Abstract
A dual brake pedal lock mechanism includes a pair of lock members individually mounted on a shaft for limited pivotal movement relative thereon. The shaft has a handle connected thereto for respectively bringing the pair of lock members into engagement with racks of teeth of a pair of brake pedals so as to retain them in respective depressed, brake-engage positions. The mountings of the pair of lock members permit one brake pedal to be depressed further than the other without effecting disengagement of the other brake pedal from its associated lock member.
Claims5
In a combination including a pair of brake pedals mounted in side-by-side relationship to each other for pivotal movement between brake-release and brake-engage positions and each including an arm provided with a rack of teeth, and a pedal lock mechanism including a pair of lock members pivotally mounted for selective movement between pedal-release positions wherein they are free of said rack of teeth and pedal lock positions wherein they engage said rack of teeth for locking said brake pedals in their brake-engage positions, an improved pedal lock mechanism, comprising:
- a pivotally mounted shaft movable between first and second positions corresponding to said pedal-release and pedal-lock positions;
- first and second connection means respectivley connecting said pair of lock members to said shaft for pivotal movement therewith and for limited swivel movement relative thereto and to each other;
- said first and second connection means respectively including first and second biasing means acting between the shaft and said pair of lock members and urging the latter toward their pedal-lock positions for thereby establishing a pair of one-way resilient connections permitting the pedals to be either independently or simultaneously locked in and simultaneously released from their brake-engage positions.
A lock mechanism for selectively locking a pair of brake pedals in depressed brake-engage positions, comprising:
- an actuator assembly including a pivotally mounted shaft;
- a handle rigidly fixed to the shaft for moving the latter between pedal-release and pedal lock positions;
- a pair of pedal lock members, each having a first end swivelly mounted on said shaft and a second end adapted for locking engagement with a respective one of a pair of depressed brake pedals when the lever is in its pedal lock position;
- and a pair of means respectively connected between said shaft and said pair of pedal lock members for establishing a predetermined limited amount of swivelling of the latter relative to the shaft and, hence, to each other;
- and said pair of means including resiliently yieldable means urging said pair of pedal-lock members toward positions corresponding to said pedal-lock positions.
