Description

The invention relates to a Rolltoranordnung with a door leaf in the form of a tank made of angularly interconnected Torblattelementen such as slats or sections, which are each guided by rollers in lateral guides, said door leaf driven by a drive motor and between an open position and a closed position back and forth is movable, wherein the lateral guides each having a closing portion in which the door leaf is received in the closed position for closing a door opening, and a bearing portion in which the door leaf is received in the open position, and wherein the end portion and the bearing portion at an angle to each other are present and connected to each other via a transition section of the guides.

Such Rolltoranordnungen find in practice in many ways application. Particularly often they are used for closing garages, hall entrances or the like. Also in the interior of buildings, many different production areas are thereby separated from each other. For many applications, the speed of movement of such roller doors plays a special role, since this can depend on the efficiency of production processes as well as the storage and transport logistics. Conventional sectional doors are moved at speeds of between 0.3 and 0.5 m / s, whereby the upper limit for the movement speed can be found in practice at about 1 m / s. If higher speeds are desired, the door leaf is usually not formed of sections but of lamellae, which have a smaller width. The door leaf is then constructed smaller and suitable for higher speeds.

One reason for this is that the smoothness of such door leaves is generally greater when the predetermined by the width of the Torblattelemente pitch is small and the transition radius is large. Here, the so-called polygon effect plays a role Roller, which occurs when a traction means is not moved linearly, but runs over a circular arc or a different curved path. For roller doors, this is the case when the door leaf is moved back and forth between its open position and its closed position and thereby passes through a non-linear transition section of the guides. Due to the predetermined by the width of the Torblattelemente pitch these can not follow exactly the curved or curved shape of the transition portion of the guides; rather, it comes to a bending of the individual door leaf elements against each other, so that the movement of a polygon, so polygon follows. Then there are different effective radii in the transition section and, accordingly, a periodic fluctuation of the movement speed about a mean speed or rated speed. This results in undesirable excitations in the longitudinal and transverse directions of the traction device, which lead to vibrations.

As the door leaves of roller shutters usually do not constitute a circulating system, the individual door leaf elements are not connected directly to the drive. Here, the polygon effect in particular to the effect that vibrations of the rollers or Torblattelemente occur in the direction of movement and complicate optimal operation of these Toranordnungen. This considerable noise developments as well as loads on the components of the door leaf are connected, which adversely affects their life. Therefore, the maximum speed of movement for opening and closing the door assembly is limited here.

The problem was already addressed by the WO 2014/114528 A1 , The roller shutter element which emerges from this prior art has vertically aligned end sections of the lateral guides, which open into a spirally formed bearing section in the lintel area. In order to reduce the above-mentioned disadvantageous effects of the polygon effect in the transition region between these guide sections, this document proposes to provide an additional guide device, which serves as a kind of further transition section and here additionally guides the door leaf. The basic problem of forming a polygon in this transitional section by bending the individual Gate leaf elements to each other, however, is eliminated neither here in the transition section nor for the subsequent spiral section of the lateral guides. Therefore, this proposed solution was very limited in order to achieve a reduction of the polygon effect.

In addition, also the EP 1 923 533 A2 with this problem. In the case of this roller door, it is provided in the light of said kinematic problems to guide the door leaf in the course of the opening movement of the vertical sections of the lateral guide via a transition section in spirally extending guide rails in the lintel area and to allow a non-contact winding of the door leaf. In addition, this should also be avoided when winding on a winding shaft and responsible for the noise and vibration development polygon effect. In practice, however, it has been shown that this succeeds only to a limited extent, since, due to the system, the width of the given lamellae and their angled position relative to one another in the transition region necessarily causes a considerable fluctuation in the speed of movement of the individual lamellae around an average speed. The associated acceleration and deceleration effects on the individual Torblattelementen lead to massive wear on the management bodies and a significant noise. This can conventionally be counteracted only by keeping the speed of movement low.

From the document DE 20 2014 104 547 U1 a Venetian blind with several hingedly connected to a chain slats has become known, which discloses the features of the preamble of claim 1. The present invention is based on this prior art.

The present invention was therefore based on the object to improve a generic Rolltoranordnung such that the so-called polygonal effect is at least largely prevented and thereby higher movement speeds of the door leaf are possible.

