  • 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.

  • Patent number: 4648517
    Abstract: A shelf support structure with upright posts of sheet metal sections and horizontal braces of sheet metal sections, connecting these with each other, provides with a simple structure an inherently stable connection between the posts and the horizontal braces. The sheet metal sections of the posts have an aperture at one longitudinal side and are symmetrical in cross-section with respect to a plane crossing this aperture. The aperture is terminated on both sides by flanges protruding outwardly at right angles from the walls adjoining it and a longitudinal ledge protruding into the post is located opposite the aperture, symmetrically to the plane crossing the aperture. The horizontal braces engage with their ends into the sheet metal sections forming the posts up to the wall lying opposite the aperture and are there equipped with an indentation in whose area they embrace the longitudinal ledge in the posts in a fork-like manner.

  • Patent number: 4561705
    Abstract: A storage and transport container comprises a pair of like housings each having a normally vertical back wall having upright and parallel side edges and horizontal top and bottom edges, a pair of generally parallel side walls extending horizontally in one direction from the side edges, and respective generally parallel top and bottom walls bridging the side walls and extending in one direction from the top and bottom edges. Thus the housing has a front side open in the one direction. At least one horizontally extending partition projects in the one direction from the back wall intermediate the top and bottom walls, bridges the side walls, and forms two housing compartments. The top, side, and bottom walls each have a rear edge attached to the respective edge of the back wall and a front edge spaced in the one direction therefrom. A loop formed generally at the front edge of the top wall and extending upwardly therefrom is generally centered between the side walls.

  • Patent number: 4501456
    Abstract: A rack designed to accommodate several tiers of drawers has a frame spanned by one or more shelves defining a plurality of storage levels each partitioned by at least one upright divider into a plurality of compartments disposed side by side, each compartment having a wide-open front end and a rear end which may be partly obstructed by a low sill allowing an inserted drawer to be rearwardly extracted on being lifted above that sill. A profiled web in an upper zone of the front end of each compartment, projecting from above with a height slightly exceeding that of the sill, coacts with an upper rear flange of the respective drawer to prevent its forward extraction by a sliding motion through enabling such extraction by an upward tilting of the drawer; that web also lets the drawer hang out of its compartment with a slight downward tilt in a forward position. The top of the frame is concave to serve as an open ancillary receptacle.
