Description

TECHNICAL FIELD The present invention relates to a ball net that is carried when fishing and has a structure of swinging out a plurality of nodes (tubular bodies), and a ball handle.

A ball net is mainly used when a fish is caught in a fishing spot where the distance from the angler to the sea surface is long, such as breakwater fishing or rock fishing. At such fishing spots, when taking in fish, the distance from the sea surface to the hand is long and there is a possibility that the fish may be separated, so a ball net is used to take in the fish. Normally, to catch a fish, operate the fishing rod with one hand to pull the fish close, grasp the base of the ball net with the other hand, sequentially feed the handle with a swinging structure to the sea surface, and then use the tip of the fishing rod. Fish are captured using a net attached to the net.

In the above-mentioned ball net, multiple nodes are sequentially stored in the base, and when the tip of the base is turned downward (sometimes by extrusion), each node protrudes in sequence. The knots do not fall out when the fish are caught, the rotation of the knots is regulated when they are protruded, and the joints of each knot are made easy so that they can be easily brought in when fish are taken in. Functions such as being able to easily remove the joints and retract and store them are required.

For example, Patent Document 1 discloses a ball net having the above-mentioned functions. The joint structure of each node of this bead net is such that a large diameter portion is formed at the proximal end of the front node, and a pair of protrusions that engage with the large diameter portion are provided at 180° intervals at the tip of the receiving node. There is. The outer peripheral surface of the large diameter portion is formed with unevenness having a triangular cross section over 360 degrees, and is prevented from rotating by engaging with the pair of projections. Further, the inner periphery of the tip of the receiving joint is made smaller in diameter, so that the large diameter portion of the front joint does not come off.

JP 2003-174835

In the conventional joint structure described above, a large diameter part is formed at the proximal end of the front section, and unevenness with a substantially triangular cross section is formed on the entire circumference of the outer circumferential surface, making it difficult to process the large diameter part. The problem is that it is difficult. In addition, with press-fit engagement along the axial direction of the unevenness and protrusion, when the joint is extended, the front joint may not be able to slide smoothly, and sticking may occur between the two, making the fish retrieval operation smooth. The problem is that it cannot be done.

The present invention has been made by focusing on the above-mentioned problems, and provides a ball net that allows easy processing of the joint structure between adjacent joints and allows for smooth fishing operation, and also provides such a ball net. The purpose is to provide bead handles used in nets.

In order to achieve the above-mentioned object, the present invention is a bead net having a joint structure in which a plurality of knots are housed in a base knot, and adjacent front knots and receiving knots are prevented from slipping out and being prevented from rotating. , the joint structure is provided with a large-diameter member that is attached to the proximal end of the front segment and has a polygonal cross section, and an inner surface of the tip of the receiving segment, and the large-diameter member is abutted to prevent the front segment from coming off. a small-diameter protrusion having a function; and a plurality of regulating protrusions that are provided on the inner surface of the tip of the joint on the proximal end side in the axial direction from the small-diameter protrusion and enter into the gap formed by the large-diameter member to regulate rotation of the large-diameter member. The regulating protrusion and the large diameter member are capable of engaging with each other with play in the circumferential direction.

The ball net having the above-mentioned configuration has a plurality of knots housed in the base knot in a swinging manner, and the net is attached to the tip knot. By grasping the main segment and pointing the tip downward, each segment will protrude, allowing you to pull fish close to the sea surface into the net. In this case, the adjacent front section and the receiving section are prevented from coming off and rotating by the joint structure when each section protrudes. In the joint structure, a large diameter member having a polygonal cross section attached to the proximal end of the front section is prevented from coming off by abutting against a small diameter protrusion provided on the inner surface of the distal end of the receiving section. Further, the large diameter member having a polygonal cross section is prevented from rotating by abutting against a regulating protrusion provided on the inner surface of the tip of the joint. Since the regulating protrusion and the large diameter member can be engaged with each other with play in the circumferential direction, the structure can be simplified and each joint can be smoothly inserted and removed.

