Definitions

  • the invention relates to a differential gear based Endlagenabschaltvorides a powered by an electric drive blind according to the preamble of claim 1.
  • Such Endlagenabschaltvoriquesen are, for example, by EP-A1-0 844 633 and EP-B1-0 665 361 known.
  • the notches in the indexing disks are usually considered as simple V-shaped cuts formed.
  • the caster is the angle that the output shaft of the Electric drive and thus the drive pinion of Endlagenabschaltvortechnisch swept after switching off in the de-energized state. He is dependent on Ratio between speed of the drive shaft (motor shaft) and the speed of the indexing disc, the response and effectiveness of Brake and the inertia of the rotating parts. In addition, can itself due to wear the braking effect deteriorate, causing the caster increased. A safe function is only by an independent of the caster Endpositionabschaltvortechnisch possible, but the acquaintance with relative high constructive effort is connected.
  • DE-C2-30 11 260 is a switching device for the electrical Drive of roller shutters known, the two at different speeds driven cam wheels with profile notches has, in the two Druckarmspitzen (Tastmaschine) for engaging a switch can intervene.
  • the backward Wall of each profile notch is chamfered to the rear and laterally outward and merges into a cam portion whose radial height is about the tread groove depth point equivalent.
  • the switching arm tips and the beveled Walls of the profile notches glide together as the cam wheels continue to rotate and move laterally elastically against each other.
  • the object of the invention is therefore a simple Endlagenabschaltvorraum to create the mentioned in the preamble of claim 1, at the safe shutdown of the electric drive after reaching the end position remains guaranteed.
  • Another advantage of the invention is that the open arc segment the notches arranged on the circumference of the indexing disc by an asymmetrical Training can be kept minimal. This allows the teeth ratio the differential gear as close as possible 1, whereby a large adjustment range of Endlagenabschaltvoriques arises.
  • the Relative movement of the switching discs to each other and the length of the open arc segments must be coordinated so that the open arc segments the two switching discs one revolution before the actual end position are offset from each other so that the Wegarmspitze can not come.
  • the smaller the open arc segment the lower the relative movement per revolution of the switching discs to each other. The lower the Relative movement is, the closer that is the teeth ratio of the Differential gear at 1.
  • the shift gate as the adjacent switching disc open groove to create a arcuate, radially outward groove wall formed.
  • a further embodiment of the invention is made such that the switching arm tip two laterally outwardly projecting webs for inclusion in the notches and scenes having the switching discs and that between the webs and the Shift arm in each case a groove for receiving the associated groove wall of the indexing disk is provided.
  • the guidance of the switching arm upon incidence into the shift gate can e.g. in two different types take place:
  • the preloaded shift arm tip slides when it enters the shift gate first on the circumference of the indexing disc, then down along the notch slope to the groove bottom of the open groove.
  • the other variant provides that the preloaded Wennarmspitze when Slipping into the shift gate only on the circumference of the shift window, but then down the notch slope, but then in the groove of the Shift arm guided along the groove wall of the shift gate. The bottom of the groove open groove is then no longer necessary.
  • the height of the groove wall is around at least half the width of the web of the switching arm is lower than that Width of the indexing disk on the circumference of the indexing disk. This will be the Shift arm when falling into the shift gate axially in the between the two Slots resulting slot out.
  • a hollow drive pinion 3 is mounted in a tubular housing 1 on a Base plate 2 of the housing 1 centrally a hollow drive pinion 3 is mounted.
  • the cavity 4 of the drive pinion 3 serves to receive the output shaft of the not shown electric motor of a blind, which also from this output shaft is driven.
  • the arranged on the circumference of the drive pinion 3 Teeth interfere with teeth on the circumference of four on the base plate 2 mounted gears are arranged.
  • left and right are only the To see gears 5, 7.
  • Behind each of the gears 5, 7 hides each a second gear 6 or 8, as is apparent from Fig. 2 (in the figures 2 and 3, a portion of the gear 7 is omitted for illustrative purposes was).
  • the differential gear, consisting of the gears 5, 6 is for a (for example upper) end position of the blind provided while the Differential gear, consisting of the gears 7, 8, for the other (For example, lower) end position of the blind are provided.
  • the number of teeth the gears 5, 6 and 7, 8 are slightly different.
  • the gears 5, 7 each 40 teeth and the gears 6, 8 each 41 teeth.
  • the gears 5, 6 and also the gears 7, 8 are therefore different driven fast.
  • Each gear 5-8 is each about a not further explained slip clutch connected with an associated switching disc 9-12, as is apparent from Fig. 2.
  • the switching disk 9 is the gear 5, the switching disk 10 the Gear 6, the switching disk 11 the gear 7 and the switching disk 12 the Gear 8 assigned, on the one hand the switching discs 9, 10 and on the other the discs 11, 12 are immediately adjacent.
  • the switching arms 13, 15 are fixed to two on the base plate 2 Axles 17, 18 rotatably mounted.
  • the switching arm 13 acts on a not Bearing lever described in detail on a switch plunger 19 of a microswitch 20 a, which interrupts the current for the electric motor in the one end position, during the switching arm 15 via a non-descriptive lever on a switch plunger 21 of a second, not visible in Fig. 1 and acting under the micro switch 20 microswitch acts, the Electricity for the electric motor in the other end position interrupts.
  • Each indexing disc of the indexing discs 9-12 is on its periphery with a Notch, to which according to the invention a circumferentially extending, axially recessed shift gate connects. Exemplary is only the Shift disc 11 described; the other discs 9, 10, 12 are corresponding educated.
  • the indexing disk 11 of FIG. 2 is shown in Fig. 5 from below.
  • This switching disc consists of a circular disc 22 in the shift gate 25th is trained.
  • This shift gate is as the adjacent switching disc 12th towards open groove 26 to create an arcuate, radially outward lying groove wall 27 is formed.
  • the height of the groove wall 27 is around at least half the width of the web of the switching arm (which is in Fig. 6 the Width of the groove wall 27) dimensioned smaller than the width of the peripheral flange 23rd
  • a switching arm 15 is shown by way of example in FIGS. 7 and 8.
  • the Heidelbergarmspitze 28 of the switching arm 15 is the shift gates 25 such adjusted that after engaging in the notches 24 for the direction of engagement the switching discs 11, 12 held in the shift gates 25 remains.
  • the switching arm tip 28 consists of two laterally outwards standing webs 29, 30 and extending in the longitudinal direction of the switching arm 15 Guide bar 31. Between the switching arm 15 and the web 29 is a groove 32 recessed, in which the groove wall 27 upon engagement of Wegarmspitze 28 place finds. The web 29 glides on the bottom of the groove open groove 26. As not shown, the leadership of the switching arm takes place in the other switching disc 12 in a corresponding manner.
  • FIG. 3 shows, the guide web 31 between the groove walls 27 of the adjacent Shift discs 11, 12 out.
