Description

  The present invention relates to a flashlight holder to which a flashlight is attached and a flashlight automatic lighting system provided with the flashlight holder, and more particularly, a flashlight holder capable of automatically turning on a flashlight in response to shaking such as an earthquake. And an automatic lighting system for a flashlight.

  Many homes and hotels have flashlights in preparation for earthquakes. Such flashlights are not usually used, so the location is often unknown at the time of disaster. In addition, the location of a flashlight may be lost due to things such as the collapse of indoor items in an earthquake. However, it is not possible to move in a dark room or outdoors without using a flashlight, especially when a power failure occurs. Even if it can move, moving in the dark is dangerous.

  Therefore, conventionally, an automatic lighting flashlight that automatically turns on in the event of a power failure has been proposed. For example, an automatic lighting flashlight described in Patent Document 1 includes a flashlight and a holder that detachably holds the flashlight, and includes a relay switch that automatically conducts when a power failure occurs.

JP 2006-210085 A

  The technique described in Patent Document 1 uses a relay switch to detect a power failure and turn on a flashlight. For example, the relay switch turns on a flashlight when supply of commercial power to an indoor outlet stops. However, in this case, there is a problem that the range in which the flashlight can be arranged is limited to the vicinity of the indoor outlet.

  In the technique described in Patent Document 1, the flashlight is not automatically turned on unless a power failure occurs. However, a power failure does not always occur during an earthquake. In this case, you may have to turn on the light when you evacuate in the dark. However, it is desirable to avoid the use of electric lights after an earthquake because there is a danger of fire due to electric leakage. Therefore, a flashlight is useful for movement after an earthquake. However, not only in unfamiliar places like hotels, but also at home, in the dark, or when indoor furniture collapses due to an earthquake, there is a problem that the location of the flashlight is not known.

  The present invention has been made to solve the above-described problems, and ensures the light at the time of the earthquake by detecting the shaking of the earthquake without using power and automatically turning on the flashlight. Provided is an automatic lighting system that can make it possible to clarify the location of a flashlight.

In order to solve the above problems, the present invention provides a flashlight automatic lighting device (1) comprising a flashlight (2) and a holder (3) that detachably supports the flashlight (2).

(B) The holder (3) includes a housing (4) that supports the flashlight (2),
The housing (4)
(B1) A seismic part (5) which takes a reference position when there is no earthquake motion and moves from the reference position in response to the earthquake motion;
(B2) When the movement amount of the seismic sensing part (5) reaches a predetermined amount, holding means (20, 26) for holding the seismic sensing part (5) in an operating position away from the reference position;
(B3) It has a pair of electrically insulated terminals (49, 50), and the pair of terminals (49, 50)
In a state where the flashlight (2) is supported by the holder (3), the holder (3) is interposed in a part of the electric circuit (58),
In a state where the seismic sensing part (5) is located at a place other than the operating position, a part of the electric circuit (58) is cut off to prohibit the supply of electricity from the battery (55, 56) to the light bulb (53). And
Supply of electricity from the battery (55, 56) to the light bulb (53) via the contact part (36) provided in the seismic sensing part (5) with the seismic sensing part (5) in the operating position. And a contact mechanism (6).

  According to the present invention, it is possible to automatically turn on the flashlight by detecting the shaking of the earthquake without using any power including the outside and inside of the flashlight. Therefore, the flashlight can be disposed in a place that is easy for the user to use. In addition, the flashlight battery will not be consumed in the normal state before the earthquake. As a result, it is possible to improve convenience, and thus safety during an earthquake.

  In addition, when an earthquake shake is detected, the light is turned on regardless of the occurrence of a power failure. For this reason, the light of the flashlight that lights up whenever an earthquake with a seismic intensity of a certain level or more occurs can ensure the light at the time of the earthquake. In addition, by automatically turning on, the location of the flashlight is clarified, and the flashlight can be easily found. Therefore, it becomes possible to improve the safety at the time of an earthquake.

[2: Flashlight]
As shown in FIG. 5, the flashlight 2 has a hollow cylindrical casing 51 in the same manner as a general flashlight. A spring 52 made of a conductive material is fixed to one end side in the casing 51 (upper part in FIG. 5), and the light bulb 53 and the periphery thereof are arranged on the other end side in the casing 51 (lower part in FIG. 5). A mortar-shaped reflector 54 is disposed, and two batteries 55 and 56 are disposed between the spring 52 and the light bulb 53, and one of the spring 52, the batteries 55 and 56, and the light bulb 53 is urged by the urging force of the spring 52. Are connected in series. In addition, the casing 51 is provided with an electrical wiring 57 that electrically connects the spring 52 and the other terminal of the light bulb 53, and thereby, a series circuit (electrical connection) connecting the spring 52, the batteries 55, 56, and the light bulb 53. Circuit) 58 is formed. In the present embodiment, unlike an ordinary flashlight, an on / off switch is not provided in the middle of the wiring 57. Therefore, with the batteries 55 and 56 attached, current is supplied to the light bulb 53 and the light bulb 53 is lit. However, although not shown, a switch may be provided in the middle of the electrical wiring 57 so that lighting and extinguishing can be switched by this switch.

