Each coupling device 4 comprises a holder 6 for engagement with the crossbar 5, and a resilient joint 7 arranged between the post 3 and said holder 6. The coupling device 4 may comprise further elements arranged between the resilient joint 7 and the holder 6 and/or the resilient joint 7 and the post 3.


The length adjustable posts 3 may be configured in any suitable way in order to allow adjustment of the length (or height) of the post 3, and thereby the height of the display system arrangement 1. The post 3 may comprise a first tube 3′ and a second tube or rod 3″, the outer diameter of the second tube 3″ being smaller than the inner diameter of the first tube 3′ in order for the second tube or post 3″ to be inserted into the first tube 3′ in a telescopic relation, and means 8 for fixating the position of the second tube or post 3″ in relation to the first tube 3′. The length is adjusted by inserting or extending the second tube 3″ into or out of the first tube 3′ and fixating the second tube 3″ at the requested position. The means 8 for fixating the position may be a conventional clamp having an eccentric lever. In one embodiment the posts 3 are telescopic masts. It shall also be pointed out that each post 3 may comprise more than two telescopically arranged tubes. The height of the display system arrangement is usually in the range of 2-4 meters, however the invention is not limited to this range and higher as well as lower display system arrangements are feasible.


The coupling device 4 comprises the resilient joint 7 and said holder 6. The holder 6 is configured to connect to the crossbar 5 using any suitable connection means 9. In the preferred embodiment the connection means 9 of the holder 6 comprises a lever arrangement securing the crossbar 5. The coupling device 4 should preferably be able to be positioned anywhere along the crossbar 5 making the display system more flexible concerning the positioning of the posts 3 due to the shape of the crossbar or any differences in height or unevenness on the ground or floor for example. In one embodiment the connection means 9 and the crossbar 5 are configured to allow the connection means 9 to slide along the crossbar 5. The coupling device 4 may comprise a fixation means, such as a screw, in order to fixate the position of the coupling device 4 on the crossbar 5. In one embodiment the display system comprises at least two crossbars preferably one of the crossbars is arranged at the lower end of the sheet of material. The lower crossbar does not need to be connected to the posts 3.


The resilient joint 7 is configured to allow inclination or bending, preferably in any direction meaning that the resilient joint 7 may be bent for example forward or backward or to the sides or in any direction in relation to the corresponding post. In one embodiment the resilient joint 7 is a coil spring. In another embodiment the resilient joint 7 is a tube or rod made of a resilient material such as rubber.


The coupling device 4 may be connected to the post 3 using any suitable means 10. In one embodiment an upper end of the post 3 is hollow having an inner diameter and the means 10 has an outer diameter smaller than said inner diameter to allow insertion of the means 10 into the upper end of the post 3. In another embodiment the top section of the post 3 has an outer diameter and the means 10 of the coupling device 4 is hollow with an inner diameter larger than said outer diameter in order to allow insertion of the top section of the post 3 into the means 10 of the coupling device 4. In another embodiment the coupling device 4 is connected to the post by means of a clamp. The resilient joint 7 is arranged between the means 10 and the holder 6. It shall be pointed out that the coupling device 4 may comprise a rod, or the like, arranged between the resilient joint 7 and the holder 6 such that there is a distance between the resilient joint 7 and the holder 6. The coupling device 4 may also comprise several resilient joints arranged in series between the post 3 and the holder 6.


The coupling device 4 may be arranged at any position along the post 3. In one embodiment each coupling device 4 is connected to the corresponding post 3 at an upper end thereof.


Each post preferably comprises a structural support 11 in order to provide stability and preventing the display system arrangement 1 from tipping over. The support 11 may be a foot, bearing pile, braces or supporting legs arranged at the lower end of the post 3 and releasably connected to the post 3. The structural support may be length adjustable, foldable, extendable, or the like, in order to be transported in a convenient way.


Referring now to FIGS. 4 and 5 (the lines represent the center axis of the resilient joint 7). FIG. 4 disclose the system during adjustment of the length of the posts 3. By having a resilient joint 7 configured to allow inclination or bending in any direction the length of the posts 3 may be adjusted one at the time in a controllable fashion without damaging the sheet of material. During the length adjustment of for example two adjacent posts (first and second post) with a crossbar extending between the posts 3 the first post will be raised or lowered using the configuration for adjusting the length of the post. The adjustment will place a load on the resilient joints 7 of the two posts 3. This results in that the resilient joint 7 will tilt or bend allowing the holder 6 to go from a first position A at a first angel in relation to the tube to a second position B at a second angle (the arrow represents the change from position A to position B). The post 3 which length has not yet been adjusted may then be adjusted to the same length as the adjusted post resulting in that the resilient joint 7 will return to an unloaded state. It shall be pointed out that the posts 3 may have different lengths during display of the sheet of material 2, and then the resilient joints 7 are in a tilted or bent state during display.


The coupling device may be arranged so that the center axis of the resilient joint 7 extends along the center axis of the corresponding post 3 when the coupling device 4 is in the first position A, FIG. 5. The coupling device 4 may further be arranged so that the center axis of the resilient joint 7 is parallel with the center axis of the corresponding post 3 but the center axis of the joint 7 does not extend along the center axis of the corresponding post 3. In one embodiment the coupling device is arranged so that the center axis of the resilient joint 7 is non-parallel to the corresponding post 3, for example the center axis of the joint 7 is perpendicular to the post 3, i.e. protrudes at an angle in relation to the post 3.


The present invention facilitates displaying a curved sheet of material. Therefore in one embodiment the display system arrangement comprises at least three posts 3 and wherein the crossbar 5 may be curved along the length thereof, in the horizontal direction and/or vertical direction.


The sheet of material 2 may be rolled up and arranged on the crossbar 5 using any suitable means. The sheet of material may be displayed by pulling the sheet of material downwards and by securing it. The sheet of material 2 may also be arranged in a similar manner on a crossbar 5 arranged at the lower ends of the posts 3.


The present invention further relates to a display system comprising a display system arrangement 1 according to the present invention and a sheet of material 2 where the sheet of material may be a fabric or a printed fabric.
