Abstract
Abstract The foot brake of a motor vehicle is combined with a speed control lever pivotal about mutually perpendicular axes. Pivoting about one axis causes braking while pivoting of the lever about the other axis moves it between an idling and a motor speed control position. When the lever is pivoted about the one axis into the braking position, a force is exerted upon the lever to move it from the motor speed control into the idling position, and two limit switches are arranged in the pivoting path of the lever to cause this force to be exerted upon simultaneous energization of one of the switches and de-energization of the other switch.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
An operating mechanism for a motor vehicle, comprising a foot-operated brake and motor speed control lever, the lever being mounted for pivoting about a first axis into a position to brake the vehicle and for pivoting about a second axis extending transversely to the first axis, the lever being pivotal about the second axis between an idling position and motor speed control position, a return means for moving the lever from the motor speed control position to the idling position when the lever is pivoted about the first axis into the braking position, and two limit switches for actuating the return means upon simultaneously energizing a first one of the switches and de-energizing a second one of the switches.
Claim 2
Dependent Claim
119 words
An operating mechanism for a motor vehicle, comprising a foot-operated brake and motor speed control lever, the lever being mounted for pivoting about a first axis into a position to brake the vehicle and for pivoting about a second axis extending transversely to the first axis, the lever being pivotal about the second axis between an idling position and motor speed control position, a return means for moving the lever from the motor speed control position to the idling position when the lever is pivoted about the first axis into the braking position, and two limit switches for actuating the return means upon simultaneously energizing a first one of the switches and de-energizing a second one of the switches.
Claim 3
Dependent Claim
38 words
The operating mechanism of claim 1, wherein the first limit switch is energized upon pivoting of the lever into the braking position and the second limit switch is energized in the motor speed control position of the lever.
Claim 4
Dependent Claim
25 words
The operating mechanism of claim 2, wherein the return means comprises a solenoid energized upon energization of one and de-energization of the second limit switch.
Claim 5
Dependent Claim
27 words
The operating mechanism of claim 2, wherein the return means comprises a vacuum operating cylinder actuated upon energization of one and de-energization of the second limit switch.
Claim 6
Dependent Claim
26 words
The operating mechanism of claim 2, wherein the return means comprises a pneumaTic cylinder actuated upon energization of one and de-energization of the second limit switch.
Claim 7
Dependent Claim
89 words
The operating mechanism of claim 2, further comprising a motor speed control and a transmission between the lever and the control, the control, the transmission including two elements movable in respect of each other in one relative position and locked for common movement in another relative position, the two elements being biased into locking engagement in the other relative position, and the locking engagement being releasable upon pivoting of the lever to brake the vehicle and while the lever is in a position other than the idling position thereof.
Claim 8
Dependent Claim
18 words
The operating mechanism of claim 6, wherein the two elements are linearly displaceable in respect of each other.
Claim 9
Dependent Claim
17 words
The operating mechanism of claim 6, wherein the two elements are rotatable in respect of each other.
Claim 10
Dependent Claim
28 words
The operating mechanism of claim 6, further comprising two cooperating members for providing the locking engagement, and the second limit switch is actuatable by one of the members.
Claim 11
Dependent Claim
39 words
The operating mechanism of claim 6, wherein one of the transmission element is a sleeve and the other transmission element is a rod guided in the sleeve for linear displacement of the transmission elements in respect of each other.
Claim 12
Dependent Claim
49 words
The operating mechanism of claim 6, wherein one of the transmission elements is a hollow shaft having an axial bore and the other transmission element is a shaft being rotatably journaled in the bore of the hollow shaft for rotatable movement of the shafts in respect of each other.
