Description

FIELD OF THE INVENTION

The present description relates to demonstration booths with maintained thermal conditions with one or more open demonstration sides. This description has been developed, in particular, with particular attention to the demonstration structures for the said demonstration stands.

Description of the prior art

Demonstration structures for demonstration booths with maintained thermal conditions with open demonstration sides are known in the technical field, that is, those in which, on the sides of the demonstration stand, there are sections through which the presented products are visible and accessible from the outside.

Possible embodiments comprise demonstration shelves mounted one above the other and a support column for said shelves, which forms a path for air flow and has a set of outlets for outputting air flow over the shelves. The air stream that reaches the top of the column is deflected in accordance with the downward flow that flows in front of the shelves so that it forms an air film covering the open demonstration sides.

A solution of this kind, for example, is described in document No. FR-A-2794956.

Demonstration stands of this type, as described above, have various disadvantages.

First of all, unless the fans are also installed in the upper part of the demonstration structure, the air film obtained in the said demonstration stands is mainly effective only for the upper shelves, while it has a relatively weak effect for other shelves. In addition, regardless of the presence or operation of fans specifically designed to generate an air film, said air film itself represents limits to its effectiveness both in terms of its closing effect and in its effect on cooling the shelves.

In addition, demonstration stands of this type, as described above, are relatively bulky, since around all open demonstration surfaces they must have sufficient space for air to pass through.

Mentioned demonstration stands, therefore, are not well suited for use in temporary installation locations, which require convenient designs that are easy to transport.

Document No. DE 20303061U1 describes a display stand in which a plurality of air flows are provided on each shelf, which cover the display sides with air.

However, the solution proposed in said document is extremely complex. In the said solution, a central column is actually provided, through which air is passed to various shelves and radially from which there are many channels designed to form various flows over individual shelves. The said channels are formed by walls that delimit the shelves, leaving a very limited space for the latter. In addition, in the aforementioned solution, the cooling element is installed along the column through which air is passed to the shelves, which significantly complicates the design of the demonstration structure itself and constantly limits the use of the latter together with the cooling system with which it is connected.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a design that does not present the disadvantages mentioned above.

In accordance with the invention, the aforementioned task is achieved due to the demonstration design having the characteristics presented in the following claims.

The claims form a single part of the technical description presented here in relation to the invention.

In various embodiments, said display design may include a first column forming a first air flow path. The first column may have a sequence of first openings for supplying air flow to the shelves, and through the first openings, air enters in the first supply direction. The demonstration structure may further comprise at least one second column forming a second air flow path following and in the opposite direction with respect to said first path. The second column may have a sequence of second openings for supplying air flow over the shelves, through said second openings, air is supplied in a second supply direction that is not parallel to said first direction.

In various embodiments, the demonstration design may be structurally very simple and at the same time may be configured to provide effective cooling effect on various shelves. As, in addition, it will be more clear from the following description, in various embodiments, the demonstration design described here can be simple and quick to install.

In various embodiments, the demonstration structure described herein can be easily detached from the thermodynamic assembly with which it is connected, so that it can preferably be designed for various interchangeable thermodynamic assemblies.

In various embodiments, due to its simplicity, the demonstration structure may also preferably be made of cardboard.

DETAILED DESCRIPTION OF THE INVENTION

The following description illustrates various specific details aimed at a thorough understanding of the embodiments. These embodiments may be presented without one or more specific details, or using other methods, components or materials, etc. In other instances, well-known structures, materials, or operations are not illustrated or described in detail so that various aspects of the embodiments are not obscured.

A reference to an “embodiment” or “one embodiment” within the scope of this description means that the specific configuration, construction, or characteristic disclosed in relation to the embodiments is contained in at least one embodiment. Therefore, phrases such as “in an embodiment” or “in one embodiment” that may be present at various places in this description do not necessarily refer to the same embodiment. In addition, specific devices, structural forms, or characteristics may be combined in any suitable manner in one or more embodiments.

The links provided here are used for convenience only, and therefore do not define the scope or scope of the embodiments.

1, reference numeral 1 denotes a display stand with many open display sides. In various embodiments, the demonstration stand 1 is, in particular, a stand with thermal conditions and for this purpose has a thermodynamic unit 2 having an air treatment function that conditiones the demonstration stand.

In various embodiments, the use of such a display stand relates to the demonstration of products that are required to be kept cold, that is, to be kept at a temperature lower than room temperature. For the aforementioned application, the thermodynamic assembly 2 has a conventional type cooling system for cooling air, providing a condition that includes, for example, a compressor, a condenser, a flow separation valve and an evaporator.

In the case of an application in which, instead, it is required to demonstrate products that need to be kept warm at a temperature higher than room temperature, the thermodynamic assembly 2 may be, as an alternative or in addition to a cooling system, a heating system equipped with for example, electric resistors for heating air conditioning.

