Description

  The present invention relates to a fishing reel spool.

  Fishing reels are required to be lighter in order to improve operability, retention, and the like. For this reason, a fishing reel provided with a spool formed of resin instead of metal is used. However, the durability of the resin spool is lower than that of the metal spool. For this reason, the outer surface of the spool is easily damaged by frictional contact with the fishing line wound around the spool.

  Patent Document 1 discloses a spool in which a metal coating layer is formed on the outer surface of a resin spool base material. In this spool, by providing the coating layer, the durability of the spool is improved, and the design (appearance gloss) and surface smoothness are improved.

  Patent Document 2 discloses a spool including a resin spool body in which a thread winding portion is provided between a front flange and a rear flange. In this spool, a metal cover is fixed to the outer surface of the front flange of the spool body. The cover is fixed to the front flange of the spool body by curling. A ceramic coating layer is provided on the outer surface of the cover. As described above, the surface hardness of the front flange is improved.

  Patent Document 3 discloses a spool including a resin spool body in which a yarn winding portion is provided on the front side of a rear flange. In this spool, a metal layer is provided on the outer surface of the spool body. A front flange is attached to the front side of the spool body. The front flange is a separate member from the spool body and is formed of a hard material. The outer surface of the front flange is subjected to an ultra-hard coating process. As described above, the surface strength and durability of the spool are improved.

  In the spool of Patent Document 1, the outer diameter of the front flange is larger than the outer diameter of the yarn winding portion. For this reason, an object etc. are easy to hit a front side flange. Although a metal film layer is provided on the outer surface of the front flange, a treatment for improving the strength as compared with other portions such as a yarn winding portion is not performed. Therefore, since the frequency with which an object or the like hits is high, the front flange is easily recessed.

  In the spool of Patent Document 2, a gap, a step, and the like are formed between the cover at the rear end of the front flange and the spool body. The fishing line released from the thread winding portion is easily caught in the gap and step. When the fishing line is caught in the gap or step, the resistance when releasing the fishing line increases. Moreover, since the cover fixed to the front flange is made of metal, the mass of the spool increases. Further, the ceramic coating layer on the outer surface of the cover is extended by curling when the cover is fixed to the front flange. Thereby, the designability (appearance gloss) of a ceramic coating layer falls, or the friction coefficient of the outer surface of a ceramic coating layer increases.

  In the spool of Patent Document 3, the front flange is a separate member from the spool body and is formed of a hard material. For this reason, the mass of the front side flange increases. Moreover, parts, such as a nut, for attaching a front side flange to a spool main body are needed. For this reason, the mass of the spool increases.

  The present invention has been made paying attention to the above-mentioned problems, and its object is to provide a fishing reel capable of improving strength, durability, thread release and design without increasing mass. Is to provide a spool.

  In order to achieve the above object, a fishing reel spool according to an aspect of the present invention is provided between a front flange, a rear flange, the front flange, and the rear flange, and the fishing line is wound around the spool. A spool body made of resin and a metal layer portion formed on the outer surface of the spool body, the layer portion provided on the outer surface of the front flange And a second layer forming portion provided on an outer surface of the yarn winding portion and having a thickness smaller than that of the first layer forming portion.

In the fishing reel spool, the layer portion preferably includes a plated layer and a physical vapor deposition layer provided on the outer layer side of the plated layer and serving as the outermost layer of the first layer forming portion.
In addition, the plating layer is provided in the first plating layer forming part and the second layer forming part provided in the first layer forming part, and is thinner than the first plating layer forming part. It is preferable to include a second plating layer forming part.
Furthermore, the front side flange is provided on a rear end surface of the yarn winding part side, and includes a step part that forms an inner peripheral side higher than an outer peripheral side, and the physical vapor deposition layer includes the first layer forming part and the It is also preferable to provide an end portion that is provided between the second layer forming portion and abuts against the stepped portion from the outer peripheral side.

