Definitions

  • the invention relates to a door with a closed from a wall opening a closed position in an open position in which it is arranged substantially overhead, along a predetermined path liftable door leaf, the door leaf two, three or more in the closed position arranged one above the other and respect, at least when reaching the open position by a pivoting movement of a lower door leaf element having this edge in a lifting direction with respect to a in the closed position above arranged in the closed position above hinge axis perpendicular to the predetermined path extending hinge axes hinged door leaf elements, and in the closed position Torblattelement respect.
  • the predetermined path is separately raised.
  • Gates of this type are used for example in the form of garage doors, factory gates or hall doors.
  • the door leaf is usually formed in several parts in the manner described above, wherein it is aligned in the closed position approximately in a vertical plane and circulated by a frame frame.
  • the door leaf is usually moved along a predetermined by a guide rail track in an overhead position in which it extends approximately parallel to the ground and approximately perpendicular to the closable with the door leaf wall opening approximately in a horizontal plane.
  • This opening movement is usually arranged as well as the closing movement of the open position to the closed position with both sides of the door leaf and fixed to the wall guide rails of the guide rail assembly and guided on the door leaf and guided by the guide rails guide elements, such as guide rollers.
  • the guide rails usually each have a substantially vertically extending straight vertical guide rail segment, in each case a usually substantially horizontally extending horizontal guide rail segment and in each case one the vertical and the horizontal guide rail segment interconnecting arcuate guide rail segment.
  • Such doors also referred to as sectional doors, have the advantage that, when actuated, the door leaf does not have to be pivoted into the space lying in front of the building to be closed with the door, so that a particularly space-saving operation of the door leaf is possible.
  • the door behind the room behind it should be completely and safely closed. In the open position, the gate should release the clear wall opening as far as possible.
  • a low lintel height i. the smallest possible distance between the upper edge of the wall opening and the ceiling of the space to be closed, desired.
  • a wall opening form the height of which corresponds almost to the ceiling.
  • the individual door leaf elements in the closed position are preferably arranged approximately in a plane.
  • the door leaf element following the closing movement which is also referred to as the upper door leaf element, and the door leaf elements arranged underneath are to lie in one plane. So that the clear wall opening in the open position as far as possible leh is released, the projecting in the opening movement Torblattelement, which is also referred to as the lower Torblattelement, in the open position as little as possible protrude into the clear wall opening.
  • the arcuate guide rail segment completely in the camber area of the wall opening, and the horizontal and vertical guide rail segments each have at least the length of the entire door leaf height. Then, in the closed positions of the door leaf, the individual door leaf elements can be arranged one above the other in one plane and completely close the clear wall opening. In the open position, all Torblattemia can be arranged in the horizontal guide rail segment, whereby the clear wall opening is completely released. In practice, the required installation heights and installation depths for such a guide rail arrangement are not given, especially in garages. Next difficult in the open position completely arranged in the horizontal door leaf, the initiation of the closing process considerably.
  • a breakaway moment On a gate leaf resting in the horizontal, a breakaway moment must act when the closing movement is initiated. This serves to initiate a movement of the lower edge of the door leaf in the vertical until the located in the vertical portion of the door leaf has reached a certain minimum momentum, so that the closing movement of the door leaf can be done independently by gravity, without further external forces in effect. If the door leaf completely arranged in the horizontal, the required breakaway torque is maximum, and it regularly requires an additional device that initiates the closing movement by a Kraftweinturm on the door leaf.
  • a pushing device is disclosed in DE 101 01 560 A1 and in US Pat. No. 2,651,360, which triggers and supports the closing movement of the door leaf by a force acting on the upper edge of the upper door leaf element.
  • US Pat. No. 2,651,360 discloses a pushing device with a spring element which is fixedly coupled to the upper edge of the upper door leaf element.
  • this pushing device is coupled simultaneously with the traction means connected to the lower edge of the lower door leaf element, which raises the door leaf from the closed position to the open position.
  • This design requires complicated assembly and extension of the horizontal guide rail segment to accommodate the pusher therein.
  • DE 101 01 560 A1 which is not fixedly connected to the upper door leaf element but which which can only be applied to this.
  • the construction of DE 101 01 560 A1 compared to the construction of US 2,651,360, enables easier assembly and requires a shorter horizontal guide rail segment. In both cases, however, an additional assembly step in the installation of the gate is required.
  • Another problem is in the case where the arcuate guide rail segment is at least partially disposed in the clear opening.
