Definitions

  • This invention relates to a device by means of which a tear-resistant film material, which is equipped at its edges with welt seams, can be stretched to form a wrinkle-free, membrane-like surface.
  • the invention further relates to various poster holders for setting up or building up posters made of tear-resistant film material, which can be constructed with the aid of such devices.
  • the foil material is primarily thought of sheets which are reinforced with textile fibers or a textile fabric.
  • the best known is truck tarpaulin material, which is available in different thicknesses and essentially includes a textile fabric that is coated on both sides with plastic.
  • Such tarpaulins are conventionally equipped with piping seams at their edges, which can then be inserted into suitable hollow profiles.
  • a tarpaulin is suspended from such a horizontally mounted hollow profile by inserting its piping into this hollow profile. If two opposite piping seams are inserted into such a hollow profile, the two hollow profiles can be in the transverse direction from each other be stretched away.
  • the object of the present invention is therefore to provide the simplest possible device which enables the tensioning of tear-resistant film material in such a way that one or more mutually angled, membrane-like smooth surfaces can be formed. It is a further object of the invention to provide special poster holders which can be constructed using these devices.
  • a device for tensioning tear-proof equipped with welt seams foil material, consisting of a guide element and a slidably guided thereon in the transverse direction to its direction, along the same at least one open on its long side hollow profile for receiving a welt hem of the film material to be tensioned, and with tensioning means for tensioning the profile transversely to its direction in the direction in which the hollow profile is located, the guide element being mountable at an oblique angle on a frame or a structure, so that the profile is obliquely angled in the direction of its direction is displaceable and tensionable to the tensioning direction of the film material to be tensioned.
  • a poster holder for holding posters made of tear-resistant film material equipped with welt seams which is characterized in that it has at least one device according to claim 1, which is mounted on a free-standing frame or itself a Chen forms or is mounted on a structure, so that the clamping profile in the transverse direction to its direction of movement can be shifted and tensioned at an oblique angle to the tensioning direction of the film material to be tensioned and the tensioning forces are only absorbed by the device itself.
  • the device is shown using an example and various uses of the device for tensioning film material, especially in the form of poster holders, are also shown.
  • the tensioning device is described in detail below with reference to these drawings and its function is explained. The various application options shown are commented on.
  • Figure 1 The device for tensioning two sheets at an angle to each other in the plan
  • Figure 2 An alternative embodiment of the device for tensioning two sheets at an angle to each other in the plan
  • Figure 3 A simplest version of the device for tensioning two sheets at an angle to each other in the plan
  • Figure 4 Four devices in cooperation for clamping a top and bottom open cube made of pieces of tarpaulin in the plan;
  • FIG. 5 the cube of tarpaulin surfaces spanned by means of four devices in an elevation
  • FIG. 6 The cube made of sheet surfaces spanned by means of four devices in a perspective view
  • Figure 7 A variant of a rectangular cube open at the top and bottom, the is constructed from four tensioned pieces of tarpaulin by means of four devices;
  • Figure 8 A variant of a prismatic body, open at the top and bottom, made up of three interacting devices and three pieces of tarpaulin connecting them in plan;
  • Figure 9 The variant of the prismatic body, open at the top and bottom in a perspective view
  • Figure 10 Three devices for clamping two pieces of tarpaulin around a wall or wall corner shown in the floor plan;
  • Figure 11 The variant with three devices, by means of which two pieces of tarpaulin which are at an angle to one another are stretched around a corner of the wall or wall, in a perspective view.
  • Figure 1 shows the device for tensioning two at an angle to each other sheets 19.20.
  • Two end pieces 21, 22 are inserted into two struts 1, 2 which converge towards one another and which here enclose an angle of 90 °.
  • a flat steel 3, 4 is welded onto the free ends of each of these end pieces 21, 22 at an angle of 45 ° to the respective strut 1, 2.
  • a guide element 5 is inserted between these two flat steels 3, 4.
  • This guide element 5 consists of two parallel flat steels 7, 8, which are welded to one another via a bridge 6.
  • the two flat steels 7, 8 are screwed to the flat steels 3,4 by means of three screws 9, 10, 11.
  • the two struts 1, 2 and the two end pieces 21, 22 are thus firmly connected at an angle of 90 ° to one another at a defined distance from one another.
  • an aluminum profile 12 is inserted, of which the cross section can be seen here.
  • a U-steel profile 13 is inserted into the aluminum profile 12 to reinforce it.
  • a square tube made of steel could just as well be inserted would be a bit more difficult, of course.
  • a hollow profile 14, 15 is formed along each of its two edges.
  • the aluminum profile is drawn directly with such a cross section during manufacture, so that these two hollow profiles 14, 15 are formed in one piece.
