Description

Technical Field

[0001] The present invention relates to a light-emitting device for assisting in catching fish, and relates to one in which an operating portion of a switch is provided outside a housing.

Background Art

[0002] Conventionally, a fish-aggregating light 301 as shown in FIG. 17 has been known. The fish-aggregating light 301 includes a housing 307 composed of an upper member 303 and a lower member 305. A closed space 309 is formed inside the housing 307.

[0003] As shown in FIG. 17(a), the closed space 309 is formed by screwing the female screw portion of the upper member 303 and the male screw portion of the lower member 305 together. Also, a seal member 317 such as an O-ring is provided at the joint portion between the upper member 303 and the lower member 305. In the closed space 309 of the housing 307, a light-emitting portion 311, a battery (power source) 313, and a control board 315 are provided.

[0004] In the state shown in FIG. (a), the female screw portion of the upper member 303 and the male screw portion of the lower member 305 are completely screwed together (in a completely screwed state). As a result, the seal member 317 is sandwiched between the annular end surface 319 of the upper member 303 and the annular end surface 321 of the lower member 305, so that water or the like does not enter the closed space 309 of the housing 307. Also, in the state shown in FIG. 17(a), the light-emitting portion 311 emits light (lights up or blinks, etc.) by the power supplied from the battery 313.

[0005] On the other hand, in the state shown in FIG. 17(b), the female screw portion of the upper member 303 and the male screw portion of the lower member 305 are in a state of being screwed together halfway. As a result, the annular end surface 319 of the upper member 303 is separated from the seal member 317. Also, in the state shown in FIG. 17(b), the control board 315 is separated from the terminals of the battery 313, and the power supply from the battery 313 is not performed, so that the light-emitting portion 311 is turned off.

[0006] In other words, in the conventional fish-attracting light 301, the power to the fish-attracting light 301 is turned on and off by appropriately rotating the upper member 303 relative to the lower member 305, causing the light-emitting part 311 to illuminate and then turn off.

[0007] Here, as an example of prior art literature, we cite Patent Document 1. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Japanese Patent Publication No. 2000-4741 [Overview of the project] [Problems that the invention aims to solve]

[0009] By the way, in conventional fish-attracting lights 301, when the power is turned off, as shown in Figure 17(b), the annular end face 319 of the upper member 303 separates from the sealing member 317, and there is a risk that water or the like may enter the closed space 309 of the housing 307 through the small gap between the threads of the female screw portion of the upper member 303 and the threads of the male screw portion of the lower member 305.

[0010] Furthermore, since the fish-attracting light 301 is never used in a state where it functions as a float as shown in Figure 17(b), it seems that no particular problems will occur as long as waterproofing is ensured in the state shown in Figure 17(a) and water and other substances can be prevented from entering the enclosed space 309 of the housing 307.

[0011] However, in actual use of the fish-attracting light 301, it is common to remove the fish-attracting light 301 from the water when it is in the state shown in Figure 17(a), and then turn off the power to the fish-attracting light 301 when it is in the state shown in Figure 17(b) with some water still on the outside of the housing 307. This presents a problem in that water may enter the enclosed space 309 of the housing 307.

[0012] The above problem occurs not only when turning the power on and off, but also when changing the light emission pattern of the light-emitting unit 311. The change in the light emission pattern of the light-emitting unit 311 is achieved by appropriately repeating the states shown in Figure 17(a) and Figure 17(b).

[0013] The present invention has been made in view of the above-mentioned problems, and aims to provide a waterproof light-emitting device that can ensure the waterproofness of the enclosed space of the housing even when the light-emitting mode (light-emitting pattern including turning on and off) of the light-emitting part is changed. [Means for solving the problem]

Embodiments for Carrying Out the Invention

[0018] 〔First Embodiment〕 As shown in Figures 1 to 9, the waterproof light-emitting device 1 according to the first embodiment of the present invention comprises a housing 3, a switch (waterproof switch) 5, a power supply unit 7, a light-emitting unit 9, and a control unit 11.

