Description

[Detailed Description of the Invention] The present invention relates to an improvement of a level wind device in a double-bearing fishing reel.

In the level wind device, which evenly distributes and winds the fishing line onto the spool, the fishing line guide reciprocates from side to side against the tension of the fishing line, so the guide tube installed between the reel side plates has a radial friction force that bears the worm gear shaft. The force, the axial frictional force on the end face, and the sliding frictional force due to the fishing line guide act.

However, in conventional level wind devices, both ends of the worm gear shaft are supported by synthetic resin bearings, and metal guide tubes are fitted to the left and right bearing bushes, which are installed between the reel side plates. If sand, etc. adheres to the fishing line, abnormal friction is likely to occur in the friction part due to rust, lack of oil film, sand encroachment, etc., resulting in a defect that inhibits the operation of the fishing line guide or makes it inoperable. be.

The present invention has been developed to improve these deficiencies.A worm gear shaft, which has a gear on one end that meshes with the gear on the handle shaft, is inserted into the guide tube installed between the left and right reel side plates, and the guide tube is installed between the left and right reel side plates. In a fishing reel in which a fishing line guide engaged with the worm gear shaft is fitted on the outside of the cylinder so as to be slidable left and right, the guide cylinder is made of synthetic resin, and the inner surface on the side where the gear is installed is connected to the worm gear shaft. A spacer part having a diameter larger than that of the guide cylinder is integrally extended to the bearing part, and the end face of the spacer part supports the side surface of the gear fixed to one end of the worm gear shaft. The main points are as follows.

An embodiment of the present invention will be described with reference to the drawings.
One end of the guide cylinder 5 made of thermoplastic synthetic resin is installed between the inner frame 3, and a large spacer part 6 is formed on the outside thereof, and the other end is made of thermoplastic synthetic resin. A bearing 7 made of resin is fitted and fixed to the outside so as not to rotate.
Furthermore, a long hole 8 is bored in the lower part thereof.

Further, a worm gear shaft 11 having a gear 9 fixed to one end and having a reciprocating screw groove 10 formed on the circumferential surface is fitted into the guide tube 5, and the large diameter portion 12 at one end is directly connected to the inner diameter portion of the guide tube 5. The worm gear shaft 11 is rotatably supported by a bearing, and the end face of the spacer part 6 on the outside of the bearing part of the guide tube 5 supports the side surface of the gear 9, and the other end part of the worm gear shaft 11 is supported by the bearing 7. .

A fishing line guide 14 having a fishing line guide hole 13 in the upper part is fitted on the outside of the guide tube 5, and the inner side of the fishing line guide 14 is fitted into the reel side plate support rod 16 through the through hole 15. The guide tube 5 is formed to be slidable left and right, and an engagement pin 19 that engages with the reciprocating screw groove 10 is fitted into the tube hole 18 formed at the bottom, into which the lid 17 is screwed. The gear 9 of the worm gear shaft 11 meshes with the gear 21 of the handle shaft 20.

In the figure, 22 is a spool, and A is a fishing line.

Since the embodiment of the present invention is constructed as described above, when the spool 22 is rotated as is known by rotating the handle shaft 20 and the worm gear shaft 11 is simultaneously rotated by the gears 9 and 21, the reciprocating screw groove 10 is rotated. The engaging pin 19 that engages with the fishing line guide body 1
4 is slid back and forth from side to side on the guide tube 5 to wind the fishing line A onto the fishing line of the spool 22 through the fishing line guide hole 13.

The embodiment shown in FIGS. 6 to 8 is a reel side plate 2.
The bearing 7 is formed integrally with the guide tube 5 from synthetic resin, and a cutout portion 5' for preventing rotation is formed in the fitting portion of the inner frame 3 of the reel side plate 1 of the guide tube 5, so that the inner frame 3 The case is shown in which it is fitted so that it cannot rotate freely. The thermoplastic synthetic resin used in the present invention is preferably polybutylene terephthalate, ABS resin, nylon, etc.
Reinforcement fibers such as glass fiber 30
It is even more effective if the mixture is mixed in a proportion of about 10%.

As described above, the present invention directly supports the worm gear shaft with a bearing on the inner surface of one side of the guide cylinder made of synthetic resin, and integrally forms a spacer part with a larger diameter than the guide cylinder on the outside of the bearing part. Since the side surface of the gear fixed to one end of the worm gear shaft is supported by the end face of the worm gear shaft, it is possible to improve the bearing accuracy of the worm gear shaft and the gear, maintain high meshing accuracy with the gear of the handle shaft, and improve the rotational performance of the worm gear shaft. Strength and durability can be further improved, and the guide tube will not rust, trap oil, or run out of oil during use, which will impede the rotation of the worm gear shaft and the reciprocating movement of the fishing line guide. The fishing line guiding action of the fishing line guide can be performed smoothly without any need for oil, and the worm gear shaft can be supported smoothly without oil, and the number of parts is small, the structure is simple, assembly and disassembly are easy, and the weight of the level wind device is reduced. It also has excellent features and practicality.
