Description

[Technical field]

[0001] The present invention relates to Fish-catching aid light-emitting device The present invention relates to a switch in which an operated portion is provided on the outside of a housing. [Background technology]

[0002] Conventionally, a fish-attracting light 301 as shown in Fig. 17 is known. The fish-attracting light 301 has 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] 17(a), the closed space 309 is formed by screwing together the female threaded portion of the upper member 303 and the male threaded portion of the lower member 305. A seal member 317 such as an O-ring is provided at the joint between the upper member 303 and the lower member 305. A light emitting unit 311, a battery (power source) 313, and a control board 315 are provided in the closed space 309 of the housing 307.

[0004] 17(a), the female thread of the upper member 303 and the male thread of the lower member 305 are completely screwed together (completely screwed). As a result, the seal member 317 is sandwiched between the annular end face 319 of the upper member 303 and the annular end face 321 of the lower member 305, preventing water and the like from entering the closed space 309 of the housing 307. In addition, in the state shown in FIG. 17(a), the light emitting unit 311 emits light (lights up, blinks, etc.) by the power supplied from the battery 313.

[0005] 17(b), the female threaded portion of upper member 303 and the male threaded portion of lower member 305 are in the middle of being screwed together. This causes annular end surface 319 of upper member 303 to be separated from seal member 317. Also, in the state shown in FIG. 17(b), control board 315 is separated from the terminal of battery 313, so that no power is supplied from battery 313 and light-emitting portion 311 is turned off.

[0006] That is, in the conventional fish-attracting light 301, the power supply to the fish-attracting light 301 is turned on and off by appropriately rotating the upper member 303 relative to the lower member 305, and the light-emitting part 311 is turned on and off.

[0007] Here, for example, Patent Document 1 is cited as a document relating to the prior art. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2000-4741 A Summary of the Invention [Problem to be solved by the invention]

[0009] Incidentally, in the conventional fish-attracting light 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 a 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 not used in a state where it functions as a float in the state shown in Figure 17(b), as long as waterproofing is ensured in the state shown in Figure 17(a) and water, etc. can be prevented from entering the closed space 309 of the housing 307, it would seem that no particular problems would arise.

[0011] However, in actual use of the fish-attracting light 301, it is often the case that the fish-attracting light 301 in the state shown in Fig. 17(a) is pulled out of the water, and with a small amount of water on the outer surface of the casing 307, the power supply to the fish-attracting light 301 is turned off in the state shown in Fig. 17(b). This causes a problem that water or the like may enter the closed space 309 of the casing 307.

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

[0013] The present invention has been made in consideration of the above problems, and is capable of ensuring waterproofing of the closed space of the housing even when the light-emitting mode (light-emitting pattern including on and off) of the light-emitting unit is changed.

[0022] [First embodiment] The waterproof light-emitting device 1 according to the first embodiment of the present invention is configured to include a housing 3, a switch (waterproof switch) 5, a power source installation section 7, a light-emitting section 9, and a control section 11, as shown in Figures 1 to 9.

[0023] For example, a light emitting device for assisting in catching fish can be used as the waterproof light emitting device 1. Furthermore, a fish attracting light (electric fish attracting light; fish attracting light) or a light emitting float (electric float) can be used as a light emitting device for assisting in catching fish.

[0024] A fish-attracting light is a light used to attract fish during night fishing. It is submerged in water to attract the target fish and the plankton that serves as food for these fish, making it easier to catch the target fish.

[0025] Luminous floats are mainly used for night fishing, and are attached to the middle of the fishing line to keep the hook at a constant depth and to see fish bites by its movement. Examples of luminous floats include those attached to fishing nets and floated on the water surface to find the location of the net underwater, those that float on the water surface to measure the direction and speed of the water current, and those that float on the surface of liquid in a tank or the like to find the remaining amount of liquid. Figures 1 to 9 show a fish-attracting light as a waterproof luminous device 1.

[0026] In the housing 3, a closed space (closed space surrounded and closed by the flesh) 13 is formed inside this flesh 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 flesh 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.

[0027] The power source installation unit 7 is provided in the closed space 13 of the housing 3. A power source (for example, a cell or a battery) 17 is installed in the power source installation unit 7. Naturally, the battery 17 installed in the power source installation unit 7 is also provided in the closed space 13 of the housing 3.

