocking operation).

  As shown in FIGS. 4A and 4B, the vibration generator 40 includes a rod abutting portion 41, a movable plate 42, a reverse winding spring 43, and a case 44. The rod abutting portion 41 is a rod-like magnet inserted in a through hole (a through hole formed in a horizontal surface in the displacement direction of the dead bolt a) formed in the trowel c. When the dead bolt a is positioned at the locked position (locked state), the rod abutting portion 41 is in a state of abutting against the dead bolt a by the attractive force of the rod-shaped magnet as shown in FIG. 4A.

  The movable plate 42 is connected to the surface opposite to the end of the rod contact portion 41 that abuts against the dead bolt a, perpendicular to the axis of the rod contact portion 41.

  The reverse winding spring 43 is fixed to the movable plate 42 at one end and to the outer surface of the troyoke c with the rod abutting portion 41 inserted therein. The reverse winding spring 43 applies an urging force (restoring force) to the rod abutting portion 41 in a state where the dead bolt a and the rod abutting portion 41 abut against each other. That is, the reverse winding spring 43 is in a state of being contracted from the natural state when the bar abutting portion 41 abuts against the dead bolt a due to the attractive force of the magnet of the bar abutting portion 41.

  The case 44 is a plastic plate having a hook shape. As shown in FIG. 4B, the case 44 limits the displacement of the movable plate 42 when the rod contact portion 41 and the dead bolt a are separated.

  When the unlocking operation is performed in a state in which the rod abutting portion 41 and the dead bolt a shown in FIG. 4A are in contact with each other (locked state), the dead bolt a is locked as shown in FIG. 4B by the unlocking operation. Displace from position to unlocked position. Due to the displacement of the dead bolt a, the dead bolt a and the bar contact portion 41 are separated from each other, and the reverse winding spring 43 returns from the contracted state to the normal state (the extended state). That is, when the dead bolt a and the rod contact portion 41 are separated from each other, the vibration generating device 40 uses the elastic energy stored in the reverse winding spring 43 to expand and contract the reverse winding spring 43 to thereby extend the rod contact portion. 41 is vibrated at a predetermined specific frequency (system natural vibration frequency, for example, 100 Hz).

  By measuring the vibration generated by the bar abutting portion 41, the unlocking operation to the entrance door can be determined. For example, the vibration generated by the rod abutting portion 41 is measured with a vibrometer. The measured vibration data is output from the vibrometer to the computer. The computer determines that the unlocking occurs when the vibration generated by the measured bar contact portion 41 has a frequency of, for example, 90 Hz to 110 Hz and exceeds a predetermined amplitude. Thereby, it is possible to determine the unlocking operation of the entrance door by the computer.

  In this way, when the dead bolt a and the bar abutting portion 41 are separated from each other, the vibration generating device 40 is caused to expand and contract by using the elastic energy of the reverse winding spring 43 so that the vibration generating device 40 can generate a specific vibration (predetermined). (Vibration having a frequency and exceeding a predetermined amplitude). In other words, the vibration generating device 40 does not generate a specific vibration except when the dead bolt a and the bar contact portion 41 are separated. Therefore, the vibration generating device 40 facilitates discrimination between vibrations generated by performing an unlocking operation (operation) or vibrations generated by an operation (operation) other than unlocking.

  In the third and fourth embodiments, the elastic bodies that vibrate the bullet contact portion 31 and the rod contact portion 41 are the winding spring 33 and the reverse winding spring 43, respectively. The elastic body which vibrates the contact part 41 is not limited to these. The elastic body that vibrates the bullet-shaped contact portion 31 and the rod contact portion 41 may be an elastic body such as a leaf spring. The elastic body that vibrates the bullet-shaped contact portion 31 and the rod contact portion 41 may be an elastic body in which a leaf spring is added to the winding spring 33 or the reverse winding spring 43.

(Embodiment 5)
Next, a vibration generator 50 according to Embodiment 5 of the present invention will be described with reference to FIGS. 5A to 5D. The vibration generating device 50 is provided inside a trolley (strike box) c that covers a space in which the dead bolt a and the latch bolt b provided in the entrance door are inserted.

