Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a depth gauge for fishing gear, and more particularly to a depth gauge for fishing gear that has a mounting structure that can be easily fixed to fishing rods of various sizes.

2. Description of the Related Art A depth meter for fishing gear is composed of a pulley around which a fishing line goes around, and a cylinder-type counter that is activated by the rotation of the pulley to display the depth, and the fishing line is reeled out from a reel. It is known that the depth gauge is set by rotating the depth gauge around the pulley.

With this type of depth meter, the fishing line can be unwinded (unwound).
The pulley is rotated accordingly. Therefore,
By rotating the counter through a gear reduction mechanism with an appropriate reduction ratio, the reading on the counter can directly indicate the depth position of the fishhook.

The depth gauge for fishing gear as described above must be firmly fixed to the fishing rod. This is because a fishing rod is shaken a lot when the hook is put into the water or taken out, and is also subjected to tensile force from the fishing line, so if it is not firmly fixed, it will easily loosen and cannot be used for practical use.

For this reason, conventional depth gauges for fishing gear generally have a mounting structure in which a mounting guide slot member is fixed to the fishing rod in advance, and a mounting plate fixed to the depth gauge body is slid along the mounting guide slot member. The mounting structure is such that it is fixed in place so that it cannot fall off.

Problems with the Prior Art In such a mounting structure, the guide slot member for mounting must be fixed in advance to a predetermined position on the fishing rod. This fixing is normally done during the manufacturing of fishing rods, and it is therefore extremely inconvenient that this type of depth gauge cannot be attached as is to a fishing rod without this preparation. In addition, although the guide slot member for attachment may be personally fixed to the fishing rod, this work is relatively troublesome and requires skill, and cannot be easily performed by an amateur. Despite these problems, no fishing rod has been provided with a mounting structure that allows a depth meter to be securely and easily fixed to any fishing rod.

Purpose of the invention In view of the above-mentioned installation problems, the purpose of the invention is to provide a depth gauge for fishing gear that can be easily and firmly fixed to any fishing rod without requiring any preparation. The goal is to provide the following.

Summary of the invention To this end, the depth meter for fishing gear according to the invention is characterized by the following structure. That is, it has a pulley that circulates the fishing line and a counter mechanism that is operated by the rotation of the pulley, transmits the amount of fishing line let out as a rotational movement to the counter via the pulley, and reads the display on the counter. A main body of a depth meter for fishing gear that can be used to determine the depth, an elongated stationary side plate fixed to the main body and formed so as to be in close contact with one side of a fishing rod; a mounting rod, a guide rod erected from the main body of the depth gauge in parallel with the mounting rod, and openings through which the mounting rod and guide rod are respectively inserted, and each of the above-mentioned holes is formed in each opening. a movable plate that can be moved in parallel along both rods so as to approach and move away from the fixed plate by inserting a rod therethrough; and a movable plate that is attached to the mounting rod from the outside of the movable plate. and a tightening handle, wherein the mounting rod has a groove formed along its length, and the mounting rod extends from one side of the groove toward the vicinity of the opposite side. A plurality of engagement grooves extending along the circumferential surface are formed at regular intervals in the rod axial direction, and the engagement grooves are formed at an angle of approximately 90° to 180° in the circumferential direction from the one side surface. A helical groove such as a screw groove is formed in the range of 1.5°, and a groove portion continuing from the helical groove is a circumferential groove extending along a plane perpendicular to the axis of the mounting rod, and the above-mentioned The mounting handle is configured to be mounted on the mounting rod by forming an opening through which the mounting rod is inserted, and the mounting handle has an opening formed in the mounting rod on the inner peripheral surface of the opening. At least one protrusion is formed that can be inserted into the groove and can also be inserted into the engagement groove by rotation of the tightening handle, and furthermore, the tightening handle is connected to the movable side plate. A raised part is formed on a part of the abutment surface, and the tightening handle is formed on the surface of the movable plate opposite to the raised part with the protrusion positioned in the groove of the mounting rod. It is characterized in that a recessed portion having a slope is formed.

