La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo de unión entre el mango y el cabezal intercambiable de una herramienta manual, previsto para su aplicación en cualquier tipo de mango y a cualquier tipo de herramienta manual. El objeto de la invención es conseguir una mayor facilidad, eficacia y seguridad en el enganche/desenganche del cabezal de la herramienta de que se trate y el correspondiente adaptador previsto en el mango de manejo de dicha herramienta. ANTECEDENTES DE LA INVENCIÓNThe present invention, as expressed in the statement of this specification, refers to a joining device between the handle and the interchangeable head of a hand tool, intended for application in any type of handle and to any type of hand tool. The object of the invention is to achieve greater ease, efficiency and safety in the engagement / disengagement of the head of the tool in question and the corresponding adapter provided in the handle of said tool. BACKGROUND OF THE INVENTION
Como es sabido, determinados tipos de herramientas son manejadas en su uso por un largo mango, de manera tal que éste suele incorporar en su extremo un adaptador con medios que posibilitan el enganche/desenganche del cabezal perteneciente a la herramienta, permitiendo que sobre un mismo mango puedan acoplarse y desacoplarse distintos tipos de herramientas, siempre que el cabezal de éstas incorporen el medio que permite establecer el enganche/desenganche respecto de los medios previstos en el adaptador establecido en el extremo del mango.As is known, certain types of tools are handled in use by a long handle, so that it usually incorporates at its end an adapter with means that allow the attachment / disengagement of the head belonging to the tool, allowing on the same different types of tools can be attached and uncoupled, provided that the head of the tools incorporates the means that allow the attachment / disengagement of the means provided in the adapter established at the end of the handle.
En tal sentido, es conocido un sistema que incluye un mango de aluminio que en su extremo incorpora interiormente un adaptador, acoplado a presión, y en cuyo adaptador se incluye una pieza en "U" con un pequeño tetón que es el encargado de establecer el enganche del cabezal de la herramienta, concretamente de una pletina montada axialmente en dicho cabezal, pletina que está afectada en proximidad a uno de sus extremos de una ventana en la que es enganchable el tetón de la pieza en "U" , cuando tal pletina se introduce axialmente por el extremo del adaptador montado íntegramente en el extremo del mango . Esa pieza de enganche en "U" , está asociada a un pulsador accionable externamente para desplazar ligeramente la pieza de enganche de forma transversal y liberar el tetón de tal pieza respecto de la ventana de la pletina del cabezal, efectuándose ese desplazamiento transversal de la pieza de enganche en contra de un muelle de compresión en espiral, situado entre tal pieza y la base o fondo del cajeado donde se ubica precisamente esa pieza de enganche, haciendo que el aludido muelle tienda a empujar constantemente la pieza de enganche hacia su posición operativa, en la que el pulsador queda ligeramente emergente hacia el exterior para poder realizar el pulsado correspondiente.In this sense, a system is known that includes an aluminum handle that at its end incorporates an adapter, snap-in, and whose adapter includes a "U" piece with a small stud that is responsible for establishing the coupling of the tool head, specifically of an axially mounted plate in said head, plate which is affected in proximity to one of its ends of a window in which the pin of the piece in "U" is hooked, when such a plate is introduced axially by the end of the adapter mounted completely in the end of the handle. This "U" hitch piece is associated with an externally operable push button to slightly displace the hitch piece transversely and release the bolt of such piece from the window of the head plate, making that transverse displacement of the piece of hitch against a spiral compression spring, located between such a piece and the base or bottom of the recess where precisely that hitch piece is located, causing the aforementioned spring tends to constantly push the hitch piece towards its operative position, in which the button is slightly popping outwards to perform the corresponding press.
Entre el cabezal de la pletina correspondiente a la herramienta y el extremo del adaptador acoplado interiormente en el mango, se ha previsto una pieza de goma montable/desmontable respecto del cabezal de la herramienta .Between the head of the plate corresponding to the tool and the end of the adapter coupled internally in the handle, a piece of mountable / removable rubber is provided with respect to the tool head.