  In the above-described spool, since the thickness of the first layer forming portion provided on the outer surface of the front flange is larger than the thickness of the second layer forming portion provided on the outer surface of the yarn winding portion, The rigidity and strength of the layer forming part 1 are improved. Thereby, when an object etc. hit, it can be set as the structure which is hard to dent a front side flange. Further, even when the fishing line comes into frictional contact with the front flange, the front flange can be hardly damaged.

  In addition, since the above-described spool is not configured to attach another member such as a cover to the outer surface of the front flange, there is no step, gap, or the like between which the fishing line is easily caught. For this reason, it is difficult for the fishing line to be caught when the fishing line is released, and the line releasing property can be improved.

  In the above-described spool, the spool body is formed of a resin material. In addition, the metal layer portion is formed thick only in the first layer forming portion provided on the outer surface of the front flange where the load is easily applied. In other words, the second layer forming portion and the like provided on the outer surface of the yarn winding portion where the load is difficult to be applied and the fishing line is not easily brought into frictional contact are formed thin. As a result, a lightweight spool having an excellent balance of strength against load can be provided.

  Further, in the above-described spool, a physical vapor deposition layer is formed as the outermost layer of the first layer forming portion. For this reason, when the fishing line comes into frictional contact with the front flange when the fishing line is released, the frictional resistance between the fishing line and the physical vapor deposition layer is reduced. Thereby, thread | yarn discharge | release property can be improved more.

  Further, in the above-described spool plating layer, the thickness of the second plating layer forming portion is made thinner than the thickness of the first plating layer forming portion. Thereby, the thickness of the second layer forming portion is thinner than the thickness of the first layer forming portion. The plating layer has higher strength and elastic modulus than the physical vapor deposition layer, and the cost of forming it is low. Moreover, the plating layer can be easily composed of a plurality of layers, and the thickness can be easily adjusted. Therefore, by providing the plating layer with the first plating layer forming part and the second plating layer forming part and adjusting the thickness of the plating layer, the first layer forming part and the second layer forming part It is possible to easily adjust the thickness of the layer portion.

  Further, in the above-described spool, a step portion whose inner peripheral side is higher than the outer peripheral side is formed on the rear end surface of the front flange on the yarn winding portion side. And the edge part of the physical vapor deposition layer is contacting the step part from the outer peripheral side. This makes it difficult for the fishing line to be caught on the end of the physical vapor deposition layer when the fishing line is released. Accordingly, the yarn releasing property can be further improved.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view showing a fishing spinning reel 1. As shown in FIG. 1, a fishing spinning reel 1 includes a reel body 2. The reel body 2 is provided with a leg portion 3 attached to a fishing rod (not shown). A handle 4 is rotatably attached to the reel body 2.

  A drive gear 5 that rotates by rotating the handle 4 is provided inside the reel body 2. A pinion gear 6 is meshed with the drive gear 5. A spool shaft 7 is inserted through the pinion gear 6 in the axial direction. A spool 8 around which a fishing line (not shown) is wound is rotatably attached to the spool shaft 7.

  A rotor 9 that can rotate integrally with the pinion gear 6 is attached to the pinion gear 6. The rotor 9 includes a pair of arm portions 10A and 10B provided in an opposed state. A swing arm 11A is attached to the arm portion 10A, and a swing arm 11B is attached to the arm portion 10B. One end of the bail 12 is connected to the swing arm 11A, and the other end of the bail 12 is connected to the swing arm 11B. Thereby, the bail 12 is supported so that rotation between a fishing-line discharge | release state and a fishing-line winding state is possible. Further, the swing arm 11A is provided with a line roller 13 which is a fishing line guide mechanism.

  The drive gear 5 is engaged with an oscillating mechanism 14. As the drive gear 5 rotates, the oscillating mechanism 14 moves the spool shaft 7 in the axial direction.

  When winding the fishing line, the rotor 9 is rotated via the drive gear 5 and the pinion gear 6 by rotating the handle 4. At the same time, the rotation operation of the handle 4 is transmitted to the spool shaft 7 via the drive gear 5 and the oscillating mechanism 14, and the spool shaft 7 moves in the axial direction. With the rotation of the rotor 9 and the movement of the spool shaft 7, the fishing line is wound evenly through the line roller 13 without being shifted to the spool 8.

