La solicitud de patente europea EP-A-1000600 describe un mecanismo que posibilita impartir distintos tipos de masaje a la parte inferior de las piernas de un usuario, mediante un mecanismo de masaje que comprende un eje giratorio, una pareja de rodillos de masaje derecho e izquierdo montados en una parte intermedia del eje giratorio de forma inclinada con respecto a un eje geométrico del eje giratorio, medios de accionamiento para accionar giratoriamente el eje giratorio, así como medios conmutadores para selectivamente conmutar la posición de los rodillos de masaje derecho e izquierdo, hacia una posición de amasamiento en la que los rodillos de masaje están inclinados opuestamente el uno al otro, y a una posición de no-amasamiento en la que los rodillos de masaje están inclinados paralelamente entre sí. Si bien este mecanismo permite impartir masajes de amasamiento y de no- amasamiento a las piernas del usuario, presenta el inconveniente de que ello se consigue a través de un mecanismo relativamente complicado para cada pierna del usuario .Efficient massage, has the disadvantage of providing a single type of kneading massage imparted simultaneously and equally to both legs of the user, which results in offering little variation to the user. European patent application EP-A-1000600 describes a mechanism that makes it possible to impart different types of massage to the lower part of a user's legs, by means of a massage mechanism comprising a rotating shaft, a pair of right massage rollers and left mounted on an intermediate part of the rotating shaft inclined with respect to a geometric axis of the rotating shaft, drive means for rotating the rotating shaft, as well as switching means for selectively switching the position of the right and left massage rollers, towards a kneading position in which the massage rollers are inclined opposite to each other, and to a non-kneading position in which the massage rollers are inclined parallel to each other. Although this mechanism allows to impart kneading and non-kneading massages to the user's legs, it has the disadvantage that this is achieved through a relatively complicated mechanism for each leg of the user.
Era, por tanto, deseable poder disponer de un mecanismo que permitiera ofrecer al usuario más tipos de masaje de las partes inferiores de sus piernas que los que ofrecen los mecanismos convencionales, y que a la vez no presentara una estructura tan compleja como la del mecanismo descrito en la solicitud de patente europea EP-A-10000600. También puede citarse el documento de Patente japonesaIt was, therefore, desirable to be able to have a mechanism that allowed the user to offer more types of massage of the lower parts of his legs than those offered by conventional mechanisms, and that at the same time did not present such a complex structure as the mechanism described in European patent application EP-A-10000600.

JP 2003-665, en el que los elementos de masaje están constituidos por parejas de láminas alargadas dispuestas en planos inclinados respecto al eje giratorio de forma que se mueven cambiando el grado de inclinación respecto a la longitud de la parte a masajear. Además entre las láminas alargadas se ha previsto la incorporación de un elemento de masaje intermedio que está constituido por una base, uno de cuyos extremos está sujeto a un resorte y además apoya en una leva prevista en el eje giratorio; todo ello para producir un movimiento ascendente-descendente de la base y en consecuencia de, la pierna del usuario, ya que ésta se ubica entre las láminas alargadas y apoya sobre la base del elemento de masaje intermedio, por lo que se modifica la posición de la pierna respecto a las láminas alargadas al subir o bajar la pierna del usuario por el efecto del movimiento de la base.JP 2003-665, in which the massage elements are constituted by pairs of elongated sheets arranged in inclined planes with respect to the rotating axis so that they move by changing the degree of inclination with respect to the length of the part to be massaged. Also between the sheets Elongated, the incorporation of an intermediate massage element is provided, which is constituted by a base, one of whose ends is attached to a spring and also supports a cam provided on the rotating shaft; all this to produce an upward-downward movement of the base and, consequently, of the user's leg, since this is located between the elongated sheets and supports on the base of the intermediate massage element, whereby the position of the leg with respect to the elongated sheets when raising or lowering the user's leg due to the effect of the movement of the base.
En este caso el elemento de masaje intermedio utilizado presenta el inconveniente de que a partir de una posición horizontal el movimiento ascendente provoca una variación de la zona de masaje lateralmente, pero no sobre la parte posterior de la pierna, y no consigue el efecto deseado, ya que el desplazamiento realizado tiene un efecto que difiere sustancialmente del provocado por un masajista, lo que constituye un inconveniente. DESCRIPCIÓN DE LA INVENCIÓNIn this case the intermediate massage element used has the disadvantage that from a horizontal position the upward movement causes a variation of the massage area laterally, but not on the back of the leg, and does not achieve the desired effect, since the displacement made has an effect that differs substantially from that caused by a masseuse, which constitutes an inconvenience.

Los discos de cada pareja de discos son giratorios para lo que están fijos a su eje, o también pueden estar sujetos al eje mediante una excéntrica y unidos a un punto fijo para impedir su giro.The object of the present invention is to overcome the drawbacks of the state-of-the-art mechanisms by means of a mechanism that, in a conventional manner, comprises a first pair of eccentrically supported massage disks on a first rotating axis, at a distance from each other to massage opposite sides of the lower part of a first leg of the user, the disks of the first pair of discs being arranged in inclined foregrounds with respect to the first rotating axis, as well as a second pair of eccentrically supported massage disks in a second rotating shaft, at a distance from each other to massage opposite sides of the lower part of a second leg of the user, the disks of the second pair of discs being arranged in second inclined planes with respect to the second rotating axis, and in the that the axes Rotary are connected to a drive mechanism capable of conferring a rotation to said rotating axes in a first direction of rotation and in a second direction of rotation opposite to the first direction of rotation, whose mechanism, according to the invention, further comprises at least a clutch mechanism with at least one internal housing comprising a first abutment element and a second abutment element, an arcuate vertical section passage between said abutment elements, and a projection between said abutments, bumping the projection against one or the other. of the stop elements depending on the direction of rotation of the rotating shafts; a first end portion of at least the second rotating shaft engaged in the clutch mechanism housing; where the passage and the stop elements are arranged in a plane perpendicular to the longitudinal axis of the rotating axes; the passage is a recess selected from an outer recess formed in a part of the outer perimeter of the first end part of the second rotating shaft and an inner recess in a part of an internal wall of the housing in which said first end part of the second is coupled rotating shaft; the projection is selected from an inner projection that emerges from the inner perimeter of the housing, and an outer projection that emerges from the outer perimeter of the first end part of the second rotating axis; and the abutment elements and the projection are arranged such that the projection contacts one of the abutment elements when the rotating shafts rotate in said first direction, and contacts the opposite abutment element when the rotating shafts rotate in said second direction. . The discs of each pair of discs are rotatable to which are fixed to its axis, or they can also be attached to the axis by means of an eccentric and connected to a fixed point to prevent its rotation.