[0028] The light-emitting unit 9 is also provided in the closed space 13 of the housing 3. The light-emitting unit 9 emits light using power supplied from a battery 17 provided in the power source installation 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 operated unit 15.

[0029] Incidentally, whether the operated portion 15 is operated by a person or not, the airtightness of the closed space 13 of the housing 3 is ensured. In other words, regardless of whether the operated portion 15 is operated or not, the closed space 13 of the housing 3 is closed and the waterproofness of the closed space 13 of the housing 3 is maintained.

[0030] The light-emitting pattern of the light-emitting unit 9 may include, in addition to a change in the light-emitting color of the light-emitting unit 9 and a blinking pattern of the light-emitting unit 9, continuous turning off of the light-emitting unit 9, continuous lighting of the light-emitting unit 9 in one color, and the intensity (luminosity) of the light emitted by the light-emitting unit 9. The continuous turning off of the light-emitting unit 9 makes it appear that the power supply of the waterproof light-emitting device 1 is turned off. The reason for using the expression "the power supply of the waterproof light-emitting device 1 appears to be turned off" instead of "the power supply of the waterproof light-emitting device 1 is turned off" is that even if the light-emitting unit 9 appears to be turned off continuously, the magnetic sensor 19 actually detects the magnetic force of the magnet 21 at a predetermined short time interval. The details of the magnetic sensor 19 and the magnet 21 will be described later. In the state where "the power supply of the waterproof light-emitting device 1 appears to be turned off", the waterproof light-emitting device 1 consumes a very small amount of power.

[0031] The switch 5 is configured with a switch component 23 that engages with the housing 3 outside the closed space 13 of the housing 3 so as to be movable or rotatable relative to the housing 3. The operated portion 15 of the switch 5 is configured as a part of the switch component 23. In the waterproof light-emitting device 1 shown in FIGS. 1 to 9, the switch component 23 is rotatable relative to the housing 3.

[0032] The switch component 23 is formed in an annular (for example, circular) shape. The switch component 23 is engaged with the housing 3 so as to rotate about the central axis of the ring.

[0033] Furthermore, the switch 5 is configured to include an elastic body (e.g., a compression coil spring) 25 (see Figs. 15 and 16). Note that the illustration of the compression coil spring 25 is omitted in Figs. 1 to 9. When the operated portion 15 is not operated (when no force is applied to the operated portion 15), the biasing force of the compression coil spring 25 moves the switch component 23 to the initial position (operated position; reference position) shown in Fig. 1.

[0034] When the operated portion 15 is operated (when a force that generates a predetermined rotational moment of the operated portion 15 is applied), the compression coil spring 25 is compressed and elastically deformed, and the switch component 23 rotates to the operating position relative to the housing 3. The rotation direction of the switch component 23 at this time is shown by an arrow in FIG.

[0035] When the operation on the operated portion 15 is stopped (when the specified force applied to the operated portion 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.

[0036] The housing 3 is configured to include a first member (upper member) 27 and a second member (lower member) 29. The lower member 29 is integrally installed with the upper member 27 to form the housing 3 (closed space 13). The switch component 23 engages only with the upper member 27.

[0037] The switch 5 further includes a magnet (for example, a permanent magnet) 21 and a magnetic sensor 19. This makes the switch 5 a so-called magnetic switch. The magnet 21 is, for example, embedded in the switch component 23, and is thus provided integrally with the switch component 23. The magnet 21 is also located outside the closed space 13 of the housing 3 together with the switch component 23.

[0038] The magnetic sensor 19 is provided in the closed space 13 of the housing 3, and detects the magnetic force of the magnet 21 that passes through the flesh of the housing 3. The magnetic sensor 19 is composed of a coil, a Hall element, or the like.

[0039] When the switch component 23 rotates relative to the housing 3, the position of the magnet 21 relative to the magnetic sensor 19 changes, so that the magnetic sensor 19 detects the magnetic force of the magnet 21 or the magnetic sensor 19 does not detect the magnetic force of the magnet 21.

[0040] The control unit 11 is adapted to change the light emission pattern of the light emitting unit 9 in accordance with whether the magnetic sensor 19 detects or does not detect a magnetic force.

