Description

[Detailed description of the invention] This invention relates to a rolling swivel for use in fishing, particularly a rolling swivel for use with hollow weights.

As is well known, a rolling swivel is a device in which a plurality of thread rings are rotatably connected by a connecting rod and a weight is fixed. A conventional rolling swivel of this type has a weight A as shown in Fig. 1.
There is a structure in which a short thread ring 4 is rotatably supported by a connecting rod 2 whose one end side is embedded and fixed in the upper and lower ends of the connecting rod 2, respectively. However, in the case of this conventional example, when replacing the weight A, each thread ring 4 and thread C
It has the disadvantage that it takes time and effort to reconnect each time. To correct this drawback, there is a rolling swivel as shown in FIG. In this conventional example, one long thin thread ring 3 rotatably supported on a connecting rod 2 is passed through the center hole B of the weight A, and a fastening snap D is inserted into the connecting hole 8 at the tip of this long thin thread ring 3. It is used by tying the thread C and then tying the thread C to the other short thread ring 4 which is rotatably supported on the connecting rod 2. In this conventional example, the lower end of the weight A is prevented from moving downward by the connecting rod 2, and the upper end of the weight A is prevented from moving upward by the stopper snap D. Accordingly, the weight A can be attached to a predetermined position. Unlike the previous conventional example, when removing the weight A, it is possible to remove the stopper snap D from the long thin thread ring 3 and then pull out the weight A from above the long thin thread ring 3. , untie the thread C,
This has the advantage that the weight A can be replaced without cutting the thread C.

However, in this conventional example,
During fishing, the lower end of the weight A constantly collides with the upper end of the connecting rod 2, so that the lower open end of the center hole B of the weight A gradually deforms and wears out as shown in FIG. As the number of uses increases,
This has the disadvantage that the long thin thread ring 3 cannot be passed through the center hole B of the weight A. This is because the material of weight A is lead, which is a soft metal, and the material of one connecting rod 2 is a harder metal such as brass, but as a result, weight A cannot be replaced. There were technical issues.

This invention was made to solve this technical problem, and its technical feature is that by interposing a buffer member between the weight and the connecting rod, it can be used while fishing. This is where the weight and connecting rod are prevented from colliding.

Examples of this invention will be described below based on the drawings.

The rolling swivel 1 of this invention has a connecting rod 2
In a rolling swivel in which a long thread ring 3 and a short thread ring 4 are rotatably connected to both ends of the rolling swivel, a locking part 5 is attached to the end of the long thread ring 3 on the connecting rod 2 side at a predetermined distance from the connecting rod 2. A buffer member 6 is provided, and the center of the locking portion 5 is supported by the long thin thread ring 3.
This is a lock.

The locking portion 5 provided on the thin thread ring 3 may be formed by spreading the thin thread ring 3 outward to form a small circular protrusion as shown in Fig. 5, or may be formed by spreading the thin thread ring 3 outward to form an orthogonal protrusion perpendicular to the thin thread ring 3 as shown in Fig. 7, or may be a member separate from the thin thread ring 3 fixed to the thin thread ring 3. The reason for providing this locking portion 5 at the end of the thin thread ring 3 on the connecting rod 2 side at a predetermined distance from the connecting rod 2 is that if the locking portion 5 and the connecting rod 2 are in close contact or too close, the buffer member 6 locked to the locking portion 5 will come into contact with the connecting rod 2 during use, causing poor rotation of the thin thread ring 3 relative to the connecting rod 2.

The buffer member 6 is a spherical member made of a flexible material such as synthetic resin with a through hole 7 formed in the center, and when in use, the long thin thread ring 3 is passed through the central through hole 7, and the long thin thread ring is The locking portion 5 formed in 3 is used to lock the device to prevent it from falling. In the embodiment shown in FIGS. 4 and 5, locking is achieved by fitting and inserting the locking part 5 into the through hole 7 of the buffer member 6, and the embodiment shown in FIGS. In this example, the lower end of the buffer member 6 is locked by the locking portion 5 to prevent it from falling.

When using the rolling swivel 1 of this invention constructed as described above, as shown in FIG. The center hole B of the weight A is inserted into the long and thin thread ring 3, and then the fastening snap D with the thread C tied to it is fitted into the connecting hole 8 at the tip of the long and thin thread ring 3 for connection. The thread C is directly tied to the connecting hole 9 of the short thread ring 4 as before, but it may also be used by connecting it with another fastening snap or by connecting it with another tool. Of course.

When replacing the weight A, remove the stopper snap D from the connecting hole 8 of the long thin thread ring 3, and then
Pull out the weight A from the long thin thread ring 3, then insert the long thin thread ring 3 into the center hole B of another weight, and attach the stopper snap D with the thread C tied to the connecting hole 8 of the long thin thread ring 3 again. Just fit it in and connect it.

As is clear from the above description, the rolling swivel 1 of this invention has a locking portion 5 on the long thin thread ring 3.
A buffer member 6 is fixed to this locking portion 5 so that the lower end of the weight A collides with the buffer member 6 made of a flexible material and does not directly collide with the connecting rod 2. Because of this, unlike conventional rolling swivels, it is possible to prevent the lower opening end of the center hole B of weight A from deforming and the opening becoming smaller, so there is no problem in replacing weight A. . Furthermore, since a predetermined distance is provided between the locking part 5 and the connecting rod 2, the buffer member 6 does not come into contact with the connecting rod 2, so that the rotation of the long thin thread ring 3 with respect to the connecting rod 2 is smooth. There are particular advantages of this invention carried out.
