Definitions
- the invention relates to a single-leaf overhead door with the features of the preamble of the appended claim 1, as it is known from FR 1 197 711 is known.
- the DE 16 92 017 U1 describes how the FR 15 21 631 C1 , a tilting gate with a rigid door leaf, the upper area is articulated via levers to a frame and which is guided below the Hebelanlenkung on rollers or the like guide elements mounted on the frame vertical guide rails.
- the guide elements are articulated at a distance from the lower door leaf edge at the side door leaf edges.
- fall arresters responding to a slack rope in other types of doors can be found in the DE 195 03 588 C2 and the DE 27 27 440 A1 for overhead doors, the EP 0 172 351 B1 for sectional doors, the EP 0 149 692 A1 and the EP 0 156 415 A1 for roller shutters, the DE 37 10 237 for sectional doors, the FR 24 15 188 A1 for sectional or lifting gates and the DE 44 13 465 A1 for sectional, lifting or rolling gates.
- the from the EP 0 156 415 A1 and the DE 37 10 237 A1 Removable sectional doors continue to have as weight balancing a mounted above the door opening massive Torsionsfederwelle with two torsion springs.
- the DE 92 02 302 U1 describes a single-leaf overhead gate with a gate frame and a rigid door leaf, which is guided with its lower portion on a first of the frame associated substantially vertical guide rail and with its upper portion on a second of the door frame associated substantially horizontal guide rail such that tilts the door leaf in the course of movement between its horizontal opening position and its vertical closed position as a whole.
- a power source for the weight balance also acting on a cable counterweight device is provided.
- FR 1 197 711 is a single-leaf overhead door with a rigid door leaf, which is guided by a frame, from a substantially vertical closed position in a substantially horizontal opening position as a whole can be tilted upwards, known.
- the door leaf is guided at its lower part with rollers and at its upper part via levers.
- a torsion spring shaft is provided with a single torsion spring.
- the torsion spring shaft is designed as a hollow shaft and rotatably mounted at its two end regions in ball bearings.
- a cable drum of a cable pulling device is provided on the outside in each case. In each case a Jerusalemwickelbares on the cable drum rope transmits the tensile force on a pawl having fall protection device on the door leaf.
- a single-sheet overhead gate referred to in the preamble of claim 1 is further developed by the characterizing features of claim 1.
- the torsion spring shaft must be made particularly compact for the arrangement described here.
- the possible torsion spring (s) may or may not have a large diameter.
- the load on the torsion spring is completely different than, for example, a sectional door.
- the weight force of the goal to be equalized is the same throughout the entire course of the goal. For this reason, it has been used in many previously known gates of this type, no torsion springs as a counterbalancing device, but counterweights, since their force remains the same, while the spring force of counterbalance springs constantly changes during door travel.
- the torsion spring arrangement of the gates considered here must be effective over a long torsion range, for example more than 20 revolutions: e.g. the torsion spring is pretensioned by about 30 revolutions by the manufacturer.
- the Torsionsfederbelastung is therefore particularly high here just at the beginning of an opening movement.
- a solid rod was used as a torsion spring shaft to achieve the compact dimensions. Due to the torsion spring load, such a shaft has bent heavily and carried out an egg movement "like a sausage", which has led to restless running, shortened life and unwanted noise.
- the torsion spring shaft is now completely designed as a hollow shaft.
- the door shaft is thus formed by a tube.
- Such a tube has the same mass a larger outer diameter and a larger resistance bending moment than a solid shaft.
- a lower deflection reduces the bearing load and thus prevents a safety-relevant failure of the counterbalancing device even with prolonged and frequent operation without maintenance. Nevertheless, can be dispensed with additional support bearing.
- the torsion spring is biased at sectional doors conically.
- An eggs to the extent as in the here in question overhead doors with inventive compact preassembled power source unit does not occur there.
- sectional doors are pre-assembled in parts and not to the extent that delivered here in question single-leaf overhead doors.
- the largest possible pipe diameter would be desirable. However, this is offset by the available limited dimensions, because the tube must be able to engage in the torsion spring and this should have a diameter smaller than the height or width of the parallel Zargenholmes.
- the storage of a thick pipe is problematic, because this would result on the one hand for the required compact arrangement too large bearing elements, on the other hand, but also with the diameter increasing bearing friction forces.
- the shaft ends are mounted and thus the end portions of a tubular profile having a Torwelle made thinner than its extending between the bearing elements central portion.
- the training with thinner and thicker sections is possible in various ways.
- the door shaft is integrally formed with conical transition regions between the sections of different diameters.
- the door shaft is assembled from pipes of different diameters, wherein, for example, one end of a thinner pipe is inserted into a thicker pipe by means of a (wedge) toothing rotation in a thicker.
- splines other non-rotatable connections (welding, splint connections, ...) for the tubes of different diameters are conceivable.
- the tube profile also does not have to be circular over the entire wavelength, it could also stability reasons at least in sections, other tube profile shapes (square, star-shaped, with reinforcing approaches, ...) are used.
- a torsion spring shaft is used as weight compensation device.
- the torsion spring shaft can already be pre-assembled preassembled at the manufacturer.
- the installer only needs to align the door, which is already preassembled in the frame, and anchor the frame in the masonry in order to obtain a ready-to-use gate.
- the safety of a second torsion spring is not required, which also saves weight and costs. This is surprisingly possible in the overhead door without loss of security, because the fall protection device not only reacts to a cable break but also to a spring break.
- the torsion spring shaft itself is space-saving attached to the frame. This allows a pre-assembly of the torsion spring shaft at the manufacturer, so that uncertainties due to incorrect installation and the risk of injury to the assembly personnel, e.g. when tensioning the spring, can be reduced.
- a preassembled drive unit acting as a drive shaft with a door shaft and cable drums be used as the power source.
- This Torwelle is designed as a torsion spring shaft of the torsion spring counterbalancing device. This saves weight and thus transport costs;
- the torsion spring shaft can already be pre-assembled preassembled at the manufacturer.
- the installer only needs to align the door, which is already preassembled in the frame, and anchor the frame in the masonry in order to obtain a ready-to-use gate.
- the door shaft itself is stored space-saving on the frame.
- the drive unit consisting of torsion spring shaft and at least one traction mechanism drum is dimensioned in height and width direction such that it protrudes beyond the frame neither toward the side nor upwards or into the door opening framed by the frame in the direction parallel to the frame plane. It protrudes only in the thickness direction in the space to be closed, but otherwise uses the space also required for the frame. To this Way, the fully preassembled door can be transported to save space and fitted without difficulty and without the need for subsequent installation and the associated safety risks by incorrect assembly at the site in the masonry opening to be closed.
- a biasing spring for biasing the pawl lever in the detection position under load during door operation is always in motion.
- this spring is claimed in the entire pivoting between the pawl lever and door leaf exclusively on rotation of a spring formed on the coil portion. Loads by constant regional bending of a spring are thus avoided.
- the spring load is distributed over a plurality of turns of a helical region, which rotate with each other as in a tensioned on a helical spring.
- Such a spring design and arrangement has a particularly long life, so that risks are avoided by spring breakage or at least as far as possible contained.
- Another - albeit less preferred - embodiment according to not to store the pawl lever directly to the door leaf, but on a pivoting relative to the door leaf pawl holder.
- the biasing spring is not moved in the door movement, since the biasing spring must be effective only between the pawl holder and the pawl lever.
- the tilting or pivoting movement of the door leaf causes a pivoting of the pawl holder relative to the door leaf.
- the Tor Gays Trial of the interior of the garage further outwardly offset - the lower door leaf edge pivots outwardly in the course of the opening movement - so that more space is available, for example for parked cars in the interior of the space to be closed.
- the attachment of bearing elements of the torsion spring shaft is e.g. directly on the upper frame spar.
- the dimensions of the torsion spring shaft, i. in particular its outer diameter (if necessary. Also that of the cable drums) is more preferably such that it does not protrude beyond the Zargenholme and that neither outwardly nor inwardly toward the door opening.
- Fall protection devices have hitherto been proposed, at least in part, essentially purely vertically moving door leaves, that is to say, for example, those of ceiling sectional doors, the lower panels of which carry the majority of their movement in vertical guide rails, or of lifting gates, which are guided upwards in their entirety.
- Known fall protection devices comprise housings which are fixedly mounted on the corresponding side door leaf area and in which a pawl is pivotally mounted, which is triggered when the rope slackens - usually via release elements which move out of the range of movement of the pawl when the cable is slack.
- the fall arresters described here advantageously have a pawl element which is pivotably mounted on or parallel to the roll axis about the roll axis and which can pivot relative to the door leaf when the door leaf is tilted and thereby retains its position relative to a stationary engagement formation, which is detected by the pawl in the event of triggering.
