Description

The present invention relates to an automatic unlocking system at the time of an earthquake that automatically unlocks a sliding door from the inside by the tension of a spring when an earthquake occurs without using electricity. In particular, the present invention relates to an automatic earthquake unlocking system that can unlock the thumb turn of a sliding door more smoothly than a conventional earthquake automatic unlocking device.

  A storage for life-saving emergency equipment is installed at neighborhood associations. Local governments also actively subsidize and recommend the installation of lifesaving equipment and storage. However, the sliding door of the storage is normally locked for crime prevention, so that the sliding door cannot be opened without a matching key. Therefore, if a private house collapses due to a strong earthquake, it will not be possible to take out the equipment necessary to rescue the person trapped in it without a key.

As countermeasures in that case, the following several methods are taken in each present situation in each neighborhood association.
1. Several related keys are created and stored by several people.
2. Hiding the secret key near the vault or invisible to the public so that only the person concerned can understand.
3. Attach a lock that can be unlocked with a PIN.
4). Keep the key in a private house near the vault.
5. Make sure that the sliding door can be opened at any time without a lock.
Although the method has been taken as described above, it seems that there are cases where it is difficult to cope with any earthquake other than the above item 5. In recent years, there are many residents' associations and neighborhood associations who are in trouble because of the aging of society, and there is no need to keep their keys, so there is an increasing number of neighborhood associations and neighborhood associations taking the method described in the above item 2.

To solve this problem, Utility Model Registration No. 3144509 as Conventional Example 1 discloses an unlocking device that detects an earthquake and automatically and reliably unlocks the lock of a steel plate shed. This uses a pendulum weight that detects earthquakes. However, this apparatus has a problem that it is not easy to use because it detects the vibration caused by opening and closing the door because the apparatus is installed inside the door contact surface. Utility Model Registration No. 3145311 as Conventional Example 2 discloses an unlocking device based on the same technical idea, but has the same problems as Reference 1. Utility Model Registration No. 3148810 as Conventional Example 3 also discloses an unlocking device based on the same technical idea, but has the same problems as Reference Example 1. Furthermore, in the earthquake detection devices disclosed in these references, the movement of each member from the detection of the earthquake to the unlocking is linear, and for this reason, the frictional resistance with the peripheral members is large, and thus the unlocking is smooth. There is a problem that the operation is not performed.

In order to deal with the above-mentioned problems, Japanese Patent Application Laid-Open No. 2010-222843 by the applicant of the present application as Reference 4 installs an earthquake detection device for detecting an earthquake on the inner wall surface of the hut, and provides an unlocking device for the sliding door. A self-unlocking device is disclosed that includes a connecting device that connects an earthquake sensing device and an unlocking device with a connecting wire. In this apparatus, since the seismic sensing device is installed on the inner wall surface of the hut, since the seismic sensing device senses only an earthquake, the problems in Reference 1 to Reference 3 are eliminated. Further, as a reference 5, a similar configuration is disclosed in Japanese Patent Laid-Open No. 2011-1788.

However, in these Reference Example 4 and Reference Example 5 as well, when an earthquake is detected in the earthquake sensing device, the biased spring force is released and the peripheral member is pulled linearly, so that the frictional resistance is large. However, the problem that the unlocking operation is not performed smoothly has not been solved. Furthermore, in the connecting device that connects the earthquake sensing device and the unlocking device, the peripheral member simply connected to the connecting wire operates linearly, so the frictional resistance between the peripheral members is large, and in this respect also, the unlocking is smooth. It also had the problem of not being done. For this reason, even in the event of an earthquake that is detected with high sensitivity by the corner earthquake detector, there still remains a structural defect that the unlocking operation is not smoothly transmitted to the essential unlocking device. Moreover, these references have a problem that the unlocking operation is not performed smoothly even inside the unlocking device. In addition, if a conventional earthquake detection device is installed in a storage shed, for example, if you forget to set it in the earthquake detection mode in which this device operates when an earthquake occurs, close the sliding door and lock it, the folding device will also be There was a serious defect that the value was lost, but there was also a problem that no special consideration was given to this defect.

In order to solve the problems in the unlocking device according to the prior art as described above,
(1) In the seismic sensing device, each member is configured to be able to perform sensing operation smoothly by rotating operation instead of linear motion,
(2) Even in the connecting device that connects the earthquake sensing device and the unlocking device, the connecting operation can be smoothly performed by the rotating operation instead of the linear operation of the member,
(3) Further, the unlocking device can be configured to smoothly perform the unlocking operation by the energized spring spring.
(4) In addition, in order to ensure that this system operates in the event of an earthquake, an earthquake with a configuration in which a restriction plate is added that indicates that the sliding door cannot be closed if you forget to set the operation of the earthquake detection device before closing the sliding door. It aims to provide an automatic unlocking system.

