Carro con bastidor bloqueable.Trolley with lockable frame.
SECTOR DE LA TECNICATECHNICAL SECTOR
La presente invencion se refiere a un carro para portar mochilas u otros elementos, que incorpora un bastidor bloqueable.The present invention relates to a carriage for carrying backpacks or other elements, which incorporates a lockable frame.
Es de aplicacion en el campo de la fabrication de elementos de viaje, escolares y de transporte.It is applicable in the field of the manufacture of travel, school and transport elements.
ESTADO DE LA TECNICASTATE OF THE TECHNIQUE
Se conoce en el estado de la tecnica el modelo de utilidad ES1068123U que divulga un carro con un bastidor extensible unido a una base por una articulation (en este caso, dos articulaciones, una por cada barra del bastidor), y que posee sendos elementos de bloqueo para impedir el giro de la articulacion y el plegado del carro.It is known in the state of the art the utility model ES1068123U which discloses a carriage with an extendable frame attached to a base by an articulation (in this case, two joints, one for each bar of the frame), and which has two elements of lock to prevent the rotation of the joint and the folding of the car.
Este tipo de carro es habitual en la tecnica y ofrece una solution eficaz para portar mochilas. Sin embargo, la forma natural de uso es tirando del carro, con el brazo por detras del cuerpo. Ese tipo de posturas puede generar lesiones y problemas cuando la carga es demasiado elevada.This type of car is common in the art and offers an effective solution for carrying backpacks. However, the natural way of use is pulling the car, with the arm behind the body. Such postures can cause injuries and problems when the load is too high.
Si se desea situar la carga por delante, como es recomendado para evitar lesiones, el esfuerzo transmitido a lo largo del bastidor puede hacer que se salte el seguro de la barra telescopica, recogiendo el bastidor e impidiendo el avance.If it is desired to place the load in front, as recommended to avoid injuries, the effort transmitted along the frame can cause the telescopic bar lock to be skipped, picking up the frame and preventing the advance.
Es por lo tanto deseable disponer de un carro con un bastidor mas fiable, que pueda ser empujado en la position mas segura para el usuario.It is therefore desirable to have a car with a more reliable frame, which can be pushed into the safest position for the user.

El carro con bastidor bloqueable de la invention es del tipo que comprende una base con ruedas y un bastidor formado por al menos una barra telescopica. La barra telescopica, esta a su vez formada por una barra menor rematada en un asa y acoplada interiormente en una barra mayor. Esta barra mayor posee un puente proximo al extremo donde se acopla la barra menor. El puente, por su parte, tiene sendas aberturas para el paso de cada barra telescopica.The trolley with lockable frame of the invention is of the type comprising a base with wheels and a frame formed by at least one telescopic bar. The telescopic bar, in turn is formed by a smaller bar topped on a handle and internally coupled to a larger bar. This major bar has a bridge near the end where the minor bar is attached. The bridge, meanwhile, has two openings for the passage of each telescopic bar.
Ademas de estas caracterlsticas, el puente comprende al menos un taladro de paso de un seguro que intersecta con una abertura. Este taladro esta alineado con un ojo en la barra mayor que permite el contacto del seguro con la barra menor. Si el puente se situa a continuation de la barra mayor, no es necesario ese ojo, puesto que el seguro podra acceder directamente a la barra menor.In addition to these characteristics, the bridge comprises at least one drill hole of an insurance that intersects with an opening. This drill is aligned with an eye on the major bar that allows the insurance contact with the minor bar. If the bridge is located next to the main bar, that eye is not necessary, since the insurance can directly access the lower bar.
El seguro comprende una cabeza y un vastago con una muesca. El seguro, dentro del taladro posee una primera position en la que parte del vastago, o parte activa, esta situado dentro de la abertura y una segunda posicion en la que la muesca esta alineada con el ojo de la barra mayor y la abertura del puente, de forma que el seguro no interfiere con el movimiento de la barra menor.The insurance comprises a head and a rod with a notch. The lock, inside the drill has a first position in which part of the rod, or active part, is located inside the opening and a second position in which the notch is aligned with the eye of the main bar and the opening of the bridge , so that the insurance does not interfere with the movement of the minor bar.
Para poder relacionarse con el seguro, la barra menor posee al menos una ranura de dimensiones acordes con la parte de vastago situable dentro de la abertura, y alineable con el vastago y el taladro. Por cada ranura que se situa alineada con el taladro del puente se generara una posicion estable del bastidor.In order to be able to relate to the insurance, the minor bar has at least one groove of dimensions in accordance with the rod part located within the opening, and aligned with the rod and the hole. A stable frame position will be generated for each slot that is aligned with the bridge drill.
Se prefiere que el carro posea un conjunto de seguro por cada barra telescopica.It is preferred that the car has a set of insurance for each telescopic bar.
