Patent ID: 8474577

Claim:
Adjustment device for maintaining a standby or release position of an operation element of a brake of a vehicle, the operation element being hinged on a fulcrum so as to rotate thereon about a hinge axis, the device comprising an articulated rod hinged on said fulcrum at a hinging end, the articulated rod being connected in rotation to the operation element, the articulated rod comprising an adjustment end, opposite the hinging end, provided with a pin having at least one adjustment hole at least partly threaded, the device comprising a push rod, operatively connected to operation means of the brake, the push rod having a threaded portion at least partly screwed into said adjustment hole of said articulated rod so as to mechanically connect said articulated rod and the operation element to the operation means of the brake, the screwing position between the push rod and the articulated rod being variable so as to change the angular released position of the operation element relative to the hinge axis, the device comprising anti-rotation means, suitable for locking the push rod against rotation, wherein said push rod comprises an operating portion suitable for rotating the push rod relative to an adjustment axis, said operating portion is arranged at a free end of the push rod, opposite a connection end of the push rod to the operation means and comprises a hexagonal section suitable for being rotated by a counter shaped wrench, wherein the anti-rotation means comprise a spring having a tab provided with a locking hole having a complementary section relative to said operating portion of the push rod so as to make the spring integral in rotation with the push rod.
