    • An improved driving element, fastener placement system, method of fastening and combination of fastened workpieces are disclosed which include a generally U-shaped, staple-like fastener having a pair of legs spaced from each other by a crown which transversely extends between the upper ends of the legs to connect the legs to each other adjacent their upper ends and space the upper ends of the legs apart by a given distance. Each of the legs also has an opposite lower end which enter the respective workpieces which are to be fastened together. The fastener is positioned with the lower end of one leg in contact with one of the workpieces and the lower end of the other leg in contact with the other workpiece, and the fastener is then forcibly driven into the respective workpieces by a driving element which acts upon the crown in a manner to attempt or tend to shorten the distance between the upper ends of the legs by bending the crown and countersinking the legs and/or crown into the workpieces. This results in continuing forces which tend to continue to urge the respective workpieces together after the fastener has been driven.
    • 公开了一种改进的驱动元件,紧固件放置系统,紧固和紧固工件组合的方法,其包括大致U形的钉状紧固件,该紧固件具有通过冠部彼此间隔开的一对腿部,该冠部在上端 的腿部将腿部彼此相邻连接,并且将腿的上端分开一定距离。 每个腿还具有相对的下端,该下端进入要紧固在一起的各个工件。 紧固件定位成使得一个腿的下端与其中一个工件接触并且另一个腿的下端与另一个工件接触,然后通过驱动元件将紧固件强制地驱动到相应的工件中,该驱动元件作用 通过弯曲冠部并将腿部和/或冠部锪孔到工件中,尝试或倾向于缩短腿部上端之间的距离。 这导致在紧固件被驱动之后倾向于将相应工件继续推动在一起的连续的力。
