Description

The invention relates to a lifting door, comprising an arrangement of a plurality of movable in a vertical guide, horizontally extending, tensile and radially articulated connected slats with hinge members, including a sectional door with panels and a drive device, according to the preamble of patent claim 1.

Lifting gates with slats or sectional doors for operational closing and opening of door openings, especially in factories, warehouses or similar facilities are known in the art. Such lifting gates serve the safe, tight, weatherproof and windproof closure of halls and must be able to be moved very quickly from an open position to a closed position and vice versa and, if possible, function noise-free and wear-resistant over a long period of time. Furthermore, such lifting gates are also under the influence of shear forces outside an operational load level, z. B. due to faulty operating conditions or external, havarieartige extraneous conditions, relatively undisturbed and largely free of damage in need of repair work.

The lamellar or panel armor forming the vertically extending door closure generally comprises a number of individual louvres or panels arranged horizontally to the goal plane, which are connected in a hinged and tension-resistant manner on both sides to a hinge band formed by a number of hinge members and by means of rollers running in vertical guide tracks are liftable.

A lamellae lifting gate with hinges on both sides, which are rigidly and firmly attached via screw connections, shows the U.S. Patent 2,092,534 , A similar solution with guided over rollers in guide rails hinge straps on which the slats are fixed and immovable, discloses the U.S. Patent 2,827,115 ,

Slats, which are firmly attached to hinge members, shows the DE 40 15 214 A1 ,

Accordingly, the present state of the art is characterized by a fixed and in the horizontal direction rigidly rigid connection of lamellae with hinge members provided on both sides. Such an embodiment is due to the given rigidity in terms of stability, in particular the influence of wind loads, advantageous, but has the disadvantage that when z. B. damage has occurred by a truck, the gate must be taken out of service regularly and extensive repairs are pending. Such problems also occur in a corresponding manner in sectional doors with vertically moving panels.

Furthermore, a rigid attachment of lamellae to hinge members is not adequately suitable, occurring across the goal plane force components, for example, by manufacturing and assembly side given tolerances or else due to thermal effects to absorb, with the result of unwanted stiffness or a Blocking an associated drive device.

To accommodate loads of the aforementioned type is assumed in known slats lifting gates exclusively on the elasticity of the fin material and the dimensioning of the slat cross-sections, completely regardless of any load goes directly into the fixed and rigid points of articulation between the slat and hinge. In many cases, therefore, an elastic reduction of forces and tensions is not possible, so there is a risk of plastic deformations to permanent malfunction or a complete malfunction.

From the foregoing, it is therefore an object of the invention to provide a lifting gate, consisting of an arrangement of a plurality of movable in a vertical guide blades with hinge members, such a lifting gate on the one hand withstand all the usual static and dynamic loads, on the other hand, but in itself undesirable force effects Destruction of the slats or a malfunction of the entire door is prevented, but at least the cost of a necessary repair due to irreversible damage to the door is reduced.

The solution of the above objects is achieved with a lifting gate according to the features of claim 1, wherein the dependent claims include expedient refinements and developments of the subject invention. In the following, the term "lamella" expressly includes the vertical sliding panels known in sectional doors. The features disclosed in the following description are readily applicable to sectional doors and the panels used in sectional doors within the scope of skill of the art.

At least some of the slats are mounted horizontally displaceable relative to the vertical guide and / or the hinge members and / or have at least one substantially vertically extending predetermined breaking point, wherein the slats by means of end-side plug sections in a latching and / or clamping and when exceeding a predetermined acting on the lamellae Force are solving receiving means anchored in the vertical guide.

The lamellae are therefore both fixed and releasably anchored in the vertical guide, wherein the arrangement between male portion and receiving means is designed so that the connection is released as soon as a force acts on the lamellae, which is greater than a predetermined force. The slats are thus released from the vertical guide, without the vertical guide itself being damaged. This is the case, for example, when, due to a collision of the lamellar shell with a vehicle, the lamellae experience an extraordinarily strong horizontal force. In a normal operation of the lift gate, however, and under normal loads of the lamellae, for example, in the usual wind pressures, the slats are firmly anchored within the vertical guide.

The receiving means are carried out in an advantageous manner as an arrangement swing-out holding components that allow a partially perpendicular to the surface of the lamellar succession sliding out of the plug sections. In order to avoid excessive and possibly permanent local bending of the slats in a sliding out of the slats on the vertical guide. If a central impact hits the lamellar shell and the lamellae present there deflect, the lamellar ends anchored in the receiving means are unscrewed by a corresponding angle and then slide out of the vertical guide. The only bending radius occurring at the corresponding lamella thus corresponds to the bending of the lamellae in the central part of the lamellar armor, this bending being completely reversible given a suitable choice of lamellar material.

