Description

The invention relates to a single-leaf overhead tilt gate having the features of the preamble of claim 1, as in the alternative to a) from the FR 1 424 037 is known. This document will be discussed in more detail below.

The FR 15 21 631 and the DE 16 92 017 U describe a tilting gate with a rigid door leaf whose upper portion 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. By this mechanism, the lower door leaf edge swings in the opening process out of the closing level and protrudes in the horizontal opening position of the door leaf forming a kind of canopy forming out of the garage opening. An advantage of this type of door is the small footprint inside the garage. Also, no horizontal guide rails or the like must be mounted in the garage interior. The known gates of the generic type are provided with a power source with counterweights for Torlaubgewichtsausgleich whose trajectory along the vertical Zargenholme runs and each with cables whose free ends in the Torblattführungselemente attack on the door panel provided.

The DE 92 02 302 U1 describes a tilting 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 the door leaf in the course of movement tilts between its horizontal opening position and its vertical closed position as a whole. As a power source for the weight balance also acting on a cable counterweight device is provided.

From the EP 0 156 415 A1 and the DE 37 10 237 A1 are sectional doors; ie gates whose door leaves from each hinged to each other via hinged hinged panels known. The known sectional doors have as weight balancing on a mounted above the door opening massive Torsionsfederwelle with two torsion springs.

From the US 3 412 423 a weight balancing device for a kind of sectional door at the rear of a truck is known. The weight balancing device has two tube shafts, which are each stored several times and are coupled to each other in the middle. At the end of each tube shaft, a cable drum with a rope is provided in each case.

The US 5 036 899 relates to an opening mechanism for a sectional door, wherein on the uppermost panel, a moving motor is mounted, whose force is passed via mounted on the panel hollow shafts at the end of the shaft rotatably mounted gears: The gears engage with rack sections in the guide rails. This type of drive mechanism is intended to allow a particularly easy installation of the sectional door with drive the sectional door with drive. It is also envisaged to provide torsion springs on the drivingly mounted on the panel drive shaft, which should support the drive when lifting the gate. The traveling on the door leaf units contribute to increasing the Torblattgewichtes so that the torsion springs can support the drive only slightly and are not sufficient for a balance of weight.

Those from the above mentioned FR 15 21 631 . DE 16 92 017 U and DE 92 02 302 U1 Known tilt gates are characterized in contrast to the sectional doors formed by several door leaf members by simpler manufacture and assembly and thus usually also by their cheaper price. In particular, these types of gates can already be pre-assembled to a high degree at the place of manufacture and transported in the pre-assembled state to the installation site.

From the FR 2 423 612 A1 is known a tilt gate with drive. The drive is attached to a particularly wide Zargenholm. He drives a Torwelle via an endless chain, which in turn carries chain sprockets at their ends.

A Another chain is on guided on vertical slides brake shoes, the lower door leaf area are attached, connected and via a Chain tensioner and the Torwellenritzel executed as a loop. It is a horizontal guide rail provided with a curve at the gate end.

From the above-mentioned FR 1 424 037 is a tipping door with the features of the preamble of the appended claim 1 according to alternative to a) known. The door leaf of the known tilting gate is guided at its lower edge in a horizontal running rail and at its upper edge on a horizontal running rail. At an upper horizontal Zargenholm a weight balancer is mounted with a torsion spring shaft and cable drums at the end. This torsion spring shaft is spaced at the upper tongs holm fixed bearing elements stored. With the guided through openings of the bearing elements bearing sections, the torsion spring shaft retains its position at the upper pliers spar. The torsion spring shaft engages with a central portion of two torsion springs, which attack at one end fixed to the frame and the other end to the Torsionsfederwelle. Both with the conical traction drums and with elements for attachment projects the known weight balancing device from the extension of the frame out.

task The invention is a tilt gate in the preamble of the appended claim 1 specified type with safe and quiet function over long To make the service life easier to transport and assemble.

To the Solve this The object is a tilt gate referred to in the preamble of claim 1: Art further developed by its characterizing features.

advantageous Embodiments of the invention are the subject of the dependent claims.

According to the invention is thus, as basically from the FR 1424037 known, proposed that the power source is used as a drive shaft acting preassembled drive unit with Torwelle and cable drums. In accordance with the invention, this door shaft is designed as a torsion spring shaft of a torsion spring counterbalancing device. This saves weight and thus transport costs. According to the invention, the torsion spring shaft can now be preloaded pre-assembled at the manufacturer.

