Description

APARATO LIMPIADOR DE BRACKETS ORTODONTICOS ORTHODONTIC BRACKET CLEANING DEVICE

CAMPO DE LA INVENCIÓNFIELD OF THE INVENTION

La presente invención se relaciona generalmente con dispositivos .para Ia limpieza de brackets ortodónticos. De manera particular, Ia presente invención está dirigida a un aparato para eliminar residuos de adhesivo de Ia superficie de brackets, botones palatinos y tubos de ortodoncia utilizados.The present invention relates generally to devices for cleaning orthodontic brackets. In particular, the present invention is directed to an apparatus for removing adhesive residues from the surface of brackets, palatal buttons and orthodontic tubes used.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En el inicio de Ia ortodoncia, el procedimiento utilizado para Ia colocación de brackets consistía en soldar brackets a una banda que se cementaba alrededor del diente. Con el paso del tiempo y el desarrollo de adhesivos para uso odontológico, se logro eliminar esta banda para cementar directamente los brackets a los dientes. Estos adhesivos poseen una fuerza adherente elevada que les permite funcionar bien en Ia unión adhesivo-esmalte y adhesivo-bracket. Las fallas comunes en dichos adhesivos están relacionadas con Ia contaminación de las superficies donde se aplica el adhesivo, mala manipulación de los brackets o falta de área de contacto de Ia unión. Con el fin de mantener los brackets en su posición por más tiempo, se colocó a los brackets una malla de alambre para aumentar el área de contacto en Ia unión adhesivo- bracket y crear una retención mecánica mejorada. Sin embargo, los brackets cementados presentan aún fallas en Ia fuerza adherente y por consecuencia desprenden. Cuando un bracket desprende de su unión bracket - adhesivo - esmalte, origina un retraso del tratamiento ortodóntico como es conocido por aquellos expertos en Ia técnica. El dentista tiene dos opciones para resolver este* problema: i) sustituir el bracket desprendido por uno nuevo, pero esto eleva el costo del tratamiento; o ii) tratar de recuperar el bracket desprendido retirando en su totalidad los residuos adhesivos que aún quedan adheridos en el bracket a fin de poder colocarlo nuevamente.At the beginning of the orthodontics, the procedure used for the placement of brackets consisted of welding brackets to a band that was cemented around the tooth. With the passage of time and the development of adhesives for dental use, it was possible to eliminate this band to directly cement the brackets to the teeth. These adhesives have a high adherent force that allows them to work well in the adhesive-enamel and adhesive-bracket joint. The common failures in said adhesives are related to the contamination of the surfaces where the adhesive is applied, bad manipulation of the brackets or lack of contact area of the joint. In order to keep the brackets in position for a longer time, a wire mesh was placed on the brackets to increase the contact area in the adhesive-bracket joint and create an improved mechanical retention. However, the cemented brackets still have failures in the adherent force and consequently detach. When a bracket detaches from its bracket - adhesive - enamel joint, it causes a delay in orthodontic treatment as is known by those skilled in the art. The dentist has two options to solve this * problem: i) replace the detached bracket with a new one, but this raises the cost of treatment; or ii) try to recover the detached bracket by removing in all the adhesive residues that are still adhered to the bracket in order to be able to place it again.

