Description

[Detailed description of the invention] Industrial application field The present invention relates to a weight used for fishing, such as a fishing net.

Conventional Technology In bottom gillnet fishing, etc., in addition to the weights attached to the lower shelf nets, additional weights are attached separately in order to quickly set the nets on the seabed and to form net formations. Conventionally, stones or bagged sand have been used.

However, this weight must be adjusted depending on the current, water depth, etc., and it takes time and effort to select a weight of a specified weight, wrap it in a bag or net, and attach it to fishing gear. It has defects such as being troublesome to store because it is not constant.

Problems to be Solved by the Invention In view of these current circumstances, the invention proposes to form a cylindrical shape by winding the lead wire in a spiral manner and closely in multiple layers in the radial direction. The object of the present invention is to provide a weight that is easy to install and store, and which can be easily manufactured to any weight.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a structure in which a lead wire is wound closely in a spiral manner and in multiple layers closely in the radial direction to form a cylindrical shape having a cylindrical hole. The gist is that a heat-shrinkable synthetic resin is shrink-coated on the outer circumferential surface.

Function The present invention allows a rope to be inserted through a cylindrical center hole and attached to a fishing net line to provide sufficient sinking force, and also to easily form a weight of any weight by winding the rope in the axial and radial directions. Furthermore, the heat-shrinkable synthetic resin coating makes the surface smooth and prevents algae from adhering to it, as well as from getting entangled in nets or other objects.

Embodiment An embodiment of the present invention will be described with reference to the drawings. A cylindrical body having a cylindrical hole 2 in the center is formed by winding a plumb wire 1 of an arbitrary diameter tightly in a spiral shape and also in a radial direction in a closely multiplex shape. A weight 5 is formed by forming a heat-shrinkable synthetic resin 4 on the outer peripheral surface of the cylindrical body 3 in a contracted state.

However, when attaching the lever weight 5 to, for example, a bottom gillnet 6, the attachment rope 7 is inserted through the cylindrical hole 2 of the cylindrical body 3 and suspended. It is also possible to install the weight 5 so that its axis is horizontal.

Effects of the invention This invention forms a cylindrical shape by winding the lead wire closely in a spiral and radially in multiple layers, and also coats the outer circumferential surface with a heat-shrinkable synthetic resin in a contracted state. Therefore, by inserting the rope through the central cylindrical hole, it is possible to attach the rope to the fishing gear quickly and reliably, and to provide sufficient sinking force.In addition, the weight can be adjusted by increasing or decreasing the amount of winding in the axial or radial direction. A weight of any weight can be easily obtained while keeping the length or diameter constant, and the heat-shrinkable synthetic resin coated on the surface has a smooth surface that makes it easy to attach to algae and to wrap around nets, ropes, etc. In addition, the cylindrical shape has excellent features and practicality, such as being able to prevent tangling, and making it easy to store and transport them in parallel or piled up inside a ship.
