Description

 The invention relates to a display panel and to posters specially intended for such a panel.

 There are already known type display panels comprising a support frame; a box-shaped casing carried by the support frame, having at least one window on at least one of its two large faces, and containing support means for at least one poster, arranged so that one or more posters can be visible through the window or windows which are parallel and close thereto, the poster support means comprising a pair of positive poster holding means along its two vertical lateral edges.

 Reference may be made, for example, to document FR-A-2,743,181.

 According to this document, the panel also comprises means for translational drive of the poster support means so as to ensure the continuous scrolling or not of the posters. This scrolling is horizontal.

We can also refer to the documents
FR-A-2 610 439, US-A-5 018 289 and US-A-5 138 781.

 One of the major problems which arises in display panels of the type previously considered is that of fixing the posters.

 This problem is all the more crucial as the posters are intended to be displayed.

 And that, moreover, their attachment must be removable.

 This problem of attachment is all the more important that the posters are of large dimensions, that the display panel, therefore the posters, must be able to face variable climatic conditions, in particular of temperature and hygrometry and, finally, that a high degree of quality is desired for the presentation of the posters.

 In order to achieve these objectives, the invention provides a display panel of the type considered above in which at least one positive poster holding means comprises, at least on part of the associated vertical lateral border, a support piece poster having a first profile adapted to be nested by complementarity of shape, transversely to the associated lateral border, with a second profile of a connecting piece to the vertical lateral border of the poster.

 The invention relates to a display panel 1 intended to receive posters such as 2.

 The panel 1 comprises a support frame 3 including a base 4, carrying a casing 5, of generally parallelepiped shape.

 The housing 5 has a general box shape. It comprises firstly a belt 6 forming the edge of the casing 5 and, on either side, two large faces 7.

 One of (or both) large faces 7 has a window 8 provided with a protective glass.

 Such a display panel 1 is intended to be placed with its vertical base 4 and the main plane of the casing 5, the large faces 7 and the windows 8 of which are parallel, vertical. This plan is referenced P.

 The belt 6 has, for its part, a main axis passing through the large faces 7, arranged horizontally, perpendicular to the plane P.

 For reasons of convenience, the description is made with reference to a display panel 1 erected as just described.

 It is with reference to this situation that qualifiers such as "horizontal" or "vertical" must be understood.

 Furthermore, the display panel 1 is considered with respect to an observer placed opposite the window 8, or one of the windows 8 in the case where the panel 1 comprises two.

 The qualifiers "front", "rear", "frontal", etc. refer to this situation.

 However, it is understood that during its storage or for its assembly or even for its transport, the display panel 1 or its constituent elements can be placed or arranged in a position other than that mentioned previously.

 The display panel 1 also includes means 9 for poster support 2.

 These means 9 are arranged so that the posters 2 are arranged vertically opposite the window 8, just behind it.

 The posters 2 placed on the display panel 1 are, in the embodiment considered, of square or rectangular outline, limited by an upper horizontal border 10, a lower horizontal border 11 and two lateral, vertical borders 12.

 By border is meant here the area of poster 2 adjacent to its free outer edge.

 A poster 2 thus comprises a main printed part 13, made of polymer or laminated paper, therefore having a certain flexibility and capable of being deformed and more particularly rolled, wound or placed. Along three of its four free edges, the part 13 is provided with a strip, overlapping on the part 13 and secured to it, in particular by gluing.

 In the example shown, the part 13 is provided on its edge 10 with a horizontal strip 14a and on each of its lateral edges 12, with a lateral strip 14b.

 One or more strips 14a, 14b is produced according to the embodiment considered here in a flexible but inextensible plastic material and having a high resistance.

 The strip 14a is provided with eyelets 15 regularly arranged along its length.

 The three bands 14a, 14b formed on the part 13 to form the borders 10, 11, 12 allow the support of the poster 2 taken as a whole (that is to say its useful printed part 13).

