ABSTRACT:
In a mechanical hand amusement device there is provided a handle with a movable grip member joined to an elongated arm, and a hand member having a fixed thumb and four flexible finger members joined to a shaft housed within and capable of moving along the length of the elongated arm. A spring, one end of which is connected to the arm, and the other end of which is connected to the shaft, holds the shaft in tensioned relationship with the arm to induce sliding of the shaft along the arm when a release mechanism is activated. In addition, the grip member and the hand member are connected by a continuous string which further winds through two pulleys. One pulley is connected to the arm through a slit in the shaft, and the other pulley is connected to the shaft. When the release button is pushed, the shaft extends from the arm and the length of string between the respective pulleys is decreased but the length of string between the pulleys and the ends of the device is increased. Again, the grip member may be squeezed in this extended position to activate the flexible hand. Thus, with the shaft in either the non-extended or extended position, the grip member is capable of operating the hand member.
