Description

TAPACUBOS PARA RUEDAS DE VEHÍCULOS OBJETO DE LA INVENCIÓN COVERS FOR VEHICLE WHEELS OBJECT OF THE INVENTION
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a tapacubos para ruedas de vehículos, el cual está dotado en su reverso o cara posterior de unas proyecciones tubulares situadas de manera tal que, en su montaje sobre la correspondiente llanta de la rueda, se corresponden con los tornillos de fijación de ésta. Las proyecciones tubulares cuentan con una serie de lengüetas flexibles labiadas y forzadas por un elemento elástico de compresión, como puede ser un aro metálico, determinando en conjunto un medio de retención y enclavamiento del tapacubos, cuyo desmontaje requiere la extracción previa de los tornillos de fijación de la rueda.The present invention, as expressed in the statement of this specification, refers to hubcaps for vehicle wheels, which is provided on its back or rear face with tubular projections located in such a way that, when mounted on the corresponding wheel rim, correspond to the bolts fixing it. The tubular projections have a series of flexible tongues carved and forced by an elastic compression element, such as a metal ring, jointly determining a means of retention and interlocking of the hubcaps, whose disassembly requires the prior extraction of the fixing screws of the wheel.
El objeto de la invención es proporcionar una pieza adicional aplicable al tipo de tapacubos referido, para conseguir un mejor centrado en el montaje, así como para mejorar la apariencia estética del tapacubos, ocultando las ranuras determinadas entre las lengüetas correspondientes a las proyecciones tubulares en las que precisamente se acopla ajustadamente la pieza adicional.The object of the invention is to provide an additional part applicable to the type of hubcap referred to, in order to achieve a better focus on the assembly, as well as to improve the aesthetic appearance of the hubcap, hiding the grooves determined between the tabs corresponding to the tubular projections in the that precisely fits the additional piece.
ANTECEDENTES DE LA INVENCIÓN En la Patente de Invención n° P-200102699, se describe un tapacubos que está constituido de tal manera que supone una solución sencilla y eficaz a determinados problemas e inconvenientes de las distintas formas de sujetarse un tapacubos a la correspondiente rueda del vehículo, para ocultar y proteger la parte externa de la llanta y el correspondiente buje en que monta la rueda.BACKGROUND OF THE INVENTION In the Invention Patent No. P-200102699, a hubcap is described that is constituted in such a way that it supposes a simple and effective solution to certain problems and inconveniences of the different ways of attaching a hubcap to the corresponding wheel of the vehicle, to hide and protect the outer part of the tire and the corresponding hub on which the wheel is mounted.
Concretamente, el tapacubos descrito en dicha Patente de Invención, presenta en su cara posterior una serie de proyecciones tubulares que se corresponden en posición con la ubicación de los tornillos de sujeción de la llanta, teniendo cada proyección una serie de lengüetas flexibles mediante las que se consigue la fijación a la cabeza del correspondiente tornillo.Specifically, the hubcap described in said Invention Patent, presents on its rear face a series of tubular projections that correspond in position with the location of the fastening screws of the rim, each projection having a series of flexible tabs by means of which the fixation to the head of the corresponding screw is achieved.
Cada lengüeta presenta un labio interior con su frente inclinado de forma divergente hacia el borde externo, determinando un medio que permite el deslizamiento respecto de la cabeza del tornillo, hasta sobrepasar un resalte anular de éste, tras el cual se produce un enclavamiento por medio de un escalón con que al efecto cuenta la parte interna o posterior del labio. Los labios de las distintas lengüetas forman una virtual corona de retención, estando aquéllas ligeramente comprimidas conjuntamente mediante un elemento elástico, tal como un fleje o aro metálico de compresión.Each tongue has an inner lip with its front inclined divergently towards the outer edge, determining a means that allows sliding with respect to the head of the screw, until it exceeds an annular projection of the screw, after which an interlocking occurs by means of a step with which the internal or posterior part of the lip counts. The lips of the different tongues form a virtual retention crown, which are slightly compressed together by an elastic element, such as a strap or compression metal ring.