[0041] Here, the waterproof light-emitting device 1 will be described in more detail.

[0042] The lower member 29 of the housing 3 is made of, for example, synthetic resin and is formed in a tall bowl shape (a long and narrow bowl shape in which the height dimension is greater than the inner diameter dimension and the outer diameter dimension). A female thread portion 31 and a seal material abutment portion 33 are formed at the upper end of the inner surface of the lower member 29. The seal material abutment portion 33 is located above the female thread portion 31. The upper end surface of the lower member 29 (the end surface at the opening) forms a seal material abutment portion 35 separate from the seal material abutment portion 33.

[0043] The upper member 27 of the housing 3 is configured to include 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 through which the light emitted by the light emitting unit 9 passes.

[0044] The inner member 37 is configured to include a cylindrical inner tube portion 41 with a bottom, a first flange portion 43, a cylindrical outer tube portion 45, and a second flange portion 47. The inner tube portion 41 has a bottom plate portion located on the upper side and an opening portion located on the lower side.

[0045] The first flange 43 is provided at the lower end of the inner cylinder 41 and extends outward from the opening of the inner cylinder 41. The outer cylinder 45 rises upward from the outer periphery of the first flange 43. The height dimension of the outer cylinder 45 is smaller than the height dimension of the inner cylinder 41.

[0046] The second flange portion 47 is provided at the upper end of the outer tubular portion 45 and extends outward from the opening of the outer tubular portion 45 .

[0047] A male thread portion 49, a first seal material mounting portion 51, and a second seal material mounting portion 53 are formed on the outer surface of the outer tube portion 45. The first seal material mounting portion 51 is located above the male thread portion 49, and the second seal material mounting portion 53 is located above the first seal material mounting portion 51. The lower surface of the second flange portion 47 forms a seal material abutment portion 55.

[0048] The female thread portion 31 of the lower member 29 and the male thread portion 49 of the inner member 37 of the upper member 27 screw together, so that the lower member 29 and the inner member 37 are integrated together, and a closed space 13 is formed between the inner member 37 and the lower member 29.

[0049] The waterproof light-emitting device 1 is also provided with an annular first sealant 57 and an annular second sealant 59. The first sealant 57 is installed in the first sealant installation portion 51 and abuts against the sealant abutment portion 33 of the lower member 29. The second sealant 59 is installed in the second sealant installation portion 53 and abuts against the sealant abutment portion 35 of the lower member 29 and the sealant abutment portion 55 of the inner member 37.

[0050] The seal members 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 seal members 57 and 59 are formed of, for example, O-rings.

[0051] The outer portion of the outer member 39 is formed in a cylindrical shape with a diameter that gradually decreases toward the upper side. Also, the upper portion of the inner tube portion 41 of the inner member 37 fits inside the cylindrical inner portion of the outer member 39, so that the outer member 39 is integrated with the inner member 37, and the cylindrical inner portion of the outer member 39 covers the upper portion of the inner tube 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.

[0052] When the inner member 37 and outer member 39 of the upper member 27 are installed on the lower member 29, a ring-shaped switch component installation portion 61 is formed on the outside (outer periphery) of the inner tube 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.

[0053] The switch component 23 mounted on the switch component mounting portion 61 is adapted to rotate relative to the housing 3, with the central axis of the housing 3 serving as the center of rotation. The central axis of the housing 3 and the central axis of the annular switch component 23 coincide with each other. The switch component 23 is made of, for example, synthetic resin.

[0054] The operated portion 15 is configured, for example, by a protrusion formed on a part of the outer periphery of an annular switch component 23. The outer shape of the housing 3 in which the switch component 23 is installed is spheroidal (prolate spheroidal).

[0055] The power source installation section (battery installation section) 7 is provided inside the lower member 29, i.e., in a lower portion of the closed space 13. The light emitting section 9 is composed of, for example, a plurality of LEDs, and is disposed inside the inner cylinder section 41 at an upper portion of the inner cylinder section 41 of the inner member 37. Light emitted by the light emitting section 9 passes through the inner cylinder section 41 and the outer member 39 and comes out to the outside of the housing 3.

[0056] The magnet 21 is embedded in a part of the circumference of the annular switch component 23. The magnetic sensor 19 is disposed inside the inner cylindrical portion 41 of the inner member 37 (closed space 13).

