Definitions

  • the invention relates to a vertical awning or awning isolette with the features of the preamble of claim 1.
  • a Markisolette which has two stationary guide rails next to a window, in each of which a slide is guided vertically.
  • the two slides running in the guide rails are connected to one another by an axis on which a deflection roller for the awning track is rotatably mounted.
  • a drop arm is pivotably pivoted about a horizontal axis below the deflection roller which extends over the entire window width.
  • the distance of the articulation of the drop arms from the deflection roller corresponds to the length of the drop arms, so that the drop arms can directly contact the associated slide when the awning is trapped.
  • the drop bar is attached to the free front edges of the two extension arms, to which the front edge of the awning cover is attached.
  • the two carriages in the guide rails first move downwards, causing the awning cover to be in front of the corresponding window is pulled down vertically, similar to a roller blind.
  • the carriages hit stops arranged in the guide rails the carriages stop and when the awning fabric is further unwound from the winding shaft, the extension arms begin to swivel down and spread the awning fabric away from the window. The deflection takes place on the deflection roller.
  • At least one of the slides can be locked in at least one lower position, with no additional aids for controlling the transmission being required than the movement of the awning itself.
  • An awning equipped with this gear can be lowered from the rest position into the desired locking position and is locked over a relatively small distance by subsequent retraction. If a gust of wind gets caught under the awning cover, the carriage will be held securely in the lower position.
  • the awning cover can only inflate according to its own elasticity, but this does not lead to any significant balloon formation.
  • the locking mechanism consists of a part attached to the slide and a part fixedly attached to the associated guide rail, the guide grooves, which correspond to the conditions, forming a heart curve into which the scanning element engages the connection point of the guideway belonging to the first and the third state runs into the heart curve or runs out of the heart curve.
  • the saddle in the third curved track corresponds to the locked position.
  • the arrangement can be such that the heart curve is formed on the guide carriage and the scanning member on the guide rail and vice versa with a heart curve provided on the guide rail and the scanning member attached to the guide carriage.
  • a particularly effective safeguard which avoids the awning from being pulled in the event of gusts of wind, is to provide a detent mechanism in each of the two guide carriages, which are aligned with one another and each rest at the same height position of the awning.
  • the detent gear can be combined with a gearwheel in such a way that one part of the detent gear sits in a gearwheel which is rotated by the actuation of the awning while the other part of the locking mechanism is housed in the carriage.
  • a structurally very simple arrangement that is safe against contamination is obtained if the cam tracks are formed on a sleeve which is arranged in the carriage in a rotationally fixed and displaceable manner and which at the same time forms the bearing axis for the gearwheel in which the scanning pin is guided in a radially displaceable manner.
  • the gear can be locked immediately.
  • the locking takes place with the aid of a slide which is controlled by the latching gear and which interacts with a corresponding stop.
  • the locking mechanism in the area of the slide of the vertical awning in order to fix the slide at the desired height.
  • the locking mechanism can also be accommodated in the box at the winding shaft, which gives the advantage of better protection against contamination.
  • the carriage is blocked with the aid of one or more locking members which are longitudinally displaceable or rotatable in the guide rail and are controlled by the latching mechanism.
  • the use of two locking members has the advantage of fixing the slide on both sides, the actuation of the two locking members being effected either by two latching gears, each of which is assigned to a locking member, or in which a gear member is arranged parallel to the winding shaft in order to synchronize to co-operate with the one locking member the other locking member.
  • a vertical awning 1 which has two bearings 3 and 4 attached to a wall or facade above a window 2 for the rotatable mounting of a winding shaft 6 rotatable about a horizontal axis 5, on the rear edge of which an awning sheet or an awning fabric 7 is attached.
  • a drive device not further illustrated, for example a known tubular motor
  • the winding shaft 6 can be set in revolutions in the sense of winding up or unwinding the awning fabric.
