The EP 1 449 188 B1 discloses a display device comprising a pair of elongate retainers extending along opposite sides of an imaginary rectangle, the retainers having respective longitudinal recesses holding respective edge portions of a poster, wherein at least one retainer of the pair comprises a stationary support member and a movable member containing the recess around an axis of rotation relative to the stationary one A support member from an active position in which the recess in a direction away from the opposite holding device is open, so that the poster in the vicinity of the edge portion turns on itself, wherein the poster is under tension between the pair of holding devices, in a passive position is rotatable, in which the tension in the poster is sufficiently released so that the edge portion of the recess of a holding device can be removed. Characteristic of this invention is that the stationary support element has a stationary end portion, an intermediate portion and a free end portion, the intermediate portion having a convex bearing surface, a portion of which is cylindrical, the free end portion having a cylindrical outer bearing surface coaxial with the cylindrical portion the convex bearing surface of the intermediate portion but of smaller diameter, the movable member having first and second longitudinal wings defining an open cavity therebetween for receiving the free end portion and the intermediate portion of the stationary bearing member, the first wing in the cavity a concave cylindrical bearing surface which fits the cylindrical outer bearing surface of the free end portion, wherein the first wing in a space between the free end portion and the intermediate portion of the stationary Auflageele is received when the movable member is in its passive position, and wherein the second wing in the cavity has a concave surface which fits the convex bearing surface of the intermediate portion, when the movable member is in its active position.

From the US 2006/0260211 A1 Furthermore, a clamping frame for a tarpaulin, in particular for mounting on a truck or truck trailer, on house walls and the like with a permanently mounted frame profile and an anchor profile is already known. In this invention, an anchor profile is provided which is connected by means of a spiral hinge with a fixed frame profile and by a defined angle relative to the Frame profile is formed pivotable. The anchor profile in turn is in the clamping state of the tarpaulin by a groove-claw connection with a clamping bracket into engagement, wherein the clamping bracket has at the end facing the tarpaulin a round cross-section Kederaufnahme. Characteristic of this solution is that basically three components are needed to form a tenter frame, namely the frame profile, the anchor profile connected thereto, and finally the tie bar with the anchor profile in engagement with the anchor profile.

The object of the invention is now to propose a locking device for receiving flexible advertising or decorative media, which can be used reliably even in adverse weather conditions, which is particularly easy to handle even by untrained personnel and which can be made cheap.

The FIGS. 1 to 3 show a cross section of a locking device 1 for receiving flexible advertising or decoration carriers 2, in particular posters, posters and screens, at least consisting of a first coupling partner 3 in the form of a substantially U-shaped rail, along the four edges, see Fig. 5 , an imaginary, the spanned surface of the advertising and decoration support 2 representing rectangle extending, wherein in the region of the first U-leg 3.1 inside a pan 3.2 and in the region of the second U-leg 3.3 a recess 3.4 for receiving at least one locking bolt 4 is placed , Further, a within the two U-legs 3.1, 3.3 of the first coupling partner 3 longitudinally extending complementary second, designed as a swing-wing rail second coupling partner 5 is provided, the first end 5.1 as one with the pan 3.2 of the first U-leg 3.1 of the first coupling partner. 3 formed in engaging ball 5.2, so that the second coupling partner 5 is pivotally mounted in the first coupling partner 3 and the second end 5.3 is formed as a latching nose 5.4, so that when latched locking pin 4, the second coupling partner 5 is temporarily locked at the second end 5.3 , And between the two ends 5.1, 5.3 of the second coupling partner 5 extending middle section 5.6 has both a cross-sectional flat Kederaufnahme 5.7 and a cross-sectionally round Kederaufnahme 5.8. In addition, the locking device 1 comprises the equipped with a round welt 6 and three flat springs 7 advertising and decoration carrier 2, each extending at its longitudinal edges, wherein in the final assembly position of the round welt 6 and the three flat piping 7 of the advertising and decoration carrier 2 in the formed into a rectangle corresponding Kederaufnahmen 5.7, 5.8 of the second coupling partner 5 and intervene for the purpose of mounting the advertising and decoration carrier 2 originally swung out, designed as locking lugs 5.4 second ends of the 5.3 second coupling partner 5 now engage behind the latched locking pin 4, whereby the advertising and decoration carrier 2 is subjected to tensile force and is tensioned accordingly. As a material for the two trained as longitudinal profiles two coupling partners 3, 5 aluminum was selected as an example.

The locking device 1 is facing the Fig. 5 arranged on a vertically extending Arretierungsvorrichtungsträger, wherein in Montageendposition the formed into a rectangle first coupling partner 3 are arranged such that in each case the pan 3.2 having U-legs 3.1 each face and thus in the interior of the spanned right-angled and the locking pin. 4 each receiving U-leg 3.3 have outward, and extending within the first coupling partners 3 and thus also formed into a rectangle second coupling partner 5 each outwardly in the direction of the locking lug 5.4 opening flat Kederaufnahme 5.7 have.

