Abstract

An ironing shoe which can be used under an iron sole and which has an ironing surface which can be brought into contact with ironing, and which has a base body and further comprises a fastening element for fastening the ironing shoe to an iron, wherein the ironing surface is a textile material has for direct contact with the ironing

Description

  • The invention relates to an iron shoe, which has a base body and an ironing surface, which can be brought into contact with ironing material. The ironing shoe can be used with all common irons, especially with electric irons and electric steam irons. It can also be used with irons that are connected to a separate steam ironing station. The ironing shoe has a fastener, with which it can be attached to an iron, and can also be removed again. The respective iron is then suitable for ironing without the shoe. The invention also relates to an iron that can be used with such an ironing shoe and a method for ironing, in which the ironing shoe is used.
  • The US Pat. No. 3,905,138 discloses an iron shoe. This ironing shoe has a laminated sole structure consisting of an impermeable layer of aluminum, copper, sheet metal or other non-ferrous metal of an intermediate layer of nomexnylon fabric impregnated with FEP teflon and a sole base layer with TFE teflon. The middle layer of Nomexnylon fabric with FEP Teflon has water repellent properties.
  • Another iron shoe is also the EP 1 031 655 (Rebordosa et al. ) known. This ironing shoe comprises a sole base body, which may be formed of aluminum, the underside of which serves for ironing on the ironing material and on whose upper side an insert is arranged, which has a capillary layer of moisture-absorbing material.
  • It is an object of the present invention to provide an ironing shoe and an electric steam iron with a detachable ironing shoe of the type mentioned, which has optimal performance characteristics.
  • This object is achieved by an ironing shoe with the features of claim 1, and by an iron according to claim 13 and a method for ironing according to claim 14.
  • In this patent application "bottom" is used for that side of the ironing shoe or possibly also the iron, which should come into contact with the ironing material or at least directed to the ironing material. The "top" of the ironing shoe is accordingly the opposite side, which should come into contact with a soleplate with the soleplate or at least on the sole out is oriented.
  • It is therefore proposed to provide a strap shoe available in which the ironing surface has a textile material for direct contact with the ironing material. The use of a textile material on the ironing surface allows a good vapor permeability to the ironing. The ironing shoe can therefore be used very well with a steam iron. Furthermore, the textile material allows reliable drying of the vapor by filtering out small water droplets. But even when ironing without steam, a textile sole has many advantages. The sole has a low heat storage capacity, so that it has a low starting temperature when putting the shoe on the iron even after repeated use. This makes it efficient for temperature reduction.
  • An ironing shoe is often used to iron certain delicate areas of a garment during ironing particularly gently or to iron a single item of clothing particularly gently when ironing several garments in a row. Such gentle ironing can avoid shiny spots. It would be conceivable usually the up and down rules of the ironing temperature, as most irons allow this. Irons, however, which have a heavy metallic sole, have so much heat capacity in this sole that cooling of the sole takes a long time. The use of an ironing shoe, however, leads to an immediately ready-to-use iron with greatly reduced working temperature at the sole.
  • Furthermore, the use of a bar shoe also allows the ironing temperature to be chosen independently of the sole temperature. This is advantageous in a steam iron, since in conventional steam iron a high sole temperature leads to high steam generation. Thus, a steam iron can provide a low working temperature and a high steam outlet with a high sole temperature and good steam outlet in combination with an iron shoe.
  • In this context, it is an advantage that not only does a textile material usually have an objectively lower heat capacity than a metal, but it is also not expected to have a high surface temperature. Thus, the ironing shoe, which has a textile material on the ironing surface, intuitively usually be used when on a sensitive ironing a particularly low working temperature is sought. An iron-toed shoe with a metal sole would be used intuitively for a slightly higher working temperature range.
  • The textile material of the ironing surface should come into direct contact with the material to be ironed. In order to ensure direct contact with the ironing material, the textile material is provided at least over a part of the ironing surface away as the outermost layer. For example, more than 50% or more than 75% of the ironing surface are provided with the textile material. The ironing shoe may in particular also have an ironing surface which is completely covered with the textile material. Then a direct contact between textile material and items to be ironed is possible over the entire ironing surface.
  • A variety of textile materials is suitable, in particular polyester and polyamide are suitable (preferably with a continuous temperature resistance of more than 160 ° C). The textile material should therefore contain polyester or polyamide or may also consist entirely of polyester or polyamide. Since an iron shoe is proposed, the relatively low operating temperatures achieved, no unusually temperature-resistant, and therefore expensive material must be used. Thus, an ironing shoe is proposed, which does not require highly heat-resistant textile materials, in particular no "Nomex" or "Kevlar" or aromatic polyamide and further contains no Teflon (neither fluorinated ethylene polymer, nor tetrafluoroethylene) or must contain.
