Description

  The present invention relates to a reel leg fixing device mounted on a fishing rod and capable of attaching various fishing reels.

  Conventionally, for example, as disclosed in Patent Document 1, a moving hood and a fixed hood that are separated in the axial length direction are provided, and one end of the reel leg is inserted into the fixed hood and the other end of the reel leg is moved in the axial direction. 2. Description of the Related Art A reel leg fixing device of a type that fixes a fishing reel by pressing with a moving hood is known. In this case, the fixed hood and the movable hood are disposed on a pipe-shaped reel seat that is attached to the outer periphery of the fishing rod of the fishing rod, and the movable hood is rotated by rotating an operation nut disposed adjacent to the movable hood. Is moved to / from the fixed hood, whereby the fishing reel is attached / detached. Usually, the moving hood (hereinafter also referred to as the hood portion) of the reel leg fixing device is often made of a metal material, and a pad portion made of a synthetic resin is arranged on a portion (inner surface of the hood portion) where the reel leg to be inserted comes into contact. I try to set it up.

  By the way, recently, it has been demanded to reduce the weight of a fishing rod, and forming the hood portion with a metal material as described above hinders weight reduction. For this reason, for example, Patent Document 2 discloses that the hood portion is formed of a synthetic resin.

Japanese Utility Model Publication No.57-187064 JP 2009-65868 A

  As described above, the reel leg fixing device causes the moving hood to approach / separate the fixed hood by rotating an operation nut disposed adjacent to the moving hood. The top end of the operating nut is connected to the base end of the moving hood, and when the operating nut is rotated in the tightening direction, it is moved to the fixed hood without rotating the moving hood, and the operating nut is When rotating in the loosening direction, the moving hood is moved in a direction away from the fixed hood without rotating. In this case, the connection between the distal end portion of the operation nut and the proximal end portion of the moving hood generally forms an annular recess at the distal end portion of the operation nut 18 as disclosed in Patent Document 2, This is achieved by engaging a bent hook-shaped locking projection provided in an annular shape at the base end of the moving hood into the recess.

  Therefore, a large pressing force acts on such a connecting portion between the operation nut and the moving hood when the operation nut is tightened and the reel leg is pressed between the moving hood and the fixed hood. When pulling the moving hood away from the fixed hood by loosening the operation nut from the attached state, a large tensile force acts. Such a force causes stress concentration in the connecting portion, in particular, the bent portion of the hook-shaped locking projection of the moving hood, and causes the moving hood to undergo deformation in the expanding direction that causes the locking projection to be detached from the recessed portion. Attempts to cause to the proximal end of the.

  Therefore, when the moving hood is formed of a synthetic resin as disclosed in Patent Document 2 described above, it is necessary to ensure sufficient strength with this connecting portion, in particular, the locking protrusion of the moving hood. That is, when the moving hood is formed of resin for weight reduction, it is indispensable to ensure sufficient strength at such a connecting portion that easily causes stress concentration, otherwise the connecting portion (especially moving) In some cases, the hood locking projection) may cause breakage. However, if the wall thickness is too large to ensure strength, the weight will increase and the result will be the reverse of the trend of weight reduction. That is, it is desirable to reduce the thickness as much as possible even in the weight reduction, and an efficient and effective weight reduction including securing of strength is desired.

  The present invention has been made paying attention to the above-mentioned problems, and effectively and efficiently reduces the thickness and weight of the moving hood while ensuring sufficient strength at the connecting portion between the operation nut and the moving hood. It is an object of the present invention to provide a reel leg fixing device that can be achieved in an effort.

  In order to achieve the above-described object, the present invention moves a cylindrical moving hood having a bulging portion that bulges so as to form an opening that can accommodate a reel leg of a fishing reel in an axial direction by an operation nut. A reel leg fixing device for engaging the operating nut and the moving hood by engaging a bent locking portion provided at an end of the moving hood with a recess in the end of the operating nut. In the reel leg fixing device, the moving hood is formed of a fiber reinforced resin material in which a reinforcing fiber is impregnated with a synthetic resin, and at least the reinforcing fiber oriented in the axial direction is at least a connecting portion between the operation nut and the moving hood. It is characterized by extending continuously.