The end sides plug-in sections have displaceable and in a first embodiment by means of a spring tension fixed in position components. The plug-in sections are thus made flexible and thus support the process of sliding out of the slats from the receiving means, wherein the spring tension is used to ensure a necessary for the normal operation of the lifting gate mechanical stiffness of the plug section.

Accordingly, the receiving means adjustable and fixed in a first embodiment by means of a spring tension components, which hold the corresponding plug-in sections with the necessary stability in a normal operation of the lifting gate and release as needed.

In one embodiment, the end-side plug-in sections are designed by latching members with a latching nose and the receiving means by latching receptacles with a latching lugs surrounding the latching lugs. The locking lug engages latching in the latching bay, the latching bay releases the latching lug, if appropriate, from this clamping connection.

Conveniently, the locking members are slidably disposed in a terminal attached to the slats receiving sleeve, wherein a compression spring pushes the locking members in the direction of the locking receptacles. This configuration ensures both a flexible mounting of the individual locking member, as well as the necessary stability of the connection between locking member and locking receptacle.

In an advantageous extension of this embodiment, the latching receptacle is designed in two parts and consists of movable, the latching bay enclosing and swing out of the plane of the lamellae legs. In this embodiment, the latching lug of the locking member presses against the flanks of the latching bay, wherein the legs of the latching receptacle open, release the latching bay and the latching lug slides out of the latching receptacle.

In a further embodiment of the receiving means, a guide track is formed from pivotable receiving jaws lying substantially parallel to one another. The receiving jaws lie in the vertical guide of the lamellar armor above each other and form an arrangement of a sectionally out of the plane of the lamellae swing out rail.

In connection therewith, a further embodiment of an inserted between the receiving jaws male portion is possible, in which this is formed by a slidably mounted in a receiving sleeve and pushed out by a spring in the direction of the vertical guide slide pin. To increase the rigidity and to prevent unintentional or unauthorized Aushebelns or breaking up of the laminated armor along the arrangement of receiving jaws and sliding bolts rigid and the pivot points of the receiving jaws blocking end pieces are provided at optional locations, preferably in a bottom or lintel area of the lifting gate, the are inserted between the receiving jaws. In a further embodiment, the receiving means, in particular the receiving jaws, formed by a half-frame of two swing-out angles.

In an advantageous embodiment, sliding bolts and end pieces have recesses for receiving a noise-damping wear or sealing strip, such that a chafing, Rattling or concomitant wear of the slats prevented in a rolled-up state.

Advantageously, the belt is supplied only during the Aufrollvorgangs the lifting gate. For this purpose, in the vicinity of a winding shaft rolling up the lamellar shell, there is a deflection shaft which feeds and positions the band, with the aid of which the band is wound between the rolled lamellae.

As Aufschiebeschutz, the lift gate on a locked by a driver in a closed lamellar crash lintel. In an electromotive opening of the driver releases the lintel and opening the lift gate is possible.

In a further embodiment, the receiving means is designed as a connected to a flexible hinge band adapter with a wedge tip receptacle and the plug portions formed as a wedge tip in the wedge tip receiving wedge tip. In this case, in an advantageous embodiment of this embodiment, the wedge tip is fixed in the wedge tip receptacle by a tensile force by means of a tensioning cord guided through the adapter and fastened to a tensioning cord lock located on the wedge tip.

The tensioning cord is guided and / or wound in an advantageous manner via a deflecting roller device arranged in the vertical receptacle. Conveniently, the tensioning cord is further tensioned by means of a tension spring, which may be in particular a part of the Umlenkrolleneinrichtung or terminally engages the tensioning cord.

In addition, the wedge tip can be pressed by a compression spring in the wedge tip holder, whereby the stability of the arrangement is increased.

The lifting gate according to the invention will be explained in more detail below with reference to exemplary embodiments. To clarify serve the attached figures. It shows:

One in the 1a and 1b shown exemplary first embodiment of a receiving means and a plug-in section consists of a respective end secured to at least a few Hubtorlamellen locking member 10 , by means of a catch 15 in a snap-in recording 20 is engaged. The snap-in receptacle 20 is in the embodiment of 1a and 1b designed in one piece, wherein the latching lug of the locking member of a rest bay 25 is enclosed. The latching lug does not necessarily have to be clamped within the latching bay, but may be slidably mounted in the latching bay in the vertical direction. In the case of a clamping attachment of the latching lug within the latching bay, the latching receptacle forms a component of a hinge running in a vertical guide, wherein the latching receptacle is moved with a vertical displacement of the laminated armor with the corresponding latching members and thus the slats.

