Description

Carro de mano. Hand truck

OBJECT OF THE INVENTION

La presente invención se refiere a un carro de mano, del tipo de los que configuran un receptáculo de capacidad apropiada, dotado de ruedas para su desplazamiento sobre el suelo, y con un asidero superior que permite el fácil arrastre del mismo. The present invention relates to a hand carriage, of the type that configures a receptacle of appropriate capacity, provided with wheels for its movement on the ground, and with an upper handle that allows easy dragging thereof.

El objeto de la invención es conseguir un carro extraordinariamente simple desde el punto de vista estructural, y consecuentemente económico, que presenta además la especial particularidad de que desde el momento de su fabricación hasta su primera utilización adopta una configuración laminar y plana, que minimiza de forma muy considerable su ocupación volumétrica tanto durante su almacenamiento como durante su transporte. The object of the invention is to achieve an extraordinarily simple car from the structural point of view, and consequently economic, which also presents the special feature that from the moment of its manufacture until its first use it adopts a laminar and flat configuration, which minimizes very considerable volumetric occupation both during storage and during transport.

BACKGROUND OF THE INVENTION

A nivel individual o particular, son conocidos desde tiempo inmemorial carros de mano estructurado mediante un bastidor metálico, con al menos una pareja de ruedas inferiores y con un asidero superior, bastidor metálico al que se fija convenientemente un receptáculo generalmente de naturaleza textil, si bien en ocasiones también es de naturaleza plástica, con una capacidad adecuada para la carga.. On an individual or private level, hand-structured carriages are known from time immemorial by means of a metal frame, with at least one pair of lower wheels and with an upper handle, metal frame to which a receptacle generally of a textile nature is conveniently fixed, although Sometimes it is also of a plastic nature, with a suitable capacity for loading.

Estos carros, si bien cumplen de forma satisfactoria la función para la que han sido previstos, es decir la de transporte de los productos, presentan como problema fundamental su considerable volumetría y peso, ya que salen de fábrica con la definitiva configuración de uso, lo que supone una considerable ocupación volumétrica tanto a nivel de almacenaje como de transporte de los mismos, hasta su adquisición por parte del usuario, para el que se siguen manteniendo estos parámetros. These cars, although they satisfactorily fulfill the function for which they have been foreseen, that is, the transport of the products, present as a fundamental problem their considerable volumetry and weight, since they leave the factory with the definitive configuration of use, that supposes a considerable volumetric occupation so much at the level of storage as of transport of the same, until his acquisition by part of the user, for which they continue maintaining these parameters.

DESCRIPTION OF THE INVENTION

El carro de mano que la invención propone constituye en este momento el mayor avance evolutivo en la citada simplificación estructural, constituyendo un elemento capaz de adoptar una disposición totalmente plana, con una ocupación volumétrica mínima y siendo fácilmente transformable hacia su posición de uso, con una materia prima barata, como es el cartón, y con unas prestaciones muy similares a las de los carros convencionales. The hand carriage that the invention proposes constitutes at this time the greatest evolutionary advance in the aforementioned structural simplification, constituting an element capable of adopting a completely flat arrangement, with a minimum volumetric occupation and being easily transformable towards its position of use, with a cheap raw material, such as cardboard, and with benefits very similar to those of conventional cars.

Para ello de forma mas concreta, el carro que se preconiza está constituido mediante un cuerpo laminar, de cartón, convenientemente troquelado de manera que en el mismo se definen una serie de líneas de corte y de plegado, que permiten la transformación de dicho cuerpo plano en una cubeta de capacidad apropiada, con ruedas, cuya pared posterior se prolonga hacia arriba para rematarse en un asidero. To do this in a more concrete way, the carriage that is recommended is constituted by a laminar, cardboard body, conveniently stamped so that a series of cutting and folding lines are defined, which allow the transformation of said flat body in a bucket of appropriate capacity, with wheels, whose rear wall is extended upwards to finish off in a handle.

Específicamente en el citado cuerpo laminar y de cartón, con una resistencia apropiada, se define un sector constitutivo de la pared posterior del carro, de contorno tendente al rectángulo aunque ligeramente divergentes en sentido ascendente, que cerca de su extremidad superior cuenta con una ventana en funciones de asidero, quedando este sector delimitado por dos líneas de plegado laterales y una línea de plegado inferior. A través de ésta última y tras el sector correspondiente a la pared posterior del carro, se prolonga en un segundo sector constitutivo del fondo de la cubeta que define dicho carro, y mas allá de éste último en un tercer sector que constituye la pared anterior de la cubeta, pared que se relaciona con el sector de fondo a través de una línea intermedia de corte, prolongada hacia ambos lados en sendas líneas de plegado, si bien podría hacerlo a través de una línea única de plegado, como se verá mas adelante. Specifically in the mentioned laminar and cardboard body, with an appropriate resistance, a constituent sector of the rear wall of the carriage is defined, with a contour tending to the rectangle although slightly divergent in an upward direction, which near its upper extremity has a window in handle functions, this sector being limited by two lateral folding lines and a lower folding line. Through the latter and after the sector corresponding to the rear wall of the car, it extends into a second sector constituting the bottom of the bucket that defines said car, and beyond the latter in a third sector that constitutes the previous wall of the cuvette, a wall that relates to the bottom sector through an intermediate cutting line, extended to both sides in two fold lines, although it could be done through a single folding line, as will be seen later.

