ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Las actividades deportivas relacionadas con la musculación vienen desarrollándose desde la antigüedad donde se practicaban ejercicios de fuerza, como por ejemplo pruebas de levantamiento de pesos, inicialmente de piedras. 25 Ha habido una grandísima evolución de estas actividades a lo largo de la historia. En el siglo XIX surgieron exhibiciones de fuerza en las que se levantaban unas barras de hierro con enormes bolas de metal en sus extremos, y es a su vez en este siglo en el que surgieron también los gimnasios. Sports activities related to bodybuilding have been developing since ancient times where strength exercises were practiced, such as weightlifting tests, initially of stones. 25 There has been a great evolution of these activities throughout history. In the nineteenth century there were exhibits of strength in which iron bars were raised with huge metal balls at their ends, and it is in this century that gyms also emerged.
No es hasta un siglo después, que se inicia el gran desarrollo de las actividades de 30 musculación. Los elementos con los que se practican estas actividades de It is not until a century later, that the great development of 30 bodybuilding activities begins. The elements with which these activities are practiced
musculación por tanto han evolucionado en consonancia, principalmente en los últimos años en los que han aparecido sofisticadas máquinas de musculación. Bodybuilding has therefore evolved accordingly, mainly in recent years in which sophisticated weight training machines have appeared.
Estas máquinas tienen un problema principal que radica en su gran tamaño, por lo tanto y de forma general, éstas se ubican en gimnasios, salas de musculación o 5 lugares habilitados al respecto. Para ello destacamos patentes como la ES2152895 de GERVASPORT; la PCT/FR2000/002445 de ANGHEL MUSCOCEA; la PCT/FR2008/000725 de GILBERT DOUYÈRE; la ES1046279U de JUAN CARLOS LARGO GIL; o la ES0552666 de ARES. These machines have a main problem that lies in their large size, therefore and in general, these are located in gyms, gym rooms or 5 places enabled in this regard.

DESCRIPCIÓN DEL INVENTO DESCRIPTION OF THE INVENTION
El invento está compuesto por un conjunto formado por un mecanismo, que se encuentra en el interior de una carcasa de reducidas dimensiones, con el objeto de 25 que un cable o similar, que se encuentra alojado en el interior del mismo de una forma definida, se extraiga cuando se ejerce sobre él una fuerza de tracción superior a la resistencia que oponen tanto el propio mecanismo, como la actuación de un miembro secundario que se fija sobre el mecanismo de una manera determinada, quedando todo ello además resguardado por el afianzamiento de una 30 tapa situada sobre la superficie de la carcasa. The invention is comprised of an assembly formed by a mechanism, which is inside a small-sized housing, with the object that a cable or the like, which is housed inside it in a defined manner, it is extracted when a tensile force is exerted on it that is superior to the resistance that opposes both the mechanism itself, and the action of a secondary member that is fixed on the mechanism in a certain way, all of which is further protected by the securing of a 30 cover located on the surface of the housing.
El mecanismo está integrado por un mando tensor, un muelle helicoidal, un cilindro hueco, una leva principal, una leva secundaria, una rueda, un brazo palanca, un disco principal, un muelle espiral, una guía y todo ello accionado por la actuación sobre un cable por medio de un tirador. 5 The mechanism is integrated by a tensioning control, a helical spring, a hollow cylinder, a main cam, a secondary cam, a wheel, a lever arm, a main disc, a spiral spring, a guide and all this activated by the action on a cable by means of a handle. 5
El mando tensor está ubicado preferentemente en un lateral exterior de la carcasa de la máquina, de manera que puede ser manipulado por un usuario permitiendo el giro sobre su eje. Solidariamente a éste hay un muelle helicoidal que se comprime a lo largo del eje de rotación del citado mando tensor sobre la base de un cilindro 10 hueco en el cual se encuentra alojado, de forma que dependiendo del sentido de giro sobre el mando tensor, el muelle helicoidal se comprimirá en mayor o menor medida sobre la citada base. The tensioning control is preferably located on an outer side of the machine housing, so that it can be manipulated by a user allowing rotation on its axis. In solidarity with this there is a helical spring that is compressed along the axis of rotation of said tensioning control on the base of a hollow cylinder 10 in which it is housed, so that depending on the direction of rotation on the tensioning control, the Helical spring will be compressed to a greater or lesser extent on said base.
