Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to the field of display systems for displaying a message of a sheet of material. Further, the present invention relates specifically to the field of display system arrangements for retaining said sheet of material. The display system arrangement comprises an elongated support profile and at least one retainer profile, the support profile comprises a longitudinal channel, which is open towards a lower side of the support profile and which present a first surface and a the first surface opposite second surface, the at least one retainer profile being insertable in said channel in order to form a retaining interface between said first surface of the channel and a first surface of the retainer profile, the retainer profile comprising a the first surface reverse second surface. The invention also relates to a display system comprising such a display system arrangement.

BACKGROUND OF THE INVENTION

It is commonly recognized that in order to communicate a company identity, company profile, logotype, product, etc. on fairs, exhibitions, lectures, in shops, etc., different types of portable display systems are easy to use and gives a professional appearance. Display systems are arranged to display a sheet of material, such as a banner, poster, print, or the like, which may be made of a laminated sheet of material, a cardboard or paper sheet of material, or a flexible sheet of material made of fabric or vinyl.

A banner stand and a roll up are two frequently used display systems. In brief the banner stand comprises a stand, a supporting rod, a banner, a top profile and a bottom profile, and the roll up comprises a stand accommodating a cassette with the banner, a supporting rod and a top profile.

The possible use of many different types of sheet of material, which have different surface structure and different thickness, makes it difficult to use the same top profile, which is designed to retain the banner. That is, for instance a banner made of fabric, or a banner made of vinyl having dimples, or a banner having a glossy and/or a very even surface is harder to retain then a banner having a laminated surface. A known way of retaining different types of banners in one and the same top profile is to use several locking screws distributed along the top profile, which locking screws may be tightened as much as needed depending on the banner in question. This known top profile is shown in FIG. 10.

However, during mounting a hole must be drilled in the top profile for each locking screw, the nut must be axially moved to the right position in the support profile, and the locking screw must be tightened by means of a tool. Thus, the mounting of the banner is complicated, time consuming and requires tools. Thus, the known top profile of the display system does not admit easy mounting or change of a banner, which for instance may by required on a fair or exhibition, or in a shop.

Another known display system arrangement is a clamp profile having an eccentric lock design. However, it is difficult to mount the banner in a straight manner and the banner most often gets wrinkles and folds during the fastening operation. In addition this type of display system arrangements are only suitable for banners having a predetermined thickness.

OBJECT OF THE INVENTION

The present invention aims at obviating the aforementioned disadvantages of previously known display systems, and at providing an improved display system arrangement. A primary object of the present invention is to provide an improved display system arrangement of the initially defined type which is structured to ensure easy mounting and dismounting of a sheet of material. It is another object of the present invention to provide a display system arrangement, in which the mounting and dismounting of a sheet of material does not need any tools. It is another object of the present invention to provide a display system arrangement which may be used for a wide range of sheet of materials, independent of the material, surface structure, thickness, etc.