This object is achieved by a roller shutter arrangement with the features of claim 1. This is characterized in particular by the fact that the transition section of the guides in each case provides at least two guide lines, on which roll off predetermined rollers, so that here the guide length between two Rollers substantially corresponds to the defined by a width of a Torblattelements division or an integer multiple thereof.

In the context of the invention, it was recognized that the vibration behavior of the speed of movement about a rated speed has the reason here in the kinematics of the guide. Thus, the guide length between two considered rollers of the roller door arrangement changes depending on whether these rollers are moved in rectilinear guides or in a transition section, which forcibly has a predetermined curvature, usually a constant radius. However, since the door leaf is operated altogether at the predetermined nominal speed, the roller or lamella speed in the transition section of the guides initially increases locally in comparison therewith, whereby the local movement speed then also becomes smaller than the rated speed due to the oscillation behavior caused thereby. The thus excited vibration of the movement speed thus leads to acceleration and deceleration effects, which are not limited to the transition sections of the guides, but also cause effects beyond.

Investigations in the course of the invention have further shown that the number of oscillations on the observed roller or on the corresponding door leaf element is equal to the number of door leaf elements of the door leaf, which follow the observed roller or Torblattelement and enter the transition section of the guides. The magnitude of the vibrations of the velocity and the acceleration depend on the nominal velocity, the radius in the transition section and the pitch.

To solve this problem, the present invention proposes now for the first time to adjust the effective guide length between two rollers in the transition section of the guides so that this corresponds to the defined by the width of the Torblattelements division or an integral multiple thereof. This is achieved according to the invention by providing at least two guide lines in the transition section of the guides, on which predetermined rollers so one part of which follows one guide line and the other part of which follows at least one other guide line. In the exemplary embodiment with two guide lines, adjacent rollers then roll, for example, on the respective other guide line.

In the context of the invention, therefore, the rollers in the transition section of the guide are not for the first time all guided on a single track, but go through different paths, whereby the known in the prior art increased path length for the individual rollers in the transition section is just avoided. The effective guide length in the direction of movement of the door leaf as a whole can then be shortened. The gate leaf elements can then locally kink against each other to a greater extent. The actual movement path to be traversed for the individual rollers or door leaf elements therefore corresponds, according to the invention, to that in a rectilinear guide, so that no acceleration or deceleration of the movement speed is caused. A polygon effect is reliably avoided or at least largely suppressed.

In this way, according to the invention, it is achieved that the disadvantageous oscillation of the speed in the direction of movement known from the prior art is eliminated. This improves the stability of the Torblattbewegung and it is uniform. At the same time reduce the periodic loads on the door leaf and its individual structural parts, whereby they are subject to less wear and achieve a longer life.

Furthermore, the invention can be carried out even with limited space in the gate lintel area, since the provision of the at least two guide lines requires little space. The lintel height can therefore be kept low in the roller door assembly according to the invention, so that a large clearance height, etc. remains. This allows so-called low-fall gates thus perform particularly advantageous.

Another advantage of the present invention is that it also significantly reduces noise during operation of the rolling door assembly. At the same time, therefore, the roller shutter arrangement can be operated at a significantly higher opening or closing speed than was still possible in the prior art.

This is especially true for so-called sectional doors, the door leaf elements have a greater width - and thus larger pitch of the door leaf - than the slats in a slatted gate. Practical experiments have shown here that even the door leaf of such a sectional door with speeds up to 2.5 m / s is movable.

Advantageous developments of the invention Rolltoranordnung are the subject of the dependent claims.

Thus, the transition portion of the guides each have at least two laterally offset from each other arranged guideways, wherein predetermined rollers on the door leaf elements corresponding axially offset from each other and engage in an associated guideway. In this way, the basic idea of the invention can be implemented constructively with very little effort in practice. Following rollers on the door leaf can here be e.g. alternately guided on one guideway and the other guideway. At the same time, such web-like guides are characterized by an exact, reliable and stable design, which allows a high degree of smoothness. This allows even higher speeds of movement for the operation of the door leaf can be achieved. In addition, the wear is low, so that a long life of the construction elements can be achieved.

