Description

Frame structure of a display unit, and display unit comprising such a frame structure.

The present invention relates to a frame structure of a display unit, and a display unit comprising such a frame structure.

The field of the invention is that of display units, in particular, but in no way limiting, for the construction of temporary exhibition stands. These display units can for example comprise display elements such as a printed canvas or an electronic display screen, for example of the LED type.

State of the art

Today's display units increasingly include trim elements.

A dressing element can serve as a display element. In this case, the covering element is fixed on a structure of the display unit, and comes to cover one, or more, visible faces of the display unit, so that the covering element is visible in the configuration of use of the display unit.

A trim element can also serve as a protective or masking element, for example to cover a rear face of a display unit.

In both cases, it is crucial to maximize the surface covered of the structure by the cladding element. However, current solutions do not allow optimum covering of the structure of a display unit by a covering element.

In addition, it is difficult to set up and remove a dressing element in the current solutions of display unit structures.

An object of the present invention is to remedy at least one of these drawbacks.

Another object of the invention is to propose a frame structure making it possible to facilitate the positioning and removal of a covering element on said structure.

Yet another object of the invention is to propose a frame structure making it possible to maximize the possible covering surface by a covering element.

It is also an object of the present invention to provide a frame structure making it possible to put in place and remove a trim element even when said frame structure is in the assembled configuration.

• disposée sur ledit bord latéral du côté de ladite première face,
• ouverte vers ladite bordure longitudinale extérieure dudit bord latéral, et
• inclinée, au moins localement, suivant une direction formant un angle compris entre 30 et 60 degrés par rapport à ladite première face.

The invention makes it possible to achieve at least one of these objects by a frame structure of a display unit, said frame structure comprising at least one side edge, said side edge comprising an outer longitudinal edge of the outer side of said frame structure, and an interior longitudinal edge on the interior side of said frame structure, said lateral edge being provided with at least one fixing groove for a covering element intended to extend from the side of a first face of said frame structure, towards the inside of said frame structure, from said lateral edge, characterized in that at least one fixing groove, called inclined, is:

• arranged on said lateral edge on the side of said first face,
• open to said outer longitudinal edge of said side edge, and
• tilted, at least locally, in a direction forming an angle of between 30 and 60 degrees with respect to said first face.

The frame structure according to the invention allows greater ease of installation and removal of a trim element, since the inclined fixing groove will remain accessible even when the frame structure is in the assembled configuration with another frame structure or exterior support.

In addition, the inclined fixing groove allows fixing and maintaining the trim element without the use of tools, which is simpler.

In addition, the frame structure according to the invention makes it possible to maximize the possible covering surface by the covering element. Indeed, the inclined fixing groove being open towards the outside and oriented at an angle of 30° to 60°, makes it possible to increase the possible covering surface, for example in comparison with a groove perpendicular to the surface.

A display unit according to the invention can be formed from a single unit, or comprise a plurality of sub-units assembled together.

The outer longitudinal edge may further correspond to the outer peripheral edge of the frame structure.

The "face" of the frame structure means the surface of said structure, including the side edges of said structure.

The first face can correspond to a front face, or to a rear face of the frame structure.

Advantageously, a frame structure of a display unit according to the invention may comprise at least one fixing groove for a covering element on each of its front and rear faces.

Advantageously, at least one, in particular each, inclined fixing groove can be arranged on the side edge, at the level of the outer longitudinal edge of said side edge.

The outer longitudinal edge of a side edge corresponds to an edge of said side edge, if said side edge has a polygonal section, and in particular a rectangular section.

The frame structure according to the invention thus makes it possible to maximize the possible covering of the structure by a covering element, thus making it possible to cover the entire face to be covered.

Advantageously, at least one, in particular each, inclined fixing groove can be inclined, at least locally, in a direction forming an angle of 45° with respect to said first face.

The frame structure according to the invention thus makes it possible to have an optimum compromise between retention capacity of the trim element, accessibility and ease of use for fitting and removing the element. of dressing.

Advantageously, at least one, in particular each, inclined fixing groove can be at least partially formed by a removable bar fixed to the side edge.

In particular, the inclined groove can be formed jointly between a surface of the lateral edge and a bar fixed to said lateral edge.

The bar can be fixed by any usual means to the side edge of the frame structure, for example by means of screws.

