Description

[Detailed Description of the Invention] This invention relates to a reversal prevention device for a fishing reel, and more particularly to a reversal prevention device for a fishing reel that can be used for both right-handed and left-handed winding.

The handles for this type of fishing reel include those for right-handed and left-handed reeling, as well as handles for both right-handed and left-handed reeling.

The direction of rotation of the handle on this reel for both right-handed and left-handed winding is completely opposite when winding with the right hand and when winding with the left hand, so the reversal prevention device must also be changed according to the switching of the winding hand. Must be.

By the way, as a conventional reversal prevention device for this type of fishing reel, there is Japanese Utility Model Publication No. 52-6631. In this device, a pair of pawl pieces that engage with a ratchet wheel are provided on the inside of the side plate, and an operating lever provided on a cam that engages with the operating portion of the pair of pawl pieces is pivoted on the side plate. Long and short stopper screws are removably installed in the parts corresponding to the left and right regulating positions of the operating lever, and the swing range of the operating lever is regulated by replacing the long and short stopper screws.
This allows the claws operated by the cam to change.

However, the above structure restricts the swinging range of the operating lever by regulating the swinging range of the cam, and changes the engagement and disengagement of the pawl with the actuating part. If the integration between the shaft and the cam is impaired, the movement of the operating lever and the movement of the cam become inconsistent, resulting in problems such as the inability to properly operate the pawl piece.

Therefore, the present invention has been developed to solve the above-mentioned problems, and has a pair of left and right non-return claws that are pivotally supported within the side plate, which are held in an operable and inoperable state by long and short stopper screws. This makes it possible to establish stable operation.

The reversal prevention device of the present invention that achieves this purpose is
A pair of left and right non-return claws that engage and disengage from a non-return gear fixed to the handle rotation shaft are supported pivotably inside the side plate facing each other, and the claws of both non-return claws are engaged with the non-return gear by a spring. A pair of screw holes are drilled at corresponding locations on the side plate to press and bias the non-return claw in the direction of engagement, and to press the operating part of the non-return claw to maintain the claw part in a state where it cannot engage with the non-return gear. The stopper screw is removably screwed on, and the non-return pawl can be switched ON and OFF by operating a switching lever.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a handle rotation shaft provided through a side plate 2, and a main gear 3 is attached to a protruding portion of the handle rotation shaft 1 in the side plate 2. A non-return gear 4 is integrally fixed, and a pinion gear 5 that meshes with the main gear 3 is slidably attached to and detachable from a spool shaft 6' that is fixed integrally to a spool 6. A clutch device 7 engages and disengages the gear 5 and the spool shaft 6'.

A pair of non-return claws 8 and 9 are fitted onto shafts 10 and 10' projecting from the inner surface of the side plate 2 and are swingably supported on both left and right sides above the non-return gear 4 in the side plate 2. At the same time, coil springs 11 and 11' are attached to the shafts 10 and 10', and one end of the coil springs 11 and 11' is fixed to the claw portions 8' and 9' of the non-return claws 8 and 9, and the other end is fixed to the peripheral wall of the side plate 2. , this coil spring 11,1
1', the claws 8' and 9 of the non-return claws 8 and 9
9' is biased in the direction of engagement with the check gear 4.

The left and right pair of non-return pawls 8 and 9 have pawl portions 8' and 9, respectively.
On the side opposite to 9', actuating parts 8'', 9'', which are approximately inverted L-shaped from the front, are formed protrudingly, and the actuating parts 8'', 9'' are integrally operated by the swinging of a switching lever 12 provided on the outside of the side plate 2. The non-return pawls 8 and 9 are brought into contact with and disengaged from the non-return gear 4 by the rotation of the cam 13 in conjunction with the operation of the switching lever 12 by contacting the cam 13 in the side plate 2 which is in operation.

The rotation of the cam 13 caused by the operation of the switching lever 12 presses the operating portion 8'' or 9'' of the non-return pawl 8 or 9, thereby causing the pawl portion 8' or 9' to be removed from the non-return gear 4. However, the non-return claw 8,
A pair of screw holes 14 and 15 are formed through the corresponding portions of the side plate 2 that prevent the operating portions 8'' and 9'' of 9 from returning to the outside. Long and short stopper screws 16, 17 are removably screwed.

When the long stopper screw 16 screwed into the screw hole 14 or 15 is screwed to the position where the head 16' contacts the outer surface of the side plate 2, the screw thread 16'' engages the actuating part 8 of the non-return pawl 8 or 9. The length should be such that it comes into contact with the `` or 9'' side.

Also, the short stopper screw 17 has its head 17'.
When screwed to the position where it contacts the outer surface of the side plate 2, the length is such that the threaded rod portion 17'' cannot come into contact with the side surface of the operating portion 8'' or 9'' of the non-return pawl 8 or 9.

In the figure, 18 is in contact with the cam 13 and the operating lever 1
This is a stopper that restricts the swing range of 2.

Next, to explain the switching of the above-mentioned reverse rotation prevention device, FIG.
With the non-return ON position, the non-return pawl 8 is held so as to be able to swing, and the other non-return pawl 9 has its pawl 9' engaged with the non-return gear 4 by a long stopper screw 16. It is held in a state where it cannot be matched.

In the above state, when the switching lever 12 is swung to the opposite side to turn the non-return OFF state, the actuating part 8'' of the non-return pawl 8 is pushed down and inward by the cam 13, and the pawl 8' is reversed. The handle is separated from the stop gear 4 and can be rotated in both forward and reverse directions (see Figure 6). When the lever 12 is set in the non-return ON state, the non-return pawl 8 is held in a state where it cannot engage with the non-return gear 4 by the long stopper screw 16, and the non-return pawl 9 is made operable. .

To replace the long and short stopper screws 16 and 17, first remove the long and short stopper screws 16 and 17, then operate the switching stopper 12 to set the desired winding state to reverse check ON, and in that state, reverse the winding. This is done by screwing a long stopper screw 16 into the screw hole where the pawl is pressed by the cam 13, and screwing a short stopper screw 17 into the other screw hole.

Although the short stopper screw 17 does not have any effect on the non-return claws 8 or 9, the screw hole in the side plate 2 is open and the screw is inserted in order to prevent seawater, sand, dust, etc. from entering the side plate 2. wear.

As detailed above, the reversal prevention device of the present invention has the following features:
This is a long and short stopper screw that screws a pair of left and right non-return claws that are supported inside the side plate from outside the side plate, and holds one in a free state and the other in an unlatched state. can be reliably held in a free or hanging state by long and short stopper screws.

Therefore, it is possible to provide a reversal prevention device that can be expected to have a very stable switching operation.