A ambos lados del sector constitutivo de la pared posterior del carro, se sitúan sendas solapas abatibles por las líneas de plegado que las relacionan con el sector posterior, mientras que el tercer sector, el correspondiente a la pared anterior del carro, se prolonga hacia ambos lados y a través de respectivas líneas de plegado en una segunda pareja de solapas que conjuntamente con las solapas anteriormente citadas, van a configurar las paredes laterales del carro. On both sides of the constituent sector of the rear wall of the carriage, folding flaps are located along the folding lines that relate them to the rear sector, while the third sector, that corresponding to the front wall of the carriage, extends towards both sides and through respective folding lines in a second pair of flaps that together with the aforementioned flaps, will configure the side walls of the carriage.

Estas segundas solapas se prolongan hacia las primeras y a través de respectivas líneas de plegado formando aletas destinadas a abatirse sobre el segundo sector del cuerpo laminar, el constitutivo del fondo del carro, rigidizando éste último. These second flaps extend towards the first and through respective folding lines forming fins intended to fold over the second sector of the laminar body, the constituent of the bottom of the car, stiffening the latter.

Para el armado del carro se ha previsto que tanto en las solapas posteriores como en las anteriores, existan orificios operativamente enfrentados en situación de armado, a través de los que se estabiliza tal situación con la colaboración de pequeños clips de plástico, si bien la fijación puede hacerse por cualquier otro medio convencional. For the assembly of the car, it has been foreseen that both on the rear and the previous flaps, there are holes operatively facing each other in armed situations, through which this situation is stabilized with the collaboration of small plastic clips, although the fixing It can be done by any other conventional means.

Por su parte las aletas intermedias, las destinadas a abatirse sobre el fondo del carro, cuentan también con orificios complementarios de otros existentes en dicho fondo y que en situación de armado se superponen, completándose el armado del carro mediante introducción en cada una de estas parejas de orificios de una especie de cazoleta que penetra a presión en los orificios y que incorpora en su seno una pequeña rueda parcialmente emergente de la cazoleta y que facilita el desplazamiento del carro sobre el suelo. On the other hand, the intermediate fins, those designed to be folded on the bottom of the car, also have complementary holes of other existing ones in said fund and that in an armed situation overlap, completing the car assembly by introducing each of these pairs of holes of a kind of bowl that penetrates under pressure in the holes and that incorporates in its bosom a small partially emerging wheel of the bowl and that facilitates the movement of the car on the ground.

Tal como anteriormente se ha dicho, el tercer sector del cuerpo laminar es abatible con respecto al segundo sector, el correspondiente al fondo, bien a través de una línea única de plegado, o bien a través de una línea de corte prolongados sus extremos en sendos tramos de línea de plegado. En este último caso la línea de corte es ligeramente curva, de manera que en el acodamiento del tercer sector con respecto al segundo, la línea de corte curva da lugar a una pequeña protuberancia en funciones de pata de apoyo del carro sobre el suelo, de contacto casi puntual. As previously stated, the third sector of the laminar body is foldable with respect to the second sector, the one corresponding to the bottom, either through a single folding line, or through a prolonged cutting line its ends in each sections of folding line. In the latter case, the cutting line is slightly curved, so that in the bending of the third sector with respect to the second, the curved cutting line gives rise to a small protrusion in function of the support leg of the car on the ground, of almost timely contact.

PREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas y en particular de la figura 1, puede observarse como el carro que se preconiza está constituido a partir de un cuerpo monopieza y de cartón, en el que se define un sector (1) destinado a constituir la pared posterior del carro, delimitado por dos líneas de plegado laterales (2, 2’), y por una línea de plegado inferior (3), contando este sector (1) con una ventana superior (4), alargada transversalmente, con la función de asidero y de dimensiones adecuadas para permitir el paso a su través de los dedos de la mano del usuario. In view of the figures outlined and in particular of Figure 1, it can be seen how the carriage that is recommended is constituted from a single piece and cardboard body, in which a sector (1) destined to constitute the wall is defined rear of the car, delimited by two lateral folding lines (2, 2 '), and by a lower folding line (3), this sector (1) having an upper window (4), extended transversely, with the function of handle and of adequate dimensions to allow passage through the fingers of the user's hand.

