La tenaza de Ia invención comprende una cabeza portamordazas, a cuya cabeza van articulados, por el lado opuesto al ocupado por las mordazas, una biela y un brazo recto, estando las articulaciones entre estos tres componentes definidos por dos ejes que son paralelos y simétricos respecto del plano transversal medio de Ia cabeza portamordazas.The pincer of the invention comprises a head holder, at whose head they are articulated, on the opposite side to that occupied by the jaws, a connecting rod and a straight arm, the joints being between these three components defined by two axes that are parallel and symmetrical with respect to of the middle transverse plane of the head holder.
El brazo recto incluye un tramo dentado, a partir de un punto próximo al de articulación a Ia cabeza portamordazas. El resto de este brazo, a partir del extremo opuesto, conforma una empuñadura. El tramo dentado define una cremallera en forma de dientes de sierra.The straight arm includes a serrated section, starting from a point close to the articulation to the head holder. The rest of this arm, from the opposite end, forms a handle. The toothed section defines a zipper in the form of saw teeth.
Entre Ia cabeza portamordazas y Ia biela va montado, alrededor del eje de articulación entre ambos componentes, un resorte que impulsa a dicha biela, por su extremo libre, hacia el tramo dentado del brazo recto. La biela apoya por su extremo libre sobre el tramo dentado del brazo recto, a través de medios de apoyo que encastran entre los dientes del tramo dentado, para definir un apoyo fijo de la biela, siendo seleccionable ei punto o zona αei tramo dentado sobre el que apoyan los medios de apoyo citados.Between the head holder and the connecting rod is mounted, around the axis of articulation between the two components, a spring that drives said connecting rod, at its free end, towards the serrated section of the straight arm. The connecting rod supports at its free end on the serrated section of the straight arm, through support means that fit between the teeth of the dentate section, to define a fixed support of the connecting rod, the point or zone αei toothed section being selectable on which the mentioned support means rest.
Los dientes de Ia cremallera o tramo dentado del brazo recto presentan una inclinación opuesta al sentido de apoyo de Ia biela' sobre dicho tramo dentado, para asegurar este apoyo.The teeth of the rack or toothed section of the straight arm have an inclination opposite to the direction of support of the connecting rod 'on said toothed section, to ensure this support.
La biela puede quedar rematada en su extremo libre en un diente, introducible y encastrable entre los dientes del tramo dentado del brazo recto, que constituye los medios de apoyo citados de Ia biela.The connecting rod can be finished off at its free end in a tooth, which can be inserted and recessed between the teeth of the toothed section of the straight arm, which constitutes the mentioned support means of the connecting rod.
Estos medios de apoyo pueden también consistir en un trinquete articulado al extremo de Ia biela, según un eje paralelo al de articulación de Ia biela con Ia cabeza de Ia herramienta, cuyo trinquete es encastrable entre los dientes del tramo dentado del brazo recto, sobre una zona seleccionable a Io largo de dicho tramo dentado. Este trinquete puede quedar alojado dentro de una abrazadera que rodea al tramo dentado del brazo recto, con libertad de deslizamiento a Io largo del mismo. La abrazadera va articulada también a Ia biela, preferentemente mediante el mismo eje de articulación del trinquete.These support means can also consist of a ratchet articulated at the end of the connecting rod, along an axis parallel to the articulation of the connecting rod with the head of the tool, whose ratchet is embedded between the teeth of the straight section of the straight arm, on a zone selectable along said toothed section. This ratchet can be housed inside a clamp that surrounds the serrated section of the straight arm, with freedom to slide along it. The clamp is also articulated to the connecting rod, preferably by the same axis of articulation of the ratchet.
Los ejes de articulación entre Ia cabeza portamordazas, el brazo recto y Ia biela, así como entre ésta y Ia abrazadera que desliza sobre el tramo dentado del brazo recto, se materializan por otros tantos pasadores introducidos y fijados a través de orificios enfrentables de los componentes que se articulan.The axes of articulation between the head holder, the straight arm and the connecting rod, as well as between it and the clamp that slides on the straight section of the straight arm, are materialized by as many pins introduced and fixed through facing holes of the components They articulate.

