Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual-bearing reel in which a spool is rotatably supported between side plates of a reel body, and the spool is driven by a handle provided on one side plate.

[0002]

2. Description of the Related Art In the above-mentioned dual-bearing type reel, taking a reel for bait casting as an example, as disclosed in, for example, Utility Model No. 2552677, simplification and operation of the whole reel configuration (shape). A configuration in which the outer shape of the reel body is circular has been known from the aspects of properties and hobbies. This type of bait casting reel requires a high-speed winding function by increasing the gear ratio of a winding drive system provided between the spool and the handle.

[0003]

However, due to the fact that the outer shape of the outer plate of the reel body in which the winding drive mechanism is housed is circular, and that the holding and holding properties when gripped and held are taken into consideration. Since a smooth and rounded shape is desired in the vicinity of the outer peripheral portion of the outer plate, it is difficult to realize a high-speed drive gear with a large size. In other words, if the drive gear is enlarged, the whole reel (the outer diameter of the outer plate)
Or the outer plate must be partially protruded outward, so that the holding and holding properties when gripping and holding are inferior, and also in appearance Inferior.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dual-bearing type reel capable of achieving a high winding speed of a spool without increasing the size of the entire reel.

[0005]

In order to solve the above-mentioned problems, a dual-bearing type reel according to the present invention accommodates a take-up driving mechanism between a frame and an outer plate attached to the frame. The spool rotatably supported by the frame is configured to be wound and rotated by a rotation operation of a handle rotatably supported by the plate, and the outer plate is configured to rotate around a drive gear of the winding drive mechanism. A notch part of which is partially exposed is formed, and the notch part is closed by a cover member.

As described above, by forming a cutout in the outer plate so that a part of the outer periphery of the drive gear can be exposed, the drive gear can be made larger without increasing the size of the outer plate. The picking drive speed can be increased. Further, such an exposed portion is covered with a cover member, and the exposed portion of the drive gear is hidden.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
An embodiment of the present invention will be described. As shown in these drawings, the present embodiment is a dual-bearing type reel whose outer shape is circular (including a substantially circular shape). The dual-bearing type reel 1 has a reel body composed of left and right frames 3a, 3b and outer plates 5a, 5b attached to the sides of the respective frames 3a, 3b by, for example, screws, screwing, fitting, or the like. Have. Between the frames 3a and 3b,
A spool shaft 8 is rotatably supported via bearings 7, 7, and a spool 8a around which the fishing line is wound is integrally attached to the spool shaft 8.

The right outer plate 5b is formed with a cylindrical protrusion 5c. The distal end side of a handle shaft 10a having the handle 10 mounted therein is rotatably supported via a bearing 11. The right frame 3b and the right side plate 5b
A winding space for transmitting a rotational driving force of the handle 10 to the spool shaft 8 to rotationally drive the spool 8a as described in detail below. The mechanism 20 is housed and supported. At the end of the spool shaft 8 on the left frame 3a side, there is provided a backlash prevention mechanism 9 for preventing the spool 8a from over-rotating and preventing backlash when the fishing line is released.

At the end of the spool shaft 8 protruding from the right frame 3b, a pinion gear 21 movable along the axial direction of the spool shaft is attached. The pinion gear 21 is rotatably supported by a pinion shaft 21 a disposed in the space coaxially with the spool shaft 8.
By a switching means (clutch mechanism) not shown, an engagement position at which the spool shaft 8 is engaged with the spool shaft 8 to rotate integrally therewith, and a non-engagement position at which the engagement with the spool shaft 8 is released. Are to be moved between. Specifically, the clutch plate 23 engaged with the circumferential groove 21b formed in the pinion gear 21 is moved along the pinion shaft 21a by operating a clutch switching member (not shown), whereby the pinion gear 21 8 (drive force transmission state; clutch ON), and non-engagement position (spool free rotation state; clutch OF)
Moved to F).

The pinion gear 21 has a handle shaft 1
A drive gear 25 rotatably supported at 0a meshes with the gear, and a drag mechanism 27 is provided between the drive gear and the handle shaft. The drag mechanism includes a metal washer housed in an inner peripheral space of a cylindrically formed drive gear 25 having one end open and arranged so as to rotate integrally with the drive gear, and a metal fixed to the handle shaft 10a so as not to rotate. A washer and a friction engagement member having a lining material disposed between the metal washers are provided. By rotating the drag operation body 30 that is screwed to the handle shaft 10a, the friction engagement member is pivoted. Direction to apply a desired drag force. That is, by rotating the handle 10, the driving force is transmitted to the spool 8 a via the driving gear 25, the pinion gear 21 and the spool shaft 8, and the rotation in the fishing line releasing direction when the fish is hooked. The drag force is adjusted by the action of the friction engagement member and the drag operation body 30.

