Description

Dispositivo de regulación en altura para el eje de un coche de juguete.Height adjustment device for the shaft of a toy car.

Object of the invention

La presente invención se refiere a un dispositivo para el montaje del eje o los ejes de un coche de juguete, que permite la regulación en altura del mismo con respecto al chasis que lo soporta, en orden a adaptarlo a diferentes diámetros de rueda o a cualquier otro tipo de condicionante.The present invention relates to a device for mounting the axle or axles of a toy car, which it allows the height adjustment of the same with respect to the chassis that supports it, in order to adapt it to different diameters of wheel or any other type of conditioner.

El objeto de la invención es conseguir un perfecto ajuste, en continuo, de la citada altura del eje, dentro de dos límites preestablecidos y separados por una notable amplitud.The object of the invention is to achieve a perfect adjustment, continuously, of the aforementioned shaft height, inside of two preset limits and separated by a remarkable amplitude.

La invención resulta de especial aplicación en los coches de juguete accionados por un micro-motor eléctrico tipo de los que circulan sobre superficies de guías ranuradas.The invention is of special application in toy cars powered by a micro-engine Electric type of those circulating on guide surfaces grooved

Background of the invention

Como es sabido, los coches de juguete del tipo anteriormente citado, están provistos de un chasis inferior, generalmente de plástico, aunque también puede ser metálico, sobre el que se montan dos ejes transversales, uno anterior y otro posterior, dotados de respectivas parejas de ruedas, de los que uno de ellos, o en tracción "4x4" los dos, es el eje motriz, conectado mediante una transmisión apropiada al micro-motor eléctrico, mientras que el otro gira libremente.As is known, toy cars of the type previously mentioned, they are provided with a lower chassis, generally of plastic, although it can also be metallic, about which are mounted two transverse axes, one anterior and the other later, equipped with respective pairs of wheels, of which one of them, or in traction "4x4" the two, is the driving axle, connected by an appropriate transmission to electric micro-motor while the other rotates freely.

Este tipo de coches de juguete alcanzan notables velocidades, toman la corriente de la propia pista a través de escobillas, generalmente tiene la tracción en el eje trasero, y deben desplazarse en situación de máxima proximidad a la pista, para que sea mayor su estabilidad.This type of toy cars reach remarkable speeds, take the current from the track itself through brushes, usually has traction on the rear axle, and must move in a situation of maximum proximity to the track, so that its stability is greater.

Aunque el eje no motriz puede girar loco, como anteriormente se ha dicho, generalmente esta montado con carácter fijo sobre el chasis, de manera que son las ruedas las que giran libremente sobre los extremos del mismo. Existen diferentes soluciones para montar el citado eje no motriz sobre el chasis, pero todas ellas presentan como denominador común el hecho de que dicho eje tiene una posición predeterminada e invariable en altura, de manera que el distanciamiento del coche con respecto a la pista es también invariable, en función del diámetro de las ruedas.Although the non-drive axle can go crazy, like previously said, it is usually mounted with character fixed on the chassis, so that it is the wheels that rotate freely on the ends of it. There are different solutions for mounting said non-drive axle on the chassis, but all of them present as common denominator the fact that said axis has a predetermined position and invariable in height, so that the distance of the car from the track It is also invariable, depending on the diameter of the wheels.

Si por cualquier motivo se pretende la sustitución de las ruedas originales por ruedas de diferente diámetro, esto trae consigo una elevación o un descenso del chasis, lo que no es factible o deseable, ya que una elevación del chasis hace que el vehículo pierda estabilidad, y un descenso del mismo puede originar el contacto del chasis con la pista, lo que en la practica equivale a una imposibilidad en el citado cambio de ruedas, o a que dicho cambio traiga consigo problemas funcionales del coche.If for any reason the replacement of the original wheels with wheels of different diameter, this brings with it an elevation or a descent of the chassis, which is not feasible or desirable, since a chassis lift causes the vehicle to lose stability, and a decrease in it it can cause chassis contact with the track, which in the practice amounts to an impossibility in the aforementioned change of wheels, or to that change brings with it functional problems of the car.

Description of the invention

El dispositivo de regulación que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, permitiendo que el chasis mantenga su distanciamiento óptimo con respecto a la pista, a pesar de que se utilicen ruedas de diferentes diámetros.The regulating device that the invention proposes to solve the problem fully satisfactorily previously exposed, allowing the chassis to maintain its optimal distance from the track, despite the fact that use wheels of different diameters.

Para ello y de forma más concreta dicho dispositivo, en correspondencia con cada uno de los extremos del eje, incorpora dos topes contrapuestos y regulables en altura, que atacan respectivamente a las generatrices superior e inferior del eje, materializados en sendos tornillos prisioneros, preferentemente tipo "allen", destinados a presionar simultáneamente sobre el eje, pero que en función del posicionamiento de cada uno de ellos sobre el correspondiente orificio roscado permiten que dicho eje ascienda o descienda con respecto al chasis, dentro de amplios márgenes.To do this and more specifically said device, in correspondence with each of the ends of the shaft, incorporates two opposing stops and adjustable in height, which respectively attack the upper and lower generatrices of the shaft, materialized in two captive screws, preferably type "allen", intended to press simultaneously on the axis, but depending on the positioning of each of them on the corresponding threaded hole allow said shaft to ascend or descend with with respect to the chassis, within wide margins.

