Description
DISPOSITIVO DE FRENO AUTOMÁTICO PARA CARRO DE BEBÉ AUTOMATIC BRAKE DEVICE FOR BABY CARRIER
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCION OBJECT OF THE INVENTION
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo de freno automático para carro de bebé que básicamente consiste en un sistema muy sencillo, sin ningún tipo de complicaciones y con un único objetivo, impedir que nunca la vida de un niño dependa de los muchos descuidos e imperfecciones del ser humano; como, por ejemplo, cuando el carrito es empujado por el hermano mayor que sigue siendo un niño, también los abuelos que en algunos casos ya no están en plenas facultades o la mamá que se pone los zapatos de tacón (inestables) o cuando se nos olvida coger las gafas de sol u otros descuidos y en un momento si no hemos frenado convenientemente el carro del bebé, este puede movilizarse en dirección peligrosa, pudiendo poner en peligro la integridad del bebé. The present invention, as expressed in the title of this descriptive memory, refers to an automatic brake device for a baby carriage that basically consists of a very simple system, without any type of complications and with a single objective, to prevent the life of a child depends on the many carelessness and imperfections of the human being; such as, for example, when the cart is pushed by the older brother who is still a child, also the grandparents who in some cases are no longer in full capacity or the mother who puts on high-heeled shoes (unstable) or when we are forget to take the sunglasses or other carelessness and in a moment if we have not properly braked the baby carriage, it can move in a dangerous direction, endangering the integrity of the baby.
CAMPO DE LA INVENCION FIELD OF THE INVENTION
El campo de la invención corresponde a la industria auxiliar de dispositivos de seguridad para carros de bebé. The field of the invention corresponds to the auxiliary industry of safety devices for baby carriages.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
La mayoría de los carros de bebé cuentan con sistemas de freno. Most baby carriages have brake systems.
Pero todos estos sistemas de freno son sistemas estáticos, es decir, cuando deseas dejar frenado el carro del bebé accionas un freno convencional, normalmente sobre alguna de las ruedas y el carro queda frenado hasta que desconectas el freno. But all these brake systems are static systems, that is, when you want to brake the baby carriage, you apply a conventional brake, normally on one of the wheels, and the carriage remains braked until you disconnect the brake.
Esta situación implica que quieres frenar el carro y lo haces de una forma consciente. This situation implies that you want to stop the car and you do it consciously.
Pero ¿qué ocurre cuando tienes un descuido aunque sea momentáneo? But what happens when you have an oversight, even momentary?
Pues que el carro con sus cuatro ruedas se puede deslizar fácilmente a poca pendiente que exista o ligero empujón que le impulse, lo que puede significar un gran peligro para el infante que se encuentra dentro. Well, the cart with its four wheels can slide easily on a slight slope that exists or a slight push that propels it, which can mean great danger for the infant that is inside.
Para evitar este posible y peligroso problema, el inventor ha diseñado un novedoso mecanismo que de forma automática en caso de descuido o accidente, el carro del bebé queda automáticamente frenado.
El inventor no conoce ningún antecedente similar de referencia To avoid this possible and dangerous problem, the inventor has designed an innovative mechanism that automatically brakes the baby carriage in the event of carelessness or an accident. The inventor is not aware of any similar antecedent of reference
BREVE DESCRIPCIÓN DE LA INVENCIÓN BRIEF DESCRIPTION OF THE INVENTION
La presente invención de modelo de utilidad se refiere a un dispositivo automático de freno para carro de bebé que se encuentra constituido a partir de un chasis de carro de bebé y, en dicho chasis, se aprecia en la barra superior de conducción que en sus dos extremos incluye un sistema giratorio que movilizan un cable que discurre por el interior de una funda que se encuentra sujeta por medio de un prisionero a una carcasa prismática que contiene un muelle que moviliza un bulón cilindrico que presiona a la otra parte del dispositivo de freno conformada por un tambor que conlleva un taladro central, para el paso del eje de las ruedas y varios taladros en las caras internas y enfrentadas de los tambores. The present utility model invention refers to an automatic brake device for a baby carriage that is made from a baby carriage chassis and, in said chassis, it can be seen in the upper driving bar that in its two The ends include a rotating system that mobilizes a cable that runs through the interior of a sheath that is attached by means of a prisoner to a prismatic casing that contains a spring that mobilizes a cylindrical bolt that presses the other part of the brake device. by a drum that includes a central hole, for the passage of the wheel axle and several holes on the internal and opposite faces of the drums.
El dispositivo de freno es manejado desde las empuñaduras giratorias, de forma que cuando se quedan sin presión giratoria las empuñaduras, el muelle se dispara automáticamente empujando el bulón contra el tambor de forma que dicho bulón se introduce por cualquiera de los taladros, deteniendo inmediatamente el carro de bebé. The brake device is controlled from the rotary handles, so that when the handles run out of rotary pressure, the spring is automatically triggered, pushing the bolt against the drum so that said bolt is inserted through any of the holes, immediately stopping the brake. baby carriage.
