Abstract

Abstract Automatic transmission control in which the manual control level is supported by a mounting assembly for limited turning movement in a longitudinal direction about an axis beneath the vehicle floor adjacent to the transmission to effect a change in transmission operation. The mounting assembly includes a lever carrier that is drivingly connected to a rotatable mounting shaft extending through the sides of a protective support bracket suspending from a floor-mounted baseplate. The lever is also pivotally mounted on the carrier for limited lateral movement to permit disengagement of the lever from positive stops corresponding to different transmission operations. A torquetransmitting lever connected directly to the control-leveroperated mounting shaft is drivingly connected by a linkage to the transmission.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 233 words
A transmission control for a transmission comprising an supporting plate mounted on the floor of a vehicle, a support bracket depending from said supporting plate adjacent to said transmission, a torque-transmitting pivot shaft mounted for limited rotation with respect to a first axis in said support bracket and having opposed ends extending outside of said bracket, connector means for operatively connecting one end of the pivot shaft to said transMission, fastener means mounted on the other end of said pivot shaft for retaining said pivot shaft on said support bracket, a control lever carrier secured to said pivot shaft for rotation therewith, a control lever, pivot means for pivotally mounting said control lever to said carrier so that said control lever can turn said pivot shaft with respect to said first axis and to mount said lever for turning movement in a transverse direction with respect to said first axis, a detent plate having a series of spaced stops thereon, spring means supported on said carrier and contacting said control lever for urging said control lever laterally against said stops, and slot means in said carrier permitting said control lever to be moved laterally away from any one of said stops and subsequently to be moved longitudinally to effect limited rotation of said carrier and said connected control shaft to thereby actuate said connecting means and condition said transmission for a predetermined operation.
Claim 2
Dependent Claim 233 words
A transmission control for a transmission comprising an supporting plate mounted on the floor of a vehicle, a support bracket depending from said supporting plate adjacent to said transmission, a torque-transmitting pivot shaft mounted for limited rotation with respect to a first axis in said support bracket and having opposed ends extending outside of said bracket, connector means for operatively connecting one end of the pivot shaft to said transMission, fastener means mounted on the other end of said pivot shaft for retaining said pivot shaft on said support bracket, a control lever carrier secured to said pivot shaft for rotation therewith, a control lever, pivot means for pivotally mounting said control lever to said carrier so that said control lever can turn said pivot shaft with respect to said first axis and to mount said lever for turning movement in a transverse direction with respect to said first axis, a detent plate having a series of spaced stops thereon, spring means supported on said carrier and contacting said control lever for urging said control lever laterally against said stops, and slot means in said carrier permitting said control lever to be moved laterally away from any one of said stops and subsequently to be moved longitudinally to effect limited rotation of said carrier and said connected control shaft to thereby actuate said connecting means and condition said transmission for a predetermined operation.
Claim 3
Dependent Claim 70 words
The transmission shift control defined in claim 1 and further including a housing having an opening therein through which said transmission control lever extends, fastener means connecting said housing to said baseplate, a detent plate cover carried by said carrier and surrounding said transmission control lever for movement therewith, said detent plate cover being supported by said carrier immediately below said opening in said housing to thereby block said opening.
Claim 4
Dependent Claim 160 words
A transmission shift control mounted on the floor of a vehicle comprising a manually operable control member movable to any one of a plurality of different positions for conditioning a transmission for different predetermined operations, a support for said control member having a side and spaced first and second extensions, one of said extensions having a laterally extending slot therein through which said control member extends, pivot means mounting said control member to the other of said extensions for turning movement, a baseplate secured to the floor of a vehicle, a support bracket having side and end walls suspended from said baseplate and disposed adjacent to said transmission, a shaft mounted for turning movement in said support bracket adjacent to said transmission, connecting means interiorly of said support bracket for drivingly connecting said support for said control member to said shaft, and linkage means disposed exteriorly of said support bracket for drivingly connecting said transmission control member to a transmission.
Claim 5
Dependent Claim 160 words
A transmission shift control mounted on the floor of a vehicle comprising a manually operable control member movable to any one of a plurality of different positions for conditioning a transmission for different predetermined operations, a support for said control member having a side and spaced first and second extensions, one of said extensions having a laterally extending slot therein through which said control member extends, pivot means mounting said control member to the other of said extensions for turning movement, a baseplate secured to the floor of a vehicle, a support bracket having side and end walls suspended from said baseplate and disposed adjacent to said transmission, a shaft mounted for turning movement in said support bracket adjacent to said transmission, connecting means interiorly of said support bracket for drivingly connecting said support for said control member to said shaft, and linkage means disposed exteriorly of said support bracket for drivingly connecting said transmission control member to a transmission.
Claim 6

A control for a power transmission in a vehicle comprising a manually operated lever member movable to a plurality of different positions for conditioning the transmission for different predetermined operations, a carrier for said lever member, support means mounting said carrier and said lever member for limited movement together about a first axis, pivot means pivotally supporting said lever member on said carrier for limiting turning movement about a second axis; said support means comprising a torque transmitting pivot shaft secured to said carrier for rotatably supporting said carrier and said lever member and for transmitting a control force to the transmission, a baseplate secured in the vehicle, and a supporting bracket suspended from said baseplate having an opening therethrough, said pivot shaft having a portion extending through said opening; retainer means for retaining said pivot shaft in said bracket, and torque transmitting means operatively connecting said pivot shaft to the transmission to enable said lever member to condition the transmission for predetermined operations in response to movement of said lever member to predetermined positions.
Claim 7
Dependent Claim 175 words
A control for a power transmission in a vehicle comprising a manually operated lever member movable to a plurality of different positions for conditioning the transmission for different predetermined operations, a carrier for said lever member, support means mounting said carrier and said lever member for limited movement together about a first axis, pivot means pivotally supporting said lever member on said carrier for limiting turning movement about a second axis; said support means comprising a torque transmitting pivot shaft secured to said carrier for rotatably supporting said carrier and said lever member and for transmitting a control force to the transmission, a baseplate secured in the vehicle, and a supporting bracket suspended from said baseplate having an opening therethrough, said pivot shaft having a portion extending through said opening; retainer means for retaining said pivot shaft in said bracket, and torque transmitting means operatively connecting said pivot shaft to the transmission to enable said lever member to condition the transmission for predetermined operations in response to movement of said lever member to predetermined positions.