Esta disposición de elementos permite que, en dependencia del sentido de rotación de los ejes giratorios, los discos de la primera pareja de discos de masaje del primer eje giratorio y los discos de la segunda pareja de discos del segundo eje giratorio se encuentren en posiciones idénticas o en posiciones desfasadas y hasta inversas. De esta manera y en dependencia del sentido de rotación, las parejas de discos de masaje pueden realizar un masaje de amasamiento en la misma parte de cada pierna del usuario o en alturas diferentes de la pierna respectiva, es decir, realizando durante una vuelta de los ejes el masaje en una parte más elevada de la primera pierna mediante la primera pareja de discos y el masaje en la otra pierna en una parte más baja mediante la segunda pareja de discos, y realizando en la siguiente vuelta de los ejes giratorios los masajes respectivos en posiciones inversas. En una primera realización de la invención, el mecanismo de embrague es solidario al primer extremo del primer eje giratorio, mientras que en una segunda realización de la invención el mecanismo de embrague permite el giro del primer extremo del primer eje giratorio en el paso de sección arqueada. En ambas realizaciones, el mecanismo de embrague puede estar dispuesto entre el primer eje giratorio y la primera parte extrema del segundo eje giratorio, estando entonces la primera parte extrema del segundo eje giratorio acoplada en el alojamiento. Alternativamente, el mecanismo de accionamiento puede estar conectado a una segunda parte extrema de uno de los ejes giratorios. Sin embargo, en la primera realización, es de decir, cuando el embrague es solidario al primer extremo del primer eje giratorio, la primera parte extrema del primer eje giratorio está acoplada fijamente al mecanismo de embrague, y la primera parte extrema del segundo eje giratorio está acoplada en el alojamiento. El paso de sección vertical arqueada puede tener una extensión de un arco de entre 40 y 270°, particularmente entre 160 y 200°, preferentemente entre 170 y 190° y más preferentemente de aproximadamente 180°.This arrangement of elements allows, depending on the direction of rotation of the rotating shafts, the disks of the first pair of massage disks of the first rotating shaft and the disks of the second pair of disks of the second rotating shaft are in identical positions. or in outdated and even inverse positions. In this way and depending on the direction of rotation, couples of massage discs can perform a kneading massage on the same part of each leg of the user or at different heights of the respective leg, that is, performing during a turn of the axes the massage in a higher part of the first leg by the first pair of discs and the massage in the other leg in a lower part by the second pair of discs, and performing the respective massages on the next turn of the rotating axes in reverse positions. In a first embodiment of the invention, the clutch mechanism is integral with the first end of the first rotating shaft, while in a second embodiment of the invention the clutch mechanism allows the first end of the first rotating shaft to rotate in the section passage arched In both embodiments, the clutch mechanism may be disposed between the first rotating shaft and the first end portion of the second rotating shaft, then the first end portion of the second rotating shaft is coupled in the housing. Alternatively, the drive mechanism may be connected to a second end portion of one of the rotating shafts.

The arched vertical section passage may have an arc extension of between 40 and 270 °, particularly between 160 and 200 °, preferably between 170 and 190 ° and more preferably about 180 °.
El mecanismo de embrague puede comprender un cuerpo de embrague que comprende una cavidad interna con una cavidad intermedia comunicada con un primer paso lateral cilindrico, un segundo paso lateral cilindrico, y un paso de acceso a la cavidad intermedia entre los pasos laterales cilindricos,- un primer casquillo giratoriamente alojado en el primer paso lateral, y un segundo casquillo giratoriamente alojado en el segundo paso lateral, emergiendo cada casquillo por uno de sus extremos a la cavidad intermedia. En este caso, la primera parte extrema del primer eje giratorio está acoplada en el primer casquillo y la primera parte extrema del segundo eje giratorio está acoplada en el segundo casquillo, mientras que el alojamiento interno para la primera parte extrema del segundo eje giratorio está formado en el interior del segundo casquillo.The clutch mechanism may comprise a clutch body comprising an internal cavity with an intermediate cavity communicated with a first cylindrical lateral passage, a second cylindrical lateral passage, and an access passage to the intermediate cavity between the cylindrical lateral passages, - a first bushing rotatably housed in the first lateral passage, and a second bushing rotatably housed in the second lateral passage, each bushing emerging from one of its ends to the intermediate cavity. In this case, the first end part of the first rotating shaft is coupled in the first bushing and the first end part of the second rotating shaft is engaged in the second bushing, while the internal housing for the first end part of the second rotating shaft is formed inside the second bushing.
Asimismo, los extremos de los caequillos que emergen a la cavidad intermedia pueden presentar sendos medios de engranaje que engranan con medios de accionamiento complementarios del mecanismo de accionamiento, como pueden ser un eje de accionamiento helicoidal que penetra por el paso de acceso a la cavidad intermedia del cuerpo de embrague, o una rueda dentada que engrana con los medios de engranaje -de cada casquillo.Likewise, the ends of the bushings that emerge into the intermediate cavity can have two gear means that engage with complementary drive means of the drive mechanism, such as a helical drive shaft that penetrates through the access passage to the intermediate cavity of the clutch body, or a cogwheel that meshes with the gear means - of each bush.
Cuando la primera parte extrema del primer eje puede girar dentro del mecanismo de embrague, éste puede comprender un alojamiento interno adicional que comprende un primer elemento de tope adicional y un segundo elemento de tope adicional, un paso adicional de sección vertical arqueada entre los elementos de tope adicionales, y un saliente adicional entre los topes adicionales. Este saliente adicional contacta en uno u otro de los elementos de tope adicionales dependiendo del sentido de giro de los ejes giratorios, de manera que la primera parte extrema del primer' eje giratorio queda acoplada en el alojamiento adicional del mecanismo de embrague. En este caso, el paso adicional y los elementos de tope adicionales también están dispuestos en un plano perpendicular al eje longitudinal de los ejes giratorios, siendo el paso adicional un entrante seleccionado entre un entrante exterior adicional formado en una primera parte extrema del perímetro externo del primer eje giratorio y un entrante interior adicional en una pared interna del alojamiento adicional en el que está acoplada la primera parte extrema del primer eje giratorio. En esta realización, los elementos de tope adicionales y el saliente adicional están dispuestos de tal forma que el saliente adicional contacta uno de los elementos de tope adicionales cuando los ejes giratorios giran en dicho primer sentido, y contacta el otro elemento de tope adicional cuando los ejes giratorios giran en dicho segundo sentido opuesto. A su vez, el saliente adicional puede ser un saliente interior adicional que emerge del perímetro interno del alojamiento adicional, o un saliente exterior adicional que emerge del perímetro externo de la primera parte extrema del primer eje. En este caso el alojamiento interno adicional para la primera parte extrema del primer eje giratorio puede estar formado en el interior del primer casquillo giratorio. El paso de sección vertical arqueada y el paso adicional de sección vertical arqueada pueden tener en conjunto una extensión de un arco de entre 40 y 270°, particularmente entre 160 y 200°, preferentemente entre 170 y 190°, y más preferentemente de 180° .When the first end portion of the first axle can rotate within the clutch mechanism, it may comprise an additional internal housing comprising a first additional stopper element and a second additional stopper element, an additional arcuate vertical section passage between the elements of additional stops, and an additional projection between the additional stops. This outgoing additional contact in one or other of the additional stop elements depending on the direction of rotation of the rotating shafts, so that the first end part of the first 'rotating shaft is coupled to the additional housing of the clutch mechanism. In this case, the additional passage and the additional stop elements are also arranged in a plane perpendicular to the longitudinal axis of the rotary axes, the additional step being a recess selected from an additional outer recess formed in a first end portion of the outer perimeter of the first rotating shaft and an additional inner recess in an inner wall of the additional housing in which the first end part of the first rotating shaft is coupled. In this embodiment, the additional stop elements and the additional projection are arranged such that the additional projection contacts one of the additional stop elements when the rotating shafts rotate in said first direction, and contacts the other additional stop element when the rotating shafts rotate in said second opposite direction. In turn, the additional projection may be an additional inner projection that emerges from the inner perimeter of the additional housing, or an additional outer projection that emerges from the outer perimeter of the first end portion of the first axis. In this case the additional internal housing for the first end part of the first rotating shaft may be formed inside the first rotating bushing. The arched vertical section passage and the additional arched vertical section passage may together have an extension of an arc between 40 and 270 °, particularly between 160 and 200 °, preferably between 170 and 190 °, and more preferably 180 ° .
