  • Patent number: 11542724
    Abstract: A substantially flat key blade extends from a grip portion and has a connecting portion, a major longitudinal bitting portion and a free tip portion. The substantially flat key blade has a cross-sectional profile which, in the major longitudinal bitting portion, is confined within a rectangle having a height, measured in a vertical direction, being at least 2.5 times larger than a width thereof, and extends upwards in the vertical direction from a lower edge surface to an upper edge surface along a vertical mid-plane through the rectangle. A single upper part of the key blade has a relatively small lateral width being no more than 33% of the lower relatively wide part of the key blade and extends obliquely upwards at a relatively small inclinational angle in the interval 3° to 12° relative to a vertical plane.

  • Patent number: 11536047
    Abstract: A key plug rotatable within a cylindrical bore of a cylinder lock. An upper relatively narrow part of a keyway has a small lateral width no more than 33% of the maximum width of a lower relatively wide part of the keyway and extends obliquely upwards along a first direction pointing away from a second lower side wall of a lower part and being inclined at a relatively small angle ?, in the interval 3° to 12°, relative to the vertical mid-plane. The sideways or lateral location of the upper relatively narrow part of the keyway is such that an imaginary downward extension thereof, substantially in a second direction opposite to the first direction down to an outer cylindrical contour of the key plug, will fall onto the outer cylindrical contour at a same second side of the vertical mid-plane and inside the second lower side wall of the keyway.

  • 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.

    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.
