NOVELTY - The organic waste composter (1) includes stable framework, wire mesh-like lateral parts, single- or multi-piece stable cover and two-piece plate-like base flaps (4), which are operable via mechanics and is attached at the framework (2). A pivot bearing is attached in the area of the lower framework rotation or in the area of the side beam. A single piece locking bar (8) is attached in the pivot bearing, closes or releases the base side of the base flap, supports an actuating grip at the upper end and is connected in the hand area via the actuating grip.    USE - For composting organic wastes in the garden.    ADVANTAGE - The composter is more economical and has high composting capacity of the organic wastes as well as the grating box of the composter ensures good ventilation and prevents the accumulation of wetness.    DETAILED DESCRIPTION - The organic waste composter (1) includes stable framework, wire mesh-like lateral parts, single- or multi-piece stable cover and two-piece plate-like base flaps (4), which are operable via mechanics and is attached at the framework (2). A pivot bearing is attached in the area of the lower framework rotation or in the area of the side beam. A single piece locking bar (8) is attached in the pivot bearing, closes or releases the base side of the base flap, supports an actuating grip at the upper end and is connected in the hand area via the actuating grip. The mechanics are disposed via two oppositely facing pivot bearing in the area of the lower framework or in the lower area of two adjoining side beam. The actuating grip is connected above the upper framework rotation or outside of the composter in the upper area of the vertical cross-beams. Both base flaps are attached at opposite sides of the lower framework rotation. The locking bar has locking bolts that are fastened to the free end of the base flaps. The locking bar forms a unilateral- or bilateral handle for closing the flaps. A flap part of the base flaps is directly lockable by the locking bar and other flap part is indirectly closed by the first flaps part as a result of overlap. The two-piece base flap carries the locking bolt at the free end. The base flaps carry a wire mesh insert. Feet or wheels are secured in the area of the lower framework rotation and staples (3) are secured in the upper framework rotation, which carries the stable cover. The cover is attached at the upper framework circulation and exhibits a support bar, which is attached in the cover or the upper framework rotation. The framework size for a garden execution lies 0.5-5 m3. The locking bolt is slidable in the area of the lower framework rotation by recesses, eyelets or sockets and secures the base flaps against unlocking. The framework and the base flaps from galvanized angle iron are welded, to which a mesh-like wire or expanded metal mesh is interior-laterally patterned.
