  • Patent number: 7146684
    Abstract: Retention element, especially a lid stay or a flap holder, comprising a first arm, having a first friction face, a second arm, connected pivotably around an articulation axis to the first arm, an operating element and a locking element, forming a locking face, wherein the locking unit is arranged to the second arm, a braking element, having a braking face, to which the locking face is held in frictional contact, and having a second friction face, which is held at least indirectly in abutment to the first friction face, wherein the operating element, in a first rotational direction of the arms relative to each other, urges the locking face against the braking face, wherein in the first rotational direction of the two arms relative to each other the maximal braking torque between the locking face and the braking face is larger than the maximal frictional torque between the first friction face and the second friction face, wherein in a second rotational direction of the two arms relative to each other the maxima

  • Publication number: 20050005398
    Abstract: A hinge for connecting a first folding element (30) to a second folding element (30) of a folding flap or folding door. The hinge includes a fixing element (1, 101, 201) having a first fixing face (7, 107, 207) by means of which it can be contactingly fixed to the first folding element (30); a first arm (2, 102, 202) connected to the fixing element (1, 101, 201) so as to be pivotable around a first pivot axis (3, 103, 203) between a first position and a second position; a second arm (4, 104, 204) having a fixing device (27, 127, 227) by which the second arm (4, 104, 204) can be fixed to the second folding element (31), and is connected to the first arm (2, 102, 202) so as to be pivotable around a second pivot axis (5, 105, 205) extending parallel to the first pivot axis (3, 103, 203) between a first position and a second position.

  • Patent number: 6463627
    Abstract: A lid stay for holding a lid of a piece of furniture has a first arm (1) and a second arm (2) pivotably connected to the first arm (1). The arms (1, 2) are movable between an open position and a closed position around a swivel axis (4). A friction mechanism (9, 10) is active between the first arm (1) and the second arm (2). A spring mechanism acts upon the second arm (2) in the direction towards the open position or in the direction towards the closed position. The spring mechanism influences the frictional force that acts upon the friction means (9, 10).

  • Patent number: 5823411
    Abstract: A locking device for motor vehicle roof trunks has a bottom part and a lid. On two sides of the trunk (1), which extend parallel relative to one another, the lid (3) is pivotable by two hinges around a hinge axis relative to the bottom part (2). The hinges each include a first hinge part (14) associated with the lid (3) and a second hinge part (15) associated with the bottom part (2). All hinges have a common actuating rod (23) which includes hinge pins (30) movable parallel to the direction of the hinge axis (12). Each hinge pin (30) is movably guided in a bearing housing (21) associated with the bottom part (2) and may engage a sleeve (17) associated with the first hinge part (14). A cylinder lock (34) enables all hinges associated with one side to be actuated centrally by actuating the actuating rod 23 towards the closed or open position.

  • Patent number: 5546705
    Abstract: A support for holding a closed element, such as a flap or lid in a closed or open position relative to a container has a first and second arm. One of the arms is connected to the container by a first pivot bearing and the other arm is connected to the closing element by a second pivot bearing. The two arms are connected to one another by a third pivot bearing and by a pressure spring operational between the arms. The two arms are supported relative to one another in a first arm position, which corresponds to the closed position, where the pivot bearings are close to one another, or in a second position, which corresponds to the open position, where the pivot bearings are positioned remote from one another.