The automatic unlocking system at the time of an earthquake of the present invention comprises an earthquake sensing device that detects an earthquake by swinging a pendulum weight, an unlocking device provided on a sliding door lock, an earthquake sensing device, and an unlocking device. It is configured to automatically unlock the sliding door from the inside by the tension of the spring when an earthquake occurs, which is constituted by a connecting device connected by a connecting wire. In this earthquake sensing device, when the earthquake is detected by the amplitude of the pendulum type weight, the stopper that has been locked is released from the stopper arm, and the rotating plate biased by the drive spring rotates, so that the coupling device is connected. The wire is configured to be pulled. Accordingly, since the drive spring is pulled for the unlocking operation by the rotation of the rotating plate, the connecting wire is pulled by the rotating operation instead of the conventional linear operation, so that a smooth operation is possible.

Further, in the connecting device, the arm at one end of the L-shaped arm of the fixed connecting portion connected to the pulled connecting wire rotates counterclockwise around the L-shaped arm axis, and the other end of the rotated L-shaped arm. Since the lifting roller provided on the arm of the arm is configured to lift the unlocking wire by lifting the sliding connection portion that is in sliding contact to the upper side of the lifting plate, the operation is the same as in the above-described earthquake sensing device. Smooth connection operation becomes possible. In addition, in order to ensure that this system operates in the event of an earthquake, if you forget to set the operation of the seismic detector before closing the sliding door, a restriction plate will be placed in the gap between the sliding door and the door column. Since it is added, it has a configuration that can prevent forgetting to set.

Furthermore, since the unlocking wire is connected to the unlocking device via the wound spring spring, the unlocking wire is not loosened in either the unlocked state or the locked state. Therefore, it is possible to rotate the thumb turn at once by the restoring force of the drive spring of the earthquake sensing device.

In addition, the seismic sensing device is simple because it rotates the rotating plate to the position where the stopper arm engages with the stopper by manually rotating the set handle or pulling down the set suspension ring. It is possible to set the earthquake detection device to the earthquake detection mode.

In addition, the fixed connecting portion and the slide connecting portion of the connecting device are configured so as to be in sliding contact with each other or to be separated from each other when the sliding door is opened and closed, so that they are connected only when the sliding door is in a closed state. As before the installation of the device, the sliding door can be freely opened and closed.

In addition, the unlocking device is configured such that the wound spring spring and the unlocking wire are connected, and the unlocking wire is not loosened in the unlocked state or the locked state, so that the unlocking and locking operations are stable. It becomes possible to do.

  The seismic sensing device, unlocking device, and connecting device are connected through the rotation operation without sliding with other members in a linear motion as in the conventional example, and the thumb turn is rotated by the connecting wire. , Has the merit of unlocking more smoothly. Further, the provision of the restriction plate makes it possible to reliably set the earthquake sensing device in the earthquake sensing mode.

It is the perspective view which looked at the state at the time of sliding door closing from the storage room interior. That is, the earthquake automatic unlocking system 1 of the present application includes an earthquake sensing device 100, a connecting device 200, and an unlocking device 300. The earthquake sensing device 100 senses the occurrence of an earthquake. When an earthquake is detected, the connecting wire 221 is pulled to rotate the thumb turn 305 of the unlocking device 300 via the connecting device 200, thereby unlocking. Each device will be described below.

FIG. 3 is a perspective view showing the appearance of the earthquake sensing device 100 according to the present invention. 4 is a left perspective view showing a state of the earthquake sensing device 100 during an earthquake standby, that is, when locked, and FIG. 5 is a right perspective view. In the figure, by manually rotating the rotatable set handle 127 clockwise, the stopper arm 108 engages with the stopper 107 to enter an earthquake standby state, that is, an earthquake detection mode. 6 and 7 are plan views showing the seismic sensing device 100 with the set handle 127 removed. FIG. 6 shows a state during an earthquake standby, that is, a locked state, and FIG. 7 shows a state when an earthquake occurs, that is, an unlocked state. In order to place the earthquake detection device 100 in the earthquake standby state (earthquake detection mode) as described above, it is also possible to lower the set suspension ring 215 of the coupling device 200 described later. Further, a rotating roller may be attached to the stopper 107 so that the stopper 107 and the stopper arm 108 can be easily engaged and disengaged.

