Abstract

The two ends of the roller are increasingly thickened conically outwards. They both have applied sockets encompassing the thickness of the roller, which have conically increasing thickened formations to the roller ends. At least the roller surface between the applied sockets is smooth.

Description

The invention relates to a roller conveyor or roller blind who device for dynamic reproduction of image and / or Font information, with at least one finite or end loosely trained roller curtain that over at least one waa properly arranged, rotatable transport roller is guided, the part of the roll hanging from the transport roll following the curtain in the vertical direction is directed and spread. The invention further relates to a blank for the production of a roller blind.

Such a device can be found in EP 0 935 231 A2. In the known device, the dynamic presentati onseffekt on the relative movement of the two depending Limited sides of the roller blind. For a better dynami effect, several are placed side by side or behind mutually extending transport rollers with a corresponding Sufficient number of roller blinds used, for example se are attached to a common frame. Becomes  this device started, a multiple occurs Movement effect.

The object of the invention is to achieve the presentation effect increased dynamic of the image and / or written information for the generic type direction to improve without using multiple roller blinds to have to.

This object is achieved by a roll tape or Rollvor hang advertising device of the type mentioned, which is characterized by that

• - the roller blind is provided with internal cutouts,
• - And the image and / or font information on one with the inside of the transport roller to be contacted Roll curtain are applied so that the picture and / or Font information through the cutouts from the outside are visible and with a rolling curtain set in the aisle run against the direction of the cutouts.

The transport roller mounted in a housing becomes electrical driven, e.g. B. by a stepper motor, which is also in the Housing is installed, as is known per se.

The cutouts can be different on the roller blind be organized and have different sizes. In a simplest embodiment of the device can rollvor hang a single, relatively large section in the shape of z. B. a rectangle or a television screen be through which the on the inside of the roller blind brought image and / or font information from outside are visible.

The cutouts can also be across the width of the roller blind  be staggered in height and / or sides, so that a underlying advertising message - with a roll up or roll lumbar roller blind - can appear sequentially.

The roller blind can add additional picture and / or writing information Mations have, as usual, on its outside are applied so that two depressed advertising spaces for Ver stand by. If the device is put into operation, lukewarm pick up the advertising messages in opposite directions and give the impression that the process is double Speed. If the neckline is above one ren or lower vertex area is for a certain Time a look through a "half window" possible can also be used, a constant advertising message to send with half the picture height.

It is in the spirit of the invention the advertising space through which he to be able to better utilize high dynamics or new, additional che advertising space with an existing advertising device create. In addition, the front and / or is appropriate Back of the housing surrounding the transport roller with egg preferably a removable, paper or film-like one To equip advertising stripes. The printed one Stripes can e.g. B. from a self-adhesive, so-called Ab pull film exist on a smooth surface of the housing it can be stuck on. The strip can also be made from a magnet foil to be cut out on a suitable me adheres to the metallic housing.

It is advantageous to close the larger cutouts at their edges reinforce, for example with an adhesive tape or a ME tall or plastic profile. For larger ones, especially rectangular cutouts tend to have their transverse edges and corners for wrinkling, which negatively affects the ability to roll  is. It has been shown that the attachment of Me tall or plastic rails on the transverse edges the cutouts (with a normal paper or film thickness) prevents the buckling. With large cutouts is the attachment of metal or plastic rails up to to the respective outer edge, i.e. over the edge of the cutout tes necessary to prevent buckling. On the Metal or plastic rails are only dispensed with if the large cutouts each with a clear are covered with the transparent film section.

An exact off is important for correct operation direction and non-slip guidance of the roller blind. To this For this purpose, several measures are provided that create a harmonious Interaction of the moving parts.

First, the transport roller carries at both ends because a disk or egg protruding above the surface a collar. The roller blind has a width that is a little bit Length of the transport roll exceeds, so support practically with its edge areas on the two collars and lies on the surface of the transport roller.

Secondly, the transport roller has a smooth surface on that with the equally smooth inside of the roller blind contacted.