In the middle of the handle shaft 10a, there is provided a one-way clutch 32 which allows the handle shaft 10a to rotate only in the fishing line winding direction with the cylindrical projection 5c. In addition, a protrusion is provided on the base end side of the handle shaft 10a so as to fit into a predetermined number of holes (two holes are formed at 180-degree intervals in the present embodiment) on the back surface of the drive gear 25. Gear 35 is provided rotatably,
It is configured to rotate integrally with the drive gear 25. The rear surface of the gear 35 is formed flat, and is in contact with a clutch return gear 37 fixed to the handle shaft 10a. The base end of the handle shaft 10a is rotatably supported by the right frame 3b via a bearing 38.

The gear 35 meshes with a drive gear 42 of a level wind mechanism 40 disposed on the front side of the spool 8a. The level wind mechanism 40 includes a worm shaft 43 having a traverse groove formed on the outer peripheral surface thereof and the drive gear 42 attached to an end thereof, a cylindrical body 45 accommodating the worm shaft 43, and engaging with the traverse groove. And an engagement member (not shown) that slides left and right along the cylinder 45 by the rotation of the worm shaft 43, and via a fishing line guide member (not shown) provided on the engagement member. The fishing line wound around the spool 8a is guided. That is, when the handle 10 is rotated, the fishing line guide member is slid left and right via the gear 35, the driving gear 42, and the worm shaft 43, which rotate together with the driving gear 25, and the fishing line is evenly wound around the spool 8a. Is done.

As described above, a flat surface is formed on the back surface of the gear 35 and this is brought into surface contact with the clutch return gear 37 so that it can function as a conventionally used lining material. 35 is engaged with the drive gear 42 of the level wind mechanism 40 and the drive gear 25
As a result, the size of the drive gear 25 in the radial direction can be reduced while keeping the diameter of the drive gear 25 large. That is, since the drive gear 42 is not directly meshed with the drive gear 25, even if the diameter of the drive gear 25 is increased, the outer shape can be reduced in the radial direction.

As shown in FIG. 2, the right outer plate 5b is formed in a circular shape, and the above-described winding drive mechanism 20 is disposed between the right outer plate and the right frame. In this case, a cutout 5d is formed in the outer peripheral portion of the right outer plate 5b at a portion where the drive gear 25 of the winding drive mechanism is located, so that the drive gear 25 is partially exposed. ing. With such a configuration, it is possible to increase the size of the drive gear 25 of the winding drive mechanism without increasing the size of the right side plate 5b, and to achieve high speed during winding. That is, by forming the cutout 5d in the outer plate 5b so that the drive gear 25 can be partially exposed, the drive gear 25 in the outer plate can be kept radially outward with a simple shape of the outer plate. (A shape based on a circular shape without any protrusion) can be displaced as much as possible.
This is possible without increasing the size of the entire reel.

Then, a cover member is separately attached to a portion where the drive gear is exposed to cover the exposed portion. With such a configuration, it is easy to lubricate and clean the drive unit by a simple operation of removing the cover member without removing the entire outer plate. The shape of the cover member is not limited, and may be any shape and size that can cover the notch 5d. However, as in the present embodiment, the outer plate is made circular and the right outer plate 5b is made of a screw 50. When the cover member is mounted on the right frame 3b, the cover member is preferably configured as an annular cover 55 mounted on the outer peripheral portion so as to integrally cover the exposed area of the screw 50 and the drive gear 25. Such an annular cover 55
By attaching the cover member 55, the outer peripheral portion that is most likely to be damaged or deformed is protected by the cover member 55 even when an unnecessary external force is generated at the time of actual fishing, movement of the fishing place, carrying, etc. At the same time, it is possible to replace only the cover member with a new one depending on the degree of scratches and deformation, and it is possible to economically maintain an aesthetic appearance.

In the above-described configuration, the cover member 55 is attached to the frames 3a, 3b and the outer plates 5a, 5b mainly made of an aluminum material or a synthetic resin material, for example, using ultra-duralumin, stainless steel, or the like. Titanium,
By using a high-strength material such as ceramics, the outer peripheral part where unnecessary external force is likely to occur, including dropping during actual fishing, movement of fishing spots, and carrying, is reliably prevented from being damaged or deformed. Thus, functional trouble can be prevented over a long period of time, and aesthetic appearance can be maintained.

As described above, in the embodiment of the present invention, the dual bearing type reel in which the reel body is formed in a circular shape has been described as an example. However, in the above-described configuration, the outer plate is not formed in a circular shape. The same can be applied to a dual bearing reel. Further, the shape of the cutout and the position where the cutout is formed can be appropriately modified by the structure of the reel body and the structure of the winding drive mechanism.

[0018]

As described above, according to the present invention, it is possible to increase the size of the drive gear of the take-up drive mechanism without increasing the size of the entire reel, and to achieve a higher winding speed of the spool. Becomes possible.