The invention will be explained below by way of example with reference to the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 1 schematically shows a depth meter for fishing gear according to the present invention. As is well known, this depth gauge itself has a pulley 1 for rotating the fishing line 1 and a counter mechanism 2 that is operated by the rotation of this pulley 1, and the amount of the fishing line 1 to be fed out is controlled via the pulley 1. The structure is such that the depth can be determined by transmitting the rotational motion to the counter mechanism 2 and reading the display 3 on the counter. Since the present invention is not concerned with such a mechanism itself, it will not be described in further detail.

In FIG. 1, a fixed side plate 20 is integrally formed on a main body 10 of a depth meter for fishing gear. This fixed side plate 20 has an appropriately curved inner surface 20a so as to be in close contact with one side of a fishing rod (not shown), and is formed to have an appropriate length along the fishing rod. It is said to have an elongated shape. Of course, this stationary side plate can be formed separately and fixed to the main body 10 by suitable means such as screws.

Also, two rods, namely the mounting rod 21
A guide rod 22 and a guide rod 22 are erected from the main body 10 in parallel. Of course, these rods can also be fixed separately. A movable plate 23 formed with holes 23a and 23b for receiving these rods, respectively, is attached to both rods as shown. Like the fixed side plate 20, this movable side plate 23 is also formed of an appropriate length and has an appropriately curved inner surface 23c so as to be in close contact with the other side of the fishing rod. 21, 22 so as to be able to move in parallel, and a fishing rod can be held between the inner surface 23c and the inner surface 20a of the fixed plate 20. These inner surfaces 2
It is desirable to further fix anti-slip materials such as rubber (not shown) to 0a and 20c.

The mounting rod 21 has a movable side plate 23.
A tightening handle 24 is attached from the outside of the
By operating this tightening handle 24, the fishing rod can be tightened and fixed as will be described later.

Here, a compression spring (not shown) is installed between the fixed side plate 20 and the movable side plate 23, for example, around the mounting rod 21, so that the movable side plate 23 is always connected to the fixed side plate 23.
It is preferable in terms of installation operation that it be separated from the base. Further, it is preferable that a means such as an E-ring is provided on the distal end side of the attachment rod 21 to prevent the tightening handle 24 from falling off.

According to the invention, the mounting rod 21 has a second
As shown in the figure, a groove 30 is formed along the longitudinal direction. Also, one side surface 30 of this groove 30
A plurality of engagement grooves 31 extending along the circumferential surface of the attachment rod toward the vicinity of the opposite side surface are formed at regular intervals in the axial direction of the rod. The other end of this engagement groove 31 does not reach the other side surface 30b of the groove 30. That is, the groove 30 and the engagement groove 31 are connected only at the side surface 30a.

As a feature of the present invention, as shown in FIG. 2, the engaging groove 31 has a thread-like groove in the range of approximately 90° to 180° in the circumferential direction from the side surface 30a of the groove 30. A spiral groove 31a is formed, and a groove portion 31b continuing from the spiral groove 31a is a circumferential groove (31b) extending along a plane perpendicular to the axis of the mounting rod 21. For easier understanding, a developed view of the engagement groove 31 is shown in FIG. 3, and as shown here, the engagement groove 31 is constructed as a continuation of two groove portions, a spiral groove 31a and a circumferential groove 31b. The shaded part is the part of the mounting rod 21 that forms the wall surface of the engagement groove 30, and is designated by the reference numeral 31c.
It is preferable to increase the opening area of the engagement groove 31 relative to the groove 30 as shown in FIG.

As shown in FIGS. 4 and 5, the tightening handle 24 has a boss portion 24a and a handle portion 24b.
It is formed with The boss portion 24a is formed with an opening 40 through which the mounting rod 21 is inserted, as shown in FIG.
A protrusion 41 is formed that protrudes inward from the inner peripheral surface. This protrusion 41 is inserted into a groove 30 formed in the mounting rod 21, thereby allowing the tightening handle 24 to be mounted on the mounting rod 21 and rotating the tightening handle 24. This allows it to fit into the engagement groove 31. Therefore, the size of this protrusion 41 is selected in accordance with the dimensions of the groove 30 and the engagement groove 31. Further, the number of protrusions 41 is not limited to one; for example, in this embodiment, there are two as shown in FIG. 6, and a plurality of protrusions can be formed as desired. In this case, the individual protrusions 41 are separated by a distance corresponding to the spacing pitch of the engagement grooves 31. Furthermore, as shown in an enlarged view in FIG. 7, the cross-sectional shape of the protrusion 41 may be partially cut to have a pointed end, thereby facilitating the engagement into the engagement groove 31. It is possible.

