Definitions

  • the invention relates to a directional lock for a time switch, by means of which a drive part drives a time switch part, which can be manually adjusted in relation to the drive part in one direction of rotation against a greater section modulus than in the other direction of rotation,
  • the directional lock consisting in particular of two plastic parts, namely from an internal gear provided with the drive part and a pawl body which is coaxial with the internal gear and which is provided with at least two arms lying in the plane of the gear, which are provided with pawls which are at different angles in the radial direction which on the tooth flanks of the pawls engage in the internal toothing of the gear wheel in a spring-elastic manner and which are pressed out of the internal toothing during adjustment in one or the other direction of rotation.
  • a directional lock for a time switch is known in which the latch arms are each provided with two elastic bending sections formed by radial cross-sectional thinnings, which are at different distances from the respective latch tip.
  • This directional lock is provided with the considerable disadvantage that, in the event of a rotation in one or the other direction of rotation, initially no adjustment of the time switch part to the drive part takes place, but that only a deflection of the clin low arm in the area of the front cross-section thinning and only after exceeding a certain angular path the pawl tips jump out of the internal toothing into another tooth base. It is also disadvantageous here that the cross-sectional thinnings in the material thickness must be kept very precise, because otherwise a simultaneous jump from one tooth gap to the other is not guaranteed. With this directional lock, it is not possible to make a dial-related setting of a switching disc without first having to accept a blind path.
  • the two tooth flanks of the pawls are extremely acute-angled, the tooth flank facing the pawl arm being smaller in angle than the other tooth flank with respect to the radius R in relation to the radius of the internal toothing symmetrical tooth flank course of the internal toothing.
  • This toothing has the disadvantage that the hysteresis-free adjustment in one and in the other direction of rotation due to the relatively acute-angled design of the pawls for the flank angle-symmetrical internal toothing can only be adjusted jerkily, which can cause several teeth to be skipped when adjusting. A sensitive dial-related setting is difficult here.
  • the invention has for its object to provide a directional lock of the type mentioned for time switches that can be adjusted easily and sensitively, based on a scale division of a dial on the time switch part.
  • the directional lock shown in FIG. 1 consists essentially of the pawl body 4 and the toothed wheel 7 provided with an internal toothing 6.
  • the pawl body 4 is there expediently provided with two resilient, oppositely arranged arms 10 arranged at 180 °, which taper conically from the root 11 towards their free end and are each end-end equipped with pawls 2, which are resilient with the internal teeth 6 of the Gear 7 are engaged.
  • the directional lock shown in FIG. 2 consists in detail of the pawl body 4 with the pawl 2, which is fastened to the pawl body 4 with two resilient arms 10 running diametrically to one another.
  • the arms 10 are arranged coaxially and circularly to the pawl body 4. These arms 10 are on a common web 16, which there at an angle of 180 o is arranged offset to the pawl 2, attached to the pawl body 4. 17 denotes the bearing of the pawl body 4 and 7 shows the gearwheel coaxially arranged with the pawl body 4 and having an internal toothing 6.
  • the tooth flanks 1 and 8 of the pawl 2, as well as the tooth flanks 5 and 9 of the gear 7 are each of different sizes, based on the radius R. This diversity of the gradients ensures that in the one direction of rotation has a greater section modulus than in the other direction of rotation.
  • the gear 7 can be connected to a drive part and the pawl body 4 to the time switch part of a timer.
  • FIG. 3 shows an embodiment of a directional lock with a pawl body 4 with two pawls 2 lying opposite one another, each of which is fastened to the pawl body 4 via two diametrically extending arms 10.
  • 6 denotes the internal toothing of the gear 7 with which the pawls 2 are in resilient engagement.
  • the arms 10 are angled radially in the area of their attachment to the pawl body 4 and are each individually attached to the pawl body 4.
  • the arms 10 run in a circle around the bearing point 14 of the directional lock.
  • 15 denotes flat designs in the area of the bends of the arms 10 and in the area of the pawls 2. These designs 15 serve as support points for ejecting the part made of plastic from an appropriate injection molding tool.
  • 1 and 8 denote the tooth flanks of the pawls 2 which differ in the pitch from one another.
  • 5 and 9 show the tooth flanks of the internal toothing 6 of the toothed wheel 7 which are different from one another at an angle.
  • FIG. 4 A further embodiment, in particular of a pawl body 4, is shown in FIG. 4.
  • the diametrically extending arms 10 are positioned relative to one another in such a way that the respective angles of attack correspond to the outer sides 18 of the arms 10, based on the radius R. take each other, the tooth flanks 1 and 8 of a pawl form directly.
  • the other ends of the arms 10 are, in particular, attached to the latch body 4 in a radially extending manner.
  • 6 shows the inner teeth of the gear 7.
  • the lamella thickness of the arms 10 can be approximately 0.5 mm in this embodiment as well as in the previously described directional locking designs.
  • Fig. 5 shows a directional lock with a gear 7, which is provided with an external toothing 12 in a modification of the previously mentioned internal toothing 6.
  • 4 designates the pawl body with three pawls 2 arranged angularly symmetrically to one another, which are each connected to the pawl body 4 via two spring arms 10 running diametrically to one another.
  • the angles of the tooth flanks 1 and 8 of the pawls 2, as well as of the tooth flanks 5 and 9 of the external toothing 12 of the toothed wheel 7, with respect to the radius R, are different in size from one another.
  • angularly symmetrical tooth flanks can be provided both for the pawl 2 and for the gear 7 with an internal or external toothing.
