Description

Technical Field

[0001] The present invention relates to a double-bearing reel that rotatably supports a spool for winding a fishing line between side plates of a reel body, and more particularly to a double-bearing reel that has an opening and closing mechanism that allows the side plates to be detachably mounted on a frame. Background Art

[0002] Generally, a double-bearing reel has side covers (side plates) mounted on the left and right sides of a frame, and the reel is rotatably supported between the left and right side plates. In addition, since it is necessary to install and remove the reel or perform maintenance on various functional parts on the double-bearing reel, an opening and closing mechanism that can remove the side cover from the frame is provided.

[0003] As an opening and closing mechanism for attaching and detaching the side cover relative to the frame, for example, there is a known structure disclosed in Patent Document 1. The opening and closing mechanism disclosed in Patent Document 1 is configured such that a rotating ring rotatably supported is provided on a mounting plate provided inside the side cover, and the locked state between the frame and the side cover can be released by rotating the rotating ring. The rotating ring is provided with an operating portion protruding radially outward from the side cover (winder body), and the locked state can be released by operating the operating portion in the circumferential direction.

[0004] Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2022-94071 Summary of the invention

[0005] Since the opening and closing mechanism disclosed in the above-mentioned patent document 1 is to arrange the rotating ring on the side of the side cover plate, the side cover plate will be thickened accordingly. Therefore, due to the enlargement of the side cover plate, the gripping property is also reduced, so there is room for improvement in the opening and closing mechanism. In addition, since the rotating ring is in a state covered by the mounting plate, there is also room for improvement in maintainability.

[0006] The present invention is an invention focusing on the above-mentioned problems, and the technical problem to be solved is to provide a double-bearing reel which can realize the miniaturization of the side cover plate and improve the gripping property and has an opening and closing mechanism with good maintainability.

[0007] In order to achieve the above-mentioned purpose, the dual-bearing reel involved in the present invention has a reel body, and an opening and closing mechanism is arranged on the reel body, which can open and close the side cover relative to the frame, and the opening and closing mechanism has: an operating part, which is displaceably supported on the frame and exposed from the reel body; a moving part, which has a locking part; and a locking part, which is arranged on the side cover, and can be engaged and disengaged with the locking part when the moving part is displaced due to the operation of the operating part.

[0008] According to the double-bearing reel of the above structure, there is an opening and closing mechanism for opening and closing the side cover relative to the frame. Since a moving part having an operating part and a locking part is provided on the frame side, and a locking part that is engaged with the locking part is provided on the side cover side, the space for installing the moving part in the side cover can be omitted. As a result, the side cover can be made thinner, which can achieve miniaturization and improved grip. In addition, since the moving part is exposed when the side cover is removed from the frame by the opening and closing mechanism, it is possible to improve the maintainability.

[0009] According to the present invention, a double-bearing reel can be obtained which can realize a compact side cover plate and an improved gripping property and has an opening and closing mechanism with good maintainability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] First, refer to Figures 1 to 3 An overall structure of an embodiment of a dual-bearing reel 1 according to the present invention will be described. The reel body 1A of the dual-bearing reel 1 according to the present embodiment includes a cover body, i.e., a left cover plate 5A and a right cover plate 5B, which are installed to cover the side portions (left side portion 3A and right side portion 3B) of the frame 3 integrally formed into a predetermined shape. The left cover plate 5A and the right cover plate 5B of the present embodiment are formed into a substantially elliptical shape in a side view, and a reel 6 for winding a fishing line S is rotatably supported between the left and right cover plates.

[0012] A handle 7 for rotationally driving the reel 6 is provided on one of the two side covers provided on the left and right sides of the frame 3 (the left cover 5A side in this embodiment), and the rotational driving force of the handle 7 is transmitted to the reel 6 through a known power transmission mechanism provided in the internal space between the left cover 5A and the side portion 3A on the left side of the frame 3. In addition, the handle 7 may also be provided on the right cover 5B side.

