[Problems to be solved by the invention]
However, in the engagement structure disclosed in Patent Document 1, when the movement guide is mounted on the collar and the top guide is arranged in a straight line, even if a mark as disclosed in Patent Document 2 is provided, They are not necessarily aligned in a straight line, and smooth anchoring that minimizes the resistance of fishing line feeding cannot be performed in the anchor anchoring. That is, the concave and convex strips provided on the inner periphery of the mounting cylinder of the moving guide are not necessarily fixed in the angular position with respect to the center line of each moving guide, and may vary within the range of one pitch of the concave and convex. Also, even when the angular position of the unevenness with respect to the center line of each moving guide is fixed and constant, the angular position relationship between the angular position of the unevenness and the cross-sectional non-circular shape of the saddle mounting seat is also determined. Therefore, they are not always aligned with high accuracy.
[0004]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fishing rod in which the movement guides are accurately aligned and arranged in a straight line and are held firmly.
[0005]
[Means for Solving the Problems]
In view of the above object, in claim 1 of the present invention, there is provided an outer guide type fishing rod having a top guide, which has a plurality of guide seats built up on the outer periphery of the fiber-reinforced synthetic resin front thin rod. The outer periphery of each guide receiving seat is provided with a plurality of concave and convex portions alternately in the circumferential direction and oriented in the longitudinal direction of the flange, and has a large radial drop or width compared to the concave and convex portions. , Guide strips oriented in the longitudinal direction of the rod, and the guide strips are arranged in a straight line in the longitudinal direction of the rod, and on the other hand, each moving guide mounted on each guide seat is mounted. On the inner periphery of the cylinder, it can be guided along the guide strip by engaging with the guide strip, and the moving guides related to the flanges are provided at the same angle positions with respect to the center line of each moving guide. Engaging cylinders and a number of cylinders that can be press-engaged with a number of irregularities of each guide seat Providing a fishing rod, characterized in that are provided with uneven conditions.
The guide strip is oriented in the extending direction, but it is not always continuous in the guide seat, and even if it is interrupted in the middle, it does not have to interfere with the guidance of the engaging portion of the mounting cylinder. The center line of the moving guide is a line connecting the center of the guide and the center of the mounting cylinder.
[0006]
Compared with a large number of concave and convex strips, the radial drop or width is large and the guide strip oriented in the longitudinal direction is provided, so that when the engaging portion of the moving guide is engaged, the engagement is prevented from being disengaged. The moving guide can be reliably guided along the extending direction of the guide strip. In addition, these guide strips are arranged in a straight line in the longitudinal direction of the flange, and the engaging portions are provided at the same angle with respect to the center line of each moving guide. The center lines of the respective movement guides are arranged on a plane including the center axis of the ridge. That is, the movement guides are arranged in a straight line. In addition, the guide tube and the engagement portion are not only engaged, but a large number of tube-side uneven grooves provided on the inner periphery of the mounting cylinder can be press-engaged with the many uneven grooves on the guide seat. Can be dispersed in the circumferential direction, and the movement guide is firmly held.
[0007]
According to a second aspect of the present invention, there is provided the fishing rod according to the first aspect, wherein the plurality of concave and convex portions have a front end at a rear position rather than a front end position of the guide strip.
As a result, the moving guide can be easily and reliably engaged with the guide strip by engaging the engaging portion of the mounting cylinder of the moving guide without being obstructed by the many uneven strips of the guide seat. It is possible to press and engage a large number of ridges by moving backward. Therefore, the mounting operation is easy and smooth.
[0008]

The fishing rod according to claim 1 or 2, which is provided on the upper side of the tip rod where the top guide is located.
Since it is a tip, if the moving guide is mounted on the guide seat, if the moving guide is visually aligned with the top guide, which is a large target, the engaging portion of the moving guide mounting cylinder is positioned on the guide strip. It becomes easy to engage with. In addition, since the guide strips are in the upper position aligned with the top guide in a straight line, the guide strips can be viewed together at the time of visual observation, and the moving guide can be more easily mounted.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings.
FIG. 1 is a top view of a front portion of an outer guide type fishing rod according to the present invention, and FIG. 2 is a side view thereof. In this form example, it is a swinging type fishing rod in which three of a marine rod (not shown), a middle rod 12 and a tip rod 10 are spliced together, but a parallel splicing type or the like may be used. Each kite is a fiber reinforced resin kite made of a synthetic resin such as an epoxy resin and reinforced with carbon fiber or other reinforced fiber. However, the tip rod 10 may be a hollow tube or a solid rod. A top guide TG is fixed to the tip collar, and in this example, guide seats Z1, Z2, and Z3 are provided on the outer periphery of three locations in the longitudinal direction of the tip collar. Furthermore, guide seats (not shown) are provided in the middle collar 12 at two locations.