  • This problem occurs, for example, when the lintel height is small compared to the radius of the arcuate guide rail segment. This may be due to the fact that a large clearance height is required for the space to be closed compared to its total height and thus the lintel height is small.
  • increasing the radius of the arcuate guide rail segment, thereby allowing a higher speed of the door leaf to move from the open to closed positions without disturbing noise may result in the arcuate guide rail segment being at least partially disposed in the clear opening. Then, among other things, the problem is to achieve a complete closure of the clear wall opening in the closed position.
  • WO 97/42387 and EP 0 897 448 B1 disclose a door leaf with a pivoting lever arranged on the upper edge of the upper door leaf element.
  • the guide rollers arranged on the upper edge of the upper door leaf element are arranged in the arcuate guide rail segment.
  • the upper door leaf element is therefore not arranged in the same plane as the Torblattemia arranged underneath, but is tilted relative to this plane.
  • the pivot lever now allows a tilting of the upper door leaf element relative to the guide rollers on the vertical plane, so that in the closed position, all Torblattetti can be arranged in a plane.
  • Such a pivot lever is also disclosed in DE 10 2005 043 229 A1 and in DE 10 2005 008 027 U1 and serves as an adjusting lever for adjusting between a closed position and a pivot position in which the upper door leaf element is pivoted inwardly on the arcuate guide rail segment ,
  • US 5,846,127 discloses a sectional door with such a pivot lever.
  • DE 101 01 560 A1 guide rail assembly Another way to achieve a complete closure of the wall opening at a low lintel height is given by the disclosed in DE 101 01 560 A1 guide rail assembly.
  • this guide rail assembly is a second horizontal Guide rail segment arranged in the direction of gravity above the horizontal guide rail segment.
  • This second horizontal guide rail segment carries only the upper door leaf element and is located in the lintel area.
  • the guide element arranged at the upper edge of the upper door leaf element is arranged in the closed position of the door leaf in the second horizontal guide rail segment, so that the lower edge of the upper door leaf element with the door leaf element underneath is arranged in a plane.
  • this also referred to as low-fall hardware guide rail assembly requires two horizontal guide rail segments and is therefore expensive to install and generates additional costs.
  • the lower door leaf element protrudes in the open position into the clear wall opening.
  • the arcuate guide rail segment is at least partially disposed in the clear wall opening and the length of the horizontal guide rail segment is shorter than the height of the door leaf.
  • this arrangement may also be due to the fact that the traction means arrangement designed to lift the sectional door from the closed position into the open position can not completely lift the lower door leaf element into the horizontal plane.
  • Such Switzerlandstoffitz extract generally consists of a traction means, for example in the form of a pull rope or a pull chain, which is connected at its one end to the lower edge of the lower Torblattelements, and the other end is coupled via guide and / or pulleys to a pulling mechanism ,
  • the guide and / or deflection rollers are generally arranged at a distance from the camber, which is less than the radius of the arcuate guide rail segment.
  • the lower edge has reached its end position in the opening movement, because with the aid of the traction means and thus exerted on the lower edge tensile force no further movement of the lower edge of the Torblattiatas in the opening direction can be more effected.
  • the lower edge of the lower Torblattelements is arranged in this arrangement in its end position in the arcuate guide rail segment and blocks a portion of the clear wall opening. An intrusion of the door leaf in the clear wall opening but may also be intended to reduce the required breakaway torque when initiating the opening movement, but also in this case, an undesirable reduction of the clear wall opening is to be accepted.
  • the FR 2 694 331 A1 discloses a second vertical guide rail segment, which leads into the lintel area in order to guide the guide element fastened to the lower edge of the lower guide rail segment into the lintel area.
  • the clear wall opening is optimally released.
  • this design requires a larger breakaway torque to initiate the closing movement.
  • the lower edge of the lower door leaf element Due to the interaction of the traction means and the guide element connected in an articulated manner to the lower door leaf element, the lower edge of the lower door leaf element can be raised particularly far upwards. However, since the lower edge of the lower door leaf element tilts down in this construction, the clear wall opening is not optimally released.
  • This lever arrangement makes it possible to raise the lower edge of the lower door leaf element with respect to the guide roller articulated there via the lever arrangement so as to completely release the clear wall opening.
