Two operation release system stick type parking brake

Abstract

Abstract PURPOSE: To prevent the release of a parking brake that is not subject to a driver's will, by allowing revolution in the lock release direction only when pulling a handle. CONSTITUTION: An operating lever 5 is made hollow and a lock bar 15 is inserted into the lever, the one end 15a is bent and inserted into an approx. L character-like groove 18 shaped to a pipe wall while another end 15b is mounted to a handle 6 in a revolution-free shape, the handle 6 is installed to the operatig lever 5 in a form that the handle can be displaced in the axial direction and cannot relatively be turned, the lock bar 15 or the handle 6 is energized by means of a spring 26, said L character-like groove 18 is shaped by a 1st groove 18a and a 2nd groove 18b, and the handle 6 is displaced in the axial direction to the operating lever 5, thus resulting in the revolution of the operating lever 5 only when the one end 15a of the lock bar 15 is moved to the 2nd groove 18b from the 1st groove 18a. Above-mentioned arrangement can turn the lever in the lock release direction only when pulling the handle 6, and improves safety without rotating the lever even if human bodies and bodies collide with the handle 6 under a condition that a parking brake works COPYRIGHT: (C)1979,JPO&Japio
