Definitions

  • connections can in particular be rigid connections that are the result of a joining process.
  • the coupling can in particular be produced via a joint that enables rotation and/or displacement.
  • Such seals are widely used, for example to seal a gap between a floor and a door leaf.
  • these seals usually have an actuating means, which is often referred to as a trigger and which strikes and moves against a frame of the door when a door is closed. The force introduced into the trigger when the door is closed is transferred to the movement mechanism, via which the force is used to move the sealing strip from the release position to the sealing position.
  • the seals usually have a storage device for mechanical energy that is charged when the door is closed. When the door is opened, the energy storage releases the energy, which is then used to move the sealing strip from the sealing position to the release position.
  • the energy storage is usually a spring, which is part of the movement mechanism as a leaf spring, for example, or as a coil spring is executed and is coupled to the movement mechanism. It is also possible for seals to have electrical drives that generate the force to move the seal strip.
  • Such seals are also used in smoke doors and smoke and fire doors and even fire doors to prevent smoke and/or flames from passing from one side of the door to the other side of the door.
  • a smoke protection door must be accessible up to a temperature of 200 to 220°C, i.e. it must be opened and closed without impairment. This is intended to maintain the possibility of evacuation despite the development of smoke. At temperatures of more than 220°C, accessibility no longer needs to be guaranteed. The door can then block such a door opening that it can no longer be opened easily, especially without the help of tools.
  • plastic parts of the seal including the sealing profile
  • intumescent material is often provided on the sealing strip, which presses the retaining profile of the sealing strip against the floor when the plastic parts burn in order to obtain a flame seal.
  • the invention is based on the object of modifying an automatic seal in such a way that smoke protection is ensured even if these ends move outwards if the lower ends of the door frame are not backed.
  • the seal comprises two parts which are connected or coupled to one another in such a way that the connection or coupling is released automatically under the influence of heat.
  • connection or coupling results in the sealing strip falling down due to the action of gravity and resting on the floor and closing the gap between the door leaf and the floor without the sealing strip being moved downwards by the movement mechanism. It is then irrelevant whether the movement mechanism is activated or not and whether the trigger is activated or not.
  • the sealing strip seals the gap as soon as the connection or coupling is released.
  • connection that can be detached independently under the influence of heat can be an adhesive that loses its stability when exposed to heat. This can be achieved in particular if the adhesive used for bonding loses its resistance when exposed to heat.
  • the adhesive can be, for example, a hot melt adhesive. But it can also be an adhesive, for example a polymer adhesive, one-component or multi-component adhesive, epoxy resin adhesive.
  • connection or coupling that can be released independently under the action of heat can also be a connection or coupling produced by positive locking, to which the joining partners connected to one another by the connection that can be released automatically under the action of heat or the coupling partners connected to one another by the coupling that can be released independently under the action of heat are composed, for example by Laying on, putting on, inserting, inserting, telescoping, hooking, setting, springily spreading, etc.
  • a connection or coupling that can be released independently under the influence of heat can be produced in that the thermal expansion coefficients of the joining partners or coupling partners are different from one another or even have opposite effects and As a result, the two joining partners or coupling partners lose their positive connection or coupling to one another under the influence of heat.
  • connection or coupling which can be released independently under the influence of heat
  • a joining partner of the connection or coupling partner of the coupling being in contact with an element which changes its shape under the influence of heat in such a way that the change creates a force on the Joining partner or coupling partner is exercised, which destroys the connection between the two joining partners or coupling partners or promotes destruction of the connection between the two joining partners or the coupling between the two coupling partners.
  • This element may be an intumescent element or one which essentially does not or only slightly changes its volume but changes its shape, such as a bimetal.
  • connection or coupling which can be released independently under the influence of heat, can be brought about or improved by at least one of the two joining partners or coupling partners changing its shape under the influence of heat in such a way that the change exerts a force on the other joining partner or coupling partner Connection between the two joining partners or the coupling between the coupling partners is destroyed or promotes such destruction.
  • Changing joining partner or coupling partner can be a joining partner or coupling partner made from an intumescent material or one that essentially retains its volume but changes its shape, such as a bimetal.
  • connection or coupling which can be released independently under the influence of heat, can also be brought about or improved by at least one of the joining or coupling partners or an adhesive used changing its physical state, for example becoming liquid or turning into a gas.
  • the door may no longer be accessible because the sealing strip lying on the floor prevents the door from being opened.
