Abstract
An apparatus, having: a staple (404); and a hasp assembly (200) including: a chamber (412) including a home position (430) and a release passage (414); and a release element (328) disposed in the release passage. Forward rotation of the hasp assembly from an upright orientation (208) about a first horizontal axis (220) allows the kinetic element to move under the influence of gravity from the home position into the release passage and into contact with the release element, thereby releasing the staple.
Claims17
An apparatus, comprising:
- a staple;
- a hasp configured to receive the staple;
- a housing that defines a chamber comprising a home position and a release passage,
- wherein the housing also encloses the hasp;
- a kinetic element disposed in the chamber;
- and
- an actuator that comprises a release element that disengages the hasp after forward rotation of the apparatus from an upright orientation allows the kinetic element to slide under an influence of gravity from the home position along the release passage and into contact with the release element, thereby releasing the staple;
- and
- wherein the kinetic element comprises a cylindrical shape comprising a leading face and a trailing face so that the leading face of the kinetic element leads while the kinetic element slides toward the release element until the leading face contacts the release element.

An apparatus, comprising:
- a staple;
- and
- a hasp assembly comprising:
- a hasp configured to engage the staple;
- a chamber comprising a release passage and a home position at an end thereof;
- a kinetic element disposed in the chamber;
- and a release element disposed in the release passage and operatively associated with the hasp;
- wherein when the hasp assembly is in an upright orientation gravity urges the kinetic element into the home position;
- wherein the home position and the release passage are configured such that the kinetic element is held under an influence of gravity in the home position until the hasp assembly experiences a forward rotation of at least a threshold amount, at which orientation the kinetic element moves into the release passage;
- and
- wherein the kinetic element comprises a cylindrical shape comprising a leading face and a trailing face so that the leading face of the kinetic element leads while the kinetic element slides toward the release element until the leading face contacts the release element, and wherein the contact disengages the hasp and thereby releases the staple.
