Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an object to obtain a flexible function as a spring by making a plurality of re-deformation resistances after bending of a metal to form a strength. Structure
The material of the metal is heat tempering after processing, and the strength can be freely adjusted. The invention is an invention for generating a spring function by setting the positions of the base point and the support point. ), A spring function is generated, and the support point (3)
By adjusting the distance, the spring strength can be adjusted. This function is used as a stabilizing function of a fishing rod of a marine recreational fishing boat. 2. Description of the Related Art There are a wide variety of springs, such as tension and compression coil springs, plates, disc springs, and the like. Many are used at the center point of the spring function, and there are few structures that configure the spring function apart from the center point, and there is no structure that generates the deformation resistance of the curved portion as the spring function. In addition, metal materials are also limited, and a method of taking measures against metal fatigue by heat treatment has been adopted. [0003] The present invention is an invention in which a flexible spring function is freely configured at the positions of the support point and the base point, and the spring strength can be adjusted and used in two or more steps. (FIG. 2) The reference spring substrate (1) and the spring substrate (2) are fixed at two or more rivets (13), and the second between the support point (3) and the first curved portion (6). A light bending portion is provided above the bending portion (5), and is inserted and fixed at the base point (4). The spring function is such that the substrate fixed at the base point (4) exerts a primary spring function by the compression resistance of the first bending portion (6) when a load over the support point (3), and the second bending portion (5) A secondary spring function is exerted by contacting the upper portion, and a tertiary spring function is generated at the bent portion of the substrate (1) in synchronization. Since the effective length is set for the first curved portion and the second curved portion, the spring function is flexible, and the spring strength is tuned up and down the support point (3), and the strength can be used up to the tertiary spring function, The fatigue life of the metal material can be maintained for a long time, and the strength of the spring function can be freely set by selecting the length and thickness of the material, refining, and the like. [0004] A spring board (1) and a spring board (2) shown in Fig. 1 are fixed at two or more places with rivets (13), and shown in Fig. 3. When the curved portions (5) and (6) are formed by processing as described above, stress for expansion is left in the curved portion (5), and stress for compression is left in the curved portion (6). A metal plastically processed at high pressure stably retains its current shape due to work hardening of the metal and resists deformation pressure as stress. Further, a support point (3) is provided outside the upper position of the second curved portion (5).
The spring function occurs by positioning. It is a structure utilizing the principle of this spring function. Note that the metal includes a metal that is intensely work hardened and a metal of a thermosetting type, and can be freely adopted depending on the application and the spring strength. FIG. 3 shows an example in which a bend is formed in a part of the substrate (1) and the bend (6) is formed so that the bend of the substrate (1) is positioned above the bend (5). , A primary spring and a secondary spring function are formed. Further, the bent portion of the substrate (1) also comes into contact with the upper portion of the curved portion (5), and functions as a tertiary spring. The support point (3) is located at a position farther from the position of the spring function portion, and has a structure in which it is supported by the spring function and absorbs rolling and vibration in synchronization with the fixing bracket (8). [0005] There are a wide variety of metal materials for springs. Heat treatment and surface treatment are applied to light load, heavy load, magnetic, non-magnetic, anti-corrosive, conductive, and the state according to the purpose. The present invention can be adopted in any state by adopting the metal at a temperature lower than the metal yield point, and has a structure in which the spring function absorbs rolling and the seismic effect is enormous, and metal fatigue is minimized. . FIG. 6 is an embodiment in which a lot keeper is mounted on a recreational fishing boat on the sea. The sea surface constantly shakes from 0m to 3m high and low, and more than 3m is considered dangerous for recreational fishing boats. The ship rolls according to the angle of the waves, the height and direction of the waves and the pitch of the waves vary irregularly depending on the strength of the wind. Underwater fishing gear (18) is connected to the tip of the fishing rod (15),
The whole fishing gear always goes up and down according to the state of the ship. Its width is about 3m up and down and the rolling of the ship is up to ± 10
傾斜 Incline to a degree. The movement of underwater fishing gear is adjusted to some extent by the deflection of the fishing rod under the water pressure. However, when the wave height exceeds 1 m, it is difficult to completely absorb the shaking, and the underwater fishing gear becomes unstable. It is difficult for fishermen to accurately grasp, and it is the current situation that anglers adjust themselves on a swaying ship. The lot keeper of the present invention is an effective device that absorbs the sway of the whole ship, prevents instability of the fishing gear in the sea, and allows the player to enjoy recreational fishing safely and enjoyably. Also, a set fitting (22) and a mounting fitting (23) are provided on the rim of the recreational fishing boat as standard equipment, and the detachable lot keeper also has an effect of allowing free use by recreational fishing customers. This principle is not limited to the lot keeper, and is a very effective invention as a safety mechanism for all mechanical devices and a safety earthquake-resistant mechanism for structures. [0007] The present invention is characterized in that metal fatigue can be minimized and a step can be made according to the strength of a flexible spring function, and the base point and support point of the spring function can be adjusted freely. It can be used. The vibration absorption effect is outstanding, and it is an effective method for preventing safety accidents by adopting the structure in the right place. For the purpose of preventing rust, for the case where appearance is emphasized, and for quenching treatment such as (SUS-304) It is also possible to configure a light spring function without performing the above. The effect of boat fishing is that the stability of underwater fishing gear by rolling the boat is not only fun for recreational fishing but also effective for safety during operation,
It is effective to reduce the amount of Komase for collecting fish in the sea and to prevent marine pollution due to overspreading of Komase. The rim of recent high-speed ships is made of steel. As shown in Fig. 7, when the set metal fittings (22) are provided on the rim of the hull and fixed with the mounting metal fittings (23), it becomes a standard equipment fishing gear of the ship, and the angler can fish the boat lightly without bringing his own lot keeper. You can enjoy.