En otras realizaciones de la invención, se prevé la incorporación de un elemento de masaje intermedio ubicado entre los discos de cada pareja de discos para conseguir un masaje más completo. Así, la invención prevé que el elemento de masaje intermedio comprenda al menos un cuerpo no perpendicular al eje giratorio durante el proceso de masaje y se acciona realizando un movimiento transversal sobre la parte posterior de la superficie a masajear.In other embodiments of the invention, the incorporation of an intermediate massage element located between the discs of each pair of discs is provided to achieve a more complete massage. Thus, the invention provides that the intermediate massage element comprises at least one body not perpendicular to the rotating axis during the massage process and is actuated by performing a transverse movement on the back of the surface to be massaged.
Esta configuración tiene la gran ventaja de que la superficie de masaje del elemento de masaje intermedio proporciona un movimiento transversal similar al proporcionado por un masajista del tipo conocido como "amasado", a diferencia del elemento de masaje intermedio descrito en el documento de Patente japonesa JP 2003-665, en el que dicho elemento de masaje intermedio provoca un movimiento ascendente-descendente de la pierna de forma que se varia la superficie masajeada por las láminas alargadas, y de manera que dicho elemento de masaje intermedio provoca un "golpeteo" suave en la parte inferior de la pierna que nada tiene que ver con el masaje de "amasado" que proporciona la presente invención.This configuration has the great advantage that the massage surface of the intermediate massage element provides a transverse movement similar to that provided by a masseur of the type known as "kneading", unlike the intermediate massage element described in Japanese JP. 2003-665, in which said intermediate massage element causes an upward-downward movement of the leg so that the surface massaged by the elongated sheets is varied, and so that said intermediate massage element causes a soft "tapping" in the lower part of the leg that has nothing to do with the "kneading" massage provided by the present invention.
En otra realización de la invención el elemento de masaje intermedio comprende un cuerpo soportado en el eje giratorio, cuya superficie de masaje es longitudinal respecto a la parte posterior de la superficie a masajear, sobre la que el movimiento transversal define aproximadamente un "ocho" . En esta realización de la invención el elemento de masaje intermedio está unido a un punto fijo mediante al menos un primer elemento elástico, para evitar que dicho elemento de masaje intermedio gire al ser accionado, manteniendo la superficie de masaje en contacto con la superficie a masajear.In another embodiment of the invention the intermediate massage element comprises a body supported on the rotating shaft, whose massage surface is longitudinal with respect to the back of the surface to be massaged, on which the transverse movement defines approximately an "eight". In this embodiment of the invention the intermediate massage element is attached to a fixed point by at least one first elastic element, to prevent said intermediate massage element from rotating when operated, keeping the massage surface in contact with the surface to be massaged. .
En otra realización de la invención se ha previsto que el elemento de masaje intermedio esté soportado en uno de los discos de la pareja de discos, en lugar de en el eje giratorio, tal y como sucedía en la realización anterior. El elemento de masaje intermedio puede estar constituido por una extensión lateral que es solidaria de uno de los discos de la pareja de discos, o por el contrario la extensión lateral puede estar soportada en uno de los discos de la pareja de discos mediante un eje que permite su giro. En estos dos últimos casos los discos de cada pareja de discos están unidos a un punto fijo mediante al menos un segundo elemento elástico para impedir su giro con el desplazamiento angular del eje giratorio y mantener la superficie de masaje del elemento de masaje intermedio en contacto con la parte a masajear.In another embodiment of the invention it is provided that the intermediate massage element is supported on one of the discs of the disc pair, instead of on the rotating shaft, as was the case in the previous embodiment. The intermediate massage element may be constituted by a lateral extension that is integral with one of the discs of the pair of discs, or on the contrary the lateral extension can be supported on one of the discs of the pair of discs by means of an axis that allows its rotation. In these last two cases the discs of each pair of discs are attached to a fixed point by at least a second elastic element to prevent its rotation with the angular displacement of the rotating shaft and keep the massage surface of the intermediate massage element in contact with The part to massage.
Para el caso en el que el elemento de masaje intermedio esté soportado en uno de los discos, la invención prevé que dicho elemento de masaje intermedio comprenda un^ cuerpo cuya superficie de masaje es alargada y longitudinal respecto a la superficie a masajear, y del tipo de la descrita para el caso en el que el elemento de masaje intermedio esté soportado en el eje giratorio. También cabe la posibilidad de que el elemento de masaje intermedio comprenda un cuerpo alargado inclinado hacia el eje giratorio, cuya superficie de masaje se corresponde con una de sus zonas extremas.In the case where the intermediate massage element is supported on one of the discs, the invention provides that said intermediate massage element comprises a body whose massage surface is elongated and longitudinal with respect to the surface to be massaged, and of the type of that described for the case in which the intermediate massage element is supported on the rotating shaft. It is also possible that the intermediate massage element comprises an elongated body inclined towards the rotating axis, whose massage surface corresponds to one of its extreme areas.
En el caso en el que las extensiones laterales, que constituyen el elemento de masaje intermedio, estén fijadas al disco mediante un eje que permite su giro, se prevé que esta unión se efectúe mediante un tercer elemento elástico para mantener la superficie de masaje en contacto con la parte a masajear.In the case where the lateral extensions, which constitute the intermediate massage element, are fixed to the disc by means of an axis that allows its rotation, it is envisaged that this union is made by a third elastic element to keep the massage surface in contact. With the part to massage.
Adicionalmente,, el cuerpo alargado inclinado dirigido hacia el eje giratorio hace tope en un pivote solidario de uno de los discos. Este tope está previsto para que mediante la acción del tercer elemento elástico, se mantenga el cuerpo alargado en contacto con dicho tope.Additionally, the elongated inclined body directed towards the rotating shaft abuts a pivot integral to one of the discs. This stop is provided so that by the action of the third elastic element, the elongated body is kept in contact with said stop.
La invención prevé que en cada uno de los discos que constituyen la pareja de discos, incluya una extensión lateral solidaria a dichos discos, de manera que estas extensiones pueden ser idénticas o diferentes según los distintos tipos de extensiones descritas anteriormente.The invention provides that in each of the discs that constitute the pair of discs, it includes a lateral extension integral with said discs, so that these extensions can be identical or different according to the different types of extensions described above.
Para el caso en el que el elemento de masaje intermedio comprenda un cuerpo alargado inclinado hacia el eje giratorio, el movimiento que efectúa el cuerpo alargado, es un movimiento aproximadamente circular.In the case where the intermediate massage element comprises an elongated body inclined towards the rotating axis, the movement made by the elongated body is an approximately circular movement.
La superficie de masaje del elemento de masaje intermedio en todas las realizaciones anteriores es al menos semicilíndrica .The massage surface of the intermediate massage element in all the above embodiments is at least semi-cylindrical.
Otra posible realización de la invención prevé que el elemento de masaje intermedio esté determinado por una pletina que incluye medios de vibración para aplicarle un movimiento vibratorio y proporcionar un masaje de estas características a la pierna del usuario.Another possible embodiment of the invention provides that the intermediate massage element is determined by a plate that includes vibration means to apply a vibratory motion and provide a massage of these characteristics to the user's leg.
En este caso la pletina se sujeta al bastidor del mecanismo o sobre uno o ambos discos de cada pareja de discos .In this case the plate is attached to the frame of the mechanism or on one or both discs of each pair of discs.
