Patent number: 11981536Abstract: An elevator car has one or more sidewalls (4a, 4b) defining an interior space (2) for accommodating passengers; a roof (3) including a support frame (8) and a working platform (12) which is suspendably connected to the support frame (8). The working platform moves between a stowed position, above the interior space, and an operational position, within the interior space. The elevator car also includes a blocking member (20, 21), located at the support frame (8), and arranged to move between an unblocking position and a blocking position. When the blocking member (20, 21) is in the blocking position, the blocking member is configured to prevent the working platform (12) from being moved into the stowed position.Type: GrantFiled: November 3, 2022Date of Patent: May 14, 2024Assignee: OTIS ELEVATOR COMPANYInventors: Fabrice Boniface, Morgane Appourchaux, Aurelien Fauconnet, Franck Rivoiret

Patent number: 11866298Abstract: An elevator counterweight assembly (11) includes a counterweight structure (38), at least one safety brake (12a, 12b) mounted on the counterweight structure (38), and a safety actuation mechanism (16) including a connection (17) for a suspension member (18). The safety actuation mechanism (16) is configured to move, relative to the counterweight structure (38), between a normal position, and a safety position. In the safety position the safety actuation mechanism (16) is arranged to actuate the at least one safety brake (12a, 12b) and thereby brake the counterweight structure (38). The counterweight assembly (11) also includes a mechanical actuator (22), configured, when actuated, to apply a force to the safety actuation mechanism (16) and thereby move the safety actuation mechanism (16) from the normal position to the safety position, e.g. for the purposes of a handover test.Type: GrantFiled: December 23, 2020Date of Patent: January 9, 2024Assignee: OTIS ELEVATOR COMPANYInventors: Aurelien Fauconnet, Franck Rivoiret

Patent number: 11261056Abstract: Counterweights for elevator systems are described. The counterweights include a frame and a counterweight safety system attached to the frame. The safety system includes a safety brake mounted to an upright of the frame and configured to enable engagement with a guide rail to apply a braking force. A sheave is mounted to the frame and configured to operably connect to tension members. The sheave is configured to move between a first position when under tension and a second position when the tension is lost. A connecting link operably connects the sheave to the safety brake. The connecting link has first and second link members operably connected between the sheave and the safety brake.Type: GrantFiled: December 16, 2019Date of Patent: March 1, 2022Assignee: OTIS ELEVATOR COMPANYInventors: Aurelien Fauconnet, Franck Rivoiret, Frederic Beauchaud

Patent number: 8387310Abstract: A sliding door carriage for a vehicle includes a first point for fixing a first cable strand for driving in a first direction, and a second point for fixing a second cable strand for driving in a second direction. Each fixing point is offset toward a rear of the sliding door carriage relative to a direction of driving by the respective cable strand. The sliding door carriage can be included in a sliding door driving system, and the sliding door driving system can be included in a vehicle. The bulk of the sliding door driving system in a body of a vehicle can be reduced.Type: GrantFiled: March 18, 2009Date of Patent: March 5, 2013Assignee: Inteva Products France SASInventors: Jean-Louis Robalo, Michel Mounie, Francois-Paul Meurou, Franck Rivoiret

Patent number: 7726455Abstract: A clutch comprises an input pinion and an output pinion associated with a rotatable locking member that has a surface inclined with respect to an axis of rotation of the locking member. The surface cooperates with an engagement member, and the locking member is movable between a first position and a second position. In the first position, the surface forms a recess to receive the engagement member, and in the second position, the surface forms a projection to force the engagement member into abutment with the input pinion to establish a driveable connection between the input pinion and the output pinion.Type: GrantFiled: April 27, 2007Date of Patent: June 1, 2010Assignee: ArvinMeritor Light Vehicle Systems —FranceInventors: Dominique Benoit, Franck Rivoiret, Thierry Pebre
