[Problems to be solved by the invention]
The conventional ball net handle has a handle portion formed by connecting a certain number of tubular bodies, and the overall length when each tubular body is drawn out into a single tubular body is also determined. I have.
However, the length of the ball net handle required when fishing is not always constant. That is, the length of the handle of the ball net which is stretched out to scoop the fish varies depending on the conditions of the fishing place. Therefore, there is a demand for a ball net pattern that can be used by adjusting the length of the ball net pattern in a stretched state.
[0006]
An object of the present invention is to provide a ball net that can be used while a fisherman adjusts the length of a handle according to a situation.
[0007]
[Means for Solving the Problems]
The handle of Invention 1 is a ball net handle having at least a first tubular body and a second tubular body connected to the tip end side of the first tubular body in a swinging manner. Then, an engaging column that is detachably attached to the proximal end of the second cylindrical body and protrudes in the proximal direction at the proximal end surface, and a locking piece that protrudes in the radial direction at the capital of the engaging column. A front plug having a storage portion at the distal end side which is detachably attached to the proximal end of the first cylindrical body and which can store the engaging column, and has a notch through which a locking piece can be inserted. A rear stopper that has a flange on the distal end side around which the locking piece formed on the locking portion is locked, and restricts the circumferential rotation of the engaging column in a state where the locking piece of the front plug is locked on the flange. And a stopper mechanism.
[0008]
This ball net handle is used by connecting a net frame to the tip of the cylindrical body located at the tip end side. Each tubular body is housed in the form of a squirt in the tubular body located on the hand side sequentially from the tubular body located on the distal end side, and is housed in the second tubular body, and finally located closest to the hand side. It is housed in the first tubular body and becomes compact. Then, when catching fish hooked on a fishing rod, the net side is vigorously extended toward the surface of the water, and the cylindrical bodies are sequentially pulled out and scooped into the net at the tip as a single long handle.
[0009]
Here, the angler can adjust the pull-out length of the handle as follows. First, if the first tubular body and the second tubular body are kept free from each other, all of the tubular bodies jump out to the tip side and become the length of the entire tubular body. On the other hand, if the second cylindrical body is housed in the first cylindrical body and the two are engaged with each other and fixed, the length of the entire cylindrical body is equal to the axial length of the second cylindrical body. The drawer length becomes shorter than that.
[0010]
Specifically, in a state where the second cylindrical body is housed in the first cylindrical body, the front plug of the second cylindrical body is brought into contact with the rear plug of the first cylindrical body, and the two are relatively rotated. The engaging column is housed in the housing by rotating in the direction so that the locking piece of the engaging column of the front plug is aligned with the notch of the flange of the rear plug. Then, the both are relatively rotated in the circumferential direction, the locking pieces are locked to the flange, and the rotation in the circumferential direction is regulated by the stopper mechanism.
[0011]
The handle according to a second aspect of the present invention is the handle according to the first aspect, wherein the engaging pillar is a rectangular plate-shaped pillar, and a locking piece protrudes in a longitudinal direction of the end face of the capital of the engaging pillar. A concave ball receiver is formed on the end face. The rear plug has a passage communicating from the proximal end face to the storage portion, and includes a ball housed in the passage and partially protruding toward the storage portion, and a biasing spring for biasing the ball toward the distal end. are doing. The ball receiver and the ball are a stopper mechanism.
[0012]
In this handle, in order to engage and fix the second tubular body in a state where the second tubular body is housed in the first tubular body, the second tubular body is housed in the first tubular body. The front plug of the two cylindrical bodies is brought into contact with the rear plug of the first cylindrical body, and the two are relatively rotated in the circumferential direction, so that the rectangular plate-shaped engaging pillar of the front plug is engaged in the major diameter direction. Is fitted to the notch of the collar of the rear plug, and the engaging column is stored in the storage section. In this state, the ball of the rear plug protrudes from the passage toward the front plug by the biasing spring. Then, when the two are relatively rotated in the circumferential direction, the ball is fitted into the ball receiver on the end face of the capital of the engaging column, and the circumferential rotation of both is restricted in a state where the locking piece is locked to the flange. .