En la realización preferente de la invención la pletina se sujeta al bastidor por uno de sus extremos, quedando el otro extremo libre para facilitar la vibración. Los medios de vibración comprenden un motor de dos ejes opuestos dotados en sus extremos de un contrapeso, todo ello de manera que el motor queda alojado en una carcasa fijada sobre la cara inferior de la pletina para que al activarse el motor se produzca la vibración de la misma. Por otro lado, la invención incorpora medios para regular la separación entre los discos de las parejas de discos, medios que permiten el desplazamiento axial de al menos uno de dichos discos de cada pareja de discos sobre el eje giratorio. Estos medios están preferentemente constituidos por un cuarto elemento elástico que mantiene al menos a uno de los discos de cada pareja de discos presionando contra un tope, de manera que el al menos disco de cada pareja de discos se desplaza venciendo la acción del cuarto elemento elástico, al ubicar una superficie de masaje con dimensiones superiores a la separación prevista entre los discos de cada pareja de discos.In the preferred embodiment of the invention, the plate is attached to the frame by one of its ends, the other end being free to facilitate vibration. The vibration means comprise a motor of two opposite axes provided at its ends with a counterweight, all in such a way that the motor is housed in a housing fixed on the underside of the plate so that when the motor is activated the vibration of the motor occurs. the same. On the other hand, the invention incorporates means for regulating the separation between the discs of the disc pairs, means which allow the axial displacement of at least one of said discs of each pair of discs on the rotating axis. These means are preferably constituted by a fourth elastic element that keeps at least one of the discs of each pair of discs pressing against a stop, so that the at least disc of each pair of discs moves overcoming the action of the fourth elastic element , by locating a massage surface with dimensions greater than the expected separation between the discs of each pair of discs.

Las figuras 1 y 2 muestran una primera realización del mecanismo de masaje según la presente invención que comprende una primera pareja de discos la, Ib de masaje, que son discos giratorios y están unidos fija y excéntricamente a un primer eje giratorio A, a una distancia entre sí para masajear lados opuestos de la parte inferior de una primera pierna 3a del usuario, así como una segunda pareja de discos 2a, 2b de masaje, que también son discos giratorios y están unidos fija y excéntricamente a un segundo eje giratorio B, a una distancia entre sí para masajear lados opuestos de la parte inferior de una segunda pierna 3b del usuario. Los discos giratorios la, Ib de la primera pareja de discos están dispuestos en primeros planos de rotación inclinados con respecto al primer eje giratorio A, mientras que los discos giratorios 2a, 2b de la segunda pareja de discos están dispuestos en segundos planos de rotación inclinados con respecto al segundo eje giratorio B.Figures 1 and 2 show a first embodiment of the massage mechanism according to the present invention comprising a first pair of massage discs, Ib, which are rotating discs and are fixedly and eccentrically attached to a first rotating axis A, at a distance each other to massage opposite sides of the lower part of a user's first leg 3a, as well as a second pair of massage discs 2a, 2b, which are also rotating discs and are fixedly and eccentrically attached to a second rotating axis B, a a distance from each other to massage opposite sides of the bottom of a second leg 3b of the user. The rotating discs la, Ib of the first pair of discs are arranged in inclined rotation planes with respect to the first rotating axis A, while the rotating discs 2a, 2b of the second pair of discs are arranged in second inclined planes of rotation with respect to the second rotating axis B.
Los ejes giratorios A, B están conectados por sus respectivos primeros extremos A-I, B-I a un mecanismo de embrague 5 que acopla dichos ejes A, B entre sí. El primer eje A está acoplado por su segundo extremo A-2 a un rodamiento, mientras que el segundo extremo B-2 del segundo eje está conectado, de manera en sí convencional, a un mecanismo de accionamiento 4 convencional, tal como a un motor eléctrico con un grupo reductor, capaz de conferir una rotación a los ejes giratorios A, B en sentido de giro contrario a las agujas del reloj (fig. 1), y sentido de giro de las agujas del reloj (fig.2) . El mecanismo de embrague acopla los ejes A, B de tal forma que, cuando los ejes giran en el sentido contrario las agujas del reloj como se muestra en la figura 1, las parejas de discos de masaje la, Ib; 2a, 2b quedan alineadas en sus respectivos ejes A, B en posiciones inclinadas idénticas, de manera que, aprietan y liberan simultáneamente las mismas partes de las piernas 3a, 3b del usuario, mientras que, cuando los ejes A, B giran en el sentido de las agujas del reloj (fig. 2) , el mecanismo de embrague 5 provoca que el primer eje A queda desfasado, en cuanto al giro, en aproximadamente 180° respecto del segundo eje B. Al producirse este desfase, los segundos discos rotatorios 2a, 2b adoptan una posición en la que sus inclinaciones respecto del segundo eje giratorio B son justamente las contrarias a las inclinaciones de los primeros discos de masaje la, Ib de manera que, cuando los primeros discos de masaje la, Ib aprietan una primera parte y liberan otra parte de la primera pierna 3a del usuario, los segundos discos de masaje 2a, 2b liberan la primera parte correspondiente en la segunda pierna 3b y aprietan la segunda parte correspondiente de esa segunda pierna 3b.The rotating shafts A, B are connected by their respective first ends AI, BI to a clutch mechanism 5 that couples said shafts A, B to each other. The first axis A is coupled by its second end A-2 to a bearing, while the second end B-2 of the second axis is connected, in a conventional manner, to a conventional drive mechanism 4, such as a motor electric with a reduction group, capable of conferring a rotation to the rotating shafts A, B in a counterclockwise direction (fig. 1), and clockwise rotation (fig. 2). The clutch mechanism couples the axes A, B such that, when the axes rotate counterclockwise as shown in figure 1, the pairs of massage discs la, Ib; 2a, 2b are aligned in their respective axes A, B in identical inclined positions, so that they simultaneously squeeze and release them parts of the user's legs 3a, 3b, while, when the axes A, B rotate clockwise (fig. 2), the clutch mechanism 5 causes the first axis A to become outdated, as soon as at rotation, at approximately 180 ° with respect to the second axis B. When this offset occurs, the second rotary disks 2a, 2b adopt a position in which their inclinations with respect to the second rotary axis B are just the opposite of the inclinations of the first discs massage the, Ib so that, when the first massage discs the, Ib press a first part and release another part of the user's first leg 3a, the second massage discs 2a, 2b release the corresponding first part in the second leg 3b and press the corresponding second part of that second leg 3b.
