Abstract

PURPOSE:To improve operating efficiency of a reel with a dragging mechanism by connecting and disconnecting a substrate part of an output gear except an output gear for the minimum speed in speed changing output gears from an output rotating unit. CONSTITUTION:A pin (28a) additionally attached to a rotation operating part 28 is engaged with a slot (29b) of a sliding plate 29. If the rotation operating part 28 is rotated and operated, the sliding plate 29 is moved to the side of an output shaft. Consequently, protruding parts (29a) and (29b) push and move a shift fork 26 to the side of a handle. As a result, an output shaft 3 is disengaged to disconnected a clutch. Thereby, the output shaft 3 is slid, moved to the side of the handle and disengaged from a spool shaft (2A) to disconnect the clutch. When the rotation operating part 28 is returned, the shift fork 26 is moved to the side of the spool with return springs 30 and 30 following the movement of the sliding plate 29 to the side opposite the output shaft. As a result, the output shaft 3 is moved to the side of the spool and engaged with a spool shaft (2A) to connect the clutch.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a reel with a drag mechanism, and more specifically, it is provided with an input shaft that is rotatably operated and an output shaft that is interlocked and connected to a spool. A drag mechanism is interposed between the input shaft and an output rotating body that rotates relative to the input shaft, and a plurality of speed change output gears are provided so as to be rotatable relative to the input shaft, A plurality of input gears that are always in mesh with each of the plurality of transmission output gears are provided to rotate in conjunction with the output shaft, and a plurality of input gears are provided to rotate in conjunction with the output shaft, and the output side rotating body and the plurality of transmission output gears are connected to each other. The present invention relates to a reel with a drag mechanism in which a clutch mechanism for speed change is interposed between the reels.

[Conventional technology]

The aforementioned reel with a drag mechanism has previously been proposed by the applicant, and its structure is shown in FIG.

This reel has a cylindrical shaft-shaped output rotating body (5) fitted around an input shaft (1) which is rotated by a handle (10) so as to be relatively rotatable. A disk-shaped input rotating body (4) provided at both ends to rotate integrally with the input shaft (1).

Friction plates (13), (13) are arranged between the drag mechanisms (A), (A) and (4). In addition, output gears (6) and (7) for speed change with two high and low stages are provided, which can freely rotate relative to the human power shaft (1), and between these gears (6), (7) and the output side rotating body (5). Clutch mechanism for shifting (B
) is interposed. This clutch mechanism (B) has a meshing shaft (32) fitted onto the output rotating body (5) so as to rotate integrally therewith and to be relatively slidable in the axial direction.
2) The speed is changed by the sliding operation. Specifically, a claw (32a) is formed at the tip of the engagement shaft (32) on the side opposite to the handle.
) and slide this meshing shaft (32) in the axial direction, and the water (32a) is transferred to the claw part (7d) of the low-speed output gear (7) and the claw part (6d) of the high-speed output gear (6). ), the high-speed transmission state and the low-speed transmission state can be arbitrarily selected.

A reel with a drag mechanism based on this proposed technology is, for example, as shown in Japanese Patent Publication No. 10788-1988,
The type of reel that automatically changes speed from high speed to low speed when a fish is caught on the fishing line and the rotational load on the spool increases, but as a result, the drag mechanism is only used when changing speed is always low. This device is useful as it has the advantage that high and low speeds can be arbitrarily selected according to the angler's preference, and fishing using the drag mechanism can be enjoyed in either high or low speed change state.

[Problem to be solved by the invention]

However, the reel with a drag mechanism according to the prior art has the following disadvantages.

In other words, since the meshing shaft meshes with the high and low output gears in a meshing manner, a neutral state is always provided during gear shifting to prevent double meshing, and as a result, there is no meshing shock (change shock) caused by gear shifting. In order to avoid a neutral state in which the drag does not work, the gear cannot be changed when the fishing line is under tension due to fishing or a fish is hooked.

In addition, the value of the drag force caused by the drag mechanism changes depending on the gear ratio of the selected side, so the drag force changes between low and high speeds, which has a negative impact on the usability, and also causes the drag force to change when shifting from low to high speed. There was also a risk that the thread would become too large and cause thread breakage.