Further, the present invention is a bead net having a joint structure in which a plurality of knots are housed in the base knot, and the adjacent front knots and receiver knots are prevented from falling out and being prevented from rotating, and the joint structure includes: a large-diameter member attached to the proximal end of the front section, extending in the axial direction and provided with a regulating section that restricts rotation of the front section; and a large-diameter member provided on the inner surface of the receiving section, against which the large-diameter member abuts. It has a small-diameter protrusion that has a function of preventing the front section from coming off, and an engaging section that is provided on the inner surface of the receiving section and extends in the axial direction to the base end, and that engages with the regulating section of the large-diameter member. It is characterized by

Even in the ball net with the above-described configuration, when the base section is grasped and the tip side is directed downward, each section will protrude, making it possible to capture fish drawn near the sea surface into the net. When each node protrudes, the adjacent front node and receiver node are prevented from coming off and rotating by the joint structure. In the joint structure, the large diameter member attached to the proximal end of the front section is prevented from coming off by coming into contact with the small diameter protrusion provided on the inner surface of the distal end of the receiving section. In addition, the large-diameter member is provided with a regulating portion, and this regulating portion extends in the axial direction on the inner surface of the receiving joint and engages with the engaging portion provided up to the proximal end. It is in a state where rotation is prevented, the structure is simple, and each joint can be smoothly inserted and removed.

According to the present invention, it is possible to obtain a ball net in which the joint structure between adjacent joints can be easily processed and a smooth operation for capturing fish, and a ball handle used in such a ball net.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a ball net according to the present invention will be specifically described with reference to the accompanying drawings.
FIG. 1 is a diagram showing an example of a ball net according to the present invention. The ball net 1 of this embodiment includes a root knot (tubular body) 10, knots 20, 21, 22, and 23 that are sequentially stored in the root knot 10 in a swinging manner, and a net 25 is provided at the tip of the diametermost knot 23. It has a fitted structure.
Although the number of knots is not limited, in this embodiment, it is made up of five knots, with four knots 20 to 23 housed in the original knot 10. Further, the lengths of each node 20 to 23 can be configured to be approximately the same length as the original node 10. Furthermore, each of these nodes does not need to be attached with the net 25, and can be manufactured and sold independently as a ball handle.

Each of the nodes 10, 20 to 23 is composed of a tubular body made of fiber-reinforced resin, and is made by impregnating reinforcing fibers (mainly carbon fibers, glass fibers, etc.) with thermosetting synthetic resin such as epoxy resin. The fiber-reinforced resin prepreg is wound around a core metal, subjected to a heating process, and then cored out to form a tubular shape of a predetermined size according to a standard method. Although each node in this embodiment has a tapered shape whose diameter decreases toward the tip side (net side), each node may have a straight shape.

A joint structure is provided at the tip and base end of each node to prevent the front node from coming off from the receiver node when the front node protrudes from the receiver node. A joint structure 30 is provided to restrict the rotation of. The joint structure 30 will be described below, but here it will be described as a joint structure between a base clause (also referred to as a receiving clause) 10 and a clause (also referred to as a front clause) 20.

2 and 3 are diagrams showing the first embodiment of the joint structure, in which FIG. 2 is a longitudinal cross-sectional view (a cross-sectional view taken along line BB in FIG. 3), and FIG. FIG. 2 is a sectional view taken along line AA of FIG.
The joint structure 30 of this embodiment is attached to the proximal end of the front section 20, and is provided on the large diameter member 31 having a polygonal cross section, and on the inner surface of the tip of the receiving section 10 (the inner surface near the tip opening), It is provided with a small diameter protrusion 33 which has a function of preventing the front section 20 from coming off by coming into contact with it when the large diameter member 31 protrudes.

The large diameter member 31 need only have a larger diameter than the outer diameter of the proximal end of the front section 20, and is press-fitted and bonded to the proximal end side of the front section 20. Although the material of the large-diameter member 31 is not limited, it is preferably molded from resin (including fiber-reinforced resin) to reduce weight. The large diameter member 31 has a polygonal cross section, and in this embodiment, as shown in FIG. 3, the large diameter member 31 has a hexagonal cross section. In this case, the large-diameter member 31 does not need to have a regular polygonal cross-section, and may be used as appropriate in relation to the storage space and the configuration of the regulating protrusion (provided on the receptacle 10) having the following anti-rotation function. It is possible to transform. Further, even if the shape is polygonal, a taper or a rounded surface may be formed at the corner.

