Description

Bait holder and holder unit

Technical Field

The present invention relates to a bait holder for holding bait and a structure of a holder unit suitable for the bait holder.

Background

For example, in fishing hairtails, a bait holder called "Tenya" is attached to a hook assembly. Generally, a bait holder has: a head having a lead weight function; a holding portion that holds a bait (typically sardine or japanese herring); and a hook for hooking an object of attacking the lure (see patent document 1). The hook has a shaft portion, a shank and a hook tip curved portion, and a base end of the shaft portion is connected to the head portion in a state where the shank and the hook tip curved portion are directed downward.

A needle is projected from the shaft of the hook, and the needle is disposed so that the tip thereof faces upward. The needle has a winding for holding a bait. The holding portion is composed of the shaft portion, the puncture needle, and the winding. In actual fishing, a fisher inserts a sardine or a japanese silver herring as a bait on the needle and arranges the same on the shaft, and winds the coil around the bait in this state. Accordingly, the bait is fixed to the shaft portion and the pricking pin, and is held by the bait holder.

In order to improve the fishing result, the angler needs to quickly perform the bait loading and unloading operation in a time zone (so-called "suitable fishing time") in which the target foraging operation is frequent. However, the body of the sardine as the bait, particularly the body of the frozen or thawed sardine, is very fragile, and it is not easy to quickly perform the work of attaching the sardine to the bait holder with the above-described configuration. In particular, when the bait is replaced, that is, when the sardine is lost due to the attack of the target and the windings are entangled with each other, the operation of removing the sardine from the holding portion may be very troublesome.

In order to solve such a problem, a bait holder capable of quickly replacing a bait by a simple operation has been proposed in the related art (refer to patent document 2). The bait holder has a guard for supporting the sardine from the side, and the guard is provided on the shaft of the hook. In addition, the bait holder has an auxiliary arm. The auxiliary arm has a fixing pin for fixing the sardine, and is displaced between an approaching posture for approaching the shaft part from the upper side and a separating posture for separating from the shaft part to the upper side. When the auxiliary arm is displaced to the approaching posture, the fixing pin pierces the back of the sardine from above to fix the sardine. By displacing the auxiliary arm to the distant position, the sardine can be easily taken off from the shaft portion. That is, the protector can support the sardine as long as the fisher places the sardine on the shaft portion, and the fisher can easily attach and detach the sardine by operating the auxiliary arm.

Disclosure of Invention

[ problem to be solved by the invention ]

Further, the bait holder disclosed in patent document 2 is displaceable by elastic deformation of the auxiliary arm, and is engageable with the shaft portion. Therefore, when the bait holder is used for boat fishing targeting a large hairtail, if the angler strongly manipulates the hook assembly in the water, the auxiliary arm may be elastically deformed and come off the shaft. Further, since the auxiliary arm is formed of a bent metal wire, the fishing line is easily caught in the water by the auxiliary arm. As a result, when a plurality of anglers are on the same boat, the hook assembly of an adjacent angler may be entangled around the auxiliary arm.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bait holder which can reliably hold soft baits such as sardines and japanese silver-banded herrings by a simple operation and which is less likely to cause a fishing line to be entangled even when used for boat fishing or the like.

[ technical means for solving problems ]

(1) The present invention relates to a bait holder for holding a bait fish, which is suitable for a bait hook assembly, and comprises: a lead weight having a ring-shaped member connectable to a fishing line; a hook part having a straight shaft part fixed at one end to the weight, and a hook handle and a hook tip bending part continuous to the shaft part; a fixing needle which is provided so as to protrude from the shaft portion and which pierces a bait fish placed along the shaft portion; and a pair of holding pieces made of resin or rubber and configured to change a posture between a holding posture in which the pair of holding pieces approach each other in a state in which the fixing needle is disposed inside and an open posture in which the pair of holding pieces are spaced apart from each other by rotating with the shaft portion as a reference.

According to this configuration, the angler displaces the pair of grip pieces to the open posture, and arranges the bait fish along the shaft portion on the shaft portion. At this time, the fixing needle pierces the bait fish placed on the shaft portion, and therefore the bait fish is stably placed on the shaft portion. In this state, the pair of holding pieces are displaced to the holding posture. That is, the pair of holding pieces rotate with the shaft portion as a rotation reference, and the fixed needle and the bait fish are arranged inside and surrounded from the side. Since each of the holding pieces is not made of metal but made of resin or rubber, it is not easily deformed even when it is handled in water. Therefore, the bait fish can be reliably held, and the fisherman can be prevented from inadvertently dropping the bait fish. Furthermore, since the clamping piece is made of resin or rubber, the fishing line is not easily entangled. When a pair of holding pieces are displaced to an open posture, the holding pieces are away from the bait fish on the shaft portion, and therefore, a fisherman can quickly take off the bait fish for replacement.

(2) Preferably, an attitude holding mechanism for holding the pair of holding pieces in the holding attitude is disposed between the pair of holding pieces.

In this configuration, the pair of gripping pieces is held in the holding posture by the posture holding mechanism. Therefore, even if the hook assembly is violently operated during actual fishing, the holding piece can be reliably prevented from being displaced to the open posture.

(3) Preferably, the posture maintaining mechanism is a ratchet mechanism.

