Definitions

  • the invention relates to an awning with the features of the preamble of claim 1.
  • a generic Markisolette which contains below the winding shaft two vertical guide rails running parallel and at a distance from each other, which are to be attached on both sides next to the window of a building.
  • Two guide slides run on the two guide rails, which are connected to each other at their upper end via a rotatably mounted deflection roller for the awning fabric.
  • Each of the guide slides carries on his lower end a hinge joint for a drop arm, which is biased towards the unfolded position by means of a spiral spring.
  • the free ends of the two extension arms are also connected to each other by the extension rod to which the free end of the awning cover is attached.
  • the aim is to ensure that when the awning cover is extended following the maximum possible downward stroke of the guide slides, the extension arms begin to swing out so that the awning cover, which runs under the deflection roller, is tilted outwards away from the window.
  • the hinge joints for the drop arms consist of a bearing pin fastened to the guide slide, on which the respective drop arm is pivotably seated with a corresponding bore.
  • the coil spring is arranged next to it and does not take on any radial forces, because these are only transmitted from the hole in the extension arm to the bearing journal. This construction is very widespread in practice, but takes up considerable space in the lateral direction because the spring sits next to the hinge joint. The arrangement looks too bulky when it comes to markisolettes on small room windows.
  • a particularly good lateral guidance can be achieved if the spiral spring is designed as a band spiral spring, as a result of which larger forces can be transmitted in the lateral direction, that is to say parallel to the drop rod.
  • the mounting and mounting of the coil spring does not require any clamping devices if the pin on which the coil spring is seated is provided with an opening for receiving the corresponding end.
  • this opening is a slot open to one end of the bearing journal, which ensures that the coil spring is easily attached.
  • connection of the spiral spring to the extension arm is also very simple if the outer end of the spiral spring is angled so as to protrude radially outwards and this end is inserted into a corresponding opening of the extension arm.
  • a simple self-locking shaft locking ring which is pushed onto the bearing journal, is sufficient.
  • This can optionally be connected in one piece with a cap in order to close off the free end of the bearing journal.
  • the awning according to the invention can be designed both as a drop arm awning and as an awning isolate.
  • the swivel bearing of each extension arm is stationary next to the window to be shaded, while in the case of the marquette, two guide rails are provided next to the window on which the guide slides run, which in turn carry the swivel bearings for the extension arms.
  • the filigree impression of the new swivel bearing is retained if the stop provided at the lower end of the movement stroke of the guide carriage is provided with a wire eyelet which interacts with the bracket provided on the extension arm.
  • this bracket has the task of ensuring that when the awning cover is retracted, the extension arms are first folded against the action of the spiral springs on the guide carriage before the guide carriage moves upwards when the awning cover is retracted further.
  • This bracket does not have to take on excessive forces and can therefore be designed as a wire bracket, in any case it has the shape of an arc that is concentric with the center of the coil spring.
  • an awning isolate 1 is illustrated, which is attached in front of a window 2 of a building, not shown, and in a box 3 open at the bottom contains a winding shaft (not visible), onto which an awning cloth 4 can be wound, with its rear edge on the winding shaft is attached.
  • a winding shaft not visible
  • the two guide rails 5 and 6 are held at their lower end adjacent to the lower edge of the window 2 by wall brackets 7, while the upper end is connected to the box 3.
  • the two guide rails 5 and 6 are used for the displaceable mounting of two mutually identical but mutually mirror-image guide carriages 8, at the upper end of which a deflection roller 9 is rotatably mounted, which extends between the two guide carriages 8.
  • the lower end of each of the two guide carriages 8 carries a pivot bearing 11, via which a drop arm 12 is pivotally connected to the associated guide carriage 8.
  • the pivot axes of the two pivot bearings 11 lie at the same height and are aligned with one another, i.e. they lie on a common straight line which is parallel to the axis of the winding shaft or the deflection roller 9.
  • a drop bar 13 is connected to which the front edge of the awning fabric 4 is anchored.
  • the Markisolette 1 in Fig. 1 is shown in a partially extended position, in which the two guide carriages 8 their lowest position on the Have reached guide rails 5, 6 and the two parallel extending arms 12 are pivoted out away from the window 2.
  • the awning cloth 4 therefore runs between the box 3 and the deflecting roller 9 approximately vertically and starting from the deflecting roller 9 up to the drop bar 13 obliquely downwards from the window 2.
  • the pivot bearing 11 of the guide carriage 8, which runs on the guide rail 5, is shown in FIGS. 2 and 3 in detail.
  • the pivot bearing 11 of the other guide carriage 8, which is guided in a longitudinally displaceable manner on the guide rail 6, is mirror-symmetrical, so that the description given below also applies to the other pivot bearing.
  • the guide carriage 8 has at its lower end a sleeve 16 provided with two mutually parallel through bores 14 and 15, which is tapered in the form of a web between the two bores 14 and 15.
  • the guide rail 5 runs through the bore 14 with little play, so that the sleeve 16 can be easily pushed back and forth on the guide rail 5.