Third is the endlessly designed roller blind with one elongated dancer roll weighted, which also with the Inside of the roller blind is in contact. The dancer roll le preferably consists of a smooth, relatively light Pipe section, the two ends of which have a larger diameter than that of the rest of the pipe section and smooth rejuvenate. These measures ensure that the  running roller blind always centered and moved without slipping, although the contacting surfaces are smooth and have no mechanical drive parts, such as gears. Paradoxically, the weight of the rolling curtain alone secures and possibly the dancer role a little, but despite the sufficient frictional force at the contact point between the transport roller and the roller blind. In the present case no roughened surface of the transport roller is provided hen.

It is conceivable for the transport roller to have a similar external shape to lend, with their two ends towards Mit rejuvenate gently.

The invention further relates to a blank for Production of the roller blind, which consists of a rectangular Paper, textile or foil section from the mass up to 300 gr / qm, preferably 120 to 160 gr / sqm and from a thickness to 150 µm exists. A suitable material has, for example a hard PVC film up to 150 µm thick has proven itself with self-adhesive, thin posters or computer glue or print printed sections of paper or film Have screen or airbrush techniques labeled. The as Trä ger used paper webs should preferably have a maximum le mass up to 120 gr / sqm.

The blank is preferably with reinforcements arranged transversely Kungsschienen made of metal or plastic provided lengthways the transverse edges of the cutout (s) run. To do that Unraveling the long edges of the rolling curtain during the duration prevent operation, these are each with a thin Tape reinforced. The carrier material consists of a thin textile fabrics, such as polyester fabrics, can be longitudinal edge areas melted slightly together using the heat  be so that threads can no longer be pulled out.

Both the outer and the inner advertising space can be be lit. For illuminating the inside surface of the Roll curtain is proposed, at least one light source, like horizontal fluorescent tube, below the trans to accommodate.

The advertising device described can be placed in a standing or Mobile frame built in or on a single column le to be attached with a foot. An attachment to the ceiling or wall is also possible. Is the housing from a special light material, such as aluminum or plastic it can be practically self-adhesive on a window frame or attached to the inside of a shop window.

A compact advertising device that can be placed on a floor can be made of a transparent, tabular support and a preferred attached to the carrier or attachable wise stick-on housing, as well as with the roller blind and there belonging to transport and dancer roles. The Trä ger can be a rectangular sheet of glass placed in the foot recessed or otherwise connected to the foot is.

It is conceivable and technically feasible, relative to that to dispense with long housings in some cases. So it can Transport roller, for example, on two short elbows or the like can be stored, which is aligned horizontally attached to the window frame, preferably to the window frame are glued on. Furthermore, the respective window frame facing back of the two elbows with a single film or paper strips, possibly with picture and / or written information can be stuck on.  

A height-adjustable frame is not excluded position and / or to produce a variable-length housing, for example with telescopic and retractable and corresponding lockable parts.

The advertising device according to the invention can be different stalls or shelves can be combined.

In Figs. 1 and 2 is shown a roller blind Advertising device 100, which consists of an elongated housing 4, a housing in the Ge accommodated transport roller 6 and an endless roller curtain 2. The transport roller 4 is mounted at 29.1, 29.2 such that there is a distance A between the transport roller and the side walls 51.1 , 51.2 of the housing 4 (cf. FIG. 7). The housing 4 made of aluminum sheet is rectangular in its cross section shown in FIG. 2 and open at the bottom. The housing 4 also includes a built-in drive module 33 , which comprises a stepping motor, not shown, with a gear.

The roller curtain 2 guided over the transport roller 6 is made from a rectangular blank 1.1 , which consists of a 120 μm thick film section 40 and a paper poster ( FIG. 3a; partial section 26 ) lying on a (later) inside 5.1 of the roller curtain. The film section 40 consists of a 120 μm thick rigid PVC film. The paper poster is not connected to the film over the whole area, but rather via three transverse double-sided adhesive tapes 52 .