[0013] In addition, a known uniform winding mechanism 9 having a fishing line guide 9a for guiding the fishing line is provided in front of the spool 6 between the left and right side covers, and the fishing line guide 9a is driven back and forth left and right in front of the spool 6 by a power transmission mechanism. Therefore, when the handle 7 is operated to reel in, the fishing line is uniformly wound on the spool 6 by the fishing line guide 9a that reciprocates left and right.

[0014] The frame 3 is formed integrally with the left side portion 3A and the right side portion 3B. The left side portion 3A is covered with a left cover plate 5A, and the right side portion 3B is installed with a right cover plate 5B. In addition, a connecting portion for connecting the left side portion 3A and the right side portion 3B is formed on the frame 3. The connecting portion may be formed at a plurality of locations, for example, at the front side, rear side, upper side, and lower side of the reel 6. In addition, these connecting portions may be covered with appearance parts such as metal as needed.

[0015] In the connection part, a reel foot 3C (reel foot 3C may be formed integrally with the frame 3) to be mounted on the reel seat of the fishing rod is formed integrally on the lower connection part provided below the spool 6. In addition, the connection part 3D on the upper side of the spool 6 may also function as a thumb rest on which fingers can be placed when holding the reel body 1A.

[0016] The shapes of the left side portion 3A, the right side portion 3B of the frame 3 and the left side cover 5A, the right side cover 5B covering them are not particularly limited. In the present embodiment, the outer peripheral shape is configured to be a non-circular (roughly elliptical) shape extending in the front-rear direction in a side view (see Figure 3 At this time, since the driving gear is installed on the side where the handle 7 is provided (the left side portion 3A of the frame 3 and the left side cover plate 5A), in order to ensure its storage portion, it can also be a shape different from the right side portion 3B of the frame 3 and the right side cover plate 5B.

[0017] In addition, a circular opening (circular opening) is formed on one of the left side 3A and the right side 3B of the frame 3 in order to insert and remove the reel 6 along the axial direction. In this embodiment, since the right side cover 5B is a structure that can be removed from the frame 3 by the following opening and closing mechanism, the circular opening is formed on the right side 3B of the frame 3.

[0018] The opening and closing mechanism is a mechanism that can open and close (install and remove) the side cover relative to the frame 3 in order to be able to install and remove the reel 6 or perform maintenance on various functional parts. In the present embodiment, it is constructed so that the right side cover 5B, which is opposite to the handle, can be opened and closed (install and remove) from the right side 3B of the frame 3.

[0019] Below, refer to Figures 4 to 6 The opening and closing mechanism 20 of this embodiment will be described. The opening and closing mechanism 20 includes: an operating portion 21a supported displaceably on the frame 3 (right side portion 3B) and exposed from the reel body 1A; and a moving member 21 having a locking portion 21b. The moving member 21 only needs to be movably held on the frame 3, and is moved by operating the operating portion 21a. In addition, the opening and closing mechanism 20 is provided on the right side cover 5B, and has a locking portion 23 that can be engaged with and disengaged from the locking portion 21b when the moving member 21 is displaced by the operation of the operating portion 21a.

[0020] That is, when the operating portion 21a is operated to move the movable member 21 and the locking portion 21b is engaged with the engaging portion 23, it becomes a locked state. When the operating portion 21a is operated to move the movable member 21 and the engagement between the locking portion 21b and the engaging portion 23 is released, it becomes an unlocked state.

[0021] The moving member 21 is held so as to be movable along the surface of the right side portion 3B of the frame 3. At this time, in order to realize the efficiency of the moving space and to make the locking portion 21b and the engaging portion 23 engage and disengage in a stable state, the moving member 21 preferably has an arc-shaped portion. In addition, in order to prevent the locking portion 21b and the engaging portion 23 from having a larger diameter or having a thicker wall in the axial direction, the locking portion 21b is preferably provided on the inner side (radially inner side) of the arc-shaped portion.

[0022] The moving member 21 of this embodiment is formed on the right side 3B of the frame 3 and is formed in a ring shape arranged around a circular opening 3E through which the reel 6 passes (hereinafter, the moving member 21 formed in a ring shape is also referred to as the "opening and closing rod 21"). The opening 3E is formed to have a diameter substantially the same as that of the flange of the reel 6. Figure 4 In the embodiment, the opening edge of the circular opening 3E is in a state of overlapping with the inner edge 21A of the opening and closing lever 21 .

