Abstract
Description
[Technical Field]
[0001] The present invention relates to a rod holder that is attached to a rod holder. [Background technology]
[0002] A rod holder is used as a stand for a fishing rod to stop the rod from moving unnecessarily when fishing for crucian carp, etc. It is usually forked and is attached to the end of a rod holder that is about the same length as the fishing rod.
[0003] Generally, rod holders come in a variety of shapes and sizes depending on the shape of the fishing rod and the user's preferences, and rod holders also come in a variety of thicknesses and lengths depending on the length of the rod used and the user's preferences, so rod holders and rod holders are available separately.
[0004] The rod holder is attached to the rod holder by inserting the male part of the rod holder into the hollow rod holder. Therefore, in order to attach the rod holder to the rod holder, the outer diameter of the male part of the rod holder needs to be the same as the inner diameter of the rod holder into which the rod holder will be inserted.
[0005] If the outer diameter of the male part of the rod holder is larger than the inner diameter of the rod holder, the rod holder cannot be inserted into the rod holder, and forcing it in could damage the rod holder. Also, if the outer diameter of the male part of the rod holder is too small compared to the inner diameter of the rod holder, the rod holder will easily come off.
[0006] Therefore, if the outer diameter of the male part of the rod holder is larger than the inner diameter of the rod holder, it is necessary to process the rod holder so that it can be inserted into the rod holder by gradually reducing the outer diameter of the male part of the rod holder or by gradually reducing the inner diameter of the rod holder.
[0007] Furthermore, if the outer diameter of the male part of the rod holder is too small compared to the inner diameter of the rod holder, it will be necessary to thicken the outer diameter of the male part of the rod holder by adding another material. Alternatively, instead of machining it to fit the actual part, there is also a method of screwing it in place (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-45942 Summary of the Invention [Problem to be solved by the invention]
[0009] However, in this way, when machining the male part of the rod holder or the inner diameter of the rod rack, or when thickening the male part of the rod holder, it is necessary to machine it in detail little by little to fit the actual item, so there was a problem that it is not something that just anyone can do, and the skills of an expert are required.
[0010] To solve the problem that the outer diameter of the male part of a rod holder does not match the inner diameter of the rod holder, making it impossible to attach the rod holder to the rod holder, and to provide a rod holder that can be easily attached to the rod holder without processing either the rod holder or the rod holder. [Means for solving the problem]
[0011] The present invention has been made to solve at least part of the above-mentioned problems, and can be realized as the following application examples. Note that the reference symbols and supplementary explanations in parentheses in this section indicate correspondence with the embodiments described below in order to aid in understanding the present invention, and do not in any way limit the present invention.
[0012] [Application example 1] The rod holder (1) described in Application Example 1 is A rod holder attached to the tip of a cylindrical rod holder for a fishing rod, a rod holder (20) for holding a fishing rod; an attachment portion (10) for attaching the rod holder (20) to the tip of the rod holder; Equipped with The mounting portion (10) is A mounting body (11) inserted from the tip of the rod holder; At least one movable part (12) that can move so as to protrude from a side surface of the mounting part main body (11); an operating unit (13) that moves the movable unit (12); a first coupling portion (14) for coupling to the rod holder (20); Equipped with The rod holder (20) is a second coupling portion (21) for coupling with the first coupling portion (14); The gist of the project is to provide the following:
[0013] In such a rod holder (1), the mounting portion (10) connected to the rod holder base (20) is inserted into the tip of a cylindrical rod holder for a fishing rod, thereby mounting the rod holder base (20) to the rod holder.
[0014] At this time, the outer diameter of the mounting body 11 is made smaller than the inner diameter of the tip of the rod holder, and the operating part 13 is operated to move the movable part 12 radially outward from the mounting body 11. This allows the outer diameter of the mounting part 10 to be made larger than the outer diameter of the mounting body 11 by the amount of movement of the movable part 12.
[0015] In this way, by operating the operating part (13) and making the outer diameter of the mounting part (10) equal to or slightly larger than the inner diameter of the tip of the rod holder, the mounting part (10) to which the rod holder stand (20) is connected can be inserted into the tip of the rod holder, and the rod holder stand (20) can be attached to the rod holder.
[0016] Therefore, by using such a rod holder (1), the rod holder (1) can be attached to the rod holder without processing either the rod holder (1) or the rod holder, regardless of the size of the inner diameter of the tip of the rod holder.