Se han llevado a cabo diferentes formas para retirar el residuo de adhesivo de las superficies del bracket: - Limpieza por exposición directa al fuego. Este tipo de limpieza posee ciertos i inconvenientes que derivan de Ia exposición directa del bracket a altas temperaturas producidas por Ia flama de un quemador, debido a que aunque el adhesivo se quema y es fácil retirarlo de Ia superficie del bracket, el metal del bracket alcanza una temperatura tan elevada que cambia de color y resulta en Ia alteración de ciertas propiedades del metal tales como, por ejemplo su dureza y, como consecuencia, el bracket una vez colocado en posición no va a trabajar con las fuerzas aplicadas por alambres de Ia misma manera que el resto de los brackets del paciente originalmente cementados. El bracket al tener alterada su dureza a causa del tratamiento térmico, no transmite directamente al diente las fuerzas que Ie son aplicadas, sino que el bracket limpiado sufre una flexión. Es decir, el bracket absorbe parte de Ia fuerza que debería de ser aplicada al diente.Different ways have been carried out to remove adhesive residue from the surfaces of the bracket: - Cleaning by direct exposure to fire. This type of cleaning has certain disadvantages that derive from the direct exposure of the bracket at high temperatures caused by the flame of a burner, because although the adhesive burns and it is easy to remove it from the surface of the bracket, the bracket metal reaches a temperature so high that it changes color and results in the alteration of certain properties of the metal such as, for example, its hardness and, as a consequence, the bracket once placed in position will not work with the forces applied by wires thereof so that the rest of the patient's braces originally cemented. The bracket having its hardness altered due to heat treatment, does not directly transmit to the tooth the forces that are applied, but the cleaned bracket undergoes a flexion. That is, the bracket absorbs part of the force that should be applied to the tooth.

- Limpieza por medios mecánicos. Para recuperar el bracket desprendido y contaminado con residuos de adhesivo, el adhesivo es retirado por medios mecánicos giratorios tal como por medio de una fresa. Este procedimiento resulta muy laborioso e impreciso debido a que es imposible cortar el adhesivo que está adherido entre Ia malla de alambre porque Ia fresa es mucho mas grande que Ia retícula de estas mallas. Además, los medios mecánicos reducen enormemente el área de contacto y elimina ía retención mecánica Io que significa que al colocar de nuevo este bracket se va a caer varias veces durante el tratamiento.- Cleaning by mechanical means. To recover the bracket detached and contaminated with adhesive residue, the adhesive is removed by rotating mechanical means such as by means of a milling cutter. This procedure is very laborious and inaccurate because it is impossible to cut the adhesive that is adhered between the wire mesh because the milling cutter is much larger than the grid of these meshes. In addition, the mechanical means greatly reduce the contact area and eliminate mechanical retention, which means that when this bracket is repositioned it will fall several times during the treatment.

- Limpieza con Chorro de Arena ("Sandblast"). Aunque esta forma de limpieza es Ia más viable por no degradar Ia dureza del metal, no reducir el área de contacto y permitir Ia eliminación de los residuos adhesivos de entre Ia malla de alambre, aún presenta algunos inconvenientes. El bracket con residuos de adhesivo se introduce en una cabina de limpieza con chorro de arena en donde se aplica un baño de arena a presión directamente sobre la superficie de! bracket que presenta los residuos de adhesivo. Sin embargo, debido a las dimensiones del bracket resulta muy difícil manipularlo dentro de Ia cabina, independientemente que Ia visión que se puede tener dentro de la cabina es muy limitada. En consecuencia, no se puede obtener un control del chorro de arena y por tanto Ia arena además de retirar los restos de adhesivo, golpea Ia cara vestibular del bracket que produce una superficie rugosa.' Una superficie rugosa en la cara vestibular del bracket se traduce en un incremento en Ia fuerza de fricción que Umita el deslizamiento del bracket sobre el alambre, Io cual resulta en menor movimiento del diente al que se le coloca este bracket limpiado en comparación con el resto de los dientes prologando el tratamiento de esta manera.- Sandblast cleaning ("Sandblast"). Although this form of cleaning is the most viable because it does not degrade the hardness of the metal, does not reduce the contact area and allows the elimination of adhesive residues between the wire mesh, it still has some drawbacks. The bracket with adhesive residue is inserted into a cleaning booth with sandblasting where a pressure sand bath is applied directly on the surface of! bracket that presents adhesive residue. However, due to the dimensions of the bracket it is very difficult to manipulate it inside the cabin, regardless that the vision that can be had inside the cabin is very limited. Consequently, it is not possible to obtain a control of the sandblasting and therefore the sand in addition to removing the remains of adhesive, strikes the vestibular face of the bracket that produces a rough surface. ' A rough surface on the vestibular face of the bracket translates into an increase in the frictional force that prevents the sliding of the bracket on the wire, which results in less movement of the tooth to which this cleaned bracket is placed compared to the rest of the teeth prolonging the treatment in this way.