El tipo de dispositivo que se acaba de referir presenta una serie de problemas e inconvenientes, entre los que se pueden citar los siguientes:The type of device just referred to presents a series of problems and disadvantages, among which the following can be mentioned:
Io.- El mango en el que se incluye el dispositivo, es triangular y de aluminio en toda su longitud, lo que supone un agarre no adecuado y un peso reducido que a veces no es el adecuado para conseguir un correcto y eficaz manejo de la herramienta, independientemente de que desde el punto de vista estético el aluminio no resulta apropiado. 2°.- El adaptador dotado de los medios de enganche para la herramienta, va montado en el interior del mango, por lo que en caso de que se quiera un desmontaje para cambiar cualquier elemento o pieza, se suelen presentar dificultades.I or .- The handle wherein the device is included, it is triangular and aluminum throughout its length, which is an unsuitable grip and low weight that sometimes is not suitable for a correct and efficient operation of the tool, regardless of the fact that from an aesthetic point of view aluminum is not appropriate. 2 .- The adapter equipped with the means of hook for the tool, is mounted inside the handle, so that in case you want a disassembly to change any element or piece, difficulties usually occur.
3o.- La configuración de la pieza de enganche y el posicionado del muelle de empuje de la misma, junto con la forma en espiral de tal muelle, crean problemas de funcionalidad, puesto que el muelle a veces se desubica, inutilizando ese sistema de enganche e impulsión del pulsador. Además, al ser dicha pieza de enganche en "U" y realizar el esfuerzo de presionado sobre una de las ramas laterales, puede producirse la rotura de tal rama teniendo en cuenta que la pieza es de plástico. 4 o.- La pieza de goma montada en el extremo del cabezal de la herramienta, al ser independizable puede perderse con facilidad y además pequeñas variaciones en su espesor hacen que el sistema no funcione bien; que el cabezal no enganche bien. DESCRIPCIÓN DE LA INVENCIÓN3 or .- The configuration of the insert and the positioning of the biasing spring thereof, along with the spiral shape of such a spring, create functionality issues, since the spring sometimes desubica, disabling the system hitch and push button drive. In addition, since said "U" hitch piece is made and the pressing effort is carried out on one of the lateral branches, the breaking of such a branch can take place taking into account that the piece is made of plastic. 4 or .- The rubber piece mounted at the end of the tool head, being independable can also easily be lost and small variations in thickness cause the system to malfunction; that the head does not engage well. DESCRIPTION OF THE INVENTION
El dispositivo objeto de la invención, basándose en el tipo referido con anterioridad, presenta una serie de innovaciones y mejoras que permiten solventar los problemas e inconvenientes que se acaban de mencionar y que presenta el citado dispositivo convencional.The device object of the invention, based on the type referred to above, presents a series of innovations and improvements that allow to solve the problems and inconveniences just mentioned and which the said conventional device presents.
En tal sentido, el dispositivo de la invención presenta como primera característica de novedad el hecho de que la pieza de enganche presenta una configuración en "U", pero donde el resalte o tetón de enganche para la pletina del cabezal de la herramienta está formado por un sector rectangular saliente de la zona central interna correspondiente a la rama intermedia de la pieza, proporcionando una mayor resistencia en el conjunto de tal pieza.In this sense, the device of the invention has as a first characteristic of novelty the fact that the coupling piece has a "U" configuration, but where the protrusion or coupling pin for the tool head plate is formed by a rectangular sector protruding from the internal central area corresponding to the intermediate branch of the piece, providing greater strength in the assembly of such a piece.