In this structure, the pair of gripping pieces is reliably held in the holding posture by a simple mechanism.

(4) Preferably, the holding piece has a window that exposes a body-side center portion of the bait fish when the holding piece is displaced to the holding posture.

In this configuration, the bait fish disposed on the shaft portion is largely exposed, and therefore, the presence of the bait can be strongly shown to the target fish.

(5) Preferably, the holding piece has an elongated rod-like abutting portion extending along the shaft portion to form an edge of the window, and abutting along the body-side back of the bait fish when the holding piece is displaced to the holding posture.

In this configuration, the abutting portion presses the body-side back portion of the bait fish, and therefore, the bait fish is further stabilized. Further, since the contact portion defines a part of the window, the window becomes large. Therefore, there is an advantage that the body side of the bait fish is more exposed.

(6) Preferably, the clamping piece is rotatably connected to the shaft portion via a plurality of connecting projections. In this case, it is preferable that at least one of the coupling projections has a long hole formed therethrough, and the hook-tip bent portion is inserted into the long hole in the longitudinal direction.

In this structure, the gripping piece smoothly rotates with respect to the shaft portion. Therefore, the clamping piece supported by the connecting projection can smoothly change the posture. Since the elongated hole is formed through the connecting projection, the hook-tip bending portion, the hook shank, and the shaft portion can be easily inserted into the elongated hole when the clamping piece is attached to the shaft portion. That is, even when the barb is formed at the hook-point bending portion, the hook portion can be easily inserted through the coupling projection, and the coupling projection can be reliably attached to the shaft portion.

(7) The following structure may be adopted: the clamping piece is rotatably connected to the shaft portion via a plurality of connecting projections, at least one of the connecting projections is formed with a groove which is open on a peripheral surface of the connecting projection, and the shaft portion is fitted into the groove from top to bottom in the vertical direction.

In this structure, the gripping piece smoothly rotates with respect to the shaft portion. Therefore, the clamping piece supported by the connecting projection can smoothly change the posture. Since the groove is formed in the coupling projection, the shaft portion enters the groove when the clamping piece is attached to the shaft portion. That is, the coupling projection can be easily and reliably attached to the shaft portion.

In actual fishing, the target bites the bait fish from below upward in many cases. Since the connecting projection is fitted to the shaft portion from below to above, the clamping piece is fitted to the hook portion from below to above. Therefore, even when the bait fish is caught by the object, the grip piece can be prevented from falling off from the hook portion by the collision.

(8) Preferably, one of the clamping pieces is fixed to the shaft portion, and the other clamping piece is configured to rotate with respect to the shaft portion.

In this configuration, the posture change can be easily performed by operating only the other of the pair of gripping pieces. Therefore, the bait fish can be quickly attached and detached during actual fishing.

(9) The holding unit according to the present invention is applied to a bait holder including: a lead weight having a ring-shaped member connectable to a fishing line; and a hook part having a straight shaft part fixed at one end to the weight, and a hook handle and a hook tip bending part continuous to the shaft part. The holder unit has: a pair of holding pieces made of resin or rubber that change their postures between a holding posture in which the pair of holding pieces approach each other and a bait fish is arranged inside and surrounded from the side and an open posture in which the pair of holding pieces are separated from each other by rotating on the basis of a predetermined connecting shaft; and a fixing portion provided on at least one of the pair of clamping pieces and detachably fitted to the shaft portion.

According to this configuration, the pair of clamping pieces are connected via the connecting shaft, and the fixing portion is fitted to the shaft portion. That is, the holder unit is attachable to and detachable from the bait holder. The angler displaces the pair of holding pieces to the open posture, and arranges the bait fish between the holding pieces. In this state, the pair of holding pieces are displaced to the holding posture. That is, the pair of holding pieces are rotated about the connecting shaft as a rotation reference, and the bait fish is arranged inside and surrounded from the side. Since each of the holding pieces is not made of metal but made of resin or rubber, it is not easily deformed even when it is operated in water. Therefore, the bait fish can be reliably held, and the fisherman can be prevented from accidentally dropping the bait fish. Furthermore, since the clamping piece is made of resin or rubber, the fishing line is not easily entangled. When a pair of holding pieces are displaced to an open posture, the holding pieces are far away from the bait fish, so that a fisherman can quickly take off the bait fish for replacement.

[ Effect of the invention ]

According to the present invention, the angler can reliably fix the bait fish to the shaft portion or detach the bait fish simply and quickly by operating the pair of holding pieces to displace the pair of holding pieces to the holding posture or the open posture. Further, since the above-described grip piece makes the fishing line less likely to be entangled, it is possible to prevent the hook units from being entangled with each other in actual fishing. Furthermore, the clamping pieces are not easy to deform, so that the bait fish can be prevented from falling off due to deformation of the clamping pieces in actual fishing. In addition, when the pair of clamping pieces constitute a holder unit, the holder unit is detachable from the shaft portion. Therefore, the holder unit suitable for the size of the bait fish can be attached to the shaft portion.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings as appropriate. It should be noted that this embodiment is only one embodiment of the bait holder according to the present invention, and it goes without saying that the embodiment may be modified within a range not changing the gist of the present invention.