Asociado al cilindro hueco, se articula una leva principal por un extremo, del 15 mismo modo esta leva principal por su otro extremo se articula a un brazo palanca. Al contrario de la unión articulada entre la leva principal y el cilindro hueco que permite una oscilación longitudinal a lo largo del eje de rotación del mando tensor, la unión entre la leva principal con el brazo palanca es articulada respecto de un punto fijo, es decir, el brazo palanca se fija en ese extremo a la 20 carcasa sin posibilidad de desplazamiento. Associated with the hollow cylinder, a main cam is articulated at one end, in the same way this main cam at its other end is articulated to a lever arm. In contrast to the articulated joint between the main cam and the hollow cylinder that allows a longitudinal oscillation along the axis of rotation of the tensioner, the union between the main cam and the lever arm is articulated with respect to a fixed point, that is to say , the lever arm is fixed at that end to the housing without the possibility of movement.
Todo ello implica que el muelle helicoidal es solidario al cilindro hueco sobre el cual se comprime en su base, de manera que esta compresión será mayor o menor en función del sentido de giro que se ejerza sobre el mando tensor. Solidariamente 25 a este cilindro hueco se articula una leva principal la cual contiene en su interior, unida por medio de un pequeño eje, una leva secundaria. Esta leva secundaria tiene asociada una rueda de reducido tamaño que está en contacto con un disco principal. La rueda de reducido tamaño presiona al disco principal con mayor o menor fuerza en función de la compresión que en ese momento esté ejerciendo el 30 muelle sobre la base del cilindro hueco. All this implies that the helical spring is integral to the hollow cylinder on which it is compressed at its base, so that this compression will be greater or lesser depending on the direction of rotation exerted on the tensioning control. In solidarity with this hollow cylinder, a main cam is articulated which contains inside it, connected by means of a small shaft, a secondary cam. This secondary cam has a small wheel associated with a main disc. The small wheel presses the main disk with greater or lesser force depending on the compression that the spring is currently exerting on the base of the hollow cylinder.
El disco principal se ubica en el centro de la carcasa, con unas dimensiones determinadas por el tamaño de ésta, donde un cable o similar se aloja enrollado en su perímetro o contorno. A su vez asociado al disco principal y ubicado bajo éste hay un muelle espiral, de manera que cuando el disco principal gira para la 5 extracción del cable, por un lado el muelle espiral ejerce una resistencia a la fuerza de tracción del cable, y por otro lado tras el cese de la misma, el cable retorna a la posición inicial de enrollamiento sobre el perímetro del disco principal. The main disk is located in the center of the casing, with dimensions determined by the size of the casing, where a cable or similar is housed rolled in its perimeter or contour. In turn associated with the main disk and located under it there is a spiral spring, so that when the main disk rotates for the removal of the cable, on the one hand the spiral spring exerts a resistance to the tensile force of the cable, and by on the other hand after the cessation of the same, the cable returns to the initial winding position on the perimeter of the main disk.
10 10
Tangencialmente al disco principal, y en la zona más próxima al orificio de salida del cable por la carcasa, hay una guía acanalada con el objeto de dirigir el cable sobre el perímetro del disco principal. Tangentially to the main disk, and in the area closest to the cable exit hole through the housing, there is a grooved guide in order to direct the cable over the perimeter of the main disk.
Otro elemento del invento es un miembro o disco secundario, éste es extraíble y 15 se coloca o sitúa encima del disco principal introduciéndolo por un pivote situado en el mismo eje de rotación del citado disco principal. Another element of the invention is a member or secondary disk, this is removable and is placed or placed on top of the main disk by introducing it by a pivot located on the same axis of rotation of said main disk.
