[0036] FIG. 6 is a representation of part of an assembly according to the invention, comprising, on the one hand, a steam iron and, on the other hand, an upper part of a table according to yet another embodiment of the invention; and

[0037] FIG. 7 is a sectional view of the layer of plastics material, in the form of a bubble film folded over on itself, of the embodiment in FIG. 6.

[0038] The figures show ironing tables according to a plurality of embodiments of the invention.

[0039] In the conventional manner, the ironing table comprises two legs 1 and 2, assembled such that they are articulated against one another following an axis 3 and supporting a board 4 by means of two longitudinal metal rails 5 fixed by screws to the lower face of the board 4, the upper end of one 1 of the legs comprising a rod 6 fitted such that it slides along the rails 5, whereas the end 7 of the other leg 2 is pivotally attached to the board 4, in particular by means of the two rails 5.

[0040] An iron rest 8 is attached to the board 4 on the side thereof, particularly by screws attaching lugs originating from the iron rest to the rails 5, which are themselves attached to the lower face of the board 4.

[0041] A rack 9, comprising teeth facing the board 4, is pivotally mounted with respect to an axis 10 fixed to the rails 5, a lever 11 allowing the user to pivot the rack to allow the height of the board to be adjusted in the deployed position of the table by choosing the two teeth of the rack between which the rod 6 is received.

[0042] Teeth that have a large fixing profile can be provided, particularly covering over half the rod 6, so as, in addition, to ensure that the rack is locked and cannot be unlocked unless the legs 1 and/or 2 are lifted off the ground, this mechanism traditionally being referred to as a child safety lock. However, this child safety mechanism can be omitted without departing from the scope of the invention.

[0043] The board 4 is made of a wooden material, in particular plywood, chipboard, oriented strand board or OSB, MDF (medium-density fibreboard), in particular OSB.

[0044] The board 4 is covered in its entirety by a bubble film 15, the upper face of which, opposite the board, comprises a metallising layer 16, particularly aluminium. The bubble film comprises an elastic bias binding 24 sewn around its periphery to hold it tightly in position around the wooden board 4, against the upper face of said board.

[0045] An outer covering 12 made of textile material, particularly cotton, then covers the entire board 4 made of wooden material by means of a drawstring cord passing in a ring 23 formed on a hem 22 sewn around the periphery of the covering 12, the two ends of the cord leaving the ring via an opening formed therein to thus allow them to be tied together to pull the covering tightly against the board from beneath said board. Instead of such a cord, an elastic thread or ribbon received in the peripheral ring could also be provided, allowing the covering to pass over the edge of the board 4 to then be supported elastically against the lower face of the board. It would also be conceivable, as in the case of the bubble film, to sew the thread or ribbon, such as elastic bias binding 24, along the periphery of the hem of the cover and thus omit the peripheral ring.

[0046] In the embodiment in FIGS. 1 and 4, a thermally insulating flexible element in the form of a fleece or felt fabric 14 is provided between the outer covering 12 made of textile material, particularly cotton, and the bubble film 15 in contact with the upper face of the board 4.

[0047] According to another embodiment shown in FIG. 3, a thermally insulating flexible element in the form of a sheet 13 of cellular material or foam is arranged between the covering 12 and the bubble film 15 in contact with the upper face of the board 4.

[0048] According to yet another embodiment shown in FIG. 5, a thermally insulating flexible element in the form of both a sheet 13 of cellular material or foam and a fleece or felt fabric 14 is arranged between the covering 12 and the bubble film 15. In FIG. 5, the sheet 13 and the fabric 14 are shown on top of the covering 12 so that they are visible. However, in use, the assembly 12, 13, 14 shown is turned in the opposite direction to that shown on the figure so that it is positioned on the board with the fabric 14 in contact with the metallising layer 16 deposited on the film 15, the covering 12 forming the outermost part, the sheet 13 and the fabric 14 being trapped between the covering 12 and the board 4 covered with the film 15, which is itself covered by the metallising layer 16.

[0049] Thus, the stack on top of the board 4 is comprised, starting from the board 4, of the bubble film 15, in contact with the upper surface of the board 4, the metallising layer 16 joined to the bubble film 15, the fleece or felt fabric 14, the layer 13 of cellular material or foam, and finally the cotton covering 12, the upper surface of which forms the upper ironing surface of the ironing table.

[0050] According to the embodiment shown in FIG. 5, the covering 12 and the flexible thermally insulating element in the form of the sheet 13 of cellular material or foam and the fleece or felt fabric 14 are joined together to form a single covering element forming an ironing table cover, this joining being achievable in particular by hot calendering, thermowelding, sewing, ultrasonic welding or any other method. In particular, to manufacture the cover comprising three elements 12, 13 and 14, a width or strip of a textile fabric 12 can be unrolled from a roll of said textile fabric 12, particularly cotton, a strip or width of a lap 13 of cellular material or foam can be unrolled from a roll of said lap, the strip or width being identical to that of the textile fabric, a strip or width of a fleece or felt fabric 14 can be unrolled from a roll of said fabric or felt, the strip or width being identical to that of the textile fabric and the lap of cellular material, the lap 13 of cellular material can be softened, in particular by singeing, particularly on both faces thereof, a stack of the three strips or widths together, with the softened lap arranged between the textile fabric and the fleece or felt, can be passed between two pressing elements, for example two rollers, in order to calender it and achieve joining in the form of a laminate of the same strip or width made up of the textile fabric, the lap of cellular material and the fleece or felt. Then, after calendering, the laminate is cut around a pattern in the shape of the contour of a board for which the intention is to produce a covering cover plus a peripheral selvedge, then the cut laminate is provided with means to movably attach the laminate to said ironing table board, in particular in the region of the peripheral edge of the laminate, for example by sewing along the entire periphery of the cut laminate a hem 22 comprising a peripheral ring 23 in which a cord extends, both ends of the cord leaving the ring via an opening formed in said ring to thus allow them to be tied together to pull the covering tightly against the board from beneath said board. Instead of a cord, an elastic thread or ribbon received in the peripheral ring of the hem may be provided, allowing the textile fabric to pass over the edge of the board to then be supported elastically against the lower face of the board. An elastic thread or ribbon could also be sewn on the hem 22, which is itself sewn to the periphery of the laminate.