In the case of a sliding mounting of the locking lugs in the locking bay, the locking lugs are moved substantially all lamellae by a fixed and immovably installed locking receptacle in a vertical movement of the lamellae successively. Such a sliding bearing has the advantage that the lamellar armor does not have to be associated with a latching receptacle for each lamella, which reduces the material and production costs involved in the installation of the arrangement.

In such an embodiment, the locking member in the horizontal direction and tensile forces below a certain size is firmly locked, the maximum male horizontal force substantially by the ratio between the size of the latch and a constriction 14 is determined in the locking receptacle and by the elastic material constants of the locking receptacle. If a horizontal force exceeds a predetermined size, the detent pushes 15 the narrowing 14 apart and thus bends the locking receptacle 20 on, wherein then the locking member 10 from the snap-in receptacle 20 also occurs.

Such an arrangement forms the simplest embodiment of a receiving means connected to corresponding plug-in sections. The maximum horizontal traction, which just absorbs the locking receptacle can be increased in any way by the constriction 14 is made sufficiently small. However, this is an increasing rigidity of the locking receptacle 20 connected. If a strong central force acting on the lamellar armor acts on the lamellar armor, the rigid connection between the latching lug and the latching receptacle leads to strong local bending of the lamella near the latching member before the latching member slides out of the latching receptacle. There is no possibility in this embodiment that the locking receptacle initially follows the bending of the blade and then releases the locking member. For this reason, such an embodiment is advantageous for very flexible slats or lower horizontal tensile forces, if a permanent deformation of the slat should be excluded.

In the 2a and 2 B various exemplary embodiments of locking members are shown in a side view. In the in 2a The embodiment shown detent nose 15 from a catch cylinder 16 located at the endpoint of a substantially prismatic bridge 11 located. In the embodiment of 2 B the catch 15 as a detent ball 17 running on the top of a cone 12 is arranged.

A more flexible design of the arrangement of locking receptacle 20 and locking member 10 is in the 3a and 3b shown. In the 3a illustrated embodiment has a locking member 10 on that in a snap-in 20 is plugged in, the rest bay 25 compared to the embodiment of the 1a and 1b no constriction 14 has and seamless in an expansion 17 passes. The catch 15 is made rectangular in the embodiment. The locking member 10 is in the embodiments of 3a and 3b in a receiving sleeve 30 inserted and is by means of a compression spring 35 attached to a compression spring receptacle 31 is counter-bearing, in the direction of the locking receptacle 20 pushed. In this embodiment, the maximum holding force between locking receptacle and locking member is essentially by the spring constant of the compression spring 35 certainly. The locking member is thus also connected to the lamella more flexible than in the previous embodiments.

At a maximum, exceeding a predetermined upper load limit bending force on the lamellae, the latch slips without an additional resistance from the latching bay, the latching member is separated from the latching receptacle rucklos. Once the latch is slipped out of the latching bay in small pieces, the locking member can perform an angular rotation perpendicular to the plane of the lamellar armor and a local strong bending of the slats in the vicinity of the locking member is avoided.

In the exemplary embodiment in FIG 3b is the snap-in receptacle 20 designed in two parts and has a leg 26 , a thigh 27 and two pivot points 28 for the storage of the thighs 26 and 27 on. The pivot points allow picking up and yielding against forces that act both parallel to the lamella longitudinal axis, as well as perpendicular to this axis and thus allows entrainment of the locking receptacle in a lamellar bending, hereby strong local bending can be largely excluded. The position of the pivot points decisively determines the rigidity of the locking receptacle 20 opposite vertical and parallel to the lamella longitudinal loads occurring.

In the figures, two exemplary fulcrum layers are shown in FIG 3b and in comparison in 4a shown. The pivot points 28 in 3b are very close relative to a direction perpendicular to the longitudinal axis of the slats radial direction of the locking lug 15 , in the 3b is indicated by a dashed-dotted line with the reference symbol A. A force component acting in the direction of this line causes a smaller pivotal movement of one of the legs 26 or 27 and a stiffer configuration of the split locking receptacle, the closer this line is with respect to the fulcrums. Are the pivot points 28 perfectly on the line A, a lateral pivoting of the legs is practically impossible. At the in 4a embodiment shown are the pivot points 28 very far away from the line A. Such an embodiment very easily detects force components acting in the direction of the line A. This means that such an arrangement of the legs 26 and 27 can be opened accordingly easily. The lamellae can thus be pressed in relatively easily. In a convenient choice of the location of the fulcrums 28 is an embodiment of the Divided locking receptacle possible, in which without a spring tension of the legs 27 and 26 both a sufficiently rigid and a correspondingly flexible connection between locking member and locking receptacle can be ensured.

An exemplary embodiment of the split locking receptacle 20 with thighs 26 and 27 should in the following on the basis of 5a to 5d in conjunction with which an exemplary disengaging operation will be described.