  As a feature, the casing 51 of the flashlight 2 of the present embodiment is formed with an opening groove 60 extending in the circumferential direction on a cross section including the contact portions 59 of the two batteries 55 and 56. The size of the opening groove 60 is set such that the protrusion 47 of the contact ring 43 protruding from the housing 4 of the holder 3 can be inserted into the casing 51 through the opening groove 60.

  Although not shown, it is preferable that the casing 51 of the flashlight 2 has a structure that can be divided into two on the plane including the central axis, like the housing 4 of the holder 3. In this case, like the slot 13 of the housing 4, half of the opening groove 60 is formed in one half, and the other half is formed in the other half. When these two halves are connected, It is preferable that an opening groove is formed on the surface.

[B: Assembly]
An example of assembly of the automatic lighting device 1 having the above configuration will be described. First, as shown in FIG. 1, the contact mechanism 6 is disposed between the upper and lower annular projections 12 of one housing half 11 constituting the housing 4 of the holder 3. At this time, the protrusion 47 of the contact ring 43 is fitted into the half of the slot. Next, as shown in the drawing, a sphere 29, a stop ring 32, and a weight 26 are attached to the shaft 25 to which the alignment member 33 and the contact portion 36 are fixed, and the shaft portion below the alignment member 33 is placed inside the contact mechanism 6. The shaft portion between the spherical body 29 and the alignment member 33 is positioned in the half of the through hole of the housing upper lid 8. And the other housing half part 11 is combined with the housing half part 11 which assembled | attached the contact mechanism 6 grade | etc.,. Naturally, the combined two housing halves 11 are appropriately connected using a connecting method. Various connection methods are conceivable. For example, a plurality of holes are formed in one housing half portion 11, and a plurality of protrusions that fit into the holes are formed in the other housing half portion 11, and these protrusions are formed. The two housing halves 11 are connected by fitting them in the corresponding holes. Finally, the lower lid 9 having the annular ring 20 is fitted to the bottom of the housing 4.

  As shown in FIGS. 1 and 2, a protective lid 61 may be provided on the housing upper lid 8. In this case, it is preferable that a hole 62 having a hemispherical inner surface slightly larger than the upper half of the sphere 29 is formed in the center of the protective lid 61 and the upper portion of the sphere 29 is accommodated therein.

  When assembling the flashlight 2, the spring 52, the light bulb 53, and the reflector 54 are assembled to one half of the casing formed in half. At this time, a lens 63 may be disposed at the end of the housing 4 close to the light bulb 53. Two batteries 55 and 56 are accommodated in series between the spring 52 and the light bulb 53, and a series closed circuit 58 is formed together with the electrical wiring 57. Finally, the other casing half is assembled to one casing half that houses a battery or the like, and the two casing halves are appropriately connected by a connecting method. For example, an engaging groove and an engaging protrusion extending in the axial direction are formed in one casing half and the other casing half, respectively, and the engaging groove and the engaging protrusion are slidably engaged, The other casing half may be slid and connected to the other casing half.

  The casing 51 does not need to have the above-described split structure, and the casing end portion to which the spring 52 is attached is constituted by a single member, and a female screw is formed on the inner periphery of the casing end portion, and the remaining casing body 48 You may make it combine these casing edge parts with a casing main body by forming a male screw in the corresponding edge part, and screwing the female screw of a casing edge part with the male screw of a casing main body. In this case, the electric circuit 58 may be configured in a state in which a part of the electric wiring is formed at the joint between the female screw portion and the male screw portion and the casing end portion is combined with the casing body.

  As shown in FIG. 5, the holder 3 and the flashlight 2 configured as described above are combined by inserting the protrusion 47 protruding from the housing 4 of the holder 3 into the casing opening groove 60 of the flashlight 2. The protrusion 47 inserted from the casing opening groove 60 enters the contact part 59 of the two batteries 55.56 as shown in the figure, and the terminal of one battery 55 (upper in the figure) is connected to one of the contact rings 43. The contact terminal 49 comes into contact with the other terminal (the lower side in the figure) of the battery 56 that contacts the other contact terminal 50 of the contact ring 43. However, since the contact terminals 49 and 50 are electrically separated, the electric circuit 58 of the flashlight 2 is attached to the holder 3 by the contact ring 43 interposed in a part thereof. The current supply from the batteries 55 and 56 to the light bulb 53 is cut off, and the flashlight 2 is turned off.

