Description

Title of the invention: Device for separating a room comprising decorated glazing and a grid 1. Field of the invention

[0001] The field of the invention is that of the design and manufacture of elements for separating a room used to close an opening made in a wall of a room. 2. Prior art

[0002] Various elements for separating a room are commonly used in the construction sector to close an opening made in a wall of a room. These may include entrance doors, French windows, casement windows or fixed frames, etc.

[0003] These separation elements, in particular entrance doors, often comprise a leaf to which one or more panes of glass are attached.

[0004] The glazing may be single or multiple. In the latter case, it comprises several glass elements, for example two or three, separated two by two by a gas layer in particular so as to give it insulating properties (thermal and / or sound).

[0005] A glazed partition element, such as an entrance door, may comprise a grille.

[0006] When the glazing is single, the grid can be attached to one side of the glazing, generally the side facing the outside of the room, particularly when the separating element comprises an opening frame. When the glazing is multiple, the grid can be housed in the space provided between two glass elements or be attached to one side of the glazing.

[0007] Such a grille makes it possible to provide a decorative visual appearance and to improve the anti-burglary security of the door, or at the very least to improve the perception of security of the door, and thereby to improve its perceived quality.

[0008] However, in order to modify the decorative appearance given to a door by a grille, it is necessary to modify the grille. Thus, producing a range of doors offering different appearances requires multiplying the number of grille references, which represents a significant cost item. This is all the more true when the grilles are made by molding, each grille reference requiring the creation of an expensive mold.

[0009] In order to overcome these problems, it is known to create decorative patterns directly on the glazing. This can, for example, be achieved by creating a decoration on the glazing by depositing material on it, for example by screen printing, or by removing material such as by sandblasting. [OO1O] This approach offers great versatility in creating a multitude of decorative patterns at a lower cost compared to creating a multitude of grilles. However, the absence of a grille tends to reduce the perceived burglar-proof security of doors equipped with such glazing without a grille and, where appropriate, to erase the security aspect conferred by a grille.

[0011] The grilles can sometimes present, on one side, appearance defects which result from the method used for their manufacture. These can for example be shrinkage, lack of material, straws, burrs of the joint plane, deformations... These appearance defects can in whole or in part remain visible once the grille is secured to the door, which turns out to be unsightly and harms the perceived visual quality of the door. 3. Objectives of the invention

[0012] The invention aims in particular to provide an effective solution to at least some of these different problems.

[0013] In particular, according to at least one embodiment, an objective of the invention is to provide a technique which makes it possible to confer great versatility in terms of creating a decoration for a dividing element of a glazed room.

[0014] In particular, the invention aims, according to at least one embodiment, to provide such a technique which makes it possible to create a multitude of decorations at reduced cost.

[0015] Another objective of the invention is, according to at least one embodiment, to provide such a technique which makes it possible to improve the perceived quality of a room separation element in terms of safety and / or aesthetics of a device for separating a glazed room.

[0016] Another objective of the invention is, according to at least one embodiment of the invention, to confer a security aspect to a device for separating a glazed room.

[0017] Another objective of the invention is, according to at least one embodiment, to provide such a technique which makes it possible to limit the quantity of material used for the manufacture of a room separation element and to reduce the carbon emissions inherent in its manufacture. 4. Presentation of the invention

[0018] For this, the invention proposes a device for separating a room comprising a leaf and at least one glazing secured to said leaf, said glazing having at least one first decorative pattern, said device comprising at least one grid having a second decorative pattern, said at least one grid being integrated into said at least one glazing and / or placed on one side thereof, said at least one first decorative pattern said at least one glazing being configured to adorn said second decorative pattern of said at least one grid, said at least one first decorative pattern and said second decorative pattern forming a composite decoration.

[0019] Thus, according to this aspect, the invention consists of integrating within a separating element of a room, such as an entrance door for example, a glazing provided with a decorative pattern and a grid, also provided with a decorative pattern, placed in or on one side of the glazing. Thus, the invention consists of combining the use of a decorated glazing and a decorative grid.

