Description

The invention relates to a horizontal refrigerated showcase where the products within said showcase are advantageously displayed, the visibility of said products being maximal.
Horizontal refrigerated showcases (that are, in essence, containers provided with an opening/closing system, as well as with a system for refrigerating the interior of the container) are used in commerce for the storage and the display of perishable products available for sale. Clients passing by the showcase look at the displayed products and can reach them by means of the opening/closing system, in order to pick the preferred products that they wish to buy.
Besides products quality, of utmost importance is the degree of visibility of the products within the showcase, which has a positive impact on the buying process impetus.
The market demand is for refrigerated showcases offering as much exposure as possible for the products displayed within the showcase.
Prior art comprises horizontal refrigerated showcases approaching this problem by providing the refrigerated showcase with transparent lateral walls as well as with an opening/closing system made of a transparent material.
The disadvantage of prior art showcases is that some components (namely the sliding paths for the cover, the frames of the panes, and the sliding seals) are opaque, reason why a client, looking from certain distances and from certain unfavourable angles, has a part of the showcase content obturated by said opaque components.
Another disadvantage of prior art showcases is that they have a relatively complicated structure, wherein said sliding paths are separate components attached to the showcase walls.
A prior art horizontal refrigerated showcase embodiment is schematically shown, in a simplified manner, in Figure 1. By simplified manner is meant that the showcase is not shown entirely, but only a detail, in cross sectional view, of an upper zone neighbouring the sliding paths.
The prior art refrigerated showcase has a substantial parallelepipedic shape, meaning that it has a base, four lateral walls substantially perpendicular to the base and an opening/closing system arranged at the top.
Each lateral wall consists of two transparent parallel panels P1, P2 of the same height and kept apart from each other by means of at least one spacer D.
Between two opposed lateral walls, two transparent panes G1, G2 are arranged in parallel planes, with the possibility to slide on sliding paths C12, C23 that are fixed along each of said two opposed lateral walls. The sliding of the panes G1, G2 on the sliding paths C12, C23 is made by means of sliding seals S1, S2 that are fixed to frames F1, F2.
The sliding paths C12, C23, the spacer D, the frames F1, F2 and the sliding seals S1, S2 are made of non-transparent materials, fact that is a disadvantage because an observer/client looking at the showcase from the direction marked with arrow A, will have the image of the products within the showcase blocked by the aforementioned non-transparent parts, such that a zone within the showcase (and implicitly some of the displayed products) will remain concealed from the sight of the observer/client.
DE20203716U U1 discloses a refrigerated showcase having sliding doors supported on tracks.
The present invention aims to eliminate the afore-mentioned disadvantage, by providing a horizontal refrigerated showcase comprising:

a base wall;
four transparent lateral walls, each fixed substantially perpendicular to the base wall, such that the showcase has a substantially parallelepipedic shape;
an opening/closing system of the showcase, arranged opposed in respect to the base wall,
wherein the opening/closing system comprises a plurality of transparent panes, arranged in parallel planes, each pane having a substantially rectangular shape,
- each pane resting on two of its opposed sides, alog the entire length of said sides, on a respective sliding path,
- each pane being capable to move in its own plane, on the respective sliding paths, in a direction that is the same with the direction of the sides resting on the sliding paths,
- wherein the sliding paths are attached respectively to two opposed lateral walls of the showcase, walls that are parallel to the panes moving direction,
each transparent lateral wall corresponding to the sliding paths consists of transparent parallel panels having ascending heights starting with the innermost panel and ending with the outermost panel,
the transparent panels being kept appart from each other by means of transparent spacers arranged such that the upper surface of each spacer serves as a sliding path for a respective pane.

In a preferred embodiment, each pane may rest on the associated sliding paths by means of transparent frames fixed to the entire length of the sides of the pane that are parallel to the moving direction.
In a preferred embodiment, each pane may rest on the associated sliding paths by means of transparent or semi-transparent sliding seals fixed to the entire length of the sides of the pane that are parallel to the moving direction.
In a preferred embodiment, each pane may rest on the associated sliding paths by means of transparent or semi-transparent sliding seals fixed to associated transparent frames fixed to the entire length of the sides of the pane that are parallel to the moving direction.
In a preferred embodiment, each spacer may be made of a wear-resistent transparent material.
In a preferred embodiment, the upper surface of each spacer may be coated with a wear-resistent transparent material by means of a transparet adhesive.
In a preferred embodiment, the surface portion of a panel that surpasses in height the precedent panel and that is oriented towards the associated pane, may be coated with a layer of wear-resistent transparent material by means of a transparent adhesive.
Any of the above mentioned preferred embodiments have the advantage that from whatever direction an observer/client is looking, absolutely all the interior of the showcase remains visible.
Another advantage of the invention is that said sliding paths are an integral part of the associated lateral walls of the showcase, fact that simplifies the showcase manufacturing process. Unlike the invention, in the case of prior art showcase from Figure 1, the sliding paths are a separate part attached to the associated wall of the showcase.
The invention will be better understood from the following embodiments, explained in detail and based on the figures, that represent:

