Patent attributes
A refrigerated merchandising storage unit for display and sale of foodstuff or the like is disclosed including a storage compartment having an essentially rectangular top opening, the storage unit further includes a cover including a plurality of lids for being arranged displaceably for opening the storage unit and a rail system with two or more mounted rails arranged between two opposite sides of the opening. Each rail includes a number of elongated and generally U-shaped tracks wherein each of the lids are arranged to be mounted between a first and a second rail adjacent to one another. The first rail includes a first track and the second rail includes a second track, and the rails are arranged such that the lid can be mounted by displacing an edge of the lid inside the first track until the opposite edge of the lid can be inserted inside the second track. The storage unit further includes a retainer arrangement provided near the first track or the second track and the lid for retaining the lid in that track. The retainer arrangement includes a latch fixed to the lid and a protrusion fixed to that track, the latch and the protrusion being arranged such that when lateral extraction forces are applied to the lid in a direction away from the track, the latch and the protrusion are forced into abutment producing a holding force so that a separation of the lid and the track is prevented.