A base 101 shown in FIG. 5 is formed of a rectangular metal plate, and mounting legs 101b having mounting holes 101c are formed at four corners. The rotating plate 102 is formed of a circular metal plate, but may be a synthetic resin material. The set handle 127 shown in FIGS. 4 and 5 is fixed to the rotating plate and is rotated by hand to engage the stopper 107 with the claw portion of the stopper arm 108.

The connecting wire 221 has a left end fixed to the rotating plate 102, and the wire guide 122 is attached to the base 101 together with the wire stopper 124 by a wire presser 123.

  As shown in FIG. 6, the rotating plate shaft 103 is provided at the rotation center of the rotating plate 102, and one end is fixed to and supported by the base 101. The stopper arm shaft 109 rotatably supports the stopper arm 108 so as to be swingable, and is fixed to the base 101. The drive spring 104 is energized by manually rotating the rotary plate 102 to the right. One end of the drive spring 104 is attached to a drive spring upper post 105 provided on the rotary plate 102 and the other end is below a drive spring provided on the base 101. Attached to the post 106.

  The adjustment screw 113 changes the amplitude of the pendulum weight 118 by adjusting the gap between the push-up bar 115 and the adjustment receiving plate 114, and is provided for the purpose of fine adjustment of the amplitude. The adjustment receiving plate 114 is provided to align the contact points between the push-up bar 115 and the adjustment screw 113 on one line.

  The locking spring 110 engages and urges the stopper arm 108 and the stopper 107. One end is attached to the stopper arm 108 and the other end is attached to the base 101.

  The pendulum-type weight 118 is set to a predetermined weight, and is attached to the push-up disk 112 through the suspension shaft 120 at the center. The push-up disc 112 is attached to the weight receiving base 117, and the suspension shaft 120 is slidably inserted into an opening formed larger in diameter than the suspension shaft 120.

  The passive plate 111 moves up and down following the swaying of the push-up disc 112, and is formed with a push-up rod 115 to push up the stopper arm 108. The push-up bar 115 is guided by a push-up bar guide 116 so as to be movable up and down.

The functional operation of the earthquake sensing device 100 will be described below with reference to FIG. The drive spring 104 is attached to the outer periphery of the rotating plate 102 by a drive spring upper post 105. When the pendulum weight 118 swings due to the occurrence of an earthquake, the push-up disc 112 pushes up the passive plate 111 that moves freely up and down. Then, the push-up rod 115 is pushed upward, and the stopper arm 108 supported by the stopper arm shaft 109 releases the engagement with the stopper 107. The rotating plate 102 is urged to rotate counterclockwise by the drive spring 104. Therefore, the connecting wire 221 whose left end is fixed to the rotating plate 102 along the groove provided on the outer periphery of the rotating plate 102 is pulled leftward to unlock the unlocking device 300.

When the pendulum weight 118 swings due to the occurrence of an earthquake, the stopper arm 108 supported by the stopper arm shaft 109 releases the engagement with the stopper 107 and is urged to rotate counterclockwise by the drive spring 104. The connecting wire 221 fixed to the rotating plate 102 along the groove provided on the outer periphery of the rotating plate 102 being pulled can be pulled leftward to unlock the unlocking device 300. In this way, the connecting wire 221 is pulled by the rotating operation of the rotating plate 102, so that the operation is extremely smooth compared to the conventional seismic sensing device by the linear operation, and therefore, the operation for unlocking is performed with high sensitivity when an earthquake occurs. Can be done.

8, 9, and 10 are front views showing the coupling device 200. Among these, FIG. 8 is a front view showing the coupling device 200 according to the present invention immediately before the sliding door is closed. In the figure, the right side is a fixed connection part 210 installed in the hut main body, and the left side is a slide connection part 250 installed in the sliding door. FIG. 9 is a front view showing the time of locking, and FIG. 10 is a front view showing the time of unlocking. The connecting device 200 is composed of a fixed connecting portion 210 and a slide connecting portion 250, so that the sliding door can be freely opened and closed, and a connecting wire that is pulled in the direction of the earthquake detecting device 100 when an earthquake is detected. This is because the tension of 221 is smoothly transmitted to the unlocking device 300 installed in the sliding door 52. That is, when an earthquake occurs, the connecting wire 221 is pulled to the earthquake sensing device 100 side (left in the figure). In this case, the seismic drive device 100 and the connecting device 200 are connected by the connecting wire 221, and the biasing force of the drive spring 104 provided in the seismic drive device 100 of FIG. This is transmitted to the unlocking device 300 via the fixed connecting portion 210 and the slide connecting portion 250.