Of the Installer needs at the installation already pre-assembled in the frame Just align the door and anchor the frame in the masonry to to get a ready to work gate. The torsion spring shaft itself is stored to save space on the frame. This leaves a pre-assembly of the door shaft at the manufacturer too, leaving uncertainties due to faulty mounting and the risk of injury to the assembly personnel, e.g. at the Tensioning of the spring with a torsion spring shaft designed as a Torwelle, is reducible. The weight compensation devices consist of Torsionsfederwelle and at least one traction drum, this is according to the invention in its in altitude and width direction such that they are neither sideways still upwards or in the gate opening framed by the frame seen in the direction parallel to the Zargenebene protrudes over the frame. she protrudes only in the thickness direction in the space to be closed but otherwise uses the space also required for the frame. In this way, the fully pre-assembled door can be transported to save space and fitted without difficulty at the site in the masonry opening to be closed become.

Now must the torsion spring shaft for Such an arrangement can be made particularly compact. Also the Torsion spring (s) may or may not a big one Have diameter. At the gates of the type in question is also the load of the torsion spring completely different than for example at a sectional door.

at the gates of the type in question is the weight to be compensated namely the gate while the same throughout the Torverlaufs. That's why you have so far usually also no torsion springs as weight compensation device, but uses counterweights because their force stays the same while itself the spring force of counterbalance springs constantly changes during door travel.

Corresponding the compact dimensions must the torsion spring arrangement of the gates according to the invention over a long torsion area, For example, more than 20 revolutions, be effective. For example, becomes the torsion spring is pretensioned by approx. 30 revolutions by the manufacturer. The Torsionsfederbelastung is therefore just here at the beginning of an opening movement especially high. At first tests one has to reach the compact dimensions a solid rod used as a torsion spring shaft. Due to the torsion spring load such a wave has strongly bent and an egg movement "like a Sausage "performed what to restless run, shortened Lifetime and unwanted sounds guided Has.

According to the invention will now the torsion spring shaft sections or completely executed as a hollow shaft. The Torsion spring shaft is thus completely or partially by a Tube formed. Such a tube has the same mass a larger outer diameter and a larger resistance bending moment as a full wave. As a result, on the one hand, the deflection, too when flanging a drive to the torsion spring shaft and the resulting net weight, lower. A lower deflection reduces the bearing load. Furthermore, on additional support bearings be waived.

By the use of a hollow shaft as a torsion spring shaft of a torsion spring device will the above mentioned for the Transportation and installation extraordinary advantageous embodiment and arrangement of the weight compensation device within the area covered by the frame area without disadvantages in terms of quiet running and durability allows.

For other types of gates with torsion fen derwellen the mentioned specific problems 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.

to stability the torsion spring shaft would be one possible greater Pipe diameter desirable. the but are available standing limited dimensions across from, 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 Have Zargenholmes. In particular, however, the storage of a thick Pipe problematic, because this would on the one hand for the required compact Arrangement too big Bearing elements, on the other hand, but also with the diameter rising Bearing friction forces result. According to the invention is further provided, which formed with a tubular profile torsion spring shaft with different thick sections, thicker sections, which stabilize the shaft against bending, and thinner, where the shaft is mounted. According to the invention, the shaft ends are mounted and thus the end portions of a tube profile having Torsionsfederwelle thinner accomplished as their middle section extending between the bearing elements.

The Training with thinner ones and thicker sections is possible in different ways. According to one advantageous embodiment, the torsion spring shaft is integrally formed with conical transition areas between sections of different diameters. In another advantageous embodiment, the torsion spring shaft of tubes merged with different diameters, for example, a End of a thinner pipe in a thicker tube by means of a (wedge) teeth rotation in a thicker is inserted. Instead of splines are Other non-rotatable connections (welding, splint connections, ...) for the Tubes of different diameters conceivable.

in the Principle it is sufficient to achieve the advantages of the invention also, if the torsion spring shaft only in the areas relevant for the stability tubular is trained. Nor does the tube profile need to be circular over the entire wavelength it could be also stability reasons at least in sections, other tube profile shapes (square, star-shaped, with Reinforcement approaches, ...) be used.

embodiments The invention will be described below with reference to the accompanying drawings explained in more detail. In this shows:

1 a rear perspective view of an upper corner of a single-sheet overhead tilt gate in the closed state;

2 a perspective view of a tilting the door 1 used torsion spring shaft in a first embodiment;

3 a perspective view of a second embodiment of a torsion spring shaft used in the tilting gate; and

4 a perspective view of a portion of the torsion spring shaft according to 3 ;

The embodiments described below are developments of a designated as Canopy gate tilt gate, as described in the not previously published German patent application 101 15 571.9. The tilting door described here corresponds to the formation of acting as a torsion spring shaft gate (drive) shaft in detail to that described in the 101 15 571.9 gate, so reference is made to this earlier patent application for more details. The present here 1 corresponds to the representation of 3 of the earlier patent application and shows the gate with a relevant here new embodiment of a preassembled power source unit, ie here the preassembled weight balancing device.

