Abstract:
1. A low-force release mechanism comprising: a main structure including a cavity and a shaft; a trap having a hollowed portion and being received by the main structure, the hollowed portion surrounding the shaft; a moveable internal spring pin having an opened cavity and a retaining portion, the internal spring pin being located within the cavity of the main structure; the cavity of the spring pin having an internal spring to facilitate locking of the trap and the internal spring pin in any order; a release pin located within the internal spring pin and extending into the shaft; a lift spring interposed between the release pin and the main structure enabling the release pin to be biased; at least one trigger being positioned in a hole of the main structure and engaging the retaining portion of the internal spring pin to retain the internal spring pin in a locked position; attachments by which a container is attached to the main structure and the trap; and at least one ball bearing or slug located in the hollowed portion of the trap and the shaft, and interacting with the hollowed portion of the trap and the release pin; the release pin being moveable to effect a locked position of the ball bearing or the slug against the trap; whereby removing the trigger from the hole of the main structure unlocks the internal spring pin and the release pin to allow the ball bearing or the slug to retract thus releasing the trap which allows the attachments to be released.