The frame structure according to the invention thus makes it possible to have a modular inclined groove. This makes it possible, among other things, to be able to adapt the inclined fixing groove in order to best maintain a trim element, or to modify the type of fixing used.

This also makes it possible to facilitate the maintenance of the frame structure according to the invention.

Advantageously, at least one, in particular each, inclined fixing groove can be formed by a pair of removable bars fixed to said lateral edge, one facing the other.

Each bar can be fixed by any usual means to the side edge of the frame structure, for example using screws.

Alternatively one of the strips can be attached to the other, which itself is attached to the side edge.

The frame structure according to the invention thus makes it possible to have an even more flexible inclined groove. This makes it possible, among other things, to be able to adapt the inclined fixing groove in order to better maintain a trim element, for example by changing the angle of inclination of the groove, the width of the groove, but also the position of the groove.

Advantageously, at least one, in particular each, inclined fixing groove can be formed in a removable strip fixed to said lateral edge. Thus, it is possible to modify the inclined fixing groove as desired, simply and quickly.

Advantageously, the frame structure according to the invention may comprise at least two side edges each comprising at least one inclined fixing groove.

The frame structure of a display unit according to the invention thus makes it possible to have a better fixing of the covering element, while maximizing the surface covered by the covering element at the level of several lateral edges of the frame structure.

Advantageously, the frame structure according to the invention may comprise at least two adjacent side edges each comprising a angled fixing groove.

Advantageously, the frame structure according to the invention may comprise at least two opposite side edges each comprising a angled fixing groove.

According to a particular embodiment, the frame structure according to the invention may comprise at least one fixing groove which is not an inclined groove.

Alternatively, the frame structure according to the invention may comprise only one or more inclined fixing grooves.

Two fixing grooves provided on two side edges can have the same angle of inclination.

Alternatively, two fixing grooves provided on two side edges can have different angles of inclination.

Advantageously, at least one inclined fixing groove can be provided to receive a fixing joint integral, or not, with a trim element.

The inclined fixing groove can thus be dimensioned, for example in width/or in depth, to hold a trim element using a compressed joint between the walls of the groove.

Advantageously, at least one inclined fixing groove may comprise a first fixing means complementary to a second fixing means integral with a trim element.

• une bande adhésive de type velcro ;
• un ou plusieurs crochets ; ou
• un ou plusieurs aimants.

This first fixing means can for example be, or comprise:

• a Velcro-type adhesive strip;
• one or more brackets; Or
• one or more magnets.

• par assemblage, en particulier démontable, d’une pluralité de pièces telles que des montants, des profilés, etc. ; ou
• d’une seule pièce, par exemple par moulage ou impression 3D.

Advantageously, the frame structure according to the invention can be formed:

• by assembly, in particular removable, of a plurality of parts such as uprights, profiles, etc. ; Or
• in one piece, for example by molding or 3D printing.

The frame structure can be made of any hard material, such as metal, wood, aluminum, glass, hard plastic, etc.

• une structure de cadre ; et
• un élément d’habillage fixé à ladite structure de cadre grâce à au moins une rainure de fixation inclinée prévue sur ladite structure de cadre.

According to another aspect of the invention, there is proposed a display unit comprising:

• a framework structure; And
• a covering element fixed to said frame structure by means of at least one inclined fixing groove provided on said frame structure.

Advantageously, the covering element can be flexible.

The covering element can for example be a textile, a fabric or a tarpaulin.

Advantageously, the covering element can comprise at least one fixing means on at least part of its periphery.

This fastening means can for example be a seal or another fastening means such as an adhesive strip, a Velcro-type strip, one or more hooks, one or more magnets, etc.

Advantageously, the display unit may further comprise at least one display screen secured to said frame structure.

This display screen can be of any type, for example an LED screen.

This display screen may comprise a single tile, or a plurality of tiles, arranged side by side and working together to form a screen.

Advantageously, the display unit may further comprise a fixing support, secured to the frame structure, and on which the display screen is fixed.

In the figures, the elements common to several figures retain the same reference.

FIGURE 1 is a schematic and partial representation of a sectional view of an example of the side edge of a frame structure of a display unit according to the invention.

FIGURE 1 illustrates, in a sectional view, part of a side edge 100 of a frame structure according to the invention.

