  • the present invention is therefore an object of the invention to provide a device of the type mentioned, which takes up little space with simple installation.
  • the holding part has a top of the spring element associated retaining plate from which protrudes the hook assembly, wherein the spring element has an opening arrangement for the passage of the hook assembly, which is smaller in area than the retaining plate.
  • Another advantage is that there are virtually no exposed sharp edges. In contrast, relatively many edges are formed in the known device, which can injure themselves during assembly or the roller shutter can be damaged.
  • the device according to the invention is also simple in construction and inexpensive to manufacture.
  • the holding part consists practically only of the holding plate and the hook assembly.
  • Such Holding part can be made as a sheet metal part with integrally formed by punching and bending to the holding plate hook assembly.
  • the holding part Before the spring element is attached during assembly to the winding shaft, the holding part is inserted with its hook assembly through the opening arrangement of the spring element, if it is not a solidly connected unit from the front, after which the hook assembly with corresponding obliquely held spring element by the Passage opening of the winding shaft and pivots the spring element with the holding part in the use position, so that the hook assembly engages behind the wall of the winding shaft and thus holds the spring element securely on the winding shaft. This results in a tangential orientation of the spring element with respect to the winding shaft.
  • the device according to the invention is not only suitable for blinds but also for other roller blinds.
  • a roller shutter consists of hinged with their long sides together, usually made of plastic, slat-like shutter bars, of which in Fig. 1, the top shutter roller bar 1 is shown.
  • the roller shutter is one about their axis line 2 rotatable in the shutter box or the like.
  • winding shaft 3 assigned to which the roller shutter shell wound up when pulling up or from which the roller shutter armor unwinds when it is discharged when the respective window or door in question.
  • the required rotation of the winding shaft 3 can be done by means of a manually operated drive or housed in the interior of the winding shaft 3 drive motor.
  • the winding shaft 3 is designed for this purpose as a hollow shaft.
  • roller shutter rod 1 To connect the uppermost roller shutter rod 1 with the winding shaft 3 serve band-shaped, made of leaf spring material spring elements 4, so-called safety springs, which are arranged in the longitudinal direction of the winding shaft 3 with distance to each other.
  • the spring elements 4 consist essentially of a elastic sheet metal strip which is connected at one end to the roller shutter rod 1 and the other end to the winding shaft 3.
  • the present invention is concerned with the connection of the spring element 4 with the winding shaft 3. This assembly takes place when already in the shutter box or the like. mounted winding shaft 3.
  • the shaft-side end 7 is assigned a connection to the winding shaft 3 producing holding part 8, which has a hook assembly 9 which is arranged in the composite with the spring element 4 state of the holding part 8 on the underside 11 of the spring element 4 and protrudes in front of them.
  • the hook assembly 9 is associated with a passage opening 10 in the wall of the winding shaft 3, wherein the dimensions are made so that the hook assembly 9 in a mounting pivot position (Fig. 6) of the holding part 8 through the passage opening 10 fits, after which the hook assembly 9 through Pivoting the spring element 4 - the holding part 8 makes this pivotal movement with - in a use position (Fig. 1,7 and 8) passes, in which it engages behind the wall of the winding shaft 3, as shown in particular in Fig. 8 can be seen.
  • the dismantling is easy if the spring element 4, for example, to perform repairs on the roller shutter from the winding shaft 3 must be removed.
  • the spring element 4 is pivoted in the opposite direction, so that the hook assembly 9 enters the assembly pivot position and can be pulled out of the passage opening 10.
  • the spring element 4 is attached to the winding shaft 3, it runs tangentially and at right angles to the longitudinal direction of the Winding shaft 3 away from this.
  • the hook assembly 9, the wall of the winding shaft 3 engage behind substantially free of play, so that the spring element 4 can not spread away from the winding shaft 3.
  • the holding part 8 has a holding plate 13 assigned to the upper side 12 of the spring element 4, from which the hook arrangement 9 protrudes.
  • the holding plate 13 has a planar shape and lies flat against the top 12 of the spring element 4.
  • the spring element 4 contains an opening arrangement 14 for the passage of the hook arrangement 9, wherein the opening arrangement 14 is smaller in area than the holding plate 13.
  • the holding plate 13 may be formed relatively thin-walled, so that it represents an insignificant thickening of the winding shaft. Also, the interior of the winding shaft 3 is practically not concentrated, since the hook assembly 9 may be correspondingly thin-walled.
  • the holding part 8 is a sheet metal part integrally formed by punching and bending the retaining plate 8 hook assembly 9.
  • the hook assembly 9 is formed by a punching tongue assembly.
  • the hook assembly 9 includes in the embodiment of two pointing in opposite directions single hooks 15,16.
  • the two individual hooks 15, 16 each have an L-shaped configuration, wherein the one L-leg 17 protrudes from the holding plate 13 and the other L-leg 18 at a distance from the holding plate 13 parallel to this runs (the reference numerals 17,18 for the two L-legs were entered for clarity only in Fig. 4 at the single hook 15).
  • the distance between the holding plate 13 and the L-leg 18 corresponds to the sum of the material thicknesses of the spring element 4 and the wall of the winding shaft 3 and is a little larger than this.
  • the edge 19 of the passage opening 10 of the wall of the winding shaft 3 limits the displacement play of the hook assembly 9 and thus of the holding part 8 and the spring element 4 parallel to the plane of the spring element in the assembled state.
  • the two individual hooks 15, 16 are spaced apart from one another by the retaining plate 13.
  • the holding plate 13 forms between the two each formed by punching and bending one of the individual hook punch holes 20,21 a web 22.
  • the opening arrangement 14 of the spring element 4 of two each one of the individual hooks 15 and 16 associated with individual openings 23,24 formed, through which the individual hooks are inserted. Between the two individual openings 23,24, the spring element 4 forms a web 25 on which the web 22 of the holding part 8 rests.
  • the two individual hooks 15,16 extend on both sides of the spring element web 25 with its L-leg 17 close to the web 25 over, so that its two side edges 26,27 form stops for the L-leg 17, the holding member 8 against displacement relative to the spring element Secure 4 in its transverse direction.
  • the measured in the longitudinal direction of the spring element 4 dimension of the individual openings 23, 24 corresponds substantially to the same directional dimension of the L-leg 17 of the individual hooks 15,16, so that the holding part 8 is fixed in this direction.
  • the opening arrangement 14 of the spring element 4 could also be formed by only one opening, which is correspondingly larger, so that both individual hooks can be pushed through. In this case, however, the holding part 8 and the spring element 4 could be displaced in the transverse direction relative to each other.
  • the holding part 8 and the spring element 4 are also connected to each other substantially rotationally.
  • the hook arrangement 9 and the opening arrangement 14 are designed and arranged relative to one another in such a way that a non-rotatable hold of the holding part 8 on the spring element 4 results. This is achieved in the embodiment by the spring element web 25 and projecting from the holding plate 13 L-leg 17 of the two single hooks 15, 16.
  • the holding part 8 is in the illustrated embodiment, a loose part of the spring element 4, which is inserted only in the case of application during assembly with its hook assembly 9 through the opening arrangement 14 of the spring element 4.
