The tension device being one of an inflatable cushion and a tension cable, with the tension device providing vertical tension to the bag.

Description

The invention relates to a method and a device for ironing clothes according to the preambles of claims 1 and 2.

Devices for ironing clothes are available in a variety of forms known in the art. A widespread, professional method of ironing clothes is ironing with a manikin. These temple dolls are made of a stand and an inflatable bag arranged above it. The inflatable bag can be impermeable to air and then only serves as a tensioning element for the garment to be dried, or the inflatable bag can also be designed to be permeable to air, in which case the air stream inflating the air bag dries the garment at the same time. In the last The inflatable bag in the neck area of the garment is often designed to be airtight is. If the inflatable bag is made impermeable to air, the Garment by means of a drying air stream applied from the outside. Partially these temple dolls also have inflatable sleeves. The clothes - Shirts, blouses, t-shirts and jackets in particular - are still wet pulled onto the inflatable sack of the temple manikin and then by means of fixing aids on the inflatable bag releasably attached. These fixing aids have the reason that on the one hand the garment is aligned as wrinkle-free as possible on the inflatable bag and that open areas of the Garment, such as the button strips are closed so that they are not buttoned Garments that dry air cannot escape. When ironing T-shirts the fixing aids are not absolutely necessary. Alignment only takes place here of the garment.

For example, the document US 3,568,900 is known from the prior art. On one A inflatable bag is arranged in the base area in the floor area. In the base frame is built in a floor construction that allows the air to flow into the inflation doll and also holds the inflatable bag at the same time. This device is for ironing shirts intended. The open shirt sleeves are closed with the help of a cuff clip and smoothed. The collar area is through a special use of the Inflatable bags are also closed and the button strips are made using a flat Pressed element sealed. Since shirts naturally have an opening at the bottom and be lifted upwards by the air flow emerging from the inflatable bag could be spring-loaded brackets on the ironed in this prior art To attach a shirt. These brackets fix the shirt by means of clamps the bottom shirt hem and are in turn with the floor construction of the temple manikin connected. This has the disadvantage that the operator with every single shirt attach these clips to the hem of the shirt and also with the finished ironed shirt must be removed again. This requires a considerable amount of time and is therefore more expensive the ironing costs.

The length of an inflatable bag is matched to the longest shirt. Therefore are the mentioned clips on the bottom hem of a shirt also from the Basically necessary, because with a shorter shirt, the inflatable bag is a manikin below the hem of the shirt inflates further than the size of the shirt, because the shirt limits the size of the inflatable bag. This bulge of the inflatable bag below the hem causes the shirt to rise up on the inflatable bag pushes. As a result, when ironing there are so-called - especially in the side seam area Ironing waves, also sometimes called washboard patterns.

A device according to the preamble of claim 1 is known from US 3,315,853 and from US 2,513,427.

It is therefore an object of the invention to find a manikin of the type mentioned at the beginning, which prevents or at least reduces the disadvantages mentioned.

According to the invention, this object is achieved by those mentioned in claim 1 Characteristics of the characteristic part solved. Advantageous configurations and Further developments of the invention result from the subclaims.

The inventors have recognized that those formed when ironing by means of a manikin Bead underneath a shirt (or blouse, t-shirt or jacket; only ever thereafter Called garment) by vertical stretching of the inflatable bag can. The inflatable bag is advantageously stretched vertically in the lower region of the inflatable bag, because this is where the bulge always arises. It also goes through tensioning no usable surface of the inflatable bag is lost in the lower area. By this vertical tensioning means that there is no longer any risk of clothing sliding up and thus the bow shafts are prevented. Because now the inflatable bag is pulled down and not the garment itself as in the prior art is pulled down, you save yourself when ironing every piece of clothing attaching and removing the clips on each garment. Thereby the process of ironing and changing the garment on the ironing manikin is clear shortened. Due to this vertical stretching of the inflatable bag, the area of the manikin, that is not covered by the garment, in the same shape as the inflatable bag below the garment.

In the temple manikin according to the invention, at least in the lower region of the inflatable bag a pulling device arranged. The pulling device is as an inflatable air cushion or designed and is as a pull rope with the floor construction of the temple manikin connected is. This has the advantage that the clamping forces are fixed in the shortest possible way Components of the temple manikin can be initiated. The floor construction can a simple stand or a complete supply unit in which the drying airflow is generated. This supply unit then also serves at the same time as a base / stand for the inflatable bag

It is particularly advantageous if the outer surface of the inflatable bag is preferred only in its lower area - equipped with a higher coefficient of friction than the rest of the surface. This lower area then extends from a little above the bottom hem of the shortest possible garment to the bottom End of the inflatable bag. The length of the inflatable bag is in turn determined by the length of the given the longest possible garment. Due to the higher coefficient of friction the fabric of the garment adheres better in this lower area. Now is that Place the garment on the inflatable bag, align it, activate the air flow and the Inflatable bag also stretched vertically, so the fabric of the garment also becomes vertical excited because the lower area of the inflatable bag takes this material with it. This allows no ironing waves occur when ironing.

It has been shown that only the lower quarter of the inflatable bag - based on its total length - Must be equipped with this higher coefficient of friction in order to be able to stretch the variety of clothing vertically.

It is also advantageous if this lower area with the higher coefficient of friction, is only applied selectively on the surface of the inflatable bag. This can you can specifically dimension the frictional force exciting the garment without unnecessary to drive areal effort for the higher friction coefficient. Moreover an unnecessary effort on these surfaces would result in a possibly desired air permeability of the inflatable bag unnecessarily.

This higher coefficient of friction can e.g. can be realized by using the rubberized outer surface of the inflatable bag. This rubber coating can be designed in this way be that they are either stored in the material of the inflatable bag or on the Surface is attached.