Puede haber distintos tipos discos secundarios, con distintas dimensiones y perfiles cada uno y se singularizan unos de otros porque cada uno de ellos posee unas protuberancias determinadas, en distintos puntos de su perímetro. Con el fin 20 de que cuando el disco principal gira, por la acción que se ejerce sobre el cable con una fuerza suficiente, y sale de la carcasa. Solidariamente el disco secundario también gira, de manera que las protuberancias mencionadas colisionan o chocan con la rueda que posee la leva secundaria (contenida a su vez en la leva principal), ya citada. 25 There may be different types of secondary disks, with different dimensions and profiles each and they are singled out from each other because each of them has certain protuberances, at different points of its perimeter. In order 20 that when the main disk rotates, by the action that is exerted on the cable with sufficient force, and exits the housing. In solidarity, the secondary disk also rotates, so that the aforementioned bumps collide or collide with the wheel that has the secondary cam (contained in turn in the main cam), already mentioned. 25
Este hecho produce que cuanto mayor es la presión que ejerce la rueda sobre los discos, y mayor es el tamaño de las protuberancias que posee el disco secundario, mayor es la tracción que ha de ejercer un individuo sobre la cuerda para extraerla. This fact produces that the greater the pressure exerted by the wheel on the discs, and the greater the size of the protuberances that the secondary disc possesses, the greater the traction that an individual has to exert on the rope to extract it.
Para evitar que el disco secundario se salga del pivote situado en el eje de rotación 30 del disco principal, tras el choque de sus protuberancias con la rueda que posee la To prevent the secondary disk from leaving the pivot located on the axis of rotation 30 of the main disk, after the clash of its protuberances with the wheel that has the
leva secundaria, se afianza mediante una muesca de anclaje al citado pivote el brazo palanca por un extremo. Quedando por tanto dicho brazo palanca, por un extremo afianzado mediante la muesca de anclaje, al pivote situado en el eje de rotación de los discos, y por el otro extremo está fijo a la carcasa, además de articulado con la leva principal, expuesto anteriormente. De manera que el brazo 5 palanca queda asegurado por encima de los discos evitando así que el disco secundario el cual es extraíble, salga despedido tras el choque con la rueda que posee la leva secundaria. secondary cam, is secured by an anchor notch to the aforementioned pivot the lever arm at one end. Therefore, said lever arm remains, at one end secured by the anchor notch, to the pivot located on the axis of rotation of the disks, and at the other end is fixed to the housing, in addition to articulated with the main cam, exposed above. . So that the lever arm 5 is secured above the discs thus avoiding that the secondary disc which is removable, comes off after the collision with the wheel that has the secondary cam.
De este modo, el brazo palanca al estar articulado en un punto fijo de la carcasa, 10 posee la movilidad suficiente para ser girado de tal manera que permite el recambio de los distintos discos secundarios que se quiera usar en cada caso. In this way, the lever arm when articulated at a fixed point of the housing, 10 has sufficient mobility to be rotated in such a way that it allows the replacement of the different secondary discs to be used in each case.
Otro detalle del invento, es la existencia de una tapa que cubre la totalidad del hueco que se necesita para el recambio del disco secundario, el cual se afianzará a 15 la carcasa de la máquina por un elemento de sujeción. Another detail of the invention is the existence of a cover that covers the entire gap that is needed for the replacement of the secondary disk, which will be secured to the casing of the machine by a fastener.
Una idea más amplia de las características del invento etc. en las que se han respetado las mismas referencias que en la patente principal para definir las partes 20 de estas que son comunes en este caso, dándole referencias complementarias para seguir con la misma tónica identificativa. A broader idea of the features of the invention etc. in which the same references have been respected as in the main patent to define the parts 20 of these that are common in this case, giving complementary references to continue with the same identifying tone.