  The vibration generator 50 generates a specific vibration when a specific movement is caused by a specific operation of the operator. Specifically, the vibration generating device 50, like the vibration generating device 40 of the fourth embodiment, opens the dead bolt a from the locked position when the dead bolt a is displaced from the locked position to the unlocked position. A vibration having a predetermined specific frequency is generated using energy generated by the displacement to the lock position (unlocking operation).

  As shown in FIG. 5A, the vibration generating device 50 includes a contact maintaining portion 51, a holding spring 52, and a fixture 53. The contact maintaining part 51 is a bullet-shaped magnet. The contact maintaining part 51 is held by a holding spring 52. The contact maintaining part 51 is disposed in a space covered by the trojan c. The holding spring 52 is fixed to the trolley c by a fixing tool 53. As shown in FIG. 5B, the contact maintaining portion 51 is in close contact with the dead bolt a by the attractive force of the magnet when the dead bolt a is located at the locked position (locked state). That is, the contact maintaining part 51 generates a force for maintaining contact with the dead bolt a. In addition, as for the contact maintenance part 51, the edge part opposite to the surface which contacts the dead bolt a has a projection shape. Therefore, the suction force between the contact maintaining part 51 and the dead bolt 51 is larger than the suction force between the contact maintaining part 51 and the troyoke c.

  The holding spring 52 is, for example, a T-shaped leaf spring. The first end (the upper end in FIG. 5A) of the holding spring 52 is connected vertically to the axial direction of the contact maintaining portion 51. A second end (the right end in FIG. 5A) of the holding spring 52 is connected to the inner surface of the troyoke c by the fixture 53. A third end (lower end in FIG. 5A) of the holding spring 52 protrudes outside the troyoke c through a hole provided in the troyoke c. The holding spring 52 holds the contact maintaining portion 51 so as to be swingable. Note that the holding spring 52 is in a state (deformed) in which the contact maintaining portion 51 is pressed against the trolley c even in a natural state (a state where the contact maintaining portion 51 is in contact with the trolley c). State).

  The fixing tool 53 connects the holding spring 52 to the inner surface of the trolley c.

  As shown in FIG. 5A, when the dead bolt a is located at the unlocked position (unlocked state), the contact maintaining part 51 comes into contact with the trolley c. When the dead bolt a is displaced from the unlocked position to the locked position by the locking operation, as shown in FIG. 5B, the contact maintaining portion 51 comes into contact with the trolley c and the dead bolt a. On the other hand, when the dead bolt a is displaced from the locked position to the unlocked position by the unlocking operation, as shown in FIG. 5C, the suction force between the contact maintaining portion 51 and the dead bolt a is Since it is larger than the suction force with Troyoke c, the contact maintaining part 51 follows the displacement of the dead bolt a. Then, the restoring force of the holding spring 52 becomes larger than the suction force between the contact maintaining part 51 and the dead bolt a, and the contact maintaining part 51 is separated from the dead bolt a as shown in FIG. 5D. The contact maintaining portion 51 that is separated from the dead bolt a vibrates due to the restoring force of the holding spring 52. That is, when the contact maintaining part 51 is separated from the dead bolt a, the vibration generating device 50 uses the elastic energy stored in the holding spring 52 to cause the contact maintaining part 51 to move to a predetermined specific frequency (system frequency). It is vibrated at a vibration frequency (for example, 100 Hz).

  By measuring the vibration generated by the contact maintaining portion 51, the unlocking operation to the entrance door can be determined. For example, the vibration generated by the contact maintaining unit 51 is measured by a vibrometer. The measured vibration data is output from the vibrometer to the computer. The computer determines that the unlocking occurs when the measured vibration generated by the contact maintaining unit 51 has a frequency of, for example, 90 Hz to 110 Hz and exceeds a predetermined amplitude. Thereby, it is possible to determine the unlocking operation of the entrance door by the computer.

