    • A trimmer blade assembly comprising a blade within a housing is provided. The housing includes a wall for propelling cut vegetation away from the blade assembly. The blade assembly may also include a ridge on the housing for further propulsion of cut vegetation away from the trimmer blade. The present blade cuts vegetation more efficiently since cut vegetation will generally be propelled away from the blade by the perpendicular wall and ridge.
    • 提供了一种在壳体内包括刀片的修剪刀片组件。 壳体包括用于推动切割植被远离叶片组件的壁。 刀片组件还可以包括壳体上的脊,用于进一步推动切割的植被远离修剪刀片。 由于切割的植被通常将被垂直的墙壁和脊部从叶片推开,所以目前的叶片更有效地切割植被。

    • A locking fastener assembly comprising a nut and a washer. The nut and washer each have opposed load bearing surfaces which include a series of annularly extending, slightly inclined faces forming shallow undulations around each surface. The load bearing surface on the nut is generally spherically convex and the load bearing surface on the washer is generally spherically concave. The nut rotates as it is installed while the washer is prevented from rotating so that the undulating bearing surface on the nut slides over the undulating bearing surface on the washer against ever increasing resistance until the assembly is properly seated and the nut is effectively prevented from counter-rotating by interference between opposed, inclined faces. A concave clamping surface is formed on the outer end of the washer on a radially extending flange. The flange flexes when the assembly is installed and resiliently urges the washer against the nut.
    • 一种锁定紧固件组件,包括螺母和垫圈。 螺母和垫圈各自具有相对的承载表面,其包括一系列环形延伸的稍微倾斜的表面,其在每个表面周围形成浅的起伏。 螺母上的承载表面通常是球形凸起的,并且垫圈上的承载表面通常是球形凹形的。 螺母在安装时旋转,同时防止垫圈旋转,使得螺母上的起伏的支承表面在垫圈上的波动支承表面上滑动,抵抗不断增加的阻力,直到组件正确就位并且螺母被有效地防止 通过相对的倾斜面之间的干涉来旋转。 凹形夹紧表面形成在垫圈的径向延伸凸缘上的外端上。 当安装组件时,凸缘弯曲并弹性地将垫圈推向螺母。