  • the front edge of the awning fabric 7 is connected to a drop bar 8 on which two guide carriages 9, which are identical to one another, are seated at the ends.
  • the two guide carriages 9, which are mirror images of one another, run in two parallel and vertically arranged guide rails 11 and 12, which are fastened at their upper end in brackets 13 and 14 and at their lower end in brackets 15 and 16 are.
  • the structure of the guide carriages 9 and of the guide rails 11 and 12 can be seen from FIG. 2, which also shows that both guide carriages 9 are provided with a cam-controlled indexing gear 17.
  • the mutually identical guide rails 11 and 12 each have the shape of a cylindrical tube which has two longitudinally continuous slots 18 and 19 on two diametrically opposite sides, which divide the jacket of the tube into two semi-cylindrical shells 21 and 22.
  • the two partially cylindrical shells 21 and 22 are integrally connected to one another by a central web 23, which also extends over the entire length.
  • Each of the guide carriages 9 consists of a base or frame plate 24, which has a lower and an upper narrower section 25 and 26, respectively.
  • two rollers 27 and 28 are mounted at a distance from one another so as to be rotatable about axes that run horizontally parallel to one another.
  • the guide rollers 27 and 28 each have a deep groove 29 and 31 running in the circumferential direction, the diameter at the bottom of the groove being smaller than the width of the slot 18 and 19 respectively.
  • the rollers 27 and 28 are formed Cheeks, one of which runs inside the guide rail 11 or 12 and the other outside. In this way, the guide carriage 9 is guided vertically in the corresponding slot 18 or 19 and is secured both against tilting about a horizontal axis and against being pulled out of the associated guide rail 11, 12.
  • the lower section 25 of the base plate 24 contains a part 32 of the locking gear 17, while the other part of the locking gear 33 is fixedly attached to the associated guide rail 11, 12 at the height at which the awning 1 is to be locked in the extended position.
  • the part 32 of the locking mechanism 17 located in the lower section 25 consists of a series of grooves and recesses with the course explained below.
  • an underside 33 of section 25 has an approximately triangular plan and in the direction of the underside 33 and in the direction of the guide rail 11 open recess 34 which tapers in the direction of the upper section 26 without changing its depth.
  • the narrowest point reaches the recess 34 at 35, from where two guide grooves or guideways 36, 37 extend, which have the same depth as the recess 34, and starting from the point 35 initially diverge upwards.
  • the two upwardly-extending guide grooves 36 and 37 are connected to one another by a guide groove 38 which is approximately transverse to it and downwardly sagging.
  • a kind of heart curve is created in this way, a central piece 39 being delimited by the guide grooves 36, 37 and 38 and containing a depression 42 on its upward-facing surface 41.
  • the recess 42 is approximately opposite a downward extension 43 of the transverse guide track 38.
  • the guideways 36, 37 and 38 have a clear manner such that a pin 44 inserted via the inlet recess 34, the longitudinal axis of which is perpendicular to the base of the groove, passes through the guide grooves 36, 37 and 38 and runs out again through the inlet recess 34 can.
  • This guide or scanning pin 44 belongs to the fixed second part of the latching gear 17 and is located at the upper end of a one-armed lever 45, which is pivotally mounted at the other end in a bearing block 46 about a horizontal axis 47.
  • the mounting of the lever 45 is stiff in such a way that the lever 45 maintains the position into which it is pivoted and cannot be adjusted by gravity.
  • the bearing block 46 contains, below the axis of rotation 47 of the lever 45, a bore 48 for a fastening screw 49, with the aid of which a T-slot nut 51 serving as a nut and seated in the guide rail 11 can be screwed tight.
