Description

[Technical field]

[0001] The present invention relates to a dual-bearing reel in which a spool for winding fishing line is rotatably supported between side plates of a reel body, and more particularly to a dual-bearing reel equipped with an opening and closing mechanism that allows the side plates to be attached and detached from a frame. [Background technology]

[0002] Generally, dual-bearing reels are configured with side plates attached to the left and right sides of the frame, with the spool rotatably supported between the left and right side plates. Dual-bearing reels also require the attachment and detachment of the spool and maintenance of various functional parts, so they are provided with an opening and closing mechanism that makes it possible to remove the side plates from the frame.

[0003] As an opening / closing mechanism for attaching and detaching the side plate to the frame, for example, the configuration disclosed in Patent Document 1 is known. The opening / closing mechanism disclosed in Patent Document 1 is configured such that a rotating ring that is rotatably supported on a set plate installed inside the side plate is provided, and the locked state between the frame and the side plate is released by rotating the rotating ring. The rotating ring is provided with an operating part that protrudes radially outward from the side plate (reel body), and the locked state can be released by operating this operating part in the circumferential direction.

[0004] [Patent Document 1] Patent Publication No. 2022-94071 Summary of the Invention [Problem to be solved by the invention]

[0005] In the opening and closing mechanism disclosed in the above-mentioned Patent Document 1, the rotating ring is disposed on the side plate side, which makes the side plate thicker. This makes the side plate larger and less easy to hold, leaving room for improvement in the opening and closing mechanism. Furthermore, since the rotating ring is covered by the set plate, there is also room for improvement in maintainability.

[0006] The present invention has been made in response to the above-mentioned problems, and has an object to provide a dual-bearing reel that has a smaller side plate, is easier to grip, and has an opening and closing mechanism that is easy to maintain. [Means for solving the problem]

[0007] In order to achieve the above-mentioned objective, the dual-bearing reel of the present invention has a reel body equipped with an opening and closing mechanism that enables a side plate to be opened and closed relative to a frame, and is characterized in that the opening and closing mechanism has a movable member that is displaceably supported on the frame and has an operating portion exposed from the reel body and a locking portion, and an engaging portion that is provided on the side plate and can be engaged and disengaged with the locking portion when the movable member is displaced by operating the operating portion.

[0008] In the dual-bearing reel with the above-mentioned configuration, the opening and closing mechanism for opening and closing the side plate relative to the frame has a movable member having an operating part and a locking part provided on the frame side, and an engaging part that engages with the locking part provided on the side plate side, so that the space required to incorporate the movable member into the side plate can be eliminated. This allows the side plate to be made thinner, resulting in a smaller size and improved grip. Furthermore, when the side plate is removed from the frame by the opening and closing mechanism, the movable member is exposed, improving maintainability. Effect of the Invention

[0009] According to the present invention, a dual-bearing reel can be obtained in which the side plate is made smaller and easier to grip, and which is equipped with an opening and closing mechanism that is easy to maintain. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] First, the overall configuration of one embodiment of a dual-bearing reel 1 according to the present invention will be described with reference to FIGS. 1 to 3. FIG. The reel body 1A of the dual-bearing reel 1 according to this embodiment is equipped with left and right side plates (covers) 5A, 5B attached so as to cover the sides (left and right side parts 3A, 3B) of the frame 3 which is integrally formed into a predetermined shape. The left and right side plates 5A, 5B in this embodiment are configured to have a substantially elliptical shape in a side view, and a spool 6 around which fishing line S is wound is rotatably supported between the left and right side plates.

[0012] A handle 7 for rotating the spool 6 is provided on one of the left and right side plates (on the left side plate 5A in this embodiment), and the rotational driving force of the handle 7 is transmitted to the spool 6 by a known power transmission mechanism disposed in the internal space between the left side plate 5A and the left side portion 3A of the frame 3. The handle 7 may be configured to be provided on the right side plate 5B.

