Description

  The present invention relates to a fishing reel, and in particular, a dual bearing type in which a spool rotatably supported between side frames of a reel body can be wound and rotated by rotating a handle provided on one side of the reel body. The present invention relates to a fishing reel.

  In general, a double-bearing fishing reel includes a reel body formed by a frame (frame body) in which left and right side frames are connected with support columns and an outer plate attached to the side frame. A spool around which a fishing line is wound is rotatably supported between left and right cylindrical portions formed by the frame and the outer plate. Such fishing reels require a compact reel body in order to improve casting operation and fishing line winding operability, and increase the drive gear size to improve rotation transmission efficiency. Is requested. For this purpose, instead of forming the reel body's side that houses the take-up drive mechanism into a cylindrical structure, a part of the peripheral wall protrudes outward in the radial direction, and a large-diameter drive gear is formed on the protrusion. It is known to form in a deformed structure that accommodates.

  In this way, the reel body having a deformed structure by projecting a part of the cylindrical structure forms a discontinuous outer surface shape with respect to other parts, so that the peripheral wall part over the entire circumference has a uniform thickness. In addition, it is difficult to form the mating portion of the side frame and the outer plate on one surface formed with high accuracy. Further, when the thickness of the side frame and the outer plate includes a portion that is locally thinned or thickened, it is inconvenient for reducing the weight of the reel body and ensuring its strength.

For this reason, the mating part of the side frame and the outer plate in the part forming the protrusion is displaced along the axial direction of the spool with respect to the mating part in the other part, and the two mating parts are stepped. A double-bearing reel that is formed in a shape and fastened with screws at both of these mating portions has been proposed (see, for example, Patent Document 1).
JP2001-145442

  However, in order to fix the two members at the two mating portions, it is necessary to form two contact surfaces in a stepped shape per one member that abuts at the respective mating portions. It is extremely difficult to eliminate the dimensional variation between the contact surfaces of the two members and to make the two members contact each other with no gap between each pair of stepped contact surfaces facing each other.

  For this reason, when each of the two mating portions formed in a step shape is fixed with screws, the outer plate is inclined, bent, etc. due to the effect of the gap formed in one mating portion, and accommodated inside. The meshing performance and durability of the gear will be reduced.

  The present invention has been made based on such circumstances, and the reel body in which a portion for housing the drive gear of the take-up drive mechanism protrudes radially outward is robust without being affected by variation in dimensions. It is an object of the present invention to provide a fishing reel that forms a single integrated structure and can reliably prevent a reduction in meshing performance and durability of a gear housed therein.

  In order to achieve the above object, according to the present invention, a reel body is provided which has an outer plate attached to a side frame of a frame and which rotatably supports a spool for winding a fishing line. A gear box that houses a winding drive mechanism that winds and rotates the spool is formed between the plate and the outer peripheral portion of the drive gear of the winding drive mechanism. The peripheral wall of the gear box expands radially outward. A first mating portion that is accommodated in the protruding bulging portion and has a side frame facing the outer plate at the bulging side portion including the bulging portion, and a side at the anti-bulging side portion on the diametrically opposite side of the bulging portion A fishing reel in which a second mating portion whose frame faces the outer plate is arranged in a step shape along the axial direction of the spool, and one of the first mating portion and the second mating portion. A fishing reel is provided in which the side frame and outer plate are fastened and fixed together by a plurality of screws. It is.

  The side frame may be formed in a circular shape, and the opening portion of the bulging portion that opens on the side frame side may be closed with a closing plate fixed to the side frame.

  According to this fishing reel, the bulge portion that accommodates the outer peripheral portion of the drive gear is formed on the outer peripheral portion of the gear box of the winding drive mechanism formed by the side frame and the outer plate, so that it is compact but large. The reel main body can accommodate a drive gear of a diameter and is not affected by variation in dimensions by fastening and fixing the side frame and the outer plate integrally with a plurality of screws in one of the two mating portions. Is provided with a fishing reel capable of reliably preventing a reduction in meshing performance and durability of a gear housed therein.

  When the side frame is formed in a circular shape and the opening of the bulging portion that opens on the side frame side is closed with a closing plate fixed to the side frame, the side frame is formed with extremely high accuracy. Can do.

  1 to 4 show a fishing reel 10 according to a preferred embodiment of the present invention.