En dicha corona de lengüetas van intercaladas, al menos, dos lengüetas rígidas dispuestas en oposición diametral, en las que la parte interna de las mismas es lisa, es decir, carente del labio, estando externamente rigidizadas por un nervio radial que discurre perpendicularmente a la respectiva lengüeta fija. De esta manera, el montaje del tapacubos sobre la llanta de la rueda, una vez fijada ésta al buje mediante los tornillos, se efectuará enfrentando las proyecciones tubulares con los tornillos y realizando seguidamente una presión o empuje del tapacubos con el consiguiente deslizamiento de las cabezas del tornillo respecto de las proyecciones tubulares, hasta que el escalón posterior del labio de las lengüetas sobrepase el resalte anular de las cabezas de los tornillos, en cuyo momento y debido al aro elástico de compresión las lengüetas tienden a converger y se produce el enclavamiento entre el escalón del labio y el resalte de la cabeza del tornillo.In said crown of tongues, at least two rigid tongues arranged in diametral opposition are intercalated, in which the internal part thereof is smooth, that is, devoid of the lip, being externally stiffened by a radial nerve that runs perpendicular to the respective fixed tab. In this way, the assembly of the hubcap on the wheel of the wheel, once it is fixed to the hub by means of the screws, will be carried out facing the tubular projections with the screws and then performing a pressure or thrust of the hubcap with the consequent sliding of the heads of the screw with respect to the tubular projections, until the posterior step of the tongue of the tongues exceeds the annular projection of the screw heads, at which time and due to the elastic compression ring the tongues tend to converge and the interlocking occurs between the step of the lip and the head of the screw head.
Una vez montado el tapacubos se hace necesario extraer los tornillos para conseguir su desmontaje, evitando con ello la pérdida, robo, etc. DESCRIPCIÓN DE LA INVENCIÓN Basándose en el tapacubos descrito en el apartado anterior, se han previsto unas mejoras consistentes en la incorporación de una pieza adicional prevista para conseguir un centraje en el montaje y fijación del tapacubos, así como una mejor apariencia de éste.Once the hubcap is assembled, it is necessary to remove the screws to achieve their disassembly, thereby avoiding loss, theft, etc. DESCRIPTION OF THE INVENTION Based on the hubcap described in the previous section, there are planned improvements consisting of the incorporation of an additional piece intended to achieve a centering in the assembly and fixing of the hubcaps, as well as a better appearance of it.
Dicha pieza adicional está constituida por un casquillo cilindrico que se monta a presión en cada proyección tubular del tapacubos, quedando retenida en éste mediante unos resaltes laterales de dicha pieza adicional que se enclavan en respectivas escotaduras previstas al efecto en la proyección tubular, contando la propia pieza adicional en su embocadura externa con un reborde que se posiciona y hace tope en un pequeño escalón de las lengüetas flexibles. La pieza adicional en cuestión presenta, en correspondencia con su superficie lateral y en el sentido de una de las generatrices, un resalte que se ubica en una ranura de la proyección tubular, determinando una única posición de montaje para dicha pieza, la cual está prevista para su aplicación en proyecciones tubulares en las que todas sus lengüetas sean flexibles, aunque también es posible su aplicación en aquellas proyecciones tubulares que cuenten con lengüetas flexibles entre las que van intercaladas lengüetas fijas. En cualquier caso, la comentada pieza adicional cuenta en el borde de su embocadura interna con unas patillas flexibles que discurren entre las lengüetas de la proyección tubular, y sobre cuyas patillas flexibles ajusta el diámetro correspondiente al resalte