Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fishing reel, and a mechanical structure for stopping the delivery of a line when the line is delivered to an arbitrary preset depth. Regarding

[Conventional technology]

Generally, fish live in different depths depending on various conditions such as their type and season, but when fishing is carried out using reels, if the fish rack is found, the fish hooks should be sunk to the same depth to obtain the fishing results. Get higher

Conventionally, various configurations have been devised that allow this action to be performed on the reel itself without the need for a human being to take the action. For example, the number of revolutions of the spool at the time when it reaches the fish shelf and the amount of feeding of the thread itself are stored in a numerical value on the reel unit, and after winding the thread, it is reeled out again to reach the set value. For example, a configuration in which a solenoid or a plunger is driven to forcibly stop the rotation of the spool is used.

[Problems to be solved by the device]

In the case of the above-mentioned conventional example, once the depth of the fish rack is set, the spool rotation is always stopped at the same depth no matter how many times the line is extended thereafter, which is convenient. However, even when the line is extended to a position deeper than the set fish rack, the line is always stopped at the set depth, so the operation is very troublesome when searching for a deep fish rack without changing the set depth.

Also, in the conventional example, the spool is stopped by a solenoid or a plunger, and there are many electrical configurations.However, for reels exposed to seawater, rain, etc., complete waterproofing is required to avoid failures due to leaks or short circuits. There is a problem that the manufacturing cost rises because it needs to be applied.

The present invention is intended to solve these problems, and it is possible to arbitrarily select whether or not to stop the delivery of a road thread at a set depth, and a road for fishing reels that uses many mechanical structures and has few failures. An object is to provide a yarn feeding stop mechanism.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention has a propeller that rotates in conjunction with a motor, and a lock portion having a shape corresponding to one unit of a spool gear directly connected to a spool,
The spool is stopped by engaging this lock part with the spool gear and the set state separated from the spool gear, and the spool is stopped in response to the spool stop cam and the control lever. A reset cam that returns the cam to the set state, a locking cam that has a locking piece that contacts the spool stop cam that is in the set state and holds it in the set state, and a pivot cam that is pivotally supported by the locking cam to move the propeller A trigger cam that transmits to the locking cam to release the above holding function of the locking piece, and, in response to an operation, extends the trigger cam from an inoperative position where it cannot contact the propeller to an operating position where it can contact the propeller, and a control lever And a switching mechanism for returning the trigger cam to the inoperative position in response to the above.

[Action]

When you operate the control lever, the reset cam returns the spool stop cam to the set state, and
The switching mechanism returns the trigger cam to the inoperative position where it cannot contact the propeller. In this state, the trigger cam cannot come into contact with the propeller, so the stop mechanism does not operate.

When the switching mechanism is operated in this state and the trigger cam is extended to the operating position where it can contact the propeller, the trigger cam can contact the propeller, so that the stop mechanism operates. That is, when the propeller rotates, the trigger cam transmits the movement of the propeller to the locking cam to release the holding function of the locking piece, so that the spool stop cam changes from the set state to the stopped state, and the spool gear stops.

〔Example〕

An embodiment of the present invention will be described in more detail below with reference to the drawings. Reference numeral 1 is a propeller that rotates in unison when the motor rotates. Reference numeral 2 is a trigger cam, which is pivotally supported at 2a with respect to the locking cam 3 described below, and is secondly centered around this shaft center 2a.
In the figure, it is biased counterclockwise by a spring. The trigger cam 2 has an operating position where it can contact the propeller 1 as shown in FIG. 2 and an inoperative position where it cannot contact the propeller 1 as shown in FIG. 4, and when it is in the operating position. , A function of transmitting the movement of the propeller 1 to the locking cam 3 and holding the locking piece 4 below (to the engaging portion 6 of the spool stop cam 5 below when the locking piece 4 is in the set state as shown in FIG. 2). The function of holding the set state by abutting) is released. Reference numeral 3 denotes a locking cam that interlocks with the trigger cam 2, and integrally includes a locking piece 4 that abuts on an engaging portion 6 of the spool stop cam 5 in the set state as shown in FIG. Reference numeral 5 denotes a spool stop cam, which has an engaging portion 6 that engages with the locking piece 4 and a lock portion 8 having a shape corresponding to one tooth shape unit of the spool gear 7, and as shown in FIG. It takes a stopped state in which the lock portion 8 is engaged with the spool gear 7 and a set state in which the lock portion 8 is separated from the spool gear 7 as shown in FIG. 2, and constantly rotates around the shaft 11 from the set state to the stopped state. Is urged by a spring. Also, 9
Is a spool directly connected to the spool gear 7. A reset cam 10 is rotatably provided by operating a control lever (not shown) and returns the spool stop cam 5 to the set state.