The chuck head 1, as can be seen better in Figures 4 and 5, is of approximately prismatic configuration, rectangular straight, and has a passage 20 that runs between two of its opposite faces, through which jaws 2 and 3 are mounted. Head 1 has a second passage 21, which runs between its two other side faces, in which the drive nut 4 is mounted, figure 1. In addition, the head 1 is provided with two pairs of lugs 22 and 23, with aligned holes, between which the extensions 13, of the straight arm are introduced 5, figure 2, and 17 of the connecting rod 6, figure 3, for the introduction of the pins that constitute the articulation axes 7 and 8.
Las mordazas 2 y 3, representadas en las figuras 6 a 9, incluyen un dentado 25 que queda enfrentado en las dos mordazas, según puede apreciarse en Ia figura 1. Estas dos mordazas disponen de sendos cuerpos rectos 26 y 27, que forman ángulo recto con Ia superficie del dentado 25 y que, según puede apreciarse en las figuras 7 y 9, son de sección transversal aproximadamente semicircular, quedando estos cuerpos enfrentados y adosados por las superficies planas en las que Ia mordaza 26 dispone de un nervio central longitudinal 28, mientras que el cuerpo 27 dispone de un canal central longitudinal 29 de igual sección, quedando el nervio 28 acoplado en el canal 29, al adosar los cuerpos 26 y 27, para definir medios de guía entre las dos mordazas.The jaws 2 and 3, represented in figures 6 to 9, include a tooth 25 that faces the two jaws, as can be seen in Figure 1. These two jaws have two straight bodies 26 and 27, which form a right angle with the surface of the teeth 25 and which, as can be seen in Figures 7 and 9, are of approximately semicircular cross-section, these bodies being faced and attached by the flat surfaces in which the jaw 26 has a longitudinal central rib 28, while the body 27 has a longitudinal central channel 29 of the same section, the nerve 28 being coupled in the channel 29, when the bodies 26 and 27 are attached, to define guide means between the two jaws.
La superficie exterior semicilíndrica de los cuerpos 26 y 27 presenta nervios oblicuos que determinan, al adosar los dos cuerpos, un hilo helicoidal de rosca 30, sobre el cual queda enroscada Ia tuerca de accionamiento 4, figura 1.The semi-cylindrical outer surface of the bodies 26 and 27 has oblique ribs that determine, when the two bodies are attached, a helical thread 30, on which the drive nut 4, figure 1, is screwed.
Con esta constitución, al girar Ia tuerca 4 en uno u otro sentido, se provoca el deslizamiento de los cuerpos 26 y 27 y con ello de las mordazas 2 y 3 en uno u otro sentido, para separarse o aproximarse entre sí. En las figuras 12 y 13 se representa en perfil Ia abrazadera 10, Ia cual adopta forma de horquilla dimensionada para poder disponerse alrededor del tramo dentado 9 del brazo 5, con posibilidad de desplazamiento a Io largo del mismo, quedando sus paredes rematadas en sendas alas 31 con orificios 31' enfrentados, que se adosan exteriormente sobre el ensanchamiento 18 de Ia biela 6, figura 3, con los orificios de unos y otros componentes enfrentados para introducir el pasador que configura el eje 12 de articulación, figura 1. Dentro de Ia abrazadera 10 va dispuesto el trinquete 11 , figuras 10 a 11, el cual incluye un nervio 32 con dentado frontal 33, con dientes de sierra que tiene inclinación opuesta a los dientes 15, figura 2, del tramo dentado 9 del brazo recto 5, para su encastre con los mismos. El nervio 32 se prolonga posteriormente en una orejeta 34 que está destinada a introducirse en Ia ranura 19 del ensanchamiento 18 de Ia biela 6, figura 3 y dispone de un orificio 35 a través del que se introducirá el mismo pasador que define el eje de articulación 12 entre biela 6 y abrazadera 10.With this constitution, turning the nut 4 in one or the other direction causes the sliding of the bodies 26 and 27 and with it the jaws 2 and 3 in one direction or another, to separate or approach each other. In figures 12 and 13, the clamp 10 is shown in profile, which takes the form of a fork sized to be able to be arranged around the toothed section 9 of the arm 5, with the possibility of moving along it, its