Description

Technical Field

[0001] The present invention relates to a device for detecting seismic vibrations, and more particularly to a device that utilizes the detected vibrations as a trigger to perform functions such as those of a switch.

Background Art

[0002] Conventionally, there have been devices that detect or sense abnormal vibrations such as earthquakes and instantaneously trip switches such as breakers or cut off power supply.

[0003] For example, a seismic short - circuit device has been proposed that can prevent fire accidents caused by electrical equipment during a major earthquake by instantaneously tripping the circuit breaker in a building (Patent Document 1).

[0004] Specifically, Patent Document 1 discloses a seismic short - circuit device provided with a short - circuit ball made of a magnetic metal material that drops or flies within a desired box at or above a set seismic intensity. Below this short - circuit ball, an electrode that shorts upon contact with the short - circuit ball is disposed, and a plug terminal of the electrode is provided directly or indirectly outside the box via a conductor. In a state where the plug terminal is connected to a desired outlet disposed in the electrical wiring of a building, an over - current is passed through the electrical wiring of the building based on the short - circuit of the electrode due to the dropping or flying contact of the short - circuit ball, causing the circuit breaker of the power supply unit to operate and instantaneously interrupting the power supply to the building electrical wiring. The seismic short - circuit device is characterized in that one or more magnet members for magnetic attraction of the short - circuit balls are disposed in proximity to the lower part of the electrode.

[0005] In addition, a device has been proposed that detects when a steel ball separates from a magnet using a switch and promptly causes a power supply cut - off by a circuit breaker (Patent Document 2).

[0006] Specifically, Patent Document 2 discloses a power cutoff device characterized by comprising a magnet that attracts a steel ball to its lower surface via an attraction force adjustment member, a vertically movable lifting rod whose lower end is supported by the steel ball attracted to the magnet, and a switch that is operated by the lifting rod, which descends as the steel ball falls, to supply a tripping current to a circuit breaker installed in the power circuit.

[0007] Furthermore, a device has been proposed that automatically opens doors when an earthquake occurs (Patent Document 3).

[0008] In other words, Patent Document 3 discloses an automatic door opening device comprising: a weight; a support means for supporting the weight so that the weight can fall when vibration occurs; a door opening biasing means for opening the door by applying the spring force of a spring to the door; a disengaging means that is detachable from the door opening biasing means, which prevents the spring force from acting on the door when it is engaged with the door opening biasing means, and which is released from the door opening biasing means when the weight falls from the support means; and a release means that, when the weight falls from the support means, uses a battery as a power source to drive a locking means for fixing the door to the door frame and releases the locked state of the door relative to the door frame.

[0009] Furthermore, a method and device have been proposed that can be attached to existing circuit breakers in indoor distribution boards of houses and buildings to detect abnormal vibrations such as earthquakes, and to trip the lever switch of the circuit breaker, thereby shutting off the power circuits in the house or building and preventing fires caused by electrical leakage or abnormal heat generation (Patent Document 4).

[0010] Specifically, Patent Document 4 discloses a vibration-sensing switch-off method for a circuit breaker, characterized in that a weight is engaged with the tip of the lever switch of the circuit breaker via a string-like body, the weight engaged with the string-like body is supported on a base mounted vertically in line with the lever switch at an appropriate distance from the lever switch, statically stable and dynamically unstable due to vibrations received by the base, the weight is made capable of falling from the base when an earthquake of a certain magnitude or higher is detected, and the impact force from the falling weight lowers the lever switch and shuts off the power circuit.

[0012] However, with conventional devices and methods, the direction of the physical force generated for switching is exclusively pushing, and it was not possible to generate an effective pulling force, for example. Furthermore, it was not possible to generate a force that pulls horizontally.

[Figure 7B]This is an explanatory diagram illustrating another mode of use of an earthquake-sensing trigger device according to one embodiment of the invention, along with its operation. [Modes for carrying out the invention]

[0019] The following describes in detail an earthquake-sensing trigger device according to one embodiment of the present invention, with reference to the drawings.