An object of the present invention is to eliminate the above-mentioned disadvantages and provide a reel with a drag mechanism that is easier to handle.

[Means to solve the problem]

Therefore, the present invention provides the reel with a drag mechanism described at the beginning, in which each of the plurality of speed change output gears includes a base portion, a tooth body portion having teeth, and when the base portion is rotated in the line winding direction. and a one-way clutch portion that rotates the tooth body portion and the base portion integrally, and the base portion of the lowest speed output gear among the plurality of speed change output gears is connected to the output side. The transmission clutch mechanism is connected to a rotating body so as to rotate integrally at all times, and the transmission clutch mechanism includes a base portion of the output gears excluding the lowest speed output gear among the plurality of transmission output gears, and the output side rotation body. The device is characterized in that it is configured to disconnect and disconnect from the device.

[For production]

Taking a high-low speed two-speed transmission as an example, the operation will be explained with reference to FIG. When the human-powered shaft is rotated in the line winding direction while the connection is being made in a high-speed transmission state, the rotation is transmitted to the output rotating body by the frictional force of the drag mechanism, and its teeth are transmitted through the base of the high-speed output gear and the negative direction clutch. The body rotates to drive the high-speed manual gear, resulting in high-speed transmission. At this time, the low-speed input gear, which rotates together with the high-speed input gear at a rotational angular velocity of 2, also rotates the teeth of the low-speed output gear, but due to the gear ratio relationship, the low-speed input gear rotates the teeth of the low-speed output gear. Since the rotational angular velocity V3 of the body is in the same direction as the rotational angular velocity V of the high-speed output gear and is faster (V3>Vl), the low-speed output gear is The tooth portion of the low-speed output gear can rotate relative to the base portion of the transmission gear, and the above-mentioned high-speed transmission state can be realized.

At this time, when a fish is caught and the spool is reversed due to the load, the low-speed input gear rotates at a rotational angular velocity of V in the opposite direction to that used when winding the line, and the low-speed output gear rotates in the opposite direction at a rotational angular velocity of V3. The reverse rotation is transmitted to the output rotating body through the one-way clutch of the low-speed output gear and its base portion, and the drag mechanism comes into operation. At this time, at the same time, the high-speed input gear rotating at a rotational angular velocity v1 reversely drives the tooth body portion of the high-speed output gear at a rotational angular velocity v2, and the base portion of this high-speed output gear is connected to the base portion of the low-speed output gear. It comes to rotate at the same rotational angular velocity V3 as the low-speed output gear through the output-side rotating body of constant mesh and the clutch mechanism for speed change, but the tooth part and base part of the high-speed output gear rotate in the same direction. Furthermore, due to the gear ratio, the rotational angular velocity of the tooth body is V.
2 is slower than the rotational angular velocity of the base part ■3 (
V2<v3), the action of the one-way clutch built into this high-speed output gear allows relative rotation of its tooth body and base, and the drag action state via the low-speed output gear is maintained. It can be achieved.

Next, the clutch mechanism for speed change is set to a low-speed transmission state in which the base of the high-speed output gear and the output rotating body are disconnected, and when the input shaft is rotated in the line winding direction, the friction of the drag mechanism As a result, rotation is transmitted to the output rotating body, and the teeth of the low-speed output gear rotate via the base portion and the one-way clutch to rotationally drive the low-speed input gear, resulting in a low-speed transmission state. At this time, the high-speed input gear, which rotates integrally with the low-speed input gear, also rotates the teeth of the high-speed output gear, but the base of the high-speed output gear has already disconnected from the output rotating body. Since it is leaning down, it is structurally in a state where it can idle, and the low speed transmission state is not affected in any way.

At this time, if a fish catches and the spool rotates in the opposite direction due to the load, the high-low and high-speed input gears will each drive the high-low and high-low output gears to rotate in the opposite direction, but as mentioned above, the high-speed output gear becomes idle. Therefore, the reverse rotation is transmitted to the output rotating body through the teeth of the low-speed output gear, the one-way clutch, and its base portion, and the drag mechanism is activated.

