    • Disclosed is a mechanism to open and close windows and to automatically close doors. A roller car (9) is operated along the centre line of a primary slide track (4) causing a roller (7), affixed to the roller car (9), to exert force upon one or the other side of a slot (8) in the operating member (1) which is pivotally affixed to the primary slide track (4) at one end, to operate a secondary slide track (6) through a pivotally mounted slide (5) on the outer end of the operating member (1). The centre line of the primary slide track (4) and the centre line of the slot (8) in the operating member (1) cross each other at a substantially constant acute angle (13). When the roller car (9) is fitted with a spring which provides constant tension in a direction away from the operating member's (1) pivot point (2), it causes the closer to close automatically. The angle (13) may be varied to increase or decrease the speed and force of operation.
    • 公开了一种打开和关闭窗户并自动关闭门的机构。 滚轮(9)沿着主滑道(4)的中心线操作,使得固定到滚子(9)上的滚轮(7)在槽(8)的一侧或另一侧施加力 )在一端枢转地固定到主滑轨(4)的操作构件(1)中,以通过位于操作构件的外端上的可枢转地安装的滑动件(5)操作次滑轨(6) 1)。 主滑轨(4)的中心线和操作构件(1)中的槽(8)的中心线以基本上恒定的锐角(13)彼此交叉。 当滚轮(9)装配有一个弹簧,该弹簧在远离操作构件(1)枢转点(2)的方向上提供恒定的张力时,它使得更接近于自动关闭。 可以改变角度(13)以增加或减少操作的速度和力。
