Definitions

  • the invention relates to a spring drive for toys of the type mentioned in the preamble of the main claim.
  • Such a spring drive is known from DE-PS 24 61 625.
  • the mainspring of this spring drive is tensioned by turning the output / elevator shaft.
  • two gear transmission parts are provided between the output / elevator shaft on the one hand and the ends of the mainspring on the other hand, which are connected to one another via a reversing pinion.
  • the arrangement is such that by rotating the output / elevator shaft in both directions, the mainspring is simultaneously tensioned from the inner and outer ends. If the reversing pinion is held in engagement with both gear transmission parts, the transmission is blocked The mainspring cannot relax. Only when relaxing, e.g. B. Release the depressed body, the reverse pinion axis, the gear lock is released and the toy vehicle can move.
  • the invention has for its object to design this Federtriebwerkso that the spring lock is maintained after tensioning the mainspring and this is only solved by a push against the toy in the direction of travel, whereby the mainspring sequence and thus the driving movement of the toy are initiated.
  • the main solvent here is the detent lever, which releasably holds the reversing pinion axis and thus the reversing pinion in its engagement position blocking the mainspring.
  • the detent lever is in this case in such a way at the reversing pinion axis and the spring drive - movement plate supported to the direction of travel of the toy vehicle corresponding to the direction of rotation in which it is unlocked upon rotation of the driven / elevator shaft, thereby enabling the end of the spring engine.
  • Fig. 1 is a gem. spring engine executed according to the invention, as it can be used in a toy car.
  • the spring drive is arranged to be pivotable to a limited extent about a connecting post 10 in a vehicle body (not shown) in order to transfer the wheel train from a position in which the vehicle wheels are driven by the relaxing spring to one in which the drive spring is rotated by rotating the vehicle wheels in is pulled in both directions.
  • the mainspring is arranged in a barrel 1, which is equipped with a first spring gear 1a.
  • the second spring gear 2a is connected to the spring core shaft 2.
  • the inner end of the mainspring is connected to the spring core shaft 2, while the outer end is connected to the barrel 1.
  • Pinions 5 and 5 ′ arranged on the output / elevator shaft 4 are in engagement with the spring gears 1a and 2a. Between the pinions 5 u. 5 'and the output / elevator shaft 4 each have a directional lock of opposite directional effect, which have the effect that torques generated on the output / elevator shaft 4 are transmitted, depending on the direction of rotation, either to the first spring gear 1a or to the second spring gear 2a.
  • This construction causes the mainspring to be tensioned simultaneously from both ends regardless of the direction of rotation of the output / elevator shaft 4.
  • the vehicle wheels 6 are seated on the output / elevator shaft 4.
  • a reversing pinion 3 can be seen, the first pinion ring 3b of which is only partially visible and is constantly engaged with the second spring gear 2a, while the second pinion ring 3a is disengaged in the positions corresponding to FIGS. 1 to 6.
  • its reversing pinion axis 7a When its reversing pinion axis 7a is depressed, it comes into gear connection with the drive pinion 5.
  • the vehicle wheels 6 rotated clockwise, so the vehicle is pushed against the direction of travel X when the reversing pinion axis 7a is depressed, the drive pinion 5 drives the first spring gear 1a counterclockwise thanks to the formation of the directional lock not shown in the drawing.
  • the mainspring By means of the first spring gear 1a, the mainspring, not shown, is tensioned from its outer end.
  • the rotation of the pinion 5 is simultaneously reversed via the reversing pinion 3, the second pinion gear 3a with the pinion gear 5 and the first pinion gear 3b with the second spring gear 2a, and transferred to the latter, so that the mainspring simultaneously from its inner In the end.
  • the pinion 5 'on the output / lift shaft 4 takes effect, while the drive pinion 5 runs idle relative to the output / elevator shaft 4, so that there are reversed functions and likewise the spring gears 1a and 2a rotate in the same directions of rotation as mentioned above.
  • All shafts of the spring engine are arranged between the two engine boards 8 and 9, which are connected to one another by means of the two connecting posts 10 and 11.
  • the reversing pinion axis 7a of the reversing pinion 3 is part of a curved spring wire with further sections, namely the connecting yoke 7b, the spring leg 7c, the spring turn 7d and a further spring leg 7e.
  • the latching lever 20 in particular its second sprocket ring 3a, holds the reversing pinion 3 against the action of the restoring force generated by the spring legs 7c, 7e in engagement with the drive pinion 5.
  • the transmission blocked in such a way that the tensioned, located within the barrel 1 mainspring can not relax.
