Abstract
A force-displacement controller knob for use in isometric control devices provided. A controller knob component is mounted on existing control shafts and the knob itself contains a pair of compressible, resilient washers separated by and contacting a rigid washer in a chamber in the knob so that force appied in any direction on the knob will be transferred to the control shaft in a resistance ratio determined by the compressibility of the resilient washers.
Claims6
In combination with a control shaft for force controls:
- an appendage having a chamber therein for receiving the free end of said shaft;
- bifurcated compressible resilient means in said chamber for providing a selected resistance to force applied to said appendage;
- rigid means secured to said shaft end and axially and laterally engaging said resilient means for transmitting selectively lesser force to said shaft than is applied to said appendage,
- said rigid means and said resilient means in part spaced from said appendage so as to permit selected movement of said rigid means in said chamber;
- and
- means secured to said appendage for retaining said resilient means in said chamber.
