Abstract
An accessory mounting interface for a firearm is provided. The accessory mounting interface has a firearm accessory, a first elongated fastener, a second fastener, and an elongated slot in a firearm. The second fastener has two straight edges parallel to each other, and at least one of the two straight edges prevent the second fastener from rotating beyond a closed position once a portion of the second fastener has passed through and at least partially cleared the elongated slot.
Claims20
An accessory mounting interface for a firearm, the interface comprising:
- a firearm accessory having at least one through hole extending from a first surface to a second surface of the firearm accessory;
- a first elongated fastener arranged through the through hole and having a first end extending below the second surface of the firearm accessory;
- a second fastener rotationally mated to the first elongated fastener and having a length greater than a width, the length measured along a longitudinal axis of the second fastener, the second fastener comprising a plurality of straight edges;
- a first slot protrusion, separated into first and second halves surrounding the at least one through hole;
- and
- an elongated slot in a firearm, the elongated slot having a length greater than a width, and wherein the width is between the length and width of the second fastener, such that the second fastener can pass through the elongated slot when the longitudinal axis of the second fastener is arranged parallel to a longitudinal axis of the elongated slot, but abuts a sidewall of the elongated slot when the longitudinal axis of the second fastener is arranged obliquely to the longitudinal axis of the elongated slot, wherein
- at least one of the plurality of straight edges preventing the second fastener from rotating further than a closed position when the at least one of the straight edges abuts the sidewall of the elongated slot.
An accessory mounting interface for a firearm, the interface comprising:
- a firearm accessory having at least one through hole extending from a first surface to a second surface of the firearm accessory;
- a first fastener;
- a second fastener rotationally mated to the first fastener, the second fastener comprising at least one straight edge and first and second curved edges having a first radius and third and fourth curved edges having a second radius greater than the first radius;
- a first slot protrusion having inner arcs surrounding the through hole, the inner arcs having a radius of curvature greater than or equal to the second radius;
- and
- an elongated slot in a firearm, the elongated slot having a length greater than a width, such that the second fastener can pass through the elongated slot when the longitudinal axis of the second fastener is arranged parallel to a longitudinal axis of the elongated slot, but abuts a sidewall of the elongated slot when the longitudinal axis of the second fastener is arranged obliquely to the longitudinal axis of the elongated slot;
- wherein
- at least one of the first fastener and the second fastener is arranged through the through hole;
- the second fastener comprises a closed position and an open position relative to the first fastener, wherein the longitudinal axis of the second fastener is parallel to the longitudinal axis of the elongated slot when the second fastener is in the open position, and the closed position is rotated between 45° and 135° from the open position;
- and
- the at least one straight edge prevents the second fastener from rotating further than the closed position when the second fastener abuts the sidewall of the elongated slot.
