    [0001] The invention relates to a mechanism for arming / disarming a sliding part, in particular for a toy wheel and jumper having a pair of wheels disposed on either side of a toy body, of the type for example described in FIG. JP 2011/41696 A (Barse), and also relates to such a toy incorporating such a mechanism. The aforementioned document describes a remote controlled rolling object and jumper mounted on two independent wheels each driven by a motor of their own, which allows the toy to move forward, back, to position in order to jump, etc. The body of the toy comprises a frame connected to the wheels and a sliding element guided on slides, with a spring interposed between the frame and the sliding element. A motor moves the sliding element closer to the frame, which has the effect of gradually compressing the spring and thus accumulating elastic potential energy. The assembly is held in this position by a locking system, which can be released to suddenly release the spring and project the toy above the ground by transforming the potential energy of the spring into kinetic energy, the percussion of the piece sliding against the ground producing, by reaction, the desired bouncing effect. The height of the jump can be adjusted by a variable compression of the spring, to deliver a more or less important energy at the time of the jump. An object of the invention is, in general, to provide a particularly simple and reliable arming / disarming mechanism for varying the energy returned to a sliding part by a spring.
    [0002] Applied to a toy of the above-mentioned type, the invention also aims, without having to modify its basic structure, to make it possible to vary the energy delivered by this mechanism and therefore the energy, and if necessary the direction, of the energy. a leap, choosing for example between a jump in height (for example to raise the toy on a table from the ground), or a jump in length (for example to cross an obstacle, the toy finishing its course at the level of the ground). Another object of the invention is to allow such a toy to shoot with different powers.
    [0003] According to a first aspect, these objects are achieved, according to the invention, by a mechanism for arming and disarming a sliding part, in particular for a jumper and / or shooter toy, comprising: a sliding part movable in translation by relative to a base between deployed and contracted positions; - Releasable means for locking the sliding part relative to the base; resilient means biased between the base and the sliding part; and control means adapted to i) storing progressively potential energy in the elastic means by moving the sliding piece towards a position contracted under the action of motor means, and ii) releasing the energy thus stored by driving the sliding member to the deployed position under the effect of a release of the locking means. The control means above comprise: an arm articulated on the sliding part; - A rotating part rotatably mounted on the base, controlled by the drive means and having an inner cam surface adapted to urge a finger integral with the arm during rotation of the workpiece; and a lock capable of cooperating with a locking arrangement formed on the arm; The control means are able to selectively control the motor means: i) in a first mode where the sliding piece is contracted via the cam surface acting on the arm via the finger, then suddenly released after reaching, by the finger, a release zone formed by the cam surface, during the same rotational movement of the rotating part, or ii) in a second mode where the sliding part is contracted via the cam surface acting on the arm by means of the finger, then locked by the lock acting on the locking arrangement of the arm, then abruptly released after reaching, by the finger, a release zone formed by the cam surface, causing the disengaging the locking arrangement from the latch during a reverse rotation of the rotating part. Note that the term "elastic means" should be understood in the broad sense, and not limited to spring means (as in the example of the detailed description below) where the elastic function is obtained by deformation of a flexible material. This term must be understood as also covering means capable, in other forms, of storing energy and of delivering it, for example in magnetic form by bringing together two magnets having the same pole until they meet, to release the energy when unlocking following the same principle as in the case of a spring. According to various advantageous subsidiary characteristics: the cam surface comprises a traction zone capable of progressively biasing the finger of the arm towards the center of rotation of the rotating part, a first protruding release zone adjacent to the traction zone, and a zone erasing adjacent to the first clearing area; - The lock comprises a detent and the locking arrangement comprises a lug secured to the arm between its pivot point on the sliding part and the finger, the cooperation between the lug and the detent depending on the angular position of the arm, and wherein the second release zone formed by the cam surface is adapted to rotate the arm to disengage the latch lug; the first zone of release of the cam surface is able to pulse the arm in a pivoting manner, during deployment, to allow the pin to bypass the detent; the mechanism further comprises a switch actuated by a movement of the latch caused by the locking arrangement in a