< overall Structure and gist >

The bait holder 10 is typically mounted on a fishing hook assembly for fishing hairtails, also known as "hairtail heaya" between anglers. As shown in the drawing, the bait holder 10 includes a sinker 11, a hook portion 12, fixing pins 13 and 14, and a pair of holding

pieces

15 and 16 whose postures are changed as described later. Although not shown, for example, frozen sardine or the like is used as a bait fish and is disposed on the hook portion 12. At this time, the fixing needles 13, 14 pierce the bait fish to stabilize the bait fish.

Fig. 2 and 3 are perspective views of the bait holder 10, showing the posture change of the

gripping pieces

15 and 16. In the same drawing, illustration of the fixing pin 14 is omitted.

As shown in these figures, the lead plummet 11 is constructed of metal (typically lead). The weight 11 is set to a predetermined weight so that the hook assembly is stably submerged. The shape of the lead weight 11 is not particularly limited, and in the present embodiment, it is molded to follow the head of a small fish. A ring 17 is formed at the upper end of the plummet 11. The ring-shaped member 17 is formed of a metal wire (typically, stainless steel) and is formed in a ring shape. A fishing line is connected to the ring-shaped member 17.

The hook portion 12 functions as a hook that penetrates into a target (hairtail) when the target strikes the bait fish. As shown in FIGS. 1 to 3, the hook 12 has a shaft 18, a shank 19 and a hook tip bending part 20. These are made of a metal wire (typically, stainless steel) and are integrally formed. In fig. 1, the left-right direction is the "axial direction 22" of the shaft portion 18, the left side is defined as the "front" of the bait holder 10, the right side is defined as the "rear" of the bait holder 10, and the up-down direction is indicated by an arrow 24.

The shaft portion 18 is a straight rod-shaped member. A front end portion 21 (corresponding to "one end portion" in the claims) of the shaft portion 18 is fixed to a rear end portion of the plummet 11. The shaft portion 18 extends rearward in the axial direction 22. Bait fish is placed on the shaft portion 18 along the shaft portion 18.

The shank 19 is continuous with the other end 23 of the shaft portion 18 and is bent downward in the vertical direction 24 in the same drawing. The hook tip bend 20 is continuous with the hook shank 19. The hook tip curved portion 20 is curved such that the hook tip 25 thereof extends toward the front side of the axial direction 22. In addition, so-called barbs 26 are formed on the hook tips 25.

The fixing pin 13 is attached to the shaft portion 18. The fixing pin 13 is formed of a metal wire (typically, stainless steel) and formed in a C-shape. As shown in fig. 1, the fixing pin 13 has a base portion 27 and a pair of protruding portions 28. The base portion 27 is fixed to the shaft portion 18, and the spur portion 28 stands upward. The fixing pin 14 is also made of a wire material made of stainless steel or other metal, and is formed in an L-shape as shown in fig. 1. The base portion 29 of the fixed needle 14 is fixed to the shaft portion 18, and the protruding portion 30 rises upward. As shown in fig. 1, the protruding portion 30 of the fixing pin 14 is disposed in front of the shaft portion 18 in the vicinity of the weight 11. These fixing pins 13 and 14 may be omitted.

As shown in fig. 2 and 3, the clamping

pieces

15 and 16 are attached to the shaft portion 18. The bait holder 10 according to the present embodiment is characterized in that: the gripping

pieces

15 and 16 are rotatable about the shaft 18, and both of them change their postures between a closed posture (see fig. 2) and an open posture (see fig. 3); the holding

pieces

15 and 16 are mounted with a posture holding mechanism 31 described later; the nipping

pieces

15, 16 are made of resin (in the present embodiment, Polyamide (PA), Polyoxymethylene (POM), Thermoplastic Polyurethane (TPU), polypropylene (PP), Polyethylene (PE), or other resin) or rubber. The posture in which the holding

pieces

15 and 16 are closed as shown in fig. 2 is referred to as a "holding posture", and the posture in which the holding pieces are opened as shown in fig. 3 is referred to as an "open posture". The holding

pieces

15 and 16 change their postures with the fixing needles 13 and 14 disposed inside. That is, in actual fishing, the opening and closing can be performed in a state where the bait fish is placed inside.

< clamping piece >

Fig. 4 to 7 are sectional views IV-IV, V-V, VI-VI, and VII-VII of fig. 1, respectively, in fig. 1. In these figures, the right-left direction on the paper surface is the right-left direction 49 of the bait holder 10. That is, the left and right directions mean the left and right directions of the bait holder 10 viewed from the rear, respectively.

As shown in fig. 1 and 2, the holding piece 15 is bent in a C-shape as a whole. Specifically, the clamping piece 15 includes: a front leg 32; a rear leg 33; an abutting portion 34 formed to span between the front leg 32 and the rear leg 33; a first projection 35 and a second projection 36 (corresponding to "connecting projections" described in the claims) provided to the front leg 32; and a third projection 37 (corresponding to the "connecting projection" described in the claims) provided to the rear leg 33.

As shown in fig. 1, the first projection 35 and the second projection 36 are integrally formed. The two are arranged to face each other in the axial direction 22, and are engaged with the shaft portion 18 by a structure described later. The distance separating the first projection 35 and the second projection 36 is not particularly limited, and is appropriately set in the range of 5mm to 20 mm. The third projection 37 is opposed to the second projection 36, and is disposed rearward in the axial direction 22 with respect to the second projection 36. The third projection 37 is engaged with the shaft 18 by a structure described later. The distance between the second projection 36 and the third projection 37 is also not particularly limited, and is appropriately set in the range of 5mm to 20 mm.

