Advertising standard for mounting and stretching of posters

Description

[0001] The present invention concerns an advertising standard for mounting and stretching posters and of the kind indicated in the preamble of claim 1.

[0002] Prior art advertising posters for suspending large advertising displays or posters have very complicated structure, why they are expensive and cumbersome to work with, due to that is that by prior art advertising standards it is also necessary to use cover sheets of transparent material, by way of example acrylic or glass, which particularly in the case of very large advertising displays, by way of example of the magnitude (1600 x 2200) mm imply large extra costs.

[0003] EP-A2-1 020 837 discloses a prior art advertising standard system comprising a construction consisting of two vertical uprights, one horizontal girder and fastened there between a plate element for posters or advertising displays, where the uprights and the girder are constituted by hollow, uniform metal profiles having substantial triangular cross section with an opening in connection with a vertex. Said uprights and said girder are mutually connected in such a manner with mitre joints, that said opening forms an internal, continuous slot in which edge parts of said plate element may be accommodated and fixed.

[0004] The invention has the purpose of indicating an advertising standard for mounting and stretching large posters and of the kind mentioned in the introduction, and which by means of simple measures facilitate mounting and stretching large advertising displays or posters, particularly on detached advertising standards.

[0005] The advertising standard according to the invention is defined by the features of claim 1. It is characterised in that the girder near and along an upper edge area of the support board is provided with a particularly profiled holder strip which, together with the girder form a holder groove arranged to receive and fix an upper thickened edge profile of a poster, and that the support board is provided with a bottom strip along a bottom edge, in which there is fastened a number of tightening means adapted for interacting with a lower holder profile, which is provided with a holder groove at least at the top, the groove being arranged to receive and fix and lower thickened edge profile of the poster.

[0006] By means of simple measures it hereby becomes easier to mount and stretch large advertising displays or posters, particularly on detached advertising standards. It has thus appeared that is that large advertising displays printed on woven cloth of textile or synthetic fibre, plastic film or moist-resistant paper with good durability may be mounted without any problems and may continuously be kept stretched by means of a device according to the invention.

[0007] Suitably, the advertising display according to the invention is thus designed that said lower holder profile is made symmetrical with an upper and a lower holder groove.

[0008] The advertising standard according to the invention is preferably designed so that said bottom strip is formed with protruding flanges arranged to constitute lower fastenings for a number of tightening devices in the form of special tightening bolts, tightening springs or simple threaded screws.

[0009] Alternatively, the advertising standard according to the invention is designed so that the tightening bolts comprise an end part with a transverse, cylindrical holder part which is arranged for being received in a lower holder groove of the holder profile.

[0010] Or, the advertising standard according to the invention is thus made so that a lower holder profile is formed upwards with an upper holder groove and formed downwards with a number of threaded holes arranged for receiving threaded ends for lugs or tightening screws in the shape of simple threaded screws.

[0011] According to a further alternative embodiment, the advertising standard according to the invention is shaped so that the tightening means comprise tightening springs the lower ends of which are connected with a projecting flange of the bottom strip, and the upper end of which is connected with connecting parts comprising holder parts arranged to be received in lower holder groove of the holder profile.

[0012] The invention is explained in more detail in the following in connection with the drawing on which:

Fig. 9

shows a plan view of a preferred embodiment of a tightening means for fastening the bottom strip in Fig. 8 according to the invention.

[0013] The advertising standard 2 shown in Figs. 1 - 3 is built up of strong profiles, by way of example of stainless steel with mainly triangular cross-section, in the shape of two vertical uprights 4, which are fastened in the ground, and a horizontal girder 6, which are mutually mitred and assembled around a rectangular support board 8 of plywood, MDF-board, or corresponding material with a smooth surface so that the support board 8 is fixed along three outer edges in an inward facing slit between the lateral flanges of the uprights 4 and the girder 6.

[0014] Along the bottom edge of the support board 8, as shown in Figs. 4, 6 and 7, there is fastened a bottom strip 10 with protruding flanges 12 in which a number of tightening devices 13 in the form of special tightening bolts 14 or springs 16 are attached at the bottom. The tightening devices 13 upwardly engage a lower holder profile 18 which at least upward is provided with a recessed holder groove 20 arranged to receive and fix a lower thickened edge profile 22 of a poster 24. Downwards, the holder profile 18 has either a corresponding recessed holder groove 21 for receiving cylindrical, transverse holder parts 23 of the tightening bolts 14 (Fig. 6). Alternatively, the holder profile 18 is provided with a number of threaded holes arranged for receiving either threaded ends of lugs in connection with the tightening springs 16 (Fig. 7) or for receiving simple threaded screws 15 (Fig. 4).

[0015] Besides, in Fig. 7 is shown that the tightening springs 16 may be connected upwards with connecting part s 25 with cylindrical transverse holder parts 27 which are arranged for being received in a lower recessed holder groove 21 of the holder profile 18.

[0016] Upwards, as shown more clearly in Fig. 5, the poster 24 has also a thickened upper edge profile 26 which is arranged for being inserted and fixed between a lower side edge profile of the girder 6 and a specially profiled holder strip 28, which is fastened to the said side edge profile of the girder 6 close to the support board 8 so that the poster 24 may be stretched along the surface of the support board 8. The length of the holder strip 28 is adapted so that there is a certain distance between the opposite end parts of this and the uprights 4, that is so that there will be enough space to insert the thickened upper edge profile 26 of the poster 24 behind the holder strip 28. Possibly, at an end part opposite the insertion end, the holder strip 28 may comprise a stop device arranged for interacting with an end part of the thickened edge profile 26 so that the poster 24 is automatically centred in relation to the support board 8.

[0017] The bottom strip 30 shown in Fig. 8 has protruding lateral flanges 32 and is fastened along the bottom side edge of a support board 8. In both lateral flanges 32, the bottom strip 30 is provided with special fastening holes 34 having side apertures 36 opening at outer side edges 38 of the lateral flanges 32. The fastening holes 34 are arranged for receiving special, mainly cylindrical locking bolts 40 which are formed with a waist 42 enabling the insertion of the locking bolts 40 through the side apertures 36 so that a lower cylinder part 43 may be fixed in the fastening holes 34, kept in place by a disc-shaped stop plate 45. Below the cylinder part 43, the locking bolts 40 have stop plates 45 with an eye-shaped handle 44. Upwards, the locking bolts 40, above the waist 42, is provided with an connecting eye 46 for a tensile spring 48, the opposite end (not shown) of which is connected with the lower holder profile 18, by way of example by means of connecting parts 25 with cylindrical transverse holder parts 27 which are arranged for being received in the lower recessed holder groove 21 of the holder profile 18 (Fig. 7).

[0018] It is very easy to mount and keep tight the lower edge of a poster 24 which beforehand has been fastened in the upper holder groove 20 of a holder profile 18, by in turn inserting the locking bolts 40 through the side apertures 36, so that by the upward directed pull in the spring 48, the upper end of which is already connected with the lower holder groove 21 of the holder profile 18, the lower cylinder part 43 will automatically slide in place and be fixed in the fastening holes 34. Correspondingly, it will be very easy to dismount the locking bolts 40 by a downward pull before the locking bolts can be removed through the side apertures 36.

[0019] The described tightening principle may be used more generally in connection with MegaBoard™ or MegaStander™ for stretching and keeping tight large advertising displays.
