TECHNICAL FIELD

The present disclosure relates to multipurpose pliers, and more particularly, to multipurpose pliers for a fishing line.

BACKGROUND ART

Pliers are a hand tool used to hold objects firmly, possibly developed from tongs used to handle hot metal in Bronze Age Europe.

The pliers are used for bending, compressing or cutting objects made from a wide range of materials, and they consist of a pair of lever sections on one side of a pivot and a pair of handle sections on the other side, allowing a force applied to the handle to move the lever sections around the pivot.

The force acts on the lever sections and the handle across the pivot which serves as a fulcrum.

The present disclosure relates to pliers into which many functions required in preparation for fishing with traditional pliers are integrated, but the present disclosure is not limited to fishing and may be used in a wide range of fields.

In preparation for fishing, various functions are needed, for example, a function of cutting a fishing line such as, for example, a polyethylene line (fishing line), a carbon line and a nylon line, or cutting a wire and a line including a wire, and a function of attaching a fishing bait and a fishing hook to a split ring, and the present disclosure relates to pliers having these various functions.

Fishing pliers such as the present disclosure are disclosed in Utility Model Registration Nos. 20-0202732 and 20-0296965, but the related arts do not describe a distortion prevention function and a function for split rings.

BEST MODE

FIG. 1is a top view of multipurpose pliers of the present disclosure.

The multipurpose pliers of the present disclosure includes a lever section10on one side of a pivot section20and a handle30on the other side.

As a pair of handle sections30A and30B is opened or closed by an applied force, the lever section10is opened or closed with respect to the pivot section20, and various functions of the lever section are performed.

As shown inFIG. 1, the lever section10includes a split ring insertion part11, a concave-convex part12, a distortion prevention part13, a line cutter part14, a wire cutter part15, and a distortion prevention part16to provide various functions, and a grease supply part40is provided on the side surface of the pivot section20, and the handle section30is provided with an additional distortion prevention part31, and each function is described as follows.

As shown inFIG. 3, the multipurpose pliers of the present disclosure includes a first body100A including a first lever section10A, a first pivot section20A, and a first handle section30A, and a second body100B including a second lever section10B, a second pivot section20B, and a second handle section30B, a first pivot member20D is inserted into a first hole20Aa of the first pivot section20A and a second pivot member20C is inserted into a second hole20Bb of the second pivot section20B, and a cylindrical protrusion20Dd of the first pivot member20D is inserted into and engaged with a hole20Cc of the second pivot member20C.

FIG. 4is an enlarged perspective view of the pair of first and second pivot members20C and20D, the first pivot member20D has a circular plate head20Da and the protrusion20Db with a cylindrical shape protruding at the center of the circular plate head, and the second pivot member20C has a circular plate head20Ca, a protrusion20Cb having a cross section with a circular shape truncated on both sides formed at the center of the circular plate head20Ca, and the hole20Cc with a circular shape at the center of the protrusion20Cb.

Referring toFIGS. 3 and 4, the second hole20Bb of the second pivot section20B also has the same cross section as the cross section of the protrusion20Cb shown inFIG. 4, i.e., a cross section with a circular shape truncated on both sides, and when the second pivot member20C is inserted into the second hole20Bb of the second pivot section20B, the second body100B cannot rotate around the second pivot member20C due to the cross sectional shape.

By contrast, the first hole20Aa of the first pivot section20A has the same circular cross section as the cross section of the protrusion20Db shown inFIG. 4, and when the first pivot member20D is inserted into the first hole20Aa of the first pivot section20A, the first body100A can rotate around the first pivot member20D because the cross section is circular in shape.

When the cylindrical protrusion20Db of the first pivot member20D is inserted into the circular hole20Cd of the second pivot member20C and assembly is completed as shown inFIG. 5, the second body100B cannot rotate around the pivot section20and only the first body100A can rotate around the pivot section20.

The pliers such as the present disclosure are subjected to a twisting force (moment) while in use, but the present disclosure allows only one100B of the pair of bodies100A and100B to move around the pivot section20and disallows the other100A to move around the pivot section20, rather than allowing all the pair of bodies100A and100B to move respectively, thereby reducing the degree of freedom of the pliers themselves and resisting the twisting force more efficiently.

The split ring insertion part11is formed at the end of the lever section10in a direction facing away from the pivot section20, and has a protruding shape on one10A of the pair of lever sections10, protruding in a direction perpendicular to the longitudinal axis direction (L) of the multipurpose pliers, and a portion accommodating the protruding shape on the other10B of the lever sections10.

