FIG. 5 is a front view of another example of the seismic detector of the present invention, and FIG. 6 is a side view in which a part of another example of the seismic detector of the present invention is shown in section.

In the figure, reference numeral 1 denotes an earthquake detector, and a holding portion 1b for detachably attaching and holding an electric device portion 2 such as a TR radio described later is formed in a concave shape on an upper surface or a lower surface of a main body 1a having a substantially box shape. It is formed and equipped. Reference numeral 1c denotes a locking projection having elasticity for locking the electric device section 2 formed by projecting a convex shape on both inner surfaces of the holding section 1b.

Inside the box-shaped main body 1a, when a vibration due to an earthquake or the like is received, the spherical body 3 which is displaced by falling from the supporting portion 1d is supported as a vibration sensor in a shallow concave portion. While forming the support portion 1d, the movable contact 4c is pushed directly below the support portion 1d by the sphere 3 and the limit switch 4 held on the side is arranged as a switch body of the earthquake detection portion 1. . Therefore, the limit switch 4 is turned off when the sphere 3 falls from its supporting portion 1d.

The limit switch 4 of the earthquake detection unit 1 has one terminal 4b connected in series to a relay 5 and both terminals 4a and 4b of the switch 4 act on the relay 5. Is formed as an example of an earthquake detection circuit by forming connection terminals 6a and 6b which are connected to both ends of the make contact 5a and are connected to the power supply circuit of the electric equipment section 2 such as a TR radio which will be described later. .

One terminal 4b of the limit switch 4 connected to the relay 5 is connected to the power supply circuit of the electric equipment section 2 via the other terminal of the make contact 5a. It is formed on the connection terminal 6c, and an example of the vibration detection circuit of the earthquake detection unit 1 is formed by the above configuration.

The electric device section 2 includes a box-shaped body 2a, a TR radio 21, a flashlight 22, an electronic buzzer 23, a shared power source 24 for these devices, and a dry battery here. It is formed into an equipped one-body type electrical device. On the outer surface of the body 2a, recesses 2b corresponding to the left and right locking projections 1c provided on the inner surface of the recessed holding portion 1b of the earthquake detector 1 are formed.

Here, a convex switch actuating protrusion 7 is formed on the upper surface of the holding portion 1b of the earthquake detecting portion 1, while the convex portion is formed on the bottom surface of the body 2a of the electric device portion 2. A hole 2c for receiving the actuating projection 7 is formed. Inside the hole 2c of the body 2a, a limit switch 8 is arranged as a second switch body of the electric device section 2 described later with its movable contact piece 8d facing the hole 2c. 8a to 8c are contacts of this limit switch.

The power source 24 is connected to each of the devices 21 to 23 on the negative side as a common ground line of the devices 21 to 23, and is formed on the holding portion 1b on the bottom surface of the body 2a as a common negative terminal 25b. It is arranged at a position facing one terminal 6b of the earthquake detection circuit. On the other hand, the + side of the power supply 24 is connected to the + side connection terminal 25a arranged on the bottom surface of the body 2a so as to face the other terminal 6a of the earthquake detection circuit.

Each electric device, in this example, the TR radio 21 and the flashlight 22 has the positive side of its power supply circuit branched in parallel via the changeover switches 9 and 10, respectively. The contacts 9b, 9c and 10b, 10c forming the respective branch lines connect one contact 9b, 10b to one contact 8a of the limit switch 8 and the other contact 9c, 10c of the branch line. The switch 8 is connected to the other contact 8b, and is also connected to a terminal 25c installed opposite to the connection terminal 6c formed on the holding portion 1b of the earthquake detector 1. The + side line of the electronic buzzer -23 is connected to the + side terminal 25a of the holding section 1b connected to the + side of the power source 24 by inserting the open / close switch 11 and the limit switch 8 mentioned above. Connected to contact 8c.

An example of the earthquake detector of the present invention is constructed as described above, and an operation example thereof will be described below.

The seismic detector 1 of the present invention is mounted on a wall W of a room with the holding portion 1b of the electric device portion 2 facing upward in the state shown in FIG. 1, and the TR radio 21 and the power source 24 are attached to the holding portion 1b. The electric device portion 2 having the above-mentioned components housed in the one body 2a is mounted by engaging the body 2a with the holding portion 1b at the engaging protrusions 1c and the recesses 2b.

The earthquake detector 1 can be installed in any direction such as the upside-down posture shown in FIG. 5 or the horizontal posture shown in FIG. The orientation of the sphere 3 as the seismic sensor and its supporting portion 1d, and the position of the limit switch 4 facing the sphere 3 are adjusted in advance to the mounting posture of the seismic detector 1 as illustrated in FIGS. It is assumed that

Now, when the seismic detector of the present invention is installed in the mounted state of FIG. 1, its circuit state is assumed to be the state of FIG. That is, in the limit switch 4 of the earthquake detection unit 1, the movable contact piece 4c is pushed down because the sphere 3 is left stationary on the support portion 1d, and the contacts 4a and 4b are opened. In the limit switch 8 provided in the electric equipment part 2, the movable contact piece 8d is pushed up by the actuating projection 7 to bring the contacts 8a and 8b into a conductive state.

