Definitions

• the invention relates to an iron soleplate comprising a heating body from the foundry and having a peripheral edge with a triangular profile defining a point and a heel, as well as a metal ironing plate of complementary shape having a pointed anterior region. and a posterior region conforming to the heel, and which has an internal face intended to come into thermal contact with the lower face of the heating body, an external face having a coating to form an ironing surface, and a raised edge which laterally surrounds the edge peripheral of the heating body and which comprises means of assembly with said edge.
• the coating of the external face of the ironing plate is relatively fragile, that is to say it does not withstand the mechanical stresses inflicted during assembly of the plaque on the body; this is all the more important when the coating is of the enamel or chrome type.
• iron soles are also known in which the ironing plate is fixed by elastic snap-fastening on the heating body.
• the means of assembling the border comprise at least in the anterior region of the border a preformed and rolled edge intended to come to cap the tip of the heating body, and in its posterior region at least one hook intended to come engaging the heel of the edge of the heating body.
• FIG. 1 is a schematic view in vertical section along the broken line I / I of Figure 2 of a soleplate according to the invention comprising a heating body and an ironing plate; 2 shows a top view of the sole of Figure 1;
• FIG. 3 illustrates a top view of the ironing plate alone;
• FIG. 4 shows the heating body and the ironing plate in an assembly phase of the sole according to the invention.
• the soleplate of iron as shown in FIGS. 1 to 4 comprises a heating body 1 from the foundry, generally molded from a piece of aluminum and incorporating an armored electrical resistance 2.
• the heating body 1 has a peripheral edge 4 with a general triangular profile defining a point 6 and a heel 8.
• This peripheral edge 4 is practically flat and has a relatively thin and regular thickness except in its region which is slightly larger.
• the sole further comprises a metal ironing plate 10 of shape complementary to the profile of the heating body 1 and thus having a pointed anterior region 12 and a posterior region 14 forming a heel.
• Said plate has an internal face 16 intended to come into thermal contact with the lower face 18 of the heating body, and an external face 20 coated with a coating 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 means of assembly with said edge.
• This plate 10 is preferably made of steel and the coating 22 of the plate 10 is, for example, made of a layer of enamel or chromium which ensures a very good sliding of the sole on different textiles.
• This sole thus formed can be fitted with either a dry type iron or a steam iron in which the plate 10 has, in a manner known per se, a plurality of steam outlet holes as shown diagrammatically in broken lines on the figure 3.
• a layer of silicone adhesive is applied to the lower face 18.
• the means of assembling the border 24 comprise at least in the front region 12 of the border a preformed and rolled edge 26 intended to come to cap the tip 6 of the heating body, and in the posterior region 14 at least a hook 28 intended for engaging with the heel 8 of the edge 4 of the heating body.
• the latter has two hooks 28 as illustrated in FIG. 2.
• each hook 28 has a tab, part of which is folded in the direction of the central region of the heating body 1.
• these hooks are obtained by notches 30 made in the edge 24 so as to allow the folding of the parts 29 of the legs.
• the hook 28 is an elastic element intended to automatically snap onto the heel, this elastic element possibly being a tab coming from the edge 24 and having a lateral boss forming a clip.
• the plate 10 previously shaped and coated with a fragile coating, enamel or chrome is fixed to the peripheral edge 4 of the heating body at its ends, toe and heel, without damaging the coating of the border. 24 and therefore the coating of the ironing surface.
• the preformed and rolled edge 26 in the vicinity of the point has, by its triangular shape at an acute angle constituting a pocket, a rigidity which prevents any deformation of the edge and therefore any local elongation of the coating, and consequently avoids the creation of micro-cracks.
• the stresses exerted on the hooks 28 are very localized and are exerted only on the horizontal parts 29 of the tabs which, at the end of manufacture of the iron, will be hidden by the housing.
• the rolled edge 26 of the edge 24 also extends laterally to the large lateral edges 32 of the heating body, and at a distance from these edges according to a small clearance ⁇ . This avoids a precise adjustment of the dimensions of the heating body and of the border which is difficult to obtain, in particular during the casting operation of the heating body.
• the plate 10 thus completed and the heating body 1 are maintained at an angle ⁇ .
• the point 6 of the edge 4 is fitted under the rolled edge 26 of the anterior region of the edge 24.
• the lower 18 and inner 16 faces of the heating body 1 and the plate 10 are applied against each other respectively and the assembly thus formed is maintained by the positioning of the hooks 28 on the heel 8.
• This hooks are put in place by folding the parts 29 on the heel 8.
• This fixing around the pivot point formed by the tip 6 and the rolled edge 26 allows an almost intimate application by the layer of silicone adhesive with the face lower 18 of the heating body since the application force is controlled at the level of the hooks 28.
• this process offers as main advantages the simplicity of manufacture, and the guarantee the quality of the ironing surface both in manufacturing and in long-term use.
