Definitions

  • the present invention relates to improvements made to spring motors for toy vehicles and it relates more particularly to those whose reassembly is effected by subjecting the toy to these reciprocating movements on a horizontal plane or the like.
  • Motors of the kind in question are known of which only one end of the spring is connected to the set of drive wheels of the axle, its other end being fixed. In other engines, the two ends of the spring are associated with axle drive cogs. Locks are then provided so that the spring is banded regardless of the direction of advancement of the toy.
  • An engine of this kind has a rigid axle which is not capable of being moved transversely owing to the fact that it pivots in holes in the flanges.
  • the motor comprises a reversing pinion displaced obliquely against the reaction of a spring when the user presses on the body of the toy so that said pinion engages or not with a pinion carried by the axle. wheels.
  • Such an engine is for example described in French patent 71 13965, but it is of complicated construction which considerably increases its cost price.
  • the improvements which are the subject of the present invention aim to remedy the aforementioned drawbacks and to allow the production of a spiral spring motor for a toy vehicle, the reassembly of which is carried out at each phase of its reciprocating movement, and which presents only a limited number of components intended for reassembly so that it is economical.
  • the axle of the wheels tilts under the thrust carried out on the bodywork so that a pinion carried by this axle comes to mesh with the sliding pinion so that the latter actuates a wheel reassembly secured to the inner end of the spiral spring in order to tension it when the toy is moved in one direction, or releases this wheel when the toy is moved in the opposite direction, the rotation of said wheel being then blocked unidirectionally.
  • the motor comprises a second sliding pinion always engaged with an intermediate toothed wheel which meshes with the pinion carried by the axle when the bodywork is lowered so that in a direction of movement the second sliding pinion meshes with the winding wheel, as soon as it emerges from the latter in the opposite direction.
  • a motor according to the invention comprising a set of gears arranged between two lateral flanges 1 and 2.
  • the flange 1 is cut so as to have a lower arm which is traversed with functional clearance by an axle 3 at each end of which the drive wheels of a toy vehicle are propped up and propelled by the engine in question.
  • the flanges 1 and 2 being made of a suitable plastic material, the arm has sufficient elasticity to allow the vertical displacement of the axle at the level of the flange 1.
  • this flange has a notch Ib located above the axle, as well as an abutment lc against which the axle comes to bear at the end of its travel.
  • the axle 3 crosses the flange 2 in an opening allowing its free rotation even in an oblique position.
  • Spacers 4 and 5 maintain the two flanges at a determined spacing while securing between them an intermediate plate 6.
  • a pinion 7 with two teeth one of which 8 with large modulus is situated against the inner face of the arm 1a of the flange 1, while the other 9 with a fine module is located near the inner face of the other flange 2.
  • This toothing 9 cooperates with a wheel 10 which is integral with a pinion 11 meshing with the toothed crown 12a of a cage 12 inside which is housed a spiral spring 13.
  • the interior of the cage 12 is provided with notches 12b in which is placed the outer end 13a of the spiral spring 13.
  • the mechanism for tensioning the spring comprises, in addition to the toothing 8, a sliding pinion 14, the axis 15 of which can move in oblique slots ld and 6a formed respectively in the flange 1 and the plate 6.
  • the cage 12 is angularly fixed on a axis 16 with respect to which a winding wheel 17 is mounted madly attached to a disc 17a which closes said cage. It is observed that a pawl 18 cooperates with the teeth of the wheel 17 so that it can only rotate in one direction (clockwise in the example shown).
  • the pawl 18 is secured to an elastic finger 18a bearing on a fixed point the of the flange 1, while a pin If limits the movement of said pawl.
  • the lower part of the flange 1 is provided with two opposite longitudinal pins referenced respectively 1g and Ih while an elastic tab li extends perpendicularly to said flange in the direction of the other flange from the origin of the pin Ih.
  • the axle 3 receives drive wheels 19, 20 so as to drive a toy vehicle whose bodywork 21 has been shown in broken lines.
  • the body 21 is pressed vertically in the direction of the arrow F (fig. 4). It therefore lowers in the direction of the horizontal plane 22 on which the wheels of the toy vehicle rest.
  • the pins 1g, Ih of the flange 1 of the motor being engaged in 3rd perforations or with respect to open or closed bearings of the body 21, there is a tilting of the motor against the reaction of the lug so that the axle 3 remains pa »parallel to the plane 22 while the arm deforms so that the toothing 8 of the pinion 7 comes in 8 'to mesh with the sliding pinion 14 (fig. 2).
  • the toothing 8 rotates counterclockwise so that its action on the pinion 14 displaces its axis 15 in the light ld in direction of the top thereof so that its teeth are released from those of the wheel 17.
  • the tension of the spring on the latter applies its teeth against the pawl 18 which blocks the rotation of the winding wheel.
  • the train of cogs 9-10-11-12a is driven in the opposite direction with respect to that corresponding to the anterior movement of the toy vehicle so that the cage 12 rotates counterclockwise. If each round trip of the toy is of equal length, the cage 12 performs exactly the same number of turns in one direction and in the other; its antagonistic action with respect to the tension of the spiral spring is therefore canceled. Otherwise it is at least largely compensated.
  • the body 21 After a certain number of back-and-forth movements, the body 21 is released, causing the elastic return to the initial position of the motor relative to the axle 3 so that the energy stored by the spring is transmitted to this axle which becomes motor. with respect to the axle 3 so that the energy stored by the spring is transmitted to this axle which becomes motor via the train of cogs 9-10-11-12a.
  • the relaxation of the spring only takes place at the level of the cage 12 because the reaction generated by the inner end of the spring on the hub of the wheel 17 tends to rotate it in a direction such that the one of its teeth bears against the pawl.
  • the spring In the event of prolonged winding, the spring cannot be subjected to an exaggerated tension which risks causing it to break, because above a certain value thereof, its end 13a slips in relation to the cage 12 by jumping from a notch 12b to the other.
  • the pinion 14 is, in accordance with this variant, mounted in the same way, that is to say that its axis 25 only protrudes in the direction of the flange 1 to penetrate
  • the pinion 17 has a width at least equal to the sum of that of the sliding pinions 14 and 25.
  • the end of the arm carries a terminal lug 1j while the flange is provided with a corresponding projection lk.
  • the lug In the rest position, the lug is above the projection lk.
  • this projection tends to approach the plane 22 on which the toy rests.
  • the projection comes to cooperate with the lug to very slightly deform the elastic arm so as to come below the lug (fig. 7).
  • the elasticity of the arm returns the projection to its initial position (fig. 5). It is thus ensured that the meshing of the pinions is effected positively at the bottom of the teeth.
  • the pinion 8 is provided frustoconical so as to facilitate its engagement with the pinion 24 and the sliding gear 14.
  • the propulsion control of the wheels is carried out strictly as described with reference to FIGS. 1 to 4 by means of the gear train 9-10-11-12a.