Describing the split ring insertion part11in more detail throughFIG. 6a, the split ring insertion part11includes a tapered portion11A gradually narrowing to a tip at the end of one10A of the lever sections10, a bottom support portion11B having a cross section larger than or equal to a cross section of a bottom surface of the tapered portion11A, a convex forming portion11C on side surfaces of the tapered portion11A and the bottom support portion11B, a concave forming portion11D accommodating the convex forming portion11C at the end of the other10B of the lever sections10, and a split ring retaining portion11E to retain the location of a split ring200on the side direction of the concave forming portion11D.

The length of the other10B of the pair of lever sections10is shorter than the length of one10A of the lever sections having the bottom support portion11B by the width of the bottom support portion11B.

It can be seen fromFIGS. 6bthrough 6d that when the lever sections are closed, the convex forming portion11C of one10A of the lever sections10is closed along the concave forming portion11D of the other10B of the lever sections10.

Accordingly, the convex forming portion11C of one10A of the lever sections10and the concave forming portion11D of the other10B of the lever sections10act as guide rails.

Preferably, the cross section of the tapered portion11A and the cross section of the bottom support portion11B are discontinuous.

The tapered portion11A has a pointed shape to allow for easy insertion into a gap210between rings of the split ring200wound in circular shape as shown in FIG.7a.

When the pointed tip of the tapered portion11A is inserted into the gap210between the rings of the split ring wound as shown inFIG. 7a, and subsequently, a part of the bottom support portion11B is inserted into the split ring and the gap210between the rings of the split ring is widened, a ring310connected to an artificial bait300is inserted into the gap between the rings as shown inFIG. 7b.

After the ring310of the artificial bait300is inserted into the gap210between the rings of the split ring200as shown inFIG. 7b, when the ring310moves along the gap210as shown inFIG. 7c, the ring310of the artificial bait300will be connected to the split ring200.

As described above, in the present disclosure, the split ring insertion part11protrudes in pointed shape in the direction perpendicular to the longitudinal axis direction (L) of the multipurpose pliers, so it can connect the ring310of the artificial bait300to the split ring200.

The split ring insertion part11of the present disclosure may be preferably used in opening a split ring having an inner diameter of 3 mm-12 mm.

Referring toFIGS. 10band 10c, while opening up the rings of the split ring200by inserting the tapered portion11A of the split ring insertion part11into the gap210between the rings, in order to retain the location of the split ring200, the split ring retaining portion11E is formed in the shape of a groove on both side directions from the concave forming portion11D.

The split ring retaining portion11E is suitable for small size split rings, for example, having an inner diameter of 3 mm and the split ring retaining portion11E may be used for larger size split rings. A gap in such split rings may be opened by the tapered portion11A when the split rings are disposed on the split ring retaining portion11E as shownFIG. 7c.

The tapered portion11A of the split ring insertion part11may include various types, for example, a conical shape, a triangular pyramid shape, and a quadrangular pyramid shape, and likewise, the bottom support portion11B may include various types, for example, a conical shape, a triangular pyramid shape, and a quadrangular pyramid shape.

Also, the split ring insertion part11of the present disclosure may be used to connect artificial baits as well as rings connected to fishing hooks and rings for other purposes. For example, the split ring insertion part11of the present disclosure may be used for split rings connected to key rings as well.

Although the above description illustrates that the split ring insertion part11has a shape protruding in the direction perpendicular to the longitudinal axis (L-axis), the pliers to which the present disclosure is applied can be used with the split ring insertion part11formed in the direction parallel to the longitudinal axis (L-axis) as well as the split ring insertion part11formed in the direction perpendicular to the longitudinal axis (L-axis), and the pliers can be also used with the split ring insertion part11formed in other shapes.

Also, the multipurpose pliers100of the present disclosure are provided with the concave-convex part12adjacent to the split ring insertion part (11) at a direction toward the pivot section, and the concave-convex part12has a plurality of concave and convex patterns to grasp hooks, split rings, and the like, without slipping.

Also, the distortion prevention part13is provided at a location close to the pivot section from the concave-convex part12. The distortion prevention part13includes a pin13A protruding in the direction perpendicular to the longitudinal axis (L-axis) formed on one10A of the pair of lever sections10, and an accommodating hole formed on the other10B of the lever sections to accommodate the pin13A (seeFIG. 1).