  As described above, when the dead bolt a and the contact maintaining portion 51 are separated from each other, the vibration generating device 50 is caused to vibrate by using the elastic energy stored in the holding spring 52 to vibrate the holding spring 52. Vibration (vibration having a predetermined frequency and exceeding a predetermined amplitude) can be generated. In other words, the vibration generating device 50 does not generate a specific vibration except when the dead bolt a and the contact maintaining portion 51 are separated. Therefore, the vibration generator 50 facilitates discrimination between vibrations generated by the unlocking operation (operation) or vibrations generated by other operations (operations).

  In addition, when the contact maintenance part 51 leaves | separates from the dead bolt a, the contact maintenance part 51 stops in the state which contacted the troyoke c, after repeating the collision with the trojoke c. However, in the vibration generating device 50 according to the present embodiment, the contact maintaining unit 51 does not have to repeatedly collide with the trolley c.

A vibration generator 60 according to Embodiment 6 will be described with reference to FIGS. The vibration generator 60 is attached to the front door lock. The entrance door is made of steel. The lock on the front door is a dead bolt type. The dimension of the entrance door is vertical: about 1800 mm × width: about 1000 mm.

  As shown in FIG. 6, the vibration generator 60 includes a leaf spring 63, a permanent magnet 64, a first protrusion 65, and a second protrusion 66. The leaf spring 63 is made of phosphor bronze. The permanent magnet 64 is composed of a ferrite magnet. The first protrusion 65 and the second protrusion 66 are made of a magnetic material. The leaf spring 63 is substantially L-shaped and one side is fixed to the trolley c. The permanent magnet 64 is attached to the leaf spring 63. Further, the leaf spring 63 has a hole in a region facing the first protrusion 65.

  In addition, the leaf | plate spring 63, the permanent magnet 64, the 1st projection part 65, and the 2nd projection part 66 are not limited to the above-mentioned structure, You may be comprised from various materials. Moreover, the attachment position of the leaf | plate spring 63, the permanent magnet 64, the 1st projection part 65, and the 2nd projection part 66 is not limited to the position shown in FIG. For example, the leaf spring 63 may be fixed to the trolley c at the end in the left-right direction, and the first protrusion 65 and the second protrusion 66 may be arranged in the left-right direction.

  The operation of the vibration generating device 60 having the above configuration will be described for a case where a locking operation is performed on the entrance door. 7 to 9 show the operation of the vibration generator 60 in the locking operation.

As shown in FIG. 6, the leaf spring 63 of the vibration generating device 60 does not come into contact with the first protrusion 65, the second protrusion 66, and the trolley c when the lock is unlocked.
Due to the locking operation, the dead bolt a is gradually displaced in the direction of the trolley c. When the distance between the dead bolt a and the trolley c reaches a predetermined distance, the permanent magnet 64 of the vibration generating device 60 is attracted to the dead bolt a by the magnetic force as shown in FIG. Bolt a contacts. Further, when the dead bolt a is displaced in the direction of the trolley c, the leaf spring 63 comes into contact with the second protrusion 66 as shown in FIG. Then, as shown in FIG. 9, the dead bolt a contacts the first protrusion 65.

  The vibration generated by the vibration generator 60 by the operation of the series of vibration generators 60 described above will be described. FIG. 10 shows a vibration waveform signal at a specific frequency of vibration generated by the vibration generator 60 when a locking operation is performed. In the present embodiment, the vibration waveform signal represents the amplitude of vibration.

  In a series of operations of the vibration generating device 60, the vibration generating device 60 includes the contact between the permanent magnet 64 and the dead bolt a, the contact between the second protrusion 66 and the leaf spring 63, and the first protrusion 65 and the leaf spring 63. A damped vibration of a specific frequency is generated due to each of the contacts.

  In general, when the dead bolt a is displaced to a predetermined position, the dead bolt a is displaced at a constant speed by the lock cam mechanism regardless of the excitation force (operation) by the operator. Therefore, when the dimension (characteristic) of the leaf spring 63 is set, the damping caused by the contact between the second protrusion 66 and the leaf spring 63 is caused by the generation of the damping vibration caused by the contact between the permanent magnet 64 and the dead bolt a. The time until the occurrence of vibration (time Ta1 in FIG. 10) is also set. Further, the time from the generation of the damped vibration due to the contact between the second protrusion 66 and the leaf spring 63 to the occurrence of the damped vibration due to the contact between the first protrusion 65 and the leaf spring 63 (time Ta2 in FIG. 10). ) Is similarly set.

