Definitions

  • the invention relates to a directional lock for a time switch, via 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 moment of resistance than in the other direction of rotation,
  • the directional lock consisting of two plastic parts, namely one with an internal toothing gear which is connected to the drive part and with a pawl body which is coaxial with the internal toothing and which is provided with at least two arms lying in the plane of the gearwheel which are provided with pawls which in the radial direction are at different angles to one another on the tooth flanks of the pawls, engage 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, cf. e.g. DE-A-33 20 242.
  • 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 at different distances from the respective latch tip.
  • This directional lock is provided with the considerable disadvantage that, when rotated in one or the other direction of rotation, initially no adjustment of the time switch part to the drive part takes place, but only that the latch arms are deflected in the area of the front cross-section thinning and only after exceeding a certain angular path do 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 into 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 at an angle smaller than the other tooth flank at a radius R relative 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, which 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 essentially consists of the pawl body 4 and the toothed wheel 7 provided with an internal toothing 6.
  • the pawl body 4 is expediently provided there with two spring-elastic arms 10, which are arranged on one side and are opposite one another by 180 °, and which taper conically from the root 11 toward their free end and are each end-end equipped with pawls 2, which are resilient with the internal toothing 6 of the gear 7 are engaged.
  • FIG. 2 shows an embodiment of a directional lock with a pawl body 4 with two pawls 2 lying opposite one another, which are each fastened to the pawl body 4 via two diametrically opposed 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 region 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 17 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 a corresponding 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 differ from one another at an angle.
  • FIG. 3 A further embodiment, in particular of a pawl body 4, is shown in FIG. 3.
  • the diametrically extending arms 10 are positioned relative to one another in such a way that the respective angles of attack that the outer sides 18 of the arms 10 assume relative to each other with respect to the radius R, the tooth flanks 1 and 8 form a jack immediately.
  • the other ends of the arms 10 are, in particular, radially attached to the latch body 4 in a cohesive manner.
  • 6 shows the internal toothing of the gearwheel 7.
  • three spring-elastic arm pairs 10 are expediently arranged on the latch body 4 at an angle of 120 ° to one another.
  • 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.
