  • Patent number: 8640305
    Abstract: A toggle type hinge (10) has a damper assembly mounted on the flange (12) of its hinge cup. The damper assembly provides a damping resistance to the closing movement of the hinge over its final stage. The damper assembly includes: a sleeve (21) which houses a linear damper. The sleeve (21) is mounted on a groove (26) on the hinge cup flange (12) and is held in position by a holder (15). A wing (22) on the sleeve (21) is arranged to come into engagement with an arm (11) of the hinge, causing the sleeve to rotate about its longitudinal axis (25). A cam arrangement (19, 23) between the hinge cup flange (12) and the sleeve (21) causes the sleeve to move along its axis (25) as it rotates. The axial movement of the sleeve (21) causes compression of the damper.

  • Patent number: 8567011
    Abstract: The present invention relates to an actuator (1), comprising an output member (6); a resilient element (8) connected to said output member (6) so as to urge it in a first direction; and an hydraulic rotation damper (5) with a closed cylinder cavity, a rotational damper shaft which extends into the cylinder cavity, and a piston dividing the cylinder cavity into a first side and a second side. Within the rotation damper (5), the rotational movement of the damper shaft is converted into a translational movement of the piston along a longitudinal axis of the shaft. A restricted fluid passage communicates said first and second sides. The damper shaft is connected over a gearing (10, 15, 17) to the output member (6) and resilient element (8) of the actuator for damping movement of said output member (6) in said first direction.
