Definitions

  • the invention relates to a spring shaft with the features of the introductory Part of claim 1.
  • Known spring shafts such as those used for roller blinds (roller blinds) have a locking mechanism, which allows the roller blind in any height by a counter pressure.
  • the Back pressure releases the lock, which is arranged inside the shaft bearing is out.
  • Such locks are usually designed so that a Blocking part, e.g. a ball, under the action of gravity a recess falls and blocks the rotation of the shaft.
  • a disadvantage of the known spring shafts is that when removing the spring shaft increased attention and adherence to the right ones Location is required to ensure that the lock is activated and remains. If this is not observed, the Danger that the spring suddenly when removing the spring shaft relaxed and the spring or other parts of the spring shaft damaged become. There is also a risk that the person holding the spring shaft expands, gets hurt. Even when installing the known Spring shafts must be paid attention to a certain position, what for Spring shafts are often attached to brands that fit into one another must be brought into alignment to ensure that the Lock is activated and remains activated.
  • the invention is based, in particular for the task Use of sun protection curtains or insect screens to provide certain spring shafts, which are so designed is that with the spring shaft removed, even if on a certain Orientation and rotational position of the spring shaft is not taken into account, a complete relaxation of the spring is excluded.
  • the relaxation of the spring when removing prevents a locking device under the effect of the axial tensile force of the spring of the spring shaft activated is, so that after a short rotation, for example about one Quarter turn or half turn another twist and thus preventing the spring of the spring shaft from completely relaxing is.
  • This ensures that the is in a stationary mounted bearing taken part of the spring shaft when removing the spring shaft does not turn uncontrollably and the person who the Spring shaft installed or removed, can injure.
  • Another advantage of the locking system according to the invention, which is built into the spring shaft, is that it works in any position, so that the spring shaft according to the invention can be used not only for vertical, but also for horizontal or inclined, rollable flat structures.
  • Another advantage over known spring shafts can be that the diameter of the shaft on which the flat structure is wound can be chosen to be smaller, which, for example, requires less space for installation and / or allows a reduction in the size of the roller blind box.
  • the invention is particularly for sun protection curtains and insect screens thought because with this any intermediate positions are usually not necessary as sun protection curtains or insect screens either fully open or fully are closed.
  • the spring shaft according to the invention has a fabric shaft 1, e.g. out Aluminum, which is designed as a tube.
  • a fabric shaft 1 e.g. out Aluminum
  • One end of the spring shaft is via a bearing part 2 inserted into the fabric shaft 1 and one Bearing pin 3 in a bearing 4, for example with the help of Screws 5 on a roller blind box or if such is not provided is on a window or door frame or on the edge of the Opening into any component (which can also be a vehicle can) is attached, rotatably mounted (Fig. 1).
  • the other end of the spring shaft (Fig. 2), namely the end of the spring shaft, in which a spring 6 is arranged is via a bearing 7, the just like the bearing 4 attached to a component with the help of screws 5 can be rotatably supported.
  • the clamping part 8 has a through opening 11 (FIG. 5) in which axially parallel ribs 10 are provided.
  • a spring guide rod 12 (Fig. 7) with her serrated end 13 inserted so that they are opposite the clamping part 8th is not rotatable.
  • a cylindrical extension 14 of the clamping part 8 is used Pushed spring receiving part 15, which is rotatable relative to the clamping part 8 is.
  • the spring receiving part 15 carries one with an external thread provided section 16 on which the spring 6 (for example a steel coil spring), e.g. can be screwed.
  • the spring receiving part 15 carries ribs extending in the axial direction 17, which engage in the fabric shaft 1 and the fabric shaft 1 rotatably connect with the spring receiving part 15.
  • the spring guide rod 12 is displaceable in the axial direction the spring receiving part 15 inserted, the spring receiving part 15 is also rotatable relative to the spring guide rod 12.
  • the spring guide rod 12 is on her not included in the clamping part 8 End 18 slotted so that the spring 6 with the spring guide rod 12 coupled over its end there for rotation can be by placing a bent end of the spring 6 in a slot 19 is inserted at the end of 18.
  • a star 20 Fig. 8 inserted opposite the spring guide rod 12 is rotatable and the fork-shaped end 18 of the spring guide rod 12 centered in the tissue shaft 1.
  • the spring receiving part 15 has in the area of its with the external thread provided, the spring 6 receiving section 16 at least one, preferably two or more, asymmetrical cutouts or recesses with inclined surfaces 25, as is particularly the case in FIGS 3 and 4 and 6 is shown.
  • the cutouts with the inclined surfaces 25 can extend to the outer surface the section 16 of the spring receiving part 15 range, as shown in 3, 4 and 6 is shown, but it is also possible that the Cutouts with the inclined surfaces 25 only on the inner surface (In the area of the through hole of the spring receiving part 15) arranged are so that the threaded portion 16 of the Spring receiving part 15 is not interrupted.
  • Such an embodiment of the spring receiving part 15, in which the cutouts with the Sloping surfaces 25 only within the through hole of the spring receiving part 15 are arranged, is in Fig. 6a in axial section shown.
  • the spring guide rod 12 carries at a distance from it with longitudinal ribs provided, toothed and included in the clamping part 8 End 13 an annular projection 27, the formations with inclined surfaces 26 has.
  • These formations with inclined surfaces 26 can as a "ratchet locking part” with those acting as a “ratchet counterpart” Cutouts interact with inclined surfaces 25 of the spring receiving part 15, around the spring receiving part 15 with respect to the spring guide rod 12 against rotation to relax the spring 6 to couple.
  • the locking position shown in Fig. 4 of the invention Spring shaft is in section in Fig. 10 for the spring receiving part 15 shown in FIG. 6a. It can be seen from FIGS. 4 and 10 that by the axial train of the spring 6, the formations with the Inclined surfaces 26 on the spring guide rod 12 in the cutouts of the spring receiving part 15 engage with the inclined surfaces 25 and the clamping part 8 is pushed out of the spring receiving part 15.
  • a spring shaft with a fabric shaft 1 has a spring 6, which is provided between a spring guide rod 12 and a spring guide part 15.
  • Two projections with inclined surfaces 26 are provided on the spring guide rod 12 and two cutouts with inclined surfaces 25 are provided on the spring guide part 15.