El principio de limpieza o tratamiento con chorro de arena o "sandblast" consiste en mezclar partículas o cuerpos abrasivos (por ejemplo, arena) con un flujo de gas o aire, el cual acelerará estas partículas impactándolas contra una superficie, provocando una erosión o abrasión sobre Ia superficie impactada. Este principio ha sido ampliamente utilizado en Ia industria en general tal como, por ejemplo, para limpieza de superficies, recubrimiento de materiales, proporcionar acabados, corte de materiales, etc.The principle of cleaning or treatment with sandblasting or sandblast consists in mixing particles or abrasive bodies (for example, sand) with a flow of gas or air, which will accelerate these particles by impacting them against a surface, causing erosion or abrasion. on the impacted surface. This principle has been widely used in the industry in general such as, for example, for surface cleaning, coating of materials, providing finishes, cutting of materials, etc.

Haciendo ciertos ajustes de operación tales como variando Ia presión a Ia que trabaja o el abrasivo utilizado, cualquiera de los dispositivos descritos en las patentes anteriores serían útiles para eliminar los residuos de adhesivo y limpiar un bracket. Sin embargo, aún presentan ciertos inconvenientes. Uno de los inconvenientes que poseen estos dispositivos es Ia dificultad para sujetar y retener un bracket contaminado con adhesivo en posición ya que es tan pequeño que resulta difícil su manipulación y es probable que el abrasivo ataque Ia superficie vestibular del bracket, eliminando el acabado pulido que debe tener esta cara. Un segundo inconveniente consiste en qué ninguno de estos dispositivos cuenta con un contenedor o depósito para recolectar el abrasivo ya utilizado. La, mezcla de abrasivo con gas sale por Ia boquilla del dispositivo, luego se impacta contra el bracket y el abrasivo rebota, pero al no existir ningún contenedor o depósito que reciba el abrasivo utilizado, este quedará disperso en el medio ambiente. El abrasivo disperso en el medio ambiente implica que, por un lado, tanto el dentista como el paciente estarán respirando este abrasivo y, por el otro lado, el abrasivo se depositará sobre todas las superficies del consultorio o área de trabajo.By making certain operation adjustments such as varying the pressure at which it works or the abrasive used, any of the devices described in the previous patents would be useful for removing adhesive residues and cleaning a bracket. However, they still have certain drawbacks. One of the disadvantages that these devices have is the difficulty in holding and retaining a bracket contaminated with adhesive in position since it is so small that it is difficult to manipulate and it is likely that the abrasive attack the vestibular surface of the bracket, eliminating the polished finish that You must have this face. A second drawback is that none of these devices have a container or reservoir to collect the abrasive already used. The mixture of abrasive with gas leaves the nozzle of the device, then hits the bracket and the abrasive bounces, but since there is no container or deposit that receives the abrasive used, it will be dispersed in the environment. The abrasive dispersed in the environment implies that, on the one hand, both the dentist and the patient will be breathing this abrasive and, on the other hand, the abrasive will be deposited on all surfaces of the office or work area.

