    • A window, with a hybrid sash counterbalance and assist mechanism, includes a frame having upper and lower sashes slidable within the frame. A sash coupling element extends between the upper and lower sashes. The hybrid sash counterbalance and assist mechanism is coupled with the sash coupling element. The window with the hybrid sash counterbalance and assist mechanism is operable in a sash counterbalance mode and in an independent sash movement mode. In the sash counterbalance mode, movement of the upper or lower sash causes converse movement of the lower or upper sash through the sash coupling element, and the movement of the upper or lower sash is assisted. In the independent sash movement mode, one of the upper and lower sashes is held static while the other of the lower or upper sashes is moved, and the moved sash is assisted.
    • 具有混合式窗框平衡和辅助机构的窗口包括具有可在框架内滑动的上下窗框的框架。 窗框联接元件在上下窗之间延伸。 混合式窗框平衡和辅助机构与窗框联接元件相结合。 具有混合式窗框平衡和辅助机构的窗口可在窗框平衡模式和独立窗扇移动模式下操作。 在窗框平衡模式中,上下窗扇的运动导致下扇形或上窗扇通过窗框联接元件的相反运动,并帮助上下窗扇的移动。 在独立的窗框移动模式中,上下窗框中的一个被保持静止,而另一个下窗或上窗框移动,并且移动的窗框被辅助。

    • A mechanism is provided for balancing and positioning a sash of a self-balancing double-hung window assembly. The mechanism may include a fixed length cable, a pulley, first and second brackets and an adjustment member. The fixed length cable may include first and second ends. The pulley may support the cable. The first bracket may include one or more attachment points relative to the first end of the cable and may include an upper end and a lower end. The second bracket may be movable relative to the first bracket and may be configured to support the sash. The adjustment member may engage and extend through the lower end of the first bracket and may be movable relative to the first bracket to cause corresponding movement of the second bracket relative to the first end of the cable.
    • 提供了一种用于平衡和定位自平衡双挂窗组件的窗框的机构。 该机构可以包括固定长度的电缆,滑轮,第一和第二支架以及调节构件。 固定长度的电缆可以包括第一端和第二端。 滑轮可以支撑电缆。 第一支架可以包括相对于电缆的第一端的一个或多个附接点,并且可以包括上端和下端。 第二支架可以相对于第一支架移动,并且可以构造成支撑窗扇。 调节构件可以接合并延伸穿过第一支架的下端,并且可以相对于第一支架移动,以引起第二支架相对于电缆的第一端的相应运动。