Hereinafter, functional operations of the coupling device 200 will be described with reference to FIGS. 9 and 10. An L-shaped arm 211 is provided at a fixed connecting portion 210 installed on a beam or a column of a hut so as to be rotatable about an L-shaped arm shaft 212. A lifting roller 213 is provided at a substantially middle point of the lower arm of the L-shaped arm 211, and the tip of the upper arm is pulled leftward by the connecting wire 221. On the other hand, the slide connecting portion 250 installed on the sliding door side is provided with a lifting plate 252 on the top of the slide bar 251 that can slide up and down. When the sliding door 52 slides in the closing direction (right direction) and closes, the lifting plate 252 slides on the lifting roller 213. When the earthquake is detected, the rotating plate 102 is rotated counterclockwise by the biasing force of the drive spring 104 of the earthquake detecting device 100, whereby the connecting wire 221 having one end fixed to the rotating plate 102 is pulled leftward. As shown in FIG. 10, the L-shaped arm 211 of the fixed coupling portion 210 to which the other end of the coupling wire 221 is coupled is provided on the lower arm of the L-shaped arm 211 when rotated about the L-shaped arm shaft 212. The raised roller 213 is pulled upward. Along with the upward movement of the pulling roller 213, the pulling plate 252 of the slide connecting portion 250 installed on the sliding door that is in sliding contact with the pulling roller 213 is lifted upward. Then, the unlocking wire 253 connected to the slide bar 251 integrated with the lifted lifting plate 252 is pulled upward, and the unlocking device 300 is unlocked. Note that the lower arm of the L-shaped arm 211 is connected to a later-described regulating plate 230 by an L-shaped arm spring 214.

With the above configuration, when an earthquake is detected, the connecting wire 221 from the earthquake sensing device 100 attached to the inner wall surface of the building is pulled leftward, and the L-shaped arm 211 rotates around the L-shaped arm shaft 212. In addition, since the unlocking wire 253 is smoothly pulled upward, the friction with the peripheral members due to the linear operation according to the conventional example is reduced, and as a result, a smooth unlocking operation is possible. That is, similar to the rotation operation of the rotating plate 102 in the earthquake sensing device 100, in this connection device 200, the connection operation is performed very smoothly by the rotation operation of the L-shaped arm 211. Therefore, the unlocking operation is performed with high sensitivity when an earthquake occurs. It becomes possible.

Next, FIGS. 11A and 11B are a perspective view and a cross-sectional view when the regulating plate 230 according to the present invention is in a horizontal state in order to regulate the closing of the sliding door, and FIG. And (B) are a perspective view and a cross-sectional view when the sliding door is allowed to be closed and is in a vertical state. The regulation plate 230 is a plate that is rotatably attached to the regulation plate shaft 231 inside the door-to-door pillar 41, and regulates the closing of the sliding door 52 when the earthquake detection device 100 is not set in the earthquake detection mode. That is, if the restricting plate 230 rotates to the horizontal position as shown in FIG. 11B, the restricting plate 230 rotated to this horizontal position enters the gap between the sliding door 52 and the door-to-door pillar 41, and the sliding door 52 is completely removed. Cannot be closed, so the lock cannot be locked. That is, when the rotating plate 102 of the earthquake sensing device 100 in FIG. 7 is resting at a counterclockwise position (that is, in a state where the earthquake sensing mode is not set), the connecting wire 221 shown in FIG. In this state, the right end of the L-shaped arm 211 is lifted upward, and the L-shaped arm spring 214 is pulled. Then, the restriction plate 230 rotates counterclockwise around the restriction plate shaft 231 as the rotation axis, and the restriction plate 230 faces in the horizontal direction as shown in FIG. In this case, the restriction plate 230 becomes an obstacle and the sliding door 52 does not close up to the door-to-door pillar 41, and the person who finally leaves the storage room forgets to set the earthquake detection device 100 to the earthquake detection mode. It is possible to reliably prevent the situation where the sliding door 52 is closed.

  In the case where the sliding door 52 is prevented from being inadvertently closed by the restriction plate 230 as described above, a person who leaves the storage shed can remove the set suspension ring 215 shown in FIG. Put your hand and pull it down. Then, the L-shaped arm 211 rotates clockwise with the L-shaped arm shaft 212 as the rotation axis, the connecting wire 221 is pulled to the right, and the earthquake sensing device 100 is reliably set to the earthquake sensing mode. In this case, the L-type arm spring 214 is in a state in which the tension is released when the right end of the L-type arm 211 is lowered, and the regulating plate 230 is released from the L-type arm spring 214. When released, the restricting plate 230 is rotated by another small spring (not shown) until it becomes clockwise and the sliding door 52 is closed to the position of the door-to-door pillar 41 as shown in FIG. Is acceptable. Thus, the restriction plate 230 according to the present invention makes it possible for the person who leaves the storage shed to reliably set the earthquake detection device 100 in the earthquake detection mode before closing and locking the sliding door. The shape of the regulating plate 230 is not limited to the illustrated plate shape, and may be any shape as long as it regulates the closing of the sliding door 52 when the earthquake sensing device 100 is not set. Further, the seismic sensing device 100 may be set by pulling down the set suspension ring 215 downward as described above, or by rotating the set handle 127 shown in FIG. 5 of the seismic sensing device 100 clockwise.

