Description

The present invention relates to toy vehicles, and more

  especially, toy vehicles that are rolled back to store energy first, and that roll

  then forward thanks to a release of the energy thus emma-

  gasinée. There are toy vehicles that are designed to store energy when they are rolled backwards, so as to raise a spring. Usually, these vehicles are simply propelled forward as soon as they are released after rolling them in. These toy vehicles are described in

  US-A-4,077,156 and US-A-2,182,529.

  Each toy has a relationship to the reality of life The more a child can identify his toy to the adult world he sees around him, the more he derives pleasure and teaching Thus, a toy vehicle that simply goes forward when we release him is not

  always felt like a vehicle that can be ordered

  if it takes switches, levers, etc., to release a toy, it will probably not more felt like a vehicle of the adult world Moreover, it can be embarrassing and difficult for a child to have a finger at home. below or around a small toy vehicle to operate a lever, etc., without deflecting

  same time the vehicle of his route.

  Therefore, there is a need for new vehicles

  and improved operating in the manner described above and

  The object of the present invention is to provide such a vehicle that can be controlled without levers, switches or other means, apparent and unrealistic. Another object of the present invention is to provide a vehicle of the type described having a safe and reliable operation, which is self-adjusting, so that it does not have to be locked in a state of storage of energy, nor in a state of energy release. According to a characteristic of the invention, there is provided a toy vehicle which comprises a stable two-state mechanism, a spring, and a transmission with an inverter device controlled by the stable two-state mechanism and the spring By rolling the vehicle in In reverse, the energy is transmitted through the transmission and the stable two-state mechanism automatically switches to storage and maintenance of energy in the spring. An action on the stable two-state mechanism unlocks and releases the energy stored in the spring by switching on the reversing device The release of the energy stored in the spring results in a propulsion in front of the vehicle. A preferred embodiment of the invention is illustrated in the accompanying drawings, in which: FIG. 1 is an exploded perspective view of the toy vehicle according to the invention; FIG. 2 is a plan view from above of the two-piece mechanism; stable states of the invention, mounted on a frame, Fig 3 is a top plan view of the toy vehicle in which a panel of the bodywork, or other suitable part, here the hood, is used to release the stored energy 4 is a vertical sectional view along the line 4-4 of FIG. 2 which illustrates the stable two-state mechanism mounted in the vehicle, FIG. two stable states in a first stable position that locks the gearbox and maintains the energy stored in the spring, Fig 6 shows the stable two-state mechanism in a second stable position that unlocks the gearbox and releases the energy stored in the spring, Fig 7 shows the toy vehicle that is rolled back to store energy, and Fig 8 shows how we release the energy stored in

  the vehicle by pressing your finger on the hood.

  Fig 1 is an exploded view of the main subsets of the toy vehicle, these being: a gearbox 20 and a trigger 22 together forming the stable two-state system, a frame 24 and a bodywork 26 The bodywork 26 comprises a cover 29 that has been defined by the double line 28 to show that it pivots in the front to act as a control panel of the release

Energy.

  There are several suitable models for the box 20 which, in this case, may be identical to the gearbox described in US Pat. No. 4,077,156 or that described in US-A-2,182. In general, the gearbox 20 contains a gear train from an axis 30 to a spiral spring 32 A movable pinion 33 is mounted on a shaft 34 which is free to move at one end. to the other of a light 36 of elliptical or elongated shape When the shaft 34 is at one end, here

  the upper end of the lumen 36, the gear train is con-

  connected to the axis 30 and the wheels 38, 40 so that the vehicle rolls forward When the shaft 34 is at the other end, here the low end, of the light 36, the gear train is connected to the axis so as to wind the spring 32 and to store energy when the vehicle is rolled back In short, the gear train is a transmission and the gear is a device

inverter in said transmission.

  Therefore, if the shaft 34 is blocked at one end, here the lower end, of the lumen 36, the gear train is locked in a winding position of the spring or energy storage. shaft 34 is free to go to the other end, upper, light 36, the spring energy is released for

propel the vehicle.

  The rear side of the gearbox 20 has a shoulder

  42 that can be taken under a tab 44 secured to the frame 24 The front side of the gearbox 20 also has a shoulder 46 which comes into contact with the flanges 70, 72 of the trigger 22 The shoulder 46 also comes into contact with a stopper 48, integral with the frame 24, which limits upward the travel of the gearbox 20 The trigger 22 comprises a pair of arms 49 which enclose the gearbox 20 to prevent the stable two-state mechanism from moving laterally The ends of the arms -49 are formed of substantially cylindrical elements 51 which bear on the sides of the speed boot 20 to limit the friction at the ends.

places of tightness.

  The front of the trigger 22 has an opening 50 which fits

  on a latch 52 integral with the frame 24, the latch 52 preventing the trigger 22 to go up Two posts 54, 56 are in loose contact with the sides of the trigger 22 to help keep it aligned In addition, the vertices of the uprights 5 s , 56 are in contact with the base of a transparent piece that they contribute to support, said transparent piece fitting inside the square

  26 to form the windows of the car.

