Abstract: A composter having a downwardly open container (1) which stands on the ground (2) and has a filling opening which is arranged on the top side and can be closed by a lid (9). An unventilated upper chamber (10), which is arranged beneath the filling opening, opens laterally into a ventilated vertical shaft (13) which extends downward in the container (1) and is bounded at the lower end by a horizontally arranged lower plate (14) which is arranged between the shaft (13) and a downwardly open, ventilated lower chamber (17) which reaches down as far as the lower end of the container (1), and next to which in the container casing there is arranged a closable lateral removal opening. The lower plate (14) can be pivoted about a horizontal pivot (15) and is coupled to a movement mechanism which is to be actuated by hand and has a handle (18) arranged on the outside of the container (1).

Abstract: A cold frame is formed with lateral wall elements containing transparent hollow chamber panels, and supports which are provided with lateral flanges. The lateral wall elements include lateral edge areas provided with through-passages and formed by the hollow chamber panels thereof, and rest against the flanges of the supports. The lateral wall elements are connected to the supports by clamping devices. The clamping devices include clamping elements which rest against the inner sides of the hollow cavity panels forming the edge areas of the lateral wall elements and are clamped between the hollow cavity panels and the tops of positioning bars belonging to the clamping devices. The bars protrude from the through-passages of the hollow chamber panels and they are rigidly connected to the flanges of the supports.

Abstract: An umbrella-like laundry dryer includes a central upright tube and a clothes-line-carrying framework, which can be unfolded by an actuating device and has supporting arms connected movably to an upper end section of the upright tube and clothes-line carrying arms connected for articulation to lower ends of the supporting arms and linked to a lower sleeve to be displaced along the upright tube. The actuating device has a hoisting line anchored to the upper end section of the upright tube, running downward parallel to the upright tube and deflected away at the lower sleeve from the upright tube. The hoisting line is coupled to an opening lever linked to a clothes-line carrying arm above the lower sleeve for pivoting from a downwardly pointing, lower position into an upwardly pointing, upper position, to unfold the carrying framework.

Abstract: An umbrella-type laundry drying apparatus has a central upright tube carrying a spreading framework, which can be swung open via an actuating mechanism. A tubular protective sheath can be pulled over the collapsed framework and clothesline. The open-out framework has carrying arms for the clothesline, which are arranged in the form of rays of a star and are articulated on a lower sliding sleeve, and supporting arms, which are connected in an articulated manner to the carrying arms and are articulated on a upper sliding sleeve. At least the lower sliding sleeve can be displaced along the upright tube and secured in different positions on the upright tube. The actuating mechanism for spreading the framework is formed by two of the carrying arms each bearing a handle which, with the open-out framework collapsed, is covered by the protective sheath when it is pulled over the collapsed framework.

Abstract: An umbrella-type laundry drying apparatus has a central upright tube which carries a spreading framework for the laundry line. The framework is folded open via a hoisting line. The spreading framework has an upper sleeve which surrounds the upright tube and on which supporting arms arranged in the form of a star are articulated. These arms are articulated at their lower ends to the carrying arms for the laundry line. The carrying arms are articulated with their lower ends on a lower sliding sleeve that surrounds the upright tube, can be fixed in various positions on the upright tube, and is equipped with a force transmission actuable via a tension line. The force transmission has a force step-up and a force transmission element coupled to the tension line. When the tension line is actuated, it generates an upwardly directed movement step of the lower sleeve.

Abstract: An umbrella-type clothes drier can be covered with a protective cover when it is not in use. An unfolding and folding spreading frame that supports a clothesline is preferably disposed in an adjustable manner on the central upright tube of the apparatus. The protective cover can be pulled over the folded spreading frame and the clothesline from the upright tube and can be retracted into the upright tube at the inner end section thereof, which remains inside the upright pipe. The outer end section of the protective cover supports a cap which overlaps the upper end of the upright tube when the protective cover is retracted into the upright tube.

Abstract: A clothes drier has lifting device that can be fastened to a ceiling and that can be operated in stepwise fashion. The lifting device supports a drier frame carrying the clothes line. The lifting device is received in a downwardly open profiled box, which can be fastened to the ceiling, and acts on the central longitudinal support of the drier frame, which can be folded together to form a long bar and in the folded-together state can be received in the profiled box. The frame has part-frames arranged on both sides of its longitudinal support, which can be folded together toward the longitudinal support and in the process in each case enclose the clothes line carried by them.

Abstract: An extruded polycarbonate highly transparent plate having outer layers bridged by ribs to define compartments in the plate running to opposite edges thereof, is formed with a frame by injection molding the frame onto the edges of the plate which have been squeezed closed in the injection mold. The frame plastic, e.g. glass fiber reinforced polystyrene has a melting point less than that of the transparent plate.

Abstract: In an apparatus for making compost, which apparatus comprises a preferably upwardly tapering container (1), which is adapted to be vented at its top and has an upper charging opening (4), which can preferably be closed by a cover (3) and which serves to receive the material to be composted, also a lower discharge opening (7), which can preferably be closed by a flap (6) and which permits the compost to be taken out, a plurality of lower ventilating openings (9), which extend through the container wall (5), and a plurality of air-guiding elements (10), which are provided on the inside surface of the container wall (5) and serve to guide the supply air, which enters through the ventilating openings (9) and flows along the inside surface of the container wall (5). The air guiding elements (10, 12, 13, 15) on the inside surface of the container wall (5) define a flow passage labyrinth, which the air flow along the container wall (5).
