Description

DETAILED DESCRIPTION OF THE INVENTION Conventional fishing weights have been formed separately for different weights. Therefore, in order to select a weight that is suitable for use, it is necessary to purchase several types of weights of different weights in advance and bring them to the fishing spot, which is not only uneconomical but also portable. It also increases in bulk and becomes quite masochistic. Furthermore, even when selecting a weight with the optimum weight, the weight must be adjusted each time to make the selection, which is cumbersome. Furthermore, in the process of inserting the fishing line into the insertion hole inside the weight,
There is simply a hole drilled inside the weight for the fishing line to pass through, so if you want to replace the weight with a different weight after attaching it to the fishing line, you can do so without cutting the fishing line. If this is not possible, the length of the fishing line will be shortened accordingly, and the effort involved will be troublesome. In the case of biting weights or plate weights, it is not necessary to cut the fishing line as described above when adjusting the weight. Not only is it a hassle to do this, but you also have to adjust the float every time to adjust the weight, which is similar to the case above. This deforms the shape, making it difficult to reuse it, and the water resistance is extremely high.

The present invention divides one weight into several types of weight members, connects these weight members to each other, and makes them separable, thereby making it possible to quickly and easily adjust the weight, and to improve the efficiency of the above-mentioned conventional methods. The purpose of the present invention is to provide a weight for fishing that can solve the various problems that the fishing rod had.

An example of implementing the present invention will be described with reference to the attached drawings.

lFi is a head weight member, which has a receiving ring 2 for attaching a fishing line on the upper part, and a recessed hole 3 bored inward from the bottom part in the lower part. An acid screw is formed on the inner circumferential surface of. Reference numeral 4 denotes a rear weight member, and a protrusion 5 that fits into the recess 3 on the lower surface of the head weight member 1 is integrally formed on the upper surface of the rear weight member. A male thread is formed that screws into the acid thread. Reference numeral 6 denotes an adjustment weight member interposed between the head weight member l and the rear weight member 4, and a projection 7 having a male screw formed on the outer peripheral surface is formed protrudingly on the upper surface, and a projection 7 is formed on the lower surface. , a recessed hole 8 with a screw thread formed on the inner circumferential surface is bored inward from the bottom surface. The protrusion 7 of this adjustment weight member is screwed and fitted into the external thread in the recessed hole 3 of the head weight member 1 or into the external thread in the recessed hole 8 of another adjustment weight member via the external thread on its outer peripheral surface. In addition, the recessed hole 8 of the adjustment weight member is screwed into the male thread of the protrusion 5 of the rear weight member 4 or the male thread of the protrusion 7 of another adjustment weight member via the internal thread on its inner peripheral surface. do. Therefore, when using the head weight member 1, rear weight member 4, and adjustment weight member 6 to form a weight with the optimum weight for use, the head weight member 1 and the rear weight member 4 must be An appropriate number of adjustment weight members 6 are interposed between them, and they are connected to each other by being screwed and metal-molded through the projections and recesses, respectively. By the way, in the fang 1 figure, there are 4 [6] between the head weight member 1 and the rear weight member 4.
This is an example in which an adjustment weight member 6 of 210 is interposed.
Corresponds to the weight of the number. Further, as shown in the spear 2, there is a case where the rear weight member 4 is directly connected to the head weight member 1 without intervening the adjustment weight member 6, and this corresponds to a No. 90 weight.

Figures 1 and 4 and Figure 5 show other embodiments, and show the calibration of the adjustable weight when the weight is a thread-through type weight in which a fishing line is inserted through a hole drilled inside the weight. be. In this adjustment weight member 6', an insertion hole 9 for passing a fishing line is vertically bored in the interior and is connected to the recess 8 from the upper surface of the projection 7. A connecting dividing groove 10 and a dividing groove 11 connecting the insertion hole 9 and the recessed hole 8 are formed from the outer peripheral surface of the main body in which the recessed hole 8 is formed. The grooves 10 and 11 are connected. In addition, when using this thread-through type adjustment weight member 6', although not shown, the head weight member 1 and the rear weight member 4 also have an insertion hole vertically drilled therein for passing the fishing line. Use the one set.

Therefore, the adjustment weight member 6 with such a groove 10.11
’, when adjusting the weight, the percentage #10
．． Since it can be easily removed from the fishing line through the ll'r, there is no need to cut the fishing line one by one even if it is a threaded type.

, 176 and Fang 7 show still other embodiments.
Reference numeral 12 designates a washer-like fine adjustment weight member with a slit, which is conveniently fitted into the protrusion of the adjustment weight member 6, 6' or the protrusion 5 of the rear one-piece member 4.

By using this, it is possible to achieve even more optimal weight adjustment.

It should be noted that each weight member in the above embodiment is made of lead, and there is also a case where the weight member is made of lead and has a threaded part formed in the protrusion and the recessed hole. If the threaded portion is yellowish L7, the thread will not collapse even during long-term use, making it suitable for use. Although the connecting means for each weight member is shown to be screw-fitting, it is not necessarily limited to this, and any suitable means may be used.

As described in the paper, the present invention divides a fishing rod into a head weight member, a rear weight member, and an appropriate number of adjustment weight members interposed in between, and the three types of weight members are Since they can be connected and separated by screwing, etc., by adjusting the number of A-joint weight members interposed between the head weight member and the rear weight member, it is possible to quickly, easily, and reliably find the optimum for use. It is possible to select the weight of the pattern needle, and therefore it is not necessary to purchase several types of weights with different M depths in advance and bring them to the fishing spot, as was the case in the past. It is economical because it can be used in common and only the required number of adjustment weight members interposed between the two can be prepared, and it is relatively small in size even when carried on a mobile device, reducing weight. be able to. Furthermore, since the weight is determined by the number of adjustment weights, there is no need to rely on the cumbersome effort and intuition of adjusting the weight every time to adjust the weight, as in the past. By simply connecting the number of adjustment weights determined by the equation, it is possible to perform the 11th round with ease. Furthermore, unlike chewing weights and plate weights, it does not deform after use or have large water resistance, making it suitable for use.
