Description
[Technical Field]
[0001] The present invention relates to a braking force adjusting body for adjusting the drag force in a double-bearing reel. [Background technology]
[0002] Fishing reels, such as double-bearing reels and spinning reels, are equipped with a drag mechanism that brakes the rotation of the spool in the line-out direction. The drag force (the braking force of the reel) of the drag mechanism can be adjusted by operating a control component such as a knob or pin.
[0003] Double-bearing reels have the advantage of transmitting the rotational force of the handle to the line more easily and having greater winding force compared to spinning reels. In double-bearing reels, the spool is braked by operating a braking force adjustment mechanism such as a star drag that screws onto the handle shaft or a lever drag provided on the reel body. As a braking force adjustment mechanism for double-bearing reels, a star drag is commonly used because it is located near the handle and makes it easy to adjust the drag force. Here, the star drag is a braking force adjustment mechanism that has multiple radial protrusions formed at equal intervals in the circumferential direction.
[0004] Patent Document 1 describes a braking force adjustment body comprising a nut that screws onto a handle shaft, a collar having a skirt portion fitted to one side of the outer circumference of the nut to restrict axial movement, and a braking force adjustment knob.
[0005] Patent Document 2 describes a star drag having a nut member that screws onto a first male threaded portion of a drive shaft, and a main body member that supports the nut member so that it can rotate integrally and move in the axial direction. [Prior art documents] [Patent Documents]
[0006] [Patent Document 1] Japanese Patent Publication No. 2010-35438 [Patent Document 2] Japanese Patent Publication No. 2018-203 [Overview of the project] [Problems that the invention aims to solve]
[0007] For anglers, one of the pleasures is not only catching fish, but also improving the functionality of fishing gear such as reels, or customizing them to their liking by replacing parts (for example, modifying a reel by replacing parts is called reel customization).
[0008] Various parts are available for customizing double-bearing reels, including handle arms, handle knobs, star drags, and mechanical brake knobs. In particular, the star drag is a crucial component for improving both appearance and performance, and various types are sold by different manufacturers.
[0009] In reel customization, the shape and positional relationship of each part differ depending on the manufacturer and model, so it is important that they do not interfere with other parts and can be installed without any unnecessary gaps (compatibility). In particular, for braking force adjusters such as the star drag, which are located between the handle and the reel case and are close to mechanical brake knobs, the shape and size are easily restricted, making it difficult to obtain parts that satisfy both appearance and compatibility.
[0010] In the braking force adjustment body described in Patent Document 1, the braking force adjustment knob is fitted to the other side of the nut and integrated with the nut and collar by crimping or other crushing process on the end of the nut. Furthermore, in the star drag described in Patent Document 2, the main body member is formed as a single member having an operating part for operating the rotation of the drag and a nut housing part for housing the nut.
[0011] Conventional braking force adjusters for double-bearing reels, whether genuine parts from reel manufacturers or custom parts, are provided as a single integrated component as described above. As a result, it was sometimes difficult to obtain a braking force adjuster of the desired shape to suit various handle and reel shapes.
[0012] The present invention has been made in view of such circumstances, and an object thereof is to provide a braking force adjusting body having excellent freedom in reel customization.
Means for Solving the Problems
[0013] The braking force adjusting body of the present invention adjusts the braking force of a reel in a drag mechanism of a two-bearing reel, and has a substantially annular main body portion and a plurality of protruding portions extending radially from the main body portion. An operation member provided with an opening around the rotation axis of the main body portion, an insertion portion inserted into the opening, and a nut housing portion housing a nut screwed to the handle shaft of the drag mechanism therein, and the handle shaft and the operation member are connected via the nut. A connecting member, and a fixing member detachably attached to the connecting member and sandwiching and fixing the operation member between the connecting member and the fixing member.
[0014] The connecting member has a detent portion that prevents the operation member from rotating independently in the circumferential direction with respect to the connecting member, and the detent portion is characterized by fitting complementarily with the operation member.
[0015] The fixing member has a screw portion, the insertion portion has a screw portion that can be screwed with the screw portion of the fixing member, and the operation member is pressed from the fixing member to the connecting member by fastening the fixing member and the insertion portion.
