INSULATED GLAZING FOR THE PRODUCTION OF WALLS OR DOORS FOR REFRIGERATED DISPLAY CASES

FIELD OF THE INVENTION

The present invention is generally applicable to the technical field of glazing technology and relates in particular to an insulating glazing for the production of walls or doors for refrigerated showcases, as well as a door or a wall for a refrigerated showcase which includes such an insulating glazing.

DEFINITIONS

By double glazing (or double glazing or double glazing) is meant an insulating multilayer assembly formed by a set of two or more sheets of glass or other transparent materials that are opposed, spaced apart and connected along their perimeter to form a sealed closed Define inner chamber that is filled with air, with dry air or with a dry gas that is heavier than air.

Resin is understood to mean any polymeric material that is liquid or semi-liquid at the time of application, as described below, and which then cures in situ.

In the present text, the term "compatible materials" or the like means materials that have a chemical and / or physical compatibility, ie materials that, after coupling, lead to a connection that is suitable for the transmission of traction or Cutting forces through the contact surface.

In the present text is with the term "transparent" or the like, which refers to a material, the ability of such a material to be traversed by light without it being scattered, or the ability of such a material to be passed by Light to be traversed in a diffuse way. In other words, the term "transparent" includes both proper transparency and translucency.

BACKGROUND OF THE INVENTION

It is known that in the shops with perishable goods, especially food, refrigerated display cases are used to make the various products available to the consumer. In order to ensure good visibility and effectiveness of the displays, such displays usually have both fixed walls and movable locking elements or optically transparent doors.

In general, such walls and / or doors are made from double glazing, generally adding handles, hinges or other accessories suitable for mutual assembly to the walls and / or doors and / or to the refrigerated display case.

In order to increase the visibility of the products on display, insulating glazing with essentially transparent visible spacer elements are known.

For example, from the application WO 2014/009244 an insulating glazing with spacer elements made of PMMA or transparent polycarbonate is known.

In practice, such known insulating glazing has shown little attractiveness on the market, which is essentially due to the lack of transparency of the materials used. Such a disadvantage is also due to the fact that the spacer elements made of PMMA or polycarbonate are glued to the panes of the insulating glazing. In fact, the presence of glue degrades the aesthetics of such an insulating seal.

glazing.

In order to overcome such disadvantages, an insulating glazing is known from the patent EP2878233, wherein the spacer element consists exclusively of substantially transparent, hardening resin, generally acrylic or polyurethane. The latter is poured into a mold in liquid form, the edges of the glass panes then being dipped in and provided with the desired spacing. After the resin has hardened, the mold is removed from the double glazing. It is obvious that in this case the spacer element also serves as a seal for the insulating glazing.

Despite the good visibility, such insulating glazing has some disadvantages.

A first disadvantage is the fact that, during the manufacture of the insulating glazing, the glass panes must be held in position at a predetermined distance until the resin is completely cured.

Another disadvantage is the fact that the resin also adheres to the mold and thus hinders the separation of the double glazing from its shape after the resin has cured.

Because of this problem, resins with limited adhesiveness are used to enable the mold to be removed without damaging it or the double glazing.

As is known, the adhesive force is proportional to the area wetted by the resin, therefore in this latter case it is necessary to use a large amount of resin in order to enable a stable connection between the panes of glass, with an obvious increase in costs, both in terms of the cost of the resin and the increase in curing time.

In addition, the spacer-sealing element produced in this way is bulky, in particular it has a high height, which makes the insulating glazing aesthetically unattractive. In particular, the bulky sealing material element leads to optical distortions which impair the aesthetic appearance and the optical continuity effect desired of displays.

Over time, the resin then loses its effectiveness, which brings the risk of air penetration and / or the breakage of the insulating glass with it.

Another disadvantage is the fact that after the mold has been separated from the insulating glazing, an additional cleaning and reconditioning process of the mold is required before it can be used again.

DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS

With reference to the aforementioned figures, an insulating glazing 1 is described, preferably comprising a pair of opposing plate-shaped elements 10, 20 and an inner chamber 2 which is arranged between the plate-shaped elements 10, 20.