• une face d’habillage 102, destinée à être au moins en partie recouverte par un élément d’habillage, et qui fait partie d’une première face de la structure de cadre qui sera recouverte par l’élément d’habillage ;
• une bordure périphérique longitudinale extérieure 104, qui forme aussi une bordure périphérique de la structure de cadre ;
• une bordure périphérique longitudinale intérieure 105, qui se trouve du côté opposé à la bordure longitudinale extérieure 104, et qui se trouve du côté intérieure de la structure de cadre.

Side edge 100 includes:

• a covering face 102, intended to be at least partly covered by a covering element, and which forms part of a first face of the frame structure which will be covered by the covering element;
• an outer longitudinal peripheral edge 104, which also forms a peripheral edge of the frame structure;
• an inner longitudinal peripheral border 105, which is on the opposite side to the outer longitudinal border 104, and which is on the inner side of the frame structure.

In the example shown, the side edge is formed by a piece of rectangular section. Thus, the outer longitudinal border 104 corresponds to a face of the part located on the outer side of the frame structure and the inner longitudinal border 105 corresponds to a face of the part which is located inside the frame structure.

The side edge 100 further comprises a fixing groove 106 of a trim element.

This groove is inclined at an angle of 45° with respect to the covering face 102 and open in the direction of the outer longitudinal edge 104 of the lateral edge 100.

The first face, intended to be covered by a covering element, preferably corresponds to a front face, or to a rear face, of a frame structure of a display unit.

As part of the example shown, the inclined fixing groove 106 is open on an edge of the side edge 100, which here corresponds to the intersection of the covering face 102 with the peripheral face 104.

The fixing groove 106 comprises a first surface 108, located on the side of the covering face 102, as well as a second surface 110, facing said first surface 108.

FIGURE 2 is a schematic and partial representation of a sectional view of another example of a side edge of a frame structure of a display unit according to the invention.

FIGURE 2 illustrates, in a sectional view, part of a side edge 200 of a frame structure according to the invention.

The frame edge 200 differs from the frame edge 100, illustrated in FIGURE 1, in that it includes a removable strip 202.

The removable bar 202 is fixed to the side edge 200 by any usual means (not shown in FIGURE 2).

The removable bar 202 at least partially forms the groove 106. In the example of FIGURE 2, the removable bar 202 comprises the first surface 108 and jointly forms the fixing groove 106 with the second surface 110.

FIGURE 3 is a schematic and partial representation of a sectional view of another example of a side edge of a frame structure of a display unit according to the invention.

FIGURE 3 illustrates in a sectional view, part of a side edge 300 of a frame structure according to the invention.

The side edge 300 differs from the side edge 200, illustrated in FIGURE 2, in that it includes a second removable strip 302.

The two removable strips 202 and 302 are fixed to the side edge 300 by any usual means (not shown in FIGURE 3).

Alternatively, one of the two strips can be attached to the other, the latter being attached to the side edge.

In the example of FIGURE 3, the two bars 202 and 302 come together to form the fixing groove 106. The removable bar 202 thus comes to form the first surface 108 of the fixing groove 106. The second surface 110 of the groove of attachment 106 is formed by the second strip 302.

FIGURE 4 is a schematic and partial representation of a sectional view of another example of a side edge of a frame structure of a display unit according to the invention.

Side edge 400, shown in FIGURE 4, differs from frame edge 300, shown in FIGURE 3, in that it includes a single removable bar 402 including groove 106.

This removable bar 402, comprising the groove 106, can be fixed to the side edge 400 by any usual means (not shown in FIGURE 4).

In the examples illustrated in FIGURES 1-4, the fixing groove 106 is inclined at 45 degrees with respect to the covering face 102. It is however possible, according to variant embodiments, to have a fixing groove 106 inclined at an angle between 30 and 60 degrees.

In the examples illustrated in FIGURES 1-4, the fixing groove 106 can be provided to receive a fixing joint integral, or not, with a trim element.

Also in the examples illustrated in FIGURES 1-4, the fixing groove 106 is disposed at a peripheral edge of the frame. In other words, the opening of the groove 106 is arranged at the level of the edge between the covering face 102 and the edge face 104. It is however possible, according to variant embodiments, to have a fixing groove 106 the opening of which is arranged at another location of the covering face 102.

In the example of FIGURES 2 to 4, the bar or bars 202, 302 and 402 are embedded in the side edges 200, 300 and 400. Alternatively, it would be possible, according to variant embodiments, to obtain a fixing groove 106 by fixing the bar(s) 202, 302 and 402 on the cover surface 102, so that said bar protrudes from the cover face of the side edge.