This in 1 Tilting gate shown accordingly has a rigid door leaf 1 and a frame 2 , On lateral vertical frame spars 3 the frame 2 are only over a portion of the lateral Zargenholme vertically extending guide rails 5 arranged. At the upper horizontal Zargenholm 6 is a power source in the form of a Torblattgewichtsausgleichseinrichtung 7 arranged. This is formed by a gate shaft in the form of a torsion spring shaft 8th , which can be used flanged to a drive, not shown, as a drive shaft. The torsion spring shaft 8th carries rope drums at both ends 9 and is opposite the Zargenholm 6 by means of a single torsion spring 10 biased.

On the rope drums 9 are left and right respectively by a wire rope 11 formed rope units a Seilzugeinrichtung held wound up. The free ends of the wire ropes 11 each attack on a fall protection device, not shown here, which slack when one of the wire ropes 11 the door leaf 1 by engaging through a series of openings 13 formed engagement formations along the guide rails 5 distributed are provided, set and in normal operation, the cable pulling force on the door leaf 1 transfers.

In 1 the gate is ready for transport from the place of manufacture to the construction site and pre-assembled for easy final assembly. There is only one spring 10 to balance the weight of the room to be closed facing the inside of the door. This is in the form of a torsion spring 10 educated.

The torsion spring 10 For example, has an inner diameter of about 30 to 40 mm, preferably about 35 mm. Therein is the torsion spring shaft 8th introduced. The torsion spring shaft 8th is with their end sections 50 in on the frame 2 fastened bearing elements 51 stored. The bearing elements 51 are essentially U-shaped with a on the frame 2 paved footbridge 52 and two each one camp 54 for the end section 50 having U-thighs 53 , The rope drum 9 is between each of the two U-thighs 53 arranged.

The torsion spring shaft 8th is tubular in the embodiments shown here as a hollow shaft. This reduces a tendency of the torsion spring shaft 8th , Under load, the uneven torsion spring bias 10 to bend.

The tubular torsion spring shaft 8th should, to have stability, have a diameter of more than 20 mm, preferably of about 25 mm or more. On the other hand, to the pipe profile equipped with Torsionsfederwelle 8th at one of its end sections 50 a drive or the like can be flanged. 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 (eg the upper frame spar). For this reason, the tubular torsion spring shaft 8th in her middle section 55 thicker (eg approx. diameter 25 mm) and towards their end sections 50 tapered executed, for example, to a diameter of about 15 mm. The torsion spring shaft 8th is at their thinner sections, ie 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. On the other hand, the large pipe profile has a stability advantage. This is particularly advantageous for (canopy) gates with drive. You have a stable tube profile in the middle and a dilute tube profile at the end.

In a first embodiment, as shown in the 1 and in the 2 showing the first embodiment of the torsion spring shaft 8th shows individually, is the torsion spring shaft 8th formed by a one-piece tube 56 , The pipe 56 shows two end sections 50 with smaller diameter, the middle section 55 with larger diameter and a conical transition area 57 ,

The production of this pipe 56 happens as follows: The pipe 56 is pulled. Between the thin and the thick diameter there is in the transition area 57 a conical transition section, the angle of the conical piece to the horizontal is about 15 to 20 °. The longitudinal extent of the conical transition amounts to, for example, 35-45 mm, preferably about 40 mm.

In the 3 and 4 is still a second embodiment of a torsion spring shaft 8th usable hollow shaft shown. It also has the thicker middle section 55 and the thinner end sections 50 on. The sections 55 . 50 different diameters are here but by single tubes 58 . 59 educated. The the end sections 50 forming thinner pipes 58 each have a spline at one end 60 on. That's the middle section 55 forming thicker tube 59 is formed at its two ends with corresponding internal toothing, in which the splined ends of the thinner tubes 58 engage in the assembled state.

The Torwellenausbildung described is also suitable for a canopy gate that does not swing, so is stored at the lower gate edge in the vertical track rail. The described weight balance device with the hollow torsion spring shaft 8th can also score at a gate in the DE 100 05 745 A1 , to which reference is expressly made for further details, described type be used instead of the counterweight compensation device provided there.