In other words, according to the present invention, (a) There is no neutral position in gear shifting, so there is less change shock associated with gear shifting, and gear shifting operation is possible even when a rotational load is applied.

(0) Furthermore, as described above, when the drag mechanism operates, drag force always occurs in the lowest gear shift state, regardless of the gear shift state, and the drag force is always constant.

[Effect of invention idea]

Therefore, it is possible to change the speed as desired as before, and while it is possible to fish using the drag force in each transmission state, due to the effect of (a), the speed can be changed even while fishing and reeling in the line. In addition, there is less change shock associated with gear shifting operations, and the effect of (b) ensures that the drag force does not change at all times regardless of gear shifting, which eliminates the conventional disadvantages and improves operability. We were able to provide a reel with a high-value drag mechanism.

An output rotating body (5) is fitted onto the input shaft (1) so as to be relatively rotatable, and a low-speed output gear (7) and a high-speed output gear (6) are connected to the input shaft (1). These high and low speed change output gears (6, (7)

(70), and rings (61) and (71) that urge these claws (60) and (70) to swing in the outer radial direction.
) etc.

A pair of friction type drag mechanisms (AI), (A2) are interposed between the output side rotary body (5) and the input shaft (1), and the output side rotary body (5) is connected to these drag mechanisms (AI), (A2). At).

It is interlocked with the input shaft (1) by means of friction transmission (A2).

The pair of drag mechanisms (AI) and (A2) will be explained.

A first drag mechanism (A1) provided at the spool side end of the input shaft (1) is a first drag mechanism (A1) that rotates in conjunction with the input shaft (1).
A second rotor is interposed between the input side rotary body (4) and the output side rotary body (5) and is provided at the handle side end of the input shaft (1).
The drag mechanism (A2) is interposed between the second input end rotary body (12) and the output side rotary body (5), which rotate in conjunction with the input shaft (1).

The spool side inner end surface of the output rotating body (5) is in contact with the drag body (11) of the first drag mechanism (AI),
A contact plate (
5a) is fixed.

The second input end rotary body (12) is attached to the input shaft (1) with a modified cross-sectional structure or the like so that it cannot rotate relative to the input shaft (12) and is slidable in the axial direction. And the second drag mechanism (
A2) is the second input end rotating body (12) and the contact plate (
5a) with a friction plate (13) interposed therebetween.

The first input end rotating body (4) is externally fitted onto the input shaft (1) with an irregular cross-sectional structure or the like so that it cannot rotate relative to the outside, and can be pulled out to the spool side by the flange portion (1a) of the input shaft (1). The stop is prevented.

In addition, the two protruding tips (5b) formed on the inner end surface of the output rotating body (5) are inserted and fitted into the notch (llb) (see Fig. 4) of the drag body (11). , the output side rotating body (5) and the drag body (11) are configured to rotate together. Then, the first drag mechanism (A1
) is the first input end rotating body (4) and the drag body (
11), a pressure contact plate (4a) that rotates integrally with the first input side rotating body (4), and the drag body (11).
It is composed of a pressure contact plate (lla) that rotates integrally with the motor, and three friction plates (24) arranged in close contact with each other.

A plurality of disk springs (15) are interposed between the second input end rotating body (12) and an adjusting tool (14) screwed onto the threaded portion of the outer end of the input shaft (1). The first drag mechanism (A1) and the second drag mechanism (A2) are brought into pressure contact with each other by the biasing force of the disc spring (15), and the pressure contact force (drag force) is controlled by the adjustment tool ( It can be adjusted by the rotation operation of 14).

The clutch mechanism (B) for speed change includes an output side rotating body (5
) and the base portion (6a) of the high-speed output gear (6).Next, this clutch mechanism (B) for speed change will be explained.