  • The textile material may be in various forms, such as a non-woven material or as a woven material but also as a knitted fabric. A knitted fabric is understood as meaning a textile material made from a continuous thread. The textile material preferably forms a smooth, wrinkle-free surface.
  • The ironing shoe has a base body, which may comprise at least one frame. The textile material can span this frame. Alternatively or additionally, the use of at least one second frame or a support plate is proposed. These can then form the basic body together with the first frame.
  • The at least one frame may be made of a variety of materials, such as metals, especially non-ferrous metals and aluminum. Two or more frames can be made of the same or different materials. There are also plastic materials into consideration, which are sufficiently resistant to heat should, but in particular should be dimensionally stable when exposed to heat. So there are various thermoplastics into consideration, for example, polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
  • Alternatively or in addition to one or more frames, the base body may also comprise a carrier plate. For the usability of the ironing shoe with a steam iron, the backing plate should have a sufficient number and type of vapor passages.
  • The support plate may also be made of plastics or metal. It can be the same as one or all of the frame materials or a different material. The support plate may in particular be made of metals, non-ferrous metals and aluminum. An aluminum support plate has the particular advantage that it is very dimensionally stable under the action of heat. The use of such a support plate can thus greatly increase the heat resistance of the base body and thus of the entire iron shoe.
  • Alternatively or in addition to the described mechanical passage through a gap, the textile material can be connected to the main body, in particular to the frame. Considered for the compound are the hot deformation or bonding or ultrasonic welding. In one embodiment of the iron shoe, therefore, the textile material is ultrasonically welded to the frame.
  • The frame can be attached in a variety of ways to the support plate, for example by mechanical connection or by adhesive bonding. A preferred type of connection is to provide in the support plate recesses can be passed through the attachment tabs of the frame.
  • An ironing shoe according to the present invention is suitable for a significant reduction of the working temperature between the soleplate and ironing material. When an ironing shoe according to the invention is placed on an iron soleplate with a temperature of 200 ° C., the working temperature is reduced by the shoe, for example, to a range of 80 ° C. to 160 ° C. or else to a range of 80 ° C. to 120 ° C. , In an iron shoe comprising a support plate, an air gap can remain between the support plate and the textile material of the ironing surface. The air gap, z. B. a gap of 5 mm to 10 mm or 2 mm to 5 mm or 2 mm to 3 mm, then ensures a further reduction of the working temperature.
  • Alternatively or in addition to an air gap, a foam layer may also be provided between the carrier plate and the textile material. Such a situation reduces the ironing temperature and conveniently passes on the pressure exerted by the iron contact pressure on the textile material. A foam material should be sufficiently permeable to steam. A hydrolysis-based foam, in particular polyurethane, can form a good foam layer.
  • The iron shoe at least one fastening device is provided which allows the direct or indirect attachment of the ironing shoe to an iron. In addition to the attachment of the ironing shoe on the iron is indeed the attachment of the disclosed here iron shoe on another ironing shoe into consideration. The use of two iron shoes can reduce the temperature particularly quickly and effectively.
  • The fastening device may be an integral part of the base body or provided separately and connected to the base body. The fastening device can be in one piece or in several parts. In a multi-part fastener, it is contemplated that one element of the fastener be positioned at the sole tip while one or more other elements are positioned at the opposite end of the ironing surface.
  • The main body of the ironing shoe can be shaped in its front, usually pointed area so that an iron soleplate or another iron shoe can be used and is embraced by the body in a form-fitting manner. This is particularly well possible if the base body and the body to be used on its upper side are similar in their cross section, wherein the main body of the soleplate has the slightly larger cross-sectional area. In a longitudinal axis view, a curvature of the main body should at the same time arise, which can receive the body to be connected positively and prevents removal of this body upwards. Such a wraparound may be an integral part of the body, for example, be formed from the carrier plate, or may be provided by a separate component.
  • The fastening devices at the rear end of the ironing shoe may in particular comprise a hook or wraparound, which is mounted resiliently. The fastening device (s) should preferably (s) the insertion of the slab iron by the mere exercise of pressure (and possibly also the insertion of an already shoeed with a first shoe iron). Furthermore, the fastening device allows the fast and secure detachment of the shoe, possibly with only one hand.