  Next, the operation of the vibration generator 60 will be described for a case where an unlocking action is performed on the entrance door. 11 to 13 show the operation of the vibration generating device 60 in the unlocking operation.

  In the unlocking operation, the dead bolt a is displaced in a direction away from the trolley c. When the dead bolt a is displaced in a direction away from the trolley c, the leaf spring 63 is displaced together with the dead bolt a by the attractive force between the permanent magnet 64 and the dead bolt a, as shown in FIG. Then, the leaf spring 63 moves away from the first protrusion 65 and the second protrusion 66 in the order of the first protrusion 65 and the second protrusion 66. Further, when the dead bolt a is separated from the trolley c by a predetermined distance, the restoring force of the leaf spring 63 becomes larger than the attractive force between the permanent magnet 64 and the dead bolt a. Therefore, as shown in FIG. The magnet 64 and the dead bolt a are separated. In this case, free vibration depending on dimensions (characteristics) is generated in the leaf spring 63, and the leaf spring 63 collides with the second protrusion 66 as shown in FIG.

  The vibration generated by the vibration generator 60 by the operation of the series of vibration generators 60 described above will be described. FIG. 14 shows a vibration waveform signal at a specific frequency of vibration generated by the vibration generator 60 in the unlocking operation.

  In a series of operations of the vibration generator 60, the vibration generator 60 performs vibration caused by free vibration of the leaf spring 63 and damped vibration of a specific frequency caused by collision between the leaf spring 63 and the second protrusion 66. Occur.

  Also in the unlocking operation, as in the case of the locking operation, the size (characteristic) of the leaf spring 63 is set, so that the leaf spring 63 and the second protrusion are prevented from generating vibration due to the free vibration of the leaf spring 63. The time until the occurrence of the damped vibration due to the collision 66 (time Tb in FIG. 14) is set.

  Therefore, by measuring the vibration generation interval at the specific frequency generated by the vibration generating device 60, it is possible to determine the locking operation and the unlocking operation of the entrance door. In addition, the operator's operation can be determined by combining the generation interval and amplitude of vibration at a specific frequency generated by the vibration generator 60.

  It was confirmed as follows that the operation of the operator can be determined by measuring the vibration (vibration waveform signal) of a specific frequency generated by the vibration generator 60 in the present embodiment.

  15 and 16 show the determination condition for the locking operation and the determination condition for the unlocking operation, respectively. In FIG. 15, the threshold value Ra1 is a threshold value for determining whether or not a damped vibration caused by the contact between the permanent magnet 64 and the dead bolt a has occurred (determination J1). The threshold Ra2 is a threshold for determining whether or not a damped vibration caused by the contact between the second protrusion 66 and the leaf spring 63 has occurred (determination J2). Further, the threshold value Ra3 is a threshold value for determining whether or not a damped vibration caused by the contact between the first protrusion 65 and the leaf spring 63 has occurred (determination J3).

  In FIG. 15, time Ta <b> 1 is the time from the contact between the permanent magnet 64 and the dead bolt a to the contact between the second protrusion 66 and the leaf spring 63. That is, when a locking operation is performed, a damped vibration caused by the contact between the second protrusion 66 and the leaf spring 63 occurs after a time Ta1 from the occurrence of the damped vibration caused by the contact between the permanent magnet 64 and the dead bolt a. To do. In the present embodiment, it is determined whether or not a damped vibration caused by the contact between the second protrusion 66 and the leaf spring 63 has occurred in a period of 5 mS before and after the time Ta1 (determination J2).

The time Ta2 is a time from the contact between the second protrusion 66 and the leaf spring 63 until the contact between the first protrusion 65 and the leaf spring 63 occurs. That is, when the locking operation is performed, the damped vibration due to the contact between the first protrusion 65 and the leaf spring 63 after the time Ta2 from the occurrence of the damped vibration due to the contact between the second protrusion 66 and the leaf spring 63. Will occur. In the present embodiment, it is determined whether or not a damped vibration caused by the contact between the first protrusion 65 and the leaf spring 63 has occurred in a period of 3 mS before and after the time Ta2 (determination J3).
In the present embodiment, when the vibration signal exceeds the threshold value Ra1 (determination J1), it is determined in the determination J2 that the vibration signal exceeds the threshold value Ra2, and it is determined in the determination J3 that the vibration signal exceeds the threshold value Ra3. The operation performed on the entrance door is determined as “unlocking operation”.

