Description

Technical Field

[0001] This invention relates to a fishing reel that winds fishing line onto a spool via a handle. Background Technology

[0002] Previously, as a fishing reel, a double-bearing type reel was known, in which the spool was rotatably supported between the side plates of the reel body. This double-bearing type reel included a device with a counter display function, which showed the amount of fishing line released (water depth) when the clutch mechanism was OFF (disengaged) and the spool was in a free-rotating state. Typically, the amount of fishing line released was calculated by pre-installing a magnet on the side of the spool, using a magnetic sensor mounted on the reel body to detect the magnet and the amount of spool rotation, and then calculating the amount of line released according to a prescribed procedure.

[0003] In the aforementioned dual-bearing type cable reel, in addition to detecting the rotation of the drum, there are also cases where the movement of the working parts needs to be detected, and new functions are desired. In this case, a detection unit (various sensors) is needed to detect the displacement of the working parts. However, if the detection unit is installed inside the side plate on the handle side, it will hinder the miniaturization of the cable reel body. In particular, recent hand-cranked dual-bearing type cable reels have been sought to be miniaturized, but because the side plate on the handle side contains a power transmission mechanism and a force release mechanism, which transmits the driving force from the drive gear mounted on the handle shaft, there are space limitations, making it difficult to install the detection unit and achieve miniaturization.

[0004] Furthermore, in this invention, as described later, it is planned to provide a detection unit (also called a clutch sensor) for detecting the ON (on) / OFF (off) state of the clutch. However, in the past, there was no technical concept of installing such a clutch sensor on hand-cranked dual-bearing cable reels (dual-bearing cable reels intended to be miniaturized).

[0005] In existing dual-bearing type cable reels, methods exist for detecting the ON / OFF state of the clutch by detecting the movement of the clutch operating component. Regarding the clutch operating component, a configuration is known where it is movable vertically between the left and right side plates behind the drum (see, for example, Patent Documents 1 and 2). The clutch operating component disclosed in Patent Document 1 has protrusions formed on both sides of the clutch operating component, which is connected to the clutch mechanism on one side, and these protrusions are guided and supported vertically in elongated holes formed on the left and right frames. Furthermore, the clutch operating component disclosed in Patent Document 2 is a so-called single-sided support structure connected to the clutch mechanism on one side.

[0006] Patent documents

[0007] Patent Document 1: Japanese Patent Publication No. 3-16087

[0008] Patent Document 2: Japanese Utility Model Registration No. 2594912 Summary of the Invention

[0009] Because the clutch operating components disclosed in Patent Documents 1 and 2 are not designed as precision support structures, they are prone to loosening and deformation. Therefore, when detecting the displacement of the clutch operating components, stable detection capability cannot be ensured, and there is a possibility of false detection. Furthermore, in the pursuit of miniaturization, there was originally no concept of incorporating a clutch sensor for detecting the movement of the clutch operating components in hand-cranked, dual-bearing cable reels. Moreover, in the prior art, there is no configuration that avoids increasing the size of the cable reel body and includes a detection unit on the side plate opposite the handle, which is used to reliably detect the ON / OFF operation of the clutch.

[0010] The present invention addresses the aforementioned problems, and the technical problem to be solved is to provide a fishing reel with a clutch sensor that does not increase the size of the reel body and can detect the ON / OFF operation of a stable clutch.

[0011] To achieve the above objectives, the fishing reel of the present invention is characterized by comprising: a drum rotatably supported between two side plates disposed on the left and right sides of the reel body; a handle for rotating and driving the drum; a battery compartment disposed within the side plates on the side plate opposite to the handle, and housing a replaceable battery; a clutch mechanism having a clutch operating member for switching the drum between a free-rotation state and a line winding state; a holding member movable integrally with the clutch operating member and holding the detected part; and a detection sensor disposed inside the battery compartment for detecting the moving detected part and determining whether the clutch mechanism is in an ON or OFF state. Furthermore, the holding member engages with a guide portion formed around the battery compartment, and the detected part is guided by the guide portion together with the holding member as the clutch operating member moves.

