Description

Device for smoothing a garment

The present invention relates to a device for smoothing a garment, in particular a garment for the upper body, such as a shirt, blouse or jacket.

It is known to dry or smooth items of clothing by pulling them onto an inflatable body, which is also referred to as an inflatable manikin and which essentially has the shape of the item of clothing to be smoothed, and supplying these inflatable bodies with air or steam from the inside. The inflatable body is inflated by the air or steam supply and tensions the ironing or drying material from the inside. In order to achieve a uniform inflation of the inflatable body and thus a good drying and smoothing result, it is necessary to distribute the air or steam introduced into the interior of the inflatable body so that the inflatable body assumes the desired shape.

For this purpose, a device is proposed in US Pat. No. 3,165,244, in which an inflatable body is used which is divided into several chambers. The individual chambers are formed by partitions provided in the inflatable body, which can represent diaphragms, for example. These chambers are inflated by a fan via separate lines, the air supply in one chamber being able to be throttled in favor of the air supply in the other chambers. This structure is very complex due to the lines to be provided and the necessary regulation.

Furthermore, it has been proposed in DE 100 63 672 A1 to create a device for smoothing shirts, which has a divided inflatable body. An outer inflatable body and two inner inflatable bodies arranged therein are provided. The inner inflatable body consist of air-permeable material and each have a fuselage section and a sleeve section. The pressure in the outer inflatable body is generated by the air emerging from the inner inflatable bodies, wherein openings can additionally be provided at the ends of the sleeve sections in order to allow a higher air supply to the sleeves of the outer inflatable body. The air that exits through the sleeve sections is also used to supply air to the torso section. If the air flow is interrupted from the sleeve section to the trunk section, this section will collapse due to the lack of air supply in the trunk section, which leads to a poor smoothing result in this area. Such an interruption in the air supply from the sleeve section to the torso section can occur, for example, when a garment of smaller dimensions is pulled onto the outer inflatable body.

The invention is therefore based on the object that a device for smoothing is to be created, in which a uniform inflation of the outer inflatable body can be ensured in a simple manner.

The invention is therefore achieved according to the invention by a device for smoothing clothes, in particular shirts, the device comprising an outer inflatable inflatable body with a torso section and two sleeve sections which are connected laterally to the torso section, and an inner inflatable inflatable body which essentially consists of one air-impermeable material. The air supply in the device according to the invention is such that the air supply for the sleeve sections and for the torso section of the outer inflatable body takes place separately via the inner inflatable body.

A separate air supply to different sections of the outer inflatable body is understood to mean that the air for one section does not have to pass through the other section. The inner inflatable body in the device therefore fulfills the function of supporting the shape of the outer inflatable body and at the same time the function of supplying air to the separate areas. Thus, the entire structure of the device is kept simple. In the inflated state of the device, in which it smoothes the garment, which is preferably damp, on it, the air supply takes place exclusively separately, while in the initial stage of the smoothing process there can still be some air exchange between the body section and the sleeve sections. The separation between the body section and the sleeve sections in the outer inflatable body is preferably formed in part by the casing of the inner inflatable body. The provision of separate partition walls or diaphragms between these areas can thus be omitted. In addition, this configuration enables the outer inflatable body to be supported at the dividing line between the sleeve section and the trunk section, ie at the sleeve opening of the trunk section.

The inner inflatable body preferably has a body part and two arm stumps connected to it laterally. Here, the separation between the torso section and the sleeve sections in the outer inflatable body is formed by part of the sleeve stumps. Since the separation takes place due to the abutment of the inner inflatable body against the outer inflatable body, the sleeve stump of the inner inflatable body is preferably designed such that the circumference of the sleeve stump is larger than the circumference of the sleeve section of the outer inflatable body. In this way, a reliable separation of the sleeve section and the torso section can be achieved. On the other hand, the difference in the diameters can be used in order to achieve a firm abutment of the sleeve stump on the sleeve section and thus a good smoothing of the sleeve of the garment in this area.