- the fall protection device can also be particularly simple in that it comprises a formed on a pawl lever pawl which is biased spring-loaded in the locking or engagement position and which is pulled by the cable tension against this bias to its release position. This can be realized particularly easily by the fact that the door leaf-side end of each cable unit does not attack the door leaf itself, but transmits to the pawl lever and the cable pulling forces on the pawl lever, the pawl pulling into the release position on the door leaf.
- the pawl element itself is designed as a pawl lever.
- This can in turn be formed by an at least two-armed lever, wherein a lever arm is designed as a pawl and has a engagement formation in the blocking position engaging engagement portion and the second lever arm has an attack on the cable pulling device.
- a lever arm is designed as a pawl and has a engagement formation in the blocking position engaging engagement portion and the second lever arm has an attack on the cable pulling device.
- the pawl member may then be formed by only a single movable part, namely the pawl lever.
- the roller axle is generally parallel to the door leaf plane and preferably also defines the tilting axis for the door. Due to the mounting of the pawl lever just on this axis can be this hold in its release position, for example, in vertical or slightly inclined to the vertical release position during the entire Torblattieri. If the rope becomes limp, then the pawl lever moves through the spring preload in the blocking position and then engages in the engagement training, so that the door leaf is still held on its roller axis in the event of triggering.
- the engagement training can be particularly advantageous and easy train directly on or in the guide rail for the rollers.
- a region of the guide rail which is parallel to the door opening plane and forms a path for a roller can be provided with the engagement formation.
- a series of openings is simply provided on the entire course of the guide rail parallel to the gate opening plane area, wherein the engagement end of the pawl is designed correspondingly terminated with an acute angle so that this end in released by slackening of the rope pawl in the next opening as seen in the direction of fall is introduced and secures the door leaf against falling there.
- a cable attack is preferably not centrally provided, but off-center, at the engagement training in normal use applied longitudinal half of the two-armed lever, which forms the pawl.
- This eccentric arrangement ensures a tight rope for the application of torque to the pawl, against the bias.
- the eccentric arrangement would be equivalent to a corresponding bending of the lever arms to each other or a corresponding displacement of the lever axis on the pawl lever body.
- the eccentric arrangement is the simpler manufacturing because of space reasons and currently preferred.
- the bias itself is chosen so that it provides sufficient voltage to trigger the pawl throughout the pivoting or tilt angle range of the door leaf, but never becomes so large that it can not be overcome by the cable tension.
- In the upper area may also be provided a cover to cover the uppermost opening or the uppermost openings against engagement of the pawl.
- the gate remains functional even with a slight decrease in the torsional spring tension or worse tuning, yet the manufacture of the guide rail as a piece of an endless profile with a continuous series of openings is industrially advantageous possible.
- the guide rails left and right identically designed and thus easier to manufacture industrially. Left they are then placed opposite the right arrangement on the head attached to the frame, for example. Welded.
- an engagement member against engagement by the pawl.
- an engaging part which may be formed, for example, by a clip-on clamp, could also be designed such that it acts as a kind of catch for the roller for holding the door leaf in the uppermost position and for providing a noticeable for the operator the opening position marking detent threshold acts.
- the pawl or a pawl lever exhibiting these is not mounted directly on the roller axis, but indirectly via a pawl holder, which in turn is preferably itself pivotally mounted on the roller axis.
- the pawl holder can thus always maintain the same position for engaging training throughout the movement sequence of the door leaf.
- At the pawl holder can then be provided in accordance with any design as appropriate described above pawl lever or other locking device. It would also be possible, for example, to provide on such a pawl holder a triggering of the rope causing bolt, which engages in stationary abutment.
- preloaded pawl is provided, which is pulled by the cable tension against this preload in its release position.
- the pawl is formed on a two-armed pawl lever, wherein the first lever arm forms the pawl and, for example, also provided with a tapered engagement end and on the other lever arm an attack for the door leaf end of the corresponding Seilzugisme is provided. Due to the pawl holder on which this pawl is pivotally mounted, a pivoting of the pawl, for example, also form perpendicular to the roll axis. In such a case, the engagement formations can be formed on a region of the guide rail extending perpendicularly to the door opening.
- openings are also provided in which engages the pointed engagement end of the pawl.
- one-sheet overhead gate - here a tilting gate - has a rigid door leaf 1 and a frame 2.
- a tilting gate - has a rigid door leaf 1 and a frame 2.
- lateral vertical frame beams 3 and 4 of the frame 2 are only over a portion of the lateral Zargenholme vertically extending guide rails 5 arranged.
- a Torblattwhenaus occurs at the upper horizontal Zargenholm 6 .
- the guide rail 5 has approximately a J-profile shape, ie a profile shape with a web 5a and two legs 5b and 5c, of which a first leg 5b as the U-legs of a U-profile and substantially perpendicular to the web 5a extending and the second leg 5c as the C-leg of a C-profile forming a roller conveyor is formed channel-shaped curved.
- the series of openings 13 is formed at the same distance from each other in the C-leg 5c.
- the guide rail 5 and thus the ends 5d and 5e are formed relative to a plane perpendicular to the guide rail longitudinal direction center plane of the guide rail 5 mirror images of each other.
- identically designed guide rails 5 on both vertical frame beams 3 and 4 and left and right usable.
- the respective upper end 5d of the left and right guide rail 5 is provided with a clamp 5f which is clipped onto the end 5d, more precisely onto a first elongated hole 5g extending there transversely to the guide rail longitudinal direction.
- the bracket 5f engages with its free, an inwardly bent portion 5fa exhibiting end 5fb by a longitudinally to the guide rail longitudinal direction extending second slot 5h in the formed by the C-leg 5c roller conveyor. Further, at the upper end 5d inside the guide rail 5, a roller stopper formed by a rubber pad 5i having a dovetail-shaped end is provided.
- the door leaf 1 continues to show how best Fig. 4 can be seen, at its two Torblattifierr specialtyn 14 on concentric roller axes 15, which extend parallel to the Torblattebene horizontally mounted rollers 16.
- the rollers 16 are guided in the guide rails 5 for vertical movement.
- the rollers 16 are not arranged on the lower door leaf edge 17, but near the horizontal center line M of the door leaf 1.
- a lever mechanism formed from lateral levers 19 engages the door leaf 1 at its door leaf side edges 14.
- the levers 19 are at one end stationary to the frame 2 in the vicinity of the upper Zargenholmes 6 and the other end to the Torblattifierr selectedn 1 via the guide rails 5 reaching U-profile pieces 35 stored.
- Fig. 1 is the door leaf 1 in its vertical closed position and in Fig. 2 reproduced in its horizontal opening position.
- the rollers 16 are guided vertically upwards within the guide rails 5.
- the door leaf 1 performs a pivoting or tilting movement about the roller axis 15, which is guided by the lever 19.
- the Torblattunterkante 17 swings out of the Toröffsebenesebene outwards, which is why you could call the gate described here in principle as a swing gate.
- the rollers 16 engage the clip 5f.
- Fig. 1 the gate is shown ready to be transported from the manufacturer to the construction site and assembled for easy final assembly.
- the wire ropes 11 sit on the fall protection device 12 on.
- a first embodiment of the fall protection device 12 is in the Fig. 5 to 7 clarified in more detail.
- Fig. 5 shows the fall protection device 12 in a sectional side view
- Fig. 6 in cut rear view
- Fig. 7 shows the fall protection device 12 in plan view.
- the fall protection device 12 comprises an approximately U-shaped roller holder 20, on which the roller 16 is mounted by means of a bearing sleeve 21.
- This U-shaped roller holder 20 is attached to the corresponding side door leaf side edge 14 and has for this purpose corresponding screw openings 22.
- the rollers 16 are guided in the approximately J-shaped guide rails 5.
- the wire rope 11 is mounted.
- the second lever arm 25 acts with its free tapered engagement end 29 as a pawl 26.
- the second lever arm 25 is formed such that the engagement end 29 of the pawl 26 is disposed within the guide rail 5.
- Fig. 5 which shows the fall protection device 12 in the event of slack rope 11, the pointed engagement end 29 of the pawl 26 is angled towards one of the two parallel to the plane to be closed door opening profile leg 5b, 5c of the guide rail 5, so that the pointed engagement end 29 to this profile leg - on the present example of the C-profile legs 5c - extends, in which the engagement formations in the form of openings 13 are provided at regular intervals.
- the openings 13 have a greater extent in length and width than the engagement end 29 so that it can easily engage in the openings 13.
- the wire rope 11 is not attached centrally, but as far as possible away from the side, from which protrudes on the other lever arm 25, the engagement end 29.
- a spring 30 is provided, which the pawl lever 23 in the in Fig. 5 biased engagement shown biased.
- the tension of the spring 30 is chosen so that it is also in the in Fig. 2 shown opening position in which the roller holder 20 extends at an angle of about 90 ° to the longitudinal direction of the pawl lever 23, which yes the wire rope 11 attacks, still provides enough bias to trigger the pawl 26 in a slack wire rope 11.
