BACKGROUND OF THE INVENTION

Es un hecho que las mochilas con ruedas, maletas, carros de It is a fact that backpacks with wheels, suitcases, cars

compra, etc., en unos casos son arrastradas mediante agarre manual, provocando en primer lugar una asimetría en el cuerpo del usuario, al tender el hombro del brazo de agarre a quedar situado mas atrasado que el otro hombro, con la consiguiente asimetría del cuerpo o espalda del usuario y el riesgo de lesiones, dolencias, etc. purchase, etc., in some cases they are dragged by manual grip, first causing an asymmetry in the user's body, as the shoulder of the grip arm tends to be located more behind than the other shoulder, with the consequent asymmetry of the body or back of the user and the risk of injuries, ailments, etc.

En otros casos las mochilas, por ejemplo, son transportadas sobre la espalda del usuario, lo que da lugar a una carga que también puede provocar dolencias y lesiones en el usuario. In other cases, backpacks, for example, are transported on the user's back, which results in a load that can also cause ailments and injuries to the user.

DESCRIPTION OF THE INVENTION

El dispositivo que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, en base a una solución sencilla pero enormemente eficaz. The device that has been recommended has been designed to solve the problem described above, based on a simple but highly effective solution.

Mas concretamente, el dispositivo de la invención se constituye a partir de un eje extensible y/o telescópico que por un extremo se relaciona con el propio bastidor de la mochila rodante, maleta o elemento similar, mientras que por el extremo opuesto, el aludido eje telescópico y/o extensible, a través de una rótula, se relaciona con un dorsal anatómico que forma parte de un arnés que se dispone sobre los hombros y espalda del usuario, de manera tal que en virtud de la extensibilidad del eje y de la articulación en rótula entre éste y el dorsal anatómico, la mochila, maleta o similar, puede ser arrastrada sin necesidad de agarre manual y sin necesidad de ir suspendida en la espalda del usuario, ya que esa telescopicidad del eje proporciona la suficiente longitud para que la mochila, maleta o similar quede apoyada a través de sus ruedas en el suelo, y ser arrastrada desde la espalda del usuario, es decir, sin tener que trabajar el cuerpo de forma asimétrica, sin necesidad
More specifically, the device of the invention is constituted from an extensible and / or telescopic axle that at one end is related to the frame of the rolling backpack, suitcase or similar element, while at the opposite end, the aforementioned axis telescopic and / or extensible, through a kneecap, it is related to an anatomical dorsal that is part of a harness that is arranged on the shoulders and back of the user, so that by virtue of the extensibility of the shaft and the joint in a patella between this and the anatomical dorsal, the backpack, suitcase or similar, can be dragged without the need for a manual grip and without the need to be suspended on the user's back, since that telescopic axis provides enough length for the backpack , suitcase or similar is supported through its wheels on the ground, and be dragged from the user's back, that is, without having to work the body asymmetrically, without needing

del agarre manual y sin necesidad, como se decía con anterioridad, de llevar suspendida la carga que constituye la mochila, maleta o similar. of the manual grip and without the need, as previously stated, of carrying the load that constitutes the backpack, suitcase or similar suspended.