Las figuras 3 a 8 muestran una primera realización de un mecanismo de embrague 5 que puede integrarse en el mecanismo de masaje de las figuras 1 y 2. Este mecanismo 5 comprende un cuerpo 5a con un alojamiento 10 en el que está acoplado el extremo A-I del primer eje giratorio A, y otro alojamiento 6, formado en alineación axial con el alojamiento 10, en el que está acoplado el segundo eje giratorio B. El cuerpo 5a está alojado en un casquillo exterior 11. El alojamiento interno 6 comprende un primer elemento de tope 6a y un segundo elemento de tope 6b, un paso 6c de sección vertical arqueada entre los elementos de tope 6a, 6b, y un saliente 6d en forma de nervio axial que se desplaza por dicho paso 6c entre los topes 6a, 6b en dependencia del sentido de giro de los ejes A, B. A su vez, el paso 6c y los elementos de tope 6a, 6b están dispuestos en un plano perpendicular al eje longitudinal de los ejes giratorios A, B. En la realización mostrada, el paso 6c está formado por un entrante interior en una parte de una pared interna del alojamiento 6 en el que está acoplado la parte extrema B-I del segundo eje giratorio B y se desplaza en el entrante interior o paso 6c. El alojamiento 10 comprende un entrante en el que se aloja un saliente 1Od que emerge de la periferia del primer extremo A-I del primer eje A, de manera que el primer eje A queda inmovilizado en el cuerpo 5a del mecanismo de embrague 5. Las figuras 3 a 5 muestran la disposición del entrante 6d en el paso 6c cuando los ejes A, B giran en sentido contrario al reloj, es decir, en la posición correspondiente a la figura 1. En esta situación, el saliente 6d topa contra el primer elemento de tope 6a, al girar los ejes A, B, y los respectivos discos de masaje la, Ib; 2a, 2b quedan en la posición mostrada en la figura 1. Como puede verse en la figura 6, cuando cambia el sentido de giro de los ejes A, B, el saliente 6d se va desplazando por el paso 6c en el sentido de las agujas del reloj hasta llegar a la posición que muestran las figuras 7 y 8, topando contra el segundo elemento de tope 6b de forma que se produce el desfase más arriba mencionado de aproximadamente 180° entre los ejes A, B y los discos de masaje 2a, 2b acoplados en el segundo eje adoptan la posición mostrada en la figura 2. La realización del mecanismo de embrague 5 mostrada en las figuras 9 a 14 se diferencia de la realización de las figuras 3 a 8 en que el paso 6c es un entrante exterior formado en el perímetro externo de la primera parte extrema B-I del segundo eje giratorio B y el saliente 6d es un saliente interior que emerge del perímetro interno del alojamiento 6, y que el primer eje A queda inmovilizado en el cuerpo 5a del mecanismo de embrague 5 mediante un saliente que emerge de la pared interior del alojamiento 10 que encaja en un entrante complementario en la primera parte extrema A-I del primer eje A. En la posición de los discos de masaje la, Ib; 2a, 2b mostrada en la figura 1, es decir, cuando los ejes giratorios A, B giran en sentido contrario a las agujas del reloj , el saliente 6d topa contra el primer elemento de tope 6a tal y como muestran las figuras 9 a 11. Cuando cambia el sentido de giro de los ejes A, B, el saliente 6d deja de estar en contacto con el elemento de tope 6a en el primer extremo A-I del eje giratorio A pasando por la posición mostrada en la figura 12 hasta la posición mostrada en las figuras 13 y 14, en las que el segundo elemento de tope 6b contacta con el saliente 6d, produciéndose entonces también el mencionado desfase de aproximadamente 180° entre los ejes giratorios A, B con lo que los discos de masaje 2a, 2b cambian su posición como muestra la figura 2.Figures 3 to 8 show a first embodiment of a clutch mechanism 5 that can be integrated into the massage mechanism of Figures 1 and 2. This mechanism 5 comprises a body 5a with a housing 10 in which the AI end of the first rotating shaft A, and another housing 6, formed in axial alignment with the housing 10, in which the second rotating shaft B is coupled. The body 5a is housed in an outer sleeve 11. The internal housing 6 comprises a first element of stop 6a and a second stop element 6b, a passage 6c of arcuate vertical section between the stop elements 6a, 6b, and an axial rib-shaped projection 6d that travels through said passage 6c between the stops 6a, 6b in dependence of the direction of rotation of the axes A, B. In turn, the passage 6c and the stop elements 6a, 6b are arranged in a plane perpendicular to the longitudinal axis of the rotating axes A, B. In the embodiment shown, the step 6c is formed by an ent Inner part in a part of an inner wall of the housing 6 in which the end part BI of the second rotating shaft B is coupled and moves in the inner recess or step 6c. The accommodation 10 it comprises a recess in which a projection 1Od is housed that emerges from the periphery of the first end AI of the first axis A, so that the first axis A is immobilized in the body 5a of the clutch mechanism 5. Figures 3 to 5 show the arrangement of the recess 6d in step 6c when the axes A, B rotate counterclockwise, that is, in the position corresponding to figure 1. In this situation, the projection 6d bumps against the first stop element 6a, turning the axes A, B, and the respective massage discs la, Ib; 2a, 2b remain in the position shown in figure 1. As can be seen in figure 6, when the direction of rotation of axes A, B changes, the projection 6d moves through step 6c in the direction of the needles of the watch until reaching the position shown in Figures 7 and 8, bumping against the second stop element 6b so that the above mentioned offset of approximately 180 ° occurs between the axes A, B and the massage discs 2a, 2b coupled on the second shaft adopt the position shown in Figure 2. The embodiment of the clutch mechanism 5 shown in Figures 9 to 14 differs from the embodiment of Figures 3 to 8 in that step 6c is an outer recess formed at the outer perimeter of the first end part BI of the second rotating axis B and the projection 6d is an inner projection that emerges from the internal perimeter of the housing 6, and that the first axis A is immobilized in the body 5a of the clutch mechanism 5 by a ledge which emerges from the inner wall of the housing 10 which fits into a complementary recess in the first end portion AI of the first axis A. In the position of the massage discs la, Ib; 2a, 2b shown in figure 1, that is, when the rotating shafts A, B rotate counterclockwise, the projection 6d bumps against the first stopper element 6a as shown in figures 9 to 11. When the direction of rotation of axes A, B changes, the projection 6d stops being in contact with the stop element 6a at the first end AI of the rotating shaft A passing through the position shown in figure 12 to the position shown in figures 13 and 14, in which the second stop element 6b contacts the projection 6d, then also producing the aforementioned offset of approximately 180 ° between the rotating shafts A, B whereby the massage disks 2a, 2b change their position as shown in Figure 2.
En la realización del mecanismo de masaje mostrada en las figuras 15 y 16, el mecanismo de accionamiento 4 está conectado al mecanismo de embrague 5, siendo por lo demás el funcionamiento de este mecanismo análogo al de la realización del mecanismo de las figuras 1 y 2.In the embodiment of the massage mechanism shown in Figures 15 and 16, the drive mechanism 4 is connected to the clutch mechanism 5, the operation of this mechanism being similar to that of the mechanism of Figures 1 and 2 .
Las figuras 17 a 20 muestran una realización de un mecanismo de embrague 5 que puede incorporarse en el mecanismo de masaje de las figuras 15 y 16. En esta realización, el mecanismo de embrague 5 comprende un cuerpo de embrague 5a con una cavidad interna 5b la cual comprende una cavidad intermedia 5c que está comunicada con un primer paso lateral 5d cilindrico, con un segundo paso lateral 5e cilindrico, y con un paso de acceso 5f a la cavidad intermedia 5c. El paso de acceso 5f se encuentra entre dichos pasos laterales cilindricos 5d, 5e. En el primer paso lateral 5d está giratoriamente alojado un primer casquillo 7, en el que está acoplada la primera parte extrema A-I del primer eje giratorio A. En el segundo paso lateral 5e está giratoriamente alojado un segundo casquillo 8. en el que está acoplada la primera parte extrema B-I del segundo eje giratorio B. Los casquillos 7, 8 penetran por uno de sus extremos a la cavidad intermedia 5c. Estos extremos están provistos de sendas pestañas periféricas 7b, 8b provistas de sendos engranajes 7a, 8a que engranan con una rueda dentada 9 conectada mediante un eje propulsor 9a al mecanismo de accionamiento 4 que puede ser, por ejemplo, una unidad de motor eléctrico con reductora en sí convencional. El eje 9a penetra a la cavidad intermedia 5c a través del paso de acceso 5f.Figures 17 to 20 show an embodiment of a clutch mechanism 5 that can be incorporated into the massage mechanism of Figures 15 and 16. In this embodiment, the clutch mechanism 5 comprises a clutch body 5a with an internal cavity 5b the which comprises an intermediate cavity 5c which is communicated with a first lateral passage 5d cylindrical, with a second lateral passage 5e cylindrical, and with an access passage 5f to the intermediate cavity 5c. The access passage 5f is between said cylindrical lateral passages 5d, 5e. In the first lateral passage 5d a first bushing 7 is rotatably housed, in which the first end portion AI of the first rotating shaft A is coupled. In the second lateral passage 5e a second bushing 8 is rotatably housed in which the first end part BI of the second rotating shaft B. The bushings 7, 8 penetrate one of its ends into the intermediate cavity 5c. These ends are provided with peripheral flanges 7b, 8b provided with two gears 7a, 8a that engage with a cogwheel 9 connected by a propeller shaft 9a to the drive mechanism 4 which can be, for example, an electric motor unit with reducer Conventional itself. Axis 9a it penetrates the intermediate cavity 5c through the access passage 5f.