  The spool 8 includes a spool body 15 and a spool cap 16 attached to the front side of the spool body 15. The spool cap 16 is provided with a drag knob 17. A drag mechanism (not shown) is provided inside the spool 8. By rotating the drag knob 17, the drag force when the fishing line is released is adjusted to a desired value via the drag mechanism. In this embodiment, the drag knob 17 is a front drag system provided at the front end of the spool 8, but the present invention is not limited to this. For example, a drag mechanism of a rear drag system or a rotor drag system may be provided.

  2 to 5 are views showing the spool body 15. The spool body 15 is formed of a resin material such as polyamide resin, glass fiber reinforced or carbon fiber reinforced polyamide resin, polycarbonate resin, ABS resin, or an alloy of polycarbonate resin and ABS resin. As shown in FIGS. 2 to 5, the spool body 15 includes a front flange 21 and a rear flange 22. Between the front side flange 21 and the rear side flange 22, a line winding portion 23 around which a fishing line is wound is provided. The outer diameter of the thread winding portion 23 is smaller than the outer diameter of the front flange 21 and the outer diameter of the rear flange 22. A skirt portion 24 is provided on the rear side of the rear flange 22.

  FIG. 6 is a diagram showing the configuration of the front flange 21, and FIG. 7 is a diagram showing the configuration of the yarn winding portion 23. 8A is an enlarged view of the range of X1 in FIG. 6, and FIG. 8B is an enlarged view of the range of Y1 in FIG. As shown in FIGS. 8A and 8B, a metal layer portion 25 is formed on the outer surface of the spool body 15. The layer portion 25 is provided on the outer surface of the first layer forming portion 26 provided on the outer surface of the front flange 21 and the yarn winding portion 23, and has a thickness T <b> 2 from the thickness T <b> 1 of the first layer forming portion 26. The second layer forming unit 27 is thin. The first layer forming portion 26 is provided in a range indicated by A in FIG. 6, and the second layer forming portion 27 is provided in a range indicated by B in FIG. 7. Between the first layer forming unit 26 and the second layer forming unit 27, the thickness decreases from the first layer forming unit 26 toward the second layer forming unit 27 (in FIG. 6). Range indicated by C).

  Here, the thickness T1 of the first layer forming part 26 is preferably 2 to 12 times the thickness T2 of the second layer forming part 27. In particular, the thickness T1 of the first layer forming portion 26 is preferably 80 μm to 400 μm, and more preferably 100 μm to 300 μm. Since the first layer forming portion 26 is located on the front flange 21 having a large outer diameter, when the thickness T1 is larger than 400 μm, not only the mass increases but also the inertia moment around the spool shaft 7 increases, Mechanism response decreases. Moreover, it is preferable that thickness T2 of the 2nd layer formation part 27 is 10 micrometers-40 micrometers.

  As shown in FIGS. 8A and 8B, the layer portion 25 includes a plating layer 30. As shown in FIG. 8A, the first layer forming unit 26 includes a physical vapor deposition layer 31 provided on the outer layer side of the plating layer 30. The plating layer 30 includes a nickel layer 32, a copper layer 33, a nickel layer 34, and a chromium layer 35. In the plating layer 30, the nickel layer 32, the copper layer 33, the nickel layer 34, and the chromium layer 35 are arranged in this order from the inner layer side. The nickel layer 32 is formed by an electroless plating process. The copper layer 33, the nickel layer 34, and the chromium layer 35 are formed by an electrolytic plating process.