  • a pulling means providing the opening movement is located directly at the lower edge of the lower door leaf. coupled to the lever assembly, wherein the traction means is achieved in gates according to WO 2004/099542 A1 and EP 1630336 A1, wherein is achieved by the position of the articulation point of the lever arrangement on the lower door leaf element optionally in conjunction with additional guide rollers, that the lower edge of the Torblattettis is pivoted separately in a lifting direction when the coupled to the lever assembly guide roller reaches the arcuate guide rail section.
  • the clear wall opening can be released further in the open position than in conventional sectional doors.
  • the lower edge of the door leaf then protrudes less far into the clear wall opening than is the case with conventional sectional doors.
  • the free passage height of the wall opening in the open position of the door leaf is thereby increased.
  • the invention is based on the object to provide gates, with which both the clear passage height of the wall opening can be well utilized, as well as a trouble-free long-term operation is ensured.
  • this object is achieved by a development of the known goals, which is essentially characterized by the pivotal movement of the lower Torblattimplantations in the lifting direction at least along a portion of the predetermined path limiting limiting device.
  • This invention is based on the recognition that an additional degree of freedom of movement is introduced by the desired in reaching the open position pivotal movement of the lower edge of the door leaf in the lifting direction, which can interfere with other phases of the Torblattieri and wear-promoting.
  • the pivoting movement of the lower door leaf element in the lifting direction would cause the lower door leaf element to pivot out relative to the door leaf element arranged above it in the space lying in front of the door leaf.
  • This swiveling can lead to a sliding contact of the lower edge of the lower door leaf element at the usually arranged in the region of the lateral edges side seals in the course of the opening movement, resulting in a increased wear of the side seals leads.
  • the additional degree of freedom can further lead to an uncontrolled pivoting movements of the lower edge of the lower door leaf element increasing the wear of the articulated connections between the door leaf element. This can be prevented according to the invention by using the limiting device. As a result, the wear of gates according to the invention is also reduced when these gates are equipped to allow better use of the clear wall opening.
  • the limiting device according to the invention can be designed so that it is effective not only in the region of the vertical guide rail portion and the first part of the arcuate guide rail portion, but also where a raising of the lower edge of the lower Torblattiatas is desired, ie in the region of the horizontal Guide rail portion adjacent end portion of the arcuate guide rail portion. In this area, it can be prevented by the inventively provided limiting device, that the lower edge of the lower door leaf element strikes against the deflection roller or the deflecting pinion for the traction means. This also improves the operational reliability of gates according to the invention.
  • the door leaf element leading in the opening movement / following in the closing movement is referred to as the "upper door leaf element.”
  • the door leaf element following the opening movement / leading in the closing movement is referred to as the “lower door leaf element”. If further door leaf elements are arranged between the upper and the lower door leaf element, these are referred to as "intermediate elements”.
  • the lower edge of the lower door leaf element does not follow the predetermined path upon reaching the open position, which describes at least one of the intermediate elements in the transition from the closed position to the open position, but the lower edge of the lower door leaf element is when reaching the open position in comparison to the door leaf elements arranged above can be lifted separately.
  • the lower door leaf element can thus be moved in the direction of the plane in which at least the intermediate elements are arranged. This level is overhead. This plane can be approximately parallel to the horizontal plane.
  • the lower door leaf element can be arranged completely in the open position in the plane of the intermediate elements, and thus can lie completely in the lintel area. Thus, the clear wall opening is completely released.
  • the lower edge of the lower door leaf element can also block a region of the clear wall opening.
  • Next can be generated by the separately liftable edge necessary for the initiation of the closing movement breakaway torque.
  • the separately elevatable edge of the lower door leaf element is further raised in comparison to the lower edge of a conventional sectional door. This additional potential energy is converted into additional kinetic energy during the transition to the closed position, whereby the initiation of the closing movement can be facilitated and / or made possible.

Abstract

L'invention concerne une porte comportant un tablier pouvant être soulevé sur un trajet prédéfini d'une position de fermeture fermant une ouverture murale à une position d'ouverture dans laquelle il est agencé sensiblement tête en bas, le tablier présentant deux, trois ou plus de trois éléments de tablier disposés les uns au-dessus des autres dans la position de fermeture. Ladite porte est perfectionnée selon l'invention du fait qu'un bord inférieur du tablier, dans la position de fermeture, et suivant le mouvement lors du soulèvement du tablier, peut être soulevé séparément par un mouvement de pivotement d'un élément de tablier inférieur présentant ce bord, par rapport à un élément de tablier situé au-dessus dans la position de fermeture, et par rapport au trajet prédéfini.
