Abstract
A rotary fitting for a cabinet with top and bottom walls comprises a rotating supporting column, a top and a bottom rotary mounts for the supporting column, and at least one shelf to be fixed to the supporting column. The supporting column has a main tube, a bottom element mounted to the main tube, and a height adjustment device for a height of the main tube above the bottom rotary mount. The height adjustment device comprises a screw and a nut screwed onto the screw. One of the screw and the nut is fixed to the bottom element, and the other is axially supported within the main tube and has a bevel gear. There is a guiding hole in the main tube adjacent to the bevel gear, through which the bevel gear can be engaged and rotated by a screwdriver crosstip.

A rotary fitting for a cabinet having a body including a top wall and a bottom wall, the rotary fitting comprising:
- a rotating supporting column having a longitudinal axis, a main tube extending along the longitudinal axis, a top end, a bottom element mounted to the main tube for rotation with the main tube about the longitudinal axis and having a bottom end, and a height adjustment device configured for adjusting a height of the main tube above the bottom end along the longitudinal axis,
- a top rotary mount configured for being fixed to the top wall and for laterally and upwardly supporting the top end of the rotating supporting column in a rotating way,
- a bottom rotary mount configured for being fixed to the bottom wall and for laterally and downwardly supporting the bottom end of the bottom element of the rotating supporting column in a rotating way, and
- at least one shelf configured for being fixed to the main tube for rotation with the rotating supporting column about the longitudinal axis,
- wherein the height adjustment device comprises a screw and a nut screwed onto the screw, wherein one of the screw and the nut is fixed to the bottom element and wherein the other of the screw and the nut is axially supported along the longitudinal axis within the main tube and has a bevel gear,
- wherein a guiding hole in the main tube is located adjacent to the bevel gear such that the bevel gear can be engaged and rotated about the longitudinal axis by a screwdriver crosstip inserted into the guiding hole;
- and
- wherein a guiding wheel is arranged at a fixed axial distance to the bevel gear, wherein a beveled rim of the guiding wheel is facing the bevel gear.