  As described above, the contact ring 43 and the protrusion 47 function as a function of supporting the flashlight 2 on the holder 3 and as a contact mechanism that interrupts the electric circuit 58 of the flashlight 2 mounted on the holder 3.

  In addition, although the example which assembles the housing 4 of the holder 3 by combining the housing half parts 11 divided | segmented into the vertical direction was demonstrated, the division | segmentation method of the housing 4 of the holder 3 is not restricted to this. For example, the housing 4 of the holder 3 may be divided on the surface passing through the slot 13. In this case, preferably, the upper housing and the lower housing are screwed to each other by screws provided at the lower end portion and the upper end portion thereof.

[C: Operation]
The automatic lighting device 1 combined as described above is placed on a stable place (for example, a floor) of a building (for example, a house). In this state, the shaft 25 of the vibration sensing unit 5 takes a reference position along the axis 10 of the housing 4. When the shaft 25 is in the reference position, the lower conductive ring 42 and the upper conductive ring 44 are insulated from each other as described above, and thus the flashlight 2 is turned off. Although the automatic lighting device 1 does not need to be fixed to the floor, the holder 3 may be fixed to the floor using a double-sided adhesive tape or the like.

  In the event of an earthquake, the flashlight automatic lighting device 1 operates with the horizontal movement of the building. In particular, during the initial horizontal movement, the holder 3 and the flashlight 2 operate along with the movement of the floor. However, the seismic sensing unit 5 (shaft 25) supported at the upper end is horizontal with the holder 3 only at the upper end. Moving. Thereafter, the shaft 25 starts swinging with a unique natural period. When the swing amount (movement amount) reaches a predetermined amount, the seismic sensing unit 5 takes an operating position, and as shown in FIG. 26 is magnetically attracted to the surrounding annular ring 20, and the contact portion 36 (particularly the conductive outer member 37) in the middle stage of the shaft 25 contacts the conductive rings 42 and 44 of the contact mechanism 6. Thus, the annular ring 20 and the weight 26 function as means for holding the seismic sensing unit 5 in the operating position. Therefore, although both the annular ring 20 and the weight 26 need not be formed of magnets, at least one of them needs to be a magnet.

  As described above, the conductive rings 42 and 44 can be slightly moved in the horizontal direction, and the inner member 38 of the contact portion 36 is formed of a soft member, so that the shaft 25 is in the operating position. In addition, the conductive outer member 37 reliably contacts both the upper and lower conductive rings 42 and 44, and the upper and lower conductive rings 42 and 44 are electrically connected. As a result, the circuit 58 of the flashlight 2 interrupted by the protrusion 47 is closed via the contact terminals 49 and 50, the conductive rings 42 and 44, and the contact portion 36 (particularly, the outer member 37). The As a result, current flows from the batteries 55 and 56 to the light bulb 53, and the light bulb 53 is lit.

  Therefore, although not limited to night, even if the surroundings are dark and the earthquake is damaged, the surroundings of the flashlight automatic lighting device 1 are illuminated by the flashlight 2 that is lit in response to the earthquake. As a result, a person moving in the dark can easily recognize the location of the flashlight 2 and can safely approach the flashlight. When the flashlight 2 is removed from the holder 3, the contact portion 59 between the batteries 55 and 56 is closed, the electric circuit 58 is closed, and the light bulb 53 is lit. Therefore, the victim can move in the dark with the lit flashlight 2.

  In order to secure the electrical connection between the contact portion 36 and the conductive rings 42, 44, the contact portion 36 is pressed against the two conductive rings 42, 44 while the weight 26 is magnetically attracted to the annular ring 20. In addition, it is preferable to determine the sizes of the contact portion 36, the weight 26, the annular ring 20, and the conductive rings 42 and 44.

  In order to separate the weight 26 from the annular ring 20, the shaft 25 is pulled up with the stop ring 32 at the upper end of the shaft. Thereby, the weight 26 is easily separated from the annular ring 20 while sliding on the surface of the annular ring 20. Further, the upper surface 34 of the alignment member 33 is pressed against the upper lid lower surface 35. As a result, the shaft 25 is aligned with the axis 10 of the housing 4. As described above, according to the configuration of the present embodiment, the shaft 25 of the vibration sensing unit 5 is rearranged to the reference position only by holding the stop ring 32 at the upper end of the shaft and the shaft 25 is rearranged. Can be made extremely easy.

