Abstract
A key interlock device includes a solenoid that holds a plunger when the solenoid is excited, and a link member that includes a shaft around which the link member is rotatable, and engages with the plunger so as to transmit a restraining force opposing an operation force of a key when the solenoid is excited. The shaft of the link member is disposed on a virtual line extending from a line of force of the operation force of the key. The key interlock device may include an engaging part through which the key interlock device is attached to a body of a steering lock device and which is disposed behind the shaft to which the operation force of the key applies.
Claims11
A key interlock device for a rotating key rotor, comprising:
- a solenoid that holds a plunger;
- and
- a link member that comprises a shaft round which the link member is rotatable, and engages with the plunger so as to transmit a restraining force opposing an operation force of a key inserted in the rotor when the solenoid is excited,
- wherein the shaft of the link member is disposed on a virtual line extending along a line of force of the operation force of the key generated in a tangential direction about a cam shaft mounted on the key rotor, and the axis of the shaft is parallel to the axis of rotation of the key rotor, and
- wherein the link member further comprises a linear arm part having a flat-shaped pressure receiving surface, said linear arm part extending between the shaft and an action surface of said cam shaft to which the operation force of the key applies and directed co-linearly along the line of force of the operation force of the key when said flat-shaped pressure receiving surface of the linear arm part engages with said action surface of said cam shaft.
