Description

advertising tower

The invention relates to an advertising tower for alternately visible, rolled up and unrolled web-shaped posters.

Advertising media with alternately visible posters are already known.

DE 41 19 088 A1 discloses an interchangeable poster device in which several posters are arranged on an endless belt which is guided over two rotatable rollers which run in parallel.

However, this invention has the problem that certain requirements are placed on the location selection. Since only one of two posters arranged on a tape is visible to the viewer and the tapes are arranged in parallel, the removable poster device must be set up so that it can be viewed from both sides.

DE 41 12 390 A1 describes a poster column for alternately visible posters. The invention provides web-shaped poster carriers which can each be wound up on a winding body and lie on the outer surface of a hollow cylinder in the unwound state. Several poster carriers are each attached to the hollow cylinder with their edge facing away from the winding body. The Winding bodies are held in a holding device which is rotatably mounted coaxially with the hollow cylinder with respect to the hollow cylinder, two winding bodies each being arranged close to one another such that when the holding device rotates, a poster carrier is unwound from one of these winding bodies and another poster carrier is wound onto the other of these winding bodies becomes.

DE 42 18 086 A1 and WO 93/24 920 A1 build on the aforementioned invention to a certain extent and disclose a combined advertising column, the upper section of which as advertising or display means, in particular as an alternating image device, preferably as an exchangeable poster device according to DE 41 12 390 A1 is formed and the lower portion of which is a telephone booth.

The above-mentioned interchangeable poster device is associated in particular with the problem that the poster often lies unevenly and with an air cushion on the contact surface. In addition, tear-resistant and expensive plastic films are required as poster material.

The object of the invention is therefore to develop an advertising tower for alternately visible, roll-up and roll-off web-shaped posters of the generic type in such a way that the poster material rests evenly and over the entire surface and without enclosed air cushions on the contact surface.

According to the invention, the object is achieved by an advertising tower consisting of an electric drive and an inner cylinder which is arranged centrally in a vertical support and which is designed with contact surfaces for the posters to be rolled up, the inner cylinder being made of transparent material clamped between supports and in the center of the inner cylinder there is a turnstile with a vertical shaft equipped with a reversible swivel drive, on which are attached below and above the inner cylinder between its vertical supports cantilevers, the ends of which are arranged between the inner and outer cylinders for poster drums wear. The supports of the outer cylinder have an upper part which is arranged with fastening means and supports the turnstile. inventions According to the supports of the outer cylinder and the vertical shaft of the turnstile are arranged on a base plate which is formed on its underside as a tread for support and guide rollers. Carrier and guide rollers are mounted on a cover plate that closes the advertising tower downwards. On the vertical supports of the inner cylinder, clamping devices are rotatably arranged on two bearings each, which leads the poster to be unrolled to the contact surface of the inner cylinder.

Advantageous embodiments of the invention provide that the pickup for the poster drum on the upper arm is designed as a radial bearing and on the lower arm as a ratchet bearing to prevent rotation and the poster drum is equipped with a journal on its upper installation side and a shaft on its lower installation side one end of a coil spring, in use as a torsion spring and the other end is arranged on the jacket of the poster drum.

Further advantageous refinements of this advertising tower according to the invention result from the features of claims 4 to 10.

The invention is associated with the particular advantage that web-shaped posters can be placed uniformly directly, without air cushions, on the contact surface of the inner cylinder. The poster is pressed onto the entire surface of the contact surface. This means that the poster material does not need to be particularly stable, nor are other additional aids required to keep the poster stable on the inner cylinder. Furthermore, the invention enables the adhesive effect caused by the vacuum between the poster and the contact surface to be overcome without any particular development of force.

The invention furthermore permits the use of posters made of normal paper with a weight of approx. 150 g / m ² . Since the poster is unrolled under constant tension from the poster drum and placed on the contact surface of the inner cylinder, it is not necessary to use special tear-resistant plastic films. In addition to the resulting cost advantage, the ecological effect should be emphasized, since the poster material can be recycled. The advertising tower according to the invention is to be described in more detail below in one embodiment.