  In FIG. 16, a threshold value Rb1 is a threshold value for determining whether or not free vibration of the leaf spring 63 caused by the separation of the permanent magnet 64 and the dead bolt a has occurred (determination J4). The threshold value Rb2 is a threshold value for determining whether or not a damped vibration caused by the contact between the leaf spring 63 and the second protrusion 66 has occurred (determination J5).

  The time Tb1 is the time from the occurrence of free vibration of the leaf spring 63 due to the separation of the permanent magnet 64 and the dead bolt a to the occurrence of contact between the leaf spring 63 and the second protrusion 66. That is, when the unlocking operation is performed, the contact between the leaf spring 63 and the second projecting portion 66 after the time Tb1 from the occurrence of the free vibration of the leaf spring 63 due to the separation of the permanent magnet 64 and the dead bolt a. The resulting damped vibration occurs. In the present embodiment, it is determined whether or not a damped vibration caused by the contact between the leaf spring 63 and the second protrusion 66 has occurred in a period of 5 mS before and after the time Tb1 (determination J5).

  In the detection of the unlocking action, if the vibration signal exceeds the threshold value Rb1 (determination J4), and it is determined in the determination J5 that the vibration signal exceeds the threshold value Rb2, the operation performed on the entrance door is determined as “unlocking operation”. Is done.

Under the above conditions, the locking operation and the unlocking operation were performed 10 times each on the entrance door where the vibration generator 60 according to the present embodiment was installed. Moreover, the door was opened and closed and the door chain was opened and closed 10 times each as a disturbance. As a result, the disturbance was not determined as “locking action” or “unlocking action”. In addition, all locking operations on the front door were determined to be “locking acts”. Furthermore, all unlocking operations on the front door were determined as “unlocking act”.
As described above, by measuring the vibration generated by the vibration generator 60, the operation of the operator can be easily determined.

A vibration generator 70 according to Embodiment 7 will be described with reference to FIGS. As shown in FIG. 17, the vibration generator 70 in the present embodiment includes leaf springs 73a and 73b, permanent magnets 74a and 74b, a first protrusion 75a, a second protrusion 76a, a fixed protrusion 77, and a fastener 78a. 78b. The vibration generator 70 has two sets of vibrators. One set is a leaf spring 73a, a permanent magnet 74a, and a first protrusion 75a. The other set is a leaf spring 73b, a permanent magnet 74b, and a second protrusion 76a. The leaf springs 73a and 73b are made of phosphor bronze. Permanent magnets 74a and 74b are composed of ferrite magnets. The 1st projection part 75a and the 2nd projection part 76a are comprised from a magnetic material. The fixed projection 77 is made of a highly rigid material such as iron. Furthermore, the fasteners 78a and 78b fix the leaf springs 73a and 73b to the trowel c, respectively.

In the present embodiment, the rigidity of the leaf spring 73a is larger than the rigidity of the leaf spring 73b. On the other hand, the permanent magnet 74a and the permanent magnet 74b are the same permanent magnet. However, the attraction force by the permanent magnet 74a may be stronger than the attraction force by the permanent magnet 74b, and the leaf spring 73a and the leaf spring 73b may have the same rigidity.
The leaf springs 73a and 73b, the permanent magnets 74a and 74b, the first protrusion 75a, the second protrusion 76a, and the fixed protrusion 77 are not limited to the above configuration. The leaf springs 73a and 73b, the permanent magnets 74a and 74b, the first protrusion 75a, the second protrusion 76a, and the fixed protrusion 77 may be made of various materials. Further, the attachment positions of the leaf springs 73a, 73b and the like are not limited to the configuration shown in FIG. Further, the leaf springs 73a and 73b may be arranged in the left-right direction.