 In the embodiment considered, there are provided several posters 2 placed one beside the other, horizontally, but independent of each other. These posters 2 are all supported by the support means 9.

 In this case, a poster 2 is located opposite window 8 while the other posters 2 are hidden from view with respect to this window 8. In this embodiment, the panel 1 therefore also includes drive means 16 for support means 9 so as to ensure the scrolling of the posters 2.

 This scrolling is preferably discontinuous, that is to say that the drive means 16 are stopped for a certain time when the poster 2 facing the window 8 can be seen by the observers. Then, the drive means 16 are active to change the poster and so on.

 However, also falls within the scope of the invention the case where the posters 2 scroll continuously, the drive means 16 being arranged accordingly.

 In the embodiment considered, the scrolling of the posters is horizontal.

 However, also falls within the scope of the invention the case where the scrolling is vertical.

 Finally, the invention also relates to the case where the panel 1 is intended for a single poster, fixed or mobile.

 The support means 9 comprise in combination first means 9a and a pair of second means 9b.

 The first means 9a maintain the poster 2 along its upper horizontal edge, that is to say at the location of the upper horizontal edge 10.

 The second means 9b maintain the poster 2 along its two vertical edges, that is to say at the location of the vertical lateral edges 12.

 The support means 9 do not include means for holding the poster 2 along its lower horizontal edge. For this reason, poster 2 is not intended to have a lower strip.

 The support means 9, 9a, 9b will now be more specifically described, in the case where a plurality of posters 2 are provided, juxtaposed horizontally but independent of one another, driven in horizontal movement by means of the drive means 16 arranged for this purpose.

 The support means 9, 9a, 9b are arranged so that the poster 2 can be maintained without risk of untimely stalling, the support being nevertheless removable, when desired.

 The first means 9a will now be described more specifically.

 These first means 9a firstly comprise a support member 17, extended horizontally parallel to the posters 2, namely their border 10.

 This support member 17 is flexible and inextensible.

It is in the form of an endless chain or equivalent and is also part of the drive means 16.

 The endless chain 17 is slidably mounted in a guide member 18 and it is engaged with toothed pinions 19 mounted wedged on the axis 20 of guide rollers, deflection and return of the posters 2.

 The pinions 19 are placed towards the upper free end part of the axes 20.

 The axes 20 are arranged vertically.

 In the embodiment under consideration, three pairs of rollers 21 are provided, namely a pair of front rollers 21a, a pair of rear rollers 21b, and a pair of middle rollers 21c.

 The front rollers 21a are located near the window 8.

 The rear rollers 21b are located near the large face 7 opposite the window 8 considered.

 As for the median rollers 21c, they are located in the vertical median plane of the panel 1.

 The front rollers 21a and the rear rollers 21b are spaced apart from each other and located near the vertical walls 6a of the belt 6.

 The median rollers 21c are on the contrary spaced from these vertical walls 6a and close to the horizontal axis of the belt 6.

 In the case where the panel 1 has two windows 8 on either side, the arrangement is symmetrical.

 One of the rollers 21 comprises, wedged on its axis, a motor or geared motor belonging to the drive means 16. In addition, one of the rollers, in particular of the pair of median rollers 21c is mounted movable horizontally parallel to the plane P so as to accommodate differences in length or tension of posters 2.

 The guide member 18 is arranged and arranged in several sections between the different rollers 21.

 This guide member 18 is, in the embodiment more particularly shown in the drawing, in the form of a profile 22 in the general shape of a U, in which is mounted a plastic part comprising a guide cavity of the chain 17 sliding, with minimal friction.

 The profile 22 is fixed to the frame 3 by screwing, riveting or in any other appropriate equivalent manner.

 The first support means 9a then comprise a series of rigid legs 23 fixed rigidly and transversely to the chain 17. These legs 23 are regularly spaced from one another. They are directed downwards.

 Those of the legs 23 which are situated opposite the window 8 are arranged in a coplanar manner and form a support plane 24 for the corresponding poster 2, namely for its border 10.