contraction phase, and wherein the reversal of the direction of rotation of the rotating part in the second mode is effected in response to actuation of the switch; the sliding part is mounted on the carriage by means of two parallel rods received in respective cylinders, and in which the axis of rotation of the rotating part and the axis of pivoting of the arm are perpendicular to the plane containing the axes of both stems; - The latch is movable in rotation about an axis perpendicular to the plane containing the axes of the two rods and is biased by a spring opposing the force exerted by the locking arrangement in a contraction phase; the release zones are two distinct zones adjacent to each other on the cam surface; and the motor means comprise a single electric brush motor operating in direct current. According to a second aspect, the invention proposes a rolling toy and jumper resting on the ground, of the general type disclosed by JP 2011/41696 A, that is to say a toy comprising: - a wheeled carriage , comprising a carriage and a pair of wheels arranged on either side of the carriage, the wheels being mounted relative to the carriage for rotation about a common axis perpendicular to the main direction of the carriage ; - A sliding part, movable in translation and guided along the carriage between deployed and contracted positions; releasable means for locking the sliding part with respect to the carriage; - First motor means, able to exert on the wheels a rotation torque relative to the carriage; second motor means, able to move the sliding part with respect to the carriage; elastic means biased between the carriage and the sliding part; and means for controlling the elastic means, capable of i) storing progressively potential energy in the spring member by displacement of the sliding piece towards a position contracted under the action of the second motor means, and ii) releasing the energy thus stored by driving the sliding member to the deployed position under the effect of a release of the locking means. In a characteristic manner of the invention, the control means comprise a mechanism as defined above, the base of said mechanism being integral with the carriage.
    [0004] According to various advantageous subsidiary characteristics of this toy: - the sliding part comprises a pad for the ground support of the toy in at least one stable position; in said stable position, the control means are able to release the energy stored in the elastic means so as to provoke a jump of the toy above the ground under the effect of the relaxation of the sliding piece transmitted by the pad; the toy is capable of adopting a firing position where it rests in another stable position, the control means being able to release the energy stored in the elastic means so as to project away from the toy an object in contact with a firing piece integral with the sliding piece; the control means are furthermore capable of selectively controlling the motor means in a third mode in which the sliding part is progressively contracted via the cam surface without reaching a locking position by the lock or a release zone of the the cam surface, then progressively deployed by inverse rotation, thereby gradually moving the pad closer to or away from the contact points of the wheels with the ground and thus vary the angle of inclination of the plate relative to the ground surface. We will now describe an exemplary implementation of the device of the invention, with reference to the accompanying drawings in which the same references designate from one figure to the other identical or functionally similar elements. Figure 1 is a perspective view of the toy according to the invention, showing the different elements which, combined together, constitute its structure. Figures 2a and 2b are side views illustrating the toy of the invention in the position it defaults to, but in two different respective inclinations.
    [0005] Figures 3a-3d are side views illustrating the toy respectively in default position, in inverted pendulum position, in firing position and in the position of taking object. Figures 4a-4d are counterparts of Figures 3a-3d in perspective view representations. Figure 5 illustrates in a side view a mechanism for arming / disarming a sliding part, in particular to drive the toy with different forces. Figure 6 is a front view of the mechanism of Figure 5.
    [0006] Figures 7a to 7e are side views of the toy, illustrating different attitudes of the toy during the contraction and then the release of force from the mechanism according to two different force settings. Figures 8a to 8h are front views of the mechanism, illustrating its different phases when arming / disarming with a first setting. Figures 9a to 9k are front views of the mechanism, illustrating its different phases when arming / disarming with a second setting. In Figure 1, the reference 10 generally denotes the toy according to the invention, which comprises a carriage 12 supported by two wheels 14. The wheels 14 are mounted on the carriage 12 to pivot about a common axis D , and they are driven independently by clean electric motors (not shown), controlled by appropriate circuits allowing the toy, according to the direction and speed of rotation of the wheels, to advance in a straight line, to move back, to turn on itself or making a turn, etc., these different evolutions being advantageously controlled by the player by means of a suitable remote control.