- the in Fig. 1 shown closed position the pawl lever 23 and the roller holder 20 are almost parallel to each other. Due to the rotation, the bias of the spring 30 in this position is slightly higher; but it is still much less than the transmitted through the torsion spring 10 via the cable tension on the pawl lever 23 force that holds the pawl 26 in its release position.
- a second embodiment of the fall arrest device 12 is shown. This differs from the first embodiment substantially only by the shape of the pawl lever 23.
- the function and the other embodiment are substantially the same as those in the first embodiment, so that the above embodiments can be fully referenced.
- the pawl lever 23 can be easily prepared as sheet metal stampings.
- the engagement end 29 of the second embodiment is not tapered, as that of the first embodiment, but by a slightly angled tab 27 is formed.
- pawl member 31 has a pivotally mounted about the roller shaft 15 pawl holder 32 and a pawl 33 having pawl lever 37.
- the actual pawl 33 is thus not immediately pivotable about the roller axis 15 as at the first two embodiments, but only indirectly mounted on the pawl holder 32 on the roller axis 15.
- the pawl holder 32 comprises a concentrically arranged to the roller axis 15 sleeve 34 and a support member 36 mounted thereon, which in detail in Fig. 12 is shown.
- a receptacle 39 is provided for suspending the door leaf-side end of the wire rope 11, while the second lever arm with the free engagement end 29 forms the pawl 33.
- Fig. 13 it can be seen, in this embodiment, not the wire rope attack off-centered on the two-armed pawl lever 37, but the bearing 40 for the pawl axis 44.
- the pawl lever 37 thus pivots in a plane parallel to the door opening when slack of the wire rope 11, driven by the bias of a in Fig. 14 closer spring 41 shown.
- the fall protection device 12 moves the pawl lever 23 with each opening and closing operation relative to the door leaf 1.
- the spring 30 is opposite to the in Fig. 6 shown position by 180 ° pivoted pawl lever 23 unstressed and in the in Fig. 6 shown position stretched by 180 °.
- the pawl lever 23 moves according to the Torblattiolo in an angular range between about 180 ° and 90 °.
- the spring 30 is thus always biased in operation by at least 90 °. Due to the constant loading of the spring 30, it could come with prolonged use to a failure of the spring 30 by spring break. Such a spring break would essentially remain unnoticed and would have the fatal consequence of the failure of the fall protection device 12.
- torsion springs belong to the group of bending springs whose spring force is essentially due to bending and not achieved by twisting. However, bending can lead to spring breakage during long-term use.
- Fig. 15 shows an embodiment in which a fraction of the spring 30 serving for pawl bias is avoided or at least highly unlikely despite constant movement load during the gate operation.
- this is the spring 30 a - wound like a coil spring torsion biasing spring with a helical portion 102, where the individual spring coils 104 are wound at a distance such that the turns 104 in the entire Relativverschwenk Scheme of 0 - 180 ° of the door leaf Do not touch 1 to be fastened roller holder 20 and the pawl lever 23.
- the spring 30 further comprises a first spring leg 106 for detecting the pawl lever 23 and a second spring leg 108 for engagement with the roll holder 20.
- This sleeve element 110 serving as a spring guide element has a tubular or sleeve-shaped section 112 and a connection part, here in the form of a clothespin-shaped guide or detection section 114.
- the detecting portion 114 has a recess 116 into which the first spring leg 106 is inserted.
- the sleeve member 110 always moves together with the first spring leg 106 and, since this engages positively in an opening in the pawl lever 23, also always with the pawl lever 23.
- the detection portion 116 performs the first spring leg 106 on a circular motion to a to the sleeve-shaped portion 112 concentric axis. This prevents the first spring leg 106 from being bent relative to the coil portion 102 without twisting thereof. A Relativverschwenkung the pawl lever and the roller holder 20 therefore only leads to a rotation of the coil portion 102 and not to a deflection of the spring leg 106. In this way, the spring 30 is always loaded on rotation and not on bending.
- the helical region 102 never lies directly on a sleeve which moves relative to the first spring leg, for example the bearing sleeve 21, but at most on the sleeve-shaped section 112, which moves along with the first spring limb 106.
- the tubular or sleeve-shaped portion 112 extends only partially into the helical region 102, so that the windings 104 located near the second spring leg 108 may at least reduce the diameter of the helical region 102 relative to the roll holder 20 and thus relatively to the second spring leg 108 non-moving part, namely, for example, the bearing sleeve 21 rests, while windings 104 near the first spring leg 106 when reducing the diameter of the coil portion 102 at most rest on the sleeve-shaped portion 112.
- the helical portion 102, the bearing sleeve 21 and the tubular or sleeve-shaped portion 112 are dimensioned so that the spring 30 in an arrangement in which it reduces its diameter in the tensioned state, even at maximum tension (180 ° Relativermosung between pawl lever 23 and roller holder 20) does not rest on elements 110, 21 inserted in the helical region 102.
- the female member 110 may be made of any suitable material, preferably solid plastics.
- the torsion spring 10 of the weight balancing device 7 has, for example, an inner diameter of about 30 to 40 mm, preferably about 35 mm.
- the torsion spring shaft 8 is introduced.
- the torsion spring shaft 8 is mounted with its end portions 50 mounted on the frame 2 bearing elements 51.
- the bearing elements 51 are substantially U-shaped with a web 52 secured to the frame 2 and two respective bearings 54 for the end portion 50 having U-legs 53.
- the cable drum 9 is arranged between each of the two U-legs 53.
- the torsion spring shaft 8 is in the in Fig. 18 to 21 Embodiments of the invention shown as a hollow shaft tubular. This reduces an inclination of the torsion spring shaft 8 to bend under load of the uneven bias of the torsion spring 10 in the Torverlauf.
- the tubular torsion spring shaft 8 should, to have stability, have a diameter of more than 20 mm, preferably of about 25 mm or more.
- a drive or the like should be flanged to the equipped with tubular profile torsion spring shaft 8 at one of its end portions 50. This would normally be done via an annular flange and bolting. With a diameter of 25 mm, however, the ring flange already exceeds the dimensions of the frame (for example, the upper frame spar). For this reason, the tubular torsion spring shaft 8 is made thicker in its central portion 55 (e.g., approximately 25 mm in diameter) and tapered toward its end portions 50, for example, to a diameter of approximately 15 mm.
- the torsion spring shaft 8 is at its thinner portions, i. here the end sections 50, stored. As a result, there is significantly less bearing friction and less bearing resistance because of the smaller pipe diameter.
- the large pipe profile has a stability advantage. This is particularly advantageous for gates with drive. You have a stable tube profile in the middle and a dilute tube profile at the end.
- this is formed by a one-piece tube 56.
- the tube 56 has two smaller diameter end portions 50, the larger diameter middle portion 55, and a conical transition region 57.
- this tube 56 is done as follows: The tube 56 is pulled. Between the thin and the thick diameter, there is a conical transition zone in the transition region 57, the angle of the conical piece to the horizontal is approximately 15 to 20 °. The longitudinal extension of the conical transition amounts to, for example, 35-45 mm, preferably about 40 mm.
- FIGS. 20 and 21 Yet another embodiment of a usable as a torsion spring shaft 8 hollow shaft is shown. Also, it has the thicker middle portion 55 and the thinner end portions 50. However, the sections 55, 50 of different diameters are formed by individual tubes 58, 59. The end portions 50 forming thinner tubes 58 each have a spline 60 at one end. The middle section 55 forming thicker tube 59 is formed at its two ends with corresponding internal toothing, in which engage the splined ends of the thinner tubes 58 in the assembled state.
- the described embodiments of fall protection devices 12 and weight compensation devices 7 are also suitable for a similar as in Fig.
- FIG. 1 Another embodiment of a door is obtained by replacing the frame 2 shown in the drawings by a - if necessary already existing on-site or be prepared - wooden frame.
- the door leaf 1 is then analogous to that in the EP 0 513 773 A1 (see in particular the 4 to 6 and the accompanying text) shown and described Torblatt delivered with its fittings pre-assembled to the site. For more details will be in full on the EP 0 513 773 A1 directed.

