A door stopping mechanism for a sliding glazing patio door or like, independent in construction from the sliding glazing for which it is stopping, includes a vertical and horizontal component. The horizontal component is within the track of the door, while the vertical component is selectively attached to the sliding member. The mechanism is changeable from a locked to unlocked position by manipulation by a user at mid-height of the door, and at least one of the locked or unlocked positions is maintained by gravity.

A latching system for a door or window that includes a first snap stop member adapted to be arranged at a side edge of a leaf of the door or window, the first stop member includes a pawl rotatable about an axis perpendicular to the plane defined by the leaf; a second snap stop member adapted to be arranged at an upper edge of the leaf, the second stop member comprising a pivot translatable in a vertical direction; a handle rotatable so as to control the releasing movement of the first and second stop members, the handle being rotatable about a horizontal axis parallel to the plane defined by the leaf; and a first and a second transmission mechanism for converting a rotation of the handle into a rotation of the pawl and a translation of the pivot, respectively.

A sliding door system with a door includes a horizontally elongated member having a mounting portion with which it is mounted to a support structure, and a horizontally elongated track extending downwardly therefrom. The horizontally elongated track includes a horizontally elongated upper portion having a width, and a horizontally elongated protuberance below the upper portion having a width greater than the width of the upper portion. At least one sliding element is mounted to the top of the door and has a channel corresponding to the protuberance, and in which part of the elongated protuberance is disposed such that the sliding element is retained by and slidable on the protuberance. In some embodiments, a vertically extending rod is concealed between the front and back walls of the door and can be moved vertically in and out of an aperture in the protuberance to lock and unlock the door.

A fitting assembly has a device for securing against operating errors that has a first protrusion which can be moved relative to a second protrusion by means of a first operating rod assembly. A buffer can be provided between the end sides of the first protrusion and the second protrusion. The first protrusion can be a cylinder and/or the second protrusion can extend in an elongated manner. The fitting assembly can have an anti-lifting device with a third protrusion which prevents a lifting of the first leaf. The fitting assembly has multiple carriages and multiple sliders in order to position leaves of the window or the door into their slide position in parallel with the main plane of the window or the door. In the blocking position, the leaves can be pressed against a fixed frame of the window or the door via the fitting assembly with multiple carriages and multiple sliders, in order to reliably seal the window or the door.

A locking apparatus and method for securing a door or window comprising a substantial controllable mechanical locking mechanism that secures the sliding door or window into the receiving channel such that the locking mechanism cannot be disengaged from the receiving structure by a manual force; prevents the door or window from being lifted out of a bottom track by mere manual force; is able to report the door or window status as closed or open and as locked or unlocked to a remote user; is able to be remotely locked and unlocked using an application running on a mobile device or computer, or, alternatively by accessing a web accessible portal from a mobile device, electronic device or computer; and is manually operable by a user in the event of a power outage. A manually operated embodiment is useful for use cases in which no electric power is available.

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.

A folding door structure is provided. The folding door structure includes an upright column, upper sliding bracket and a lower sliding bracket. The upright column is hinged to the door leaves. The folding door structure further includes a first lock component. The first lock component includes a first latch mounted inside the upright column, and both ends of which are extended out from the top and bottom of the upright column to insert into the upper slide and/or the lower slide. By providing a first lock component and an upright column, a first latch can lock the position of the upright column relative to a door frame in a direction of wind pressure. Accordingly, the stress environment of the upper sliding bracket and the lower sliding bracket is improved, and the reliability and the resistance to high wind pressure of the connection mounting structure between adjacent door leaves are improved.

The tilt latch retainer apparatus and sashes incorporating the same described herein may provide a convenient construction for both initial insertion of a tilt latch assembly into a sash and/or for replacement of a tilt latch assembly in an existing sash. The tilt latch retainer apparatus and sashes incorporating the same may also provide reinforcement of the check rail on a sash including the tilt latch retainer apparatus such that the check rail including the tilt latch retainer apparatus is more resistant to mechanical deformation due to forces exerted on the check rail.

A window assembly is disclosed including a window casing; a sash assembly slidably mounted within the window casing, the sash assembly including first and second stiles extending between first and second rails; a first tilt latch assembly mounted in the first stile; a second tilt latch assembly mounted in the second stile; and a sash lock mounted to the first rail, the sash lock being operably connected to the first and second tilt latch assemblies to operate the first and second tilt latch assemblies between a latched position in which a latch member of each of the first and second tilt latch assemblies engages with the window casing assembly and an unlatched position in which the latch member of each of the first and second tilt latch assemblies is disengaged with the window casing assembly.

A lock assembly is provided for a window having a first sash and a second sash. The lock assembly comprises an elongate strip configured to be coupled to the first sash. The elongate strip has a plurality of recesses defined along a length of the elongate strip. The lock assembly also includes a lock member configured to be coupled to the second sash and operable to move along the length of the elongate strip. The lock member includes a biasing member and a coupler biased in a direction of the elongate strip by the biasing member. The coupler is configured to enter each of the plurality of recesses to selectively lock the lock member to the elongate strip.
