Abstract

A dual-bearing reel spool brake device configured to brake a spool being rotatably mounted to a reel unit by centrifugal force is provided. The dual-bearing reel spool break device includes a rotary member, a brake shoe, and a brake drum. The rotary member is configured to be rotated in conjunction with at least rotation of the spool in a fishing-line releasing direction. The brake shoe is elastically engaged with the rotary member, wherein the brake shoe is pivotable and detachable with the rotary member. The brake drum is disposed radially inwards or radially outwards of the brake shoe, wherein the brake drum has a peripheral surface contactable with the brake shoe.

Claims (45)

1. A dual-bearing reel spool brake device configured to brake a spool being rotatably mounted to a reel unit by centrifugal force, the dual-bearing reel spool brake device comprising:

a rotary member being configured to be rotated in conjunction with at least rotation of the spool in a fishing-line releasing direction;

a brake shoe being elastically engaged with the rotary member, the brake shoe being pivotable and detachable with the rotary member; and

a brake drum being disposed radially inwards or radially outwards of the brake shoe, the brake drum having a peripheral surface contactable with the brake shoe,

the rotary member having a pivot shaft coupled to the brake shoe, and

the brake shoe being elastically and pivotally engaged with the pivot shaft.

2. The dual-bearing reel spool brake device according to claim 1 , further comprising

a moving mechanism being configured to relatively move and position the brake shoe and the brake drum in an axial direction of a rotary shaft of the spool,

wherein the peripheral surface is a tapered surface contactable with the first end of the brake shoe at different diameters.

3. The dual-bearing reel spool brake device according to claim 2 , wherein

the pivot shaft is disposed along an axial direction being skew to the rotary shaft.

4. The dual-bearing reel spool brake device according to claim 2 , wherein

the pivot shaft is disposed along an axial direction in parallel to the rotary shaft.

5. The dual-bearing reel spool brake device according to claim 1 , wherein

the brake shoe is made of synthetic resin having elasticity,

the brake shoe has a support hole in which the pivot shaft is fitted, and a slit opened from an inner peripheral surface to an outer peripheral surface of the support hole at a width less than a width of the pivot shaft.

6. The dual-bearing reel spool brake device according to claim 5 , wherein

the pivot shaft is fitted in the support hole by clearance fit.

7. The dual-bearing reel spool brake device according to claim 5 , wherein

the pivot shaft has a restricting protrusion extending radially outwards,

the restricting protrusion is fitted into the slit for restricting a pivot range of the brake shoe.

8. The dual-bearing reel spool brake device according to claim 1 , further comprising

a second brake shoe being elastically engaged with the rotary member, wherein

the rotary member has a second pivot shaft being coupled to the second brake shoe,

the second brake shoe is pivotable and detachable with the rotary member

the first and second pivot shafts are disposed at predetermined intervals in a circumferential direction of the rotary member.

9. The dual-baring reel spool brake device according to claim 8 , wherein

the second brake shoe has mass different from mass of the first brake shoe.

10. The dual-bearing reel spool brake device according to claim 8 , further comprising

a switch mechanism configured to make at least one of the first and second brake shoes to make contact with the brake drum.

11. A dual-bearing reel, comprising:

the dual-baring reel spool brake device according to claim 1 .

12. A dual-bearing reel spool brake device configured to brake a spool being rotatably mounted to a reel unit by centrifugal force, the dual-bearing reel spool brake device comprising:

a rotary member being configured to be rotated in conjunction with at least rotation of the spool in a fishing-line releasing direction;

a brake shoe being elastically engaged with the rotary member, the brake shoe being pivotable and detachable with the rotary member, the brake shoe having a first end and a second end being disposed on an opposite side of the first end, and the brake shoe being pivotably coupled to the rotary member at a position between the first end and a center of gravity; and

a brake drum disposed radially inwards or radially outwards of the brake shoe, the brake drum having a peripheral surface contactable with the brake shoe,

being disposed radially inwards of the brake shoe, and

the peripheral surface being an outer peripheral surface contactable with the first end of the brake shoe.

13. A dual-bearing reel spool brake device configured to brake a spool being rotatably mounted to a reel unit by centrifugal force, the dual-bearing reel spool brake device comprising:

a rotary member being configured to be rotated in conjunction with at least rotation of the spool in a fishing-line releasing direction;

a brake shoe elastically engaged with the rotary member, being pivotable and detachable with the rotary member having a pivot shaft being coupled to the rotary member, and being elastically and rotatably engaged with the rotary member; and

a brake drum being disposed radially inwards or radially outwards of the brake shoe, the brake drum having a peripheral surface contactable with the brake shoe.

14. The dual-bearing reel spool brake device according to claim 13 , wherein

the rotary member is made of synthetic resin having elasticity,

the rotary member has a support hole in which the pivot shaft is fitted, and a slit opened from an inner peripheral surface to an outer peripheral surface of the support hole at a width less than a width of the pivot shaft.
