Abstract
Abstract An educational vehicle is provided in which the driver-student is provided with a conventional braking pedal and the passenger-teacher is provided with a braking pedal to override the driver-student braking pedal in order to effect a braking operation. Furthermore, there is provided a counter braking pedal which is employed to override the operation of the brake by the driver-student. The counter braking arrangement may involve a mechanical system provided with a mechanical advantage so constructed and arranged that the operation of the counter braking device is capable of preventing or reversing the operation of the brake by the driver-student. The counter braking operation can also be effected through an electrical or hydraulic apparatus or the like.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
196 words
An educational driving vehicle with which a passenger-teacher instructs a driver-student to drive, said vehicle comprising driver-student braking means, passenger-teacher braking means to override the driver-student braking means to effect a braking of said vehicle, and counter braking means positioned for operation by the passenger-teacher to prevent or reverse the operation of the driver-student braking means by the driver-student, the passenger-teacher braking means and the counter braking means comprising adjacent pedals spaced from but coupled to the driver-student braking means, the driver-student braking means including a pedal coupled to the pedal of said passenger-teacher braking means, a support and a rod extending from said support, the pedal of said teacher braking means being coupled to said rod, the pedal of said driver-student braking means being coupled to said rod at a position further from said support than where the pedal of said passenger-teacher braking means is coupled to said rod, both said passenger-teacher braking means and driver-student braking means being adapted to deflect said rod in substantially the same direction, the counter braking means being detachably coupled to said rod and being adapted to deflect the rod in the direction generally opposite the first said direction.
Claim 2
Dependent Claim
196 words
An educational driving vehicle with which a passenger-teacher instructs a driver-student to drive, said vehicle comprising driver-student braking means, passenger-teacher braking means to override the driver-student braking means to effect a braking of said vehicle, and counter braking means positioned for operation by the passenger-teacher to prevent or reverse the operation of the driver-student braking means by the driver-student, the passenger-teacher braking means and the counter braking means comprising adjacent pedals spaced from but coupled to the driver-student braking means, the driver-student braking means including a pedal coupled to the pedal of said passenger-teacher braking means, a support and a rod extending from said support, the pedal of said teacher braking means being coupled to said rod, the pedal of said driver-student braking means being coupled to said rod at a position further from said support than where the pedal of said passenger-teacher braking means is coupled to said rod, both said passenger-teacher braking means and driver-student braking means being adapted to deflect said rod in substantially the same direction, the counter braking means being detachably coupled to said rod and being adapted to deflect the rod in the direction generally opposite the first said direction.
Claim 3
Dependent Claim
31 words
A vehicle as claimed in claim 1 wherein the counter braking means includes means to fix the counter braking means in the vehicle by detachably bracing the same within the vehicle.
Claim 4
Dependent Claim
25 words
A vehicle as claimed in claim 2 wherein said means to fix the counter braking means includes a rigid structure including threadably extensible foot means.
Claim 5
Dependent Claim
25 words
A vehicle as claimed in claim 1 wherein said counter braking means includes a member provided with a slot in which to engage said rod.
Claim 6
Dependent Claim
26 words
A vehicle as claimed in claim 4 wherein the counter braking means includes a lever coupling the pedal of the counter braking means to said member.
Claim 7
Dependent Claim
35 words
A vehicle as claimed in claim 5 wherein the counter braking means includes a pivot supporting said lever in such a manner as to provide a mechanical advantage to the pedal coupled to said lever.
Claim 8
Dependent Claim
47 words
A vehicle as claimed in claim 6 wherein the member engages said rod at a position relative to said support such that the pedal of the driver-student braking means has a mechanical advantage which is less than that provided by said lever to said counter braking means.
Claim 9
Dependent Claim
21 words
A vehicle as claimed in claim 7 comprising spring means for spring loading said rod to a normal position of rest.
Claim 10
Dependent Claim
54 words
A vehicle as claimed in claim 1 wherein the driver-student braking means and counter braking means are so constructed and arranged as to have opposing mechanical advantages, said counter braking means including a system of levers connected so that the mechanical advantage of the counter braking means exceeds that of the driver-student braking means.
Claim 11
Dependent Claim
125 words
In a system having first and second controls selectively displaceable to effect a control operation and a connecting member interconnecting said controls whereby selective displacement of said second control is effective to displace said first control to effect said control operation, a counter control comprising a support, and a lever on said support to engage said connecting member and prevent displacement of said first control thereby to prevent said control operation, said lever including interconnected links constituting means so constructed and arranged as to provide a mechanical advantage to enable reversing displacement of said first control, said controls constituting means so connected and arranged on said connecting member that operation of said first or second controls displaces said counter control into position for operation thereof.
Claim 12
Dependent Claim
125 words
In a system having first and second controls selectively displaceable to effect a control operation and a connecting member interconnecting said controls whereby selective displacement of said second control is effective to displace said first control to effect said control operation, a counter control comprising a support, and a lever on said support to engage said connecting member and prevent displacement of said first control thereby to prevent said control operation, said lever including interconnected links constituting means so constructed and arranged as to provide a mechanical advantage to enable reversing displacement of said first control, said controls constituting means so connected and arranged on said connecting member that operation of said first or second controls displaces said counter control into position for operation thereof.
Claim 13
Dependent Claim
28 words
A counter control as claimed in claim 10 comprising a member pivoted to said lever and provided with a slot said connecting member is engaged in said slot.
Claim 14
Dependent Claim
45 words
A counter control as claimed in claim 11 wherein said connecting member is a rod and said controls include pedals connected to said rod at spaced positions, said counter control including a pedal positioned substantially closer to said second control than to said first control.
Claim 15
Dependent Claim
17 words
A counter control as claimed in claim 12 comprising means supporting said rod adjacent said second control.
Claim 16
Dependent Claim
31 words
A counter control as claimed in claim 13 wherein said support includes connected relatively extensible parts whereby the support can be detachably jammed into position for the support of said lever.
Claim 17
Dependent Claim
24 words
A counter control as claimed in claim 14 comprising a fixed claw on at least one of said parts to grasp onto said system.
Claim 18
Dependent Claim
