Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weight used in fishing to keep the hook of a fishing line below the surface of the water. Such weights are commonly referred to as sinkers.

Sinkers have been used for many years and have been made in many shapes to suit various usage situations. When anglers use a fishing line with a weight attached to a rocky shoreline or near a reef, there is a risk that the weight may get caught on a rock, making it difficult to remove it. was always there. The present invention aims to substantially solve this problem.

The present invention has a longitudinally uniformly tapered elongated pentahedral body with a similar isosceles triangular base that is larger than the isosceles apex, and the base and the apex are in contact with the bottom of the body. The edge connecting the vertices of the triangle forming the top is in a parallel plane perpendicular to the top edge of the main body, is parallel to the top edge of the main body, and the main body forms a bottom and a top at both ends. A weight having an arm extending from the top of the body in a direction parallel to the tA bar disposed in the central longitudinal direction on the base surface of the body, which is a surface having a triangular base, and the horizontal bar. This is what we provide.

Particular embodiments of the invention will now be described with reference to the accompanying drawings.

The sinker is a pentahedral body with a triangular cross section, and this triangle is an isosceles triangle. This body has a base surface l and λ adjacent surfaces 2 and 3 of the same size. The body further has λ end sections and j, each of which is in the shape of an isosceles triangle, one end being larger than the other end. The ends ≠ and j are parallel and the body is located in a plane perpendicular to the plane occupied by the base edge B of the body from end to end.

Teno's arm is evenly applied.

A crossbar 7 is arranged in the central longitudinal direction on the base l of the body, which has a leg r that is embedded in the base l. Horizontal bar 7
is parallel to the top edge t of the body.

It will be seen from the figures that the leg trestles (as shown by the dashed outline) have a special shape after they are embedded in the body. The leg l has a tail 10 passing through the body and aligned with the extension ii of the leg. The tail 10 can also be placed on the top edge 6, and a wear strip along the edge 6 can be provided if desired. The extension (arm) ll projects substantially centrally from the end of the body and is located parallel to the crossbar 7. The cross bar 7 and its extensions 1 to 11 are preferably made of a hard, corrosion-resistant material, such as stainless steel bar. The tail io need not be part of the crossbar leg t.

The shape of the main body was developed as a result of extensive experimentation, and it is still desirable that the angular relationships of its various surfaces be as follows.

The included angle between the top edge 6 and the base l of the main body is preferably /j', but may be in the range of io"i to 200.

Although it is desirable that there be an included angle of 200 between the long side /J of the base l and 13, this angle may be between 77° and 250. The end of the main body ≠ and! is preferably j-2
, is an isosceles triangle with a base angle of 0 and an apex angle of 7!0. These angles vary with the apex angle ranging from 65' to ff J'' and correspondingly the base angle being determined from ≠j, j0 to 17.j'.

An average size weight made of lead and weighed in grams, yet having the desirable characteristics detailed above, is 3! The length of the main body from one end to the other is λ01al+, and the maximum base width is λ01al+. The extension part is 3 h from the end of the main body.
The diameter of the horizontal bar and its extension is 2mm, the length of the horizontal bar is 2mm, and the legs t and 2 are equidistant from the ends ≠ and j of the body.

The operation of the main unit will be explained below with reference to Figures 1-1J. Figures 1 through 73 show each step in the successive process whereby the hooked line will almost certainly have to be sacrificed and lost as the normal line winds up. be freed from the situation. 6th
In the illustration, the sinker is shown on the seabed near a rock formation, such as is encountered when fishing over a reef or from a rocky tip of the coast, or the like. The weight is connected to the fishing line 1 by the untwisting ring of the horizontal bar 7), and has a fishing hook 14t attached to the fishing line at a position separated from the weight. It can move around in water in an attractive manner. When an angler retrieves his fishing line, he should use the line from Figure 7 to Figure 13.
There is a possibility of entanglement with the protruding face of the reef hole, as shown by the rock strata in the figure.

FIG. 7 shows by oval dashed lines the possible trajectory of the end of the extension 11 as the weight rotates with respect to the fishing line 16 due to the movement of the water. The twister tS, which allows an unobstructed rotational action, is aligned perpendicularly with the fishing line 16 running over the edge of the debris, and the twister tS is located at the bend between the crossbar 7 and the leg rim. is shown located at . This orientation depends on the shape of the weight and the IT distribution. The center of mass of the weight, when supported as shown in FIG. 7, pivots to assume the position shown and tilts the extension ii as shown.

If an attempt was made to reel in the fishing line, the weight would fail to pass over the rock ledge. By lowering the fishing line slightly until the weight has no bulge, the weight will rotate freely due to the agitation of the water. Suppose that the weight achieves the direction shown in Figure 7. When the fishing line is reeled in,
The extension // engages the underside of the ledge, 9L, and upon application of further force, the force pivots around the point of contact between the extension // and the ledge, causing the first and second The orientation of the weights shown in the figure is achieved.

Up to this point, the twister 15 has been positioned at the bend between the crossbar 7 and the leg. The main thing is number i.

In the more upright position shown, the reconnection to the crossbar 7 is accomplished by continuing to apply force to the fishing line 16 from a position near the leg along the crossbar to the leg t. be moved towards. Figures 1O to 1J show a further step in the "turning" of the weight to the position without the ledge L, whereby the fishing line 16 is free to lift the weight into a position free of the reef hole. Can be rolled up.

The forward movement of the wide base l of the fishing line in the direction in which the fishing line is wound up (during the stages shown in Figures 10 to 13) is
It is noteworthy that the water encounters resistance and this creates a lifting and rotational force on the weight. This is especially true in the later stages of retrieval, i.e. the stages shown in FIGS. At the bending part where the horizontal bar 7 and the leg part t meet, it can be turned around the connection part of the return tS to the weight.