As shown in FIG. 4, a recess (6C) is formed on the inner periphery of the base portion (6a) of the high-speed output gear (6), and a raised pawl (6C) that can be engaged with the recess (6c) Two approximately semicircular lock pins (16) having claws (16a) are inserted between the output rotating body (5) and the input shaft (1).
The lock pin (1
A shaft pin (17) that is relatively rotatably engaged with a groove (16b) formed on the inner circumference of the input shaft (1) is passed through an axially long slit (1b) formed on the input shaft (1). The claw (16a) of the lock pin (16) is connected to the output rotating body (5).
It passes through a cut groove (5a) formed on the spool side of the lock pin (16), so that the lock pin (16) always rotates integrally with the output side rotating body (5) regardless of the position change due to its sliding movement. It has become.

A holder (18) that supports a shaft pin (17) is fitted inside the input shaft (1) so as to be slidable in the axial direction. This holder (18) has a return spring (19)
is always biased toward the handle. Further, a pushing shaft (20) for pushing the holder (18) toward the spool is inserted, and this pushing shaft (20) is used to prevent the nozzle member (IOA) from being removed. It protrudes through the center hole of the lid (21).

In other words, when the push shaft (20) is pushed toward the spool side, the holder (18) and shaft pin (17
), the lock pin (16) slides toward the spool side, and its claw (16a) and the base part of the high-speed output gear (6) (
A low speed transmission state is entered in which the engagement with 6a) is released. Then, when the pushing force of the pushing shaft (20) is released, the first
As shown in the figure, the holder (18) moves toward the /S handle side by the action of the return spring (19), and the lock pin (16) and the base part (6a) of the high-speed output gear (6)
) enters a high-speed transmission state where they mesh and engage.

As shown in FIG. 1, the handle member (IOA) is provided with a locking piece (22) that maintains the pushed-in state of the push-in shaft (20). This locking piece (22) is supported so as to be able to slide along the longitudinal direction of the handle member (IOA), and is constantly urged toward the opposite side of the push shaft by a pressing spring (23). In addition, the locking piece (
The push shaft side end of 22) has a shape that surrounds the push shaft (20), and extends toward the side opposite to the push shaft with respect to the circumferential recess (2OA) formed at the exposed tip of the push shaft (20). It is formed so that it can be engaged by movement of.

Therefore, when the push-in shaft (20) is pushed in, the locking piece (22) is constantly pushed by the push spring (23).
automatically bites into the circumferential recess (20A) and pushes the shaft (2
0) is maintained in the pushed state, thereby maintaining the low speed transmission state (see Fig. 2).

When the locking piece (22) is pressed and moved toward the shaft side, the locking piece (22) and the circumferential recess (20A) are disengaged, and
Push shaft (20) by return spring (19)
) moves toward the handle and returns to the high-speed transmission state (see Figure 1). In other words, the transmission mechanism (C) of this reel
This operation is performed by pushing the push-in shaft (20) and the locking piece (22).

As shown in FIG. 5, the uneven part (4b) formed on the outer periphery of the first input end rotary body (4) and the swinging claw (34) supported on the -reel case (25) side allow for one-way rotation. A clutch-type stopper mechanism (E) is configured to prevent the input shaft (1) from rotating in the opposite direction in the line payout direction.

In addition, (36) connects the swinging claw (34) to the input side rotating body (4).
This is a tension spring that urges it to swing to the side.

Next, the clutch mechanism (D) will be explained.

As shown in Figure 1, the output shaft (3) is connected to the spool shaft (2).
A), and is configured to rotate integrally with the spool shaft (2A) by meshing with the irregular cross-sectional structure at its spool side tip. A shift fork (26) that engages with a recess (3A) formed on the outer periphery of the output shaft (3) is provided, and the shift fork (26) moves the output shaft (3) to turn the clutch on and off. It is now possible to do so. In other words, by moving the output shaft (3) toward the spool side, the output shaft (3) and the spool shaft (2A) become in a clutch engaged state where they mesh and engage, and the output shaft (3) is moved toward the handle. As a result, the clutch is disengaged and the clutch is disengaged.

