A protected cutting tool for rescuing marine life entangled in ghost nets, fishing lines, and plastic waste.

Abstract

The invention relates to a cutting tool used to remove debris such as ghost nets and fishing lines from marine life. The key innovation of the invention is the use of a monolithic (one-piece) compliant mechanism that eliminates problems such as assembly, corrosion, and jamming associated with multi-part pivoting mechanisms. The tool comprises a fixed handle, a movable handle, and a flexible connecting zone between them that bends when force is applied. In a preferred manufacturing method, this monolithic structure is created using multiple materials; parts providing overall rigidity to the body can be made from a biodegradable material, while the flexible connecting zone can be made from a material with different properties, such as PLA. The user's squeezing action causes the hook jaw, which has a protected blade, to close through elastic deformation of the material, and the cutting operation is performed. This design offers high reliability, low cost, and maintenance-free performance, especially for corrosive marine environments.

Description

1 TARIFF 5 Methods for Rescuing Marine Life Entangled in Ghost Nets, Fishing Lines, and Plastic Waste Protected Cutting Tool Technical Area The invention relates to handheld cutting tools. More specifically, the invention concerns animal rescue. Ghost nets, fishing line 10, designed for use in marine operations, where marine life gets entangled. It relates to cutting tools used for safely removing hazardous waste such as waste. State of the Art Currently, standard divers are generally used in marine life rescue operations. Knives, scissors, or general-purpose safety cutters are used. Standard diver 15 The knives, because of their exposed sharp edges, are particularly dangerous when attacking a struggling and stressed animal. Risk of injuring both the animal and the rescue personnel when used near the animal. Scissors, however, can be difficult to use with one hand and handle thick ropes or layered nets. It cannot provide enough force to cut. Some safety circuit breakers available on the market (for example) Although seatbelt cutters (or similar devices) have a protected blade, they are usually thick and hard, around 20 inches. They are not strong enough or have a sufficient opening to cut through marine waste. This None of the solutions address the specific challenges of marine life rescue operations (the animal's skin (non-damaging, able to cut thick and complex waste, easy one-handed underwater use) eye It was not specifically designed with this in mind. Purpose of the Invention The biggest technical problem presented by solutions available in the current state of the art is cutting. There is a risk of injuring the marine animal during the process. An open blade can cause the animal to injure itself with sudden movements. It can easily harm the animal. Another problem is that even when the knife is not exposed, the available tools... 30 has sufficient strength and / or design to cut through thick and tangled ghost nets and ropes. It is the lack of such a feature. The invention aims to solve these technical problems. The invention provides... The most important advantage is that the cutting blade is completely enclosed within a protective housing. This allows... Even if the tool comes into contact with the animal's skin, it will not cause any cuts or injuries. Its hook-shaped body is wrapped around the throat and limbs of the marine creature and is about to be cut off. It's great for one-handed operation, easily gripping the material (net, fishing line, rope) and guiding it to the blade. 35 It makes it considerably easier. On the market, there are tools that place the blade into the guard slot, but with narrow guard slots. They have difficulty cutting through thick and heavily tangled waste due to this. In addition, new 2 The smooth and rounded outer surface of the developed tool allows it to be safely used on the animal's body. 5 This allows it to be shifted. Thus, the security created by solutions in the known state of the art is reduced. It eliminates risks and makes rescue operations faster and more effective.

[54] Cutting Blade Description of the invention The invention is a flexible mechanism consisting of a body (10) that is entirely in one piece (monolithic). This 25 body (10); a fixed handle (20), a movable handle (30), a hook jaw (50) and these elements It consists of at least one flexible connection zone (40) allowing movement between them (Compliant Mechanism). The fixed handle (20) allows the user to hold the tool firmly with his fingers. It has an elliptical structure through which the user can pass the clamping force. The movable handle (30) allows the user to apply the clamping force. It is a handle. When the user grasps the fixed handle (20) and applies force to the movable handle (30), these two handles 30 The flexible connection region (40) between them deforms elastically (bends). This bending is a Acting like a hinge, the hook jaw (50) closes towards the fixed handle (20). To be cut The material (net, fishing line, etc.) is caught by the mouth of the hook jaw (50). Inside the jaw The cutting blade (54) inside the protected blade housing (52) is closed during this closing action. It cuts / fixes the material. When the user releases the force on the movable handle (30), the flexible coupling 35 Thanks to the material memory of the region (40), the mechanism automatically returns to its original open position. It returns. This design provides a controlled cutting motion without moving parts. 3 5. How the invention can be applied to industry. The invention relates to the serial production of stainless steel, titanium, or impact-resistant polymer materials. It is suitable for production. Especially for marine biologists, coast guard teams, and animal rescue teams. It is designed for use by foundations, dive centers, and volunteer divers. Saving marine life from ghost nets, fishing lines, ropes and similar plastic waste. It is used effectively in operations. 10