Existen dispositivos de tratamiento con chorro de arena o "sandblasters" para uso en trabajos de laboratorio dental, los cuales comprenden cabinas cerradas del tipo divulgadas en las patentes DE 4325608 de Bramer WoIf; US 3,815,286 de Piet; JP 2005 218637 de Takeuchi Hirosato; DE 4122980 de Pueschner G; EP 0 643 947 de Puüfarcken UIf, US 3,631 ,631 de Jean I Greenstein. Estos dispositivos no presentan el inconveniente de diseminar el abrasivo hacia el medio ambiente ya que todo el abrasivo es confinado en el interior del gabinete. Sin embargo, esta clase de dispositivos aún presenta el inconveniente de no manipular en forma adecuada el bracket durante su limpieza y, en este caso, su manipulación posee una mayor dificultad porque los gabinetes tienen dos orificios por donde el operario introduce las manos, Io que resta movilidad. Además, estas cabinas cuentan con una ventana o mirrilla por donde se puede ver al interior del gabinete pero al ser de vidrio o de algún plástico transparente no resistente a los impactos se raya fácilmente por Ia acción del abrasivo, Io cual dificulta Ia visión elevando el riesgo de atacar Ia cara vestibular de bracket de tal manera que es muy difícil limpiar un bracket en estos dispositivos.There are sandblasting or sandblasting treatment devices for use in dental laboratory work, which include closed cabins of the type disclosed in Bramer WoIf DE 4325608 patents; US 3,815,286 by Piet; JP 2005 218637 of Takeuchi Hirosato; DE 4122980 of Pueschner G; EP 0 643 947 from Puüfarcken UIf, US 3,631, 631 by Jean I Greenstein. These devices do not have the disadvantage of spreading the abrasive towards the environment since all the abrasive is confined inside the cabinet. However, this class of devices still has the disadvantage of not properly manipulating the bracket during cleaning and, in this case, its handling has a greater difficulty because the cabinets have two holes through which the operator inserts the hands, which subtract mobility. In addition, these cabins have a window or peephole where you can see inside the cabinet but being made of glass or some transparent non-impact resistant plastic is easily scratched by the action of the abrasive, which makes vision difficult by raising the risk of attacking the vestibular bracket face in such a way that it is very difficult to clean a bracket in these devices.

Teniendo en cuenta las desventajas de Ia técnica anterior, es un objeto de Ia presente invención proporcionar un aparato para retirar el residuo de adhesivo de un bracket para su reutilización que tanga un control de Ia dirección del flujo de arena.Taking into account the disadvantages of the prior art, it is an object of the present invention to provide an apparatus for removing the adhesive residue from a bracket for reuse that controls the sand flow direction.

Preferiblemente, ei cuerpo principal 11 define en su interior una cavidad o cámara 32 para alojar y contener un material abrasivo que será utilizado en y durante el proceso de limpieza y eliminación de residuos de adhesivo de acuerdo con Ia presente invención. La cubierta 12 tiene una forma cilindrica abierta por el fondo para alojar los componentes operativos del aparato limpiador de brackets 10 como se discutirá en detalle más abajo.An apparatus for cleaning and removing adhesive residues from the surface of brackets, palatal buttons and orthodontic tubes used, of the present invention, is shown in Figure 1. As shown in Figure 1, the apparatus 10 comprises a main body or base member 11 constituting the lower part of the apparatus 10 and an upper cover or complementary cover member 12 covering the main body 11 to close the apparatus 10. The main body 11 is a hollow cylindrical body closed by one end forming a bottom or base wall. Preferably, the main body 11 defines in its interior a cavity or chamber 32 for housing and containing an abrasive material that will be used in and during the process of cleaning and removing adhesive residues according to the present invention. The cover 12 has a cylindrical shape open at the bottom to accommodate the operating components of the bracket cleaning apparatus 10 as will be discussed in detail below.

