Abstract

Official abstract text for this publication.

One object is to provide a jig head including a sinker head and a hook readily replaceable with new one. A jig head includes: a sinker head including an eye to which a fishing line is to be attached; and a hook portion including a shank fixed on the sinker head at one end thereof, and a bend continuous to the other end of the shank and bent in a predetermined direction. The hook portion includes a wide portion widened to form a plane at the one end of the shank. The sinker head includes: an intermediate member having a hook engagement portion configured to be removably engaged with the wide portion; an intermediate member-receiving hole portion configured to receive therein the intermediate member; and an intermediate member-fixing means configured to removably fix the intermediate member in the intermediate member-receiving hole portion.

First claim

Opening claim text (preview).

What is claimed is: 1. A jig head comprising: a sinker head including an eye to which a fishing line is to be attached; and a hook portion being fixed to the sinker head, the hook portion comprising a shank and a bend, the shank having a first end and a second end, the first end including a wide portion that is widened to form a plane thereat and the second end being continuous into the bend of the hook portion, the bend being bent in a predetermined direction; wherein the sinker head further comprises an intermediate member and an intermediate member-receiving hole portion, the intermediate member having a hook engagement portion that surrounds the wide portion of the first end of the shank; the intermediate member further comprising a tapered surface that narrows towards the bend in the shank of the hook portion; the intermediate member-receiving hole portion comprising a tapered through hole, the tapered through hole having a first end and a second end, the tapered through hole extending along a width of the sinker head and tapering from the first end to the second end in a longitudinal direction such that the second end is narrower than the first end, and both of the first end and the second end opening to an outer peripheral surface of the sinker head; wherein the tapered through hole receives the tapered surface of the intermediate member therein such that the tapered surface is engaged with a surface of the tapered through hole, and wherein the intermediate member comprises a crimped surface at an end of the tapered surface of the intermediate member, the crimped surface fixing the intermediate member in the intermediate member-receiving hole portion, and the crimped surface being provided at the first end of the tapered through hole of the intermediate member-receiving hole portion. 2. The jig head of claim 1 , wherein the wide portion is constituted by a ring formed of a bent end of the hook portion opposite to a point, and the hook engagement portion has a groove shape to be engaged with the ring. 3. The jig head of claim 1 , wherein the crimped surface of the intermediate member extends over the first end of the tapered through hole of the sinker head. 4. The jig head of claim 1 , wherein the tapered surface and the tapered through hole have the same angle of inclination. 5. The jig head of claim 1 , wherein the intermediate member comprises two halves that engage with the wide portion. 6. The jig head of claim 5 , wherein the intermediate member has linear grooves into which at least part of the shank is inserted. 7. The jig head of claim 6 , wherein the wide portion comprises a ring, and wherein the hook engagement portion has a groove-like shape for receipt of the ring therein. 8. The jig head of claim 5 , wherein the wide portion comprises a ring, and wherein the hook engagement portion has a groove for receipt of the ring. 9. The jig head of claim 1 , wherein the hook engagement portion has a complimentary groove for the wide portion. 10. A method of forming a jig head, the jig head comprising: a sinker head including an eye to which a fishing line is to be attached and a tapered through hole extending along a width of the sinker head, the tapered through hole having a first end and a second end each opening to an outer peripheral surface of the sinker head and tapering from the first end to the second end in a longitudinal direction such that the second end is narrower than the first end; a hook portion comprising a shank and a bend, the shank having a first end and a second end, the second end of the shank being connected to a bend of the hook portion, the bend being bent in a predetermined direction; and an intermediate member having a hook engagement portion that surrounds a portion of the first end of the shank and a tapered surface; and the method comprising: engaging the first end of the shank of the hook portion with the hook engagement portion of the intermediate member such that the tapered surface of the intermediate member is positioned to narrow towards the bend of the hook portion; inserting the tapered surface of the intermediate member into the tapered through hole of the sinker head; driving the intermediate member into the tapered through hole of the sinker head; and forming a crimped surface on an end of the intermediate member to fix the intermediate member in the tapered through hole, the crimped surface being provided at the first end of the tapered through hole, and the hook portion extending through the second end of the tapered through hole. 11. The method according to claim 10 , wherein the first end of the shank of the hook portion includes a wide portion that is widened to form a plane therat, and wherein the engaging of the first end of the shank comprises surrounding the wide portion of the first end of the shank with the hook engagement portion of the intermediate member. 12. The method according to claim 11 , wherein the wide portion at the first end of the shank has a ring, and wherein the hook engagement portion has a groove shape to be engaged with the ring, and wherein the engaging of the first end of the shank comprises inserting the ring into the groove shape. 13. The method according to claim 11 , wherein the intermediate member comprises two halves with opposing surfaces that are configured to enclose the wide portion of the shank, and wherein the engaging of the first end of the shank comprises enclosing the opposing surface of the two halves together to engage the wide portion. 14. The method according to claim 10 , wherein the hook engagement portion has a groove therein that is complimentary to a shape of the first end of the shank of the hook portion, and wherein the engaging of the first end of the shank comprises inserting the shank into the groove of the hook engagement portion.
