Publication number: 20070029451Abstract: The separator element can be coupled releasably with a mesh cable duct and is suitable for dividing the cable-housing space along at least a portion of the duct into a pair of adjacent longitudinal compartments. The separator element is formed by a wire which is bent in a manner such as to be coupled with a mesh of the base of the mesh cable duct and to have a portion which projects into the cable-housing space.Type: ApplicationFiled: August 4, 2006Publication date: February 8, 2007Applicant: LEGRAND S.P.A.Inventors: Gian Spagnoli, Alan Finco

Patent number: 7055786Abstract: A device for fixing a mesh cable tray to a profiled support section having a plurality of apertures formed in a surface for supporting the tray includes an element having a substantially semi-cylindrical engagement portion which can enclose a portion of a wire of the tray and can restrain it against the support surface. A tail plate is provided which can cooperate with the section on the side opposite to the support surface. The tail plate is connected to the support section by a screw connector.Type: GrantFiled: February 5, 2003Date of Patent: June 6, 2006Assignee: Legrand S.p.AInventors: Luca Garassino, Alan Finco

Patent number: 6855884Abstract: A mesh cable tray comprises a series of longitudinal wires and a series of transverse wires connected to one another at nodes to form a grid, in which each transverse wire includes a base portion from which two parallel arms extend transversely relative to the base portion so that each transverse wire is generally U-shaped. The series of longitudinal wires comprises a pair of longitudinal edge wires which are disposed beside free ends of the parallel arms of the U-shaped transverse wires. The tray has protection members arranged in the regions of the nodes at which the longitudinal edge wires and the parallel arms of the U-shaped transverse wires intersect, in order to cover the free ends of the parallel arms.Type: GrantFiled: October 4, 2002Date of Patent: February 15, 2005Assignee: Legrand S.p.A.Inventors: Gian Piero Spagnoli, Alan Finco

Publication number: 20030156892Abstract: A connecting clamp for connecting a pair of end transverse wires of two consecutive mesh cable tray sections comprises a first element and a second element intended to be mounted inside and outside the mesh tray, respectively, so as to clamp the base parts of the two end transverse wires. The first element comprises a first portion which is coupled with the second element to clamp the base parts of the end transverse wires of the two tray sections and a second portion which is perpendicular to the first portion and forms a pair of seats for restraining the vertical parts of the end transverse wires.Type: ApplicationFiled: February 14, 2003Publication date: August 21, 2003Applicant: LEGRAND S.P.A.Inventors: Alan Finco, Luca Garassino

Publication number: 20030116682Abstract: The joining member is provided for connecting a first mesh cable tray element to a second, longitudinally adjacent mesh cable tray element and includes: a first plate portion with first apertures formed therein for fixing the first plate portion to vertical arms of transverse wires and/or to side longitudinal wires of the two mesh tray elements; and a second plate portion, substantially perpendicular to the first portion, having second apertures formed therein for fixing the said second plate portion to bottom portions of the transverse wires and/or to bottom longitudinal wires of the two mesh tray elements. In a variant of the invention, the joining member enables a first mesh tray element to be connected to a second, longitudinally adjacent channel-like cable duct element.Type: ApplicationFiled: November 22, 2002Publication date: June 26, 2003Applicant: LEGRAND S.P.A.Inventors: Alan Finco, Luca Garassino

Publication number: 20030108385Abstract: The joining clamp comprises separate first and second elements, with at least one of these forming seats for receiving a pair of facing end transverse wires of two adjacent sections of mesh cable tray. The clamp also comprises articulation means for articulated connection of the first and second elements in a pre-assembled condition in which these elements are rotatable relative to each other between an open position, in which the pair of facing end transverse wires can be inserted into the respective seats, and a closed position, in which the facing end transverse wires are securely locked in the seats. The clamp further comprises snap-engagement members for securing the first and second elements together upon relative rotation thereof from the open position to the closed position.Type: ApplicationFiled: December 10, 2002Publication date: June 12, 2003Applicant: LEGRAND S.P.A.Inventors: Alan Finco, Luca Garassino
