Description

The invention relates to a roller door. Furthermore, the invention relates to a damping body for a roller door.

DE 10 2010 022 172 B3 discloses a roll-up door with a winding shaft and formed from double-walled roller shutter rods formed on the winding shaft to a wound bale roller shutter. The Rolltorpanzerstäbe are composed of a metal half-shell and a plastic half-shell and serve the noise insulation and thermal insulation. On the plastic half shell elevations are inseparable molded to reduce rattling noises.

DE 197 11 318 A1 describes a roller shutter for doors or windows. The slats of the curtain are made of plastic and cause crackling noises when rolling up and unrolling. Blocks attached to the lamellas increase the static friction and thus prevent a relative displacement of overlapping lamellas to one another.

DE 89 07 445 U1 discloses a sound-deadened aluminum hollow section bar. The hollow profile bar is coated with a noise-reducing paint coating.

WO 2009/148460 A1 refers to high speed doors. On the roller shutter damper elements are applied to the edge hinges.

US 2004/0163777 A1 discloses a high-speed door with lateral rolling elements. The rolling elements have a sound absorbing material and allow a spiral winding of the Rolltorpanzers.

During winding, the stacked roller shutter rods cause noise. Likewise, the roller door surface can wear out. The aforementioned roller doors are provided with noise-reducing measures. In practice, however, numerous roller shutters are installed, which have no noise reduction measures. The retrofitting with the aforementioned known measures usually requires the complete disassembly of the roller door or even a separate production of a new roller shutter door. This is complicated and expensive.

The invention has for its object to improve rolling doors in terms of noise and wear behavior.

The object is solved by the features of the independent claims. Advantageous developments are the subject of the dependent claims.

The invention provides a roller shutter with a winding shaft, with a formed of metal, prefabricated roller shutter rods formed on the winding shaft to a roll bale roller shutter and with a set of damping bodies, which are formed of a plastic foam material elastomeric material and / or textile material and the solvable to the roller shutter rods are fastened.

It is preferred that at least one, preferably all, damping body has / have an adhesive surface for adhering to a first roller shutter bar.

It is preferred that at least one, preferably all, damping body has / have a contact surface for application to a second roller shutter bar.

It is preferred that at least one, preferably all, damping bodies are designed to rest in the wound-up state with the contact surface only on a single second roller-armor bar.

It is preferred that at least one, preferably all, damping body is adhered to one of the roller shutter rods.

It is preferred that at least one, preferably all, damping body is arranged on a roller shutter winding side, preferably an inner side, which is wound up facing the take-up of the winding shaft.

It is preferred that at least two, preferably all, damping bodies are arranged adjacent to each other along the vertical direction.

It is preferred that at least two, preferably all, damping bodies have no offset in the horizontal direction.

It is preferred that damping bodies are arranged on all rolling shutter rods, wherein preferably at least one damping body, in particular all, damping bodies on a Rolltorpanzerwickelseite, preferably an inner side, is / are arranged, which is wound up during winding of the winding shaft.

The invention provides a remote damping body for a previously described roller shutter with fastening means for releasably adhesive bonding of the damping body.

The invention further provides a set of damper bodies for a roller shutter with attachment means for releasable, adhesive attachment of the damper body.

Preferably, the damping body has one of the aforementioned embodiments.

Furthermore, the invention proposes the use of a set of preferred damping bodies for reducing operating noise of a roller shutter door.

Hereinafter, possible advantageous effects of the invention will be described.

An elastic element is an example of a damping body.

Elastic elements, for example, made of plastic foam, are applied to the blinds of a roller shutter so that their elastic behavior produces a damping effect during the juxtaposition of the individual Rolltorprofile.

The invention is based on the finding that in a roll-up door the profiled bars, which lay down and lay down one after the other during winding, are a cause of the formation of noises and signs of wear on the curtain / profile surface.

With the invention can be achieved that at the same curtain speed, the energy of the juxtaposition of the profile bars is attenuated. The reduced impact energy reduces the noise and protects the surfaces of the colliding roller shutter profile bars.

An advantage of the invention is the applicability also to rolling doors already in operation (also from third-party manufacturers), the individual / targeted mountability (possibly only on the most heavily loaded profiles), the relatively simple, residue-free removal of the elements and the effects on the Rolltor which indirectly allows a possible increase in performance (speed increase, service life increase, etc.).

The elements for attachment to or on the roller door curtain have an elastic / resilient behavior.

The height of the elements is chosen to produce as early as possible a damping behavior and at the same time not to affect the bale diameter and thus the rolling tordynamics too much.

The elements are preferably individually, adhesively attached to the Rolltorprofil.

The elements can act on each Rolltorprofil individually.

The elements are removable again.

The elements can also be used for a retrofit solution to third-party products.

As elastic elements, for example, foam pads are glued to an existing Rolltorprofil.

