A double clutch assembly includes a first clutch assembly and a second clutch assembly. The first clutch assembly includes a cylinder (21), a driver assembly, comprising a control member (11), a driver (1), and a driver shaft (9), wherein the control member (11), the driver (1), the driver shaft (9) and are configured to rotate concentrically together and a follower (2). The cylinder (21) is connected to the driver shaft (9). The rotation of the cylinder (21) causes the driver shaft (9) to engage with or disengage from the follower (2). The second clutch assembly includes an actuating assembly and a coupler (3). The coupler (3) relates to and is configured to rotate concentrically with the driver assembly. The actuating assembly is operably connected to the coupler (3) and is configured to move the coupler (3) causing the coupler (3) to disengage from or engage with the follower (2).

A window vent stop for use in a sliding sash window assembly 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 is a spring for 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 ispositioned between the underside of a lip on said housing and the flexible member.

In a door lock, a locking mechanism includes an outer wheel, an inner wheel disposed inside the outer wheel and operable to rotate relative to the outer wheel, a clutch member disposed in the inner wheel and normally biased to radially extend from the inner wheel into the outer wheel to interengage the inner and outer wheels, and an arm plate sleeved around the inner wheel. When the inner wheel rotates in a first direction, the arm plate is driven by the inner wheel to actuate the deadbolt. When the inner and outer wheels are interengaged, the inner wheel drives the outer wheel by rotating in a second direction. When the inner wheel disengages from the outer wheel, rotation of the inner wheel in the first or second direction is idle relative to the outer wheel.

A lock device comprising an input member rotatable about an input axis; an output member rotatable about an output axis; an electromechanical coupling device configured to adopt an uncoupled state, where rotation of the input member about the input axis is not transmitted to a rotation of the output member about the output axis, and a coupled state, where rotation of the input member about the input axis can be transmitted to a rotation of the output member about the output axis; an electric control system configured to control the coupling device to switch between the uncoupled state and the coupled state; and a sensor in signal communication with the control system, the sensor being configured to generate a position signal indicative of a position of the output member about the output axis. A lock system comprising a lock device is also provided.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, an adjustment mechanism, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The adjustment mechanism includes a compression spring, a central cap for receiving the pin and roller therethrough, and a nut for adjusting the load on the compression spring. The bolt is moveable between a first, closed position, in which the pin and roller are engaged with the bolt, and a second open position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load, as adjusted by the adjustment mechanism, is provided on the bolt to disengage the pin and roller from the bolt.

An electromechanical lock includes a lever coupled with a locking mechanism configured to receive mechanical power from an user, and to output the mechanical power to mechanically disengage the locking mechanism provided that a support of the fulcrum is in an open position, and a return mechanism for the support of the fulcrum including a reset spring whose other end is configured to, during the reception of the mechanical power from the user, move past the support of the fulcrum with the mechanical power outputted by the lever, and, finally, force the support of the fulcrum with the mechanical energy outputted by the return spring through the lever back to a locked position.

An arrangement (10) for a lock device (88a, 88b), the arrangement (10) comprising an input member (12, 106); a coupling member (26) movable between an uncoupled position (34) and a coupled position (80); an electromechanical actuator (28) comprising an actuating member (42) linearly movable between an uncoupling actuating position (44) and a coupling actuating position (78); and a torsion spring (30) having a first leg (62) and a second leg (64) movable away from each other against a deformation of the torsion spring (30), wherein the actuating member (42) is arranged to engage the first leg (62) and the second leg (64) is arranged to engage the coupling member (26) when the coupling member (26) is in the uncoupled position (34) and the actuating member (42) moves from the uncoupling actuating position (44) to the coupling actuating position (78). A lock device (88a, 88b) comprising an arrangement (10) is also provided.

A door handle with a door-side output shaft 17 and a handle 10 facing away from the door, said output shaft and handle having a common rotational axis 2 and being connected via an electromechanical clutch, may be particularly compact and may have a particularly low energy intake for shifting the clutch by providing the output shaft 30 with a recess 31 on the side facing towards the handle 10, in which a coupling element 40 is displaceably mounted; by providing the door handle 1 with a receiving area 51 for the coupling element 40 opposite to the recess; and by arranging a linear drive in the handle, the linear drive acting on the coupling element 40 in order to move the coupling element 40 in the axial direction so far out of the recess that the coupling element engages both into the recess 31 as well as into the receiving area 51 in order to close the clutch, and the coupling element is moved out of the receiving area 51 back into the recess 31 in order to open the clutch.

Emergency access device for a vehicle opening leaf, including: a graspable pull rod that is movable between a retracted position and a deployed position; a retention needle that is movable transversely to the pull rod between a position for blocking the pull rod in its retracted position and a position for releasing the pull rod; an electric ejector designed to release the pull rod; a mechanical ejector designed to release the pull rod; the pull rod including an oblique path designed to cause the retention needle to move from its blocking position to its releasing position during a movement of the pull rod in translation.