  According to the reel leg fixing device having the above configuration, the moving hood is formed by the fiber reinforced resin material in which the reinforcing fiber is impregnated with the synthetic resin. Therefore, the strength is improved as compared with the case where the moving hood is formed only by the synthetic resin. Therefore, it is possible to reduce the thickness while securing the necessary and sufficient strength. That is, with respect to the moving hood, it is possible to effectively and efficiently reduce the thickness and weight while securing sufficient strength.

  In the above configuration, the reinforcing fiber oriented at least in the axial direction continuously extends at least at the connecting portion between the operation nut and the movable hood, which is likely to cause stress concentration, so that sufficient strength can be secured at the connecting portion. Damage can be avoided at the part. That is, when the reinforcing fibers oriented in the axial direction are not continuous at the connecting portion, specifically, for example, two or more layers of reinforcing fibers oriented in the axial direction at the connecting portion (particularly the bent portion) are provided in the radial direction. When the operation nut is tightened or loosened, the layer separated in the radial direction by the outward force based on the above-mentioned inherent pressing force or tensile force acting on the moving hood when the operation nut is tightened or loosened Although there is a possibility that the two may break along the axial direction at the interface, in the above configuration according to the present invention, the reinforcing fibers oriented in the axial direction are connected to the connecting portion in order to resist such action force inherent to the connecting portion. Therefore, such a breakage can be effectively prevented. In addition, since the continuous axial fiber extends in the circumferential direction (radial direction) at the bent portion, the continuous reinforcing fiber extends in both the axial direction and the circumferential direction in the entire connecting portion, and axial force and twist A highly rigid connecting part that is strong against force can be realized.

  According to the present invention, there is provided a reel leg fixing device capable of effectively and efficiently reducing the thickness and weight of the moving hood while ensuring sufficient strength at the connecting portion between the operation nut and the moving hood. It will be obtained.

The structure which is not about the intermediate collar 5 may be sufficient, and the structure which 4 or more are joined may be sufficient. In addition, the fishing rod is not particularly limited in its configuration, such as a single rod, a swing rod, and a through rod, in addition to the side-by-side type.

  The main rod 3 is provided with a reel leg fixing device 10 on which a fishing reel 70 is mounted, and each rod is provided with a plurality of guides for guiding a fishing line fed from the fishing reel at a predetermined interval. A fishing line guide 8 (a tip guide 8a at the tip of the tip rod 7) is attached. The fishing line guide 8 may be configured as a fixed guide that is fixed to the rod or may be configured as an idle guide that can slide along the rod.

  Genroku 3, middle 5 and tip 7 are made of a fiber reinforced resin material in which a reinforcing fiber (for example, carbon fiber or glass fiber) is impregnated with a synthetic resin such as an epoxy resin, It is configured as a tubular body or a solid body.

  The reel leg fixing device 10 provided on the main rod 3 includes a fixed hood and a moving hood that moves in the axial direction. With the reel leg of the fishing reel inserted into the fixed hood, the moving hood is pivoted. The fishing reel is configured to be attached and detached by moving in the direction. In this case, the fixed hood may be on the tip side or on the proximal end side.

Hereinafter, the configuration of the reel leg fixing device 10 of the present embodiment will be described in detail with reference to FIGS.
The reel leg fixing device 10 includes a reel sheet main body (hereinafter simply referred to as a main body) 11 formed in a cylindrical shape that is externally fitted to the main shaft 3. The main body 11 is integrally formed of, for example, synthetic resin, and includes a mounting surface 12 on which the reel legs 71 of the fishing reel 70 are mounted, and a fixed hood 13 disposed on the tip side of the mounting surface 12. And a moving hood 15 disposed on the base end side of the mounting surface 12.

