(57) A rotatable grid, particularly for a domestic cooking range comprising an oven cavity
and at least one conventional planar grid shelf supported by guides affixed to the
lateral walls of the oven cavity comprises a disk-shaped grid and a support ring located
therebelow in a concentric arrangement and connected thereto for rotation about a
vertical axle. Upper and lower end portions of the axle are received in a freely rotatable
fit in a hub member of the disk-shaped grid and a bearing support member removably
secured to the planar grid shelf, a disk of a low-friction material being preferably
interposed between the hub member and the bearing support member. The rotatable grid
does not require any modification of the conventional design of the oven cavity and
is adapted to be readily dismounted from the bearing support member for use of the
grid shelf and facilitating cleaning of the oven cavity and its accessories.
