The technique published in Patent Document 1 described above provides a waterproof function inside the fishing float to provide a closed space, and adjusts the volume of air inside the fishing float by changing the volume in the space. It enables the buoyancy of the fishing float body to be adjusted. By changing the buoyancy of the fishing float, it is possible to change the fishing method and mechanism according to various situations, and it is popular with many users, but the above-mentioned fishing float is as follows. There is a problem as described in.

The above-mentioned fishing float has a structure that allows the buoyancy of the fishing float body to be changed by adjusting the volume of air inside, but the buoyancy is adjusted by adjusting the invisible amount of air. There is a problem that it is difficult to grasp the amount of change in buoyancy given to the fishing float because it has been changed. In addition, there is a space inside the fishing float that can be sealed to prevent water from entering, and weights are stored in that space, and the number of stored weights can be changed, and the size and mass can be changed for fishing. There is also a fishing float with a structure that allows you to change the buoyancy of the float. However, if the size of the stored weight is changed or the number of weights is changed, the total volume of the stored weights will change, so the air volume of the space where the weights are stored will change, resulting in accurate floating. It is difficult to grasp the amount of change in buoyancy.

The technique published in Patent Document 2 described above means that when a fishing float is floated on the water surface of the fishing float body, the fishing float is placed on the water surface in a space for accommodating a weight for adjusting the buoyancy provided on the floating fishing float. It has been proposed that a structure that fills water with atmospheric pressure is provided, and that only the replacement of the stored weight and the weight of the subtracted weight affect the buoyancy of the fishing float, so that the exact change in the buoyancy of the fishing float can be grasped. Has the following issues.

The above-mentioned fishing float has no space for storing the weight for adjusting the buoyancy on the vertical center line of the center of gravity where the fishing float floats vertically and stably when the fishing float is floated on the water surface. It is conceivable that the mass of the weight that can adjust the buoyancy within the range where the fishing float that floats on the float can maintain the vertical posture is extremely small, and the range of buoyancy change is also reduced. Further, since the water injection hole provided for filling the space for storing the weight for buoyancy adjustment is arranged at the upper part of the float, the space for storing the weight for adjusting buoyancy cannot be smoothly filled with water. There's a problem.

There are many types of fishing floats that are open to the public, such as hollow floats or floats with rings. These fishing floats have a constant buoyancy and are made stable, and are trusted and well received by users, but they have the following problems.

The above-mentioned hollow float through which the fishing thread passes inside the fishing float and the ringed float used by connecting the fishing float to the fishing thread by snapping to the ring provided at the bottom of the fishing float are classified into two types due to their structure. Due to structural differences, one fishing float cannot be used in combination with the above two types of fishing floats. In addition, the buoyancy-changeable fishing float has a structure that allows weights to be taken in and out of the space by providing a sealed space inside with a hollow float, because it has a pipe for passing fishing line in the center of the float. In addition, a commercially available round weight or the like cannot be stored in the center of the float and is biased to one side, and when the float is floated on the water surface, it may be tilted. Further, since the pipe for passing the fishing line is provided in the center of the float, it is not possible to provide a space for storing the weight. Therefore, in the case of a hollow float, a fishing float whose buoyancy can be changed by putting a weight in and out of the float has not been put into practical use yet.

The present invention has a through hole (1) on the central axis of the fishing float, and when the fishing float having the through hole (1) is floated on the water surface, the fishing float floated by the atmospheric pressure applied to the water surface. A structure filled with water is provided inside the through hole (1). The water surface of the fishing float (13) 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 adjusting the buoyancy can be held or taken out in the through hole (1) filled with water to change the weight of the weight.

A mechanism for supplying and draining water to and from the inside of the through hole (1) is provided on the central axis of the fishing float, and by using this mechanism, a fishing float used by passing a fishing thread through a pipe held inside the fishing float can be used. Two types of floats with different structures, which have a ring (9) at the bottom of the fishing float to hold the float as a device, can be used together by simply exchanging parts with one fishing float. become.

By providing a structure in which a commercially available plate-shaped or rod-shaped soft weight (12) can be cut to an arbitrary length and wound around the fishing line threading pipe (7) provided on the center-through floating lid (3a). , A weight for adjusting buoyancy can be placed on the central axis of the fishing float, and when the fishing float is floated on water, the floating posture remains vertically stable and the buoyancy can be changed. Further, even if a pipe for passing a fishing line is provided on the central axis of the float, a structure is provided in which a commercially available plate-shaped or rod-shaped soft weight (12) can be cut to an arbitrary length and wound. Therefore, it has a space for storing a weight for adjusting buoyancy.

The fishing float of the present invention has water up to the waterline (13) of the fishing float inside the through hole (1) provided in the fishing float due to the influence of the atmospheric pressure applied to the water surface when the fishing float is floated on the water surface. Filled with. At this time, the inside of the through hole (1) becomes the same as under the water surface with a floating fishing float, and the buoyancy adjustment weight (10) stored in the through hole (1) can be changed. , Only the replacement of the stored weight (10) and the weight of the subtracted weight will affect the buoyancy of the fishing float, and more accurate buoyancy adjustment will be possible. The difference in the amount of change in buoyancy of the fishing float can be grasped. Further, by providing the central air supply / exhaust through hole (6a) above the through hole (1), the fishing float is used by passing the fishing thread through the inside of the fishing float, and the fishing float is snapped to the ring provided below the fishing float. Since two types of fishing floats with rings and different types of floats used by being connected to a fishing thread can be used together with one fishing float, it is not necessary to have a plurality of floats having two different structures.

