Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
An apparatus for mounting a cathode ray tube, having a rear neck portion integrally formed with a frustum, in a frame, comprising: a. a first annular member constructed of a substantially rigid material, positioned along said cathode ray tube near the convergence of said frustum portion and said neck of said cathode ray tube, affixed solidly to said cathode ray tube and having an outer surface which contains two surfaces which form an angle with the major axis of said cathode ray tube such that a surface for opposing a force substantially parallel to said major axis is provided; b. a second annular member constructed of a substantially rigid material positioned circumjacent to said first annular member having an inner surface substantially complementary to said outer surface of said first annular member and whose outer surface is affixed to said frame; and c. a resilient material interposed between said first annular member and said second annular member.
Claim 2
Independent Claim
157 words
An apparatus for mounting a cathode ray tube, having a rear neck portion integrally formed with a frustum, in a frame, comprising: a. a first annular member constructed of a substantially rigid material, positioned along said cathode ray tube near the convergence of said frustum portion and said neck of said cathode ray tube, affixed solidly to said cathode ray tube and having an outer surface which contains two surfaces which form an angle with the major axis of said cathode ray tube such that a surface for opposing a force substantially parallel to said major axis is provided; b. a second annular member constructed of a substantially rigid material positioned circumjacent to said first annular member having an inner surface substantially complementary to said outer surface of said first annular member and whose outer surface is affixed to said frame; and c. a resilient material interposed between said first annular member and said second annular member.
Claim 3
Dependent Claim
32 words
An apparatus as in claim 1 wherein the first annular member is positioned along said frustum portion of said cathode ray tube just forward of said neck of said cathode ray tube.
Claim 4
Dependent Claim
21 words
An apparatus as in claim 1 wherein the first annular member is affixed to the cathode ray tube with an adhesive.
Claim 5
Dependent Claim
17 words
An apparatus as in claim 1 wherein the frustum portion of the cathode ray tube is conical.
Claim 6
Dependent Claim
32 words
An apparatus as in claim 1 wherein the outer surface of the first annular member comprises a V-shape groove defining surfaces substantially orthogonal to said major axis of said cathode ray tube.
Claim 7
Dependent Claim
17 words
An apparatus as in claim 5 wherein the outer surface of the first annular member is concave.
Claim 8
Independent Claim
169 words
An apparatus for mounting a cathode ray tube in a frame, said tube having a rear neck portion integrally formed with a frustum having a face at the front thereof substantially orthogonal to the tube's major axis, comprising: a. a first annular member constructed from a resilient material, positioned at the periphery of said face of said cathode ray tube and contacting said frame; b. a second annular member constructed of a substantially rigid material, affixed to said frustum portion of said cathode ray tube immediately forward of said neck portion and having an outer surface which contains two surfaces which form an angle with said cathode ray tube's major axis; c. a third annular member constructed of a substantially rigid material positioned circumjacent to said second annular member having an inner surface substantially complementary to said outer surface of said second annular member and whose outer surface is connected to said frame; and d. a resilient material interposed between said second annular member and said third annular member.
Claim 9
Independent Claim
169 words
An apparatus for mounting a cathode ray tube in a frame, said tube having a rear neck portion integrally formed with a frustum having a face at the front thereof substantially orthogonal to the tube's major axis, comprising: a. a first annular member constructed from a resilient material, positioned at the periphery of said face of said cathode ray tube and contacting said frame; b. a second annular member constructed of a substantially rigid material, affixed to said frustum portion of said cathode ray tube immediately forward of said neck portion and having an outer surface which contains two surfaces which form an angle with said cathode ray tube's major axis; c. a third annular member constructed of a substantially rigid material positioned circumjacent to said second annular member having an inner surface substantially complementary to said outer surface of said second annular member and whose outer surface is connected to said frame; and d. a resilient material interposed between said second annular member and said third annular member.
Claim 10
Dependent Claim
59 words
An apparatus as in claim 7 wherein the first annular member includes a concave inner surface allowing said first annular member to receive said cathode ray tube by contacting said cathode ray tube around the periphery of the base of said frustum such that said cathode ray tube is substantially supported along five of the six possible force directions.