[D: Other forms]
7 and 8 show a second embodiment of the present invention. In this embodiment, the protrusion 65 protruding from the outer periphery of the housing of the holder 3 is bent approximately 90 degrees upward in the middle thereof. Similarly to the first embodiment, contact terminals 49 and 50 (omitted in FIGS. 7 and 8) are fixed to both surfaces of the protrusion 65. On the other hand, the casing 51 of the flashlight 2 is formed with a protrusion insertion hole 66 that opens downward. A pair of plate-like contact plates 67 are provided inside the protrusion insertion holes 66. The pair of contact plates 67 constitutes a part of an electric circuit (closed circuit) 58 in contact with each other in a state where the protrusion 65 is not inserted. In addition, in FIG. 7, the line shown with a dotted line is a half line of a casing.

  In the second embodiment configured as described above, when the flashlight 2 is assembled to the holder 3, the projection of the holder 3 is inserted into the projection insertion hole 66 while moving the flashlight 2 in the direction shown in FIG. 65 is inserted. As a result, the protrusion 65 enters between the contact plates 67 and separates the contact plates 67 from each other. As a result, the electric circuit 58 of the flashlight 2 is closed, and the light bulb 53 is kept off. The operation at the time of the earthquake is the same as that of the first embodiment.

  In the present embodiment, as shown in the figure, guide protrusions 68 protruding from the casing 51 are formed on the casing 51 of the flashlight 2, and these guide protrusions 68 are moved in the axial direction along the outer surface of the holder casing 51. Thus, it is preferable that the protrusion 65 is reliably inserted into the protrusion insertion hole 66. Further, as shown in FIG. 9, in order to prevent the protrusion 65 from coming into contact with the flashlight 2 and being damaged, a protective wall 69 is provided around the holder housing 4 except for the tip side of the protrusion 65. Is preferred.

  FIG. 10 shows a third embodiment of the present invention. In this embodiment, the protrusion 47 is inclined obliquely upward, thereby making it difficult for the flashlight 2 to fall and broadening the irradiation range by the flashlight 2. Since the flashlight 2 into which such a protrusion 47 is inserted is inclined, the flashlight 2 is supported by a flashlight support portion 71 provided in the housing.

  FIG. 11 shows a fourth embodiment of the present invention. In this embodiment, a lower conductive ring 142 and an upper conductive ring 144 are attached to the lower surface and the upper surface of the main body, respectively above and below the ring portion 46 of the central contact ring 43 (similar to the contact terminals 49 and 50 in FIG. 4). ) It is integrally fixed by, for example, brazing so as to be electrically connected to the contact terminal. The contact mechanism of the present embodiment comprising the central contact ring 43, the lower conductive ring 142, and the upper conductive ring 44 is formed from below by an annular protrusion 112 that extends continuously or intermittently along the inner circumferential direction of the housing 4. Supported. Thus, the lower fixing ring 41 and the upper fixing ring 45, which are necessary for installing the contact mechanism 6 in the housing 4 in the first embodiment, and the upper stage of the annular protrusion 12 are not necessary in the present embodiment. The configuration of the contact mechanism and the housing 4 can be simplified, and as a result, it can be easily assembled.

  FIG. 12 shows a fifth embodiment of the present invention. In this embodiment, the contact mechanism includes an auxiliary ring 145 made of an annular conductive member placed on the upper conductive ring 144 in addition to the contact mechanism of the fourth embodiment. As shown in the figure, the auxiliary ring 145 has an inner diameter slightly larger than the outer diameter of the contact portion 36, does not hinder the contact portion 36 from coming into contact with the inside of the lower and upper conductive rings 142 and 144, and the shaft 25 Regardless of the movement, it has an outer diameter capable of maintaining a state in which the upper conductive ring 144 is always in contact. Thereby, even when the shaft 25 is slightly swung, the contact portion 36 and the upper conductive ring 144 are reliably electrically connected. Therefore, when the shaft 25 swings and the contact portion 36 comes into contact with the lower conductive ring 142, the lower and upper conductive rings 142 and 144 are connected even if the contact portion 36 is inclined along the shaft 25. It can be electrically connected, and the light bulb 53 of the flashlight 2 can be lit more reliably when an earthquake occurs.

  The embodiments described so far may be combined as long as they do not contradict each other.

  As is clear from the above description, according to the automatic lighting device, the holder, and the flashlight according to the present invention, the shaft 25 of the seismic sensing unit 5 swings in response to the earthquake, and the flashlight 2 is attached to the holder 3. It automatically lights up when worn, and can illuminate a safe evacuation route for the victim even in a dark environment.

  Moreover, since the automatic lighting device 1 according to the present invention does not use a commercial power source to turn on the flashlight 2 and closes the lighting circuit (electric circuit) using seismic motion as energy, the power is supplied by the earthquake. Regardless of whether it is shut off, the flashlight can be turned on reliably in the event of an earthquake.