The plate-shaped elements can be essentially transparent and / or translucent plates 10, 20. For example, the plates 10, 20 can be made of glass or a plastic such as polymethyl methacrylate (PMMA), polycarbonate or the like.

Although in the following we refer to panels for the sake of simplicity, it is understood that the insulating glazing 1 can comprise any panel-shaped element without departing from the scope of the appended claims.

Each plate 10, 20 can define corresponding planes which run essentially parallel to one another, so that the plates 10, 20 have a predetermined mutual spacing d, for example from 6 mm to 30 mm.

It will be understood that the plates 10, 20 can be substantially flat or in any shape, for example curved, and they may or may not be substantially parallel to one another. For example, the insulating glazing 1 can have two flat and parallel plates 10, 20 (FIG. 1) or two curved and parallel plates 10, 20 (FIG. 2).

Each plate 10, 20 can have an edge region 11a and 21a, which in turn has a respective

which may comprise opposite peripheral edges 11, 21, and a corresponding pair of visible surfaces 12, 13 and 22, 23, substantially perpendicular to the peripheral edge 11 and to the peripheral edge 21.

As shown in particular in the accompanying figures, mechanical connecting means 30 of the plates 10, 20 can be provided and a sealing resin 42 to cooperate with the mechanical connecting means 30 to seal the inner chamber 2 so that it remains substantially isolated.

In principle, the mechanical connecting means 30 can comprise a substantially semi-rigid or rigid longitudinal profile 31 for connecting the plates 10, 20 according to the respective peripheral edge 11, 21, while the adhesive sealing resin 42 between the visible surfaces 13, 23 of the peripheral edges 11, 21 of the Plates 10, 20 and the profile 31 can be inserted, as explained in more detail below.

In particular, the longitudinal profile 31 can comprise a substantially flat or slightly curved main body 32, which can have a central section 320 and two sections 33, 34, each of which has a substantially longitudinal seat 33a, 34a with a "U" Form extending substantially transversely or perpendicularly to the main body 32 to receive the edge region 11a and 21a of the plates 10, 20, respectively. In particular, the longitudinal seats 33a, 34a can accommodate a corresponding section 14, 24 of these edge regions 11a, 21a.

Correspondingly, the sections 33, 34 can be arranged at opposite ends with respect to the central section 320.

In particular, each of the seats 33a, 34a may include a respective top or bottom wall 35 substantially parallel to the central portion 320 and a corresponding pair of side walls 36, 36a and 360, 360a that may oppose each other and extend across the main body 32 .

As soon as the plates 10, 20 are inserted into the seats 33a, 34a of the longitudinal profile 31, the side walls 36, 36a and 360, 360a can face the plates 10, 20 and in particular their visible surfaces 12, 13, 22, 23, while the wall 35 may face or be in contact with the edges 11 or 21.

It goes without saying that the wall 35 is a lower or upper wall, depending on the orientation of the profile 31. The seats 33a, 34a can be essentially concave, the concavity being directed towards the plates 10, 20.

In addition, the middle section 320 of the main body 32 can have an inner surface 320aa facing the working chamber 2, which can therefore lie between the inner side walls 36a, 360a of the seats 33a, 34a.

In any case, the above-described configuration of the seats 33a, 34a should not be considered limiting. For example, the side walls 36, 36a and 360, 360a can have different heights and / or configurations.

Suitably, as shown for example in Figs. 3B to 3E shown, the side walls 36, 36a and 360, 360a, and preferably the entire profile 31, can be made of a rigid or semi-rigid polymer material in order to hold the Plates 10, 20 to be elastically deformed. For example, such a polymer material can have a flexural modulus measured in accordance with ISO 527-2 of 1000 MPa to 3000 MPa, preferably from 1200 MPa to 2500 MPa.

In addition, the side walls 36, 36a and 360, 360a can further comprise one or more fastening elements 37. The latter can for example comprise appendages or projections which preferably extend inward and are in contact with the respective edge regions 11a, 21a of the plates 10, 20 in order to act against them by friction. For example, the fastening elements 37 can be a plurality of segments or a plurality of points that protrude from the side walls 36, 36a and 360, 360a.

