The invention relates to a detection device for detecting mechanical functional states of a motor vehicle lock, in which at least two binary signal outputs are provided which define a logical state of the detection device through the respective electrical potentials present there. It is proposed that the functional state of the motor vehicle lock is determined on the basis of the logical state of the signal outputs and of the electrical resistance between the predetermined signal outputs.

An electromotive drive for motor vehicle applications, in particular for applications for and in a motor vehicle lock. For this purpose, the drive is equipped with an electric motor, a drive disk which can be actuated by the electric motor and can be rotated about an axis, and at least one spring assigned to the drive. The spring transmits a force to the drive disk which aids the drive within the scope of the invention.

A driving assembly of an electronic lock includes a circuit board, a motor, and an actuating cam. The abutting plate has a stopper portion and an accommodating opening. The actuating cam rotate into the accommodating opening so as to drive the abutting plate moving back and forth in a straight line. A latch assembly includes a locking column, and a buckling slot is provided at an outer periphery of the locking column. The stopper group includes a tongue pillar, a first resilience component and a tongue bolt. The tongue pillar is inserted in the buckling slot. The abutting plate moves back and forth that makes the stop portion to selectively block the tongue bolt.

The invention discloses a door opener for a door having a wing pivotally mounted to a door frame, said door opener comprising: a main body; a door opener latch hingedly mounted in the main body and pivotable between a closed position and an open position; a blocking member that is displaceable from a locking position into a release position and back, the blocking member in its locking position forming a stop for the door opener latch in the closed position to prevent pivoting of the door opener latch into the open position, and the blocking member in its release position being so far offset from the door opener latch that the door opener latch may be pivoted from the closed position to the open position and back without any restriction of movement by the blocking member; and an actuator coupled with the blocking member for releasing or locking the door opener latch.

The actuator comprises a motor having a rotatable shaft supporting a worm thread, and a spring member having two end portions is provided, wherein a first end portion of the spring member engages with the worm thread in order to displace the spring member linearly in the direction of extension of the rotatable shaft by rotating the worm thread, and wherein a second end portion of the spring member is coupled with the blocking member.

A door bolt structure of an electronic device includes a door frame, a door panel, and a resilient metallic wire. The door panel is movably disposed at the door frame and provides a hermetic seal to the door frame. The two ends of the resilient metallic wire are connected to the door panel. The resilient metallic wire bends to form hook portions which protrude from the edge of the door panel. When the door panel provides a hermetic seal for the door frame, the hook portions are engaged with an inner edge of the door frame. When pulled, the resilient metallic wire drives the hook portions to separate from the door frame, thereby allowing the door panel to move relative to the door frame.

A window vent stop for use in a sliding sash window or a sliding door assembly. The vent stop has a housing adapted to be disposed in a recess in the non-movable sash member. This housing includes a cavity with a bottom plate therein. The tumbler has at least one pivot for pivotally securing the tumbler to the housing for movement between an extended position, to prevent movement of the sliding member and a retracted position, to allow movement of the sliding member. Also within the housing the tumbler is formed with a plastic member for selectively biasing the tumbler. The housing has one or more flexible members extending from the end walls of the housing that secure the housing to an opening in a window sash when a portion of the window sash is positioned between the underside of a lip on the housing and the flexible member.

A locking mechanism for a bored lock has a lock chassis, a locking element, a motor housing, a reversible electric motor, an auger, and a spiral lock spring disposed between the locking element and the motor. The motor may drive the auger in a first or second rotational direction to move the spring towards/away from the motor to reduce/increase spring force on the locking element, thereby moving the locking element to an unlocked/locked position. One of the locking element and motor housing has a projection while the other has a guideway for slideably receiving the projection. The guideway prevents rotation of the locking element with respect to the motor as it moves between locked and unlocked positions. The projection and guideway are interlocked to prevent disassembly of the locking element and motor housing.

A lock (100) comprising a plurality of buttons (111), each button (111) having an axis along which each of the buttons (111) may be axially pressed between an un-pressed position and a pressed position, a locking plate (120), an actuator (114) configured to drive the locking plate (120): a locking mechanism (122) having an unlocked and a plurality of locked states, the plurality of locked states corresponding to different selections of buttons (111) having been pressed into their pressed positions; and a latch (117); in which, when the locking mechanism (122) is in the unlocked state, the locking plate (120) can be driven by the actuator (114) from a locked position into an 10 unlocked position so as to disengage the latch (117) and unlocking the lock (100), but when the locking mechanism (122) is in one of the locked states, the locking mechanism (122) prevents the locking plate (120) being moved by the actuator (114): the lock (100) further comprising a decoupling mechanism (200) by means of which the actuator (114) can drive the locking plate (120), the decoupling mechanism (200) being arranged to decouple the actuator (114) from the locking plate (120), so as to reduce any feedback indicative of which of the unlocked states the locking mechanism (122) is in passing from the locking plate (120) to the actuator (114). In one example, the decoupling mechanism (200) comprises a driven member (201) driven for motion by the actuator (114), a first resilient member (202) connecting the driven member (201) with the locking plate (120) and a second resilient member (203) connecting the locking plate (120) to a fixed member fixed relative to a housing of the lock (100); and in which the first (202) and second (203) resilient members each have a spring constant, with the spring constant of the first resilient member (202) being greater than the spring constant of the second resilient member (203).