de mayor diámetro con que está dotada la cabeza del tornillo, haciendo la función de centrado y colaborando dichas patillas en el posicionado y sujeción del aro metálico que como elemento elástico mantiene la tensión de las lengüetas flexibles de la proyección tubular, impidiendo que se puedan desplazar de su alojamiento o posición. La comentada pieza adicional tendrá una longitud superior a las ranuras de las lengüetas flexibles, consiguiendo que éstas queden siempre cubiertas, lo que mejora el aspecto del tapacubos, cumpliendo así eficazmente su función de embellecedor de la rueda.Said additional piece is constituted by a cylindrical bushing that is mounted under pressure in each tubular projection of the hubcap, being retained therein by means of lateral projections of said additional piece that are interlocked in respective recesses provided for that purpose in the tubular projection, counting the own additional piece in its outer mouth with a flange that is positioned and butts on a small step of the flexible tabs. The additional part in question has, in correspondence with its lateral surface and in the direction of one of the generatrices, a projection that is located in a groove of the tubular projection, determining a single mounting position for said part, which is provided for its application in tubular projections in which all its tongues are flexible, although its application is also possible in those tubular projections that have flexible tongues between which fixed tongues are interspersed. In any case, the aforementioned additional piece has on the edge of its internal mouth with flexible pins that run between the tabs of the tubular projection, and on whose flexible pins adjusts the diameter corresponding to the protrusion of greater diameter with which the head is provided of the screw, with the function of centering and collaborating said pins in the positioning and fastening of the metal ring which, as an elastic element, maintains the tension of the flexible tabs of the tubular projection, preventing them from moving from their housing or position. The aforementioned additional piece will have a length greater than the grooves of the flexible tongues, ensuring that they are always covered, which improves the appearance of the hubcap, thus effectively fulfilling its function as a wheel bezel.

It shows a sectional view like the one in the previous figure but with the assembly carried out as the hubcap is retained on the fastening bolts of the rim.
DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERIDADESCRIPTION OF THE PREFERRED EMBODIMENT
A la vista de las figuras, puede observarse un tapacubos 1 con sus proyecciones tubulares 2 dotadas de lengüetas elásticas 3 en las que se conforman internamente labios 4, estando ese tapacubos 1, tal y como se representa en la figura 1, fijado sobre la correspondiente llanta 5 de la rueda. Dicha fijación se efectúa mediante tornillos 6 que quedan ubicados en las proyecciones tubulares 2, cuando se efectúa el empuje y deslizamiento del tapacubos 1 y por lo tanto de las proyecciones tubulares 2 sobre los tornillos 6 de fijación de la llanta 5, todo ello hasta que un resalte 7 de la cabeza del tornillo 6 hace tope contra un escalón 8 conformado en el labio 4 de las lengüetas flexibles 3 de las propias proyecciones tubulares 2.In view of the figures, a hubcap 1 can be seen with its tubular projections 2 provided with elastic tongues 3 in which lips 4 are formed internally, said hubcap 1 being, as shown in Figure 1, fixed on the corresponding 5 wheel rim. Said fixing is done by screws 6 which they are located in the tubular projections 2, when the push and slide of the hubcap 1 and therefore of the tubular projections 2 is carried out on the screws 6 for fixing the rim 5, all this until a protrusion 7 of the screw head 6 stops against a step 8 formed on the lip 4 of the flexible tongues 3 of the tubular projections 2.
