Definitions

  • the invention relates to a lifting gate with a lamellar armor which can be moved vertically upwards in guideways from a closed position into an open position of a gate opening.
  • a rolling door is known as the vertically opening closure of a door opening that can be walked on or driven on, which conventionally essentially consists of a roller shutter consisting of mutually angled slats which are guided into the closed position on the two side edges of the door opening by vertical guide rails , a winding shaft, to which the roll armor is fastened and by means of which the roll armor is raised and wound up into the open position, an electric motor drive, and a safety device which prevents the roll armor from falling if the drive fails.
  • the roll armor as the protective part of a roller shutter that closes the door opening, consists of hinged slats, usually profile parts, for example extruded aluminum materials.
  • the height of the individual slats is usually about 80 to 120 mm.
  • These profile parts are mostly provided as slide-in profiles which, due to their shape, are connected to each other in an articulated manner without further connecting members to form the roll armor.
  • the joint In a typical aluminum extruded profile, the joint is designed, for example, as a pan and web, so that in the case of profiles pushed into one another, the joint formed in this way is the same as when the roll is rolled up. armor forces can absorb and endure.
  • the connection of the lamellas formed into a joint generally has a large amount of play.
  • the shape of the nested profiles should be designed in such a way that dirt and water are prevented from being deposited in the joints, and sufficient tightness against wind attack is ensured.
  • the bale layers on the winding shaft are formed by the interconnected profiles, which have a certain profile height. Each profile lies on the most protruding edge of a profile of the layer below.
  • the direction that a profile takes in the cross-section of the bale within its bale position depends on the point of contact of the profile. Due to its random position, it in turn determines the arrangement of the next profile connected to it. This results in an irregular position arrangement of the individual roller shutter profiles when the bale is wound up. It follows, among other things, that, for example, only a single edge of a single roller door profile supports the entire load of the still freely hanging armored part, which can result in considerable edge pressures.
  • head pieces or end pieces are generally attached to the side of the roller shutter profiles, which run in corresponding vertical guide rails with a generally U-shaped cross section.
  • These vertical guides are funnel-shaped at their upper inlet, so that the roll armor can run smoothly into the vertical guide when it is unrolled, without the risk of getting stuck.
  • the roll armor is attached with its initial profile to the winding shaft so that the attachment when closed
  • the roll armor rolled up on the winding shaft lies in the lintel area of the door opening.
  • the drive is usually protected behind the lintel and therefore cannot be damaged by vehicles when the gate is being driven.
  • An electric motor is usually provided as the drive, with a manually operated drive for makeshift operation.
  • the roller shutter shaft is driven at a constant speed, ie at a constant angular speed.
  • the roller armor attached to the shaft is raised and wound onto the shaft.
  • the decisive factor for the lifting speed is first of all the effective winding radius, which is continuously increased during winding, since the lower parts of the roll armor lie on the already wound upper parts. Since the lifting speed changes in direct proportion to the radius of the ball, a roller door initially runs slowly upwards in order to become faster and faster upwards. If the kinematic conditions are considered in more detail, taking into account the thickness and height of the profiles, the roller shutter door must be regarded as a polygon. Lie down when winding up the profiles first on the round winding shaft.
  • the straight profiles form a polygon on it.
  • the corners of the polygon are further away from the center of the wave than the centers of one side of the polygon. If the shaft of the roller shutter rotates at a constant angular speed, the roller shutter is pulled up once with a lever arm corresponding to the length of the corner point of the polygon and the stroke speed corresponding to this lever arm length, and in the next moment with a length to one side of the Lever arm corresponding to polygons and the stroke speed corresponding to it.
  • the stroke speed is directly proportional to the lever arm that is effective, discontinuous and random, and is therefore characterized by correspondingly strong and sudden fluctuations when the roll armor is rolled up.
  • the accelerations and decelerations of the masses of the unrolled roll armor act as vibrations. These vibrations also act on the structure via the winding shaft, so that when the structure is statically calculated, care must be taken to ensure that the natural vibration number remains outside the rolling gate frequencies. Otherwise, the lifting speed of the roller shutter must be drastically reduced. With constant angular velocity of the roller shutter shaft as the roller gate bale becomes thicker, the frequency of the vibrations increases and its amplitude decreases. Conversely, this means that the sound generation when the roller shutter is actuated increases the further the roller shutter comes down.
  • the entire load of the roll armor may only depend on a single profile of the profiles still on the shaft.
  • the tensile force of the entire internal tank load does not lie in the door plane, but in the straight connection from the lower part to the effective bale radius.
  • the roll armor will therefore deform in the middle between the guides in order to approximate the course of the tension as much as possible.
  • the profile ends are held by the guides and cannot follow the tension line.
  • the above-described unfavorable kinematics of the rolling shutter which has been known in its basic features for more than a hundred years (and so far has hardly been changed), is to be seen as the main reason for a high level of noise during running, and ultimately also for the insufficient fast-moving property of the rolling shutter.
  • the running noises originating essentially from the profile joints occur mainly when the roller door is moving upwards and then particularly strongly in the lower third of the door opening, provided that the roller door has a "normal extension".
  • the noises occur in the vicinity of the bushing, where the profiles bend, are subjected to high tensile forces and are said to rotate in the joints.
  • roller doors with a full-surface door leaf made of flexible material that can be wound onto a winding shaft or winding drum have also proven to be an additional opening closure.