When the split ring accommodating part11is inserted into the gap210between the rings of the split ring, a twisting force is applied to the multipurpose pliers, causing distortion to the multipurpose pliers, and the protruding pin13A of the distortion prevention part13offsets the twisting force when inserted into the accommodating hole. The twisting force may occur from the split ring insertion part11and may also occur during cutting by the line cutter part14and the wire cutter part15.

Also, the present disclosure is provided with the distortion prevention parts16and31adjacent to the pivot section20at the side of the lever section10and the handle section30as shown inFIG. 8.

The distortion prevention parts16and31are formed such that a pair of partial circular plates16A and16B, and31A and31B support each other and exert a force on each other to offset the twisting force applied to the multipurpose pliers.

Referring to the exploded view ofFIG. 2, the pair of partial circular plates16A and16B and31A and31B of the distortion prevention parts16and31are respectively formed on the side surfaces of the first and second pivot sections20A and20B of the bodies100A and100B.

The pair of partial circular plates16A and16B and31A and31B ofFIG. 2are assembled to form the distortion prevention parts16and31with a shape shown inFIG. 8.

As described above, the present disclosure improves the life of products by installing the distortion prevention parts13,16, and31to resist the twisting force applied to the pivot section20of traditional multipurpose pliers.

Also, the line cutter part14and the wire cutter part15are provided adjacent to the distortion prevention part13of the lever section10in a direction toward the pivot section20.

The line cutter part14has a function of cutting a fishing line, for example, a polyethylene line, a carbon line and a nylon line, and the wire cutter part15has a function of cutting a high hardness material such as a wire or a line including a wire.

The wire cutter part15has a plurality of grooves to prevent slips that may occur during cutting because of high hardness of a wire or a line including a wire which needs to be cut by the wire cutter part15, and the wire and the line including the wire is cut when held in the grooves.

Also, referring toFIG. 2, the wire cutter part15, the line cutter part14, the concave-convex part12, and the split ring insertion part11can be assembled and dissembled via screw coupling accomplished by holes for bolts15C,14C and12C and threaded holes15D,14D, and12D. In the case where the cutter part, the part having the groove, and the tapered portion of the split ring insertion part11become blunt while in use, it is possible to replace only the corresponding part with ease.

FIG. 9shows the bottom surface of the pair of lever sections10A and10B into which the split ring insertion part11and the concave-convex part12integrally formed for each of the pair of lever sections10A and10B are inserted and assembled,FIG. 10ashows that the tapered portion11A, the bottom support portion11B, and the convex forming portion11C are integrally formed with the concave-convex part12which are then assembled into the bottom surface ofFIG. 9, andFIG. 10cshows that the concave forming portion11D, and the split ring retaining portion11E are formed integrally with the concave-convex part12which are then assembled into the bottom surface of the pair of lever sections10A and10B ofFIG. 9.

The bolt hole12C of each arrangement ofFIGS. 10aand 10band the bolt hole12D ofFIG. 9are overlapped and bolt-connected to each other, and this is the same case with the bolt holes12C and12D ofFIG. 2.

Each arrangement ofFIGS. 10aand 10bhas four guide grooves12F, and the arrangement ofFIG. 9has guide protrusions12E which are inserted into the guide holes12F, thereby preventing sway during assembly.

Although the above description illustrates that the pair of split ring retaining portions11E and concave-convex parts12integrally formed have the guide grooves12F formed on the bottom surface and are assembled into the pair of lever sections10A and10B, besides the split ring retaining portions and the concave-convex parts, a tool tip useful for performing other functions may be installed and used in at least one of the pair of lever sections10A and10B, and the tool tip also has guide grooves12F to prevent sway by inserting the guide protrusions12E into the guide grooves12F of the tool tip when the tool tip is engaged with the bottom surface of at least one of the pair of lever sections.

Also, the present disclosure has a grease insertion port installed on the side surface of the pivot section20to supply greases to the multipurpose pliers of the present disclosure through the grease insertion port.

Also, to reduce the total weight, the present disclosure has a plurality of through-holes32in the handle sections, and the handle is in such a shape that they have concave and convex curves to prevent slips while in use.

Also, the handle section30is further provided with a fishing hook adjustment part33to correct an angle of a warped fishing hook.FIG. 11is an enlarged view of the fishing hook adjustment part33, and a warped fishing hook is inserted into the adjustment part33and is then adjusted as shown inFIG. 12.
