Definitions
- the invention relates to a method for replacing the fabric of an awning. It also relates to an arrangement for performing such a method.
- Awnings have a winding shaft on which the awning cover can be wound up when it is not needed.
- the winding shaft has an elongated opening, usually the opening of a longitudinal groove provided in the winding shaft.
- a so-called piping is inserted into this, typically a plastic tube that has a diameter in the range of approximately 4 to 6.5 mm, or another suitable plastic profile. The hem with the inserted piping is pushed into the longitudinal groove of the winding shaft, and in this way the awning fabric is captively attached to the winding shaft and secured against tension.
- the awning cover If after some time of use the awning cover has become bad due to environmental influences or mechanical damage, it must be replaced. To do this, remove the winding shaft according to current practice, slide the piping and the hem of the old awning fabric out of the longitudinal groove, insert the piping into the hem of a new awning fabric, push the new awning fabric and piping back into the longitudinal groove, and then reinstall the winding shaft.
- ERSATZBL ⁇ TT (REGEL26)
- the object of the invention is to provide a new method for replacing the fabric of an awning, and a new awning arrangement.
- this object is achieved by a method for replacing the fabric of an awning, a textile blind, a textile covering or the like - hereinafter called the awning fabric - with the following steps: a) the old awning fabric is removed;
- the invention is advantageously further developed so that in step a) the piping is left in the longitudinal groove of the winding shaft. This makes it unnecessary to remove the winding shaft in order to be able to remove the piping from it.
- step b) a hook provided on the magnetic tape is hooked into an edge of the longitudinal groove of the winding shaft. This creates an additional connection to the winding shaft that can withstand tensile loads.
- awning cloth - with a winding shaft which has an opening for fastening one end of the awning cloth is provided with a flexible magnetic tape fastened in the area of this cloth end for magnetic adhesion to the winding shaft, and with a hook provided on the cloth end for hanging into the opening of the winding shaft.
- the magnetic tape which is attached to the end area of the awning fabric, "sticks" this end area of the awning fabric to the winding shaft, because it regularly consists of a galvanized or painted steel tube, to which a magnet adheres very well. This prevents unwanted shifting of the awning fabric in the axial direction, but allows the awning fabric to be displaced in the tangential direction when the awning fabric is stretched.
- the opening of the winding shaft is designed as an opening in a groove and the hook is designed in such a way that it does not hinder the remaining piping in this groove of the winding shaft. This makes it possible to leave an existing piping in place and to avoid having to remove the winding shaft when changing the awning fabric.
- a very secure attachment results in an arrangement in which the flexible magnetic tape is attached to the side of the awning fabric facing the winding shaft.
- the magnetic air gap between the flexible magnetic tape and the winding shaft is very small and the magnetic holding force is particularly large.
- Adhesive connection the stitch spacing of such a seam is preferably about 4 to 6 mm, which is a safe and permanent connection between the awning fabric and the flexible magnetic tape without undesirably weakening the latter by the sewing process.
- a very simple embodiment results in an arrangement according to the invention in which the flexible magnetic tape and the hook are formed in one piece with one another.
- the magnetic tape and hook can be processed by the same process, e.g. be attached to the awning fabric by one or two seams.
- the flexible magnetic tape and the hook are jointly formed in the form of a profile made of an elastomer, to which elastomer a magnetic material, in particular a hard ferrite powder, is added.
- the elastomer can be rubber, a plastic, or a mixture of the two.
- Such flexible magnets are therefore also referred to as rubber magnets.
- a particularly large holding force on the winding shaft is obtained if the flexible magnetic tape is magnetized in such a way that north poles and south poles are arranged alternately on its side facing the winding shaft in the assembled state.
- a favorable form of the hook which is used for hanging in the opening of the winding shaft, is characterized in that, when stretched and seen in cross section, this hook is designed in the manner of an acute angle.
- FIG. 1 is a plan view of the end of a winding shaft to which an awning fabric is attached in the manner according to the invention, according to a first embodiment of the invention
- FIG. 2 is a plan view of the arrangement of FIG. 1, seen in the direction of arrow II of FIG. 1,
- FIG. 4 shows an illustration of one end of the awning fabric with hooks, in the straight state, that is to say before it is attached to a winding shaft
- FIG. 7 is a plan view, seen in the direction of arrow VII of FIG. 6,
- Fig. 9 is a plan view, seen in the direction of the arrow
- FIG. 10 is a side view of the magnetic tape of Fig. 9 including a schematic representation of its magnetization.
