Description

Puerta para ascensores o montacargas con paneles corredizos.Door for elevators or forklifts with panels sliding.

La presente invención se refiere a una puerta para ascensores o montacargas con paneles corredizos.The present invention relates to a door for elevators or forklifts with sliding panels.

Las puertas con paneles corredizos, con apertura central o telescópica, normalmente están provistas de un patín inferior que se desliza dentro de una guía dispuesta en el umbral de la puerta. Ello es válido sea para puertas con apertura lineal, sea para puertas con apertura circular, es decir aquellas cuyo umbral está constituido por una corona circular.Doors with sliding panels, with opening central or telescopic, they are usually provided with a skate bottom that slides into a guide arranged at the threshold of the door. This is valid either for doors with linear opening, or for doors with circular opening, ie those whose threshold It consists of a circular crown.

La presencia del patín de deslizamiento en el umbral es necesaria por razones de seguridad, para impedir que se produzcan roturas o torceduras de los paneles y, además, para garantizar precisión durante el recorrido de apertura y cierre de los mismos paneles.The presence of the sliding skate in the threshold is necessary for security reasons, to prevent it from produce breakage or twisting of the panels and, in addition, to ensure accuracy during the opening and closing path of The same panels.

Una desventaja de tal solución está representada por el hecho que el umbral, acanalado para alojar los patines, es un receptáculo de suciedad y residuos en general (por ejemplo, colillas de cigarrillos, envolturas de golosinas, etc.), no fáciles de quitar y que incluso pueden obstaculizar los normales movimientos de apertura y cierre de los paneles.A disadvantage of such a solution is represented due to the fact that the threshold, ribbed to house the skates, is a dirt and waste receptacle in general (for example, cigarette butts of cigarettes, candy wrappers, etc.), not easy to remove and that can even hinder the normal movements of opening and closing of the panels.

En el caso de montacargas de centros comerciales u hospitales, la acanaladura puede representar un obstáculo para las ruedas de los carritos y las ruedas de las sillas para lisiados.In the case of shopping malls or hospitals, the groove can represent an obstacle for cart wheels and wheelchair chairs for disabled people.

Además, incluso desde un punto de vista estético, como consecuencia del uso el umbral, con el pasar del tiempo, tiende a oscurecerse y ensuciarse en la acanaladura.In addition, even from a point of view aesthetic, as a consequence of using the threshold, with the passing of time, tends to get dark and get dirty in the groove.

La patente de invención DE 19.943.108 publica un dispositivo de guía y deslizamiento para la parte inferior de puertas (10, 12) de cabinas de montacargas que presenta correderas (34) soportadas sobre un marco (40) configurado substancialmente en U que se extiende hacia abajo desde la parte inferior del umbral (18) y el cual está vinculado a la puerta (10). Las correderas (34) son guiadas a lo largo de un asiento en sección (36) fijado o integrado en la parte frontal inferior no expuesta del umbral (18). Para cooperar con los canales guía (26, 32) colocados en la puerta (12), en la puerta (10) y en la superficie superior del umbral (18) se pueden proporcionar otras correderas (24, 28). En dicho documento el marco configurado en U está a la vista y se desliza dentro de una acanaladura definida en la parte frontal del umbral.The invention patent DE 19.943.108 publishes a guide and slide device for the bottom of doors (10, 12) of forklift cabins that have slides (34) supported on a frame (40) configured substantially in U extending down from the bottom of the threshold (18) and which is linked to the door (10). The sliders (34) are guided along a fixed sectional seat (36) or integrated in the lower exposed front part of the threshold (18). To cooperate with the guide channels (26, 32) placed in the door (12), on the door (10) and on the upper surface of the threshold (18) other slides can be provided (24, 28). In that document the U-shaped frame is visible and slides into a groove defined on the front of the threshold.

El objetivo de la presente invención es poner a disposición una puerta en la cual no haya necesidad de realizar una limpieza frecuente y dificultosa del
umbral.The objective of the present invention is to make available a door in which there is no need for frequent and difficult cleaning of the
threshold.

Otro objetivo de la presente invención es el de obtener lo anterior de manera sumamente simple y económica sin aumentar el volumen fuera del umbral.Another objective of the present invention is that of obtain the above in a very simple and economical way without Increase the volume outside the threshold.

Dichos objetivos se logran en su totalidad mediante la puerta de la presente invención, la cual está caracterizada por el contenido de las reivindicaciones expuestas abajo.These objectives are fully achieved. through the door of the present invention, which is characterized by the content of the claims set forth down.

En el caso de puertas lineales, la guía es una guía lineal rectilínea externa al umbral, mientras que en el caso de puertas con apertura circular la guía es una guía con forma de corona circular, externa al umbral.In the case of linear doors, the guide is a linear linear guide external to the threshold, while in the case of doors with circular opening the guide is a guide shaped circular crown, external to the threshold.