This allows improved noise insulation and retrofitting can be achieved.

In addition, an influence on the wind stability is reduced / minimized.

It can be achieved a reduction of the total operating noise.

The buffering takes place for example by elastomers, foams and / or textile fibers on the hall side of the curtain.

A coating of the profiles of the curtain can be avoided, in addition, an execution of the profile can be avoided in two different types of material.

In addition, an execution of the profile in two different types of material can be avoided.

The roller shutter profiles are supported / damped on a "visible inside".

A roll-up door 10 comprises a winding shaft 12 and a roller shutter door 14. The roller shutter door 14 is guided in a roller shutter guide rail 16. The roller shutter 14 is wound on the winding shaft 12 to a winding bale 18 to open the roller shutter 10. The wound bale 18 has a wound bale diameter d in the wound state.

The roller shutter tray 14 has a roller shutter shell side 20, a roller shutter outer side 22, a roller shutter closing edge 24, and a roller shutter shell shaft side 26. The roller shutter shell side 20 is the side of the roller shutter shell 14 wound on winding of the winding shaft 12. The roller shutter outer side 22 is disposed opposite to the roller shutter shell side 20. The roller shutter closing edge 24 is defined by the lowermost edge of the roller shutter 14. The Rolltorpanzerwickelwellenseite 26 is provided on the Rolltorpanzerschließkante 24 opposite to the winding shaft 12 located uppermost edge.

The roller shutter 14 is composed of roller shutter rods 28. The roller shutter rods 28 are hinged together. The roller shutter rods 28 are formed from a metal roller shutter hollow profile 30 and a roller shutter hollow section foam 32. The rolling shutter hollow profile 30 has a concave curved concave side 31 and a convex curved convex side 33 facing each other.

It is also possible that roller shutter profiles may be used instead of the roller shutter hollow profiles 30 as roller shutter rods 28. The roller shutter profile may also be curved like the roller shutter hollow profile 30. It is also conceivable that the roller shutter hollow profiles 30 or the roller shutter profiles have a substantially rectangular or box-like profile.

On the Rolltorpanzerwickelseite 20 damping body 34 are provided. The damping body 34 comprises fastening means 36 and contact means 38. The fastening means 36 are designed to fasten the damping body 34 to the roller shutter winding side 20. The contact means 38 are designed to come into contact with the roller door outer side 22.

The damping body 34 is formed from a plastic foam body 40 which is elastically deformable and formed from a plastic foam material. Other materials that can be used are, for example, elastomeric material and / or textile Fibers. The plastic foam body 40 has an adhesive surface 42 and a contact surface 44.

The adhesive surface 42 is used for sticking the plastic foam body 40 to one of the rolling shutter rods 28. The adhesive surface 42 is formed such that a removal of the plastic foam body 40 without substantial residues is possible.

The contact surface 44 is formed when winding the Rolltorpanzers 14 on the winding shaft 12 to detect a Rolltorpanzerstab 28.

The plastic foam body 40 is formed as a polymer foam body 45 of a foamed polymeric material and in particular as an elastomeric foam body 46, which is made of a foamed elastomeric material. The elastomer foam body 46 is formed in particular as a parallelepipedic foam pad 47 made of a foam material.

In the assembled state, the damping body 34 is fastened by means of the fastening means 36 to a first roller shutter bar 48. Upon winding, the contact means 38 contacts a second roller shutter bar 50. In one embodiment, a damper body 34 is formed and disposed on the first roller shutter bar 48 such that the contact means 38 are in wound contact with exactly one second roller shutter bar 50. In a further embodiment, the contact means 38 contact the hinge area between two adjacent roller shutter bars 48.

The damping bodies 34 are provided in an embodiment on each Rolltorpanzerstab 28. The damping bodies 34 are arranged adjacent to each other in the vertical direction. The damping bodies 34 have no offset in the horizontal direction. In a variant, the damping bodies 34 are arranged in five vertical rows without horizontal offset adjacent to each other on the Rolltorpanzerwickelseite 20.

The damping body 34 are also designed such that the winding bale diameter d with the damping bodies 34 is minimal or not greater than a bale diameter d 'without the damping body 34. This can be achieved by a suitable height of the damping body 34 and / or their arrangement on the roller shutter be achieved.

The damping body 34 unfold by their elastic behavior a damping effect during the juxtaposition of the individual Rolltorstäbe 28, thus the noise and wear can be reduced. Existing roller doors can be easily retrofitted with the damping bodies 34.

For producing a roll-up door 10, a set of damping bodies 34 is fixed on the Rolltorpanzerwickelseite 20 on the Rolltorpanzerwickelseite 20 installed on the purpose built Rolltorpanzer 14, in particular glued, which is wound on winding the winding shaft 12 facing. In the present case, this is the inside of a building, for example a hall.
