DETAILED DESCRIPTION OF EMBODIMENTS

(14) FIGS. 1a-1f illustrate a number of steps of a method for mounting a cover with a plurality of slidable lids 7 onto a refrigerated merchandising storage unit 1 according an embodiment of the invention.

(15) In FIG. 1a, it is illustrated how a spacer profile 5 is mounted onto the upward-facing edge of each of the two long sides 3 of a storage compartment 2 of a refrigerated merchandising storage unit 1. The spacer profiles 5 are arranged to be able to engage with the base profiles 11 (not shown in FIG. 1a) arranged at the ends of the two or more cover cassettes 6 (not shown in FIG. 1a) for fastening the cover cassettes 6 are fastened to the storage compartment 2. In the illustrated embodiment, the upward-facing edges of the two short sides 4 of the storage compartment 2 are curved. In other embodiments, they may be straight and horizontal just like the upward-facing edge of each of the two long sides 3.

(16) FIG. 1b illustrates how a first cover cassette 6 is mounted onto the storage compartment 2 at one end thereof. In the illustrated embodiment, the cover cassette 6 is assembled with two slidable lids 7 and a fixed lid 8 in a frame comprising two curved cross profiles 10 along the sides thereof and two base profiles 11 along the ends thereof. The fixed lid 8 is arranged on top of the cross profiles 10 at the centre of the cover cassette 6, whereas the two slidable lids 7 are arranged to be able to slide in an upper track 14 and a lower track 15, respectively, arranged along the inner side of each cross profile 10. Thus, by pushing or pulling the lid handle 9 arranged on a slidable lid 7, the slidable lid 7 can be slid away from or towards the edge of the storage compartment 2, respectively, moving under or over the other slidable lid 7 and under the fixed lid 8. In this way, access to the interior of the storage compartment 2 can be obtained and the opening can be closed again. In other embodiments, the cover cassette 6 can comprise other combinations of one or more slidable lids 7 and one or more fixed lids 8.

(17) By mounting two more such cover cassettes 6 like illustrated in FIGS. 1c and 1d, a full cover for the opening of the storage compartment 2 is obtained by means of the three cover cassettes 6 abutting one another. For each of the cover cassettes 6, the two base profiles 11 engage with the spacer profiles 5 mounted on the edges of the storage compartment 2, for instance through a click-together assembly.

(18) FIG. 1e illustrates how a cover profile 13 may be mounted along each long side 3 of the storage compartment 2 for covering the spacer profile 5 and the base profiles 11, thus forming a hand-rail along the edge of the storage compartment 2. The cover profile 13 may engage to the spacer profile 5 and/or the base profiles 11, for instance by a click-together assembly.

(19) Finally, FIG. 1f illustrates how a gap profile 12 may be mounted to seal the gap between the abutting cross-profiles 10 of two neighbouring cover cassettes 6 for obtaining a tight cover consisting of the three cover cassettes 6. These gap profiles 12 may, for instance, be mounted using double-sided adhesive tape 16 (see FIG. 2).

(20) FIG. 1g illustrates a refrigerated merchandising storage unit 1 obtained by performing the steps illustrated in FIGS. 1a-1f.

(21) FIG. 2 is a cross-sectional view of the assembly of two cross-profiles 10 of two neighbouring cover cassettes 6 of a refrigerated merchandising storage unit 1 according to an embodiment of the invention assembled as described above. Each of the two cross profiles comprises two longitudinal and generally U-shaped tracks 14, 15, each of which is arranged for receiving an edge of a slidable lid 7 in such a way that the slidable lid 7 can be slid along the longitudinal direction of the track 14, 15, the opposite edge of the slidable lid 7 being received by a corresponding track 14, 15 of the cross profile 10 on the other side of the cover cassette 6 (not shown in this figure). FIG. 2 further illustrates how the gap between the two cross profiles 10 can be sealed by a gap profile 12, which may, for instance, be fastened to the two cross profiles 10 by means of double-sided adhesive tape 16.

(22) FIG. 3a is a cross-sectional view of a spacer profile 5 according to an embodiment of the invention, comprising a number of interface features 18 for engagement with a base profile 11 (see FIG. 3d). Furthermore, in the illustrated embodiment, the spacer profile 5 is provided with a trimable wall 17, which can be cut for varying thicknesses of the side wall along the long side 3 of the storage compartment 2 (not shown in this figure). An appropriate cutting of this trimable wall 17 determines the correct positions of the base profiles 11 (not shown in this figure) relative to the storage compartment 2. FIG. 3a also illustrates how the spacer profile 5 may comprise a channel 19, for instance for a heater cable (not shown), at one end and a channel 20, for instance for a pin (not shown) for alignment of wall sections of the storage compartment 2 (not shown), at the other end. Typically, the spacer profiles 5 are glued onto the edge of the storage compartment 2 (and maybe secured with a few, small self-tapping screws, not shown) allowing for an instant positioning and mounting of the cover cassettes 6 onto the storage compartment 2 of the refrigerated merchandising storage unit 1.

(23) FIG. 3b is a cross-sectional view of a base profile 11 according to an embodiment of the invention, comprising a number of interface features 21 for engagement with a spacer profile 5 and a number of interface features 24 for engagement with a cover profile 13 (see FIG. 3d). Furthermore, in the illustrated embodiment, the base profile 11 comprises a couple of tracks 22 for bumper sealings 25 (see FIG. 3d) and a couple of channels 23, for instance for pins and screws (not shown).

(24) FIG. 3c is a cross-sectional view of a cover profile 13 according to an embodiment of the invention, comprising a couple of interface features 26 for engagement with a base profile 11 and a single interface feature 24 for engagement with a spacer profile 5 (see FIG. 3d).

(25) FIG. 3d is a cross-sectional view of a hand-rail assembly according to an embodiment to of the invention, comprising of a spacer profile 5, one or more base profiles 11 and a cover profile 13, which are clicked together using the interface features 18, 21, 24, 26, 27 designed therefore. The base profile(s) 11 may further be secured to the spacer profile 5 with a few, small self-tapping screws (not shown). A couple of bumper sealings 25 are arranged along the base profile 11 for softening the impact on the base profile 11, when a slidable lid 7 is closed by being drawn towards the base profile 7 until it bumps against it.

(26) It is particularly advantageous that a retainer arrangement is provided near said one or more U-shaped tracks 14, 15 and said one or more lid 7, 8 for retaining the lid in that track, wherein the retainer arrangement comprises a latch fixed to the lid and a protrusion 28 fixed to that track 14, 15, the latch and the protrusion 28 being arranged such that when lateral extraction forces are applied to the lid 7, 8 in a direction away from the track 14, 15, the latch and the protrusion 28 are forced into abutment producing a holding force so that a separation of the lid 7, 8 and the track 14, 15 is prevented, wherein either the protrusion 28 or the latch is made of a resilient flexible, material such that the edge of the lid 7, 8 can be inserted into the track 14, 15, by bending either the latch towards a surface of the lid or the protrusion 28 towards a side of the track 14, 15 on which it protrudes from. Such retainer arrangement is disclosed in international patent application WO 2018/069004 A1.