  The fixed hood 13 includes a hood portion 13A that is integrally formed with the main body 11 and bulges so as to accommodate the front end side leg portion 71a of the reel leg 71. The front end side leg portion 71a of the reel leg 71 has a hood portion. It is inserted through the opening 13a of 13A. The hood portion 13 </ b> A may be formed separately from the main body 11 and integrated with the main body 11, similarly to the hood portion of the moving hood described later.

  The movable hood 15 is configured to be movable along the axial direction, and includes a hood portion 15 </ b> A formed as a separate body from the main body 11. The hood portion 15A of the present embodiment includes a bulging portion 15a that bulges so as to accommodate the base end side leg portion 71b of the reel leg 71, and a cylindrical portion 15b that is integrally formed on the base end side of the bulging portion 15a. It has. That is, the bulging portion 15a has a shape that gradually rises as the arc region of a predetermined range on the outer periphery of the cylindrical portion 15b moves to the tip side, and the proximal end leg portion 71b of the reel leg 71 It is inserted through the opening 15c of the bulging portion 15a.

  A pad member 16 is disposed inside the bulging portion 15a so as to be in pressure contact with the surface of the base end side leg portion 71b of the reel leg 71 to be inserted. The pad member 16 is a portion that is pressed against the surface of the base end side leg portion 71b of the reel leg 71 when the moving hood 15 is moved toward the fixed hood 13, and has a function of firmly fixing the reel leg 71. Have That is, the pad member 16 is formed in a shape corresponding to the surface of the base end side leg portion 71 b of the reel leg 71, and the projection 16 a is fitted into the hole 15 d formed in the bulging portion 15 a of the moving hood 15. By doing so, it is integrated with the inner surface of the bulging portion 15a.

  A male screw portion 11a is integrally formed on the base end side of the main body 11, and an operating nut 18 that moves along the axial direction by being rotated is screwed into the male screw portion 11a. The front end of the operation nut 18 is connected to the movable hood 15 (the cylindrical portion 15b of the hood portion 15A). The connection relationship here is that when the operation nut 18 is rotated in the direction of tightening, the moving hood 15 is moved to the fixed hood side without rotating, and the operation nut 18 is rotated in the direction of loosening. What is necessary is just to move the moving hood 15 in the direction away from the fixed hood 13 without rotating it.

  Specifically, as shown in FIG. 4A, an annular protrusion 18a is formed on an end edge 18e of the operation nut 18 on the cylindrical portion 15b side, and a locking protrusion 18f protruding radially outward is formed at the tip. As a result, an annular recess 18g is formed on the outer peripheral surface of the distal end portion of the operation nut 18, and the end (base end edge) 15e on the operation nut 18 side of the cylindrical portion 15b of the moving hood 15 is radially inward. An annular locking projection 15f is formed as a locking portion that is bent into a hook-like shape projecting into the hook, and the locking projection 15f is locked to the recess 18g, whereby the operation nut 18 and the movable hood 15 are connected. The connecting portion is indicated by reference numeral 20 in FIG.

  According to the engagement (connection) relationship between the operation member 18 and the hood portion 15A (cylindrical portion 15b), when the operation nut 18 is rotated in the tightening direction, the operation nut 18 is screwed toward the fixed hood 13 side. At the same time, the moving hood 15 (cylindrical portion 15b of the hood portion 15A) is moved toward the fixed hood 13 by the contact relationship between the end edge 18e and the end edge 15e without rotating. That is, the reel leg 71 placed on the placement surface 12 is fastened and fixed between the fixed hood 13 and the movable hood 15. When the operation nut 18 is rotated in the loosening direction, the operation nut 18 is screwed away from the fixed hood 13 and the moving hood 15 (cylindrical portion 15b of the hood portion 15A) does not rotate, but the locking projection. It is moved in a direction away from the fixed hood 13 by the engagement relationship between 15f and the recess 18g. That is, the reel leg 71 placed on the placement surface 12 can be detached from the fixed hood 13 and the movable hood 15.