As shown in fig. 4, the first protrusion 35 is formed in a block shape. However, the outer shape of the first projection 35 is not particularly limited, and as shown in the figure, it may be a size that allows the shaft portion 18 to be fitted. A groove 38 is provided in the first projection 35. The groove 38 is formed by forming an opening 40 in the lower surface of the first projection 35 and extending upward continuously from the opening 40. The width dimension of the groove 38 corresponds to the outer diameter of the shaft portion 18. The length dimension (length in the vertical direction 24) of the groove 38 is not particularly limited, and is set to be at least larger than the outer diameter of the shaft portion 18. In the present embodiment, a seat portion 41 is formed at the peripheral edge portion of the opening 40. The seat 41 enlarges the inner diameter of the opening 40. Of course, the seat 41 may be omitted.

In the present embodiment, the second projection 36 has the same outer shape as the first projection 35, and the lower surface of the second projection 36 is provided with a groove similar to the groove 38. Of course, the shape of the second protrusion 36 may be different from the shape of the first protrusion 35. The first projection 35 and the second projection 36 are connected by a connecting rod 42 and are integrally formed.

As shown in fig. 1, 2 and 4, the front leg 32 is continuous with the front end of the first projection 35. The front leg 32 is curved in an arc shape so as to bulge outward in the left direction from the first projection 35 and extends upward.

As shown in fig. 5, the third projection 37 is also formed in a block shape. The outer shape of the third projection 37 is not particularly limited, and may be a size that allows the shaft portion 18 to be fitted therein, as shown in the drawing. In the present embodiment, the rib 43 is formed on the lower surface of the third projection 37, but the rib 43 may be omitted. A groove 44 is provided in the third projection 37. The groove 44 is formed by forming an opening 45 in the upper surface of the third projection 37 and extending downward continuously from the opening 45. The inner wall surface of the groove 44 is formed in an arc shape corresponding to the outer diameter of the shaft portion 18. A seat portion 46 is formed at the peripheral edge portion of the opening 45. The inner diameter of the opening 45 is enlarged by the seat 46. Of course, the seat 46 may be omitted.

As shown in fig. 1, 2 and 5, the rear leg 33 is continuous with the rear end of the third projection 37. Similarly to the front leg 32, the rear leg 33 is curved in an arc shape so as to bulge outward in the left direction from the third projection 37 and extends upward.

As shown in fig. 1, 2, 6, and 7, the contact portion 34 is formed in an elongated bar shape, extends in the axial direction 22, and is curved so as to be slightly convex upward. The abutting portion 34 is smoothly continuous with the upper end of the front leg 32 and the upper end of the rear leg 33, and is disposed so as to be bridged therebetween. As shown in fig. 6 and 7, the contact portion 34 has a rectangular cross-sectional shape, and ensures a predetermined bending rigidity. Of course, the cross-sectional shape of the contact portion 34 is not particularly limited, and may be any shape that can ensure the predetermined bending rigidity.

Since the abutting portion 34 extends in the axial direction 22 continuously from the upper end of the front leg 32 and the upper end of the rear leg 33, when the holding posture of the holding

pieces

15 and 16 is changed (see fig. 2), the abutting portion 34 abuts along the body side portion, particularly along the body side back portion, of the bait fish placed on the shaft portion 18.

As shown in fig. 1 to 3, the clamping piece 16 is also bent into a C-shape as a whole, similarly to the clamping piece 15. Specifically, the clamping piece 16 includes: a front leg 52; the rear leg 53; an abutting portion 54 formed to span between the front leg 52 and the rear leg 53; a first projection 55 (corresponding to the "connecting projection" in the embodiment) provided on the front leg 52; and a second projection 56 (corresponding to the "coupling projection" described in the claims) provided to the rear leg 53.

As shown in fig. 1, the first projection 55 and the second projection 56 are disposed to face each other in the axial direction 22, and engage with the shaft portion 18. The distance separating the first projection 35 and the second projection 36 is not particularly limited. In the present embodiment, the first projection 55 is disposed between the first projection 35 and the second projection 36 provided on the holding piece 15, and the second projection 56 is disposed in front of the third projection 37 provided on the holding piece 15. However, the positions of the first projection 55 and the second projection 56 are also not particularly limited.

As shown in fig. 6, the first projection 55 is formed in a key-shaped block shape. Of course, the outer shape of the first projection 55 is not particularly limited, and may be a size that allows the shaft portion 18 to be fitted therein, as shown in the drawing. A groove 58 is provided in the first projection 55. The groove 58 is formed by forming an opening 60 in the right surface of the first projection 55 and extending continuously from the opening 60 in the left direction. The width of the groove 58 corresponds to the outer diameter of the shaft 18, and the inner wall surface of the groove 58 is formed in an arc shape. A seat portion 61 is formed at a peripheral edge portion of the opening 60. The inner diameter of the opening 60 is enlarged by the seat portion 61. Of course, the seat 61 may be omitted.

