Definitions

  • the present invention relates to a sliding door with a door leaf, which can be transferred between an open position and a closed position, wherein the door leaf releases a passage opening in the open position, which has a substantially flat, barrier-free floor structure.
  • Such sliding gates are in the art in different applications in use to be able to selectively close one of steps, protrusions, or other obstacles passage opening.
  • gates are in use in the prior art, which are exposed to changing wind influences. Such gates are usually designed to withstand wind forces within a certain range without significant distortion of the door leaf. In a storm, however, wind gusts with extremely high wind speeds act on the door leaf, so that the load limit of the door leaf is exceeded by a multiple. This may disadvantageously entail damage to the door, which requires a costly repair or even replacement of the door leaf.
  • a swing gate with a locking device which has on one side a stop element, which is pivotally mounted and does not protrude in an inactive position on the bottom surface. In an extended position, however, the stop element is so on the pivotally mounted door, that opening the door is not possible.
  • the object of the present invention is to provide a sliding gate of the type described above, in which a deformation of the door leaf over a predetermined amount addition when required, especially in a fire or a storm, reliably prevented.
  • the holding element can be moved into the active position protruding from the floor structure, in which the deformation of the closed door leaf is limited.
  • the transfer of the retaining element in the active position is made in an embodiment as a fire door in particular when a fire is detected.
  • high and locally varying temperatures cause high voltages in the door leaf.
  • the changes in shape of the door leaf occurring in the event of fire are, according to the invention, perpendicular or transversal, that is to say by the holding element. in both directions, limited to the longitudinal extension plane of the door leaf, which in particular has the advantage that in case of fire a reliable room closure is guaranteed.
  • the deformation of the door leaf is limited by the retaining element to a predetermined extent, a passage of flames or hot gases is avoided in the case of fire on the side facing away from the fire side of the door leaf.
  • the change in shape of the door leaf can be limited to the holding element even at gates that are exposed to changing weather conditions. In the event of a storm, the holding element is moved into its upright position from the soil structure, in which the possible deformation of the closed door leaf is reduced to a minimum.
  • the invention should not be limited to the execution of the door as a fire or storm protected gate. A variety of other uses of the gate are conceivable for those skilled in the art, in which the limitation of the deformation of the door leaf in case of need, especially when exceptional conditions prevail, is advantageous.
  • the drive device is connected to a fire sensor, so that the drive device in Fire is activated.
  • a fire sensor for example, a smoke detector can be used.

  • the drive device is connected to a wind sensor, so that the drive device is activated in the event of a storm.
  • the wind or storm sensor is in particular configured to detect the instantaneous wind speed. When a predetermined maximum wind speed is exceeded, the holding element is moved by the drive device in its active position.
  • Wind sensors may be provided as wind sensors, which are known in the prior art in another context with awnings or the like.
  • a reliable, rapid transfer of the retaining element in the active position, if necessary, is ensured if at least one spring element and an electromagnet are provided as a drive device, wherein in the normal position of the electromagnet holding down the holding element against the force of the spring. As long as the power supply of the electromagnet is upright, the electromagnet indirectly or directly exerts a magnetic force on the holding element, which reliably holds the holding element in the lowered in the soil structure normal position.
  • the power supply to the electromagnet interrupted, whereupon the holding element is moved under the action of the spring in the projecting beyond the soil structure active position in which the Deformation of the door leaf is limited by the retaining element.
  • the holding element is mounted on a slidably mounted carriage.
  • the carriage rests in the active position on a preferably plate-shaped stop element, wherein the stop element is preferably arranged flush with the rest of the soil structure.
  • the carriage is pressed in the active position of the holding member by the force of the spring against the stop member, whereby a particularly stable arrangement can be achieved.
  • the stop element has at least one opening through which the holding element protrudes in the active position.
  • the opening is preferably formed substantially complementary to the holding element.
  • the stop element is arranged on pin-shaped fastening elements, which are accommodated in a substantially trough-shaped housing for receiving the retaining element in the normal position.
  • pin-shaped fastening elements are attached to the particular plate-shaped stop element, with which the plate-shaped stop element is supported uniformly.
  • the displaceable, spring-loaded mounting of the carriage can be accomplished in a structurally simple manner, if preferably each pin-shaped fastening element is received in a force acting between the trough-shaped housing and the carriage coil spring.
  • the carriage preferably has a corresponding for each pin-shaped fastener Recess, through which protrude through the pin-shaped fasteners.
  • a U-shaped rail is provided as a holding element, the legs of which engage around the door leaf in the active position.
  • a lower end portion of the door leaf in the active position of the holding element within the U-shaped rail can be arranged.

  • the defined between the legs of the rail guide tapers from the top of the rail toward a base connecting the legs of the rail to the arrangement of the door leaf in to facilitate the rail.
  • the door leaf is guided sideways or in a direction parallel to the soil structure, it being also advantageous in this case when the legs of the U-shaped rail viewed in the closing direction of the door leaf on each other run.
  • the door leaf has a groove-shaped recess at an end face facing the bottom structure in the closed position.
  • a holding element as a pin-shaped Engagement part, preferably with a guide roller, is provided.
  • a retaining element is provided widening at least in sections in the closing direction of the door leaf engaging part; In this case, the door leaf first encounters the converging tip of the engagement member during the closing operation and is then guided along the wedge-shaped widening engagement member until the door leaf reaches its closed position.
  • At least two holding elements are arranged distributed in the longitudinal direction of the passage opening, wherein the holding elements are preferably arranged at a distance from an edge portion of the passage opening, and in particular arranged such that the holding elements the passage opening in the longitudinal direction divided into substantially equal sections. Consequently, by means of a plurality of preferably uniformly distributed over the length of the door leaf in the closed state arranged holding elements, the forces acting on the door leaf forces can be efficiently absorbed to avoid deformation of the door leaf as far as possible.
  • the sliding gate it is favorable in terms of an additional limitation of the deformation of the door leaf in its closed position, when the door leaf in the closing direction is displaceable up to a laterally delimiting the passage wall, wherein in a wall portion facing the door leaf, a further holding element is accommodated between a fully recessed in the wall portion normal position and a projecting beyond a plane defined by the wall portion level active position by means of a drive device is displaceable.
  • a further holding element is particularly advantageous in sliding gates in which the door leaf in the closed position is not accommodated in a rigidly arranged holding rail (a so-called inlet profile) or the like.
  • the Further retaining element or the associated drive device can be designed in accordance with the retaining element integrated in the base structure-which is absolutely necessary in order to avoid adverse changes in shape of the door leaf-so that reference is made to the above explanations in order to avoid repetition.