[0012] In the above configuration, when the clutch operating component moves with the ON / OFF state of the clutch mechanism, the detected part, held on the retaining component, moves integrally. A detection sensor located inside the battery compartment detects this movement and determines whether the clutch mechanism is in the ON or OFF state. Because the retaining component engages with a guide portion formed around the battery compartment, and the detected part moves along with the retaining component when the clutch operating component moves, the movement of the detected part is stable, thus ensuring stable detection capability for the detection sensor.

[0013] According to the present invention, a fishing reel capable of detecting the ON / OFF action of a stable clutch can be obtained. Attached Figure Description

Detailed Implementation

[0023] Hereinafter, with reference to the accompanying drawings, embodiments of the fishing reel, namely the hand-cranked double-bearing type reel (hereinafter referred to as the reel), according to the present invention will be described.

[0024] Figure 1 This is a top view showing one implementation of a cable reel. Figure 2 This is a side view taken from the side opposite the handle, and then... Figure 3 It means from Figure 2 The diagram shows the state after the cover component has been removed.

[0025] The cable reel 1 according to this embodiment has a cable reel body 1A having a left side plate 4A and a right side plate 4B, which are mounted on left and right frames. Figure 3 The diagram shows left and right covers 3a and 3b on the left frame 2), which are integrated by multiple supports as is known. Furthermore, a reel foot 5 for mounting to a reel seat on a fishing rod is integrally formed between the left and right frames.

[0026] A spool shaft is rotatably supported by bearings between two side plates (left side plate 4A and right side plate 4B) located on the left and right sides of the reel body 1A. A spool 7 for winding fishing line is fixed on the spool shaft. In this embodiment, the spool 7 is driven to rotate by a known winding drive mechanism provided in the right side plate by rotating the handle 8 provided on the right side plate 4B.

[0027] Furthermore, a known drag mechanism 12 is provided on the right side plate 4B. This drag mechanism 12 applies drag to the reel 7 when the fishing line is released from the reel 7 during fishing. The drag mechanism 12 includes: multiple braking components that engage with the side of the drive gear of a reel drive mechanism rotatably mounted on the handle shaft; and a braking force adjusting body (also called a star-shaped drag wheel) 13 that applies pressure to the braking components. The braking force adjusting body 13 is configured to rotate relative to the handle shaft on the reel body side near the handle 8. By rotating the braking force adjusting body 13, pressure can be applied to the braking components, and the frictional force (drag) of the drive gear relative to the handle shaft can be adjusted.

[0028] The winding drive mechanism includes a drive gear rotatably mounted on the handle shaft and a pinion meshing with the drive gear, and has the function of transmitting the rotation of the handle shaft to the drum 7 through the pressure relief mechanism 12, the drive gear, and the pinion. In addition, the pinion can move axially upward through the operation of a known clutch mechanism provided in the right side plate, and switch between the power transmission state (clutch ON) and the power cut-off state (clutch OFF) by engaging and disengaging relative to the drum shaft.

[0029] The clutch mechanism includes a clutch operating member 15 disposed on the rear side of the drum 7, between the left side plate 4A and the right side plate 4B. When the clutch operating member 15 is pressed, the drum 7 enters a clutch OFF state, allowing free forward and reverse rotation. Furthermore, in this state, by performing a winding operation on the handle 8, the clutch can be switched to ON state via a known automatic return mechanism, allowing the fishing line to be wound onto the drum 7 directly by performing a winding operation on the handle 8.

[0030] Furthermore, an information display device (IC counter) 20 with a display section 20a is provided on the upper side of the drum 7 between the left side plate 4A and the right side plate 4B of the reel body 1A. This information display device 20 also functions as a thumb rest. The display section 20a displays various information, such as the length of line released from the drum when the clutch is OFF (detecting the rotation of the drum 7), the depth of the fish, and the time. Additionally, an operation button 20b is provided on the information display device 20 so that the user can input various settings (in...). Figure 1 There is one operation button set up, but multiple buttons can also be set.

[0031] The line length information (line release length, release speed, etc.) mentioned above can be calculated based on the detection signals from the detection sensors of the rotation amount and direction of rotation of the detection reel 7, according to a prescribed calculation procedure. On the inner side of the left side plate 4A opposite the handle, there are components of a control device for controlling various information, including a detection sensor, a control board for processing the detection signals from the detection sensor, a cable for transmitting and receiving signals from the control board to the information display device 20, and a power supply (battery box) for operating them.