  The plated layer 30 includes a first plated layer forming part 36 provided in the first layer forming part 26 and a second plated layer forming part 37 provided in the second layer forming part 27. In the second plating layer forming part 37, the copper layer 33 and the nickel layer 34 are thinner than the first plating layer forming part 36. That is, the thickness TM2 of the second plating layer forming portion 37 is thinner than the thickness TM1 of the first plating layer forming portion 36. For this reason, the thickness T2 of the second layer forming portion 27 is thinner than the thickness T1 of the first layer forming portion 26. The plating layer 30 may be composed of a single layer or a plurality of layers, but is preferably composed of a plurality of layers. When the plating layer 30 is composed of three or more layers, the thickness of the intermediate layer (in this embodiment, the copper layer 33 and the nickel layer 34) is changed to change the thickness of the first plating layer forming portion 36. It is preferable to make it thinner than the thickness TM1 of the second plating layer forming portion 37 than the thickness TM1. As a result, the dimensional stability and the stability of the surface shape of the spool 8 (for example, the accuracy of the groove shape, etc.) are improved, and the quality required for the spool 8 such as preventing fishing line misalignment and moisture release. Will improve.

  FIG. 9 is a diagram illustrating the electrolytic plating process. As shown in FIG. 9, a positive electrode 41A and a negative electrode 41B are used during the electrolytic plating process. The negative electrode 41B includes a jig 42. The jig 42 is in contact with a contact portion 43 provided inside the skirt portion 24 of the spool body 15. At this time, a plating layer (not shown) serving as a base is formed on the contact portion 43 of the spool body 15. The plus electrode 41 </ b> A is disposed in the vicinity of the front flange 21 of the spool body 15. Thereby, in the front side flange 21 in the vicinity of the plus electrode 41A, the thickness of the formed layer is increased. As described above, it is possible to increase the thickness of the copper layer 33 and the nickel layer 34 at the front flange 21 by electrolytic plating. In FIG. 9, the plus electrode 41 </ b> A is formed in a plate shape, but is preferably formed in a shape that covers the front flange 21. It is also preferable to provide a plurality of positive electrodes 41 </ b> A and arrange each positive electrode 41 </ b> A at an appropriate position near the front flange 21.

  The physical vapor deposition layer 31 is the outermost layer of the first layer forming unit 26. The physical vapor deposition layer 31 is formed by physical vapor deposition (PVD) such as ion plating or sputtering. The physical vapor deposition layer 31 is not provided in the second layer forming unit 27. That is, the physical vapor deposition layer 31 is provided in the range indicated by A in FIG. One end of the physical vapor deposition layer 31 is provided between the first layer forming unit 26 and the second layer forming unit 27. The physical vapor deposition layer 31 is formed to be thin, and the thickness is particularly preferably 0.1 μm to 5 μm. This makes it difficult for the fishing line to be caught on the end of the physical vapor deposition layer 31 between the first layer forming part 26 and the second layer forming part 27 when the fishing line is released. The physical vapor deposition layer 31 is preferably formed from TiN (titanium nitride). As a result, the spool body 15 has improved surface strength and a high-quality golden appearance. Moreover, the physical vapor deposition layer 31 may be formed from TiC, TiAlN, or TiCN. In particular, it is preferable that the physical vapor deposition layer 31 is formed of TiCN because the friction coefficient is small.

  Therefore, the spool 8 configured as described above has the following effects. In the spool 8, the outer diameter of the front flange 21 is larger than the outer diameter of the yarn winding portion 23. For this reason, an object etc. are easy to hit the front side flange 21. Therefore, in the spool 8, the thickness T1 of the first layer forming portion 26 provided on the outer surface of the front flange 21 is set to the thickness T2 of the second layer forming portion 27 provided on the outer surface of the yarn winding portion 23. It is thicker. For this reason, in the 1st layer formation part 26, rigidity and intensity | strength improve. In particular, in the first layer forming portion 26, the shear strength in the thickness direction against a load such as when a sharp object hits is improved. Thereby, when an object etc. hits, it will become the structure which the front side flange 21 cannot dent easily. In addition, even when the fishing line comes into frictional contact with the front flange 21, the front flange 21 is not easily damaged.

