  • Publication number: 20090095037
    Abstract: A key alignment system for safety interlock switches uses alignment holes, and alignment pins to compensate for misalignment between a body assembly and a key assembly. The misalignment is often due to normal wear and tear or outright abuse of a gate or other movable member that should be safely interlocked. The key is fixed to a floating plate connected to a mounting plate by a suspension. The alignment pins and holes on or in a fixed alignment assembly and the floating plate can move the floating plate into a position such that the key enters the key hole. Some embodiments incorporate the fixed alignment assembly into the body assembly. The normal function of a keyed safety interlock wherein the key can be caught and held or released is preserved and enhanced by compensating for misalignment.

  • Publication number: 20080223094
    Abstract: A lock key comprises a key blank (20) that has a gripping part (20a) and a key bit part (20b). A circuit board (34) that has mounted thereon electric circuits and a key contact part (35) connected electrically to the electric circuits are accommodated in a circuit board cradle (30) made of electrically non-conductive material. The circuit board cradle is fitted to the key blank. The placement of a circuit board and electric contact conductor in an electrically non-conductive material makes possible rational manufacture of the arrangement. Because the circuit board cradle made of electrically non-conductive material can be fixated in the key blank it is possible to position the electric contact conductor precisely, thereby ensuring a reliable electric contact function.

    Abstract: A key operating mechanism is embodied in an elongate housing having an axially disposed shaft defining a helical groove. A shaft end is provided with a key to which rotation is imparted by an actuator slidably disposed on the shaft. A drive member of the actuator cooperates with the helical groove in the shaft to impart rotation to the latter and may serve as a detent to prevent actuator movement. Spring elements, oppositely disposed from the actuator, serve to return the actuator to a neutral or static position wherefrom rotation in either direction may be imparted to the shaft. A thumb operated control button of the actuator slides within a housing defined slot during operation of the mechanism.