    [0007] The carriage 12 extends in a main direction A perpendicular to the axis D of pivoting wheels, and it supports a sliding member 16 displaceable in translation parallel to the axis A under the effect of a suitable motor, driven by the control circuits of the toy. This sliding part comprises for example two parallel rods 18 guided by respective cylinders 20 integral with the carriage 12, with interposition between the rods 18 and the cylinders 20 of one or more springs (not visible in the figures) serving as a means of energy storage, with compression of the spring when the sliding piece 16 is moved closer to the carriage 12, and inversely restitution to the sliding part 16 of the energy stored by these springs when the sliding piece 16 is released to an extended position of the carriage / slide assembly. Note further that in the fully extended position of the slider, the end thereof protrudes beyond the circumference of the wheels 14, and can come into contact with the ground.
    [0008] The carriage 12 is integral with the body 22 of the toy, which itself is provided with a protrusion 24 projecting beyond the diameter of the wheels 22. The distal end 26 of this protrusion 24 comprises, typically invention, a surface 28 directed towards the back of the toy (that is to say to the left with the convention of Figures 1 and 2), on the same side as the extension of the sliding part 16. This surface 28 constitutes a first jaw or jaw of a clamping device which will be described later, in particular with reference to Figure 3d. The protrusion 24 also carries at its distal end 26 a bearing element such as an edge 30 which can form a first contact pad with the ground in a configuration which will be exposed below, in particular with regard to Figures 3c and 3d . Furthermore, the distal end 32 of the sliding piece 16, which protrudes beyond the diameter of the wheels 22, is provided with a second jaw member 34 disposed substantially opposite the surface 28 forming first bit. In the figure, this element 34 has been illustrated in the form of a removable arch, but this particular form is given only by way of non-limiting example. The distal end 32 of the slide member 16 also includes an element 36 such as a ground-facing surface or ridge in the configuration of FIGS. 1 and 2, which forms a second contact pad, capable of forming a point for the toy, in the position illustrated in FIGS. 1 and 2. The toy may also be provided with one or more optical devices 38 (FIG. 4a) such as a camera or a light, whose optical axis forms a fixed angle with respect to the main direction A of the carriage and the body of the toy integral with this carriage. This device allows for example, when the toy moves while driving, to illuminate the front of the toy and / or to capture a video image of the maneuvering ground, seen from the toy. Figures 2a and 2b (as well as Figure 3a, similar to Figure 2a) illustrate a so-called "default" position among several positions that the toy is likely to take, the other positions being described below with reference to the Figures. 3b to 3d. In this position, the toy rests on the ground 42 by three points of support: the two contact points 44 of the wheels 14, and the second contact pad 36 at the distal end of the sliding part 16. As it is indicated above, the sliding part 16 forms a telescopic assembly with the carriage 12, and can therefore move in translation between a deployed position 40 (FIG. 2a) and a folded position 40 '(FIG. 2b) under the action a motor driven specifically to ensure this translation. The displacement of the sliding part 16 produces a displacement of the bearing point on the ground by the second shoe 36 and, correspondingly, a modification of the inclination of the axis A of the carriage, and therefore the inclination of the toy and various elements related thereto: it is possible in this way to adjust the orientation in site of the axis 8 of the camera 38, the orientation in azimuth resulting from the rotation of the toy on itself when the two wheels 14 are trained in opposite directions. On the other hand, the default position 40 or 40 'is that in which the toy is ready to jump (jumper position), by sudden expansion of the springs mounted between the sliding part and the carriage and which have been previously compressed. It is possible to favor a long jump or a high jump by positioning the toy with a greater or lesser inclination of the axis A: for example, the position 40 of Figure 2a with a slightly inclined axis A will favor the length of the jump, while the position 40 'of Figure 2b with an A axis much more inclined upwards will favor the height of the jump. Figures 3a to 3d, as well as Figures 4a to 4d which are similar but viewed in perspective, illustrate the different positions that can take the toy of the invention.
