  • Patent number: 5551594
    Abstract: A box-shaped container of plastics material, particularly a storage and transport container includes a bottom with a flat upper side and a bottom side which is stabilized by stiffening ribs. Flat webs extending in a plane parallel to the plane of the bottom extend along the rim of the bottom. The flat webs form in the manner of a frame a center field of the bottom. The stiffening ribs in the center field intersect each other in the manner of a grid. The flat webs form support surfaces of the container and rest spaced apart from the plane of the bottom on stiffening ribs arranged transversely of the rim of the bottom. Pocket-shaped free spaces are formed between the bottom side of the container bottom, the upper sides of the flat webs and the transversely extending stiffening ribs, wherein the free spaces are completely open to the side of the rim of the bottom.

  • Patent number: 5401915
    Abstract: An identification unit for garbage cans is proposed, which can be emptied by means of emptying devices or dumping into collection vehicles as well as being able to be weighed for determination of the weight of the garbage contained therein on the emptying device before and after the emptying process, wherein the garbage can carries a coding sensor, which can be made to communicate with an identification system on board of the collection vehicle assigned to the emptying device.Since a lasting operationally secure layout of the identification unit is important, the coding sensor is housed in the receptacle in the stiffening collar or dumping engagement grip 6 at the garbage can and/or is enclosed on all sides.

  • Patent number: 5397022
    Abstract: A box-shaped container of plastics material, particularly a storage and transport container. The container includes a bottom which has a plane upper side and an underside which is stabilized by means of stiffening ribs. Flat webs extend along a bottom edge of the container in direction of the plane of the bottom. The flat webs are supported at a distance underneath the bottom plane by means of additional stiffening ribs which extend transversely of the bottom edge. The flat webs form the bottom surface of the container. Pocket-like free spaces are defined between the underside of the bottom, the upper sides of the flat webs and the transversely directed stiffening ribs. The free spaces are completely open at the bottom edge. The inwardly directed border edges of the flat webs are spaced at a distance from the stiffening ribs on the underside of the bottom which extend parallel to the inner edges, so that downwardly open passages are defined in the pocket-like free spaces at the inwardly directed border edges.

  • Patent number: 5332115
    Abstract: A box-shaped container is described which comprises flat straps spaced beneath the base of the container. These flat straps extend along the base edge and are abutted against the base by stiffening ribs. The base structure contains pocket-like free spaces formed by the base bottom side, the flat strap top side and the stiffening ribs oriented transversely thereto, which free-spaces are open on the sides of the base edge. A bend-through of the container base is to be securely countered by simple means if high weighted commodities are loaded into the container. Stiffening ribs comprise passages in the region of the individual pocket-like free spaces, which are followed by channels which open towards the bottom. Neck-like molded knobs are provided in the channels at the bottom side of the container base. Stiffening sections can be slid into the channels and fastened to the knobs.

  • Patent number: 5326939
    Abstract: The proposal is for an identification unit for rubbish containers (1) which can be emptied by emptying devices or by tipping into dustcarts and can be weighted to determine the weight of the rubbish in them before and after emptying on the emptying device or tipping. The rubbish container (1) has a recognition sensor (7) which can be brought into correspondence with an identification system on board the individual dustcart and associated with the emptying device or tipping out procedure. To give the identification device long-term reliability, the recognition sensor (7) is inserted and/or enclosed on all sides in a recess (8) of the stiffening lip or tipping grip (6) on the rubbish container (2).

  • Patent number: 5040469
    Abstract: A shelf system includes at least four posts and shelf members suspended from hooks which are arranged in rows and are cut out from the sides of the posts and are bent into the interior of the shelf system. Above the hooks but within the structural height of the shelf members, projections are formed in the sides of the posts for filling out the gaps between the edges at the ends of the shelf members and the sides of the post. Tongues are provided above the projections. The lower ends of the tongues are in alignment with the upper surfaces of the shelf members. When the tongues are bent upwardly, they secure the shelf members against being lifted out.

  • Patent number: 4848578
    Abstract: A storage and/or transport container of plastics material with a rectangular bottom and longitudinal and transverse side walls extending upwardly from the rectangular bottom. The upper edges of the side walls define a rectangular opening having a size greater than the rectangular bottom. Two support members are hinged to the container adjacent the upper edges of the transverse side walls. The support members can be swung from a first position in which they leave the rectangular opening clear to the transverse side walls into a second position in which they are located in the rectangular opening adjacent the transverse side walls so as to partially bridge the openings. In the second position, the distance between the sides of the support members facing each other is smaller than the width of the container bottom the two transverse side walls. The ends of the support members have support walls which extend transversely of the longitudinal direction of the support members.
