Abstract
A safety interlock system for hand operated vehicle accelerator control systems is disclosed which permits a hand operated accelerator control system to be immobilized so that it cannot be activated unintentionally or accidentally by an individual operator who is not familiar with a vehicle so equipped. The safety interlock system may be selectively activated by the vehicle operator manually directly by mechanical means or remotely by means of a switch-controlled hydraulic, pneumatic or electrical activator. An indicator system is provided which indicates the status of the safety interlock system to the vehicle operator.
Claims13
A safety interlock system and hand operated vehicle acceleration control device assembly, comprising:
- a bearing block having a first aperture and a second aperture;
- a control device including a rotating shaft and a lever operatively connected to the rotating shaft at a first end portion of the rotating shaft, the rotating shaft being rotatable about a first axis for controlling vehicle acceleration, the rotating shaft being a unitary, one-piece, integral member and extending through the first aperture of the bearing block;
- an aperture formed in the rotating shaft;
- a locking member disposed in the second aperture of the bearing block and having an elongate body portion disposed along a second axis, the locking member being selectively movable along the second axis and including a lock end portion and an activation end portion, the lock end portion being adapted to be releasably received in locking engagement by the aperture, the rotating shaft being non-rotatable at the first end portion and at a second end portion of the rotating shaft when the aperture receives the locking member;
- and
- an activating device secured to the activation end portion for moving and positioning the locking member at preselected positions along the second axis.
