Definitions

  • the present invention relates to a pulse generator according to the preamble of claim 1.
  • Such a pulse generator is known from US Pat. No. 4,282,415.
  • the gearwheel consists of a disk with pins which project vertically from the front and are arranged at the same distance from one another on a circle.
  • the actuator which can only be moved laterally, consists of a metal band made of resilient material and bent into an elongated rectangle. On one long side of the actuator, a locking projection is formed, which engages in a gap between two pins in the rest position.
  • the gearwheel is locked in the rest position by a special detent spring in that a leaf spring provided with a shape and acting as a detent spring interacts with axially projecting pins arranged on the back of the disks. Due to the fact that the actuator is made of metal, it must be at such a distance from the contacts on both sides in the rest position that a rollover is avoided.
  • the object of the present invention is to design a pulse generator of the type mentioned so that the actuator can connect close to the contact springs or even touch it. Furthermore, the pulse generator should be inexpensive and easy to assemble.
  • the actuator can extend to or close to the adjacent contact spring without the risk of a short circuit.
  • the contact spring is actuated practically immediately when turning the gear, since no space between the actuator and contact spring is necessary.
  • the two-dimensional deflectability of the actuating element makes it possible to vary the spring pressure of the compression spring within further limits than is possible with an actuating element consisting of a resilient metal band. It should be emphasized that a multi-angled metal strip does not reach precisely defined values as a result of the structural changes that occur in the metal, so that relatively large tolerances can occur in a batch of actuators. In addition, no additional return spring needs to be provided.
  • Fig. 1 denotes a preferably tub-shaped or cup-shaped housing part of a pulse generator, which has an outwardly projecting bearing bush 2.
  • a rotary shaft 3 is mounted, on the inner end of which a gear 4 is attached.
  • a guide web 7 in the form of a plane-parallel plate is attached, which was formed during the manufacture of the housing part 1.
  • the plane of the guide webs 7 runs in the direction of the toothing of the gear wheel 4.
  • the guide webs 7 engage with little play in each side slot 8, 9 running in the same plane of a rod-shaped or bar-shaped actuating member 10 made of electrically insulating material.
  • the latter has a downward-pointing, in particular acute-angled latching projection 11, which engages in a tooth gap 13 of the gearwheel 4 under the pretension of a compression spring 12.
  • the compression spring 12 is designed as a wire, rod or leaf spring. It lies in a groove 14 of the actuating member 10 and crosses the roller-shaped elevation 15, which is arranged on the side of the actuating member 10 opposite the latching projection 11. Each spring end 16 or 17 of the compression spring 12 lies on a respective side stop edge 18 or 19 under tension on the latter are formed in the embodiment by the lower edge of the guide webs 7.
  • a contact spring set comprising a movable contact 20 and 21 and fixed normally closed contacts 22 and 23 and fixed switching contacts 24 and 25 are arranged on both sides of the tooth gap 13.
  • the movable contacts 20, 21 are fastened to a leaf spring 27 or 28 anchored in a wall part 26 which can be inserted into the housing part 1.
  • the free end 29 or 30 of the leaf spring 27 or 28 projects beyond the movable contact 20 or 21 and projects into the area of the actuating member 10.
  • two actuating lugs 31, 32 projecting toward the leaf springs 27, 28 are arranged, the respective outer edges 33 and 34 of which, in the rest position of the pulse generator, run at a short distance from the associated leaf spring 27 or 28.
  • actuation approaches 31, 32 a correspondingly broad single actuation approach can also be provided.
  • the pulse generator works as follows:
  • the actuator 10 is first shifted to the left by the right tooth 35.
  • the outer edge 33 of the actuating projection 31 comes into operative connection with the free end 29 of the leaf spring 27 and presses the latter to the left.
  • the normally closed contact 20, 22 is opened and the switching contact 20, 24 is closed. 4 shows this switching state.
  • the catch projection 11 runs up on the tooth flank of the tooth 35, as shown in FIG. 5.
  • the actuator 10 is raised on the contacting side, the actuating projection 31 along the free end 29 of the leaf spring 27 slides upwards.
  • the latching projection 11 jumps over the tip of the tooth 35 and engages in the following tooth gap.
  • the actuating member 10 assumes its rest position and the movable contact 20 springs against the normally closed contact 22. With each deflection of the actuating member 10, the normally closed contact is therefore opened and the switching contact is closed. A positive and / or negative pulse can therefore be generated in each case.
  • FIGS. 6 to 10 Another embodiment of the invention with an appropriately further developed actuator is described below with reference to FIGS. 6 to 10.
  • the same parts as in the embodiment according to FIGS. 1 to 5 are provided with the same reference numerals. 6 to 8 show the same view, but with different functional positions of the actuatable parts.
  • a wall part 26, designed as a contact plate and supporting leaf springs 27 and 28, is inserted.
  • the wall part 26 is provided with locking pins 40 which can snap into corresponding recesses in the housing part 1.
  • An intermediate space 41 is formed between wall part 26 and gear 4.
  • the actuator 10 projects into this with a tab-like extension 42 attached to it.
  • the extension 42 is provided with an elongated hole 44 extending in the direction of a line from the axis of rotation 43 of the gear 4 to a locking extension 11 of the actuating member 10.
  • a bearing pin 45 engages in the latter. This is expediently attached to the rotary shaft 3, in particular molded on.
  • the gear wheel 4 can also be integrally formed on the rotary shaft. This makes the approach 42 um the pivot pin 45 is pivotally mounted and displaceable in the direction of the line described.
  • the actuating member 10 On the side of the actuating member 10 opposite the latching lug 11, the latter is provided with a groove 14 in which a leaf spring 12 bears under prestress.
  • the base of the groove is angled slightly roof-shaped so that an elevation 15 is formed.
  • Each spring end 16, 17 of the leaf spring 12 bears against a stop bolt 46 under prestress.
  • the pulse generator works as follows:
  • the tooth 35 takes the locking projection 11 with it and thereby moves the actuating member 10 to the right.
  • the shoulder 42 pivots about the axis of rotation 43.
  • the projection 48 strikes the leaf spring 28 and deflects it to the right, so that the contacts 21, 25 are closed. 7 shows this state.