[0019] As a waterproof luminous device 1, for example, a luminous device for assisting in the capture of fish can be displayed. Furthermore, as a luminous device for assisting in the capture of fish, a fish-attracting light (electric fish-attracting light; fish-attracting light) or a luminous float (electric float) can be displayed.

[0020] A fish-attracting light is a light used in nighttime fishing to attract fish. It is submerged in water and used to attract target fish and plankton, which are their food source, making it easier to catch the target fish.

[0021] Luminous floats are primarily used for night fishing. They are attached to the fishing line to keep the hook at a constant depth and to detect bites by observing their movement. Other types of luminous floats include those attached to fishing nets to locate the net underwater, those used to measure the direction and speed of water currents, and those used to indicate the remaining amount of liquid in tanks. Figures 1 to 9 show a fish-attracting light as waterproof luminescent device 1.

[0022] In the housing 3, a closed space (a closed space enclosed and sealed by the fleshy part) 13 is formed inside this fleshy part. The switch 5 is provided with an operated part 15. The operated part 15 is provided on the housing 3 so as to be located outside (outside) the closed space 13 of the housing 3, separated by the fleshy part of the housing 3. Also, the operated part 15 appears to form, for example, a part of the outer surface of the housing 3.

[0023] The power supply unit 7 is located in the enclosed space 13 of the housing 3. A power supply (for example, a battery) 17 is installed in the power supply unit 7. Naturally, the battery 17 installed in the power supply unit 7 is also located in the enclosed space 13 of the housing 3.

[0024] The light-emitting unit 9 is also located in the enclosed space 13 of the housing 3. The light-emitting unit 9 is powered by electricity supplied from the battery 17 located in the power supply unit 7. The control unit 11 changes the light-emitting pattern of the light-emitting unit 9 in response to the operation of the switch 5 on the operable part 15.

[0025] Furthermore, the airtightness of the enclosed space 13 of the housing 3 is ensured whether the operated part 15 is operated by a person or not. In other words, regardless of whether the operated part 15 is operated or not, the enclosed space 13 of the housing 3 remains closed, and the waterproofness of the enclosed space 13 of the housing 3 is maintained.

[0026] In addition to changes in the light color and flashing patterns of the light-emitting unit 9, the light-emitting unit 9 can also exhibit continuous off-lighting, continuous illumination in a single color, and varying light intensity (luminosity) of the light emitted by the light-emitting unit 9. The continuous off-lighting of the light-emitting unit 9 makes it appear as if the waterproof light-emitting device 1 is powered off. The reason for using the phrase "appears to be powered off" rather than "the waterproof light-emitting device 1 is powered off" is that, even though the light-emitting unit 9 appears to be continuously off, the magnetic sensor 19 is actually detecting the magnetic force of the magnet 21 at predetermined short time intervals. Details of the magnetic sensor 19 and magnet 21 will be described later. In the state where "the waterproof light-emitting device 1 appears to be powered off," the waterproof light-emitting device 1 consumes a very small amount of power.

[0027] The switch 5 is configured to include a switch component 23 that is movable or rotatable relative to the housing 3 and engages with the housing 3 outside the closed space 13 of the housing 3. The operated portion 15 of the switch 5 is made up of a part of the switch component 23. In the waterproof light-emitting device 1 shown in Figures 1 to 9, the switch component 23 is rotatable relative to the housing 3.

[0028] The switch component 23 is formed in an annular shape (for example, a ring shape). The switch component 23 is engaged with the housing 3 so as to rotate around the central axis of this ring as the pivot point.

[0029] Furthermore, the switch 5 is configured to include an elastic body (for example, a compression coil spring) 25 (see Figures 15 and 16). Note that the compression coil spring 25 is not shown in Figures 1 to 9. When the operated part 15 is not being operated (when no force is being applied to the operated part 15), the biasing force of the compression coil spring 25 causes the switch component 23 to move to the initial position (operated position; reference position) shown in Figure 1.