[0016] The fixing member has a female screw on its inner peripheral surface, and the insertion portion has a male screw on its outer peripheral surface. [[ID=The braking force adjusting body of the present invention has a substantially annular main body portion and a plurality of protruding portions extending radially from the main body portion, an operating member provided with an opening around the rotation axis of the main body portion, an insertion portion inserted into the opening, and a nut housing portion that houses a nut that engages with the handle shaft of the drag mechanism inside. It includes a connecting member that connects the handle shaft and the operating member via the nut, and a fixing member that is detachably attached to the connecting member and sandwiches and fixes the operating member between itself and the connecting member. Therefore, by combining each member, a braking force adjusting body with a desired shape and size can be easily obtained, and it has excellent freedom in reel customization.
[0019] The connecting member has a detent portion that prevents the operating member from rotating independently in the circumferential direction with respect to the connecting member. The detent portion fits complementarily with the operating member, so the force for rotating the operating member is transmitted to the nut housed in the connecting member without waste, and it has excellent operability.
[0020] The fixing member has a threaded portion, the insertion portion has a threaded portion that can be screwed with the threaded portion of the fixing member, and the operating member is pressed from the fixing member to the connecting member by fastening the fixing member and the insertion portion. Therefore, the operating member is firmly fixed to the connecting member, and the force for rotating the operating member is easily transmitted to the nut housed in the connecting member.
[0021] The fixing member has an internal thread on its inner peripheral surface, and the insertion portion has an external thread on its outer peripheral surface. Therefore, it has a simple structure and can firmly fix the operating member to the connecting member.
[0022] The fixing member has a plurality of recesses provided along the circumferential direction, so it is easy to fix and remove the operating member, and it has even better freedom in reel customization.

[Figure 4] These are side views of each component. [Figure 5] This is a perspective view of each component as seen from the handle side. [Figure 6] This is a perspective view of each component as seen from the reel body side. [Figure 7] This is a perspective view of another example of a connecting member. [Modes for carrying out the invention]
[0024] An example of the braking force adjuster of the present invention will be described with reference to Figures 1 to 3. Figure 1 is a side view of a double-bearing reel equipped with the braking force adjuster of the present invention. As shown in Figure 1, the braking force adjuster 1 of the present invention is inserted through the handle shaft Sh, which has a threaded portion formed on it, in the drag mechanism 110 of the double-bearing reel 100, and is provided between the handle 120 and the reel body 130. A nut that screws onto the handle shaft Sh extending from the reel body is housed inside the braking force adjuster 1 so as to fit together, and by rotating the braking force adjuster 1, the frictional force between the drag washers inside the drag mechanism 110 can be changed to adjust the braking force of the reel. The braking force adjuster 1 is provided with an appropriate shape and size so as not to interfere with the handle 120, the reel body 130, and the mechanical brake knob 140.
[0025] Figure 2 is a perspective view of the braking force adjuster of the present invention. As shown in Figure 2, the braking force adjuster 1 of the present invention comprises an operating member 2, a connecting member 3, and a fixing member 4. When the braking force adjuster 1 is attached to a reel, the upper side of the paper is the handle side, and the lower side of the paper is the reel body (spool) side. In the braking force adjuster 1, the fixing member 4 is provided on the handle side with respect to the operating member 2, and the connecting member 3 is provided on the reel body side.
[0026] In Figure 2, the operating member 2 has a roughly annular main body 21 and five projections 22 extending radially from the main body 21. The five projections 22 are formed radially, spaced equally in the circumferential direction. Note that there are not limited to five projections 22; there can be any number, for example, three to eight. The connecting member 3 has a nut housing 31 that houses a nut (not shown) inside. As described above, the nut is screwed onto the handle shaft, which is part of the drag mechanism, and the connecting member 3 connects the handle shaft and the operating member 2 via the nut. The fixing member 4 is annular and fixes the operating member 2 between itself and the connecting member 3. The fixing member 4 can be detachably attached to the connecting member 3. Note that the fixing member 4 is not limited to annular shape; it may also be polygonal or roughly polygonal.
[0027] An opening 24 (see Figure 5) is provided around the rotation axis O of the operating member 2. The operating member 2 is fixed to the connecting member 3 by the opening 24 being sandwiched between the connecting member 3 and the fixing member 4, and the three members become one unit. As a result, when the projection 22 of the braking force adjuster 1 is pressed and the operating member 2 is rotated in the circumferential direction, the connecting member 3 and the fixing member 4 also rotate together as a unit.
