Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a reel sheet for a fishing rod, and more particularly to a reel sheet capable of reliably preventing a nut from being loosened when the reel is mounted.

[0002]

2. Description of the Related Art In a fishing rod using a reel, the original rod is provided with a reel sheet for fixing a reel leg, and a reel is mounted via the reel sheet.
The reel sheet includes a pipe-shaped reel sheet body attached to the original rod, a pair of hoods provided on the reel sheet body for holding the reel legs from front and rear, and a screw formed on the reel sheet body. A nut having a matching nut is generally used.

In the hood, one hood is a fixed hood fixed to the reel seat body, and the other hood is a movable hood that can be moved back and forth in the rod axis direction by a nut. When attaching a reel to the reel sheet, insert one reel leg end into the fixed hood, and then move the moving hood while turning the nut to insert the other reel leg end into the interior. Then, the reel is fixed by tightening the nut.

When throwing a fishing line or winding a fishing line, a fishing rod is operated by gripping a reel leg and a reel sheet. For example, the reel leg is sandwiched between the index finger and the middle finger or between the middle finger and the ring finger, and the reel sheet and the pole are gripped by the entire palm. At this time, since the palm or the little finger contacts the nut for fixing the movable hood, the nut may be loosened by the movement of the hand or finger.

[0005] When the nut is loosened in this way, the reel leg is rattled (wobble), and the sense of stability is lost. As a result, there is a problem that the operation of the reel becomes extremely inaccurate and hinders the operation of the rod. In order to solve the problem, a reel sheet provided with an auxiliary nut for preventing the nut from being loosened, that is, a so-called double nut type reel sheet has been developed.

For example, those disclosed in Japanese Utility Model Publication No. 52-168888 and Japanese Utility Model Publication No. Sho 62-39670 (hereinafter, the features of the two publications will be briefly described). The former double nut structure, which has been filed by the present inventors, has a twill-shaped thread engraved on the outer peripheral surface of the seat body, and a fixing nut and a loosening of the fixing nut are provided on the thread. 6 is a reel sheet screwed with a loosening prevention nut for prevention.

Here, the screw directions of the fixing nut and the locking nut are formed in opposite directions. Therefore,
The fixing nut is completely locked (the rotation is restricted) by the locking nut, and the fixing nut is not loosened. Also, by making the screw directions of the two nuts opposite to each other, even if one of the nuts rotates,
The other nut does not rotate.

On the other hand, the latter double nut is a reel seat in which two nuts having different outer diameters are arranged on a tubular body (reel seat body). By making the outer diameters of the two nuts different from each other, the nuts are prevented from rotating together.

[0009]

However, in the case of Japanese Utility Model Application Laid-Open No. 52-168888, when the two nuts are rotated in opposite directions, when the reel legs are tightened and fixed, for example, the fixing nut is moved to the right. , And then turn the locking nut counterclockwise, which is very cumbersome.

When the reel is removed, it is difficult to determine the rotation direction for releasing the fixing of the locking nut, and the nut may be further tightened by mistake.
If the screw is screwed with an unreasonable force without knowing in this way, the male screw and the female screw may bite each other and may not come off with a slight force. In addition, when such a process is repeated, the pitch is broken and the screw thread is broken, so that the engagement between the two becomes weak.

On the other hand, in the latter case of Japanese Utility Model Publication No. Sho 62-39670, since the two nuts have different outer diameters, a step occurs when both nuts are fixed. Therefore, when the reel sheet is gripped, the presence of the step of the nut causes discomfort and the gripping property is deteriorated.

In this case, since the locking nut has a larger diameter, the palm, the little finger and the like are easily caught by the nut when gripped, and the nut is loosened as a result.
Further, since the locking nut protrudes outward and is exposed, the locking nut is conspicuous, and the external appearance is deteriorated.