Pues bien, a partir de estas características, la novedad de la invención consiste en la incorporación de una pieza adicional en forma de casquillo cilindrico 9, que se monta ajustadamente en cada una de las proyecciones tubulares 2, quedando retenida por medio de unas uñas 10 previstas en la superficie lateral de la propia pieza adicional 9 que se enclavan en escotaduras 11 correspondientes a las proyecciones tubulares 2, incluyendo además en su embocadura externa de mayor diámetro un reborde 12 que apoya y hace tope contra un pequeño escalón 13 previsto al efecto en una zona próxima a la embocadura de las proyecciones tubulares 2. La pieza adicional 9 cuenta, además, en su embocadura opuesta a la del reborde 12, con unas patillas 14 que internamente determinan una superficie de ajuste del reborde 7 correspondiente a la cabeza del tornillo 6, constituyendo un medio de centrado en el montaje, mientras que externamente esas patillas 14 determinan un medio de posicionado y retención para un aro elástico 15 que actúa como medio de compresión sobre las lengüetas flexibles 3 y, por supuesto, sobre las propias patillas 14.Well, from these characteristics, the novelty of the invention consists in the incorporation of an additional piece in the form of a cylindrical bushing 9, which is fitted tightly in each of the tubular projections 2, being retained by means of nails 10 provided on the lateral surface of the additional piece 9 that are interlocked in recesses 11 corresponding to the tubular projections 2, also including in its outer mouth of larger diameter a flange 12 that supports and abuts against a small step 13 provided for the purpose in an area close to the mouth of the tubular projections 2. The additional piece 9 also has, at its mouth opposite to that of the flange 12, with pins 14 that internally determine an adjustment surface of the flange 7 corresponding to the screw head 6, constituting a mounting centering means, while externally those pins 14 determine a positioning means and retain tion for an elastic ring 15 that acts as a compression means on the flexible tabs 3 and, of course, on the pins 14 themselves.
En la superficie lateral de la pieza adicional 9 se ha previsto un resalte 16 que condiciona el montaje de tal pieza 9 en una posición única al deslizarse ese resalte 16 en una ranura establecida al efecto en la correspondiente proyección tubular 2.On the side surface of the additional piece 9 a projection 16 is provided that conditions the assembly of such part 9 in a unique position when that projection 16 slides in a groove established for this purpose in the corresponding tubular projection 2.
De esta manera, una vez fijada la llanta 5 de la rueda mediante los tornillos 6, el montaje y sujeción del tapacubos 1 se realiza simplemente por empuje del mismo, haciendo previamente coincidentes las proyecciones tubulares 2 con los tornillos 6, empuje que lleva consigo el correspondiente desplazamiento o deslizamiento respecto a la cabeza de esos tornillos 6 hasta que se sobrepasa el resalte 7 para quedar enclavado el conjunto a través del escalón 8 definido en los labios 4 de las lengüetas flexibles 3 de las proyecciones tubulares 2, todo ello de manera tal que para la independización del tapacubos 1 es necesario llevar a cabo el desenroscado de los tornillos 6 ya que el enclavamiento entre el resalte 7 y escalón 8 impide la extracción del tapacubos.In this way, once the wheel rim 5 is fixed by means of screws 6, the assembly and fastening of the hubcap 1 is simply made by pushing it, previously making the tubular projections 2 coincident with the screws 6, a thrust that carries with it the corresponding displacement or sliding with respect to the head of those screws 6 until the projection 7 is exceeded to lock the set through the step 8 defined in the lips 4 of the flexible tabs 3 of the tubular projections 2, all in such a way that for the independence of the hubcap 1 it is necessary to carry out the unscrewing of the screws 6 since the interlocking between the shoulder 7 and step 8 prevents the removal of the hubcap.
La pieza adicional 9, aunque está prevista fundamentalmente para su aplicación en proyecciones tubulares 2 en la que la totalidad de sus lengüetas sean flexibles, es igualmente aplicable en aquellas proyecciones tubulares que incorporen intercaladas algunas lengüetas rígidas en las que ajustará el resalte anular 7 de la cabeza del tornillo 6, de manera que la no existencia de esas lengüetas rígidas establece que el apoyo y ajuste del resalte anular 7 se realice, como ya se ha dicho, sobre la parte interna de las patillas 14 pertenecientes a la propia pieza adicional 9. The additional piece 9, although it is essentially intended for application in tubular projections 2 in which all of its tabs are flexible, is equally applicable in those tubular projections that incorporate some rigid tabs intercalated in which the annular shoulder 7 of the screw head 6, so that the non-existence of these rigid tongues establishes that the support and adjustment of the annular shoulder 7 is carried out, as already said, on the internal part of the pins 14 belonging to the additional piece 9 itself.
