Definitions

  • the invention relates to a spring drive, the principle of its operation is described in German Patents 2,019,085, 2,039,265, 21,05,734 and 21,66,490 and its particularly preferred structure is described in German Patent 24 61 625, which relate to inventions by the same applicant.
  • Spring drives of this type are preferably used because of their compact design in very small driving toys.
  • the present invention is based on the object of modifying or supplementing this gear so that it is also suitable for driving slow-moving driving toys or driving toys with modified dimensions or weights can be adapted in a simple manner.
  • this reduction gear can not be integrated into the spring drive according to the German patent specification 24 61 625 without a significant change.
  • the escapement known in watchmaking technology is suitable for the escapement, in which the outlet shaft of the spring drive is connected to a switching or escape wheel that interacts with an oscillating armature, the arms of which alternately engage in the toothing of the escapement wheel.
  • the running speed can be continuously controlled in a certain area.
  • German Patent 376 510 in connection with a clockwork and in German Patent 867 351 in connection with a drive for a film camera.
  • a switchable inhibiting device is proposed according to the invention for a spring engine of the generic type, as specified in the characterizing part of the main claim.
  • the basic idea of the proposed solution is to change the vibration amplitude of the armature interacting with the armature wheel.
  • the inhibiting device according to the invention can be combined with the inhibiting device known per se in clockworks or camera drives and mentioned above, as a result of which there are further possible variations. Structural designs of this combination are characterized by claims 6 to 10.
  • the pendulum-mounted anchor is additionally provided with a pendulum mass, which is preferably attached to the pendulum in a detachable and exchangeable manner.
  • a closed barrel 10 there is a spring, not shown, the spring ends of which are connected on the one hand to the barrel gear 11 and on the other hand to the spring core gear 12.
  • the gears 11 and 12 rotating around one another are connected to one another in terms of gears via a so-called reversing pinion 19, which has the rigidly connected pinions 19a and 19b, and drive pinions 18a and 18b seated on the wheel axle 18 such that a torque is exerted on the wheel axle 18, which corresponds to the difference between the torques emitted by the gear wheels 11 and 12.
  • the arrangement of the gears is also such that the spring in the barrel 10 is tensioned in a certain switching position by rotating the wheel axis 18 in both directions simultaneously from the inner and outer ends.
  • this spring drive mechanism known from the patent specifications mentioned at the outset are mounted between engine plates 14, which are connected to one another via the pillars 16.
  • the complete engine is pivotally mounted on the base plate 60 by means of the pillar 16 located at the front in the direction of travel (on the right in FIG. 1).
  • the barrel 10 with its gears 11 and 12 is rotatably mounted between the plates 14 by means of its axis 15.
  • the running of the spring drive is slowed down, the degree of deceleration being changeable.
  • the escapement according to the invention which consists of an anchor wheel 13 which is fixedly connected to the barrel gear 11 and an anchor 20 which interacts with it (see FIGS. 3 and 4), which in turn connects the pendulum 30 to the pendulum mass 31 via part 33 is.
  • the pendulum 30 is pivotally mounted between the arms 52 of a pendulum fork 50 by means of the pendulum axis 32.
  • the pendulum fork 50 itself is firmly connected to the base plate 60 with anchoring arms 53. However, thanks to its elasticity, it can be deflected to a limited extent perpendicular to the base plate by means of the control bolt 51.
  • This is the purpose of the adjusting slide 40 which is arranged to be displaceable along the base plate 60 by means of the adjusting lever 41. It encompasses the control pin 51 of the pendulum fork 50 by means of a control cam 46, the more precise design of which is shown in FIGS. 5 to 9.
  • control curve 46 causes the pendulum fork 52 and thus the pendulum axis 32 when the adjusting slide 40 is displaced from the position 5 over those according to FIGS. 6, 7 into those according to FIGS. 8 and 9, whereby the armature 20 with its armature arms 21, 24 is increasingly engaged with the toothing of the armature wheel 13, as with FIGS. 5a to 9a is illustrated in detail.
  • tub edges 66 serve primarily to limit the pendulum movement of the armature 20, in particular in its uppermost position, in order to prevent jamming between the armature arms 21 and 24 on the one hand and the armature wheel 13, which leads to a complete blocking of the spring drive or at least an uneven influence of the spring engine drain could result.
  • FIG. 5 shows the inhibiting device in the first switching position, in which the adjusting slide 40 engages with a latch 42 in a first catch 62 of the base plate 60.
  • the abutment surface 45 located on the right side of the adjusting slide bears against a cam 65 of the base plate.