Furthermore, the tightening handle 24 is mounted on the mounting rod 21 from the outside of the movable plate 23 as shown in FIG. That is, here, the end surface 25 of the boss portion 24a has a raised portion 25.
a is formed. As shown in FIGS. 6 and 8, this raised portion 25a is shaped like a triangular pyramid. On the other hand, as shown in FIG. 8, a recessed portion 23d having a slope for receiving the raised portion 25a is formed on the surface of the movable plate 23 constituting the abutment surface. This recessed portion 23
d, the protrusion 41 of the tightening handle 24 is in the concave groove 3.
0, the raised portion 25
It is formed at a position opposite to a. Furthermore, apart from the slope for forming this recessed portion 23d,
As shown in FIG. 9, an opening 23 for the mounting rod 21 is formed in the movable plate 23.
Along the circumference of a, here the mounting rod 21
Circumferential groove 31b in the engagement groove 31 formed in
Corresponding to the angular range, a slope 23e is formed which is gradually raised opposite to the recessed part 23d.

Explanation of operation The depth meter for fishing gear according to the present invention having such a configuration is assembled as shown in Fig. 1.
When attaching to a fishing rod, position the protrusion 41 of the tightening handle 24 in the groove 30 of the attaching rod 21 and move it to the outermost position, then move the movable plate 2
3 is separated from the fixed plate 20, and the fishing rod is positioned between the fixed plate 20 and the movable plate 23. At this time, if the movable side plate 23 is forcibly pressed in the direction of separation using a compression spring (not shown) or the like, the operation will be easier.

Next, press the movable side plate 23 against the fishing rod,
Similarly, the tightening handle 24 is pressed toward the fishing rod and rotated. This rotation is performed in the direction of engaging the protrusion 41 formed on the tightening handle 24 into the engagement groove 31 (it cannot rotate in the opposite direction). Due to this rotation, the protrusion 41 first moves into the spiral groove 3.
1a, so that the tightening handle 24 is connected to the fixed side plate 20 and the movable side plate 2.
3 increases the gripping force of the fishing rod, and achieves strong and reliable attachment and fixation to the fishing rod. Subsequently, the tightening handle 24 is further rotated to push the protrusion 41 into the circumferential groove 31b. This circumferential groove 31b
Since this is not a spiral groove, the state of engagement with the protrusion 41 itself can prevent the risk of loosening and rotation due to pressing reaction force, while the tightening handle 24 is rotated along this circumferential groove 31b. The raised portion 25a of the movable side plate 23
It gradually climbs onto the top of e. Due to this riding, the additional tightening force applied to the movable plate 23 is further increased, and the protrusion 41 is pressed against the one side wall within the circumferential groove 31b, thereby further enhancing the above-mentioned loosening prevention function.

Furthermore, by rotating the tightening handle 24,
The recessed portion 23d formed on the contact surface with the movable plate 23 and the raised portion 25a formed on the tightening handle 24 rotate relative to each other, and the raised portion 2
5a is moved along the slope of the recess 23d. This movement acts to press the movable plate 23, and at the same time serves as a reaction force to press the protrusion 41 to one side within the circumferential groove 31b. Therefore, loosening of the tightening handle 24 is more reliably prevented.

Effects of the invention The depth meter for fishing gear according to the invention as described above has the following effects.

The simple mounting structure allows for extremely easy and reliable mounting on a fishing rod.

The fishing rod does not require any prior preparation for this installation.

It can be attached to and detached from any fishing rod, regardless of the size of the fishing rod.

It won't damage your fishing rod.
