Fig. 5 is a schematic plan view of a design according to Fig. 4 with a memory area.

In Fig. 1, 1 denotes a rectangular frame, which is composed of individual struts Ia and Ib and can be stiffened by means of clamping elements Ic as ropes. On opposite sides of the frame 1 is a respective transport means in particular in the form an endlessly circulating chain 2, 2 ', wherein between the opposite chains

2 and 2 ^1, the advertising surface W (FIG. 3) not shown in FIG. 1 is suspended or clamped, which preferably consists of a coated, textile material web. 2 a and 2 b deflection rollers for the chains or sprockets are referred to, which are rotatably mounted on the frame 1. With the sprockets 2a, 2a 'and 2b, 2b' is in each case a deflection roller

3 connected to the advertising space W is performed. These guide rollers 3 form a shaft between the sprockets 2a, 2a 'and 2b, 2b', by which the opposite sprockets are synchronized. The guide rollers 3 are coaxial with the sprockets 2a and 2b. Furthermore, the diameter of the guide rollers 3 is preferably equal to that of the sprockets 2a and 2b. 4 with an electric drive motor is referred to, which drives in the illustrated embodiment, the lower conveyor chain 2 via the sprocket or gear formed as sprocket 2a. Here, the electric motor 4 can drive the sprocket 2a directly or via a transmission, so that the electric motor 4 can be positioned in various ways. The sprockets 2b and 2b ¹ with the intermediate shaft or guide roller 3 'are driven by the chain 2 and 2'. The deflection rollers 3 and 3 'serve to tension the advertising space W in the direction of rotation.

Fig. 2a and 2b show a cross section along the line A-A in Fig. 1 with a preferred embodiment of the transport means in the form of a double chain. On the frame strut Ib on both sides guide rails 5 and 5 ', for example. Attached by means of screws. In this exemplary embodiment, the guide rails 5 consist of a hollow profile which is open at the bottom and in which an insert 5a is arranged with a recess for receiving at least the upper part of a first link chain 2 designed similarly to a bicycle chain. The insert 5a may, for. B. consist of self-lubricating plastic.

At the first link chain 2 corresponding in construction of a bicycle chain, a second chain 20 of the same design, for example, is fixedly mounted on the exposed lower or outer side via common chain pins, so that the two chains 2 and 20 form a unit. The chain 2 is guided at the deflection points by the sprocket 2a and 2b, while the chain 20 is exposed in the deflection region. On the exposed chain 20 hang at intervals bracket 21, which are guided by eyelets Wl along the edge of the advertising space W. The advertising space W is thus connected via the bracket 21 as an endless belt with the chain 20 and the transport chain 2, wherein the transport chain 2 as a guide device for the Advertising surface W is used by the transport chain is at least partially guided in guide rails 5 between the deflection or sprockets 2a, 2b.

Preferably, the brackets 21 are formed as spring elements, so that the opposite sides of the advertising area W between the brackets 21 are kept taut. In a simple embodiment of the construction, the advertising surface W is guided as an endless belt around the two deflecting rollers 3 and 3 'on opposite frame sides, so that a billboard image can be presented on the section of the advertising surface W lying on the front side, while that behind the frame 1 Section of the advertising space carries another advertising image that can be moved by the transport device 2 to the front. Instead of two separate advertising images and a continuous advertising image can be presented in such a way that the transport chain 2 rotates continuously.

To increase the advertising space, the advertising area W is preferably deflected several times in a storage area on the back of the frame 1, so that overall a greater length of the advertising space W is available for the presentation.

Fig. 3 shows in a plan view of the structure schematically the arrangement of a plurality of deflection points 30, 31 behind the frame 1, around which the advertising space W is guided. In the exemplary embodiment according to FIG. 3, guide rollers 30 and 31 are rotatably mounted behind the frame 1 on an attachment, not shown, of the frame, of which the guide rollers 30, 30 'are preferably arranged at a small distance from each other and the guide rollers 31, 31' one have greater distance from each other, so that the largest possible length of the advertising space W results. The guide rollers 31, 31 'can also be arranged close to the front deflecting rollers 3, 3'.

