Definitions

  • the present invention relates to an instructive toy constituted by a decomposable model of vehicle.
  • toys constituted by models of vehicles capable of being broken down into certain constituent structural parts
  • a toy which represents an internal combustion engine comprising moving parts mounted in a transparent housing which makes it possible to observe the movements.
  • These toys have a certain instructive character as the first highlight the relative position reports of the structural parts of a vehicle and the second highlights, only for the engine, the relationships either structural or functional between its components.
  • instructive toys or didactic means capable of highlighting as a whole either the structure or the operation of all the essential components of a vehicle.
  • the object of the present invention is to produce an instructive toy, or teaching aid, in the form of a decomposable model of vehicle, which in its assembled form allows the observation of the structure and of the simulated coordinated operation of all the functional groups. essential of a real vehicle, and which also allows, in its decomposed form, to observe singularly the structure and the simulated functioning of each functional group considered in itself.
  • the toy comprises a support structure, substantially simulating the chassis of a real vehicle, provided with separable connection means, and number of functional units, each functional unit being provided with separable connection means complementary to the connection means separable from the support structure, and being further provided complementary functional connection means corresponding functional connection means belonging to the other units, each functional unit simulating an essential functional group of a real vehicle, and each functional unit comprising mobile components arranged so as to simulate the functioning of the real functional group simulated, mounted in a transparent case which allows observation.
  • the vehicle model comprises, in its assembled form, units of mobile components, which can be observed through their transparent casings, and which simulate the essential functional groups of a real vehicle, such as the engine. , the change of speed, the differential and the steering mechanism, and therefore it allows the observation either of the relative structural position of these functional groups in a real vehicle, or of their functional relationships coordinated in movement.
  • a general observation is appropriate and useful also for young people whose age is very reduced.
  • the toy used by young people of more mature age, can be broken down into its singular component units, each of which can then be observed separately in detail in its structure and in its functioning, while the operation of breaking down the model in its constituent units and to compose it again constitutes in itself an attractive and formative activity.
  • a particular formative effect can be obtained by subjecting these decomposition and composition operations to defined rules, by providing that the disassembly of the constituent units, as well as their assembly, can be carried out only according to a pre-established order which cannot be waived.
  • each constituent unit in turn, can be made so that it can be dismantled and reassembled again, thus giving greater appeal to the game also for young people whose age is much more mature.
  • the vehicle model includes: a support structure, simulating the chassis of a real vehicle and which for this reason will be referred to as the chassis unit, indicated as a whole by the number 1 and who in this case also includes steering mechanisms and steering knuckles for the application of the front steering wheels; an engine unit, indicated as a whole by the number 2, simulating the internal combustion engine of a real vehicle, applied in a removable manner on the chassis unit 1; a gear change unit, indicated as a whole by the number 3, simulating the gear change of a real vehicle, applied in a removable manner on the chassis unit 1 and operatively connected with the engine unit 2; and a differential unit, indicated as a whole by the number 4, applied in a removable manner on the chassis unit 1, functionally connected with the gear change unit 3 and comprising two half-axles for the application of the rear wheels 6, simulating the drive wheels of a real vehicle.

  • the support structure or chassis unit 1 is shown separately and in more detail in FIGS. 2 and 3. It comprises a box plate, formed by an upper plate 10 and a lower plate 11, which can be connected to one another by elements with elastic release 11 ′, as shown in FIG. 3.
  • the upper plate 10 has surfaces suitable for receiving the motor unit 2, the gear change unit 3 and the differential unit 4, of which only the edges are indicated in these figures.
  • the upper plate 10 is provided with bayonet openings, respectively 12, 13 and 14, for coupling said units, the fixing of which will be described later.
  • the chassis unit 1 comprises vertical bearings 15 in which are housed the pivot pins 16 ′ of the stub axles 16 provided for mounting the front steering wheels 5, the attachment of which to the stub axles will be described later. .
  • the chassis unit also includes an inclined support 17 for a steering control 18, coupled by means of an eccentric 18 'to a transverse bar 19 articulated to the rocket carriers 16, so that the operation of the steering control 18 makes it possible to orient ( within certain limits indicated by broken lines in FIG. 2) the stub axles 16 and therefore the front steering wheels 5.
  • the engine unit 2 shown separately and in more detail in FIGS. 4 to 7, comprises a base plate 20 on which is mounted a housing 22 simulating the monoblock and the head of an internal combustion engine.
  • the housing 22 is made of a transparent material to allow the observation of the structure, relationships and movements of the internal parts.
  • the connection between the base 20 and the housing 22 can be made by means of elastic triggering elements 20 ′, as shown in FIG. 7.
  • the base 20 has bayonet projections 21 capable of engaging the bayonet openings 12 of the chassis unit 1.