  • the operation of the awning 1 described so far is as follows: if, starting from the fully retracted state, the awning fabric 7 is unwound from it by starting the winding shaft 6, the front edge of the awning fabric 7 moves together with the drop bar 8 and the two on it laterally seated guide carriage 9 vertically downward, the guide carriage 9 being mounted in the guide rails 11 and 12. As soon as the awning 1 is lowered far enough, the funnel-shaped inlet recess 34 of each guide slide 9 comes into engagement with the guide pin 44. As a result of the tapering of the inlet recess 34 in the direction of the point 35, the corresponding lever 45 is brought into the position defined by the taper at 35.
  • the lever 45 is pivoted more or less back by the guide pin 44 running through the guide groove 38 in the direction of the starting position.
  • the two guide carriages 9 have reached their lowest possible position when the awning 1 is extended. If the awning fabric 7 were to be unwound further, it would begin to hang limply over the drop bar 8, because the two guide carriages 9 stand on the associated guide pins 44, which are at the same height.
  • the winding shaft 6 is rotated in the opposite direction in the sense of a winding or opening of the awning fabric 7, whereby the guide carriage 9 resting on the pin 44 is raised.
  • the corresponding guide pin 44 comes into engagement with the lower flank of the transverse guide groove 38.
  • the lower flank of the guide groove 38 is formed by the middle piece 39, which contains the recess 42, which is why the guide pin 44 is guided into the recess 42.
  • the lifting of the drop bar 8 can also be achieved in that the awning fabric is unwound above the bottom dead center, so that it is wound onto the winding shaft 6 again with the same direction of rotation.
  • the winding shaft 6 To retract the awning 1, the winding shaft 6 must first be set in motion in order to lower the drop bar or the guide carriage 9, as a result of which the corresponding guide pin 44 now rests on the upper flank of the transverse guide groove 38, where it is aligned with that of the guide groove 37 facing side of the extension 43 comes into contact. Since this side is inclined in the direction of movement of the pin 44 toward the guide groove 37, the lever 45, with reference to the illustration in FIG. 2, is turned slightly further clockwise in order to finally reach the second highest point 54 of the transverse guide groove 38 . This second highest point 54 of the guide groove 38 is, based on the position of the pin 44, laterally next to or outside of the middle piece 39.
  • Locking gear 17 in one of three possible states.
  • the first state is when the guide pin 44 runs through the guide groove 36, which only occurs when the awning 1 is extended.
  • the guide pin 44 is located in the transverse groove 38, through which an upward movement of the corresponding guide carriage is blocked.
  • the third state of the ratchet mechanism 17 is finally when the guide pin 44 slides through the guide groove 37.
  • This state of the locking gear 17 is present when the awning 1 is retracted.
  • the switching of the ratchet mechanism 17 between the different states is effected, as is evident from the above, solely by the movement of the awning 1.
  • the arrangement of the guide grooves 36, 37, 38 is in the manner of a heart curve.
  • each guide rail 11, 12 has the shape of a square tube 57, which contains a continuous longitudinal slot 58 on a narrow side, to which a continuous rack 59 is attached on the inside of the square tube 57.
  • the guide carriage 9 has two flange plates 61 and 62 which run parallel and at a distance from one another and which are kept at a distance from one another by means of spacers 63.
  • the spacers 63 each consist of pairs of two pipe sections 64 and 65, with two immediately adjacent pairs of pipe sections 64, 65 between each a boom 66 is supported, which carries on its free end facing the square tube 57 on both sides two rotatably mounted rollers 67 and 68.
  • the total of four pairs of pipe pieces 64, 65 are arranged at the corners of the two rectangular flange plates 61 and 62 and are aligned with associated bores 69, 71, through which a total of four lag screws 72 pass, which are tightened on the other side by threaded nuts 73. In this way, a rigid frame is created which can run tilt-proof in the corresponding guide rail 57, the arms 66 projecting through the slot 58 into the interior of the square tube 57. For reasons of clarity, only the upper arm 66 is shown in the figure and the lower one with its rollers is omitted.
  • the flange plate 61 contains two bores 73 and 74 side by side, which are aligned with corresponding bores 75 and 76 in the other flange plate 62.