- Fig. 1 shows a plan view of one end of a winding shaft
- Shading e.g. also the cloth of a blind or the like.
- the piping 14 can be, for example, a plastic tube with a diameter of 6 mm, but can also have any other shape that makes it in the
- a flexible magnetic tape 18 is sewn onto the end section 15 of the awning fabric 12 on the winding shaft side and on the side facing the winding shaft 10 by means of two seams 19 and 20, the course of which is clearly shown in FIG. 2 .
- These seams have a stitch spacing on the majority of their longitudinal extent, which is 5 mm or more and is typically about 8 mm in size. This enables attachment to the flexible magnetic tape 18 without destroying it or weakening it too much due to the repeated perforation with the sewing needle. Alternatively, e.g. an adhesive connection possible.
- the magnetic tape 18 is made by extrusion molding a mixture of an elastomer and a hard ferrite powder, and this mixture is magnetized after production so that e.g. A north pole is formed on the underside of FIG. 4 and a south pole is formed on the upper side, as indicated there by the letters N and S.
- the magnetic tape 18 is provided with a hook profile 22 for hanging in an edge of the opening 16.
- This hook profile 22 is designed so that it leaves enough space in the groove 11 for the welt 14 remaining there, so that it does not need to be removed.
- the opening angle alpha of the hook profile 22 is an acute angle of, for example, 80 °. After assembly according to FIG. 3 if this angle decreases somewhat due to the curvature of the magnetic tape, it becomes a little more pointed.
- the hook 22 is designed so that it can be easily hooked into the various customary groove shapes of such winding shafts and does not hinder the respective piping 14.
- the rounded shape 23 of its right end in FIGS. 3 and 4 has proven to be very advantageous for this purpose. 3 and 4 show a preferred cross-sectional profile of this hook 22.
- step 30 of the flow chart of FIG. 5 the old awning fabric (not shown) is first removed from the winding shaft 10 by slitting it on its hem and pulling it radially out of the opening 16.
- the piping 14 remains as a - now non-functional part in the longitudinal groove 11 of the winding shaft 10.
- step 31 the prepared new awning fabric 12 with its flexible magnetic tape 18 is placed in the correct position on the winding shaft 10 so that the hook profile 22 engages in the opening 16.
- the magnetic tape 18 makes it very easy to align the awning fabric 12 on the winding shaft 10, since it can be moved relatively easily in the radial direction, but not in the axial direction. By lifting off the winding shaft 10, however, it can also be moved in the axial direction if necessary.
- step 32 the new awning fabric 12 is then wound up under tension.
- the hook profile 22 pulls into the groove 11 and hooks into the left edge of the recess 16 in FIG. 3.
- 6 to 8 show a second embodiment of the invention.
- the same or equivalent parts as in FIGS. 1 to 4 are denoted by the same reference numerals as there and usually not described again. This applies, for example, to the winding shaft 10, its groove 11, and the piping 14 located there.
- FIG. 8 which is enlarged approximately on a scale of 5: 1, shows a flexible magnetic tape 38, which is magnetized homopolar in the same way as that shown in FIG. 4, and its production with that described for the magnetic tape 18 Manufacturing coincides.
- the magnetic tape 38 is provided with a barb 42 for hanging in an edge 41 of the slot opening 16.
- the hook opening 43 is better at the cross-sectional shape of the edge
- the awning 12 is sewn on only in the area of the left free end of the magnetic tape 38 (single seam 39) and extends only over about a third of the magnetic tape 38.
- the magnetic tape 18 or 38 is already produced curved (e.g. by extrusion) during its manufacture, for example in the manner shown in FIG. 8, the curvature being selected such that it is adapted to the curvature of conventional winding shafts 10.
- the preferred stitch width of the seam 39 is also in the range from 4 to 6 mm.
- the method of operation corresponds to that of the first exemplary embodiment and is therefore not described again.
- FIG. 9 and 10 show a further exemplary embodiment with a magnetization pattern for the magnetic tape 38 which differs from FIG. 4.
- the latter is magnetized heteropolarly on its side 49 facing the winding shaft 10 (FIG. 8), i.e. elongated strips 48 with north poles alternate with elongated strips 50 with south poles.
- FIG. 10 also shows the course of the magnetic field lines 52 on the side 49 of the magnetic tape 38 in a schematic manner.
- the mode of operation corresponds to that of the first exemplary embodiment and is therefore not described again.