[0010]
The guide seat is formed integrally with the ridge using fiber reinforced resin, synthetic resin, or the like. Movement guides YG1, YG2, and YG3 can be attached to the guide seats, respectively. There are also two movement guides (not shown). As described above, since it is a swing-out type, the movement guide YG3 attached to the rearmost guide receiving seat Z3 can pass through the front guide receiving seats Z2 and Z1, and the moving guide YG2 is also the same. It can pass through the guide seat Z1, and each moving guide is collected near the top guide TG at the time of storage.
[0011]
Below, the guide seat Z2 and the movement guide YG2 will be described as representatives, but the same applies to the rest. FIG. 3 shows an enlarged longitudinal sectional view of a portion of the guide seat Z2. 4 is a cross-sectional view showing a state in which the movement guide YG2 is mounted on the same part, FIG. 5 is a view of only the movement guide YG2, and FIG. 6 is an enlarged view of the main part of FIG. On the outer periphery of the guide seat Z2, a large number of concave and convex strips OT2 and one relatively large guide strip G2 extend in the longitudinal direction of the ridges. There may be two or more guide strips, but the number of guide strips is small. Further, the front end position P2 of the concave and convex strip is a rear position from the front end position P1 of the guide strip G2.
[0012]
The movement guide YG2 has a hard guide ring R2 made of ceramics, a mounting cylinder T2 for mounting on the saddle 10, and a frame portion F2 connecting them. On the inner periphery of the mounting cylinder, one recess is provided as an engaging portion TG2 to be engaged with the guide strip G2, and a number of projections and depressions TO2 are formed in the other inner peripheral region. In this example, the recess TG2 is provided so that the center is located on the center line L1 of the moving guide connecting the center C1 of the guide ring and the center C2 of the mounting cylinder. On the other hand, the guide strip G2 is positioned on the plane H1 including the center of the guide ring of the top guide and the central axis of the tip, and is provided on the top guide side in the circumferential direction. Therefore, if the concave groove of the movement guide is engaged with the guide groove of the guide seat, the relative position of the movement guide in the circumferential direction with respect to the guide seat is determined, and in this state, the movement guide is aligned with the top guide. .
[0013]
As described above, since the front end position P2 of the concave and convex strip is a rear position from the front end position P1 of the guide strip G2, at the start of mounting engagement of the movable guide, a large number of concave and convex strips of the guide seat and the movable guide are provided. Since the large number of projections and depressions on the side do not engage with each other, the movement guide can be easily engaged and stabilized.
[0014]
In this example, a large number of concave and convex strips OT2 on the guide seat side and a large number of concave and convex strips TO2 of the moving guide have concaves and convexes formed at a predetermined pitch, and the pitch angles are the same. Furthermore, if the moving guide is pushed halfway in the guide seat, the outer diameter and inner diameter dimensions are set so that the two ridges are pressed and engaged with each other. Further, the circumferential gap between the guide strip G2 and the concave strip TG2 is preferably 1/4 or less or 1/5 or less of the pitch of the concave and convex strips. If it is too large, the circumferential relative position of the moving guide with respect to the flange cannot be positioned. In addition, in a tightly fitted state with no gap, there is a problem in the work of attaching and removing the movement guide, and therefore the existence of a very small gap is preferable.
[0015]
The height of the guide strip is higher by H than the height line S on the surface of the convex portions of a large number of concave and convex strips OT2. Although this H depends on the position of the guide seat, it is preferably about 0.1 to 1 mm, but it may be larger or smaller than this. The bottom of this guide strip is made to coincide with the concave strip of the uneven strip. The presence of the height difference H expresses that the radial drop is large in the claims. However, contrary to this example, the guide strip may be a concave strip, and the engaging portion TG2 on the inner periphery of the mounting cylinder T2 may be a convex strip. In this case, the large radial head means that the bottom of the concave strip that is the guide strip is lower than the bottoms of the concave strips of the many strips. Further, the width of the guide strip may be large.
[0016]
In this example, each of the concave and convex strips of the guide seat and the mounting cylinder has a constant pitch in the circumferential direction and the height and depth of the concave and convex portions, and both pitches are set to the same value. The number of irregularities is also matched. Further, the concave and convex groove depth is increased on the cylinder side. Therefore, in a state where the moving guide is mounted on the guide seat, the recesses of the guide seat and the projections of the mounting cylinder are pressed, and a pressing force acts on the entire circumference of the guide seat. , Can hold firmly. Further, the depth of the engaging portion TG2 is sufficiently deeper than the height of the guide strip G2, and the concave and convex strips can be sufficiently pressed. Moreover, the width | variety of a guide strip is formed larger than the pitch of an uneven strip. Specifically, it may be 1 to 3 mm.