In the starting position, shown in 5a , there is the catch 15 of the locking member 10 between the thighs 26 and 27 the catch receptacle. The locking member itself is slidable in a receiving sleeve 30 stored, wherein a compression spring 35 pushes the locking member in the direction of the locking receptacle.

At an in 5b schematically shown acting on the lamellae frontal force is the catch 15 by a certain amount against the lower leg 27 pressed, with the lower leg turns out at an initially small angle from the plane of the lamellar armor. At the same time it is also the rest area surrounding the detent bay 25 open and the thighs diverge. The catch is initially still on the lower leg 27 and forms a fulcrum for the bending occurring under the load on the lamella. The locking member is thereby pushed back into the receiving sleeve.

In the further opening sequence, the lower leg 27 under the influence of the external load further out of the plane of the lamellar armor until the rotation reaches an end point. In 5c this endpoint is by striking the lower thigh 27 against the upper thigh 26 Are defined. In this position, the locking member 10 first pressed further into the receiving sleeve, wherein in the course of the locking lug slips out of the now released Rastbucht, as in 5d is shown. The blade has then released from the locking receptacle and thus slides out of the vertical guide.

Another exemplary embodiment of a receiving device is shown in FIG 6 shown. 6 shows an arrangement of pivoting receiving jaws 40 within a doorstep 60 , The receiving jaws are at hinge points 28 pivotally fixed to the door support and optionally by means of a compression spring 46 held in a defined rest position. The receiving jaws of vertically superimposed receiving devices after 6 form a guideway, in which the lamellae moves when opening and closing. As in the previously described embodiment, the slats have end-side receiving sleeves 30 on. These take in the in 6 illustrated embodiment a sliding bolt 45 on, by means of a compression spring 35 in the direction of the gatestop 60 is pressed. The receiving leg and thus the entire guideway are expediently minimally over in relation to a wall, whereby a risk of damage when starting up is minimized. When the lamellae are triggered, the receiving jaws pivot, with the sliding bolt sliding out of the guide.

Unintentional or unauthorized pressing of the lamellar armor in a closed position becomes one of the hinge points 28 out 6 blocking device off 7 by means of end pieces 50 prevented, which are located at selected positions or slats of the lamellae.

In a further embodiment of a receiving device, this is according to the 8a to 8c by an arrangement pivoting angle 70 and 71 educated. The angles 70 and 71 are at pivot points 28 stored and are by means of springs 72 held at one of the two angle legs so in a rest position that the legs of a pointing in the direction of the lamellae substantially semi-open rectangular receptacle for a sliding slider 75 form. The slider 75 rests in a receiving sleeve 30 and is by means of a compression spring 35 in the direction of the angle 70 and 71 pressed. It has a conical or conical section 76 on. As with the in the 7 and 6 In the embodiment shown, the angles form a guideway and are each designed as a substantially continuous guide rail. Alternative to the springs 72 can also torsion springs at the pivot points 28 be arranged.

When a compressive force acting on the lamellae, the receiving sleeve moves 30 in the direction of one of the two angles 70 or 71 and the slider 75 pushes it against the one of the springs 72 applied force laterally out of the guideway, as out 8b can be seen. By partially swinging out larger local bends are avoided on the lamellae near the vertical guidance of the lamellae.

Under the external pressure, the slider slides on an angle leg along the conical or conical portion 76 from, wherein the slider is pressed into the receiving sleeve. Finally, as in 8c it can be seen, the slider pressed maximum in the receiving sleeve, wherein the angle 71 under the influence of the spring 72 back to the starting position and the lamella is released from the guideway.

The individual slats of the lamellar armor are hinged together. When winding the lamellae, the slats lie on each other and consequently rub against each other. In order to prevent scratching of the slats, according to the exemplary illustration 9 a sealing tape 80 of a wear-resistant and noise-damping material by a suitably in the vicinity of a winding roll 82 arranged pulley 81 precisely fed. Like from the 6 and 7 can be seen, have the sliding bolt 45 , or the end pieces 50 wells 41 on. The sealing tape is passed through the pulley 81 advantageously inserted into the wells. When winding the laminated armor are thus by the winding roll 82 in each case a lamellar layer and a layer of the sealing tape placed thereon are wound into one another. In the rolled-up state, the lamellae are thus not directly adjacent to one another, but are kept at a distance by the sealing strip and thus do not rub against one another.

Between the lamellar shell and the lintel there is a lintel seal 83 , which serves as Aufschiebeschutz with a closed lifting gate. For this purpose, a driver on the end piece closes the lintel seal in an almost closed lift gate.

Opens the gate by electric motor, the driver releases the lintel, which is removed by a compression spring from the winding lamellar armor.