  • a round rod 77, 78 which is axially fixed by securing elements, not shown.
  • a cylindrical sleeve 79 is seated which is longitudinally displaceable and non-rotatable and which accordingly contains two continuous longitudinal bores 81 and 82 through which the round rods 77 and 78 pass.
  • the cylindrical bushing 79 forms part 32 of the locking mechanism 17 and can move back and forth between the two flange plates 41 and 42. In its outer circumference it contains guide grooves, the course of which results from the development 83 shown in FIG. 5, which is explained further below.
  • a tubular hub 84 is rotatably mounted, the axial length of which corresponds to the clear distance between the two flange plates 61 and 62.
  • a spur gear 85 which dips through the slot 58 into the interior of the square tube 57 and there meshes with the rack 59 attached to the inside of the square tube 57.
  • the scanning pin 44 which is provided on its rear side with an enlarged pressure plate 87 on which a compression spring 88 rests, is radially displaced around the guide pin 44 preload inside.
  • the rear abutment for the spring 88 forms a locking screw 89 screwed into a thread of the bore 86, which is not illustrated.
  • the sleeve 79 Since the sleeve 79 is part of the locking mechanism 17, the same reference numerals are used for the guide grooves contained in the sleeve 79 as for the guide grooves of the locking mechanism 17 according to FIG. 2, the assignment to the individual states of the locking mechanism 17 being retained. 5, the sleeve 79 contains in its cylindrical outer circumferential surface the guide groove 36 which extends in the circumferential direction and forms a closed annular groove. In addition to the other end face, the guide groove 37 is located at a distance from the guide groove 36, which also forms a closed annular groove, again with a rectangular cross-sectional profile.
  • the groove 38 that ends bluntly at an end corresponding to the recess 42, which is why this end is also designated 42.
  • two intermediate tracks or transfer grooves 91 and 92 extend from the guide groove 38, of which the transfer groove 91 connects the guide groove 38 to the guide groove 36 and the transfer groove 92 connects the guide groove 38 to the other guide groove 37. Both transfer grooves 91, 92 run obliquely to the surface line.
  • a third transfer groove 93 is provided, through which the guide groove 36 is connected directly to the guide groove 37.
  • the transfer groove 93 does not affect any other groove apart from the two guide grooves 91 and 92 mentioned.
  • the profile rises slightly at certain junction points of grooves, ie the bottom of the groove lies at an increasingly larger radius at these points before it suddenly returns to the old radius.
  • the location of these profile elevations as well as the angle of the grooves to each other results from the following functional description.
  • the starting position is assumed here that the awning fabric 7 is retracted, the scanning pin 44 being located at some point in the groove 37. This is the sleeve 79 moved in the direction of the flange plate 61. If the awning 1 is now extended, the two guide carriages 9 of the embodiment according to FIGS.
  • the tracer pin 44 is therefore guided out of the guide groove 37 at the edge 94, which corresponds to a displacement of the sleeve 79 in the direction of the flange plate 62.
  • the displacement will take place until the tracer pin 44 has passed the junction of the transition groove 93 into the guide groove 36, wherein it runs into the guide groove 36 from above with respect to the development 83. It has reached the other end position of the sleeve 79 next to the flange plate 62.
  • the tracer pin 44 will continuously run through the guide groove 36, ie with respect to the development 83, from top to bottom.
  • the stylus 44 runs unimpeded past the transition groove 43 opening at an acute angle.
  • the junction of the Transition groove 91 can pass through the stylus 44 unhindered, being deflected radially outwards by the groove profile which rises in the direction of the junction of the transition point 91 up to an edge 95, before, after passing the edge 95, the extension of the corresponding wall of the transition groove 91 runs, jumps back to the old radial position.
