Definitions
- the present invention relates to the general technical field of apparatus designed to shape a textile article such as clothing, by subject to the combined action of heat treatment, mechanical treatment ironing and possibly a steam treatment.
- the present invention relates to an iron comprising a heating body, a sole associated with the heating body, a heating circuit, associated or not with a vaporization chamber.
- the thermal energy transmitted to the soleplate ironing is conventionally provided by heating elements such as tubular heating elements or by flat type heating elements including a resistive track.
- the resistive track forms a circuit of heating defining a heating zone on the ironing sole, said track being inserted between two films of electrical insulation adhering against each other and now also in place the resistive track.
- means of temperature regulation or sensors for example a thermostat, arranged in the iron in thermal relation with the heating element.
- the present invention relates to the soles of such irons, more particularly at the outer surface of these intended to be in contact with the laundry.
- the iron soles currently on the market are conventionally made from an aluminum alloy foundry piece constituting the body heater, comprising the heating element and whose outer surface intended to be in contact with the linen is emery and / or polished. This solution relatively old tends to disappear because giving performance poor sliding and ease of maintenance.
- Aluminum or enameled copper soles have also been proposed, having good sliding performance and ease of maintenance. Through against, for such soles, resistance to wear and impact, in particular edges is much worse than in the aforementioned case of stainless steel.
- the object of the invention is to produce an iron soleplate in combining at least two materials in such a way as to combine the advantages depending on the optimal characteristics sought for each area of the sole.
- its object is to produce a sole whose surface material lower, in particular the central portion of the sole, is selected so as to give priority to sliding and cleanability, the leading edge or edges of said sole being made of a material favoring above all impact resistance.
- Another object of the invention consists in making a sole whose characteristics ironing are improved.
- the invention relates to an iron having the characteristics of claim 1.
- the sole is made from two materials: enameled aluminum and stainless steel.
- the edges of the sole are made of stainless steel and the portion substantially central of the sole is aluminum, preferably enameled.
- the sole has better resistance, especially when deposits on the iron rest, because experience shows that it is the edges that are the most exposed.
- the substantially central portion of the enameled sole retains its good sliding properties.
- Figures 1 and 2 illustrate a first preferred embodiment of the iron according to the invention, comprising a vaporization chamber (not shown).
- Chimneys 3 provided in a heating body 4 ensure the delivery of steam from the chamber to the spray ports 2.
- the sole is generally made up by a first material with a low coefficient of friction covering at least in part of its lower surface and having characteristics such as to give it qualities of wear resistance, but especially of sliding and cleanability.
- a second material covers at least a lateral and / or lower part of its contour 4c and has characteristics giving it resistance qualities to shocks.
- the border element 6 covers the lower part of the edge 4c on the one hand, thus forming the lower border the sole 6a; on the other hand, the rim 6 has an extension 6b folded over so as to also cover at least a portion of the lateral edge of the sole.
- the side border 6b is formed by an extension of the bottom edge of sole 6a folded back so as to extend so substantially vertical along the contour 4c. It is understood that the inclination and the height of this portion 6b may vary depending on the construction of the iron. So is even for the width of the portion 6a. According to simplified variants, provision is made for limit the reinforced sole in a first case to the single portion 6a; in one second case, in the single portion 6b.
- the border element 6 is arranged in the zone of the toe 7 of the sole 1.
- the border element 6 can be disposed both in the area of the toe 7 and / or in the area of the heel 8 of said sole, and / or in any other advantageous portion of the contour of the sole, according to the characteristics sought.
- border element 6 surrounds the entire contour. of this sole.
- border element 6 is fixed on the toe 7 and / or the heel 8 of the part lower 4a of the heating body 4, firstly by bonding C of the lower edge 6a against the lower surface 4b of said body 4 and on the other hand by lugs fixing 9 punctually issuing from said rim 6 and able to penetrate into housings 10 of the lower part 4a of the heating body 4 to be there immobilized by twisting.
- Bonding is preferably carried out by means of a silicone adhesive.
- the second variant shown in Figures 3 and 4 differs essentially from the previous one in that the border element 6A is made up of from a strip, shaped to form a U-shaped section profile, closed in on itself and arranged advantageously over the entire contour of the lower part 4a of the heating body 4 for fixing it firmly by crimping peripheral.
- the border element 6A is made up of from a strip, shaped to form a U-shaped section profile, closed in on itself and arranged advantageously over the entire contour of the lower part 4a of the heating body 4 for fixing it firmly by crimping peripheral.
- other types of section could be considered.
- At least one of the branches 11, 12 of the U of the profile constituting the border element 6A, preferably, the lower branch 12, is bonded to the lower surface 4b of the heating body 4 with which it is in contact so as to strengthen its fixation.
- the plate to low coefficient of friction 5 is obtained by cutting a selected material, on which are provided spray orifices 2 further intended to ensure fixing by crimping, of known type, of said plate 5 in holes corresponding 13 of the lower part 4a of the heating body 4.
- This fixing can be reinforced here again by combining a C adhesive with silicone. interposed between the plate 5 and the heating body 4.
- the fixing of the different elements of the sole are produced most often by gluing
- the border element 6 can be made from another type of metal alloy, such as titanium, or from a non-metallic material, such as for example a material of ceramic type.
- plate 5 at low coefficient of friction preferably has a side flange folded upwards. Furthermore, unlike the previous embodiment, this plate occupies advantageously an area corresponding substantially to the entire area of the sole.
- the assembly of the border 6 having good resistance characteristics impact is preferably obtained by stamping or cold striking under strong pressure of plate 6 of relatively hard material against plate 5 of material softer to ensure their connection by interpenetration of materials; the material the softer 5 penetrating into the openings 14 provided in the harder material 6, as shown in Figure 7.
- Other assembly methods giving results similar, such as hot stamping, can also be considered.
- the effect of cold pressing is twofold: there are both penetration of hard material 6 into soft material 5 and creep of soft material which comes to fill the orifices 14 provided in the hard material.
- This filling effect comparable to the installation of a rivet, provides a rigid and durable support.
- the arrangement or the distribution of the orifices can vary according to an infinity of possibilities, depending on the shape of the border 6a, the number of openings 14, their shape, their size, etc.
- the openings are circular. According to various variants, these openings can take a multitude shapes, according to the designer's imagination.
- this method of fixing the strip 6 by interpenetration materials provides an edge effect due to the presence of micro-edges 15 located at the junction of the two materials, at the periphery of the openings 14. It has It has been observed that the presence of these micro-edges 15 has a beneficial effect. on ironing.
- the plate 5 with a low coefficient friction is obtained by cutting an aluminum blank, preferably enamelled, while the border element 6 is preferably made of stainless steel.
- the border element 6 can obviously be made from other types of materials.
- the border element 6 can be manufactured in titanium alloy.
- FIG. 6 illustrates a variant of this latter embodiment where the plate 5 is replaced by the body 4 whose lower surface 4 'is shaped to play the role of plate 5 of the previous embodiment.
- the plate 5 is therefore in fact substituted by the lower surface 4 'of the body 4.
- the material used must obviously lend themselves to cold typing, and meet the requirements for gliding and cleanability desired for the central portion of the sole.
- part of the strip 6 is provided in a material given, at least one other part being made of at least one other material.
- the percentage of relatively soft material flush through the openings used to the hooking can vary considerably, but is generally between 5% and 40 %, and preferably around 20%.