[0013] Further, not only the above example but also the conventional double nut type reel seat is constituted by two ring nuts. Such a ring-shaped nut cannot be easily removed once it is mounted on the threaded portion of the reel seat body. Therefore, when foreign matter such as sand adheres to the screw portion of the reel sheet main body, maintenance such as cleaning is likely to be neglected.

The present invention has been made based on such a technical background, and aims at solving those problems. That is, an object of the present invention is to provide a reel seat structure capable of preventing looseness of a reel foot by reliably preventing loosening of a fixing nut in a double nut type reel seat. Also,
An object of the present invention is to provide a structure of a reel seat capable of quickly and accurately performing a nut rotation operation of a locking member in a double nut type reel seat.

It is a further object of the present invention to provide a reel sheet structure that improves the gripping property of the reel sheet, improves operability, and pursues simplicity in appearance. Another object of the present invention is to provide a structure of a double nut type reel sheet which can easily perform maintenance such as cleaning.

[0016]

Means for Solving the Problems The present inventors have conducted intensive studies on such problems, and as a result,
The present inventors have found that the conventional problems can be solved by allowing the nut of the locking member to be easily attached and detached in the double nut type reel sheet, and completed the present invention based on this finding.

That is, the present invention provides (1) a reel seat having a reel foot rest, a screw portion, a hood for inserting and fixing the reel foot, and a fixing nut for fixing the hood. The detachable loosening prevention member for prevention exists in the reel seat provided in the screw portion.

(2) The locking member is present in the reel seat, which is a half nut that can be screwed into the screw portion.

Further, (3) the notch portion of the half nut exists in the reel sheet whose angle is within 180 degrees.

(4) A reel sheet in which a pressing portion of a half nut is pressed against an inner peripheral edge of the fixed nut.

(5) The half-split nut is provided on a reel seat having elasticity so that it can be mounted from a direction perpendicular to the reel seat axis.

(6) A reel seat having a reel foot contact portion, a screw portion, a hood for inserting and fixing the reel foot, and a fixing nut for fixing the hood, in order to prevent the fixing nut from being loosened. A detachable half nut is detachably provided on the screw portion, the half nut has elasticity so that it can be mounted from a direction perpendicular to the reel seat axis, and has a cutout portion of the half nut. Is within 180 degrees and the pressing portion of the half nut is pressed against the inner peripheral edge of the fixed nut.

(7) The above (1) to (6)
In the fishing rod provided with any one of the reel sheets.

The present invention can also adopt a configuration in which two or more selected from the above 1 to 5 are combined as long as this object is met. Since the present invention has the above-described configuration, the loosening of the fixing nut can be reliably prevented. In addition, by making the locking member detachable, it is possible to easily and efficiently perform the work without mounting and removing the reel.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a reel seat structure having a loosening prevention function according to the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the entire fishing rod.
FIG. 2 is a partially enlarged view showing a state where a reel is attached to the reel sheet of the present invention. FIG. 3 is a development view showing the entire configuration of the reel sheet of the present invention.

As shown in FIG. 1, a reel sheet A is formed at a predetermined portion of the rod body of the former rod B, and a fishing reel R is mounted via the reel sheet A. The reel sheet A of the present invention is roughly divided into a pipe-shaped reel sheet main body 1 fixed to the original rod B, hoods 2 and 3 for inserting and fixing the reel feet R1, and the hood. It comprises a fixing nut 4 for fixing and a detachable locking member 5 for preventing the fixing nut 4 from loosening (see FIG. 3).

A reel footrest 11 for stably mounting the reel foot R1 is provided on the outer peripheral surface of the reel sheet body 1.
, A screw portion 12 for moving the hood, and a hood guide groove 13 for moving the hood. In the screw part 12,
As will be described later, a fixing nut 4 for fixing the floating hood 3
And a locking member 5 for preventing the fixing nut 4 from loosening. The screw portion 12 here is subjected to a thread cutting process in a certain direction.