Here, 12 is a restricting piece of the locking cam 3, which restricts the spool stop cam 5 from rotating too much when the engaging piece 4 and the engaging portion 6 are disengaged.

Next, the operation of the present embodiment will be described step by step. In the case of delivering the yarn, the spool 9 is freely rotated in the set state shown in FIGS. 2 and 3, and the yarn is pulled out by the gravity of the weight. Go on. Subsequently, the number of rotations of the spool or the amount of the line thread fed out is calculated by a sensor / CPU, and when a preset depth (numerical value) is reached, the motor is rotated by a switch. Then, the propeller 1 rotates in the direction of arrow A in association with the rotation of the motor, contacts the obliquely cut contact surface 2b of the trigger cam 2 located in the rotation range, and the contact slip causes the trigger cam 2 to move in the direction of arrow B. Push. As a result, the locking cam 3 also interlocks and rotates in the direction of arrow C, and the engagement between the locking piece 4 and the engaging portion 6 is released. The arrow B direction and the arrow C direction are movements about the rotation center 3a of the locking cam 3. Then, the spool stop cam 5 rotates in the biasing direction D of the spring, and the lock portion 8 and the spool gear 7 are brought into mesh with each other as shown in FIG. 1 to be in a stopped state, whereby the rotation of the spool 9 is forced. To stop. In this case, the engaging portion 6 of the spool stop cam 5 abuts against the restricting piece 12 to prevent excessive rotation. When the reset cam 10 is rotated by the control lever in such a forced stop state, the spool stop cam 5 returns as shown in FIG. 4, and the locking piece 4 biased in the engaging direction is released. It can be engaged with the engaging portion 6 and can be set again.

In addition, the shape of the lock portion 8 does not only correspond to the valley of the lock gear 7, but if the valley and the peak are formed as a unit and corresponding to this, the biting of the lock portion 8 occurs at the peak portion. Being regulated, you can make an appropriate stop.

As described above, the rotation of the spool 9 is forcibly stopped when the yarn is fed up to the set value. However, for example, when this mechanism is adopted for a manual fishing reel or when a dedicated motor is installed, there is no problem, but when the driving motor is shared with the motor of this mechanism in the electric reel, If the motor is driven at the time of winding the road yarn, the same operation as described above is performed, and the rotation of the spool stops at the same time as the winding. In order to eliminate this, a switching mechanism S is provided in this embodiment. In response to the operation of the push button 17 described below, the switching mechanism S moves the trigger cam 2 from the inoperative position where it cannot contact the propeller 1 as shown in FIGS. Three
As shown in the figure, when the control lever is extended to the operating position where it can contact the propeller 1, and when the control lever is activated, the trigger cam 2 is returned to the inoperative position.