  Consequently, the trigger 22 is free to move up and down between the limits formed by the floor of the frame 24 and the stopper 48. The other bosses of the frame 24 serve to position the body and the front axle 62 on the chassis 24 The front of the body is held by hooks 63, after which the rear of the body is fitted on a reinforced opening 65 through which a self-tightening nut 67 to block and hold everything. The trigger 22 has a pair of uprights 64 which form an integral part thereof. Their height is such that they slightly raise the cover panel 29, when the stable two-state mechanism is locked in the energy storage state. The height of the uprights 64 is such that the two-state mechanism

  stable position is pushed to the low position, Fig 6, in the released state.

  When the downward pressure is applied to the hood 29 the perimeter of the trigger 22 has ribs

  protrude upward to give it strength and rigidity.

  Jumper-shaped power locking means is integral with the frame 24 The jumper is of a height such that it blocks the shaft 34 in the energy storage position (Fig 5), against the lower end of the housing. the light 36, while the box

  speed is raised, the shoulder 46 bearing against the stopper 48.

  When the gearbox 20 rests on the floor of the frame 24, Fig 6, the power lock jumper allows the shaft 34 to go to the upper end of the light 36, which releases

  the energy stored in the spiral spring 32 can also be seen

  this response of the gearbox to the action of the stable two-state mechanism in FIG. 4 where the lower position of the gearbox is illustrated in solid lines and the position shown in lines

mixed purposes.

  FIGS. 5 and 6 illustrate in greater detail the two stable positions of the stable two-state mechanism. One end of the trigger 22 is hooked under a hook 52 near the front end of the frame 24. As seen in FIG. spring in

  Spiral 32 was raised by rolling the vehicle back.

  Therefore, as the vehicle is rolled back, the tension in the spiral spring forces the gearbox 20 to

  swing upwards in the direction of the arrow A

  This is because the rear shoulder 42 of the gearbox 20 pivots against a fulcrum formed by the leg 44 of the frame 24. When the spiral spring 32, Fig. 1, forces the gearbox to switch to the top in the direction of the arrow A, Fig 5, the shaft 34 is held at the lower end of the slot 36 by means of holding the shape of the locking jumper 66 Thus, the pinion 33 places the train of gears in the state corresponding to the movement behind the vehicle, so

to refit the spiral spring.

  To release the energy stored in the spiral spring 32, a downward pressure is exerted on the hood of the car, FIG. The post 64, Fig. 6, is thus pushed downwards in the direction of the arrow B. As the trigger 22 moves down in the direction of the arrow B, its two flanges 70, 72 bear downwardly on the shoulder 46. The gearbox swings in the direction of the arrow C. As the gearbox is in the down position, the top of the locking jumper 66 is above the upper end of the gearbox. the light 36, allowing the pinion on the shaft 34 to move upwards This movement of the pinion moves the gears and allows the gear train in the box 20 to turn in the opposite direction of the direction in which it turns when it is done The reverse movement of the gear train is dependent on the spiral spring 32 In addition, the release of the spiral spring, through the gear train, reduces the force that held the two-state mechanism. stable in the first state

  stable, as seen in Fig 5.

  When the spiral spring unwinds and releases its energy, the stable two-state mechanism remains in the release state of

the energy shown in Fig 6.

  When the vehicle is rolled back again, the energy is stored again in the spiral spring 32 The stable two-state mechanism returns to the locked position of Fig 5 The gear train is still locked by holding from the pinion shaft to the lower end of the lumen 36, until the element 64 is pushed again in the direction of the

arrow B, Fig 7.

  The phases of operation are illustrated in FIGS. 7 and 8.

  In Fig. 7, the vehicle is rolled backwards and the hood is raised. The vehicle can then be left indefinitely. When the child wants the vehicle to start forward, he presses on the hood, Fig 8 This flips the mechanism in two stable states from the position of Fig 5 to the position of Fig 6, and the

  vehicle goes forward under the action of the spiral spring 32.

  The vehicle of the invention has many small advantages

  A toy vehicle that can be controlled without a switch, lever, etc., reinforces the real side of the toy and the play of the child with the toy. In the present invention, for example as shown in FIG. two stable states goes from the position shown in fine dotted lines to the position shown in strong lines

  without the use of switches or levers Alternatively, it is possible to

  It would be necessary to press down on the roof 26 to move the stable two-state mechanism from the position shown in fine dotted lines to the strongly illustrated position. When the stable two-state mechanism moves downwards, a click is heard. , a child can press on the roof until he hears a click to "go back up the car", he can then roll the car back to raise the engine, then press the hood to release the energy This game has a relationship to the real side of life and the

toy vehicle is reliable and safe.

  Tradespeople will quickly realize how

  However, the claims could be modified

  have been planned to cover all equivalent structures

  falling in the real field and in the spirit of the invention.
