Abstract

A clamp assembly for a vehicle shift mechanism includes a steering column having a stationary portion and a moveable portion. The clamp assembly also includes a shifter operatively coupled to the moveable portion of the steering column and slidably engaged with the stationary portion of the steering column. The clamp assembly further includes a primary rake lever configured to translationally adjust the moveable portion of the steering column. The clamp assembly yet further includes a secondary rake lever operatively coupled to the primary rake lever and operative to exert a clamping force on a portion of the shifter during translational adjustment of the moveable portion.

First claim

Having thus described the invention, what is claimed is:

1. A clamp assembly for a vehicle shift mechanism comprising:
a steering column having a stationary portion and a moveable portion;
a shifter operatively coupled to the moveable portion of the steering column and slidably engaged with the stationary portion of the steering column;
a primary rake lever configured to translationally adjust the moveable portion of the steering column;
a secondary rake lever operatively coupled to the primary rake lever and operative to exert a clamping force on a portion of the shifter during translational adjustment of the moveable portion; and
a rake bolt operatively coupled to the primary rake lever and to the stationary portion of the steering column, the secondary rake lever operatively coupled to the rake bolt, the rake bolt and the secondary rake lever each rotatable upon rotation of the primary rake lever, the secondary rake lever rotatable between a locked position and an unlocked position;
further comprising a glide system comprising:
a sliding member extending from the shifter; and
a bracket extending from the stationary portion, the bracket having an inner wall defining a slot extending longitudinally along the stationary portion, the sliding member slidably disposed within the slot; the sliding member comprising a T-shaped geometry.

2. The clamp assembly of claim 1 , wherein the rake bolt comprises a first end and a second end, the rake bolt operatively coupled to the primary rake lever proximate the first end and operatively coupled to the secondary rake lever proximate the second end.

3. The clamp assembly of claim 1 , wherein the rake bolt is operatively coupled to the stationary portion proximate the first end and the second end.

4. The clamp assembly of claim 1 , wherein the locked position exerts the clamping force on the shifter to maintain the position of the shifter relative to the stationary portion of the steering column.

5. The clamp assembly of claim 1 , wherein a bolt is disposed between the secondary rake lever and the shifter to exert the clamping force on the portion of the shifter.

6. A clamp assembly for a vehicle shift mechanism comprising:
a steering column having a stationary portion and a moveable portion;
a shifter operatively coupled to the moveable portion of the steering column and slidably engaged with the stationary portion of the steering column;
a primary rake lever configured to translationally adjust the moveable portion of the steering column;
a secondary rake lever operatively coupled to the primary rake lever and operative to exert a clamping force on a portion of the shifter during translational adjustment of the moveable portion; and
a rake bolt operatively coupled to the primary rake lever and to the stationary portion of the steering column, the secondary rake lever operatively coupled to the rake bolt, the rake bolt and the secondary rake lever each rotatable upon rotation of the primary rake lever, the secondary rake lever rotatable between a locked position and an unlocked position, the sliding member clamped between the secondary rake lever and the inner wall of the bracket when the secondary rake lever is in the locked position.

7. A clamp assembly for a vehicle shift mechanism comprising:
a steering column having a stationary portion and a moveable portion;
a shifter operatively coupled to the moveable portion of the steering column and slidably engaged with the stationary portion of the steering column;
a primary rake lever configured to translationally adjust the moveable portion of the steering column;
a secondary rake lever operatively coupled to the primary rake lever;
a cam portion of the secondary rake lever configured to bias a bolt against a portion of the shifter in a locked position, the bolt being spring biased to retract away from contact with the portion of the shifter in an unlocked position; and
a rake bolt operatively coupled to the primary rake lever and to the stationary portion of the steering column, the secondary rake lever operatively coupled to the rake bolt.

8. The clamp assembly of claim 7 , wherein the rake bolt comprises a first end and a second end, the rake bolt operatively coupled to the primary rake lever proximate the first end and operatively coupled to the secondary rake lever proximate the second end.

9. The clamp assembly of claim 7 , wherein the rake bolt is operatively coupled to the stationary portion proximate the first end and the second end.

10. The clamp assembly of claim 7 , wherein the rake bolt and the secondary rake lever are each rotatable upon rotation of the primary rake lever, the secondary rake lever rotatable between the locked position and the unlocked position.

11. The clamp assembly of claim 7 , further comprising a bolt spring surrounding a portion of the bolt, the bolt spring biasing the bolt into the unlocked position.

12. The clamp assembly of claim 7 , further comprising a plunger operatively coupled to an engagement end of the bolt, the plunger pre-loaded toward the shifter.

13. The clamp assembly of claim 10 , further comprising a glide system comprising:
a sliding member extending from the shifter; and
a bracket extending from the stationary portion, the bracket having an inner wall defining a slot extending longitudinally along the stationary portion, the sliding member slidably disposed within the slot.

14. The clamp assembly of claim 13 , wherein the sliding member comprises a T-shaped geometry.

15. The clamp assembly of claim 13 , wherein the sliding member is clamped between the bolt and the inner wall of the bracket when assembly is in the locked position.
