Anchor

摘要

An anchor comprises first, second and third flanges. A surface of the first flange facing the second flange defines a plane. A contour of the first flange projected onto the plane extending beyond a contour of the second flange projected onto the plane. A base connecting part includes the third flange and the second flange. An accessory connecting part operatively connected to the base connecting part includes the first flange. The third flange is movable relative to at least one of the first and second flanges between a first position and a second position. In the first position, a contour of the third flange projected onto the plane is contained within the contour of the second flange projected onto the plane. In the second position, the contour of the third flange projected onto the plane extends beyond the contour of the second flange projected onto the plane.

主权项

1. An anchor for selectively connecting to a base, the base having at least one hexagonal base aperture, the anchor comprising:
a case having an integrally formed case flange, the case flange having a hexagonal contour congruent with the at least one hexagonal base aperture for inserting the anchor into the base; a latch operatively connected to the case, the latch including a latch body and a latch flange fixed to the latch body, the latch being movable about an axis relative to the case between a locked position and an unlocked position, in the locked position the latch flange being adapted to secure the anchor on the base, in the unlocked position the latch flange being adapted to permit insertion and removal of the anchor from the at least one hexagonal aperture of the base; and a lever connected to the latch for moving the latch between the locked and unlocked positions.