Aufgabe der Erfindung ist es, ein Einblatt-Überkopf-Tor nach dem Oberbegriff des beigefügten unabhängigen Anspruches 1 bei auch längerem oder häufigen Betrieb sicherer und dennoch kostengünstiger zu gestalten.The object of the invention is to make a single-leaf overhead gate according to the preamble of the appended
Zum Lösen dieser Aufgabe ist ein Einblatt-Überkopf-Tor der im Oberbegriff des Anspruches 1 genannten Art durch die kennzeichnenden Merkmale des Anspruches 1 weitergebildet.To solve this problem, a single-sheet overhead gate referred to in the preamble of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Torsionsfederwelle muss für die hier beschriebene Anordnung besonders kompakt ausgebildet sein. Auch die eventuellen Torsionsfeder(n) darf bzw. dürfen keinen großen Durchmesser aufweisen. Bei den Toren der in Rede stehenden Art ist auch die Belastung der Torsionsfeder völlig anders als beispielsweise bei einem Sektionaltor. Bei den Toren der in Rede stehenden Art ist die auszugleichende Gewichtskraft des Tores nämlich während des ganzen Torverlaufs gleich. Aus diesem Grunde hat man bisher bei vielen vorher bekannten Toren dieser Art auch keine Torsionsfedern als Gewichtsausgleichseinrichtung, sondern Gegengewichte verwendet, da deren Kraft gleich bleibt, während sich die Federkraft von Gewichtsausgleichsfedern beim Torlauf ständig ändert. Entsprechend der kompakten Ausmaße muss die Torsionsfederanordnung der hier betrachteten Tore über einen langen Torsionsbereich, beispielsweise mehr als 20 Umdrehungen, wirksam sein: Z.B. wird die Torsionsfeder herstellerseitig um ca. 30 Umdrehungen vorgespannt. Die Torsionsfederbelastung ist also hier gerade am Anfang einer Öffnungsbewegung besonders hoch. Bei ersten Testen hat man zum Erreichen der kompakten Ausmaße ein Massivstab als Torsionsfederwelle eingesetzt. Aufgrund der Torsionsfederbelastung hat sich so eine Welle stark verbogen und eine Eierbewegung "wie eine Wurst" durchgeführt, was zu unruhigem Lauf, verkürzter Lebensdauer und unerwünschten Geräuschen geführt hat.The torsion spring shaft must be made particularly compact for the arrangement described here. The possible torsion spring (s) may or may not have a large diameter. At the gates of the type in question, the load on the torsion spring is completely different than, for example, a sectional door. In the gates of the type in question, the weight force of the goal to be equalized is the same throughout the entire course of the goal. For this reason, it has been used in many previously known gates of this type, no torsion springs as a counterbalancing device, but counterweights, since their force remains the same, while the spring force of counterbalance springs constantly changes during door travel. According to the compact dimensions, the torsion spring arrangement of the gates considered here must be effective over a long torsion range, for example more than 20 revolutions: e.g. the torsion spring is pretensioned by about 30 revolutions by the manufacturer. The Torsionsfederbelastung is therefore particularly high here just at the beginning of an opening movement. In the first tests, a solid rod was used as a torsion spring shaft to achieve the compact dimensions. Due to the torsion spring load, such a shaft has bent heavily and carried out an egg movement "like a sausage", which has led to restless running, shortened life and unwanted noise.
Die Torsionsfederwelle wird nun ganz als Hohlwelle ausgeführt. Die Torwelle ist also durch ein Rohr gebildet. Ein solches Rohr hat bei gleicher Masse einen größeren Außendurchmesser und ein größeres Widerstandsbiegemoment als eine Vollwelle. Dadurch ist die Durchbiegung - auch bei Anflanschen eines Antriebs an die Torwelle und dem sich ergebenden Eigengewicht - geringer. Eine geringere Durchbiegung verringert die Lagerbelastung und beugt somit einem sicherheitsrelevanten Ausfall der Gewichtsausgleichseinrichtung selbst bei längerem und häufigerem Betrieb ohne Wartung vor. Dennoch kann auf zusätzliche Stützlager verzichtet werden.The torsion spring shaft is now completely designed as a hollow shaft. The door shaft is thus formed by a tube. Such a tube has the same mass a larger outer diameter and a larger resistance bending moment than a solid shaft. As a result, the deflection - even with flanges of a drive to the door shaft and the resulting weight - less. A lower deflection reduces the bearing load and thus prevents a safety-relevant failure of the counterbalancing device even with prolonged and frequent operation without maintenance. Nevertheless, can be dispensed with additional support bearing.
Durch den Einsatz einer Hohlwelle als Torsionsfederwelle einer Torsionsfedereinrichtung wird eine für den Transport und die Montage außerordentlich vorteilhafte Ausbildung und Anordnung der Gewichtsausgleichseinheit innerhalb der von der Zarge überstrichenen Fläche ohne Nachteile in Bezug auf ruhigen Lauf und Lebensdauer ermöglicht.Through the use of a hollow shaft as a torsion spring shaft of a torsion spring means for the transport and assembly extremely advantageous design and arrangement of the weight compensation unit within the swept by the frame surface without disadvantages in terms of quiet running and life allows.
Bei anderen Arten von Toren mit Torsionsfederwellen treten die erwähnten spezifischen Probleme nicht auf. Beispielsweise ist die Torsionsfeder bei Sektionaltoren konisch vorgespannt. Ein Eiern in dem Maße wie bei den hier in Rede stehenden Kipptoren mit erfindungsgemäßer kompakter vormontierter Kraftquelleneinheit tritt dort nicht auf. Auch werden Sektionaltore in Einzelteilen und nicht in dem Maße vormontiert, wie die hier in Rede stehenden Einblatt-Überkopf-Tore geliefert.In other types of doors with torsion spring waves, the specific problems mentioned do not occur. For example, the torsion spring is biased at sectional doors conically. An eggs to the extent as in the here in question overhead doors with inventive compact preassembled power source unit does not occur there. Also sectional doors are pre-assembled in parts and not to the extent that delivered here in question single-leaf overhead doors.
Zur Stabilität des Torwelle wäre ein möglichst großer Rohrdurchmesser wünschenswert. Dem stehen aber die zur Verfügung stehenden begrenzten Ausmaße gegenüber, denn das Rohr muss in die Torsionsfeder eingreifen können und diese soll einen Durchmesser kleiner als die Höhe bzw. Breite des parallelen Zargenholmes haben. Insbesondere ist aber die Lagerung eines dicken Rohres problematisch, denn dies würde einerseits für die geforderte kompakte Anordnung zu große Lagerelemente, andererseits aber auch mit dem Durchmesser steigende Lagerreibungskräfte ergeben. Erfindungsgemäß ist vorgesehen, die mit einem Rohrprofil gebildete Torsionsfederwelle mit verschieden dicken Abschnitten zu versehen, nämlich dickeren Abschnitten, die die Welle gegen Verbiegen stabilisieren, und dünneren, an denen die Welle gelagert ist.For stability of the Torwelle the largest possible pipe diameter would be desirable. However, this is offset by the available limited dimensions, because the tube must be able to engage in the torsion spring and this should have a diameter smaller than the height or width of the parallel Zargenholmes. In particular, however, the storage of a thick pipe is problematic, because this would result on the one hand for the required compact arrangement too large bearing elements, on the other hand, but also with the diameter increasing bearing friction forces. According to the invention, to provide the Torsionsfederwelle formed with a tubular profile with different thickness sections, namely thicker sections that stabilize the shaft against bending, and thinner, where the shaft is mounted.
Vorteilhafterweise sind die Wellenenden gelagert und somit die Endabschnitte der ein Rohrprofil aufweisenden Torwelle dünner ausgeführt als deren sich zwischen den Lagerelementen erstreckender Mittelabschnitt. Die Ausbildung mit dünneren und dickeren Abschnitten ist auf verschiedene Arten möglich. Gemäß einer vorteilhaften Ausgestaltung ist die Torwelle einstückig ausgebildet mit konischen Übergangsbereichen zwischen den Abschnitten verschiedenen Durchmessers. In einer weiteren vorteilhaften Ausgestaltung ist die Torwelle aus Rohren verschiedenen Durchmessers zusammengefügt, wobei beispielsweise ein Ende eines dünneren Rohres in ein dickeres Rohr mittels einer (Keil-)Verzahnung drehfest in ein dickeres eingesetzt ist. Anstelle von Keilverzahnungen sind auch andere drehfeste Verbindungen (Schweißen, Splintverbindungen,...) für die Rohre unterschiedlichen Durchmessers denkbar.Advantageously, the shaft ends are mounted and thus the end portions of a tubular profile having a Torwelle made thinner than its extending between the bearing elements central portion. The training with thinner and thicker sections is possible in various ways. According to an advantageous embodiment, the door shaft is integrally formed with conical transition regions between the sections of different diameters. In a further advantageous embodiment, the door shaft is assembled from pipes of different diameters, wherein, for example, one end of a thinner pipe is inserted into a thicker pipe by means of a (wedge) toothing rotation in a thicker. Instead of splines other non-rotatable connections (welding, splint connections, ...) for the tubes of different diameters are conceivable.
Das Rohrprofil muss auch nicht über die gesamte Wellenlänge kreisrund sein, es könnten auch Stabilitätsgründen zumindest abschnittsweise auch andere Rohrprofilformen (quadratisch, sternförmig, mit Verstärkungsansätzen,...) zum Einsatz kommen.The tube profile also does not have to be circular over the entire wavelength, it could also stability reasons at least in sections, other tube profile shapes (square, star-shaped, with reinforcing approaches, ...) are used.
