Patent number: 8042234Abstract: Disclosed is a clamping device including a collar having at least one pair of projecting lugs and tightening means co-operating with said lugs. Each lug of a pair is equipped with reinforcement means suitable for opposing deformation of said lugs under the action of the tightening means. Each lug has a connection portion via which it is connected to a belt portion of the collar, which connection portion is upstanding relative to said belt portion, and a tightening wall, with which the tightening means come into engagement and which is folded back towards the belt portion. A space is formed between the connection portion and the tightening wall.Type: GrantFiled: April 12, 2006Date of Patent: October 25, 2011Assignee: Etablissements CaillauInventors: Nicolas Rigollet, Fabrice Prevot, Tony Rointru

Publication number: 20100287740Abstract: The system comprises a clamping collar (10) suitable for being brought resiliently from its rest configuration in which its diameter is small to an expanded configuration. The system further comprises a support ring (20) suitable for being encircled by the collar, and an expander (40) suitable for co-operating with the ring firstly to hold the ring in an expanded configuration in which the collar (10) encircling the ring is also in its expanded configuration when the expander and the ring are in a first relative position, and secondly to enable the ring to contract and the clamping system to tighten under the resilient return force exerted by the collar encircling the ring when the expander and the ring are in a second relative position.Type: ApplicationFiled: July 11, 2008Publication date: November 18, 2010Applicant: Etablissements CaillauInventors: Nicolas Rigollet, Fabrice Prevot, Tony Rointru

Patent number: 7802821Abstract: A device includes a clamping collar having a belt that has two substantially cylindrical faces and that is suitable for being tightened around an article to be clamped; and at least one positioning including a securing plate that is disposed facing a first face of the belt while being retained relative to the belt; and a positioning portion that is suitable for positioning the device relative to the article to be clamped. When the collar is in its initial, non-tightened state, the securing plate is braced against the first face of the belt, wherein at the beginning of tightening, the plate deforming causes the bracing effect to cease, thereby allowing the belt and the plate to move relative to each other. The plate is suitable for being deformed while the collar is being tightened onto the article so as to present curvature that matches the curvature of the belt.Type: GrantFiled: July 16, 2008Date of Patent: September 28, 2010Assignee: Etablissements CaillauInventors: Nicolas Rigollet, Fabrice Prevot, Eric Mesnard