The Fig. 2 shows a cross section of the first coupling partner 3. The pivotable coupling connection by means of pan 3.2 and ball 5.2, see Fig. 3 provided pan 3.2 of the U-shaped rail extending first coupling partner 3 in the direction of its longitudinal axis is formed in the shape of a groove, wherein in the region of its two axial end faces in each case a releasable stop is provided to the second coupling partner 5 in its relative position relative to the first coupling partner 3 to lock. The upper side, respectively the side of the first coupling partner 3 facing the second coupling partner 5 in the final assembly position, comprises a marking 3.6 extending in the direction of its longitudinal axis for fastening elements in the form of screws 9 or rivets 9 for the purpose of mounting the locking device 1 on a locking device carrier. The bottom, respectively the mounting side, of the between the two U-legs 3.1, 3.3 of the first coupling partner 3 extending web 3.5, has at least partially a groove structure 10, which provides a sufficiently good primer for an adhesive bond between the first coupling partner 3 and the not shown Arretierungsvorrichtungsträger.

As the Fig. 3 clearly shows, the flat Kederaufnahme 5.7 of the second coupling partner 5 in the region of its opening a spherical opening edge 5.9, so that in this area, respectively the Kederfahne, folded advertising and decoration carrier 2 mechanically, for example, by abrasion, is not charged. In addition, extending from the round Kederaufnahme 5.8 distally an operating lever 5.5 for the purpose of manual pivoting by a user. In the final assembly state, ie in the locked state of the second coupling partner 5, the operating lever 5.5 extends over the latched locking pin 4, see FIG. 1 , whereby the locking pin 4 is no longer visible from the outside. With relaxed locking pin 4, however, this is about the outermost edge of the operating lever 5.5. The second coupling partner 5 has formed in its middle section 5.6 at the first coupling partner 3 in the final assembly position facing underside extending in the direction of its longitudinal axis Materialausnehmung 5.10. In the final assembly position, the marking 3.6 of the first coupling partner 3 and the material recess 5.10 of the second coupling partner 5 are directly opposite.

The Figures 4.1 and 4.2 each show a cross section of the same locking bolt 4 in two different positions. The first position corresponds to the relaxed state of the locking bolt 4 during assembly of the advertising and decoration carrier 2 on the locking device 1; the locking bolt 4 is therefore extended. In the second position, however, the locking pin 4 is engaged. When locking the locking pin 4 pushes in front of the locking lug 5.4 of the second coupling partner 5, whereby this is now locked on both sides. In this state, so if the second coupling partner 5 is placed in the first coupling partner 3 and the locking pin 4 is brought into its locking position, the final assembly state of the advertising and decoration carrier 2 is achieved at the locking device 1 and the example of a vehicle designed as a billboard advertising and decoration carrier 2 by means of its locking device 1 accordingly curious; excited. For completeness, it should be mentioned that not only a locking pin 4, but a plurality of locking pin 4 with a defined distance - designed according to static requirements - are used, which are placed on the first coupling partners 3 each on a common axis. To form a circumferential frame in the form of a rectangle, see Fig. 5 Accordingly, four first coupling partners 3, four corresponding second coupling partner 5 and approximately forty locking bolts 4 are required. All locking pins 4 are completely covered in the closed state by the operating lever 5.5 of the second coupling partner 5, that is visually not visible when viewed from the front. When opened, the locking bolts protrude approx. 3-4 mm behind the operating lever 5.5 to ensure better handling. Each locking pin 4 has therefore two positions: closed and open, being in the open position about 4 - 5mm longer and is locked by 90 ° rotation in the open position. With a new rotation by 90 ° of the locking pin 4 automatically engages under Federkraftbeaufschlagung in the closed position. When changing or replacing the advertising and decoration carrier 2, the user engages behind the operating lever 5.5. of the second coupling partner 5 and pulls on the / the locking pin 4. By the voltage of the advertising and decoration carrier 2, it pulls the second coupling partner 5 slightly outward, where it easily twists in itself. That is, for example, if six locking pins 4 are used for fixing the second coupling partner 5 on the first coupling partner 3, not all need to be solved / fixed simultaneously but one after the other. If the second coupling partner 5 is slightly pivoted, that is folded outwards and thus the locking pin 4 are easily accessible, the locking pin 4 are gradually opened, ie pulled out and fixed with 90 ° rotation in the open position. If the advertising and decoration carrier 2 has been threaded with his one round welt 6 and its three flat springs 7 in the second coupling partner 5, then the second coupling partner 5 is folded at one end and brought the advertising and decoration carrier 2 so under tension. The locking pin 4 are in the open state about 3-4 mm behind the operating lever 5.5 of the second coupling partner 5 forth and need only be slightly rotated and each rest. The manual engagement of the locking pin 4 takes place successively successively. The operation of opening and closing is very comfortable and easy for the user; At the same time, all locking pins 4 in the closed state are visually advantageously concealed by the operating lever 5.5. Basically, however, that only in the open state, the Flachkeder 7 can be removed from the associated flat Kederaufnahmen 5.7; in the closed state the Flachkeder 7 are each braced or jammed "and firmly connected to the second coupling partner 5, so not removable.

From the Fig. 5 is a front view of attached to a box body of a vehicle locking device 1 can be seen. As mentioned above, four first coupling partners 3, four corresponding second coupling partners 5 and approximately forty locking bolts 4 are therefore required. The formed into a rectangle rail-like first coupling partner 3 with its placed therein rail-like second coupling partners 5 form in the region of their joints, so in the four corners of the rectangle, each one covered by a triangular profile, not shown miter 8. By way of example, a backlit vertically extending box body of a vehicle is selected as the locking device carrier.