  • the winding shaft 6 is rotated in the opposite direction, as a result of which the spur gears 85, which are rotatably mounted on the sleeves 79 in the guide carriages 9, begin to rotate in the opposite direction, that is, in FIG. 3
  • the spur gear 85 shown rotates counterclockwise, which corresponds to a movement of the stylus 44 from bottom to top in the development 83 shown in FIG. 5. If the reversal of movement has taken place shortly before the stylus 44 has passed the edge 95, the stylus 44 will run back on the inclined ramp that falls from the edge 95 with respect to the development, and because there is no lateral force , easily pass through the transition groove 93 opening at the same level.
  • the scanning pin 44 will finally run against the edge 95 with its flank, since the height profile of the guide groove 36 undergoes an abrupt change from this side.
  • the stylus 44 will therefore move the sleeve 79 towards the flange plate 61 and enter the second guide groove 38, which ends at 42. Arrived in this "dead end", the scanning pin 44 blocks a further rotational movement of the spur gear 85 in the counterclockwise direction and thus another Lifting the corresponding guide carriage 9. Since both guide carriages 9 run synchronously, the other guide carriage 9 will also have entered the locked state.
  • the further rotation of the winding shaft 6 in the sense of retracting the awning 1 will only cause a further tensioning of the awning fabric 7 without the drop bar 8 being raised.
  • the winding shaft 6 To retract the awning 1, the winding shaft 6 must first be set in motion in order to extend the awning, as a result of which the spur gear 85 is rotated clockwise.
  • the stylus 44 now runs in the development 83 from top to bottom until it runs up on an edge 96 with its flank, which forces the stylus in the direction of the transition groove 92.
  • the edge 96 arises because the height profile of the transition groove 95 rises towards the guide groove 38 in the direction of movement of the scanning pin 44. Due to the lowering movement of the awning 1, the scanning pin 44 finally runs out of the guide groove 38 via the transition groove 92 into the guide groove 37.
  • the awning 1 can be retracted without hindrance, the scanning pin 44 running through the guide groove 37 in the counterclockwise direction, ie in the development 83 constantly from the bottom up. The initial state is finally reached again.
  • the awning 1 can therefore be locked at appropriate distances in the circumference of the spur gear 85 by initiating a reversal of movement in the sense of retracting the awning 1 after lowering to the desired height.
  • Fig. 6 an embodiment of the locking gear is shown, with the aid of which an additional locking slide is actuated in order to fix the guide carriage 9 in the position reached.
  • the associated guide rail is in turn the square tube 57, the side of which faces the guide carriage 9 is provided with the continuous longitudinal slot 58.
  • a continuous bar 101 is formed on the side next to the square tube 57 and carries the rack 59 on the side facing the guide carriage 9.
  • the guide carriage 9 contains two parallel and spaced apart flange plates 102 and 103, which are fastened to one another and kept at a distance in the same way as in the exemplary embodiment according to FIG. 3.
  • the guide rollers 67 and 68 are also in the same way the boom 66 is rotatably mounted and run, as before, within the square tube 57.

  • Another support roller 104 which runs on the back of the bar 101, is seated on a bracket 105 attached to the flange plate 102.
  • the guide grooves 36 and 37 are designed as concentric circular rings in the flange plate 103, which are concentric with an axis 106 about which a spur gear 107 rotates between the two flange plates 102, 103.
  • the same reference numerals are used for the designation of the guide grooves as in the previous exemplary embodiments and they also correspond to the previously explained operating states of the latching gear 17.
  • the guide groove 38 corresponding to the locked state with the closed end 42 lies between the concentric guide grooves 36 and 37 on one to the latter concentric circle, but extends only a little in the circumferential direction, the orientation of which follows from the following functional description.
  • the guide groove 38 is a “dead end”.
  • the guide grooves 36, 37 and 38 are in turn connected to each other by transition grooves 91, 92, 93, wherein at the confluence points, as seen in the direction of travel of the stylus 44, as before, inclined surfaces or jumps are formed, depending on the direction of movement of the stylus 44, in the to be distracted in one direction or another.