The specific structure of the switching mechanism S is as follows:
A mechanism as shown in FIG. 3 is provided, which is integrally provided with a push-up piece 13 and is provided with a push-up claw 14 that abuts against the push-up piece 13 and pushes it up. That is, 15 is a lock cam that rotates around 15c, and the lock cam 15 has a push-up claw 14
Are integrally provided, and the push-up claw 14 is in contact with the push-up piece 13 from below through the through hole 16. A push button 17 is provided so as to be able to project to the outside of the reel unit.
Further, the tip end 15a of the lock cam 15 is bent in a hook shape, while the tip end 17a of the push button 17 is formed to project toward the front perpendicular to the paper surface of FIG. Also, lock cam 15
Is biased by a spring 15b so as to rotate in the direction of arrow E, and the push button 17 is also projected by the spring (upward direction in FIG. 3).
Is urged by. Therefore, in the state shown in FIG. 3 in which the push button 17 is pushed in, the tip end 17a of the push button 17 is engaged with the tip end 15a of the lock cam 15. Reference numeral 21 is provided coaxially with the reset cam 10, and an interlocking gear that rotates integrally with the reset cam 10, 20 is an interlocking gear that meshes with the reset cam 10, and 19 is an upper half of the outer periphery that meshes with the interlocking gear 20 and has an outer periphery. The reset gear 19 has a recessed portion in the lower half portion, and the reset gear 19 is rotated by the operation of the control lever. Reference numeral 18 denotes a reset arm that rotates about 18b, one side rotation end 18a of which is engaged in a recessed portion of the reset gear 19 and the other side rotation end 18c is in contact with one end of the lock cam 15 from below. . Therefore, when the reset gear 18 is rotated by the control lever, the interlocking gears 20 and 21 are sequentially rotated in the arrow direction, the reset cam 10 is rotated, and the spool stop cam 5 is returned to the set state. The one end rotating end 18a of the reset arm 18 is pushed by the end surface 19a of the recessed portion of the reset gear 19, the reset arm 18 rotates in the direction of arrow F, and the other end rotating end 18c of the reset arm 18 locks the lock cam 1
Push one end of 5 up in the direction opposite to arrow E, and
When this is pushed up, the push-up piece 13 is pushed up by this, so that only the trigger cam 2 pivots clockwise from the operating position in FIG. 2 to the inactive position in FIG. 4, and the propeller 1 contacts the trigger cam 2. It cannot contact the surface 2b. Moreover, the rotation of the lock cam 15 causes the lock cam tip 15a to move.
Is released from the push button tip 17a, and the push button 17 returns to the protruding state.

With this configuration, when it is desired to exert the stopping function of the stopping mechanism such as when the road yarn is being fed out, the push button 17 is pushed in from the state of FIG. 4 to move the trigger cam 2 to the operating position. In the set state shown in FIG. 3 and FIG. 3, the lock cam 15 moves in the direction of the arrow E by the spring force, the push-up claw 14 does not push up the push-up piece 13, and the set state is maintained, so that the propeller 1 rotates. In response to this, the stop mechanism becomes operable, and when the stop mechanism operates, it becomes the stop state as shown in FIG. On the other hand, when the reset gear 18 is rotated by the control lever when winding the road thread, the trigger cam 2 returns to the inoperative position as shown in FIGS. 4 and 5, and the propeller 1 is operated by the above-described operation. Since it does not come into contact with the contact surface 2b of the trigger cam 2, even when the motor is driven to wind up the yarn,
Since the interlocking relationship of each mechanism is broken, the rotation of the spool does not stop unless the push button 17 is pressed.

[Effect of device]

Since the present invention is configured as described above, the rotation of the spool while the line is being fed can be reliably stopped and the return of the spool can be stopped by the control lever by simply rotating the motor for a moment at the set depth. It can be done by operation, and reel operation during fishing became easier.

Also, except for the control part of the motor, everything is mechanically structured, so waterproofing is completed simply by protecting the rotating part with grease, and it is no longer necessary to provide complete waterproofing as in the past, reducing manufacturing costs. It became possible to do.

Further, since it is possible to select whether or not the spool can be stopped while the line thread is being fed out by one operation of the switching mechanism, even when it is desired to feed the line thread to a deeper position beyond the set depth, it is temporarily stopped midway. Thus, it is possible to provide a road line feeding stop mechanism that has a great effect such that the troublesomeness can be avoided, and the complicated operation during fishing as in the case of using the conventional example can be eliminated.