[0020] This implementation makes it possible to create a pattern composed of the addition of the grid pattern and the glazing pattern, the glazing pattern decorating the grid pattern. In other words, the glazing pattern decorates the grid pattern to create a combined pattern.

[0021] The production of a combined pattern means that the pattern of the glazing is not produced randomly with a uniform or uneven distribution, such as for example the decorations of frosted, frosted, reflective solar control (stopsol®, Antelio®, etc.), Master-Ligne®, Master-Point®, etc. glazing. On the contrary, the decoration of the glazing is specifically adapted to the decoration of the grid to complete it. Thus, the decoration of the glazing adds to the grid elements which would conventionally be integral with the grid, such as for example solid parts, floral ornaments, peaks, etc., the production of which is particularly expensive.

[0022] By the combined use of the grid with decorated glazing, it is possible to generate a range of doors with varied decorations. Indeed, with a single standard grid with a simple decoration, it is possible to produce doors with different appearances by using glazing with different decorations made simply and at low cost by adding or removing material. It is thus possible to generate a range effect at low cost by using a standard grid made in large quantities for a plurality of different doors. Indeed, the standard grid, preferably with a simple pattern, made with little material and therefore light, will be produced at low cost while benefiting from a scale effect. The invention thus makes it possible to produce at low cost elements for separating a room benefiting from a very good perceived quality in terms of aesthetics.

[0023] It is also possible to further increase versatility through plays on colors and contrasts generated by the glass decoration.

[0024] Furthermore, the integration of a grid makes it possible to reinforce the perceived quality of the separation element in terms of security even if the grid is only ornamental and is not intended to provide an anti-burglary function. It can also make it possible to reinforce the resistance to burglary of the door when the grid is designed for this purpose.

[0025] The use of a less massive grid made with little material could be detrimental to the qualitative aspect of the door in terms of security. However, the combined use of a grille and a glazing decoration makes it possible to compensate for the reduction in the grille section by an optical effect provided by the glazing decoration. The use of a simple grille made with little material makes it possible to reduce production costs by reducing raw material consumption. It also makes it possible to reduce carbon emissions. In addition, if the grille is made by molding, it only requires the creation of a mold for the production of a wide range of doors with different decorations. It is thus possible to further reduce the production cost of the doors.

[0026] The combined use of decorated glazing and a grid therefore allows:

[0027] - to offer great versatility in the creation of decorations;

[0028] - to give the door a good perceived quality both in terms of aesthetics and security terms;

[0029] - to reduce production costs;

[0030] - to reduce the environmental impact by reducing material consumption first and greenhouse gas emissions.

[0031] According to a preferred characteristic, said at least one first decorative pattern of said glazing has a path determined as a function of the path of said second decorative pattern of said at least one grid such that said at least one first decorative pattern adorns said second decorative pattern.

[0032] Thus, the decoration of the glazing is designed to adorn the pattern of the grid by completing it to give from a distance the illusion that the decoration is composed solely of the grid.

[0033] According to a preferred characteristic, said at least one first decorative pattern comprises at least one deposit of material and / or at least one removal of material.

[0034] According to a preferred characteristic, said glazing is clear and said grid has appearance defects, said at least one first decorative pattern at least partially concealing said appearance defects of said grid.

[0035] It is thus possible to conceal defects in the grid and to improve the aesthetic qualities of the separation element.

[0036] According to a preferred characteristic, said appearance defects of said grid are oriented towards the side of said device intended to be placed towards the interior of said room.

[0037] According to a preferred characteristic, said grid is made of metal, for example of aluminum alloy (in particular by casting) or steel (in particular by ironwork), wood or any other suitable material.