The hood guide groove 13 is formed to be long in the axial direction of the reel seat body 1, and a protrusion 32 of a floating hood described later is engaged with the hood guide groove 13. The reel seat body 1 is provided with a pair of hoods for inserting and fixing the reel feet R1. Here, the fixed hood 2 is fixed to the rear part of the reel seat body 1, and the floating hood 3 is slidably mounted to the front part of the reel seat body 1. The pair of fixed hood 2 and floating hood 3 sandwich and hold the reel foot R1 from both sides.

A specific form of the fixed hood 2 is formed in a sleeve shape, and has a reel foot support 21 into which one foot of the reel foot R1 is inserted. The fixed hood 2 is securely fixed to the rear portion of the reel seat body 1 in a press-fit state, for example.

On the other hand, a specific form of the floating hood 3 is formed in a sleeve shape, and the reel foot R1 is provided inside the sleeve.
And a reel foot support portion 31 into which the other foot piece is inserted. The floating hood 3 is mounted on the front of the reel seat body 1 such that the reel foot support 31 is opposed to the reel foot support 21 of the fixed hood in the longitudinal direction.

The floating hood 3 has a projection 32 which can be engaged with the hood guide groove 13 of the reel seat body. The floating hood 3 can smoothly linearly move (slide) along the axial direction of the reel sheet main body 1 in a state where the rotation is restricted by the projections 32.

A fixed nut 4 screwed with the screw portion 12 of the reel seat body is rotatably connected to the floating hood 3. That is, the fixing nut 4 has a function of directly participating in the forward and backward movement of the floating hood 3. Therefore,
The floating hood 3 has a structure that can be linearly moved (slidable) back and forth along the longitudinal axis direction of the reel seat body 1 by rotating the fixing nut 4.

The inner peripheral surface of the rear end portion of the fixed nut 4 is not threaded (in other words, the screw portion 41 is not formed) (see an enlarged view of a main part of FIG. 2). Therefore, a certain gap S is inevitably formed between the reel seat body 1 and the fixing nut 4. Here, using the gap S, the pressing portion 53 of the locking member is pressed and fixed to the inner peripheral edge 42 of the fixing nut as described later. By the way, in order to prevent the finger from slipping, the gripping portion 43 in which the outer peripheral surface of the fixed nut 4 is subjected to unevenness processing, knurling or the like
Is more preferable.

In the present invention, the main feature of the locking member 5 for preventing the fixing nut 4 from loosening is shown. The locking member 5 has a function of reliably preventing the fixing nut 4 from loosening, and the locking member 5 is configured to be detachably attached to the screw portion 12 of the reel seat body. .

FIGS. 4A and 4B are views showing a locking member according to the present invention, wherein FIG. 4A is a side view thereof, and FIG. 4B is a sectional view taken along line AA in FIG. As shown in FIG.
As a specific embodiment, a half nut 5 formed in a C-ring shape having a notch 51 is employed. The locking member 5 having such a configuration can exert an elastic pressure function on the nut itself due to its unique shape. Therefore, as will be described later, the half nut 5 can be resiliently and removably attached from a direction perpendicular to the reel seat axis.

The notch 51 of the half nut must be provided within 180 degrees with respect to the circumference of the nut. That is, the notch portion 51 is cut in half or less with respect to the nut circumference. By doing so, the half nut 5 can be screwed into the screw portion 1 of the reel seat body.
2 can be reliably pressed and clamped to prevent falling off.

The inner peripheral surface of the half nut 5 has a screw portion 52 which can be screwed with the screw portion 12 of the reel seat body. One end of the half nut 5 is a pressing portion 53 formed in a tapered surface shape whose thickness gradually decreases. As described above, the pressing portion 53 of the half nut is a portion that is pressed into the gap S formed between the reel seat body 1 and the inner peripheral surface of the fixed nut. That is, the pressing portion 53 of the half nut
Presses against the inner peripheral edge 42 of the fixing nut.

On the outer peripheral surface of the half nut 5, a grip portion 54 which has been subjected to unevenness processing, knurling or the like is provided to obtain a slip preventing action. By providing such a grip portion 54, when the half nut 5 is fixed or the fixing state is released, the finger is prevented from slipping, and the half nut 5 can be turned with sufficient force.

