  • Patent number: 5640713
    Abstract: A finger-tip protection device for absorbing mechanical shock transferred to the finger-tip as a result of repetitive contact with a hard surface. The device includes a rigid shell having a cavity into which a finger-tip can to be inserted into it. The fore end of the shell is provided with a shock absorbing mechanism located so as to at least partially protrude from the shell in the direction of the intended contact surface. The contact surface is covered with resilient nubs functioning as a portion of the shock absorbing mechanism. In this manner, the shock transferred through the contact surface is attenuated by the shock absorbing mechanism so as to diminish the fatigue and soreness effects caused by repetitive striking of the finger-tip against a hard surface.
