Description

[0001] The present invention relates to an electronic label holder device.

[0002] In the state of the art, electronic label holder devices are known comprising a back wall that mounts two tab portions that have elastic portions adapted to bend very slightly, meaning that they cannot engage electronic labels of different sizes. A space between the tabs is adapted to hold only one type of electronic label of a certain size. If another type of larger electronic label is to be held, it is necessary to use another larger-sized holder device that allows more space to embrace and hold the larger electronic label.

[0003] Disadvantageously, there are no universal injection-moulded holder devices that can engage electronic labels of different sizes.

[0004] US 2023 / 0394995 A1 and EP 2166529 A1 describe an electronic label holder made by extrusion, thus rear coupling portions need to be as long as a section bar width.

[0005] IT 2021 000013703, the Italian priority of CN217181552U, describes two distinct parts: an adapter device for electronic labels and a holder device with a longitudinal section bar made by extrusion that in turn supports said adapter device, where in practice two parts are required to mount the electronic label and to mount the adapter device to a display element.

[0006] The object of the present invention is to provide a holder device for electronic labels that is universal, that is most easily made as one piece, that can hold electronic labels of a multiplicity of different sizes, that can be coupled in a versatile manner to a multiplicity of display elements of different shapes and widths, and that overcomes the disadvantages of holder devices of the prior art.

[0007] According to the invention, this object is achieved with a holder device for an electronic label according to claim 1.

[0010] With reference to the above-mentioned figures and in particular Figures 5, 6 and 7, a holder device 10 for an electronic label 100 comprising a section bar 11 is shown.

[0011] The section bar 11 comprises a back wall 12 extending longitudinally.

[0012] The section bar 11 comprises an upper tab 21 extending from an upper end 121 of said back wall 12.

[0013] The section bar 11 comprises a lower tab 22 extending from a lower end 122 of said back wall 12.

[0014] The section bar 11 comprises a space defined between said upper tab 21 and said lower tab 22 adapted to allow the insertion of at least a portion of said electronic label 100.

[0015] Said space is also referred to as the space for the insertion of said at least a portion of said electronic label 100.

[0016] Said upper tab 21 comprises an upper curvilinear wall 23 extending from said upper end 121 of said back wall 12. Said upper curvilinear wall 23 makes the upper tab 21 elastic.

[0017] Said upper tab 21 comprises an upper transverse wall 25 extending from one end of said upper curvilinear wall 23.

[0018] Said upper tab 21 comprises an upper retaining element 27 rising from the upper transverse wall 25 towards said space for the insertion of said at least a portion of said electronic label 100.

[0019] Said upper retaining element 27 is adapted to engage at least an upper retaining element of said at least a portion of said electronic label 100.

[0020] Said upper tab 21 comprising said upper curvilinear wall 23 is elastic in that it is adapted to switch from a resting configuration to an increased bending configuration.

[0021] Preferably said resting configuration of said upper tab 21 provides that said upper transverse wall 25 forms a first angle α with said back wall 12, wherein said first angle α is between 70 and 110 sexagesimal degrees, preferably between 75 and 95 degrees, even more preferably 79 sexagesimal degrees.

[0022] Preferably said increased bending configuration of said upper tab 21 provides that said upper transverse wall 25 forms a second angle β with said back wall 12, wherein said second angle β is between 100 and 140 sexagesimal degrees, preferably between 110 and 130 sexagesimal degrees, even more preferably 123 sexagesimal degrees.

[0023] Said lower tab 22 comprises a curved lower wall 24 extending from said lower end 122 of said back wall 12.

[0024] Said lower curvilinear wall 24 makes the lower tab 22 elastic.

[0025] Said lower tab 22 comprises a lower transverse wall 26 that extends from one end of said lower curvilinear wall 24.

[0026] Said lower tab 22 comprises a lower retaining element 28 rising from said lower transverse wall 26 towards said space for the insertion of said at least one portion of said electronic label 100.

[0027] Said lower retaining element 28 is adapted to engage at least one lower retaining element of said at least one portion of said electronic label 100.

[0028] The two retaining elements 27 and 28 hold and support the electronic label 100 mounted in the space for inserting at least one portion of the electronic label.

[0029] Said lower tab 22 comprising said lower curvilinear part 24 is elastic in that it is adapted to switch from a resting configuration to an increased bending configuration.

[0030] Preferably said resting configuration of said lower tab provides that said lower transverse wall 26 forms a third angle γ with said back wall 12, wherein said third angle γ is between 45 and 80 sexagesimal degrees, preferably between 50 and 60 sexagesimal degrees, even more preferably 54 sexagesimal degrees.

