Definitions

  • an awning with a counter-pulling device which has two parallel guide rail arrangements, in which the supporting rods (bow) for the awning cloth and the pull rod attached to the front edge of the awning cloth are guided.
  • Each of the guide rail arrangements consists of straight guide rail pieces which are connected to one another via curved pieces.
  • the arc pieces themselves consist of individual straight sections, which have the same profile as the guide rails and in which the flat end faces converge, the angle which each end face encloses with the longitudinal axis of the section being equal to one another. In this way, the arc between two straight guide rail pieces is approximated by a polygon made up of short, straight pieces which lie against one another without joints.
  • a central, continuous chamber is provided in the profile, in which connecting elements sit, which are hinged to one another via hinge bolts.
  • the hinge axis runs in the joint between adjacent sections or between the curved piece and the adjacent guide rail.
  • the angle between two guide rails connected to one another via an arc piece can only be adjusted in steps according to the convergence angle of a section. Angles in between cannot be realized in this way without special machining operations on the end faces of the guide rail or of the section. It is therefore not always possible to ensure that the guide rails in the known solution run exactly parallel to the outer contour of the glass stem, for the shading of which the awning is provided. In particular, it is not possible to compensate for smaller tolerances on the construction site, which are always unavoidable in the manufacture of glass stems. The result is an unsatisfactory appearance if the guide rails do not run exactly parallel to the contour of the stem.
  • the profile of the guide rails is sensitive to contamination because all the chambers in which the traction means of the counter-pulling device and the pull rod are guided open to the side of the profile and, moreover, the grooves thus formed have a T-shaped cross section, which is what leads to the accumulation of dirt precisely in the at least approximately horizontally running sections of the guide rail arrangement. This dirt causes premature closure and stiffness.
  • the traction means can freeze due to the design of the chambers in which they run.
  • each arch piece from at least two or more arch elements, the angle between guide rails connected to one another via the arch piece can initially be roughly achieved by adding or omitting individual arch elements. For example, rough adjustments of approximately 8 to 15 ° are possible in this way if the end faces of an arch element are inclined towards one another by approximately this amount.
  • connection between the arch elements is mechanically very simple and robust at the same time if the cross-sectional profile has a web and at least one flange formed on the web and the hinge is formed in the region of the web.
  • the gap widths occurring in the extreme positions become particularly small if the hinge axis lies approximately in the middle, based on the vertical extent of the cross-sectional profile.
  • the web set back next to and opposite the tab contains a recess which springs back from the front side and whose depth, measured in the direction perpendicular to the web is equal to half its wall thickness, such that the tab of an arch element is to be received in the recess of the adjacent arch element, only one embodiment is required for those arch elements which do not abut guide rails elsewhere.
  • Special manufacturing tools are only required for such arch elements in order to produce the connection to the guide rail in a simple manner. This can be done, for example, by means of pins which are inserted into corresponding chambers of the arch element or are integrally cast onto the arch element.
  • a penetration of dirt into the parting line between adjacent arch elements can be very effectively prevented if the flange of the cross-sectional profile has a roof projecting over the end face on one end face, while a recess is provided on the end face of the adjacent arch element or on the other end face of the same arch element is such that, in the case of adjacent arch elements, the roof of one arch element engages over the recess in the flange of the other arch element, in such a way that the roof edge preferably points downward. This gives the entire bow a look similar to a lobster tail.
  • a penetration of dirt and water into the chambers, in which the traction means of the counter-pulling device and the pulling rail are guided, can be achieved if side flanges leading downward from the flange are provided, in which open grooves are contained towards the web, in which the Traction devices and the guide rail run.
  • the cross-sectional profile of the guide rail is therefore only open at the bottom with a horizontal course, which effectively prevents rainwater from penetrating.
  • FIG. 1 schematically shows a building 1, in front of the side wall 2 of which a glass stem 3 is provided.
  • the glass stem 3 is closed at its top by a roof 4, which merges into a vertically extending end wall 5 on its side remote from the building wall 2.
  • both the roof 4 and the end wall 5 can be shaded from sunlight.
  • Fig. 1 the two awnings are illustrated in the extended state.
  • Each of the two identical awnings 6, each equipped with a counter-pulling device, has an awning box 7 running next to the building wall 2, in each of which a winding shaft is rotatably mounted.
  • the awning fabric 8 in question is attached to the winding shaft with an edge, the edge of which is to be extended is attached to a pulling rail 9.
  • the two awning boxes 7 are the winding and length compensation devices, as are customary and known for balancing awnings.
  • a guide rail arrangement comprising a total of three guide rails 11a, 11b and 11c is provided, the guide rail arrangement 11b being common to both awnings 6.
  • Each of these mutually identical or mirror-image guide rail arrangements 11a ... 11c consists of an upper guide rail 12 which is raised on the roof 4 by means of roof stands 13 in such a way that it runs parallel to the roof 4.
  • Each guide rail arrangement 11a ... 11c has a further guide rail 14 which begins just below the roof 4 and runs parallel and vertically downwards in front of the end wall 5.
