Definitions

  • Seals of this type are used to seal gaps in doors or windows.
  • the seal is usually mounted at the lower end of the wing or, more rarely, at the upper end of the wing. Very often the seal is mounted in a groove that is provided at the lower end or upper end of the door leaf.
  • mount the seal on an outside of the sash, especially on glass doors or if the door or window is subsequently equipped with a seal.
  • seals serve to seal gaps between the sides of the sash and a frame.
  • the holder is usually a housing that is usually made of an aluminum or plastic profile. But there are also other holders that are connected to the sealing strip through the movement mechanism.
  • the holder can be attached to the sash or, if necessary, to the frame using mounting brackets and screws or other suitable elements.
  • the person skilled in the art is aware of various solutions from the prior art.
  • the mounting brackets can be inserted into the side of the holder.
  • the movement mechanism can be a leaf spring or scissor element mechanism. But other movement mechanisms are also known.
  • the seal then takes effect when the door or window is closed.
  • the trigger of a seal attached to the wing strikes the frame. If the seal is attached to the frame, the wing hits the trigger. The The force introduced into the trigger when it strikes is transferred to the movement mechanism, which is then actuated and moves the sealing strip from the release position into the sealing position.
  • the seal is used to prevent smoke from coming through the door or window in the event of a fire. Further, it may be desirable to have a door or window to prevent air from being drawn through a gap in the door or window, which will further fan the fire.
  • the trigger In the sealing position of the sealing strip, the trigger is normally actuated and pressed in, whereby the force necessary for the movement of the seal is introduced into the seal.
  • the trigger rests on the frame (or possibly on the sash), which means that the force necessary to maintain the sealing position is maintained to overcome the restoring force of the restoring spring. It has been shown that in the event of fires, the geometry of the door or window can change due to the heating of the frame and/or the sash and/or the parts of the seal. between the point at which the trigger is normally in the triggered state, i.e. in the sealing position of the sealing strip, and the point at which the frame (or sash) of the door or window is normally in the triggered state, can be form a distance.
  • This distance can result in no force or only a lower force than normal being introduced into the trigger without heating due to the fire.
  • the force introduced into the trigger to actuate the seal is eliminated or is therefore smaller than normal.
  • the movement mechanism then moves the sealing strip into the release position or at least in the direction thereof due to the increasing restoring forces. This causes the sealing strip to detach itself from the part of the building opposite which it would normally be seals and the gap that should be sealed with the seal opens. Smoke and air can then move through the gap again.
  • the present invention was based on the problem of sealing a gap with a seal of the type mentioned above even if the geometry of the door changes due to heating due to a fire.
  • the expansion element which is arranged in the trigger, between the trigger and the movement mechanism or in the movement mechanism, in the event that the geometry of the door or window changes and a distance between the point at which the trigger is located Normally, and the point at which the trigger is located due to the changed geometry, this distance is compensated.
  • the expansion element is part of the trigger or is arranged between the trigger and the movement mechanism, the trigger is lengthened due to the expansion and the distance is compensated.
  • the compensation can take place within the movement mechanism if the expansion element is provided within the movement mechanism.
  • the expansion element can be arranged in a rod into which the force from the trigger is introduced and which is connected to elements of the movement mechanism via which the force in the movement mechanism is deflected in a different direction.
  • the sealing strip in the event of a fire is made of intumescent material which is arranged between the sealing strip and the housing of the seal
  • the sealing strip of a seal according to the invention is not pressed down by the expansion element alone.
  • the force due to the expansion of the expansion element and acts on the movement mechanism and ultimately on the sealing strip is added.
  • the expansion element only results in length compensation, which is necessary due to the change in the geometry of the door or window. The force for actuation is then further introduced into the trigger and from there transferred to the movement mechanism.
  • the door or window can still be opened so that, for example, people in the fire zone can get to safety or can be brought to safety.
  • This is possible because the force that is introduced into the trigger to move the sealing strip into the sealing position is eliminated when the door or window is opened and the sealing strip then easily moves into the Release position can be transferred in which the door or window can be opened without any problems.
  • the door or window can retain its function even in the event of a fire. At least the function is not hindered by a sealing strip that is pressed against the floor or other counter surface by an intumescent material.
  • the limitation to the fact that the expansion element has only expanded so that it is effective when heated to 90 ° is, on the one hand, to prevent the expansion element from having an effect at temperatures below 90 °. Only at a temperature of over 90° is there a high probability of a fire. And on the other hand, the door can then still be opened without hindrance from the seal if the expansion element achieves an expansion that is greater than would be necessary for length compensation due to the change in geometry. How much the geometry changes often depends on the door or window and the installation situation and cannot be predicted or can only be predicted with great effort. It is therefore difficult to adjust the expansion element precisely to the geometry changes that occur.
  • the expansion element of a seal according to the invention can be a temperature-sensitive material with a positive Have a coefficient of thermal expansion or be made from a temperature-sensitive material with a positive coefficient of thermal expansion.
  • a seal according to the invention can have a container or a housing in which the temperature-sensitive material is arranged.
  • the container can be a capsule that is designed similarly to an expansion element in a thermostat.
  • the temperature-sensitive material can be a fluid, in particular a liquid, a paste or a powder.
  • the temperature-sensitive material can be an intumescent material.
  • the expansion element prefferably be a bimetal element or to have a bimetal.
  • the seal according to the invention can be a seal with a housing as a holder or with another holder that can be attached to the leaf of the door or window.
  • the holders can be attached to the sash, for example, with mounting brackets and screws or directly with screws.
  • all other types of fastening for fastening seals that are already known from the prior art can also be used.
  • any movement mechanism that is already used in known movement mechanisms such as leaf spring mechanisms or scissor mechanisms, can be used as the movement mechanism of a seal according to the invention.
  • the return spring can be an integral part of the movement mechanism, as is usually the case with leaf spring mechanisms.
  • the return spring can also be arranged outside the movement mechanism, as is usually the case with scissor mechanisms.
  • the trigger shown schematically and in section in the figures can be part of a seal according to the invention, which is fastened in or on a wing of a door or window. It has a first trigger part, a second trigger part and an expansion element.
  • the first trigger part has a stop surface with which the trigger can strike a frame of the door or window when the door or window is closed.
  • the second trigger part has a connection structure for connection to a moving mechanism of the seal for which the trigger is intended. For example, it can be connected to a trigger rod or a slider of the movement mechanism.
  • the first trigger part and the second trigger part are slidably mounted on one another. In this way, the distance between the stop surface and the connecting structure can be changed.
  • a recess is provided into which an expansion element is inserted. This expansion element is arranged on one side on the second trigger part and on an opposite side on the first trigger part.
  • the expansion element When heated above 90°C, the expansion element expands. In doing so, it pushes the first trigger part and the second trigger part apart, so that the distance between the stop surface of the first trigger part and the connecting structure of the second trigger part increases. As a result, the trigger has become longer.
  • This extension of the trigger is suitable for counteracting a change in the geometry of the door or window, which could lead to a movement of the sealing strip out of the sealing position.
