Description

Hebilla de cierre para flejes.Buckle strap closure.

Object of the invention

La presente invención se refiere a una hebilla que ha sido especialmente concebida como medio de cierre sobre sí mismo para un fleje, de los utilizados en el atado o embalaje de mercancías.The present invention relates to a buckle which has been specially conceived as a means of closing on itself same for a strapping, of those used in the tying or packing of goods.

El objeto de la invención es conseguir un sistema de cierre que permita un accionamiento manual sobre la hebilla y el fleje, en las manipulaciones de cierre de este último, en ausencia de las clásicas herramientas de tensado y ``mordido'' utilizadas en este ámbito, facilitando considerablemente las operaciones de atado y minimizando los costos de inversión al respecto.The object of the invention is to achieve a system of closing that allows a manual operation on the buckle and the strapping, in the closing manipulations of the latter, in the absence of the classic tensioning and `` biting '' tools used in this area, considerably facilitating the tying operations and minimizing investment costs in this regard.

Background of the invention

En el embalaje mediante flejes se utilizan habitualmente grapas metálicas, que requieren del concurso de herramientas y máquinas manuales que por un lado traccionan sobre los dos extremos del fleje, para tensarlo debidamente, y que por otro actúan sobre las grapas, troquelándolas y deformándolas, para que los dos sectores de flejes superpuestos queden inamoviblemente unidos entre sí.In packaging by strapping, they are used usually metal staples, which require the contest of hand tools and machines that on the one hand pull on the two ends of the strap, to tighten it properly, and that by other act on the staples, stamping and deforming them, to that the two sectors of overlapping strips remain immovably joined together.

Si bien esta solución cumple de forma plenamente satisfactoria los objetivos previstos para la misma, consiguiendo un alto grado de tensión para los flejes y una óptima fijación en el cierre de los mismos, en muchas ocasiones la inversión necesaria no está justificada, por el considerable costo de las máquinas o herramientas anteriormente citadas y por la no necesidad de un alto nivel de tensión en el fleje y una también alta resistencia en el cierre, como en los casos anteriormente citados de mercancías o material de poco peso, donde sería deseable un cierre más rápido y más sencillo de practicar.While this solution fully complies satisfactory objectives planned for it, getting a high degree of tension for the straps and optimal fixation in the closing them, in many cases the necessary investment is not is justified by the considerable cost of the machines or tools mentioned above and for the lack of a high tension level in the strap and also high resistance in the closure, as in the aforementioned cases of goods or light weight material, where faster closure would be desirable and Easier to practice

Description of the invention

La hebilla que la invención propone constituye la solución al problema anteriormente expuesto, de manera que en el ámbito de las mercancías con poco peso permite el tensionado y el cierre del fleje de forma manual, es decir en ausencia de máquinas o herramientas complementarias y con grados de tensión y sujeción sobradamente suficientes.The buckle that the invention proposes constitutes the solution to the problem described above, so that in the Lightweight merchandise scope allows for tensioning and strap closure manually, i.e. in the absence of machines or complementary tools with degrees of tension and support amply enough.