[0013] Furthermore, a known level wind mechanism 9 equipped with a line guide 9a for guiding the fishing line is provided in front of the spool 6 between the left and right side plates, and the line guide 9a is driven to reciprocate left and right in front of the spool 6 via the power transmission mechanism. As a result, when the handle 7 is operated to wind the fishing line, the fishing line is evenly wound around the spool 6 via the line guide 9a, which reciprocates left and right.

[0014] The frame 3 is integrally formed with left and right side portions 3A, 3B, with a left side plate 5A attached to the left side portion 3A and a right side plate 5B attached to the right side portion 3B. The frame 3 is also formed with a connecting portion that connects the left side portion 3A and the right side portion 3B. This connecting portion may be formed in a plurality of locations, for example, on the front side, rear side, upper side, and lower side of the spool 6. These connecting portions may be covered with an exterior member such as metal, if necessary.

[0015] Of the above connecting parts, the lower connecting part provided below the spool 6 is integrally formed with the reel legs 3C to be attached to the reel seat of the fishing rod (the reel legs 3C may be formed integrally with the frame 3). In addition, the connecting part 3D above the spool 6 may function as a thumb rest on which fingers can be placed when the reel body 1A is gripped and held.

[0016] There is no limitation on the shapes of the left and right side parts 3A, 3B of the frame 3 and the left and right side plates 5A, 5B attached thereto. In this embodiment, the outer peripheral shape is configured to be a non-circular shape (approximately elliptical shape) extending in the front-rear direction in a side view (see FIG. 3). In this case, the side on which the handle 7 is provided (the left side part 3A of the frame 3 and the left side plate 5A) may have a different shape from the right side part 3B of the frame 3 and the right side plate 5B, since a drive gear is attached thereto, so that a storage space for the drive gear is secured.

[0017] Further, a circular opening (circular opening) is formed in one of the left and right side portions 3A, 3B of the frame 3 so that the spool 6 can be inserted and removed in the axial direction. In this embodiment, the right side plate 5B is structured so as to be removable from the frame 3 by the following opening and closing mechanism, and therefore the circular opening is formed in the right side portion 3B of the frame 3.

[0018] The opening and closing mechanism enables the side plate to be opened and closed (detached) relative to the frame 3 so that the spool 6 can be attached and detached and various functional parts can be maintained. In this embodiment, the right side plate 5B, which is the side opposite the handle, is configured to be detached from the right side portion 3B of the frame 3.

[0019] The opening and closing mechanism 20 of this embodiment will be described below with reference to FIGS. The opening / closing mechanism 20 has a movable member 21 that is displaceably supported on the frame 3 (right side portion 3B) and has an operating portion 21a exposed from the reel body 1A and a locking portion 21b. The movable member 21 only needs to be movably held on the frame 3, and is moved by operating the operating portion 21a. The opening / closing mechanism 20 is also provided on the right side plate 5B, and has an engaging portion 23 that can be engaged with and disengaged from the locking portion 21b when the movable member 21 is displaced by operating the operating portion 21a.

[0020] In other words, when the operating portion 21a is operated to move the movable member 21, and the engagement portion 21b and the engagement portion 23 engage with each other, the movable member 21 is locked, and when the operating portion 21a is operated to move the movable member 21, and the engagement portion 21b and the engagement portion 23 are released from each other, the movable member 21 is unlocked.

[0021] The moving member 21 is held movably along the surface of the right side portion 3B of the frame 3. In this case, the moving member 21 preferably has an arc-shaped portion so that the moving space can be efficiently utilized and the locking portion 21b and the engaging portion 23 can be engaged and disengaged in a stable state. Also, the locking portion 21b is preferably provided on the inside (diametrically inner side) of the arc-shaped portion so that the locking portion 21b and the engaging portion 23 do not become large in diameter or thick in the axial direction.

[0022] The moving member 21 of this embodiment is formed in the right side portion 3B of the frame 3, and is formed in a ring shape arranged along the periphery of a circular opening 3E through which the spool 6 is inserted (hereinafter, the moving member 21 formed in a ring shape is also referred to as an "opening / closing lever 21"). The opening 3E is formed to have approximately the same diameter as the flange of the spool 6, and in FIG. 4, the opening edge of the circular opening 3E overlaps with the inner edge 21A of the opening / closing lever 21.