  • the guide rail 14 is also anchored to the glass stem 3 with the aid of stands 15, specifically on its end wall 5.
  • each guide rail arrangement 11a ... 11c contains an arc piece 16 which runs over the edge at which the roof 4 merges into the end wall 5.
  • These arc pieces 16 are also identical to one another and have the task of guiding the pull rail 9 or the bow and the pulling means from the guide rail 12 into the guide rail 14.
  • the arc piece 16 is illustrated in Fig. 2 enlarged.
  • the bow piece 16 Seen from the outside, the bow piece 16 resembles a lobster tail and consists of a total of six middle bow elements 17 which are identical to one another and two end bow elements 18 and 19 which produce the connection between the middle bow elements 17 and the guide rails 12 and 14, respectively.
  • Two of the middle arch elements 17 are illustrated in perspective in FIG. 3, being separated from one another at their connection point and being rotated differently, so that the front and one back of the arch element 17 can be seen on one of the arch elements 17. Since the arch elements 17, as mentioned above, are exactly the same as one another, no distinction is made in the following explanation of FIG. 3 between the two sheet elements 17.
  • each arch element 17 like the rest of each guide rail 12, 14, has an essentially T-shaped shape at its core, which is composed of an approximately vertically extending web 21 and a flange 22 extending transversely above it.
  • This continuously constant cross-sectional shape extends from one end face 23 to one end face 24, which are adjacent to one another in the case of adjacent arch elements 17.
  • the flange 22 is formed with a hollow chamber 25 which is continuous from the end face 23 to the end face 24 and is delimited at the top by a convexly curved roof 26, the axis of curvature of the roof 26 being in the longitudinal direction of the arch element 17.
  • the longitudinal direction is understood to mean the direction in which the pulling rail 9 moves when the awning fabric 8 is moved in and out through the relevant arch element 17.
  • the web 21 is laterally delimited by two mutually parallel flat side surfaces 27 and 28 and essentially extends from one end face 23 to the other end face 24.
  • the web 21 On both end faces 23 and 24, the web 21 has a semicircular curve in the side view Tab 29 or 31 in front. Their center of curvature is either on the surface of the relevant end face 23, 24 or slightly outside.
  • the thickness of the tab 29, measured in the direction perpendicular to the side surfaces 27 and 28, is half the thickness of the flange 21 otherwise. The same applies to the tab 31.
  • the tabs 28 and 31 are mutually on one and the same arch element 17 arranged with respect to a vertical plane which runs centrally between the side walls 27 and 28, ie the tab 31 is in a plan view of the end face 23 to the right and thus in the extension of the side wall 27, while the tab 29 is arranged to the left of the vertical plane and thus adjoins the side wall 28 when the viewing direction is unchanged.
  • the web 21 contains a recess 32 which is open towards the end face 23 and towards the side wall 28 and whose contour is exactly the same as that of a recess 33 laterally next to the tab 29.
  • the recesses 32 and 33 can be seen in Floor plan approximately quarter-circular and open to the underside of the web 21 in order to facilitate production. In any case, they are dimensioned such that when the two arch elements 17 adjoin one another with their end faces 23 and 24, the tab 31 can penetrate into the recess 33 and the tab 29 into the recess 32 so that the tabs 29 and 31 can form a hinge whose axis is perpendicular to the side wall 27 or 28 of the web.
  • the hinge pin of the hinge formed in this way is a countersunk screw 34 which leads through a conically countersunk bore 35 in the bracket 31 and a flat-countersunk bore 36 in the bracket 29.
  • the axes of these bores 35 and 36 coincide with the centers of curvature of the tabs 29 and 31.
  • the diameter of the countersink is chosen so that the nut 37 is pressed in, so that it cannot turn when the screw 34 is tightened.
  • the dimensions in the area of the tabs 29 and 31 or the recesses 32 and 33 are chosen such that when the arch elements 17 are joined together, the side walls 27 of the two arch elements 17 and the side walls 28 are smooth and without projections, neither by screw heads still interrupted by nuts, so that no leading parts of the pull rail 9 can get caught or generate noise.
  • two approximately plate-shaped side walls 38 and 39 are provided, which merge integrally into the flange 22 and lead from there downward, their lower edge 42 being lower than the underside of the web 21.
  • the web 21 thus jumps opposite the side walls 38 and 39 back upwards.
  • the side walls 38 and 39 are mirror-symmetrical to one another, so that one and the same arch element 17 can be used both on the left and on the right side of the awning fabric and also for row systems, as shown in FIG. 1, for the middle guide rail arrangement 11b Can be found.
  • the side cheek 38 Adjacent to the lower edge 42, the side cheek 38 carries a rib 43 projecting onto the opposite side cheek 30, which is approximately rectangular in cross-section and which contains in its interior a passage 44 which is rectangular in cross-section and which completely penetrates the rib 43 in the longitudinal direction and on both end faces 23 and 24 is open.
