Specifically, the pin includes a base that is mountable to the pole vault standard or upright stanchion, and a support arm. The support arm is spring-biased and disposable between an operative, extended position and a collapsed, pivoted position. When in the extended position, the support arm or pin assembly is structured to support a cross bar thereon, such as a cross bar used in a pole vaulting track and field event. Upon sufficient impact, the support arm will collapse or pivot in a downward direction, thereby releasing the cross bar and minimizing potential injury to an athlete, either by avoiding a violent impact with the cross bar or the pin assembly, itself. ## Claims ### Claim 1 A pole vault cross bar pin, said pin being mountable to a pole vault standard and configured to at least temporarily support a portion of a cross bar, said pin comprising: a base, said base being mountable to the pole vault standard, a support arm, said support arm being disposable between an extended position and a collapsed position, said extended position being defined as said support arm being extended laterally outward from a facing surface of the standard when said pin is mounted to the standard, and said collapsed position being defined as said support arm being disposed in an at least partially downwardly pivoted direction when said pin is mounted to the standard, a pivoting assembly structured to maintain said support arm in said extended position at least until a downward force is exerted upon said support arm sufficient to allow said support arm to pivot downward into said collapsed position via said pivoting assembly, and said pivoting assembly comprising a biasing device disposed in an engaging relation with a biased device, wherein said biased device is biased at least partially into an engaging relation with a detent when said support arm is disposed in said extended position, and wherein said biased device is released from said detent when said support arm is disposed into said collapsed position. ### Claim 2 (depends on 1) The pin as recited in claim 1 wherein said base comprises a joint upon which said support arm pivots, said joint being disposed proximate to the facing surface of the standard when said pin is mounted to the standard. ### Claim 3 (depends on 2) The pin as recited in claim 2 wherein said joint is disposed a distance less than 0.5 inches from the facing surface of the standard when said pin is mounted to the standard. ### Claim 4 (depends on 1) The pin as recited in claim 1 wherein said detent is disposed on an end of said base and structured to at least partially engage said biased device when said support arm is disposed in said extended position. ### Claim 5 (depends on 4) The pin as recited in claim 4 wherein said biased device comprises a ball disposed in an at least partially engaged relation with said detent when said support arm is disposed in said extended position. ### Claim 6 (depends on 5) The pin as recited in claim 5 wherein said ball and said detent contact one another at two separate contact points when said support arm is disposed in said extended position. ### Claim 7 (depends on 6) The pin as recited in claim 6 wherein said detent comprises a curvature with a radius smaller than a radius of said ball. ### Claim 8 (depends on 7) The pin as recited in claim 7 wherein said ball and said detent only contact at said two separate contact points when said support arm is disposed in said extended position. ### Claim 9 (depends on 5) The pin as recited in claim 5 wherein said biasing device comprises a spring disposed within an internal channel of said support arm, said spring comprising a proximal end and a distal end, said proximal end of said spring being disposed in a biasing engaged relation with said ball. ### Claim 10 (depends on 9) The pin as recited in claim 9 further comprising a bias adjustment device disposed at said distal end of said spring, said bias adjustment device being configured to allow selective adjustment of said spring. ### Claim 11 (depends on 10) The pin as recited in claim 10 wherein said bias adjustment device comprises a screw selectively adjustable in an engaged relation against said distal end of said spring. ### Claim 12 A pole vault cross bar pin, said pin being mountable to a pole vault standard and configured to at least temporarily support a portion of a cross bar, said pin comprising: a base, said base being mountable to the pole vault standard, a support arm, said support arm being pivotally disposable between an extended position and a collapsed position via a pivoting assembly, said extended position being defined as said support arm being disposed in an axially aligned relation with said base, and said collapsed position being defined as said support arm being disposed in an at least partially downwardly angled relation relative to said base, said pivoting assembly comprising a biasing spring disposed within an internal channel of said support arm, a biased ball disposed at a proximal end of said spring, and a detent disposed on an end of said base, said biased ball being at least partially engaged with said detent via said spring when said support arm is disposed in said extended position, and said pivoting assembly being structured to maintain said support arm in said extended position at least until a downward force is exerted upon said support arm sufficient to dislodge said biased ball from said detent and pivot said support arm downward into said collapsed position. ### Claim 13 (depends on 1) The pin as recited in claim 1 wherein said base comprises a pivoting joint upon which said support arm pivots between said extended position and said collapsed position, said joint being disposed proximate a facing surface of the standard when said pin is mounted to the standard. ### Claim 14 (depends on 13) The pin as recited in claim 13 wherein said pivoting joint is disposed a distance less than 0.5 inches from the facing surface of the standard when said pin is mounted to the standard. ### Claim 15 (depends on 14) The pin as recited in claim 14 wherein said biased ball and said detent contact one another at two separate contact points when said support arm is disposed in said extended position. ### Claim 16 (depends on 15) The pin as recited in claim 15 wherein said detent comprises a curvature with a radius smaller than a radius of said biased ball. ### Claim 17 (depends on 16) The pin as recited in claim 16 wherein said biased ball and said detent only contact at said two separate contact points when said support arm is disposed in said extended position. ### Claim 18 (depends on 16) The pin as recited in claim 16 further comprising a bias adjustment device disposed at said distal end of said biasing spring, said bias adjustment device being configured to allow selective adjustment of said biasing spring. ### Claim 19 (depends on 18) The pin as recited in claim 18 wherein said bias adjustment device comprises a screw selectively adjustable in an engaged relation against said distal end of said biasing spring.