Para facilitar la introduction del vastago en la ranura sin que la barra menor pierda resistencia, se prefiere que el vastago posea un estrechamiento adyacente a la muesca. Este estrechamiento corresponde a la parte activa del vastago, que queda dentro de la abertura en la primera posicion del seguro.To facilitate the introduction of the rod into the groove without the minor bar losing strength, it is preferred that the rod has a narrowing adjacent to the notch. This narrowing corresponds to the active part of the rod, which remains inside the opening in the first position of the insurance.
El seguro puede comprender un resorte de retorno a la primera posicion.The lock may comprise a spring return to the first position.
La posicion relativa entre la muesca y la parte del vastago que queda dentro de la abertura definira el tipo de movimiento necesario para pasar de la primera posicion, oThe relative position between the notch and the part of the rod that remains within the opening will define the type of movement necessary to move from the first position, or

MODOS DE REALIZACION DE LA INVENCIONEMBODIMENTS OF THE INVENTION
A continuation se pasa a describir de manera breve un modo de realization de la invencion, como ejemplo ilustrativo y no limitativo de esta, basado en las figuras aportadas.Next, a mode of realization of the invention is briefly described, as an illustrative and non-limiting example of this, based on the figures provided.
La invencion esta prevista para un carro como el mostrado en el ejemplo de las figuras 1A y 1B. Comprende una base (1) de soporte de una mochila, con unas ruedas (2) y un bastidor (3) telescopico.The invention is provided for a car as shown in the example of Figures 1A and 1B. It comprises a base (1) for supporting a backpack, with wheels (2) and a telescopic frame (3).
El bastidor (3) tiene una posicion replegada (figura 1B) y al menos una posicion desplegada (Fig.1A). Para ello, el bastidor (3) esta formado por una serie de barras telescopicas (4,4’) que se unen por la parte superior en un asa (5), y por la parte media en un puente (6). En la posicion replegada, el asa (5) queda a la altura del puente (6), y preferiblemente escondida parcialmente en este.The frame (3) has a folded position (figure 1B) and at least one unfolded position (Fig. 1A). For this, the frame (3) is formed by a series of telescopic bars (4.4 ’) that are joined by the upper part in a handle (5), and by the middle part in a bridge (6). In the stowed position, the handle (5) is at the height of the bridge (6), and preferably partially hidden therein.

Entre la base (1) y el puente (6) se disponen unas barras mayores (4’), donde se acoplan las barras menores (4) que son las que se desplazan para alargar el bastidor. Como es conocido en la tecnica, las barras menores (4) poseen unas marcas, formadas por incisiones u orificios que senalan las posiciones estables del bastidor. Cuando solo poseen una marca, solo existe una posicion desplegada. Si se crean varias, existen varias posiciones estables. Por otro lado, las barras menores (4) poseen unos topes que impiden la salida completa del interior de las barras mayores (4’).Between the base (1) and the bridge (6) there are some larger bars (4 ’), where the smaller bars (4) are coupled, which are those that move to lengthen the frame. As is known in the art, the smaller bars (4) have marks, formed by incisions or holes that mark the stable positions of the frame. When they only have one brand, there is only one position displayed. If several are created, there are several stable positions. On the other hand, the smaller bars (4) have stops that prevent the complete exit of the interior of the larger bars (4 ’).
La realizacion preferida de la invencion se muestra en las figuras 2 a 5. Se aprecia como la posicion estable de las barras menores (4) se genera a partir de un seguro (7) en el puente (6). Generalmente, se dispondra un seguro (7) por cada juego de barras (4, 4’), dispuesto en sendos taladros (61) del puente (6).The preferred embodiment of the invention is shown in Figures 2 to 5. It can be seen how the stable position of the minor bars (4) is generated from a lock (7) on the bridge (6). Generally, insurance (7) will be provided for each set of bars (4, 4 ’), arranged in two holes (61) of the bridge (6).
Una realizacion del seguro (7) se muestra en detalle en la figura 2. Comprende una cabeza (71), por donde podra ser accionado, y un vastago (72) con una muesca (73) en un lateral. En la figura se observa como muesca (72) esta bordeada por un estrechamiento (74) de enclavamiento, que corresponde a un tramo del vastago (72) de menor anchura, y dispuesto en el borde de la muesca (73) mas alejada de la cabeza (71). Este estrechamiento (74) corresponde a la parte activa del vastago (72). Es igualmente posible, aunque esta alternativa no se ha representado, que el estrechamiento (74) este proximo a la cabeza (71).An embodiment of the insurance (7) is shown in detail in Figure 2. It comprises a head (71), where it can be operated, and a rod (72) with a notch (73) on one side. The figure shows how notch (72) is bordered by a narrowing (74) of interlocking, which corresponds to a section of the rod (72) of smaller width, and arranged at the edge of the notch (73) farther from the head (71). This narrowing (74) corresponds to the active part of the rod (72). It is equally possible, although this alternative has not been represented, that the narrowing (74) is close to the head (71).
