FIGS. 1 and 2 show an ironing apparatus, of the steam generator type, conventionally comprising an iron 1 resting on a portable base 2 incorporating, in a manner known per se, a vessel for producing steam under pressure, not shown in the figures, the base 2 being electrically powered by means of a cable 24.

The iron 1 comprises a heating soleplate surmounted by a one-piece plastic body incorporating a handle 11, the latter extending towards the rear of the iron by two arms 12 comprising a rear face constituting the heel of the iron, the body having a portion of cantilever extending between the sole 10 and the heel of the iron. The handle 11 is conventionally extended towards the front of the iron by a nose covering the front tip of the sole 10, the iron 1 being connected to the base 2 by a flexible cord 3 incorporating electrical supply wires of the heating soleplate 10 as well as a steam supply duct 10 of the iron soleplate. The base 2 comprises a flat bottom surface intended to rest on a horizontal plane and has an inclined upper surface 21 comprising a recess constituting a location 21A for resting the iron 1, this location 21A comprising an inclined plane bottom of the order of 30 ° relative to the lower surface 20 and having pads 21B projecting to thermally isolate the base 2 of the sole 10 of the iron.

The upper surface 21 of the base 2 comprises, in front of the location 21A, a panel 23 for controlling the apparatus and encloses, in the space located under the location 21, a reservoir intended to supply water to the tank for production. the tank being provided with a filler door 25. In order to allow the immobilization of the iron 1 on the base 2, the base 2 comprises, at the foot of the location 21A, a bumper 22 on which the heel of the iron comes to bear when the iron 1 is placed on the location 21A, the stopper 22 advantageously having an outgrowth 22A being inserted into a cavity 13 formed on a lower face of the cantilever portion located at the rear of the iron 1 so as to immobilize laterally and vertically the rear part of the iron 1 in the location 21A.

The front part of the iron 1 is immobilized on the base 2 by means of a hoop 4 pivotally mounted at the portion of the location 21A receiving the front tip of the sole 10 of the iron, the hoop 4 having advantageously a triangular shape conforming to the contour of the front end of the location 21A.

The hoop 4 can pivot between a folded position, illustrated in Figures 2 and 6, wherein the hoop 4 is engaged in a receiving groove formed at the edge of the location 21A, being disposed parallel to the upper surface 21 of the base, and a position of immobilization of the iron, illustrated in Figures 1 and 8, wherein the arch 4 bears against the upper surface of the nose of the iron 1, the arch 4 advantageously having a flexible portion 40 reported overmolding in the hollow part of the arch 4 coming into contact with the iron body 1 to be ironed when the arch 4 is in the immobilization position. In accordance with FIGS. 3 to 4, which represent in isolation the subassembly defining the upper surface 21 of the base, the arch 4 is preferably constituted by a plastic part comprising two branches, defining an inverted V, having a lower end passing through an opening 26 formed on the upper surface of the base 2 to be pivotally mounted on an axis 5 disposed within the base 2, the axis 5 being carried by tabs 27 projecting under the upper surface of the base 2. More particularly according to the invention, the base 2 comprises return means 6 exerting a return torque on the arch 4 whose direction reverses when passing from an intermediate position, illustrated in FIG. 7, located between the folded position and the immobilization position, the return torque bringing the hoop 4 back to the folded position when the latter is in an angular position situated between the folded position and the t the intermediate position and bringing the hoop 4 to the immobilization position when the latter is in an angular position between the intermediate position and the immobilization position. The return means are advantageously constituted by two helical torsion springs 6 arranged near the lower end of the branches of the arch 4, each spring 6 having a first curved end engaging in a hole 28A formed in a support stud 28 protruding under the upper surface 21 of the base and a second curved end engaging in a notch 41 formed at the edge of the leg of the arch 4.

According to FIGS. 6 to 8, the notch 41 is formed along the edge of the arch 4 so that the notch 41 is located above the line passing through the orifice 28A and the axis 5 of rotation. when the hoop 4 is in the folded position, illustrated in Figure 6, and is below the line d when the hoop 4 is in the immobilization position illustrated in Figure 8, wherein the hoop 4 advantageously forms an angle of the order of 50 ° with respect to the bottom of the location 21A, the notch 41 being aligned with the line d when the arch 4 occupies an intermediate position, illustrated in FIG. which the arch advantageously forms an angle of the order of 20 ° relative to the bottom of the location 21A.

Preferably, the arch 4 also comprises a stop 42 which abuts against an edge 26A of the opening 26 to limit the pivoting stroke of the arch 4 in a stop position, not shown in the figures, located slightly beyond the immobilization position. The operation of the return means of the locking arch will now be described. When the hoop 4 is disposed in the folded position illustrated in Figure 6, the spring 6 exerts a restoring torque in the direction Rt which tends to maintain the hoop 4 in the folded position. If the user wishes to lock the iron 1 on the base 2, he places the iron 1 on the location 21A by resting the sole 10 on the pads 21B and engaging the protrusion 22A of the stopper 22 in the cavity 13 located at the rear of the iron, then manually grasped the hoop 4 so as to lift to the intermediate position shown in Figure 7, by counteracting the return torque exerted by the springs 6, the return torque gradually decreasing to become zero at passage of the intermediate position. When the hoop 4 is manually brought above the intermediate position, the restoring torque exerted by the springs 6 is reversed, the springs 6 then exerting a restoring torque in the R2 direction which increases gradually as and when that the arch 4 approaches the locking position in which it abuts against the nose of the iron 1 to iron. Thus the user can release the hoop 4 when the latter is raised beyond the intermediate position, the springs 6 then automatically bringing the hoop 4 against the nose of the iron 1. In the locking position, the hoop 4 is applied against the upper face of the body of the iron 1, so that it results in a perfect immobilization, without deflection, the iron 1 on the base 2. The user can then transport the generator by grasping the handle 11 of the iron. If the hoop 4 is raised beyond the intermediate position while the iron 1 is not disposed on the location, the hoop 4 pivots under the effect of the couple of springs 6 of return until the abutment 42 at the base of the arch 4 is in abutment against the edge 26A of the opening 26, thus preventing the arch 4 from tilting too much towards the rear of the base 2. When the user wishes to use the iron 1 to iron, it is sufficient to grasp the arch 4 to move away from the nose of the iron 1, exerting a force greater than the restoring torque exerted by the springs 6 of return, this effort decreasing gradually as and as the arch 4 approaches the intermediate position. When the hoop is below the intermediate position, the user can release the hoop 4, the latter being automatically returned by the return springs 6 in the folded position.

Such an iron locking device on the base of the generator thus has the advantage of being both simple design and very ergonomic use. In particular, the risk of damage to the locking device when the user forces on the rollbar to bring it from the locking position to the folded position is eliminated. Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention. Thus, in an alternative embodiment not shown in the figures, the stop of the bow can be arranged in such a way that the stop position of the bow in which the stop abuts on the edge of the opening corresponds to at an immobilization position of the iron in which the hoop is in the immediate vicinity of the iron without affecting the latter. Thus, in an embodiment variant not shown, the vessel for the generation of steam under pressure may be replaced by an instantaneous vaporization chamber, the latter may be arranged in the base or in the iron and be connected to a reservoir contained in the base by a water pipe. Thus, in an alternative embodiment not shown, the iron may be replaced by a steam brush.