In both cases, the thermodynamic assembly 2 further comprises a fan of any conventional type for movement of conditioned air.

The structural details of the thermodynamic assembly 2, however, will not be described here in more detail, since they themselves do not play a decisive role.

In various embodiments, the demonstration stand 1 comprises a demonstration structure 3, which includes a vertical row of demonstration shelves 4 mounted on top of each other, a first column 5 passing through said row of shelves, which has a sequence (plural) of first outlets 5 ′ for flow air conditioning. In various embodiments, the demonstration structure 3 has at least one second column 6 having a sequence of second outlets 6 'for supplying a stream of conditioned air to each of the shelves 4. In addition, the first column 5 and the second column 6 are in fluid communication with the other in such a way that they determine the consecutive paths of the flow of conditioned air along the rows of shelves 4, which have directions opposite to each other.

In various embodiments, the demonstration structure 3 is preferably made of cardboard and comprises a panel 8 curved in the form of a common tubular shape, substantially rectangular in plan, which defines the four demonstration sides of the display. Each side of the panel 8 has an opening 10 corresponding to the shelves 4.

Each second column 6 mentioned above is provided in each of the four inner corners of the panel 8. Said column 6, in particular, is formed by a vertical panel 8 ', in which a series of holes are provided, which are in the form of second outlets 6', and which are glued along inner corner sections of the panel 8 in order to connect the opposite sides of each section (see in this regard, figure 4). Each column 6 has an essentially triangular cross section.

In the embodiment considered here, the shelves 4 are essentially rectangular in shape, which corresponds to the top view in plan of the folded panel 8 and the corners 4 ", beveled so as to correspond to a triangular cross section of the columns 6.

In addition, each of the shelves has a central opening 4 ', through which, when the structure 3 is in the installed position, the first column 5 is passed. Said opening 4' is bounded by a closed portion 4a by which the shelf is fixed to the column 5.

Column 5 is formed from a vertical panel having four vertical sequences of holes that form the first outlets 5 '. Said panel is folded to form a common tubular shape that identifies four sides, each of which has one of the aforementioned hole sequences.

The upper end of the panel 8 is closed by a first cover 9, which has a substantially rectangular shape corresponding to a top plan view of the folded panel 8 and angles 9 ", beveled so as to correspond to a triangular cross section of the column 6. The cover 9 is mounted on the column 5 by means of it a closed section 9a provided in its central region, which, for the indicated purpose, is moved towards the upper end of the column 5. The closed section 9 defines a central opening 9 'formed in the lid 9 itself.

The second lid 10 is mounted on top of the first lid 9 and closes the panel 8 in the upper part, and forms a chamber 11 between the first and second lids, which sets the column 5 in fluid communication with the columns 6. In particular, said chamber 11 is in fluid communication with the first column 5 through the opening 9 'of the first cover and with the second column 6 through the corresponding channels formed by the beveled corners 6 "of the first cover 9, together with the corresponding inner corner portions of the panel 8.

In various embodiments, the first outlets 5 ′ are oriented so that air flows through them in a first direction, and the second outlets 6 ′, in turn, are oriented so that air flows through them in a second direction that is not parallel to the first direction.

The flows supplied by the first and second releases may have components transverse to the shelves, but they can be neglected here for ease of explanation.

In various embodiments, the first outlets 5 ′ of the first column 5 are arranged so that they identify the first flow vector K in the first direction and in accordance with the first air supply direction. The outlets 6 'of the second columns 6, in turn, are oriented so that they identify the second flow vector L in the second direction and in accordance with the second air supply direction.

In various embodiments, the second vector L has a nonzero component transverse to the first vector K, so that the air flow supplied through the second outlets interacts with the air flow supplied through the first outlets to provide air to the shelves suitable for preventing air from entering outside .

In various embodiments, the second vector L also has a nonzero component that is parallel and has the opposite direction with respect to the first vector K. In another embodiment, the second vector L, instead, has a nonzero component that is parallel and has the same direction as the first vector K.

As shown in a substantially plan view of the rectangular demo structure shown in FIG. 5, the outlets 6 ′ of the columns 6 are essentially facing the center of the rectangle, and the feed vector L defined by them is laid essentially along the diagonals of the latter, while the outlets 5 ′ of the column 5 are facing the respective sides of said rectangle, and the feed vector K defined by them is located in a direction transverse to said sides.

In various embodiments, the flow of air supplied through the second outlets interacts with the flow of air supplied through the first outlets, resulting in a swirling movement of air above the shelves to prevent air from entering from the outside.

In various embodiments, for each shelf, the total cross section of the output stream of the second outlets through which air enters it is less than the total cross section of the output stream of the corresponding first outlets. This makes it possible to obtain a dynamic configuration of fluid flows on each shelf, designed for the favorable formation of vortices. In the example shown in the figures, the outlets 5 ′ are wider than the outlets 6 ′, so that the total cross section of the output stream of the first outlets 5 ′ is approximately ten times larger than the total cross section of the output flow of the second outlets 6 ′.