Por su parte, el puente (6) posee el taladro (61) proximo a la abertura (62) de paso de las barras telescopicas (4,4’), de forma que el seguro (7) pueda influir sobre estas. Para ello, en una primera posicion el estrechamiento (74) se situa dentro de la abertura (62) (figura 4A) y en una segunda posicion, el estrechamiento (74) sale de la abertura (62) y el conjunto del seguro (7) quede por fuera de esta (figura 4B). Para ello, la muesca (73) sera de dimensiones acordes a la abertura (62) para no entorpecer el paso de la barra menor (4) (figura 4).For its part, the bridge (6) has the borehole (61) near the opening (62) of the telescopic bars (4.4 ’), so that the lock (7) can influence them. For this, in a first position the narrowing (74) is located inside the opening (62) (figure 4A) and in a second position, the narrowing (74) leaves the opening (62) and the insurance assembly (7 ) is out of this (figure 4B). For this, the notch (73) will be of dimensions according to the opening (62) so as not to obstruct the passage of the minor bar (4) (Figure 4).
La posicion de la barra mayor (4’) debe permitir que el seguro (7) entre en contacto con la barra menor (4). Por lo tanto, estara por debajo del puente (6) o poseera un ojo que permita el acceso. Finalmente, la barra menor (4) poseera al menos una ranura (no mostrada) de tamano correspondiente al estrechamiento (73), de forma que el estrechamiento (73) pueda entrar en la ranura con escaso juego. PreferiblementeThe position of the major bar (4 ’) must allow the safety (7) to come into contact with the minor bar (4). Therefore, it will be under the bridge (6) or have an eye that allows access. Finally, the smaller bar (4) will have at least one groove (not shown) of size corresponding to the narrowing (73), so that the narrowing (73) can enter the groove with little play. Preferably

poseera una ranura para la posicion desplegada y una ranura para la posicion de plegado.It will have a groove for the deployed position and a groove for the folded position.
Si el vastago (72) posee el estrechamiento (74), y la ranura es acorde, entre si definen todas las posiciones posibles del seguro (7), que no puede ser extraido del taladro (61) ya que el resto del vastago (72) no puede pasar por la ranura.If the rod (72) has the narrowing (74), and the groove is in accordance with each other, they define all the possible positions of the insurance (7), which cannot be removed from the drill (61) since the rest of the rod (72 ) cannot pass through the slot.
Este mecanismo es especialmente solido pues el esfuerzo de retirada del seguro (7) es completamente transversal al esfuerzo transmitido por el bastidor (3), de forma que no es posible una liberacion accidental. Por lo tanto, es posible empujar a lo largo del bastidor (3), como cuando se situa el carro por delante del usuario.This mechanism is especially solid because the effort to remove the insurance (7) is completely transverse to the effort transmitted by the frame (3), so that an accidental release is not possible. Therefore, it is possible to push along the frame (3), such as when the carriage is placed in front of the user.
Para utilizar este carro, el usuario partira de una posicion replegada (generalmente no enclavada por el seguro (7)) y estirara del asa (5) para separarla del puente (6), desplegando la barra telescopica (4,4’). Cuando se alcanza la posicion deseada, que puede venir senalada en la barra menor (4), actua sobre los seguros (7), que se introducen en las ranuras de las barras menores (4) respectivas. En ese momento, el bastidor (3) esta perfectamente afianzado y se puede empujar el carro.To use this car, the user will start from a stowed position (usually not locked by the safety lock (7)) and pull the handle (5) to separate it from the bridge (6), deploying the telescopic bar (4.4 ’). When the desired position is reached, which may be indicated in the minor bar (4), it acts on the locks (7), which are introduced into the slots of the respective minor bars (4). At that time, the frame (3) is perfectly secured and the carriage can be pushed.
Para su recogida, se actua sobre la cabeza (71) del seguro (7) y se puede proceder a replegar el bastidor (3) para reducir sus dimensiones.To collect it, the head (71) of the insurance (7) is actuated and the frame (3) can be retracted to reduce its dimensions.
El seguro (7) puede comprender un resorte que le haga tender a la primera posicion, o posicion de bloqueo de las barras telescopicas (4,4’).The latch (7) may comprise a spring that makes it tend to the first position, or position for locking the telescopic bars (4.4 ’).
La combination de material y forma del seguro (7) debera ser suficientemente resistente para transmitir los esfuerzos entre ambas partes de la barra telescopica (4,4’), como polipropileno o resina.The combination of material and shape of the insurance (7) should be strong enough to transmit the forces between both parts of the telescopic rod (4.4 ’), such as polypropylene or resin.