[0017]
Unlike the above example, the concave / convex pitch of a large number of concave / convex strips OT2 and TO2 may not be constant, and both pitches may not be the same and may be different. Furthermore, the number of irregularities may not be the same. Accordingly, the ridges on the mounting cylinder side are not pressed against all of the ridges on the guide seat side, but this is not necessary because they do not change in pressing at various positions in the circumferential direction. Furthermore, the angle range in which a large number of uneven strips are provided is preferably the entire remaining region excluding the guide strip region, but may be a part thereof. For example, 180 degrees.
[0018]
The form of the guide seat in the length direction will be described. Although the height (thickness) of the guide strip G2 from the surface of the front thin ridge 10 may be constant from the front end to the rear end, it may be set higher toward the rear. Further, the bottom thickness t of the concave stripes of the multiple concave and convex stripes OT2 may be constant from the front end to the rear end, or may be set thicker toward the rear. In this example, the thickness is gradually increased from the front end P1 to the rear position P3, and thereafter, the thickness is set to be steeply tapered until the rear end P4.
[0019]
This prevents a problem that the moving guide is moved too far backward and falls back. Further, the height difference (groove depth) f between the top surface of the ridge and the bottom surface of the ridge is substantially constant except between the positions P3 and P4, and the depth is gradually brought closer to 0 from the positions P3 to P4. Yes. In any case, since the height of the bottom surface of the concave and convex ridges increases toward the rear, the guide seat can be pressed and held by moving the moving guide backward.
[0020]
Although the area | region which does not form many uneven | corrugated strips is provided in the rear-end part and front-end part of a guide seat, you may provide in all the areas. Further, the front end of the guide strip and the front end of the concave and convex strip may be matched, or conversely, the front end position of the concave and convex strip may be positioned on the front side. Furthermore, in order to reduce the level difference between the front end and the rear end of the guide seat and to facilitate the mounting of the moving guide, the inclined portion Z2 ′ may be provided with synthetic resin or paint. This also helps prevent stress concentration.
[0021]
In the above example, the guide strip G2 is provided so that the center is positioned on the upper side of the heel on the plane H1 including the guide ring center of the top guide and the central axis of the tip heel, but the diametrically opposite direction of the heel You may provide in the side, ie, the lower side. Moreover, you may provide in the left side and the right side. Further, any two or more of these may be provided together. In these cases, the engaging portion TG2 on the mounting cylinder side is naturally provided at a position corresponding to these angular positions.
[0022]
A method for making the groove depth f constant in the circumferential direction will be described below.
A step of integrating a guide seat outside a predetermined position of the fiber-reinforced synthetic resin cage, and processing the outer periphery of the guide seat (region excluding the guide strip portion) into a circle with a predetermined accuracy; And a step of machining grooves extending in the longitudinal direction in the guide seat on the basis of the outer periphery of the guide seat, and the depth of a plurality of grooves having a predetermined pitch is made substantially constant in the circumferential direction.
Predetermined accuracy means that the minimum length (radius) to the outer periphery of the guide seat measured at the center of the smallest circumscribed circle (radius R1) circumscribing the processed outer periphery of the guide seat is R2, and R1-R2 = Δ Means 0.05 mm or less, preferably 0.03 mm or less.
[0023]
When a groove extending in the longitudinal direction is machined in the guide seat on the basis of the outer circumference of the circular guide seat, the guide seat is gripped with a chuck or the guide seat is received by the receiving tool when the groove is machined. In the former case, the axis of the chuck coincides with the axis of the guide seat (that is, the spatial position of the center axis of the chuck can always be captured (typically at a fixed position). Therefore, the axis of the guide seat can always be captured at the same position (typically at a fixed position)), and in the latter case, the guide seat indexed from the receiving surface of the support The aim is to always be able to capture the axis (typically at a certain position).
[0024]
Even if the guide seat processed into a circular shape is rotated, a circular outer periphery with a predetermined accuracy is used as a reference, so that the axis of the guide seat can be maintained unchanged. Therefore, the outer periphery of the guide seat to which the groove is to be machined can always be maintained at the unchanged position regardless of the rotation. That is, for example, the spatial position such as the height of the outer periphery of the guide seat determined by measurement or the like before grooving can always be kept constant depending on the rotation. Therefore, the depth cut from the outer surface of the guide seat at the time of processing the first groove can be maintained without repeating measurement and the like even if it is rotated later, and the depth in the circumferential direction of the guide seat is approximately the same. Many constant grooves can be easily formed.
Each item described in different embodiments can be applied to other embodiments as long as no contradiction arises.
