摘要： The present invention relates to a ratchet handle having a handle assembly that is operative to turn an associated socket or the like in any one of three different turning modes. First, by oscillating the entire handle assembly about the axis of the socket, the socket is turned in conventional fashion. Secondly, by screwing or rotating either clockwise or counterclockwise the handle assembly about its longitudinal axis, a turning motion is imparted to the associated socket. Thirdly, by imparting a screw-ratchet action to the handle assembly a third mode of effectuating rotation of the socket is achieved.

摘要： The present invention relates to a safety interlock system that is associated with the door of a vehicle such as the door of a school bus, and which assures that the door of the vehicle is not inadvertently open and that certain safe conditions exist before the door can be opened. The safety interlock system comprises an electrically actuated locking mechanism, that includes a manual override, for locking the door handle of the vehicle. Forming a part of the safety interlock system along with the locking mechanism is an array of switch control means, all of which must be simultaneously actuated in order to unlock and release the door handle in order that the door be opened. First, the array of switch control means includes two independent switches that must be actuated by two separate individuals, preferably the driver of the vehicle and another individual such as the passenger or a monitor. In addition in a preferred embodiment, the array of switch control means includes at least one switch that is dependent upon and responsive to the velocity of the vehicle, and in particularly, is only actuated when the vehicle assumes a stationary position as evidenced by the brakes being applied and/or the transmission being placed in a neutral position.
