Definitions
- the invention relates to a rollable protective film made of plastic for glazing, the protective film a variety of about arranged parallel to the roll axis, over the entire width of the film extending, formed by permanently pre-formed folds Has stiffeners, the folds by a a pleating process comprising a pre-folding step Protective film are formed and the protective film alternately at an obtuse angle to each other and in the area there is a fold of adjacent film sections, and each section of film through a flat surface is formed.
- a rollable protective film as a film roller blind Protection against sun, heat, UV rays and as a privacy screen for windows, shop windows, glass partitions, glass doors, conservatory glazing, etc. to use.
- Such protective films have a flat and smooth surface structure and can if necessary, be metal-coated.
- a protective film can be made from each several layers with different properties exist, making protection individual for each Use case can be coordinated.
- Such film blinds can, for example, as daylight filters against UV rays and glare can be used. Protection is no longer necessary or desired, the original can be rolled up Condition can be restored without restriction. To enable the film to roll well, the Protective film is relatively thin.
- DE-A-30 45 883 describes one as an outer curtain a window blind made of metal or plastic, with a protective film of the type mentioned which on a profiled winding shaft can be rolled up, the profiling is formed by teeth.
- the film has one of the profiles customized zigzag folding to form interconnected folds that appear at intervals with different, Width dimensions increasing from top to bottom are trained.
- the blind points in areas with larger gaps between the folds a smaller one Stiffness.
- the different distances increase above addition, the manufacturing effort.
- the profiled winding shaft conditionally also relatively large folding angles, which on the one hand makes the Visibility is severely restricted and on the other hand infrared rays are reflected insufficiently.
- the profiled Winding shaft and the large folding angle require a relative high space requirement.
- From BE-A-883 661 is a device for thermal insulation known with a rollable film, which used to stiffen each other spaced folds. Every fold is there as a V-shaped, recessed furrow of shallow depth trained and is made by rolling cogs of suitable Cross-section created across the film. The stiffening effect through the furrows and thus protection against bowls and dents is, however, less than for wrinkles caused by a a pleating process comprising a pre-folding step will.
- a roller shutter for furniture is known from EP-A-0 019 140, the one made of a rollable laminate with the back Cross stiffeners arranged transversely to the winding direction consists.
- the cross stiffeners are embossed in Form formed by grooves, ribs or beads film.
- Such a Roller shutters with stiff embossing have the disadvantage of a high one Requires space when rolled up, which is why it is for larger Areas such as glazing are only suitable to a limited extent.
- a not rollable from a pleated film existing film blind known.
- a pleated film existing film blind known.
- the distance between the folds is determined by the space required determined and in the folded state of the film blind at least about 2.5 cm.
- Such a folding blind has several Disadvantage.
- the material stress is caused by the constant folding and unfolding higher than with a roller blind.
- the distance between the individual folds is too large to form an effective stiffening against buckling of the film can. A reduction in the distances would be negative on the foldability and on the space required in the folded Condition.
- the object of the invention is to avoid these disadvantages and a rollable protective film that is insensitive to bowls or dents to accomplish.
- this is achieved in that the folds of the preferably protective film consisting of several film layers are evenly spaced from each other, and that the between one film section and one through the adjacent one Plane section extending plane measured folding angle both in the unrolled as well as in the rolled state under 30 °, preferably about 15 °.
- This creates the section modulus the film increased normal to the stiffeners while continuing unrestricted rolling up and unrolling of the protective film is possible.
- the relatively small fold angles allow one high specific reflection of infrared rays and also have the advantage that the protective film, both when unrolled, and also requires little space when rolled up.
- Pleating the protective film makes it particularly easy Production of stiffeners enables. In contrast to Folded blinds are only pre-folded when pleating the Protective film. However, while the protective film is in use no more folding.
- the protective film consists at least predominantly of polyester. See-through roller blinds made of polyester material too Manufacturing is known for example from DE 36 02 954 A1. When pleating the polyester film, there is a plastic one Shape change in the molecular area, which during the entire The lifespan of the protective film is preserved.
- the distance between two neighboring ones Stiffeners between 5 mm and 20 mm preferably is between 7 mm and 14 mm. If the distance is greater, the necessary stiffening of the film is insufficient, and the ability to roll is deteriorated, at a smaller distance the light transmission becomes the film is reduced too much.
- the protective film 1 can be rolled up or unrolled around the roll axis 1 ' attached.
- the protective film 1 points at regular intervals folds 3 formed by pleating, which stiffeners 2 Form over the entire width B of the protective film 1.
- the approximately Stiffeners aligned parallel to the roll axis 1 'of the roll 4 2 are each at a distance b between 5 and 20 mm, preferably in a range between 7 and 14 mm apart. Distances greater than the specified deteriorate the rollability of the protective film 1, shorter distances have a negative effect on the appearance and reflection the protective film 1.
- the resulting from the pre-folding Folding angles ⁇ between two neighboring folds 3 Foil sections 1a and 1b improve the specific Reflection of infrared rays.
- the folding angles ⁇ are below 30 °, mostly about 15 °, which on the one hand makes it easy to roll and on the other hand there is sufficient stiffening.
- the protective film 1 is a final rod 5 on this attached, which the protective film 1 by its own weight stabilized.
- the protective film 1 can consist of several film layers and also be metal-coated, which makes the wavelength individual the transmitted and reflected radiation both set in the visible as well as in the non-visible area can be.
- the thickness of the protective film 1 can be about 0.02 mm for one film layer up to about 0.6 mm with several film layers be.