  • the motor unit 2 can be mounted on the chassis unit 1 by engaging the projections 21 in the openings 12 and then sliding the motor unit 2 backwards. The mounting position can then be stabilized by means of the arrangement shown in FIG. 7.
  • a lever 7 is pivoted in the chassis unit 1 and comprises at one of its ends a pusher 8 which makes it possible to lower the lever 7 against the action of an elastic appendage 7A of the lever 7.
  • the lever 7 further comprises a tooth 9 capable of being inserted in the widest part of a bayonet opening 12.
  • the transparent housing 22 includes bench supports 22 'in which a bent shaft 23 is pivoted provided with crank pins 23'. On each crank pin 23 'is pivoted a connecting rod 24 articulated to a piston 25 slidably mounted in a partially cylindrical guide part of the housing 22. On the front end of the bent shaft 23 is mounted a flywheel 26 provided with a flap 27; these parts stand out better in FIG. 1. Similarly, on the rear end of the bent shaft 23 is mounted a flywheel 28 provided with a splash 29, intended to give rise to the functional connection of the unit motor 2 with gear change unit 3.
  • the shift unit 3 shown separately and in more detail in Figures 8 to 10, comprises a base plate 30 on which is mounted a housing 32 simulating the gear change housing of a motor vehicle.
  • the housing 32 is made of a transparent material to allow the observation of the structure, relationships and movements, of the internal parts.
  • the connection between the base 30 and the housing 32 can be made by means of elastic triggering elements 30 ′, as shown in FIG. 10.

  • the shift unit 3 can be mounted on the chassis unit 1 by engaging the projections 31 in the openings 13 and then sliding the shift unit 3 backwards. The mounting position can then be stabilized by means of the arrangement shown in FIG.
  • the transparent housing 32 has two fixed bearings 32 'and 32'', and in its interior are mounted two oscillating bearings 33' and 33 '', which can be moved in the horizontal direction by means of a cam 34 'secured to an operating handle 34 disposed outside the housing 32 and which can be operated by rotating it.
  • a motor shaft 35 which carries two cogwheels 35 'and 35''and, at its front end, a flywheel 37 provided with a splash 37' complementary to the splash 29 of the flywheel 28 of the motor unit 2.
  • a driven shaft 36 which carries two toothed wheels 36 'and 36'', arranged opposite the wheels 35' and respectively 35 '' of the motor shaft 35.
  • a flywheel 38 provided with a chuck 39 is mounted on the rear end of the driven shaft 36.
  • the shafts 35 and 36 can take different relative positions in a horizontal plane.
  • the shaft 35 is parallel to the longitudinal axis of the housing 32, while the shaft 36 is inclined; the gear wheels 35 '' and 36 '' mesh with each other, while the gear wheels 35 'and 36' are at a certain reciprocal distance and do not mesh.
  • the gear wheels 35 'and 36' are at a certain reciprocal distance and do not mesh.
  • the shafts 35 and 36 are both inclined relative to the longitudinal axis of the housing 32, and neither the gears 35 'and 36', nor the gears 35 '' and 36 '' mesh with each other.
  • the speed change unit 3 therefore forms a variator of the transmission ratio between the flywheels 37 and 38, with two different transmission reports and a mad condition.
  • the differential unit shown separately and in more detail in Figures 11 to 14, comprises a base plate 40 on which is mounted a housing 42 simulating the rear axle of a motor vehicle.
  • the housing 42 is made of a transparent material to allow the observation of the structure, relationships and movements of the internal parts.
  • the connection between the base 40 and the housing 42 can be made by means of elastic trigger elements 40 ', as shown in FIG. 14.
  • the base 40 has bayonet projections 41 capable of engaging the bayonet openings 42 of the chassis unit 1.
  • the differential unit 4 can be mounted on the chassis unit 1 by engaging the projections 41 in the openings 14 and then sliding the differential unit 4 laterally (downwards according to FIG. 2).
  • the mounting position can then be stabilized by means of the arrangement shown in Figure 14, comprising a lever 7 '' with an elastic appendage 7A '', a pusher 8 '' and a tooth 9 ''.
  • This arrangement 7 '' - 9 '' is very similar, in its structure and in its function, to arrangement 7-9 described in connection with the motor unit 2 with reference to FIG. 7, and therefore it will not be not described later.
  • the housing 42 retains in the correct position elements 43 which form several bearings arranged as shown in FIGS. 11 and 12.
  • two coaxial half-axles 44 each of which carries at its internal end a toothed wheel bevel 44 'and at its outer end a spindle 44''for mounting one of the rear wheels 6 (shown, with the differential unit, in Figure 11).
  • the cage 45 is mounted on the internal ends of the coaxial shafts 44, so that it can rotate, and it carries an external conical toothed crown 45 ''.
  • the 44-45 mechanism now described forms a differential mechanical between the toothed ring gear 45 '' and the half-axles 55, driven by it in a differential manner.