As shown in fig. 1 and 2 and fig. 4 and 6, the front leg 52 is continuous with the front end of the first projection 55. As shown in fig. 4, the front leg 52 protrudes outward in the right direction from the first projection 55 (see fig. 6), is curved in an arc shape so as to bulge in this direction, and extends upward (see fig. 4). The front leg 52 may have a shape symmetrical to the front leg 32 of the holding piece 15.

As shown in fig. 7, the second protrusion 56 is also formed in a block shape. The external shape of the second projection 56 is not particularly limited, and may be a size that allows the shaft portion 18 to be fitted therein, as shown in the drawing. A groove 63 is provided in the second projection 56. The groove 63 is formed by forming an opening 65 in the upper surface of the second projection 56 and extending downward continuously from the opening 65. The inner wall surface of the groove 63 is formed in an arc shape corresponding to the outer diameter of the shaft portion 18, similarly to the groove 58 (see fig. 6). A seat portion 66 is formed at a peripheral edge portion of the opening 65. The inner diameter of the opening 65 is enlarged by the seat 66. Of course, the seat 66 may be omitted.

As shown in fig. 1 and 2 and fig. 5 and 7, the rear leg 53 is continuous with the rear end of the second projection 56. The rear leg 53 protrudes outward in the right direction from the second projection 56 (see fig. 7), is curved in an arc shape so as to bulge in this direction, and extends upward. The rear leg 53 may have a shape symmetrical with the rear leg 33 of the holding piece 15.

As shown in fig. 1, 2, 6, and 7, the contact portion 54 has the same outer shape as the contact portion 34 of the holding piece 15, and is formed in an elongated bar shape. That is, the contact portion 54 extends in the axial direction 22 and is curved so as to be slightly convex upward. The abutting portion 54 is smoothly continuous with the upper end of the front leg 52 and the upper end of the rear leg 53, and is disposed so as to be bridged therebetween. As shown in fig. 6 and 7, the abutting portion 54 has a quadrangular cross-sectional shape. In the present embodiment, the cross-sectional shape of the abutting portion 54 and the cross-sectional shape of the abutting portion 34 are different, but the cross-sectional shapes may be the same. In short, the contact portion 54 may also ensure the bending rigidity equivalent to that of the contact portion 34.

Since the abutting portion 54 extends in the axial direction 22 continuously from the upper end of the front leg 52 and the upper end of the rear leg 53, when the holding posture of the holding

pieces

15 and 16 is changed (see fig. 2), the abutting portion 54 abuts along the body side portion, particularly along the body side back portion, of the bait fish placed on the shaft portion 18. That is, the abutting portions 54 and the abutting portions 34 abut against the back of the bait fish on the body side from the left and right sides, and sandwich the bait fish.

In the present embodiment, as described above, the clamping

pieces

15 and 16 are C-shaped. That is, a window 51 having a large opening is formed in the center of the clamping

pieces

15 and 16. The abutting

portions

34, 54 form the edges of the window 51. The operation and effect of the window 51 will be described later.

< posture holding mechanism >

As shown in fig. 2 and 3 and fig. 1, the posture holding mechanism 31 is disposed between the holding piece 15 and the holding piece 16, and in the present embodiment, a ratchet mechanism is used. Specifically, the posture holding mechanism 31 includes a slider 68 and a slide base 69. The slide base 69 is formed integrally with the contact portion 34 of the clamping piece 15, and the slider 68 is formed integrally with the contact portion 54 of the clamping piece 16. Of course, the slide base 69 and the slider 68 may be constituted by a member different from the holding

pieces

15, 16, and fixed to the holding

pieces

15, 16 by a known mechanism.

The slider 68 is provided so as to protrude from the contact portion 54, and has a rectangular flat plate-like cross-sectional shape as shown in fig. 2. When the holding piece 16 is in the holding posture, the slider 68 protrudes toward the holding piece 15 side. The slide base 69 is provided on the contact portion 34 and is formed in a shape engageable with the slider 68. As shown in fig. 3, the slider 68 is formed with teeth 67, and a click (not shown) is formed on an inner wall surface of the slide base 69. When the slider 68 is inserted into the slide base 69, the teeth 67 engage with the pawls of the slide base 69 to maintain the holding posture. In the present embodiment, since the holding

pieces

15 and 16 are made of resin or rubber, when the angler presses the holding piece 16 downward from above, the holding piece 16 is easily elastically deformed, and the teeth 67 are disengaged from the ratchet.

In the present embodiment, the above-described ratchet mechanism is employed as the posture holding mechanism 31, but other mechanisms may be employed. The posture holding mechanism 31 may be omitted. In this case, for example, the holding

pieces

15 and 16 may be bound by a rubber band or other rubber belt to hold both in the holding posture. Instead of the rubber band, a string or a hook and loop fastener may be used, and both the holding

pieces

15 and 16 may be held in the holding posture by being held by a clip.

The pair of holding

pieces

15 and 16 are attached to the hook 12 by the following structure.