[0023] The opening and closing lever 21 is integrally formed with a locking portion 21b on the radial inner side (inner edge 21A) so as to protrude toward the center. The number of locking portions 21b is not limited, but Figure 4 In the illustrated configuration, three locations are formed at approximately 120° intervals. Furthermore, an operating portion 21 a is integrally formed on the radially outer side of the opening and closing lever 21 so as to protrude radially outward.

[0024] The operating portion 21a is configured to protrude from the reel body 1A and can be slidably operated by fingers. Therefore, a cutout portion 24 is formed at a position where the right side portion 3B of the frame 3 faces the right side cover 5B, and the operating portion 21a is configured to protrude to the outside from the cutout portion 24. At this time, it is preferred that the cutout portion 24 is formed on the outer surface of the right side portion 3B of the frame, and is formed in advance at a position that is not touched by fingers when the reel is normally used, such as the lower end of the reel body 1A.

[0025] The mounting plate 30 is mounted on the inner side of the right cover plate 5B. The mounting plate 30 of this embodiment is formed into a substantially cylindrical shape and is fixed to the inner surface of the right cover plate 5B by screws 32 (or multiple screws). In addition, the outer peripheral surface 30a of the mounting plate 30 and the outer peripheral surface of the flange of the reel 6 are substantially flush with each other and are inserted into the circular opening 3E of the frame 3.

[0026] An annular protrusion 30b for bearing support is formed in the central area of ​​the mounting plate 30. A bearing 60 (see FIG. 1 ) for supporting the end of the drive shaft of the reel 6 is arranged in the inner space of the protrusion 30b. Figure 6 (a)(b)), and is prevented from coming off in the axial direction by a prevention member (not shown).

[0027] In addition, a known recoil prevention device (magnetic brake device) is held on the outer peripheral side of the protrusion 30b. The recoil prevention device includes an inner ring magnet 50 and an outer ring magnet 51 arranged concentrically, the inner ring magnet 50 is fixed to the outer peripheral wall of the protrusion 30b, and the outer ring magnet 51 is rotatably supported on the mounting plate 30.

[0028] The outer ring magnet 51 is supported on a support portion 53, which is rotatably supported on the mounting plate 30, and a tooth portion (not shown) formed on the support portion 53 meshes with a tooth portion 55a of an adjustment dial 55 rotatably supported on the mounting plate 30. The adjustment dial 55 is partially exposed from the lower side of the right cover plate 5B, and by rotating the adjustment dial 55, the outer ring magnet 51 can be rotated by the meshing relationship between the teeth.

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

[0030] As described above, the mounting plate 30 is formed in a substantially cylindrical shape, and the three engaging portions 23 that respectively engage with and disengage from the three locking portions 21 b of the opening and closing lever 21 are formed on the outer peripheral surface 30 a thereof. Here, the locking portion 21b and the engaging portion 23, which are components of the opening and closing mechanism 20 in this embodiment, will be described. Figure 6 In addition to Figure 5 In addition to the right cover plate 5B shown, the positional relationship of the opening and closing lever 21 disposed along the periphery of the opening 3E of the frame 3 (right side portion 3B) is shown for easier understanding.

[0031] In the aligned state, the right side cover plate 5B covers the frame 3 (right side portion 3B) in the axial direction. Therefore, the position of the locking portion 21b formed on the opening and closing lever 21 is aligned with the three engaging portions 23 formed on the outer peripheral surface 30a of the mounting plate 30. That is, the engaging portions 23 are respectively formed on the outer peripheral surface 30a of the mounting plate 30 corresponding to the positions where the locking portions 21b enter.

[0032] The engaging portion 23 of this embodiment includes: a cutout portion 30d formed on the outer peripheral surface 30a of the mounting plate 30 at approximately 120° intervals; and an annular groove 30e formed on the axially outer side of the cutout portion 30d and having a groove width that enables the locking portion 21b to move in the circumferential direction.

