Patent number: 11137019Abstract: A joint assembly between a first component and a second component comprises a ball portion configured to be connected to the first component. A socket is configured to be connected to the second component or ground and comprises a socket base, a socket cover, and a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint. At least one biasing member is in the joint assembly. A clamp clamps the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.Type: GrantFiled: October 31, 2016Date of Patent: October 5, 2021Assignee: D-BOX TECHNOLOGIES INC.Inventors: Robert Rousseau, Benoit Lupien, Steve Boulais, Jean-Francois Menard

Patent number: 10746269Abstract: A linear actuator comprises a motor for producing a bi-directional rotational output. A casing is connected to the motor at a proximal end, the casing having an inner cavity defining a joint surface. A threaded shaft is within the inner cavity of the casing and actuated by the motor for rotation. A sliding tube assembly has a sliding tube in sliding arrangement with the inner cavity of the casing for moving in translation in an axial direction relative to the casing. A pair of traveling nuts is connected to the sliding tube assembly for moving with the sliding tube in the axial direction, the traveling nuts being operatively engaged to the threaded shaft for converting a rotational motion of the threaded shaft into a translation of the sliding tube, the traveling nuts being on opposite sides of a member of the sliding tube assembly connecting the traveling nuts to the sliding tube.Type: GrantFiled: October 30, 2015Date of Patent: August 18, 2020Assignee: D-BOX TECHNOLOGIES INC.Inventors: Robert Rousseau, Steve Boulais, Benoit Lupien, Jean-Francois Menard

Patent number: 8657376Abstract: The present document describes a link member for providing an interface between an actuator and a seat base. The link member has a translational degree of freedom and at least two rotational degrees of freedom. The link member comprises: a joint member having a spherical surface, the joint member for attachment to one of the actuator and the seat base; a housing for attachment to the other one of the actuator and the seat base; and a slider mounted on the spherical surface and within the housing. The slider is free to move in a direction of a translational plane within the housing thereby providing the translational degree of freedom. Furthermore, the slider is free to slide on the spherical surface and to pivot about a first axis and a second axis thereby providing the at least two rotational degrees of freedom.Type: GrantFiled: March 23, 2011Date of Patent: February 25, 2014Assignee: D-Box Technologies Inc.Inventors: Stéphane Gagnon, Jean-François Ménard, Steve Boulais, Sylvain Trottier
