Description

Technical Field

[0001] The present invention relates to a fishing rod.

Background Art

[0002] Since fishing rods are long, there are some fishing rods with dividable blanks like those described in Patent Document 1. However, for fishing rods for large fish, even if the blanks can be divided, the grip is long and difficult to carry.

[0003] Therefore, for this type of fishing rod, there is an adopted connection structure that divides the grip into a pair of grip members, and screws a male screw protruding from the end face of one grip member into a screw hole formed in the end face of the other grip member to connect the pair of grip members to each other.

[0004] With such a connection structure, the grip members can be easily connected by screwing, and since no other members are interposed between the grip members, the hands are not caught at the connection point and it is easy to operate.

[0005] However, in the conventional connection structure, when one grip member rotates around the axis with respect to the other grip member, the screwing becomes loose. As a result, there is a risk that the connection of the grip members comes off during use, making it impossible to concentrate on fishing and being very dangerous.

Summary of the Invention

Problems to be Solved by the Invention

[0007] Therefore, the main object of the present invention is to make it difficult for the hand to get caught at the connection point and difficult for the connection of the grip member to come off while maintaining a structure in which the grip member can be easily connected by screwing.

Means for Solving the Problems

[0008] The fishing rod according to the present invention is a fishing rod provided with a grip that can be divided into a plurality of grip members, and includes a nut member that is interposed between end faces of a pair of adjacent grip members and is axially fixed so as to be rotatable around the axis with respect to one grip member, and a male screw that protrudes from an end face of the other grip member and has a thread groove formed on its side circumferential surface. The male screw is screwed into a screw hole of the nut member to further include a connection mechanism for connecting the pair of grip members to each other, and the outer peripheral surface of the nut member has a shape that does not protrude outward from the outer peripheral surfaces of the pair of grip members when the grip is viewed in the axial direction.

[0009] According to the present invention, even if the other grip member rotates around the axis with respect to one grip member, the nut member also rotates together with the other grip member, so the screwing does not loosen and it is difficult for the connection between the grip members to come off. Also, in a state where the grip members are connected to each other, the nut member does not protrude from the grip surface. Therefore, it is difficult for the hand to get caught on the nut member, making it easy to operate and difficult to get injured.

[0010] Further, the diameters of the end faces of the nut member and the pair of grip members may be the same.

[0011] According to such a configuration, the ends of both grip members and the surface of the nut member are flush, making it even more difficult to get caught.

[0012] Further, the axial length of the male screw shaft may be shorter than the axial length of the nut member.

[0013] According to such a configuration, since both grip members and the nut member are in close contact in the axial direction, no gap can be formed between the respective members, making it more difficult to get caught.

[0014] When the other grip member rotates with respect to the pair of grip members, it is difficult to operate. Therefore, a rotation restricting mechanism may be further provided which is interposed between the pair of grip members and restricts the rotation of the other grip member around the axis with respect to the one grip member.

[0015] As a specific embodiment of the rotation restricting mechanism, in a state where the male screw is screwed into the screw hole of the nut member, the rotation restricting mechanism includes an insertion hole that opens to one end surface of the end surface of the male screw portion or the one grip member, and a shaft body that protrudes from the other end surface, passes through the screw hole, and is inserted into the insertion hole. Examples include those that restrict rotation by the engagement between the insertion hole and the shaft body.

[0016] With such a configuration, the rotation restricting mechanism can be housed inside the grip, so it does not affect the operability. Also, one end side of this shaft body may be inserted and fixed to one grip member having a cylindrical shape, and the nut member may be axially fixed so as to be rotatable with respect to the shaft body. With such a configuration, in a state where both grip members are connected, the shaft body is inserted across between both grip members, so the strength of the connection portion is increased and the assembly is also simplified.

[0017] A separable fishing rod generally has blanks divided into a plurality of blank members. For this reason, considering ease of carrying and storage, when dividing the grip, it is preferably divided as much as possible in accordance with the length of the blank member.