    [0009] Figures 3a and 4a correspond to the "default" position that has just been described with reference to Figures 2a and 2b. This is a naturally stable position, where the toy rests on the ground by three points of support (the contact points 44 of the wheels and the second shoe 36). This position allows, in particular, taxiing, rotations, obstacle clearance, etc., and also constitutes the preparatory position for the jump, as described above, by sudden release of the energy of the springs (shown schematically by the arrow 46) via the second shoe 36, this energy being transmitted, by inertia and reaction of the ground, to the body of the toy to cause the jump of the latter. Figures 3b and 4b illustrate another position 48, called "inverted pendulum", where the protrusion 24 of the toy body is turned upward, as well as the distal end 32 of the slider 16. In this position 48 there is no third fulcrum, and the toy rests solely on the two contact points 44 of the wheels 14 with the ground. Furthermore, the relative position of the sliding part 16 relative to the carriage 12 is not of particular importance in this inverted pendulum position, where the jaws 28 and 34 have no functional destination, nor do they the contact pads 30 and 36, no release of energy being further provided in this position. The position 48 inverted pendulum can be reached from the position 40 by rotation of the toy body (arrow 50), this rotation resulting from a sudden acceleration control backwards: by inertia, the wheels do not move almost not and it is therefore the body 22 which pivots about the axis D. In this position 48, the center of gravity of the toy is located above the axis D, so that the position is naturally unstable and not can be maintained only by servocontrol of the wheel drive motors on the signal delivered for example by an orientation sensor or an inertial sensor incorporated in the body of the toy. This position 48 can be an intermediate position, waiting for selection of an action or the transition to another position (such as the positions shown in Figures 3c and 3d), or a game position in its own right, with the possibility of rolling , rotation, etc., always servo-controlled from the inertial sensor to maintain the body of the toy in equilibrium in the illustrated position during these movement sequences. Figures 3c and 4c illustrate another position of the toy, called "shooter" or kicker. This position 52 is obtained from the default position 40 or the inverted pendulum position 48 by rotating the body (arrow 54) in the same manner as to reach the position 48, i.e. by a sudden acceleration control towards the rear causing, by inertia, the pivoting of the body of the toy around the axis D, the wheels hardly move.
    [0010] This position is a naturally stable position, because the toy rests on the ground on three points of support, namely the two contact points 44 of the wheels 14 and the first shoe 30 of the protrusion 24 secured to the body of the toy and the a skid, which has come into contact with the ground at the end of rotation 54.
    [0011] It will be noted, however, that in an alternative embodiment, it would be possible to omit the projecting portion or protuberance 24 of the body of the toy (and therefore the first contact pad 30), the third bearing point being then constituted by the distal end protruding from the slider 16, or by the stirrup forming the second jaw 34, if such a stirrup is mounted on the end of the slider. In the position 52, the second shoe 36 and the second jaw 34 are placed frontally, which allows to orient them facing an object (symbolized by the cube 56) which can be used as a projectile when the energy of the springs will be suddenly released. after these have been compressed by translating the slide member 16 from its deployed position to its folded position. The release of the springs and the sudden return of the slider to the deployed position has the effect of transmitting the energy of the springs to the object 56 via the second shoe 36 and / or the second jaw 34 (arrows 58). Note that the compression / expansion process of the springs is the same as for the jump function, but here the energy stored by the springs is transmitted to an external object to expel it away from the toy, instead of the toy that is expelled by reaction of the ground. Figures 3d and 4d illustrate yet another possible position of the toy, called "seizure" or grabber.
