Patent number: 11958549Abstract: A standard component of a vehicle equippable with a plurality of wheels or a plurality of track systems for engaging the ground, such as an axle housing or a frame of the vehicle, comprises a connector dedicated to connecting a given one of the track systems to the vehicle and provided during original manufacturing of the standard component of the vehicle. This may facilitate installation of the track systems on the vehicle.Type: GrantFiled: July 16, 2018Date of Patent: April 16, 2024Assignee: Camso Inc.Inventors: Alain Lussier, Frederic Couture, Etienne Poulin

Patent number: 11958550Abstract: A track system for traction of a vehicle (e.g., a compact track loader or other construction vehicle) which may be designed to improve ride quality (e.g., reduce vibrations) for an operator and/or enhance other aspects of its performance or that of the vehicle. For example, a track of the track system may be frictionally driven and without transversal rigid parts (e.g., metallic cores). Also, power generation and transmission functions may be implemented by the track system. For instance, a motor and a transmission may be at least mostly contained within the track system.Type: GrantFiled: August 16, 2018Date of Patent: April 16, 2024Assignee: Camso Inc.Inventors: Alain Lussier, Frederic Couture, Etienne Poulin

Publication number: 20220105998Abstract: A track system for a vehicle on a ground, wherein the track system may be designed to enhance ride quality (e.g., comfort), stability, load distribution on the ground, manoeuvrability (e.g., steerability), adaptability to ground and/or working conditions, and/or other aspects of the track system and/or the vehicle, such as by being movable relative to a frame of the vehicle (e.g., horizontally, vertically, and/or pivotally), resiliently supporting wheels of the track system (e.g., with elastomeric bushings or other components), and/or varying how much of the track engages the ground (e.g., reducing that to facilitate turning).Type: ApplicationFiled: October 6, 2021Publication date: April 7, 2022Inventors: Etienne Poulin, Alain Lussier, Frederic Couture, David Gingras

Patent number: 11002165Abstract: A muffler has a housing enclosing a plurality of chambers. A first flow path extends from an inlet to an outlet passing through a bypass chamber. A flow tube has a plurality of perforations being open to a chamber other than the bypass chamber. A second in flow path passes from the inlet to the outlet without passing through the bypass chamber and passing through the perforations. Exhaust gas is introduced into the muffler via the inlet and discharged therefrom via the outlet. A first portion of the exhaust gas flows from the inlet to the outlet along the first flow path. A second portion of the exhaust gas flows from the inlet to the outlet along the second flow path, the first and second portions mixing at least in the outlet chamber. A semi-closed tube has an open end being open to one of the chambers and a closed end.Type: GrantFiled: July 21, 2017Date of Patent: May 11, 2021Assignee: BOMBARDIER RECREATIONAL PRODUCTS INC.Inventor: Etienne Poulin

Patent number: 7614103Abstract: The present invention provides a stretcher having a brake mechanism that can be selectively activated to influence the movement of the stretcher supported by an inclined surface. The brake mechanism of the stretcher progressively increases the amount of friction between the stretcher and the surface of which the stretcher is supported to reduce or stop movements of the stretcher. The stretcher further includes a pulling member influencing the position or the activation of the brake mechanism on the stretcher and high friction means associated with the bottom side of the stretcher. The present invention also provides a size reduction mechanism requesting limited storage space for the stretcher when not in use and a foot restraint to secure the feet of the patient on the stretcher and offer additional volume to carry additional material with the patient. A method for braking a stretcher on an inclined plane is also disclosed.Type: GrantFiled: December 6, 2007Date of Patent: November 10, 2009Assignee: Societe de Commercialisation des Produits de la Recherche Appliquee - Socpra Sciences et Genie S.E.C.Inventors: Benoit Beaudry, Hugo Bastien, Francois Bergeron, Jean-Sébastien Gosselin, Etienne Poulin, Vincent Deschamps-Sonsino, Noemie Seguin-Tremblay