[0038] The invention also covers a glazing for a device according to any one of the variants set out above. Such a glazing has at least one first decorative pattern, said glazing comprising at least two glazed panels, separated by at least one space, forming a multiple glazing, said glazing comprising at least one grid housed in said at least one space, said at least one grid having a second decorative pattern, said at least one first decorative pattern of said at least one glazing being configured to adorn said second decorative pattern of said at least one grid, said at least one first decorative pattern and said second decorative pattern forming a composite decoration.

[0039] The invention also covers a method of manufacturing a separation device according to any one of the variants set out above, said method comprising at least:

[0040] - a step of producing said leaf,

[0041] - a step of producing said at least one grid;

[0042] - a step of producing said at least one glazing having said at least one first decorative motif;

[0043] - a step of assembling said at least one glazing and said at least one grid said leaf, said grid being integrated into said glazing and / or placed on one side thereof, said at least one first decorative pattern of said at least one glazing being configured to adorn said second decorative pattern of said at least one grid, said at least one first decorative pattern and said second decorative pattern forming a composite decoration.

[0044] According to a preferred characteristic, said at least one first decorative pattern comprises at least one deposit of material(s) for example obtained by screen printing. Other methods could be used such as for example printing, glass modeling, engraving, etc.

[0045] According to a preferred characteristic, said at least one first decorative motif comprises at least one removal of material obtained for example by sandblasting or any other suitable method.

[0046] According to a preferred characteristic, said step of producing said at least one glazing unit comprises a step of producing at least one multiple glazing unit comprising at least two glazed panels separated by at least one space, said step of producing said glazing unit comprising a step of integrating said at least one grid into said at least one space. 5.

[0064] 6. Description of particular embodiments 6.1. Device for separating a room

[0065] In relation to Figures 1 to 15, examples of embodiments of a device for separating a room are presented. The embodiments described below relate to entrance doors. The elements for separating a room according to the invention are not, however, limited to entrance doors but include all types of joinery such as French windows, balcony doors, service doors, interior doors, communication doors, tertiary or industrial doors, gates (garage, fence, etc.), windows (casement, sliding, roof, fixed frame, etc.).

[0066] An entrance door 1 conventionally comprises:

[0067] - a frame 10 delimiting an opening 11, and

[0068] - a leaf 12 secured to the frame 10 in a movable manner between a position of the opening 11 and the opening 11 release positions.

[0069] The leaf 12 comprises a frame 120 delimiting an opening 121 housing a glazing 123. In this embodiment, the leaf 12 comprises a bend 123. In variants, the frame 120 could delimit several openings 121 and the leaf 12 consequently comprise several glazings 123.

[0070] The leaf 12 may or may not be of the opening frame type. When the leaf 12 is not of the opening frame type, the glazing 123 is housed directly in the opening 121 of the frame 120 of the leaf 12, as shown in [Fig. 1]. When the leaf 12 is of the opening frame type, as in [Fig. 2], it comprises at least one opening frame 124 carrying at least one glazing 123, said at least one opening frame 124 being movable to allow one or more openings 123 formed in the frame 120 of the leaf 12 to be released or closed.

[0071] The glazing 123 of the leaf 12 may be simple and comprise a single glass element. The glazing 123 may alternatively be multiple, as shown in Figures 3 and 4. In this case, it comprises at least two glass elements 1230, 1231, for example two or three, arranged parallel to each other and separated two by two by a space 1232, for example a gas layer in particular so as to give it insulating properties (thermal and / or sound).

[0072] The leaf 12 also comprises a grid 13. In a variant, the leaf 12 could comprise several grids, in particular when it comprises several glazings.

[0073] The grid 13 can be made of metal, wood or any other suitable material. When it is made of metal, it can be manufactured for example in a foundry.

[0074] The grid 13 can be placed on one side or the other of the glazing 123, that is to say on the side of the glazing 123 intended to be oriented towards the interior of the room or on the side of the glazing intended to be oriented towards the exterior of the room, which is most often the case. This can be the case whether the glazing is single or multiple. When the glazing 123 is multiple and comprises at least two glass elements 1230, 1231 separated by a space 1232, the grid 13 can be housed inside this space 1232.