[0031] Preferably, said increased bending configuration of said lower tab 22 provides that said lower transverse wall 26 forms a fourth angle δ with said back wall 12, wherein said fourth angle δ is between 75 and 120 sexagesimal degrees, preferably between 95 and 110 sexagesimal degrees, even more preferably 105 sexagesimal degrees.

[0032] The resting configurations are shown by the solid lines in particular in Figure 5, while the increased bending configurations are shown by the dashed lines in particular in Figure 5.

[0033] The maximum opening of the space between the tabs 21 and 22 can reach a value comprised between 30 and 40 mm, even more preferably up to 34 mm.

[0034] Preferably, the distance between a tip of the upper retaining element 27 and the lower retaining element 28 is between 23 mm and 34 mm, wherein 23 mm represents a measurement when the opening of the space between the tabs 21 and 22 is minimum and 34 mm represents the maximum opening of the space between the tabs 21 and 22.

[0035] During injection moulding, the holder device 10 may undergo slight variations, i.e. the upper 21 or lower 22 tabs may vary by a few sexagesimal degrees with respect to the value stated the above.

[0036] Preferably, as shown in the figures, said upper transverse wall 25 and said lower transverse wall 26 extend in a rectilinear manner.

[0037] Alternatively, at least one of the two transverse walls 25, 26 extends in a rectilinear manner.

[0038] Still alternatively, at least one of the two transverse walls 25, 26 extends following a curve, wherein the curve is comprised between the geometric figures of a geometric conic section, i.e. for example an arc of a circle, a portion of an ellipse, a portion of a parabola, a portion of a hyperbola.

[0039] Preferably said upper curvilinear wall 23 traces an arc of a circle of at least one quarter circumference and comprises a concave portion facing said space for the insertion of said at least one portion of said electronic label 100.

[0040] Alternatively, it is possible to provide for the upper 23 and / or lower 24 curvilinear wall to trace a geometric conic section.

[0041] Alternatively, it is provided that said upper curvilinear wall 23 traces a portion of a geometric conic section, i.e. for example a quarter of an arc of a circle, a quarter of a portion of an ellipse, a portion of a parabola, a portion of a hyperbola.

[0042] Advantageously, the fact that the upper curvilinear wall 23 traces an arc of a circle of this size makes it possible to achieve increased bending and accommodate different electronic labels of different sizes.

[0043] Even more preferably said lower curvilinear wall 24 traces an arc of a circle of at least one quarter circumference, preferably half circumference.

[0044] Alternatively, it is provided that said lower curvilinear wall 24 traces a portion of a geometric conic section, i.e. for example from a quarter to two thirds of an arc of a circle, from a quarter to two thirds of a portion of an ellipse, a portion of a parabola, a portion of a hyperbola.

[0045] Alternatively, it can be provided that the upper 23 or lower 24 curvilinear wall traces at least a portion of a geometric polygon, for example as shown in Figure 11.

[0046] Both the upper curvilinear wall 23 and the lower curvilinear wall 24 respectively comprise a concave portion facing said space for the insertion of said at least one portion of said electronic label 100.

[0047] Advantageously, the fact that the lower curvilinear wall 24 traces an arc of a circle or an arc of a conic section of such dimensions makes it possible to achieve even increased bending and accommodate different electronic labels of different and even greater sizes.

[0048] Even more preferably, as shown in particular in Figures 5, 6 and 7, said lower curvilinear wall 24 comprises a second curvilinear portion 242 extending from the lower end 122 of said back wall 12.

[0049] Said second curvilinear portion 242 comprises a concave portion in the direction opposite said concave portion of said lower curvilinear wall 24.

[0050] Advantageously, said second curvilinear portion 242 allows the lower curvilinear wall 24 to have an even greater bending configuration and to be more elastic.

[0051] Alternatively, in place of the second curvilinear portion 242, it is possible to provide that said lower curvilinear wall 24 comprises a spring portion as shown in Figure 11. Said spring portion is, for example, comprising an undulated portion, or a Z-shaped portion, or an S-shaped portion, or a curvilinear portion with upward concavity followed by a curvilinear portion with downward concavity, or vice versa; or, not shown in the figures, said curvilinear portion with inward concavity followed by said curvilinear portion with outward concavity, or vice versa.

[0052] Preferably a thickness of said upper curvilinear portion 23 and a thickness of said lower curvilinear portion 24 are respectively less than a thickness of said back wall 12.