 A lug 23 comprises a part 25 of generally rectangular shape, provided towards the rear with a recess 26 whose shape is complementary to that of a rigid, bent part 27, fixed to a pin 28 of a chain link 17.

 The two parts 25 and 27 are fixed to each other by means of a fixing member such as a screw, a rivet or the like.

 The support plane 24 is formed by the front face of the part 25. This support plane 24 and this front face happen to be coplanar with the axis of the pin 28.

 This arrangement avoids undesired unwanted voltages on the first means 9a, which is important insofar as these also participate in the training of the poster 2.

 At least a portion of the legs 23 is provided frontally with studs 30, arranged transversely, frontally.

 These studs 30 project from the front face defining the plane 24.

 These studs 30 are intended to pass through the eyelets 15 formed on and in the upper horizontal border 10.

 The relative dimensions of the eyelets 15 and the studs 30 are such that their cooperation is made possible to allow the removability of the poster 2 but to prevent its untimely detachment.

 To this end, provision is made in the embodiment under consideration for a stud 30 to include a narrowed rear base 31 forming a groove and, adjoining the latter, a bulged part 32.

 Where appropriate, the front free end portion of the stud 30 opposite the base 31 forms a point 33.

 The groove formed by the narrowed base 31 is relatively slightly open so that the edge 10 can be accommodated therein in its thickness, at the periphery of the eyelets 15 by being adjusted.

 However, the opening of the groove is sufficiently open - for example of the order of ten to fifty times the thickness of the strip 14 - so that the cooperation of the strip 14 and the groove is not made impossible and that the groove can absorb variations in the flatness of the strip 14.

 Where appropriate, the groove has in cross section a profile which is broadly open towards its opening to facilitate installation and removal.

 The strip 14 having a certain flexibility can be forced into a stud 30 by virtue of the presence of the tip 33 and then come to be housed in the groove formed by the narrowed base 31.

 The legs 23 provided with the studs 30 form a first group. The legs 23 devoid of studs 30 form a second group. The pads 30 are spaced from each other, the tabs 23 do not interfere with each other. It is intended, for example, that one in three tabs is provided with a stud 30 and two in three does not. The legs 23 of the second group play the function of support plane 24 but not of positive support of the poster 2.

 The guide member 18 is interrupted near and opposite a pinion 19.

 A roller 21 has a slightly deformable outer wall, for example made of plastic foam. This structure makes it possible to absorb the differences in tension exerted by a poster along a roll 21. In fact, such differences in tension are inevitable due to the size of the posters, dimensional tolerances, and operating conditions (in particular ).

 The rollers 21 also have a hollow part below the pinions 19 forming a reserve so as to allow the chain 17 to pass.

 The structure considered is such that the support plane 24 of the legs 23 is tangent or substantially tangent to the peripheral support surface of the rollers 21.

The presentation of the posters 2 is thereby improved and the voltage differences attenuated, if not eliminated.

 The poster support means 9 comprise a pair of positive poster holding means along two parallel and opposite edges of the poster, hereinafter called associated edges.

 In the embodiment shown, the pair of positive poster holding means is provided along the two vertical lateral edges 12 of the poster 2.

 This pair of positive poster holding means is therefore included in the means 9b.

 In other embodiments, not shown, the pair of positive poster holding means is provided along two upper horizontal 10 and lower 11 lateral edges 11 of the poster 2.

 The pair of positive poster holding means is then included in the means 9a.

 At least one positive poster holding means comprises a poster support piece 34 having a first profile 36 capable of being fitted by complementary shape, transversely to the associated border, in a second profile 37 of a piece 35 of link to the border of the poster.

 In what follows, by transverse is meant a direction situated in a plane perpendicular to the direction in which the associated border extends.

 The profiles extend parallel to the associated border.

 These support and connection parts 34, 35 make it possible to quickly and removably mount and dismount one or more posters in the panel.

