Apparatus for mounting a cathode ray tube

Abstract

This invention relates to an apparatus for shock mounting in a frame a cathode ray tube of the type having a rear neck portion containing an electron gun integrally formed with a frustum which terminates in a planar or spherical surface on which information is displayed. Compared to the frustum portion, a relatively narrow first annular member constructed of a substantially rigid material is positioned along the cathode ray tube near the convergence of the frustum portion with the neck. This first ring is affixed solidly to the cathode ray tube and has an outer surface which is formed by two surfaces which form an angle with the cathode ray tube's major axis. As such, a surface is provided for opposing a force directed substantially parallel to major axis. A second annular member, also constructed of a substantially rigid material, is positioned circumjacent to the first member, has an inner surface substantially complementary to the outer surface of the first member, and has its outer surface connected to the frame. A third annular member consisting of a resilient material is interposed between the first and second annular members.