[0018] Here, for fishing rods for large fish such as tuna and swordfish, a foregrip portion is provided on the tip side of the reel seat to which the reel is attached, and a rear grip portion is provided on the hand side. When a fish bites, the rear grip portion is inserted into a belt or the like wound around the waist, and the foregrip portion is grasped with both hands and pulled up. Therefore, it is preferable to divide the rod at the rear grip portion where it is difficult to apply a large force compared to the foregrip portion.

[0019] If we do so, for example, when dividing the grip into a hand-side grip including the grip end and a tip-side grip member on the tip side of the rod further from the hand-side grip, inevitably the tip-side grip member including the reel seat and the foregrip portion becomes longer than the hand-side grip member. For this reason, it is inevitable that the length of the tip-side grip member is made to match the length of the blanks member, and the remaining portion is made into the hand-side grip member.

[0020] However, since connection parts of the grip end and the like are built into the grip end side, if the hand-side grip member becomes too short, there will be a problem that the connection mechanism and the rotation restricting mechanism interfere with the parts built into the grip end side.

[0021] Therefore, either one of the pair of grip members may include the grip end, the insertion hole may be provided in the grip member including the grip end, and the shaft body may be provided in the grip member adjacent to the grip member including the grip end.

[0022] With such a configuration, when matching the length of the grip member adjacent to the grip member including the grip end to the length of the blanks member, it suffices to match it including the shaft body, so the length of the grip member including the grip end can be set longer by the length of the shaft body. As a result, it becomes difficult for the connection mechanism and the rotation restricting mechanism to interfere with the parts built into the grip end side.

[0023] The fishing rod according to the present invention is a fishing rod provided with a grip that can be divided into a plurality of grip members, and among a pair of adjacent grip members, a screw hole that opens in the end face of one grip member and a male screw that protrudes from the end face of the other grip member and has a screw groove formed on its side circumferential surface are provided. By screwing the male screw into the screw hole, a connection mechanism for connecting the pair of grip members and a nut member that screws onto the male screw are provided, and the outer peripheral surface of the nut member is shaped so as not to protrude outward from the outer peripheral surfaces of the pair of grip members when the grip is viewed in the axial direction.

[0024] Also according to the present invention, by rotating the nut member in a direction opposite to the tightening direction with the male screw screwed into the screw hole, the rotation of one grip member around the axis with respect to the other grip member is restricted, and the connection of the grip members becomes difficult to come off. Furthermore, with the grip members connected to each other, the nut does not protrude from the grip surface, so it is difficult for the hand to get caught, it can be operated smoothly, and it is difficult to get injured.

Effects of the Invention

[0025] Thus, in the fishing rod according to the present invention, while maintaining a structure in which the grip members can be easily connected by screwing, it is difficult for the hand to get caught at the connection point, and the connection of the grip members can be made difficult to come off.

Modes for Carrying Out the Invention

[0027] A fishing rod according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

[0028] <First Embodiment> The fishing rod 100 of this embodiment is mainly used when fishing for large fish. As shown in FIG. 1, a blank 10 is provided on the tip side, and a grip 20 is provided on the hand side, and it is configured to be divisible into a plurality of parts.

[0029] The blank 10 constitutes the rod tip and is a portion that greatly deflects when a fish bites. In this embodiment, the blank 10 is configured to be separable from the grip 20, and the blank 10 itself is also configured to be divisible into three blank members 11. Note that the blank 10 itself does not necessarily have to be divisible. The number of divisions is not limited to three and may be two or more. A plurality of line guides (not shown) are installed on the blank 10 at substantially equal intervals.

[0030] The grip 20 is a portion other than the blank 10 and is mainly the portion held by the hand. The grip 20 of this embodiment is configured to be divisible into a tip-side grip member 21 (one grip member) that constitutes the tip side (rod tip side) of the grip 20 and a hand-side grip member 22 (the other grip member) that constitutes the hand side (grip end 20e side) of the grip 20. Note that the grip 20 is not limited to being divisible into two parts and may be configured to be divisible into three or more parts.