  The operation of the vibration generating apparatus 70 having the above configuration will be described for a case where the door door is locked. 17 to 20 show the operation of the vibration generator 70 in the locking operation.

As shown in FIG. 17, the leaf springs 73 a and 73 b of the vibration generating device 70 do not contact the first protrusion 75 a, the second protrusion 76 a, and the trolley c when the lock is unlocked.
Due to the locking operation, the dead bolt a is gradually displaced in the direction of the trolley c. When the distance between the dead bolt a and the trolley c reaches a predetermined distance, as shown in FIG. 18, the permanent magnet 74b is attracted to the dead bolt a by a magnetic force, and the permanent magnet 74b and the dead bolt a come into contact with each other. . Next, as shown in FIG. 19, the permanent magnet 74a is attracted to the dead bolt a by the magnetic force, and the permanent magnet 74a and the dead bolt a come into contact with each other. Further, when the dead bolt a is displaced in the direction of the trolley c, the dead bolt a comes into contact with the fixed protrusion 77 as shown in FIG.

The vibration generated by the vibration generating device 70 by the operation of the series of vibration generating devices 70 described above will be described. FIG. 21 shows a vibration waveform signal at a specific frequency of vibration generated by the vibration generator 70 in the locking operation.
In a series of operations of the vibration generator 70, the vibration generator 70 is in contact with the permanent magnet 74b and the dead bolt a, in contact with the permanent magnet 74a and the dead bolt a, and in contact with the dead bolt a and the fixed protrusion 77. Causes a damped vibration of a specific frequency.

  In general, when the dead bolt a is displaced to a predetermined position, the dead bolt a is displaced at a constant speed by the cam mechanism of the lock regardless of the excitation force (operation) by the operator. Therefore, when the dimensions (characteristics) of the leaf springs 73a and 73b are set, the damping caused by the contact between the permanent magnet 74a and the dead bolt a due to the generation of the damped vibration caused by the contact between the permanent magnet 74b and the dead bolt a. The time until the occurrence of vibration (time Tc1 in FIG. 21) is also set. Also, the time from the generation of the damped vibration caused by the contact between the permanent magnet 74a and the dead bolt a to the time when the damped vibration caused by the contact between the dead bolt a and the fixed projection 77 (time Tc2 in FIG. 21) is also obtained. It is set similarly.

The operation of the vibration generator 70 will be described for a case where the locking operation is performed on the entrance door. 22 to 24 show the operation of the vibration generator 70 in the unlocking operation.
In the unlocking operation, the dead bolt a is displaced in a direction away from the trolley c. When the dead bolt a is displaced in a direction away from the trolley c, the leaf springs 73a and 73b are displaced together with the dead bolt a by the attractive force between the permanent magnets 74a and 74b and the dead bolt a, as shown in FIG. Then, when the dead bolt a is separated from the Troyoke c by a predetermined distance, the restoring force of the leaf spring 73a becomes larger than the attractive force between the permanent magnet 74a and the dead bolt a, so as shown in FIG. The permanent magnet 74a is separated from the dead bolt a. In this case, free vibration depending on the dimensions (characteristics) is generated in the leaf spring 73a, and the first protrusion 75a collides with the trolley c. Further, when the dead bolt a is away from the trolley c, the restoring force of the leaf spring 73b becomes larger than the attractive force of the permanent magnet 74b and the dead bolt a. Therefore, as shown in FIG. Move away from bolt a. Also in this case, free vibration depending on the dimensions (characteristics) is generated in the leaf spring 73b, and the second protrusion 76a collides with the trolley c.

  The vibration generated by the vibration generating device 70 by the operation of the series of vibration generating devices 70 described above will be described. FIG. 25 shows a vibration waveform signal at a specific frequency of vibration generated by the vibration generator 70 in the unlocking operation.

  In a series of operations of the vibration generating device 70, the vibration generating device 70 is used for vibration caused by free vibration of the leaf spring 73a, damped vibration caused by collision between the first protrusion 75a and the troyoke c, and free vibration of the leaf spring 73b. The vibration caused by this and the damped vibration caused by the collision between the second protrusion 76a and the trolley c are sequentially generated.