[0023] A locking portion 21b is integrally formed on the radial inner side (inner edge 21A) of the opening / closing lever 21 so as to protrude toward the center. The number of the locking portions 21b is not limited, but in the configuration shown in Fig. 4, three locking portions 21b are formed at intervals of approximately 120°. Further, the operating portion 21a is integrally formed on the radially outer surface side of the opening / closing lever 21 so as to protrude radially outward.

[0024] The operation unit 21a is disposed so as to protrude from the reel body 1A and be slidable with a finger. For this reason, a notch 24 is formed in the position where the right side portion 3B of the frame 3 and the right side plate 5B face each other, and the operation unit 21a is disposed so as to protrude outward from the notch 24. In this case, the notch 24 is formed on the outer surface of the right side portion 3B of the frame, and is preferably formed in a position where it cannot be touched by a finger during normal use of the reel, for example, at the bottom end of the reel body 1A.

[0025] A set plate 30 is attached to the inside of the right side plate 5B. The set plate 30 in this embodiment is formed in a substantially cylindrical shape and is fixed to the inner surface of the side plate 5B by a screw 32 (there may be a plurality of screws). An outer peripheral surface 30a of the set plate 30 is inserted into the circular opening 3E of the frame 3 so as to be substantially flush with the outer peripheral surface of the flange of the spool 6.

[0026] A ring-shaped boss 30b for bearing support is formed in the central region of the set plate 30. A bearing 60 (see FIGS. 6(a) and 6(b)) for supporting the end of the drive shaft of the spool 6 is disposed in the internal space of the boss 30b and is held in place in the axial direction by a retaining member (not shown).

[0027] A known backlash prevention device (magnetic brake device) is held on the outer periphery of boss 30b. The backlash prevention device includes ring magnets 50 and 51 arranged concentrically. The inner ring magnet 50 is fixed to the outer periphery wall of boss 30b, and the outer ring magnet 51 is supported rotatably with respect to set plate 30.

[0028] The ring magnet 51 is supported by a support portion 53 that is rotatably supported by the set plate 30, and teeth (not shown) formed on the support portion 53 mesh with teeth 55a of an adjustment dial 55 that is rotatably supported by the set plate 30. A part of the adjustment dial 55 is exposed from the underside of the right side plate 5B, and by rotating the adjustment dial 55, the ring magnet 51 becomes rotatable due to the meshing relationship between the teeth.

[0029] Furthermore, when the right side plate 5B is attached to the right side portion 3B of the frame 3, an annular conductor (not shown) provided on one side of the spool 6 is positioned between the ring magnets 50, 51. Then, when the adjustment dial 55 is rotated in this state to change the position of the outer ring magnet 51, the magnetic flux between the ring magnets 50, 51 changes, and the magnetic force acting on the annular conductor (the braking force on the spool) is adjusted.

[0030] As described above, the set plate 30 is formed in a substantially cylindrical shape, and its outer circumferential surface 30a is formed with three engagement portions 23 which are respectively engaged with and disengaged from the three locking portions 21b of the opening / closing lever 21. Here, the locking portion 21b and the engagement portion 23, which are components of the opening / closing mechanism 20 in this embodiment, will be described. In addition to the side plate 5B shown in Fig. 5, Fig. 6 shows the positional relationship of the opening / closing lever 21 disposed around the opening 3E of the frame 3 (right side portion 3B) so as to be clearly understood.

[0031] The right side plate 5B is axially attached to the frame 3 (right side portion 3B) in an aligned state. Therefore, the position of the locking portion 21b formed on the opening / closing lever 21 is aligned with the three engaging portions 23 formed on the outer circumferential surface 30a of the set plate 30. That is, the outer circumferential surface 30a of the set plate 30 has the engaging portions 23 formed in positions corresponding to the positions into which the locking portions 21b fit.

[0032] The engagement portion 23 in this embodiment includes cutout portions 30d formed at intervals of approximately 120° on the outer peripheral surface 30a of the set plate 30, and annular grooves 30e formed on the axial outside thereof and having a groove width that allows the locking portion 21b to move circumferentially.