El cuerpo principal 11 del aparato limpiador tiene una pared circunferencial y una pared de fondo. La pared circunferencial, incluye una porción rebajada que tiene una pluralidad de roscas, en donde Ia porción rebajada se ubica en Ia parte superior externa de Ia pared circunferencial Ia cual extiende hacia abajo. Típicamente, Ia cubierta superior 12 del aparato limpiador comprende una pared superior que tiene un grosor y configuración particular para alojar los componentes operativos del aparato limpiador de brackets 10 como se discutirá en detalle más abajo, y una pared lateral que se extiende circunferencialmente hacia debajo de Ia pared superior e incluye una porción rebajada que presenta una pluralidad de roscas, en donde Ia porción rebajada está formada en Ia parte inferior interna de Ia cubierta superior 12 y en donde Ia pluralidad de roscas de Ia cubierta superior 12 son complementarias para acoplar Ia pluralidad de roscas de Ia parte superior externa de Ia pared circunferencial del cuerpo principal 11 del aparato limpiador. Sin embargo, aquellos expertos en Ia técnica apreciarán que Ia pluralidad de roscas ubicadas en Ia parte superior externa del cuerpo principal 11 y en Ia parte inferior interna de Ia cubierta 12 puede substituirse por un sistema de cierre a presión formado por un reborde y un rebajo circunferencialmente formados para permitir el ajuste a presión de Ia cubierta superior 12 al cuerpo principal 11.The main body 11 of the cleaning apparatus has a circumferential wall and a bottom wall. The circumferential wall includes a recessed portion that has a plurality of threads, wherein the recessed portion is located in the upper outer part of the circumferential wall which extends downward. Typically, the upper cover 12 of the cleaning apparatus comprises an upper wall having a particular thickness and configuration for housing the operative components of the bracket cleaning apparatus 10 as will be discussed in detail below, and a side wall that extends circumferentially below the upper wall and includes a recessed portion that has a plurality of threads, wherein the recessed portion is formed in the lower internal part of the upper cover 12 and where the plurality of threads of the upper cover 12 are complementary to couple the plurality of threads of the upper external part of the circumferential wall of the main body 11 of the cleaning apparatus. However, those skilled in the art will appreciate that the plurality of threads located in the upper outer part of the main body 11 and in the lower inner part of the cover 12 can be replaced by a snap closure system formed by a flange and a recess circumferentially formed to allow pressure adjustment of the upper cover 12 to the main body 11.

Como se observa en las Figuras 1 y 2, el acoplamiento de cierre que se forma al enroscar las porciones rebajadas Interna y externa de Ia cubierta superior 12 y el cuerpo principal 11 , respectivamente, del aparato limpiador 10 crea un espacio de soporte 30 que da hacia Ia cámara 32 del cuerpo principal 11. Un miembro de sellado 3 está internamente dispuesto entre el cuerpo principal 11 y Ia cubierta superior 12, en donde el miembro de sellado 3 apoya sobre y es retenido dentro del espacio de soporte 30 para formar de esta manera un sello- hermético entre Ia cubierta superior 12 y el cuerpo principal 11. Preferiblemente, el miembro de sellado 3 protege además Ia superficie interna superior del aparato 10 contra Ia abrasión que resulta del flujo del material abrasivo durante el procedimiento de limpieza.As can be seen in Figures 1 and 2, the closing coupling that is formed by screwing the internal and external recessed portions of the upper cover 12 and the main body 11, respectively, of the cleaning apparatus 10 creates a support space 30 which gives towards the chamber 32 of the main body 11. A sealing member 3 is internally disposed between the main body 11 and the upper cover 12, wherein the sealing member 3 rests on and is retained within the support space 30 to form of this a tight seal between the upper cover 12 and the main body 11. Preferably, the sealing member 3 also protects the upper inner surface of the apparatus 10 against abrasion resulting from the flow of the abrasive material during the cleaning process.