  In general, when the dead bolt a is displaced to a predetermined position, the dead bolt a is displaced at a constant speed by the cam mechanism of the lock regardless of the excitation force (operation) by the operator. Therefore, when the size of the leaf spring 73a is set, the time from the occurrence of free vibration of the leaf spring 73a to the occurrence of the damped vibration caused by the collision between the first protrusion 75a and the troyoke c (time Td1 in FIG. 25) is also obtained. Is set. Also, by setting the dimensions (characteristics) of the leaf springs 73a and 73b, the time from the occurrence of vibration due to the collision between the first protrusion 75a and the troyoke c to the occurrence of free vibration of the leaf spring 73b (FIG. The time Td2) at 25 is also set. Furthermore, when the dimension of the leaf spring 73b is set, the time from the occurrence of free vibration of the leaf spring 73b to the occurrence of damped vibration due to the collision between the second protrusion 76a and the troyoke c (time Td3 in FIG. 25) is also obtained. Is set.

  Accordingly, by measuring the vibration generation interval at the specific frequency generated by the vibration generating device 70, it is possible to determine the locking operation and unlocking operation of the entrance door. It is also possible to determine the operation of the operator by combining the vibration generation interval and amplitude at the specific frequency generated by the vibration generator 70.

Good. This combined vibration generator can generate vibrations both by the locking operation and by the unlocking operation. Furthermore, the combined vibration generating device can generate vibrations of different frequencies depending on the operation (locking operation and unlocking operation). Therefore, the combined vibration generator facilitates discrimination between vibrations generated by the locking operation, vibrations generated by the unlocking operation, and vibrations generated by other than these. Further, when combining the vibration generating device 10 or 20 and the vibration generating device 50, the contact maintaining unit 51 may also serve as the bullet-shaped contact unit 31.

  In the first to seventh embodiments, the vibration generators 10, 20, 30, 40, 50 are provided on the trolley c fixed to the entrance door (structure), so that the vibration generators 10, 20, 30, 40 are provided. , 50 can be easily measured and wiring of the measurement mechanism can be facilitated. However, the vibration generators 10, 20, 30, 40, and 50 may be provided in a lock case that houses the dead bolt a, for example. In the lock case, the dead bolt a is retracted by the operator's locking operation. Further, the dead bolt a moves forward by the unlocking operation of the operator. Therefore, when the vibration generating device 10 is provided in the lock case, the vibration generating device 10 generates vibration by the unlocking operation of the operator. For example, when the vibration generating device 30 is provided in a lock case, the vibration generating device 30 generates vibration by an operator's locking operation.

  The vibration generator of the present invention may be provided in a sliding window or the like. In this case, the vibration generating device of the present invention generates vibration of a predetermined specific frequency by using energy generated by opening and closing a sliding window or the like.

  In the sixth and seventh embodiments, the vibration generators 60 and 70 generate the damped vibration twice or more by the operation of the operator. However, the vibration generators 60 and 70 may vibrate only once by the operation of the operator. . In this case, the operation of the operator can be determined by determining whether or not the vibration signal in a specific frequency region exceeds a predetermined threshold value.

  In the sixth and seventh embodiments, the vibration generators 60 and 70 are attached to the trolley c. However, the vibration generators 60 and 70 are, for example, a case that accommodates the dead bolt a, a window frame, a wall of a structure, and the like. It may be attached.

  Although the vibration generator 60 includes the leaf spring 63, the vibration generator 60 may include a coil spring or the like instead of the leaf spring 63. Further, the vibration generator 60 may include a coil spring in addition to the leaf spring 63. Further, the vibration generating device 70 includes the leaf springs 73a and 73b, but may include a coil spring or the like instead of the leaf springs 73a and 73b. The vibration generator 70 may include a coil spring in addition to the leaf springs 73a and 73b.

  In the third to fifth embodiments, in order to maintain the abutted state, for example, a suction force by a magnet is applied between the bullet-like contact portion 31 and the dead bolt a, but instead of the suction force by the magnet, Further, a force for closely attaching the hook-and-loop fastener may be applied.
