Definitions

  • the invention relates to a door with a door leaf that can be moved by means of lateral guides, the door leaf being equipped on its bottom, lateral, outer areas with support devices for attaching support ropes, through which the change of location and any open position of the door leaf is ensured.
  • a gate arrangement with a cable drive has become known.
  • a cable deflection is arranged, by means of which it is possible to provide the drive cable at the same level as the floor of the door leaf and at the same time a fastening device at a distance from the door leaf threshold.
  • the guidance in the area of the rope deflection is achieved by the shape of a semicircle.
  • EP 2 514 896 B1 describes a safety device for a moveable door leaf of a door, in particular a sectional door.
  • the door leaf is moved between an open position and a closed position via guide rails, this change in location being achieved by pulling cables articulated to the side of the door leaf.
  • These pull ropes are fastened in the lower area of the door leaf and each guided over deflections.
  • a safety device is used to protect against a loss of tension in the tension ropes.
  • safety devices are used to secure the door leaf in the event of a defect in one of the two suspension cables.
  • safety devices are for example in the DE 28 33 483 C2 and the DE 84 19 7 46 U1 has been revealed.
  • Safety devices of this type are used for doors that can be opened upwards, in order to prevent the door leaves from falling if the supporting means used fail.
  • suspension means in the form of suspension ropes must be equipped with multiple security compared to the door leaf weights used. If one of the suspension cables breaks, the door leaf will inevitably tilt within the lateral guides and these breaks will also be detected by suspension cables using safety devices.
  • the object of the invention is to construct a door with a movable door leaf, which can be made cheaper in its manufacturing costs without restricting the safety concept during operation.
  • Such a construction should not only lengthen the lay-on time of the suspension elements used in the form of suspension ropes, but also dispense with automatically acting safety devices, which would otherwise normally respond in the event of a break in at least one of the two suspension ropes, thereby and to reduce the operating costs of the gate.
  • the use of suspension elements should not be resorted to, the safety factor of which is greater than 6 against break resistance, because their diameter is significantly thicker, and the costs of such suspension elements are also significantly greater in terms of amount.
  • Suspension ropes cannot be dimensioned for gates in such a way that they can be used indefinitely and therefore permanently. This is particularly due to the fact that they are subject to wear. Such wear can be caused by changing the rope diameter, for example also by corrosion. For this reason, suspension ropes are subjected to regular testing when used on gates. Such a test can be used to determine whether an installed suspension rope is ready for discard. The point in time when the lay-in time is no longer justifiable with the existing security requirements is considered to be discarded. For example, wire breaks or corrosion or the like can result in discarding status. The reduction in the diameter of the suspension rope compared to the original diameter during assembly is also a sure sign of the fact that it has been discarded. These changes in the diameter of the suspension rope will also result in the dwell times being significantly reduced due to the dynamic loading of the suspension rope at bending points and incorrect radii.
  • the operating time of suspension ropes is determined by various factors.
  • An essential factor here is the constant bending of the rope at the deflection points of the suspension ropes. With such bends, the suspension cable is stretched, for example, on the upper side of its cross-section and at the same time compressed on the lower side.
  • These are dynamic loads which, in particular, have an enormous impact on the laying time of the suspension rope, because these different load cycles can lead to tears in individual strands or cores of the rope over the course of the laying time.
  • the breaking strength of a The suspension rope is determined by the rope strength, fatigue and the rope diameter.
  • the use of suspension cables on movable door leaves with the area of the safety suspension cable guide in the form of an optimized link guide is divided into essentially two sections, namely a dynamic section and a static section.
  • the support cable In the static section, the support cable is in constant contact with the existing link guide, whereas the support cable in the dynamic section comes into contact with the link guide for lifting and resting in alternation.
  • This alternating contact with the link guide must be carried out as gently as possible, because this increases the lay-up time of the suspension cable many times over, which also helps to ensure that suspension cable breaks can be safely avoided until their prescribed service life is reached and operating costs can be saved.
  • a safety suspension cable guide with a geometric course of a link guide in which the link guide is formed from several radii, these radii being designed to be substantially different in their absolute amounts. These different radii lead to a harmonious setting guide training.
  • the center points of the individual radii of the link guide are essentially on the same plane. The transitions between two adjacent radii are connected to one another by a tangential course.
  • the support cable can enter such a link guide, which can be equipped as a groove with a recess. Through the entry, for example, the support cable is inserted into the link guide at an obtuse angle. This avoids high loads on the suspension rope in the entrance area.
  • a safety suspension cable guide can consist of several radii in its link configuration, which in particular can also be adapted to the diameter of the suspension cable used.
  • a first radius can thus be formed, which then merges seamlessly into a second radius.
  • the absolute value of the second radius is significantly larger than the first radius.
  • the larger second radius can also be followed by a third radius, which is then present, for example, at the end of the link guide.
  • the absolute value of this third radius is then again significantly smaller than the second radius.
  • the support cable is steered via the third radius in the direction that it needs to attach to a supporting device used. In such a case, too, a buckling load on the suspension cable is avoided via the third radius as the end radius.
  • the link guide from only two radii. These two radii are also seamlessly and harmoniously joined to one another without edges and are designed to be significantly different in their absolute amounts. This construction of the link guide creates a tangential course of the link guide with a dynamic section related to the suspension cable and a static section.
  • link guide is arranged in a recess.
  • Such a lateral link guide for the suspension cable in conjunction with the safety suspension cable guide, provides excellent lateral support for the suspension cable, especially in the area of the dynamic section.
  • a support device can be used for guiding and attaching the support cable, which includes both the link guide and an additional safeguard of the support cable against breakage, in the form of a switch element.