  • the top of the slide valve 40 is equipped with a number of stops 43a to 43f, with which the oscillation amplitude of the pendulum mass 31 is limited.
  • a stop part with stops 34a, b, c and 35a is provided below the pendulum mass 31, which are attached to the underside of the pendulum part 34, that is to say connected to the pendulum mass 31 and which have the abovementioned stops 43a to f in the different switching and vibration positions work together.
  • the pendulum mass 31 rests with the part 34 on the stops 43d, 43e and 43g in such a way that a pendulum movement is not possible.
  • the armature 20, as can be seen above all in FIG. 5a is lowered so far down that it cannot come into engagement with the armature wheel 13 rotating in the direction of the arrow when the spring expires.
  • Armature 20, pendulum 30 and pendulum mass 31 are dimensioned and mounted so that the armature 20 is pivoted slightly counterclockwise relative to the horizontal position, so that it is ensured in the arrangement of the embodiment that the teeth of the escape wheel 13 are not with the arms 21 and 24 of the armature 20 come into contact. Armature 20 with pendulum 30 are held in this position, since the pendulum fork 50, in which the pendulum axis 32 is mounted, is held in the lowest position by means of the right part of the control cam 46 and the control bolt 51 located therein.
  • FIGS. 6 and 6a show the inhibiting device in the second switching position.
  • the adjusting slide 40 is to be shifted from the position shown in FIG. 5 to the right until its catch 42 engages in the second catch 63 and its catch 44b in the cam 65.
  • the pendulum fork 50 which engages with the control bolt 51 in the control cam 46, is raised from the lower position to the middle position.
  • the armature 20 comes into engagement with the armature wheel 13.
  • the armature wheel 13 rotates clockwise, one of its teeth runs onto the inside of the armature arm 21 and pivots it and thus the pendulum 30 with the pendulum mass 31 into the position shown in FIGS. 7 and 7a.
  • the oscillation amplitude of the pendulum is limited by the fact that on the one hand it is connected with the stop 35a on the tongue 35 to the stop 43f of the slide valve 40 (see FIG. 6) and on the other hand with the stop 34a on the stop 43b of the slide valve 40 (see FIG. 7).
  • the armature wheel 13 runs with one of its teeth 13a onto the run-up surface 25 of the armature 20 which drops inwards with respect to the armature 20. Since the tip of the tooth 13a runs onto the run-up surface 25 of the armature 20 at an acute angle, the armature wheel 13 can pivot the armature 20 away with less force.
  • FIGS. 8 to 9 The end position in which the inhibiting device according to the invention unfolds its maximum inhibiting effect is shown in FIGS. 8 to 9.
  • control slide 40 In order to get into this position, the control slide 40 has to be moved all the way to the right until its catch 42 engages in the third catch 64 and its catch 44a in the cam 65 and thus lock the slide in the end position.
  • the assignment of the stops on the slide valve 40 and the pendulum 30 is changed in such a way that the pendulum 30 with the pendulum mass 31 reaches maximum vibration ranges.
  • the pendulum 30 strikes the stop 35e on the tongue 35 with the end stop surface 35a on the tongue 35 and in its left position according to FIG. 9 strikes the stop 43a of the control slide 40 with its stop 34b.
  • the range of vibration is hereby increased to a maximum, which inevitably leads to a slowdown of the pendulum movement and thus the rotational speed of the escape wheel 13 connected to the spring gear 11.
  • the armature arm 21 is provided with a projecting nose 23 which, in cooperation with the inner surface of the armature arm 21, limits the depth of engagement. If the armature arm 21 were to penetrate even further into the interdental space, the armature wheel 13 could come to a complete standstill or at least to an uneven inhibition and thus to a non-circular running of the spring drive.
  • the oscillating mass 31, which is preferably made of metal, is detachably connected to the pendulum 30. This makes it possible to change the inhibitory effect by exchanging the pendulum mass, so that the spring drive, which is otherwise unchanged, can be used to drive toy cars of different weights or different designs. This is of great importance for efficient production.
  • the inhibiting device according to the invention can be installed, for example according to the German patent 24 61 625, with slight alteration of the spring engine being manufactured.
  • this spring drive described and shown in the German patent specification 24 61 625 only the purely decorative approaches located on the spring gear 1a need to be replaced by the escape wheel 13 and the spring drive subsequently with the inhibiting device according to the invention, consisting of anchor 20, pendulum 30, adjusting slide 40 and pendulum fork 50 to be supplemented, only minor changes to the base plate 60 being necessary.
  • An advantageous side effect of the inhibiting device according to the invention is that it generates a noise when the spring drive runs off, which is similar to the engine noise, which increases the attractiveness of the toy vehicle for children.