The advertising tower is a round, cylindrical body, which is made up of the following components from bottom to top: a cover plate with the carrying and guide rollers mounted therein; an outer cylinder, which is built on a base plate, which has on its underside the treads for the support and guide rollers and on the top fastening means for the vertical supports of the outer cylinder are arranged. These supports have a round top as the upper end. This part forms the cover of the advertising tower and is equipped on its underside with fasteners for the vertical supports. If necessary, it forms the receptacle for the roof upwards. The windows of the outer cylinder are arranged between the vertical supports, the frames of which are formed by the vertical supports, the upper edge of the base plate and the lower edge of the upper part; an inner cylinder installed centrally in the outer cylinder. This is attached to the base plate and designed as a contact surface for the posters to be unrolled. The inner cylinder consists of transparent, curved panes, preferably plastic panes, which are clamped between the vertical supports of the inner cylinder, which are arranged behind the vertical supports of the outer cylinder; a turnstile arranged in the center of the inner cylinder, the vertical shaft of which is supported on the base plate and the lower side of the upper part. Booms are attached to this shaft below and above the discs of the inner cylinder between the vertical supports. At the end, between the inner and outer cylinders, each boom carries the receptacles for two poster drums arranged side by side. The wave is with one reversible rotary actuator. As a result, the arms of the turnstile can be pivoted back and forth between the supports. The receptacles for the poster drums are designed on the upper arm as a radial bearing and on the lower arm as ratchets, blocking the direction of rotation on one side. On the installation side, the poster drums are equipped with a rigid bearing journal. On the lower installation side, they are equipped with a shaft on which one end of a helical spring is attached in use as a torsion spring. The other end of the spring is attached to the jacket of the poster drum. When the shaft is firmly clamped, the spring is tensioned by turning the poster drum and thus a restoring force is generated to turn the spring.

To put the advertising tower into operation, the posters are attached to the jacket of the poster drums using adhesive strips and rolled up with the visible surface facing inwards.

After inserting the poster drum into the receptacles arranged on the outriggers of the turnstile, the posters are unrolled and their free ends are attached to the holder arranged on the vertical supports of the inner cylinder using suitable devices, for example sticking on a confectioning strip. With the help of the ratchets, a defined preload of the spring can be generated.

When the turnstile is swiveled, one poster per boom is unrolled from the poster drum while the spring preload is increased, while the other is rolled up on the poster drum using the spring preload. Of course, this process takes place simultaneously with all other poster drums arranged on the outriggers.

The windows of the outer cylinder can be opened to change the poster drums. Due to the round cylindrical shape of the advertising tower according to the invention, a lever linkage is provided for the opening movement of the window, with the aid of which the window is first pulled off the frame. Then the opening is carried out as a swivel movement upwards. Due to the different lengths of the levers, the Window sash achieved, whereby sufficient accessibility is achieved with reduced opening.

By assembling the posters on the poster drums, it is also possible to change them quickly and cost-effectively.

In the interior of the inner cylinder, lighting elements are attached to the vertical supports between the arms of the turnstile so that the contact surface is illuminated for night operation of the advertising tower during night operation.

The entire electrical device, including the control, is housed in a control cabinet in the area of the base plate. The necessary connections are transferred into the area of the cover plate by a slip ring, which is also attached to the base plate. The storage of the advertising tower is carried out by the support and guide rollers in the cover plate. The drive is designed with an electric motor, on the shaft of which a friction wheel is mounted, which acts against the running surface of the base plate and is arranged like the idlers.

The advertising tower thus presents itself as an independent unit that can be placed on any suitable surface with the cover plate. The installation can be done on the ground, but also on a flat roof of an existing building. But it is also possible to set up on a functional part, such as. B. a kiosk, the waiting shelter of a bus stop, a phone booth, a shopping cart shelter or the like.

In the following, essential pages of the invention will be explained in more detail with reference to drawings. Show it

Figure 1 is a perspective view of a clamping device.

