Lazy susan assembly having a rotational and vertical adjustment mechanism

In a lazy susan including:

• a shaft supported by bearing means for rotation about a vertical axis in a cabinet, said cabinet having a generally L-shaped front panel with a central opening therein;
• at least one shelf secured to said shaft for rotation therewith;
• door panels secured to said shelf and conforming to the opening in said L-shaped front panel;
• a rotational alignment mechanism for maintaining the shaft in a selected at-rest rotary position relative to said L-shaped front panel;
• said alignment mechanism including:
• a cam rotatable with the shaft and having a notch in a peripheral surface thereof;
• a follower including means selectively received in said notch for maintaining said shaft in the selected at-rest rotary position relative to said housing;
• the position of said follower being adjustable with respect to said housing;
• and
• means for adjusting the selected at-rest rotary position of said shaft relative to said housing;
• the improvement in said shaft-adjusting means which comprises:
• mounting means for pivotably mounting said follower to said housing for pivoting movement about an eccentric axis;
• wherein pivoting of said follower about said eccentric axis adjusts the angular position of the follower with respect to said housing, thereby changing the selected at-rest rotary position of said shaft relative to the housing.

In a lazy susan including a shelf structure rotatably mounted to a shaft supported by bearing means for rotation about a vertical axis in a cabinet, said cabinet having a generally L-shaped front panel with a central opening therein, door panels mounted to said shelf structure for rotation therewith, said doors panels being aligned within said central opening and about flush with said front panel when said shelf structure is in a closed position, and means for adjusting the vertical position of said shelf structure within said central opening relative to said cabinet;

• the improvement which comprises
• said means for adjusting the vertical position including
• wedge means disposed beneath said shaft for displacing said shaft along a vertical axis, said wedge means being mounted for displacement towards and away from said shaft;
• means on said shaft in sliding contact with said wedge means for transmitting movement of said wedge means to said shaft;
• and
• means for displacing said wedge means;
• wherein displacement of said wedge means causes said shaft to move along said vertical axis so as to align said door panels within said central opening of said cabinet front panel.