If the door leaf elements have additional rollers which are hinged to the adjacent rollers of the door leaf element via hinges or joints and roll on a different guideway in the transition section than the adjacent rollers, the at least two guide lines can be guided closer together in the transition section of the guides the transition section requires less space. This can be the Reduce or avoid polygon effect with low design effort particularly reliably.

Furthermore, it is also possible for one of the guide lines in the transition section of the guides to follow a constant transition radius between the end section and the bearing section of the guides. Then, this guide line can be provided in a conventional manner as in a conventional roller door. It is then merely the at least one further guidance line, which deviating from this is to be designed. The cost of producing the transition section of the guides is then low.

Further, one of the guide lines in the transition portion of the guides may be radially outward of a constant transition radius between the end portion and the bearing portion of the guides. In this construction, the at least two guide lines can be guided close to each other, whereby the space required for the transition section can be kept low. In addition, this embodiment is associated with a particularly high degree of smoothness for the movement of the door leaf.

Alternatively or additionally, one of the guide lines in the transition section of the guides can also be present radially within a constant transition radius between the end section and the bearing section of the guides. This embodiment has the advantage that the transition section can be made particularly compact, since no radially outwardly projecting projection is required for the provision of this guide line.

Furthermore, the polygonal effect can also be avoided particularly reliably if the bearing section of the guides is rectilinear. Then no tilting of the individual door leaf elements occur here, so that the effective guide length here corresponds automatically to the pitch of the door leaf elements.

If the drive transmits the driving force in the area of a Torblattelements on the door leaf, can be made of a proven drive system for such a roller shutter arrangement. This is characterized by a particularly high level of operational reliability and reliability.

It is preferred if the drive transmits the driving force to a bottom-side door leaf element on the door leaf. This mode of operation has proven itself very well in practice and can be used particularly advantageously in connection with the present invention.

In this case, the roller shutter arrangement can be designed as a high-speed lifting gate. This form of use is the vast majority in practice. Here are the advantages in terms of high smoothness and durability and especially the high operating speeds particularly beneficial.

In Fig. 1 is shown a sectional side view of a roller door assembly 1 according to the invention. This has a door leaf 2, which is guided on both sides in the region of a frame 3 in a guide 4. The door leaf 2 is driven by a drive 5 motor.

The guide 4 includes a closing portion 41, which is vertically aligned in the embodiment shown and the door leaf 2 receives in its closed position present. At this end portion 41, a transition section 42 connects, which opens into a bearing portion 43. The latter extends horizontally in a straight line under a ceiling of a building, not shown here. A mirror-image trained leadership is on a correspondingly shaped frame also on the opposite Torseite arranged. The two guides thus take up the lateral ends of the door leaf 2 between them and guide them.

To open the roller door assembly 1, the door leaf 2 is moved from the end portion 41 via the transition portion 42 in the bearing portion 43, wherein it remains in the open position.

Fig. 2 shows a detail view from the illustration in Fig. 1 from which the transition portion 42 of the guide 4 shows more clearly. The door leaf 2 is omitted here, however, to ensure a better overview.

The transition section 42 has an inner guide element 421 and an outer guide element 422. These offer the later still to be explained rollers at the lateral ends of the door leaf 2 in each case two guideways, so that a part of the rollers rolls on one guideway and the other part on the other guideway.

On the inner guide element 421, this is the first inner guide track 421a, which is concealed in the present side view and is therefore inscribed in dashed lines, and the second inner guide track 421b. On the outer guide member 422, this is the first outer guideway 422a and the second outer guideway 422b. As can be seen from the illustration, the second inner guideway 421b and the second outer guideway 422b each extend radially outward of the associated first guideway 421a and 422a. The interaction of these guideways with the sections 21 of the door leaf 2 will be explained later in more detail.

In Fig. 2 Furthermore, a motor 51 of the drive 5 is still recognizable and a drive shaft 52, by means of which the engine power is transmitted in a conventional manner from one gate side to the other.

A perspective view of the illustration according to Fig. 2 is in Fig. 3 shown. In particular, the guideways 421a, 421b, 422a and 422b can be seen more clearly here. In addition, further details of the door leaf 2 can be seen.

This has a plurality of mutually angled sections 21, which extend transversely across the door opening and are connected on both sides in the end region by a hinge strap 22. In the hinge area while rollers 23a and 23b are arranged, which roll on axes of rotation 24a and 24b. The axes of rotation 24a and 24b are extensions of the hinge pins.