The separation thus only occurs in the inflated state of the inner and outer inflatable bodies, while the inner and outer inflatable bodies are not connected to one another in the relaxed state. This has the advantage that the inflatable bodies are removed individually from the device and can be cleaned, for example.

The length of the sleeve stumps preferably corresponds to at least a quarter or a third, particularly preferably half, of the length of the sleeve section of the outer inflatable body. This sleeve stump thus lies against the upper part of the sleeve section of the outer inflatable body. This in turn is surrounded from the outside by the sleeve of the garment or shirt. Air with an increased pressure must be introduced into the sleeve section of the outer inflatable body, for example in order to achieve a sufficient stretching of the sleeve section in the area of the sleeve attachment and thereby prevent fold-in points. In addition, the drying of the seams on the Garment to be guaranteed in the sleeve neck area. If the air is directed into the entire sleeve area of the outer inflatable body with increased pressure, this occurs particularly in areas in which only one layer of fabric is provided, e.g. in the upper sleeve area, for a quick drying and then for a loss of the heated air over this area, which represents a loss of energy. The sleeve stump thus serves to slow down the drying of the upper sleeve area of the garment and still be able to ensure the application of sufficient pressure in this area. Since the material of the inner inflatable body and the material of the outer inflatable body lie one above the other in the upper region of the sleeve section, the escape of air is slowed down and the drying in the upper sleeve region is slowed down and adapted to the remaining outer inflatable body. At the same time, the pressure required to unfold the sleeve in the sleeve attachment area and to dry the seams in this area is generated via the sleeve stump.

A wedge can be provided on the inner inflatable body at the arm stump opening, which generates a larger circumference of the sleeve stump near the arm stump opening than at the arm stump opening. This wedge, which is made of the same material as the inner inflatable body, makes it easy to enlarge the circumference of the sleeve stump at a short distance from the sleeve stump opening. This prevents warping in this area and also supports a wedge provided on the outer inflatable body, which serves to enlarge the circumference of the sleeve section, in such a way that the sleeve section lies sufficiently against the garment.

The sleeve section of the outer inflatable body can be ventilated via the end faces of the sleeve stumps, which are designed to be air-permeable for this purpose. The air permeability can be achieved by a suitable choice of the material, for example an open textile material, or by the provision of one or more openings in a dense material. For example, an opening of 24 mm in diameter can be made on the front side in a dense material. This ideally directs the air flow. The air supply for the fuselage section of the outer inflatable body can be realized through air-permeable areas in the fuselage part of the inner inflatable body. Here, too, the air permeability can be achieved by a suitable choice of material, for example an open textile material, or by providing one or more openings in a dense material.

The inner inflatable body is preferably formed from two separate side parts, each of which forms part of the trunk part of the inner inflatable body. The side parts preferably each have a sleeve stump which projects into the sleeve section of the outer inflatable body. Due to the stability that the side parts have in the inflated state, an existing distance between the side parts is also during the smoothing process, i. H. after stretching a garment. In addition, the inside of the side parts can be supported by a frame which can be formed, for example, by bars or by continuous surfaces. Compression of the two side parts is thus avoided even when stretching a smaller size garment. In one embodiment, connecting means are provided between the side parts, which can be strips of fabric, for example. This prevents the side parts from moving apart.

In a preferred embodiment, the side part of the inner inflatable body is at least partially air-permeable on the side which faces the further side part of the inner inflatable body. The air permeability can also be achieved here by a suitable choice of material, for example an open textile material, or by providing one or more openings in a dense material. For example, four openings of 24 mm in diameter can be made on the side of the side part which faces the further side part. As a result, a sufficient, regulated air supply to the torso section of the outer inflatable body can also be achieved when a garment of smaller size is pulled onto the device. In particular if the side parts are held by a frame, the distance between the inner sides of the side parts is always unchanged and the air supply to the fuselage section of the outer inflatable body is always guaranteed. In the device, a pressure ratio between the outer and the inner inflatable body is preferably set from 1: 2.5 to 1: 4.5, preferably from 1: 3 to 1: 3.5. This pressure ratio exists both in the sleeve section and in the torso area. This pressure ratio is achieved by the essentially airtight design of the inner inflatable body. The exact setting of the pressure difference can also be done by choosing the size of the air-permeable areas on the arm stumps and the torso part of the inner inflatable body.

