Description

The invention relates to a rolling gate comprising a gate leaf that can be moved between an open position, in which it at least partially clears a wall opening and forms a multi-layered roll above the wall opening, and a closed position, in which it at least partially closes the wall opening, and articulated structures for guiding the movement of the gate leaf which are located in the region of the lateral edges of the gate leaf that run at least in sections in the direction of gravity in the closed position and fastened to the gate leaf, each of which articulated structures have a plurality of articulation members connected to one another flexibly in relation to articulation axes running perpendicular to the lateral edges and approximately parallel to the plane of the gate leaf.

Such rolling gates are described, for example, in DE 10 2009 017 767 A1. They are used inter alia as so-called high speed gates for closing industrial buildings. It is important here, on the one hand, that the movement of the gate leaf is guided reliably. On the other hand it is significant that often only a small amount of space is available for accommodating the gate leaf in the open position. In view of these requirements, in the aforementioned specification a rolling gate is already proposed in which at least one articulated structure has at least one articulated plate positioned on a front face, running approximately perpendicular to the articulation axis, of a rigid gate leaf element made, for example, as sandwich elements, and fastened to the latter. In this way enlargement of the thickness of the overall construction by the articulated structure can be avoided, and the space requirement for rolling gates in the open position can be reduced. However, it has been shown that corresponding gates are still associated with a considerable space requirement and the speed of movement of the gate leaf is restricted.

Gates according to the preamble to Claim 1 are specified in DE 10236648 A1 and DE 20320336 U1.

In view of these problems in the prior art the object underlying the invention is to provide a rolling gate which can be supported in the open position with a small space requirement and enables a high opening and closing speed, at the same time ensuring reliable guidance of the gate leaf movement.

According to the invention this object is achieved by the further development of the known gates specified in the characterising part of Claim 1.

Making at least sections of the gate leaf from flexible material enables a reduction of the space requirement because the material itself adapts to the roll that forms in the open position, and so enables a small spiral diameter in the open position. At the same time, by means of the stabilisation devices of the gate leaf a robust gate leaf is realised. The gate leaf is guided with the aid of the articulation members of the articulated structures coupled to the stabilisation devices, by means of which the pulling and pushing forces which occur when the gate leaf is moved can be transmitted via the articulated structures. The gate leaf can be made to be correspondingly light. One only needs to ensure that the stabilisation devices of the gate leaf are coupled securely to the articulation members of the articulated structures.

Commercially available, preferably transparent PVC and/or polycarbonate can preferably be used as flexible material for the production of gates according to the invention. The strength of the plastic track is chosen in accordance with the requirements. In any case, using the flexible material in the form of a plastic film or track can ensure adaptation of the shape of the gate leaf to the spiral shape in the open position by guaranteeing a small roll radius.

Polycarbonate in particular has proven to be a material with excellent properties for use in gates according to the invention. The material has a high degree of elasticity with sufficient flexural rigidity so as to follow the roll contour, even with large widths. In addition, the material has additional positive properties such as, for example, high resistance to impact.

Therefore, by means of the rolling gates according to the invention the advantages of a rolling gate construction with rigid slats and lateral articulated structures are combined with the advantages of film gates so as to thus provide a high speed gate which enables a high opening and closing speed by means of the flexible construction of the gate leaf, at the same time making available reliable guidance by means of the articulated structures and relief of the gate leaf by transmitting pushing and pulling forces via the articulated structures. The connection of the gate leaf to the articulated structures can be realised in a particularly stable manner here because stabilisation devices provided to prevent bulges due to wind pressure can in any case be used for this purpose.

In a preferred embodiment of the invention the gate leaf has a segment (also referred to in the following as a “slice”) made of preferably transparent and bendy or flexible material with segment or slice edges running approximately perpendicular to the lateral edges of the gate leaf, the segment or slice edges being provided with a thickening and at least one stabilisation device having a stabilisation profile with at least one receiving region for receiving the thickening on one segment or slice edge. The stabilisation profile extends preferably over the entire width of the gate leaf in a direction perpendicular to the lateral gate leaf edges, the receiving region also advantageously extending over the entire width of the gate leaf. In addition or alternatively, at least one segment edge can be made without a thickening and can be held by material engagement and/or with force locking, such as for example by means of a clamping strip, to the stabilisation device.

The stabilisation profile can be made, for example, as an extruded plastic profile. In a particularly preferred embodiment of the invention the stabilisation profile is, however, made as an extruded aluminium profile. This type of extruded aluminium profile combines high strength with low weight.

The thickening on the segment or slice edges can be realised by stuck on or welded on beading strips which are received with form-fitting in corresponding receiving regions of the stabilisation profiles. In addition, however, one can also consider other connection possibilities, for example by means of a clamping strip, in order to be able to change the bendy or flexible segments easily in the fitted state.

In rolling gates according to the invention the gate leaf is only connected to the articulated structure by means of the stabilisation profiles also serving as wind bracing, which articulated structure can be realised, for example, as a hinge strip. The hinge points of the articulated structure or of the hinge strip lying in between are not connected to the flexible material. The hinge strip or the articulated structure absorbs the pushing and pulling forces in the course of the opening and closing movement. The connection of the stabilisation profiles or wind braces to the hinge strip can take place in any way within the grid of hinge points. Different segment heights can thus be produced. With narrow gates the number of stabilisation profiles or wind braces can be chosen to be smaller, i.e. the section height can be particularly large, whereas wide gates can be equipped with a number of stabilisation profiles or wind braces with a smaller section height for stabilisation.

Structurally, it has proven to be advantageous if the door leaf has at least two segments made of flexible material arranged one behind the other in the direction of movement of the gate leaf, between which segments is located a stabilisation profile with two receiving regions for receiving thickenings provided on disc edges facing one another. With the stabilisation profile the connection between consecutive segments made of flexible material is therefore brought about.