    [0012] This position 60 is generally the same as that of the sniper position 52, with the only difference that the slide piece 16 is now in its extended position instead of being in its folded position, and that there will be no use of the sudden release of energy. Indeed, in the gripping position 60 the variable stroke of the sliding piece (during the compression of the springs) is used to grip an object (symbolized by the cylinder 62), this action resulting from the progressive translation of the second jaw 34 towards the first jaw 28 (arrow 64), here towards the sliding part 16 from its deployed position to its folded position. Note that the nip remains moderate, the energy developed by the motor for the translation of the slider 16 is essentially absorbed by the springs. As illustrated, it is also possible to provide for the second jaw 34 a flexible arch, whose elasticity will prevent excessive compression of the object 62.
    [0013] The seized object can then be moved, deposited at another location (releasing the nip by a reverse movement of the slider 16), etc. It should be noted that, although the two positions just described are referred to as "shooter" or "seizure" positions, these denominations are in no way limiting and that other interactions than shooting or seizures are quite conceivable. This position (52 or 60) should simply be considered as a particular position allowing similar or different interactions at the default position, and as a position where the toy rests in stable equilibrium on both wheels with the distal end of the piece slider directed towards the ground, with the second jaw movable in a controlled manner parallel to the ground away from or approaching the first jaw. An example according to the present invention of a mechanism for moving the sliding part with arming / disarming will now be described in detail with reference to Figures 5 and following. Note that in these figures elements or parts identical or similar to those of the preceding figures are designated by the same reference numbers increased by 100. This mechanism according to the invention, generally designated by the reference 100, comprises at one end a part slider 116 having at its free end a shoe 116a and on which are fixed rigidly two rods 118 slidably received in two cylinders 120 integral with a base 102 of the mechanism, itself secured to the carriage. Two springs 122 are respectively placed around the two rods 118 and their respective cylinder 120, resting at one end on a shoulder 116b formed on the slide member 116 coaxially with the rod 118 at the root thereof. , and at the opposite end on a shoulder 104 formed at the cylinder 120 opposite its orifice through which engages the respective rod 118.
    [0014] These springs are intended to store energy, with compression of the springs when the sliding part 116 is moved closer to the base 102 of the carriage, and inversely restitution to the sliding part 116 of the energy stored by these springs when said slider 116 is released to an extended position.
    [0015] Furthermore, an arm 130 is hinged about an axis 132 on the sliding piece 116 in the region of one of its ends, and has a finger 134 in the region of its opposite end and a pin 136 in a intermediate region, for purposes explained below. The arm 130 can pivot in a plane parallel to the sliding plane of the sliding part 116 about the axis 132. A generally disk-shaped rotating part 140 is pivotally mounted on the base 102 about an axis 142. parallel to the pivot axis 132 of the arm 130. This rotating part defines an inner cam surface 144 adapted to cooperate with the finger 134, which is applied against said cam surface under the effect of the force produced by the springs. 122 by holding the trapped slider 116. The part 140 is driven by appropriate motor means, preferably a stepper motor (not shown). The motor is driven one way or the other in response to a control unit driving this motor. In particular, as will be understood from reading the description below, the invention can be implemented with a simple electric brush motor "brush" operating in direct current, so with a very simple control logic, this a single and simple engine, however, sufficient to perform all the operations necessary for loading, locking and releasing the stored energy. The cam surface 144 comprises a plurality of zones, as will now be described in detail with reference to FIG. 6 and with reference to the angular position of the rotating member 140 and the distance of the finger 134, supported on the cam surface. , relative to the center of rotation O of the workpiece 140, defined by its axis 142. A first zone 144a is an area whose distance to the axis 142 decreases progressively, when the rotating part 140 rotates in the direction of the needles. a watch in Figure 6, between a point A of maximum distance from the center O and a point B. It thus forms a traction zone for the sliding part, against the force of the springs 122, when the piece turn in this direction. Beyond this point B and up to point C forming an edge, the cam surface forms a notch 144b of generally semicircular shape, in which the finger 134 is adapted to be housed as will be detailed in the after. Beyond the point C, between the points C and D, the cam surface 144 forms a second notch 144c of generally semicircular shape, generally centered on the point O, to accommodate the screw 142.