walls being finished off on two wings 31 with holes 31 'facing each other, which are attached externally on the widening 18 of the connecting rod 6, figure 3, with the holes of some and other components facing to introduce the pin that configures the articulation axis 12, figure 1. Inside the clamp 10, the ratchet 11, figures 10 to 11, is arranged, which includes a rib 32 with a front teeth 33, with saw teeth having an inclination opposite to the teeth 15, figure 2, of the toothed section 9 of the straight arm 5, for its insertion with them. The rib 32 is subsequently extended in a lug 34 which is intended to be inserted in the groove 19 of the widening 18 of the connecting rod 6, Figure 3 and has a hole 35 through which the same pin that defines the articulation axis will be introduced 12 between connecting rod 6 and clamp 10.
La abrazadera 19, figura 13, y el trinquete 11 , figura 10, disponen de sendos orificios 36 y 37 enfrentables, a través de los que se introduce un pasador 38, figura 1 , para sujeción del trinquete, impidiendo el movimiento pendular del mismo al desembragar con el dentado 9.The clamp 19, figure 13, and the ratchet 11, figure 10, have two holes 36 and 37 facing each other, through which a pin 38, figure 1 is introduced, for securing the ratchet, preventing the pendulum movement thereof disengage with the teeth 9.
La biela 6 será de longitud menor que Ia distancia entre el eje de articulación 7 y el extremo más distante del tramo dentado 9.The connecting rod 6 will be of length less than the distance between the articulation axis 7 and the most distant end of the toothed section 9.
Para lograr Ia orientación de Ia cabeza 1 y con ello de las mordazas 2 y 3, será suficiente desplazar Ia abrazadera 10 a Io largo del tramo dentado 9, Io cual provocará el desplazamiento en igual sentido de Ia biela 6 que provocará el giro de Ia cabeza 1 alrededor del eje de articulación 8, pudiendo así lograr Ia orientación de Ia cabeza 1 y con ello de las mordazas 2 y 3.To achieve the orientation of the head 1 and with it of the jaws 2 and 3, it will be sufficient to move the clamp 10 along the toothed section 9, which will cause the displacement in the same direction of the connecting rod 6 that will cause the rotation of the head 1 around the axis of articulation 8, thus being able to achieve the orientation of the head 1 and with it of the jaws 2 and 3.
Para liberar el encastre del trinquete 11 en los dientes del tramo 9 y poder así desplazar Ia abrazadera 10 a Io largo de dicho tramo, será suficiente provocar una ligera basculación de Ia abrazadera 10 en el sentido de Ia flecha C de Ia figura 1 , por ejemplo actuando sobre Ia cabeza 1 , hasta lograr que los dientes del dentado 33 del trinquete 11 se desacoplen de los dientes del tramo dentado 9 del brazo recto 5, pudiendo así desplazar Ia abrazadera 10, junto con el trinquete 11, en cualquier sentido. Provocando Ia basculación de esta abrazadera en sentido opuesto al de Ia flecha C de Ia figura 1 , una vez lograda Ia orientación de Ia cabeza portamordazas 1 en el sentido y grado deseado, se logra el bloqueo entre trinquete 11 y brazo recto 1 , quedando así fijada Ia posición de Ia cabeza 1 , todo ello asegurado por el muelle 6', que garantizará en todo momento el acoplamiento del trinquete 11 sobre el dentado 9.To release the ratchet 11 in the teeth of section 9 and thus be able to move the clamp 10 along said section, it will be sufficient to cause a slight tilt of the clamp 10 in the direction of the arrow C of Figure 1, by example acting on the head 1, until the teeth of the teeth 33 of the ratchet 11 are disengaged from the teeth of the toothed section 9 of the straight arm 5, thus being able to move the clamp 10, together with the ratchet 11, in any direction. Causing the tilting of this clamp in the opposite direction to that of the arrow C of Figure 1, once the orientation of the head holder 1 in the desired direction and degree is achieved, the blockage between ratchet 11 and straight arm 1 is achieved, thus remaining fixed the position of the head 1, all secured by the spring 6 ', which will guarantee at all times the coupling of the ratchet 11 on the teeth 9.
