Abstract
Disclosed is a stabilization system for an apprentice pantographic data entry device having at least six pivot axes of rotation. The stabilization system is formed of a plurality of pivoted linkages forming at least one parallelogram which support weights counterbalancing the arms of apprentice pantographic data entry device. The linkages and a series of pulleys rotate the counterweights in response to the movement of the arms. In a first embodiment, a pair of parallelograms are symmetrically disposed about the first arm. In a second embodiment, a single parallelogram is disposed on one side of the arms. In a third embodiment, a single parallelogram is disposed in a plane defined by the first and second arms.
Claims11
A stabilization system for an apprentice pantographic daty entry device having at least six axes of rotation, said apprentice pantographic data entry device including a first vertical axis, a second horizontal axis, a first arm pivoted at one end thereof in a vertical plane, said one end of said first arm being located at the point of intersection of said first and second axes, a third horizontal axis at the other end of said first arm, a second arm pivoted in said vertical plane at one end thereof, said second arm being pivoted about the point of intersection of said first arm and said third axis,
- a fourth axis at the other end of said second arm;
- a third arm pivoted in a plane perpendicular to said vertical plane at one end thereof, said third arm being pivoted about the end of intersection of said second arm and said fourth axis, and a polyarticulated aspirator and a gun connected to the other end of said third arm, said stabilization system comprising:
- at least one partial parallelogram composed of pivoted linkages, said parallelogram being parallel to a plane defined by said first and second arms;
- a plurality of counterweights attached to said pivoted linkages;
- angle transmitting means incorporating said pivoted linkages and adapted to transmit the rotation of said third arm about said fourth axis to a first one of said counterweights, wherein said angle transmitting means further includes pulley means transmitting the rotation of said third arm about said fourth axis to said first one of said couterweights rotatable about a first one of said linkages which is parallel to said first arm.
