Description

The buoyancy of the fishing float can be freely changed, and two types of fishing floats with different structures can be used together in one fishing float.

Conventional fishing floats are made by changing the weight stored inside the fishing float body in a space that is sealed and isolated from the outside world, changing the air volume inside the fishing float body that is sealed and isolated from the outside world, or changing the air volume inside the fishing float body that is sealed and isolated from the outside world. A fishing float whose buoyancy can be adjusted by injecting water into the isolated fishing float body is now on sale.

There are many different types of fishing floats, among which there are threaded floats in which the fishing line passes through the inside of the float, and ring-type floats in which a ring is provided at the bottom of the float and the ring portion is connected to the fishing line with a snap. Floating is the mainstream.

The technology disclosed in the above-mentioned Patent Document 1 provides a waterproof function and a sealed space inside the fishing float, and adjusts the volume of air inside the fishing float by changing the volume within that space. This makes it possible to adjust the buoyancy of the fishing float itself. By changing the buoyancy of this fishing float, it is possible to change the fishing method and device to suit various situations, and it is popular with many users. There are issues as described below.

The above-mentioned fishing float has a structure in which the buoyancy of the fishing float itself can be changed by changing the volume of air inside the fishing float as desired by the user. There is a problem in that it is difficult to understand the amount of change in buoyancy given to the fishing float because of the changes. In addition, the inside of the fishing float has a sealed space that is processed to prevent water from entering, and weights can be stored in that space, and the number, size, and mass of the stored weights can be changed to create a fishing float. There are also fishing floats that have a structure that allows you to change the buoyancy of the float. However, if you change the size of the weights stored or change the number of weights, the total volume of the stored weights will change, causing a change in air volume in the space where the weights were stored, resulting in accurate floating. It is difficult to understand the amount of change in buoyancy.

The technology disclosed in Patent Document 2 mentioned above is such that when a fishing float is floated on the water surface in a fishing float body, a weight is placed on the water surface in a space for storing a buoyancy adjustment weight provided on the floating fishing float. It has been proposed to create a structure that fills water with atmospheric pressure so that only the exchange of the stored weight or the subtracted mass of the weight will affect the buoyancy of the fishing float, making it possible to accurately determine changes in the buoyancy of the fishing float. However, there are issues described below.

The above-mentioned fishing float has no space to store the weight for buoyancy adjustment on the vertical center line of the center of gravity, so that when the fishing float is floated on the water surface, the fishing float floats vertically and stably. The mass of the weight that can adjust the buoyancy within the range that allows the fishing float to maintain its vertical posture is extremely small, and it is conceivable that the range of buoyancy changes will be small. In addition, because the water injection hole provided to fill the space for storing the buoyancy adjustment weight with water is located at the top of the float, the space for storing the buoyancy adjustment weight cannot be filled with water smoothly. There's a problem.

There are many types of fishing floats available to the public, such as hollow floats and ring floats. These fishing floats are stable and have constant buoyancy, and are trusted and well received by users, but they have the following problems.

There are two types of fishing floats based on their structure: the above-mentioned hollow floats, through which the fishing line passes inside, and the ring-equipped floats, which are connected to the fishing line with a snap or similar to a ring provided at the bottom of the fishing float. Due to structural differences, the two types of fishing floats cannot be used together in one fishing float. In addition, fishing floats with variable buoyancy, which have a closed space inside and allow weight to be put in and taken out of that space, have a pipe in the center of the float to pass the fishing line through. In addition, commercially available round weights cannot be stored in the center of the float and are biased to one side, which may cause the float to tilt when floating on the water surface. Furthermore, since the pipe for passing the fishing line is located in the center of the float, it is not possible to provide a space for storing the weight. Therefore, a fishing float whose buoyancy can be changed by inserting and removing a weight inside the float has not yet been put into practical use.

The present invention has a through hole (1) in the central axis of the fishing float, and when the fishing float having the through hole (1) is floated on the water surface, the atmospheric pressure applied to the water surface causes the fishing float to float. A structure is provided to fill the inside of the through hole (1) with water. The water line (13) of the fishing float floating on the water surface and the height (14) of the water surface inside the through hole (1) are the same. A structure is provided in which the weight for buoyancy adjustment can be held or taken out in the through hole (1) filled with water to change the weight of the weight.

A fishing float is provided with a mechanism for supplying and draining water inside the through hole (1) on the central axis of the fishing float, and by utilizing the mechanism, a fishing float is used in which a fishing line is passed through a pipe provided inside the fishing float; The fishing float has a ring (9) at the bottom of the fishing float for holding the float to the device. Two types of floats with different structures can be used together with one fishing float by simply replacing the parts. become.