  • roller shutters also offer the advantage of optical transparency if the flexible material is selected appropriately. Macrolon films or soft PVC films, for example, are widespread. However, this advantage over opaque material is lost over time, since the optical transparency is adversely affected by the penetration of dust and the like when the film is wound up and the scratching of the surface associated therewith.
  • the films in this type of roller door must be as thin as possible, since the winding diameter as a whole would otherwise be too large.
  • the provision of thinner foils also enables the door leaf to run faster due to the easier winding.
  • the small thickness of the foils, and accordingly the low weight of the door leaf leads to reduced wind resistance. To remedy this, it was proposed to provide additional weight in the form of an end profile arranged at the lower edge of the door leaf, or spring-loaded tension belts which run over deflection rollers mounted on the floor.
  • a conventional sectional door essentially consists of a tank with comparatively high sections, which can be folded down from a vertical closed position into an upper horizontal position below the ceiling by means of a cable drive.
  • sectional doors also makes it possible to provide lightweight gates made of aluminum sections, which are filled with a plastic material for heat and sound insulation, for example, in order to be able to open and close garage doors even with larger door widths without an additional electric motor drive, however, only by hand.
  • the individual sections lie flush with one another in the closed position, so that the entire end face of a section is available for the seal.
  • the sectional door thus appears to be cleanly closed. senes gate with a continuous outer surface, with no gaps in between.
  • a further improved tightness is achieved, for example, by rubber inserts which are pressed together in the closed position by the sections lying one above the other.
  • the sections have a bulge extending across the entire width of the door on one end face, which engages in a corresponding recess in an adjacent section when the sections are pivoted into the same plane as a tongue and groove connection, thus increasing the mechanical strength of the door leaf against wind ⁇ pressure is further improved even with large door widths.
  • the sections are connected by means of a plurality of individual hinges, which are attached at certain intervals across the entire width of the gate in such a number that sufficient strength and support is achieved.
  • the hinges attached to the side edge of the sections are generally designed at the same time as a holder for a roller which can run in a guide rail with a U-shaped cross section at the edge area of the sectional door. Since the individual hinges are attached to the sections in such a way that the sections can be folded away towards the inside, problems arise in so far as the protruding parts of the hinges attached and projecting on the inside of the door are visually disruptive and dangerous. A further risk of injury to sectional gates arises when the sections bend due to the open gaps that occur or when the sections are folded back and the gaps are closed.
  • sectional doors with relatively high sections arises in connection with the curved guide part above the lintel area, where the individual sections are folded down from the vertical position into the horizontal position. This folding naturally leads to sudden tipping accelerations and accordingly, when operated quickly, considerable force is exerted on the individual sections.
  • the generally uneven force curve due to the planar formation of the lamellae with finite height, which in the cam track web in the manner of a polygon leads to the fact that sectional doors can generally only be operated at lower running speeds, without the risk of an increased noise level.
  • a cable pull device with pull cables and support cables, as well as cable drums arranged on a drive shaft, are generally provided.
  • the suspension cables are wound onto the Sai-it drums, while at the same time the pull cables unwind from the cable drum.
  • the traction cables are wound up and thus pull the door down, while at the same time the suspension cables are unwound from the cable drums without becoming slack.
  • the drive of the The drive shaft takes place via an electric motor which is arranged, for example, directly below the ceiling.
  • torsion springs are provided for balancing the door leaf weight, which are arranged coaxially to the continuous drive shaft. In the closed position of the door, the torsion springs are fully tensioned and are relaxed accordingly when the door leaf is raised. These torsion springs are subject to increased wear and are therefore considerably limited in their service life. Particularly when the direction of movement of the sectional door is reversed frequently and suddenly, the torsion springs suffer considerable dynamic tension peaks due to the jerky movements. Due to the failure of the torsion spring, the maintenance and replacement work associated with the sectional doors is naturally time-consuming and cumbersome.
  • the invention has for its object to provide a lifting gate which enables rapid opening with low noise when opening and closing the gate, and which in the closed state offers sufficient tightness against wind and weather attack and security against unauthorized opening, and also requires only a small amount of space above the lintel, even with larger door heights.
  • the two guideways which are each arranged on the two opposite sides of the gate opening, are designed such that, starting from a vertical section running approximately vertically over the height of the gate opening, the two Guideways at the inlet of the lifting gate open into a spiral section that runs inwards. This ensures that the required space for the slat armor in the open position in the depth of the door is kept as small as possible, even with a larger height of the door opening, without requiring a significantly increased space requirement in the height above the lintel.
  • the slat armor in the open position of the lifting gate, can be moved into the spiral section of the guideways in such a way that the plurality of slats are in a spiral path and are completely contact-free with respect to one another, so that no frictional or compressive forces occur on the slats and thus considerable running speeds of the Hub ⁇ gates are made possible without excessive noise.
  • the slats of the slat armor covering the width of the door opening are designed such that they can be angled relative to one another and are made of rigid material, so that the lift gate is sufficiently closed in the closed position has great mechanical stability in order to withstand even greater wind loads and to ensure security against unauthorized opening.