En el interior del primer casquillo 7 está formado un alojamiento interno 10 en el que está inmovilizada la primera parte extrema A-I del eje giratorio A mediante un saliente 10, en forma de nervio radial, que emerge de dicha primera parte extrema A-I y encaja en un entrante complementario en la pared interior de alojamiento 10.Inside the first bushing 7 an internal housing 10 is formed in which the first end part AI of the rotating shaft A is immobilized by a projection 10, in the form of a radial rib, which emerges from said first end part AI and fits into a complementary inlet in the inner wall of housing 10.
En el interior del segundo casquillo 8 está formado un alojamiento interno 6 de características análogas a las del alojamiento 6 en el cuerpo 5a del mecanismo de embrague mostrado en las figuras 3 a 8. Así, el alojamiento interno 6 comprende un primer elemento de tope 6a y un segundo elemento de tope 6b, un paso 6c de sección vertical arqueada de unos 180° entre los elementos de tope 6a, 6b, y un saliente 6d en forma de nervio radial entre los topes 6a, 6b en dependencia del sentido de giro de los ejes A, B. A su vez, el paso 6c y los elementos de tope 6a, 6b están dispuestos en un plano perpendicular al eje longitudinal de los ejes giratorios A, B. El paso 6c está formado por un entrante interior en una parte de una pared interna del alojamiento 6, mientras que el saliente 6d emerge del perímetro externo de dicha primera parte extrema B-I y se desplaza en el entrante interior 6c.Inside the second bushing 8 there is formed an internal housing 6 of similar characteristics to those of the housing 6 in the body 5a of the clutch mechanism shown in Figures 3 to 8. Thus, the internal housing 6 comprises a first stop element 6a and a second stop element 6b, a passage 6c of arcuate vertical section of about 180 ° between the stop elements 6a, 6b, and a radial rib-shaped projection 6d between the stops 6a, 6b depending on the direction of rotation of the axes A, B. In turn, the passage 6c and the stop elements 6a, 6b are arranged in a plane perpendicular to the longitudinal axis of the rotating axes A, B. The passage 6c is formed by an interior recess in one part of an inner wall of the housing 6, while the projection 6d emerges from the outer perimeter of said first end part BI and moves in the inner recess 6c.
El funcionamiento del mecanismo de embrague mostrado en las figuras 17 a 20 es análogo al del mecanismo de embrague de las figuras 3 a 8, a excepción de que los medios de accionamiento 4 no están directamente conectados a uno de los ejes giratorios A, B, sino que hacen girar unos caequillos 7, 8 que a su vez arrastran a los ejes giratorios A, B en su movimiento de rotación. Así cuando los casquillos 7, 8 giran en el sentido de las agujas del reloj, el elemento de tope 6b en el alojamiento 6 contacta con el saliente radial 6d que emerge de la primera parte B-I del segundo eje giratorio B de manera que ese eje B gira conjuntamente con el casquillo 8 en el mismo sentido, quedando entonces dispuestos los discos de masaje la, Ib; 2a, 2b en las posiciones mostradas en la figura 15. Por otra parte, cuando los caequillos 7, 8 empiezan a girar en sentido contrario a las agujas del reloj, el saliente 6d.deja de hacer tope con el elemento de tope 6b, y después de aproximadamente media vuelta del casguillo 8, contacta con el elemento de tope 6a de manera que el eje B empieza a girar en el mismo sentido que el casquillo 8. Debido al desfase de aproximadamente 180° que entonces se ha producido entre los ejes A, B, los discos de masaje 2a, 2b adoptan la posición mostrada en la figura 16.The operation of the clutch mechanism shown in Figures 17 to 20 is analogous to that of the clutch mechanism of Figures 3 to 8, except that the drive means 4 are not directly connected to one of the rotating shafts A, B, instead, they rotate a little rod 7, 8 which in turn drag the rotating axes A, B in their rotational movement. Thus, when the bushes 7, 8 rotate clockwise, the stop element 6b in the housing 6 contacts the radial projection 6d that emerges from the first part BI of the second rotating axis B so that axis B rotates together with the bushing 8 in the same direction, then the disks of massage la, Ib; 2a, 2b in the positions shown in Figure 15. On the other hand, when the bushes 7, 8 begin to rotate counterclockwise, the projection 6d. Stops making a stop with the stopper element 6b, and after about half a turn of the bushing 8, contact the stopper element 6a so that the B axis begins to rotate in the same direction as the bushing 8. Due to the approximately 180 ° offset that has then occurred between the A axes , B, the massage discs 2a, 2b adopt the position shown in Figure 16.
Las figuras 20 a 23 muestran otra realización de un mecanismo de embrague 5 que puede incorporarse en el mecanismo de masaje de las figuras 15 y 16. Esta realización se diferencia de la realización de las figuras 17 a 20 en que el paso 6c se extiende en 90° en vez de en 180° en la pared interna del alojamiento 6 del segundo casquillo 8, y en que el alojamiento interno 10 en el primer casquillo tiene una configuración análoga al alojamiento interno 6 en el segundo casquillo 8. Así, el alojamiento interno adicional 10 comprende un primer elemento de tope adicional 10a y un segundo elemento de tope adicional 10b, un paso adicional 10c de sección vertical arqueada de una extensión de aproximadamente 90° entre dichos elementos de tope adicionales 10a, 10b, y un saliente adicional 1Od entre dichos topes adicionales 10a, 10b en dependencia del sentido de giro de los ejes giratorios A, B. El paso adicional 10c y los elementos de tope adicionales 10a, 10b están dispuestos en un plano perpendicular al eje longitudinal de los ejes giratorios A, B, siendo el paso adicional 10c un entrante interior en una pared interna del alojamiento adicional 10 en el que está acoplado dicha primera parte extrema A-I del primer eje giratorio A, mientras que el saliente adicional 1Od emerge del perímetro externo de la primera parte extrema A-I del primer eje giratorio A. Cuando los casquillos 7, 8 giran en el sentido de las agujas del reloj, el elemento de tope 6b en el alojamiento 6 contacta el saliente radial 6d que emerge de la primera parte B-I del segundo eje giratorio B de manera que ese eje B gira conjuntamente con el casquillo 8 en el mismo sentido. A su vez, en el alojamiento interno 10 del primer casquillo 7, el saliente 1Od contacta el tope 10a, de forma que el eje A gira conjuntamente con el casquillo 7 en el mismo sentido. En esta situación, los discos de masaje la, Ib; 2a, 2b quedan dispuestos en las posiciones mostradas en la figura 15. Cuando los caequillos 7, 8 empiezan a girar en sentido contrario a las agujas del reloj, en el primer casquillo 7 el saliente 1Od deja de hacer tope con el elemento de tope 10a, y después de aproximadamente un cuarto de vuelta del casquillo I1 contacta con el segundo elemento de tope 10b de manera que el eje A empieza a girar en el mismo sentido que el casquillo 7. Simultáneamente en el segundo casquillo 8 el saliente 6d deja de hacer tope con el elemento de tope 6b, y también después de aproximadamente un cuarto de vuelta del casquillo 8, contacta con el elemento de tope 6a de manera que el eje B empieza a girar en el mismo sentido que el casquillo 8. Debido al desfase conjunto de aproximadamente 180° que entonces se ha producido entre los ejes A, B, los discos de masaje la, Ib; 2a, 2b adoptan la posición mostrada en la figura 16. En las figuras 24 a 33 se muestran diferentes realizaciones en las que se incorpora un elemento de masaje intermedio tal y como a continuación se describe. Estas realizaciones se han dibujado en mayor detalle que las anteriores y no especifican el mecanismo de embrague para facilitar la comprensión del elemento de masaje intermedio.Figures 20 to 23 show another embodiment of a