De forma más concreta el tope inferior está situado sobre una protuberancia del chasis, mientras que el tope superior está establecido sobre la rama media en una especie de puente en "U" de dimensiones adecuadas para alojar entre sus ramas laterales al eje y que lógicamente permite un amplio desplazamiento de dicho eje paralelamente a dichas ramas, es decir en sentido vertical.More specifically, the bottom stop is located on a protrusion of the chassis, while the stop upper is established on the middle branch in a kind of U-shaped bridge of adequate dimensions to accommodate between its lateral branches to the axis and that logically allows a wide displacement of said axis parallel to said branches, ie vertically

Una pareja de estos topes, por ejemplo los inferiores, determinan por su propio posicionamiento el nivel en altura del eje con respecto al chasis, mientras que los otros dos actúan como prisioneros que inmovilizan dicho eje en sentido vertical.A pair of these stops, for example the lower, determine the level in their own positioning shaft height with respect to the chassis, while the other two they act as prisoners that immobilize said axis in the sense vertical.

Aunque la invención está fundamentalmente destinada al eje no motriz del coche de juguete, evidentemente puede ser aplicada igualmente al eje motriz, sin más que intercalar entre el eje y los topes casquillos o cojinetes que permitan el libre y necesario giro del repetidamente citado eje.Although the invention is fundamentally intended for the non-driving axle of the toy car, obviously It can also be applied to the drive axle, without interposing between the shaft and the bushing or bearing stops that allow the free and necessary rotation of the aforementioned axis.

Preferred Embodiment of the Invention

En las figuras reseñadas se ha referenciado con (1) el chasis del coche, sobre el que aparece montado el eje delantero (2) correspondiente a las ruedas (3) no motrices, siendo evidente que la configuración de este chasis (1) obedece a un mero ejemplo de realización práctica que puede variar ampliamente, sin prácticamente limitación alguna al respecto, excepto en lo que se refiere al dispositivo de la invención.In the figures outlined it has been referenced with (1) the car chassis, on which the axle appears mounted front (2) corresponding to non-driving wheels (3), being Obviously the configuration of this chassis (1) is due to a mere practical embodiment example that can vary widely without practically any limitation in this regard, except as far as refers to the device of the invention.

Pues bien, dicho dispositivo se materializa, en correspondencia con la zona próxima a cada uno de los extremos del citado eje (2), en una protuberancia (4) que emerge ascendentemente del chasis (1) y que está afectada por un orificio vertical (5), con un sector roscado (6), en el 5 que juega un tornillo (7), preferentemente tipo "allen", accionable con la correspondiente llave desde la cara inferior del chasis y a través del citado orificio (5), constituyendo dicho tornillo (7) un tope de posicionamiento en altura regulable para el eje (2), como se observa especialmente en la figura (3).Well, this device materializes, in correspondence with the area near each end of the cited axis (2), in a protuberance (4) that emerges ascendingly of the chassis (1) and which is affected by a vertical hole (5), with a threaded sector (6), in which 5 plays a screw (7), preferably type "allen", operable with the corresponding key from the underside of the chassis and through of said hole (5), said screw (7) constituting a stop adjustable height positioning for the shaft (2), as observe especially in figure (3).

En las proximidades de la protuberancia (4) se establece una especie de puente (8), de configuración en "U" invertida, y cuyas ramas laterales (9) emergen también ascendentemente del chasis (1), para que su rama media, que se corresponde con la propia referencia (8), quede situada sustancialmente por encima del eje (2), contando dicha rama media (8) con un orificio roscado (10) para acoplamiento de un segundo tornillo (11), también preferentemente tipo "allen", que constituye el segundo tope, contrapuesto al tope (7) anteriormente citado, de manera que dichos topes son susceptibles de ascender y descender con respecto al chasis (1) y, consecuentemente, de fijar al eje (2) en diversas posiciones en altura que se extienden desde la extremidad superior de la protuberancia (4) a la cara inferior de la rama media del puente (8).In the vicinity of the bump (4) it set a kind of bridge (8), set to "U" inverted, and whose lateral branches (9) also emerge ascending the chassis (1), so that its middle branch, which corresponds to the reference itself (8), is located substantially above the axis (2), said middle branch counting (8) with a threaded hole (10) for coupling a second screw (11), also preferably "Allen" type, which constitutes the second stop, as opposed to the stop (7) above cited, so that these stops are likely to rise and descend with respect to the chassis (1) and, consequently, to fix to the axis (2) in various positions in height that extend from the upper extremity of the bulge (4) to the lower face of the middle branch of the bridge (8).

De esta manera a medida que los topes (7) descienden desciende también el eje (2) y viceversa, quedando en cualquier caso dicho eje debidamente fijado en la posición elegida mediante el apriete de los tornillos superiores (11).In this way as the stops (7) descend also descend the axis (2) and vice versa, remaining in in any case, said axis properly fixed in the chosen position by tightening the upper screws (11).

Evidentemente y como ya se ha dicho con anterioridad, el dispositivo de regulación es aplicable también al eje motriz del coche, no representado en los dibujos, sin más que establecer entre el eje (2) y los torpes (7) y (11) casquillos o cojinetes que permitan el libre giro de dicho eje.Obviously and as already said with previously, the regulation device is also applicable to drive axle of the car, not represented in the drawings, without more than establish between the shaft (2) and the clumsy (7) and (11) bushings or bearings that allow free rotation of said shaft.
