A method of operating a window having a sash and a window opening limit device includes moving the sash from a closed position to a limited position. When in the limited position, the window opening limit device is in a projected position, and the sash is engaged with the window opening limit device. Moving the window opening limit device to a retracted position disengages the sash and the window opening limit device. The sash may then be moved from the limited position to an open range. When the sash is returned to the closed position, the window opening limit device automatically returns to the projected position, and the sash is disengaged with the window opening limit device.

The present application provides a door lock, comprising: a door lock, comprising: a latch head for locking a door of the top loading electrical appliance, the latch head being rotatable about an axis; and a limiting mechanism for limiting rotation of the latch head before the door of the top loading electrical appliance reaches a closed position. The latch head has a latch head unlock position and a latch head lock position, the latch head rotating between the latch head unlock position and the latch head lock position; and the limiting mechanism is arranged for limiting the latch head from rotating from the latch head unlock position to the latch lead lock position before the door of the top loading electrical appliance reaches a closed position. The door lock of the present application can lock the door of a washing machine safely and accurately.

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.

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.

Latching motion transfer arrangements may be used to raise an object up and out of the engagement with the ground or other support surface and to lower the object back onto the ground or other support surface. In one exemplary embodiment, the mechanism is caused to lift and latch by applying force in a first direction, a first time, and is caused to release and lower by applying force in the first direction, a second time.