[0057] When the operated part 15 is not operated, the magnetic sensor 19 detects the magnetic force of the magnet 21, and when the operated part 15 is operated, the magnetic sensor 19 does not detect the magnetic force of the magnet 21.

[0058] In addition, when the operated part 15 is not operated, the magnetic sensor 19 may not detect the magnetic force of the magnet 21, and when the operated part 15 is operated, the magnetic sensor 19 may detect the magnetic force of the magnet 21.

[0059] 1 to 9 as described above, the compression coil spring 25 is installed at the switch component installation portion 61 with its central axis bent in an arc shape as shown in Fig. 15 and Fig. 16. One end of the compression coil spring 25 abuts against a spring abutment portion (not shown) of the inner cylinder portion 41 of the inner member 37, and the other end of the compression coil spring 25 abuts against a spring abutment portion (not shown) of the switch component 23. As a result, when the switch component 23 rotates with respect to the housing 3, the above-mentioned biasing force is generated.

[0060] The control unit 11 is provided on a board (control board) 65 that is installed in the closed space 13 below the inner cylindrical portion 41 of the upper member 27.

[0061] Next, the operation of the waterproof light-emitting device 1 will be described.

[0062] In the initial state, the power supply of the waterproof light emitting device 1 is turned off (the power supply of the waterproof light emitting device 1 appears to be turned off).

[0063] In the above initial state, the switch component 23 is rotated from the reference position in the direction shown by the arrow in Fig. 1 etc. for a predetermined time t1, and then returned to the reference position to turn on the power of the waterproof light-emitting device 1. In this state, the light-emitting unit 9 emits light in, for example, a predetermined color.

[0064] Next, the switch component 23 is rotated from the reference position in the direction shown by the arrow in Fig. 1 etc. for a predetermined time t2, and then returned to the reference position, changing the light emission pattern of the waterproof light-emitting device 1 (blinking or changing color). For example, the time t2 is shorter than the time t1.

[0065] When the waterproof light emitting device 1 is to be turned off, the switch component 23 is rotated from the reference position in the direction shown by the arrow in FIG. 1 etc. for a predetermined time t1, and then returned to the reference position.

[0066] The waterproof light-emitting device 1 is composed of a housing 3 in which a closed space 13 is formed, a switch 5 provided on the housing 3 so that the operated part 15 is located outside the closed space 13 of the housing 3, a power source installation part 7 provided in the closed space 13 of the housing 3 and in which a battery 17 is installed, a light-emitting part 9 that emits light using power supplied from the battery 17 provided in the power source installation part 7 provided in the closed space 13 of the housing 3, and a control part 11 that changes the light emission pattern of the light-emitting part 9 in response to the operation of the switch 5 on the operated part 15.

[0067] As a result, even if the operated part 15 is operated, the airtightness of the closed space 13 of the housing 3 is ensured, and even if the light emission mode of the light emitting part 9 (light emission pattern including on and off) is changed, the waterproofness of the closed space 13 of the housing 3 is not compromised, and water, etc. are prevented from entering the closed space 13 of the housing 3.

[0068] Moreover, in the waterproof light-emitting device 1, the switch 5 is configured to include a switch component 23 that is engaged with the housing 3 outside the closed space 13 of the housing 3 so as to be rotatable relative to the housing 3, and the operated portion 15 of the switch 5 is configured as a part of the switch component 23. This ensures that 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.

[0069] In addition, in the waterproof light-emitting device 1, the switch component 23 is formed in an annular shape, and the switch component 23 engages with the housing 3 so as to rotate around the central axis of the ring. This simplifies the installation structure of the switch component 23 in the housing 3, and further improves the operability of the operated part 15.

[0070] In addition, in the waterproof light-emitting device 1, the switch 5 is configured to include a compression coil spring 25, and in a state where the operated part 15 is not operated, the switch component 23 is configured to be in an initial position by the biasing force of the compression coil spring 25. This makes it possible to reliably keep the light-emitting part 9 of the waterproof light-emitting device 1 turned off.

[0071] That is, the switch component 23 does not easily move from the initial position due to the biasing force of the compression coil spring 25. If the light emitting part 9 of the waterproof light emitting device 1 is turned off when the switch component 23 is in the initial position, this turned off state can be reliably maintained.