En Ia figura 14 se muestra una variante de ejecución en Ia cual los medios de apoyo y encastre de Ia biela 6 sobre el tramo 9 dentado del brazo recto 5 consisten en una conformación en diente 40, en Ia que finaliza dicha biela en su extremo libre, diente que es encastrable entre los dientes 15 del tramo 9 dentado, para constituir el apoyo de Ia biela sobre el brazo recto. Por Io demás, Ia realización de Ia figura 14 es coincidente con Ia de Ia figura 1.Figure 14 shows an execution variant in which the support and insertion means of the connecting rod 6 on the serrated section 9 of the straight arm 5 consist of a tooth conformation 40, in which said connecting rod ends at its free end , a tooth that is embedded between the teeth 15 of the serrated section 9, to constitute the support of the connecting rod on the straight arm. Moreover, the embodiment of Figure 14 is coincident with that of Figure 1.
La constitución o configuración de las mordazas 2 y 3 puede variar, dependiendo de Ia aplicación de Ia herramienta. Así en las figuras 15 a 17 se muestran cabezas portamordazas que incluyen una mordaza 2' fija y una mordaza 3 deslizable, estando Ia mordaza fija 2' obtenida a partir de Ia propia cabeza portamordazas 1. En Ia figura 15 las mordazas presentan Ia configuración tradicional de una llave inglesa. En Ia figura 16 las mordazas adoptan una configuración de herramienta de apriete, tipo alicates. En Ia figura 17 Ia configuración de las mordazas es de una llave ajustable, con boca o ataque hexagonal, tipo llave de tubo o tomillería. Por último en Ia figura 18 se muestra un cabezal que tiene Ia mordaza 31 fija y Ia mordaza 2' articulada a Ia cabeza portamordazas 1 , según un eje 41 que es paralelo a los ejes 7 y 8 de articulación con Ia biela y brazo recto, respectivamente.The constitution or configuration of jaws 2 and 3 may vary, depending on the application of the tool. Thus, figures 15 to 17 show head holders that include a fixed jaw 2 'and a sliding jaw 3, the fixed jaw 2' being obtained from the head holder itself 1. In Figure 15 the jaws have the traditional configuration of a spanner In Figure 16 the jaws adopt a configuration of a tightening tool, pliers type. In Figure 17 the configuration of the jaws is of an adjustable wrench, with hexagonal mouth or attack, type pipe wrench or hardware. Finally, in figure 18 a head is shown that has the fixed jaw 3 1 and the jaw 2 'articulated to the head holder 1, according to an axis 41 that is parallel to the axes 7 and 8 of articulation with the connecting rod and straight arm respectively.
Los diferentes tipos de mordazas mostrados son solo ejemplos de las diferentes formas qué pueden ser aplicadas a Ia herramienta de Ia invención, con Ia biela 6 y brazo recto 5 articulados en Ia forma descrita a Ia cabeza 1 portamordazas, constituyendo dos palancas enfrentadas, para conformar una herramienta mas flexible y fácil de usar en espacios reducidos o de difícil acceso. The different types of jaws shown are only examples of the different forms that can be applied to the tool of the invention, with the connecting rod 6 and straight arm 5 articulated in the manner described to the head 1 carrier, constituting two facing levers, to conform a more flexible and easy-to-use tool in tight spaces or difficult to access.
