摘要： A safety net attached to the doors at a pumping station to cover the open well when the doors are open. The safety net has a plurality of strips in a first direction and a substantially perpendicular plurality of strips in a second direction. The strips are connected where there are intersections. The edges of the strips have attachment means for connection to the doors, or alternately for connection to the frame about the top of the well. When the doors are opened, the safety net is in place and when the doors are closed, the safety net is suspended in the open well. The safety net may also be connected to a single door for those wells which have only a single door as a cover.

摘要： A switch lockout mechanism for a power tool includes a handle housing for gripping by a power tool operator. The handle housing is generally elongated in a direction corresponding to the gripping axis of a power tool operator. A switch is attached to the housing and is actuatable between an "on" position and an "off" position. A locking member is rotatably or pivotally attached to the housing. The locking member is rotatable about an axis that generally extends in the same direction as the handle housing in an elongated direction. The locking member has a first rotatable position wherein the switch is locked in its "off" position, and a second rotatable position wherein the switch is actuated to its "on" position. An actuating member allows a tool operator to move the locking member between its first and second positions.

摘要翻译：用于电动工具的开关锁定机构包括用于由电动工具操作者夹持的手柄壳体。手柄壳体通常在与电动工具操作者的夹持轴线相对应的方向上伸长。开关附接到壳体并且可以在“开”位置和“关”位置之间起动。锁定构件可旋转地或可枢转地附接到壳体。锁定构件可绕轴线旋转，所述轴线通常沿与手柄外壳沿长度方向相同的方向延伸。锁定构件具有第一可旋转位置，其中开关锁定在其“关闭”位置，以及第二可旋转位置，其中开关被致动到其“接通”位置。致动构件允许工具操作者在其第一和第二位置之间移动锁定构件。
