WO2002080650A1 - Support with an axle for tilting digging tool - Google Patents

Abstract

Said support comprises a slanted tower, a shaft (or bars), a base/pedal and a sliding pawl. The slanted tower consists of two plates measuring 310 x 30 x 4 with a bore hole located on the upper part and centered on the three sides with an 8 m/ms diameter for said axle (or bars). Said plates are cut at an angle on the bottom side and are joined together by two reinforcements to brace them (by soldering). One of said reinforcements is located on the left side. It has a concave shape on the outer upper edge with the purpose of serving as a stop against the tool handle, measuring 43 x 30 x 4. The other plate is placed in a fully rectangular manner on the right side. Both plates are located at a corresponding distance from the base/pedestal (see drawing). The shaft (or bars) is/are located on the upper part of the slanted tower so that the tool handle may tilt during digging. The base/pedestal is formed by a plate with a trapezoid shape. The slanted tower is attached to said plate on the side and the edge and is centered in the upper face as shown in the drawing (by soldering). The sliding pawl has an angle measuring 100 x 35 x 15 m/ms. It is connected to the base/pedestal on the side opposite the slanted tower, on the lower face thereof at a distance of 25 m/ ms from the edge as shown in the drawing (by soldering). All parts are made of the same material (iron) with the exception of the shaft (or bars) that is/are made of steel. The inventiveness is based on the shaft (or bars) for tilting the tool and the sliding pawl. The invention can be used in gardens and makes it possible to dig with very little effort and without bending the vertebral column or the lumbar region due to the fact that the operation is carried out comfortably with the arms and foot.

SOPORTE CON EJE PARA LA BASCULACION DE LA HERRAMIENTA DE SHAFT SUPPORT FOR TILTING THE TOOL

CAVAR DESCRIPCIÓNCAVAR DESCRIPTION

El objeto de la presente invención es un soporte con eje que por su especial disposición facilita la realización de la penosa actividad de cavar, disminuyendo la fatiga y evitando dolores de espalda. Su utilización está indicada en aquellos trabajos que supongan cavar huertos y jardines, etc.The object of the present invention is an axle support that by its special arrangement facilitates the realization of the painful activity of digging, reducing fatigue and avoiding backaches. Its use is indicated in those works that involve digging orchards and gardens, etc.

Es conocido que la operación de cavar, tal como se realiza usualmente, es especialmente penosa. La razón estriba en los dos movimientos diferenciados que es preciso realizar, uno para clavar la herramienta en el terreno y otro para arrancar del mismo la tierra a separar. Si se utiliza ^*Una pala convencional, por ejemplo, será preciso en un primer movimiento hundirla en el terreno, muy probablemente apretando con el pie sobre su borde superior para, a continuación, doblar la espalda y voltear la pala para extraer la tierra de la excavación.It is known that the digging operation, as is usually done, is especially painful. The reason lies in the two differentiated movements that must be carried out, one to drive the tool into the ground and the other to tear the ground to be separated from it. If used ^* A conventional shovel, for example, it will be necessary in a first movement to sink it into the ground, most likely by pressing with the foot on its upper edge, then bending the back and turning the shovel to extract the earth from the excavation.

El soporte con eje objeto de la presente invención permite sustituir las penosas operaciones que se acaban de describir por otras mucho más simples y ligeras, facilitando grandemente la operación de cavar.The support with axis object of the present invention allows replacing the painful operations just described by others much simpler and lighter, greatly facilitating the operation of digging.

Para conseguirlo, el soporte con eje objeto de la presente invención se configura como un utensilio adaptable a cualquier mango de herramienta de cavar provisto de una articulación, consistente en dos montantes que descienden oblicuamente hasta unirse con una base plana, cuya cara inferior presenta una uña antideslizante paralela al eje de articulación. De esta forma se puede hacer sin gran esfuerzo presionando con el pie sobre la base plana para conseguir incrustar en el terreno la uña antideslizante, momento en el que el utensilio hincable con su mango pueden ser basculados sobre el eje del soporte para extraer la tierra de la excavación.To achieve this, the shaft support object of the present invention is configured as a tool adaptable to any digging tool handle provided with a joint, consisting of two uprights that descend obliquely until joining with a flat base, whose bottom face has a nail Non-slip parallel to the axis of articulation. In this way it can be done without great effort by pressing with the foot on the flat base to get the non-slip nail embedded in the ground, at which time the inflatable tool with its handle can be tilted on the axis of the support to extract the earth from the excavation.