The structure of the door leaf 2 goes out in more detail yet Fig. 4 which is a front view thereof. From this as well as from the detail according to Fig. 5 is clearly seen that the rollers 23a are mounted on longer axes of rotation 24a, as the rollers 23b on the shorter axes of rotation 24b. The rollers 23a are thus in the region of the guide 4 axially offset from the rollers 23b. In the effective diameter, however, the rollers 23a are identical to the rollers 23b, as shown in the side view Fig. 6 is recognizable.

In Fig. 4 Furthermore, two drivers 25 are shown, which are fastened on both sides on the door leaf 2 on a bottom-side section 21. These drivers 25 interact with the drive 5 in such a way that the driving force is transmitted at this point to the door leaf 2 synchronously on both sides. For operation of the door leaf 2, the majority of the sections 21 are thus pushed when opening in the bearing portion 43. When closing the door leaf 2, however, this is pulled out of the bearing portion 43 out into the closed position in the end portion 41.

To clarify the essence of the present invention, the following will first be described below with reference to a schematic representation of the trajectory of a door leaf of a conventional roller door arrangement in FIG Fig. 7 basic aspects presented:

Fig. 7 schematically shows a conventional door leaf TB of a plurality of angularly interconnected sections S. The effective width of a section S is the Division T of the door leaf 2, which is equivalent to the distance of two hinges which connect the sections S pivotally together or the distance of two rollers LR.

This door leaf TB is laterally guided by means of the rollers LR in a guide, not shown here, which is divided into the areas vertical guidance VF, transitional guide ÜF and horizontal guidance HF. The vertical guide VF and the horizontal guide HF are formed in a straight line. The transitional guide UF has a constant radius R and connects the vertical guide VF with the horizontal guide HF.

In Fig. 7 Furthermore, the guide line FL of this conventional door leaf TB is shown, which is shown in dash-dotted lines. As can be seen from this, an effective, here dotted clarified guide length L between two rollers LR in the transition area ÜF longer than in the linear areas of the vertical guide VF and the horizontal guide HF, since it is not linear, but runs over a circular arc , The effective guide length L is here therefore greater than the pitch T.

This has the consequence that a nominal velocity v _Nenn of, for example, a constant 2 m / s initiated on the bottom side via a section S is transferred to the further sections S in the present exemplary embodiment and does not appear uniformly at the other end of the door leaf due to the polygon effect. but as the resulting velocity v _{R is} subject to considerable fluctuation. This is in the diagram according to Fig. 8 clarifies which shows the speed over time.

Fig. 9 shows the associated diagram of the effective accelerations over time, which act on the sections S of the door leaf TB. Without the influence of the polygon effect, a nominal acceleration in the direction of movement a _nominal of 0 m / s ^{2 would be} given. Due to the polygon effect, however, it comes to accelerations and Delays, which are reflected in the diagram in the resulting acceleration a _R.

The present invention provides a different type of guide in the region of the transition section 42. As in particular already on the basis of Figures 2 and 3 has been illustrated, the transition section 42 here, the inner guide member 421 and the outer guide member 422, which provide two guide lines 423 and 424 due to the design of their guideways. In Fig. 10 this is shown schematically in side view. The first guide line 423 corresponds in the illustrated first embodiment of a conventional guide line in a transition guide with a constant radius as they are made Fig. 7 it can be seen, while according to the invention still the second guide line 424 is added, which is present radially outwardly thereof. The second guide line 424 also extends in the present embodiment, not only on the transition section 42, but extends around each of the extent of the pitch T in the end portion 41 and the bearing portion 43 inside.

It can be seen that the rollers 23a and 23b are guided in the region of the transition section 42 alternately on the first guide line 423 and the second guide line 424. In this case, the rollers 23a follow the first guide line 423 and the rollers 23b of the second guide line 424. In other words, the sections 21 buckle here alternately in a predetermined manner exceptionally, whereby a guide length shown here dotted 425 of two on a guide line 423 successive rollers 23a has a dimension which corresponds twice to the pitch T.

Thus, the sections 21 of the door leaf 2 are not subject to any effective extension of their movement path even in the transition section 42, so that the polygon effect can be suppressed or prevented here. Fluctuations in speed or acceleration, as in the prior art still in the FIGS. 8 and 9 are shown can thus be avoided.