As shown in fig. 1, 4, and 5, the clamping piece 15 is attached to the shaft portion 18 by fitting the shaft portion 18 with the first projection 35, the second projection 36, and the third projection 37. As shown in fig. 4, the shaft portion 18 relatively moves in the radial direction to fit into the grooves 38 provided in the first projection 35 and the second projection 36 in the up-down direction. As described above, the outer diameter of the shaft portion 18 corresponds to the width of the groove 38, and specifically, a tolerance between the outer diameter and the width is preferably set so that the shaft portion 18 is press-fitted into the groove 38. As shown in fig. 5, the third projection 37 is fitted to the shaft portion 18 from below upward relative to the shaft portion 18. The relationship between the outer diameter of the shaft portion 18 and the width of the groove 44 is preferably set to a tolerance such that the shaft portion 18 is press-fitted into the groove 44.

The first projection 35, the second projection 36, and the third projection 37 are fitted to the shaft 18, and the projections 35 to 37 can rotate with the shaft 18 as a rotation reference. However, in the present embodiment, since the base portion 29 of the fixing pin 14 is disposed on the shaft portion 18, the base portion 29 and the shaft portion 18 are inserted into the groove 38 in a state of being overlapped vertically. That is, the first projection 35 and the second projection 36 are structurally restricted from rotating relative to the shaft portion 18, so that the first projection 35 and the second projection 36 are more reliably fixed to the shaft portion 18. Further, the first projection 35 and the second projection 36 are more firmly fixed to the shaft portion 18 by using an adhesive or the like, for example.

As shown in fig. 1, 6, and 7, the clamping piece 16 is attached to the shaft portion 18 by fitting the first projection 55 and the second projection 56 to the shaft portion 18. As shown in fig. 6, the shaft portion 18 relatively moves in the radial direction to fit into the groove 58 provided in the first projection 55 in the left-right direction 49. As described above, the outer diameter of the shaft portion 18 corresponds to the width of the groove 58, and specifically, it is preferable to set a tolerance between the outer diameter and the width of the groove 58 so that the shaft portion 18 is press-fitted into the groove. As shown in fig. 7, the second projection 56 is fitted to the shaft portion 18 from below upward relative to the shaft portion 18. The relationship between the outer diameter of the shaft portion 18 and the width of the groove 63 is preferably set to a tolerance such that the shaft portion 18 is press-fitted into the groove 63.

The first projection 55 and the second projection 56 are fitted to the shaft portion 18, and these two projections can be rotated with the shaft portion 18 as a rotation reference. In the present embodiment, since the gripping piece 15 is fixed to the shaft portion 18 as described above, the gripping piece 16 rotates and changes its posture with respect to the gripping piece 15 fixed to the shaft portion 18 in an upright posture as shown in fig. 2 and 3. That is, the clamping piece 16 is displaced between a holding posture (see fig. 2) in which the contact portion 54 is close to the contact portion 34 of the clamping piece 15 and an open posture (see fig. 3) in which the contact portion 54 is away from the contact portion 34. Of course, when the fixing needle 14 is omitted and the gripping piece 15 is also rotatable with respect to the shaft portion 18 as described above, the gripping piece 15 and the gripping piece 16 relatively approach or separate from each other, and the posture changes between the holding posture and the open posture.

Use key of bait holder

As described above, the bait holder 10 is attached to a fishhook assembly for fishing a hairtail, for example, and is used as a "hairtail heaya". The angler loads and unloads the bait fish to and from the bait holder 10 as follows.

As shown in fig. 2 and 3, the angler holds the bait holder 10 by hand and rotates the grip piece 16. Since the gripping piece 15 is fixed to the shaft portion 18, the gripping piece 16 is opened with respect to the gripping piece 15. At this time, when the slider 68 of the posture holding mechanism 31 is engaged with the slide base 69, the angler can easily release the engagement of the slider 68 and the slide base by pressing the slider downward. Accordingly, the pair of holding

pieces

15 and 16 are changed from the holding posture shown in fig. 2 to the open posture shown in fig. 3.

The bait fish is disposed on the shaft portion 18. At this time, the bait fish is inserted into the fixing needles 13 and 14 and is stably arranged along the shaft 18. Since the fixing needle 14 is disposed in front of the shaft portion 18 and in the vicinity of the plummet 11, the fixing needle 14 penetrates into a hard portion around the head of the bait fish. Therefore, even in the case of using fish such as frozen sardine, which is easily deformed, as the bait fish, the bait fish can be kept stable on the shaft portion 18. When the angler manipulates the grip pieces 16 to change the

grip pieces

15 and 16 to the holding posture, the bait fish pierced by the fixing needles 13 and 14 is wrapped inside the

grip pieces

15 and 16.

The holding

pieces

15 and 16 are not made of metal wire as in the prior art, but are made of the above-mentioned resin or the like and have a predetermined rigidity, and therefore, are not easily deformed even when the hook unit is vigorously handled in water, and can prevent the bait fish from falling off the bait holder 10 during actual fishing. Further, since the clamping

pieces

15 and 16 are made of the resin, the fishing line is not easily entangled. Therefore, even when the bait holder 10 is used for a fishing hook assembly for boat fishing, it is possible to prevent fishing lines from being entangled with each other in actual fishing. When the holding

pieces

15 and 16 are made of resin, the resin may have a light accumulating function or a color changing function.

On the other hand, the angler can quickly and easily replace the bait fish placed on the shaft 18 by operating the gripping piece 16 to displace the

gripping pieces

15 and 16 to the open posture (see fig. 3). In the present embodiment, the above-described posture change can be easily performed only by operating the grip piece 16, and therefore, there is an advantage that the bait fish can be quickly attached and detached in actual fishing.