  • the piping 17, 18 of the adjacent sheet part 19, 20 is drawn into each hollow profile 14, 15.
  • the piping 17, 18 are attached in a conventional manner along the edges of the sheet pieces 19, 20.
  • a solid rubber profile with a circular cross-section or a string in the form of a wire or a wire strand is welded into a hem to form these piping.
  • the sheet pieces 19, 20 extend beyond the device from the drawing and so one does not see here that they are somehow firmly anchored there. This anchoring can be implemented in a similar manner by means of a welt hem which is inserted into the hollow profile of a permanently mounted aluminum profile.
  • the end pieces 21, 22 are longitudinally displaceable in the struts 1, 2, which at the same time act as spacer tubes, which extend over the length of the sheet piece 19, 20 to be tensioned in each case.
  • both end pieces 21, 22 are first moved out of the struts 1, 2 as far as possible by hand and then fixed by means of a screw 23, 24. With this, the pieces of tarpaulin 19, 20 are temporarily stretched. The actual full clamping now takes place in that the reinforced aluminum profile 12 is moved outwards in the direction of its front side 14, whereby it is guided between the two side walls 7, 8 of the guide element 5.
  • a nut 25 is welded onto the back of the bridge 6, in which a screw 26 is inserted.
  • this screw 26 has a hexagon head 27, so that it can be turned with a large torque using a wrench.
  • a different screw head would also be possible, for example with an Allen key.
  • alternative clamping devices can also be implemented.
  • a clamping lever with an eccentric can be pivotally mounted around the bridge so that the eccentric presses against the profile 12 when the clamping lever is folded. In this case, no tools are needed to tension or re-tension the sheet to solve.
  • the tarpaulin pieces 19, 20 held on the hollow profiles 15, 16 are tensioned.
  • the angular arrangement that is to say that the tensioning direction is at an angle of 45 ° to the plane of the tarpaulin, results in a force transmission.
  • the force F acting in the tensioning direction of the profile 12 causes a tensioning force of F / cos ⁇ at an angle to the plane of ⁇ of ⁇ .
  • the clamping force of the clamping profile 12 is therefore increased by a factor of 1.41 in the example shown.
  • a square steel tube 12 can be used instead of an aluminum profile 12 finished with hollow profiles, on which a profile rail with one or two hollow profiles 15, 16 along one narrow side Keder hems are screwed on, welded on, attached or otherwise applied.
  • the guide element 5 can also be made even simpler, as shown here, in that it consists of a U-shaped piece which is welded directly to the two end pieces 21, 22. The connecting leg of the U-piece forms the bridge, which is penetrated by the clamping screw 26 which acts on the square steel tube 12. The end pieces 21, 22 can then be inserted into spacer tubes of any length.
  • the profile 12 may even consist of only a square steel tube or square aluminum profile, which has a slot along its narrow side, so that it itself acts as a hollow profile.
  • the piping 17, 18 of the sheets 19, 20 to be tensioned can then simply be inserted into this slot, as shown here.
  • FIG 4 four devices as shown in Figure 1 are shown in cooperation for clamping four pieces of sheet 31-34.
  • the devices are connected to each other by square spacer tubes 1, 2, which act as struts between the individual devices.
  • the clamping profiles 12 each stand on a base foot 28 below. These base feet 28 can be screwed onto a solid floor, or they can also be concreted in or buried in an open field. In the latter case, however, they must be dimensioned larger and set so low that the canopy walls set up in this way are anchored in a storm-proof manner.
  • Figure 5 shows the cube spanned by means of four devices from tarpaulin surfaces in an elevation.
  • the four clamping profiles 12 extend from the base feet 28 to the upper edge 29 of the sheet pieces. You stretch these pieces of tarpaulin, of which only a single tarpaulin piece 33 sees enough of a membrane-like surface. The area inside the construction remains free and is open at the top and bottom.
  • clamping devices can be provided on two horizontal levels, but on several levels, which increases the clamping force accordingly.
  • FIG. 6 shows the tarpaulin cube made in this way, open at the top and bottom, in a perspective view.
  • a cube serves primarily as an advertising poster carrier and is in principle a poster holder.
  • the tarpaulin pieces 33, 34 can be printed directly with the advertising message and then drawn into the hollow profiles of the clamping profiles 12 with the piping seams at the side, after which the clamping profiles 12 are braced to the outside.
  • the reaction forces are absorbed by the struts or spacer tubes between the individual clamping devices.
  • the tarpaulin pieces on such a cube are so tightly stretched, and the transition surfaces from the tarpaulin pieces 33, 34 to the front sides 14 of the clamping profiles 12 are so smooth that the viewer is sure that the surfaces consist of metal or plastic plates.
  • the construction with pieces of tarpaulin is, however, much easier than if the same cube were made of metal or plastic plate.
