Description

Refuerzo para testeros de cajones de persiana.Drawer booster reinforcement of blind.

Object of the invention

La presente invención se refiere a un refuerzo especialmente concebido para testeros de cajones de persiana, concretamente establecido a nivel del vástago o pivote que constituye el medio de sustentación para el eje de arrollamiento de la persiana propiamente dicha.The present invention relates to a reinforcement specially designed for shutter drawers, specifically established at the level of the rod or pivot that it constitutes the means of support for the winding axis of the blind itself.

El objeto de la invención es conseguir en el testero un pivote notablemente rigidizado y con una escasa incidencia a nivel de costos.The object of the invention is to achieve in the testero a pivot remarkably stiffened and with a low incidence at cost level.

La invención resulta de especial aplicación en cajones de plástico para persianas de grandes dimensiones y, consecuentemente, de considerable peso.The invention is of special application in plastic drawers for large blinds and, consequently, of considerable weight.

Background of the invention

Como es sabido existen cajones para persianas enrollables que incorporan en sus extremos sendos testeros, dotados de medios de fijación a sus paredes longitudinales fijas, incorporando cada uno de dichos testeros, centradamente sobre el mismo, medios para montaje con posibilidad de giro de los extremos del eje de la persiana, concretamente en uno de tales extremos de la polea para accionamiento de la misma, y en el extremo opuesto de la complementaria contera.As is known there are drawers for blinds rollers that incorporate at their ends two heads, equipped with of fixing means to its fixed longitudinal walls, incorporating each of these testeros, centered on the same, mounting means with possibility of turning the ends of the axis of the blind, specifically at one such end of the pulley to drive it, and at the opposite end of the complementary count.

Tales medios para montaje con libertad de giro, consisten en ocasiones en un casquillo cilíndrico, monopieza con el propio testero, convenientemente centrado en el mismo, recibiendo dicho casquillo a un cojinete, y a través de él al eje de la persiana, mientras que en otras ocasiones la estructuración es contraria, es decir sobre el centro del testero se establece un pivote o tetón cilíndrico sobre el que a su vez se monta el eje de la persiana.Such means for mounting with freedom of rotation, sometimes consist of a cylindrical bushing, single piece with the own testator, conveniently focused on it, receiving said bushing to a bearing, and through it to the axis of the shutter, while on other occasions the structuring is contrary, that is to say on the center of the testator a pivot or cylindrical pin on which the shaft is mounted the blinds.

Por otro lado existen también cajones, y consecuentemente testeros, obtenidos en aluminio, que no ofrecen mayores problemas, mientras que los fabricados en material plástico y en el caso concreto los casos que incorporan el citado pivote o vástago cilíndrico, cuando el peso de la persiana es considerable existe un notable riesgo de que, con el uso, dicho pivote se rompa por su zona de unión a la placa constitutiva del testero.On the other hand there are also drawers, and consequently testeros, obtained in aluminum, that do not offer major problems, while those made of plastic material and in the specific case the cases that incorporate said pivot or cylindrical shank, when the weight of the blind is considerable there is a significant risk that, with use, said pivot will break by its zone of union to the constituent plate of the testero.

En orden a resolver este problema son conocidos testeros para cajones de persiana que, siendo mayoritariamente de plástico, presentan el citado pivote de naturaleza metálica, rematado por uno de sus extremos en una valona discoidal y laminar, de considerable amplitud, que queda embebida en el material plástico constitutivo del testero durante la fase de moldeo del mismo.In order to solve this problem they are known slats for blind drawers which, being mostly of plastic, present the aforementioned pivot of a metallic nature, topped by one of its ends in a discoidal and laminar wall, of considerable amplitude, which is embedded in the material constituent plastic of the tester during the molding phase of the same.

Esta solución presenta una problemática con una doble vertiente, por un lado el proceso constructivo del testero resulta considerablemente caro y por otro las capas de material plástico en las que queda embebida la citada valona discoidal son de muy reducido espesor, al verse éste limitado por la propia presencia de la valona metálica, con lo que el riesgo de rotura se sigue manteniendo, si bien no alcanza los niveles que en el caso de los pivotes de naturaleza plástica. Además se produce un mal acabado superficial del testero, ya que la presencia de la pieza metálica durante la fase de moldeo genera en el material plástico irregularidades mas o menos acusadas.This solution presents a problem with a double slope, on the one hand the construction process of the testero it is considerably expensive and on the other the layers of material plastic in which the cited discoidal wall is embedded are of very reduced thickness, when it is limited by the own presence of the metal wall, with which the risk of breakage is continues to maintain, although it does not reach the levels that in the case of the pivots of plastic nature. In addition there is a bad surface finish of the tester, since the presence of the piece metal during the molding phase generated in the plastic material roughly irregularities.

Description of the invention

El refuerzo para testeros que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, constituyendo una solución de gran solidez estructural y de bajo costo constructivo.The reinforcement for testeros that the invention proposes to solve the problem fully satisfactorily previously exposed, constituting a solution of great solidity Structural and low construction cost.

Para ello y de forma mas concreta la invención parte de un testero convencional de los provistos de un pivote de plástico, monopieza con el resto del testero, y afectado por un orificio axial y ciego, con el que se minimiza la cantidad de material que participa en dicho pivote, a la vez que se mejora la resistencia mecánica del mismo.For this and more specifically the invention part of a conventional tester of those provided with a pivot of plastic, monopieza with the rest of the testero, and affected by a axial and blind hole, which minimizes the amount of material that participates in said pivot, while improving the mechanical resistance thereof.