Este sector posterior (1) se prolonga, a través de la línea de plegado (3), en un segundo sector (5), que a su vez ha de constituir el fondo del carro, quedando este segundo sector (5) delimitado por dos líneas de corte laterales (6, 6’), y por una línea de corte (7), paralela a la línea (3) de precorte, rematada en cortos tramos extremos (7’) en los que la línea de corte (7) se transforma también en líneas de plegado. This rear sector (1) extends, through the folding line (3), in a second sector (5), which in turn must constitute the bottom of the car, leaving this second sector (5) delimited by two lateral cut lines (6, 6 '), and by a cut line (7), parallel to the pre-cut line (3), finished off in short end sections (7') in which the cut line (7) It is also transformed into fold lines.

Mas allá de estas líneas (7, 7’), el cuerpo laminar se prolonga en un tercer sector (8), que ha de constituir la pared frontal del carro, sector (8) enmarcado a través de dos líneas de plegado (9, 9’) por sendas solapas (10, 10’), que van a participar en la conformación de las paredes laterales del carro, al superponerse parcialmente a otras solapas (11, 11’), dispuestas a ambos lados del sector (1) correspondiente a la pared posterior del carro. Beyond these lines (7, 7 '), the laminar body extends into a third sector (8), which must constitute the front wall of the car, sector (8) framed through two folding lines (9, 9 ') by two flaps (10, 10'), which will participate in the conformation of the side walls of the car, partially overlapping other flaps (11, 11 '), arranged on both sides of the corresponding sector (1) to the rear wall of the car.

Estas solapas (10, 10’) y a través de respectivas líneas de plegado (12, 12’), se prolongan en aletas (13, 13’) destinadas a su vez a superponerse al sector intermedio (5), es decir al sector de fondo del carro, para rigidización de éste último. These flaps (10, 10 ') and through respective folding lines (12, 12'), are extended in fins (13, 13 ') destined in turn to overlap the intermediate sector (5), that is to say the sector of bottom of the car, for stiffening of the latter.

Como complemento de la estructura descrita, en el vértice libre de las solapas (10. 10’) emergente del sector frontal (8), se sitúan pequeños orificios (14, 14’), que en situación de armado del carro se superponen, es decir As a complement to the described structure, in the free vertex of the flaps (10. 10 ') emerging from the frontal sector (8), small holes (14, 14') are placed, which in the situation of assembling the car overlap, it is tell

5 quedan perfectamente enfrentados a otros orificios (15, 15’) existentes en las solapas complementarias (11, 11’), de manera que a través de estos orificios (14-15, 14’-15’), son pasantes clips de fijación (16), consistentes en dos pequeñas piezas de plástico, especialmente visibles en la figura 2, interacoplables machihembradamente y a presión con interposición de las dos solapas de cartón (10, 11) correspondientes. 5 are perfectly facing other holes (15, 15 ') existing in the complementary flaps (11, 11'), so that through these holes (14-15, 14'-15 '), are fixing clips (16), consisting of two small pieces of plastic, especially visible in Figure 2, interlocking tongue and groove and pressurized with interposition of the two corresponding cardboard flaps (10, 11).

10 De manera análoga, en las aletas (13, 13’) se establecen también orificios (17, 17’), en este caso de mayor diámetro, destinados a quedar enfrentados coaxialmente en situación de armado del carro a otros orificios similares (18, 18’) existentes en el segundo sector (5), que complementa el fondo de la caja. A través de estos orificios pasantes (17-18, 17’-18’) se introducen las cazoletas de plástico (19), como la mostrada en la figura 3, provistas de una valona (20) en funciones de tope limitador de penetración a través de los orificios citados, junto 10 Similarly, in the fins (13, 13 ') holes are also established (17, 17'), in this case of a larger diameter, intended to be coaxially faced in the car assembly situation to other similar holes (18, 18 ') existing in the second sector (5), which complements the bottom of the box. Through these through holes (17-18, 17'-18 ') the plastic cups (19) are introduced, as shown in Figure 3, provided with a wall (20) in functions of a penetration limit stop to through the mentioned holes, together

15 a la que se establece exteriormente un pequeño rehundido perimetral (21) que estabiliza dicha cazoleta con respecto al fondo del carro, cazoleta (19) en la que se aloja una rueda (22) con su correspondiente eje (23), rueda que resulta sobresaliente de la correspondiente cazoleta en una magnitud suficiente como para asegurar el correcto desplazamiento del carro sobre el suelo. 15 to which a small perimeter recess (21) is established externally that stabilizes said bowl with respect to the bottom of the car, bowl (19) in which a wheel (22) with its corresponding axle (23) is housed, resulting wheel protruding from the corresponding bowl in a sufficient magnitude to ensure the correct movement of the car on the ground.

20 Solo resta señalar por último que, como ya se ha apuntado con anterioridad, la línea de corte (7) curva y contrapuesta a los orificios (18, 18’), constituye una “pata” curvo convexa (24) de apoyo del carro sobre el suelo, cuando éste se encuentra en reposo. 20 It only remains to note finally that, as already noted above, the line of cut (7) curved and opposed to the holes (18, 18 '), constitutes a convex curved "leg" (24) supporting the carriage on the ground, when he is at rest.
