Description

[Detailed explanation of the idea] The present invention relates to a frame for a double-bearing fishing reel.

The above-mentioned conventional frame body has the spool shaft supported by the left and right side plates, and the reel rotation transmission mechanism is built into the gear plate provided in correspondence with the above-mentioned both side plates. The main pillars were connected at regular intervals, so when strong line tension was applied to the spool, there were strength problems such as the spool shaft bending and the frame twisting. However, the spool and the frame come into contact with each other, making it impossible to rotate the spool stably, and assembly is difficult, resulting in poor productivity and failure to improve assembly accuracy.

Therefore, as a result of studies in view of the above-mentioned conventional difficulties, the present invention aims to improve the machining accuracy, assembly accuracy, and strength of the entire reel, obtain stable rotation of the spool, and improve productivity. This is what you get from the frame.

The drawings showing the embodiments of the present invention will be described in detail below.
In Figures 1 to 3, the left and right inner frame plates 2, 2' fixed to the inside of the left and right side frame plates 1, 1', respectively, the reel mounting leg 3, the hollow main column 4, etc. are integrally molded. , one inner frame plate 2 is provided with a through hole 6 having an inner diameter 1' that is approximately the same as or slightly larger than the outer diameter 1 of the flange 5a of the spool 5, and the other inner frame plate 2' has a bearing part 8 for the spool shaft 7 formed therethrough, and a plurality of shaft holes 9 are formed in both inner frame plates 2, 2' as necessary.
* is provided so that the reel rotation transmission mechanism 10, fishing line guide mechanism 11, and others can be incorporated therein.

In this case, a recess 12 having the same inner diameter as the through hole 6 is provided on the inner surface of the inner frame plate 2' so as to be coaxial with the through hole 6, and the flange 5a of the spool 5 is housed therein. The bearing portion 8 is formed by fitting a bearing 8b such as a bushing into a through hole 8a provided in the inner frame plate 2'.

Further, the inner frame plates 2, 2', the reel mounting legs 3 and the hollow main column 4 are integrally molded by guy casting from any desired material suitable for forming them.

In the above configuration, when assembling a reel using this, the spool shaft 7 is inserted through the through hole 6 and supported through the bearing part 8, and the ends of the left and right flanges 5a, 5a of the spool 5 are The pinion 13 is fixed to one end 7a of the spool shaft 7 as shown in FIG. 2, and the other end is connected to the outside of the other inner frame plate 2'. It is supported via a bearing 15 on a side frame plate 1' fixed with a shaft 14, screws (not shown), etc., and the other end 7b
is supported on a bearing portion 16 of a side frame plate 2' fixed to the outside of one inner frame plate 2 by the connecting shaft 14 and the like, and furthermore, a fishing line guide mechanism 11 and a ratchet are installed in each of the above-mentioned shaft holes. A shaft 17 and other necessary members for a double-bearing reel are installed, and the ratchet shaft 17 is interposed with a main gear 19 that meshes with a ratchet 18 of a clutch mechanism (not shown) and the pinion 13, and a drag mechanism 20. , a start lug 21. at its protruding end. The handle 22 etc. are attached and assembled.

As explained above, according to the frame according to the present invention, since the left and right inner frame plates 2, 2' and the reel mounting legs 3, etc. are integrally molded, it is not necessary to process the gear plates individually as in the conventional example. Not only can it be processed at once without the need for processing, but also the peripheral inner frame plates 2, 2'
Since the spacing between and the axes of the shaft holes 9, 9 of the fishing line guide mechanism 11, etc. are constant, the reel can be assembled easily and the processing accuracy and assembly accuracy can be improved. The bodies 1, 1' include left and right circumferential inner frame plates 2, which are integrally molded.
Since they can be fixed individually to the inner frame plates 1 and 2', these fixings are easy, and there is no twisting between the frame plates 1 and 1' on both sides. Since the spool shaft 7 is supported by the section 8, the bearing interval of the spool shaft 7 can be shortened, and the shaft is less likely to be bent, improving the mechanical strength of the entire reel, thereby providing strong line tension to the spool. It is possible to prevent the spool 5 from coming into contact with the frame body even when the spool 5 is applied, so that stable spool rotation can be obtained at all times.Furthermore, since it is integrally molded, the cost can be reduced and it can be provided at a low price. effective.