[0017] [Application example 2] The rod holder (1) according to Application Example 2 is the rod holder (1) according to Application Example 1, The operation unit (13) is a bolt (12c) attached to the movable part (12); a nut (13a) that is fitted onto the bolt (12c) and that can be rotated from outside the mounting body (11) on the axis of the bolt (12c) inside the mounting body (11) and that is restricted in position so as not to move in the axial direction of the bolt (12c) relative to the mounting body (11); The gist of the project is to provide the following:
[0018] In such a rod holder (1), in order to move the movable part (12) radially outward from the mounting body (11), a bolt (12c) is attached to the movable part (12) and a nut (13a) is used that fits onto this bolt (12c).
[0019] The nut (13a) is located inside the mounting body (11) and is rotatable from the outside, but its position is restricted so that it does not move in the axial direction of the bolt (12c) that fits into the nut (13a).
[0020] As a result, when the nut (13a) is fitted to the bolt (12c) attached to the movable part (12), the bolt (12c) moves on the axis of the nut (13a) by rotating the nut (13a), and as a result, the movable part (12) attached to the bolt (12c) moves in the radial direction of the mounting part main body (11).
[0021] Therefore, the outer diameter of the mounting part (10) can be changed with a simple structure of a bolt (12c) and a nut (13a), and the rod holder (1) can be mounted on the rod holder regardless of the inner diameter of the tip of the rod holder.
[0022] [Application example 3] The rod holder (1) according to Application Example 3 is the rod holder (1) according to Application Example 1 or Application Example 2, The gist of the present invention is that the movable portion (12) and the mounting portion main body (11) are provided with at least one annular elastic body (17) wound around their outer circumferential surfaces.
[0023] In the rod holder described in Application Example 1 or Application Example 2, the movable part (12) can tilt freely in the axial direction of the mounting part main body (11) with the point where it is attached to the bolt (12c) as a fulcrum. Therefore, when inserting the mounting part (10) into the rod holder, the tilt of the movable part (12) must be fixed by hand while inserting it into the rod holder.
[0024] Therefore, in the rod holder (1) of Application Example 3, at least one annular elastic body (17) is wound around the outer periphery of the mounting body (11) including the movable part (12).
[0025] As a result, even when the movable part (12) is moved in the radial direction of the mounting part main body (11) to a position suitable for inserting and fixing the mounting part (10) into the rod holder, the elastic force of the annular elastic body (17) allows the movable part (12) to be fixed at a certain angle relative to the axial direction of the mounting part main body (11).
[0026] This allows the movable part (12) to be easily inserted into the rod holder without having to manually fix the inclination of the movable part (12). [Brief explanation of the drawings]

[Figure 5] 1 is an external view showing the general shape of a mounting part 10 provided with anti-slip protrusions. DETAILED DESCRIPTION OF THE INVENTION
[0028] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the embodiments of the present invention are not limited to the following embodiments, and various modifications are possible as long as they fall within the technical scope of the present invention.
[0029] [First embodiment] The configuration of the rod holder 1 will be described with reference to Figures 1 and 2. Figure 1 is an external view showing the general shape of the rod holder 1 (Figure 1(A) is a front view, Figure 1(B) is a left side view, Figure 1(C) is a right side view, and Figure 1(D) is a plan view). Figure 2 is an external view showing the general shape of the mounting part with the movable part protruding (Figure 2(A) is a front view, Figure 2(B) is a right side view, and Figure 2(C) is a plan view).
[0030] As shown in FIG. 1, the rod holder 1 includes an attachment portion 10 and a rod holder base 20. As shown in FIG. 2, the mounting unit 10 includes a mounting unit main body 11, a movable unit 12, an operating unit 13, and a first connecting unit 14.
[0031] The mounting body 11 is made of aluminum alloy and has a cylindrical shape. A first notch 15 is provided on the side of the mounting body 11 to match the shape of the movable part 12, which will be described later, so that the movable part 12 can fit into the side.
[0032] In addition, second notches 16 for mounting nuts 13a (described later) are provided on both side surfaces of the mounting body 11 that sandwich the first notch 15. These second notches 16 are formed in the shape of a rectangular window with the axial direction as the longitudinal direction so that the surface of the nut 13a can be mounted in a direction perpendicular to the axial direction of the mounting body 11.
[0033] As shown in FIG. 2, the movable part 12 is made of an aluminum alloy plate material, one side of which is processed into a curved shape (outer surface 12a) with a curvature similar to that of the outer diameter of the cylindrical mounting part main body 11, and the other side is processed into a flat shape (inner surface 12b). A bolt 12c is screwed and fixed at the center of the inner surface 12b. The bolt 12c may be fixed to the inner surface 12b by welding, adhesive, or other methods.