2 shows the section through a detailed sketch with poster drums and clamping device;

Figure 3 is a plan view of the cover plate with the support and guide rollers mounted thereon. Figure 4 shows the section through the cover and base plate with support and guide rollers.

Fig. 5 is a schematic representation of an advertising tower erected on a kiosk.

In Fig. 1, an essential part of the advertising tower according to the invention, the clamping device 1, is shown in perspective.

With the help of the bracket 2, it is arranged on a vertical support of the inner cylinder. As can be seen from Fig. 1, the angled bearing arms 5, 6, 7 and 8 are rotatably mounted on the bearings 3 and 4. The pressure rails 9 and 10 are clamped between the angled bearing arms 5, 6, 7 and 8 and are pressed against the inner cylinder by the force of the tension spring 11 arranged between the bearing arms 5 and 6. In Fig. 1 it cannot be seen from the illustration that a tension spring is also arranged between the bearing arms 7 and 8.

FIG. 2 shows the clamping device 1 according to FIG. 1 in operation with two poster drums 12 and 13, which are attached between the inner cylinder 14 and the outer cylinder, not shown here, on the sensors 17 and 18 arranged at the end of the boom 16. The free end of the poster 19 to be rolled out of the poster drum 13 is fastened to the holder 2, which is arranged on the vertical support 15 of the inner cylinder 14, with a confectioning strip, not shown here. A securing device 27 provided for the clamping device 1 partially covers the bearing arms 5 and 6 underneath. With the aid of a ratchet, a defined pretensioning of the spring of the sensor 18 can be generated. The poster 20 is already unrolled from the poster drum 12 and placed on the inner cylinder 14. By pivoting the turnstile clockwise, the boom 16 unrolls the poster 19 from the poster drum 13 and rolls the poster 20 onto the poster drum 12. As can be seen from FIG. 2, in particular through the inventive design of the clamping device 1, preferably the choice of the distance between the axis 21 of the poster drums 12 and 13 to the contact surface of the inner cylinder 14, a defined placement and removal angle a and ß each formed between the contact surface of the inner cylinder 14 and the jacket of the poster drum 12 and 13 respectively. The angles a and ß are very small, preferably <25 °. The axis 21 of the poster drums 12 and 13 is always positioned parallel to the contact surface. This arrangement ensures that when the poster 19 is deposited, it is pressed evenly, directly and without an air cushion onto the contact surface. The air pressure presses the poster over the entire surface and without additional aids onto the contact surface of the inner cylinder 14 and holds it there. The small angle .beta. Enables the poster 20 to be detached continuously and tangentially from the contact surface of the inner cylinder 14 without difficulty when removed. A prerequisite for the described function of the advertising tower is a permanent prestressing of the poster drums 12 and 13, which on the one hand ensures that the poster 19 is rolled up and on the other hand gives the possibility of applying the poster 20 smoothly and directly to the contact surface of the inner cylinder 14 in a functionally reliable manner.

3 and 4 show the lower assembly of the advertising tower according to the invention.

As can be seen from FIG. 3, the support rollers 23 are mounted axially on the cover plate 22 and the guide rollers 24 are mounted with a vertical shaft. In addition, an electric motor 25 can be seen as a drive. For example, a friction wheel can be mounted on its shaft, which acts against the running surface of the base plate 26. The entire advertising tower built on the base plate 26 can thus carry out a continuous rotary movement with the corresponding running surfaces.

5 shows an advertising tower according to the invention built on a kiosk, the upper part of which is provided with a roof.

A particularly preferred embodiment of the invention provides for a film which is suitable for television recordings to be arranged on the surface of the outer cylinder. The film is preferably transparent. It has proven to be expedient to use an LED TV film for this. The advertising tower is therefore particularly suitable for operation at night.

A further preferred embodiment of the advertising tower according to the invention relates to the fact that, instead of the poster 19, a for television inspection lung suitable film is arranged on the inner cylinder, which is also preferably transparent. LED TV foils have also proven to be advantageous for this purpose. For example, they can be clamped, glued or clamped with suitable means and positioned in this way.