  • a cylindrical strut 17 is clamped in the bore 15 and leads to an upper guide sleeve 18, on which the deflection roller 9 is rotatably mounted.
  • the guide sleeve 18 can also be easily pushed back and forth on the guide rail 5 with little play.
  • the distance between the sleeves 16 and 18 is slightly larger than the extension arms 12 are long.
  • the guide sleeve 16 carries a cylindrical bearing pin 19, the longitudinal axis of which is perpendicular to a plane which contains the longitudinal axes of the two bores 14 and 15.
  • the bearing pin 19 protrudes on one side and goes on the sleeve 16 adjacent to it End in a flat annular shoulder 21. It serves as a seat for a coil spring 22, the inner end 23 of which is bent radially inward and the outer end 24 projecting radially outward. With the inner section 23, the coil spring 22 engages in a longitudinal slot 25 of the bearing pin 19.
  • the longitudinal slot 25 is open to the free end of the bearing pin 19 and points in the direction of the bore 15.
  • the width of the slot 25 corresponds to the material thickness of the coil spring 22 , which has about three to four courses.
  • a washer 26 is arranged between the annular shoulder 21 and the spiral spring 22 and there is also a further washer 27 on the side of the spiral spring 22 remote from the sleeve 16, which has the same dimensions as the washer 26.
  • the axial securing of the washers 26 and 27 as well as the spiral spring 22 on the bearing journal 19 is carried out by a securing element 28, which is designed in the manner of a self-locking locking washer, which integrally formed on a dome-shaped cap 29.
  • the extension arm 12 is placed on the section 24 of the spiral spring 22 with a corresponding slot.
  • the slot is not shown in the figures; instead, section 24 is illustrated in dashed lines in FIG. 2.
  • the slot is pressed together after the section 24 has been inserted in order to establish a frictional connection between the section 24 and the extension arm 12.
  • a wire bracket 32 is seated in two mutually parallel bores, which has two mutually parallel legs 33 and 34, which are integrally connected at 35 at their end remote from the extension arm 12.
  • the wire bracket 32 has the shape of a circular arc which, when the pivot bearing 11 is mounted, as can be seen in FIG. 2, is concentric with the axis of the bearing pin 19.
  • the deepest point that the guide carriage 8 can reach on the respective guide rail 5, 6 is defined by an adjusting ring 36, which is clamped by means of a clamping screw 37 at the corresponding point on the guide rail 5 or 6.
  • the guide slide 8 with the coil spring 22 strikes a wire eyelet 38 of the adjusting ring 36, as a result of which further downward movement is limited.
  • the wire eyelet 38 stands radially away from the guide rail 5 or 6 and its distance from the bearing pin 39 is dimensioned such that when the spiral spring 22 stands on the eyelet 38, it is the same size as the radius of curvature of the bracket 32.
  • the eyelet 38 lies parallel to the trunnion.
  • the awning 1 described so far works in the following way: If it is initially assumed that the awning 1 is completely retracted, the two extension arms 12 are pivoted vertically upwards, the extension rod 13 running just below the deflection roller 9. In addition, the sleeves 18 of the two guide carriages 8 rest on the upper fastening of the two guide rails 5, 6.
  • the two guide carriages 8 first run on the guide rails 5 and 6 downwards until the sleeve 16 located at the bottom of the guide carriage 8 stands on the respective adjusting ring 36.
  • the two adjusting rings 36 are mounted on the two guide rails 5 and 6 at the same height.
  • the extension arms 12 are pivoted outwards away from the wall due to the resilience of the coil spring 22.
  • the wire bracket 32 enters the wire eyelet 38.
  • the awning fabric 4 which occurs under the deflection roller 9, is held taut by the effect of the weight of the extension rod, 13 of the two extension arms 12 and the torque generated by the two coil springs 22, so that the in FIG. 1 recognizable position comes about.
  • the extension arms 12 pivot more or less far down.
  • the awning cloth 4 is again wound onto the winding shaft, whereby a force is generated which tends to pull the guide carriages 8 on the guide rails 5 and 6 upwards.
  • the guide carriages 8 are prevented from this upward movement by the two brackets 32 which are inserted in the wire eyelets 38.
  • the extension arms 12 are therefore first pivoted upward against the force of gravity and against the torque exerted by the spiral springs 22. Only when the drop arms 12 are almost completely pivoted upwards come on both sides of the wire bracket 32 free from the wire eyelets 38 so that the awning cloth 4 can lift the guide carriage 8.
  • the extension arms 12 in the awning 1 are connected exclusively to the associated guide carriages 8 via the spiral spring 22.
  • the spiral spring 22 therefore also takes over the transmission of the transverse or tensile forces to or from the respective extension arm 12.
  • a direct connection between the bearing pin 19 and the extension arm 12 does not exist, so that when the extension arm 12 is pivoted no sliding Friction between the drop arms 12 and the bearing pin 19 occurs.
  • the washers 26 and 27 are only used to improve the lateral guidance of the coil springs 22 and are intended to prevent foreign bodies from entering between the layers of the coil springs 22.