  • the edges appearing at the junction have the same as before Function of automatic switches.
  • the guide pin 44 is spring-loaded in a cylindrical housing 108 and is aligned axially parallel to the axis of rotation 106.
  • the housing 108 in turn is located in a radial groove 109 which is formed in a cylindrical projection 111 of the spur gear 107.
  • This cylindrical extension 111 faces the flange plate 103 and is connected in one piece to the spur gear 107.
  • Provided in the groove 109 are two mutually facing, radially extending guide strips 112 and 113 which engage in a corresponding circumferential groove 114 of the housing 108.
  • the housing 108 with the tracer pin 44 resiliently seated therein can therefore move radially in relation to the axis 106 in the radially extending groove 109, but is fixed in the direction parallel to the axis 106, that is to say axially with respect to the deflection direction of the tracer pin 44.
  • the scanning pin 44 is biased in the direction of the flange plate 103 by a compression spring attached in the interior of the housing 108 and can be pushed back into the housing 108 by a force acting on the flange plate 103.
  • an elongated hole 115 Aligned with the radially extending groove 109 is an elongated hole 115 which extends as close as possible to the toothing of the spur gear 107 and through which an actuating pin 116 rigidly attached to the cylindrical housing 108 protrudes beyond the side surface of the spur gear 107.
  • the actuating pin 116 cooperates with a cam 117, which is formed on a slide 118, which in turn is spaced apart on the flange plate 102 between two extending guide rails 119 and 120 is guided to be longitudinally displaceable.
  • the working direction of the slide 118 is perpendicular to the toothed rack 59.
  • An elongated hole 121 provided approximately in the middle of the slide 118 enables the passage of the axis (not shown) for the spur gear 107.
  • the cam 117 which is formed on that side of the spool 118 and which faces the spur gear 107 is adjacent, is delimited on its radially inner side by a circular arc surface 122 concentric to the axis 106, the radius of which is greater than the radius of the inner guide groove 36 plus the radius of the actuating pin 116.
  • This partially cylindrical surface 222 extends around a central angle of approximately 100 °.
  • Another part-cylindrical surface 123 which is also arranged concentrically to the axis 106, delimits the cam 117 radially on the outside, the radius of this part-cylindrical surface 123 being smaller than the radius of the outer guide groove 37 minus the radius of the actuating pin 16.

  • the two partially cylindrical surfaces 122, 123 are connected to one another by inclined surfaces 124 and 125, as illustrated. Their dimensioning results from the functional description below.
  • the spur gear 107 engaging the rack 59 rotates clockwise, the tracer pin 44 running through the guide groove 37 until it finally arrives at the junction of the transition groove 93, at which it is transferred to the inner guide groove 36.
  • the housing 108 is ver in the gear 107 radially inwards pushed.

  • the inclined surface 125 is set back correspondingly with respect to the transition groove 93.
  • the slide 118 is moved into its retracted position by a return spring, not shown, which acts between abutments 128 and 129, in which a toothing 131 attached to the front edge of the slide 118 is held out of engagement by the toothed rack 59.
  • the direction of movement of the awning 1 is changed, as before, which is why the spur gear 107 now begins to rotate in the counterclockwise direction and the scanning pin 44 is transferred from the transition groove 91 into the guide groove 38.
  • the housing 108 moves with the tracer pin 44 and the actuating pin 116 a corresponding distance in the spur gear 107 radially outward.
  • the actuating pin 116 is disengaged from the cam 117. If the direction of movement is reversed again in the sense of opening the awning 1, the tracer pin 44 now runs into the transition groove 38, which acts as a “dead end”, specifically with reference to FIG 6, counterclockwise around axis 106.
  • the awning 1 is first lowered a short distance, as a result of which the actuating pin 116 moves away from the inclined surface 124 so that the return spring can pull the slide 118 back into the starting position.