According to the invention provision is made such that at least one stabilisation device extends over the entire width of the gate leaf approximately parallel to an articulation axis. Trouble-free connection of the stabilisation device is achieved according to the invention without any negative impact upon the moveability of the articulated structure because the stabilisation device is connected along the articulation axis to at least one, preferably to two articulated structures provided on lateral gate leaf edges opposite one another.

In particular, with particularly high and/or wide gate leafs, with regard to the desired stabilisation it has proven to be advantageous if at least one reinforcement strip extending approximately parallel to the lateral edge of the door leaf and fastened to the gate leaf is provided. By using appropriate reinforcement strips which can also, for example, be stuck on and/or welded onto the segments of the gate leaf, sufficient overall stability can also be achieved if the material of the segment itself does not provide sufficient flexural rigidity.

Similarly to the rolling gates described in DE 10 2009 017 767 A1, at least one helical guide track can be assigned to a rolling gate according to the invention with a flexible gate leaf for guiding the movement of the gate leaf and for determining the open position of the gate leaf, at least one articulation member having on its side facing away from the gate leaf a guide roller rotatably mounted relative to a roller axis running parallel to the axes of articulation, which guide roller is preferably received, at least in the open position of the gate leaf, in a guide track.

In addition to the normal helical guide track, alternative guide tracks, such as an oval spiral, a horizontal deviation or also a vertical guide can also be produced, depending on the space requirement on the structure.

In the following the invention will be described with reference to the drawings to which reference is explicitly made with regard to all of the details which are essential to the invention and which are not pointed out in more detail in the description. The drawings show as follows:

Fig. 2 a partially sectioned side view of a rolling gate according to the invention in the transition from the closed position into the open position,

Fig. 3 a detailed illustration of the gate leaf of a rolling gate according to the invention, and

Fig. 4 a detailed illustration of the rolling gate according to Fig. 1.

The rolling gate illustrated in Fig. 1 comprises a gate leaf identified as a whole by 10, which is formed from segments 12 made of flexible, transparent material which are connected to one another by stabilisation profiles 40. Disposed on the lateral edges of the gate leaf 10 are articulated structures in the form of hinge strips 20 and 30 which are connected to the gate leaf 10 by means of the stabilisation profiles 40. The hinge strips have on the articulations between the individual hinge members on their side facing away from the gate leaf 10 guide rollers 22 or 32 with which the movement of the gate leaf can be guided using appropriate guide tracks.

According to Fig. 1 the hinge strips 20 or 30 forming a push/pull unit are formed from hinge members 26 or 36 which have on their one end a bracket-shaped receiver or comparable design in which a pin of an adjacent hinge member engages. A common hinge pin passes through the bracket and the pin so as to thus bring about a flexible connection between consecutive hinge members. The roller axes of the guide rollers 22 and 32 run parallel to the articulation axes, preferably collinearly with the latter. Likewise, the stabilisation profiles 40 made as extruded aluminium profiles run parallel to the articulation axes or roller axes. The stabilisation profiles 40 can be connected to the articulation structures 20 or 30 at the pivot points of the hinge strips.

According to Fig. 2 a rolling gate according to the invention has a helical guide track 100 into which the hinge strips 20 and 30 move upon reaching the open position. In Fig. 2 the hinge members 26 and 36 are blocked out in the region of the helical guide track so as to thus be able to achieve a better illustration of the gate leaf itself. It can be seen that segments made of flexible material can easily adapt to the desired helical shape. For this purpose it is not necessary either for the segments themselves to be connected to the hinge strips. In fact it is sufficient if only the stabilisation profiles 40 are connected between the individual segments to the articulated structures in the form of the hinge strips 20 and 30. Furthermore, one can see that the individual segments of flexible material can extend over a considerable height of the gate leaf. This is a particular advantage in comparison to conventional slatted gates by means of which minimisation of the spiral diameter is made possible.

According to Fig. 3 the segments 12 have thickenings formed by welded-on beads 14 on the segment edges running perpendicular to the lateral edges, which thickenings are received in the receiving regions 42 and 44 of the stabilisation profiles. The width of the receiving regions 42 and 44 tapers from the receiving regions 42 and 44 in the radial direction such that in their outlet regions the receiving regions only enable the segments 12 to be passed through with stuck on beading lugs, but do not enable the thickenings or beads 14 to be passed through. In this way a secure connection of individual segments by means of the stabilisation profiles 40 is achieved. However, no pulling or pushing forces are to be transmitted via this connection. Said forces are transmitted via the hinge strips 20 or 30.

According to Fig. 4 the hinge strips 20 or 30 are connected by means of the stabilisation elements 40 with the aid of a screw running collinearly to the roller axis of the guide rollers 22 or 32, which screw is secured with a lock nut 50. The screw engages in a corresponding recess 52 (see Fig. 3) in the stabilisation profiles 40. It can be seen in Fig. 4 that the articulation axis of the flexible connection runs approximately collinearly between consecutive hinge members 26, the roller axis, the screw axis and the axis of the stabilisation profile 40.

The invention is not restricted to the embodiment illustrated by the drawings. In fact, it is also conceivable to provide additional stabilisation strips parallel to the lateral edges of the gate leaf so as to thus achieve additional stabilisation with respect to wind pressure. The push/pull units made in the form of hinge strips in the embodiment described may also be designed in a different way. The connection of the stabilisation elements to the push/pull unit may also be made flexibly such as to avoid a rigid connection. In this way a floating mounting is created which helps to prevent the transmission of torsional forces from the rolled up segments to the push/pull unit.
