Abstract

Abstract A dragging device for a spinning reel applies a rotational resistance to a spool shaft which carries a spool for winding up a fishing line. The dragging device includes a first drag mechanism provided with first dragging members connected to the reel body, second dragging members connected to the spool shaft and rotatable together with the spool shaft, and an adjusting member for bringing these dragging members into press-contact with each other to adjust the dragging force applied to the spool shaft. The dragging device also includes a second drag mechanism provided with a rotary member rotatable with respect to the spool shaft, third dragging members connected to the rotary member, fourth dragging members connected to the spool shaft and rotatable in association with the spool shaft, and a press-contact member to bring all of the dragging members into press-contact with each other. The dragging device also includes a locking mechanism for locking the rotary member to the reel body, thereby preventing the line from being snapped due to a sudden pull by a fish.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 227 words
A dragging device for a spinning reel including a reel body, a spool shaft slidable longitudinally relative to the reel body and a spool mounted on the spool shaft, said dragging device applying a rotational resistance force against rotation of said spool shaft and comprising a first drag mechanism and a second drag mechanism each for applying a rotational resistance force against rotation of said spool shaft; said first drag mechanism comprising first dragging members connected to said reel body, second dragging members connected to said spool shaft, said second dragging members being rotatable together with said spool shaft, and an adjusting means for bringing said first and second dragging members in press-contact with each other to adjust an amount of said rotational resistance force applied against rotation of said spool shaft; said second drag mechanism comprising a rotary member rotatable with respect to said spool shaft, third dragging members connected to said rotary member, fourth dragging members connected to said spool shaft, said fourth drag members being rotatable with said spool shaft, and a press-contact means for bringing said third and fourth dragging members into press-contact with each other, said dragging device further comprising a locking mechanism interposed between said rotary member and said reel body to lock said rotary member to said reel body to prevent said rotary member from rotating with said spool shaft.
Claim 2
Dependent Claim 227 words
A dragging device for a spinning reel including a reel body, a spool shaft slidable longitudinally relative to the reel body and a spool mounted on the spool shaft, said dragging device applying a rotational resistance force against rotation of said spool shaft and comprising a first drag mechanism and a second drag mechanism each for applying a rotational resistance force against rotation of said spool shaft; said first drag mechanism comprising first dragging members connected to said reel body, second dragging members connected to said spool shaft, said second dragging members being rotatable together with said spool shaft, and an adjusting means for bringing said first and second dragging members in press-contact with each other to adjust an amount of said rotational resistance force applied against rotation of said spool shaft; said second drag mechanism comprising a rotary member rotatable with respect to said spool shaft, third dragging members connected to said rotary member, fourth dragging members connected to said spool shaft, said fourth drag members being rotatable with said spool shaft, and a press-contact means for bringing said third and fourth dragging members into press-contact with each other, said dragging device further comprising a locking mechanism interposed between said rotary member and said reel body to lock said rotary member to said reel body to prevent said rotary member from rotating with said spool shaft.
Claim 3
Dependent Claim 92 words
A dragging device for a spinning reel as set forth in claim 1, wherein said spool shaft includes a rotary tubular shaft which is non-rotatable relative to said spool shaft and movable axially thereof, said rotary tubular shaft supporting said first, second, third and fourth dragging members, said press-contact member being interposed between said first drag mechanism and said second drag mechanism, said adjusting member cooperating with said press-contact member to adjust a rotational resistance force applied by each of said first and second drag mechanisms against rotation of said spool shaft.
Claim 4
Dependent Claim 68 words
A dragging device for a spinning reel as set forth in claim 1, wherein said rotary member comprises a cylinder having a bottom portion and said third and fourth dragging members are housed in a bore in said cylinder, said press-contact member causing said third and fourth dragging members to make press-contact with said bottom portion of said cylinder, said press-contact member being fixed to said rotary member.
Claim 5
Dependent Claim 62 words
A dragging device for a spinning reel as set forth in claim 3, wherein said press-contact member is fixed to said rotary member by a screw means and a position of said press-contact member relative to said rotary member is adjustable to thereby enable adjustment of a rotational resistance force applied by said second drag mechanism against rotation of said spool shaft.
Claim 6
Dependent Claim 91 words
A dragging device for a spinning reel as set forth in claim 1, wherein said rotary member includes a round outer periphery, said locking mechanism comprises a retaining portion formed on the round outer periphery of said rotary member and, a locking member supported to said reel body and operable to advance or retract with respect to said retaining portion, said locking member having an operating member for causing said locking member to advance or retract with respect to said retaining portion to lock said rotary member to said reel body.
Claim 7
Dependent Claim 59 words
A dragging device for a spinning reel as set forth in claim 1, wherein said first drag mechanism is disposed at a rear portion of said reel body and said second drag mechanism is disposed in front of said first drag mechanism, said locking member at said locking mechanism being disposed at a lateral side of said reel body.
Claim 8
Dependent Claim 60 words
A dragging device for a spinning reel as set forth in claim 6, wherein a support cylinder projects from a rear portion of said reel body, and said adjusting member comprises a cylinder having on an outer periphery thereof an operating unit adapted to enable hand-adjustment of said adjustment member, said adjusting member being screwably connected with said support cylinder.
Claim 9
Dependent Claim 24 words
A dragging device for a spinning reel as set forth in claim 7, wherein said operating member for said locking member comprises a lever.
