Description

Deslizadera para cajones fuertemente cargados.Slide for drawers strongly loaded

Object of the invention

La presente invención se refiere a una deslizadera de las utilizadas para la apertura y cierre de cajones, donde el cajón descansa sobre dos deslizaderas laterales debidamente fijadas al cuerpo de un mueble.The present invention relates to a Slider used for opening and closing drawers, where the drawer rests on two side slides duly fixed to the body of a piece of furniture.

El objeto de la invención es conseguir una deslizadera de funcionamiento suave y silencioso, que resulta especialmente idónea para cajones que han de soportar fuertes cargas, con total extracción de los mismos.The object of the invention is to achieve a smooth and quiet running slider, resulting especially suitable for drawers that have to withstand strong loads, with total extraction thereof.

Background of the invention

Existen dispositivos de guiado y extracción de cajones del tipo anteriormente citado, pudiendo citarse entre otros los que muestran, por ejemplo, la EP-072082, la US-A3912341, o la WO-A94/26146.There are guidance and extraction devices for drawers of the aforementioned type, and may be cited among others those that show, for example, EP-072082, the US-A3912341, or WO-A94 / 26146.

Estos dispositivos de guiado, al igual que otros muchos, presentan como denominador común el hecho de que el deslizamiento entre las partes fija y móvil de la deslizadera se lleva a cabo con la colaboración de bolas, que por su configuración esférica determinan contactos puntuales entre las superficies que relacionan, lo que trae consigo que ante una carga excesiva las bolas tiendan a "clavarse" en los puntos de contacto, generando "surcos" en las guías con el paso del tiempo, que solo pueden ser evitados mediante la utilización de materiales de gran dureza, con la consecuente y negativa repercusión que esto supone a nivel de costos.These guiding devices, like others many present as common denominator the fact that the sliding between the fixed and mobile parts of the slider will carried out with the collaboration of balls, which by its configuration spherical determine point contacts between the surfaces that they relate, which brings with it that before an excessive load the balls tend to "stick" in the contact points, generating "grooves" in the guides over time, which can only be avoided by using high hardness materials, with the consequent and negative impact that this supposes at the level of costs.

Description of the invention

La deslizadera que la invención propone ha sido concebida y estructurada en orden a resolver de forma plenamente satisfactoria esta problemática, y se basa en la utilización de rodillos, en lugar de bolas, de manera que tales rodillos determinan apoyos lineales y no puntuales sobre las guías, o lo que es lo mismo, descargan la presión a lo largo de una ancha banda de rodadura, con lo que el desgaste es prácticamente nulo sin necesidad de materiales de especial dureza.The slide that the invention proposes has been conceived and structured in order to fully resolve satisfactory this problem, and is based on the use of rollers, instead of balls, so that such rollers determine linear and non-specific supports on the guides, or what it's the same, they discharge the pressure over a wide band of rolling, so wear is practically zero without need of materials of special hardness.

De acuerdo con otra de las características de la invención, los citados rodillos no giran sobre ejes sino que están alojados en una especie de "jaula", que permite su libre giro y que presenta ventanas a través de las que sobresalen los citados rodillos para poder contactar directamente sobre las guías.According to another of the characteristics of the invention, said rollers do not rotate on shafts but are housed in a kind of "cage", which allows its free spin and that presents windows through which the mentioned ones stand out rollers to be able to contact directly on the guides.

De forma mas concreta las citadas jaulas constituyen tanquetas en las que participan dos jaulas porta-rodillos, convenientemente distanciadas entre sí mediante brazos distanciadores, pudiendo no obstante participar mas de dos jaulas en una misma tanqueta.More specifically the cited cages they constitute tanks in which two cages participate roller holder, conveniently spaced between yes by means of distance arms, being able nevertheless to participate More than two cages in the same tank.

En cada jaula se establecen dos niveles superpuestos de rodillos, uno superior y otro inferior, destinados a adaptarse a un perfil guía de sección en cruz, situándose rodillos tanto a un lado como a otro de la rama transversal de dicho perfil, como a la cara superior y a la cara inferior de dicha rama.In each cage two levels are established overlapping rollers, one upper and one lower, intended to adapt to a cross section guide profile, positioning rollers both side and side of the cross branch of said profile, such as the upper face and the lower face of said branch.

Específicamente se ha previsto que el citado perfil sea en doble cruz, de manera que sobre la cruz superior se establece una tanqueta, mientras que sobre la inferior lo hace otra, quedando ambas tanquetas alojadas en el seno de sendos perfiles en "U", de embocadura estrangulada y de embocaduras enfrentadas, de los que el superior recibe y fija al cajón, mientras que el inferior descansa sobre un soporte convenientemente configurado para fijarse a la pared lateral del mueble.Specifically it is expected that the aforementioned profile is double cross, so that over the upper cross is set a tank, while on the bottom does another, leaving both tanks housed in each other "U", strangulated mouth and mouth profiles facing each other, from which the superior receives and sets the drawer, while the lower one rests on a support conveniently configured to be fixed to the side wall of the furniture.

Se consigue de esta manera y una vez fijada una adecuada longitud en las tanquetas, que el perfil en "U" superior pueda desplazarse frontalmente con respecto al perfil en "U" inferior, el fijo al mueble, en una magnitud prácticamente coincidente con su propia longitud, lo que permite una extracción total del cajón, en condiciones de gran resistencia al repartirse la carga sobre una pluralidad de juegos de rodillos sustancialmente distanciados.It is achieved in this way and once set a adequate length in the tanks, than the "U" profile upper can move frontally with respect to the profile in Lower "U", fixed to the furniture, in a magnitude practically coinciding with its own length, which allows an extraction total of the drawer, in conditions of great resistance when distributed loading on a plurality of substantially roller sets apart.