By providing a structure in which a commercially available plate-shaped or rod-shaped soft weight (12) can be cut to any length and wrapped around the fishing line threading pipe (7) provided on the fishing line threading lid (3a). A weight for adjusting buoyancy can be placed on the central axis of the fishing float, making it possible to change the buoyancy while keeping the float vertically stable when the fishing float floats on water. In addition, even if the center axis of the float has a pipe for passing the fishing line through, a structure is provided that allows a commercially available soft weight (12) in the form of a plate or rod to be cut to any length and wrapped around it. This provides space for storing weights for adjusting buoyancy.

In the fishing float of the present invention, when the fishing float is floated on the water surface, water reaches the water line (13) of the fishing float inside the through hole (1) provided in the fishing float due to the influence of atmospheric pressure on the water surface. filled with. At this time, the inside of the through hole (1) will be in the same situation as under the water surface with a fishing float floating, and by making the buoyancy adjustment weight (10) stored in the through hole (1) changeable. , only the replacement of the stored weight (10) or the subtracted weight will affect the buoyancy of the fishing float, making it possible to adjust the buoyancy more accurately, and by using a weight of any weight, You can understand the difference in the amount of change in buoyancy between fishing floats. In addition, by providing a center supply/exhaust through hole (6a) at the top of the through hole (1), it can be snapped onto a ring provided below the fishing float and a fishing float that is used by passing a fishing line inside the fishing float. Two types of fishing floats with different ringed floats connected to fishing lines can be used together in one fishing float, thereby eliminating the need to have a plurality of floats having two different structures.

With fishing floats, which are used by passing a fishing line through the interior of the fishing float, it was not possible to change the buoyancy by inserting and removing weights. I solved it by setting

A buoyancy body (15) made of wood, plastic resin, styrene resin, aluminum, or the like is made into a hollow structure to provide buoyancy and is used as a fishing float. A pipe (16) made of plastic resin or metal is passed vertically through the central axis of the fishing float and fixed, and a through hole (1) is provided so that the fishing float has sufficient residual buoyancy but does not touch the water surface. On the other hand, a weight (8) is hermetically housed in the lower part of a buoyancy body (15) of a fishing float so as to float on the water surface with the through hole (1) oriented vertically.

The above-mentioned through hole (1) has an upper end on the water surface side when the fishing float is floated on water, and a lower end on the underwater side in the opposite direction to the water surface, and a lower cover (3) is provided at the bottom of the through hole (1). . The joint between the lower cover (3) and the through hole is provided with a screw thread (2), and has a removable structure that allows it to be removed by turning it in the loosening direction of the screw thread, or to be attached by turning it in the tightening direction of the screw thread. Make it. By making the lower lid (3) removable, a weight for adjusting buoyancy can be stored in the through hole (1) inside the float, and the amount of stored weight can also be changed. The lower lid (3) is provided with a plurality of water supply and drainage through holes (4) for supplying and draining water inside the through hole (1), and a ring is provided at the bottom of the lower lid (3) for holding a float with a tube in a device. (9) is provided to form a lid (3) with a lower ring.

A lid (5) is provided and fixed at the top of the through hole (1). When the fishing float is floated on the water surface, the air inside the through hole (1) is used to supply water from the water supply through hole (4) provided in the lower ring lid (3) by the atmospheric pressure applied to the water surface. A central air supply/exhaust through hole (6a) is provided in the center of the upper lid (5) in order to exhaust air and supply water smoothly into the through hole (1). At least one through hole (6) is provided. In addition, the central supply/exhaust through hole (6a)
(4)
By providing the air through hole (6), when the fishing float is recovered from the water surface or underwater, the water that filled the space in the through hole (1) inside the float can smoothly flow to the water supply and drainage through hole (4) and the air supply and exhaust hole. It is discharged from the hole (6) and the central air supply/exhaust through hole (6a).

The shapes of the water supply/drainage through hole (4), the air supply/exhaust through hole (6), and the center air supply/exhaust through hole (6a) provided in the lower ring lid (3) and the upper lid (5) are as shown in this embodiment. In this case, a round shape is used, but the hole is not limited to a round shape, as long as the hole is large enough to prevent the weight (10) to fall out, and the hole has a mesh pattern to prevent the weight (10) from falling out. A net may be applied.

