A lazy susan (24) including a shaft (30) supported for rotation about a vertical axis within an L-shaped cabinet (10) is provided with a rotary catch mechanism (40) which maintains the shaft at a selected rotary position relative to the cabinet (10). The catch mechanism (40) includes a cam (44) and follower (42) which maintain the shaft (30) in the selected rotary position. The follower (42) is provided with means for adjusting its angular position so as to change the orientation of the follower (42) with respect to the cabinet (10) and thus adjust the position of the shaft (30) and attached door (22a-b) relative to the cabinet (10). The follower (42) is adjusted by an eccentric (70) mounted for rotation with the follower (42) so that upon rotation of the eccentric (70), the follower (42) is likewise rotated to change its position relative to the cabinet (10). The vertical position of the lazy susan (24) within the cabinet (10) can also be adjusted with a shaft height adjustment mechanism (80) which includes a wedge (82) disposed beneath the shaft (30). The wedge (82) displaces the shaft (30) vertically along its axis upon movement of the wedge (82) either toward or away from the shaft (30).

In a rotary catch mechanism for a shaft supported in a housing by bearings for rotation about a vertical axis, said mechanism including: a cam having a notch in a peripheral surface thereof and mounted for rotation with said shaft; a follower including means selectively received in said notch for maintaining said shaft in a 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.
