Description

Pinza.Gripper.

Object of the invention

La presente invención se refiere a una pinza, especialmente concebida para la fijación de dos o más cuerpos laminares, como por ejemplo hojas de papel, obtenida con carácter monopieza a base de material plástico, en un proceso de inyección.The present invention relates to a clamp, specially designed for fixing two or more bodies laminar, such as sheets of paper, obtained with character single piece based on plastic material, in a process of injection.

El objeto de la invención es conseguir una pinza en la que, con una participación mínima de material, se consiga un efecto de apriete máximo en la mordaza definida por la misma y consecuentemente una óptima fijación de los elementos laminares de que se trate.The object of the invention is to achieve a clamp in which, with a minimum participation of material, a effect of maximum tightening on the jaw defined by it and consequently an optimal fixation of the laminar elements of in question

Background of the invention

Como es sabido, las pinzas convencionales están estructuradas mediante dos brazos relacionados entre sí por su zona media con la colaboración de un resorte que tiende a mantener dichos brazos cerrados el uno sobre el otro por uno de sus extremos, el correspondiente a la mordaza de la pinza, y separados por su extremo opuesto, el de accionamiento, actuando ambos brazos a modo de palanca de primer género. Evidentemente esta solución, con independencia de sus prestaciones funcionales, mejores o peores en función del diseño de la pinza, de la elasticidad del muelle, etc, resultan estructuralmente complejas y requieren de una operación de montaje entre sus diferentes elementos, que repercute de forma notable a nivel de costos.As is known, conventional clamps are structured by two interrelated arms by their area media with the collaboration of a spring that tends to keep said arms closed on each other by one of their ends, the corresponding to the clamp jaw, and separated at its opposite end, the drive, acting both arms as a lever of the first genre. Obviously this solution, regardless of their functional performance, better or worse depending on the design of the clamp, spring elasticity, etc., are structurally complex and require a assembly operation between its different elements, which affects notably at the cost level.

Tratando de minimizar este problema son conocidas pinzas en las que los dos brazos anteriormente citados se materializan en un cuerpo monopieza, obtenido mediante inyección a base de material plástico, de manera que cada pinza sale perfectamente acabada a término de la fase de moldeo de la misma, pero sin embargo las pinzas de este tipo conocidas hasta el momento presentan, en relación con la cantidad de material que participa en las mismas, un grado de elasticidad y presión en sus mordazas de cierre, que dejan mucho que desear.Trying to minimize this problem are known clamps in which the two arms mentioned above are they materialize in a single piece body, obtained by injection to plastic base, so that each clamp comes out perfectly finished at the end of the molding phase of it, but nevertheless the tweezers of this type known so far present, in relation to the amount of material participating in the same, a degree of elasticity and pressure in their jaws of Close, they leave a lot to be desired.

Description of the invention

La pinza que la invención propone ha sido concebida y estructurada en orden a conseguir, con unas reducidas dimensiones y una mínima participación de material en la misma, un alto grado de eficacia operativa y especialmente una elevada presión entre sus brazos a nivel de la mordaza de la misma.The clamp that the invention proposes has been conceived and structured in order to achieve, with reduced dimensions and a minimum participation of material in it, a high degree of operational efficiency and especially high pressure between your arms at the level of the jaw.

Para ello y de forma más concreta cada uno de los clásicos brazos que participan en la pinza presenta un tramo recto en uno de sus extremos, el correspondiente a la mordaza de cierre, con un dentado interior, un tramo intermedio curvo, de trayectoria aproximadamente semicircunferencial, de concavidad orientada hacia adentro, y un tercer tramo también recto, correspondiente a la extremidad de accionamiento de la pinza, con un estriado exterior para facilitar su agarre.To do this and more specifically each of the classic arms that participate in the clip presents a straight section at one of its ends, the one corresponding to the closing jaw, with an internal toothing, a curved intermediate section, trajectory approximately semicircunferential, with concavity oriented towards inside, and a third section also straight, corresponding to the clamp drive end, with an outer groove to facilitate your grip.

Estos dos brazos están relacionados entre sí mediante un núcleo interior que se sitúa en el área aproximadamente circular definida por los dos tramos intermedios y curvos de los brazos, materializándose este núcleo en un tabique acanalado, con un sector cilíndrico, que sobrepasa sustancialmente el semicilíndro, y que cuenta con dos prolongaciones paralelas que se unen por sus extremos opuestos al sector cilíndrico y al tramo recto y dentado interiormente de los respectivos brazos.These two arms are related to each other. by an inner core that is located in the area approximately circular defined by the two intermediate and curved sections of the arms, materializing this core in a ribbed partition, with a cylindrical sector, which substantially exceeds the semicilíndro, and that counts on two parallel extensions that are they join at their opposite ends to the cylindrical sector and the section straight and serrated internally of the respective arms.