The small-diameter protrusion 33 may be anything that reduces the diameter of the opening at the tip of the socket 10, and is provided by being integrally formed with the socket 10, or by adhering to the opening. Although the material of the small-diameter protrusion 33 is not limited, it is preferably made of resin (including fiber-reinforced resin) to reduce weight. For example, the small diameter protrusion 33 may be integrally formed in a ring shape as shown in FIG. It is possible to form.

The small-diameter protrusion 33 shown in FIG. 4(a) can be press-fitted into the tip opening and fixed with adhesive if the socket 10 is configured in a straight shape. As shown, if the small diameter protrusion 33 is formed with the notch 33a, the diameter can be reduced in the radial direction by pinching both sides of the notch 33a. Even if there is one, it can be inserted into the opening at the tip and easily adhered and fixed.
Even if the front section 20 tries to pop out from the receiving section 10, the small diameter protrusion 33 can be prevented from coming off by abutting the large diameter member 31 fixed to the proximal end side of the front section 20, and its shape, fixing method, etc. It is possible to modify it as appropriate.

The joint structure 30 is provided on the inner surface of the tip of the joint 10 on the proximal end side in the axial direction from the small diameter protrusion 33, into which the corner of the large diameter member 31 enters, and also restricts the rotation of the large diameter member 31. A plurality of regulating protrusions 35 are provided. The corner of the large-diameter member means an inflection point region of the surface caused by forming the large-diameter member into a polygonal cross-section.

As described above, since the large-diameter member 31 of this embodiment has a polygonal (hexagonal) cross-section, the portion that is close to the circular inner circumferential surface 10a of the joint 10, There are parts that are separated. The adjacent portions are some regions (corners) in the circumferential direction, and these regions exist in a plurality of locations at predetermined intervals along the circumferential direction. In FIG. 3, there are six proximate portions (proximate regions and corner portions), each of which is designated by a reference numeral 31a. Therefore, a gap S is created between the adjacent portions 31a in the circumferential direction, which are spaced apart portions, and the regulating protrusion 35 is provided so as to fit into this gap S. The regulating protrusions 35 are disposed on the same plane in a direction perpendicular to the axial direction, and a proximal portion 31a is provided between adjacent regulating protrusions 35 so as to regulate rotation of the large diameter member 31. I'm getting into it. In this embodiment, three regulating protrusions 35 are formed protruding from the inner circumferential surface 10a of the joint 10 at approximately equal intervals in the circumferential direction.

The regulating protrusion 35 may have any shape as long as it fits into the gap S, and may be provided by being integrally formed with the joint 10 or by adhering to the inner surface. Although the material of the regulating protrusion 35 is not limited, it is preferably made of resin (including fiber-reinforced resin) to reduce weight. According to the above-mentioned regulating protrusion 35, since the rotation of the large diameter member 31 at its corner (adjacent portion) 31a is regulated by the regulating protrusion 35, the rotation of the front section 20 is regulated.

The shape and arrangement of the regulating protrusion 35 can be modified as appropriate depending on the configuration of the large diameter member 31. For example, as shown in FIG. 5(a), if the large-diameter member has a substantially rectangular cross section, the region facing each side 31c becomes a spaced apart part and the above-mentioned gap S is formed. The protrusion 35 may be disposed so as to fit into this gap and face each side 31c. Further, if the large diameter member has a substantially regular hexagonal shape as shown in FIG. 5(b), for example, the area facing each side 31d becomes a spaced apart part and the above-mentioned gap S is formed. The regulating protrusion 35 may be disposed so as to fit into this gap and face the side 31d.

In the above configuration, when the front section 20 is made to protrude from the receiving section 10, the large diameter member 31 can enter inside each of the regulating projections 35 in the radial direction, as shown in FIG. Even if the large diameter member 31 attempts to rotate, the corner portion (proximate portion) 31a of the large diameter member 31 engages with the restriction protrusion 35, and the rotation is restricted. In this case, the regulation protrusion 35 can be engaged with the large diameter member 31 with a degree of play in the circumferential direction (in FIG. 3, the degree of play is the gap G between the corner 31a and the regulation protrusion 35). Although the rotation of the large diameter member 31 is restricted, it is configured such that some rotation is allowed.