[0031] More specifically, the grip 20 of the present embodiment includes a reel sheet 20a for mounting a reel, a foregrip portion 20b provided on the tip side of the reel sheet 20a, and a rear grip portion 20c provided on the hand side of the reel sheet 20a. The rear grip portion 20c is divided into two at an intermediate position on the tip side of the grip end member 20e. That is, the grip 20 is divided at a position between the reel sheet 20a and the grip end member 20e. Therefore, the tip-side grip member 21 constitutes the reel sheet 20a, the foregrip portion 20b, and a part of the rear grip portion 20c. The hand-side grip member 22 constitutes a part of the rear grip portion 20c including the grip end. The hand-side end portion of the tip-side grip member 21 has a cylindrical shape, and the tip-side end portion of the hand-side grip member 22 also has a cylindrical shape.

[0032] Thus, in the present embodiment, a connection mechanism 30 is further provided between the tip-side grip member 21 and the hand-side grip member 22. This connection mechanism 30 includes a nut member 31 that is interposed between the two grip members 21 and 22 and is axially fixed so as to freely rotate around the axis with respect to the tip-side grip member 21, and a male screw 32 that protrudes from the end face of the hand-side grip member 22 and has a screw hole of the nut member 31 formed on its side circumferential surface.

[0033] The nut member 31 of the present embodiment is rotatably axially fixed to the tip-side grip member 21 via a shaft body 33 that is inserted and fixed into the cylindrical tip-side grip member 21. More specifically, the shaft body 33 is provided with a hook portion 33a on its side circumferential surface, and the nut member 31 through which the shaft body 33 passes is hooked on this hook portion 33a so as not to come off. The shaft body 33 extends so as to protrude from the nut member 31 in the direction opposite to the insertion direction with respect to the tip-side grip member 21. The nut member 31 is provided with a flange 31a that protrudes radially inward from its inner circumferential surface, and in a state where this flange 31a is hooked on the hook portion 33a, it is axially fixed to the end face of the tip-side grip member 21 without a gap.

[0034] Further, when viewed from the axial direction of the grip 20, the nut member 31 is formed in a shape such that its outer peripheral surface does not project radially outward beyond the outer peripheral surfaces of both grip members 21 and 22. Note that the nut member 31 of the present embodiment is annular, and its diameter is the same as the diameters of the end faces 21s and 22s of both grip members 21 and 22. The diameter of the nut member 31 does not have to be the same as the diameters of the end faces 21s and 22s of both grip members 21 and 22, and may be a length equal to or less than that diameter.

[0035] The length of the male screw 32 in its protruding direction (axial direction) is shorter than the length of the nut member 31 in the rotational axis direction.

[0036] The connection mechanism 30 of the present embodiment further includes an annular elastic body 34 that is interposed between the nut member 31 and the male screw 32 and that, with the male screw 32 screwed into the screw hole of the nut member 31, pushes back the proximal grip member 21 in a direction away from the nut member 31.

[0037] In addition, the grip 20 of the present embodiment further includes a rotation restricting mechanism 40 that restricts rotation of the proximal grip member 22 around the axis with respect to the distal grip member 21.

[0038] As shown in FIG. 2, this rotation restricting mechanism 40 includes an insertion hole 41 that opens to the end face of the male screw 32 and an extension portion 42 that protrudes from the nut member 31 of the shaft body 33 and is inserted into the insertion hole 41. The rotation is restricted by engaging the insertion hole 41 and the extension portion 42 of the shaft body 33. The extension portion 42 of the shaft body 33 corresponds to the shaft body in claim 5. Specifically, the rotation is restricted by the engagement structure between the shaft body 33 and the insertion hole 41. The engagement structure of the present embodiment includes an engagement groove 43 formed on the other end face of the shaft body 33 and an engagement convex portion 44 formed on the bottom surface of the insertion hole 41, and these are engaged with each other. However, for example, the cross-sectional shapes of the insertion hole 41 and the shaft body 33 may be configured to be engaged with each other as shapes other than circular (specifically, square shape, triangular shape).

[0039] Next, a method of assembling the grip 20 according to the present embodiment will be described with reference to FIGS. 2 and 3.