[0033] The operation of the opening and closing mechanism 20 configured as above will now be described. 6(a) shows the inner surface of the right side plate 5B in a state (locked state) in which the right side plate 5B is attached to the right side portion 3B of the frame 3. At this time, each locking portion 21b of the opening / closing lever 21 is fitted into the annular groove 30e of the set plate 30, and each locking portion 21b is restricted by the wall portion 30f of the annular groove 30e, and is fixed to the right side portion 3B of the frame 3 (locked state). In this manner, the locking state is ensured by each of the locking portions 21b fitting into the annular groove 30e, and the right side plate 5B will not come off.

[0034] When the operating portion 21a is pinched and moved toward the rear of the reel body from the state shown in Fig. 6(a), the locking portions 21b of the opening / closing lever 21 are positioned in the respective cutout portions 30d of the set plate 30, as shown in Fig. 6(b). At this time, the right side plate 5B is in a state in which it can be removed from the right side portion 3B of the frame 3 (unlocked state). This allows the side plate 5B to be pinched and moved in the axial direction, and the right side plate 5B can be removed from the frame 3, and the spool 6 can be removed from the opening 3E of the frame 3.

[0035] The frame 3 is preferably provided with positioning portions 3g, 3h for restricting the rotational position of the operation portion 21a of the opening / closing lever 21 (see FIG. 4). This allows the rotation of the opening / closing lever 21 to be stopped at the unlocked position where the engagement is released, and at the locked position where the engagement is maintained.

[0036] When the right side plate 5B is attached to the frame 3, the right side plate 5B is aligned with and integrated with the right side part 3B of the frame 3 when the operating part 21a of the opening / closing lever 21 is in the position shown in Fig. 6(b). In this state, the right side plate 5B can be locked by operating the operating part 21a to the position shown in Fig. 6(a).

[0037] According to the above-mentioned configuration, by providing the opening / closing lever 21 of the opening / closing mechanism 20 on the right side portion 3B of the frame 3, it is possible to eliminate the space required for incorporating the opening / closing lever into the right side plate 5B. This allows the right side plate 5B to be made thinner, resulting in a smaller size and improved grip.

[0038] In this case, as shown in Fig. 5(b), the right side plate 5B can be inclined downward from the center C in the vertical direction by a larger angle 5B2 than the inclined upward from the center by a larger angle 5B1, so that the reel body 1A can be made narrower (sharper) and easier to grip. Also, by forming the engagement portion 23 on the outer peripheral surface 30a of the set plate 30 and providing the locking portion 21b on the radially inner side of the ring-shaped opening / closing lever 21, space can be made more efficient and the reel body can be made more compact.

[0039] In addition, the opening / closing lever 21 of the opening / closing mechanism 20 is formed in a ring shape along the periphery of the opening through which the spool 6 is inserted and removed, and the operating part 21a is rotated, thereby making efficient use of space and enabling operation along an arc-shaped trajectory, thereby stabilizing the rotational movement.

[0040] Furthermore, when the right side plate 5B is removed from the right side portion 3B of the frame 3 by using the opening / closing lever 21, the opening / closing lever 21 becomes exposed, which improves maintainability.

[0041] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways. In the above-described opening / closing mechanism 20, the engaging portion 23 is provided on the outer peripheral surface of the set plate 30 of the right side plate 5B, but the right side plate 5B may be provided with an engaging portion without providing a set plate. In addition, the shape of the moving member (opening / closing lever 21) may be any shape as long as it is movably held on the frame side, and accordingly, the configuration of the locking portion 21b and the engaging portion 23 can be appropriately modified.

[0042] Also, in the above embodiment, the engagement portions and locking portions are provided in three locations, but there is no limit to the number of them provided and the lock / unlock structure, and they can be modified as appropriate depending on the shape, size, etc. of the reel body. Furthermore, in the case of a right-hand handle type dual-bearing reel, a similar opening and closing mechanism 20 can be provided on the left side plate 5A and left side portion 3A.
