QUICK-RELEASE FASTENER

摘要

The invention relates to a quick-release fastener (100) of the ball-pin type, consisting of a tubular body (102) provided with a radial opening (108), an enlarged head (104), a rod (112) that can move axially within the body and through the head, a ball (110) capable of moving radially between a released position in which it rests in a reduced cross-section (132) of the rod (112) inside the body and a locked position in which it protrudes radially beyond the body through the radial opening (108), and a lever (114) that pivots about a pin (118), which lever includes at least one cam surface (142) that is in contact with the head. The rotational actuation of the lever draws the rod toward the head and causes the ball to move into the released position.

主权项

1. Quick-release fastener (100) consisting of a tubular body (102) having an axis of revolution (A), a portion of which includes at least one radial opening (108); an enlarged head (104); and a rod (112) that can move axially within the body and through the head, which rod includes at least one portion having a reduced cross-section (132); at least one ball (110) capable of moving radially between a released position in which it rests in the reduced cross-section (132) of the rod (112) inside the body and a locked position in which it protrudes radially beyond the body through the radial opening (108); and a lever (114) that pivots about a pin (118) that is an integral part of the rod and of the lever, which lever includes at least one cam surface (142) that is in contact with the head; which fastener is configured such that the rotation of the lever causes the rod to be drawn toward the head, thereby causing the ball to move into the released position.