  The reel body 12 of the fishing reel 10 has a frame (frame body) 14 formed by a pair of left and right side frames 14a and 14b integrated with a support column 13 and the like, and each of the side frames 14a and 14b. The outer plates 16a and 16b are attached to the outside of the housing, formed as a housing, and fixed to the fishing rod via the attachment legs 18. The right side plate 16b is formed in a circular shape or a cylindrical shape, and the left side plate 16a is formed in a deformed shape in which a part of the cylindrical portion is bulged radially outward as shown in FIG. In the present specification, the left and right refer to the left and right on the paper surface of FIG.

  The spool 20 around which the fishing line is wound is rotatably supported between the left and right outer plates 16a and 16b, and a winding drive mechanism 22 that rotates the spool 20 is partitioned by the left plate 16a and the left frame 14a. It is accommodated in the internal space of the gear box G. In the inner space of the gear box G, in addition to the winding drive unit 22, the cylindrical body is guided by a guide shaft (not shown) that rotates in conjunction with the winding drive mechanism 22 and extends between the side frames 14 a and 14 b. Various members such as a level wind mechanism and a drag mechanism are accommodated in which the line guide 26a is reciprocated left and right on 26 and the fishing line is evenly wound on the spool 20.

  The spool 20 of this embodiment is supported by a spool shaft 20a that penetrates the side frames 14a and 14b of the reel body 12, and both ends of the spool shaft 20a are reels via ball bearings 30a and 30b, for example. The main body 12 is rotatably supported and rotates together with the spool 20. An end projecting from one end side of the spool shaft 20a through the left frame 14a is formed as a pinion shaft 32a that is integrally and coaxially arranged with the spool shaft 20a, and is rotated by a handle 34 on the pinion shaft 32a. The driven pinion 32 is movably supported.

  The pinion 32 has a cylindrical structure through which the pinion shaft 32a is inserted, and is rotatable with respect to the reel body 12 and movable in the axial direction by a bearing (not shown) supported by the left frame 14a and the left plate 16a. It is supported by. By turning the clutch mechanism ON / OFF via a clutch lever (not shown), the pinion 32 is engaged with the spool shaft 20a and rotates together with the spool shaft 20a, and the relationship between the spool shaft 20a and the engagement position. It is possible to move along the pinion shaft 32a between the non-engagement position where the combined state is released.

  The movement of the pinion 32 can be performed by moving the yoke 36 that engages with the circumferential groove 32b of the pinion 32 along the pinion shaft 32a in conjunction with the ON / OFF operation of the clutch mechanism. When the handle 34 is rotated in the clutch OFF state where the can be freely rotated, the clutch is returned to the ON state, and the fishing line can be wound around the spool 20. In the present embodiment, the pinion shaft 32a can be pressed via the adjusting screw 17 disposed on the left side plate 16a, and the frictional force acting on the spool shaft 20a can be adjusted.

  Further, in the gear box G, a handle shaft 34a having a handle 34 attached to one end with a tightening nut 33 is disposed in parallel with the pinion shaft 32a. By rotating the hand 34, the take-up drive mechanism 22 is provided. Thus, the spool 20 is driven to rotate. The tightening nut 33 is preferably prevented from rotating by a rotation stopper 33a fixed to the handle 34 with a small screw or the like.

  The handle shaft 34a is rotatably supported on the left frame 14a and the left plate 16a by bearings 35 (only the left frame 14a side is shown). A bearing that supports the handle shaft 34a on the handle 34 side is provided in a protruding portion 38 that protrudes in a substantially cylindrical shape on the left side plate 16a. In the protruding portion 38, the handle shaft 34a extends in the direction of winding the fishing line. A one-way clutch is provided that allows rotation and prevents reverse rotation.

  As shown in FIG. 4, the bearing 35 that supports the handle shaft 34a is held in the left frame 14a by a retaining plate 35a to facilitate the assembly and maintenance of various members in the gear box G. In order to prevent such a retaining plate 35a from being interfered with other members and to be easily and quickly mounted, the left frame 14a is engaged with at least a part of the outer shape of the retaining plate 35a. It is preferable to form the part 15 and prevent it from rotating together with the mounting small screw 35b. In this embodiment, the locking portion 15 is formed on the side surface of a recess that accommodates at least a part of the retaining plate 35a, and when the machine screw 35b is fastened to the left frame 14a, the edge of the locking plate 35a Lock the part. When fixing with two small screws 35b, it is preferable to prevent co-rotation in the tightening direction of each small screw 35b.

