Heat regulating mechanism for automotive heating and air conditioning systems

A heat regulating mechanism for automotive air environment regulating systems, such heat regulating mechanism comprising

• a control lever having means for connecting such control lever to a heat control device,
• first pivot means for pivotally supporting such control lever for swinging movement about a first pivot axis,
• a manually operable operating lever having an end portion with manually engageable means thereon movable along a predetermined path,
• such operating lever having a second portion with a generally longitudinal guide slot therein,
• second pivot means extending through such guide slot and supporting such second portion of such operating lever for a combination of pivotal and sliding movement,
• such second pivot means being disposed along a second pivot axis which is parallel with but spaced from such first pivot axis,
• a stationary guide track near the end portion of the operating lever,
• such operating lever having a follower thereon for slidably engaging and following the guide track,
• and pin and slot elements forming an operative connection between such operating lever and such control lever,
• such pin element being on one of such levers while such slot element is on the other of such levers,
• whereby manual movement of such operating lever causes swinging movement of such control lever with a combination of swinging and sliding movements between such pin and slot elements.