Another way to achieve a higher coefficient of friction is through the Apply a chemical adhesive. With this chemical adhesive the inflatable bag can already be equipped on the production side or can also be retrofitted Spraying - as required - can be realized.

The surface can also be used to achieve a higher coefficient of friction the inflatable bag with a structure that has a higher coefficient of friction having. This surface can be achieved by either using the material of the Inflatable bag inflated in a targeted and directed manner or by placing a material in particular Apply a strip shape to the surface of the inflatable bag, which has a higher coefficient of friction has, such as rubberized fabric tapes or Velcro.

All of these measures to increase the coefficient of friction can be taken individually, i.e. exclusively or can also be used in combination.

One design of the mechanical pulling device is its constructive implementation as pneumatic active element. If an inflatable air cushion is used, it can only generate forces - namely compressive forces - when inflated.

A special one is required to convert these forces into tensile forces Arrangement. For example, is the inflatable bag at its lower end, so to speak "flanged" on the inside and here lies on a support of the floor construction, see above can with an air cushion between this pad and the flanged area tension is built up by inflating the air cushion.

The inflatable air cushion can be designed in a ring shape. Another configuration the pneumatic pulling device can also be implemented constructively, by arranging several air cushions in a ring in the area of the floor construction.

The inflatable bag can also be stretched vertically using a pull rope. For this again the lower edge of the inflatable bag must be flanged inwards. A pull rope, which is star-shaped between the eyelets of the lower end of the inflatable bag and eyelets the floor structure is arranged, a vertical tension when actuated of the inflatable bag.

Another possibility is to tension the inflatable bag using a pull rope, if the inflatable bag is below its area of use as a support element over a waist features. If a traction rope is now wrapped around this waist and this is operated, you can in turn vertical clamping forces are generated.

So that the inflatable bag is not tapered downwards when tensioned, it is advantageous when the inner surface of the inflatable bag can be supported in the lower area. There it is constructive in the lower area of the inflatable bag advantageous if this support is carried out on an outer edge of the floor structure. So that no damage to the inflatable bag or even its fraying is not possible are, it is advantageous if this outer edge of the floor structure with a radius is provided.

The aforementioned constructive measures are very advantageous overall because they are a vertical stretching of the inflatable bag with a short stretch, in particular less than Enable 20 millimeters. As a result, the mechanical outlay is low and therefore inexpensive.

The invention will now be explained in more detail with reference to the figures. Show it

In Figure 1, a lower section of a temple doll 3 can be seen. In addition, this is lower section has also only been shown half, which is illustrated by a center line 17 becomes. Lines 16 symbolize demolition lines. A garment 1 is loose on an inflatable bag 2. The inflatable bag 2 rests on a floor structure 6 which that forms under the end of the manikin 3. The inflatable bag 2 has a lower region 8 a surface with a higher coefficient of friction 10 than the upper region 9 of the Inflatable bag 2. These surfaces 10 are only for reasons of better visibility and also drawn in this exaggeration on the surface of the inflatable bag 2. An air stream that tightens the inflatable bag 2 is already active, because you can get one See bulge of the inflatable bag 2 below the lower hem of the garment 1. The garment 1 is still wrinkled on the inflatable bag. An air cushion 11, which arranged between parts of the inflatable bag 2 and a support of the floor structure 6 is not yet inflated. This air cushion 11 represents a pulling device 7 represents with which the inflatable bag 2 can be stretched vertically downwards. So now there are no ironing waves on the garment 1, the inflatable bag 2 must be stretched downwards, i.e. the air cushion 11 must be inflated. The surface of the inflatable bag 2 with their surfaces with a higher coefficient of friction 10 then take the lower end the garment 1 with and also tension it. This causes the wrinkles to disappear out of the garment and the airflow creates a smooth surface of the Garment 1. In Figure 1 you can clearly see that the areas with higher Friction coefficients 10 cover a wider area than it does for the current one Garment 1 would be required.

In Figure 2, the air cushion 11 is now in the inflated state. For the sake of uniformity and the better overview, apply to Figure 2 and all other figures, the reference numerals continue with the same meaning. A not covered by the garment 1 Area 4 has the same shape due to the vertical stretching of the inflatable bag 2 assumed that the area 5 of the inflatable bag 2 covered by the garment 1 Bead shown in Figure 1 can no longer be determined. That the inflatable bag is actually excited was, u can see here that compared to Figure 1 now surfaces with higher coefficient of friction 10, below the upper contact surface of the air cushion 11 are located. So that the air cushion 11 can function as a pulling device 7, it is necessary that the inflatable bag 2 is fixed to the floor structure 6. The one shown here There is actually no spacing between the garment 1 and the inflatable bag 2, but only results because the surfaces with a higher coefficient of friction 10 - like to Figure 1 already executed - were exaggerated in their thickness.

3 shows a further embodiment of the pulling device 7. On Traction rope 12 is by eyelets at the lower end of the inflatable bag 2 and by eyelets at the Floor construction 6 pulled through. If the pull rope 12 is now tensioned, it will also the inflatable bag is stretched vertically. The pull rope 12 can then, for example, by means of a Clamp are held in the cocked position. So that the inner surface 13 the inflatable bag 2 when it is deflected around an outer edge 14 of the floor construction 6 cannot be damaged, this outer edge 14 has a circumferential radius 15 provided.

In the embodiment of Figure 4, another application of the Towing ropes are illustrated when the inflatable bag is stretched vertically. The floor construction 6 here has a circumferential waist, in which both the lower end the inflatable bag 2, as well as the traction rope 12. The inflatable bag is below the waist 2 attached to the floor structure. If the pull rope 12 is now tensioned, the Inflatable bag 2 constricted and therefore tense. This tension then takes place again the vertical tension of the inflatable bag 2.