The fishing float, which is used by passing fishing line inside the fishing float, could not have the function of changing the buoyancy by putting the weight in and out, but it has a structure in which a soft weight (12) in the shape of a plate or a rod is wrapped around and stored. Was set up and solved.

By providing the air through hole (6), when the fishing float is recovered from the water surface or water, the water filled in the through hole (1) space inside the float can be smoothly passed through the water supply / drainage through hole (4) and the air supply / exhaust. It is discharged from the hole (6) and the central air supply / exhaust through hole (6a).

The shapes of the water supply / drainage through holes (4), the air supply / exhaust through holes (6), and the central air supply / exhaust through holes (6a) provided in the lower ring-attached lid (3) and the upper lid (5) are the shapes of the present embodiment. The round shape is adopted, but it is not limited to the round shape, as long as the hole has a size that prevents the weight (10) to be stored from falling off, and the hole has a mesh shape to prevent the weight (10) from falling off. You may give a net.

When the lid (3) with a lower ring is attached to the fishing float body (FIG. 5), the float buoyancy change adjustment is performed with the lower ring connected to the lower part of the through hole (1) by a screw thread. Remove the lid (3) by turning it along the loosening direction of the screw thread, store the weight (10) inside the through hole (1), and change the amount and type of the weight (10) for fishing. A structure that can adjust the floating force of the float.

When the above-mentioned through hole (1) is provided in the fishing float body (15), the hole may be directly processed and waterproofed in the fishing float (15) body, and the through hole (1) has buoyancy. The lower ring-attached lid (3) having a detachable structure for putting in and taking out the adjustment weight is formed of metal, plastic resin, or the like. Further, the attachment / detachment structure when the weight for adjusting the buoyancy (10) is taken in and out may be provided on either side of the upper lid (5) or the lower ring-attached lid (3), or may be provided on both sides. In addition to the screw structure, a structure using a spring or the like, a one-touch attachment / detachment method in which a pin goes in and out, or a attachment / detachment method using a magnet or the like is also possible.

The weight (10) may be a generally sold one, and may be not limited to a spherical shape but may have an elliptical shape as long as it fits in the through hole (1). Further, the shape of the fishing float may be not only the elliptical shape of the embodiment but also a cylindrical shape, a spherical shape, an abacus type, a rod shape, or the like.

The lower center-through floating lid (3a) is the same as the lower ring-attached lid (3), but does not have a ring (9), and has a through hole in the center of the lower ring-attached lid (3). A fishing line pipe (7) is provided, and the upper end of the fishing line threading pipe (7) is joined by turning the lower centering lid (3a) under the through hole (1) along the tightening direction of the thread and tightening. At that time, the length is set to reach the inner surface of the central air supply / exhaust through hole (6a) provided in the upper lid (5). As a result, the central air supply / exhaust through hole (6a), which played the role of an air supply / exhaust hole when used as a float with a ring, can be used as a pipe port for passing the fishing line, and the fishing line can be passed through the fishing line pipe (7). It can be used as a hole for smooth passage through the inside.

The screw thread (2) provided on the lower ring-attached lid (3) and the lower through-hole lid (3a) has the same thread size, and the lower ring-attached lid (3) and the lower through-hole lid (3a) have the same thread size. The two types of parts (3a) can be shared with respect to the lower part of the through hole (1) provided in the fishing float body, and by exchanging, one fishing float can be replaced with a ring float and a through-hole float. Can be changed to a float with a different structure.

When the lower through-hole lid (3a) is attached to the fishing float body, the change in the buoyancy of the fishing float in FIG. A plate-shaped or rod-shaped soft weight (12) is wound around a fishing line threading pipe (7) provided at the center, and is stored in a fishing float through hole (1) as shown in FIG. At this time, in order to prevent the water supply through hole (4) from being blocked by the weight (12) wound around the fishing line threading pipe (7), a weight receiver (11) is provided on the fishing line threading pipe to penetrate the water supply. A space is secured between the hole (4) and the wound weight (12). Further, the plate-shaped or linear soft weight (12) wound around the fishing line threading pipe (7) has a structure in which the mass of the weight can be changed by changing the length and thickness. Further, the plate-shaped or linear soft weight (12) wound around the fishing line threading pipe (7) has a through hole larger than the diameter of the pipe (7) through which the fishing line is passed, even if it is not plate-shaped or rod-shaped. With a ring-shaped weight centered on the fishing line, 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 is changed or the number of ring-shaped weights is changed. It may be a structure that does.

The conventional fishing float is a buoyancy adjustment weight provided inside the fishing float body to allow the buoyancy to be changed. Is needed. In addition, a float having a structure in which a sealed space is provided in the fishing float body and water is injected with a dropper or the like to adjust the buoyancy also requires parts for sealing and sealing as in the fishing float described above. .. For this reason, the cost of precision processing and the cost of parts were incurred, but the fishing float invented does not require the space for storing the weight for adjusting buoyancy to be sealed from the outside world, and for precision processing for that purpose. The cost and parts cost can be greatly reduced. In addition, it was not possible to use both fishing floats in a single fishing float in the fishing floats that allow the buoyancy to be changed due to the difference in the structure of the floating floats with pipes and the floating floats. Was made possible by providing a central air supply / exhaust through hole (6a) for water or air in the through hole (1).