As shown in FIGS. 5 and 6, the shift fork (
26) is a substantially half-shape whose both ends are fitted into the support shafts (27), (27) so as to be slidable in the axial direction, and which engage with the recess (3A) formed on the circumference of the output shaft (3). Circular retaining part (2
6A), and further includes a return spring (30), (
30) to return to the spool side. The shift fork (26) supported in this way is connected to the output shaft (
The sliding plate (29) is moved by the raised portions (29a), (29a) of the sliding plate (29), which is slid in a direction perpendicular to the axial direction of the sliding plate (3).
29) is adapted to be moved by a rotation operation section (28) arranged so as to protrude outside the reel case (25). That is, the pin (28a) attached to the rotation operation part (28) is inserted into the elongated hole (29b) of the sliding plate (29).
), and when the rotation operation part (28) is rotated from the state shown in FIG. 5 to the state shown in FIG. 6, the sliding plate (29) moves toward the output shaft, The raised part (29a)
.

(29a) pushes the shift fork (26) toward the handle, and as a result, the output shaft (3) slides toward the handle and becomes uncoupled from the spool shaft (2A), releasing the clutch. It becomes.

Then, when the rotation operation part (28) is returned to the state shown in Fig. 5,
As the sliding plate (29) moves toward the side opposite to the output shaft, the shift fork (26) moves toward the spool by the return springs (30), (30), and as a result, the output shaft (3) moves toward the spool. It moves and engages with the spool shaft (2A) to engage the clutch.

The rotation operating member (28) is held in both the clutch engaged and disengaged states by the biasing force of one torsion spring (35).

Here, as mentioned above, the low speed output gear (7) and the low speed input gear (9) are formed into helical gears, and the high speed output gear (6) is formed into a helical gear.
) and the reason why the high-speed input gear (8) is formed into a straight gear will be briefly explained.

If the low-speed output gear (7) and low-speed input gear (9) are formed into helical gears, when a rotational force is applied to the spool (2) in the line payout direction, especially when a drag is applied, This is effective in preventing the output shaft (3) from moving toward the clutch disengagement side. And high-speed output gear (6)
By forming the high-speed manual gear (8) as a straight gear, the following advantages are obtained compared to forming the high-speed output gear (6) and the high-speed input gear (8) as helical gears. It has become. In other words, if the high-speed output gear (6) and the high-speed input gear (8) are formed as helical gears, when a rotational force in the line payout direction is applied to the spool (2) in a high-speed shifting state, the high-speed output gear ( 6) is the low speed output gear (
7) side, both gears (6) and (7) are pressed against each other, and as a result, the relative rotation of both gears (6) and (7) is inhibited, and as a result, the steering wheel rotation force increases. However, forming the high-speed output gear (6) and the high-speed manual gear (8) as straight gears may cause the disadvantage that the contact surfaces of both gears (6) and (7) will wear out quickly. This avoids such disadvantages.

This reel also has a spool shaft (2
A braking mechanism (F) is provided to provide light rotational resistance to A). This is composed of a structure in which a brake body (31) that is threadedly engaged with the reel case (25) is pressed against the end surface of the handle side of the spool shaft (2A), and by rotating the brake body (31), the resistance can be increased. This allows you to adjust the settings.

The light resistance force produced by the braking mechanism (F) prevents the spool (2) from rotating too much due to inertia when the clutch mechanism (D) is disengaged and the fishing line is cast.

[Another example]

The present invention can be applied to reels of types other than the double-bearing type, and may be implemented in a form in which the number of gears is three or more.

In the above embodiment, a reel that is rotated by a handle (10) has been described, but the present invention can also be applied to a reel that is rotated by an electric motor.

In the above embodiment, a pair of drag mechanisms (Al), (A2
), but it may be implemented, for example, in a form in which only the first drag mechanism (At) described in the above embodiment is provided. In this case, for example, in the above embodiment, a thrust bearing, a washer, or the like may be interposed between the second input end rotating body (12) and the abutting plate (5a).

Furthermore, although the transmission mechanism (C) was configured using a spur gear type gear in the above embodiment, it is necessary to configure the transmission mechanism (C) using a bevel gear type gear to carry out the present invention. The specific configuration of each part can be changed in various ways depending on the intended use.

Incidentally, although reference numerals are written in the claims section for convenience of reference to the drawings, the present invention is not limited to the structure shown in the accompanying drawings by such entry.
