  • the geometry is such that it can have multiple sides and edges so that it catches or meshes with a tool such as a turning tool which then allows the vented set screw to turn. The turning in of this vented set screw results in a selected positional setting for this set screw and consequently the fuse and the locking pin.

  • Set screw 122 further comprises an open channell22.1, wherein when the lock experiences an elevated temperature, such as during a fire, which can drive temperatures above 150 degrees, above 170 degrees or even above 180 or 190 degrees Fahrenheit, fusible block 125 melts, flowing into open channel 122.1 of set screw 122, causing locking pin 127 to move into channel 122.1 of set screw 122, releasing locking pin 127 and causing said actuator to act upon door leaf 104 to cause the door leaf 104 to close against jamb leaf 102.
  • an elevated temperature such as during a fire
  • fusible block 125 melts, flowing into open channel 122.1 of set screw 122, causing locking pin 127 to move into channel 122.1 of set screw 122, releasing locking pin 127 and causing said actuator to act upon door leaf 104 to cause the door leaf 104 to close against jamb leaf 102.
  • This actuator 111 can comprise a spring such as a torsion spring which can be wound in tension and then locked in place via the lock 119 to prevent the spring from rotating during normal state.
  • the actuator comprises a catchment ring 130 coupled to door leaf knuckle 112.
  • This catchment ring has a flange 132.
  • the first end section 146 is coupled to spring 144 and has a complementary flange 148.
  • 12B discloses another embodiment 220.2 which shows a face 224 and two holes 225.1 and 225.2 which form a channel to allow for the flow of the fusible block therein.
  • the flush surface 222 or the surface formed by block 224 as well as holes 225.1 and 225.2 are configured to provide more surface area so that the flow of the fusible block 125 is relatively slower than with the other embodiments disclosed above. This allows for a more resilient lock in the face of an elevated temperature.

Abstract

La présente invention concerne un mécanisme de fermeture pour une porte actionnée durant un incendie, ledit mécanisme entraînant la fermeture automatique de la porte. La présente invention propose une charnière qui comporte des plaques de charnière opposées, qui comprennent un battant à porte et un battant à cadre, chacun pivotant autour d'un axe de charnière et un ressort. Une bosse de ressort de charnière est ancrée à l'intérieur d'un canal qui comporte un bloc à fusible, qui empêche la bosse et une tension de ressort de se déplacer dans le canal. A une température prédéterminée, le bloc à fusible se rompt, entraînant le déplacement de la bosse de ressort et de la tension de ressort en prise avec la porte fixée au battant à porte de la charnière, entraînant ainsi la fermeture de la porte au moyen de l'énergie cinétique du ressort tendu.