  • the construction also has the advantage that the tarpaulin pieces are easily interchangeable and can be rolled for transport.
  • Such a cube can not only be used as an actual advertising medium, but is also suitable as a signpost, as a notice board, as a waymark or as a medium for one or more company logos. There are many other possible uses, which cannot all be listed here.
  • a waymark it can be used along hiking trails, whereby pictures can be printed on the pieces of tarpaulin, with explanations of the landscape or any peculiarities and sights that can be passed on this path.
  • company logos such a cube can be used game in front of the entrance to a company building so that you can recognize the company logo (s) from every side when you strive towards the entrance.
  • a poster holder can also be screwed to ceilings or walls by means of its base feet 28, so that it is thus mounted in a hanging manner.
  • Figure 7 shows the variant of an open at the top and bottom rectangular cube, which is constructed by means of four devices from four tensioned pieces of tarpaulin in the same way, the spacer tubes and tarpaulin pieces are simply longer in one direction than in the other direction.
  • Figure 8 shows three devices for building a prismatic body in a plan view.
  • the struts 1, 2 converge here so that they each enclose an angle of 60 ° instead of 90 °. Everything else remains the same.
  • the tension force ratio changes by calculating here for each side of a single piece of tarpaulin as follows, if F is the tension force with which the tension profile is pressed outwards: F / cos 30 °, that is, the tension force of the profiles is based on the angular relationships somewhat less, namely only with the factor 1.15.
  • Figure 9 shows the variant of the prism-shaped body open at the top and bottom in a perspective view.
  • this triangular shape is more storm-proof when it is set up outdoors, and it is particularly suitable for setting up on the side of roads and paths by placing it tip-up against the street or the path. In this way, those approaching on the street or path can see the side facing them at a pleasant angle.
  • Such a triangular body can, however, also be mounted on the ceiling in a hall, so that two clamping profiles 12 run horizontally along the ceiling and one runs offset to the bottom.
  • the devices for tensioning pieces of tarpaulin can be mounted in a variety of ways both inside buildings and outdoors, in order to mount pieces of tarpaulin or posters made of tarpaulin in any desired way.
  • Figure 10 shows a further variant of the use of this device as a poster holder.
  • three devices are used for clamping two pieces of tarpaulin 31, 32 around a wall or wall corner 30, which is shown in the figure in the plan.
  • the clamping devices 12 are screwed to the wall 30 by means of suitable flat steel brackets 35.
  • the individual devices are connected to spacer tubes 1, 2, in each of which an end piece 21, 22 is inserted at both ends in order to adapt the distance to the desired length of the tarpaulin piece.
  • the tarpaulin pieces 31, 32 are drawn from top to bottom with the piping of their side edges into the hollow profiles of the clamping profiles 12. Then the clamping profiles 12 are stretched outwards, which is done with the help of the clamping screws 26.
  • FIG 11 a variant with tensioned tarpaulin pieces mounted in this way around a wall or wall corner is shown in a perspective view, one tarpaulin piece being longer than the other.
  • Pieces of tarpaulin stretched around a corner of the wall or wall in this way offer a very clean and elegant sight because nothing of the tensioning device is visible.
  • Such a poster holder offers the advantage that the pieces of tarpaulin or the posters can be exchanged in a few simple steps and thus new advertising messages can be conveyed.
  • the reaction forces of the tension forces acting on the tarpaulin pieces are only absorbed by the spacer tubes and their end pieces and the wall or wall is in no way burdened with it. It only has to carry the devices and the sheet pieces, which are comparatively light.

Abstract

L'invention concerne un dispositif qui comprend un élément de guidage et un profilé guidé de manière à pouvoir coulisser sur ce dernier transversalement à son sens d'extension. Le long de ce profilé s'étendent deux profilés creux ouverts sur leur côté longitudinal, servant à recevoir chacun un bord, pourvu d'un bourrelet, du matériau de type feuille destiné à être tendu. Des moyens de contrainte servent à exercer une contrainte sur le profilé transversalement à sa direction d'extension, dans la direction où se trouvent les profilés creux. L'élément de guidage est monté de façon oblique sur un cadre ou une construction de sorte que le profilé puisse être déplacé et soumis à une contrainte dans le sens transversal à sa direction d'extension, de manière oblique par rapport à la direction de contrainte du matériau de type feuille destiné à être tendu. L'invention concerne également un porte-affiches présentant au moins un tel dispositif monté sur un cadre isolé ou formant lui-même un tel cadre ou bien monté sur une construction. Le profilé peut être déplacé et soumis à une contrainte dans le sens transversal à sa direction d'extension, de manière oblique par rapport à la direction de contrainte du matériau de type feuille destiné à être tendu. Les forces de contrainte sont absorbées uniquement par le dispositif lui-même.