  The moving hood 15 (hood portion 15A) having the above configuration is a fiber reinforced resin material in which a reinforced fiber (for example, carbon fiber or glass fiber) is impregnated with a synthetic resin so that a certain strength is maintained and the weight can be reduced. In this embodiment, it is formed of a prepreg sheet 40 as shown in FIG. In this case, in the prepreg sheet 40, the reinforcing fibers are aligned at least in the axial direction (which may include a circumferential direction that forms 90 ° with respect to the axial direction and an inclined direction that forms an angle of less than 90 ° with respect to the axial direction). Sheet or reinforced fiber knitted sheet, thermoplastic resin (for example, nylon, polypropylene, polyphenyl sulfide, thermoplastic polyurethane) or thermosetting resin (for example, epoxy resin, phenol resin) , Polyester resin) as a matrix resin.

  FIG. 5 shows a first example of a method for forming the moving hood 15, and FIG. 5A is a schematic perspective view showing a state where the prepreg sheet 40 forming the moving hood 15 is to be wound around the mandrel 50, (B) is a sectional side view of the mandrel 50 around which the prepreg sheet 40 is wound. The movable hood 15 is formed by winding the prepreg sheet 40 around a mandrel 50 formed in a predetermined shape, heating the prepreg sheet 40 to cure the synthetic resin, and then removing the mandrel 50 from the core. In FIG. 5 (same in all subsequent figures), the reinforcing fibers 42 aligned in the axial direction are schematically shown. The mandrel 50 has a large-diameter cylindrical portion 50a and a small-diameter cylindrical portion 50b so as to have a step 52 for forming the bent portion 44 of the locking projection 15f of the moving hood 15 corresponding to the connecting portion 20.

  Here, the prepreg sheet 40 forming the axial length direction fiber layer is such that at least the reinforcing fiber 42 oriented in the axial direction continuously extends at least at the connecting portion 20 between the operation nut 18 and the movable hood 15 ( For example, the reinforcing fibers 42 oriented in the axial direction extend continuously without being interrupted over substantially the entire length of the moving hood 15), and those having a predetermined length are prepared, and the mandrel 50 so as to straddle the step 52 of the mandrel 50. Wound around. In this case, the base end edge 40a of the prepreg sheet 40 may be aligned on the mandrel 50 so as to be longer than the base end of the actual moving hood 14 (the end on the connecting portion 20 side). In that case, after the mandrel is decentered, it is cut to a required length along a cutting line C1 (C2) as shown in FIG.

  When the prepreg sheet 40 is wound around the mandrel 50 in this manner, the reinforcing fiber 42 is bent at the step 52 by winding a fastening tape (not shown) around the outer periphery of the prepreg sheet 40 and fastening the prepreg sheet 40. Thus, a bent portion 44 as shown in FIG. 5B is formed. Finally, after heating to cure the synthetic resin, the mandrel 50 is decentered, and the prepreg sheet 40 is cut as necessary.

  In addition, when the prepreg sheet 40 has only reinforcing fibers extending in the axial direction, the reinforcing fibers are, for example, on the outer side or the inner side of the prepreg sheet 40, for example, in the circumferential direction (or less than 90 ° with respect to the axial direction). For example, a circumferential fiber layer (an oblique fiber layer, for example, a woven fabric fiber layer) may be obtained by winding a prepreg sheet (not shown) aligned in the axial direction. May be arranged at least.

  FIG. 6 shows a second example of the method for forming the movable hood 15, and FIG. 6A is a schematic perspective view showing a state where a prepreg sheet forming the movable hood is to be wound around a mandrel. b) is a perspective view of a mandrel around which a prepreg sheet is wound. In this molding method, a mandrel 50A having a constant diameter is used over the entire length, and substantially corresponds to the length of the locking projection 15f on the base end edge 40a of the prepreg sheet 40 as shown in FIG. A plurality of slits 47 having a predetermined length are provided at predetermined intervals (in this embodiment, the slits 47 are provided at equal intervals over the entire circumference of the base end of the movable hood 15 constituting the connecting portion 20), and the prepreg sheet 40 Is bent around the mandrel 50A by using the slit 47 to bend the base end of the prepreg sheet 40 against the base end surface 50Aa of the mandrel 50A as shown in FIG. 6B. 44 may be formed (for example, it may be performed by winding a fastening tape as described above). Thereafter, this is heated to cure the synthetic resin, and then the mandrel 50A is decentered.