El miembro de sellado 3 es de forma cilindrica e incluye un reborde 33 que se extiende circunferencialmente sóbre la superficie extema del miembro de sellado 3, en donde dicho reborde 33 posee un tamaño y forma apropiados para apoyar y ser retenido dentro de dicho espacio de soporte 30 formado por el acoplamiento de cierre del cuerpo principal 11 y Ia cubierta 12. El miembro de sellado 3 presenta un diámetro ligeramente menor que el diámetro interno del aparato limpiador 10 que Ie permite encajar fácilmente y proteger así Ia superficie superior interna del mismo. El miembro de sellado 3 tiene un extremo superior 34 y un extremo inferior 31. En una modalidad preferida, ia pared superior de Ia cubierta superior 12 incluye una porción internamente rebajada de manera circunferencial 100. De preferencia, el extremo superior 34 del miembro de sellado 3 encaja en Ia porción rebajada 100 de Ia superficie interna de Ia cubierta 11 , en tanto que el extremo inferior 31 se extiende a una cierta distancia por debajo de Ia interfaz del cierre formado por dicha cubierta 12 y el cuerpo principal 12 del aparato limpiador 10. Como se observa, el extremo inferior 31 incluye una pestaña de retención radialmente formada 35. La pestaña de retención 35 del extremo inferior del miembro de sellado 3 soporta un miembro colador de material abrasivo 14.The sealing member 3 is cylindrical in shape and includes a flange 33 that extends circumferentially over the outer surface of the sealing member 3, wherein said flange 33 has an appropriate size and shape to support and be retained within said support space 30 formed by the closing coupling of the main body 11 and the cover 12. The sealing member 3 has a diameter slightly smaller than the internal diameter of the cleaning apparatus 10 which allows it to easily fit and thus protect the internal upper surface thereof. The sealing member 3 has an upper end 34 and an end lower 31. In a preferred embodiment, the upper wall of the upper cover 12 includes an internally circumferentially recessed portion 100. Preferably, the upper end 34 of the sealing member 3 fits into the recessed portion 100 of the internal surface of the cover 11, while the lower end 31 extends a certain distance below the interface of the closure formed by said cover 12 and the main body 12 of the cleaning apparatus 10. As can be seen, the lower end 31 includes a flange of radially formed retainer 35. The retaining flange 35 of the lower end of the sealing member 3 supports a strainer member of abrasive material 14.

El miembro colador de material abrasivo 14 es de forma circular plana que posee una pluralidad de aberturas (no mostradas). El tamaño de las aberturas del miembro colador 14 se selecciona de tal manera que solo permite el paso de las partículas del material abrasivo durante la operación de limpieza para Ia reutilización de las mismas, mientras que retiene los residuos de resina o adhesivo retirados del bracket para su desecho. Además, el miembro colador 14 se utiliza para evitar que cualquier elemento de mayor tamaño (por ejemplo, bracket, etc.,) o componente del aparato caiga al fondo de Ia cámara 32 del cuerpo principal 11 ; con Io cual se facilita Ia recuperación del bracket o componente del aparato 10 tal como, por ejemplo, un émbolo sujetador de brackets.The abrasive material strainer member 14 is of a circular circular shape having a plurality of openings (not shown). The size of the openings of the strainer member 14 is selected in such a way that it only allows the particles of the abrasive material to pass during the cleaning operation for the reuse thereof, while retaining the resin or adhesive residues removed from the bracket for Your scrap In addition, the strainer member 14 is used to prevent any larger element (for example, bracket, etc.,) or component of the apparatus from falling to the bottom of the chamber 32 of the main body 11; with which the recovery of the bracket or component of the apparatus 10 is facilitated, such as, for example, a bracket holding plunger.