[0020] Figure 1 shows the overall structure of an earthquake-sensing trigger device according to one embodiment of the present invention. The figure shows a cross-sectional view of the entire earthquake-sensing trigger device 100 from the side. In one embodiment of the present invention, the size of the earthquake-sensing trigger device 100 is not limited to these dimensions, but is approximately 10 cm to 30 cm in height and 3 cm to 8 cm in width. Furthermore, the cross-sectional shape of the earthquake-sensing trigger device 100 when viewed from above can be various shapes such as a circular shape or a rectangular shape (this will be discussed later with reference to Figures 3A and 3B).

[0021] In Figure 1, the seismic trigger device 100 has three spaces: a first space 110, a second space 120, and a third space 130. These spaces are separated by partitions 113 and 123. The upper surface of partition 113 is the bottom of the first space 110, and the lower surface of partition 113 is the ceiling of the second space 120. Similarly, the upper surface of partition 123 is the bottom of the second space 120, and the lower surface of partition 123 is the ceiling of the third space 130. 132 constitutes the bottom of the third space 130, but the bottom 132 is not necessarily an essential component (it can be omitted).

[0022] The first space 110 is equipped with support mechanisms 111 and 114 for supporting the weight, and the weight 112 which is placed on the support mechanisms 111 and 114. In one embodiment of the present invention, the weight 112 is a magnet or a magnetic material. The weight 112, placed on the support mechanisms 111 and 114, is configured to fall due to vibrations applied to the seismic trigger device 100. The degree of vibration required to cause the weight 112 to fall depends on the structure of the support mechanisms 111 and 114 (described later). The fallen weight 112 falls to the bottom of the space 110 (112' in the figure).

[0023] Furthermore, the second space 120 is equipped with a traction member 121 to which a towed member 122 is attached, so as to be inserted from the outside (the third space 130 in the figure) into the inside. The towing member 121 is normally placed on the bottom of the second space 120. In one embodiment, a hole is provided having a diameter such that the towing member 121 does not fall out of the second space 120 into the third space 130, and the towed member 122 is passed through this hole to the third space 130.

[0024] In one embodiment of the present invention, the traction member 121 is a magnet or magnetic material, and the tractioned member 122 is a string or wire of any material. Furthermore, at least one of the weight 112 and the traction member 121 is a magnet (it is not the case that both are non-magnetic). As described above, when the weight 112 falls to the bottom of the space 110, the traction member 121 provided in the second space 120 is pulled up by magnetic force and attracted to the ceiling of the space 120 (details of this operation will be described later).

[0025] The third space 130 is provided with a direction changing member 131 that allows the towed member 122 to be inserted from the inside to the outside of the third space 130 (for this purpose, the third space 130 is provided with a hole on its side in the figure), and also changes the towing direction of the towed member 122 from the vertical direction to the horizontal direction in the figure.

[0026] In one embodiment of the present invention, the direction changing member 131 is a pulley mechanism. Alternatively, it may be a rod (bar) with low frictional resistance that does not have a pulley. If the direction changing member 131 is a rod, the towed member is hung on this rod to change the direction of tension. In one embodiment of the present invention, when the towing member 121 to which the towed member 122 is attached is pulled upward in the figure, the vertical pull becomes a horizontal traction force (force in the direction of the arrow in the figure) via the direction changing member 131.

[0027] As described above, the weight 112 is configured to fall into the first space 110 due to vibrations of a predetermined magnitude when it is placed on the support mechanisms 111 and 114. Furthermore, the distance from the upper end of the traction member 121, which is normally installed in the second space 120, to the ceiling of the second space 120 is designed to be such that when the weight 112 falls to the bottom 113 of the first space 110 (falling to position 112' in the figure), the traction member 121 is attracted to the fallen weight 112' and sticks to the ceiling of the second space 120 (sticking to position 121' in the figure).

[0028] Therefore, when the towing member 121 is attracted to the fallen weight 112' and sticks to the ceiling of the second space 120, the towed member 122 is instantly pulled, and a tensile force acts on the towed member 122 extending outward from the third space 130.

[0029] Next, an example of the operation of the seismic trigger device 100 according to one embodiment of the present invention will be described with reference to Figures 2A to 2D. The same components as those in the seismic trigger device 100 shown in Figure 1 are given the same reference numerals. In the figure, P indicates a position on the tractioned member 122 that extends outside the third space 130.

