Definitions

  • the invention relates to a method of assembling one or more multiple wheels on a miniature vehicle and on a vehicle miniature.
  • wheels belonging to the same set of wheels are linked together, in rotation and in translation, by an axis, that is to say that the wheels on the same axle rotate at the same time.
  • This link in rotation and translation affects the capacity of these vehicles thumbnails to take turns and can make you lose the child's interest in play.
  • Some model cars have independent wheels rotating on the same axis In this case, these wheels are mounted by means of systems complex on the chassis or body of the vehicle, which increases the production cost thereof accordingly and causes most often a fragile character which is incompatible with the use of the vehicle as a toy by a young person child, in particular by a child under 36 months.
  • US-A-5,380,231 aims to provide a miniature vehicle in which the wheel lock is unstable to the point that the vehicle spontaneously disassembles during an impact.
  • the hanging temporary wheels on the chassis is made without rider but by means of a complex device comprising levers controlled by springs.
  • the invention aims to solve these problems and to propose a method of assembling one or more wheels on a vehicle miniature allowing effective attachment of the wheel or wheels relative to the rest of the vehicle and free rotation of one wheel relative to the other wheel of the same wheel set.
  • the invention relates to an assembly method one or more wheels on a miniature vehicle comprising a chassis and a body which consists of drive the end of a wheel hub through a rider secured to the chassis or body and to keep this hub in the depressed position in the rider.
  • This method further comprises partially accommodating an axis with inside the hub of a first wheel, before driving in the end of this hub through the jumper and to cap a free end of this axle with a hub of a second wheel intended to be mounted opposite the first wheel in pushing the end of the second hub through a second rider secured to the chassis or body.
  • the axis which can be metallic, is thus trapped between the two hubs of two wheels of the same wheel set, which gives good rigidity to the whole as well formed, this axis serving as an axle for this set of wheels.
  • the invention also relates to miniature vehicles. each comprising a chassis, a body and a plurality wheels each secured to a hub carrying a flange external.
  • a vehicle comprises at least one rider formed by two deformable lugs formed integrally with the chassis or the body.
  • such a vehicle comprises at least one rider formed from a drilled block a circular hole centered on the axis of the hub. Whatever either the embodiment considered, the rider is able to cooperate with the flange of each hub to immobilize it in translation in a tearing direction relative to the chassis or bodywork.
  • the vehicle 1 in FIG. 1 essentially comprises a chassis 2 and a bodywork 3 mounted on the chassis by any means suitable for those skilled in the art.
  • Four wheels are distributed between a front axle, formed by two front wheels whose axes of rotation are aligned, and a rear axle, formed by two rear wheels whose axes of rotation are also aligned.
  • Each wheel comprises a hub 4 has come integrally with it and capable of supporting the latter.
  • each hub 4 a carries an external collar 4 b , that is to say extending radially relative to the axis of the hub 4 a .
  • Jumpers 5 are formed on the upper surface of the chassis 2 by two lugs 5 a and 5 b formed integrally with the chassis and separated by a space 5 c whose width is slightly less than the diameter of the collar 4 b .
  • the chassis 2 also comprises four holes 6, two of which are visible in FIG. 1, through which the hub 4 a of each wheel 4 can be inserted in the direction of the corresponding jumper 5.
  • the end of the hub 4 a that constitutes the flange 4 b is introduced through the jumper 5.
  • the end of the hub 4 a carries a chamfer 4 c which constitutes the front face of the flange 4 b .
  • the axial force exerted by the fitter on the wheel 4 is therefore transformed, by virtue of the chamfer 4 c , into a radial and axial force which makes it possible to separate the lugs 5 a and 5 b by using their deformable nature.
  • the rear face 4 d of the flange 4 b facing the wheel 4 is substantially radial, so that, when the flange 4 b has passed the pins 5 a and 5 b , the rear face 4 d constitutes a face d 'radial support of the collar 4 b on the pins 5 a and 5 b .
  • the pins 5 a and 5 b these are much more difficult to deform in a direction parallel to the axis XX 'common to the hubs of the two wheels of the rear axle, so that they do not deform when a tear-off force is exerted on the wheel 4.
  • the flange 4 b and the rider 5 are able to immobilize the hub 4 a in translation in a tear-off direction of the wheel 4 relative to the chassis 2.
  • the end of the hub 4 a formed by the flange 4 b is introduced through the jumper 5 and the hub 4 a is kept in the depressed position in the jumper 5 thanks to the geometry of the collar 4 b .
  • the hub 4a has two shoulders 4 e and 4 f intended to rest respectively against the edge of the lugs 5 a and 5 b and against the edge of the orifice 6, when the end of the hub 4 a is introduced beyond the jumper 5 with respect to the orifice 6.
  • These two shoulders 4 e and 4 f serve to immobilize the hub 4 a in translation in the driving direction of the hub 4 a through the orifice 6. In other words, their function is to prevent the wheel 4 from being pushed too deeply into the orifice 6 or into the jumper 5.