The fastening elements 37 are advantageously arranged on both walls 36, 36a and 360, 360a.

In a preferred, but not limiting embodiment, the fastening elements 37 can comprise or consist of a longitudinal bead which preferably extend over the entire length of the side walls 36, 36a and 360, 360a.

The fasteners 37 can be integrally coupled to the sidewalls 36, 36a and 360, 360a or monolithic therewith, e.g., they can be coextruded therewith. The fastening elements 37 can preferably be coextruded with the longitudinal profile 31.

The force of the side walls 36, 36a and 360, 360a on the fastening elements 37 against the glass of the plates 10, 20 enables the plates 10, 20 to be connected to the longitudinal profile 31 and thus to prevent their mutual loosening.

In addition, such an effect prevents the polymer resin 42 from passing into the space 340 between the side walls 36, 36a; 360, 360a and the plates 10, 20 to seal the inner chamber 2 further.

Basically, the polymer resin 42 and the side walls 36, 36a; 360, 360a with the fastening elements 37 both for connecting the plates 10, 20 and for sealing the inner chamber 2 together.

To fulfill the above-mentioned function, the fastening elements 37 can be made of a substantially soft polymer material in order to be able to move under the pressure of the opposing side walls 36, 36a; 360, 360a to permanently deform against the plates 10, 20.

In addition, such an essentially soft polymer material can have a Shore A hardness of 40 to 80, measured in accordance with ISO 48.

Preferably, both the fastening elements 37 and the longitudinal profile 31 can be produced from compatible, preferably identical, polymeric materials. In addition, these materials or such a material can preferably be essentially transparent.

Such a material can advantageously be selected from the group consisting of polycarbonate, polymethyl methacrylate, acrylates, PVC, PA, polyolefins and polyesters.

In addition, in a preferred but non-limiting embodiment, the distance d2 between the opposite side walls 36, 36a; 360, 360a may be slightly less than the thickness s of the plates 10, 20, for example 1-2 mm.

The adhesive sealing resin 42 can be introduced into the inner chamber 2 corresponding to the sections 14, 24 in contact with the plates 10, 20 and the longitudinal profile 31.

The adhesive sealing resin 42 may be a substantially transparent polymer resin.

In particular, the adhesive sealing polymer resin 42 may completely cover the inner side walls 36a, 360a of the seats 33a, 34a and the inner surface 320a of the central portion 320 of the main body 32.

Due to the presence of the longitudinal profile 31, a reduced amount of adhesive resin 42 can be used appropriately. In fact, the height H2 of the adhesive sealing resin 42 from the main body 32 can be particularly reduced.

This property, as well as the fact that both the adhesive sealing resin 42 and the longitudinal profile 31 are transparent, enable a cost saving and an improvement in the aesthetic attractiveness in relation to the insulating glazing known from the prior art.

Thanks to this property, it is possible, for example, to achieve an effect of high visual continuity after arranging two or more insulating glazings 1 next to one another.

len.

Preferably, but not exclusively, the height H2 may be substantially constant for all of the adhesive sealing resin 42. Indeed, if the longitudinal profile has a slightly curved shape, the height of the adhesive sealing resin 42 between the central portion 320 and the portions 33, 34 can vary slightly.

Preferably, the height of the adhesive sealing resin 42 corresponding to the inner surface 320a of the central portion 320 of the main body 32 can be considered to be such a height H2.

For example, the adhesive sealing resin 42 once crosslinked can have a thickness which essentially corresponds to the distance d between the plates 10, 20, and a height H2 of 5 mm to 20 mm, preferably of approximately 15 mm.

Therefore, the adhesive sealing resin 42 may be present in such an amount that it adheres to the inner side walls 36a, 360a and to the plates 10, 20 for a short portion 15, 25 above them, so that the height H2, the the adhesive sealing polymer resin 42 with respect to the main body 32 is slightly higher than the height H1 of the inner side walls 36a, 360a with respect to the main body 32.

For example, the inner side walls 36a, 360a can have a height H1 of 3 mm to 12 mm, preferably 3 mm to 8 mm.

In particular, the section 15, 25 can have a height H3 less than 10 mm, preferably less than 8 mm and even more preferably less than 5 mm.