 The poster support piece 34 is fixed to the chain 17, respectively to the lug 23 in any suitable manner. For example, by machining or riveting.

 The support piece 34 extends, from the upper border 10 downwards, along at least part of the lateral border 12 of the poster 2.

 In one embodiment, the support piece 34 extends along the entire edge 12.

The connecting piece 35 is fixed to the vertical lateral border 12 of the poster by any suitable means, for example by gluing (double-sided adhesive, etc.)
The connecting piece 35 extends over the edge of the poster, corresponding to the support piece 34.

 In particular, in an embodiment, not shown, the support piece 34 and the connecting piece 35 extend, from the upper edge 10, over a first part of the lateral edge 12, for example over the upper half of this one.

 In another embodiment, which is not shown either, the parts 34, 35 further extend over a second part of the border 12 separated from the first part, for example in the lower quarter of the border 12.

 Profile 36 has at least one female part 38 and profile 37 has at least one associated male part 39.

 In the embodiment shown, the profiles 36, 37 each comprise two male parts and two associated female parts.

 In one embodiment, not shown, the profile 36 comprises a single male part and / or a single female part and the profile 37 comprises a single associated female part and / or a single associated male part.

 In other embodiments, not shown, the profile 36 has more than two male parts and more than two female parts. Profile 37 has a corresponding number of associated female parts and a corresponding number of associated male parts.

 Each male part is of complementary shape to the associated female part and is intended to be fitted into the latter in a fitting direction E, transverse to the associated border 12.

 The nesting direction E cuts the plan of the poster. The direction E is for example normal to the plane of the poster.

 In the embodiment shown, the male parts of the same profile are of the same shape and the female parts of the same profile are of the same shape.

 In other embodiments, not shown, the male parts are of different shape and / or the female parts are of different shape.

 In what follows, the description is made with reference to the male part 39 and to the associated female part 38 as shown.

 The male part 37 is in the general shape of a dovetail.

The male part 37 comprises a base 40 extending substantially perpendicular to the direction E of interlocking. A foot 41 projects in the direction
E of nesting, of base 40.

 The foot 41 is attached to a head 42, of thickness, in a direction transverse to the associated border 12, greater than that of the foot 41. This transverse direction intersects and, in the embodiment shown, substantially perpendicular to the direction E d 'nesting.

The female part 38 is substantially in the form of
U, comprising a first central branch 43 and, connected thereto on its first and second end portions, first and second lateral branches 44, 45.

 The central branch 43 extends substantially perpendicular to the direction E of nesting. While the side marks are directed in the same direction in direction E.

 The second lateral branch 45 comprises, spaced from the central branch 43, a spout 46 directed towards the first central and lateral branches 43, 44.

 The first lateral branch 44 is bent towards the second lateral branch 45 on its part remote from the central branch 43.

 In the embodiment shown, the first and second profiles 36, 38 are of complementary and identical shapes which facilitates their manufacture. The lateral branches 44, 45 act as male parts.

 Thus, the female parts of the same profile are delimited by two male parts side by side.

 At least one male part of the first or second profile 36, 37 has an end part directed respectively in a transverse direction in a direction moving away or approaching the poster 2.

 The spout 46 of the female part 38 of the first profile 36 is directed in a transverse direction in a direction away from the associated edge 12 of the poster 2.

 The head 42 has an end portion 42a, depending on its thickness, directed towards the poster 2.

 In the embodiment shown, this part 42a has substantially the same shape as the spout 46.

 The part 42a and the spout 46 are directed substantially at 45C with respect to the direction E of interlocking.

 The profiles 36, 37 are such that when they are fitted together, the support part 34 is immobilized with respect to the connecting part 35, transversely to the associated border 12.

 When the profiles 36, 37 are fitted one into the other, the spout 46 and the part 42a are head to tail.

 In other embodiments, not shown, the male part or parts are in the form of a lobe, the associated female part or parts being of complementary shape.