The outer diameter of the half nut 5 is formed to have substantially the same outer diameter as the fixed nut 4. By doing so, there is no unpleasant grip feeling for the angler, and the reel sheet A has a simple shape, and the appearance is improved. However, since the half nut 5 is press-fitted to the fixed nut 4, it is needless to say that the outer diameter does not have to be the same. In addition, the half nut 5
As the material, a material having an elastic function, for example, a resin material, a metal material, a ceramic, or the like is employed, and preferably, plastic is used.

FIG. 5 is a diagram showing a procedure for attaching a reel (reel foot R1) to a reel sheet. In mounting the reel R on the fishing rod in the reel sheet A having the above-described configuration, first, the reel foot R1 is placed on the reel footrest 11 of the reel sheet. Then, the foot of one reel foot R1 is inserted into the reel foot support 21 of the fixed hood (see FIG. 5A).

Next, the fixing nut 4 is screwed forward while rotating in the right-handed screw direction (clockwise direction) to move the floating hood 3 forward along the longitudinal direction of the reel sheet main body 1 (FIG. 5B). See arrow). Incidentally, when the floating hood 3 moves, as described above, the floating hood 3 rotates in conjunction with the rotation of the fixing nut 4 because the projection 32 is guided along the hood guiding groove 13 of the reel seat body. Instead, it slides on the reel sheet body in a state where the rotation is restricted.

In this way, the floating hood 3 is slid along with the rotation of the fixing nut 4, and the foot of the other reel leg R1 is inserted into the reel foot supporting portion 31 of the floating hood. And the fixed hood 2 are sandwiched from front and rear. Then, by strongly tightening the fixing nut 4, the reel leg R <b> 1 is tightened by the floating hood 3, and the reel R is securely fixed to the fixed hood 2.

Next, the half nut 5 for fixing the fixing nut 4 to prevent loosening is fixed. Conventional (for example, Japanese Utility Model Publication No. 52-16
In the case of Japanese Patent No. 8888), the locking nut screwed to the thread of the seat body is rotated more than necessary from the rear to move it forward, and then tightened against the fixing nut. Therefore, troublesome nut operation was forced.

However, since the locking member according to the present invention is a half nut 5, it can be attached to the screw portion 12 of the reel sheet main body with one touch from a direction perpendicular to the reel seat axis. Therefore, it is possible to select an optimum position where unnecessary nut operation is not performed, and fit the half nut 5 into the screw portion 12 of the reel seat body. For example, if the half nut 5 is rotated two or three times, the fixing nut 4 can be fitted to a position where it can be securely fixed.

More specifically, when the half nut 5 is mounted, the periphery of the half nut 5 is pinched and pinched by a finger.
The notch 51 of the half nut is applied to the screw portion 12 of the reel seat body near the fixing nut 4 and the lower portion of the reel seat body 1 is directed downward (in the vertical direction of the arrow a).
Strongly (see FIG. 5B). Due to this pressing force, the half nut 5 is attached while being elastically pushed outward to spread over the screw portion 12 of the reel seat body. The half nut 5 that has been installed is
In a state in which the screw portion 52 and the screw portion 12 of the reel seat body are screwed together, the screw portion 52 is attached with a reliable holding force by the elastic pressure of the half nut 5.

Next, the half nut 5 is screwed forward while turning in the right-hand thread direction, and as described above, the pressing portion 53 of the half nut is brought into contact with the inner peripheral edge 42 of the fixed nut and the screw portion 12 of the reel seat body. It is guided to the gap S formed between them (see FIG. 5C). Then, while pressing the half nut 5, the pressing portion 53 is bitten into the gap S and is fixed in a press-fit state (see an enlarged view of a main part in FIG. 2).

