摘要： A door- or window sash which is pivotable relative to a door- or window frame between open and closed positions can be releasably affixed to the frame in the closed position in response to turning of a handle which can shift an elongated carrier relative to the frame between two spaced-apart end positions. The carrier supports a series of longitudinally spaced-apart projections each of which fully engages a complementary retainer on the sash during different stages of movement of the handle from one end position to the other end position. The arrangement may be such that the projection nearest to the handle is first to engage the complementary retainer on the sash, that the projection which is adjacent the nearest projection is next to engage the corresponding retainer, and so on. A safety device can be provided to releasably lock the carrier in the other end position.

摘要： A casement window wherein the sash is pivotable in the frame about a vertical axis has a self-locking crank drive which pivots the sash between open and closed positions by way of a pivotable lever, a link which is coupled to the lever, and an actuator which is movably installed in the sash, which is coupled to the link and which forms part of a locking-unlocking mechanism for the sash. The first stage of rotation of the crank drive in order to pivot the sash from closed position involves a displacement of the actuator which ensures that the sash is unlocked, and further rotation of the crank drive results in pivoting of the sash to the open position. If the direction of rotation of the crank drive is reversed, the sash is moved to the closed position before the actuator is caused to lock the sash to the frame. A blocking device for the actuator is operated by the frame to release the actuator for movement to its operative position shortly before the sash reaches the closed position. To this end, a mobile blocking element of the blocking device is installed in the sash and is displaced by the frame before the sash reassumes its closed position whereby the blocking element releases the actuator which is held in the inoperative position while the sash is held in an open or partly open position.

摘要翻译： 窗扇，其中窗框可围绕竖直轴线在框架中枢转，具有自锁曲柄驱动器，该自锁曲柄驱动器通过可枢转的杆，连接到杠杆的连杆和致动器的致动器在打开位置和闭合位置之间枢转窗框 其可移动地安装在窗框中，窗框联接到链节并且形成用于窗框的锁定解锁机构的一部分。 曲柄驱动器的旋转的第一阶段是为了使窗框从关闭位置枢转，包括致动器的位移，确保了窗框被解锁，并且曲柄驱动器的进一步旋转导致窗扇转动到打开位置。 如果曲柄驱动器的旋转方向相反，则在致动器将窗框锁定到框架之前，窗框移动到关闭位置。 用于致动器的阻挡装置由框架操作以释放致动器以在窗框到达关闭位置之前不久移动到其操作位置。 为此，阻挡装置的移动阻挡元件安装在窗框中，并且在窗框重新开启其关闭位置之前被框架移位，由此阻挡元件释放保持在非操作位置的致动器，而窗扇被保持在 打开或部分开放的位置。