[0053] It is possible to envisage that the thickness of said back wall 12 means the greater thickness of said back wall 12, in the sense that it is not necessary that the whole back wall 12 has the same thickness, for example, the back wall 12 might not have the same thickness if there were ribs inwardly or outwardly or elements extending orthogonally from the rear face 13 outwardly, such as, for example, slide-like coupling elements 40 in Figures 1-7, 11, 19 or the arm 50 of Figure 8 which increase the rigidity of the back wall 12.

[0054] Advantageously, the reduced thickness of the curved portions 23 and 24 allows them to be more elastic.

[0055] Preferably the thicknesses of the curvilinear walls 23 and 24 are less thick than the thickness of the back wall 12. Advantageously, the lower thickness of the curvilinear walls 23 and 24 makes it possible to make the holder device 10 more elastic to such an extent that it becomes essentially universal for mounting most electronic labels of different sizes on the market.

[0056] Even more preferably, a thickness of the back wall 12 is expected to be in the ratio of 3 / 2 with respect to a thickness of the curvilinear walls 23 and 24, e.g. the back wall 12 is 1.5 mm thick and the thickness of the curvilinear walls is 1.0 mm.

[0057] Preferably said upper transverse wall 25 and said lower transverse wall 26 comprise respectively at least one reinforcement portion 251, 261 of greater thickness than a remaining portion of a rectilinear transverse part.

[0058] The reinforcement portions 251 and 261 make the respective rectilinear transverse walls 25 and 26 stiffer so that they do not break when subjected to stress due to particularly large electronic labels than when the curvilinear walls 23 and 24 are in the resting configuration.

[0059] The holder device 10 according to the present invention is made as a single piece by means of an injection moulding technique.

[0060] Manufacture by injection moulding makes it possible to create shapes such as those described above and in the figures that would otherwise be impossible to create in the case of extrusion because all the elements would have the same width in the longitudinal direction.

[0061] Even more advantageously, as shown for example in Figure 8, the holder device comprises at least one gripper-like coupling element 15 adapted to hold at least one sign or label 101 like the one shown in the figures. Said gripper-like coupling element 15 is made as a single piece and rises from a rear face 13 of the holder device 10. Preferably said gripper-like coupling element 15 extends for a smaller width than the width of the section bar 11 along the longitudinal direction.

[0062] Alternatively, it is possible to provide that the gripper-like hook 15 can also be lateral or upper or lower to mount other types of labels or markers.

[0063] As shown in the figures, the holder device 10 comprises a rear face 13 which is opposite said space for insertion of said at least a portion of said electronic label 100. The rear face 13 also means the portion outside the two tabs 21 and 22.

[0064] As shown in particular in Figures 1, 2, 4, 8, 9, 10, 13, 14, 15, 17 and 18, said holder device 10 comprises at least one coupling element 15, 30, 31, 32, 40, 41, 50, 51, 60 as a single piece, which protrudes from said rear face 13 and is adapted to be coupled to other display elements.

[0065] Said at least one coupling element 15, 30, 31, 32, 40, 41, 50, 51, 60 comprises at least one portion extending along a longitudinal direction for a length less than a width of the section bar 11.

[0066] Longitudinal direction means a direction parallel to the width of the section bar 11, i.e. in Figures 5-8, 11, 12 and 16 the longitudinal direction is perpendicular to the sheet.

[0067] For example, Figures 1-7 show a coupling element 40, which is an orthogonal coupling element in the form of a slide so that the holder device 10 can be mounted with display elements such as arms or other types of counter or shelf display elements. In particular, as shown in Figures 1-7, there are two slide-like coupling elements 40 that are orthogonal and have smaller widths than the longitudinal width of the section bar 11.

[0068] Note that orthogonal means an element rising from the rear face 13 of the section bar 11. The element rising orthogonally may rise from the rear face 13 of the section bar 11 so that its base portion is at right angles to the rear face 13, or the angle may deviate from the right angle by a range of values including rises along different angles, as for example shown in Figures 16 and 17 wherein the element 51 rises substantially parallel to the back wall 12 and then extends upwards to form two clips. For example, Figures 1-7 show the holder device 10 comprising an open hook-shaped coupling element 30 adapted to mount different types of display elements. The coupling element 30 is an open hook-shaped coupling element comprising an open curvilinear portion for coupling engagement to a respective display element of complementary shape. In the figures, it is shown that the coupling element 30 comprises an opening facing upwards to show an internal concavity of the coupling element 30. The coupling element 30 extends along the longitudinal direction for a shorter length than the longitudinal width of the section bar 11.