In the reproduced in Fig. 3 guide the advertising space over a plurality of guide rollers 30, 31 behind the presentation side, the transport chain 2 extends in the same way to the guide rollers 30 and 31 attached sprockets, wherein for stabilization, the chain respectively on the sections between the guide rollers 30th , 31 is guided in rails 5, as shown in FIG. 2. These serving as shafts between the upper and lower sprockets deflection rollers 30,31 are not driven directly, but are offset by the transport chain 2 in rotation. It is also more than the four shown in Fig. 3 deflection rollers 30, 31 are arranged behind the presentation page between the guide rollers 3 and 3 'in order to increase the memory area for advertising space.

The frame 1 with the deflecting rollers 3, 30 and 31 rotatably mounted thereon can be set up freely on a stand, not shown, or, for example, on the frame in front of a building.

Instead of reproducing the transport device in the form of a double chain 2, 20, a conveyor belt may be provided on which the advertising space W is attached.

The frame can z. B. dimensions of 15 x 15 meters have. It is also possible to arrange the guide rollers 3 and 3 'on the lower and upper side of the frame 1, so that the advertising surface W is moved from top to bottom or vice versa. In order for such a vertical arrangement of the advertising surface W, the deflecting rollers 3, 30 and 31 serving as shafts between the sprockets 2a, 2b can not be supported at predetermined intervals, for example, by a ball bearing.

For tensioning the advertising surface W in the direction of rotation, at least one pair of sprockets 2 a or 2 b can be adjustably mounted on the frame 1. Also, at least a pair of sprockets can be guided with the axes in oblong holes and acted upon by springs such that the advertising space W is held in the direction of rotation by the springs tensioned.

According to a further embodiment, the second chain 20 may serve as a drive chain, so that the first chain 2 serves only for guidance.

Fig. 4 shows schematically in a perspective view another embodiment in which an approximately cube-shaped frame 10 is formed, wherein the edges of the cube are formed by the struts 10a and 10b of the frame. At the four corners of the cube-shaped frame 10 are respectively guide rollers 3, 3 'and 33, 33' rotatably mounted on the frame 10 and connected to sprockets 2a, 2b, 2c and 2d, where the transport and guide chains 2 and 2 'are deflected. 4, the drive motor for at least one Ket tenradpaar 2a, 2a 'denotes. Otherwise, the construction may correspond to that in FIG. 1, wherein FIG. 1 can be seen as a view of the cube-shaped structure from the left in FIG.

The cube-shaped structure according to FIG. 4 can be arranged, for example, around a building or a container. Likewise, a free installation of the cube-shaped frame is possible. Instead of the cube shape, a polygon shape or a triangular shape with an edge length of up to 40 m can also be provided in plan view.

In a modified embodiment, the pairs of sprockets 2a, 2a 'and 2b, 2b' are interconnected by a shaft on which the guide rollers 3 and 33 are freely rotatably mounted, because the guide rollers for driving the circulating advertising space W are not needed and serve only for the deflection and tension of the advertising space W.

As schematically indicated in FIG. 4, at least on one side of the cube-shaped structure behind the presentation side a storage area of the advertising area W can be formed by multiple deflection corresponding to the arrangement according to FIG. 3, wherein on the presentation side the advertising area W is not continuous around the frame 10 but at a point U is interrupted, so that at this point of interruption U (Fig. 5), the advertising space W can be deflected into the storage area behind the presentation page. FIG. 5 shows, in a plan view, schematically such a storage area S with deflecting rollers 30, 31 and 32 around which the advertising area W is guided. As in the embodiment of Fig. 3, the guide rollers 30 to 32 are rotatably mounted on a lug on the frame 1 and 10, wherein the guide rollers are connected to sprockets or rotatably mounted on axes of the sprockets.

At 34, a guide roller is designated with corresponding sprockets through which the advertising space W at the point of interruption U is again deflected into the plane between the two guide rollers 3 and 3 'at the edges of the cube-shaped structure.