[0072] For example, even if the waterproof light-emitting device 1 with the light-emitting unit 9 turned off is stored in a case (not shown) or a bag, the switch component 23 is reliably maintained in the initial position, so that the light-emitting unit 9 will not emit light inside the case for some reason and the light-emitting unit 9 will not continue to be lit, which would waste the battery 17.

[0073] In contrast, with a conventional fish-attracting light 301, when the fish-attracting light 301 is stored in a case or the like in the state shown in FIG. 20(b), the upper member 303 may rotate relative to the lower member 305 for some reason, resulting in the state shown in FIG. 20(a), and the light-emitting part 311 may continue to emit light unnecessarily.

[0074] Moreover, in the waterproof light-emitting device 1, the housing 3 is configured to include an upper member 27 and a lower member 29, and the lower member 29 is integrally installed with the upper member 27 to form the housing 3 (closed space 13), and the switch component 23 engages with the upper member 27. As a result, the switch component 23 is installed 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 simple configuration.

[0075] Furthermore, in the waterproof light emitting device 1, the switch 5 is configured to include a magnet 21 provided in the switch component 23, and a magnetic sensor 19 that is provided in the closed space 13 of the housing 3 and detects the magnetic force of the magnet 21. This eliminates the need for mechanical contacts, improving the durability of the switch 5.

[0076] In the above description, the compression coil spring 25 is used to assist the rotation of the switch component 23 and change the illumination pattern of the light-emitting unit 9. However, the illumination pattern of the light-emitting unit 9 may be changed by making the switch component 23 perform a latch-type operation.

[0077] The latch-type 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 operating position. This operation is performed, for example, by using a ball plunger to push the switch component 23 in the operated position and by using another ball plunger to push the switch component 23 in the operating position.

[0078] Furthermore, the switch 5 may be a push-button type waterproof switch.

[0079] Second Embodiment The waterproof luminous device 1a according to the second embodiment of the present invention has a different shape from the waterproof luminous device 1 according to the first embodiment of the present invention, but is generally configured in the same manner as the waterproof luminous device 1 according to the first embodiment of the present invention.

[0080] Similar to the waterproof light-emitting device 1, the waterproof light-emitting device 1a is also configured to include a housing 3, a switch (waterproof switch) 5, a power source installation section 7, a light-emitting section 9, and a control section 11 (see Figs. 10 to 16). Note that the same reference numerals are used in Figs. 10 to 16 to designate components similar to those of the waterproof light-emitting device 1 shown in Figs. 1 to 9.

[0081] In the waterproof light emitting tool 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 part 61 is configured by the upper member 27 and the lower member 29. That is, the switch component installation part 61 is formed at the joint between the upper member 27 and the lower member 29.

[0082] Moreover, 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.

[0083] Third embodiment The waterproof light emitting device 1b according to the third embodiment of the present invention is different 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 is otherwise configured similarly to the waterproof light emitting devices 1 and 1a. The housing 3 is configured with a cover member 71 and an outer skin of the light emitting device main body 79.

[0084] To explain further, the cover member 71 of the waterproof light-emitting device 1b is detachable from the light-emitting device main body 79. Also, the cover member 71 is provided with a guide portion (long, thin guide groove) 85 as shown in FIG. 17. The switch component 73 is engaged with and guided by the guide portion 85, and is capable of moving linearly a predetermined distance relative to the housing 3. That is, the switch component 73 is capable of moving linearly upward from the state shown in FIG. 17 or FIG. 18 until it abuts against a stopper 77. The stopper 77 is provided integrally with the cover member 71.

[0085] A magnet 83 (see FIG. 19) is provided integrally with the switch component 73. An elastic body (compression coil spring) 75 biases the switch component 73 downward. A magnetic sensor 87 is provided integrally with the light emitting device main body 79. A light emitting section (e.g., an LED) 81 is also provided integrally with the light emitting device main body 79. The cover member 71 is configured to transmit at least a portion of the light emitted by the light emitting section 81.

[0086] When the switch component 73 moves relative to the housing 3, the position of the magnet 83 relative to the magnetic sensor 87 changes, so that the magnetic sensor 87 detects the magnetic force of the magnet 83 or the magnetic sensor 87 does not detect the magnetic force of the magnet 83.
