Abstract: A power-operated vehicle door locking assembly including separate inner and outer door locking mechanisms connected with a housing assembly and an electric motorized system operable to selectively move (1) the inner door locking mechanism between an inoperative and an inner door locking position in response to inner manual electric motor energizing actuations and (2) the outer door locking mechanism between an inoperative and an outer door locking positions in response to outer manual electric motor energizing actuations. The arrangement is such that an outer manual electric motor energizing actuation without a corresponding inner manual electric motor energizing actuation causes a door latching assembly when in a door latching position to be incapable of being moved into a door unlatching position by an outer door latch releasing mechanism while at the same time the door latching assembly is capable of being moved into the door unlatching position thereof by an inner door latch releasing mechanism.

Abstract: A vehicle door latch has a rotatable forkbolt that is latched by a detent in a primary or an intermediate secondary latch position. The detent is operated via an intermittent lever that is operated by a transfer lever that is actuated by inside and outside door handles via suitable mechanical linkage. The door latch includes a locking lever that disables the door handles from operating the intermittent lever when it is in the locked position. The door latch also includes a cinching mechanism that automatically engages the forkbolt in the primary latch position when the intermediate secondary latch position is reached. The cinching mechanism includes a link that has one end connected to a cinch pawl and another end connected to the latch assembly. The link pulls on the pawl to disengage it from a cinching gear to allow the cinching gear to return to the standby or home position during an unlatching operation.

Abstract: A vehicle door latch mechanism (10) having an improved double lock assembly (34).

A catch is mounted in the actuating spindle and has a first end pivoted to the actuating spindle and a second end. A tapping plate is slidably mounted in the actuating spindle and connected to the tail piece to move therewith. When the lock is in an unlocked status, the outside handle spindle and the actuating spindle rotate synchronously, as the second end of the catch extends through the second slot of the actuating spindle into the first slot of the outside handle spindle.

Abstract: For a mobile door or container, a lock that will hold firm against shock. The lock can be opened using a keypad to turn on a motor that disengages it, or manually, using a key. To disengage the lock, a shockproofer element of the lock includes components that must first be pivoted about one axis and components that must then be pivoted about a second, different axis, usually nearly perpendicular to the first axis. The lock resists opening under shock loading because the two pivoting rotations about different axes must be made to occur in a particular sequence, and cannot occur simultaneously.

Abstract: Opening of a motor vehicle door, having a door lock, is controlled by a system which includes: a door handle pivoted on the door for displacement between a rest position and an open position and connected to the door lock through a linkage; an intermediate lever which is pivoted about a pivot axis on the door and which is connected to the linkage; and a motorized mechanism interposed between the door handle and the intermediate lever. The motorized mechanism is arranged to assume, selectively, an inhibiting state in which manipulation of the door handle has no effect on the intermediate lever, and an operational state in which manipulation of the handle causes simultaneous displacement of the intermediate lever. When this mechanism is actuated to shift it from its inhibiting state to its operational state, the intermediate lever is displaced until the door lock is unlocked.

Abstract: A vehicle door lock having a closing element component, a locking element component and an actuating element component, the latter having a component actuating element and a securing actuating element, is connected to a central locking unit for remote controlled actuation of the securing actuation element. The actuation is effected with an electric motor and, in addition, a position monitoring is provided. The electric motor, for drive by the central locking unit is a reversible polyphase stepping motor with a phase confirming stator winding and which acts via a transmission on the lock component. The locking component is designed for a drive power which is greater than the nominal power of the polyphase stepping motor when it is permanently energized. The stepping motor is driven with a working voltage which is greater than the design voltage corresponding to the drive power for the centrally operable unit. For the position monitoring, a step monitor system is used.

Abstract: A rear door latch remote control assembly for a dual-door arrangement includes a back plate mounted split-pin having a pair of operating levers pivoted thereon.

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.
