The pins are repulsed by a magnetic plate to cause the operating plate to be coupled to the stationary plate and thereby lock the locking device when there is no card key in a key insert slot. However, when there is a card key in the key insert slot, the pins are repulsed by the card key toward the magnetic plate to cause the operating plate to be separated from the stationary plate but to be coupled to said movable plate and thereby open the locking device.

  • Patent number: 5575516
    Abstract: A fastening mechanism for a handle on a cooking utensil should also have a releasable design for certain uses, for example, when the cooking utensil is heated up in a closed oven. A release and subsequent reconnection of a handle thereby should be done quickly and without effort, and the fastening mechanism for the handle moreover should be easy to manufacture. The fastening mechanism uses for this purpose an operating piece, which can be adjusted transversely with respect to the longitudinal extent of a handle piece in such a fastening mechanism. During the handling of which operating piece, a locking of the handle piece on a holding piece is released, which handle piece is covered by the handle piece and is connected to the cooking utensil. A renewed slipping over of the handle piece occurs against a light resiliency resulting from a transfer slope on a spring piece which also is used for the locking.
