    • A housing assembly for a power edger that includes a housing and a door that is coupled to the housing and movable between an open position and a closed position. When positioned in the closed position, labyrinth seal members that are formed onto the housing and the door engage one another to form a labyrinth seal that inhibits dirt and debris from being expelled from the housing assembly. The housing assembly also includes a guard for shrouding a rotating blade. The guard includes a confronting portion having a leading end and a trailing end. The confronting portion is defined by an increasing radius relative to the rotary axis of the blade.
    • 一种用于动力磨床的壳体组件,其包括壳体和门,所述壳体和门联接到所述壳体并且可在打开位置和关闭位置之间移动。 当位于关闭位置时,形成在壳体和门上的迷宫式密封构件彼此接合以形成迷宫密封,其阻止污物和碎屑从壳体组件排出。 壳体组件还包括用于遮蔽旋转叶片的防护件。 护罩包括具有前端和后端的面对部分。 面对部分由相对于叶片的旋转轴线的增加的半径限定。

    • An electro-mechanical interlock and module system for an electrically powered device such as a cordless, electric lawn mower that includes a normally open interlock switch for controlling the enabling of the power circuit for the lawn mower. A key member (20) is adapted for insertion into a specially configured opening (56) in the mower housing (14) to actuate and close the interlock switch (32). With the interlock switch (32) closed, energization of the motor is controlled by a separate handle-mounted ON/OFF switch (18) in a conventional manner. In addition, a modular assembly technique is disclosed which facilitates ease of manufacturing while assuring proper alignment between the various components of the interlock system.
    • 一种用于诸如无绳电动割草机之类的电动装置的机电联锁和模块系统,其包括用于控制割草机的电源电路的启用的常开联锁开关。 钥匙构件(20)适于插入割草机壳体(14)中的专门构造的开口(56)中以致动和闭合联锁开关(32)。 在联锁开关(32)闭合的情况下,通过单独的手柄安装的ON / OFF开关(18)以常规方式控制电机的通电。 另外,公开了一种模块化组装技术,其便于制造,同时确保互锁系统的各种部件之间的适当对准。

    • A housing assembly (10) for a power edger (8) that includes a housing (40) and a door (42) that is coupled to the housing (40) and movable between an open position and a closed position. When positioned in the closed position, labyrinth seal members (56) that are formed onto the housing (40) and the door (42) engage one another to form a labyrinth seal that inhibits dirt and debris from being expelled from the housing assembly (10). The housing assembly (10) also includes a guard (52) for shrouding a rotating blade (28). The guard (52) includes a confronting portion (68) having a leading end (70) and a trailing end (72). The confronting portion (68) is defined by an increasing radius (74) relative to the rotary axis of the blade (28).
    • 一种用于动力修边机(8)的壳体组件(10),其包括壳体(40)和联接到壳体(40)并可在打开位置和关闭位置之间移动的门(42)。 当定位在关闭位置时,形成在壳体(40)和门(42)上的迷宫式密封构件(56)彼此接合以形成迷宫式密封件,该迷宫式密封件阻止灰尘和碎屑从壳体组件(10 )。 壳体组件(10)还包括用于遮盖旋转叶片(28)的防护件(52)。 护罩(52)包括具有前端(70)和后端(72)的相对部分(68)。 相对部分(68)由相对于叶片(28)的旋转轴线增大的半径(74)限定。
