Shift mechanism for a vehicle
A shift mechanism for a vehicle has a lever portion movable between two or more shift states, an engagement mechanism that selectively allows the lever portion to move between the shift states, and a rotatable knob that cooperates with the engagement mechanism such that the engagement mechanism allows the lever portion to move between the shift states when the rotatable knob is rotated in at least a first rotational direction.
1 . A shift mechanism for a vehicle, comprising:
a shifter gate;
a lever portion movable between two or more shift states;
an engagement mechanism that selectively allows the lever portion to move between the two or more shift states, the engagement mechanism including a locking pin that cooperates with the shifter gate to selectively allow the lever portion to move between the two or more shift states; and
a rotatable knob that cooperates with the engagement mechanism such that the engagement mechanism allows the lever portion to move between the shift states when the rotatable knob is rotated in at least a first rotational direction.
2 . The shift mechanism according to claim 1 , wherein:
the lever portion includes a body portion; and
the engagement mechanism further includes a rod assembly that passes through the body portion.
3 . The shift mechanism according to claim 2 , wherein:
the engagement mechanism further includes a ramped element in cooperation with the rod assembly; and wherein
the rotatable knob includes a ramped surface that cooperates with the ramped element such that rotation of the rotatable knob presses the ramped element against the rod assembly to allow the lever portion to move between the two or more shift states.
4 . The shift mechanism according to claim 2 , wherein the locking pin extends from the rod assembly.
5 . The shift mechanism according to claim 4 , wherein the locking pin extends radially away from the rod assembly in opposite radial directions.
6 . The shift mechanism according to claim 5 , wherein the rod assembly further includes:
a guide portion proximate the locking pin; and
a tubular portion extending from the guide portion to a location proximate the ramped element.
7 . (canceled)
8 . The shift mechanism according to claim 3 , further including at least one return spring that biases the ramped surface of the rotatable knob toward a locked position wherein the lever portion is prohibited from moving between the two or more shift states.
9 . The shift mechanism according to claim 3 , further including at least one return spring that biases the rod assembly toward a locked position wherein the lever portion is prohibited from moving between the shift states.
10 . The shift mechanism according to claim 1 , wherein said rotatable knob is rotatably supported on said lever portion.
11 . A vehicle comprising:
a shifter gate;
a lever portion movable between shift states;
an engagement mechanism that selectively allows the lever portion to move between the shift states, the engagement mechanism including a locking pin that cooperates with the shifter gate to selectively allow the lever portion to move between the two or more shift states;
a rotatable knob that cooperates with the engagement mechanism such that the engagement mechanism allows the lever portion to move between the shift states when the rotatable knob is rotated in at least a first rotational direction; and
wherein the rotation of the rotatable knob causes the locking pin to move up and down within the shifter gate.
12 . The vehicle according to claim 11 , wherein:
the lever portion includes a body; and
the engagement mechanism further includes a rod assembly that passes through the body.
13 . The vehicle according to claim 12 , wherein:
the engagement mechanism further comprises a ramped element in cooperation with the rod assembly; and
the rotatable knob includes a ramped surface that cooperates with the ramped element such that rotation of the knob presses the ramped element against the rod assembly to allow the lever portion to move between the shift states.
14 . The vehicle according to claim 13 , wherein the locking pin extends from the rod assembly.
15 . The vehicle according to claim 14 , wherein the locking pin comprises a pin extending radially away from the rod assembly in opposite directions.
16 . The vehicle according to claim 13 , further comprising at least one return spring that biases the ramped surface of the rotatable knob toward a locked position where the lever portion is prohibited from moving between the shift states.
17 . The vehicle according to claim 13 , further comprising at least one return spring that biases the rod assembly toward a locked position where the lever portion is prohibited from moving between the shift states.
18 . A shift mechanism for a vehicle, comprising:
a shifter gate;
a lever portion means for moving between shift states;
an engagement mechanism means for selectively allowing the lever portion means to move between the shift states, the engagement means including a locking pin that cooperates with the shifter gate to selectively allow the lever portion to move between the two or more shift states;
a rotatable knob means for cooperating with the engagement mechanism to allow the lever portion to move between the shift states; and
wherein the rotation of the rotatable knob causes the locking pin to move within the shifter gate.
19 . The shift mechanism according to claim 18 , further comprising:
a rod assembly means;
a ramped surface means on the rotatable knob means; and
a ramped element means in cooperation with the rod assembly;
wherein the ramped surface means and the ramped element means are adapted to engage each other to move the rod assembly means to selectively allow the lever portion means to move between the shift states.