According to a certain aspect of the invention, the height H2 can be substantially equal to the sum of the height H1 and the height H3. For example, the inner side walls 36a, 360a can have a height H1 of about 10 mm, while the section 15, 25 can have a height H3 of about 5 mm, so that the adhesive sealing polymer resin 42, once cured, has a height H2 of has about 15 mm.

The substantially transparent adhesive sealing polymer resin 42 can be any resin or mixture of curing resins known to those skilled in the art, for example, a thermoplastic resin that cures by cooling, a resin that cures by vulcanization, a resin or a resin several resins that cure by crosslinking, or a mixture thereof.

The resin can preferably cure by crosslinking. For example, a single or multi-component resin can be used, which is introduced in liquid or semi-liquid form at room temperature, which hardens by crosslinking, e.g. by thermal activation or UV activation or simply after an incubation period after the components have been mixed.

Examples of such resins are acrylic, polyurethane, polyester resins or a mixture of one or more thereof.

Correspondingly, the resin can have a high adhesive force on the glass, preferably the adhesion of the adhesive sealing resin 42 on the surfaces 13, 23 and on the profile 31 can be essentially irreversible.

The resin can be a modified resin in order to increase the adhesion to the glass, as is known to those skilled in the art.

For example, the resin can be modified by introducing groups with high compatibility with the glass and the material of the profile 31 in order to increase the adhesion of the adhesive sealant resin 42 to the plates 10, 20 and the longitudinal profile 31.

A non-exhaustive example of such a resin modification is silanization.

In terms of manufacturing technology, the plates 10, 20 can first be provided and mechanically coupled with the aid of the mechanical connecting means 30, as described above.

For this purpose, the plates 10, 20 can be arranged vertically, while the longitudinal profile 31 can be directed downwards, so that the former define the side walls of the inner chamber 2 and the latter define the base wall of the inner chamber 2.

After the plates 10, 20 have been connected to the profile 31, the inner surface 320a of the main body 32, the inner side walls 36a, 360a and the sections 15, 25 of the inner surfaces 13, 23 of the plates 10, 20 define a working space 2a for Adhesive sealing resin 42 received.

Appropriately, the adhesive sealing resin 42 can be introduced into the working space 2a in liquid or semi-liquid form and then cured, as explained in more detail below.

In particular, the working space 2a can be delimited laterally by the inner side walls 36a, 360a, by the inner surfaces 13, 23 of the plates 10, 20 and by plugs 5, downward by the inner surface 320a of the main body 32, while it is above, ie in the direction of the inner chamber 2, can be open.

In this way, the increase in the amount of adhesive sealing resin 42 can correspond to an increase in the height H2, and vice versa.

Possibly the longitudinal profile 31 can be substantially horizontal or slightly inclined during the step of introducing the adhesive sealing resin 42, so that the sealing resin 42 has the height H2 and the top side 41 of the sealing element 42 substantially constant along the entire development is essentially flat. In other words, by gravity, such a surface 41 facing the inner chamber 2 can be substantially flat and orthogonal to the surfaces 13, 23 of the plates 10, 20.

After the adhesive sealing resin 42 has hardened, the plugs 5 can be removed in order not to change the aesthetic appearance of the insulating glass 1.

According to a certain aspect of the invention, the introduction or pouring of the adhesive sealing resin 42 can take place by means of a funnel-shaped device 50, which can therefore be fluidically connected to the working space 2a via a fluidic connecting line 3.

The longitudinal profile 31 can have a longitudinal section 38 coupled to the plates 10, 20 and a section 39 protruding therefrom in order to define the fluidic connecting line 3. In other words, the longitudinal profile 31 can have a significantly greater length than the section 14, 24.

In particular, the longitudinal section 38 of the longitudinal profile 31 can have an end 38 a opposite the section 39. To match this, the plug 5 can be placed at the end 38a of the longitudinal profile 31, while the funnel-shaped device 50 can be placed corresponding to the section 39.

Therefore, the adhesive sealing resin 42 can be introduced with the aid of the funnel-shaped device 50, which can therefore have an inlet 51 and an outlet 52 for the liquid resin.