[0028] Because the braking force adjusting body of the present invention has the above configuration, the combination of the operating member, connecting member, and fixing member can be freely changed, making it easy to obtain a braking force adjusting body with an appropriate combination of members depending on the reel structure and the shape of other members.
[0029] Figure 3 is a side view of the braking force adjuster of the present invention. As shown in Figure 3, the connecting member 3 has an insertion portion 32 that extends toward the operating member 2 in the direction of the rotation axis O and is inserted into the opening of the operating member 2. The connecting member 3 also has a skirt portion 33 that extends in the direction opposite to the extension direction of the insertion portion 32. The nut housing portion only needs to be provided inside the connecting member 3, and can be provided inside the insertion portion 32, inside the skirt portion 33, or inside both the insertion portion 32 and the skirt portion 33.
[0030] In Figure 3, the end of the insertion portion 32 protrudes toward the handle side of the operating member 2. This allows the end of the insertion portion 32 to act as a spacer, adjusting the distance between the operating member 2 and the handle. Note that the end of the insertion portion 32 does not necessarily have to protrude toward the handle side of the operating member 2. The projection 22 extends while gently curving toward the reel body side (downward side of the paper). By using a connecting member 3 with a spacer function and an operating member 2 with a projection 22 that curves toward the reel body side, interference between the braking force adjuster 1 and the handle, reel body, etc. is less likely to occur. Note that the projection 22 may extend straight radially from the main body portion 21, or it may extend while gently curving toward the handle side (upward side of the paper). Also, the projection 22 may curve circumferentially while extending radially. In that case, there may be more than one curved portion. Furthermore, it is preferable that each projection 22 has the same shape and curves in the same direction. Furthermore, the projection 22 may be thicker at its ends than in its middle section.
[0031] Each component constituting the braking force adjuster of the present invention will be described with reference to Figures 4 to 6. Figure 4 is a side view of each component. Figure 4(a) shows the fixing member, Figure 4(b) shows the operating member, and Figure 4(c) shows the connecting member.
[0032] In Figure 4, the length L of the insertion portion 32 in the direction of the rotation axis O. i The width W of the main body 21 of the operating member 2 is shown. b The length of the insertion portion 32 is greater than (length in the direction of the rotation axis O in a side view), and when used as a braking force adjuster, the end of the insertion portion 32 protrudes towards the handle side of the operating member 2. Note that the length L of the insertion portion 32 i The width of the main body 21 is W b Same as, or width W b It may be even smaller. As a result, the end of the insertion portion 32 does not protrude toward the handle side beyond the operating member 2, making it easier to attach the handle even if the handle shaft is short.
[0033] Thickness T of fixing member 4 f For example, the width W of the main body 21. bWhen it is smaller, if it is made into a braking force adjusting body, the fixing member 4 is easily accommodated in the fixing member accommodating portion inside the main body portion 21 and becomes difficult to be visually recognized in side view (see FIG. 3). Thereby, the fixing member 4 is less likely to interfere with the handle, and the compatibility of the braking force adjusting body with the reel can be adjusted by the selection of the operation member 2 and the connecting member 3. Note that the thickness T of the fixing member 4 f may be the same as the width W of the main body portion 21 b or may be larger than the width W b
[0034] FIG. 5 is a perspective view of each member as viewed from the handle side. FIG. 5(a) shows the fixing member, FIG. 5(b) shows the operation member, and FIG. 5(c) shows the connecting member. As shown in FIG. 5, a through hole 23 along the direction of the rotation axis O is provided in the main body portion 21 of the operation member 2. The main body portion 21 has an opening 24 with a substantially hexagonal inner peripheral shape around the rotation axis O on the side of the connecting member 3 of the through hole 23. Further, the main body portion 21 has a fixing member accommodating portion 25 for accommodating the fixing member 4 on the side of the fixing member 4 of the through hole 23
[0035] The insertion portion 32 has a rotation preventing portion 321 with an outer peripheral shape that is substantially hexagonal and contacts the inner peripheral surface of the opening 24 over the entire circumference, and is adjacent to the skirt portion 33. Thereby, even if the operation member 2 is not strongly pressed against the connecting member 3 by the fixing member 4, the rotational force can be transmitted from the operation member 2 to the connecting member 3 and the nut (not shown). Note that the inner peripheral shape of the opening 24 and the outer peripheral shape of the rotation preventing portion 321 are not limited to being substantially hexagonal as long as the rotational force of the operation member 2 is transmitted to the nut, and may be non-circular shapes such as substantially pentagonal, substantially heptagonal, elliptical, wavy, or gear-shaped. The inner peripheral shape of the opening 24 and the outer peripheral shape of the rotation preventing portion 321 may be a substantially polygon with the corners of the vertices being curved surfaces or a polygon without being curved. Further, the rotation preventing portion 321 may be in contact with a part of the inner peripheral surface of the opening 24
[0036] The thickness T of the opening 24 in the direction of the rotation axis O a is, for example, the same as the thickness T of the rotation preventing portion 321 s or may be made the same as the thickness T s It can be made larger than that. Thickness T of opening 24 a However, the thickness T of the anti-rotation part 321 s If the thickness T is greater than the operating member 2, the operating member 2 is more easily pressed toward the connecting member 3, and as a result of the increased rotational frictional force between the operating member 2 and the connecting member 3, combined with the fitting effect described above, the transmission of rotational force is improved. a From the viewpoint of ensuring that the opening 24 and the anti-rotation part 321 are sufficiently fitted together to transmit rotational force, the width W of the main body part 21 is considered. b The thickness is preferably about 0.5 to 0.9 times (see Figure 4).
