Spinning reel

A spinning reel comprising a reel body, a spool mounted forwardly of the reel body, a drag mechanism mounted on a rear end portion of the reel body for applying a braking force to rotation of a spool shaft connected to the spool, and means for adjusting the braking force of the drag mechanism D having a first control element for determining a reference braking force and a second control element for varying the braking force. The first control element defines a connected portion, and the second control element has a connecting element switchable between a position engageable with the connected portion and a position disengaged from the connected portion.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a spinning reel, and more particularly to 
a spinning reel comprising a reel body, a spool shaft connected to a spool 
mounted forwardly of the reel body, a drag mechanism mounted on a rear end 
of the reel body for applying a braking force to rotation of the spool 
shaft, and means for adjusting the braking force of the drag mechanism 
having a first control element for determining a reference braking force 
and a second control element for varying the braking force. 
2. Description of the Related Art 
An example of the spinning reel as noted above is shown in Japanese Utility 
Model Publication No. 63-29423. In this prior art, an adjusting system for 
adjusting the braking force of the drag mechanism includes a screw type 
mechanism and a cam type mechanism separately from each other. The first 
control element is attached to the screw type mechanism while the second 
control element is attached to the cam type mechanism. In order to adjust 
the braking force of the drag mechanism, the first control element is 
rotatable to determine the reference braking force while only the second 
control element is pivotable to rapidly vary the braking force when a fish 
bites. 
In adjusting the braking force of the drag mechanism while fishing with the 
spinning reel of this type, the greater the amount of a fishing line fed 
from the spool, the smaller the winding diameter of the fishing line 
defined around the spool becomes, even if the braking force of the drag 
mechanism is constant. As a result, a tensile force of the fishing line 
capable of rotating the spool against the braking force of the drag 
mechanism becomes greater. Thus, when the amount of the fishing line fed 
from the spool becomes greater, it is desirable to decrease the braking 
force of the drag mechanism in order to reduce the possibility of breaking 
the fishing line. 
For the purpose of decreasing the braking force of the drag mechanism with 
a feed-out amount of the fishing line, the second control element may be 
used. However, if the second control member is used for decreasing the 
braking force of the drag mechanism, it may possibly reach a limit when a 
fish bites and the angler tries to further decrease the braking force for 
"fighting" against the fish. This is disadvantageous in handling the reel. 
In order to avoid such a problem, it is desirable to control the first 
control element as frequently as possible to set the reference braking 
force to a proper value. However, it is troublesome to individually 
operate the first and second control elements while fishing and 
concurrently the senses of operating these control elements are different, 
which requires an improvement in such a structure. 
SUMMARY OF THE INVENTION 
A primary object of the present invention is to provide an improved 
spinning reel in which a reference braking force of a drag mechanism can 
be readily determined without producing any different senses when 
operating two control elements, and in which the braking force of the drag 
mechanism can be changed to a proper value when a fish bites. 
In order to achieve the object as noted above, a spinning reel according to 
the present invention with the drag mechanism for adjusting the braking 
force through the first and second control elements is characterized in 
that the first control element defines a connected portion while the 
second control element has a connecting element switchable between a 
position engaged with and a position disengaged from the connected 
portion. 
This structure has the following functions and effects. 
As shown in FIGS. 1 and 2, if it is desired to adjust the braking force of 
the drag mechanism D, e.g. when the amount of the fishing line fed from 
the spool 5 increases, the connecting element 15 is moved to a position 
engaged with the connected portion 13 thereby to interconnect the first 
control element 8 and the second control element 11 through the connecting 
element 15 and the connected portion 13. As a result, the reference 
braking force can be changed through an operation of the second control 
element 11. On the other hand, the connecting element 15 can be moved to a 
position disengaged from the connected portion 13 to enable one to quickly 
vary the braking force of the drag mechanism D only through an operation 
of the second control element 11 in a similar manner to the conventional 
art. 
In sum, the present invention allows the reference braking force of the 
drag mechanism D to vary only through the second control element 11 
without operating the first control element 8. 
Therefore, the present invention can provide an improved spinning reel in 
which the reference braking force of the drag mechanism can be easily 
determined without giving the angular any different senses when operating 
two control elements, and in which the braking force of the drag mechanism 
can be changed to a proper value when a fish bites. 
Other objects, features and advantages will be apparent from the following 
detailed description referring to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
A spinning reel embodying the present invention will be described in detail 
referring to the drawings hereinafter. 
FIG. 3 shows a spinning reel comprising a reel body 2 having a handle 1. 
Forwardly of the reel body 2 are mounted a rotor 4 having a bail 3, and a 
spool 5. Rearwardly of the reel body 2 is mounted a drag mechanism D. 
As shown in FIGS. 1 and 2, the drag mechanism D includes a sleeve 7 fitted 
on a rear end of a spool shaft 6 connected to the spool 5 for torque 
transmission, and a first group of disks D1 and second group of disks D2 
fitted on the sleeve 7. The first group of disks D1 adjusts a pressure of 
a spring 10 through a first pressure element 9 by rotating a cap-like 
first control element 8 screwed to a threaded portion 2A defined in the 
reel body 2 to thereby adjust a braking force of the drag mechanism. The 
second group of disks D2 varies a position of a second pressure element 12 
by oscillating a lever-like second control element 11 screwed to the 
threaded portion 2A thereby to adjust the braking force of the drag 
mechanism. 
The first control element 8 of the drag mechanism D can be screwed to a 
limit of a stroke axially along the spool shaft 6. The second control 
element 11 has a lever portion 11A pivotable about a neutral position N in 
opposite directions approximately by 90.degree.. During normal use, the 
first control element 8 is operable to determine a reference braking force 
while only the second control element 11 is operable to vary the braking 
force when a fish bites. 
Also, with this reel, the reference braking force of the drag mechanism D 
can be varied by the second control element 11 while doing fishing without 
operating the first control element 8. 
More particularly, the first control element 8 includes a sleeve portion 8A 
defining a connected portion 13 having serially arranged projections and 
recesses through peripheries thereof. The lever portion 11A of the second 
control element 11 includes a connecting element 15 switchable between a 
position engaged with the connected portion 13 and a position disengaged 
from the connected portion 13, and a pressing type knob 16 for placing the 
connecting element 15 in the engaged position. In order to determine the 
reference braking force, it is sufficient to oscillate the second control 
element 11 while pressing the knob 16. 
The reel further includes a helical groove shaft 17 defining an endless 
helical groove 17A, and a transmission element 18 fitted on the helical 
groove shaft 17 thereby to form an oscillating mechanism for moving the 
spool shaft 6 in a fore and aft direction. A spring linear element 19 is 
mounted between the first pressure element 9 rotatable in unison with the 
first control element 8 and the reel body 2 for producing click sounds. 
Between the second control element 11 and the reel body 2 is mounted a 
spring plate 20 for producing click sounds and a detent element 21 for 
maintaining the spring plate 20 in a neutral position. 
Other embodiments will be set forth below. 
Referring to FIGS. 4 and 5, the connecting element 15 may be operable in 
various ways apart from the foregoing embodiment. For example, the 
connecting element 15 may be pivotable relative to the second control 
element 11 about a support shaft 22 parallel to an axis of the spool shaft 
6 while a control element 23 may be provided to contact and thus oscillate 
the connecting element 15. 
According to the present invention, the connected portion and the 
connecting element may be frictionally engaged with each other, which may 
be applied to various fishing reels, e.g. a fishing reel including a drag 
mechanism having a single group of disks.
