Definitions

  • the awning fabric is pretensioned in the longitudinal direction.
  • the degree of constriction depends on the ability to cross-contract and is, for example, relatively low for plasticized substances.
  • stretchable foils on the other hand, the constriction can become considerable, especially if there are pull-outs of several meters, as is the case, for example, with counter-pull awnings, which can have an extraordinarily large span.
  • the awning fabric deformed by the transverse contraction is wound up on the winding shaft, arises folds on the winding shaft, the longitudinal extent of which is essentially perpendicular to the axis of the winding shaft. Once these folds have arisen and are flattened by subsequent layers on the winding shaft, they are preserved and the longitudinal folds are created in the same way at the same point with each retraction and extension process. The result of this is chafing where the individual layers on the winding shaft become multilayered again due to the formation of folds. A late consequence of the chafe marks is a premature breakage of the awning fabric on the edges of the folds.
  • the transverse contraction in this area is brought to zero or at least greatly reduced.
  • a correspondingly reduced transverse contraction occurs, which prevents creasing when the awning fabric is wound up.
  • additional holding means are provided which hold the awning fabric and the strut together between the end fastening points.
  • the additional holding means enable the use of a strut which has only a very low bending stiffness. It it is sufficient if the strut can transmit sufficient pressure forces if it is guided laterally.
  • the strut need not be dimensioned in such a way that it acts as a reinforcement against a reduction in the sag. The flatter the strut, the smaller the radial deformation it causes in the winding.
  • the number of struts depends on the awning's projection and the cross-contracting ability of the awning fabric used. For example, with a counter-pull awning with a radius of six meters, a total of two struts, which are distributed equidistantly between the winding shaft and the extension bar, are sufficient to suppress any wrinkling.
  • the struts also do not protrude laterally over the awning fabric, but are flush with the edges of the awning fabric that is not stretched in the longitudinal direction.
  • Particularly weakly dimensioned struts which are just able to overcome the compressive forces that occur without compression, also have the advantage of low weight, which does not significantly increase the sag of the awning fabric in the longitudinal direction given the tension.
  • the material for the struts is metal, in particular light metal or plastic.
  • the holding means which, based on the longitudinal extension of the strut, hold the strut and the awning fabric together, can be formed by a multiplicity of equidistantly distributed adhesive locations, continuous gluing of the strut on the awning fabric, which is untensioned in the longitudinal direction, or else by a tubular loop in which the strut is loosely housed or in which it is glued to the awning fabric.
  • a tight fit of the strut in the loop should be ensured, so that an arcuate deformation of the strut compared to that in the width direction taut awning fabric is avoided, which could otherwise nullify the effect of the strut in the sense of suppressing the transverse contraction.
  • the strut or struts reduce the formation of wrinkles that otherwise occurs when the awning fabric that is pretensioned in the longitudinal direction runs onto the bales of the winding shaft because, because of the change in the then effective tension in the longitudinal direction, there is apparently too much material in the transverse direction, whereby the longitudinal fold in question arches continuously upwards on the wrap. Since the length of this fold, seen in the longitudinal direction, can make up more than one revolution of the winding shaft, there are different length ratios on the apex of the arched fold than in the position in question, which causes the undesirable abrasive movements leading to premature wear.
  • a counter-pull awning 1 for shading a glass roof 2 of a glazed veranada or a glass stem 3 is illustrated.
  • the counter-pull awning 1 contains two parallel guide rails 4 which are spaced apart from one another and which are connected to the glass roof 2 by supports 5 near their ends.
  • end shields are positively attached.
  • a cloth or awning web 11 which is visible in the extended state in FIG. 1 is fastened with its rear edge to the winding shaft 8, while its front edge is connected to an extension rod 12 which for this purpose contains an undercut groove 13 which is continuous in the longitudinal direction.
  • the pull-out rod 12 is fastened at its two ends to an associated guide slide 14, which runs in a corresponding groove 15 of the associated guide rail 4.