[0030] When the operated part 15 is operated (when a force is applied that generates a predetermined rotational moment on the operated part 15), the compression coil spring 25 is compressed and elastically deformed, causing the switch component 23 to rotate relative to the housing 3 to the operating position. The direction of rotation of the switch component 23 at this time is indicated by the arrow in Figure 1.

[0031] When the operation on the operated part 15 is stopped (when the predetermined force applied to the operated part 15 is removed), the switch component 23 is configured to return to its initial position due to the biasing force (restoring force) of the compression coil spring 25.

[0032] The housing 3 is composed of a first member (upper member) 27 and a second member (lower member) 29. The housing 3 (closed space 13) is formed when the lower member 29 is integrally installed on the upper member 27. The switch component 23 engages only with the upper member 27.

[0033] The switch 5 is further equipped with a magnet (for example, a permanent magnet) 21 and a magnetic sensor 19. Thus, the switch 5 is a so-called magnetic switch. The magnet 21 is integrally provided with the switch component 23, for example, by being embedded in it. The magnet 21, along with the switch component 23, is located outside the enclosed space 13 of the housing 3.

[0034] The magnetic sensor 19 is located in the enclosed space 13 of the housing 3 and is designed to detect the magnetic force of the magnet 21 that penetrates the material of the housing 3. The magnetic sensor 19 is composed of a coil or a Hall element, etc.

[0035] As the switch component 23 rotates relative to the housing 3, the position of the magnet 21 relative to the magnetic sensor 19 changes, causing the magnetic sensor 19 to either detect the magnetic force of the magnet 21 or to not detect the magnetic force of the magnet 21.

[0036] The control unit 11 changes the light emission pattern of the light emission unit 9 depending on whether the magnetic sensor 19 detects or does not detect magnetic force.

[0037] Here, we will explain the waterproof light-emitting device 1 in more detail.

[0038] The lower member 29 of the housing 3 is made of synthetic resin, for example, and is formed in a tall, bowl-like shape (a long, narrow bowl-like shape in which the height dimension is greater than the inner diameter and outer diameter dimensions). A female threaded portion 31 and a sealant contact portion 33 are formed at the upper end of the inner surface of the lower member 29. The sealant contact portion 33 is located above the female threaded portion 31. The upper end surface of the lower member 29 (the end surface at the opening) is a separate sealant contact portion 35 from the sealant contact portion 33.

[0039] The upper member 27 of the housing 3 is composed of an inner member 37 and an outer member 39. The inner member 37 and the outer member 39 are made of a synthetic resin or the like that allows light emitted from the light-emitting unit 9 to pass through.

[0040] The inner member 37 is composed of a bottomed cylindrical inner cylinder portion 41, a first flange portion 43, a cylindrical outer cylinder portion 45, and a second flange portion 47. The inner cylinder portion 41 has a bottom plate portion on the upper side and an opening on the lower side.

[0041] The first flange portion 43 is provided at the lower end of the inner cylinder portion 41 and extends outward from the opening of the inner cylinder portion 41. The outer cylinder portion 45 rises upward from the outer circumference of the first flange portion 43. The height dimension of the outer cylinder portion 45 is smaller than the height dimension of the inner cylinder portion 41.

[0042] The second flange portion 47 is provided at the upper end of the outer cylinder portion 45 and extends outward from the opening of the outer cylinder portion 45.

[0043] The outer surface of the outer cylinder portion 45 has a male screw portion 49, a first seal material installation portion 51, and a second seal material installation portion 53. The first seal material installation portion 51 is located above the male screw portion 49, and the second seal material installation portion 53 is located above the first seal material installation portion 51. The lower surface of the second flange portion 47 is a seal material contact portion 55.

[0044] The female threaded portion 31 of the lower member 29 and the male threaded portion 49 of the inner member 37 of the upper member 27 are threaded together, causing the lower member 29 and the inner member 37 to become one, and a closed space 13 to be formed between the inner member 37 and the lower member 29.

