Abstract: An improved plunger for a self-locking pin having a plunger section and a base section in a unitary one-piece construction, wherein the plunger section is at least substantially orthogonal to the base section. Wherein the base section comprises at least a substantially planar configuration, and may provide for biasing of the plunger section. A portion of the plunger extends outwardly from a bore of the self locking pin in which the plunger resides. The plunger section is preferably wedge-shaped, or may possess other geometrical shapes, while the portion of the plunger disposed inside the bore is of a cylindrical shape. An extended biasing section tor positioning of the plunger section may be in unitary construction with the base section.

Abstract: A self-locking pin having a shaft, a headed end, and plunger biased in a bore in the pin. The portion of the detent or plunger that extends outwardly from the bore may be wedge-shaped, or possess other geometrical shapes, while the portion of the plunger disposed inside the bore is of a cylindrical shape or other geometrical shapes. The plunger comprises a plunger section and a biasing section in a unitary one-piece construction. At least one transition ledge is defined on the plunger. The shaft is staked at points along the perimeter of the bore so that the inwardly extending surface created by the staking abuts the transition ledge and prevents the plunger from rotating or being removed from the bore.

Abstract: A pull pin is configured to lock in a forward position to prevent accidental or undesirable retraction of the pull pin. The pull pin has a housing, a pull pin shaft, an inner shaft, a first and second spring, and at least one ball bearing. The housing has a ball locking space, which holds the ball bearing between the locking space and a ball aperture formed in the pull pin shaft to thereby lock the pull pin shaft in the forward position. Only upon the application of an external force to the inner shaft, which aligns a ball release portion with the ball aperture, can the ball bearing move into the ball release portion and thereby move out of said locking space, allowing for the retraction of the pull pin shaft.

Abstract: A self-locking pin having a shaft, a headed end, and detent means biased in a bore in the pin. The portion of the detent or plunger that extends outwardly from the bore is wedge-shaped, while the portion of the plunger disposed inside the bore is cylindrical. A transitional angle is formed at the point where the configuration of the plunger changes from cylindrical to wedge-shaped. The transitional angle defines shoulders on either side of the plunger. The shaft is staked at points along the perimeter of the bore so that the inwardly extending surface created by the staking abuts the shoulders and prevents the plunger from rotating or being removed from the bore. In an alternate embodiment, the plunger may be rotated to a locked depressed position.