The demonstration structure 3 described above may be interconnected with the thermodynamic assembly 2.

In the presented examples of an embodiment for the indicated purpose, on the panel 8, in the position corresponding to its lower end, the space provided for mounting the thermodynamic assembly 2 is determined. In the said embodiment, the panel 12 of the thermodynamic assembly 2 forms the lower surface of the demonstration space and has a central outlet 13, which, under the conditions when the assembly is connected to the structure 3, is moved to the lower end of the column 5 so as to install the fan of the thermodynamic assembly 2 in the flow message whose environment with the entire air distribution system design 3.

However, it is obvious that the first column 5 can be connected in any simple and quick way to the release of the thermodynamic assembly 2, provided that it can, on the other hand, be just as easily and quickly disconnected from it. With this in mind, the demonstration design can preferably be designed to work with various interchangeable thermodynamic assemblies.

Figure 4 shows the path of the flow of conditioned air, which is formed in the demonstration structure 3.

The air that was conditioned using the thermodynamic assembly 2 is supplied to the column 5. A portion of the air that flows through the column 5 is sequentially supplied over the various shelves 4 through the outlets 5 ′ in accordance with the supply vector K identified by them.

The rest of the air, after flowing through the entire column 5 in the supply direction, reaches the chamber 11 and is re-directed to the column 6 in the direction of return to the thermodynamic unit 2. The air that flows through the column 6 is then sequentially fed over various shelves 4 through outlets 6 ′ in accordance with the vector L identified by them.

As mentioned above, the flow of air supplied by the second columns 6 'interacts with the flow of air supplied by the column 5', to ensure that air encompasses the shelves to prevent the ingress of warm air from the outside. As can be seen in FIG. 4, in the illustrated embodiment, the flows supplied by column 6 interact with the flows supplied by column 5 to form air vortices.

As can be seen in the drawings, the shelves 4 have additional holes 4b located laterally relative to the central holes 4 ', which, when the structure 3 is in the installed position, correspond to each other and ensure the return of air supplied through the shelves to the thermodynamic unit 2 in the chamber, where the fan is installed (not shown in the drawings).

It should be noted that the solution illustrated in the drawings represents only one example of an embodiment of the description of the present invention.

Various embodiments may actually involve the use of a different number of second columns and / or additional first columns in accordance with a relative arrangement different from that shown in FIG.

In various embodiments, a plurality of second columns may be provided, each of which has respective sequences of second outlets, and the first column may have many sequences of first outlets. The different sequences of the first releases are designed to interact with the corresponding sequences of the second releases. In one embodiment, the first column is central to the shelves, and the second column is located around the first column.

In various embodiments, the shelves have, in a plan view from above, one of the following shapes: triangular, rectangular, square, pentagonal, hexagonal, etc., with the first column installed in the center and the second columns at each vertex.

In various embodiments, the second column may have one or more sequences of the second releases, and the first column may have one or more sequences of the first releases.

In various embodiments, a sequence of second releases interacts with only one sequence of first releases, or, in other words, a plurality of sequences of second releases interacts with only one sequence of first releases, and again, many sequences of first releases interacts with only one sequence of second releases.

In various embodiments, the demonstration structure comprises a first panel folded to form a common tubular configuration forming four open demonstration sides in which each second column is formed by a second vertical; a panel on which a series of holes is formed that forms the second outlets and which is glued to the inner corner portion of said first panel to connect the opposite sides of said portion. In the above-mentioned example of the embodiment, the first cap and the second cap are mounted on top of each other closer to the upper end of said first panel to receive a camera that establishes a fluid communication of the first column and at least one second column. In addition, in the aforementioned embodiment, the first column is formed by a third vertical panel, which has four vertical sequences of holes that form the first outlets, and is folded to form a common tubular shape that identifies the four sides, each of which has one of the mentioned sequences of holes wherein the first column extends through a central opening of said shelves.

The arrangement described above is particularly preferred as long as it provides adequate cooling for each shelf, even under conditions in which the shelves are fully occupied with the goods presented.

In the demo design discussed here, sequential flows in opposite directions, which form along the rows of shelves in the first and second columns, provide between the shelves the uniform effect of cooling by air with maintained thermal conditions. In fact, the shelves that receive cooler air from column 5, compared to other shelves, since they are closer to the thermodynamic unit 2, receive warmer air from columns 6 heated during flow along column 5 and along column 6. This the applicant determined that such a distribution of air flows further contributes to the formation of vortices on the shelves and guarantees effective cooling along the entire row of shelves.

Naturally, without limiting the principles of the invention, the details of the construction and embodiments may vary, even significantly, with respect to what has been presented here solely as a non-restrictive example, without thereby departing from the scope of the invention as defined in the attached claims.
