Abstract

FIELD: amateur and sports fishing. SUBSTANCE: proposed sinker can be used for fishing with fishing rod or spinning. Sinker consists of body made of material whose density is less than that of water and of rod manufactured on material whose density that of water. Rod can be made with bosses inside body and on ends. Sinker can be furnished additionally with detachable rings fitted on rod between end bosses and body and made of the same material as body. This sinker is an additional member for main sinker of tackle. It increases total weight of tackle in air and thus increases casting distance without increasing total weight of tackle in water. EFFECT: enlarged operating capabilities. 5 cl, 7 dwg

Description

 The invention relates to devices for individual fishing with a fishing rod or spinning rod, namely, casting sinkers.

 Known sinker, made in the form of a shell of light material with balls of metal placed inside (description to US patent N 5233786, CL 43-43.12, published. 10.08.93). The disadvantage of the sinker is a simple increase in the weight of the sinker with an increase in the number of balls, which leads to an increase in volume.

 Known sinker, made in the form of a metal rod, on which a washer made of non-metallic material and one or more metal washers are mounted (description of US patent N 3180052, CL 43-43.12, published. 27.04.65). The disadvantage of the sinker is an increase in the weight of the latter, which leads to an increase in volume.

 Known sinker, made in the form of a metal ball with a bracket on which are mounted light and heavy washers (description of US patent N 4450646, CL 43-43.14, published. 29.05.84). The disadvantage of the sinker is that removable parts only change the total weight of the sinker.

 The closest in technical essence and the achieved result is a sinker containing a body of material with a density less than the density of water and placed inside the body along the center line of the insert, made either in the form of a light stick, or a metal ball, or a lead stick. The inserts allow the sinker to be used as a float or as a sinker with the possibility of immersion to a shallower or greater depth (description of US patent N 4477996, CL 43-43.14, published. 23.10.84). The sinker allows you to make a coarse adjustment of the buoyancy, but does not provide fine adjustment.

 None of the known sinkers performs the role of an additional sinker, contributing to an increase in the throwing distance of the hook with the gear, but also does not increase the weight of the gear in the water.

 The technical result from the use of the invention is to increase the total weight and range of casting tackle without changing the weight of the tackle in the water by creating an additional sinker to the main sinker - when casting, the total weight of the sinkers allows you to increase the throwing distance, and if it gets into the water, the additional sinker due to its design " loses weight and acquires minimal buoyancy or partially immerses in water.

 This is achieved by the fact that in a sinker for fishing rod or spinning, made in the form of a body made of a material with a density less than the density of water with an insert made of a material with a density greater than the density of water and means for attaching fishing line, the insert is made in the form of a rod with thickenings located on it - one or several inside the housing and one at the ends of the rod outside the housing, and is additionally equipped with one or two removable rings that are located on the rod between the bulges at the end of the rod and the housing, and are made of Container material body; the body can be made in the form of a torpedo; thickenings on the rod inside the housing can be made in the form of a ball or toroid; the body and rings can be made of closed cell foam; the rod may be made of lead.

In FIG. 1-3 shows a sinker, respectively, with one, two and three bulges inside the hull;
in FIG. 4 - sinker used as a surface float;
in FIG. 5 - sinker used at shallow depths;
in FIG. 6 - removable ring;
7 is a layout on the fishing line sinkers for fishing rods or spinning.

 The sinker contains a housing 1, an insert placed in the housing, made in the form of a rod 2 with bulges 3 inside the housing 1 and bulges 4 at the ends of the rod 2. On the rod 2 between the bulges 4 at the end of the rod and the housing are removable rings 5 made with the possibility of installation and easy removal from the rod 2. The housing can be made in the form of a torpedo (shown in the illustrations schematically) from a material with a density less than the density of water, for example, closed-cell foam (polyethylene foam). This torpedo can be represented in the form of a body of revolution with a surface formed as a result of rotation of the ellipse around a major axis. Each thickening 3 on the rod inside the housing can be made in the form of a ball, or an ellipsoid, or a toroid. Thickening 4 at the ends of the rod can be made in the form of balls. On the bulges 4 there are slots (not shown) for attaching the fishing line 6. The rod 2 can be made of a material with a density greater than the density of water, for example, lead. The removable rings 5 are made of the same material as the material of the housing.

 The weight of the body, rings and rod is selected in such a way that when the rings are worn, the sinker is on the surface of the water, and when one ring is removed, it goes under the water with minimal buoyancy.

 The sinker 7 is fixed on the fishing line above the main sinker 8 and below the main float 9 (in the case of a fishing rod), as shown in Fig.7, and acts as an additional load when throwing gear.

In the water sinker can be used:
- as a float (as shown in Fig. 4). In this case, two rings are used, and the entire device floats on the surface of the water;
- as a sinker with minimal buoyancy (as shown in Fig. 5).

 In this case, one ring is used. The device takes a vertical position, or is located at an angle to the surface of the water.

 The device allows you to increase the total weight of the sinker in the air, thereby increasing the range of throwing gear and at the same time not to increase the total weight of the gear in the water.