  • the vehicle of the embodiment of FIGS. 1 to 4 also comprises an axis 7, for example metallic, partially inserted inside a central orifice 4 g of the hub 4 has wheels 4
  • this axle constitutes an axle which gives good mechanical stability to the train of wheels thus formed.
  • it avoids any pivoting of the hub 4 perpendicularly to the axis XX 'in a direction which would tend to remove the end 4b of the hub 4a of the upper surface of the chassis 2.
  • the mounting method is as follows: the axle 7 is partially housed inside the hub 4 a of a wheel, shown on the right in FIG. 2, then the hub 4 a is introduced through the orifice 6 and its end 4 b through the jumper 5. The free end 7 a of the axis 7 then protrudes from the hub 4 a of the right wheel in the direction of the orifice 6 located on the left of FIG. 2. In this position , the end 7 a is capped with the hub 4 a of the left wheel by introducing the end of this second hub through a second jumper 5 secured to the chassis 2, located on the left of FIG. 2.
  • the assembly carried out which appears in Figure 3, is solid and allows good attachment of the wheels 4 on the chassis 2.
  • the outside diameter of the axis 7 may be smaller than the diameter of the central orifices 4 g of the hubs wheels 4a, so that the wheels 4 are free to rotate relative to the shaft 7, which allows a differential speed of the wheels on the left and right of the model vehicle when it follows a curved path.
  • FIGS 5 and 6 show a second embodiment of the invention, in which the constituent elements similar to those of the embodiment of Figures 1 to 4 bear identical references increased by 50.
  • This embodiment differs from the previous in that it is not intended axis connecting the hub 54 has two wheels 54 belonging to the same wheel set of the vehicle 51.
  • each hub 54 a includes an outer flange 54 b whose front face is formed by a chamfer 54 c facilitating its introduction through a jumper 55.
  • Each jumper 55 consists of two deformable lugs 55 a and 55 b made integrally with the chassis 52.
  • Each hub 54 a includes, as before, a rear flange face 54 d substantially radial and two shoulders 54 e and 54 f capable of immobilizing, in the direction of driving in, the wheel 54 relative to an orifice 56 in the chassis 52 and to the rider 55.
  • the collar 54 b cooperates with the rider 55 to immobilize the hub 54 a in translation in the direction of tearing.
  • the pins 55 a and 55 b each have one end, respectively 55 a 1 and 55 b 1, undercut relative to the space 55 c formed between the two pins 55 a and 55 b , so that when the hub 54 a is engaged in the space 55 c , it and retained upwards by the ends 55 a 1 and 55 b 1. This makes it possible to avoid the pivoting movements of the wheels 54 relative to a horizontal axis perpendicular to the axis XX '.
  • the vehicle body includes a stop which, when the body is mounted on the chassis 52, is capable of coming to bear against the upper face of the hub 54 a .
  • This stop also has the function of avoiding the previously mentioned pivoting of the hub 54 a .
  • the undercut ends 55 a 1 and 55 b 1 can optionally be removed.
  • FIGS. 7 and 8 represent a third embodiment of the invention in which the elements similar to those of the embodiment of FIGS. 1 to 4 bear identical references increased by 100.
  • This embodiment differs from the previous ones essentially in that the jumpers 105 are carried by the body 103 of the vehicle 101.
  • This body comprises a veil 103 a extending transversely over a frame 102.
  • Each jumper 105 is formed from a block made of material with the veil 103 a pierced with a circular opening 105 centered on the axis XX 'of the hubs 104 has wheels 104 of the respective wheelset.
  • Each hub 104 comprises at its end a flange 104 b whose external shape is substantially identical to that of the flanges 4 b and 54 b of the preceding embodiments.
  • the hub 104 a carries a chamfer 104 c , a radial rear face 104 d and two shoulders 104 e and 104 f .
  • This flange is able to cooperate with the rider 105 to immobilize the hub 104 a in the direction of the pullout parallel to the axis XX 'thanks to the rear face 104 d of the flange 104 b .
  • the hub 104 a carries shoulders 104 e and 104 f opposing the driving of the wheel 104 into the body 103 insofar as the shoulder 104 e abuts against the rider 105 and / or the shoulder 104 f abuts against the edge of an orifice 106 provided, for example in the bodywork 103.
  • the orifice 106 is circular and centered on the axis XX 'of the hubs 104 a .
  • the hub 104 a is formed from a plurality of flexible strips 104 g which appear more particularly, four in number, in FIG. 8. Thanks to their flexibility properties, these strips can deform to allow the passage of the flange 104 b in the orifice 105 a .
  • the hubs 54 a and 104 a of the second and third embodiments are, like the hub 4 a of the first embodiment, made integrally with the wheel to which they belong.
  • the hub is constituted by a separate part from the wheel and force-fitted into an axial orifice of the latter.
  • the hub and the wheel constitute a unitary assembly which is not likely to be dismantled by a child playing with the miniature vehicle of the invention.
  • the hubs 54 a and 104 a are provided with a central orifice for receiving part of an axle forming an axle of a train of two wheels.