[0032] Furthermore, in this invention, the hand-cranked double-bearing reel with IC counter function described above detects not only the rotation of the reel 7 but also the operation of the clutch operating component 15 of the clutch mechanism, thus adding a new function. Specifically, in this embodiment, it includes a function that, when the drag mechanism is in operation, announces the rotation state of the reel 7 in the direction of releasing the fishing line with sound. At this time, the rotation of the reel 7 in the direction of releasing the fishing line may occur when the reel 7 is freely rotating in the clutch OFF state, or when a fish is caught in the clutch ON state, the drag mechanism is activated, and the reel 7 rotates. In this embodiment, the detection is performed when the reel 7 is in the clutch ON state, and in this state, an announcement is made when the reel 7 rotates in the direction of releasing the fishing line.

[0033] That is, it is configured to detect the position of the clutch operating component 15, determine the clutch ON state and the clutch OFF state, and when the spool rotates in the direction of releasing the fishing line in the clutch ON state, it can report the rotation with sound.

[0034] While a detection device (hereinafter also referred to as a clutch sensor) that performs the functions described above can be provided in conjunction with the clutch mechanism located on the inner side of the right side plate 4B on the handle side, the inner side of the right side plate 4B on the handle side is equipped with a winding drive mechanism, a release mechanism, an automatic recovery mechanism, etc., as described above. Therefore, if a detection device is provided here, it would result in a large-scale winding reel body. In particular, in hand-cranked double-bearing winding reels like this embodiment, and further in small hand-operated electric winding reels, there is a requirement to minimize the size of the winding reel body as much as possible. Therefore, for the detection device, it is preferable to configure it to obtain efficient and stable detection results.

[0035] In this embodiment, the clutch sensor is efficiently mounted using the battery box 30 located on the left side plate 4A opposite to the handle, while a stable detection action can be obtained.

[0036] The following is for reference Figures 3 to 6 The configuration of the clutch sensor in this embodiment will be described.

[0037] Figure 3 The left side plate 4A opposite to the handle is shown, and it is shown that there is a... Figure 2 The state shown is the state after the left cover 3a has been removed.

[0038] On the left side panel 4A, a battery compartment 30 is provided to power the information display device 20. The battery compartment 30 is configured to hold a battery (button battery; see reference) of the same size as a Japanese 500 yen coin (approximately 25-26 mm in diameter). Figure 6The device comprises: a first body 30A, which is generally cylindrical; a second body 30B, which is integrated with the first body 30A and fixed to the frame 2 of the cable reel body; and a cover member 30C that closes the opening of the first body 30A. A control board (circuit board) 50, which is generally circular, is used to match the shape of the battery box, and the central portion of the control board (circuit board) 50 is fixed to the second body 30B by a fixing screw 50a. Furthermore, a cable 51 is connected to the control board 50, which has the function of transmitting and receiving signals to the information display device 20 and supplying power to the information display device.

[0039] Thus, the battery box 30 of this embodiment is formed with an outer peripheral surface having a roughly circular cross-section, and is fixed to the frame 2 on the inner side of the left side plate 4A.

[0040] In addition, such as Figure 6 As shown, the battery box 30 is provided with O-rings (sealing components) 32a and 32b between the first body 30A and the second body 30B and between the first body 30A and the cover component 30C, and the receiving part 30S inside the battery box is waterproofed.

[0041] The battery box 30 is fixed to the frame 2 by a predetermined fixing structure. In this embodiment, a fixing piece 31 protruding radially is pre-formed on the first body 30A (or the second body 30B) and fixed to the fixing part 2a provided on the frame 2. The battery box 30 is fixed, for example, by screwing a screw 31a into the fixing part 2a, and two fixing structures of this embodiment are provided at approximately 180° intervals (see reference). Figure 3 ).

[0042] like Figure 2 As shown, the cover component 30C is approximately flush with the left cover 3a and protrudes to the side, with an elongated groove 30a formed on its surface. Therefore, when the battery is depleted, the user can insert a coin or similar object into the elongated groove 30a to remove the cover component 30C and replace it with a new battery.