La deformabilidad elástica de la pinza se centra fundamentalmente sobre dicho núcleo, a cuyo efecto cada brazo presenta su tramo recto y dentado interiormente relacionado con su tramo curvo, mediante una cartela exterior intermedia, de borde libre redondeado, mientras que los citados brazos se unen a su vez al núcleo central a través de tabiquillos que emergen radialmente de este último y que se fijan al sector curvo de dichos brazos relativamente cerca de su tramo recto y de accionamiento, tramo notablemente regruesado.The elastic deformability of the clamp is centered fundamentally on said core, for which purpose each arm presents its straight and indented section internally related to its curved section, by means of an intermediate outer edge border rounded free, while the aforementioned arms are joined in turn to the central nucleus through radially emerging partitions of the latter and that are fixed to the curved sector of said arms relatively close to its straight and drive section, section remarkably returned.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas y en especial de la figura 1, puede observarse como la pinza que la invención propone está constituida mediante dos brazos (1-1') unidos entre sí con carácter monopieza, como ya se ha dicho con anterioridad y como se verá más adelante, brazos en cada uno de los cuales se define un tramo recto (2), con su cara interna o de adaptación al otro brazo provista de un dentado (3), constituyendo este tramo recto (2) la mordaza o zona de cierre de la pinza, tramo recto que se prolonga sin solución de continuidad en un tramo curvo (4), de trayectoria aproximadamente semicircunferencial y de concavidad interior, rematado en otro tramo recto (5), correspondiente a la extremidad de accionamiento manual sobre la pinza y provisto en su cara externa de un estriado (6) para mejorar su agarre.In view of the figures outlined and especially of Figure 1, can be seen as the clamp that the invention proposes is constituted by two arms (1-1 ') united to each other with a single-person character, as has already been said with before and as will be seen later, arms in each of the which defines a straight section (2), with its internal face or adaptation to the other arm provided with a teeth (3), constituting this straight section (2) the clamp or clamp closure zone, section rectum that extends without continuity solution in a curved section (4), of approximately semicircumferential trajectory and of interior concavity, finished off in another straight section (5), corresponding to the manually operated tip on the clamp and provided on its outer face with a spline (6) to improve your grip

Ambos brazos (1-1') están relacionados entre sí con carácter monopieza mediante un núcleo (7) materializado en un tabique acanalado con un sector cilíndrico que se corresponde con la propia referencia (7) y que sobrepasa sustancialmente el semicilíndro, y dos prolongaciones paralelas (8) de dicho sector (7) que se unen respectivamente a los brazos (1) y (1'), concretamente en sus tramos curvos o intermedios (4), y más concretamente en las proximidades de dichos tramos (4) a los tramos (2) constitutivos de la mordaza, como también se observa en la figura 1.Both arms (1-1 ') are related to each other with a single piece by means of a core (7) materialized in a ribbed partition with a cylindrical sector that corresponds to the reference itself (7) and exceeds substantially the semi-cylinder, and two parallel extensions (8) of said sector (7) that respectively join the arms (1) and (1 '), specifically in its curved or intermediate sections (4), and more specifically in the vicinity of said sections (4) to the sections (2) constituents of the jaw, as also observed in the Figure 1.

La deformabilidad de los tramos rectos (2) correspondientes a la mordaza se ve prácticamente eliminada por la existencia de cartelas exterior (9) que, en correspondencia con el plano medio de la pinza, se extienden entre dichos tramos rectos (2) y la mitad proximal de los tramos curvos o intermedios (4), mientras que la deformabilidad de dichos tramos curvos (4) y de los tramos rectos (5) de accionamiento manual se ve a su vez limitada por la existencia de tabiquillos radiales (10) que relacionan cada brazo (1-1') con el núcleo (7) en zonas de los tramos curvos (4) próximas a los tramos rectos y de accionamiento manual (5).The deformability of the straight sections (2) corresponding to the jaw is virtually eliminated by the existence of external posters (9) which, in correspondence with the middle plane of the clamp, they extend between said straight sections (2) and the proximal half of the curved or intermediate sections (4), while the deformability of said curved sections (4) and of the straight sections (5) of manual actuation are in turn limited for the existence of radial partitions (10) that relate each arm (1-1 ') with the core (7) in areas of the curved sections (4) close to the straight and drive sections manual (5).

Como complemento de la estructura descrita se ha previsto que en una de las cartelas (9) exista un orificio pasante (11) que en determinadas aplicaciones prácticas de la pinza permite la identificación de la misma, por ejemplo con una etiqueta fijada a la pinza mediante una anilla o similar, mientras que uno de los tramos rectos (5) de accionamiento manual existe, en cada una de sus caras, un orificio ciego (12) que permite a su vez la fijación de un elemento tipo grapa o similar.As a complement to the structure described, provided that in one of the posters (9) there is a through hole (11) that in certain practical applications of the clamp allows the identification of it, for example with a tag attached to the clamp by means of a ring or similar, while one of the straight sections (5) of manual actuation exist, in each of their faces, a blind hole (12) that allows fixing of a staple or similar element.