Die erfindungsgemäßen Vorteile lassen sich auch bei gattungsgemäßen (Canopy-)Toren erzielen, deren Torblätter und Gewichtsausgleichseinrichtungen zur Montage an einem Holzrahmen wie aus der
Bei einer ersten Ausführungsform der Erfindung wird vorgeschlagen, dass anstelle von Gegengewichten eine Torsionsfederwelle als Gewichtsausgleichseinrichtung verwendet wird. Dies spart Gewicht und damit Transportkosten; die Torsionsfederwelle kann bereits vorgespannt beim Hersteller vormontiert werden. Der Monteur braucht am Montageort das bereits in der Zarge vormontierte Tor nur auszurichten und die Zarge in dem Mauerwerk verankern, um ein betriebsfertiges Tor zu erhalten. Dabei wird trotz der nun in der Europäischen Union geltenden verschärften Sicherheitsbestimmungen auf die Sicherheit einer zweiten Torsionsfeder verzichtet, was ebenfalls Gewicht und Kosten spart. Dies ist bei dem Kipptor überraschenderweise ohne Sicherheitseinbußen möglich, weil die Absturzsicherungsvorrichtung ja nicht nur auf einen Seilbruch sondern auch auf einen Federbruch reagiert. Die Torsionsfederwelle selbst ist platzsparend an der Zarge befestigt. Dies lässt eine Vormontage der Torsionsfederwelle beim Hersteller zu, so dass Unsicherheiten durch fehlerhafte Montage und die Gefahr von Verletzungen des Montagepersonals, z.B. beim Spannen der Feder, verringerbar ist.In a first embodiment of the invention, it is proposed that instead of counterweights, a torsion spring shaft is used as weight compensation device. This saves weight and thus transport costs; The torsion spring shaft can already be pre-assembled preassembled at the manufacturer. At the installation site, the installer only needs to align the door, which is already preassembled in the frame, and anchor the frame in the masonry in order to obtain a ready-to-use gate. In spite of the tightened safety regulations now in force in the European Union, the safety of a second torsion spring is not required, which also saves weight and costs. This is surprisingly possible in the overhead door without loss of security, because the fall protection device not only reacts to a cable break but also to a spring break. The torsion spring shaft itself is space-saving attached to the frame. This allows a pre-assembly of the torsion spring shaft at the manufacturer, so that uncertainties due to incorrect installation and the risk of injury to the assembly personnel, e.g. when tensioning the spring, can be reduced.
Bei einer weiteren Ausführungsform der Erfindung wird vorgeschlagen, dass als Kraftquelle eine als Antriebswelle wirkende vormontierte Antriebseinheit mit Torwelle und Seiltrommeln verwendet wird. Diese Torwelle ist als Torsionsfederwelle der Torsionsfeder-Gewichtsausgleichseinrichtung ausgebildet. Dies spart Gewicht und damit Transportkosten; die Torsionsfederwelle kann bereits vorgespannt beim Hersteller vormontiert werden. Der Monteur braucht am Montageort das bereits in der Zarge vormontierte Tor nur auszurichten und die Zarge in dem Mauerwerk verankern, um ein betriebsfertiges Tor zu erhalten. Die Torwelle selbst ist platzsparend an der Zarge gelagert. Dies lässt eine Vormontage der Torwelle beim Hersteller zu, so dass Unsicherheiten durch fehlerhafte Montage und die Gefahr von Verletzungen des Montagepersonals, z.B. beim Spannen der Feder bei als Torsionsfederwelle ausgebildeter Torwelle, verringerbar ist. Die Antriebseinheit bestehend aus Torsionsfederwelle und wenigstens einer Zugmitteltrommel, ist in ihrer in Höhen- und Breitenrichtung derart bemessen, dass sie weder zur Seite hin noch nach oben oder in die durch die Zarge umrahmte Toröffnung hin in Richtung parallel zur Zargenebene gesehen über die Zarge vorsteht. Sie ragt lediglich in Dickenrichtung in den zu verschließenden Raum hinein, nutzt aber ansonsten den auch für die Zarge benötigten Raum. Auf diese Weise kann das voll vormontierte Tor platzsparend transportiert und ohne Schwierigkeiten und ohne die Notwendigkeit eines nachträglichen Einbaus und den damit verbundenen Sicherheitsriskiken durch Fehlmontage an der Baustelle in die zu verschließende Mauerwerksöffnung eingepasst werden.In a further embodiment of the invention, it is proposed that a preassembled drive unit acting as a drive shaft with a door shaft and cable drums be used as the power source. This Torwelle is designed as a torsion spring shaft of the torsion spring counterbalancing device. This saves weight and thus transport costs; The torsion spring shaft can already be pre-assembled preassembled at the manufacturer. At the installation site, the installer only needs to align the door, which is already preassembled in the frame, and anchor the frame in the masonry in order to obtain a ready-to-use gate. The door shaft itself is stored space-saving on the frame. This allows a pre-assembly of the door shaft at the manufacturer, so that uncertainties due to incorrect installation and the risk of injury to the assembly personnel, eg when tensioning the spring when designed as a torsion spring shaft Torwelle, can be reduced. The drive unit consisting of torsion spring shaft and at least one traction mechanism drum is dimensioned in height and width direction such that it protrudes beyond the frame neither toward the side nor upwards or into the door opening framed by the frame in the direction parallel to the frame plane. It protrudes only in the thickness direction in the space to be closed, but otherwise uses the space also required for the frame. To this Way, the fully preassembled door can be transported to save space and fitted without difficulty and without the need for subsequent installation and the associated safety risks by incorrect assembly at the site in the masonry opening to be closed.
Gemäß noch einer Ausführungsform der Erfindung bei der sich ein Sperrklinkenhebel beim Betrieb des Tores relativ zu dem Torblatt verschwenkt, ist eine Vorspannfeder zum Vorspannen des Sperrklinkenhebels in die Erfassungsstellung unter Belastung beim Torbetrieb stets in Bewegung. Zur Vermeidung eines dadurch bedingten Federbruchs der Vorspannfeder ist vorgesehen, dass diese Feder im gesamten Verschwenkbereich zwischen dem Sperrklinkenhebel und Torblatt ausschließlich auf Verdrehung eines an der Feder ausgebildeten Wendelbereiches beansprucht ist. Belastungen durch ständige bereichsweise Verbiegung einer Feder werden somit vermieden. Die Federbelastung wird wie bei einer auf zugbelasteten Schraubenfeder auf mehrere Windungen eines Wendelbereiches verteilt, die sich untereinander verdrehen.According to another embodiment of the invention in which a pawl lever pivots relative to the door leaf during operation of the door, a biasing spring for biasing the pawl lever in the detection position under load during door operation is always in motion. To avoid a consequent spring breakage of the biasing spring is provided that this spring is claimed in the entire pivoting between the pawl lever and door leaf exclusively on rotation of a spring formed on the coil portion. Loads by constant regional bending of a spring are thus avoided. The spring load is distributed over a plurality of turns of a helical region, which rotate with each other as in a tensioned on a helical spring.
Eine solche Federausbildung und -anordnung hat eine besonders hohe Lebensdauer, so dass Gefahren durch Federbruch vermieden oder zumindest so weit wie möglich eingedämmt sind.Such a spring design and arrangement has a particularly long life, so that risks are avoided by spring breakage or at least as far as possible contained.
Eine weitere - wenn auch weniger bevorzugte - Ausgestaltung sieht gemäß vor, den Sperrklinkenhebel nicht direkt an dem Torblatt zu lagern, sondern an einem sich gegenüber dem Torblatt verschwenkenden Sperrklinkenhalter. Auf diese Weise wird die Vorspannfeder bei der Torbewegung nicht bewegt, da die Vorspannfeder nur zwischen dem Sperrklinkenhalter und dem Sperrklinkenhebel wirksam sein muss. Die Kipp- oder Verschwenkbewegung des Torblattes bewirkt eine Verschwenkung des Sperrklinkenhalters relativ zu dem Torblatt.Another - albeit less preferred - embodiment according to, not to store the pawl lever directly to the door leaf, but on a pivoting relative to the door leaf pawl holder. In this way, the biasing spring is not moved in the door movement, since the biasing spring must be effective only between the pawl holder and the pawl lever. The tilting or pivoting movement of the door leaf causes a pivoting of the pawl holder relative to the door leaf.