DESCRIPCIÓN DE LOS DIBUJOS DESCRIPTION OF THE DRAWINGS
El invento está compuesto por un conjunto formado por un mecanismo (1) (Fig.3), 10 que se encuentra en el interior de una carcasa (2) (Fig.2) de reducidas dimensiones, con el objeto de que un cable (3) o similar, que se encuentra alojado en el interior del mismo de una forma definida, se extraiga cuando se ejerce sobre él una fuerza de tracción superior a la resistencia que oponen tanto el propio mecanismo (1), como la actuación de un disco secundario (4) (Fig.1 y Fig.4) que 15 se fija sobre el mecanismo (1) de una manera determinada, quedando todo ello además resguardado por el afianzamiento de una tapa (5) (Fig.1 y Fig.5) situada sobre la superficie de la carcasa (2). The invention is comprised of an assembly formed by a mechanism (1) (Fig. 3), 10 which is inside a casing (2) (Fig. 2) of reduced dimensions, in order that a cable ( 3) or similar, which is housed inside it in a defined way, when a tensile force greater than the resistance that both the mechanism itself (1) and the performance of a disk is exerted on it Secondary (4) (Fig. 1 and Fig. 4) that 15 is fixed on the mechanism (1) in a certain way, all of which is further protected by securing a cover (5) (Fig. 1 and Fig. 5 ) located on the surface of the housing (2).
El mecanismo (1) está integrado por un mando tensor (11) (Fig.2), un muelle 20 helicoidal (12), un cilindro hueco (13), una leva principal (14), una leva secundaria (141), una rueda (142), un brazo palanca (15), un disco principal (16), un muelle espiral (17), una guía acanalada (19) y todo ello accionado por la actuación sobre un cable (3) por medio de un tirador (31). The mechanism (1) is integrated by a tensioning control (11) (Fig. 2), a coil spring 20 (12), a hollow cylinder (13), a main cam (14), a secondary cam (141), a wheel (142), a lever arm (15), a main disk (16), a spiral spring (17), a grooved guide (19) and all this actuated by acting on a cable (3) by means of a handle (31).
25 25
El mando tensor (11) está ubicado preferentemente en un lateral exterior de la carcasa (2) de la máquina, de manera que puede ser manipulado por un usuario permitiendo el giro sobre su eje (a). Solidariamente a éste hay un muelle helicoidal (12) que se comprime a lo largo del eje de rotación (a) del citado mando tensor (11) sobre la base de un cilindro hueco (13) en el cual se encuentra alojado, 30 de forma que dependiendo del sentido de giro sobre el mando tensor (11), el The tensioning control (11) is preferably located on an outer side of the casing (2) of the machine, so that it can be manipulated by a user allowing rotation on its axis (a). In solidarity with it there is a helical spring (12) that is compressed along the axis of rotation (a) of said tensioning control (11) on the basis of a hollow cylinder (13) in which it is housed, 30 so that depending on the direction of rotation on the tensioning control (11), the
muelle helicoidal (12) se comprimirá en mayor o menor medida sobre la citada base. Helical spring (12) will be compressed to a greater or lesser extent on said base.
Asociado al cilindro hueco (13), se articula una leva principal (14) por un extremo, del mismo modo esta leva principal (14) por su otro extremo se articula 5 a un brazo palanca (15). Al contrario de la unión articulada (143) entre la leva principal (14) y el cilindro hueco (13) que permite una oscilación longitudinal a lo largo del eje de rotación (a) del mando tensor (11), la unión entre la leva principal (14) con el brazo palanca (15) es articulada respecto de un punto fijo (144), es decir, el brazo palanca (15) se fija en ese extremo a la carcasa (2) sin posibilidad 10 de desplazamiento. Associated with the hollow cylinder (13), a main cam (14) is articulated at one end, in the same way this main cam (14) at its other end is articulated 5 to a lever arm (15). In contrast to the articulated joint (143) between the main cam (14) and the hollow cylinder (13) which allows a longitudinal oscillation along the axis of rotation (a) of the tensioner control (11), the joint between the cam Main (14) with the lever arm (15) is articulated with respect to a fixed point (144), that is, the lever arm (15) is fixed at that end to the housing (2) without the possibility of movement.