clutch mechanism 5 that can be incorporated in the massage mechanism of Figures 15 and 16. This embodiment differs from the embodiment of Figures 17 to 20 in that step 6c extends in 90 ° instead of 180 ° in the inner wall of the housing 6 of the second bushing 8, and in that the internal housing 10 in the first bushing has a configuration analogous to the internal housing 6 in the second bushing 8. Thus, the internal housing additional 10 comprises a first additional stop element 10a and a second additional stop element 10b, an additional passage 10c of arcuate vertical section of an extension of approximately 90 ° between said additional stop elements 10a, 10b, and an additional projection 1Od between said additional stops 10a, 10b depending on the direction of rotation of the rotating shafts A, B. The additional passage 10c and the additional stop elements 10a, 10b are arranged in a plan or perpendicular to the longitudinal axis of the rotating axes A, B, the additional passage 10c being an interior recess in an internal wall of the additional housing 10 in which said first end portion AI of the first rotary axis A is coupled, while the additional projection 1Od emerges from the outer perimeter of the first end part AI of the first rotating shaft A. When the bushes 7, 8 rotate in the direction of the clockwise, the stopper element 6b in the housing 6 contacts the radial projection 6d emerging from the first part BI of the second rotating shaft B so that that axis B rotates together with the bushing 8 in the same direction. In turn, in the internal housing 10 of the first bushing 7, the projection 1Od contacts the stop 10a, so that the axis A rotates together with the bushing 7 in the same direction. In this situation, the massage discs la, Ib; 2a, 2b are arranged in the positions shown in Figure 15. When the bushes 7, 8 begin to rotate counterclockwise, in the first socket 7 the projection 1Od stops abutting with the stopper element 10a , and after approximately a quarter turn of the bushing I 1 contacts the second stop element 10b so that the axis A begins to rotate in the same direction as the bushing 7. Simultaneously in the second bushing 8 the projection 6d stops stop with the stop element 6b, and also after about a quarter turn of the bushing 8, contact the stop element 6a so that the axis B starts to rotate in the same direction as the bushing 8. Due to the offset set of approximately 180 ° which has then occurred between the axes A, B, the massage discs la, Ib; 2a, 2b adopt the position shown in Figure 16. Figures 24 to 33 show different embodiments in which an intermediate massage element is incorporated as described below. These embodiments have been drawn in greater detail than the previous ones and do not specify the clutch mechanism to facilitate the understanding of the intermediate massage element.
En estos casos el mecanismo está soportado en un bastidor 12 en el que se fija, con posibilidad de giro el primer eje giratorio A, y el segundo eje giratorio B, que son movidos mediante un motor 4. En los ejes giratorios A, B se montan las parejas de discos Ia, Ib; 2a, 2b mediante una excéntrica 14 de manera que están soportados en un plano inclinado en dirección longitudinal hacia lados opuestos y se mueven cambiando el grado de inclinación con respecto a la longitud de la pierna, la cual se ubica sobre los discos la, Ib; 2a, 2b para masajearla.In these cases, the mechanism is supported on a frame 12 in which the first rotary axis A, and the second rotary axis B, which are moved by means of a motor 4, are fixed. With rotational axes A, B, ride the couples of disks Ia, Ib; 2a, 2b by an eccentric 14 so that they are supported in an inclined plane in a longitudinal direction towards opposite sides and move by changing the degree of inclination with respect to the length of the leg, which is located on the disks la, Ib; 2a, 2b to massage it.
Los diferentes elementos de masaje intermedio pueden ubicarse indistintamente entre los primeros discos la, Ib o entre los segundos discos 2a, 2b y ser iguales o diferentes. En las figuras se han representado los distintos elementos de masaje intermedio según diferentes realizaciones, pero según ha sido comentado éstas pueden ser las mismas para cada uno de los discos de cada pareja de discos.The different elements of intermediate massage can be located interchangeably between the first discs la, Ib or between the second discs 2a, 2b and be the same or different. In the figures the different elements of intermediate massage have been represented according to different embodiments, but as mentioned they can be the same for each of the discs of each pair of discs.
Así, entre, por ejemplo, los segundos discos 2a, 2b de masaje se ubica un elemento de masaje intermedio 15 que también está montado mediante una excéntrica 14 en el segundo eje giratorio B, y que igualmente cambia el grado de inclinación respecto a la longitud de la pierna 3b, y que está rematado superiormente mediante una superficie cilindrica 16 en la que apoya longitudinalmente la pierna 3b del usuario, de forma que al accionarse el eje giratorio B se produce un movimiento transversal de la superficie cilindrica 16 respecto a la longitud de la pierna 3b definiendo aproximadamente un "ocho", lo que provoca una sensación de masaje muy parecida al masaje de "amasamiento" proporcionado por un masajista.Thus, between, for example, the second massage discs 2a, 2b is located an intermediate massage element 15 which is also mounted by means of an eccentric 14 on the second rotating axis B, and which also changes the degree of inclination with respect to the length of the leg 3b, and which is topped off by a cylindrical surface 16 on which the user's leg 3b is longitudinally supported, so that when the rotary axis B is operated, a transverse movement of the cylindrical surface 16 with respect to the length of leg 3b defining approximately an "eight", which causes a sensation of massage very similar to the "kneading" massage provided by a masseuse.
Para mantener en contacto la superficie cilindrica 16 con la parte inferior de la pierna, el elemento intermedio 15 está sujeto al bastidor mediante un primer elemento elástico constituido por un primer resorte 24. De esta forma se impide que al girar el eje giratorio B gire el elemento de masaje intermedio 15 consiguiéndose el efecto indicado.In order to keep the cylindrical surface 16 in contact with the lower part of the leg, the intermediate element 15 is attached to the frame by means of a first elastic element constituted by a first spring 24. In this way it is prevented that by rotating the rotating axis B rotates intermediate massage element 15 achieving the indicated effect.
Otra de las posibles realizaciones de la invención prevé que el elemento de masaje intermedio, en lugar de estar previsto en uno de los ejes giratorios A, B, esté soportado en uno de los discos, por ejemplo en los discos la, Ib, a los que se une mediante un eje 20 sobre el que puede girar. En el ejemplo de realización se prevé que cada uno de los discos la, Ib soporten un elemento intermedio de masaje. Así sobre uno de los discos Ib, comprende una extensión lateral dotada de un primer cuerpo 18 que comprende un cuerpo alargado cilindrico 19 e inclinado hacia el primer eje giratorio A.Another of the possible embodiments of the invention provides that the intermediate massage element, instead of being provided on one of the rotating shafts A, B, is supported in one of the discs, for example in discs la, Ib, to which it is attached by means of an axis 20 on which it can rotate. In the exemplary embodiment, it is envisioned that each of the disks la, Ib support an intermediate massage element. Thus, on one of the disks Ib, it comprises a lateral extension provided with a first body 18 comprising an elongated cylindrical body 19 and inclined towards the first rotating axis A.