[0034] Furthermore, two annular elastic bodies 17 are wound around the outer circumferential surfaces of both the movable part 12 and the mounting part main body 11. An O-ring is used as the annular elastic body 17, but it is not limited to an O-ring.
[0035] In addition, the part of the movable part 12 and the mounting part main body 11 where the O-ring 17 is wound has a concave groove large enough to fit the O-ring 17, and the depth of the groove is such that the O-ring 17 does not protrude from the groove.
[0036] A nut 13a that fits onto the bolt 12c is used as the operating part 13. The outer diameter of the nut 13a is approximately the same as or slightly larger than the outer diameter of the mounting part main body 11 so that the nut 13a can be easily rotated from outside the mounting part main body 11 when the nut 13a is attached to the mounting part main body 11 through the second notch 16.
[0037] Furthermore, since the outer diameter of the nut 13a is approximately the same as or slightly larger than the outer diameter of the mounting body 11, the nut 13a is restricted so that it cannot move in a direction perpendicular to the axial direction of the mounting body 11.
[0038] Therefore, when the bolt 12c is fitted into the nut 13a, by rotating the nut 13a, the bolt 12c moves in its axial direction, and the movable part 12 to which the bolt 12c is fixed moves so as to protrude from the mounting part main body 11.
[0039] The first coupling portion 14 is provided at one end of the mounting portion main body 11, and is formed in a cylindrical shape with a body diameter smaller than that of the mounting portion main body 11, and has a male thread on its outer circumferential surface.
[0040] The rod holder 20 is made of wood and is the part where the fishing rod is placed. It has a U-shape so that the fishing rod can be placed stably. It also has a second connecting part 21 for connecting with the first connecting part 14 of the mounting part 10. The second connecting part 21 has a metal female thread that fits into the male thread of the first connecting part 14.
[0041] (How to use rod holder 1) Next, a description will be given of how to use the rod holder 1. The procedure for using the rod holder 1 is as shown in the following steps (A) to (F).
[0042] (a) Insert the nut 13a into the mounting body 11 through the second notch 16 on the side of the mounting body 11, and install it so that the central axis of the nut 13a coincides with the axis of the mounting body 11. (a) The movable part 12 is inserted into the first notch 15 of the mounting part main body 11 so that the bolt 12c fits into the nut 13a that was previously attached.
[0043] (c) Rotate the nut 13a to fit the bolt 12c and the nut 13a together. (D) The mounting part 10 and the rod holder 20 are connected together using the first connecting part 14 of the mounting part 10 and the second connecting part 21 of the rod holder 20.
[0044] (O) By rotating the nut 13a, the amount of protrusion of the movable part 12 from the mounting part main body 11 is changed, and the maximum outer diameter of the mounting part 10 including the movable part 12 is adjusted so that it is equal to or slightly larger than the inner diameter of the tip of the rod holder. (f) The attachment portion 10 is inserted into the tip of a cylindrical rod holder for a fishing rod, and the rod holder 1 is attached to the rod holder to hold the fishing rod.
[0045] (Features of Rod Holder 1) In such a rod holder 1, the outer diameter of the mounting body 11 is made smaller than the inner diameter of the tip of the rod holder, and the movable part 12 can be moved by operating the operating part 13. In this way, by making the movable part 12 protrude from the side of the mounting body 11, the outer diameter of the mounting part 10 can be increased.
[0046] In this way, the maximum outer diameter of the mounting part 10 including the movable part 12 is adjusted to be equal to or slightly larger than the inner diameter of the tip of the rod holder.
[0047] As a result, by inserting the mounting part 10 to which the rod holder stand 20 is connected into the tip of the rod holder, the rod holder 1 can be easily mounted on the rod holder without any processing of the rod holder.
[0048] Furthermore, when the movable part 12 is not protruding from the mounting body 11, it is integrated with the external shape of the mounting body 11, creating a sense of unity in shape, making the rod holder 1 easy to handle.
[0049] [Second embodiment] Next, a rod holder in the second embodiment will be described with reference to Fig. 3. Fig. 3 is an external view showing the general shape of the mounting part 10 in the second embodiment when the movable part 12 is tilted.
[0050] The rod holder in the second embodiment is a modification of the first embodiment only in the method of attaching the movable part 12 and the bolt 12c, and therefore a description of the other parts will be omitted. Also, the method of using the rod holder in the second embodiment is the same as the rod holder 1 in the first embodiment, and therefore a description of the method of using the rod holder will be omitted.
[0051] In the rod holder of the second embodiment, a recess for receiving the end of the bolt 12c is provided at the center position of the inner surface 12b of the movable part 12. This allows both ends of the movable part 12 to move up and down with the end of the bolt 12c located in the recess of the inner surface 12b as a fulcrum.
