  • Patent number: 7184262
    Abstract: A latch unit is mounted on an electronic device having first and second housings. The latch unit includes a hook member for interlocking the first and second housings. The hook member is mounted in the first housing and has opposite first and second engaging ends. The first engaging end projects from the first housing and extends into and releasably engages the second housing upon movement of the hook member to an engaging position when the first housing is positioned at a first transverse position. The second engaging end projects from the first housing and extends into and releasably engages the second housing upon movement of the hook member to the engaging position when the first housing is positioned at a second transverse position.

  • Patent number: RE40055
    Abstract: A position unit is mounted on an electronic device and includes a catch member and a locking member. The catch member defines a gap which has a width that is reducible when the catch member moves from a non-catching position to a catching position and that is expandable when the catch member moves from the catching position to the non-catching position. The locking member has an engine end extending into the gap. The locking member is operable to move the catch member from the non-catching position to the catching position and from the catching position to an urging position. The engaging end of the locking member engages the catch member when the width of the gap is reduced upon movement of the catch member to the catching position. The engaging end of the locking member disengages from the catch member when the width of the gap is enlarged upon movement of the catch member to the non-catching position.