[0013]
To remove them, rotate them strongly in the circumferential direction and follow the reverse procedure.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a ball net adopting the first embodiment of the present invention includes a net frame portion 1 in which a net is attached to an annular frame, and a handle connected thereto. This ball net handle has a handle portion 2 composed of a plurality of cylindrical bodies, and a plug 3 for connecting the tip of the frame portion 2 and the net frame portion 1.
[0015]
The mesh frame portion 1 is formed by bending a metal member made of a stainless alloy, a titanium alloy, or the like into an annular shape, and forming the frame portion on the opening edge of a substantially cylindrical mesh made of a mesh-like braided yarn made of nylon fiber or the like. Through a combination of a frame and a net. Further, the frame portion has a groove formed on the annular outer peripheral surface and opened in the outer peripheral direction, and a metal or nylon core wire in which the opening edge of the net is locked is fitted into this groove and tightened, The net is fixed to the frame. Further, a male screw or the like is formed in a part of the frame portion, and the male screw portion is connected to the plug 3.
[0016]
The handle 2 is, for example, a portion formed by sequentially connecting five cylindrical bodies (the first cylindrical body 11 to the fifth cylindrical body 15 located closest to the hand). Each of the cylindrical bodies 11 to 15 is a tapered cylindrical member manufactured by winding a fiber reinforced resin in which a synthetic resin is impregnated with a synthetic resin into a reinforcing fiber such as a carbon fiber around a core material and firing it. These are connected in a so-called swing-out manner, and can be sequentially stored in the tubular body on the hand side. That is, the outer peripheral surface of the proximal end portion of each of the second cylindrical body 12 to the fifth cylindrical body 15 is a fitting male part (not shown), and each cylindrical body is sequentially pulled out and extended. At this time, they are sequentially fitted to the inner peripheral surface on the distal end side of the cylindrical body on the hand side. The inner peripheral surfaces on the distal end side of the first to fourth cylindrical bodies 12 to 14 are partially fitted into female female parts (not shown) by reducing the diameter. The taper of the outer diameter of each of the tubular bodies 11 to 15 is set to a constant taper ratio, and the outer diameter of each of the tubular bodies 11 to 15 is gradually reduced toward the distal end.
[0017]
The plug 3 is connected to the distal end of the small-diameter fifth cylindrical body 15 located at the distal most end. The plug 3 is made of, for example, a hard synthetic resin such as ABS or polycarbonate, rubber such as urethane rubber or styrene rubber, or a metal material such as stainless steel. The tip end of the fifth tubular body 15 is screwed or bonded in a state of being inserted into the end face of the plug 3 on the hand side. A female screw portion is formed on the end surface of the plug 3 on the distal end side, to which a part of the above-mentioned male screw of the frame portion is screwed. The outer peripheral surface of the plug 3 is set so that the tip end of the second tubular body 14 can be fitted. The mouth plug 3 acts as a stopper when each cylindrical body is stored.
[0018]
As shown in FIGS. 2 and 3, a front plug 20 is detachably attached to the proximal end of the second cylindrical body 12. That is, a screw groove is formed on the inner peripheral surface of the proximal end portion of the second cylindrical body 12, and the front plug 20 is detachably screwed to the screw groove.
The front plug 20 is a substantially cylindrical member with a lid having an open end on the distal end side and a closed end on the proximal side, and is made of a stainless alloy or the like. The front plug 20 has an externally threaded portion on the outer peripheral surface on the distal end side to be screwed into the above-described screw groove, and has a substantially rectangular column-shaped engaging column projected in the proximal direction protruding in the proximal direction on the proximal end surface. 20a, and a locking piece 20b that protrudes in the long diameter direction of the end face of the capital of the engagement pillar 20a. These are formed integrally. On the end face of the engaging column 20a (hand side), ball receiving portions 21 which are recessed in a spherical shape are formed at two places at intervals in the long side direction of the rectangle. In addition, a through hole is formed between the two ball receivers 21 so as to penetrate the engaging post 20a in the axial direction and reach the tip end side.
[0019]
In addition, a rubber plate 22 is arranged at an opening on the distal end side of the front plug 20 so as to close the opening. The rubber plate 22 serves as a buffer for receiving the third tubular body 13 and the like housed in the second tubular body 12.
