に関するものである。[Detailed description of the invention] [Industrial application field] This invention is suitable for winding up fishing nets, ropes, etc.
This invention relates to a metal fitting for attaching a rubber roller of a hoisting device that holds fishing nets, ropes, etc. between two rubber rollers.

る。[Prior art] Conventional rubber roller installation is carried out by, for example,
As shown in Published Patent No. 60-153367, it consists only of a drum-shaped core metal with wide flanges formed on the top and bottom of a cylinder, and cover plates fixed to the top and bottom flanges, and the flange and cover plate are fixed to each other. The opening of the rubber roller is sandwiched between them.

強い力を要し容易でない。[Problems to be solved by the invention] In conventional rubber roller mounting brackets, the length of the mandrel is slightly longer than the length of the roller so that the mandrel is crimped into the roller. ,Also,
Since the flange is made larger in diameter than the opening of the roller in order to fix the roller, a very strong force is required to press fit the mandrel into the opening of the roller, which is not easy.

るようにした。[Means for solving the problem] Therefore, in the present invention, the length of the core metal that fits inside the rubber roller is made shorter than the length of the roller, and the diameter of the flange is also the same as or smaller than the roller opening. In order to make up for the insufficient length and to clamp and fix the roller, auxiliary plates with a diameter larger than this opening are later inserted between the upper and lower ends of this core metal and the roller opening, and the rubber roller is A cover plate was arranged from the outside of the opening, and the roller was clamped and fixed between it and the auxiliary plate.

このように芯金の長さを短いものとし、かつフ

る。[Example] The core metal 4 has a cylinder 1 in the center and has wide flange parts 2 and 3 at the upper and lower ends, and has a shaft into which a drive shaft (indicated by a dashed line) is inserted. This is hole 5. The diameters of the flange portions 2 and 3 are approximately the same as or smaller than the diameters of the openings 7 and 8 of the rubber roller 6. An auxiliary plate 9 made of a thin metal plate connected to the flanges 2 and 3 at both ends of the core metal and having a diameter larger than the diameter of the openings 7 and 8 of the rubber roller 6 has a connecting surface 9a with the core metal. The flange portions 2 and 3 are formed into a recessed portion such that the flange portions 2 and 3 of the flange portions protrude and engage with each other. The outer portion of the auxiliary plate 9 is a convex stepped portion 9b whose circumference is cut out to have the same diameter as the openings 7 and 8 of the rollers. roller 6
The cover plate 10 that presses the opening 7 of the roller from the outside is cut out around the inside to form a convex step 10a having the same diameter as the opening 7 of the roller, and this convex step 10a and the convex step of the auxiliary plate Part 9b
A cavity is formed on the side surface of the joint with the roller, and the height of this cavity is the same length as the thickness of the opening end of the roller.

It is advantageous to form a protruding edge that engages with the stepped portion 7a provided at the open end of the rubber roller, since the roller can be more securely locked. A shaft hole is also drilled in the center of this cover plate 10, and the drive shaft 11 is connected to the cover plate 10,
It is adapted to be inserted into each shaft hole 5 of the auxiliary plate 9 and the core metal 4. In addition, the drive shaft 11
The projection 11a provided on the side surface of the metal core engages with the groove 5a provided in the shaft hole 5 of the metal core to prevent rotation. The tip end 11b of the drive shaft 11 is fixed to the lower cover plate 10 with a screw 13.

Since the opening diameter is approximately the same as or smaller than the diameter of the opening, it is easy to insert the core bar into the roller 6, and after inserting the core bar 4 into the roller 6, the thin auxiliary plate 9 is inserted. Since the cover plate 10 is placed outside the opening and the three parts are fixed, assembly becomes very simple.