  • the stylus 44 finally runs through the transition groove 92 into the radially outer guide groove 37, through which the stylus 44 runs until the direction of movement is reversed.
  • the actuating pin 116 moves past the partially cylindrical surface 123 of the cam 117.
  • a kinematic reversal can also take place, insofar as the tracer pin 44 and the guide grooves 36, 37, 38 can swap places, for example by the lever 45 with the tracer pin 44 in the exemplary embodiment 2 on the guide carriage 9 and the lower section 25 containing the guide grooves 36, 37, 38 can be rigidly held on the guide tube 11.
  • FIGS. 7 to 11 show that it is also possible to advance the detent gear 17 in the winding shaft 6 see. It is then protected in the awning box and can be made relatively large without appearing visually.
  • a circular control disk 132 is seated coaxially and non-rotatably , 37, 38, 91, 92, 93 contains.
  • the guide grooves 36 and 37 form concentric circles to the bearing journal 130 or the axis of the winding shaft 6 and have a small lateral distance from one another.
  • the guide groove 38 which ends at 42 butt, is a circular arc section which also runs coaxially to the bearing journal 130, but has a smaller radius than the guide groove 36 which runs radially inward on the control disk 132 with respect to the guide groove 37.
  • the guide groove 38 is connected via the two transition grooves 91 and 92 on the one hand to the guide groove 37 and on the other hand to the guide groove 36, as shown.
  • the transition groove 92 cuts the guide groove 36 at the same height.
  • the guide groove 36 is directly connected to the guide groove 37 through the transition groove 93.
  • a locking acts with the control disk 132 slide 133 together, which extends over the entire length of the guide rail 57.
  • the locking slide 133 consists of a spring steel band and has an upper straight stretched section 134 and an underneath undulating section 135 which runs through the entire guide rail 57.
  • the upper section 134 of the approximately band-shaped locking slide is guided in a guide piece 136 in the direction tangential to the control disk 132 and can move back and forth in the direction parallel to the winding shaft 6 with play.
  • the guide piece 136 is attached to the rear of the guide rail 157 below the bearing pin 130.
  • the sliding block 138 At the uppermost end of the stretched section 134 there is a pin 137 which extends parallel to the axis of the winding shaft 6 and on which an approximately kidney-shaped sliding block 138 which can be seen in FIG. 11 is rotatably mounted. 7 to 9, the sliding block 138 has been omitted for the sake of clarity.
  • the sliding block 138 is dimensioned so that it can easily pass through the grooves of the control disk 132, but on the other hand, at the intersection where the transition groove 92 and the guide groove 36 intersect, maintains its direction so that it can be changed without changing the groove , runs over the interface.
  • the corrugated part 135 of the locking slide 133 interacts with a complementary corrugated contact piece 139, which is located inside the square guide rail 57 and on the inside of which is arranged opposite the longitudinal slot 58.
  • the contact piece 139 extends down the entire length of the guide rail 57.
  • Its wavy top 141 shows the same course as the wave-shaped locking slide 135, so that the locking slide 135 is advanced depending on the axial position with respect to the contact piece more or less in the direction of the carriage 58.
  • the locking slide 133 is laterally guided by two webs 142 and 143.
  • the two webs 142 and 143 are arranged in alignment with one another and also run in front of the elevations of the contact piece 139 over the entire length of the guide rail 57 below the guide piece 136.
  • the locking action of the locking slide 133 is achieved in that when the locking slide 133 is displaced correspondingly with respect to the contact piece 139, its equidistantly distributed undulating elevations 144 enter the clearance profile of the guide carriage reduced to a roller 9.
  • the roller 9 contains on its side facing the locking slide 133 a recess 145 into which the undulating elevation 144 can penetrate.
  • the elevations 144 may flatten elastically if an elevation 144 faces an edge of the guide roller 9 and cannot penetrate the recess 145 thereof.
