Definitions

  • the present invention relates to a mounting device for a spring roller blind with a winding core axis, with a bearing journal connected to the winding core axis in a rotationally fixed manner, which projects axially outward and is held non-rotatably in a bearing opening of a 1-element element, the bearing journal with the side walls of the bearing opening in an anti-rotation manner Has engaging stop surfaces.
  • roller blinds Such mounting devices for spring blinds are known.
  • the installation of the roller blind is possible in different ways depending on the application. For some applications a self-locking of the roller blind is desired, in other areas of application, especially for roof windows, a constant tension of the fabric is necessary, so that a self-locking of the roller blind, through which the tension would be lost, must not occur.
  • the mechanism of self-locking is effected in the roller blind rod in that the winding core axis has a notch into which an engaging element can enter. When the notch is oriented upwards, the engaging element falls into this notch by gravity, the self-locking takes effect.
  • the object of the invention is to reliably prevent incorrect installation of the spring blinds.
  • the bearing pin has an asymmetrical shape which can be inserted into an undercut bearing slot and which engages at least one undercut side edge of the bearing slot in the installed position.
  • the mounting direction is not just an optical one Display fixed, rather the journal can only be inserted in the undercut bearing slot due to the asymmetrical shape in a predetermined direction.
  • the notch of the winding core axis is aligned in the desired manner. So if it is necessary for the specified application that the roller blind tension is constantly maintained, for example in skylights, the notch of the winding core axis and the bearing journal are geometrically aligned so that the notch of the winding core axis points downward when the bearing journal is inserted. A self-locking is then no longer possible.
  • the bearing pin has a mounting lug engaging behind the undercut points.
  • the bearing journal is widened at its end inserted into the bearing slot, approximately in the form of a half dovetail. In this way, unintentional pulling out of the bearing journal from the bearing slot in the axial direction is impossible without Damage the bearing slot or bearing journal.
  • a preferred embodiment provides that the bearing journal is inclined to the winding core axis and has two walls lying parallel to one another and lying against the side walls of the bearing slot.
  • This form of the journal is particularly simple in production, since the journal can be rectangular in cross-section, with walls running parallel to one another.
  • This bearing journal is attached to the winding core axis at an angle, preferably approximately 30 to 45 degrees, to the winding core axis. Since the bearing surfaces of the bearing journal in the bearing slot move away from the axis of rotation of the roller blind in this way and thus the support points are at a greater distance from the roller blind axis, the supporting force is simultaneously reduced due to the longer Ilebelweg, so that the material stress on both the bearing journal and the Side walls of the bearing slot is reduced.
  • the undercut bearing slot advantageously has a curved or angled shape which does not prevent the insertion of the bearing pin.
  • the course of the bearing slot is expediently such that it first runs over a partial area in the horizontal direction and then leads vertically downward. This results in simple insertion of the bearing journal with secure storage.
  • a support element 1 and a spring roller blind shaft 2 are shown.
  • the support element 1 consists of a plate-shaped part, the front edge 11 of which extends at right angles to the lower edge 12.
  • the front edge 11 and the rear edge 13 run parallel to each other ver.
  • the upper edge 14 and the lower edge 12 form an angle in their extension, so that the front edge 11 is somewhat longer than the rear edge 13.
  • the two plate sides 20 and 21 likewise run at an acute angle to one another, so that the plate is thicker in the region of the front edge than in the region of the rear edge 13.
  • the front edge 11 projects somewhat in the region of the upper edge, this projection is in 1 with the reference numeral 15.
  • the front edge 11 also protrudes somewhat beyond the side 21 of the plate.
  • This special shape is provided so that the plate in the upper left corner of a skylight frame is firmly against the upper frame bar and the side frame bar, the front edge 11 limiting the displacement of the support element 1 to the rear. Screw holes 19 are provided for fastening the plate-like support element 1 in the window frame.
  • a bearing slot 1 6 is provided, which starts at the front edge 11, extending over a first portion parallel to the lower edge 12, then a rounding 17 and has parallel on the last portion 18 to the edge 11 downwards.
  • the bearing slot 16 leads through the entire support element from one side 20 to the other side 21 with the exception of the area at the front edge. A jetty has been left here.
  • the shape of the bearing slot selected in FIG. 1 is such that the two side walls run at an angle to one another, so that the bearing slot 16 has approximately the shape of a dovetail groove.
  • the profile of the bearing slot 16 is not symmetrical, in the present case a recess 22, i.e. the undercut area, faces upwards, so that the upper boundary surface of the bearing slot extends obliquely to the edge surface 12, while the lower boundary surface of the slot runs parallel to the edge surface 12.
  • a bearing journal 31, which is fastened to the winding core axis of the roller blind rod 30, corresponds to this special shape.
  • This journal 31 has a projection 32 which can be inserted into the recess 22.
  • Bearing journal 31 and bearing slot 16 thus act together like a lock and key. If the bearing pin 31, which is shown in FIG. 1, were rotated by 180 degrees so that the nose 32 points downward, the pin could no longer be inserted into the slot. It is thus ensured that the bearing journal can only be inserted into the bearing slot 16 of the support element 1 in a single, specific, defined manner. This means that the position of all components and mechanisms connected to the winding core axis is fixed; accidental misalignment is not possible. In particular, if the bearing journal 31 lies in the section 18 of the guide slot, the notch in the interior of the roller blind rod 2 is oriented in the desired direction.
  • Fig. 2 shows a further embodiment, the principle of which is clear in the front view.
  • the support element 1 which can be similar in structure to the support element according to FIG. 1, but can also have any other suitable dimensions, has the bearing slot 16 for introduction.
  • the two side walls of the bearing slot 16 run parallel to one another, one of the two walls, in present example, the upper wall 23 is undercut.
  • the slot 16 is guided to the rear in a first horizontal and then vertical section.
  • the pin 31 is formed, which has two parallel walls 33 and 34, the side wall 33 of the pin 31 abutting the undercut side wall 23 of the bearing slot 16, while the other side wall 34 is correspondingly on the opposite side.