In the present embodiment, since the posture holding mechanism 31 is provided, when the holding

pieces

15 and 16 are displaced to the holding posture, the posture can be held. Therefore, even if the hook assembly is violently operated during actual fishing, the angler does not inadvertently displace the holding

pieces

15 and 16 to the open position, and the bait fish can be reliably prevented from dropping.

Since the posture holding mechanism 31 is a ratchet mechanism, the posture holding of the holding

pieces

15 and 16 can be easily and reliably performed, and the posture holding can be easily released. In addition, the following advantages are also provided: the ratchet mechanism having a simple structure can be easily and inexpensively manufactured integrally with the holding

pieces

15, 16 by molding using a mold, for example.

As shown in fig. 1 to 3, the holding

pieces

15 and 16 have windows 51. Therefore, when the holding

pieces

15 and 16 are displaced to the holding posture, the body-side central portion of the bait fish disposed on the shaft portion 18 is largely exposed, and the presence of the bait can be strongly shown to the target fish.

In the present embodiment, the abutting

portions

34, 54 abut along the body-side back of the bait fish in a state where the holding

pieces

15, 16 are in the holding posture and wrap the bait fish. That is, the abutting

portions

34, 54 press the body side portions of the bait fish from the left-right direction 49, and therefore, the bait fish is stabilized. Further, as described above, since the abutting

portions

34, 54 divide a part of the window 51, the size of the window 51 becomes sufficiently large. Therefore, there is an advantage that the body side of the bait fish is more exposed.

As shown in fig. 1, in the present embodiment, since the clamping

pieces

15 and 16 are rotatably connected to the shaft portion 18 via the first to third protrusions 35 to 37 and the first and

second protrusions

55 and 56, the clamping

pieces

15 and 16 can be smoothly rotated to change the posture. The projections 35 to 37, 55, 56 have

grooves

38, 44, 58, 63 opening on the peripheral surfaces of the projections 35 to 37, 55, 56, and the shaft 18 can be easily fitted into the

grooves

38, 44, 58, 63. Therefore, the work of attaching and detaching the shaft portions 18 to and from the clamping

pieces

15 and 16 is simplified.

< modification example >

The bait holder 70 according to the modification differs from the bait holder 10 according to the embodiment in that: the first projection 75, the second projection 76, and the third projection 77 of the clamping piece 15 (corresponding to the "connecting projection" in the present embodiment) and the first projection 85 and the second projection 86 of the clamping piece 16 (corresponding to the "connecting projection" in the present embodiment) according to the present modification are different in configuration from the first projection 35, the second projection 36, and the third projection 37, and the first projection 55 and the second projection 56 of the clamping piece 16 according to the above embodiment; the lead weight 11 is attached with a pattern 72 showing the head of a fish, and is provided with an anchor 71(anchor) for supporting a bait fish. The other structure is the same as that of the bait holder 10 according to the above embodiment.

The pattern 72 is simply attached by cutting the surface of the lead sinker 11. By attaching such a pattern 72, the bait holder 70 functions as a lure. In the present modification, the weight 11 is marked with a mark "50", and the weight has a size of 50.

The anchor 71 is a member in which a round bar member is bent in a triangular shape, and is formed integrally with the lead weight 11. When a bait fish is placed on the shaft portion 18, the anchor 71 is pressed into the head of the bait fish. Accordingly, the bait fish is more stably arranged on the shaft portion 18.

Fig. 9 to 13 are a sectional view IX to IX of fig. 8, a sectional view X to X of fig. 8, a sectional view XI to XI of fig. 8, a sectional view XII to XII of fig. 8, and a sectional view XIII to XIII of fig. 8, respectively.

As shown in fig. 9, a groove 78 is provided in the first projection 75. The groove 78 is formed by forming an opening 40 in the upper surface of the first projection 75 and extending continuously and downward from the opening 40. The width dimension of the groove 78 corresponds to the outer diameter of the shaft portion 18. The length dimension (length in the vertical direction 24) of the groove 78 is the same as that of the groove 38 according to the above embodiment. In this modification, a seat portion 41 is also formed at the peripheral edge portion of the opening 40. The inner diameter of the opening 40 is enlarged by the seat portion 41. Of course, the seat 41 may be omitted.

As shown in fig. 10, the second projection 76 is formed in a block shape. The external shape of the second projection 76 is not particularly limited, and may be a size that allows the shaft portion 18 to be fitted therein, as shown in the drawing. A groove 84 is provided in the second projection 76. The groove 84 is formed by forming an opening 45 in the upper surface of the second projection 76 and extending downward continuously from the opening 45. The inner wall surface of the groove 84 is formed in an arc shape corresponding to the outer diameter of the shaft portion 18. A seat portion 46 is formed at the peripheral edge portion of the opening 45. The inner diameter of the opening 45 is enlarged by the seat 46. Of course, the seat 46 may be omitted.

