Definitions

  • the present invention relates to spring motors for toy vehicles and more particularly those whose reassembly is effected by subjecting the toy to 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 an axle which is not capable of being tilted laterally with respect to the engine because it pivots in holes in an oscillating stirrup relative to the flanges, which only allows it to be displaced. parallel to itself.
  • the motor comprises an inversion pinion moved 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 of the wheels.
  • Such an engine is for example described in patent FR-A-2093446, but it is of complicated construction which considerably increases its cost price.
  • the present invention aims 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 over at least one phase of its reciprocating movement, and which presents only a limited number of oranges intended for reassembly so that it is economical.
  • the toy vehicle engine according to the invention is provided with a body and wheels, this engine comprising two lateral flanges, a driving axle of which at least one bearing is elastically movable relative to one of the flanges and a spiral spring of which the tension is obtained by rolling the toy in at least one direction of movement while resiliently lowering its body relative to the drive axle, said engine also comprising first and second teeth set on the drive axle, a winding wheel linked to the inner end of the spiral spring by its axis and capable of being driven by said first toothing when the bodywork is lowered relative to the axle and a train of cogwheels suitable for propelling the vehicle and still in engagement with the second toothing, said motor further comprising a cage enveloping the spring and provided with an external toothed crown, one of the bearings of the driving axle being fixed on a fla while its other bearing is carried by the end of an elastic arm secured to the other flange, this other flange being provided with longitudinal pins on which the body rests, so that the lowering
  • 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 present a lower arm 1a which an axle 3 passes through with functional clearance 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 1a has sufficient elasticity to allow the vertical displacement of the axle at the level of the flange 1.
  • this flange has a notch 1 b located above the axle, as well as a stop 1 c 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 On the axle 3 is angularly wedged a pinion 7 with two teeth, one of which 8 with a large module is located against the inside face of the arm 1a of the flange 1, while the other 9 with a fine module is located near the face inside 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 inside of the cage 12 is provided with notches 12b in the which is placed the outer end 13a of the spiral spring 13. So when the latter is tensioned it causes the set of cogs 9-10-11-12a and the axle 3.
  • the mechanism for banding the spring comprises, in addition to the toothing 8, a sliding pinion 14, the axis 15 of which can move in oblique slots 1d d and 6a formed respectively in the flange 1 and the plate 6.
  • the cage 12 is angularly fixed on an axis 16 relative to which is mounted idly a winding wheel 17 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 1e of the flange 1, while a pin 1f limits the movement of said pawl.
  • the lower part of the flange 1 is provided with two opposite longitudinal journals referenced respectively 1g g and 1 h while an elastic tab 1i extends perpendicular to said flange in the direction of the other flange from the origin of the journal 1 h.
  • this tab could be oriented longitudinally.
  • the axle 3 receives drive wheels 19, 20 so as to drive a toy vehicle whose body 21 has been shown in broken lines.
  • the toothing 8 rotates counterclockwise so that its action on the pinion 14 displaces its axis 15 in the light 1d 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 I otation 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. via the gear train 9-10-11-12a. It will be noted that 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 reassembly, 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 the present 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 into the lumen 1 d.
  • the facing faces of the pinions 14 and 25 are completely smooth and rub against one another.
  • 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 1a carries a terminal lug 1j while the flange is provided with a corresponding projection 1k.
  • the lug In position of rest the lug is below the projection 1 k.
  • 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 1a 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 wheel drive control is carried out strictly as described with reference to FIGS. to to 4 by means of the gear train 9-10-11-12a.
