Description

[Detailed Description of the Invention] This invention relates to a ball net frame, and more specifically to a lightweight ball net with good handling properties and is ideal for large ball nets such as those used for amberjack fishing.

Usually, small-sized ball nets use an integrally molded frame made of bamboo, wood, aluminum, stainless steel, etc.
A foldable metal frame is used for large ball nets for fishing for amberjack and the like.

However, such a fishing net equipped with a large metal frame is heavy, making it extremely inconvenient and dangerous to handle on the shore.

Therefore, the inventor of the present invention has been considering ways to reduce the weight of large-sized ball nets, and has found that by using a curved fiber-reinforced resin hollow tube, the weight can be reduced while maintaining appropriate rigidity. found.

However, the integrally molded product has disadvantages such as inconvenience in carrying and handling.

Therefore, the present invention aims to solve the inconvenience of an integrally molded frame and provide a lightweight, large-sized bead frame with good handling properties. The fiber-reinforced resin frame described above is connected by a hinge-type joint to make it foldable.

The fiber-reinforced resin frame used in the present invention is a fiber-reinforced resin frame obtained by impregnating glass fiber, carbon fiber, or other high-modulus fibers in a thermosetting resin, and then forming a curved body using a known method. Examples include thermosetting resin laminated tubes, thermoplastic resin curved hollow tubes obtained by mixing high elastic modulus fibers with thermoplastic resin, and injection or extrusion molding.

For hollow tubes, long fibers such as high-strength, high-elasticity glass fibers, carbon fibers, alumina fibers, boron fibers, silicon carbide fibers, etc. are used, and thermosetting resins such as epoxy resins, phenolic resins, and polyester resins are used. It is desirable to use a curved hollow tube impregnated with a synthetic resin, hardened and bonded.

Also, instead of using a curved tube, it is also possible to use a straight tube, give the hinged joint a curvature, and assemble it into an annular shape.

As the hinge type fitting, those made of aluminum, stainless steel, resin molded products, etc. can be used.

Hereinafter, one embodiment of the present invention will be explained based on the drawings. Fig. 1 shows a dazzling net constructed by attaching a dazzling frame according to the present invention to a handle rod, and the dazzling frame A consists of four fiber-reinforced Resin frame 1, 2, 3, 4
and hinge type joints 5, 6, 7, and 8 that connect the frames 1, 2, 3, and 4 to form an annular shape.

The four fiber-reinforced resin frames 1, 2, 3, and 4 are made of long fibers of high strength and highly elastic carbon fibers, impregnated with epoxy resin, hardened and bonded, and bent into an arc of 1/4 of the circumference. A molded hollow tube is used.

The hinge-type fittings 5, 6, 7, and 8 are made by pivoting stainless steel rods a and b so as to be rotatable about the pivot c. ' extends downward, and a threaded thread 9 is cut on the circumferential surface of the protruding portion, so that it can be screwed and fixed to the handle bar B.

In addition, the other hinge-type joints 6, 7, and 8 are simply opened and closed, but the hinge-type joint 7 located at the corresponding position to the hinge-type joint 5 does not open more than 180 degrees, and can only open and close at a moderate angle. It shall have switching resistance.

The rods a and b in the hinged joints 5, 6, 7, and 8 are the same as those in the fiber-reinforced resin frames 1 and 2,
It is connected to 3 and 4 via intermediate members as described below.

The connection structure using the intermediate members is shown below. 10 is a spacer made of resin, wood, metal, etc.; 11 is a terminal reinforcing cap of the fiber-reinforced resin frames 1, 2, 3, and 4; An insertion hole 12 into which rod rods a and b of hinge-type joints 5, 6, 7, and 8 are inserted is bored in the shaft core, and rod rods a and b are inserted into the terminal reinforcing cap 11. Through hole 13
has been opened.

To assemble the above-mentioned members, first attach the rods a and b of the hinge type joint to the terminal reinforcing cap 1.
1 through the through hole 13 of the spacer 10, and after applying adhesive to the circumferential surfaces of the rods a and b, the rods a and b are inserted into the insertion holes 12 of the spacer 10 and fixed with adhesive. An adhesive is applied to the circumferential surface of the spacer 10 to fit and adhere it inside the hollow tube of the fiber-reinforced resin frame, and a terminal reinforcing cap 11 is placed on the end of the frame. After drilling a hole through the resin frame 1, spacer 10 and rod a, a pin 14 is inserted and fixed by caulking.
(See Figures 2 and 3) Figure 4 is an exploded perspective view of the connection between the handle bar B and the hinged joint 5, and shows the connection between the fiber-reinforced resin frames 1, 4 and the joint 5. is similar to the structure described above, with the axis
The only difference is that c' is screwed onto the handle bar B.

In addition, in the figure, 15 is a net attached to the net frame A.

In addition, the above embodiment uses four curved fiber-reinforced resin frames, and when they are connected and expanded, it becomes an annular shape. is not only a circular ring, but also a triangular ring,
It may be either a square ring or an elliptical ring, and the fiber-reinforced resin frame constituting the frame may be not only an arcuate curved rod but also a straight rod, and the number of rods used can be selected appropriately according to the shape. It's something you get.

Since the ball net frame according to the present invention has the above-described structure, it is possible to provide a frame that is lightweight and easy to handle.

That is, when a frame is attached to the tip of a long handle rod to make a finished product, the frame is light and can be easily handled on the shore.

Therefore, the danger associated with the inconvenience of handling, which is associated with large-sized nets made of metal frames, can be eliminated, and safe loading operations can be performed.

In addition, the rod that rotatably connects the fiber-reinforced resin frame is fitted into the axis of the spacer that is fitted and fixed inside the side end of the frame, and is inserted from the outside of the terminal reinforcing cap fitted on the side end. Since the connection is made by a pin inserted perpendicularly to the axis, it is possible to connect and integrate the frame without causing any tears or cracks. It is possible to ensure integration with the

Moreover, since the frames that make up the frame are made of fiber-reinforced resin rods, they have a suitable degree of rigidity, and the frames are connected with hinged joints so that they can be folded freely, making it very convenient to carry. It is something.

Furthermore, since the fiber-reinforced resin frames constituting the annular frame are interconnected via spacers, terminal reinforcing caps, and rod rods, the side edges of the frame are reinforced and protected, and the rod rods and side ends of the frame are It is possible to reliably prevent cracks from occurring at the joints between the frame and the frame, and provide a sturdy and strong frame that can withstand long-term use.