FIG. 13 is a perspective view showing the appearance of the unlocking device 300 according to the present invention. For example, the unlocking device 300 is configured by adding a later-described spring spring 302 to an existing lock 301 already installed in a sliding door. The lock 301 may be a cylinder lock or another type of lock, for example. FIG. 14 is a front view showing a state during locking, and FIG. 15 is a side view. 16 is a perspective view showing a state in which the mainspring 302 is manually wound during locking, and FIG. 17 is a perspective view showing a state in which the mainspring 302 is pulled upward during unlocking. The mainspring 302 is urged in a direction that is always wound up with a spring force that is smaller than the spring force of the drive spring 104 of the seismic sensing device 100 to the extent that no loosening occurs.

When the unlocking wire 253 of the connecting device 200 pulls the mainspring 302 during an earthquake, the drum 303 fixed to the end of the mainspring 302 rotates, and at the same time, the thumb turn 305 fixed to the drum 303 is also rotated and unlocked. . That is, when the thumb turn 305 is rotated, the hook 306 is interlocked and rotated by an existing mechanism (not shown) of the lock 301 to be released from the engagement hole 307 and unlocked. The mainspring 302 in this case is pulled upward as shown in FIG.

Next, when locking again, the set handle 127 shown in FIG. 4 is rotated clockwise or the set suspension ring 215 of the connecting device 200 shown in FIG. 8 is manually pushed downward to connect to the connecting wire 221. The rotating plate 102 is rotated clockwise, and the claw portion of the stopper arm 108 is engaged with the stopper 107. After that, when the key 308 is inserted into the lock 301 and rotated in the locking direction, the hook 306 turns into the engagement hole 307 and is locked.

When the unlocking wire 253 of the coupling device 200 is pulled upward when an earthquake is detected, the mainspring 302 wound around the drum 303 is pulled upward for unlocking as shown in FIG. When locking again, the unlocking wire 253 is lowered by pulling the set suspension ring 215 downward, and the mainspring 302 is slightly loosened as shown in FIG. It is wound on the drum 303 to the extent that it is not. As described above, the mainspring 302 is used in the unlocking device 300 because a gap is formed between the drum 303 and the mainspring 302 when unlocking by manual operation, and the drum is used when locking next time. 303 is used so that it can be completed as before. Therefore, it is preferable to use a spring spring 302 that has excellent flexibility and returns to its original shape.

In the earthquake automatic unlocking system 1 according to the present invention, unlike the prior art earthquake automatic unlocking device, when an earthquake occurs, the seismic sensing unit 100 causes the pendulum weight 118 to oscillate by the stopper arm shaft 109. Unlike the linear motion of the prior art, the connecting wire 221 that is rotatably connected to the rotating plate 102 that is pivotally supported by the pivoted stopper arm 108 that disengages the stopper 107 and rotates counterclockwise is circular. The unlocking device 300 can be unlocked by being smoothly pulled to the left by the movement. Further, in the connecting device 200, the connecting wire 221 is pulled leftward, and the L-shaped arm 211 rotates about the L-shaped arm shaft 212, so that the unlocking wire 253 is smoothly pulled upward. Friction with the peripheral members due to the linear operation according to the example is reduced, and as a result, a smooth unlocking operation is possible. Furthermore, in this connection device 200, even if the person who finally leaves the storage room forgets to set the earthquake detection device 100 in the earthquake detection mode, the restriction plate 230 is obstructive. The sliding door 52 has a structure that does not close up to the door column 41. For this reason, it becomes possible to prevent beforehand in advance that the sliding door is closed without being set to the earthquake detection mode. Further, in the unlocking device 300, the mainspring 302 is always gently wound around the drum 303 at the time of locking and unlocking, so that the thumb turn can be smoothly rotated without unnecessary interference with other members. If the earthquake automatic unlocking system 1 according to the present invention is used in a lifesaving equipment storage that is owned by local governments, residents' associations, neighborhood associations, etc., it will be useful for lifesaving when a private house collapses due to a strong earthquake. It is.