  • the geometric hinge axis 36 comes to lie completely within the area which is delimited by the two outer main surfaces 38 and 40 of the lamellar armor 12.
  • This position of the hinge axis 36 ensures that the width of the angular opening between the adjacent lamellae 14 when it is bent of the slat armor is reduced to a minimum, so that the tilting accelerations are correspondingly reduced when entering the upper, bent guideway. As a result, the possible running speeds of the lifting gate shown are further increased without being accompanied by excessive noise.

  • the sealing strips 42 engage in the slats 14 with only a little lateral play in the direction perpendicular to the door leaf plane, so that the slat armor 12 is put under tension at a certain point when pressure is applied, and corresponding restoring forces act immediately against the pressure load.

  • the spiral section 10 in accordance with the exemplary embodiment shown in FIG. 1, has the three arc sections 56, 58 and 60. As shown, part of the arc section 60 lies directly against the arc section 56, so that the inside radius of the arc 56 corresponds approximately to the outside radius of the arc 60. The outer radius of the arc 58 corresponds to the outer radius of the arc 56.

  • This radius is the same here chosen that, depending on the distance d between adjacent hinge pins (see FIG. 3), it is possible for the lamellar armor 12 to run properly into the spiral section 10 without, for example, fear of self-locking of the angled lamellas in the narrowest arc section got to.
  • Such a self-locking would occur at the latest if, when the lamella armor 12 runs in, the force component directed parallel to the guideway to overcome the rolling friction at any point on the guideway becomes smaller than the rolling friction component acting accordingly at this point, which in turn is proportional to the normal force present at this point.
  • the smallest possible arc radius is already limited by the fact that the sealing strips are bent when the slats are bent, which creates restoring forces that have to be overcome by the drive of the lifting gate, and which are all the greater, depending. the guide arc is chosen more narrowly.