[0030] Figure 2A shows the seismic trigger device 100 in its normal state. A weight 112 is placed on top of the support mechanisms 111 and 114. Furthermore, a traction member 121 is placed at the bottom of the second space 120, and a towed member 122 attached to this traction member 121 extends vertically to the third space 130 through a hole provided at the bottom, and its direction is changed to the horizontal direction via a direction changing member 131, and it extends to the outside through a hole provided on the side of the third space 130. As mentioned above, in other embodiments, the bottom portion 132 can be omitted.

[0031] Figure 2B shows the state in Figure 2A where vibration is transmitted from the outside to the seismic trigger device 100, causing the weight 112 to begin falling from the support mechanisms 111 and 114. The weight 112 falls to the bottom of the first space 110.

[0032] Figure 2C shows the weight 112 that fell in the seismic trigger device 100 in Figure 2B approaching the bottom of the first space 110. At this time, the traction member 121 placed in the second space 120 is beginning to be attracted to the weight 112 by magnetic force. Here, either the weight 112 or the traction member 121, or both, are magnets, and if either one of them is not a magnet, it is a magnetic material, so when they are within a certain distance of each other, they are attracted by their magnetic force. Figure 2C shows the state just before such attraction occurs. Then, due to this attraction phenomenon, the towed member 122 attached to the towing member 121 is pulled, and position P is drawn towards the right side in the figure (towards the seismic trigger device 100).

[0033] Figure 2D shows the state in which the weight 112, which was falling in the seismic trigger device 100 of Figure 2C, has made contact with the bottom of the first space 110. At this time, the traction member 121 placed in the second space 120 is attracted to the weight 112 via the partition 113 by magnetic force. It can be seen that position P in Figure 2D is further towards the seismic trigger device 100 than its position in Figure 2C.

[0034] Figures 3A and 3B show specific variations of the support mechanisms 111 and 114 in the configuration of an earthquake-sensing trigger device according to one embodiment of the present invention. Figure 3A illustrates a support mechanism when the cross-sectional shape of the earthquake-sensing trigger device viewed from directly above is circular, and Figure 3B illustrates a support mechanism when the cross-sectional shape of the earthquake-sensing trigger device viewed from directly above is rectangular.

[0035] In Figure 3A, the support mechanisms 311 and 314 consist of three support members 311a to 311c and a mounting base 314 for placing the weight (311 corresponds to 111 in Figure 1, and 314 corresponds to 114 in Figure 1). In the same figure, the mounting base 314 is configured in the shape of an inverted umbrella with a depression when viewed from the side. This "inverted umbrella shape" is a cone without a base, and can also be called a "conical surface" or "side surface of a cone". A concrete example is the shape of a cone made of origami with the base cut off, leaving only the side surface.

[0036] The support members 311a to 311c are configured to suspend the mounting base 314 from three sides, with the other end of each fixed to the inner wall of the seismic trigger device. The support members 311a to 311c can be made of string, wire, or other rod-shaped material, and there are no restrictions on the material as long as the strength of the support mechanism is maintained. Similarly, there are no restrictions on the material of the mounting base 314 as long as the function and strength for supporting the weight are achieved.

[0037] In Figure 3B, the support mechanisms 321 and 324 consist of four support members 321a to 321d and a mounting base 324 for placing the weight (321 corresponds to 111 in Figure 1, and 324 corresponds to 114 in Figure 1). In the same figure, the mounting base 324 is configured in the shape of an inverted umbrella with a recess when viewed from the side. The "inverted umbrella shape" here is the same as the "inverted umbrella shape" in Figure 3A, but since the cross-sectional shape of the seismic trigger device (when viewed from above) is a pyramidal pyramid, it can be described as a pyramidal pyramid without a base. A concrete example would be a pyramidal pyramid made from origami with the base cut off, leaving only the sides.

[0038] The support members 321a to 321d are configured to suspend the mounting base 324 from all four sides, with the other ends of each fixed to the four corners of the inner wall of the seismic trigger device. The support members 321a to 321d can be made of string, wire, or other rod-shaped material, and there are no restrictions on the material as long as the strength as a support mechanism is maintained. Similarly, there are no restrictions on the material of the mounting base 324 as long as the function and strength for supporting the weight are achieved.