Haciendo referencia de nuevo a Ia Figura 2, se observa que Ia cubierta superior 12 incluye un orificio de montaje 40 de un miembro sujetador de brackets 41 , un orificio de montaje 42 de un conjunto alimentador de aire a presión 110, un orificio de conexión 43 de una fuente de alimentación de aire a presión 9 del aparato limpiador 10 en comunicación de fluido con el conjunto alimentador de aire 110, y un conducto de salida de aire 16 (mostrado en Ia Figura 3) para desfogar el aire producido durante Ia operación de limpieza. El miembro sujetador de bracket 41 se inserta en el orificio de montaje 42 de Ia cubierta 12 para situar un bracket en posición para ser impactado con el material abrasivo durante el procedimiento de limpieza, en donde el miembro sujetador 41 tiene porción externa de manipulación 44 y una porción interna de sujeción 44. La porción externa de manipulación 44 permite manipular el miembro sujetador de bracket 41 para insertarlo o extraerlo durante Ia operación de limpieza de brackets. En una modalidad preferida, Ia porción interna de sujeción 45 del miembro sujetador presenta una porción ahuecada cuyas dimensiones son proporcionales al tamaño de un bracket (no ilustrado). Además, Ia porción ahuecada de Ia porción interna de sujeción 45 comprende un material pegajoso (por ejemplo, silicón) para mantener inmóvil y en posición al bracket dentro de Ia misma durante su limpieza. En una modalidad alterna preferida, Ia porción externa de manipulación 44 del miembro sujetador de bracket 41 comprende medios indicadores de Ia orientación correcta de Ia porción ahuecada del miembro sujetador de bracket 41 que será sometido a limpieza por medio del flujo de material abrasivo a presión. Como se describió anteriormente, típicamente Ia cubierta 12 aloja también un conjunto alimentador de aire a presión 110 a través del orificio de montaje 42 que está en comunicación del fluido con el orificio de conexión 43 de Ia fuente de alimentación de aire comprimido. Preferentemente, el conjunto alimentador de aire a presión 110 comprende un miembro regulador de flujo 7 tal como, por ejemplo una válvula dispuesta dentro del orificio de montaje 42, en donde el miembro regulador de flujo 7 puede ser un vastago que tiene un orificio 50 que se extiende longitudinalmente desde Ia pared lateral del vastago hacia su parte central y luego perpéndicularmente hacia abajo para permitir el paso de aire a través de dicho, miembro regulador de flujo 7, y una pluralidad de pares de resaltes circunferenciales 111 dispuestos de manera separada a Io largo de Ia extensión del miembro regulador de flujo 7; una pluralidad de empaques 8 situados dentro de cada par de resaltes 111 de tal manera que forman un sellado hermético que impide que el aire á presión salga del conjunto alimentador de aire 110 por las uniones de éste con Ia cubierta 12; y una perilla de accionamiento 6 acoplada en Ia parte superior del miembro regulador de flujo 7 para presionar dicho miembro regulador de flujo 7 y accionar el conjunto alimentador de aire 110. El aparato limpiador de brackets de Ia presente invención comprende además un ensamble formador de mezcla aire - material abrasivo 120. El ensamble formador de ía mezcla aire - material abrasivo 120 está dispuesto debajo de y en comunicación de fluido con el conjunto alimentador de aire 110. Como se observa en las Figuras 1 y 2, el ensamble formador de mezcla aire - material abrasivo 120 tiene una base de cámara 121 que se ubica adyacente y en comunicación de fluido con el orificio de montaje 42 del lado que da hacia Ia cámara 32 donde se aloja el material abrasivo, en donde Ia base de cámara 121 se coloca de manera fija adyacente al orificio de montaje 42 por cualquier medio adecuado. La base de cámara 121 funciona como un tope inferior para el miembro regulador de flujo 7 debido a que dicha base de cámara 121 tiene un orificio 60 con un diámetro menor que el diámetro del miembro regulador de flujo 7, por Io que puede utilizarse el orificio 60 como asiento de válvula para el miembro regulador de flujo 7. La base de cámara 121 del ensamble formador de mezcla aire - material abrasivo 120 incluye un segundo orificio 62 en comunicación de fluido con el primer orificio 60, el cual forma un ángulo de 90 grados con el orificio 60, en donde el segundo orificio 62 de Ia base de cámara 121 se utiliza como base para disponer un miembro mezclador de aire - material abrasivo.Referring again to Figure 2, it can be seen that the upper cover 12 includes a mounting hole 40 of a bracket fastener member 41, a mounting hole 42 of a pressurized air feed assembly 110, a connection hole 43 of a pressurized air power supply 9 of the cleaning apparatus 10 in fluid communication with the air supply assembly 110, and an air outlet duct 16 (shown in Figure 3) to vent the air produced during the operation of cleaning. The bracket