In the example of FIGURES 2 to 4, it is also possible to dismantle and therefore change the strips 202, 302 and 402. It is thus possible with these embodiments to change the characteristics of the fixing groove 106. These modes of embodiments thus make it possible to adapt the groove to the need for fixing a trim element. It is for example possible to adapt the spacing between the faces 108 and 110 of the fixing groove 106 to adapt the groove to joints having different dimensions. It is also possible to adapt the fastening means by installing bars comprising other fastening means such as, for example, a Velcro-type adhesive strip, one or more hooks or one or more magnets. It is also possible for the embodiments of FIGURES 3 and 4 to change the angle of inclination of the groove 106, as well as the depth of the groove.

In the examples illustrated in FIGURES 1-4, the side edges of frames 100, 200, 300 and 400 have a section whose shape is preferably rectangular. It is however possible, according to variant embodiments, to have frame edges having a section whose shape is polygonal or circular.

FIGURE 5 is a schematic and partial cross-sectional view of two side-by-side frame structures, each covered by a trim member.

FIGURE 5 illustrates, in a cross-sectional view, two side edges 100₁ and 100₂of frame structure side by side. Each side edge 100₁ and 100₂includes a covering surface, respectively 102₁and 102₂, and a fixing groove, respectively 106₁and 106₂, of a skin element. Trim elements 502₁ and 502₂are respectively inserted into the grooves 106₁ and 106₂. Trim elements 502₁ and 502₂are respectively held in place in the grooves 106₁ and 106₂by seals 504₁ and 504₂compressed into the grooves. Seals 504₁ and 504₂may or may not be independent of trim elements 502₁ and 502₂.

Each frame structure covered by a trim element forms a display unit.

It is important to note that each trim element 502₁ and 502₂of a display unit completely covers one side of the frame structure of said display unit.

Additionally, it is important to note that for ease of illustration there is a blank space between the trim elements 502₁ and 502₂and faces 102₁ and 102₂they cover, it is however possible that the trim elements 502₁ and 502₂are in contact with the faces 102₁ and 102₂.

FIGURE 6 is a schematic representation of an example of a frame structure of a display unit according to the invention.

FIGURE 6 illustrates, in a front view, a rectangular frame structure 600. This frame structure 600 includes four side edges, also called uprights or sides.

The frame structure 600 includes two horizontal uprights 602₁ and 602₂, and two vertical uprights 100₁and 100₂, each of which may be identical to the side edge 100, 200, 300 and 400 of FIGURES 1-4. Each vertical upright 100₁and 100₂comprises a longitudinal fixing groove, respectively 106₁and 106₂.

The example frame structure of FIGURE 6 thus comprises two opposite sides or uprights each comprising a fixing groove 106. This allows a good fixing of a covering element on the structure 600.

Alternatively to the example of FIGURE 6, it is possible to have a frame structure comprising two adjacent sides each comprising a fixing groove 106.

FIGURE 7 is a schematic representation of another example of a frame structure of a display unit according to the invention.

Frame structure 700, shown in FIGURE 7, is rectangular.

The frame structure 700 comprises four upright or side 100 ₁ -100 ₄ , each of which can be identical to the side edge 100, 200, 300 and 400 of FIGURES 1-4.

Each upright, or side, 100 ₁ -100 ₄ comprises a longitudinal fixing groove, respectively 106 ₁ -106 ₄ .

This allows optimum retention of a trim element on the 700 frame structure.

Alternatively to the examples of FIGURES 6 and 7 it is possible to have a frame structure having a shape other than rectangular, for example of polygonal or circular shape.

FIGURE 8 is a schematic representation of an example of a display unit according to the invention.

Display unit 800 of FIGURE 8 includes a rectangular frame structure 802, which may be identical to frame structures 600 and 700 of FIGURES 6 and 7.

The display unit 800 further comprises a covering element 802 covering the front face 804 of the display unit. The trim element 806 is inserted and held in fixing grooves provided on the frame structure.

It is important to note that for clarity of illustration a space is visible is left between the trim member 806 and the outer edge of the frame structure 802. It is obvious from the description that the opening of the fixing grooves can be positioned at the level of the outer edge of the frame structure 802. In this case, the trim element 806 comes to cover the entire front face 804 of the display unit 800.

Of course, the invention is not limited to the examples detailed above. It is also possible for those skilled in the art to come and combine the different embodiments detailed above.