In this case, the pressing portion 53 of the half nut is strongly pressed against the inner peripheral edge 42 of the fixed nut. By the way, since the half nut 5 is attached near the fixed nut 4, after the half nut 5 is attached,
It can be securely fixed by turning it three times. Therefore, it is not necessary to perform a complicated nut operation such as turning the nut many times as in the related art, and the nut operation is efficient.

In this manner, the floating hood 3 is pressed in the direction (axial direction) of the reel foot R1 and the fixed hood 2 via the fixed nut 4 and the half nut 5. In this case, since the pressing portion 53 of the half nut is press-fixed to the inner peripheral edge 42 of the fixed nut, the fixed nut 4 and the half nut 5 are restrained without moving each other and easily loosened. Never.

As described above, in the reel sheet A of the present invention, the fixing nut 4 can be securely prevented from loosening by the half nut 5, and the reel foot R1 is always in a stable state without rattling on the reel sheet. Installed with. Also,
The half nut 5 serving as a locking function of the fixing nut 4 can be quickly and accurately fixed. By the way, reel R
In order to remove the nut from the fishing rod, the operation of each nut described above may be performed in the reverse order.

That is, first, in step 1), the rotation restricted state (fixed state) of the fixed nut 4 and the half nut 5 is set.
Cancel. Next, in step 2), the half nut 5 is removed from the reel seat body 1. Next, in step 3), the fixing nut 4 is turned in the left-handed screw direction (counterclockwise) to retreat, and the floating hood 3 is moved rearward away from the fixing hood 2 with the rotation of the fixing nut 4. . Through such a procedure, the reel R can be easily removed from the fishing rod by releasing the reel foot R1.

Since the locking member 5 of the present invention is detachable, if the half nut 5 is removed after the above step 1), the nut operation of the following step 3) can be performed easily and quickly. be able to. 6 and 7 are views showing a procedure for removing the locking member. Note that the half nut 5 in FIGS. 6 and 7 is in a state in which the half nut 5 is turned back, for example, two or three times after the fixing with the fixing nut 4 is released.

In the method of removing the half nut 5 shown in FIG. 6, first, the grip portion 54 of the half nut is gripped with a finger (see FIG. 6A). Then, the nut 5 is slid upward (in the direction of arrow b) while being pinched and pinched by the finger. Then, the half nut 5 is removed while riding over the screw portion 12 of the reel seat body while being elastically pushed outwardly [see FIG. 6 (B)]. With such an operation, the half nut 5 can be easily removed with one touch. In addition, since the gripping portion 54 serving as a non-slip function is provided on the outer peripheral surface of the half nut 5, the finger does not slip when being removed.

In the method of removing the half nut 5 shown in FIG. 7, first, the periphery of the notch 51 of the half nut is pressed with a finger (see FIG. 7A). For example, one end is pressed with a thumb and the other end is pressed with an index finger. Next, the thumb holds the end of the half nut 5 as it is, and rotates the half nut 5 in the direction of arrow c with the fingertip of the index finger hooked on the end of the half nut 5 (FIG. 7). (B)). Again, with this operation,
The split nut 5 can be removed very easily.
By making the half nut 5 detachable, the operation of removing the reel R is simplified.

Although the present invention has been described above, the present invention is not limited to the embodiment, and it goes without saying that various other modifications are possible without departing from the essence of the present invention. For example, as long as the half nut can be detached from the outside, the design can be changed appropriately in addition to the case of the illustrated example.

[0055]

As described above, according to the present invention, in this type of double-nut type reel sheet, by securely preventing the fixing nut from being loosened, the reel is always attached to the reel sheet in a stable state. be able to. By making the locking member detachable, it is possible to easily and efficiently perform the work without mounting or removing the reel. Further, maintenance such as cleaning of the reel sheet can be easily performed. Furthermore, by making the outer diameter of the double nut substantially the same, it is easy to grip, thereby improving the operability. In addition, the appearance is improved. Further, in the case of manufacturing, even a double nut type reel sheet can be assembled with one nut, so that the number of manufacturing steps is reduced.
