  • Patent number: 7949312
    Abstract: A bi-axial swivel assembly allows the rotation of a bracket around the longitudinal axis of a support shaft when the restriction cam lies inside an imaginary reference plane. The attitude of the bracket is allowed to change around the longitudinal axis of the support shaft. Only if the bracket allows the restriction cam get off a recess, the perpendicular surface serves to prevent the restriction cam from protruding outside the imaginary reference plane. The attitude of the bracket can be prevented from changing around the rotation axis perpendicular to the longitudinal axis. The bi-axial swivel assembly allows the wire to penetrate through first and second hollow spaces. When the bracket rotates around the longitudinal axis, the wire is only forced to suffer from a slight torsion within the first hollow space. The wire can be protected from a larger flexure.

  • Patent number: 7813115
    Abstract: A second enclosure defines the backside superposed on a first enclosure for relative rotation around a rotation axis set perpendicular to the front surface of the first enclosure in an electronic apparatus. First, second and third flat surfaces are defined on the backside of the second enclosure at positions inside the contour of the second enclosure. The receiving pieces receive the first flat surface when the second enclosure is set in the reference attitude. When the second enclosure is set in the lateral attitude by rotation by plus or minus 90 degrees, the second flat surface or the third flat surface is received on the receiving pieces behind the second enclosure. Even if friction resulting from the contact roughens the first, second and third surfaces, the asperity and scratches on the surfaces are hidden behind the second enclosure.
