Abstract

Ergonomic handle for hand tools such as shovels and the like, which is characterized by having two grasping branches, the first branch (2) ending in a crutch-type handle (1) which embraces the forearm and which in turn is held by the hand of the same arm, and the second grip branch (11) in which engages the piece (3) which is extensible, adjustable in length sliding on the piece (11), ensuring the desired position with the pin (5) ensuring this pin with a pin (6) and hold this pin (5) with a chain (10) attached to the handle (3). The handle or grip branch (2) has an inclination towards the middle to facilitate the parallelism of the tool with respect to the ground. Between both branches, there is a joining piece (8) that serves as reinforcement. The shortest grip branch (11) is formed by three pieces (11), (3) and (4) and comes out about 40º from the grip branch (2) and towards the first handle (1), ending this branch (11), in a crosspiece or simple handle (4).

Description

Mango ergonómico para herramientas manuales.Ergonomic handle for hand tools.

Object of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un mango para distintos tipos de herramientas manuales, como: palas, rastrillos, azadas, raederas, horcas, etc... El cual ha sido concebido y realizado en orden a obtener numerosas y notables ventajas respecto a otros medios existentes de análogas finalidades.The present invention, as expressed in the set forth in this specification, refers to a handle for different types of hand tools, such as: shovels, rakes, hoes, rails, gallows, etc ... Which has been conceived and performed in order to obtain numerous and notable advantages over to other existing means of analogous purposes.

El mango está previsto para que al hacer los trabajos manuales con dichas herramientas, el operario no tenga que doblar y trabajar la espalda en infinidad de ocasiones, así como para trabajar con los brazos y no con la espalda con el beneficio que ello conlleva.The handle is provided so that when making the manual work with these tools, the operator does not have to fold and work your back on countless occasions, as well as to work with the arms and not with the back with the benefit That entails.

Pues bien, el dispositivo está basado en un mango donde en el extremo trasero va acoplada una agarradera (tipo muleta) que abraza el antebrazo y que a su vez es empuñada por la mano del mismo brazo. Además en el extremo delantero, en el final, junto a la herramienta elegida, sale un mango secundario, regulable en longitud, a mas o menos unos 40º, y en dirección a la primera agarradera, terminando este mango secundario en una agarradera simple para la segunda mano. Así mismo cabe la posibilidad de desmontar este segundo mango para trabajar con un solo brazo si fuese necesario.Well, the device is based on a handle where a handle is attached at the rear end (type crutch) that hugs the forearm and which in turn is wielded by the same arm hand. Also at the front end, at the end, next to the chosen tool, a secondary handle comes out, adjustable in length, about 40º, and in the direction of first handle, finishing this secondary handle in a Simple handle for the second hand. Also fits the possibility of disassembling this second handle to work with a Only arm if necessary.

Background of the invention

Se conocen unos cuantos útiles como el común (mango recto con agarre), desmontables, regulables en longitud, o fabricados en materiales mas o menos pesados.A few useful ones are known as the common (straight handle with grip), removable, adjustable in length, or made of more or less heavy materials.

El inconveniente de todos ellos es que para realizar el trabajo requerido, el operario tiene que tener la espalda doblada para poder coger de la base del mango para realizar la fuerza necesaria para manejar la herramienta, sobre todo si se trata de trabajos con pala, estirar y volver a doblar la espalda en infinidad de ocasiones con el consiguiente perjuicio que ello conlleva, (lesiones de espalda, menos rendimiento, bajas laborales etc...).The drawback of all of them is that for perform the required work, the operator must have the bent back to catch the base of the handle to perform the force necessary to handle the tool, especially if it's about shoveling, stretching and bending your back again in countless occasions with the consequent damage that it entails, (back injuries, less performance, sick leave etc...).

Description of the invention

El mango de la invención representa una nueva estructura en base a la cual se consigue que el desarrollo del trabajo se realice de un modo erguido, y que el trabajo lo realicen los brazos y no la espalda del operario. Para ello el mango está basado en dos agarraderas, la del primer brazo (tipo muleta), en la que apoya el antebrazo y que a su vez es empuñada por la mano del mismo brazo, pudiendo así empujar, tirar, levantar, girar, soportar la herramienta, incluso con solo un brazo, ya que hace el efecto de prolongación del propio brazo.The handle of the invention represents a new structure based on which the development of the work is done in an upright manner, and that the work be make the arms and not the back of the operator. For this the handle It is based on two handles, the first arm (crutch type), which supports the forearm and which in turn is held by the hand of the same arm, thus being able to push, pull, lift, turn, support the tool, even with just one arm, since it does the prolongation effect of the arm itself.

El mango principal lleva una pequeña curvatura hacia dentro para facilitar así el paralelismo de la herramienta respecto al suelo.The main handle has a small curvature inward to facilitate the parallelism of the tool With respect to the ground.

También posee en la parte final a la unión del mango a la herramienta un mango secundario que sale a mas o menos unos 40º en dirección a la primera agarradera siendo este el que se empuñaría con la segunda mano del operario ya que en su parte final va provisto de un agarre simple. Este segundo mango es regulable en longitud así como desmontable caso que se quiera trabajar con una sola mano.It also has in the final part the union of handle a secondary handle that comes out more or less about 40º in the direction of the first handle being this one would hold with the second hand of the operator since in its final part It is provided with a simple grip. This second handle is adjustable in length as well as detachable case you want to work with a single hand