[0043] On the aforementioned battery compartment 30, a clutch sensor 40 capable of detecting the ON and OFF operations of the clutch mechanism is provided. In this embodiment, the clutch sensor 40 is configured to detect the ON / OFF operation of the clutch operating member 15, and is configured to detect the OFF state when the clutch operating member 15 is pressed down from the initial position and the ON state when the clutch operating member 15 is returned to the initial position. Furthermore, the clutch sensor 40 of this embodiment includes: a detection part (magnet 41) provided on the displacement side; and a detection sensor (Hall element 42) provided on the battery compartment 30 side, which detects changes in the magnetic field of the displaced magnet 41, thus using a simple magnetic sensor.

[0044] The clutch operating component 15 is configured to move vertically between the left and right frames on the rear side of the drum 7. Figures 3 to 6 The left frame 2, which is the side opposite to the handle, is shown. The end 15a of the clutch operating member 15 is held vertically within an elongated hole 2b formed on the frame 2. Similarly to the left frame 2, the other end of the clutch operating member 15 is also held vertically within an elongated hole formed on the right frame (not shown), thereby enabling the clutch operating member 15 to move stably up and down.

[0045] The end portion 15a of the clutch operating member 15 passes through the elongated hole 2b and is connected to the retaining member 45, on which the magnet 41 is provided, through the protruding portion of the elongated hole 2b. Specifically, the retaining member 45 of this embodiment includes a retaining body 45A with the magnet 41 built in it and an engaging portion 45B, described later. The end portion 15a of the clutch operating member 15 is fitted into a forked protrusion 45a formed on the retaining body 45A. Therefore, when the clutch operating member 15 moves in the vertical direction by the ON / OFF operation of the clutch, the retaining member 45 can move integrally.

[0046] Furthermore, the retaining member 45 engages with a guide portion formed around the battery compartment 30 to stably guide the aforementioned movement of the retaining member 45. In this embodiment, the retaining member 45 and the guide portion are in a concave-convex engagement state, and the retaining member 45 is configured to move in this state. Specifically, the guide portion is formed by a groove 46, which is formed in a circular (or arc-shaped) shape along the outer peripheral surface of the battery compartment 30 on the exposed side of the frame 2. An annular (or C-shaped) guide plate 45B is integrally formed on the retaining member 45 to engage (fit) with the groove 46 (see reference). Figures 4 to 6 ).

[0047] Furthermore, in the above configuration, it is preferable to use a fixing piece 31 provided on the battery box 30 to prevent the guide plate 45B from detaching in the axial direction (see reference). Figure 3Furthermore, it is preferable to pre-set a clearance at the connection between the clutch operating member 15 and the retaining member 45 (retaining body 45A). For example, a small clearance may also be provided at the engagement between the end 15a of the clutch operating member 15 and the forked protrusion 45a formed on the retaining body 45A.

[0048] On the left side plate 4A, a drum sensor 60 is provided for detecting the rotational speed (rotation amount) and rotational direction of the drum 7. This drum sensor 60 is also associated with the battery box 30. In this embodiment, the drum sensor 60 includes a reed switch 61 that is opened and closed by a change in magnetic field. Three reed switches 61 are arranged circumferentially along the side of the drum 7. In addition, the drum sensor 60 includes a detected part (magnet 62) detected by the reed switch 61. The magnet 62 is held in a magnet holding member 7A fixed to the side surface 7a of the drum 7 (or the magnet 62 can be directly fixed to the side surface 7a of the drum 7).

[0049] A reed switch 61, arranged circumferentially, is mounted on the back side (frame side) of a control board 50 fixed within the battery compartment 30. A clutch sensor, i.e., a detection sensor 42, is mounted on the surface side (left cover 3a side) of the control board 50. That is, the clutch sensor 40 and the drum sensor 60 are respectively mounted on opposite sides of the control board 50, which is housed within a pre-waterproofed battery compartment 30. This eliminates the need for waterproofing the sensors and simplifies and compacts the detection sensor design.

[0050] Figure 7 This diagram shows the positional relationship between the control board 50, clutch sensor 40, and drum sensor 60 located inside the battery box 30. It is a schematic diagram viewed from the drum side.

[0051] In this embodiment, as described above, both the clutch sensor 40 and the drum sensor 60 are magnetic sensors that detect changes in the magnetic field. Therefore, in the configuration where these sensors are placed within the battery compartment 30, the placement of the two sensors needs to be considered. In this embodiment, interference from the magnetic field is suppressed by placing the detection sensors 42 and 61 on both sides of the control board 50, which is sealed and housed within the battery compartment. Furthermore, by placing the detection sensors 42 and 61 on both sides within the range of the control board, rather than on the outside of the control board 50, they can be efficiently housed within the battery compartment.