On the other hand, in the TR radio 21, the movable contact 9a of the changeover switch 9 is positioned on the contact 9b side, and in the flashlight 22, the movable contact 10a of the changeover switch 10 is also positioned on the contact 10b side. Has been. The switch 11 of the electronic buzzer 23 is turned off. Here, the contacts 9b and 10b of the changeover switches 9 and 10 mean that the TR radio 21 and the flashlight 22 are turned on and on, and the contacts 9c and 10c mean that they are turned off. That is, the TR radio 21 and the flashlight 22 of the electric equipment part 2 are cut off from the power supply 24 when the changeover switches 9 and 10 are placed in the on / standby positions, while the circuit of the earthquake detection part 1 is Since the make contact 5a, which is connected to the power supply 24 through the open limit switch 4 and is closed by the operation of the relay 5, is opened, the TR radio 21 and the flashlight 22 are kept inactive.

In this state, when the earthquake detection unit 1 detects a vibration due to an earthquake or the like, and the sphere 3 of the detection circuit falls from the supporting portion 1d, the movable contact piece 4c of the limit switch 4 separates from the sphere 3. The contacts 4a and 4b are connected to be in a conductive state, whereby the relay 5 is activated and the make contact 5a is closed, so that the TR radio 21 and the flashlight are electrically connected to the power source 24 to operate. Enter the state.

Therefore, even if an earthquake occurs at night and the location of the seismic detector of the present invention is not visible to the eye, the TR radio 21 and the flashlight 22 automatically start operating. The location can be easily found. When the radio 21 is activated and the flashlight is turned on, the user can go near the electric equipment section 2 and remove the equipment section 2 from the holding section 1b.

While the radio 21 and the flashlight 22 are operating, if the body 2a housing them is removed from the holding portion 1b of the detector 1, the circuit on the side of the earthquake detection portion 1 and the electric equipment portion 2 are removed. The circuit on the side is separated and cut off at the connection terminal portions 6a to 6c and 25a to 25c of both circuits, but due to this removal, the movable contact piece 8d of the limit switch 8 that has been pushed up to the operating projection 7 up to that point. Lowers to connect terminals 8a and 8c to form a new power supply circuit that is connected to the power supply 24, so that the TR radio 21 and the flashlight 22 are connected to the power supply 24. The same operating state can be maintained.

Therefore, a person who wants to evacuate to the outside or the like can take the body 2a accommodating the TR radio 21 and the flashlight 22 as it is and take a safe evacuation action. Moreover, the switch of the electronic buzzer 23 can be turned on and off at any timing when the electric device section 2 is attached to the holding section 1b or removed. You can ring it freely at this point, which is useful for letting others know your whereabouts.

If the TR radio 21 and the flashlight 22 become useless after the evacuation, the switches 9 and 10 can be switched to the contacts 9c and 10c on the off side, respectively, so that the conduction state with the power supply 24 is maintained. Since the power is cut off to be in the off state, waste of the power supply 24 can be suppressed.

The seismic detector of the present invention of the above-described embodiment has the seismic detecting portion even if the changeover switches 9 and 10 of the respective devices 21 and 22 are tilted to the contact points 9c and 10c side, that is, the cut side. When 1 detects a vibration and the sphere 3 falls from its supporting portion 1d to make the limit switch 4 conductive, the TR radio 21 and the flashlight 22 are activated.

However, when the changeover switches 9 and 10 are in the open side (contact points 9c and 10c side), when the electric device section 2 is detached from the holding section 1b of the earthquake detection section 1, Since the power supply circuit connecting the power supply 24 and each device 21, 22 is opened, the operation of each device 21, 22 stops. In addition, the circuit of the seismic detection unit 1 is disconnected from the power supply 24 when the electric device unit 2 is removed from the holding unit 1b regardless of which side the electric device side changeover switches 9 and 10 are. , I cannot receive the power supply.

In the seismic detector of the present invention, when the sphere 3 is accidentally or intentionally fallen from the supporting portion 1d to activate each device 21, 22 of the electric device part 2, the electric device part 2 is removed from the holding part 1b, the sphere 3 is returned to the original position, and the device part 2 is attached to the holding part 1b to return to the original standby state.

The seismic detector of the present invention adjusts the mass and size of the sphere 3 and the depth (caliber) of the concave portion of the supporting portion 1d to adjust the falling sensitivity of the sphere 3, that is, the seismic intensity of the sphere 3. The motion sensitivity can be set freely. Further, in the embodiment of the present invention, as the electric equipment, the TR radio 21, the flashlight 22, and the electronic buzzer 23 are of a type and structure that are integrated into one body type. Is a combination of the equipment in the above example and other equipment, or a combination of other equipment, or one of them is independently attached to the holding portion 1b in a removable manner. It is entirely optional. For example, a combination of the flashlight 22 and the electronic buzzer 23 or a combination of the flashlight 22 and the TR radio 21 may be used.

FIG. 5 is a plan view of the seismic detection device of the present invention in which a holding portion 1b for the electric equipment portion 2 is formed on the lower surface of the earthquake detection portion 1 and the electric equipment portion 2 is detachably attached to the holding portion 1b from below. It is a front view of another example of a container. FIG. 6 is a side view of another example of the earthquake detector of the present invention in which the electric device section 2 is detachably attached to the side surface of the earthquake detection section 1. In any of the examples, the same reference numerals as those in FIGS. 1 to 4 indicate the same members and the same parts.

In the present invention, the connection state between the earthquake detection unit 1 and the electric device unit 2 is such that the electric device unit 2 does not drop off from the earthquake detection unit 1 due to a vibration such as an earthquake, and the connection state is manually released. That is, it must be possible to easily remove the side of the equipment unit 2. Therefore, in the first embodiment shown in FIGS. 1 to 3, the locking projections 1c, 1c of the holding portion 1b are formed as elastic convex portions, but this portion is attracted by magnetic force or surface fasteners. The force may be used alone or in combination with the male and female locking structure.