  • a support device for mounting on the door leaf of the door can thus be used to attach support ropes to door leaves of any design.
  • safety suspension cable guides can be used in connection with support devices with a link formation in a dynamic and a static section in all door leaves with different designs. Particularly in the case of sectional doors, the door leaves of which consist of individual sections that are hinged to one another. But the support devices can also be used in the same way for one-piece door leaves.
  • This attachment of the support device 1, 2 on the right side edge 25 of the door leaf 11 is in the Figure 2 shown again separately.
  • the support device 1, 2 can be connected to the door leaf 11 via fastening bores 24 using screws (not shown).
  • An angled stop side 13 of the support device 1, 2 rests against the side edge 25 of the door leaf 11.
  • the support cable 12 is guided via a link guide 3 contained within the stop side 13.
  • an end connection 29 which can consist, for example, of a compression sleeve connection.
  • a connection element 30 is provided to the support device 1, 2.
  • the connecting element 30 penetrates a protruding assembly area 26 of the support device 1, 2 via a bore 18.
  • a support 16 On the upper side of the support device 1, 2 with the assembly area 26 is a support 16 next to a support 17 available, on which a safety switch (not shown) can be placed by means of a threaded hole 19. In the event of a break in the support cable 12, the motor drive of the door leaf 11, which is also not shown, would be shut down via the safety switch (not shown).
  • the support device 1, 2 essentially consists of a base plate 14 which has the bearing 15 on its front side 28 in the lower region. In the upper area, the protruding assembly area 26 is visible, which is secured against kinking by essentially triangular reinforcements 23. A rear region 27 of the support device 1, 2 is essentially straight in order to enable it to be fastened to the door leaf 11 via the fastening bore 24.
  • the stop side 13 is provided. In the area of the stop side 13 there is also the link guide 3. Within a groove 9, which in particular the Figures 6 and 7 can be seen, the link guide 3 is shown.
  • the support cable 12 has only a slight lateral play in the groove 9 due to its adapted diameter. This tour alone results in an extension of the lay-up time.
  • the course of the link guide 3 with a dynamic section X and a static section Y in the support device 1, which is also provided with the above-described groove 9, is shown in a sectional view. Only the lower part of the support device 1 is shown.
  • the entry of the support cable 12 in the area of the link guide 3 is shown at an angle ⁇ .
  • the angle ⁇ has been specified in relation to a reference line 8.
  • the support cable 12 can enter the groove 9 with a slightly inclined course when it enters the link guide 3 without additional loading.
  • the carrying cable 12 emerges when leaving the carrying device 1, for example at an angle ⁇ .
  • the angle ⁇ is also related to the reference line 8.
  • the two angles ⁇ and ⁇ can have different amounts as required, the angle ⁇ being in the range of essentially 10 ° and more and the angle ⁇ in the range of 1 ° and more.
  • the angle sizes of these two angles depend on the one hand on the construction of the support device 1 but also on the diameter of the support cable 12.
  • the absolute value of the second radius 4 is significantly larger than the first radius 5.
  • the first radius 5 can essentially be in a range from 8mm to 12mm and the second radius 4 in a range from 35mm to 50mm lie.
  • These details of the radii in their absolute amounts relate to a diameter of the support cable that is essentially in a range from 4mm to 7mm, in a special case with very heavy door leaves 11 also 8mm and more lies.
  • FIG. 9 Another preferred embodiment of a support device 2 is shown with a sectional view in the area of the link guide 3.
  • the support cable 12 enters the area of the link guide 3 over a first radius 5.
  • the first radius 5 has also been shown without a transition into a second radius 4, then it merges into a third radius 6 without a transition, ie preferably tangentially.
  • an end radius 7 can also be formed here.
  • the absolute value of the first radius 5 is significantly smaller than the second radius 4 and can, for example, be in a range from 8mm to 12mm for suspension cables 12 with a diameter of 6mm to 7mm.
  • the second radius 4, which adjoins the first radius 5 without a transition, can also be in a range from 35mm to 50mm here.
  • the third radius 6 adjoining the second radius 4 has a different absolute value, this absolute value being able to be in a range from 15 mm to 20 mm.
  • the end radius 7 can be designed for the support cable with a diameter of 4mm to 8mm in a range of 9mm to 18mm in its absolute amount.
  • an external fuse 10 can be provided.
  • This safety device 10 also facilitates the assembly of the support cable 1, 2 in the link guide 3.
  • Both the inlet and the outlet of the link guide 3 are formed in a secured design by the angles ⁇ and ⁇ already described above for the support cable 12.
  • the design of the support device 1, 2 preferably consists of a light metal or a light metal alloy.
  • Support cables 12 which are used in door leaves 11, preferably consist of torsion-free, pre-stretched steel cables.
  • FIG. 10 With the representations of the two Figures 10 and 11 the use of the support cable 12 in connection with a door leaf 11, which is designed as a sectional door, is shown.
  • the representation of the Figure 10 shows the door leaf 11 in its closed position. In the closed position, the support cable 12 is in contact with the link guide 3 and thus essentially encloses the static section Y and the dynamic section X of the link guide 3. If this door leaf 11 is raised by the winding of the support cables 12 over the pulleys 20, the result is the opening position of the door leaf 11 after Figure 11 .
  • the door leaf 11 is in an essentially horizontal position. As a result, the support cable 12 is lifted from the dynamic section X of the link guide 3, and the contact with the static area Y always remains.
  • the support cable 12 dips back into the groove 9 of the link guide 3 and thus gets back into contact with the curve of the link guide 3 and thus occupies the dynamic section X of the link guide 3.
  • the support cables 12 always make contact with the link guide 3 in its static section Y.
  • the bottom side of the door leaf 11 is closed off by a floor profile 31.