    [0016] The next area 144d is a slightly domed area, generally radially oriented away from the point O, to a point E forming another edge. Between the points E and F is defined a segment 144e which progressively moves away from the point 0 as the rotation proceeds, the point F forming a bend and a convexity with the following zone 144f where the approximation with the periphery of the part The points G and H define a cradle 144g for the finger 134, the point H being at the same radial distance from the point O as the point A. The zone 144h is thus a circular sector. centered on the point O.
    [0017] The shape of the cam surface 144 as shown precisely in Figure 6 is to be considered as part of the present description. The mechanism 100 further comprises a pawl 150 pivotally mounted on the base 102 about an axis 152 parallel to the axis 132 and the axis 142, this cleat comprising a notch 154 adapted to cooperate with the lug 136 integral of the arm 130, and being urged in rotation clockwise in FIG. 6 by a spring, for example a helical or spiral spring, whose point of attachment on the pawl is designated by the reference 156. The pawl also comprises a working surface 158 able to urge a fugitive switch 160, the two terminals of which are connected, not shown, to the control unit. Advantageously, the arm is made with two generally flat and spaced parts 130a, 130b (see Figure 5), and the lug 136 extends transversely between these two parts, while the pawl 150 is made in the form of a piece of metal. a thickness less than the distance between the two parts 130a, 130b to be able to partially penetrate the space defined between said two parts and to cooperate with the pin 136. Figures 7a to 7e represent the different attitudes of the toy when the slider 116 is in an expanded state, then contracted, then suddenly released under the action of the springs 122 in the jump position. Thus, FIG. 7a illustrates the situation where the sliding part 116 is deployed to the maximum, the toy resting on the ground stably by its two wheels 22 and by the shoe 116a of the sliding part, with an angle between the sliding axis. A and the soil of the order of 25 to 40 °. As the sliding piece 116 is progressively contracted as will be seen below, the equilibrium position of the toy gradually changes to an intermediate position illustrated in FIG. 7b, where up to a position as illustrated in FIG. 7c, where the angle between the axis A and the ground is maximum and for example of the order of 80 to 85 °. Figures 7d and 7e illustrate the initial phase of a jump of the toy in a direction which is generally that of the axis A, this jump being caused by the sudden release, as we shall see in the following, of the energy accumulated by the springs 122 of the moving mechanism 100. Thus, Figure 7d illustrates an almost vertical jump from the position shown in Figure 7c, while Figure 7e illustrates a more elongated jump, made from the position shown in Figure 7b. We will now explain how the displacement mechanism 100 whose structure has been described above can selectively arm the sliding piece 116 to a maximum contraction position (making it possible to reach the attitude of FIG. ) and release it, to make a jump illustrated in Figure 7d, or arm the sliding piece 116 to an intermediate contraction position (to achieve the attitude of Figure 7b), then release it also, to make a jump shown in Figure 7e. The first case is illustrated in Figures 8a to 8h, while the second case is illustrated in Figures 9a to 9k. Note that in these figures, many reference signs as shown in Figure 6 have been omitted so as not to overload these figures, whose scale is smaller than that of Figure 6. Note also that that in the views of Figures 8c, 8d, and 9c to 9k, the arm 130 has been shown partially broken away in order to see the pawl 150 and its different positions. In Figure 8a, the position of the rotating part 140 corresponds to that of Figure 6, the finger 134 of the arm 130 being located at the point A of the cam surface 144. The rotating part 140 being driven in the direction of clockwise in the figures, the finger is gradually attracted by the area 144a of the cam surface towards the center O (FIG. 8b), until it reaches the notch 144b situated between the points B and C (FIG. 8c ). During this movement, potential energy accumulates in the springs 122. Note that in the vicinity of this orientation, the pin 136 biases the pawl 150 at its notch 154 to rotate it in the direction counterclockwise against the force exerted by its own spring, the work area 158 pressing the operating portion of the switch 160. The rotation by the electric motor continues, the notch 144b is gradually moving towards the right in the figures, to gradually rotate the arm 130, also in the direction of clockwise (Figures 8e and 8f). From a certain angular position intermediate those of FIGS. 8f and 8g, the notch 144b is no longer able to retain the finger 134 of the arm 130, and under the effect of the traction exerted by the springs 120, the finger ejects from the notch 144b, released by crossing the C constituting a release zone, by suddenly urging the arm to the right (Figure 8g). The finger 134 being released, the energy accumulated by the springs 122 in the previous phases is also released to violently propel the slide member 116 to its deployed position, thereby causing the jump illustrated in Figure 7d. It will be noted that the zones 144c, 144d, 144e and 144f of the cam surface constitute an erasure zone making it possible not to hinder the aforementioned release.