  • the vertical awning described works as follows: It is initially assumed that the vertical awning is completely retracted and the sliding block 138 acting as a scanning element is in the Guide groove 37. If the winding shaft 6 is now set in revolutions for the purpose of extending the vertical awning, namely in a counterclockwise direction with respect to the illustration in FIG. 11, the sliding block 138 runs in the guide groove 37 in a clockwise direction. Since this guide groove 37 is located radially outermost on the control disk 132, the wave-shaped part 135 of the locking slide 133 assumes the position shown in FIG. 7 in relation to the contact piece 139, in which the elevations 144 are only slightly displaced downwards relative to the elevations 141 are. The locking slide 133 is therefore not significantly advanced on the slot 58, that is, it is still outside the clearance profile of the guide roller 9. The extension rod 8 can therefore run down unhindered when lowering further.
  • the sliding block 138 will have run so far through the guide groove 37 that it arrives at the point at which the transition groove 93 branches off from the guide groove 37. Since inclined surfaces and edges are provided there, as described in the previous exemplary embodiments, the sliding block 138 is deflected out of the guide groove 37 into the transition groove 93. It is now after a further movement of the winding shaft 6 in the guide groove 36, which has a smaller distance from the axis of the winding shaft 6. As a result, the locking slide 133, which is laterally guided in the direction tangential to the control disk 132, is raised to a certain extent in accordance with the radius difference between the two guide grooves 36 and 37.
  • the sliding block 138 begins, with reference to FIG. 11, now moving counterclockwise through the guide groove 36.
  • the change in direction of rotation allows the sliding block 138 to run into the transition groove 91 from the guide groove 36, since the sliding block 138 is deflected out of the guide groove 36 by inclined surfaces, as explained in detail in the previous exemplary embodiments.
  • the locking slide 133 is raised further, so that its elevations 144 shift more than the elevations 141.
  • the locking slide 133 is thereby driven with its corrugated part 135 in the direction of the guide roller 9 and can engage with one of its undulating elevations 144 in the recess 145.
  • the guide roller 9 is thereby fixed in the guide rail 57 in both directions, as shown in FIG. 8.
  • the winding shaft 6 is first stretched a little in the direction of the extension Movement set, whereby the sliding block 138 runs from the guide groove 38 into the transition groove 92. This downward movement continues until the sliding block 138 has arrived in the guide groove 37. During this movement, the locking slide 133 is gradually lowered and can disappear again between the elevations 141 of the contact piece 139, as a result of which the guide roller 9 can move freely in the guide rail 57.
  • the winding shaft 6 can now be moved in the sense of retracting the awning 1, the sliding block 138 being able to easily pass the junction of the transition groove 92 into the guide groove 37.
  • the ramps and sliding surfaces described in the previous exemplary embodiments prevent the sliding block 138 from running back into the transition groove 92, which extends at an acute angle. The initial situation according to FIG. 7 is thus achieved.
  • the drop bar 8 is locked not only on one side but on both sides in order to prevent skewing when the wind reaches under the extended awning fabric.
  • a locking slide is therefore preferably also provided in the other guide rail, designated 11 and 12 in FIG. 1.
  • the actuation of this other locking slide can either take place with a further control disk, which is designed as a mirror image of the control disk 132 and is located at the other end of the winding shaft 6, or it can be displaced by means of a gear shaft, as is shown schematically in FIG. 11.
  • a further control disk which is designed as a mirror image of the control disk 132 and is located at the other end of the winding shaft 6, or it can be displaced by means of a gear shaft, as is shown schematically in FIG. 11.
  • a gear toothing 147 is provided on an edge of the locking slide 133, into which a spur gear 148 engages, which is rotatably mounted below the winding shaft 6 parallel to the latter.
  • a shaft coupled to the spur gear 148 which is not visible in FIG. 11 because of the illustration, leads to the guide rail which is provided at the other end of the winding shaft 6.