[0075] The grid 13 is composed of a decorative pattern. The appearance of this pattern is defined by its outline, i.e. its design. [Fig. 5] illustrates an example of a grid 13 whose pattern is composed of a plurality of diamonds 130 delimited by bars 131. [Fig. 6] illustrates another example of a grid 13 whose decorative pattern is more elaborate and has more complex contours. These two grids 13 are only illustrative examples and many other grids with different patterns can be imagined.

[0076] With these two basic grids 13, it would not be possible according to the prior art to propose only one range of doors with two different aspects. As will become more clear later, thanks to the invention, it is possible to compose a range of doors with a plurality of different aspects from these two basic grids 13 alone.

[0077] For this, the glazing 123 also comprises at least one decorative pattern. The appearance of this pattern is defined by its outline, i.e. its design. The decorative pattern can be created by adding material or removing material, for example by screen printing or sandblasting. Other methods of creating the decorative pattern of the glazing could of course be implemented.

[0078] It may be envisaged to produce decorative patterns on different faces of the glazing.

[0079] The decorative pattern produced on the glazing 123 is not composed randomly. with a uniform distribution or not, such as for example the decorations of classic glazing of the frosted, frosted, reflective type with solar control (stopsol®, Antelio®...), Master-Ligne®, Master-Point®...

[0080] On the contrary, the decoration of the glazing 123 is, according to the invention, specifically adapted to the decoration of the grid 13 in order to complete it. Thus, the decoration of the glazing 123 adorns the decoration of the grid 13 in order to add elements which would conventionally be integral with the grid 13, such as, for example, solid parts, floral ornaments, peaks, etc., the production of which is particularly expensive insofar as it requires producing a specific mold for each variant of decoration when the grid is produced by molding or adding decorative detail elements, for example, by welding.

[0081] In other words, the decorative pattern of the glazing has a path determined according to the path of the decorative pattern of the grid in such a way that the decorative pattern of the glazing adorns the decorative pattern of the grid.

[0082] [Fig.7] illustrates:

[0083] - on the left an example of decorative pattern 1233 produced on glazing 123,

[0084] - in the center a first example of grid 13 presenting a decorative pattern 132, and

[0085] - on the right how this decorative motif 1233 comes to adorn the motif of the grid 13 for form a composite decoration. The decorative motif 1233 of the glazing 123 adds to the decorative motif of the grid 13 such as floral motifs at the ends of the diamonds of the grid 13.

[0086] [Fig.8] illustrates:

[0087] - on the left another example of decorative pattern 1233 produced on glazing 123,

[0088] - in the center a first example of grid 13 presenting a decorative pattern 132, and

[0089] - on the right how this decorative motif 1233 comes to adorn the motif of the grid 13 for form a composite decoration. The decorative motif 1233 of the glazing 123 adds to the decorative motif of the grid 13 like peaks in the middle of the sides of the diamonds.

[0090] [Fig.9] illustrates:

[0091] - on the left another example of decorative pattern 1233 produced on glazing 123,

[0092] - in the center a first example of grid 13 presenting a decorative pattern 132, and

[0093] - on the left how this decorative motif 1233 comes to adorn the motif of the grid 13 for form a composite decoration. The decorative motif 1233 of the glazing 123 adds to the decorative pattern of grid 13 such as floral patterns at the ends of the diamonds 130 of grid 13 as well as peaks in the middle of the sides of the diamonds 130.

[0094] [Fig. 10] illustrates:

[0095] - left another example of decorative pattern 1233 produced on a glazing 123;

[0096] - in the center a first example of grid 13 presenting a decorative pattern 132, and

[0097] - on the right how this decorative motif 1233 comes to adorn the motif of the grid 13 for form a composite decoration. The decorative pattern 1233 of the glazing 123 adds to the decorative pattern of the grid 13 as solid parts with a translucent outline in the center of each diamond 130 of the grid 13.