  • a corresponding rib 43 is also provided on the side cheek 39, a corresponding passage 44 being contained in the rib 43.
  • a narrow ledge 45 upwards, such that there is an upwardly open groove with the inside of the side cheek 38 or 39 in question, the bottom of the groove 46 in the longitudinal direction of the Arch element 17 extends.
  • small grooves 47 are contained in the strip 45 and opposite in the relevant side cheek 38, 39, which are open towards each other and serve to hold a small rectangular plastic plate 48, which consists, for example, of PTFE or polyamide, and in serves to reduce friction described below.
  • Similar grooves 49 are present in the passage 44 and serve to fix another friction-reducing plate 51; Both plates 48 and 51 extend from one end face 23 to the other end face 24 in the inserted state.
  • the two plates 48 and 51 are provided on their underside with small projections or noses 50, with which they fit into corresponding recesses in the groove base 46 and 49 must be anchored so that they can be easily replaced in the event of wear.
  • plastic plates 48 and 51 for example produced as a molded part, are slightly cambered in the longitudinal direction on the upper side, as shown, the axis of curvature being transverse to the running direction of the traction means. This is intended to ensure that, although for reasons of simplicity of manufacture, the groove bases 46 and 49 run straight, there is a curved sliding surface for the traction means, which corresponds approximately to the radius of curvature of the entire arc piece 16.
  • the roof 26 on the front side 23 contains an upward recess or fold 52 which continues into the two side walls 38 and 39.
  • the fold 52 cooperates with a joined sheet elements 17 with a downwardly open fold or recess 53 on the other end face 24.
  • the remaining part 54 of the recess 53 forms a roof overlapping the fold 52 more or less far in the assembled state.
  • the side cheeks 38 and 39 are aligned with the bores 35 and 36 at the end face 23, thus aligned eyelets 55, with which semicircular recesses 56 on the opposite side 24 correspond.
  • the arch elements 18 and 19 located at the end of the arch piece 16 differ on one end face in each case from the above-described middle arch elements 17 according to FIG. 3.
  • the arch element 18, as shown in FIG. 2 corresponds to the arch element 17, beginning starting from the end face 24, that is to say the right part of the arch element 17, while on the left side the arch element 17 would be cut off smoothly and there carry two plug pins 57 and 58 which are rectangular in cross section and which are integral with the arch element 18.
  • the insertion pin 58 extends in the extension of the web 21, while the insertion pin 57 is arranged in the extension of the flange 22. With these two plug-in pins 57 and 58, provided in the guide rail 12 aligned chambers, which over the entire length of the Pass through the guide rail 12. Otherwise, the cross-sectional profile of the guide rail 12 corresponds to the explained profile of the arch elements 17.
  • the assembly and use of the arc piece 16 described so far is as follows: If the angle between the guide rails 12 and 14 is very obtuse, for example between 180 and 170 o , it is sufficient if the two end-side arch elements 18 and 19 are connected directly to one another.
  • the design of the two end faces 23 and 24 is such that the guide rails 12 and 14 can be angled approximately in an angular range between 180 and 170 o , the movement being made possible by the hinge from the tabs 29, 31 and the screw 34 . Only in these two end positions do parts of the end faces 23 and 24 of the immediately adjacent arch elements 18 and 19 abut one another. In between, free mobility is possible.
  • the roof 54 overlaps the fold 52, so that rain cannot penetrate either from above or from the side.
  • the eyelet 55 lies in the adjacent recess 56, so that the side cheeks 38, 39, apart from the openings in the eyelets 55, are largely closed.
  • the bow piece 16 prepared to this extent which in this case only consists of the two end bow elements 18 and 19, is inserted with its insertion pins 57 and 58 into both the guide rail 12 and the guide rail 14 and there by means of screws 59 screwed into the insertion pin 57 axially secured.
  • the screw 34 is tightened and the hinge formed by it is thus clamped.
  • the traction means common to retractable awnings can be retracted, whereby the working strand, which engages on a carriage of the pulling rail 9, slides on the groove base 46 or the plastic sliding piece 48 placed thereon, while the returning strand, i.e.
  • the plastic insert 51 serves to reduce the friction and thus to improve the service life of the traction means, which are formed, for example, by a steel band.
  • the carriage for the pull rail 9, on the other hand, runs with its rollers in the space between the groove base 46 and the region of the flange 22 above it, the support elements which connect the pull rail 9 to these rollers, from below, through between the ribs 44 and lead the gap 21 formed therein.
  • the two terminal arch elements 18 and 19 are no longer directly connected to one another, as described above, but rather one becomes more according to the desired angle or less large number of middle arch elements 17 inserted.
  • a total of six middle arch elements 17 are required for the selected dimensions in order to realize an angle of 90 ° between the two guide rails 12 and 14, the arch elements 17, 18, 19 then being in the region in the maximum kinked position their lower portions of the end faces 23 and 24 abut each other.
  • the curved piece 16 assembled according to FIG. 2 can be stretched in the other extreme position to an angle of 10 ° between the two guide rails 12 and 14.
