Abstract
Abstract One end of a spring loaded bail wire 13 is secured to a pivotally mounted lever arm 3 having an arcuate cam projection 4 of tapering radius provided with a recess 18. The cam projection is surrounded by a circular extension 7' on one end of a spring biased slider 7 mounted in a support block 2 integral with the reel rotor 1 A follower projection 17 on the inner surface of the circular extension engages the cam projection, and is configured to mate with the recess to latch the bail in its cocked position. Upon rotation of the rotor the projecting slider strikes a fixed slider kick member 14, and is cammed inwardly thereby to unseat the projection from the recess and release the cocked bail. The two spring forces increasingly offset each other during the bail return, to thereby inplement a smooth and quiet tripping operation with a very low slider impact against the fixed kick member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
258 words
An automatic bail latching and releasing mechanism for an outer skirted spinning reel, comprising: a reel body (19), a slider kick (14) mounted on the reel body, a rotor (1) rotatably mounted to the reel body, a pair of supporting blocks (2,2') provided at diametrically opposite positions outside of the rotor, a pair of bail arm levers (3, 12) pivotally secured to the respective supporting blocks, a bail wire (13) having its respective ends mounted on the bail arm levers, spring means (5) mounted proximate one of the bail arm levers for biasing the bail arm toward a released position, a slider (7) mounted in the supporting block mounting the other bail arm lever for linear movement with respect thereto, an annular opening in one end of the slider having a projection (17) thereon, a spring member (8) for biasing the slider outwardly from said supporting block, a raised, generally arcuate cam surface (4) on the other bail arm lever disposed within the annular opening in engagement with the slider projection, the cam surface having a gradually increasing radius and a recess (18) adapted to mate with the slider projection to latch the bail wire and slider at a cocked position, the cocked slider projecting out from its supporting block and striking the slider kick as the rotor is turned to release the cocked bail wire, whereby the return of the bail wire to its released position compresses the spring member to thereby oppose the return force of the spring means and reduce the bail wire return impact.
Claim 2
Dependent Claim
258 words
An automatic bail latching and releasing mechanism for an outer skirted spinning reel, comprising: a reel body (19), a slider kick (14) mounted on the reel body, a rotor (1) rotatably mounted to the reel body, a pair of supporting blocks (2,2') provided at diametrically opposite positions outside of the rotor, a pair of bail arm levers (3, 12) pivotally secured to the respective supporting blocks, a bail wire (13) having its respective ends mounted on the bail arm levers, spring means (5) mounted proximate one of the bail arm levers for biasing the bail arm toward a released position, a slider (7) mounted in the supporting block mounting the other bail arm lever for linear movement with respect thereto, an annular opening in one end of the slider having a projection (17) thereon, a spring member (8) for biasing the slider outwardly from said supporting block, a raised, generally arcuate cam surface (4) on the other bail arm lever disposed within the annular opening in engagement with the slider projection, the cam surface having a gradually increasing radius and a recess (18) adapted to mate with the slider projection to latch the bail wire and slider at a cocked position, the cocked slider projecting out from its supporting block and striking the slider kick as the rotor is turned to release the cocked bail wire, whereby the return of the bail wire to its released position compresses the spring member to thereby oppose the return force of the spring means and reduce the bail wire return impact.
Claim 3
Dependent Claim
52 words
A mechanism as claimed in claim 1, wherein the slider comprises an elongated slot in the other end thereof, a protruding member on the other supporting block engages the slot in the slider, and the spring member is disposed between one end of the slot and one end of the protruding member.
Claim 4
Dependent Claim
62 words
A mechanism as claimed in claim 1, wherein the length of the cam surface is at least as long as the stroke of the bail wire from its cocked to its released position, and the recess is at the position where the radius of the cam surface is a minimum, so as to be most easily engaged and disengaged with the projection.
Claim 5
Dependent Claim
62 words
A mechanism as claimed in claim 2, wherein the length of the cam surface is at least as long as the stroke of the bail wire from its cocked to its released position, and the recess is at the position where the radius of the cam surface is a minimum, so as to be most easily engaged and disengaged with the projection.
Claim 6
Dependent Claim
27 words
A mechanism as claimed in claim 1, wherein the depth of the projection and recess is just sufficient to latch the bail wire in its cocked position.
Claim 7
Dependent Claim
17 words
A mechanism as claimed in claim 5, wherein the projection and the recess are semicircular in shape.
Claim 8
Dependent Claim
19 words
A mechanism as claimed in claim 1, wherein the outer rear end of the slider has an inclined surface.
Claim 9
Dependent Claim
18 words
A mechanism as claimed in claim 1, wherein the surface of the slider kick has a ramp shape.
Claim 10
Dependent Claim
25 words
A mechanism as claimed in claim 1, further comprising a counterbalance weight on the other supporting block for preventing the eccentric rotation of the rotor.