En consecuencia, no es necesario realizar un esfuerzo especial ni doblar la espalda forzando la región lumbar, ya que todo el trabajo se realiza con los brazos y un pie.Consequently, it is not necessary to make a special effort or bend the back forcing the lumbar region, since all the work is done with the arms and one foot.

Para complementar la descripción que antecede y con objeto de ayudar a una mejor comprensión de las características de la invención, se va a realizar una descripción detallada de una realización preferida, en base a un juego de dibujos que se acompañan a esta memoria descriptiva y en donde, con carácter meramente orientativo y no limitativo, se ha representado lo siguiente:To complement the foregoing description and in order to help a better understanding of the features of the invention, a detailed description of a preferred embodiment will be made, based on a set of drawings that accompany this specification and in where, with a purely indicative and non-limiting nature, the following has been represented:

Como puede verse en las figuras 1 y 2 se presenta un utensilio hincable (7) que se prolonga en un mango ^"(8) sobre el que se dispone una articulación (1). De esta salen oblicuamente hacia abajo dos montantes (2), uno a cada lado del mango (8), unidos entre sí mediante un refuerzo superior (3) y un refuerzo inferior (4), terminando ambos montantes (2) en una base (5), plana, cuya cara inferior presenta una uña antideslizante (6) que corre paralela al eje de articulación (1).As can be seen in figures 1 and 2, an inflatable utensil (7) is presented which extends into a handle ^" (8) on which an articulation (1) is arranged. From this, two uprights (2) are obliquely lowered, one on each side of the handle (8), joined together by an upper reinforcement (3) and a lower reinforcement (4), ending both uprights (2) on a flat base (5), whose lower face has a non-slip nail (6) that runs parallel to the axis of articulation (1).

Para facilitar la penetración del utensilio hincable (7) en el terreno (9) el operario apoya con el pie sobre la herramienta, por lo que está previsto que el mango (8) descanse contra un apoyo (3') que presenta el refuerzo superior (3) y que se configura como una simple deformación de aspecto semicilíndrico. Una vez conseguido que el utensilio hincable (7) y la uña antideslizante (6) hayan penetrado en el terreno, se actuará sobre la parte superior del mango (8) para conseguir su basculamiento alrededor de la articulación (1) con lo que se extraerá la tierra excavada de la zanja (10).To facilitate the penetration of the inflatable tool (7) in the ground (9), the operator rests with the foot on the tool, so it is provided that the handle (8) rests against a support (3 ') that has the upper reinforcement (3) and that is configured as a simple deformation of semi-cylindrical aspect. Once the inflatable tool (7) and the non-slip nail (6) have penetrated the ground, the upper part of the handle (8) will be acted to achieve its tilting around the joint (1), which will be removed the excavated earth of the ditch (10).

Serán evidentes para un experto en la materia una serie de modificaciones y alternativas que, dentro de la esencialidad de la invención permitan adaptar la herramienta para cavar descrita a determinados trabajos específicos. Así, el utensilio hincable (7) puede adoptar muy diversas formas, reproduciendo los distintos aperos de jardín o las diferentes herramientas como palas, horcas, layas, etc. , mientras que el sistema de anclaje al suelo puede ser mediante una uña antideslizante (6) transversal tal como se ha descrito, pero pudiera consistir igualmente en una pluralidad de púas dispuestas en la cara inferior de la base (5) o cualquier otro sistema equivalente. Por su parte la articulación (1) puede estar constituida por un simple bulón pasante que abrace al mango (8) y a los montantes (2) o cualquier otro sistema abisagrado, y el apoyo (3') del refuerzo superior puede incorporar un amortiguador elástico y realizarse de múltiples maneras alternativas. A series of modifications and alternatives will be apparent to one skilled in the art, which, within the essentiality of the invention, allows the described digging tool to be adapted to certain specific works. Thus, the inflatable utensil (7) can take many different forms, reproducing the different garden implements or the different tools such as shovels, gallows, layas, etc. , while the ground anchor system can be by means of a non-slip nail (6) transverse as described, but could also consist of a plurality of barbs arranged on the underside of the base (5) or any other equivalent system. For its part, the joint (1) can be constituted by a simple through bolt that hugs the handle (8) and the uprights (2) or any other hinged system, and the support (3 ') of the upper reinforcement can incorporate an elastic shock absorber and be done in multiple alternative ways.
