    • An impact instrument for delivering an impulse to an object. The impact instrument may include an impact surface for contacting the object and an elongated member extending from the impact surface that terminates in an end. The elongated member may include a grasping region in the vicinity of the end. When the instrument is grasped within the grasping region, the center of percussion of the instrument preferably coincides with the impact surface. The instrument may also contain pivoting grasping member disposed on the elongated member. A cavity is preferably formed between the grasping member and the elongated member and may contain compressible material. The grasping member may rigidly contact the elongated member at an ideal pivot point. The grasping member is preferably adapted to pivot with respect to the elongated member at the ideal pivot point. The pivoting of the grasping member preferably increases the amount of impulse delivered to an object, decreases vibration experienced by the user of the instrument, and reduces counter-rotational forces imparted from the instrument to the user. The impact instrument may be a hammer, ax, golf club, tennis racket, or similar device.
    • 用于向物体传递冲击的冲击仪器。 冲击仪器可以包括用于接触物体的冲击表面和从冲击表面延伸的细长构件,其终止于末端。 细长构件可以包括在端部附近的抓握区域。 当在把持区域内抓握仪器时,仪器的敲击中心优选与冲击表面重合。 仪器还可以包括设置在细长构件上的枢转抓握构件。 优选地,在夹持构件和细长构件之间形成空腔,并且可以包含可压缩材料。 抓握构件可以在理想的枢转点处刚性地接触细长构件。 抓持构件优选地适于在理想枢转点处相对于细长构件枢转。 抓持构件的枢转优选地增加输送到物体的冲击量,减少仪器使用者所经历的振动,并减少从仪器向用户施加的反向旋转力。 撞击器械可以是锤子,斧头,高尔夫球杆,网球拍或类似装置。