Next, the effects of the joint structure 30 described above will be explained with reference to FIGS. 1 to 3.
During actual fishing, when a fish is hooked, one hand operates the fishing rod while the other hand operates the fishing net. When you pull the fish toward you, grasp the base segment (receptacle segment) 10, and turn the tip side downward, each segment 20 to 23 will protrude in sequence, and the joint structure 30 will connect the adjacent anterior segment and the segment. is prevented from coming off and rotating.

That is, when the front section 20 moves forward in the axial direction, the large diameter member 31 with a polygonal cross section attached to the proximal end of the front section 20 passes through the portion of the regulating protrusion 35 where the gap S is formed, It is prevented from coming off by coming into contact with a small-diameter protrusion 33 provided on the inner surface of the tip of the retainer 10. In this case, it is preferable that the tip of the large diameter member 31 be formed with an inclined surface 31A whose diameter decreases toward the tip so that the large diameter member 31 can smoothly abut against the small diameter protrusion 33. .

When the large-diameter member 31 is in contact with the small-diameter protrusion 33 and is prevented from coming off, the large-diameter member 31, which has a polygonal cross section, is in contact with the regulating protrusion 35 provided on the inner surface of the distal end of the joint. By attaching it, rotation is stopped. In this case, since the regulating protrusion 35 and the large diameter member 31 can be engaged with each other with some freedom in the circumferential direction, strict dimensional accuracy is not required, and the structure can be simplified. It becomes possible to process easily. Furthermore, the regulating protrusion 35 and the large diameter member 31 do not have a structure in which irregularities are continuously formed over 360° in the circumferential direction, but at predetermined intervals in the circumferential direction (in this embodiment, at approximately 120° intervals). Since it is configured to prevent rotation with three regulating protrusions), it is possible to improve the strength and also make it possible to smoothly insert and remove each joint.

In the above configuration, the circumferential freedom of the regulating protrusion 35 and the large diameter member 31 can be easily controlled by changing the shape, size, etc. of each member. When actually extending each joint to tackle a fish, if the rotation angle is too large, the maneuverability will deteriorate. That is, it is preferable that the degree of play is set to 60 degrees or less so that the frame 25A of the net 25 can be adjusted horizontally within the range of movement of the wrist. In particular, in a structure like this embodiment, in which there are five nodes and four joint structures are arranged, if the degree of play in each joint structure becomes too large, all nodes from the original node 10 will rotate. When doing this, the range of motion of the wrist may be exceeded. Therefore, when gripping the root node 10, the rotation between each node is 360 degrees or less, preferably 60 degrees or less per node, and the rotation of all nodes is 240 degrees or less. It is preferable to set the degree of play of the joint structure 30.

After taking the fish into the net 25, the fish in the net 25 can be taken out by pulling each section toward the front side with one hand and storing all the sections in the base section 10. Even in this hand-pulling operation, each joint is not restricted in the axial direction, so it is possible to carry out a smooth storage operation.

6 and 7 are diagrams showing a second embodiment of the joint structure of the front section and the receiving section, FIG. 6 is a longitudinal sectional view, and FIG. 7 is a sectional view taken along the line CC in FIG. 6. be.
Another embodiment of the present invention will be described below, but parts having the same functions as those of the above-described embodiment will be given the same reference numerals and detailed explanation will be omitted.

Each node 10, 20 to 23 of the beading net of this embodiment is composed of a straight tubular body. Further, the small diameter protrusion 33 and the plurality of regulating protrusions 35 are integrally molded from resin or the like. Specifically, as shown in FIGS. 8(a) and 8(b), the axial end edge 33A (the part that the large diameter member 31 abuts) of the cylindrical small diameter protrusion 33 is spaced approximately 120° apart in the axial direction. Three regulating protrusions 35 are integrally formed.

By integrally forming the small-diameter protrusion 33 and the plurality of regulating protrusions 35 in this way, it is easy to insert the small-diameter protrusion 33 and the plurality of regulating protrusions 35 into the distal end opening of the receptacle 10. The attachment work to the inner periphery of the tip can be easily performed. In particular, in this embodiment, since the joint 10 is formed in a straight shape, the assembly work from the distal end side of the joint 10 can be easily performed.