  • locking levers 20 and the locking means assigned to them are formed on the drive plate 8 in such a way that the locking is released by turning the vehicle wheels 6 in the counterclockwise direction. Is a provided with the spring engine toy according to the invention z. B. offset manually or by means of an accruing second vehicle in the direction of travel X, the latching is consequently canceled so that the triggered vehicle now starts under the action of its own tensioned mainspring.
  • FIGS. 2 to 7 only the parts essential for understanding the present invention are shown, the structure and mode of operation of which are explained below.
  • FIG. Fig. 1 shows a side view of the spring drive according to FIG. Fig. 1, in which the vehicle wheels 6, the barrel 1 with its first spring gear 1a and the spring core shaft 2 with its one-piece second spring gear 2a are omitted.
  • the side view of the second pinion gear ring 3a of the reversing pinion 3 and the drive pinion 5 are shown, parts which are shown in the illustration according to FIG. Fig. 1 are located behind the engine board 8.
  • the locking lever 20 is pivotally mounted on the end of the reversing pinion axis 7a located in front of the engine board 8 by means of a bore 21.
  • the spring wire 7b to 7e is designed such that a restoring force acts on the end of the reversing pinion axis 7a in the direction of the arrow C.
  • the latching lever 20 engages with a latching lever eye 23 the end of the drive / elevator shaft 4 that projects outward beyond the engine board 8.
  • the output / elevator shaft 4 lies in the lower detent 23a of the detent lever eye 23.
  • a first upper detent 23b is provided within the detent lever eye 23 offset from the second lower detent 23a.
  • the upper catch 23b is slightly resilient thanks to an incision 23c in the catch lever 20, which is made of resilient plastic.
  • the locking lever 20 also has a pin 22 which engages in a slot-like recess 16 of the engine board 8, as shown in FIGS. 4, 6 and 9.
  • the mounting of the reversing pinion axis 7a within the slot-like bearing 13 with its notches 13a, 13b and 13c can also be seen in detail.
  • the second pinion gear ring 3a has to be brought into engagement and held with the drive pinion 5, as is shown in detail in FIGS. 7 to 9, while FIGS. 5 and 6 illustrate the transition position.
  • a force is exerted on the spring leg 7c in the direction of arrow D (see FIGS. 2, 3 and 5) by means of the body (not shown).
  • the spring leg 7c migrates from the rear latching surface 14b of the engine board projection 14 via the latching lug 14c to the guide bevel 14a.
  • This causes the reversing pinion axis 7a to be pulled out of the upper catch 13a of the slot-like bearing 13 via the middle indifferent position shown in FIG. 5 into a lower position which, as shown in FIG. 9, lies between the front catch 13b and the rear catch 13c .
  • the latching lever 20 which is pivotably seated on the reversing pinion axis 7a is inevitably taken along, its pin 22 being removed from the upper latching surface 16b (see FIG. 4). is guided to the lower locking surface 16a via the locking lug 16c in the middle position (see FIG. 6) (see FIG. 9).
  • the locking lever 20 controls by movement of the reversing pinion axis 7a and the pin 22 within the slot-like recess 16, the locking lever 20 performs a slight pivoting movement clockwise, so that the output / elevator shaft 4 within the locking lever eye 23 from the lower detent 23a to the upper, with respect the latter offset latch 23b arrives.
  • the upper catch 23b is offset from the catches 13a, 13b, 13c of the slot-like bearing 13 in such a way that when the restoring spring force takes effect in the direction of arrow C, the catch lever 20 supported at the same time with its pin 22 on the lower catch surface 16a in the position shown in FIGS 7 to 9 remains in the illustrated position, that is to say the drain gear remains blocked by means of the reversing pinion 3. 7 and 8 indicate that the locking lever 20 assumes a position slightly tilted with respect to the engine board 8.
  • a torque in the counterclockwise direction is to be applied to the output / elevator shaft 4 by turning the vehicle wheels 6.
  • the gear arrangement has the effect that the reversing pinion 3 is also rotated in the counterclockwise direction. This is possible since only the pinion 5 'via the directional lock that now takes effect drives the second spring gear 2a clockwise and this drives the reversing pinion 3 via its first pinion ring 3b in the counterclockwise direction.
  • the drive pinion 5 can rotate against the direction of rotation of the output / elevator shaft 4 since the directional lock for this direction of rotation is released.
  • the catch lever 20 can be brought into the starting position according to the catch 23d. 1 to 4 pivot in which the lower catch 23a engages around the output / elevator shaft.