[0039] [Adjusting earthquake sensitivity] In the seismic trigger device according to one embodiment of the present invention, the sensitivity can be adjusted by changing the shape of the inverted umbrella-shaped mounting base, as described with reference to Figures 3A and 3B, as follows. (1) Change the depth of the mounting platform. Generally, making the mounting platform deeper reduces the seismic sensitivity (making it less likely for the weight placed on the platform to fall). (2) Change the size of the top of the mounting platform. Generally, making the mounting platform wider (increasing the surface area) reduces the seismic sensitivity (making it less likely for the weight placed on the platform to fall). (3) Combine (1) and (2) above. By combining (1) and (2) above, more precise sensitivity adjustment becomes possible.

[0040] Figure 4 shows variations of the traction member, which is a component of an earthquake-sensing trigger device according to one embodiment of the present invention. In Figure 4(A), the traction member 401 is spherical. In Figure 4(B), the traction member 401 is cylindrical. The present invention is not limited to these, and various shapes of traction members can be used.

[0041] Figure 5 shows another structural example of an earthquake-sensing trigger device according to one embodiment of the present invention. The earthquake-sensing trigger device 500 shown in the figure has the same basic structure as the earthquake-sensing trigger device 100 shown in Figure 1, etc., but differs from the earthquake-sensing trigger device 100 in that it has two spaces instead of three. Aside from the differences mentioned above, 510 corresponds to 110, 520 corresponds to 120, 511 and 514 correspond to 111 and 114, 512 corresponds to 112, 513 corresponds to 113, 521 corresponds to 121, 522 corresponds to 122, and 523 corresponds to 132.

[0042] A key feature of the seismic trigger device 500 is that, although it appears in Figure 5 that the towed member 522 is pulled vertically by the towing member 521, the pulling direction can be freely set from approximately 0° (approximately horizontal) to approximately 90° (vertically downward) in terms of depression angle, and the orientation in the horizontal plane of pulling can also be freely set 360°. To achieve this performance, in one embodiment, the inside of the hole (the hole through which the towed member 522 passes) provided at the bottom of the second space 520 is rounded to reduce frictional resistance. Furthermore, when obtaining a pulling force at approximately 0° depression angle, the towed member 522 is not rubbed excessively between the upper part of the mounting base of the seismic trigger device 500 and the bottom of the device 500 when the towed member 522 is pulled. This is achieved by providing legs (not shown) at the bottom of the seismic trigger device 500.

[0043] With this configuration, when the seismic trigger device 500 is placed on some kind of flat surface, a tensile force can be obtained at a depression angle of approximately 0°. Furthermore, if the device 500 is fixed to a wall, for example, a tensile force can be obtained at any depression angle (for example, 30 degrees or 60 degrees) in any direction on the horizontal plane. Furthermore, this pulling force can be used to function as a trigger switch (a so-called pull switch) for various purposes, such as turning off the power to a light fixture, pulling the cord of an assistive device like a call alarm, or pulling a support rod.

[0044] Figure 6 shows how the seismic trigger device according to one embodiment of the invention is used. In this figure, the seismic trigger device according to one embodiment of the invention is used as a trigger device for a trap to capture birds, small animals, etc.

[0045] In Figure 6, the seismic trigger device 601 is a trigger device for pulling the support rod 603 that supports the capture umbrella 602. The lower part of the support rod 603 is tightly attached to a towed member 604. When the seismic trigger device 601 is activated by an earthquake, it instantly pulls the towed member 604, causing the support rod 603 to fall and the capture umbrella 602 to lie face down on the ground. This allows for the capture of birds, small animals, and other creatures that were inside at that time.

[0046] In Figure 6, a bait dish 6011 is provided above the seismic trigger device 601. In one embodiment, birds and small animals gather around the bait (not shown) supplied to the bait dish 6011, pecking at the bait dish 6011 or coming into contact with the seismic trigger device 601, thereby generating a certain seismic intensity in the device 601. In this way, the seismic trigger device 601 is activated, and the capture described above is successful.

