Definitions

  • the present invention relates to a sealing device for actuating a lowering seal and a sliding door with such a sealing device.
  • Drop-down seals are used to seal doors and windows. They prevent the passage of light and offer soundproofing and protection against drafts and smoke. In the case of exterior doors, they also serve as splash protection in the rain and, depending on the design, can also protect against flooding.
  • Lowerable door and window seals usually consist essentially of a housing in the form of a downwardly open, hat-shaped or U-shaped profile rail, a sealing strip with a sealing profile that can be raised and lowered in this housing and an actuating mechanism for raising and lowering the sealing strip.
  • the actuating mechanism has leaf springs which are fastened at a first point on the housing, at a second point on the sealing strip and at a third point on a slide. The slide usually merges into an actuating button which protrudes from the housing on one or both sides. When the door is closed, the actuation button on the door frame is pressed in and the sealing strip is automatically lowered against the spring force of the leaf springs and pressed against the floor to form a seal.
  • EP 2 476 857 discloses a drop down seal for sliding doors.
  • the lowering seal is designed as described above and has an actuating button protruding from the seal housing.
  • the door frame In the area of the secondary closing edge, the door frame has a stop element with a downward sloping inclined surface and a rectilinear receiving pocket.
  • a first roller attached to the door leaf runs along this inclined surface and pulls a spring-loaded slide downwards.
  • a second roller arranged on the slide presses a lever onto the actuation button, which thereby activates the actuation mechanism and lowers the sealing strip.
  • the first roll enters the receiving pocket and the lowering movement is stopped. The door leaf is completely closed in this state.
  • the drop-down seal remains in the closed position without the need for any further blocking devices. Only when the door leaf is opened is the roller removed from the receiving pocket, which enables the sealing strip to be raised automatically.
  • This arrangement has the disadvantage that the user has to exert a relatively large amount of force when closing the door, because the slide must be lowered against the spring force and the resistance of the lever pressing on the actuating button.
  • Another disadvantage is that when the door is opened, the automatic lifting of the slide leads to the door opening automatically and the user therefore not maintaining full control during the opening process.
  • Another disadvantage is that the slide is arranged behind the lowering seal in the running direction of the sliding door, so that the sealing strip has to be shortened and cannot seal completely in the area of the secondary closing edge. Furthermore, the end position allows little play, so that precise guidance of the door leaf and precise positioning of all elements are essential.
  • Drop-down seals with an actuation button that can be activated on the front have proven themselves in practice for pivoting door leaves.
  • the power transmission ratio when closing the door leaf is already around 1:30 without any further mechanisms, so that the Actuating button can be pressed in without any noticeable effort when closing the door leaf.
  • the use of such drop-down seals for sliding doors is more problematic, since the power transmission to the actuating button is only 1: 1 and therefore more force has to be used to also push in the actuating button when the door leaf is closed.
  • the inventive sealing device of a sliding door with a displaceably mounted door leaf has a lowering seal with a sealing strip and with a lowering mechanism for automatically lowering and raising the sealing strip.
  • the lowering takes place against a restoring force.
  • the sealing device has an activation unit for activating the lowering seal, the activation unit having a supporting surface directed upwards in the lowering direction and a supporting element which rests on this supporting surface when the door leaf is closed and thereby actuates the lowering seal.
  • the support element When it rests on this bearing surface, the support element preferably actuates the lowering seal by actuating the lowering mechanism.
  • the upwardly directed support surface has the advantage that the weight of the door leaf partially or completely presses on the support element. A person who closes the sliding door has to use relatively little or no additional force to lower the sealing strip. Despite the drop-down seal, the sliding door can be closed with little effort.
  • the support element is preferably connected or operatively connected to the lowering mechanism. It can also be part of the lowering mechanism itself.
  • the support surface and support element are preferably designed in such a way that when the door leaf is closed, an upward force is obtained which is deflected in such a way that it acts on the actuating mechanism.
  • the support surface is preferably a run-on surface and the support element is a run-on element which, resting on the run-on surface, runs along the latter.
  • the ramp surface is preferably a sliding surface and the ramp element is a sliding element.
  • rollers or other suitable means for a relative movement between the support surface and the support element can also be attached.
  • the support surface can also be used to simply raise the support element in order to actuate the lowering seal, in particular the lowering mechanism.
  • the arrangement according to the invention is preferably arranged on the side of the secondary closing edge of the sliding door. However, it can also be arranged on the main closing edge.
  • the activation unit like the lowering mechanism, preferably consists exclusively of mechanical means and preferably does not include any magnets and / or electric motors and / or sensors.
  • the sealing strip can extend over the entire length of the door leaf and can therefore provide an optimal seal.