[0037] The connecting member 3 is not limited to the above form, as long as it has a rotation-preventing portion 321 that prevents the operating member 2 from rotating independently in the circumferential direction relative to the connecting member 3. The rotation-preventing portion 321 preferably fits complementaryly with the operating member 2, thereby making it easier for the operating member 2 and the connecting member 3 to move as a single unit. The connecting member 3 may, for example, have a rotation-preventing portion on the skirt portion 33. In that case, it is preferable that the connecting member 3 has a protruding rotation-preventing portion 321 on the flange portion 34 on the operating member 2 side of the skirt portion 33, and the operating member 2 has a recessed fitting portion that fits complementaryly with this rotation-preventing portion 321. The protruding rotation-preventing portion 321 protrudes toward the operating member 2 side and fits with the fitting portion to prevent the connecting member 3 from rotating freely when the operating member is rotated. There may be one or more protruding rotation-preventing portions 321. Note that the connecting member 3 does not have to have a rotation-preventing portion 321.
[0038] The fixing member 4 has a threaded portion Sa on its inner circumferential surface. The insertion portion 32 also has a threaded portion Sb on its outer circumferential surface that can be screwed into the threaded portion Sa. In Figure 5, the threaded portion Sa is a female thread, and the threaded portion Sb is a male thread. As a result, the connecting member 3 and the fixing member 4 have a simple structure, and the rotation of the fixing member 4 allows for easy integration and removal of each member. The operating member 2 is pressed from the fixing member 4 to the connecting member 3 by fastening the fixing member 4 and the insertion portion 32, and is firmly integrated with the other members.
[0039] In addition to the method described above, the fixing member can also be attached to the connecting member by providing screw holes as threaded portions at corresponding positions on both the fixing member and the connecting member, inserting screws from the fixing member to the connecting member, and fastening the two members together. Furthermore, the fixing member can be attached to the connecting member using any method that allows for detachable attachment, such as press-fitting or magnetic joining. From the viewpoint of ease of transmission of rotational force and integration of each member, it is particularly preferable that the connecting member has an anti-rotation portion and that the fixing member is attached to the connecting member by screwing the threaded portions together.
[0040] In Figure 5, the fixing member 4 has four recesses 41 provided along the circumferential direction. This makes it easy to fix and remove the operating member 2 by engaging a jig or the like in the recesses 41, resulting in excellent workability for reel customization. When the fixing member 4 has a threaded portion Sa and is attached to the insertion portion 32 by screwing it in, the fixing member 4 is easy to rotate, resulting in particularly excellent workability. Note that the fixing member 4 does not necessarily have recesses 41. From the viewpoint of firmly fixing the operating member 2, it is preferable that the fixing member 4 has multiple recesses 41. The recesses 41 may be holes that penetrate in the direction of the rotation axis O, or they may be non-penetrating depressions. From the viewpoint of ease of engagement with a jig and ease of confirming the fixed state, it is preferable that the recesses 41 are holes that penetrate in the direction of the rotation axis.