[0051] However, this arrangement, although it is very favourable, is merely optional and the present invention is not restricted thereto, the elements being able to be independent from one another, the sheet 13 and the fabric 14 being positioned on the bubble film 15, then trapped by positioning the outer covering 12 around the assembly of the board 4, bubble film 15 with metallising layer, fleece 14 and cellular material or foam 13. Moreover, although this arrangement is favourable, it is also possible to merely provide the sheet 13 of cellular material or foam or only the fleece or felt fabric 14 without departing from the scope of the invention.

[0052] The insulating flexible element in the form of the sheet 13 of cellular material or foam and/or the fleece or felt fabric 14 serves to protect the bubble film 15. The bubble film 15 is a traditional bubble film made up of a number of domes, each defining a small bubble or airtight space in which air is trapped. The bubbles are arranged in rows and columns, each model having a diameter ranging between 5 and 15 mm, in particular equal to 10 mm. The number of bubbles per square metre may, for example, be 17,200.

[0053] FIG. 6 shows an assembly according to the invention, comprising, on the one hand, a steam iron 20 and, on the other hand, a cover 21, consisting of a covering 12 and a thermally insulating flexible element in the form of a sheet 13 of cellular material or foam (not visible on FIG. 6) and a fleece or felt fabric 14 joined to one another by calendering, after singeing the cellular sheet to soften it and thus allow the two elements to be joined together after calendering, the cover 21 then covering a bubble film 15 with a metallising upper layer 16, the bubble film 15 being trapped between the cover 21 and the board 4 of the table.

[0054] FIG. 7 shows a sectional view of the bubble film 15 from FIG. 6. The bubble film 15 comprises, on one of its faces, opposite the domes, a metallising layer 16. The bubble film 15 is folded over on itself such that the metallising layer forms the two upper and lower faces of the folded bubble film 15, the bubbles of said bubble film 15 then being sandwiched between the two upper and lower metallising layers, the lower metallised layer then being in contact with the board, whereas the upper metallised layer is in contact with the fleece fabric or the layer of cellular material or foam, depending on the embodiment. Preferably, the domes or bubbles of the two folded parts are attached to one another, in particular welded, glued or similar.

[0055] The bubble film material may, in particular, be LDPE (low-density polyethylene), HDPE (high-density polyethylene), LLDPE (linear low-density polyethylene), Resy (recycled materials) or a blend of these materials, in particular a blend of LDPE 70%/HDPE 10%/LLDPE 10%/Resy 10%. The thickness of the bubble film may be selected between 1 and 10 mm, in particular between 2 and 5 mm, for example 3.2 mm.

[0056] The bubble film has been aluminised by depositing a film or a layer of aluminium, where said deposition can take place by coating, lamination, stratification or another similar process.

[0057] For example, the aluminium film or layer may be a co-extruded metallised BOPP (biaxially oriented polypropylene) film, laminated on one face of the bubble film and having an aluminium thickness of between 0.01 mm and 0.02 mm, in particular equal to 0.015 mm and a plastics material ranging between 100 and 200 g/m2, in particular equal to 110.4 g/m2, i.e. a plastics material thickness ranging between approximately 0.1 mm and 0.2 mm.

[0058] The layer of cellular material or foam may in particular be made of polyurethane (PU), in particular with a surface density ranging between 18 g/m.sup.2 and 45 g/m.sup.2, with a thickness between 1.5 and 2.5 mm, for example 1.8 mm, if used in combination with another flexible insulating element, for example a fleece or felt, and a surface density ranging between 50 g/m.sup.2 and 250 g/m.sup.2, with a thickness between 5 mm and 10 mm if used in isolation to form the insulating flexible element.

[0059] The fleece or felt layer, particularly made of wool or polyester, may have a surface density ranging between 150 g/m.sup.2 and 300 g/m.sup.2.

[0060] The steam ironing device may be defined by the fact that it comprises a water tank and heating means to vaporise this water and means to project this vapour with a pressure of at least 2 bar, preferably at least 3.5 bar, particularly between 3.5 bar and 10 bar, the steam flow preferably being at least 40 g/min, particularly at least 50 g/min, preferably at least 100 g/min, in particular between 200 g/min and 500 g/min.

[0061] According to the invention, the material of the layer of plastics material is substantially impervious to water vapour.

[0062] According to the invention, a flexible element is understood to mean an element that can easily be folded and folded again, without it breaking or experiencing damage, in particular an element that, when it is held simultaneously at two different locations by the hands of a person of moderate strength, can be deformed, particularly by folding, and can then resume the shape it was in before it was deformed, in particular folded.
