HERRAMIENTA CAVADORA  CAVADORA TOOL
D E S C R I P C I O N D E S C R I P C I O N
OBJETO DE LA INVENCION OBJECT OF THE INVENTION
La presente invención se refiere a una herramienta cavadora, prevista concretamente para utilizarse en jardinería y en cualquier otro supuesto práctico en el que se requiera efectuar el cavado del terreno. The present invention relates to a digging tool, specifically intended for use in gardening and in any other practical case in which it is required to do the digging of the ground.
El objeto de la invención es facilitar y reducir al máximo el trabajo que hay que realizar a la hora de llevar a cabo el cavado del suelo para labrar la tierra, minimizando el riesgo de lesiones y esfuerzo necesario. The object of the invention is to facilitate and reduce as much as possible the work to be done when carrying out the digging of the soil to till the earth, minimizing the risk of injuries and effort required.
ANTECEDENTES DE LA INVENCIÓN Como es sabido, en trabajos de jardinería y otros afines, el cavado del suelo o terreno se realiza mediante la utilización de una azada, lo que requiere que la persona que realiza el trabajo deba efectuarlo agachado, es decir doblada la columna hacia delante, lo que conlleva problemas lumbares, independientemente del esfuerzo físico elevado que es necesario realizar, ya que cuando se cava con una azada es necesario realizar movimientos bruscos de columna y de brazos que al cabo de un periodo de tiempo no largo se vuelven insoportables, además de que al realizarse los golpes de una forma irregular se gasta una gran cantidad de energía. BACKGROUND OF THE INVENTION As it is known, in landscaping and other related works, the digging of the soil or land is carried out by means of the use of a hoe, which requires that the person who performs the work must perform it crouched, that is to say bent the column forward, which entails lumbar problems, regardless of the high physical effort that is necessary to perform, since when digging with a hoe it is necessary to perform sudden movements of the spine and arms that after a long period of time become unbearable , in addition to the fact that the blows of an irregular form are carried out a large amount of energy is spent.
Otro inconveniente es que cuando se cava con una azada, la tierra que se mueve es pisada inmediatamente por la persona que realiza la operación, ensuciando el calzado con tierra, además de requerir el allanamiento de la zona pisada para eliminar las huellas. También hay que considerar que cuando se cava con azada, en aquellos lugares en que hay numerosas plantas alrededor resulta muy incómodo, porque se puede chocar con las ramas, independientemente de que se dejan espacios a los que no se puede acceder para labrar la tierra. En definitiva el cavar con azada es una tarea incómoda, de gran desgaste físico, y lo que es más importante, afecta a las lumbares hasta el punto de que a muchas personas les resulta imposible cavar con azada. Another drawback is that when digging with a hoe, the Earth that moves is immediately trodden by the person who performs the operation, dirtying the footwear with dirt, in addition to requiring the search of the trodden area to eliminate fingerprints. It should also be considered that when digging with hoe, in those places where there are numerous plants around it is very uncomfortable, because it can collide with the branches, regardless of the fact that there are spaces that cannot be accessed to work the land. In short, digging with hoe is an uncomfortable task, of great physical wear, and what is more important, affects the lumbar to the point that many people find it impossible to dig with hoe.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La herramienta que se preconiza es una herramienta cavadora que resuelve la problemática anteriormente expuesta, ya que puede llevar a cabo el cavado del terreno sin necesidad de que la persona que lo realiza tenga que agacharse. The tool that is recommended is a digger tool that solves the problem described above, since it can carry out the digging of the ground without the need for the person who performs it to have to bend down.