Areas which have an air permeability in the range from 0 to 3 L / m ² s, preferably from 0 to 1 L / m ^z s, are preferably referred to as air-impermeable areas of the inflatable bodies. Areas of medium air permeability preferably have an air permeability in the range from 3 to 20 L / m ² s, preferably from 5 to 10 L / m ² s. The air-permeable areas preferably have an air permeability in the range from 100 to 250 L / m ² s, preferably from 150 to 210 L / m ² s. The values are preferably measured at a differential pressure of 100 Pa.

The invention is described in more detail below with reference to the accompanying figures. Show it:

Figure 1 is a schematic perspective view of an embodiment of the device according to the invention; and

Figure 2: a detailed view of a side part of an inner inflatable body of the

Embodiment of the device according to the invention according to FIG. 1.

FIG. 1 shows a device 1 which consists of an outer inflatable body 2 and an inner inflatable body 3. The outer inflatable body 2 is only partially indicated in order to allow a view of the inner inflatable body 3. The outer inflatable body 2 comprises a trunk section 21 and two sleeve sections 22, which are connected laterally to the trunk section 21 via a sleeve opening 23. An inner inflatable body 3 is accommodated in the outer inflatable body 2. In the embodiment shown, the inner inflatable body 3 is formed by two side parts 31 and 32. A side part 31 of the inner inflatable body 3 is shown in more detail in FIG. The construction and the mode of operation of the device according to the invention is explained below in particular with reference to this side part 31, which is shown in FIG. 1 as the left side part. The other side part 32 on the right in FIG. 1 has the same structure and fulfills the same functions.

The side part 31 has a body part 311, the body parts of the first and second side parts 31 and 32 are spaced apart and together form the body part of the inner inflatable body 3.

On the side part 31, a sleeve stump 312 is arranged laterally. This is connected to the side part 31 via an arm stump opening. An opening 314 is provided on the end face 313 of the sleeve stump 312. The circumference of the sleeve stump 312 is essentially formed by a cut part of a material, preferably a textile material. A wedge 315 is provided on the lower side of the sleeve stump 312 and serves to enlarge the circumference of the sleeve stump. The wedge 315 is preferably made of the same material as the peripheral surface of the sleeve stump 312. In the illustrated embodiment, a corresponding wedge is incorporated on the sleeve section 22 of the outer inflatable body 2 on the underside of the sleeve opening.

The body part 311 of the side part 31 of the inner inflatable body 3 is formed on the side facing the further side part 32 by an inner side 4. On this inner side 4 of the fuselage part 311, in the embodiment shown, a cut part 41 is incorporated at a medium height, which has a high air permeability. The other cut parts 42 and 43 of the inside 4 of the side part 31 are preferably designed to be tight. A connection opening 44 is provided in the lower cut part 43 of the inside 4, via which the side part 31 can be connected to a fan of a housing (not shown) provided below the inflatable body 2. With the device 1, which is shown in Figures 1 and 2, a piece of clothing, in particular a shirt, can be smoothed in a simple and reliable manner. The garment is stretched over the outer inflatable body 2. Here, the sleeve sections 22 of the outer inflatable body 2 are inserted into the sleeves of the garment and these are preferably fastened there. Subsequently, air and steam are introduced into the inner inflatable body 3 via a fan, preferably via the connection opening 44. In the illustrated embodiment, air is introduced into both side parts 31 and 32 in this way. The inner inflatable body 3 inflates, the stumps of the side parts 31 and 32 also being inflated.

Via the opening 313 in the sleeve stump 312 and the corresponding opening in the sleeve stump of the side part 32, the air is conducted from the inner inflatable body into the sleeve section 22 of the outer inflatable body 2, whereby this inflates as well. Due to the larger circumference that the sleeve stump 312 has compared to the circumference of the sleeve section 22, the outside of the circumference of the sleeve stump 312 is pressed against the inside of the circumference of the sleeve section 22. This prevents the air supply from the opening 314 in the end face 313 to the fuselage section 21 of the outer inflatable body 2.