On the other hand, the device 50 can comprise a lower portion 53, which is formed in opposite directions with respect to the longitudinal profile 31 in order to couple therewith and prevent the escape of liquid resin, and an opposite lower portion, which the outlet 52 for the liquid resin can define.

The device 50 can therefore be suitably coupled to the section 39 so that the outlet 52 is fluidically connected to the working chamber 2a, so that the liquid resin flows into the working chamber 2a along the longitudinal profile 31 and in particular along the inner surface 320a thereof .

In this way, the liquid resin can wet the inner surfaces 13, 23 only in the vicinity of the edge regions 11a, 21a in order to avoid the risk of soiling the plates 10, 20.

avoid.

The device 50 can possibly be releasably coupled to the longitudinal profile 31 in order to remove the former after the introduction of the adhesive sealing resin 42 into the chamber 2a and / or after the end of the curing step.

According to a certain aspect of the invention, the section 39 can be removed from the section 38, for example by cutting the longitudinal profile 31 corresponding to the end of the section 14, 24 of the plates 10, 20.

In this way, the device 50 can be removed from the section 38 of the longitudinal profile 31 after the removal of the section 39. This feature enables the production times for the insulating glazing 1 to be particularly reduced.

The curing can take place by crosslinking in situ and / or in another processing environment.

Thanks to the features mentioned above, it is possible to use a reduced amount of hardening resin 42, which leads to a considerable saving in the manufacturing times of the insulating glazing 1. In fact, the time it takes for the hardening sealing resin 42 to cure increases as the amount increases.

In addition, the presence of the longitudinal profile 31 makes it possible to move and / or rotate the insulating glazing without waiting for the hardening sealing resin 42 to fully cure, whereby the manufacturing times of the insulating glazing 1 are shortened.

In the present text, the coupling for the section 14, 24 of the edges 11, 21 of the plates 10, 20 is described, ie for one side of the insulating glazing 1. It goes without saying that what has been described is realized for one or more sides of the insulating glazing can be, possibly on all sides.

After the full or partial hardening of the adhesive sealing resin 42 realized on the section 14, 24 of the edges 11, 21 of the plates 10, 20, the insulating glazing 1 can be rotated in the plane defined by the plates 10, 20 and similar to that described above other portions of the edges 11, 21 of the plates 10, 20 can be coupled.

It is understood that such an embodiment is not restrictive, rather it is possible to produce an insulating glazing 1 which has any, not necessarily rectangular, shape or comprises several glass panes, glass panes and plates made of plastic, plates made of polymer material. In addition, the plates 10, 20 need not be flat, e.g. they can be curved and / or rounded.

In addition, it is understood that the insulating glazing 1 can have the panels 10, 20 coupled with the profile 31 and the adhesive sealing resin 42 along the entire peripheral edge 11, 21 or along one or more sections 14, 24 thereof.

For example, the insulating glazing 1, as shown in Fig. 6, some portions 14, 24 of the peripheral edges 11, 21, for example a pair of opposite sides, which are coupled via the profile 31 and the adhesive sealing resin 42, while the remaining portions of the peripheral edges 11, 21, ie the other two opposite sides, are coupled in a known manner to a metallic spacer element S, which may be filled with salts.

In any case, the insulating glazing 1 can be particularly useful for making walls or doors 101 for a refrigerated showcase or display 100.

To produce the wall or door 101, it may be sufficient to connect one or more accessories, such as handles or hinges, to the insulating glazing 1.

In particular, a refrigerated showcase 100 can contain one or more doors or flaps 101

adjacent to it, which are realized starting from the insulating glazing 1, so that each door or flap 101 has the side edges in contact with the side edges of the adjacent doors or flaps.

Thanks to the particular configuration of the double glazing 1, the visible surface of the refrigerated display case can be substantially transparent, preferably completely transparent, without interrupting the visual continuity between a door or cover 101 and the next adjacent one.

From the above, it will be seen that the invention achieves the intended aims.

The invention is susceptible to numerous changes and variations, all of which are within the scope of the appended claims. All indications can be replaced by other technically equivalent elements, and the materials can vary as required without departing from the scope of the invention, which is defined by the appended claims.