  • the activation unit is preferably designed such that it holds the sealing strip in a lowered position without the restoring force influencing a sliding movement of the door leaf in the longitudinal direction of the sealing strip. This means that no additional blocking mechanisms are necessary to keep the door leaf in its closed position.
  • the restoring force of the drop-down seal prevents complete closing the sliding door does not. Because of their great weight, many sliding doors have a braking mechanism which brakes the closing movement of the door leaf shortly before the fully closed position is reached. This prevents fingers or other parts of the body from becoming too tight. In preferred embodiments of the invention, this braking mechanism should not be influenced by the restoring force of the lowering seal or by the force required to lower the seal. In addition or as an alternative, it should not have to be expended even more force to close the door. In these embodiments, the lowering seal can therefore be completely lowered even before the fully closed position has been reached and can be held in this position without the need for additional external force. As the closing movement continues, the sealing strip rubs across the floor, but only over a short distance.
  • This "zero force position” can be achieved in various ways. There is preferably a position of the support or sliding element on the support surface or the sliding surface, in which position the sealing strip is completely lowered and in which position the restoring force acting on the sealing strip is deflected in a direction perpendicular to the longitudinal direction of the sealing strip.
  • the bearing surface or the sliding surface preferably runs at least partially in the longitudinal direction of the lowering seal in an inclined direction, preferably running from bottom to top in the closing direction of the door leaf.
  • the slope can be constant or changing.
  • the force that has to be applied to lower the sealing strip can be set by means of the slope. It is thus possible to select power transmission ratios in order to optimize the power to be used.
  • the support surface or the sliding surface preferably has a horizontally extending section on which the support or the sliding element rests in order to hold the sealing strip in the lowered position.
  • the horizontal section preferably adjoins the inclined section.
  • the bearing surface or the sliding surface has a recess in which the bearing or the sliding element rests in order to hold the sealing strip in the lowered position.
  • the recess can be arranged, for example, in the inclined surface or in the horizontal surface.
  • the horizontal surface can also be followed by a counter-inclined surface which is equally inclined or has a different incline than the inclined surface.
  • the support element In the lowered position of the sealing strip, the support element preferably reaches this counter-inclined surface, so that the restoring force acting on the sealing strip makes a contribution to the complete closure of the door leaf.
  • the support surface and the support element preferably move relative to one another.
  • the support surface or the sliding surface is preferably arranged in a stationary manner. This means that the support surface is, for example, fixed in position in the door frame or in the wall or on the floor, i.e. it is stationary.
  • the support element is preferably movable, in particular displaceable, in the longitudinal direction together with the lowering seal. It is preferably fastened together with this in or on the sliding door leaf.
  • the support element is preferably firmly connected to the drop-down seal and the support surface is formed in a module that is separate from the drop-down seal.
  • the upwardly directed contact surface enables a variety of mechanisms to transmit the triggering force to the actuating mechanism of the drop-down seal.
  • the same basic principle can be applied to the most varied types of drop-down seals.
  • the lowering mechanism of the lowering seal has an actuation button which activates the lowering mechanism by the action of an external force.
  • the support element preferably acts directly or indirectly on this actuating button and thereby lowers the sealing strip. Since many known lowering seals have such an actuation button, the use activation unit according to the invention with these known drop-down seals without the latter having to be significantly changed.
  • the lowering seal has a housing in which the sealing strip can be raised and lowered.
  • the operating button can protrude from the front of this housing. In other embodiments, it is aligned with the end face of the housing or it is arranged set back.
  • the recessed arrangement is the most preferred. It is preferably displaceable relative to the housing in the longitudinal direction of the sealing strip.
  • the support element preferably acts on the front side of this actuating button, usually by pressing it in directly or indirectly when the door is closed and by releasing it again when the door is opened.
  • the operating button is pulled to lower the sealing strip.
  • the activation unit according to the invention can also be used with other types of lowering mechanisms, the support element acting directly or indirectly on a suitable point of the lowering seal.
  • the support element is a first arm of a swivel module, a second arm of the swivel module acting on the lowering seal, preferably the actuating button.
  • the support element is a lever arm.
  • the support element can also be part of another force transmission mechanism.
  • the sealing device according to the invention has the advantage that it is relatively insensitive to tolerances, both in the vertical and in the horizontal direction.
  • the assembly of the sealing device is therefore relatively simple and time-saving.
  • the claimed invention also includes a sliding door with slidably mounted Door leaf and a sealing device according to the invention.
  • the activation unit can also be designed as a retrofit kit for existing drop-down seals.
  • the claimed invention therefore also relates to an activation unit of a sealing device according to the invention, the activation unit having a first module which forms the support surface and a second module which has a fastening element for fastening the lowering seal in the door leaf and the support element arranged on the fastening element.