[0052] At this point, if the control substrate 50 has a thicker wall, it will not be affected by the magnetic fields of the magnets 41 and 62, so the placement of each detection sensor 42 and 61 is not particularly restricted. However, if the control substrate 50 has a thinner wall, the magnetic fields of the magnets 41 and 62 may interfere with each other. Figure 7 As shown, it is preferable that the detection sensors 42 and 61 are arranged so that they do not overlap in the axial direction.

[0053] In this embodiment, the clutch sensor 40 is used, for example, to emit a sound (drag sound) when the drum sensor 60 detects rotation in the direction of the fishing line release, after determining that the clutch mechanism is in the ON state. For example, when the clutch mechanism is in the ON state, the angler can monitor the drag mechanism slipping and releasing the fishing line when a fish is caught. Furthermore, the sound in this state can be adjusted in volume and tone according to the drum's rotation speed, allowing the angler to monitor the braking state of the drag mechanism.

[0054] The fishing reel described above can achieve the following effects.

[0055] Because the clutch sensor 40 is located on the left side plate 4A opposite to the handle, rather than on the right side plate 4B on the handle side, the reel body is not enlarged, and space can be used efficiently. In particular, new functions can be implemented in hand-cranked, double-bearing type reels or small, handheld electric reels without increasing the size of the reel body.

[0056] Furthermore, by utilizing the internal space of the battery compartment 30 to house the detection sensor 42, a waterproofing measure can be achieved using the sealed structure of the battery compartment 30, eliminating the need for a separate waterproofing structure on the detection sensor. This simplifies the structure and enables miniaturization. At this point, using a magnetic sensor as the detection sensor further simplifies the structure and allows for efficient use of the internal space within the battery compartment 30.

[0057] Furthermore, when the clutch operating member 15 moves with the ON / OFF operation of the clutch mechanism, the magnet 41, held on the retainer 45A of the retaining member 45, moves integrally in the vertical direction along with the movement of the clutch operating member 15. A detection sensor 42 disposed within the battery compartment 30 detects changes in the magnetic field of the magnet 41 within the retainer 45A and detects the position of the clutch operating member 15 to determine whether the clutch mechanism is in the ON or OFF state. Since the annular guide plate 45B of the retaining member 45 engages with the guide portion (groove 46), which is formed on the frame 2 along the outer peripheral surface of the battery compartment 30 body, the guide plate 45B can rotate stably, thus guiding the movement of the retainer 45A holding the magnet 41 in a stable state. Therefore, stable detection capability can be ensured.

[0058] In particular, since the guide plate 45B of the retaining member 45 rotates along the circumferential direction of the battery box in this embodiment, it can be set to maintain the same distance from the detection sensor 42, thereby enabling stable detection capability.

[0059] Furthermore, in this embodiment, the guide plate 45B is prevented from detaching axially by the fixing piece 31 provided on the battery box 30, thus preventing axial displacement of the guide plate 45B and enabling stable detection capability. Moreover, by pre-setting a clearance at the connection between the clutch operating member 15 and the retaining member 45 (retaining body 45A), any loosening that occurs during the movement of the clutch operating member can be absorbed, thereby preventing any impact on the rotation of the guide plate 45B and ensuring stable detection capability.

[0060] While the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from its spirit.

[0061] For example, although this embodiment uses a cylindrical battery box 30 and the guide portion is formed in a circular or arc shape for efficient placement, when the battery box is cubic (cubic prism) in shape, the guide portion can be appropriately deformed to fit its shape, such as extending in the vertical direction or in the front-back direction. That is, the shape of the guide portion can be appropriately deformed according to the shape of the battery and the shape of the battery box.

[0062] Furthermore, while maintaining the engagement between the retaining component (guide plate) and the guide portion, the guide method can also be appropriately modified by forming the protrusion on both sides of the frame and the recess on the guide plate side. Moreover, the detection sensor is not limited to magnetic sensors; for example, optical sensors can also be used, thus allowing for appropriate modifications.