Die gemäß einer vorteilhaften Weiterbildung der Erfindung vorgesehene Anlenkung von Rollen oder dergleichen in einer der Zarge zugeordneten vertikalen Führungsschiene geführten Torblattführungselementen nicht an der unteren Torblattkante, sondern näher zu einer Hebelanlenkung eines zum Führen der oberen Torblatthälfte vorhandenen Hebelwerks und/oder zur vertikalen Torblattmitte hin versetzt hat gleich mehrere Vorteile: Zum einen sind ein vertikaler Führungsbereich an der Zarge und damit die Führungsschienen und eventuelle Gegenlager für die Absturzsicherung kürzer als bei weiter zur unteren Torblattkante hin versetzten Führungsrollen. Zum anderen ist der Torbewegungsbereich von dem Garageninneren weiter nach außen versetzt - die untere Torblattkante schwenkt im Zuge der Öffnungsbewegung nach außen hin aus -, so dass im Inneren des zu verschließenden Raumes mehr Platz beispielsweise für parkende Autos zur Verfügung steht.The provided according to an advantageous embodiment of the invention articulation of rollers or the like in one of the frame associated vertical guide rail Guided Torblattführungselementen not on the lower door leaf edge, but has moved closer to a Hebelanlenkung existing for guiding the upper half of the door leaf lever system and / or the vertical Torblattmitte out several advantages: Firstly, a vertical guide area on the frame and thus the guide rails and any counter-bearing for fall protection are shorter than in further to the lower edge of the door leaf offset guide rollers. On the other hand, the Torbewegungsbereich of the interior of the garage further outwardly offset - the lower door leaf edge pivots outwardly in the course of the opening movement - so that more space is available, for example for parked cars in the interior of the space to be closed.
Vorteilhafterweise greift an beiden Torblattseiten jeweils eine von zwei Seileinheiten der das Torblatt mit der Torsionsfederwelle verbindenden Seilzuges an, welche Seileinheiten jeweils durch ein Seil oder mehrere parallele Seile gebildet sind. Mit dem anderen Ende werden die Seileinheiten jeweils auf an den Enden der Torsionsfederwelle vorgesehene Seiltrommeln oder dergleichen Wickeleinrichtung aufgewickelt.Advantageously, attacks on both Torblattseiten one of two cable units of the door leaf with the Torsionsfederwelle connecting cable to which cable units are each formed by a rope or more parallel cables. At the other end, the cable units are each wound on provided at the ends of the torsion spring shaft cable drums or the like winding device.
Die Befestigung von Lagerelementen der Torsionsfederwelle erfolgt z.B. unmittelbar am oberen Zargenholm. Die Dimensionen der Torsionsfederwelle, d.h. insbesondere deren Außendurchmesser (ggfs. auch der der Seiltrommeln) ist weiter bevorzugt derart, dass sie nicht über die Zargenholme hinausragt und zwar weder nach außen noch nach innen zur Toröffnung hin. Diese kompakte Bauart ermöglicht eine vollständige Vormontage der Gewichtsausgleichseinrichtung des erfindungsgemäßen Torblattes beim Hersteller, ohne dass die Gewichtsausgleichseinrichtung bei der Montage stört.The attachment of bearing elements of the torsion spring shaft is e.g. directly on the upper frame spar. The dimensions of the torsion spring shaft, i. in particular its outer diameter (if necessary. Also that of the cable drums) is more preferably such that it does not protrude beyond the Zargenholme and that neither outwardly nor inwardly toward the door opening. This compact design allows complete pre-assembly of the weight balancing device of the door panel according to the invention by the manufacturer, without the weight balancing device interfering with the assembly.
Absturzsicherungen sind bisher hauptsächlich für sich zumindest teilweise im wesentlichen rein vertikal bewegende Torblätter vorgeschlagen worden, also beispielsweise solche von Deckengliedertoren, deren untere Paneele den Großteil ihrer Bewegung in vertikalen Führungsschienen geführt zurücklegen, oder von Hubtoren, welche im ganzen nach oben geführt werden. Bekannte Absturzsicherungen umfassen am entsprechenden seitlichen Torblattbereich fest gelagerte Gehäuse, in denen eine Sperrklinke schwenkbar gelagert ist, welche bei Schlaffwerden des Seiles ausgelöst wird - dies meist über Freigabeelemente, welche sich bei Schlaffwerden des Seiles aus dem Bewegungsbereich der Sperrklinke bewegen. Solche bekannten Absturzsicherungen sind einerseits kompliziert im Aufbau und andererseits nicht auf die hier interessierenden Kipp- oder Schwenktore übertragbar, da ja diese Kipp- oder Schwenktore neben einer vertikalen Bewegung auch eine Kippbewegung durchführen, diese Art von Absturzsicherungen aber einen Torblattbereich zum Anordnen der Sperrklinke erfordern, dessen Ausrichtung während des zu sichernden Torblattbewegungsablaufes konstant bleibt.Fall protection devices have hitherto been proposed, at least in part, essentially purely vertically moving door leaves, that is to say, for example, those of ceiling sectional doors, the lower panels of which carry the majority of their movement in vertical guide rails, or of lifting gates, which are guided upwards in their entirety. Known fall protection devices comprise housings which are fixedly mounted on the corresponding side door leaf area and in which a pawl is pivotally mounted, which is triggered when the rope slackens - usually via release elements which move out of the range of movement of the pawl when the cable is slack. On the one hand, such known fall arresters are complicated to construct and, on the other hand, can not be transferred to the tilting or swiveling gates of interest here since these tilting or swiveling gates also perform a tilting movement in addition to a vertical movement, but require a door leaf area for arranging the pawl. whose orientation remains constant during the Torblattbewegungsablauf to be secured.
Die hier beschriebenen Absturzsicherungen weisen dagegen vorteilhafterweise ein an oder parallel zur Rollenachse um die Rollenachse schwenkbar gelagertes Sperrklinkenelement auf, das bei Verkippen des Torblattes relativ zum Torblatt schwenken kann und dadurch seine Lage relativ zu einer ortsfesten Eingriffsausbildung, welche im Auslösefall von der Sperrklinke erfasst wird, beibehält. Die Absturzsicherungsvorrichtung lässt sich weiterhin besonders einfach dadurch ausbilden, dass sie eine an einem Sperrklinkenhebel ausgebildete Sperrklinke umfasst, die in Sperr- oder Eingriffslage federbelastet vorgespannt ist und die durch die Seilzugspannung entgegen dieser Vorspannung in ihre Freigabestellung gezogen ist. Dies lässt sich besonders einfach dadurch realisieren, dass das torblattseitige Ende jeder Seileinheit nicht am Torblatt selber angreift, sondern an dem Sperrklinkenhebel und die Seilzugkräfte über den Sperrklinkenhebel, die Sperrklinke in die Freigabestellung ziehend, auf das Torblatt überträgt.By contrast, the fall arresters described here advantageously have a pawl element which is pivotably mounted on or parallel to the roll axis about the roll axis and which can pivot relative to the door leaf when the door leaf is tilted and thereby retains its position relative to a stationary engagement formation, which is detected by the pawl in the event of triggering. The fall protection device can also be particularly simple in that it comprises a formed on a pawl lever pawl which is biased spring-loaded in the locking or engagement position and which is pulled by the cable tension against this bias to its release position. This can be realized particularly easily by the fact that the door leaf-side end of each cable unit does not attack the door leaf itself, but transmits to the pawl lever and the cable pulling forces on the pawl lever, the pawl pulling into the release position on the door leaf.
In einer bevorzugten Ausführungsform ist das Sperrklinkenelement selbst als Sperrklinkenhebel ausgebildet. Dieser kann wiederum durch einen wenigstens zweiarmigen Hebel gebildet sein, wobei ein Hebelarm als Sperrklinke ausgebildet ist und einen die Eingriffsausbildung in der Sperrstellung erfassenden Eingriffsbereich aufweist und der zweite Hebelarm einen Angriff für die Seilzugeinrichtung aufweist. Es ist zwar auch eine einarmige Ausbildung denkbar, beispielsweise dadurch, dass die Seilzugspannung die Sperrklinke im Normalbetrieb gegen einen Anschlag zieht. Dieser sollte dann aber zur Vermeidung eines komplizierten Aufbaus auch auf dem schwenkbaren Sperrklinkenelement ausgebildet sein. Bei der zweiarmigen Lösung kommt man ohne Anschlag und mit kurzen Eingriffswegen aus. Besonders einfach ist die Ausbildung, wenn ein solcher Sperrklinkenhebel direkt an der Rollenachse der einzelnen seitlichen Führungsrolle an jeder Seite schwenkbar gelagert ist.In a preferred embodiment, the pawl element itself is designed as a pawl lever. This can in turn be formed by an at least two-armed lever, wherein a lever arm is designed as a pawl and has a engagement formation in the blocking position engaging engagement portion and the second lever arm has an attack on the cable pulling device. Although it is also a one-armed training conceivable, for example, characterized in that the cable tension pulls the pawl in normal operation against a stop. This should then be designed to avoid a complicated structure on the pivotable pawl element. In the two-armed solution to get out without a stop and with short engagement paths. Particularly simple is the training, when such a pawl lever is pivotally mounted directly on the roller axis of the individual lateral guide roller on each side.