Figure 1 : detail, in section view, of an upper zone of a prior art refrigerated showcase;
Figure 2: details, in section view, of an upper zone and of a lower zone of a refrigerated showcase according to the invention;
Figure 3 : detail of the upper zone of Figure 2, in axonometric view.

Figure 1 was previously explained in the chapter of prior art presentation.
An embodiment according to the invention is shown in Figures 2 and 3, comprising:

a base wall B;
one of the four transparent latelal walls of the showcase; although not shown in Figures 2 and 3, all four transparent lateral walls are fixed substantially perpendicular to the base wall B, such that the showcase has a substantially parallelepipedic shape;
an opening/closing system of the showcase, arranged opposed in respect to the base wall B,
wherein the opening/closing system comprises two transparent panes G1, G2 arranged in parallel planes, each pane G1, G2, having a substantially rectangular shape,
- each pane G1, G2 having two opposed sides on which are fixed, along the entire length of said sides, a respective transparent frame F1, F2; to each transparent frame F1, F2 is mounted a respective transparent sliding seal S1, S2 respectively in contact with an associated sliding path C12, C23,
- each pane G1, G2 being capable to move in its own plane, on the respective sliding paths C12, C23, in a direction X that is the same with the direction of the sides of the panes G1, G2 that are provided with frames and sliding seals,
- wherein the sliding paths C12, C23 are attached to two opposed lateral walls respectively, walls that are parallel to the moving direction X,
each transparent lateral wall corresponding to the sliding paths C12, C23 consists of three transparent parallel panels P1, P2, P3 having ascending heights starting with the innermost panel P1 and ending with the outermost panel P3,
the transparent panels P1, P2, P3 being kept appart from each another by means of transparent spacers D12, D23 arranged such that the upper surface of each spacer D12, D23 serves as a sliding path C12, C23 for a respective pane G1, G2.

For clarity reasons (to avoid the excessive loading of the drawing), in Figure 3 are present only some of the references of Figure 2.
Another advantage of the showcase according to the invention is that the cooling of the showcase is more efficient due to the thermal barriers consisting of the air-filled gaps between the panels P1, P2, P3 of the lateral walls.
The embodiment of Figures 2 and 3 is not a limiting one, i.e. the refrigerated showcase according to the invention may have lateral walls comprising a different number of transparent panels and the opening/closing system may have a different number of transparent panes.
In addition, the shapes of the sliding seals and of the frames are non-limiting, said parts may have any other shape that is suitable to alow them to perform their function.
According to Figure 2, the upper surface of each spacer D12, D23 is coated with a layewr of wear-resistent transparent material 1 by means of a transparent adhesive 2.
The surface portion of a panel P2, P3 that surpasses in height the precedent panel P1, P2 and that is oriented towards the associated pane G1, G2, is coated with a layer of wear-resistent transparent material 1 by means of a transparent adhesive 2. Non-limiting examples of wear-resistent transparent materials 1 may be: PVC, PC, PMMA, ABS, PBT, TPU, etc.
Non-limiting examples of transparent adhesives 2 may be: adhesive strip, monocomponent or bicoponent silicone, etc.
Starting from the embodiment of Figure 2, one can obtain other embodiments of the invention, such as in the following examples i - iii, in which:

i) the sliding seals S1, S2 are missing, and each pane G1, G2 is resting on the associated sliding paths C12, C23 by means of the transparent frames F1, F2 (that will have a suitable geometry, different from that of Figure 2);
ii) the transparent frames F1, F2 are missing, and each pane G1, G2 is resting on the associated sliding paths C12, C23 by means of the transparent sliding seals S1, S2 (that will have a suitable geometry, different from that of Figure 2) fixed directly on the panes G1, G2;
iii) the sliding seals S1, S2 as well as the transparent frames F1, F2 are missing, and the panes G1, G2 are sliding directly on the sliding paths C12, C23 (that will have a suitable geometry, different from that of Figure 2).

In any of the embodiments i, ii, iii or that from Figure 2, the layer of wear-resistent transparent material 1 together with the adhesive 2 may be missing, case in which each spacer D12, D23 is made of a wear-resistent transparent material and the upper surface of each spacer D12, D23 serves as an associated sliding path C12, C23.
