  • Adjustable keyboard support
    Patent number: 6929228
    Abstract: An adjustable keyboard support mechanism includes a mounting bracket for attachment to a support surface, a platform for supporting a keyboard thereon, a support arm operably connected to the mounting bracket and the platform, and a locking mechanism for restricting height adjustment of the platform with respect to the support surface. The locking mechanism includes a center arm pivotable with respect to the platform and slidable with respect to the mounting bracket, a plurality of frictional members sandwiching and frictionally engaging the center arm, thereby restricting the sliding movement of the center arm with respect to the mounting bracket, and a wedge assembly actuable by pivoting movement of the platform and engageable with the frictional members to both restrict and allow height adjustment of the platform relative to the support surface.