[0052] (Features of the rod holder in the second embodiment) In such a rod holder, if the inside of the rod holder is tapered, after the mounting part 10 is inserted into the rod holder, the movable part 12 tilts to follow the taper inside the rod holder, so that the rod holder is mounted more firmly.
[0053] [Third embodiment] Next, a rod holder in the third embodiment will be described with reference to Fig. 4. Fig. 4 is an external view showing the general shape of the mounting part 10 in the third embodiment (Fig. 4(A) is a front view, Fig. 4(B) is a right side view, and Fig. 4(C) is a plan view).
[0054] The rod holder in the third embodiment is different from the first or second embodiment only in the number of movable parts 12, and therefore a description of the other parts will be omitted. Also, the method of using the rod holder in the third embodiment is the same as the rod holder in the first or second embodiment, and therefore a description of the method of using the rod holder will be omitted.
[0055] As shown in Figure 4, the rod holder in the third embodiment is the rod holder in the first or second embodiment, in which two movable parts 12 are provided at positions opposite each other across the central axis of the attachment body 11, and two annular elastic bodies 17 are wound around each movable part 12 so that they are both wound around the outer circumferential surface of the attachment body 11.
[0056] (Features of the rod holder in the third embodiment) In such a rod holder, the area in contact with the inner side surface of the rod holder increases as the number of movable parts 12 increases, so the rod holder can be attached to the rod holder more firmly.
[0057] [Other embodiments] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can take on various forms.
[0058] (1) In the above embodiment, a first notch 15 is provided in the mounting body 11, and the movable part 12 is fitted into the first notch 15. When the movable part 12 is not protruding from the mounting body 11, the outer surface 12a of the movable part 12 and the outer peripheral surface of the mounting body 11 are roughly aligned. However, the mounting body 11 may not be provided with the first notch 15, and only a hole for passing a bolt 12c fixed to the movable part 12 may be provided, and the movable part 12 may be overlapped with the outer peripheral surface of the mounting body.
[0059] (2) In the above embodiment, the rod holder 1 is configured by joining the mounting portion 10 and the rod holder base 20, but the mounting portion 10 and the rod holder base 20 may be formed integrally.
[0060] (3) In the above embodiment, two annular elastic bodies 17 are used for one movable part 12, but the number of annular elastic bodies 17 used for one movable part 12 may be one, or three or more annular elastic bodies 17.
[0061] (4) In the above embodiment, the shape of the mounting body 11 is cylindrical, but the mounting body 11 may be hollow, and the cross-sectional outer shape does not have to be circular, and various shapes such as square or hexagonal can be adopted.
[0062] (5) In the above embodiment, a recess is provided in the center of the inner surface 12b of the movable part 12, and the movable part 12 is placed so that the recess of the inner surface 12b is aligned with the end of the bolt 12c, so that both ends of the movable part 12 can move up and down freely with the end of the bolt 12c as a fulcrum. However, the method of attaching the movable part 12 to the end of the bolt 12c is not limited as long as both ends of the movable part 12 can move up and down freely with the end of the bolt 12c as a fulcrum.
[0063] (6) In the above embodiment, the annular elastic body 17 is used to wrap around the outer circumferential surfaces of both the movable part 12 and the mounting part main body 11, but the annular elastic body 17 may not be used.
[0064] (7) As shown in Fig. 5, in the above embodiment, in order to more firmly attach the attachment part 10 to the rod holder, an anti-slip protrusion 22 extending in the axial direction may be provided on the side of the attachment part main body 11 to prevent the attachment part 10 from slipping inside the rod holder. Fig. 5 is an external view (Fig. 5(A) is a front view, and Fig. 5(B) is a right side view) showing the general shape of the attachment part 10 provided with the anti-slip protrusion 22.
[0065] The length of the anti-slip protrusions 22 is not limited to the length from one end to the other end of the mounting body 11, but may be of various lengths. Also, the anti-slip protrusions 22 may be made of various materials such as elastic bodies, resins, metals, etc.
[0066] Furthermore, the number of anti-slip protrusions 22 may also be such that multiple anti-slip protrusions 22 are provided in the axial direction of the side surface, or multiple anti-slip protrusions 22 are provided in the circumferential direction of the mounting portion main body 11 .
[0067] (8) In the third embodiment, the mounting body 11 has two movable parts 12 at opposite positions on the axis thereof, but the mounting body 11 may have a plurality of movable parts 12 regardless of their positional relationship with respect to the central axis thereof.
