Description

[Detailed Description of the Invention] This invention relates to a drag-free position adjustment mechanism for a reel equipped with a handle-type drag mechanism.

In order to operate the drag of a fishing reel, especially a double bearing reel, the drag knob is normally operated by rotating a star-shaped or dial-shaped drag knob, but there is a handle attached to the drag knob. There are some that replace the arm and allow you to adjust the strength or weakness of the drag or force the drag just by operating the handle.

That is, you can weaken the drag force by rotating (loosening) the handle in the opposite direction to the fishing line winding direction, or
The handle can be rotated and tightened in the winding direction to increase the drag force, and the handle can also be rotated in the direction to tighten more strongly to create a forced winding state.

The drag action described above is performed within a certain rotation angle of the handle.

However, since the drag device described above is constructed by stacking multiple drag washers, arcuate springs, drag sleeves, and various other parts, the drag force may vary due to variations in the thickness and length of each part. There is a problem that is not constant.

The present invention was devised in view of the above-mentioned circumstances, and it is possible to reduce the variation in drag force caused by variation in the various parts that make up the drag device by changing the set position of the parts that regulate the rotation range of the handle. As a result, a drag-free state can be created and a desired drag range can be created.

The adjustment mechanism of the present invention that achieves this purpose includes a slot in the upper part of the main gear shaft that protrudes from the handle surface to form an engagement shaft portion with an oval cross section. A stop boss having a hole is fitted and engaged, and a stop plate with arms protruding from appropriate locations on the outer periphery is fitted on the outside of the stop boss, and a stop pin is provided on the handle surface to abut against the arm of the stop plate. The main point is that it has been firmly established.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a drive mechanism operated by the rotation of a handle, in which a main gear shaft 3 is attached to a core shaft 2 that is erected and fixed to a base plate 1. The main gear 4 is fitted to the main gear shaft 3 so that it can rotate freely, and a screw is carved on the upper half circumference of the main gear shaft 3. A drag metal 6 formed into a shape and integrated with the handle 5 is screwed.

Also, between the drag metal 6 of the handle 5 and the main gear 4, there are a drag washer 7, a drag plate 8, a washer 9, and a coil spring 1.
A drag device consisting of 0 is interposed, and the handle 5
When the handle 5 is tightened, the drag force becomes strong, and when the handle 5 is loosened, the drag force becomes weak.

That is, when the handle 5 is tightened, the drag metal 6 clamps and presses the main gear 4 with the drag washer 7 via the coil spring 10 and the drag plate 8, and a strong drag force acts on the reverse rotation of the main gear 4, and the handle 5 During forward rotation, the main gear 4 also rotates together with the drag force.

The outer peripheral surface of the main gear shaft 3 protruding outward from the handle 5 is slotted to form an engagement shaft portion 11 having an oval cross section.
A stop boss 12 is fitted on the stop boss 1, and a stop plate 13 is fitted on the outside of the stop boss 12 and fastened with a locking nut 14. The stop boss 21 has a cross-shaped oval hole 27 that matches the engagement shaft 11 in the center thereof, and a protruding piece 22 protrudes from the outer peripheral surface.
The stop plate 23 that fits into the stop boss 2
A circular hole 24 into which 1 is inserted is opened, and
Around the circular hole 24 is a recess 25 into which the protrusion 22 fits.
is cut out within a certain range (the drawing shows a case of approximately 90°).

Therefore, the rotational range of the handle 5 is such that the handle 5 rotates once and the stop pin 18 reaches the stop plate 2.
In addition to the range where it collides with the arm 26 of No. 3, the drag can be rotated by the range of the recess 25 formed in the stop plate 23, and the tightening force of the drag is applied by the range of the recess 25 in which the stop plate 23 rotates. Only this will be further strengthened.

If the desired drag strength cannot be obtained in the set state shown in the figure, remove the nut 14 and shift the fitting position between the stop boss 21 and the main gear shaft 3 by 90° or 180° in the reverse direction. The amount of rotation of the handle 5 in the reverse direction is increased, and the range of weak drag can be expanded.

Incidentally, if it is desired that the amount of rotation of the handle 5 in the forward rotation direction be close to two rotations, the opening angle of the recess 25 of the stop plate 23 may be increased. (Refer to Figures 5 to 7) The drag-free position adjustment mechanism of the present invention has a stop boss fitted to a main gear shaft having an oval cross section, and a stop plate fitted to the stop boss so that the fitting position can be freely adjusted. However, since the stop plate has a protruding arm that abuts against the stop pin on the handle, the handle can be adjusted by changing the fitting position of the stop boss with respect to the main gear shaft and the fitting position of the stop plate with respect to the stop boss. The rotation range can be increased or decreased.

Therefore, the drag force may be insufficient in the strong/weak direction in the preset state, or variations in the drag force may occur due to variations in wall thickness, length, etc. of the parts that make up the drag device. The attachment can be easily adjusted by changing the stop boss and stop plate settings.

Therefore, it is possible to obtain the optimum drag force depending on the fishing.

Claims (1)

[Scope of utility model registration request] A handle is screwed onto the main gear shaft which holds the main gear freely and can be tightened and loosened, and a drag device is interposed between the handle and the main gear, so that when the handle is tightened, the main gear rotates integrally. In a fishing reel equipped with a handle-type drag mechanism in which the main gear slips when the handle is loosened, a slit is made in the upper part of the main gear shaft that protrudes from the handle surface, and the engagement has a non-circular cross section. A shaft is formed, and a plurality of holes having the same shape as the shaft are fitted into the engagement shaft, and stop bosses are drilled at the same center and at different phases in the circumferential direction. A protruding piece is provided on the outer periphery, an arm is protruded from the outside of the stop boss at appropriate locations on the outer periphery, and a stop plate with a recess cut out into which the protruding piece is fitted is fitted around the circular hole, and a stop plate is fitted on the handle surface. It has a drag-free position adjustment mechanism with a fixed stop pin that abuts against the arm of the stop plate.
