Patent ID: 8499899

Claim:
A wheel chock system comprising: a first chock and a second chock for restraining movement of one or more wheels; a linkage mechanism rotatably connected to at least one of said first chock and said second chock, said linkage mechanism being adjustable to move said first chock and said second chock between a blocking position and a released position; said linkage mechanism comprising a first lever rotatably connected to said first chock and a second lever rotatably connected to said second chock; and a joint assembly comprising a pin, said pin pivotally connecting the first lever and the second lever such that said first lever and said second lever are rotatable about said pin with respect to each other; wherein said pin is discretely positionable along at least one of the first lever and the second lever such that a distance between the first chock and the second chock is adjustable; wherein said joint assembly is positionable to an over-the-center locking position to thereby maintain said first chock and said second chock in the blocking position, wherein the joint assembly passes through a center position, in which no rotational forces are placed on the joint assembly due to contact of the chocks with the one or more wheels, before the joint assembly is positioned in an over-the-center blocking position such that the chock system may remain in the blocking position due to rotational forces exerted on the joint assembly; and a handle attached to said linkage mechanism, said handle extending upwardly to allow a user to adjust said linkage mechanism while said user is in a standing position.