[0045] Furthermore, the waterproof light-emitting device 1 is provided with an annular first seal material 57 and an annular second seal material 59. The first seal material 57 is installed in the first seal material installation portion 51 and is in contact with the seal material contact portion 33 of the lower member 29. The second seal material 59 is installed in the second seal material installation portion 53 and is in contact with the seal material contact portion 35 of the lower member 29 and the seal material contact portion 55 of the inner member 37.

[0046] The sealing materials 57 and 59 provide a double seal at the joint between the lower member 29 and the inner member 37 of the upper member 27. The sealing materials 57 and 59 are made of, for example, O-rings.

[0047] The outer portion of the outer member 39 is formed in a cylindrical shape, with the diameter gradually decreasing as it moves upwards. Furthermore, the upper portion of the inner cylindrical portion 41 of the inner member 37 fits inside the cylindrical inner portion of the outer member 39, thus integrating the outer member 39 with the inner member 37, and the cylindrical inner portion of the outer member 39 covers the upper portion of the inner cylindrical portion 41 of the inner member 37. The outer portion and the inner portion of the outer member 39 are joined to each other at their upper ends.

[0048] When the inner member 37 and outer member 39 of the upper member 27 are installed on the lower member 29, an annular switch component installation portion 61 is formed on the outer side (outer circumference) of the inner cylinder portion 41, between the upper end (upper surface) of the second flange portion 47 of the inner member 37 and the lower end (lower surface) of the outer member 39.

[0049] The switch component 23, installed in the switch component mounting section 61, rotates relative to the housing 3 with the housing 3's central axis as its pivot point. The central axis of the housing 3 and the central axis of the annular switch component 23 coincide. The switch component 23 is made of, for example, synthetic resin.

[0050] The operated portion 15 is, for example, a protrusion formed on a part of the outer circumference of an annular switch component 23. The outer shape of the housing 3 in which the switch component 23 is installed is a spheroid (elongated sphere).

[0051] The power supply unit (battery unit) 7 is located inside the lower member 29, that is, in the lower part of the enclosed space 13. The light-emitting unit 9 is composed of, for example, multiple LEDs and is located inside the inner cylinder 41 in the upper part of the inner cylinder 41 of the inner member 37. The light emitted by the light-emitting unit 9 passes through the inner cylinder 41 and the outer member 39 and comes out to the outside of the housing 3.

[0052] The magnet 21 is embedded in the annular switch component 23 at a portion of its circumference. The magnetic sensor 19 is installed inside the inner cylinder portion 41 of the inner member 37 (closed space 13).

[0053] Furthermore, when the operated part 15 is not being operated, the magnetic sensor 19 detects the magnetic force of the magnet 21, and when the operated part 15 is being operated, the magnetic sensor 19 does not detect the magnetic force of the magnet 21.

[0054] Furthermore, the magnetic sensor 19 may not detect the magnetic force of the magnet 21 when the operated part 15 is not being operated, and the magnetic sensor 19 may detect the magnetic force of the magnet 21 when the operated part 15 is being operated.

[0055] As mentioned above, the compression coil spring 25 is not shown in Figures 1 to 9, but as shown in Figures 15 and 16, it is installed at the switch component mounting portion 61 with its central axis bent in an arc shape. One end of the compression coil spring 25 is in contact with the spring contact portion (not shown) of the inner cylinder portion 41 of the inner member 37, and the other end of the compression coil spring 25 is in contact with the spring contact portion (not shown) of the switch component 23. This generates the biasing force described above when the switch component 23 rotates relative to the housing 3.

[0056] The control unit 11 is located on a circuit board (control board) 65 which is installed in a closed space 13 below the inner cylindrical portion 41 of the upper member 27.

[0057] Next, the operation of the waterproof light-emitting device 1 will be explained.

[0058] In the initial state, the power to the waterproof light-emitting device 1 is turned off (or appears to be turned off).

