Abstract: A lock for mounting on a window jamb for selectively grasping a keeper on a window sash to secure the sash closed against the jamb, including a base for mounting to the jamb and defining an open interior space along one side of the base, a rigid plate secured to the base adjacent the open interior space and including a guide slot therein, and a motor driven drive gear pivotable within the open interior space about a first axis. A pawl is secured to the drive gear at one end for pivoting about a second axis spaced from and substantially parallel to the first axis, and includes a keeper grasping portion at its other end. A guide pin projects from the pawl and is slidably received in the guide slot whereby rotation of the drive gear moves the keeper grasping portion of the pawl between the open position and the locking position. An indicator is pivoted in the base through engagement with a drive gear pin and the pawl during movement of the pawl to selectively position one of two visually different portions at a base window opening to visually display the position of the pawl. A paddle is movably mounted within the lock base open interior space, and a switch is operably connected to the paddle provides feedback to actuate power to the motor to move the pawl to the locking position when the paddle is engaged by movement of a keeper into the base open interior space.

Abstract translation: 一种用于安装在窗口边框上的锁，用于选择性地抓住窗框上的保持器，以将窗框固定在侧板上，包括用于安装到侧柱的基座并且限定沿着基座的一侧的敞开的内部空间，刚性板 固定到邻近打开的内部空间并且在其中包括引导槽的基座，以及电动机驱动的驱动齿轮，其围绕第一轴线在开放的内部空间内枢转。 棘爪在一端固定到驱动齿轮上，用于围绕与第一轴线间隔开并基本上平行于第一轴线的第二轴线枢转，并且在其另一端包括保持器抓握部分。 引导销从棘爪突出并且可滑动地容纳在引导槽中，由此驱动齿轮的旋转使棘爪的保持器抓握部分在打开位置和锁定位置之间移动。 指示器在基座中枢转，通过在棘爪的移动期间与驱动齿轮销和棘爪接合，以选择性地将两个视觉上不同的部分中的一个定位在基部窗口开口处，以可视地显示棘爪的位置。 桨形件可移动地安装在锁定底座敞开的内部空间内，并且开关可操作地连接到桨，提供反馈以致动力到马达，以便当桨通过门把的运动进入啮合时将棘爪移动到锁定位置 基地开放的内部空间。