Para ello y de forma más concreta dicha hebilla se materializa en una chapa metálica, preferentemente de contorno rectangular, en la que en un proceso de troquelado se definen tres cortes en ``U'', en alineación longitudinal, a la vez que un perfil ligeramente sinusoidal para dicha chapa, determinando dos de los cortes anteriormente citados, contrapuestos, sendas aletas rectangulares, de borde libre ligeramente sobreelevado con respecto al cuerpo base de la chapa metálica, con la que definen estrechas ranuras destinadas al paso de los dos extremos del fleje, de manera que uno de dichos extremos se adapta a la cara externa de la doble aleta, tras sufrir dos acodamientos ortogonales y contrapuestos muy próximos que lo inmovilizan, mientras que el otro extremo, de mayor longitud, adopta una disposición sensiblemente simétrica con respecto al primero y, tras solaparse a este último, queda definitivamente fijado en la ranura definida entre la tercera aleta y el cuerpo base de la chapa, consiguiéndose así la estabilización definitiva del fleje.To do this and more specifically said buckle it is materialized in a metal sheet, preferably contour rectangular, in which in a die-cutting process three are defined `` U '' cuts, in longitudinal alignment, while a profile slightly sinusoidal for said sheet, determining two of the previously mentioned cuts, opposed, fins rectangular, free-edged slightly raised to the base body of the sheet metal, with which they define narrow slots intended for the passage of the two ends of the strap, so that one of said ends adapts to the outer face of the double fin, after suffering two orthogonal and very opposed contractions next that immobilize it, while the other end, of greater length, adopts a noticeably symmetrical arrangement with with respect to the first and, after overlapping the latter, it remains definitely fixed in the groove defined between the third fin and the base body of the sheet, thus achieving stabilization definitive of the strap.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la hebilla que la invención propone está constituida partir de una chapa metálica (1), de contorno rectangular, sensiblemente alargada, con un perfil (2) ligeramente sinuoso, y afectada por tres troquelados o cortes de configuración en ``U'', una pareja de cortes (3-3'), próximos, contrapuestos y enfrentados, y un tercer corte (4) sustancialmente más alejado de los anteriores, definiendo los dos primeros cortes (3-3') sendas aletas rectangulares (5-5'), que por su borde libre quedan sobreelevadas con respecto al cuerpo base (1), definiendo ranuras (6) que, desde la cara inferior de la hebilla, permiten el paso ajustado y a su través del fleje (7), uno de cuyos extremos pasa por la ranura (6) y se adapta a la cara superior o externa de las aletas (5-5'), como se observa perfectamente en la figura 3, mientras que la otra extremidad del fleje (7), más larga, pasa a través de la ranura (6'), definiendo también un doble escalonamiento ortogonal, se solapa al otro extremo del fleje y finalmente se introduce por la ranura (8) definida por el tercer corte en ``U'' (4), de manera que esta última ranura (8) estabiliza el extremo del fleje (7) del que se tracciona manualmente para su tensionado, extremo que a su vez estabiliza el otro extremo del fleje, el inicialmente acoplado a la hebilla y situado bajo él.In view of the figures outlined you can be observed as the buckle that the invention proposes is constituted from a metal sheet (1), contour rectangular, noticeably elongated, with a profile (2) slightly winding, and affected by three die cuts or configuration cuts in `` U '', a couple of cuts (3-3 '), coming, opposing and facing each other, and a third cut (4) substantially farther from the previous ones, defining the first two cuts (3-3 ') paths rectangular fins (5-5 '), which due to their free edge are raised with respect to the base body (1), defining grooves (6) that, from the lower face of the buckle, allow the tight passage and its through the strap (7), one of whose ends passes through the groove (6) and adapts to the upper or outer side of the fins (5-5 '), as seen perfectly in the figure 3, while the other end of the strap (7), longer, goes to through the groove (6 '), also defining a double orthogonal stepping, overlaps the other end of the strap and finally it is introduced by the slot (8) defined by the third `` U '' cut (4), so that this last groove (8) stabilizes the end of the strap (7) that is manually pulled for stressed, end that in turn stabilizes the other end of the strap, the one initially attached to the buckle and placed under it.

La hebilla ha sido concebida en principio para situarse sobre una de las caras del embalaje, pero siendo factible también su instalación sobre una de sus aristas, en cuyo caso es necesario alargar el cuerpo base (1) de la hebilla, distanciar convenientemente los cortes en ``U'' (3-3') y consecuentemente alargar sustancialmente los nexos (9) de unión de las aletas (5-5') al cuerpo base (1), como para que en esta zona la hebilla pueda sufrir un acodamiento ortogonal para una perfecta adaptación a dicha arista del embalaje.The buckle has been conceived in principle to be placed on one of the sides of the packaging, but being feasible also its installation on one of its edges, in which case it is necessary to lengthen the base body (1) of the buckle, distance conveniently the `` U '' cuts (3-3 ') and consequently substantially lengthening the connection links (9) of the fins (5-5 ') to the base body (1), so that in this area the buckle may suffer an orthogonal bending to a perfect adaptation to said edge of the packaging.