Todo ello implica que el muelle helicoidal (12) es solidario al cilindro hueco (13) sobre el cual se comprime en su base, de manera que esta compresión será mayor o menor en función del sentido de giro que se ejerza sobre el mando tensor (11). 15 Solidariamente a este cilindro hueco (13) se articula una leva principal (14) la cual contiene en su interior, unida por medio de un pequeño eje, una leva secundaria (141). Esta leva secundaria (141) tiene asociada una rueda (142) de reducido tamaño que está en contacto con un disco principal (16). La rueda de reducido tamaño (142) presiona al disco principal (16) con mayor o menor fuerza en 20 función de la compresión que en ese momento esté ejerciendo el muelle helicoidal (12) sobre la base del cilindro hueco (13). All of this implies that the coil spring (12) is integral with the hollow cylinder (13) on which it is compressed at its base, so that this compression will be greater or lesser depending on the direction of rotation exerted on the tensioning control ( eleven). In solidarity with this hollow cylinder (13) a main cam (14) is articulated which contains inside it, connected by means of a small shaft, a secondary cam (141). This secondary cam (141) has an associated small wheel (142) that is in contact with a main disk (16). The small wheel (142) presses the main disk (16) with greater or lesser force depending on the compression that the helical spring (12) is currently exerting on the base of the hollow cylinder (13).
El disco principal (16) se ubica en el centro de la carcasa (2), con unas dimensiones determinadas por el tamaño de ésta, donde un cable (3) o similar se 25 aloja enrollado en su perímetro o contorno. A su vez asociado al disco principal (16) y ubicado bajo éste hay un muelle espiral (17), de manera que cuando el disco principal (16) gira para la extracción del cable (3), por un lado el muelle espiral (17) ejerce una resistencia a la fuerza de tracción del cable (3), y por otro lado tras el cese de la misma, el cable (3) retorna a la posición inicial de 30 enrollamiento sobre el perímetro del disco principal (16). The main disk (16) is located in the center of the housing (2), with dimensions determined by its size, where a cable (3) or the like is housed rolled in its perimeter or contour. In turn associated with the main disk (16) and located under it there is a spiral spring (17), so that when the main disk (16) rotates to remove the cable (3), on the one hand the spiral spring (17 ) exerts a resistance to the tensile force of the cable (3), and on the other hand after the cessation of the cable, the cable (3) returns to the initial position of 30 winding on the perimeter of the main disk (16).
Tangencialmente al disco principal (16), y en la zona más próxima al orificio (21) de salida del cable (3) por la carcasa (2), hay una guía acanalada (19) con el objeto de dirigir el cable (3) sobre el perímetro del disco principal (16). Tangentially to the main disk (16), and in the area closest to the hole (21) of the cable outlet (3) through the housing (2), there is a grooved guide (19) in order to direct the cable (3) on the perimeter of the main disk (16).

Otro elemento del invento es un disco secundario (4) (Fig.4), éste es extraíble y se coloca o sitúa encima del disco principal (16) (Fig.2) introduciéndolo por un pivote (18) situado en el mismo eje de rotación (b) del citado disco principal (16). Another element of the invention is a secondary disk (4) (Fig. 4), this is removable and placed or placed on top of the main disk (16) (Fig. 2) introducing it by a pivot (18) located on the same axis of rotation (b) of said main disk (16).
Puede haber distintos tipos discos secundarios (4), con distintas dimensiones y perfiles cada uno y se singularizan unos de otros porque cada uno de ellos posee 10 unas determinadas protuberancias (41), en distintos puntos de su perímetro. Con el fin de que cuando el disco principal (16) gira, por la acción que se ejerce sobre el cable (3) con una fuerza suficiente, y sale de la carcasa (2). Solidariamente el disco secundario (4) también gira, de manera que las protuberancias (41) mencionadas colisionan o chocan con la rueda (142) que posee la leva secundaria 15 (141) (contenida a su vez en la leva principal (14)), ya citada. There may be different types of secondary disks (4), with different dimensions and profiles each and they are singled out from each other because each of them has 10 certain protuberances (41), at different points of its perimeter. In order that when the main disk (16) rotates, by the action that is exerted on the cable (3) with sufficient force, and exits the housing (2). In solidarity, the secondary disk (4) also rotates, so that the aforementioned protuberances (41) collide or collide with the wheel (142) that has the secondary cam 15 (141) (in turn contained in the main cam (14)) , already cited.
