Claims

1. Refrigerated display cabinet comprising a body, a movable section, and a closing mechanism, said closing mechanism connecting the movable section of the display cabinet with the body of the display cabinet for opening and closing said display cabinet, wherein said movable section has the same angular orientation through all positions of movement, wherein said movable section has a part projected over a product arrangement area having a horizontal section forming a shelf for supporting a product or collecting a payment thereof, wherein the part projected over the product arrangement area and the horizontal section are fully made of a transparent material, wherein said closing mechanism comprises independent frontal displacement means and independent horizontally lateral displacement means, and said independent frontal displacement means and said independent lateral displacement means are coupled to each other, said independent lateral displacement means includes a movement rail mounted to said movable section and a stationary rail on which the movement rail travels linearly on, wherein said independent frontal displacement means includes a pair of outer telescopic elements that are each mounted to a shelf in the body of the display cabinet and a pair of inner telescopic elements that each travel linearly in a respective outer telescopic element, an outer end of each of the inner telescopic elements is mounted to a respective end of the stationary rail, wherein the frontal displacement means causes the movable section to move along a perpendicular axis that is in a perpendicular direction with respect to the front surface of the cabinet and the horizontally lateral displacement means causes the movable section to move along a lateral axis that is in a horizontal parallel direction with respect to the front surface of the cabinet, and wherein the independent horizontally lateral displacement means can be opened and can move towards either side.

2. Refrigerated display cabinet according to claim 1, wherein the independent frontal displacement means comprise linear bearings.

3. Refrigerated display cabinet according to claim 1, wherein the inner and outer telescopic elements slide relative to each other.

4. Refrigerated display cabinet according to claim 1, wherein the movement rail and stationary slide relative to each other.

5. Refrigerated display cabinet according to claim 1, comprising travel stops for limiting the travel of the independent lateral displacement means and independent frontal displacement means.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

(9) The closing mechanism (1) for refrigerated display cabinets (2) of the invention is configured in a display cabinet (2) of the type implementing a movable closing section (3), said mechanism (1) being: disposed relating said movable section (3) with the body (4) of the display cabinet (2) to open and close it, as shown in FIGS. 3 to 8, said movable section (3) having a part projected (8) over the product display area (9) fully or partially made of transparent material. The figures show how this projected part (8) has horizontal sections (8a) that configure a kind of shelf on which to place the product or make payments in the commercial transaction.

(10) In accordance with the invention, the mechanism (1) comprises independent frontal displacement means and independent lateral displacement means on either side indifferently for the movable section (3). This makes it possible to open said movable section (3) as shown in the sequences configured by FIGS. 1, 3 and 5 and/or 1, 3 and 7, without the upper horizontal section (8a) interfering laterally with similar sections of the other identical display cabinets (2a) located on one or both sides of the display cabinet (2) considered. It also allows aperture towards both sides, facilitating the tasks to be performed with the movable section (3) open.

(11) In the non-limiting example shown in the figures, the frontal displacement means are supported by the body (4) of the display cabinet (2) (see FIG. 3, 5 or 7) and comprise linear bearings (6), although they could complementarily or alternatively comprise other equivalent elements belonging to the state of the art, such as frontally sliding elements, telescopic elements, etc., not shown. As regards the lateral displacement means, in this non-limiting example they comprise laterally sliding elements (5) (see FIG. 4, 6 or 8), Also, in general, the lateral displacement means may be disposed coupled to the frontal displacement means, maintaining the independence of their movements. For example, in the figures it can be observed how the laterally sliding elements (5) are coupled to the end of the linear bearings (6).

(12) If the movable section (3) is very heavy, the installation of rolling supports, not shown, has additionally been envisaged, such as directionally rotating wheels that can be implemented directly on the movable section (3) and/or on the lateral displacement means and/or on the frontal displacement means.

(13) Lastly, the installation of travel stops (7) for limiting the travel of the independent lateral displacement means and/or the independent frontal displacement means has been envisaged. The figures show the travel stops (7) for limiting the travel of the independent lateral displacement means.

(14) Having sufficiently described the nature of the invention and the manner in which to put it into practice, it is hereby stated that the indications mentioned above and represented in the attached drawings are susceptible to changes in detail, provided that they do not alter the basic principle.