The blank has a large, rectangular cutout 3.1 and several circular cutouts 3.2 forming an oblique configuration. , , 3 .n on. The large cutout 3.1 takes up approximately 65% of the area of the roller blind 2 , which is delimited by two parallel reinforcing rails 21 and side edges 13.1 , 13.2 of the blank. The circular sections 3.2 . , , 3 .n have relatively small diameters and do not require any edge reinforcement. Image and / or writing information 10.1 is provided on section 26 using screen printing technology. , , 10 .n applied, their arrangement of the configuration of the cutouts 3.1 ; 3.2 . , , 3 .n corresponds. The outside 5.2 of the blank is also printed with image and / or font information 20 .

Fig. 3b shows a single-ply, ge made from a paper web blank 1.2 . The mass of the paper is 120 gr / sqm. The side edges 13.1 , 13.2 are each covered with a narrow reinforcement tape 23.1 , 23.2 ("TESA" tape ).

The cut 1.1 ; 1.2 is made into an endless roll curtain loop (roll curtain 2 ) by overlapping and gluing its narrow edges 25.1 , 25.2 .

A dancer roll 7 arranged at the lower end of the roller blind loop (in the assembled state of the advertising device) is widened at its two ends 8.1 , 8.2 so that the roller blind 2 rolling up and down is centered continuously. In the present case, the ends 8.1 , 8.2 of the dancer roll 7 form two rotational hyperboloids 32 , which can be seen in FIG. 10. In another embodiment, the dancer roll 7 has two truncated cones 31 (cf. FIG. 9) or two pushed-on, tapered end pieces 17.1 , 17.2 (cf. FIG. 11). The length of the dancer roll 7 is greater than the width of the roll curtain. Both the transport and dancer roll consist of thin-walled plastic tube and each have a smooth surface 9 .

As shown in FIG. 7, the width B of the roller blind 2 is somewhat larger than the total length L of the transport roller 6 . The transport roller 6 carries at its two ends a slightly projecting above the surface 9 collar 12.1 , 12.2 , on which the rolling and rolling roller curtain 2 is supported with its edge areas and between the abutting surfaces (side walls 51.1 , 51.2 ) along the Transport trolleys can move.

The dimensions of the roller blind advertising device 100 shown in FIGS. 1 and 2 are:
Height of the roller blind loop 140.0 cm,
Width of the roller blind 2 91.4 cm,
Width of the transport roller 6 86.0 cm,
Width of the dancer roll 7 96.4 cm,
Width of the case 4 106.0 cm.

The relatively small dimensions and design in light metal predestine the device 100 for use as a “roll-up and roll-off” advertising panel glued to the window frame 34 or directly to a window pane 46 (see FIG. 14 a). Since the housing 4 has a smooth front surface 36 , this can be pel adhesive tapes 35 , as shown in FIGS . 14 and 14a, with one or more commercially available double adhesive tapes ben. The adhesive force is sufficient for permanent mounting on the window frame or window pane. A double-sided adhesive tape is particularly well suited to a foam tape, so-called mirror tape, which is resistant to UV radiation, or a transparent double-sided tape, through which an advertising message brought up on the front of the housing is visible.

The device 100 is also provided for wall mounting with the aid of angle irons (not shown) with a tension screw or with the aid of screw connections. In all cases, the housing 4 should be aligned as precisely as possible. For this purpose, a water scale 24 is already installed in the housing 4 , as indicated in FIG. 1.

Fig. 8 shows a suspended on ceiling panels 22 advertising device according to the invention. On the housing 4 , two holes 31.1 , 37.2 are made , through which a steel cable 38 is pulled and attached to two so-called FISSO ceiling brackets 16 attached to the ceiling panels 22 . By pushing the housing gently on the steel cable, the advertising device can be quickly brought into balance.

In Fig. 4, the back of an advertising device 200 is Darge, in which the housing 4 is approximately semi-cylindrical ausgebil det and suspended via a centrally arranged mounting plate 39 on a single column 18 with foot 19 . The roll curtain loop has a height of around 200 cm and a width of 130 cm. The advertising device 200 can be placed on any flat surface, z. B. on the wall or window of an exhibition room or in the sales room.