[0069] For example, Figures 9 and 10 show the holder device 10 with a coupling element 60 in the form of a closed hook or joint adapted to mount different types of display elements. The joint-shaped coupling element 60 comprises a curvilinear portion comprising a through opening in the longitudinal direction, wherein said through opening is adapted to let a longitudinal portion of a display element pass through. The joint-shaped coupling element 60 extends along the longitudinal direction for a shorter length than the longitudinal width of the section bar 11.

[0070] For example, Figure 8 shows a coupling element 50 which is an arm-shaped coupling element that is a single piece with said holder device 10 and wherein said arm is mounted for example with a joint 80 in Figure 8, or alternatively the arm 50 is a single piece with the joint 80. It is possible that said arm 50 can be mounted with other types of display elements such as bases or magnetic bases as shown in Figure 18. The arm 50 is mounted with a base or more preferably as shown in Figure 18 the arm 50 is a single piece with the base. The width of the arm-shaped coupling element 50 is less than the width of the section bar 11 in the longitudinal direction, while the width of the base is greater than the width of the section bar 11 and in particular greater than the width of the back wall 12.

[0071] For example, it is shown in Figures 12 and 13 that the holder device 10 may comprise two gripper-like coupling elements 15 as a single piece rising from the rear face 13.

[0072] For example, in Figures 12 and 13, it is provided that the holder device 10 comprises an orthogonal coupling element 31 which rises from the rear face 13 at the outer surface of the upper tab 21 and is a single piece with it. Said orthogonal coupling element is in the form of a hook with the opening facing downwards and has a width less than the width of the section bar 11. Alternatively, it may be provided that said orthogonal coupling element 31 may rise from the rear face 13 at the outer surface of the lower tab 22. It is also possible to provide two orthogonal coupling elements 31 rising from the outer surface of the upper tab 21 and the outer surface of the lower tab 22, respectively.

[0073] For example, in Figure 14, the holder device 10 comprises two clip-shaped coupling elements 32 that rise from the rear face 13 and have a width less than the width of the section bar 11 along the longitudinal direction.

[0074] For example, in Figure 14, it is also shown that the holder device 10 comprises a gripper-like coupling element 16 as a single piece that rises from the rear face 13.

[0075] For example, in Figure 15, the holder device 10 comprises two coupling elements in the shape of a tip 41 as a single piece and rising from the rear face. These two tip-shaped coupling elements 41 extend for a smaller width than the width of the section bar 11 along the longitudinal direction.

[0076] For example, Figures 16 and 17 show that the holder device 10 may comprise a curved arm-shaped clip-like element 51 rising from the rear face. Said curved arm-shaped coupling element comprises at least one slide-like portion which has a width less than the width of the section bar 11, while an upper portion in the form of two clips extends for a width greater than the width of the section bar 11 with respect to the longitudinal direction.

[0077] It follows that said at least one coupling element 15, 30, 31, 32, 40, 41, 50, 51, 60 comprises at least one portion extending along a longitudinal direction for a different length with respect to a width of the section bar 11, whereby different means either shorter or longer than the width of the section bar 11, in particular different means different from the length of the back wall 12. It should also be noted that the back wall 12 may also have different lengths as shown in particular in Figures 9, 10, 17 and 18.

[0078] Advantageously, the holder device 10 may provide a plurality of coupling elements 15, 30, 31, 32, 40, 41, 50, 51, 60 even of different types from those depicted in the figures by way of example, as other types of coupling elements may be provided for mounting the holder device 10 with other types of display elements.

[0079] Advantageously said plurality of coupling elements 15, 30, 31, 32, 40, 41, 50, 51, 60 are as a single piece with the holder device 10 as the injection moulding technique allows them to be moulded in one piece and thus also the coupling elements 15, 30, 31, 32, 40, 41, 50, 51 and 60 can extend orthogonally with respect to the section bar 11 and at least a portion thereof extends along a longitudinal direction for a length less than the width of the section bar 11 as shown in particular in Figures 2, 4, 9, 10, 12-15, 17, 18 which is not possible with extrusion techniques.

[0080] Advantageously, each coupling element 15, 30, 31, 32, 40, 41, 50, 51, 60 of said plurality of coupling elements 15, 30, 31, 32, 40, 41, 50, 51, 60 due to injection moulding comprises at least one portion which is shorter in the longitudinal direction than the width of the section bar 11 and this allows for a more performing coupling element 15, 30, 31, 32, 40, 41, 50, 51, 60 adapted to be coupled to a multiplicity of display elements of different widths, making the holder device 10 universal.