    [0018] The rotation of the electric motor is continued to complete the rotation 360 °, the position of Figure 8h corresponding to that of Figure 8a. It will be noted here that it is thanks to the rotation of the arm 130 so that it takes the inclination illustrated in FIG. 8g, or a more pronounced inclination, that the lug 136 can bypass the notch 154 of the pawl 150 when - bending, so as not to hinder the deployment in question. Referring to Figures 9a-9k, we will now explain the different phases adopted by the displacement mechanism 100 to achieve an intermediate contraction of the slider 116, and therefore a more elongated jump as shown in Figures 7b and 7e. Figures 9a to 9c correspond to Figures 8a to 8c, the positions of the different elements being the same. Between the positions of Figures 9c and 9d, the pawl 150 pivots progressively under the action of the lug 136 on the notch 154, and in Figure 9d, the switch 160 is closed under the action of the work area 158 of the ratchet. This closure is detected by the control unit of the electric motor and, in response thereto, the rotation of the rotating part 140 is first continued over a small angular extent to the position of FIG. 9e, to ensure that the lug 136 completely cross the notch 154 as shown in this Figure. After this phase, the direction of rotation of the rotating part by the electric motor is reversed, as illustrated by the arrow of FIG. 9f, and the finger 134 of the arm 130 is thus allowed to move away from the center of rotation O, but this movement is interrupted by the abutment of the lug 136 against the top of the notch 154, as shown in this same Figure 9f. This situation corresponds to a contraction of the slider less than that obtained in the operating mode of Figures 8a to 8h, the corresponding stable position of the toy being that of Figure 7b. The rotation in the opposite direction of the clock continues (FIGS. 9g and 9h), the finger 134 of the arm, which can no longer follow the cam surface due to the action of the notch 154 on the pin 136 , leave this surface until the area of the cam surface 144 adjacent to the point D urges the finger 134 to the right in the figures, thereby to pivot the arm 130 about its axis of rotation 134 in the clockwise. FIG. 9i thus shows that the lug 136 is in the immediate vicinity of the free end of the notch 154 and in FIG. 9j, the lug 136 has been released from the notch holding action. The arm thus being released, the energy accumulated by the springs 122 can be released and transmitted to the sliding part 116, and a jump according to Figure 7e is achieved. Finally, counterclockwise rotation is continued to the situation of Figure 9k, which corresponds to that of Figure 9a. The choice between control of the mechanism according to Figs. 8a-8h (near-vertical jump) or in accordance with Figs. 9a-9k (longer jump) is accomplished by receiving corresponding instructions from a remote control device. In the first case, a complete rotation of the rotating part is performed, the rotation of the cam profile being stopped when the inertial unit detects a shock corresponding to the takeoff of the toy. In the second case, the rotating part is first driven in a clockwise direction and then, after detection of the closing of the switch 160, this rotation is extended over a short angular extent and then inverted to return to the original position. It is understood that these two degrees of contraction of the sliding part not only make it possible to generate jumps with different jump orientations, but also to shoot with different forces.
    [0019] Of course, the present invention is not limited to the embodiment described and shown, but the skilled person will be able to make many variations and modifications. In particular, it is understood that by providing on the arm 130 additional lugs associated with respective pawls, it becomes possible to arm the sliding part in different degrees, thereby giving the toy different stable attitudes and, hence, different orientations of jumps.
