CAMPO TECNICO  TECHNICAL FIELD
La presente invención describe un sistema mecánico creado en base a diversos elementos, los cuales, armados en una máquina, esta máquina ejercita la estructura muscular del usuario al este accionarla con movimientos de la parte del cuerpo que correspondientemente a la máquina que corresponde a la zona del cuerpo que correspondientemente al dispositivo que se use, se deben ejecutar para accionar su dinámica; esta invención está relacionada con las necesidades de las personas que por diversos motivos desean ejercitarse en un gimnasio. The present invention describes a mechanical system created on the basis of various elements, which, armed in a machine, this machine exercises the muscular structure of the user to the east to operate it with movements of the part of the body corresponding to the machine corresponding to the area of the body that corresponding to the device that is used, must be executed to activate its dynamics; This invention is related to the needs of people who for various reasons want to exercise in a gym.
ESTADO DE LA TECNICA STATE OF THE ART
En la actualidad existen para el ejercitamiento muscular diversos elementos, como las pesas y máquinas de gimnasio, con los cuales, los usuarios al manipularlas con ciertos movimientos generan el esfuerzo en el músculo que este requiere para su desarrollo, estos elementos y equipos convencionales de gimnasio son utilizados para diversos fines, los cuales pueden variar desde por cuestiones de salud, competencia, en el caso de ios atletas o incluso por estética para obtener un abdomen piano o brazos con mayor volumen muscular, etcétera. At present there are various elements for muscle exercise, such as weights and gym machines, with which users, when manipulating them with certain movements, generate the effort in the muscle that this requires for their development, these elements and conventional gym equipment. They are used for various purposes, which can vary from health issues, competition, in the case of athletes or even aesthetics to obtain a piano abdomen or arms with greater muscle volume, and so on.
La técnica habitual requiere el manipular los elementos y equipos antes mencionados con movimientos del cuerpo, para que el músculo reciba el estímulo que requiere para su desarrollo, siendo aquellos elementos y equipos, pesados objetos que al ser usados pueden causar lesiones ya sea por el riesgo de la manipulación de estos, tanto si cae sobre el usuario, como por el esfuerzo ejercido sobre la columna vertebral que implica su manipulación, siendo esta la principal causa de lesiones que conllevan las personas que se ejercitan con estos elementos, esto inside en que según lo requiera la exigencia de la persona, quien, mientras más se fortalece, más peso se ve obligado a manipular para obtener resultados. The usual technique requires manipulating the aforementioned elements and equipment with movements of the body, so that the muscle receives the stimulus that it requires for its development, being those elements and equipment, heavy objects that when used can cause injuries due to the risk of the manipulation of these, whether it falls on the user, or the effort exerted on the spine that implies its manipulation, this being the main cause of injuries that entail the people who exercise with these elements, this inside in that according to the requirement of the person requires it, who, the more he strengthens himself, the more weight he is forced to manipulate in order to obtain results.
Sin embargo esto implica primero, tener que ir a un lugar especializado como es un gimnasio para encontrar todos los elementos que se requieren para obtener un trabajo eficiente y completo para el músculo ya que sería imposible para cualquier persona común poseer dicha cantidad de máquinas y elementos, esto lleva a tener que transportarse a estos lugares utilizando su tiempo el cual es muy apreciado hoy en día, además de esto, también que desde antes del ejercicio ya se empieza a sufrir un desgaste de energía para preparar los elementos, como cargar los discos de hasta 25 kilogramos o incluso más para preparar las máquinas y demás elementos, como las barras para el ejercicio o simplemente el tomar las mancuernas las cuales pueden llegar a superar los 30 kilogramos cada una, siendo este un pre-desgaste al ejercicio, siendo este detalle un factor que incrementa la posibilidad de una lesión, y se debe agregar también que estos elementos son manipulados por muchas otras personas y esto implica un riesgo de contaminación biológica además de la incomodidad de encontrar frecuentemente en los gimnasios desagradables olores ajenos, causados por la transpiración de las demás personas, cargando así desagradablemente el ambiente. However, this implies first, having to go to a specialized place such as a gym to find all the elements that are required to obtain an efficient and complete work for the muscle since it would be impossible for any ordinary person to have such amount of machines and elements. , this leads to having to travel to these places using their time which is very appreciated today, in addition to this, also since before the exercise and begins to suffer a waste of energy to prepare the items, such as loading discs of up to 25 kilograms or even more to prepare the machines and other elements, such as exercise bars or simply taking the dumbbells which can exceed 30 kilograms each, this being a pre-wear to exercise, this detail a factor that increases the possibility of an injury, and it should also be added that these elements are manipulated by many other people and this implies a risk of biological contamination in addition to the discomfort of frequently finding in the unpleasant gyms other people's odors, caused by perspiration of other people, thus unpleasantly charging the environment.
