Description

[Detailed description of the device]

[Industrial applications]

The present invention relates to an improvement of a fishing spinning reel having a drag mechanism for applying a braking force to a spool.

[Prior art]

It is possible to immediately switch the drag mechanism in the fishing spinning reel from the drag operating state to the spool free rotating state so that a wide range of fishing can be performed.
It is known from the specification of 307 and JP-A-61-274638.

[Problems to be solved by the device]

However, in the former method, since the cylinder shaft that can be engaged and disengaged with the braking cylinder having the drag mechanism is directly slid and disengaged by the operating lever, the handle is rotated to switch from the spool free state to the drag operating state and return. In this case, when the engagement positions of the engagement hole of the cylinder shaft and the engagement portion of the braking cylinder do not match, an unreasonable force is applied to the operation lever and the engagement portion, which makes it impossible to smoothly and lightly perform the return switching operation and to operate the operation lever. Since the cylinder shaft directly presses and slides at the tip end, there are problems that the transmission efficiency is poor and the sliding operation of the operating lever cannot be performed smoothly. Further, in the latter method, the lock body is engaged with and disengaged from the ratchet teeth provided on the outer periphery of the braking cylinder having the drag mechanism by the operation lever in the radial direction. There is a problem that the durability is lowered and the switching mechanism is enlarged in the radial direction. In view of these circumstances, the present invention prevents the increase in size of the switching mechanism by smoothly and reliably engaging the cylinder shaft with the brake cylinder or the housing when switching from the spool-free state to the drag operating state. However, it is an object of the present invention to provide a switching device for a drag mechanism of a spinning reel for fishing, which is designed to improve the strength of an engaging portion.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the case of a yard lug system, the present invention provides a space between the left and right frames of a gate-shaped actuating member in which the lower end is pivotally supported at the lower part inside the reel housing and the upper end is pulled backward by a spring. A yoke is erected on the yoke, and an annular groove formed in the front part of a cylindrical shaft slidably fitted in the rear part of the spool shaft in the yoke is rotatably locked and formed on the cylindrical shaft. The joint portion is axially engaged with and disengageable from the engagement hole of the braking cylinder having the drag mechanism, and the operation piece of the operation lever pivotally supported on the rear portion of the reel housing is engaged with the upper rear side of the operation member. The operating lever is provided with a spring for distributing and urging in opposite directions.In the case of the front drag system, the lower end is pivotally supported at the lower part of the reel housing and the upper end is directed backward with the spring. A yoke is installed between the left and right frames of the towed gate-shaped actuating member, and the yoke is An engaging portion formed on the cylinder shaft while rotatably locking an annular groove formed on the front part of the cylinder shaft slidably fitted only in the axial direction on the rear part of the spool shaft having a drag mechanism at the tip end. Is engaged with an engaging hole formed at the rear end of the reel housing so as to be engageable and disengageable in the axial direction, and an operation piece of an operation lever pivotally supported at the rear portion of the reel housing is engaged with the upper rear side of the operation member. The operating lever is provided with a spring for urging the distribution in opposite directions. When the handle is rotated to switch from the spool-free state to the drag operating state, a kick portion is provided on the handle shaft on the rear surface of the drive gear and is spring-biased so that the kick portion can rotate by a predetermined angle. A body is fitted and a return piece is provided on the operation lever so as to project, and the reel housing between the return body and the return piece is biased by a spring and engages with the return piece to return by the operation of the operation lever. A return actuating member that moves in and out of the turning locus of the body is pivotally mounted, and the return lever is turned by the rotation of the drive gear so that the operating lever is returned to the position of the drag operating state through the return actuating member. Furthermore, when a braking body having click teeth is integrally fitted to a part of the outer peripheral portion of the cylinder shaft, the click pawl is engaged with the click teeth, and the braking member is brought into contact with the outer peripheral surface of the braking body in a flexible manner, A click sound can be generated during drag braking, and the spool free force or drag braking force can be finely adjusted by the contact degree of the braking member.

[Action]

According to the present invention, when the operating lever is manually rotated rearward, the operating piece tilts the operating member forward against the spring and slides the cylinder shaft forward through the yoke to brake the engaging portion. The cylinder shaft, which is disengaged from the engagement hole of the cylinder or the engagement hole of the housing and rotates integrally with the spool shaft, is rotatable and becomes a spool free rotation state. Then, from this state, the operation lever is directly returned to the front, or the drive gear is rotated by the rotation of the handle to move the operation lever through the return body, the return operating body engaging with the return body, and the return piece of the operation lever. When it is returned to the front, the operating member returns to the upright state due to the spring, and the yoke slides the cylinder shaft rearward, and its engaging portion engages with the engaging hole of the braking cylinder or the housing to drag the spool shaft. Restore the condition. However, in the drag operating state, since the click claws are engaged with the click teeth of the brake body, a click sound is generated when the spool shaft rotates in the reverse direction, and the pressure contact degree of the brake member with respect to the brake body is increased or decreased. By adjusting, the free force of the spool and the drag braking force can be finely adjusted.