 The parts 34, 35 are made of a material such that the profiles 36, 37 do not slide relative to each other along the associated edge, when they are fitted.

 In the embodiment under consideration, the poster support part 34 comprises at least one strip 47 of flexible plastic material having a part 47a profiled according to the first profile 36.

 The connecting piece 35 comprises at least one strip 48 of flexible plastic material having a part 48a profiled according to the second profile 37.

 A first profile 36 is provided along an edge of the strip 47 facing the associated border 12 of the poster.

 The strip 47 has a part 47b, free of profile 36.

 A second profile 37 is provided along an edge of the strip 48 furthest from the center of the poster 2.

 The strip 48 has a part 48b, free of profile 37.

 To support two parallel and adjacent edges of two posters, the means 9b comprise at least a first and a second support piece 34a and 34b side by side, respectively comprising a first and a second strip 47c, 47d of profiled plastic material, for respectively first and second posters. The parts 34a and 34b are profiled according to symmetrical profiles as in a mirror, for example.

 In one embodiment, not shown, the first and second support parts are combined in a single one, for example in a single strip of plastic material.

 In the embodiment shown, the first and second parts 34a, 34b are interconnected by a band 49 of concealment.

 The occultation strip 49 comprises a strip of flexible fabric, opaque and fixed by any suitable means on the first and second profiled plastic strips of the parts 34a, 34b, at a distance from the first profiles 36, on the parts 47b.

 In the embodiment shown, the masking strip 49 is sewn on the first and second strips, along two lines 50 and 51 and / or heat-welded on the parts 47b.

 The strip 49 is for example extensible.

 These lines 50 and 51 are for example rectilinear and parallel to the associated borders 12.

 This occultation strip 49 is particularly useful when the display panel 1 has interior lighting allowing the viewing of the posters 2 by transparency.

 Thanks to the strip 49, the light between the two posters and between the two adjacent support pieces 34 is obscured.

 Means are provided for mounting the connecting piece 35 on the support piece 34 and means for dismantling it.

 These means are provided on or in the panel and / or on the border of the poster and / or are separate.

 In the embodiment shown, these means comprise a slider 52, capable of fitting and disengaging the first and second profiles 36, 37.

 The cursor 52 has a general form of slide for the closure formed by the first and second profiles 36, 37.

 The cursor 52 is described as a separate part in FIGS. 11 to 14 with reference to an orthonormal reference frame XYZ.

 The direction X represents the direction parallel to the associated border 12 of the poster, when the first and second profiles 36, 37 are nested.

 The cursor 52 includes a guide 53 of first profile and a guide 54 of second profile.

 Guide 53 extends in direction X.

 The guide 54 extends parallel to a direction of the plane XZ, rectilinear with respect to the direction X.

 In the embodiment shown, this inclination is between 10 and 60C and is for example substantially equal to 300.

 In other embodiments, not shown, this inclination is less than 100 or greater than 60 ".

 Guide 53 and guide 54 have, transversely to their direction of extension, a generally rectangular profile.

 In other embodiments, not shown, this profile is of polygonal shape other than rectangular, for example pentagonal or hexagonal, or of rounded shape, for example elliptical, circular or ovoid.

 The guide 53 and the guide 54 are connected together by a middle plate 55.

 The plate 55 forms the lower part of the guide 54 and the upper part of the guide 53.

 The internal dimensions of the guides 53 and 54 are adapted for the passage, in their respective direction of extension, of the first and second profiles 36, 37.

 The profile 53 comprises a lower plate 56, opposite the middle plate 55 and connected to the latter by a side plate 57, parallel to the plane XZ.

 The guide 54 comprises an upper plate 58 opposite the central plate 55 and connected to the latter by a side plate 59, parallel to the plane XZ.

 The plates 57 and 59 are connected to opposite end portions of the central plate 55.

 The guide 53 has a lateral flange 60, parallel to the plane XZ, and connected to the plate 53 on an end part thereof remote from the end part by which it is connected to the plate 57.