En el otro disco la de la primera pareja de discos, se ha previsto una extensión lateral que incluye un segundo cuerpo 21 que comprende un cuerpo alargado semicilíndrico 22 inclinado hacia el eje A. Para estos casos es necesario que los discos la, Ib no giren junto con el ej¿e A, para lo que se fijan al bastidor 12 mediante dos segundos resortes 17 opuestos que impiden el giro de los discos la, Ib, manteniéndose el primer cuerpo 18 y segundo cuerpo 21 en la posición requerida. Además estos cuerpos 18 y 21 también se encuentran sujetos mediante un tercer resorte 23 a cada uno de los discos la, Ib y complementariamente, éstos cuentan con un pivote 25 en el que hacen tope los cuerpos 18 y 21 que por la acción del tercer resorte 23 se mantienen en contacto con dichos pivotes 25, para mantenerlos en la posición de masaje, y no permitir que giren sobre el eje 20. El cuerpo 18 comprende un cuerpo alargado cilindrico 19 y el cuerpo 21 un cuerpo alargado semicilíndrico 22, en los que apoya la pierna a masajear.In the other disc that of the first pair of discs, a lateral extension is provided that includes a second body 21 comprising an elongated semi-cylindrical body 22 inclined towards the axis A. For these cases it is necessary that the disks la, Ib do not rotate together with ej ¿ e A, for which they are fixed to the frame 12 by means of two opposite second springs 17 that prevent the rotation of the disks la, Ib, keeping the first body 18 and second body 21 in the required position. In addition, these bodies 18 and 21 are also attached by means of a third spring 23 to each of the discs LA, Ib and, in addition, they have a pivot 25 in which the bodies 18 and 21 stop, which by the action of the third spring 23 remain in contact with said pivots 25, to keep them in the massage position, and not allow them to rotate on the axis 20. The body 18 comprises an elongated cylindrical body 19 and the body 21 an elongated semi-cylindrical body 22, in which Support the leg to massage.
Esta configuración determina que al girar el eje giratorio A y producirse el movimiento de los discos la, Ib en el que modifican su inclinación respecto al primer eje giratorio A, aproximándose y alejándose secuencialmente entre sí por su disposición sobre la excéntrica 14, provoca el mismo desplazamiento de los cuerpos 19 y 22 cuyas superficies de masaje realizan un movimiento circular transversal sobre la parte posterior de la pierna y en el espacio comprendido entre los discos la, Ib, mejorándose el efecto de masaje según se muestra en las figuras 27 a 30. En el movimiento de los discos la, Ib, los cuerpos 18 y 21 no deben tocarse, sino que han de mantener una distancia de seguridad entre ellos para evitar pellizcos en la zona masajeada. De esta manera se provoca el masaje deseado tal y como fue descrito. Las dimensiones de los cuerpos 18 y 21 y los pivotes 25 ayudan a mantener dicha distancia de seguridad.This configuration determines that turning the rotating axis A and the movement of the disks la, Ib, in which they modify their inclination with respect to the first rotating axis A, approaching and sequentially moving away from each other by their arrangement on the eccentric 14, causes the same displacement of bodies 19 and 22 whose massage surfaces perform a circular transverse movement on the back of the leg and in the space between the disks la, Ib, the massage effect being improved as shown in figures 27 to 30. In the movement of the la, Ib discs, bodies 18 and 21 should not touch each other, but must maintain a safe distance between them to avoid pinching the massaged area. In this way the desired massage is provoked as described. The dimensions of the bodies 18 and 21 and the pivots 25 help maintain said safety distance.
En otra realización de la invención el elemento de masaje intermedio está constituido por una pletina 27 en cuya cara inferior incorpora una carcasa 30 en la que se aloja un motor 28 dotado de dos ejes opuestos 29 en cuyos extremos se han fijado unos contrapesos 31, de forma que la activación del motor 28 provoca un movimiento vibratorio de la pletina 27, la cual se fija mediante uno de sus extremos con unos tornillos 32 al bastidor 12, para permitir su vibración, de manera que al ubicarse la parte posterior de la pierna sobre la pletina, ésta transmite la vibración a la pierna, proporcionando un masaje vibratorio sobre la misma.In another embodiment of the invention, the intermediate massage element is constituted by a plate 27 on the underside of which incorporates a housing 30 in which a motor 28 is provided with two opposing shafts 29 at whose ends some weights 31, of so that the activation of the motor 28 causes a vibratory movement of the plate 27, which is fixed by one of its ends with screws 32 to the frame 12, to allow its vibration, so that when the back of the leg is located on the plate, this transmits the vibration to the leg, providing a vibrating massage on it.
La invención también prevé que la zona masajeada pueda ser de diferentes volúmenes, ya que por ejemplo el volumen de los gemelos de cada usuario varía en función de su constitución, lo que repercute en una ubicación de los gemelos diferente respecto a los discos la, Ib; 2a, 2b. Para resolver este inconveniente se incorporan medios para regular la separación entre los discos masajeadores la, Ib; 2a, 2b, de forma que dichos medios están constituidos por un cuarto elemento elástico, como por ejemplo puede ser un cuarto resorte 26, uno de cuyos extremos hace tope en el bastidor 12 y el otro extremo hace tope en el disco correspondiente, por ejemplo el disco 2b, que a su vez está retenido mediante un tope 13 de manera que la acción del cuarto resorte 26 mantiene los discos 2a, 2b en la posición más próxima entre sí. Esta estructura permite que al ubicarse una parte a masajear de mayor volumen, ésta presione contra los discos 2a, 2b, de modo que el disco 2a se desplaza axialmente sobre el segundo eje giratorio B, venciendo la acción del resorte 26 y adaptándose así al volumen de la parte a masajear de cada usuario. Una vez que se retira la parte masajeada, el disco 2a vuelve a su posición por la acción del cuarto resorte 26 contactando con el tope 13. Esta misma estructura puede aplicarse en los dos discos 2a y 2b simultáneamente.The invention also provides that the massaged area can be of different volumes, since for example the volume of the twins of each user varies depending on their constitution, which results in a location of the twins different from the la, Ib ; 2a, 2b. To solve this problem, means for regulating the separation between the massage discs la, Ib; 2a, 2b, so that said means are constituted by a fourth elastic element, such as for example a fourth spring 26, one of whose ends abuts the frame 12 and the other end abuts the corresponding disk, for example the disc 2b, which in turn is held by a stop 13 so that the action of the fourth spring 26 keeps the disks 2a, 2b in the closest position to each other. This structure allows that when a part to be massaged of greater volume is located, it presses against the disks 2a, 2b, so that the disc 2a moves axially on the second rotating axis B, overcoming the action of the spring 26 and thus adapting to the volume of the part to be massaged by each user. Once the massaged part is removed, the disc 2a returns to its position by the action of the fourth spring 26 contacting the stop 13. This same structure can be applied to the two discs 2a and 2b simultaneously.
En la realización preferida de la invención se prevé que todos los discos de masaje la, Ib; 2a, 2b estén asistidos por un cuarto resorte 26 para conseguir un mayor margen de adaptación a los diferentes volúmenes de las partes a masajear, de manera que se produce el desplazamiento venciendo la acción de los cuartos resortes 26 de ambos discos la, Ib; 2a, 2b de cada pareja de discos. In the preferred embodiment of the invention it is envisioned that all massage discs la, Ib; 2a, 2b are assisted by a fourth spring 26 to achieve a greater margin of adaptation to the different volumes of the parts to be massaged, so that the displacement occurs overcoming the action of the fourth springs 26 of both discs la, Ib; 2a, 2b of each pair of discs.