[0047] Furthermore, if the seismic trigger device 601 is simply placed on the ground, the device 601 may easily tip over, preventing it from effectively transmitting traction force to the tractioned member 604. Therefore, a more suitable method for installing the seismic trigger device 601 is to first drive a fixing device into the ground (not shown), fix a mounting base made of rubber or other material to this fixing device (not shown), and then firmly fix the seismic trigger device 601 to this mounting base. This mounting base is made of rubber or other material and has elasticity, but because it is fixed to the fixing device, it does not cause the device 601 to shift position, and even in the event of sudden vibrations from the outside, it will cause a slight deflection to avoid tipping over or being damaged, thus playing a role in ensuring the stable operation of the device 601.

[0048] By installing it in this manner, the seismic trigger device 601 will not overturn or be damaged even when subjected to shaking exceeding its seismic sensitivity, and will properly receive the shaking it is supposed to detect and operate normally.

[0049] Figures 7A and 7B illustrate another mode of use of the seismic trigger device according to one embodiment of the invention, along with its operation. Figure 7A shows the state before activation, and Figure 7B shows the state after activation, illustrating a series of operations.

[0050] In Figure 7A, 702 and 703 are seismic trigger devices according to one embodiment of the invention, and the seismic trigger devices 702 and 703 are fixedly mounted on a shelf 701 such as a product shelf. 704 and 705 extending from the seismic trigger devices 702 and 703 are traction members, respectively, and are connected to spring extension devices 706 and 707, which are equipped with a pull switch (not shown) and a spring mechanism that extends by spring force. Furthermore, 708 is a bellows net mechanism attached to the spring extension devices 706 and 707.

[0051] In Figure 7A, when the spring extension devices 706 and 707 are operated as described above, the bellows net mechanism 708 is lifted upward and performs the role of a net as shown in Figure 7B.

[0052] The shelves normally hold products such as liquor bottles. Even if vibrations such as those from an earthquake are applied to the shelves, when the seismic trigger devices 702 and 703 detect an appropriate seismic intensity and activate, the net is lifted as shown in Figure 7B, preventing the liquor bottles and other products placed on the shelves 701 from falling. Furthermore, it prevents products from falling to the floor and scattering glass fragments, thus securing evacuation routes and mitigating damage in the event of an earthquake.

[0053] [Regarding magnets and magnetic materials used in weights and / or traction components] In one embodiment of the present invention, at least one or both of the weight and the traction member can be magnets (if either one of them is a magnet, the other is a magnetic material). In this embodiment, a neodymium magnet can be used as the magnet. Neodymium magnets are said to be the strongest magnets among existing permanent magnets. They have about eight times the magnetic force of a typical ferrite magnet. The strength of their magnetic force (attractive force) is such that a 1g neodymium magnet can lift a 1kg magnetic material. By using such a powerful magnet, a suitable seismic trigger device can be provided.

[0054] Furthermore, the traction force (suction force) generated by the traction member according to one embodiment of the present invention is approximately 4 N (Newtons) to 7 N (Newtons). The size of the traction member is not limited to these, but if it is spherical, it is approximately 1 cm to 5 cm in diameter, and if it is cylindrical, it is of a similar size.

[0055] [Differentiation] While the partition portion 113 in Figure 1 and the partition portion 513 in Figure 5 are shown in a planar shape for ease of understanding the invention, the present invention is not limited thereto. For example, it may be shaped like a mortar with its center as the bottom. In that case, the distance between the lowest end of the mortar-shaped partition portion and the upper end of the traction member, which is normally placed in the second space, is designed to be a distance that can sufficiently attract the fallen weight to the traction member.

[0057] Furthermore, each of the features described herein (including the claims, abstract, and drawings) may be replaced by an alternative feature that serves the same, equivalent, or similar purpose unless expressly disregarded. Thus, unless expressly disregarded, each of the disclosed features is merely an example of a comprehensive set of identical or equivalent features.

The present invention can be extended to all novel features or combinations thereof, or all novel methods or processing steps or combinations thereof, described herein (including the claims, abstract, and drawings).