On the other hand, as shown in FIGS. 2 and 4, a rear plug 30 is detachably attached to the proximal end of the first cylindrical body 11. Similarly to the front plug 20, a screw groove is formed on the inner peripheral surface of the proximal end of the first cylindrical body 11, and the rear plug 30 is detachably screwed thereto.
[0020]
The rear plug 30 is a substantially cylindrical member with a lid having an opening at the distal end surface and a closed end surface at the proximal end, and is made of a stainless alloy or the like. Further, similarly to the front plug 20, the outer peripheral surface on the distal end side of the rear plug 30 is also a male screw portion for screwing into the thread groove of the first cylindrical body 11, and the outer peripheral surface on the rear end side is one step larger. The diameter has become the knob. A knurl groove or the like for preventing slip may be formed in this knob portion.
[0021]
The inside of the front end side of the rear plug 30 is a storage portion that can store the engaging column 20 a of the front plug 20. The end edge on the distal end side is a flange 30a that protrudes in the inner diameter direction over the entire circumferential direction. A part of the flange 30a is cut in a pair at a position displaced by 180 degrees to form a notch 30b. The notch 30b matches the locking piece 20b of the front plug 20.
[0022]
On the other hand, a pair of through passages 30c is formed on the proximal side (rear end side) of the rear plug 30 so as to penetrate in the axial direction from the proximal end surface to the storage section. The formation position of the through passage 30c is at a position corresponding to the pair of ball receivers 21 of the front plug 20 described above, and the arrangement direction of the pair of through passages 30c is orthogonal to the formation direction of the notch 30b. ing. The opening at the tip end side exit (storage section side exit) of this through passage 30c is smaller in diameter than other portions. The inner peripheral surface on the hand side of the through passage 30c is a female screw portion. A ball 31 made of metal such as stainless steel is housed in the through passage 30 c, and a coil spring 32 is housed near the ball 31. The proximal opening is closed by the bolt 33, and the ball 31 is urged toward the distal end by the coil spring 32 in a state where a part of the ball 31 is exposed to the distal end.
[0023]
This ball net handle is used by connecting the net frame portion 1 to the plug 3 at the tip of the fifth cylindrical body 15 located at the most tip side. Each tubular body is housed in the form of a squirt in each tubular body located on the hand side sequentially from the fifth tubular body 15 located on the distal end side. When catching fish hooked on a fishing rod, the net frame 1 is vigorously extended toward the surface of the water, and the cylindrical body is sequentially pulled out to scoop the fish into the net at the tip as a single long handle. Put in.
[0024]
Here, the angler can adjust the first tubular body 11 and the second tubular body 12 to adjust the draw-out length of the handle 2 as follows. First, if the first cylindrical body 11 and the second cylindrical body 12 are set in a mutually free state, all of the cylindrical bodies jump out to the tip side and become the length of all the cylindrical bodies (for five). . On the other hand, if the second cylindrical body 12 is housed in the first cylindrical body 11 and is engaged and fixed to each other, the entire cylindrical body 12 is extended by the axial length of the second cylindrical body 12. The drawer length (for four) is shorter than the length of the shape.
[0025]
As shown in FIG. 2, in order to engage and fix the second cylindrical body 12 in a state where the second cylindrical body 12 is housed in the first cylindrical body 11, the second cylindrical body 12 is connected to the first cylindrical body 11. 11, the front plug 20 of the second cylindrical body 12 is brought into contact with the rear plug 30 of the first cylindrical body 11, and the two are relatively rotated in the circumferential direction, thereby engaging the front plug 20. The engagement piece 20 a is stored in the storage portion of the rear plug 30 by aligning the locking piece 20 b in the long diameter direction of the joint post 20 a with the notch 30 b of the flange 30 a of the rear plug 30. In this state, the ball 31 of the rear plug 30 projects from the passage toward the front plug 20 by the biasing spring 32. When the two members are relatively rotated in the circumferential direction, the ball 31 fits into the ball receiver 21 on the end face of the capital of the engaging column 20a, and the locking piece 20b is locked to the flange 30a. Rotation is regulated. Then, the first tubular body 11 and the second tubular body 12 are engaged and fixed. When removing both, it is sufficient to rotate the both strongly in the circumferential direction and perform the reverse procedure to the above-described case.