[0059] In the initial state described above, the switch component 23 is rotated from the reference position in the direction indicated by the arrow in Figure 1, etc., for a predetermined time t1, and then returned to the reference position, thereby turning on the power to the waterproof light-emitting device 1. In this state, the light-emitting part 9 emits light in a predetermined color, for example.

[0060] Next, the switch component 23 is rotated from the reference position in the direction indicated by the arrow in Figure 1, etc., for a predetermined time t2. After this, it is returned to the reference position, which changes the light emission pattern of the waterproof light-emitting device 1 (it flashes or changes color). For example, time t2 is shorter than time t1.

[0061] To turn off the power to the waterproof light-emitting device 1, rotate the switch component 23 from the reference position in the direction indicated by the arrow in Figure 1, etc., for a predetermined time t1, and then return it to the reference position.

[0062] The waterproof light-emitting device 1 comprises a housing 3 in which a closed space 13 is formed, a switch 5 provided on the housing 3 such that the operated part 15 is located outside the closed space 13 of the housing 3, a power supply unit 7 provided on the closed space 13 of the housing 3 where a battery 17 is installed, a light-emitting unit 9 provided on the closed space 13 of the housing 3 and which emits light using power supplied from the battery 17 provided on the power supply unit 7, and a control unit 11 which changes the light-emitting pattern of the light-emitting unit 9 in response to the operation of the operated part 15 of the switch 5.

[0063] As a result, even when the operated part 15 is operated, the airtightness of the enclosed space 13 of the housing 3 is ensured, and even when the light emission mode (including lighting and extinguishing patterns) of the light emission unit 9 is changed, the waterproofness of the enclosed space 13 of the housing 3 is not compromised, and water or other substances are prevented from entering the enclosed space 13 of the housing 3.

[0064] Furthermore, in the waterproof light-emitting device 1, the switch 5 is configured to include a switch component 23 that is rotatably engaged with the housing 3 on the outside of the closed space 13 of the housing 3, and the operated portion 15 of the switch 5 is made up of a part of the switch component 23. As a result, the switch component 23 (the operated portion 15 of the switch 5) is reliably separated from the closed space 13 of the housing 3, and the waterproofness of the closed space 13 of the housing 3 can be ensured with a simple configuration.

[0065] Furthermore, in the waterproof light-emitting device 1, the switch component 23 is formed in an annular shape, and the switch component 23 is engaged with the housing 3 so as to rotate around the central axis of this ring as the pivot point. This simplifies the installation structure of the switch component 23 to the housing 3 and further improves the operability of the operated part 15.

[0066] Furthermore, in the waterproof light-emitting device 1, the switch 5 is configured to include a compression coil spring 25, and when the operated part 15 is not being operated, the biasing force of the compression coil spring 25 causes the switch component 23 to return to its initial position. This ensures that the light-emitting part 9 of the waterproof light-emitting device 1 is reliably turned off.

[0067] In other words, the biasing force of the compression coil spring 25 prevents the switch component 23 from easily moving from its initial position. Furthermore, if the light-emitting part 9 of the waterproof light-emitting device 1 is off when the switch component 23 is in its initial position, this off state can be reliably maintained.

[0068] For example, even if the waterproof light-emitting device 1 with the light-emitting part 9 turned off is stored in a case (not shown) or bag, the switch component 23 is reliably maintained in its initial position, preventing the light-emitting part 9 from emitting light inside the case due to some factor, and preventing the battery 17 from being wasted.

[0069] In contrast, with conventional fish-attracting lights 301, if the fish-attracting light 301 is housed in a case or the like in the state shown in Figure 20(b), the upper member 303 may rotate relative to the lower member 305 due to some factor, resulting in the state shown in Figure 20(a), and the light-emitting part 311 may continue to emit light unnecessarily.

[0070] Furthermore, in the waterproof light-emitting device 1, the housing 3 is composed of an upper member 27 and a lower member 29, and the housing 3 (closed space 13) is formed when the lower member 29 is integrally installed on the upper member 27, and the switch component 23 engages with the upper member 27. As a result, the switch component 23 is installed while avoiding the area where the upper member 27 and the lower member 29 engage with each other, and the waterproofness of the closed space 13 of the housing 3 can be more reliably ensured with a simpler configuration.