 The guide 54 has a lateral flange 61, parallel to the plane XZ and connected to the plate 54 on an end part thereof which is opposite to that by which the plate 54 is connected to the plate 59.

 The flanges 60 and 61 are oriented towards the middle plate 55 by providing a slot, respectively 62, 63 with the middle plate 55.

 These slots 62, 63 are intended for the passage of parts 47b, 48b, free of profiles, of strips 47, 48.

 In the following, the terms "front", "front" and "rear" are taken with reference to the direction X.

 The cursor 52 presents, seen frontally, a general shape of S.

 The median plate 55 has, seen from the side in the direction Y, an external shape of a parallelogram.

 The plate 55 has a first outer side 55a before, turned upwards and parallel to the plane XY.

 The plate 55 also has a second outer side 55b, opposite the side 55a, and facing the plate 53.

 The sides 55a and 55b are connected to each other, on the one hand by a third external side 55c and by a fourth external side 55d.

The sides 55c and 55d are parallel to the direction
Y and inclined parallel to the direction of extension of the second guide 54.

 The side 55c is turned towards the plate 54.

 The cursor 52 has no part facing the side 55a and 55d.

 The cursor 52 is provided with gripping means.

 In the embodiment shown, these gripping means comprise a ring 64, passing through a loop 65 closed on the upper plate 54.

 The loop 65 is of substantially rectangular shape, with rounded corners, and parallel to the plane XZ.

 In other embodiments, not shown, the gripping means comprise, instead of a ring, a handle of any suitable shape, for example, rectangular, planar, and where the loops are of another shape, for example polygonal or circular.

 The gripping means are connected by any suitable means to the cursor.

 The plate 55 has a protruding front edge 55e frontally connecting the sides 55a and 55d and frontally connecting the plates 57 and 59.

 The plate 55 also has a rear edge 55f connecting the sides 55c and 55b to the rear and connecting the plates 57 and 59 to the rear.

The edges 55e and 55f are parallel to the direction
Y. The edge 55f is located between the front part and the rear part of the plates 53 and 54.

 The plates 53 and 54 are therefore directly vis-à-vis by their rear parts, providing an opening narrowing from the front to the rear.

 The cursor 52 has a curved exterior shape.

 In the embodiment shown, the plates 59, 57 and the flanges 60, 61 are curved outwards.

 The interlocking of the first and second profiles 36, 37 is carried out by frontal introduction of the profiles 36, 37 respectively in the guides 53, 54 according to the respective direction of extension thereof, or by advancing the cursor 52 around the profiles 36 , 37 in reverse.

 The dimensions of the rear opening of the cursor are such that the first and second profiles are fitted into one another when they pass there from front to rear or when the cursor 52 is advanced towards the front. .

 For the interlocking of the nested profiles 36, 37, these are introduced into the rear opening of the cursor from the rear to the front where the cursor 52 is moved back with its rear opening 66 surrounding the profiles 36, 37.

 The separation of the profiles 36, 37 from one another is effected by the latter against the edge 55f or by abutment of the edge 55f against them, the profiles 56, 57 then being guided in the guides 53, 54, coming out separately in the front part of these.

 The vertical border 12 of the poster is fixed in the panel 1 by sliding in one direction, for example from top to bottom, of the cursor 52 around the profiles 36, 37 of the parts 34, 35.

 The vertical border 12 of the poster 2 is separated by sliding in one direction, for example from bottom to top, of the cursor 52 around the profiles 36, 37 of the pieces 34, 35.

 The attachment of the part 34a to the associated connecting part 35 is effected by sliding in the opposite direction from that by which the part 34b is fixed to the associated connecting part 35, in the example where these parts 34a and 34b are profiled following symmetrical profiles as in a mirror.

 In this case, it is also the same for dismantling the poster, in reverse.

 The cursor 52 is metallic, for example in chromed steel.
