Abstract:

An improved ocular mounting assembly having a pair of ocular support arms which can be extended by sliding out of a box-section assembly housing for supporting a pair of ocular devices attached to the ends of the support arms. The improvement is a pair of stabilizers disposed inside the assembly housing and providing stability against rotational motion when the arms are extended. In one embodiment, the stabilizers are interference-fitted balls, retained in position by retainer holes in the assembly housing, and receding into recess cut-outs at the end of the support arms when the arms are fully retracted. In an alternate embodiment, the stabilizers are L-shaped, and can be either an integral part of the housing or bonded to it with adhesive.