[0098] These examples show that with a single basic grid, it is possible to compose not just one type of door but, for example, four types of doors with different appearances.

[0099] [Fig. 11] illustrates:

[0100] - on the left another example of decorative pattern 1233 produced on glazing 123;

[0101] - in the center a second example of grid 13 presenting a decorative pattern 132, and

[0102] - on the right how this decorative motif 1233 comes to adorn the motif 132 of the grid 13 to form a composite decoration. The decorative pattern 1233 of the glazing 123 adds to the decorative pattern 132 of the grid 13 as solid parts at four corners of the grid 13.

[0103] [Fig. 12] illustrates:

[0104] - on the left another example of decorative pattern 1233 produced on glazing 123,

[0105] - in the center a second example of grid 13 presenting a decorative pattern 132, and

[0106] - on the right how this decorative motif 1233 comes to adorn the decorative motif 132 of the grid 13 to form a composite decoration. The decorative pattern 1233 of the glazing 13 adds to the decorative pattern 132 of the grid 13 like leaves to certain bars of the grid 13.

[0107] [Fig. 13] illustrates:

[0108] - on the left another example of decorative pattern 1233 produced on glazing 123,

[0109] - in the center a second example of grid 13 presenting a decorative pattern 132, and

[0110] - on the right how this decorative motif 1233 comes to adorn the decorative motif 132 of the grid 13 to form a composite decoration. The decorative pattern 1233 of the glazing 123 adds to the decorative pattern 132 of the grid 13 as turned elements to certain bars of the grid 13 in addition to those integral with the grid 13.

[0111] These examples show that with a single basic grid 13 of a different shape from the first, it is possible to compose not just one type of door but for example three types of door with different appearances.

[0112] Since the cost of producing a pattern on the glazing is much lower than that of producing a grid, the technique according to the invention makes it possible to offer a wide range of doors at low production costs. The cost is further reduced since the production of a single grille for several types of doors allows this grille to be produced in large quantities and the cost to be reduced through scale.

[0113] These composite decorations, when the door is viewed from the front with a distance of a few meters, for example 1 or 2 meters, give the illusion that the motif decorating the door is created solely by means of the grid.

[0114] Whether the grid is positioned in front of or behind the single or multiple glazing or whether it is housed inside a multiple glazing, there is a space between the decorated glazing and the grid. Thus, when the observer of the door moves relative to the door, he can observe, by a parallax effect, the composite pattern deforming. In this sense, the invention makes it possible to create a dynamic composite decoration.

[0115] It is possible that the grid 13 has, on one and / or the other of its faces, appearance defects whose presence results from the manufacturing process. These may for example be shrinkage, lack of material, straws, joint plane burrs, deformations, etc. The decoration produced on the glazing can thus be skillfully configured to conceal all or part of these appearance defects. This is particularly useful when the glazing is clear.

[0116] Figures 14 and 15 illustrate examples of glazing according to the prior art, respectively frosted glazing and glazing with regular points.

[0117] [Fig. 14] shows on the right the result obtained by superimposing the grid in the center and the glazing on the left. It can be seen that this superposition does not lead to the creation of a composite decoration within the meaning of the invention since the decoration of the glazing is not designed specifically to adorn the decoration of the grid.

[0118] [Fig. 15] shows on the right the result obtained by superimposing the grid in the center and the glazing on the left. We observe once again that this superposition does not lead to the creation of a composite decoration within the meaning of the invention since the decoration of the glazing is not designed specifically to adorn the decoration of the grid.

[0119] Indeed, in these two cases, the decoration of the glazing does not dress, i.e. complete, the decoration of the grid to give the illusion, when viewed from a distance, that the composite decoration is only achieved by means of the grid.

[0120] 6.2. Method of manufacturing a device for separating a room

[0121] The invention also relates to a method of manufacturing a separation device.