According to the invention, the trunk section 21 of the outer inflatable body 2 is supplied separately from the air supply to the sleeve sections 22. In the embodiment shown, the air supply is achieved through an area 41 on the inside 4 of the side parts 31 and 32 of the inner inflatable body 3. The area 41 is designed to be permeable to air, so that the air introduced into the inner inflatable body 3 can reach the fuselage section 21 of the outer inflatable body 2 via this area.

The air supply to the sleeve sections 22 thus takes place in the inflated state of the inflatable bodies 2 and 3 of the device 1 exclusively via the sleeve stumps of the side parts 31 and 32, in particular via openings 314 provided in the end face of the sleeve stumps. The air supply for the trunk area 21 of the outer inflatable body 2 takes place in the illustrated embodiment exclusively via the air-permeable areas 41 on the inner sides 4 of the side parts 31 and 32 of the inner inflatable body 3. In the illustrated embodiment, the end face 313, the cut part of the sleeve stump 312, the wedge 315, and the cut parts which form the body part 311, except for the inside 4, are made of a material which has an air permeability in the range from 0 to 1 L m ² s measured at a differential pressure of 10OPa, ie is essentially tight. The cut parts 42 in the upper region and 43 in the lower region of the inside are preferably also formed by this dense material. In contrast, the air-permeable area 44 preferably has an air permeability in the range from 150 to 210 L / m ² s. The values are measured at a differential pressure of 100Pa. It is also possible to incorporate a further cut part on the fuselage part 311, for example on the side opposite the inner side 4, which has an average air permeability in the range from 3 to 20 L / m ² s, preferably in the range from 5 to 10L / m ² s, measured at a differential pressure of 100 Pa. This cut part can extend over the body part from the lower edge to the arm stump opening and serve to dry the side seam of the garment in the body area.

The cut part which forms the sleeve section 22 of the outer inflatable body preferably has an air permeability in the range from 0 to 1 L / m ^z s, measured at a differential pressure of 100 Pa, that is to say is essentially tight. At the lower area of the sleeve section, areas with medium air permeability and open areas can be provided for drying the cuff and the cuff slit.

With a device according to the invention, pressure values can be achieved in the individual areas of the inflatable bodies, which can have the following values, for example. Air or steam can be introduced at a pressure of 400 Pa via the connection opening. As a result, a pressure of, for example, 350 Pa can be established in the sleeve sections 22 of the outer inflatable body 2, which enables an excellent smoothing result on the sleeve of the garment. A pressure of 100 to 120 Pa can be established in the fuselage section 21 of the outer inflatable body 2, in particular between the two side parts 31, 32 of the inner inflatable body 3. These pressure ratios are ideal for smoothing a garment with the device according to the invention. The present invention is not limited to the illustrated embodiment.

Although in the embodiment shown the air-permeable region 41 extends only over the central region of the inside 4 of the side part 31 of the inner inflatable body 3, it is also possible according to the invention to make the entire surface of the inside 4 of the side part permeable to air. The pressure ratio between the outer and the inner inflatable body, in particular in the fuselage section of the outer inflatable body, can be adjusted via the size of the air-permeable area.

The opening on the face of the sleeve stumps is also not limited to a certain size. Furthermore, it is possible, instead of an opening on a tight cut part on the end face of the sleeve stump, the entire end face of the sleeve stump made of an open material, for. B. to form a textile material.

The inner inflatable body thus serves for air distribution in the outer inflatable body and as a shaping element for the latter. The shaping of the outer inflatable body is possible because there is a pressure difference between the outer and the inner inflatable body in favor of the inner inflatable body. This means that the pressure in the inner inflatable body is greater than the pressure in the outer inflatable body. This pressure difference is due to the fact that the outer inflatable body is not supplied with air directly but only indirectly via the inner inflatable body. According to the invention, this air supply to the torso section and the sleeve sections is implemented separately. For this purpose, air supply means in the form of air-permeable material and / or dense material with openings are provided on the arm stumps and the body part.