A device 300 which can also be placed on a floor surface can be seen in FIG. 12. The rectangular housing 4 is part of a frame 15 . Two spars 41.1 , 41.2 made of an aluminum L-profile, on which the housing 4 is supported, and a robust, rectangular foot 49 ensure the stability and stability of the frame. In the rack 15 a lichtdurchläs SiGe safety glass pane 42 is also enclosed in such a way that it is with one of its narrow edge to the housing 4 detachable ver prevented, and inlaid with a second narrow edge in an incorporated at the base 49 groove 43rd

An arranged above the safety glass pane 42 upper surface 27.1 of the housing 4 is used for advertising purposes. The self-adhesive film strip 28 or film section 53 is attached to the surface 27.1 , as shown in detail in FIGS. 6 and 6a. A similar foil strip is attached to the back (surface 27.2 ) of the housing.

The film section 53 shown in FIG. 6a has only a narrow adhesive surface corresponding to the surface 27.1 of the housing and a large, rectangular cutout 14 through which the image and / or writing information applied to the roller blind 2 is visible. Through the cut out 14 is also the inner surface of the roller blind view bar, when the two cut-outs 14, cover 3.1. The area of the film section 53 corresponds to the entire area of a run of the roller blind.

In Fig. 5, a rectangular housing 4 is shown schematically made of sheet steel, on the surface 27.1 two rod-shaped ge magnetic elements 11.1 , 11.2 are applied, which carry a strip 47 made of magnetic film. The magnetic foil labeled with an advertising message can also adhere directly to the surface.

A special feature of the roller curtain 2 partially shown in FIG. 5 is that its large cutout 3.1 has no transverse reinforcement profiles. The whole section 3.1 is pasted over with a rectangular transparent film section 54 , so that no warping occurs during roll transport.

A further development of the advertising device 300 is a compact advertising device 400 shown in FIG. 13. A safety glass pane 42 is, as described in FIG. 12, left in a groove 43 of a double-T-shaped foot 48 and forms a carrier 45 for the housing 4 and other parts of the device. The housing 4 is simply attached to the carrier 45 with double-sided adhesive tape 44 . The safety disk 42 can also be made of other transparent, rigid panels, such as acrylic glass. The two advertising devices 300 ; 400 can be dismantled.

In Fig. 15 a double execution (reference numeral 500) is shown the advertising device 4 has two mutually parallel transport rollers are mounted in a correspondingly enlarged housing. The two roller blinds 2 can be started both synchronously and dependent on one another.

The advertising device according to the invention can basically in closed spaces, such as a sales hall, or outdoors if this is in a transparent out position boxes that withstand the weather can be accommodated. Use on vehicles and Trailers powered by solar panels is just if possible.

The preparation and function of the advertising device is explained in more detail below with reference to FIGS. 1 and 14.

A housing 4 is glued to a window frame 34 with a double adhesive tape 35 and aligned exactly horizontally.

After the "solidification time" specified by the manufacturer of the adhesive tape, a transport roller 6 is suspended in the housing 4 for testing, anchored and detached.

An endless roller blind 2 is produced from a blank 1.1 already described in FIG. 3a and placed on the transport roller 6 . After hanging the transport roller 6 in the housing 4 and inserting a dancer roller 7 into the roller blind loop, a short work test is carried out. After a possible correction of the storage and coupling of the transport roller to the motor, the device can be put into operation. After switching on the motor, the roller blind 2 runs at a speed of about 5 cm / s. Since the cut-outs 3.1 . , , 3 .n has, the image and / or writing information 10.1 applied to the inside 5.1 appear at certain time intervals. , , 10 .n and seem to run at twice the speed. This visual impression is additionally deepened by the image and / or writing information 20 applied to the outside 5.2 . The rolling up and down movement of the roller blind can of course be stopped if, for example, by the cutouts 3.1 . , , 3 .n visible advertising messages should have a "static" effect over a longer period of time. The process can be continuously controlled and also programmed. The control of the advertising device is not the subject of this invention and has been described, for example, in EP 0 935 231 by the applicant.
