    • A variable friction hinge is mounted between a cover and a base of an electronic device and has a pintle, a stationary leaf and a washer assembly. The pintle is connected to the cover. The stationary leaf is connected to the base and has an activating panel with an activating edge. The washer assembly has a movable washer, an abrasion washer and a biasing member. The movable washer selectively abuts the activating edge of the activating panel and has an elongated hole slidably mounted securely around the pintle. The movable and the abrasion washers have teeth corresponding to and selectively engaging each other, causing less friction when engaged and more friction when disengaged. When rotated the movable washer selectively disengages the teeth causing the hinge to have greater friction when being rotated one way than the other.
    • 可变摩擦铰链安装在电子设备的盖和基座之间,并具有枢轴,固定叶片和垫圈组件。 枢轴连接到盖子。 固定叶片连接到基座,并具有带激活边缘的激活面板。 垫圈组件具有可移动的垫圈,磨损垫圈和偏置构件。 可移动的垫圈选择性地邻接激活面板的激活边缘并且具有可靠地安装在枢轴周围的细长孔。 可移动和磨擦垫圈具有对应于并且选择性地彼此接合的齿,当接合时产生较小的摩擦并且在分离时产生更大的摩擦。 当旋转时,可动垫圈选择性地脱离齿,导致铰链在相对于另一个旋转时具有更大的摩擦力。

    • A door hinge arrangement for a door is provided including a hinge bearing and a hinge pin adapted to be received in the hinge bearing and being rotatable in the hinge bearing about a vertical axis of the hinge pin. The hinge pin has a protruding cam portion extending perpendicular to the axis and the hinge bearing has a recess formed in a side wall to receive a length of the cam portion when the hinge pin is in a first angular orientation relative to the hinge bearing corresponding to a closed position. When the hinge pin is rotated relative to the hinge bearing to a second angular orientation, the cam acts against the recess to translate the axis of the pin from a first axial position to a second axial position, such that the hinge pin will first be translated laterally as the hinge pin is rotated, and then the hinge pin will be rotated about the second axial position.
    • 提供了一种用于门的门铰链装置,其包括铰链轴承和铰链销,铰链销适于被容纳在铰链轴承中并且可围绕铰链销的垂直轴线在铰链轴承中旋转。 铰链销具有垂直于轴线延伸的突出凸轮部分,并且铰链轴承具有形成在侧壁中的凹部,以在铰链销相对于对应于铰链轴承的铰链轴承处于第一角度取向时接纳一定长度的凸轮部分 关闭位置 当铰链销相对于铰链轴承旋转到第二角度定向时,凸轮作用在凹部上,以将销的轴线从第一轴向位置平移到第二轴向位置,使得铰链销将首先被翻转 当铰链销旋转时,铰链销将围绕第二轴向位置旋转。