  • the toothed crown 45 '' in turn meshes with a conical gear 46 'carried by the inner end of a shaft 46 mounted in a pair of coaxial bearings 43 of the housing 42.
  • a flywheel 47 provided with a flap 48, which is complementary to the flap 39 of the rear flywheel 38 of the speed change unit 3. It can be noted that all the flywheels described: 26, 28, 37, 38 and 47, can be identical between them in their construction.
  • Each rear wheel 6 has a hub 60 by means of which the wheel can be mounted on the spindle 44 '' of one of the half-axles 44 of the differential unit 4, and the wheel is shaped so as to engage, when it is mounted, with a tooth 49 of the half-axle 44, so as to be integral in rotation relative to the half-axle on which it is mounted.
  • at least one elastic lock 61 (Figure 11), and in practice there are preferably two diametrically opposite locks ( Figure 1).
  • the lock 61 is arranged so as to elastically relax in a groove in the respective half-axle 44, in order to retain the wheel in the mounting position.
  • the lock 61 nevertheless allows the disassembly of the wheel, which can be carried out by pulling the locks 61 outwards and releasing the wheel from the rocket which supports it.
  • each front wheel 5 has a hub 50 by means of which the wheel can be mounted on the stub axle 16 of the chassis unit 1.
  • the stub axle 16 is not provided with a similar tooth of the tooth 49 of the half-axle 44, so that the front wheel 5 is free to rotate on the stub axle 16 supporting it.
  • At least one latch 51 retains the wheel 5 in the correct position on the stub axle, without preventing rotation, and allows it to be dismantled.
  • the arrangement, identical to the arrangement 60-61 described for the rear wheels 6, is not described later and results only from FIG. 1. It is noted that the front wheels 5 and the rear wheels 6 can be identical from the construction point of view.
  • each of these units can be examined singularly in its structure, revealed by the transparent case, and, by turning one of the steering wheels with which each unit is provided, one can examine in detail the functional relationships between the interior components.
  • the motor unit 2 we can understand the relationship between the rotary movement of the bent shaft 23 and the alternative movements of the connecting rods 24 and the pistons 25.
  • the gear change unit 3 we can observe as the transmission is established or interrupted and the transmission ratio is changed. From the observation of the differential unit one can clarify the functioning of a mechanical differential, which is complicated in itself and could not be easily understood by intuition.
  • the disassembly of the different functional units is carried out, in the preferred embodiment described, by releasing each unit by the pressure of a pusher which can be accessed from the upper part e by the simultaneous movement of the unit in a pre-established direction.
  • the use, as a control member of the release, of a pusher which is controlled from the upper part, makes this operation considerably easy.
  • the operation of mounting the different functional units on the chassis unit is in itself a pleasant and formative activity. After that it was carried out by arranging the different units in the order and in the established manner, fixing them in their positions, and taking care to functionally couple the chopper 29 of the motor unit 2 with the chopper 37 ' of the gearshift unit 3 and the chopper 39 of the gearshift unit 3 with the chuck 48 of the differential unit 4, it is possible to observe as a whole the functional relationships of the mechanisms, from the motor to at the vehicle wheels, in the different positions of the gear change. Because this observation does not require any manual skill, it is also accessible to young people of very reduced age, who would not yet be able to carry out the dismantling and mounting operations of the functional units, operations suitable for young people in the older age.
  • the various constituent units are assembled, in turn, by the use of elements with elastic release such as 11 ', 20', 30 ', 40'. So, by releasing these elements, it is possible to disassemble each unit in its individual component elements, and then mount it again.
  • Such an operation is much more engaging than the operations concerning the decomposition and the composition of the model, described previously.
  • Such an operation can be carried out only by young people whose age is already considerably ripe, and it extends to these young people the attraction of the game, by increasing it.
  • the model under consideration which refers to an automobile having a front engine, rear traction and front steering wheels
  • the model under consideration can be modified with respect to a rear arrangement of the engine, to an anterior position of the drive wheels, to all-wheel drive on the four wheels, or even a steering character of all four wheels, as it is made in certain special vehicles.
  • the power unit which was shown by example with three cylinders in line, could have any number of cylinders, arranged in line in a vertical or horizontal plane, or else arranged in V or in star.
  • the gearshift unit could comprise more than two transmission ratios, and these different ratios could be obtained in a different way from that shown, if necessary in a more faithful way compared to reality, and this is by means of radial meshes, either by front chocks.
  • the differential unit could include mechanisms for locking the differential, as provided in all-terrain vehicles.
  • the rear axle could include two axles and / or twin wheels, as used on trucks.
  • the steering control unit which in the example is part of the chassis unit, could constitute a removable functional unit.
  • the functional coupling among the different units could be carried out in a different way from that comprising flywheels with flaps.
  • the mounting and the releasable fixing of the functional units on the chassis unit could be carried out in any way different from that described.
