Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly to a spool reinforcement structure. 2. Description of the Related Art A fishing reel winds a fishing line on a spool by a fishing line winding mechanism driven by rotation of a handle. It is known that the spool is formed of a low-cost, lightweight, mass-productive resin, and a rib is formed in a space inside the spool in order to reinforce the structural strength. A structure in which a metal collar is provided on the inner peripheral surface of the spool to reinforce it is disclosed in Japanese Utility Model Laid-Open No. 1-168169. [0005] However, in the case where the ribs are formed in the space inside the spool, the ribs are generally formed of the same material as the spool. In addition, the thickness of the rib itself is required, resulting in an increase in weight, and it has been difficult to reduce the weight of the spool alone. Such an increase in the weight causes the spinning reel to become heavier and the hands holding the reel and the rod become tired when fishing for a long time. In addition, in the case of a dual-bearing type reel, the weight of inertia increases when the spool rotates, which causes problems such as inducing backlash and reducing the flight distance when throwing and throwing a device. Further, the above-mentioned reinforcing member provided with a metal collar prevents bending of the fishing line winding body portion of the spool when winding the fishing line. In this case, however, a separate collar is attached. An increase in weight is unavoidable, and the problem remains that the number of parts increases and the number of assembling steps increases, thereby increasing the manufacturing cost. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has a light and high rigidity fishing reel capable of reducing costs by simplifying a molding and assembling process. The purpose is to provide. SUMMARY OF THE INVENTION The present invention provides a handle rotatably supported on a reel body, a spool supported on the reel body, and a fish configured to wind a fishing line around the spool. In a fishing reel, the spool is formed of resin, and a spool winding body on an inner peripheral surface of the spool.

It is characterized in that it is integrally formed at predetermined intervals, and a metal film layer is formed so as to cover at least the surface of the rib of the spool. Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the following description, the pole tip side will be described as the front side, and the pole butt side will be described as the rear side. FIG. 1 is an overall side view showing a fishing reel according to a first embodiment of the present invention, FIG. 2 is a side sectional view showing a spool, FIG. 3 is a sectional view taken along line AA in FIG. Is an enlarged sectional view showing the spool, and FIG. 5 is an enlarged view of the state shown in FIG. The first embodiment of the present invention is applied to a spinning reel, and a fishing line take-up mechanism, a guide line to a spool of a fishing line, and the like are basically the same as those of a widely known spinning reel. As shown in FIG. 1, a reel 2 which is rotated by operating a handle H, and a spool 3 which is moved back and forth by a traverse mechanism are provided at the front of the reel body 1. In the figure, reference numeral 4 is the spool 3
This is a spool shaft that supports. A pair of support arms 21 are formed on the rotor 2 at symmetrical positions so as to protrude toward the distal end, and a bail 23 is attached to the support arm 21 via a bail support member so as to be able to turn over. Although not particularly shown, one of the support arms 21 is provided with a line roller for guiding the fishing line to the line winding portion of the spool 3. The spool 3 for a spinning reel in the first embodiment has a winding body 30 for winding fishing line,
It has a spool bearing portion 31 located at the center of the inside of the winding body 30, and a wall-shaped portion 33 integrally connecting the winding body 30 and the spool bearing 31. Inside the winding body 30 of the spool 3, ribs 35 projecting from the inner peripheral surface of the winding body 30 toward the spool bearing 31 are provided at predetermined intervals in the circumferential direction. I have. The rib 35 is also integrally connected to the wall portion 33 to reinforce the strength of the winding body 30 of the spool 3. As the base material of the spool 3, for example, polyamide, FRP, ABS (acrylonitrile-butadiene-
Styrene) resin, polycarbonate, or a composite material thereof is used.
1. The wall 33 and the rib 35 are integrally formed. A metal film layer 39 is formed on the inner and outer peripheral surfaces of the base material of the spool 3 as best seen in FIG. 5, thereby increasing the rigidity of the entire spool. Here, various metal materials such as chromium, aluminum, gold, nickel and the like are used for the metal film layer 39. These metal materials are subjected to plating and vapor deposition (physical vapor deposition, chemical vapor deposition). Process) and the like. The thickness of the metal film layer 39 is not particularly limited, but is preferably at least 1 micron or more in order to obtain a certain degree of rigidity. Next, a second embodiment of the present invention will be described. As shown in FIG. 6, the spool used for the fishing reel according to the second embodiment is provided with ribs 36 and 37 on the front and rear sides of the wall 33 on the 3A. The rib (first rib) 3 on the rear side of the wall portion 33
6 is formed so as to extend from the cylindrical inner peripheral surface of the winding body 30 to the spool bearing 31 through the wall 33. The first ribs 36 are also provided at predetermined intervals in the circumferential direction. By extending the first ribs 36 in this way, the strength of the spool is increased. Also in the first embodiment, the strength is increased by extending the first rib 36 to such a spool bearing portion 31. Further, a second member disposed on the front side of the wall-shaped portion 33 is provided.

The spool 3A is also made of a material such as FRP, ABS resin, polycarbonate, or a composite material thereof, and is integrally formed with a winding body 30, a spool bearing 31, a wall 33, and ribs 36 and 37. ing. Then, a metal film layer is formed on at least the inner surface side of the spool 3A in the same manner as the spool 3 of the first embodiment to improve the strength. Next, a third embodiment will be described. In the third embodiment, as shown in FIG.
A plurality of rows of ribs 39 arranged at predetermined intervals in the axial direction on the inner peripheral surface of the winding trunk portion 30 of B and behind the wall portion 33 are formed integrally with the spool 3B. The plurality of rows of ribs 39 are also arranged at regular intervals in the circumferential direction. A metallic coating layer is formed on at least the inner surface of the spool 3B having the above-mentioned structure at least on the inner surface side to improve the strength. Next, a fourth embodiment will be described. The fourth embodiment is applied to a dual-bearing type reel, and is shown in FIGS. The overall configuration of a fishing reel according to the fourth embodiment is basically the same as a general dual-bearing type reel, and is provided between a pair of side plates 8A and 8B provided on both sides of a reel body 7. A spool 9 is rotatably supported via a spool shaft 8. The spool 9 is driven to rotate by the handle H, and the fishing line is wound by the fishing line guide portion G while traversing the winding body 90 of the spool 9 evenly. A rib 95 is integrally provided so as to extend from the winding body 90 of the spool 9 to the space between the spool bearing 91 through the wall surface of the wall 93. That is, as can be seen from FIG. 10, the rib 95 is formed radially from the spool bearing 93. The rib 95 is a wall 93
Is provided on the wall surface on the handle H side of
This is for improving the strength on the driving side. Also in this spool 9, the winding body 90, the wall 93, the spool bearing 91, and the rib 95 are integrally formed of a material such as FRP, ABS resin, polycarbonate, or a composite material thereof, and at least. A metal coating layer is formed on the inner surface of the rib 95 side. The specific shape and number of the ribs in each of the above embodiments are not limited to those shown in the drawings. As described above, according to the present invention, the sp