Este hecho produce que cuanto mayor es la presión que ejerce la rueda (142) sobre la unión de los discos (16 y 4) (Fig.2 y Fig.1), y mayor es el tamaño de las protuberancias (141) que posee el disco secundario (41), mayor es la tracción que 20 ha de ejercer un individuo sobre la cuerda (3) para extraerla. This fact produces that the greater the pressure exerted by the wheel (142) on the union of the discs (16 and 4) (Fig. 2 and Fig. 1), and the larger the size of the protuberances (141) it possesses the secondary disk (41), the greater the traction that 20 has to exert an individual on the rope (3) to extract it.
Para evitar que el disco secundario (4) se salga del pivote (18) situado en el eje de rotación (b) del disco principal (16), tras el choque de sus protuberancias (41) con la rueda (142) que posee la leva secundaria (141), se afianza mediante una muesca 25 de anclaje (151) al citado pivote (18) el brazo palanca (15) por un extremo. Quedando por tanto dicho brazo palanca (15), por un extremo afianzado por medio de la muesca de anclaje (151), al pivote (18) situado en el eje de rotación (b) de los discos (16 y 4), y por el otro extremo está fijo a un punto (144) de la carcasa (2). 30 To prevent the secondary disk (4) from leaving the pivot (18) located on the axis of rotation (b) of the main disk (16), after the clash of its protuberances (41) with the wheel (142) that has the secondary cam (141), the lever arm (15) is secured by an end by means of an anchor notch (151) to said pivot (18) at one end. Therefore, said lever arm (15), at one end secured by means of the anchor notch (151), to the pivot (18) located on the axis of rotation (b) of the discs (16 and 4), and by the other end is fixed to a point (144) of the housing (2). 30
De manera que el brazo palanca (15) queda asegurado por encima de los discos (16 y 4) evitando así que el disco secundario (4) el cual es extraíble, salga despedido tras el choque con la rueda (142) que posee la leva secundaria (141). So that the lever arm (15) is secured above the discs (16 and 4), thus preventing the secondary disc (4) which is removable from being fired after the collision with the wheel (142) that has the cam secondary (141).
De este modo, el brazo palanca (15) al estar articulado en un punto fijo (144) de la 5 carcasa (2) (Fig.2), posee la movilidad suficiente para ser girado de tal manera que permite el recambio de los distintos discos secundarios (4) que se quiera usar en cada caso. Thus, the lever arm (15) being articulated at a fixed point (144) of the housing (2) (Fig. 2), has sufficient mobility to be rotated in such a way that it allows the replacement of the various secondary discs (4) that you want to use in each case.
Otro detalle del invento, es la existencia de una tapa (5) (Fig.1 y Fig.5) que cubre 10 la totalidad del hueco que se necesita para el recambio del disco secundario (4), el cual se afianzará a la carcasa (2) de la máquina por un elemento de sujeción (51). Another detail of the invention is the existence of a cover (5) (Fig. 1 and Fig. 5) covering the entire gap that is needed for the replacement of the secondary disk (4), which will be secured to the housing. (2) of the machine by a clamping element (51).
Una vez descrita convenientemente la naturaleza del invento, se hace constar a los efectos oportunos, que el mismo no queda limitado a los detalles exactos de esta 15 exposición, sino lo contrario, en él se introducirán las modificaciones que se consideren oportunas, siempre que se reivindican a continuación. Once the nature of the invention has been conveniently described, it is stated for the appropriate purposes that it is not limited to the exact details of this exhibition, but the contrary, it will introduce the modifications deemed appropriate, provided that claim below.
