Definitions

  • Automatic seals of this type are used in large numbers to seal gaps between a door or gate leaf and a floor, ceiling, lintel or frame.
  • the seal can prevent draughts, noise, smoke or flames from passing from one side of the door to the other.
  • a force is introduced into the trigger when the door or gate is closed.
  • the trigger is pressed against a fixed object, usually the door frame or a stop mounted on a floor or building.
  • the force introduced into the trigger not only moves the sealing strip from the release position to the sealing position.
  • a force is stored in the return spring to move the sealing strip from the sealing position to the release position.
  • the return spring is deflected, which works against the return spring.
  • the force stored by the deflection of the return spring counteracts the force applied to close the door or gate and introduced into the movement mechanism when the trigger is triggered, which is why closing the door or gate is more difficult at the end of the closing movement than during the rest of the closing movement, and it also rests on the trigger when the door or gate is closed. Sliding doors or sliding gates therefore have a tendency to open when the force - usually applied by a person to close the door or gate - is no longer effective.
  • the force stored in the return spring can be so great that, for example, frictional forces or other forces that keep the door or gate leaf closed are smaller than the force exerted by the return spring on the trigger. If this is the case, the door or gate opens a crack until the energy stored in the return spring is dissipated.
  • the invention is based on the object of reducing the effect of the return spring when closing the door or gate and when the door or gate is in the closed state.
  • the seal has a force conversion means which has a fastening tab with which the force conversion means is fastened to the housing, and which has a lever, one end of which is pivotally connected to the fastening tab via a joint with a pivot axis extending transversely to a longitudinal direction of the sealing strip and to the direction of movement of the sealing strip during movement between the sealing position and the release position, and one free end of which projects beyond the stop side of the trigger in a longitudinal direction of the housing.
  • the invention uses the lever law to reduce the force required to operate the seal and thus also to overcome the force of the return spring.
  • the force that has to be introduced into the lever to operate the movement mechanism is smaller than the force that is introduced from the lever into the trigger.
  • the force that acts from the lever onto the stop when the door or gate is closed is also smaller than the force that is introduced into the lever by the return spring via the movement mechanism and the trigger. The force that causes the door or gate to be pushed open is therefore reduced.
  • the force conversion means is designed in such a way that it can be used to retrofit a known seal in order to prepare it for use as a sliding door or gate seal.
  • the fastening tab of the force conversion means can be inserted into a channel of the housing and secured in the channel. Channels suitable for inserting the fastening tab are provided in the housings of many different seals. They are often used to insert fastening brackets into these channels.
  • the fastening tab can be formed by a leg of such a fastening bracket.
  • the mounting tab is glued to the housing, riveted or pressed into the housing.
  • the free end of the lever it is possible for the free end of the lever to be at a greater distance from the hinge axis than a contact point or contact area of the lever on the trigger.
  • the distance of the free end of the lever to the hinge axis can be three to six times greater than the distance of the contact point or contact area to the hinge axis. The greater the distance of the free end to the pivot axis relative to the distance of the contact point or contact area, the lower the force that must be introduced into the lever to actuate the movement mechanism and the lower the force that acts between the free end of the lever and the stop and that could lead to the door or gate being forced open.
  • the fastening tab and the lever can be sheet metal parts.
  • the hinge can be formed by a bolt and rolled-up areas of the sheet metal parts.
  • the lever can have a bead. The bead can prevent the lever from bending when a force is introduced to actuate the movement mechanism of the seal.
  • the seal according to the invention comprises the housing 1, a sealing strip 2, 3, a movement mechanism (not shown), a trigger 4, a return spring (also not shown) and the force conversion means 5.
  • the housing 1 is a uniform profile with a substantially U-shaped cross-section that is open at the bottom with a web 11 and two first legs 12 connected by the web 11. Parallel to each of these first legs 12, a second leg 13 projects downwards at a distance from the first legs. From each of these second legs 13, a a third leg 14 inwards. This third leg 14 and the web 11 form a first channel.
  • Fourth legs 15 also protrude upwards from the web 11. The ends of these fourth legs 15 are angled inwards. The fourth legs 15 and the web form a second channel. In conventional seals, a fastening bracket can be inserted into this second channel, for example.
  • the sealing strip 2, 3 has a retaining strip 2 and a sealing element 3.
  • the sealing element is formed by an elastomer profile. It is attached to the retaining strip 2. For example, it can be drawn into the retaining strip 2 or glued to the retaining strip 2. In the seal shown, the sealing element 3 is drawn into the retaining strip 2.
  • the retaining strip 2 and the sealing element 3 are designed in a known manner.
  • the sealing strip 2, 3 is attached to the movement mechanism which is attached to the housing 1.
  • the movement mechanism can be, for example, a scissors mechanism or a leaf spring mechanism or any other known movement mechanism which is used in automatic seals for moving sealing strips.
  • the trigger 4 is arranged so that it can move in the first channel and is coupled to the movement mechanism.
  • a force for moving the sealing strip 2, 3 from the release position to the sealing position can be introduced into the movement mechanism via the trigger 4.
  • the sealing strip 2, 3 is retracted into the housing 1.
  • the sealing strip 2, 3 is extended from the housing 1.
  • the movement mechanism is further coupled to the return spring or the return spring or several return springs are an integral part of the movement mechanism, for example in a leaf spring mechanism.
  • energy can be stored in the return spring by a force acting on the trigger 4.
  • the return spring releases the energy and it is used as a force to move the sealing strip 2, 3 from the sealing position to the release position by the movement mechanism.
  • the trigger 4 is not directly loaded when a sliding door equipped with the seal according to the invention or a sliding gate equipped with the seal according to the invention is closed. Rather, when the door or gate is closed, the force is first loaded by the force conversion means 5, which passes the load on to the trigger 4.
  • the force conversion means 5 has a fastening tab 51 which is inserted into the second channel and fastened there.
  • a trigger-side end of the fastening tab 51 protrudes beyond the trigger-side end of the housing 1.
  • the fastening tab 51 can also be pushed further into the housing. This trigger-side end of the fastening tab 51 is partially rolled up and forms a first joint part.
  • the force conversion means 5 further comprises a lever 52 which is pivotably mounted on the trigger-side end of the fastening bracket 51.
  • the end of the lever 52 which is pivotally connected to the fastening bracket 51 is also partially rolled up and forms a second joint part.
  • the first joint part of the fastening bracket 51 and the second joint part of the lever 52 are connected to each other via a bolt that is inserted into the rolled-up parts and defines the pivot axis.
  • the pivot axis is arranged transversely to the longitudinal extension of the housing 1 and transversely to the direction of movement of the sealing strip 2, 3.
  • the lever 52 rests with a contact area on a stop surface of the trigger 4. As a result, the lever 52 is extended outwards and protrudes further than the trigger 4 beyond the housing 1.
  • the stop area of the lever 52 is closer to the pivot axis than a free end of the lever 52. If the free end of the lever 52 strikes a fixed stop, possibly a frame or a wall, when the door is closed, the force introduced into the lever 52 is converted into a larger force according to the laws of leverage, which is then introduced into the trigger 4.
  • the lever 52 By means of the lever 52 it is therefore possible to actuate the seal with a lower force than is known from conventional seals. But the lever 52 also works in the other direction.
  • the force exerted by the return spring on the trigger 4 is reduced by the lever 52 according to the laws of leverage and only has a reduced effect on the stop, which minimizes the risk of the return spring pushing the door open.
