Description

Dispositivo de seguridad para puertas de apertura rápida.Security device for opening doors fast

Objeto de la invenciónObject of the invention

La presente invención se refiere a un dispositivo de seguridad para puertas de apertura rápida del tipo de las que comprenden un marco perimetral y un eje motriz en el que se encuentra enrollada una lona o elemento laminar de cierre.The present invention relates to a device of security for doors of fast opening of the type of which they comprise a perimeter frame and a driving axis in which find a canvas or laminar closure element rolled up.

Antecedentes de la invenciónBackground of the invention

En la actualidad son conocidas las puertas de apertura rápida, que comprenden una lona o similar que se enrolla y desenrolla en un eje dispuesto en la parte superior del marco de la puerta. Estas puertas permiten una apertura y cierre rápido dada la velocidad de giro del eje y la ligereza de la puerta, siendo muy utilizada en almacenes y similares, ya que acoplados con sistemas de detección de presencia permiten automatizarlas.The doors of quick opening, comprising a canvas or the like that is rolled up and unwinds on an axis arranged at the top of the frame the door. These doors allow quick opening and closing given the speed of rotation of the axis and the lightness of the door, being widely used in warehouses and similar, since coupled with presence detection systems allow you to automate them.

Sin embargo existe el problema que cuando están abiertas, por avería o por mal regulación de giro, la puerta puede caer o cerrarse demasiado deprisa sobre la persona o vehículo que pasa por debajo del marco, ocasionando un accidente.However there is the problem that when they are open, due to breakdown or bad turn regulation, the door can falling or closing too fast on the person or vehicle that passes under the frame, causing an accident.

Descripción de la invenciónDescription of the invention

El dispositivo de seguridad de la presente invención permite el control y límite de la velocidad de giro de la puerta durante la operación de cierre.The security device of this invention allows the control and limit of the speed of rotation of the door during closing operation.

En efecto el dispositivo consiste en una estructura acoplable al eje ya conocido de enrollado de la lona de la puerta y que mediante al menos un cuerpo centrífugo acciona un actuador de freno o sistema de seguridad. Esta estructura está constituida por un cubo de acoplamiento con un chavetero de alojamiento de una chaveta y fijado mediante tornillo y por un disco, dispuesto en el plano perpendicular al eje.In effect the device consists of a structure attached to the already known axis of winding the canvas the door and that by means of at least one centrifugal body actuates a brake actuator or safety system. This structure is constituted by a coupling hub with a keyway of housing of a key and fixed by screw and by a disk, arranged in the plane perpendicular to the axis.

Sobre este disco se disponen unos cuerpos centrífugos o masas que con el giro del eje se desplazan hacia el exterior hasta accionar el actuador relacionado con el freno de la puerta o similar. El número de cuerpos centrífugos puede ser variable, aunque preferiblemente en un número de dos que limita el giro del eje fuera del límite permitido a media vuelta. Para mantener los cuerpos centrífugos fuera del rango de accionamiento del actuador, cada cuerpo está forzado en reposo mediante un muelle de pretensión. Cuando la velocidad de giro excede un límite prefijado, la fuerza centrífuga vence esta tensión y desplaza hacia el exterior dicho cuerpo hasta que acciona el actuador.On this disk some bodies are arranged centrifuges or masses that move with the axis rotation towards the outside until the actuator related to the brake of the door or similar. The number of centrifugal bodies can be variable, although preferably in a number of two that limits the shaft rotation outside the limit allowed at half a turn. For keep centrifugal bodies out of the operating range of the actuator, each body is forced at rest by means of a spring of pretense. When the turning speed exceeds a limit preset, the centrifugal force overcomes this tension and displaces said body outward until the actuator is operated.

Se ha previsto que el disco disponga, para cada cuerpo centrífugo, de un tope encargado de limitar su giro hacia la zona exterior. También se ha previsto que los cuerpos centrífugos estén dispuestos de forma que accionen el actuador en el sentido de giro correspondiente al desenrollado o caída de la puerta, que es el más peligroso en caso de que el mecanismo esté fuera de control. Para ello el cuerpo está dispuesto articulado por delante del pivote de giro propio en este sentido.The disk is planned to have, for each centrifugal body, of a stop responsible for limiting its turn towards the Outside area. It is also planned that centrifugal bodies are arranged so that they actuate the actuator in the direction of rotation corresponding to the unwind or fall of the door, which is the most dangerous in case the mechanism is out of control. For this the body is arranged articulated in front of the pivot pivot itself in this direction.

Realización preferente de la invenciónPreferred Embodiment of the Invention

Como se puede observar en las figuras referenciadas la nueva invención comprende un disco (1) provisto lateralmente de un cubo (2) con chavetero y tornillo (3) para su fijación al eje (11) de la puerta.As can be seen in the figures referenced the new invention comprises a disk (1) provided laterally of a hub (2) with keyway and screw (3) for its fixing to the axis (11) of the door.

Este disco (1) comprende en una cara lateral dos cuerpos (5) centrífugos, estando cada cuerpo (5) montado con posibilidad de giro sobre un pivote (4) solidario al disco (1) y orientado hacia el sentido de giro correspondiente al desenrollado de la puerta. Enfrentado al contorno del envolvente trazado por dicho cuerpo (5) en su giro se encuentra un actuador (8) de un sistema de freno o de parada de emergencia (no representado). Cada cuerpo (5) centrífugo presenta en su parte anterior un tope (6) emergente, enfrentado con un vástago (7) solidario al disco (1).This disc (1) comprises on one side face two centrifugal bodies (5), each body (5) being mounted with possibility of turning on a pivot (4) integral to the disk (1) and oriented towards the direction of rotation corresponding to the unwind of the door. Faced with the outline of the envelope drawn by said body (5) in its turn is an actuator (8) of a brake or emergency stop system (not shown). Each Centrifugal body (5) has a stop (6) emerging, faced with a rod (7) integral with the disc (1).

Sobre el pivote (4) de giro se encuentra montado un muelle (9) que actúa con sus extremos contra un anclaje (10) solidario al disco y contra la parte posterior del cuerpo (5), tendiendo a provocar el abatimiento del correspondiente cuerpo (5) hacia la zona interior del disco, de forma que durante el funcionamiento normal de la puerta se mantenga dentro del contorno del disco (1). Cuando el eje (11) gira a una velocidad excesivamente alta, los cuerpos (5) giran sobre los respectivos pivotes (4) por el efecto de la fuerza centrifuga, venciendo los respectivos muelles (9) y sobresaliendo parcialmente del contorno del disco (1) lo que provoca el accionamiento del actuador (8) de un sistema de freno o parada de emergencia propio de la puerta.On the pivot pivot (4) it is mounted a spring (9) acting with its ends against an anchor (10) solidarity with the disc and against the back of the body (5), tending to bring down the corresponding body (5) towards the inside of the disc, so that during the normal operation of the door remains within the contour of the disc (1). When the shaft (11) rotates at a speed excessively high, the bodies (5) rotate on the respective pivots (4) by the effect of centrifugal force, overcoming the respective springs (9) and partially protruding from the contour of the disc (1) which causes actuator actuation (8) of a brake system or emergency stop of the door.

Una vez descrita suficientemente la naturaleza de la invención, así como un ejemplo de realización preferente, se hace constar a los efectos oportunos que los materiales, forma, tamaño y disposición de los elementos descritos podrán ser modificados, siempre y cuando ello no suponga una alteración de las características esenciales de la invención que se reivindican a continuación.Once the nature of The invention, as well as a preferred embodiment, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
