Abstract
Abstract A plurality of rigid members are utilized for connecting a yoke combination to a platform which is disposed on a television picture tube. The connecting members are shaped such that substantially constant physical contact is maintained between the connecting member, the yoke combination and the platform while the yoke position is adjusted. The yoke combination can be fixed into the optimum position in a permanent nonadjustable fashion through the use of ultrasonic welding or through the use of a small amount of adhesive material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A yoke mount assembly for a television picture tube of the type having a magnetic deflection yoke in operational relationship with the tube, a platform positioned on the external surface of the tube, and a yoke combination which includes a housing which encloses at least a portion of the yoke, wherein the improvement comprises: a plurality of rigid members disposed between and connecting said yoke combination and said platform, said connecting members permitting adjustment of the position of said yoke combination with respect to said platform, said adjustment including rotational translation of said yoke combination with respect to said platform, each of said connecting members having a pair of end portions shaped such that substantially constant physical contact is maintained between one of said end portions of said connecting member and said yoke combination and the other of said end portions and said platform while said yoke position is adjusted.
Claim 2
Dependent Claim
150 words
A yoke mount assembly for a television picture tube of the type having a magnetic deflection yoke in operational relationship with the tube, a platform positioned on the external surface of the tube, and a yoke combination which includes a housing which encloses at least a portion of the yoke, wherein the improvement comprises: a plurality of rigid members disposed between and connecting said yoke combination and said platform, said connecting members permitting adjustment of the position of said yoke combination with respect to said platform, said adjustment including rotational translation of said yoke combination with respect to said platform, each of said connecting members having a pair of end portions shaped such that substantially constant physical contact is maintained between one of said end portions of said connecting member and said yoke combination and the other of said end portions and said platform while said yoke position is adjusted.
Claim 3
Dependent Claim
63 words
A yoke mount assembly in accordance with claim 1 in which said end portions of each one of said connecting members are substantially spherically shaped and said yoke combination and said platform each include a plurality of recesses for closely receiving said end portions of said connecting members with substantially constant physical contact being maintained between said end portions and said receiving recesses.
Claim 4
Dependent Claim
32 words
A yoke mount assembly in accordance with claim 2 in which the end portions of said connecting members in said platform recesses are capable only of pivotal motion in said platform recesses.
Claim 5
Dependent Claim
34 words
A yoke mount assembly in accordance with claim 2 in which at least one of said end portions of each of said connecting members contacts its receiving recess in a plurality of contact points.
Claim 6
Dependent Claim
33 words
A yoke mount assembly in accordance with claim 2 in which at least one of said end portions of each of said connecting members contacts its receiving recess in a plurality of ridges.
Claim 7
Dependent Claim
52 words
A yoke mount assembly in accordance with claim 2 in which said platform recesses receive said end portions of said connecting members in locking fashion such that when said yoke combination is connected to said platform substantially no translation of said yoke combination-platform-tube adjustment is possible until predetermined release forces are provided.
Claim 8
Dependent Claim
43 words
A yoke mount assembly in accordance with claim 6 in which said platform recesses include a locking region of slightly smaller size than said end portion such that a force is required to snap said end portion into and out of said recess.
Claim 9
Dependent Claim
32 words
A yoke mount assembly in accordance with claim 7 in which said end portions of said connection members in said platform recesses are capable only of pivotal motion in said platform recesses.
Claim 10
Dependent Claim
45 words
A yoke mount assembly in accordance with claim 2 in which said end portions of said connecting members and said receiving recesses are provided with an interference fit such that said end portions can be welded into said recesses whereby stresses are relieved upon welding.
Claim 11
Dependent Claim
34 words
A yoke mount assembly in accordance with claim 2 in which at least one of said end portions of each of said connecting members is bonded to its receiving recess with an adhesive material.