  Furthermore, the handle shaft 34a is rotatably mounted with a drive gear 22a that forms part of the take-up drive mechanism 22 together with the drag mechanism. By rotating the star drag 40 with the handle shaft 34a, the handle shaft The frictional coupling force of the drive gear 22a with respect to 34a can be changed and adjusted to a desired drag force. As a result, the driving force generated by the rotating operation of the handle 34 is transmitted to the drive gear 22a via the drag mechanism, and is transmitted from the drive gear 22a to the spool 20 via the pinion gear 32 and the spool shaft 20a. When the fish catches, if the force that rotates the spool 20 in the direction of releasing the fishing line exceeds the drag force, the drive gear 22a rotates against the drag force, and the spool 20 rotates in the direction of feeding the fishing line, and breaks the line. To prevent.

  This fishing reel 10 has a larger drive gear 22a to reduce the outer diameter of the reel body 12 and improve the rotation transmission efficiency in order to improve the casting operation and the fishing line winding operability. is there.

  For this reason, the outer peripheral part of the left side frame 14a and the left side plate 16a forming the gear box G causes the part surrounding the drive gear 22a to bulge radially outward with respect to the cylindrical part 42 surrounding the spool shaft 20a. The bulging portion 44 is formed as a deformed peripheral wall, and the outer peripheral portion of the drive gear 22 a is accommodated in the bulging portion 44.

  In the present embodiment, the cylindrical portion 42 is formed by the peripheral wall 42a integral with the left side plate 16a, and the bulging portion 44 is formed by the peripheral wall 44a integral with the left side frame 14a. A peripheral rib 44b corresponding to the bulging portion 44 is formed on the left side plate 16a, and a peripheral rib 42b corresponding to the cylindrical portion 42 is formed on the left side frame 14a. The peripheral rib 44b and the peripheral wall 42a of the left side plate 16a form a stepped end surface on the left side frame 14a, and the peripheral wall 44a and the peripheral rib 42b of the left side frame 14a form a stepped end surface on the left side plate 16a side. To do. The end faces of the peripheral walls 42a and 44a and the end faces of the peripheral ribs 42b and 44b are preferably arranged in a plane perpendicular to the spool shaft 20a.

  Thus, between the two members of the left side frame 14a and the left side plate 16a whose end surfaces are formed in a stepped shape, the peripheral wall of the left side frame 14a is the bulging side portion including the bulging portion 44 when assembled. A first mating portion T1 is formed so that 44a faces the peripheral rib 44b of the left side plate 16a, and further, a second mating portion T2 is formed at the cylindrical portion side, that is, the anti-bulging side portion. Specifically, the first mating portion T1 is formed at a portion including the end face of the peripheral rib 44b of the left side plate 16a and the end face of the peripheral wall 44a of the left side frame 14a. The second mating portion T2 is formed by the end face of the peripheral rib 42b of the left side frame 14a and the end face of the peripheral wall 42a of the left side plate 16a. The first and second mating portions T1 and T2 are formed in a step shape along the axial direction of the spool shaft 20a. In this embodiment, as shown in FIG. 4, the second mating portion T2 is formed over a wider angular range than the first mating portion T1.

  The left side frame 14a and the left side plate 16a forming the first and second mating portions T1 and T2 by the stepped end face arrangement are the second mating portion T2, and in this embodiment, there are a plurality of three The screw 46 is integrally fastened and fixed. Therefore, as shown in FIG. 3, three insertion holes 46a (only one is shown) through which the screws 46 are inserted are formed along the peripheral wall 42a forming the cylindrical portion 42 of the left side plate 16a. Further, as shown in FIG. 4, three screw holes 48 into which the screws 46 are screwed are formed along the peripheral rib 42b that forms the cylindrical portion of the left frame 14a. The bulging portion 44 is not provided with such an insertion hole or screw hole.

  The fishing reel 10 thus formed is assembled with various members such as a winding mechanism 22, a drag mechanism, and a level wind mechanism in the gear box G, and the positions of the pinion shaft 32a and the handle shaft 34a are respectively set. The left side plate 16a is mounted on the left side frame 14a while being aligned with the bearing portion.