[0033] The operation of the opening and closing mechanism 20 configured as described above will be described. Figure 6 (a) shows the inner side of the right side cover 5B in a state (locked state) where the right side cover 5B is mounted on the right side portion 3B of the frame 3. At this time, each locking portion 21b of the opening and closing lever 21 is embedded in the annular groove 30e of the mounting plate 30, and each locking portion 21b is restricted by the wall portion 30f of the annular groove 30e, and is in a state (locked state) fixed to the right side portion 3B of the frame 3. In this way, by fitting the locking portions 21 b into the annular groove 30 e , the right side cover 5B can be securely locked, thereby preventing it from falling off.

[0034] When from Figure 6(a), when the operating portion 21a is pinched and moved to the rear side of the reel body, Figure 6 As shown in (b), the locking portions 21b of the opening and closing lever 21 are located in the cutout portions 30d of the mounting plate 30. At this time, the right side cover 5B is in a state (unlocked state) in which it can be removed from the right side portion 3B of the frame 3. Thus, the right side cover 5B can be grasped and moved in the axial direction, and the right side cover 5B can be removed from the frame 3, and the reel 6 can be removed from the opening 3E of the frame 3.

[0035] It is preferable to provide the frame 3 with positioning parts 3g and 3h (see Figure 4 ). Thus, the opening and closing lever 21 can be stopped from rotating at the position of the unlocked state in which the engagement is released and the position of the locked state in which the engagement is engaged.

[0036] When the right side cover 5B is mounted on the frame 3, the right side cover 5B is in the position where the operating portion 21a of the opening and closing lever 21 is located. Figure 6 (b) is aligned with and integrated with the right side portion 3B of the frame 3. Then, in this state, by operating the operating portion 21a to Figure 6 The position shown in (a) can be locked.

[0037] According to the above configuration, the opening and closing rod 21 of the opening and closing mechanism 20 is provided on the right side 3B of the frame 3, so that the space for installing the opening and closing rod in the right side cover 5B can be omitted. Thus, the right side cover 5B can be thinned, and miniaturization and improved grip can be achieved.

[0038] At this moment, Figure 5 As shown in (b), since the right cover plate 5B can make the inclined state 5B2 from the center C to the bottom in the vertical direction larger than the inclined state 5B1 from the center to the top, the reel body 1A can be narrowed (sharpened), thereby improving the grip. In addition, by forming the engaging portion 23 on the outer peripheral surface 30a of the mounting plate 30 and arranging the locking portion 21b on the radial inner side of the ring-shaped opening and closing rod 21, space efficiency can be achieved and the reel body can be miniaturized.

[0039] In addition, since the opening and closing rod 21 of the opening and closing mechanism 20 is formed in a ring shape around the opening of the insertion and extraction reel 6, and the operating part 21a is rotated, space efficiency can be achieved. At the same time, since it can be operated along an arc-shaped trajectory, the rotation action can be stabilized.

[0040] Furthermore, when the right cover 5B is removed from the right side portion 3B of the frame 3 by the opening and closing lever 21, the opening and closing lever 21 is exposed, thereby improving the maintainability.

[0041] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible. Although the above-mentioned opening and closing mechanism 20 is a structure in which the engaging portion 23 is provided on the outer peripheral surface of the mounting plate 30 of the right side cover 5B, the engaging portion may be provided on the right side cover 5B without providing the mounting plate. In addition, as for the shape of the moving member (opening and closing lever 21), it is sufficient as long as it is a structure that is movably held on the frame side, and the structure of the locking portion 21b or the structure of the engaging portion 23 may be appropriately modified accordingly.

[0042] In addition, although three engaging portions and locking portions are provided in the above-mentioned embodiment, the number of the engaging portions and the locking / releasing structure are not limited, and can be appropriately modified according to the shape and size of the reel body. Furthermore, if it is a right-handle type double-bearing reel, it is only necessary to provide the same opening and closing mechanism 20 on the left cover plate 5A and the left side portion 3A.
