    • An improved handle-to-deck coupling arrangement for a lawn mower. The coupling arrangement is provided in part by a lawn mower handle having a pair of curved distal end portions. The distal ends portions fit within a pair of channels integrally formed in a deck of the lawn mower. The end-most portions of each distal portion of the handle fit within sockets formed in a lower-most portion of the deck. This coupling arrangement serves to spread out stresses experienced by the deck over a larger area of the deck when pushing or lifting forces are exerted on the handle member by an operator. In a preferred embodiment, an anchor-type fastening assembly is included. The anchor-type fastening assembly is associated with at least one of the sockets and provides a plurality of arm portions which fit within an interior area of the end-most portion of the handle member once the end-most portion is inserted in the socket. The arm portions may then be expanded radially outwardly into contact with an inner surface wall of the end-most portion of the handle member by advancing a threaded fastener into the area defined by the socket. When completely advanced, the threaded fastener urges the arm portions radially outwardly, thus locking the end-most portion in the socket.
    • 用于割草机的改进的手柄到甲板联接装置。 联接装置由具有一对弯曲的远端部分的割草机手柄部分地设置。 远端部分配合在一体形成在割草机的甲板上的通道中。 手柄的每个远端部分的最后部分装配在形成在甲板的最下部分的插座中。 这种连接装置用于在操作者施加推力或提升力作用在手柄部件上时展开由甲板经过甲板的较大区域经受的应力。 在优选实施例中,包括锚式紧固组件。 锚定型紧固组件与至少一个插座相关联,并提供多个臂部分,一旦最后部分插入插座中,该部分就装配在手柄部件最终部分的内部区域内。 然后可以通过将螺纹紧固件推进到由插座限定的区域中,将臂部分径向向外扩展以与手柄部件的最终部分的内表面壁接触。 当完全前进时,螺纹紧固件将臂部分径向向外推动,从而将最终部分锁定在插座中。