A partir de este testero básico y convencional, el refuerzo que la invención propone consiste en una pieza metálica a base de un disco de reducido espesor, del que emerge un vástago roscado, siendo la longitud y diámetro de dicho vástago roscado acordes con las del orificio ciego del pivote, orificio que en principio se prevé como ciego por cuanto que así es en los testeros convencionales por razones de estética, pero que igualmente podría no serlo por cuanto que para la implantación del refuerzo de la invención es imprescindible abrir dicho orificio ciego al exterior, para poder implantar desde aquí el vástago roscado participante en el refuerzo.From this basic and conventional testero, the reinforcement proposed by the invention consists of a metal part based on a disc of reduced thickness, from which a stem emerges threaded, the length and diameter of said threaded rod being according to those of the blind hole of the pivot, hole that in principle is foreseen as blind as it is in the front conventional for aesthetic reasons, but that could equally not to be so because for the implementation of the reinforcement of the invention is essential to open said blind hole to the outside, to be able to implant from here the threaded rod participating in the reinforcement.

Dicho vástago presenta un diámetro ligeramente sobredimensionado con respecto al del citado orificio, para que en su implantación se produzca un efecto de autorroscado del material plástico constitutivo del pivote, actuando tal disco que remata dicho vástago como tope limitador de penetración para la misma, en una maniobra de implantación tipo "tornillo", a cuyo efecto el disco incorpora centradamente, en correspondencia axial con el vástago roscado, un orificio ciego y poligonal para su accionamiento con una llave tipo "allen".Said rod has a diameter slightly oversized with respect to the aforementioned hole, so that in its implantation produces a self-tapping effect of the material constitutive pivot plastic, acting such a topping disk said rod as a penetration limit stop for it, in a "screw" type implantation maneuver, for which purpose the disc incorporates centrally, in axial correspondence with the threaded rod, a blind and polygonal hole for its drive with an "allen" type key.

La pieza metálica, como consecuencia de su notable diámetro, actúa también como tope sobre la cara externa del testero y tiende a impedir la basculación lateral del vástago metálico y consecuentemente la basculación del pivote plástico que podría provocar la rotura del mismo.The metal part, as a result of its remarkable diameter, also acts as a stop on the outer face of the tester and tends to prevent lateral tilting of the stem metallic and consequently the pivot of the plastic pivot that It could cause it to break.

Preferred Embodiment of the Invention

En las figuras reseñadas se ha representado un testero convencional (1) materializado en una placa rectangular, con sus correspondientes protuberancias perimetrales (2) en su cara interna, para acoplamiento machihembrado de las paredes longitudinales del cajón, y orificios (3) para fijación por atornillamiento, a la vez que en disposición centrada en su cara interna incorpora un pivote (4), monopieza, receptor con posibilidad de giro del eje de la persiana y dotado de un orificio axial (5) que por motivos de estética y tal como muestra la figura 1 es ciego, pero que podría estar abierto también hacia la cara externa del testero sin que ello afecte a la esencia de la invención, por cuanto que en cualquier caso dicho orificio debe ser finalmente abierto.In the figures outlined, a conventional tester (1) materialized on a rectangular plate, with its corresponding perimeter protrusions (2) on its face internal, for tongue and groove coupling of the walls longitudinal of the drawer, and holes (3) for fixing by screwing, while in disposition centered on your face internal incorporates a pivot (4), single piece, receiver with possibility of turning the axis of the blind and equipped with a hole axial (5) that for aesthetic reasons and as shown in the figure 1 is blind, but that could also be open towards the face external of the tester without affecting the essence of the invention, since in any case said hole must be finally open

El refuerzo en sí se materializa en una pieza metálica en la que participa un disco (6) de reducido diámetro y espesor, y un vástago roscado (7) que emerge perpendicular y centradamente del disco (6), al que solidamente unido, por ejemplo con carácter monopieza como cuando dicha pieza metálica está obtenida mediante moldeo por inyección a base de zamac, como se ha previsto preferentemente.The reinforcement itself materializes in one piece metal in which a disk (6) of reduced diameter participates and thickness, and a threaded rod (7) that emerges perpendicular and centered on the disk (6), to which it is solidly attached, for example as a single piece as when said metal part is obtained by injection molding based on zamac, as has been preferably planned.

El vástago roscado (7) es de longitud y diámetro acordes con las del orificio (5) del pivote (4), y mas concretamente con un sobredimensionamiento con respecto a éste último para que durante el montaje del accesorio de refuerzo se produzca un efecto de autorroscado de su vástago sobre la pared plástica del pivote, consiguiéndose de esta manera la fijación estable entre estos elementos.The threaded rod (7) is of length and diameter according to the hole (5) of the pivot (4), and more specifically with an oversize with respect to this last so that during the assembly of the reinforcement accessory produce a self-tapping effect of its stem on the wall plastic of the pivot, thus achieving fixation stable between these elements.

El disco (6) actúa tanto como tope limitador de penetración del vástago (7) en el orificio (5), como también como medio de rigidización que tiende a impedir la basculación lateral del vástago (7), contando en su extremo con un rehundido (8) para accionamiento del refuerzo con una llave allen.The disk (6) acts as a limit stop for penetration of the stem (7) into the hole (5), as well as stiffening medium that tends to prevent lateral tilting of the stem (7), counting at its end with a recess (8) to reinforcement drive with an Allen key.

El montaje de esta pieza metálica sobre el centro del testero reforzando el pivote (4) de éste último, asegura que el cajón pueda soportar persianas de considerable peso sin riesgo de rotura para dicho pivote.The assembly of this metal part on the center of the tester reinforcing the pivot (4) of the latter, ensures that the drawer can support blinds of considerable weight without risk of breakage for said pivot.