  Thereafter, each screw 46 is inserted into the insertion hole 46a of the left side plate 16a, and is tightened and fixed to the screw hole 48 of the left side frame 14a. At the anti-bulge side portion, the end surface of the peripheral wall 42a forming the cylindrical portion 42 and the end surface of the peripheral rib 42b are in close contact with each other and are fastened and fixed. As a result, the left side plate 16a is positioned with high accuracy with respect to the left side frame 14a, and the high accuracy concentricity of the spool shaft 20a and the bearing 30a that supports the spool shaft 20a and the handle shaft 34a and the bearing 35 that supports the spool shaft 20a is ensured. Various members arranged in the gear box G can be accurately positioned.

  Such a high-precision positioning and fixing of the left side plate 16a with respect to the left side frame 14a is achieved by consolidating the tightening force by the screw 46 on one mating portion T2 side and using it as a reference surface for tightening and fixing. It is possible to prevent a decrease in accuracy (deformation such as tilt and deflection) due to the influence of tolerance on the T1 side, manufacturing error and the like.

  The fishing reel 10 formed in this way forms a bulging portion that accommodates the outer peripheral portion of the drive gear 22a on the outer peripheral portion of the gear box G of the winding drive mechanism 22 formed by the left frame 14a and the left plate 16a. By doing so, the large-sized drive gear 22a can be accommodated while being compact, and one of the second and second mating portions T1, T2 is formed on the second cylindrical portion 42. The left frame 14a and the end surface of the left side plate 16a are tightly fastened and fixed integrally with a plurality of screws 46 as a reference surface for tightening and fixing the mating portion T2 side, thereby contacting the other first mating portion T1 side. A fishing lie in which the reel main body 12 is formed into a strong integrated structure without being affected by variations in dimensions on the surface, and can reliably prevent a reduction in meshing performance and durability of the gear accommodated therein. It is possible to form a 10.

  5 and 6 show a fishing reel 10 according to another embodiment. In addition, since this embodiment is also basically the same as the above-described embodiment, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted. An embodiment is shown.

  In the present embodiment, the peripheral wall 44a of the bulging portion 44 is formed on the left side plate 16a, and the cylindrical portion 42 is a cylindrical peripheral wall 42a formed on the left side plate 16a at the anti-bulging side portion as described above. A second mating portion T2 is formed between the end surfaces of the peripheral ribs 42 formed on the left frame 14a. The first mating portion T1 is formed between the end surfaces of the peripheral wall 44a of the bulging portion formed on the left side plate 16a and the peripheral rib 44b formed on the left side frame 14a. The peripheral ribs 44b of the left frame 14a are formed only at portions adjacent to the cylindrical portion 42, that is, only at both ends of the bulged portion 44. The outer shape of the left frame 14a is viewed from the side (in the direction of the spool axis). ) To form a circular shape.

  Since the left frame 14a is circular, the peripheral wall 44a of the left plate 16a that forms the bulged portion 44 is formed with an opening that opens to the left frame 14a. The opening is closed by a closing plate 50 disposed between the inner ends (ends on the bulging portion 44 side) of the peripheral ribs 44b and 44b of the left frame 14a. The closing plate 50 is fixed to the left frame 14a with, for example, three screws 52, and its outer peripheral edge abuts against the inner peripheral surface of the peripheral wall 44a, or is opposed to it with a very slight gap. Is preferred.

  When the closing plate 50 is fixed to the left frame 14a with screws 52, the surface on the left plate 16a side is preferably arranged in the same plane as the end surface of the peripheral rib 44b of the left frame 14a. For this reason, the peripheral wall 44a of the left side plate 16a that forms the bulging portion starts to bulge outward in the radial direction from a portion corresponding to the peripheral rib 44b, and at least the inner periphery of the peripheral wall 44a is the inner end of the peripheral rib 44b. Preferably, they are formed in a matching state.

  As described above, the left frame 14a is formed in a circular shape in a side view, and the opening of the bulging portion 44 formed by the peripheral wall 44a is closed by the closing plate 50, so that the bulging portion having an irregular shape is formed on the left frame 14a. The left frame 14a can be formed with extremely high accuracy.

  In each of the above-described embodiments, the bulging portion 44 has a large-diameter arc-shaped convex portion that accommodates the peripheral portion of the drive gear 22a, and a smaller-diameter arc-shaped convex portion than the cylindrical portion of the level wind mechanism. It is obvious that the bulging portion 44 may be formed in a cylindrical shape having the same diameter as that of the cylindrical portion 42 or a cylindrical shape having a different diameter. is there.

  Further, the embodiment in which the gear box G is formed by the left frame 14a and the left plate 16a has been described as an example. However, such a gear box G may be formed by the right frame 14b and the right plate 16b. It is the same.