  In FIG. 7, at least a portion corresponding to the connecting portion 20 is formed by the forming method of FIG. 5 and cut by a cutting line C1 (see FIG. 5B) or moved by the forming method of FIG. A perspective view ((a) of FIG. 7) and a side sectional view ((b) of FIG. 7) in which the hood 15 is connected (coupled) to the operation nut 18 are shown. Since this connected state has already been described in relation to FIG. 4B, it will not be described here.

  As can be seen from FIG. 7B, the moving hood 15 has at least a reinforcing fiber 42 oriented in the axial direction at least at the connecting portion 20 between the operation nut 18 and the moving hood 15 (for example, over almost the entire length of the moving hood 15). ) Continuously extending without interruption. In this case, the reinforcing fiber 42 oriented at least in the axial direction swells from the distal end of the locking projection 15f (the end surface facing the radially inner side at the base end of the moving hood 15) via the bent portion 44 of the locking projection 15f. It extends continuously without interruption toward the protruding portion 15a.

  As described above, according to the reel leg fixing device 10 of the present embodiment, the moving hood 15 is formed by the fiber reinforced resin material in which the reinforcing fiber is impregnated with the synthetic resin. The strength can be improved as compared with the case of forming, and therefore it is possible to reduce the thickness while securing a necessary and sufficient strength. That is, the movable hood 15 can be effectively and efficiently reduced in thickness and weight while ensuring sufficient strength.

  Moreover, in this embodiment, since the reinforcing fiber 42 oriented at least in the axial direction continuously extends at the connection portion 20 between the operation nut 18 and the movable hood 15 that easily causes stress concentration, the connection portion 20 is sufficient. The strength can be ensured, and damage or the like can be avoided at the connecting portion 20. That is, when the reinforcing fibers 42 oriented in the axial direction are not continuous at the connecting portion 20, specifically, for example, the layer of reinforcing fibers oriented in the axial direction at the connecting portion 20 (particularly the bent portion 44) is in the radial direction. When the operating nut 18 is tightened or loosened, a radial outward force based on a specific pressing force or tensile force acting on the moving hood 15 when the operating nut 18 is tightened or loosened. There is a possibility that the layers separated by the line may break along the axial direction at the interface. However, in the configuration of this embodiment, in order to resist such an action force unique to the connecting portion 20, the reinforcement directed in the axial direction. Since the fiber 42 extends continuously at the connecting portion 20, such breakage can be effectively prevented. In addition, since the continuous axial fibers extend in the circumferential direction (radial direction) in the bent portion 44 (see FIG. 7B), the continuous reinforcing fibers in the entire connecting portion 20 are in the axial direction and the circumferential direction. (Particularly in the second embodiment shown in FIG. 8 to be described later, this tendency is significant), and a highly rigid connecting portion strong against axial force and torsional force can be realized.

  FIG. 8 shows a side sectional view of the movable hood 15 of the reel leg fixing device according to the second embodiment of the present invention and the operation nut 18 connected thereto. As shown in the figure, in this embodiment, the moving hood 15 is formed by the manufacturing method of FIG. 5 by at least a portion corresponding to the connecting portion 20 by cutting the prepreg sheet 40 along the cutting line C2 of FIG. Has been. That is, in the present embodiment, the recess 18g ′ of the operation nut 18 is formed longer in the axial direction than the recess 18g of the first embodiment, and the movable hood 15 is latched correspondingly to the recess 18g ′. The protrusion 15f ′ is also formed so that the base end side from the bent portion 44 is long in the axial direction. Even in such a configuration, the same effects as those of the first embodiment can be obtained, and the connection state (locking state) of the connection portion 20 can be further strengthened, and the rigidity of the connection portion 20 can be further increased.