As shown in fig. 11, the third projection 77 is also formed in a block shape. A long hole 73 is formed in the third projection 77. In the same figure, the long hole 73 extends in the direction perpendicular to the paper surface, i.e., the axial direction 22, and penetrates the third projection 77. The maximum inner diameter of the elongated hole 73 corresponds to the outer diameter of the shaft portion 18 so that the shaft portion 18 fits into the elongated hole 73. As shown in the figure, the inner wall surface of the elongated hole 73 has a wedge shape extending in the vertical direction 24. However, the shape of the inner wall surface of the elongated hole 73 is not particularly limited, and in any case, the shaft portion 18 may be formed so as to be fittable. The dimension of the elongated hole 73 in the vertical direction 24 ensures a sufficient dimension required for the hook-tip curved portion 20 of the hook portion 12 to be inserted through in the longitudinal direction.

As shown in fig. 12, the first projection 85 is formed in a key-shaped block shape. Of course, the outer shape of the first projection 85 is not particularly limited, and may be a size that allows the shaft portion 18 to be fitted therein, as shown in the drawing. A groove 88 is provided in the first projection 85. The groove 88 is formed by forming an opening 60 in the right surface of the first projection 85 and extending continuously from the opening 60 in the left direction. The width of the groove 88 corresponds to the outer diameter of the shaft 18, and the inner wall surface of the groove 88 is formed in an arc shape. A seat portion 61 is formed at a peripheral edge portion of the opening 60. The inner diameter of the opening 60 is enlarged by the seat portion 61. Of course, the seat 61 may be omitted.

As shown in fig. 13, the second projection 86 is also formed in a block shape. The second projection 86 has a long hole 74 formed therein. The elongated hole 74 has the same shape as the elongated hole 73 formed in the third projection 77 (see fig. 11), and extends in the direction perpendicular to the paper surface, i.e., the axial direction 22 in fig. 13, and penetrates through the second projection 86. The maximum inner diameter of the elongated hole 74 corresponds to the outer diameter of the shaft portion 18 so that the shaft portion 18 fits into the elongated hole 74. As shown in the figure, the inner wall surface of the long hole 74 has a wedge shape extending in the vertical direction 24. The dimension of the elongated hole 74 in the vertical direction 24 is set to a dimension in which the hook tip bending portion 20 can be inserted.

In the present modification, when the clamping

pieces

15 and 16 are attached to the shaft portion 18, the hook portion 12 is inserted into the

elongated holes

73 and 74 provided in the third projection 77 and the second projection 86. Specifically, the hook-point bending portion 20, the hook shank 19, and the shaft portion 18 are sequentially inserted through the

elongated holes

73, 74 in the longitudinal direction, and then the first projection 75 and the second projection 76 of the holding piece 15 are fitted into the shaft portion 18, and the first projection 85 of the holding piece 16 is fitted into the shaft portion 18. Since the

elongated holes

73, 74 extend in the vertical direction 24 as described above, the hook 12 can be smoothly inserted into the

elongated holes

73, 74 even if the barb 26 is provided in the hook-point bending portion 20. Accordingly, the third projection 77 and the second projection 86 can be reliably attached to the shaft portion 18, and the dropping of the holding

pieces

15, 16 can be reliably prevented in actual fishing.

However, in actual fishing, generally, the target bites the bait fish from below upward. In the present modification, as shown in fig. 9 and 10, the shaft portion 18 is fitted to the first projection 75 and the second projection 76 from above in the vertical direction 24, and therefore, even when a target bites a bait fish, the grip piece 15 can be prevented from falling off from the hook portion 12 due to collision.

< cage unit >

The holder unit 90 is implemented as a modification of the bait holder 10 according to the above-described embodiment, and the pair of clamping

pieces

15 and 16 are connected to each other so as to be rotatable relative to each other via a connecting shaft 91.

As shown in the figure, the first projection 35 is provided with a through hole 93 along the axial direction 22 (direction perpendicular to the paper surface). Although not shown in the same drawing, similar through holes 93 are also provided in the second projection 36, the third projection 37, and the first projection 55 and the second projection 56. The coupling shaft 91 is inserted into the through holes 93, and the clamping

pieces

15 and 16 are strung together by the coupling shaft 91. This enables the pair of

gripping pieces

15 and 16 to change the posture.

A groove 92 is provided in the first projection 35. The groove 92 is formed by forming an opening 94 in the lower surface of the first projection 35 and extending upward continuously from the opening 94. The width dimension of the groove 92 corresponds to the outer diameter of the shaft portion 18. The length dimension (length in the vertical direction 24) of the groove 92 is not particularly limited, and is set to be at least larger than the outer diameter of the shaft portion 18. A reduced diameter portion 95 is provided on an inner wall surface of the groove 92. The reduced diameter portion 95 may be formed of a step portion or a ridge portion formed on the inner wall surface of the groove 92. With this reduced diameter portion 95, when the shaft portion 18 is fitted into the groove 92, the shaft portion 18 is reliably fixed in the groove 92, and the holding unit 90 can be removed from the shaft portion 18. The groove 92 may be provided in the second projection 36, the third projection 37, and the first projection 55 and the second projection 56.

Since the pair of clamping

pieces

15 and 16 constitute the holder unit 90 and are detachably attached to the shaft portion 18 in this manner, if a plurality of sizes of holder units 90 are prepared in advance, the holder unit 90 corresponding to the size of the bait fish can be attached to the shaft portion 18.