[0081] Advantageously said at least one coupling element 15, 30, 31, 32, 40, 41, 50, 51, 60 may have any of the following shapes as shown in the figures: gripper-like coupling element 15, open hook-shaped coupling element 30, orthogonal coupling element 31, clip-shaped coupling element 32, slide-like orthogonal coupling element 40, tip-shaped coupling element 41, arm-shaped coupling element 50, clip-shaped curved arm-shaped coupling element 51, joint-shaped coupling element 60.

[0082] Different solutions can be implemented with the same form of holder device 10, such as a horizontal tubular affixing system, which is very popular in departments such as the fruit and vegetable sector, a system that allows the electronic label to be tilted in relation to the customer, widely used in the fresh-food sector for use on products that include this possibility, such as stands, bases, magnetic bases, tray attachments, etc., self-supporting magnetic systems, which are very popular in the DIY and consumer electronics sectors, systems for use with a series of "slide" accessories, for all other sectors, for wooden shelves, for various thicknesses and for cardboard displays.

[0083] Alternatively, the upper 23 and lower 24 curvilinear walls can be of the same shape. This alternative is not shown in the figures.

[0084] According to the latter alternative, it is preferable to provide that said upper elastic tab 21 has the same shape as said lower elastic tab 22.

[0085] Even more preferably in the latter alternative, it can be provided that said resting configuration of said upper tab 21 provides that said upper transverse wall 25 forms a first angle α with said back wall 12, wherein said first angle α is between 45 and 80 sexagesimal degrees, wherein said increased bending configuration of said upper tab 21 provides that said upper transverse wall 25 forms a second angle β with said back wall 12, wherein said second angle β is between 75 and 120 sexagesimal degrees, wherein said resting configuration of said lower tab 22 provides that said lower transverse wall 26 forms a third angle γ with said back wall 12, wherein said third angle γ is between 45 and 80 sexagesimal degrees, wherein said increasing bending configuration of said lower tab 22 provides that said lower transverse wall 26 forms a fourth angle δ with said back wall 12, wherein said fourth angle δ is between 75 and 120 sexagesimal degrees.

[0086] In the latter alternative, the upper curvilinear wall 23 may also comprise the second curvilinear wall 242 or a spring-shaped wall as described above.

[0087] Alternatively, it is possible to provide that the retaining elements 27, 28 are not arranged on the end of the respective transverse wall 25, 26, but may, for example, rise from any portion of the transverse wall 25, 26.

[0088] It is also possible to provide that said retaining elements 27, 28 may be more than one and that other retaining elements 27, 28 may rise from different positions of the respective transverse wall 25, 26 so as to be able to adapt to support any type of electronic label of any shape and size.

[0089] A further alternative is provided in Figure 19 where an alternative holder device 10 is shown comprising the section bar 11 comprising the back wall 12 which extends longitudinally, the upper tab 21 which has a square right angle shape and the lower elastic tab 22 comprising the lower curvilinear wall 24. The upper tab 21 does not have an upper curvilinear wall and is therefore less elastic than the lower elastic tab 22 because it has a square shape. The fact that the upper tab 21 is square and at right angles does not allow the upper tab 21 to switch from the resting configuration to the increased bending configuration. In this alternative, only the lower elastic tab 22 is configured to switch from the resting configuration to the increased bending configuration having the lower curvilinear wall 24. It is also evident to a person skilled in the art that to achieve the technical result of the present technical solution, it is sufficient that only one of the two tabs 21 or 22 comprises the curvilinear wall, while the other of the two tabs may not comprise the curvilinear wall as shown in the embodiment in Figure 19 where the upper tab 21 does not comprise the upper curvilinear wall. It is clear to a person skilled in the art that it is possible to swap the upper tab 21 with the lower tab 22.

[0090] Alternatively, as shown in Figure 20, a holder device 10 is shown comprising at least one curvilinear wall 23, 24 comprising a single through opening 245 to make the tab 21, 22 more elastic.

[0091] Still alternatively, it is possible to envisage that said curvilinear wall 23, 24 may comprise a multiplicity of through openings 245 to make the tab 21, 22 more elastic.

[0092] According to the last two alternatives, it is preferable that if the thickness of the curvilinear wall 23, 24 is equal to the thickness of the back wall 12, said curvilinear wall 23, 24 comprises at least one through opening 245.

[0093] The invention thus conceived is susceptible to several modifications and variations falling within the exclusive scope of the claims. In practice, the materials used, as well as their dimensions, can be of any type according to the technical requirements.