[0040] First, insert the extension portion 42 of the shaft body 33 protruding from the tip-side grip member 21 into the insertion hole 41 of the hand-side grip member 22. Then, insert the male screw 32 into the screw hole of the nut member 31 axially fixed to the shaft body 33, and rotate the nut member 31 around the axis. When starting to rotate the nut member 31, the extension portion 42 of the shaft body 33 moves toward the bottom side of the insertion hole 41, and the engaging groove 43 and the engaging convex portion 44 start to engage with each other. When further rotating the nut member 31, the engaging groove 43 and the engaged portion 44 are completely engaged, the tip surface of the male screw 32 presses the elastic body 34, and the entire hand-side grip member 22 is pushed back in a direction away from the nut member 31 by the restoring force of the elastic body 34, suppressing the looseness due to screwing.

[0041] According to the fishing rod 100 according to the present embodiment, since the hand-side grip member 22 does not rotate around the axis with respect to the tip-side grip member 21, the screwing is not loosened, the connection between the grip members 21 and 22 is difficult to come off, and it is easy to operate. Also, in the state where the grip members 21 and 22 are connected, the nut member 31 does not protrude from the surface of the grip 20. Therefore, it is difficult for the hand to get caught on the nut member 31, so it is easy to operate and difficult to get injured.

[0042] Also, in the present embodiment, since the tip-side grip member 21 is formed in a cylindrical shape and the nut member 31 is axially fixed so as to be rotatable around the axis via the shaft body 33 inserted and fixed to the tip-side grip member 21, the assembly becomes easy. Further, since the rotation restricting mechanism 40 is constituted by the extension portion 42 of the shaft body 33 and the insertion hole 41 formed in the other grip member 22, the number of parts can be reduced and the manufacturing cost can be suppressed. Further, since the shaft body 33 is inserted so as to straddle between the two grip members 21 and 22, the strength of the connection portion is also improved.

[0043] <Second Embodiment> The fishing rod 100 according to the present embodiment is another embodiment of the connection mechanism and the rotation restricting mechanism. In FIG. 4, the same parts as those in the first embodiment are denoted by the same reference numerals.

[0044] The connection mechanism 50 of this embodiment includes a screw hole 51 that opens to the end face 22s of the hand-side grip member 22, and a male screw 52 that protrudes from the end face 21s of the tip-side grip member 21 and has a screw groove formed on its side peripheral surface that engages with the screw hole 51. In this embodiment, the tip-side grip member 21 is cylindrical, a shaft body 53 is inserted and fixed thereto, and the portion of the shaft body 53 that protrudes from the tip-side grip member 22 is used as the male screw 52.

[0045] Also, the rotation restricting mechanism 60 of this embodiment is a nut member that is screwed onto the male screw 52. This nut member 60 is formed in a shape such that, when viewed in the axial direction of the grip 20, its outer peripheral surface does not protrude radially outward beyond the outer peripheral surfaces of both grip members 21 and 22. Note that the diameter of the nut member 60 of this embodiment is the same as the diameters of the end faces 21s and 22s of both grip members 21 and 22. The diameter of the nut member 60 does not have to be the same as the diameters of the end faces 21s and 22s of both grip members 21 and 22, and it may have a length equal to or less than that diameter. The rotation restricting mechanism 60 of this embodiment restricts the rotation of the hand-side grip member 22 relative to the tip-side grip member 21 by screwing the male screw 52 into the screw hole 51, bringing the hand-side grip member 22 into close contact with the nut member 60, and then rotating the nut member 60 in the direction opposite to the tightening direction.

[0046] Note that the connection mechanism 50 is configured such that the male screw 52 can be screwed to the bottom of the screw hole 51 so that the nut member 60 is in close contact with the end face 22s of the hand-side grip member 22 in a state where the nut member 60 is screwed onto the male screw 52 to a position where it is in close contact with the end face 21s of the tip-side grip member 21. Thereby, each member is in close contact without any gaps.

[0047] <Other Embodiments> Note that the present invention is not limited to the above-described embodiment. In each of the above embodiments, the grip is divided in the middle of the rear grip portion, but for example, it may be divided in the middle of the front grip portion.

[0048] In addition, combinations or modifications of parts of various embodiments may be made as long as they do not go against the spirit of the present invention.