A modified second embodiment of the present invention is in Fig. 11 shown. This differs from the design according to Fig. 10 only in that a second guide line 424 'is present radially within the first guide line 423. The further details of this arrangement correspond to those of the first embodiment, and therefore the same reference numerals are used for the corresponding elements.

Again, the sections 21 buckling each other in a predetermined manner exceptionally from each other, whereby the dotted guide length shown here 425 'of two on a guide line 423 successive rollers 23a has a degree which twice the pitch T corresponds. Thus, the polygon effect can be equally suppressed.

In Fig. 12 a third embodiment of the invention is shown. Here have sections 21 "in addition to their edge-side arranged rollers 23a and 23b, an additional roller 23 c", which is present between them and is coupled to a hinge not shown here. It is here spaced by a predetermined amount mt from the roller 23a. In this way, a section 21 "can additionally be angled in a predetermined manner within its inherently fixed width, so that a smaller section width becomes effective in the transition section 42. The additional roller 23c" in each case runs on a second guide line 424 " then approach even closer to the first guide line 423, but is located radially outside thereof.

The dotted drawn effective guide length 425 "between two rollers 23a and 23b thus corresponds to the pitch T. Hereby, the polygon effect can be suppressed.

In Fig. 13 a fourth embodiment of the invention is shown. Here have sections 21 '''in addition to their edge-side arranged rollers 23a and 23b on an additional roller 23c''', which is here preferably centrally with a measure mt = T / 2 between them and with a hinge not shown here is coupled so that both edge-side arranged rollers 23a and 23b can be pivoted relative to this. A remaining, the sections 21 '''further directly connecting pivot axis 26''' between two adjacent sections 21 '''then forms in the transition section 42 together with two additional rollers 23c''' and a roller 23a or 23b a shape by type a four-link.

In this way, a section 21 '' 'within its per se fixed width can be angled again, so that in the transition section 42, a smaller section width is effective. The additional roller 23c '' 'in each case runs on the first guide line 423, while the rollers 23a and 23b run on a second guide line 424' ''. This lies radially within the first guide line 423. The pivot axes 26 '' 'in turn on a further guide line 426' '' radially outside the first guide line 423 from.

The dotted line shown effective guide length 425 '' 'between two rollers 23c' '' then corresponds to the pitch T. Again, the polygon effect can be suppressed.

In all these embodiments, the rollers are guided in the region of the end portion 41 and the bearing portion 43 as usual on a common guideway.

In addition to the embodiments shown, the invention allows for further design approaches.

So it is also possible that more than two laterally staggered guideways are formed at the transition portion of the guides. For this purpose, the rollers 23a or 23b may be formed, for example, as double rollers, the individual roles in this case at a distance from each other, but on a common axis of rotation and thus cooperate with each guideways, which the other guideway of each other rollers on both sides embrace. As a result, a smoother running is achieved. In principle, it is also possible to design three or more separate guideways.

In the embodiments shown, one of the guide lines in the transition portion of the guides each followed a constant transition radius between the end portion and the bearing portion of the guides. However, this is not mandatory. It is also possible to provide one of the guideways radially outwardly therefrom and the other radially inwardly thereof. Finally, the guideways can be made more or less arbitrary with respect to a given by the transition radius transition line. The configuration of the guide lines is then calculated from the transition line and the division T.

Furthermore, the bearing portion of the guides need not necessarily be formed straight line. Here it is also possible, for example, to provide an elongated or circular winding for receiving the door leaf, as they are known from DE 40 15 215 A1 and the WO 00/60208 A1 have become known. Also bearing sections with other radii gradients or variations are possible.

The driving force of the drive 5 does not necessarily have to be transmitted to the lower, bottom-side door leaf element in the door leaf. The introduction of force can also take place at the upper end of the door leaf or at another suitable place by suitable means.

The rolling shutter arrangement according to the invention is not limited to being designed as a high-speed lifting gate. It can also be used in other installation situations, as long as the end portion 41 and the bearing portion 43 are at an arbitrary angle to each other. In addition, thereby manufacturing areas, machining centers, etc. may be completed within factory halls or the like of the environment.