[0071] Furthermore, in the waterproof light-emitting device 1, the switch 5 is configured to include a magnet 21 provided on the switch component 23 and a magnetic sensor 19 provided in the closed space 13 of the housing 3 for detecting the magnetic force of the magnet 21. As a result, there are no mechanical contacts, and the durability of the switch 5 is improved.

[0072] By the way, in the above explanation, a compression coil spring 25 is used to assist the rotation of the switch component 23 and change the light emission pattern of the light emission unit 9. However, the light emission pattern of the light emission unit 9 may also be changed by making the switch component 23 perform a latching action.

[0073] A latching operation is an operation in which the switch component 23 can maintain its position when it is in the operated position (reference position), and can also maintain its position when it is in the operated position. This operation is performed, for example, by using a ball plunger to push the switch component 23 in the operated position, and then using another ball plunger to push the switch component 23 in the operated position.

[0074] Furthermore, a push-button type waterproof switch may be used as switch 5.

[0075] [Second Embodiment] The waterproof light-emitting device 1a according to the second embodiment of the present invention has a different shape from the waterproof light-emitting device 1 according to the first embodiment of the present invention, but is generally configured in the same manner as the waterproof light-emitting device 1 according to the first embodiment of the present invention.

[0076] The waterproof light-emitting device 1a, like the waterproof light-emitting device 1, is configured to include a housing 3, a switch (waterproof switch) 5, a power supply unit 7, a light-emitting unit 9, and a control unit 11 (see Figures 10 to 16). Components configured similarly to the waterproof light-emitting device 1 shown in Figures 1 to 9 are also denoted by the same reference numerals in Figures 10 to 16.

[0077] In the waterproof light-emitting device 1a according to the second embodiment of the present invention, the housing 3 is configured to include an upper member 27 and a lower member 29, and the switch component installation portion 61 is composed of the upper member 27 and the lower member 29. That is, the switch component installation portion 61 is formed at the joint between the upper member 27 and the lower member 29.

[0078] Furthermore, in the waterproof light-emitting device 1a, a weight 63 is provided inside the lower member 29, and a battery 17 is provided in the center of the upper member 27.

[0079] [Third Embodiment] The waterproof light-emitting device 1b according to the third embodiment of the present invention differs from the waterproof light-emitting devices 1 and 1a in that the switch component 73 of the switch 5 is engaged with the housing 3 so as to be movable (linearly movable) relative to the housing 3, but in other respects it is configured the same as the waterproof light-emitting devices 1 and 1a. The housing 3 is composed of a cover member 71 and an outer shell of the light-emitting device body 79.

[0080] To further explain, the cover member 71 of the waterproof light-emitting device 1b is detachably attached to the light-emitting device body 79. Furthermore, the cover member 71 is provided with a guide portion (a long, narrow guide groove) 85, as shown in Figure 17. The switch component 73 engages with the guide portion 85 and is guided, allowing it to move linearly a predetermined distance relative to the housing 3. That is, the switch component 73 can move linearly upward from the state shown in Figures 17 and 18 until it contacts the stopper 77. The stopper 77 is integrally provided with the cover member 71.

[0081] A magnet 83 (see Figure 19) is integrally provided on the switch component 73. An elastic body (compression coil spring) 75 biases the switch component 73 downward. A magnetic sensor 87 is integrally provided on the light-emitting device body 79. A light-emitting part (for example, an LED) 81 is also integrally provided on the light-emitting device body 79. The cover member 71 is designed to transmit at least a portion of the light emitted by the light-emitting part 81.

[0082] As the switch component 73 moves relative to the housing 3, the position of the magnet 83 relative to the magnetic sensor 87 changes, causing the magnetic sensor 87 to either detect the magnetic force of the magnet 83 or to stop detecting the magnetic force of the magnet 83.