  In the spool 8, the physical vapor deposition layer 31 that is the outermost layer of the first layer forming portion 26 is formed thin. For this reason, it is difficult for the fishing line to be caught on the end of the physical vapor deposition layer 31 between the first layer forming part 26 and the second layer forming part 27 when the fishing line is released. Further, the configuration is not such that another member such as a cover is attached to the outer surface of the front flange 21. For this reason, the level | step difference, clearance gap, etc. which are easy to catch a fishing line are not formed between the front side flange 21 and the thread winding part 23. FIG. For this reason, at the time of releasing the fishing line, the fishing line is hardly caught and the line releasing property is improved.

  In the spool 8, the spool body 15 is formed of a resin material. Further, the metal layer portion 25 is formed thick only in the first layer forming portion 26 provided on the outer surface of the front flange 21 that is easily loaded. That is, the second layer forming portion 27 and the like provided on the outer surface of the yarn winding portion 23 that is difficult to apply a load and is difficult to frictionally contact the fishing line are formed thin. This provides a lightweight spool 8 with an excellent balance of strength with respect to the load.

  In the spool 8, a physical vapor deposition layer 31 is formed as the outermost layer of the first layer forming unit 26. For this reason, when the fishing line comes into frictional contact with the front flange 21 when the fishing line is released, the frictional resistance between the fishing line and the physical vapor deposition layer 31 is reduced. Thereby, thread | yarn discharge | release property improves. Moreover, by forming the physical vapor deposition layer 31 from TiN, it becomes a high-quality golden appearance, and the designability (appearance gloss) is improved. Furthermore, by forming the physical vapor deposition layer 31 from TiN, the wear resistance is improved, and the frictional resistance with the fishing line when the fishing line is released is further reduced.

  In the experimental results, the surface hardness of the range (first layer forming portion 26) indicated by A in FIG. 6 of the spool body 15 of the present embodiment is the case where the surface hardness is improved by the method shown in Patent Document 2 above. Compared to, it was improved by about 40%.

  Further, in the plated layer 30 of the spool 8, the thickness TM2 of the second plated layer forming portion 37 is made thinner than the thickness TM1 of the first plated layer forming portion 36. Thereby, the thickness T2 of the second layer forming portion 27 is thinner than the thickness T1 of the first layer forming portion 26. The plating layer 30 has higher strength and elastic modulus than the physical vapor deposition layer 31 and is low in cost to form. Moreover, the plating layer 30 can be easily composed of a plurality of layers, and the thickness can be easily adjusted. Therefore, by providing the plating layer 30 with the first plating layer forming portion 36 and the second plating layer forming portion 37 and adjusting the thickness of the plating layer 30, the first layer forming portion 26 and the second plating layer 30 are adjusted. It is easy to adjust the thickness of the layer portion 25 with the layer forming portion 27.

  The plated layer 30 includes a first plated layer forming part 36 provided in the first layer forming part 26 and a second plated layer forming part 37 provided in the second layer forming part 27. In the second plating layer forming part 37, the copper layer 33 and the nickel layer 34 are thinner than the first plating layer forming part 36. That is, the thickness TM2 of the second plating layer forming portion 37 is thinner than the thickness TM1 of the first plating layer forming portion 36. For this reason, the thickness T2 of the second layer forming portion 27 is thinner than the thickness T1 of the first layer forming portion 26.

  As described above, in the present embodiment, the physical vapor deposition layer 31 is not provided in the first layer forming unit 26. For this reason, compared with 1st Embodiment, the designability and thread | yarn discharge | release property fall. However, by increasing the thickness of the first metal layer forming portion 36, the thickness T1 of the first layer forming portion 26 is increased. For this reason, in the front side flange 21, the intensity | strength with respect to the load when a thing etc. hit and the intensity | strength when a fishing line carries out frictional contact are ensured.

(Third embodiment)

And the edge part 52 of the physical vapor deposition layer 31 has faced the step part 51 from the outer peripheral side. This makes it difficult for the fishing line to be caught by the end 52 of the physical vapor deposition layer 31 when the fishing line is released. Therefore, the yarn releasing property is further improved.
