Description

  The present invention relates to a cushion rubber for fishing. More specifically, it is connected between the road line side and the Harris side, so that the impact at the time of catching the fish or catching the fish is reduced, and the cutting of the Harris and the cut of the fish are prevented. It relates to the improvement of the cushion rubber used for fishing.

  As a conventional technology of this kind, generally known cushion rubber for fishing uses a cushion body made of Muku wire made of polyurethane elastomer resin, and these wire diameters and lengths are the types of fish to be fishing, Since it is appropriately selected according to the size, it is processed with various specifications. For example, the wire diameter is 10 to 6,0 mm, and the length is about 150 to 2000 mm. Both ends are passed through a ring of a Sarkhan (metal twisted back) and rounded into a loop, or passed through a ring of a snap that is connected to the ring of a Sarkan, and the tip rounded into a loop is heat welded Adhesive fishing cushion rubber is widely known.

  And the sarcans at both ends are connected between the road line side and the Harris side where the fishhook is hung, and have an appropriate elasticity between both sides to exert a cushioning effect, so that when the fish hits the fishhook, It effectively prevents the breakage of the fish due to the cut off of the fish and the rapid pulling of the fish during fishing.

  The main fishing targets of these fishing cushion rubber fishing rods are integrated with basket fishing that packs and gathers food when fishing large fish that live in the deep sea, and weight that packs food gathered by boats. The fishing cushion rubber of Sao's gimmick used for fishing, such as Hiramasa and Isaki fishing, which inhabit water depths of 50m to 60m, is over 30kg in weight and over 2m in length. The body is 2 to 3 mm thick and corresponds to 30 cm in length, and in the case of a larger one, the body of the cushion body is 5 mm in the deep sea 400-500 m, and a strong fishing cushion rubber is set up. It is used as and raises fishing results.

  However, in the case of the above-described prior art, in order to connect the sarkan to the end portion of the cushion body, the sarkan ring body is rolled up through the tip of the cushion body in a folded loop shape, and the tip is overlapped with the actual length portion of the cushion body. For welding, the welding temperature is appropriately adjusted to a heating temperature of 200 to 400 ° C. according to the thickness of the cushion body, and a pressure is applied to bond the material, so that the composition of the material collapses and loses elasticity and becomes brittle. Therefore, there is a strong demand for the connection between the cushion body and Sulcan by the structure that does not impair the tensile cutting strength of the original polyurethane elastomer because the cutting is concentrated in the vicinity of these loop-shaped welds due to the extreme pulling of the fish. It was. In other words, if cutting occurs between the actual lengths of the cushion body, the aim is to be able to demonstrate the tensile cutting strength inherent to the elastic body of the cushion body and to realize a strong fishing cushion rubber with little damage. It is.

  In addition, depending on the welding temperature adjustment and pressing pressure adjustment, the elongation ratio, tensile strength, hardness, rebound resilience, insufficient adhesion strength, etc. are induced in the vicinity of the bonding part, and various properties as an elastic body of the cushion body are reduced. There are problems such as being forced to replace with new ones due to unevenness in quality, such as the adhesive part peeling off or cracks being unable to withstand the pulling of the fish.