fastener member 41 is inserted into the mounting hole 42 of the cover 12 to place a bracket in position to be impacted with the abrasive material during the cleaning procedure, wherein the fastener member 41 has an external handling portion 44 and an internal holding portion 44. The external handling portion 44 allows manipulating the bracket clamp member 41 for insertion or removal during the bracket cleaning operation. In a preferred embodiment, the internal clamping portion 45 of the clamping member has a recessed portion whose dimensions are proportional to the size of a bracket (not shown). In addition, the recessed portion of the internal clamping portion 45 comprises a sticky material (for example, silicone) to keep the bracket immobile and in position during cleaning. In a preferred alternate embodiment, the external handling portion 44 of the bracket fastener member 41 comprises indicating means of the correct orientation of the recessed portion of the bracket fastener member 41 that will be subjected to cleaning by means of the flow of abrasive material under pressure. As described above, typically the cover 12 also houses a pressurized air feed assembly 110 through the mounting hole 42 that is in communication of the fluid with the connection hole 43 of the compressed air supply source. Preferably, the pressurized air feeder assembly 110 comprises a flow regulator member 7 such as, for example, a valve disposed within the mounting hole 42, wherein the flow regulator member 7 may be a rod having a hole 50 which it extends longitudinally from the side wall of the rod towards its central part and then perpendicularly downwards to allow the passage of air through said flow regulating member 7, and a plurality of pairs of circumferential projections 111 arranged separately to Io along the extension of the flow regulating member 7; a plurality of gaskets 8 located within each pair of projections 111 in such a way that they form a hermetic seal that prevents the pressurized air from leaving the air supply assembly 110 by the joints thereof with the cover 12; and an actuation knob 6 coupled in the upper part of the flow regulator member 7 to press said flow regulator member 7 and actuate the air feed assembly 110. The bracket cleaning apparatus of the present invention further comprises a mixing forming assembly air - abrasive material 120. The air mixing assembly - abrasive material 120 is disposed below and in fluid communication with the air feed assembly 110. As seen in Figures 1 and 2, the air-abrasive material forming assembly 120 has a chamber base 121 that is located adjacent and in fluid communication with the mounting hole 42 on the side that it gives towards the chamber 32 where the abrasive material is housed, wherein the chamber base 121 is fixedly positioned adjacent to the mounting hole 42 by any suitable means. The chamber base 121 functions as a lower stop for the flow regulator member 7 because said chamber base 121 has a hole 60 with a diameter smaller than the diameter of the flow regulator member 7, whereby the hole can be used 60 as a valve seat for the flow regulating member 7. The chamber base 121 of the air-abrasive material forming assembly 120 includes a second hole 62 in fluid communication with the first hole 60, which forms an angle of 90 degrees with the hole 60, wherein the second hole 62 of the chamber base 121 is used as the base for arranging an air mixing member - abrasive material.

El miembro mezclador de aire - material abrasivo comprende una porción de montaje 131 para montar el miembro mezclador en el orificio 62 de (a base de cámara 120; una boquilla de surtido 133 para dispensar Ia mezcla de aire - material- abrasivo a presión contra el bracket que será limpiado; y una porción de cámara 132 dispuesta entre Ia porción de montaje 131 y Ia boquilla de surtido 133. La porción de montaje 131 se acopla por uno de sus extremos al segundo orificio 62 de Ia base de cámara 121 , en donde Ia porción de montaje 131 además mantener en posición al miembro mezclador de aire - material abrasivo tiene como función elevar Ia presión del aire que es conducido a través de éste hacia Ia porción de cámara 132.The air-abrasive material mixing member comprises a mounting portion 131 for mounting the mixing member in the hole 62 of (chamber-based 120; an assortment nozzle 133 for dispensing the air-material-abrasive mixture under pressure against the bracket that will be cleaned, and a chamber portion 132 disposed between the mounting portion 131 and the assortment nozzle 133. The mounting portion 131 is coupled at one of its ends to the second hole 62 of the chamber base 121, where The mounting portion 131 also keeps the air mixing member - abrasive material in position has the function of raising the pressure of the air that is conducted through it towards the chamber portion 132.