Das Sperrklinkenelement kann dann durch nur ein einzelnes bewegliches Teil, nämlich den Sperrklinkenhebel gebildet sein.The pawl member may then be formed by only a single movable part, namely the pawl lever.
Die Rollenachse ist im allgemeinen parallel zur Torblattebene und legt vorzugsweise auch die Kippachse für das Tor fest. Aufgrund der Lagerung des Sperrklinkenhebels eben an dieser Achse lässt sich dieser in seiner Freigabestellung beispielsweise in vertikaler oder leicht schräg zur Vertikalen liegender Freigabestellung während der gesamten Torblattbewegung halten. Wird das Seil schlaff, so bewegt sich der Sperrklinkenhebel durch die Federvorbelastung in die Sperrstellung und greift dann in die Eingriffsausbildung ein, so dass das Torblatt auch im Auslösefall weiterhin an seiner Rollenachse gehalten wird.The roller axle is generally parallel to the door leaf plane and preferably also defines the tilting axis for the door. Due to the mounting of the pawl lever just on this axis can be this hold in its release position, for example, in vertical or slightly inclined to the vertical release position during the entire Torblattbewegung. If the rope becomes limp, then the pawl lever moves through the spring preload in the blocking position and then engages in the engagement training, so that the door leaf is still held on its roller axis in the event of triggering.
Die Eingriffsausbildung lässt sich besonders vorteilhaft und einfach direkt an oder in der Führungsschiene für die Rollen ausbilden. Bei der eben geschilderten Ausführungsform mit an der Rollenachse schwenkbar gelagertem Sperrklinkenhebel kann beispielsweise ein etwa zur Toröffnungsebene paralleler, eine Bahn für eine Rolle bildender Bereich der Führungsschiene mit der Eingriffsausbildung versehen sein. In besonders einfacher Ausgestaltung ist einfach auf dem gesamten Verlauf der Führungsschiene an diesem zur Toröffnungsebene parallelen Bereich eine Reihe von Öffnungen vorgesehen, wobei das Eingriffsende der Sperrklinke entsprechend mit einem spitzen Winkel endend so ausgebildet ist, dass dieses Ende bei durch Schlaffwerden des Seiles freigegebener Sperrklinke in die in Fallrichtung gesehen nächste Öffnung eingeführt wird und dort das Torblatt gegen Absturz sichert.The engagement training can be particularly advantageous and easy train directly on or in the guide rail for the rollers. In the just described embodiment with the pawl lever pivotally mounted on the roller axle, for example, a region of the guide rail which is parallel to the door opening plane and forms a path for a roller can be provided with the engagement formation. In a particularly simple embodiment, a series of openings is simply provided on the entire course of the guide rail parallel to the gate opening plane area, wherein the engagement end of the pawl is designed correspondingly terminated with an acute angle so that this end in released by slackening of the rope pawl in the next opening as seen in the direction of fall is introduced and secures the door leaf against falling there.
An dem zweiten Hebelarm ist ein Seilangriff vorzugsweise nicht mittig vorgesehen, sondern außermittig, an der der Eingriffsausbildung in bestimmungsgemäßem Gebrauch angewandten Längshälfte des zweiarmigen Hebels, welcher die Sperrklinke bildet. Diese außermittige Anordnung sorgt bei straffem Seil für die Aufbringung eines Drehmomentes auf die Sperrklinke, und zwar entgegen der Vorspannung. Der außermittigen Anordnung äquivalent wäre eine entsprechende Abwinklung der Hebelarme zueinander oder eine entsprechende Versetzung der Hebelachse am Sperrklinkenhebelkörper. Die außermittige Anordnung ist der einfacheren Fertigung wegen und aus Platzgründen derzeit bevorzugt.At the second lever arm, a cable attack is preferably not centrally provided, but off-center, at the engagement training in normal use applied longitudinal half of the two-armed lever, which forms the pawl. This eccentric arrangement ensures a tight rope for the application of torque to the pawl, against the bias. The eccentric arrangement would be equivalent to a corresponding bending of the lever arms to each other or a corresponding displacement of the lever axis on the pawl lever body. The eccentric arrangement is the simpler manufacturing because of space reasons and currently preferred.
Die Vorspannung selbst ist derart gewählt, dass sie im gesamten Verschwenk- oder Kippwinkelbereich des Torblattes genügend Spannung zum Auslösen der Sperrklinke bereit stellt, aber dennoch niemals so groß wird, dass sie nicht durch die Seilzugspannung überwunden werden kann. Im oberen Bereich kann auch ein Abdeckelement vorgesehen sein, um die oberste Öffnung oder die obersten Öffnungen gegen Eingriff der Sperrklinke abzudecken. So bleibt das Tor auch bei einem geringfügigen Nachlassen der Torsionsfederspannung oder schlechterer Abstimmung funktionsfähig, wobei dennoch die Herstellung der Führungsschiene als Stück eines Endlosprofils mit einer durchgängigen Reihe von Öffnungen industriell vorteilhaft möglich ist. Andererseits können insbesondere aufgrund des Abdeckelements die Führungsschienen links und rechts identisch ausgebildet und damit einfacher industriell herstellbar sein. Links werden sie dann gegenüber der rechten Anordnung auf dem Kopf gestellt an der Zarge angebracht, bspw. geschweißt. Die jeweils oberste Öffnung, die auf der jeweils anderen Seite als unterste Öffnung notwendig ist, kann dann durch ein Eingriffteil gegen Eingriff durch die Sperrklinke gesichert sein. Anstelle oder zusätzlich zu einer Abdeckfunktion könnte ein solches Eingriffsteil, das beispielsweise durch eine aufklipsbare Klammer gebildet sein kann, auch derart ausgebildet sein, dass es als eine Art Raste für die Rolle zum Halten des Torblattes in der obersten Stellung und zum Vorsehen einer für die Bedienperson spürbaren die Öffnungsstellung markierenden Rastschwelle wirkt.The bias itself is chosen so that it provides sufficient voltage to trigger the pawl throughout the pivoting or tilt angle range of the door leaf, but never becomes so large that it can not be overcome by the cable tension. In the upper area may also be provided a cover to cover the uppermost opening or the uppermost openings against engagement of the pawl. Thus, the gate remains functional even with a slight decrease in the torsional spring tension or worse tuning, yet the manufacture of the guide rail as a piece of an endless profile with a continuous series of openings is industrially advantageous possible. On the other hand, in particular due to the cover, the guide rails left and right identically designed and thus easier to manufacture industrially. Left they are then placed opposite the right arrangement on the head attached to the frame, for example. Welded. The respective uppermost opening, which is necessary on the other side as the lowest opening, can then be secured by an engagement member against engagement by the pawl. Instead of or in addition to a covering function, such an engaging part, which may be formed, for example, by a clip-on clamp, could also be designed such that it acts as a kind of catch for the roller for holding the door leaf in the uppermost position and for providing a noticeable for the operator the opening position marking detent threshold acts.
Bei der alternativen Lösung ist die Sperrklinke oder ein diese aufweisender Sperrklinkenhebel nicht direkt an der Rollenachse gelagert, sondern indirekt über einen Klinkenhalter, welcher vorzugsweise wiederum selbst schwenkbar an der Rollenachse gelagert ist. Der Klinkenhalter kann somit immer die gleiche Lage zur Eingriffsausbildung während des gesamten Bewegungsablaufes des Torblattes beibehalten. An dem Klinkenhalter kann dann der entsprechend wie oben beschrieben ausgebildeter Sperrklinkenhebel oder auch eine sonstige Sperreinrichtung in beliebiger Ausgestaltung vorgesehen werden. Es wäre beispielsweise auch möglich, an einem solchen Klinkenhalter einen bei Schlaffwerden des Seiles auslösenden Bolzen vorzusehen, der in ortsfeste Widerlager einrastet. Vorteilhafterweise ist aber auch hier die in Sperrstellung vorbelastete Sperrklinke vorgesehen, die durch die Seilzugspannung entgegen dieser Vorbelastung in ihre Freigabestellung gezogen wird. Eine solche Ausbildung kommt ohne zusätzliche Elemente wie sich erst bei Schlaffwerden aus der Bahn des Sperrbolzens oder Sperrklinke oder dergleichen wegzuführende Auslöseelemente aus. Vorteilhafterweise ist auch hierbei die Sperrklinke an einem zweiarmigen Sperrklinkenhebel ausgebildet, wobei der erste Hebelarm die Sperrklinke bildet und beispielsweise ebenfalls mit einem spitz zulaufenden Eingriffsende versehen ist und an dem anderen Hebelarm ein Angriff für das torblattseitige Ende der entsprechenden Seilzugeinheit vorgesehen ist. Aufgrund des Klinkenhalters, an dem diese Sperrklinke schwenkbar gelagert ist, lässt sich ein Verschwenken der Sperrklinke beispielsweise auch senkrecht zur Rollenachse ausbilden. In einem solchen Fall sind die Eingriffsausbildungen an einem sich senkrecht zur Toröffnung erstreckenden Bereich der Führungsschiene ausbildbar. Vorteilhafterweise sind auch hier einfach nur Öffnungen vorgesehen, in welcher das spitze Eingriffsende der Sperrklinke eingreift.In the alternative solution, the pawl or a pawl lever exhibiting these is not mounted directly on the roller axis, but indirectly via a pawl holder, which in turn is preferably itself pivotally mounted on the roller axis. The pawl holder can thus always maintain the same position for engaging training throughout the movement sequence of the door leaf. At the pawl holder can then be provided in accordance with any design as appropriate described above pawl lever or other locking device. It would also be possible, for example, to provide on such a pawl holder a triggering of the rope causing bolt, which engages in stationary abutment. Advantageously, but also in the blocking position preloaded pawl is provided, which is pulled by the cable tension against this preload in its release position. Such a design comes without additional elements such as only when slack from the path of the locking pin or pawl or the like wegzuführende triggering elements. Advantageously, in this case, the pawl is formed on a two-armed pawl lever, wherein the first lever arm forms the pawl and, for example, also provided with a tapered engagement end and on the other lever arm an attack for the door leaf end of the corresponding Seilzugeinheit is provided. Due to the pawl holder on which this pawl is pivotally mounted, a pivoting of the pawl, for example, also form perpendicular to the roll axis. In such a case, the engagement formations can be formed on a region of the guide rail extending perpendicularly to the door opening. Advantageously, just here openings are also provided in which engages the pointed engagement end of the pawl.

