Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reciprocating twilling groove mechanism incorporated in a parallel winding device for a fishing reel. More specifically, the present invention relates to an improvement in the structure related to the operational performance of this twilling groove mechanism for reciprocating motion.

[Prior Art] Conventionally, a twill groove mechanism for reciprocating motion has, for example, a twill groove that is spirally carved in opposite directions in the axial direction and communicated at both ends, and is rotated about an axis. A shaft, a slider having a sliding pawl that slides in the twill groove of the twill shaft, and a slider holder that rotatably accommodates the slider and is movable in the axial direction of the twill shaft and fitted in a non-rotatable manner. It is known that the slider holder is reciprocated in the axial direction of the twill shaft by the rotation of the twill shaft.

According to this conventional twill groove mechanism for reciprocating motion, the sliding pawl of the slider slides in the twill groove at a certain angle inclined to the axis of the twill shaft, and the slider slides at both ends of the twill groove. The sliding pawl of the slider is perpendicular to the axis of the twill shaft, and then the sliding pawl of the slider slides in the twill groove at a certain angle inclined in the opposite direction to the axis of the twill shaft. become.

[Problems to be solved by the invention] In the conventional twill groove mechanism for reciprocating motion described above, in order to improve the slidability of the sliding pawl of the slider within the twill groove,
Since the width of the twill groove is wider than the width of the sliding pawl of the slider, the inclination angle of the sliding pawl of the slider that slides in the twill groove becomes unstable, making it difficult for the slider holder to move back and forth. It has the problem of being unstable.

The present invention was made to solve these problems, and its purpose is to provide a twilling groove mechanism for reciprocating motion that stabilizes the reciprocating movement of the slider holder.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the twill groove mechanism for reciprocating motion according to the present invention includes twill grooves that are spirally carved in opposite directions in the axial direction and communicated at both ends. a twill shaft that rotates around its axis, a slider having a sliding pawl that slides in the twill groove of the twill shaft, and a slider that rotatably accommodates the slider and moves in the axial direction of the twill shaft. In a twilling mechanism for reciprocating motion comprising a slider holder that is movable and non-rotatably fitted, the sliding claw of the slider is inclined with respect to the axis of the twill shaft in the twill groove during the reciprocating movement of the slider holder. A means is adopted which is characterized by comprising a holding member that holds the respective angles constant and allows change of the inclination angle at both ends of the twill groove.

[Operation] According to the above-mentioned means, since the inclination angle of the sliding claw of the slider is held by the holding member, the inclination angle of the sliding claw of the slider does not fluctuate.
The purpose of stabilizing the reciprocating movement of the slide holder is achieved.

[Example] Hereinafter, an example of the twill groove mechanism for reciprocating motion according to the present invention will be described based on the drawings.

1 to 3 show a first embodiment of a twilling groove mechanism for reciprocating motion according to the present invention.

In this embodiment, as is clear from FIG.
It is shown incorporated into a parallel winding device for a fishing reel.

The fishing reel of this embodiment has left and right side frames 1 and 2.
A handle 4 attached to one side frame 1 rotates a spool 3 supported between the two sides. Furthermore, for such a configuration,
A twill shaft 5 supported parallel to the spool 3 is provided between the left and right side frames 1 and 2, and this twill shaft 5 is also driven to rotate about its axis by the handle 4. It's summery.

The twill shaft 5 has two twill grooves 51 and 52 spirally carved in opposite directions in the axial direction, and these twill grooves 51 and 52 are connected at both ends to form an endless shape. It is becoming. In addition, Ayamizo 5
1 and 52 are arranged perpendicularly to the axis of the twill shaft 5.

For such a twill shaft 5, the slider 6 is
are linked. The slider 6 has the twill grooves 51 and 52.
An arc-shaped sliding claw 61 that engages and slides inside, and a cylindrical base 6 that has this sliding claw 61 on one end surface.
It consists of 2. This slider 6 is housed in a cylindrical slider holder 7 such that its base 62 is rotatable.

This slider holder 7 has a cylindrical main body 71 that rotatably accommodates the base 62 of the slider 6, a cap 72 for storing and assembling the slider 6, and a guide hole 73 through which a thread is inserted. have. Further, the slider holder 7 engages and fits into the twill shaft 5 and the guide plate 8 provided along the same, and is movable in the axial direction of the twill shaft 5 but cannot rotate. .