Further, in this embodiment, an engagement protrusion 60 is formed along the axial direction on the outer peripheral surface of the front end side of the front section 20, and the small diameter protrusion 33 of the receiving section 10 is provided with the engagement protrusion 60. A recess 33B is formed along the axial direction. The engagement protrusions 60 may be formed as thick parts, or may be formed in a plurality of protrusions at regular intervals in the circumferential direction. Further, the recess 33B may be formed so that the outer circumferential surface of the engagement protrusion 60 comes into contact with it and imparts a frictional force, and may be formed over 360 degrees, or the engagement protrusion 60 may be formed at regular intervals. In a configuration in which a plurality of protrusions are formed in the groove, it may be in the shape of a groove extending in the axial direction.

According to such a configuration, since the rotation of the front segment can be controlled at the initial stage of extending the segment, fluctuations in the position of the net 25 around the axis are suppressed, and there is no need to rotate the wrist more than necessary. It becomes possible to perform import operations smoothly.

FIG. 9 is a longitudinal sectional view showing a third embodiment of the joint structure of the front section and the receiving section.
The small diameter protrusion 37 of this embodiment is formed integrally with the small diameter protrusion 33 shown in FIG. 6 and a plurality of regulating protrusions 35, and has the function of preventing slippage and regulating rotation.

The small-diameter protrusion 37 has a diameter smaller than that of the large-diameter member 31 so as to prevent the large-diameter member 31 from coming off, and the small-diameter protrusion 37 has a diameter smaller than that of the large-diameter member 31 so as to prevent the large-diameter member 31 from coming off. It is sufficient to form a plurality of gaps, such as by forming a plurality of recesses along the circumferential direction on the proximal surface of 37.
Even such a small-diameter protrusion 37 can be easily inserted into the opening at the distal end of the receptacle 10, and can be easily attached to the inner periphery of the distal end of the receptacle 10.

10 and 11 are diagrams showing a fourth embodiment of the joint structure of the front section and the receiving section, FIG. 10 is a longitudinal sectional view, and FIG. 11 is a sectional view taken along the line EE in FIG. 10. be.
The joint structure 30 of this embodiment is provided with a small diameter protrusion 33 on the inner surface of the receiving joint 10, which has a function of preventing the front joint from coming off by abutting a large diameter member 38 attached to the proximal end of the front joint. There is.

As shown in FIG. 11, the large diameter member 38 has a ring shape, and a notch 38a extending in the radial direction is formed in a portion thereof. This notch 38a extends in the axial direction and has a function as a restricting portion that restricts rotation of the front section 20. In this embodiment, a notch 38a is provided on the inner surface of the joint 10 extending in the axial direction to the base end and engaged with the notch (regulating part) 38a so that rotation is regulated by the notch 38a. An engaging portion 40 is provided.

The engaging portion 40 of this embodiment can be integrally formed with the small-diameter protrusion 33 or the socket 10, and is configured as a protrusion extending in the axial direction. In addition, the engaging part 40 may be formed separately from the small-diameter protrusion 33 or the socket 10, and may have a structure that is attached to the inner surface of the socket 10.

According to such a configuration, since the engaging portion 40 formed on the inner surface of the joint 10 has a function as a guide rail, the front joint 20 moves in the axial direction without rotating with respect to the joint 10. This allows for smooth insertion and removal operations.

The engagement portion 40 that restricts rotation may be configured as a groove extending in the axial direction, and a protrusion may be formed on the large diameter member 38 to extend in the axial direction and engage with the groove. Further, it is preferable that the engaging portion 40 and the notch (restricting portion) 38a engage with each other with some degree of play in the rotational direction, as in the above-described embodiment. Furthermore, in the anti-rotation structure using such an engaging portion and a restricting portion, the engaging portions may be formed at a plurality of locations at regular intervals in the circumferential direction.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways.

The configurations of the large-diameter member and the regulating protrusion described above, as well as their locations and manner of arrangement, can be modified as appropriate. Further, the number and length of the knots (bead handles) of the ball net can be changed as appropriate. Moreover, the above-described joint structure may be disposed between any nodes, and a different joint structure may be disposed depending on the location. Furthermore, the present invention may be configured as a ball handle provided with the joint structure described above.
