Definitions

  • the present invention relates to a flying toy able to move in the air by flapping its wings, imitating the flight of a bird whose said toy can advantageously have the appearance.
  • a flying toy of this kind described in FR-A-1,604,345, comprises: - a hollow body of elongated shape executed in two parts assembled by interlocking and in the front part of which is housed an actuation mechanism of the wings moved to the by means of an elastic strap providing the driving force; - Two flexible wings fixed, on the one hand, to said actuation mechanism and, on the other hand, to said body; - a winding system making it possible to twist the engine rubber and installed at the rear part of said body which also carries a steerable tail blade serving as a rudder; - And a locking device or stopper to neutralize the wing actuation mechanism during reassembly and before the flight control.
  • the wing actuation mechanism is installed in the body, at the socket, and this mechanism comprises two oscillating levers or wing feet passing through two lateral openings which the said body presents in front of said socket, these oscillating levers or wing feet being connected or intended to be connected, each, to a wing beam on which is fixed the front edge of the flexible wing constituting the wings of the flying toy.
  • flywheels of the aforementioned kind the flapping of the wings ensuring the sustenance of the flying toy ceases when the motor elastic is completely relaxed.
  • the rhythm of the wing beats decreasing with the torsional torque of the motor elastic it happens that these beats cease, as a result of the complete relaxation of the latter, while the toy is at a short distance from the ground or has just make contact with it, allowing a soft landing of the toy.
  • the object of the invention is in particular to remedy these drawbacks.
  • this objective is achieved by a device according to which the retainer is applied, under the effect of an elastic pressure, against the periphery provided with a notch circular plate of the drive crank of the wing actuation mechanism, so that when the elastic of the engine develops its normal power under the effect of the torque, the retainer cannot engage and be maintained in this notch, while when this power approaches its lowest value, at the approach of the complete detorsion of said elastic, said stopper can engage and remain in said notch, causing the stop of the wing actuation mechanism and the immobilization of the latter; the locations of the active part of the retainer and the notch in the kinematic chain of said mechanism, being preferably determined so that the engagement position of said retainer and of said slot corresponds to the position of the wings allowing the flight plane.
  • the torsional torque resulting from the energy released by the unwinding of the driving elastic and from the resistance opposed by the wing flapping mechanism is used to cause the deformation of a flexible portion of the cylindrical wall of the plate of the drive crank and the narrowing of the notch or slot of variable width which said cylindrical wall has, so as to prevent the engagement, in this slot, of the tooth constituting the active part of the retainer which an elastic member tends to push permanently against the periphery of said plate, until the value of the torsional torque decreases, when the elastic is fully relaxed, which allows said plate to resume its form of rest and the increase in the width of said slot in which can then engage and maintain the tooth of the retainer in p revoking the stopping of the flapping of wings.
  • the flying toy always ends its gliding flights, which allows it to land smoothly.
  • the wing actuation mechanism is always locked by the stopper, and it is therefore not necessary to manipulate this stopper before proceeding with a new one. reassembly of the drive system of said mechanism by the rotation of the crank arranged at the rear part of the toy body.
  • the flying toy to which the invention relates is of the kind comprising a hollow body 1 of elongated shape, executed in two parts assembled by interlocking, this body usually being made of plastic.
  • this body In the front part of this body is housed an actuation mechanism of the wings designated as a whole by the reference 2 in FIG. 1 and moved by means of an elastic strap providing the driving force.
  • This mechanism makes it possible to communicate identical oscillations to wing feet 3 placed through lateral openings 4 formed in the body 1 and the external parts of which are connected or arranged so that they can be connected, for example by interlocking, to the beams or wing spars 5 on which is fixed the front edge of the main wing 6 constituting the flexible wings of the toy and whose rear edge is secured to said body, by hooking on a lug, by gluing or otherwise.
  • a winding system 7 making it possible to twist the elastic motor strap is installed at the rear part of the body 1 which also carries an adjustable tail blade 8 acting as a rudder.
  • the wing actuation mechanism 2 installed in the rear portion of the front part of the body 1, comprises a rigid annular frame 9 conforming to the transverse profile of said rear portion.
  • This frame ( Figure 4) is provided, on its periphery, with at least one lug 10 housed in a notch 11 provided in the body 1, so as to cooperate in the immobilization of said frame inside the latter.
  • the flexible 26 and movable 28 parts have approximately equal lengths and the crank pin 23 of the crank 18 is integral with said movable part 28.
  • the crank plate 22 is mounted to rotate in the fixed cage 39 constituted by a split cylinder, and which opposes the rotation of the deformable crank plate 22 in the opposite direction to that of its functional drive, by forming a braking drum.
  • the slot 25 has a width greater than that of the tooth 33 of the retainer 32, so that, in this situation, the latter can engage in said slot.
  • the tooth 33 of the retainer 32 has a width greater than the minimum width presented by the slot 25 when the flexible part 26 is bent and when the end 28a of the movable part 28 occupies a position close to the fixed edge 38 of said slot, so that, in this situation, the tooth can not engage and be maintained in the slot.
  • the free end of the internal part 32b is provided with lugs 34 and 35 intended to come into abutment against the stops 16 and 17 which limit the amplitude of the pivoting of the retainer 32 in both directions.
  • the wing actuation mechanism further comprises two transmission rods 36 which are articulated, on the one hand, via one of their ends, on the crank pin 23 of the drive crank 18, and, d 'other hand, via their opposite end, on the inner end of the oscillating wing feet 3 mounted, with a pivoting ability in both directions, on the axes 13 of the fixed frame 9 of said mechanism.
  • the wing actuation mechanism which has just been described is arranged, according to the invention, so that when the tooth 33 of the retainer 32 meshes with the notch 25, the external part of the wing feet and, by Consequently, the wing beams 5 engaged in the latter, occupy a position according to which they form an angle of small amplitude above the horizontal (of the order of 10 degrees), this position allowing gliding flight (FIG. 2).
  • the tooth 33 of the retainer 32 is engaged, under the pressure of the spring 15, in the notch or slot 25 of variable width of the plate 22 of the drive crank 18.
  • the wing actuation mechanism is is locked and it is therefore possible to twist the elastic motor strap 20 by means of the crank of the winding system 7, so as to store the energy necessary for flight.
  • the wing actuation mechanism is then unlocked by tilting the retainer 32 by means of the operating lever 32a, so as to remove the tooth 33 from the slot 25, and the toy can then be released.
  • the drive crank 18 is driven in rotation by the elastic motor 20 which tends to return to its original shape, thereby ensuring, by means of the links 36 and wing feet 3, the flapping of the wings 6-6 .
  • the resistance opposed by the movement of the wings to the power developed by the elastic motor generates a torque which causes a deformation of the flexible part 26 of the crank plate 22, so that the movable part 28 of said plate tilts around the hinge 37 and that the flexible portion 28c of said movable part slides on the ramp 29 and that its free end 28a approaches the fixed edge 38 opposite the slot 25, the width of which is thus narrowed. Due to this narrowing, the tooth 33 of the retainer 32 pushed by the spring 15 against the periphery of the crank plate, can not engage in the slot 25 of the latter ( Figure 3).
