El paracaídas presenta en sentido coaxial con el bulón y tornillo una rueda que hace rodar al conjunto por el interior de la guía citada.The parachute presents coaxially with the bolt and screw a wheel that makes the assembly roll by the Inside of the cited guide.

El paracaídas presenta en su parte superior una polea en la que se fija el extremo del cable que va relacionado por el otro extremo con los contrapesos.The parachute presents in its upper part a pulley on which the end of the cable that is related by the other end with the counterweights.

El paracaídas comprende un bastidor fijo y un bastidor móvil.The parachute comprises a fixed frame and a mobile frame.

El bastidor fijo es en el que se monta el bulón y tornillo de fijación del mismo lateral del bastidor de la puerta y también se monta la rueda con su cojinete que se desplaza y guía la puerta por el interior de la guía solidaria al hueco de la puerta.The fixed frame is where the bolt is mounted and  fixing screw on the same side of the door frame and the wheel is also mounted with its bearing that moves and guides the door inside the guide integral to the hollow of the door.

El bastidor presenta en los laterales, respecto al eje de la guía citada, sendas escotaduras a través de las cuales salen sendas ruedas trinquete que se enclavan y presionan en contra los laterales interiores de la guía a través de la cual se desplaza el paracaídas.The frame presents on the sides, respect to the axis of the guide mentioned, paths recesses through which ratchet wheels come out that lock and press against the inner sides of the guide through which it travels the parachute.

Este enclavamiento tiene lugar cuando se rompe el cable y actúa libremente el peso de la puerta y un muelle del mecanismo que estaba comprimido se destensa desplazando el bastidor móvil.This interlocking takes place when the  cable and acts freely the weight of the door and a spring of the mechanism that was compressed stretches by displacing the frame mobile.

En este desplazamiento las ruedas que determinan los trinquetes, con sus tetones se desplazan por las aberturas rasgadas practicadas en el bastidor móvil lo que hace que dichas ruedas giren de modo excéntrico en el sentido de salida lateral o de enclavamiento. Por lo tanto este enclavamiento que se ve favorecido por el propio peso de la puerta actúa cuando el cable se rompe.In this displacement the wheels that determine the ratchets, with their teats move through the openings torn in the mobile frame which makes said wheels rotate eccentrically in the direction of lateral exit or interlocking Therefore this interlocking that looks favored by the weight of the door itself acts when the cable is break

Descripción de un ejemplo práctico de realización de la invenciónDescription of a practical example of realization of the invention

El paracaídas 1 es un freno en la caída de una puerta contrapesada, no representada en los dibujos.Parachute 1 is a brake in the fall of a counterbalanced door, not shown in the drawings.

El paracaídas 1 comprende un bastidor fijo 2 y un bastidor móvil 3.The parachute 1 comprises a fixed frame 2 and a  mobile frame 3.

El bastidor fijo 2 es central y se fija al bastidor de la puerta por medio de bulón y tornillo 4, en el lateral que se enfrenta la guía, no representada sujeta al hueco.The fixed frame 2 is central and fixed to the door frame by means of bolt and screw 4, in the side facing the guide, not shown subject to hole.

En el bulón o eje se monta una rueda 5 que hace rodar el conjunto del paracaídas por el interior de la guía, no representada.A wheel 5 is mounted on the pin or shaft roll the parachute assembly inside the guide, not represented.

El paracaídas presenta en un extremo de su bastidor móvil una polea 6 en la que se fija al extremo 1 correspondiente del cable, no representado, mientras que el otro extremo del cable se fija a los contrapesos, no representados.The parachute presents at one end of its mobile frame a pulley 6 in which it is fixed to end 1 corresponding cable, not shown, while the other Cable end is fixed to the counterweights, not shown.

Al encontrarse el cable haciendo fuerza hacia arriba el bastidor móvil 3 también se desplaza en el mismo sentido comprimiendo el muelle 7 contra el extremo 8 del bastidor fijo 2.When the cable is found making force towards above the mobile frame 3 also moves in the same direction compressing the spring 7 against the end 8 of the fixed frame 2.

En este caso las ruedas 9 tienen un giro excéntrico, hacia adentro del bastidor, a través de sus ejes 10, solidarios al bastidor fijo. Esta posición es 1 de puerta en uso.In this case the wheels 9 have a turn eccentric, inwards from the frame, through its axes 10, fixed to the fixed frame. This position is 1 door in use.

Estas ruedas tienen unos tetones 11 acoplados por sus extremos libres en escotaduras arqueadas 12 practicadas en el bastidor móvil 3, de modo que el desplazamiento de este bastidor hacia arriba produce que los tetones giren en el sentido de que las ruedas 9 se desplacen hacia el interior del paracaídas, no actuando como trinquetes.These wheels have 11 bolts coupled by  its free ends in arched recesses 12 practiced in the mobile frame 3, so that the displacement of this frame upwards causes the lugs to rotate in the sense that the wheels 9 move towards the inside of the parachute, not acting Like ratchets

Cuando el cable rompe, la única fuerza que actúa es la del propio peso de la puerta destensando el muelle 7 y arrastrando el bastidor móvil hasta que hace tope con el interior del bastidor fijo 2 pero en su movimiento los tetones 11 de las ruedas 9 se desplazan por las escotaduras rasgadas 12 en el sentido de que los trinquetes o ruedas 9 giran hacia fuera enclavándose en las ramas laterales de la guía sujeta a hueco de la puerta quedando frenada la puerta en su caída.When the cable breaks, the only force acting it is the weight of the door itself, distending the spring 7 and dragging the mobile frame until it stops inside of the fixed frame 2 but in its movement the lugs 11 of the wheels 9 move through the torn recesses 12 in the direction that the ratchets or wheels 9 rotate outward locking in the lateral branches of the guide attached to the door opening slowed the door in its fall.

Las ruedas 9 para hacer efecto de trinquete llevan en su superficie un dentado recto 13 que coopera en el anclaje correspondiente.The wheels 9 to make ratchet effect they carry on their surface a straight tooth 13 that cooperates in the corresponding anchor.