Solo resta señalar por último que en cada grupo de rodillos situados en cada jaula, además de los rodillos mayoritarios de eje horizontal, se ha previsto la participación de una pareja de rodillos de eje vertical, destinados a facilitar el deslizamiento de las tanquetas con respecto a las paredes laterales de los perfiles en "U" de embocadura estrangulada.It only remains to point out that in each group of rollers located in each cage, in addition to the rollers horizontal axis majorities, the participation of a pair of vertical axis rollers, intended to facilitate the sliding of the tanks with respect to the side walls of the "U" profiles of strangulated mouth.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la deslizadera que se preconiza está constituida a partir de un soporte (1), dotado de una rama vertical (2) de fijación a la pared lateral del mueble, a la altura adecuada y exigida por el cajón, a cuyo efecto cuenta con una pluralidad de orificios (3) para utilización selectiva y fijación de dicho soporte a la pared del mueble, y una rama horizontal (4) en la que se define una especie de acanaladura (5), orientada hacia arriba, en la queda encajado y fijado un perfil (6), en funciones de raíl, de sección en "U" con su embocadura estrangulada y orientada hacia arriba, raíl (6) en cuyo seno está destinada a desplazarse una torreta (7), constituida mediante dos jaulas extremas (8-8'), sustancialmente separadas mediante brazos distanciadores (9), albergando en su interior cada jaula (8-8') a una pluralidad de rodillos (10) que forman cuatro agrupaciones, dos superpuestas a otras dos y dos adyacentes a las otras dos, rodillos (10) de eje horizontal, que apoyan sobre la rama asimismo horizontal e inferior (11) de un perfil en doble cruz (12), como se observa especialmente en la figura
2.In view of the aforementioned figures, it can be seen how the slide that is recommended is constituted from a support (1), provided with a vertical branch (2) fixing to the side wall of the furniture, at the appropriate height and required by the drawer, for which purpose it has a plurality of holes (3) for selective use and fixing of said support to the wall of the furniture, and a horizontal branch (4) in which a groove type (5) is defined, oriented upwards, a profile (6), in the form of a rail, with a "U" section with its throttle and oriented upwards, rail (6) in whose breast is intended to move a turret (7) is fitted and fixed. ), constituted by two extreme cages (8-8 '), substantially separated by distance arms (9), housing inside each cage (8-8') to a plurality of rollers (10) that form four groups, two superimposed to two others and two adjacent to the other two, rodi The horizontal axis (10), which rest on the similarly horizontal and lower branch (11) of a double cross profile (12), as can be seen especially in the figure
2.

Por su parte la rama horizontal o transversal y superior (11') de dicho perfil en doble cruz (12), está destinada a recibir a los rodillos (10') de una segunda tanqueta (7') idéntica a la anterior, y a su vez alojada en el seno de un segundo perfil en "U" (6'), simétrico con respecto al perfil inferior (6), es decir de embocadura estrangulada y orientada hacia abajo, fijándose a su vez a la rama media y superior de este segundo perfil en "U" (6') el cuerpo del cajón.For its part the horizontal or transverse branch and upper (11 ') of said double cross profile (12), is intended for receive the rollers (10 ') of a second identical tank (7') to the previous one, and in turn housed within a second profile in "U" (6 '), symmetrical with respect to the lower profile (6), is say of strangulated mouth and oriented downwards, fixing turn to the middle and upper branch of this second profile in "U" (6 ') the body of the drawer.

Para evitar los posibles efectos de rodadura generados por una también posible tendencia del perfil en doble cruz (12) a bascular lateralmente conjuntamente con las tanquetas (7-7') montadas sobre el mismo, se ha previsto que en cada juego de rodillos y además de los rodillos (10) de eje horizontal anteriormente citados, se establezcan una pareja de rodillos (13) de eje vertical, que en su caso apoyarán sobre las paredes laterales de los perfiles en "U" (6-6').To avoid possible rolling effects generated by a possible double profile trend cross (12) to swing laterally together with the tanks (7-7 ') mounted on it, it is expected that in each set of rollers and in addition to the axle rollers (10) horizontal aforementioned, establish a pair of vertical axis rollers (13), which will be supported on the side walls of the "U" profiles (6-6 ').

Como se observa en el detalle ampliado de la figura 3 correspondiente a una de las tanquetas del dispositivo, las jaulas extremas (8-8') están dotadas de ventanas (14) a través de las que emergen al exterior los rodillos (10) y (13), para que éstos puedan contactar con el perfil en doble cruz (12), y complementariamente presentan en sus extremos aberturas (15), también de configuración en cruz, que permiten su deslizamiento con respecto al sector correspondiente del sector en doble cruz (12).As seen in the expanded detail of the Figure 3 corresponding to one of the tanks of the device, the extreme cages (8-8 ') are equipped with windows (14) through which the rollers emerge to the outside (10) and (13), so that they can contact the profile in double cross (12), and in addition they have openings at their ends (15), also in cross configuration, which allow its sliding with respect to the corresponding sector of the sector in double cross (12).

Por último se ha previsto que la deslizadera pueda incorporar, opcionalmente, la rueda de apoyo (16) mostrada en la figura 1.Finally, the slide is planned can optionally incorporate the support wheel (16) shown in Figure 1