FIG. 9 shows a side sectional view of the movable hood 15 of the reel leg fixing device according to the third embodiment of the present invention and the operation nut 18 connected thereto. As shown in the drawing, in the present embodiment, a reinforcing member 60 that suppresses deformation of the movable hood 15 in the radially outward direction at the connecting portion 20 is provided on the outer periphery of the fiber reinforced resin material positioned at the connecting portion 20. Specifically, a metal ring-shaped member (metal ring) is formed on the outer periphery (the proximal end side of the bent portion 44) of the locking projection 15f ′ of the movable hood 15 according to the second embodiment. A reinforcing member 60 is fitted, and the reinforcing member 60 has a function of suppressing the deformation of the prepreg sheet 40 in this portion, particularly the deformation outward in the radial direction. That is, by arranging the reinforcing member by such a ring-shaped member, stress concentration does not occur at the site of the connecting portion, and the locking projection 15f ′ is prevented from being detached from the recess 18g ′. The reinforcing member 60 may be made of a prepreg sheet having reinforcing fibers oriented in the circumferential direction instead of a metal ring. The prepreg sheet having such circumferentially oriented reinforcing fibers can also effectively suppress deformation of the prepreg sheet 40 toward the radially outer side.

As shown in the figure, also in the present embodiment, a reinforcing member 62 that suppresses the deformation of the movable hood 15 in the radially outward direction at the connecting portion 20 is provided on the outer periphery of the fiber reinforced resin material positioned at the connecting portion 20. Specifically, the reinforcing member 62 made of a metal ring is provided on the outer periphery of the locking projection 15f of the movable hood 15 according to the first embodiment (on the front end side of the bent portion 44 (side toward the bulging portion 15a)). The reinforcing member 62 also prevents deformation of the prepreg sheet 40 in the radial direction of the prepreg sheet 40 so that stress concentration does not occur in this portion. The separation of the protrusion 15f is also prevented. The reinforcing member 62 may be made of a prepreg sheet having reinforcing fibers oriented in the circumferential direction instead of a metal ring.

  FIG. 11 shows a side sectional view of the movable hood 15 of the reel leg fixing device according to the fifth embodiment of the present invention and the operation nut 18 connected thereto.

Yes. Therefore, the reinforcing member 64 has a cylindrical portion 64 a that extends in the axial direction on the distal end side of the bent portion 44, and a bent flange 64 b that extends radially inward from the bent portion 44. Such a reinforcing member 64 suppresses deformation of the prepreg sheet 40 at the outer side in the radial direction and the outer side in the axial direction so that stress concentration does not occur in the portion, and therefore, the locking protrusion from the recess 18g. 15f separation is also prevented. The reinforcing member 64 may be made of a prepreg sheet having carbon fibers oriented in the circumferential direction instead of a metal ring.

After the molding, the Teflon (registered trademark) tape 67 is removed from the prepreg sheet 40, whereby an annular recess into which the locking projection 18 f of the operation nut 18 enters is left on the inner surface of the prepreg sheet 40.

  Such a reinforcing member 66 also suppresses deformation of the prepreg sheet 40 in the radial direction outside and in the axial direction outside of the prepreg sheet 40 so that stress concentration does not occur in this portion, and therefore, the locking protrusion from the recess 18g. 15f separation is also prevented.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously. For example, in the above-described embodiment, the form of the moving hood and the operation nut, the form of the locking projection and the recess, and the like are arbitrary. In short, at least the reinforcing fibers oriented in the axial direction are at least the operation nut and the movement hood. What is necessary is just to extend continuously in the connection part. Moreover, in each embodiment mentioned above, although the latching protrusion which protrudes to the radial inside of a movement hood was latched by the recessed part formed in the outer peripheral surface of an operation nut, the cyclic | annular form which protrudes to the radial direction outer side of a movement hood The locking protrusions may be reversed to be locked in an annular recess formed on the inner peripheral surface of the operation nut.
