Fenestration systems and associated methods include use of a lock assembly having a housing, a cam gear, a reversal gear, and one or more catches. Various aspects relate to enhanced locking/security, including repeatability and overall efficacy.

A lock, a fitting and a strike plate, in addition to a closing device for sliding doors, allow frontal or lateral locking of a sliding door. Further a sliding door system has a closing device.

Elevator lintel door lock safety devices having a frame mountable to a lintel, a lintel door lock fixed to the frame and having a first lock element rotatable relative to a second lock element, a contact plate fixed to the first lock element and moveable therewith, the contact plate having at least one contact attached thereto, a contact receiver attached to the frame and part of a safety chain, the contact receiver having at least one contact receiver aperture arranged to receive a respective contact of the contact plate, and a blocking element pivotably mounted to the frame wherein a portion of the blocking element is moveable between (i) a first position to prevent the at least one contact from engaging with a respective contact receiver aperture and (ii) a second position that allows the at least one contact to engage with the respective contact receiver aperture.

The present invention discloses a motored locking mechanism, comprising a motor, two groups of transmission mechanisms that are arranged mirror symmetrically and two output components that are arranged mirror symmetrically, wherein the transmission mechanisms transfer power of the motor to the output components, wherein the motor is provided at an output end with a driving gear, wherein the driving gear is attached to an output shaft of the motor. The transmission mechanisms on two mirror sides are controlled by a common motor so the volume is smaller with a simpler structure. Regarding both sides of the lock, the transmission mechanism of one side is driven wherein the other side not. Thus, two unrelated systems are driven by a single motor.

The present invention discloses a cylinder and a control component and relates to the field of locks, comprising two mirror-symmetric cylinder mechanisms which jointly drive a latchbolt control ring. The present invention enables equal operations on both sides of a door, and that the separate operation on both sides of the door does not interfere with each other. Furthermore, only one cylinder is required, which simplifies the structure and a single motor realizes a not-interfered alternating output on both sides of the door.

A window vent stop for use in a sliding sash window or a sliding sash door assembly. The vent stop includes a housing and a tumbler. The housing is adapted to be disposed in a recess in a rail or stile of the window/door. This housing includes a cavity with a bottom wall 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. The tumbler is formed with a protruding spring member for selectively biasing the tumbler. The housing has one or more flexible members extending from each of its end walls to secure the housing within the opening in the sash member.

Fenestration systems and associated methods include use of a lock assembly having a housing, a cam gear, a reversal gear, and one or more catches. Various aspects relate to enhanced locking/security, including repeatability and overall efficacy.

The present invention discloses a lock that does not distinguish between public and private spaces and relates to the field of locks, comprising two sub locking systems which have the same structure, wherein the two sub locking systems are arranged mirror symmetrically on two sides. It can be optionally installed on both spaces where privacy is needed and a change of the entire lock is not required, such that all designs of an indoor layout and different requirements for design logics regarding doors are adjusted to, that a locking on both sides in an electrically controlled manner is possible, that rotation of a cylinder on both sides is prevented, and that an unlaching movement on both sides in an electrically controlled manner is possible.

Hardware for a lift glide door assembly and lift glide window assembly provides ease of opening with an operational opening assist that urges the door or window to an open position on operation of an opening handle by use of a cable drive system. A lock mechanism actuates a lock pin, blocks opening gear mechanisms from operating and extends a security bolt for locking. A guide blade is provided for assisting the door during opening or closing operations.

The present invention relates to the field of locks and relates to a latchbolt mechanisms, comprising a rotatable latchbolt (16) and an elastic element (17), wherein the rotatable latchbolt (16) is fixedly mounted on a rotatable pin shaft, round which the rotatable latchbolt rotates. Therefore, a rotational unlocking and locking is enabled and is suitable not only for hinged doors, but also for sliding doors. By a rotary movement, actions of door opening and closing are avoided in a usual case.