DESCRIPCION DE LA INVENCION DESCRIPTION OF THE INVENTION
Como solución a los problemas antes mencionados, se desarrolló la presente invención, la cual consiste en un sistema mecánico, el cual, al ser ensamblados sus elementos, conciben una máquina, la cual al ser accionada por el usuario, este, ejercita los músculos de la zona a la que va orientada dicha máquina, a continuación se presentará preferentemente el ejemplo de una maquina orientada a ejercitar los músculos del antebrazo y esta comprende de las siguientes partes: As a solution to the aforementioned problems, the present invention was developed, which consists of a mechanical system, which, when assembled its elements, conceive a machine, which when operated by the user, this, exercises the muscles of the area to which said machine is oriented, next, the example of a machine designed to exercise the muscles of the forearm will preferably be presented and it comprises the following parts:
Un elemento estático, el cual presenta una forma de arco en cuya base presenta una extensión en cada lado de este, las cuales en su extremo presentan un orificio; un elemento de sujeción al cuerpo, el cual sujeta la máquina al cuerpo del usuario (siendo preferentemente para este ejemplo, una correa de velero); un elemento base de sujeción para el elemento de retracción, el cual preferentemente para este caso es una estructura tubular que está doblada primero en sus dos extremos hacia adelante y luego hacia abajo, también por sus dos extremos hacia abajo el cual está empernada al elemento estático; un elemento móvil, el que presenta en su estructura dos piezas iguales con forma de símbolo de "raíz cuadrada" los cuales están unidos por medio de los elementos de estructuración, los cuales son: un elemento para asir, el cual es un asa para sujetar con la mano; un eje de funcionamiento, que permite que el sistema se mueva; un elemento de sujeción para el elemento de retracción, en el cual está sujetado el elemento de retracción, en el cual está sujetado el elemento de retracción; un tope de palanca, que es el que impondrá la presión al elemento de retracción al momento de accionar la máquina. Esta máquina comprende preferentemente de un elemento estático unido en un extremo al elemento de sujeción al cuerpo por un lado y al elemento base de sujeción para el elemento de retracción, y en el otro extremo al elemento móvil, acoplados estos por el eje de funcionamiento, estos dos elementos son armados al colocarles el elemento de retracción por un extremo en el elemento base de sujeción para el elemento de retracción y por el otro al elemento de sujeción para el elemento de retracción, una vez armada la máquina, esta se sujeta al usuario en el antebrazo por medio del elemento de sujeción al cuerpo, colocando el eje de funcionamiento sobre la muñeca y sujetando con la mano el elemento para asir, así pues, una vez puesta la máquina se procede a accionarla con movimientos de apalancamiento de la muñeca, los cuales mueven la máquina haciendo que se estire el elemento de retracción, el cual por defecto a su vez, jala la máquina para que esta regrese a su estado inicial, causando esto el efecto de presión que se requiere para estimular al músculo. A static element, which has an arc shape whose base has an extension on each side thereof, which at its end have an orifice; a fastening element to the body, which holds the machine to the body of the user (preferably for this example, a sailboat strap); a basic support element for the retraction element, which preferably for this case is a tubular structure that is first bent at its two ends forward and then downwards, also at its two ends downwards which is bolted to the static element ; a mobile element, which presents in its structure two equal pieces in the form of a symbol of "square root" which are united by means of the structuring elements, which are: an element to grasp, which is a handle to hold with hand; an operating axis, which allows the system to move; a clamping element for the retraction element, in which the retraction element is held, in which the retraction element is held; a lever stop, which is the one that will impose the pressure on the retraction element when operating the machine. This machine preferably comprises a static element attached at one end to the body-holding element on one side and to the base-holding element for the retraction element, and at the other end to the mobile element, these being coupled by the operating shaft, these two elements are armed by placing the retraction element at one end in the element base for the retraction element and on the other to the clamping element for the retraction element, once the machine is assembled, this is fastened to the user in the forearm by means of the body fastening element, placing the axle working on the wrist and holding the grasping element with the hand, so, once the machine is put on, it is operated with leverage movements of the wrist, which move the machine causing the retraction element to stretch, which by default in turn, pulls the machine so that it returns to its initial state, causing this effect of pressure that is required to stimulate the muscle.
Ello supone una mejora en el estado de la técnica, ya que al ser una máquina hecha con elementos muy ligeros, ofrece una seguridad integral, la cual no se encuentra en ningún otro elemento de ejercitamiento convencional, así pues es una máquina que económicamente no causa ningún impacto al utilizarla, además que ai tener estas características, permite que sea un aparato que se puede tener sin riesgos por sus pesos ni problemas por el espacio en casa, descartando también el tener que usar máquinas de gimnasio que podrían estar contaminadas (y así sucede con frecuencia) con agentes patógenos y el tener que soportar olores desagradables, muy frecuentes en estos lugares. This supposes an improvement in the state of the art, since being a machine made with very light elements, it offers an integral security, which is not found in any other element of conventional exercise, so it is a machine that does not economically cause no impact when using it, in addition to having these characteristics, it allows it to be a device that can be safely carried out due to its weight or problems due to the space at home, also ruling out the need to use gym machines that could be contaminated (and thus it happens frequently) with pathogens and having to endure unpleasant odors, very frequent in these places.
