Abstract
Abstract A control lever for a transmission of a vehicle comprising a frame of the vehicle, a pair of rods pivotally connected to the control lever, which rods are arranged at right angles with each other, a housing fixedly secured to the frame, a spherical bearing for mounting the control lever on the housing, the spherical bearing comprising an outer race mounted in the housing, and a spherical bushing mounted on the control lever within the outer race so as to allow a sliding contact of the spherical bushing with the outer race, a cover fixedly secured to the control lever, which cover has a pair of guide slots formed therein positioned diametrically opposite sides to each other relative to the control lever, and a pair of guide pins fixedly secured to the housing, which guide pins are aligned with other in a direction parallel to one of the rods and adapted to be inserted within the guide slots.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
A control lever for a transmission of a vehicle, comprising: a frame of the vehicle; a housing fixedly secured to said frame; spherical bearing means for mounting said control lever on said housing, said spherical bearing means comprising an outer race mounted on said housing, and a spherical bushing mounted on said control lever within said outer race so as to allow a sliding contact of said spherical bushing with said outer race; a pair of rod means pivotally connected to said control lever means, said rod means being arranged at right angles with each other; a cover fixedly secured to said control lever, said cover having a pair of guide slots formed therein positioned diametrically opposite sides to each other relative to said control lever; and a pair of guide pins fixedly secured to said housing, said guide pins being aligned with each other in a direction parallel to one of said rod means and adapted to be inserted within said respective guide slots.
Claim 2
Dependent Claim
165 words
A control lever for a transmission of a vehicle, comprising: a frame of the vehicle; a housing fixedly secured to said frame; spherical bearing means for mounting said control lever on said housing, said spherical bearing means comprising an outer race mounted on said housing, and a spherical bushing mounted on said control lever within said outer race so as to allow a sliding contact of said spherical bushing with said outer race; a pair of rod means pivotally connected to said control lever means, said rod means being arranged at right angles with each other; a cover fixedly secured to said control lever, said cover having a pair of guide slots formed therein positioned diametrically opposite sides to each other relative to said control lever; and a pair of guide pins fixedly secured to said housing, said guide pins being aligned with each other in a direction parallel to one of said rod means and adapted to be inserted within said respective guide slots.
Claim 3
Dependent Claim
32 words
A control lever for a transmission of a vehicle as set forth in claim 1 wherein the center axis of said guide pins passes through the revolution center of said spherical bushing.
Claim 4
Dependent Claim
157 words
A control lever for a transmission of a vehicle, comprising: a frame of the vehicle; a pair of rod means pivotally connected to said control lever means, said rod means being arranged at right angles with each other; a housing fixedly secured to said frame; spherical bearing means for mounting said control lever on said housing, said spherical bearing means comprising an outer race mounted on said housing, said outer race having formed therein a pair of diametrically opposed holes which are aligned with each other in a direction parallel to one of said rod means, and a spherical bushing mounted on said control lever within said outer race so as to allow a sliding contact of said spherical bushing with said outer race, said spherical bushing having formed therein a pair of diametrically opposed slots; and a pair of guide pins each adapted to be inserted into said respective holes and engage with said respective slots.
Claim 5
Dependent Claim
157 words