Furthermore, a holding member 9 is constructed between the slider 6 and the slider holder 7. This holding member 9 consists of a locking piece 91 provided on the end surface of the base 62 on the opposite side of the sliding claw 61 of the slider 6, and two magnets attached to the inner surface of the slider holder 7 so as to face each other. It consists of 92 and 93. This locking piece 9
1 is arranged on the same line as the sliding claw 61 of the slider 6. Further, the magnets 92 and 93 are formed in an arcuate shape, and one end surface of each magnet attracts the locking piece 91 to hold the locking piece 91 at a constant angle. In addition, this magnet 9
2 and 93 are arranged so that the line serving as the center of symmetry between them is perpendicular to the axis of the twill shaft 5.

According to such an embodiment, as the twill shaft 5 is rotated, the sliding pawl 61 of the slider 6 slides within the twill groove 51 in one direction of the twill shaft 5 at a constant inclination angle. Therefore, the slider holder 7 housing the slider 6 moves in one direction in the axial direction of the twill shaft 5, and when the sliding pawl 61 of the slider 6 reaches the communication part, its inclination angle changes to the twill direction. The twill groove 5 is perpendicular to the axis of the groove shaft 5, and the sliding claw 61 of the slider 6 is in the opposite direction.
2 at a constant inclination angle, the slider holder 7 moves in the opposite axial direction of the twill shaft 5.

In such movement of the slider holder 7, the threads inserted into the guide holes 73 of the slider holder 7 move as follows.
It is evenly supplied in the axial direction of the twill shaft 5 of the slider holder 7, that is, in the axial direction of the spool 3, and is evenly wound onto the spool 3.

In addition, in such movement of the slider holder 7, when the sliding pawl 61 of the slider 6 slides within the twill grooves 51, 52 of the twill shaft 5, that is, the sliding pawl 61 slides inside the twill groove shaft 5. If the locking piece 91 has a certain inclination angle with respect to the axis of the sliding claw 61, the locking piece 91 located on the same line as the sliding claw 61 will be attracted and held by the magnets 92 and 93. Furthermore, when the sliding pawl 61 of the slider 6 reaches the communication portion 53 of the twill grooves 51 and 52 of the twill shaft 5, the locking piece 91 is pulled away from the magnets 92 and 93 against the attraction force of the magnets 92 and 93. As the sliding claws 61 are further slid into the traverse grooves 51 and 52 in the opposite direction, the locking pieces 91 are held tilted in the opposite direction.

Therefore, the inclination angle of the sliding pawl 61 of the slider 6 sliding in the twill grooves 51, 52 of the twill shaft 5 is always kept constant and does not wobble.

FIGS. 4 and 5 show a second embodiment of the twilling groove mechanism for reciprocating motion according to the present invention.

In this embodiment, the magnet 9 of the first embodiment is
This is a modification of the ball 94 and the spring 95 so that the function of 2 and 93 can be performed.

This ball 94 is rotatably fitted into a groove 71' cut out in the peripheral wall of the cylindrical main body 71 of the slider holder 7, and a part of the ball 94 projects into the main body 71. In addition, a slider holder 7 with a groove 71' cut out
A leaf spring 95 is wound around the outside of the cylindrical main body 71 to bias the ball 94 inward in the radial direction.
The locking piece 91 of the slider 6 fitted inside the slider 1 is brought into contact with a protrusion 91' formed protruding on the outer circumferential surface of the locking piece 91.

With the above configuration, direction change is performed at the communication portions at both ends of the twill grooves 51 and 52, and when the slider 6 is reversed at this communication portion, the locking piece 91 protrudes near the neutral point of the communication portion. The portion 91' pushes the ball 94 outward in the radial direction against the elastic force of the leaf spring 95, and even after passing through the neutral point and reversing, the ball 94 is pushed out by the elastic force of the leaf spring 95 in a part of the convex portion 91'. As a result, a rotational force always acts on the slider 6 in one direction (in the case of FIG. 5, the rotational force is counterclockwise), and the sliding claw of the slider is rotated. The inclination angle of the twill shaft in the twill groove relative to the axis is maintained in a constant direction. Incidentally, since a rotational force acts on the slider through the ball, and the rotational force directs the slider, the ball, the protrusion of the locking piece, and the sliding pawl and protrusion on the slider are It is necessary to adjust the positional relationship.

As described above, in addition to the illustrated embodiment, the holding member 9 is connected to the peripheral surface of the base 62 of the slider 6 and the main body 71 of the slider holder 7.
It is also possible to provide an embodiment in which it is configured between the inner circumferential surface of the

[Effects of the invention] As described above, in the twill groove mechanism for reciprocating motion according to the invention, since the inclination angle of the sliding pawl of the slider is held by the holding member, fluctuation of this inclination angle is prevented. This has the effect of stabilizing the reciprocating movement of the slider holder.

Further, due to this effect, when applied to a fishing reel, the operability of the fishing reel is improved.