Die Absturzsicherungsvorrichtung 12 umfasst einen in etwa U-profilförmigen Rollenhalter 20, an welchem die Rolle 16 mittels einer Lagerhülse 21 gelagert ist. Dieser U-profilförmige Rollenhalter 20 wird an dem entsprechenden seitlichen Torblattseitenrand 14 befestigt und weist hierzu entsprechende Schraubenöffnungen 22 auf. Die Rollen 16 sind in dem etwa J-profilförmigen Führungsschienen 5 geführt. Ebenfalls auf der Lagerhülse 21 gelagert, und zwar schwenkbar um die Rollenachse 15, ist ein Sperrklinkenelement, welches hier als zweiarmiger Sperrklinkenhebel 23 ausgebildet ist. An einem ersten Hebelarm 24 ist das Drahtseil 11 eingehängt. Der zweite Hebelarm 25 wirkt mit seinem freien spitz zulaufenden Eingriffsende 29 als Sperrklinke 26. Wie aus
An dem ersten Hebelarm 24 ist das Drahtseil 11 nicht mittig angehängt, sondern soweit wie möglich entfernt von der Seite hin, von der an dem anderen Hebelarm 25 das Eingriffsende 29 abragt. Außerdem ist eine Feder 30 vorgesehen, welche den Sperrklinkenhebel 23 in die in

Bei ersten Prototypen hat man für die Feder 30 bei Sperrklinken übliche eng - d. h. auf Berührung ihrer Windungen - gewickelte Schenkelfedern verwendet. Solche Schenkelfedern gehören zur Gruppe der Biegefedern, deren Federkraft im wesentlichen durch Verbiegen und nicht durch eine Verdrehung erreicht wird. Verbiegungen können aber bei dauerhaftem Einsatz zu Federbrüchen führen.In the first prototypes have been used for the

Auf diese Weise bewegt sich das Buchsenelement 110 stets zusammen mit dem ersten Federschenkel 106 und, da dieser in einer Öffnung in dem Sperrklinkenhebel 23 formschlüssig eingreift, auch stets mit dem Sperrklinkenhebel 23. Der Erfassungsabschnitt 116 führt dabei den ersten Federschenkel 106 auf einer Kreisbewegung um eine zu dem hülsenförmigen Abschnitt 112 konzentrischen Achse. Dies verhindert, dass der erste Federschenkel 106 gegenüber dem Wendelbereich 102 ohne Verdrehung desselben verbogen werden kann. Eine Relativverschwenkung des Sperrklinkenhebels und des Rollenhalters 20 führt daher nur zu einer Verdrehung des Wendelbereichs 102 und nicht zu einer Verbiegung des Federschenkels 106. Auf diese Weise wird die Feder 30 stets auf Verdrehung und nicht auf Verbiegung belastet. Dabei liegt der Wendelbereich 102 niemals direkt auf einer sich gegenüber dem ersten Federschenkel bewegenden Hülse wie beispielsweise der Lagerhülse 21, sondern allenfalls auf dem hülsenförmigen Abschnitt 112 auf, der sich mit dem ersten Federschenkel 106 mitbewegt.In this way, the sleeve member 110 always moves together with the
In nicht dargestellten Ausführungsformen reicht der rohr- oder hülsenförmige Abschnitt 112 nur teilweise in den Wendelbereich 102 hinein, so dass die nahe dem zweiten Federschenkel 108 liegenden Windungen 104 bei Verringerung des Durchmessers des Wendelbereichs 102 allenfalls auf einem sich relativ zu dem Rollenhalter 20 und damit relativ zu dem zweiten Federschenkel 108 nicht bewegenden Teil, nämlich beispielsweise der Lagerhülse 21 aufliegt, während Windungen 104 nahe des ersten Federschenkels 106 bei Verringerung des Durchmessers des Wendelbereiches 102 allenfalls auf dem hülsenförmigen Abschnitt 112 aufliegen.In non-illustrated embodiments, the tubular or sleeve-shaped portion 112 extends only partially into the
Der Wendelbereich 102, die Lagerhülse 21 und der rohr- oder hülsenförmige Abschnitt 112 sind jedoch so bemessen, dass die Feder 30 in einer Anordnung, in der sie im gespannten Zustand ihren Durchmesser verringert, auch bei Maximalspannung (180° Relativerdrehung zwischen Sperrklinkenhebel 23 und Rollenhalter 20) nicht auf in den Wendelbereich 102 eingeführten Elementen 110, 21 aufliegt.However, the

Die Torsionsfeder 10 der Gewichtsausgleichseinrichtung 7 hat beispielsweise einen Innendurchmesser von etwa 30 bis 40 mm, vorzugsweise etwa 35 mm. Darin ist die Torsionsfederwelle 8 eingeführt. Die Torsionsfederwelle 8 ist mit ihren Endabschnitten 50 in an der Zarge 2 befestigten Lagerelementen 51 gelagert. Die Lagerelemente 51 sind im wesentlichen U-förmig mit einem an der Zarge 2 befestigten Steg 52 und zwei jeweils ein Lager 54 für den Endabschnitt 50 aufweisenden U-Schenkeln 53. Die Seiltrommel 9 ist jeweils zwischen den beiden U-Schenkeln 53 angeordnet.The

Die rohrförmige Torsionsfederwelle 8 soll, um Stabilität zu haben, einen Durchmesser von mehr als 20 mm, vorzugsweise von ca. 25 mm oder mehr, haben. Andererseits soll an die mit Rohrprofil ausgestattete Torsionsfederwelle 8 an einem ihrer Endabschnitte 50 ein Antrieb oder dergleichen angeflanscht werden können. Dies würde normalerweise über einen Ringflansch und Verschrauben geschehen. Bei einem Durchmesser von 25 mm kommt man mit dem Ringflansch aber bereits über die Ausmaße der Zarge (z.B. des oberen Zargenholmes) hinaus. Aus diesem Grunde ist die rohrförmige Torsionsfederwelle 8 in ihrem mittleren Abschnitt 55 dicker (z.B. ca. Durchmesser 25 mm) und hin zu ihren Endabschnitten 50 verjüngt ausgeführt, beispielsweise auf einen Durchmesser von ca. 15 mm. Die Torsionsfederwelle 8 ist an ihren dünneren Abschnitten, d.h. hier den Endabschnitten 50, gelagert. Dadurch gibt es bedeutend weniger Lagerreibung und weniger Lagerwiderstand wegen des geringeren Rohrdurchmessers. Andererseits hat das große Rohrprofil einen Stabilitätsvorteil. Dies ist besonders vorteilhaft für Tore mit Antrieb. Man hat ein stabiles Rohrprofil in der Mitte und ein verdünntes Rohrprofil am Ende.The tubular

Die Herstellung dieses Rohres 56 geschieht folgendermaßen: Das Rohr 56 wird gezogen. Zwischen dem dünnen und dem dicken Durchmesser gibt es im Übergangsbereich 57 eine konische Übergangsstrecke, der Winkel des konischen Stücks zur Waagerechten beträgt ca. 15 bis 20°. Die Längserstreckung des konischen Überganges beläuft sich auf beispielsweise 35 - 45 mm, vorzugsweise ca. 40 mm.The production of this
