  • Publication number: 20240141694
    Abstract: A door lock assembly for operating an electronic door lock module to lock and unlock a door. The door lock assembly comprises a housing extending along a central longitudinal axis from a first end to a second end, the housing comprising a peripheral wall which extends from the first end to the second end and is radially spaced around the central longitudinal axis. An interface is configured to connect the door lock assembly to the electronic door lock module for operating a lock bolt. A primary locking arrangement for locking and unlocking the door comprises a keypad for inputting information to operate the electronic door lock, and the door lock assembly comprises a secondary locking arrangement for locking and unlocking the door. At least a portion of the peripheral wall is arcuate and curves around the central longitudinal axis of the housing, and the keypad is provided on the peripheral wall and curves around the central longitudinal axis of the housing.

  • Publication number: 20220341229
    Abstract: A casement window locking assembly comprises a locking handle, a housing, a locking bar, and a coupling member to transfer movement of the locking handle to the locking bar. The locking handle is movable between a locked position and an unlocked position. The assembly comprises first and second sensors, the first sensor comprising a first handle component secured to the coupling member and a second handle component mounted within the housing in order to detect the locking handle being in a locked position, the second sensor comprising a first window component mounted in the housing and a second window component being arranged to be mounted on the window sash in order to detect the window sash being located in a closed position. Rotational movement of the handle causes translational movement of the coupling member. Also, methods of providing a window status sensor system.

  • Patent number: 11459794
    Abstract: The present invention provides a motorised door lock assembly 10 in order for a user to be able to lock and unlock a door remotely and/or with a conventional key or with a thumb turn 22 from the inside. In particular, a user may decide to continue to use a key from the outside and the thumb turn (or an internal key mechanism) from the inside but at any stage the user (or a different user) may decide to operate the lock remotely. The motorised system may be activated by a number of actuators and, in particular, the motorised system may be activated by a remote key fob, a smart phone, an internally mounted push button or an external key pad. The assembly of the present invention is able to provide a continuous choice of all three methods (where permitted) without the risk of the lock becoming stuck in one position and without the user having to perform an elaborate particular sequence to operate the lock.

  • Publication number: 20220270451
    Abstract: A sensor system to reliably alert and inform a user of the status of a window, in particular, a sensor system which reliably informs the user if the window is both in a closed position and also that the locking mechanism is in the locked configuration. There are thereby provided two independent sensor systems within the casement window handle assembly which are arranged to verify that the window handle is in the locked configuration and also that the window sash is in the closed position relative to the window frame. The casement window handle assembly comprises a first sensor for indicating the position of the window handle and this comprises a first sensor component mounted to the pivotal/movable handle and a second component fixed within the mounting base.

  • Publication number: 20210404228
    Abstract: A sash window restrictor (20) has a housing (22) which is to be let into a vertical frame member (10) of one sash (normally the upper, outer sash) of a window, at a position, say, 10 cm above the top rail of the lower sash when the windows are closed. A tab (24) is mounted in the housing and can be retracted into the housing or extended from the housing. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. With the tab extended, the lower sash (12) can be lifted until it reaches the tab (24) but no further, so that a 10 cm gap will be opened at the bottom of the window.

  • Patent number: 9309711
    Abstract: The present invention provides a locking unit 3 which is arranged to be fitted to existing casement window winding mechanisms. The winder assembly 1 comprises a winding mechanism 2 which is arranged to move the casement window outwardly or inwardly. In particular, the winder assembly 1 comprises a handle 48 which is rotated by a user in a first direction to open the window and in a second direction to close the window. The present invention provides a restrictor for restricting the opening of the casement window beyond a predetermined distance. In particular, the present invention is arranged to enable a user to wind the handle 48 until the casement window reaches the predetermined distance. The restrictor is automatically reset once the casement window is moved back or towards the closed position such that the casement window is within the predetermined restricted initial opening distance.

  • Publication number: 20140239649
    Abstract: The window restrictor (10) of the present invention may be used to limit the opening of a casement hinged window. The restrictor (10) comprises a restrictor member (12) and a latch mechanism (14). Typically, the restrictor member (12) is attached to a stile or rail (16) of the moving window pane and the latch mechanism (14) is attached to a part of the casing or frame 18 surrounding the window opening. In use, the restrictor member (12) is engaged with the latch mechanism (14) so that as the window is opened, the extent of opening is restricted by the length of the restrictor member (12). To fully open the window, the restrictor member (12) must be disengaged from the latch mechanism (14). When the restrictor member (12) and latch mechanism (14) are disengaged, they remain in such a configuration that, when the window is closed, the restrictor member (12) and latch mechanism (14) automatically re-engage to prevent the window being fully opened again.
