  • the invention further relates to a fire protection door or a door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extent, wherein in each case a first spring is arranged on the first end side and on the second end side, such in that the respective first spring engages in a first groove of a counter-configured door leaf element.
  • the invention also relates to a fire protection door or a door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extension, wherein in each case a first groove is arranged on the first end side and on the second end side, in such a way in that a first spring of a door leaf element designed in the same way engages in the respective first groove.
  • the door leaf elements have a first and a second end side along their longitudinal extent, wherein a first tongue and a second groove and the second end face a first groove and a second spring are arranged on the first end side.
  • the first spring engages in the first groove and the second spring engages in the second groove of an equivalent door leaf element.
  • the door leaf elements are pivotally connected to each other via hinges.
  • the closure device has two opposing blades, which are connected to each other via a hinge.
  • Each of the lamellae has a first end side and a second end side along its longitudinal extent, wherein a first spring is arranged on the first end side and a first groove on the second end side. The first spring engages in the first groove.
  • a further groove is introduced, wherein the further spring engages in the further groove.
  • the hinge has a first element and a second element.
  • the first element has a first groove, wherein a further spring is arranged on the base surface of the first groove.
  • the second element has a first spring and an additional groove formed on the end face of the first spring.
  • the first spring engages in the first groove and the other spring in the further groove.
  • the above-mentioned gates or doors are primarily sectional doors or sectional doors comprising a plurality of panels, wherein the panels are pivotally connected to one another via hinges or hinges.
  • sectional doors or sectional doors are not suitable to be used as fire protection sliding doors, as they do not withstand unilateral fire exposure for a long period of time, have insufficient gas tightness and also have a thermal bridge.
  • each door leaf element is connected to each other via tongue and groove connections to a gate or a door.
  • each door leaf element can be constructed identically and therefore have a spring on a first side and a groove on a second side.
  • Such a built fire protection sliding door is for example from the German utility model DE 86 05 369.2 U known.
  • the individual door leaf elements are formed from a thermally insulating material and are encased by a sheet metal shell. At the joints a tongue and groove connection is formed, so that the individual door leaf elements can be connected to a gate or a door connected in series.
  • Each shock is provided on both sides of the door leaf with a heat-insulating strip, which is firmly connected to each of the groove having door leaf element.
  • a disadvantage of this known design is that the joints represent a weak point for fire protection, since they are insufficiently tight for gases and liquids and also represent a thermal bridge. Thus, in a fire, heat is conducted via the joints from one side of the fire door to the other side. This effect is only insufficiently mitigated by the thermal insulation strips. These strips also provide a additional installation effort and complicate a recessed installation of the fire door.
  • a fire protection door or door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extent, wherein a first spring on the first end side and a first groove on the second end side is arranged wherein the first spring of a first door leaf element engages in the first groove of a similar second door leaf element, wherein on the base surface of the first groove another spring is arranged, wherein on the end face of the first spring, a further groove is arranged, wherein the further spring of the first Door leaf element engages in the further groove of the similar second door leaf element, and wherein the cross section of the first spring and / or the second spring in a wedge shape to the respective end face, or the cross section of the first groove and / or the other groove wedge-shaped to the respective base out rejuvenates that same like door leaf elements are held together by a wedge effect.

  • a first groove is arranged, wherein in the respective first groove of a first door leaf element engages a first spring of a counter-configured second door leaf element, wherein on the respective base of the first grooves each have a further spring is arranged, wherein the respective further spring of the first door leaf element engages in a further groove of the counter-configured second door leaf element, and wherein the cross section of the first spring and / or the second spring in a wedge shape to the respective end face, or the cross section of the first groove and / or the other groove wedge-shaped to the respective base out tapers that the counter-designed door leaf elements are held together by the wedge effect.
  • This configuration of the tongue and groove connection has the advantage that when nesting two adjacent door leaf elements results in a labyrinth-like seal, which is a major obstacle to the passage of gases and heat. Since the shock itself is already dense and insulating, can be dispensed with additional heat insulation strips. This results in a particularly simple construction of a fire door with a substantially smooth, flat surface.
  • a gate or door can be installed as a sliding door or sliding completely sunk in a wall opening.
  • the door leaf elements can be easily assembled via the tongue and groove joints. It can be formed with several standard door leaf elements gates and doors of any width. Due to the wedge effect a particularly good seal is achieved when pushing together two door leaf elements.

  • the outer contour can be formed, at least in some areas, from one or more composite, preferably two mirror-inverted, sheet metal shells.
  • the sheet metal shells have a good fire protection and are also easy to manufacture.
  • the sheet metal shells do not extend over the entire thickness of the door leaf element, so that in each case a first sheet metal shell is arranged on a first side surface of the door leaf element and a second sheet metal shell on a second side surface of the door leaf element and the sheet metal shells do not touch.
  • a first sheet metal shell is arranged on a first side surface of the door leaf element and a second sheet metal shell on a second side surface of the door leaf element and the sheet metal shells do not touch.

  • the first support roller has a profile which can transmit axial forces, so that the position of the first support roller is fixed in the direction of the axis, while the second support roller has a profile which can not transmit axial forces, so a shift of the second support roller in the direction of the axis is possible.
  • This makes it possible to set the position of the door or the door in a direction transverse to the center longitudinal plane exactly, but without running the risk that deteriorate the rolling properties.
  • Such a chassis guarantees easy mobility despite a precise positioning, which properties for a secure closing and a good seal are necessary.
  • the first support roller may have a substantially V-shaped or U-shaped, preferably inwardly curved, profile. In this way, a precise lateral positioning of the door leaf element is possible in a simple manner.

In this way, despite the presence of an end-side groove, a flush completion of the door or the door is given. Since this shaped body complements the profile, there is a massive conclusion of the door or the door, which opposes a high resistance from outside. Standard door leaf elements can also be used as the ultimate element.
  • the shaped body can be held by a sheet-metal profile, preferably a C-profile. This results in a particularly massive conclusion, which ensures the same good properties in terms of fire protection and resistance as on the side surfaces of the door leaf element on the front page.