  • the awning 1 is extended, as is customary in the case of counter-pull awnings, with the aid of traction means, not illustrated, which run through or in the guide rails 4 and, at the same time as the winding shaft 8 rotates, pull the slides 14 through the guide rails 4 to the fabric web 11 to keep excited in any position.
  • the two end shields 7 are essentially flat structures and have the shape shown in FIG. 2. They are provided with bearing seats (not recognizable in the figures) for receiving winding shaft bearings. Furthermore, the bearing plate 7 carries an extension (not recognizable in FIG. 2) which is inserted in a corresponding opening in the associated guide rail 4 around the guide rail 4 on the bearing plate 17 to fix.
  • the fabric web 11 forms a fabric bale 19 on the winding shaft 8.
  • the hood 9 which can be seen in cross section, is located above the winding shaft 8.
  • the hood 9 is made of a strut 21 rotatably held, which extends between the two end plates 7.
  • two struts 22 running parallel to the pull-out rod 12 are provided with the awning fabric 11.
  • the two struts 22 have a width which corresponds exactly to the width of the fabric web 11 which is untensioned in the longitudinal direction, so that they do not protrude outwards. Over their entire length, these struts 22 are glued flat to the fabric web 11, so that in the area of the struts 22 a transverse contraction of the fabric web 11 is prevented, which is caused by the tensile stress that initiates the countertraction device in the fabric web 11 in the longitudinal direction.
  • the struts 22 consist, for example, of an approximately 4 mm thick and 25 mm wide aluminum flat profile and are fastened with the flat side to the top of the fabric web 11. The consequence of this is that, apart from the compressive force acting in the longitudinal direction of the struts 22, they produce almost no stiffening in the vertical direction, for example to reduce the sag.
  • the two struts 22, based on the fully extended state of the fabric web, are distributed equidistantly between the winding shaft 8 and the pull-out rod.
  • FIG. 3 shows another form of connection of the strut 22 to the awning fabric 11.
  • the awning fabric 11 then consists of transverse webs 23 and 24, which have a length corresponding to the width of the finished fabric web 11.
  • the two transverse tracks 23 and 24 are connected to one another in an overlapping manner in a region 25 that extends over the width.
  • the connection consists, for example, in two mutually spaced double seams 26, between which a tubular pocket or loop 27 is created.
  • the strut 22 in question is inserted as tightly as possible and without play into this tubular pocket 27.
  • the length of the strut 22 is in turn dimensioned as described above.
  • the strut 22 only needs to be glued to the ends with one of the two transverse webs 23, 24 or it can be glued to both transverse webs 23, 24.
  • the tubular pocket 27 prevents the middle region from buckling upwards or downwards as a result of the pressure forces arising from the prevented transverse contraction.
  • the tubular pocket 27 thus acts as a holding means to hold the strut 22 and the sheet 11 together.
  • the design with pocket 27 has the advantage that the strut 22 is not visible from above or below. Rather, it is covered on both sides by the material of the sheet 11.
  • the strut 22 Since the strut 22 only has to absorb pressure forces in the direction of its longitudinal axis, it can be made comparatively very thin. In particular, it can be kept very thin if it is glued to the fabric web 11 over the entire length.
  • the number of struts 22 used depends on the length over which the awning 1 is to be extended. As a rule, depending on the material, struts 22 at a distance of approximately 1.5 m or more are sufficient to avoid undesired wrinkling.
  • the counter-pull awning 1 shown is only one example of the use of the struts 22 in awnings in which a longitudinal tension is generated in the fabric web 11 by a pretensioning device in the form of the counter-pulling device.
  • Another design of awnings with considerable tensile force in the longitudinal direction of the fabric sheet 11 are, for example, articulated arm awnings.
  • one or more struts 22 prevent undesired cross-contraction, with the result that wrinkles form on the cloth bale 19.