  • the automatic seal becomes a sliding seal, in which the sealing element of the seal constantly drags on the floor. The door can then still be accessed.
  • the weight is smaller than the force that is applied by the intumescent material in the known seals. Therefore, a door with a seal according to the invention can be opened more easily when the connection or coupling is released, in contrast to a door with one of the known seals.
  • connection or coupling dissolves automatically at a temperature of 200 to 220°C. If the adhesive dissolves at this temperature, smoke-tightness would be achieved at this temperature despite the lower ends of the door frame moving outwards. This then corresponds to the regulations for smoke-tight doors.
  • the movement mechanism can be any movement mechanism used to move weatherstripping in automatic door seals.
  • it can be a movement mechanism with leaf springs or a scissor mechanism.
  • the drive for introducing the force into the movement mechanism for moving the sealing strip from its sealing position to its release position can be a return spring.
  • a seal according to the invention has a housing 1 as the first part of a fastening means, which has a constant cross-sectional profile over its length.
  • the housing essentially has the shape of an inverted U with two legs 12 and a connecting web 11 which connects the two legs 12 to one another.
  • two webs 111 are attached on an inside of the web 11 of the housing 1.
  • the housing can be secured in a groove of a door leaf in a known manner. Fastening can be done, for example, with the help of fastening brackets, which will be discussed later.
  • the person skilled in the art is familiar with various types of attachment from the prior art, in particular from published patent applications.
  • the housing can be modified, for example to provide channels, webs, screw holes or something else in the housing that is useful for attaching the seal to a door.
  • a seal also has a sealing strip 13, 14.
  • the sealing strip is designed in two parts. However, it could be one-piece or have more than two parts. Basically, any sealing strip known from the prior art can be used.
  • the sealing strip comprises a rigid holding means 13, preferably made of aluminum, and an elastomeric sealing profile 14. In the example, both have a constant cross-sectional profile over their length.
  • the holding means 13, like the sealing profile is essentially U-shaped in cross section.
  • the holding means 13 as well as the sealing profile 14 each have a connecting web 131, 141 and two legs 132, 142, which are connected to one another via the connecting web 131, 142.
  • the sealing profile 14 is fastened in locking channels 133 of the holding profile 13 via locking webs 143.
  • two webs 134 are provided, which together with the connecting web 131 form channels.
  • the sealing strip and the housing are indirectly connected to one another via two movement mechanisms Sa, Sb.
  • the movement mechanisms in the example are scissor mechanisms Sa, Sb, such as those from the document EP 3 284 898 A1 are known.
  • the movement mechanisms Sa, Sb are coupled to two drives, namely a first drive 16 for driving the movement mechanisms Sa, Sb for moving the sealing strip from a release position in which the sealant is removed from the counter surface into a sealing position in which the sealant is on a The counter surface rests in a sealing manner, and a second drive for driving the movement mechanisms Sa, Sb for moving the sealing strip from the sealing position into the release position.
  • the first drive is a trigger 16, which hits a door frame when the door is closed and is pressed in
  • the second drive is a return mechanism which includes a return spring R.
  • the reset mechanism is also from the document EP 3 284 898 A1 known.
  • the seal When the seal is triggered by pressing in the trigger 16, the movement of the trigger 16 is converted into a movement of the sealing strip relative to the housing 1 from a release position into a sealing position.
  • the seal In order to protect the movement mechanisms Sa in a so-called overload case, the seal also has two overload mechanisms Ua, Ub on. These are also from the document EP 3 284 898 A1 known.
  • the fastening means also includes so-called module housings 2a, b. These have a substantially constant cross-sectional profile in the shape of an inverted U. They have a connecting web 21 which connects two legs 22 of the module housing 2a. Webs 221 are attached to the inside of the legs 22. Together with the connecting bridge, these form 21 channels.
  • each module housing 2a, 2b An outside of the connecting web 21 of each module housing 2a, 2b is glued between the webs 111 to an inside of the web 11. As a result, these two parts of the fastening means 1, 2a, b are firmly connected to one another.
  • the adhesive is selected so that it loses its resistance at a temperature of 200 to 220°C.
  • the connection between the two parts of the fastening means 1, 2a b and the module housing 2a, 2b and the movement mechanism Sa, Sb and others coupled to it are loosened and are mounted on a lower end of a door leaf Seal falls down so that the sealing strip 13, 14 and in particular the sealant 14 rests on the floor, thereby preventing smoke or flames from passing through from one side of the door to the other side of the door.
