  • Patent number: 5788057
    Abstract: An apparatus for the suspended storage of foodstuffs, particularly slabs of chocolate or the like, arranged on shelves (15) lying flat on trays (14) hanging from two parallel chains (12, 13) moving around a closed circuit that includes a supply run and a return run. Each tray (14) is combined with at least one shock absorbing device (61) for restricting the swinging motion thereof, quickly damping said motion and preventing the trays from bumping into one another. For this purpose, the shock absorbing device (61) comprises a braking disc located within a recess provided inside a housing and containing a viscous liquid.

  • Patent number: 5713455
    Abstract: An apparatus for the suspended storage of foodstuffs, particularly slabs of chocolate or the like, arranged on shelves (15) lying flat on trays (14) capable of accommodating a number of such shelves. The shelves (15) are releasable and arranged parallel to one another at a constant spacing, and each shelf forms a plate receiving at least one row of similar foodstuffs. The shelves comprise a closed profile member (80) and two end portions (82) that can be fitted onto the longitudinal ends of the member and are therefore reversible so that they can be reinserted in any position into the trays without using an indexing system.