When the lid (3) with the lower ring is attached to the fishing float body (Fig. 5), the buoyancy of the float can be adjusted by attaching the lid (3) with the lower ring which is connected to the lower part of the through hole (1) by a screw thread. Remove the lid (3) by turning it in the direction of loosening the screw thread, store the weight (10) inside the through hole (1), change the amount and type of the weight (10), and use it for fishing. A structure that allows the buoyancy of the float to be adjusted.

When the above-mentioned through hole (1) is provided in the fishing float body (15), the hole may be drilled directly into the fishing float (15) body and waterproofed. The lower ring lid (3), which has a removable structure for putting in and taking out the adjustment weight, is made of metal, plastic resin, or the like. In addition, the attachment/detachment structure for loading and unloading the buoyancy adjustment weight (10) may be provided on either side of the upper lid (5) or the lower ringed lid (3), or may be provided on both sides. In addition to the screw structure, it is also possible to use a structure using a spring or the like, a one-touch detachment method in which a pin moves in and out, or a detachment method using a magnet.

The weight (10) may be a commonly available weight, and may be elliptical as well as spherical as long as it can fit into the through hole (1). Further, the shape of the fishing float is not limited to the elliptical shape of the embodiment, but may be cylindrical, spherical, Soroban-shaped, rod-shaped, etc.

The lower floating lid (3a) is the same as the lower ringed lid (3), but without the ring (9), it has a through hole in the center of the lower ringed lid (3). A fishing line threading pipe (7) is provided, and the upper end of the fishing line threading pipe (7) is connected to the lower part of the through hole (1) by tightening the lower threading lid (3a) by turning it along the tightening direction of the thread. The length should be such that it reaches the inner surface of the center air supply/exhaust through hole (6a) provided in the upper lid (5) when the hole is opened. As a result, the central supply and exhaust hole (6a), which used to function as a supply and exhaust hole when used as a ringed float, can be used as a pipe opening for passing the fishing line, and the fishing line can be passed through the pipe (7) for passing the fishing line. It can be used as a hole to smoothly pass through.

The screw threads (2) provided on the lower ring attachment lid (3) and the lower insertion lid (3a) have the same thread size, and the lower ring attachment lid (3) and the lower insertion lid (3a) have the same screw thread size. The two types of parts (3a) can be shared at the bottom of the through hole (1) provided in the fishing float body, and by replacing them, one fishing float can be used as a ringed float and a hollow float. Can be changed to floats with different structures.

When the above-mentioned lower lid (3a) is attached to the fishing float body, the buoyancy of the fishing float shown in FIG. 13 can be changed by changing the lower end of the through hole (3a) as shown in FIG. A soft weight (12) in the form of a plate or rod is wound around a fishing line threading pipe (7) provided at the center, and is stored in the through hole (1) of the fishing float as shown in FIG. At this time, in order to prevent the water supply hole (4) from being blocked by the weight (12) wrapped around the pipe (7) through which the fishing line is passed, a weight receiver (11) is provided on the pipe for passing the fishing line. A space is secured between the hole (4) and the wrapped weight (12). Further, the plate-shaped or linear soft weight (12) wound around the fishing line threading pipe (7) is structured so that the mass of the weight can be changed by changing the length and thickness. Also, the plate-shaped or linear soft weight (12) to be wrapped around the fishing line threading pipe (7) does not have to be plate-shaped or rod-shaped, but should be a through-hole larger than the diameter of the pipe (7) through which the fishing line is passed. It is a ring-shaped weight with a center hole, and the pipe (7) through which the fishing line is passed is held through the center hole of the ring-shaped weight, and the mass of the ring-shaped weight or the number of ring-shaped weights can be changed. The structure may be such that

Conventional fishing floats have a buoyancy adjustment weight installed inside the fishing float body to enable buoyancy changes, and a sealed space that stores air and is sealed from the outside world to prevent buoyancy errors due to water intrusion. is needed. Also, fishing floats with a structure in which a sealed space is provided inside the main body and the buoyancy is adjusted by injecting water with a dropper etc. also require sealing processing and parts for sealing, just like the above-mentioned fishing floats. . This required the cost of precision machining and the cost of parts, but the invented fishing float eliminates the need to seal off the space in which the weight for buoyancy adjustment is stored from the outside world, and requires precision machining. Costs and parts costs can be significantly reduced. Also, due to the difference in structure between a tube-equipped float and a threaded float, it was impossible to use both fishing floats together in one fishing float, although the buoyancy can be changed. This has been made possible by providing the through hole (1) with a central air supply and exhaust through hole (6a) for water and air.
