    摘要： A firm closure and locking device to firmly close and lock a vent window pivotally mounted and adjacent to a rigid member. The device has a body portion configured in a U-shape which fits over the edge of the vent window adjacent to the rigid member. A locking arm is pivotally mounted to the body onto a pivot element, preferably a screw-like member projecting from the body. A pressure-bearing device, such as a handle with an internal threaded receptacle portion is threadedly engaged onto the screw-like member. The handle is rotated upon the screw-like member to advance it inwards towards the body, thereby applying pressure against the locking arm intermediate the handle and the body of the locking device. When the U-shaped portion of the body is fitted over the edge of the vent window adjacent the rigid member and no pressure is applied against the locking arm, the locking arm is free to rotate about the screw-like member until it abuts against the side of the adjacent rigid member. Pressure applied against the locking arm by the rotating handle locks the locking arm against further pivotal rotation and furthermore draws the vent window into a tightly closed position preventing air seepage and wind noise.

    摘要翻译： 牢固的闭合和锁定装置，用于牢固地关闭和锁定可枢转地安装并邻近刚性构件的通风窗。 该装置具有构造成U形的主体部分，其配合在与刚性构件相邻的通风窗口的边缘上方。 锁定臂可枢转地安装到主体上的枢轴元件上，优选地是从主体突出的螺钉状构件。 压力承载装置，例如具有内螺纹插座部分的手柄，螺纹地接合到螺丝状构件上。 手柄旋转在螺丝状构件上以使其向内朝向主体前进，从而在手柄和锁定装置的主体之间向锁定臂施加压力。 当主体的U形部分装配在与刚性构件相邻的通风窗口的边缘上方，并且没有压力施加到锁定臂上时，锁定臂可以围绕螺丝状构件自由旋转，直到其抵靠 侧相邻的刚性构件。 通过旋转手柄对锁定臂施加的压力锁定锁定臂以防止进一步的枢转旋转，并且进一步将通风窗口吸入密闭位置，防止空气渗漏和风噪声。