[0041] Figure 6 is a perspective view of each component as seen from the reel body side. Figure 6(a) shows the fixing member, Figure 6(b) shows the operating member, and Figure 6(c) shows the connecting member. As shown in Figure 6, the thickness T of the operating member 2. c The width of the main body 21 is W b It is thinner than the operating member 2, and a thin-walled portion 26 is formed on the side of the connecting member 3 of the operating member 2. Note that the operating member 2 does not necessarily have a thin-walled portion 26. When a relatively expensive material such as titanium is used as the material for the operating member 2, it is preferable that the operating member 2 has a thin-walled portion 26 from the viewpoint of cost reduction. When a thin-walled portion 26 is formed, the thickness T c From the standpoint of ensuring mechanical strength, the width W bIt is preferable that the thickness be about 0.05 to 0.5 times that of the operating member 2. Ribs may be formed on the side of the connecting member 3 of the operating member 2.
[0042] Furthermore, a cover may be provided on the side of the connecting member 3 of the operating member 2 so as to cover the thin-walled portion 26. This prevents inconvenience (pain from contact with the end face of the operating member 2 or line breakage) when the drag operation (operation in the opposite direction to normal) is performed with one hand while the rod and reel are held in one hand and the handle is held in the other hand. When a cover is provided on the operating member 2, the thin-walled portion 26 becomes the internal space of the operating member 2. In the case of a joint between the operating member 2 and the cover, such as by welding, if the outer circumference of the projection 22 is closed and there is a gap in the inner circumference on the connecting member 3 side, it is preferable to provide a sealing member (such as an O-ring) on the outer circumference of the connecting member 3 to fill the gap in order to prevent water from entering the internal space.
[0043] The nut housing portion 31 of the connecting member 3 has, for example, a quadrilateral inner shape, and fits into contact with the outer surface of the nut around its entire circumference, allowing the braking force adjuster and the nut to rotate together. The inner shape of the nut housing portion 31 can be any shape that allows the braking force adjuster and the nut to rotate together, and can be a non-circular shape such as a polygon other than a quadrilateral, a roughly polygonal shape, an ellipse, a wave shape, or a gear shape. The nut housing portion 31 may also fit into contact with a part of the outer surface of the nut.
[0044] Another example of the connecting member will be explained with reference to Figure 7. Figure 7(a) is a perspective view of the other example of the connecting member as seen from the handle side, and Figure 7(b) is a perspective view of the other example of the connecting member as seen from the reel body side. As shown in Figure 7(a), a top plate portion 35 is provided at the end of the insertion portion 32, and its opening is smaller than that of the end of the connecting member 3 shown in Figure 5. Also, as shown in Figure 7(b), a sound-emitting groove 36 is provided in the skirt portion 33 on the reel body side of the nut housing portion 31. This allows for reel customization even for drags with a mechanism that emits sound from the braking force adjustment body. Note that the sound-emitting groove 36 is not limited to the skirt portion 33, but may also be provided on the reel body side of the top plate portion 35.
[0045] The materials used for each component constituting the braking force adjuster of the present invention include, for example, metal materials and resin materials. Suitable metal materials include aluminum, magnesium, titanium, and stainless steel. Suitable resin materials include thermosetting resins such as epoxy resin and phenolic resin, various engineering plastics, and fiber-reinforced resin materials. Titanium, which has excellent mechanical strength, is particularly preferred as the material for the operating member. If the operating member has a thin-walled portion and this portion is covered by a cover, it is preferable to use carbon fiber reinforced resin, elastomer, or aluminum as the material for the cover. Furthermore, aluminum, which is relatively lightweight and has excellent processability, is preferred as the material for the connecting member and fixing member.
[0046] Each component constituting the braking force adjuster of the present invention can be manufactured, individually or in combination, by various methods such as press working, cutting, 3D additive manufacturing, casting, resin molding, and injection molding. From the viewpoint of improving durability, a surface treatment process may be incorporated into the manufacturing process. When a metal material is used as the material, a heat treatment process may be incorporated from the viewpoint of improving mechanical strength. In particular, when titanium is used as the material for the operating member, it is preferable to form a titanium plate by press working and then perform heat treatment to increase its mechanical strength.
[0047] The braking force adjusting body of the present invention has been described above based on the figures and other information, but the configuration of the present invention is not limited thereto. [Industrial applicability]
[0048] The braking force adjuster of the present invention offers excellent flexibility in reel customization, making it widely compatible with various double-bearing reels and widely usable as a custom part for double-bearing reels. [Explanation of Symbols]
