Patent number: 5988615Abstract: A device for fixing an object to the edge of a flat support, the support having a top face on which the object is to be fixed and a lower face. A vertical section piece, positionable close to the edge of the support, is perpendicular to the plane of the support. The upper end of the section piece has an element which engages and holds the object on the top face of the support, e.g. rods projecting into a cavity in the object. An arm extending perpendicular to the section piece supports at one end thereof a cam for being selectively moved to press against and released from pressing against the lower face of the support. The section piece passes through an opening in the arm and the arm with the cam thereon is tiltable with reference to the section piece for locking the arm along the section piece. A lever then rotates the cam to press against the lower face of the support.Type: GrantFiled: March 9, 1998Date of Patent: November 23, 1999Assignee: Virax S.A.Inventor: Patrice Churoux
