BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a soleplate for an iron comprising a heating body made by casting and having a peripheral edge of triangular profile defining a nose and a heel, as well as a metallic ironing plate of complementary shape having a pointed forward region and a rear region matching the heel, and which comprises an internal surface adapted to come into thermal contact with the internal surface of the heating body, an external surface having a cladding to form an ironing surface, and a raised edge which surrounds laterally the peripheral edge of the heating body and which comprises assembly means with said edge.
BACKGROUND OF THE INVENTION
In known soleplates for irons of this type, the cladding of the external surface of the ironing plate is relatively fragile, which is to say that it resists only poorly mechanical stresses inflicted during assembly of the plate on the body; this is all the more true when the cladding is of the enamel or chrome type.
Thus, for example, in the case of assembly of the edge on the body, there is created at the level of the bend microcracks which not only impair the appearance but also give rise eventually to oxidation which spreads over the ironing surface.
Moreover, there are also known soleplates for irons in which the ironing plate is fixed by resilient snapping on the heating body.
Although this solution overcomes the problem of microcracks, it requires precise fabrication to provide for assembly, during molding of the heating body, which prevents mass production.
The invention has particularly for its object to overcome these drawbacks.
SUMMARY OF THE INVENTION
According to the invention, the assembly means of the edge comprise at least in the forward region of the edge a preformed and rolled edge adapted to cap the point of the heating body, and in its rear region at least one hook adapted to come into engagement with the heel of the edge of the heating body.
Thus, starting from a plate whose edge is preformed and rolled before depositing the cladding and by limiting the force on the edge solely to the end regions of the ironing plate, regions which are particularly rigid because they are practically points, there is created a simple and economical soleplate adapted for mass production and which preserves for the plate the quality of its cladding without alteration in the course of time.
BRIEF DESCRIPTION OF THE DRAWINGS
The characteristics and advantages of the invention will become further apparent from the description which follows, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a schematic vertical cross-sectional view on the broken line I--I of FIG. 2, of a soleplate according to the invention comprising a heating body and an ironing plate;
FIG. 2 shows in plan view the soleplate of FIG. 1;
FIG. 3 shows in plan view the ironing plate alone;
FIG. 4 shows the heating body and the ironing plate in one phase of assembly of the soleplate according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
The soleplate for an iron, as shown in FIGS. 1 to 4, comprises a heating body 1 made by casting, generally molded in one piece from aluminum and comprising a shielded electric resistance 2. As shown particularly in FIG. 2, the heating body 1 has a peripheral edge 4 with a generally triangular profile defining a nose 6 and a heel 8. This peripheral edge 4 is substantially flat and has a relatively small and regular thickness except in its heel portion, which is slightly thicker.
The soleplate comprises moreover a metallic ironing plate 10 of a shape complementary to the profile of the heating body 1 and thus having a forward pointed region 12 and a rear region 14 forming a heel. The plate comprises an internal surface 16 adapted to come into thermal contact with the lower surface 18 of the heating body, and an external surface 20 clad with a cladding 22 to constitute an ironing surface, and a raised edge 24 which surrounds in height the peripheral edge 4 of the heating body 1 and which comprises a
