Definitions

  • the present invention relates to a new pin for double-leaf fire doors designed with two objectives: to prevent the door from opening in the event of a fire, thus preserving the sealing of the enclosure against fire, and, at the same time, to allow the door to be opened quickly by the occupants of the enclosure in case of evacuation.
  • the invention technically falls within in the construction sector, in particular, the manufacture of double-leaf fire doors with a steel frame.
  • the factors that must be taken into account in the design of fire doors are basically: pressure, temperature and time. These three conditioning factors are what produce both deformations and dilations in this type of door.
  • the deformations depend on the type of material, the temperature and the dimension of the element subject to fire. These deformations are caused by buckling and torsion stresses, which cause warps and curvature in the door assembly.
  • the invention consists of an adjustable pin for double-leaf fire doors, designed with the intention of solving the problems posed: to ensure the closing of the door in case of fire; preserving the protected enclosure and the mechanical properties of the fire door and allowing, at the same time, the exit of the occupants out of the enclosure to a safe space, thus complying with the current regulations.
  • a tab is screwed to the side of the door lock, tab being a part made of metal with a Z-shaped section, while to the side of the counter-lock, a latch plate is screwed, this being a part made of metal with a meander-shaped section.
  • These parts are intended to be adjustable, so that they can be perfectly coupled to each other, thus avoiding possible failures in the installation. This adjusting is achieved thanks to the design of the sections of both parts. In this way, the pin will act when closing and opening the door, since the tab enters the latch plate upon closing and exits from it upon opening, eliminating the need to include any other accessory to the present invention.
  • the mechanism of action of the pin is very simple: when closing the door, the two parts engage fitting perfectly, but allowing sufficient play between them, so that, when the door is opened by the handle or the panic bar, they disengage without effort for the occupants of the premises who are attempting to exit.
  • the door leaves are allowed to open normally; an ordinary person would not notice the difference between the pin being placed or not, but in the event of fire, the invention acts as a safety mechanism while the door is closed, creating an additional lock that prevents the door from opening by the action of fire.
  • the tab which represents the main novelty of the invention, slides inside the latch part when the door opens and closes, without needing to install any other element, so that the installation time with respect to other solutions incorporating a rod, is shorter.
  • This invention also enhances the integrity of the door against fire, since, structurally, the pin becomes a point of constraint that allows rotation, but prevents vertical and horizontal displacements at that point, so that we are speaking of a structural support point. This means that in the event of a fire, the door at that point will provide greater resistance to deformation, specifically to buckling and torsion, and will tend to withstand the fire without opening for longer.
  • the invention is applicable to double-leaf fire doors with a steel frame, wherein the pin parts are fixed to the door in the central part, namely in the central side of each of the door leaves: primary (4) and secondary (1). It is foreseen that one or more pins may be screwed to the door leaves.
  • the pin will be coupled to them.
  • the latch part which is made of metal and has a meander-shaped section (2)
  • the tab which is made of metal and has a Z-shaped section (3) is screwed analogously at the homologous point of the primary door leaf (4).
  • the parts must be screwed through the pre-set holes (6) which allow the necessary vertical and horizontal adjustment, so that the parts couple perfectly: they must face each other in the central area of the door, so that when the two door leaves are closed, the parts couple, as the tab (3) will enter the latch part (2) naturally.
  • the latch part (2) acts as a counter-link, since its meander shape allows it to couple to the door leaf (4) leaving a clearance where the tab (3) can engage.
  • This tab (3) has been designed so that the folding of the Z-shaped section allows it to couple to the latch (2) and at the same time allows it to naturally separate when the door (1) is pushed.
  • a second optional embodiment of the invention is that instead of a latch part and a tab, two tabs with Z-shaped sections and made of metal (5) alike, are screwed to the primary (4) and secondary (1) door leaves by means of pre-set holes (6), which allow perfect vertical and horizontal adjustment of the parts.
  • a third optional embodiment of the invention is to screw to the secondary door leaf (1) a metal modified latch part (7) with a cut such as to allow a metal catch (8) fixed to the secondary door leaf (4) to engage thereon and, at the same time, naturally separates when the door (1) is pushed.