Mas concretamente, la herramienta cavadora de la invención se constituye mediante una horca de cuatro dientes metálicos, que pueden ser de hierro o acero, unidos a un travesaño común del que se proyecta un mástil o columna de notable altura rematado en forma de "T", con la especial particularidad de que del travesaño donde quedan solidarizados los dientes de la horca, emerge hacia atrás un soporte o plantilla sobre la que el pie del usuario podrá hacer presión para llevar a cabo el clavado de los dientes sobre el terreno. De una forma preferente los dientes serán de acero, tendrán una longitud de 30 cms., y presentarán una leve curvatura u ondulación superior, sujetos a una rama transversal central o soporte para presionar con los pies de aproximadamente 26x6 cms., presentando el mástil una longitud de 80 cms. y será preferentemente tubular, mientras que la rama superior y transversal de dicho mástil será de aproximadamente 75 cms., determinando en conjunto una herramienta a modo de horca mediante la que se puede efectuar el cavado del terreno sin grandes esfuerzos, sin necesidad de agacharse y de forma fácil, puesto que el cavado de los dientes se efectuará sin problemas, posibilitando el girar la herramienta, voltear el terreno y en definitiva labrar la tierra sin apenas gasto de energía, todo ello con incisiones en la tierra que se efectuarán de forma certera y precisa, y con la persona que lo realiza en posición totalmente erguida, es decir de pie. Por último decir que mediante esta herramienta y en virtud de los dientes de la horca, se podrá perforar la tierra en esa longitud suficiente para mover la tierra en jardines y lugares afines, aunque evidentemente tanto la longitud del mástil como de la rama transversal y superior del mismo, como la longitud de los dientes, podrá ser variable y adaptarse siempre en cada caso a las necesidades y requerimientos, altura, potencia o fuerza de la persona que vaya a utilizarla. More specifically, the digging tool of the invention is constituted by a gallows of four metal teeth, which can be of iron or steel, joined to a common crossbar from which a mast or column of remarkable height projected in the shape of a "T" is projected. , with the special feature that from the crossbar where the teeth of the gallows are joined, a support or template emerges back on which the user's foot can press to carry out the nailing of the teeth on the ground. Preferably, the teeth will be made of steel, will have a length of 30 cms., And will have a slight curvature or undulation, subject to a central transverse branch or support to press with the feet of approximately 26x6 cms., The mast presenting a length of 80 cms. and it will preferably be tubular, while the upper and transverse branch of said mast will be approximately 75 cms., together determining a jib-like tool by means of which the ground can be dug without great efforts, without bending down and in an easy way, since the digging of the teeth will be carried out without problems, making it possible to turn the tool, turn the ground and ultimately work the land without hardly any energy expenditure, all with incisions in the earth that will be made accurately and precise, and with the person who performs it in a totally upright position, that is, standing. Finally, say that by means of this tool and by virtue of the teeth of the gallows, the earth can be drilled in that length sufficient to move the earth in gardens and related places, although obviously both the length of the mast and the transverse and upper branch of the same, as the length of the teeth, can be variable and always adapt in each case to the needs and requirements, height, power or strength of the person who is going to use it.

As can be seen in the aforementioned figures, the digging tool of the invention includes a kind of gallows with four equal teeth (1), preferably made of steel and with its sharpened ends, joined by its opposite end to the aforementioned sharpened by a common crossbar. (2), thus forming the gallows in which the teeth (1) are equal, run parallel to each other and equidistant, and also have a slightly curved profile by way of posterior undulation.
Sobre la parte central del travesaño (2) de solidarización de los dientes (1) va montado un mástil (3), emergiendo verticalmente hacia arriba, y rematado en una rama transversal (4), siendo ésta y el mástil (3) preferentemente tubulares y constituidos en acero o cualquier otro material metálico apropiado. On the central part of the crossbar (2) for the solidarity of the teeth (1) a mast (3) is mounted, emerging vertically upwards, and topped on a transverse branch (4), this being and the mast (3) preferably tubular and constituted in steel or any other appropriate metallic material.
Dicha rama transversal (4) podrá estar obtenida en un material aislante o disponer de un recubrimiento aislante, en orden a evitar riesgo de accidentes ante el contacto con un cable eléctrico, pudiéndose obtener en plástico o madera. En cualquier caso sobre la parte posterior de la zona de intersección del mástil (3) con el travesaño (2) de la horca, se ha previsto un soporte (5) para apoyo del pie que está realizado el cavado del terreno mediante la herramienta descrita, de manera que sobre ese soporte (5) la persona puede realizar un empuje hacia abajo, para conseguir un mejor clavado de los dientes (1) en el terreno y llevar a cabo una fácil tarea de labrado del mismo. De esta forma, cualquier persona ya sea joven o mayor, puede realizar labores de cavado del terreno sin que la forma física de la persona que lo realiza sea un obstáculo, permitiendo además obtener un máximo rendimiento con el mínimo esfuerzo, mediante la utilización de la propia herramienta, permitiendo a gran número de personas el que su trabajo en jardinería y lugares afines pueda resultar mas agradable, ya que el clavado de los dientes (1) de la horca se efectuará fácilmente por empuje sobre el soporte (5) mediante el pie, permitiendo el giro de la herramienta hacia donde sea mas cómodo para llevar a cabo el volteo y labrado del terreno. Said transverse branch (4) may be obtained in an insulating material or have an insulating coating, in order to avoid the risk of accidents when in contact with an electric cable, which can be obtained in plastic or wood. In any case, on the back of the area of intersection of the mast (3) with the crossbar (2) of the gallows, a support (5) is provided for support of the foot that is done by digging the ground by means of the tool described , so that on that support (5) the person can perform a downward push, to achieve a better nailing of the teeth (1) in the ground and carry out an easy task of carving it. In this way, any person, whether young or old, can do the work of digging the land without the physical form of the person doing it being an obstacle, also allowing maximum performance with minimum effort, through the use of own tool, allowing a large number of people that their work in gardening and related places can be more pleasant, since the nailing of the teeth (1) of the gallows will be easily done by pushing on the support (5) by the foot , allowing the rotation of the tool to where it is most comfortable to carry out the turning and styling of the ground.
