A housing locking apparatus includes a shell, a cover, a fixing member, a blocking member and an operation member. The shell includes an abutting portion protruding inside of the shell and a restriction member protruding outside of the shell. The cover includes a covering plate and a sidewall protruding from the covering plate. The sidewall defines a restriction hole and abuts against the outside of the shell. The restriction member is movably received in the restriction hole. The fixing member is attached to the covering plate. The blocking member and the operation member are both rotationally attached to the fixing member. An end of the blocking member abuts against the abutting portion. The operation member rotates around the fixing member at a first direction to press the blocking member to rotate to position the end of the blocking member between the covering plate and the abutting portion.

A fenestration system is disclosed. In some examples, the fenestration system includes one or more movable window sashes and a toggle assembly. In some examples, the toggle assembly operates to limit the degree to which the window sashes are opened or otherwise moved relative to one another. In some examples, a window sash may be opened a designated amount before the toggle assembly operates to obstruct it from being further opened.

A reversible apparatus for a conventional pocket door has a sliding-handle mechanism and a handle cavity sized to facilitate human operation. Moving parts are contained in a cartridge, and remain assembled, independent of the configuration of the apparatus for doors that close from left to right, or doors that close from right to left.

A pressing type latch device includes a seat, a pivotal seat mounted in the seat, and a handle having a grasping portion pivotably connected to two eccentric locations of the pivotal seat, such that a greater operational height can be formed when the handle is lifted. When the latch device is in one of a plurality of retainable open positions or a retainable closed position, the grasping portion of the handle can be moved to a position to lift the pivotal seat, such that the grasping portion of the handle lies flush with the pivotal seat. On the other hand, when the grasping portion of the handle is lifted to move the pivotal seat downward, the handle and the pivotal seat can rotate freely. Since the latch device includes a closed position and a plurality of open positions, the latch device can be installed and used more easily.