  • It comes as mentioned into consideration that ironing several ironing shoes are used in combination. This may be an iron shoe with metallic sole, z. B. in the EP 1 031 655 described ironing shoe in combination with an ironing shoe with an ironing surface which has a textile material. Although an identification of the individual ironing shoes after the working temperature reached with the shoe comes into consideration, it is even more advantageous for the appearance of the ironing shoe intuitively to prompt the correct use. It is therefore also within the scope of this invention to provide an ironing shoe in which the fastening device is designed to fasten the ironing shoe to another ironing shoe.
  • The invention will now be explained with reference to figures. Such features, which can be technically combined in a different way, but are unavoidably disclosed in the figures with further features, are also to be disclosed individually. It shows:
  • Fig. 1
    a view of an iron shoe according to the invention from below
    Fig. 2
    a view of the shoe from above (ie from the direction from which an iron is put on)
    Fig. 3
    a view of the ironing shoe from the side
    Fig. 4
    an exploded view of the essential elements of the ironing shoe
  • The Figure 1 (Fig. 1 ) shows the ironing shoe (10) from its underside, so you can see on the side with which the ironing shoe is applied to the fabric. The underside is completely covered with a textile material (12). The textile material (12) is mounted on the frame (14). In this case, the textile material (12) is stretched so far that a flat, wrinkle-free surface is formed. The textile material (12) is folded around the side edges of the frame (14) and fixed on the non-visible side of the frame (14). In the presentation of the illustration 1 the frame (14) can be seen from below. The illustration is schematic in so far. Depending on the choice of textile material (12), the frame (14) may shine through or may not shine through. The described attachment of the textile material (12) on the frame (14) allows that the frame (14) does not directly touch the ironing material, so that therefore the ironing surface is completely covered with the textile material (12). The illustration 1 further shows a fastener (16) securing the releasable attachment of the shoe (10) to the soleplate. This fastener (16) is mounted opposite the tip.
  • The Figure 2 shows the ironing shoe (10) from above. Here it is visible that the fastening element (16) cooperates with a wrap (24). In this wraparound (24), the tip of the soleplate can be used. The wrapper (24) can be rigid. The fastening element (16) can then have, for example, a spring-mounted snap closure. In the figure, the support plate (18) of the iron shoe (10) is also recognizable. This carrier plate (18) has a plurality of vapor passages (20). The vapor outlets (20) may be arranged in different densities, for example there may be in the vicinity of the ironing tip a zone with more vapor passages per unit area than in at least one other zone further away from the temple tip. The support plate (18) is partially covered by an inner plate (22). However, this inner plate (22) has windows through which steam exiting the soleplate reaches the vapor passages (20).
  • Figure 3 shows a side view of the ironing shoe (10). In this figure, also the rear fastener (16) and the corresponding and cooperating front Umgriff (24) can be seen. Although the carrier plate (18) is substantially planar, it can still be bent up laterally. It can therefore be seen in this figure on the side surfaces of the support plate (18). On the underside of the support plate (18) of the frame (14) is applied.
  • Figure 4 shows an exploded view of the iron shoe (10). Shown below is the textile material (12). Above this is the frame (14). On the frame (14) upward attachment lugs are visible. The textile material (12) is beaten outside the frame (14). It can then be secured to the top of the frame (14), for example on the flat surfaces between the attachment lugs. It may also be advantageous to provide a groove for the purpose of securing the textile material (12) to the top of the frame (14). The textile material (12) can be inserted in this groove be and further attached there in a suitable manner. This is about the ultrasonic welding.
  • The frame (14), which is connected to the textile material (12) forms a kind of receptacle, which is laterally bounded by the frame (14) and down through the textile material (12). In this tub, a foam insert (28) can be inserted. The foam layer (28) can be adjusted in height to the height of the frame (14).
  • On top of the frame (14) and possibly on the foam layer (28), the support plate (18) is placed. Like in the Figure 4 visible, this support plate (18) next to and independent of the steam outlets (20) recesses into which the fastening lugs of the frame (14) can be guided. The support plate (18) may further, for example, also in the form of suitable recesses, means for connecting the support plate (18) with the fastening element (16). The carrier plate (18) can also receive the wraparound (24) at its tip.
  • The side surfaces of the support plate (18) are formed into walls of low height, so that the support plate (18) has a trough shape. Therefore, in the top of the support plate (18) well an inner plate (22) can be introduced. The inner plate (22) has windows which are matched to the position of the steam passages (20). The inner plate (22) may, like the carrier plate (18) consist of a stamped sheet metal, which is bent at the sides and also around the windows. Between the support plate (18) and the inner plate (22) another textile material (26) are inserted. For this purpose, for example, a felt into consideration, which is tailored so that the windows in the support plate (18) are not obscured and can be glued to the support plate (18).
  • The featured ironing shoe offers a textile ironing surface for gentle ironing with optimum performance properties - especially when steam ironing - on.