Además, esa pieza de enganche se relaciona con el pulsador a través de las ramas laterales de aquella, las cuales están afectadas de unas ventanas en las que se enclavan patillas elásticas pertenecientes al pulsador, teniendo éste forma de cajetín rectangular invertido, en dos de cuyas paredes están conformadas las patillas de anclaje en las ventanas de las ramas laterales de la pieza en "U" de enganche. Este sistema supone una disminución de esfuerzo, por no decir que éste resulta nulo, sobre la pieza de enganche, con lo que las posibilidades de rotura de la misma, son prácticamente nulas . Por otro lado, el muelle de impulsión de dicha pieza de enganche, es un fleje en arco que se posiciona sobre la superficie externa de la rama intermedia de la pieza en "U" de enganche, vinculándose hacia el fleje la pieza por medio de un pequeño tetón externo de ésta que ajusta en un orificio central del fleje, manteniendo a éste en su posición concreta de montaje, con lo que la funcionalidad del sistema de enganche/desenganche es fiable y sin problemas de desubicación.In addition, this hooking piece is related to the push-button through the lateral branches of that, which are affected by windows in which elastic pins belonging to the button are interlocked, this having the form of an inverted rectangular box, in two of whose walls are formed the anchor pins in the windows of the side branches of the piece in "U" hitch. This system supposes a decrease of effort, not to say that it is null, on the hitch piece, so that the chances of breaking it are practically nil. On the other hand, the driving spring of said coupling piece is an arc strap that is positioned on the outer surface of the intermediate branch of the "U" piece of engagement, the piece being connected to the strap by means of a Small external stud of this one that adjusts in a central hole of the strip, keeping to this in his concrete position of assembly, with what the functionality of the system of hook / unhook is reliable and without problems of relocation.
En cuanto al saliente de enganche de la pieza en "U", decir que el mismo presenta una rampa para deslizamiento de la pletina del cabezal de la herramienta, permitiendo una fácil operación de introducción y enganche de la pletina del cabezal de la herramienta, viéndose facilitado el guiado y deslizamiento de tal pletina hacia la posición de enganche, en virtud de unos bordes biselados con que está dotado el extremo de la referida pletina. Otra característica de novedad del dispositivo es que el mango está constituido preferentemente por un tramo tubular de aluminio y el resto por un cuerpo de madera acoplado sobre el extremo libre de dicho tramo de aluminio, constituyendo una prolongación axial de éste. Es decir, el mango es una combinación de aluminio y madera, lo cual resulta de aspecto estético más noble que los convencionales.As for the protrusion of the "U" piece, say that it has a ramp for sliding the tool head plate, allowing an easy operation of insertion and hooking of the tool head plate, looking facilitated the guidance and sliding of such a plate towards the position of engagement, by virtue of beveled edges with which the end of said plate is provided. Another novel feature of the device is that the handle is preferably constituted by an aluminum tubular section and the rest by a wooden body coupled on the free end of said aluminum section, constituting an axial extension thereof. That is, the handle is a combination of aluminum and wood, which results in a more noble aesthetic appearance than conventional ones.
Otra característica de novedad es que el adaptador que incorpora el dispositivo de enganche/desenganche, va montado externamente sobre el extremo del mango, lo que facilita el desmontaje de aquél para subsanar cualquier reparación, mal funcionamiento, etc.Another characteristic of novelty is that the adapter that incorporates the device of attachment / release, is mounted externally on the end of the handle, which facilitates the disassembly of the latter to correct any repair, malfunction, etc.
La pieza de goma que actúa como tope entre el cabezal y el adaptador prevista en los dispositivos convencionales, en el dispositivo de la invención es una parte inyectada en el propio adaptador, por lo que no es independízable, impidiendo con ello su posible pérdida. BREVE DESCRIPCIÓN DE LOS DIBUJOS Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva un juego de dibujos en base a los cuales se comprenderán más fácilmente las innovaciones y ventajas del dispositivo de unión entre el mango y el cabezal intercambiables de herramientas manuales, realizado de acuerdo con el objeto de la invención.The rubber part that acts as a stop between the head and the adapter provided in the conventional devices, in the device of the invention is a part injected into the adapter itself, so that it is not independent, thereby preventing its possible loss.
